    Full Text Available Knowledge about dismissal decision-making, particularly concerning the criteria used by managers in choosing who will be dismissed and why, is scarce. Considering the implications of such decisions for organizations and society, in this paper, we identify the seven most frequently used criteria in dismissal decisions and examine their importance for managers. We collected data through a survey among 385 managers and used the rational ranking and the multicriteria Analytic Hierarchy Process (AHP to analyze them. The results show that commitment, performance records, and trust have the greatest impact on the dismissal decision, whereas interpersonal relationship, growth potential, and professional experience are considered secondary criteria. These results contribute to extending our knowledge about dismissal decisions and showing the most relevant criteria in these choices and the relevance assigned to each of the criteria so that greater transparency can be achieved.

  2. THE IMPORTANCE OF CORPORATE BRANDS FOR DECISION MAKING IN THE BUSINESS-TO-BUSINESS CONTEXT

    Full Text Available The purpose of this paper is to provide a deeper understanding of the importance of the corporate brand for the business-to-business (B2B context, specifically concerning the buyer and supplier decision-making processes. The paper provides a literature review on tangible and intangible brand attributes, as well as their influence on perceived risks and emotions in decision making. The findings imply that business decision making is not solely rational, and that emotions matter a great deal. The conceptual framework thus presents the process of business decision making in which brand attributes play a focal role for both the buyer and supplier. Research implications include three aspects: the importance of corporate brands and their attributes for reducing a buyer´s perceived risks when choosing a new supplier, the role of corporate brands for strategies that suppliers are using when attracting potential buyers, and the effect of emotions on the mentioned processes. The paper offers a new comprehensive framework for studying decision-making in the B2B context and contributes to corporate branding and decision-making theory development.

    Full Text Available Background: In the neonatal care units of the University Hospitals of Zurich and Bern, the nurse´s role in ethical decision-making is well established. However, nurses often reported uncertainty with regard to introducing the premature infant’s situation from the nursing perspective in ethics rounds. Aims: To empower neonatal nurses in fulfilling their role in the multiprofessional decision-making process, we performed a practice development project. On the basis of the Iowa model we developed a checklist for presenting the nursing history of premature infants in an ethically competent and responsible way. Conclusions: The ‘checklist for nursing assessment in the context of ethical decision-making’, equips nurses for their professional contribution to ethics rounds, making them better prepared to present the nursing perspective in a structured and thorough manner. Implications for practice: The Iowa model supports practice development even with limited data availability The instrument invigorates the neonatal nurse´s role in the multiprofessional ethical decision-making process It is crucial to involve peers in practice development

  4. Why it is important to promote communication in the decision-making process

    Opportunity, nightmare, integrity and public confidence are all well-known words for us working in the nuclear area. Dealing with the outside world involves all those elements. However, having an active communication component in the decision making process can reduce the risk of getting into a nightmare situation and at the same time it contributes to gaining public confidence. The nuclear regulatory authority needs confidence to achieve effectiveness. Investing in trust is, therefore, necessary but requires a well-defined strategy and working methods. Moreover, it requires patience, and a culture of openness and relaxed attitude towards media. Finally, my experience tells me that it requires training of staff and motivators that constantly remind us of the importance of promoting communication in the decision-making process. In this paper I am presenting some insights into how SKI (Swedish Nuclear Power Inspectorate) works when preparing decision and why we are doing it. (author)

  5. Putting SEA in context: A discourse perspective on how SEA contributes to decision-making

    International Nuclear Information System (INIS)

    2009-01-01

    Over the last couple of years there is an ongoing debate in the environmental assessment literature about the contribution of Strategic Environmental Assessment (SEA) to public decision-making and how this can be understood and enhanced by better incorporating insights from policy analysis, planning theory and political sciences. By explicitly framing SEA as an element in a process where stakeholders with diverging interests struggle, acceptability of SEA processes and results by stakeholders has become an important element in SEA evaluation. In addition, the importance of other context variables, such as the institutional organisation, and the need for SEA to adapt to this context, is stressed. Thus far, publications in this area have been dealing with the operationalisation of SEA's 'contribution', typologies of roles that SEA can or should play in different policy settings and on factors that stimulate or impede SEA to play these roles. In this paper an alternative approach is suggested that starts from the deliberative processes around a particular policy issue or decision supported by SEA. Of particular interest are 'discourses': the frames through which groups of actors give meaning to aspects of the policy issues and decisions that are supported by SEA. Discourses do not only reflect conflicts of interests and power play, but also the ways in which actors perceive and understand aspects of the world. Decision-making is conceptualised as a 'system of competing discourse coalitions and their struggles to 'control shared meanings' and to gain acceptance of their framing of a policy issue' [Durning D. A review of Fischer and Forrester (1993) The argumentative turn in policy analysis and planning. Policy Sci 1995;28(1):102-8]. SEA is one of the events in this process that may impact upon dominant discourses. Discourse analysis allows for an understanding of arguments that are considered legitimate for (not) incorporating particular elements of SEA. In addition it

  6. Making health care safer: What is the contribution of health psychology?

    While health care brings great benefits, all treatments, and many investigations, carry some risk. As patients, we should be told of the risks of specific treatments but we are also at risk from failings in the health care system itself. We suggest that, while there are many examples of individual health psychologists who have made important contributions, this has not yet translated into a broader disciplinary engagement. Health psychologists have devoted much more attention to patients and devoted much less attention to the potentially huge impact of studying and intervening with staff, clinical practice, and organizations. We believe that there are considerable opportunities for health psychology to engage more closely with patient safety and, more importantly, that this would be of great benefit to both patients and staff. Statement of contribution What is already known on this subject? While health care brings great benefits, all treatments, and many investigations, carry some risk. Patients are also at risk from failings in the health care system itself. Studies using review of medical records in many countries have found that between 8% and 12% of patients in hospital suffer an unintended harm due to health care. What does this study add? There are many examples of individual psychologists who have made important contributions, but this has not yet translated into a broader disciplinary engagement. There are considerable opportunities for health psychology to engage more closely with patient safety. These include health behaviour change, teamwork, communication after medical error, diagnosis and decision making, organisational culture, and improving compliance with rules and standards. Psychologists providing a clinical service to specialist services in any area could expand their remit from supporting patients to a more general support and engagement with safety and quality initiatives. Health psychologists have models to understand the behaviour of people

    Decision making under risk is central to human behavior. Economic decision theory suggests that value, risk, and risk aversion influence choice behavior. Although previous studies identified neural correlates of decision parameters, the contribution of these correlates to actual choices is unknown. In two different experiments, participants chose between risky and safe options. We identified discrete blood oxygen level-dependent (BOLD) correlates of value and risk in the ventral striatum and anterior cingulate, respectively. Notably, increasing inferior frontal gyrus activity to low risk and safe options correlated with higher risk aversion. Importantly, the combination of these BOLD responses effectively decoded the behavioral choice. Striatal value and cingulate risk responses increased the probability of a risky choice, whereas inferior frontal gyrus responses showed the inverse relationship. These findings suggest that the BOLD correlates of decision factors are appropriate for an ideal observer to detect behavioral choices. More generally, these biological data contribute to the validity of the theoretical decision parameters for actual decisions under risk.

  10. Importance biasing quality criterion based on contribution response theory

    The report proposes a visual criterion of importance biasing both of forward and adjoint simulation. The similarity of contribution Monte Carlo and importance biasing random collision event distribution is proved. The conservation of total number of random trajectory crossings of surfaces, which separate the source and the detector is proposed as importance biasing quality criterion. The use of this criterion is demonstrated on the example of forward vs. adjoint importance biasing in gamma ray deep penetration problem. The larger amount of published data on forward field characteristics than on adjoint leads to the more accurate approximation of adjoint importance function in comparison to forward, for it adjoint importance simulation is more effective than forward. The proposed criterion indicates it visually, showing the most uniform distribution of random trajectory crossing events for the most effective importance biasing parameters and pointing to the direction of tuning importance biasing parameters.

    2017-09-01

    The aim is to investigate how encounters with peers affect an individual's meaning making in argumentation about socio-scientific issues, and how the individual's meaning making influences the argumentation at the collective level. The analysis is conducted using the analytical method "transactional argumentation analysis" (TAA) which enables in situ studies. TAA combines a transactional perspective on meaning making based on John Dewey's pragmatic philosophy with an argument analysis based on Toulmin's argument pattern. Here TAA is developed further to enable analysis that in detail clarifies the dynamic interplay between the individual and the collective—the intra- and the inter-personal dimensions—and the result of this interplay in terms of meaning making and learning. The empirical material in this study consists of a video-recorded lesson in a Swedish upper secondary school. The results show that the analysed student is influenced by peers when construing arguments, and thereby acts on others' reasoning when making meaning. Further, the results show that most of the additions made by the analysed student are taken further by peers in the subsequent discussion. This study shows how an individual's earlier experiences, knowledge and thinking contribute to the collective meaning making in the classroom.

    2013-03-01

    Environment migration research has sought to provide an account of how environmental risks and resources affect migration and mobility. Part of that effort has focused on the role of the environment in providing secure livelihoods through provisioning ecosystem services. However, many of the models of environment migration linkages fail to acknowledge the importance of social and psychological factors in the decision to migrate. Here, we seek to provide a more comprehensive model of migration decision-making under environmental change by investigating the attachment people form to place, and the role of the environment in creating that attachment. We hypothesize that environmental factors enter the migration decision-making process through their contribution to place utility, defined as a function of both affective and instrumental bonds to location, and that ecosystem services, the aspects of ecosystems that create wellbeing, contribute to both components of place utility. We test these ideas in four rural highland settlements in Peru sampled along an altitudinal gradient. We find that non-economic ecosystem services are important in creating place attachment and that ecological place attachment exists independently of use of provisioning ecosystem services. Individuals’ attitudes to ecosystem services vary with the type of ecosystem services available at a location and the degree of rurality. While social and economic factors are the dominant drivers of migration in these locations, a loss of non-provisioning ecosystem services leads to a decrease in place utility and commitment to place, determining factors in the decision to migrate. The findings suggest that policy interventions encouraging migration as an adaptation to environmental change will have limited success if they only focus on provisioning services. A much wider set of individuals will experience a decrease in place utility, and migration will be unable to alleviate that decrease since the factors

    To date, the study of collective behaviour has mainly focused on intraspecific situations: the collective decision-making of mixed-species groups involving interspecific aggregation-segregation has received little attention. Here, we show that, in both conspecific and heterospecific groups, the larvae of two species (Lucilia sericata and Calliphora vomitoria, calliphorid carrion-feeding flies) were able to make a collective choice. In all groups, the choice was made within a few minutes and persisted throughout the period of the experiment. The monitoring of a focal individual within a group showed that these aggregations were governed by attractive and retentive effects of the group. Furthermore, the similarity observed between the conspecific and heterospecific groups suggested the existence of shared aggregation signals. The group size was found to have a stronger influence than the species of necrophagous larvae. These results should be viewed in relation to the well-known correlation between group size and heat generation. This study provides the first experimental examination of the dynamics of collective decision-making in mixed-species groups of invertebrates, contributing to our understanding of the cooperation-competition phenomenon in animal social groups. © 2016 The Author(s).

    Numerous factors can impede or facilitate patients' medication decision-making and adherence to physicians' recommendations. Little is known about how patients and physicians jointly view issues that affect the decision-making process. Our objective was to derive an empirical framework of patient-identified facilitators to lupus medication decision-making from key stakeholders (including 15 physicians, 5 patients/patient advocates, and 8 medical professionals) using a patient-centered cognitive mapping approach. We used nominal group patient panels to identify facilitators to lupus treatment decision-making. Stakeholders independently sorted the identified facilitators (n = 98) based on their similarities and rated the importance of each facilitator in patient decision-making. Data were analyzed using multidimensional scaling and hierarchical cluster analysis. A cognitive map was derived that represents an empirical framework of facilitators for lupus treatment decisions from multiple stakeholders' perspectives. The facilitator clusters were 1) hope for a normal/healthy life, 2) understand benefits and effectiveness of taking medications, 3) desire to minimize side effects, 4) medication-related data, 5) medication effectiveness for "me," 6) family focus, 7) confidence in physician, 8) medication research, 9) reassurance about medication, and 10) medication economics. Consideration of how different stakeholders perceive the relative importance of lupus medication decision-making clusters is an important step toward improving patient-physician communication and effective shared decision-making. The empirically derived framework of medication decision-making facilitators can be used as a guide to develop a lupus decision aid that focuses on improving physician-patient communication. © 2016, American College of Rheumatology.

  18. A new importance measure for risk-informed decision making

    2000-01-01

    Recently, several authors pointed out that the traditional importance measures had limitations. In this study, the problem through an analysis at the parameter level was investigated and a new measure was introduced. The measure was based on small parameter variations and is capable of accounting for the importance of a group of components/parameters. The definition, computational steps, and an application of a new importance measure for risk-informed decision making were presented here. Unlike traditional importance measures, differential importance measure (DIM) deals with changes in the various parameters that determine the unavailability/unreliability of a component, e.g., failure rates, common-cause failure rates, individual human errors. The importance of the component unavailability/unreliability can be calculated from the importance of the parameters. DIM can be calculated for the frequency of initiating events, while risk achievement worth (RAW) is limited to binary events, e.g., component unavailability. The changes in parameters are 'small'. This is more realistic than the drastic assumption in RAW that the component is always down. DIM is additive. This allows the evaluation of the impact of changes, such as the relaxation of quality assurance requirements, which affect groups of parameters, e.g., the failure rates of a group of pumps. (M.N.)

  19. Contributions of the Medial Prefrontal Cortex to Social Influence in Economic Decision-Making.

    Economic decisions are guided by highly subjective reward valuations (SVs). Often these SVs are over-ridden when individuals conform to social norms. Yet, the neural mechanisms that underpin the distinct processing of such normative reward valuations (NVs) are poorly understood. The dorsomedial and ventromedial portions of the prefrontal cortex (dmPFC/vmPFC) are putatively key regions for processing social and economic information respectively. However, the contribution of these regions to economic decisions guided by social norms is unclear. Using functional magnetic resonance imaging and computational modeling we examine the neural mechanisms underlying the processing of SVs and NVs. Subjects (n = 15) indicated either their own economic preferences or made similar choices based on a social norm-learnt during a training session. We found that that the vmPFC and dmPFC make dissociable contributions to the processing of SV and NV. Regions of the dmPFC processed "only" the value of rewards when making normative choices. In contrast, we identify a novel mechanism in the vmPFC for the coding of value. This region signaled both subjective and normative valuations, but activity was scaled positively for SV and negatively for NV. These results highlight some of the key mechanisms that underpin conformity and social influence in economic decision-making. © The Author 2017. Published by Oxford University Press.

  20. The contribution of fusion to sustainable development

    The world demand for energy is projected to more than double over the next 50 years, indeed this will be essential to bring much of the world out of poverty. At the same time there is increasing pressure to substantially reduce atmospheric pollution, most notably of carbon dioxide. Together, these conflicting goals drive a need to produce enormous amounts of non-carbon energy supply, much greater than our total present energy supply. This presents a huge challenge. As one of very few options for large-scale, non-carbon future supply of energy, fusion has the potential to make an important contribution to sustained energy supplies. Fusion's advantages of large fuel reserves, low atmospheric emissions and high levels of safety make it an important consideration in future energy strategies. Conceptual designs of fusion power plants have been optimised against safety and environmental criteria; the results are described here and the outcomes compared with other energy sources. To make a contribution to sustainable development, fusion must be economically viable in a future energy market. The calculated costs of electricity from fusion show that, particularly in an energy market where environmental constraints are playing an increasing role, fusion can make an important contribution

    We reviewed the literature on shared decision making (regarding treatments in psychiatry), with a view to informing our understanding of the decision making process and the barriers that exist in clinical practice. Narrative review of published English-language articles. After culling, 18 relevant articles were included. Themes identified included models of psychiatric care, benefits for patients, and barriers. There is a paucity of published studies specifically related to antipsychotic medications. Shared decision making is a central part of the recovery paradigm and is of increasing importance in mental health service delivery. The field needs to better understand the basis on which decisions are reached regarding psychiatric treatments. Discrete choice experiments might be useful to inform the development of tools to assist shared decision making in psychiatry.

    The Dutch Health Care Performance Report, issued by the National Institute of Public Health and the Environment, aims to monitor health care performance in The Netherlands. Both the National Institute and the Ministry of Health wish to increase the contribution of the Report to health care policy-making. Our aim was to identify ways to achieve that. We used contribution mapping as a theoretical framework that recognizes alignment of research as crucial to managing contributions to policy-making. To investigate which areas need alignment efforts by researchers and/or policy-makers, we interviewed National Institute researchers and policy-makers from the Ministry of Health and assessed the process for developing the 2010 Report. We identified six areas where alignment is specifically relevant for enhancing the contributions of future versions of the Dutch Health Care Performance Report: well-balanced information for different ministerial directorates; backstage work; double role actors; reports of other knowledge institutes; data collection/generation and presentation forms. The contribution of health care performance reporting to policy-making is complex and requires continuous alignment efforts between researchers and policy-makers. These efforts should form an inseparable part of health care performance reporting and although this demands considerable resources, it is worth considering since it may pay back in better contributions to policy-making. © The Author(s) 2015.

    2003-05-01

    Significant conceptual work on shared decision making has taken place but there are still significant challenges in achieving it in routine clinical practice. This paper outlines what research has identified to date that may promote shared decision making, and the further research that is required to enable continuing progress. Greater understanding of the models of decision making and instruments to identify them in practice are still required. Specifying consumer competences, developing instruments to assess these and interventions to enhance them may also be important. Clarifying all these aspects may enable those charged with training professionals to improve the content of professional development programmes. This may be particularly important in the field of cancer treatments where the stakes are high-patients usually desire much information but their desire for involvement in decision making is more variable. The consequences of getting this balance right or wrong are significant with much to be gained or lost. Continued development and evaluation of decision aids and decision explorers that use interactive technology will also be important in identifying how to progress with consumer involvement. If we can learn these lessons, then wider implementation of shared decision making or consumer involvement may become a nearer prospect.

  6. The importance of learning when making inferences

    2008-03-01

    Full Text Available The assumption that people possess a repertoire of strategies to solve the inference problems they face has been made repeatedly. The experimental findings of two previous studies on strategy selection are reexamined from a learning perspective, which argues that people learn to select strategies for making probabilistic inferences. This learning process is modeled with the strategy selection learning (SSL theory, which assumes that people develop subjective expectancies for the strategies they have. They select strategies proportional to their expectancies, which are updated on the basis of experience. For the study by Newell, Weston, and Shanks (2003 it can be shown that people did not anticipate the success of a strategy from the beginning of the experiment. Instead, the behavior observed at the end of the experiment was the result of a learning process that can be described by the SSL theory. For the second study, by Br"oder and Schiffer (2006, the SSL theory is able to provide an explanation for why participants only slowly adapted to new environments in a dynamic inference situation. The reanalysis of the previous studies illustrates the importance of learning for probabilistic inferences.

    Previous functional imaging studies investigating the neural basis of strategic decision making in the prisoner's dilemma reported a correlation between cooperative behavior and dorsolateral prefrontal cortex (DLPFC) activity; however, the precise function of the DLPFC in establishing cooperation remains unclear so far. The present study investigated the causal role of the DLPFC in an iterative prisoner's dilemma game with transcranial magnetic stimulation (TMS). We discovered that disrupting the DLPFC with TMS decreased cooperation rates in comparison to control conditions, with this effect being most pronounced when the partner had defected previously. Thus, the current results suggest that the DLPFC contributes to strategic decision making in the prisoner's dilemma game.

  8. Mavericks versus team players: the trade-off between shared glory and making a personal contribution.

    Charlton, Bruce G

    2008-08-01

    The modern world is characterized by progressive specialization of function and ever-larger-scale coordination of these ever-more-specialized functions. More and more of science is done by increasing-sized teams of specialists, and the ability to engage in 'teamwork' is regarded as an almost essential attribute for most scientists. But teamwork does not suit all personality types. Some 'maverick' individuals would rather have personal credit for a relatively modest scientific contribution which they achieved (mostly) by themselves, than a share of credit in a much larger scientific contribution generated by a large team. The present system of medical science is organized to discourage mavericks and, on the whole, this is probably justifiable on the basis that scientists are not natural team players. Extra inducements are necessary to get people to adopt the relatively self-effacing behaviours necessary for building the large organizations of complementary specialists that are necessary for tackling many of the most intractable modern scientific problems. However, an ethos of teamwork does carry substantial disadvantages. Although most scientists are dispensable, and do not make a significant personal contribution, the very best scientists do make a difference to the rate of progress of science. And top notch scientists are wasted as team players. The very best scientists can function only as mavericks because they are doing science for vocational reasons. The highest intensity of personal commitment requires individual rewards from distinctive contributions. In conclusion, the current incentive system that encourages teamwork involves a trade-off. The majority of modestly talented scientists can probably achieve more when working as members of a team. But the very best scientists probably need to work as mavericks.

    The aim of this study on shared decision-making in the doctor-patient encounter about surgical treatment for early-stage breast cancer, conducted in a regional cancer centre in France, was to further the understanding of patient perceptions on shared decision-making. The study used methodological triangulation to collect data (both quantitative and qualitative) about patient preferences in the context of a clinical consultation in which surgeons followed a shared decision-making protocol. Data were analysed from a multi-disciplinary research perspective (social psychology and health economics). The triangulated data collection methods were questionnaires (n = 132), longitudinal interviews (n = 47) and observations of consultations (n = 26). Methodological triangulation revealed levels of divergence and complementarity between qualitative and quantitative results that suggest new perspectives on the three inter-related notions of decision-making, participation and information. Patients' responses revealed important differences between shared decision-making and participation per se. The authors note that subjecting patients to a normative behavioural model of shared decision-making in an era when paradigms of medical authority are shifting may undermine the patient's quest for what he or she believes is a more important right: a guarantee of the best care available. © 2014 John Wiley & Sons Ltd.

    As many scholars and practitioners in the environmental field turn to citizen science to collect robust scientific data as well as engage with wider audiences, it is crucial to build a more complete understanding of how citizen science influences and affects different interests within a social-ecological system. This research investigates how federal, state, and tribal natural resource managers interact with data from the Coastal Observation & Seabird Survey Team (COASST) project—a citizen science program that trains participants to monitor species and abundance of beach-cast birds on the Pacific Northwest Coast. Fifteen coastal and fisheries managers who previously requested COASST data were interviewed about how and why they used data from the project and were asked to describe how information gained from COASST affected their management decisions. Results suggest that broadly, managers value and learn from the program's capacity to gather data spanning a wide spatial-temporal range. This contribution to baseline monitoring helps managers signal and track both short- and long-term environmental change. More specifically, managers use COASST data in conjunction with other professional monitoring programs, such as the National Marine Fisheries Observer Program, to build higher degrees of reliability into management decisions. Although managers offered diverse perspectives and experiences about what the role of citizen science in natural resource management generally should be, there was agreement that agencies on their own often lack personnel and funding required to sufficiently monitor many crucial resources. Additionally, managers strongly suggested that COASST and other citizen science projects increased public awareness and support for agency decision-making and policies, and indirect yet important contribution to natural resource management.

    The nucleus accumbens (NAc) is a key node within corticolimbic circuitry for guiding action selection and cost/benefit decision making in situations involving reward uncertainty. Preclinical studies have typically assessed risk/reward decision making using assays where decisions are guided by internally generated representations of choice-outcome contingencies. Yet, real-life decisions are often influenced by external stimuli that inform about likelihoods of obtaining rewards. How different subregions of the NAc mediate decision making in such situations is unclear. Here, we used a novel assay colloquially termed the "Blackjack" task that models these types of situations. Male Long-Evans rats were trained to choose between one lever that always delivered a one-pellet reward and another that delivered four pellets with different probabilities [either 50% (good-odds) or 12.5% (poor-odds)], which were signaled by one of two auditory cues. Under control conditions, rats selected the large/risky option more often on good-odds versus poor-odds trials. Inactivation of the NAc core caused indiscriminate choice patterns. In contrast, NAc shell inactivation increased risky choice, more prominently on poor-odds trials. Additional experiments revealed that both subregions contribute to auditory conditional discrimination. NAc core or shell inactivation reduced Pavlovian approach elicited by an auditory CS+, yet shell inactivation also increased responding during presentation of a CS-. These data highlight distinct contributions for NAc subregions in decision making and reward seeking guided by discriminative stimuli. The core is crucial for implementation of conditional rules, whereas the shell refines reward seeking by mitigating the allure of larger, unlikely rewards and reducing expression of inappropriate or non-rewarded actions. SIGNIFICANCE STATEMENT Using external cues to guide decision making is crucial for adaptive behavior. Deficits in cue-guided behavior have been

  14. THE CONTRIBUTION OF PHILOSOPHY AND PSYCHOLOGY IN THE ETHICAL DECISION MAKING PROCESS

    2010-11-01

    Full Text Available This article aims to explore the relationship between morality and organizational culture with reference to the process of ethical decision making and to the cooperation between philosopher and psychologist for the improvement of ethical climate within a public institution. Firstly, we introduce the notion of organizational culture emphasizing the importance of moral values and their role in building a true ethical climate. Secondly, we focus on the study of ethical decision making. The process is examined from the perspective of the interaction between human personality and different elements of organizational culture. Philosophy and psychology differently approach this problem. Our intention is to bridge the gap between the two perspectives, by demonstrating their belonging to the same continuum as well as the need for knowledge from both fields in order to have a complete overview of its internal mechanisms. Deontological and utilitarian theories fail to explain by themselves the decision making process and so psychology does: moral development theories, the leadership type, and emotions have on their basis a personal moral philosophy. We will also consider the influence of social groups on individual decision making.

  15. IMPORTANCE OF DIFFERENT MODELS IN DECISION MAKING, EXPLAINING THE STRATEGIC BEHAVIOR IN ORGANIZATIONS

    Directory of Open Access Journals (Sweden)

    Cristiano de Oliveira Maciel

    2006-11-01

    Full Text Available This study is about the different models of decision process analyzing the organizational strategy. The article presents the strategy according to a cognitive approach. The discussion about that approach has three models of decision process: rational actor model, organizational behavior, and political model. These models, respectively, present some improvement in the decision making results, search for a good decision facing the cognitive restrictions of the administrator, and lots of talks for making a decision. According to the emphasis of each model, the possibilities for analyzing the strategy are presented. The article also shows that it is necessary to take into account the three different ways of analysis. That statement is justified once the analysis as well as the decision making become more complex, mainly those which are more important for the organizations.

    Speech-language pathologists' scope of practice is currently unclear in relation to their contribution to the multi-disciplinary assessment of decision-making capacity for clients with aphasia and related neurogenic communication disorders. The primary aim of the current research study was to investigate the common practices of speech-language pathologists involved in assessments of decision-making capacity. The study was completed through the use of an online survey. There were 51 of 59 respondents who indicated involvement in evaluations of decision-making. Involvement in this kind of assessment was most commonly reported by speech-language pathologists working in inpatient acute and rehabilitation settings. Respondents reported using a variety of formal and informal assessment methods in their contributions to capacity assessment. Discussion with multidisciplinary team members was reported to have the greatest influence on their recommendations. Speech-language pathologists reported that they were dissatisfied with current protocols for capacity assessments in their workplace and indicated they would benefit from further education and training in this area. The findings of this study are discussed in light of their implications for speech-language pathology practice.

    Reactive oxygen species (ROS) are generated spontaneously in all organisms and cause oxidative damage to biomolecules when present in excess. Accumulated oxidative damage accelerates aging; enhanced antioxidant capacity may be a positive factor for longevity. Recently, numerous studies of aging and longevity have been performed using short-lived animals, however, longevity mechanisms remain unknown. Here we show that a termite Reticulitermes speratus that is thought to be long-lived eusocial insect than other solitary insects uses large quantities of uric acid as an antioxidant against ROS. We demonstrated that the accumulation of uric acid considerably increases the free radical-scavenging activity and resistance against ultraviolet-induced oxidative stress in laboratory-maintained termites. In addition, we found that externally administered uric acid aided termite survival under highly oxidative conditions. The present data demonstrates that in addition to nutritional and metabolic roles, uric acid is an essential antioxidant for survival and contributes significantly to longevity. Uric acid also plays important roles in primates but causes gout when present in excess in humans. Further longevity studies of long-lived organisms may provide important breakthroughs with human health applications. PMID:28609463

  1. The Contribution of Fusion to Sustainable Development

    2006-01-01

    The world demand for energy is projected to more than double over the next 50 years, indeed this will be essential to bring much of the world out of poverty. At the same time there is increasing pressure to substantially reduce atmospheric pollution, most notably of carbon dioxide. Together, these conflicting goals drive a need to produce enormous amounts of non-carbon energy supply, much greater than our total present energy supply. This presents an enormous challenge. As one of very few options for large-scale, non-carbon future supply of energy, fusion has the potential to make an important contribution to sustained energy supplies. Fusion's advantages of large fuel reserves, low atmospheric emissions and high levels of safety make it an important consideration in future energy strategies. - Fuel supplies are sufficient for at least thousands of years, and probably up to millions of years, of energy use. - Atmospheric emissions of CO 2 are very low and minor emissions of other pollutants are less harmful than those from most existing energy sources. - Hazards to the public will be very low because of the high levels of passive safety. - Waste materials will require little, or no, use of repository storage. Conceptual designs of fusion power plants have been optimised against safety and environmental criteria. The optimum designs vary both with the assessed progress in the development programme and according to the weight given to different criteria. The impact of this weighting on design, and the comparison of the outcomes with other energy sources, is described. To make a contribution to sustainable development, fusion must also be economically viable to enter the energy market. The calculated cost of electricity from fusion and other technologies, both new and existing, show that, particularly in an energy market where environmental constraints are playing an increasing role, fusion can make an important contribution.

    This paper describes roles, extensions and applications of importance measures of components and configurations for making risk-informed decisions relevant to system operations, maintenance and safety. Basic importance measures and their relationships are described for independent and mutually exclusive events and for groups of events associated with common cause failures. The roles of importances are described mainly in two groups of activities: (a) ranking safety significance of systems, structures, components and human actions for preventive safety assurance activities, and (b) making decisions about permissible permanent and temporary configurations and allowed configuration times for regulation, technical specifications and for on-line risk monitoring. Criticality importance and sums of criticalities turn out to be appropriate measures for ranking and optimization. Several advantages are pointed out and consistent ranking of pipe segments for in-service inspection is provided as an example. Risk increase factor and its generalization risk gain are most appropriately used to assess corrective priorities and acceptability of a situation when components are already failed or when planning to take one or more components out of service for maintenance. Precise definitions are introduced for multi-failure configurations and it is shown how they can be assessed under uncertainties, in particular when common cause failures or success states may be involved. A general weighted average method is compared to other candidate methods in benchmark cases. It is the preferable method for prediction when a momentary configuration is known or only partially known. Potential applications and optimization of allowed outage times are described. The results show how to generalize and apply various importance measures to ranking and optimization and how to manage configurations in uncertain multi-failure situations. - Highlights: > Rigorous methods developed for using importances

    Assessment and appraisal of new medical technologies require a balance between the interests of different stakeholders. Final decision should take into account the societal value of new therapies. This perspective paper discusses the socio-economic burden of disease as a specific reimbursement decision-making criterion and calls for the inclusion of it as a counterbalance to the cost-effectiveness and budget impact criteria. Socio-economic burden is a decision-making criterion, accounting for diseases, for which the assessed medical technology is indicated. This indicator is usually researched through cost-of-illness studies that systematically quantify the socio-economic burden of diseases on the individual and on the society. This is a very important consideration as it illustrates direct budgetary consequences of diseases in the health system and indirect costs associated with patient or carer productivity losses. By measuring and comparing the socio-economic burden of different diseases to society, health authorities and payers could benefit in optimizing priority setting and resource allocation. New medical technologies, especially innovative therapies, present an excellent case study for the inclusion of socio-economic burden in reimbursement decision-making. Assessment and appraisal have been greatly concentrated so far on cost-effectiveness and budget impact, marginalizing all other considerations. In this context, data on disease burden and inclusion of explicit criterion of socio-economic burden in reimbursement decision-making may be highly beneficial. Realizing the magnitude of the lost socio-economic contribution resulting from diseases in question could be a reasonable way for policy makers to accept a higher valuation of innovative therapies.

    Decision-making theories explain animal behaviour, including human behaviour, as a response to estimations about the environment. In the case of collective behaviour, they have given quantitative predictions of how animals follow the majority option. However, they have so far failed to explain that in some species and contexts social cohesion increases when conditions become more adverse (i.e. individuals choose the majority option with higher probability when the estimated quality of all available options decreases). We have found that this failure is due to modelling simplifications that aided analysis, like low levels of stochasticity or the assumption that only one choice is the correct one. We provide a more general but simple geometric framework to describe optimal or suboptimal decisions in collectives that gives insight into three different mechanisms behind this effect. The three mechanisms have in common that the private information acts as a gain factor to social information: a decrease in the privately estimated quality of all available options increases the impact of social information, even when social information itself remains unchanged. This increase in the importance of social information makes it more likely that agents will follow the majority option. We show that these results quantitatively explain collective behaviour in fish and experiments of social influence in humans. © 2017 The Authors.

    Few studies have examined the contribution of different sub-regions of the prefrontal cortex and lesion laterality to decision-making abilities. In addition, there are inconsistent findings about the role of ventromedial and dorsolateral lesions in decision-making deficit. In this study, decision-making processes are investigated following different damaged areas of the prefrontal cortex. We paid particular attention to the contribution of laterality, lesion location and lesion volume in decision-making deficit. Twenty-seven patients with discrete ventromedial lesions, dorsolateral lesions or extended-frontal lesions were compared with normal subjects on the Iowa Gambling Task (IGT). Our results showed that all frontal subgroups were impaired on the IGT in comparison with normal subjects. We noted also that IGT performance did not vary systematically based on lesion laterality or location. More precisely, our lesion analysis revealed that decision-making processes depend on a large cerebral network, including both ventromedial and dorsolateral areas of the prefrontal cortex. Consistent with past findings, our results support the claim that IGT deficit is not solitarily associated with ventromedial prefrontal cortex lesions. Copyright © 2016 Elsevier Inc.

    Personal success often requires the choice to expend greater effort for larger rewards, and deficits in such effortful decision making accompany a number of illnesses including depression, schizophrenia, and attention-deficit/hyperactivity disorder. Animal models have implicated brain regions such as the basolateral amygdala (BLA) and anterior cingulate cortex (ACC) in physical effort-based choice, but disentangling the unique contributions of these two regions has proven difficult, and effort demands in industrialized society are predominantly cognitive in nature. Here we utilize the rodent cognitive effort task (rCET), a modification of the five-choice serial reaction-time task, wherein animals can choose to expend greater visuospatial attention to obtain larger sucrose rewards. Temporary inactivation (via baclofen-muscimol) of BLA and ACC showed dissociable effects: BLA inactivation caused hard-working rats to 'slack off' and 'slacker' rats to work harder, whereas ACC inactivation caused all animals to reduce willingness to expend mental effort. Furthermore, BLA inactivation increased the time needed to make choices, whereas ACC inactivation increased motor impulsivity. These data illuminate unique contributions of BLA and ACC to effort-based decision making, and imply overlapping yet distinct circuitry for cognitive vs physical effort. Our understanding of effortful decision making may therefore require expanding our models beyond purely physical costs.

    Brand, Paul L P; Stiggelbout, Anne M

    2013-12-01

    Paediatricians spend a considerable proportion of their time performing follow-up visits for children with chronic conditions, but they rarely receive specific training on how best to perform such consultations. The traditional method of running a follow-up consultation is based on the doctor's agenda, and is problem-oriented. Patients and parents, however, prefer a patient-centered, and solution-focused approach. Although many physicians now recognize the importance of addressing the patient's perspective in a follow-up consultation, a number of barriers hamper its implementation in practice, including time constraints, lack of appropriate training, and a strong tradition of the biomedical, doctor-centered approach. Addressing the patient's perspective successfully can be achieved through shared decision making, clinicians and patients making decisions together based on the best clinical evidence. Research shows that shared decision making not only increases patient, parent, and physician satisfaction with the consultation, but also may improve health outcomes. Shared decision making involves building a physician-patient-parent partnership, agreeing on the problem at hand, laying out the available options with their benefits and risks, eliciting the patient's views and preferences on these options, and agreeing on a course of action. Shared decision making requires specific communication skills, which can be learned, and should be mastered through deliberate practice. Copyright © 2013 Elsevier Ltd. All rights reserved.

  15. Making sense of the complex entanglement between emotion and pedagogy: contributions of the affective turn

    2016-09-01

    The purpose of this paper is to highlight three recent contributions of the affective turn: moving beyond the emotion/reason dichotomy; highlighting the politics of emotion and affect; and, strengthening the intersections of the psychic and the social. While these contributions are not necessarily paradigmatic of scholarship in the affective turn, they do highlight some important threads of thinking about affect theory in several fields of study, and thus they can be insightful in the context of science education as well. This discussion is motivated by the notion that science teaching and learning can benefit theoretically from these latest developments of affect theory. Although the question of why science teaching and learning has not paid so much attention to emotion and affect in the past is no less important, this paper will move past this in an effort to focus on the openings that are created for pedagogy in general.

    Stephens, Christine; Breheny, Mary

    2008-01-01

    Whether or not to use hormone replacement therapy (HRT) around the time of menopause is seen as an important decision for many mid-aged women. Recent studies of information provided to women to assist them in making a medical decision about the use of HRT have highlighted the importance of understanding the broader social context of the decision. In this article we examine one important aspect of western mid-aged women's social world: the moral order and the imperative of virtue. Qualitative data from a survey, focus group discussions, and interviews with mid-aged women about HRT use are used to provide examples of the importance of the local moral order in women's talk about menopause and HRT use. The implications of these data will be discussed in terms of the different narrative resources available to construct menopause and HRT, the role of morality, and the demonstration of virtue in daily social life, including medical decision making.

  17. Contributions of the life course perspective to research on food decision making.

    Wethington, Elaine; Johnson-Askew, Wendy L

    2009-12-01

    The life course perspective (LCP) has emerged as a powerful organizing framework for the study of health, illness, and mortality. LCP represents a "whole life" analysis perspective which originated in the field of sociology. Its concepts are increasingly applied to understanding the development of chronic disease over long periods of time in the human life span. A missing link, however, in the adaptation of the LCP to health research, is the insight the LCP may offer into understanding the societal, social network, and family contexts that frame stability and change in dietary behavior. This paper reviews key concepts that comprise the LCP but primarily focuses on applications that have relevance to food decision making in social context.

    Technical and Vocational Education and Training (TVET) has been gaining its popularity and considered as the driving force for sustainable development. TVET is also considered highly in strategic and operational priorities of the G20, the Organisation for Economic Co-operation and Development (OECD), and of multilateral organizations such as the International Labour Organization (ILO), UNESCO, ASEAN, and SEAMEO. As reflected in Shanghai Consensus, TVET systems need sustained transformation and revitalization if TVET is to realize its enormous potential to impact development. This paper will elaborate relevant policies considered as major drivers for promoting TVET at global, regional, and national levels. The paper also shares TVET initiatives in response the policies, especially in meeting the labour market demands in the 21st century. Lastly, the paper highlights TVET contribution to sustainable development, particularly on the sustainable environmental development, including green jobs. The integration of sustainable development into TVET curriculum, learning contents, and also school policies and practices are important indicators to consider. The paper was based secondary data and documents from the meetings and also reports.

    Most patients (70%) want to participate actively in important healthcare decisions, the rest (30%) prefer the doctor to make the decision for them. Shared decision-making provides more patient satisfaction, a better quality of life and contributes to a better doctor-patient relationship. Patients making their own decision generally make a well considered and medically sensible choice. In shared decision-making the doctor asks many open questions, gives and requests much information, asks if the patient wishes to participate in the decision-making and explicitly takes into account patient circumstances and preferences. Shared decision-making should remain an individual choice and should not become a new dogma.

    2017-06-01

    The debate around value in oncology drug selection has been prominent in recent years, and several professional bodies have furthered this debate by advocating for so-called value frameworks. Herein, we provide a viewpoint on these value frameworks, emphasizing the need to consider 4 key aspects: (1) the economic underpinnings of value; (2) the importance of the perspective adopted in the valuation; (3) the importance of the difference between absolute and relative measures of risk and measuring patient preferences; and (4) the recognition of multiple quality-of-life (QoL) domains, and the aggregation and valuation of those domains, through utilities within a multicriteria decision analysis, may allow prioritization of QoL above the tallying of safety events, particularly in a value framework focusing on the individual patient. While several frameworks exist, they incorporate different attributes and-importantly-assess value from alternative perspectives, including those of patients, regulators, payers, and society. The various perspectives necessarily lead to potentially different, if not sometimes divergent, conclusions about the valuation. We show that the perspective of the valuation affects the framing of the risk/benefit question and the methodology to measure the individual patient choice, or preference, as opposed to the collective, or population, choice. We focus specifically on the American Society of Clinical Oncology (ASCO) Value Framework. We argue that its laudable intent to assist in shared clinician-patient decision making can be augmented by more formally adopting methodology underpinned by micro- and health economic concepts, as well as application of formal quantitative approaches. Our recommendations for value frameworks focusing on the individual patient, such as the ASCO Value Framework, are 3-fold: (1) ensure that stakeholders understand the importance of the adopted (economic) perspective; (2) consider using exclusively absolute measures of

    NASA Worldview is an interactive interface for browsing full-resolution, global satellite imagery. Worldview supports an open data policy so that academia, private industries and the general public can use NASA's satellite data to address Earth science related issues. Worldview was open sourced in 2014. By shifting to an open source approach, the Worldview application has evolved to better serve end-users. Project developers are able to have discussions with end-users and community developers to understand issues and develop new features. Community developers are able to track upcoming features, collaborate on them and make their own contributions. Developers who discover issues are able to address those issues and submit a fix. This reduces the time it takes for a project developer to reproduce an issue or develop a new feature. Getting new developers to contribute to the project has been one of the most important and difficult aspects of open sourcing Worldview. After witnessing potential outside contributors struggle, a focus has been made on making the installation of Worldview simple to reduce the initial learning curve and make contributing code easy. One way we have addressed this is through a simplified setup process. Our setup documentation includes a set of prerequisites and a set of straightforward commands to clone, configure, install and run. This presentation will emphasize our focus to simplify and standardize Worldview's open source code so that more people are able to contribute. The more people who contribute, the better the application will become over time.

    Johnson-Askew, Wendy L.

    2012-01-01

    Background The life course perspective (LCP) has emerged as a powerful organizing framework for the study of health, illness, and mortality. LCP represents a “whole life” analysis perspective which originated in the field of sociology. Methods Its concepts are increasingly applied to understanding the development of chronic disease over long periods of time in the human life span. A missing link, however, in the adaptation of the LCP to health research, is the insight the LCP may offer into understanding the societal, social network, and family contexts that frame stability and change in dietary behavior. Results This paper reviews key concepts that comprise the LCP but primarily focuses on applications that have relevance to food decision making in social context. A case study of chronic work–family stress and perceived time scarcity as barriers to dietary improvement is included. Conclusion Illustrative findings are presented on dietary behavior in a diverse sample of lower-income working parents. This paper also offers ideas on increasing the contributions of the LCP to nutritional research. PMID:19890684

    The importance of decision-making to safety in complex, dynamic environments like mission control centers and offshore installations has been well established. NASA-ARC has a program of research dedicated to fostering safe and effective decision-making in the manned spaceflight environment. Because access to spaceflight is limited, environments with similar characteristics, including aviation and nuclear power plants, serve as analogs from which space-relevant data can be gathered and theories developed. Analyses of aviation accidents cite crew judgement and decision making as causes or contributing factors in over half of all accidents. A similar observation has been made in nuclear power plants. Yet laboratory research on decision making has not proven especially helpful in improving the quality of decisions in these kinds of environments. One reason is that the traditional, analytic decision models are inappropriate to multidimensional, high-risk environments, and do not accurately describe what expert human decision makers do when they make decisions that have consequences. A new model of dynamic, naturalistic decision making is offered that may prove useful for improving decision making in complex, isolated, confined and high-risk environments. Based on analyses of crew performance in full-mission simulators and accident reports, features that define effective decision strategies in abnormal or emergency situations have been identified. These include accurate situation assessment (including time and risk assessment), appreciation of the complexity of the problem, sensitivity to constraints on the decision, timeliness of the response, and use of adequate information. More effective crews also manage their workload to provide themselves with time and resources to make good decisions. In brief, good decisions are appropriate to the demands of the situation. Effective crew decision making and overall performance are mediated by crew communication. Communication

    2016-04-01

    When making health care decisions, patients and consumers use data but also gather stories from family and friends. When advising patients, clinicians consult the medical evidence but also use professional judgment. These stories and judgments, as well as other forms of narrative, shape decision making but remain poorly understood. Furthermore, qualitative research methods to examine narrative are rarely included in health science research. We illustrate how narratives shape decision making and explain why it is difficult but necessary to integrate qualitative research on narrative into the health sciences. We draw on social-scientific insights on rigorous qualitative research and our ongoing studies of decision making by patients with cancer, and we describe new tools and approaches that link qualitative research findings with the predominantly quantitative health science scholarship. Finally, we highlight the benefits of more fully integrating qualitative research and narrative analysis into the medical evidence base and into evidence-based medical practice.

    Full Text Available This research aims to demonstrate how portfolio management influences the decision-making process in the projects of a financial organization. And to achieve this goal was used the single case study method. In order to reach this goal, the study began by means of bibliometric research on the subject of portfolio management and subsequent bibliographic research on the theme, decision making. Next, the relationships between portfolio management and decision making were studied. The results of the data collected confirmed the relationship between "the use of the project identification process in portfolio management to influence decision making" in order to add value to the business. It is also possible to demonstrate moderately that "the use of criteria for project selection influences the consequences of decision making", helping in the strategic management of the organization. One of the academic contributions was to note a migration of the portfolio management process, such as a tool that only controls the projects that will compose the portfolio of an organization, for a process that aims at a direct alignment with the strategic management of the organization. Regarding the practical implications, it was verified the importance of portfolio analysis for decision making, to the detriment of the evaluation of only one project. Taking into account the profitability and the return on investment of the projects, as the most important aspects for a decision making.

    In the long term, the sector coupling will convert other areas of consumption such as heat and transport to purely renewable energy sources. A model-based analysis of system costs across all stages of the value chain shows that the existing gas infrastructure in particular can make an important contribution to achieving a comprehensive energy turnaround at low cost. Preserving the gas networks in connection with the use of green gas as a further end energy carrier in addition to electricity leads to significantly lower overall costs than a comprehensive electrification of all end applications. This can also help overcome acceptance problems. [German] Mit der Sektorkopplung werden langfristig weitere Verbrauchsbereiche wie Waerme und Verkehr auf rein erneuerbare Energiequellen umgestellt.

    In the middle of the 20th century two Chinese women physicists, Ming-Chen Wang and Cheng-Shu Wang Chang made great contributions to statistical physics. The famous review article 'On the theory of the Brownian motion II' by Ming-Chen Wang and G.E. Uhlenbeck published in Rev. of Mod. Phys. in 1945 provided a complete scientific classification of stochastic processes which is still adopted by the scientific community as the standard classification. The Wang-Chang-Uhlenbeck (WCU) equation proposed jointly by C.S. Wang-Chang and Uhlenbeck became the fundamental kinetic equation for the treatment of transport properties of multi-atomic gases with internal degrees of freedom in the physics literature. These important scientific contributions are analyzed and reviewed

    The National Lung Screening Trial recently reported that annual low-dose computed tomography screening is associated with decreased lung cancer mortality in high-risk smokers. This study sought to identify the factors patients consider important in making lung cancer screening (LCS) decisions, and explore variations by patient characteristics and LCS participation. This observational survey study evaluated the Minneapolis VA LCS Clinical Demonstration Project in which LCS-eligible Veterans (N=1388) were randomized to either Direct LCS Invitation (mailed with decision aid, N=926) or Usual Care (provider referral, N=462). We surveyed participants three months post-randomization (response rate 44%) and report the proportion of respondents rating eight decision-making factors (benefits, harms, and neutral factors) as important by condition, patient characteristics, and LCS completion. Overall, the most important factor was personal risk of lung cancer and the least important factor was health risks from LCS. The reported importance varied by patient characteristics, including smoking status, health status, and education level. Overall, the potential harms of LCS were reported less important than the benefits or the neutral decision-making factors. Exposure to Direct LCS Invitation (with decision aid) increased Veterans' attention to specific decision-making factors; compared to Usual Care respondents, a larger proportion of Direct LCS Invitation respondents rated the chance of false-positive results, LCS knowledge, LCS convenience, and anxiety as important. Those completing LCS considered screening harms less important, with the exception of incidental findings. Decision tools influence Veterans' perceptions about LCS decision-making factors. As the factors important to LCS decision making vary by patient characteristics, targeted materials for specific subgroups may be warranted. Attention should be paid to how LCS incidental findings are communicated. Published by

    A closer look at the lived illness experiences of medical professionals themselves shows that shared decision making is in need of a logic of care. This paper underlines that medical decision making inevitably takes place in a messy and uncertain context in which sharing responsibilities may impose a considerable burden on patients. A better understanding of patients' lived experiences enables healthcare professionals to attune to what individual patients deem important in their lives.This will contribute to making medical decisions in a good and caring manner, taking into account the lived experience of being ill.

    Decision making in the context of risk is a complex and dynamic process that changes across development. Here, we assessed the influence of sensitivity to negative feedback (e.g., loss) and learning on age-related changes in risky decision making, both of which show unique developmental trajectories. In the present study, we examined risky decision making in 216 individuals, ranging in age from 3-26 years, using the balloon emotional learning task (BELT), a computerized task in which participants pump up a series of virtual balloons to earn points, but risk balloon explosion on each trial, which results in no points. It is important to note that there were 3 balloon conditions, signified by different balloon colors, ranging from quick- to slow-to-explode, and participants could learn the color-condition pairings through task experience. Overall, we found age-related increases in pumps made and points earned. However, in the quick-to-explode condition, there was a nonlinear adolescent peak for points earned. Follow-up analyses indicated that this adolescent phenotype occurred at the developmental intersection of linear age-related increases in learning and decreases in sensitivity to negative feedback. Adolescence was marked by intermediate values on both these processes. These findings show that a combination of linearly changing processes can result in nonlinear changes in risky decision making, the adolescent-specific nature of which is associated with developmental improvements in learning and reduced sensitivity to negative feedback.

    Earth observations are playing an increasingly significant role in informing decision making in the energy sector. In renewable energy applications, space-based observations now routinely augment sparse ground-based observations used as input for renewable energy resource assessment applications. As one of the nine Group on Earth Observations (GEO) societal benefit areas, the enhancement of management and policy decision making in the energy sector is receiving attention in activities conducted by the Committee on Earth Observation Satellites (CEOS). CEOS has become the “space arm” for the implementation of the Global Earth Observation System of Systems (GEOSS) vision. It is directly supporting the space-based, near-term tasks articulated in the GEO three-year work plan. This paper describes a coordinated program of demonstration projects conducted by CEOS member agencies and partners to utilize Earth observations to enhance energy management end-user decision support systems. We discuss the importance of engagement with stakeholders and understanding their decision support needs in successfully increasing the uptake of Earth observation products for societal benefit. Several case studies are presented, demonstrating the importance of providing data sets in formats and units familiar and immediately usable by decision makers. These projects show the utility of Earth observations to enhance renewable energy resource assessment in the developing world, forecast space weather impacts on the power grid, and improve energy efficiency in the built environment.

    The use of risk-based decision-making in environmental management is often assumed to rely primarily on the availability of robust scientific data and insights, while in practice socio-economic criteria are often of considerable importance. However, the relative contributions to decision-making made by scientific and socio-economic inputs are rarely assessed, and even less commonly reported. Such an assessment has been made for a major remediation project in southwest England, in which some 300 l/s of highly acidic, metalliferous mine waters are now being treated using oxidation and chemical neutralisation. In the process of reaching the decision to commission the treatment plant, a wide range of scientific studies were undertaken, including: biological impact assessments, hydrogeological investigations of the effect of pumping on the flooded mine system, and hydrological and geochemical characterisation, together with integrated catchment modelling, of pollutant sources and pathways. These investigations revealed that, despite the spectacular nature of the original mine water outburst in 1992, the ecology of the Fal estuary remains remarkably robust. No scientific evidence emerged of any grounds for concern over the estuarine ecology, even if mine water were left to flow untreated. However, a rare ecological resource known as "maerl" (a form of calcified seaweed) is harvested annually in the estuary, providing significant revenue to the local economy and underpinning the 'clean' image of local sea water. Social and environmental benefit surveys revealed strong public perceptions that any visible discoloration in the estuary must indicate a diminution in quality of the maerl, to the detriment of both the public image and economy of the area. This factor proved sufficient to justify the continued pump-and-treat operations at the mine site. Although the decisive factor in the end was socio-economic in nature, robust assessment of this factor could not have been made

  7. The amygdala and decision-making.

    2011-03-01

    Decision-making is a complex process that requires the orchestration of multiple neural systems. For example, decision-making is believed to involve areas of the brain involved in emotion (e.g., amygdala, ventromedial prefrontal cortex) and memory (e.g., hippocampus, dorsolateral prefrontal cortex). In this article, we will present findings related to the amygdala's role in decision-making, and differentiate the contributions of the amygdala from those of other structurally and functionally connected neural regions. Decades of research have shown that the amygdala is involved in associating a stimulus with its emotional value. This tradition has been extended in newer work, which has shown that the amygdala is especially important for decision-making, by triggering autonomic responses to emotional stimuli, including monetary reward and punishment. Patients with amygdala damage lack these autonomic responses to reward and punishment, and consequently, cannot utilize "somatic marker" type cues to guide future decision-making. Studies using laboratory decision-making tests have found deficient decision-making in patients with bilateral amygdala damage, which resembles their real-world difficulties with decision-making. Additionally, we have found evidence for an interaction between sex and laterality of amygdala functioning, such that unilateral damage to the right amygdala results in greater deficits in decision-making and social behavior in men, while left amygdala damage seems to be more detrimental for women. We have posited that the amygdala is part of an "impulsive," habit type system that triggers emotional responses to immediate outcomes. Copyright © 2010 Elsevier Ltd. All rights reserved.

    2017-04-01

    To outline and detail the importance of conditional probability in clinical decision making and discuss the various diagnostic measures eye care practitioners should be aware of in order to improve the scope of their clinical practice. We conducted a review of the importance of conditional probability in diagnostic testing for the eye care practitioner. Eye care practitioners use diagnostic tests on a daily basis to assist in clinical decision making and optimizing patient care and management. These tests provide probabilistic information that can enable the clinician to increase (or decrease) their level of certainty about the presence of a particular condition. While an understanding of the characteristics of diagnostic tests are essential to facilitate proper interpretation of test results and disease risk, many practitioners either confuse or misinterpret these measures. In the interests of their patients, practitioners should be aware of the basic concepts associated with diagnostic testing and the simple mathematical rule that underpins them. Importantly, the practitioner needs to recognize that the prevalence of a disease in the population greatly determines the clinical value of a diagnostic test.

These two psychologies are different, but they can make important reciprocals contributions. And the best of the intuitive psychology, that in my opinion is in the literature and overall in the romance, can be very useful for professional psychologists. The main end of this paper is to show how the social psychologists can learn from the intuitive psychology of the great romances. This contribution of the romance to the social psychology is, at least, at these two levels. At the level of construction of the subjectivity and the modern subject and the, therefore, of the psychology’s arise, and at the level of some concrete subjects studied by the psychologists (romantic love, jealousy, infidelity, compunction, emotions, vengeance, human relations…

    2015-01-01

    In this study it was sought to quantify post-stocking growth, survival, and contribution of advanced size (178 mm total length [TL]) channel catfish Ictalurus punctatus fingerlings, something rarely done. Channel catfish populations were evaluated before (May 2010) and after (May to August 2011 and 2012) stocking. Relative abundance, stocking contribution, and growth were different (P stocked in Lake Lone Chimney, stocking contribution was lower (3–35%), and average length and weight of stocked fish by age-2 reached 230 mm TL and 85 g, whereas the stocking contribution (84–98%) and growth in length (340 mm TL) and weight (280 g) were higher by age-2 in Lake Greenleaf. Given these unambiguous differences of post-stocking performance, benchmark metrics that represent population-level information such as relative abundance and average length and weight of the sample masked these significant differences, highlighting the importance of marking hatchery-fish and then following them through time to determine the effectiveness of stocking. These results suggest that stock enhancement programmes would benefit from studies that quantify post-stocking performance of hatchery fish.

    Though reported capture fisheries are dominated by marine production, inland fish and fisheries make substantial contributions to meeting the challenges faced by individuals, society, and the environment in a changing global landscape. Inland capture fisheries and aquaculture contribute over 40% to the world’s reported finfish production from less than 0.01% of the total volume of water on earth. These fisheries provide food for billions and livelihoods for millions of people worldwide. Herein, using supporting evidence from the literature, we review 10 reasons why inland fish and fisheries are important to the individual (food security, economic security, empowerment), to society (cultural services, recreational services, human health and well-being, knowledge transfer and capacity building), and to the environment (ecosystem function and biodiversity, as aquatic “canaries”, the “green food” movement). However, the current limitations to valuing the services provided by inland fish and fisheries make comparison with other water resource users extremely difficult. This list can serve to demonstrate the importance of inland fish and fisheries, a necessary first step to better incorporating them into agriculture, land-use, and water resource planning, where they are currently often underappreciated or ignored.

    Full Text Available Organizations are operating in a dynamic and turbulent environment. In these conditions, they have to make decisions for new problems or situations. Most of decisions are therefore non-programmed and unstructured, accompanied by risk and uncertainty. Moreover, the problems and situations are complex. All organizations are oriented towards group decisionmaking processes, as useful tools to cope with uncertainty and complexity. Apart from the necessity, companies are turning towards participatory processes also to benefit from the important advantages that these processes offer. Organizations have realized the importance of group decision-making processes to contribute to the creation of sustainable competitive advantages. Main objective of this paper is to show that group decision-making processes do not offer guarantee for good decisions, because the effectiveness of group is affected by many factors. So, the first thing done in this paper is discussing about the benefits and limitations that accompany the use of groups with decision-making purpose. Afterwards, we stop on the different factors that influence the group’s ability to make good decisions. The aim is to emphasize that regardless of the many advantages of groups, some factors as group size, type of communication within the group, leadership style, the norms, the differentiation of roles and statuses, cohesion and compliance degree should be the main elements to keep into consideration because they affect the effectiveness of group. In this regard, is discussed how such factors influence the quality of decision and then we try to draw some conclusions that can improve and make better and easier group decision-making processes.

    2013-01-01

    The book provides a comprehensive and timely report on the topic of decision making and decision analysis in economics and the social sciences. The various contributions included in the book, selected using a peer review process, present important studies and research conducted in various countries around the globe. The majority of these studies are concerned with the analysis, modeling and formalization of the behavior of groups or committees that are in charge of making decisions of social and economic importance. Decisions in these contexts have to meet precise coherence standards and achieve a significant degree of sharing, consensus and acceptance, even in uncertain and fuzzy environments. This necessitates the confluence of several research fields, such as foundations of social choice and decision making, mathematics, complexity, psychology, sociology and economics. A large spectrum of problems that may be encountered during decision making and decision analysis in the areas of economics and the social ...

    The contribution of patients' non-medical characteristics to individual physicians' decision-making has attracted considerable attention, but little information is available on this topic in the context of collective decision-making. Medical decision-making at cancer centres is currently carried out using a collective approach, at MultiDisciplinary Team (MDT) meetings. The aim of this study was to determine how patients' non-medical characteristics are presented at MDT meetings and how this information may affect the team's final medical decisions. Observations were conducted at a French Cancer Centre during MDT meetings at which non-standard cases involving some uncertainty were discussed from March to May 2014. Physicians' verbal statements and predefined contextual parameters were collected with a non-participant observational approach. Non numerical data collected in the form of open notes were then coded for quantitative analysis. Univariate and multivariate statistical analyses were performed. In the final sample of patients' records included and discussed (N = 290), non-medical characteristics were mentioned in 32.8% (n = 95) of the cases. These characteristics corresponded to demographics in 22.8% (n = 66) of the cases, psychological data in 11.7% (n = 34), and relational data in 6.2% (n = 18). The patient's age and his/her "likeability" were the most frequently mentioned characteristics. In 17.9% of the cases discussed, the final decision was deferred: this outcome was positively associated with the patients' non-medical characteristics and with uncertainty about the outcome of the therapeutic options available. The design of the study made it difficult to draw definite cause-and-effect conclusions. The Social Representations approach suggests that patients' non-medical characteristics constitute a kind of tacit professional knowledge that may be frequently mobilised in physicians' everyday professional practice. The links observed between patients

    2005-01-01

    Critical examination of the processes by which we as nurses judge and reach clinical decisions is important. It facilitates the maintenance and refinement of good standards of nursing care and the pinpointing of areas where improvement is needed. In turn this potentially could support broader validation of nurse expertise and contribute to emancipation of the nursing profession. As pure theory, clinical decision-making may appear abstract and alien to nurses struggling in 'the swampy lowlands' (Schon 1983) of the realities of practice. This paper explores some of the key concepts in decision-making theory by introducing, then integrating, them in a reflective case study. The case study, which examines a 'snapshot' of the patient and practitioner's journey, interwoven with theory surrounding clinical decision-making, may aid understanding and utility of concepts and theories in practice.

    In view of the negative impact of functional dependency, this paper attempts to provide an alternative importance measure called Improved-PageRank (IPR) for measuring the importance of components in mechatronics systems. IPR is a meaningful extension of the centrality measures in complex network, which considers usage reliability of components and functional dependency between components to increase importance measures usefulness. Our work makes two important contributions. First, this paper integrates the literature of mechatronic architecture and complex networks theory to define component network. Second, based on the notion of component network, a meaningful IPR is brought into the identifying of important components. In addition, the IPR component importance measures, and an algorithm to perform stochastic ordering of components due to the time-varying nature of usage reliability of components and functional dependency between components, are illustrated with a component network of bogie system that consists of 27 components.

    Full Text Available In modern conditions of operation, the provision of right information to customers is one of the key factors of marketing communication success. When making the decision on the selection of travel, customers in tourism (tourists have the need for greater number of different information compared to the selection of other products and services. The need for more information is conditioned by the specificity of travel as a product. The tourists gather different information in the travel decision-making process on destinations, activities at destinations, hotels and services they offer, travel programs, etc. Likewise, the information on the brand and image of tourist destination they are travelling to and the brand of tourist service provider (hotel, tour-operator, travel agency, etc. are also relevant. Brands present a kind of quality guarantee and reduce the need for additional information. The aim of this paper is to determine the significance of different information for various segments of customers in tourism on the basis of empirical research. The paper will test whether various tourist segments, towards which the different communication strategies focused on travel promotion would be formulated, can be identified based on the type of information the tourists gather in the decision-making process. The paper will also consider whether the segmentation of the tourism market, based on the relevance of different information in the decision-making process of tourists, is more efficient compared to the segmentation based on the traditional criteria.

    Full Text Available Today, we see a busy and fast period of change in all area of our life. This process consistently changes especially the management domain and forces business managers to be ready to change at any moment. Change has become so fast all around the world and it has turned into a multidimensional concept. The period of change in which we live in an interactive and fast way in political, social, cultural and economic areas brings up different processes such as quick start, quick decision making, bringing more dynamics and flexibility structure to management. In this context, the main idea of our study is based on that businesses should manage the process of change by using strategies. Businesses which understand clearly what strategy is and design their future plans based on those strategies are going to be more successful than their competitors in the environments seen fierce competition and fast change. In our study formed around this basic thesis, first we will make a conceptual analysis related to strategies, then refer to the importance of strategic management and we will examine strategic management contributions to businesses and finally, we will mention the importance of connection between strategy and culture of an organization to be enable more success in the strategic management process.

    2013-01-01

    Full Text Available Many studies have been conducted on the application of reinforcement learning (RL to robots. A robot which is made for general purpose has redundant sensors or actuators because it is difficult to assume an environment that the robot will face and a task that the robot must execute. In this case, -space on RL contains redundancy so that the robot must take much time to learn a given task. In this study, we focus on the importance of sensors with regard to a robot’s performance of a particular task. The sensors that are applicable to a task differ according to the task. By using the importance of the sensors, we try to adjust the state number of the sensors and to reduce the size of -space. In this paper, we define the measure of importance of a sensor for a task with the correlation between the value of each sensor and reward. A robot calculates the importance of the sensors and makes the size of -space smaller. We propose the method which reduces learning space and construct the learning system by putting it in RL. In this paper, we confirm the effectiveness of our proposed system with an experimental robot.

    2016-01-01

    Summary Reinforcement learning (RL) theories posit that dopaminergic signals are integrated within the striatum to associate choices with outcomes. Often overlooked is that the amygdala also receives dopaminergic input and is involved in Pavlovian processes that influence choice behavior. To determine the relative contributions of the ventral striatum (VS) and amygdala to appetitive RL we tested rhesus macaques with VS or amygdala lesions on deterministic and stochastic versions of a two-arm bandit reversal learning task. When learning was characterized with a RL model relative to controls, amygdala lesions caused general decreases in learning from positive feedback and choice consistency. By comparison, VS lesions only affected learning in the stochastic task. Moreover, the VS lesions hastened the monkeys’ choice reaction times, which emphasized a speed-accuracy tradeoff that accounted for errors in deterministic learning. These results update standard accounts of RL by emphasizing distinct contributions of the amygdala and VS to RL. PMID:27720488

    2011-01-01

    Rufus of Ephesus, a famous ancient physician, lived about the years 80 - 150 CE. His theories stressed the importance of anatomy and he preferred pragmatic approach to diagnosis and treatment. In his work "On the Names of the Parts of the Human Body", he put in pragmatic effort to make a lexicon of anatomy for his pupils. In the introduction, he described it as a manual for the students of medical art which relied on demonstration in teaching; visible (outer) parts of the body were shown on a demonstrator and invisible (inner) parts were shown on a dissected monkey. The brief explanation of the anatomical terms includes position, shape, and functions of organs, and this is what makes his work a pioneering effort to explain the anatomy clearly, systematically, and using consistent terminology. Rufus stressed the importance of exact nomenclature to prevent misunderstandings in medical practice. This anatomy manual had a major influence on the development of anatomical terminology. It is an important contribution to the history of teaching. The other essential contribution of Rufus' lexicon (also known for its briefer title Onomastikon) is that the author recognised and critically reviewed the knowledge and views of his predecessors, physicians of the pre-Galenic period. No less important was his teaching to anatomists and physicians who followed, as they often cited or paraphrased Rufus in their own works (Galen, Oribasius). Many fragments of Rufus' work have been preserved by medieval Arabic medical writers, especially by Rhazes.

    Full Text Available Launching a new business or project leads managers to make decisions and choose strategies that will then apply in their company. Most often, they take decisions only on instinct, but there are also companies that use benchmarking studies. Benchmarking is a highly effective management tool and is useful in the new competitive environment that has emerged from the need of organizations to constantly improve their performance in order to be competitive. Using this benchmarking process, organizations try to find the best practices applied in a business, learn from famous leaders and identify ways to increase their performance and competitiveness. Thus, managers gather information about market trends and about competitors, especially about the leaders in the field, and use these information in finding ideas and setting of guidelines for development. Benchmarking studies are often used in businesses of commerce, real estate, and industry and high-tech software.

  17. A Molecular Staple: D-Loops in the I Domain of Bacteriophage P22 Coat Protein Make Important Intercapsomer Contacts Required for Procapsid Assembly

    Science.gov (United States)

    D'Lima, Nadia G.

    2015-01-01

    ABSTRACT Bacteriophage P22, a double-stranded DNA (dsDNA) virus, has a nonconserved 124-amino-acid accessory domain inserted into its coat protein, which has the canonical HK97 protein fold. This I domain is involved in virus capsid size determination and stability, as well as protein folding. The nuclear magnetic resonance (NMR) solution structure of the I domain revealed the presence of a D-loop, which was hypothesized to make important intersubunit contacts between coat proteins in adjacent capsomers. Here we show that amino acid substitutions of residues near the tip of the D-loop result in aberrant assembly products, including tubes and broken particles, highlighting the significance of the D-loops in proper procapsid assembly. Using disulfide cross-linking, we showed that the tips of the D-loops are positioned directly across from each other both in the procapsid and the mature virion, suggesting their importance in both states. Our results indicate that D-loop interactions act as “molecular staples” at the icosahedral 2-fold symmetry axis and significantly contribute to stabilizing the P22 capsid for DNA packaging. IMPORTANCE Many dsDNA viruses have morphogenic pathways utilizing an intermediate capsid, known as a procapsid. These procapsids are assembled from a coat protein having the HK97 fold in a reaction driven by scaffolding proteins or delta domains. Maturation of the capsid occurs during DNA packaging. Bacteriophage HK97 uniquely stabilizes its capsid during maturation by intercapsomer cross-linking, but most virus capsids are stabilized by alternate means. Here we show that the I domain that is inserted into the coat protein of bacteriophage P22 is important in the process of proper procapsid assembly. Specifically, the I domain allows for stabilizing interactions across the capsid 2-fold axis of symmetry via a D-loop. When amino acid residues at the tip of the D-loop are mutated, aberrant assembly products, including tubes, are formed instead

    2016-09-01

    The spread of influential misinformation, such as conspiracy theories about the existence of a secret, large-scale atmospheric spraying program (SLAP), is contributing to the politicization of science. In an important recent study, Shearer et al (2016 Environ. Res. Lett. 11 084011) employ a novel methodology to quantify the expert consensus of popular SLAP assertions. The authors find that 99% (76/77) of surveyed experts have not encountered any evidence that would support the existence of such a program. Here we argue that this finding is important because a growing body of research has shown that the public’s perception of expert consensus on key societal issues acts an important ‘gateway’ to science acceptance. Furthermore, communicating normative agreement among experts, such as the strong scientific consensus against the existence of a SLAP, can help limit the spread of misinformation and promote more effective public decision-making about science and society.

    The importance of decision-making to safety in complex, dynamic environments like mission control centers and offshore installations has been well established. NASA-ARC has a program of research dedicated to fostering safe and effective decision-making in the manned spaceflight environment. Because access to spaceflight is limited, environments with similar characteristics, including aviation and nuclear power plants, serve as analogs from which space-relevant data can be gathered and theories developed. Analyses of aviation accidents cite crew judgement and decision making as causes or contributing factors in over half of all accidents. A similar observation has been made in nuclear power plants. Yet laboratory research on decision making has not proven especially helpful in improving the quality of decisions in these kinds of environments. One reason is that the traditional, analytic decision models are inappropriate to multidimensional, high-risk environments, and do not accurately describe what expert human decision makers do when they make decisions that have consequences. A new model of dynamic, naturalistic decision making is offered that may prove useful for improving decision making in complex, isolated, confined and high-risk environments. Based on analyses of crew performance in full-mission simulators and accident reports, features that define effective decision strategies in abnormal or emergency situations have been identified. These include accurate situation assessment (including time and risk assessment), appreciation of the complexity of the problem, sensitivity to constraints on the decision, timeliness of the response, and use of adequate information. More effective crews also manage their workload to provide themselves with time and resources to make good decisions. In brief, good decisions are appropriate to the demands of the situation. Effective crew decision making and overall performance are mediated by crew communication. Communication

    In this study, we investigated what makes a symptom or functional impairment clinically important, that is, relevant for a patient to discuss with a health care professional (HCP). This is the first part of a European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group project focusing on the development of thresholds for clinical importance for the EORTC QLQ-C30 questionnaire and its corresponding computer-adaptive version. We conducted interviews with cancer patients and HCPs in 6 European countries. Participants were asked to name aspects of a symptom or problem that make it clinically important and to provide importance ratings for a predefined set of aspects (eg, need for help and limitations of daily functioning). We conducted interviews with 83 cancer patients (mean age, 60.3 y; 50.6% men) and 67 HCPs. Participants related clinical importance to limitations of everyday life (patients, 65.1%; HCPs, 77.6%), the emotional impact of a symptom/problem (patients, 53.0%; HCPs, 64.2%), and duration/frequency (patients, 51.8%; HCPs, 49.3%). In the patient sample, importance ratings were highest for worries by partner or family, limitations in everyday life, and need for help from the medical staff. Health care professionals rated limitations in everyday life and need for help from the medical staff to be most important. Limitations in everyday life, need for (medical) help, and emotional impact on the patient or family/partner were found to be relevant aspects of clinical importance. Based on these findings, we will define anchor items for the development of thresholds for clinical importance for the EORTC measures in a Europe-wide field study.

    ENGLISH ABSTRACT: This study has been carried out to discover the impact of the product life cycle (PLC on the importance of outsourcing decision-making criteria in a manufacturing firm. The four dimensions of outsourcing decision-making were identified, based on a literature review and on the conditions of the firm: (1 core competencies, (2 information leakage risk, (3 technological capability, and (4 cost. A case study and survey research were used, along with two non-parametric tests (Friedman’s test and Kendall’s W. The results show in particular that the importance of ‘technological capability’ and ‘strategic information leakage risk’ does not differ across the various PLC stages. The importance of ‘leakage risk of product volume information’ and ‘total cost’ change over different stages of the product life cycle are also addressed. For the latter two criteria, the probabilities of each rating related to each criterion importance have been estimated by ordinal logistic regression, and the weights of these criteria have been calculated at each stage of the product life cycle.

  3. Concepts on the contribution of chemistry to a sustainable development. Renewable raw materials

    2004-01-01

    The principles of the Rio Conference (1992) and Agenda 21 address the pressing problems of today and also aim at preparing the world for the challenges of this century. The conservation and management of resources for development are the main foci of interest, to which chemistry will have to make a considerable contribution. Since base chemicals are produced in large quantities and important product lines are synthesized from them, their resource-saving production is especially important for a sustainable development. New processes based on renewable feedstocks are significant here. Most products that are obtained from renewable raw materials may, at present, not be able to compete with the products of the petrochemical industry, but this will change as oil becomes scarcer and oil prices rise. The design of chemical products should make sustainable processing and recycling possible, and should prevent their bioaccumulation. Methods and criteria to assess their contribution to a sustainable development are necessary. The time necessary to introduce the new more sustainable processes and products has to be diminished by linking their development with operational innovation management and with efficient environmental-political control procedures.

    Full Text Available Tourism industry records various economic, social, political and others influences and provides itself important position in the overall economic development of many countries. The analysis of the available data of tourist arrivals and number of tourist overnight stays in observed countries of the Western Balkans (Serbia, Macedonia, Montenegro led us to conduct research in order to determine tourism contribution to the overall economic growth. Based on the modified methodology used by Brida et al. (2008 for calculating real GDP growth rates and tourism contribution to the overall economic growth, the paper indicates that tourism makes a modest direct contribution to the overall economic growth in the examined countries, regardless of the continuous increase in the number of foreign tourist arrivals. The level of tourism contribution to the overall economic growth varies and it is primarily related to diversity and quality of supply (the highest contribution is recorded in Montenegro, while lowest contribution is observed in Macedonia.

    Full Text Available Many authors claim that to cope with rapid changes in social and productive environments, and especially for responding quickly to customer demands and / or users in an organization, information is needed and its management. Decision-making processes also take into account only the past experiences, and this model no longer meets the precepts of today's corporate world, considering the speed with which the market and competition are in search of improvement. Centered on the concepts of Competitive Intelligence and Artificial Intelligence, this article aims to show the importance of information processing, focusing on the processes of decision making and provide a model for their organization and storage. The findings point to the use of intelligent systems, contributing to improved decision-making process and seeking to obtain answers with high quality standards relating to market demand.

    Self-contribution to the income (individual achievement) was an important factor which needs to be taken into individual's fairness considerations. This study aimed at elucidating the modulation of self-contribution to the income, on recipient's responses to unfairness in the Ultimatum Game. Eighteen participants were scanned while they were playing an adapted version of the Ultimatum Game as responders. Before splitting money, the proposer and the participant (responder) played the ball-guessing game. The responder's contribution to the income was manipulated by both the participant's and the proposer's accuracy in the ball-guessing game. It turned out that the participants more often rejected unfair offers and gave lower fairness ratings when they played a more important part in the earnings. At the neural level, anterior insula, anterior cingulate cortex, dorsolateral prefrontal cortex and temporoparietal junction showed greater activities to unfairness when self-contribution increased, whereas ventral striatum and medial orbitofrontal gyrus showed higher activations to fair (vs unfair) offers in the other-contributed condition relative to the other two. Besides, the activations of right dorsolateral prefrontal cortex during unfair offers showed positive correlation with rejection rates in the self-contributed condition. These findings shed light on the significance of self-contribution in fairness-related social decision-making processes. © The Author (2013). Published by Oxford University Press.

    The ability to make advantageous decisions under circumstances in which there is a risk of adverse consequences is an important component of adaptive behavior; however, extremes in risk taking (either high or low) can be maladaptive and are characteristic of a number of neuropsychiatric disorders. To better understand the contributions of various affective and cognitive factors to risky decision making, cohorts of male Long-Evans rats were trained in a "Risky Decision making Task" (RDT), in which they made discrete trial choices between a small, "safe" food reward and a large, "risky" food reward accompanied by varying probabilities of footshock. Experiment 1 evaluated the relative contributions of the affective stimuli (i.e., punishment vs. reward) to RDT performance by parametrically varying the magnitudes of the footshock and large reward. Varying the shock magnitude had a significant impact on choice of the large, "risky" reward, such that greater magnitudes were associated with reduced choice of the large reward. In contrast, varying the large, "risky" reward magnitude had minimal influence on reward choice. Experiment 2 compared individual variability in RDT performance with performance in an attentional set shifting task (assessing cognitive flexibility), a delayed response task (assessing working memory), and a delay discounting task (assessing impulsive choice). Rats characterized as risk averse in the RDT made more perseverative errors on the set shifting task than did their risk taking counterparts, whereas RDT performance was not related to working memory abilities or impulsive choice. In addition, rats that showed greater delay discounting (greater impulsive choice) showed corresponding poorer performance in the working memory task. Together, these results suggest that reward-related decision making under risk of punishment is more strongly influenced by the punishment than by the reward, and that risky and impulsive decision making are associated with

    In Japan's primary and secondary schools, radiation and radioactivity are taught as part of the curriculum dealing with social science subjects. Students learn much about the hazardous features of radiation, but lack the scientific understanding necessary to build a more balanced picture. Although the same point applies to education covering the harmful effects of volcanic eruptions, earthquakes, electrical storms and so on, public understanding of these events is relatively high and students are generally able to make informed judgments about the risks involved. By contrast, their limited understanding of radiation often contributes to fears that it is evil or even supernatural. To correct this distortion, it is important that primary and secondary education includes a scientific explanation of radiation. Like heat and light, radiation is fundamental to the history of the universe; and scientific education programs should give appropriate emphasis to this important subject. Students would then be able to make more objective judgments about the useful and hazardous aspects of radiation. (author)

    Soil in alpine environments plays a key role in the development of ecosystem services and in order to maintain and preserve this important resource, information is required on processes that lead to soil erosion. Similar to other mountain alpine environments, the Benasque catchment is characterised by temperatures below freezing that can last from November to April, intense rainfall events, typically in spring and autumn, and rugged topography which makes assessment of erosion challenging. Indirect approaches to soil erosion assessment, such as combined model approaches, offer an opportunity to evaluate soil erosion in such areas. In this study (i) the SWAT (Soil and Water Assessment Tool) hydrological and erosion model and (ii) sediment fingerprinting procedures were used in parallel to assess the viability of a combined modelling and tracing approach to evaluate soil erosion processes in the area of the Posets-Maladeta Natural Park (central Spanish Pyrenees). Soil erosion rates and sediment contribution of potential sediment sources defined by soil type (Kastanozems/Phaeozems; Fluvisols and Cambisols) were assessed. The SWAT model suggested that, with the highest specific sediment yields, Cambisols are the main source of sediment in the Benasque catchment and Phaeozems and Fluvisols were identified as the lowest sediment contributors. Spring and winter model runs gave the highest and lowest specific sediment yield, respectively. In contrast, sediment fingerprinting analysis identified Fluvisols, which dominate the riparian zone, as the main sediment source at the time of sampling. This indicates the importance of connectivity as well as potential differences in the source dynamic of material in storage versus that transported efficiently from the system at times of high flow. The combined approach enabled us to better understand soil erosion processes in the Benasque alpine catchment, wherein SWAT identified areas of potential high sediment yield in large flood

    © 2014 American Chemical Society. The measurement of isosteric heats of adsorption of silica supported amine materials in the low pressure range (0- 0.1 bar) is critical for understanding the interactions between CO2 and amine sites at low coverage and hence to the development of efficient amine adsorbents for CO2 capture from flue gas and ambient air. Heats of adsorption for an array of silica-supported amine materials are experimentally measured at low coverage using a Calvet calorimeter equipped with a customized dosing manifold. In a series of 3-aminopropylfunctionalized silica materials, higher amine densities resulted in higher isosteric heats of adsorption, clearly showing that the density/proximity of amine sites can influence the amine efficiency of adsorbents. In a series of materials with fixed amine loading but different amine types, strongly basic primary and secondary amine materials are shown to have essentially identical heats of adsorption near 90 kJ/mol. However, the adsorption uptakes vary substantially as a function of CO2 partial pressure for different primary and secondary amines, demonstrating that entropic contributions to adsorption may play a key role in adsorption at secondary amine sites, making adsorption at these sites less effi cient at the low coverages that are important to the direct capture of CO2 from ambient air. Thus, while primary amines are confirmed to be the most effective amine types for CO2 capture from ambient air, this is not due to enhanced enthalpic contributions associated with primary amines over secondary amines, but may be due to unfavorable entropic factors associated with organization of the second alkyl chain on the secondary amine during CO2 adsorption. Given this hypothesis, favorable entropic factors may be the main reason primary amine based adsorbents are more effective under air capture conditions.

    Late delivery and sick housing project problems were attributed to poor decision making. These problems are the string of housing developer that prefers to create their own approach based on their experiences and expertise with the simplest approach by just applying the obtainable standards and rules in decision making. This paper seeks to identify the decision making methods for housing development at the initiation phase in Malaysia. The research involved Delphi method by using questionnaire survey which involved 50 numbers of developers as samples for the primary stage of collect data. However, only 34 developers contributed to the second stage of the information gathering process. At the last stage, only 12 developers were left for the final data collection process. Finding affirms that Malaysian developers prefer to make their investment decisions based on simple interpolation of historical data and using simple statistical or mathematical techniques in producing the required reports. It was suggested that they seemed to skip several important decision-making functions at the primary development stage. These shortcomings were mainly due to time and financial constraints and the lack of statistical or mathematical expertise among the professional and management groups in the developer organisations.

    Although adults who sustain a severe traumatic brain injury (TBI) require support to make decisions in their lives, little is known about their experience of this process. The aim of this study was to explore how participation in decision making contributes to self-conceptualization in adults with severe TBI. We used constructivist grounded theory methods. Data included 20 in-depth interviews with adults with severe TBI. Through a process of constant comparison, analysis involved open and focused coding until clear categories emerged and data saturation was achieved. Self-conceptualization emerged as a complex and multifaceted process, as individuals with TBI aimed to reestablish a sense of autonomy. We describe a recursive relationship in which decision-making participation assists the dynamic construction of self, and self-concept contributes to the experience of making decisions. The role of an individual's social support network in acting as a bridge between participation and self-conceptualization is presented. Findings emphasize that contributing to decisions about one's own goals across a range of life areas can reinforce a positive self-concept. It is vital that supporters understand that participation in decision making provides a pathway to conceptualizing self and aim to maximize the person's participation in the decision-making process. Implications for Rehabilitation Previous research has identified that the experience of sustaining TBI has a significant impact on a person's conceptualization of self. This study identified that decision-making experiences play an important role in the ongoing process of self-conceptualization after injury. Decision-making experiences can reinforce a person's self-concept or lead them to revise (positively or negatively) their sense of self. By maximizing the person's decision-making participation, those around them can support them to develop positive self-attributes and contribute to shaping their future goals.

    We rarely, if ever, repeatedly encounter exactly the same situation. This makes generalization crucial for real world decision making. We argue that categorization, the study of generalizable representations, is a type of decision making, and that categorization learning research would benefit from approaches developed to study the neuroscience of decision making. Similarly, methods developed to examine generalization and learning within the field of categorization may enhance decision making research. We first discuss perceptual information processing and integration, with an emphasis on accumulator models. We then examine learning the value of different decision making choices via experience, emphasizing reinforcement learning modeling approaches. Next we discuss how value is combined with other factors in decision making, emphasizing the effects of uncertainty. Finally, we describe how a final decision is selected via thresholding processes implemented by the basal ganglia and related regions. We also consider how memory related functions in the hippocampus may be integrated with decision making mechanisms and contribute to categorization. PMID:23548891

    2013-01-01

    For structural models involving correlated input variables, a novel interpretation for variance-based importance measures is proposed based on the contribution of the correlated input variables to the variance of the model output. After the novel interpretation of the variance-based importance measures is compared with the existing ones, two solutions of the variance-based importance measures of the correlated input variables are built on the sparse grid numerical integration (SGI): double-loop nested sparse grid integration (DSGI) method and single loop sparse grid integration (SSGI) method. The DSGI method solves the importance measure by decreasing the dimensionality of the input variables procedurally, while SSGI method performs importance analysis through extending the dimensionality of the inputs. Both of them can make full use of the advantages of the SGI, and are well tailored for different situations. By analyzing the results of several numerical and engineering examples, it is found that the novel proposed interpretation about the importance measures of the correlated input variables is reasonable, and the proposed methods for solving importance measures are efficient and accurate. -- Highlights: •The contribution of correlated variables to the variance of the output is analyzed. •A novel interpretation for variance-based indices of correlated variables is proposed. •Two solutions for variance-based importance measures of correlated variables are built

    Full Text Available Our increasing dependence on information technologies and autonomous systems has escalated international concern for information- and cyber-security in the face of politically, socially and religiously motivated cyber-attacks. Information warfare tactics that interfere with the flow of information can challenge the survival of individuals and groups. It is increasingly important that both humans and machines can make decisions that ensure the trustworthiness of information, communication and autonomous systems. Subsequently, an important research direction is concerned with modelling decision-making processes. One approach to this involves modelling decision-making scenarios as games using game theory. This paper presents a survey of information warfare literature, with the purpose of identifying games that model different types of information warfare operations. Our contribution is a systematic identification and classification of information warfare games, as a basis for modelling decision-making by humans and machines in such scenarios. We also present a taxonomy of games that map to information warfare and cyber crime problems as a precursor to future research on decision-making in such scenarios. We identify and discuss open research questions including the role of behavioural game theory in modelling human decision making and the role of machine decision-making in information warfare scenarios.

  6. LNG imports make strong recovery in 1996; exports increase also

    LNG imports to the US jumped in 1996 as Algerian base-load plants resumed operations following major revamps. Exports from Alaska to Japan grew by nearly 4% over 1995. Total LNG imports to the US in 1996 were 40.27 bcf compared to 17.92 bcf in 1995, an increase of 124.8%. Algeria supplied 35.32 bcf; Abu Dhabi, 4.95 bcf. About 82.3% of the imported LNG was received at Distrigas Corp.'s terminal north of Boston. The remaining LNG was received at the Pan National terminal in Lake Charles, LA. LNG imports during 1995 fell to such a low level not because of depressed US demand but because of limited supply. The paper discusses LNG-receiving terminals, base-load producers, LNG pricing, and exports

  7. Importance of Sulfate Aerosol in Evaluating the Relative Contributions of Regional Emissions to the Historical Global Temperature Change

    2004-01-01

    During the negotiations of the Kyoto Protocol the delegation of Brazil presented an approach for distributing the burden of emissions reductions among the Parties based on the effect of their cumulative historical emissions on the global-average near-surface temperature. The Letter to the Parties does not limit the emissions to be considered to be only greenhouse gas (GHG) emissions. Thus, in this paper we explore the importance of anthropogenic SOx emissions that are converted to sulfate aerosol in the atmosphere, together with the cumulative greenhouse gas emissions, in attributing historical temperature change. We use historical emissions and our simple climate model to estimate the relative contributions to global warming of the regional emissions by four Parties: OECD90, Africa and Latin America, Asia, and Eastern Europe and the Former Soviet Union. Our results show that for most Parties the large warming contributed by their GHG emissions is largely offset by the correspondingly large cooling by their SOx emissions. Thus, OECD90 has become the dominant contributor to recent global warming following its large reduction in SOx emissions after 1980

  8. Dopamine and Effort-Based Decision Making

    Full Text Available Motivational theories of choice focus on the influence of goal values and strength of reinforcement to explain behavior. By contrast relatively little is known concerning how the cost of an action, such as effort expended, contributes to a decision to act. Effort-based decision making addresses how we make an action choice based on an integration of action and goal values. Here we review behavioral and neurobiological data regarding the representation of effort as action cost, and how this impacts on decision making. Although organisms expend effort to obtain a desired reward there is a striking sensitivity to the amount of effort required, such that the net preference for an action decreases as effort cost increases. We discuss the contribution of the neurotransmitter dopamine (DA towards overcoming response costs and in enhancing an animal’s motivation towards effortful actions. We also consider the contribution of brain structures, including the basal ganglia (BG and anterior cingulate cortex (ACC, in the internal generation of action involving a translation of reward expectation into effortful action.

    Full Text Available Expression "Development conditions and perspectives" became important for numerous analyses in various industrial and social areas. Several strategic documents and studies in last two decades analysed projects with topics on perspectives of future development in Serbia. Various tools are used for development of such documents, based on recent scientific and numerical solutions, thus providing reliable assessment for strategic decision making. Almost all analyses tried to implement the theories and practical experiences through the prism of "sustainable development", which included establishment of most important sustainability parameters. Analysis and ranking presented in this paper considered the potential of the Stavalj coal deposit, near city of Sjenica in Serbia, and feasibility of construction project of new mine and thermal power plant. Basis for analysis was a hybrid assessment model which takes into account principles of sustainable development. The model incorporates quantified SWOT analysis, which applies to active underground mines in Serbia. Special attention was given to the parameters describing potential for development.

    2017-10-01

    Full Text Available Deliberation is a basic rational human activity recognized since ancient times due to its role in decision making during daily life activities and in specialized areas of knowledge such as medicine, politics and ethics. The objective of this reflection paper is to study the contribution of Aristotle to the deliberative process through his work the Nicomachean Ethics, where the following aspects of deliberation were identified for analysis: origin, definition, characteristics, and types and conditions for its development. Bioethics defend these aspects, since it finds in Aristotelian phronesis the fundamental axis to guide its actions in search of human self-realization and the analysis and decision making of the clinical bioethical problems. Twenty-four centuries have passed until the importance of this process and the need to educate about it was finally rediscovered.

    The impact of research has traditionally been measured by citations to journal publications and used extensively for evaluation and assessment in academia, but this process misses the impact and reach of data and software as first-class scientific products. For traditional publications, Article-Level Metrics (ALM) capture the multitude of ways in which research is disseminated and used, such as references and citations within social media and other journal articles. Here we present on the extension of usage and citation metrics collection to include other artifacts of research, namely datasets. The Make Data Count (MDC) project will enable measuring the impact of research data in a manner similar to what is currently done with publications. Data-level metrics (DLM) are a multidimensional suite of indicators measuring the broad reach and use of data as legitimate research outputs. By making data metrics openly available for reuse in a number of different ways, the MDC project represents an important first step on the path towards the full integration of data metrics into the research data management ecosystem. By assuring researchers that their contributions to scholarly progress represented by data corpora are acknowledged, data level metrics provide a foundation for streamlining the advancement of knowledge by actively promoting desirable best practices regarding research data management, publication, and sharing.

  14. The Drug Reimbursement Decision-Making System in Iran.

    2014-05-01

    Previous studies of health policies in Iran have not focused exclusively on the drug reimbursement process. The aim of this study was to describe the entire drug reimbursement process and the stakeholders, and discuss issues faced by policymakers. Review of documents describing the administrative rules and directives of stakeholders, supplemented by published statistics and interviews with experts and policymakers. Iran has a systematic process for the assessment, appraisal, and judgment of drug reimbursements. The two most important organizations in this process are the Food and Drug Organization, which considers clinical effectiveness, safety, and economic issues, and the Supreme Council of Health Insurance, which considers various criteria, including budget impact and cost-effectiveness. Ultimately, the Iranian Cabinet approves a drug and recommends its use to all health insurance organizations. Reimbursed drugs account for about 53.5% of all available drugs and 77.3% of drug expenditures. Despite its strengths, the system faces various issues, including conflicting stakeholder aims, lengthy decision-making duration, limited access to decision-making details, and rigidity in the assessment process. The Iranian drug reimbursement system uses decision-making criteria and a structured approach similar to those in other countries. Important shortcomings in the system include out-of-pocket contributions due to lengthy decision making, lack of transparency, and conflicting interests among stakeholders. Iranian policymakers should consider a number of ways to remedy these problems, such as case studies of individual drugs and closer examination of experiences in other countries.

    It is usually assumed that Galen is one of the fathers of anatomy and that between the Corpus Galenicum and the Renaissance there was no major advance in anatomical knowledge. However, it is also consensually accepted that Muslim scholars had the intellectual leadership from the 8th/9th to 13th centuries, and that they made remarkable progresses in numerous scientific fields including medicine. So, how is it possible that they did not contribute to advance human anatomy during that period? According to the dominant view, Muslim scholars exclusively had a passive role: their transmission of knowledge from the Greeks to the West. Here, we summarize, for the first time in a single paper, the studies of major Muslim scholars that published on human anatomy before Vesalius. This summary is based on analyses of original Arabic texts and of more recent publications by anatomists and historians, and on comparisons between the descriptions provided by Galen and by these Muslim scholars. We show that Arabic speakers and Persians made important advances in human anatomy well before Vesalius. The most notable exception concerns the muscular system: strikingly, there were apparently neither advances made by Muslims nor by Westerners for more than 1000 years. Unbiased discussions of these and other related issues, and particularly of the mainly untold story about the major contributions of Muslim scholars to anatomy, are crucial to our knowledge of the history of anatomy, biology and sciences, and also of our way of thinking, biases, and prejudices.

    We examined whether anticipation is underpinned by perceiving structured patterns or postural cues and whether the relative importance of these processes varied as a function of task constraints. Skilled and less-skilled soccer players completed anticipation paradigms in video-film and point light display (PLD) format. Skilled players anticipated more accurately regardless of display condition, indicating that both perception of structured patterns between players and postural cues contribute to anticipation. However, the Skill×Display interaction showed skilled players' advantage was enhanced in the video-film condition, suggesting that they make better use of postural cues when available during anticipation. We also examined anticipation as a function of proximity to the ball. When participants were near the ball, anticipation was more accurate for video-film than PLD clips, whereas when the ball was far away there was no difference between viewing conditions. Perceiving advance postural cues appears more important than structured patterns when the ball is closer to the observer, whereas the reverse is true when the ball is far away. Various perceptual-cognitive skills contribute to anticipation with the relative importance of perceiving structured patterns and advance postural cues being determined by task constraints and the availability of perceptual information.

    After participating in this activity, learners should be better able to:• Assess the neuropsychological literature on decision making and the medical and legal assessment of capacity in patients with dementia• Identify the limitations of integrating findings from decision-making research into capacity assessments for patients with dementia ABSTRACT: Medical and legal professionals face the challenge of assessing capacity and competency to make medical, legal, and financial decisions in dementia patients with impaired decision making. While such assessments have classically focused on the capacity for complex reasoning and executive functions, research in decision making has revealed that motivational and metacognitive processes are also important. We first briefly review the neuropsychological literature on decision making and on the medical and legal assessment of capacity. Next, we discuss the limitations of integrating findings from decision-making research into capacity assessments, including the group-to-individual inference problem, the unclear role of neuroimaging in capacity assessments, and the lack of capacity measures that integrate important facets of decision making. Finally, we present several case examples where we attempt to demonstrate the potential benefits and important limitations of using decision-making research to aid in capacity determinations.

    Protected areas (PAs) are a cornerstone of conservation efforts and now cover nearly 13% of the world's land surface, with the world's governments committed to expand this to 17%. However, as biodiversity continues to decline, the effectiveness of PAs in reducing the extinction risk of species remains largely untested. We analyzed PA coverage and trends in species' extinction risk at globally significant sites for conserving birds (10,993 Important Bird Areas, IBAs) and highly threatened vertebrates and conifers (588 Alliance for Zero Extinction sites, AZEs) (referred to collectively hereafter as ‘important sites’). Species occurring in important sites with greater PA coverage experienced smaller increases in extinction risk over recent decades: the increase was half as large for bird species with>50% of the IBAs at which they occur completely covered by PAs, and a third lower for birds, mammals and amphibians restricted to protected AZEs (compared with unprotected or partially protected sites). Globally, half of the important sites for biodiversity conservation remain unprotected (49% of IBAs, 51% of AZEs). While PA coverage of important sites has increased over time, the proportion of PA area covering important sites, as opposed to less important land, has declined (by 0.45–1.14% annually since 1950 for IBAs and 0.79–1.49% annually for AZEs). Thus, while appropriately located PAs may slow the rate at which species are driven towards extinction, recent PA network expansion has under-represented important sites. We conclude that better targeted expansion of PA networks would help to improve biodiversity trends. PMID:22457717

    Full Text Available People and organizations make better or get wrong as consequence of making decisions. Sometimes making decisions is just a trial and error process. Some others, decisions are good and the results profitable with a few of mistakes, most of the time because it’s considered the experience and the control of a specific field or the good intention of who makes them. Actually, all kinds of decisions bring learning. What is important is the intention, the attitude and the values considered in this process. People from different scenes face many facts and circumstances—almost always out of control—that affect the making decisions process. There is not a unique way to make decisions for all companies in many settings. The person who makes a decision should identify the problem, to solve it later using alternatives and solutions. Even though, follow all the steps it’s not easy as it seems. Looking back the conditions related to the decisions, we can mention the followings: uncertainty, risk and certainty. When people identify circumstances and facts, as well as its effects in a possible situation, they will make decisions with certainty. As long as the information decreases and it becomes ambiguous the risk becomes an important factor in the making decisions process because they are connected to probable objectives (clear or subjective (opinion judgment or intuition. To finish, uncertainty, involves people that make a decision with no or little information about circumstances or criteria with basis

  2. Nursing research: can a feminist perspective make any contribution?

    1999-03-01

    As more than 90% of the RSA's nurses are women and as at least 50% of the health care clients are also women, nursing research can definitely benefit by incorporating feminist research approaches. Specific feminist research issues which could be relevant to nursing research include: inherent themes in feminist research feminist research methodology gender stereotypes and nursing research gender-based stereotypes of researchers potential benefits of incorporating feminist research approaches in nursing research. Most formal models of nursing, and thus also most nursing research based on these models, ignore gender issues. Thus they ignore part of the social reality of nursing and might provide distorted images of nursing. A feminist approach to nursing research could enhance the reality-based gender issues relevant to nursing specifically, and health care generally, and contribute towards rendering effective health care within a multidisciplinary health care context.

    Youth justice is an important public health issue. There is growing recognition of the need to adopt effective, evidence-based strategies for working with young offenders. Music interventions may be particularly well suited to addressing risk factors in young people and reducing juvenile crime. This systematic review of international research seeks to contribute to the evidence base on the impact of music making on the health, well-being and behaviour of young offenders and those considered at risk of offending. It examines outcomes of music making identified in quantitative research and discusses theories from qualitative research that might help to understand the impact of music making in youth justice settings.

    2016-11-10

    Reliance on moral principles and professional codes has given nurses direction for ethical decision-making. However, rational models do not capture the emotion and reality of human choice. Intuitive response must be considered. Supporting intuition as an important ethical decision-making tool for nurses, the aim of this study was to determine relationships between intuition, years of worked nursing experience, and perceived ethical decision-making ability. A secondary aim explored the relationships between rational thought to years of worked nursing experience and perceived ethical decision-making ability. A non-experimental, correlational research design was used. The Rational Experiential Inventory measured intuition and rational thought. The Clinical Decision Making in Nursing Scale measured perceived ethical decision-making ability. Pearson's r was the statistical method used to analyze three primary and two secondary research questions. A sample of 182 emergency nurses was recruited electronically through the Emergency Nurses Association. Participants were self-selected. Approval to conduct this study was obtained by the Adelphi University Institutional Review Board. A relationship between intuition and perceived ethical decision-making ability (r = .252, p = .001) was a significant finding in this study. This study is one of the first of this nature to make a connection between intuition and nurses' ethical decision-making ability. This investigation contributes to a broader understanding of the different thought processes used by emergency nurses to make ethical decisions. © The Author(s) 2016.

    Full Text Available The article presents a solution of a problem that is critical from a practical point of view: how to share a higher than usual discount of $10 million among 5 importers. The discount is a result of forming a coalition by 5 current, formerly competing, importers. The use of Shapley value as a concept for co-operative games yielded a solution that was satisfactory for 4 lesser importers and not satisfactory for the biggest importer. Appropriate modification of Shapley value presented in this article allowed to identify appropriate distribution of the saved purchase amount, which according to each player accurately reflects their actual strength and position on the importer market. A computer program was used in order to make appropriate calculations for 325 permutations of all possible coalitions. In the last chapter of this paper, we recognize the lasting contributions of Lloyd Shapley to the cooperative game theory, commemorating his recent (March 12, 2016 descent from this world.

    2005-01-01

    This paper draws on an exploratory research study to examine the effectiveness of health impact assessments in Wales. Through the review of five case study health impact assessments the research identified a number of benefits of the process in terms of skills and knowledge development amongst participants. The indirect contributions to decision-making were also evident including the way in which health impact assessment provided useful insights into the local community's perspective and raised awareness about the wider determinants of health. The process was also useful in establishing a dialogue between different stakeholders, which indirectly assisted decision-making and implementation. The direct links between health impact assessment and decision-making were more difficult to trace and this paper puts forward a number of suggestions for making those links more transparent. Suggestions include integrating decision-makers and clarifying the intended links to decision-making at the start of the health impact assessment process. Mainstreaming health impact assessment so that it is triggered as a routine part of all decision-making would help ensure it stands the best chance of informing decisions

  13. The influence of number line estimation precision and numeracy on risky financial decision making.

    Park, Inkyung; Cho, Soohyun

    2018-01-10

    This study examined whether different aspects of mathematical proficiency influence one's ability to make adaptive financial decisions. "Numeracy" refers to the ability to process numerical and probabilistic information and is commonly reported as an important factor which contributes to financial decision-making ability. The precision of mental number representation (MNR), measured with the number line estimation (NLE) task has been reported to be another critical factor. This study aimed to examine the contribution of these mathematical proficiencies while controlling for the influence of fluid intelligence, math anxiety and personality factors. In our decision-making task, participants chose between two options offering probabilistic monetary gain or loss. Sensitivity to expected value was measured as an index for the ability to discriminate between optimal versus suboptimal options. Partial correlation and hierarchical regression analyses revealed that NLE precision better explained EV sensitivity compared to numeracy, after controlling for all covariates. These results suggest that individuals with more precise MNR are capable of making more rational financial decisions. We also propose that the measurement of "numeracy," which is commonly used interchangeably with general mathematical proficiency, should include more diverse aspects of mathematical cognition including basic understanding of number magnitude. © 2018 International Union of Psychological Science.

  14. THE IMPORTANCE OF THE QUALITATIVE CHARACTERISTICS OF ACCOUNTING INFORMATION FOR DECISION MAKING . EMPIRICAL STUDY CONDUCTED IN THE HOSPITALITY INDUSTRY IN ROMANIA

    2015-07-01

    Full Text Available Hospitality industry is a sector of the national and world economy facing one of the most dynamic developments of the third millennium as if against the fact that it does not only face challenges of the economic crisis, but also the changes in the market, the perception and consumer behavior and of technological trends . The contribution of accounting to the accomplishment of strategic objectives of the business managers in hospitality and tourism industry, is manifested in the form of ensuring the information necessary for monitoring, determining the degree of liability and the effect, at various jobs, which allows the detection of internal reserves, of uneconomic and unnecessary expenses and of losses. Convinced of the vital importance of accounting information for all sectors of activity, and hence the hospitality and tourism industry, but also motivated by the unexplored potential in this sector we wanted to find "live" the perception of Romanian hospitality industry managers on the usefulness of accounting information, especially of that provided by management accounting, and how to exploit it in decision making process. Therefore, we pondered it was time to get into the "natural environment" of managers in the hospitality industry and find "at home in the field", for we can say that work is a second home, which is the importance given to the accounting information, which management accounting practices apply to survive in a market that offers many opportunities, yet many challenges, too. The entry into the natural environment was made by empirical research and is based on a survey conducted between November 2012 and January 2013, using a questionnaire as a tool consisting of 38 questions, administered online and on location to managers in the Bihor hospitality industry. The total population consisted of 146 entities in this sector, the sample being made up of 91 tourism entities, with a response rate of 62.33%, due to movements in the

    Decreased treatment adherence in patients with diabetes mellitus type 1 (type 1 DM) may reflect impairments in decision-making and underlying associated deficits in working memory and executive functioning. Other factors, including comorbid major depression, may also interfere with decision-making. The authors sought to review the clinically relevant characteristics of decision-making in type 1 DM by surveying the literature on decision-making by patients with type 1 DM. Deficiencies in decision-making in patients with type 1 DM or their caregivers contribute to treatment nonadherence and poorer metabolic control. Animal models of type 1 DM reveal deficits in hippocampal-dependent memory tasks, which are reversible with insulin. Neurocognitive studies of patients with type 1 DM reveal lowered performance on ability to apply knowledge to solve problems in a new situation and acquired scholarly knowledge, psychomotor efficiency, cognitive flexibility, visual perception, speed of information-processing, and sustained attention. Other factors that might contribute to poor decision-making in patients with type 1 DM, include "hypoglycemia unawareness" and comorbid major depression (given its increased prevalence in type 1 DM). Future studies utilizing novel treatment strategies to help patients with type 1 DM make better decisions about their disease may improve their glycemic control and quality of life, while minimizing the impact of end-organ disease.

    Damage to the ventromedial frontal cortex (VMFC) in humans is associated with deficits in decision making. Decision making, however, often happens while people are interacting with others, where it is important to take the social consequences of a course of action into account. It is well known that VMFC lesions also lead to marked alterations in patients' emotions and ability to interact socially; however, it has not been clear which parts of the VMFC are critical for these changes. Recently, there has been considerable interest in the role of the VMFC in choice behavior during interpersonal exchanges. Here, we highlight recent research that suggests that two areas within or adjacent to the VMFC, the orbitofrontal cortex (OFC) and the anterior cingulate cortex (ACC), may play distinct but complementary roles in mediating normal patterns of emotion and social behavior. Converging lines of evidence from human, macaque, and rat studies now suggest that the OFC may be more specialized for simple emotional responses, such as fear and aggression, through its role in representing primary reinforcement or punishment. By contrast, the ACC may play a distinct role in more complex aspects of emotion, such as social interaction, by virtue of its connections with the discrete parts of the temporal lobe and subcortical structures that control autonomic responses.

    Full Text Available Tourism sector is one of the sectors that gain momentum and importance with the globalization. One of the important sub branches of the tourism that attracts attention with 1 - 1 - 5 billion people and approximately 2 trillion world incomes is sport tourism. The first tourism movement is the start of Olympics in Ancient Greek and movement of people who want to watch these games. Due to the fact that this tourism type that emerges thanks to the sports activities, contributes the economic and social structure of that region, states carry out significant lobbying activities to host Olympics. The mass of the number of the sportsmen to attend to the sport activity and audience that come to watch these games and more importantly live s treams from the place of the games contribute significantly to the promotion of that region. While eating and drinking, traveling, souvenirs expenses are direct incomes; it significantly contributes to the transportation and carriage sector. The appearance of before and after of the Olympic regions show great difference. One of the most important examples is the province of Mersin that hosts the latest Mediterranean games. While infrastructure and supra structure investments made for the preparation of city to the games in a brief time change the appearance of the city, national and international promotions significantly change the province. Olympic causes important development beyond measure. The objective of this study is to specify social and economic con tributions of tourism type emerged by the sport activities on the region and raise awareness for its contribution to country promotion. The study bases significantly on the literature review. The study will have a solid structure by making use of the dome stic and international statistical data. The scope of the study is Olympics in general and Mediterranean games in Mersin Province in particular.

    Patients and families coping with a terminal illness are faced with a number of decisions over the course of their disease. The role that family communication plays in the process of decision making is an important one. The objectives for this review are to examine the current state of empirical literature on the relationship between family communication and decision making about end-of-life care, to identify gaps, and to discuss implications for policy, practice, and future research. Articles were identified using systematic keyword searches within the following relevant databases: Academic Search Complete, CINAHL Plus, Communications and Mass Media Complete, ERIC, PsychINFO, MEDLINE, SocINDEX, and ProQuest. The three bodies of relevant literature that emerged during this review include: (1) the importance of family communication at the end of life (EoL); (2) family decision making at the EoL; and (3) the interrelationship of communication (both within the family and with healthcare professionals) and decision making at the EoL. While the literature highlights the role of communication between medical professionals and the patient or family members, there is very little focus on the process of how family communication among the family members themselves contributes to decision making at the end of life. Barriers to end-of-life care are important considerations for helping patients to access timely and appropriate services. Understanding the pertinent role of family communication as it relates to the decision for EoL care is the first step in working to provide another avenue for overcoming these barriers.

    For reducing health impacts from air pollution, it is important to know the sources contributing to human exposure. This study systematically reviewed and analysed available source apportionment studies on particulate matter (of diameter of 10 and 2.5 microns, PM10 and PM2.5) performed in cities to estimate typical shares of the sources of pollution by country and by region. A database with city source apportionment records, estimated with the use of receptor models, was also developed and available at the website of the World Health Organization. Systematic Scopus and Google searches were performed to retrieve city studies of source apportionment for particulate matter. Six source categories were defined. Country and regional averages of source apportionment were estimated based on city population weighting. A total of 419 source apportionment records from studies conducted in cities of 51 countries were used to calculate regional averages of sources of ambient particulate matter. Based on the available information, globally 25% of urban ambient air pollution from PM2.5 is contributed by traffic, 15% by industrial activities, 20% by domestic fuel burning, 22% from unspecified sources of human origin, and 18% from natural dust and salt. The available source apportionment records exhibit, however, important heterogeneities in assessed source categories and incompleteness in certain countries/regions. Traffic is one important contributor to ambient PM in cities. To reduce air pollution in cities and the substantial disease burden it causes, solutions to sustainably reduce ambient PM from traffic, industrial activities and biomass burning should urgently be sought. However, further efforts are required to improve data availability and evaluation, and possibly to combine with other types of information in view of increasing usefulness for policy making.

  1. The Contribution of Smoking to Educational Gradients in U.S. Life Expectancy*

    2014-01-01

    Researchers have documented widening educational gradients in mortality in the United States since the 1970s. While smoking has been proposed as a key explanation for this trend, no prior study has quantified the contribution of smoking to increasing education gaps in longevity. We estimate the contribution of smoking to educational gradients in life expectancy using data on white men and women aged 50 and above from the National Longitudinal Mortality Study (N=283,430; 68,644 deaths) and the National Health Interview Survey (N=584,811; 127,226 deaths) in five periods covering the 1980s to 2006. In each period, smoking makes an important contribution to education gaps in longevity for white men and women. Smoking accounts for half the increase in the gap for white women but does not explain the widening gap for white men in the most recent period. Addressing greater initiation and continued smoking among the less educated may reduce mortality inequalities. PMID:26199287

    The purpose of this article is to situate decision-making aids in the energy area in France and show how the tools have changed over time as a function of the changing economic and political context. The challenges faced, already important in the post-war era due to reconstruction, are now huge due to supply constraints and global warming. While it is the State's responsibility to address these issues, as the players in the energy area currently are mainly in the private sphere, we look at decisions taken both by the State and by companies. Schematically, we compare two major periods: that of post-war planning through the eighties, and that of risk management, which has been current practice since market deregulation. From the methodological standpoint, we show that decision-making aids borrow tools from varied disciplines ranging from economics through management to futurology and long range planning. (author)

    An important, and yet unresolved question in natural resource management is how best to manage natural elements and their associated values to ensure human wellbeing. Specifically, there is a lack of measurement tools to assess the contribution of nature to people. We present one approach to overcome this global issue and show that the preferred state of any system element, in terms of realising human values, is a function of element properties. Consequently, natural resource managers need to understand the nature of the relationships between element properties and values if they are to successfully manage for human wellbeing. In two case studies of applied planning, we demonstrate how to identify key element properties, quantify their relationships to priority human values, and combine this information to model the contribution of elements to human wellbeing. In one of the two case studies we also compared the modelling outputs with directly elicited stakeholder opinions regarding the importance of the elements for realising the given priority values. The two, largely congruent outputs provide additional support for the approach. The study shows that rating sets of elements on their relative overall value for human wellbeing, or utility, provides critical information for subsequent management decisions and a basis for productive new research. We consider that the described approach is broadly applicable within the domain of natural resource management. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

  4. Moving toward comprehensive acute heart failure risk assessment in the emergency department: the importance of self-care and shared decision making.

    Collins, Sean P; Storrow, Alan B

    2013-08-01

    Nearly 700,000 emergency department (ED) visits were due to acute heart failure (AHF) in 2009. Most visits result in a hospital admission and account for the largest proportion of a projected $70 billion to be spent on heart failure care by 2030. ED-based risk prediction tools in AHF rarely impact disposition decision making. This is a major factor contributing to the 80% admission rate for ED patients with AHF, which has remained unchanged over the last several years. Self-care behaviors such as symptom monitoring, medication taking, dietary adherence, and exercise have been associated with decreased hospital readmissions, yet self-care remains largely unaddressed in ED patients with AHF and thus represents a significant lost opportunity to improve patient care and decrease ED visits and hospitalizations. Furthermore, shared decision making encourages collaborative interaction between patients, caregivers, and providers to drive a care path based on mutual agreement. The observation that “difficult decisions now will simplify difficult decisions later” has particular relevance to the ED, given this is the venue for many such issues. We hypothesize patients as complex and heterogeneous as ED patients with AHF may need both an objective evaluation of physiologic risk as well as an evaluation of barriers to ideal self-care, along with strategies to overcome these barriers. Combining physician gestalt, physiologic risk prediction instruments, an evaluation of self-care, and an information exchange between patient and provider using shared decision making may provide the critical inertia necessary to discharge patients home after a brief ED evaluation.

    Introduction Due to the increasing specialization of medical professionals, patients are treated by multiple disciplines. To ensure that delivered care is patient-centered, it is crucial that professionals and the patient together decide on treatment (shared decision making (SDM)). However, it is not known how SDM should be integrated in multidisciplinary practice. This study determines the most important factors for SDM implementation in sciatica care, as it is known that a prior inventory of factors is crucial to develop a successful implementation strategy. Methods 246 professionals (general practitioners, physical therapists, neurologists, neurosurgeons, orthopedic surgeons) (30% response) and 155 patients (96% response) responded to an internet-based survey. Respondents ranked barriers and facilitators identified in previous interviews, on their importance using Maximum Difference Scaling. Feeding back the personal top 5 most important factors, each respondent indicated whether these factors were barriers or facilitators. Hierarchical Bayes estimation was used to estimate the relative importance (RI) of each factor. Results Professionals assigned the highest importance to: quality of professional-patient relationship (RI 4.87; CI 4.75–4.99); importance of quick recovery of patient (RI 4.83; CI 4.69–4.97); and knowledge about treatment options (RI 6.64; CI 4.53–4.74), which were reported as barrier and facilitator. Professionals working in primary care had a different ranking than those working in hospital care. Patients assigned the highest importance to: correct diagnosis by professionals (barrier, RI 8.19; CI 7.99–8.38); information provision about treatment options and potential harm and benefits (RI 7.87; CI 7.65–8.08); and explanation of the professional about the care trajectory (RI 7.16; CI 6.94–7.38), which were reported as barrier and facilitator. Conclusions Knowledge, information provision and a good relationship are the most important

    This study explored the process of decision making about hospice enrollment and identified factors that influence the timing of that decision. This study employed an exploratory, descriptive, cross-sectional design and was conducted using qualitative methods. In-depth in-person semistructured interviews were conducted with 36 hospice patients and 55 caregivers after 2 weeks of hospice care. The study was guided by Janis and Mann's conflict theory model (CTM) of decision making. Qualitative data analysis involved a directed content analysis using concepts from the CTM. A model of hospice enrollment decision making is presented. Concepts from the CTM (appraisal, surveying and weighing the alternatives, deliberations, adherence) were used as an organizing framework to illustrate the dynamics. Distinct differences were found by diagnosis (cancer vs. other chronic illness, e.g., heart and lung diseases) during the pre-encounter phase or before the hospice referral but no differences emerged during the post-encounter phase. Differences in decision making by diagnosis suggest the need for research about effective means for tailored communication in end-of-life decision making by type of illness. Recognition that decision making about hospice admission varies is important for clinicians who aim to provide person-centered and family-focused care.

    Problem: The professional practice of engineering always involves engineering management, but it is difficult to know what specifically to include in the undergraduate curriculum. Approach: The population of New Zealand practising engineers was surveyed to determine the importance they placed on specific professional practice and engineering management competencies. Findings: Results show that communication and project planning were the two most important topics, followed by others as identified. The context in which practitioners use communication skills was found to be primarily with project management, with secondary contexts identified. The necessity for engineers to develop the ability to use multiple soft skills in an integrative manner is strongly supported by the data. Originality: This paper is one of only a few large-scale surveys of practising engineers to have explored the soft skill attributes. It makes a didactic contribution of providing a ranked list of topics which can be used for designing the curriculum and prioritising teaching effort, which has not previously been achieved. It yields the new insight that combinations of topics are sometimes more important than individual topics.

  10. A decision-oriented measure of uncertainty importance for use in PSA

    International Nuclear Information System (INIS)

    Poern, Kurt

    1997-01-01

    For the interpretation of the results of probabilistic risk assessments it is important to have measures which identify the basic events that contribute most to the frequency of the top event but also to identify basic events that are the main contributors to the uncertainty in this frequency. Both types of measures, often called Importance Measure and Measure of Uncertainty Importance, respectively, have been the subject of interest for many researchers in the reliability field. The most frequent mode of uncertainty analysis in connection with probabilistic risk assessment has been to propagate the uncertainty of all model parameters up to an uncertainty distribution for the top event frequency. Various uncertainty importance measures have been proposed in order to point out the parameters that in some sense are the main contributors to the top event distribution. The new measure of uncertainty importance suggested here goes a step further in that it has been developed within a decision theory framework, thereby providing an indication of on what basic event it would be most valuable, from the decision-making point of view, to procure more information

    Scientific research performed with the involvement of the broader public (the crowd) attracts increasing attention from scientists and policy makers. A key premise is that project organizers may be able to draw on underused human resources to advance research at relatively low cost. Despite a growing number of examples, systematic research on the effort contributions volunteers are willing to make to crowd science projects is lacking. Analyzing data on seven different projects, we quantify the financial value volunteers can bring by comparing their unpaid contributions with counterfactual costs in traditional or online labor markets. The volume of total contributions is substantial, although some projects are much more successful in attracting effort than others. Moreover, contributions received by projects are very uneven across time-a tendency toward declining activity is interrupted by spikes typically resulting from outreach efforts or media attention. Analyzing user-level data, we find that most contributors participate only once and with little effort, leaving a relatively small share of users who return responsible for most of the work. Although top contributor status is earned primarily through higher levels of effort, top contributors also tend to work faster. This speed advantage develops over multiple sessions, suggesting that it reflects learning rather than inherent differences in skills. Our findings inform recent discussions about potential benefits from crowd science, suggest that involving the crowd may be more effective for some kinds of projects than others, provide guidance for project managers, and raise important questions for future research.

    Procrastination is the action of delaying or postponing something such as making a decision or starting or completing some tasks or activities. According to previous studies, students who have a strong tendency to procrastinate get low scores in their tests, resulting in poorer academic performance compared to those who do not procrastinate. This study aims to identify the procrastination factors in completing assignments among three groups of undergraduate students. The relative importance of procrastination factors was quantified by the relative importance index (RII) method prior to ranking. A multistage sampling technique was used in selecting the sample. The findings revealed that `too many works in one time' is one of the top three factors contributing to procrastination in all groups.

  14. Testing the ability of a semidistributed hydrological model to simulate contributing area

    2016-06-01

    A dry climate, the prevalence of small depressions, and the lack of a well-developed drainage network are characteristics of environments with extremely variable contributing areas to runoff. These types of regions arguably present the greatest challenge to properly understanding catchment streamflow generation processes. Previous studies have shown that contributing area dynamics are important for streamflow response, but the nature of the relationship between the two is not typically understood. Furthermore, it is not often tested how well hydrological models simulate contributing area. In this study, the ability of a semidistributed hydrological model, the PDMROF configuration of Environment Canada's MESH model, was tested to determine if it could simulate contributing area. The study focused on the St. Denis Creek watershed in central Saskatchewan, Canada, which with its considerable topographic depressions, exhibits wide variation in contributing area, making it ideal for this type of investigation. MESH-PDMROF was able to replicate contributing area derived independently from satellite imagery. Daily model simulations revealed a hysteretic relationship between contributing area and streamflow not apparent from the less frequent remote sensing observations. This exercise revealed that contributing area extent can be simulated by a semi-distributed hydrological model with a scheme that assumes storage capacity distribution can be represented with a probability function. However, further investigation is needed to determine if it can adequately represent the complex relationship between streamflow and contributing area that is such a key signature of catchment behavior.

There are nations whose GDP consists of 40% of the total contribution of tourism to this indicator. One such segment requires permanent research of its economic, social and sustainability dimensions and their importance. This study outlines an overview of the main aspects related to economic and social importance of tourism and how tourism relates to the concept of sustainable development. The total contribution and the direct contribution of tourism to GDP are elements studied within this research. It is also studied the direct contribution of tourism to employment, and the main positive and negative effects of tourism on social life.

  1. Adaptive Importance Sampling with a Rapidly Varying Importance Function

    International Nuclear Information System (INIS)

    Booth, Thomas E.

    2000-01-01

    It is known well that zero-variance Monte Carlo solutions are possible if an exact importance function is available to bias the random walks. Monte Carlo can be used to estimate the importance function. This estimated importance function then can be used to bias a subsequent Monte Carlo calculation that estimates an even better importance function; this iterative process is called adaptive importance sampling.To obtain the importance function, one can expand the importance function in a basis such as the Legendre polynomials and make Monte Carlo estimates of the expansion coefficients. For simple problems, Legendre expansions of order 10 to 15 are able to represent the importance function well enough to reduce the error geometrically by ten orders of magnitude or more. The more complicated problems are addressed in which the importance function cannot be represented well by Legendre expansions of order 10 to 15. In particular, a problem with a cross-section notch and a problem with a discontinuous cross section are considered

    This is the first time that stable carbon, nitrogen and oxygen isotope analyses of human bones and teeth have been used to reconstruct subsistence and settlement patterns of prehispanic ceramic societies from Central Chile. Isotope analyses, unlike the evidence from botanical, faunal and artifactual remains from archaeological sites, and from dental and skeletal pathologies, gave information of which resources were really eaten by each individual during the last years of their life. The human data were evaluated against isotopic values of marine and terrestrial resources from central Chile. These results were interpreted taking into consideration different lines of paleodiet evidence. The main contributions are: empirical evidence of dietary differences according to cultural groups; low dependence on marine foods for most people living on the coast; indirect evidence of mobility strategies that show differences between Early and Late Intermediate societies; increased dependence on maize with time, especially among the Aconcagua people; gender differences in maize consumption for the same Aconcagua groups, men showing the greatest levels of maize intake. The results support some hypotheses, such as the difference in dietary patterns between contemporary Bato and Lolleo groups, contradict others, such as the supposed importance of marine diet for coastal inhabitants, and open new research questions for the future [es

    Evaluating long-term air quality trends can demonstrate effectiveness of control strategies and guide future air quality management planning. Observations have shown that ozone (O3) and fine particulate matter (PM2.5) in the US have declined since as early as 1980 in some areas. But observation trends alone cannot separate effects of changes in local and global emissions to US air quality which are important to air quality planners. This study uses a regional model (CAMx) nested within a global model (GEOS-Chem) to characterize regional changes in O3 and PM2.5 due to the intercontinental transport and local/regional emissions representing six modeling years within five decades (1970-2020). We use the CAMx Source Apportionment Technology (OSAT/PSAT) to estimate contributions from 6 source sectors in 7 source regions plus 6 other groups for a total of 48 tagged contributions. On-road mobile sources consistently make the largest U.S. anthropogenic emissions contribution to O3 in all cities examined even though they decline substantially from 1970 to 2005 and also from 2005 to 2020. Off-road mobile source contributions increase from 1970 to 2005 and then decrease after 2005 in all of the cities. The boundary conditions, mostly from intercontinental transport, contribute more than 20 ppb to high maximum daily 8-h average (MDA8) O3 for all six years. We found that lowering NOx emissions raises O3 formation efficiency (OFE) across all emission categories which will limit potential O3 benefits of local NOx strategies in the near future. PM2.5 benefited from adoption of control devices between 1970 and 1980 and has continued to decline through 2005 and expected to decline further by 2020. Area sources such as residential, commercial and fugitive dust emissions stand out as making large contributions to PM2.5 that are not declining. Inter-regional transport is less important in 2020 than 1990 for both pollutants.

  5. The importance of making right knowledge about radiation popular. Activity of 'radiation education forum'

    Radiation and radionuclides are not only indispensable in medical diagnoses and treatments, but are widely used in fundamental researches in various fields and in industry, thus contribute much to humans for elevating the quality of life. Nuclear power production is also playing an important role in saving the nonrenewable natural energy resources, without producing potentially problematic carbon dioxide. However, a majority of people has an excessive concern for radiation and radioactivity even for very minute quantities. This is due to the following three facts: (1) the first use of nuclear energy as the disastrous weapon in 1945 has resulted a profound after-effect in socio-psychological sense especially in Japan, (2) the major accidents of nuclear power plants which occurred in 1980's have been repeatedly reported in mass media with undue sensationalism, and (3) the proposition, that every ray of ionizing radiation may destroy DNA of human cells and is harmful by bringing carcinogenic or hereditary effects, has fixed as a suspicion-free common sense for general public. This proposition has its basis on the recommendation by ICRP of adopting the LNT (linear non-threshold), model even for low dose of radiations comparative with the natural radiation level. Thus the majority of people shows the syndrome of radio phobia'. Because there are so many risks other than radiation in the present day civilization, the extremely severe regulation only of radiation has many social demerits, and it is highly necessary that this situation be improved, by making the correct scientific information popular to the public. As an approach to this goal, a voluntary group, 'Radiation Education Forum', comprised of scientists, schoolteachers, journalists and citizens, has been established in 1994 in Japan, and has continued various types of activities. Because the social education has its basis on the school education, we have focussed our energy mainly for improving the education

    The designer of a nuclear plant must know the plant's associated risk limitations so that he can design the plant accordingly. To design a safety system, he must understand its importance and how it relates to the overall plant risk. The computer program RIO can aid the designer to understand a system's contribution to the plant's overall risk. The methodology developed and presented was sponsored by the Nuclear Research Applications Division of the Department of Energy for use in the Gas Cooled Fast Breeder Reactor (GCFR) Program. The principal motivation behind its development was the need to translate nuclear plants safety goals into reliability goals for systems which make up that plant. The method described herein will make use of the GCFR Accident Initiation and Progression Analyses (AIPA) event trees and other models in order to determine these reliability goals

    Decision-making experts emphasize that understanding and using probabilistic information are important for making informed decisions about medical treatments involving complex risk-benefit tradeoffs. Yet empirical research demonstrates that individuals may not use probabilities when making decisions. To explore decision making and the use of probabilities for decision making from the perspective of women who were risk-eligible to enroll in the Study of Tamoxifen and Raloxifene (STAR). We conducted narrative interviews with 20 women who agreed to participate in STAR and 20 women who declined. The project was based on a narrative approach. Analysis included the development of summaries of each narrative, and thematic analysis with developing a coding scheme inductively to code all transcripts to identify emerging themes. Interviewees explained and embedded their STAR decisions within experiences encountered throughout their lives. Such lived experiences included but were not limited to breast cancer family history, a personal history of breast biopsies, and experiences or assumptions about taking tamoxifen or medicines more generally. Women's explanations of their decisions about participating in a breast cancer chemoprevention trial were more complex than decision strategies that rely solely on a quantitative risk-benefit analysis of probabilities derived from populations In addition to precise risk information, clinicians and risk communicators should recognize the importance and legitimacy of lived experience in individual decision making. © The Author(s) 2015.

    Elite sporting performance results from the combination of innumerable factors, which interact with one another in a poorly understood but complex manner to mould a talented athlete into a champion. Within the field of sports science, elite performance is understood to be the result of both training and genetic factors. However, the extent to which champions are born or made is a question that remains one of considerable interest, since it has implications for talent identification and management, as well as for how sporting federations allocate scarce resources towards the optimisation of high-performance programmes. The present review describes the contributions made by deliberate practice and genetic factors to the attainment of a high level of sporting performance. The authors conclude that although deliberate training and other environmental factors are critical for elite performance, they cannot by themselves produce an elite athlete. Rather, individual performance thresholds are determined by our genetic make-up, and training can be defined as the process by which genetic potential is realised. Although the specific details are currently unknown, the current scientific literature clearly indicates that both nurture and nature are involved in determining elite athletic performance. In conclusion, elite sporting performance is the result of the interaction between genetic and training factors, with the result that both talent identification and management systems to facilitate optimal training are crucial to sporting success.

  9. Important atomic physics issues for ion beam fusion

    The nearly endless variety of interesting and challenging problems makes physics research enjoyable. Most of us would choose to be physicists even if physics had no practical applications. However, physics does have practical applications. This workshop deals with one of those applications, namely ion beam fusion. Not all interesting and challenging atomic physics questions are important for ion beam fusion. This paper suggests some questions that may be important for ion beam fusion. It also suggests some criteria for determining if a question is only interesting, or both interesting and important. Importance is time dependent and, because of some restrictions on the flow of information, also country dependent. In the early days of ion beam fusion, it was important to determine if ion beam fusion made sense. Approximate answers and bounds on various parameters were required. Accurate, detailed answers were not needed. Because of the efforts of many people attending this workshop, we now know that ion beam fusion does make some sense. We must still determine if ion beam fusion truly makes good sense. If it does make good sense, we must determine how to make it work. Accurate detailed answers are becoming increasingly important.

    2010-06-01

    The field of neonatology presents a fascinating context in which hugely important decisions have to be made on the basis of physicians' assessments of the long term consequences of various possible choices. In many cases such assessments cannot be derived from a consensual professional opinion; the situation is characterized by a high level of uncertainty. A sample of neonatologists in different countries received a questionnaire including vignette cases for which no clear consensus exists regarding the (probabilistic) prognosis. They were asked to (I) assess the probability of various outcomes (death, severe impairment) and (II) choose a treatment to be offered to the parents. Information on the physicians' professional and socio-demographic characteristics and their ethical "values" was also collected. The goal of this international survey is to understand the prognosis and to analyze decision making by professionals in the context of life and death in medicine. The availability of an identical technology in different social and institutional contexts should help identifying the convergences and differences under consideration. Seventy percent of those invited responded to the questionnaire (International 60-80%). Italian neonatologists seem to be quite pessimistic about the prognosis of infants at high risk of death or long term disabilities, they show a pro-life attitude, but in a certain proportion are willing to change their minds if requested by parents. Furthermore personal opinions predominate in the decision-making process and the contribution of team meeting and/or ethic consultation seem not significantly modify the decisions.

  11. Contributions of qualitative research to evidence-based practice in nursing

    2003-01-01

    Full Text Available AIM: This article aims to identify the contributions of qualitative research to evidence-based practice in nursing. BACKGROUND: Qualitative research dates back to the 1920s and 1930s, when anthropologists and sociologists used qualitative research methods to study human phenomena in naturalistic settings and from a holistic viewpoint. Afterwards, other subject matters, including nursing, adopted qualitative methods to answer their research questions. The restructuring of health care over the past decade has brought about increased accountability in nursing research. One method for increasing this accountability is evidence-based practice. METHOD: The method used was a search in the Cumulative Index to Nursing and Allied Health Literature database from 1999-present. The search resulted in 61 citations for evidence-based practice in nursing research; however, only 5 citations focused on evidence-based practice and qualitative research. FINDINGS: The authors' findings revealed six contributions of qualitative research to evidence-based practice: generation of hypotheses; development and validation of instruments; provision of context for evaluation; development of nursing interventions; development of new research questions; and application of Qualitative Outcome Analysis. CONCLUSION: Qualitative research makes important contributions to the quality of evidence-based practice.

    Full Text Available Cost reduction is among the main quoted reasons for logistics outsourcing, while transport capacities and operations are among the most outsourced logistics areas. However, according to transaction costs theory, there is often room for transport insourcing. Furthermore, nowadays many authors stress that mixed solutions can give better results than “make” or “buy” alternatives. “Make or buy” decision-making normative models, methods, and procedures in transport planning are not much explored. Instead, research is rather focused on carrier selection techniques, whereby it is supposed that outsourcing transport capacities is the most suitable solution. The purpose of this paper is to contribute to the body of literature on classical “makeor-buy” decision-making in transport fleet sizing in a non-logistics enterprise. It goes beyond the basic “make or buy” decisionmaking, and intermediate solutions (i.e., “make and buy” are explored. Practical directions are given according to theoretical principles, and a case study is used to exemplify the main deductions. The research also has practical implications. Many enterprises in transition economies have faced the question of what to do with their in-house transport fleets. The obtained results are of interest to merchants and manufacturing enterprises that already have a private transport fleet and are considering how to rationalize it.

    Gyrd-Jones, Richard; Törmälä, Minna

    Purpose: An important part of how we sense a brand is how we make sense of a brand. Sense-making is naturally strongly connected to how we cognize about the brand. But sense-making is concerned with multiple forms of knowledge that arise from our interpretation of the brand-related stimuli......: Declarative, episodic, procedural and sensory. Knowledge is given meaning through mental association (Keller, 1993) and / or symbolic interaction (Blumer, 1969). These meanings are centrally related to individuals’ sense of identity or “identity needs” (Wallpach & Woodside, 2009). The way individuals make...... sense of brands is related to who people think they are in their context and this shapes what they enact and how they interpret the brand (Currie & Brown, 2003; Weick, Sutcliffe, & Obstfeld, 2005; Weick, 1993). Our subject of interest in this paper is how stakeholders interpret and ascribe meaning...

    Full Text Available Involving youth in community and organizational decision-making is widely believed to lead to stronger communities. A promising strategy to foster decision-making is youth-adult partnerships in which youth and adults work collaboratively, sharing their strengths, collective knowledge, and decision-making power. A qualitative study of eight youth organizations showed that those organizations employing youth-adult partnership strategies were most effective in increasing youth's contributions to their communities. This article explores the elements of youth-adult partnership that were evident among successful organizations including: mutual respect, meaningful roles for youth, unique contributions of adults and youth, and shared decision-making and implications for youth development programs.

    2015-04-01

    Although various models of ethical decision making (EDM) have implicitly called upon constructs governed by working memory capacity (WMC), a study examining this relationship specifically has not been conducted. Using a sense making framework of EDM, we examined the relationship between WMC and various sensemaking processes contributing to EDM. Participants completed an online assessment comprised of a demographic survey, intelligence test, various EDM measures, and the Automated Operation Span task to determine WMC. Results indicated that WMC accounted for unique variance above and beyond ethics education, exposure to ethical issues, and intelligence in several sensemaking processes. Additionally, a marginally significant effect of WMC was also found with reference to EDM. Individual differences in WMC appear likely to play an important role in the ethical decision-making process, and future researchers may wish to consider their potential influences.

    2010-01-13

    In the last decade, great progress has been made in characterizing the accumulation of neural information during simple unitary perceptual decisions. However, much less is known about how sequentially presented evidence is integrated over time for successful decision making. The aim of this study was to study the mechanisms of sequential decision making in humans. In a magnetoencephalography (MEG) study, we presented healthy volunteers with sequences of centrally presented arrows. Sequence length varied between one and five arrows, and the accumulated directions of the arrows informed the subject about which hand to use for a button press at the end of the sequence (e.g., LRLRR should result in a right-hand press). Mathematical modeling suggested that nonlinear accumulation was the rational strategy for performing this task in the presence of no or little noise, whereas quasilinear accumulation was optimal in the presence of substantial noise. MEG recordings showed a correlate of evidence integration over parietal and central cortex that was inversely related to the amount of accumulated evidence (i.e., when more evidence was accumulated, neural activity for new stimuli was attenuated). This modulation of activity likely reflects a top-down influence on sensory processing, effectively constraining the influence of sensory information on the decision variable over time. The results indicate that, when making decisions on the basis of sequential information, the human nervous system integrates evidence in a nonlinear manner, using the amount of previously accumulated information to constrain the accumulation of additional evidence.

  3. Evolution of global contribution in multi-level threshold public goods games with insurance compensation

    2018-01-01

    Understanding voluntary contribution in threshold public goods games has important practical implications. To improve contributions and provision frequency, free-rider problem and assurance problem should be solved. Insurance could play a significant, but largely unrecognized, role in facilitating a contribution to provision of public goods through providing insurance compensation against the losses. In this paper, we study how insurance compensation mechanism affects individuals’ decision-making under risk environments. We propose a multi-level threshold public goods game model where two kinds of public goods games (local and global) are considered. Particularly, the global public goods game involves a threshold, which is related to the safety of all the players. We theoretically probe the evolution of contributions of different levels and free-riders, and focus on the influence of the insurance on the global contribution. We explore, in both the cases, the scenarios that only global contributors could buy insurance and all the players could. It is found that with greater insurance compensation, especially under high collective risks, players are more likely to contribute globally when only global contributors are insured. On the other hand, global contribution could be promoted if a premium discount is given to global contributors when everyone buys insurance.

    Full Text Available This podcast is a recording of a research seminar that took place on December 3, 2015, at the University of Westminster's Communication and Media Research Institute (CAMRI. In this contribution, David Gauntlett discusses his new book, Making Media Studies, and other new work. In Making Media Studies (Peter Lang, 2015, Gauntlett proposes a vision of media studies based around doing and making – not about the acquisition of skills, as such, but an experience of building knowledge and understanding through creative hands-on engagement with all kinds of media. Gauntlett suggests that media studies scholars have failed to recognise the significance of everyday creativity – the vital drive of people to make, exchange, and learn together, supported by online networks. He argues that we should think about media in terms of conversations, inspirations, and making things happen. Media studies can be about genuine social change, he suggests, if we recognise the significance of everyday creativity, work to transform our tools, and learn to use them wisely. David Gauntlett is a Professor in the School of Media, Arts and Design at the University of Westminster, where he is also the School's Co-Director of Research.

    2017-08-01

    Full Text Available Electricity is a vital factor underlying modern living standards, but there are many developing countries with low levels of electricity access and use. We seek to systematically identify the crucial elements underlying transitions toward greater electrification in developing countries. We use a cross-sectional regression approach with national-level data up to 2012 for 135 low- and middle-income countries. The paper finds that the effectiveness of governments is the most important governance attribute for encouraging the transition to increased electrification in developing countries, on average. The results add to the growing evidence on the importance of governance for development outcomes. Donors seeking to make more successful contributions to electrification may wish to target countries with more effective governments.

    2011-10-01

    Most current ethical decision-making models provide a logical and reasoned process for making ethical judgments, but these models are empirically unproven and rely upon assumptions of rational, conscious, and quasilegal reasoning. Such models predominate despite the fact that many nonrational factors influence ethical thought and behavior, including context, perceptions, relationships, emotions, and heuristics. For example, a large body of behavioral research has demonstrated the importance of automatic intuitive and affective processes in decision making and judgment. These processes profoundly affect human behavior and lead to systematic biases and departures from normative theories of rationality. Their influence represents an important but largely unrecognized component of ethical decision making. We selectively review this work; provide various illustrations; and make recommendations for scientists, trainers, and practitioners to aid them in integrating the understanding of nonrational processes with ethical decision making.

    Full Text Available Social contributions have an important impact on payroll policy. Also, social contributions represent a significant budgetary revenue item which can be viewed at the edge between taxation and insurance. Social contributions in Romania experienced many changes which ended in 2008. Nowadays, they are within a long transaction period towards partial externalization of the insurance activity to privately managed funds. The aim of this paper is to analyse the homogeneity of Romanian social security public scheme using annual data extracted from 2002-2009.The main findings reveal that social contributions reached the pinnacle of diversification, being too many, some of them with a small contribution rates; fiscal reforms which reduced contribution rates advantaged employers, and state will be interested to externalize this activity as far private sector will be able to assume this responsibility and the budgetary effects are acceptable for the public finance.

    Wind erosion following fire is an important landscape process that can result in the redistribution of ecologically important soil resources. In this study we evaluated the potential for a fire patch in a desert shrubland to serve as a source of biologically important nutrients to the adjacent, downwind, unburned ecosystem. We analyzed nutrient concentrations (P, K, Ca, Mg, Cu, Fe, Mn, Al) in wind-transported sediments, and soils from burned and adjacent unburned surfaces, collected during the first to second growing seasons after a wildfire that burned in 2007 in Idaho, USA in sagebrush steppe; a type of cold desert shrubland. We also evaluated the timing of potential wind erosion events and weather conditions that might have contributed to nutrient availability in downwind shrubland. Findings indicated that post-fire wind erosion resulted in an important, but transient, addition of nutrients on the downwind shrubland. Aeolian sediments from the burned area were enriched relative to both the up- and down-wind soil and indicated the potential for a fertilization effect through the deposition of the nutrient-enriched sediment during the first, but not second, summer after wildfire. Weather conditions that could have produced nutrient transport events might have provided increased soil moisture necessary to make nutrients accessible for plants in the desert environment. Wind transport of nutrients following fire is likely important in the sagebrush steppe as it could contribute to pulses of resource availability that might, for example, affect plant species differently depending on their phenology, and nutrient- and water-use requirements.

    1978-01-01

    The application of importance sampling as a variance reduction technique in Monte Carlo quasiclassical trajectory calculations is discussed. Two measures are proposed which quantify the quality of the importance sampling used, and indicate whether further improvements may be obtained by some other choice of importance sampling function. A general procedure for constructing standardized histogrammic representations of differential functions which integrate to the appropriate integral value obtained from a trajectory calculation is presented. Two criteria for ''optimum'' binning of these histogrammic representations of differential functions are suggested. These are (1) that each bin makes an equal contribution to the integral value, and (2) each bin has the same relative error. Numerical examples illustrating these sampling and binning concepts are provided

    Making better choices about future technologies that are being researched or developed is an important motivator behind lay ethics interventions. However, in practice, they do not always succeed to serve that goal. Especially authors who have noted that lay ethicists sometimes take recourse to well-known themes which stem from old, even 'archetypical' stories, have been criticized for making too little room for agency and decision-making in their approach. This paper aims to contribute to a reflection on how lay ethics can acquire more practical relevance. It will use resources in narrative ethics to suggest that in order to be relevant for action, facilitators of lay ethics interventions need to invite participants to engage in a narrative quest. As part of a quest, lay ethicists should be asked to (1) reflect on a specific question or choice, (2) use diverse (imaginative) input which is informative about the heterogeneity of viewpoints that are defended in society and (3) argue for their standpoints.

    Full Text Available The important managerial decision-making and the development of policies, strategies, internal normative acts and procedures must be solid grounded for efficient achieving of their objectives. To this end, the evidence-based approach uses various types of evidence, a leading role having those scientific, and the critical thinking. The evidence from behavioral sciences is especially important when the decisions objectives involve behavioral elements. They also help to ensure the rationality of any decision-making process. The concern for the use of behavioral sciences research in the decision-making preceded the occurrence of evidence-based approach. The increased knowledge fund of organizations, the access to the best practices and to the relevant scientific research findings represent only the initial stages of the evidence-based approach implementation and functioning. The ensuring of their effective use calls for special skills training among staff, the creation of tools and organizational mechanisms and of a facilitating organizational culture. This paper argues the need to integrate two approaches that promote the decision-making based on scientific evidence, the evidence-based approach and the use of behavioral and social sciences in the decision-making, to potentiate the contribution of the behavioral sciences to the increasing of the decision-making efficiency. The efforts made in this paper had overall objective to prepare and facilitate the use of research evidence provided by behavioral sciences in the organizational decision-making process by presenting the main concepts and knowledge in the field and by proposing an outline procedure specifically developed.

    Full Text Available Scores on the three-item Cognitive Reflection Test (CRT have been linked with dual-system theory and normative decision making (Frederick, 2005. In particular, the CRT is thought to measure monitoring of System 1 intuitions such that, if cognitive reflection is high enough, intuitive errors will be detected and the problem will be solved. However, CRT items also require numeric ability to be answered correctly and it is unclear how much numeric ability vs. cognitive reflection contributes to better decision making. In two studies, CRT responses were used to calculate Cognitive Reflection and numeric ability; a numeracy scale was also administered. Numeric ability, measured on the CRT or the numeracy scale, accounted for the CRT’s ability to predict more normative decisions (a subscale of decision-making competence, incentivized measures of impatient and risk-averse choice, and self-reported financial outcomes; Cognitive Reflection contributed no independent predictive power. Results were similar whether the two abilities were modeled (Study 1 or calculated using proportions (Studies 1 and 2. These findings demonstrate numeric ability as a robust predictor of superior decision making across multiple tasks and outcomes. They also indicate that correlations of decision performance with the CRT are insufficient evidence to implicate overriding intuitions in the decision-making biases and outcomes we examined. Numeric ability appears to be the key mechanism instead.

    Systematic reviews aide the analysis and dissemination of evidence, using rigorous and transparent methods to generate empirically attained answers to focused research questions. Identifying all evidence relevant to the research questions is an essential component, and challenge, of systematic reviews. Gray literature, or evidence not published in commercial publications, can make important contributions to a systematic review. Gray literature can include academic papers, including theses and dissertations, research and committee reports, government reports, conference papers, and ongoing research, among others. It may provide data not found within commercially published literature, providing an important forum for disseminating studies with null or negative results that might not otherwise be disseminated. Gray literature may thusly reduce publication bias, increase reviews' comprehensiveness and timeliness, and foster a balanced picture of available evidence. Gray literature's diverse formats and audiences can present a significant challenge in a systematic search for evidence. However, the benefits of including gray literature may far outweigh the cost in time and resource needed to search for it, and it is important for it to be included in a systematic review or review of evidence. A carefully thought out gray literature search strategy may be an invaluable component of a systematic review. This narrative review provides guidance about the benefits of including gray literature in a systematic review, and sources for searching through gray literature. An illustrative example of a search for evidence within gray literature sources is presented to highlight the potential contributions of such a search to a systematic review. Benefits and challenges of gray literature search methods are discussed, and recommendations made. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

    The participation of general practitioners (GPs) in primary care research is variable and often poor. We aimed to develop a substantive and empirical theoretical framework to explain GPs' decision-making process to participate in research. We used the grounded theory approach to construct a substantive theory to explain the decision-making process of GPs to participate in research activities. Five in-depth interviews and four focus group discussions were conducted among 21 GPs. Purposeful sampling followed by theoretical sampling were used to attempt saturation of the core category. Data were collected using semi-structured open-ended questions. Interviews were recorded, transcribed verbatim and checked prior to analysis. Open line-by-line coding followed by focus coding were used to arrive at a substantive theory. Memoing was used to help bring concepts to higher abstract levels. The GPs' decision to participate in research was attributed to their inner drive and appreciation for primary care research and their confidence in managing their social and research environments. The drive and appreciation for research motivated the GPs to undergo research training to enhance their research knowledge, skills and confidence. However, the critical step in the GPs' decision to participate in research was their ability to align their research agenda with priorities in their social environment, which included personal life goals, clinical practice and organisational culture. Perceived support for research, such as funding and technical expertise, facilitated the GPs' participation in research. In addition, prior experiences participating in research also influenced the GPs' confidence in taking part in future research. The key to GPs deciding to participate in research is whether the research agenda aligns with the priorities in their social environment. Therefore, research training is important, but should be included in further measures and should comply with GPs' social

  3. Addressing inequalities in health--what is the contribution of health trainers?

    White, Judy; Woodward, Jenny; South, Jane

    2013-07-01

    The role that members of the public (non-professional lay people) can play in improving health is being increasingly recognised in research and policy. This paper explores what contribution lay people employed as health trainers are making to addressing health inequalities in England. Data from eight local evaluations of health trainer services were synthesised using a data-extraction framework to find out about client populations, any lifestyle changes made, health trainers' background and community engagement activities. These data were compared with national data to assess how findings relating to addressing inequalities compared with the national picture. Local data largely matched national data and showed that health trainers are reaching people living with disadvantage and enabling them to make lifestyle changes. The data suggest that they do this by engaging with communities and taking a person-centred approach. Being non-clinical peers is also important. However, no evidence was found that health trainers were impacting on health inequalities at a population level. Health trainers are contributing to addressing health inequalities but the services evaluated were small and had been operating for a limited time, so to expect reductions in inequalities at a population level within districts would be unrealistic. The findings of this synthesis present a challenge to primary care and public health to employ health trainers in order to engage marginalised communities as one element of plans to address health inequalities.

  4. Making sense of the German Wikipedia community

    Full Text Available This article presents the findings from a qualitative study of the German Wikipedia community, focusing on how people engaged with Wikipedia make sense of norms, collaborative practices and means of regulation within the community. The study highlights the strong focus on the quality of the end-product (the encyclopedia in the German community, stressing that article quality is seen as more important than the wiki-process as such. As the community has grown, an increasing number of rules and mechanisms have been deployed to resolve various issues and conflicts, however the interviewees do not perceive Wikipedia as being bureaucratic, but rather describe it as a “rule-governed anarchy”. The findings suggest that people contribute for a variety of reasons, yet point to reactions from and interactions with fellow Wikipedians as one of the strongest motivational drivers for participation.

  5. On the extension of Importance Measures to complex components

    2015-01-01

    Importance Measures are indicators of the risk significance of the components of a system. They are widely used in various applications of Probabilistic Safety Analyses, off-line and on-line, in decision making for preventive and corrective purposes, as well as to rank components according to their contribution to the global risk. They are primarily defined for the case the support model is a coherent fault tree and failures of components are described by basic events of this fault tree. In this article, we study their extension to complex components, i.e. components whose failures are modeled by a gate rather than just a basic event. Although quite natural, such an extension has not received much attention in the literature. We show that it raises a number of problems. The Birnbaum Importance Measure and the notion of Critical States concentrate these difficulties. We present alternative solutions for the extension of these notions. We discuss their respective advantages and drawbacks. This article gives a new point of view on the mathematical foundations of Importance Measures and helps us to clarify their physical meaning. - Highlights: • We propose an extension of Importance Measures to complex components. • We define our extension in term minterms, i.e. states of the system. • We discuss the physical interpretation of Importance Measures in light of this interpretation

  6. Adolescent pediatric decision-making: a critical reconsideration in the light of the data.

    2014-12-01

    Adolescents present a puzzle. There are foundational unclarities about how they should be regarded as decision-makers. Although superficially adolescents may appear to have mature decisional capacity, their decision-making is in many ways unlike that of adults. Despite this seemingly obvious fact, a concern for the claims of autonomy has led to the development of the legal doctrine of the mature minor. This legal construct considers adolescents, as far as possible, as equivalent to adults for the purpose of medical decision-making. The movement to support independent decision-making by adolescents through providing information to them and securing their consent apart from their parents is encouraged by those legal understandings that hold that unemancipated minors should generally be considered as possessing effective decisional capacity. Such legal structures, however, do not adequately take account of the wide variations in adolescent capacities, the immaturity of most adolescent decision-makers, or the important contributions made by parents to the development of their adolescents through parental partnering in the adolescent's decision-making. The data available indicate that in general adolescents should be regarded as apprentice decision-makers who should make decisions in collaboration with their parents until at least the age of 18. Steps should not be taken pre-emptively to isolate adolescents from the guidance of their parents. As a general rule, what Piker has referred to as "collaborative paternalism" appears most likely both to protect adolescents from their own untoward choices, while also very importantly helping them with parental guidance to develop into mature decision-makers with the capacity to make medical choices on their own.

  7. Translational Models of Gambling-Related Decision-Making.

    Science.gov (United States)

    Winstanley, Catharine A; Clark, Luke

    Gambling is a harmless, recreational pastime that is ubiquitous across cultures. However, for some, gambling becomes a maladaptive and compulsive, and this syndrome is conceptualized as a behavioural addiction. Laboratory models that capture the key cognitive processes involved in gambling behaviour, and that can be translated across species, have the potential to make an important contribution to both decision neuroscience and the study of addictive disorders. The Iowa gambling task has been widely used to assess human decision-making under uncertainty, and this paradigm can be successfully modelled in rodents. Similar neurobiological processes underpin choice behaviour in humans and rats, and thus, a preference for the disadvantageous "high-risk, high-reward" options may reflect meaningful vulnerability for mental health problems. However, the choice behaviour operationalized by these tasks does not necessarily approximate the vulnerability to gambling disorder (GD) per se. We consider a number of psychological challenges that apply to modelling gambling in a translational way, and evaluate the success of the existing models. Heterogeneity in the structure of gambling games, as well as in the motivations of individuals with GD, is highlighted. The potential issues with extrapolating too directly from established animal models of drug dependency are discussed, as are the inherent difficulties in validating animal models of GD in the absence of any approved treatments for GD. Further advances in modelling the cognitive biases endemic in human decision-making, which appear to be exacerbated in GD, may be a promising line of research.

    Complex and expensive treatment options have increased the frequency and emphasis of ethical decision-making in healthcare. In order to meet these challenges effectively, we need to identify how nurses contribute the resolution of these dilemmas. To identify the values, beliefs and contextual influences that inform decision-making. To identify the contribution made by nurses in achieving the resolution of ethical dilemmas in practice. An interpretive exploratory study was undertaken, 11 registered acute care nurses working in a district general hospital in England were interviewed, using semi-structured interviews. In-depth content analysis of the data was undertaken via NVivo coding and thematic identification. Participants and context: Participants were interviewed about their contribution to the resolution of ethical dilemmas within the context of working in an acute hospital ward. Participants were recruited from all settings working with patients of any age and any diagnosis. Ethical considerations: Ethical approval was obtained from the local National Research Ethics Committee. Four major themes emerged: 'best for the patient', 'accountability', 'collaboration and conflict' and 'concern for others'. Moral distress was also evident in the literature and findings, with moral dissonance recognised and articulated by more experienced nurses. The relatively small, single-site sample may not account for the effects of organisational culture on the results; the findings suggested that professional relationships were key to resolving ethical dilemmas. Nurses use their moral reasoning based on their beliefs and values when faced with ethical dilemmas. Subsequent actions are mediated though ethical decision-making frames of reference including deontology, consequentialism, the ethics of care and virtue ethics. Nurses use these in contributing to the resolution of these dilemmas. Nurses require the skills to develop and maintain professional relationships for addressing

    Serotonin (5-HT) modulates emotional and cognitive functions such as fear conditioning (FC) and decision making. This study investigated the effects of a functional polymorphism in the regulatory region (5-HTTLPR) of the human 5-HT transporter (5-HTT) gene on observational FC, risk taking and susceptibility to framing in decision making under uncertainty, as well as multidimensional anxiety and autonomic control of the heart in healthy volunteers. The present results indicate that in comparison to the homozygotes for the long (l) version of 5-HTTLPR, the carriers of the short (s) version display enhanced observational FC, reduced financial risk taking and increased susceptibility to framing in economic decision making. We also found that s-carriers have increased trait anxiety due to threat in social evaluation, and ambiguous threat perception. In addition, s-carriers also show reduced autonomic control over the heart, and a pattern of reduced vagal tone and increased sympathetic activity in comparison to l-homozygotes. This is the first genetic study that identifies the association of a functional polymorphism in a key neurotransmitter-related gene with complex social-emotional and cognitive processes. The present set of results suggests an endophenotype of anxiety disorders, characterized by enhanced social learning of fear, impaired decision making and dysfunctional autonomic activity.

    2017-01-01

    The aim of this study was to describe systematically recent studies that show the importance of cholesterol in psychopathology. This study was a review. The following databases were searched for relevant published articles on human studies: MEDLINE, Web of Science, EBSCOhost Academic Search Complete, and Psychology and Behavioral Sciences Collection (papers from January 2012 to March 2016). Eighteen recent papers were selected, and thematic dimensions showing correlations between cholesterol and behavioral and psychopathological variables were depression, suicide, personality, and aggression. This paper demonstrates that recent research corroborates the idea that cholesterol plays an important role in governing behavior and psychopathology in humans. Deepening the studies in this field could be a promising avenue for future research, with implications for treating people with behavior or mental health problems.

    2017-01-01

    The ability of decision making plays a highly relevant role in our survival, but is adversely affected during the process of aging. The present review aims to provide a better understanding of age-related differences in decision making and the role of cognitive and emotional factors in this context. We reviewed the literature about age-effects on decision-making performance, focusing on decision making under ambiguous and objective risk. In decisions under ambiguous risks, as measured by the Iowa Gambling Task, decisions are based on the experiences with consequences. In this case, many articles have attributed age-related impairments in decision making to changes in emotional and somatic reward- and punishment processing. In decisions under objective risks, as measured for example by the Game of Dice Task, decisions can be based on explicit information about risks and consequences. In this case, age-related changes have been attributed mainly to a cognitive decline, particularly impaired executive functions. However, recent findings challenge these conclusions. The present review summarizes neuropsychological and neurophysiological findings of age-related differences in decision making under ambiguous and objective risk. In this context, the relevance of learning, but also of cognitive and emotional contributors - responsible for age-related differences in decision making - are additionally pointed out.

    Full Text Available Suppliers of goods present a very important cost object for trading companiessuch as retail. There is, however, no theoretical explanation as to how to calculate a contribution to profits generated from an individual supplier. This calculation is the subject of the paper. There is no calculation that shows how goods, provided from the supplier, create profit through gross margin and how the supplier`s behavior influences the costs (like delivery terms, costs of keeping specific goods fresh…. The final costs further decrease the profit generated by suppliers. As they have long found it illogical to calculate contribution to profit from suppliers in a production company, trading companies have long ignored it, as well. The Activity Based Costing (ABC, as the up-to-date system, still does not possess the cost hierarchy for suppliers as the cost object. The aim of the paper is to present a proposal for creating the cost hierarchy for suppliers in a trade company through creating a theoretical financial model as a method. The model also offers a theoretical explanation of how to calculate the contribution from a supplier or a group of suppliers. It is based on empirically evident activities in any supermarket or hypermarket, which makes it possible to create explanatory theoretical research.

  14. Adults' decision-making about the electronic waste issue: The role of the nature of science conceptualizations and moral concerns in socio-scientific decision-making

    Science.gov (United States)

    Yu, Yuqing

    Socio-scientific issues have become increasingly important in Science-Technology-Society (STS) education as a means to make science learning more relevant to students' lives. This study used the e-waste issue as a context to investigate two aspects of socio-scientific decision-making: (1) the relationship between the nature of science (NOS) conceptualizations and decision-making; and (2) moral concerns involved in the process of decision-making. This study contributes to the field of socio-scientific issue research and STS education in the following ways. First, it is the first study that performed meta-analysis to seek the relationship between the NOS understanding and decision-making. This study concludes that valuable NOS conceptualizations that are highly related to the socio-scientific issue under investigation, rather than general NOS understanding, exert statistically significant influences on decision-making. Second, this study empirically examined the Multiple Responses Model (MRM), which enables the transfer of qualitative NOS responses into quantitative data, and hence, inferential statistics. The current study justifies the significance of unidimensionality to the application of the MRM. It addresses the limitations associated with the MRM and provides implications for future use of the MRM in other contexts. Finally, the study explores the role of moral concerns in socio-scientific decision-making. Eight participants engaged in interviews that were designed to elicit their reactions and feelings regarding the issue of exporting e-waste to poor countries. Qualitative analyses demonstrated that moral considerations were significant influences on decision-making. In addition, participants' action responses revealed that they were motivated to take action to help the environment. The study has implications for socio-scientific issue studies in other contexts and for teacher education programs that use socio-scientific issues to advance teachers' reasoning

    Full Text Available The importance-performance grid is a marketing instrument used to make decisions regarding the growth of the consumers’ satisfaction, by optimizing the attributes of products. This grid is a useful instrument, as it is shown in the paper, to the extent to which the importance and performance of the attributes are correctly recorded. Another idea underlined in the paper is that regarding the difficulty to directly determine the importance of attributes or in the same stage with the determination of the service performance, according to these attributes. The objectives of this paper are to analyze the importance-performance grid (suggested by Martilla and amended by Abalo,through an empirical study in the field of tourist services used and to test the conditions to carry out this grid taking into account the hypothetical case of indirectly determining the importance of the quality attributes. The literature in the field regarding the importance-performance analysis is analysed and the subsequent amendments to the previous grid suggested by Martilla and James in 1977. The present paper is a continuation of several studies on the same subject, in which the following research methods were used: direct survey by questionnaire, the Spearman correlation coefficient, and the entropy calculus. A comparative analysis of the importance-performance grid if directly recording the importance of attributes (through survey by questionnaire and of the indirect determination of the importance of the attributes (through the Spearman coefficient and entropy calculus is being suggested. The results indicate possible uses of methods, yet it raises a series of collateral problems regarding their application. The contribution of this paper is given by the suggestion of two methods to indirectly determine the importance of attributes, which take into account the data measurement scale used and the collinearity among attributes and which lead to pertinent results

  20. Evidence that global evapotranspiration makes a substantial contribution to the global atmospheric temperature slowdown

    Science.gov (United States)

    Leggett, L. Mark W.; Ball, David A.

    2018-02-01

    The difference between the time series trend for temperature expected from the increasing level of atmospheric CO2 and that for the (more slowly rising) observed temperature has been termed the global surface temperature slowdown. In this paper, we characterise the single time series made from the subtraction of these two time series as the `global surface temperature gap'. We also develop an analogous atmospheric CO2 gap series from the difference between the level of CO2 and first-difference CO2 (that is, the change in CO2 from one period to the next). This paper provides three further pieces of evidence concerning the global surface temperature slowdown. First, we find that the present size of both the global surface temperature gap and the CO2 gap is unprecedented over a period starting at least as far back as the 1860s. Second, ARDL and Granger causality analyses involving the global surface temperature gap against the major candidate physical drivers of the ocean heat sink and biosphere evapotranspiration are conducted. In each case where ocean heat data was available, it was significant in the models: however, evapotranspiration, or its argued surrogate precipitation, also remained significant in the models alongside ocean heat. In terms of relative scale, the standardised regression coefficient for evapotranspiration was repeatedly of the same order of magnitude as—typically as much as half that for—ocean heat. The foregoing is evidence that, alongside the ocean heat sink, evapotranspiration is also likely to be making a substantial contribution to the global atmospheric temperature outcome. Third, there is evidence that both the ocean heat sink and the evapotranspiration process might be able to continue into the future to keep the temperature lower than the level-of-CO2 models would suggest. It is shown that this means there can be benefit in using the first-difference CO2 to temperature relationship shown in Leggett and Ball (Atmos Chem Phys 15

    Shared decision-making involves the participation of patient and dental practitioner. Well-informed decision-making requires that both parties understand important concepts that may influence the decision. This fourth article in a series of 4 aims to discuss the importance of patients' values when a clinical decision is made. We report on how to incorporate important concepts for well-informed, shared decision-making. Here, we present patient values as an important issue, in addition to previously established topics such as the risk of bias of a study, cost-effectiveness of treatment approaches, and a comparison of therapeutic benefit with potential side effects. We provide 2 clinical examples and suggestions for a decision tree, based on the available evidence. The information reported in this article may improve the relationship between patient and dental practitioner, resulting in more well-informed clinical decisions. Copyright © 2017 Elsevier Inc.

    Full Text Available Despite global recognition of the importance of human resources for health (HRH in achieving health system goals, very little is known about what works, for whom and under what circumstances, especially for low-income and middleincome countries. Several important events and reports have called for increased funding and capacity for HRH research in recent years and several initiatives have started as a result. Progress has been slow, however. The following strategies can be most valuable in ensuring the relevance of the generated evidence for decision making and its contribution to stronger health systems. The first is to promote national processes to set priorities for HRH research with active participation from decision makers. The second is to make conscious efforts to scale up primary research to address priority questions and to develop sustainable mechanisms to evaluate the impact of current or new HRH strategies to feed into the policy making process. The third is to invest in the development of systematic reviews to synthesize available evidence and in the adaptation of the underlying methods to make them more responsive to the type of questions and the nature of research involving HRH issues. The fourth and most important is to consistently use a systems approach in framing and addressing research questions. While a narrow approach may be more attractive and simple, health systems and the problems facing them are not. Increasing the body of evidence that takes into account the complexity of health systems, and particularly human resources for health, will advance knowledge in this area and will make big strides in the quality and usefulness of the generated evidence.

  4. Presence of polybrominated diphenyl ethers in Spanish sewage sludges. Important contribution of deca-BDE

    Introduction Polybrominated diphenyl ethers (PBDE) are a family of synthetic chemicals widely used in industry to delay, inhibit or even suppress combustion process in manufactured items. Flame retardant products are frequently added into plastic, electronic, paint and textile materials to reduce the risk of ignition. During last years, increasing levels of PBDE have been detected in the environment, suggesting release from the treated surface as main pathway for environmental intake. Their physicochemical structure make them substances of highly lypophylic, bioaccumulative and persistent nature, with potential toxic effects observed onto wildlife and humans. Some European countries (Switzerland and Sweden) have promoted strategies to enlarge the knowledge of PBDE, in particular their occurrence and levels on sewage sludge. Observations point domestic washing of garment/clothes and industrial discharges from plastic and textile manufacture industry as major sources of contamination. First European results from 1988 revealed levels of about 20-30 {mu}g/kg dw of PBDEs (BDEs 47, 99 and 100) in sludge samples collected in Sweden. More recently, another Swedish survey conducted on three waste-water treatment facilities pointed levels of PBDE (BDE 47, 99 and 209) of about 200 ng/g dw, along with minor contribution of other contaminants such as TBBPA and HBCD iv. Few studies have been carried out in US. Hale et al. compared levels of Tetra-, PentaBDE (BDE 47, BDE 99 and BDE 100) and DecaBDE 209 congeners in sludge from different US locations. Values ranged from 1000 to 2290 {mu}g/kg dw (Tri- to HexaBDE) and from 84 to 4890 {mu}g/kg dw for DecaBDE 209, with mean values of about 1600 and 1000 {mu}g/kg dw, respectively. In general, concentrations of BDE 47, 99, 100 and 209 exceeded those of the major PCB congeners and other halogenated contaminants also found in the sludge. Following this trend, this work aims a preliminary assessment of selected PBDE congener levels on

    2009-05-01

    Many models of judgment and decision-making posit distinct cognitive and emotional contributions to decision-making under uncertainty. Cognitive processes typically involve exact computations according to a cost-benefit calculus, whereas emotional processes typically involve approximate, heuristic processes that deliver rapid evaluations without mental effort. However, it remains largely unknown what specific parameters of uncertain decision the brain encodes, the extent to which these parameters correspond to various decision-making frameworks, and their correspondence to emotional and rational processes. Here, I review research suggesting that emotional processes encode in a precise quantitative manner the basic parameters of financial decision theory, indicating a reorientation of emotional and cognitive contributions to risky choice.

    Nuclear weapons make possible the ultimate epidemic. Since their use would lead to human and material damage orders of magnitude more extensive than anything ever known, and since the medical community would be impotent to respond in any meaningful way, all efforts must be directed to the prevention of nuclear war. By ensuring that the medical realities are known to decision-makers and the people of the world, the medical community can help focus attention on the critical need for an effective prescription for prevention and thereby can contribute in an important fashion to national security

    Protecting the environment and enhancing food security are among the world's Sustainable Development Goals and greatest challenges. International food trade is an important mechanism to enhance food security worldwide. Nonetheless, it is widely concluded that in international food trade importing countries gain environmental benefits, while exporting countries suffer environmental problems by using land and other resources to produce food for exports. Our study shows that international food trade can also lead to environmental pollution in importing countries. At the global level, our metaanalysis indicates that there was increased nitrogen (N) pollution after much farmland for domestically cultivated N-fixing soybeans in importing countries was converted to grow high N-demanding crops (wheat, corn, rice, and vegetables). The findings were further verified by an intensive study at the regional level in China, the largest soybean-importing country, where the conversion of soybean lands to corn fields and rice paddies has also led to N pollution. Our study provides a sharp contrast to the conventional wisdom that only exports contribute substantially to environmental woes. Our results suggest the need to evaluate environmental consequences of international trade of all other major goods and products in all importing countries, which have significant implications for fundamental rethinking in global policy-making and debates on environmental responsibilities among consumers, producers, and traders across the world.

  8. Application of a new importance measure for parametric uncertainty in PSA

    International Nuclear Information System (INIS)

    Poern, K.

    1997-04-01

    The traditional approach to uncertainty analysis in PSA, with propagation of basic event uncertainties through the PSA model, generates as an end product the uncertainty distribution of the top event frequency. This distribution, however, is not of much value for the decision maker. Most decisions are made under uncertainty. What the decision maker needs, to enhance the decision-making quality, is an adequate uncertainty importance measure that provides the decision maker with an indication of on what basic parameters it would be most valuable - as to the quality of the decision making in the specific situation - to procure more information. This paper will describe an application of a new measure of uncertainty importance that has been developed in the ongoing joint Nordic project NKS/RAK-1:3. The measure is called ''decision oriented'' because it is defined within a decision theoretic framework. It is defined as the expected value of a certain additional information about each basic parameter, and utilizes both the system structure and the complete uncertainty distributions of the basic parameters. The measure provides the analyst and the decision maker with a diagnostic information pointing to parameters on which more information would be most valuable to procure in order to enhance the decision-making quality. This uncertainty importance measure must not be confused with the more well-known, traditional importance measures of various kinds that are used to depict the contributions of each basic event or parameter (represented by point values) to the top event frequency. In this study the new measure is practically demonstrated through a real application on the top event: Water overflow through steam generator safety valves caused by steam generator tube rupture. This application object is one of the event sequences that the fore mentioned Nordic project has analysed with an integrated approach. The project has been funded by the Swedish Nuclear Power

  9. The contribution of technology to added value

    Fernandes, António S C

    2013-01-01

    There is a wide consensus that introduction of technology to the production process contributes to an overall economic value, however, confusion between technology, knowledge and capital often makes value calculations ambiguous and non-objective. The Contribution of Technology to Added Value addresses not only this issue of definition but also provides a production model to assess the value contribution of technology within the production process. A clarification  of fundamental semantics  provides a significant taxonomy for technology dependence, and allows understanding and modeling of how knowledge, technology and capital individually contribute to production and to value adding. A new technology dependence taxonomy is proposed and assessed following chapters explaining growth models, the KTC model and technology index values. Balancing theoretical knowledge with real-world data and applications The Contribution of Technology to Added Value clarifies the issue of value adding for a range of different vie...

    Human choice behaviors during social interactions often deviate from the predictions of game theory. This might arise partly from the limitations in the cognitive abilities necessary for recursive reasoning about the behaviors of others. In addition, during iterative social interactions, choices might change dynamically as knowledge about the intentions of others and estimates for choice outcomes are incrementally updated via reinforcement learning. Some of the brain circuits utilized during social decision making might be general-purpose and contribute to isomorphic individual and social decision making. By contrast, regions in the medial prefrontal cortex (mPFC) and temporal parietal junction (TPJ) might be recruited for cognitive processes unique to social decision making.

  12. Smoking cessation programmes in radon affected areas: can they make a significant contribution to reducing radon-induced lung cancers?

    Domestic radon levels in parts of the UK are sufficiently high to increase the risk of lung cancer in the occupants. Public health campaigns in Northamptonshire, a designated radon affected area with 6.3% of homes having average radon levels over the UK action level of 200 Bq m -3 , have encouraged householders to test for radon and then to carry out remediation in their homes, but have been only partially successful. Only 40% of Northamptonshire houses have been tested, and only 15% of householders finding raised levels proceed to remediate. Of those who did remediate, only 9% smoked, compared to a countywide average of 28.8%. This is unfortunate, since radon and smoking combine to place the individual at higher risk by a factor of around 4, and suggests that current strategies to reduce domestic radon exposure are not reaching those most at risk. During 2004-5, the NHS Stop Smoking Services in Northamptonshire assisted 2,808 smokers to quit to the 4-week stage, with some 30% of 4-week quitters remaining quitters at 1 year. We consider whether smoking cessation campaigns make significant contributions to radon risk reduction on their own, by assessing individual occupants' risk of developing lung cancer from knowledge of their age, gender, and smoking habits, together with he radon level in their house. The results demonstrate that smoking cessation programmes have significant added value in radon affected areas, and contribute a greater health benefit than reducing radon levels in the smokers' homes, whilst they remain smokers. Additionally, results are presented from a questionnaire-based survey of quitters, addressing their reasons for seeking help in quitting smoking, and whether knowledge of radon risks influenced this decision. The impact of these findings on future public health campaigns to reduce the impact of radon and smoking are discussed. (author)

  13. Narrative Interest Standard: A Novel Approach to Surrogate Decision-Making for People With Dementia.

    Science.gov (United States)

    Wilkins, James M

    2017-06-17

    Dementia is a common neurodegenerative process that can significantly impair decision-making capacity as the disease progresses. When a person is found to lack capacity to make a decision, a surrogate decision-maker is generally sought to aid in decision-making. Typical bases for surrogate decision-making include the substituted judgment standard and the best interest standard. Given the heterogeneous and progressive course of dementia, however, these standards for surrogate decision-making are often insufficient in providing guidance for the decision-making for a person with dementia, escalating the likelihood of conflict in these decisions. In this article, the narrative interest standard is presented as a novel and more appropriate approach to surrogate decision-making for people with dementia. Through case presentation and ethical analysis, the standard mechanisms for surrogate decision-making for people with dementia are reviewed and critiqued. The narrative interest standard is then introduced and discussed as a dementia-specific model for surrogate decision-making. Through incorporation of elements of a best interest standard in focusing on the current benefit-burden ratio and elements of narrative to provide context, history, and flexibility for values and preferences that may change over time, the narrative interest standard allows for elaboration of an enriched context for surrogate decision-making for people with dementia. More importantly, however, a narrative approach encourages the direct contribution from people with dementia in authoring the story of what matters to them in their lives.

  15. Making and Changing Wills

    2016-02-01

    Full Text Available Wills are important social, economic, and legal documents. Yet little is known about current will making practices and intentions. A comprehensive national database on the prevalence of will making in Australia was developed to identify who is or is not most likely to draw up a will and triggers for making and changing wills. A national survey of 2,405 adults aged above 18 years was administered by telephone in August and September 2012. Fifty-nine percent of the Australian adult population has a valid will, and the likelihood of will making increases with age and estate value. Efforts to get organized, especially in combination with life stage and asset changes trigger will making; procrastination, rather than a strong resistance, appears to explain not making a will. Understanding will making is timely in the context of predicted significant intergenerational transfers of wealth, changing demographics, and a renewed emphasis on retirement planning.

  19. Why is it hard to make progress in assessing children's decision-making competence?

    For decades, the discussion on children's competence to consent to medical issues has concentrated around normative concerns, with little progress in clinical practices. Decision-making competence is an important condition in the informed consent model. In pediatrics, clinicians need to strike a proper balance in order to both protect children's interests when they are not fully able to do so themselves and to respect their autonomy when they are. Children's competence to consent, however, is currently not assessed in a standardized way. Moreover, the correlation between competence to give informed consent and age in children has never been systematically investigated, nor do we know which factors exactly contribute to children's competence.This article aims at identifying these gaps in knowledge and suggests options for dealing with the obstacles in empirical research in order to advance policies and practices regarding children's medical decision-making competence. Understanding children's competency is hampered by the law. Legislative regulations concerning competency are established on a strong presumption that persons older than a certain age are competent, whereas younger persons are not. Furthermore, a number of contextual factors are believed to be of influence on a child's decision-making competence: the developmental stage of children, the influence of parents and peers, the quality of information provision, life experience, the type of medical decision, and so on. Ostensibly, these diverse and extensive barriers hinder any form of advancement in this conflicted area. Addressing these obstacles encourages the discussion on children's competency, in which the most prominent question concerns the lack of a clear operationalization of children's competence to consent. Empirical data are needed to substantiate the discussion. The empirical approach offers an opportunity to give direction to the debate. Recommendations for future research include: studying a

    1999-12-01

    From data obtained in this study, the weak or negligible influences on the quality of worklife of OR nurses are: Organizational Structure Leadership, and Organizational Learning. Things that matter to OR nurses and that influence their quality of worklife are: Collaborative Decision-Making, Multiskilled Workers, Change, Organizational Culture, Locus of Control; and the most important influence of all- Teamwork. So, now when the question is asked "What Makes Your Day?" The answer is clear--at the end of the day, it all boils down to the most fundamental of all answers--People! People are involved in collaborative decision-making, multiskilled workers, change, organizational culture, locus of control, and teamwork. These People include the OR nurse, who is involved in collaborative decision-making and all the other items that affect your daily work environment. The people you collaborate with, the people you interact with in the organization, and the people that make up the team--you and everyone around you are responsible for that magic ingredient--Teamwork. What you say, what you do, and how you behave makes all the difference in the daily worklife of your colleagues. Each and every comment and interaction contributes to the efficiency and effectiveness of the team. Each and every day from this day forward, remember this--remember how important your role is in building a strong and effective team. At the recent AORN Congress, Joan Rivers shared a favourite saying with us: "The past is history, The future a mystery, Today is a gift from God, that is why it is called the present." Today is all that we really have--let us make the best of each and every day as we continue to respect and value each member of the team. Teamwork--our building block of the future--yours, mine, and every other member of the surgical team. Each member can make an enormous contribution--we only need to believe that the "best is yet to be--the best resides in me". Yes, we can do our part in

    Nonresidential fathers are challenged to remain involved with their children across time in both direct and indirect ways, including influencing decision-making around important issues such as school attendance and medical care. An analytic sample of 1,350 families with residential mothers and nonresidential fathers was selected from the Early Childhood Longitudinal Survey-Birth Cohort (ECLS-B) to examine the longitudinal relationships between mothers' reports of nonresidential fathers' influence in decision-making and their provision of resources to their children. Findings indicate that fathers' voluntary contribution of tangible resources (informal child support, caregiving time) when children are 2 years old positively predict fathers' influence in decision-making regarding the care of their 4-year-old children. Fathers' early formal child support is not related to later decision-making. Fathers' communication with mother about the child at 24 months is related to later decision-making among daughters but not sons. Fathers' early decision-making is longitudinally related to later informal child support, caregiving time, and coparenting communication. The findings support the utility of a resource theory of fathering for understanding and predicting observed patterns of father involvement.

    Directory of Open Access Journals (Sweden)

    Antonio Giulio de Belvis

    2011-12-01

    Full Text Available Background: The Italian Observatory Healthcare Report (IOHR - 8th edition [1] aims to help policy makers in the process of decision making through a set of validated indicators resulting from the multidisciplinary activity of several public health experts. Its main task is to gather comparable data on the health status and the quality of health care services throughout the Italian regions. Methods: The report adopts a European approach in order to build a benchmarking activity and the selection criteria of indicators include: meaning, feasibility and quality, comparability and reliability. Each indicator is analyzed by experts in terms of meaning, pattern, validity and limits, graphic representation; recommendations are included for decision makers. A peer reviewing is performed for quality assessment. Results: The IOHR 2010 included 96 indicators, analysed by 203 authors. Through comparable regional data coming from different sources, an overview of the Italian Health System, and a gauging of the impact that different regional organizational and institutional arrangements have on the quality of health services, have been provided. Though data analysis showed a North-South gradient in the quality and the organization of health care services, nevertheless, the overall health status of Italian population is good. Risk factors, lifestyles and prevention together with geographical and social differences in health status and service access are the main priorities. Conclusions: The IOHR helps monitoring the health status in the Italian regions through specific indicators characterized by scientific strictness. It contributes to identifying the situations of excellence and disseminating public health care control tools in order to facilitate the decision making process.

    Understanding the preferences of patients with multiple sclerosis (MS) for disease-modifying drugs and involving these patients in clinical decision making can improve the concordance between medical decisions and patient values and may, subsequently, improve adherence to disease-modifying drugs. This study aims first to identify which characteristics-or attributes-of disease-modifying drugs influence patients´ decisions about these treatments and second to quantify the attributes' relative importance among patients. First, three focus groups of relapsing-remitting MS patients were formed to compile a preliminary list of attributes using a nominal group technique. Based on this qualitative research, a survey with several choice tasks (best-worst scaling) was developed to prioritize attributes, asking a larger patient group to choose the most and least important attributes. The attributes' mean relative importance scores (RIS) were calculated. Nineteen patients reported 34 attributes during the focus groups and 185 patients evaluated the importance of the attributes in the survey. The effect on disease progression received the highest RIS (RIS = 9.64, 95% confidence interval: [9.48-9.81]), followed by quality of life (RIS = 9.21 [9.00-9.42]), relapse rate (RIS = 7.76 [7.39-8.13]), severity of side effects (RIS = 7.63 [7.33-7.94]) and relapse severity (RIS = 7.39 [7.06-7.73]). Subgroup analyses showed heterogeneity in preference of patients. For example, side effect-related attributes were statistically more important for patients who had no experience in using disease-modifying drugs compared to experienced patients (p decision making would be needed and requires eliciting individual preferences.

    Full Text Available This paper compares a number of theoretical models of decision-making with the way in which senior managers make decisions in practice. Six prominent decision-makers were interviewed about their own decision-making style, as well as their use of decision support technology. Significant variation was found in personal decision-making styles. However, some central themes emerged, such as the importance of sensitivity to the decision-making context, attention to the presentation of information, and the use of intuition. In terms of the use of decision support technology, the use of self-help tools, such as office software, was clearly favoured.

    The problems of racism and racially-motivated violence in predominantly African American communities in the US are complex, multifactorial and historically rooted. While these problems are also deeply morally troubling, bioethicists have not contributed substantially to addressing them. Concern for justice has been one of the core commitments of bioethics. For this and other reasons, bioethicists should contribute to addressing these problems. We consider how bioethicists can offer meaningful contributions to the public discourse, research, teaching, training, policy development and academic scholarship in response to the alarming and persistent patterns of racism and implicit biases associated with it. To make any useful contribution, bioethicists will require preparation and should expect to play a significant role through collaborative action with others. PMID:26982911

A clinical example is presented of a patient who, partly due to anxiety and fear, wants to opt out of further evaluation of his hematuria while the physician believes that the patient must follow up on the finding of hematuria. As patients struggle in making decisions about their medical care, physician interactions can become strained and medical care may become compromised. Physicians sometimes rely on their authority within the doctor-patient relationship to assist patients in making decisions. These methods may be ineffective when there is a conflict in motivations or goals, such as with patient ambivalence and resistance. Furthermore, the values of patient autonomy may conflict with the values of beneficence. A patient simulation exercise is used to demonstrate the value of MI in addressing the motivations of a medical patient when autonomy is difficult to realize because of a high level of resistance to change due to fear. The salience of MI in supporting the value of patient autonomy without giving up the value of beneficence is discussed by providing a method of evaluating the patient's best interests by psychotherapeutically addressing his anxious, fear-based ambivalence.

  8. Climate impacts from import of waste fuels; Klimatpaaverkan fraan import av braennbart avfall

    Imports of combustible waste has increased in recent years and imported waste has become an increasingly important fuel in the Swedish district heating systems. The projections for the next few years show that the imports can be much higher, partly due to reduced amounts of waste in the wake of economic downturn the world economy, partly because several new incinerators will be put into operation. In a environmental perspective, imports are controversial and it has been proposed that imports should be restricted. This report provides an assessment of the climate impact of importing waste for combustion. The report shows that greenhouse gas emissions due to imports of waste to the Swedish district heating plants in 2007 was reduced by 500 000 tonnes of carbon dioxide. This is equivalent to the emissions from 300 000 Swedes car journeys a year, or 2.5% of the total emission reduction target set by the Government for the non-trading sector until 2020. Imports of wood waste-chips accounts for the largest reduction, but the study shows that imports of other types of waste contribute to a reduction in emissions of greenhouse gases. The reasons for the reduction is that the use of imported waste fuel substitute for other heating and electricity generation, which gives the consequence that emissions are avoided. The largest emission reductions are obtained, however, by the importation of household waste by replacing the alternative waste treatment of the corresponding waste in the country of origin. In the countries from which imports of waste currently takes place there is a lack of treatment capacity for organic waste. The alternative treatment available is primarily deposition. This treatment causes significant emissions of methane, which is a very strong greenhouse gas. The shipment of waste that occur as a result of imports gives a marginal contribution of greenhouse gases, compared against the emission reductions outlined above

    Comparative effectiveness research (CER) is supported by policymakers as a way to provide service providers and patients with evidence-based information to make better health-care decisions and ultimately improve services for patients. However, Latina/o patients are rarely involved as study advisors, and there is a lack of documentation on how their voices contribute to the research process when they are included as collaborators. The purpose of this article was to contribute to the literature by presenting concrete contributions of Latina/o parent involvement to study design, implementation and outcomes in the context of a CER study called Padres Efectivos (Parent Activation). Researchers facilitated a collaborative relationship with parents by establishing a mentor parent group. The contributions of parent involvement in the following stages of the research process are described: (i) proposal development, (ii) implementation of protocols, (iii) analysis plan and (iv) dissemination of results. Mentor parents' contributions helped tailor the content of the intervention to their needs during proposal, increased recruitment, validated the main outcome measure and added two important outcome measures, emphasized the importance of controlling for novice treatment status and developed innovative dissemination strategies. Mentor parents' guidance to the researchers has contributed to reaching recruitment goals, strengthened the study protocol, expanded findings, supported broad ownership of study implications and enriched the overall study data collection efforts. These findings can inform future research efforts seeking an active Latino parent collaboration and the timely incorporation of parent voices in each phase of the research process. © 2017 The Authors Health Expectations Published by John Wiley & Sons Ltd.

The aims of this study were to: 1 describe PA levels of girls enrolled in dance classes, 2 determine the contribution of dance classes to total moderate-to-vigorous physical activity (MVPA, and 3 compare PA between days with a dance class (program days and days without a dance class (non-program days. Methods Participants were 149 girls (11-18 years enrolled in dance classes in 11 dance studios. Overall PA was assessed with accelerometry for 8 consecutive days, and girls reported when they attended dance classes during those days. The percent contribution of dance classes to total MVPA was calculated, and data were reduced to compare PA on program days to non-program days. Data were analyzed using mixed models, adjusting for total monitoring time. Results Girls engaged in 25.0 ± 0.9 minutes/day of MVPA. Dance classes contributed 28.7% (95% CI: 25.9%-31.6% to girls' total MVPA. Girls accumulated more MVPA on program (28.7 ± 1.4 minutes/day than non-program days (16.4 ± 1.5 minutes/day (p Conclusions Dance classes contributed a substantial proportion (29% to girls' total MVPA, and girls accumulated 70% more MVPA and 8% less sedentary behavior on program days than on non-program days. Dance classes can make an important contribution to girls' total physical activity.

    Full Text Available This article contributes to a critical assessment of the concept of democracy and consensus decision-making of the Bemba matrilineal governance system as a basis for a democratic model of engagement in African politics from an African theological perspective. It is of the opinion that assessing the concept of democracy by consensus decision-making of the Bemba provides a dialogue between the African traditional governance systems as a viable form of political governance ideal for multi-ethnic countries such as Zambia. This is a pinnacle of the 21st century debate which elaborates the important task of African Christian Theology in the rehabilitation, or renovation process of politics of identity for an authentic governance system with authentic African flavour for African governance systems.

    Full Text Available The ability of decision making plays a highly relevant role in our survival, but is adversely affected during the process of aging. The present review aims to provide a better understanding of age-related differences in decision making and the role of cognitive and emotional factors in this context. We reviewed the literature about age-effects on decision-making performance, focusing on decision making under ambiguous and objective risk. In decisions under ambiguous risks, as measured by the Iowa Gambling Task, decisions are based on the experiences with consequences. In this case, many articles have attributed age-related impairments in decision making to changes in emotional and somatic reward- and punishment processing. In decisions under objective risks, as measured for example by the Game of Dice Task, decisions can be based on explicit information about risks and consequences. In this case, age-related changes have been attributed mainly to a cognitive decline, particularly impaired executive functions. However, recent findings challenge these conclusions. The present review summarizes neuropsychological and neurophysiological findings of age-related differences in decision making under ambiguous and objective risk. In this context, the relevance of learning, but also of cognitive and emotional contributors – responsible for age-related differences in decision making – are additionally pointed out.

  19. Species contributions to single biodiversity values under-estimate whole community contribution to a wider range of values to society.

    2018-05-03

    A major task for decision makers is deciding how to consider monetary, cultural and conservation values of biodiversity explicitly when planning sustainable land use. Thus, there is a great need to understand just what "valuing" biodiversity or species really means, e.g. regarding how many and which species are important in providing ecosystem services or other values. Constructing ecosystem-level indices, however, requires weighting the relative contribution of species to the different values. Using farmland birds, we illustrate how species contribute to different biodiversity values, namely utilitarian (pest seed predation potential), cultural (species occurrence in poetry), conservational (declines and rarity) and inherent (all species equal) value. Major contributions to each value are often made by a subset of the community and different species are important for different values, leading to no correlations or, in some cases, negative correlations between species' relative contributions to different values. Our results and methods using relative contributions of species to biodiversity values can aid decisions when weighing different values in policies and strategies for natural resource management. We conclude that acknowledging the importance of the range of biodiversity values that are apparent from different perspectives is critical if the full value of biodiversity to society is to be realised.

  20. Final disposal of spent nuclear fuel in Sweden: The evolving role for KASAM when society is preparing for important decisions

    2006-01-01

    KASAM, the Swedish National Council for Nuclear Waste, is an independent scientific council attached to the Ministry of Sustainable Development. The members of KASAM are independent scientists within a wide range of areas of importance for the final disposal of radioactive waste, not only within technology and natural sciences but also within areas such as ethics and social sciences. Swedish nuclear waste management policy and implementation is currently in a protracted phase of planning and decisions. Starting in 2006 , the Swedish Nuclear Waste Management Co (SKB) is expected to submit the necessary applications for permits to construct an encapsulation facility and a disposal facility for spent nuclear fuel (in crystalline bedrock about 500 meters below the ground). According to Swedish legislation, basic permits have to be granted by the Government, but the Government will not grant such permits unless the concerned host municipality accepts the proposal. The Government decision will form the basis for detailed licensing decisions by the regulatory authorities. KASAM has an important role as an independent advisory body to the Ministry of Sustainable Development. Also, KASAM will continue its function of creating forums for dialogue that could contribute to increase knowledge and understanding and improve the knowledge base for decision-making. There are a number of questions that are relevant. Examples are: Will society have a satisfactory basis for decision-making? What happens if society is not capable of making necessary decisions? Does the decision-making process enable society to postpone important decisions if more time is needed, to avoid obstacles if they appear, and - if needed - reverse decisions? Considering issues like this, KASAM has set up a plan for its activities in the next few years. These activities are meant to contribute to the ability of society as a whole to arrive at a well-founded decision that is widely accepted. Based on facts

    2014-05-01

    Here we present a geohazards education and engagement project in the Indian region of Ladakh, used as an opportunity to train geoscience students in a number of important ethical, cultural and professional considerations. Located in the Indian Himalaya, Ladakh is home to historically-disadvantaged and endangered indigenous groups. It is also an area of extreme topography, climate and vulnerability, with a growing tourist industry. This combination of factors makes it an important region to improve geohazards understanding and observe the complex interactions between nature, society, and culture. Specific aims of this project are to (i) support community education through an interactive natural hazards programme (delivered in conjunction with a range of partners), training school-aged students from multiple socio-economic backgrounds; and (ii) increase the effectiveness of disaster risk reduction programmes, through research into the perception of natural hazards and environmental change. At all stages of this work, we are seeking to engage young geoscientists, helping them to better understand the skills and knowledge-base required to make a long-term, effective contribution to interdisciplinary research and professional practice. Through presenting an overview of this project and associated opportunities, we seek to emphasise the importance of developing practical opportunities for students to consider aspects of geoethics, social responsibility and cross-cultural understanding.

    Access to knowledge has become a cornerstone of progress for individuals and for nations. Internet as a cost-effective channel for the dissemination of knowledge and services is a paramount in our days. High-speed (broadband) Internet access can contribute to economic growth and is increasingly being recognized as a policy objective in most countries. It has been accepted that information and communication technologies (ICT) create basic infrastructure, as necessary to economic and social development as postal services, banks, medical centres and schools. However, in 48 of 71 developing countries, only less than 1 per cent of enterprises had broadband Internet connection, according to the UN Information Economy Report 2006. In the past, voice telephony has been the main option for rural and remote areas. Today, e-mail, e-commerce, tele-education, tele-health, and tele-medicine, multimedia services have become as important as the voice connectivity, maybe even more important. Training has been identified as a fundamental factor for the sustainability of ICT development and ICTP has been playing a leading role here, in collaboration with other entities. Without any doubts, universities and research centres are the most appropriate places to start the development and to disseminate knowledge necessary to assure sustainable access to the global information infrastructures in rural areas. It is hoped that ICTP's assistance will continue to contribute to foster the necessary local capacities in this field. In addition to the development of human resources and the dissemination of low-cost technology, scientists from Developing Counties need to make their voices heard in the policy, regulatory and business circles and the ICTP Associates have a role to play here.

    Mannose for mammalian glycan biosynthesis can be imported directly from the medium, derived from glucose or salvaged from endogenous or external glycans. All pathways must generate mannose 6-phosphate, the activated form of mannose. Imported or salvaged mannose is directly phosphorylated by hexokinase, whereas fructose 6-phosphate from glucose is converted to mannose 6-phosphate by phosphomannose isomerase (PMI). Normally, PMI provides the majority of mannose for glycan synthesis. To assess the contribution of PMI-independent pathways, we used PMI-null fibroblasts to study N-glycosylation of DNase I, a highly sensitive indicator protein. In PMI-null cells, imported mannose and salvaged mannose make a significant contribution to N-glycosylation. When these cells were grown in mannose-free medium along with the mannosidase inhibitor, swainsonine, to block the salvage pathways, N-glycosylation of DNase I was almost completely eliminated. Adding approximately 13 microm mannose to the medium completely restored normal glycosylation. Treatment with bafilomycin A(1), an inhibitor of lysosomal acidification, also markedly reduced N-glycosylation of DNase I, but in this case only 8 microm mannose was required to restore full glycosylation, indicating that a nonlysosomal source of mannose made a significant contribution. Glycosylation levels were greatly also reduced in glycoconjugate-free medium, when endosomal membrane trafficking was blocked by expression of a mutant SKD1. From these data, we conclude that PMI-null cells can salvage mannose from both endogenous and external glycoconjugates via lysosomal and nonlysosomal degradation pathways.

    The increasing mobility of media has in recent years led some scholars to argue for a decline in the significance of place in relation to media. This chapter argues for the importance of understanding media as vitally emplaced in the phenomenological world and it uses violent conflict to develop...... this point. Drawing on ethnographic fieldwork with information activists and journalists during the Egyptian uprising, this chapter contests understandings of media as doubling or making place insignificant. Rather, it develops an understanding of media as place-making to allow for an analysis...... of the entanglements of people and things related to media, showing how media are emplaced in the phenomenological world in the same way that violence is. Doing so, the chapter sheds light on how media can contribute to opening up places to other places and thus influence movements of people and things in conflict....

    This document first proposes the White Paper prepared for the experts' conference. After a presentation of the Emission Trading System (ETS), this paper highlights the benefit of the introduction of economical instruments rather than regulatory instruments to promote the reduction of greenhouse gas emissions. It underlines the distinction between the proposed 'climate-energy contribution' (or carbon tax) and the Cambridge tax. Then, it describes how to implement such a contribution, i.e. how to define its base, and how to relate it with existing taxes. Some graphs compare the tax rates on fuels, gas and domestic oil in European countries. The paper then defines what the field of application of the contribution could be, how to make this contribution more efficient, and what could be its economical consequences. Then, the document proposes the text of Michel Rocard's intervention on the stakes of conference on this climate-energy contribution

    Chronic marijuana use has been associated with impairments of learning, memory, and executive functions. Little is known, however, about the effects of marijuana use on other cognitive domains, such as decision-making, which are thought to play an important role in addiction and drug abuse. The purpose of the present study was to determine if long-term heavy marijuana users employ different decision-making strategies than individuals with minimal marijuana exposure. Volunteers were assigned to a cannabis (n = 10) or control group (n = 10) based upon history of prior marijuana use. Demographic and neuropsychological variables were evaluated, and a decision-making task--the gambling task (GT) was administered. Although few demographic and neuropsychological differences were noted between groups, marijuana users made more decisions that led to larger immediate gains despite more costly losses than controls. These data suggest that long-term heavy marijuana users may have specific deficits in the ability to balance rewards and punishments that may contribute to continued drug-taking behavior. It is unknown, however, whether the basis for such deficits might be attributed directly to marijuana exposure or pre-existing genetic or behavioral differences.

    2016-06-01

    Decision-making is the process of selecting a course of action from among 2 or more alternatives by considering the potential outcomes of selecting each option and estimating its consequences in the short, medium and long term. The prefrontal cortex (PFC) has traditionally been considered the key neural structure in decision-making process. However, new studies support the hypothesis that describes a complex neural network including both cortical and subcortical structures. The aim of this review is to summarise evidence on the anatomical structures underlying the decision-making process, considering new findings that support the existence of a complex neural network that gives rise to this complex neuropsychological process. Current evidence shows that the cortical structures involved in decision-making include the orbitofrontal cortex (OFC), anterior cingulate cortex (ACC), and dorsolateral prefrontal cortex (DLPFC). This process is assisted by subcortical structures including the amygdala, thalamus, and cerebellum. Findings to date show that both cortical and subcortical brain regions contribute to the decision-making process. The neural basis of decision-making is a complex neural network of cortico-cortical and cortico-subcortical connections which includes subareas of the PFC, limbic structures, and the cerebellum.

    The purpose of this study was to describe factors contributing to the decision-making processes of elderly persons as they formulate advance directives in long-term care. This study was qualitative, based on grounded theory. Recruitment was purposive and continued until saturation was reached. Nine residents of a long-term-care facility were interviewed by use of a semistructured format. Open and axial coding of interview transcripts were carried out and the factors contributing to the decision process were defined. Elders based their decisions primarily on information gathered from personal experiences with death and illness. They obtained very little information from professionals or the media. Major factors considered by elders as they weighed information included spiritual, emotional, and social considerations. The factors considered during the decision-making process were oriented more toward the individual's experiences and less on contributions from objective sources than anticipated. Decision making for advance directives is a highly personalized process. The approach of health professionals when assisting with end-of-life decision making should be planned with these contributing factors in mind, so that the services offered to the individuals in this population best meet their needs.

      Behaviours regarding food and activity are learned during childhood and continue throughout life. Children can be very important agents in making decisions concerning their own well-being and care and their perspective is essential to understanding how they and/or others make choices for them to achieve a healthy lifestyle. However, their perspectives remain under-researched. This study provides an insight into school children's own perspectives, behaviours and contribution to food and activity choices.   The paper reports on the findings from an ethnographic study with 38 Spanish children aged 5-7 years. Information was obtained through participant observations, diaries kept by children and group interviews. Data were analysed using techniques of analytical induction and constant comparison.   The children who took part in this study described choices about activities with enthusiasm. Children saw activity as a way of learning new things, mastering skills and socializing. They were willing to try and experience new activities and games. However, the activities performed depended on parents' agendas and security issues. In contrast, children reported less interest in and active involvement in food choices. They contributed to family food choices indirectly through the expression of their preferences, not wanting to eat what they disliked or tasting new foods.   Children had strong preferences and motivations, particularly about activities which could be harnessed in interventions to prevent obesity and promote healthy diet and activity. Parental involvement and commitment is also important both to encourage exercise according to children's interests and active informed food choices, including introduction to unfamiliar foods. © 2012 Blackwell Publishing Ltd.

    Full Text Available Impaired decision-making is a core problem in several psychiatric disorders including attention-deficit/hyperactivity disorder, schizophrenia, obsessive compulsive disorder, mania, drug addiction, eating disorders, and substance abuse as well as in chronic pain. To ensure progress in the understanding of the neuropathophysiology of these disorders, animals models with good construct and predictive validity are indispensable. Many human studies aimed at measuring decision-making capacities use the Iowa Gambling Task, a task designed to model every-day life choices through a conflict between immediate gratification and long-term outcomes. Recently, new rodent models based on the same principle have been developed to investigate the neurobiological mechanisms underlying IGT-like decision-making on behavioral, neural and pharmacological levels. The comparative strengths, as well as the similarities and differences between these paradigms are discussed. The contribution of these models to elucidate the neurobehavioral factors that lead to poor decision-making and to the development of better treatments for psychiatric illness is considered, along with important future directions and potential limitations.

  12. The importance of making right knowledge about radiation popular. Activity of 'radiation education forum'

    Radiation and radionuclides are not only indispensable in medical diagnoses and treatments, but are widely used in fundamental researches in various fields and in industry, thus contribute much to humans for elevating the quality of life. Nuclear power production is also playing an important role in saving the nonrenewable natural energy resources, without producing potentially problematic carbon dioxide. However, a majority of people has an excessive concern for radiation and radioactivity even for very minute quantities. This is due to the following three facts: (1) the first use of nuclear energy as the disastrous weapon in 1945 has resulted a profound after-effect in socio-psychological sense especially in Japan, (2) the major accidents of nuclear power plants which occurred in 1980's have been repeatedly reported in mass media with undue sensationalism, and (3) the proposition, that every ray of ionizing radiation may destroy DNA of human cells and is harmful by bringing carcinogenic or hereditary effects, has fixed as a suspicion-free common sense for general public. This proposition has its basis on the recommendation by ICRP of adopting the LNT (linear non-threshold), model even for low dose of radiations comparative with the natural radiation level. Thus the majority of people shows the syndrome of radio phobia'. Because there are so many risks other than radiation in the present day civilization, the extremely severe regulation only of radiation has many social demerits, and it is highly necessary that this situation be improved, by making the correct scientific information popular to the public. As an approach to this goal, a voluntary group, 'Radiation Education Forum', comprised of scientists, schoolteachers, journalists and citizens, has been established in 1994 in Japan, and has continued various types of activities. Because the social education has its basis on the school education, we have focussed our energy mainly for

    In order to further contribute to sustainable global bioenergy development, UNIDO will this year be launching the Bioenergy Capacity Building Programme (BIOCAB), offering a comprehensive training package to policy makers and entrepreneurs aimed at enhancing their engagement in shaping a sustainable bioenergy industry in developing countries. The training package, disseminated through a network of key institutions and certified trainers, will consist of four modules covering the following subjects: Technologies and Processes, Policy, Socio-Economic and Environmental Issues, Financial and Project Development Issues, Industrial Applications for Productive Use. While designing the training package and its modules at a meeting hosted by UNIDO at headquarters in August 2008, experts reiterated a demand, previously expressed by UNIDO clients at various international fora, for an easy-to-read, practical and user-friendly introduction to certain contentious bioenergy issues. The expert meeting selected the most hotly-debated bioenergy issues and came up with the following eight topics: (1) Jatropha, the feedstock of the future?; (2) Biomethane, is it an underestimated energy source?; (3) Energy from Municipal Solid Waste, can this potential be realized?; (4) The Biorefinery Concept, how relevant is it for developing countries?; (5) Competition with Food, what are the facts in the food versus fuel discussion?; (6) Sustainability and Certification of Biomass, what are the benefits?; (7) Clean Development Mechanism, how does it work?; (8) Success Stories.

  17. Inflammation, gene mutation and photoimmunosuppression in response to UVR-induced oxidative damage contributes to photocarcinogenesis

    Ultraviolet (UV) radiation causes inflammation, gene mutation and immunosuppression in the skin. These biological changes are responsible for photocarcinogenesis. UV radiation in sunlight is divided into two wavebands, UVB and UVA, both of which contribute to these biological changes, and therefore probably to skin cancer in humans and animal models. Oxidative damage caused by UV contributes to inflammation, gene mutation and immunosuppression. This article reviews evidence for the hypothesis that UV oxidative damage to these processes contributes to photocarcinogenesis. UVA makes a larger impact on oxidative stress in the skin than UVB by inducing reactive oxygen and nitrogen species which damage DNA, protein and lipids and which also lead to NAD+ depletion, and therefore energy loss from the cell. Lipid peroxidation induces prostaglandin production that in association with UV-induced nitric oxide production causes inflammation. Inflammation drives benign human solar keratosis (SK) to undergo malignant conversion into squamous cell carcinoma (SCC) probably because the inflammatory cells produce reactive oxygen species, thus increasing oxidative damage to DNA and the immune system. Reactive oxygen or nitrogen appears to cause the increase in mutational burden as SK progress into SCC in humans. UVA is particularly important in causing immunosuppression in both humans and mice, and UV lipid peroxidation induced prostaglandin production and UV activation of nitric oxide synthase is important mediators of this event. Other immunosuppressive events are likely to be initiated by UV oxidative stress. Antioxidants have also been shown to reduce photocarcinogenesis. While most of this evidence comes from studies in mice, there is supporting evidence in humans that UV-induced oxidative damage contributes to inflammation, gene mutation and immunosuppression. Available evidence implicates oxidative damage as an important contributor to sunlight-induced carcinogenesis in humans.

    Various international laws and guidelines stress the importance of respecting the developing autonomy of children and involving minors in decision-making regarding treatment and research participation. However, no universal agreement exists as to at what age minors should be deemed decision-making competent. Minors of the same age may show different levels of maturity. In addition, patients deemed rational conversation-partners as a child can suddenly become noncompliant as an adolescent. Age, context and development all play a role in decision-making competence. In this article we adopt a perspective on competence that specifically focuses on the impact of brain development on the child's decision-making process. We believe that the discussion on decision-making competence of minors can greatly benefit from a multidisciplinary approach. We adopted such an approach in order to contribute to the understanding on how to deal with children in decision-making situations. Evidence emerging from neuroscience research concerning the developing brain structures in minors is combined with insights from various other fields, such as psychology, decision-making science and ethics. Four capacities have been described that are required for (medical) decision-making: (1) communicating a choice; (2) understanding; (3) reasoning; and (4) appreciation. Each capacity is related to a number of specific skills and abilities that need to be sufficiently developed to support the capacity. Based on this approach it can be concluded that at the age of 12 children can have the capacity to be decision-making competent. However, this age coincides with the onset of adolescence. Early development of the brain's reward system combined with late development of the control system diminishes decision-making competence in adolescents in specific contexts. We conclude that even adolescents possessing capacities required for decision-making, may need support of facilitating environmental factors

    Risk comparison is essential for effective societal and individual decision-making. After the Fukushima disaster, studies compared radiation and other disaster-related risks to determine the effective prioritizing of measures for response. Evaluating the value of risk comparison information can enable effective risk communication. In this review, the value of risk comparison after the Fukushima disaster for societal and individual decision-making is discussed while clarifying the concept of radiation risk assessment at low doses. The objectives of radiation risk assessment are explained within a regulatory science framework, including the historical adoption of the linear non-threshold theory. An example of risk comparison (i.e. radiation risk versus evacuation-related risk in nursing homes) is used to discuss the prioritization of pre-disaster measures. The effective communication of risk information by authorities is discussed with respect to group-based and face-to-face approaches. Furthermore, future perspectives regarding radiation risk comparisons are discussed. © The Author(s) 2018.

    Full Text Available Spasticity is considered an important neural contributor to muscle hypertonia in children with cerebral palsy (CP. It is most often treated with antispasticity medication, such as Botulinum Toxin-A. However, treatment response is highly variable. Part of this variability may be due to the inability of clinical tests to differentiate between the neural (e.g., spasticity and nonneural (e.g., soft tissue properties contributions to hypertonia, leading to the terms “spasticity” and “hypertonia” often being used interchangeably. Recent advancements in instrumented spasticity assessments offer objective measurement methods for distinction and quantification of hypertonia components. These methods can be applied in clinical settings and their results used to fine-tune and improve treatment. We reviewed current advancements and new insights with respect to quantifying spasticity and its contribution to muscle hypertonia in children with CP. First, we revisit what is known about spasticity in children with CP, including the various definitions and its pathophysiology. Second, we summarize the state of the art on instrumented spasticity assessment in CP and review the parameters developed to quantify the neural and nonneural components of hypertonia. Lastly, the impact these quantitative parameters have on clinical decision-making is considered and recommendations for future clinical and research investigations are discussed.

    Heuristics involve the ability to utilize memory to make quick judgments by exploiting fundamental cognitive abilities. In the current study we investigated the memory processes that contribute to the recognition heuristic and the fluency heuristic, which are both presumed to capitalize on the byproducts of memory to make quick decisions. In Experiment 1, we used a city-size comparison task while recording event-related potentials (ERPs) to investigate the potential contributions of familiarity and recollection to the 2 heuristics. ERPs were markedly different for recognition heuristic-based decisions and fluency heuristic-based decisions, suggesting a role for familiarity in the recognition heuristic and recollection in the fluency heuristic. In Experiment 2, we coupled the same city-size comparison task with measures of subjective preexperimental memory for each stimulus in the task. Although previous literature suggests the fluency heuristic relies on recognition speed alone, our results suggest differential contributions of recognition speed and recollected knowledge to these decisions, whereas the recognition heuristic relies on familiarity. Based on these results, we created a new theoretical framework that explains decisions attributed to both heuristics based on the underlying memory associated with the choice options.

    2015-12-01

    Full Text Available Immigrants have played a fundamental role in shaping the life and form of urban public spaces for generations. Their efforts, as many scholars have observed, mostly aimed at creating places of comfort in new and sometimes hostile receiving countries. In recent years, the combined contribution of the built environment and screen-based experiences have shaped migrants’ sense of community and belonging, thus making the concept of online community central to ideas about space and public life. Drawing upon a 3-year online ethnography, the article discusses to what extent new media constitute spaces of digital togetherness , where diasporic experiences and transnational identities are constructed and negotiated. It presents a transnational model of creative media consumption, which helps give insight as to how diasporas and ethnic minorities contribute to the transformation of public space in the Digital Age.

    To characterise the diets of pregnant women in the Republic of Seychelles and to determine the contribution of fish to intakes of nutrients important for fetal and neonatal development. Observational, prospective study. Seychelles Child Development Centre, Mahé, Republic of Seychelles. Pregnant women (n 300) were recruited at their first visit to an antenatal clinic. At 28 weeks' gestation subjects completed a 4 d diet diary (n 273) and intakes were analysed using dietary analysis software. Mean (sd) energy intake was 9.0 (2.5) MJ/d and fat intakes were higher than UK recommendations for almost two-thirds of the cohort. Fish consumption was lower than in previous surveys, suggesting a move towards a more Westernised diet. Low intakes of a number of nutrients important during pregnancy for fetal development (Fe, Zn, Se and iodine) were observed. However, women who met the current recommendations for these nutrients consumed significantly more fish than those who did not (97 v. 73 g/d). The present study highlights the importance of fish in the diet of pregnant Seychellois women for ensuring adequate intakes of micronutrients important in fetal development. Dietary patterns in Seychelles, however, are in a state of transition, with a move towards a Western-style diet as evidenced by higher fat and lower fish intakes. If these dietary trends continue and fish consumption declines further, micronutrient status may be compromised. These findings suggest caution in establishing public health policies that promote limitation of fish intake during pregnancy.

    This letter reports a first quantitative analysis of the contribution of higher partial waves in the charge symmetry breaking reaction dd →4Heπ0 using the WASA-at-COSY detector setup at an excess energy of Q = 60MeV. The determined differential cross section can be parametrized as d σ /d Ω = a + bcos2 ⁡θ*, where θ* is the production angle of the pion in the center-of-mass coordinate system, and the results for the parameters are a = (1.55 ± 0.46(stat) + 0.32 - 0.8 (syst)) pb /sr and b = (13.1 ± 2.1 (stat)-2.7+1.0 (syst)) pb /sr. The data are compatible with vanishing p-waves and a sizable d-wave contribution. This finding should strongly constrain the contribution of the Δ isobar to the dd →4Heπ0 reaction and is, therefore, crucial for a quantitative understanding of quark mass effects in nuclear production reactions.

    Veatch considers the pluralistic casuistry theory advocated by Baruch Brody in his 1988 book, Life and Death Decision Making, to be an important contribution to the secular medical ethics literature. The casuistic and pluralistic elements of Brody's new model are described as intriguing but controversial because Brody both excludes several ethical appeals (i.e., classical Hippocratic ethics, virtue theory) and/or limits other questionable appeals (i.e., consequences for families and others in society, the virtue of integrity) without accounting for these decisions. Veatch also questions Brody's use of intuitional judgment to determine what ought to be done after examination of various appeals and their significance because Brody's approach raises serious problems about how various appeals are counted. Veatch does affirm the rich assessment of medical ethical problems made possible by Brody's pluralistic approach but notes the difficulties it raises.

    2010-09-15

    Social acceptability is increasingly described in the discourse of social players as a sine qua non condition for projects to be carried out. It is referred to as an approach (participation in the decision-making process) and as an outcome (citizens' concurrence with the decision). The application of this new concept generated considerable expectations. In our opinion, social acceptability must pass through three complementary stages: i) discussing material (downstream) and structural (upstream) issues; ii) establishing a transparent and equitable consultation process; and iii) ensuring that a legitimate decision-making process occurs.

    2009-03-06

    The obesity epidemic has generated interest in determining the contribution of various pathways to triglyceride synthesis, including an elucidation of the origin of triglyceride fatty acids and triglyceride glycerol. We hypothesized that a dietary intervention would demonstrate the importance of using glucose versus non-glucose carbon sources to synthesize triglycerides in white adipose tissue. C57BL/6J mice were fed either a low fat, high carbohydrate (HC) diet or a high fat, carbohydrate-free (CF) diet and maintained on 2H2O (to determine total triglyceride dynamics) or infused with [6,6-(2)H]glucose (to quantify the contribution of glucose to triglyceride glycerol). The 2H2O labeling data demonstrate that although de novo lipogenesis contributed approximately 80% versus approximately 5% to the pool of triglyceride palmitate in HC- versus CF-fed mice, the epididymal adipose tissue synthesized approximately 1.5-fold more triglyceride in CF- versus HC-fed mice, i.e. 37+/-5 versus 25+/-3 micromolxday(-1). The [6,6-(2)H]glucose labeling data demonstrate that approximately 69 and approximately 28% of triglyceride glycerol is synthesized from glucose in HC- versus CF-fed mice, respectively. Although these data are consistent with the notion that non-glucose carbon sources (e.g. glyceroneogenesis) can make substantial contributions to the synthesis of triglyceride glycerol (i.e. the absolute synthesis of triglyceride glycerol from non-glucose substrates increased from approximately 8 to approximately 26 micromolxday(-1) in HC- versus CF-fed mice), these observations suggest (i) the importance of nutritional status in affecting flux rates and (ii) the operation of a glycerol-glucose cycle.

    Full Text Available We live in challenging times with a heightened sense of uncertainty and unpredictability. Climate change, with its impact on disruptive events as well as gradual trends, has been addressed in scientific studies and become increasingly important in policymaking. This rises up a great need on scientific integration and knowledge transformation. The Taiwan Integrated Research Programme on Climate Change Adaptation Technology (TaiCCAT is formed under this concern. Directing by the Ministry of Science and Technology (MOST, it carries a strong intention to explore and to conduct adequate knowledge of climate change and adaptation strategies for decision-making supports. The TaiCCAT highly recommends the approach of cross-disciplinary collaboration from environmental studies to adaptation governance. The result can therefore be more contributive to reflect the complexity of the changing world.

    When making decisions in everyday life, we often have to choose between uncertain outcomes. Economic studies have demonstrated that healthy people tend to prefer options with known probabilities (risk) than those with unknown probabilities (ambiguity), which is referred to as "ambiguity aversion." However, it remains unclear how patients with schizophrenia behave under ambiguity, despite growing evidence of their altered decision-making under uncertainty. In this study, combining economic tools and functional magnetic resonance imaging (fMRI), we assessed the attitudes toward risk/ambiguity and investigated the neural correlates during decision-making under risk/ambiguity in schizophrenia. Although no significant difference in attitudes under risk was observed, patients with schizophrenia chose ambiguity significantly more often than the healthy controls. Attitudes under risk and ambiguity did not correlate across patients with schizophrenia. Furthermore, unlike in the healthy controls, activation of the left lateral orbitofrontal cortex was not increased during decision-making under ambiguity compared to under risk in schizophrenia. These results suggest that ambiguity aversion, a well-established subjective bias, is attenuated in patients with schizophrenia, highlighting the need to distinguish between risk and ambiguity when assessing decision-making under these situations. Our findings, comprising important clinical implications, contribute to improved understanding of the mechanisms underlying altered decision-making in patients with schizophrenia.

  1. Prefrontal Cortical Inactivations Decrease Willingness to Expend Cognitive Effort on a Rodent Cost/Benefit Decision-Making Task.

    2016-04-01

    Personal success often necessitates expending greater effort for greater reward but, equally important, also requires judicious use of our limited cognitive resources (e.g., attention). Previous animal models have shown that the prelimbic (PL) and infralimbic (IL) regions of the prefrontal cortex (PFC) are not involved in (physical) effort-based choice, whereas human studies have demonstrated PFC contributions to (mental) effort. Here, we utilize the rat Cognitive Effort Task (rCET) to probe PFC's role in effort-based decision making. In the rCET, animals can choose either an easy trial, where the attentional demand is low but the reward (sugar) is small or a difficult trial on which both the attentional demand and reward are greater. Temporary inactivation of PL and IL decreased all animals' willingness to expend mental effort and increased animals' distractibility; PL inactivations more substantially affected performance (i.e., attention), whereas IL inactivations increased motor impulsivity. These data imply that the PFC contributes to attentional resources, and when these resources are diminished, animals shift their choice (via other brain regions) accordingly. Thus, one novel therapeutic approach to deficits in effort expenditure may be to focus on the resources that such decision making requires, rather than the decision-making process per se. © The Author 2015.

    2017-06-01

    Partnerships between service users and social workers are complex in nature and can be driven by both personal and contextual circumstances. This study sought to explore the relationship between social workers' involvement in shared decision making with service users, their attitudes towards service users in poverty, moral standards and health and social care organizations' policies towards shared decision making. Based on the responses of 225 licensed social workers from health and social care agencies in the public, private and third sectors in Israel, path analysis was used to test a hypothesized model. Structural attributions for poverty contributed to attitudes towards people who live in poverty, which led to shared decision making. Also, organizational support in shared decision making, and professional moral identity, contributed to ethical behaviour which led to shared decision making. The results of this analysis revealed that shared decision making may be a scion of branched roots planted in the relationship between ethics, organizations and Stigma. © 2016 The Authors.

    Burnout is highly prevalent in medical residents. In order to prevent or reduce burnout in medical residents, we should gain a better understanding of contributing and protective factors of burnout. Therefore we examined the associations of job demands and resources, home demands and resources, and work-home interferences with burnout in male and female medical residents. This study was conducted on a nation-wide sample of medical residents. In 2005, all Dutch medical residents (n = 5245) received a self-report questionnaire on burnout, job and home demands and resources and work-home interference. Path analysis was used to examine the associations between job and home characteristics and work-home interference and burnout in both males and females. In total, 2115 (41.1 %) residents completed the questionnaire. In both sexes emotional demands at work and the interference between work and home were important contributors to burnout, especially when work interferes with home life. Opportunities for job development appeared to be an important protective factor. Other contributing and protective factors were different for male and female residents. In females, social support from family or partner seemed protective against burnout. In males, social support from colleagues and participation in decision-making at work seemed important. Effectively handling emotional demands at work, dealing with the interference between work and home, and having opportunities for job development are the most essential factors which should be addressed. However it is important to take gender differences into consideration when implementing preventive or therapeutic interventions for burnout in medical residents.

  9. The decision-making process in public healthcare entities – identification of the decision-making process type

    2017-05-01

    Full Text Available The decisions made in the organization determine its success, therefore, conducting studies in the scope of decision-making seems important both for theory and practice. The aim of the studies was to identify the type of decision-making process in public medical entities with the use of typology developed by P. Nutt. For this purpose we used qualitative methods. Interviews with 8 directors of hospitals were conducted and the reconstruction was made on the basis of the decision-making process, which enabled the assignment of the model of decision-making process to the organization. The research indicated that four organizations use the historical decision-making model, three organizations represent the model of generating solutions, and one organization uses the model of available solutions.

    Increasing interest in empirical ethics has enhanced understanding of healthcare professionals' ethical problems and attendant decision-making. A four-stage decision-making model involving ethical attention, reasoning, intention and action offers further insights into how more than reasoning alone may contribute to decision-making. To explore how the four-stage model can increase understanding of decision-making in healthcare and describe the decision-making of an under-researched professional group. 23 purposively sampled UK community pharmacists were asked, in semi-structured interviews, to describe ethical problems in their work and how they were resolved. Framework analysis of transcribed interviews utilised the four decision-making stages, together with constant comparative methods and deviant-case analysis. Pharmacists were often inattentive and constructed problems in legal terms. Ethical reasoning was limited, but examples of appeals to consequences, the golden rule, religious faith and common-sense experience emerged. Ethical intention was compromised by frequent concern about legal prosecution. Ethical inaction was common, typified by pharmacists' failure to report healthcare professionals' bad practices, and ethical passivity emerged to describe these negative examples of the four decision-making stages. Pharmacists occasionally described more ethically active decision-making, but this often involved ethical uncertainty. The four decision-making stages are a useful tool in considering how healthcare professionals try to resolve ethical problems in practice. They reveal processes often ignored in normative theories, and their recognition and the emergence of ethical passivity indicates the complexity of decision-making in practice. Ethical passivity may be deleterious to patients' welfare, and concerns emerge about improving pharmacists' ethical training and promoting ethical awareness and responsibility.

    Stiegler, Marjorie Podraza; Tung, Avery

    2014-01-01

    The quality and safety of health care are under increasing scrutiny. Recent studies suggest that medical errors, practice variability, and guideline noncompliance are common, and that cognitive error contributes significantly to delayed or incorrect diagnoses. These observations have increased interest in understanding decision-making psychology.Many nonrational (i.e., not purely based in statistics) cognitive factors influence medical decisions and may lead to error. The most well-studied include heuristics, preferences for certainty, overconfidence, affective (emotional) influences, memory distortions, bias, and social forces such as fairness or blame.Although the extent to which such cognitive processes play a role in anesthesia practice is unknown, anesthesia care frequently requires rapid, complex decisions that are most susceptible to decision errors. This review will examine current theories of human decision behavior, identify effects of nonrational cognitive processes on decision making, describe characteristic anesthesia decisions in this context, and suggest strategies to improve decision making.

    The problem I would like to highlight in this contribution is that gamification has been thought about too much as a tool for problem solving, and not enough as a tool for problem making. The idea of gamification as a tool for problem making could be more useful – although maybe paradoxically. As long as a technique is presented as a method for the solution of problems it can too easily become an authoritative proposal, which takes one solution and vision as necessarily better than the others...

    Full Text Available We present a motivational account of the impact of emotion on decision making, termed the feeling-is-for-doing approach. We first describe the psychology of emotion and argue for a need to be specific when studying emotion's impact on decision making. Next we describe what our approach entails and how it relates emotion, via motivation to behavior. Then we offer two illustrations of our own research that provide support for two important elements in our reasoning. We end with specifying four criteria that we consider to be important when studying how feeling guides our everyday doing.

    2006-07-01

    To investigate the degree of job burnout and contributing factors for nurses. A total of 495 nurses from three provincial hospitals were randomly selected. The MBI-GS, EPQ-RSC and OSI-R were administered to measure job burnout, personality traits and occupational stress, respectively. The medical and surgical nurses had significant greater scores of job burnout than others (P < 0.05). The poorer educational background was correlated with lower professional efficacy. The younger nurses had stronger feeling of job burnout. The scores of job burnout changed with different personality traits. The main contributing variables to exhaustion were overload, sense of responsibility, role insufficient and self-care (P < 0.05). The main contributing variables to cynicism were role insufficiency, role boundary, sense of responsibility and self-care (P < 0.05). The main contributing variables to professional inefficacy were role insufficiency, social support and rational/cognitive coping (P < 0.05). Job burnout for nurses can be prevented by reducing or keeping moderate professional duties and responsibility, making clearer job descriptions, promoting leisure activities, and enhancing self-care capabilities.

  17. Strategic Control in Decision Making under Uncertainty

    Venkatraman, Vinod; Huettel, Scott

    2012-01-01

    Complex economic decisions – whether investing money for retirement or purchasing some new electronic gadget – often involve uncertainty about the likely consequences of our choices. Critical for resolving that uncertainty are strategic meta-decision processes, which allow people to simplify complex decision problems, to evaluate outcomes against a variety of contexts, and to flexibly match behavior to changes in the environment. In recent years, substantial research implicates the dorsomedial prefrontal cortex (dmPFC) in the flexible control of behavior. However, nearly all such evidence comes from paradigms involving executive function or response selection, not complex decision making. Here, we review evidence that demonstrates that the dmPFC contributes to strategic control in complex decision making. This region contains a functional topography such that the posterior dmPFC supports response-related control while the anterior dmPFC supports strategic control. Activation in the anterior dmPFC signals changes in how a decision problem is represented, which in turn can shape computational processes elsewhere in the brain. Based on these findings, we argue both for generalized contributions of the dmPFC to cognitive control, and for specific computational roles for its subregions depending upon the task demands and context. We also contend that these strategic considerations are also likely to be critical for decision making in other domains, including interpersonal interactions in social settings. PMID:22487037

    Full Text Available Peoples’ decision-making competence, defined as tendency to follow normative rational principles in their decision making, is important as it may influence the extent that requirements are met and levels of perceived stress. In addition, perceived stress could be influenced by social orientation and time style; for example, decisions need to comply with given deadlines and the expectations of others. In two studies, with students (n = 118 and professionals (police investigators, n = 90, we examined how the three individual difference features: decision-making competence, social orientation, and time approach relate to perceived stress. Results showed that social orientation and time approach were related to levels of perceived stress, but decision-making competence was not. These results indicate that social orientation and time approach are important to consider in relation to perceived stress, but the role of decision-making competence may be less important for perceived stress. However, the role of decision-making competence for perceived stress needs to be further researched.

    As society is confronted with population growth, limited resources, and the impacts of climate variability and change, it is vital that institutions of higher education promote the development of professionals who can work with decision-makers to incorporate scientific information into environmental planning and management. Skills for the communication of science are essential, but equally important is the ability to understand decision-making contexts and engage with resource managers and policy makers. It is increasingly being recognized that people who understand the linkages between science and decision making are crucial if science is to better support planning and policy. A new graduate-level seminar, "Making the Connection between Environmental Science and Decision Making," is a core course for a new post-baccalaureate certificate program, Connecting Environmental Science and Decision Making at the University of Arizona. The goal of the course is to provide students with a basic understanding of the dynamics between scientists and decision makers that result in scientific information being incorporated into environmental planning, policy, and management decisions. Through readings from the environmental and social sciences, policy, and planning literature, the course explores concepts including scientific information supply and demand, boundary organizations, co-production of knowledge, platforms for engagement, and knowledge networks. Visiting speakers help students understand some of the challenges of incorporating scientific information into planning and decision making within institutional and political contexts. The course also includes practical aspects of two-way communication via written, oral, and graphical presentations as well as through the interview process to facilitate the transfer of scientific information to decision makers as well as to broader audiences. We aspire to help students develop techniques that improve communication and

    1995-12-31

    A critical aspect of climate change decision-making is uncertainties in current understanding of the socioeconomic, climatic and biogeochemical processes involved. Decision-making processes are much better informed if these uncertainties are characterized and their implications understood. Quantitative analysis of these uncertainties serve to inform decision makers about the likely outcome of policy initiatives, and help set priorities for research so that outcome ambiguities faced by the decision-makers are reduced. A family of integrated assessment models of climate change have been developed at Carnegie Mellon. These models are distinguished from other integrated assessment efforts in that they were designed from the outset to characterize and propagate parameter, model, value, and decision-rule uncertainties. The most recent of these models is ICAM 2.1. This model includes representation of the processes of demographics, economic activity, emissions, atmospheric chemistry, climate and sea level change and impacts from these changes and policies for emissions mitigation, and adaptation to change. The model has over 800 objects of which about one half are used to represent uncertainty. In this paper we show, that when considering parameter uncertainties, the relative contribution of climatic uncertainties are most important, followed by uncertainties in damage calculations, economic uncertainties and direct aerosol forcing uncertainties. When considering model structure uncertainties we find that the choice of policy is often dominated by model structure choice, rather than parameter uncertainties.

  4. Supporting and structuring "contributing student pedagogy" in Computer Science curricula

    Falkner, Katrina; Falkner, Nickolas J. G.

    2012-12-01

    Contributing student pedagogy (CSP) builds upon social constructivist and community-based learning principles to create engaging and productive learning experiences. What makes CSP different from other, related, learning approaches is that it involves students both learning from and also explicitly valuing the contributions of other students. The creation of such a learning community builds upon established educational psychology that encourages deep learning, reflection and engagement. Our school has recently completed a review and update of its curriculum, incorporating student content-creation and collaboration into the design of key courses across the curriculum. Our experiences, based on several years of experimentation and development, support CSP-based curriculum design to reinforce the value of the student perspective, the clear description of their own transformative pathway to knowledge and the importance of establishing student-to-student networks in which students are active and willing participants. In this paper, we discuss the tools and approaches that we have employed to guide, support and structure student collaboration across a range of courses and year levels. By providing an account of our intentions, our approaches and tools, we hope to provide useful and transferrable knowledge that can be readily used by other academics who are considering this approach.

It was determined that 37.6% women prepare feed, 40% women feed the animals, 51% women clean stables, 85.2% women make cowpat and 89.5% of them milk. As a result, it is determined that employing and promoting women who play a crucial role in agriculture and livestock activities in working status, giving instructional seminars about animal production and supporting their socio-economic status are important in terms of having qualified livestock production.

  8. Individual decision making, group decision making and deliberation

    Full Text Available Each of us makes a number of decisions, from the less important to those with far-reaching consequences. As members of different groups, we are also actors of group decision making. In order to make a rational decision, a choice-making procedure must satisfy a number of assumptions (conditions of rationality. In addition, when it comes to group decisions, those procedures should also be “fair.” However, it is not possible to define a procedure of choice-making that would transform individual orders of alternatives based on preferences of perfectly rational individuals into a single social order and still meet conditions of rationality and ethics. The theory of deliberative democracy appeared in response to the impossibility of Social Choice theory. The basic assumption of deliberative democracy is that individuals adjust their preferences taking into account interests of the community. They are open for discussion with other group members and are willing to change their attitudes in order to achieve common interests. Ideally, group members come to an agreement during public discussion (deliberation. Still, this concept cannot completely over­come all the difficulties posed by the theory of social choice. Specifically, there is no solution for strategic and manipulative behavior of individuals. Also, the concept of deliberative democracy faces certain problems particular to this approach, such as, to name but a few, problems with the establishment of equality of participants in the debate and their motivation, as well as problems with the organization of public hearings.

    A black-hole is unstable to zero-means quantum fluctuations of its metric. These quantum fluctuations break the degeneracy of the locations of the event-horizon and the apparent-horizon for a Schwarzschild black-hole. The path-integral in spacetime with Euclidean signature is calculated from the ADM action to second order in the variations. It is found that the second-order term of this perturbation expansion gives the same contribution to the path-integral as the zeroth-order term for these particular fluctuations. A surface near the black-hole event-horizon is correctly treated as a boundary, and this surface makes a substantial contribution to the path-integral. One may treat this path-integral as a partition function and calculate thermodynamic quantities. The entropy of this black-hole, for example, is found to be close to the accepted value of A/4h, where A is the black-hole surface area. The meaning of these particular fluctuations and the importance of the boundary near the event-horizon is discussed

    Prospective memory (ProM), a form of episodic memory related to execution of future intentions, is important for everyday functioning. Among persons living with HIV (PLWH), executive dysfunction is implicated in ProM impairments. However, specific subcomponents of executive functioning involved in ProM deficits remain poorly understood. Unlike more "traditional" neurocognitive (NC) measures of executive functioning associated with dorsolateral prefrontal cortex (i.e., conceptual reasoning, abstraction), those associated with medial orbitofrontal/ventromedial prefrontal (mOF/vmP) cortex (i.e., decision making, inhibitory control, goal-oriented behavior) have yet to be examined in ProM. This study characterized ProM ability in a sample of 89 HIV-seropositive adults and examined the unique role of decision-making ability in ProM. Participants completed a standard NC battery, the Iowa Gambling Task (IGT; a decision-making measure), and the Memory for Intentions Screening Test (MIST; a ProM measure). Correlational analyses revealed that both traditional executive functioning measures and the IGT were associated with ProM. Regression analyses revealed that the IGT significantly predicted ProM, even after accounting for NC measures. Among all NC measures, only executive functioning significantly contributed to ProM. Further examination of mOF/vmP-sensitive executive dysfunction within this population is needed as PLWH may require more tailored treatment recommendations due to specific decision-making difficulties that can impact medication management.

    2016-07-01

    Sociality is suggested to evolve as a strategy for animals to cope with challenges in their environment. Within a population, each individual can be seen as part of a network of social interactions that vary in strength, type and dynamics (Sueur et al. 2011a). The structure of this social network can strongly impact upon not only on the fitness of individuals and their decision-making, but also on the ecology of populations and the evolution of a species. Our Franco-Japanese collaboration allowed us to study social networks in several species (Japanese macaques, chimpanzees, colobines, etc.) and on different topics (social epidemiology, social evolution, information transmission). Individual attributes such as stress, rank or age can affect how individuals take decisions and the structure of the social network. This heterogeneity is linked to the assortativity of individuals and to the efficiency of the flow within a network. It is important, therefore, that this heterogeneity is integrated in the process or pattern under study in order to provide a better resolution of investigation and, ultimately, a better understanding of behavioural strategies, social dynamics and social evolution. How social information affects decision-making could be important to understand how social groups make collective decisions and how information may spread throughout the social group. In human beings, road-crossing behaviours in the presence of other individuals is a good way to study the influence of social information on individual behaviour and decision-making, for instance. Culture directly affects which information - personal vs social - individuals prefer to follow. Our collaboration contributed to the understanding of the relative influence of different factors, cultural and ecological, on primate, including human, sociality.

    Inhaled therapies are central to the treatment of asthma and chronic obstructive pulmonary disease. Physicians consider many factors when selecting the most appropriate inhaler device, including device efficacy and the cost to the health care system. This review aims to discuss the factors that are important when considering inhaler devices and the importance of continuity in the choice of inhaler device. A large number of factors can contribute to therapeutic outcomes with inhalation devices. The inhalation technique is critical to treatment success and differs substantially between inhaler devices. Misuse of an inhaler is common, and thorough training of patients and physicians is important to ensure correct utilization. Patient satisfaction is an important consideration because it is significantly correlated with compliance and better outcomes. Financial pressures contribute to decision making: although selecting the less expensive inhaler device might reduce direct treatment costs, it can have a large impact on disease control and the patient's well-being. Switching may be associated with a poor inhalation technique, reduced disease control and quality of life, increased use of other treatments and health care resources, and a greater chance of unsuccessful treatment. Nonconsensual switches can result in patient discontent, reduced confidence in the medication, and uncertainty regarding the degree of disease control. It is recommended that patients with stable disease remain on their current device. If a switch is considered, the patient should be consulted and the physician should take into account the patient's preference, their ability to correctly use the device, and the availability of the preferred drug in the preferred device.

  15. The Die Is Cast: Precision Electrophilic Modifications Contribute to Cellular Decision Making.

    This perspective sets out to critically evaluate the scope of reactive electrophilic small molecules as unique chemical signal carriers in biological information transfer cascades. We consider these electrophilic cues as a new volatile cellular currency and compare them to canonical signaling circulation such as phosphate in terms of chemical properties, biological specificity, sufficiency, and necessity. The fact that nonenzymatic redox sensing properties are found in proteins undertaking varied cellular tasks suggests that electrophile signaling is a moonlighting phenomenon manifested within a privileged set of sensor proteins. The latest interrogations into these on-target electrophilic responses set forth a new horizon in the molecular mechanism of redox signal propagation wherein direct low-occupancy electrophilic modifications on a single sensor target are biologically sufficient to drive functional redox responses with precision timing. We detail how the various mechanisms through which redox signals function could contribute to their interesting phenotypic responses, including hormesis.

    2009-03-01

    In this rejoinder to Ann Kindfield and Grady Venville's comments on our article "Reconsidering conceptual change from a socio-cultural perspective: Analyzing students' meaning making in genetics in collaborative learning activities," we elaborate on some of the critical issues they raise. Their comments make apparent some of the crucial differences between a socio-cultural and a socio-cognitive approach towards conceptual change. We have selected some issues that are addressed, either implicitly or explicitly, in their comments. The main issues discussed are talk and interaction as data, the significance of context in interaction studies, the feasibility of generic claims in small-scale interaction studies, and the difference between studying students' understanding of science concepts as opposed to studying the construction of meaning.

  17. Importance and condition of forage crops seed production in agriculture of the Republic of Serbia

    Full Text Available For contemporary and economical livestock production, especially cattle and sheep raising, it is necessary to achieve high production of livestock feed while reducing production costs. Improving the production of perennial grasses and legumes creates a good basis for the development of livestock production in different agro-ecological conditions of Serbia. It also establishes a link between farming and animal husbandry, which is of particular importance for the preservation and higher fertility of arable land and the protection of agro-ecosystems. An important factor for the cheaper production of livestock feed is the possibility to provide sufficient quantities of quality seeds at affordable prices. Production of quality seeds of local varieties of perennial legumes is possible to obtain sufficient amounts of good quality forage. Current situation in forage crop seed production of the Republic of Serbia is unsatisfactory because the seed of perennial grasses are mostly imported. Domestic production of alfalfa, red clover and birdsfoot trefoil met domestic needs only in some years. Seed of imported varieties are often not satisfactory because those varieties are not adapted to our local agro-ecological conditions. The present results provide the basis and direction for further researches that may provide solutions to increase seed yields and which will be widely accepted in practice, which will make the production more cost-effective. Institute for forage crops Kruševac is making a significant contribution to the development of technology of seed productions, especially alfalfa, red clover and perennial grasses. Therefore the role of the Institute is very important and necessary link between production, processing and trading seeds of perennial legumes and grasses in Serbia.

    Pertl, Marie-Theres; Zamarian, Laura; Delazer, Margarete

    2017-08-01

    In this study, we assessed to what extent reasoning improves performance in decision making under risk in a laboratory gambling task (Game of Dice Task-Double, GDT-D). We also investigated to what degree individuals with above average mathematical competence decide better than those with average mathematical competence. Eighty-five participants performed the GDT-D and several numerical tasks. Forty-two individuals were asked to calculate the probabilities and the outcomes associated with the different options of the GDT-D before performing it. The other 43 individuals performed the GDT-D at the beginning of the test session. Both reasoning and mathematical competence had a positive effect on decision making. Different measures of mathematical competence correlated with advantageous performance in decision making. Results suggest that decision making under explicit risk conditions improves when individuals are encouraged to reflect about the contingencies of a decision situation. Interventions based on numerical reasoning may also be useful for patients with difficulties in decision making.

    2016-01-01

    In concert with 6 decennial White House Conferences on Aging, psychologists have considered how developments in psychological science can contribute to the well-being of older Americans. We suggest 5 illustrative areas of psychological research: Advances in neuroscience elucidate ways to promote healthy cognitive aging; associated developments in neuropsychological assessment can help in protecting older Americans with cognitive losses from financial exploitation, abuse, and neglect. Psychological research on decision making and behavioral economics has much to offer to planning for retirement security and reducing vulnerability to financial abuse. Psychological research on self-management and behavior change can contribute importantly to enhancing good health behaviors among older adults; similarly the power of context on behavior can be harnessed in long-term care settings. Psychological research on attitudes and stereotypes gives insight into age bias that can be detrimental to healthy aging. Adaptive technologies and information technologies are beginning to transform assessment in research and clinical settings; technology also holds the promise of improving long-term support for older adults in both institutional and community-based settings. Finally, with 1 in 7 Americans now ages 65 and older, compared with 1 in 11 50 years ago, the psychology workforce-including health services providers and faculty to train those providers-is insufficient to meet the challenge of the aging population.

  1. The MCM-associated protein MCM-BP is important for human nuclear morphology.

    2012-01-01

    Mini-chromosome maintenance complex-binding protein (MCM-BP) was discovered as a protein that is strongly associated with human MCM proteins, known to be crucial for DNA replication in providing DNA helicase activity. The Xenopus MCM-BP homologue appears to play a role in unloading MCM complexes from chromatin after DNA synthesis; however, the importance of MCM-BP and its functional contribution to human cells has been unclear. Here we show that depletion of MCM-BP by sustained expression of short hairpin RNA (shRNA) results in highly abnormal nuclear morphology and centrosome amplification. The abnormal nuclear morphology was not seen with depletion of other MCM proteins and was rescued with shRNA-resistant MCM-BP. MCM-BP depletion was also found to result in transient activation of the G2 checkpoint, slowed progression through G2 and increased replication protein A foci, indicative of replication stress. In addition, MCM-BP depletion led to increased cellular levels of MCM proteins throughout the cell cycle including soluble MCM pools. The results suggest that MCM-BP makes multiple contributions to human cells that are not limited to unloading of the MCM complex.

  2. Thermo-reversible inhibition makes aqualysin 1 from Thermus aquaticus a potent tool for studying the contribution of the wheat gluten network to the crumb texture of fresh bread.

    2018-10-30

    The thermo-active serine peptidase aqualysin 1 (Aq1) of Thermus aquaticus was applied in bread making to study the relative contribution of thermoset gluten to bread crumb texture. Aq1 is active between 30 °C and 90 °C with an optimum activity temperature of around 65 °C. It is inhibited by wheat endogenous serine peptidase inhibitors during dough mixing and fermentation and starts hydrolyzing gluten proteins during baking above 80 °C when the enzyme is no longer inhibited and most of the starch is gelatinized and contributes to structure formation. Aq1 activity reduced the molecular weight of gluten proteins and significantly increased their extractability in sodium dodecyl sulfate containing medium. While it had no impact on the specific bread volume and only limited impact on hardness, cohesiveness, springiness, resilience and chewiness, it impacted bread crumb coherence. We conclude that starch has a greater impact on crumb texture than thermoset gluten. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2017-11-01

    Full Text Available This article addresses the possibility of incorporating intelligent decision support systems into reinsurance decision-making. This involves the insurance company and the reinsurance company, and is negotiated through reinsurance intermediaries. The article proposes a decision flow to model the reinsurance design and selection process. This article focuses on adopting more than one optimality criteria under a more generic combinational design of commonly used reinsurance products, i.e., proportional reinsurance and stop-loss reinsurance. In terms of methodology, the significant contribution of the study the incorporation of the well-established decision analysis tool multiple-attribute decision-making (MADM into the modelling of reinsurance selection. To illustrate the feasibility of incorporating intelligent decision supporting systems in the reinsurance market, the study includes a numerical case study using the simulation software @Risk in modeling insurance claims, as well as programming in MATLAB to realize MADM. A list of managerial implications could be drawn from the case study results. Most importantly, when choosing the most appropriate type of reinsurance, insurance companies should base their decisions on multiple measurements instead of single-criteria decision-making models so that their decisions may be more robust.

    2012-01-01

    New legislation has been introduced in the Member States of the European Union, covering worker exposure to artificial optical radiation. Use of make-up could reduce the ultraviolet hazard level and provide additional protection for skin against UV radiation (UVR). This is particularly important in entertainment and filming where intentional exposure of the actors and presenters to the very intense light sources may be required for extended periods of time. This document presents the assessment of UVR protection of make-up used in entertainment and demonstrates that the protection level varies considerably for different luminaires and application techniques. An important practical implication of this finding is that make-up alone cannot be considered as a reliable protection measure against skin exposure to actinic UV. (authors)

  8. DECISION-MAKING STRATEGIES REGARDING LOGISTICS ORGANIZATION

    Directory of Open Access Journals (Sweden)

    Ioana Olariu

    2014-07-01

    Full Text Available In the face of higher costs of operation and increasing pressures from customers for better service, the logistics organization must adapt to meet the challenge. An understanding of the factors that make organizations effective, and a knowledge of how these factors interrelate, are the first steps towards developing the system for a firm’s customers. Logistics organizations must of necessity become more cost and service efficient. An understanding of the factors that affect a firm’s organizational effectiveness, along with strategies to reveal weaknesses or deficiencies, can help create more efficient logistics systems. Organizational changes form the basis for procedural modifications that can reduce costs or improve service. Many firms have shown significant improvements in their logistics cost-service mix as a result of organizational changes. Logistics organizations are generally structured along the following lines: strategic versus operational, centralized versus decentralized and line versus staff, in various combinations. There is no single ideal organizational structure, but there are important elements that comprise an effective organization. In general, the factors contributing to organizational effectiveness can be categorized as organizational characteristics, environmental characteristics, employee characteristics, and managerial policies and practices.

    2017-10-01

    Full Text Available Abstract Based on the CCR model, we propose an extended data envelopment analysis to evaluate the efficiency of decision making units with historical input and output data. The contributions of the work are threefold. First, the input and output data of the evaluated decision making unit are variable over time, and time series method is used to analyze and predict the data. Second, there are many sample decision making units, which are divided into several ordered sample standards in terms of production strategy, and the constraint condition consists of one of the sample standards. Furthermore, the efficiency is illustrated by considering the efficiency relationship between the evaluated decision making unit and sample decision making units from constraint condition. Third, to reduce the computation complexity, we introduce an algorithm based on the binary search tree in the model to choose the sample standard that has similar behavior with the evaluated decision making unit. Finally, we provide two numerical examples to illustrate the proposed model.

  12. Improving policy making through government-industry policy learning: The case of a novel Swedish policy framework

    International Nuclear Information System (INIS)

    Stigson, Peter; Dotzauer, Erik; Yan Jinyue

    2009-01-01

    Climate change poses an unprecedented challenge for policy makers. This paper analyzes how industry sector policy expertise can contribute to improved policy making processes. Previous research has identified that policy making benefit by including non-governmental policy analysts in learning processes. Recent climate and energy policy developments, including amendments and the introduction of new initiatives, have rendered current policy regimes as novel to both governments and the industry. This increases business investment risk perceptions and may thus reduce the effectiveness and efficiency of the policy framework. In order to explore how government-industry policy learning can improve policy making in this context, this article studied the Swedish case. A literature survey analyzed how policy learning had been previously addressed, identifying that the current situation regarding novel policies had been overlooked. Interviews provided how industrial actors view Swedish policy implementation processes and participatory aspects thereof. The authors conclude that an increased involvement of the industry sector in policy design and management processes can be an important measure to improve the effectiveness and efficiency of climate and energy policies

    Science.gov (United States)

    Goulet-Kennedy, Julie; Labbe, Sara; Fecteau, Shirley

    2016-01-01

    Decision making has been extensively studied in the context of economics and from a group perspective, but still little is known on individual decision making. Here we discuss the different cognitive processes involved in decision making and its associated neural substrates. The putative conductors in decision making appear to be the prefrontal cortex and the striatum. Impaired decision-making skills in various clinical populations have been associated with activity in the prefrontal cortex and in the striatum. We highlight the importance of strengthening the degree of integration of both cognitive and neural substrates in order to further our understanding of decision-making skills. In terms of cognitive paradigms, there is a need to improve the ecological value of experimental tasks that assess decision making in various contexts and with rewards; this would help translate laboratory learnings into real-life benefits. In terms of neural substrates, the use of neuroimaging techniques helps characterize the neural networks associated with decision making; more recently, ways to modulate brain activity, such as in the prefrontal cortex and connected regions (eg, striatum), with noninvasive brain stimulation have also shed light on the neural and cognitive substrates of decision making. Together, these cognitive and neural approaches might be useful for patients with impaired decision-making skills. The drive behind this line of work is that decision-making abilities underlie important aspects of wellness, health, security, and financial and social choices in our daily lives. PMID:27069380

    2012-07-01

    Much research has examined women's decision-making behaviour in breast cancer care. Patient age has shaped preferences, values, decision style and participation in treatment decisions. The aim of this study was to test the validity of the Michigan Assessment of Decision Style (MADS) (Pierce, 1995) in an older cohort and provide information on decision styles to identify areas of tailored decision support necessary for Israeli women. This study examined the decision-making styles of older Israeli women receiving routine mammography screening. Fifty two women over 65 years of age, attending a routine mammography screening, were administered a questionnaire containing demographic information and the MADS to determine hypothetical treatment decision-making. The MADS is a 16-item questionnaire assessing decision-making behaviour by characterizing four factors: avoiding, deferring, information-seeking and deliberation. Age, family history of breast cancer, and having a current mammography were not significantly associated with any of the four MADS factors. Deliberation and Deferring had the highest mean scores, followed closely by Information-Seeking and Avoidance. Correlations among the factors indicate a significant, positive correlation between Deliberation and Information-Seeking and a significant negative correlation between Deliberation and Deferring, consistent with previous studies. These findings indicate that older Israeli women's decision style is characterized by information seeking and deliberation reflecting a disposition towards engagement. The findings contribute to clinicians' understanding of women's preferences by countering the traditionally accepted stereotype that older women will employ a passive role when faced with an important health care decision.

    Full Text Available The present study was conducted to find out the level of job satisfaction and stress among Iranian EFL teachers. More precisely, an attempt was made to investigate the main sources of EFL teachers’ stress, their level of satisfaction with the job and the relationship between occupational stress and instructors’ age, marital status and tenure. Using a localized self-reported questionnaire, adapted from Ferguson, Frost, and Hall (2012, data was collected from 149 EFL teachers working in Urmia, Iran. The analysis of the data revealed that 29.93% of the teachers reported feelings of stress in one way or another. In addition, more than one-third of the teachers claimed to be somewhat or very dissatisfied with their job. It was also observed that age, marital status and employment play significant roles in the level of occupational stress perceived by EFL teachers. Suggestions are offered for relieving teachers from stress and how teacher education programmes can contribute.

    historic” view in the eyes of many. Therefore a different approach for establishing expected success was needed. The specific, pivotal round of deciding about the concept of a strategic vision is called here effective, if the agreed strategy as resulting from that round of decision-making is expected to eventually perform. But effectiveness of decision-making is not sufficient; an effective strategy also implies a new promising perspective for the development of a territory. Effective decision-making consisting of effective continuation of an existing trend or more efficiently deciding on a concept does not need a strategic development vision. Those activities are not considered here for effective strategy making. Therefore, the third exploration for composing our strategic frame focused on creativity as a requirement for discovering a novel direction of development. Discovering new possibilities for developments and re-interpreting existing qualities for new applications require an open creative approach. Design is needed for expanding the possibilities of what society sees as a probable future and above all for avoiding that the search for innovation would be restricted to what important actors consider possible. Central is the search for agreement about a desired future and how to make it possible. A process of co-designing a new vision of the desired future, whereby participating actors become co-authors of something not-existing before is assumed to bring about stronger and longer lasting commitment, which is essential for the long-term success. The assumed larger commitment would result from the combination of a maximal open process of decision-making like in designing, in which ideas of every participant are welcomed as valuable contributions and which takes the freedom of not starting by accepting limitations and conditions as coming from several sides. Such creative process is expected entailing forms of co-authorship. Important is that the relevant higher government

    The framing effect refers the tendency to be risk-averse when options are presented positively but be risk-seeking when the same options are presented negatively during decision-making. This effect has been found to be modulated by the serotonin transporter gene (SLC6A4) and the catechol-o-methyltransferase gene (COMT) polymorphisms, which are on the dopaminergic and serotonergic pathways and which are associated with affective processing. The current study aimed to identify new genetic variations of genes on dopaminergic and serotonergic pathways that may contribute to individual differences in the susceptibility to framing. Using genome-wide association data and the gene-based principal components regression method, we examined genetic variations of 26 genes on the pathways in 1317 Chinese Han participants. Consistent with previous studies, we found that the genetic variations of the SLC6A4 gene and the COMT gene were associated with the framing effect. More importantly, we demonstrated that the genetic variations of the aromatic-L-amino-acid decarboxylase (DDC) gene, which is involved in the synthesis of both dopamine and serotonin, contributed to individual differences in the susceptibility to framing. Our findings shed light on the understanding of the genetic basis of affective decision-making. © The Author (2017). Published by Oxford University Press.

  20. Tax Compliance and Social Security Contributions – The Case Of Slovenia

    2014-06-01

    Full Text Available In this paper, we will examine the causes behind the higher level of compliance with social security contributions in comparison with other tax categories in the case of Slovenia. The results of econometric models suggest that the activities of the Tax Administration of the Republic of Slovenia, which were more stringently performed in the area of social security contributions in the most recent period, are an important – but not the only factor – behind the higher level of compliance in connection with social security contributions. At the same time, the decrease in tax compliance with other taxes (income tax, corporate income tax, and VAT did not essentially influence the higher level of compliance with social security contributions. The more consistent treatment of unpaid social security contributions as a criminal offence and the higher public awareness about the importance of paying social security contributions in the latest period are recognized as important factors which simultaneously constitute the main difference between social security contributions and other taxes. The higher level of public awareness about the benefits that result from public services financed with taxes is recognized as a possible way to more optimally collect taxes in Slovenia.

    2014-01-01

    Teaching, as a social justice project, seeks to undo and re-imagine oppressive pedagogies in order to transform teachers, their students, and the knowledge with which they work. In this article, I argue that self-study can contribute to social justice in a number of ways by, for instance, making the sometimes limiting norms that frame teaching and…

    The neocortex contains orderly topographic maps; however, their functional role remains controversial. Theoretical studies have suggested a role in minimizing computational costs, whereas empirical studies have focused on spatial localization. Using a tactile multiple-choice reaction time (RT) task before and after the induction of perceptual learning through repetitive sensory stimulation, we extend the framework of cortical topographies by demonstrating that the topographic arrangement of intracortical inhibition contributes to the speed of human perceptual decision-making processes. RTs differ among fingers, displaying an inverted U-shaped function. Simulations using neural fields show the inverted U-shaped RT distribution as an emergent consequence of lateral inhibition. Weakening inhibition through learning shortens RTs, which is modeled through topographically reorganized inhibition. Whereas changes in decision making are often regarded as an outcome of higher cortical areas, our data show that the spatial layout of interaction processes within representational maps contributes to selection and decision-making processes.

    Understanding how individual identity is processed from faces remains a complex problem. Contrast reversal, showing faces in photographic negative, impairs face recognition in humans and demonstrates the importance of surface-based information (shading and pigmentation) in face recognition. We tested the importance of contrast information for face encoding in chimpanzees and rhesus monkeys using a computerized face-matching task. Results showed that contrast reversal (positive to negative) selectively impaired face processing in these two species, although the impairment was greater for chimpanzees. Unlike chimpanzees, however, monkeys performed just as well matching negative to positive faces, suggesting that they retained some ability to extract identity information from negative faces. A control task showed that chimpanzees, but not rhesus monkeys, performed significantly better matching face parts compared with whole faces after a contrast reversal, suggesting that contrast reversal acts selectively on face processing, rather than general visual-processing mechanisms. These results confirm the importance of surface-based cues for face processing in chimpanzees and humans, while the results were less salient for rhesus monkeys. These findings make a significant contribution to understanding the evolution of cognitive specializations for face processing among primates, and suggest potential differences between monkeys and apes.

    The objective of this study is to investigate the role and experience of early stage non-small cell lung cancer (NSCLC) patient in decision making process concerning treatment selection in the current clinical practice. Stage I-II NSCLC patients (surgery 55 patients, SBRT 29 patients, median age 68) were included in this prospective study and completed a questionnaire that explored: (1) perceived patient knowledge of the advantages and disadvantages of the treatment options, (2) experience with current clinical decision making, and (3) the information that the patient reported to have received from their treating physician. This was assessed by multiple-choice, 1-5 Likert Scale, and open questions. The Decisional Conflict Scale was used to assess the decisional conflict. Health related quality of life (HRQoL) was measured with SF-36 questionnaire. In 19% of patients, there was self-reported perceived lack of knowledge about the advantages and disadvantages of the treatment options. Seventy-four percent of patients felt that they were sufficiently involved in decision-making by their physician, and 81% found it important to be involved in decision making. Forty percent experienced decisional conflict, and one-in-five patients to such an extent that it made them feel unsure about the decision. Subscores with regard to feeling uninformed and on uncertainty, contributed the most to decisional conflict, as 36% felt uninformed and 17% of patients were not satisfied with their decision. HRQoL was not influenced by patient experience with decision-making or patient preferences for shared decision making. Dutch early-stage NSCLC patients find it important to be involved in treatment decision making. Yet a substantial proportion experiences decisional conflict and feels uninformed. Better patient information and/or involvement in treatment-decision-making is needed in order to improve patient knowledge and hopefully reduce decisional conflict.

    Productivity rate of rice fields in Regency has been in a surplus condition annually. The fields have produced 7 to 8 tons per hectare, making the total annual rate of 600 tons. The regency, therefore, is considered to be capable of fulfilling its own need for rice and to contribute significantly to the rice needs in Central Java Province. Agriculture coexists with the presence of pesticides. While helping the farmers to combat the plant diseases, pesticides have still been greatly necessary by the local farmers. Distribution by means of transportation devices plays an important role for the dissemination of the pesticides from the producers to their end users. Problem arises due to emission produced during the transportation activities. Transportation emits SO2 as the major contributor to acid rain. To make worse, application in practice by the farmers also emit the similar substance. Annual use of pesticides in Pati Regency has reached 605 tons with SO2 emission of 13,697 kg. It is recommended that distribution management and selection of pesticides are performed by applying an integrated pest control in order to reduce the pesticide emission.

  10. Reactivation of Reward-Related Patterns from Single Past Episodes Supports Memory-Based Decision Making.

    2016-03-09

    Rewarding experiences exert a strong influence on later decision making. While decades of neuroscience research have shown how reinforcement gradually shapes preferences, decisions are often influenced by single past experiences. Surprisingly, relatively little is known about the influence of single learning episodes. Although recent work has proposed a role for episodes in decision making, it is largely unknown whether and how episodic experiences contribute to value-based decision making and how the values of single episodes are represented in the brain. In multiple behavioral experiments and an fMRI experiment, we tested whether and how rewarding episodes could support later decision making. Participants experienced episodes of high reward or low reward in conjunction with incidental, trial-unique neutral pictures. In a surprise test phase, we found that participants could indeed remember the associated level of reward, as evidenced by accurate source memory for value and preferences to re-engage with rewarded objects. Further, in a separate experiment, we found that high-reward objects shown as primes before a gambling task increased financial risk taking. Neurally, re-exposure to objects in the test phase led to significant reactivation of reward-related patterns. Importantly, individual variability in the strength of reactivation predicted value memory performance. Our results provide a novel demonstration that affect-related neural patterns are reactivated during later experience. Reactivation of value information represents a mechanism by which memory can guide decision making. Copyright © 2016 the authors 0270-6474/16/362868-13$15.00/0.

  11. Doing Fieldwork on State Organizations in Democratic Settings: Ethical Issues of Research in Refugee Decision Making

    Directory of Open Access Journals (Sweden)

    Sule Tomkinson

    2014-11-01

    Full Text Available By drawing on eighteen months of ethnographic fieldwork and my field diaries in refugee decision-making in Canada, I make three arguments in this article. First, the binary of research in closed vs. open settings may have contributed to overlooking of ethical challenges of research in state organizations in democratic settings. We have to overcome this binary by opening a dialogue among ethnographers. Second, despite well-developed and diverse nature of scholarship on Research Ethics' Board's (REB formal practices and their negative impact on ethnographers' research proposals, the scarcity of scholarship on "ethics in practice" or "everyday ethics" show that we seem to forget that ethnographers, after receiving research ethics approval, still have to do considerable interpretation for what "being ethical" means. Finally, paying attention to "ethically important moments" during research practice may help us bridge the gap between principles of formal ethics and ethics in practice. Using field diaries in these reflections instead of more sanitized subsequent accounts illustrates the immediacy and importance of ethical concerns during research practice.

  12. Exchange current contributions to quasi-elastic electron scattering

    1981-01-01

    Because electromagnetic interactions are weak and well understood, inelastic electron scattering has been very useful in elucidating aspects of nuclear structure. In the region of large electron energy loss, an extremely simple reaction picture (quasi-free knockout of a single nucleon or electroproduction of an isobar) and a simple nuclear model (Fermi gas) have provided both a good fit to experimental data and a dynamical determination of the nuclear Fermi momentum (k/sub F/). However, there exists an anomalous region where this picture fails. Two body correlations have not seemed to help give any better agreement. We have investigated the following questions: Do exchange current processes contribute importantly in this region. Do they help produce agreement with experiment. Also, how do they effect our previous picture of quasifree knockout. We calculate the effects of exchange currents in this region using the standard Feynman graph rules. We have included all important long range exchange currents: pair, pionic, and isobar exchange currents. We found it necessary to make non-relativistic reductions of these currents in order to facilitate calculations. The resulting multidimensional integrals were done using Monte Carlo techniques. All exchange currents which were investigated were found to be appreciable in the anomalous region, and also important in the quasi-free peak region. Inclusion of these amplitudes would supply all of the missing cross section in the anomalous region: however, it would destroy the agreement between theory and experiment in the region of the quasi-free nucleon peak, and thereby cast suspicion on the aforementioned dynamical determination of k/sub F/

    Through the literature review we developed two analysis levels. On one side, the discussions points of these authors with Marxist economism, the commonalities and differences between them and their main conceptual contributions in the construction of a critical Marxism. On the other side, we develop the influence of Gramsci in anthropology, which interpretations have been made by this author?, the role played by the British Marxism in these interpretations and the specific contributions that anthropology could make to build Marxism not economicist.

  14. Strategic control in decision-making under uncertainty.

    2012-04-01

    Complex economic decisions - whether investing money for retirement or purchasing some new electronic gadget - often involve uncertainty about the likely consequences of our choices. Critical for resolving that uncertainty are strategic meta-decision processes, which allow people to simplify complex decision problems, evaluate outcomes against a variety of contexts, and flexibly match behavior to changes in the environment. In recent years, substantial research has implicated the dorsomedial prefrontal cortex (dmPFC) in the flexible control of behavior. However, nearly all such evidence comes from paradigms involving executive function or response selection, not complex decision-making. Here, we review evidence that demonstrates that the dmPFC contributes to strategic control in complex decision-making. This region contains a functional topography such that the posterior dmPFC supports response-related control, whereas the anterior dmPFC supports strategic control. Activation in the anterior dmPFC signals changes in how a decision problem is represented, which in turn can shape computational processes elsewhere in the brain. Based on these findings, we argue for both generalized contributions of the dmPFC to cognitive control, and specific computational roles for its subregions depending upon the task demands and context. We also contend that these strategic considerations are likely to be critical for decision-making in other domains, including interpersonal interactions in social settings. © 2012 The Authors.

    There is considerable interest in identifying national contributions to global warming as a way of allocating historical responsibility for observed climate change. This task is made difficult by uncertainty associated with national estimates of historical emissions, as well as by difficulty in estimating the climate response to emissions of gases with widely varying atmospheric lifetimes. Here, we present a new estimate of national contributions to observed climate warming, including CO 2 emissions from fossil fuels and land-use change, as well as methane, nitrous oxide and sulfate aerosol emissions While some countries’ warming contributions are reasonably well defined by fossil fuel CO 2 emissions, many countries have dominant contributions from land-use CO 2 and non-CO 2 greenhouse gas emissions, emphasizing the importance of both deforestation and agriculture as components of a country’s contribution to climate warming. Furthermore, because of their short atmospheric lifetime, recent sulfate aerosol emissions have a large impact on a country’s current climate contribution We show also that there are vast disparities in both total and per-capita climate contributions among countries, and that across most developed countries, per-capita contributions are not currently consistent with attempts to restrict global temperature change to less than 2 °C above pre-industrial temperatures.

    Full Text Available Abstract Background In addition to mediating the integration process, HIV-1 integrase (IN has also been implicated in different steps during viral life cycle including reverse transcription and viral DNA nuclear import. Although the karyophilic property of HIV-1 IN has been well demonstrated using a variety of experimental approaches, the definition of domain(s and/or motif(s within the protein that mediate viral DNA nuclear import and its mechanism are still disputed and controversial. In this study, we performed mutagenic analyses to investigate the contribution of different regions in the C-terminal domain of HIV-1 IN to protein nuclear localization as well as their effects on virus infection. Results Our analysis showed that replacing lysine residues in two highly conserved tri-lysine regions, which are located within previously described Region C (235WKGPAKLLWKGEGAVV and sequence Q (211KELQKQITK in the C-terminal domain of HIV-1 IN, impaired protein nuclear accumulation, while mutations for RK263,4 had no significant effect. Analysis of their effects on viral infection in a VSV-G pseudotyped RT/IN trans-complemented HIV-1 single cycle replication system revealed that all three C-terminal mutant viruses (KK215,9AA, KK240,4AE and RK263,4AA exhibited more severe defect of induction of β-Gal positive cells and luciferase activity than an IN class 1 mutant D64E in HeLa-CD4-CCR5-β-Gal cells, and in dividing as well as non-dividing C8166 T cells, suggesting that some viral defects are occurring prior to viral integration. Furthermore, by analyzing viral DNA synthesis and the nucleus-associated viral DNA level, the results clearly showed that, although all three C-terminal mutants inhibited viral reverse transcription to different extents, the KK240,4AE mutant exhibited most profound effect on this step, whereas KK215,9AA significantly impaired viral DNA nuclear import. In addition, our analysis could not detect viral DNA integration in each C

    2015-12-15

    A key question within systems neuroscience is how the brain translates physical stimulation into a behavioral response: perceptual decision making. To answer this question, it is important to dissociate the neural activity underlying the encoding of sensory information from the activity underlying the subsequent temporal integration into a decision variable. Here, we adopted a decoding approach to empirically assess this dissociation in human magnetoencephalography recordings. We used a functional localizer to identify the neural signature that reflects sensory-specific processes, and subsequently traced this signature while subjects were engaged in a perceptual decision making task. Our results revealed a temporal dissociation in which sensory processing was limited to an early time window and consistent with occipital areas, whereas decision-related processing became increasingly pronounced over time, and involved parietal and frontal areas. We found that the sensory processing accurately reflected the physical stimulus, irrespective of the eventual decision. Moreover, the sensory representation was stable and maintained over time when it was required for a subsequent decision, but unstable and variable over time when it was task-irrelevant. In contrast, decision-related activity displayed long-lasting sustained components. Together, our approach dissects neuro-anatomically and functionally distinct contributions to perceptual decisions.

    Full Text Available Country of origin is an important factor in product evaluation process as well as for purchase decision. Its importance depends on the amount of information consumers have about the product and product category. This paper investigates the importance of coutry of origin in purchase decision-making process for three different product categories: high risk and high level of consumer involvement in purchasing process (car, medium risk and midium level of consumer involvement in purchasing process (TV, and low risk and low level of consumer involvement in purchasing process (confectionery products. Also, this paper investigates importance of country of manufacturing for purchase decision-making process in relation to country of origin’s importance. Research was conducted on 215 respondents from Belgium and Republic of Croatia. Results have shown that country of origin is important only for car purchase, but not for TV and confectionery products. For all product categories, country of origin has been shown to be more important in the decision-making process than country of manufacturing.

    2003-01-01

    Objective: While psychology is accepted as a necessary component of the dementia diagnostics, the extended clinical diagnostics with neuroimaging is differently estimated. The goal of the study is the quantification of the individual contribution of the two different methods. Methods: Of 100 patient the diagnosis of entrance, the neurological, the psychological, and the final clinical diagnosis were documented. For both imaging and psychology the sensitivity, specificity, and the positive predictive value were computed. The diagnostic of each method was determined from the change of the final in relation to the initial clinical diagnosis. The neuroradiological investigation took place with MRI, the psychological examination used both usual power and special speed tests. Results: The extended clinical diagnostics led for 26% of the patients to the change of the clinical diagnosis. Imaging and psychology supplied different own but supplementing contributions. In the case of annihilation imaging contributed with 73.3%, psychology with 54.1% to the diagnosis of a neurodegenerative dementia, whereas the contributions to the diagnosis of a vascular dementia were 83.3% and 70.8%, respectively. However psychology diagnosed and quantified the dementia. The contribution of neuroimaging consisted in the differential diagnosis of the dementias organic causes of symptomatic clementias and vascular encephalopathy without dementia but with consequences for a secondary prophylaxis were additional information also. Conclusion: Psychology improves the diagnostic accuracy of dementias. Neuroimaging improves the differential diagnosis of dementias and supplies additional clinically relevant findings. In the qualified diagnostics and differential diagnostics of the dementias both methods are indispensable. (orig.) [de

  8. Mental Disorders and Decision-Making Capacity: What Is the Role of Law?

    Science.gov (United States)

    Rommelaere, Claire

    2015-03-01

    When a patient appears to have a mental disorder, doubts may arise about his or her decision-making capacity. Health professionals must then assess the patient's capacity in order to make sure of the validity of his or her consent or refusal. Incapacity has indeed legal consequences, as law provides for the appointment of a surrogate decision-maker in case of incapacity. With Belgian law as a point of departure, this contribution is aiming at identifying the role of law in capacity assessment itself, prior to the decision about (in)capacity. In order to protect the patient's rights and to support the task of those carrying out the assessment, law should provide for a global definition of decigion-making capacity and for a frame-procedure guiding this assessment. In my opinion, it is possible for law to contribute to the complex task of capacity assessment without interfering embarrassingly with healthcare practice.

  9. Greenhouse effect contributions of US landfill methane

    The greenhouse effect has recently been receiving a great deal of scientific and popular attention. The term refers to a cause-and-effect relationship in which ''heat blanketing'' of the earth, due to trace gas increases in the atmosphere, is expected to result in global warming. The trace gases are increasing as the result of human activities. Carbon dioxide (CO 2 ) is the trace gas contributing most importantly to the ''heat blanketing'' and currently receives the most attention. Less widely recognized has been the high importance of methane (CH 4 ). Methane's contribution to the increased heat blanketing occurring since 1980 is estimated to be over a third as much as that of carbon dioxide. Gas from landfills has in turn been recognized to be a source of methane to the atmospheric buildup. However the magnitude of the landfill methane contribution, and the overall significance of landfill methane to the greenhouse phenomenon has been uncertain and the subject of some debate. (Author)

    2005-01-01

    While science provides reliable information to describe and understand the earth and its natural processes, it can contribute more. There are many important societal issues in which scientific information can play a critical role. Science can add greatly to policy and management decisions to minimize loss of life and property from natural and man-made disasters, to manage water, biological, energy, and mineral resources, and in general, to enhance and protect our quality of life. However, the link between science and decision-making is often complicated and imperfect. Technical language and methods surround scientific research and the dissemination of its results. Scientific investigations often are conducted under different conditions, with different spatial boundaries, and in different timeframes than those needed to support specific policy and societal decisions. Uncertainty is not uniformly reported in scientific investigations. If society does not know that data exist, what the data mean, where to use the data, or how to include uncertainty when a decision has to be made, then science gets left out -or misused- in a decision making process. This paper is about using Geospatial Decision Support Systems (GDSS) for quantitative policy analysis. Integrated natural -social science methods and tools in a Geographic Information System that respond to decision-making needs can be used to close the gap between science and society. The GDSS has been developed so that nonscientists can pose "what if" scenarios to evaluate hypothetical outcomes of policy and management choices. In this approach decision makers can evaluate the financial and geographic distribution of potential policy options and their societal implications. Actions, based on scientific information, can be taken to mitigate hazards, protect our air and water quality, preserve the planet's biodiversity, promote balanced land use planning, and judiciously exploit natural resources.

    Full Text Available According to the different behavior characteristics of knowledge contribution of enterprise employees, a multi-task principal-agent relationship of knowledge contribution between enterprise and employees is established based on principal-agent theory, analyzing staff’s knowledge contribution behavior of knowledge creation and knowledge participation. Based on this, a multi-task principal agent model for knowledge contribution of enterprise staff is developed to formulate the asymmetry of information in knowledge contribution Then, a set of incentive measures are derived from the theoretic model, aiming to prompt the knowledge contribution in enterprise. The result shows that staff’s knowledge creation behavior and positive participation behavior can influence and further promote each other Enterprise should set up respective target levels of both knowledge creation contribution and knowledge participation contribution and make them irreplaceable to each other. This work contributes primarily to the development of the literature on knowledge management and principal-agent theory. In addition, the applicability of the findings will be improved by further empirical analysis.

    The concentrations of eleven elements: Ca, Co, Cr, Cs, Fe, I, K, Se, Sr, Th and Zn were determined in total diet samples and also in individual food materials which constitute the typical Indian diet. Instrumental neutron activation analysis (INAA) and radiochemical neutron activation analysis (RNAA) were employed for the analysis. Whereas the elements Fe, Co, Cr, Se and Zn are important from the view point of their role in nutrition, the elements Cs, K, Sr and Th are of importance in radiation protection, and Ca and I have dual importance: both in nutrition as well as in radiation protection. Based on the analysis of twenty total diet samples, prepared as per the data on the dietary intake pattern of four provinces of India and the data on intake pattern of an average adult Indian, the geometric mean (GM) intake of various elements was estimated to be 0.33 g (0.2-0.67) for Ca, 16.5 μg (8.3-31.1) for Co, 52.3μg (35.1-131) for Cr, 4.7μg (2.79-11.8) for Cs, 94.6μg (60.6-201) for I, 1.90 g (1.25-3.54) for K, 1.13 mg (0.78-2.97) for Sr, 0.76μg (0.45-1.66) for Th, 15.9 mg (10.2-34.3) for Fe, 56.3μg (27.6-105.3) for Se and 8.6 mg (5.1-16.7) for Zn. Some of the important individual food materials, such as cereals, pulses, milk, vegetables etc., were also analysed for these elements to observe the contributions of the individual food materials to their daily dietary intake. The results of the analysis showed that in the case of Cs, K, Sr, Th, Fe, Zn and Co, almost 50% of the daily dietary intake of the above stated elements is contributed by cereals and pulses. In the case of Ca however, significant amount is amount is contributed by milk and in case of I, iodised salt could make significant contribution. The data collected so far, for Se and Cr, was not sufficient to draw any definite conclusion. (author)

    To establish the outcomes achieved by using an innovative movie-making programme designed to reduce fear of radiotherapy among paediatric patients. Qualitative descriptive evaluation based on semistructured, qualitative interviews with purposeful sampling and thematic analysis. Tertiary Cancer Centre. 20 parents of paediatric patients who had produced a movie of their radiation therapy experience and were in a follow-up phase of cancer management. Participants attributed a broad range of outcomes to the movie-making program. These included that the programme had helped reduce anxiety and distress exhibited by paediatric patients and contributed to a willingness to receive treatment. Other outcomes were that the completed movies had been used in school reintegration and for maintaining social connections. Allowing children to create a video of their experience of radiotherapy provided a range of benefits to paediatric patients that varied according to their needs. For some patients, movie-making offered a valuable medium for overcoming fear of the unknown as well as increasing understanding of treatment processes. For others, the development of a personalised video offered an important cognitive/attentional distraction through engaging with an age-appropriate activity. Together these outcomes helped children maintain self-control and a positive outlook.

  15. What makes virtual agents believable?

    2016-01-01

    In this paper we investigate the concept of believability and make an attempt to isolate individual characteristics (features) that contribute to making virtual characters believable. As the result of this investigation we have produced a formalisation of believability and based on this formalisation built a computational framework focused on simulation of believable virtual agents that possess the identified features. In order to test whether the identified features are, in fact, responsible for agents being perceived as more believable, we have conducted a user study. In this study we tested user reactions towards the virtual characters that were created for a simulation of aboriginal inhabitants of a particular area of Sydney, Australia in 1770 A.D. The participants of our user study were exposed to short simulated scenes, in which virtual agents performed some behaviour in two different ways (while possessing a certain aspect of believability vs. not possessing it). The results of the study indicate that virtual agents that appear resource bounded, are aware of their environment, own interaction capabilities and their state in the world, agents that can adapt to changes in the environment and exist in correct social context are those that are being perceived as more believable. Further in the paper we discuss these and other believability features and provide a quantitative analysis of the level of contribution for each such feature to the overall perceived believability of a virtual agent.

    Wild and managed bees are well documented as effective pollinators of global crops of economic importance. However, the contributions by pollinators other than bees have been little explored despite their potential to contribute to crop production and stability in the face of environmental change. Non-bee pollinators include flies, beetles, moths, butterflies, wasps, ants, birds, and bats, among others. Here we focus on non-bee insects and synthesize 39 field studies from five continents that directly measured the crop pollination services provided by non-bees, honey bees, and other bees to compare the relative contributions of these taxa. Non-bees performed 25-50% of the total number of flower visits. Although non-bees were less effective pollinators than bees per flower visit, they made more visits; thus these two factors compensated for each other, resulting in pollination services rendered by non-bees that were similar to those provided by bees. In the subset of studies that measured fruit set, fruit set increased with non-bee insect visits independently of bee visitation rates, indicating that non-bee insects provide a unique benefit that is not provided by bees. We also show that non-bee insects are not as reliant as bees on the presence of remnant natural or seminatural habitat in the surrounding landscape. These results strongly suggest that non-bee insect pollinators play a significant role in global crop production and respond differently than bees to landscape structure, probably making their crop pollination services more robust to changes in land use. Non-bee insects provide a valuable service and provide potential insurance against bee population declines.

  17. Use of Human Reliability Insights to Improve Decision-Making

    Julius, J. A.; Moieni, P.; Grobbelaar, J.; Kohlhepp, K.

    2016-01-01

    This paper describes the use of insights obtained during the development and application of human reliability analysis (HRA) as part of a probabilistic risk assessment (PRA) to support decision-making, including improvements to operations, training, and safety culture. Insights have been gained from the development and application of HRA as part of a PRA for nuclear power plants in the USA, Europe and Asia over the last two decades. These models consist of Level 1 and Level 2 PRA models of internal and external events, during full power and shutdown modes of plant operation. These insights include the use of human factors information to improve the qualitative portion of the HRA. The subsequent quantification in the HRA effectively prioritises the contributors to the unreliability of operator actions, and the process facilitates the identification of the factors that are important to the success of the operator actions. Additionally, the tools and techniques also allow for the evaluation of key assumptions and sources of uncertainty. The end results have been used to effectively support decision-making for day-to-day plant operations as well as licensing issues. HRA results have been used to provide feedback and improvements to plant procedures, operator training and other areas contributing the plant safety culture. Examples of the types of insights are presented in this paper. (author)

  18. The Impact of Sexual Arousal on Sexual Risk-Taking and Decision-Making in Men and Women.

    2016-01-01

    Sexual arousal has emerged as an important contextual feature in sexual encounters that can impact safer-sex decision-making. We conducted two experiments that investigated the effects of sexual arousal among male and female participants. Experiment 1 (N = 144) examined the impact of sexual around on sexual health decision-making. Sexually explicit and neutral video clips as well as hypothetical romantic scenarios were used to evaluate the effects of sexual arousal on sexual risk-taking intentions. Men and women who reported higher levels of sexual arousal also displayed greater intentions to participate in risky sexual behavior (e.g., unprotected sex with a new sex partner). Experiment 2 (N = 122) examined the impact of sexual arousal on general risk-taking, using the same videos clips as in Experiment 1 and a modified version of a computerized Blackjack card game. Participants were offered a chance to make either a risky play or a safe play during ambiguous conditions. Increased sexual arousal in Experiment 2 was associated with impulsivity and a greater willingness to make risky plays in the Blackjack game. These findings suggest that, in situations where there are strong sexually visceral cues, both men and women experiencing strong sexual arousal may have lower inhibitions and may experience impaired decision-making. This phenomenon may have an impact during sexual encounters and may contribute to a failure to use appropriate prophylactic protection.

  1. Serotonin and decision making processes.

    Science.gov (United States)

    Homberg, Judith R

    2012-01-01

    Serotonin (5-HT) is an important player in decision making. Serotonergic antidepressant, anxiolytic and antipsychotic drugs are extensively used in the treatment of neuropsychiatric disorders characterized by impaired decision making, and exert both beneficial and harmful effects in patients. Detailed insight into the serotonergic mechanisms underlying decision making is needed to strengthen the first and weaken the latter. Although much remains to be done to achieve this, accumulating studies begin to deliver a coherent view. Thus, high central 5-HT levels are generally associated with improved reversal learning, improved attentional set shifting, decreased delay discounting, and increased response inhibition, but a failure to use outcome representations. Based on 5-HT's evolutionary role, I hypothesize that 5-HT integrates expected, or changes in, relevant sensory and emotional internal/external information, leading to vigilance behaviour affecting various decision making processes. 5-HT receptor subtypes play distinctive roles in decision making. 5-HT(2A) agonists and 5-HT2c antagonists decrease compulsivity, whereas 5-HT(2A) antagonists and 5-HT(2C) agonists decrease impulsivity. 5-HT(6) antagonists univocally affect decision making processes.

    Effort-based decision-making paradigms are increasingly utilized to gain insight into the nature of motivation deficits. Research has shown associations between effort-based decision making and experiential negative symptoms; however, the associations are not consistent. The current study had two primary goals. First, we aimed to replicate previous findings of a deficit in effort-based decision making among individuals with schizophrenia on a test of cognitive effort. Second, in a large sample combined from the current and a previous study, we sought to examine the association between negative symptoms and effort by including the related construct of defeatist beliefs. The results replicated previous findings of impaired cognitive effort-based decision making in schizophrenia. Defeatist beliefs significantly moderated the association between negative symptoms and effort-based decision making such that there was a strong association between high negative symptoms and deficits in effort-based decision making, but only among participants with high levels of defeatist beliefs. Thus, our findings suggest the relationship between negative symptoms and effort performance may be understood by taking into account the role of defeatist beliefs, and finding that might explain discrepancies in previous studies.

    Alexithymia is characterised by difficulties identifying and describing emotions. Few studies have investigated how alexithymia influences decision-making under different conditions (ambiguity and risk). This study aimed to examine whether alexithymia contributes to impairment in decision-making. This study included 42 participants with high scores in the Chinese version of Toronto Alexithymia Scale (alexithymia group), and 44 matched subjects with low scores (control group). Decision-making was measured using the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT). The main findings of this study revealed selective deficits in IGT performance for the alexithymia group, while GDT performance was unimpaired when compared with the control group. In IGT, total netscores were lower for the alexithymia group compared to the control group, particularly with regard to block 5. Moreover, the alexithymia individuals selected significantly more adverse cards than the controls, indicating significant decision-making impairments. Alexithymia selectively influences decision-making under ambiguity.

    Up to now, little attention has been paid to West Africa when it comes to shared decision making (SDM). West African countries seem to lag behind with regard to SDM initiatives compared to many other countries in the world. There is some interest in informed decision making or informed consent, but little in a full SDM process. Few decision-making tools are available for healthcare professionals and the majority are not designed to support decision-making with patients. Furthermore, to the best of our knowledge, there are no training programs for implementing SDM in healthcare teams. Many barriers exist to implementing SDM in West Africa, including lack of options, few or poor health resources and low levels of education. However, African countries present many opportunities for SDM as well. Existing SDM innovations developed for other populations with low literacy could be explored and adapted to the West African context, and research on implementation and outcomes in West Africa could contribute to SDM worldwide. West African countries are in an excellent position to both learn from other countries and contribute to SDM development in other parts of the world. In this paper we reflect on SDM challenges and opportunities, and propose a research agenda for West Africa. We hope to awaken interest in SDM in West Africa and encourage future collaborations on SDM with various West African stakeholders, including patients, healthcare professionals, policymakers, non-government organisations (NGOs) and academic institutions.

    It is the rational and exact computation of the safety economy contribution rate that has the far-reaching realistic meaning to the improvement of society cognition to safety and the investment to the nation safety and the national macro-safety decision-makings. The accurate function between safety inputs and outputs was obtained through a founded econometric model. Then the forecasted safety economy contribution rate is 3.01% and the forecasted ratio between safety inputs and outputs is 1:1.81 in China in 2005. And the model accords with the practice of China and the results are satisfying.

    Efforts to redesign primary care practices are beginning to address how decisions are made in the practice setting. This study contributes to these efforts by examining associations between staff participation in decision-making, productivity, and turnover in primary care practices. The study is informed by organizational theories of participation that emphasize cognitive and affective influences on employee output and behavior. This research used data collected from primary care practices involved in a national initiative sponsored by the Robert Wood Johnson Foundation. Cross-sectional survey data on organizational structures and attributes among 49 practices were analyzed. Regression analysis was used to examine associations among practice productivity, staff participation in decision-making, and formal structures such as staff meetings. Associations between staff turnover and participative decision-making were also examined. Staff participation in decisions regarding quality improvement, practice change, and clinical operations was positively associated with practice productivity, whereas formal structures such as staff meetings were not. In addition, higher levels of participation in decision-making were associated with reduced turnover among nonclinicians and administrative staff. Examination of organizational features is increasingly recognized as a key to improving primary care performance. Study findings suggest that one important strategy may be implementation of a participative model emphasizing greater staff involvement in practice decisions. This may enhance information-sharing, work satisfaction, and commitment to organizational decisions, all of which can lead to beneficial outcomes such as increased productivity and stability in primary care practices.

    Improving the quality and transparency of governmental healthcare decision-making has an impact on the health of the population through policies, organisational management and clinical practice. Moreover, the comparison between healthcare centres and the transparent feedback of results to professionals and to the wider public contribute directly to improved results. The "Results Centre" of the Catalan healthcare system measures and disseminates the results achieved by the different healthcare centres in order to facilitate a shared decision-making process, thereby enhancing the quality of healthcare provided to the population of Catalonia (Spain). This is a pioneering initiative in Spain and is aligned with the most advanced countries in terms of policies of transparency and accountability. Copyright © 2016 SESPAS.

    A revolution in the science of emotion has emerged in recent decades, with the potential to create a paradigm shift in decision theories. The research reveals that emotions constitute potent, pervasive, predictable, sometimes harmful and sometimes beneficial drivers of decision making. Across different domains, important regularities appear in the mechanisms through which emotions influence judgments and choices. We organize and analyze what has been learned from the past 35 years of work on emotion and decision making. In so doing, we propose the emotion-imbued choice model, which accounts for inputs from traditional rational choice theory and from newer emotion research, synthesizing scientific models.

    Both fresh and processed foods make up vital parts of the food supply. Processed food contributes to both food security (ensuring that sufficient food is available) and nutrition security (ensuring that food quality meets human nutrient needs). This ASN scientific statement focuses on one aspect of processed foods: their nutritional impacts. Specifically, this scientific statement 1) provides an introduction to how processed foods contribute to the health of populations, 2) analyzes the contribution of processed foods to "nutrients to encourage" and "constituents to limit" in the American diet as recommended by the Dietary Guidelines for Americans, 3) identifies the responsibilities of various stakeholders in improving the American diet, and 4) reviews emerging technologies and the research needed for a better understanding of the role of processed foods in a healthy diet. Analyses of the NHANES 2003-2008 show that processed foods provide both nutrients to encourage and constituents to limit as specified in the 2010 Dietary Guidelines for Americans. Of the nutrients to encourage, processed foods contributed 55% of dietary fiber, 48% of calcium, 43% of potassium, 34% of vitamin D, 64% of iron, 65% of folate, and 46% of vitamin B-12. Of the constituents to limit, processed foods contributed 57% of energy, 52% of saturated fat, 75% of added sugars, and 57% of sodium. Diets are more likely to meet food guidance recommendations if nutrient-dense foods, either processed or not, are selected. Nutrition and food science professionals, the food industry, and other stakeholders can help to improve the diets of Americans by providing a nutritious food supply that is safe, enjoyable, affordable, and sustainable by communicating effectively and accurately with each other and by working together to improve the overall knowledge of consumers. © 2014 American Society for Nutrition.

  15. A canonical theory of dynamic decision-making

    2013-04-01

    Full Text Available Decision-making behaviour is studied in many very different fields, from medicine and economics to psychology and neuroscience, with major contributions from mathematics and statistics, computer science, AI and other technical disciplines. However the conceptualisation of what decision-making is and methods for studying it vary greatly and this has resulted in fragmentation of the field. A theory that can accommodate various perspectives may facilitate interdisciplinary working. We present such a theory in which decision-making is articulated as a set of canonical functions that are sufficiently general to accommodate diverse viewpoints, yet sufficiently precise that they can be instantiated in different ways for specific theoretical or practical purposes. The canons cover the whole decision cycle, from the framing of a decision based on the goals, beliefs, and background knowledge of the decision maker to the formulation of decision options, establishing preferences over them, and making commitments. Commitments can lead to the initiation of new decisions and any step in the cycle can incorporate reasoning about previous decisions and the rationales for them, and lead to revising or abandoning existing commitments. The theory situates decision making with respect to other high-level cognitive capabilities like problem-solving, planning and collaborative decision-making. The canonical approach is assessed in three domains: cognitive and neuro-psychology, artificial intelligence, and decision engineering.

  17. Deformation-driven, lethal damage to cancer cells. Its contribution to metastatic inefficiency.

    Science.gov (United States)

    Weiss, L

    1991-04-01

    Direct and indirect, in vivo and in vitro observations are in accord with the hypothesis that as a consequence of their deformation within capillaries, cancer cells undergo sphere-to-cylinder shape-transformations that create a demand for increased surface area. When this demand cannot be met by apparent increases in surface area accomplished by nonlethal, surface "unfolding," the cell surface membrane is stretched; if expansion results in more than a 4% increase in true surface area, the membrane ruptures, resulting in cancer cell death. It is suggested that this deformation-driven process is an important factor in accounting for the rapid death of circulating cancer cells that have been trapped in the microvasculature. Therefore, this mechanism is thought to make a significant contribution to metastatic inefficiency by acting as a potent rate-regulator for hematogenous metastasis.

Neuroimaging studies suggest that this speed-accuracy tradeoff is implemented in a corticobasal ganglia network that includes an important contribution from the pre-SMA. To test this hypothesis, we used anodal transcranial direct current stimulation (tDCS) to modulate neural activity in pre-SMA while participants performed a simple perceptual decision-making task. Participants viewed a pattern of moving dots and judged the direction of the global motion. In separate trials, they were cued to either respond quickly or accurately. We used the diffusion decision model to estimate the response threshold parameter, comparing conditions in which participants received sham or anodal tDCS. In three independent experiments, we failed to observe an influence of tDCS on the response threshold. Additional, exploratory analyses showed no influence of tDCS on the duration of nondecision processes or on the efficiency of information processing. Taken together, these findings provide a cautionary note, either concerning the causal role of pre-SMA in decision-making or on the utility of tDCS for modifying response caution in decision-making tasks.

    As a prelude to separating tertiary from quaternary structure contributions to the Bohr effect, we employed the Wyman equation to analyze Bohr data for human hemoglobin to which 2,3-bisphosphoglycerate, 2,3-BPG, is bound. Changes in the pK a s of the histidine Bohr groups result in a net reduction of their contributions to the Bohr effect at pH 7.4 compared to their contributions in stripped hemoglobin. The non-histidine 2,3-BPG binding groups - the β-chain terminal amino group and Lys82β - make negative and positive contributions, respectively, to the Bohr effect. The final result is that the Bohr effect at physiological pH is higher for 2,3-BPG bound compared to stripped hemoglobin. Contributions linked to His2β, His77β and His143β enable us to separate tertiary from quaternary Bohr contributions in stripped and in 2,3-BPG bound hemoglobin. Both contributions serve to make the Bohr effect for 2,3-BPG bound hemoglobin higher than for stripped hemoglobin at physiological pH. Copyright © 2017 Elsevier B.V. All rights reserved.

    Millions of women have little health care decision making autonomy in many cultures and tribes. African women are often perceived to have little participation in health care decisions. However, little has been investigated to identify factors contributing to decision making autonomy. Hence, it is important to obtain information on the contributing factors of decision making autonomy and disparities across different socio-cultural contexts. A cross-sectional study was conducted in Wolaita and Dawro zones, Southern Ethiopia from February to March 2015. A total of 967 women were selected through multistage sampling. A survey was administered face-to-face through an interview format. EpiData v1.4.4.0 and SPSS version 20 were used to enter and analyze data, respectively. Proportions and means were used to describe the study population. Variables with P -value autonomy, while 40.9% of study participants' health care decisions were made by their husbands. The husband's education (adjusted odds ratio [AOR] =1.91 [1.10, 3.32]), wealth index (AOR =0.62 [0.42, 0.92]), age (AOR =2.42 [1.35, 4.32] and AOR =7 [3.45, 14.22]), family size (AOR =0.53 [0.33, 0.85] and AOR =0.42 [0.23, 0.75]), and occupation (AOR =1.66 [1.14, 2.41]), were predictors of health care decision making autonomy. Even though every woman has the right to participate in her own health care decision making, more than two fifths of them have no role in making health care decisions about their own health. Husbands play a major role in making health care decisions about their wives. A comprehensive strategy needs to be implemented in order to empower women, as well as to challenge the traditional male dominance. Special attention has to be given to women living in rural areas in order to reduce their dependency through education and income generating activities.

    The electron and positron contributions to the effective atom displacement cross-section in multi-walled carbon nanotube bulk materials exposed to gamma rays were calculated. The physical properties and the displacement threshold energy value reported in literature for this material were taken into account. Then, using the mathematical simulation of photon and particle transport in matter, the electron and positron energy flux distributions within the irradiated object were also calculated. Finally, considering both results, the atom displacement damage profiles inside the analyzed bulk carbon nanotube material were determined. The individual contribution from each type of secondary particles generated by the photon interactions was specified. An increasing behavior of the displacement cross-sections for all the studied particles energy range was observed. The particles minimum kinetic energy values that make probabilistically possible the single and multiple atom displacement processes were determined. The positrons contribution importance to the total number of point defects generated during the interaction of gamma rays with the studied materials was confirmed

    Social and decision-making deficits are often the first symptoms of a striking number of neurodegenerative disorders associated with aging. These includes not only disorders that directly impact dopamine and basal ganglia, such as Parkinson's disorder, but also degeneration in which multiple neural pathways are affected over the course of normal aging. The impact of such deficits can be dramatic, as in cases of financial fraud, which disproportionately affect the elderly. Unlike memory and motor impairments, however, which are readily recognized as symptoms of more serious underlying neurological conditions, social and decision-making deficits often do not elicit comparable concern in the elderly. Furthermore, few behavioral measures exist to quantify these deficits, due in part to our limited knowledge of the core cognitive components or their neurobiological substrates. Here we probe age-related differences in decision-making using a game theory paradigm previously shown to dissociate contributions of basal ganglia and prefrontal regions to behavior. Combined with computational modeling, we provide evidence that age-related changes in elderly participants are driven primarily by an over-reliance in trial-and-error reinforcement learning that does not take into account the strategic context, which may underlie cognitive deficits that contribute to social vulnerability in elderly individuals.

  3. Conductus makes high-Tc integrated circuit

    This paper reports that researchers at Conductus have successfully demonstrated what the company says is the world's first integrated circuit containing active devices made from high-temperature superconductors. The circuit is a SQUID magnetometer made from seven layers of material: three layers of yttrium-barium-copper oxide, two layers of insulating material, a seed layer to create grain boundaries for the Josephson junctions, and a layer of silver for making electrical contact to the device. The chip also contains vias, or pathways that make a superconducting contact between the superconducting layers otherwise separated by insulators. Conductus had previously announced the development of a SQUID magnetometer that featured a SQUID sensor and a flux transformer manufactured on separate chips. What makes this achievement important is that the company was able to put both components on the same chip, thus creating a simple integrated circuit on a single chip. This is still a long way from conventional semiconductor technology, with as many as a million components per chip, or even the sophisticated low-Tc superconducting chips made by the Japanese, but the SQUID magnetometer demonstrates all the elements and techniques necessary to build more complex high-temperature superconductor integrated circuits, making this an important first step

    2017-10-01

    The use of Geographic Information Systems (GIS) has spread to several science areas, from oceanography to geotechnics. Its application in the urban mapping was intensified in the last century, which allowed a great development, due to the use of geographic database, new analysis tools and, more recently, free open source software. Geotechnical cartography struggle with a permanent and large environment re-organization in urban area, due to new building construction, trenching and the drilling of sampling wells and holes. This creates an extra important and largest volume of data at any pre-existence geological map. The main problem results on the fact that the natural environment is covered with buildings and communications system. The purpose of this work is to create a viable geographic information base for geotechnical mapping through a free GIS computer program and open source, with non-traditional cartographic sources, giving preference to open platforms. QGIS was used as software and “Google Maps”, “Bing Maps” and “OpenStreetMap” were applied as cartographic sources using the “OpenLayers plugin” module. Finally, we also pretend to identify and delimit the degree of granite’s change and fracturing areas using a “Streetview” platform. This model has cartographic input which are a geological map study area, open cartographic web archives and the use of “Streetview” platform. The output has several layouts, such as topography intersection (roads, borders, etc.), with geological map and the bordering area of Guarda Urban Zone. The use of this platform types decrease the collect data time and, sometimes, a careful observation of pictures that were taken during excavations may reveal important details for geological mapping in the study area.

    Certified nursing assistants (CNAs) provide up to 80% of the direct care to older adults in long-term care facilities. CNAs are perceived as being at the bottom of the hierarchy among healthcare professionals often negatively affecting their job satisfaction. However, many CNAs persevere in providing quality care and even reporting high levels of job satisfaction. The aim of the present investigation was to identify primary themes that may help CNAs make meaning of their chosen career; thus potentially partially explaining increases in job satisfaction among this group. Focus groups were conducted with CNAs at three long-term care facilities. Four themes emerged from the data: CNA work is good or special; CNA as relationship builder; CNA as expert; CNA as team member. These themes reflect the perceptions that these CNAs held in regard to themselves and their relationships to others in the work environment and, when present, can contribute to intrinsic job satisfaction. Our meaning-making themes support the premise that CNAs do not passively accept the evaluations of others but instead actively frame identities that validate their importance to residents and the institution. © 2016 John Wiley & Sons Ltd.

    Full Text Available This paper attempts an empirical examination of the practicality of strategic management accounting (SMA adoption in banks in Nigeria, a developing country. It investigates the extent of practice and contributions of SMA to strategic decision making. Survey data were obtained from 71 bank managers across 20 registered banks in Nigeria. Simple regression estimation technique and Pearson Chi-square test were used for data analysis. The results suggest that SMA is distinct in its features and orientation towards the practice of management accounting. The study found out that banks in Nigeria practice SMA; not as a concept, but as a principle of operation, and that SMA contributes significantly to strategic decision making in the area of competitive advantage and increased market share. The study offers value for banks in other developing economies in that it supports the argument that they can benefit from SMA adoption as part of banking strategies.

    Breakfast is an important source of micronutrients in the diet and its consumption has been linked to positive health outcomes. The present analysis investigated the contribution that breakfast cereals make to the nutrient intakes of the materially deprived (low income) UK population. Data for 3728 respondents aged 2 years and over from the UK Low Income Diet and Nutrition Survey (2003-2005) were analysed. Nutrient intakes of consumers and non-consumers of breakfast cereal were compared. Breakfast cereals were consumed by 49% of men, 58% of women, 80% of boys and 80% of girls, and median intakes were: 35, 25, 29 and 21 g/d, respectively. Consumers of breakfast cereals had higher intakes of thiamin, riboflavin, niacin, biotin, folate, vitamin B(6), vitamin B(12), iron and zinc than non-consumers. Breakfast cereal consumption was also related to higher intakes of calcium, attributable to higher milk consumption. The intake of wholegrain and high-fibre breakfast cereals was associated with a higher intake of non-starch polysaccharides. Intakes of niacin, biotin, calcium and zinc were higher but that of vitamin B(6) was lower among consumers of exclusively wholegrain and high-fibre breakfast cereals compared with consumers of other breakfast cereals. There were no significant differences observed in intakes of non-milk extrinsic sugars according to type of breakfast cereal consumed. Breakfast cereals make a significant contribution to the micronutrient intake of the low-income UK population.

    Groundwater is one of the most important environmental resources and its use continuously rises globally for industrial, agricultural, and drinking water supply purposes. Because of its importance, more knowledge about the volume of usable groundwater is necessary to satisfy the global demand. Due to the challenges in quantifying the volume of available global groundwater, studies which aim to assess its magnitude are limited in number. They are further restricted in scope and depth of analysis as, in most cases, they do not explain how the estimates of global groundwater resources have been obtained, what methods have been used to generate the figures and what levels of uncertainty exist. This article reviews the estimates of global groundwater resources. It finds that the level of uncertainty attached to existing numbers often exceeds 100 % and strives to establish the reasons for discrepancy. The outcome of this study outlines the need for a new agenda in water research with a more pronounced focus on groundwater. This new research agenda should aim at enhancing the quality and quantity of data provision on local and regional groundwater stocks and flows. This knowledge enhancement can serve as a basis to improve policy-making on groundwater resources globally. Research-informed policies will facilitate more effective groundwater management practices to ensure a more rapid progress of the global water sector towards the goal of sustainability.

    Background For health technology assessment (HTA) to be more policy relevant and for health technology-related decision-making to be truly evidence-based, promoting knowledge translation (KT) is of vital importance. Although some research has focused on KT of HTA, there is a dearth of literature on KT determinants and the situation in developing countries and transitional societies remains largely unknown. Objective To investigate the determinants of HTA KT from research to health policy-making from the perspective of researchers in China. Design Cross-sectional study. Methods A structured questionnaire which focused on KT was distributed to HTA researchers in China. KT activity levels in various fields of HTA research were compared, using one-way ANOVA. Principal component analysis was performed to provide a basis to combine similar variables. To investigate the determinants of KT level, multiple linear regression analysis was performed. Results Based on a survey of 382 HTA researchers, it was found that HTA KT wasn’t widespread in China. Furthermore, results showed that no significant differences existed between the various HTA research fields. Factors, such as attitudes of researchers toward HTA and evidence utilization, academic ranks and linkages between researchers and policy-makers, had significant impact on HTA KT (p-valuespolicy-makers, policy-relevance of HTA research, practicality of HTA outcomes and making HTA reports easier to understand also contributed to predicting KT level. However, academic nature of HTA research was negatively associated with KT level. Conclusion KT from HTA to policy-making was influenced by many factors. Of particular importance were collaborations between researchers and policy-makers, ensuring policy relevance of HTA and making HTA evidence easier to understand by potential users. PMID:29300753

    The original Emancipated Decision-Making (EDM) scale was revised to test 3 subconcepts (flexible environment, personal knowledge, and awareness of social norms) of an emancipated decision-making process. The original EDM scale was significantly related to the Satisfaction with Decision (SWD) scale in two separate studies (r = 0.79, r = 0.59). Two of the original 5 subconcepts showed a lack of contribution. The third study (N = 50) had good total scale reliability (r = 0.89). The revised EDM (EDM-r) scale was then leveled to the SWD scores and quantified into 2 categories and the subscales for the 3 subconcepts were reanalyzed for reliability and scale-if-item contribution. The final EDM-r is a generically worded, 20-item, 3-subscale instrument with good total and individual subscale reliability.

    Organizational decision making is dominated by teams. When an important decision is required, a team is often formed to make it or to advise the individual decision maker, because a team has more resources, knowledge, and political insight than any one individual working alone.

    2014-12-01

    Recent neuroimaging studies on decision-making under risk indicate that the angular gyrus (AG) is sensitive to the probability and variance of outcomes during choice. A separate body of research has established the AG as a key area in visual attention. The current study used repetitive transcranial magnetic stimulation (rTMS) in healthy volunteers to test whether the causal contribution of the AG to decision-making is independent of or linked to the guidance of visuospatial attention. A within-subject design compared decision making on a laboratory gambling task under three conditions: following rTMS to the AG, following rTMS to the premotor cortex (PMC, as an active control condition) and without TMS. The task presented two different trial types, 'visual' and 'auditory' trials, which entailed a high versus minimal demand for visuospatial attention, respectively. Our results showed a systematic effect of rTMS to the AG upon decision-making behavior in visual trials. Without TMS and following rTMS to the control region, decision latencies reflected the odds of winning; this relationship was disrupted by rTMS to the AG. In contrast, no significant effects of rTMS to the AG (or to the PMC) upon choice behavior in auditory trials were found. Thus, rTMS to the AG affected decision-making only in the task condition requiring visuospatial attention. The current findings suggest that the AG contributes to decision-making by guiding attention to relevant information about reward and punishment in the visual environment. Copyright © 2014.

    Full Text Available Citation indexes are regarded as important factors to make an effective literature review. Since the publication on the SSCI has been a requirement for the academic degrees in Turkey, the value of scientific articles published in citation indexes has increased. Therefore, bibliometric values and the topic distribution of journals published in a specific discipline are of great importance especially for academicians working in the related discipline. This study will select ten journals that have the highest value of 5-year impact factor in the 2013 JCR among the journals published in Public Administration in SSCI and examine their quantitative and qualitative values. As a result of the research, it is intended to generate benefits for researchers that will work in the discipline of Public Administration through specifying the most contributing journals to the field and presenting subject headings and the distribution of topics in the selected journals.

  18. Contribution mapping: a method for mapping the contribution of research to enhance its impact

    Science.gov (United States)

    2012-01-01

    Background At a time of growing emphasis on both the use of research and accountability, it is important for research funders, researchers and other stakeholders to monitor and evaluate the extent to which research contributes to better action for health, and find ways to enhance the likelihood that beneficial contributions are realized. Past attempts to assess research 'impact' struggle with operationalizing 'impact', identifying the users of research and attributing impact to research projects as source. In this article we describe Contribution Mapping, a novel approach to research monitoring and evaluation that aims to assess contributions instead of impacts. The approach focuses on processes and actors and systematically assesses anticipatory efforts that aim to enhance contributions, so-called alignment efforts. The approach is designed to be useful for both accountability purposes and for assisting in better employing research to contribute to better action for health. Methods Contribution Mapping is inspired by a perspective from social studies of science on how research and knowledge utilization processes evolve. For each research project that is assessed, a three-phase process map is developed that includes the main actors, activities and alignment efforts during research formulation, production and knowledge extension (e.g. dissemination and utilization). The approach focuses on the actors involved in, or interacting with, a research project (the linked actors) and the most likely influential users, who are referred to as potential key users. In the first stage, the investigators of the assessed project are interviewed to develop a preliminary version of the process map and first estimation of research-related contributions. In the second stage, potential key-users and other informants are interviewed to trace, explore and triangulate possible contributions. In the third stage, the presence and role of alignment efforts is analyzed and the preliminary

    It has been shown that penguin diagram contributions corresponding to u-quark loop momenta below a scale Λsub(x) approximately= 1 GeV are enhanced and could at least partly explain the ΔI=1/2 rule. Thus a previous calculation within the bag model is confirmed. The present caluculation is performed wihtin an effective chiral theory with pions and kaons coupled to quarks. It has been found that low momentum left-left loop contributions are important, while left-right contributions can be neglected

    In American football, pass interference calls can be difficult to make, especially when the timing of contact between players is ambiguous. American football history contains many examples of controversial pass interference decisions, often with fans, players, and officials interpreting the same event differently. The current study sought to evaluate the influence of experience with concepts important for officiating decisions in American football on the probability (i.e., response criteria) of pass interference calls. We further investigated the extent to which such experience modulates perceptual biases that might influence the interpretation of such events. We hypothesized that observers with less experience with the American football concepts important for pass interference would make progressively more pass interference calls than more experienced observers, even when given an explicit description of the necessary criteria for a pass interference call. In a go/no-go experiment using photographs from American football games, three groups of participants with different levels of experience with American football (Football Naïve, Football Player, and Football Official) made pass interference calls for pictures depicting left-moving and right-moving events. More experience was associated with progressively and significantly fewer pass interference calls [F(2,48) = 10.4, p Football Naïve participants making the most pass interference calls, and Football Officials the least. In addition, our data replicated a prior finding of spatial biases for interpreting left-moving images more harshly than identical right-moving images, but only in Football Players. These data suggest that experience with the concepts important for making a decision may influence the rate of decision-making, and may also play a role in susceptibility to spatial biases.

    The energy turnaround is only making slow progress in the traffic sector. Biofuels, the most important alternative energy resource for traffic applications, have come under criticism, and their growth has stalled in recent years. Two questions present themselves in this situation: Where do biofuels stand today? And what can they contribute in future to the energy turnaround in the traffic sector? The present study on challenges and potentials associated with the use of biofuels in the traffic sector investigates the direction of current developments.

  6. Affective Biases and Heuristics in Decision Making : Emotion regulation as a factor for decision making competence

    2013-01-01

    Stanovich and West (2008) explored if measures of cognitive ability ignored some important aspects of thinking itself, namely that cognitive ability alone is not enough to generally prevent biased thinking. In this thesis a series of decision making (DM) tasks is tested to see if emotion regulation (ER) is a factor for the decision process and therefore should be a measured in decision making competence. A set of DM tasks was compiled involving both affective and cognitive dimensions. 400 par...

    The conservation of biodiversity is an important issue world wide and in Australia the maintenance of native biodiversity on farms makes an important contribution to overall conservation objectives. This paper seeks to explain Australian farmers' rationale for maintaining biodiversity on their farms for personal as opposed to business reasons by developing a decision-systems theory from in-depth interviews. This difference has implications for policy development. The decision-systems theory is divided into two main sections. The first section contains five parts. (1) A hierarchy of motivation stories, (2) the concept of suitability and availability of opportunities, (3) a hierarchy of three decision-systems, (4) the concept of personal career paths, (5) the concept of Lenses. The second section contains one part, a policy classification system called 'boxes of influence' that suggests how policy developers can use the information in the first section to develop new biodiversity conservation policy. The paper suggests that decision-systems theory could be used to shed new light on current trends in agriculture and become an important investigative tool for policy development concerning the conservation of biodiversity on farms.

    Fluid intelligence decreases with age, yet evidence about age declines in decision-making quality is mixed: Depending on the study, older adults make worse, equally good, or even better decisions than younger adults. We propose a potential explanation for this puzzle, namely that age differences in decision performance result from the interplay between two sets of cognitive capabilities that impact decision making, one in which older adults fare worse (i.e., fluid intelligence) and one in which they fare better (i.e., crystallized intelligence). Specifically, we hypothesized that older adults' higher levels of crystallized intelligence can provide an alternate pathway to good decisions when the fluid intelligence pathway declines. The performance of older adults relative to younger adults therefore depends on the relative importance of each type of intelligence for the decision at hand. We tested this complementary capabilities hypothesis in a broad sample of younger and older adults, collecting a battery of standard cognitive measures and measures of economically important decision-making "traits"--including temporal discounting, loss aversion, financial literacy, and debt literacy. We found that older participants performed as well as or better than younger participants on these four decision-making measures. Structural equation modeling verified our hypothesis: Older participants' greater crystallized intelligence offset their lower levels of fluid intelligence for temporal discounting, financial literacy, and debt literacy, but not for loss aversion. These results have important implications for public policy and for the design of effective decision environments for older adults.

    Full Text Available The purpose of this study was to investigate the linguistic forms, which commonly constitute meanings in the digital environment. The data were sampled from 200 Bachelor of Science (BS students (who had Urdu as their primary language of communication and English as one of the academic languages or the most prestigious second language of five universities situated in Lahore, Pakistan. The procedure for analysis was conceived within much related theoretical work on text analysis. The study reveals that cyber-language is organized through patterns of use, which can be broadly classified into minimal linguistic forms constituting a meaning-making resource. In addition, the expression of syntactic mood, and discourse roles the participants technically assume tend to contribute to the theory of meaning in the digital environment. It is hoped that the study would make some contribution to the growing literature on multilingual computer-mediated communication (CMC.

    Full Text Available It is not known whether patients with juvenile myoclonic epilepsy (JME differ from healthy people in decision making under risk, i.e., when the decision-making context offers explicit information about options, probabilities, and consequences already from the beginning. In this study, we adopted the Game of Dice Task-Double to investigate decision making under risk in a group of 36 patients with JME (mean age 25.25/SD 5.29 years and a group of 38 healthy controls (mean age 26.03/SD 4.84 years. Participants also underwent a comprehensive neuropsychological assessment focused on frontal executive functions. Significant group differences were found in tests of psychomotor speed and divided attention, with the patients scoring lower than the controls. Importantly, patients made risky decisions more frequently than controls. In the patient group, poor decision making was associated with poor executive control, poor response inhibition, and a short interval since the last seizure episode. Executive control and response inhibition could predict 42% of variance in the frequency of risky decisions. This study indicates that patients with JME with poorer executive functions are more likely to make risky decisions than healthy controls. Decision making under risk is of major importance in every-day life, especially with regard to treatment decisions and adherence to long-term medical therapy. Since even a single disadvantageous decision may have long-lasting consequences, this finding is of high relevance.

  13. Environmental Decision Making and Information Technology: Issues Assessment

    Barg, S.; Fletcher, T.; Mechling, J.; Tonn, B.; Turner, R.

    1999-05-01

    This report presents a summary of the Information Technology and Environmental Decision Making Workshop that was held at Harvard University, October 1-3, 1998. Over sixty participants from across the US took part in discussions that focused on the current practice of using information technology to support environmental decision making and on future considerations of information technology development, information policies, and data quality issues in this area. Current practice is focusing on geographic information systems and visualization tools, Internet applications, and data warehousing. In addition, numerous organizations are developing environmental enterprise systems to integrate environmental information resources. Plaguing these efforts are issues of data quality (and public trust), system design, and organizational change. In the future, much effort needs to focus on building community-based environmental decision-making systems and processes, which will be a challenge given that exactly what needs to be developed is largely unknown and that environmental decision making in this arena has been characterized by a high level of conflict. Experimentation and evaluation are needed to contribute to efficient and effective learning about how best to use information technology to improve environmental decision making.

  14. Building bridges between perceptual and economic decision-making: neural and computational mechanisms

    Full Text Available Investigation into the neural and computational bases of decision-making has proceeded in two parallel but distinct streams. Perceptual decision making (PDM is concerned with how observers detect, discriminate and categorise noisy sensory information. Economic decision making (EDM explores how options are selected on the basis of their reinforcement history. Traditionally, the subfields of PDM and EDM have employed different paradigms, proposed different mechanistic models, explored different brain regions, disagreed about whether decisions approach optimality. Nevertheless, we argue that there is a common framework for understanding decisions made in both domains, under which an agent has to combine sensory information (what is the stimulus with value information (what is it worth. We review computational models of the decision process typically used in PDM, based around the idea that decisions involve a serial integration of evidence, and assess their applicability to decisions between good and gambles. Subsequently, we consider the contribution of three key brain regions – the parietal cortex, the basal ganglia, and the orbitofrontal cortex – to perceptual and economic decision-making, with a focus on the mechanisms by which sensory and reward information are integrated during choice. We find that although the parietal cortex is often implicated in the integration of sensory evidence, there is evidence for its role in encoding the expected value of a decision. Similarly, although much research has emphasised the role of the striatum and orbitofrontal cortex in value-guided choices, they may play an important role in categorisation of perceptual information. In conclusion, we consider how findings from the two fields might be brought together, in order to move towards a general framework for understanding decision-making in humans and other primates.

    Social workers can make a significant contribution to military service members and their families, but first it is essential that the worldview, the mindset, and the historical perspective of life in the military are understood. Unless we understand how the unique characteristics of the military impact the service members and their families, we cannot work effectively with them. In addition, unless we understand their language, their structure, why they join, their commitment to the mission, and the role of honor and sacrifice in military service, we will not be able to adequately intervene and offer care to these families.
