HSX is a quasi-helically symmetric (QHS) stellarator currently under construction at the Torsatron-Stellarator Laboratory of the University of Wisconsin-Madison. This device is unique in its magnetic design in that the magnetic field spectrum possesses only a single dominant (helical) component. This design avoids the large direct orbit losses and the low-collisionality neoclassical losses associated with conventional stellarators. The restoration of symmetry to the confining magnetic field makes the neoclassical confinement in this device analogous to an axisymmetric q=1/3 tokamak. The HSX device has been designed with a clear set of primary physics goals: demonstrate the feasibility of construction of a QHS device, examine single particle confinement of injected ions with regard to magnetic field symmetry breaking, compare density and temperature profiles in this helically symmetric system to those for axisymmetric tokamaks and conventional stellarators, examine electric fields and plasma rotation with edge biasing in relation to L-H transitions in symmetric versus non-symmetric stellarator systems, investigate QHS effects on 1/v regime electron confinement, and examine how greatly-reduced neoclassical electron thermal conductivity compares to the experimental χ e profile. 3 refs., 4 figs., 1 tab

Improved OSC Amtec generator design to meet goals of JPL's candidate Europa Orbiter mission

International Nuclear Information System (INIS)

Schock, A.; Noravian, H.; Or, C.; Kumar, V.

1998-01-01

The preceding paper (Paper IECEC.98.244) described OSC's initial designs of AMTEC (Alkali Metal Thermal-to-Electrical Conversion) power systems, consisting of one or two generators, each with 2, 3, or 4 General Purpose Heat Source (GPHS) modules and with 16 refractory AMTEC cells containing 5 Beta Alumina Solid Electrolyte (BASE) tubes; and presented the effect of heat input and voltage output on the generator's BOM evaporator and clad temperatures and on its EOM system efficiency and power output. Comparison of the computed results with JPL's goals for the Europa Orbiter mission showed that all of the initial 16-cell design options yielded either excessive evaporator and clad temperatures or insufficient EOM power to satisfy the JPL-specified mission goals. The present paper describes modified OSC generator designs with different numbers of AMTEC cells, cell diameters, cell lengths, cell materials, BASE tube lengths, and number of tubes per cell. These efforts succeeded in identifying generator designs with only half the number of AMTEC cells which -- for the same assumptions -- can produce EOM power outputs substantially in excess of JPL's goals for NASA's Europa Orbiter mission while operating well below the prescribed BOM limits on evaporator and clad temperature; and revealed that lowering the emissivity of the generator's housing to raise the cells' condenser temperatures can achieve substantial additional performance improvement. Finally, the paper culminates in programmatic recommendations

Development of quantitative goals for inherent safety feature design and licensing

Kastenberg, W.E.; Apostolakis, G.; Dhir, V.K.; Okrent, D.

1987-01-01

There is now considerable interest in the development of advanced fast reactors whose major focus is inherent safety. The achievement of inherent safety can be viewed from several aspects. In the Integral Fast Reactor Concept the approach is to utilize the intrinsic characteristics of pool-type liquid metal fast breeder reactors (LMFBRs) and the properties of metal fuels to integrate a high degree of inherent safety into the design. The PRISM and SAFR concepts focus on other inherent safety features. The reactors discussed above represent a radical departure from existing LWR designs as well as previous LMFBR designs (e.g., CRBRP) which are based, for the most part, on the General Design Criteria found in 10CFR50 Appendix. In view of these parallel developments (advanced reactors exploiting inherent safety and the use of quantitative goals to augment licensing), there appears to be a need to perform research on the development of methods for designing, assessing, and licensing inherent safety features in advanced reactors. The objectives of such research are outlined

The impact of goal-oriented task design on neurofeedback learning for brain-computer interface control.

2018-02-01

Neurofeedback training teaches individuals to modulate brain activity by providing real-time feedback and can be used for brain-computer interface control. The present study aimed to optimize training by maximizing engagement through goal-oriented task design. Participants were shown either a visual display or a robot, where each was manipulated using motor imagery (MI)-related electroencephalography signals. Those with the robot were instructed to quickly navigate grid spaces, as the potential for goal-oriented design to strengthen learning was central to our investigation. Both groups were hypothesized to show increased magnitude of these signals across 10 sessions, with the greatest gains being seen in those navigating the robot due to increased engagement. Participants demonstrated the predicted increase in magnitude, with no differentiation between hemispheres. Participants navigating the robot showed stronger left-hand MI increases than those with the computer display. This is likely due to success being reliant on maintaining strong MI-related signals. While older participants showed stronger signals in early sessions, this trend later reversed, suggesting greater natural proficiency but reduced flexibility. These results demonstrate capacity for modulating neurofeedback using MI over a series of training sessions, using tasks of varied design. Importantly, the more goal-oriented robot control task resulted in greater improvements.

2018-08-01

To deliver client-centered care, physiotherapists need to identify the patients' individual treatment goals. However, practical tools for involving patients in goal setting are lacking. The purpose of this study was to improve the frequently used Patient-Specific Complaints instrument in Dutch physiotherapy, and to develop it into a feasible method to improve physiotherapy goal setting. An iterative user-centered design was conducted in co-creation with the physiotherapists and patients, in three phases. Their needs and preferences were identified by means of group meetings and questionnaires. The new method was tested in several field tests in physiotherapy practices. Four main objectives for improvement were formulated: clear instructions for the administration procedure, targeted use across the physiotherapy process, client-activating communication skills, and a client-centered attitude of the physiotherapist. A theoretical goal-setting framework and elements of shared decision making were integrated into the new-called, Patient-Specific Goal-setting method, together with a practical training course. The user-centered approach resulted in a goal-setting method that is fully integrated in the physiotherapy process. The new goal-setting method contributes to a more structured approach to goal setting and enables patient participation and goal-oriented physiotherapy. Before large-scale implementation, its feasibility in physiotherapy practice needs to be investigated. Implications for rehabilitation Involving patients and physiotherapists in the development and testing of a goal-setting method, increases the likelihood of its feasibility in practice. The integration of a goal-setting method into the physiotherapy process offers the opportunity to focus more fully on the patient's goals. Patients should be informed about the aim of every step of the goal-setting process in order to increase their awareness and involvement. Training physiotherapists to use a patient

Probabilistic safety assessment goals in Canada

International Nuclear Information System (INIS)

Snell, V.G.

1986-01-01

CANDU safety philosphy, both in design and in licensing, has always had a strong bias towards quantitative probabilistically-based goals derived from comparative safety. Formal probabilistic safety assessment began in Canada as a design tool. The influence of this carried over later on into the definition of the deterministic safety guidelines used in CANDU licensing. Design goals were further developed which extended the consequence/frequency spectrum of 'acceptable' events, from the two points defined by the deterministic single/dual failure analysis, to a line passing through lower and higher frequencies. Since these were design tools, a complete risk summation was not necessary, allowing a cutoff at low event frequencies while preserving the identification of the most significant safety-related events. These goals gave a logical framework for making decisions on implementing design changes proposed as a result of the Probabilistic Safety Analysis. Performing this analysis became a regulatory requirement, and the design goals remained the framework under which this was submitted. Recently, there have been initiatives to incorporate more detailed probabilistic safety goals into the regulatory process in Canada. These range from far-reaching safety optimization across society, to initiatives aimed at the nuclear industry only. The effectiveness of the latter is minor at very low and very high event frequencies; at medium frequencies, a justification against expenditures per life saved in other industries should be part of the goal setting

A Novel Double Cluster and Principal Component Analysis-Based Optimization Method for the Orbit Design of Earth Observation Satellites

Directory of Open Access Journals (Sweden)

Yunfeng Dong

2017-01-01

Full Text Available The weighted sum and genetic algorithm-based hybrid method (WSGA-based HM, which has been applied to multiobjective orbit optimizations, is negatively influenced by human factors through the artificial choice of the weight coefficients in weighted sum method and the slow convergence of GA. To address these two problems, a cluster and principal component analysis-based optimization method (CPC-based OM is proposed, in which many candidate orbits are gradually randomly generated until the optimal orbit is obtained using a data mining method, that is, cluster analysis based on principal components. Then, the second cluster analysis of the orbital elements is introduced into CPC-based OM to improve the convergence, developing a novel double cluster and principal component analysis-based optimization method (DCPC-based OM. In DCPC-based OM, the cluster analysis based on principal components has the advantage of reducing the human influences, and the cluster analysis based on six orbital elements can reduce the search space to effectively accelerate convergence. The test results from a multiobjective numerical benchmark function and the orbit design results of an Earth observation satellite show that DCPC-based OM converges more efficiently than WSGA-based HM. And DCPC-based OM, to some degree, reduces the influence of human factors presented in WSGA-based HM.

Conceptual Models Core to Good Design

Johnson, Jeff

2011-01-01

People make use of software applications in their activities, applying them as tools in carrying out tasks. That this use should be good for people--easy, effective, efficient, and enjoyable--is a principal goal of design. In this book, we present the notion of Conceptual Models, and argue that Conceptual Models are core to achieving good design. From years of helping companies create software applications, we have come to believe that building applications without Conceptual Models is just asking for designs that will be confusing and difficult to learn, remember, and use. We show how Concept

Funding policy based on hospital casemix has traditionally been considered to be only about promoting efficiency. Discussion Formula-based funding policy can be (and has been used to pursue a range of policy objectives, not only efficiency. These are termed 'adjunct' goals. Strategies to incorporate adjunct goals into funding design must, implicitly or explicitly, address key decision choices outlined in this paper. Summary Policy must be clear and explicit about the behaviour to be rewarded; incentives must be designed so that all facilities with an opportunity to improve have an opportunity to benefit; the reward structure is stable and meaningful; and the funder monitors performance and gaming.

Lee, Eunji; Gammon, Deede

2017-01-01

Care for patients with long term conditions is often characterized as fragmented and ineffective, and fails to engage the resources of patients and their families in the care process. Information and communication technology can potentially help bridge the gap between patients' lives and resources and services provided by professionals. However, there is little attention on how to identify and incorporate the patients' individual needs, values, preferences and care goals into the digitally driven care settings. We conducted a case study with healthcare professionals and patients participated applying a service design thinking approach. The participants could elaborate some personal goals of patients with long term condition which can potentially be incorporated in digitally driven care plans using examples from their own experiences.

Full Text Available Research Question (RQ: What kind of lifestyle do the principals and entrepreneurs lead? Does the lifestyle of principals and entrepreneurs influence burnout? Purpose: To find out, based on the results of a questionnaire, what kind of lifestyle both researched groups lead. Does lifestyle have an influence on the occurrence of the phenomenon of burnout. Method: We used the method of data collection by questionnaire. Acquired data were analyzed using SPSS, descriptive and inference statistics. Results: Results showed, that both groups lead a similar lifestyle and that lifestyle influences burnout with principals, as well as entrepreneurs. Organization: School principals and entrepreneurs are the heads of individual organizations or companies, the goal of which is success. To be successful in their work, they must adapt their lifestyle, which can be healthy or unhealthy. If their lifestyle is unhealthy, it can lead to burnout. Society: With results of the questionnaire we would like to answer the question about the lifestyle of both groups and its influence on the occurrence of burnout. Originality: The study of lifestyle and the occurrence of burnout in these two groups is the first study in this area. Limitations/Future Research: In continuation, research groups could be submitted to the research fields of effort physiology and tracking of certain haematological parameters, such as cholesterol, blood sugar and stress hormones - adrenaline, noradrenalin, cortisol. Thus, we could carry out an even more in depth research of the connection between lifestyle and burnout.

An online health-promoting community (OHPC) has the potential to promote health and advance new means of dialogue between public health representatives and the general public. The aim of this study was to examine what aspects of an OHPC that are critical for satisfying the needs of the user community and public health goals and service capabilities. Community-based participatory research methods were used for data collection and analysis, and participatory design principles to develop a case study OHPC for adolescents. Qualitative data from adolescents on health appraisals and perspectives on health information were collected in a Swedish health service region and classified into categories of user health information exchange needs. A composite design rationale for the OHPC was completed by linking the identified user needs, user-derived requirements, and technical and organizational systems solutions. Conflicts between end-user requirements and organizational goals and resources were identified. The most prominent health information needs were associated to food, exercise, and well-being. The assessment of the design rationale document and prototype in light of the regional public health goals and service capabilities showed that compromises were needed to resolve conflicts involving the management of organizational resources and responsibilities. The users wanted to discuss health issues with health experts having little time to set aside to the OHPC and it was unclear who should set the norms for the online discussions. OHPCs can be designed to satisfy both the needs of user communities and public health goals and service capabilities. Compromises are needed to resolve conflicts between users' needs to discuss health issues with domain experts and the management of resources and responsibilities in public health organizations.

Choose Your Own Adventure: Designing an Environment that Supports NASA Scientists' Goals in Education, Outreach, and Inreach

Science.gov (United States)

DeWitt, S.

2015-12-01

What is your communication goal? That is the opening question asked in NASA's first agency-wide science communication leadership development program. Many scientists know what they want to communicate, some know to whom they'd like to communicate, but few can clearly express why they want to do it. So what? First, being clear about one's goal is critical in being able to measure success. Second, when asked to think critically about communication goals, some scientists may shift their communication behaviors and practices to better achieve those goals. To that end, NASA has designed a deep learning experience for scientists (and engineers and others) to: critically examine their communication goals; learn techniques for getting to know their intended audience; and develop and apply specific communication skills to a project of their choice. Participants in this program come into the classroom with projects that span a wide spectrum including: formal and informal education, public outreach, media interviews, public speaking, stakeholder briefings, and internal awareness-building. Through expert advisors, professional coaches and peer networks, this program provides a supportive environment for individuals to workshop their project in the classroom and receive feedback before, during, and after the project is complete. This program also provides an opportunity for scientists and other participants to learn more about communication at NASA, and to directly influence the agency's science communication culture through action learning. In this presentation, I will summarize NASA's dual-design science communication leadership development program and present some lessons-learned, participant feedback and evaluation data from the initial course offerings.

Full Text Available The purpose of this paper is to give to public institution Web designers a better understanding of the citizens’ objectives when accessing a Web page. Understanding citizen online goals is critical because it gets to the heart of what the public institution website should or could “do.” Approach: The challenge for e-marketers is that for most agencies/institutions, there are likely to be multiple goals that represent the “reason why” citizens could come to the website. For example, a national theatre website might be very effective for people who have already been there, they know effectively what place is the best, who are the actors, etc. Research limitations: The nature of a public institution activity almost dictates the different types of goals that consumers have when visiting the site. It is clear that a citizen has a different goal when accessing a theatre Web page or when he’s accessing a municipality Web page. This is the biggest impediment for drawing a good conceptual model for a public institution Web page. Practical implications: there are likely to be many other goals that could lead people to visit the site, like receiving customer service or leaving a remark.

1998-01-01

The procedure for the analysis (with overpotential correction) of multitube AMTEC (Alkali Metal Thermal-to-Electrical Conversion) cells described in Paper IECEC 98-243 was applied to a wide range of multicell radioisotope space power systems. System design options consisting of one or two generators, each with 2, 3, or 4 stacked GPHS (General Purpose Heat Source) modules, identical to those used on previous NASA missions, were analyzed and performance-mapped. The initial generators analyzed by OSC had 8 AMTEC cells on each end of the heat source stack, with five beta-alumina solid electrolyte (BASE) tubes per cell. The heat source and converters in the Orbital generator designs are embedded in a thermal insulation system consisting of Min-K fibrous insulation surrounded by graded-length molybdenum multifoils. Detailed analyses in previous Orbital studies found that such an insulation system could reduce extraneous heat losses to about 10%. For the above design options, the present paper presents the system mass and performance (i.e., the EOM system efficiency and power output and the BOM evaporator and clad temperatures) for a wide range of heat inputs and load voltages, and compares the results with JPL's preliminary goals for the Europa Orbiter mission to be launched in November 2003. The analytical results showed that the initial 16-cell generator designs resulted in either excessive evaporator and clad temperatures and/or insufficient power outputs to meet the JPL-specified mission goals. The computed performance of modified OSC generators with different numbers of AMTEC cells, cell diameters, cell lengths, cell materials, BASE tube lengths, and number of tubes per cell are described in Paper IECEC.98.245 in these proceedings

A key step in the successful implementation of the integrated approach is the definition of the overall plant-level goals. To be effective, the goals should provide clear statements of what is to be achieved by the plant. This can be contrasted to the current practice of providing design-prescriptive criteria which implicitly address some higher-level objective but restrict the designer's flexibility. Furthermore, the goals should be quantifiable in such a way that satisfaction of the goal can be measured. In the discussion presented, two such plant-level goals adopted for the HTGR and addressing the impact of unscheduled occurrences are described. 1 fig

Ntoumanis, Nikos; Thøgersen-Ntoumani, Cecilie; Smith, Alison L

2009-11-01

Elliot and colleagues (2006) examined the effects of experimentally induced achievement goals, proposed by the trichotomous model, on self-handicapping and performance in physical education. Our study replicated and extended the work of Elliot et al. by experimentally promoting all four goals proposed by the 2 x 2 model (Elliot & McGregor, 2001), measuring the participants' own situational achievement goals, using a relatively novel task, and testing the participants in a group setting. We used a randomized experimental design with four conditions that aimed to induce one of the four goals advanced by the 2 x 2 model. The participants (n = 138) were undergraduates who engaged in a dart-throwing task. The results pertaining to self-handicapping partly replicated Elliot and colleagues' findings by showing that experimentally promoted performance-avoidance goals resulted in less practice. In contrast, the promotion of mastery-avoidance goals did not result in less practice compared with either of the approach goals. Dart-throwing performance did not differ among the four goal conditions. Personal achievement goals did not moderate the effects of experimentally induced goals on self-handicapping and performance. The extent to which mastery-avoidance goals are maladaptive is discussed, as well as the interplay between personal and experimentally induced goals.

An ideal myoelectric prosthetic hand should have the ability to continuously morph between any posture like an anatomical hand. This paper describes the design and validation of a morphing myoelectric hand controller based on principal component analysis of human grasping. The controller commands continuously morphing hand postures including functional grasps using between two and four surface electromyography (EMG) electrodes pairs. Four unique maps were developed to transform the EMG control signals in the principal component domain. A preliminary validation experiment was performed by 10 nonamputee subjects to determine the map with highest performance. The subjects used the myoelectric controller to morph a virtual hand between functional grasps in a series of randomized trials. The number of joints controlled accurately was evaluated to characterize the performance of each map. Additional metrics were studied including completion rate, time to completion, and path efficiency. The highest performing map controlled over 13 out of 15 joints accurately.

A goal programming approach for a joint design of macroeconomic and environmental policies: a methodological proposal and an application to the Spanish economy.

André, Francisco J; Cardenete, M Alejandro; Romero, Carlos

2009-05-01

The economic policy needs to pay increasingly more attention to the environmental issues, which requires the development of methodologies able to incorporate environmental, as well as macroeconomic, goals in the design of public policies. Starting from this observation, this article proposes a methodology based upon a Simonian satisficing logic made operational with the help of goal programming (GP) models, to address the joint design of macroeconomic and environmental policies. The methodology is applied to the Spanish economy, where a joint policy is elicited, taking into consideration macroeconomic goals (economic growth, inflation, unemployment, public deficit) and environmental goals (CO(2), NO( x ) and SO( x ) emissions) within the context of a computable general equilibrium model. The results show how the government can "fine-tune" its policy according to different criteria using GP models. The resulting policies aggregate the environmental and the economic goals in different ways: maximum aggregate performance, maximum balance and a lexicographic hierarchy of the goals.

Multiple goals, motivation and academic learning.

The type of academic goals pursued by students is one of the most important variables in motivational research in educational contexts. Although motivational theory and research have emphasised the somewhat exclusive nature of two types of goal orientation (learning goals versus performance goals), some studies (Meece, 1994; Seifert, 1995, 1996) have shown that the two kinds of goals are relatively complementary and that it is possible for students to have multiple goals simultaneously, which guarantees some flexibility to adapt more efficaciously to various contexts and learning situations. The principal aim of this study is to determine the academic goals pursued by university students and to analyse the differences in several very significant variables related to motivation and academic learning. Participants were 609 university students (74% women and 26% men) who filled in several questionnaires about the variables under study. We used cluster analysis ('quick cluster analysis' method) to establish the different groups or clusters of individuals as a function of the three types of goals (learning goals, performance goals, and social reinforcement goals). By means of MANOVA, we determined whether the groups or clusters identified were significantly different in the variables that are relevant to motivation and academic learning. Lastly, we performed ANOVA on the variables that revealed significant effects in the previous analysis. Using cluster analysis, three groups of students with different motivational orientations were identified: a group with predominance of performance goals (Group PG: n = 230), a group with predominance of multiple goals (Group MG: n = 238), and a group with predominance of learning goals (Group LG: n = 141). Groups MG and LG attributed their success more to ability, they had higher perceived ability, they took task characteristics into account when planning which strategies to use in the learning process, they showed higher persistence

A practical approach to programmatic assessment design.

Science.gov (United States)

Timmerman, A A; Dijkstra, J

2017-12-01

Assessment of complex tasks integrating several competencies calls for a programmatic design approach. As single instruments do not provide the information required to reach a robust judgment of integral performance, 73 guidelines for programmatic assessment design were developed. When simultaneously applying these interrelated guidelines, it is challenging to keep a clear overview of all assessment activities. The goal of this study was to provide practical support for applying a programmatic approach to assessment design, not bound to any specific educational paradigm. The guidelines were first applied in a postgraduate medical training setting, and a process analysis was conducted. This resulted in the identification of four steps for programmatic assessment design: evaluation, contextualisation, prioritisation and justification. Firstly, the (re)design process starts with sufficiently detailing the assessment environment and formulating the principal purpose. Key stakeholders with sufficient (assessment) expertise need to be involved in the analysis of strengths and weaknesses and identification of developmental needs. Central governance is essential to balance efforts and stakes with the principal purpose and decide on prioritisation of design decisions and selection of relevant guidelines. Finally, justification of assessment design decisions, quality assurance and external accountability close the loop, to ensure sound underpinning and continuous improvement of the assessment programme.

Safety goals for nuclear power plant operation

International Nuclear Information System (INIS)

1983-05-01

This report presents and discusses the Nuclear Regulatory Commission's, Policy Statement on Safety Goals for the Operation of Nuclear Power Plants. The safety goals have been formulated in terms of qualitative goals and quantitative design objectives. The qualitative goals state that the risk to any individual member of the public from nuclear power plant operation should not be a significant contributor to that individual's risk of accidental death or injury and that the societal risks should be comparable to or less than those of viable competing technologies. The quantitative design objectives state that the average risks to individual and the societal risks of nuclear power plant operation should not exceed 0.1% of certain other risks to which members of the US population are exposed. A subsidiary quantitative design objective is established for the frequency of large-scale core melt. The significance of the goals and objectives, their bases and rationale, and the plan to evaluate the goals are provided. In addition, public comments on the 1982 proposed policy statement and responses to a series of questions that accompanied the 1982 statement are summarized

Presseau, Justin; Tait, Richard I; Johnston, Derek W; Francis, Jill J; Sniehotta, Falko F

2013-12-01

To test whether perceptions of conflicting and facilitating personal goals, and actual daily time spent in their pursuit, predict accelerometer-assessed physical activity (PA). A prospective multilevel design with a daily accelerometer-based assessment of PA over 1 week was used (N = 106). Participants' personal goals were elicited using personal projects analysis. Participants then rated their personal goals in terms of how they were perceived to facilitate and conflict with their regular PA. Items assessing PA-specific intention and perceived behavioral control (PBC) were also embedded within the baseline measures. For the subsequent 7 consecutive days, participants completed a daily diary based on the day reconstruction method, indicating the time spent in daily episodes involving each of their personal goals, and wore an RT3 tri-axial accelerometer. The main outcome was accelerometer-assessed daily time spent in moderate to vigorous physical activity (MVPA). Random intercept multilevel models indicated that perceived goal facilitation, but not perceived goal conflict, predicted MVPA over and above intention and PBC. Daily time pursuing conflicting goals negatively predicted MVPA when subsequently added to the model and in so doing, attenuated the association between perceived goal facilitation and MVPA. Perceived goal facilitation predicts objectively measured PA over and above intention and PBC, but daily time spent in pursuit of conflicting personal goals provides a better account of how alternative goals relate to engaging in regular PA.

Implementation of safety goals in NRC's regulatory process

International Nuclear Information System (INIS)

Murley, T.E.

1985-01-01

In May 1983 the Nuclear Regulatory Commission issued a policy statement on Safety Goals For Nuclear Power Plant Operation. The Commission at the same time judged that a two-year evaluation period was necessary to judge the effectiveness of the goals and design objectives, and directed the staff to develop information and understanding as to how to further define and use the design objectives and the cost-benefit guidelines. In carrying out the Commission's mandate, the staff framed three major questions to be addressed during the safety goal evaluation period. These three questions are: 1) to what extent is it practical to use safety goals in the regulatory process. 2) Should the quantitative design objectives be modified or supplemented. If so, how. 3) How should the safety goals be implemented at the end of the evaluation period. The staff's conclusions are discussed

A Verification Logic for GOAL Agents

Science.gov (United States)

Hindriks, K. V.

Although there has been a growing body of literature on verification of agents programs, it has been difficult to design a verification logic for agent programs that fully characterizes such programs and to connect agent programs to agent theory. The challenge is to define an agent programming language that defines a computational framework but also allows for a logical characterization useful for verification. The agent programming language GOAL has been originally designed to connect agent programming to agent theory and we present additional results here that GOAL agents can be fully represented by a logical theory. GOAL agents can thus be said to execute the corresponding logical theory.

Flexible goal attribution in early mindreading.

Science.gov (United States)

Michael, John; Christensen, Wayne

2016-03-01

The 2-systems theory developed by Apperly and Butterfill (2009; Butterfill & Apperly, 2013) is an influential approach to explaining the success of infants and young children on implicit false-belief tasks. There is extensive empirical and theoretical work examining many aspects of this theory, but little attention has been paid to the way in which it characterizes goal attribution. We argue here that this aspect of the theory is inadequate. Butterfill and Apperly's characterization of goal attribution is designed to show how goals could be ascribed by infants without representing them as related to other psychological states, and the minimal mindreading system is supposed to operate without employing flexible semantic-executive cognitive processes. But research on infant goal attribution reveals that infants exhibit a high degree of situational awareness that is strongly suggestive of flexible semantic-executive cognitive processing, and infants appear moreover to be sensitive to interrelations between goals, preferences, and beliefs. Further, close attention to the structure of implicit mindreading tasks--for which the theory was specifically designed--indicates that flexible goal attribution is required to succeed. We conclude by suggesting 2 approaches to resolving these problems. (c) 2016 APA, all rights reserved).

Harkin, Benjamin; Webb, Thomas L; Chang, Betty P I; Prestwich, Andrew; Conner, Mark; Kellar, Ian; Benn, Yael; Sheeran, Paschal

2016-02-01

Control theory and other frameworks for understanding self-regulation suggest that monitoring goal progress is a crucial process that intervenes between setting and attaining a goal, and helps to ensure that goals are translated into action. However, the impact of progress monitoring interventions on rates of behavioral performance and goal attainment has yet to be quantified. A systematic literature search identified 138 studies (N = 19,951) that randomly allocated participants to an intervention designed to promote monitoring of goal progress versus a control condition. All studies reported the effects of the treatment on (a) the frequency of progress monitoring and (b) subsequent goal attainment. A random effects model revealed that, on average, interventions were successful at increasing the frequency of monitoring goal progress (d+ = 1.98, 95% CI [1.71, 2.24]) and promoted goal attainment (d+ = 0.40, 95% CI [0.32, 0.48]). Furthermore, changes in the frequency of progress monitoring mediated the effect of the interventions on goal attainment. Moderation tests revealed that progress monitoring had larger effects on goal attainment when the outcomes were reported or made public, and when the information was physically recorded. Taken together, the findings suggest that monitoring goal progress is an effective self-regulation strategy, and that interventions that increase the frequency of progress monitoring are likely to promote behavior change.

Informing principal policy reforms in South Africa through data-based evidence

Directory of Open Access Journals (Sweden)

Gabrielle Wills

2015-12-01

Full Text Available In the past decade there has been a notable shift in South African education policy that raises the value of school leadership as a lever for learning improvements. Despite a growing discourse on school leadership, there has been a lack of empirical based evidence on principals to inform, validate or debate the efficacy of proposed policies in raising the calibre of school principals. Drawing on findings from a larger study to understand the labour market for school principals in South Africa, this paper highlights four overarching characteristics of this market with implications for informing principal policy reforms. The paper notes that improving the design and implementation of policies guiding the appointment process for principals is a matter of urgency. A substantial and increasing number of principal replacements are taking place across South African schools given a rising age profile of school principals. In a context of low levels of principal mobility and high tenure, the leadership trajectory of the average school is established for nearly a decade with each principal replacement. Evidence-based policy making has a strong role to play in getting this right.

Unique characteristics of nursing homes (NHs) contribute to high rates of inappropriate antibiotic use for asymptomatic bacteriuria (ASB), a benign condition. A mobile clinical decision support system (CDSS) may support NH staff in differentiating urinary tract infections (UTI) from ASB and reducing antibiotic days. We used Goal-Directed Design to: 1) Characterize information needs for UTI identification and management in NHs; 2) Develop UTI Decide, a mobile CDSS prototype informed by personas and scenarios of use constructed from Aim 1 findings; 3) Evaluate the UTI Decide prototype with NH staff. Focus groups were conducted with providers and nurses in NHs in Denver, Colorado (n= 24). Qualitative descriptive analysis was applied to focus group transcripts to identify information needs and themes related to mobile clinical decision support for UTI identification and management. Personas representing typical end users were developed; typical clinical context scenarios were constructed using information needs as goals. Usability testing was performed using cognitive walk-throughs and a think-aloud protocol. Four information needs were identified including guidance regarding resident assessment; communication with providers; care planning; and urine culture interpretation. Design of a web-based application incorporating a published decision support algorithm for evidence-based UTI diagnoses proceeded with a focus on nursing information needs during resident assessment and communication with providers. Certified nursing assistant (CNA) and registered nurse (RN) personas were constructed in 4 context scenarios with associated key path scenarios. After field testing, a high fidelity prototype of UTI Decide was completed and evaluated by potential end users. Design recommendations and content recommendations were elicited. Goal-Directed Design informed the development of a mobile CDSS supporting participant-identified information needs for UTI assessment and communication

Kim, Hyoung-Gook; Roeber, Steffen; Samour, Amjad; Sikora, Thomas

2005-01-01

In this paper, we present an automatic extraction of goal events in soccer videos by using audio track features alone without relying on expensive-to-compute video track features. The extracted goal events can be used for high-level indexing and selective browsing of soccer videos. The detection of soccer video highlights using audio contents comprises three steps: 1) extraction of audio features from a video sequence, 2) event candidate detection of highlight events based on the information provided by the feature extraction Methods and the Hidden Markov Model (HMM), 3) goal event selection to finally determine the video intervals to be included in the summary. For this purpose we compared the performance of the well known Mel-scale Frequency Cepstral Coefficients (MFCC) feature extraction method vs. MPEG-7 Audio Spectrum Projection feature (ASP) extraction method based on three different decomposition methods namely Principal Component Analysis( PCA), Independent Component Analysis (ICA) and Non-Negative Matrix Factorization (NMF). To evaluate our system we collected five soccer game videos from various sources. In total we have seven hours of soccer games consisting of eight gigabytes of data. One of five soccer games is used as the training data (e.g., announcers' excited speech, audience ambient speech noise, audience clapping, environmental sounds). Our goal event detection results are encouraging.

Designing and optimising anaerobic digestion systems: A multi-objective non-linear goal programming approach

International Nuclear Information System (INIS)

Nixon, J.D.

2016-01-01

This paper presents a method for optimising the design parameters of an anaerobic digestion (AD) system by using first-order kinetics and multi-objective non-linear goal programming. A model is outlined that determines the ideal operating tank temperature and hydraulic retention time, based on objectives for minimising levelised cost of electricity, and maximising energy potential and feedstock mass reduction. The model is demonstrated for a continuously stirred tank reactor processing food waste in two case study locations. These locations are used to investigate the influence of different environmental and economic climates on optimal conditions. A sensitivity analysis is performed to further examine the variation in optimal results for different financial assumptions and objective weightings. The results identify the conditions for the preferred tank temperature to be in the psychrophilic, mesophilic or thermophilic range. For a tank temperature of 35 °C, ideal hydraulic retention times, in terms of achieving a minimum levelised electricity cost, were found to range from 29.9 to 33 days. Whilst there is a need for more detailed information on rate constants for use in first-order models, multi-objective optimisation modelling is considered to be a promising option for AD design. - Highlights: • Nonlinear goal programming is used to optimise anaerobic digestion systems. • Multiple objectives are set including minimising the levelised cost of electricity. • A model is developed and applied to case studies for the UK and India. • Optimal decisions are made for tank temperature and retention time. • A sensitivity analysis is carried out to investigate different model objectives.

2017-11-01

Full Text Available Purpose: To survey structural designs of x-ray rooms and compliance to shielding design goals of three x-ray imaging facilities. Methods and Materials: The survey was conducted in three radiodiagnostic centers in South East Nigeria, labeled X, Y and Z for anonymity. A stretchable non-elastic meter rule was used to measure x-ray room dimensions. A Vernier caliper was used to measure lead thickness while a calibrated digital survey meter Radalert 100x was used for radiation survey of controlled and uncontrolled areas. Simple statistical tools such as mean and standard deviation were used for analysis with the aid of Microsoft Excel version 2007. Results: Center X had a room dimension of 2.4 m × 2.1 m, Center Y had an x-ray room dimension of 3.6 m × 3.3 m, and Center Z had two x-ray rooms with identical dimensions of 6.3 m × 3.6 m. Measured exit radiation doses for controlled areas in all the centers were: 0.00152 mSv/wk; 0.00496 mSv/wk; 0.00168 mSv/wk; 0.00224 mSv/wk respectively. Lead was the common shielding material used. Conclusion: Based on the parameters studied, Center Z had the ideal room size and layout. Relative distances from the x-ray tubes to the nearest walls were not optimized in all the centers except in Center Z. Measured exit doses were within recommended limits except in Center Y. The location of the control consoles and measured doses were appropriate and within recommended design goals.

Principal stratification in causal inference.

Science.gov (United States)

Frangakis, Constantine E; Rubin, Donald B

2002-03-01

Many scientific problems require that treatment comparisons be adjusted for posttreatment variables, but the estimands underlying standard methods are not causal effects. To address this deficiency, we propose a general framework for comparing treatments adjusting for posttreatment variables that yields principal effects based on principal stratification. Principal stratification with respect to a posttreatment variable is a cross-classification of subjects defined by the joint potential values of that posttreatment variable tinder each of the treatments being compared. Principal effects are causal effects within a principal stratum. The key property of principal strata is that they are not affected by treatment assignment and therefore can be used just as any pretreatment covariate. such as age category. As a result, the central property of our principal effects is that they are always causal effects and do not suffer from the complications of standard posttreatment-adjusted estimands. We discuss briefly that such principal causal effects are the link between three recent applications with adjustment for posttreatment variables: (i) treatment noncompliance, (ii) missing outcomes (dropout) following treatment noncompliance. and (iii) censoring by death. We then attack the problem of surrogate or biomarker endpoints, where we show, using principal causal effects, that all current definitions of surrogacy, even when perfectly true, do not generally have the desired interpretation as causal effects of treatment on outcome. We go on to forrmulate estimands based on principal stratification and principal causal effects and show their superiority.

Price, Deborah; Tschannen, Dana; Caylor, Shandra

2013-09-01

New strategies are emerging to promote structure and increase learning in the clinical setting. Nursing faculty designed a mechanism by which integrative learning and situated coaching could occur more readily in the clinical setting. The Clinical Goals Initiative was implemented for sophomore-, junior-, and senior-level students in their clinical practicums. Students developed weekly goals reflecting three domains of professional nursing practice. Goals were shared with faculty and staff nurse mentors at the beginning of the clinical day to help guide students and mentors with planning for learning experiences. After 6 weeks, faculty and students were surveyed to evaluate project effectiveness. Faculty indicated that goal development facilitated clinical learning by providing more student engagement, direction, and focus. Students reported that goal development allowed them to optimize clinical learning opportunities and track their growth and progress. Faculty and students indicated the goals promoted student self-learning, autonomy, and student communication with nurse mentors and faculty. Copyright 2013, SLACK Incorporated.

Principal permeability determination from multiple horizontal well tests

Energy Technology Data Exchange (ETDEWEB)

Economides, M. [Texas A and M Univ., TX (United States); Munoz, A.; Ehlig-Economides, C.

1998-12-31

A method for obtaining principal permeability magnitudes and direction that requires only the linear flow regime from transient tests in three horizontal wells oriented in three distinct and arbitrary directions, is described. Well design optimization strategies require knowledge of both the principal permeability orientation as well as the horizontal permeability magnitudes. When the degree of horizontal permeability anisotropy (i.e. permeability in the bedding plane with respect to direction) is significant, the productivity of a long horizontal well will depend greatly on its direction, especially when the well is first brought into production. Productivities have been found to deviate substantially among wells in the same reservoir and this deviation has been attributed to differences in well orientation. In view of this fact, measuring permeability anisotropy becomes a compelling necessity. The success of the proposed method is illustrated by a case study in which the principal permeability magnitudes and direction from three wells were used to predict the productivity of a fourth well within 10 per cent. Use of the computed principal permeabilities from the case study, it was possible to forecast the cumulative production to show the significance of well trajectory optimization on the discounted cash flow and the net present value. 20 refs., 3 figs.

Trajectory modeling of gestational weight: A functional principal component analysis approach.

Directory of Open Access Journals (Sweden)

Menglu Che

Full Text Available Suboptimal gestational weight gain (GWG, which is linked to increased risk of adverse outcomes for a pregnant woman and her infant, is prevalent. In the study of a large cohort of Canadian pregnant women, our goals are to estimate the individual weight growth trajectory using sparsely collected bodyweight data, and to identify the factors affecting the weight change during pregnancy, such as prepregnancy body mass index (BMI, dietary intakes and physical activity. The first goal was achieved through functional principal component analysis (FPCA by conditional expectation. For the second goal, we used linear regression with the total weight gain as the response variable. The trajectory modeling through FPCA had a significantly smaller root mean square error (RMSE and improved adaptability than the classic nonlinear mixed-effect models, demonstrating a novel tool that can be used to facilitate real time monitoring and interventions of GWG. Our regression analysis showed that prepregnancy BMI had a high predictive value for the weight changes during pregnancy, which agrees with the published weight gain guideline.

Optimal dietary patterns designed from local foods to achieve maternal nutritional goals.

Raymond, Jofrey; Kassim, Neema; Rose, Jerman W; Agaba, Morris

2018-04-04

Achieving nutritional requirements for pregnant and lactating mothers in rural households while maintaining the intake of local and culture-specific foods can be a difficult task. Deploying a linear goal programming approach can effectively generate optimal dietary patterns that incorporate local and culturally acceptable diets. The primary objective of this study was to determine whether a realistic and affordable diet that achieves nutritional goals for rural pregnant and lactating women can be formulated from locally available foods in Tanzania. A cross sectional study was conducted to assess dietary intakes of 150 pregnant and lactating women using a weighed dietary record (WDR), 24 h dietary recalls and a 7-days food record. A market survey was also carried out to estimate the cost per 100 g of edible portion of foods that are frequently consumed in the study population. Dietary survey and market data were then used to define linear programming (LP) model parameters for diet optimisation. All LP analyses were done using linear program solver to generate optimal dietary patterns. Our findings showed that optimal dietary patterns designed from locally available foods would improve dietary adequacy for 15 and 19 selected nutrients in pregnant and lactating women, respectively, but inadequacies remained for iron, zinc, folate, pantothenic acid, and vitamin E, indicating that these are problem nutrients (nutrients that did not achieve 100% of their RNIs in optimised diets) in the study population. These findings suggest that optimal use of local foods can improve dietary adequacy for rural pregnant and lactating women aged 19-50 years. However, additional cost-effective interventions are needed to ensure adequate intakes for the identified problem nutrients.

2017-06-01

Full Text Available In recent years, there has been an increasing interest to use smart devices’ drawing games for educational benefit. In Indonesia, our government classifies children age four to six years old as preschool children. Not all preschool children can use drawing games easily. Further, drawing games may not fulfill all Indonesia's preschool children’s drawing competencies. This research proposes to use Goal-Question Metric (GQM to investigate and evaluate interaction design patterns of preschool children in order to achieve the drawing competencies for preschool children in two drawing Android-based games: Belajar Menggambar (in English: Learn to Draw and Coret: Belajar Menggambar (in English: Scratch: Learn to Draw. We collected data from nine students of a preschool children education in a user research. The results show that GQM can assist to evaluate interaction design patterns in achieving the drawing competencies. Our approach can also yield interaction design patterns by comparing interaction design patterns in two drawing games used.

2018-02-01

The Ionospheric Connection Explorer, or ICON, is a new NASA Explorer mission that will explore the boundary between Earth and space to understand the physical connection between our world and our space environment. This connection is made in the ionosphere, which has long been known to exhibit variability associated with the sun and solar wind. However, it has been recognized in the 21st century that equally significant changes in ionospheric conditions are apparently associated with energy and momentum propagating upward from our own atmosphere. ICON's goal is to weigh the competing impacts of these two drivers as they influence our space environment. Here we describe the specific science objectives that address this goal, as well as the means by which they will be achieved. The instruments selected, the overall performance requirements of the science payload and the operational requirements are also described. ICON's development began in 2013 and the mission is on track for launch in 2018. ICON is developed and managed by the Space Sciences Laboratory at the University of California, Berkeley, with key contributions from several partner institutions.

The Structure and Application of High Level Safety Goals. A Review by the MDEP Sub-committee on Safety Goals

International Nuclear Information System (INIS)

2011-01-01

One of the aims of MDEP is to work towards greater harmonisation of regulatory requirements. To achieve this aim, it is necessary that there is a degree of convergence on the safety goals that are required to be met by designers and operators. The term 'safety goals' is defined to cover all health and safety requirements which must be met: these may be deterministic rules and/or probabilistic targets. They should cover the safety of workers, public and the environment in line with the IAEA's Basic Safety Objective; encompassing safety in normal operation through to severe accidents. All regulators have safety goals, but these are expressed in many different ways and exercises in comparing them frequently are done at a very low level eg specific temperatures in the reactor vessel. The differences in the requirements from different regulators are difficult to resolve as the goals are derived using different principles and assumptions and are for a specific technology. Therefore MDEP set up a sub-committee to investigate a different approach. This approach was to start with the top level goals and to derive a structure and means of deriving lower tier goals that can be seen to be clearly related to the higher level ones. This approach has the potential to greatly assist in the process of harmonisation of regulatory requirements. The paper reviews the high level goals used in MDEP countries and the relevant work of international groups. From these it draws broad conclusions that the form of the framework should be an Hierarchical Structure of Safety Goals, incorporating an extended Defense-in-Depth approach. The basis concept is that the higher level safety goals can then developed, in a coherent and consistent manner, into lower level safety goals and targets that can be applied within the design and operation of reactors, with a clear connection between the different levels. This structured approach is technology-neutral and is sufficiently flexible that it can be

Goal motives and multiple-goal striving in sport and academia: A person-centered investigation of goal motives and inter-goal relations.

Science.gov (United States)

Healy, Laura C; Ntoumanis, Nikos; Duda, Joan L

2016-12-01

This investigation extended the goal striving literature by examining motives for two goals being pursued simultaneously. Grounded in self-determination theory, we examined how student-athletes' motives for their sporting and academic goals were associated with inter-goal facilitation and interference. Cross-sectional survey. UK university student-athletes (n=204) identified their most important sporting and academic goals. They then rated their extrinsic, introjected, identified and intrinsic motives for these goals and completed questionnaires assessing inter-goal facilitation and interference. Using a person-centered approach via latent profile analysis, we identified three distinct profiles of goal motives. Auxiliary analyses showed that the profile with high identified motives for both goals reported greater inter-goal facilitation. Extending the previous literature, the findings demonstrate the benefits of autonomous motives when simultaneously pursing goals in sport and academia. Copyright © 2016. Published by Elsevier Ltd.

Fast principal component analysis for stacking seismic data

Science.gov (United States)

Wu, Juan; Bai, Min

2018-04-01

Stacking seismic data plays an indispensable role in many steps of the seismic data processing and imaging workflow. Optimal stacking of seismic data can help mitigate seismic noise and enhance the principal components to a great extent. Traditional average-based seismic stacking methods cannot obtain optimal performance when the ambient noise is extremely strong. We propose a principal component analysis (PCA) algorithm for stacking seismic data without being sensitive to noise level. Considering the computational bottleneck of the classic PCA algorithm in processing massive seismic data, we propose an efficient PCA algorithm to make the proposed method readily applicable for industrial applications. Two numerically designed examples and one real seismic data are used to demonstrate the performance of the presented method.

2013-04-01

The school nurse plays a crucial role in the provision of comprehensive health services to students. This role encompasses both health and educational goals. The perception of the school nurse's role and its relation to health promotion is fundamental to the development of school nursing. This study aimed to determine the perception of school nurses and principals toward the role of school nurses in providing school health services in Qatar. A cross-sectional study was carried out among all school nurses (n=159) and principals (n=159) of governmental schools in Qatar. The participants were assessed for their perception toward the role of the school nurse in the school using 19-Likert-type scaled items Questionnaire. The response rates were 100% for nurses and 94% for principals. The most commonly perceived roles of the school nurse by both nurses and principals were 'following up of chronically ill students', 'providing first aid', and 'referral of students with health problems', whereas most of the roles that were not perceived as school nurse roles were related to student academic achievements. School nurses and principals agreed on the clinical/medical aspects of nurses' role within schools, but disagreed on nurses' involvement in issues related to the school performance of students. The study recommends raising awareness of school principals on the school nursing role, especially in issues related to the school performance of students.

Path to development of quantitative safety goals

International Nuclear Information System (INIS)

Joksimovic, V.; Houghton, W.J.

1980-04-01

There is a growing interest in defining numerical safety goals for nuclear power plants as exemplified by an ACRS recommendation. This paper proposes a lower frequency limit of approximately 10 -4 /reactor-year for design basis events. Below this frequency, down, to a small frequency such as 10 -5 /reactor-year, safety margin can be provided by, say, site emergency plans. Accident sequences below 10 -5 should not impact public safety, but it is prudent that safety research programs examine sequences with significant consequences. Once tentatively agreed upon, quantitative safety goals together with associated implementation tools would be factored into regulatory and design processes

In order to provide insights for improvement of work in control rooms several factors have to be considered. Knowledge of principles including control room philosophies will guide the recommended improvements. In addition to knowledge about specific principles an advantage for an organization can be an understanding of similarities and policies used in other high risk industry. The report has been developed on the basis of a document analysis of international standards and other guiding documents. (NUREG 0711, ISO 11064, ISO 6385, IEC 60964). In addition to the document analysis which has strived to compare the documents to see similarities in important principals, experience from working with control room design, modifications and evaluations in other high risk industries has pervaded the report. Important principles have been identified which are recommended to be included in a control room philosophy. Many of these are similar to the principles identified in the international standards. An additional principal which is regarded as important is the utilization of Key Performance Indicators (KPI) which can be used as a measure to target preventative means. Further more it is critical that the control room philosophy is easy to access and comprehend for all users. One of the challenges that remain after having developed a control room philosophy is how to utilize it in the daily work situation. It is vital that the document remains as a living document, guiding the continual improvement of the control room in the various life cycle stages.

Bishop, W.P.; Hoos, I.R.; McGrath, P.E.; Metlay, D.S.; Stoneman, W.C.

1978-05-01

A special, seven member, interdisciplinary task group of consultants was established in January 1976 to propose goals for the national waste management program. This is the report of that group. The proposed goals are intended as a basis for the NRC to establish a policy by which to guide and coordinate the activities of government, business, and academic organizations whose responsibility it will be to manage radioactive wastes. The report is based on findings, interpretations and analysis by the authors who examined selected primary literature and interviewed many individuals concerned with waste management. The authors extended the scope of their inquiry and proposed goals to cover 'all technical and societal aspects necessary to an operating waste management system, rather than dealing with the regulatory process alone.' The waste management goals as developed are simple statements of principles which appear to the authors to be important conditions to insure the proper establishment and operation of a system to manage radioactive wastes.' In brief, the goals are designed to protect people and things of value in an equitable manner

Achievement Goals and their Underlying Goal Motivation: Does it Matter Why Sport Participants Pursue their Goals?

Directory of Open Access Journals (Sweden)

Patrick Gaudreau

2016-07-01

Full Text Available This study examined whether the good or bad outcomes associated with mastery-approach (MAP and performance-approach (PAP goals depend on the extent to which they are motivated by autonomous or controlled motivation. A sample of 515 undergraduate students who participated in sport completed measures of achievement goals, motivation of achievement goals, perceived goal attainment, sport satisfaction, and both positive and negative affect. Results of moderated regression analyses revealed that the positive relations of both MAP and PAP goals with perceived goal attainment were stronger for athletes pursuing these goals with high level of autonomous goal motivation. Also, the positive relations between PAP goals and both sport satisfaction and positive affect were stronger at high levels of autonomous goal motivation and controlled goal motivation. The shape of all these significant interactions was consistent with tenets of Self-Determination Theory as controlled goal motivation was negatively associated with positive affect and sport satisfaction and positively associated with negative affect. Overall, these findings demonstrated the importance of considering goal motivation in order to better understand the conditions under which achievement goals are associated with better experiential and performance outcomes in the lives of sport participants.

IRIS Responsiveness to Generation IV Road-map Goals

International Nuclear Information System (INIS)

Carelli, M.D.; Paramonov, D.V.; Petrovic, B.

2002-01-01

The DOE Generation IV road-map process is in its second and final year. Almost one hundred concepts submitted from all over the world have been reviewed against the Generation IV goals of resources sustainability; safety and reliability; and, economics. Advanced LWRs are taken as the reference point. IRIS (International Reactor Innovative and Secure), a 100-335 MWe integral light water reactor being developed by a vast international consortium led by Westinghouse, is one on the concepts being considered in the road-map and is perhaps the most visible representative of the concept set known as Integral Primary System Reactors (IPSR). This paper presents how IRIS satisfies the prescribed goals. The first goal of resource sustainability includes criteria like utilization of fuel resources, amount and toxicity of waste produced, environmental impact, proliferation and sabotage resistance. As a thermal reactor IRIS does not have the same fuel utilization as fast reactors. However, it has a significant flexibility in fuel cycles as it is designed to utilize either UO 2 or MOX with straight burn cycles of 4 to 10 years, depending on the fissile content. High discharge burnup and Pu recycling result in good fuel utilization and lower waste; IRIS has also attractive proliferation resistance characteristics, due to the reduced accessibility of the fuel. The safety and reliability goal include reliability, workers' exposure, robust safety features, models with well characterized uncertainty, source term and mechanisms of energy release, robust mitigation of accidents. IRIS is significantly better than advanced LWRs because of its safety by design which eliminates a variety of accidents such as LOCAs, its containment vessel coupled design which maintains the core safely covered during the accident sequences, its design simplification features such as no (or reduced) soluble boron, internal shielding and four-year refueling/maintenance interval which significantly reduce

Goal setting was investigated as part of an implementation trial of an asthma management service (PAMS) conducted in 96 Australian community pharmacies. Patients and pharmacists identified asthma-related issues of concern to the patient and collaboratively set goals to address these. Although goal setting is commonly integrated into disease state management interventions, the nature of goals, and their contribution to goal attainment and health outcomes are not well understood. To identify and describe: 1) goals set collaboratively between adult patients with asthma and their pharmacist, 2) goal specificity and goal achievement, and 3) describe the relationships between specificity, achievement, asthma control and asthma-related quality of life. Measures of goal specificity, and goal achievement were developed and applied to patient data records. Goals set were thematically analyzed into goal domains. Proportions of goals set, goals achieved and their specificity were calculated. Correlational and regression analyses were undertaken to determine the relationships between goal specificity, goal achievement, asthma control and asthma-related quality of life. Data were drawn from 498 patient records. Findings showed that patients set a wide range and number of asthma-related goals (N = 1787) and the majority (93%) were either achieved or being working toward by the end of the study. Goal achievement was positively associated with specific and moderately specific goals, but not non-specific goals. However, on closer inspection, an inconsistent pattern of relationships emerged as a function of goal domain. Findings also showed that goal setting was associated with end-of-study asthma control but not to asthma-related quality of life. Pharmacists can help patients to set achievable and specific asthma management goals, and these have the potential to directly impact health outcomes such as asthma control. Goal specificity appears to be an important feature in the

2017-09-19

A two-level principal component predictor (2L-PCA) was proposed based on the principal component analysis (PCA) approach. It can be used to quantitatively analyze various compounds and peptides about their functions or potentials to become useful drugs. One level is for dealing with the physicochemical properties of drug molecules, while the other level is for dealing with their structural fragments. The predictor has the self-learning and feedback features to automatically improve its accuracy. It is anticipated that 2L-PCA will become a very useful tool for timely providing various useful clues during the process of drug development.

Get a taste of your goals: promoting motive-goal congruence through affect-focus goal fantasy.

Science.gov (United States)

Job, Veronika; Brandstätter, Veronika

2009-10-01

Studies show that motive-goal congruence is an important predictor of well-being (Baumann, Kaschel, & Kuhl, 2005; Brunstein, Schultheiss, & Grässmann, 1998). However, little is known about the factors that promote congruence between implicit motives and goals. Relying on McClelland's (1985) concept of implicit motives and the theory of fantasy realization (Oettingen, 1999), we postulated that goal fantasies focusing on motive-specific affective incentives promote motive-congruent goal setting. This hypothesis was tested in 3 experimental studies. In Study 1 (n=46) and Study 2 (n=48), participants were asked to select goals in a hypothetical scenario. In Study 3 (n=179), they rated their commitment to personal goals for their actual life situation. The results of all 3 studies supported our hypothesis that participants who focus on motive-specific affective incentives in their goal fantasies set their goals in line with their corresponding implicit motive dispositions.

Science.gov (United States)

Severtson, Dolores J

2015-02-01

Barriers to communicating the uncertainty of environmental health risks include preferences for certain information and low numeracy. Map features designed to communicate the magnitude and uncertainty of estimated cancer risk from air pollution were tested among 826 participants to assess how map features influenced judgments of adequacy and the intended communication goals. An uncertain versus certain visual feature was judged as less adequate but met both communication goals and addressed numeracy barriers. Expressing relative risk using words communicated uncertainty and addressed numeracy barriers but was judged as highly inadequate. Risk communication and visual cognition concepts were applied to explain findings.

An analysis of the relationship between K--5 elementary school teachers' perceptions of principal instructional leadership and their science teaching efficacy

Clark, Ian

The purpose of this study is to analyze the relationship between K-5 elementary school teachers' perceptions of principal instructional leadership and their science teaching efficacy. The influence of background variables on both leadership and efficacy is also analyzed. A sequential mixed methods approach was used in this study. The survey sample was comprised of teachers in the elementary divisions of schools from the nine international school regional associations. Teacher participation was obtained through an email containing an online survey link. Following the analysis of survey responses (N=356), in-depth interviews (N=17) were conducted. Reliability for the instructional leadership scale was found to be .94 (coefficient alpha) and .69 for the personal science teaching efficacy (PSTE) scale. The results show a significant correlation between elementary school teachers' perceptions of principal instructional leadership and their PSTE levels, with the most significant correlation that between the study of a science-related major or minor at college and higher PSTE scores. Strong correlations were also found between PSTE levels and having principals who discussed goals at faculty meetings, participated in science curricular review, supported recognition of student progress, encouraged new skills and concepts, discussed student progress with faculty, and used assessments to see science progress towards easily understood goals. PSTE levels were also higher in schools where principals had grade or school level science coordinators in place and where they supported the use of science kits.

Defining safety goals. 2. Basic Consideration on Defining Safety Goals

International Nuclear Information System (INIS)

Hakata, T.

2001-01-01

cancer and severe hereditary effects are 10 x 10 -2 /Sv and 1.3 x10 -2 /Sv, respectively. The basic safety goals can be expressed by the complementary accumulative distribution function (CCDF) of dose versus frequencies of events: Pc(C > Cp) 5 (Cp/Co) -α . The aversion factor a is here expressed by the following arbitrary equation, which gives a polynomial curve of the order of m on a logarithmic plane: α = a+b(log(Cp/Co)) m , where: Pc = CCDF frequency for Cp (/yr), Cp = dose (mSv), Co = Cp for Pc =1, a, b, m = constants. Figure 1 shows a typical tolerable risk profile (risk limit curve), which is drawn so that all the points obtained in the previous discussions are above the curve (Co=1, a=1, b=0.0772, and m = 2). Safety criteria by ANS (Ref. 2) and SHE (Ref. 3) are shown in Fig. 1 for comparison. An aversion of a factor of 2 is resulted between 1 mSv and 1 Sv. No ALARA is included, which must be considered in defining specific safety goals. The frequency of a single class of events must be lower than the CCDF profile, and a curve lower by a factor of 10 is drawn in Fig. 1. The doses referenced in the current Japanese safety guidelines and site criteria are shown in Fig. 1. The referenced doses seem reasonable, considering the conservatism in the analysis of design-basis accidents. Specific safety goals for each sort of facility can be defined based on the basic safety goals, reflecting the characteristics of the facilities and considering ALARA. The indexes of engineering terms, such as CMF and LERF, are preferable for nuclear power plants, although interpretation from dose to the engineering terms is needed. Other indexes may be used (such as frequency of criticality accidents, etc.) for facilities except for power plants. The applicability of safety goals will thus be improved. Figure 2 shows the relative risk factors (1, 1%, and 0.1%) versus the severity of radiation effects. This might indicate the adequacy of the risk factors. The absolute risk limits, which

Objective : To examine the types of life and dietary goals individuals report and how these goal domains interact as framed by goal systems theory. Methods : This work is a cross-sectional survey study. Measures included the incidence of common life and dietary goals and how these goals interact with and facilitate each other. Results : The results of a quantitative survey ( n  = 46 participants), which was informed by two focus groups ( n  = 17 participants), showed that participants are trying to achieve several different life (e.g. achieving financial success) and dietary goals (e.g. eating more fruits and vegetables, drinking more water, and losing weight) and that these two types of goals interact to both facilitate and conflict with each other. Having a life goal of exercising was significantly associated with healthy eating goals when compared with other life goals ( p 's goals may be linked and help to facilitate one another. Being in the maintenance phase with the goal of healthy eating was associated with participants feeling like they were more successful in their other non-diet-related health goals ( p  goals can facilitate success in achieving other goals. Conclusions : Life goals can have an impact on a person's ability to achieve and maintain dietary and other health goals. Health educators may help to facilitate long-term behavior change by examining a person's life goals as well as dietary goals.

To examine the widely accepted hypothesis that farm women are more concerned with safety issues and behaviors than their male counterparts are. A telephone survey was administered to a random sample of Kentucky principal farm operators, 90 of whom were women. Participants were questioned about their tractor safety beliefs and practices. No significant sex differences in tractor safety perceptions and behavior were observed. Socialization of women to the role of principal farm operator may override their typically greater sensitivity to safety issues, an important consideration when designing safety campaigns for this population.

Multiscale principal component analysis

International Nuclear Information System (INIS)

Akinduko, A A; Gorban, A N

2014-01-01

Principal component analysis (PCA) is an important tool in exploring data. The conventional approach to PCA leads to a solution which favours the structures with large variances. This is sensitive to outliers and could obfuscate interesting underlying structures. One of the equivalent definitions of PCA is that it seeks the subspaces that maximize the sum of squared pairwise distances between data projections. This definition opens up more flexibility in the analysis of principal components which is useful in enhancing PCA. In this paper we introduce scales into PCA by maximizing only the sum of pairwise distances between projections for pairs of datapoints with distances within a chosen interval of values [l,u]. The resulting principal component decompositions in Multiscale PCA depend on point (l,u) on the plane and for each point we define projectors onto principal components. Cluster analysis of these projectors reveals the structures in the data at various scales. Each structure is described by the eigenvectors at the medoid point of the cluster which represent the structure. We also use the distortion of projections as a criterion for choosing an appropriate scale especially for data with outliers. This method was tested on both artificial distribution of data and real data. For data with multiscale structures, the method was able to reveal the different structures of the data and also to reduce the effect of outliers in the principal component analysis

Full Text Available Introduction: The main purpose of this study was to assess fulfillment of goals about “Health Transformation Plan (HTP of Ministry of Health, Treatment and Medical Education” from the perspective of managers, which is as one of the most important management challenges in the Health System Reform Plan. These goals included six packages determined by the Ministry of Health, Treatment and Medical Education, the fulfillment of each of which one was evaluated separately as sub-goals in the current study. Finally, the rank of each package in comparison to other packages was determined and presented, using means rank test (Friedman test. Method: This study was conducted using a questionnaire in which comments of the senior and middle managers of Nemazee hospital were collected as the research data. Due to the fact that about one year has passed since the beginning of implementation of HTP and since there were no documented methods or questionnaires, the researcher designed a self-made questionnaire. The basis of designing the questionnaire was the set of guidelines developed for Health System Reform Plan. These guidelines include goals that a hospital should achieve during implementation of Health System Reform Plan. After sharing these goals with senior and middle managers of Nemazee hospital (as the place of research, they were converted to a questionnaire including 20 questions. The questionnaire included the goals that must be achieved in Nemazee hospital of Shiraz during the implementation of the plan. After designing the questionnaire, a preliminary test was taken to assess the reliability. Results: Cronbach’s alpha coefficient (0.88 showed a high rate of reliability in the above questionnaire. After the final data collection, the questionnaire was tested in a sample of 100 senior and middle managers; the results showed that about six packages were specified by the Ministry of Health, Treatment and Medical Education.

The treatment goal algorithm for psoriasis, first originated in 2007, has ever since been adopted into treatment guidelines. It remained unclear how many patients have experienced the use of treatment goals in routine care and how these are perceived. The aim of the pilot study was to get first insight in the use and impact of therapeutic goals in a large cohort of patients with psoriasis in routine care. This study is a multicenter, non-interventional, cross-sectional health care study in n = 213 dermatology centers across Germany. A standardized physician and patient questionnaire was used, including demographics, disease and treatment characteristics. To evaluate patient treatment perception and satisfaction, a questionnaire (PsoSat) addressing 8 specific items was designed. Consistency and validity of the questionnaire were controlled by factor analyses and reliability tests. In total n = 1,883 patients were included for analysis (54.2% male). Mean age was 52 years, mean disease duration 19 years. In total 45.5% (n = 856) stated an improvement of psoriatic symptoms in the last 4 weeks. In patients including treatment goals, the course of psoriasis in the last 4 weeks was rated significantly better and predicted significantly higher patient satisfaction. Patients reporting periodic outcomes measurement of psoriasis treatment, also had significantly better course of disease, higher satisfaction and a lower psoriasis severity. A majority of patients experienced the use of treatment goals in practice. The association of using treatment goals with clinical outcomes and treatment satisfaction was markedly positive. These findings indicate that the use of treatment goals and outcome measurements in fact improve psoriasis management.

Predicting Subsequent Task Performance From Goal Motivation and Goal Failure

Directory of Open Access Journals (Sweden)

Laura Catherine Healy

2015-07-01

Full Text Available Recent research has demonstrated that the cognitive processes associated with goal pursuit can continue to interfere with unrelated tasks when a goal is unfulfilled. Drawing from the self-regulation and goal-striving literatures, the present study explored the impact of goal failure on subsequent cognitive and physical task performance. Furthermore, we examined if the autonomous or controlled motivation underpinning goal striving moderates the responses to goal failure. Athletes (75 male, 59 female, Mage = 19.90 years, SDage = 3.50 completed a cycling trial with the goal of covering a given distance in 8 minutes. Prior to the trial, their motivation was primed using a video. During the trial they were provided with manipulated performance feedback, thus creating conditions of goal success or failure. No differences emerged in the responses to goal failure between the primed motivation or performance feedback conditions. We make recommendations for future research into how individuals can deal with failure in goal striving.

Goal conflict, goal facilitation, and health professionals' provision of physical activity advice in primary care: an exploratory prospective study.

Presseau, Justin; Francis, Jill J; Campbell, Neil C; Sniehotta, Falko F

2011-07-15

The theory of planned behaviour has well-evidenced utility in predicting health professional behaviour, but focuses on a single behaviour isolated from the numerous potentially conflicting and facilitating goal-directed behaviours performed alongside. Goal conflict and goal facilitation may influence whether health professionals engage in guideline-recommended behaviours, and may supplement the predictive power of the theory of planned behaviour. We hypothesised that goal facilitation and goal conflict contribute to predicting primary care health professionals' provision of physical activity advice to patients with hypertension, over and above predictors of behaviour from the theory of planned behaviour. Using a prospective predictive design, at baseline we invited a random sample of 606 primary care health professionals from all primary care practices in NHS Grampian and NHS Tayside (Scotland) to complete postal questionnaires. Goal facilitation and goal conflict were measured alongside theory of planned behaviour constructs at baseline. At follow-up six months later, participants self-reported the number of patients, out of those seen in the preceding two weeks, to whom they provided physical activity advice. Forty-four primary care physicians and nurses completed measures at both time points (7.3% response rate). Goal facilitation and goal conflict improved the prediction of behaviour, accounting for substantial additional variance (5.8% and 8.4%, respectively) in behaviour over and above intention and perceived behavioural control. Health professionals' provision of physical activity advice in primary care can be predicted by perceptions about how their conflicting and facilitating goal-directed behaviours help and hinder giving advice, over and above theory of planned behaviour constructs. Incorporating features of multiple goal pursuit into the theory of planned behaviour may help to better understand health professional behaviour.

Principal Curves on Riemannian Manifolds.

Science.gov (United States)

Hauberg, Soren

2016-09-01

Euclidean statistics are often generalized to Riemannian manifolds by replacing straight-line interpolations with geodesic ones. While these Riemannian models are familiar-looking, they are restricted by the inflexibility of geodesics, and they rely on constructions which are optimal only in Euclidean domains. We consider extensions of Principal Component Analysis (PCA) to Riemannian manifolds. Classic Riemannian approaches seek a geodesic curve passing through the mean that optimizes a criteria of interest. The requirements that the solution both is geodesic and must pass through the mean tend to imply that the methods only work well when the manifold is mostly flat within the support of the generating distribution. We argue that instead of generalizing linear Euclidean models, it is more fruitful to generalize non-linear Euclidean models. Specifically, we extend the classic Principal Curves from Hastie & Stuetzle to data residing on a complete Riemannian manifold. We show that for elliptical distributions in the tangent of spaces of constant curvature, the standard principal geodesic is a principal curve. The proposed model is simple to compute and avoids many of the pitfalls of traditional geodesic approaches. We empirically demonstrate the effectiveness of the Riemannian principal curves on several manifolds and datasets.

Pro-Social Goals in Achievement Situations: Amity Goal Orientation Enhances the Positive Effects of Mastery Goal Orientation.

Science.gov (United States)

Levontin, Liat; Bardi, Anat

2018-04-01

Research has neglected the utility of pro-social goals within achievement situations. In this article, four studies demonstrate that amity goal orientation, promoting mutual success of oneself together with others, enhances the utility of mastery goal orientation. We demonstrate this in longitudinally predicting performance (Studies 1 and 2) and in maintaining motivation after a disappointing performance (Studies 3 and 4). The studies demonstrate the same interaction effect in academic and in work achievement contexts. Specifically, whereas amity goal orientation did not predict achievement on its own, it enhanced the positive effect of mastery goal orientation. Together, these studies establish the importance of amity goal orientation while also advancing our understanding of the effects of other achievement goal orientations. We suggest future directions in examining the utility of amity goals in other contexts.

FOREIGN LANGUAGE TEACHING IN SUDANESE UNIVERSITIES: GOALS, ATTITUDES, AND REALITY

Abdel Rahim Hamid Mugaddam

2012-07-01

Full Text Available Abstract: The goals and means of language study continue in the very center of debates among specialists in language teaching/learning. Different views relating to language and its functions are reflected in two main approaches to language teaching/learning. On the one hand, language is considered to be principally instrumental, a means of communicating thought and information. One the other hand, language is viewed as an important element of human being’s thought processes, perceptions, and self-expressions; and as such, it is placed at the core of translingual and transcultural competence. This paper investigates the current situation of teaching/learning foreign languages in the Sudanese universities with special focus on the goals of teaching these languages and their role in students’ future. Goals of language teaching and students’ attitudes towards the process will be related to the job opportunities available for the students on graduation. Data for the paper have been collected using questionnaires and interviews administered to students and teachers from five language departments at Khartoum University: English, French, German, Russian, and Chinese. Questionnaires and interviews on language attitude will be administered among Four-year language majors representing the four departments. The central question the paper tries to answer is whether there is a realistic match between the goals of language teaching/learning set by policy makers and students’ interests and expectations. Results are expected to contribute to the efforts made to restructure language-in-education curriculum at university level in a way that addresses the expectations of both policy makers and students. Keywords: Foreign language teaching and learning, goals, attitude.

Disposal criticality analysis methodology's principal isotope burnup credit

International Nuclear Information System (INIS)

Doering, T.W.; Thomas, D.A.

2001-01-01

This paper presents the burnup credit aspects of the United States Department of Energy Yucca Mountain Project's methodology for performing criticality analyses for commercial light-water-reactor fuel. The disposal burnup credit methodology uses a 'principal isotope' model, which takes credit for the reduced reactivity associated with the build-up of the primary principal actinides and fission products in irradiated fuel. Burnup credit is important to the disposal criticality analysis methodology and to the design of commercial fuel waste packages. The burnup credit methodology developed for disposal of irradiated commercial nuclear fuel can also be applied to storage and transportation of irradiated commercial nuclear fuel. For all applications a series of loading curves are developed using a best estimate methodology and depending on the application, an additional administrative safety margin may be applied. The burnup credit methodology better represents the 'true' reactivity of the irradiated fuel configuration, and hence the real safety margin, than do evaluations using the 'fresh fuel' assumption.

Principal Leadership Style and Teacher Commitment among a Sample of Secondary School Teachers in Barbados

Directory of Open Access Journals (Sweden)

Ian Alwyn Marshall

2015-05-01

Full Text Available In Barbados, the issue of principal leadership and teacher productivity has occupied the attention of teacher unions and educational authorities alike.  The teachers have been calling for principals to be removed while the principals have been arguing for greater autonomy to discipline teachers. This state of affairs has, understandably, adversely impacted teacher commitment levels.  In the literature there is a clear correlation between principal leadership style and teacher commitment, however, it is important to know whether or not the relationship holds true in the context of Barbadian schools. This author is of the view that if teacher commitment levels are to return to those in evidence in effective schools, then attention must be given to the way in which principals exercise their leadership functions. This study was therefore designed to examine in greater detail the relationship between principal leadership style and teacher commitment.  The author employed purposive sampling to survey a cohort of ninety (90 teachers and eleven (11 principals drawn from eleven secondary schools. Results confirmed the relationship between principal leadership style and teacher commitment, and a statistically significant difference in the level of commitment reported by teachers at newer secondary schools and teachers at older secondary schools. Results also indicated that biographical variables moderated the relationship between principal leadership style and teacher commitment. Additionally, the regression model indicated that the principal leadership style sub-variables, in combination, accounted for some variance in the commitment demonstrated by teachers.

Machine learning of frustrated classical spin models. I. Principal component analysis

Science.gov (United States)

Wang, Ce; Zhai, Hui

2017-10-01

This work aims at determining whether artificial intelligence can recognize a phase transition without prior human knowledge. If this were successful, it could be applied to, for instance, analyzing data from the quantum simulation of unsolved physical models. Toward this goal, we first need to apply the machine learning algorithm to well-understood models and see whether the outputs are consistent with our prior knowledge, which serves as the benchmark for this approach. In this work, we feed the computer data generated by the classical Monte Carlo simulation for the X Y model in frustrated triangular and union jack lattices, which has two order parameters and exhibits two phase transitions. We show that the outputs of the principal component analysis agree very well with our understanding of different orders in different phases, and the temperature dependences of the major components detect the nature and the locations of the phase transitions. Our work offers promise for using machine learning techniques to study sophisticated statistical models, and our results can be further improved by using principal component analysis with kernel tricks and the neural network method.

Kehr, Hugo M

2003-07-01

Researchers widely understand that conflicts among goals inhibit the attainment of these goals. However, this notion comes close to tautological reasoning. To avert this problem, this study examined whether preexisting goal conflict also inhibits success in newly set goals. Using the context of management training, in which managers collectively set new goals, the study variables were assessed at 3 testing periods covering 5 months. Results indicate that goal conflicts that persevere over time were associated with inhibited attainment of new goals but not with decreased subjective well-being (SWB). Goal attainment, however, was positively related to SWB. Interactions of residual changes in goal conflict and goal attainment were associated with positive affect.

Full Text Available This study involved a survey of the attitudes of Texas public school principals and certified librarians, perceptions andexperiences with regard to school library policy for media selection, and procedures for responding to complaints againstlibrary media. Analysis of the data included a methodology of mixed-methods explanatory design. Selection of the principalsand certified librarians was proportionate and stratified according to the state's 20 Education Service Centerregions. Of the 1,036 independent school districts that employed the state population of 10,014 principals and certifiedlibrarians, 275 independent school districts (26.5 percent allowed participation in the survey. Although random samplingof the state population had not been possible, the demographic and employment characteristics of the study samplewere comparable to those of the state population. Two key findings were (a that the legal opinions of principals andcertified librarians were useful predictors of their opinions of library media selection policy and complaint proceduresand (b that the principals' appreciation of selection policy and complaint procedures sometimes differed from the librarians'because of the principals' different legal perspective of library selection policy and complaint procedures.

BROOKHAVEN: Proton goal reached

On March 30 the 35-year old Alternating Gradient Synchrotron (AGS) exceeded its updated design goal of 6 x 10 13 protons per pulse (ppp), by accelerating 6.3 x 10 13 ppp, a world record intensity. This goal was set 11 years ago and achieving it called for the construction of a new booster and the reconstruction of much of the AGS. The booster was completed in 1991, and reached its design intensity of 1.5 x 10 13 ppp in 1993. The AGS reconstruction was finished in 1994, and by July of that year the AGS claimed a new US record intensity for a proton synchrotron of 4 x 10 13 ppp, using four booster pulses. Reaching the design intensity was scheduled for 1995. In 1994, the AGS had seemed to be solidly limited to 4 x 10 13 ppp, but in 1995 the operations crew, working on their own in the quiet of the owl shift, steadily improved the intensity, regularly setting new records, much to the bemusement of the machine physicists. The physicists, however, did contribute. A second harmonic radiofrequency cavity in the booster increased the radiofrequency bucket area for capture, raising the booster intensity from 1.7 to 2.1 x 10 13 ppp. In the AGS, new radiofrequency power supplies raised the available voltage from 8 to 13 kV, greatly enhancing the beam loading capabilities of the system. A powerful new transverse damping system successfully controlled instabilities that otherwise would have destroyed the beam in less than a millisecond. Also in the AGS, 35th harmonic octupole resonances were found

Application of probabilistic safety goals to regulation of nuclear power plants in Canada

Energy Technology Data Exchange (ETDEWEB)

Rzentkowski, G.; Akl, Y.; Yalaoui, S. [Canadian Nuclear Safety Commission, Ottawa, Ontario (Canada)

2013-07-01

In the Canadian nuclear regulatory framework, Safety Goals are formulated in addition to the deterministic design requirements and the dose acceptance criteria so that risk to the public that originates from accidents outside the design basis is considered. In principle, application of the Safety Goals ensures that the likelihood of accidents with serious radiological consequences is extremely low, and the potential radiological consequences from severe accidents are limited as far as practicable. Effectively, the Safety Goals extend the plant design envelope to include not only the capabilities of the plant to successfully cope with various plant states, but also practical measures to halt the progression of severe accidents. This paper describes the general approach to the development of the Safety Goals and their application to the existing nuclear power plants in Canada. This general approach is consistent with the currently accepted international practice and Canadian regulatory experience. The results of probabilistic safety assessments indicate that the Safety Goals meet or exceed international safety objectives due to effective implementation of the defence-in-depth principle in the reactor design and plant operation. At the same time, the application of the Safety Goals reveal that practicable measures exist to further enhance the overall level of reactor safety by focusing on severe accident prevention and mitigation. These measures are being currently implemented through refurbishment projects and feedback on operating experience. (author)

Design of a fault diagnosis system for next generation nuclear power plants

International Nuclear Information System (INIS)

Zhao, K.; Upadhyaya, B.R.; Wood, R.T.

2004-01-01

A new design approach for fault diagnosis is developed for next generation nuclear power plants. In the nuclear reactor design phase, data reconciliation is used as an efficient tool to determine the measurement requirements to achieve the specified goal of fault diagnosis. In the reactor operation phase, the plant measurements are collected to estimate uncertain model parameters so that a high fidelity model can be obtained for fault diagnosis. The proposed algorithm of fault detection and isolation is able to combine the strength of first principle model based fault diagnosis and the historical data based fault diagnosis. Principal component analysis on the reconciled data is used to develop a statistical model for fault detection. The updating of the principal component model based on the most recent reconciled data is a locally linearized model around the current plant measurements, so that it is applicable to any generic nonlinear systems. The sensor fault diagnosis and process fault diagnosis are decoupled through considering the process fault diagnosis as a parameter estimation problem. The developed approach has been applied to the IRIS helical coil steam generator system to monitor the operational performance of individual steam generators. This approach is general enough to design fault diagnosis systems for the next generation nuclear power plants. (authors)

Teachers' goal orientations: Effects on classroom goal structures and emotions.

Science.gov (United States)

Wang, Hui; Hall, Nathan C; Goetz, Thomas; Frenzel, Anne C

2017-03-01

Prior research has shown teachers' goal orientations to influence classroom goal structures (Retelsdorf et al., 2010, Learning and Instruction, 20, 30) and to also impact their emotions (Schutz et al., 2007, Emotion in education, Academic Press, Amsterdam, the Netherlands). However, empirical research evaluating possible causal ordering and mediation effects involving these variables in teachers is presently lacking. The present 6-month longitudinal study investigated the relations between varied motivational, behavioural, and emotional variables in practising teachers. More specifically, this study examined the reciprocal, longitudinal relations between teachers' achievement goals, classroom goal structures, and teaching-related emotions, as well as cumulative mediational models in which observed causal relations were evaluated. Participants were 495 practising teachers from Canada (86% female, M = 42 years). Teachers completed a web-based questionnaire at two time points assessing their instructional goals, perceived classroom goal structures, achievement emotions, and demographic items. Results from cross-lagged analyses and structural equation modelling showed teachers' achievement goals to predict their perceived classroom goal structures that, in turn, predicted their teaching-related emotions. The present results inform both Butler's (2012, Journal of Educational Psychology, 104, 726) theory on teachers' achievement goals and Frenzel's (2014, International handbook of emotions in education, Routledge, New York, NY) model of teachers' emotions in showing teachers' instructional goals to both directly predict their teaching-related emotions, as well as indirectly through the mediating effects of classroom goal structures. © 2016 The British Psychological Society.

Cecchini Estrada, José A; González González-Mesa, Carmen; Méndez-Giménez, Antonio; Fernández-Río, Javier

2011-02-01

This study examined the relationship between achievement and social goals, and explored how both goals affect students' level of informed self-determination in Physical Education. Participants were 395 high school students. Three scales were used to assess achievement, social goals, and motivation. Several hierarchical regression analyses revealed that mastery-approach goals were the greatest contributors to the individuals' levels of self-determination. Achievement and social goals were found to be separate predictors of students' levels of self-determination, and this highlights the importance of separating mastery and performance goals into avoidance and approach profiles. Girls reported significantly higher values than boys on responsibility, relationship, and mastery-avoidance goals, whereas boys scored higher on performance-approach goals. Researchers could use achievement and social goals to study students' motivation and achievement in Physical Education settings.

Quantitative safety goals for the regulatory process

International Nuclear Information System (INIS)

Joksimovic, V.; O'Donnell, L.F.

1981-01-01

The paper offers a brief summary of the current regulatory background in the USA, emphasizing nuclear, related to the establishment of quantitative safety goals as a way to respond to the key issue of 'how safe is safe enough'. General Atomic has taken a leading role in advocating the use of probabilistic risk assessment techniques in the regulatory process. This has led to understanding of the importance of quantitative safety goals. The approach developed by GA is discussed in the paper. It is centred around definition of quantitative safety regions. The regions were termed: design basis, safety margin or design capability and safety research. The design basis region is bounded by the frequency of 10 -4 /reactor-year and consequences of no identifiable public injury. 10 -4 /reactor-year is associated with the total projected lifetime of a commercial US nuclear power programme. Events which have a 50% chance of happening are included in the design basis region. In the safety margin region, which extends below the design basis region, protection is provided against some events whose probability of not happening during the expected course of the US nuclear power programme is within the range of 50 to 90%. Setting the lower mean frequency to this region of 10 -5 /reactor-year is equivalent to offering 90% assurance that an accident of given severity will not happen. Rare events with a mean frequency below 10 -5 can be predicted to occur. However, accidents predicted to have a probability of less than 10 -6 are 99% certain not to happen at all, and are thus not anticipated to affect public health and safety. The area between 10 -5 and 10 -6 defines the frequency portion of the safety research region. Safety goals associated with individual risk to a maximum-exposed member of public, general societal risk and property risk are proposed in the paper

[Perceptions of classroom goal structures, personal achievement goal orientations, and learning strategies].

Science.gov (United States)

Miki, Kaori; Yamauchi, Hirotsugu

2005-08-01

We examined the relations among students' perceptions of classroom goal structures (mastery and performance goal structures), students' achievement goal orientations (mastery, performance, and work-avoidance goals), and learning strategies (deep processing, surface processing and self-handicapping strategies). Participants were 323 5th and 6th grade students in elementary schools. The results from structural equation modeling indicated that perceptions of classroom mastery goal structures were associated with students' mastery goal orientations, which were in turn related positively to the deep processing strategies and academic achievement. Perceptions of classroom performance goal stractures proved associated with work avoidance-goal orientations, which were positively related to the surface processing and self-handicapping strategies. Two types of goal structures had a positive relation with students' performance goal orientations, which had significant positive effects on academic achievement. The results of this study suggest that elementary school students' perceptions of mastery goal structures are related to adaptive patterns of learning more than perceptions of performance goal structures are. The role of perceptions of classroom goal structure in promoting students' goal orientations and learning strategies is discussed.

We describe a reduction process for symplectic principal R-bundles in the presence of a momentum map. These types of structures play an important role in the geometric formulation of non-autonomous Hamiltonian systems. We apply this procedure to the standard symplectic principal R-bundle associated with a fibration π:M→R. Moreover, we show a reduction process for non-autonomous Hamiltonian systems on symplectic principal R-bundles. We apply these reduction processes to several examples. (paper)

Meeting performance goals by the use of experience data

International Nuclear Information System (INIS)

Salmon, M.W.; Kennedy, R.P.

1993-01-01

DOE Order 5480.28 requires that structures, systems and components (SSCs) be designed and constructed to withstand the effects of natural phenomena hazards. For SSCs to be acceptable, it must be demonstrated that there is a sufficiently low probability of failure of those SSCs consistent with established performance goals. For new design, NPH loads are taken from probabilistic hazard assessments and coupled with response and evaluation methods to control the levels of conservatism required to achieve performance goals. For components qualified by test, performance goals are achieved by specifying a test response spectrum that envelops a required response spectrum coupled with minimal acceptance standards. DOE Standard 1020-92 adapts both of these approaches to ensure that the required performance goals are met for new installations. For existing installations these approaches are generally not applicable. There is a need for a simple approach for use in verifying the performance of existing equipment subject to seismic hazards. The USNRC has adapted such an approach for the resolution of USI A-46 in the Generic Implementation Procedure (GIP). A simple set of screening rules, keyed to a generic bounding spectrum forms the basis of the USNRC approach. A similar approach is being adapted for use in the DOE. The DOE approach, however, must also ensure that appropriate performance goals are met when the general screens are met. This paper summarizes research to date on the topic of meeting performance goals by the use of experience data. The paper presents a review of the background material, a summary of the requirements for existing components, a summary of the approach used in establishing the performance goals associated with experience data approaches, and a summary of results to date. Simplified criteria are proposed

Update of ZTH physics and design issues and physics goals of ZTH and role in the Fusion Program

International Nuclear Information System (INIS)

DiMarco, J.N.

1990-01-01

The ZTH construction program is scheduled for completion in December of 1992. Some design features are still amenable to changes directed by new physics or computational information. Numerical results for the ZTH tapered poloidal field gap show that a relatively simple linear taper results in substantial reduction in field error. This design is simpler to manufacture compared with the compound curve predicted by analytical calculations. Also, ongoing analysis of ZT-40M data indicates that the fluctuation levels of magnetic fields and x-rays at high θ (1.7), can be reduced to the fluctuation levels at ''standard'' operational θ (1.4) by changing the winding configuration of the toroidal field (TF) coils. The effect is thought to depend on the shell-like action of the TF coils when they consist of many turns in parallel. Magnetic-field effects, such as field errors, at the unshielded toroidal-field butt-joint gap in the shell can be reduced by this effective external shell. Design implications for installing a second low-current TF coil on ZTH are presented. ZTH has the capability of operating at 4 MA with the addition of power supplies. The projected parameters of ZTH are discussed in the context of various conceptual design. The sensitivity of the conceptual design to the physics results from machines like RFX and ZTH is reviewed. It is shown that the 4 MA ZTH physics results will make a significant advance for the RFP program toward the programmatic RFP fusion goals. Finally, the influence of RFP and tokamak physics on the conceptual design of high mass-power-density (MPD) fusion reactors is investigated through the TITAN and ARIES studies. The confinement characteristics required of these conceptual designs are compared; physics issues are identified that are required to bring the MPD and fusion-power-core of the tokamak designs into coincidence with the RFP designs

Medical and business are one of the most popular majors among students, and both fields require intensive training to reach certain level of expertise. During the development of professionalism, goal can become a crucial role in psychological impetus. The purpose of this study is to compare goal contents, goal characteristics, and effect of goal characteristics on student's major satisfaction between medical and business. A total of 193 undergraduate students (97 medical students, 96 business students) answered survey questions including goal contents, goal characteristics (goal autonomy, goal attainability, social value of goal) and satisfaction on their majors. Qualitative analysis of goal contents and quantitative analysis of goal characteristics, and their effects on student major satisfaction were performed. Goal content analysis showed percentage of social concern goal was higher in medical students (25.8%) than business students (6.3%), whereas percentage of wealth goal was higher business students (24.0%) than medical students (3.1%). Among goal characteristics, goal attainability and social value of goal were higher in medical students than business students. In both groups, social value of goal was significantly predict major satisfaction. Goal contents and goal characteristics are different between medical and business students. Curriculum and educational interventions that concerning students' goal and developing programs to enhance students' social value of goal is necessary.

Dauwerse, L; Abma, T A; Molewijk, B; Widdershoven, G

2013-12-01

In previous literature, ethicists mention several goals of Clinical Ethics Support (CES). It is unknown what key persons in healthcare institutions see as main--and sub-goals of CES. This article presents the goals of CES as perceived by board members and members of ethics support staff. This is part of a Dutch national research using a mixed methods design with questionnaires, focus groups and interviews. Quantitative and qualitative data were analyzed and combined in an iterative process. Four main clusters of goals were found: 1) encouraging an ethical climate, 2) fostering an accountable and transparent organization, 3) developing professionalism and a final goal, overarching the previous three, 4) good care. Most important sub-goals of CES were: attention for ethical issues, raising awareness of ethical issues, fostering ethical reflection and supporting employees. The article ends with a discussion on the desirability to further operationalize the general goal of good care, the context-boundedness of our findings and the need to relate goals of CES to the features of organizational cultures to further improve the integration of CES in healthcare institutions.

A novel procedure for parathion hapten design is described. The optimal antigen for parathion was selected after molecular modeling studies of six types of potentially immunizing haptens with the aim to identify the best mimicking target analyte. Heterologous competitive indirect enzyme-linked immunosorbent assay (ELISA) was developed after screening a battery of competitors as coating antigens. The relationship between the heterology degree of the competitor and the resulting immunoassay detectability was investigated according to the electronic similarities of the competitor haptens and the target analyte. Molecular modeling and principal component analysis were performed to understand the electronic distribution and steric parameters of the haptens at their minimum energetic levels. The results suggested that the competitors should have a high heterology to produce assays with good detectability values. An indirect competitive ELISA was finally selected for further investigation. The immunoassay had an IC{sub 50} value of 4.79 ng mL{sup -1} and a limit of detection of 0.31 ng mL{sup -1}. There was little or no cross-reactivity to similar compounds tested except for the insecticide parathion-methyl, which showed a cross-reactivity of 7.8%.

2017-02-01

Full Text Available This research work is an exploration of causality connection of learning styles to mathematics achievement goals. The objectives of the study are as follows: (1 to identify the mathematics achievement goal of students when grouped according to preferred learning style (2 to identify the learning style of students when grouped according to preferred mathematics achievement goal and (3 to determine if there is a significant difference in each mathematics achievement goal when grouped according to learning style. The researcher used explanatory cross-sectional design. The Revised Achievement Goal Questionnaire and Kolb’s Learning Style Inventory 3.1 were utilized to collect data. Results show that respondents hold mastery-approach achievement goals regardless of learning styles. Also, students with approach type of mathematics achievement goals hold assimilative learning style which operates on reflective observation and abstract conceptualization; and students with avoidance type of mathematics achievement goals hold accommodative learning style which operates on active experimentation and concrete experimentation. Furthermore, findings show that there is no significant difference in the mathematics achievement goals based on learning style. Exploratory research is recommended to understand why students with approach type of mathematics achievement goals hold assimilative learning style and why students with avoidance type of mathematics achievement goals hold accommodative learning style.

Seismic analysis - what goal

International Nuclear Information System (INIS)

Tagart, S.W.

1978-01-01

The seismic analysis of nuclear components is characterized today by extensive engineering computer calculations in order to satisfy both the component standard codes such as ASME III as well as federal regulations and guides. The current nuclear siesmic design procedure has envolved in a fragmented fashion and continues to change its elements as improved technology leads to changing standards and guides. The dominant trend is a monotonic increase in the overall conservation with time causing a similar trend in costs of nuclear power plants. Ironically the improvements in the state of art are feeding a process which is eroding the very incentives that attracted us to nuclear power in the first place. This paper examines the cause of this process and suggests that what is needed is a realistic goal which appropriately addresses the overall uncertainty of the seismic design process. (Auth.)

Principal minors and rhombus tilings

International Nuclear Information System (INIS)

Kenyon, Richard; Pemantle, Robin

2014-01-01

The algebraic relations between the principal minors of a generic n × n matrix are somewhat mysterious, see e.g. Lin and Sturmfels (2009 J. Algebra 322 4121–31). We show, however, that by adding in certain almost principal minors, the ideal of relations is generated by translations of a single relation, the so-called hexahedron relation, which is a composition of six cluster mutations. We give in particular a Laurent-polynomial parameterization of the space of n × n matrices, whose parameters consist of certain principal and almost principal minors. The parameters naturally live on vertices and faces of the tiles in a rhombus tiling of a convex 2n-gon. A matrix is associated to an equivalence class of tilings, all related to each other by Yang–Baxter-like transformations. By specializing the initial data we can similarly parameterize the space of Hermitian symmetric matrices over R,C or H the quaternions. Moreover by further specialization we can parametrize the space of positive definite matrices over these rings. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Cluster algebras mathematical physics’. (paper)

Modeling Coherent Strategies for the Sustainable Development Goals

Walsh, B.; Obersteiner, M.; Herrero, M.; Riahi, K.; Fritz, S.; van Vuuren, D.; Havlik, P.

2016-12-01

The Sustainable Development Goals (SDGs) call for a comprehensive new approach to development rooted in planetary boundaries, equity and inclusivity. Societies have largely responded to this call with siloed strategies capable of making progress on selected subsets of these goals. However, agendas crafted specifically to alleviate poverty, hunger, deforestation, biodiversity loss, or other ills may doom the SDG agenda, as policies and strategies designed to accomplish one or several goals can impede and in some cases reverse progress toward others at national, regional, and global levels. We adopt a comprehensive modeling approach to understand the basis for tradeoffs among environmental conservation initiatives (goals 13-15) and food prices (goal 2). We show that such tradeoffs are manifestations of policy-driven pressure in land (i.e. agricultural and environmental) systems. By reducing total land system pressure, Sustainable Consumption and Production (SCP, goal 12) policies minimize tradeoffs and should therefore be regarded as necessary conditions for achieving multiple SDGs. SDG strategies constructed around SCP policies escape problem-shifting, which has long placed global development and conservation agendas at odds. We expect that this and future systems analyses will allow policymakers to negotiate tradeoffs and exploit synergies as they assemble sustainable development strategies equal in scope to the ambition of the SDGs.

2016-10-01

The purposes of this study were to examine the effects of varying levels of goals on increasing daily steps and the frequency of goal achievement among middle-aged adults. Ninety-six adults participated in a randomised control study. Participants were randomly assigned to five different step goal groups: (1) Easy (n = 19), (2) Medium (n = 19), (3) Difficult (n = 19), (4) Do-your-best (n = 19), and (5) No goal (n = 20) based on previous research. The participants wore a pedometer and were asked to reach a pre-established goal during the experimental period. In order to examine the effectiveness of the goal difficulty, (a) an average number of steps taken by different goal conditions and (b) the number of days meeting the assigned goal were tested. A one-way ANCOVA revealed significant step count differences among goal groups. Post hoc analyses indicated that the change in step count in both the Medium and Difficult goal groups was significantly greater than the remaining groups. However, there was no significant difference between the medium and difficult goal conditions. In addition, a one-way ANOVA indicated that there were no significant differences in the frequency of goal achievement among the Easy, Medium, and Difficult goal groups. Results suggest that when promoting physical activity through increasing step counts, researchers and clinicians should design goals that are specific and challenging.

Rewards: A predictor of well-being and service quality of school principals in the North-West province

2016-08-01

Full Text Available Orientation: School principals have an important role to play in the quality of service delivery in schools. Evidence suggests that school principals are generally poorly compensated, which has an adverse impact on their well-being and subsequent service quality orientation. Research purpose: This study investigated whether rewards are a predictor of well-being and service orientation of school principals in the North-West province. Motivation for the study: Effective school principals are fundamental to the success of any school, which necessitates the establishment of an effective reward and remuneration system. Research design, approach and method: Quantitative research was carried out among school principals (N = 155 in four districts of the North-West province. The Total Rewards Scale, Maslach’s Burnout Inventory – General Survey, the Utrecht Work Engagement Scale and the SERVQUAL measure were administered among the principals. Main findings: The results showed that rewards are a significant predictor of the well-being and service quality of school principals. The results further showed that burnout significantly reduces the service quality of school principals. No significant relationships were found between work engagement and the service quality of school principals.

Self-regulation of unattainable goals in suicide attempters: the relationship between goal disengagement, goal reengagement and suicidal ideation.

LENUS (Irish Health Repository)

O'Connor, Rory C

2009-02-01

There is growing interest in models of adaptive self-regulation. Recent research suggests that goal disengagement and goal reengagement (i.e., goal adjustment) are implicated in the self-regulation of emotion. This study extends the self-regulation research to investigate the utility of goal adjustment in understanding suicidal risk. To this end, two hundred adults hospitalised following a suicidal episode completed a range of clinical and psychological measures in hospital and were followed up approximately 2.5 months after discharge (Time 2). Hierarchical regression analyses showed that goal reengagement predicted suicidal ideation at Time 2. In addition, the lack of goal reengagement was especially pernicious when reported concomitantly with high disengagement. These predictive effects were independent of baseline mood, attempt status and suicidal intent. The theoretical and clinical implications are discussed.

Salud, equidad y los objetivos de desarrollo del milenio Health, equity, and the Millennium Development Goals

Cristina Torres

2004-06-01

Full Text Available In September 2000 representatives of 189 countries met for the Millennium Summit, which the United Nations convened in New York City, and adopted the declaration that provided the basis for formulating the Millennium Development Goals (MDGs. The eight goals are part of a long series of initiatives that governments, the United Nations system, and international financial institutions have undertaken to reduce world poverty. Three of the eight goals deal with health, so the health sector will be responsible for implementing, monitoring, and evaluating measures proposed to meet targets that have been formulated: to reduce by two-thirds the mortality rate in children under 5 years of age between 1990 and 2015; to reduce by three-quarters the maternal mortality rate between 1990 and 2015; and to halt and begin to reverse the spread of HIV/AIDS by the year 2015, as well as to halt and begin to reverse the incidence of malaria, tuberculosis, and other major diseases. The health sector must also work with other parties to achieve targets connected with two other of the goals: to improve access to affordable essential drugs, and to reduce the proportion of persons who do not have safe drinking water. Adopting a strategy focused on the most vulnerable groups-ones concentrated in locations and populations with the greatest social exclusion-would make possible the largest total reduction in deaths among children, thus reaching the proposed target as well as producing greater equity. In the Region of the Americas the principal challenges in meeting the MDGs are: improving and harmonizing health information systems; designing health programs related to the MDGs that bring together the set of services and interventions that have the greatest impact, according to the special characteristics of the populations who are intended to be the beneficiaries; strengthening the political will to support the MDGs; and guaranteeing funding for the measures undertaken to

Methods and strategies for future reactor safety goals

Science.gov (United States)

Arndt, Steven Andrew

-informed analyses and discussions. This dissertation examines potential approaches to updating the safety goals that include the establishment of new quantitative safety goal associated with the comparative risk of generating electricity by viable competing technologies and modifications of the goals to account for multi-plant reactor sites, and issues associated with the use of safety goals in both initial licensing and operational decision making. This research develops a new quantitative health objective that uses a comparable benefit risk metric based on the life-cycle risk of the construction, operation and decommissioning of a comparable non-nuclear electric generation facility, as well as the risks associated with mining and transportation. This dissertation also evaluates the effects of using various methods for aggregating site risk as a safety metric, as opposed to using single plant safety goals. Additionally, a number of important assumptions inherent in the current safety goals, including the effect of other potential negative societal effects such as the generation of greenhouse gases (e.g., carbon dioxide) have on the risk of electric power production and their effects on the setting of safety goals, is explored. Finally, the role risk perception should play in establishing safety goals has been explored. To complete this evaluation, a new method to analytically compare alternative technologies of generating electricity was developed, including development of a new way to evaluate risk perception, and a new method was developed for evaluating the risk at multiple units on a single site. To test these modifications to the safety goals a number of possible reactor designs and configurations were evaluated using these new proposed safety goals to determine the goals' usefulness and utility. The results of the analysis showed that the modifications provide measures that more closely evaluate the potential risk to the public from the operation of nuclear power plants than

Soft X-ray spectrometer design for warm dense plasma measurements on DARHT Axis-I

Ramey, Nicholas Bryan [Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Perry, John Oliver [Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Coleman, Joshua Eugene [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

2017-07-11

A preliminary design study is being performed on a soft X-ray spectrometer to measure K-shell spectra emitted by a warm dense plasma generated on Axis-I of the Dual-Axis Radiographic Hydrodynamic Testing (DARHT) facility at Los Alamos National Laboratory. The 100-ns-long intense, relativistic electron pulse with a beam current of 1.7 kA and energy of 19.8 MeV deposits energy into a thin metal foil heating it to a warm dense plasma. The collisional ionization of the target by the electron beam produces an anisotropic angular distribution of K-shell radiation and a continuum of both scattered electrons and Bremsstrahlung up to the beam energy of 19.8 MeV. The principal goal of this project is to characterize these angular distributions to determine the optimal location to deploy the soft X-ray spectrometer. In addition, a proof-of-principle design will be presented. The ultimate goal of the spectrometer is to obtain measurements of the plasma temperature and density to benchmark equation-of-state models of the warm dense matter regime.

Latitude-Time Total Electron Content Anomalies as Precursors to Japan's Large Earthquakes Associated with Principal Component Analysis

Directory of Open Access Journals (Sweden)

Jyh-Woei Lin

2011-01-01

Full Text Available The goal of this study is to determine whether principal component analysis (PCA can be used to process latitude-time ionospheric TEC data on a monthly basis to identify earthquake associated TEC anomalies. PCA is applied to latitude-time (mean-of-a-month ionospheric total electron content (TEC records collected from the Japan GEONET network to detect TEC anomalies associated with 18 earthquakes in Japan (M≥6.0 from 2000 to 2005. According to the results, PCA was able to discriminate clear TEC anomalies in the months when all 18 earthquakes occurred. After reviewing months when no M≥6.0 earthquakes occurred but geomagnetic storm activity was present, it is possible that the maximal principal eigenvalues PCA returned for these 18 earthquakes indicate earthquake associated TEC anomalies. Previously PCA has been used to discriminate earthquake-associated TEC anomalies recognized by other researchers, who found that statistical association between large earthquakes and TEC anomalies could be established in the 5 days before earthquake nucleation; however, since PCA uses the characteristics of principal eigenvalues to determine earthquake related TEC anomalies, it is possible to show that such anomalies existed earlier than this 5-day statistical window.

Principal-vector-directed fringe-tracking technique.

Science.gov (United States)

Zhang, Zhihui; Guo, Hongwei

2014-11-01

Fringe tracking is one of the most straightforward techniques for analyzing a single fringe pattern. This work presents a principal-vector-directed fringe-tracking technique. It uses Gaussian derivatives for estimating fringe gradients and uses hysteresis thresholding for segmenting singular points, thus improving the principal component analysis method. Using it allows us to estimate the principal vectors of fringes from a pattern with high noise. The fringe-tracking procedure is directed by these principal vectors, so that erroneous results induced by noise and other error-inducing factors are avoided. At the same time, the singular point regions of the fringe pattern are identified automatically. Using them allows us to determine paths through which the "seed" point for each fringe skeleton is easy to find, thus alleviating the computational burden in processing the fringe pattern. The results of a numerical simulation and experiment demonstrate this method to be valid.

To determine the feasibility, the cluster design effect and the variance and minimal clinical importance difference in the primary outcome in a pilot study of a structured approach to goal-setting. A cluster randomized controlled trial. Inpatient rehabilitation facilities. People who were admitted to inpatient rehabilitation following stroke who had sufficient cognition to engage in structured goal-setting and complete the primary outcome measure. Structured goal elicitation using the Canadian Occupational Performance Measure. Quality of life at 12 weeks using the Schedule for Individualised Quality of Life (SEIQOL-DW), Functional Independence Measure, Short Form 36 and Patient Perception of Rehabilitation (measuring satisfaction with rehabilitation). Assessors were blinded to the intervention. Four rehabilitation services and 41 patients were randomized. We found high values of the intraclass correlation for the outcome measures (ranging from 0.03 to 0.40) and high variance of the SEIQOL-DW (SD 19.6) in relation to the minimally importance difference of 2.1, leading to impractically large sample size requirements for a cluster randomized design. A cluster randomized design is not a practical means of avoiding contamination effects in studies of inpatient rehabilitation goal-setting. Other techniques for coping with contamination effects are necessary.

Reconfigurable manufacturing systems: Principles, design, and future trends

Science.gov (United States)

Koren, Yoram; Gu, Xi; Guo, Weihong

2018-06-01

Reconfigurable manufacturing systems (RMSs), which possess the advantages of both dedicated serial lines and flexible manufacturing systems, were introduced in the mid-1990s to address the challenges initiated by globalization. The principal goal of an RMS is to enhance the responsiveness of manufacturing systems to unforeseen changes in product demand. RMSs are costeffective because they boost productivity, and increase the lifetime of the manufacturing system. Because of the many streams in which a product may be produced on an RMS, maintaining product precision in an RMS is a challenge. But the experience with RMS in the last 20 years indicates that product quality can be definitely maintained by inserting in-line inspection stations. In this paper, we formulate the design and operational principles for RMSs, and provide a state-of-the-art review of the design and operations methodologies of RMSs according to these principles. Finally, we propose future research directions, and deliberate on how recent intelligent manufacturing technologies may advance the design and operations of RMSs.

2010-08-01

Work motivation, mental well-being and competencies of self-regulation are linked to successful job-related reintegration after rehabilitation. Based on the Diagnostical Instrument to assess Work motivation (Diagnostikinstrument für Arbeitsmotivation DIAMO) and existing training programs, a new group intervention, the goal analysis and goal operationalization, was developed and evaluated. The objective of this intervention, designed for participants of a rehabilitation program was to enhance work motivation and volitional control processes (self-regulation and self-control), to encourage job-related goal orientation and to thereby increase the probability of goal achievement. In a quasi-experimental longitudinal design 207 patients (111 experimental group/96 control group) were tested. The experimental group took part in the job-related training (ZAZO) in addition to the usual rehabilitation. The evaluation was conducted through various scales at t0 (beginning) and t1 (end of the training). Scales for the measurement of work motivation, mental well-being, status of rehabilitation, competencies of self-regulation and the subjective prognosis of the ability to work were used. As direct effects of the training an enhancement of work motivation and of an improved subjective prognosis of the ability to work were expected. Accordingly, a positive influence on the subjective well-being as indirect effects, were anticipated in the long run, the experimental group should also show an enhanced job-related reintegration. Participants of the experimental group showed significantly higher values on particular scales of the Diagnostical Instrument of Work motivation as opposed to the control group (curiosity motive, attitudes to work and contact motive). Most notably, significant interactional effects could be found on the scale for the subjective prognosis of the ability to work, which is a highly reliable instrument and important predictor for prospective job

Kolesov, V. I.; Danilov, O. F.; Petrov, A. I.

2017-10-01

Road traffic safety (RTS) management is inherently a branch of cybernetics and therefore requires clear formalization of the task. The paper aims at identification of the specific features of goal setting in RTS management under the system approach. The paper presents the results of cybernetic modeling of the cause-to-effect mechanism of a road traffic accident (RTA); in here, the mechanism itself is viewed as a complex system. A designed management goal function is focused on minimizing the difficulty in achieving the target goal. Optimization of the target goal has been performed using the Lagrange principle. The created working algorithms have passed the soft testing. The key role of the obtained solution in the tactical and strategic RTS management is considered. The dynamics of the management effectiveness indicator has been analyzed based on the ten-year statistics for Russia.

Can motto-goals outperform learning and performance goals? Influence of goal setting on performance and affect in a complex problem solving task

Directory of Open Access Journals (Sweden)

Miriam S. Rohe

2016-09-01

Full Text Available In this paper, we bring together research on complex problem solving with that on motivational psychology about goal setting. Complex problems require motivational effort because of their inherent difficulties. Goal Setting Theory has shown with simple tasks that high, specific performance goals lead to better performance outcome than do-your-best goals. However, in complex tasks, learning goals have proven more effective than performance goals. Based on the Zurich Resource Model (Storch & Krause, 2014, so-called motto-goals (e.g., "I breathe happiness" should activate a person’s resources through positive affect. It was found that motto-goals are effective with unpleasant duties. Therefore, we tested the hypothesis that motto-goals outperform learning and performance goals in the case of complex problems. A total of N = 123 subjects participated in the experiment. In dependence of their goal condition, subjects developed a personal motto, learning, or performance goal. This goal was adapted for the computer-simulated complex scenario Tailorshop, where subjects worked as managers in a small fictional company. Other than expected, there was no main effect of goal condition for the management performance. As hypothesized, motto goals led to higher positive and lower negative affect than the other two goal types. Even though positive affect decreased and negative affect increased in all three groups during Tailorshop completion, participants with motto goals reported the lowest rates of negative affect over time. Exploratory analyses investigated the role of affect in complex problem solving via mediational analyses and the influence of goal type on perceived goal attainment.

Goal-Function Tree Modeling for Systems Engineering and Fault Management

Science.gov (United States)

Johnson, Stephen B.; Breckenridge, Jonathan T.

2013-01-01

The draft NASA Fault Management (FM) Handbook (2012) states that Fault Management (FM) is a "part of systems engineering", and that it "demands a system-level perspective" (NASAHDBK- 1002, 7). What, exactly, is the relationship between systems engineering and FM? To NASA, systems engineering (SE) is "the art and science of developing an operable system capable of meeting requirements within often opposed constraints" (NASA/SP-2007-6105, 3). Systems engineering starts with the elucidation and development of requirements, which set the goals that the system is to achieve. To achieve these goals, the systems engineer typically defines functions, and the functions in turn are the basis for design trades to determine the best means to perform the functions. System Health Management (SHM), by contrast, defines "the capabilities of a system that preserve the system's ability to function as intended" (Johnson et al., 2011, 3). Fault Management, in turn, is the operational subset of SHM, which detects current or future failures, and takes operational measures to prevent or respond to these failures. Failure, in turn, is the "unacceptable performance of intended function." (Johnson 2011, 605) Thus the relationship of SE to FM is that SE defines the functions and the design to perform those functions to meet system goals and requirements, while FM detects the inability to perform those functions and takes action. SHM and FM are in essence "the dark side" of SE. For every function to be performed (SE), there is the possibility that it is not successfully performed (SHM); FM defines the means to operationally detect and respond to this lack of success. We can also describe this in terms of goals: for every goal to be achieved, there is the possibility that it is not achieved; FM defines the means to operationally detect and respond to this inability to achieve the goal. This brief description of relationships between SE, SHM, and FM provide hints to a modeling approach to

An Approach to Integrating Tactical Decision-Making in Industrial Maintenance Balance Scorecards Using Principal Components Analysis and Machine Learning

Directory of Open Access Journals (Sweden)

Néstor Rodríguez-Padial

2017-01-01

Full Text Available The uncertainty of demand has led production systems to become increasingly complex; this can affect the availability of the machines and thus their maintenance. Therefore, it is necessary to adequately manage the information that facilitates decision-making. This paper presents a system for making decisions related to the design of customized maintenance plans in a production plant. This paper addresses this tactical goal and aims to provide greater knowledge and better predictions by projecting reliable behavior in the medium-term, integrating this new functionality into classic Balance Scorecards, and making it possible to extend their current measuring function to a new aptitude: predicting evolution based on historical data. In the proposed Custom Balance Scorecard design, an exploratory data phase is integrated with another analysis and prediction phase using Principal Component Analysis algorithms and Machine Learning that uses Artificial Neural Network algorithms. This new extension allows better control over the maintenance function of an industrial plant in the medium-term with a yearly horizon taken over monthly intervals which allows the measurement of the indicators of strategic productive areas and the discovery of hidden behavior patterns in work orders. In addition, this extension enables the prediction of indicator outcomes such as overall equipment efficiency and mean time to failure.

Airborne electromagnetic data levelling using principal component analysis based on flight line difference

Science.gov (United States)

Zhang, Qiong; Peng, Cong; Lu, Yiming; Wang, Hao; Zhu, Kaiguang

2018-04-01

A novel technique is developed to level airborne geophysical data using principal component analysis based on flight line difference. In the paper, flight line difference is introduced to enhance the features of levelling error for airborne electromagnetic (AEM) data and improve the correlation between pseudo tie lines. Thus we conduct levelling to the flight line difference data instead of to the original AEM data directly. Pseudo tie lines are selected distributively cross profile direction, avoiding the anomalous regions. Since the levelling errors of selective pseudo tie lines show high correlations, principal component analysis is applied to extract the local levelling errors by low-order principal components reconstruction. Furthermore, we can obtain the levelling errors of original AEM data through inverse difference after spatial interpolation. This levelling method does not need to fly tie lines and design the levelling fitting function. The effectiveness of this method is demonstrated by the levelling results of survey data, comparing with the results from tie-line levelling and flight-line correlation levelling.

Predicting precompetitive state anxiety: using the 2 x 2 achievement goal framework.

Science.gov (United States)

Li, Chiung-Huang

2013-10-01

The goal was to examine the predictiveness of achievement goals for self-confidence, cognitive anxiety, and somatic anxiety using a prospective design. 160 high school athletes completed the 2 x 2 Achievement Goals Questionnaire for Sport after daily practice and the Revised Competitive State Anxiety Inventory-2 before an official competition. Using hierarchical regression analyses, mastery-approach goals were found as positive predictors of self-confidence and negative predictors of cognitive and somatic anxiety. In contrast, performance- and mastery-avoidance goals positively predicted cognitive and somatic anxiety. Also, performance-avoidance goals negatively predicted self-confidence. Generally, athletes who pursued task mastery and improvement of competence were less physically and cognitively anxious and more self-confident. However, athletes felt tense, worried, and had lower confidence when they endorsed avoidance forms of achievement goals.

Designing an electricity tax system in presence of international regulations and multiple public goals: An empirical assessment

International Nuclear Information System (INIS)

Bjertnaes, Geir H.; Faehn, Taran; Aasness, Jorgen

2008-01-01

The European competition rules restrict governments' opportunity to differentiate terms of energy accessibility among firms and industries. This easily runs counter with regional and industrial goals of national energy policies. Norway levies a tax on use of electricity, but exempts main industrial usages. This analysis assesses alternative, internationally legal, designs of the system in terms of their effects on efficiency and distribution, including industrial objectives. Among the reforms we explore, removing the exemptions would be the most effective way of raising revenue, but it would be politically costly by deteriorating the competitiveness of today's favoured industries. An entire abolishment of the electricity tax, and replacing revenue by increased VAT, would generate a more equal distribution of standard of living and, at the same time, avoid the trade-off between efficiency and competitiveness

Bleier, Joshua I S; Kann, Brian

2013-12-01

The development of an academic surgical career can be an overwhelming prospect, and one that is not intuitive. Establishing a structured plan and support structure is critical to success. Starting a successful academic surgical career begins with defining one's academic goals within several broad categories: personal goals, academic goals, research goals, educational goals, and financial goals. Learning the art of self-promotion is the means by which many of these goals are achieved. It is important to realize that achieving these goals requires a delicate personal balance between work and home life, and the key ways in which to achieve success require establishment of well thought-out goals, a reliable support structure, realistic and clear expectations, and frequent re-evaluation.

Liverman, D.

2015-12-01

The Sustainable Development Goals are underpinned by a committment to a world that is just, equitable, inclusive and environmentally sustainable and include goals of ending poverty and hunger; universal access to health, education, water, sanitation, energy and decent work; and reducing the risks and impacts of climate change, biodiversity loss, and marine, forest and land degradation. They seek to reduce inequality between and within countries and achieve gender equality. The SDGs build on the apparent success in meeting many of the Millenium Development Goals, including those of reducing poverty, hunger and debt and providing access to water. The science needed to achieve and monitor most of these goals is social science - an area of scholarship that is traditionally undervalued, underfunded, underepresented misunderstood and lacking in detailed data. This paper will provide an overview of the social science that is needed to support the Sustainable Development Goals, with a particular focus on the challenges of monitoring social data over time and within countries, the importance of research design, and of building capacity and credibility in the social sciences. As an example, the paper will discuss the social science that will be needed to achieve Goal 13: Take urgent actions to combat climate change and its impacts, and measuring targets such as strengthening resilience and adaptive capacity, and raising capacities of women, youth, and marginalized communities to manage and respond climate change.

Neurophysiological studies have shown that parietal mirror neurons encode not only actions but also the goal of these actions. Although some mirror neurons will fire whenever a certain action is perceived (goal-independently), most will only fire if the motion is perceived as part of an action with a specific goal. This result is important for the action-understanding hypothesis as it provides a potential neurological basis for such a cognitive ability. It is also relevant for the design of artificial cognitive systems, in particular robotic systems that rely on computational models of the mirror system in their interaction with other agents. Yet, to date, no computational model has explicitly addressed the mechanisms that give rise to both goal-specific and goal-independent parietal mirror neurons. In the present paper, we present a computational model based on a self-organizing map, which receives artificial inputs representing information about both the observed or executed actions and the context in which they were executed. We show that the map develops a biologically plausible organization in which goal-specific mirror neurons emerge. We further show that the fundamental cause for both the appearance and the number of goal-specific neurons can be found in geometric relationships between the different inputs to the map. The results are important to the action-understanding hypothesis as they provide a mechanism for the emergence of goal-specific parietal mirror neurons and lead to a number of predictions: (1) Learning of new goals may mostly reassign existing goal-specific neurons rather than recruit new ones; (2) input differences between executed and observed actions can explain observed corresponding differences in the number of goal-specific neurons; and (3) the percentage of goal-specific neurons may differ between motion primitives.

Regulation is performed by the government on behalf of the public to accomplish a societal goal. However, the public is not necessarily confident that regulatory authority does well enough for the benefit of the public. That is partly because they have less information, competence and resources for monitoring regulatory activities. However, it is a problem that cannot be solved easily only by efforts of the personnel involved. In nuclear industry and regulation, there is increasing concerns of the local community on the decision making related to the safety matters on nuclear facilities. Resident people on NPP sites realize that radiation risk caused by the NPPs is their first concern, whereas the general public as a whole is less concerned with the radiation risk or nuclear safety. Regulatory organizations have less motivation to do their best because they pursue their private or group interests. In this paper, the above mentioned issue has been reviewed in terms of principal agent problem(PAP) theory and also the PAP model for Korean nuclear regulatory system has been developed

Research programmes appear to represent one of the more powerful instruments through which research funders (principals) steer and shape what researchers (agents) do. The fact that agents navigate between different sources and styles of programme funding and that they use programmes to their own ends is readily accommodated within principal-agent theory with the help of concepts such as shirking and defection. Taking a different route, I use three examples of research programming (by the UK, ...

An Analysis of How the Gender and Race of School Principals Influence Their Perception of Multicultural Education

Directory of Open Access Journals (Sweden)

2010-01-01

Full Text Available The purpose of this study was to investigate secondary school principals’ perceptions of multicultural education in a rural southeastern state. The researchers wanted to ascertain whether or not the race or gender of school principals have a role in how those principals view multicultural education in theory (its theoretical value. For the purpose of this study, multicultural education in theory was defined as the belief that multicultural education is for all students, elevates students’ self-esteem, is embedded in cultural pluralism, and recognizes the social, political, and economic community and societal constructs on students of color (Fernandez, 1996. Three hundred and two secondary school principals were surveyed in a designated southeastern state. A significant difference was discovered with regard to the gender of the school principals and their perceptions of the theoretical value of multicultural education.

THE STUDY OF THE CHARACTERIZATION INDICES OF FABRICS BY PRINCIPAL COMPONENT ANALYSIS METHOD

Directory of Open Access Journals (Sweden)

HRISTIAN Liliana

2017-05-01

Full Text Available The paper was pursued to prioritize the worsted fabrics type, for the manufacture of outerwear products by characterization indeces of fabrics, using the mathematical model of Principal Component Analysis (PCA. There are a number of variables with a certain influence on the quality of fabrics, but some of these variables are more important than others, so it is useful to identify those variables to a better understanding the factors which can lead the improving of the fabrics quality. A solution to this problem can be the application of a method of factorial analysis, the so-called Principal Component Analysis, with the final goal of establishing and analyzing those variables which influence in a significant manner the internal structure of combed wool fabrics according to armire type. By applying PCA it is obtained a small number of the linear combinations (principal components from a set of variables, describing the internal structure of the fabrics, which can hold as much information as possible from the original variables. Data analysis is an important initial step in decision making, allowing identification of the causes that lead to a decision- making situations. Thus it is the action of transforming the initial data in order to extract useful information and to facilitate reaching the conclusions. The process of data analysis can be defined as a sequence of steps aimed at formulating hypotheses, collecting primary information and validation, the construction of the mathematical model describing this phenomenon and reaching these conclusions about the behavior of this model.

Babanova, Sofia; Artyushkova, Kateryna; Ulyanova, Yevgenia; Singhal, Sameer; Atanassov, Plamen

2014-01-01

Two statistical methods, design of experiments (DOE) and principal component analysis (PCA) are employed to investigate and improve performance of air-breathing gas-diffusional enzymatic electrodes. DOE is utilized as a tool for systematic organization and evaluation of various factors affecting the performance of the composite system. Based on the results from the DOE, an improved cathode is constructed. The current density generated utilizing the improved cathode (755 ± 39 μA cm-2 at 0.3 V vs. Ag/AgCl) is 2-5 times higher than the highest current density previously achieved. Three major factors contributing to the cathode performance are identified: the amount of enzyme, the volume of phosphate buffer used to immobilize the enzyme, and the thickness of the gas-diffusion layer (GDL). PCA is applied as an independent confirmation tool to support conclusions made by DOE and to visualize the contribution of factors in individual cathode configurations.

Stochastic goal programming based groundwater remediation management under human-health-risk uncertainty

International Nuclear Information System (INIS)

Li, Jing; He, Li; Lu, Hongwei; Fan, Xing

2014-01-01

Highlights: • We propose an integrated optimal groundwater remediation design approach. • The approach can address stochasticity in carcinogenic risks. • Goal programming is used to make the system approaching to ideal operation and remediation effects. • The uncertainty in slope factor is evaluated under different confidence levels. • Optimal strategies are obtained to support remediation design under uncertainty. - Abstract: An optimal design approach for groundwater remediation is developed through incorporating numerical simulation, health risk assessment, uncertainty analysis and nonlinear optimization within a general framework. Stochastic analysis and goal programming are introduced into the framework to handle uncertainties in real-world groundwater remediation systems. Carcinogenic risks associated with remediation actions are further evaluated at four confidence levels. The differences between ideal and predicted constraints are minimized by goal programming. The approach is then applied to a contaminated site in western Canada for creating a set of optimal remediation strategies. Results from the case study indicate that factors including environmental standards, health risks and technical requirements mutually affected and restricted themselves. Stochastic uncertainty existed in the entire process of remediation optimization, which should to be taken into consideration in groundwater remediation design

Women and children compose the largest segment of the more than 1 billion people worldwide who are unable to access needed health care services. To address this and other global health issues, the United Nations brought together world leaders to address growing health inequities, first by establishing the Millennium Development Goals in 2000 and more recently establishing Sustainable Development Goals, which are an intergovernmental set of 17 goals consisting of 169 targets with 304 indicators to measure compliance; they were designed to be applicable to all countries. Goal number 3, "Good Health and Well-Being: Ensure Heathy Lives and Promote Well-Being for All at All Ages," includes targets to improve the health of women and newborns. © 2016 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

Goals and everyday problem solving: manipulating goal preferences in young and older adults.

Science.gov (United States)

Hoppmann, Christiane A; Blanchard-Fields, Fredda

2010-11-01

In the present study, we examined the link between goal and problem-solving strategy preferences in 130 young and older adults using hypothetical family problem vignettes. At baseline, young adults preferred autonomy goals, whereas older adults preferred generative goals. Imagining an expanded future time perspective led older adults to show preferences for autonomy goals similar to those observed in young adults but did not eliminate age differences in generative goals. Autonomy goals were associated with more self-focused instrumental problem solving, whereas generative goals were related to more other-focused instrumental problem solving in the no-instruction and instruction conditions. Older adults were better at matching their strategies to their goals than young adults were. This suggests that older adults may become better at selecting their strategies in accordance with their goals. Our findings speak to a contextual approach to everyday problem solving by showing that goals are associated with the selection of problem-solving strategies.

Comparison of participatively set and assigned goals in the reduction of alcohol use.

Lozano, Brian E; Stephens, Robert S

2010-12-01

The effects of setting goals on goal commitment, self-efficacy for goal achievement, and goal achievement in the context of an alcohol use intervention were examined using an experimental design in which participants were randomized to participatively set goals, assigned goals, and no goal conditions. One hundred and twenty-six heavy-drinking college students received a single cognitive-behavioral assessment/intervention session and completed measures of goal commitment, self-efficacy for goal achievement, and alcohol use. Results were consistent with, and expanded upon, previous research by demonstrating that having a goal for limiting alcohol consumption was predictive of lower quantity and frequency of alcohol use relative to not having a goal. Participation in goal setting yielded greater goal commitment and self-efficacy for goal achievement than assigned goals, but did not result in significantly greater reductions in alcohol use relative to assigned goals. Goal commitment and self-efficacy explained unique variance in the prediction of alcohol use at follow-up. Findings support the importance of goal setting in alcohol interventions and suggest areas for further research. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

Psychological "gel" to bind individuals' goal pursuit: gratitude facilitates goal contagion.

Science.gov (United States)

Jia, Lile; Tong, Eddie M W; Lee, Li Neng

2014-08-01

Past research demonstrates that gratitude affects individuals' self-regulation of behavior primarily through engendering a prosocial tendency. Based on theories proposing that gratitude plays an unique role in fostering communal relationship (e.g., Algoe, 2012), we propose that gratitude can have an incidental effect in facilitating goal contagion: automatically inferring and adopting the goal implied by a social other's behavior. This hypothesis is supported in 3 studies. In Study 1, after being exposed to the behaviors of a social target that implied either a cooperative or a competitive goal, individuals adopted the respective goal and behaved accordingly in a Resource Dilemma Task. This occurred, however, only when they were feeling gratitude and not when they were feeling joy or a neutral mood. In Study 2, after being exposed to a social target's behavior that implied the goal to make money, people feeling gratitude, as compared to those feeling pride or a neutral mood, strove for a future opportunity to earn money. Study 3 further demonstrated that individuals' goal striving behavior was mediated by a heightened level of goal activation. Finally, it was found that gratitude facilitated goal contagion only when the social target was a member of participants' own social group. Through this mechanism, gratitude, thus, seems to bind one's self-regulation with those of social others. Theoretical and practical implications of this new perspective are discussed.

2013-04-01

Full Text Available This study focussed on the socialisation of a new principal in a South African primary school with a strong Christian culture. He was appointed when the predecessor retired after more than two decades. The conceptual framework focuses on the three phases of socialisation: professional socialisation, organisational socialisation and occupational identity, which are used to interpret the study. A qualitative study, which occurred during two phases, investigated the phenomenon, principal succession, in the particular school. The data collection methods included a number of interviews with the principal, a focus group interview with staff members who experienced the previous principal’s leadership practice, and individual interviews with staff members. The following categories emerged from the data analysis: Recalling the previous principal: ‘One sees Mr X [the predecessor] everywhere’; Entry and orientation: ‘I found it intimidating initially’; and Immersion and reshaping: ‘Reins that previously were a bit slack, he is now pulling tight’.Die sosialisering van ’n primêre skoolhoof in Suid-Afrika.

Goals and Psychological Accounting

DEFF Research Database (Denmark)

Koch, Alexander Karl; Nafziger, Julia

We model how people formulate and evaluate goals to overcome self-control problems. People often attempt to regulate their behavior by evaluating goal-related outcomes separately (in narrow psychological accounts) rather than jointly (in a broad account). To explain this evidence, our theory...... of endogenous narrow or broad psychological accounts combines insights from the literatures on goals and mental accounting with models of expectations-based reference-dependent preferences. By formulating goals the individual creates expectations that induce reference points for task outcomes. These goal......-induced reference points make substandard performance psychologically painful and motivate the individual to stick to his goals. How strong the commitment to goals is depends on the type of psychological account. We provide conditions when it is optimal to evaluate goals in narrow accounts. The key intuition...

McAlearney, Ann Scheck; Hefner, Jennifer L

2016-08-01

While preventing health care-associated infections (HAIs) can save lives and reduce health care costs, efforts designed to eliminate HAIs have had mixed results. Variability in contextual factors such as work culture and management practices has been suggested as a potential explanation for inconsistent results across organizations and interventions. We examine goal-setting as a factor contributing to program outcomes in eight hospitals focused on preventing central line-associated bloodstream infections (CLABSIs). We conducted qualitative case studies to compare higher- and lower-performing hospitals, and explored differences in contextual factors that might contribute to performance variation. We present a goal commitment framework that characterizes factors associated with successful CLABSI program outcomes. Across 194 key informant interviews, internal and external moderators and characteristics of the goal itself differentiated actors' goal commitment at higher- versus lower-performing hospitals. Our findings have implications for organizations struggling to prevent HAIs, as well as informing the broader goal commitment literature. © The Author(s) 2015.

Stepping stones: Principal career paths and school outcomes.

Science.gov (United States)

Béteille, Tara; Kalogrides, Demetra; Loeb, Susanna

2012-07-01

More than one out of every five principals leaves their school each year. In some cases, these career changes are driven by the choices of district leadership. In other cases, principals initiate the move, often demonstrating preferences to work in schools with higher achieving students from more advantaged socioeconomic backgrounds. Principals often use schools with many poor or low-achieving students as stepping stones to what they view as more desirable assignments. We use longitudinal data from one large urban school district to study the relationship between principal turnover and school outcomes. We find that principal turnover is, on average, detrimental to school performance. Frequent turnover of school leadership results in lower teacher retention and lower student achievement gains. Leadership changes are particularly harmful for high poverty schools, low-achieving schools, and schools with many inexperienced teachers. These schools not only suffer from high rates of principal turnover but are also unable to attract experienced successors. The negative effect of leadership changes can be mitigated when vacancies are filled by individuals with prior experience leading other schools. However, the majority of new principals in high poverty and low-performing schools lack prior leadership experience and leave when more attractive positions become available in other schools.

Examining the Dynamics of Novation from the Principal Contractor's and Architect's Perspectives

Directory of Open Access Journals (Sweden)

Alan Griffith

2012-11-01

Full Text Available Design and build is a popular form of procurement worldwide. In its conventional form, it is characterised by the integration between design and construction. Novation, a variant of design and build where design responsibility is transferred from designer to contractor as procurement evolves, has gained in popularity. However, the characteristics of the process, although well identified, continue to create confusion and problems for clients and contractors alike. This paper focuses on the dynamics of design and build novation from the principal contractor's and architect's perspectives. It embraces key aspects of both the pre-contract and post-contract environment. Its contribution forms a part of a major UK Government funded research project investigating design and build best practice. The findings presented in this paper broadly indicate that contractors believe novated design and build can be disadvantageous and that considerable fragmentation can be created in what should be an integrated procurement approach.

Students' perceptions of classroom goals influence their adoption of personal goals. To assess different forms of classroom goals, recent studies have favoured an overall measure of performance classroom goals, compared to a two-dimensional assessment of performance-approach and performance-avoidance classroom goals (PAVCG). This paper considered the relationship between students' perceptions of classroom goals and their endorsement of personal achievement goals. We proposed that three (instead of only two) classroom goals need to be distinguished. We aimed to provide evidence for this hypothesis by confirmatory factor analysis (CFA) and also by divergent associations between the respective classroom goal and students' personal goal endorsement. A total of 871 (474 female) 10th grade students from several German high schools participated in this study. Students responded to items assessing their perception of mastery, performance-approach, and performance-avoidance goals in the classroom. Additionally, the students reported how much they personally pursue mastery, performance-approach, and performance-avoidance goals. All items referred to German as a specific school subject. RESULTS.A CFA yielded empirical support for the proposed distinction of three (instead of only two) different kinds of classroom goals. Moreover, in hierarchical linear modelling (HLM) analyses all three classroom goals showed unique associations with students' personal goal adoption. The findings emphasized the need to distinguish performance-approach and PAVCG. Furthermore, our results suggest that multiple classroom goals have interactive effects on students' personal achievement strivings. ©2010 The British Psychological Society.

Modeling the variability of solar radiation data among weather stations by means of principal components analysis

Zarzo, Manuel; Marti, Pau

2011-01-01

Research highlights: →Principal components analysis was applied to R s data recorded at 30 stations. → Four principal components explain 97% of the data variability. → The latent variables can be fitted according to latitude, longitude and altitude. → The PCA approach is more effective for gap infilling than conventional approaches. → The proposed method allows daily R s estimations at locations in the area of study. - Abstract: Measurements of global terrestrial solar radiation (R s ) are commonly recorded in meteorological stations. Daily variability of R s has to be taken into account for the design of photovoltaic systems and energy efficient buildings. Principal components analysis (PCA) was applied to R s data recorded at 30 stations in the Mediterranean coast of Spain. Due to equipment failures and site operation problems, time series of R s often present data gaps or discontinuities. The PCA approach copes with this problem and allows estimation of present and past values by taking advantage of R s records from nearby stations. The gap infilling performance of this methodology is compared with neural networks and alternative conventional approaches. Four principal components explain 66% of the data variability with respect to the average trajectory (97% if non-centered values are considered). A new method based on principal components regression was also developed for R s estimation if previous measurements are not available. By means of multiple linear regression, it was found that the latent variables associated to the four relevant principal components can be fitted according to the latitude, longitude and altitude of the station where data were recorded from. Additional geographical or climatic variables did not increase the predictive goodness-of-fit. The resulting models allow the estimation of daily R s values at any location in the area under study and present higher accuracy than artificial neural networks and some conventional approaches

2016-03-01

Brazil, together with all the member countries of the United Nations, is in a process of adoption of a group of Sustainable Development Goals, including targets and indicators. This article considers the implications of these goals and their proposed targets, for the Semi-Arid region of Brazil. This region has recurring droughts which may worsen with climate change, further weakening the situation of access of water for human consumption in sufficient quantity and quality, and as a result, the health conditions of the exposed populations. This study identifies the relationship between drought and health, in an effort to measure progress in this region (1,135 municipalities), comparing relevant indicators with the other 4,430 municipalities in Brazil, based on census data from 1991, 2000 and 2010. Important inequalities between the municipalities of this region and the municipalities of the rest of Brazil are identified, and discussed in the context of what is necessary for achieving the Sustainable Development Goals in the Semi-arid Region, principally in relation to the measures for adaptation to achieve universal and equitable access to drinking water.

Goal-Oriented Ethics: Framing the Goal-Setting Concretely

Directory of Open Access Journals (Sweden)

Mathew Illathuparampil

2017-10-01

Full Text Available Joseph Selling, professor emeritus from KU Leuven, Belgium, recently made a significant contribution towards ethical methodology. It is in fact a continuation of the in-house conversations that have been in vogue about methods in moral reasoning since Vatican II in the discipline called theological ethics. What is specific about Selling’s attempt is that he re-orients or reframes the evaluation of the moral event to consider human intentionality or motivation before considering human behavior or human acts. He convincingly establishes his method by a meticulous reading of Thomas Aquinas. This paper is a response to the goal-oriented ethics that he has posited. As illustrated below, this paper evaluates the goal-oriented approach as solid and sufficient. While fully endorsing this approach, this paper argues that the process of ethical goal-setting is to be framed concretely. In a concrete historical context, so that a goal-oriented approach fully serves its purpose, this paper proposes that it is to be reinforced by four supportive pillars, which are in fact assumed by Selling in his work. They are openness to human sciences, conversation among various narratives, positing a theological frame for ethical reasoning, and recourse to non-discursive reasoning.

Subjective performance evaluations and reciprocity in principal-agent relations

. In contrast to existing models of reciprocity, we find that agents tend to sanction whenever the feedback of principals is below their subjective self-evaluations even if agents' pay-offs are independent of it. In turn, principals provide more positive feedback (relative to their actual performance assessment......We conduct a laboratory experiment with agents working on, and principals benefiting from, a real effort task in which the agents' performance can only be evaluated subjectively. Principals give subjective performance feedback to agents, and agents have an opportunity to sanction principals...... of the agent) if this does not affect their pay-off....

Trial evaluations in comparison with the 1983 safety goals

International Nuclear Information System (INIS)

Riggs, R.; Sege, G.

1985-06-01

This report provides retrospective comparisons of selected generic regulatory actions to the 1983 NRC safety goals, which had been issued for evaluation during a two-year period. The issues covered are those analyzed by the Office of Nuclear Reactor Regulation (NRR) (assisted in some cases by the Battelle Pacific Northwest Laboratory). The issues include auxiliary feedwater reliability, pressurized thermal shock, power-operated relief valve isolation, asymmetric blowdown loads on PWR primary systems, pool dynamic loads for BWR containments, and steam generator tube rupture. Calculated core-melt frequencies, mortality risks, and cost-benefit ratios are compared with the corresponding safety-goal quantitative design objectives. Considerations that should influence interpretation of the comparisons are discussed. Comments are included on whether and how the safety goals may have helped in the regulatory decision process and on problems encountered

PRINCIPAL'S LEADERSHIP STYLE, AS PERCEIVED BY TEACHERS, IN RELATION TO TEACHER'S EXPERIENCE FACTOR OF SCHOOL CLIMATE IN ELEMENTARY SCHOOLS

Directory of Open Access Journals (Sweden)

Gabriel Pinkas

2017-09-01

Full Text Available The experience of the environment in which the activity is performed is a significant factor of the outcome of this activity, that is, the efficiency of the work and the degree of achieving the goal. Within the work environment, physical and social conditions can be observed. The first, which includes material and technical means, are mostly static, easily perceivable and measurable. Others, which include social relations, are much more susceptible to change, more difficult to perceive and measure, and their experience with different individuals within the same group can be more distinct. Although all members of the group participate in group dynamics and relationships, not all are equally relevant to these processes. Considering the position that carries the right and responsibility of setting up a vision and mission, setting goals, creating conditions for work, making decisions and providing feedback, the leader is in most cases crucial. This paper analyzes the role of elementary school principals in creating a school climate, as a non - material environment in which educational activity is carried out, and in this sense it is a specific group / work organization. An estimate was used to measure both variables, i.e. teacher's experience. The instruments used are Multifactor Leadership Questionnaire - MLQ (Avolio and Bass and School Level Environment Questionnaire - SLEQ (Johnson, Stevens and Zvoch. The survey was conducted in elementary schools in the wider city area of Tuzla, on a sample of 467 teachers and 25 principals. In statistical data processing, multiple regression (Ordinary least squares and direct square discriminatory analysis were applied. The obtained results point to the connection between the perceived leadership style of elementary school principals and the school climate experienced by teachers, especially in the field of innovation in teaching and mutual cooperation.

Deformation quantization is an algebraic but still geometrical way to define noncommutative spacetimes. In order to investigate corresponding gauge theories on such spaces, the geometrical formulation in terms of principal fibre bundles yields the appropriate framework. In this talk I will explain what should be understood by a deformation quantization of principal fibre bundles and how associated vector bundles arise in this context. (author)

Dynamics of multiple-goal pursuit.

Science.gov (United States)

Louro, Maria J; Pieters, Rik; Zeelenberg, Marcel

2007-08-01

The authors propose and test a model of multiple-goal pursuit that specifies how individuals allocate effort among multiple goals over time. The model predicts that whether individuals decide to step up effort, coast, abandon the current goal, or switch to pursue another goal is determined jointly by the emotions that flow from prior goal progress and the proximity to future goal attainment, and proximally determined by changes in expectancies about goal attainment. Results from a longitudinal diary study and 2 experiments show that positive and negative goal-related emotions can have diametrically opposing effects on goal-directed behavior, depending on the individual's proximity to goal attainment. The findings resolve contrasting predictions about the influence of positive and negative emotions in volitional behavior, critically amend the goal gradient hypothesis, and provide new insights into the dynamics and determinants of multiple-goal pursuit.

We provide unified phenomenological description of magnetooptic effects being linear and quadratic in magnetization. The description is based on few principal spectra, describing elements of permittivity tensor up to the second order in magnetization. Each permittivity tensor element for any magnetization direction and any sample surface orientation is simply determined by weighted summation of the principal spectra, where weights are given by crystallographic and magnetization orientations. The number of principal spectra depends on the symmetry of the crystal. In cubic crystals owning point symmetry we need only four principal spectra. Here, the principal spectra are expressed by ab initio calculations for bcc Fe, fcc Co and fcc Ni in optical range as well as in hard and soft x-ray energy range, i.e. at the 2p- and 3p-edges. We also express principal spectra analytically using modified Kubo formula.

Remedial design work plan for the Lower East Fork Poplar Creek Operable Unit, Oak Ridge, Tennessee

International Nuclear Information System (INIS)

1996-02-01

The Remedial Design Work Plan (RDWP) for the Lower East Fork Poplar Creek (EFPC) Operable Unit (OU) in Oak Ridge, Tennessee, has been prepared. The remedial investigation determined that the principal contaminant is mercury, which originated from releases during Y-12 Plant operations, primarily between 1953 and 1963. The recommended alternative, as stated in the Record of Decision (ROD) was to excavate and dispose of floodplain soils contaminated with mercury above the remedial goal option. Thereafter, a public hearing was held to review the proposed plan. Comments were incorporated. The revised selected remedy, per the ROD is to excavate and dispose of floodplain soils contaminated above the remediation goal of 400 parts per million mercury. The approved ROD with this goal will be the basis for remedial design (RD). The RD work plan (RDWP) is composed of six chapters. An introductory chapter describes the purpose and scope of the RDWP, the selected remedy as identified by the ROD; the roles and responsibilities of the RD team members, and the site background information, including site history, contaminants of concern, and site characteristics. Chapter 2 contains the design objectives, RD approach, regulatory considerations during RD, and the design criteria with assumptions. Chapter 3 presents the RD planning process to prepare this RDWP, as well as secondary RD support plans. Chapter 4 describes the scope of the RD activities in more detail and identifies what will be included in the design package. Chapter 5 presents the schedule for performance of the RD activities, identifying key RD milestones. Specific documents used in the preparation of this document are referenced in Chapter 6

The Development of Professional Empowerment Program for Principals by Interorganizational Collaboration and Action Research

Directory of Open Access Journals (Sweden)

Peiying Chen

2015-06-01

Full Text Available As an action research approach through interorganizational collaboration, this study aims to develop an effective professional learning program for enhancing principals’ leadership. There are three phases in this research: program design, implementation, and feedback and reflection. With a comprehensive literature review and focus group interviews, key competences of leadership were identified. The program contents were designed through interorganizational collaboration between academics, local officers, experienced principals, and NGO practitioners. The program contains self-awareness and team building in the dark, leading for the future, curriculum and instructional leadership, systems thinking, Understanding by Design, framework and practice, and World Café dialogue. In Phase II, a four-day workshop program has been held twice in the summer of 2012. Learning feedback was posted on Facebook as informal formative evaluation during the implementation phase. In phase III, opinions and feedbacks from learners, external observers, and curriculum designers were collected to assess the effectiveness of the program. The challenges and revision ideas were proposed at the end of the paper. Through the cycle of “design-act-feedback-revision” of action research with interorganizational collaboration, the present professional development program for principals can be refined and better empower school leaders with new ways of situated learning, collaboration, and reflective thinking. Although this program has been implemented for a few times in the past two years, this paper only explained and discussed the merits and effects of the workshops implemented in the summer of 2012.

Principal component analysis for neural electron/jet discrimination in highly segmented calorimeters

International Nuclear Information System (INIS)

Vassali, M.R.; Seixas, J.M.

2001-01-01

A neural electron/jet discriminator based on calorimetry is developed for the second-level trigger system of the ATLAS detector. As preprocessing of the calorimeter information, a principal component analysis is performed on each segment of the two sections (electromagnetic and hadronic) of the calorimeter system, in order to reduce significantly the dimension of the input data space and fully explore the detailed energy deposition profile, which is provided by the highly-segmented calorimeter system. It is shown that projecting calorimeter data onto 33 segmented principal components, the discrimination efficiency of the neural classifier reaches 98.9% for electrons (with only 1% of false alarm probability). Furthermore, restricting data projection onto only 9 components, an electron efficiency of 99.1% is achieved (with 3% of false alarm), which confirms that a fast triggering system may be designed using few components

Honouring Roles: The Story of a Principal and a Student

Directory of Open Access Journals (Sweden)

Jerome Cranston

2012-11-01

Full Text Available The importance of the teacher-student relationship in educational practice is well established, as is the idea of principal leadership in relationship to staff. Even though principal leadership is regarded as a factor in student success, the principal’s effect is usually assumed to take place via the teaching staff. There is an absence of research about the “lived experience” of direct principal-student relationships that shed lights on the ways in which these relationships play a role in student success and principal transformation. This paper presents two narratives written about a particular set of principal-student interactions experienced by the researcher (principal and participant (student.  The analysis uses a narrative inquiry approach to explore both the individual and collective meanings of this principal-student relationship. The stories and their derived meanings have the potential to enliven and  influence educational practice as they explore the subtleties of the principal-student relationship.

The metaphor of selfish goals is misguided. Organisms can be considered vessels that further the interests of their genes, but not vessels that further the interests of their goals. Although goals can act at cross-purposes to each other and to longevity, such trade-offs are predicted by evolutionary theory. The metaphor of selfish goals provides no purchase on this problem.

Goal-setting in clinical medicine.

Science.gov (United States)

Bradley, E H; Bogardus, S T; Tinetti, M E; Inouye, S K

1999-07-01

The process of setting goals for medical care in the context of chronic disease has received little attention in the medical literature, despite the importance of goal-setting in the achievement of desired outcomes. Using qualitative research methods, this paper develops a theory of goal-setting in the care of patients with dementia. The theory posits several propositions. First, goals are generated from embedded values but are distinct from values. Goals vary based on specific circumstances and alternatives whereas values are person-specific and relatively stable in the face of changing circumstances. Second, goals are hierarchical in nature, with complex mappings between general and specific goals. Third, there are a number of factors that modify the goal-setting process, by affecting the generation of goals from values or the translation of general goals to specific goals. Modifying factors related to individuals include their degree of risk-taking, perceived self-efficacy, and acceptance of the disease. Disease factors that modify the goal-setting process include the urgency and irreversibility of the medical condition. Pertinent characteristics of the patient-family-clinician interaction include the level of participation, control, and trust among patients, family members, and clinicians. The research suggests that the goal-setting process in clinical medicine is complex, and the potential for disagreements regarding goals substantial. The nature of the goal-setting process suggests that explicit discussion of goals for care may be necessary to promote effective patient-family-clinician communication and adequate care planning.

Motivational Goal Bracketing: An Experiment

DEFF Research Database (Denmark)

Koch, Alexander; Nafziger, Julia

We study in an online, real-effort experiment how the bracketing of non-binding goals affects performance in a work-leisure self-control problem. We externally induce the goal bracket - daily goals or a weekly goal - and within that bracket let subjects set goals for how much they want to work over...... a one-week period. Our theoretical model predicts (i) that weekly goals create incentives to compensate for a lower than desired performance today with the promise to work harder tomorrow, whereas daily goals exclude such excuses; (ii) that subjects with daily goals set higher goals in aggregate...... and work harder than those with weekly goals. Our data support these predictions. Surprisingly, however, when goals are combined with an externally enforced commitment that requires subjects to spend less than a minute each day on the task to get started working, performance deteriorates because of high...

An application of principal component analysis to the clavicle and clavicle fixation devices.

Daruwalla, Zubin J; Courtis, Patrick; Fitzpatrick, Clare; Fitzpatrick, David; Mullett, Hannan

2010-03-26

Principal component analysis (PCA) enables the building of statistical shape models of bones and joints. This has been used in conjunction with computer assisted surgery in the past. However, PCA of the clavicle has not been performed. Using PCA, we present a novel method that examines the major modes of size and three-dimensional shape variation in male and female clavicles and suggests a method of grouping the clavicle into size and shape categories. Twenty-one high-resolution computerized tomography scans of the clavicle were reconstructed and analyzed using a specifically developed statistical software package. After performing statistical shape analysis, PCA was applied to study the factors that account for anatomical variation. The first principal component representing size accounted for 70.5 percent of anatomical variation. The addition of a further three principal components accounted for almost 87 percent. Using statistical shape analysis, clavicles in males have a greater lateral depth and are longer, wider and thicker than in females. However, the sternal angle in females is larger than in males. PCA confirmed these differences between genders but also noted that men exhibit greater variance and classified clavicles into five morphological groups. This unique approach is the first that standardizes a clavicular orientation. It provides information that is useful to both, the biomedical engineer and clinician. Other applications include implant design with regard to modifying current or designing future clavicle fixation devices. Our findings support the need for further development of clavicle fixation devices and the questioning of whether gender-specific devices are necessary.

PRA has many faces - can the safety goal be well-posed

International Nuclear Information System (INIS)

Bargmann, H.

1983-01-01

The question is discussed whether probabilistic reliability problems can, principally, be well-posed in practical situations. The problem is reduced to the question whether an underlying probabilistic experiment which is, essentially, the set of outcomes can be precisely specified such that the solution of the problem is unique. Upon reexamination of a classical paradox due to Bertrand and consideration of a typical problem of structural reliability we conclude that the possibility of well-posing a reliability problem should be considered illusory, for fundamental reasons which are inherent in practical situations. In particular, it should not be assumed that a quantitative safety goal could be verified. Generally, a probabilistic assessment should be considered as a quantitative method for establishing rational results which should, however, not be viewed as quantitative measures but as qualitative guides

Self-regulation of health behavior: social psychological approaches to goal setting and goal striving.

Science.gov (United States)

Mann, Traci; de Ridder, Denise; Fujita, Kentaro

2013-05-01

The goal of this article is to review and highlight the relevance of social psychological research on self-regulation for health-related theory and practice. We first review research on goal setting, or determining which goals to pursue and the criteria to determine whether one has succeeded. We discuss when and why people adopt goals, what properties of goals increase the likelihood of their attainment, and why people abandon goals. We then review research on goal striving, which includes the planning and execution of actions that lead to goal attainment, and the processes that people use to shield their goals from being disrupted by other competing goals, temptations, or distractions. We describe four types of strategies that people use when pursuing goals. We find that self-regulation entails the operation of a number of psychological mechanisms, and that there is no single solution that will help all people in all situations. We recommend a number of strategies that can help people to more effectively set and attain health-related goals. We conclude that enhancing health behavior requires a nuanced understanding and sensitivity to the varied, dynamic psychological processes involved in self-regulation, and that health is a prototypical and central domain in which to examine the relevance of these theoretical models for real behavior. We discuss the implications of this research for theory and practice in health-related domains. PsycINFO Database Record (c) 2013 APA, all rights reserved.

3D face recognition with asymptotic cones based principal curvatures

KAUST Repository

Tang, Yinhang

2015-05-01

The classical curvatures of smooth surfaces (Gaussian, mean and principal curvatures) have been widely used in 3D face recognition (FR). However, facial surfaces resulting from 3D sensors are discrete meshes. In this paper, we present a general framework and define three principal curvatures on discrete surfaces for the purpose of 3D FR. These principal curvatures are derived from the construction of asymptotic cones associated to any Borel subset of the discrete surface. They describe the local geometry of the underlying mesh. First two of them correspond to the classical principal curvatures in the smooth case. We isolate the third principal curvature that carries out meaningful geometric shape information. The three principal curvatures in different Borel subsets scales give multi-scale local facial surface descriptors. We combine the proposed principal curvatures with the LNP-based facial descriptor and SRC for recognition. The identification and verification experiments demonstrate the practicability and accuracy of the third principal curvature and the fusion of multi-scale Borel subset descriptors on 3D face from FRGC v2.0.

School officials and nurses play an important role in facilitating asthma management in schools. Little is known about their perspectives on in-school asthma management and barriers to physical activity (PA) at school. The goal of this study is to explore school officials' and nurses' perspectives on asthma care and barriers to PA in children with asthma attending New York City schools. We conducted qualitative, semistructured interviews with 10 principals, 3 assistant principals, and 9 nurses in 10 Bronx, New York elementary schools. Sampling continued until thematic saturation was reached. Interviews were recorded, transcribed, and coded for common themes. The thematic and content review was subsequently used to analyze interview data. Emerging themes were discussed and agreed on by both investigators. Three main categories arose from the analysis: (1) procedures and policies around asthma management in school, (2) barriers to effective medication administration in school, and (3) barriers to PA in children with asthma. Participants identified gaps to in-school asthma management and barriers to PA participation: ineffective ways of identifying students with asthma; lack of written procedures for asthma management; difficulty in meeting the administrative requirements to administer asthma medication; lack of knowledge and training on asthma management for the parents, students, and school staff; parental limitation of children's PA; and schools not meeting the state physical education requirement. Our findings suggest the need for policy reform on asthma management and PA in urban schools and should be considered in the design of future interventions.

Aerodynamic multi-objective integrated optimization based on principal component analysis

Jiangtao HUANG

2017-08-01

Full Text Available Based on improved multi-objective particle swarm optimization (MOPSO algorithm with principal component analysis (PCA methodology, an efficient high-dimension multi-objective optimization method is proposed, which, as the purpose of this paper, aims to improve the convergence of Pareto front in multi-objective optimization design. The mathematical efficiency, the physical reasonableness and the reliability in dealing with redundant objectives of PCA are verified by typical DTLZ5 test function and multi-objective correlation analysis of supercritical airfoil, and the proposed method is integrated into aircraft multi-disciplinary design (AMDEsign platform, which contains aerodynamics, stealth and structure weight analysis and optimization module. Then the proposed method is used for the multi-point integrated aerodynamic optimization of a wide-body passenger aircraft, in which the redundant objectives identified by PCA are transformed to optimization constraints, and several design methods are compared. The design results illustrate that the strategy used in this paper is sufficient and multi-point design requirements of the passenger aircraft are reached. The visualization level of non-dominant Pareto set is improved by effectively reducing the dimension without losing the primary feature of the problem.

 To examine the association between the presence of individual principal investigators' financial ties to the manufacturer of the study drug and the trial's outcomes after accounting for source of research funding.  Cross sectional study of randomized controlled trials (RCTs).  Studies published in "core clinical" journals, as identified by Medline, between 1 January 2013 and 31 December 2013.  Random sample of RCTs focused on drug efficacy.  Association between financial ties of principal investigators and study outcome.  A total of 190 papers describing 195 studies met inclusion criteria. Financial ties between principal investigators and the pharmaceutical industry were present in 132 (67.7%) studies. Of 397 principal investigators, 231 (58%) had financial ties and 166 (42%) did not. Of all principal investigators, 156 (39%) reported advisor/consultancy payments, 81 (20%) reported speakers' fees, 81 (20%) reported unspecified financial ties, 52 (13%) reported honorariums, 52 (13%) reported employee relationships, 52 (13%) reported travel fees, 41 (10%) reported stock ownership, and 20 (5%) reported having a patent related to the study drug. The prevalence of financial ties of principal investigators was 76% (103/136) among positive studies and 49% (29/59) among negative studies. In unadjusted analyses, the presence of a financial tie was associated with a positive study outcome (odds ratio 3.23, 95% confidence interval 1.7 to 6.1). In the primary multivariate analysis, a financial tie was significantly associated with positive RCT outcome after adjustment for the study funding source (odds ratio 3.57 (1.7 to 7.7). The secondary analysis controlled for additional RCT characteristics such as study phase, sample size, country of first authors, specialty, trial registration, study design, type of analysis, comparator, and outcome measure. These characteristics did not appreciably affect the relation between financial ties and study outcomes (odds ratio 3.37, 1

Goal conflict and goal facilitation in community-based cardiac rehabilitation: a theory-based interview study.

Presseau, Justin; Boyd, Emily; Francis, Jill J; Sniehotta, Falko F

2015-01-01

Theories often consider behaviors in isolation of conflicting and facilitating personal goals. We conducted interviews with 13 people in cardiac rehabilitation, investigating whether eliciting physical activity (PA) control beliefs sufficiently captures goal conflict and goal facilitation. We assessed PA, intention, and control beliefs using standard elicitation methods and then assessed goal conflict and goal facilitation. Twelve participants described conflicting, and all described facilitating, personal goals. Most goal facilitation (94%) and conflict (82%) beliefs were identified beyond the control belief elicitation. Goal facilitation and conflict are not captured in a standard control belief elicitation and may supplement single-behavior models to understand PA.

Liu, Shuyan; Schad, Daniel J; Kuschpel, Maxim S; Rapp, Michael A; Heinz, Andreas

2016-01-01

Different systems for habitual versus goal-directed control are thought to underlie human decision-making. Working memory is known to shape these decision-making systems and their interplay, and is known to support goal-directed decision making even under stress. Here, we investigated if and how decision systems are differentially influenced by breaks filled with diverse everyday life activities known to modulate working memory performance. We used a within-subject design where young adults listened to music and played a video game during breaks interleaved with trials of a sequential two-step Markov decision task, designed to assess habitual as well as goal-directed decision making. Based on a neurocomputational model of task performance, we observed that for individuals with a rather limited working memory capacity video gaming as compared to music reduced reliance on the goal-directed decision-making system, while a rather large working memory capacity prevented such a decline. Our findings suggest differential effects of everyday activities on key decision-making processes.

Assessment of patient knowledge of diabetic goals, self-reported medication adherence, and goal attainment

Whitley HP

2006-12-01

Full Text Available Background: Medication adherence is an integral aspect of disease state management for patients with chronic illnesses, including diabetes mellitus. It has been hypothesized that patients with diabetes who have poor medication adherence may have less knowledge of overall therapeutic goals and may be less likely to attain these goals. Objective: The purpose of this study was to assess self-reported medication adherence, knowledge of therapeutic goals (hemoglobin A1C [A1C], low density lipoprotein cholesterol [LDL-C] and blood pressure [BP], and goal attainment in adult patients with diabetes. Methods: A survey was created to assess medication adherence, knowledge of therapeutic goals, and goal attainment for adult patients with diabetes followed at an internal medicine or a family medicine clinic. Surveys were self-administered prior to office visits. Additional data were collected from the electronic medical record. Statistical analysis was performed. Results: A total of 149 patients were enrolled. Knowledge of therapeutic goals was reported by 14%, 34%, and 18% of survived patients for LDL-C, BP, and A1C, respectively. Forty-six percent, 37%, and 40% of patients achieved LDL-C, BP, and A1C goals, respectively. Low prescribing of cholesterol-lowering medications was an interesting secondary finding; 36% of patients not at LDL-C goal had not been prescribed a medication targeted to lower cholesterol. Forty-eight percent of patients were medication non-adherent; most frequently reported reasons for non-adherence were forgot (34% and too expensive (14%. Patients at A1C goal were more adherent than patients not at goal (p=0.025. Conclusion: The majority did not reach goals and were unknowledgeable of goals; however, most were provided prescriptions to treat these parameters. Goal parameters should be revisited often amongst multidisciplinary team members with frequent and open communications. Additionally, it is imperative that practitioners discuss

Punishment goals of crime victims.

Science.gov (United States)

Orth, Uli

2003-04-01

Research on subjective punishment goals has focused on the perspective of third-party observers of criminal offenses and neglected the perspective of victims. This study investigates punishment goals among 174 adult crime victims (rape and nonsexual assault) for each participant's real criminal case. Scales measuring support for punishment goals are constructed by factor analysis of an 18-item list. Results show that 5 highly supported goals can be distinguished: retaliation, recognition of victim status, confirmation of societal values, victim security, and societal security. Analysis of relations between punishment goal scales and personal variables, situational variables, and demanded punishment severity corroborates the view that the punishment goals revealed can be classified according to the two independent dichotomies of moral versus instrumental goals, and micro versus macro goals.

To evaluate the usefulness of a diabetes self-management guide and a brief counseling intervention in helping patients set and achieve their behavioral goals. We conducted a quasi-experimental study using a one group pretest posttest design to assess the effectiveness of a goal setting intervention along with a self-management guide. English- and Spanish-speaking patients with diabetes had one in-person session and two telephone follow-up calls with a non-clinical provider over a 12-16-week period. At each call and at the end of the study, we assessed success in achieving behavioral goals and problem solving toward those goals. Satisfaction with the self-management guide was assessed at the end of the study. We enrolled 250 patients across three sites and 229 patients completed the study. Most patients chose to set goals in diet and exercise domains. 93% of patients achieved at least one behavioral goal during the study and 73% achieved at least two behavioral goals. Many patients exhibited problem solving behavior to achieve their goals. We found no significant differences in reported achievement of behavior goals by literacy or language. Patients were very satisfied with the guide. A brief goal setting intervention along with a diabetes self-management guide helped patients set and achieve healthy behavioral goals. Non-clinical providers can successfully help a diverse range of patients with diabetes set and achieve behavioral goals.

Model and system learners, optimal process constructors and kinetic theory-based goal-oriented design: A new paradigm in materials and processes informatics

Science.gov (United States)

Abisset-Chavanne, Emmanuelle; Duval, Jean Louis; Cueto, Elias; Chinesta, Francisco

2018-05-01

Traditionally, Simulation-Based Engineering Sciences (SBES) has relied on the use of static data inputs (model parameters, initial or boundary conditions, … obtained from adequate experiments) to perform simulations. A new paradigm in the field of Applied Sciences and Engineering has emerged in the last decade. Dynamic Data-Driven Application Systems [9, 10, 11, 12, 22] allow the linkage of simulation tools with measurement devices for real-time control of simulations and applications, entailing the ability to dynamically incorporate additional data into an executing application, and in reverse, the ability of an application to dynamically steer the measurement process. It is in that context that traditional "digital-twins" are giving raise to a new generation of goal-oriented data-driven application systems, also known as "hybrid-twins", embracing models based on physics and models exclusively based on data adequately collected and assimilated for filling the gap between usual model predictions and measurements. Within this framework new methodologies based on model learners, machine learning and kinetic goal-oriented design are defining a new paradigm in materials, processes and systems engineering.

A principal skeleton algorithm for standardizing confocal images of fruit fly nervous systems

Science.gov (United States)

Qu, Lei; Peng, Hanchuan

2010-01-01

Motivation: The fruit fly (Drosophila melanogaster) is a commonly used model organism in biology. We are currently building a 3D digital atlas of the fruit fly larval nervous system (LNS) based on a large collection of fly larva GAL4 lines, each of which targets a subset of neurons. To achieve such a goal, we need to automatically align a number of high-resolution confocal image stacks of these GAL4 lines. One commonly employed strategy in image pattern registration is to first globally align images using an affine transform, followed by local non-linear warping. Unfortunately, the spatially articulated and often twisted LNS makes it difficult to globally align the images directly using the affine method. In a parallel project to build a 3D digital map of the adult fly ventral nerve cord (VNC), we are confronted with a similar problem. Results: We proposed to standardize a larval image by best aligning its principal skeleton (PS), and thus used this method as an alternative of the usually considered affine alignment. The PS of a shape was defined as a series of connected polylines that spans the entire shape as broadly as possible, but with the shortest overall length. We developed an automatic PS detection algorithm to robustly detect the PS from an image. Then for a pair of larval images, we designed an automatic image registration method to align their PSs and the entire images simultaneously. Our experimental results on both simulated images and real datasets showed that our method does not only produce satisfactory results for real confocal larval images, but also perform robustly and consistently when there is a lot of noise in the data. We also applied this method successfully to confocal images of some other patterns such as the adult fruit fly VNC and center brain, which have more complicated PS. This demonstrates the flexibility and extensibility of our method. Availability: The supplementary movies, full size figures, test data, software, and tutorial on

Multilevel sparse functional principal component analysis.

Science.gov (United States)

Di, Chongzhi; Crainiceanu, Ciprian M; Jank, Wolfgang S

2014-01-29

We consider analysis of sparsely sampled multilevel functional data, where the basic observational unit is a function and data have a natural hierarchy of basic units. An example is when functions are recorded at multiple visits for each subject. Multilevel functional principal component analysis (MFPCA; Di et al. 2009) was proposed for such data when functions are densely recorded. Here we consider the case when functions are sparsely sampled and may contain only a few observations per function. We exploit the multilevel structure of covariance operators and achieve data reduction by principal component decompositions at both between and within subject levels. We address inherent methodological differences in the sparse sampling context to: 1) estimate the covariance operators; 2) estimate the functional principal component scores; 3) predict the underlying curves. Through simulations the proposed method is able to discover dominating modes of variations and reconstruct underlying curves well even in sparse settings. Our approach is illustrated by two applications, the Sleep Heart Health Study and eBay auctions.

Principals, Trust, and Cultivating Vibrant Schools

Directory of Open Access Journals (Sweden)

Megan Tschannen-Moran

2015-03-01

Full Text Available Although principals are ultimately held accountable to student learning in their buildings, the most consistent research results have suggested that their impact on student achievement is largely indirect. Leithwood, Patten, and Jantzi proposed four paths through which this indirect influence would flow, and the purpose of this special issue is to examine in greater depth these mediating variables. Among mediating variables, we assert that trust is key. In this paper, we explore the evidence that points to the role that faculty trust in the principal plays in student learning and how principals can cultivate trust by attending to the five facets of trust, as well as the correlates of trust that mediate student learning, including academic press, collective teacher efficacy, and teacher professionalism. We argue that trust plays a role in each of the four paths identified by Leithwood, Patten, and Jantzi. Finally, we explore possible new directions for future research.

A major goal in stroke rehabilitation is the establishment of more effective physical therapy techniques to recover postural stability. Functional Principal Component Analysis provides greater insight into recovery trends. However, when missing values exist, obtaining functional data presents some difficulties. The purpose of this study was to reveal an alternative technique for obtaining the Functional Principal Components without requiring the conversion to functional data beforehand and to investigate this methodology to determine the effect of specific physical therapy techniques in balance recovery trends in elderly subjects with hemiplegia post-stroke. A randomized controlled pilot trial was developed. Thirty inpatients post-stroke were included. Control and target groups were treated with the same conventional physical therapy protocol based on functional criteria, but specific techniques were added to the target group depending on the subjects' functional level. Postural stability during standing was quantified by posturography. The assessments were performed once a month from the moment the participants were able to stand up to six months post-stroke. The target group showed a significant improvement in postural control recovery trend six months after stroke that was not present in the control group. Some of the assessed parameters revealed significant differences between treatment groups (P Functional Principal Component Analysis to be performed when data is scarce. Moreover, it allowed the dynamics of recovery of two different treatment groups to be determined, showing that the techniques added in the target group increased postural stability compared to the base protocol.

An application of principal component analysis to the clavicle and clavicle fixation devices

Directory of Open Access Journals (Sweden)

Fitzpatrick David

2010-03-01

Full Text Available Abstract Background Principal component analysis (PCA enables the building of statistical shape models of bones and joints. This has been used in conjunction with computer assisted surgery in the past. However, PCA of the clavicle has not been performed. Using PCA, we present a novel method that examines the major modes of size and three-dimensional shape variation in male and female clavicles and suggests a method of grouping the clavicle into size and shape categories. Materials and methods Twenty-one high-resolution computerized tomography scans of the clavicle were reconstructed and analyzed using a specifically developed statistical software package. After performing statistical shape analysis, PCA was applied to study the factors that account for anatomical variation. Results The first principal component representing size accounted for 70.5 percent of anatomical variation. The addition of a further three principal components accounted for almost 87 percent. Using statistical shape analysis, clavicles in males have a greater lateral depth and are longer, wider and thicker than in females. However, the sternal angle in females is larger than in males. PCA confirmed these differences between genders but also noted that men exhibit greater variance and classified clavicles into five morphological groups. Discussion And Conclusions This unique approach is the first that standardizes a clavicular orientation. It provides information that is useful to both, the biomedical engineer and clinician. Other applications include implant design with regard to modifying current or designing future clavicle fixation devices. Our findings support the need for further development of clavicle fixation devices and the questioning of whether gender-specific devices are necessary.

Shopping the way to my goals: an analysis of purchase impact on perceived goal progress

Directory of Open Access Journals (Sweden)

Manuela Albornoz Gonçalves

Full Text Available Abstract This article examines the impact of goal related purchases on goal progress perception, and whether this perception depends on the strength of association between product and goal. To test how consumers perceive the act of purchasing goal-related products, three experiments were conducted in an online setting. Participants exposed to purchasing situations perceived greater goal progress than participants exposed to usage situation or a control group. In addition, studies show that this effect is a result of strength of association between product and goal, since participants exposed to more instrumental products perceived greater goal progress than participants exposed to less instrumental products. Therefore, these studies demonstrate how consumers interpret goal related purchases, and the mechanism that influences this interpretation.

Human performance in orbit is currently limited by several factors beyond the intrinsic awkwardness of motor control in weightlessness. Cognitive functioning can be affected by such factors as cumulative sleep loss, stress and the psychological effects of long-duration small-group isolation. When an astronaut operates a scientific experiment, the performance decrement associated with such factors can lead to lost or poor quality data and even the total loss of a scientific objective, at great cost to the sponsors and to the dismay of the Principal Investigator. In long-duration flights, as anticipated on the International Space Station and on any planetary exploration, the experimental model is further complicated by long delays between training and experiment, and the large number of experiments each crew member must perform. Although no documented studies have been published on the subject, astronauts report that an unusually large number of simple errors are made in space. Whether a result of the effects of microgravity, accumulated fatigue, stress or other factors, this pattern of increased error supports the need for a computerized decision-making aid for astronauts performing experiments. Artificial intelligence and expert systems might serve as powerful tools for assisting experiments in space. Those conducting space experiments typically need assistance exactly when the planned checklist does not apply. Expert systems, which use bits of human knowledge and human methods to respond appropriately to unusual situations, have a flexibility that is highly desirable in circumstances where an invariably predictable course of action/response does not exist. Frequently the human expert on the ground is unavailable, lacking the latest information, or not consulted by the astronaut conducting the experiment. In response to these issues, we have developed "Principal Investigator-in-a-Box," or [PI], to capture the reasoning process of the real expert, the Principal

Goal setting in psychotherapy: the relevance of approach and avoidance goals for treatment outcome.

Science.gov (United States)

Wollburg, Eileen; Braukhaus, Christoph

2010-07-01

The present study is the first aimed at investigating the influence of goal definition on treatment outcome in a sample of depressed patients. Data from 657 inpatients admitted to a psychosomatic clinic in Germany being treated in a cognitive-behavioral therapy program were analyzed. Treatment goals were identified as either approach or avoidance, and the sample was classified accordingly. Patients who identified approach goals only were placed in the approach group, and those who identified at least one avoidance goal were placed in the avoidance group. Results showed that framing goals using avoidance terms was associated with less symptomatic improvement but did not affect goal attainment. Findings from this research should be utilized in practice not only for process management such as individual treatment planning but also to control outcome quality. Furthermore, goal definition should be considered as a control variable in research on depression.

African-American Female Students and STEM: Principals' Leadership Perspectives

Science.gov (United States)

Sampson, Kristin Morgan

As the U.S. becomes more diverse, school leaders, major corporations, and areas of national defense continue to investigate science, technology, engineering and math (STEM) education issues. African-American female students have historically been underrepresented in STEM fields, yet educational leadership research, examining this population is limited. The purpose of this qualitative study was to explore how principals support African-American female students in schools with a STEM program. The Critical Race Theory (CRT)was used as a theoretical framework to highlight the inadequacies to support educational inequalities. The application of the CRT in this study is due to the embedded inequality practices within the educational system, that have resulted in the underrepresentation of African-American female students in STEM. To complement CRT, the transformative leadership model was also utilized to examine the emancipatory leadership practices principals utilized. These theories framed the context of this study by recognizing the need to address how support is actualized to African-American female students in STEM by their principals. A case study approach was an appropriate method to answer the two research questions, 1) How do principals feel they support African-American female students in their STEM programs? and 2) What practices do principals engage in that support underrepresented students in STEM? This approach intended to uncover how a principal leads a multifaceted population of underrepresented students in STEM programs. Two principals of STEM schools, where more than 50% of the population were African-American, were interviewed and observed completing daily operations at community-wide events. The STEM Coordinators and a teacher were also interviewed, and test scores were examined to provide further information about the STEM program, and public records were obtained to analyze the principals' means of communication. I found that principals supported

This study's purpose was to describe the occupational needs and goals of women residing in a domestic violence shelter and their self-perceived changes in satisfaction and occupational performance. Using a retrospective design, data from 68 occupational therapy evaluations from two domestic violence shelter settings were examined. Data were analyzed by coding problem areas and occupational goals and calculating frequencies for these variables. Where data were available, we also analyzed changes in pre- and postscores for self-perceived satisfaction and occupational performance (n = 25). The most common problem areas were leisure, education, work, child rearing, and health management. The most common goals were in the areas of education, work, health management, child rearing, and home management. Retrospective pre- and postchange scores in performance and satisfaction for 25 women were statistically significant. Findings provide direction for, and highlight the importance of occupational therapy services within domestic violence shelters as women regain their life skills.

Design of neutron detectors utilising luminescent glass

International Nuclear Information System (INIS)

Spowart, A.R.

1983-01-01

Impetus for the development of new neutron detector designs has derived from the worldwide commissioning of neutron spallation sources. The design concepts, and principal methods of utilisation of these major installations, have been recently reviewed. Their principal feature of interest is their broadband neutron emission allowing neutron investigations of all types of structure in materials from biological molecules to steels. Conventional neutron detectors are gas-filled devices, based on BF/sub 3/ or /sup 3/He gas. Their major advantage is their intrinsically low background count. Their principal disadvantage is their slow response time (10-100 μs), high cost and relative lack of flexibility in design to cope with large areas or complex geometry detection. They are, however, long established and the research facilities around the world have a heavy investment in the interpretative hardware for gas detectors

Incremental Tensor Principal Component Analysis for Handwritten Digit Recognition

Directory of Open Access Journals (Sweden)

Chang Liu

2014-01-01

Full Text Available To overcome the shortcomings of traditional dimensionality reduction algorithms, incremental tensor principal component analysis (ITPCA based on updated-SVD technique algorithm is proposed in this paper. This paper proves the relationship between PCA, 2DPCA, MPCA, and the graph embedding framework theoretically and derives the incremental learning procedure to add single sample and multiple samples in detail. The experiments on handwritten digit recognition have demonstrated that ITPCA has achieved better recognition performance than that of vector-based principal component analysis (PCA, incremental principal component analysis (IPCA, and multilinear principal component analysis (MPCA algorithms. At the same time, ITPCA also has lower time and space complexity.

The present study examined the effect of achievement goals on metacognitive judgments, such as judgments of learning (JOLs) and metacomprehension judgments, and actual recall performance. We conducted five experiments manipulating the instruction of achievement goals. In each experiment, participants were instructed to adopt mastery-approach goals (i.e., develop their own mental ability through a memory task) or performance-approach goals (i.e., demonstrate their strong memory ability through getting a high score on a memory task). The results of Experiments 1 and 2 showed that JOLs of word pairs in the performance-approach goal condition tended to be higher than those in the mastery-approach goal condition. In contrast, cued recall performance did not differ between the two goal conditions. Experiment 3 also demonstrated that metacomprehension judgments of text passages were higher in the performance-approach goal condition than in the mastery-approach goals condition, whereas test performance did not differ between conditions. These findings suggest that achievement motivation affects metacognitive judgments during learning, even when achievement motivation does not influence actual performance. PMID:28983496

From goal motivation to goal progress: the mediating role of coping in the Self-Concordance Model.

Gaudreau, Patrick; Carraro, Natasha; Miranda, Dave

2012-01-01

The present studies examined the mediating role of self-regulatory mechanisms in the relationship between goal motivation and goal progress in the Self-Concordance Model. First, a systematic review, using meta-analytical path analysis, supported the mediating role of effort and action planning in the positive association between autonomous goal motivation and goal progress. Second, results from two additional empirical studies, using structural equation modeling, lent credence to the mediating role of coping in the relationship between goal motivation and goal progress of university students. Autonomous goal motivation was positively associated with task-oriented coping, which predicted greater goal progress during midterm exams (Study 1, N=702) and at the end of the semester in a different sample (Study 2, N=167). Controlled goal motivation was associated with greater disengagement-oriented coping (Study 1 and Study 2) and lesser use of task-oriented coping (Study 2), which reduced goal progress. These results held up after controlling for perceived stress (Study 2). Our findings highlight the importance of coping in the "inception-to-attainment" goal process because autonomous goal motivation indirectly rather than directly predicts goal progress of university students through their usage of task-oriented coping.

Gadomski, Adam M.

1986-01-01

The new methodology of the goal oriented description of an artificial system is presented. In the SPG approach (System-Process-Goal) it is assumed that the knowledge necessary for achieving the goal is available but it is not ordered or ordered for other purposes. The aim of SPG is to give the description of the analyzed system in form of network by decomposition of goal-system relationships using uniform and mathematical formalism. The SPG approach is useful to build a reactor operator aid system. This paper presents the conception of the application of the SPG approach to the decomposition of TRIGA RC-1 dynamics and for designing of TRIGA diagnostic algorithms. (author)

Goal pursuit, goal adjustment, and affective well-being following lower limb amputation.

Coffey, Laura; Gallagher, Pamela; Desmond, Deirdre; Ryall, Nicola

2014-05-01

This study examined the relationships between tenacious goal pursuit (TGP), flexible goal adjustment (FGA), and affective well-being in a sample of individuals with lower limb amputations. Cross-sectional, quantitative. Ninety-eight patients recently admitted to a primary prosthetic rehabilitation programme completed measures of TGP, FGA, positive affect, and negative affect. Hierarchical regression analyses revealed that TGP and FGA accounted for a significant proportion of the variance in both positive and negative affect, controlling for sociodemographic and clinical characteristics. TGP was significantly positively associated with positive affect, while FGA was significantly negatively associated with negative affect. Moderated regression analyses indicated that the beneficial effect of FGA on negative affect was strongest at high levels of amputation-related pain intensity and low levels of TGP. TGP and FGA appear to influence subjective well-being in different ways, with TGP promoting the experience of positive affect and FGA buffering against negative affect. TGP and FGA may prove useful in identifying individuals at risk of poor affective outcomes following lower limb amputation and represent important targets for intervention in this patient group. What is already known on this subject? The loss of a limb has a significant impact on several important life domains. Although some individuals experience emotional distress following amputation, the majority adjust well to their limb loss, with some achieving positive change or growth as a result of their experiences. Theories of self-regulation propose that disruptions in goal attainment have negative affective consequences. The physical, social, and psychological upheaval caused by limb loss is likely to threaten the attainment of valued goals, which may leave individuals vulnerable to negative psychosocial outcomes if they do not regulate their goals in response to these challenges. According to the dual

Does goal relevant episodic future thinking amplify the effect on delay discounting?

Science.gov (United States)

O'Donnell, Sara; Oluyomi Daniel, Tinuke; Epstein, Leonard H

2017-05-01

Delay discounting (DD) is the preference for smaller immediate rewards over larger delayed rewards. Research shows episodic future thinking (EFT), or mentally simulating future experiences, reframes the choice between small immediate and larger delayed rewards, and can reduce DD. Only general EFT has been studied, whereby people reframe decisions in terms of non-goal related future events. Since future thinking is often goal-oriented and leads to greater activation of brain regions involved in prospection, goal-oriented EFT may be associated with greater reductions in DD than general goal-unrelated EFT. The present study (n=104, M age =22.25, SD=3.42; 50% Female) used a between-subjects 2×2 factorial design with type of episodic thinking (Goal, General) and temporal perspective (Episodic future versus recent thinking; EFT vs ERT) as between factors. Results showed a significant reduction in DD for EFT groups (p<0.001, Cohen's d effect size=0.89), and goal-EFT was more effective than general-EFT on reducing DD (p=0.03, d=0.64).

2011-01-01

Goals are an important motivator. But little is known about why and how people set them. We address this issue in a model based on two stylized facts. i) Goals serve as reference points for performance. ii) Present-biased preferences create self-control problems. We show the power and limits...... of self-regulation through goals. Goals increase an individual's motivation - but only up to a certain point. And they are painful self-disciplining devices. Greater self-control problems may result in tougher goals; but for a severe present bias goals either lack motivating force, or are too painful...

Predicting race performance in triathlon: the role of perfectionism, achievement goals, and personal goal setting.

Science.gov (United States)

Stoeber, Joachim; Uphill, Mark A; Hotham, Sarah

2009-04-01

The question of how perfectionism affects performance is highly debated. Because empirical studies examining perfectionism and competitive sport performance are missing, the present research investigated how perfectionism affected race performance and what role athletes' goals played in this relationship in two prospective studies with competitive triathletes (Study 1: N = 112; Study 2: N = 321). Regression analyses showed that perfectionistic personal standards, high performance-approach goals, low performance-avoidance goals, and high personal goals predicted race performance beyond athletes' performance level. Moreover, the contrast between performance-avoidance and performance-approach goals mediated the relationship between perfectionistic personal standards and performance, whereas personal goal setting mediated the relationship between performance-approach goals and performance. The findings indicate that perfectionistic personal standards do not undermine competitive performance, but are associated with goals that help athletes achieve their best possible performance.

Implicit theories about intelligence and growth (personal best) goals: Exploring reciprocal relationships.

Martin, Andrew J

2015-06-01

There has been increasing interest in growth approaches to students' academic development, including value-added models, modelling of academic trajectories, growth motivation orientations, growth mindsets, and growth goals. This study sought to investigate the relationships between implicit theories about intelligence (incremental and entity theories) and growth (personal best, PB) goals - with particular interest in the ordering of factors across time. The study focused on longitudinal data of 969 Australian high school students. The classic cross-lagged panel design (using structural equation modelling) was employed to shed light on the ordering of Time 1 growth goals, incremental theories, and entity theories relative to Time 2 (1 year later) growth goals, incremental theories, and entity theories. Findings showed that Time 1 growth goals predicted Time 2 incremental theories (positively) and entity theories (negatively); Time 1 entity and incremental theories negatively predicted Time 2 incremental and entity theories respectively; but, Time 1 incremental theories and entity theories did not predict growth goals at Time 2. This suggests that entity and incremental theories are negatively reciprocally related across time, but growth goals seem to be directionally salient over incremental and entity theories. Implications for promoting growth goals and growth mindsets are discussed. © 2014 The British Psychological Society.

Emergency planning simplification: Why ALWR designs shall support this goal

International Nuclear Information System (INIS)

Tripputi, I.

2004-01-01

Emergency Plan simplification, could be achieved only if it can proved, in a context of balanced national health protection policies, that there is a reduced or no technical need for some elements of it and that public protection is assured in all considered situations regardless of protective actions outside the plant. These objectives may be technically supported if one or more of the following conditions are complied with: 1. Accidents potentially releasing large amounts of fission products can be ruled out by characteristics of the designs 2. Plant engineered features (and the containment system in particular) are able to drastically mitigate the radioactive releases under all conceivable scenarios. 3. A realistic approach to the consequence evaluation can reduce the expected consequences to effects below any concern. Unfortunately no one single approach is either technically feasible or justified in a perspective of defense in depth and only a mix of them may provide the necessary conditions. It appears that most or all proposed ALWR designs address the technical issues, whose solutions are the bases to eliminate the need for a number of protective actions (evacuation, relocation, sheltering, iodine tablets administration, etc.) even in the case of a severe accident. Some designs are mainly oriented to prevent the need for short term protective actions; they credit simplified Emergency Plans or the capabilities of existing civil protection organizations for public relocation in the long term, if needed. Others take also into account the overall releases to exclude or minimize public relocation and land contamination. Design targets for population individual doses and for land contamination proposed in Italy are discussed in the paper. It is also shown that these limits, while challenging, appear to be within the reach of the next generation proposed designs currently studied in Italy. (author)

Achieving universal health coverage by 2030 requires that lessons from the Millennium Development Goals must be heeded. The most important lesson is that the workforce underpins every function of the health system, and is the rate-limiting step. The three dimensions that continue to limit the success of the development agenda are availability, distribution and performance of health workers - and the Sustainable Development Goals cannot be achieved without addressing all three. Hence, the traditional response of scaling up supply is inadequate: a paradigm shift is required in the design of systems that can properly identify, train, allocate and retain health workers. © The Author 2016.

Finger crease pattern recognition using Legendre moments and principal component analysis

Science.gov (United States)

Luo, Rongfang; Lin, Tusheng

2007-03-01

The finger joint lines defined as finger creases and its distribution can identify a person. In this paper, we propose a new finger crease pattern recognition method based on Legendre moments and principal component analysis (PCA). After obtaining the region of interest (ROI) for each finger image in the pre-processing stage, Legendre moments under Radon transform are applied to construct a moment feature matrix from the ROI, which greatly decreases the dimensionality of ROI and can represent principal components of the finger creases quite well. Then, an approach to finger crease pattern recognition is designed based on Karhunen-Loeve (K-L) transform. The method applies PCA to a moment feature matrix rather than the original image matrix to achieve the feature vector. The proposed method has been tested on a database of 824 images from 103 individuals using the nearest neighbor classifier. The accuracy up to 98.584% has been obtained when using 4 samples per class for training. The experimental results demonstrate that our proposed approach is feasible and effective in biometrics.

"Girls need to behave like girls you know": the complexities of applying a gender justice goal within sexuality education in South African schools.

Science.gov (United States)

Ngabaza, Sisa; Shefer, Tamara; Macleod, Catriona Ida

2016-11-01

Sexuality education, as a component within the Life Orientation (LO) programme in South African schools, is intended to provide young people with knowledge and skills to make informed choices about their sexuality, their own health and that of others. Key to the programme are outcomes relating to power, power relations and gender. In this paper, we apply a critical gender lens to explore the ways in which the teaching of sexuality education engages with larger goals of gender justice. The paper draws from a number of ethnographic studies conducted at 12 South African schools. We focus here on the data collected from focus group discussions with learners, and semi-structured interviews with individual learners, principals and Life Orientation (LO) teachers. The paper highlights the complexities of having gender justice as a central goal of LO sexuality education. Teaching sexuality education is reported to contradict dominant community values and norms. Although some principals and school authorities support gender equity and problematize hegemonic masculinities, learners experience sexuality education as upholding normative gender roles and male power, rather than challenging it. Teachers rely heavily on cautionary messages that put more responsibility for reproductive health on female learners, and use didactic, authoritative pedagogical techniques, which do not acknowledge young people's experience nor facilitate their sexual agency. These complexities need to be foregrounded and worked with systematically if the goal of gender justice within LO is to be realised. Copyright © 2016 Elsevier Inc. All rights reserved.

Local Prediction Models on Mid-Atlantic Ridge MORB by Principal Component Regression

Ling, X.; Snow, J. E.; Chin, W.

2017-12-01

The isotopic compositions of the daughter isotopes of long-lived radioactive systems (Sr, Nd, Hf and Pb ) can be used to map the scale and history of mantle heterogeneities beneath mid-ocean ridges. Our goal is to relate the multidimensional structure in the existing isotopic dataset with an underlying physical reality of mantle sources. The numerical technique of Principal Component Analysis is useful to reduce the linear dependence of the data to a minimum set of orthogonal eigenvectors encapsulating the information contained (cf Agranier et al 2005). The dataset used for this study covers almost all the MORBs along mid-Atlantic Ridge (MAR), from 54oS to 77oN and 8.8oW to -46.7oW, including replicating the dataset of Agranier et al., 2005 published plus 53 basalt samples dredged and analyzed since then (data from PetDB). The principal components PC1 and PC2 account for 61.56% and 29.21%, respectively, of the total isotope ratios variability. The samples with similar compositions to HIMU and EM and DM are identified to better understand the PCs. PC1 and PC2 are accountable for HIMU and EM whereas PC2 has limited control over the DM source. PC3 is more strongly controlled by the depleted mantle source than PC2. What this means is that all three principal components have a high degree of significance relevant to the established mantle sources. We also tested the relationship between mantle heterogeneity and sample locality. K-means clustering algorithm is a type of unsupervised learning to find groups in the data based on feature similarity. The PC factor scores of each sample are clustered into three groups. Cluster one and three are alternating on the north and south MAR. Cluster two exhibits on 45.18oN to 0.79oN and -27.9oW to -30.40oW alternating with cluster one. The ridge has been preliminarily divided into 16 sections considering both the clusters and ridge segments. The principal component regression models the section based on 6 isotope ratios and PCs.

2012-01-01

The overall purpose of the Technical Meeting was to recognize and analyse the implications of the accident occurred at the Fukushima Dai-ichi Nuclear Power Station on current and future fast neutron systems design and operation. The aim was to provide a global forum for discussing the principal lessons learned from this event, and thus to review safety principles and characteristics of existing and future fast neutron concepts, especially in relation with extreme natural events which potentially may lead to severe accident scenarios. The participants also presented and discussed innovative technical solutions, design features and countermeasures for design extension conditions - including earthquakes, tsunami and other extreme natural hazards - which can enhance the safety level of existing and future fast neutron systems. Furthermore, the meeting gave the opportunity to present advanced methods for the evaluation of the robustness of plants against design extension conditions. Another important goal of this TM was to discuss how to harmonize safety approaches and goals for next generation’s fast reactors. Finally, the meeting was intended to identify areas where further research and development in nuclear safety, technology and engineering in the light of the Fukushima accident are needed. In the frame of the implementation of its Nuclear Safety Action Plan endorsed by all Member States, the IAEA will consider these areas as potential technical topics for new Coordinated Research Projects, to be launched in the near future

Advanced Neutron Source radiological design criteria

The operation of the proposed Advanced Neutron Source (ANS) facility will present a variety of radiological protection problems. Because it is desired to design and operate the ANS according to the applicable licensing standards of the Nuclear Regulatory Commission (NRC), it must be demonstrated that the ANS radiological design basis is consistent not only with state and Department of Energy (DOE) and other usual federal regulations, but also, so far as is practicable, with NRC regulations and with recommendations of such organizations as the Institute of Nuclear Power Operations (INPO) and the Electric Power Research Institute (EPRI). Also, the ANS radiological design basis is in general to be consistent with the recommendations of authoritative professional and scientific organizations, specifically the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). As regards radiological protection, the principal goals of DOE regulations and guidance are to keep occupational doses ALARA [as low as (is) reasonably achievable], given the current state of technology, costs, and operations requirements; to control and monitor contained and released radioactivity during normal operation to keep public doses and releases to the environment ALARA; and to limit doses to workers and the public during accident conditions. Meeting these general design objectives requires that principles of dose reduction and of radioactivity control by employed in the design, operation, modification, and decommissioning of the ANS. The purpose of this document is to provide basic radiological criteria for incorporating these principles into the design of the ANS. Operations, modification, and decommissioning will be covered only as they are affected by design

Full Text Available This research aims to determine the manner of school principals regarding knowledge managementin primary school education. The research is a subjective one conducted in general scanning method. Personal informationform and five-likert scale are the main means in which data was collected. During the data collection stage, school principalswere requested to provide information about the way in which they obtain, share, process, evaluate knowledge, take decisionand analyze problems within the scope of knowledge management. In the virtue of the data acquired, the research shows that;the school principals obtain knowledge by attending meetings with teachers, making personal observation, their personalexperience and online resources. Regarding the sharing of knowledge, the research shows the principals always shareknowledge with their assistant principals and teachers; in using of knowledge, decision making and analyzing problemsresearch also shows that principals take decisions in co-operation with assistant principals and teachers. Last but not least,research shows that in storing the knowledge principals mainly use computers and traditional filing techniques. Seminarsshould be organized periodically by specialists with respect to acquiring, sharing, using and also filling knowledge followingdecision-making in order for school administrators to keep abreast of the latest developments in knowledge management

Music and Video Gaming during Breaks: Influence on Habitual versus Goal-Directed Decision Making.

Full Text Available Different systems for habitual versus goal-directed control are thought to underlie human decision-making. Working memory is known to shape these decision-making systems and their interplay, and is known to support goal-directed decision making even under stress. Here, we investigated if and how decision systems are differentially influenced by breaks filled with diverse everyday life activities known to modulate working memory performance. We used a within-subject design where young adults listened to music and played a video game during breaks interleaved with trials of a sequential two-step Markov decision task, designed to assess habitual as well as goal-directed decision making. Based on a neurocomputational model of task performance, we observed that for individuals with a rather limited working memory capacity video gaming as compared to music reduced reliance on the goal-directed decision-making system, while a rather large working memory capacity prevented such a decline. Our findings suggest differential effects of everyday activities on key decision-making processes.
