    development of the company. The accounting information is the raw material for the decisional process. The accounting decisions lead to elaborating all the other types of decisions that help achieving the main goal of the management: continuing the activity. In our oppinion the informational resources of an entity can be part of the asset, the economic information being a precious resource. If used efficiently it can be used to achieve the goals. Any business idea, designing a new concept or tranzaction, have one thing as base: information.

  2. QUALITY OF ACCOUNTING INFORMATION TO OPTIMIZE THE DECISIONAL PROCESS

    Full Text Available This article provides information on business and therefore need managers to obtain information relevant accounting, reliable, clear, accurate and lowest costs to optimize decision making. This need derives from the current economic environment. The survival of organizations in a competitive environment, to which they must adapt, is conditioned by obtaining accounting information which should be qualitative, opportune, vital, and in a short time. This information is related to patrimony, analytical results, the market (dynamics, dimensions, and structure, and relationships with business partners, competitors, suppliers. Therefore focus more intensely on the quality of accounting information. Definition of quality of accounting information but leave the boundaries and features of accounting communication process and aims to determine \\\\\\"quality criteria\\\\\\" or \\\\\\"qualitative characteristics\\\\\\" to develop a measurement tool. Note that the reviewliterature was found that the normalization and accounting dotrine, criteria for definition of quality of accounting infornation are not identical, their selection and ranking is different. Theory and practice also identifies the fact that information itself is worthless. Instead it is valuable once it is used in a decisional process. Thus, the economic value of the accounting information depends on the earnings obtained after making a decision, diminished by information cost. To be more specific, it depends on the table or on the implemented decision tree, on the informational cost and on the optimal condition established by the decision maker (due to the fact that producing accounting information implies costs which are often considerable and profits arise only form shares. The problem of convergence between content and interpretation of information sent by users also take, and the quality of information to be intelligible. In this case, those who use, say users should have sufficient

    Researchers have used several composite face paradigms to assess holistic processing of faces. In the selective attention paradigm, participants decide whether one face part (e.g., top) is the same as a previously seen face part. Their judgment is affected by whether the irrelevant part of the test face is the same as or different than the…

    Studies show adjuvant endocrine therapy increases survival and decreases risk of breast cancer recurrence for hormone receptor-positive tumors. Yet studies also suggest that adherence rates among women taking this therapy may be as low as 50% owing largely to adverse side effects. Despite these rates, research on longitudinal patient decision making regarding this therapy is scant. We sought to map the decision-making process for women considering and initiating adjuvant endocrine therapy, paying particular attention to patterns of uncertainty and decisional change over time. A longitudinal series of semistructured interviews conducted at a multispecialty health care organization in Northern California with 35 newly diagnosed patients eligible for adjuvant endocrine therapy were analyzed. Analysis led to the identification and indexing of 3 new decision-making constructs-decisional phase, decisional direction, and decisional resolve-which were then organized using a visual matrix and examined for patterns characterizing the decision-making process. Our data reveal that most patients do not make a single, discrete decision to take or not take hormone therapy but rather traverse multiple decisional states, characterized by 1) phase, 2) direction, and 3) strength of resolve. Our analysis tracks these decisional states longitudinally using a grayscale-coded matrix. Our data show that decisional resolve wavers not just when considering therapy, as the existing concept of decisional conflict suggests, but even after initiating it, which may signal future decisions to forgo therapy. Adjuvant endocrine therapy, like other chronic care decisions, has a longer decision-making process and implementation period. Thus, theoretical, empirical, and clinical approaches should consider further exploring the new concept and measurement of decisional resolve, as it may help to improve subsequent medication adherence. © The Author(s) 2016.

    The purpose of the present study was to investigate the effect of mastication on Go/No-go decisional processing using event-related potentials (ERPs). Thirteen normal subjects underwent seven sessions of a somatosensory Go/No-go paradigm for approximately 4min; Pre, and Post 1, 2, 3, 4, 5, and 6. The Control condition included the same seven sessions. The RT and standard deviation were recorded, and the peak amplitude and latency of the N140 and P300 components were analyzed. The RT was significantly shorter in Mastication than in Control at Post 1-3 and 4-6. The peak latency of N140 was earlier in Mastication than in Control at Post 4-6. The latency of N140 was shortened by repeated sessions in Mastication, but not by those in Control. The peak latency of P300 was significantly shorter in Mastication than in Control at Post 4-6. The peak latency of P300 was significantly longer in Control with repeated sessions, but not in Mastication. These results suggest that mastication may influence response execution processing in Go trials, as well as response inhibition processing in No-go trials. Mastication accelerated Go/No-go decisional processing in the human brain. Copyright © 2015 International Federation of Clinical Neurophysiology. Published by Elsevier Ireland Ltd.

    2013-06-01

    Full Text Available Having an increased complexity, the internationalization process of small and medium- sized enterprises (SMEs becomes, in the context of globalization and of the freedom of circulation of goods, services, and capital, a decisive factor of both the evolution of the company and the economic force distribution report on the market. The evolution of the world economic system opened a wide action field for small and medium sized companies, who had to adapt to new rules. The internationalization of SMEs is no longer an option, but it becomes a condition of their existence. A high importance in this process belongs to the way decisions are made, both regarding the target market and the entry option, the way entry barriers are overcome and the promotional techniques in this extended business environment. A synthetic analysis of the decisional factors and process is needed in order to fully and correctly understand the internationalization strategies adopted by SMEs. This paper is built around three major objectives, with the scope of determining the SMEs’ internationalization decisions, as well s the impediments met in the process. The paper contributes to the literature in the field of the internationalization of SMEs through the analysis and interpretation of the results acquired during the study regarding their behavior towards the activity expansion on international markets.

    2012-07-01

    Increases in cell culture titers in existing facilities have prompted efforts to identify strategies that alleviate purification bottlenecks while controlling costs. This article describes the application of a database-driven dynamic simulation tool to identify optimal purification sizing strategies and visualize their robustness to future titer increases. The tool harnessed the benefits of MySQL to capture the process, business, and risk features of multiple purification options and better manage the large datasets required for uncertainty analysis and optimization. The database was linked to a discrete-event simulation engine so as to model the dynamic features of biopharmaceutical manufacture and impact of resource constraints. For a given titer, the tool performed brute force optimization so as to identify optimal purification sizing strategies that minimized the batch material cost while maintaining the schedule. The tool was applied to industrial case studies based on a platform monoclonal antibody purification process in a multisuite clinical scale manufacturing facility. The case studies assessed the robustness of optimal strategies to batch-to-batch titer variability and extended this to assess the long-term fit of the platform process as titers increase from 1 to 10 g/L, given a range of equipment sizes available to enable scale intensification efforts. Novel visualization plots consisting of multiple Pareto frontiers with tie-lines connecting the position of optimal configurations over a given titer range were constructed. These enabled rapid identification of robust purification configurations given titer fluctuations and the facility limit that the purification suites could handle in terms of the maximum titer and hence harvest load.

    Highlights: • Decision-making process of the industry and the environment are evaluated in a game theoretic approach. • Industry and environment are considered as two players to find optimal strategies in governing energy policy. • Industry plays its renewable energy usage strategy. • Environment prefers to execute its protection reflex strategy for survivability and sustainability. • The industry’s insistence on the use of fossil fuels will forward strategy for the environment of uncertainty. - Abstract: Intensive energy consuming industrial sectors are the most important actors on global climate change which natural habitat and the environment faced. In this study, by the scope of energy management, decision-making process of the industry and the environment are evaluated in a game theoretic approach. Industry and environment are considered as two players which have conflicting objectives and try to find optimal strategies in governing energy policy. According to concept of study, while industry tries to maintain the sustainability of production with the strategies of fossil fuel, renewable energies, energy recovery and nuclear energy usage, environment exhibits reactive approach to ensure its sustainability. In the flow of study, players’ strategies are analyzed by using Multi-Criteria Decision Making (MCDM) methods and by calculating performance efficiency values of strategies, game payoff matrix is obtained. Finally, optimal strategies are found for both industry and environment in orienting their energy policy and results are evaluated. According to results of the payoff matrix, the equilibrium point is the cell (2, 1) with the values of 0.5324 and 0.5619. This implies that the environment develops protective reflexes for sustainable nature in case of using renewable energy in industry

    2011-06-01

    Decision makers are influenced by the frame of information such that preferences vary depending on whether survival or mortality data are presented. Research is inconsistent as to whether and how age impacts framing effects. This paper presents two studies that used qualitative analyses of think-aloud protocols to understand how the type of information used in the decision making process varies by frame and age. In Study 1, 40 older adults, age 65 to 89, and 40 younger adults, age 18 to 24, responded to a hypothetical lung cancer scenario in a within-subject design. Participants received both a survival and mortality frame. Qualitative analyses revealed that two main decisional strategies were used by all participants: one strategy reflected a data-driven decisional process, whereas the other reflected an experience-driven process. Age predicted decisional strategy, with older adults less likely to use a data-driven strategy. Frame interacted with strategy to predict treatment choice; only those using a data-driven strategy demonstrated framing effects. In Study 2, 61 older adults, age 65 to 98, and 63 younger adults, age 18 to 30, responded to the same scenarios as in Study 1 in a between-subject design. The results of Study 1 were replicated, with age significantly predicting decisional strategy and frame interacting with strategy to predict treatment choice. Findings suggest that framing effects may be more related to decisional strategy than to age. (c) 2011 APA, all rights reserved.

    2005-08-01

    This document is to report the results of existing seismic data re-processing around Horonobe town, Hokkaido, Japan, which is a part of the Horonobe Underground Research Project. The main purpose of this re-processing is to recognize the subsurface structure of Omagari Fault and fold system around Omagari Fault. The seismic lines for re-processing are TYHR-A3 line and SHRB-2 line, which JAPEX surveyed in 1975. Applying weathering static correction using refraction analysis and noise suppression procedure, we have much enhanced seismic profile. Following information was obtained from seismic re-processing results. TYHR-A3 line: There are strong reflections, dipping to the west. These reflections are corresponding western limb of anticline to the west side of Omagari Fault. SHRB-2 line: There are strong reflections, dipping to the west, at CDP 60-140, while there are reflections, dipping to the east, to the east side of CDP 140. These reflections correspond to the western limb and the eastern limb of the anticline, which is parallel to Omagari FAULT. This seismic re-processing provides some useful information to know the geological structure around Omagari Fault. (author)

  14. Impaired decisional impulsivity in pathological videogamers.

    Directory of Open Access Journals (Sweden)

    Michael A Irvine

    Full Text Available Pathological gaming is an emerging and poorly understood problem. Impulsivity is commonly impaired in disorders of behavioural and substance addiction, hence we sought to systematically investigate the different subtypes of decisional and motor impulsivity in a well-defined pathological gaming cohort.Fifty-two pathological gaming subjects and age-, gender- and IQ-matched healthy volunteers were tested on decisional impulsivity (Information Sampling Task testing reflection impulsivity and delay discounting questionnaire testing impulsive choice, and motor impulsivity (Stop Signal Task testing motor response inhibition, and the premature responding task. We used stringent diagnostic criteria highlighting functional impairment.In the Information Sampling Task, pathological gaming participants sampled less evidence prior to making a decision and scored fewer points compared with healthy volunteers. Gaming severity was also negatively correlated with evidence gathered and positively correlated with sampling error and points acquired. In the delay discounting task, pathological gamers made more impulsive choices, preferring smaller immediate over larger delayed rewards. Pathological gamers made more premature responses related to comorbid nicotine use. Greater number of hours played also correlated with a Motivational Index. Greater frequency of role playing games was associated with impaired motor response inhibition and strategy games with faster Go reaction time.We show that pathological gaming is associated with impaired decisional impulsivity with negative consequences in task performance. Decisional impulsivity may be a potential target in therapeutic management.

    Decisional conflict is a state of uncertainty about the best treatment option among competing alternatives and is common among adult patients who are inadequately involved in the health decision making process. In pediatrics, research shows that many parents are insufficiently involved in decisions about their child's health. However, little is known about parents' experience of decisional conflict. We explored parents' perceived decision making involvement and its association with parents' decisional conflict. We conducted a descriptive survey study in a pediatric tertiary care hospital. Our survey was guided by validated decisional conflict screening items (i.e., the SURE test). We administered the survey to eligible parents after an ambulatory care or emergency department consultation for their child. Four hundred twenty-nine respondents were included in the analysis. Forty-eight percent of parents reported not being offered treatment options and 23% screened positive for decisional conflict. Parents who reported being offered options experienced less decisional conflict than parents who reported not being offered options (5% vs. 42%, p conflict after their clinical consultation. Involving parents in the decision making process might reduce their risk of decisional conflict. Evidence based interventions that support parent decision making involvement, such as shared decision making, should be evaluated and implemented in pediatrics as a strategy to reduce parents' decisional conflict.

    Lucena, Marcela Adriana da Silva; Bezerra, Adriana Falangola Benjamin

    2012-09-01

    This study addresses mental health and, based on a conceptual review, offers considerations on the management of deinstitutionalization processes regarding individuals interned in long-stay psychiatric institutions. Elements concerning asylum formation and logic are discussed, along with the mechanisms necessary for the effective change in paradigm and practices, with deinstitutionalization and psychosocial rehabilitation as the core issues. Reflections are offered regarding management actions committed to the psychosocial model, linking such actions to the application of the components of care and going beyond the articulation of the tools of mental health policy. Theoretical reflection offers suggestions referring to the qualification processes of mental health professionals, deinstitutionalization in the management of the Unified Health System and tripartite action with co-accountability in actions and financing. The final considerations recognize the bureaucratic obstacles in the public realm and propose facing these challenges as a management challenge, along with processes of change that can radically commit to the lives of people, thereby broadening the discussion to the ethical realm.

    Attention-deficit/hyperactivity disorder (ADHD) is associated with performance deficits across a broad range of tasks. Although individual tasks are designed to tap specific cognitive functions (e.g., memory, inhibition, planning, etc.), these deficits could also reflect general effects related to either inefficient or impulsive information processing or both. These two components cannot be isolated from each other on the basis of classical analysis in which mean reaction time (RT) and mean accuracy are handled separately. Seventy children with a diagnosis of combined type ADHD and 50 healthy controls (between 6 and 17 years) performed two tasks: a simple two-choice RT (2-CRT) task and a conflict control task (CCT) that required higher levels of executive control. RT and errors were analyzed using the Ratcliff diffusion model, which divides decisional time into separate estimates of information processing efficiency (called "drift rate") and speed-accuracy tradeoff (SATO, called "boundary"). The model also provides an estimate of general nondecisional time. Results were the same for both tasks independent of executive load. ADHD was associated with lower drift rate and less nondecisional time. The groups did not differ in terms of boundary parameter estimates. RT and accuracy performance in ADHD appears to reflect inefficient rather than impulsive information processing, an effect independent of executive function load. The results are consistent with models in which basic information processing deficits make an important contribution to the ADHD cognitive phenotype.

  20. Signal processing issues in reflection tomography

    Science.gov (United States)

    Cadalli, Nail

    2001-12-01

    This dissertation focuses on signal modeling and processing issues of the following problems in reflection tomography: synthetic aperture radar (SAR) imaging of a runway and surroundings from an aircraft approaching for landing, acoustic imaging of objects buried in soil, and lidar imaging of underwater objects. The highly squinted geometry of runway imaging necessitates the incorporation of wavefront curvature into the signal model. We investigate the feasibility of using the wavenumber-domain (ω - k) SAR inversion algorithm, which models the actual curvature of the wavefront, for runway imaging. We demonstrate the aberrations that the algorithm can produce when the squint angle is close to 90° and show that high-quality reconstruction is still possible provided that the interpolation is performed accurately enough, which can be achieved by increasing the temporal sampling rate. We compare the performance with that of a more general inversion method (GIM) that solves the measurement equation directly. The performances of both methods are comparable in the noise- free case. Being inherently robust to noise, GIM produces superior results in the noisy case. We also present a solution to the left-right ambiguity of runway imaging using interferometric processing. In imaging of objects buried in soil, we pursue an acoustic approach primarily for detection and imaging of cultural artifacts. We have developed a mathematical model and associated computer software in order to simulate the signals acquired by the actual experimental system, and a bistatic SAR-type algorithm for reconstruction. In the reconstructions from simulated data, objects were detectable, but near-field objects suffered from shifts and smears. To account for wavefront curvature, we formulated processing of the simulated data using the 3-D version of the monostatic ω - k algorithm. In lidar imaging of underwater objects, we formulate the problem as a 3-D tomographic reconstruction problem. We have

Employing a 200-ms-long broadband noise burst as input signal, the critical delay separating these two binaural phenomena was found to be 7–10 ms. It was suggested that the critical delay refers to a temporal window that is employed......, resulting in a critical delay of about 2–3 ms for 20-ms-long stimuli. Hence, for very short stimuli the temporal window or critical delay exhibits values similar to the auditory temporal resolution as, for instance, observed in gap-detection tasks. It is suggested that the larger critical delay observed...

  4. On risk and decisional capacity.

    Checkland, D

    2001-02-01

    Limits to paternalism are, in the liberal democracies, partially defined by the concepts of decision-making capacity/incapacity (mental competence/incompetence). The paper is a response to Ian Wilks's (1997) recent attempt to defend the idea that the standards for decisional capacity ought to vary with the degree of risk incurred by certain choices. Wilks's defense is based on a direct appeal to the logical features of examples and analogies, thus attempting to by-pass earlier criticisms (e.g., Culver & Gert, 1990) of risk-based standards. Wilks's argument is found wanting on the grounds that he misconstrues the logic of such capacity, especially in accounting for conceptual and pragmatic ties with issues of decisional authority. A diagnosis is offered as to the source of Wilks's error (the assumption that mental competence is a species of wider genus of "competence"), and an alternative way of accounting for risk within the predominant contemporary legal framework is sketched.

    Full Text Available The principle of decisional transparency is one of the principles of good administration, fundamental principles of public administration and it is enshrined in the law of many European Union member states, including our country. In their work the public authorities must show transparency reflected by the active involvement of citizens in administrative decision as its primary beneficiary. The citizen information, consultation and his stimulation to participate actively in the elaboration of draft normative acts for their preparation and before that by bringing them to public knowledge, are tasks of the public authorities which exceed the limit of the obligations imposed by internal rules and are significant efforts to modernize the public administration and rallying to the administrative structures.

    The purpose of this study was to examine decision-making among women considering antidepressant medication use in pregnancy. Decisional conflict was assessed using the Decisional Conflict Scale (DCS) among pregnant women considering antidepressant medication treatment (N = 40). Overall DCS and subscale scores were compared between women who were antidepressant users and non-users. Semi-structured interviews (N = 10) explored barriers and facilitators of decision-making. Twenty-one women (52 %) had moderate or high decisional conflict (DCS ≥ 25). Overall DCS scores did not differ between groups, but antidepressant use was associated with feeling more adequately informed (subscale mean 17.5, SD 17.9 vs. 42.1, SD 23.8, p = 0.001) and clear about values (subscale mean 16.7, SD 15.1 vs. 29.8, SD 24.0, p = 0.043). Barriers to decision-making were (1) difficulty weighing maternal versus infant health, (2) lack of high quality information, (3) negative external influences, and (4) emotional reactions to decision-making. Facilitators were (1) interpersonal supports, (2) accessible subspecialty care, and (3) severe depressive symptoms. Many pregnant women facing decisions regarding antidepressant medication use experience decisional conflict. Interventions that provide accurate information, assistance with weighing risks and benefits of treatment, management of problematic external influences, and emotional support may reduce decisional conflict and facilitate the decision-making process.

    The objective of this qualitative, exploratory-descriptive study was to analyze the group process of a nursing team at Hospital de Clínicas de Porto Alegre (HCPA), under the light of Pichon-Rivière's Operative Group Theory. Data collection took place in 2008, using a semi-structured questionnaire and focal group. The group work concept is one of the four categories that resulted from the study, and is the object of approach in the present article. It was found that the knowledge about the group process must be shared, disseminated and discussed since the undergraduate studies and developed across the professional career. As the team learns and is able to identify the main indicators of the group process, it becomes possible to improve operatively, considering not only the outcomes but mainly the course covered until achieving the goal, aiming at group learning.

    for the two RMTs, it is shown that forward masking effects only have a significant effect on reflection masking for delays above 7–10 ms. Moreover, binaural mechanisms were revealed which deteriorate auditory detection of test reflections for delays below 7–10 ms and enhance detection for larger delays....... The monaural and binaural processes that may underlie reflection masking are discussed in terms of auditory-modelling concepts....

  17. Decisional enhancement and autonomy: public attitudes towards overt and covert nudges

    Directory of Open Access Journals (Sweden)

    Gidon Felsen

    2013-05-01

    Full Text Available Ubiquitous cognitive biases hinder optimal decision making. Recent calls to assist decision makers in mitigating these biases---via interventions commonly called ``nudges''---have been criticized as infringing upon individual autonomy. We tested the hypothesis that such ``decisional enhancement'' programs that target overt decision making---i.e., conscious, higher-order cognitive processes---would be more acceptable than similar programs that affect covert decision making---i.e., subconscious, lower-order processes. We presented respondents with vignettes in which they chose between an option that included a decisional enhancement program and a neutral option. In order to assess preferences for overt or covert decisional enhancement, we used the contrastive vignette technique in which different groups of respondents were presented with one of a pair of vignettes that targeted either conscious or subconscious processes. Other than the nature of the decisional enhancement, the vignettes were identical, allowing us to isolate the influence of the type of decisional enhancement on preferences. Overall, we found support for the hypothesis that people prefer conscious decisional enhancement. Further, respondents who perceived the influence of the program as more conscious than subconscious reported that their decisions under the program would be more ``authentic''. However, this relative favorability was somewhat contingent upon context. We discuss our results with respect to the implementation and ethics of decisional enhancement.

  18. Reflection Positive Stochastic Processes Indexed by Lie Groups

    Jorgensen, Palle E. T.; Neeb, Karl-Hermann; Ólafsson, Gestur

    2016-06-01

    Reflection positivity originates from one of the Osterwalder-Schrader axioms for constructive quantum field theory. It serves as a bridge between euclidean and relativistic quantum field theory. In mathematics, more specifically, in representation theory, it is related to the Cartan duality of symmetric Lie groups (Lie groups with an involution) and results in a transformation of a unitary representation of a symmetric Lie group to a unitary representation of its Cartan dual. In this article we continue our investigation of representation theoretic aspects of reflection positivity by discussing reflection positive Markov processes indexed by Lie groups, measures on path spaces, and invariant gaussian measures in spaces of distribution vectors. This provides new constructions of reflection positive unitary representations.

    Tom Andersen and his pioneering work with reflecting conservations has had a lasting influence on the field of family therapy and mental health more broadly. Most family therapists are familiar with his contributions related to reflecting teams; however, fewer are familiar with his conceptualization of reflecting processes, which offer practical ways to approach therapeutic conversations to address challenging problems. This article provides a brief history of Andersen's career and reviews four key elements of his approach, including: (a) his way of being in relationship, (b) appropriately unusual comments, (c) inner and outer dialogs, and (d) ethics of dialogical relating. Finally, this article introduces readers to the context of the video that will be analyzed in the articles that follow in this special section. © 2018 American Association for Marriage and Family Therapy.

  10. LA PREDECIBILIDAD DE LAS DECISIONES JUDICIALES

    2009-01-01

    Full Text Available El tema que estudio es la predecibilidad de las decisiones judiciales, ligada a los valores de la libertad, la seguridad y la igualdad. El punto de partida es el de que el principio jurisdiccional que guía la actividad de los jueces es ejercer la garantía de cierre del sistema mediante la corrección de los márgenes de desviación e ilegitimidad jurídicas en las que se hubiera podido incurrir. Desde esta perspectiva, me ocupo del marco en el que se ha de construir la teoría y la práctica de la predecibilidad de tales decisiones dentro de un Estado de Derecho, y del juego concatenado de los valores indicados. Para analizar el juego, me adentro en la cuestión de la motivación de las sentencias, la discrecionalidad judicial, los elementos y significados de la seguridad jurídica y los precedentes; profundizando en el tratamiento dado a la predecibilidad del Derecho por el realismo jurídico norteamericano, especialmente por Frank y Llewellyn. En general, se advierte que los cambios que sufre el modelo aplicativo del Derecho rompen con la concepción del estricto formalismo, creándose espacios relacionados con fines y estrategias no jurídicas. Por consiguiente, se comprende que tenía razón el realismo jurídico norteamericano a la hora de conceptuar el Derecho como realidad que sufre un cambio incesante, apoyado en la actividad judicial creativa. En este sentido, queda patente que no se produce sólo por el legislador, sino que también toma parte el juez. Su creación se reenvía a la interpretación de la norma aplicable y a que la norma particular en la que deriva la decisión no es efecto de la lógica.The issue addressed in this study is the predictability of judicial decisions, linked to the values of liberty, the feeling of security it affords people, and equality.

  13. Reflections on the Writing Process: Perspectives from Recent Hindi Novels

    Full Text Available Patricia Waugh defined metafiction as ‘fictional writing which self-consciously and systematically draws attention to its status as an artefact in order to pose questions about the relationship between fiction and reality’ . Metafictional works, she suggested, are those which ‘explore a theory of writing fiction through the practice of writing fiction’. They are characterised by a tendency to self-reflexivity or, in other words, by a tendency to call attention to the writing process itself. In actual fact, even in dedicated critical works, it is not easy to find a clear and all-encompassing definition of metafiction. Generally, various types of texts are mentioned under this term: texts recounting their origin and birth, dealing with the history of narrative, recounting stories of writers. Metafiction is generally considered an important feature of postmodern literature. In the postmodern era pure realistic writing is perceived as a limitation and an unsuitable device to render the complexity of the contemporary world. As Baudrillard said, we no longer live in a world made of unequivocal meanings, we live in a world of signs. In this context authors, by reflecting on the writing process, foreground the fictional nature of their narratives. Because of this, the role of metafiction (which obviously cannot be considered as an innovation introduced by postmodernism has become predominant in the postmodern era. Metafiction can follow different paths to reach its aims: its experimental component can be evident and radical or can be limited to a few pages or lines, without unduly affecting the perception of the story. In some cases, the reader will find no reflections on the structure or on the textual functions of the novel, but on its artistic and intellectual meaning. Within the history of Hindi literature (referring here to Khari Boli Hindi only probably the most famous example of metafictional novel is Suraj ka Satvan Ghoda (The Sun

The present research aimed at analyzing the determinants of decisional procrastination among undergraduate students and at assessing a path model in which self regulated learning strategies mediated the relationship between metacognitive beliefs about procrastination and decisional procrastination. 273 students from Southern Italy filled out a questionnaire composed by: the socio-demographic section, the Metacognitive Beliefs About Procrastination Questionnaire, the procrastination subscale of the Melbourne Decision Making Questionnaire, and the Anxiety, the Time Management, and the Information Processing subscales of the Learning and Study Strategies Inventory. Results showed that the relationship between negative and positive metacognitive beliefs about procrastination and decisional procrastination was mediated only by time management and anxiety. Such findings underlined the crucial role played by learning strategies in predicting the tendency to delay decisional situations and in mediating the relationship between metacognitive beliefs about procrastination and decisional procrastination.

    Shirren, S; Phillips, J G

    2011-10-01

    To understand the use of technology to support interpersonal interaction, a theory of decisional style was applied to email use within the workplace. Previous research has used self-report and rating scales to address employee email behaviours, but this falls short of management's capability to monitor the actual behaviour. Thirty-nine employed individuals completed a five-day communication diary recording their actual behaviour upon receiving personal and work-related emails as well as the Melbourne Decision Making Questionnaire and the Depression Anxiety Stress Scales. It was found that vigilant individuals were more likely to use email in an efficient manner by deleting personal email and being less likely to open email later. Procrastinators, buckpassers and people experiencing high levels of negative affect were all more likely to delay dealing with email, which could be viewed as dealing with email in a less efficient manner. STATEMENT OF RELEVANCE: This work offers insights as to how people receive and process emails and is thus relevant to the development and implementation of collaborative technologies. Whilst other studies use individual's self-reports, this study uses a more accurate communication diary. Decisional style can predict the monitoring and response to electronic communication.

    Full Text Available This study attempted to investigate decisional autonomy in Turkish adolescents from 12 to 18 years. The Perspectives on Adolescent Decision Making (PADM questionnaire was administered to 372 middle class adolescents who attend middle and high schools and to their parents. The PADM assess if adolescents decide for themselves, or parents impose restrictions or adolescents and parents have arguments about the topic. MANOVA analyzes were used. Results showed that affirmative answers increased with age. From adolescent and parents' perspectives adolescent decisional autonomy grows with age, parental control decreases, conflicts between them tended to decrease, on the perspective of parents. There was minor gender differences: girls have higher level of decisional autonomy; boys experience more conflict. Adolescents' decisional autonomy expectations tended to be higher than those of parents. Fathers' and mothers' perspectives on decisional autonomy were very similar. The results support the new family model proposed by Kaðýtçýbaþý.

    The Magicote C process developed by S.M. Thompsen was evaluated for use in applying an antireflective coating to the cover plates of solar panels. The process uses a fluosilicic acid solution supersaturated with silica at elevated temperature to selectively attack the surface of soda-lime glass cover plates and alter the physical and chemical composition of a thin layer of glass. The altered glass layer constitutes an antireflective coating. The process produces coatings of excellent optical quality which possess outstanding resistance to soiling and staining. The coatings produced are not resistant to mechanical abrasion and are attacked to some extent by glass cleansers. Control of the filming process was found to be difficult.

    Recent research demonstrated structural overlap between reward and self processing, but the functional relationship that explains how self processing influences reward processing remains unclear. The present study used an experimentally constrained reflection task to investigate whether individuals' outcome evaluations in a gambling task are modulated by task-unrelated self- and other-reflection processes. The self- and other-reflection task contained descriptions of the self or others, and brain event-related potentials (ERPs) were recorded while 16 normal adults performed a gambling task. The ERP analysis focused on the feedback-related negativity (FRN) component. We found that the difference wave of FRN increased in the self-reflection condition compared with the other-reflection condition. The present findings provide direct evidence that self processing can influence reward processing. Copyright © 2015 Elsevier B.V. All rights reserved.

    The development of cancer drugs is time-consuming and expensive. In particular, failures in late-stage clinical trials are a major cost driver for pharmaceutical companies. This puts a high demand on methods that provide insights into the success chances of new potential medicines. In this study, we systematically analyze publication patterns emerging along the drug discovery process of targeted cancer therapies, starting from basic research to drug approval - or failure. We find clear differences in the patterns of approved drugs compared with those that failed in Phase II/III. Feeding these features into a machine learning classifier allows us to predict the approval or failure of a targeted cancer drug significantly better than educated guessing. We believe that these findings could lead to novel measures for supporting decision making in drug development. Copyright © 2016 Elsevier Ltd. All rights reserved.

  9. The Potential of Self-reflection in the Learning Process of Collaborative negotiation Skills

    DEFF Research Database (Denmark)

    Canal, Margarita

    In her doctoral thesis, Margarita Canal explores the value of self-reflection to facilitate the learning process of collaborative negotiation skills as well as how self-reflection as a mental capacity functions. She draws on theories of self-reflection from the higher and management education...... that reflection makes learning evident to both teachers and students. Moreover, the research sheds light on the understanding of reflection as a mental capacity, based on the conceptualization of the six psychic characteristics connected to it, namely: 1) making contact with oneself, 2) connecting to others, 3......) reality perspective, 4) understanding and expressing emotions, 5) balanced narcissism, and 6) change process. This knowledge constitutes a contribution that allows management teachers who use journaling, self-reflection, or learning portfolios to take into account students’ psychic characteristics...

    2016-12-01

    This study systematically examined how experienced Speech-Language Pathologists (SLPs) use the processes of reflection to develop knowledge relevant for practice in the context of head and neck cancer (HNC) rehabilitation. In-depth, semi-structured interviews were conducted with 12 SLPs working in HNC rehabilitation in North America. Grounded theory methodology was adopted for data collection and analysis. The findings inform a preliminary reflective practice model that depicts the processes of reflection used by practitioners interviewed. Nine categories of reflective processes were identified by participant SLPs in terms of the processes of reflection: ongoing questioning, experimenting through trial and error, integrating knowledge from past cases, embracing surprise, thinking out of the box, being in the moment, consulting with colleagues, putting oneself in the patients' shoes, and discerning ethical issues. These findings provide empirical evidence that supports Schön's theory of reflective practice and contribute to knowledge about the ways in which SLPs use processes of reflection in the context of HNC rehabilitation. The findings of this study have implications for how SLPs perceive and consider their role as knowledge-users and knowledge producers in their day-to-day clinical work, as well as for building capacity for reflective practice.

    Full Text Available Founded on practical rationality, this qualitative case study aimed to explore the teaching practice at university, focusing on teacher's reflections and competencies. To this end, teaching practices were described, analyzed, and interpreted. These interactions with students on a course in the pharmacy program, brought about situations involving dilemmas and learning opportunities for problem-solving and decision-making skills. Throughout the study, students were encouraged to use knowledge-in-action, reflection-in-action, and reflection-on-action, and these processes were also experienced by the teacher. Analysis of the records from classroom observation and the interviews with students and the teacher showed the fundamental role of such reflective processes, which led to attainment of the intended objectives. In this sense, the teacher's reflective practice was essential for supporting the application of each curricular component of the course.

    2015-02-01

    A common question in perceptual science is to what extent different stimulus dimensions are processed independently. General recognition theory (GRT) offers a formal framework via which different notions of independence can be defined and tested rigorously, while also dissociating perceptual from decisional factors. This article presents a new GRT model that overcomes several shortcomings with previous approaches, including a clearer separation between perceptual and decisional processes and a more complete description of such processes. The model assumes that different individuals share similar perceptual representations, but vary in their attention to dimensions and in the decisional strategies they use. We apply the model to the analysis of interactions between identity and emotional expression during face recognition. The results of previous research aimed at this problem have been disparate. Participants identified four faces, which resulted from the combination of two identities and two expressions. An analysis using the new GRT model showed a complex pattern of dimensional interactions. The perception of emotional expression was not affected by changes in identity, but the perception of identity was affected by changes in emotional expression. There were violations of decisional separability of expression from identity and of identity from expression, with the former being more consistent across participants than the latter. One explanation for the disparate results in the literature is that decisional strategies may have varied across studies and influenced the results of tests of perceptual interactions, as previous studies lacked the ability to dissociate between perceptual and decisional interactions.

  18. Fall prevention modulates decisional saccadic behaviour in aging

    Full Text Available As society ages and frequency of falls increases in older adults, counteracting motor decline is a challenging issue for developed countries. Physical activity based on aerobic and strength training as well as motor activity based on skill learning both help benefit balance and reduce the risk of falls, as assessed by clinical or laboratory measures. However, how such programs influence motor control is a neglected issue. This study examined the effects of fall prevention (FP training on saccadic control in older adults. Saccades were recorded in twelve participants aged 64-91 years before and after 2.5-month training in FP. Traditional analysis of saccade timing and dynamics was performed together with a quantitative analysis using the LATER model, enabling us to examine the underlying motor control processes. Results indicated that FP reduced the rate of anticipatory and express saccades in inappropriate directions and enhanced that of express saccades in the appropriate direction, resulting in decreased latency and higher left-right symmetry of motor responses. FP reduced within-participant variability of saccade duration, amplitude, and peak velocity. LATER analysis suggested that FP modulates decisional thresholds, extending our knowledge of motor training influence on central motor control. We introduce the TIMER-RIDER model to account for the results.

    A spectral image processing algorithm that allows the illumination of the scene with different illuminants together with the reconstruction of the scene's reflectance is presented. Color checker spectral image and CIE A (warm light 2700 K), D65 (cold light 6500 K) and Cree TW Series LED T8 (4000 K) are employed for scene illumination. Illuminants used in the simulations have different spectra and, as a result of their illumination, the colors of the scene change. The influence of the illuminants on the reconstruction of the scene's reflectance is estimated. Demonstrative images and reflectance showing the operation of the algorithm are illustrated.

    Self-reflection is a tool of instruction that has been used in the science classroom. Research has shown great promise in using video as a learning tool in the classroom. However, the integration of self-reflective practice using video in the general chemistry laboratory to help students develop process skills has not been done. Immediate video feedback and direct instruction were employed in a general chemistry laboratory course to improve students' mastery and understanding of basic and advanced process skills. Qualitative results and statistical analysis of quantitative data proved that self-reflection significantly helped students develop basic and advanced process skills, yet did not seem to influence the general understanding of the science content.

    Learning circles are an enabling process to critically examine and reflect on practices with the purpose of promoting individual and organizational growth and change. The authors adapted and developed a learning circle strategy to facilitate open discourse between registered nurses, clinical leaders, clinical facilitators and students, to critically reflect on practice experiences to promote a positive learning environment. This paper reports on an analysis of field notes taken during a critical reflection process used to create an effective learning community in the workplace. A total of 19 learning circles were conducted during in-service periods (that is, the time allocated for professional education between morning and afternoon shifts) over a 3 month period with 56 nurses, 33 students and 1 university-employed clinical supervisor. Participation rates ranged from 3 to 12 individuals per discussion. Ten themes emerged from content analysis of the clinical learning issues identified through the four-step model of critical reflection used in learning circle discussions. The four-step model of critical reflection allowed participants to reflect on clinical learning issues, and raise them in a safe environment that enabled topics to be challenged and explored in a shared and cooperative manner.

    Full Text Available Background: Dual process models suggest that the development of addictive behaviors is the result of interplay between impulsive and reflective processes, modulated by boundary conditions such as individual or situational factors. Empirical support for this model has been repeatedly demonstrated in adult samples (for a meta-analysis see Rooke, Hine, & Thorsteinsson, 2008. The purpose of this study was to test these processes as they relate to emerging alcohol use in adolescents. Specifically, the interactive effects of several measures of impulsive and reflective processes and working memory capacity are examined as predictors of changes in alcohol use among adolescents. It was expected that measures of reflective processes would better predict changes in alcohol use than measures of impulsive processes. Moreover, it was anticipated that working memory capacity would moderate the relation between alcohol-specific impulsive and reflective processes and changes in adolescent alcohol use. Methods: The sample consisted of 427 adolescents (47.7% male between 12 and 16 years of age (M = 13.96, SD = .78 who reported drinking alcohol at least once. Four measures of impulsive processes were included. Attentional bias for alcohol was assessed with a Visual Probe Test; approach bias toward alcohol was assessed with a Stimulus Response Compatibility Test (SRC; and memory associations with alcohol were assessed with an Implicit Association Test (IAT and a Word Association Test (WAT. Two measures of reflective measures were included: positive and negative expectancies. Working memory capacity was measured using a Self-Ordered Pointing Task (SOPT.Results: Results showed that positive expectancies predicted changes in alcohol use, but this effect was qualified by an interaction with IAT scores. Moreover, SRC scores predicted changes in alcohol use only when negative expectancies were low. Attentional bias and word association scores did not predict changes in

    The information provided in patient-centered care and shared decision-making influences patients' concerns and adherence to treatment. In the decision-making process, patients experience decisional conflict. The Decisional Conflict Scale (DCS) is a 16-item, self-administered questionnaire consisting of 5 subscales developed to assess patients' decisional conflict. This study aimed to develop the Japanese version of the DCS and to clarify the influence of the information provided by pharmacists' on decisional conflict among patients with cancer. We developed the Japanese version of the DCS by using the forward-backward translation method. One hundred patients who were recommended a new chemotherapy regimen were recruited. The psychometric properties of the Japanese DCS, including internal consistency, convergent validity, discriminant validity, and construct validity, were examined. We assessed the decisional conflict of patients before and after the pharmacists' provision of information. Ninety-four patients, predominately female, with an average age of 58.1 years were sampled. The scores on the 5 subscales of the DCS showed high internal consistency (Cronbach's alpha = 0.84-0.96). Multi-trait scaling analysis and cluster analysis showed strong validity. The mean total DCS score decreased significantly from 40.2 to 31.7 after patients received information from the pharmacists (p informed, values clarity, support, and effective decision, also significantly improved (p information was able to decrease decisional conflict among patients with cancer who were recommended a new chemotherapy regimen.

  7. A functional-dynamic reflection on participatory processes in modeling projects.

    2015-12-01

    The participation of nonscientists in modeling projects/studies is increasingly employed to fulfill different functions. However, it is not well investigated if and how explicitly these functions and the dynamics of a participatory process are reflected by modeling projects in particular. In this review study, I explore participatory modeling projects from a functional-dynamic process perspective. The main differences among projects relate to the functions of participation-most often, more than one per project can be identified, along with the degree of explicit reflection (i.e., awareness and anticipation) on the dynamic process perspective. Moreover, two main approaches are revealed: participatory modeling covering diverse approaches and companion modeling. It becomes apparent that the degree of reflection on the participatory process itself is not always explicit and perfectly visible in the descriptions of the modeling projects. Thus, the use of common protocols or templates is discussed to facilitate project planning, as well as the publication of project results. A generic template may help, not in providing details of a project or model development, but in explicitly reflecting on the participatory process. It can serve to systematize the particular project's approach to stakeholder collaboration, and thus quality management.

    2007-11-01

    Resolution of a critical organizational problem requires the use of carefully selected techniques. This is the work of a management consultant: facilitating a business change process in an organizational setting. Here, an account is provided of a practitioner's reflections on one such case study that demonstrates a structure for a business change process. The reflective account highlights certain affective states and social behaviors that were extracted from participants during the business change process. These affective states and social behaviors are mediated by specific neural networks in the brain that are activated during organizational intervention. By breaking down the process into the affective states and social behaviors highlighted, cognitive neuroscience can be a useful tool for investigating the neural substrates of such intervention. By applying a cognitive neuroscience approach to examine organizational change, it is possible to converge on a greater understanding of the neural substrates of everyday social behavior.

    Posiva Oy takes care of the final disposal of spent nuclear fuel in Finland. In year 2001 Olkiluoto was selected for the site of final disposal. Currently construction of the underground research facility, ONKALO, is going on at the Olkiluoto site. The aim of this work was to use two-dimensional reflection seismic processing methods to refraction seismic data collected from the ONKALO area in year 2002, and to locate gently dipping reflectors from the stacked sections. Processing was done using mainly open source software Seismic Unix. After the processing, the most distinct two-dimensional reflectors were picked from seismic sections using visualization environment OpendTect. After picking the features from crossing lines were combined into three-dimensional surfaces. Special attention was given for the detection of possible faults and discontinuities. The surfaces were given coordinates and their orientation was adjusted using a geometric procedure, which corresponds roughly a 3D migration, transferred to 3D presentation utility and compared to available geological information. The advantage of this work is to be able to get three-dimensional reflection seismic results from existing data set at only processing costs. Survey lines are also partly located in ONKALO area where extensive surface seismic surveys may not be possible to perform. The applied processing method was successful in detecting the reflectors. Most significant steps were the refraction and residual statics, and deconvolution. Some distinct reflectors can be seen at times 20-200 ms (vertical depths 50-500 m). The signal gets noisier below 200 ms. Reflectors are best visible as coherent phase between the adjacent traces, but do not raise much above the surrounding noise level. Higher amount of traces to be stacked would emphasis the reflections and their continuity more. Reflectors picked on crossing lines match well to borehole observations (KR4, KR7, KR24 and KR38) of fracture zones, and get

The methodology is based upon the innovativeconcept of capacity margin, established within this work, by which the maximum load that can beconnected to any given point is computed in advance in offline mode. The criteria for finding the maximumload are based on the common requirements of minimum voltage and maximum loading. The proposedmethodology automatically eliminates the possibility of making incorrect decisions associated withconventional filtering techniques. The application of the proposed methodology is illustrated throughvarious examples which use real distribution networks, at both low and medium voltage levels.

  4. NONLINEAR REFLECTION PROCESS OF LINEARLY POLARIZED, BROADBAND ALFVÉN WAVES IN THE FAST SOLAR WIND

    Using one-dimensional numerical simulations, we study the elementary process of Alfvén wave reflection in a uniform medium, including nonlinear effects. In the linear regime, Alfvén wave reflection is triggered only by the inhomogeneity of the medium, whereas in the nonlinear regime, it can occur via nonlinear wave–wave interactions. Such nonlinear reflection (backscattering) is typified by decay instability. In most studies of decay instabilities, the initial condition has been a circularly polarized Alfvén wave. In this study we consider a linearly polarized Alfvén wave, which drives density fluctuations by its magnetic pressure force. For generality, we also assume a broadband wave with a red-noise spectrum. In the data analysis, we decompose the fluctuations into characteristic variables using local eigenvectors, thus revealing the behaviors of the individual modes. Different from the circular-polarization case, we find that the wave steepening produces a new energy channel from the parent Alfvén wave to the backscattered one. Such nonlinear reflection explains the observed increasing energy ratio of the sunward to the anti-sunward Alfvénic fluctuations in the solar wind with distance against the dynamical alignment effect.

  5. Visual Short-Term Memory Activity in Parietal Lobe Reflects Cognitive Processes beyond Attentional Selection.

    Visual short-term memory (VSTM) and attention are distinct yet interrelated processes. While both require selection of information across the visual field, memory additionally requires the maintenance of information across time and distraction. VSTM recruits areas within human (male and female) dorsal and ventral parietal cortex that are also implicated in spatial selection; therefore, it is important to determine whether overlapping activation might reflect shared attentional demands. Here, identical stimuli and controlled sustained attention across both tasks were used to ask whether fMRI signal amplitude, functional connectivity, and contralateral visual field bias reflect memory-specific task demands. While attention and VSTM activated similar cortical areas, BOLD amplitude and functional connectivity in parietal cortex differentiated the two tasks. Relative to attention, VSTM increased BOLD amplitude in dorsal parietal cortex and decreased BOLD amplitude in the angular gyrus. Additionally, the tasks differentially modulated parietal functional connectivity. Contrasting VSTM and attention, intraparietal sulcus (IPS) 1-2 were more strongly connected with anterior frontoparietal areas and more weakly connected with posterior regions. This divergence between tasks demonstrates that parietal activation reflects memory-specific functions and consequently modulates functional connectivity across the cortex. In contrast, both tasks demonstrated hemispheric asymmetries for spatial processing, exhibiting a stronger contralateral visual field bias in the left versus the right hemisphere across tasks, suggesting that asymmetries are characteristic of a shared selection process in IPS. These results demonstrate that parietal activity and patterns of functional connectivity distinguish VSTM from more general attention processes, establishing a central role of the parietal cortex in maintaining visual information. SIGNIFICANCE STATEMENT Visual short-term memory (VSTM) and

    2017-12-01

    A transmission and reflection coupled ultrasonic process tomography has been developed, which is characterized by a proposed dual-mode (DM) reconstruction algorithm, as well as an adaptive search approach to determine an optimal image threshold during the image binarization. In respect of hardware, to improve the accuracy of time-of-flight (TOF) and extend the lowest detection limit of particle size, a cylindrical miniaturized transducer using polyvinylidene fluoride (PVDF) films is designed. Besides, the development of range-gating technique for the identification of transmission and reflection waves in scanning is discussed. A particle system with four iron particles is then investigated numerically and experimentally to evaluate these proposed methods. The sound pressure distribution in imaging area is predicted numerically, followed by the analysis of the relationship between the emitting surface width of transducer and particle size. After the processing of experimental data for effective waveform extraction and fusion, the comparison between reconstructed results from transmission-mode (TM), reflection-mode (RM), and dual-mode reconstructions is carried out and the latter manifests obvious improvements from the blurring reduction to the enhancement of particle boundary.

    To describe the importance of supervisors working together in supporting the learning process of nurse students through reflective caring science supervision. A supervision model has been developed in order to meet the need for interweaving theory and practice. The model is characterized by learning reflection in caring science. A unique aspect of the present project was that the student groups were led by a teacher and a nurse. Data were collected through interviews with the supervisors. The analysis was performed with a phenomenological approach. The results showed that theory and practice can be made more tangible and interwoven by using two supervisors in a dual supervision. The essential structure is built on the constituents 'Reflection as Learning Support', 'Interweaving Caring Science with the Patient's Narrative', 'The Student as a Learning Subject' and 'The Learning Environment of Supervision'. The study concludes that supervision in pairs provides unique possibilities for interweaving and developing theory and practice. The supervision model offers unique opportunities for cooperation, for the development of theory and practice and for the development of the professional roll of nurses and teachers. © 2012 Blackwell Publishing Ltd.

  12. Hippocampal Theta-Gamma Coupling Reflects State-Dependent Information Processing in Decision Making.

    2018-03-20

    During decision making, hippocampal activity encodes information sometimes about present and sometimes about potential future plans. The mechanisms underlying this transition remain unknown. Building on the evidence that gamma oscillations at different frequencies (low gamma [LG], 30-55 Hz; high gamma [HG], 60-90 Hz; and epsilon, 100-140 Hz) reflect inputs from different circuits, we identified how changes in those frequencies reflect different information-processing states. Using a unique noradrenergic manipulation by clonidine, which shifted both neural representations and gamma states, we found that future representations depended on gamma components. These changes were identifiable on each cycle of theta as asymmetries in the theta cycle, which arose from changes within the ratio of LG and HG power and the underlying phases of those gamma rhythms within the theta cycle. These changes in asymmetry of the theta cycle reflected changes in representations of present and future on each theta cycle. Copyright © 2018 The Author(s). Published by Elsevier Inc.

    Controversy has attended the relationship between risk-adjusted mortality and process-of-care. There would be advantage in the establishment, at the data-base level, of global quantitative indices subsuming the diversity of process-of-care. A retrospective, cohort study of patients identified in the Australian and New Zealand Intensive Care Society Adult Patient Database, 1993-2003, at the level of geographic and ICU-level descriptors (n = 35), for both hospital survivors and non-survivors. Process-of-care indices were established by analysis of: (i) the smoothed time-hazard curve of individual patient discharge and determined by pharmaco-kinetic methods as area under the hazard-curve (AUC), reflecting the integrated experience of the discharge process, and time-to-peak-hazard (TMAX, in days), reflecting the time to maximum rate of hospital discharge; and (ii) individual patient ability to optimize output (as length-of-stay) for recorded data-base physiological inputs; estimated as a technical production-efficiency (TE, scaled [0,(maximum)1]), via the econometric technique of stochastic frontier analysis. For each descriptor, multivariate correlation-relationships between indices and summed mortality probability were determined. The data-set consisted of 223129 patients from 99 ICUs with mean (SD) age and APACHE III score of 59.2(18.9) years and 52.7(30.6) respectively; 41.7% were female and 45.7% were mechanically ventilated within the first 24 hours post-admission. For survivors, AUC was maximal in rural and for-profit ICUs, whereas TMAX (>or= 7.8 days) and TE (>or= 0.74) were maximal in tertiary-ICUs. For non-survivors, AUC was maximal in tertiary-ICUs, but TMAX (>or= 4.2 days) and TE (>or= 0.69) were maximal in for-profit ICUs.

    Full Text Available Objective. Activation of semantic networks is indexed by the N400 effect. We used a twin study design to investigate whether N400 effect abnormalities reflect genetic/trait liability or are related to psychopathological processes in schizophrenia. Methods. We employed robust linear regression to compare N400 and behavioral priming effects across 36 monozygotic twin pairs (6 pairs concordant for schizophrenia/schizoaffective disorder, 11 discordant pairs, and 19 healthy control pairs performing a lexical decision task. Moreover, we examined the correlation between Brief Psychiatric Rating Scale (BPRS score and the N400 effect and the influence of medication status on this effect. Results. Regression yielded a significant main effect of group on the N400 effect only in the direct priming condition (p=0.003. Indirect condition and behavioral priming effect showed no significant effect of group. Planned contrasts with the control group as a reference group revealed that affected concordant twins had significantly reduced N400 effect compared to controls, and discordant affected twins had a statistical trend for reduced N400 effect compared to controls. The unaffected twins did not differ significantly from the controls. There was a trend for correlation between reduced N400 effect and higher BPRS scores, and the N400 effect did not differ significantly between medicated and unmedicated patients. Conclusions. Reduced N400 effect may reflect disease-specific processes in schizophrenia implicating frontotemporal brain network in schizophrenia pathology.

    2012-12-01

    Full Text Available Thus far, the sequencing of political reform processes has been discussed on a separate basis in the context of different scientific debates. Existing analysis in macroeconomics and democracy theory focuses on shock-therapeutic versus gradual reform policies, the succession of specific reform steps or the right timing of reforms. An analytical approach to sequences has been elaborated. Theoretical concepts of social change, which refer to path dependence or the punctuated development of historical sequences, have evolved in the context of institutionalist research. The present article summarises the state of research and extends it with conceptual reflections on the motivation of sequential political action, which can then serve as a starting point for differentiation between sequencing processes in further research.

    Full Text Available The essay explains how the inclusion of the security of public policy in the 2008 Constitution of Ecuador as part of the constitutional state of law and justice or “guarantor state” can become a substantial limit for criminal decisionism, which is usually behind the penal policy in Latin America. Thus, the function of this collateral is to eliminate the huge space of discretion in the management of the most sensitive policy of modern state penal policy. However, the guarantee of public policy is not clear in determining the limits of punitive power; therefore, this paper seeks to explore some of the international human rights.

    Objective We explored whether active patient involvement in decision making and greater patient knowledge are associated with better treatment decision making experiences and better quality of life (QOL) among men with clinically localized prostate cancer. Localized prostate cancer treatment decision-making is an advantageous model for studying patient treatment decision-making dynamics as there are multiple treatment options and a lack of empirical evidence to recommend one over the other; consequently, it is recommended that patients be fully involved in making the decision. Methods Men with newly diagnosed clinically localized prostate cancer (N=1529) completed measures of decisional control, prostate cancer knowledge, and their decision-making experience (decisional conflict, and decision-making satisfaction and difficulty) shortly after they made their treatment decision. Prostate cancer-specific QOL was assessed 6-months after treatment. Results More active involvement in decision making and greater knowledge were associated with lower decisional conflict and higher decision-making satisfaction, but greater decision-making difficulty. An interaction between decisional control and knowledge revealed that greater knowledge was only associated with greater difficulty for men actively involved in making the decision (67% of sample). Greater knowledge, but not decisional control predicted better QOL 6-months post-treatment. Conclusion Although men who are actively involved in decision making and more knowledgeable may make more informed decisions, they could benefit from decisional support (e.g., decision-making aids, emotional support from providers, strategies for reducing emotional distress) to make the process easier. Men who were more knowledgeable about prostate cancer and treatment side effects at the time they made their treatment decision may have appraised their QOL as higher because they had realistic expectations about side effects.

    study seeks to evaluate the public-private relationship in the process of decision making in companies, with the objective of analyzing the export process under the perspective of the decisions oriented to the transaction costs management in the company. In short, the research points out that the public-private relationship shows as a result inappropriate environment, tightening the competition on the global scenario. In the case studied the basic parameters around which the attributes are formed, cost and level of service are adversely affected by this relationship. In turn, the institutional environment in Brazil, with regard to port operations, imposes severe transaction costs.RESUMENEn el ámbito de las decisiones de naturaleza microeconómica y de gestión de empresas se observa un creciente reconocimiento de la importancia de las decisiones referentes al transporte, para el desempeño de actividad logística; esto se debe a que ellas asumen trade-offs relevantes con otras funciones y procesos logísticos, como por ejemplo, existencias, almacenamiento y compras, y afectan directamente los resultados de los servicios y costos logísticos. Esto requiere considerar los transportes no como “demanda derivada”, según la tradición neoclásica, sino como variables explicativas de decisiones empresariales. De forma que en el presente artículo se buscó evaluar la relación público privada en la toma de decisiones empresariales, por medio de un estudio de caso, que tuvo por finalidad analizar el proceso de exportación desde la perspectiva de las decisiones empresariales relacionadas con la gestión de los costos de transacción. En resumen, la investigación demuestra que esta relación público privada proyecta un ambiente poco adecuado para la incuestionable exacerbación de la competición en el ámbito global.

    Arweiler and Buchholz [J. Acoust. Soc. Am. 130, 996-1005 (2011)] showed that, while the energy of early reflections (ERs) in a room improves speech intelligibility, the benefit is smaller than that provided by the energy of the direct sound (DS). In terms of integration of ERs and DS, binaural...... listening did not provide a benefit from ERs apart from a binaural energy summation, such that monaural auditory processing could account for the data. However, a diffuse speech shaped noise (SSN) was used in the speech intelligibility experiments, which does not provide distinct binaural cues...... to the auditory system. In the present study, the monaural and binaural benefit from ERs for speech intelligibility was investigated using three directional maskers presented from 90° azimuth: a SSN, a multi-talker babble, and a reversed two-talker masker.

    An apparatus and process are disclosed for removal of a stripe of soft reflective material of uniform width from the surface of a mirror by using a blade having a large included angle to inhibit curling of the blade during the cutting operation which could result in damage to the glass substrate of the mirror. The cutting blade is maintained at a low blade angle with respect to the mirror surface to produce minimal chipping along the cut edge and to minimize the force exerted on the coating normal to the glass surface which could deform the flat mirror. The mirror is mounted in a cutting mechanism containing a movable carriage on which the blade is mounted to provide very accurate straightness of the travel of the blade along the mirror.

    Nursing students on clinical placements as part of their professional training are routinely faced with situations involving ethical conflicts. The initial act of perceiving a situation as causing an ethical dilemma is the result of both the students' personal values, drawn from their culture and families, and of the professional knowledge and values that they have acquired through training and experience. Nursing students' experiences on clinical placements in primary care settings were investigated in order to identify situations that they perceived as involving ethical conflict and describe the elements they took into consideration during their decision-making processes in these situations. The research design was qualitative descriptive case study. Around 50 students from three different intakes to a nursing degree answered a questionnaire and discussed it in focus groups. The study was designed in accordance with the principles guiding research with human beings and was approved by the Human Research Ethics Committee. Synthesised into two principal axes: (a) ethical conflicts in primary care, linked with the domains of working processes, professional nursing ethics and human and social rights and (b) students' decision-making processes - realisation, reflection and intervention. The student nurses saw themselves both as actors and spectators in situations involving ethical problems and demanding moral deliberation, demonstrating the ability to base their arguments soundly. They tended to emphasise the possibilities offered by dialogue and that different ethical values must be respected to find fair solutions to ethical problems. © The Author(s) 2014.

    Modern bioprocesses demand for a careful definition of the critical process parameters (CPPs) already during the early stages of process development in order to ensure high-quality products and satisfactory yields. In this context, online monitoring tools can be applied to recognize unfavorable changes of CPPs during the production processes and to allow for early interventions in order to prevent losses of production batches due to quality issues. Process analytical technologies such as the dielectric spectroscopy or focused beam reflectance measurement (FBRM) are possible online monitoring tools, which can be applied to monitor cell growth as well as morphological changes. Since the dielectric spectroscopy only captures cells with intact cell membranes, even information about dead cells with ruptured or leaking cell membranes can be derived. The following chapter describes the application of dielectric spectroscopy on various virus-infected and non-infected cell lines with respect to adherent as well as suspension cultures in common stirred tank reactors. The adherent mammalian cell lines Vero (African green monkey kidney cells) and hMSC-TERT (telomerase-immortalized human mesenchymal stem cells) are thereby cultured on microcarrier, which provide the required growth surface and allow the cultivation of these cells even in dynamic culture systems. In turn, the insect-derived cell lines S2 and Sf21 are used as examples for cells typically cultured in suspension. Moreover, the FBRM technology as a further monitoring tool for cell culture applications has been included in this chapter using the example of Drosophila S2 insect cells.

    Researchers and quality improvement advocates sometimes use review of chart-documented pain care processes to assess the quality of pain management. Studies have found that primary care providers frequently fail to document pain assessment and management. To assess documentation of pain care processes in an academic primary care clinic and evaluate the validity of this documentation as a measure of pain care delivered. Prospective observational study. 237 adult patients at a university-affiliated internal medicine clinic who reported any pain in the last week. Immediately after a visit, we asked patients to report the pain treatment they received. Patients completed the Brief Pain Inventory (BPI) to assess pain severity at baseline and 1 month later. We extracted documentation of pain care processes from the medical record and used kappa statistics to assess agreement between documentation and patient report of pain treatment. Using multivariable linear regression, we modeled whether documented or patient-reported pain care predicted change in pain at 1 month. Participants' mean age was 53.7 years, 66% were female, and 74% had chronic pain. Physicians documented pain assessment for 83% of visits. Patients reported receiving pain treatment more often (67%) than was documented by physicians (54%). Agreement between documentation and patient report was moderate for receiving a new pain medication (k = 0.50) and slight for receiving pain management advice (k = 0.13). In multivariable models, documentation of new pain treatment was not associated with change in pain (p = 0.134). In contrast, patient-reported receipt of new pain treatment predicted pain improvement (p = 0.005). Chart documentation underestimated pain care delivered, compared with patient report. Documented pain care processes had no relationship with pain outcomes at 1 month, but patient report of receiving care predicted clinically significant improvement. Chart review measures may not accurately

  19. Separation of irradiance and reflectance from observed color images by logarithmical nonlinear diffusion process

    Science.gov (United States)

    Saito, Takahiro; Takahashi, Hiromi; Komatsu, Takashi

    2006-02-01

    The Retinex theory was first proposed by Land, and deals with separation of irradiance from reflectance in an observed image. The separation problem is an ill-posed problem. Land and others proposed various Retinex separation algorithms. Recently, Kimmel and others proposed a variational framework that unifies the previous Retinex algorithms such as the Poisson-equation-type Retinex algorithms developed by Horn and others, and presented a Retinex separation algorithm with the time-evolution of a linear diffusion process. However, the Kimmel's separation algorithm cannot achieve physically rational separation, if true irradiance varies among color channels. To cope with this problem, we introduce a nonlinear diffusion process into the time-evolution. Moreover, as to its extension to color images, we present two approaches to treat color channels: the independent approach to treat each color channel separately and the collective approach to treat all color channels collectively. The latter approach outperforms the former. Furthermore, we apply our separation algorithm to a high quality chroma key in which before combining a foreground frame and a background frame into an output image a color of each pixel in the foreground frame are spatially adaptively corrected through transformation of the separated irradiance. Experiments demonstrate superiority of our separation algorithm over the Kimmel's separation algorithm.

  20. Big-data reflection high energy electron diffraction analysis for understanding epitaxial film growth processes.

    Reflection high energy electron diffraction (RHEED) has by now become a standard tool for in situ monitoring of film growth by pulsed laser deposition and molecular beam epitaxy. Yet despite the widespread adoption and wealth of information in RHEED images, most applications are limited to observing intensity oscillations of the specular spot, and much additional information on growth is discarded. With ease of data acquisition and increased computation speeds, statistical methods to rapidly mine the data set are now feasible. Here, we develop such an approach to the analysis of the fundamental growth processes through multivariate statistical analysis of a RHEED image sequence. This approach is illustrated for growth of La(x)Ca(1-x)MnO(3) films grown on etched (001) SrTiO(3) substrates, but is universal. The multivariate methods including principal component analysis and k-means clustering provide insight into the relevant behaviors, the timing and nature of a disordered to ordered growth change, and highlight statistically significant patterns. Fourier analysis yields the harmonic components of the signal and allows separation of the relevant components and baselines, isolating the asymmetric nature of the step density function and the transmission spots from the imperfect layer-by-layer (LBL) growth. These studies show the promise of big data approaches to obtaining more insight into film properties during and after epitaxial film growth. Furthermore, these studies open the pathway to use forward prediction methods to potentially allow significantly more control over growth process and hence final film quality.

    The results of the investigation of the inelastic interaction of 300-3000 eV electrons with the Ni and Au surfaces by the analysis of absolute reflection electron energy loss spectroscopy (REELS) spectra were described. The present analysis enables the inelastic mean free path (IMFP), surface excitation parameter (SEP) and differential SEP (DSEP) to be obtained simultaneously from an absolute REELS spectrum. The obtained IMFPs for Ni and Au showed a good agreement with those calculated using the TPP-2M predictive equation. The present SEPs determined for Ni and Au were fitted to the Chen's formula describing the dependence of the SEP on the electron energy, and material parameters for Ni and Au in Chen's formula were proposed. The present DESPs were compared with the theoretical results, and a reasonable agreement between the experimentally determined DSEPs and theoretical results was confirmed. The MC modeling of calculating the REELS spectrum, in which energy loss processes due to surface excitations are taken into account, was also described. The IMFP, SEP and DSEP determined by the present absolute REELS analysis were employed to describe energy loss processes by inelastic scattering in the proposed MC simulation. The simulated REELS spectra were found to be in a good agreement with the experimental spectra for both Ni and Au.

  2. Solution-processable MoOx nanocrystals enable highly efficient reflective and semitransparent polymer solar cells

    2016-09-09

    Solution-manufacturing of organic solar cells with best-in-class power conversion efficiency (PCE) will require all layers to be solution-coated without compromising solar cell performance. To date, the hole transporting layer (HTL) deposited on top of the organic bulk heterojunction layer in the inverted architecture is most commonly an ultrathin (<10 nm) metal oxide layer prepared by vacuum-deposition. Here, we show that an alcohol-based nanocrystalline MoOx suspension with carefully controlled nanocrystal (NC) size can yield state of the art reflective and semitransparent solar cells. Using NCs smaller than the target HTL thickness (∼10 nm) can yield compact, pinhole-free films which result in highly efficient polymer:fullerene bulk heterojunction (BHJ) solar cells with PCE=9.5%. The solution processed HTL is shown to achieve performance parity with vacuum-evaporated HTLs for several polymer:fullerene combinations and is even shown to work as hole injection layer in polymer light emitting diodes (PLED). We also demonstrate that larger MoOx NCs (30–50 nm) successfully composite MoOx with Ag nanowires (NW) to form a highly conducting, transparent top anode with exceptional contact properties. This yields state-of-the-art semitransparent polymer: fullerene solar cells with PCE of 6.5% and overall transmission >30%. The remarkable performance of reflective and semitransparent OPVs is due to the uncommonly high fill factors achieved using a carefully designed strategy for implementation of MoOx nanocrystals as HTL materials. © 2016 Elsevier Ltd

  5. Brain reflections: A circuit-based framework for understanding information processing and cognitive control.

    Science.gov (United States)

    Gratton, Gabriele

    2018-03-01

    Here, I propose a view of the architecture of the human information processing system, and of how it can be adapted to changing task demands (which is the hallmark of cognitive control). This view is informed by an interpretation of brain activity as reflecting the excitability level of neural representations, encoding not only stimuli and temporal contexts, but also action plans and task goals. The proposed cognitive architecture includes three types of circuits: open circuits, involved in feed-forward processing such as that connecting stimuli with responses and characterized by brief, transient brain activity; and two types of closed circuits, positive feedback circuits (characterized by sustained, high-frequency oscillatory activity), which help select and maintain representations, and negative feedback circuits (characterized by brief, low-frequency oscillatory bursts), which are instead associated with changes in representations. Feed-forward activity is primarily responsible for the spread of activation along the information processing system. Oscillatory activity, instead, controls this spread. Sustained oscillatory activity due to both local cortical circuits (gamma) and longer corticothalamic circuits (alpha and beta) allows for the selection of individuated representations. Through the interaction of these circuits, it also allows for the preservation of representations across different temporal spans (sensory and working memory) and their spread across the brain. In contrast, brief bursts of oscillatory activity, generated by novel and/or conflicting information, lead to the interruption of sustained oscillatory activity and promote the generation of new representations. I discuss how this framework can account for a number of psychological and behavioral phenomena. © 2017 Society for Psychophysiological Research.

  6. Virtual logistics as a support for decomposition process of supply chain (conceptual reflections

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available Background: Traditionally the concept of the "supply chain" is connected with various forms of the technical, organizational and economic integration. The integration deals mainly with multilateral relations among firms, thus constituting subsequent links of products flows in supply chains and creating complex networks of business connections. Due to social and economic factors, and mainly outsourcing and resulting accent on logistics services, traditional supply chains become decomposed. Therefore, there is a need to reconsider some concepts connected with this process. Methods: The description and analysis of present and decomposing supply chains were presented and discussed. The analysis of reasons and possibilities to give up the processes of the absolute integration of supply chains in the direction of decomposed structures and the indication of possibilities to use the concept of a virtual logistics as a concept, which allows essentially such actions, was conducted. Results: The disintegration of traditional value chains is one of these kinds' concepts, which are reflected also in classic supply chains. Probably the commonly used methods of the research and analysis of these supply chains do not conduce to make decisions under conditions of the lack of the continuity of business processes. Old methods and techniques of the management do not fit fully to modern business requirements, which are probably not even fully highlighted and properly understood. Conclusions: The saturation of modern supply chains with services caused significant modifications of the logic and many mechanisms of their functioning, which in turn can lead to changes of a paradigm of the management of these more and more complex business structures. The aspirations of companies to achieve the competitive advantage on modern markets help to change the structure and the nature of supply chains, which operate on these markets, in the direction of their virtualization.

All patients completed self-report questionnaires assessing sociodemographic and clinical variables, patients’ preference of participation in decision making, perceived decisional conflict about treatment, adherence to prescribed treatment, and satisfaction with the psychiatric care provided. Multiple correspondences analysis was used to investigate relationships of decisional conflict with the variables of interest.Results: Approximately, two-thirds of psychiatric outpatients self-reported decisional conflict regarding their treatment. Interestingly, the presence of decisional conflict did not influence significantly patients’ preferences of participation or their adherence to prescribed treatment. Patients without decisional conflict registered significantly higher satisfaction. Multiple correspondences analysis evidenced two clear profiles: patients without decisional conflict received the treatment they preferred, mainly psychotherapy or combined treatment, had been under psychiatric treatment for longer than 5 years, and self-reported high satisfaction with health care received; on the other hand, patients with decisional conflict did not receive the treatment they preferred, were treated with pharmacotherapy alone for a period of time between 1 and 5 years, and self-reported medium satisfaction with received health care.Conclusion: The high level of

    The decisional balance worksheet (DBW), an open-ended measure of motivation to change, may be used to record the perceived advantages and disadvantages of substance use as well as alternative behaviors. Recent findings have indicated that the open-ended DBW can be quantified to validly reflect college students' level of motivation to reduce their drinking (Collins, Carey, & Otto, 2009). The goal of the current study was to enhance our understanding of college students' perceived advantages and disadvantages of drinking by qualitatively examining the content of their decisional balance. Participants were undergraduate college students at a 4-year university (N = 760) who participated in a randomized controlled trial of online brief motivational interventions. Using the DBW, participants recorded the advantages and disadvantages of their current drinking. Conventional content analysis methods were used to extract common themes. Social, enjoyment, and psychological reasons were the most commonly mentioned advantages of drinking, whereas physical side effects, expense and interference with goals were the most commonly mentioned disadvantages of drinking. These findings show that college students primarily use alcohol for enjoyment, particularly in social situations, as well as for coping with stress and social anxiety. On the other hand, many college students report having physical side effects from drinking as well as other kinds of concerns (e.g., expense, calories). Findings suggest that using the open-ended DBW may result in a more client-centered and accurate representation of what college students perceive as advantages and disadvantages to drinking than established, Likert-scale measures of decisional balance.

    Diagnostic decision-making is made through a combination of Systems 1 (intuition or pattern-recognition) and Systems 2 (analytic) thinking. The purpose of this study was to use the Cognitive Reflection Test (CRT) to evaluate and compare the level of Systems 1 and 2 thinking among medical students in pre-clinical and clinical programs. The CRT is a three-question test designed to measure the ability of respondents to activate metacognitive processes and switch to System 2 (analytic) thinking where System 1 (intuitive) thinking would lead them astray. Each CRT question has a correct analytical (System 2) answer and an incorrect intuitive (System 1) answer. A group of medical students in Years 2 & 3 (pre-clinical) and Years 4 (in clinical practice) of a 5-year medical degree were studied. Ten percent (13/128) of students had the intuitive answers to the three questions (suggesting they generally relied on System 1 thinking) while almost half (44%) answered all three correctly (indicating full analytical, System 2 thinking). Only 3-13% had incorrect answers (i.e. that were neither the analytical nor the intuitive responses). Non-native English speaking students (n = 11) had a lower mean number of correct answers compared to native English speakers (n = 117: 1.0 s 2.12 respectfully: p System 2 answers increased and the percentage of intuitive answers decreased in both the pre-clinical and clinical students. Up to half of the medical students demonstrated full or partial reliance on System 1 (intuitive) thinking in response to these analytical questions. While their CRT performance has no claims to make as to their future expertise as clinicians, the test may be used in helping students to understand the importance of awareness and regulation of their thinking processes in clinical practice.

    First, I would bike to thank ENRESA and the Municipality for the work in organizing this workshop. The visit to the Vandellos power station and the economic development zone, combined with the speeches, lectures, and discussions we have had here at L'Hospitalet have offered a well-rounded perspective on the inclusion of stakeholders in decision making. Even more important was that the atmosphere of the meetings was conducive to an honest and open exchange of ideas. The structure of the workshop offered ample opportunities for people to talk and listen to each other. On the whole, I believe the workshop established a learning atmosphere. In response to my charge as a rapporteur, I have endeavored to he inquisitive and to explore explanations and interpretations that may be different - although not necessarily contradictory - to those offered outright. I have been asked to participate and observe during the course of this workshop and also to comment from the perspective of a scholar who does research in the area of stakeholder involvement. I have arranged my comments as follows. First, I present some recent findings from the literature on public participation in environmental policy and decision-making. I have elected to focus on 'criteria for success'. Second, I examine the strengths of the AMA-led COWAM-2 process emerging in Spain now in the context of these criteria for success. Finally, I reflect on some of the possible shortcomings that may loom on the horizon in order to alert process planners to anticipate the unexpected. (author)

    Mediation analyses of sun protection were conducted testing structural equation models using longitudinal data with three waves. An effect was said to be mediated if the standardised path between processes of change, decisional balance and sun protection outcomes was significant. Longitudinal models of sun protection using data from individuals in the precontemplation (N = 964) and preparation (N = 463) stages who participated of an expert system intervention. Nine processes of change for sun protection, decisional balance constructs of sun protection (pros and cons), sun avoidance behaviour and sunscreen use. With the exception of two processes in the preparation stage, processes of change predicted the pros (r = .126-.614), and the pros predicted the outcomes (r = .181-.272). Three models with the cons as mediator in the preparation stage, and none in the precontemplation stage, showed a mediated relationship between processes and outcomes. In general, mediation analyses found both the process of change-to-pros and pros-to-behaviour paths significant for both precontemplation and preparation stages, and for both sun avoidance and sunscreen use outcomes. Findings provide support for the importance of assessing the role of underlying risk cognitions in improving sun protection adherence.

  14. Shared decision-making in mental health care-A user perspective on decisional needs in community-based services.

    2016-01-01

    Shared decision-making (SDM) is an emergent research topic in the field of mental health care and is considered to be a central component of a recovery-oriented system. Despite the evidence suggesting the benefits of this change in the power relationship between users and practitioners, the method has not been widely implemented in clinical practice. The objective of this study was to investigate decisional and information needs among users with mental illness as a prerequisite for the development of a decision support tool aimed at supporting SDM in community-based mental health services in Sweden. Three semi-structured focus group interviews were conducted with 22 adult users with mental illness. The transcribed interviews were analyzed using a directed content analysis. This method was used to develop an in-depth understanding of the decisional process as well as to validate and conceptually extend Elwyn et al.'s model of SDM. The model Elwyn et al. have created for SDM in somatic care fits well for mental health services, both in terms of process and content.

    Full Text Available Background: Shared decision-making (SDM is an emergent research topic in the field of mental health care and is considered to be a central component of a recovery-oriented system. Despite the evidence suggesting the benefits of this change in the power relationship between users and practitioners, the method has not been widely implemented in clinical practice. Objective: The objective of this study was to investigate decisional and information needs among users with mental illness as a prerequisite for the development of a decision support tool aimed at supporting SDM in community-based mental health services in Sweden. Methods: Three semi-structured focus group interviews were conducted with 22 adult users with mental illness. The transcribed interviews were analyzed using a directed content analysis. This method was used to develop an in-depth understanding of the decisional process as well as to validate and conceptually extend Elwyn et al.'s model of SDM. Results: The model Elwyn et al. have created for SDM in somatic care fits well for mental health services, both in terms of process and content. However, the results also suggest an extension of the model because decisions related to mental illness are often complex and involve a number of life domains. Issues related to social context and individual recovery point to the need for a preparation phase focused on establishing cooperation and mutual understanding as well as a clear follow-up phase that allows for feedback and adjustments to the decision-making process. Conclusions and Implications for Practice: The current study contributes to a deeper understanding of decisional and information needs among users of community-based mental health services that may reduce barriers to participation in decision-making. The results also shed light on attitudinal, relationship-based, and cognitive factors that are important to consider in adapting SDM in the mental health system.

To address this gap, the researchers interviewed 16 international experts in female pelvic medicine and reconstructive surgery to assess their reflective perceptions of what specific opportunities and experiences initiated and supported their development toward expertise in their field. Characteristics and influences explaining the speed and quality of expertise development were sorted into the following themes: the dynamic process of expertise development, internal and personal characteristics, general aptitudes and preparatory skills, role modeling and interpersonal influences, opportunities to learn and practice, and roles and reference points. Across the narratives and perspectives of these expert surgeons, both individual characteristics and choices, and contextual activities and opportunities were necessary and important. Experiences with greatest impact on quality of expertise development included those provided by the environment and mentors, as well as those sought out by learners themselves, to elaborate and supplement existing opportunities. The ideal combination across experts was interaction and integration of individual characteristics with experiential opportunities. Grounded in theory and research in expertise development, these findings can support improvement of medical education, both for individual mentors and strategic program development.

    Face recognition by normal subjects depends in roughly equal proportions on shape and surface reflectance cues, while object recognition depends predominantly on shape cues. It is possible that developmental prosopagnosics are deficient not in their ability to recognize faces per se, but rather in their ability to use reflectance cues. Similarly, super-recognizers' exceptional ability with face recognition may be a result of superior surface reflectance perception and memory. We tested this possibility by administering tests of face perception and face recognition in which only shape or reflectance cues are available to developmental prosopagnosics, super-recognizers, and control subjects. Face recognition ability and the relative use of shape and pigmentation were unrelated in all the tests. Subjects who were better at using shape or reflectance cues were also better at using the other type of cue. These results do not support the proposal that variation in surface reflectance perception ability is the underlying cause of variation in face recognition ability. Instead, these findings support the idea that face recognition ability is related to neural circuits using representations that integrate shape and pigmentation information.

Se realizó una encuesta estructurada a 100 ganaderos elegidos al azar entre los miembros de ASOGARI, con el fin de definir las principales tipologías y si existían diferencias entre ellos para la adopción potencial de la tecnología de bancos de proteína. Para el análisis de los factores que afectan la adopción de los bancos de proteína, se analizaron los datos de la encuesta aplicando un modelo binario basado en la premisa de que la adopción depende de los atributos y requerimientos de una tecnología dada. Además, para identificar las variables que afectaban la adopción se analizaron los datos mediante un modelo logístico de regresión múltiple conocido como Tobit. Entre los factores que más afectaron la adopción de los bancos de proteína estuvieron el acceso a la asistencia técnica, la contribución del ganado al ingreso de la finca, la disponibilidad de mano de obra, los años de experiencia en la ganadería y la escolaridad, y el acceso a incentivos para la inversión en la ganadería. El proceso de toma de decisiones para la adopción de los bancos de proteína incluyó las condiciones biofísicas (por ejemplo, la disponibilidad de tierra llana y fértil, el acceso a la semilla o materiales de siembra, las condiciones climáticas en el momento de la siembra y socioeconómicas (por ejemplo, la disponibilidad de mano de obra familiar y/o contratada, la disponibilidad de efectivo o incentivos para la siembra, los precios de la leche y los suplementos, así como una actitud favorable hacia el medio ambiente en los

Para mantener un negocio rentable y competitivo, los administradores de los centros de cultivo necesitan herramientas que sean relativamente fáciles de utilizar para facilitar la toma de decisiones de manera eficaz y oportuna. Las tallas y tiempo de cosecha, tasas de mortalidad y crecimiento, densidades de cultivo, costos y precios de mercado son variables y parámetros importantes para controlar, donde son necesarias decisiones respecto de sus niveles y valores. En este contexto modelos cuantitativos dinámicos y no-lineales deberían convertirse en herramientas valiosas para la toma de decisiones, de forma periódica, en la industria de la acuicultura. Este trabajo muestra una alternativa para emular el cultivo del ostión en Chile, mediante un modelo de simulación dinámico que imita algunas de las características de la industria. El modelo presentado se enfoca en el proceso de engorda que utiliza el enfoque tecnológico común de pearl nets y linternas en el norte de Chile, con el cual se analizaron estrategias de cultivo basadas en la talla de cosecha. Estas estrategias fueron sometidas a variaciones en los valores de los parámetros para identificar patrones de tendencia y evaluar la sensibilidad del modelo a los valores de entrada.

    Full Text Available Black coloured materials and consumer goods are known to be heating up more, because they absorb sun radiation more than light colours. This heating is a problem for the users for black automotive or motorcycle leathers and also for dark shoes and boots which are exposed to sun heat. Human vision system can distinguish visible colours between the wavelengths of 390-700 nm. So reflecting the sun radiation in the infrared area of radiation spectrum higher than 700nm, is a solution for heating problem without affecting the visible colour. For this reason IR reflective dyes and pigments are designed. A leading Leather Chemical Company has developed an IR reflecting dyeing system for leather keeping the dark coloured leathers cooler under sun radiation. Additionally in theory, fat and water content of leather affects its heating properties. In this study, effect of natural, synthetic and waterproof fatliquoring systems on heating properties of leathers coloured with IR reflective dyes and pigments are investigated.

    Steel tape scale grating of a reflective incremental linear encoder has a key impact on the measurement accuracy of the optical encoder. However, it is difficult for conventional manufacturing processes to fabricate scale grating with high-resolution grating strips, due to process and material problems. In this paper, self-assembly technology was employed to fabricate high-resolution steel tape scale grating for a reflective incremental linear encoder. Graphene oxide nanoparticles were adopted to form anti-reflective grating strips of steel tape scale grating. They were deposited in the tape, which had a hydrophobic and hydrophilic grating pattern when the dispersion of the nanoparticles evaporated. A standard lift-off process was employed to fabricate the hydrophobic grating strips on the steel tape. Simultaneously, the steel tape itself presents a hydrophilic property. The hydrophobic and hydrophilic grating pattern was thus obtained. In this study, octafluorocyclobutane was used to prepare the hydrophobic grating strips, due to its hydrophobic property. High-resolution graphene oxide steel tape scale grating with a pitch of 20 μ m was obtained through the self-assembly process. The photoelectric signals of the optical encoder containing the graphene oxide scale grating and conventional scale grating were tested under the same conditions. Comparison test results showed that the graphene oxide scale grating has a better performance in its amplitude and harmonic components than that of the conventional steel tape scale. A comparison experiment of position errors was also conducted, demonstrating an improvement in the positioning error of the graphene oxide scale grating. The comparison results demonstrated the applicability of the proposed self-assembly process to fabricate high-resolution graphene oxide scale grating for a reflective incremental linear encoder.

    Decisional regret is defined as distress after making a health care choice and can be an issue for parents electing distal hypospadias repair for their sons. We assessed the influence on decisional regret of variables related to the family, surgery and outcomes. Charts for 372 patients undergoing primary distal hypospadias repair between 2005 and 2012 were reviewed, and validated questionnaires, including the Decisional Regret Scale, Pediatric Penile Perception Score and Dysfunctional Voiding and Incontinence Scoring System, were administered to parents. Data were available for 172 of 372 families (response rate 46.2%). Of 323 parents 128 (39.6%) presented with moderately strong decisional regret, with good agreement within couples. Predictors of decisional regret included intermediate parental educational level (OR 3.19, 95% CI 1.52-6.69), patient not being the first born (OR 2.01, 95% CI 1.07-3.78), family history of hypospadias (OR 4.42, 95% CI 1.96-9.97), initial desire to avoid surgery (OR 2.07, 95% CI 1.04-4.12), younger age at followup (OR 0.81, 95% CI 0.72-0.91), presence of lower urinary tract symptoms (OR 4.92, 95% CI 1.53-15.81) and lower Pediatric Penile Perception Score (OR 0.86, 95% CI 0.75-0.99). Decisional regret was unrelated to parental desire to avoid circumcision, surgical variables, development of complications and duration of followup. Decisional regret is a problem in a significant proportion of parents electing distal hypospadias repair for their sons. In our experience family variables seemed to be predictors of decisional regret, while surgical variables did not. Predictors of decisional regret included worse parental perception of penile appearance and the presence of lower urinary tract symptoms. However, the latter could be unrelated to surgery. Irrespective of the duration of followup, decisional regret seems decreased in parents of older patients. Copyright © 2016 American Urological Association Education and Research, Inc

    Extracellular matrix (ECM) proteins, such as collagen type I and elastin, and intermediate filament (IMF) proteins, such as vimentin are modified and dysregulated as part of the malignant changes leading to disruption of tissue homeostasis. Noninvasive biomarkers that reflect such changes may have a great potential for cancer. Levels of matrix metalloproteinase (MMP) generated fragments of type I collagen (C1M), of elastin (ELM), and of citrullinated vimentin (VICM) were measured in serum from patients with lung cancer (n = 40), gastrointestinal cancer (n = 25), prostate cancer (n = 14), malignant melanoma (n = 7), chronic obstructive pulmonary disease (COPD) (n = 13), and idiopathic pulmonary fibrosis (IPF) (n = 10), as well as in age-matched controls (n = 33). The area under the receiver operating characteristics (AUROC) was calculated and a diagnostic decision tree generated from specific cutoff values. C1M and VICM were significantly elevated in lung cancer patients as compared with healthy controls (AUROC = 0.98, P < 0.0001) and other cancers (AUROC = 0.83 P < 0.0001). A trend was detected when comparing lung cancer with COPD+IPF. No difference could be seen for ELM. Interestingly, C1M and VICM were able to identify patients with lung cancer with a positive predictive value of 0.9 and an odds ratio of 40 (95% CI = 8.7–186, P < 0.0001). Biomarkers specifically reflecting degradation of collagen type I and citrullinated vimentin are applicable for lung cancer patients. Our data indicate that biomarkers reflecting ECM and IMF protein dysregulation are highly applicable in the lung cancer setting. We speculate that these markers may aid in diagnosing and characterizing patients with lung cancer

    The practice of community based participatory research (CBPR) has evolved over the past 20 years with the recognition that health equity is best achieved when academic researchers form collaborative partnerships with communities. This article theorizes the possibility that core principles of CBPR cannot be realistically applied unless unequal power relations are identified and addressed. It provides theoretical and empirical perspectives for understanding power, privilege, researcher identity and academic research team composition, and their effects on partnering processes and health disparity outcomes. The team's processes of conducting seven case studies of diverse partnerships in a national cross-site CBPR study are analyzed; the multi-disciplinary research team's self-reflections on identity and positionality are analyzed, privileging its combined racial, ethnic, and gendered life experiences, and integrating feminist and post-colonial theory into these reflections. Findings from the inquiry are shared, and incorporating academic researcher team identity is recommended as a core component of equalizing power distribution within CBPR.

    Full Text Available Según la hipótesis del marcador somático, la toma de decisiones resulta adaptativa cuando los procesos emocionales se integran a la actividad cognitiva. La primacía del sistema afectivo sobre el control cognitivo en los jóvenes se relaciona con una toma de decisiones en función de la gratificación inmediata, sin tener en cuenta posibles consecuencias perjudiciales futuras. El consumo intensivo de alcohol, muy frecuente en los jóvenes, se asocia a una acrecentada toma de decisiones desadaptativa. El objetivo del presente estudio fue evaluar la toma de decisiones en jóvenes de ambos sexos consumidores moderados e intensivos de alcohol, según el tipo de inducción emocional a la que fueron expuestos. Mediante un diseño factorial con pre- y postest, se estudió la toma de decisiones en 79 participantes de 18 a 29 años, antes y después de la inducción emocional positiva o negativa. Para evaluar la toma de decisiones, se administraron las pruebas Iowa Gambling Task y Cognitive Bias Task. Para inducir emociones se utilizaron fragmentos de películas. Además, se registró la frecuencia cardíaca durante la experimentación. Como resultado, se encontró que las mujeres inducidas negativamente y los hombres inducidos positivamente obtuvieron peor rendimiento en la Iowa Gambling Task. La frecuencia cardíaca disminuyó durante las sesiones experimentales respecto del periodo basal. Los consumidores intensivos tuvieron peor rendimiento en la Cognitive Bias Task respecto de los consumidores moderados. Se concluye que la experiencia emocional y el tipo de consumo de alcohol influyen sobre la toma de decisiones en los jóvenes universitarios.

    The benefits of bone-anchored hearing devices (BAHD) in children with unilateral aural atresia are controversial. We sought to determine whether there is parental decisional conflict surrounding elective placement of BAHD for this indication. Caregivers of pediatric patients with unilateral aural atresia and normal contralateral ear undergoing percutaneous BAHD consultation were enrolled. All consultations were carried out by one pediatric otolaryngologist in a consistent manner. After consultation, the participants completed a demographics form and the Decisional Conflict Scale (DCS) questionnaire. Twenty-three caregivers of 15 male (65.2%) and 8 female (34.8%) children (mean age 5.65 years) participated. The overall median DCS score was 15.63 (standard error = 4.21). Significant decisional conflict (DCS score ≥ 25) was found in 10 participants (43.5%). The median DCS score in the group choosing surgery was 5.47, and it was 23.44 in those who did not choose surgery (Mann-Whitney U = 39, Z = -1.391, P = .164). The median DCS score for mothers and fathers was 25 and 3.91, respectively.

    To examine the impact of a decision aid (DA) designed to promote informed decision making for screening with the prostate-specific antigen (PSA) test and to test a theoretical model of factors influencing decisional conflict. Structural equation modeling examined pathways between DA exposure, knowledge, schema, prostate cancer risk perceptions, decisional anxiety, and decisional conflict. Sample participants included 200 men from the general population (exclusive of African Americans) and 200 African American men. Half of the men in each subsample were randomly assigned to receive the DA. Decisional conflict regarding prostate cancer screening. The DA influences level of decisional conflict by increasing patient knowledge. This effect of knowledge on decisional conflict is indirect, however, through an association with greater perceived risk and lower decisional anxiety. Also, positive PSA schema was associated with lower decisional anxiety and decisional conflict. It is important that exposure to the DA had no impact on PSA schema. Schemas about testing must be considered in developing messages about the risks and benefits of testing. If schemas are counter to message content, mechanisms for modifying schemas must be incorporated into interventions.

    Full Text Available Background: The KwaZulu-Natal Sandstone Sourveld (KZNSS Research Programme is part of a collaborative, transdisciplinary research partnership between the University of KwaZulu-Natal and the eThekwini Municipality (EM, aimed at bridging the science-policy-practice gap. The research programme focuses on generating knowledge and capacity to support local land-use planning, management and policy development related to biodiversity and climate change issues. Objectives: The objectives were (1 to describe how a continuous reflective evaluation approach helped to better understand the research programme and its outcomes; and (2 to assess research outputs and outcomes, relevance of outcomes to the requirements of EM, and participants’ perceptions of the programme (both the outcomes and the process. Methods: The evaluation took a mixed methods approach, combining various quantitative and qualitative methods such as anonymous individual questionnaires, reflective exercises and group reflections. Results: The KZNSS programme was successful in capacity building and establishing a long-term partnership, but had lower scientific publication output and practice uptake than expected. Participants’ perceptions changed over time, with a decrease in the perceived success of addressing tangible research outcomes, and an increase in the perceived success of collaborative relationships in the partnership. Conclusion: Transdisciplinary partnerships can be a means of integrating research into policy and practice through knowledge exchange. An important lesson in the early stages of this partnership was to pay attention to the process and not only the outputs. The study highlights the importance of continuous participatory reflection and evaluation in such partnerships.

    2015-01-01

    In 1983, a group of 14 prominent psychotherapy process researchers attended a workshop sponsored by the US National Institute of Mental Health. Although the previous decade had seen a marked emphasis on psychotherapy outcome research, there had also been several major advances in the field of process research. The goals of the workshop were to review the current state of the field, address methodological and conceptual issues, and provide recommendations to advance scholarship in this area. In this paper, we summarize the major themes of the workshop and consider the degree to which its recommendations have come to fruition via subsequent developments in the field. Although 30 years have passed since the workshop was held, its insights remain highly relevant to psychotherapy process research today.

    Slowed information processing speed is commonly reported in persons with multiple sclerosis (MS), and is typically investigated using clinical neuropsychological tests, which provide sensitive indices of mean-level information processing speed. However, recent studies have demonstrated that within-person variability or intra-individual variability (IIV) in information processing speed may be a more sensitive indicator of neurologic status than mean-level performance on clinical tests. We evaluated the neural basis of increased IIV in mildly affected relapsing-remitting MS patients by characterizing the relation between IIV (controlling for mean-level performance) and white matter integrity using diffusion tensor imaging (DTI). Twenty women with relapsing-remitting MS and 20 matched control participants completed the Computerized Test of Information Processing (CTIP), from which both mean response time and IIV were calculated. Other clinical measures of information processing speed were also collected. Relations between IIV on the CTIP and DTI metrics of white matter microstructure were evaluated using tract-based spatial statistics. We observed slower and more variable responses on the CTIP in MS patients relative to controls. Significant relations between white matter microstructure and IIV were observed for MS patients. Increased IIV was associated with reduced integrity in more white matter tracts than was slowed information processing speed as measured by either mean CTIP response time or other neuropsychological test scores. Thus, despite the common use of mean-level performance as an index of cognitive dysfunction in MS, IIV may be more sensitive to the overall burden of white matter disease at the microstructural level. Furthermore, our study highlights the potential value of considering within-person fluctuations, in addition to mean-level performance, for uncovering brain-behavior relationships in neurologic disorders with widespread white matter pathology.

    Full Text Available Recognizing the importance of nutrition as part of the grand challenges faced by humanity—the current epidemic of non-communicable diseases (NCDs, sustainability and maintenance of Planetary Health—the United Nations (UN has declared 2016–2025 the Decade of Nutrition. Research continues to underscore the extent to which ultra-processed foods dominate the contemporary nutritional landscape. Moreover, the dual role played by food technology and marketing in the expansion of ultra-processed foods is under increased scrutiny. As public health experts and clinicians contend with a crisis of NCDs, attempting to untangle a knotted assortment of interrelated strands of causation, an examination of the early origins of highly-marketed ultra-processed foods can provide valuable lessons. Here, we illuminate a little-known piece of history in the annals of ultra-processed nutritional science and childhood welfare. Astrofood was a commercially-marketed, collaborative government-industry effort that brought soy protein-enriched Twinkies as a nutritive breakfast cake to disadvantaged children; its concept and delivery demonstrated an unwillingness to deal with root-cause challenges. Although its official tenure was only about 7 years, we argue that Astrofood and its total food engineering still resonate throughout the global ultra-processed nutritional landscape. New scientific advances in nutritional psychiatry and the microbiome are on a collision course with the profits, marketing and intellectual dishonesty of the ultra-processed food industry. Solutions to the grand challenges of the Decade of Nutrition may be found in lessons from Astrofood. They provide clues to undoing the tangled knots which otherwise maintain an untenable status quo.

    Full Text Available This study was conducted to investigate the data about the Bologna Process on the websites of universities’ undergraduate nursing programs in Turkey. In this descriptive study, all state and private universities which have BSc Nursing Programs and are within the scope of the Council of Higher Education of Turkey were included. Data were collected between May 1st and June 1st, 2015 by searching the websites of universities that were included in this study. An Evaluation Form that was developed by the researchers was used to collect data. Data were analyzed by using frequencies and percentages. We found that 77.2% of the universities included in the study were state universities and information about the Bologna Process could be found by using the website link on the main page in 65.3% of these universities. The majority of the universities (87.1% had general information about their program but 44% did not take the European Credit Transfer System into consideration on compulsory lessons and 41% of them on elective lessons. It was found that the majority of essential nursing lessons held by eight departments in BSc of Nursing programs had an Information Package of Lessons (68.1%-77.6% and that this package contained information on the European Credit Transfer System Credits in 72.3%-82.7% and calculations of student workload in 54.2%-65.6%. In conclusion, the universities with BSc Nursing Program did not have full information about the Bologna Process on their websites. We recommend making the necessary updates on these websites according to the standard format of the Council of Higher Education of Turkey to avoid giving inadequate and false information about the Bologna Process.

  5. Low-Frequency Cortical Entrainment to Speech Reflects Phoneme-Level Processing.

    Science.gov (United States)

    Di Liberto, Giovanni M; O'Sullivan, James A; Lalor, Edmund C

    2015-10-05

    The human ability to understand speech is underpinned by a hierarchical auditory system whose successive stages process increasingly complex attributes of the acoustic input. It has been suggested that to produce categorical speech perception, this system must elicit consistent neural responses to speech tokens (e.g., phonemes) despite variations in their acoustics. Here, using electroencephalography (EEG), we provide evidence for this categorical phoneme-level speech processing by showing that the relationship between continuous speech and neural activity is best described when that speech is represented using both low-level spectrotemporal information and categorical labeling of phonetic features. Furthermore, the mapping between phonemes and EEG becomes more discriminative for phonetic features at longer latencies, in line with what one might expect from a hierarchical system. Importantly, these effects are not seen for time-reversed speech. These findings may form the basis for future research on natural language processing in specific cohorts of interest and for broader insights into how brains transform acoustic input into meaning.

    2013-02-01

    Fluidized bed granulation is a commonly used unit operation in the pharmaceutical industry. But still to obtain and control the desired granule size is challenging due to many process variables affecting the final product. Focused beam reflectance measurement (FBRM, Mettler-Toledo, Switzerland) is an increasingly popular particle growth analysis technique. FBRM tool was installed in two different locations inside a fluidized bed granulator (GPCG2, Glatt, Binzen) in order to monitor the granulation growth kinetics. An experimental design was created to study the effect of process variables using FBRM probe and comparing the results with the one's measured by sieve analysis. The probe location is of major importance to get smooth and robust curves. The excess feeding of binder solution might lead to agglomeration and thus to process collapse, however this phenomenon was clearly detected with FBRM method. On the other hand, the process variables at certain levels might affect the FBRM efficiency by blocking the probe window with sticky particles. A good correlation was obtained (R(2) = 0.95) between FBRM and sieve analysis mean particle size. The proposed in-line monitoring tool enables the operator to select appropriate process parameters and control the wet granulation process more efficiently.

The social work class seeks new foundations that allow within the context of structural change, the strengthening of professional identity and challenge of the vestiges of intellectual segregation that historical constraints have left. This paper seeks to outline a research strategy for reconciliation and coordination of intellectual and professional work in order to give visibility to new and different domains of interpretation and action, while claiming that considering pluri-perspectives potentiates the knowledge transformation process. Underlining this confluence of complex thinking elements, this article incorporates the space-time dimension and discusses and recognizes the unavoidable circularity as a way to interrogate knowledge that is compartmentalized and fragmented, placing an emphasis both on knowledge and on the interrelationship between knowing, doing, being and relating. In addition, examines the recognition of the nature of those relationships among various disciplines and perspectives.

    Full text: Infrared reflection absorption spectroscopy (IRRAS) was applied to study the regularities of radiation conversion of hexane on the surface of aluminum. The research object was the thin polished aluminum plate by mark of AD-00 with reflection coefficient R=0.8†0.85 in infrared range λ=2.2†15 μ . As adsorbate unsaturated vapors of spectroscopy clear hexane were used. The absorption of hexane (C 2 H 14 ) was being studied manometric at pressures P=(0.1†1.0)·10 2 Pa , what corresponded to monolayer value of 1-10. The samples were irradiated with γ-quanta of 60 Co with D=1.03 Gy·s -1 doze rate. Infrared reflection spectrum when linear-polarized radiation fall on the sample under angle ψ=10 o was measured by spectrophotometer 'Specord 71 JR' in diapason of 4000-650cm -1 at the temperature by mean of special reflecting arrangements. Formation of molecular hydrogen (H 2 ) and other gaseous products of decomposition were controlled by chromotographical and infrared spectroscopical methods. The analysis of hexane infrared absorption spectra after radiation-stimulated adsorption on the surface of aluminum, points out the formation of H-bonded hydrocarbon complex ( ν∼2680cm -1 ) with much loosening of C-H bond (the molecular form of absorption) and the possibility of proceeding dissociative absorption with formation of metal-alkyls (ν∼2880, 2920, 2970 cm -1 ). Probability of the last mentioned process, which proceeds in the most defective centers, increases with increasing of γ-radiation doze. It was established that the radiation processes in hetero system Al-ads.C 6 H 14 accelerate the radiolysis of hexane. At all these the radiation decomposition of hexane in hetero system Al-ads.C 6 H 14 is accompanied by formation the surface hydrides (ν∼1700-2000 cm -1 ), acetylene (ν∼3200-3300 cm -1 ), ethylene (ν∼980 cm -1 ), and also gaseous products of molecular hydrogen decomposition (H 2 ) and hydrocarbons C 1 -C 5 (bands with maxima 770, 790

  17. The Formation of Chimeric Nanomorphologies, as a Reflection of Naturally Occurring Thermodynamic Processes

    Science.gov (United States)

    Naziris, N.; Demetzos, C.

    2017-11-01

    The self-assembly process of different in nature biomaterials leads to the morphogenesis of various nano-structures, where the individual molecule properties (e.g. hydrophilic-to-hydrophobic balance and elasticity), profoundly affect the intermediate surfaces’ interfacial thermodynamics. Herein, the mixing of a phospholipid and an amphiphilic block copolymer, through the thin-film hydration method, gave different morphologies, among which there were vesicles (i.e. liposomes and polymersomes), micelles and worm-like structures. The formation of such variety of structures is attributed to divergent entropic pathways, which are determined by a number of parameters, such as the lipid:polymer molar ratio and the polymer composition. The developed nanosystems are considered as chimeric/mixed, because of the two different in type biomaterials that compose them. The vesicles also exhibited membrane “irregularities”, which are connected with their biophysical behavior. Nature has “chosen” vesicular forms to be the thermodynamically stable “biological apartments”, in which life was enclosed and additionally, vesicles provided compartmentalized systems, where the intracellular environment was built. Phospholipid properties result in membranes/bilayers that harmonically assimilate other molecules, like proteins and retain their integrity and functionality, while gaining additional features. A cause that alters this relationship might induce changes in the membrane composition and morphology, with respect to lipid rafts/domains, what has been linked with the activation and development of certain human disorders/diseases.

    Results: Ten percent (13/128 of students had the intuitive answers to the three questions (suggesting they generally relied on System 1 thinking while almost half (44% answered all three correctly (indicating full analytical, System 2 thinking. Only 3-13% had incorrect answers (i.e. that were neither the analytical nor the intuitive responses. Non-native English speaking students (n = 11 had a lower mean number of correct answers compared to native English speakers (n = 117: 1.0 s 2.12 respectfully: p < 0.01. As students progressed through questions 1 to 3, the percentage of correct System 2 answers increased and the percentage of intuitive answers decreased in both the pre-clinical and clinical students. Conclusions: Up to half of the medical students demonstrated full or partial reliance on System 1 (intuitive thinking in response to these analytical questions. While their CRT performance has no claims to make as to their future expertise as clinicians, the test may be used in helping students to understand the importance of awareness and regulation of their thinking processes in clinical practice.

    Biochemical and structural leaf properties such as chlorophyll content (Chl), nitrogen content (N), leaf water content (LWC), and specific leaf area (SLA) have the benefit to be estimated through nondestructive spectral measurements. Current practices, however, mainly focus on a limited amount of wavelength bands while more information could be extracted from other wavelengths in the full range (400-2500nm) spectrum. In this research, leaf characteristics were estimated from a field-based multi-species dataset, covering a wide range in leaf structures and Chl concentrations. The dataset contains leaves with extremely high Chl concentrations (>100μgcm(-2)), which are seldom estimated. Parameter retrieval was conducted with the machine learning regression algorithm Gaussian Processes (GP), which is able to perform adaptive, nonlinear data fitting for complex datasets. Moreover, insight in relevant bands is provided during the development of a regression model. Consequently, the physical meaning of the model can be explored. Best estimates of SLA, LWC and Chl yielded a best obtained normalized root mean square error of 6.0%, 7.7%, 9.1%, respectively. Several distinct wavebands were chosen across the whole spectrum. A band in the red edge (710nm) appeared to be most important for the estimation of Chl. Interestingly, spectral features related to biochemicals with a structural or carbon storage function (e.g. 1090, 1550, 1670, 1730nm) were found important not only for estimation of SLA, but also for LWC, Chl or N estimation. Similar, Chl estimation was also helped by some wavebands related to water content (950, 1430nm) due to correlation between the parameters. It is shown that leaf parameter retrieval by GP regression is successful, and able to cope with large structural differences between leaves. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available This study compared automatic and controlled cognitive processes that underlie event-related potentials (ERPs effects during speech perception. Sentences were presented to French native speakers, and the final word could be congruent or incongruent, and presented at one of four levels of degradation (using a modulation with pink noise: no degradation, mild degradation (2 levels, or strong degradation. We assumed that degradation impairs controlled more than automatic processes. The N400 and Late Positive Complex (LPC effects were defined as the differences between the corresponding wave amplitudes to incongruent words minus congruent words. Under mild degradation, where controlled sentence-level processing could still occur (as indicated by behavioral data, both N400 and LPC effects were delayed and the latter effect was reduced. Under strong degradation, where sentence processing was rather automatic (as indicated by behavioral data, no ERP effect remained. These results suggest that ERP effects elicited in complex contexts, such as sentences, reflect controlled rather than automatic mechanisms of speech processing. These results differ from the results of experiments that used word-pair or word-list paradigms.

    Human information processing is sensitive to aversive stimuli, in particular to negative cues that indicate a threat to physical integrity. We investigated the extent to which these findings can be transferred to stimuli that are associated with a social rather than a physical threat. Event-related potentials were recorded during silent reading of neutral, positive, physically threatening, and socially threatening words, whereby socially threatening words were represented by swear words. We found facilitated processing of positive and physically threatening words in contrast to both neutral and socially threatening words at a first potential that emerged at about 120 ms after stimulus onset. At a semantic processing stage reflected by the N400, processing of all classes of affective words, including socially threatening words, differed from neutral words. We conclude that socially threatening words as well as neutral words capture more attentional resources than positive and physically threatening words at early stages. However, social threatening words are processed in a manner similar to other emotional words and different from neutral words at higher levels.

    The rising health care costs and increasing older adult population in the United States make preventive medicine for this age group especially crucial. Regular physical activity and fruit and vegetable consumption may prevent or delay the onset of many chronic conditions that are common among older adults. The decisional balance sheet is a promotional tool targeting the perceived pros and cons of behavior adoption. The current study tested the efficiency and effectiveness of a single-day decisional balance sheet program, targeting increased physical activity and fruit and vegetable intake among older adults. Participating adults (N = 21, age = 72.2) who represented a diverse population in Hawaii (Japanese = 5, Filipino = 4, Caucasian = 4, Native American = 1, Native Hawaiian = 1, Hispanic = 1, and Others = 5) were recruited from housing communities and randomized to a decisional balance sheet program adapted for physical activity or fruit and vegetable consumption. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ) short form, and daily fruit and vegetable intake with the National Health and Nutrition Examination Survey single item instrument. Baseline and follow-up data were collected. Both programs were implemented efficiently, and participants in both groups improved their daily physical activity. The decisional balance sheet for fruit and vegetable consumption appeared less effective. Specific suggestions for similar programs are reported. © 2011 Wiley Periodicals, Inc.

  11. 024 PP: MEANINGFUL AND ENGAGING, OR TOKENISTIC? REFLECTIONS ON COLLABORATIVE ENGAGEMENT IN THE PROCESS OF DESIGNING SEXUAL HEALTH INTERVENTIONS

    Boydell, N; McDaid, L

    2017-01-01

    Working with non-academic partners and including participants, and other stakeholders, in the design and delivery of research is emerging as a critical element in the field of health research. As researchers based in an interdisciplinary team with a focus on the development of sexual health interventions, we have long recognised that engagement with individuals and communities is a critical part of the research process, and actively sought out opportunities to collaborate with non-academic partners with a view to ensuring that our work is relevant in the ‘real-world’. While the increasing call for ‘collaboration’, ‘patient and public involvement’ and ‘co-production’ is welcome, we recognise the possibility that without critical reflection on the part of the research team, such engagement can lack meaning for those being asked to participate, potentially reducing its value and risking it being perceived as tokenistic. In this paper we reflect on our experiences as qualitative researchers for whom a key role in interdisciplinary research teams has been undertaking a number of ‘patient public involvement’ projects with both young people and gay, bisexual and other men who have sex with men (MSM) to inform the development of sexual health interventions. We critically reflect on some of the challenges and opportunities involved in this form of ‘consultation’, and explore the ethical implications of engaging stakeholders in identifying issues they consider important as part of the design and delivery of future interventions, but which may not be considered either a priority or feasible.

    Background Understanding family caregivers’ decisional role preferences is important for communication, quality of care, and patient and family satisfaction. The family caregiver has an important role in a patient’s decisional role preferences. There are limited studies on family caregivers’ preferences of the patient’s decisional control at the end of life among Hispanics. Aims To identify Hispanic caregivers’ preferences of the decision control of patients with advanced cancer and to compare the preferences of caregivers in Latin America (HLA) and Hispanic American (HUSA) caregivers. Design We surveyed patients and their family caregivers referred to outpatient palliative care clinics in the United States, Chile, Argentina, and Guatemala. Caregiver preferences of patient’s decisional control were evaluated using the Control Preference Scale. Caregivers’ and patients’ socio-demographic variables, patient performance status, and HUSA patient acculturation level was also collected. Participants A total of 387 caregivers were surveyed: 100 (26%) in Chile, 99 (26%) in Argentina, 97 (25%) in Guatemala, and 91 (24%) in the United States. The median age was 56 years, and 59% were female. Results Caregiver preference of patients decisions control was passive, shared, and active by 10 (11%), 45 (52%) and 32 (37%) HUSA caregivers and 54 (19%), 178 (62%) and 55 (19%) HLA caregivers (p=0.0023). Caregiver acculturation level did not affect the preferences of the HUSA sample (p=0.60). Conclusions Most Hispanic family caregivers preferred the patient to make shared decisions. HLA caregivers preferred more frequently patients to assume a passive decisional role. Acculturation did not influence the preferences of HUSA caregivers. PMID:23670718

  13. Access is mainly a second-order process: SDT models whether phenomenally (first-order) conscious states are accessed by reflectively (second-order) conscious processes.

    Access can either be first-order or second-order. First order access concerns whether contents achieve representation in phenomenal consciousness at all; second-order access concerns whether phenomenally conscious contents are selected for metacognitive, higher order processing by reflective consciousness. When the optional and flexible nature of second-order access is kept in mind, there remain strong reasons to believe that exclusion failure can indeed isolate phenomenally conscious stimuli that are not so accessed. Irvine's [Irvine, E. (2009). Signal detection theory, the exclusion failure paradigm and weak consciousness-Evidence for the access/phenomenal distinction? Consciousness and Cognition.] partial access argument fails because exclusion failure is indeed due to lack of second-order access, not insufficient phenomenally conscious information. Further, the enable account conforms with both qualitative differences and subjective report, and is simpler than the endow account. Finally, although first-order access may be a distinct and important process, second-order access arguably reflects the core meaning of access generally.

  14. Impulsivity, impulsive and reflective processes and the development of alcohol use and misuse in adolescents and young adults

    Full Text Available This paper contrasts dual-process and personality approaches in the prediction of addictive behaviors and related risk behaviors. In dual-process models, behavior is described as the joint outcome of qualitatively different “impulsive” (or associative and “reflective” processes. There are important individual differences regarding both types of processes, and the relative strength of both in a specific situation is influenced by prior behavior and state variables (e.g., fatigue, alcohol use. From this perspective, a specific behavior (e.g., alcohol misuse can be predicted by the combined indices of the behavior-related impulsive processes (e.g., associations with alcohol, and reflective processes, including the ability to refrain from a motivationally salient action. Personality approaches have reported that general traits such as impulsivity predict addictive behaviors. Here we contrast these two approaches, with supplementary analyses on four datasets. We hypothesized that trait impulsivity can predict specific risky behaviors, but that its predictive power disappears once specific behavior-related associations, indicators of executive functioning, and their interaction are entered into the equation. In all four studies the observed interaction between specific associations and Executive Control (EC was robust: trait impulsivity did not diminish the prediction of alcohol use by the interaction. Trait impulsivity was not always related to alcohol use, and when it was, the predictive power disappeared after entering the interaction between behavior-specific associations and EC in one study, but not in the other. These findings are interpreted in relation to the validity of the measurements used, which leads to a more refined hypothesis.

  15. What can other animals tell us about human social cognition?An evolutionary perspective on reflective and reflexive processing

    Directory of Open Access Journals (Sweden)

    Erin E Hecht

    2012-07-01

    Full Text Available Human neuroscience has seen a recent boom in studies on reflective, controlled, explicit social cognitive functions like imitation, perspective‐taking, and empathy. The relationship of these higher‐level functions to lower‐level, reflexive, automatic, implicit functions is an area of current research. As the field continues to address this relationship, we suggest that an evolutionary, comparative approach will be useful, even essential. There is a large body of research on reflexive, automatic, implicit processes in animals. A growing perspective sees social cognitive processes as phylogenically continuous, making findings in other species relevant for understanding our own. One of these phylogenically continuous processes appears to be self‐other matching or simulation. Mice are more sensitive to pain after watching other mice experience pain; geese experience heart rate increases when seeing their mate in conflict; and infant macaques, chimpanzees, and humans automatically mimic adult facial expressions. In this article, we review findings in different species that illustrate how such reflexive processes are related to (higher order reflexive processes, such as cognitive empathy, theory of mind, and learning by imitation. We do so in the context of self‐other matching in three different domains – in the motor domain (somatomotor movements, in the perceptual domain (eye movements and cognition about visual perception, and in the autonomic/emotional domain. We also review research on the developmental origin of these processes and their neural bases across species. We highlight gaps in existing knowledge and point out some questions for future research. We conclude that our understanding of the psychological and neural mechanisms of self‐other mapping and other functions in our own species can be informed by considering the layered complexity these functions in other species.

    Innovative educational strategies can provide variety and enhance student learning while addressing complex logistical and financial issues facing modern anatomy education. Observe-Reflect-Draw-Edit-Repeat (ORDER), a novel cyclical artistic process, has been designed based on cognitivist and constructivist learning theories, and on processes of critical observation, reflection and drawing in anatomy learning. ORDER was initially investigated in the context of a compulsory first year surface anatomy practical (ORDER-SAP) at a United Kingdom medical school in which a cross-over trial with pre-post anatomy knowledge testing was utilized and student perceptions were identified. Despite positive perceptions of ORDER-SAP, medical student (n = 154) pre-post knowledge test scores were significantly greater (P learning methods (3.26, SD = ±2.25) than with ORDER-SAP (2.17, ±2.30). Based on these findings, ORDER was modified and evaluated in the context of an optional self-directed gross anatomy online interactive tutorial (ORDER-IT) for participating first year medical students (n = 55). Student performance was significantly greater (P  0.05) to those students without these characteristics. These findings will be of value to anatomy instructors seeking to engage students from diverse learning backgrounds in a research-led, innovative, time and cost-effective learning method, in the context of contrasting learning environments.

    The value of collaborative concept mapping in assisting students to develop an understanding of complex concepts across a broad range of basic and applied science subjects is well documented. Less is known about students' learning processes that occur during the construction of a concept map, especially in the context of clinical cases in veterinary medicine. This study investigated the unfolding collaborative learning processes that took place in real-time concept mapping of a clinical case by veterinary medical students and explored students' and their teacher's reflections on the value of this activity. This study had two parts. The first part investigated the cognitive and metacognitive learning processes of two groups of students who displayed divergent learning outcomes in a concept mapping task. Meaningful group differences were found in their level of learning engagement in terms of the extent to which they spent time understanding and co-constructing knowledge along with completing the task at hand. The second part explored students' and their teacher's views on the value of concept mapping as a learning and teaching tool. The students' and their teacher's perceptions revealed congruent and contrasting notions about the usefulness of concept mapping. The relevance of concept mapping to clinical case-based learning in veterinary medicine is discussed, along with directions for future research.

    As part of a cooperative effort among the U.S. Geological Survey (USGS), the U.S. Department of Energy, and the U.S. Department of the Interior Bureau of Ocean Energy Management, two grids of two-dimensional multichannel seismic reflection data were acquired in the Gulf of Mexico over lease blocks Green Canyon 955 and Walker Ridge 313 between April 18 and May 3, 2013. The purpose of the data acquisition was to fill knowledge gaps in an ongoing study of known gas hydrate accumulations in the area. These data were initially processed onboard the recording ship R/V Pelican for more quality control during the recording. The data were subsequently processed in detail by the U.S. Geological Survey in Denver, Colorado, in two phases. The first phase was to create a “kinematic” dataset that removed extensive noise present in the data but did not preserve relative amplitudes. The second phase was to create a true relative amplitude dataset that included noise removal and “wavelet” deconvolution that preserved the amplitude information. This report describes the processing techniques used to create both datasets.

    Full Text Available Studying the problems related to the process of the Azerbaijanian people formation requires a comprehensive analysis of mutual relations of the Turkic tribes – the Huns, the Sabirs and the Khazars – with the local population of Azerbaijan in the early Middle Ages. The article is devoted to the process of penetration of the Huns, the Sabirs and the Khazars to Azerbaijan, their role in the formation of the Azerbaijanian people and the reflection of this process in the country’s toponymy. In the early Middle Ages the process of penetration of Turkic tribes in Azerbaijan from the north, through the Derbent passage, intensified. Primary sources indicate that over the centuries the Huns (3rd – 4th centuries, the Sabirs (5th – 6th centuries and the Khazars (7th – 8th centuries made continuous attacks on Azerbaijan and neighboring countries from the north. Upon the arrival of the Turkic tribes in Azerbaijan from the north in the 3rd – 4th centuries, the Turkic language in the country was extensively spread. Just since then the ethnotoponyms “Hun”, “Suvar” and “Khazar” became consolidated in the toponymy of Azerbaijan. Revealing the meaning of toponyms, ethnonyms, town names, hydronyms, introduced in language use in the 3rd – 8th centuries and associated with the aforementioned tribes, has exceptional value for recreating the ethnic view of Azerbaijan of the studied epoch. They let us come to the conclusion that the Huns, the Sabirs and the Khazars were important ethnic elements in the process of ethnogenesis of the Azerbaijanian people.

    Introduction: It is generally accepted that metabolic inflammation in the liver is an important driver of disease progression in NASH and associated matrix remodeling/fibrosis. However, the exact molecular inflammatory mechanisms are poorly defined in human studies. Investigation of key pathogenic mechanisms requires the use of pre-clinical models, for instance for time-resolved studies. Such models must reflect molecular disease processes of importance in patients. Herein we characterized inflammation in NASH patients on the molecular level by transcriptomics and investigated whether key human disease pathways can be recapitulated experimentally in Ldlr -/- .Leiden mice, an established pre-clinical model of NASH. Methods: Human molecular inflammatory processes were defined using a publicly available NASH gene expression profiling dataset (GSE48452) allowing the comparison of biopsy-confirmed NASH patients with normal controls. Gene profiling data from high-fat diet (HFD)-fed Ldlr -/- .Leiden mice (GSE109345) were used for assessment of the translational value of these mice. Results: In human NASH livers, we observed regulation of 65 canonical pathways of which the majority was involved in inflammation (32%), lipid metabolism (16%), and extracellular matrix/remodeling (12%). A similar distribution of pathways across these categories, inflammation (36%), lipid metabolism (24%) and extracellular matrix/remodeling (8%) was observed in HFD-fed Ldlr -/- .Leiden mice. Detailed evaluation of these pathways revealed that a substantial proportion (11 out of 13) of human NASH inflammatory pathways was recapitulated in Ldlr -/- .Leiden mice. Furthermore, the activation state of identified master regulators of inflammation (i.e., specific transcription factors, cytokines, and growth factors) in human NASH was largely reflected in Ldlr -/- .Leiden mice, further substantiating its translational value. Conclusion: Human NASH is characterized by upregulation of specific

    Full Text Available Many curriculums assume that the new generation of students are digital natives and information literate. However, studies show that this is not often the case. From these studies and our own experiences working with multidisciplinary students in the Health Sciences we found that students were not as information literate as required in the curriculum. Using Design Based Research as a method (following the four phases below, we developed a new information search process and a web-based tool with feedback opportunities from teachers and librarians in order to qualify the students competencies. Problem identification: Despite earlier initiatives from library and department, the students didn’t achieve higher levels of information literacy. Prototyping: Requirements and educational material were merged and tested while gathering feedback. Iterations: The prototype and feedback were evaluated and developed into a new information search process, which was tested and evaluated. Reflection and generalization: Initiative was taken to develope a web-based application visualizing the steps with the learning points: self-feedback, peer-feedback and counselor feedback. The result of the project is a new information search process model and a web-based learning environment called B!NKO 2.0. The evaluations have shown positive feedback on both the process and the web tool. The project has opened up new possibilities that go beyond the Health multidisciplinary students. A new project concerning the Humanities and Social Sciences is incipient. In this project new functionalities are also expected. B!NKO 2.0 has to a great extent shown its worth to help Health multidisciplinary students to get a deeper understanding of information literacy, and how to develop and change searches to get better results. B!NKO 2.0 has also given a positive "side effect” on the librarians work. Time spend on the "Book a Librarian” service have decreased for the librarians using

  4. How to determine decisional capacity in critically ill patients. Presume the patient can make decisions unless proven otherwise.

    Decisional capacity includes ability to comprehend information, to make an informed choice, and to communicate that choice; it is specific to the decision at hand. Presume a patient has decisional capacity; an evaluation of incapacity must be justified. Administer a standardized mental status test to help assess alertness, attention, memory, and reasoning ability. A patient scoring below 10 on the Folstein Mini-Mental State Examination (maximum score, 30) probably does not have decisional capacity; one scoring from 10 to 15 probably can designate a proxy but not make complex health care decisions. Obtain psychiatric consultations for a patient who exhibits psychological barriers to decision making.

    In this article we present preliminary findings from a research program designed to investigate the value of alliance-focused training (AFT), a supervision approach designed to enhance therapists' ability to work constructively with negative therapeutic process. In the context of a multiple baseline design, all therapists began treating their patients using cognitive therapy and then joined AFT supervision groups at either session 8 or 16 of a 30 session protocol. Study I investigated the impact of AFT on patient and therapist interpersonal process as assessed through the Structural Analysis of Social Behavior (SASB). Study 2 investigated the impact of AFT on therapists' tendency to reflect on their relationships with their patients in an experientially grounded fashion, as assessed via the Experiencing Scale (EXP). Since one of the goals of AFT is to train therapists to use their own emerging feelings as important clues regarding what may be taking place in the therapeutic relationship, we hypothesized that they would show increased levels of EXP after undergoing AFT. The results of both studies 1 and 2 were for the most part consistent with hypotheses. Implications and future research directions are discussed.

    Peptide profiles of different drinking milk samples were examined to study how the peptide fingerprint of milk reflects processing conditions. The combination of a simple and fast method for peptide extraction using stage tips and MALDI-TOF-MS enabled the fast and easy generation and relative quantification of peptide fingerprints for high-temperature short-time (HTST), extended shelf life (ESL) and ultra-high temperature (UHT) milk of the same dairies. The relative quantity of 16 peptides changed as a function of increasing heat load. Additional heating experiments showed that among those, the intensity of peptide β-casein 196-209 (m/z 1460.9Da) was most heavily influenced by heat treatment indicating a putative marker peptide for milk processing conditions. Storage experiments with HTST- and UHT milk revealed that the differences between different types of milk samples were not only caused by the heating process. Relevant was also the proteolytic activity of enzymes during storage, which were differently influenced by the heat treatment. These results indicate that the peptide profile may be suitable to monitor processing as well as storage conditions of milk. In the present study, peptide profiling of different types of milk was carried out by MALDI-TOF-MS after stage-tip extraction and relative quantification using an internal reference peptide. Although MALDI-TOF-MS covers only part of the peptidome, the method is easy and quick and is, therefore, suited for routine analysis to address several aspects of food authenticity. Using this method, 16 native peptides were detected in milk that could be modulated by different industrial processes. Subsequent heating and storage experiments with pasteurized and UHT milk confirmed that these peptides are indeed related to the production or storage conditions of the respective products. Furthermore, the heating experiments revealed one peptide, namely the β-casein-derived sequence β-casein 196-209, which underwent

    2017-09-01

    User-generated information on the Internet provides opportunities for the monitoring of health information consumer attitudes. For example, information about cancer prevention may cause decisional conflict. Yet posts and conversations shared by health information consumers online are often not readily actionable for interpretation and decision-making due to their unstandardized format. This study extends prior research on the use of natural language as a predictor of consumer attitudes and provides a link to decision-making by evaluating the predictive role of uncertainty indicators expressed in natural language. Analyzed data included free-text comments and structured scale responses related to information about skin cancer prevention options. The study identified natural language indicators of uncertainty and showed that it can serve as a predictor of decisional conflict. The natural indicators of uncertainty reported here can facilitate the monitoring of health consumer perceptions about cancer prevention recommendations and inform education and communication campaign planning and evaluation.

  12. The Transference of Gender-based Norms in the Law Reform Process: A Reflection on my Work in Thailand

    Directory of Open Access Journals (Sweden)

    Y-Vonne Hutchinson

    2013-04-01

    Full Text Available In 2008, I spent a year as a Rule of Law specialist in Thailand with the International Rescue Committee (IRC, as part of a fellowship program for human rights lawyers. I was assigned the task of facilitating the development of a comprehensive legal code for the refugee camps along the border between Thailand and /Burma. As part of my work, I also sought to increase gender-based protection under the law through the incorporation of Thai and international human rights norms. This paper is a reflection on the processes that occurred during my time at IRC. The reform project approached the transference of contentious international norms for protection of women and girls in two ways: a through the inclusive design of the law reform process and b the establishment of a prohibition on rules that clearly violated international or national law. By forming a representative drafting committee and placing an emphasis on community consultation as a precursor to code finalisation, refugee perspectives, particularly female perspectives, were given scope to inform interpretations of national and international legal standards. By requiring international and national legal compliance and placing an emphasis on explanation and clarification of international and national standards in discussions, the project supported downward transference of international norms to a specific community context. We hoped that, as a product of these two normative flows, the resulting legal code would be a sustainable mechanism for gender-based protection and redress in cases of sexual and gender-based violence. During negotiations, it became evident that the inclusive design of the law reform process had a more positive impact on the success of norms transference than the actual substance of the norm. The norms that were most readily accepted were those introduced by law reform committee members themselves. Local norm translators played a pivotal role in the norms diffusion process

  13. Regulating Emotions during Difficult Multiattribute Decision Making: The Role of Pre-Decisional Coherence Shifting.

    Science.gov (United States)

    Carpenter, Stephanie M; Yates, J Frank; Preston, Stephanie D; Chen, Lydia

    2016-01-01

    Almost all real-life decisions entail attribute conflict; every serious choice alternative is better than its competitors on some attribute dimensions but worse on others. In pre-decisional "coherence shifting," the decision maker gradually softens that conflict psychologically to the point where one alternative is seen as dominant over its competitors, or nearly so. Specifically, weaknesses of the eventually chosen alternative come to be perceived as less severe and less important while its strengths seem more desirable and significant. The research described here demonstrates that difficult multiattribute decision problems are aversive and that pre-decisional coherence shifting aids individuals in regulating that emotional discomfort. Across three studies, attribute conflict was confirmed to be aversive (Study 1), and skin conductance responses and ratings of decision difficulty both decreased in participants who coherence shifted (Study 2). Coherence shifting was also diminished among decision makers who were depleted of regulatory resources, known to be required for common emotion regulation mechanisms. Further, coherence shifting was shown to be relatively common among people who reported strong suppression tendencies in everyday emotion regulation (Study 3). Overall, the data suggest that, at least in part, coherence shifting serves as a tool that helps decision makers manage the pre-decisional discomfort generated by attribute conflict. Theoretical and practical implications are discussed.

    The decisional balance (DB) procedure examines the pros and cons of behavior change and was considered a component in early formulations of Motivational Interviewing (MI). However, there is controversy and conflicting findings regarding the use of a DB exercise within the treatment of addictions and a need to clarify the role of DB as a component of MI. College tobacco smokers (N=82) with no intentions on quitting were randomly assigned to receive a single counseling session of either Motivational Interviewing using only the decisional balance component (MIDB), or health education around smoking cessation (HE). Assessments were obtained at baseline, immediately post-treatment, 1week, and 4weeks. Compared to HE, the MIDB sessions scored significantly higher on the Motivational Interviewing Treatment Integrity (MITI) scale (all standardized differences d>1, pmotivation to quit, quit attempts, and self-reported abstinence, with no significant group differences. Changes in the Pros of smoking were correlated with MITI scores, but not with cessation outcomes. In contrast, increases in the Cons of smoking and therapeutic alliance were predictive of better cessation outcomes. The decisional balance exercise as formulated by earlier versions of MI may be counter-productive and cautions around its use are warranted. Instead, improved cessation outcomes appear associated with increasing perceived benefits of quitting and positive therapeutic alliance. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available The Campanian volcanism develops near the sea. Therefore, the geophysical study of the marine environment is a key to a better understanding of the tectonic evolution and the origin of volcanism in the area. An abundance of high quality seismic data in the marine sector, where little direct information is available, is critical to the study of Campanian volcanism. This paper concerns the reprocessing of a seismic reflection dataset acquired in Naples Bay and processed during 1973. Even though the overall data quality was high for that time, of course their acquisition technological limits have been overcome by the new processing. Our reprocessing aimed at: 1 reduction of random noise in the data; 2 removal of unwanted coherent events; 3 reduction of spatial aliasing by means of trace interpolation on Commod Shot Point (CSP gathering; 4 improvement of resolution of the seismic wavelet with spiking deconvolution algorithms and finally 5 reposition of reflectors in their correct locations in the space-TWT domain by means of dip moveout and post-stack time migration. A comparison between the new and old data shows that the new sections are characterized by a much higher S/N ratio. Diffraction hyperbole has been collapsed. Reverberations, ghosts and multiples have been removed or greatly attenuated, especially between the reflectors of interest, allowing us to follow them with more detail and with greater continuity. Furthermore, data resolution has been boosted by the reprocessing, allowing the interpreter to evaluate reflector position and continuity in greater detail. The reinterpretation phase of such lines, that is already in an advanced stage, will therefore allow us to gain new insights into the structural setting of the bay, with the aim of exploring the connection between tectonics and volcanism.

    Full Text Available Tomar decisiones es algo común en nuestra vida y contribuye a la adaptación al medio en que vivimos, por ello es relevante conocer cómo es el proceso de toma de decisiones y las posibles disfunciones que puedan darse a causa de su deterioro. En el caso de los pacientes con demencia tipo Alzheimer, los problemas en la toma de decisiones parecen incluso ya en fases leves, lo que dificulta la correcta interacción con el entorno, especialmente en situaciones de incertidumbre. Este proceso ha sido analizado desde varios enfoques, siendo la hipótesis del marcador somático y la tarea de la Iowa Gambling Task (IGT uno de los más utilizados. El objetivo de este trabajo es el de analizar la toma de decisiones en pacientes con DTA frente a un grupo de sujetos control, y analizar el tipo de elecciones de ambos grupos en situaciones de incertidumbre mediante la una versión modificada de la IGT, observar si son tendentes al riesgo o no, y la relación que guarda su ejecución con el status cognitivo en cada una de las áreas evaluadas por los tests. Además de la IGT, utilizaremos como test de cribado en demencias el Miniexamen Cognoscitivo de Lobo, Test del Reloj a la Orden y Copia y Test de Fluidez Verbal de Isaacs. En nuestros resultados, los sujetos con DTA presentan una ejecución deficitaria en la IGT, tanto en el cómputo global como en su análisis por bloques, con una estrategia de elección de cartas aleatoria, por lo que podríamos considerar ciertas tendencias al riesgo, si bien su ejecución muestra cierta capacidad de aprendizaje a lo largo de los bloques. Por último, el deterioro cognitivo y el grado de afectación en las distintas áreas analizadas se relacionan con la forma en que toman decisiones los pacientes con DTA.

    Systems and methods for calculating L* in the magnetosphere with essentially the same accuracy as with a physics based model at many times the speed by developing a surrogate trained to be a surrogate for the physics-based model. The trained model can then beneficially process input data falling within the training range of the surrogate model. The surrogate model can be a feedforward neural network and the physics-based model can be the TSK03 model. Operatively, the surrogate model can use parameters on which the physics-based model was based, and/or spatial data for the location where L* is to be calculated. Surrogate models should be provided for each of a plurality of pitch angles. Accordingly, a surrogate model having a closed drift shell can be used from the plurality of models. The feedforward neural network can have a plurality of input-layer units, there being at least one input-layer unit for each physics-based model parameter, a plurality of hidden layer units and at least one output unit for the value of L*.

  1. Hydrogen isotope analysis of amino acids and whole cells reflects biosynthetic processing of nutrient- and water-derived hydrogen

    Hydrogen (H) isotopes serve as sensitive tracers of biochemical processes that can be exploited to answer critical questions in biogeochemistry, ecology, and microbiology. Despite this apparent utility, relatively little is known about the specific mechanisms of H isotope fractionation involved in biosynthesis. In order to understand how organisms incorporate hydrogen from their chemical milieu into biomass, we have cultured the model bacterium E. coli MG1655 in a variety of media composed of deuterium-labeled nutrients and waters. Isotopic analysis of bulk cell mass reveals that the H fractionation between media water and cell material varies as a function of the nutrient source, with commonly used organic food sources (glucose and tryptone) leading to far smaller fractionation signals than non-standard ones (such as formamide, adenine, and urea). In addition, we have completed compound specific isotope analysis of amino acids using combined GC-IRMS. Amino acids harvested from E. coli cultured on glucose in water of varied D/H composition posses an extraordinary range of isotopic compositions (400-600 %). Furthermore, these amino acids follow a systematic distribution of D/H where proline is always heaviest and glycine is always lightest. However, when the short-chain peptide tryptone is used in place of glucose, only the non-essential amino acids reflect media water D/H values, suggesting the direct incorporation of some media-borne amino acids into cellular protein. These observations provide a foundation for understanding the cellular routing of hydrogen obtained from food and water sources and indicate that D/H analysis can serve as a powerful probe of biological function.

    Reflective writing in medical training has been shown to be most effective when combined with some form of personal meeting or dialog. During a course in medical psychology for medical students, reflective texts were followed up by an individual personal talk with a teacher from the course. Thematic analysis of the texts revealed four separate sub-themes: 1) the course has enabled me and the class to develop, which is good albeit arduous; 2) understanding myself is a resource in understanding people as well as knowing psychology; 3) the course provided me with new, purely intellectual skills as well as eye-openers; and 4) the receiving teacher is an integral part of my reflective writing. The main theme, capturing the students' writing process, concluded that students perceive the course as "Learning psychology as a challenging process towards development" as well as "studies as usual". Ethical, psychological, and pedagogical aspects are discussed in the paper.

    Shared decision making (SDM) has been advocated as an approach to medical decision making that can improve decisional quality. Decision aids are tools that facilitate SDM in the context of limited physician time; however, many decision aids do not incorporate preference measurement. We aim to understand whether adding preference measurement to a standard patient educational intervention improves decisional quality and is feasible in a busy clinical setting. Men with incident localized prostate cancer (n = 122) were recruited from the Greater Los Angeles Veterans Affairs (VA) Medical Center urology clinic, Olive View UCLA Medical Center, and Harbor UCLA Medical Center from January 2011 to May 2015 and randomized to education with a brochure about prostate cancer treatment or software-based preference assessment in addition to the brochure. Men undergoing preference assessment received a report detailing the relative strength of their preferences for treatment outcomes used in review with their doctor. Participants completed instruments measuring decisional conflict, knowledge, SDM, and patient satisfaction with care before and/or after their cancer consultation. Baseline knowledge scores were low (mean 62%). The baseline mean total score on the Decisional Conflict Scale was 2.3 (±0.9), signifying moderate decisional conflict. Men undergoing preference assessment had a significantly larger decrease in decisional conflict total score (p = 0.023) and the Perceived Effective Decision Making subscale (p = 0.003) post consult compared with those receiving education only. Improvements in satisfaction with care, SDM, and knowledge were similar between groups. Individual-level preference assessment is feasible in the clinic setting. Patients with prostate cancer who undergo preference assessment are more certain about their treatment decisions and report decreased levels of decisional conflict when making these decisions.

    Directory of Open Access Journals (Sweden)

    Inés Ma. Barrio Cantalejo

    2006-01-01

    Full Text Available Actualmente las relaciones sanitarias se apoyan en el reconocimiento del derecho de los pacientes a participar en las decisiones sobre su salud. Esta idea es el fundamento del consentimiento informado. Sin embargo, problema surge cuando el paciente no puede participar en estas decisiones porque se halla en una situación de incapacidad. Es otro, un representante, quien debe decidir por él. En España no existe claridad sobre qué criterios deben orientar las decisiones que ha de tomar el representante. El presente artículo presenta los criterios de decisión en pacientes incapaces desarrollados por la jurisprudencia norteamericana: el criterio subjetivo, el criterio del juicio sustitutivo y el criterio del mejor interés o mayor beneficio. El criterio subjetivo consiste en seguir las directrices que el paciente dictó antes de perder la capacidad. El criterio del juicio sustitutivo trata de deducir la decisión que hubiese tomado el propio paciente si pudiera, a partir de lo que conocemos de él. El criterio del mayor beneficio intenta proteger el bienestar del paciente. Tradicionalmente el «mejor interés» ha sido defender la vida a toda costa, sin atender a otro tipo de consideraciones. Quizás sea el momento de buscar un consenso sobre lo que socialmente hoy en día se considera «mejor interés». Su significado no podrá derivarse exclusivamente del derecho a la vida, sino de la conjunción entre éste –en cantidad y calidad suficientes– y la libertad, interpretados a la luz del respeto a la dignidad de la persona.

  12. The neural evidence of the reflected appraisal process as a main path for learning about one's self-knowledge of personality.

    Self-knowledge has been defined as the accurate self-perceptions about how one typically thinks, feels, and behaves, and awareness of how those patterns are interpreted by others. Previous research has noted that the introspection and the reflected appraisal processes are two main avenues for learning about the self and that self-knowledge might be fully realized through the use of reflected appraisal from close others. However, due to the methodological difficulty in linking people's ratings on a trait to their behaviors, accuracy research using a behavioral criterion is quite limited. The current work examined the main source of learning about one's self-knowledge by investigating the time course of attention deployment both in the process of introspection and that of reflected appraisal. Twenty-five college students were first asked to rate their impressions of their classmates as well as a familiar other using personality-trait adjectives. Their electrophysiological data were then collected using the event-related potential (ERP) technology while they judged to which extent (1) an adjective can describe the self, (2) an adjective can describe a familiar other, (3) they agree with an adjective that their classmates believe can describe the self, and (4) they agree with an adjective that their classmates believe can describe a familiar other. Our electrophysiological data showed that classmates' positive evaluation of one's own trait elicited larger P2 than the positive self-evaluation of one's own trait. Further, classmates' negative evaluation of one's own trait elicited larger late positive component (LPC) than the negative self-evaluation of one's own trait. Results suggest that people allocate more attention to the process of reflected appraisal compared to the process of introspection, which further suggests that the reflected appraisal process might be the main source in learning about one's self-knowledge of personality.

Se constató para cada uno de los escenarios planteados en el ejercicio la existencia de equilibrios perfectos en subjuegos en el sentido de Nash, que permitieron develar que la condición de racionalidad maximizadora de los jugadores es el elemento principal a la hora de la toma de decisiones al interior de grupos sociales. Por último, la observación puso en evidencia que las interacciones entre dos agentes están condicionadas por las estrategias que adopte el agente que opere de líder, y que las decisiones del agente seguidor regularmente se basan en criterios cooperativos y de coordinación; en este sentido, se pudo establecer que el Banco de la República determina la manera en la que el Gobierno, respetando los conductos constitucionales, toma sus decisiones de política con el #n de mantener la estabilidad económica del país.

En primer lugar realizaremos una descripción general del contexto de los casos de aborto no punible en la Argentina, resaltando que en la mayoría de los casos las creencias religiosas de los expertos suelen influir y condicionar las decisiones de las mujeres. Luego, pondremos el foco en la discusión dentro de un comité sobre un caso particular, el de una joven discapacitada que solicitó un aborto luego de un abuso sexual y que luego de atravesar un largo camino de judicialización y evaluaciones de comités de expertos, no logró interrumpir su embarazo. Este caso ilustra cómo las creencias religiosas influencian la toma de decisiones en el área de la salud pública y cómo se consolida la presencia de agentes religiosos expertos en bioética como una estrategia para influenciar los espacios públicos de la Iglesia Católica en la Argentina.

    Full Text Available El modelo de atención en salud paternalista está derivando hacia modelos más participativos, como lo es la toma de decisiones compartidas (TDC, en el que se considera al paciente como agente responsable y autónomo. La TDC representa un enfoque terapéutico en el que profesionales y pacientes comparten la mejor evidencia científica disponible para tomar una decisión, incorporando los valores y preferencias del paciente. Este intercambio de información puede facilitarse mediante el uso de herramientas de ayuda para la TDC, que han demostrado ser efectivas para mejorar el conocimiento, la satisfacción del paciente, y reducir el conflicto decisional. En este sentido, las habilidades comunicacionales ejercen un rol fundamental en el establecimiento de la relación profesional - paciente, facilitando el intercambio de información y preferencias de manera efectiva y respetuosa. Esta aproximación terapéutica podría apoyar la reducción de las disparidades en salud que prevalecen en Latinoamérica, al facilitar que las personas puedan participar informada y activamente en el cuidado de su salud.

    Studies of determinants of adoption of new medical technology have failed to coalesce into coherent knowledge. A flaw obscuring strong patterns may be a common habit of treating a wide range of health care innovations as a generic technology. We postulate three decisional systems that apply to different medical technologies with distinctive expertise, interest, and authority: medical-individualistic, fiscal-managerial, and strategic-institutional decisional systems. This review aims to examine the determinants of the adoption of medical technologies based on the corresponding decision-making system. We included quantitative and qualitative studies that analyzed factors facilitating or inhibiting the adoption of medical technologies. In total, 65 studies published between 1974 and 2014 met our inclusion criteria. These studies contained 688 occurrences of variables that were used to examine the adoption decisions, and we subsequently condensed these variables to 62 determinants in four main categories: organizational, individual, environmental, and innovation-related. The determinants and their empirical association with adoption were grouped and analyzed by the three decision-making systems. Although we did not identify substantial differences across the decision-making systems in terms of the direction of the determinants' influence on adoption, a clear pattern emerged in terms of the categories of determinants that were targeted in different decision-making systems.

    Increasing public commitment to organ donation is critical to improving donor kidney availability for end-stage renal disease patients desiring transplant. This study surveyed ( N = 1339) African Americans, measuring perceived pros relative to cons of organ donation, to evaluate an existing Transtheoretical Model decisional balance scale and associations between decisional balance and expressing donation intentions. Findings supported the existing scale structure. More positive decisional balance ratios were associated with 1.76 times the odds of expressing intentions (95% confidence interval = 1.52-2.04). Pros were more strongly linked to donation intentions than cons. Greater understanding of organ donation decision-making is valuable for informing interventions that encourage donation.

    Full Text Available Education for youngsters and adults (in Spanish, EPJA has reached prominence in the Chilean educational system. It has had to give a new chance to a large number of young people who, for one reason or another, did not complete their studies in traditional training. In this scenario, it explores pedagogical practices developed by teachers working with youngsters and adults, especially those who refer to learning assessment. Therefore, the purpose of this study is to present the results of a reflection carried out by a group of teachers from a comprehensive adult education center, in order to improve their practices to evaluate their students’ learning. The research model is based on the qualitative approach with a case study design. It makes a comprehensive diagnostic of teaching practices, conducted through discussion groups. The analysis of the results shows that most teachers working at this educational center follow traditional assessment practices. They tend to copy conceptions of assessment centered around products that can be scored in order to check goal achievement, rather than around providing feedback that promotes self-regulated learning. However, the reflection also shows that teachers are willing to participate in pedagogical reflection sessions that guide them to improve their assessment practices.

During a course in medical psychology for medical students, reflective texts were followed up by an individual personal talk with a teacher from the course. Thematic analysis of the texts revealed four separate sub-themes: 1 the course has enabled me and the class to develop, which is good albeit arduous; 2 understanding myself is a resource in understanding people as well as knowing psychology; 3 the course provided me with new, purely intellectual skills as well as eye-openers; and 4 the receiving teacher is an integral part of my reflective writing. The main theme, capturing the students’ writing process, concluded that students perceive the course as “Learning psychology as a challenging process towards development” as well as “studies as usual”. Ethical, psychological, and pedagogical aspects are discussed in the paper. Keywords: reflective writing, self-knowledge, individual personal talks, thematic analysis, medical education

    Patients with complex care needs (PCCNs) often suffer from combinations of multiple chronic conditions, mental health problems, drug interactions and social vulnerability, which can lead to healthcare services overuse, underuse or misuse. Typically, PCCNs face interactional issues and unmet decisional needs regarding possible options in a cascade of interrelated decisions involving different stakeholders (themselves, their families, their caregivers, their healthcare practitioners). Gaps in knowledge, values clarification and social support in situations where options need to be deliberated hamper effective decision support interventions. This review aims to (1) assess decisional needs of PCCNs from the perspective of stakeholders, (2) build a taxonomy of these decisional needs and (3) prioritise decisional needs with knowledge users (clinicians, patients and managers). This review will be based on the interprofessional shared decision making (IP-SDM) model and the Ottawa Decision Support Framework. Applying a participatory research approach, we will identify potentially relevant studies through a comprehensive literature search; select relevant ones using eligibility criteria inspired from our previous scoping review on PCCNs; appraise quality using the Mixed Methods Appraisal Tool; conduct a three-step synthesis (sequential exploratory mixed methods design) to build taxonomy of key decisional needs; and integrate these results with those of a parallel PCCNs' qualitative decisional need assessment (semistructured interviews and focus group with stakeholders). This systematic review, together with the qualitative study (approved by the Centre Intégré Universitaire de Santé et Service Sociaux du Saguenay-Lac-Saint-Jean ethical committee), will produce a working taxonomy of key decisional needs (ontological contribution), to inform the subsequent user-centred design of a support tool for addressing PCCNs' decisional needs (practical contribution).

    As part of an ongoing study, seismic-reflection profiles were collected over the Blake Ridge in 1992 and 1995, in order to map the volume and distribution of methane hydrate. Faulting and seafloor instabilities appear to be related to methane hydrate processes at the Blake Ridge. Seismic profiles display a prominent collapse structure at the crest, which is inferred to have resulted from the mobilization of sediment that was associated with methane hydrate dissociation.

    A photovoltaic module includes colorized reflective photovoltaic cells that act as pixels. The colorized reflective photovoltaic cells are arranged so that reflections from the photovoltaic cells or pixels visually combine into an image on the photovoltaic module. The colorized photovoltaic cell or pixel is composed of a set of 100 to 256 base color sub-pixel reflective segments or sub-pixels. The color of each pixel is determined by the combination of base color sub-pixels forming the pixel. As a result, each pixel can have a wide variety of colors using a set of base colors, which are created, from sub-pixel reflective segments having standard film thicknesses.

Although knowledge about stroke warning signs and risk factors has received considerable attention, objective knowledge on secondary prevention and further self-esteem subjective knowledge have rarely been studied. The aim of our study was to investigate knowledge and treatment decisional role preferences in cerebrovascular patients compared to controls. Methods: We performed a survey on subjective and objective stroke risk knowledge and autonomy preferences in cerebrovascular patients from our stroke outpatient clinic (n=262 and from pedestrians on the street taken as controls during a “World Stroke Day” (n=274. The questionnaire includes measures for knowledge and decisional role preferences from previously published questionnaires and newly developed measures, for example, subjective knowledge, revealed on a visual analog scale. Results: The overall stroke knowledge was low to moderate, with no differences between patients and controls. Knowledge about secondary prevention was particularly low. Only 10%–15% of participants correctly estimated the stroke absolute risk reduction potential of aspirin. The medical data

    2009-06-01

    The authors examined the prevalence of chronic procrastination (decisional, avoidant, and arousal styles) as functions of demographic variables among 354 Turkish adults (148 men, 206 women; M age = 38.7 years, SD = 8.26 years). Prevalence analyses showed that among Turkish participants, 17.5% were indecisive procrastinators, 13.8% were avoidant procrastinators, and 14.7% were arousal procrastinators. Results did not yield significant differences for gender or age on any forms of procrastination, which is consistent with other international samples. However, significant differences emerged depending on the number of children such that Turkish adults who had more than 3 children claimed to be more indecisive than they claimed to be arousal or avoidant procrastinators. Respondents with less than a graduate degree reported higher rates of indecision than did respondents with at least a graduate degree.

  1. Optimización en las decisiones de financiamiento de proyectos

    2003-07-01

    Full Text Available La finalidad de este trabajo es aplicar herramientas de optimización a las decisiones de financiamiento de proyectos de inversión, más específicamente, cómo mejorar el valor actual de un proyecto eligiendo la combinación óptima de fuentes de financiamiento. El carácter de largo plazo de las inversiones de un proyecto exige investigar las opciones de financiamiento para el proyecto, y no cabe duda que mientras más convenientes sean las condiciones que se logren, más atractivo será el proyecto. La búsqueda de la forma de financiar un proyecto de inversión, puede dar como resultado una variedad bastante importante de opciones diferentes. Esta información es de mucha utilidad para el inversionista, porque le permite determinar cómo financiar el proyecto, es decir, cuánto capital propio debe invertir en el proyecto y cómo debe financiar el monto restante de la inversión. Los métodos y modelos que se usan actualmente en esta toma de decisiones tienen deficiencias. Una de las deficiencias más importantes de estos métodos es que suponen que en todos los periodos se tienen utilidades antes de impuestos, calculando impuestos sobre las pérdidas antes de impuesto. También presentan dificultades cuando se tienen muchas alternativas de financiamiento y no permiten buscar combinaciones entre fuentes de financiamiento. A medida que aumenta la cantidad y características de las fuentes de financiamiento, aumenta la cantidad de cálculos de valor actual que se deben realizar, por lo que la aplicación de estas herramientas requiere una gran cantidad de tiempo. Para resolver el problema se recurrió a la teoría económica de Preparación de Proyectos, Evaluación de Proyectos y Programación Matemática, más específicamente a la Programación Mixta, que es una mezcla de Programación Lineal y Programación Entera. El procedimiento que se empleó para desarrollar el modelo de programación matemática, comenzó con la identificación de

Los entornos hostiles se caracterizan por la presencia de amenazas, modeladas aquí como radares. Inicialmente se planifica una ruta. Si en vuelo surgen nuevas amenazas, la ruta inicial se replanifica. En ambos casos las rutas se obtienen mediante el algoritmo A*. Ante una replanificación el UAV toma una decisión sobre si continuar por la ruta inicial o por la replanificada. La teoría de la decisión multiatributo proporciona en este caso el mecanismo adecuado.

    Full Text Available The 8-item Decisional Balance for sun protection inventory (SunDB assesses the relative importance of the perceived advantages (Pros and disadvantages (Cons of sun protective behaviors. This study examined the psychometric properties of the SunDB measure, including invariance of the measurement model, in a population-based sample of N=1336 adults. Confirmatory factor analyses supported the theoretically based 2-factor (Pros, Cons model, with high internal consistencies for each subscale (α≥.70. Multiple-sample CFA established that this factor pattern was invariant across multiple population subgroups, including gender, racial identity, age, education level, and stage of change subgroups. Multivariate analysis by stage of change replicated expected patterns for SunDB (Pros η2=.15, Cons η2=.02. These results demonstrate the internal and external validity and measurement stability of the SunDB instrument in adults, supporting its use in research and intervention.

    Full Text Available La contabilidad de costos ha adquirido un papel fundamental dentro de las organizaciones modernas, considerándose una herramienta valiosa en el control y la toma de decisiones estratégi- cas, utilizando para ello nuevas técnicas, tales como el costeo basado en actividades (ABC y el en- foque de la cadena de valor, a través de los cuales se controlan las actividades desempeñadas en los procesos y se logra el entendimiento del comportamiento de los costos. En este sentido se seleccio- nó el proceso de pesca del atún para identificar las actividades que intervienen en el mismo y dife- renciar aquellas que agregan o no valor al producto. Se tomó como muestra un barco atunero, por el método del muestreo aleatorio al azar simple, para garantizar la representatividad de la misma. El estudio se realizó aplicando técnicas de recolección de información, tales como la entrevista y la ob- servación directa. Con la identificación de actividades se espera que la empresa encargada del pro- ceso de pesca del atún pueda realizar un mejor control de estas y alcanzar un nivel de desempeño por actividad, a la vez que permita la planificación de las mismas. Se determinó además las actividades que no agregan valor, en las cuales se pueden lograr reducciones de costos.

  7. Disruption of visual awareness during the attentional blink is reflected by selective disruption of late-stage neural processing

    Any information represented in the brain holds the potential to influence behavior. It is therefore of broad interest to determine the extent and quality of neural processing of stimulus input that occurs with and without awareness. The attentional blink is a useful tool for dissociating neural and behavioral measures of perceptual visual processing across conditions of awareness. The extent of higher-order visual information beyond basic sensory signaling that is processed during the attentional blink remains controversial. To determine what neural processing at the level of visual-object identification occurs in the absence of awareness, electrophysiological responses to images of faces and houses were recorded both within and outside of the attentional blink period during a rapid serial visual presentation (RSVP) stream. Electrophysiological results were sorted according to behavioral performance (correctly identified targets versus missed targets) within these blink and non-blink periods. An early index of face-specific processing (the N170, 140–220 ms post-stimulus) was observed regardless of whether the subject demonstrated awareness of the stimulus, whereas a later face-specific effect with the same topographic distribution (500–700 ms post-stimulus) was only seen for accurate behavioral discrimination of the stimulus content. The present findings suggest a multi-stage process of object-category processing, with only the later phase being associated with explicit visual awareness. PMID:23859644

    Full Text Available El propósito de este estudio fue obtener una más clara comprensión del proceso de toma de decisiones en estudiantes de Enfermería que van a recibir su licenciatura, durante el cuidado de los pacientes. Se empleó un diseño descriptivo cualitativo, basado en preguntas abiertas semi-estructuradas, con el fin de recolectar información acerca de las decisiones, culturalmente diversas, tomadas por las estudiantes de Enfermería durante el cuidado de pacientes adultos, en una variedad de situaciones clínicas. Los temas que surgieron incluyen capacidad de comunicación, conocimiento, heroísmo, ansiedad y frustración. Los descubrimientos hallados indican que los estudiantes se propusieron metas en forma recíproca a todo lo largo del proceso de toma de decisiones. El autor empleó la teoría de la consecución de metas, de Imogene King, para interpretar los descubrimientos de este estudio y relacionar la teoría con la práctica. La toma de decisiones clínicas es un punto importante dentro de la educación y práctica de la Enfermería. La Facultad, entendiendo qué son los procesos de pensamiento, se anticipa con un diseño de estrategias específicas que refuerzan el razonamiento en la práctica clínica. Una parte de este proceso es ayudar a los estudiantes a salir de la dependencia que generan cuando quieren memorizar la información contenida en los textos, y hacerlos avanzar hacia la aplicación de los conceptos provenientes, tanto de las artes liberales, como de las ciencias biológicas y de Enfermería. Se trata de un especial desafío para las facultades y personal docente de Enfermería encargado de impartir educación a los estudiantes de la carrera, así como para el recién egresados de otras áreas de formación y de experiencia. Los resultados de estudios anteriores sobre toma de decisiones clínicas presentan conclusiones conflictivas e inconclusas, concernientes a determinadas consecuencias predecibles y otros factores

    Full Text Available The Colegio Pedro II was equated to Federal Institutes of Education, Science and Technology by Law 12677 Publication of June 25, 2012. If, on the one hand, this equalization resulted in an expressive organizational restructuring, with growth of the number of educational units, in addition to the incorporation of new educational levels, on the other, this institutional growth was dissociated from efforts of standardization of administrative processes, notably, under the academic departments of different units – where it shows a variation of the process of launching notes/concepts. In order to contribute with improvements to the operation of the institution, the present article aims to map and analyse comparatively the launch process of notes/concepts in three campus of the Colegio Pedro II. Methodologically, are held in-person interviews with professionals responsible for the academic departments of the following units, Engenho Novo I, Humaita I and Realengo I, in order to obtain the necessary subsidies to support the design of the processes performed by these academic departments units. As a result, it can be verified that the processes of the academic departments are not aligned to any system of performance indicators, which motivated the proposal of a standard process for the launching of notes/concepts, as well as a performance indicators panel (KPIs.

    HD 38563B, are the main powerhouses behind Messier 78. However, the nebula is home to many more stars, including a collection of about 45 low mass, young stars (less than 10 million years old) in which the cores are still too cool for hydrogen fusion to start, known as T Tauri stars. Studying T Tauri stars is important for understanding the early stages of star formation and how planetary systems are created. Remarkably, this complex of nebulae has also changed significantly in the last ten years. In February 2004 the experienced amateur observer Jay McNeil took an image of this region with a 75 mm telescope and was surprised to see a bright nebula - the prominent fan shaped feature near the bottom of this picture - where nothing was seen on most earlier images. This object is now known as McNeil's Nebula and it appears to be a highly variable reflection nebula around a young star. This colour picture was created from many monochrome exposures taken through blue, yellow/green and red filters, supplemented by exposures through an H-alpha filter that shows light from glowing hydrogen gas. The total exposure times were 9, 9, 17.5 and 15.5 minutes per filter, respectively. Notes [1] Igor Chekalin from Russia uncovered the raw data for this image of Messier 78 in ESO's archives in the competition Hidden Treasures (eso1102). He processed the raw data with great skill, claiming first prize in the contest for his final image (Flickr link). ESO's team of in-house image processing experts then independently processed the raw data at full resolution to produce the image shown here.

    Full Text Available Background: According to statistical evidence put forward by WHO in 2003, lack of physical activity is the reason for 1.9 million deaths in the world. More than 60% of adults in the world and more than 80% of Iranian adults do not perform sufficient levels of physical activity. Despite the great advantages of exercise a huge portion of the population of many countries do not exercise adequately thus deprived of its benefits. Transtheoretical model is identified as a comprehensive model for behavior change and decision balance is regarded as a fundamental structure of the model which centers around positive and negative behavior change consequences. In this study decision was made to check the situation of sport change process in Yazd’s staff according to Transtheoretical Model and its relation with decision balance.Materials and Methods: In this cross-sectional study, 220 subjects were recruited. The subjects were selected through 2-stage cluster sampling-test; the instruments for data collection were a questionnaire that consisted of two parts (demographic variables and construct of TTM. Data analyzed by ANOVA and T-test through SPSS and P<0.05 was significant.Results: Results of the study on 152 males (69.1% and 68 females (30.9% with the average age of 34±8.68 indicated a significant relationship between pros and cons with stages of change (both P<0.0001 and between pros with age (P=0.004.

Uno de los principios activos de la mariguana es el Δ9-tetrahidrocannabinol. Esta molécula afecta al sistema endocannabinoide, provocando cambios en su función y, concomitantemente, en la morfología cerebral. Objetivo: revisar y discutir la evidencia científica del efecto del consumo de mariguana sobre el cerebro, la inteligencia y la toma de decisiones. Método: se consideraron los reportes científicos que abarcan de 2005 a marzo de 2016 encontrados en PubMed, enfocados en los efectos del consumo de mariguana sobre cambios morfológicos cerebrales, la inteligencia y la toma de decisiones. Resultados: dependiendo de la edad de inicio del consumo de mariguana, es posible detectar cambios en el cerebro y la inteligencia, mientras que otras variables como la frecuencia o la cantidad de uso repercuten en la eficiencia para la toma de decisiones. Discusión y conclusiones: estos resultados señalan que 1 el consumo de mariguana afecta la morfología cerebral, la toma de decisiones y la inteligencia; 2 sugieren la potencial participación del sistema endocannabinoide en la toma de decisiones e inteligencia; y 3 dadas las consecuencias, deben alertar al sector salud para promover su prevención y en su momento estar preparados para la rehabilitación.

  19. Is restlessness best understood as a process? Reflecting on four boys’ restlessness during music therapy in kindergarten

    2017-01-01

    ABSTRACT ADHD can be considered an internationally recognized framework for understanding children’s restlessness. In this context, children’s restlessness is understood as a symptom of neurodevelopmental disorder. However, there are other possible understandings of children’s restlessness. In this article, we explore four boys’ collaborative and creative process as it is described and understood by three adults. The process is framed by a community music therapy project in a Norwegian kindergarten, and we describe four interrelated phases of this process: Exploring musical vitality and cooperation, Consolidating positions, Performing together, and Discovering ripple effects. We discuss these results in relation to seven qualities central to a community music therapy approach: participation, resource orientation, ecology, performance, activism, reflexivity and ethics. We argue that in contrast to a diagnostic approach that entails a focus on individual problems, a community music therapy approach can shed light on adult and systemic contributions to children’s restlessness.

    The development of the solonetzic process in paleosols buried under kurgans and in the modern surface soils has been studied on the basis of the analysis of the clay (memory“ of the solid-phase soil components. The mineralogical characteristics show that the solonetzic process in the modern background soil is more developed. The mineralogical approach allows us to reveal the long-term changes in the soil status; it is less useful for studying the effect of short-term bioclimatic fluctuations. In the latter case, more labile soil characteristics should be used. The mineralogical method, combined with other methods, becomes more informative upon the study of soil chronosequences. Our studies have shown that the data on the clay minerals in the buried paleosols may contain specific information useful for paleoreconstructions that is not provided by other methods.

    Despite the fact that physical health and cognitive abilities decline with aging, the ability to regulate emotion remains stable and in some aspects improves across the adult life span. Older adults also show a positivity effect in their attention and memory, with diminished processing of negative stimuli relative to positive stimuli compared with younger adults. The current paper reviews functional magnetic resonance imaging studies investigating age-related differences in emotional processing and discusses how this evidence relates to two opposing theoretical accounts of older adults’ positivity effect. The aging-brain model [Cacioppo et al. in: Social Neuroscience: Toward Understanding the Underpinnings of the Social Mind. New York, Oxford University Press, 2011] proposes that older adults’ positivity effect is a consequence of age-related decline in the amygdala, whereas the cognitive control hypothesis [Kryla-Lighthall and Mather in: Handbook of Theories of Aging, ed 2. New York, Springer, 2009; Mather and Carstensen: Trends Cogn Sci 2005;9:496–502; Mather and Knight: Psychol Aging 2005;20:554–570] argues that the positivity effect is a result of older adults’ greater focus on regulating emotion. Based on evidence for structural and functional preservation of the amygdala in older adults and findings that older adults show greater prefrontal cortex activity than younger adults while engaging in emotion-processing tasks, we argue that the cognitive control hypothesis is a more likely explanation for older adults’ positivity effect than the aging-brain model.

  11. Consciousness across Sleep and Wake: Discontinuity and Continuity of Memory Experiences As a Reflection of Consolidation Processes

    Directory of Open Access Journals (Sweden)

    Caroline L. Horton

    2017-09-01

    Full Text Available The continuity hypothesis (1 posits that there is continuity, of some form, between waking and dreaming mentation. A recent body of work has provided convincing evidence for different aspects of continuity, for instance that some salient experiences from waking life seem to feature in dreams over others, with a particular role for emotional arousal as accompanying these experiences, both during waking and while asleep. However, discontinuities have been somewhat dismissed as being either a product of activation-synthesis, an error within the consciousness binding process during sleep, a methodological anomaly, or simply as yet unexplained. This paper presents an overview of discontinuity within dreaming and waking cognition, arguing that disruptions of consciousness are as common a feature of waking cognition as of dreaming cognition, and that processes of sleep-dependent memory consolidation of autobiographical experiences can in part account for some of the discontinuities of sleeping cognition in a functional way. By drawing upon evidence of the incorporation, fragmentation, and reorganization of memories within dreams, this paper proposes a model of discontinuity whereby the fragmentation of autobiographical and episodic memories during sleep, as part of the consolidation process, render salient aspects of those memories subsequently available for retrieval in isolation from their contextual features. As such discontinuity of consciousness in sleep is functional and normal.

    When completed, the National Ignition Facility (NIF) will provide laser energies in the Mega-joule range. Successful pulse amplification to these extremely high levels requires that all small optics, found earlier in the beamline, have stringent surface and laser fluence requirements. In addition, they must operate reliably for 30 years constituting hundreds of thousands of shots. As part of the first four beamlines, spherical and aspherical lenses were required for the beam relaying telescopes. The magneto-rheological technique allows for faster and more accurate finishing of aspheres. The spherical and aspherical lenses were final figured using both conventional-pitch polishing processes for high quality laser optics and the magneto-rheological finishing process. The purpose of this paper is to compare the surface properties between these two finishing processes. Some lenses were set aside from production for evaluation. The surface roughness in the mid-frequency range was measured and the scatter was studied. Laser damage testing at 1064 nm (3-ns pulse width) was performed on surfaces in both the uncoated and coated condition.

    In this paper the replication qualities of periodically and randomly arranged micro-features molded in the injection molding process and their effects on surface properties are studied. The features are molded in PC, PMMA and PP at different mold wall temperatures in order to point out the necessity and profitability of a variotherm mold wall temperature control system. A one-dimensional heat conduction model is proposed to predict the cycle times of the variotherm injection molding processes. With regard to these processes, the molding results are compared to the molded surface feature heights using an atomic force microscope. In addition, the effects of the molded surface features on macroscopic surfaces are characterized in terms of light reflection using a spectrometer and in terms of water wettability by measuring the static contact angle. Furthermore, due to the sensitivity of the surface features on the molded parts, their durability is compared in a scratch test with a diamond tip. This leads to successful implementation in applications in which the optical appearance, in terms of gloss and reflection, and the water repellence, in terms of drag flow and adhesion, are of importance.

    Plasma oxytocin (OT) and arginine vasopressin (AVP) are associated with individual differences in emotional responses and behaviors. The amygdala is considered to be an important brain region for regulating emotion-based behavior, with OT and AVP modulating activity in the amygdala during the processing of negative emotions. In particular, increased OT levels may diminish amygdala activation (anxiolytic effects) and enhanced AVP levels may augment amygdala activation (anxiogenic effects) when negative emotions are processed. A growing body of research has shown that the effects of OT and AVP are modulated by sex: the aforementioned anxiolytic effects of OT and the anxiogenic effects of AVP occur in men, but not in women. However, we have little knowledge regarding the biological mechanisms underlying OT and AVP plasma levels or their respective anxiogenic and anxiolytic effects; similarly, little is known about the causes and nature of sex differences related to these neuropeptides and their effects on emotional processing. In the current study, we focused on the neural functions associated with the biological mechanisms underlying such effects. We hypothesized that amygdala activation would correlate with trait plasma OT (anxiolytic effects) and AVP (anxiogenic effects) levels because the amygdala is thought to affect the coordinated release of these neuropeptides following affective experiences. We further hypothesized that the effects would be modulated by sex. We assessed 51 participants (male and female) using a paradigm involving negative emotion in conjunction with functional magnetic resonance imaging and measurements of plasma OT and AVP levels. We determined that increased plasma AVP levels were positively associated with amygdala activation (anxiogenic effects) in men, but not in women. These findings highlight the potential underlying neural mechanisms of plasma AVP levels in men.

    Full Text Available This article argues that current manifestations of criminalization of protest in contexts rich in natural resources can be inscribed in a wider economic context that contributes to the neutralization of political claims to land, natural resources and self-determination. The first part suggests a view of the tendency to criminalize protests as underpinned by a biopolitical immunization of economic decisions from political contestation. By effecting a normative, impassable disjuncture between what is considered juridical-political and what is considered economic, a biopolitical articulation appears in order to functionally present economic decisions as technical and necessary, and consequently, non-political. The second part of the article presents a preliminary approach to the current configuration of criminalization of protests in Colombia. I argue that recent initiatives to criminalize protests exemplify the manner in which physical violence, whether realized or implied, is playing an important role in the legitimization, foundation, and operation of a new property regime characterized by a de facto land reform, a selective enforcement of property rights and an increasing shielding of economic decisions - concerning natural resources exploitation - from political debate. Este artículo sostiene que las actuales formas de criminalización de la protesta social en contextos de riqueza en recursos naturales, pueden estar inscritas dentro de un contexto más amplio, que contribuye a la neutralización de las luchas en torno a la tierra, los recursos naturales y la autodeterminación. La primera parte presenta una perspectiva de la tendencia a la criminalización de la protesta, justificada como un medio eficiente de inmunización biopolítica de las decisiones económicas y de la confrontación política. Al producir un desentendimiento entre lo que se considera jurídico-político y lo que se considera económico, aparece una articulación biopol

    What is the relationship between decisional conflict, decisional regret and psychological well-being in women following unsuccessful IVF cycles? The mediating effect of decisional regret on the relationship between decisional conflict and fertility-related quality of life (FRQOL) has been found to be moderated by the availability (versus absence) of frozen embryos after an unsuccessful IVF cycle. Infertility treatment is marked by its open-ended nature. Stresses in treatment decision-making could be aggravated by a culture which honours families through procreation. While studies have investigated treatment-related decision-making among infertile women, little is known about the mental health consequences of decisional conflict and decisional regret following an unsuccessful IVF cycle. A study was conducted over a 3-month period with infertile women who had recently experienced a failed IVF cycle (T 0 ). Decisional conflict when they decided on terminating or continuing treatment (T 1 ) and decisional regret 3 months later (T 2 ) were measured. Participants reported their levels of depression, anxiety and FRQOL at three time points. A total of 151 participants completed all time points (attrition rate: 39%). The average age of participants was 37.2 years, and they had had 1.1 cycles (range: 0-8) on average at the time of study intake. The duration of the study was 2 years. Participants were infertile women who were not pregnant following an IVF cycle recruited from a university-affiliated assisted reproduction centre. Following the notification of a negative pregnancy result, patients were invited to complete measures of FRQOL, depression and anxiety across three time points and decisional conflict and decisional regret at T 1 and T 2 respectively. Decisional regret partially mediated the effect of decisional conflict on overall and treatment-specific FRQOL (P IVF cycle (P IVF cycle.

    Full Text Available Ante el creciente deterioro ambiental y sus posibles consecuencias en la salud de la población resulta una prioridad indiscutible el diseño e instrumentación de políticas que controlen las actividades económicas bajo el criterio de protección a la salud humana y al ambiente mismo. Es preciso que dichas políticas consideren la factibilidad económica de las alternativas de protección existentes. Sin embargo, por la cantidad de intereses dentro del área ambiental, otros factores como el social y el político deben también ser considerados. La evaluación económica ha sido vista como un promisorio fundamento para la toma de decisiones en esta materia. Los autores analizan la capacidad de esta herramienta para organizar en forma sistemática y comparable los costos y los beneficios de alternativas para la solución de problemas ambientales. Se resumen las principales características de los estudios de costo-beneficio y costo-efectividad, las formas de evaluación económica del ambiente, y las particularidades de esta área para la aplicación de dichas técnicas de análisis. Se señalan los límites encontrados en estas herramientas para cuantificar los costos no monetarios de los riesgos ambientales y de los consecuentes daños a la salud, tales como el dolor, el sufrimiento ó la incapacidad de personas económicamente inactivas, constituyendo estos aspectos el reto metodológico de la evaluación económica en el área. Se reflexiona sobre la importancia de ampliar los insumos informativos para la toma de decisiones en materia de salud ambiental en aspectos como la distribución de los costos y los beneficios entre los distintos grupos sociales. Por último se señala tanto la creciente politización del tema ambiental, como la posibilidad técnica de manipulación de estas herramientas de análisis. Partiendo de estos elementos se señala la necesidad, por parte de los evaluadores, de ser conscientes sobre las implicaciones pol

    Full Text Available We proposed a low-cost and highly reflective liquid organic sheet silver conductor using back contact reflectors in amorphous silicon (a-Si single junction superstrate configuration thin-film solar cells produced using a nonvacuum screen printing process. A comparison of silver conductor samples with vacuum-system-sputtered silver samples indicated that the short-circuit current density (Jsc of sheet silver conductor cells was higher than 1.25 mA/cm2. Using external quantum efficiency measurements, the sheet silver conductor using back contact reflectors in cells was observed to effectively enhance the light-trapping ability in a long wavelength region (between 600 nm and 800 nm. Consequently, we achieved an optimal initial active area efficiency and module conversion efficiency of 9.02% and 6.55%, respectively, for the a-Si solar cells. The results indicated that the highly reflective sheet silver conductor back contact reflector layer prepared using a nonvacuum process is a suitable candidate for high-performance a-Si thin-film solar cells.

    Full Text Available The available data on well-studied areas of the Turan platform (as an example are reviewed and analyzed to reveal the role of con-sedimentation and post-sedimentation tectonic movements in formation of dislocations of the sedimentary cover. At the background of the long-term (tens and hundreds of million years quiet evolution of the territory under study, short-term intervals are distinguished, which duration amounts to the first millions of years (typically manifested in one or two stratigraphic layers; in such time intervals, tectonic movements were dramatically boosted and accompanied by land uplifting, sea regression, erosion of sediments accumulated earlier and manifestation of deformation processes.The paleotectonic reconstructions show that during such ‘revolutionary’ stages, large tectonic elements occurred along with local uplifts that added to their complexity. In the region under study, the Pre-Jurassic, Pre-Cretaceous (Late Okoma, Pre-Danish and the Pre-Middle Miocene gaps in sedimentation are studied in detail. It is shown that only during the above four periods of sedimentation gaps and accompanying erosion-denudation processes, the regional structures gained from 50 to 80% of their current amplitudes at the bottom of the cover, and the Pre-Danish and Pre-Middle Miocene washout periods were most important.Local uplift also developed impulsively and primarily due to the post-sedimentation movements. Cross-sections of anticlines studied in detail (Figures 1 to 3 are discussed as examples that clearly show the increase of erosional shearing of the sediments accumulated earlier towards domes of uplifts without any con-sedimentation decrease of their thicknesses. During these periods of the geologic history, regardless of their short duration, folded dislocation gained up to 65–90% of their current amplitudes. The periods of activation were separated by long relatively quiescent tectonic periods with the gradually slowing down

    It has been suggested that some aspects of mental state understanding recruit a rudimentary, but fast and efficient, processing system, demonstrated by the obligatory slowing down of judgements about what the self can see when this is incongruent with what another can see. We tested the social nature of this system by investigating to what extent these altercentric intrusions are elicited under conditions that differed in their social relevance and, further, how these related to self-reported social perspective taking and empathy. In Experiment 1, adult participants were asked to make "self" or "other" perspective-taking judgements during congruent ("self" and "other" can see the same items) or incongruent conditions ("self" and "other" cannot see the same items) in conditions that were social (i.e., involving a social agent), semisocial (an arrow), or nonsocial (a dual-coloured block). Reaction time indices of altercentric intrusion effects were present across all conditions, but were significantly stronger for the social than for the less social conditions. Self-reported perspective taking and empathy correlated with altercentric intrusion effects in the social condition only. In Experiment 2, the significant correlations for the social condition were replicated, but this time with gaze duration indices of altercentric intrusion effects. Findings are discussed with regard to the degree to which this rudimentary system is socially specialized and how it is linked to more conceptual understanding.

    The phenomena preceding the Coronal Mass Ejections (CMEs) and observed in the radio-frequency band represent a lot of sporadic components of the emission, that cover the wide frequency range. The study of these phenomena composes the new, prevailing for the last ten years direction. This is caused by the fact that solar radioastronomy possesses the developed network of observant tools, by the sensitive methods of observations. It makes possible in a number of cases to obtain information from the layers of solar atmosphere, inaccessible for the studies by other methods of observations. The purpose of this work is analysis of information about the CMEs preceding radio-events and their dynamics in the centimeter and decimeter radio emission in 1998. We use the data of the worldwide network of solar observatories in the radio-frequency band, the data about the CMEs phenomena and the characteristics are taken from Internet: http://sdaw.gsfc.nasa.gov./CME_list}. From great number of the CMEs we select only such, before which there were no more recorded events in the time interval of 8 hours, and before which sporadic radio emission was observed on 2-hours interval. The selection of this interval was caused by available study about the mean lifetime of precursors before CMEs and powerful flares, as a rule, accompanying CMEs, in the optical, X-ray and radio emissions. It constitutes, on the average, about 30 min. The total volume of data composed 68 analyzed events of CMEs in 1998. The analysis of the spectral- temporary characteristics of sporadic radio emission in the dependence on the CMEs parameters is carried out. The nature of processes at the stage of formation and initial propagation of CMEs, such as floating up of new magnetic fluxes, the development of instabilities, the characteristic scales of phenomena, that have an effect upon the observed radio emission is analyzed. The work is carried out with the support of Russian Fund of Basic Research (grant 03

    Full Text Available Este trabajo discute y compara dos lógicas explicativas del comportamiento electoral: el voto por resultados y el voto ideológico. En concreto, el trabajo pone a prueba uno de los principales supuestos de ambas teorías: que las reglas que guían las decisiones de voto de los ciudadanos son las mismas independientemente de su nivel de interés, conocimiento e información sobre los temas políticos. Para ello se analiza material empírico proveniente de encuestas postelectorales en cuatro democracias: España, Portugal, Hungría y Polonia. Los datos pertenecen al segundo módulo del programa de Estudio Comparado de Sistemas Electorales (CSES, 2005, que contiene información sobre el comportamiento electoral y el conocimiento político de los ciudadanos. Los resultados apuntan a que mientras la influencia del conocimiento político en la lógica del voto por resultados es clara y contundente, resulta mucho menos concluyente en el caso del voto ideológico. Todo ello sugiere que el control democrático de los gobiernos a través de la sanción de su rendimiento requiere unos niveles mínimos de conocimiento e información sobre la política por parte de la ciudadanía.

    The current models for inventory management are complementary, but together they offer a large pallet of elements for solving complex problems of companies when wanting to establish the optimum economic order quantity for unfinished products, row of materials, goods etc. The main objective of this paper is to elaborate an automated decisional model for the calculus of the economic order quantity taking into account the price regressive rates for the total order quantity. This model has two main objectives: first, to determine the periodicity when to be done the order n or the quantity order q; second, to determine the levels of stock: lighting control, security stock etc. In this way we can provide the answer to two fundamental questions: How much must be ordered? When to Order? In the current practice, the business relationships with its suppliers are based on regressive rates for price. This means that suppliers may grant discounts, from a certain level of quantities ordered. Thus, the unit price of the products is a variable which depends on the order size. So, the most important element for choosing the optimum for the economic order quantity is the total cost for ordering and this cost depends on the following elements: the medium price per units, the stock cost, the ordering cost etc.

    Full Text Available This retrospective study aimed to evaluate, through an ad hoc 17-item tool, the Pulmonary Rehabilitation Decisional Score (PRDS, the priority access to PR prescription by respiratory specialists. The PRDS, scoring functional, clinical, disability, frailty, and participation parameters from 0 = low priority to 34 = very high priority for PR access, was retrospectively calculated on 124 specialist reports sent to the GP of subjects (aged 71±11 years, FEV1%  51±17 consecutively admitted to our respiratory outpatient clinic. From the specialist’s report the final subject’s allocation could be low priority (LP (>60 days, high priority (HP (30–60 days, or very high priority (VHP (<30 days to rehabilitation. The PRDS calculation showed scores significantly higher in VHP versus LP (p<0.001 and significantly different between HP and VHP (p<0.001. Comparing the specialist’s allocation decision and priority choice based on PRDS cut-offs, PR prescription was significantly more appropriate in VHP than in HP (p=0.016. Specialists underprescribed PR in 49% of LP cases and overprescribed it in 46% and 30% of the HP and VHP prescriptions, respectively. A multicomprehensive score is feasible being useful for staging the clinical priorities for PR prescription and facilitating sustainability of the health system.

    Full Text Available Se analiza la importancia de los informes psicológicos forenses en la toma de decisiones judiciales de primera instancia en delitos sexuales en la ciudad de Barranquilla (Colombia mediante un enfoque cuantitativo de alcance descriptivo. Se analizaron diversas variables con el propósito de categorizar si en las sentencias judiciales se menciona la pericial por el juez al momento de dictarlas, y cuál es el valor diferencial de los informes psicológicos forenses. También se revisó la concordancia entre la decisión final del juez y los resultados plasmados en el informe psicológico. Como conclusión significativa se obtuvo que en el 80 % de las sentencias hubo mención a la pericial por el juez al fundamentar su decisión; en un 80 % de los casos el juez tomó la decisión de manera concordante con los resultados del informe psicológico. Como conclusión se plantea que para la Administración de Justicia se requiere personal auxiliar especializado y que el psicólogo jurídico en función forense funge como fuente directa de conocimiento, y se constituye en un medio de convicción apreciable.

El desempeño en la TD se evaluó con la tarea de Game Dice Task (GDT –Tarea del Juego de los Dados de Brand–. También se aplicaron otras pruebas y tareas de evaluación cognitiva para determinar la relación de la TD con otras Funciones Ejecutivas (FE. Los resultados permitieron establecer que el proceso de TD se deteriora desde los comienzos de la enfermedad, evidenciando que el desempeño de los sujetos con EA es significativamente inferior al de los sujetos sanos, con un porcentaje mayor de respuestas de riesgo y aumentos significativos de los tiempos de respuesta. También se observó deterioro en todas las funciones ejecutivas evaluadas. El trabajo provee evidencia empírica que soporta la idea de que la TD se encuentra estrechamente relacionada a las demás FE.

Su especial entramado de conexiones con otras áreas de la corteza y con estructuras subcorticales como la amígdala justifican que pueda tener un papel de interfase entre cognición y emoción, y desempeñar una función fundamental en la regulación y el control del comportamiento. En este trabajo revisamos estudios realizados con la tarea de apuestas de Iowa, tareas de aprendizaje de inversión afectivo, tareas de apuestas con diferente varianza para medir la propensión al riesgo y tareas que introducen demora temporal de la recompensa para evaluar la impulsividad. Los datos obtenidos en esos trabajos con pacientes lesionados en la VMPFC o en otras áreas prefrontales y controles no lesionados, y datos conductuales y de actividad cerebral pueden interpretarse mejor si asumimos que la VMPFC está encargada de representar la expectativa de refuerzo. La representación de un reforzador esperado incluye la demora del reforzador, y la varianza de su magnitud.

    Shared decision making is increasingly recognized as the ideal model of patient-physician communication especially in chronic diseases with partially effective treatments as multiple sclerosis (MS). To evaluate prerequisite factors for this kind of decision making we studied patients' decisional role preferences in medical decision making, knowledge on risks, information interests and the relations between these factors in MS. After conducting focus groups to generate hypotheses, 219 randomly selected patients from the MS Outpatient Clinic register (n = 1374) of the University Hospital Hamburg received mailed questionnaires on their knowledge of risks in MS, their perception of their own level of knowledge, information interests and role preferences. Most patients (79%) indicated that they preferred an active role in treatment decisions giving the shared decision and the informed choice model the highest priority. MS risk knowledge was low but questionnaire results depended on disease course, disease duration and ongoing immune therapy. Measured knowledge as well as perceived knowledge was only weakly correlated with preferences of active roles. Major information interests were related to symptom alleviation, diagnostic procedures and prognosis. Patients with MS claimed autonomous roles in their health care decisions. The weak correlation between knowledge and preferences for active roles implicates that other factors largely influence role preferences.

    Full Text Available Procrastination as putting off until tomorrow what one had intended to do today is well-known tendency in everyday life. In an attempt to understand the character of procrastination in different life-domains, a large body of research has been accumulated over the last decades. This article was aimed to evaluate a specific decisional procrastination of school-to-work transition (SWT that is treated as maturity postponement. Two studies are reported examining SWT procrastination defined as career indecision among Polish students graduating universities. In Study 1 (N=366, attitudinal and identity statuses were analyzed as correlates of career procrastination. A path analysis conducted for the model, which was aimed to explain the influence of career self-efficacy and occupational commitment on career indecision (dependent variable, revealed its very good fitness (RMSEA=.000. Those two independent variables explain 10% of career indecision variance. Stepwise multiple regression analyses conducted to ascertain relationship of five identity statuses (Brzezińska, Piotrowski, 2010 to procrastination measure (career indecision showed that Commitment Making and Ruminative Exploration are strongest predictor variables. In study 2 (N=157, the stepwise multiple regression analyses conducted to ascertain the independent relationship of each of Big Five personality factor revealed that Neuroticism and Extraversion accounts of the most of explained variance of school-to-work transition procrastination.

    Full Text Available Los individuos adolescentes aprenden de sexualidad a través de diferentes medios, pero la familia es uno de los primeros agentes socializadores y es la encargada, a través de la comunicación, de trasmitir información sobre ésta. Este estudio tiene como objetivo describir los procesos de comunicación que se establecen entre padres y madres con sus hijos e hijas adolescentes para entablar diálogos sobre sexualidad y su relación con la toma de decisiones, en dos familias pertenecientes a instituciones educativas de Cali. A través de esta investigación cualitativa encontramos que los procesos de comunicación, los temas abordados y los recursos empleados, están influidos por los conocimientos y percepciones de los ascendientes, en quienes la sexualidad aún es un tabú y tienen carencia de información y de estrategias de acompañamiento.

    Full Text Available This research was carried out with the aim to analyze the methodological strategy adopted by the coach of the Brazilian youth man volleyball team during training sessions in the preparation period. As a data gathering method, 45 videos were taken during sessions, 28 in Belo Horizonte and 17 in Poços de Caldas. A semi-structured interview was also held with the coach and the coaching staff . The results of the research indicated that the coach’s pedagogical practice was strongly influenced by technical, developmental and systemic methodological conceptions. This practice was developed through a combination of different methodologies, such as analytic, synthetic, structuralist, dynamic and progressive. The relationship between the coaching staff and the athletes was harmonious and respectful. It was shown that, besides to anthropometric, conditioning, technical-coordinating, tactical-cognitive and psychological factors, the twelve athletes who represented Brazil in the World Youth Championshipwere also chosen for other qualities. Among the qualities to be mentioned are the capacity for leadership, group cohesion, courage and determination . The research pointed out that the preparation process of the Brazilian team was carried out with great competence, through a correct division of training time and a careful selection of the athletes, following international standard criteria such as height, strength and individual technical skills.

    Full Text Available Resumen En la actualidad existe una inmensa variedad de técnicas ortodóncicas, cada una de ellas con sus indicaciones y usos específicos a partir de las cuales se debe seleccionar la más apropiada para cada situación clínica. El objetivo de este artículo es revisar en la literatura reciente los factores que influyen o que explicarían las decisiones terapéuticas que se toman en odontología, centrados en la especialidad de ortodoncia. Se ha pesquisado que la educación recibida, las preferencias individuales y el dominio de las diferentes técnicas, las características y valores personales, la situación clínica y económica del paciente, el sistema de salud y la relación odontólogo-paciente adquieren un papel importante en la selección del tratamiento. También cobran importancia los principios éticos y aspectos sociales, tales como las teorías del comportamiento que son homologables al actuar profesional. Es importante comprender la toma de decisiones y la selección de los tratamientos por el impacto que tiene en la atención del paciente y su satisfacción, en el cumplimiento de los objetivos terapéuticos, el funcionamiento de la salud pública y la calidad de los servicios entregados. En la actualidad son escasos los estudios dedicados al proceso de toma de decisiones clínicas, por lo que se hace necesario ampliar los alcances de las investigaciones, incluyendo investigaciones cualitativas, con el fin de comprender más profundamente el fenómeno de la toma de decisiones.

    1984-01-01

    A classical description of the one dimensional radiative transfer treatment of vegetation canopies was completed and the results were tested against measured prairie (blue grama) and agricultural canopies (soybean). Phase functions are calculated in terms of directly measurable biophysical characteristics of the canopy medium. While the phase functions tend to exhibit backscattering anisotropy, their exact behavior is somewhat more complex and wavelength dependent. A Monte Carlo model was developed that treats soil surfaces with large periodic variations in three dimensions. A photon-ray tracing technology is used. Currently, the rough soil surface is described by analytic functions and appropriate geometric calculations performed. A bidirectional reflectance distribution function is calculated and, hence, available for other atmospheric or canopy reflectance models as a lower boundary condition. This technique is used together with an adding model to calculate several cases where Lambertian leaves possessing anisotropic leaf angle distributions yield non-Lambertian reflectance; similar behavior is exhibited for simulated soil surfaces.

    Women with early-stage breast cancer, of whom only 15% will experience a recurrence, are often conflicted or uncertain about taking chemotherapy. Gene expression profiling (GEP) of tumours informs risk prediction, potentially affecting treatment decisions. We examined whether receiving a GEP test score reduces decisional conflict in chemotherapy treatment decision making. A general population sample of 200 women completed the decisional conflict scale (DCS) at baseline (no GEP test score scenario) and after (scenario with GEP test score added) completing a discrete choice experiment survey for early-stage breast cancer chemotherapy. We scaled the 16-item DCS total scores and subscores from 0 to 100 and calculated means, standard deviations and change in scores, with significance (p change their chemotherapy decision after receiving GEP testing information. Total score and all subscores (uncertainty, informed, values clarity, support, and effective decision) decreased significantly in the respondent subgroup who were unsure about taking chemotherapy initially but changed to no chemotherapy (n =33). In the subgroup of respondents (n = 25) who chose chemotherapy initially but changed to unsure, effective decision subscore increased significantly. In the overall sample, changes in total and all subscores were non-significant. GEP testing adds value for women initially unsure about chemotherapy treatment with a decrease in decisional conflict. However, for women who are confident about their treatment decisions, GEP testing may not add value. Decisions to request GEP testing should be personalised based on patient preferences.

    2014-04-01

    We offer a minor technical correction to the published proof of part (ii) of the main theorem in Silbert and Thomas (Psychonomic Bulletin & Review, 20, 1-20, 2013) that somewhat limits the scope of the equivalence observed in that work. Specifically, in order for a mean shift integrality with decisional separability to be mimicked by a perceptually separable but nondecisionally separable configuration, one needs to assume stimulus invariance. This holds when all of the covariance matrices in the stimulus configuration are equal to each other. We note that part (i) of the theorem is unaffected by this modification; an empirical finding of perceptual separability and the failure of decisional separability can be mimicked by a perceptually nonseparable, decisionally separable configuration without restricting the covariance matrices to be equal. We also note that stimulus invariance is often assumed in simple designs (e.g., Macmillan & Ornstein in Journal of the Acoustical Society of America, 97, 1261-1285, 1998), due to the implausibility of different perceptual correlations being present within stimuli perched very closely in perceptual space.

    Full Text Available En esta época de respeto por la ciencia médica y por la responsabilidad gerencial, las organizaciones de salud deben rendir cuentas por sus acciones con creciente frecuencia. La época en que se determinaban las prioridades y se tomaban las decisiones sobre bases políticas o acatando el consejo intuitivo de asesores respetados y bien intencionados ha dado paso gradualmente a una era que valora la demostración de efectividad y eficiencia. Las decisiones relativas a las prioridades y a los programas deben basarse firmemente en conocimientos comprobados y someterse a evaluación continua. Esta transición requiere promover el pensamiento crítico en todos los ámbitos. Surge entonces la siguiente pregunta: ¿Cómo podemos promover el razonamiento crítico en los servicios de salud para fijar prioridades, adoptar decisiones acertadas y poner en práctica iniciativas efectivas? En otras palabras, ¿cómo podemos pasar de la evidencia al desempeño? Una pregunta aún más básica es ¿por qué debemos fijar prioridades?

    Reflection is a fuzzy concept. In this article we reveal the paradoxes involved in studying the nature of reflection. Whereas some scholars emphasize its discursive nature, we go further and underline its resemblance to the self-biased dialogue Socrates had with the slave in Plato's Meno . The individual and internal nature of the reflection process creates difficulty for studying it validly and reliably. We focus on methodological issues and use Hans Linschoten's view of coupled systems to identify, analyze, and interpret empirical research on reflection. We argue that researchers and research participants can take on roles in several possible system couplings. Depending on who controls the manipulation of the stimulus, who controls the measuring instrument, who interprets the measurement and the response, different types of research questions can be answered. We conclude that reflection may be validly studied by combining different couplings of experimenter, manipulation, stimulus, participant, measurement, and response.

    To investigate high-risk breast cancer survivors' risk reduction decision making and decisional conflict after an uninformative BRCA1/2 test. Prospective, longitudinal study of 182 probands undergoing BRCA1/2 testing, with assessments 1-, 6-, and 12-months postdisclosure. Primary predictors were health beliefs and emotional responses to testing assessed 1-month postdisclosure. Main outcomes included women's perception of whether they had made a final risk management decision (decision status) and decisional conflict related to this issue. There were four patterns of decision making, depending on how long it took women to make a final decision and the stability of their decision status across assessments. Late decision makers and nondecision makers reported the highest decisional conflict; however, substantial numbers of women--even early and intermediate decision makers--reported elevated decisional conflict. Analyses predicting decisional conflict 1- and 12-months postdisclosure found that, after accounting for control variables and decision status, health beliefs and emotional factors predicted decisional conflict at different timepoints, with health beliefs more important 1 month after test disclosure and emotional factors more important 1 year later. Many of these women may benefit from decision making assistance. Copyright 2009 APA, all rights reserved.

Ultimately, the objection is that his reductivist view is unequipped to address the rclassical problems of rational deliberation and agential authority.

    Full Text Available The article presents the research results of the DECIMAL European project. The aim of the project is to produce an integrated decision support module for library management systems used in small and medium size libraries. The quantitative and qualitative research carried out in United Kingdom, Italy and Spain has been based on a combination of different methods: literature review, interviews, questionnaires and discussion groups during both presentation workshops held. Two basic research lines are discerned: the first one involving the real use of performance measures and indicators in management and evaluation of the library activities, and also their potential interest in the case they have not been applied to the present, and the second one involving the type of decisions most frequantly made in libraries and the issues that influence decision-making process (information sources used, organizational culture, training, satisfaction level.
    The article has been centered in the results obtained in Spanish libraries, but the general results are also mentioned in order to be compared. The conclusions of the study have resulted in the user requirement specification, as a first step in the design of the decision support module. The project has concluded with a prototype evaluation phase organised as an iterative testing of the prototypes and successive software modifications. The development of four versions of the module has resolved the problems identified earlier in the evaluation process.

    The aim of the present study was to evaluate the effects of gastric pH on the oral absorption of poorly water-soluble drugs using an in vitro system. A dissolution/permeation system (D/P system) equipped with a Caco-2 cell monolayer was used as the in vitro system to evaluate oral drug absorption, while a small vessel filled with simulated gastric fluid (SGF) was used to reflect the gastric dissolution phase. After applying drugs in their solid forms to SGF, SGF solution containing a 1/100 clinical dose of each drug was mixed with the apical solution of the D/P system, which was changed to fasted state-simulated intestinal fluid. Dissolved and permeated amounts on applied amount of drugs were then monitored for 2h. Similar experiments were performed using the same drugs, but without the gastric phase. Oral absorption with or without the gastric phase was predicted in humans based on the amount of the drug that permeated in the D/P system, assuming that the system without the gastric phase reflected human absorption with an elevated gastric pH. The dissolved amounts of basic drugs with poor water solubility, namely albendazole, dipyridamole, and ketoconazole, in the apical solution and their permeation across a Caco-2 cell monolayer were significantly enhanced when the gastric dissolution process was reflected due to the physicochemical properties of basic drugs. These amounts resulted in the prediction of higher oral absorption with normal gastric pH than with high gastric pH. On the other hand, when diclofenac sodium, the salt form of an acidic drug, was applied to the D/P system with the gastric phase, its dissolved and permeated amounts were significantly lower than those without the gastric phase. However, the oral absorption of diclofenac was predicted to be complete (96-98%) irrespective of gastric pH because the permeated amounts of diclofenac under both conditions were sufficiently high to achieve complete absorption. These estimations of the effects of

    A 3 kW single stage all-fiber Yb-doped single-mode fiber laser with bi-directional pumping configuration has been demonstrated. Our newly developed high-power LD modules are employed for a high available pump power of 4.9 kW. The length of the delivery fiber is 20 m which is long enough to be used in most of laser processing machines. An output power of 3 kW was achieved at a pump power of 4.23 kW. The slope efficiency was 70%. SRS was able to be suppressed at the same output power by increasing ratio of backward pump power. The SRS level was improved by 5dB when 57% backward pump ratio was adopted compared with the case of 50%. SRS was 35dB below the laser power at the output power of 3 kW even with a 20-m delivery fiber. The M-squared factor was 1.3. Single-mode beam quality was obtained. To evaluate practical utility of the 3 kW single-mode fiber laser, a Bead-on-Plate (BoP) test onto a pure copper plate was executed. The BoP test onto a copper plate was made without stopping or damaging the laser system. That indicates our high power single-mode fiber lasers can be used practically in processing of materials with high reflectivity and high thermal conductivity.

    The aluminized polymer film used in spacecraft as a radiation barrier to protect both astronauts and delicate instruments has led to a number of spinoff applications. Among them are aluminized shipping bags, food cart covers and medical bags. Radiant Technologies purchases component materials and assembles a barrier made of layers of aluminized foil. The packaging reflects outside heat away from the product inside the container. The company is developing new aluminized lines, express mailers, large shipping bags, gel packs and insulated panels for the building industry.

A pesar de las ventajas que ha propiciado el uso de estos sistemas y de las dificultades detectadas con el tratamiento y la forma en que se utilizan los datos para dar soporte a las decisiones en el ámbito académico universitario, no se ha evidenciado un uso sistemático de los mismos. Debido al aumento del volumen de los datos almacenados, los profesores y directivos se enfrentan a un ambiente de incertidumbre y complejidad crecientes. Generalmente no se cuenta con las herramientas necesarias para manipular estos datos y convertirlos en información valiosa.

    Full Text Available The specular neutron reflectivity is a technique enabling the measurement of neutron scattering length density profile perpendicular to the plane of a surface or an interface, and thereby the profile of chemical composition. The characteristic sizes that are probed range from around 5 Å up 5000 Å. It is a scattering technique that averages information on the entire surface and it is therefore not possible to obtain information within the plane of the interface. The specific properties of neutrons (possibility of tuning the contrast by isotopic substitution, sensitivity to magnetism, negligible absorption, low energy of the incident neutrons makes it particularly interesting in the fields of soft matter, biophysics and magnetic thin films. This course is a basic introduction to the technique and does not address the magnetic reflectivity. It is composed of three parts describing respectively its principle and its formalism, the experimental aspects of the method (spectrometers, samples and two examples related to the materials for energy.

    Full Text Available This study aimed to 1 examine relationships between uncertainty, perceived information, personal values, social support, and filial obligation among Chinese family caregivers faced with nursing home placement of an older adult family member with dementia; and 2 describe the applicability of the Decisional Conflict Scale in nursing home placement decision making among Chinese family caregivers through the integration of quantitative and qualitative data. We used a mixed-methods approach. Quantitative data analysis consisted of descriptive and correlational statistics. We utilized a thematic analysis for the qualitative data. Data transformation and data comparison techniques were used to combine qualitative and quantitative data. Thirty Chinese family caregivers living in Taiwan caring for an older adult with dementia participated in this study. We found a significant association among the quantitative findings, which indicated that perceived information, personal values, social support, and filial obligation, and nursing home placement decisional conflict. Mixed-method data analysis additionally revealed that conflicting differences existed between the traditional role of Chinese family collective decision making and the contemporary role of single family member surrogate decision making. Although the Decisional Conflict Scale can be utilized when exploring nursing home placement for an older adult with dementia among Chinese family caregivers, applicability issues existed regarding cultural beliefs and values related to filial piety and family collectivism. Findings strongly support the need for researchers to consider cultural beliefs and values when selecting tools that assess health-related decision making across cultures. Further research is needed to explore the role culture plays in nursing home decision making.

    Life science has a need for detection methods that are label-free and real-time. In this paper, we have selected staphylococcal protein A (SPA) and swine immunoglobulin G (IgG), and monitor the bindings between SPA and swine IgG with different concentrations, as well as the dissociations of SPA-swine IgG complex in different pH values of phosphate buffer by oblique-incidence reflectivity difference (OIRD) in a label-free and real-time fashion. We obtain the ON and OFF reaction dynamic curves corresponding to the bindings and dissociations of SPA and swine IgG. Through our analysis of the experimental results, we have been able to obtain the damping coefficients and the dissociation time of SPA and swine IgG for different pH values of the phosphate buffer. The results prove that the OIRD technique is a competing method for monitoring the dynamic processes of biomolecule interaction and achieving the quantitative information of reaction kinetics.

    In casual conversations, words often lack segments. This study investigates whether listeners rely on their experience with reduced word pronunciation variants during the processing of single segment reduction. We tested three groups of listeners in a lexical decision experiment with French words produced either with or without word-medial schwa (e.g., /ʀvy/ and /ʀvy/ for revue). Participants also rated the relative frequencies of the two pronunciation variants of the words. If the recognition accuracy and reaction times (RTs) for a given listener group correlate best with the frequencies of occurrence holding for that given listener group, recognition is influenced by listeners' exposure to these variants. Native listeners' relative frequency ratings correlated well with their accuracy scores and RTs. Dutch advanced learners' accuracy scores and RTs were best predicted by their own ratings. In contrast, the accuracy and RTs from Dutch beginner learners of French could not be predicted by any relative frequency rating; the rating task was probably too difficult for them. The participant groups showed behaviour reflecting their difference in experience with the pronunciation variants. Our results strongly suggest that listeners store the frequencies of occurrence of pronunciation variants, and consequently the variants themselves.

  20. Increasing awareness about self and facilitation practice in preparation for transitioning to a new role – the critical reflective process of becoming a certified professional facilitator

    2015-11-01

    Full Text Available Background and context: I have been working as a practice developer in the Australian healthcare system for more than 10 years. For the last seven of those I was a lead facilitator for a practice development programme that is being implemented across a large statewide health service. The programme’s purpose is to create person-centred care environments that enable patient and staff empowerment. My role was in a small team that supported facilitators predominantly at local health district and state levels. The intent was to phase out the team over time as capacity increased and local teams gained the required skills and knowledge to continue implementing the programme. During the two-year final transition phase, a strategic plan was implemented to guide the development of systems and capacity that would support the programme once the team had exited. A decision was made to shorten the phasing-out period and during this transition period I found myself facing an unknown and unpredictable future, for the first time in my career promoting something other than my clinical nursing skills. As I transitioned into an independent facilitator role I wanted to consolidate my expertise as a facilitator, to gain further learning in specific areas and to achieve recognition of the facilitation skill set I had honed over time, and which has now become my way of working. Given that my experience was limited to the healthcare context, diverse though it is, I pondered which of my skills would stand me in good stead to enable groups and organisations as an independent professional facilitator and what additional skills I’d need. I was encouraged to become a certified professional facilitator by colleagues who were using process facilitation and person-centredness more broadly. This paper reflects my experience of the preparation, assessment and accreditation process, the feedback I received from my international assessors and how these are influencing my

    The aim of this study was to clarify the relationship between social support, decisional conflict, and attitude towards advance directives, and determine whether decisional conflict mediates the relation between social support and advance directives attitude among older adults in South Korea. In total, 209 community-based older adults (mean age, 74.82 years) participated in this cross-sectional study. Demographic characteristics, self-perceived health status, social support, decisional conflict, and advance directives attitude were investigated via a structured questionnaire. Data analysis was carried out using Pearson's correlation and path analyses. The mean score of advance directives attitude was 48.01 (range, 35-61). Decisional conflict and social support were both significantly related to advance directives attitude (P conflict was a mediator between social support and advance directives attitudes. The results confirmed the importance of social support for reducing decisional conflict and encouraging positive attitudes toward advance directives. Future studies are needed to support the development of culturally sensitive educational approaches regarding advance directives for older adults in Korea. © 2015 The Authors.

    Children with life-threatening illnesses and their families may face a myriad of medical decisions in their lifetimes. Oftentimes these complicated medical decisions cause disagreements among patients, families, and providers about what is the best course of action. Although no evidence exists, it is possible that conflict may affect subgroups of the population differently. This study aims to investigate how decisional conflict varies among racial and ethnic subgroups. Two hundred sixty-six surveys were completed with parents whose children have a life-threatening illness. All children lived in Florida and were enrolled in the Medicaid program. The Decisional Conflict Scale, overall and broken down into its five distinct subscales, was used to assess parental decision-making. Descriptive, bivariate, and multivariate analyses were conducted. Subgroup analyses were conducted on Latino respondents. Our bivariate results suggest that minority parents report less Effective Decision Making (pracial and ethnic differences in decisional conflict of parents of children with life-threatening illnesses. Significant differences exist by race, ethnicity, language spoken, and diagnosis time across several subdomains of decisional conflict. These differences are important to address when creating clinical care plans, engaging in shared decision-making, and creating interventions to alleviate decisional conflict.

    Full Text Available There has been some acknowledgement in the published literature that reflection is a crucial element of the evidence based library and information practice (EBLIP model we have adopted (Booth 2004, 2006; Grant 2007; Helliwell 2007. As we work through a problem and try to incorporate the best available evidence into our decision making, reflection is required at several stages, including the very identification of the problem through to our assessment of the process itself and what we have learned in order to inform future practice. However, reflection and reflective writing have not fully been integrated into the process we espouse, and very little has been done to look more closely at this element of the model and how it can be integrated into professional learning.In a recently published research article, Sen (2010 confirms the relationship between reflection and several aspects of professional practice. These include critical review and decision making, two aspects that are tied closely to the evidence based process. Sen notes: Students were more likely to show evidence of learning, self‐development, the ability to review issues crucially, awareness of their own mental functions, ability to make decision [sic] and being empowered when they had mastered the art of reflective practice and the more deeply analytical reflective writing. (p.84 EBLIP (the journal tries to incorporate elements of reflection within the articles we publish. While we clearly believe in the need for our profession to do quality research and publish that research so that it can be accessible to practitioners, we also know that research cannot be looked at in isolation. Our evidence summaries are one way of reflecting critically on previously published research, and in the same vein, our classics bring older research studies back to the foreground. This work needs to continue to be discussed and looked at for its impact on our profession.More directly, the Using

    Cancer patients rely on multiple sources of support when making treatment decisions; however, most research studies examine the influence of health care provider support while the influence of family member support is understudied. The current study fills this gap by examining the influence of health care providers and partners on decision-making satisfaction. In a cross-sectional study via an online Qualtrics panel, we surveyed cancer patients who reported that they had a spouse or romantic partner when making cancer treatment decisions (n = 479). Decisional support was measured using 5-point, single-item scales for emotional support, informational support, informational-advice support, and appraisal support. Decision-making satisfaction was measured using Holmes-Rovner and colleagues' (1996) Satisfaction With Decision Scale. We conducted a mediated regression analysis to examine treatment decision-making satisfaction for all participants and a moderated mediation analysis to examine treatment satisfaction among those patients offered a clinical trial. Results indicated that partner support significantly and partially mediated the relationship between health care provider support and patients' decision-making satisfaction but that results did not vary by enrollment in a clinical trial. This study shows how and why decisional support from partners affects communication between health care providers and cancer patients.

    To assess knowledge, satisfaction with information, decisional conflict and psychological morbidity amongst women diagnosed with ductal carcinoma in situ (DCIS) and to explore the factors associated with less knowledge and greater confusion about DCIS. A cross-sectional survey of women diagnosed with DCIS in Australia (N=144). This study found misunderstanding and confusion amongst women diagnosed with DCIS and a desire for more information about their breast disease. Approximately half of participants worried about their breast disease metastasizing; approximately half expressed high decisional conflict; 12% were anxious and 2% were depressed. Logistic regression analysis demonstrated that worry about dying from the breast disease was significantly associated with not knowing that DCIS could not metastasize (OR 3.9; 95% CI 1.03-14.25); and confusion about whether DCIS could metastasize was significantly associated with dissatisfaction with information (OR 12.5; 95% CI 3.8-40.2). Good communication about how DCIS differs from invasive breast cancer is essential to alleviating the confusion and worry amongst women with DCIS. Recommendations about how best to communicate a diagnosis of DCIS, including the uncertainties, are needed to guide health professionals to promote better understanding about DCIS and increase the well-being of women with DCIS.

    Manufacturing the solid dosage form of an orally administered drug requires lubrication to enhance manufacturability, ensuring that critical quality attributes such as disintegration and dissolution of the drug product are maintained during manufacture. Here, to evaluate lubrication performance during manufacture, we used terahertz attenuated total reflection (THz-ATR) spectroscopy to detect differences in the physical characteristics of the lubricated powder. We applied a simple formulation prepared by blending granulated lactose as filler with magnesium stearate as lubricant. A flat tablet was prepared using the lubricated powder to acquire sharp THz-ATR absorption peaks of the samples. First, we investigated the effects of lubricant concentration and compression pressure on preparation of the tablet and then determined the effect of the pressure applied to samples in contact with the ATR prism on sample absorption amplitude. We focused on the differences in the magnitudes of spectra at the lactose-specific frequency. Second, we conducted the dynamic lubrication process using a 120-L mixer to investigate differences in the magnitudes of absorption corresponding to the lactose-specific frequency during lubrication. In both studies, enriching the lubricated powder with a higher concentration of magnesium stearate or prolonging blending time correlated with higher magnitudes of spectra at the lactose-specific frequency. Further, in the dynamic lubrication study, the wettability and disintegration time of the tablets were compared with the absorption spectra amplitudes at the lactose-specific frequency. We conclude that THz-ATR spectroscopy is useful for detecting differences in densities caused by a change in the physical properties of lactose during lubrication.

    Segmenting objects of interest from 3D datasets is a common problem encountered in biological data. Small field of view and intrinsic biological variability combined with optically subtle changes of intensity, resolution and low contrast in images make the task of segmentation difficult, especially for microscopy of unstained living or freshly excised thick tissues. Incorporating shape information in addition to the appearance of the object of interest can often help improve segmentation performance. However, shapes of objects in tissue can be highly variable and design of a flexible shape model that encompasses these variations is challenging. To address such complex segmentation problems, we propose a unified probabilistic framework that can incorporate the uncertainty associated with complex shapes, variable appearance and unknown locations. The driving application which inspired the development of this framework is a biologically important segmentation problem: the task of automatically detecting and segmenting the dermal-epidermal junction (DEJ) in 3D reflectance confocal microscopy (RCM) images of human skin. RCM imaging allows noninvasive observation of cellular, nuclear and morphological detail. The DEJ is an important morphological feature as it is where disorder, disease and cancer usually start. Detecting the DEJ is challenging because it is a 2D surface in a 3D volume which has strong but highly variable number of irregularly spaced and variably shaped “peaks and valleys”. In addition, RCM imaging resolution, contrast and intensity vary with depth. Thus a prior model needs to incorporate the intrinsic structure while allowing variability in essentially all its parameters. We propose a model which can incorporate objects of interest with complex shapes and variable appearance in an unsupervised setting by utilizing domain knowledge to build appropriate priors of the model. Our novel strategy to model this structure combines a spatial Poisson process

    Full Text Available This paper presents a methodology to analyze decisions in the design of concrete structures. Specifically, we propose a multi-criteria approach to assess the value implications of precast concrete technologies versus in-situ concrete solutions. First, we emphasize the importance of careful decision-making in early stages of construction projects to enhance customer value. Second, we present a decisionmaking methodology that uses fuzzy logic to represent and synthesize information about risk-return tradeoffs in the different kinds of variables involved in the evaluation of a project’s value. To illustrate, we use our methodology to analyze precast vs. in-situ solutions in the design of drainage structures. The results of our analysis point at precast solutions as the most desirable design choice in this setting, and highlight the importance of value analysis in early stages of construction projects.

    El presente artículo hace una breve reflexión sobre las alternativas in situ y prefabricadas para estructuras de hormigón, justificando la necesidad de profundizar en métodos multicriterio como ayuda a la toma de decisiones. Manifiesta la trascendencia de la calidad en las decisiones más allá de este ámbito concreto, así como su influencia en la mayor eficiencia de las obras. Presenta luego un sistema de ayuda a la toma de decisiones basado en matemática difusa, que considera el valor de cada alternativa contemplando el riesgo inherente. Para ilustrarlo desarrolla un ejemplo aplicado a pasos inferiores que pueden resolverse mediante prefabricación o in situ. Efectuándolo por completo, llega a dos conclusiones principales: la bondad de la herramienta presentada y cómo la solución prefabricada, en este caso, aporta mayor valor. Concluye también que todo buen gestor debe plantearse su toma de decisión desde los inicios de cualquier proyecto, empleando herramientas como la presentada.

    Full Text Available Este artículo evalúa cuál ha sido el papel de las decisiones de política monetaria del Banco de la República dentro de los procesos de inestabilidad financiera acaecidos en Colombia en el período 1996-2012. Según la revisión de hechos, la crisis de 1999 puso en duda el papel estabilizador del banco central, lo cual reflejó una postura contra-cíclica demasiado débil para la recuperación, y la crisis de 2008 encontró un banco más preparado, aunque con respuesta tardía a los procesos emergentes de fragilidad financiera. A través de estimaciones econométricas se evidencia que una política monetaria contractiva puede inducir una crisis financiera cuando la reacción se da en momentos de mayor estrés financiero. This paper evaluates what has been the role of the monetary policy decisions taken by the Central Bank during the financial instability processes that Colombia has gone through during 1996 – 2012. According to the fact analysis, the 1999 crisis questioned the role of the central bank, which defended a counter-cyclic posture that was not strong enough to lead the economic recovery. The 2008 crisis found a stronger stand­ing Central Bank, even though it answered late to the emerging processes regarding financial fragility. With the use of econometric studies it was proven that a contractive monetary policy can accelerate a financial crisis when the measure is implemented in moments when the financial stress is too high.

    This paper describes the design and construction of a compact, "user-friendly" polarization-modulation infrared reflection absorption spectroscopy (PM-IRRAS) instrument at the Center for Functional Nanomaterials (CFN) of Brookhaven National Laboratory, which allows studying surfaces at pressures ranging from ultra-high vacuum to 100 Torr. Surface infrared spectroscopy is ideally suited for studying these processes as the vibrational frequencies of the IR chromophores are sensitive to the nature of the bonding environment on the surface. Relying on the surface selection rules, by modulating the polarization of incident light, it is possible to separate the contributions from the isotropic gas or solution phase, from the surface bound species. A spectral frequency range between 1000 cm-1 and 4000 cm-1 can be acquired. While typical spectra with a good signal to noise ratio can be obtained at elevated pressures of gases in ˜2 min at 4 cm-1 resolution, we have also acquired higher resolution spectra at 0.25 cm-1 with longer acquisition times. By way of verification, CO uptake on a heavily oxidized Ru(0001) sample was studied. As part of this test study, the presence of CO adsorbed on Ru bridge sites was confirmed, in agreement with previous ambient pressure X ray photoelectron spectroscopy studies. In terms of instrument performance, it was also determined that the gas phase contribution from CO could be completely removed even up to pressures close to 100 Torr. A second test study demonstrated the use of the technique for studying morphological properties of a spin coated polymer on a conductive surface. Note that this is a novel application of this technique. In this experiment, the polarization of incident light was modulated manually (vs. through a photoelastic modulator). It was demonstrated, in good agreement with the literature, that the polymer chains preferentially lie parallel with the surface. This PM-IRRAS system is small, modular, and easily

    The evolution history of Central Asian Orogen Belt (CAOB) is still the main tectonic problems in northeastern Asia. The Siberia Craton (NC), North China Craton (NCC) and several blocks collided, and the resulting tectonic collage formed as the Paleo-Asian Ocean disappeared. Concerning the northern margin of North China Craton, many different geological questions remain unanswered, such as: the intracontinental orogenic process in the Yanshan orogen and the nature and location of the suture between the southern NC and the northern NCC. In Dec 2009, a 400 km long seismic refraction and wide-angle reflection profile was completed jointly by Institute of Geology, CAGS and University of Oklahoma. The survey line extended from the west end of the Yanshan orogen, across a granitoid belt to the Solonker suture zone. The recording of seismic waves from 8 explosions (500~1500 kg each) was conducted in four deployments of 300 Reftek125 (Texan) seismic recorders, with an average spacing of 1 km. For the calculations, we used the Rayinvr, Vmed and Zplot programs for ray tracing, model modification and phase picking. The initial result show that: 1)the depth of low velocity sediment cover ranges from 0.6 to 2.7 km (velocity: 2.8~5.6 km/s); 2)the depth of basement is 5.6~10 km (the depth of basement under the granitoid belt deepens to 10 km and velocity increases to 6.2 km/s); 3)the upper crust extends to a depth of 15.5~21 km and has the P-wave velocities between 5.6 and 6.4 km/s; 4)the thickness of the lower crust ranges from 22~28 km(velocity: 6.4~6.9 km/s); and 5)the depth of Moho varies from 39.5 km under the granitoid belt to 49 km under the Yanshan orogen. Based on these results, we can preliminarily deduce that: 1) the concave depression of the Moho observed represents the root of the Yanshan orogen, and it may prove that the orogen is dominated by thick-skinned tectonics; 2) the shape of velocity variations under the granitoid belt is suggestive of a magma conduit.

    We herein present the case of a 78-year-old man with an incidental finding of a solid hepatic mass without symptoms and only a laparotomic cholecystectomy for acute cholecystitis in the past surgical history. A colonoscopy, a magnetic resonance imaging scan, a positron emission tomography scan, and a computed tomography scan completed the preoperative workup: a neoplastic lesion 4.3×3 cm in size was diagnosed at segments IV and V, associated with a neoplastic involvement of the splenic flexure without signs of colonic occlusion. After colonic resection, a frozen section on a granulomatous-like tissue at gastric border suggested a diagnosis of an adenocarcinoma of bilio-pancreatic type, changing the surgical strategy to include gastric resection and hepatic pedicle node dissection. The discussion turns around the idea that a final diagnosis of colon cancer with regional nodal involvement (pT3N1) and metastatic gallbladder cancer with multiple peritoneal seedings cannot be excluded.

    Full Text Available Los pacientes con demencia tipo Alzheimer (DTA suelen presentar problemas en la toma de decisiones (TD, incluso ya en fase leve. Diversos estudios han analizado el funcionamiento de los mecanismos cognitivos en los procesos de TD, especialmente en situaciones de incertidumbre. Una de estas aproximaciones es la hipótesis del marcador somático a través de la Iowa Gambling Task (IGT y el índice Gambling (IG. Uno de los problemas es la inespecificidad de los indicadores de la IGT, por ello se han propuesto modelos explicativos para solventar estas carencias, como el Prospective Valence Learning (PVL. En este trabajo, aplicamos la IGT a 10 pacientes y 10 controles. Analizamos los parámetros del PVL: aversión a las pérdidas (λ regla de utilidad (α, recencia (A y consistencia (c, y la evolución de la tarea en función de las elecciones ventajosas. Nuestros resultados muestran que el rendimiento de los controles es mejor que el de pacientes DTA, aunque en las fases iniciales no hay diferencias, estas se ciñen a los dos bloques finales. En los parámetros del PVL se obtienen diferencias en α y c y en menor medida en λ. A partir de los parámetros del PVL podemos caracterizar el proceso de toma de decisiones de los pacientes DTA, como sensibles a las pérdidas, más influenciados por las elecciones inmediatas y un nivel de consistencia muy bajo, que indica estrategias de elección aleatoria.

Un análisis de decisiones clínicas (modelo de árbol de decisiones se utilizó para definir el tratamiento del tercer molar retenido asintomático. Las probabilidades para los desenlaces fueron obtenidos de la literatura. Las utilidades o preferencia fueron asignadas independientemente por pacientes y cirujanos. Resultados. La alternativa más conveniente para los pacientes fue la No extracción, mientras que para los cirujanos, la Si extracción. La decisión de los cirujanos resultó inestable al efectuar el análisis de sensibilidad bivariado al modificarse algunos valores asignados en el modelo, mientras que se mantuvo entre los pacientes. Conclusión. Las diferencias en las utilidades asignadas por pacientes y cirujanos, podrían deberse a la falta de información ofrecida al grupo de pacientes y a la diferencia de intereses entre unos y otros, si esto se corrige, la discrepancia entre los dos grupos logrará cerrarse, y a lo mejor podrían llegar a encontrar que la misma decisión es verdaderamente la más conveniente para ambos.

El propósito de esta práctica es lograr que el sector forestal siga siendo competitivo a nivel internacional, para tal objetivo se hace necesario optimizar las diferentes actividades que participan en la producción forestal. Los costos asociados a la faena de cosecha forestal son los de mayor incidencia dentro de los planes operativos, por ello es importante tener conocimiento de sus efectos reales en el cálculo de las tarifas. El trabajo realizado consistió en desarrollar un software de aplicación y consulta para la estructuración y tarifa a cobrar para una faena de cosecha forestal mecanizada, desarrollado en el lenguaje de programación Visual Basic. SICOFOR 1.0.1 al ser comparado con otras planillas de cálculo como por ejemplo las desarrolladas en Microsoft Excel entrega una mayor facilidad de trabajo, permite actualizar las bases de datos de la maquinaria a utilizar, personal, administración e implementación de trabajo para cada sistema de aprovechamiento, además entrega detalladamente la tarifa a cobrar. Aunque realmente los que fijan las tarifas de los diferentes servicios son las empresas demandantes de los servicios, el desarrollo del programa como herramienta de apoyo a la toma de decisiones, sigue siendo útil para comparar la tarifa que la empresa forestal mandante ofrece y los costos reales del servicio de cosecha, para tomar la decisión de aceptar o desestimar el negocio.

Se asume un doble objetivo analítico y práctico: por un lado, analizar la forma como los estudiantes construyen discursivamente significados identitarios vinculados con la toma de decisiones sobre su futuro; por otro, ofrecer a los orientados herramientas que, a modo de dispositivo re-mediador, faciliten la tarea reflexiva que supone la construcción y proyección de la propia carrera académica y laboral. Se concluye que el uso reflexivo de narrativas autobiográficas permite integrar la orientación vocacional en el contexto social, cultural e institucional en que se produce, logrando así una mayor significatividad e impacto en la vida del orientado.

    Full Text Available Este trabajo de investigación se enfoca en la lógica difusa. Identifica de qué manera sirve para la selección de personal y qué publicaciones relevantes existen acerca de su efectividad en el escenario empresarial. La revisión realizada se llevó a cabo a partir de una búsqueda en bases de datos especializadas. Se encuentra que la fuzzy logic puede ofrecer al proceso de selección de personal algo de certidumbre, en particular en la toma de decisiones que lo acompaña. Puede contribuir también en el proceso de identificación de la persona más adecuada para realizar un conjunto de actividades, de acuerdo, además, con su perfil psicológico. Su uso ayuda, en efecto, a disminuir la ambigüedad y la subjetividad inherentes a la decisión en estos procesos. Esto, dado que los resultados de las pruebas psicométricas y de las entrevistas no son discrecionales, ellas se acompañan, usualmente, de múltiples criterios de asignación de valor.

    To develop and validate an instrument to assess environmentally conscious eating (Green Eating [GE]) behavior (BEH) and GE Transtheoretical Model constructs including Stage of Change (SOC), Decisional Balance (DB), and Self-efficacy (SE). Cross-sectional instrument development survey. Convenience sample (n = 954) of 18- to 24-year-old college students from a northeastern university. The sample was randomly split: (N1) and (N2). N1 was used for exploratory factor analyses using principal components analyses; N2 was used for confirmatory analyses (structural modeling) and reliability analyses (coefficient α). The full sample was used for measurement invariance (multi-group confirmatory analyses) and convergent validity (BEH) and known group validation (DB and SE) by SOC using analysis of variance. Reliable (α > .7), psychometrically sound, and stable measures included 2 correlated 5-item DB subscales (Pros and Cons), 2 correlated SE subscales (school [5 items] and home [3 items]), and a single 6-item BEH scale. Most students (66%) were in Precontemplation and Contemplation SOC. Behavior, DB, and SE scales differed significantly by SOC (P development and preliminary validation of this 25-item GE instrument provides a basis for assessment as well as development of tailored interventions for college students.

    2011-01-01

    Full Text Available El presente trabajo pretende analizar el efecto del sexo sobre el desempeño en una tarea compleja de toma de decisiones. El rendimiento en tareas de logro está ligado a las dinámicas autorreguladoras, como la autoeficacia, las metas personales y el compromiso con la tarea, determinadas por variables disposicionales como la orientación de las metas o, estudiada más recientemente, la orientación hacia los errores. Concretamente, tratamos de comparar los procesos de autorregulación y factores disposicionales entre chicos y chicas estudiantes universitarios ante la realización de una tarea que simula la implementación de la innovación y el cambio en una organización. Los resultados muestran que son las mujeres quienes manifiestan una clara tendencia a comunicar los errores y se muestran menos preocupadas por demostrar competencia ante los demás. Sin embargo, ante las dificultades mostrarían sentirse menos capaces de afrontarlas, más angustiadas y se plantearían metas más bajas para su desempeño, lo que les llevaría finalmente a alcanzar un rendimiento inferior.

    To determine whether or not different therapies have distinct patterns of change, it is useful to investigate not only the end result of psychotherapy (outcome) but also the processes by which outcomes are attained. The present study subjected data from the National Institute of Mental Health Treatment of Depression Collaborative Research Program to survival analyses to examine whether the process of psychotherapy, as conceptualized by the phase model, differed between psychotherapy treatment approaches. Few differences in terms of progression through phases of psychotherapy were identified between cognitive behavior therapy and interpersonal therapy. Additionally, results indicate that phases of psychotherapy may not represent discrete, sequentially invariant processes.

    2018-02-01

    This paper introduces an original mathematical description for describing agents' decision-making process in the case of problems affected by both individual and collective behaviors in systems characterized by nonlinear, path dependent, and self-organizing interactions. An application to artificial financial markets is proposed by designing a multi-agent system based on the proposed formalization. In this application, agents' decision-making process is based on fuzzy logic rules and the price dynamics is purely deterministic according to the basic matching rules of a central order book. Finally, while putting most parameters under evolutionary control, the computational agent-based system is able to replicate several stylized facts of financial time series (distributions of stock returns showing a heavy tail with positive excess kurtosis, absence of autocorrelations in stock returns, and volatility clustering phenomenon).

  7. Reducing the impact bias in judgments of post-decisional affect

    Full Text Available People overestimate their affective reactions to future events and decisions --- a phenomenon that has been termed ``impact bias.'' Evidence suggests that completing a diary detailing events contemporaneous with the focal one de-biases judgments of affect. It is generally assumed that this is because diary completion helps people to realize that they will be distracted from the focal event. However, there is another possibility: de-biasing may occur because diary completion interferes with the processing responsible for the bias. In a first experiment, we showed that diary completion also lowers affect associated with past decisions. In a second experiment, we showed that solving anagrams has the same effect. A third experiment demonstrates that this is not because affect judgments are influenced by mood changes brought about by solving anagrams. Indeed, monitoring moods lowered affect in the same way as diary completion. It appears that cognitive tasks of any sort interfere with the processing required by judgments of affect.

    Full Text Available Las decisiones estratégicas de inversión son actividades cruciales para el desarrollo de una organización. Los proyectos de inversión se encuentran expuestos a diversos tipos de riesgo: financiero, político, de mercado, entre otros. Aunque se pueden mencionar varios tipos de metodologías de medición que intentan incluir el riesgo en la valoración de proyectos, la mayoría de ellas tiene falencias, que en todo caso pueden ser abordadas para dar lugar a mejores indicadores de bondad económica y financiera. El presente trabajo aborda el problema de valoración económica de proyectos, y en particular, los problemas del indicador de utilidad económica, Valor Presente Neto (VPN cuando se calcula sobre un único escenario estático del proyecto. Mediante una combinación del cálculo del costo promedio ponderado de capital (CPPC -Weighted Average Cost of Capital (WACC- y el uso de métodos de valoración de riesgo que tienen en cuenta la relación entre riesgo- retorno esperado, el resultado principal que se obtiene en este trabajo es un método de evaluación de proyectos, con aplicación principalmente en decisiones estratégicas del sector real, que incluye explícitamente la valoración del riesgo inherente a tales decisiones. Para ilustrar el criterio propuesto, se presentan dos casos de aplicación, el primero sobre selección de tecnología y el segundo sobre decisiones de renovación de cultivos de caña de azúcar.

El presente estudio se desarrolló en los municipios de Guachucal y Cumbal, departamento de Nariño, Colombia con el propósito de identificar los criterios y decisiones claves que toman los agricultores, en el manejo de la cobertura arbórea en fincas ganaderas productoras de leche. Las decisiones, fueron modeladas y simuladas en el programa Netica 2.6. Con las respuestas obtenidas se diseñaron modelos generales de decisión, donde se obtuvo cuatro eventos principales y de mayor influencia en el manejo de la cobertura arbórea, 1 evento poda, 2 evento control de maleza, 3 evento siembra de árboles y 4 evento aprovechamiento de árboles. Las frecuencias, permitieron estimar la probabilidad de cada decisión e influencia de las variables con respecto a los eventos para su modelación y simulación. Además, para profundizar sobre el proceso de toma de decisiones se plantearon escenarios relacionados con las condiciones agroecológicas de la finca, el manejo de la unidad productiva y el entorno en el que opera la finca. Así mismo se analizaron las principales limitantes para el manejo y establecimiento de la cobertura arbórea. El evento de mayor importancia para el manejo de la cobertura arbórea es la poda, debido a su valor en la obtención de leña como combustible, este factor influye en la zona para que las cobertura arbóreas se incrementen como cercas vivas.

    BACKGROUND AND GOAL: Screening of fetal anomalies is assumed as a necessary measurement in antenatal cares. The screening plans aim at empowerment of individuals to make the informed choice. This study was conducted in order to compare the effect of group and face-to-face education and decisional conflicts among the pregnant females regarding screening of fetal abnormalities. METHODS: This study of the clinical trial was carried out on 240 pregnant women at education course were held in two weekly sessions for intervention groups during two consecutive weeks, and the usual care was conducted for the control group. The rate of informed choice and decisional conflict was measured in pregnant women before education and also at weeks 20–22 of pregnancy in three groups. The data analysis was executed using SPSS statistical software (version 16), and statistical tests were implemented including Chi-square test, Kruskal–Wallis test, Wilcoxon test, Mann–Whitney U-test, one-way analysis of variance test, and Tukey's range test. The P education group, 64 members (80%) in group education class, and 20 persons (25%) in control group had the informed choice regarding screening tests, but there was no statistically significant difference between two individual and group education classes. Similarly, during the postintervention phase, there was a statistically significant difference in mean score of decisional conflict scale among pregnant women regarding screening tests in three groups (P = 0.001). DISCUSSION AND CONCLUSION: With respect to effectiveness of group and face-to-face education methods in increasing the informed choice and reduced decisional conflict in pregnant women regarding screening tests, each of these education methods may be employed according to the clinical environment conditions and requirement to encourage the women for conducting the screening tests.

    Processing has major impacts on both the structure and composition of food and hence on nutritional value. In particular, high consumption of ultra-processed foods (UPFs) is associated with increased risks of obesity and diabetes. Unfortunately, existing food indices only focus on food nutritional content while failing to consider either food structure or the degree of processing. The objectives of this study were thus to link non-nutrient food characteristics (texture, water activity (a w ), glycemic and satiety potentials (FF), and shelf life) to the degree of processing; search for associations between these characteristics with nutritional composition; search for a holistic quantitative technological index; and determine quantitative rules for a food to be defined as UPF using data mining. Among the 280 most widely consumed foods by the elderly in France, 139 solid/semi-solid foods were selected for textural and a w measurements, and classified according to three degrees of processing. Our results showed that minimally-processed foods were less hyperglycemic, more satiating, had better nutrient profile, higher a w , shorter shelf life, lower maximum stress, and higher energy at break than UPFs. Based on 72 food variables, multivariate analyses differentiated foods according to their degree of processing. Then technological indices including food nutritional composition, a w , FF and textural parameters were tested against technological groups. Finally, a LIM score (nutrients to limit) ≥8 per 100 kcal and a number of ingredients/additives >4 are relevant, but not sufficient, rules to define UPFs. We therefore suggest that food health potential should be first defined by its degree of processing.

    It is common belief that the interaction between antimatter and ordinary solid matter is dominated by annihilation. However, non-destructive processes may play a relevant role too. One century ago E. Rutherford wrote about the "diffuse reflection" of alpha and beta particles by thin layers of different metals: "The observations ... of Geiger and Marsden on the scattering of alpha rays indicate that some of the alpha particles must suffer a deflexion of more than a right angle at a single encounter.... It will be shown that the main deductions from the theory are independent of whether the central charge is supposed to be positive or negative". Although the theory of electromagnetic scattering is in first approximation independent of the relative sign of the colliding particles, in the case where projectile antiprotons are shot against a wall of solid matter the Rutherford diffuse reflection mechanism competes with the annihilation process. So it is not obvious at all that a relevant part of an antiproton beam...

    To identify decisional needs of women, their partners and health professionals regarding prenatal testing for Down syndrome through a systematic review. Articles reporting original data from real clinical situations on sources of difficulty and/or ease in making decisions regarding prenatal testing for Down syndrome were selected. Data were extracted using a taxonomy adapted from the Ottawa Decision-Support Framework and the quality of the studies was assessed using Qualsyst validated tools. In all 40 publications covering 32 unique studies were included. The majority concerned women. The most often reported sources of difficulty for decision-making in women were pressure from others, emotions and lack of information; in partners, emotion; in health professionals, lack of information, length of consultation, and personal values. The most important sources of ease were, in women, personal values, understanding and confidence in the medical system; in partners, personal values, information from external sources, and income; in health professionals, peer support and scientific meetings. Interventions regarding a decision about prenatal testing for Down syndrome should address many decisional needs, which may indeed vary among the parties involved, whether women, their partners or health professionals. Very little is known about the decisional needs of partners and health professionals.

However, this technique is still little known and there is scarce evidence about its applicability to solve real-world problems. In this paper we propose to use belief merging in order to solve everyday decision-making problems, in which participants with the same level have contradictory opinions, by “merging” these opinions and generating a common non-contradictory opinion representing the views of the majority.

    The National Human Papillomavirus (HPV) Vaccination Program in Australia commenced in 2007 for females and in 2013 for males, using the quadrivalent HPV vaccine (HPV 6,11,16,18). Thus far, we have demonstrated very substantial reductions in genital warts and in the prevalence of HPV among young Australian women, providing early evidence for the success of this public health initiative. Australia has a long history of school-based vaccination programs for adolescents, with comparatively high coverage. However, it is not clear what factors promote success in a school vaccination program. The HPV.edu study aims to examine: 1) student knowledge about HPV vaccination; 2) psycho-social outcomes and 3) vaccination uptake. HPV.edu is a cluster randomised trial of a complex intervention in schools aiming to recruit 40 schools with year-8 enrolments above 100 students (approximately 4400 students). The schools will be stratified by Government, Catholic, and Independent sectors and geographical location, with up to 20 schools recruited in each of two states, Western Australia (WA) and South Australia (SA), and randomly allocated to intervention or control (usual practice). Intervention schools will receive the complex intervention which includes an adolescent intervention (education and distraction); a decisional support tool for parents and adolescents and logistical strategies (consent form returns strategies, in-school mop-up vaccination and vaccination-day guidelines). Careful process evaluation including an embedded qualitative evaluation will be undertaken to explore in depth possible mechanisms for any observed effect of the intervention on primary and secondary outcomes. This study is the first to evaluate the relative effectiveness of various strategies to promote best practice in school-based vaccination against HPV. The study aims to improve vaccination-related psychosocial outcomes, including adolescent knowledge and attitudes, decision-making involvement, self

    2008-01-01

    This chapter presents psychological issues and processes in adolescent patients who have also migrated or relocated from one country to another. Theoretical perspectives related to attachment processes illumine both migration and adolescence as changes for which secure bases are most needed, lost, and sometimes rediscovered. The psychodynamic processes underlying the difficulties encountered by such adolescents, and their meaning, are presented. Relationships with parents, which normally go through separation-individuation and renegotiation of the oedipal crisis, both of which are central to adolescence, are disrupted by migration. Migration poses new challenges and choices while identity formation is evolving during adolescence. These include adopting a new identity, embracing and letting go of the old, and accepting and integrating the new. The dual relationship with identity finds expression, for example, in language. Fluctuations in understanding and not understanding the new and the old language represent the ambivalence toward the new and the old. The developmental roller-coaster of adolescence, which involves more intense use of defense mechanisms, is heightened during immigration. Processes of idealization (of parents, therapist, old country, new culture) rapidly fade with the devaluation of the same targets. Mechanisms of splitting between good and bad, as well as massive repression of issues that are too hard to deal with at this crossroad, are profuse. Hopeful fantasies of rebirth are concurrent with despair, depression, and, in some cases, suicidal thoughts and attempts. Excerpts from a case in psychodynamic psychotherapy are presented, focusing on the evolving new balances: integrating the old and the new by maintaining attachments to the one while forming attachments to the other; relinquishing and mourning the lost paradise of childhood, as well as the old country, friends, culture, smells, and tastes; accepting disappointments when the shining new

    A catheter tip oximeter is described consisting of a cardiac catheter containing optical fibers, and incandescent light source, a light detection unit and a processing unit. Half of the optical fibers guide the light to the blood at the tip of the catheter, the other half the backscattered (reflected) light to the detection unit. The detection unit contains a dichroic mirror, transmitting most of the light with lambda less than 800 nm and reflecting most of the light with lambda greater than 900 nm, thus splitting the light into two beams. These pass through interference filters with nominal wavelengths of 640 and 920 nm respectively, and are focused on silicium barrier layer photocells. The photocell signals are amplified and fed into a divider giving the ratio of measuring (R640) and compensating (R920) photocell output. The relationship between log R640/R920 and oxygen saturation is represented by a slightly curved line. The relation may be linearized by subtracting a constant voltage from the divided output before taking the logarithm. The slope of the calibration line is dependent on the total haemoglobin concentration. Nonetheless an average calibration line can be used between 70 and 100% oxygen saturation. For 78 measurements of pig blood samples in this range (haemoglobin concentration between 96 and 161 g.1(-1)), the standard deviation of the difference between the fiberoptic oximeter and a Radiometer OSM1 oxygen saturation meter was 1.9% saturation, for 152 samples over the entire saturation range the standard deviation of the difference was 3.1% saturation. The influence of the flow velocity of blood on the light reflection depends on wavelength as well as on oxygen saturation. Therefore, complete compensation for the flow effect is not possible by simple means.

    Patients suffering from musicogenic epilepsy have focal seizures triggered by auditory stimuli. In some of these patients, the emotions associated with the music appear to play a role in the process triggering the seizure, however, the significance of these emotions and the brain regions involved are unclear. In order to shed some light on this, we conducted fMRI and EEG in a case of musicogenic epilepsy. In a 32-year-old male patient with seizures induced by a specific piece of Russian music, we performed video-EEG monitoring as well as simultaneous fMRI and EEG registration. Video-EEG monitoring revealed a left temporo-frontal epileptogenic focus. During fMRI-EEG co-registration, BOLD signal alterations were not only found in the epileptogenic focus but also in areas known for their role in the processing of emotions. Prior to a seizure in some of these areas, BOLD contrasts exponentially increased or decreased. These results suggest that in our case, dysfunction of the regulation processes of the musically-induced emotions, and not the musical stimulus itself, led to the seizures.

    Full Text Available El objetivo principal que persigue el presente trabajo es mostrar empíricamente en un nuevo contexto, que el mecanismo que rige el proceso de toma de decisiones a la hora de optar por consumir bienes culturales no se ajusta enteramente a la visión racional y egoísta del ser humano propuesta por la economía clásica. Para alcanzar este objetivo se planteó un diseño experimental con tres grupos (dos experimental y uno control a los que se les daba la opción de elegir hipotéticamente entre reclamar la devolución del dinero de la entrada a la salida de diferentes eventos culturales (decisión egoísta o no hacerlo (decisión no egoísta. Para analizar los resultados se realizó una prueba binomial para determinar si la diferencia de proporciones entre las respuestas afirmativas y negativas eran o no significativas. Los resultados obtenidos indican que en la mayoría de las situaciones los participantes se negaban a reclamar la devolución del dinero de la entrada a la salida del evento cultural, actuando así de manera no-racional bajo la visión económica clásica. Estos resultados tendrían, a efectos prácticos, un aumento en el número de espectadores que asisten a actos culturales.

    Full Text Available L’articolo propone una metodologia di valutazione della camminabilità (walkability urbana ed il rispettivo strumento software di supporto alla decisione ed alla pianificazione urbanistica. Nella parte introduttiva discutiamo la rilevanza del concetto di camminabilità per la qualità urbana ed offriamo un suo inquadramento teorico all’interno dell’approccio alle capacità (capability approach. La parte centrale è dedicata alla presentazione del modello spaziale e multicriteriale di valutazione della camminabilità. La nostra costruzione della camminabilità nel modello propone un certo ribaltamento di prospettiva rispetto ai metodi sinora proposti: anziché valutare quanto un determinato luogo è in sé camminabile, il punteggio di camminabilità calcolato riflette come e verso dove una persona può intraprendere una camminata a partire da quel luogo; in altre parole, non quanto è camminabile, ma invece qual è la camminabilità di cui il luogo è dotato. Per questo, il punteggio di camminabilità combina tre componenti: (1 il numero di destinazioni di interesse/opportunità urbane raggiungibili a piedi; (2 le loro distanze; (3 la qualità dei percorsi pedonali verso queste destinazioni. La qualità dei percorsi pedonali è valutata in base a diversi attributi rilevanti per la camminabilità, che fanno riferimento a caratteristiche proprie della strada e dell’ambiente circostante in grado di contribuire a rendere il percorso piacevole, sicuro ed attrattivo. A titolo illustrativo viene nella terza parte dell’articolo presentato un esempio di applicazione del modello alla città di Alghero.

    Understanding how people interpret environmental change and develop practices in response to such change is essential to comprehend human resource use. In the cosmology of the American indigenous peoples, as among the Mapuche people, freshwater systems are considered a living entity, where animals have an enormous role to play in the universe of meaning. However, human adaptive responses to freshwater system dynamics are scarcely examined. In this work a survey is carried out in three Mapuche communities of Argentine Patagonia to assess their traditional knowledge of the fishes and other non-human living beings that inhabit lakes and rivers. Both material and symbolic aspects are included, as are the differences in knowledge and use of the fishes between past and present times. Our methods were based on a quali-quantitative fieldwork approach. In-depth interviews were carried out with 36 individuals from three rural Mapuche populations in Neuquén province (Patagonia, Argentina). Free listing was used for inquiring about fish knowledge and use. Fishes were identified scientifically and ethnotaxonomically. In-depth analysis of the discourses was conducted, documenting the recognition, perception, and cultural significance of fluvial environments and their inhabitants. Quantitative survey results were analyzed with categorical statistical methods. The body of knowledge of the communities studied reflects the socio-environmental changes experienced by Patagonian freshwater bodies. According to local perception, non-human beings live in these water bodies, guarding the environment, and they should not be disturbed. At present, five different fish species are identified, three of which are exotic, having been introduced at the beginning of the 20th century by the white man. These exotic trout (Oncorhynchus mykiss and Salvelinus fontinalis) are considered ill omens, indicators of the white man's presence, and therefore their appearance presages negative events for the

    The processes of oil extraction from deposit are linked with the movement of multi-phase multi-component media, which are characterized by non-equilibrium and non-linear rheological features. The real behavior of layered systems is defined by the complexity of the rheology of moving fluids and the morphology structure of the porous medium, and also by the great variety of interactions between the fluid and the porous medium [Hasanov and Bulgakova, 2003]. It is necessary to take into account these features in order to informatively describe the filtration processes due to the non-linearity, non-equilibrium and heterogeneity that are features of real systems. In this way, new synergetic events can be revealed (namely, a loss of stability when oscillations occur, and the formation of ordered structures). This allows us to suggest new methods for the control and management of complicated natural systems that are constructed on account of these phenomena. Thus the layered system, from which it is necessary to extract the oil, is a complicated dynamical hierarchical system. A comparison is provided of non-equilibrium effects of the influence of independent hydrodynamic and electromagnetic induction on an oil layer and the medium which it surrounds. It is known that by drainage and steeping the hysteresis effect on curves of the relative phase permeability in dependence on the porous medium's water saturation in some cycles of influence (drainage-steep-drainage) is observed. Using the earlier developed 3D method of induction electromagnetic frequency geometric monitoring, we showed the possibility of defining the physical and structural features of a hierarchical oil layer structure and estimating the water saturation from crack inclusions. This effect allows managing the process of drainage and steeping the oil out of the layer by water displacement. An algorithm was constructed for 2D modeling of sound diffraction on a porous fluid-saturated intrusion of a hierarchical

    The new challenges in the field of Health and Safety at Work require the implementation of more comprehensive and participatory interventions, in order to have a real impact on the working conditions. Matriosca Model has sought over the years to involve workers in the construction of new working conditions, promoting transformation through training and recreating training from the transformation. This article seeks to present some of the results of the implementation of the Matriosca Model on a chemicals industrial company regarding the many changes that it promoted, how these changes have evolved through time, how the dimensions of training and transformation interact and what the participants' perception of the intervention was. The conclusions drawn allow a richer evaluation of the process, which can enhance the intercommunicating nature between training and transformation, and what impact this has on the actual work.

The social program is analyzed in various key aspects of the implementation process. These issues were addressed through qualitative research with broad objectives and a comprehensive approach. We reflect on a research breakthrough that privileges the perceptions and representations of technical teachers who worked in this Program. Also, we make some contributions to improve future actions and teacher training. Six focus groups were formed and it is estimated that the input generated will be useful for planning better teaching practices and specific training of future teachers.

    Full Text Available Since the second half of the 20th century, the developments in the field of information technologies and the Internet have introduced significant changes in both traditional and distance learning and e-learning has become one of the fundamental elements of education. While e-learning and educational use of the Internet have been getting more common, higher education institutions have been reviewing and restructuring their own positions in line with the developments in these areas. Around 50 universities in Turkey started remote education programs. Furthermore new tools to promote face to face education continue to exist on the Internet and to increase the efficiency of the courses. Since the beginning of the second part of2000s, the Turkish Academy of Sciences (TÜBA has been leading the work for the implementation of the project of open course materials in order to improve the effectiveness of face to face courses and it has been supported by a number of universities. In the study, the situation in Gazi University was evaluated; the informatics system and the open course materials developed by the university in the process of e-learning were examined and the study also determined the extent to which students use the Internet for educational purposes. The result of the research shows that the efforts for creating open course materials in Gazi University have not proved sufficient yet. According to the results of the research, it was determined that the students’ belief in their self-efficacy in the educational use of the Internet was at medium level. Gender and educational status of father were found to be related with self-efficacy. On the other hand, it was revealed that self-efficacy was not linked to the educational status of mother, having a computer, or taking computer classes in high school.

    The problem of agreement among interests in the management of natural resources is complex with interactions difficult to measure. Watershed users have several objectives that impact in the short run the environment. Multi objective decision theory considers interest, options and impacts of possible actions. Considering that the Irrigation Districts (ID) are the lower end of the gradient that defines a watershed, the ID 017 was used as study case for use of the Decision Support System called Facilitator which is a software tool to support decision making processes with the use of decision alternatives, order of hierarchy, score functions and linear programming for identifying best decision alternatives for the management of a given problem. For the Irrigation District 017, it has been concluded that to help solve the overall problem of irrigation water productivity, first water needs to be priced, to train water users and delivering water by volume. Out of the eight alternatives analyzed, all did score better than the actual management.

    Full Text Available En esta época de respeto por la ciencia médica y por la responsabilidad gerencial, las organizaciones de salud deben rendir cuentas por sus acciones con creciente frecuencia. La época en que se determinaban las prioridades y se tomaban las decisiones sobre bases políticas o acatando el consejo intuitivo de asesores respetados y bien intencionados ha dado paso gradualmente a una era que valora la demostración de efectividad y eficiencia. Las decisiones relativas a las prioridades y a los programas deben basarse firmemente en conocimientos comprobados y someterse a evaluación continua. Esta transición requiere promover el pensamiento crítico en todos los ámbitos. Surge entonces la siguiente pregunta: ¿Cómo podemos promover el razonamiento crítico en los servicios de salud para fijar prioridades, adoptar decisiones acertadas y poner en práctica iniciativas efectivas? En otras palabras, ¿cómo podemos pasar de la evidencia al desempeño? Una pregunta aún más básica es ¿por qué debemos fijar prioridades?In today's world, with its respect for the medical sciences and demand for administrative accountability, health institutions are publicly responsible for their actions to an unprecedented degree. Making decisions and setting priorities on the basis of politics or unvalidated expert opinions is no longer acceptable. Instead, proven efficiency and effectiveness, as demonstrated by scientific evidence under continuous evaluation, are essential to decision-making. The need for applying rational criteria makes it necessary to explore a fundamental question: How can we promote critical reasoning within health services so as to adequately set priorities, make proper decisions, and launch effective interventions? In other words, how can we move from evidence to performance and why set priorities at all?

    Full Text Available Background and Objectives: Constructs of behavioral models such as trans-theoretical model can be associated with healthy eating behaviors like increasing fiber intake. They can also be effective in improving these behaviors in patients with diabetes. This study aimed to assess the association of self-efficacy and decisional balance with stages of change for fiber intake and glycemic control in patients with type 2 diabetes. Materials and Methods: A cross-sectional study was conducted on 145 literate male and female patients with type 2 diabetes (aged 30 to 65 years they were randomly selected from the patients’ list of “Charity Foundation for Special Diseases” and ”Iranian Diabetes Society” in Tehran-Iran. Stages of change, self-efficacy, and decisional balance questionnaires were filled out, and three food records were used to assess their nutritional status. Blood samples were taken to assess fasting blood glucose, HbA1c, serum insulin, and insulin resistance. One-way ANOVA and logistic regression were used to analyze the data. The tests were done using the SPSS software (ver. 16. P<0.05 was considered significant. Results: 126 patients with type 2 diabetes completed the study. Participants’ mean age was 53.5±6.02 and 65% were men. Patients in post-action stages revealed higher self-efficacy than did those in pre-action stages (P=0.035. A relationship was observed between insulin resistance and self-efficacy (P=0.040. One unit increase in self-efficacy decreased the risk of insulin resistance by 12%, and each unit increase in decisional balance increased the chance of eating sufficient fiber by 2.2 times. There was also a significant relationship between the perceived cons (P<0.0001 and self-efficacy (P=0.037 with fiber intake after adjustment with confounders. Conclusions: This study suggests that there is a relationship between transtheoretical model constructs such as self-efficacy and decisional balance, especially cons, with
