This multi-method, longitudinal study examines the negotiation of autonomy and relatedness between teens and their mothers as etiologic predictors of perpetration and victimization of dating aggression two years later. Observations of 88 mid-adolescents and their mothers discussing a topic of disagreement were coded for each individual's demonstrations of autonomy and relatedness using a validated coding system. Adolescents self-reported on perpetration and victimization of physical and psychological dating aggression two years later. We hypothesized that mother's and adolescents' behaviors supporting autonomy and relatedness would longitudinally predict lower reporting of dating aggression, and that their behaviors inhibiting autonomy and relatedness would predict higher reporting of dating aggression. Hypotheses were not supported; main findings were characterized by interactions of sex and risk status with autonomy. Maternal behaviors supporting autonomy predicted higher reports of perpetration and victimization of physical dating aggression for girls, but not for boys. Adolescent behaviors supporting autonomy predicted higher reports of perpetration of physical dating aggression for high-risk adolescents, but not for low-risk adolescents. Results indicate that autonomy is a dynamic developmental process, operating differently as a function of social contexts in predicting dating aggression. Examination of these and other developmental processes within parent-child relationships is important in predicting dating aggression, but may depend on social context.

The use of the cognitive capabilties of humans to help guide the autonomy of robotics platforms in what is typically called "supervised-autonomy" is becoming more commonplace in robotics research. The work discussed in this paper presents an approach to a human-in-the-loop mode of robot operation that integrates high level human cognition and commanding with the intelligence and processing power of autonomous systems. Our framework for a "Supervised Remote Robot with Guided Autonomy and Teleoperation" (SURROGATE) is demonstrated on a robotic platform consisting of a pan-tilt perception head, two 7-DOF arms connected by a single 7-DOF torso, mounted on a tracked-wheel base. We present an architecture that allows high-level supervisory commands and intents to be specified by a user that are then interpreted by the robotic system to perform whole body manipulation tasks autonomously. We use a concept of "behaviors" to chain together sequences of "actions" for the robot to perform which is then executed real time.

Architectures and Evaluation for Adjustable Control Autonomy for Space-Based Life Support Systems

2001-01-01

In the past five years, a number of automation applications for control of crew life support systems have been developed and evaluated in the Adjustable Autonomy Testbed at NASA's Johnson Space Center. This paper surveys progress on an adjustable autonomous control architecture for situations where software and human operators work together to manage anomalies and other system problems. When problems occur, the level of control autonomy can be adjusted, so that operators and software agents can work together on diagnosis and recovery. In 1997 adjustable autonomy software was developed to manage gas transfer and storage in a closed life support test. Four crewmembers lived and worked in a chamber for 91 days, with both air and water recycling. CO2 was converted to O2 by gas processing systems and wheat crops. With the automation software, significantly fewer hours were spent monitoring operations. System-level validation testing of the software by interactive hybrid simulation revealed problems both in software requirements and implementation. Since that time, we have been developing multi-agent approaches for automation software and human operators, to cooperatively control systems and manage problems. Each new capability has been tested and demonstrated in realistic dynamic anomaly scenarios, using the hybrid simulation tool.

Intelligent autonomy for unmanned naval systems

NASA Astrophysics Data System (ADS)

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 vehicles and a buoy as surrogate platforms. In addition, a multiple heterogeneous vehicle demonstration was performed using five different types of small unmanned air and ground vehicles. This provided some initial experimentation with specifying tasking for high-level mission objectives and then mapping those objectives onto heterogeneous unmanned vehicles that each have different lower-level autonomy software. Finally, this paper will discuss lessons learned.

Autonomy: Life and Being

NASA Astrophysics Data System (ADS)

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.

[Autonomy, Trust and Medical Ethics in Onora O'Neill's Work].

Jaramillo, Carlos Alberto López; Lew, Jorge Carlos Holguín

2013-03-01

Autonomy has become a key concept in bioethics. Onora O'neill is perhaps the most representative author and researcher in the philosophical and bioethical fields regrding the concept of autonomy. To review the concept of autonomy in Onora O'Neill's work so as to understand its relevance in current bioethics. The concept of bioethics is reviewed in relation to three fundamental quesions: 1) Which are the main limitations of the individualistic conception of autonomy? 2) How to understand the relations between trust and autonomy together with their implications? and 3) Which are the implications of principled autonomy for aspects such as doctor-patient relationship and informed consent. The main works by O'Neill are reviewed, specifically regarding medical bioethics. O'neill's approach is original and relates Kantian autonomy to her own conceptions about trust, and both the individual and social levels of bioethics. The author has developed a Kantian non indvidualistic view of autonomy. Her conceptulization of trust and the crises this concept is currently undergoing complement and strengthen the concept of principled autonomy. The implications of O'Neill's concepts go beyond theoretical discussions and in her work she uses examples and analyzes circumstances which demonstrate the applicability of her proposals. O'Neill's work contributes to dealing with the challenges posed by the socio-political context of cost-efficiency oriented health systems and of the so-called defensive medicine.

UAV Research at NASA Langley: Towards Safe, Reliable, and Autonomous Operations

NASA Technical Reports Server (NTRS)

Davila, Carlos G.

2016-01-01

Unmanned Aerial Vehicles (UAV) are fundamental components in several aspects of research at NASA Langley, such as flight dynamics, mission-driven airframe design, airspace integration demonstrations, atmospheric science projects, and more. In particular, NASA Langley Research Center (Langley) is using UAVs to develop and demonstrate innovative capabilities that meet the autonomy and robotics challenges that are anticipated in science, space exploration, and aeronautics. These capabilities will enable new NASA missions such as asteroid rendezvous and retrieval (ARRM), Mars exploration, in-situ resource utilization (ISRU), pollution measurements in historically inaccessible areas, and the integration of UAVs into our everyday lives all missions of increasing complexity, distance, pace, and/or accessibility. Building on decades of NASA experience and success in the design, fabrication, and integration of robust and reliable automated systems for space and aeronautics, Langley Autonomy Incubator seeks to bridge the gap between automation and autonomy by enabling safe autonomous operations via onboard sensing and perception systems in both data-rich and data-deprived environments. The Autonomy Incubator is focused on the challenge of mobility and manipulation in dynamic and unstructured environments by integrating technologies such as computer vision, visual odometry, real-time mapping, path planning, object detection and avoidance, object classification, adaptive control, sensor fusion, machine learning, and natural human-machine teaming. These technologies are implemented in an architectural framework developed in-house for easy integration and interoperability of cutting-edge hardware and software.

On-water demonstration of a wide range of mission-proven, advanced technologies at TRL 5+ that provide a total integrated, modular approach to effectively address the majority of the key needs for full mission-level autonomous, cross-platform control of USV s. Wide baseline stereo system mounted on the ONR USSV was shown to be an effective sensing modality for tracking of dynamic contacts as a first step to automated retrieval operations. CASPER onboard planner/replanner successfully demonstrated realtime, on-water resource-based analysis for mission-level goal achievement and on-the-fly opportunistic replanning. Full mixed mode autonomy was demonstrated on-water with a seamless transition between operator over-ride and return to current mission plan. Autonomous cooperative operations for fixed asset protection and High Value Unit escort using 2 USVs (AMN1 & 14m RHIB) were demonstrated during Trident Warrior 2010 in JUN 2010

This article discusses autonomy in the lives of adults with intellectual disabilities. The article draws on inclusive research in Iceland with 25 women and 16 men and employs ideas of relational autonomy from the perspectives of the Nordic relational approach to disability. In this article, we examine autonomy in relation to private life, that is, homes and daily activities. The article demonstrates how practices have improved with time and seem less paternalistic. However, the article also demonstrates that the assistance people with intellectual disabilities receive in their homes often has institutional qualities, and they are often met with belittling perspectives from staff and family members. Furthermore, many did not have access to important information needed to develop individual autonomy and independence, including making their own choices. The research findings suggest that people with intellectual disabilities can with appropriate support develop individual autonomy and make their own choices. © The Author(s) 2014.

Integrated System Health Management (ISHM) and Autonomy

NASA Technical Reports Server (NTRS)

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.

Shively, Robert J.

2017-01-01

The NATO HFM-247 Working Group is creating a summary report of the group's activities on human-autonomy teaming. This chapter is a summary of our at NASA Ames work toward developing a framework for human-autonomy teaming (HAT) in aviation. The purpose of this project was to demonstrate and evaluate proposed tenets of HAT. The HAT features were derived from three tenets and were built into an automated recommender system on a ground station. These tenets include bi-directional communication, automation transparency, and operator directed interface. This study focused primarily on interactions with one piece of automation, the Autonomous Constrained Flight Planner (ACFP). The ACFP is designed to support rapid diversion decisions for commercial pilots in off-nominal situations. Much effort has gone into enhancing this tool not only in capability but also in transparency. In this study, participants used the ACFP at a ground station designed to aid dispatchers in a flight following role to reroute aircraft in situations such as inclement weather, system failures and medical emergencies. Participants performed this task both with HAT features enabled and without and provided feedback. We examined subjective and behavioral indicators of HAT collaborations using a proof-of-concept demonstration of HAT tenets. The data collected suggest potential advantages and disadvantages of HAT.

Home care: from adequate funding to integration of services.

PubMed

Hébert, Réjean

2009-01-01

With the aging of the population, the healthcare system needs to shift from the actual hospital-centred system developed in the past century for dealing with acute diseases and a young population toward a home-centred system, more appropriate for serving older people with chronic diseases. Funding of home care should not only be significantly increased but also be managed differently. We propose the introduction of an autonomy support benefit (ASB) to cover costs related to disabilities, irrespective of living environment, and to set up a public universal autonomy insurance program that will cover the ASB. This insurance should be at least partly capitalized to provide for the aging of the population and to ensure intergenerational equity. Also, since the home is a much more complicated service-delivery environment than the hospital, these services must be coordinated and integrated. The Program of Research to Integrate the Services for the Maintenance of Autonomy (PRISMA) is a coordination-type model of integration that was implemented and evaluated in three areas (one urban and two rural) in and around Sherbrooke, Quebec. A four-year longitudinal quasi-experimental study with over 1,500 participants demonstrated its efficiency in improving system effectiveness at no extra cost.

Plug-and -Play Model Architecture and Development Environment for Powertrain/Propulsion System - Final CRADA Report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rousseau, Aymeric

2013-02-01

Several tools already exist to develop detailed plant model, including GT-Power, AMESim, CarSim, and SimScape. The objective of Autonomie is not to provide a language to develop detailed models; rather, Autonomie supports the assembly and use of models from design to simulation to analysis with complete plug-and-play capabilities. Autonomie provides a plug-and-play architecture to support this ideal use of modeling and simulation for math-based automotive control system design. Models in the standard format create building blocks, which are assembled at runtime into a simulation model of a vehicle, system, subsystem, or component to simulate. All parts of the graphical usermore » interface (GUI) are designed to be flexible to support architectures, systems, components, and processes not yet envisioned. This allows the software to be molded to individual uses, so it can grow as requirements and technical knowledge expands. This flexibility also allows for implementation of legacy code, including models, controller code, processes, drive cycles, and post-processing equations. A library of useful and tested models and processes is included as part of the software package to support a full range of simulation and analysis tasks, immediately. Autonomie also includes a configuration and database management front end to facilitate the storage, versioning, and maintenance of all required files, such as the models themselves, the model’s supporting files, test data, and reports. During the duration of the CRADA, Argonne has worked closely with GM to implement and demonstrate each one of their requirements. A use case was developed by GM for every requirement and demonstrated by Argonne. Each of the new features were verified by GM experts through a series of Gate. Once all the requirements were validated they were presented to the directors as part of GM Gate process.« less

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.

From autonomy to creativity: a multilevel investigation of the mediating role of harmonious passion.

Liu, Dong; Chen, Xiao-Ping; Yao, Xin

2011-03-01

Building on self-determination theory, we theorized about and demonstrated, through 2 multilevel field studies, the pivotal role of harmonious passion in translating organizational autonomy support and individual autonomy orientation into job creativity. Results based on 3-level data from 856 members in 111 teams within 23 work units of a porous metal company (Study 1) and from 525 employees in 98 teams of 18 branches of a large commercial bank (Study 2) revealed 2 major findings. First, organizational autonomy support from a higher organizational level (unit or branch) compensated for the effect of autonomy support from a lower organizational level (team) or individual autonomy orientation on employees' harmonious passion. Second, harmonious passion mediated the interactive effects of unit (branch) autonomy support and team member autonomy orientation, of team autonomy support and team member autonomy orientation, and of unit (branch) autonomy support and team autonomy support on individual creativity. We discuss the theoretical and practical implications of these findings in the organizational context. PsycINFO Database Record (c) 2011 APA, all rights reserved.

Orbital Express fluid transfer demonstration system

2008-04-01

Propellant resupply of orbiting spacecraft is no longer in the realm of high risk development. The recently concluded Orbital Express (OE) mission included a fluid transfer demonstration that operated the hardware and control logic in space, bringing the Technology Readiness Level to a solid TRL 7 (demonstration of a system prototype in an operational environment). Orbital Express (funded by the Defense Advanced Research Projects Agency, DARPA) was launched aboard an Atlas-V rocket on March 9th, 2007. The mission had the objective of demonstrating technologies needed for routine servicing of spacecraft, namely autonomous rendezvous and docking, propellant resupply, and orbital replacement unit transfer. The demonstration system used two spacecraft. A servicing vehicle (ASTRO) performed multiple dockings with the client (NextSat) spacecraft, and performed a variety of propellant transfers in addition to exchanges of a battery and computer. The fluid transfer and propulsion system onboard ASTRO, in addition to providing the six degree-of-freedom (6 DOF) thruster system for rendezvous and docking, demonstrated autonomous transfer of monopropellant hydrazine to or from the NextSat spacecraft 15 times while on orbit. The fluid transfer system aboard the NextSat vehicle was designed to simulate a variety of client systems, including both blowdown pressurization and pressure regulated propulsion systems. The fluid transfer demonstrations started with a low level of autonomy, where ground controllers were allowed to review the status of the demonstration at numerous points before authorizing the next steps to be performed. The final transfers were performed at a full autonomy level where the ground authorized the start of a transfer sequence and then monitored data as the transfer proceeded. The major steps of a fluid transfer included the following: mate of the coupling, leak check of the coupling, venting of the coupling, priming of the coupling, fluid transfer, gauging of receiving tank, purging of coupling and de-mate of the coupling.

A mobile version of the NASA/DARPA Robonaut humanoid recently completed initial autonomy trials working directly with humans in cluttered environments. This compact robot combines the upper body of the Robonaut system with a Segway Robotic Mobility Platform yielding a dexterous, maneuverable humanoid ideal for interacting with human co-workers in a range of environments. This system uses stereovision to locate human teammates and tools and a navigation system that uses laser range and vision data to follow humans while avoiding obstacles. Tactile sensors provide information to grasping algorithms for efficient tool exchanges. The autonomous architecture utilizes these pre-programmed skills to form complex behaviors. The initial behavior demonstrates a robust capability to assist a human by acquiring a tool from a remotely located individual and then following the human in a cluttered environment with the tool for future use.

Reconfigurable Autonomy for Future Planetary Rovers

NASA Astrophysics Data System (ADS)

Burroughes, Guy

Extra-terrestrial Planetary rover systems are uniquely remote, placing constraints in regard to communication, environmental uncertainty, and limited physical resources, and requiring a high level of fault tolerance and resistance to hardware degradation. This thesis presents a novel self-reconfiguring autonomous software architecture designed to meet the needs of extraterrestrial planetary environments. At runtime it can safely reconfigure low-level control systems, high-level decisional autonomy systems, and managed software architecture. The architecture can perform automatic Verification and Validation of self-reconfiguration at run-time, and enables a system to be self-optimising, self-protecting, and self-healing. A novel self-monitoring system, which is non-invasive, efficient, tunable, and autonomously deploying, is also presented. The architecture was validated through the use-case of a highly autonomous extra-terrestrial planetary exploration rover. Three major forms of reconfiguration were demonstrated and tested: first, high level adjustment of system internal architecture and goal; second, software module modification; and third, low level alteration of hardware control in response to degradation of hardware and environmental change. The architecture was demonstrated to be robust and effective in a Mars sample return mission use-case testing the operational aspects of a novel, reconfigurable guidance, navigation, and control system for a planetary rover, all operating in concert through a scenario that required reconfiguration of all elements of the system.

Substantial progress has been made recently towards design building and test-flying remotely piloted Micro Air Vehicle's (MAVs). We seek to complement this progress in overcoming the aerodynamic obstacles to.flight at very small scales with a vision stability and autonomy system. The developed system based on a robust horizon detection algorithm which we discuss in greater detail in a companion paper. In this paper, we first motivate the use of computer vision for MAV autonomy arguing that given current sensor technology, vision may he the only practical approach to the problem. We then briefly review our statistical vision-based horizon detection algorithm, which has been demonstrated at 30Hz with over 99.9% correct horizon identification. Next we develop robust schemes for the detection of extreme MAV attitudes, where no horizon is visible, and for the detection of horizon estimation errors, due to external factors such as video transmission noise. Finally, we discuss our feed-back controller for self-stabilized flight, and report results on vision autonomous flights of duration exceeding ten minutes.

No thanks! Autonomous interpersonal style is associated with less experience and valuing of gratitude.

PubMed

Parker, Suzanne C; Majid, Haseeb; Stewart, Kate L; Ahrens, Anthony H

2017-12-01

Gratitude has been promoted as a beneficial emotional experience. However, gratitude is not universally experienced as positive. The current work examines whether an autonomous interpersonal style is associated with differential experience of gratitude. Study 1 found an inverse relationship between trait autonomy and both trait gratitude and positivity of response to receiving a hypothetical benefit from a friend. Study 2 replicated the finding that those higher in autonomy report less trait gratitude, and also demonstrated an inverse relationship between autonomy and valuing gratitude. Study 3 found that those higher in autonomy had more self-image goals and reduced compassionate goals in relationships, and that valuing gratitude mediated the relationship between autonomy and relationship goals. These results show a consistent inverse relationship between autonomy and the experience and valuing of gratitude, suggesting that degree of autonomy is one determinant of whether gratitude is experienced as positive.

A Social Recognition Approach to Autonomy: The Role of Equality-Based Respect.

PubMed

Renger, Daniela; Renger, Sophus; Miché, Marcel; Simon, Bernd

2017-04-01

Inspired by philosophical reasoning about the connection between equality and freedom, we examined whether experiences of (equality-based) respect increase perceived autonomy. This link was tested with generalized experiences of respect and autonomy people make in their daily lives (Study 1) and with more specific experiences of employees at the workplace (Study 2). In both studies, respect strongly and independently contributed to perceived autonomy over and above other forms of social recognition (need-based care and achievement-based social esteem) and further affected (life/work) satisfaction. Study 3 experimentally confirmed the hypothesized causal influence of respect on perceived autonomy and demonstrated that this effect further translates into social cooperation. The respect-cooperation link was simultaneously mediated by perceived autonomy and superordinate collective identification. We discuss how the recognition approach, which differentiates between respect, care, and social esteem, can enrich research on autonomy.

Autonomy and Adolescent Social Functioning: The Moderating Effect of Risk

PubMed Central

McElhaney, Kathleen Boykin; Allen, Joseph P.

2006-01-01

This study examined the moderating effect of risk on the relation between autonomy processes and family and adolescent functioning. The present sample comprised 131 adolescents from either a low-risk or high-risk social context, their mothers, and their peers. Observational ratings of autonomy processes within the mother-adolescent dyad were obtained, along with adolescent reports of the quality of the mother-adolescent relationship, and both adolescent and peer reports of the adolescent’s functioning. Consistent with past research, in low-risk families, behavior undermining autonomy was negatively related to relationship quality, and adolescents’ expressions of autonomy were linked with positive indices of social functioning. In high-risk families, however, undermining of autonomy was positively linked with mother-adolescent relationship quality, and adolescents’ expressions of autonomy were linked with negative indices of social functioning. Results are interpreted as demonstrating the ways in which the developmental task of attaining autonomy in adolescence is systematically altered depending on the level of risk and challenge in the adolescent’s social context.

An implicit assumption behind tenets of self-determination theory is that perceptions of autonomy support are a function of absolute modes of information processing. In this study, we examined whether comparative modes of information processing were implicated in the construction of perceptions of autonomy support. In an experimental study, we demonstrated that participants employed comparative modes of information processing in evaluating receipt of small, but not large, amounts of autonomy support. In addition, we found that social comparison processes influenced a number of outcomes that are empirically related to perceived autonomy support such as sense of autonomy, positive affect, perceived usefulness, and effort. Findings shed new light upon the processes underpinning construction of perceptions related to autonomy support and yield new insights into how to increase the predictive validity of models that use autonomy support as a determinant of motivation and psychological well-being. © 2017 The British Psychological Society.

Background: Resident clinics are thought to catalyze educational milestone achievement through opportunities for progressively autonomous surgical care, but studies are lacking for general plastic surgery resident clinics (PSRCs). We demonstrate the achievement of increased surgical autonomy and continuity of care in a PSRC. Methods: A retrospective review of all patients seen in a PSRC from October 1, 2010, to October 1, 2015, was conducted. Our PSRC is supervised by faculty plastic surgery attendings, though primarily run by chief residents in an accredited independent plastic surgery training program. Surgical autonomy was scored on a 5-point scale based on dictated operative reports. Graduated chief residents were additionally surveyed by anonymous online survey. Results: Thousand one hundred forty-four patients were seen in 3,390 clinic visits. Six hundred fifty-three operations were performed by 23 total residents, including 10 graduating chiefs. Senior resident autonomy averaged 3.5/5 (SD = 1.5), 3.6/5 (SD = 1.5), to 3.8/5 (SD = 1.3) in postgraduate years 6, 7, and 8, respectively. A linear mixed model analysis demonstrated that training level had a significant impact on operative autonomy when comparing postgraduate years 6 and 8 (P = 0.026). Graduated residents’ survey responses (N = 10; 100% response rate) regarded PSRC as valuable for surgical experience (4.1/5), operative autonomy (4.4/5), medical knowledge development (4.7/5), and the practice of Accreditation Council of Graduate Medical Education core competencies (4.3/5). Preoperative or postoperative continuity of care was maintained in 93.5% of cases. Conclusion: The achievement of progressive surgical autonomy may be demonstrated within a PSRC model. PMID:28607848

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 Academicmore » 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.« less

Restoration process of the need for autonomy: the early alarm stage.

PubMed

Radel, Rémi; Pelletier, Luc G; Sarrazin, Philippe; Milyavskaya, Marina

2011-11-01

Autonomy is described by self-determination theory as a basic psychological need, essential for individuals' well-being. While basic needs are generally thought to induce a restorative response when thwarted, evidence for such a process is lacking for autonomy. To date, most evidence indicates that autonomy deprivation leads to disaffection of this need in favor of other motives. A temporal model based on the general adaptation syndrome was adapted to reconcile this seeming contradiction. Specifically, it is hypothesized that an early alarm response aimed at restoring the satisfaction of the need for autonomy should precede the later relinquishment and compensation of this need that would result from a prolonged deprivation. Three studies provide support for this model by showing the existence of the immediate autonomy restorative response. Using a controlling situation to manipulate autonomy deprivation, the authors demonstrate in Experiments 1 and 2 that a controlling context leads to enhanced accessibility and an approach bias for autonomy-related stimuli. Experiment 3 indicates that the urge to restore autonomy can also affect personal judgment, leading individuals to make more independent judgments, exercising a nonreactive form of autonomy. Integration of this model within self-determination theory is discussed.

Development of a non-contextual model for determining the autonomy level of intelligent unmanned systems

Durst, Phillip J.; Gray, Wendell; Trentini, Michael

2013-05-01

A simple, quantitative measure for encapsulating the autonomous capabilities of unmanned systems (UMS) has yet to be established. Current models for measuring a UMS's autonomy level require extensive, operational level testing, and provide a means for assessing the autonomy level for a specific mission/task and operational environment. A more elegant technique for quantifying autonomy using component level testing of the robot platform alone, outside of mission and environment contexts, is desirable. Using a high level framework for UMS architectures, such a model for determining a level of autonomy has been developed. The model uses a combination of developmental and component level testing for each aspect of the UMS architecture to define a non-contextual autonomous potential (NCAP). The NCAP provides an autonomy level, ranging from fully non- autonomous to fully autonomous, in the form of a single numeric parameter describing the UMS's performance capabilities when operating at that level of autonomy.

Autonomous Mission Manager for Rendezvous, Inspection and Mating

To meet cost and safety objectives, space missions that involve proximity operations between two vehicles require a high level of autonomy to successfully complete their missions. The need for autonomy is primarily driven by the need to conduct complex operations outside of communication windows, and the communication time delays inherent in space missions. Autonomy also supports the goals of both NASA and the DOD to make space operations more routine, and lower operational costs by reducing the requirement for ground personnel. NASA and the DoD have several programs underway that require a much higher level of autonomy for space vehicles. NASA's Space Launch Initiative (SLI) program has ambitious goals of reducing costs by a factor or 10 and improving safety by a factor of 100. DARPA has recently begun its Orbital Express to demonstrate key technologies to make satellite servicing routine. The Air Force's XSS-ll program is developing a protoflight demonstration of an autonomous satellite inspector. A common element in space operations for many NASA and DOD missions is the ability to rendezvous, inspect anclJor dock with another spacecraft. For DARPA, this is required to service or refuel military satellites. For the Air Force, this is required to inspect un-cooperative resident space objects. For NASA, this is needed to meet the primary SLI design reference mission of International Space Station re-supply. A common aspect for each of these programs is an Autonomous Mission Manager that provides highly autonomous planning, execution and monitoring of the rendezvous, inspection and docking operations. This paper provides an overview of the Autonomous Mission Manager (AMM) design being incorporated into many of these technology programs. This AMM provides a highly scalable level of autonomous operations, ranging from automatic execution of ground-derived plans to highly autonomous onboard planning to meet ground developed mission goals. The AMM provides the capability to automatically execute the plans and monitor the system performance. In the event of system dispersions or failures the AMM can modify plans or abort to assure overall system safety. This paper describes the design and functionality of Draper's AMM framework, presents concept of operations associated with the use of the AMM, and outlines the relevant features of the flight demonstrations.

Methods for Determining the Level of Autonomy to Design into a Human Spaceflight Vehicle: A Function Specific Approach

Proud, Ryan W.; Hart, Jeremy J.; Mrozinski, Richard B.

2003-01-01

The next-generation human spaceflight vehicle is in a unique position to realize the benefits of more than thirty years of technological advancements since the Space Shuttle was designed. Computer enhancements, the emergence of highly reliable decision-making algorithms, and an emphasis on efficiency make an increased use of autonomous systems highly likely. NASA is in a position to take advantage of these advances and apply them to the human spaceflight environment. One of the key paradigm shifts will be the shift, where appropriate, of monitoring, option development, decision-making, and execution responsibility from humans to an Autonomous Flight Management (AFM) system. As an effort to reduce risk for development of an AFM system, NASA engineers are developing a prototype to prove the utility of previously untested autonomy concepts. This prototype, called SMART (Spacecraft Mission Assessment and Replanning Tool), is a functionally decomposed flight management system with an appropriate level of autonomy for each of its functions. As the development of SMART began, the most important and most often asked question was, How autonomous should an AFM system be? A thorough study of the literature through 2002 surrounding autonomous systems has not yielded a standard method for designing a level of autonomy into either a crewed vehicle or an uncrewed vehicle. The current focus in the literature on defining autonomy is centered on developing IQ tests for built systems. The literature that was analyzed assumes that the goal of all systems is to strive for complete autonomy from human intervention, rather than identifying how autonomous each function within the system should have been. In contrast, the SMART team developed a method for determining the appropriate level of autonomy to be designed into each function within a system. This paper summarizes the development of the Level of Autonomy Assessment Tool and its application to the SMART project.

The role of 'accompagnement' in the end-of-life debate in France: from solidarity to autonomy.

PubMed

Gaille, Marie; Horn, Ruth

2016-12-01

This article traces the way autonomy has become a recognised value in health care in France. In a country that based its social fundamentals on the very idea of solidarity for many years, autonomy has long been considered a foreign 'Anglo-American principle'. Taking the example of the end-of-life debate, the article shows, however, how the use of the French term 'accompagnement' allowed autonomy to be redefined and to be associated with the concept of solidarity. Exploring the arguments used over the past 25 years in professional guidelines, parliamentary reports, ethics committee reports, and legal texts, the authors describe the shift that took place in public and legal discourses on end-of-life care. The analysis demonstrates how the scope of autonomy has been limited by other social values, such as the protection of the dying person, in order to become an accepted social value in its own right. The example of the French end-of-life debate shows that depending on how the concept of autonomy is adapted and applied in a specific context, it can be compatible with the idea of solidarity. Such compatibility has been challenged previously in the international bioethics debate. By demonstrating the possibility of combining autonomy and solidarity, this article makes an important contribution to the international bioethics debate and to the dialogue between countries that are often perceived as significantly different.

Discrepancies in Autonomy and Relatedness Promoting Behaviors of Substance Using Mothers and Their Children: The Effects of a Family Systems Intervention.

Parents' and children's autonomy and relatedness behaviors are associated with a wide range of child outcomes. Yet, little is known about how parents and children's autonomy and relatedness behaviors jointly influence child outcomes. The current study captured this joint influence by exploring the longitudinal trajectory of mother-child discrepancies in autonomy and relatedness behaviors and its association with child problem behaviors. The effects of a family systems intervention on the trajectory of mother-child discrepancies were also examined. The sample included 183 substance using mothers and their children (M age = 11.54 years, SD = 2.55, range 8-16; 48 % females). Both the mother and child completed an assessment at baseline, 6- and 18-month post-baseline. A person-centered analysis identified subgroups varying in mother-child discrepancy patterns in their autonomy and relatedness behaviors. The results also showed that participation in the family systems therapy was associated with decreased mother-child discrepancies, and also a synchronous increase in mother's and child's autonomy and relatedness. Additionally, increased mother-child discrepancies and mother-child dyads showing no change in autonomy and relatedness was associated with higher levels of children's problem behaviors. The findings reveal a dynamic process of mother-child discrepancies in autonomy and relatedness behaviors related to child outcomes. The findings also support the effectiveness of the family systems therapy, and highlight the importance of understanding the complexities in family interactions when explaining children's problem behaviors.

Women's reproductive autonomy: medicalisation and beyond.

PubMed

Purdy, L

2006-05-01

Reproductive autonomy is central to women's welfare both because childbearing takes place in women's bodies and because they are generally expected to take primary responsibility for child rearing. In 2005, the factors that influence their autonomy most strongly are poverty and belief systems that devalue such autonomy. Unfortunately, such autonomy is a low priority for most societies, or is anathema to their belief systems altogether. This situation is doubly sad because women's reproductive autonomy is intrinsically valuable for women and also instrumentally valuable for the welfare of humankind. This paper takes for granted the moral and practical necessity of such autonomy and digs deeper into the question of what such a commitment might entail, focusing on the mid-level policy making that, at least in the US and Canada, plays a significant role in shaping women's options. This paper examines a large teaching hospital's policy on reduction of multifetal pregnancies. The policy permits reduction of triplets to twins, but not twins to a singleton. As there is no morally relevant difference between these two types of reduction, it is evident that inappropriate medicalisation can still limit women's autonomy in undesirable ways.

Respect for autonomy in the healthcare context: observations from a qualitative study of young adults with cerebral palsy.

2013-11-01

Respect for patient autonomy is a cornerstone of contemporary medical ethics and clinical practice. In its different shapes and forms (e.g. being informed, being engaged in discussions and decisions about medical care and being supported in developing healthcare preferences and choices), patient autonomy has been fostered by both paediatric and adult professional societies. The transition from paediatric to adult care creates a complex situation where autonomy for medical decisions shifts to the developing adolescent. More specific challenges to respect for autonomy may be experienced by young adults with cerebral palsy in the transition period where, for example, language and motor impairments may affect communication skills and this may be conflated with cognitive disability. To characterize perspectives towards autonomy in the healthcare context for young adults with cerebral palsy. We carried out semi-structured interviews with 14 young adults (aged 18-25) with cerebral palsy. The audiotaped interviews were transcribed verbatim and analysed using a conventional thematic qualitative content analysis. Participants displayed a range of attitudes towards autonomy, suggesting that the value of autonomy is considered in light of competing values and of context. Testimonials from participants demonstrated that both contextual (e.g. ill-adapted health care, lack of specialized public transport) and relational (e.g. attitudes towards parental involvement in decision making) factors negatively or positively impact autonomy. We observed that there were four key elements interwoven in participants' characterization of autonomy: the coupling of decisional and physical autonomy, the influences of family and society on autonomy, the influence of healthcare professionals on autonomy and the need for preparation for autonomy. © 2012 John Wiley & Sons Ltd.

System Analysis Applied to Autonomy: Application to Human-Rated Lunar/Mars Landers

2006-01-01

System analysis is an essential technical discipline for the modern design of spacecraft and their associated missions. Specifically, system analysis is a powerful aid in identifying and prioritizing the required technologies needed for mission and/or vehicle development efforts. Maturation of intelligent systems technologies, and their incorporation into spacecraft systems, are dictating the development of new analysis tools, and incorporation of such tools into existing system analysis methodologies, in order to fully capture the trade-offs of autonomy on vehicle and mission success. A "system analysis of autonomy" methodology will be outlined and applied to a set of notional human-rated lunar/Mars lander missions toward answering these questions: 1. what is the optimum level of vehicle autonomy and intelligence required? and 2. what are the specific attributes of an autonomous system implementation essential for a given surface lander mission/application in order to maximize mission success? Future human-rated lunar/Mars landers, though nominally under the control of their crew, will, nonetheless, be highly automated systems. These automated systems will range from mission/flight control functions, to vehicle health monitoring and prognostication, to life-support and other "housekeeping" functions. The optimum degree of autonomy afforded to these spacecraft systems/functions has profound implications from an exploration system architecture standpoint.

As part of its Systems Autonomy Demonstration Project (SADP), NASA has recently demonstrated the Thermal Expert System (TEXSYS). Advanced real-time expert system and human interface technology was successfully developed and integrated with conventional controllers of prototype space hardware to provide intelligent fault detection, isolation, and recovery capability. Many specialized skills were required, and responsibility for the various phases of the project therefore spanned multiple NASA centers, internal departments and contractor organizations. The test environment required communication among many types of hardware and software as well as between many people. The integration, testing, and configuration management tools and methodologies which were applied to the TEXSYS project to assure its safe and successful completion are detailed. The project demonstrated that artificial intelligence technology, including model-based reasoning, is capable of the monitoring and control of a large, complex system in real time.

Standby-battery autonomy versus power quality

NASA Astrophysics Data System (ADS)

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.

From Here to Autonomy.

Endsley, Mica R

2017-02-01

As autonomous and semiautonomous systems are developed for automotive, aviation, cyber, robotics and other applications, the ability of human operators to effectively oversee and interact with them when needed poses a significant challenge. An automation conundrum exists in which as more autonomy is added to a system, and its reliability and robustness increase, the lower the situation awareness of human operators and the less likely that they will be able to take over manual control when needed. The human-autonomy systems oversight model integrates several decades of relevant autonomy research on operator situation awareness, out-of-the-loop performance problems, monitoring, and trust, which are all major challenges underlying the automation conundrum. Key design interventions for improving human performance in interacting with autonomous systems are integrated in the model, including human-automation interface features and central automation interaction paradigms comprising levels of automation, adaptive automation, and granularity of control approaches. Recommendations for the design of human-autonomy interfaces are presented and directions for future research discussed.

Respect for Autonomy in Light of Neuropsychiatry.

PubMed

Müller, Sabine

2017-06-01

Bioethics needs an elaborated concept of autonomy based on empirical knowledge about the prerequisites of the capacity of autonomy. Whereas Beauchamp and Childress, and many other bioethicists have discussed social influences on the capacity of autonomy in depth, neurobiological influences have received less attention. A comprehensive concept of autonomy should consider both social and biological factors that can diminish the capacity of autonomy. This article focuses on neurobiological influences that can reduce the capacity of autonomy. The thesis of this article is that the integration of neuropsychiatric knowledge into the concept of autonomy is essential for (1) evaluating demands for harmful medical treatments which might be caused by a brain disease, and (2) deciding on involuntary treatments of patients who suffer from substantial lack of autonomy due to neuropsychiatric disorders. Diametrically opposed to such a comprehensive concept of the capacity of autonomy is the concept of 'liberty of illness'. In Germany, this concept is supported not only by anti-psychiatric groups but also by the Federal Constitutional Court. Several real cases demonstrate how the brain can be 'hijacked' by parasites, antibodies or technical devices. Applying the concept of 'liberty of illness' to persons whose decision-making capacity is severely affected by neuropsychiatric disorders is cynical. These patients neither chose their disease nor would refuse effective treatment if their will was not disturbed by the disease. Respect for autonomy should be understood as the positive obligation to save, support or restore the biological prerequisites of the capacity for autonomous decision-making. © 2017 John Wiley & Sons Ltd.

Our goal was to demonstrate, evaluate, and refine HAT principles. This presentation provides a brief summary of the study and initial findings.

Owning Up to Negative Ingroup Traits: How Personal Autonomy Promotes the Integration of Group Identity.

2017-10-01

Our experiences, attributes, and behaviors are diverse, inconsistent, and often negative. Consequently, our capacity to assimilate divergent experiences-particularly negative aspects-is important to the development of a unified self. Whereas this process of integration has received attention at the level of personal identity, it has not been assessed at the level of group identity. We examined the mechanisms involved in integrating positive and negative ingroup identities, as well as related outcomes. In three experiments, participants (N = 332) high and low in autonomy identified either positive or negative aspects of their ingroup and then indicated the extent to which they integrated the attribute. Those high in personal autonomy integrated both positive and negative identities, whereas those low in autonomy acknowledged only positive identities. Study 2 showed that, regardless of identity valence, those high in autonomy felt satisfied and close with their group. Conversely, those low in autonomy felt less close and more dissatisfied with their group after reflecting on negative identities. Finally, reflecting on a negative identity reduced prejudice, but only for those high in autonomy. Owning up to negative group traits is facilitated by autonomy and demonstrates benefits for ingroup and intergroup processes. © 2016 Wiley Periodicals, Inc.

Trajectories of autonomy development across the adolescent transition in children with spina bifida.

2009-02-01

The current study investigated individual growth in autonomy development across the adolescent transition, comparing the trajectories of children with and without spina bifida. Individual growth curve modeling procedures were utilized to describe the developmental course of autonomy across four waves of data collection, from ages 9 to 15, and to test whether illness status [spina bifida vs. matched comparison group (N = 68 for both groups at Time 1)] would significantly predict individual variability in autonomy development. Potential moderators [child gender, SES, and Peabody Picture Vocabulary Test (PPVT) score] of the association between illness status and autonomy development were also examined. Children with spina bifida demonstrated distinct developmental trajectories, though the nature of the group differences varied by type of autonomy development (emotional vs. behavioral), context (i.e. school vs. family), and reporter. Significant interactions with PPVT score and child gender were found. Overall, children with spina bifida show considerable developmental resiliency, but may lag behind their peers in specific areas of autonomy. Boys with spina bifida, and children with spina bifida who have lower than average levels of verbal intelligence, appear to be at greater risk for exhibiting delays in autonomy development.

Autonomy, Competence and Non-interference.

PubMed

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.

Self-determination vs. family-determination: two incommensurable principles of autonomy: a report from East Asia.

PubMed

Fan, Ruiping

1997-01-01

Most contemporary bioethicists believe that Western bioethical principles, such as the principle of autonomy, are universally binding wherever bioethics is found. According to these bioethicists, these principles may be subject to culturally-conditioned further interpretations for their application in different nations or regions, but an 'abstract content' of each principle remains unchanged, which provides 'an objective basis for moral judgment and international law'. This essay intends to demonstrate that this is not the case. Taking the principle of autonomy as an example, this essay argues that there is no such shared 'abstract content' between the Western bioethical principle of autonomy and the East Asian bioethical principle of autonomy. Other things being equal, the Western principle of autonomy demands self-determination, assumes a subjective conception of the good and promotes the value of individual independence, whilst the East Asian principle of autonomy requires family-determination, presupposes an objective conception of the good and upholds the value of harmonious dependence. They differ from each other in the most general sense and basic moral requirement.

The key actors maintaining elders in functional autonomy in Bobo-Dioulasso (Burkina Faso)

PubMed Central

2014-01-01

Background Globally, a significant increase in functional disability among the elderly is expected in the near future. It is therefore vital to begin considering how Sub-Saharan Africa countries can best start building or strengthening the care and support system for that target population. Study objectives are: 1) identify the key actors of the social system who maintain elders in functional autonomy at home in Bobo-Dioulasso (Burkina Faso) and 2) to describe the functional status of older people living at home. Methods We conducted a longitudinal descriptive study among the elderly aged 60 and above (351). Their functional status was evaluated using the Functional Autonomy Measurement System (SMAF). Data analysis was done using the statistical software package STATA (SE11). Results In Bobo-Dioulasso, 68% of seniors have good functional capacity or a slight incapacity and 32% have moderate to severe incapacities. Older people die before (3%) or during (14%) moderate to severe disabilities. This would mean that the quality of medical and/or social care is not good for maintaining functional autonomy of older people with moderate to severe disabilities. Two main groups of people contribute to maintain elders in functional autonomy: the elderly themselves and their family. Community, private or public structures for maintaining elders in functional autonomy are non-existent. The social system for maintaining elders in functional autonomy is incomplete and failing. In case of functional handicap at home, the elders die. But stakeholders are not conscious of this situation; they believe that this system is good for maintaining elders in functional autonomy. Conclusion It is likely that the absence of formal care and support structure likely shortens the lifespan of severely disabled older people. Stakeholders have not yet looked at this possibility. The stakeholders should seriously think about: 1) how to establish the third level of actors who can fulfill the needs to maintain elders in functional autonomy that are not satisfied by others (family members or the older individuals themselves), and 2) how to reinforce the role of each actor and the collaboration between the different groups of people of this system.

Block, Roger F.

1987-01-01

The Automated Subsystem Control for Life Support Systems (ASCLSS) program has successfully developed and demonstrated a generic approach to the automation and control of space station subsystems. The automation system features a hierarchical and distributed real-time control architecture which places maximum controls authority at the lowest or process control level which enhances system autonomy. The ASCLSS demonstration system pioneered many automation and control concepts currently being considered in the space station data management system (DMS). Heavy emphasis is placed on controls hardware and software commonality implemented in accepted standards. The approach demonstrates successfully the application of real-time process and accountability with the subsystem or process developer. The ASCLSS system completely automates a space station subsystem (air revitalization group of the ASCLSS) which moves the crew/operator into a role of supervisory control authority. The ASCLSS program developed over 50 lessons learned which will aide future space station developers in the area of automation and controls..

To Have Control Over or to Be Free From Others? The Desire for Power Reflects a Need for Autonomy.

PubMed

Lammers, Joris; Stoker, Janka I; Rink, Floor; Galinsky, Adam D

2016-04-01

The current research explores why people desire power and how that desire can be satisfied. We propose that a position of power can be subjectively experienced as conferring influence over others or as offering autonomy from the influence of others. Conversely, a low-power position can be experienced as lacking influence or lacking autonomy. Nine studies show that subjectively experiencing one's power as autonomy predicts the desire for power, whereas the experience of influence over others does not. Furthermore, gaining autonomy quenches the desire for power, but gaining influence does not. The studies demonstrated the primacy of autonomy across both experimental and correlational designs, across measured mediation and manipulated mediator approaches, and across three different continents (Europe, United States, India). Together, these studies offer evidence that people desire power not to be a master over others, but to be master of their own domain, to control their own fate. © 2016 by the Society for Personality and Social Psychology, Inc.

Balancing autonomy and utilization of solar power and battery storage for demand based microgrids

NASA Astrophysics Data System (ADS)

Lawder, Matthew T.; Viswanathan, Vilayanur; Subramanian, Venkat R.

2015-04-01

The growth of intermittent solar power has developed a need for energy storage systems in order to decouple generation and supply of energy. Microgrid (MG) systems comprising of solar arrays with battery energy storage studied in this paper desire high levels of autonomy, seeking to meet desired demand at all times. Large energy storage capacity is required for high levels of autonomy, but much of this expensive capacity goes unused for a majority of the year due to seasonal fluctuations of solar generation. In this paper, a model-based study of MGs comprised of solar generation and battery storage shows the relationship between system autonomy and battery utilization applied to multiple demand cases using a single particle battery model (SPM). The SPM allows for more accurate state-of-charge and utilization estimation of the battery than previous studies of renewably powered systems that have used empirical models. The increased accuracy of battery state estimation produces a better assessment of system performance. Battery utilization will depend on the amount of variation in solar insolation as well as the type of demand required by the MG. Consumers must balance autonomy and desired battery utilization of a system within the needs of their grid.

Autonomous agents are being widely used in many systems, such as ambient assisted-living systems, to perform tasks on behalf of humans. However, these systems usually operate in complex environments that entail uncertain, highly dynamic, or irregular workload. In such environments, autonomous agents tend to make decisions that lead to undesirable outcomes. In this paper, we propose a fuzzy-logic-based adjustable autonomy (FLAA) model to manage the autonomy of multi-agent systems that are operating in complex environments. This model aims to facilitate the autonomy management of agents and help them make competent autonomous decisions. The FLAA model employs fuzzy logic to quantitatively measure and distribute autonomy among several agents based on their performance. We implement and test this model in the Automated Elderly Movements Monitoring (AEMM-Care) system, which uses agents to monitor the daily movement activities of elderly users and perform fall detection and prevention tasks in a complex environment. The test results show that the FLAA model improves the accuracy and performance of these agents in detecting and preventing falls. Copyright © 2018 Elsevier B.V. All rights reserved.

2003-01-01

The Mission Simulation Facility (MSF) supports research in autonomy technology for planetary exploration vehicles. Using HLA (High Level Architecture) across distributed computers, the MSF connects users autonomy algorithms with provided or third-party simulations of robotic vehicles and planetary surface environments, including onboard components and scientific instruments. Simulation fidelity is variable to meet changing needs as autonomy technology advances in Technical Readiness Level (TRL). A virtual robot operating in a virtual environment offers numerous advantages over actual hardware, including availability, simplicity, and risk mitigation. The MSF is in use by researchers at NASA Ames Research Center (ARC) and has demonstrated basic functionality. Continuing work will support the needs of a broader user base.

Nitric Oxide Induces Ca2+-independent Activity of the Ca2+/Calmodulin-dependent Protein Kinase II (CaMKII)*

PubMed Central

Coultrap, Steven J.; Bayer, K. Ulrich

2014-01-01

Both signaling by nitric oxide (NO) and by the Ca2+/calmodulin (CaM)-dependent protein kinase II α isoform (CaMKIIα) are implicated in two opposing forms of synaptic plasticity underlying learning and memory, as well as in excitotoxic/ischemic neuronal cell death. For CaMKIIα, these functions specifically involve also Ca2+-independent autonomous activity, traditionally generated by Thr-286 autophosphorylation. Here, we demonstrate that NO-induced S-nitrosylation of CaMKIIα also directly generated autonomous activity, and that CaMKII inhibition protected from NO-induced neuronal cell death. NO induced S-nitrosylation at Cys-280/289, and mutation of either site abolished autonomy, indicating that simultaneous nitrosylation at both sites was required. Additionally, autonomy was generated only when Ca2+/CaM was present during NO exposure. Thus, generation of this form of CaMKIIα autonomy requires simultaneous signaling by NO and Ca2+. Nitrosylation also significantly reduced subsequent CaMKIIα autophosphorylation specifically at Thr-286, but not at Thr-305. A previously described reduction of CaMKII activity by S-nitrosylation at Cys-6 was also observed here, but only after prolonged (>5 min) exposure to NO donors. These results demonstrate a novel regulation of CaMKII by another second messenger system and indicate its involvement in excitotoxic neuronal cell death. PMID:24855644

Agent autonomy approach to probabilistic physics-of-failure modeling of complex dynamic systems with interacting failure mechanisms

NASA Astrophysics Data System (ADS)

Gromek, Katherine Emily

A novel computational and inference framework of the physics-of-failure (PoF) reliability modeling for complex dynamic systems has been established in this research. The PoF-based reliability models are used to perform a real time simulation of system failure processes, so that the system level reliability modeling would constitute inferences from checking the status of component level reliability at any given time. The "agent autonomy" concept is applied as a solution method for the system-level probabilistic PoF-based (i.e. PPoF-based) modeling. This concept originated from artificial intelligence (AI) as a leading intelligent computational inference in modeling of multi agents systems (MAS). The concept of agent autonomy in the context of reliability modeling was first proposed by M. Azarkhail [1], where a fundamentally new idea of system representation by autonomous intelligent agents for the purpose of reliability modeling was introduced. Contribution of the current work lies in the further development of the agent anatomy concept, particularly the refined agent classification within the scope of the PoF-based system reliability modeling, new approaches to the learning and the autonomy properties of the intelligent agents, and modeling interacting failure mechanisms within the dynamic engineering system. The autonomous property of intelligent agents is defined as agent's ability to self-activate, deactivate or completely redefine their role in the analysis. This property of agents and the ability to model interacting failure mechanisms of the system elements makes the agent autonomy fundamentally different from all existing methods of probabilistic PoF-based reliability modeling. 1.

Flueckiger, Lorenzo; Neukom, Christian

2003-01-01

Autonomy is a key factor in remote robotic exploration and there is significant activity addressing the application of autonomy to remote robots. It has become increasingly important to have simulation tools available to test the autonomy algorithms. While indus1;rial robotics benefits from a variety of high quality simulation tools, researchers developing autonomous software are still dependent primarily on block-world simulations. The Mission Simulation Facility I(MSF) project addresses this shortcoming with a simulation toolkit that will enable developers of autonomous control systems to test their system s performance against a set of integrated, standardized simulations of NASA mission scenarios. MSF provides a distributed architecture that connects the autonomous system to a set of simulated components replacing the robot hardware and its environment.

This research program has successfully demonstrated a new target label architecture that allows a microcomputer to determine the position, orientation, and identity of an object. It contains a CAD-like database with specific geometric information about the object for approach, grasping, and docking maneuvers. Successful demonstrations were performed selecting and docking an ORU box with either of two ORU receptacles. Small, but significant differences were seen in the two camera types used in the program, and camera sensitive program elements have been identified. The software has been formatted into a new co-autonomy system which provides various levels of operator interaction and promises to allow effective application of telerobotic systems while code improvements are continuing.

Health equality, social justice and the poverty of autonomy.

PubMed

Newdick, Christopher

2017-10-01

How does the concept of autonomy assist public responses to 'lifestyle' diseases? Autonomy is fundamental to bioethics, but its emphasis on self-determination and individuality hardly supports public health policies to eat and drink less and take more exercise. Autonomy rejects a 'nanny' state. Yet, the cost of non-communicable diseases is increasing to individuals personally and to public health systems generally. Health care systems are under mounting and unsustainable pressure. What is the proper responsibility of individuals, governments and corporate interests working within a global trading environment? When public health care resources are unlikely to increase, we cannot afford to be so diffident to the cost of avoidable diseases.

Need Satisfaction at Work, Job Strain, and Performance: A Diary Study.

2017-08-24

We performed a daily diary study to examine the mediating role of autonomy need satisfaction and competence need satisfaction in the relationships between job characteristics (i.e., job resources, challenge and hindrance demands) and strain and performance. For 10 consecutive working days, 194 employees reported on their daily job resources, challenge and hindrance demands, task performance, strain level, and satisfaction of the needs for competence and autonomy. Multilevel path modeling demonstrated that the within-person relationships between job resources, challenge and hindrance demands, and strain are mediated by autonomy need satisfaction, but not by competence need satisfaction. However, the relationships between job resources and hindrance demands, and performance are mediated by both competence and autonomy need satisfaction. Our findings show that organizations may benefit from designing jobs that provide employees with the opportunity to satisfy their basic needs for competence and autonomy.

Previous research has demonstrated that autonomy support is one particularly effective means of promoting internalization and fostering well-being. The present study sought to determine if this would also be the case with regards to culture by testing the relation of perceived parental autonomy support to the cultural internalization and well-being of multicultural students. In Study 1, 105 multicultural participants living in Canada were more likely to have fully internalized their host and heritage cultures and to have higher self-reported well-being when they reported that their parents were autonomy supportive. In Study 2, 125 Chinese-Malaysians sojourners were also more likely to have fully internalized their heritage culture and indicated higher well-being when they perceived their parents as autonomy supportive. In both studies, heritage cultural internalization was also associated with higher well-being. Copyright 2007 APA

The Porosity of Autonomy: Social and Biological Constitution of the Patient in Biomedicine.

PubMed

Beever, Jonathan; Morar, Nicolae

2016-01-01

The nature and role of the patient in biomedicine comprise issues central to bioethical inquiry. Given its developmental history grounded firmly in a backlash against 20th-century cases of egregious human subjects abuse, contemporary medical bioethics has come to rely on a fundamental assumption: the unit of care (and the unit of value) is the autonomous self-directing patient. In this article we examine first the structure of the feminist social critique of autonomy. Then we show that a parallel argument can be made against relational autonomy as well, demonstrating how this second concept of autonomy fails to take sufficiently into account an array of biological determinants, particularly those from microbial biology. Finally, in light of this biological critique, we question whether or to what extent any relevant and meaningful view of autonomy can be recovered in the contemporary landscape of bioethics.

Autonomy and relatedness in psychopathology and treatment: a cross-cultural formulation.

PubMed

Sato, T

2001-02-01

A cross-cultural view of psychopathology is proposed, contending that there are two basic systems of self-organization. These two systems of self-organization, labeled autonomy and relatedness, are essential to a person's well-being regardless of the culture or society to which the person belongs. The degree of autonomy and relatedness required to maintain mental health in a specific society is affected by cultural mores. People in collectivistic (primarily non-Western) cultures require high levels of relatedness and moderate levels of autonomy to maintain mental health. People in individualistic (primarily Western) cultures require high levels of autonomy and moderate levels of relatedness to maintain mental health. This view, based on a review of past work in various areas of psychology, is discussed in the context of various forms of psychotherapy existing in individualistic and collectivistic cultures.

Characterize the concordance among faculty and resident perceptions of surgical case complexity, resident technical performance, and autonomy in a diverse sample of general surgery procedures using case-specific evaluations. A prospective study was conducted in which a faculty surgeon and surgical resident independently completed a postoperative assessment examining case complexity, resident operative performance (Milestone assessment) and autonomy (Zwisch model). Pearson correlation coefficients (r) reaching statistical significance (p < 0.05) were further classified as moderate (r ≥ 0.40), strong (r ≥ 0.60), or very strong (r ≥ 0.80). This study was conducted in the General Surgery Residency Program at an academic tertiary care facility (Geisinger Medical Center, Danville, PA). Participants included 6 faculty surgeons, in addition to 5 postgraduate year (PGY) 1, 6 midlevel (PGY 2-3), and 4 chief (PGY 4-5) residents. In total, 75 surgical cases were analyzed. Midlevel residents accounted for the highest number of cases (35, 46.6%). Overall, faculty and resident perceptions of case complexity demonstrated a strong correlation (r = 0.76, p < 0.0001). Technical performance scores were also strongly correlated (r = 0.66, p < 0.0001), whereas perceptions of autonomy demonstrated a moderate correlation (r = 0.56, p < 0.0001). Subgroup analysis revealed very strong correlations among faculty perceptions of case complexity and the perceptions of PGY 1 (r = 0.80, p < 0.0001) and chief residents (r = 0.82, p < 0.0001). All other intergroup correlations were strong with 2 notable exceptions as follows: midlevel and chief residents failed to correlate with faculty perceptions of autonomy and operative performance, respectively. General surgery residents generally demonstrated high correlations with faculty perceptions of case complexity, technical performance, and operative autonomy. This generalized accord supports the use of the Milestone and Zwisch assessments in residency programs. However, discordance among perceptions of midlevel resident autonomy and chief resident operative performance suggests that these trainees may need more direct communication from the faculty.

Analytical and Computational Properties of Distributed Approaches to MDO

NASA Technical Reports Server (NTRS)

Alexandrov, Natalia M.; Lewis, Robert Michael

2000-01-01

Historical evolution of engineering disciplines and the complexity of the MDO problem suggest that disciplinary autonomy is a desirable goal in formulating and solving MDO problems. We examine the notion of disciplinary autonomy and discuss the analytical properties of three approaches to formulating and solving MDO problems that achieve varying degrees of autonomy by distributing the problem along disciplinary lines. Two of the approaches-Optimization by Linear Decomposition and Collaborative Optimization-are based on bi-level optimization and reflect what we call a structural perspective. The third approach, Distributed Analysis Optimization, is a single-level approach that arises from what we call an algorithmic perspective. The main conclusion of the paper is that disciplinary autonomy may come at a price: in the bi-level approaches, the system-level constraints introduced to relax the interdisciplinary coupling and enable disciplinary autonomy can cause analytical and computational difficulties for optimization algorithms. The single-level alternative we discuss affords a more limited degree of autonomy than that of the bi-level approaches, but without the computational difficulties of the bi-level methods. Key Words: Autonomy, bi-level optimization, distributed optimization, multidisciplinary optimization, multilevel optimization, nonlinear programming, problem integration, system synthesis

The purpose of this study was to test a motivational model of the coach-athlete relationship, based on self-determination theory and on the hierarchical model of intrinsic and extrinsic motivation. The sample comprised of 608 athletes (ages of 12-17 years) completed the following measures: interest in athlete's input, praise for autonomous behavior, perceived autonomy, intrinsic motivation, and the intention to be physically active. Structural equation modeling results demonstrated that interest in athletes' input and praise for autonomous behavior predicted perceived autonomy, and perceived autonomy positively predicted intrinsic motivation. Finally, intrinsic motivation predicted the intention to be physically active in the future. The results are discussed in relation to the importance of the climate of autonomy support created by the coach on intrinsic motivation and adherence to sport by adolescent athletes. Further, the results provide information related to the possible objectives of future interventions for the education of coaches, with the goal of providing them with tools and strategies to favor the development of intrinsic motivation among their athletes. In conclusion, the climate of autonomy support created by the coach can predict the autonomy perceived by the athletes which predicts the intrinsic motivation experienced by the athletes, and therefore, their adherence to athletic practice. Key pointsImportance of the climate of autonomy support created by the coach on intrinsic motivation and adherence to sport by adolescent athletes.Interest in athletes' input and praise for autonomous behavior predicted perceived autonomy, and perceived autonomy positively predicted intrinsic motivation.Intrinsic motivation predicted the intention to be physically active in the future.

Rational accountability and rational autonomy in academic practice: An extended case study of the communicative ethic of interdisciplinary science

NASA Astrophysics Data System (ADS)

Robertson, Susan Margaret

The dissertation investigates the interaction of rational accountability and rational autonomy in interdisciplinary science within the lifeworld of the university. It focuses on the cultural, social and motivational forces that university researchers draw on, and develop, to constitute and regulate interdisciplinary science. Findings are analyzed within an applied critical social theory framework that attends to the interaction of instrumental and communicative rational action within the public spaces that constitute the lifeworld of the university as a public sphere in society. The research raises questions of how academics practice interdisciplinary science and how these practices relate to the reproduction of the regulative ideal of the university as a community that practices public reason. The conceptual framework informing the research is Habermas' (1984) theory of communicative action. Using Burawoy's (1991) extended case study method as an operational strategy, two modes of constituting and regulating interdisciplinary science were found. Instrumental rational modes dominated in social contexts of interdisciplinary science where consensus on the normative goals and purposes of rational academic action were pre-existing and pre-supposed by participants. Communicative rational modes dominated in social contexts of interdisciplinary science where the normative goals and purposes of rational academic action entered a contested domain. Endorsements for interdisciplinary science policies are coinciding with demands for increased accountability and relevance of Canada's university system. At the same time that the university system must respond to external demands, it must reproduce itself as a public institution open to the discursive redemption of factual and normative validity claims. The study found that academics participate in, but also contest the instrumental regulation of academic inquiry and conduct by using their constitutional autonomy and freedom to hold others accountable and demonstrate a rational disposition to realize mutual understanding on factual and normative validity claims. By demonstrating a rational disposition to practice autonomy and freedom in realizing mutual understanding on contested validity claims within the lifeworld of the university, public intellectuals realize a capacity for extending the regulative ideal of practicing public reason within the university into the constitution and regulation of public spaces for practicing public reason in the lifeworld of society.

The Systems Autonomy Demonstration Project (SADP) produced a knowledge-based real-time control system for control and fault detection, isolation, and recovery (FDIR) of a prototype two-phase Space Station Freedom external active thermal control system (EATCS). The Thermal Expert System (TEXSYS) was demonstrated in recent tests to be capable of reliable fault anticipation and detection, as well as ordinary control of the thermal bus. Performance requirements were addressed by adopting a hierarchical symbolic control approach-layering model-based expert system software on a conventional, numerical data acquisition and control system. The model-based reasoning capabilities of TEXSYS were shown to be advantageous over typical rule-based expert systems, particularly for detection of unforeseen faults and sensor failures. Volume 1 gives a project overview and testing highlights. Volume 2 provides detail on the EATCS test bed, test operations, and online test results. Appendix A is a test archive, while Appendix B is a compendium of design and user manuals for the TEXSYS software.

Beer, Jenay M; Fisk, Arthur D; Rogers, Wendy A

2014-07-01

A critical construct related to human-robot interaction (HRI) is autonomy, which varies widely across robot platforms. Levels of robot autonomy (LORA), ranging from teleoperation to fully autonomous systems, influence the way in which humans and robots may interact with one another. Thus, there is a need to understand HRI by identifying variables that influence - and are influenced by - robot autonomy. Our overarching goal is to develop a framework for levels of robot autonomy in HRI. To reach this goal, the framework draws links between HRI and human-automation interaction, a field with a long history of studying and understanding human-related variables. The construct of autonomy is reviewed and redefined within the context of HRI. Additionally, the framework proposes a process for determining a robot's autonomy level, by categorizing autonomy along a 10-point taxonomy. The framework is intended to be treated as guidelines to determine autonomy, categorize the LORA along a qualitative taxonomy, and consider which HRI variables (e.g., acceptance, situation awareness, reliability) may be influenced by the LORA.

The graduate medical education system is tasked with training competent and autonomous health care providers while also improving patient safety, delivering more efficient care, and cutting costs. Concerns about resident autonomy and preparation for independent and safe practice appear to be growing, and the field of surgery faces unique challenges in preparing graduates for independent practice. Multiple factors are contributing to an erosion of resident autonomy and decreased operative experience, including differing views of autonomy, financial forces, duty hours regulations, and diverse community health care needs. Identifying these barriers and developing solutions to overcome them are vital first steps in reversing the trend of diminishing autonomy in surgical residency training. This Commentary highlights the problem of decreasing autonomy, outlines specific threats to resident autonomy, and discusses potential solutions to mitigate their impact on the successful transition to independent practice.

The benefits of autonomy support with the general population have been demonstrated numerous times. However, little research has been conducted to verify if these benefits apply to people with special needs. The goal of the study was to examine whether autonomy support (AS) can foster the sense of autonomy of people with a mild intellectual disabilities (MIDs) and improve their experience while engaging in an important but unpleasant learning activity. This experiment compares the effects of two contexts: with and without AS. All participants (N = 51) had a mild intellectual disability and were recruited from rehabilitation centres. Compared to participants in the control group, participants in the AS group tended to experience greater autonomy satisfaction and tended to perceive more value to the activity. They were also significantly more engaged in it, and they experienced a steeper decrease in anxiety over time. This study suggests that the benefits of AS extend to individuals with mild intellectual disability. © 2016 John Wiley & Sons Ltd.

A cybernetic theory of morality and moral autonomy.

PubMed

Chambers, J

2001-04-01

Human morality may be thought of as a negative feedback control system in which moral rules are reference values, and moral disapproval, blame, and punishment are forms of negative feedback given for violations of the moral rules. In such a system, if moral agents held each other accountable, moral norms would be enforced effectively. However, even a properly functioning social negative feedback system could not explain acts in which individual agents uphold moral rules in the face of contrary social pressure. Dr. Frances Kelsey, who withheld FDA approval for thalidomide against intense social pressure, is an example of the degree of individual moral autonomy possible in a hostile environment. Such extreme moral autonomy is possible only if there is internal, psychological negative feedback, in addition to external, social feedback. Such a cybernetic model of morality and moral autonomy is consistent with certain aspects of classical ethical theories.

Still-Born Autonomy Insurance Plan in Quebec: An Example of a Public Long-Term Care Insurance System in Canada.

Hébert, Réjean

2016-01-01

Funding long-term care (LTC) is a challenge under the existing Beveridgean universal healthcare system. The Autonomy Insurance (AI) plan developed in Quebec was an attempt to introduce public LTC insurance into our healthcare system. The AI benefit was based on an assessment of the needs of older people and those with disabilities using a disability scale (SMAF) and case-mix classification system (Iso-SMAF Profiles). Under the plan, the benefit would be used to fund public institutions or purchase services from private organizations. Case managers were responsible for assessments and helping users and their families plan services and decide how to use the AI benefit. Funding AI was based on general tax revenues without capitalized funding, under a separate protected budget program. Projections were made for the additional budget needed to support AI, which would have mitigated the forecast increase in LTC spending due to population aging. All the legal, administrative, funding, training and contractual issues were dealt with, for implementation of the plan in April 2015. Unfortunately, the project was still-born for political reasons, but it demonstrates the feasibility of this essential innovation for Canada.

The PROBA2 Science Centre (P2SC) is a small-scale science operations centre supporting the Sun observation instruments onboard PROBA2: the EUV imager Sun Watcher using APS detectors and image Processing (SWAP) and Large-Yield Radiometer (LYRA). PROBA2 is one of ESA's small, low-cost Projects for Onboard Autonomy (PROBA) and part of ESA's In-Orbit Technology Demonstration Programme. The P2SC is hosted at the Royal Observatory of Belgium, co-located with both Principal Investigator teams. The P2SC tasks cover science planning, instrument commanding, instrument monitoring, data processing, support of outreach activities, and distribution of science data products. PROBA missions aim for a high degree of autonomy at mission and system level, including the science operations centre. The autonomy and flexibility of the P2SC is reached by a set of web-based interfaces allowing the operators as well as the instrument teams to monitor quasi-continuously the status of the operations, allowing a quick reaction to solar events. In addition, several new concepts are implemented at instrument, spacecraft, and ground-segment levels allowing a high degree of flexibility in the operations of the instruments. This article explains the key concepts of the P2SC, emphasising the automation and the flexibility achieved in the commanding as well as the data-processing chain.

Impacts of autonomy-supportive versus controlling instructional language on motor learning.

Hooyman, Andrew; Wulf, Gabriele; Lewthwaite, Rebecca

2014-08-01

The authors examined the influence of autonomy-supportive (ASL), controlling (CL), and neutral instructional language (NL) on motor skill learning (cricket bowling action). Prior to and several times during the practice phase, participants watched the same video demonstration of the bowling action but with different voice-over instructions. The instructions were designed to provide the same technical information but to vary in terms of the degree of choice performers would perceive when executing the task. In addition to measurements of throwing accuracy (i.e., deviation from the target), perceived choice, self-efficacy, and positive and negative affect were assessed at the end of the practice phase and after a retention test without demonstrations and instructions on Day 2. ASL resulted in perceptions of greater choice, higher self-efficacy, and more positive affect during practice than CL, and enhanced learning as demonstrated by retention test performance. Thus, granting learners autonomy appeared to endow them with confidence in their ability, diminished needs for control of negative emotional responses, and created more positive affect, which may help consolidate motor memories.

Capturing Requirements for Autonomous Spacecraft with Autonomy Requirements Engineering

NASA Astrophysics Data System (ADS)

Vassev, Emil; Hinchey, Mike

2014-08-01

The Autonomy Requirements Engineering (ARE) approach has been developed by Lero - the Irish Software Engineering Research Center within the mandate of a joint project with ESA, the European Space Agency. The approach is intended to help engineers develop missions for unmanned exploration, often with limited or no human control. Such robotics space missions rely on the most recent advances in automation and robotic technologies where autonomy and autonomic computing principles drive the design and implementation of unmanned spacecraft [1]. To tackle the integration and promotion of autonomy in software-intensive systems, ARE combines generic autonomy requirements (GAR) with goal-oriented requirements engineering (GORE). Using this approach, software engineers can determine what autonomic features to develop for a particular system (e.g., a space mission) as well as what artifacts that process might generate (e.g., goals models, requirements specification, etc.). The inputs required by this approach are the mission goals and the domain-specific GAR reflecting specifics of the mission class (e.g., interplanetary missions).

Distributive justice, procedural justice, and psychological distress: the moderating effect of coworker support and work autonomy.

PubMed

Rousseau, Vincent; Salek, Salwa; Aubé, Caroline; Morin, Estelle M

2009-07-01

Recent research has demonstrated that the perception of injustice at work may increase psychological health-related problems. The purpose of this study is to examine the moderating effect of coworker support and work autonomy on the relationships between both distributive and procedural justice and psychological distress. Results, on the basis of responses to questionnaires given to 248 prison employees, show that coworker support moderates the relationships between both forms of justice and psychological distress. Specifically, these relationships are weakened when employees benefit from a high level of coworker support. Furthermore, work autonomy moderates the relationship between procedural justice and psychological distress but not the relationship between distributive justice and psychological distress. Thus, procedural injustice is less likely to increase psychological distress when the level of work autonomy is high. (c) 2009 APA, all rights reserved.

Invited Article: Threats to physician autonomy in a performance-based reimbursement system.

PubMed

Larriviere, Daniel G; Bernat, James L

2008-06-10

Physician autonomy is currently threatened by the external application of pay for performance standards and required conformity to practice guidelines. This phenomenon is being driven by concerns over the economic viability of increasing per capita health care expenditures without a concomitant rise in favorable health outcomes and by the unjustified marked variations among physicians' practice patterns. Proponents contend that altering the reimbursement system to encourage physicians to make choices based upon the best available evidence would be one way to ensure better outcomes per health care dollar spent. Although physician autonomy is most easily justified when decisions are made by appealing to the best available evidence, incentivizing decision-making risks sacrificing physician autonomy to political and social forces if the limitations of evidence-based medicine are not respected. Any reimbursement system designed to encourage physicians to utilize the best available evidence by providing financial incentives must recognize physicians who try to play to the numbers as well as physicians who refuse to follow the best available evidence if doing so would conflict with good medicine or patient preferences. By designing, promulgating, and updating evidence-based clinical practice guidelines, medical specialty societies can limit threats to physician autonomy while improving medical practice.

Understanding critical care nurses' autonomy in Jordan.

PubMed

Maharmeh, Mahmoud

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.

[Ethical aspects of resuscitation].

Elo, Gábor; Dobos, Márta; Zubek, László

2006-07-09

The former typically paternalistic physician-patient relationship has changed gradually toward an autonomy based one in the second half of the 20th century. Patient's autonomy includes the right to refuse life-saving therapy in modern constitutional states. Hungarian law assures the right to refuse life-saving treatment as well. However to our knowledge no such therapy refusal has occurred since the law coming into force likely because of the rather strict regulations. Forgoing resuscitation is basically determined by two factors: autonomy of the patient, and medical futility. The alteration of the law's form can facilitate the lawful Do Not Resuscitate (DNR)orders for the sake of patient's autonomy. Qualitative futility is characterized by quality of life, which only the patient has the right to judge. Resuscitation protocols based on results of controlled studies can significantly improve both the success rate of resuscitations and the quality of life. Education plays a prominent role in this process as it was demonstrated in our prospective comparative study. According to author's study Hungarian DNR orders are paternalistic and patient autonomy plays a secondary role. It was also established that patient's autonomy significantly improved in the subgroup trained according to international standards. Hungarian results were compared to the results of a highly educated group in the second study. The results confirmed the presumption: the education of resuscitation according to international standards improves both the representation of patient's autonomy in DNR decisions, survival rate and quality of life.

An assigned responsibility system for robotic teleoperation control.

PubMed

Small, Nicolas; Lee, Kevin; Mann, Graham

2018-01-01

This paper proposes an architecture that explores a gap in the spectrum of existing strategies for robot control mode switching in adjustable autonomy. In situations where the environment is reasonably known and/or predictable, pre-planning these control changes could relieve robot operators of the additional task of deciding when and how to switch. Such a strategy provides a clear division of labour between the automation and the human operator(s) before the job even begins, allowing for individual responsibilities to be known ahead of time, limiting confusion and allowing rest breaks to be planned. Assigned Responsibility is a new form of adjustable autonomy-based teleoperation that allows the selective inclusion of automated control elements at key stages of a robot operation plan's execution. Progression through these stages is controlled by automatic goal accomplishment tracking. An implementation is evaluated through engineering tests and a usability study, demonstrating the viability of this approach and offering insight into its potential applications.

"I Can't Eat if I Don't Plass": Impoverished Plasma Donors, Alternatives, and Autonomy.

PubMed

Weimer, Steven

2015-12-01

One of the central considerations to be taken into account in evaluating the ethics of compensation for donated plasma is respect for donor autonomy. And one of the main arguments against compensated donation systems is that many donors do or would come from circumstances of poverty that restrict their alternatives in a way that compromises those donors' autonomy. In this paper, I develop and defend a novel version of this "compromised autonomy argument" which improves upon extant versions by employing a more nuanced account of the relationship between alternatives and autonomy. According to the version of that argument I offer, donors lack autonomy with respect to the sale of their plasma if their economic circumstances leave them with no choice but to sell their plasma (i.e., "plass") on the basis of a desire they have had no choice but to hold. After explicating the key terms of this argument, I examine its policy implications. I argue that, given several reasonable empirical assumptions, my argument implies that a majority of individuals whose income falls below a specified threshold would indeed lack autonomy with respect to the sale of their plasma. Most individuals whose income falls above that threshold, on the other hand, would be able to autonomously sell their plasma. I argue that respect for donor autonomy therefore speaks in favor of an income-restricted system of compensated donation which permits collection centers to purchase plasma from those whose income falls above the relevant threshold, but not those below it.

The growth of intermittent solar power has developed a need for energy storage systems in order to decouple generation and supply of energy. Microgrid (MG) systems comprising of solar arrays with battery energy storage studied in this paper desire high levels of autonomy, seeking to meet desired demand at all times. Large energy storage capacity is required for high levels of autonomy, but much of this expensive capacity goes unused for a majority of the year due to seasonal fluctuations of solar generation. In this paper, a model-based study of MGs comprised of solar generation and battery storage shows themore » relationship between system autonomy and battery utilization applied to multiple demand cases using a single particle battery model (SPM). The SPM allows for more accurate state-of-charge and utilization estimation of the battery than previous studies of renewably powered systems that have used empirical models. The increased accuracy of battery state estimation produces a better assessment of system performance. Battery utilization will depend on the amount of variation in solar insolation as well as the type of demand required by the MG. Consumers must balance autonomy and desired battery utilization of a system within the needs of their grid.« less

Medical education and the ACGME duty hour requirements: assessing the effect of a day float system on educational activities.

PubMed

Roey, Steve

2006-01-01

In July 2003, the Accreditation Council for Graduate Medical Education (ACGME) instituted new resident work hour mandates, which are being shown to improve resident well-being and patient safety. However, there are limited data on the impact these new mandates may have on educational activities. To assess the impact on educational activities of a day float system created to meet ACGME work hour mandates. The inpatient ward coverage was changed by adding a day float team responsible for new patient admissions in the morning, with the on-call teams starting later and being responsible for new patient admissions thereafter. I surveyed the residents to assess the impact of this new system on educational activities-resident autonomy, attending teaching, conference attendance, resident teaching, self-directed learning, and ability to complete patient care responsibilities. There was no adverse effect of the day float system on educational activities. House staff reported increased autonomy, enhanced teaching from attending physicians, and improved ability to complete patient care responsibilities. Additionally, house staff demonstrated improved compliance with the ACGME mandates. The implementation of a novel day float system for the inpatient medicine ward service improved compliance with ACGME work duty requirements and did not adversely impact educational activities of the residency training program.

Market liberalism in health care: a dysfunctional view of respecting "consumer" autonomy.

PubMed

Kekewich, Michael A

2014-03-01

The unfortunately vast history of paternalism in both medicine and clinical research has resulted in perpetually increasing respect for patient autonomy and free choice in Western health care systems. Beginning with the negative right to informed consent, the principle of respect for autonomy has for many patients evolved into a positive right to request treatments and expect accommodation. This evolution of patient autonomy has mirrored a more general social attitude of market liberalism where increasing numbers of patients have come to embody the role of the "consumer." This paper explores this transformation and critiques the current way in which respect for patient autonomy is put into practice. Ultimately, this paper concludes that the consumer view of patient autonomy is dysfunctional. Moreover, this paper argues that, based on the inherent goals of medicine, some form of paternalism is required in any meaningfully therapeutic relationship.

The impact of choice on retributive reactions: how observers' autonomy concerns shape responses to criminal offenders.

van Prooijen, Jan-Willem; Kerpershoek, Emiel F P

2013-06-01

The present research examined the psychological origins of retributive reactions, which are defined as independent observers' anger-based emotions, demonized perceptions, and punishment intentions in response to criminal offenders. Based on the idea that society's justice system has an autonomy-protective function, we reason that chronic autonomy interacts with situational autonomy cues (i.e., opportunities to make choices) to predict retributive reactions to criminal offenders. More specifically, we hypothesized that choice opportunities in an unrelated decision-making context would prompt people to display stronger retributive reactions to offenders than no-choice opportunities, and that these effects of choice would be particularly pronounced among people who chronically experience deprivation of autonomy needs. Results from two experiments supported this hypothesis. It is concluded that retributive reactions to criminal offenders originate from a desire to regulate basic autonomy needs. © 2011 The British Psychological Society.

NASA Technical Reports Server (NTRS)

Ashworth, Barry R.

1990-01-01

It is pointed out that when autonomous operations are mixed with those of a manual nature, concepts concerning the boundary of operations and responsibility become clouded. The space station module power management and distribution (SSM/PMAD) automation testbed has the need for such mixed-mode capabilities. The concept of managing the SSM/PMAD testbed in the presence of changing levels of autonomy is examined. A knowledge-based approach to implementing autonomy management in the distributed SSM/PMAD utilizing a centralized planning system is presented. Its knowledge relations and system-wide interactions are discussed, along with the operational nature of the currently functioning SSM/PMAD knowledge-based systems.

How causal analysis can reveal autonomy in models of biological systems

NASA Astrophysics Data System (ADS)

Marshall, William; Kim, Hyunju; Walker, Sara I.; Tononi, Giulio; Albantakis, Larissa

2017-11-01

Standard techniques for studying biological systems largely focus on their dynamical or, more recently, their informational properties, usually taking either a reductionist or holistic perspective. Yet, studying only individual system elements or the dynamics of the system as a whole disregards the organizational structure of the system-whether there are subsets of elements with joint causes or effects, and whether the system is strongly integrated or composed of several loosely interacting components. Integrated information theory offers a theoretical framework to (1) investigate the compositional cause-effect structure of a system and to (2) identify causal borders of highly integrated elements comprising local maxima of intrinsic cause-effect power. Here we apply this comprehensive causal analysis to a Boolean network model of the fission yeast (Schizosaccharomyces pombe) cell cycle. We demonstrate that this biological model features a non-trivial causal architecture, whose discovery may provide insights about the real cell cycle that could not be gained from holistic or reductionist approaches. We also show how some specific properties of this underlying causal architecture relate to the biological notion of autonomy. Ultimately, we suggest that analysing the causal organization of a system, including key features like intrinsic control and stable causal borders, should prove relevant for distinguishing life from non-life, and thus could also illuminate the origin of life problem. This article is part of the themed issue 'Reconceptualizing the origins of life'.

2015-02-01

Understanding the relationship between women's political participation and health has eluded researchers and cannot be adequately studied using traditional epidemiological or social scientific methodologies. We employed a health capability framework to understand dimensions of health agency to illuminate how local political economies affect health. Exploiting a cluster-randomized controlled trial of a community-based behavior change management intervention in northern India, we conducted a qualitative study with semistructured, in-depth focus groups in both intervention and nonintervention villages. We presented scenarios to each group regarding the limitations and motivations involved in women's political participation and health. Thematic analysis focused on four domains of health agency -- participation, autonomy, self-efficacy, and health systems -- relevant for understanding the relationship between political participation and health. Elder women demonstrated the greatest sense of self-efficacy and as a group cited the largest number of successful health advocacy efforts. Participation in an associated community-based neonatal intervention had varying effects, showing some differences in self-efficacy, but only rare improvements in participation, autonomy, or health system functioning. Better understanding of cultural norms surrounding autonomy, the local infrastructure and health system, and male and female perceptions of political participation and self-efficacy are needed to improve women's health agency. For a community-based participatory health intervention to improve health capability effectively, explicit strategies focused on health agency should be as central as health indicators.

Mission Operations with an Autonomous Agent

NASA Technical Reports Server (NTRS)

Pell, Barney; Sawyer, Scott R.; Muscettola, Nicola; Smith, Benjamin; Bernard, Douglas E.

1998-01-01

The Remote Agent (RA) is an Artificial Intelligence (AI) system which automates some of the tasks normally reserved for human mission operators and performs these tasks autonomously on-board the spacecraft. These tasks include activity generation, sequencing, spacecraft analysis, and failure recovery. The RA will be demonstrated as a flight experiment on Deep Space One (DSI), the first deep space mission of the NASA's New Millennium Program (NMP). As we moved from prototyping into actual flight code development and teamed with ground operators, we made several major extensions to the RA architecture to address the broader operational context in which PA would be used. These extensions support ground operators and the RA sharing a long-range mission profile with facilities for asynchronous ground updates; support ground operators monitoring and commanding the spacecraft at multiple levels of detail simultaneously; and enable ground operators to provide additional knowledge to the RA, such as parameter updates, model updates, and diagnostic information, without interfering with the activities of the RA or leaving the system in an inconsistent state. The resulting architecture supports incremental autonomy, in which a basic agent can be delivered early and then used in an increasingly autonomous manner over the lifetime of the mission. It also supports variable autonomy, as it enables ground operators to benefit from autonomy when L'@ey want it, but does not inhibit them from obtaining a detailed understanding and exercising tighter control when necessary. These issues are critical to the successful development and operation of autonomous spacecraft.

A demonstration implementation of a distributed data processing hospital information system using an intelligent local area communications network (LACN) technology is described. This system is operational at the UCSF Medical Center and integrates four heterogeneous, stand-alone minicomputers. The applications systems are PID/Registration, Outpatient Pharmacy, Clinical Laboratory and Radiology/Medical Records. Functional autonomy of these systems has been maintained, and no operating system changes have been required. The LACN uses a fiber-optic communications medium and provides extensive communications protocol support within the network, based on the ISO/OSI Model. The architecture is reconfigurable and expandable. This paper describes system architectural issues, the applications environment and the local area network.

Maintaining wild places increasingly involves intensive human interventions. Several recent projects use semi-automated mediating technologies to enact conservation and restoration actions, including re-seeding and invasive species eradication. Could a deep-learning system sustain the autonomy of nonhuman ecological processes at designated sites without direct human interventions? We explore here the prospects for automated curation of wild places, as well as the technical and ethical questions that such co-creation poses for ecologists, conservationists, and designers. Our goal is to foster innovative approaches to creating and maintaining the autonomy of evolving ecological systems. Copyright © 2016 Elsevier Ltd. All rights reserved.

Remotely Piloted Aircraft Systems Panel (RPASP) Working Paper: Autonomy and Automation

Shively, Jay

2017-01-01

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 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 a definition of "automation". We recommend that autonomy and autonomous operations are out of the scope of the RPAS panel. WG7 proposes to develop, in consultation with other workgroups, a taxonomy of "Levels of Automation" for RPAS.

Do Children's Executive Functions Account for Associations Between Early Autonomy-Supportive Parenting and Achievement Through High School?

Bindman, Samantha W.; Pomerantz, Eva M.; Roisman, Glenn I.

2015-01-01

This study evaluated whether the positive association between early autonomy-supportive parenting and children's subsequent achievement is mediated by children's executive functions. Using observations of mothers’ parenting from the NICHD Study of Early Child Care and Youth Development (N = 1,306), analyses revealed that mothers’ autonomy support over the first 3 years of life predicted enhanced executive functions (i.e., inhibition, delay of gratification, and sustained attention) during the year prior to kindergarten and academic achievement in elementary and high school even when mothers’ warmth and cognitive stimulation, as well as other factors (e.g., children's early general cognitive skills and mothers’ educational attainment) were covaried. Mediation analyses demonstrated that over and above other attributes (e.g., temperament), children's executive functions partially accounted for the association between early autonomy-supportive parenting and children's subsequent achievement.

2011-04-01

Within the self-determination theory (Deci & Ryan, 2000) framework, research has considered the consequences of coaches' autonomy supportive and controlling behaviors on various athlete outcomes (e.g., motivation and performance). The antecedents of such behaviors, however, have received little attention. Coaches (N = 443) from a variety of sports and competitive levels completed a self-report questionnaire to assess their psychological need satisfaction, well-being and perceived interpersonal behaviors toward their athletes. Structural equation modeling demonstrated that coaches' competence and autonomy need satisfaction positively predicted their levels of psychological well-being, as indexed by positive affect and subjective vitality. In turn, coaches' psychological well-being positively predicted their perceived autonomy support toward their athletes, and negatively predicted their perceived controlling behaviors. Overall, the results highlight the importance of coaching contexts that facilitate coaches' psychological need satisfaction and well-being, thereby increasing the likelihood of adaptive coach interpersonal behavior toward athletes.

Ageism within the context of care has attracted increasing attention in recent years. Similarly, autonomy has developed into a prominent concept within health care law and ethics. This paper explores the way that ageism, understood as a set of negative attitudes about old age or older people, may impact on an older person's ability to make maximally autonomous decisions within health care. In particular, by appealing to feminist constructions of autonomy as relational, I will argue that the key to establishing this link is the concept of self-relations such as self-trust, self-worth and self-esteem. This paper aims to demonstrate how these may be impacted by the internalisation of negative attitudes associated with old age and care. In light of this, any legal or policy response must be sensitive to and flexible enough to deal with the way in which ageism impacts autonomy.

This study evaluated whether the positive association between early autonomy-supportive parenting and children's subsequent achievement is mediated by children's executive functions. Using observations of mothers' parenting from the NICHD Study of Early Child Care and Youth Development ( N = 1,306), analyses revealed that mothers' autonomy support over the first 3 years of life predicted enhanced executive functions (i.e., inhibition, delay of gratification, and sustained attention) during the year prior to kindergarten and academic achievement in elementary and high school even when mothers' warmth and cognitive stimulation, as well as other factors (e.g., children's early general cognitive skills and mothers' educational attainment) were covaried. Mediation analyses demonstrated that over and above other attributes (e.g., temperament), children's executive functions partially accounted for the association between early autonomy-supportive parenting and children's subsequent achievement.

In this paper, we will describe the evolution of the software from prototype to full time operation onboard Earth Observing One (EO-1). We will quantify the increase in science, decrease in operations cost, and streamlining of operations procedures. Included will be a description of how this software was adapted post-launch to the EO-1 mission, which had very limited computing resources which constrained the autonomy flight software. We will discuss ongoing deployments of this software to the Mars Exploration Rovers and Mars Odyssey Missions as well as a discussion of lessons learned during this project. Finally, we will discuss how the onboard autonomy has been used in conjunction with other satellites and ground sensors to form an autonomous sensor-web to study volcanoes, floods, sea-ice topography, and wild fires. As demonstrated on EO-1, onboard autonomy is a revolutionary advance that will change the operations approach on future NASA missions...

Teacher autonomy support reduces adolescent anxiety and depression: An 18-month longitudinal study.

Grounded in stage-environment fit theory, this study adopts a longitudinal design to examine the contribution of autonomy support from teachers to reducing adolescent anxiety and depression. A total of 236 Chinese adolescents (57.38% females, Mage = 14.34) completed questionnaires on teacher autonomy support, basic psychological needs satisfaction, school engagement, anxiety, and depression in the fall and spring semesters of their 7th and 8th grade years. The results showed that teacher autonomy support in the fall of 7th grade boosted basic psychological needs satisfaction in the spring of 7th grade; this, in turn, increased school engagement in the fall of 8th grade, which subsequently decreased anxiety and depression in the spring of 8th grade. These findings demonstrated the significant effect of teacher autonomy support on reducing adolescent anxiety and depression; furthermore, it highlighted the mediating roles of basic psychological needs satisfaction and school engagement in this relationship.

Ballin, Mark; Holbrook, Jon; Sharma, Shivanjli

2016-01-01

In collaboration with the external community and other government agencies, NASA will develop enabling technologies, standards, and design guidelines to support cost-effective applications of automation and limited autonomy for individual components of aviation systems. NASA will also provide foundational knowledge and methods to support the next epoch. Research will address issues of verification and validation, operational evaluation, national policy, and societal cost-benefit. Two research and development approaches to aviation autonomy will advance in parallel. The Increasing Autonomy (IA) approach will seek to advance knowledge and technology through incremental increases in machine-based support of existing human-centered tasks, leading to long-term reallocation of functions between humans and machines. The Autonomy as a New Technology (ANT) approach seeks advances by developing technology to achieve goals that are not currently possible using human-centered concepts of operation. IA applications are mission-enhancing, and their selection will be based on benefits achievable relative to existing operations. ANT applications are mission-enabling, and their value will be assessed based on societal benefit resulting from a new capability. The expected demand for small autonomous unmanned aircraft systems (UAS) provides an opportunity for development of ANT applications. Supervisory autonomy may be implemented as an expansion of the number of functions or systems that may be controlled by an individual human operator. Convergent technology approaches, such as the use of electronic flight bags and existing network servers, will be leveraged to the maximum extent possible.

An increasing number of countries are exploring the introduction or expansion of autonomous hospitals as one of the numerous health reforms they are introducing to their health system. Hospital autonomy is one of the forms of decentralization that is focused on a specific institution rather than on a political unit. It has gained much interest because it is an attempt to amalgamate the best elements of the public and private sectors in how a hospital is governed, managed and financed. This paper reviews the key elements of the concept of hospital autonomy, the reasons for its expanded use in many countries and a specific example of making a major teaching hospital autonomous in Kenya. A review of the successful experience of Kenyatta National Hospital and its process of introducing autonomy, with regard to governance, operations and management, and finances, lead to several conclusions on replicability. The legal framework is a critical element for successfully structuring the autonomous hospital. Additionally, success is highly dependent on the extent to which there is adequate funding during the process of attaining autonomy due to the length of the transition period needed. Autonomy must be granted within the context of the national health system and national health objectives and be consistent with those aims and their underlying societal values. Finally, as with decentralization, success is dependent upon the preparation done with the systems and management necessary for the proper governance and operation of autonomous hospitals.

Autonomy-Enabled Fuel Savings for Military Vehicles: Report on 2016 Aberdeen Test Center Testing

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ragatz, Adam; Prohaska, Robert; Gonder, Jeff

Fuel savings have never been the primary focus for autonomy-enabled military vehicles. However, studies have estimated that autonomy in passenger and commercial vehicles could improve fuel economy by as much as 22%-33% over various drive cycles. If even a fraction of this saving could be realized in military vehicles, significant cost savings could be realized each year through reduced fuel transport missions, reduced fuel purchases, less maintenance, fewer required personnel, and increased vehicle range. Researchers from the National Renewable Energy Laboratory installed advanced data logging equipment and instrumentation on two autonomy-enabled convoy vehicles configured with Lockheed Martin's Autonomous Mobility Appliquemore » System to determine system performance and improve on the overall vehicle control strategies of the vehicles. Initial test results from testing conducted at the U.S. Army Aberdeen Test Center at the Aberdeen Proving Grounds are included in this report. Lessons learned from in-use testing and performance results have been provided to the project partners for continued system refinement.« less

Raising the AIQ of the Space Station

Lum, Henry; Heer, Ewald

1987-01-01

Expert systems and robotics technologies are to be significantly advanced during the Space Station program. Artificial intelligence systems (AI) on the Station will include 'scars', which will permit upgrading the AI capabilities as the Station evolves to autonomy. NASA-Ames is managing the development of the AI systems through a series of demonstrations, the first, controlling a single subsystem, to be performed in 1988. The capabilities being integrated into the first demonstration are described; however, machine learning and goal-driven natural language understanding will not reach a prototype stage until the mid-1990s. Steps which will be taken to endow the computer systems with the ability to move from heuristic reasoning to factual knowledge, i.e., learning from experience, are explored. It is noted that the development of Space Station expert systems depends on the development of experts in Station operations, which will not happen until the Station has been used extensively by crew members.

Twelve tips to stimulate intrinsic motivation in students through autonomy-supportive classroom teaching derived from self-determination theory.

PubMed

Kusurkar, R A; Croiset, G; Ten Cate, Th J

2011-01-01

Self-determination theory (SDT) of motivations distinguishes between intrinsic and extrinsic motivations. Intrinsic motivation is observed when one engages in an activity out of genuine interest and is truly self-determined. Intrinsic motivation is the desired type of motivation for study as it is associated with deep learning, better performance and positive well-being in comparison to extrinsic motivation. It is dependent on the fulfilment of three basic psychological needs described by SDT. These are the needs for autonomy, competence and relatedness. According to SDT, autonomy-supportive teaching is important, because it makes students feel autonomous and competent in their learning and also supported (relatedness) by their teachers. The concept of autonomy-supportive teaching is relevant to medical education, but less known. Through this article, we aim to make this concept understood and practically used by medical teachers. We used SDT literature as a basis to formulate these 12 tips. We present 12 practical tips derived from SDT, for teachers in health professions, on how to engage in autonomy-supportive teaching behaviours in order to stimulate intrinsic motivation in their students. These tips demonstrate that it is not difficult to engage in autonomy-supportive teaching behaviour. It can be learned through practice and self-reflection on teaching practices.

The Role of Unconditional Parental Regard in Autonomy-Supportive Parenting.

Roth, Guy; Kanat-Maymon, Yaniv; Assor, Avi

2016-12-01

Two studies explored the role of parents' unconditional positive regard (UCPR) as perceived by adolescents and young adults in promoting the effectiveness of specific parenting practices that may support offspring's academic autonomous motivation. Study 1 tested the hypothesis that UCPR predicts rationale-giving and choice-provision practices and, at the same time, moderates their relations with adolescents' autonomous motivation. Study 2 replicated the association between UCPR and the parental practices, and further explored the role of parents' authenticity as an antecedent of UCPR and parental autonomy support. Study 1 included 125 adolescents and Study 2 considered 128 college-students and their mothers. The offspring reported on their perceptions of their mothers and on their autonomous motivation, and the mothers reported on their sense of authenticity. Both studies found consistent associations between UCPR and parenting practices that may support autonomous motivation. Moreover, Study 1 demonstrated that the rationale giving and choice provision were more strongly related to adolescents' autonomous motivation when adolescents perceived mothers as high on UCPR. Finally, Study 2 demonstrated that mothers' authenticity predicted UCPR, which in turn was related to autonomy-supportive parenting. Findings support the assumption that parents' autonomy-supportive practices are more effective when accompanied by UCPR. © 2015 Wiley Periodicals, Inc.

Perception of parents as demonstrating the inherent merit of their values: relations with self-congruence and subjective well-being.

PubMed

Yu, Shi; Assor, Avi; Liu, Xiangping

2015-02-01

This study focuses on the parenting practice of inherent value demonstration (IVD), involving parents' tendency to express their values in behaviours and appear satisfied and vital while doing so. Data from Chinese college students (n = 89) confirmed the hypothesis that offspring's perception of their parents as engaged in IVD predicts offspring's subjective well-being (SWB) through sense of self-congruence. Importantly, these relations emerged also when controlling for fundamental autonomy-supportive (FAS) parenting practices such as taking children's perspective, minimising control and allowing choice. These findings are consistent with the view that parents concerned with their children's sense of autonomy may do well to engage in IVD in addition to more fundamental autonomy-supportive practices. Future research may examine the role of IVD in promoting authentic values that serve as an internal compass that guides children to act in ways that feel self-congruent. © 2014 International Union of Psychological Science.

The aim of the study was to examine the construct validity and internal consistency of the Motivational Climate in Physical Education Scale (MCPES). A key element of the development process of the scale was establishing a theoretical framework that integrated the dimensions of task- and ego involving climates in conjunction with autonomy, and social relatedness supporting climates. These constructs were adopted from the self-determination and achievement goal theories. A sample of Finnish Grade 9 students, comprising 2,594 girls and 1,803 boys, completed the 18-item MCPES during one physical education class. The results of the study demonstrated that participants had highest mean in task-involving climate and the lowest in autonomy climate and ego-involving climate. Additionally, autonomy, social relatedness, and task- involving climates were significantly and strongly correlated with each other, whereas the ego- involving climate had low or negligible correlations with the other climate dimensions.The construct validity of the MCPES was analyzed using confirmatory factor analysis. The statistical fit of the four-factor model consisting of motivational climate factors supporting perceived autonomy, social relatedness, task-involvement, and ego-involvement was satisfactory. The results of the reliability analysis showed acceptable internal consistencies for all four dimensions. The Motivational Climate in Physical Education Scale can be considered as psychometrically valid tool to measure motivational climate in Finnish Grade 9 students. Key PointsThis study developed Motivational Climate in School Physical Education Scale (MCPES). During the development process of the scale, the theoretical framework using dimensions of task- and ego involving as well as autonomy, and social relatedness supporting climates was constructed.

2013-01-01

Background We lack national and cross-national studies of physicians’ perceptions of quality of patient care, professional autonomy, and job satisfaction to inform clinicians and policymakers. This study aims to compare such perceptions in Canada, the United States (U.S.), and Norway. Methods We analyzed data from large, nationwide, representative samples of physicians in Canada (n = 3,083), the U.S. (n = 6,628), and Norway (n = 638), examining demographics, job satisfaction, and professional autonomy. Results Among U.S. physicians, 79% strongly agreed/agreed they could provide high quality patient care vs. only 46% of Canadian and 59% of Norwegian physicians. U.S. physicians also perceived more clinical autonomy and time with their patients, with differences remaining significant even after controlling for age, gender, and clinical hours. Women reported less adequate time, clinical freedom, and ability to provide high-quality care. Country differences were the strongest predictors for the professional autonomy variables. In all three countries, physicians’ perceptions of quality of care, clinical freedom, and time with patients influenced their overall job satisfaction. Fewer U.S. physicians reported their overall job satisfaction to be at-least-somewhat satisfied than did Norwegian and Canadian physicians. Conclusions U.S. physicians perceived higher quality of patient care and greater professional autonomy, but somewhat lower job satisfaction than their colleagues in Norway and Canada. Differences in health care system financing and delivery might help explain this difference; Canada and Norway have more publicly-financed, not-for-profit health care delivery systems, vs. a more-privately-financed and profit-driven system in the U.S. None of these three highly-resourced countries, however, seem to have achieved an ideal health care system from the perspective of their physicians.

Bilateral effects of hospital patient-safety procedures on nurses' job satisfaction.

The aim of this study was to examine how hospital patient-safety procedures affect the job satisfaction of hospital nurses. Additionally, we investigated the association between perceived autonomy and hospital patient-safety procedures and job satisfaction. Recently, measures for patient safety have been recognized as an essential requirement in hospitals. Hospital patient-safety procedures may enhance the job satisfaction of nurses by improving the quality of their work. However, such procedures may also decrease their job satisfaction by imposing excessive stress on nurses because they cannot make mistakes. The participants included 537 nurses at 10 private hospitals in Japan (The surveys were collected from March to July 2012). Factors related to hospital patient-safety procedures were demonstrated using factor analysis, and the associations between these factors and nurses' self-perceived autonomy and job satisfaction were examined using structural equation modelling. Five factors regarding hospital patient-safety procedures were extracted. Additionally, structural equation modelling revealed statistically significant associations between these factors and the nurses' self-perceived autonomy and job satisfaction. The findings showed that nurses' perceived autonomy of the workplace enhanced their job satisfaction and that their perceptions of hospital patient-safety procedures promoted their job satisfaction. However, some styles of chief nurses' leadership regarding patient safety restrict nurses' independent and autonomous decision-making and actions, resulting in a lowering of job satisfaction. This study demonstrated that hospital patient-safety procedures have ambiguous effects on nurses' job satisfaction. In particular, chief nurses' leadership relating to patient safety can have a positive or negative effect on nurses' job satisfaction. The findings indicated that hospital managers should demonstrate positive attitudes to improve patient safety for nurses' job satisfaction. In addition, policymakers in the hospitals should consider that chief nurses' leadership styles may reduce autonomy and suppress nurses' job satisfaction. © 2017 The Authors International Nursing Review published by John Wiley & Sons Ltd on behalf of International Council of Nurses.

Limits to relational autonomy--the Singaporean experience.

PubMed

Krishna, Lalit Kumar Radha; Watkinson, Deborah S; Beng, Ng Lee

2015-05-01

Recognition that the Principle of Respect for Autonomy fails to work in family-centric societies such as Singapore has recently led to the promotion of relational autonomy as a suitable framework within which to place healthcare decision making. However, empirical data, relating to patient and family opinions and the practices of healthcare professionals in Confucian-inspired Singapore, demonstrate clear limitations on the ability of a relational autonomy framework to provide the anticipated compromise between prevailing family decision-making norms and adopted Western led atomistic concepts of autonomy. Evidence suggests that despite a growing infusion of Western influence, there is still little to indicate any major shift to individual decision making, particularly in light of the way society and healthcare are structured. Similarly, the lack of employing a shared decision-making model and data that discredit the notion that the complex psychosocial and cultural factors that affect the decision making may be considered "content neutral" not only prevents the application of relational autonomy but questions the viability of the values behind the Principle of Respect for Autonomy. Taking into account local data and drawing upon a wider concept of personhood that extends beyond prevailing family-centric ideals along with the complex interests that are focused upon the preservation of the unique nature of personhood that arises from the Ring Theory of Personhood, we propose and "operationalize" the employing of an authoritative welfare-based approach, within the confines of best interest decision making, to better meet the current care needs within Singapore. © The Author(s) 2014.

Autonomy and Automation

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.

Autonomy for Constellation

Truszkowski, Walt; Szczur, Martha R. (Technical Monitor)

2000-01-01

The newer types of space systems, which are planned for the future, are placing challenging demands for newer autonomy concepts and techniques. Motivating these challenges are resource constraints. Even though onboard computing power will surely increase in the coming years, the resource constraints associated with space-based processes will continue to be a major factor that needs to be considered when dealing with, for example, agent-based spacecraft autonomy. To realize "economical intelligence", i.e., constrained computational intelligence that can reside within a process under severe resource constraints (time, power, space, etc.), is a major goal for such space systems as the Nanosat constellations. To begin to address the new challenges, we are developing approaches to constellation autonomy with constraints in mind. Within the Agent Concepts Testbed (ACT) at the Goddard Space Flight Center we are currently developing a Nanosat-related prototype for the first of the two-step program.

Cognitive Architectures and Autonomy: A Comparative Review

NASA Astrophysics Data System (ADS)

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.

This paper considers incorporating autonomy into human-centric Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) environments. Specifically, it focuses on identifying ways that current autonomy technologies can augment human control and the challenges presented by additive autonomy. Three approaches to this challenge are considered, stemming from prior work in two converging areas. In the first, the problem is approached as augmenting what humans currently do with automation. In the alternate approach, the problem is approached as treating humans as actors within a cyber-physical system-of-systems (stemming from robotic distributed computing). A third approach, combines elements of both of the aforementioned.

A woman's lack of or limited reproductive autonomy could lead to adverse health effects, feeling of being inferior, and above all being unable to adequately care for her children. Little is known about the reproductive autonomy of married Ikwerre women of Rivers State, Nigeria. This study demonstrates how Ikwerre women understand the terms autonomy and reproductive rights and what affects the exercise of these rights. An exploratory research design was employed for this study. A semi-structured interview schedule was used to conduct thirty-four in-depth interviews and six focus group discussions with purposively sampled educated, semi-educated, and uneducated Ikwerre women in monogamous or polygynous marriages. The collected data was analysed qualitatively with MAXQDA 11 using open and axial coding. The interviews and focus group responses reveal a low level of awareness of autonomy and reproductive rights amongst the Ikwerre women in Nigeria. While some educated women were aware of their reproductive rights, cultural practices were reported to limit the exercise of these rights. Participants reported that Ikwerre culture is a patriarchal one where married women are expected to submit and obey their husbands in all matters; and a good married woman according to Ikwerre standard is one who complies with this culture. Women's refusal of sexual advances from their husbands is described as not being acceptable in this culture; and hence rape in marriage is not recognized in Ikwerre culture. Education and awareness creation on the importance of women's reproductive autonomy could improve their reproductive rights and autonomy in marital settings. Overcoming the patriarchal aspects of Ikwerre culture-for example, the greater value placed on male children than female children and treating women as incompetent individuals-is necessary to promote gender equality as well as help improve women's reproductive autonomy.

Increasing autonomous systems within the aircraft cockpit begins with an effort to understand what autonomy is and developing the technology that encompasses it. Autonomy allows an agent, human or machine, to act independently within a circumscribed set of goals; delegating responsibility to the agent(s) to achieve overall system objective(s). Increasingly Autonomous Systems (IAS) are the highly sophisticated progression of current automated systems toward full autonomy. Working in concert with humans, these types of technologies are expected to improve the safety, reliability, costs, and operational efficiency of aviation. IAS implementation is imminent, which makes the development and the proper performance of such technologies, with respect to cockpit operation efficiency, the management of air traffic and data communication information, vital. A prototype IAS agent that attempts to optimize the identification and distribution of "relevant" air traffic data to be utilized by human crews during complex airspace operations has been developed.

A Distributed Aperture Vision System for ground vehicles is described. An overview of the hardware including sensor pod, processor, video compression, and displays is provided. This includes a discussion of the choice between an integrated sensor pod and individually mounted sensors, open architecture design, and latency issues as well as flat panel versus head mounted displays. This technology is applied to various ground vehicle scenarios, including closed-hatch operations (operator in the vehicle), remote operator tele-operation, and supervised autonomy for multi-vehicle unmanned convoys. In addition, remote vision for automatic perimeter surveillance using autonomous vehicles and automatic detection algorithms is demonstrated.

Predictors of nurse practitioners' autonomy: effects of organizational, ethical, and market characteristics.

To identify the predictors of autonomy of nurse practitioners (NPs) affiliated directly and/or indirectly with managed-care systems (e.g., HMOs). A mailed survey sent to a stratified random sample of 254 NPs certified and licensed to practice in the state of Maryland. The measures consisted of selected organizational characteristics; market factors of HMO penetration and percentage of client population enrolled in managed care; and factors of ethical concern, such as ethical ideology, ethics education, and autonomy. The County Surveyor Database was used to assess market penetration in the state. Although NPs were ethically concerned about their autonomy in a managed-care environment (70.2%), actual autonomy scores were high. The higher the percentage of HMO penetration, percentage of client population enrolled in managed care, and perceived ethical concern, the lower the perceived autonomy of NPs. Findings may be used for future research to address the complexity of variables that influence the autonomous practice of NPs.

To describe perceived participation and autonomy among a sample of persons with stroke in Iran and to identify different aspects of functioning and contextual factors predicting participation after stroke. A cross-sectional study. A total of 102 persons, between 27 and 75 years of age, diagnosed with first-ever stroke. Participants were assessed for different aspects of functioning, contextual factors and health conditions. Participation was assessed using the Persian version of the Impact on Participation and Autonomy questionnaire. This study demonstrated that the majority of the study population perceived their participation and autonomy to be good to fair in the different domains of their participation, but not with respect to the autonomy outdoors domain. In addition, physical function was found to be the most important variable predicting performance-based participation, whereas mood state was the most important variable predicting social-based participation. The results emphasize the importance of physical function, mood state and access to caregiving services as predictors of participation in everyday life after stroke. Whilst there are two dimensions of participation in this Persian sample of persons with stroke, the factors explaining participation seem to be the same across the cultures.

Promoting the Avoidance of High-Calorie Snacks: Priming Autonomy Moderates Message Framing Effects

The beneficial effects of gain-framed vs. loss-framed messages promoting health protective behaviors have been found to be inconsistent, and consideration of potential moderating variables is essential if framed health promotion messages are to be effective. This research aimed to determine the influence of highlighting autonomy (choice and freedom) and heteronomy (coercion) on the avoidance of high-calorie snacks following reading gain-framed or loss-framed health messages. In Study 1 (N = 152) participants completed an autonomy, neutral, or heteronomy priming task, and read a gain-framed or loss-framed health message. In Study 2 (N = 242) participants read a gain-framed or loss-framed health message with embedded autonomy or heteronomy primes. In both studies, snacking intentions and behavior were recorded after seven days. In both studies, when autonomy was highlighted, the gain-framed message (compared to the loss-framed message) resulted in stronger intentions to avoid high-calorie snacks, and lower self-reported snack consumption after seven days. Study 2 demonstrated this effect occurred only for participants to whom the information was most relevant (BMI>25). The results suggest that messages promoting healthy dietary behavior may be more persuasive if the autonomy-supportive vs. coercive nature of the health information is matched to the message frame. Further research is needed to examine potential mediating processes. PMID:25078965

The current trend in surgery toward further trauma reduction inevitably leads to increased technological complexity. It must be assumed that this situation will not stay under the sole control of surgeons; mechanical systems will assist them. Certain segments of the work flow will likely have to be taken over by a machine in an automatized or autonomous mode. In addition to the analysis of our own surgical practice, a literature search of the Medline database was performed to identify important aspects, methods, and technologies for increased operating room (OR) autonomy. Robotic surgical systems can help to increase OR autonomy by camera control, application of intelligent instruments, and even accomplishment of automated surgical procedures. However, the important step from simple task execution to autonomous decision making is difficult to realize. Another important aspect is the adaption of the general technical OR environment. This includes adaptive OR setting and context-adaptive interfaces, automated tool arrangement, and optimal visualization. Finally, integration of peri- and intraoperative data consisting of electronic patient record, OR documentation and logistics, medical imaging, and patient surveillance data could increase autonomy. To gain autonomy in the OR, a variety of assistance systems and methodologies need to be incorporated that endorse the surgeon autonomously as a first step toward the vision of cognitive surgery. Thus, we require establishment of model-based surgery and integration of procedural tasks. Structured knowledge is therefore indispensable.

Toward sensor modular autonomy for persistent land intelligence surveillance and reconnaissance (ISR)

Currently, most land Intelligence, Surveillance and Reconnaissance (ISR) assets (e.g. EO/IR cameras) are simply data collectors. Understanding, decision making and sensor control are performed by the human operators, involving high cognitive load. Any automation in the system has traditionally involved bespoke design of centralised systems that are highly specific for the assets/targets/environment under consideration, resulting in complex, non-flexible systems that exhibit poor interoperability. We address a concept of Autonomous Sensor Modules (ASMs) for land ISR, where these modules have the ability to make low-level decisions on their own in order to fulfil a higher-level objective, and plug in, with the minimum of preconfiguration, to a High Level Decision Making Module (HLDMM) through a middleware integration layer. The dual requisites of autonomy and interoperability create challenges around information fusion and asset management in an autonomous hierarchical system, which are addressed in this work. This paper presents the results of a demonstration system, known as Sensing for Asset Protection with Integrated Electronic Networked Technology (SAPIENT), which was shown in realistic base protection scenarios with live sensors and targets. The SAPIENT system performed sensor cueing, intelligent fusion, sensor tasking, target hand-off and compensation for compromised sensors, without human control, and enabled rapid integration of ISR assets at the time of system deployment, rather than at design-time. Potential benefits include rapid interoperability for coalition operations, situation understanding with low operator cognitive burden and autonomous sensor management in heterogenous sensor systems.

Item Response Theory analysis of the Autonomy over Tobacco Scale (AUTOS).

Wellman, Robert J; Edelen, Maria Orlando; DiFranza, Joseph R

2015-06-01

The Autonomy over Tobacco Scale (AUTOS) is composed of 12-symptoms of nicotine dependence. While it has demonstrated excellent reliability and validity, several psychometric properties have yet to be investigated. We aimed to determine (1) whether items functioned differently across demographic groups, (2) the likelihood that individual symptoms would be endorsed by smokers at different levels of diminished autonomy, and (3) the degree of information provided by each item and the reliability of the full AUTOS across the range of diminished autonomy. Data for this study come from two convenience samples of American adult current smokers (n=777; 69% female; 88% white; Mage=34 years, range: 18-78), of whom 66% were daily smokers (Mcigarettes/smoking day=10.1, range: <1-70). Participants completed the AUTOS online as part of "a research study about the experiences people have when they smoke." After p value correction, items remained invariant across sex and minority status, while two items functioned differently according to age, with minimal impact on the total AUTOS score. Discriminative power of the items was high. The greatest amount of information is provided at just under one-half SD above the mean and the least at the extremes of diminished autonomy. The AUTOS maintains acceptable reliability (>0.70) across the range of diminished autonomy within which more than 95% of smokers' scores could be anticipated to fall. The AUTOS is a versatile and psychometrically sound instrument for measuring the loss of autonomy over tobacco use. Copyright © 2015 Elsevier Ltd. All rights reserved.

Parental autonomy support and ethnic culture identification among second-generation immigrants.

PubMed

Abad, Neetu S; Sheldon, Kennon M

2008-08-01

Born and raised in the United States, children of immigrants often face conflict over whether to endorse the norms and traditions of the family's country of origin (the natal culture) or those of mainstream U.S. society (the host culture). The authors hypothesized that when immigrant parents allow children to make their own choices concerning their cultural identity, their children will be more likely to internalize the natal culture and will experience greater well-being. Ninety-nine college-aged 2nd-generation immigrants rated their well-being, perceptions of their mother's and father's autonomy support, and their endorsement of both natal and U.S. cultures. Results demonstrated that paternal, but not maternal, autonomy support predicted greater well-being and greater endorsement of the natal culture and that immersion in the natal culture predicted some indices of well-being. Several explanations for the possibly greater significance of paternal versus maternal autonomy support in the context of immigrant families are considered.

Verification and Validation of Autonomy Software at NASA

Autonomous software holds the promise of new operation possibilities, easier design and development and lower operating costs. However, as those system close control loops and arbitrate resources on board with specialized reasoning, the range of possible situations becomes very large and uncontrollable from the outside, making conventional scenario-based testing very inefficient. Analytic verification and validation (V&V) techniques, and model checking in particular, can provide significant help for designing autonomous systems in a more efficient and reliable manner, by providing a better coverage and allowing early error detection. This article discusses the general issue of V&V of autonomy software, with an emphasis towards model-based autonomy, model-checking techniques and concrete experiments at NASA.

Denmark has implemented a comprehensive, nationwide pharmaceutical information system, and this system has been evaluated by the Danish Council of Ethics. The system can be seen as an exemplar of a comprehensive health information system for clinical use. The paper analyses 1) how informed consent can be implemented in the system and how different implementations create different impacts on autonomy and control of information, and 2) arguments directed towards justifying not seeking informed consent in this context. Based on the analysis a heuristic is provided which enables a ranking and estimation of the impact on autonomy and control of information of different options for consent to entry of data into the system and use of data from the system.The danger of routinisation of consent is identified.The Danish pharmaceutical information system raises issues in relation to autonomy and control of information, issues that will also occur in relation to other similar comprehensive health information systems. Some of these issues are well understood and their impact can be judged using the heuristic which is provided. More research is, however needed in relation to routinisation of consent.

Future Mars rover missions will require more advanced onboard autonomy for increased scientific productivity and reduced mission operations cost. One such form of autonomy can be achieved by targeting precise science measurements to be made in a single command uplink cycle. In this paper we present an overview of our solution to the subproblems of navigating a rover into place for microscopic imaging, mapping an instrument target point selected by an operator using far away science camera images to close up hazard camera images, verifying the safety of placing a contact instrument on a sample or finding nearby safe points, and analyzing the data that comes back from the rover. The system developed includes portions used in the Multiple Target Single Cycle Instrument Placement demonstration at NASA Ames in October 2004, and portions of the MI Toolkit delivered to the Athena Microscopic Imager Instrument Team for the MER mission still operating on Mars today. Some of the component technologies are also under consideration for MSL mission infusion.

The implementation and use of evidence-based practices is a key priority for recovery-oriented mental health service provision. Training and development programmes for employees continue to be a key method of knowledge and skill development, despite acknowledged difficulties with uptake and maintenance of behaviour change. Self-determination theory suggests that autonomy, or a sense that behaviour is self-generated, is a key motivator to sustained behaviour change, in this case practices in mental health services. This study examined the utility of values-focused staff intervention as a specific, reproducible method of autonomy support. Mental health workers (n = 146) were assigned via cluster randomisation to either a values clarification condition or an active problem-solving control condition. Results demonstrated that a structured values clarification exercise was useful in promoting integrated motivation for the changed practice and resulted in increased implementation planning. Structured values clarification intervention demonstrates utility as a reproducible means of autonomy support within the workplace. We discuss future directions for the study of autonomous motivation in the field of implementation science. ACTRN12613000353796.

Objective American Indians (AI) have a high prevalence of electronic nicotine delivery system (ENDS) use. However, little information exists on (ENDS) use, either alone or in combination with cigarettes (dual use), among AI. The objective of this small-scaled study was to examine use behaviours and dependence among exclusive ENDS users and dual users of AI descent. Exclusive smokers were included for comparison purposes. Setting Oklahoma, USA. Participants Adults of AI descent who reported being exclusive ENDS users (n=27), dual users (n=28) or exclusive cigarette smokers (n=27). Measures Participants completed a detailed questionnaire on use behaviours. The Hooked on Nicotine Checklist (HONC) was used to assess loss of autonomy over cigarettes and was reworded for ENDS. Dual users completed the HONC twice. Sum of endorsed items indicated severity of diminished autonomy. Comparisons were made with non-parametric methods and statistical significance was defined as P<0.05. Results Median duration of ENDS use was 2 years among ENDS users and 1 year among dual users. Most ENDS and dual users reported <20 vape sessions per day (72.0% vs 72.0%) with ≤10 puffs per vape session (70.4% vs 69.2%). Severity of diminished autonomy over ENDS was similar among ENDS and dual users (medians: 4 vs 3; P=0.6865). Among dual users, severity of diminished autonomy was lower for ENDS than cigarettes (medians: 3 vs 9; P=<0.0001). Comparing ENDS users with smokers, ENDS users had a lower severity of diminished autonomy (4 vs 8; P=0.0077). Comparing dual users with smokers, median severity of diminished autonomy over cigarettes did not differ (P=0.6865). Conclusions Severity of diminished autonomy was lower for ENDS than cigarettes in this small sample of AI. Future, adequately powered studies should be conducted to fully understand ENDS use patterns and dependence levels in this population. PMID:29259060

1984-01-01

This report presents an informal survey of experts in the field of spacecraft automation, with recommendations for which technologies should be given the greatest development attention for implementation on the initial 1990's NASA Space Station. The recommendations implemented an autonomy philosophy that was developed by the Concept Development Group's Autonomy Working Group during 1983. They were based on assessments of the technologies' likely maturity by 1987, and of their impact on recurring costs, non-recurring costs, and productivity. The three technology areas recommended for programmatic emphasis were: (1) artificial intelligence expert (knowledge based) systems and processors; (2) fault tolerant computing; and (3) high order (procedure oriented) computer languages. This report also describes other elements required for Station autonomy, including technologies for later implementation, system evolvability, and management attitudes and goals. The cost impact of various technologies is treated qualitatively, and some cases in which both the recurring and nonrecurring costs might be reduced while the crew productivity is increased, are also considered. Strong programmatic emphasis on life cycle cost and productivity is recommended.

Systems, methods, and user interfaces are used for controlling a robot. An environment map and a robot designator are presented to a user. The user may place, move, and modify task designators on the environment map. The task designators indicate a position in the environment map and indicate a task for the robot to achieve. A control intermediary links task designators with robot instructions issued to the robot. The control intermediary analyzes a relative position between the task designators and the robot. The control intermediary uses the analysis to determine a task-oriented autonomy level for the robot and communicates targetmore » achievement information to the robot. The target achievement information may include instructions for directly guiding the robot if the task-oriented autonomy level indicates low robot initiative and may include instructions for directing the robot to determine a robot plan for achieving the task if the task-oriented autonomy level indicates high robot initiative.« less

Basic autonomy as a fundamental step in the synthesis of life.

PubMed

Ruiz-Mirazo, Kepa; Moreno, Alvaro

2004-01-01

In the search for the primary roots of autonomy (a pivotal concept in Varela's comprehensive understanding of living beings), the theory of autopoiesis provided an explicit criterion to define minimal life in universal terms, and was taken as a guideline in the research program for the artificial synthesis of biological systems. Acknowledging the invaluable contribution of the autopoietic school to present biological thinking, we offer an alternative way of conceiving the most basic forms of autonomy. We give a bottom-up account of the origins of "self-production" (or self-construction, as we propose to call it), pointing out which are the minimal material and energetic requirements for the constitution of basic autonomous systems. This account is, indeed, committed to the project of developing a general theory of biology, but well grounded in the universal laws of physics and chemistry. We consider that the autopoietic theory was formulated in highly abstract terms and, in order to advance in the implementation of minimal autonomous systems (and, at the same time, make major progress in exploring the origins of life), a more specific characterization of minimal autonomous systems is required. Such a characterization will not be drawn from a review of the autopoietic criteria and terminology (à la Fleischaker) but demands a whole reformulation of the question: a proper naturalization of the concept of autonomy. Finally, we also discuss why basic autonomy, according to our account, is necessary but not sufficient for life, in contrast with Varela's idea that autopoiesis was a necessary and sufficient condition for it.

The impact of within-school autonomy on students' goal orientations and engagement with mathematics

2017-03-01

School autonomy has been identified as having an impact on a school's performance, yet less has been reported about the effect this has on students' goal orientations and engagement with mathematics. In a national study conducted in schools across Australia, measures of school autonomy were collected from teachers and school leaders, along with students' perceptions of the mastery and performance goal orientations of their classrooms and personally using surveys. Schools were identified as having high or low levels of autonomy on the basis of school leaders' responses. For the study discussed in this paper, a subset of 14 schools for which matched student and teacher data were available provided students' responses to a variety of variables including goal orientations. The findings suggested students in high-autonomy schools were less likely to hold a personal performance approach and avoidance goals than their peers in low-autonomy schools. Fifty-five case studies conducted in 52 schools provided evidence of some of the practical aspects of these findings, which have implications for systems, schools and teachers.

Image-Based Visual Servoing for Robotic Systems: A Nonlinear Lyapunov-Based Control Approach

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dixon, Warren

2004-06-01

There is significant motivation to provide robotic systems with improved autonomy as a means to significantly accelerate deactivation and decommissioning (D&D) operations while also reducing the associated costs, removing human operators from hazardous environments, and reducing the required burden and skill of human operators. To achieve improved autonomy, this project focused on the basic science challenges leading to the development of visual servo controllers. The challenge in developing these controllers is that a camera provides 2-dimensional image information about the 3-dimensional Euclidean-space through a perspective (range dependent) projection that can be corrupted by uncertainty in the camera calibration matrix andmore » by disturbances such as nonlinear radial distortion. Disturbances in this relationship (i.e., corruption in the sensor information) propagate erroneous information to the feedback controller of the robot, leading to potentially unpredictable task execution. This research project focused on the development of a visual servo control methodology that targets compensating for disturbances in the camera model (i.e., camera calibration and the recovery of range information) as a means to achieve predictable response by the robotic system operating in unstructured environments. The fundamental idea is to use nonlinear Lyapunov-based techniques along with photogrammetry methods to overcome the complex control issues and alleviate many of the restrictive assumptions that impact current robotic applications. The outcome of this control methodology is a plug-and-play visual servoing control module that can be utilized in conjunction with current technology such as feature recognition and extraction to enable robotic systems with the capabilities of increased accuracy, autonomy, and robustness, with a larger field of view (and hence a larger workspace). The developed methodology has been reported in numerous peer-reviewed publications and the performance and enabling capabilities of the resulting visual servo control modules have been demonstrated on mobile robot and robot manipulator platforms.« less

A Human-Autonomy Teaming Approach for a Flight-Following Task

Brandt, Summer L.; Russell, Ricky; Lachter, Joel; Shively, Robert

2017-01-01

Managing aircraft is becoming more complex with increasingly sophisticated automation responsible for more flight tasks. With this increased complexity, it is becoming more difficult for operators to understand what the automation is doing and why. Human involvement with increasingly autonomous systems must adjust to allow for a more dynamic relationship involving cooperation and teamwork. As part of an ongoing project to develop a framework for human-autonomy teaming (HAT) in aviation, a part-task study was conducted to demonstrate, evaluate and refine proposed critical aspects of HAT. These features were built into an automated recommender system on a ground station available from previous studies. Participants performed a flight-following task once with the original ground station (i.e., No HAT condition) and once with the HAT features enabled (i.e., HAT condition). Behavioral and subjective measures were collected; subjective measures are presented here. Overall, participants preferred the ground station with HAT features enabled compared to the station without the HAT features. Participants reported that the HAT displays and automation were preferred for keeping up with operationally important issues. Additionally, participants reported that the HAT displays and automation provided enough situation awareness to complete the task and reduced workload relative to the No HAT baseline.

Vehicle guidance for General Dynamics' NASP vehicle is planned to be self-contained onboard the vehicle, and independent of any ground support during the mission. It will include real-time onboard abort and ascent trajectory optimization capability. Although these features should be considered a natural outgrowth of research in guidance and trajectory optimization and advances in computation, facilitating full vehicle autonomy for NASP represents a significant advance relative to any flight-demonstrated guidance. Algorithms and processing requirements for autonomous NASP vehicle guidance are considered.

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.

Service with a smile: do emotional intelligence, gender, and autonomy moderate the emotional labor process?

PubMed

Johnson, Hazel-Anne M; Spector, Paul E

2007-10-01

This survey study of 176 participants from eight customer service organizations investigated how individual factors moderate the impact of emotional labor strategies on employee well-being. Hierarchical regression analyses indicated that gender and autonomy were significant moderators of the relationships between emotional labor strategies and the personal outcomes of emotional exhaustion, affective well-being, and job satisfaction. Females were more likely to experience negative consequences when engaging in surface acting. Autonomy served to alleviate negative outcomes for individuals who used emotional labor strategies often. Contrary to our hypotheses, emotional intelligence did not moderate the relationship between the emotional labor strategies and personal outcomes. Results demonstrated how the emotional labor process can influence employee well-being. (c) 2007 APA, all rights reserved.

Medical Systems Engineering to Support Mars Mission Crew Autonomy

NASA Technical Reports Server (NTRS)

Antonsen, Erik; Mindock, Jennifer

2017-01-01

Human spaceflight missions to Mars face exceptionally challenging resource limitations that far exceed those faced before. Increasing transit times, decreasing opportunity for resupply, communications challenges, and extended time to evacuate a crew to definitive medical care dictate a level of crew autonomy in medical care that is beyond the current medical model. To approach this challenge, a medical systems engineering approach is proposed that relies on a clearly articulated Concept of Operations and risk analysis tools that are in development at NASA. This paper proposes an operational clinical model with key terminology and concepts translated to a controls theory paradigm to frame a common language between clinical and engineering teams. This common language will be used for design and validation of an exploration medical system that is fully integrated into a Mars transit vehicle. This approach merges medical simulation, human factors evaluation techniques, and human-in-the-loop testing in ground based analogs to tie medical hardware and software subsystem performance and overall medical system functionality to metrics of operational medical autonomy. Merging increases in operational clinical autonomy with a more restricted vehicle system resource scenario in interplanetary spaceflight will require an unprecedented level of medical and engineering integration. Full integration of medical capabilities into a Mars vehicle system may require a new approach to integrating medical system design and operations into the vehicle Program structure. Prior to the standing-up of a Mars Mission Program, proof of concept is proposed through the Human Research Program.

Folta, David; Bristow, John; Hawkins, Albin; Dell, Greg

2002-01-01

NASA's first autonomous formation flying mission, the New Millennium Program's (NMP) Earth Observing-1 (EO-1) spacecraft, recently completed its principal goal of demonstrating advanced formation control technology. This paper provides an overview of the evolution of an onboard system that was developed originally as a ground mission planning and operations tool. We discuss the Goddard Space Flight Center s formation flying algorithm, the onboard flight design and its implementation, the interface and functionality of the onboard system, and the implementation of a Kalman filter based GPS data smoother. A number of safeguards that allow the incremental phasing in of autonomy and alleviate the potential for mission-impacting anomalies from the on- board autonomous system are discussed. A comparison of the maneuvers planned onboard using the EO-1 autonomous control system to those from the operational ground-based maneuver planning system is presented to quantify our success. The maneuvers discussed encompass reactionary and routine formation maintenance. Definitive orbital data is presented that verifies all formation flying requirements.

NASA aeronautics research has made decades of contributions to aviation. Both aircraft and air traffic management (ATM) systems in use today contain NASA-developed and NASA sponsored technologies that improve safety and efficiency. Recent innovations in robotics and autonomy for automobiles and unmanned systems point to a future with increased personal mobility and access to transportation, including aviation. Automation and autonomous operations will transform the way we move people and goods. Achieving this mobility will require safe, robust, reliable operations for both the vehicle and the airspace and challenges to this inevitable future are being addressed now in government labs, universities, and industry. These challenges are the focus of NASA Langley Research Center's Autonomy Incubator whose R&D portfolio includes mission planning, trajectory and path planning, object detection and avoidance, object classification, sensor fusion, controls, machine learning, computer vision, human-machine teaming, geo-containment, open architecture design and development, as well as the test and evaluation environment that will be critical to prove system reliability and support certification. Safe autonomous operations will be enabled via onboard sensing and perception systems in both data-rich and data-deprived environments. Applied autonomy will enable safety, efficiency and unprecedented mobility as people and goods take to the skies tomorrow just as we do on the road today.

School nurses' perceptions of empowerment and autonomy.

DeSisto, Marie C; DeSisto, Thomas Patrick

2004-08-01

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.

Work-related stress among physicians has been an issue of growing concern in recent years. How and why this may vary between different health care systems remains poorly understood. Using an established theoretical model (effort-reward imbalance), this study analyses levels of work stress among primary care physicians (PCPs) in three different health care systems, the United States, the United Kingdom and Germany. Whether professional autonomy and specific features of the work environment are associated with work stress and account for possible country differences are examined. Data are derived from self-administered questionnaires obtained from 640 randomly sampled physicians recruited for an international comparative study of medical decision making conducted from 2005 to 2007. Results demonstrate country-specific differences in work stress with the highest level in Germany, intermediate level in the US and lowest level among UK physicians. A negative correlation between professional autonomy and work stress is observed in all three countries, but neither this association nor features of the work environment account for the observed country differences. Whether there will be adequate numbers of PCPs, or even a field of primary care in the future, is of increasing concern in several countries. To the extent that work-related stress contributes to this, identification of its organizational correlates in different health care systems may offer opportunities for remedial interventions.

[The issue of autonomy in medical ethics: philosophy of Karol Wojtyła].

PubMed

Niebrój, Lesław T; Olejniczak, Marek; Kruźlak, Agnieszka

2007-01-01

The issue of autonomy seems to play a very central and fundamental role in contemporary medical ethics. However, it should be emphasized, that there is no agreement on how the concept of autonomy ought to be understood. Although as the main intellectual framework to describe the meaning of "autonomy" is the use of philosophical system of John St. Mill or Immanuel Kant, one could identify the tendency to redefine the concept under study. The aim of this article was to find out if the philosophy of Karol Wojtyla could provide--interesting from the bioethical point of view--insights into understanding of the idea of autonomy. The Wojtyla's critique of Kant's and Mill's understanding of autonomy was shortly described and the main elements of Wojtyla's concept of autonomy were analyzed. On the basis of these considerations it was assumed that philosophical background of Wojtyla is so different from those which are used in the contemporary, especially so called Anglo-American, bioethics that introducing it "elements" of his thinking would lead to misunderstandings and indeed even serious errors. On the other hand, however, philosophical works of Wojtyla seems to be very influential in developing 'personalistic' bioethics. But this bioethics could be accepted only by people who share Wojtyla's ontological and probably also theological or religious assumptions.

The micropolitics of responsibility vis-à-vis autonomy: parental accounts of childhood genetic testing and (non)disclosure.

PubMed

Arribas-Ayllon, Michael; Sarangi, Srikant; Clarke, Angus

2008-03-01

Genetic testing and (non)disclosure of genetic information present ethical and moral dilemmas for the management of parental responsibility vis-à-vis the child's autonomy. Ethical guidelines aimed at professionals currently seek to defer childhood testing where there is no clear medical or psychosocial benefit. This version of autonomy is derived from a bioethical paradigm which brackets the individual rights and capacities of the child. In this paper we focus on situated parental accounts of responsibility/autonomy to understand the complex forms of relational work -i.e. the micropolitics of balancing rights and responsibilities - involving a range of inherited genetic disorders. Interviews (n= 20) were conducted with parents whose genetic condition may have had consequences for their children. Using rhetorical discourse analysis, we show how parents draw upon a number of rhetorical/discoursal devices to produce accounts where genetic responsibility is actually or potentially transmitted to the child. We identify three kinds of accounting practice: (1) aligned responsibility; (2) deferred responsibility; and (3) misaligned responsibility. Each of these practices demonstrates how parents position themselves responsibly by foregrounding figures and events onto which the child's autonomy is selectively mapped. Rather than simple representations, we regard these accounts as complex moral performances that seek alignment with broader bioethical discourses.

G-autonomy of EEG recordings of psychotic patients undergoing the primitive expression form of dance therapy

Primitive expression (PE) is a form of dance therapy (DT) that involves an interaction of ethologically and socially based forms which are supplied for re-enactment. Brain connectivity has been measured in electroencephalographic (EEG) data of patients with schizophrenia undergoing PE DT, using the correlation coefficient and mutual information. These parameters do not measure the existence or absence of directionality in the connectivity. The present study investigates the use of the G-autonomy measure of EEG electrode voltages of the same group of schizophrenic patients. G-autonomy is a measure of the “autonomy” of a system. It indicates the degree by which prediction of the system's future evolution is enhanced by taking into account its own past states, in comparison to predictions based on past states of a set of external variables. In the present research, “own” past states refer to voltage values in the time series recorded at a specific electrode and “external” variables refer to the voltage values recorded at other electrodes. Indication is provided for an acute effect of early-stage PE DT expressed by the augmentation of G-autonomy in the delta rhythm and an acute effect of late- stage PE DT expressed by the reduction of G-autonomy in the theta and alpha rhythms.

The dynamic nature of the Cargo Transfer Vehicle's (CTV) mission and the high level of autonomy required mandate a complete fault management system capable of operating under uncertain conditions. Such a fault management system must take into account the current mission phase and the environment (including the target vehicle), as well as the CTV's state of health. This level of capability is beyond the scope of current on-board fault management systems. This presentation will discuss work in progress at TRW to apply artificial intelligence to the problem of on-board fault management. The goal of this work is to develop fault management systems. This presentation will discuss work in progress at TRW to apply artificial intelligence to the problem of on-board fault management. The goal of this work is to develop fault management systems that can meet the needs of spacecraft that have long-range autonomy requirements. We have implemented a model-based approach to fault detection and isolation that does not require explicit characterization of failures prior to launch. It is thus able to detect failures that were not considered in the failure and effects analysis. We have applied this technique to several different subsystems and tested our approach against both simulations and an electrical power system hardware testbed. We present findings from simulation and hardware tests which demonstrate the ability of our model-based system to detect and isolate failures, and describe our work in porting the Ada version of this system to a flight-qualified processor. We also discuss current research aimed at expanding our system to monitor the entire spacecraft.

Necrotizing enterocolitis (NEC) remains one of the most common underlying diagnoses of short bowel syndrome (SBS) in children. The relationship between the etiology of SBS and ultimate enteral autonomy has not been well studied. This investigation sought to evaluate the rate of achievement of enteral autonomy in SBS patients with and without NEC. Following IRB approval, 109 patients (2002-2014) at a multidisciplinary intestinal rehabilitation program were reviewed. The primary outcome evaluated was achievement of enteral autonomy (i.e. fully weaning from parenteral nutrition). Patient demographics, primary diagnosis, residual small bowel length, percent expected small bowel length, median serum citrulline level, number of abdominal operations, status of the ileocecal valve (ICV), presence of ileostomy, liver function tests, and treatment for bacterial overgrowth were recorded for each patient. Median age at PN onset was 0 weeks [IQR 0-0]. Median residual small bowel length was 33.5 cm [IQR 20-70]. NEC was present in 37 of 109 (33.9%) of patients. 45 patients (41%) achieved enteral autonomy after a median PN duration of 15.3 [IQR 7.2-38.4]months. Overall, 64.9% of patients with NEC achieved enteral autonomy compared to 29.2% of patients with a different primary diagnosis (p=0.001, Fig. 1). Patients with NEC remained more likely than those without NEC to achieve enteral autonomy after two (45.5% vs. 12.0%) and four (35.7% vs. 6.3%) years on PN (Fig. 1). Logistic regression analysis demonstrated the following parameters as independent predictors of enteral autonomy: diagnosis of NEC (p<0.002), median serum citrulline level (p<0.02), absence of a jejunostomy or ileostomy (p=0.013), and percent expected small bowel length (p=0.005). Children with SBS because of NEC have a significantly higher likelihood of fully weaning from parenteral nutrition compared to children with other causes of SBS. Additionally, patients with NEC may attain enteral autonomy even after long durations of parenteral support. Copyright © 2016 Elsevier Inc. All rights reserved.

There has been limited research examining how organizational factors are associated with the level of confidence of residential aged care staff in managing both residents' depression and the behavioural and psychological symptoms of residents with dementia (BPSD). This study investigated this issue. A cross-sectional study design was employed. In total, 255 aged care staff (131 senior staff, 124 junior staff) from 21 residential care facilities participated in the study. All staff completed measures of self-efficacy in managing BPSD as well as confidence in working with older people with depression. They also completed measures of organizational climate (autonomy, cohesion, trust, pressure, support, recognition, fairness and encouragement of innovation) and measures of workplace experience (job role, number of years working in aged care facilities), job stress and satisfaction, and knowledge of depression. The results demonstrated that autonomy, trust, support, and job stress were associated with confidence in managing BPSD, while the factors related to confidence in managing depression were autonomy, support, job stress, job satisfaction, and knowledge of depression. These findings highlight that organizational climate factors need to be addressed in order to increase staff confidence in managing BPSD and depression. In particular, the findings demonstrate the importance of fostering organizational environments in which autonomy is promoted and there is support and cooperation among aged care staff. Attention to these factors is likely to increase the confidence of staff as they carry out their carer role.

As part of the NASA Systems Autonomy Demonstration Project, a thermal expert system (TEXSYS) is being developed. TEXSYS combines a fast real time control system, a sophisticated human interface for the user and several distinct artificial intelligence techniques in one system. TEXSYS is to provide real time control, operations advice and fault detection, isolation and recovery capabilities for the space station Thermal Test Bed (TTB). TEXSYS will be integrated with the TTB and act as an intelligent assistant to thermal engineers conducting TTB tests and experiments. The results are presented from connecting the real time controller to the knowledge based system thereby creating an integrated system. Special attention will be paid to the problem of filtering and interpreting the raw, real time data and placing the important values into the knowledge base of the expert system.

Pharmaceutical information systems and possible implementations of informed consent - developing an heuristic

PubMed Central

2012-01-01

Background Denmark has implemented a comprehensive, nationwide pharmaceutical information system, and this system has been evaluated by the Danish Council of Ethics. The system can be seen as an exemplar of a comprehensive health information system for clinical use. Analysis The paper analyses 1) how informed consent can be implemented in the system and how different implementations create different impacts on autonomy and control of information, and 2) arguments directed towards justifying not seeking informed consent in this context. Results and Conclusion Based on the analysis a heuristic is provided which enables a ranking and estimation of the impact on autonomy and control of information of different options for consent to entry of data into the system and use of data from the system. The danger of routinisation of consent is identified. The Danish pharmaceutical information system raises issues in relation to autonomy and control of information, issues that will also occur in relation to other similar comprehensive health information systems. Some of these issues are well understood and their impact can be judged using the heuristic which is provided. More research is, however needed in relation to routinisation of consent. PMID:23157854

Objective Longitudinal comparison of mother and adolescent agreement regarding decision-making autonomy for adolescents with and without spina bifida (SB). Methods Forty-two mother–adolescent dyads of adolescents with SB and 55 comparison dyads reported on who was responsible for decision-making across five waves of data collection, beginning at age 8 or 9 years through age 16 or 17 years. Results The proportion of tasks that dyads agreed were decided by adolescents increased over time for both samples beginning at age 12 or 13 years, but appeared to be delayed by roughly two years for youth with SB and was lower for youth with SB from lower socioeconomic (SES) backgrounds. Mothers and adolescents with low SES demonstrated higher proportions of tasks that dyads agreed were decided by mothers. Conclusions SB and low SES are risk factors for lower levels of agreed-upon decision-making autonomy. Future studies should examine how parent–adolescent agreement regarding autonomy relates to psychosocial outcomes. PMID:20943730

"I" Seek Autonomy, "We" Rely on Each Other: Self-Construal and Regulatory Focus as Determinants of Autonomy- and Dependency-Oriented Help-Seeking Behavior.

PubMed

Komissarouk, Svetlana; Nadler, Arie

2014-06-01

There are two typical approaches to requesting help: autonomy-oriented help-seeking (asking in order to learn how to fix a problem) versus dependency-oriented help-seeking (asking a helper to fix it). This article presents three studies demonstrating a systematic impact of a person's chronic or activated self-construal (interdependent vs. independent) that operates through activated regulatory focus (prevention vs. promotion) on these two help-seeking styles. The hypothesis was tested by measuring chronic self-construal, regulatory foci, and help-seeking styles (Study 3), and by priming self-construal (Study 1) and regulatory focus (Study 2). Results show that people with an independent self-construal and a promotion focus prefer autonomy-oriented help, whereas people with an interdependent self-construal and a prevention focus seek dependency-oriented help. Mediation analysis (Study 3) shows that regulatory focus is a mediator between self-construal and help-seeking styles. The conceptual and applied implications of these findings are discussed. © 2014 by the Society for Personality and Social Psychology, Inc.

Contextual predictability shapes signal autonomy.

PubMed

Winters, James; Kirby, Simon; Smith, Kenny

2018-07-01

Aligning on a shared system of communication requires senders and receivers reach a balance between simplicity, where there is a pressure for compressed representations, and informativeness, where there is a pressure to be communicatively functional. We investigate the extent to which these two pressures are governed by contextual predictability: the amount of contextual information that a sender can estimate, and therefore exploit, in conveying their intended meaning. In particular, we test the claim that contextual predictability is causally related to signal autonomy: the degree to which a signal can be interpreted in isolation, without recourse to contextual information. Using an asymmetric communication game, where senders and receivers are assigned fixed roles, we manipulate two aspects of the referential context: (i) whether or not a sender shares access to the immediate contextual information used by the receiver in interpreting their utterance; (ii) the extent to which the relevant solution in the immediate referential context is generalisable to the aggregate set of contexts. Our results demonstrate that contextual predictability shapes the degree of signal autonomy: when the context is highly predictable (i.e., the sender has access to the context in which their utterances will be interpreted, and the semantic dimension which discriminates between meanings in context is consistent across communicative episodes), languages develop which rely heavily on the context to reduce uncertainty about the intended meaning. When the context is less predictable, senders favour systems composed of autonomous signals, where all potentially relevant semantic dimensions are explicitly encoded. Taken together, these results suggest that our pragmatic faculty, and how it integrates information from the context in reducing uncertainty, plays a central role in shaping language structure.

Distributed intelligence for ground/space systems

1994-01-01

DI is short for Distributed Intelligence for Ground/Space Systems and the DI Study is one in a series of ESA projects concerned with the development of new concepts and architectures for future autonomous spacecraft systems. The kick-off of DI was in January 1994 and the planned duration is three years. The background of DI is the desire to design future ground/space systems with a higher degree of autonomy than seen in today's missions. The aim of introducing autonomy in spacecraft systems is to: (1) lift the role of the spacecraft operators from routine work and basic troubleshooting to supervision; (2) ease access to and increase availability of spacecraft resources; (3) carry out basic mission planning for users; (4) enable missions which have not yet been feasible due to eg. propagation delays, insufficient ground station coverage etc.; and (5) possibly reduce mission cost. The study serves to identify the feasibility of using state-of-the-art technologies in the area of planning, scheduling, fault detection using model-based diagnosis and knowledge processing to obtain a higher level of autonomy in ground/space systems.

The secret art of managing healthcare expenses: investigating implicit rationing and autonomy in public healthcare systems.

PubMed

Lauridsen, S M R; Norup, M S; Rossel, P J H

2007-12-01

Rationing healthcare is a difficult task, which includes preventing patients from accessing potentially beneficial treatments. Proponents of implicit rationing argue that politicians cannot resist pressure from strong patient groups for treatments and conclude that physicians should ration without informing patients or the public. The authors subdivide this specific programme of implicit rationing, or "hidden rationing", into local hidden rationing, unsophisticated global hidden rationing and sophisticated global hidden rationing. They evaluate the appropriateness of these methods of rationing from the perspectives of individual and political autonomy and conclude that local hidden rationing and unsophisticated global hidden rationing clearly violate patients' individual autonomy, that is, their right to participate in medical decision-making. While sophisticated global hidden rationing avoids this charge, the authors point out that it nonetheless violates the political autonomy of patients, that is, their right to engage in public affairs as citizens. A defence of any of the forms of hidden rationing is therefore considered to be incompatible with a defence of autonomy.

Care, Autonomy, and Gender in Nursing Practice: A Historical Study of Nurses' Experiences.

PubMed

Galbany-Estragués, Paola; Comas-d'Argemir, Dolors

2017-10-01

Care is the essence of the nursing role and is closely related to the concept of professional autonomy. Autonomy is implicated in power relations between doctors and nurses and between men and women. These relationships are closely linked to care practices and the inequality of nursing and medicine. The aim of this study was to analyze nursing discourse regarding the concept of care and its relationship to the concept of autonomy and gender. This is a historical study based on oral interviews that took place between November 2008 and February 2011. We interviewed 19 nursing professionals who currently worked at the Hospital of the Holy Spirit (near Barcelona) or had worked there between 1961 and 2010. Semistructured interviews were recorded, transcribed, and analyzed. We highlight four main themes: "a real nurse"; "more technology, less care"; "the fragility of autonomy"; and "the invisibility of nursing work." These themes show the contradictions in the nursing profession that are based on the concept of care. However, in daily practice, the concept of care varies. Time pressure distances the nursing practice from its theoretical context. Changes in the concept of care are related to transformations in the health system and nursing work. Changes related to the autonomy of nursing are related to changes in the concept of care. In practice, care has a biomedical orientation. Care has become technologized and bureaucratized, which reduces the time that is spent with the patient. In a context in which medical authority predominates, nursing's struggle for autonomy is based on the recognition of the value of care. When care becomes invisible, the autonomy of nursing as a profession is threatened. This conclusion allows reflections about shifts in the concept of care and how they affect clinical practice and the autonomy of the nursing profession.

AMO EXPRESS: A Command and Control Experiment for Crew Autonomy

NASA is investigating a range of future human spaceflight missions, including both Mars-distance and Near Earth Object (NEO) targets. Of significant importance for these missions is the balance between crew autonomy and vehicle automation. As distance from Earth results in increasing communication delays, future crews need both the capability and authority to independently make decisions. However, small crews cannot take on all functions performed by ground today, and so vehicles must be more automated to reduce the crew workload for such missions. NASA's Advanced Exploration Systems Program funded Autonomous Mission Operations (AMO) project conducted an autonomous command and control demonstration of intelligent procedures to automatically initialize a rack onboard the International Space Station (ISS) with power and thermal interfaces, and involving core and payload command and telemetry processing, without support from ground controllers. This autonomous operations capability is enabling in scenarios such as a crew medical emergency, and representative of other spacecraft autonomy challenges. The experiment was conducted using the Expedite the Processing of Experiments for Space Station (EXPRESS) rack 7, which was located in the Port 2 location within the U.S Laboratory onboard the International Space Station (ISS). Activation and deactivation of this facility is time consuming and operationally intensive, requiring coordination of three flight control positions, 47 nominal steps, 57 commands, 276 telemetry checks, and coordination of multiple ISS systems (both core and payload). The autonomous operations concept includes a reduction of the amount of data a crew operator is required to verify during activation or de-activation, as well as integration of procedure execution status and relevant data in a single integrated display. During execution, the auto-procedures provide a step-by-step messaging paradigm and a high level status upon termination. This messaging and high level status is the only data generated for operator display. To enhance situational awareness of the operator, the Web-based Procedure Display (WebPD) provides a novel approach to the issues of procedure display and execution tracking. For this demonstration, the procedure was initiated and monitored from the ground. As the Timeliner sequences executed, their high level execution status was transmitted to ground, for WebPD consumption.

In addition to the conventional uses of tele-operated robots for unexploded ordinance handling and disposal, water cannons and other crowd control devices, robots can also be employed for a host of terrorism deterrence and detection applications. In previous research USU developed a completely autonomous prototype robot for performing under- vehicle inspections in parking areas (ODIS). Testing of this prototype and discussions with the user community indicated that neither the technology nor the users are ready for complete autonomy. In this paper we present a robotic system based on ODIS that balances the users' desire/need for tele- operation with a limited level of autonomy that enhances the performance of the robot. The system can be used by both civilian law enforcement and military police to replace the traditional mirror on a stick system of looking under cars for bombs and contraband.

Integrating intrinsic mobility into unmanned ground vehicle systems

Brosinsky, Chris A.; Penzes, Steven G.; Buehler, Martin G.; Steeves, Carl

2001-09-01

The ability of an Unmanned Ground Vehicle (UGV) to successfully move about in its environment is enabled by the synergistic combination of perception, control and platform (mobility and utility). Vast effort is being expended on the former technologies but little demonstrable evidence has been produced to indicate that the latter (mobility/utility) has been considered as an integral part of the UGV systems level capability; a concept commonly referred to as intrinsic mobility. While past work described the rationale for hybrid locomotion, this paper aims to demonstrate that integrating intrinsic mobility into a UGV systems mobility element or 'vehicle' will be a key contributor to the magnitude of autonomy that the system can achieve. This paper serves to provide compelling evidence that 1) intrinsic mobility improvements provided by hybrid locomotion configurations offer the best generic mobility, that 2) strict attention must be placed on the optimization of both utility (inherent vehicle capabilities) and mobility and that 3) the establishment of measures of performance for unmanned vehicle mobility is an unmet and latent need.

This paper presents an algorithm and a system for vertical infrastructure inspection using a vertical take-off and landing (VTOL) unmanned aerial vehicle and shared autonomy. Inspecting vertical structures such as light and power distribution poles is a difficult task that is time-consuming, dangerous and expensive. Recently, micro VTOL platforms (i.e., quad-, hexa- and octa-rotors) have been rapidly gaining interest in research, military and even public domains. The unmanned, low-cost and VTOL properties of these platforms make them ideal for situations where inspection would otherwise be time-consuming and/or hazardous to humans. There are, however, challenges involved with developing such an inspection system, for example flying in close proximity to a target while maintaining a fixed stand-off distance from it, being immune to wind gusts and exchanging useful information with the remote user. To overcome these challenges, we require accurate and high-update rate state estimation and high performance controllers to be implemented onboard the vehicle. Ease of control and a live video feed are required for the human operator. We demonstrate a VTOL platform that can operate at close-quarters, whilst maintaining a safe stand-off distance and rejecting environmental disturbances. Two approaches are presented: Position-Based Visual Servoing (PBVS) using an Extended Kalman Filter (EKF) and estimator-free Image-Based Visual Servoing (IBVS). Both use monocular visual, inertia, and sonar data, allowing the approaches to be applied for indoor or GPS-impaired environments. We extensively compare the performances of PBVS and IBVS in terms of accuracy, robustness and computational costs. Results from simulations and indoor/outdoor (day and night) flight experiments demonstrate the system is able to successfully inspect and circumnavigate a vertical pole. PMID:26340631

Robotic intelligence kernel

Bruemmer, David J [Idaho Falls, ID

2009-11-17

A robot platform includes perceptors, locomotors, and a system controller. The system controller executes a robot intelligence kernel (RIK) that includes a multi-level architecture and a dynamic autonomy structure. The multi-level architecture includes a robot behavior level for defining robot behaviors, that incorporate robot attributes and a cognitive level for defining conduct modules that blend an adaptive interaction between predefined decision functions and the robot behaviors. The dynamic autonomy structure is configured for modifying a transaction capacity between an operator intervention and a robot initiative and may include multiple levels with at least a teleoperation mode configured to maximize the operator intervention and minimize the robot initiative and an autonomous mode configured to minimize the operator intervention and maximize the robot initiative. Within the RIK at least the cognitive level includes the dynamic autonomy structure.

2016-10-01

Closed-loop medical devices such as brain-computer interfaces are an emerging and rapidly advancing neurotechnology. The target patients for brain-computer interfaces (BCIs) are often severely paralyzed, and thus particularly vulnerable in terms of personal autonomy, decisionmaking capacity, and agency. Here we analyze the effects of closed-loop medical devices on the autonomy and accountability of both persons (as patients or research participants) and neurotechnological closed-loop medical systems. We show that although BCIs can strengthen patient autonomy by preserving or restoring communicative abilities and/or motor control, closed-loop devices may also create challenges for moral and legal accountability. We advocate the development of a comprehensive ethical and legal framework to address the challenges of emerging closed-loop neurotechnologies like BCIs and stress the centrality of informed consent and refusal as a means to foster accountability. We propose the creation of an international neuroethics task force with members from medical neuroscience, neuroengineering, computer science, medical law, and medical ethics, as well as representatives of patient advocacy groups and the public.

2010-11-01

This study aimed to investigate characteristics of Brazilian mothers' beliefs system, in the dimensions of autonomy and interdependence. A group of 600 women, half from state capitals and half from small towns, participated in the study. They were individually interviewed with Scales of Allocentrism, Beliefs about Parental Practices and Socialization Goals. Paired and Independent samples t tests and Multivariate GLM were performed. The results indicate that although mothers from both contexts value autonomy, mothers inhabiting small towns considered the relational dimension as the most important; whereas mothers inhabiting capitals valued equally both dimensions, either in their beliefs about practices or in the socialization goals for their children. Mothers from small towns have a higher mean score for allocentrism than mothers living in capitals. Thus, place of residence proved to be a relevant variable in the modulation of maternal beliefs. Educational level was not a significant factor in the variables considered and with this group of mothers. The study results are discussed in terms of their contribution to the understanding of the complex relationship between dimensions of autonomy and interdependence in mothers' beliefs system.

2012-01-01

Recently, numerous systems for geo-tracking Alzheimer's patients with dementia have been developed and reported to be functional for the purposes of security and data collection. However, studies stated possible loss of freedom and autonomy for patients, along with violations of their privacy, which may lead to loss of prestige/dignity. In this study, a geotracking system that aims to balance patients' security and their need for privacy and autonomy is proposed. The system introduces a personalized, four-level temporal geofence based tracking, warning and notification protocol that incorporates a safety check mechanism operating over Global System for Mobile Communications network.

Psychological autonomy and hierarchical relatedness as organizers of developmental pathways

PubMed Central

Keller, Heidi

2016-01-01

The definition of self and others can be regarded as embodying the two dimensions of autonomy and relatedness. Autonomy and relatedness are two basic human needs and cultural constructs at the same time. This implies that they may be differently defined yet remain equally important. The respective understanding of autonomy and relatedness is socialized during the everyday experiences of daily life routines from birth on. In this paper, two developmental pathways are portrayed that emphasize different conceptions of autonomy and relatedness that are adaptive in two different environmental contexts with very different affordances and constraints. Western middle-class children are socialized towards psychological autonomy, i.e. the primacy of own intentions, wishes, individual preferences and emotions affording a definition of relatedness as psychological negotiable construct. Non-Western subsistence farmer children are socialized towards hierarchical relatedness, i.e. positioning oneself into the hierarchical structure of a communal system affording a definition of autonomy as action oriented, based on responsibility and obligations. Infancy can be regarded as a cultural lens through which to study the different socialization agendas. Parenting strategies that aim at supporting these different socialization goals in German and Euro-American parents on the one hand and Nso farmers from North Western Cameroon on the other hand are described. It is concluded that different pathways need to be considered in order to understand human psychology from a global perspective. PMID:26644589

Inflexible work schedules affect job satisfaction and influence nurse turnover. Job satisfaction is a significant predictor of nurse retention. Acute care hospitals report that job satisfaction is influenced by autonomy and educational opportunity. This project discusses implementation of computer-based self-scheduling in a hospital system and its impact. It is important for staff development educators to be aware that self-scheduling may play a key role in autonomy, professional development, turnover, and hospital costs.

The gender gap in education in favour of girls is a widely known phenomenon. Boys generally have higher dropout rates, obtain lower grades, and show lower engagement. Insight into factors related to these academic outcomes could help to address the gender gap. This study investigated, for Dutch language classes, (1) how boys and girls differ in behavioural engagement, (2) which teacher support dimensions (autonomy support, structure, involvement) may explain gender differences in engagement (mediation hypothesis), and (3) whether and which of these teacher support dimensions matter more for boys' as opposed to girls' engagement (moderation or differential effects hypothesis). A total of 385 Grade 7 students and their 15 language teachers participated in this study. Teacher support was assessed through student reports. Student engagement was measured using student, teacher, and observer reports. By means of structural equation modelling, the mediating role of the teacher support dimensions for gender differences in behavioural engagement was tested. The potential differential role of the teacher support dimensions for boys' and girls' engagement was investigated through multigroup analysis. Boys were less engaged than girls and reported lower support from their teacher. Autonomy support and involvement partially mediated the relationship between gender and behavioural engagement. Autonomy support was demonstrated to be a protective factor for boys' engagement but not for girls'. Structure and involvement contributed equally to engagement for both sexes. Although involvement and autonomy support partly explained the gender gap in engagement (mediation hypothesis), more support was found for differential effects of autonomy support on boys' versus girls' engagement (differential effects hypothesis). © 2015 The British Psychological Society.

Student engagement is an important contributor to school success, yet high school students routinely describe themselves as disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement. This study investigated students’ perceptions of autonomy, teacher connection, and academic competence as predictors of changes in student engagement within the classroom from the start to the end of a course. Participants were 578 (58% female) diverse (67.8% White, 25.2% African American, 5.1% Hispanic, 1.2% Asian American) high school students from 34 classrooms who provided questionnaire data both at the start and the end of a single course. Novel results from a cross-lagged model demonstrated that students who perceived their classrooms as allowing and encouraging their own autonomy in the first few weeks increased their engagement throughout the course, rather than the typical decline in engagement that was demonstrated by students in other classrooms. This finding is unique in that it extended to both students’ perceptions of engagement and observations of student engagement, suggesting a fairly robust pattern. The pertinence of this finding to adolescent developmental needs and its relationship to educational practice is discussed. PMID:22198156

American Indians (AI) have a high prevalence of electronic nicotine delivery system (ENDS) use. However, little information exists on (ENDS) use, either alone or in combination with cigarettes (dual use), among AI. The objective of this small-scaled study was to examine use behaviours and dependence among exclusive ENDS users and dual users of AI descent. Exclusive smokers were included for comparison purposes. Oklahoma, USA. Adults of AI descent who reported being exclusive ENDS users (n=27), dual users (n=28) or exclusive cigarette smokers (n=27). Participants completed a detailed questionnaire on use behaviours. The Hooked on Nicotine Checklist (HONC) was used to assess loss of autonomy over cigarettes and was reworded for ENDS. Dual users completed the HONC twice. Sum of endorsed items indicated severity of diminished autonomy. Comparisons were made with non-parametric methods and statistical significance was defined as P<0.05. Median duration of ENDS use was 2 years among ENDS users and 1 year among dual users. Most ENDS and dual users reported <20 vape sessions per day (72.0% vs 72.0%) with ≤10 puffs per vape session (70.4% vs 69.2%). Severity of diminished autonomy over ENDS was similar among ENDS and dual users (medians: 4 vs 3; P=0.6865). Among dual users, severity of diminished autonomy was lower for ENDS than cigarettes (medians: 3 vs 9; P=<0.0001). Comparing ENDS users with smokers, ENDS users had a lower severity of diminished autonomy (4 vs 8; P=0.0077). Comparing dual users with smokers, median severity of diminished autonomy over cigarettes did not differ (P=0.6865). Severity of diminished autonomy was lower for ENDS than cigarettes in this small sample of AI. Future, adequately powered studies should be conducted to fully understand ENDS use patterns and dependence levels in this population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The Jade File System. Ph.D. Thesis

Rao, Herman Chung-Hwa

1991-01-01

File systems have long been the most important and most widely used form of shared permanent storage. File systems in traditional time-sharing systems, such as Unix, support a coherent sharing model for multiple users. Distributed file systems implement this sharing model in local area networks. However, most distributed file systems fail to scale from local area networks to an internet. Four characteristics of scalability were recognized: size, wide area, autonomy, and heterogeneity. Owing to size and wide area, techniques such as broadcasting, central control, and central resources, which are widely adopted by local area network file systems, are not adequate for an internet file system. An internet file system must also support the notion of autonomy because an internet is made up by a collection of independent organizations. Finally, heterogeneity is the nature of an internet file system, not only because of its size, but also because of the autonomy of the organizations in an internet. The Jade File System, which provides a uniform way to name and access files in the internet environment, is presented. Jade is a logical system that integrates a heterogeneous collection of existing file systems, where heterogeneous means that the underlying file systems support different file access protocols. Because of autonomy, Jade is designed under the restriction that the underlying file systems may not be modified. In order to avoid the complexity of maintaining an internet-wide, global name space, Jade permits each user to define a private name space. In Jade's design, we pay careful attention to avoiding unnecessary network messages between clients and file servers in order to achieve acceptable performance. Jade's name space supports two novel features: (1) it allows multiple file systems to be mounted under one direction; and (2) it permits one logical name space to mount other logical name spaces. A prototype of Jade was implemented to examine and validate its design. The prototype consists of interfaces to the Unix File System, the Sun Network File System, and the File Transfer Protocol.

This presentation goes over the work we have performed over the last few years on verification and validation of the next generation onboard collision avoidance system, ACAS X, for commercial aircraft. It describes our work on probabilistic verification and synthesis of the model that ACAS X is based on, and goes on to the validation of that model with respect to actual simulation and flight data. The presentation then moves on to identify the characteristics of ACAS X that are related to autonomy and to discuss the challenges that autonomy pauses on VV. All work presented has already been published.

A Facility and Architecture for Autonomy Research

Autonomy is a key enabling factor in the advancement of the remote robotic exploration. There is currently a large gap between autonomy software at the research level and software that is ready for insertion into near-term space missions. The Mission Simulation Facility (MST) will bridge this gap by providing a simulation framework and suite of simulation tools to support research in autonomy for remote exploration. This system will allow developers of autonomy software to test their models in a high-fidelity simulation and evaluate their system's performance against a set of integrated, standardized simulations. The Mission Simulation ToolKit (MST) uses a distributed architecture with a communication layer that is built on top of the standardized High Level Architecture (HLA). This architecture enables the use of existing high fidelity models, allows mixing simulation components from various computing platforms and enforces the use of a standardized high-level interface among components. The components needed to achieve a realistic simulation can be grouped into four categories: environment generation (terrain, environmental features), robotic platform behavior (robot dynamics), instrument models (camera/spectrometer/etc.), and data analysis. The MST will provide basic components in these areas but allows users to plug-in easily any refined model by means of a communication protocol. Finally, a description file defines the robot and environment parameters for easy configuration and ensures that all the simulation models share the same information.

Frailty's Place in Ethics and Law: Some Thoughts on Equality and Autonomy and on Limits and Possibilities for Aging Citizens.

PubMed

McNally, Mary; Lahey, William

2015-01-01

Consideration of ethical and legal themes relating to frailty must engage with the concern that frailty is a pejorative concept that validates and reinforces the disadvantage and vulnerability of aging adults. In this chapter, we consider whether a greater focus on frailty may indeed be part of the solution to the disadvantages that aging adults face in achieving equality and maintaining their autonomy within systems that have used their frailty to deny them equality and autonomy. First, by examining equality both as an ethical norm and as a requirement for protections against discrimination, we raise questions about the grounds on which health providers and health systems can be required to give equal concern and respect to the needs of frail older persons. Second, we explore autonomy and identify the tension between meaningful self-determination and prevailing ethical and legal norms associated with informed choice. Third, we argue that a proper understanding of frailty is essential within both of these themes; it respects equality by enabling health providers and systems to identify and address the distinct care needs of aging adults and helps to align informed choice theory with appropriate processes for decision-making about those needs. 2015 S.

From 'automation' to 'autonomy': the importance of trust repair in human-machine interaction.

de Visser, Ewart J; Pak, Richard; Shaw, Tyler H

2018-04-09

Modern interactions with technology are increasingly moving away from simple human use of computers as tools to the establishment of human relationships with autonomous entities that carry out actions on our behalf. In a recent commentary, Peter Hancock issued a stark warning to the field of human factors that attention must be focused on the appropriate design of a new class of technology: highly autonomous systems. In this article, we heed the warning and propose a human-centred approach directly aimed at ensuring that future human-autonomy interactions remain focused on the user's needs and preferences. By adapting literature from industrial psychology, we propose a framework to infuse a unique human-like ability, building and actively repairing trust, into autonomous systems. We conclude by proposing a model to guide the design of future autonomy and a research agenda to explore current challenges in repairing trust between humans and autonomous systems. Practitioner Summary: This paper is a call to practitioners to re-cast our connection to technology as akin to a relationship between two humans rather than between a human and their tools. To that end, designing autonomy with trust repair abilities will ensure future technology maintains and repairs relationships with their human partners.

The question of autonomy in maternal health in Africa: a rights-based consideration.

PubMed

Amzat, Jimoh

2015-06-01

Maternal mortality is still very high in Africa, despite progress in control efforts at the global level. One elemental link is the question of autonomy in maternal health, especially at the household level where intrinsic human rights are undermined. A rights-based consideration in bioethics is an approach that holds the centrality of the human person, with a compelling reference to the fundamental human rights of every person. A philosophical and sociological engagement of gender and the notion of autonomy within the household reveals some fundamental rights-based perplexities for bioethical considerations in maternal health. The right to self-determination is undermined, and therefore women's dignity, freedom and autonomy, capacities, and choices are easily defiled. This study applies a rights-based approach to maternal health and demonstrates how rights concerns are associated with negative outcomes in maternal health in Africa. The discussion is situated at the household level, which is the starting point in health care. The paper submits that beyond legal and political rights within the context of the state, rights-based issues manifest at the household level. Many of those rights issues, especially relating to women's autonomy, are detrimental to maternal health in Africa. Therefore, a rights-based approach in the social construction of maternal health realities will contribute to alleviating the burden of maternal mortality in Africa.

Notes on patients with disabilities autonomy in Spanish law.

The U.N. Convention on the Rights of Persons with Disabilities recognizes as the first of its general principles the "Respect for inherent dignity, individual autonomy including the freedom to make one's own choice, and independence of persons" (Art.3.a). With regard to health, States Parties recognize that persons with disabilities have the right to the enjoyment of the highest attainable standard of health without being discriminated on the basis of disability (Article 25), which includes requiring health professionals to provide care of the same quality to persons with disabilities as to others, including on the basis of free and informed consent (subsection d).These guidelines must enlighten the interpretation of the Spanish legal system as for the scope of autonomy of people with disabilities. Nevertheless, they still bear some handicaps in order to preserve their autonomy from third-party interferences.

Previous studies on the relation between testosterone (T) levels and parenting have found ample evidence for the challenge hypothesis, demonstrating that high T levels inhibit parental involvement and that becoming a parent is related to a decrease in T levels in both mothers and fathers. However, less is known about the relation between T levels and more qualitative aspects of parenting. In the current study we examined basal T levels and diurnal variability in T levels in relation to mothers' and fathers' parenting quality. Participants included 217 fathers and 124 mothers with two children (3 and 5years of age). Evening and morning salivary T samples were analyzed with radio-immunoassays to determine circulating T levels. Parental sensitivity (i.e., child-centered responsiveness) and respect for children's autonomy were observed during free play in the family home. The results showed that higher evening T levels in mothers were associated with more sensitivity to the oldest and youngest child. Diurnal T variability was more consistently associated with parenting behavior towards their children than basal T levels. For fathers, more diurnal variability in T was associated with more sensitivity and more respect for autonomy with their youngest children. For mothers, more diurnal variability in T was associated with less sensitivity to both children and less respect for the youngest child's autonomy. These findings suggest that the T system might act differently in relation to parenting behavior in males and females. Copyright © 2016 Elsevier Inc. All rights reserved.

Under the Advanced Development Program for Space Station, Marshall Space Flight Center has been developing advanced automation applications for the Power Management and Distribution (PMAD) system inside the Space Station modules for the past three years. The Space Station Module Power Management and Distribution System (SSM/PMAD) test bed features three artificial intelligence (AI) systems coupled with conventional automation software functioning in an autonomous or closed-loop fashion. The AI systems in the test bed include a baseline scheduler/dynamic rescheduler (LES), a load shedding management system (LPLMS), and a fault recovery and management expert system (FRAMES). This test bed will be part of the NASA Systems Autonomy Demonstration for 1990 featuring cooperating expert systems in various Space Station subsystem test beds. It is concluded that advanced automation technology involving AI approaches is sufficiently mature to begin applying the technology to current and planned spacecraft applications including the Space Station.

This report summarizes the results of doctoral research that explored the cost impact of acquiring complex government systems jointly. The report begins by reviewing recent evidence that suggests that joint programs experience greater cost growth than non-joint programs. It continues by proposing an alternative approach for studying cost growth on government acquisition programs and demonstrates the utility of this approach by applying it to study the cost of jointness on three past programs that developed environmental monitoring systems for low-Earth orbit. Ultimately, the report concludes that joint programs' costs grow when the collaborating government agencies take action to retain ormore » regain their autonomy. The report provides detailed qualitative and quantitative data in support of this conclusion and generalizes its findings to other joint programs that were not explicitly studied here. Finally, it concludes by presenting a quantitative model that assesses the cost impacts of jointness and by demonstrating how government agencies can more effectively architect joint programs in the future.« less

Mild Normobaric Hypoxia Exposure for Human-Autonomy System Testing

Stephens, Chad L.; Kennedy, Kellie D.; Crook, Brenda L.; Williams, Ralph A.; Schutte, Paul

2017-01-01

An experiment investigated the impact of normobaric hypoxia induction on aircraft pilot performance to specifically evaluate the use of hypoxia as a method to induce mild cognitive impairment to explore human-autonomous systems integration opportunities. Results of this exploratory study show that the effect of 15,000 feet simulated altitude did not induce cognitive deficits as indicated by performance on written, computer-based, or simulated flight tasks. However, the subjective data demonstrated increased effort by the human test subject pilots to maintain equivalent performance in a flight simulation task. This study represents current research intended to add to the current knowledge of performance decrement and pilot workload assessment to improve automation support and increase aviation safety.

Procedural Learning and Memory Rehabilitation in Korsakoff's Syndrome - a Review of the Literature.

PubMed

Oudman, Erik; Nijboer, Tanja C W; Postma, Albert; Wijnia, Jan W; Van der Stigchel, Stefan

2015-06-01

Korsakoff's syndrome (KS) is a chronic neuropsychiatric disorder caused by alcohol abuse and thiamine deficiency. Patients with KS show restricted autonomy due to their severe declarative amnesia and executive disorders. Recently, it has been suggested that procedural learning and memory are relatively preserved in KS and can effectively support autonomy in KS. In the present review we describe the available evidence on procedural learning and memory in KS and highlight advances in memory rehabilitation that have been demonstrated to support procedural memory. The specific purpose of this review was to increase insights in the available tools for successful memory rehabilitation and give suggestions how to apply these tools in clinical practice to increase procedural learning in KS. Current evidence suggests that when memory rehabilitation is adjusted to the specific needs of KS patients, this will increase their ability to learn procedures and their typically compromised autonomy gets enhanced.

Is Payment a Benefit?

PubMed Central

Wertheimer, Alan

2011-01-01

What I call “the standard view” claims that IRBs should not regard financial payment as a benefit to subjects for the purpose of risk/benefit assessment. Although the standard view is universally accepted, there is little defense of that view in the canonical documents of research ethics or the scholarly literature. This article claims that insofar as IRBs should be concerned with the interests and autonomy of research subjects, they should reject the standard view and adopt “the incorporation view.” The incorporation view is more consistent with the underlying soft-paternalist justification for risk-benefit assessment and demonstrates respect for the autonomy of prospective subjects. Adoption of the standard view precludes protocols that advance the interests of subjects, investigators, and society. After considering several objections to the argument, I consider several arguments for the standard view that do not appeal to the interests and autonomy of research subjects. PMID:21726261

Parenting and adolescent self-regulation.

PubMed

Purdie, Nola; Carroll, Annemaree; Roche, Lawrence

2004-12-01

This study examined the relationship between adolescents' academic and non-academic self-regulation (SR), authoritative parenting (as demonstrated by high levels of Involvement, Strictness, and Autonomy Granting), and parent self-efficacy in four areas. Participants were 214 Australian high school students and their parents. There was a moderate correlation (r = 0.63) between academic and non-academic SR. Adolescents and their parents differed significantly in their perceptions of parenting behaviours, with parents rating themselves higher than their children on Involvement, Autonomy Granting, and Strictness behaviours. A model of the relationships between the constructs was developed showing a strong path from parent self-efficacy to both academic and non-academic SR via high parental Involvement (as perceived by adolescents). Strict parenting and the granting by parents of psychological autonomy to their adolescent children did not appear to be important in the development of young people's self-regulatory behaviours.

To investigate factors associated with self-reported pregnancy termination in Ghana and thereby appreciate the correlates of abortion-seeking in order to understand safe abortion care provision. In a retrospective study, data from the Ghana 2008 Demographic and Health Survey were used to investigate factors associated with self-reported pregnancy termination. Variables on an individual and household level were examined by both bivariate analyses and multivariate logistic regression. A five-point autonomy scale was created to explore the role of female autonomy in reported abortion-seeking behavior. Among 4916 women included in the survey, 791 (16.1%) reported having an abortion. Factors associated with abortion-seeking included being older, having attended school, and living in an urban versus a rural area. When entered into a logistic regression model with demographic control variables, every step up the autonomy scale (i.e. increasing autonomy) was associated with a 14.0% increased likelihood of reporting the termination of a pregnancy (P < 0.05). Although health system barriers might play a role in preventing women from seeking safe abortion services, autonomy on an individual level is also important and needs to be addressed if women are to be empowered to seek safe abortion services.

Expanding role for autonomy in military space

NASA Technical Reports Server (NTRS)

Evans, D. D.; Gajewski, R. R.

1985-01-01

The Jet Propulsion Laboratory is currently transferring satellite on-board autonomy technology to the USAF for use in military spacecraft as a means of lowering the ground support requirements. The techniques were proven on the Viking and Voyager spacecraft and permitted on-board fault detection and correction. New military satellites will incorporate an autonomous redundancy and maintenance management subsystem in an on-board computer, while the system will still be subject to ground-based safing commands for situations demanding deeper analyses. A level 5 autonomy will need 256 kb memory, 10 Mb nonvolatile data storage and 50 W power and will weigh 20 kg. Systems will be periodically checked and compared with an ideal in the data base. Deviations detected will result in a rollback and redundant examination by two microprocessors, which can initiate correction commands until operational criteria are met. The development of the expert systems to the point that they satisfy military specifications is expected to take 10 yr.

Mobile systems exploring Planetary surfaces in future will require more autonomy than today. The EU FP7-SPACE Project ProViScout (2010-2012) establishes the building blocks of such autonomous exploration systems in terms of robotics vision by a decision-based combination of navigation and scientific target selection, and integrates them into a framework ready for and exposed to field demonstration. The PRoViScout on-board system consists of mission management components such as an Executive, a Mars Mission On-Board Planner and Scheduler, a Science Assessment Module, and Navigation & Vision Processing modules. The platform hardware consists of the rover with the sensors and pointing devices. We report on the major building blocks and their functions & interfaces, emphasizing on the computer vision parts such as image acquisition (using a novel zoomed 3D-Time-of-Flight & RGB camera), mapping from 3D-TOF data, panoramic image & stereo reconstruction, hazard and slope maps, visual odometry and the recognition of potential scientifically interesting targets.

A Feasible Approach for Implementing Greater Levels of Satellite Autonomy

NASA Astrophysics Data System (ADS)

Lindsay, Steve; Zetocha, Paul

2002-01-01

In this paper, we propose a means for achieving increasingly autonomous satellite operations. We begin with a brief discussion of the current state-of-the-art in satellite ground operations and flight software, as well as the real and perceived technical and political obstacles to increasing the levels of autonomy on today's satellites. We then present a list of system requirements that address these hindrances and include the artificial intelligence (AI) technologies with the potential to satisfy these requirements. We conclude with a discussion of how the space industry can use this information to incorporate increased autonomy. From past experience we know that autonomy will not just "happen," and we know that the expensive course of manually intensive operations simply cannot continue. Our goal is to present the aerospace industry with an analysis that will begin moving us in the direction of autonomous operations.

[Autonomy and health needs in the systematization of nursing assistance under the optics of the primary care].

Barros, Débora Gomes; Chiesa, Anna Maria

2007-12-01

Given recent changes in the organization of the primary health care in Brazil, it is necessary to reflect on the contributions of nursing care. This article aims to review the concepts of autonomy and health needs and its applications in different proposals for the systematization of the nursing care. It is a literature review on systematization of the nursing assistance, autonomy and health needs in databases LILACS and BDENF. The most relevant results indicate that autonomy incorporates aspects professional and patient's that are sustained by their respective categories. About needs we found that tracks biological needs and social needs, which intersect with the psychological to cover biopsychosocial needs. It was found that the application of the concepts was not present in classification systems of nursing. However, they were more related to International Classification of Nursing Practice (ICNP) and International Classification of Nursing Practice in Collective Heath (ICNPCH) projects.

Autonomous technology - sources of confusion: a model for explanation and prediction of conceptual shifts.

PubMed

Stensson, Patrik; Jansson, Anders

2014-01-01

Today, autonomous is often used for technology with a more intelligent self-management capability than common automation. This concept usage is maladaptive, ignoring both the distinction between autonomy and heteronomy according to Kant's categorical imperative and that the meaning of autonomy implies qualities technology cannot have. Being autonomous is about having the right to be wrong, a right justified by accountability and insightful understanding of real-life values, and it is about being externally uncontrollable. The contemporary use of autonomy as well as similar concepts is discussed and a model is presented showing how six sources of confusion interact in a vicious circle that impede human authority and autonomy. Our goal is to sort out these confusions and contribute to a development in which the different roles of machines and people, and human responsibilities, are explicated rather than blurred, which should facilitate the forming of truly beneficial and complementary systems.

Development of an unmanned maritime system reference architecture

NASA Astrophysics Data System (ADS)

Duarte, Christiane N.; Cramer, Megan A.; Stack, Jason R.

2014-06-01

The concept of operations (CONOPS) for unmanned maritime systems (UMS) continues to envision systems that are multi-mission, re-configurable and capable of acceptable performance over a wide range of environmental and contextual variability. Key enablers for these concepts of operation are an autonomy module which can execute different mission directives and a mission payload consisting of re-configurable sensor or effector suites. This level of modularity in mission payloads enables affordability, flexibility (i.e., more capability with future platforms) and scalability (i.e., force multiplication). The modularity in autonomy facilitates rapid technology integration, prototyping, testing and leveraging of state-of-the-art advances in autonomy research. Capability drivers imply a requirement to maintain an open architecture design for both research and acquisition programs. As the maritime platforms become more stable in their design (e.g. unmanned surface vehicles, unmanned underwater vehicles) future developments are able to focus on more capable sensors and more robust autonomy algorithms. To respond to Fleet needs, given an evolving threat, programs will want to interchange the latest sensor or a new and improved algorithm in a cost effective and efficient manner. In order to make this possible, the programs need a reference architecture that will define for technology providers where their piece fits and how to successfully integrate. With these concerns in mind, the US Navy established the Unmanned Maritime Systems Reference Architecture (UMS-RA) Working Group in August 2011. This group consists of Department of Defense and industry participants working the problem of defining reference architecture for autonomous operations of maritime systems. This paper summarizes its efforts to date.

Architecture for autonomy

NASA Astrophysics Data System (ADS)

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, open to public scrutiny and modification, now rival commercial frameworks in both quality and economic impact. Further, industry now realizes that open source frameworks can reduce cost and risk of systems engineering. This paper describes the Architecture for Autonomy implemented by DRDC and how this architecture meets DRDC's current needs. It also presents an argument for why this architecture should also satisfy DRDC's future requirements as well.

The dimensions of responsiveness of a health system: a Taiwanese perspective.

PubMed

Hsu, Chih-Cheng; Chen, Likwang; Hu, Yu-Whuei; Yip, Winnie; Shu, Chen-Chun

2006-03-17

Responsiveness is an indicator used to measure how well a health system performs relative to non-health aspects. This study assessed whether seven dimensions proposed by the World Health Organization (WHO) to measure responsiveness (dignity, autonomy, confidentiality, prompt attention, social support, basic amenities, and choices of providers) are applicable in evaluating the health system of Taiwan. A key informant survey and focus group research were used in this study. The translated WHO proposed questionnaire was sent to 205 nominated key informants by mail, and 132 (64.4%) were returned. We used principal component analysis to extract factors. Linear regression analysis was used to assess the relationship between the total score and the extracted factors. A qualitative content analysis was also carried out in focus group research. Principal component analysis produced five factors (respect, access, confidentiality, basic amenities, and social support) that explained 63.5% of the total variances. These five factors demonstrated acceptable internal consistency and four of them (except social support) were significantly correlated with the total responsiveness score. The focus group interviews revealed health providers' communication ability and medical ethics were also highly appraised by Taiwanese. When the performance of a health system is to be evaluated, elements of responsiveness proposed by WHO may have to be tailored to fit different cultural backgrounds. Four key features illustrate the uniqueness of Taiwanese perspectives: the idea of autonomy may not be conceptualized, prompt attention and choice of providers are on the same track, social support during care is trivially correlated to the total responsiveness score, and accountability of health providers is deemed essential to a health system.

Challenges and Lessons Learned in the Application of Autonomy to Space Operations

NASA Technical Reports Server (NTRS)

Forrest, David J.

2001-01-01

NASA's Space Operations Management Office (SOMO) is working toward a goal of providing an integrated infrastructure of mission and data services for space missions undertaken by NASA enterprises. A significant portion of this effort is focused on reducing the cost of these services. We are interested in the potential of autonomy to reduce operations costs. SOMO services support space missions, but are not part of the mission objectives; therefore the level of acceptable risk is very low. In fact, SOMO could be effective ly prevented from applying autonomy if customers merely perceive it as adding risk to their mission(s). We are interested in this workshop from the standpoint of understanding what can be done to realize the potential cost savings due to autonomy while maintaining acceptable risk and serving the needs of our customers. We would like to present our lessons learned so far in adopting autonomy and automation, which we think will contribute to clarifying the challenges facing the use of such technology. SOMO provides services to a diverse and ambitious set of mission customers. Many of these missions are groundbreaking missions for which communications, data, and other operations requirements sometimes cannot be clearly articulated early in the program. This motivates a need for systems that are robust in the face of unanticipated situations so that customer missions are not unreasonably constrained or impacted by "shortcomings" in SOMO services. One of SOMO's primary goals is to realize a paradigm in which SOMO acts as a service provider to organizations that fly space missions for NASA, other government agencies, and even the commercial sector. These organizations purchase SOMO services "by the pound" as customers. We have to provide systems that are not experiments themselves, but rather stable bases from which to do bold experiments. To this end, SOMO also seeks to work closely with industry to see that robust autonomy technology gets infused into products and services for the space industry and beyond. The potential for application of these technologies spans space-based communications networks (e.g. TDRSS) and ground-based assets including communication and tracking antenna systems, data networks, and control centers. There are several problems that are candidates for the application of autonomy, if it can be made reliable enough, including: antenna control, antenna scheduling, communication link scheduling and operation, navigation, attitude determination, fault detection, isolation, and reconfiguration (for spacecraft or ground assets), and mission-level planning and scheduling. Some attempts have been made to apply autonomy and automation in these areas in the past with varying degrees of success. We will present relevant case histories and the lessons inferred from them. Combining this past experience with anticipated future needs, we can clarify the challenges that must be met in order to realize the benefits of autonomy.

Doctors and managers: poor relationships may be damaging patients—what can be done?

PubMed Central

Edwards, N

2003-01-01

The problem of poor relationships between doctors and managers is a common feature of many healthcare systems. This problem needs to be explicitly addressed and there are a number of positive steps that could be taken. Firstly, there would be value in working to improve the quality of relationships and better mutual understanding of the necessarily different positions of doctors and managers. Finding a common approach to managing resources, accountability, autonomy, and the creation of more systematic ways of working seems to be important. The use of costed clinical pathways may be one approach. Rather than seeing guidelines and accountability systems as a threat to autonomy there is an argument that they are an essential adjunct to it. Redefining autonomy in order to preserve it and to ensure that it encompasses accountability and responsibility will be an important step. A key step is the development of clinical leadership.

Commitment-Insurance: Compensating for the Autonomy Costs of Interdependence in Close Relationships

PubMed Central

Murray, Sandra L.; Holmes, John G.; Aloni, Maya; Pinkus, Rebecca T.; Derrick, Jaye L.; Leder, Sadie

2014-01-01

A model of the commitment-insurance system is proposed to examine how low and high self-esteem people cope with the costs interdependence imposes on autonomous goal pursuits. In this system, autonomy costs automatically activate compensatory cognitive processes that attach greater value to the partner. Greater partner-valuing compels greater responsiveness to the partner’s needs. Two experiments and a daily diary study of newlyweds supported the model. Autonomy costs automatically activate more positive implicit evaluations of the partner. On explicit measures of positive illusions, high self-esteem people continue to compensate for costs. However, cost-primed low self-esteem people correct and override their positive implicit sentiments when they have the opportunity to do so. Such corrections put the marriages of low self-esteem people at risk: Failing to compensate for costs predicted declines in satisfaction over a one year period. PMID:19634974

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.

Space Station module Power Management And Distribution (PMAD) system

Walls, Bryan

1990-01-01

This project consists of several tasks which are unified toward experimentally demonstrating the operation of a highly autonomous, user-supportive power management and distribution system for Space Station Freedom (SSF) habitation/laboratory modules. This goal will be extended to a demonstration of autonomous, cooperative power system operation for the whole SSF power system through a joint effort with NASA's Lewis Research Center, using their Autonomous Power System. Short term goals for the space station module power management and distribution include having an operational breadboard reflecting current plans for SSF, improving performance of the system communications, and improving the organization and mutability of the artificial intelligence (AI) systems. In the middle term, intermediate levels of autonomy will be added, user interfaces will be modified, and enhanced modeling capabilities will be integrated in the system. Long term goals involve conversion of all software into Ada, vigorous verification and validation efforts and, finally, seeing an impact of this research on the operation of SSF. Conversion of the system to a DC Star configuration is now in progress, and should be completed by the end of October, 1989. This configuration reflects the latest SSF module architecture. Hardware is now being procured which will improve system communications significantly. The Knowledge-Based Management System (KBMS) is initially developed and the rules from FRAMES have been implemented in the KBMS. Rules in the other two AI systems are also being grouped modularly, making them more tractable, and easier to eventually move into the KBMS. Adding an intermediate level of autonomy will require development of a planning utility, which will also be built using the KBMS. These changes will require having the user interface for the whole system available from one interface. An Enhanced Model will be developed, which will allow exercise of the system through the interface without requiring all of the power hardware to be operational. The functionality of the AI systems will continue to be advanced, including incipient failure detection. Ada conversion will begin with the lowest level processor (LLP) code. Then selected pieces of the higher level functionality will be recorded in Ada and, where possible, moved to the LLP level. Validation and verification will be done on the Ada code, and will complete sometimes after completion of the Ada conversion.

New Automotive Air Conditioning System Simulation Tool Developed in MATLAB/Simulink

Kiss, T.; Chaney, L.; Meyer, J.

Further improvements in vehicle fuel efficiency require accurate evaluation of the vehicle's transient total power requirement. When operated, the air conditioning (A/C) system is the largest auxiliary load on a vehicle; therefore, accurate evaluation of the load it places on the vehicle's engine and/or energy storage system is especially important. Vehicle simulation software, such as 'Autonomie,' has been used by OEMs to evaluate vehicles' energy performance. A transient A/C simulation tool incorporated into vehicle simulation models would also provide a tool for developing more efficient A/C systems through a thorough consideration of the transient A/C system performance. The dynamic systemmore » simulation software Matlab/Simulink was used to develop new and more efficient vehicle energy system controls. The various modeling methods used for the new simulation tool are described in detail. Comparison with measured data is provided to demonstrate the validity of the model.« less

In order to meet the requirements of autonomy and reliability for the navigation system, combined with the method of measuring speed by using the spectral redshift information of the natural celestial bodies, a new scheme, consisting of Strapdown Inertial Navigation System (SINS)/Spectral Redshift (SRS)/Geomagnetic Navigation System (GNS), is designed for autonomous integrated navigation systems. The principle of this SINS/SRS/GNS autonomous integrated navigation system is explored, and the corresponding mathematical model is established. Furthermore, a robust adaptive central difference particle filtering algorithm is proposed for this autonomous integrated navigation system. The simulation experiments are conducted and the results show that the designed SINS/SRS/GNS autonomous integrated navigation system possesses good autonomy, strong robustness and high reliability, thus providing a new solution for autonomous navigation technology.

The present studies examined whether implicit or explicit autonomy dispositions moderate the relationship between felt autonomy and well-being. Study 1 (N = 187 undergraduate students) presents an initial test of the moderator hypothesis by predicting flow experience from the interaction of autonomy need satisfaction and autonomy dispositions. Study 2 (N = 127 physically inactive persons) used vignettes involving an autonomy (un)supportive coach to test a moderated mediation model in which perceived coach autonomy support leads to well-being through basic need satisfaction. Again, the effects of need satisfaction on well-being were hypothesized to be moderated by an implicit autonomy disposition. Study 1 showed that individuals with a strong implicit autonomy (but not power or achievement) motive disposition derived more flow experience from felt autonomy than individuals with a weak implicit autonomy disposition. Study 2 revealed that perceived autonomy support from sports coaches, which we experimentally induced with a vignette method, leads to autonomy satisfaction, leading in turn to positive effects on well-being. This indirect effect held at high and average but not low implicit autonomy disposition. The results indicate that the degree to which people benefit from autonomy need satisfaction depends on their implicit disposition toward autonomy. © 2014 Wiley Periodicals, Inc.

There is a significant gap between the services offered by existing space qualified Real-Time Operating Systems (RTOS) and those required by the most demanding future space applications. New requirements for autonomy, terrain mapping and navigation, Simultaneous Location and Mapping (SLAM), improvement of the throughput of science tasks, all demand high level services such as file systems or POSIX compliant interfaces. xLuna is an operating system that aims fulfilling these new requirements. Besides providing the typical services that of an RTOS (tasks and interrupts management, timers, message queues, etc), it also includes most of the features available in modern general-purpose operating systems, such as Linux. This paper describes a case study that proposes to demonstrate the usage of xLuna on board a rover currently in use for the development of algorithms in preparation of a mission to Mars.

Privacy, autonomy, and public policy: French and North American perspectives.

Merchant, Jennifer

2016-12-01

This article raises the question of whether in both the United States and in France, an individual's autonomy and private decision-making right(s) in matters of health care and access to reproductive technologies can be conciliated with the general interest, and more specifically, the role of the State. Can a full-fledged right to privacy, the ability to exercise one's autonomy, exist alongside the general interest, and depend neither on financial resources like in the United States nor on centralised government decisions or the medical hierarchy like in France? The contrast between these two modern democracies justify the importance of comparing them. I will demonstrate that overlaps do exist: the free exercise of religion and opinion, freedom of expression, the inherent value of each individual. What differs, however, are the institutions and how they provide, protect, promote, or frame access to and expressions of these democratic principles. The impact of the global economy, the exposure of people around the world to each other via the internet, and the mirror effects of social media, blogs, and other such forums, have created new perspectives that countries project onto one another. For example, does France now seem to tout 'autonomy' as a new and important value because it appears to be an 'American success story'? Does the United States now seem to value human rights and a social-democratic approach because of the 'French model'? There seems to be some truth behind these assertions, but as this article will demonstrate, the portrayals of what the 'right to privacy' is in the United States and what 'socialised medicine' is in France are not necessarily fully accurate.

Unmanned aerial systems, advanced cockpits, and air traffic management are all seeing dramatic increases in automation. However, while automation may take on some tasks previously performed by humans, humans will still be required to remain in the system for the foreseeable future. The collaboration between humans and these increasingly autonomous systems will begin to resemble cooperation between teammates, rather than simple task allocation. It is critical to understand this human-autonomy teaming (HAT) to optimize these systems in the future. One methodology to understand HAT is by identifying recurring patterns of HAT that have similar characteristics and solutions. This paper applies a methodology for identifying HAT patterns to an advanced cockpit project.

Solving Autonomy Technology Gaps through Wireless Technology and Orion Avionics Architectural Principles

NASA Astrophysics Data System (ADS)

Black, Randy; Bai, Haowei; Michalicek, Andrew; Shelton, Blaine; Villela, Mark

2008-01-01

Currently, autonomy in space applications is limited by a variety of technology gaps. Innovative application of wireless technology and avionics architectural principles drawn from the Orion crew exploration vehicle provide solutions for several of these gaps. The Vision for Space Exploration envisions extensive use of autonomous systems. Economic realities preclude continuing the level of operator support currently required of autonomous systems in space. In order to decrease the number of operators, more autonomy must be afforded to automated systems. However, certification authorities have been notoriously reluctant to certify autonomous software in the presence of humans or when costly missions may be jeopardized. The Orion avionics architecture, drawn from advanced commercial aircraft avionics, is based upon several architectural principles including partitioning in software. Robust software partitioning provides "brick wall" separation between software applications executing on a single processor, along with controlled data movement between applications. Taking advantage of these attributes, non-deterministic applications can be placed in one partition and a "Safety" application created in a separate partition. This "Safety" partition can track the position of astronauts or critical equipment and prevent any unsafe command from executing. Only the Safety partition need be certified to a human rated level. As a proof-of-concept demonstration, Honeywell has teamed with the Ultra WideBand (UWB) Working Group at NASA Johnson Space Center to provide tracking of humans, autonomous systems, and critical equipment. Using UWB the NASA team can determine positioning to within less than one inch resolution, allowing a Safety partition to halt operation of autonomous systems in the event that an unplanned collision is imminent. Another challenge facing autonomous systems is the coordination of multiple autonomous agents. Current approaches address the issue as one of networking and coordination of multiple independent units, each with its own mission. As a proof-of-concept Honeywell is developing and testing various algorithms that lead to a deterministic, fault tolerant, reliable wireless backplane. Just as advanced avionics systems control several subsystems, actuators, sensors, displays, etc.; a single "master" autonomous agent (or base station computer) could control multiple autonomous systems. The problem is simplified to controlling a flexible body consisting of several sensors and actuators, rather than one of coordinating multiple independent units. By filling technology gaps associated with space based autonomous system, wireless technology and Orion architectural principles provide the means for decreasing operational costs and simplifying problems associated with collaboration of multiple autonomous systems.

Design and validation of a GNC system for missions to asteroids: the AIM scenario

2017-12-01

Deep space missions, and in particular missions to asteroids, impose a certain level of autonomy that depends on the mission objectives. If the mission requires the spacecraft to perform close approaches to the target body (the extreme case being a landing scenario), the autonomy level must be increased to guarantee the fast and reactive response which is required in both nominal and contingency operations. The GNC system must be designed in accordance with the required level of autonomy. The GNC system designed and tested in the frame of ESA's Asteroid Impact Mission (AIM) system studies (Phase A/B1 and Consolidation Phase) is an example of an autonomous GNC system that meets the challenging objectives of AIM. The paper reports the design of such GNC system and its validation through a DDVV plan that includes Model-in-the-Loop and Hardware-in-the-Loop testing. Main focus is the translational navigation, which is able to provide online the relative state estimation with respect to the target body using exclusively cameras as relative navigation sensors. The relative navigation outputs are meant to be used for nominal spacecraft trajectory corrections as well as to estimate the collision risk with the asteroid and, if needed, to command the execution of a collision avoidance manoeuvre to guarantee spacecraft safety

Situation Awareness of Onboard System Autonomy

We have developed intelligent agent software for onboard system autonomy. Our approach is to provide control agents that automate crew and vehicle systems, and operations assistants that aid humans in working with these autonomous systems. We use the 3 Tier control architecture to develop the control agent software that automates system reconfiguration and routine fault management. We use the Distributed Collaboration and Interaction (DCI) System to develop the operations assistants that provide human services, including situation summarization, event notification, activity management, and support for manual commanding of autonomous system. In this paper we describe how the operations assistants aid situation awareness of the autonomous control agents. We also describe our evaluation of the DCI System to support control engineers during a ground test at Johnson Space Center (JSC) of the Post Processing System (PPS) for regenerative water recovery.

The More, the Better? Curvilinear Effects of Job Autonomy on Well-Being From Vitamin Model and PE-Fit Theory Perspectives.

PubMed

Stiglbauer, Barbara; Kovacs, Carrie

2017-12-28

In organizational psychology research, autonomy is generally seen as a job resource with a monotone positive relationship with desired occupational outcomes such as well-being. However, both Warr's vitamin model and person-environment (PE) fit theory suggest that negative outcomes may result from excesses of some job resources, including autonomy. Thus, the current studies used survey methodology to explore cross-sectional relationships between environmental autonomy, person-environment autonomy (mis)fit, and well-being. We found that autonomy and autonomy (mis)fit explained between 6% and 22% of variance in well-being, depending on type of autonomy (scheduling, method, or decision-making) and type of (mis)fit operationalization (atomistic operationalization through the separate assessment of actual and ideal autonomy levels vs. molecular operationalization through the direct assessment of perceived autonomy (mis)fit). Autonomy (mis)fit (PE-fit perspective) explained more unique variance in well-being than environmental autonomy itself (vitamin model perspective). Detrimental effects of autonomy excess on well-being were most evident for method autonomy and least consistent for decision-making autonomy. We argue that too-much-of-a-good-thing effects of job autonomy on well-being exist, but suggest that these may be dependent upon sample characteristics (range of autonomy levels), type of operationalization (molecular vs. atomistic fit), autonomy facet (method, scheduling, or decision-making), as well as individual and organizational moderators.

To assess the inter-rater reliability and concurrent validity of the Communication Evaluation in Rehabilitation Tool, which aims to externally assess physiotherapists competency in using Self-Determination Theory-based communication strategies in practice. Audio recordings of initial consultations between 24 physiotherapists and 24 patients with chronic low back pain in four hospitals in Ireland were obtained as part of a larger randomised controlled trial. Three raters, all of whom had Ph.Ds in psychology and expertise in motivation and physical activity, independently listened to the 24 audio recordings and completed the 18-item Communication Evaluation in Rehabilitation Tool. Inter-rater reliability between all three raters was assessed using intraclass correlation coefficients. Concurrent validity was assessed using Pearson's r correlations with a reference standard, the Health Care Climate Questionnaire. The total score for the Communication Evaluation in Rehabilitation Tool is an average of all 18 items. Total scores demonstrated good inter-rater reliability (Intraclass Correlation Coefficient (ICC) = 0.8) and concurrent validity with the Health Care Climate Questionnaire total score (range: r = 0.7-0.88). Item-level scores of the Communication Evaluation in Rehabilitation Tool identified five items that need improvement. Results provide preliminary evidence to support future use and testing of the Communication Evaluation in Rehabilitation Tool. Implications for Rehabilitation Promoting patient autonomy is a learned skill and while interventions exist to train clinicians in these skills there are no tools to assess how well clinicians use these skills when interacting with a patient. The lack of robust assessment has severe implications regarding both the fidelity of clinician training packages and resulting outcomes for promoting patient autonomy. This study has developed a novel measurement tool Communication Evaluation in Rehabilitation Tool and a comprehensive user manual to assess how well health care providers use autonomy-supportive communication strategies in real world-clinical settings. This tool has demonstrated good inter-rater reliability and concurrent validity in its initial testing phase. The Communication Evaluation in Rehabilitation Tool can be used in future studies to assess autonomy-supportive communication and undergo further measurement property testing as per our recommendations.

Autonomous orientation predicts longevity: New findings from the Nun Study.

Work on longevity has found protective social, cognitive, and emotional factors, but to date we have little understanding of the impact of motivational dynamics. Autonomy orientation, or stable patterns of self-regulation, is theorized to be a protective factor for long-term mental and physical health (Ryan & Deci, 2017), and it is therefore a prime candidate for examining how stable psychosocial factors are linked to longevity, or life expectancy. Essays written in the 1930s by participants in the Nun Study were coded for indicators of an autonomy orientation. These were selected in line with an extensive theoretical literature based in self-determination theory (Deci & Ryan, 1985). Essays were coded for the propensity for choice in action, susceptibility to pressure, self-reflection, integration of experiences, and parental support for autonomy. These coded variables were used to predict age of death. Using 176 codable essays provided by now-deceased participants, linear regression analyses revealed that choiceful behavior, self-reflection, and parent autonomy support predicted age of death. Participants who demonstrated these stable and beneficial motivational characteristics lived longer. Personality constructs reflecting a healthy form of self-regulation are associated with long-term health. Implications for health interventions are discussed. © 2018 The Authors.

Policy formulation and adoption often happen in a black box. Implementation challenges affect and modify the nature of a policy. We analyzed hospitals' autonomy policy in Iran that was intended to reduce hospitals' financial burden on government and improve their efficiency. We followed a retrospective case-study methodology, involving inductive and deductive analyses of parliamentary proceedings, policy documents, gray literature, published papers and interview transcripts. We analyzed data to develop a policy map that included important dates and events leading to the policy process milestones. We identified four time-periods with distinctive features: 'moving toward the policy' (1989 - 1994), disorganized implementation' (1995 - 1997), 'continuing challenges and indecisiveness in hospitals financing' (1998 - 2003), and 'other structural and financial policies in public hospitals' (2004 to date). We found that stakeholders required different and conflicting objectives, which certainly resulted in an unsatisfactory implementation process. The policy led to long-lasting and often negative changes in the hospital sector and the entire Iranian health system. Hospital autonomy appeared to be an ill-advised policy to remedy the inefficiency problems in low socioeconomic areas of the country. The assumption that hospital autonomy reforms would necessarily result in a better health system, may be a false assumption as their success relies on many contextual, structural and policy implementation factors.

Does autonomization of public hospitals and exposure to market pressure complement or debilitate social health insurance systems? Evidence from a low-income country.

PubMed

Granting public hospitals greater autonomy and creating organizational arrangements that mimic the private sector and encourage competition is often promoted as a way to increase efficiency and public accountability and to improve quality of care at these facilities. The existence of good-quality health infrastructure, in turn, encourages the population to join and support the social health insurance system and achieve universal coverage. This article provides a critical review of hospital autonomization, using Vietnam's experience to assess the influence of hospital autonomy on the sustainability of Vietnam's social health insurance. The evidence suggests that a reform process based on greater autonomy of resource mobilization and on the retention and use of own-source revenues can create perverse incentives among managers and health care providers, leading to the development of a two-tiered provision of clinical care, provider-induced supply of an inefficient service mix, a high degree of duplication, wasteful investment, and cost escalation. Rather than complementing social health insurance and helping the country to achieve universal coverage, granting public hospitals greater autonomy that mimics the private sector may indeed undermine the legitimacy and sustainability of social health insurance as health care costs escalate and higher quality of care remains elusive.

Goals and everyday problem solving: examining the link between age-related goals and problem-solving strategy use.

Qualitative interviews on family and financial problems from 332 adolescents, young, middle-aged, and older adults, demonstrated that developmentally relevant goals predicted problem-solving strategy use over and above problem domain. Four focal goals concerned autonomy, generativity, maintaining good relationships with others, and changing another person. We examined both self- and other-focused problem-solving strategies. Autonomy goals were associated with self-focused instrumental problem solving and generative goals were related to other-focused instrumental problem solving in family and financial problems. Goals of changing another person were related to other-focused instrumental problem solving in the family domain only. The match between goals and strategies, an indicator of problem-solving adaptiveness, showed that young individuals displayed the greatest match between autonomy goals and self-focused problem solving, whereas older adults showed a greater match between generative goals and other-focused problem solving. Findings speak to the importance of considering goals in investigations of age-related differences in everyday problem solving.

Four studies assessed the potentially detrimental effects that restrictions to collective autonomy (i.e., a group's freedom to determine and practice its own identity) may have for the personal autonomy and psychological well-being of group members. In Study 1, using 3 distinct samples (NSample1a = 123, NSample1b = 129, NSample1c = 370), correlational and cross-cultural evidence indicates that perceived restrictions to the collective autonomy of one's group is directly associated with reduced personal autonomy, and indirectly associated with diminished well-being through personal autonomy. In Study 2 (N = 411), a longitudinal assessment of group members over 3 time-points during a 4-month period found that group members who perceived greater collective autonomy restriction also experienced reduced personal autonomy, and in turn, reduced psychological well-being over time. In Study 3 (N = 255), group members described a time during which their ingroup had (or did not have) its collective autonomy unduly restricted by other groups. Participants who were primed to think that their group lacked collective autonomy reported reduced feelings of personal autonomy, and reduced psychological well-being (compared with those primed to think their group had collective autonomy). In Study 4 (N = 389), collective autonomy was manipulated within the context of an intensive laboratory simulation. Collective autonomy-restricted group members experienced less personal autonomy than those who did not have their collective autonomy restricted. Together these findings suggest that restrictions to a group's collective autonomy may have detrimental consequences for the personal autonomy and psychological well-being of group members.

AMO EXPRESS: A Command and Control Experiment for Crew Autonomy Onboard the International Space Station

2015-01-01

NASA is investigating a range of future human spaceflight missions, including both Mars-distance and Near Earth Object (NEO) targets. Of significant importance for these missions is the balance between crew autonomy and vehicle automation. As distance from Earth results in increasing communication delays, future crews need both the capability and authority to independently make decisions. However, small crews cannot take on all functions performed by ground today, and so vehicles must be more automated to reduce the crew workload for such missions. NASA's Advanced Exploration Systems Program funded Autonomous Mission Operations (AMO) project conducted an autonomous command and control experiment on-board the International Space Station that demonstrated single action intelligent procedures for crew command and control. The target problem was to enable crew initialization of a facility class rack with power and thermal interfaces, and involving core and payload command and telemetry processing, without support from ground controllers. This autonomous operations capability is enabling in scenarios such as initialization of a medical facility to respond to a crew medical emergency, and representative of other spacecraft autonomy challenges. The experiment was conducted using the Expedite the Processing of Experiments for Space Station (EXPRESS) rack 7, which was located in the Port 2 location within the U.S Laboratory onboard the International Space Station (ISS). Activation and deactivation of this facility is time consuming and operationally intensive, requiring coordination of three flight control positions, 47 nominal steps, 57 commands, 276 telemetry checks, and coordination of multiple ISS systems (both core and payload). Utilization of Draper Laboratory's Timeliner software, deployed on-board the ISS within the Command and Control (C&C) computers and the Payload computers, allowed development of the automated procedures specific to ISS without having to certify and employ novel software for procedure development and execution. The procedures contained the ground procedure logic and actions as possible to include fault detection and recovery capabilities.

Systems Architecture for Fully Autonomous Space Missions

Esper, Jamie; Schnurr, R.; VanSteenberg, M.; Brumfield, Mark (Technical Monitor)

2002-01-01

The NASA Goddard Space Flight Center is working to develop a revolutionary new system architecture concept in support of fully autonomous missions. As part of GSFC's contribution to the New Millenium Program (NMP) Space Technology 7 Autonomy and on-Board Processing (ST7-A) Concept Definition Study, the system incorporates the latest commercial Internet and software development ideas and extends them into NASA ground and space segment architectures. The unique challenges facing the exploration of remote and inaccessible locales and the need to incorporate corresponding autonomy technologies within reasonable cost necessitate the re-thinking of traditional mission architectures. A measure of the resiliency of this architecture in its application to a broad range of future autonomy missions will depend on its effectiveness in leveraging from commercial tools developed for the personal computer and Internet markets. Specialized test stations and supporting software come to past as spacecraft take advantage of the extensive tools and research investments of billion-dollar commercial ventures. The projected improvements of the Internet and supporting infrastructure go hand-in-hand with market pressures that provide continuity in research. By taking advantage of consumer-oriented methods and processes, space-flight missions will continue to leverage on investments tailored to provide better services at reduced cost. The application of ground and space segment architectures each based on Local Area Networks (LAN), the use of personal computer-based operating systems, and the execution of activities and operations through a Wide Area Network (Internet) enable a revolution in spacecraft mission formulation, implementation, and flight operations. Hardware and software design, development, integration, test, and flight operations are all tied-in closely to a common thread that enables the smooth transitioning between program phases. The application of commercial software development techniques lays the foundation for delivery of product-oriented flight software modules and models. Software can then be readily applied to support the on-board autonomy required for mission self-management. An on-board intelligent system, based on advanced scripting languages, facilitates the mission autonomy required to offload ground system resources, and enables the spacecraft to manage itself safely through an efficient and effective process of reactive planning, science data acquisition, synthesis, and transmission to the ground. Autonomous ground systems in turn coordinate and support schedule contact times with the spacecraft. Specific autonomy software modules on-board include mission and science planners, instrument and subsystem control, and fault tolerance response software, all residing within a distributed computing environment supported through the flight LAN. Autonomy also requires the minimization of human intervention between users on the ground and the spacecraft, and hence calls for the elimination of the traditional operations control center as a funnel for data manipulation. Basic goal-oriented commands are sent directly from the user to the spacecraft through a distributed internet-based payload operations "center". The ensuing architecture calls for the use of spacecraft as point extensions on the Internet. This paper will detail the system architecture implementation chosen to enable cost-effective autonomous missions with applicability to a broad range of conditions. It will define the structure needed for implementation of such missions, including software and hardware infrastructures. The overall architecture is then laid out as a common thread in the mission life cycle from formulation through implementation and flight operations.

Analysis of trust in autonomy for convoy operations

With growing use of automation in civilian and military contexts that engage cooperatively with humans, the operator's level of trust in the automated system is a major factor in determining the efficacy of the human-autonomy teams. Suboptimal levels of human trust in autonomy (TiA) can be detrimental to joint team performance. This mis-calibrated trust can manifest in several ways, such as distrust and complete disuse of the autonomy or complacency, which results in an unsupervised autonomous system. This work investigates human behaviors that may reflect TiA in the context of an automated driving task, with the goal of improving team performance. Subjects performed a simulated leaderfollower driving task with an automated driving assistant. The subjects had could choose to engage an automated lane keeping and active cruise control system of varying performance levels. Analysis of the experimental data was performed to identify contextual features of the simulation environment that correlated to instances of automation engagement and disengagement. Furthermore, behaviors that potentially indicate inappropriate TiA levels were identified in the subject trials using estimates of momentary risk and agent performance, as functions of these contextual features. Inter-subject and intra-subject trends in automation usage and performance were also identified. This analysis indicated that for poorer performing automation, TiA decreases with time, while higher performing automation induces less drift toward diminishing usage, and in some cases increases in TiA. Subject use of automation was also found to be largely influenced by course features.

The present study is a follow-up of a research project made in 1978 by the Equipe de Recherche Opérationnelle en Santé (EROS) of the Department of Health Administration at the Université de Montréal. The aims were a) firstly to construct a classification instrument by type for long-term care patients, enabling us, to identify these beneficiaries' needs, as well as to guide their placement in a health services' system. And b) to evaluate this instrument (realibility and validity), c) to initiate its implementation and d) to utilize it for evaluating the present placement system. This study constitutes the first stage in an approach aimed at producing, on the basis of a systematic scanning of data collected within the framework of the above-mentioned project; a comprehensive descriptive analysis of the social/health characteristics of an aged population (65 years and over) in one of Quebec's social/ health regions i.e. Montreal's South Shore. At first, the authors define the context and the objectives of the study undertaken; secondly, they define the concept of autonomy by showing how the latter is expressed concretely according to the observation instrument (evaluation form of the individual's functional autonomy). Thirdly, a presentation is made of the method of measurement, as well as certain results concerning an index of restricted autonomy directly released to situations of observable behaviour (e, g. daily-life activities, exploring the outside world, and housekeeping).

International testing of a Mars rover prototype

Tests on a prototype engineering model of the Russian Mars 96 Rover were conducted by an international team in and near Death Valley in the United States in late May, 1992. These tests were part of a comprehensive design and testing program initiated by the three Russian groups responsible for the rover development. The specific objectives of the May tests were: (1) evaluate rover performance over different Mars-like terrains; (2) evaluate state-of-the-art teleoperation and autonomy development for Mars rover command, control and navigation; and (3) organize an international team to contribute expertise and capability on the rover development for the flight project. The range and performance that can be planned for the Mars mission is dependent on the degree of autonomy that will be possible to implement on the mission. Current plans are for limited autonomy, with Earth-based teleoperation for the nominal navigation system. Several types of television systems are being investigated for inclusion in the navigation system including panoramic camera, stereo, and framing cameras. The tests used each of these in teleoperation experiments. Experiments were included to consider use of such TV data in autonomy algorithms. Image processing and some aspects of closed-loop control software were also tested. A micro-rover was tested to help consider the value of such a device as a payload supplement to the main rover. The concept is for the micro-rover to serve like a mobile hand, with its own sensors including a television camera.

Sensor Data Qualification for Autonomous Operation of Space Systems

NASA's new Exploration initiative for both robotic and manned missions will require higher levels of reliability, autonomy and reconfiguration capability to make the missions safe, successful and affordable. Future systems will require diagnostic reasoning to assess the health of the system in order to maintain the system s functionality. The diagnostic reasoning and assessment will involve data qualification, fault detection, fault isolation and remediation control. A team of researchers at the NASA Glenn Research Center is currently working on a Sensor Data Qualification (SDQ) system that will support these critical evaluation processes, for both automated and human-in-the-loop applications. Data qualification is required as a first step so that critical safety and operational decisions are based on good data. The SDQ system would monitor a network of related sensors to determine the health of individual sensors within that network. Various diagnostic systems such as the Caution and Warning System would then use the sensor health information with confidence. The proposed SDQ technology will be demonstrated on a variety of subsystems that are relevant to NASA s Exploration systems, which currently include an electrical power system and a cryogenic fluid management system. The focus of this paper is the development and demonstration of a SDQ application for a prototype power distribution unit that is representative of a Crew Exploration Vehicle electrical power system; this provides a unique and relevant environment in which to demonstrate the feasibility of the SDQ technology.

Recent studies report that the majority of older adults wish to live in their own homes, for as long as possible. This creates a growing interest in technologies to enable older people to remain living independently at home. The purpose of this article is to provide a narrative review of current technology appropriate for older adults' home use. The key research questions were as follow: 1- What is the evidence demonstrating that gerontechnologies are effective in enabling independent living? 2- What are devices designed specifically for frail elderly persons ? Several publications were identified about devices targeting social isolation (videophonic communication, affective orthotic devices or companion-type robots, personal emergency response systems [security]), autonomy loss (technologies for maintenance of autonomy in the activities of daily living) and cognitive disorders (cognitive orthotics, wandering management systems, telemonitoring). Very few articles dealt specifically with the frail older person. In particular, there was extremely limited evidence on use and efficacy of these devices within this population. There is a need to obtain a consensus on definition of the technologies, and also to revisit work strategies and develop innovative business models. To meet this goal, we need to create a network of technological companies, aging services organizations, end-users, academics, and government representatives to explore the real needs of the frail older population and to develop and validate new devices promoting aging at home.

The public health implications of world trade negotiations on the general agreement on trade in services and public services.

Trade ministries from the World Trade Organization's (WTO's) 144 member states are presently deciding which public services to open to foreign competition under the complex liberalisation rules of the general agreement on trade in services (GATS). A frequent criticism of the WTO system is that it reduces national autonomy over public policy. However, respect for national sovereignty is asserted in the GATS treaty. Here, we examine claims made by the WTO and others that GATS exempts public services and does not require their privatisation. We discuss trade treaty processes that can subject public services to commercial rules, the treaty's flexibility with respect to national autonomy, and the effect of GATS in situations in which national autonomy is not protected. We conclude that national autonomy over health policy is not preserved under GATS, and that accordingly, there is a role for international standards that protect public services from the adverse effect of trade and market forces.

Decentralization strategies and provider incentives in healthcare: evidence from the english national health service.

Mannion, Russell; Goddard, Maria; Kuhn, Michael; Bate, Angela

2005-01-01

This article examines the incentive effects of delegating operational and financial decision making from central government to local healthcare providers. It addresses the economic consequences of a contemporary policy initiative in the English National Health Service (NHS)-earned autonomy. This policy entails awarding operational autonomy to 'front-line' organisations that are assessed to be meeting national performance targets. In doing so, it introduces new types of incentives into the healthcare system, changes the nature of established agency relationships and represents a novel approach to performance management. Theoretical elements of a principal-agent model are used to examine the impact of decentralization in the context of the results of an empirical study that elicited the perceptions of senior hospital managers regarding the incentive effects of earned autonomy. A multi-method approach was adopted. In order to capture the breadth of policy impact, we conducted a national postal questionnaire survey of all Chief Executives in acute-care hospital Trusts in England (n = 173). To provide added depth and richness to our understanding of the impact and incentive effects of earned autonomy at an organisational level, we interviewed senior managers in a purposeful sample of eight acute-care hospital Trusts. This theoretical framework and our empirical work suggest that some aspects of the earned autonomy as currently implemented in the NHS serve to weaken the potential incentive effect of decentralization. In particular, the nature of the freedoms is such that many senior managers do not view autonomy as a particularly valuable prize. This suggests that incentives associated with the policy will be insufficiently powerful to motivate providers to deliver better performance. We also found that principal commitment may be a problem in the NHS. Some hospital managers reported that they already enjoyed a large degree of autonomy, regardless of their current performance ratings. We also found evidence that the objectives of providers may differ from those of both the central government and local purchasers. There is, therefore, a risk that granting greater autonomy will allow providers to pursue their own objectives which, whilst not self-serving, may still jeopardize the achievement of strategic goals. It is apparent that the design and implementation features of decentralizing policies such as earned autonomy require careful attention if an optimal balance is to be struck between central oversight and local autonomy in the delivery of healthcare.

Duty of care and autonomy: how support workers managed the tension between protecting service users from risk and promoting their independence in a specialist group home.

PubMed

2011-09-01

In the UK those paid to support adults with intellectual disabilities must manage two potentially conflicting duties that are set out in policy documents as being vital to their role: protecting service users (their duty of care) and recognising service users' autonomy. This study focuses specifically on the support of people with the genetically determined condition, Prader-Willi syndrome (PWS). Due to the behaviours associated with PWS, the support of this group of people vividly illustrates the tension between respect for autonomy and duty of care. This article explores how support workers working in a residential group home managed their competing duties of managing risk and promoting independence in practice. An ethnographic study, comprising of qualitative observations, semi-structured interviews and documentary analysis, was undertaken to investigate the work of support workers in a UK residential group home specialising in the support of adults diagnosed with PWS. The study focused on how support workers attempted to reconcile the tension between protecting service users from the risks associated with the syndrome and acknowledging service users' autonomy by enabling independence. Findings demonstrate that risk was central to the structure of care delivery at the group home and support workers often adhered to standardised risk management procedures. The organisation also required support workers to promote service users' independence and many thought acknowledging service users' autonomy through the promotion of their independence was important. To manage tensions between their differing duties, some support workers deviated from standardised risk management procedures to allow service users a degree of independence. There is a tension between the duty of care and the duty to recognise autonomy at the level of service delivery in residential homes. Support workers attempt to manage this tension; however, further work needs to be done by both residential services and policy makers to facilitate the reconciliation of the duty of care with the duty to recognise service users' autonomy in practice. © 2011 The Authors.

Wang, Lijuan

2017-05-01

This study applies the self-determination theory (SDT) to test the hypothesized relationships among perceived autonomy support from parents, physical education (PE) teachers, and peers, the fulfilment of psychological needs (i.e., autonomy, competence, and relatedness), autonomous motivation, and leisure-time physical activity of Chinese adolescents. There are 255 grade six to eight student participants from four middle schools around Shanghai, China included in this study. An accelerometer was used to measure the moderate-to-vigorous physical activity (MVPA). The participants completed the questionnaires regarding SDT variables. The structural equation modelling was applied to examine the hypothesized relationships among the study variables. The model of hypothesized relationships demonstrated a good fit with the data [X 2  = 20.84, df = 9, P = .01; CFI = 0.98; IFI = 0.98; SRMR = 0.04; RMSEA = 0.05]. The findings revealed that autonomy support from parents, PE teachers, and peers foster social conditions in which the three basic psychological needs can be met. In turn, autonomy, competence, and relatedness are positively associated with autonomous motivation for MVPA. The autonomous motivation positively relates to the MVPA time of adolescents. The three psychological needs partially mediate the influence of autonomy support from parents (β = 0.18, P < .01; Bootstrap 95% CI = 0.06-0.33) and teachers (β = 0.17, P < .01; Bootstrap 95% CI = 0.03-0.26) in the autonomous motivation. In conclusion, these findings support the applicability of SDT in understanding and promoting physical activity of Chinese adolescents.

Biologically-Inspired Concepts for Autonomic Self-Protection in Multiagent Systems

2006-01-01

Biologically-inspired autonomous and autonomic systems (AAS) are essentially concerned with creating self-directed and self-managing systems based on metaphors &om nature and the human body, such as the autonomic nervous system. Agent technologies have been identified as a key enabler for engineering autonomy and autonomicity in systems, both in terms of retrofitting into legacy systems and in designing new systems. Handing over responsibility to systems themselves raises concerns for humans with regard to safety and security. This paper reports on the continued investigation into a strand of research on how to engineer self-protection mechanisms into systems to assist in encouraging confidence regarding security when utilizing autonomy and autonomicity. This includes utilizing the apoptosis and quiescence metaphors to potentially provide a self-destruct or self-sleep signal between autonomic agents when needed, and an ALice signal to facilitate self-identification and self-certification between anonymous autonomous agents and systems.

Unmanned aerial systems, robotics, advanced cockpits, and air traffic management are all examples of domains that are seeing dramatic increases in automation. While automation may take on some tasks previously performed by humans, humans will still be required, for the foreseeable future, to remain in the system. The collaboration with humans and these increasingly autonomous systems will begin to resemble cooperation between teammates, rather than simple task allocation. It is critical to understand this human-autonomy teaming (HAT) to optimize these systems in the future. One methodology to understand HAT is by identifying recurring patterns of HAT that have similar characteristics and solutions. This paper applies a methodology for identifying HAT patterns to an advanced cockpit project.

Microbial fuel cells for robotics: energy autonomy through artificial symbiosis.

Ieropoulos, Ioannis A; Greenman, John; Melhuish, Chris; Horsfield, Ian

2012-06-01

The development of the microbial fuel cell (MFC) technology has seen an enormous growth over the last hundred years since its inception by Potter in 1911. The technology has reached a level of maturity that it is now considered to be a field in its own right with a growing scientific community. The highest level of activity has been recorded over the last decade and it is perhaps considered commonplace that MFCs are primarily suitable for stationary, passive wastewater treatment applications. Sceptics have certainly not considered MFCs as serious contenders in the race for developing renewable energy technologies. Yet this is the only type of alternative system that can convert organic waste-widely distributed around the globe-directly into electricity, and therefore, the only technology that will allow artificial agents to autonomously operate in a plethora of environments. This Minireview describes the history and current state-of-the-art regarding MFCs in robotics and their vital role in artificial symbiosis and autonomy. Furthermore, the article demonstrates how pursuing practical robotic applications can provide insights of the core MFC technology in general. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.

The impact of changes in incentives and governance on the motivation of dental practitioners.

PubMed

Harris, Rebecca V; Dancer, Joanna M; Montasem, Alexander

2011-01-01

Recent changes to the system of remuneration and contracting arrangements with Primary Care Trusts (PCTs) has meant that dental practitioners in the UK have experienced several types of incentive and governance arrangements. This paper uses data from a qualitative study of 20 dental practitioners to examine the influence of different systems of incentives and governance on their motivational system. Results show that a perceived reduction in autonomy was the least acceptable aspect of the health reforms. The study also suggests that conflict between self-interested and altruistic motives may occur where medical professionals operate as independent contractors in a small business environment. Whilst dentists appeared to show altruistic motives towards their patients, priorities towards running an autonomous business enterprise meant that PCT managerial requirements, for example, to widen access were not welcomed, because of their impact on managerial autonomy. Moreover, whilst dentists' professional ethos appeared geared towards achieving technically high quality standards of work, this produced tensions against a background of cost containment in a fee-per-item system of remuneration. The paper raises issues such as the person-system interaction associated with professional and individual autonomy and the importance of reciprocity and fair payment.

Manyara, Anthony M.; Molyneux, Sassy; Tsofa, Benjamin

2017-01-01

Background In 2013, Kenya transitioned into a devolved system of government with a central government and 47 semi-autonomous county governments. In this paper, we report early experiences of devolution in the Kenyan health sector, with a focus on public county hospitals. Specifically, we examine changes in hospital autonomy as a result of devolution, and how these have affected hospital functioning. Methods We used a qualitative case study approach to examine the level of autonomy that hospitals had over key management functions and how this had affected hospital functioning in three county hospitals in coastal Kenya. We collected data by in-depth interviews of county health managers and hospital managers in the case study hospitals (n = 21). We adopted the framework proposed by Chawla et al (1995) to examine the autonomy that hospitals had over five management domains (strategic management, finance, procurement, human resource, and administration), and how these influenced hospital functioning. Findings Devolution had resulted in a substantial reduction in the autonomy of county hospitals over the five key functions examined. This resulted in weakened hospital management and leadership, reduced community participation in hospital affairs, compromised quality of services, reduced motivation among hospital staff, non-alignment of county and hospital priorities, staff insubordination, and compromised quality of care. Conclusion Increasing the autonomy of county hospitals in Kenya will improve their functioning. County governments should develop legislation that give hospitals greater control over resources and key management functions. PMID:28771558

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.

Increasing Mission Science Return Through Use of Spacecraft Autonomy and Sensor Webs: A Volcanology Example

NASA Astrophysics Data System (ADS)

Mission science return is increased through use of onboard autonomy, and using disparate assets integrated into an autonomously-operating sensor web that can re-task these assets to rapidly obtain additional data. Software on spacecraft has been used to analyse data to detect dynamic events of high interest, such as on- going volcanic activity. This capability has been successfully demonstrated by the NASA New Millennium Program Autonomous Sciencecraft Experiment (ASE), on the Earth Observing 1 spacecraft in Earth-orbit [1-2]. The potential now exists for eruption parameters to be quantified onboard a spacecraft, using models that relate thermal emission to volumetric eruption rate. This promises a notification not only of on-going activity, but also the magnitude of the event, within a few hours of the original observation, a process that normally takes weeks. ASE/EO-1 is part of the JPL Volcano Sensor Web [3]. This autonomous system collates information of volcanic activity from numerous assets and retasks EO-1 to obtain observations as soon as practicable. The use of a ground-based planner allows rapid insertion or replacement of new observations, with no human intervention. Endusers are notified automatically by email. Spacecraft autonomy, involving automatic fault detection and mitigation, onboard processing of data, and replanning of observations, allows mission operations to break free from pre-ordained operations sequencing, necessary for studying dynamic volcanic processes on other bodies in the Solar System (e.g., Io and Enceladus). Onboard processing allows quantification of dynamic processes, improving both science content per returned byte and optimization of subsequent resource use.

There is an increasing demand for invasive forms of cosmetic surgery. In view of the omnipresent confrontation with some idealized standards of beauty in advertising, films, beauty-shows etc., this paper deals with the question of whether women undergo cosmetic surgery because they are forced by a norm-setting beauty system or whether they choose these operations themselves. I offer an analysis of what could be an adequate concept of autonomous choice in this area. Particularly, it will be shown that a libertarian concept of autonomy is inadequate for analyzing the moral status of cosmetic surgery. A concept of autonomy is outlined that enables us to qualify certain kinds of pressure as autonomy restricting.

A Summary of the NASA Design Environment for Novel Vertical Lift Vehicles (DELIVER) Project

2018-01-01

The number of new markets and use cases being developed for vertical take-off and landing vehicles continues to explode, including the highly publicized urban air taxi and package deliver applications. There is an equally exploding variety of novel vehicle configurations and sizes that are being proposed to fill these new market applications. The challenge for vehicle designers is that there is currently no easy and consistent way to go from a compelling mission or use case to a vehicle that is best configured and sized for the particular mission. This is because the availability of accurate and validated conceptual design tools for these novel types and sizes of vehicles have not kept pace with the new markets and vehicles themselves. The Design Environment for Novel Vertical Lift Vehicles (DELIVER) project was formulated to address this vehicle design challenge by demonstrating the use of current conceptual design tools, that have been used for decades to design and size conventional rotorcraft, applied to these novel vehicle types, configurations and sizes. In addition to demonstrating the applicability of current design and sizing tools to novel vehicle configurations and sizes, DELIVER also demonstrated the addition of key transformational technologies of noise, autonomy, and hybrid-electric and all-electric propulsion into the vehicle conceptual design process. Noise is key for community acceptance, autonomy and the need to operate autonomously are key for efficient, reliable and safe operations, and electrification of the propulsion system is a key enabler for these new vehicle types and sizes. This paper provides a summary of the DELIVER project and shows the applicability of current conceptual design and sizing tools novel vehicle configurations and sizes that are being proposed for urban air taxi and package delivery type applications.

2006-01-01

We present an multi-agent model-based autonomy architecture with monitoring, planning, diagnosis, and execution elements. We discuss an internal spacecraft free-flying robot prototype controlled by an implementation of this architecture and a ground test facility used for development. In addition, we discuss a simplified environment control life support system for the spacecraft domain also controlled by an implementation of this architecture. We discuss adjustable autonomy and how it applies to this architecture. We describe an interface that provides the user situation awareness of both autonomous systems and enables the user to dynamically edit the plans prior to and during execution as well as control these agents at various levels of autonomy. This interface also permits the agents to query the user or request the user to perform tasks to help achieve the commanded goals. We conclude by describing a scenario where these two agents and a human interact to cooperatively detect, diagnose and recover from a simulated spacecraft fault.

NASA Goddard has been investing in technology demonstrations of a beacon service, now called Next Generation Broadcast Services (NGBS). NGBS is a global, space-based, communications and navigation service for users of Global Navigation Satellite Systems (GNSS) and the Tracking and Data Relay Satellite System (TDRSS). NGBS will provide an S-band beacon messaging source and radio navigation available to users at orbital altitudes 1400 km and below, increasing the autonomy and resiliency of onboard communication and navigation. NGBS will deliver both one-way radiometric (Doppler and pseudorange) and fast forward data transport services to users. Portions of the overall forward data volume will be allocated for fixed message types while the remaining data volume will be left for user forward command data. The NGBS signal will reside within the 2106.43 MHz spectrum currently allocated for the Space Networks multiple access forward (MAF) service and a live service demonstration is currently being planned via the 2nd and 3rd generation TDRS satellites.

2016-09-01

Using the quasi-experimental design, this study examined the effect of autonomy support on self-determined motivation in elementary school physical education (PE) students. One hundred and twenty six participants were assigned to either the autonomy support group (n = 61) or the control group (n = 65) for a six-week intervention period. Perceived teacher autonomy, perceived autonomy in PE, and self-determined motivation in PE were pre- and post-tested using validated questionnaires. Significant increases in perceived teacher autonomy and perceived autonomy in PE were observed in the autonomy support group, but not in the control group. Intrinsic motivation was higher in the autonomy support group than that in the control group. From an experimental perspective, these findings suggest that the autonomy support was successfully manipulated in the PE classes, which in turn increased the students' perceived autonomy and intrinsic motivation.

Nurse Practitioner Autonomy and Relationships with Leadership Affect Teamwork in Primary Care Practices: a Cross-Sectional Survey.

The Nurse Practitioner (NP) workforce represents a substantial supply of primary care providers able to contribute to meeting a growing demand for care. However, controversy exists regarding the expanding role of NPs in primary care in terms of challenging the teamwork between NPs and physicians. To date, no empirical evidence exists regarding how to promote teamwork in primary care between NPs and physicians. We investigated whether NP autonomy within primary care practices and the relationships they have with leadership affect teamwork between NPs and physicians. Using a cross-sectional survey design, data was collected from 163 primary care practices in Massachusetts. Three hundred and fourteen primary care NPs completed and returned the mail survey yielding a response rate of 40 %. The Autonomy and Independent Practice (AIP) and NP-Administration Relations (NP-AR) scales were used to measure NP independent practice and the relationships with leadership, respectively. These measures were aggregated to the practice level. Teamwork between NPs and physicians was measured at the individual NP level using the Teamwork (TW) scale. The multilevel linear regression models investigated the influence of practice-level NP autonomy and the relationship between NPs and leadership on teamwork. With every unit increase on the practice-level mean score of AIP centered at the grand mean, the mean TW score increased by 0.271 units (p < 0.0001). With every unit increase of NP-AR centered at the grand mean, the mean TW score increased by 0.375 (p < 0.001). Over one-third (41.3 %) of the variance in teamwork could be explained by the final model. The study findings demonstrate that NP autonomy and favorable relationships with leadership improve teamwork. Policy and organizational change should focus on promoting NP autonomy and improving the relationship between NPs and leadership to improve teamwork and consequently improve patient care and outcomes.

2001-01-01

The Adjustable Autonomy Testbed (AAT) is a simulation-based testbed located in the Intelligent Systems Laboratory in the Automation, Robotics and Simulation Division at NASA Johnson Space Center. The purpose of the testbed is to support evaluation and validation of prototypes of adjustable autonomous agent software for control and fault management for complex systems. The AA T project has developed prototype adjustable autonomous agent software and human interfaces for cooperative fault management. This software builds on current autonomous agent technology by altering the architecture, components and interfaces for effective teamwork between autonomous systems and human experts. Autonomous agents include a planner, flexible executive, low level control and deductive model-based fault isolation. Adjustable autonomy is intended to increase the flexibility and effectiveness of fault management with an autonomous system. The test domain for this work is control of advanced life support systems for habitats for planetary exploration. The CONFIG hybrid discrete event simulation environment provides flexible and dynamically reconfigurable models of the behavior of components and fluids in the life support systems. Both discrete event and continuous (discrete time) simulation are supported, and flows and pressures are computed globally. This provides fast dynamic simulations of interacting hardware systems in closed loops that can be reconfigured during operations scenarios, producing complex cascading effects of operations and failures. Current object-oriented model libraries support modeling of fluid systems, and models have been developed of physico-chemical and biological subsystems for processing advanced life support gases. In FY01, water recovery system models will be developed.

The Evolution of Autonomy.

Stammers, Trevor

2015-01-01

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.

Early and middle adolescents' autonomy development: impact of maternal HIV/AIDS.

Progression toward autonomy is considered of central importance during the adolescent period. For young adolescents with an HIV-infected parent, there may be additional challenges. This study investigated current autonomy among early and middle adolescents affected by maternal HIV (N = 108), as well as examined longitudinally the children's responsibility taking when they were younger (age 6-11; N = 81) in response to their mother's illness and their current autonomy as early/middle adolescents. In analyses of self-care and family autonomy, children with greater attachment to their mothers had higher autonomy, and there was a trend for children who drink or use drugs alone to have lower autonomy. In analyses of management autonomy, attachment to peers was associated with higher autonomy. Trajectory group findings indicate that those children who had taken on more responsibility for instrumental caretaking roles directly because of their mother's illness showed better autonomy development as early and middle age adolescents. Therefore, 'parentification' of young children with a mother with HIV may not negatively affect later autonomy development.

The aim of this paper is to propose a new vision on robots. Generally seen as a threat against humanity or at least against employment, we will demonstrate that this new kind of machine can be a support not only for people in loss of autonomy but even for everyone. They will not replace people, they will assist them. The mass production of these companion robots will create a new industry that could take the relay of the automotive and the computer industries in this century. This access to the mass market will require solving technological and acceptability problems by a common work of researchers, engineers, users and the major stakeholders of our society.

The Mission Simulation Toolkit (MST) is a flexible software system for autonomy research. It was developed as part of the Mission Simulation Facility (MSF) project that was started in 2001 to facilitate the development of autonomous planetary robotic missions. Autonomy is a key enabling factor for robotic exploration. There has been a large gap between autonomy software (at the research level), and software that is ready for insertion into near-term space missions. The MST bridges this gap by providing a simulation framework and a suite of tools for supporting research and maturation of autonomy. MST uses a distributed framework based on the High Level Architecture (HLA) standard. A key feature of the MST framework is the ability to plug in new models to replace existing ones with the same services. This enables significant simulation flexibility, particularly the mixing and control of fidelity level. In addition, the MST provides automatic code generation from robot interfaces defined with the Unified Modeling Language (UML), methods for maintaining synchronization across distributed simulation systems, XML-based robot description, and an environment server. Finally, the MSF supports a number of third-party products including dynamic models and terrain databases. Although the communication objects and some of the simulation components that are provided with this toolkit are specifically designed for terrestrial surface rovers, the MST can be applied to any other domain, such as aerial, aquatic, or space.

Using the quasi-experimental design, this study examined the effect of autonomy support on self-determined motivation in elementary school physical education (PE) students. One hundred and twenty six participants were assigned to either the autonomy support group (n = 61) or the control group (n = 65) for a six-week intervention period. Perceived teacher autonomy, perceived autonomy in PE, and self-determined motivation in PE were pre- and post-tested using validated questionnaires. Significant increases in perceived teacher autonomy and perceived autonomy in PE were observed in the autonomy support group, but not in the control group. Intrinsic motivation was higher in the autonomy support group than that in the control group. From an experimental perspective, these findings suggest that the autonomy support was successfully manipulated in the PE classes, which in turn increased the students’ perceived autonomy and intrinsic motivation. Key points The SDT is a relevant theoretical framework for elementary school physical education. Using the quasi-experimental research design, this study is one of the earlies studies supporting that elementary school PE teachers can manipulate the instructional context using the SDT to increase students’ perceived autonomy and intrinsic motivation. Increasing students’ perceived autonomy may not lead to significant changes in other SDT constructs (i.e., amotivation, external regulation, introjected regulation, and identified regulation).

As more assets are placed in orbit, opportunities emerge to combine various sets of satellites in temporary constellations to perform collaborative image collections. Often, new operations concepts for a satellite or set of satellites emerge after launch. To the degree with which new space assets can be inexpensively and rapidly integrated into temporary or "ad hoc" constellations, will determine whether these new ideas will be implemented or not. On the Earth Observing 1 (EO-1) satellite, a New Millennium Program mission, a number of experiments were conducted and are being conducted to demonstrate various aspects of an architecture that, when taken as a whole, will enable progressive mission autonomy. In particular, the target architecture will use adaptive ground antenna arrays to form, as close as possible, the equivalent of wireless access points for low earth orbiting satellites. Coupled with various ground and flight software and the Internet. the architecture enables progressive mission autonomy. Thus, new collaborative sensing techniques can be implemented post-launch. This paper will outline the overall operations concept and highlight details of both the research effort being conducted in

Abstracting event-based control models for high autonomy systems

1993-01-01

A high autonomy system needs many models on which to base control, management, design, and other interventions. These models differ in level of abstraction and in formalism. Concepts and tools are needed to organize the models into a coherent whole. The paper deals with the abstraction processes for systematic derivation of related models for use in event-based control. The multifaceted modeling methodology is briefly reviewed. The morphism concepts needed for application to model abstraction are described. A theory for supporting the construction of DEVS models needed for event-based control is then presented. An implemented morphism on the basis of this theory is also described.

Concepts of “person” and “liberty,” and their implications to our fading notions of autonomy

PubMed Central

Takala, Tuija

2007-01-01

It is commonly held that respect for autonomy is one of the most important principles in medical ethics. However, there are a number of interpretations as to what that respect actually entails in practice and a number of constraints have been suggested even on our self‐regarding choices. These limits are often justified in the name of autonomy. In this paper, it is argued that these different interpretations can be explained and understood by looking at the discussion from the viewpoints of positive and negative liberty and the various notions of a “person” that lay beneath. It will be shown how all the appeals to positive liberty presuppose a particular value system and are therefore problematic in multicultural societies. PMID:17400622

Limited rights of minors in the Dutch healthcare.

In many countries, if not all, the autonomy of minors is limited. Especially in countries with comprehensive legislation in the field of health law the (lack of) autonomy of minors may create challenges. These problems become more complex if the costs of treatment are not paid by the government or covered by insurance. Some challenges are: At what age is a minor able to decide about his health? As not every treatment is the same, how should the system take this into account? The Netherlands has a long history of very comprehensive health care legislation. This legislation includes a section about the treatment of minors that addresses the questions of the conditions in which the autonomy of minors is limited. Though this legislation is limited to the Netherlands other countries face the same challenges.

Space power subsystem automation technology

Graves, J. R. (Compiler)

1982-01-01

The technology issues involved in power subsystem automation and the reasonable objectives to be sought in such a program were discussed. The complexities, uncertainties, and alternatives of power subsystem automation, along with the advantages from both an economic and a technological perspective were considered. Whereas most spacecraft power subsystems now use certain automated functions, the idea of complete autonomy for long periods of time is almost inconceivable. Thus, it seems prudent that the technology program for power subsystem automation be based upon a growth scenario which should provide a structured framework of deliberate steps to enable the evolution of space power subsystems from the current practice of limited autonomy to a greater use of automation with each step being justified on a cost/benefit basis. Each accomplishment should move toward the objectives of decreased requirement for ground control, increased system reliability through onboard management, and ultimately lower energy cost through longer life systems that require fewer resources to operate and maintain. This approach seems well-suited to the evolution of more sophisticated algorithms and eventually perhaps even the use of some sort of artificial intelligence. Multi-hundred kilowatt systems of the future will probably require an advanced level of autonomy if they are to be affordable and manageable.

The effects of autonomy support on salivary alpha-amylase: The role of individual differences.

PubMed

Sieber, Vanda; Schüler, Julia; Wegner, Mirko

2016-12-01

The empirical evidence for the relationship between autonomy-supportive environments and physiological stress is inconsistent. Whereas some studies report a decrease in stress in autonomy-supportive environments, other studies show a negative effect of autonomy on physiological stress. As previous research has not considered individual differences within this relationship, the present research aims to close this empirical gap by proposing that an implicit autonomy disposition, which is defined as a dispositional preference for self-determination, serves as a moderator. In an experiment, we tested whether the autonomy disposition moderates the effect of different teaching styles (controlling, autonomy-supportive, and neutral) on the acute physiological stress response (salivary alpha-amylase) in adolescents (N=69). The study revealed that participants with a high implicit autonomy disposition displayed lower salivary alpha-amylase responses when exposed to autonomy-supportive vignettes compared to when they were exposed to controlling or neutral teaching styles. The opposite pattern was found in students with a low implicit autonomy disposition. The results illustrate that experimentally induced variations in autonomy support lead to different physiological stress responses, depending on individual differences in the implicit autonomy disposition.

The National Space Strategy approved by the President and Congress in 1984 sets for NASA a major goal of conducting effective and productive space applications and technology programs which contribute materially toward United States leadership and security. To contribute to this goal, OAST supports the Nation's civil and defense space programs and overall economic growth. OAST objectives are to ensure timely provision of new concepts and advanced technologies, to support both the development of NASA missions in space and the space activities of industry and other organizations, to utilize the strengths of universities in conducting the NASA space research and technology program, and to maintain the NASA centers in positions of strength in critical space technology areas. In line with these objectives, NASA has established a new program in space automation and robotics that will result in the development and transfer and automation technology to increase the capabilities, productivity, and safety of NASA space programs including the Space Station, automated space platforms, lunar bases, Mars missions, and other deep space ventures. The NASA/OAST Automation and Robotics program is divided into two parts. Ames Research Center has the lead role in developing and demonstrating System Autonomy capabilities for space systems that need to make their own decisions and do their own planning. The Jet Propulsion Laboratory has the lead role for Telerobotics (that portion of the program that has a strong human operator component in the control loop and some remote handling requirement in space). This program is intended to be a working document for NASA Headquarters, Program Offices, and implementing Project Management.

System Engineering of Autonomous Space Vehicles

Human exploration of the solar system requires fully autonomous systems when travelling more than 5 light minutes from Earth. This autonomy is necessary to manage a large, complex spacecraft with limited crew members and skills available. The communication latency requires the vehicle to deal with events with only limited crew interaction in most cases. The engineering of these systems requires an extensive knowledge of the spacecraft systems, information theory, and autonomous algorithm characteristics. The characteristics of the spacecraft systems must be matched with the autonomous algorithm characteristics to reliably monitor and control the system. This presents a large system engineering problem. Recent work on product-focused, elegant system engineering will be applied to this application, looking at the full autonomy stack, the matching of autonomous systems to spacecraft systems, and the integration of different types of algorithms. Each of these areas will be outlined and a general approach defined for system engineering to provide the optimal solution to the given application context.

Interprofessional collaboration in the ICU: how to define?

PubMed

Rose, Louise

2011-01-01

The intensive care unit (ICU) is a dynamic, complex and, at times, highly stressful work environment that involves ongoing exposure to the complexities of interprofessional team functioning. Failures of communication, considered examples of poor collaboration among health care professionals, are the leading cause of inadvertent harm across all health care settings. Evidence suggests effective interprofessional collaboration results in improved outcomes for critically ill patients. One recent study demonstrated a link between low standardized mortality ratios and self-identified levels of collaboration. The aim of this paper is to discuss determinants and complexities of interprofessional collaboration, the evidence supporting its impact on outcomes in the ICU, and interventions designed to foster better interprofessional team functioning. Elements of effective interprofessional collaboration include shared goals and partnerships including explicit, complementary and interdependent roles; mutual respect; and power sharing. In the ICU setting, teams continually alter due to large staff numbers, shift work and staff rotations through the institution. Therefore, the ideal 'unified' team working together to provide better care and improve patient outcomes may be difficult to sustain. Power sharing is one of the most complex aspects of interprofessional collaboration. Ownership of specialized knowledge, technical skills, clinical territory, or even the patient, may produce interprofessional conflict when ownership is not acknowledged. Collaboration by definition implies interdependency as opposed to autonomy. Yet, much nursing literature focuses on achievement of autonomy in clinical decision-making, cited to improve job satisfaction, retention and patient outcomes. Autonomy of health care professionals may be an inappropriate goal when striving to foster interprofessional collaboration. Tools such as checklists, guidelines and protocols are advocated, by some, as ways for nurses to gain influence and autonomy in clinical decision-making. Protocols to guide ICU practices such as sedation and weaning reduce the duration of mechanical ventilation in some studies, while others have failed to demonstrate this advantage. Existing organizational strategies that facilitate effective collaboration between health care professionals may contribute to this lack of effect.

Effective teamwork is necessary for optimal patient care. There is insufficient understanding of interactions between physicians and nurses on internal medicine wards. To describe resident physicians' and nurses' actual behaviours contributing to teamwork quality in the setting of a simulated internal medicine ward. A volunteer sample of 14 pairs of residents and nurses in internal medicine was asked to manage one non-urgent and one urgent clinical case in a simulated ward, using a high-fidelity manikin. After the simulation, participants attended a stimulated-recall session during which they viewed the videotape of the simulation and explained their actions and perceptions. All simulations were transcribed, coded, and analyzed, using a qualitative method (template analysis). Quality of teamwork was assessed, based on patient management efficiency and presence of shared management goals and of team spirit. Most resident-nurse pairs tended to interact in a traditional way, with residents taking the leadership and nurses executing medical prescriptions and assuming their own specific role. They also demonstrated different types of interactions involving shared responsibilities and decision making, constructive suggestions, active communication and listening, and manifestations of positive team building. The presence of a leader in the pair or a truly shared leadership between resident and nurse contributed to teamwork quality only if both members of the pair demonstrated sufficient autonomy. In case of a lack of autonomy of one member, the other member could compensate for it, if his/her own autonomy was sufficiently strong and if there were demonstrations of mutual listening, information sharing, and positive team building. Although they often relied on traditional types of interaction, residents and nurses also demonstrated readiness for increased sharing of responsibilities. Interprofessional education should insist on better redefinition of respective roles and reinforce behaviours shown to enhance teamwork quality.

The adaptive potential of video guidance technology for earth orbital and interplanetary missions was explored. The application of video acquisition, pointing, tracking, and navigation technology was considered to three primary missions: planetary landing, earth resources satellite, and spacecraft rendezvous and docking. It was found that an imaging system can be mechanized to provide a spacecraft or satellite with a considerable amount of adaptability with respect to its environment. It also provides a level of autonomy essential to many future missions and enhances their data gathering ability. The feasibility of an autonomous video guidance system capable of observing a planetary surface during terminal descent and selecting the most acceptable landing site was successfully demonstrated in the laboratory. The techniques developed for acquisition, pointing, and tracking show promise for recognizing and tracking coastlines, rivers, and other constituents of interest. Routines were written and checked for rendezvous, docking, and station-keeping functions.

SMART-1 is the first of a series of ESA Small Missions for Advance Research and Technology where elements of the platform and the payload technology have been conceived as a demonstration for future cornerstone missions and an early opportunity for science. SMART-1 has also been an opportunity to experiment with new ways of conducting ground operations taking advantage of both increased satellite autonomy and ground automation tools. The paper will focus on three areas: The accumulated performance of the technology demonstration components since launch as the electrical propulsion engine, the triple-junction solar cells, the lithium-ion batteries, the 32 bit CPU ERC32 Single Chip, the CAN bus, the DTU Star Trackers and the complex on-board autonomy. The changes implemented on-board and on the ground during the lunar phase to increase the data return. The pros and contras in some of the choices made for SMART-1, the developments and solutions implemented to mitigate the problems, the tools developed to automate the operations and the distribution of data.

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

PubMed

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.

A cross-cultural comparison of the coexistence and domain superiority of individuating and relating autonomy.

PubMed

Yeh, Kuang-Hui; Bedford, Olwen; Yang, Yung-Jui

2009-06-01

The consensus definition of autonomy in the psychological literature emphasizes self-governance through free volition, not separation or independence from others. Since the concept of self may differ cross-culturally, several researchers have tried to incorporate types of self into the notion of autonomy; however, only the dual model of autonomy has been able to do this while retaining an emphasis on volition. The dual model describes two distinct forms of autonomy-individuating and relating-each with superior function in a specific domain of individual functioning. Individuating autonomy represents a volitional capacity to act against social constraints and offers a route to achieve an independent self-identity by expressing individualistic attributes and distinctions. Relating autonomy represents a volitional capacity to act by emphasizing the harmony of self-in-relation-to-others, the quality of interpersonal relationships, and self-transcendence. These two forms of autonomy have been shown to coexist at the individual level in a Taiwanese sample. This study takes the next step, with a cross-cultural test of the coexistence and domain superiority hypotheses of individuating and relating autonomy. Participants included 306 college students from Taiwan and 183 college students from the United States. Structural equation modelling by multigroup analyses confirmed the cross-cultural equivalence of the two-factor individuating autonomy and relating autonomy measurement model. Across both samples the two forms of autonomy were shown to be mutually inclusive and not exclusive or independent. The domain-superior function of each form of autonomy was also confirmed cross-culturally; each form of autonomy has a dominant, but not necessarily exclusive, domain of functioning. Specifically, individuating autonomy was more associated with intrapersonal than interpersonal domain dependent variables, while relating autonomy was more associated with interpersonal than intrapersonal domain dependent variables. Limitations of the study and considerations for future research are discussed.

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.

Respect for rational autonomy.

PubMed

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.

Autonomy and the principle of respect for autonomy.

PubMed

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.

Between government policy, clinical autonomy, and market demands: a qualitative study of the impact of the Prescribing Analysis System on behavior of physicians in South Korea.

Kim, Dong-Sook; Bae, Green; Yoo, Soo Yeon; Kang, Minah

2015-09-21

In South Korea, the Health Insurance Review and Assessment Service manages the Prescribing Analysis System (PAS) to evaluate the appropriate use of medication. To achieve the system's goal of changing prescribing behavior, it is critical to understand how physicians respond to the PAS. This study analyzes the opinions of South Korean physicians about the PAS, the way it is used, and factors affecting prescribing behavior. A qualitative, exploratory approach was used, with four focus groups of physicians from different specialties. A semi-structured guide was used to explore their opinions. Transcripts of the discussions were analyzed by the authors, who independently considered content using uniform categories. Common themes were extracted and used to gather results and draw conclusions. Physicians acknowledged some positive aspects of the PAS but, overall, had mainly negative impressions of the system, and particularly, the evaluation reports that it generates. They reported that their prescribing behavior was affected by predisposing factors, including experiential, environmental and psychological factors. Physicians reported that their negative perceptions regarding the regulations were primarily influenced by concerns about maintaining their autonomy and expertise. However, their strong resistance to these perceived infringements on their independence may be considered inconsistent in relation to their professional autonomy as there was an equally strong concern about market competition. Physicians' objections to the PAS are more likely to have been caused by deeply rooted distrust of the government agency in charge of the system. Interestingly, we found that physicians' strong resistance to perceived violations of their autonomy seems somewhat inconsistent and contradictory. While they are very positive about new information or printed materials provided by pharmaceutical representatives, they are less enthusiastic when it comes to governmental guidelines or standards. Similarly, they appear to willingly accept situations in which they believe they should comply with patients' demands as a means of surviving in a competitive market. It is notable that physicians' negative perceptions of PAS seemed to be aggravated by suspicion and distrust regarding the purpose of this program. Because of widespread beliefs in professional autonomy, market competition, and a deep-seated distrust of the system, it would be difficult for the government to persuade physicians to change their prescribing behaviors using only the PAS. Successful implementation of the PAS will not only require its improvement as a policy tool, but also the creation of a social consensus regarding the PAS.

Between professional autonomy and economic orientation - The medical profession in a changing health care system.

PubMed

Kälble, Karl

2005-02-17

The current discussions surrounding the German health care system are being determined and defined by the concepts of "profitability", "efficiency" and "saving". These concepts also determine the demands made on this system and have had an effect on the medical profession. The economy's growing influence on physicians' decision-making and the increasing necessity to look at and regulate services under economic aspects arising from the need to save costs are seen by the medical profession as a threat to its autonomous conduct and freedom to make decisions, in other words it sees it as a danger to its medical orientation. Conflicts between medical autonomy and economic orientation in physicians' conduct are therefore already foreseeable, as are conflicts between medicine and economy in regards to who has the power to define the terms of the public health system. This article will outline the area of conflict based on the available literature. It will discuss how the political and economic regulatory attempts affect the medical profession's autonomous conduct. It will also discuss which conflicts of conduct emerge for physicians, what types of solutions the medical profession tends to develop as a reaction, and whether or not this tension between medical and economic orientation can be resolved in an acceptable way. This article should first outline the changed economic and political basic conditions and the attempts to reform the German health care system, using this as a starting point. Following this, it will explore the significance professional autonomy acquires within the concept of profession from the point of view of the sociology of professions. With this in mind, the third part of this article will describe and analyze the effects of advanced economization on the medical profession's autonomous conduct, which has long been regarded as uncontested. This part of the article will also describe and analyze the medical profession's strategies it uses to defend its autonomy. Finally, this article will discuss whether or not a stronger integration of medical and economic responsibility is possible. Conclusion and summary: The conclusion that will be drawn from this discussion is that the medical profession can only avoid the pending loss of its autonomy (deprofessionalization) if it is able to combine cost efficiency and quality (and integrate economic aspects into its actions). If it is unable to do so, it will lose more and more control over the public health system to the state, economy, and management.

Concern over the limited intravehicular activity time has increased the interest in performing in-space assembly and construction operations with automated robotic systems. A technique being considered at LaRC is a supervised-autonomy approach, which can be monitored by an Earth-based supervisor that intervenes only when the automated system encounters a problem. A test-bed to support evaluation of the hardware and software requirements for supervised-autonomy assembly methods was developed. This report describes the design of the software system necessary to support the assembly process. The software is hierarchical and supports both automated assembly operations and supervisor error-recovery procedures, including the capability to pause and reverse any operation. The software design serves as a model for the development of software for more sophisticated automated systems and as a test-bed for evaluation of new concepts and hardware components.

2016-01-01

As part of the Air Force - NASA Bi-Annual Research Council Meeting, slides will be presented on recent Reduced Crew Operations (RCO) work. Unmanned aerial systems, robotics, advanced cockpits, and air traffic management are all examples of domains that are seeing dramatic increases in automation. While automation may take on some tasks previously performed by humans, humans will still be required, for the foreseeable future, to remain in the system. The collaboration with humans and these increasingly autonomous systems will begin to resemble cooperation between teammates, rather than simple task allocation. It is critical to understand this human-autonomy teaming (HAT) to optimize these systems in the future. One methodology to understand HAT is by identifying recurring patterns of HAT that have similar characteristics and solutions. A methodology for identifying HAT patterns to an advanced cockpit project is discussed.

A safety-based decision making architecture for autonomous systems

NASA Technical Reports Server (NTRS)

Musto, Joseph C.; Lauderbaugh, L. K.

1991-01-01

Engineering systems designed specifically for space applications often exhibit a high level of autonomy in the control and decision-making architecture. As the level of autonomy increases, more emphasis must be placed on assimilating the safety functions normally executed at the hardware level or by human supervisors into the control architecture of the system. The development of a decision-making structure which utilizes information on system safety is detailed. A quantitative measure of system safety, called the safety self-information, is defined. This measure is analogous to the reliability self-information defined by McInroy and Saridis, but includes weighting of task constraints to provide a measure of both reliability and cost. An example is presented in which the safety self-information is used as a decision criterion in a mobile robot controller. The safety self-information is shown to be consistent with the entropy-based Theory of Intelligent Machines defined by Saridis.

Space/ground systems as cooperating agents

Grant, T. J.

1994-01-01

Within NASA and the European Space Agency (ESA) it is agreed that autonomy is an important goal for the design of future spacecraft and that this requires on-board artificial intelligence. NASA emphasizes deep space and planetary rover missions, while ESA considers on-board autonomy as an enabling technology for missions that must cope with imperfect communications. ESA's attention is on the space/ground system. A major issue is the optimal distribution of intelligent functions within the space/ground system. This paper describes the multi-agent architecture for space/ground systems (MAASGS) which would enable this issue to be investigated. A MAASGS agent may model a complete spacecraft, a spacecraft subsystem or payload, a ground segment, a spacecraft control system, a human operator, or an environment. The MAASGS architecture has evolved through a series of prototypes. The paper recommends that the MAASGS architecture should be implemented in the operational Dutch Utilization Center.

The moral agency of institutions: effectively using expert nurses to support patient autonomy.

PubMed

Charles, Sonya

2017-08-01

Patient autonomy-with an emphasis on informed consent and the right to refuse treatment-is a cornerstone of modern bioethics. Within discussions about patient autonomy, feminist bioethicists have argued for a relational approach to autonomy. Under a relational framework, we must look beyond the individual moment of choice to include the role relationships and specific contexts can play in supporting or undermining autonomy. Given the day-to-day interactions they have with patients, nurses play a significant role in helping patients understand the nature of their illnesses and make truly informed decisions. However, the skills of expert nurses also support patient autonomy in more subtle ways. Specifically, nurses develop skills of attunement that help them to find subtle ways to support patient autonomy. However, in order to effectively do this, nurses need institutions that support their professional autonomy. In this paper, I look at the ways nurses have been inhibited in their professional autonomy both as a profession and as individual practitioners. I argue that turning our attention to institutions and the role they play in supporting or undermining nurses' autonomy can help promote nurses' professional autonomy and thereby enhance patient autonomy.

Public Health Autonomy: A Critical Reappraisal.

PubMed

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.

Analysis of the plugging of the systems autonomy demonstration project brassboard filters

NASA Technical Reports Server (NTRS)

Clay, John C.

1989-01-01

A fine gray powder was clogging the brassboard filters. The powder appeared to be residue from a galvanic corrosive attack by ammonia of the aluminum and stainless steel components in the system. The corrosion was caused by water and chlorine that had entered into the system and combined with the ammonia. This combination made an electrolyte and a corrosive agent of the ammonia that attacked the metals in the system. The corroded material traveled through the system with the ammonia and clogged the filters. Key conclusions are: the debris collecting in the filters is a by-product of galvanic corrosion; the debris is principally corroded aluminum and stainless from the system; and galvanic corrosion occurred from water and chlorine that entered the system during normal and/or extreme operating and servicing conditions. Key recommendations are: use only one metal in the ammonia system-titanium, aluminum, or stainless steel; make the system as air-tight as possible (replace fittings with welded joints); and replace electron paramagnetic resonance (EPR) O-rings with neoprene O-rings, and do not use freon to clean system components.

Lanza, H. Isabella; Huang, David Y. C.; Murphy, Debra A.; Hser, Yih-Ing

2013-01-01

The present study sought to extend empirical inquiry related to the role of parenting on adolescent sexual risk-taking by using latent class analysis (LCA) to identify patterns of adolescent-reported mother responsiveness and autonomy-granting in early adolescence and examine associations with sexual risk-taking in mid- and late-adolescence. Utilizing a sample of 12- to 14-year-old adolescents (N = 4,743) from the 1997 National Longitudinal Survey of Youth (NLSY97), results identified a four-class model of maternal responsiveness and autonomy-granting: low responsiveness/high autonomy-granting, moderate responsiveness/moderate autonomy-granting, high responsiveness/low autonomy-granting, high responsiveness/moderate autonomy-granting. Membership in the low responsiveness/high autonomy-granting class predicted greater sexual risk-taking in mid- and late-adolescence compared to all other classes, and membership in the high responsiveness/ moderate autonomy-granting class predicted lower sexual risk-taking. Gender and ethnic differences in responsiveness and autonomy-granting class membership were also found, potentially informing gender and ethnic disparities of adolescent sexual risk-taking.

Patient Autonomy for the Management of Chronic Conditions: A Two-Component Re-conceptualization

PubMed Central

Naik, Aanand D.; Dyer, Carmel B.; Kunik, Mark E.; McCullough, Laurence B.

2010-01-01

The clinical application of the concept of patient autonomy has centered on the ability to deliberate and make treatment decisions (decisional autonomy) to the virtual exclusion of the capacity to execute the treatment plan (executive autonomy). However, the one-component concept of autonomy is problematic in the context of multiple chronic conditions. Adherence to complex treatments commonly breaks down when patients have functional, educational, and cognitive barriers that impair their capacity to plan, sequence, and carry out tasks associated with chronic care. The purpose of this article is to call for a two-component re-conceptualization of autonomy and to argue that the clinical assessment of capacity for patients with chronic conditions should be expanded to include both autonomous decision making and autonomous execution of the agreed-upon treatment plan. We explain how the concept of autonomy should be expanded to include both decisional and executive autonomy, describe the biopsychosocial correlates of the two-component concept of autonomy, and recommend diagnostic and treatment strategies to support patients with deficits in executive autonomy.

A longitudinal research on the development of emotional autonomy during adolescence.

PubMed

Parra, Agueda; Oliva, Alfredo

2009-05-01

The purpose of the present paper was to study the development of emotional autonomy through adolescence analysing its association with family relationships. The development of emotional autonomy involves an increase in adolescents' subjective sense of his or her independence, especially in relation to parents. From some scholars emotional autonomy is a normative manifestation of the detachment process from parents, however, others point out that detachment from parental ties is not the norm, so high level of adolescent emotional autonomy is the consequence of negative family relationships. In our study a sample of 101 adolescents were followed for 5 years, from early to middle adolescence, and completed questionnaires to measure their emotional autonomy and the quality of their family relationships. Our results showed that over the course of adolescence some dimensions of emotional autonomy increase, meanwhile others decrease, so the global level of emotional autonomy global level remains stable. On the other hand, emotional autonomy is associated with negative family relationships, so emotional autonomy, more than a necessary process to become adult, could be indicating an insecure attachment to parents.

Effects of an autonomy-supportive exercise instructing style on exercise motivation, psychological well-being, and exercise attendance in middle-age women.

Moustaka, Frederiki C; Vlachopoulos, Symeon P; Kabitsis, Chris; Theodorakis, Yannis

2012-01-01

The present study evaluated the effectiveness of an autonomy-supportive intervention based on self-determination theory in influencing perceptions of autonomy support, basic psychological needs, behavioral regulations, subjective vitality, and exercise behavior. 35 female exercise participants age 30 to 58 years who enrolled to an 8-week exercise program attended 24 exercise classes that were taught using either an autonomy-supportive (n = 19) or a lack of autonomy support (n = 16) instructing style. The experimental group reported an increase in perceived autonomy support, the fulfillment of the needs for autonomy and competence, identified regulation, intrinsic motivation, and subjective vitality. They also reported higher attendance rates during the program and greater participation to moderate and/or mild nonstructured exercise during 5 weeks after the end of the program. The control group reported a decrease in perceived autonomy support, the needs for autonomy and competence, intrinsic motivation, and subjective vitality. The results supported tenets of self-determination theory and highlighted the motivational and psychological benefits of an autonomy-supportive exercise instructing style among middle-age women.

System control of an autonomous planetary mobile spacecraft

NASA Technical Reports Server (NTRS)

Dias, William C.; Zimmerman, Barbara A.

1990-01-01

The goal is to suggest the scheduling and control functions necessary for accomplishing mission objectives of a fairly autonomous interplanetary mobile spacecraft, while maximizing reliability. Goals are to provide an extensible, reliable system conservative in its use of on-board resources, while getting full value from subsystem autonomy, and avoiding the lure of ground micromanagement. A functional layout consisting of four basic elements is proposed: GROUND and SYSTEM EXECUTIVE system functions and RESOURCE CONTROL and ACTIVITY MANAGER subsystem functions. The system executive includes six subfunctions: SYSTEM MANAGER, SYSTEM FAULT PROTECTION, PLANNER, SCHEDULE ADAPTER, EVENT MONITOR and RESOURCE MONITOR. The full configuration is needed for autonomous operation on Moon or Mars, whereas a reduced version without the planning, schedule adaption and event monitoring functions could be appropriate for lower-autonomy use on the Moon. An implementation concept is suggested which is conservative in use of system resources and consists of modules combined with a network communications fabric. A language concept termed a scheduling calculus for rapidly performing essential on-board schedule adaption functions is introduced.

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

PubMed

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.

Grand Challenge Problems in Real-Time Mission Control Systems for NASA's 21st Century Missions

NASA Technical Reports Server (NTRS)

Pfarr, Barbara B.; Donohue, John T.; Hughes, Peter M.

1999-01-01

Space missions of the 21st Century will be characterized by constellations of distributed spacecraft, miniaturized sensors and satellites, increased levels of automation, intelligent onboard processing, and mission autonomy. Programmatically, these missions will be noted for dramatically decreased budgets and mission development lifecycles. Current progress towards flexible, scaleable, low-cost, reusable mission control systems must accelerate given the current mission deployment schedule, and new technology will need to be infused to achieve desired levels of autonomy and processing capability. This paper will discuss current and future missions being managed at NASA's Goddard Space Flight Center in Greenbelt, MD. It will describe the current state of mission control systems and the problems they need to overcome to support the missions of the 21st Century.

Adoption of clinical decision support systems in a developing country: Antecedents and outcomes of physician's threat to perceived professional autonomy.

PubMed

Esmaeilzadeh, Pouyan; Sambasivan, Murali; Kumar, Naresh; Nezakati, Hossein

2015-08-01

The basic objective of this research is to study the antecedents and outcomes of professional autonomy which is a central construct that affects physicians' intention to adopt clinical decision support systems (CDSS). The antecedents are physicians' attitude toward knowledge sharing and interactivity perception (about CDSS) and the outcomes are performance expectancy and intention to adopt CDSS. Besides, we include (1) the antecedents of attitude toward knowledge sharing-subjective norms, social factors and OCB (helping behavior) and (2) roles of physicians' involvement in decision making, computer self-efficacy and effort expectancy in our framework. Data from a stratified sample of 335 Malaysian physicians working in 12 public and private hospitals in Malaysia were collected to test the hypotheses using Structural Equation Modeling (SEM). The important findings of our research are: (1) factors such as perceived threat to professional autonomy, performance expectancy, and physicians' involvement in making decision about CDSS have significant impact on physicians' intention to adopt CDSS; (2) physicians' attitude toward knowledge sharing, interactivity perception and computer self-efficacy of physicians play a crucial role in influencing their perceived threat to professional autonomy; and (3) social network, shared goals and OCB (helping behavior) impact physicians' attitude toward knowledge sharing. The findings provide a comprehensive understanding of the factors that influence physicians' intention to adopt CDSS in a developing country. The results can help hospital managers manage CDSS implementation in an effective manner. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Lunar and Mars Exploration: The Autonomy Factor

NASA Technical Reports Server (NTRS)

Rando, Cynthia M.; Schuh, Susan V.

2008-01-01

Long duration space flight crews have relied heavily on almost constant communication with ground control mission support. Ground control teams provide vehicle status and system monitoring, while offering near real time support for specific tasks, emergencies, and ensuring crew health and well being. With extended exploration goals to lunar and Mars outposts, real time communication with ground control teams and the ground s ability to conduct mission monitoring will be very limited compared to the resources provided to current International Space Station (ISS) crews. An operational shift toward more autonomy and a heavier reliance on the crew to monitor their vehicle and operations will be required for these future missions. NASA s future exploration endeavors and the subsequent increased autonomy will require a shift in crew skill composition, i.e. engineer, doctor, mission specialist etc. and lead to new training challenges and mission scenarios. Specifically, operational and design changes will be necessary in many areas including: Habitat Infrastructure and Support Systems, Crew Composition, Training, Procedures and Mission Planning. This paper will specifically address how to apply ISS lessons learned to further use ISS as a test bed to address decreased amounts of ground support to achieve full autonomous operations for lunar and Mars missions. Understanding these lessons learned and applying them to current operations will help to address the future impacts of increased crew autonomy for the lunar and Mars outposts and pave the way for success in increasingly longer mission durations.

To review critically the traditional concept of autonomy, propose an alternative relational interpretation of autonomy, and discuss how this would operate in identifying and addressing ethical issues that arise in the context of nursing home care for older adults. Respect for patient autonomy has been the cornerstone of clinical bioethics for several decades. Important though this principle is, there is debate on how to interpret the core concept of autonomy. We review the appeal of the traditional approach to autonomy in health care and then identify some of the difficulties with this conception. We use philosophical methods to explain and discuss the traditional and relational conceptions of autonomy and we illuminate our discussion with examples of various contextual applications. We support the relational conception of autonomy as offering a richer, more contextualized understanding of autonomy which attends to the social, political and economic conditions that serve as background to an agent's deliberations. To illuminate these ideas, we discuss the situation of frail older adults who frequently find their autonomy limited not only by their medical conditions but also by cultural prejudices against the aged and by the conditions commonly found within the nursing homes in which many reside. We propose ways of improving the relational autonomy of this population. © 2010 Blackwell Publishing Ltd.

Objective To examine the relation of behavioral autonomy to psychological, behavioral, and physical health among emerging adults with and without type 1 diabetes. Methods High school seniors with (n = 118) and without type 1 diabetes (n = 122) completed online questionnaires for three consecutive years. Behavioral autonomy, psychological health, risk behaviors, and diabetes outcomes were assessed. Regression analyses were conducted to predict Time 2 and 3 outcomes, controlling for Time 1 outcomes. Results There were no group differences in behavioral autonomy. Behavioral autonomy predicted better psychological health but only for emerging adults without diabetes. Behavioral autonomy was related to increased risk behavior for both groups. Behavioral autonomy was unrelated to self-care but predicted better glycemic control for females. Conclusions Behavioral autonomy may be beneficial for psychological health, but is related to increased risk behavior. The implications of behavioral autonomy for emerging adults with type 1 diabetes require careful consideration. PMID:25157070

2014-12-01

Increasing attention to patient safety in training hospitals may come at the expense of trainee autonomy and professional growth. This study sought to examine changes in medical trainees' self-reported behaviour after the institution-wide implementation of a rapid response system. We conducted a two-point cross-sectional survey of medical trainees in 2006, during the implementation of a rapid response system, and in 2010, in a single academic medical centre. A novel instrument was used to measure trainee likelihood of calling for supervisory assistance, perception of autonomy, and comfort in managing decompensating patients. Non-parametric tests to assess for change were used and year of training was evaluated as an effect modifier. Response rates were 38% in 2006 and 70% in 2010. After 5 years of the full implementation of the rapid response system, residents were significantly more likely to report calling their attending physicians for assistance (rising from 40% to 65% of relevant situations; p < 0.0001). Year of training was a significant effect modifier. Interns felt significantly more comfortable in managing acutely ill patients; juniors and seniors felt significantly less concerned about their autonomy at 5 years after the implementation of the rapid response system. These changes were mirrored in the actual use of the rapid response system, which increased by 41% during the 5-year period after adjustment for patient volume (p < 0.0001). A primary team-focused implementation of a rapid response system was associated with durable changes in resident physicians' reported behaviour, including increased comfort with involving more experienced physicians and managing unstable patients. © 2014 John Wiley & Sons Ltd.

Applicability of the principle of respect for autonomy: the perspective of Turkey.

PubMed

Kara, Mahmut Alpertunga

2007-11-01

Turkey has a complex character, which has differences from the Western world or Eastern Asia as well as common points. Even after more than a century of efforts to modernise and integrate with the West, Turkish society has values that are different from those of the West, as well as having Western values. It is worth questioning whether ordinary Turkish people show an individualistic character. The principle of respect for individual autonomy arises from a perception of oneself as an individual, and the person's situation may affect the applicability of the principle. Patients who perceive themselves to be members of a community rather than free persons and who prefer to participate in the common decisions of the community and to consider the common interest and the common value system of the community concerning problems of their life (except healthcare or biomedical research) rather than to decide as independent, rational individuals may not be competent to make an autonomous choice. Expectations that such patients will behave as autonomous individuals may be unjustified. The family, rather than the patient, may take a primary role in decisions. A flexible system considering cultural differences in the concept of autonomy may be more feasible than a system following strict universal norms.

A flexible system considering cultural differences in the concept of autonomy may be more feasible than a system following strict universal norms. PMID:17971462

Ethics consultation and autonomy.

PubMed

Varelius, Jukka

2008-03-01

Services of ethics consultants are nowadays commonly used in such various spheres of life as engineering, public administration, business, law, health care, journalism, and scientific research. It has however been maintained that use of ethics consultants is incompatible with personal autonomy; in moral matters individuals should be allowed to make their own decisions. The problem this criticism refers to can be conceived of as a conflict between the professional autonomy of ethics experts and the autonomy of the persons they serve. This paper addresses this conflict and maintains that when the nature of both ethics consultation and individual autonomy is properly understood, the professional autonomy of ethics experts is compatible with the autonomy of the persons they assist.

The appearance of Kant's deontology in contemporary Kantianism: concepts of patient autonomy in bioethics.

PubMed

Secker, B

1999-02-01

Kant's concept of autonomy and the Kantian notion of autonomy are often conflated in bioethics. However, the contemporary Kantian notion has very little at all to do with Kant's original. In order to further bioethics discourse on autonomy, I critically distinguish the contemporary Kantian notion from Kant's original concept of moral autonomy. I then evaluate the practical relevance of both concepts of autonomy for use in bioethics. I argue that it is not appropriate to appeal to either concept toward assessing which patients we ought to respect as autonomous. Finally, I sketch criteria for what I take to be a more promising concept of autonomy for patients.

An intercultural nursing perspective on autonomy.

PubMed

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.

We examine relations between perceived organisational autonomy support and different types of work motivation and well-being outcomes in 266 teachers from two government schools in China. We hypothesised that greater autonomy support would be associated with more autonomous forms of employee motivation, and that teacher motivation would in turn mediate the effects of autonomy support on indicators of work well-being (i.e., job satisfaction, work stress and physical ill symptoms). Results generally supported the hypothesised relations between perceived autonomy support and SDT's five types of motivations. Findings also showed that perceived autonomy support predicted job satisfaction directly and indirectly through the mediating roles of intrinsic motivation, identified regulation, introjected regulation and external regulation. Perceived autonomy support predicted work stress directly and indirectly through the mediating roles of external regulation and amotivation. Autonomy support also predicted illness symptoms via the mediating roles of intrinsic motivation, introjected regulation and amotivation. The current findings highlight how perceived organisational support for autonomy relates to motivational differences in a Chinese work context, and the potential relevance of autonomy support for employee well-being. © 2014 International Union of Psychological Science.

Autonomy support for autonomous motivation in medical education.

PubMed

2015-01-01

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.

The aim was to study whether perceived environmental barriers to outdoor mobility affect changes in sense of autonomy in participation outdoors among community-dwelling older people over a two-year period. Community-dwelling people aged 75-90 years (n = 848) in central Finland were interviewed on two occasions, face-to-face at baseline and over the telephone two years later. Perceived environmental barriers to outdoor mobility were assessed using a 15-item structured questionnaire, and the sum scores categorized into tertiles (0, 1 and 2 or more barriers). Autonomy in participation outdoors was assessed with the 'Impact on Participation and Autonomy' (IPA) questionnaire using the autonomy outdoors subscale (score range 0-20, higher scores indicating more restricted autonomy). Scores for autonomy in participation outdoors were available for 848 participants at baseline (mean 6.2, SD = 3.8) and for 748 participants at the two-year follow-up (mean 6.7, SD = 3.9). At baseline, those reporting multiple environmental barriers had the most restricted autonomy, while those reporting no environmental barriers had the least restricted autonomy (p < .001). Over the follow-up, autonomy in participation outdoors declined more among those reporting multiple environmental barriers compared to those reporting none (age- and sex-adjusted group*time β = .629, s.e. = .277, p = .023). Adjustment for cognitive functioning, education, number of chronic conditions and change in walking difficulty did not influence the association. Perceived environmental barriers to outdoor mobility accelerate the decline in autonomy in participation outdoors among older community-dwelling people. Understanding factors affecting autonomy can help in finding ways to support the sense of autonomy as people age.

Despite various efforts for enhancing women's autonomy in developing countries, many women are deprived of their capacity in decision-making on their household affairs as well as social issues. This paper aimed to examine women's autonomy and its associated factors in the Kapilvastu district of Nepal. We measured women's autonomy using a recently developed women's autonomy measurement scale from June to October 2014. Descriptive statistics, chi-square test and logistic multivariate modeling technique were applied for assessing the association of demographic and socio-economic characteristics of women and their autonomy. Mean score for women's autonomy was 23.34 ± 8.06 out of the possible maximum 48. It was found to be positively associated with higher age difference at marriage, advantaged caste/ethnicity, better employment for the husband, couple's education more than 10 years schooling, and higher economic status of the household. We found strong direct effect of women's education (OR = 8.14, CI = 3.77-17.57), husband's education (OR = 2.63, CI = 1.69-4.10) and economic status of household (OR = 1.42, CI = 1.01-2.03) on women's autonomy. When we adjusted women's education for husband's education, the odds ratio decreased by around 22% {from (OR = 8.14, CI = 3.77-17.57) to (OR = 6.32, CI = 2.77-14.46)} and was a mediator effect. The economic status of household also had mediator effect on women's autonomy through their education. Education status of women is a key predictor of women's autonomy in Kapilvastu district. Husband's education and economic status of the household are other important predictors of women's autonomy which have a mediator effect on women's autonomy. Improving educational status and economic conditions of both women and their husbands may be the best solution to promote women's autonomy.

Silva, Silvio Fernandes da; Souza, Nathan Mendes; Barreto, Jorge Otávio Maia

2014-11-01

The scope of this article was to identify the boundaries of the autonomy of local administration in the context of the federal pact in the Brazilian Unified Health System and the importance and potential for promoting innovation, creativity and evidence-based decision-making by local governments. The methodology used was to ask questions that favored dialogue with the specific literature to identify the influence of centrally-formulated policies in spaces of local autonomy and then to identify strategies to foster innovation, creativity and the systematic use of evidence-based research in health policy implementation. A gradual reduction in municipal decision-making autonomy was detected due to increased financial commitment of the municipalities resulting from responsibilities assumed, albeit with the possibility of reverting this trend in the more recent context. Some determinants and challenges for the dissemination of innovative practices were analyzed and some relevant national and international experiences in this respect were presented. The conclusion drawn is that it is possible to make local decision-making more effective provided that initiatives are consolidated to promote this culture and the formulation and implementation of evidence-based health policies.

Legal leverage is broadly defined as the use of legal authority to promote treatment adherence. It is widely utilized within mental health courts, drug courts, mandated outpatient treatment programs, and other intervention strategies for individuals with mental illness or chemical dependency who have contact with the criminal justice system. Nonetheless, the ethics of using legal authority to promote treatment adherence remains a hotly debated issue within public and professional circles alike. While critics characterize legal leverage as a coercive form of social control that undermines personal autonomy, advocates contend that it supports autonomy because treatment strategies using legal leverage are designed to promote health and independence. Despite the controversy, there is little evidence regarding the impact of legal leverage on patient autonomy as experienced and expressed by patients themselves. This report presents findings from a qualitative study involving six focus groups with severely mentally ill outpatients who received legal leverage through three forensic assertive community treatment (FACT) programs in Northeastern, Midwestern, and West Coast cities. Findings are discussed in the context of the self-determination theory of human motivation, and practical implications for the use of legal leverage are considered.

Aging is an inevitable process that has a social impact in the forecoming decades, and it will present a great challenge regarding public health. An efficient health system requires a reflection on the preventive measures to be implemented. The study population comprised a total number of 2672 individuals of both genders, aged 55 years and over, residents in continental Portugal, to whom a questionnaire was applied that included the following sections: Social network; Locomotion; Physical autonomy; Instrumental autonomy; Cognitive assessment; Physical activity. The study of aging in the Portuguese population found that physical autonomy for tasks related to daily life are associated with better cognitive evaluation. A statistically significant association was found between performance in cognitive assessment and gender, age, schooling, the fact of living alone, the number of hours being alone, autonomy to walk in the street, washing, dressing, eating, preparing meals, doing shopping, managing money and taking medications and washer / treat clothing. Cognitive evaluation is negatively influenced by the number of hours that an individual is alone. Activities of daily life must be valued, since they require the ability to plan and carry out tasks and their preservation is a key component in successful aging.

2007-01-01

Background Functional status or disability forms the core of most assessment instruments used to identify mix and level of resources and services needed by older adults who possess common characteristics. The Functional Autonomy Measurement System (SMAF) is a 29-item scale measuring functional ability in five different areas. It has been recommended for use for home care, for allocation of chronic beds, for developing care plans in institutional settings and for epidemiological and evaluative studies. The SMAF can also be used with a case-mix classification system (Iso-SMAF) to allocate resources based on patients' functional autonomy characteristics. The objective of this project was to develop a software version of the SMAF to facilitate the evaluation of the functional status of older adults in health services research and to optimize the clinical decision-making process. Results The eSMAF was developed over an 24-month period using a modified waterfall software engineering process. Requirements and functional specifications were determined using focus groups of stakeholders. Different versions of the software were iteratively field-tested in clinical and research environments and software adaptations made accordingly. User documentation and online help were created to assist the deployment of the software. The software is available in French or English versions under a 30-day unregistered demonstration license or a free restricted registered academic license. It can be used locally on a Windows-based PC or over a network to input SMAF data into a database, search and aggregate client data according to clinical and/or administrative criteria, and generate summary or detailed reports of selected data sets for print or export to another database. Conclusion In the last year, the software has been successfully deployed in the clinical workflow of different institutions in research and clinical applications. The software performed relatively well in terms of stability and performance. Barriers to implementation included antiquated computer hardware, low computer literacy and access to IT support. Key factors for the deployment of the software included standardization of the workflow, user training and support. PMID:17298673

Robotic-assisted laparoscopic radical nephrectomy using the Da Vinci Si system: how to improve surgeon autonomy. Our step-by-step technique.

Davila, Hugo H; Storey, Raul E; Rose, Marc C

2016-09-01

Herein, we describe several steps to improve surgeon autonomy during a Left Robotic-Assisted Laparoscopic Radical Nephrectomy (RALRN), using the Da Vinci Si system. Our kidney cancer program is based on 2 community hospitals. We use the Da Vinci Si system. Access is obtained with the following trocars: Two 8 mm robotic, one 8 mm robotic, bariatric length (arm 3), 15 mm for the assistant and 12 mm for the camera. We use curved monopolar scissors in robotic arm 1, Bipolar Maryland in arm 2, Prograsp Forceps in arm 3, and we alternate throughout the surgery with EndoWrist clip appliers and the vessel sealer. Here, we described three steps and the use of 3 robotic instruments to improve surgeon autonomy. Step 1: the lower pole of the kidney was dissected and this was retracted upwards and laterally. This maneuver was performed using the 3rd robotic arm with the Prograsp Forceps. Step 2: the monopolar scissors was replaced (robotic arm 1) with the robotic EndoWrist clip applier, 10 mm Hem-o-Lok. The renal artery and vein were controlled and transected by the main surgeon. Step 3: the superior, posterolateral dissection and all bleeders were carefully coagulated by the surgeon with the EndoWrist one vessel sealer. We have now performed 15 RALRN following these steps. Our results were: blood loss 300 cc, console time 140 min, operating room time 200 min, anesthesia time 180 min, hospital stay 2.5 days, 1 incisional hernia, pathology: (13) RCC clear cell, (1) chromophobe and (1) papillary type 1. Tumor Stage: (5) T1b, (8) T2a, (2) T2b. We provide a concise, step-by-step technique for radical nephrectomy (RN) using the Da Vinci Si robotic system that may provide more autonomy to the surgeon, while maintaining surgical outcome equivalent to standard laparoscopic RN.

In the company of women: enacting autonomy within the perinatal nursing relationship.

An understanding of autonomy has important significance in North American health care. Although a respect for autonomy is necessary to protect the self-determination and agency of birthing women in hospital settings, I suggest that enactments of autonomy that are independent of relationships offer only an incomplete interpretation of such a vital concept. In this article I explore an understanding of autonomy situated within the context of a relational birthing narrative. In so doing, autonomy becomes conceptualized as contextual and concrete, giving rise to an embodied view of the birthing woman.

The ground-based demonstrations of Extra Vehicular Activity (EVA) Retriever, a voice-supervised, intelligent, free-flying robot, are designed to evaluate the capability to retrieve objects (astronauts, equipment, and tools) which have accidentally separated from the Space Station. The EVA Retriever software is required to autonomously plan and execute a target rendezvous, grapple, and return to base while avoiding stationary and moving obstacles with subsequent object handover. The software architecture incorporates a heirarchical decomposition of the control system that is horizontally partitioned into five major functional subsystems: sensing, perception, world model, reasoning, and acting. The design provides for supervised autonomy as the primary mode of operation. It is intended to be an evolutionary system improving in capability over time and as it earns crew trust through reliable and safe operation. This paper gives an overview of the hardware, a focus on software, and a summary of results achieved recently from both computer simulations and air bearing floor demonstrations. Limitations of the technology used are evaluated. Plans for the next phase, during which moving targets and obstacles drive realtime behavior requirements, are discussed.

An emerging body of research is focusing on understanding and building artificial systems that can achieve open-ended development influenced by intrinsic motivations. In particular, research in robotics and machine learning is yielding systems and algorithms with increasing capacity for self-directed learning and autonomy. Traditional software architectures and algorithms are being augmented with intrinsic motivations to drive cumulative acquisition of knowledge and skills. Intrinsic motivations have recently been considered in reinforcement learning, active learning and supervised learning settings among others. This paper considers game theory as a novel setting for intrinsic motivation. A game theoretic framework for intrinsic motivation is formulated by introducing the concept of optimally motivating incentive as a lens through which players perceive a game. Transformations of four well-known mixed-motive games are presented to demonstrate the perceived games when players' optimally motivating incentive falls in three cases corresponding to strong power, affiliation and achievement motivation. We use agent-based simulations to demonstrate that players with different optimally motivating incentive act differently as a result of their altered perception of the game. We discuss the implications of these results both for modeling human behavior and for designing artificial agents or robots. PMID:24198797

Model Based Autonomy for Robust Mars Operations

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.

An architecture of interoperating agents has been developed to provide control and fault management for advanced life support systems in space. In this adjustable autonomy architecture, software agents coordinate with human agents and provide support in novel fault management situations. This architecture combines the Livingstone model-based mode identification and reconfiguration (MIR) system with the 3T architecture for autonomous flexible command and control. The MIR software agent performs model-based state identification and diagnosis. MIR identifies novel recovery configurations and the set of commands required for the recovery. The AZT procedural executive and the human operator use the diagnoses and recovery recommendations, and provide command sequencing. User interface extensions have been developed to support human monitoring of both AZT and MIR data and activities. This architecture has been demonstrated performing control and fault management for an oxygen production system for air revitalization in space. The software operates in a dynamic simulation testbed.

A Physician's Perspective On Vertical Integration.

PubMed

Berenson, Robert A

2017-09-01

Vertical integration has been a central feature of health care delivery system change for more than two decades. Recent studies have demonstrated that vertically integrated health care systems raise prices and costs without observable improvements in quality, despite many theoretical reasons why cost control and improved quality might occur. Less well studied is how physicians view their newfound partnerships with hospitals. In this article I review literature findings and other observations on five aspects of vertical integration that affect physicians in their professional and personal lives: patients' access to physicians, physician compensation, autonomy versus system support, medical professionalism and culture, and lifestyle. I conclude that the movement toward physicians' alignment with and employment in vertically integrated systems seems inexorable but that policy should not promote such integration either intentionally or inadvertently. Instead, policy should address the flaws in current payment approaches that reward high prices and excessive service use-outcomes that vertical integration currently produces.

Development of an evolutionary simulator and an overall control system for intelligent wheelchair

NASA Astrophysics Data System (ADS)

Imai, Makoto; Kawato, Koji; Hamagami, Tomoki; Hirata, Hironori

The goal of this research is to develop an intelligent wheelchair (IWC) system which aids an indoor safe mobility for elderly and disabled people with a new conceptual architecture which realizes autonomy, cooperativeness, and a collaboration behavior. In order to develop the IWC system in real environment, we need design-tools and flexible architecture. In particular, as more significant ones, this paper describes two key techniques which are an evolutionary simulation and an overall control mechanism. The evolutionary simulation technique corrects the error between the virtual environment in a simulator and real one in during the learning of an IWC agent, and coevolves with the agent. The overall control mechanism is implemented with subsumption architecture which is employed in an autonomous robot controller. By using these techniques in both simulations and experiments, we confirm that our IWC system acquires autonomy, cooperativeness, and a collaboration behavior efficiently.

The Autonomous Urban Reconnaissance Ingress System (AURIS™) addresses a significant limitation of current military and first responder robotics technology: the inability of reconnaissance robots to open doors. Leveraging user testing as a baseline, the program has derived specifications necessary for military personnel to open doors with fielded UGVs (Unmanned Ground Vehicles), and evaluates the technology's impact on operational mission areas: duration, timing, and user patience in developing a tactically relevant, safe, and effective system. Funding is provided through the US ARMY Tank Automotive Research, Development and Engineering Center (TARDEC) and the project represents a leap forward in perception, autonomy, robotic implements, and coordinated payload operation in UGVs. This paper describes high level details of specification generation, status of the last phase of development, an advanced view of the system autonomy capability, and a short look ahead towards the ongoing work on this compelling and important technology.

This paper describes experience using Obstacle Analysis to identify contingency requirements on an unpiloted aerial vehicle. A contingency is an operational anomaly, and may or may not involve component failure. The challenges to this effort were: ( I ) rapid evolution of the system while operational, (2) incremental autonomy as capabilities were transferred from ground control to software control and (3) the eventual safety-criticality of such systems as they begin to fly over populated areas. The results reported here are preliminary but show that Obstacle Analysis helped (1) identify new contingencies that appeared as autonomy increased; (2) identify new alternatives for handling both previously known and new contingencies; and (3) investigate the continued validity of existing software requirements for contingency handling. Since many mobile, intelligent systems are built using a development process that poses the same challenges, the results appear to have applicability to other similar systems.

This study aims to construct an index of women's autonomy to analyze its effect on maternal healthcare utilization in Bangladesh. Empirical modeling of the study used instrumental variable (IV) approach to correct for possible endogeneity of women's autonomy variable. Data from the Bangladesh Demographic and Health Survey (BDHS) 2011 was used for the study. Women's autonomy variable was obtained through factor analysis of variables related to autonomy in decision making regarding healthcare, financial autonomy and freedom of movement. Conditional mixed process (CMP) models were fitted for three maternal healthcare indicators: at least four antenatal care (ANC) by trained personnel, institutional delivery and postnatal care (PNC) by trained personnel. Study sample consisted of 8753 women with 5.5 mean years of schooling. Women with no formal education, of Islamic faith, from poorest wealth quintile, residing in rural areas and with low autonomy used the maternal healthcare least. Marginal effect shows that if women's autonomy score is increased by one unit, probability of maternal healthcare utilization will increase by 0.14 for ANC, 0.14 for institutional delivery, and 0.13 for PNC. Women's autonomy is an important driver of maternal healthcare utilization in Bangladesh. Results suggest that women participating in social and economic activities enhances their autonomy. Other factors affecting women's autonomy are female literacy, educational attainment and households' economic status. Copyright © 2017 Elsevier B.V. All rights reserved.

One of the important factors in the prediction of family planning outcome is paying attention to women's role in decision making concerning fertility and household affairs. With the improvement of women's status and autonomy, their control over fertility is expected to increase. The present study aimed to investigate the association between women's autonomy and family planning outcome of the couples residing in Isfahan. This is cross-sectional study. Two hundred and seventy women of childbearing age, eligible for family planning and residing in Isfahan, were selected through random cluster sampling and they filled a researcher-made questionnaire. Women's autonomy was measured with the questions on their decision-making autonomy concerning household affairs and physical mobility autonomy. The association between women's autonomy and family planning outcome was analyzed through statistical methods. The results showed that the mean of women's decision-making, physical mobility, and general autonomy was 50. Women's autonomy had a direct significant association with the type of contraception method (P = 0.01) and the length of usage of their present contraception method (P = 0.04) as well as where they received family planning services (P = 0.02). Analysis of data revealed women with higher autonomy used a more efficient contraception method and continued their contraception method for a longer time, which leads to improvement of couples' family planning outcome. Therefore, family planning services should be planned and provided with women's autonomy under consideration.

Autonomy gone awry: a cross-cultural study of parents' experiences in neonatal intensive care units.

PubMed

Orfali, Kristina; Gordon, Elisa J

2004-01-01

This paper examines parents' experiences of medical decision-making and coping with having a critically ill baby in the Neonatal Intensive Care Unit (NICU) from a cross-cultural perspective (France vs. U.S.A.). Though parents' experiences in the NICU were very similar despite cultural and institutional differences, each system addresses their needs in a different way. Interviews with parents show that French parents expressed overall higher satisfaction with the care of their babies and were better able to cope with the loss of their child than American parents. Central to the French parents' perception of autonomy and their sense of satisfaction were the strong doctor-patient relationship, the emphasis on medical certainty in prognosis versus uncertainty in the American context, and the "sentimental work" provided by the team. The American setting, characterized by respect for parental autonomy, did not necessarily translate into full parental involvement in decision-making, and it limited the rapport between doctors and parents to the extent of parental isolation. This empirical comparative approach fosters a much-needed critique of philosophical principles by underscoring, from the parents' perspective, the lack of "emotional work" involved in the practice of autonomy in the American unit compared to the paternalistic European context. Beyond theoretical and ethical arguments, we must reconsider the practice of autonomy in particularly stressful situations by providing more specific means to cope, translating the impersonal language of "rights" and decision-making into trusting, caring relationships, and sharing the responsibility for making tragic choices.

Interpersonal sensitivity is a depression-prone personality trait closely related to anxious attachment, whereas sociotropy and autonomy are personality vulnerability factors in the cognitive theory of depression. In the present study, the relationships of interpersonal sensitivity with sociotropy and autonomy were studied in 362 healthy subjects. Interpersonal sensitivity was assessed using the Interpersonal Sensitivity Measure (IPSM), whereas sociotropy and autonomy were evaluated using the Sociotropy and Autonomy subscales, respectively, of the Sociotropy-Autonomy Scale. The IPSM was significantly correlated with the Sociotropy subscale (β = 0.61, p < 0.001) but not with the Autonomy subscale. All subscales of the IPSM correlated significantly with the Sociotropy subscale, and the correlation for the Separation Anxiety subscale (β = 0.56, p < 0.001) was strongest. The present study suggests that interpersonal sensitivity is correlated with sociotropy but not with autonomy in healthy subjects.

Collectivists' contingency and autonomy as predictors of buffet preferences among Taiwanese adolescents.

PubMed

Chiou, Wen-Bin

2006-01-01

In a culture or society with high collectivism, contingent orientation and constrained autonomy are the prominent characteristics of adolescents' self-construal. This article examined whether Taiwanese adolescents' contingency and autonomy were associated with their prevalent preferences for buffet consumption. Findings in a panel survey indicated that contingency was positively correlated with adolescents' buffet preference, whereas autonomy was negatively correlated. Moreover, the results showed that adolescents' contingent orientation and perceived autonomy could predict their subsequent buffet preference over a half-year period. A laboratory experiment showed that adolescents who perceived lower autonomy exhibited greater preferences for buffet over the other diet consumption. In general, the results suggest that collectivist adolescents' contingency and autonomy were related to their trait-like preferences for buffet, and the state-like preferences for buffet were affected by their perceived levels of autonomy. Findings provide further insights into the impact of adolescents' self-construal on their diet consumption.

Autonomy and autonomy competencies: a practical and relational approach.

PubMed

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.

Human involvement with increasingly autonomous systems must adjust to allow for a more dynamic relationship involving cooperation and teamwork. As part of an ongoing project to develop a framework for human autonomy teaming (HAT) in aviation, a study was conducted to evaluate proposed tenets of HAT. Participants performed a flight-following task at a ground station both with and without HAT features enabled. Overall, participants preferred the ground station with HAT features enabled over the station without the HAT features. Participants reported that the HAT displays and automation were preferred for keeping up with operationally important issues. Additionally, participants reported that the HAT displays and automation provided enough situation awareness to complete the task, reduced the necessary workload and were efficient. Overall, there was general agreement that HAT features supported teaming with the automation. These results will be used to refine and expand our proposed framework for human-autonomy teaming.

The objective of this study was to recognize the autonomy and vulnerability of nurses in the implementation of the Sistema da Assistência de Enfermagem (SAE) Nursing Care System through an integrative literature review, using content analysis. A survey was conducted, and 40 articles published between 1998 and 2008 were selected based on their relevance. Results showed two main categories of meaning: Benefits associated to the SAE practice (to patients, to the profession and to the institution) and Determinants for the Implementation of SAE (nurse's competence, training and education, record-instruments, infrastructure and collective sharing-construction). From the integration of the two categories, the highlights were the autonomy in acting with freedom and responsibility, science-based decision-making, and being valued for their social work, as well as the vulnerability expressed by interpersonal relationships, the wear generated by professional stress and the risk inherent to the service.

Cultural competency, autonomy, and spiritual conflicts related to Reiki/CAM therapies: Should patients be informed?

PubMed Central

Arvonio, Maria Marra

2014-01-01

The use of complementary and alternative medicines (CAM) such as Reiki is on the rise in healthcare centers. Reiki is associated with a spirituality that conflicts with some belief systems. Catholic healthcare facilities are restricted from offering this therapy because it conflicts with the teachings of the Catholic Church. However, hospitals are offering it without disclosing the spiritual aspects of it to patients. This article will address the ethical concerns and possible legal implications associated with the present process of offering Reiki. It will address these concerns based on the Joint Commission's Standard of Cultural Competency and the ethical principles of autonomy and informed consent. A proposal will also be introduced identifying specific information which Reiki/CAM practitioners should offer to their patients out of respect of their autonomy as well as their cultural, spiritual, and religious beliefs.

Patient-Perceived Autonomy and Long-Acting Reversible Contraceptive Use: A Qualitative Assessment in a Midwestern, University Community.

2018-01-01

Long-acting reversible contraceptives (LARCs) are the most effective contraceptives and are first-line recommendations for most women. However, young women use these methods at relatively low rates. Given concern with contraceptive coercion, an underexamined factor contributing to LARC attitudes is women's perceived reproductive and bodily autonomy in regard to LARC. We conducted focus group discussions and interviews regarding LARC perceptions and knowledge with 50 women between the ages of 18 and 29. We used a modified grounded theory approach to analyze young women's impressions of autonomy in relation to contraceptives more generally and LARC more specifically, both among ever-users and never-users. Four themes emerged regarding women's perceived autonomy with LARC. Control over pregnancy, active participation versus external agent, control over bleeding patterns, and autonomy in the provider/patient relationship. Within most themes, women made both positive and negative associations between perceived autonomy and LARC. The provider/patient relationship was a modifier of other themes, in that cooperative relationships may overshadow other perceived reductions in autonomy, and more unbalanced relationships may heighten perceived reductions in autonomy. Ever-users were more likely to report increased autonomy with LARC use, whereas never-users were more likely to express concerns about loss of autonomy with LARC. This study suggests that perceived autonomy may influence women's perceptions of LARC as well as their uptake of these contraceptive methods, with several factors both positively and negatively related to women's perceived autonomy. We encourage the integration of these findings into patient-centered counseling as well as educational materials for LARC.

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.

We tested a developmental cascade model of autonomy and relatedness in the progression from parent to friend to romantic relationships across ages 13, 18, and 21. Participants included 184 adolescents (53% female, 58% Caucasian, 29% African American) recruited from a public middle school in Virginia. Parental psychological control at age 13 undermined the development of autonomy and relatedness, predicting relative decreases in autonomy and relatedness with friends between ages 13 and 18 and lower levels of autonomy and relatedness with partners at age 18. These cascade effects extended into adult friendships and romantic relationships, with autonomy and relatedness with romantic partners at age 18 being a strong predictor of autonomy and relatedness with both friends and partners at age 21.

The purpose of the present study, grounded in self-determination theory, was to explore the relationship between Paralympic athletes' perceptions of autonomy-supportive coach behavior basic psychological needs, and intrinsic motivation to know, accomplish, and experience stimulation. One hundred thirteen Canadian Paralympic athletes completed an online survey, consisting of measures of coach autonomy support; of perceptions of autonomy, competence, and relatedness; and of intrinsic motivation. Perceived coach autonomy support was a predictor of athletes' perceptions of autonomy and relatedness. Perceived competence was a significant predictor of all three forms of intrinsic motivation, while perceived autonomy was a significant predictor of intrinsic motivation to accomplish and experience stimulation. The results highlight the important relationship between coach behavior and athlete motivation in disability sport.

To examine the relation of behavioral autonomy to psychological, behavioral, and physical health among emerging adults with and without type 1 diabetes. High school seniors with (n = 118) and without type 1 diabetes (n = 122) completed online questionnaires for three consecutive years. Behavioral autonomy, psychological health, risk behaviors, and diabetes outcomes were assessed. Regression analyses were conducted to predict Time 2 and 3 outcomes, controlling for Time 1 outcomes. There were no group differences in behavioral autonomy. Behavioral autonomy predicted better psychological health but only for emerging adults without diabetes. Behavioral autonomy was related to increased risk behavior for both groups. Behavioral autonomy was unrelated to self-care but predicted better glycemic control for females. Behavioral autonomy may be beneficial for psychological health, but is related to increased risk behavior. The implications of behavioral autonomy for emerging adults with type 1 diabetes require careful consideration. © The Author 2014.

Wireless charging is the key technology to realize real autonomy of mobile robots. As the core part of wireless power transfer system, coupling mechanism including coupling coils and compensation topology is analyzed and optimized through simulations, to achieve stable and practical wireless charging suitable for ordinary robots. Multi-layer coil structure, especially double-layer coil is explored and selected to greatly enhance coupling performance, while shape of ferrite shielding goes through distributed optimization to guarantee coil fault tolerance and cost effectiveness. On the basis of optimized coils, primary compensation topology is analyzed to adopt composite LCL compensation, to stabilize operations of the primary side under variations of mutual inductance. Experimental results show the optimized system does make sense for wireless charging application for robots based on magnetic resonance coupling, to realize long-term autonomy of robots.

The development and implementation of the Automated Space System Experimental Testbed (ASSET) space operations and control network, is reported on. This network will serve as a command and control architecture for spacecraft operations and will offer a real testbed for the application and validation of advanced autonomous spacecraft operations strategies. The proposed network will initially consist of globally distributed amateur radio ground stations at locations throughout North America and Europe. These stations will be linked via Internet to various control centers. The Stanford (CA) control center will be capable of human and computer based decision making for the coordination of user experiments, resource scheduling and fault management. The project's system architecture is described together with its proposed use as a command and control system, its value as a testbed for spacecraft autonomy research, and its current implementation.

Parent-adolescent dyads: association of parental autonomy support and parent-adolescent shared diabetes care responsibility.

Hanna, K M; Dashiff, C J; Stump, T E; Weaver, M T

2013-09-01

Parent-adolescent shared responsibility for diabetes care is advocated by experts to achieve beneficial diabetes and psychosocial outcomes for adolescents with type 1 diabetes. Parental autonomy support may be a way to facilitate this sharing. In this dyadic study, we examined parental diabetes-specific autonomy support experienced by adolescents with type 1 diabetes and their parents (n = 89 dyads), and its association with their experience of shared diabetes care responsibility. Path analysis was used to test an Actor-Partner Interdependence Model for parental autonomy support effects on shared responsibility. This was a secondary analysis of data from 89 parent-early/mid-adolescent dyads. Actor effects were identified. Parents' and adolescents' perceptions of parental autonomy support were associated with their respective reports of shared diabetes care responsibility. One partner effect was identified. Adolescents' reports of parental autonomy support were associated with parents' reports of shared responsibility. Parents and adolescents held similar views of autonomy support but discrepant views of shared responsibility. Older adolescents perceived less parental autonomy support. Increasing parental autonomy support may facilitate parent-adolescent sharing of diabetes care responsibility. Adolescent and parent perceptions influence each other and need to be considered when working with them to strengthen parental autonomy support. © 2012 John Wiley & Sons Ltd.

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

PubMed

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.

Assessment of Parent Orientation towards Autonomy vs. Control in Promoting Children's Healthy Eating and Exercise.

PubMed

Chiang, Evelyn S; Padilla, Miguel A

2012-07-01

Self-determination theory has been widely applied to understanding individuals' health-related behaviors such as eating healthy foods and exercising. Different reasons for engagement are associated with varying levels of personal agency or autonomy. Authority figures in the environment can be supportive of autonomy or, in contrast, controlling. Although researchers have assessed individuals' perceptions of the autonomy-support in their environments, studies have not directly examined the authority figures' orientations to autonomy with respect to health contexts. A new scale, Parent Orientations to Health, was created to investigate parent orientation to autonomy and control with respect to healthy eating and exercise in children. One hundred and forty-three parents of elementary school-aged children responded to the scale. Scale validation and reliability results indicate that the scale successfully assessed parent orientation towards autonomy for children in health contexts. Furthermore, parent autonomy orientation varied according to child weight status and the healthiness of the child's diet. Parent orientation towards autonomy can be evaluated through the use of the Parent Orientations to Health scale. In addition, parent autonomy orientation is associated with both the healthiness of the child's diet (as perceived by the parent) and the child's body mass index. © 2012 The Authors.

Conflicting contraceptive norms for men: equal responsibility versus women's bodily autonomy.

PubMed

James-Hawkins, Laurie; Dalessandro, Cristen; Sennott, Christie

2018-05-15

Most research investigating how men and women in heterosexual relationships negotiate contraceptive use focuses on the women's point of view. Using a sample of 44 interviews with men attending a western US university, this study examines norms governing men's participation in contraceptive use and pregnancy prevention and their responses to those norms. The paper demonstrates how competing norms around sexual health decision-making and women's bodily autonomy contribute to unintended outcomes that undermine young people's quest for egalitarian sexual relationships. While men largely agree that responsibility for sexual health decision-making should be shared with women, they also believe that women should have power over their own bodies and sexual health. However, the coexistence of these two competing norms - which call for both equal responsibility in decision-making and women's bodily autonomy - results in a disconnect between men saying that sexual health decision-making should be equal, but not always participating equally. Thus, men largely give contraceptive decision-making power over to women, putting the burden of pregnancy prevention onto women and letting men off the hook. It is concluded that men's negotiation of these competing norms reinforces unequal power and inequality in sexual relationships.

Odborg, M H; Eriksen, T R; Petersson, B H

1995-09-04

A questionnaire was given to 254 medical students matriculated in 1992/93 concerning their motivation for wanting to become a doctor, attitudes towards which qualities a doctor should have and their potential choice of medical specialty. The analysis focuses on whether answers are relation-orientated (i.e. directed towards relations to others) or autonomy-orientated (i.e. directed towards rationality and independence). The results show that motivations for becoming a doctor are both relation- and autonomy-orientated. Most students expect the doctor to both be able to relate to the patient and be professionally competent. No gender differences could be demonstrated concerning motivations for becoming a doctor or which qualities a good doctor should possess. Significant gender differences were displayed concerning choice of specialty, most women aiming towards relation-orientated specialties and most men aiming towards autonomy-orientated specialties. It is concluded that the growing proportion of women doctors could change the medical profession towards becoming more patient- and relation-orientated, however their choice of relation-orientated and lower prestige specialties could result in less overall influence than one might otherwise expect.

This article explores a potential scenario for the further development of space infrastructure resources and operations management. It is a scenario that transitions from the current ground-based system to an architecture that is predominantly space-based by exploiting key mission systems in an operational support role. If this view is accurate, an examination of the range of potential infrastructure elements and how they might interact in a maximally productive space-based operations complex is needed, innovative technologies beyond the current Shuttle and Space Station legacy need to be identified, and research programs pursued. Development of technologies within the areas of telerobotics, machine autonomy, human autonomy, in-space manufacturing and construction, propulsion and energy is discussed.

This paper describes the integration of the Remote Agent (RA), a spacecraft autonomy system which is scheduled to control the Deep Space 1 spacecraft during a flight experiment in 1999. The RA is a reusable, model-based autonomy system that is quite different from software typically used to control an aerospace system. We describe the integration challenges we faced, how we addressed them, and the lessons learned. We focus on those aspects of integrating the RA that were either easier or more difficult than integrating a more traditional large software application because the RA is a model-based autonomous system. A number of characteristics of the RA made integration process easier. One example is the model-based nature of RA. Since the RA is model-based, most of its behavior is not hard coded into procedural program code. Instead, engineers specify high level models of the spacecraft's components from which the Remote Agent automatically derives correct system-wide behavior on the fly. This high level, modular, and declarative software description allowed some interfaces between RA components and between RA and the flight software to be automatically generated and tested for completeness against the Remote Agent's models. In addition, the Remote Agent's model-based diagnosis system automatically diagnoses when the RA models are not consistent with the behavior of the spacecraft. In flight, this feature is used to diagnose failures in the spacecraft hardware. During integration, it proved valuable in finding problems in the spacecraft simulator or flight software. In addition, when modifications are made to the spacecraft hardware or flight software, the RA models are easily changed because they only capture a description of the spacecraft. one does not have to maintain procedural code that implements the correct behavior for every expected situation. On the other hand, several features of the RA made it more difficult to integrate than typical flight software. For example, the definition of correct behavior is more difficult to specify for a system that is expected to reason about and flexibly react to its environment than for a traditional flight software system. Consequently, whenever a change is made to the RA it is more time consuming to determine if the resulting behavior is correct. We conclude the paper with a discussion of future work on the Remote Agent as well as recommendations to ease integration of similar autonomy projects.

Background: One of the important factors in the prediction of family planning outcome is paying attention to women's role in decision making concerning fertility and household affairs. With the improvement of women's status and autonomy, their control over fertility is expected to increase. The present study aimed to investigate the association between women's autonomy and family planning outcome of the couples residing in Isfahan. Materials and Methods: This is cross-sectional study. Two hundred and seventy women of childbearing age, eligible for family planning and residing in Isfahan, were selected through random cluster sampling and they filled a researcher-made questionnaire. Women's autonomy was measured with the questions on their decision-making autonomy concerning household affairs and physical mobility autonomy. The association between women's autonomy and family planning outcome was analyzed through statistical methods. Results: The results showed that the mean of women's decision-making, physical mobility, and general autonomy was 50. Women's autonomy had a direct significant association with the type of contraception method (P = 0.01) and the length of usage of their present contraception method (P = 0.04) as well as where they received family planning services (P = 0.02). Conclusions: Analysis of data revealed women with higher autonomy used a more efficient contraception method and continued their contraception method for a longer time, which leads to improvement of couples’ family planning outcome. Therefore, family planning services should be planned and provided with women's autonomy under consideration. PMID:25400671

This study used a longitudinal, multi-method design to examine whether teens’ perceptions of maternal psychological control predicted lower levels of adolescent autonomy displayed with their mothers and peers over time. Significant predictions from teens’ perceptions of maternal psychological control to teens’ displays of autonomy in maternal and peer relationships were found at age 16 after accounting for adolescent displays of autonomy with mothers and peers at age 13, indicating relative changes in teens’ autonomy displayed with their mother and a close peer over time. Results suggest that the ability to assert one’s autonomy in mid-adolescence may be influenced by maternal behavior early in adolescence, highlighting the importance of parents minimizing psychological control to facilitate autonomy development for teens.

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.

2016-01-01

Despite various efforts for enhancing women’s autonomy in developing countries, many women are deprived of their capacity in decision-making on their household affairs as well as social issues. This paper aimed to examine women’s autonomy and its associated factors in the Kapilvastu district of Nepal. We measured women’s autonomy using a recently developed women’s autonomy measurement scale from June to October 2014. Descriptive statistics, chi-square test and logistic multivariate modeling technique were applied for assessing the association of demographic and socio-economic characteristics of women and their autonomy. Mean score for women’s autonomy was 23.34± 8.06 out of the possible maximum 48. It was found to be positively associated with higher age difference at marriage, advantaged caste/ethnicity, better employment for the husband, couple’s education more than 10 years schooling, and higher economic status of the household. We found strong direct effect of women’s education (OR = 8.14, CI = 3.77–17.57), husband’s education (OR = 2.63, CI = 1.69–4.10) and economic status of household (OR = 1.42, CI = 1.01–2.03) on women’s autonomy. When we adjusted women’s education for husband’s education, the odds ratio decreased by around 22% {from (OR = 8.14, CI = 3.77–17.57) to (OR = 6.32, CI = 2.77–14.46)} and was a mediator effect. The economic status of household also had mediator effect on women’s autonomy through their education. Education status of women is a key predictor of women’s autonomy in Kapilvastu district. Husband’s education and economic status of the household are other important predictors of women’s autonomy which have a mediator effect on women’s autonomy. Improving educational status and economic conditions of both women and their husbands may be the best solution to promote women’s autonomy. PMID:26799217

Shared decision-making and patient autonomy.

PubMed

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.

Authenticity and autonomy in deep-brain stimulation.

PubMed

Wardrope, Alistair

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.

[Autonomy for financial management in public and private healthcare facilities in Brazil].

PubMed

Santos, Maria Angelica Borges dos; Madeira, Fátima Carvalho; Passos, Sonia Regina Lambert; Bakr, Felipe; Oliveira, Klivia Brayner de; Andreazzi, Marco Antonio Ratzsch de

2014-01-01

Autonomy in financial management is an advantage in public administration. A 2009 National Healthcare Facility Survey showed that 3.9% of Brazil's 52,055 public healthcare facilities had some degree of financial autonomy. Such autonomy was more common in inpatient facilities (17.8%), those managed by State governments (26.3%), and in Southern Brazil (6.6%). Autonomy was mainly partial (for resources in specific areas, relating to small outlays, consumables and capital goods, and outsourced services or personnel). 74.3% of 2,264 public facilities with any financial autonomy were under direct government administration. Financial autonomy in public healthcare facilities appears to be linked to local political decisions and not necessarily to the facility's specific legal and administrative status. However, legal status displays distinct scopes of autonomy - those under direct government administration tend to be less autonomous, and those under private businesses more autonomous; 85.8% of the 45,394 private healthcare facilities reported that they were financially autonomous.

Women's Autonomy and Attitudes toward Condom Use: A Multicountry Analysis.

Autonomy gives women the ability to negotiate safe sex and make decisions on their health. This study explores the gender stratification framework to understand the intertwined nature of HIV and women's autonomy using the nationally representative Demographic Health Survey. It examines women's autonomy and attitudes toward condom use for prevention of HIV/AIDS in four culturally diverse countries. Findings from the logistic regression indicate that labor force participation, individual autonomy, and decision making significantly increased the odds of always using a condom during sex in all countries. Promoting prevention policies highlighting women's autonomy may contribute in reducing the spread of HIV infection.

Autonomy in military aircraft

NASA Astrophysics Data System (ADS)

Henderson, D. W.

Military users are becoming increasingly dependent on satellites for vital services related to communication, surveillance information, navigation, and meteorological data. The current military spacecraft, however, need the services of a ground support network which is vulnerable in connection with a variety of threats. It has, therefore, been proposed to decrease the dependence of the satellites on the ground segment by improving satellite autonomy, and the Satellite Autonomy Program at the recently created Air Force Space Technology Center is developing the Autonomous Redundancy and Maintenance Management Subsystem (ARMMS) for a near term generic autonomy solution. Attention is given to the implementation of autonomy and technological requirements for ensuring autonomy.

Obesity prevention advocacy in Australia: an analysis of policy impact on autonomy.

PubMed

Haynes, Emily; Hughes, Roger; Reidlinger, Dianne P

2017-06-01

To explore obesity policy options recommended by stakeholders and identify their impact on individual autotomy. Qualitative and quantitative methods were used. A content analysis of submissions to the Australian Government's Inquiry into Obesity was conducted. Each recommendation was categorised by its impact on autonomy, according to existing frameworks. Chi-square test for independence was used to explore the association between autonomy and stakeholder support defined as frequency of recommendation. The extent of support for a policy option was significantly associated with impact on autonomy (p<0.001). Options that reduce autonomy were least frequently recommended in every setting; but more likely in schools (27%) than other settings (<1%). Recommendations to provide incentives (9%) were more common than disincentives (2%) or restrictions (3%), and those that enhance autonomy were most widely recommended (46%). Stakeholders advocated policy options that enhance individual autonomy to a greater extent than those that diminish autonomy. Implications for public health: Targeting obesity policy options that enhance rather than diminish autonomy may be more politically acceptable across most settings, with the exception of schools where more restrictive policy options are appropriate. Re-framing options accordingly may improve leadership by government in obesity policy. © 2017 The Authors.

Autonomy-based arguments against physician-assisted suicide and euthanasia: a critique.

PubMed

Sjöstrand, Manne; Helgesson, Gert; Eriksson, Stefan; Juth, Niklas

2013-05-01

Respect for autonomy is typically considered a key reason for allowing physician assisted suicide and euthanasia. However, several recent papers have claimed this to be grounded in a misconception of the normative relevance of autonomy. It has been argued that autonomy is properly conceived of as a value, and that this makes assisted suicide as well as euthanasia wrong, since they destroy the autonomy of the patient. This paper evaluates this line of reasoning by investigating the conception of valuable autonomy. Starting off from the current debate in end-of-life care, two different interpretations of how autonomy is valuable is discussed. According to one interpretation, autonomy is a personal prudential value, which may provide a reason why euthanasia and assisted suicide might be against a patient's best interests. According to a second interpretation, inspired by Kantian ethics, being autonomous is unconditionally valuable, which may imply a duty to preserve autonomy. We argue that both lines of reasoning have limitations when it comes to situations relevant for end-of life care. It is concluded that neither way of reasoning can be used to show that assisted suicide or euthanasia always is impermissible.

Desire for autonomy in health care decisions: a general population survey.

To examine factors associated with desire for autonomy in health care decisions in the general population. Mailed survey of 2348 residents of Geneva, Switzerland. Participants answered questions on a scale measuring their desire for autonomy in health care decisions. The scale was scored between 0 (lowest desire for autonomy) and 100 (highest desire for autonomy). On average the respondents favoured shared or active involvement in medical decisions (mean score 62.0, SD 20.9), but attitudes varied considerably. In the multivariate model, factors associated with a higher desire for autonomy included female gender, younger age, higher education, living alone, reporting an excellent global health and - a new observation compared to previous studies - having made several medical decisions in the past 6 months. The attitudes of the general public appear to be consistent with the model of shared decision making. However, people vary considerably in their desire for autonomy. An explicit assessment of each individual's desire for autonomy may improve the decision-making process. Such an assessment should be repeated regularly, as familiarity with medical decisions may increase the desire for autonomy. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

2017-01-01

With the development of satellite mobile communications, large antennas are now widely used. The precise pointing of the antenna’s optical axis is essential for many space missions. This paper addresses the challenging problem of high-precision autonomous pointing control of a large satellite antenna. The pointing dynamics are firstly proposed. The proportional–derivative feedback and structural filter to perform pointing maneuvers and suppress antenna vibrations are then presented. An adaptive controller to estimate actual system frequencies in the presence of modal parameters uncertainty is proposed. In order to reduce periodic errors, the modified controllers, which include the proposed adaptive controller and an active disturbance rejection filter, are then developed. The system stability and robustness are analyzed and discussed in the frequency domain. Numerical results are finally provided, and the results have demonstrated that the proposed controllers have good autonomy and robustness. PMID:28287450

Security-Enhanced Autonomous Network Management

Zeng, Hui

2015-01-01

Ensuring reliable communication in next-generation space networks requires a novel network management system to support greater levels of autonomy and greater awareness of the environment and assets. Intelligent Automation, Inc., has developed a security-enhanced autonomous network management (SEANM) approach for space networks through cross-layer negotiation and network monitoring, analysis, and adaptation. The underlying technology is bundle-based delay/disruption-tolerant networking (DTN). The SEANM scheme allows a system to adaptively reconfigure its network elements based on awareness of network conditions, policies, and mission requirements. Although SEANM is generically applicable to any radio network, for validation purposes it has been prototyped and evaluated on two specific networks: a commercial off-the-shelf hardware test-bed using Institute of Electrical Engineers (IEEE) 802.11 Wi-Fi devices and a military hardware test-bed using AN/PRC-154 Rifleman Radio platforms. Testing has demonstrated that SEANM provides autonomous network management resulting in reliable communications in delay/disruptive-prone environments.

Autonomous Control of Nuclear Power Plants

A nuclear reactor is a complex system that requires highly sophisticated controllers to ensure that desired performance and safety can be achieved and maintained during its operations. Higher-demanding operational requirements such as reliability, lower environmental impacts, and improved performance under adverse conditions in nuclear power plants, coupled with the complexity and uncertainty of the models, necessitate the use of an increased level of autonomy in the control methods. In the opinion of many researchers, the tasks involved during nuclear reactor design and operation (e.g., design optimization, transient diagnosis, and core reload optimization) involve important human cognition and decisions that maymore » be more easily achieved with intelligent methods such as expert systems, fuzzy logic, neural networks, and genetic algorithms. Many experts in the field of control systems share the idea that a higher degree of autonomy in control of complex systems such as nuclear plants is more easily achievable through the integration of conventional control systems and the intelligent components. Researchers have investigated the feasibility of the integration of fuzzy logic, neural networks, genetic algorithms, and expert systems with the conventional control methods to achieve higher degrees of autonomy in different aspects of reactor operations such as reactor startup, shutdown in emergency situations, fault detection and diagnosis, nuclear reactor alarm processing and diagnosis, and reactor load-following operations, to name a few. With the advancement of new technologies and computing power, it is feasible to automate most of the nuclear reactor control and operation, which will result in increased safety and economical benefits. This study surveys current status, practices, and recent advances made towards developing autonomous control systems for nuclear reactors.« less

Iliopoulou, Katerina K; While, Alison E

2010-11-01

This paper is a report of a study conducted to describe Greek critical care nurses' views on professional autonomy and its relationship with job satisfaction and other work-related variables. Professional autonomy is generally considered a highly desirable nursing attribute and a major factor in nurse job satisfaction. In the critical care environment, a high level of accountability, responsibility and autonomy are required to optimize outcomes of critically unstable patients. A questionnaire survey was conducted with a convenience sample of Greek critical care nurses (n = 431; response rate 70%) in 2007. Data were collected on professional autonomy, job satisfaction, role conflict and role ambiguity. Overall, nurses reported acting moderately autonomously. Younger nurses reported statistically significant lower levels of autonomy. Higher levels of autonomy were reported by female nurses. Multiple logistic regression revealed that appointment level, type of critical care unit and registration with a professional organization were independently associated with autonomy. A positive moderate association was found between reported autonomy, job satisfaction, role conflict and role ambiguity, but there was no relationship between job satisfaction and reported role conflict and role ambiguity. Further education, role enhancement and support are required for nurses working in critical care in Greece if they are to achieve the maximum potential of their professional role. Failure to address the perceptions of professional autonomy may have an impact on staff retention, because of job dissatisfaction. © 2010 Blackwell Publishing Ltd.

Autonomous control systems: applications to remote sensing and image processing

NASA Astrophysics Data System (ADS)

Jamshidi, Mohammad

2001-11-01

One of the main challenges of any control (or image processing) paradigm is being able to handle complex systems under unforeseen uncertainties. A system may be called complex here if its dimension (order) is too high and its model (if available) is nonlinear, interconnected, and information on the system is uncertain such that classical techniques cannot easily handle the problem. Examples of complex systems are power networks, space robotic colonies, national air traffic control system, and integrated manufacturing plant, the Hubble Telescope, the International Space Station, etc. Soft computing, a consortia of methodologies such as fuzzy logic, neuro-computing, genetic algorithms and genetic programming, has proven to be powerful tools for adding autonomy and semi-autonomy to many complex systems. For such systems the size of soft computing control architecture will be nearly infinite. In this paper new paradigms using soft computing approaches are utilized to design autonomous controllers and image enhancers for a number of application areas. These applications are satellite array formations for synthetic aperture radar interferometry (InSAR) and enhancement of analog and digital images.

The cascading development of autonomy and relatedness from adolescence to adulthood.

2015-01-01

A developmental cascade model of autonomy and relatedness in the progression from parent to friend to romantic relationships across ages 13, 18, and 21 was examined among 184 adolescents (53% female, 58% Caucasian, 29% African American) recruited from a public middle school in Virginia. Parental psychological control at age 13 undermined the development of autonomy and relatedness, predicting relative decreases in autonomy and relatedness with friends between ages 13 and 18 and lower levels of autonomy and relatedness with partners at age 18. These cascade effects extended into adult friendships and romantic relationships, with autonomy and relatedness with romantic partners at age 18 being a strong predictor of autonomy and relatedness with both friends and partners at age 21. © 2014 The Authors.

Students' motivational processes and their relationship to teacher ratings in school physical education: a self-determination theory approach.

PubMed

Standage, Martyn; Duda, Joan L; Ntoumanis, Nikos

2006-03-01

In the present study, we used a model of motivation grounded in self-determination theory (Deci & Ryan, 1985, 1991; Ryan & Deci, 2000a, 2000b, 2002) to examine the relationship between physical education (PE) students' motivational processes and ratings of their effort and persistence as provided by their PE teacher. Data were obtained from 394 British secondary school students (204 boys, 189 girls, 1 gender not specified; M age = 11.97 years; SD = .89; range = 11-14 years) who responded to a multisection inventory (tapping autonomy-support, autonomy, competence, relatedness, and self-determined motivation). The students' respective PE teachers subsequently provided ratings reflecting the effort and persistence each student exhibited in their PE classes. The hypothesized relationships among the study variables were examined via structural equation modeling analysis using latent factors. Results of maximum likelihood analysis using the bootstrapping method revealed the proposed model demonstrated a good fit to the data, chi-squared (292) = 632.68, p < .001; comparative fit index = .95; incremental fit index = .95, standardized root mean square residual = .077; root mean square error of approximation (RMSEA) = .054 (90% confidence interval of RMSEA = .049 -.060). Specifically, the model showed that students who perceived an autonomy supportive environment experienced greater levels of autonomy, competence, and relatedness and had higher scores on an index of self-determination. Student-reported levels of self-determined motivation positively predicted teacher ratings of effort and persistence in PE. The findings are discussed with regard to enhancing student motivation in PE settings.

Autonomy and dependence--experiences of home abortion, contraception and prevention.

Few studies have explored experiences and needs in relation to an induced medical abortion with the final treatment at home. To explore women's and men's experiences and needs related to care in the context of a home abortion as well as to elicit their views on contraception and prevention of unwanted pregnancies. Qualitative interviews were carried out with 24 women and 13 men who had experienced a home abortion; they took place in Sweden during 2009/10. Two overarching themes were identified: Autonomy--the decision to undergo an abortion and the choice of method were well considered by the woman, supported by the partner. The home environment increased their privacy and control, which helped them freely express and share their emotions. They were motivated to avoid a subsequent abortion and considered it an individual responsibility; however, contraceptive follow-up visits were rare. Dependence--a desire to be treated with empathy and respect by care providers and to receive adequate information. In the prevention of unwanted pregnancies, financial resources, improved communication/education and subsidized contraceptives were considered important. Home abortion increases autonomy, and women and partners demonstrate self-care ability. This autonomy, however, is related to dependence: a desire to be treated with empathy and respect on equal terms and to receive adequate information tailored to their self-care needs. Routines in abortion care should be continuously evaluated to ensure care satisfaction, safety and security as well as contraceptive adherence. © 2012 The Authors.

Enabling Advanced Automation in Spacecraft Operations with the Spacecraft Emergency Response System

NASA Technical Reports Server (NTRS)

Breed, Julie; Fox, Jeffrey A.; Powers, Edward I. (Technical Monitor)

2001-01-01

True autonomy is the Holy Grail of spacecraft mission operations. The goal of launching a satellite and letting it manage itself throughout its useful life is a worthy one. With true autonomy, the cost of mission operations would be reduced to a negligible amount. Under full autonomy, any problems (no matter the severity or type) that may arise with the spacecraft would be handled without any human intervention via some combination of smart sensors, on-board intelligence, and/or smart automated ground system. Until the day that complete autonomy is practical and affordable to deploy, incremental steps of deploying ever-increasing levels of automation (computerization of once manual tasks) on the ground and on the spacecraft are gradually decreasing the cost of mission operations. For example, NASA's Goddard Space Flight Center (NASA-GSFC) has been flying spacecraft with low cost operations for several years. NASA-GSFC's SMEX (Small Explorer) and MIDEX (Middle Explorer) missions have effectively deployed significant amounts of automation to enable the missions to fly predominately in 'light-out' mode. Under light-out operations the ground system is run without human intervention. Various tools perform many of the tasks previously performed by the human operators. One of the major issues in reducing human staff in favor of automation is the perceived increased in risk of losing data, or even losing a spacecraft, because of anomalous conditions that may occur when there is no one in the control center. When things go wrong, missions deploying advanced automation need to be sure that anomalous conditions are detected and that key personal are notified in a timely manner so that on-call team members can react to those conditions. To ensure the health and safety of its lights-out missions, NASA-GSFC's Advanced Automation and Autonomy branch (Code 588) developed the Spacecraft Emergency Response System (SERS). The SERS is a Web-based collaborative environment that enables secure distributed fault and resource management. The SERS incorporates the use of intelligent agents, threaded discussions, workflow, database connectivity, and links to a variety of communications devices (e.g., two-way paging, PDA's, and Internet phones) via commercial gateways. When the SERS detects a problem, it notifies on-call team members, who then can remotely take any necessary actions to resolve the anomalies.The SERS goes well beyond a simple '911' system that sends out an error code to everyone with a pager. Instead, SERS' software agents send detailed data (i.e., notifications) to the most appropriate team members based on the type and severity of the anomaly and the skills of the on-call team members. The SERS also allows the team members to respond to the notifications from their wireless devices. This unique capability ensures rapid response since the team members no longer have to go to a PC or the control center for every anomalous event. Most importantly, the SERS enables safe experimentation with various techniques for increasing levels of automation, leading to robust autonomy. For the MIDEX missions at NASA GSFC, the SERS is used to provide 'human-in-the-loop' automation. During lights-out operations, as greater control is given to the MIDEX automated systems, the SERS can be configured to page remote personnel and keep them informed regarding actions taking place in the control center. Remote off-duty operators can even be given the option of enabling or inhibiting a specific automated response in near real time via their two-way pagers. The SERS facilitates insertion of new technology to increase automation, while maintaining the safety and security of mission resources. This paper will focus on SERS' overall functionality and how SERS has been designed to handle the monitoring and emergency response for missions with varying levels of automation. The paper will also convey some of the key lessons learned from SERS' deployment across of variety of missions, highlighting this incremental approach to achieving 'robust autonomy'.
