    Many studies of mishaps show that human error is a factor in a significant majority of accidents. Trying to decide how to change human behavior to be safer is generally the biggest challenge of any safety program. However, understanding the human psyche is the first step to changing behavior. Many studies focus on the before and after of an accident, but what about the thoughts of a person in the commission of an unsafe act? This is a less understood area. Examining it reveals why it is not well comprehended. This paper attempts to examine a part of the thought process, with an eye to helping influence people to less hurtful actions.

    Full Text Available Based on the massive reading of data mining and association rules mining documents, this paper will start from compressing transactional database and propose the frequent complementary item storage structure of the transactional database. According to the previous analysis, this paper will also study the association rules mining algorithm based on the frequent complementary item storage structure of the transactional database. At last, this paper will apply this mining algorithm in the test results analysis module of team psychological health assessment system, and will extract the relationship between each psychological impact factor, so as to provide certain guidance for psychologists in their mental illness treatment.

    1992-01-01

    The Extra-Vehicular Activity Control System (EVACS) Simulation with Nested Transactions, a recent effort of the MISSION Kernel Team, is documented. The EVACS simulation is a simulation of some aspects of the Extra-Vehicular Activity Control System, in particular, just the selection of communication frequencies. The simulation is a tool to explore mission and safety critical (MASC) applications. For the purpose of this effort, its current definition is quite narrow serving only as a starting point for prototyping purposes. (Note that EVACS itself has been supplanted in a larger scenario of a lunar outpost with astronauts and a lunar rover). The frequency selection scenario was modified to embed its processing in nested transactions. Again as a first step, only two aspects of transaction support were implemented in this prototype: architecture and state recovery. Issues of concurrency and distribution are yet to be addressed.

  5. Psychological aspects of food safety risk perception

    DEFF Research Database (Denmark)

    Scholderer, Joachim

    Most consumers are not microbiologists and spend little time worrying about food safety. Evolution and civilisation have provided us with abilities to avoid the more serious risks, and in practice we tend to use these abilities quite well. However, there are certain conditions under which...... problematic food safety behaviours are likely to occur. The presentation will begin with an overview of the relevant psychological mechanisms that regulate approach and avoidance behaviour with respect to potentially hazardous foods. Learned representations of familiarity and reward value act as safety......: pleasure is tied to approach, surprise to orientation, disgust to avoidance. These mechanisms operate permanently and in an almost automatic manner. Problematic food safety behaviours often result when (a) easily detectable cues for spoilage or contamination do not exist, (b) when the diagnosticity...

  6. The application of the psychological contract to workplace safety.

    2006-01-01

    Psychological contracts of safety are conceptualized as the beliefs of individuals about reciprocal safety obligations inferred from implicit or explicit promises. Although the literature on psychological contracts is growing, the existence of psychological contracts in relation to safety has not been established. The research sought to identify psychological contracts in the conversations of employees about safety, by demonstrating reciprocity in relation to employer and employee safety obligations. The identified safety obligations were used to develop a measure of psychological contracts of safety. The participants were 131 employees attending safety training sessions in retail and manufacturing organizations. Non-participant observation was used to collect the data during safety training sessions. Content analysis was used to analyze the data. Categories for coding were established through identification of language markers that demonstrated contingencies or other implied obligations. Direct evidence of reciprocity between employer safety obligations and employee safety obligations was found in statements from the participants demonstrating psychological contracts. A comprehensive list of perceived employer and employee safety obligations was compiled and developed into a measure of psychological contracts of safety. A small sample of 33 safety personnel was used to validate the safety obligations. CONCLUSIONS AND IMPACT ON INDUSTRY: Implications of these findings for safety and psychological contract research are discussed.

  7. Risk, rationality, and community: Psychology, ethnography, and transactions in the risk management process

    Communities at risk are confronted by an increasingly complex array of opportunities and need for involvement in decisions affecting them. Policy analysis often demands from researchers insights into the complicated process of how best to account for community involvement in decision making. Often, this requires additional understanding of how decisions are made by community members. Researchers trying to capture the important features of decision making will necessarily make assumptions regarding the rationality underlying the decision process. Two implicit and often incompatible sets of research assumptions about decision processes have emerged: outcome rationality and process rationality. Using outcome rationality, the principal goal of risk research often is to predict how people will react to risk regardless of what they say they would do. Using process rationality, the research goal is to determine how people perceive the risks to which they are exposed and how perceptions actually influence responses. The former approach is associated with research in risk communication, conducted by economists and cognitive psychologists; the latter approach is associated with the field of risk negotiation and acceptance, conducted by anthropologists, some sociologists, and planners. This article describes (1) the difference between the assumptions behind outcome and process rationality regarding decision making and the problems resulting from these differences; (2) the promise and limitations of both sets of assumptions; (3) the potential contributions from cognitive psychology, cognitive ethnography, and the theory of transaction costs in reconciling the differences in assumptions and making them more complementary; and (4) the implications of such complementarity.

    In psychologically safe workplaces, employees feel comfortable taking interpersonal risks, such as pointing out errors. Previous research suggested that psychologically safe climate optimizes organizational outcomes. We evaluated psychological safety levels in Veterans Health Administration (VHA) hospitals and assessed their relationship to employee willingness of reporting medical errors. We conducted an ANOVA on psychological safety scores from a VHA employees census survey (n = 185,879), assessing variability of means across racial and supervisory levels. We examined organizational climate assessment interviews (n = 374) evaluating how many employees asserted willingness to report errors (or not) and their stated reasons. Finally, based on survey data, we identified 2 (psychologically safe versus unsafe) hospitals and compared their number of employees who would be willing/unwilling to report an error. Psychological safety increased with supervisory level (P report an error; retaliation fear was the most commonly mentioned deterrent. Furthermore, employees at the psychologically unsafe hospital (71% would report, 13% would not) were less willing to report an error than at the psychologically safe hospital (91% would, 0% would not). A substantial minority would not report an error and were willing to admit so in a private interview setting. Their stated reasons as well as higher psychological safety means for supervisory employees both suggest power as an important determinant. Intentions to report were associated with psychological safety, strongly suggesting this climate aspect as instrumental to improving patient safety and reducing costs.

    Forgiveness, as an intentional denial of your right of anger and aversion from a harmful deed, is related to many psychological processes of human which results in more psychological safety for people. The present study aimed to predict the psychological safety of nurses through different dimensions of forgiveness skill. This correlational study was conducted on 170 nurses working in Kerman hospitals during 2016-2017 who were selected based on convenience random sampling. Edmondson psychological safety and Thompson Heartland forgiveness scale were used for data collection. Data were analyzed through Pearson correlation coefficient and multiple regression model. TThe results indicated that psychological safety has a significant relationship with self-forgiveness ( p = 0.0001) and other-forgiveness ( p = 0.04). Further, only self-forgiveness could significantly predict 0.07 of psychological safety variance ( p = 0.003). Self-forgiveness skill can improve the nurses' psychological safety and reduce the harms caused by job pressures by reinforcing positive psychological factors. It is recommended to teach forgiveness skill through holding in-service classes to staff and study the relationship between psychological safety with other social life skills among nurses.

    Full Text Available Main causes of accident is due to driver itself that is influenced by their bad attitude while driving. Human attitude is closely related to the human psychology. Apart from that, spiritual aspect also influence human attitude. Hence, this study carried out to improve driver safety using a new approach through psychology and spiritual factors. Objectives of this study are to identify then analyze factors of psychological and spiritual that contribute towards safety driving. A self-administered questionnaire were distributed among 256 respondents from various type of background. An analysis descriptive statistics show demographic and experience of respondents. Chi-square analysis showed only education level and traffic summon are significant to safety driving. Furthermore, correlation analysis shows psychological factors has strong linear relationship on attitude of drivers towards safety driving while spiritual factor, the perception of the spiritual and practices, both have a strong relationship to safety driving. Regression analysis demonstrates boths psychological and spiritual factors have strong evidence and significant relationship with safety driving. Thus, it can be identified that spiritual psychological factors encourage drivers to drive more safely and reduce road accidents. Therefore, this study propose useful guidelines to related agencies in order to enhance safety among drivers to be able drive safely on the road.

    The purpose of this paper is to explore employee perceptions of communication in psychologically safe and unsafe clinical care environments. Clinical providers at the USA Veterans Health Administration were interviewed as part of planning organizational interventions. They discussed strengths, weaknesses, and desired changes in their workplaces. A subset of respondents also discussed workplace psychological safety (i.e. employee perceptions of being able to speak up or report errors without retaliation or ostracism--Edmondson, 1999). Two trained coders analysed the interview data using a grounded theory-based method. They excerpted passages that discussed job-related communication and summarized specific themes. Subsequent analyses compared frequencies of themes across workgroups defined as having psychologically safe vs unsafe climate based upon an independently administered employee survey. Perceptions of work-related communication differed across clinical provider groups with high vs low psychological safety. The differences in frequencies of communication-related themes across the compared groups matched the expected pattern of problem-laden communication characterizing psychologically unsafe workplaces. Previous research implied the existence of a connection between communication and psychological safety whereas this study offers substantive evidence of it. The paper summarized the differences in perceptions of communication in high vs low psychological safety environments drawing from qualitative data that reflected clinical providers' direct experience on the job. The paper also illustrated the conclusions with multiple specific examples. The findings are informative to health care providers seeking to improve communication within care delivery teams.

    The goals of this study were twofold: (1) to confirm a relationship between employee perceptions of psychological safety climate and safety behavior for a sample of workers in the rail industry and (2) to explore the relative strengths of relationships between specific facets of safety climate and safety behavior. Non-management rail maintenance workers employed by a large North American railroad completed a survey (n=421) regarding workplace safety perceptions and behaviors. Three facets of safety climate (management safety, coworker safety, and work-safety tension) were assessed as relating to individual workers' reported safety behavior. All three facets were significantly associated with safety behavior. Dominance analysis was used to assess the relative importance of each facet as related to the outcome, and work-safety tension evidenced the strongest relationship with safety behavior.

    Full Text Available The interest of psychologists in the study of safety in the educational environment and its psychological characteristics is increasing. The aim of this study was to select, substantiate, and disclose the psychological factors in the educational environment that influence the psychological well-being of pupils. There were three stages in our research: clarifying the level of psychological safety in the schools in the study; revealing the consistency of the teachers’ and the students’ evaluations of the level of psychological safety in those schools; determining the nature of the influence of the psychological safety of the educational environment on the psychological well-being of the students. The study involved 172 teachers and 876 students in Moscow and St. Petersburg schools. Psychological safety is a condition of educational environments that are free from psychological violence in the interactions of the people in them; psychological safety contributes to the satisfaction of the needs for personal trust and communication, creates for the participants a sense of belonging (the referential importance of the environment, and contributes to their mental health. The empirical study revealed that (1 the level of the psychological safety of the educational environment in the evaluations of the teachers was higher and had more expressed differentiation than did the level in the students’ evaluations; (2 the psychological well-being of the students was closely correlated with the level of psychological safety for the teachers; (3 such components of the well-being of the students as emotional comfort, self-confidence, a higher level of cognitive activity were developed in those schools with high levels of psychological safety for the teachers. The results can be useful in educational psychology and environmental psychology as well as when creating technologies to support the safety of school environments and of the people in them, including

    This study investigated (1) reciprocal links among parental psychological control, peer rejection, and adolescent externalizing (aggressive and rule-breaking behaviour), and (2) the moderating effect of an adolescent genetic factor (biologically informed polygenic score for dopamine signalling). Three-year longitudinal data from 1,116 adolescents (51% boys; M age = 13.79) and their parents included psychological measures (adolescent-reported psychological control, peer-reported rejection, and parent-reported aggressive and rule-breaking behaviour). Cross-lagged analyses showed bidirectional effects between psychological control and both aggressive and rule-breaking behaviour and a unidirectional effect of peer rejection on both forms of problem behaviour over time. Multigroup structural equation modelling revealed genetic moderation only for rule-breaking behaviour: for adolescents with intermediate levels of dopamine signalling significant environmental effects were present, whereas adolescent effects of rule-breaking behaviour on psychological control were significant for adolescents with both intermediate and high profiles and effects on peer rejection only for adolescents with high dopamine profiles. Statement of contribution What is already known on this subject? Parental psychological control is related to adolescent externalizing problems. Experiencing peer rejection reinforces aggressive and rule-breaking behaviour. Single-gene studies show that dopaminergic genes influence externalizing problems directly or in interaction with the environment. What does this study add? Parental psychological control and adolescent aggressive and rule-breaking behaviour exacerbate one another longitudinally. Longitudinal associations between peer rejection and both subtypes of externalizing behaviour are unidirectional. With a polygenic approach, dopaminergic moderation is present for rule-breaking behaviour only. © 2017 The British Psychological Society.

    Oedewald, P.; Reiman, T.

    2007-03-15

    This book deals with organizations that operate in high hazard industries, such as the nuclear power, aviation, oil and chemical industry organizations. The society puts a great strain on these organizations to rigorously manage the risks inherent in the technology they use and the products they produce. In this book, an organizational psychology view is taken to analyse what are the typical challenges of daily work in these environments. The analysis is based on a literature review about human and organizational factors in safety critical industries, and on the interviews of Finnish safety experts and safety managers from four different companies. In addition to this, personnel interviews conducted in the Finnish nuclear power plants are utilised. The authors come up with eight themes that seem to be common organizational challenges cross the industries. These include e.g. how does the personnel understand the risks and what is the right level for rules and procedures to guide the work activities. The primary aim of this book is to contribute to the nuclear safety research and safety management discussion. However, the book is equally suitable for risk management, organizational development and human resources management specialists in different industries. The purpose is to encourage readers to consider how the human and organizational factors are seen in the field they work in. (orig.)

    2007-08-01

    Full Text Available The paper examines a relative predictive value of some stable individual attributes and the processes of cognitive appraisals and coping with stress in accounting for specific components of anxiety state measures. Self-report instruments for the measurement of selected psychological constructs, i.e. perceived incompetence, externality, stress intensity and duration, situation-specific coping strategies, and the two anxiety state components, were taken in a sample of 449 male military basics trainees, ranging in age from 18-27. Hierarchical multiple regression analyses showed that the set of predictors employed could account for statistically, as well as theoretically and practically a significant part of variance in cognitive anxiety component (45,5%, and in visceral-emotional component (32,2% of the anxiety state. The extent of anxiety reactions assessed by both scales could primarily be explained by general perception of personal incompetence, as a relatively stable dimension of general self-concept. Of the ways of coping examined, reinterpretation of stressful events was the only strategy contributing to low level, whereas passivization, wishful thinking, and seeking social support contributed to higher levels of anxiety measured by both scales. The results give partial support to the basic hypotheses on the mediating role of coping in the relationships among particular components of the stress and coping models.

On the basis of analysis of ideas about psychological safety in sports and their representation in printed or verbal form the necessity of overcoming the fragmentation and lack of system is substantiated. The authors state that one and the same sports situation can constructively or destructively affect the psychological safety of direct or indirect participants of sports events. In this context, it is important to create the psycholinguistic basis of experimental research of psychological safety in sports. Great attention is paid to systematization of the content of the concept “psychological safety in sports”. The created models of words and expressions that convey ideas about this phenomenon are of particular value. In the structure of the concept the dominant meanings, expressed in the nucleus, and additional meanings, related to the periphery of the concept are distinguished.Purpose: to explore the ideas of psychological safety in sports and their representation in printed or verbal form; to determine ways of overcoming the conceptual psycholinguistic problems in the process of experimental research of psychological safety in sports; to create the model of words and expressions which are used to verbalize the concept “psychological safety in sports”.Methodology: theoretical analysis of psychological and linguistic literature, creation of the psycholinguistic basis of experimental research, modeling of the conceptual ideas of psychological safety in sports.Results: psycholinguistic basis of experimental research of psychological safety in sports, the model of content and structure of the corresponding concept.Practical implications: Pedagogical Psychology, Sports Psychology, Philology, Psycholinguistics.DOI: http://dx.doi.org/10.12731/2218-7405-2013-8-11

    Full Text Available There is a considerable decrease in psychological well-being among mothers raising children with special needs. Addressing the issues of providing psychological support for them is of particular importance for both researchers and practitioners. The paper presents a study aimed at exploring the dynamics of psychological safety in mothers raising children with special needs. 32 mothers whose children underwent a rehabilitation programme in a rehabilitation centre participated in the study. The key element of the psychological support programme developed for these mothers was a specific psychotherapeutic space combining hippotherapy with environmental, social and personal factors. Compared to the control group, the study participants’ parameters of psychological safety showed statistically significant positive dynamics. The results obtained contribute to studying factors of psychological well-being in mothers raising children with special needs and suggest an effective way of enhancing their sense of psychological safety.

    Safety climate research has reached a mature stage of development, with a number of meta-analyses demonstrating the link between safety climate and safety outcomes. More recently, there has been interest from systems theorists in integrating the concept of safety culture and to a lesser extent, safety climate into systems-based models of organizational safety. Such models represent a theoretical and practical development of the safety climate concept by positioning climate as part of a dynamic work system in which perceptions of safety act to constrain and shape employee behavior. We propose safety climate and safety culture constitute part of the enabling capitals through which organizations build safety capability. We discuss how organizations can deploy different configurations of enabling capital to exert control over work systems and maintain safe and productive performance. We outline 4 key strategies through which organizations to reconcile the system control problems of promotion versus prevention, and stability versus flexibility.

    The advent of multicore processors has renewed interest in the idea of incorporating transactions into the programming model used to write parallel programs.This approach, known as transactional memory, offers an alternative, and hopefully better, way to coordinate concurrent threads. The ACI(atomicity, consistency, isolation) properties of transactions provide a foundation to ensure that concurrent reads and writes of shared data do not produce inconsistent or incorrect results. At a higher level, a computation wrapped in a transaction executes atomically - either it completes successfullyand

    This study examines the indirect role of psychological safety in shaping the four cognitions of psychological empowerment (i.e., meaning, competence, self-determination, impact) through three social mechanisms: authentic interactions, spiritual development, and perceived organizational voice. Data were collected from 229 congregation members of a nondenominational church. Preliminary analyses reveal psychological safety is: (a) linked to all four empowerment cognitions, (b) associated with the three proximal social mechanisms, and (c) indirectly predicts three of the four empowerment cognitions through heightened level of authentic interactions, spiritual development, and perceived organizational voice. Moreover, extraversion moderated the relationship of psychological safety with authentic interactions which, in turn, strengthened the size of the indirect effect for the meaning subcomponent of empowerment. Overall, this study suggests empowerment research can draw upon the potential, but frequently untapped, benefits of cultivating a secure space to facilitate member motivation through sincerity, personal development, and perceived voice.

    Full Text Available During the production process, the instability of safety psychological elements of coal miners contributes to unsafe behaviors that may result in fatal accident. To search the dominant psychological elements, three types of unsafe psychology, comprising 18 unsafe psychological elements, are obtained by theoretical analysis and site survey. Then, an assessment model is established, and a matched questionnaire is applied to two large modern coal mines in Inner Mongolia Autonomous Region. Based on questionnaire survey results and analytic hierarchy process (AHP, assessment judgment matrixes are constructed, effect weight is calculated, and consistency check is conducted. The analysis results show that safety psychology elements of defective type are the dominant elements that trigger unsafe behaviors of coal miners.

    Full Text Available The safety of construction workers is always a major concern at construction sites as the construction industry is inherently dangerous with many factors influencing worker safety. Several studies concluded that psychological factors such as workload, organizational relationships, mental stress, job security, and job satisfaction have significant effects on workers’ safety. However, research on psychological factors that are characteristic of different age groups have been limited. The aim of this study was to examine the impact of psychological factors on the perception of worker safety for two different age groups. After an extensive literature review, different psychological factors were identified, and a hypothetical research model was developed based on psychological factors that could affect workers’ perception of safety. A survey instrument was developed, and data were collected from seven different construction sites in Pakistan. Structural equation modeling (SEM was employed to test the hypothetical model for both age groups. The results revealed that workload and job satisfaction are significantly dominant factors on workers’ perception of safety in older workers, whereas organizational relationships, mental stress, and job security are dominant factors for younger workers at construction sites.

    Despite efforts to prepare a psychologically safe environment, simulation participants are occasionally psychologically distressed. Instructing simulation educators about participant psychological risks and having a participant psychological distress action plan available to simulation educators may assist them as they seek to keep all participants psychologically safe. A Simulation Participant Psychological Safety Algorithm was designed to aid simulation educators as they debrief simulation participants perceived to have psychological distress and categorize these events as mild (level 1), moderate (level 2), or severe (level 3). A prebrief dedicated to creating a psychologically safe learning environment was held constant. The algorithm was used for 18 months in an active pediatric simulation program. Data collected included level of participant psychological distress as perceived and categorized by the simulation team using the algorithm, type of simulation that participants went through, who debriefed, and timing of when psychological distress was perceived to occur during the simulation session. The Kruskal-Wallis test was used to evaluate the relationship between events and simulation type, events and simulation educator team who debriefed, and timing of event during the simulation session. A total of 3900 participants went through 399 simulation sessions between August 1, 2014, and January 26, 2016. Thirty-four (simulation participants from 27 sessions (7%) were perceived to have an event. One participant was perceived to have a severe (level 3) psychological distress event. Events occurred more commonly in high-intensity simulations, with novice learners and with specific educator teams. Simulation type and simulation educator team were associated with occurrence of events (P simulation personnel using the Simulation Participant Psychological Safety Algorithm is rare, with mild and moderate events being more common. The algorithm was used to teach

    The construction industry has hit a plateau in terms of safety performance. Safety climate is regarded as a leading indicator of safety performance; however, relatively little safety climate research has been done in the Canadian construction industry. Safety climate may be geographically sensitive, thus it is necessary to examine how the construct of safety climate is defined and used to improve safety performance in different regions. On the other hand, more and more attention has been paid to job related stress in the construction industry. Previous research proposed that individual resilience may be associated with a better safety performance and may help employees manage stress. Unfortunately, few empirical research studies have examined this hypothesis. This paper aims to examine the role of safety climate and individual resilience in safety performance and job stress in the Canadian construction industry. The research was based on 837 surveys collected in Ontario between June 2015 and June 2016. Structural equation modeling (SEM) techniques were used to explore the impact of individual resilience and safety climate on physical safety outcomes and on psychological stress among construction workers. The results show that safety climate not only affected construction workers' safety performance but also indirectly affected their psychological stress. In addition, it was found that individual resilience had a direct negative impact on psychological stress but had no impact on physical safety outcomes. These findings highlight the roles of both organizational and individual factors in individual safety performance and in psychological well-being. Construction organizations need to not only monitor employees' safety performance, but also to assess their employees' psychological well-being. Promoting a positive safety climate together with developing training programs focusing on improving employees' psychological health - especially post-trauma psychological

  5. Trust in Supervisor and Job Engagement: Mediating Effects of Psychological Safety and Felt Obligation.

    In the social context of job engagement, the role of trust in supervisor in predicting engagement of employees has received attention in research. Very limited research, however, has investigated the mechanisms mediating this dynamic relationship. To address this important gap in knowledge, the aim of this study was to examine psychological safety and felt obligation as two psychological mechanisms mediating the effect of trust in supervisor on job engagement. Drawing from job engagement and social exchange theories, the mediating roles of psychological safety and felt obligation in the trust-engagement relationship were empirically investigated in the Malaysian context. Using self-report questionnaires, data were collected from 337 nurses employed in a public hospital located near Kuala Lumpur, Malaysia. Results fully supported the proposed serial multiple mediator model. Trust in supervisor was indirectly related to job engagement via psychological safety followed by felt obligation. This study provides empirical evidence that trust in supervisor makes employees feel psychologically safe to employ and express their selves in their job roles. This satisfaction of the psychological safety need is interpreted by employees as an important socioemotional benefit that, in turn, makes them feel obligated to pay back to their organization through their enhanced level of job engagement. Implications for theory and practice were discussed.

    Objective To examine individual, situational and organisational aspects that influence psychological impact and recovery of a patient safety incident on physicians, nurses and midwives. Design Cross-sectional, retrospective surveys of physicians, midwives and nurses. Setting 33 Belgian hospitals. Participants 913 clinicians (186 physicians, 682 nurses, 45 midwives) involved in a patient safety incident. Main outcome measures The Impact of Event Scale was used to retrospectively measure psychological impact of the safety incident at the time of the event and compare it with psychological impact at the time of the survey. Results Individual, situational as well as organisational aspects influenced psychological impact and recovery of a patient safety incident. Psychological impact is higher when the degree of harm for the patient is more severe, when healthcare professionals feel responsible for the incident and among female healthcare professionals. Impact of degree of harm differed across clinicians. Psychological impact is lower among more optimistic professionals. Overall, impact decreased significantly over time. This effect was more pronounced for women and for those who feel responsible for the incident. The longer ago the incident took place, the stronger impact had decreased. Also, higher psychological impact is related with the use of a more active coping and planning coping strategy, and is unrelated to support seeking coping strategies. Rendered support and a support culture reduce psychological impact, whereas a blame culture increases psychological impact. No associations were found with job experience and resilience of the health professional, the presence of a second victim support team or guideline and working in a learning culture. Conclusions Healthcare organisations should anticipate on providing their staff appropriate and timely support structures that are tailored to the healthcare professional involved in the incident and to the specific

    The aim of this study was to examine the impacts of nurses' psychological capital and managerial support, plus specific safety interventions (managerial safety priorities, safety training satisfaction), on nurses' in-role safety performance. Most hospitals in industrialized countries have adopted selective (often the least costly) aspects of safety, usually related to safety policies. However, patient safety remains a challenge in many countries. Research shows that training can be used to upskill employees in psychological capital, with statistically significant organizational and employee benefits, but this area is under-researched in nursing. Data were collected using a survey-based, self-report strategy. The emerging patterns of data were then compared with the findings of previous research. Quantitative survey data were collected during 2014 from 242 nurses working in six Australian hospitals. Two models were tested and analysed using covariance-based Structural Equation Modelling. Psychological capital and safety training satisfaction were important predictors of nurses' in-role safety performance and as predictors of nurses' perceptions of whether management implements what it espouses about safety ('managerial safety priorities'). Managerial support accounted for just under a third of psychological capital and together, psychological capital and managerial support, plus satisfaction with safety training, were important to nurses' perceptions of in-role safety performance. Organizations are likely to benefit from upskilling nurses and their managers to increase nurses' psychological capital and managerial support, which then will enhance nurses' satisfaction with training and in-role safety performance perceptions. © 2016 John Wiley & Sons Ltd.

  8. Communicating Transactions

    de Vries, Edsko; Koutavas, Vasileios; Hennessy, Matthew

    We propose a novel language construct called communicating transactions, obtained by dropping the isolation requirement from classical transactions, which can be used to model automatic error recovery in distributed systems. We extend CCS with this construct and give a simple semantics for the extended calculus, called TransCCS. We develop a behavioural theory which is sound and complete with respect to the may-testing preorder, and use it to prove interesting laws and reason compositionally about example systems. Finally, we prove that communicating transactions do not increase the observational power of processes; thus CCS equivalences are preserved in the extended language.

    Effective communication is a requirement in the teamwork necessary for improved coordination to deliver patient-centered, value-based cancer care. Communication is particularly important when care providers are geographically distributed or work across organizations. We review organizational and teams research on communication to highlight psychological safety as a key determinant of high-quality communication within teams. We first present the concept of psychological safety, findings about its communication effects for teamwork, and factors that affect it. We focus on five factors applicable to cancer care delivery: familiarity, clinical hierarchy-related status differences, geographic dispersion, boundary spanning, and leader behavior. To illustrate how these factors facilitate or hinder psychologically safe communication and teamwork in cancer care, we review the case of a patient as she experiences the treatment-planning process for early-stage breast cancer in a community setting. Our analysis is summarized in a key principle: Teamwork in cancer care requires high-quality communication, which depends on psychological safety for all team members, clinicians and patients alike. We conclude with a discussion of the implications of psychological safety in clinical care and suggestions for future research.

    2017-01-11

    We aimed to investigate the interactive effects of perceived neighborhood safety and social cohesion on the psychological health of older adults with and without functional impairments. This cross-sectional study included 13,897 community-dwelling older adults (aged 65 years and older) from the 2011-2012 California Health Interview Survey (CHIS). Hypotheses were tested using weighted moderated ordinary least squared regression analysis. Perceived neighborhood safety was significantly associated with psychological health regardless of respondents' physical functioning, although the effect was greater among older adults with functional limitations. Perceived social cohesion, however, was only significantly related to psychological health among those with functional limitations. Among physically impaired respondents, social cohesion buffered the ill-effect of an unsafe neighborhood on psychological health. Findings suggest that efforts to promote perceived neighborhood safety and social cohesion are essential to the well-being of older adults. Special attention should be paid to older adults with functional limitations, who appear to be more vulnerable to the negative effects of neighborhood environments. © The Author 2017.

    Although the reporting of adverse events is a necessary first step in identifying and addressing lapses in patient safety, such events are under-reported, especially by frontline providers such as resident physicians. This study describes and tests relationships between power distance and leader inclusiveness on psychological safety and the willingness of residents to report adverse events. A total of 106 resident physicians from the departments of neurosurgery, orthopaedic surgery, emergency medicine, otolaryngology, neurology, obstetrics and gynaecology, paediatrics and general surgery in a mid-Atlantic teaching hospital were asked to complete a survey on psychological safety, perceived power distance, leader inclusiveness and intention to report adverse events. Perceived power distance (β = -0.26, standard error [SE] 0.06, 95% confidence interval [CI] -0.37 to 0.15; p culture external to the individual, it should be viewed as an organisational as much as a personal function. Supervisors and other leaders in health care should ensure that policies, procedures and leadership practices build psychological safety and minimise power distance between low- and high-status members in order to support greater reporting of adverse events. © 2016 John Wiley & Sons Ltd.

    In this study, we identify leader humility, characterized by being open to admitting one's limitations, shortcomings, and mistakes, and showing appreciation and giving credit to followers, as a critical leader characteristic relevant for team creativity. Integrating the literatures on creativity and leadership, we explore the relationship between leader humility and team creativity, treating team psychological safety and team information sharing as mediators. Further, we hypothesize and examine team power distance as a moderator of the relationship. We tested our hypotheses using data gathered from 72 work teams and 354 individual members from 11 information and technology firms in China using a multiple-source, time-lagged research design. We found that the positive relationship between leader humility and team information sharing was significant and positive only within teams with a low power distance value. In addition, leader humility was negatively related to team psychological safety in teams with a high power distance value, whereas the relationship was positive yet nonsignificant in teams with low power distance. Furthermore, team information sharing and psychological safety were both significantly related to team creativity. We discuss theoretical and practical implications for leadership and work teams.

    Full Text Available The paper describes trade operations in lea­sin­g companies as specific businesses enabling acquisition of possession by legal and physical persons by gradual repayments of the purchase price. On a diagram it shows the complexity of business relations between the main participants of a lea­sin­g transaction, which are production companies, lea­sin­g companies and those interested in the subject of lea­sin­g. To capture the complexity of relations, there are also included all other participants. Their function in a lea­sin­g transaction starts only at the moment, when the leaseholders are not able to pay their liabilities to which they agreed in the innominate contract. Paper clarifies the term “lea­sin­g with zero mark-up”. With the help of calculation it describes the basis of a lea­sin­g transaction, where significantly participates also the production company, insurance company and commercial bank. All these subjects have certain benefits from a realized transaction. These are enabled by their close business relationships with the lea­sin­g company, which is sufficiently clear from the diagram and it is also substantiated by calculations. Paper includes a definition of lea­sin­g operations, as well as a ma­the­ma­ti­cal model of lea­sin­g payments calculation for a car. A part of the paper is also dealing with a cession of a lea­sin­g contract in the person of a leaseholder as a specific case enforced by financial issues of the leaseholder. The paper elaborates alternatives of evaluating client’s bonding capacity with the help of financial indicators.

    2009-01-01

    This paper aims to provide researchers and practitioners with an overview of how organisation behaviour research (OBR) helps to understand and resolve patient safety problems in health care. The paper describes psychological, sociological and other social science theories and research which help to understand the causes of patient safety problems, how to implement change effectively and how to create an organisational culture of safety. Social science perspectives and organisational behaviour research are beginning to show why improvements in patient safety are slow, and how to make lasting and effective change. Social sciences and OBR have already helped make healthcare safer, but could make a greater contribution. Progress could be faster with greater awareness of the findings of this research and understanding of social science research paradigms. Better implementation and safer care could result from providing implementers and decision makers with more knowledge and access to social science research. More useful social science research could be developed by research funders and proposal reviewers gaining a greater understanding of social science methods and potential, and by including this research in a field made up largely of traditional experimental medical research methods. This paper provides an overview of the scientific and practical contributions of social sciences to patient safety and shows where future studies could assist understanding of current challenges and speed implementation of change.

    Full Text Available Orientation: Transformational team leadership is an important variable that influences team members’ perception of the team as psychologically safe enough to engage in learning behaviours.Research purpose: The study was aimed at investigating the relationship between psychological safety and learning behaviour in teams, as well as the moderating role of transformational team leadership in this relationship.Motivation for the study: For a team to be effective, adaptive and innovative and engage in learning behaviours, the transformational team leader must set the right climate in the team, where he or she welcomes the team members’ opinions, questions and feedback at no risk to their image. An understanding of this will be important in team leader selection and training.Research design, approach and method: Using a cross-sectional survey design, 57 work teams comprising 456 respondents in teams of 7–9 members were purposively sampled from five financial institutions in Accra, Ghana. Hierarchical regression and moderation analyses were run on the data at the team level.Main findings: Results indicated a positive relationship between team psychological safety and team learning behaviour, with transformational team leadership moderating this relationship.Practical/managerial implication: Transformational team leadership is important in creating a climate of psychological safety that will enable team members to engage in learning behaviours.Contribution/value-add: The study provided theoretical and empirical evidence that, in organisational contexts, transformational team leadership is an important variable that can facilitate psychological safety and learning behaviour in teams.

    Mentoring continues to build momentum among startups and established enterprises due to its positive impact on individuals and organizations. Unlike previous studies, this research focuses on mentoring higher level leadership, such as the CEO, and demonstrates its unique relationship to organizational innovativeness. Our sample included 200 mentored executives and entrepreneurs who personally identify and exploit opportunities. Our findings confirm that mentoring top leaders positively relates to their perceived innovativeness of the organization and that the relationship is mediated by these leaders' perception of psychological safety within the organization. Our findings also confirm that the relationship is negatively moderated by these leaders' cognitive adaptability. The reliability and validity of the results have been proved by using confirmatory factor analysis and advanced regression analytics. As a result, this work demonstrates the value of mentoring top leadership and advocates the importance of establishing a psychologically safe environment to inspire not only top leadership to try new avenues but also for all those within the organization to speak up and speak out. Additionally, our findings encourage organizations to proactively and selectively prioritize mentoring among top leadership, taking into account their differing levels of cognitive adaptability. Finally, further research could focus on how to provide greater support for mentors of higher level leaders.

  6. Psychosocial safety climate as a lead indicator of workplace bullying and harassment, job resources, psychological health and employee engagement.

    2011-09-01

    Psychosocial safety climate (PSC) is defined as shared perceptions of organizational policies, practices and procedures for the protection of worker psychological health and safety, that stem largely from management practices. PSC theory extends the Job Demands-Resources (JD-R) framework and proposes that organizational level PSC determines work conditions and subsequently, psychological health problems and work engagement. Our sample was derived from the Australian Workplace Barometer project and comprised 30 organizations, and 220 employees. As expected, hierarchical linear modeling showed that organizational PSC was negatively associated with workplace bullying and harassment (demands) and in turn psychological health problems (health impairment path). PSC was also positively associated with work rewards (resources) and in turn work engagement (motivational path). Accordingly, we found that PSC triggered both the health impairment and motivational pathways, thus justifying extending the JD-R model in a multilevel way. Further we found that PSC, as an organization-based resource, moderated the positive relationship between bullying/harassment and psychological health problems, and the negative relationship between bullying/harassment and engagement. The findings provide evidence for a multilevel model of PSC as a lead indicator of workplace psychosocial hazards (high demands, low resources), psychological health and employee engagement, and as a potential moderator of psychosocial hazard effects. PSC is therefore an efficient target for primary and secondary intervention. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available The federal government standard defines educational objectives of education and development of such a person who can meet their needs, as well as the needs of society and the state. The standard combines individual, public and state needs. The new standard requires the teaching staff of the institution to create conditions for subjective well-being of trainees. Subjective well-being is regarded as the emotional state of the integral human satisfaction with various aspects of their life and life in general. An important condition for psychological well-being is a specially arranged educational environment in which the student is a significant part of it. Safety is an integral indicator of satisfaction, security, referential educational environment. To study this problem the security educational environment was monitored among schools. The total number of respondents amounted to 810 persons. The main purpose of the monitoring is to provide objective and reliable information about the security role of the educational environment in the formation of subjective well-being of students. The strongest link between security of the educational environment and the subjective wellbeing of students was revealed at schools that implemented pilot programs, innovative projects, in-depth studies of particular subjects. They were identified as protective factors of the educational environment.

  8. The mediating relationship of self-awareness on supervisor burnout and workgroup Civility & Psychological Safety: A multilevel path analysis

    2015-03-01

    Full Text Available The purpose of this study was to examine whether managerial self-awareness (defined as degree of agreement between self and subordinate ratings of leaders’ behaviors mediates the relationship between supervisor burnout and supervised workgroup climate. Using an HLM approach, supervisor emotional exhaustion, depersonalization and personal accomplishment exhibited significant indirect relationships with workplace Civility and Psychological Safety, via managerial self-awareness. No direct relationships between supervisor burnout and workgroup climate were found, suggesting that self-awareness may be an important mediator for individual characteristics of leaders previously thought to be non-significant. Additional post hoc comparisons indicated that workgroups with supervisors who over-rated their own performance behaviors reported the lowest levels of Civility and Psychological Safety compared to workgroups with supervisors who accurately rated or under-rated their own performance behaviors. However, supervisors that under-rated their own performance reported the highest levels of burnout, highlighting the importance of self-awareness (accurately rating oneself in relation to individual and group outcomes. The relationships between supervisor burnout, managerial self-awareness, and workgroup perceptions of Civility and Psychological Safety differed when considering the directionality of self-other rating agreement, with the negative impact of burnout at the supervisor level having a more direct impact on the workgroup level perceptions of Civility and Psychological Safety when the workgroup is managed by an under-rater, as opposed to an accurate- or over-rater. Practically, organizations should consider the role of managerial self-awareness in influencing subordinate performance and creating desirable work climates. Also, this study suggests the effects of burnout extend beyond the individual and have significant implications for the performance

    2009-09-01

    The antecedents and consequences of ethical leadership were examined in a study of 894 employees and their 222 immediate supervisors in a major financial institution in the United States. The leader personality traits of agreeableness and conscientiousness were positively related to direct reports' ratings of the leader's ethical leadership, whereas neuroticism was unrelated to these ratings. Ethical leadership influenced followers' voice behavior as rated by followers' immediate supervisors. This relationship was partially mediated by followers' perceptions of psychological safety. Implications for research on ethical leadership and means to enhance ethical behavior among leaders and nonleaders are discussed.

    This is a final report from a project funded by the U.S. Department of Energy to formulate and test a methodology for valuation of systems where transaction-based mechanisms coordinate the exchange of value between the system’s actors. Today, the principal commodity being exchanged is electrical energy, and such mechanisms are called transactive energy systems. The authors strove to lay a foundation for meaningful valuations of transactive systems in general, and transactive energy systems as a special case. The word valuation is used in many different ways. This report proposes a valuation methodology that is inclusive of many types of valuations. Many will be familiar with cost-benefit valuations, in which both costs and benefits are assessed to determine whether the assets are worth their cost. Another set of valuation methods attempt to optimize an outcome using available resources, as is the case with integrated resource planning. In the end, this report’s methodology was most influenced by and most resembles the integrated-resource-planning approach. Regardless, we wish to enforce the premise that all valuations are comparative and should clearly specify a baseline scenario. A long, annotated list of prior valuation studies and valuation methodologies that influenced this report has been appended to this report. Much research is being conducted today concerning transactive systems, but only a handful of transactive system mechanisms have been formulated and field tested. They are found to be quite diverse, and the documentation of the various mechanisms is uneven in breadth and quality. It is therefore not adequate to simply assert that a valuation scenario includes a transactive system; certain characteristics and qualities of the chosen transactive system mechanism must be defined and stated. The report lists and discusses most of the known transactive system mechanisms. It offers a set of questions that may be used to help specify important

    In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop air conditioners and heat pump units (RTUs) and the electric grid using applications or "agents" that reside on the platform, on the equipment, on a local building controller or in the Cloud. The transactional network project is a multi-lab effort with Oakridge National Laboratory (ORNL) and Lawrence Berkeley National Laboratory (LBNL) also contributing to the effort. PNNL coordinated the project and also was responsible for the development of the transactional network (TN) platform and three different applications associated with RTUs. This document describes two applications or "agents" in details, and also summarizes the platform. The TN platform details are described in another companion document.

    Psychological safety (PS) is the perception that it is safe to take interpersonal risks in the work environment. In teaching hospitals, PS may influence the clinical learning environment for trainees. We assessed whether resident physicians believe they are psychologically safe, and if PS is associated with how they rate satisfaction with their clinical learning experience. Data were extracted from the Learners' Perceptions Survey (LPS) of residents who rotated through a Department of Veterans Affairs health care facility for academic years 2011-2014. Predictors of PS and its association with resident satisfaction were adjusted to account for confounding and response rate biases using generalized linear models. The 13 044 respondents who completed the LPS (30% response rate) were comparable to nonpediatric, non-obstetrics-gynecology residents enrolled in US residency programs. Among respondents, 11 599 (89%) agreed that ". . . members of the clinical team of which I was part are able to bring up problems and tough issues." Residents were more likely to report PS if they were male, were in a less complex clinical facility, in an other medicine or psychiatry specialty, or cared for patients who were aged, had multiple illnesses, or had social supports. Nonpsychiatric residents felt safer when treating patients with no concurrent mental health diagnoses. PS was strongly associated with how residents rated their satisfaction across 4 domains of their clinical learning experience (P < .001). PS appears to be an important factor in resident satisfaction across 4 domains that evaluators of graduate medical education programs should consider when assessing clinical learning experiences.

    Transaction based approach is utilized in some methodologies in business process modeling. Essential parts of these transactions are human beings. The notion of agent or actor role is usually used for them. The paper on a particular example describes possibilities of Design Engineering Methodology for Organizations (DEMO) and Resource-Event-Agent (REA) methodology. Whereas the DEMO methodology can be regarded as a generic methodology having its foundation in the theory of Enterprise Ontology the REA methodology is regarded as the domain specific methodology and has its origin in accountancy systems. The results of these approaches is that the DEMO methodology captures everything that happens in the reality with a good empirical evidence whereas the REA methodology captures only changes connected with economic events. Economic events represent either change of the property rights to economic resource or consumption or production of economic resources. This results from the essence of economic events and their connection to economic resources.

    2015-01-01

    It is well known that public safety workers (PSW) face many stressful situations that yield them as high-risk population for suffering chronic stress diseases. In this multidisciplinary research the cardiac response to induced psychological stress by a short duration Stroop test was evaluated in 20 female and 19 male PSW, in order to compare traditionally used cardiac response parameters with alternative ones. Electrocardiograms have been recorded using the Eindhoven electrodes configuration for 1 min before, 3 min during and 1 min after the test. Signals analysis has been performed for the heart rate and the power spectra of its variability and of the variability of the amplitude of the R-wave, i.e. the highest peak of the electrocardiographic signal periodic sequence. The results demonstrated that the traditional autonomic balance index shows no significant differences between stages. In contrast, the median of the area of the power spectrum of the R-wave amplitude variability in the frequency region dominated by the autonomous nervous system (0.04-to-0.4 Hz) is the more sensitive parameter. Moreover, this parameter allows to identify gender differences consistent with those encountered in other studies.

  18. Contribution of psychology to the safety of installations with a high hazard potential; Beitrag der Psychologie zur Sicherheit von Einrichtungen hohen Gefaehrdungspotentials

    Energy Technology Data Exchange (ETDEWEB)

    Wilpert, B. [ed.

    1996-12-31

    Installations with a high hazard potential are usually characterised by the dual attribute `low risk - high hazard`. Diverse strategies of safety management are employed in such installations in order to limit the great hazard potential of safety-relevant occurrences (faults, abnormal operating states, accidents) that can take place in them. These strategies include specific control principles. In nuclear engineering, for example, the feedforward principle has already been used for some time as a tool of analytic risk determination (e.g., in probabilistic Safety Analysis (PSA) or Human Reliability Analysis (HRA)). A further example of these strategies of safety management is the empirical determination of risks through evaluation of operating experience (feedback control, e.g., epemiological studies, accident analysis) and, derived from this, identification of the system`s weak points in terms of safety. Insights derived from the application of these control principles can serve to develop specific means of intervention. These will tend to be closely oriented to the results obtained with the control method and may consist in, e.g., trainings or measures of organisation development. Independent of this, it will also be possible to identify long-term measures for preventing safety-relevant occurrences (e.g., organisational learning, safety-mindedness). The above-named strategies of safety management (control, intervention, prevention) provide a fertile basis for psychological studies in fields such as the physiology and psychology of perception (information processing), cognitive, psychology (thought and action), social psychology (division of labour, norms), paedagogic psychology (training), or organisational and environmental psychology (safety-mindedness, leadership, environmental influences).

    Full Text Available Financing (funding is essentially the purchase of funds necessary for a business. This can be done from internal sources (company’s own funds or external (borrowed funds. The high value of goods traded in international trade makes revenues generated from internal resources not sufficient to settle the value of the goods. Thus, it is frequent to resort to borrowed funds. In International Business Transactions, external financing is done both by classical techniques of credit (credit supplier and buyer credit and modern techniques of financing (factoring, forfeiting, leasing all trade tailored. In terms of the length of financing, accounting funding is short-term (1-12 months and long-term financing (over a year. In principle, export and import operations prevailing short-term financing techniques, while international investment and industrial cooperation actions are specific long-term funding

  3. Principles of Transactional Memory The Theory

    CERN Document Server

    Guerraoui, Rachid

    2010-01-01

    Transactional memory (TM) is an appealing paradigm for concurrent programming on shared memory architectures. With a TM, threads of an application communicate, and synchronize their actions, via in-memory transactions. Each transaction can perform any number of operations on shared data, and then either commit or abort. When the transaction commits, the effects of all its operations become immediately visible to other transactions; when it aborts, however, those effects are entirely discarded. Transactions are atomic: programmers get the illusion that every transaction executes all its operati

    2012-12-01

    Family medicine providers at a large family medicine clinic were surveyed regarding their impression of the impact, utility and safety of the Primary Care Prescribing Psychologist (PCPP) model in which a prescribing psychologist is embedded in a primary care clinic. This article describes the model and provides indications of its strengths and weaknesses as reported by medical providers who have utilized the model for the past 2 years. A brief history of prescribing psychology and the challenges surrounding granting psychologists the authority to prescribe psychotropic medication is summarized. Results indicate family medicine providers agree that having a prescribing psychologist embedded in the family medicine clinic is helpful to their practice, safe for patients, convenient for providers and for patients, and improves patient care. Potential benefits of integrating prescribing psychology into primary care are considered and directions for future research are discussed.

    Depression in elderly people is a major public health concern. As response to antidepressants is often unsatisfactory in this age group, there is a need for evidence-based non-pharmacological treatment options. Our objectives were twofold: firstly, to synthesize published trials evaluating efficacy, safety and cost-effectiveness of psychological treatment of depression in the elderly and secondly, to assess the quality of evidence. The electronic databases PubMed, EMBASE, Cochrane Library, CINAL, Scopus, and PsycINFO were searched up to 23 May 2016 for randomized controlled trials (RCTs) of psychological treatment for depressive disorders or depressive symptoms in people aged 65 years and over. Two reviewers independently assessed relevant studies for risk of bias. Where appropriate, the results were synthesized in meta-analyses. The quality of the evidence was graded according to GRADE (Grading of Recommendations Assessment, Development and Evaluation). Twenty-two relevant RCTs were identified, eight of which were excluded from the synthesis due to a high risk of bias. Of the remaining trials, six evaluated problem-solving therapy (PST), five evaluated other forms of cognitive behavioural therapy (CBT), and three evaluated life review/reminiscence therapy. In frail elderly with depressive symptoms, the evidence supported the efficacy of PST, with large but heterogeneous effect sizes compared with treatment as usual. The results for life-review/reminiscence therapy and CBT were also promising, but because of the limited number of trials the quality of evidence was rated as very low. Safety data were not reported in any included trial. The only identified cost-effectiveness study estimated an incremental cost per additional point reduction in Beck Depression Inventory II score for CBT compared with talking control and treatment as usual.

  8. How to increase the benefits of cooperation: Effects of training in transactive communication on cooperative learning.

    Science.gov (United States)

    Jurkowski, Susanne; Hänze, Martin

    2015-09-01

    Transactive communication means referring to and building on a learning partner's idea, by, for example, extending the partner's idea or interlinking the partner's idea with an idea of one's own. This transforms the partner's idea into a more elaborate one. Previous research found a positive relationship between students' transactive communication and their learning results when working in small groups. To increase the benefits of cooperation, we developed and tested a module for training students in transactive communication. We assumed that this training would enhance students' transactive communication and also increase their knowledge acquisition during cooperative learning. Further, we distinguished between an actor's transactive communication and a learning partner's transactive communication and expected both to be positively associated with an actor's knowledge acquisition. Participants were 80 university students. In an experiment with pre- and post-test measurements, transactive communication was measured by coding students' communication in a cooperative learning situation before training and in another cooperative learning situation after training. For the post-test cooperative learning situation, knowledge was pre-tested and post-tested. Trained students outperformed controls in transactive communication and in knowledge acquisition. Positive training effects on actors' knowledge acquisition were partially mediated by the improved actors' transactive communication. Moreover, actors' knowledge acquisition was positively influenced by learning partners' transactive communication. Results show a meaningful increase in the benefits of cooperation through the training in transactive communication. Furthermore, findings indicate that students benefit from both elaborating on their partner's ideas and having their own ideas elaborated on. © 2015 The British Psychological Society.

      “Safety is the highest priority”: this statement from CERN is endorsed by the CMS management. An interpretation of this statement may bring you to the conclusion that you should stop working in order to avoid risks. If the safety is the priority, work is not! This would be a misunderstanding and misinterpretation. One should understand that “working safely” or “operating safely” is the priority at CERN. CERN personnel are exposed to different hazards on many levels on a daily basis. However, risk analyses and assessments are done in order to limit the number and the gravity of accidents. For example, this process takes place each time you cross the road. The hazard is the moving vehicle, the stake is you and the risk might be the risk of collision between both. The same principle has to be applied during our daily work. In particular, keeping in mind the general principles of prevention defined in the late 1980s. These principles wer...

    Fire Safety – Essential for a particle detector The CMS detector is a marvel of high technology, one of the most precise particle measurement devices we have built until now. Of course it has to be protected from external and internal incidents like the ones that can occur from fires. Due to the fire load, the permanent availability of oxygen and the presence of various ignition sources mostly based on electricity this has to be addressed. Starting from the beam pipe towards the magnet coil, the detector is protected by flooding it with pure gaseous nitrogen during operation. The outer shell of CMS, namely the yoke and the muon chambers are then covered by an emergency inertion system also based on nitrogen. To ensure maximum fire safety, all materials used comply with the CERN regulations IS 23 and IS 41 with only a few exceptions. Every piece of the 30-tonne polyethylene shielding is high-density material, borated, boxed within steel and coated with intumescent (a paint that creates a thick co...

    Acquati, Chiara; Kayser, Karen

    2017-07-01

    The present study examined prevalence and predictors of psychological distress among cancer patients receiving care at a safety-net institution during the first year of implementation of a distress screening protocol. Differences between screened and unscreened patients were also analyzed. Data on 182 breast and lung cancer patients who were treated at a NCI-designated Academic Comprehensive Cancer Center (ACAD) were abstracted from the patients' medical charts for a period of 1 year. Among the patients screened for distress, 66.2% reported a score higher than 4 (the established cut-off for distress) on the Distress Thermometer. Results from multiple regression analysis indicated that younger age, practical, and emotional problems were significant predictors of higher self-reported scores of psychological distress. There were no significant differences on socio-demographic and clinical variables between patients screened and those who were not screened. However, patients who were receiving more than one treatment modality were more likely to be screened. The occurrence of psychological distress in this setting was higher than the percentages reported in other similar studies. Furthermore, younger cancer patients and those presenting psychosocial problems were at risk for higher distress, which requires referral to psychosocial providers and the implementation of services able to meet these areas of need.

  13. Sustainability Standards and the Reorganization of Private Label Supply Chains: A Transaction Cost Perspective

    2013-12-01

    Full Text Available Private standards are among the main measures that can be implemented to differentiate food production. Retailers have been particularly active in setting food safety and quality systems for the development of their private labels. The purpose of this paper is to identify the effects of introducing measures that guarantee the environmental sustainability of food production on vertical dyadic relations. We focus our attention on the adoption of integrated pest management (IPM systems that are designed by retailers to support private label products, with the aim of studying how these systems affect the governance structure of transactions between retailer and farmer/processor. Transaction cost analysis is used as theoretical framework to assess changes in vertical coordination after the adoption of an IPM system. Four case studies related to food retailers in Italy were analyzed to identify changes in transaction characteristics, costs, and governance that are related to the adoption of this system. The results show that the introduction of an IPM system leads to an increase of transaction asset specificity (i.e., especially of human and material asset specificity among the agents of the supply chain, and a decrease of the degree of transaction uncertainty. The variations in transaction characteristics determine changes in transaction costs. These changes lead to new hybrid forms of transaction governance, namely dyadic contracts, and a centralized organization of vertical relationships.

  14. Transaction Cost and Activity of Economic Agents

    2017-03-01

    Full Text Available The goal of the present paper is to clarify the role of transaction cost for existence of an economic agent. It is demonstrated that the opposition of transaction cost and transformation cost is not rigid and there are costs that contain both transaction and transformation component. In addition the amount of transaction cost depends on parameters of company’s activity. This is why it is hardly possible to find the precise minimum of transaction cost and the model of organization of transactions within firm will be flexible. The firm’s structure contains special transaction divisions (centers of transaction cost that are necessary for existence of the firm as a mechanism of organization of transactions (opposed to market. The status of these divisions depends on firm’s size. Transaction divisions can also exist outside the firm. They will minimize transaction costs of other economic agents on the basis of external effect of scale. External transaction divisions can exist both as collective structures (coordinating centers of strategic alliances as well as independent ones (franchisors. A comparative analysis of transaction divisions and centers of cost was done. It was demonstrated that these elements of the firm have different economic and organizational structure. The notion of cost of external profitability was introduced. This notion can be used to analyze reasons for merger of companies or for their existence as independent structures. It is demonstrated that one of the functions of the firm is to use resources that cannot be used within independent production units.

  15. HTML thin client and transactions

    Touchette, J F

    1999-01-01

    When writing applications for thin clients such as Web browsers, you face several challenges that do not exist with fat-client applications written in Visual Basic, Delphi, or Java. For one thing, your development tools do not include facilities for automatically building reliable, nonrepeatable transactions into applications. Consequently, you must devise your own techniques to prevent users from transmitting duplicate transactions. The author explains how to implement reliable, nonrepeatable transactions using a technique that is applicable to any Java Server Development Kit based architecture. Although the examples presented are based on the IBM WebSphere 2.1 Application Server, they do not make use of any IBM WebSphere extensions. In short, the concepts presented here can be implemented in Perl CGI and ASP scripts, and the sample code has been tested with JDK 1.1.6 and 1.2. (0 refs).

    Maksimović Viktor

    2009-01-01

    Full Text Available The new method developed in this paper is aiming at transmission congestion management (CM. The new, Optimal Transactions Management method (OTM, is based on linear programming (LP, DC load flow (DCLF and linear security constraints. The OTM method is embedded in Available Transfer Capabilities (ATCs and Power Transfer Distribution Factors (PTDFs definitions' environment. Well-suited for both preventive and corrective modes of operation, the OTM method aids transmission system operator in running a congested power system network, where congestions are due to transactions. Potential congestion threat is solved by finding the 'culprit' transaction and its optimal reduction. Besides the proposed downsizing of scheduled and/or committed transactions, controls of the OTM method also include redispatching of generation and load levels. The task is to establish a system state without constraint violations. To ensure the feasible network solution, both DC and AC power flows are used. The common 5 nodes/7 lines Ward&Hale sample power system is used to clarify the OTM method. Besides, six other power system networks including the real-life power system network of Serbia, Macedonia and Montenegro (part of the South East Europe - SEE grid are used to test remedial potentials and CPU-time performances of the method. The 24-hour daily demand diagram is used with all test networks to study the effects of transactions as they are being superimposed to the regional grid. The remedial, transactions-curtailing OTM method is found well suited for market-related analyses precluding the hour-ahead, the day-ahead dispatch, as well as the real-time generation dispatch. It could also suit for the novel, Day Ahead Congestion Forecast (DACF procedure used in power markets. .

    2017-07-01

    Substantial number of the current information system (IS) implementations is based on transaction approach. In addition, most of the implementations are domain-specific (e.g. accounting IS, resource planning IS). Therefore, we have to have a generic transaction model to build and verify domain-specific IS. The paper proposes a new transaction model for domain-specific ontologies. This model is based on value oriented business process modelling technique. The transaction model is formalized by the Petri Net theory. First part of the paper presents common business processes and analyses related to business process modeling. Second part defines the transactional model delimited by REA enterprise ontology paradigm and introduces states of the generic transaction model. The generic model proposal is defined and visualized by the Petri Net modelling tool. Third part shows application of the generic transaction model. Last part of the paper concludes results and discusses a practical usability of the generic transaction model.

    2014-12-01

    The transactional paradigm states that people create, maintain, and change their environments according to their personalities. At the same time, the environment reacts back on personality. As social relationships are part of an individual's environment, this likewise implies that there are reciprocal transactions between personality and relationships. However, earlier studies have concluded that adult personality traits are so stable that they have a stronger effect on later relationships, but that relationship effects on personality are negligible. In this article, we contend that personality-relationship transactions should be revisited. We submit that the relative powers of personality versus relationship effects depend on the type of life transition during which the effects take place: Relationship effects on personality development are more likely to emerge in the context of rather normative and highly scripted life transitions, whereas personality effects on relationship development are more likely to occur in the context of rather non-normative life transitions that are less regulated by social expectations. We illustrate these assumptions with examples from our own work and other findings reported in the literature. Furthermore, we theorize that effects of personality-relationship transactions on health also vary with the normativeness of the eliciting life transition. © 2013 Wiley Periodicals, Inc.

    Abstract This work presents a systemic top-down visualization of Bitcoin transaction activity to explore dynamically generated patterns of algorithmic behavior. Bitcoin dominates the cryptocurrency markets and presents researchers with a rich source of real-time transactional data. The pseudonymous yet public nature of the data presents opportunities for the discovery of human and algorithmic behavioral patterns of interest to many parties such as financial regulators, protocol designers, and security analysts. However, retaining visual fidelity to the underlying data to retain a fuller understanding of activity within the network remains challenging, particularly in real time. We expose an effective force-directed graph visualization employed in our large-scale data observation facility to accelerate this data exploration and derive useful insight among domain experts and the general public alike. The high-fidelity visualizations demonstrated in this article allowed for collaborative discovery of unexpected high frequency transaction patterns, including automated laundering operations, and the evolution of multiple distinct algorithmic denial of service attacks on the Bitcoin network.

  10. Identifying Bitcoin users by transaction behavior

    Science.gov (United States)

    Monaco, John V.

    2015-05-01

    Digital currencies, such as Bitcoin, offer convenience and security to criminals operating in the black marketplace. Some Bitcoin marketplaces, such as Silk Road, even claim anonymity. This claim contradicts the findings in this work, where long term transactional behavior is used to identify and verify account holders. Transaction timestamps and network properties observed over time contribute to this finding. The timestamp of each transaction is the result of many factors: the desire purchase an item, daily schedule and activities, as well as hardware and network latency. Dynamic network properties of the transaction, such as coin flow and the number of edge outputs and inputs, contribute further to reveal account identity. In this paper, we propose a novel methodology for identifying and verifying Bitcoin users based on the observation of Bitcoin transactions over time. The behavior we attempt to quantify roughly occurs in the social band of Newell's time scale. A subset of the Blockchain 230686 is taken, selecting users that initiated between 100 and 1000 unique transactions per month for at least 6 different months. This dataset shows evidence of being nonrandom and nonlinear, thus a dynamical systems approach is taken. Classification and authentication accuracies are obtained under various representations of the monthly Bitcoin samples: outgoing transactions, as well as both outgoing and incoming transactions are considered, along with the timing and dynamic network properties of transaction sequences. The most appropriate representations of monthly Bitcoin samples are proposed. Results show an inherent lack of anonymity by exploiting patterns in long-term transactional behavior.

    Transactional sex refers to the commodification of the body in exchange for shelter, food, and other goods and needs. Transactional sex has been associated with negative health outcomes including HIV infection, psychological distress, and substance use and abuse. Compared with the body of research examining transactional sex among women, less is known about the prevalence and correlates of transactional sex among men. Using data from a cross-sectional survey of young men who have sex with men (ages 18-29) living in the Detroit Metro Area ( N = 357; 9% HIV infected; 49% Black, 26% White, 16% Latino, 9% Other race), multivariate logistic regression analyses examined the association between transactional sex with regular and casual partners and key psychosocial factors (e.g., race/ethnicity, education, poverty, relationship status, HIV status, prior sexually transmitted infections [STIs], mental health, substance use, and residential instability) previously identified in the transactional sex literature. Forty-four percent of the current sample reported engaging in transactional sex. Transactional sex was associated with age, employment status, relationship status, and anxiety symptoms. When stratified, transactional sex with a regular partner was associated with age, educational attainment, employment status, relationship status, anxiety, and alcohol use. Transactional sex with a casual partner was associated with homelessness, race/ethnicity, employment status, and hard drug use. The implications of these findings for HIV/STI prevention are discussed, including the notion that efforts to address HIV/STIs among young men who have sex with men may require interventions to consider experiences of transactional sex and the psychosocial contexts that may increase its likelihood.

  12. The consequences of hospital autonomization in Colombia: a transaction cost economics analysis.

    Science.gov (United States)

    Castano, Ramon; Mills, Anne

    2013-03-01

    Granting autonomy to public hospitals in developing countries has been common over recent decades, and implies a shift from hierarchical to contract-based relationships with health authorities. Theory on transactions costs in contractual relationships suggests they stem from relationship-specific investments and contract incompleteness. Transaction cost economics argues that the parties involved in exchanges seek to reduce transaction costs. The objective of this research was to analyse the relationships observed between purchasers and the 22 public hospitals of the city of Bogota, Colombia, in order to understand the role of relationship-specific investments and contract incompleteness as sources of transaction costs, through a largely qualitative study. We found that contract-based relationships showed relevant transaction costs associated mainly with contract incompleteness, not with relationship-specific investments. Regarding relationships between insurers and local hospitals for primary care services, compulsory contracting regulations locked-in the parties to the contracts. For high-complexity services (e.g. inpatient care), no restrictions applied and relationships suggested transaction-cost minimizing behaviour. Contract incompleteness was found to be a source of transaction costs on its own. We conclude that transaction costs seemed to play a key role in contract-based relationships, and contract incompleteness by itself appeared to be a source of transaction costs. The same findings are likely in other contexts because of difficulties in defining, observing and verifying the contracted products and the underlying information asymmetries. The role of compulsory contracting might be context-specific, although it is likely to emerge in other settings due to the safety-net role of public hospitals.

  15. Correctness of Concurrent Executions of Closed Nested Transactions in Transactional Memory Systems

    Science.gov (United States)

    Peri, Sathya; Vidyasankar, Krishnamurthy

    A generally agreed upon requirement for correctness of concurrent executions in Transactional Memory systems is that all transactions including the aborted ones read consistent values. Opacity is a recently proposed correctness criterion that satisfies the above requirement. Our first contribution in this paper is extending the opacity definition for closed nested transactions. Secondly, we define conflicts appropriate for optimistic executions which are commonly used in Software Transactional Memory systems. Using these conflicts, we define a restricted, conflict-preserving, class of opacity for closed nested transactions the membership of which can be tested in polynomial time. As our third contribution, we propose a correctness criterion that defines a class of schedules where aborted transactions do not affect consistency of the other transactions. We define a conflict-preserving subclass of this class as well. Both the class definitions and the conflict definition are new for nested transactions.

    Using a longitudinal, randomized controlled trial, this study assessed the impact of a community-based outreach versus a more traditional criminal justice system-based referral program on women's distress and safety following police-reported intimate partner abuse (IPA). Women (N = 236 women) with police-reported IPA were randomly assigned to 1 of 2 interdisciplinary community-coordinated response program conditions: Outreach (community-based victim advocate outreach) or Referral (criminal justice system-based victim advocate referrals to community-based agencies). Participants were interviewed 3 times over a 1-year period: within 26 (median) days of police-reported IPA, 6 months later, and 12 months later. Primary outcome measures included posttraumatic stress disorder and depression symptom severity (Posttraumatic Stress Diagnostic Scale; Beck Depression Inventory-II), fear appraisals (Trauma Appraisal Questionnaire), IPA revictimization (Revised Conflict Tactics Scale), and readiness to leave the relationship with the abuser. One year after the initial interview, women in the Outreach condition reported decreased PTSD and depression symptom severity and fear compared with women in the Referral condition. Although both conditions were unrelated to revictimization in the follow-up year, women in the Outreach condition reported greater readiness to leave the abuser and rated services as more helpful than women in the Referral condition. This is one of the first studies to examine community-based outreach in the context of an interdisciplinary community coordinated response to police-reported IPA. The findings suggest that community-based outreach by victim advocates results in decreased distress levels, greater readiness to leave abusive relationships, and greater perceived helpfulness of services relative to system-based referrals.

    Full Text Available Transactional events (TE are an extension of Concurrent ML (CML, a programming model for synchronous message-passing. Prior work has focused on TE's formal semantics and its implementation. This paper considers programming idioms, particularly those that vary unexpectedly from the corresponding CML idioms. First, we solve a subtle problem with client-server protocols in TE. Second, we argue that CML's wrap and guard primitives do not translate well to TE, and we suggest useful workarounds. Finally, we discuss how to rewrite CML protocols that use abort actions.

    2016-11-01

    Money flow models are essential tools to understand different economical phenomena, like saving propensities and wealth distributions. In spite of their importance, most of them are based on synthetic transaction networks with simple topologies, e.g. random or scale-free ones, as the characterisation of real networks is made difficult by the confidentiality and sensitivity of money transaction data. Here, we present an analysis of the topology created by real credit card transactions from one of the biggest world banks, and show how different distributions, e.g. number of transactions per card or amount, have nontrivial characteristics. We further describe a stochastic model to create transactions data sets, feeding from the obtained distributions, which will allow researchers to create more realistic money flow models.

    Filip K Arnberg

    Full Text Available BACKGROUND: Greater access to evidence-based psychological treatments is needed. This review aimed to evaluate whether internet-delivered psychological treatments for mood and anxiety disorders are efficacious, noninferior to established treatments, safe, and cost-effective for children, adolescents and adults. METHODS: We searched the literature for studies published until March 2013. Randomized controlled trials (RCTs were considered for the assessment of short-term efficacy and safety and were pooled in meta-analyses. Other designs were also considered for long-term effect and cost-effectiveness. Comparisons against established treatments were evaluated for noninferiority. Two reviewers independently assessed the relevant studies for risk of bias. The quality of the evidence was graded using an international grading system. RESULTS: A total of 52 relevant RCTs were identified whereof 12 were excluded due to high risk of bias. Five cost-effectiveness studies were identified and three were excluded due to high risk of bias. The included trials mainly evaluated internet-delivered cognitive behavioral therapy (I-CBT against a waiting list in adult volunteers and 88% were conducted in Sweden or Australia. One trial involved children. For adults, the quality of evidence was graded as moderate for the short-term efficacy of I-CBT vs. waiting list for mild/moderate depression (d = 0.83; 95% CI 0.59, 1.07 and social phobia (d = 0.85; 95% CI 0.66, 1.05, and moderate for no efficacy of internet-delivered attention bias modification vs. sham treatment for social phobia (d =  -0.04; 95% CI -0.24, 0.35. The quality of evidence was graded as low/very low for other disorders, interventions, children/adolescents, noninferiority, adverse events, and cost-effectiveness. CONCLUSIONS: I-CBT is a viable treatment option for adults with depression and some anxiety disorders who request this treatment modality. Important questions remain before broad

    2004-12-01

    The importance of leadership for effective safety management has been the focus of research attention in industry for a number of years, especially in energy and manufacturing sectors. In contrast, very little research into leadership and safety has been carried out in medical settings. A selective review of the industrial safety literature for leadership research with possible application in health care was undertaken. Emerging findings show the importance of participative, transformational styles for safety performance at all levels of management. Transactional styles with attention to monitoring and reinforcement of workers' safety behaviours have been shown to be effective at the supervisory level. Middle managers need to be involved in safety and foster open communication, while ensuring compliance with safety systems. They should allow supervisors a degree of autonomy for safety initiatives. Senior managers have a prime influence on the organisation's safety culture. They need to continuously demonstrate a visible commitment to safety, best indicated by the time they devote to safety matters.

  19. The Secret Life of Mundane Transaction Costs

    OpenAIRE

    Richard N. Langlois

    2005-01-01

    Transaction costs, one often hears, are the economic equivalent of friction in physical systems. Like physicists, economists can sometimes neglect friction in formulating theories; but like engineers, they can never neglect friction in studying how the system actually does let alone should work. Interestingly, however, the present-day economics of organization also ignores friction. That is, almost single-mindedly, the literature analyzes transactions from the point of view of misaligned ince...

    Electronic commerce is a large and ever growing industry. Online transactions are returning ever-growing revenues to electronic merchants. The e-commerce industry is still facing a range of problems concerning the process of completion of online transactions. Such problems are connected to consumer fears dealing with the identity of online merchants, their security pre- cautions and methods for accepting online payments. This thesis develops and presents a Mutual Authentication Model (MAM), w...

  6. Optimizing Concurrent M3-Transactions: A Fuzzy Constraint Satisfaction Approach

    Directory of Open Access Journals (Sweden)

    Peng LI

    2004-10-01

    Full Text Available Due to the high connectivity and great convenience, many E-commerce application systems have a high transaction volume. Consequently, the system state changes rapidly and it is likely that customers issue transactions based on out-of-date state information. Thus, the potential of transaction abortion increases greatly. To address this problem, we proposed an M3-transaction model. An M3-transaction is a generalized transaction where users can issue their preferences in a request by specifying multiple criteria and optional data resources simultaneously within one transaction. In this paper, we introduce the transaction grouping and group evaluation techniques. We consider evaluating a group of M3-transactions arrived to the system within a short duration together. The system makes optimal decisions in allocating data to transactions to achieve better customer satisfaction and lower transaction failure rate. We apply the fuzzy constraint satisfaction approach for decision-making. We also conduct experimental studies to evaluate the performance of our approach. The results show that the M3-transaction with group evaluation is more resilient to failure and yields much better performance than the traditional transaction model.

  7. The Econometric Procedures of Specific Transaction Identification

    Directory of Open Access Journals (Sweden)

    Doszyń Mariusz

    2017-06-01

    Full Text Available The paper presents the econometric procedures of identifying specific transactions, in which atypical conditions or attributes may occur. These procedures are based on studentized and predictive residuals of the accordingly specified econometric models. The dependent variable is a unit transactional price, and explanatory variables are both the real properties’ attributes and accordingly defined artificial binary variables. The utility of the proposed method has been verified by means of a real market data base. The proposed procedures can be helpful during the property valuation process, making it possible to reject real properties that are specific (both from the point of view of the transaction conditions and the properties’ attributes and, consequently, to select an appropriate set of similar attributes that are essential for the valuation process.

  8. Implementing e-Transactions with Asynchronous Replication

    An e-Transaction is one that executes exactly-once despite failures. This paper describes a distributed protocol that implements the abstraction of e-Transactionsin three-tier architectures. Three-tier architectures are typically Internet-oriented architectures, where the end-user interacts with front-end clients (e.g., browsers) that invoke middle-tier application servers (e.g., web servers) to access back-end databases. We implement the e-Transaction abstraction using an asynchronous replic...

    Plural governance is a form of governance where a firm both makes and buys similar goods or services. Despite a widespread use of plural governance there are no transaction cost models of how plural governance affects performance. This paper reviews the literature about plural forms and proposes...... a model relating transaction cost and resource-based variables to the cost of the plural form. The model is then used to analyze when the plural form is efficient compared to alternative governance structures. We also use the model to discuss the strength of three plural form synergies....

    2001-10-01

    The advent of the Electronic Data Interchange (EDI) and the Internet with its subsequent use in the field of supply chains, mainly online shopping; web managed purchasing and online auctions have given rise to complex relationships between buyers and suppliers. The manner in which the buyer-supplier transactions occur have a psychological bearing similar to the transactions occurring between humans in the buyer-supplier organizations. The on-going research to study the psychological aspects of the transactions will use Transactional Analysis as a tool to identify these aspects of the relationship. The essential aspect of this view is that organizational culture plays a very strong role in the way organizations operate, and when two organizations transact with each other the individual culture is bound to play a role in the way the transaction is conducted. There are a number of factors that play a role in bringing the culture to the forefront of the transaction process. It is necessary to study these factors in order to understand why the psychological behavior is actually shown by these buyer- supplier organizations.

    2017-01-01

    Full Text Available The primary purpose of this study was to explore how food dealers develop methods that facilitate transaction efficiency and how they select the optimal food channels. This study establishes a model according to the impact of transaction cost factors on consumers’ decision-making regarding purchase of fresh snack foods. Using fresh snack foods in Taiwan as an example, this study employed a fuzzy analytic network process to solve decision-making problems with multiple criteria by comparing the interaction between each transaction cost factor to obtain the factor weightings as well as the weightings of the transaction costs at each decision stage. This study found that food safety assurance and providing sufficient nutrition information were the most essential topics; thus, the optimal choice for snack food producers is to develop retail outlets. This study construction process proposed is innovative and operational, and the results may provide a reference for snack food dealers or microfood enterprises to assist them in developing their food channels.

    Transactive energy refers to the combination of economic and control techniques to improve grid reliability and efficiency. The fundamental purpose of transactive energy management is to seamlessly coordinate the operation of large numbers of new intelligent assets—such as distributed solar, energy storage and responsive building loads—to provide the flexibility needed to operate the power grid reliably and at minimum cost, particularly one filled with intermittent renewable generation such as the Pacific Northwest. It addresses the key challenge of providing smooth, stable, and predictable “control” of these assets, despite the fact that most are neither owned nor directly controlled by the power grid. The Clean Energy and Transactive Campus (CETC) work described in this report was done as part of a Cooperative Research and Development Agreement (CRADA) between the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) and the Washington State Department of Commerce (Commerce) through the Clean Energy Fund (CEF). The project team consisted of PNNL, the University of Washington (UW) and Washington State University (WSU), to connect the PNNL, UW, and WSU campuses to form a multi-campus testbed for transaction-based energy management—transactive—solutions. Building on the foundational transactive system established by the Pacific Northwest Smart Grid Demonstration (PNWSGD), the purpose of the project was to construct the testbed as both a regional flexibility resource and as a platform for research and development (R&D) on buildings/grid integration and information-based energy efficiency. This report provides a summary of the various tasks performed under the CRADA.

    The importance of effective communication, a key component of teamwork, is well recognised in the healthcare setting. Establishing a culture that encourages and empowers team members to speak openly in the cardiothoracic (CT) operating room (OR) is necessary to improve patient safety in this high-risk environment. This study will take place at Barnes-Jewish Hospital, an academic hospital in affiliation with Washington University School of Medicine located in the USA. All team members participating in cardiac and thoracic OR cases during this 17-month study period will be identified by the primary surgical staff attending on the OR schedule.TeamSTEPPS (Team Strategies and Tools to Enhance Performance and Patient Safety) training course will be taught to all CT OR staff. Before TeamSTEPPS training, staff will respond to a 39-item questionnaire that includes constructs from the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture, Edmondson's 'Measure of psychological safety' questionnaire, and questionnaires on turnover intentions, job satisfaction and 'burnout'. The questionnaires will be readministered at 6 and 12 months.The primary outcomes to be assessed include the perceived psychological safety of CT OR team members, the overall effect of TeamSTEPPS on burnout and job satisfaction, and observed turnover rate among the OR nurses. As secondary outcomes, we will be assessing self-reported rates of medical error and near misses in the ORs with a questionnaire at the end of each case. Ethics approval is not indicated as this project does not meet the federal definitions of research requiring the oversight of the Institutional Review Board (IRB). Patient health information (PHI) will not be generated during the implementation of this project. Results of the trial will be made accessible to the public when published in a peer-reviewed journal following the completion of the study. © Article author(s) (or their employer(s) unless

    This document proposes a framework concept to achieve the objectives of raising buildings’ efficiency and energy savings potential benefitting building owners and operators. We call it a transaction-based framework, wherein mutually-beneficial and cost-effective market-based transactions can be enabled between multiple players across different domains. Transaction-based building controls are one part of the transactional energy framework. While these controls realize benefits by enabling automatic, market-based intra-building efficiency optimizations, the transactional energy framework provides similar benefits using the same market -based structure, yet on a larger scale and beyond just buildings, to the society at large.

    2013-01-01

    BitCoin transactions are malleable in a sense that given a transaction an adversary can easily construct an equivalent transaction which has a different hash. This can pose a serious problem in some BitCoin distributed contracts in which changing a transaction's hash may result in the protocol disruption and a financial loss. The problem mostly concerns protocols, which use a "refund" transaction to withdraw a deposit in a case of the protocol interruption. In this short note, we show a gener...

    In palliative care hospitals in Japan, mechanical bathing is conducted to maintain cleanliness. However, the physiological and psychological influence of mechanical bathing on patients has not been sufficiently studied. The objective of this study was to assess, using physiological and psychological indices, the effects of mechanical bathing care for patients in the terminal stage of cancer. Mechanical bathing was performed using a Marine Court SB7000 in a supine or semi-seated position. The heart rate variability analysis method was used to measure autonomic nervous system function. The patients' state of anxiety was assessed using the State-Trait Anxiety Inventory (STAI), a psychological index, and patients' verbal responses were also collected after mechanical bathing. Twenty-four patients were enrolled in this study. Their sympathetic and parasympathetic nervous activity did not differ before and after bathing. A significant difference was found between pre- and post-bathing anxiety, as evaluated by STAI (P mechanical bathing according to STAI evaluation and their verbal responses. The findings suggest that the method of bathing used in this study is safe and pain-relieving for terminal stage cancer patients. It is thus possible to provide safe and comfortable care for terminal stage cancer patients using mechanical baths.

  20. Market Model Considering Bilateral Transactions in the Deregulated Electricity Market

    Science.gov (United States)

    Ruiz Monroy, José Joaquín; Kita, Hiroyuki; Tanaka, Eiichi; Hasegawa, Jun

    This paper proposes an algorithm to simulate the transactions that take place in a free market of electricity. The algorithm presented is used for Bilateral Transaction Matrix (BTM) creation assuming that a day ahead load forecast is previously known. Bids can be made by both the generation side and the demand side to determine transaction prices, then the algorithm allocates the transactions according to market rules until the demand is satisfied. This creates feasible BTMs that can be used to study system security and to find future methods to regulate bilateral transactions through market mechanisms like the application of penalties to the transactions that affect the system’s security. Results show that the proposed algorithm is a good option for electricity market analysis. The proposed algorithm provides system planners with a practical tool for data creation to further study the effects of bilateral transactions in a deregulated electricity market.

    This document details the development and testing of market-based transactive controls for building heating, ventilating and air conditioning (HVAC) systems. These controls are intended to serve the purposes of reducing electricity use through conservation, reducing peak building electric demand, and providing demand flexibility to assist with power system operations. This report is the summary of the first year of work conducted under Phase 1 of the Clean Energy and Transactive Campus Project. The methods and techniques described here were first investigated in simulation, and then subsequently deployed to a physical testbed on the Pacific Northwest National Laboratory (PNNL) campus for validation. In this report, we describe the models and control algorithms we have developed, testing of the control algorithms in simulation, and deployment to a physical testbed. Results from physical experiments support previous simulation findings, and provide insights for further improvement.

  2. Transactional distance in a blended learning environment

    Directory of Open Access Journals (Sweden)

    2004-12-01

    Full Text Available This paper presents a case study that describes and discusses the problems encountered during the design and implementation of a blended learning course, largely taught online through a web-based learning environment. Based on Moore's theory of transactional distance, the course was explicitly designed to have dialogue at its heart. However, the reality of systemic behaviours caused by delivering such a course within a group of conventional further and higher educational institutions has led to an entirely unanticipated reversion to structure, with unpleasant consequences for both quality and quantity of dialogue. The paper looks at some of the reasons for this drift, and suggests that some of the disappointing results (in particular in terms of the quality of the students' experience and associated poor retention can be attributed to the lack of dialogue, and consequent increase in transactional distance. It concludes with a description and evaluation of steps currently being taken to correct this behaviour.

  3. The quantum handshake entanglement, nonlocality and transactions

    CERN Document Server

    Cramer, John G

    2016-01-01

    This book shines bright light into the dim recesses of quantum theory, where the mysteries of entanglement, nonlocality, and wave collapse have motivated some to conjure up multiple universes, and others to adopt a "shut up and calculate" mentality. After an extensive and accessible introduction to quantum mechanics and its history, the author turns attention to his transactional model. Using a quantum handshake between normal and time-reversed waves, this model provides a clear visual picture explaining the baffling experimental results that flow daily from the quantum physics laboratories of the world. To demonstrate its powerful simplicity, the transactional model is applied to a collection of counter-intuitive experiments and conceptual problems.

    This document is the second of a two-part report. Part 1 reviewed several demonstrations of transactive control and compared them in terms of their payoff functions, control decisions, information privacy, and mathematical solution concepts. It was suggested in Part 1 that these four listed components should be adopted for meaningful comparison and design of future transactive systems. Part 2 proposes qualitative and quantitative metrics that will be needed to compare alternative transactive systems. It then uses the analysis and design principles from Part 1 while conducting more in-depth analysis of two transactive demonstrations: the American Electric Power (AEP) gridSMART Demonstration, which used a double –auction market mechanism, and a consensus method like that used in the Pacific Northwest Smart Grid Demonstration. Ultimately, metrics must be devised and used to meaningfully compare alternative transactive systems. One significant contribution of this report is an observation that the decision function used for thermostat control in the AEP gridSMART Demonstration has superior performance if its decision function is recast to more accurately reflect the power that will be used under for thermostatic control under alternative market outcomes.

    In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters' attitudes, leaders' personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

  7. Transactional Neuropsychology, a Holistic View of Children with Developmental Disabilities

    Directory of Open Access Journals (Sweden)

    Gerardo Restrepo

    2015-09-01

    Full Text Available Introduction: The main objective of this article is to review some essential concepts to understan­ding the traditional way in which neuropsychology conceives difficulties in child development, and to propose an alternative model for integrally understanding this problematic. Development: Physicians, psychologists, therapists, and teachers conceive difficulties in development as a result of a neuro-biological problem that can be subject of identification and treatment. This premise, widely used currently by interdisciplinary staffs, is the prevailing focus and the traditional po­sition to evaluate and intervene in medicine, psychology and education. The traditional model, known as the deficit model, conceptualizes the difficulties in child development as being essentially neuro-biological, without considering the various aspects of both family and school environments, which are of paramount importance not only for the child development, but also in the genesis of its difficulties. This explains why efforts invested in the rehabilitation and education of the child with difficulties have a limited success. In contrast, the ecological or transactional neurop­sychology is an approach that considers the child in a comprehensive manner, relating with its social, family and cultural environment. Conclusion: Integrally conceptualizing and interpreting these phenomena leads to a holistic intervention where each element of the problem is assessed, leading to the proposal of a model in which the environment plays a crucial role in the genesis of the difficulties in child development, and the search for solutions.

    synchronization method scales well. Recently, hardware transactional memory was introduced, which allows threads to use transactions instead of locks. So far, applying hardware transactional memory has shown mixed results. We believe this is because transactions are different from locks, and using them...... efficiently requires reasoning about those differences. In this paper we present 5 guidelines for applying hardware transactional memory efficiently, and apply the guidelines to BT-trees, a concurrent ordered map. Evaluating BT-trees on standard benchmarks shows that they are up to 5.3 times faster than...... traditional maps using hardware transactional memory, and up to 3.9 times faster than state of the art concurrent ordered maps....

    2018-02-12

    This article delineates 2 separate but related subfields of psychological science and practice applicable across all major areas of the field (e.g., clinical, counseling, developmental, social, cognitive, community). Forensic and correctional psychology are related by their historical roots, involvement in the justice system, and the shared population of people they study and serve. The practical and ethical contexts of these subfields is distinct from other areas of psychology-and from one another-with important implications for ecologically valid research and ethically sound practice. Forensic psychology is a subfield of psychology in which basic and applied psychological science or scientifically oriented professional practice is applied to the law to help resolve legal, contractual, or administrative matters. Correctional psychology is a subfield of psychology in which basic and applied psychological science or scientifically oriented professional practice is applied to the justice system to inform the classification, treatment, and management of offenders to reduce risk and improve public safety. There has been and continues to be great interest in both subfields-especially the potential for forensic and correctional psychological science to help resolve practical issues and questions in legal and justice settings. This article traces the shared and separate developmental histories of these subfields, outlines their important distinctions and implications, and provides a common understanding and shared language for psychologists interested in applying their knowledge in forensic or correctional contexts.

    2012-12-01

    Full Text Available Abstract Background Given the high rate of adolescent smoking, cessation remains a vital public health priority. This study explored archival data using a structured phenomenological framework known as Reversal Theory (RT. In order to better understand aspects of adolescent tobacco use we compared the transactional, psychological states described by RT to the factor structure of adolescents’ self-reported social environment influencing tobacco use. Methods In a two step analysis of questions about self-reported tobacco use cognitions, attitudes, and behaviors from youth enrolled during the 2003–2004 period in a Texas, state-wide, mandated tobacco cessation program (N=1807, four factors and 11 items were identified as significantly related to the influence of social context and adolescents’ tobacco use. These first step results guided the items to be selected for further analysis. In step two the variables were subjected to a factor analysis using principal components extraction and varimax rotation. The resulting factor structure was compared and interpreted within the context of descriptions of RT transactional states. Results The analysis indicated that four factors were closely aligned to descriptions of the Reversal Theory transactional states and could be reinterpreted from within the framework of RT. The first factor included feelings of self-efficacy for quitting (autic mastery. The second and third transactional factors diverged between one factor to quit, and an opposing transactional factor to continue to smoke. Both of these transactional states are variants of the autocentric state where one wants to experience feelings of gain with the help of others. The fourth factor could be interpreted as ’confidence’ or ‘optimism’. Conclusions This intra-individual conflict revealed by the opposition of factors two and three clarifies a paradoxical issue where an adolescent wants to quit smoking with social support in one setting

    There are many studies, among them many case studies and those based on energy system modelling (bottom-up studies) - revealing technologies or engineering measures that can be applied today in order to reduce CO{sub 2} emissions, and which either are even profitable at that, or do not require additional investment. This 'no-regret' potential is denied in particular by analysts who favour the top-down approach in their energy systems analyses. Their argument is that essential costs are left unconsidered in cost analysis, namely the transaction and programme costs. The article examines from the angle of transaction cost economics the nature of the transaction costs and the approach taken in valuating and modelling the cost of energy efficiency measures. Further, the necessity and adequacy of integrating programme costs into such analyses is discussed. (orig./CB) [German] Viele Studien - darunter viele Fallstudien und Studien auf Basis von Energiesystemmodellen (Bottom-up-Studien) - weisen technische Massnahmen aus, mit denen schon heute CO{sub 2}-Emissionen vermieden und gleichzeitig noch Gewinne erzielt werden koennen oder fuer die zumindest keine zusaetzlichen Kosten entstehen. Dieses 'no-regret'-Potential wird vor allem von Analytikern der 'Top-down'-Ebene bestritten mit dem Argument, bei der Berechnung der wirtschaftlichen Potentiale wuerden wesentliche Kosten - naemlich Transaktions- und Programmkosten - nicht beruecksichtigt (Grubb et al. 1993). Dieser Aufsatz hinterfragt den in der Fachdiskussion inzwischen sehr oft und oft leichtfertig gebrauchten Begriff der Transaktionskosten und wirft einen kritischen Blick auf die Bewertung und Modellierung der Kosten von Energiesparmassnahmen aus Sicht der Transaktionskostenoekonomie. Ausserdem wird die Notwendigkeit und Moeglichkeit, Programmkosten in die Betrachtung zu integrieren, diskutiert. (orig.)

    Full Text Available Using a progressive Information Technology for development of Software Modules for Enterprise Information Systems brings a lot of practical and theoretical problems. One of them is a verification of results achieved in Life Cycle Stages. Object Oriented Analysis has the main position in the Object Life Cycle of Information Systems. It gives fundamental diagrams that will be processed in the Design and Implementation phases. We mention diagrams for enterprise processes and their refining to enterprise transaction diagrams. The Unified Modeling Language (UML has been very often used to enterprise processes and transactions modeling. There is one of very practical and theoretical problems concerning enterprise processes – their internal consistency that can be observed on the level of object transactions. We have in mind such problem as transaction feasibility and object cooperation feasibility in transactions that are strongly bound with states of objects. Therefore, a testing of object complex transactions before their programming appears to be very useful activity.This article introduces a formal description of the object cooperation logic. Therefore there is defined not only an elementary transaction feasibility but also an elementary object cooperation feasibility. It enables to search the feasibility of certain strings of elementary transactions and elementary object collaborations. One string of elementary transactions is very often regarded as a path. There are found two different systems of state logical equations. The first describes path transaction feasibility and the se- cond path object cooperation feasibility. The functional correctness of any complex transaction is founded on a functional correctness of all its paths.

The moderating role of contract types in these relationships was also tested. Findings supported a positive association between perceived psychological contract breach and felt violation and both were positively related to burnout. Transactional and relational contracts moderated the felt violation-burnout relationship. Scores on relational contract type tended to be higher than for transactional contract type showing some contextual influence.

  14. Whither Psychology.

    2017-07-01

    Contemporary psychology is experiencing tremendous growth in neuroscience, and there is every indication that it will continue to gain in popularity notwithstanding the scarcity of academic positions for newly minted Ph.Ds. Despite the general perception that brain correlates "explain" or "cause" the mind and behavior, these correlates have not yet proven useful in understanding psychological processes, although they offer the possibility of early identification of some disorders. Other recent developments in psychology include increased emphasis on applications and more global representation among researchers and participants. In thinking about the way we want psychology to evolve, psychologists need to pay more than lip service to the idea that complex questions in psychology require multiple levels of analysis with contributions from biological (brain, hormones, and genetics), individual differences and social and cultural perspectives. Early career psychologists who can attain a breadth of knowledge will be well-positioned for a team approach to psychological inquiry. Finally, I offer the belief that an emphasis on enhancing critical thinking skills at all levels of education offers the best hope for the future.

    and support. Hence, we use measures of a firm’s access to social networks as a proxy for the transaction costs the firm faces. We develop a microeconomic production model that takes into account transaction costs and networks. Using a data set of 384 Polish farms, we empirically estimate this model......We argue that in the presence of transaction costs, observed productivity measures may in many cases understate the true productivity, as production data seldom distinguish between resources entering the production process and resources of a similar type that are sacrificed for transaction costs....... Hence, both the absolute productivity measures and, more importantly, the productivity ranking will be distorted. A major driver of transaction costs is poor access to information and contract enforcement assistance. Social networks often catalyse information exchange as well as generate trust...

    Transactive energy systems use principles of value to coordinate responsive supply and demand in energy systems. Work continues within the Transactive Systems Program, which is funded by the U.S. Department of Energy at Pacific Northwest National Laboratory, to understand the value of, understand the theory behind, and simulate the behaviors of transactive energy systems. This report summarizes recent advances made by this program. The main capability advances include a more comprehensive valuation model, including recommended documentation that should make valuation studies of all sorts more transparent, definition of economic metrics with which transactive mechanisms can be evaluated, and multiple improvements to the time-simulation environment that is being used to evaluate transactive scenarios.

    Full Text Available This study on trade enhancement Characteristics of sweet (dessert banana fruit and estimation of transaction costs was conducted in Okigwe Metropolis of Imo State, Nigeria. Stratified random sampling technique was adopted in selecting 80 respondents comprising 40 dessert banana traders (panelists and 40 dessert banana consumers. Monthly trade data was collected from the respondents using pretested semi-structured questionnaire during dry season (November-April and rain season (May-October for the year 2012. Data collected were subjected to descriptive statistical analysis; with transaction costs estimated as ex ante and ex post components. Hedonic pricing regression model was used in determining buyer socioeconomic/banana attributes that influenced willingness to pay price. Fruit characteristics that significantly enhanced trade of sweet banana in descending order were taste (3.83, fruit variety (3.57, and fruit skin colour (3.50. Other significant factors were level of ripeness (3.49, availability in off-season (3.46, fruit size (3.20 and cleanliness (3.20. Mean ex-ante transaction costs for sweet banana was N77, 800.00/trader and its mean ex-post transaction cost was N25,080.00/trader. We recommended that traders should take advantage of Global Mobile System (GSM to overcome information barriers on banana trading. Government and health institutions should intensify consumer safety education, and encourage horticultural unions to heighten postharvest monitoring of stored and displayed dessert banana fruits to enforce observance of ripening standards.

  2. Psychological Spacetime

    Directory of Open Access Journals (Sweden)

    Lucian Gideon Conway

    2016-11-01

    Full Text Available It has been an accepted scientific fact in physics for almost 100 years that time speeds up and slows down for an observer based on factors—such as motion and gravity—that affect space. Yet this fact, drawn from the theory of relativity, has not been widely integrated into the study of the psychology of time. The present article helps to fill in this gap between physics and psychology by reviewing evidence concerning what a psychological spacetime processor—one that accounted for the theory of relativity’s empirically validated predictions of the compensatory relationship between time and space—would look like. This model of the spacetime processor suggests that humans should have a psychological mechanism for slowing time down as motion speeds up, a prediction that already has widespread research support. We also discuss several novel hypotheses directly suggested by the spacetime model and a set of related speculations that emerge when considering spacetime (some of which have already received empirical support. Finally, we compare and contrast three very different potential reasons why we might have developed a spacetime processor in the first place. We conclude that the spacetime model shows promise for organizing existing data on time perception and generating novel hypotheses for researchers to pursue. Considering how humans might process spacetime helps reduce the existing gap between our understanding of physics and our understanding of human psychology.

    Political psychology is a dynamic field of research that offers a unique blend of approaches and methods in the social and cognitive sciences. Political psychologists explore the interactions between macrolevel political structures and microlevel factors such as decision-making processes, motivations, and perceptions. In this article, we provide a broad overview of the field, beginning with a brief history of political psychology research and a summary of the primary methodological approaches in the field. We then give a more detailed account of research on ideology and social justice, two topics experiencing a resurgence of interest in current political psychology. Finally, we cover research on political persuasion and voting behavior. By summarizing these major areas of political psychology research, we hope to highlight the wide variety of theoretical and methodological approaches of cognitive scientists working at the intersection of psychology and political science.

  4. MOOD PROFILING DURING OLYMPIC QUALIFYING JUDO COMPETITION: A CASE STUDY TESTING TRANSACTIONAL RELATIONSHIPS

    Directory of Open Access Journals (Sweden)

    Matthew J. Stevens

    2006-07-01

    Full Text Available This case study investigated relationships between personality, mood states changes, coping strategies, self-set goals, and self-efficacy in an elite judo player. A transactional perspective of psychological responses over time was used to guide data analysis. The ambient mood is proposed to contribute to the interpretation of, and reaction to, events during competition, which lead to subsequent emotional responses. A male international Judo player completed a number of self-report measures before and during a 4-contest tournament. Measures included the EPQ, MCOPE, Brunel Mood Scale, self-set goals, and self-efficacy for goal attainment. State measures were completed after every contest. Results indicated high scores of self-efficacy to achieve performance goals and outcome goals. Pre-competition mood results indicated high scores on the Vigor and Anger subscales with moderate scores for Tension, and zero scores for Depressed mood, a mood profile that remained relatively stable after winning his first two contests. After losing his third contest, he reported symptoms of Depressed mood and indicated using self-blame as coping strategy during the contest. Before the fourth contest, he coped by using planning and increasing effort. These coping strategies were associated with reductions in Depressed mood and increases in Vigor. After finding out his next contest was against a former World Championship bronze medalist, self-set goals became performance and process with no outcome goal. On losing this contest, scores on the Anger and Depression subscales increased sharply, Fatigue scores increased slightly and Tension and Vigor reduced. Self-blame was used as a coping strategy when experiencing unpleasant emotions. Findings suggest that self-blame was associated with negative psychological states comprising depressed mood. Increasing effort and planning were associated with positive psychological states. Collectively, findings emphasize the value of

  6. Foreign exchange transaction exposure of enterprises in Serbia

    Directory of Open Access Journals (Sweden)

    Bogićević Jasmina

    2016-01-01

    Full Text Available Enterprises involved in international business face transaction exposure to foreign exchange risk. This type of exposure occurs when an enterprise trades, borrows, or lеnds in foreign currency. Transaction exposure has a direct effect on an enterprise’s financial position and profitability. It is one of the three forms of exposure to exchange rate fluctuations, the other two being translation exposure and operating exposure. The aim of this paper is to assess the transaction exposure of enterprises in Serbia operating internationally. In addition to identifying and measuring transaction exposure, this paper explores the practical importance that enterprises in Serbia attach to management of this type of foreign exchange risk. We do not find significant differences between domestic and foreign enterprises in their choice of the type of foreign exchange risk exposure to manage. Although transaction exposure is the most managed type of foreign exchange risk, research has shown that, compared to foreign businesses, Serbian enterprises do not use sufficient protective measures to minimize the negative impact of this type of exposure on their cash flows and profitability. We expected that there would be a statistically significant dependence between the volume of enterprises’ foreign currency transactions and the level of applied transaction exposure management practices. However, the results of our research, based on a sample of enterprises in Serbia operating internationally, show that transaction exposure management practices can be influenced by factors other than the level of an enterprise’s foreign currency transactions, such as the enterprise’s country of origin.

    2017-01-01

    For the purpose of providing excellent patient care, residents need to be strong, effective leaders. The lack of clinical leadership is alarming given the detrimental effects on patient safety. The objective of the study was to assess whether a leadership training addressing transactional and transformational leadership enhances leadership skills in residents. A volunteer sample of 57 residents from postgraduate year one to four was recruited across a range of medical specialties. The residents took part in an interventional controlled trial. The four-week IMPACT leadership training provided specific strategies for leadership in the clinical environment, addressing transactional (e.g. active control, contingent reward) and transformational leadership skills (e.g. appreciation, inspirational motivation). Transactional and transformational leadership skill performance was rated (1) on the Performance Scale by an external evaluator blinded to the study design and (2) self-assessed transformational and transactional leadership skills. Both measures contained items of the Multifactor Leadership Questionnaire, with higher scores indicating greater leadership skills. Both scores were significantly different between the IMPACT group and the control group. In the IMPACT group, the Performance Scale increased 15% in transactional leadership skill performance (2.10 to 2.86) (intervention effect, 0.76; 95% CI, 0.40 to 1.13; p leadership skill performance (2.26 to 2.94) (intervention effect, 0.68; 95% CI, 0.27 to 1.09; p skills revealed a 4% increase (3.83 to 4.03) (intervention effect, 0.20; 95% CI, 0.08 to 0.33; p leadership skills (3.54 to 3.86) (intervention effect, 0.31; 95% CI, 0.02 to 0.40; pleadership framework for graduate leadership training.

    Full Text Available Personalised, location-related and differentiated services in the mobile digitaleconomy create a demand for suitable pricing models. In the case of disaggregated“microservices” (e.g., small digitalized information or service units, as well as for theacquisition of low-value physical goods, the deployment of micropayments seemsappropriate.This paper analyzes the economic efficiency of marginal transaction amounts in the mcommercearea by applying the theoretical approach of transaction cost economics. Forthis purpose, a separation of technical and cognitive transaction costs is applied. Theinfluence of selected determinants such as specifity, uncertainty and bounded rationality ontransaction costs in mobile commerce micropayments is analyzed. The result is a morelikely application of micropayments for physical goods such as beverages or parking ticketsthan for digital goods and services, given the theoretical assumptions of the model. Inaddition, indicators for a significant above-zero lower limit of transaction amounts inmobile commerce are presented.

    . Hence, both the absolute productivity measures and, more importantly, the productivity ranking will be distorted. A major driver of transaction costs is poor access to information and contract enforcement assistance. Social networks often catalyse information exchange as well as generate trust...... and support. Hence, we use measures of a firm’s access to social networks as a proxy for the transaction costs the firm faces. We develop a microeconomic production model that takes into account transaction costs and networks. Using a data set of 384 Polish farms, we empirically estimate this model...... and compare different parametric, semiparametric, and nonparametric model specifications. Our results generally support our hypothesis. Especially, large trading networks and dense household networks have a positive influence on a farm’s productivity.

    2013-05-01

    Full Text Available The Bitcoin network of decentralized payment transactions has attracted a lot of attention from both Internet users and researchers in recent years. Bitcoin utilizes a peer-to-peer network to issue anonymous payment transactions between different users. In the currently used Bitcoin clients, the full transaction history is available at each node of the network to prevent double spending without the need for a central authority, forming a valuable source for empirical research on network structure, network dynamics, and the implied anonymity challenges, as well as guidance on the future evolution of complex payment systems. We found dynamical effects of which some increase anonymity while others decrease it. Most importantly, several parameters of the Bitcoin transaction graph seem to have become stationary over the last 12–18 months. We discuss the implications.

  5. Six Methods of Transaction Visualization in Virtual Environments

    2002-06-01

    Many governmental and corporate organizations are interested in tracking materials and/or information through a network. Often, as in the case of the U.S. Customs Service, the traffic is recorded as transactions through a large number of checkpoints with a correspondingly complex network. These networks will contain large numbers of uninteresting transactions that act as noise to conceal the chains of transactions of interest, such as drug trafficking. We are interested in finding significant paths in transaction data containing high noise levels, which tend to make traditional graph visualization methods complex and hard to understand. This paper covers the evolution of a series of graphing methods designed to assist in this search for paths-from 1-D to 2-D to 3-D and beyond.

    In FY13, Pacific Northwest National Laboratory (PNNL) with funding from the Department of Energy’s (DOE’s) Building Technologies Office (BTO) designed, prototyped and tested a transactional network platform. The platform is intended to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). Initially, in FY13, the concept demonstrated transactions between packaged rooftop units (RTUs) and the electric grid using applications or “agents” that reside on the platform, on the equipment, on local building controller or in the Cloud. This document describes the core of the transactional network platform, the Volttron Lite™ software and associated services hosted on the platform. Future enhancements are also discussed. The appendix of the document provides examples of how to use the various services hosted on the platform.

    2011-01-01

    This study examined psychological empowerment and organizational identification as outcomes of occupational context and predictors of occupational safety performance. In this study, 171 hospital employees from 17 units and 21 occupations completed surveys measuring psychological empowerment, organizational identification, and supervisor safety practices. They also completed measures of 2 dimensions of safety performance: use of personal protective equipment and safety participation. These data were merged with Occupational Information Network (O*NET) context ratings of occupational hazards and physical demands. Results indicated that occupational hazards were negatively related to individual-level psychological empowerment and organizational identification, which were in turn positively related to safety participation. Psychological empowerment and organizational identification also interacted with perceptions of supervisor safety actions in the prediction of personal protective equipment use. Results have implications for organizational safety performance and point to the role of occupational context in psychological empowerment and the extent to which employees participate in the safety of their worksite.

    2014-10-01

    In this short-term longitudinal study, transactional links between teacher-child relationships and behavioral adjustment were investigated in a sample of preschool boys (N=175) at risk for developing externalizing problems. Teachers (N=175) reported about the quality of the teacher-child relationship (i.e., Closeness, Conflict, and Dependency) and about children's behavioral adjustment (i.e., Externalizing Behavior, Internalizing Behavior, and Prosocial Behavior) at three occasions within one school year. Cross-lagged path-analytic models showed positive bidirectional associations between Conflict and both Externalizing and Internalizing Behavior from Time 1 to Time 2, but not from Time 2 to Time 3. In addition, there was a transactional sequence with more Conflict at Time 1 leading to less Prosocial Behavior at Time 2 which, in turn, predicted more Conflict at Time 3. Closeness was reciprocally and positively related to Prosocial Behavior over time, and was positively and unidirectionally predicted by Internalizing Behavior. Dependency showed positive reciprocal links with Internalizing Behavior over time, and negatively and unidirectionally predicted Prosocial Behavior. These findings suggest that interventions may be most effective if they adjust their focus and strategy depending on children's specific behavioral and relational needs.

  19. Third sector organizations in rural development: a transaction cost perspective

    Directory of Open Access Journals (Sweden)

    V. VALENTINOV

    2008-12-01

    Full Text Available In many parts of the world, rural development is supported by third sector organizations, such as nongovernmental organizations, farmer associations, and cooperatives. This essay develops a transaction cost explanation of these organizations’ role in rural areas. Since the traditional transaction cost theory is concerned with the choice of governance mechanisms within the for-profit sector, this essay adopts an alternative conceptualization of the notion of transaction cost by building on the theory of the division of labor. This theory regards transaction cost as a constraint on the division of labor causing the replacement of exchange with self-sufficiency. The proposed transaction cost explanation of rural third sector organizations consists of two arguments: 1 third sector organizations embody partial reliance on self-sufficiency; and 2 rural areas exhibit rurality-specific transaction cost acting as a constraint on the division of labor and thus creating a niche for third sector organizations. The essay concludes with suggesting a research program on developing an economic theory of the rural third sector.;

  20. Anonymous publication of sensitive transactional data

    KAUST Repository

    Ghinita, Gabriel

    2011-02-01

    Existing research on privacy-preserving data publishing focuses on relational data: in this context, the objective is to enforce privacy-preserving paradigms, such as k-anonymity and ℓ-diversity, while minimizing the information loss incurred in the anonymizing process (i.e., maximize data utility). Existing techniques work well for fixed-schema data, with low dimensionality. Nevertheless, certain applications require privacy-preserving publishing of transactional data (or basket data), which involve hundreds or even thousands of dimensions, rendering existing methods unusable. We propose two categories of novel anonymization methods for sparse high-dimensional data. The first category is based on approximate nearest-neighbor (NN) search in high-dimensional spaces, which is efficiently performed through locality-sensitive hashing (LSH). In the second category, we propose two data transformations that capture the correlation in the underlying data: 1) reduction to a band matrix and 2) Gray encoding-based sorting. These representations facilitate the formation of anonymized groups with low information loss, through an efficient linear-time heuristic. We show experimentally, using real-life data sets, that all our methods clearly outperform existing state of the art. Among the proposed techniques, NN-search yields superior data utility compared to the band matrix transformation, but incurs higher computational overhead. The data transformation based on Gray code sorting performs best in terms of both data utility and execution time. © 2006 IEEE.

  5. Transactional Mechanism of Territorial Administration: Conceptualisation and Systematization of Elements

    Directory of Open Access Journals (Sweden)

    Elena Аleksandrovna Petrova

    2016-12-01

    Full Text Available The concept of transaction expenses developed by R. Coase allows to consider functioning of economy and its agents from the information viewpoint. This viewpoint implies that information exchange between agents and the urge to overcome information incompleteness start playing the crucial role. Transaction expenses are information exchange costs for the purpose of elimination (reduction of its incompleteness and the related uncertainty. R. Coase showed that creation and the size of firms are closely connected with the urge to minimize transaction expenses. Traditionally transaction expenses are associated with functioning of firms, however, the state actively participates in economy, for example, through formation of tax policy. Besides, financing of the public benefits takes place on the basis of collective decisions. But collective character of the decision causes interest, though smaller in comparison with the private choice, in the maximum efficiency of the decision. It is ensured by two factors: firstly, the position of an individual is not of great importance at collective decision-making; secondly, an individual is responsible for a small part of benefits and expenses which are formed in the course of decision implementation. The article deals with the concept of transaction costs, and systematically occurring types of transaction costs in the following groups: search information costы, the cost of negotiating, measuring costs, the costs of specification and protection of property rights, the costs of opportunistic behavior, the cost of “politicizing”, the costs of collective decisionmaking, influence costs. The authors propose a model of transaction mechanism of territorial administration, which includes the following elements: economic entities; a goal determined by system of indicators; methods; instruments; channels; forms of target use; landmark feedback on the system; subject to the experience stage of modernization; criteria

  8. TRANSACTIONAL LEADER IN ROMANIAN PRIVATE BANKING SYSTEM

    Directory of Open Access Journals (Sweden)

    Lucian Ciprian CRIȘAN

    2016-05-01

    Full Text Available From a managerial point of view, all the media means of professional communication, socialization and interaction emphasize entrepreneurial success stories. One of the modern concerns of all current researchers is to underline the place and role of leaders in the institutional framework. The leadership is perceived as a support pillar in maintaining any business. The analysis of this phenomenon is extremely extensive, starting with the culture of a company, the purpose of its existence and comprises aspects concerning the employees motivation and the degree of identifying themselves with the organizational objective. A constant concern in analyzing this phenomenon is retaining the employees and encouraging them to bring added value to the organization where they perform their daily activities. Nevertheless, the Romanian banking system in Timişoara seems to display a strong resistance towards change. The leadership of this industry is comprised of people with great managerial abilities. The transactional method, manifested by the leader in the Romanian private banking system in Timişoara, seems to be the main phenomenon at the basis of their daily activity. The manager – leader hypothesis is slowly taking shape. Due to the resistance to change, generated by the educational model, from a managerial point of view, the balance is strongly tilting towards the managerial traits at the expense of the leadership ones. We are still at the stage where the tolerance towards liberty, uncertainty, are some of the traits of the leader in the Romanian private banking system in Timişoara, which are poorly identified at the management level of this very important segment of activity.

    This study develops an integrative model of safety management based on social cognitive theory and the total safety culture triadic framework. The purpose of the model is to reveal the causal linkages between a hazardous environment, safety climate, and individual safety behaviors. Based on primary survey data from 209 front-line workers in one of the largest state-owned coal mining corporations in China, the model is tested using structural equation modeling techniques. An employee's perception of a hazardous environment is found to have a statistically significant impact on employee safety behaviors through a psychological process mediated by the perception of management commitment to safety and individual beliefs about safety. The integrative model developed here leads to a comprehensive solution that takes into consideration the environmental, organizational and employees' psychological and behavioral aspects of safety management.

    2005-05-31

    Adolescence is a transitional period dominated by puberty modifications. These modifications must come with a psychological work leading towards increased self containing from parents and also towards the choice of an own life orientation. In order to do so, adolescent must satisfy his needs to be able to change. This process will not run smoothly. The troubled adolescent will express himself with groans or acting out more than with words. This modus operandi is typical of that age. The general practitioner will be in the front line in being attentive to the adolescent and his parents needs.

    2016-01-01

    Findings in behavioral science, including psychology, have influenced policies and reforms in many nations. Choice architecture can affect outcomes even if material incentives are not involved. In some contexts, default rules, simplification, and social norms have had even larger effects than significant economic incentives. Psychological research is helping to inform initiatives in savings, finance, highway safety, consumer protection, energy, climate change, obesity, education, poverty, development, crime, corruption, health, and the environment. No nation has yet created a council of psychological advisers, but the role of behavioral research in policy domains is likely to grow in the coming years, especially in light of the mounting interest in promoting ease and simplification ("navigability"); in increasing effectiveness, economic growth, and competitiveness; and in providing low-cost, choice-preserving approaches.

  13. The logic of transaction cost economics in health care organization theory.

    Stiles, R A; Mick, S S; Wise, C G

    2001-01-01

    Health care is, at its core, comprised of complex sequences of transactions among patients, providers, and other stakeholders; these transactions occur in markets as well as within systems and organizations. Health care transactions serve one of two functions: the production of care (i.e., the laying on of hands) or the coordination of that care (i.e., scheduling, logistics). Because coordinating transactions is integral to care delivery, it is imperative that they are executed smoothly and efficiently. Transaction cost economics (TCE) is a conceptual framework for analyzing health care transactions and quantifying their impact on health care structures (organizational forms), processes, and outcomes.

    2017-09-01

    The reciprocal transactions that shape early parent-child relationships are influenced by contextual stress, such as family conflict. Although family conflict is a salient stressor to the family system, few studies have considered how parent-child transactions vary according to exposure to family conflict. The present study examined how family conflict alters early parent-child behavioral transactions. We utilized three waves of data from a multisite longitudinal study of low-income families (N = 2, 876), child age 14 months, 24 months, and 36 months, to identify behavioral transactions of positive and negative maternal (supportiveness, negative regard) and child (engagement, negativity) behaviors. Results indicated that family conflict at 14 months diminished the positive association between maternal supportiveness and child engagement, and amplified the inverse association between maternal negativity and child engagement. Family conflict at 14 months also was associated with increased stability of child negativity and subsequent increased maternal negative regard at 36 months, in part via increases in 24-month child negativity. In sum, family conflict occurring early in childhood predicted and moderated behavioral transactions between young children and their mothers. © 2017 Michigan Association for Infant Mental Health.

  15. Money laundering: correlation between risk assessment and suspicious transactions

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The risk assessment system was introduced in the Republic of Croatia in 2009, as a result of harmonization with international standards, especially the Directive 2005/60/EC on the prevention of the use of the financial system for the purpose of money laundering and terrorist financing. Risk assessment is an extensive concept which requires not only a legislative framework, but also the application of numerous criteria for its effective implementation in practice. Among these criteria are suspicious transactions, closely related to the assessment of the customer, transaction, product or service.The undeniable contribution of suspicious transactions to the quality of the risk assessment system will be confirmed by a statistical analysis of a number of West and East European countries. A combination of strict, but sufficiently flexible legal provisions governing the system for prevention of money laundering and terrorist financing and a statistical analysis of reported suspicious transactions will lead to conclusions that either support or represent criticism of the efficiency of application of the risk assessment system in practice.The aforementioned statistical analysis will show whether suspicious transactions are a reliable criterion for the risk assessment analysis, and whether they can be considered the only such criterion. There is a possibility that the findings of the analysis will be contradictory to those of some international studies.

    2016-01-01

    Recently, the Bitcoin-underlying blockchain technology gained prominence as a solution that offers the realization of distributed trust-free systems, where economic transactions are guaranteed by the underlying blockchain. We are still at an early stage and thus require a deeper understanding...... of how the blockchain potentials can be realized, and what are the opportunities and challenges in so doing. Following a design science approach, we developed a proof of concept prototype that has the potential to replace a trust-based coffee shop payment solution that is based on an analogue, pre......-paid punch card solution. The demonstrator provides a starting point to evaluate the strengths and weaknesses of the blockchain technology when replacing a trust-based by a trust-free transaction system. We conclude that the secure and trust-free blockchain-based transaction has the potential to change many...

  17. Ontological leveling and elicitation for complex industrial transactions

    Energy Technology Data Exchange (ETDEWEB)

    Phillips, L.R.; Goldsmith, S.Y.; Spires, S.V.

    1998-11-01

    The authors present an agent-oriented mechanism that uses a central ontology as a means to conduct complex distributed transactions. This is done by instantiating a template object motivated solely by the ontology, then automatically and explicitly linking each temple element to an independently constructed interface component. Validation information is attached directly to the links so that the agent need not know a priori the semantics of data validity, merely how to execute a general validation process to satisfy the conditions given in the link. Ontological leveling is critical: all terms presented to informants must be semantically coherent within the central ontology. To illustrate this approach in an industrial setting, they discuss an existing implementation that conducted international commercial transactions on the World-Wide Web. Agents operating within a federated architecture construct, populate by Web-based elicitation, and manipulate a distributed composite transaction object to effect transport of goods over the US/Mexico border.

  18. Leadership in Academic Health Centers: Transactional and Transformational Leadership.

    Smith, Patrick O

    2015-12-01

    Leadership is a crucial component to the success of academic health science centers (AHCs) within the shifting U.S. healthcare environment. Leadership talent acquisition and development within AHCs is immature and approaches to leadership and its evolution will be inevitable to refine operations to accomplish the critical missions of clinical service delivery, the medical education continuum, and innovations toward discovery. To reach higher organizational outcomes in AHCs requires a reflection on what leadership approaches are in place and how they can better support these missions. Transactional leadership approaches are traditionally used in AHCs and this commentary suggests that movement toward a transformational approach is a performance improvement opportunity for AHC leaders. This commentary describes the transactional and transformational approaches, how they complement each other, and how to access the transformational approach. Drawing on behavioral sciences, suggestions are made on how a transactional leader can change her cognitions to align with the four dimensions of the transformational leadership approach.

    2012-12-01

    Full Text Available Previous studies have shown that product market competition has an important effect on corporate strategies and internal governance mechanisms. Using a sample of China’s listed firms from 2004 to 2009, we explore the relationship between product market competition and normal related party transactions and find a significant positive relationship. In addition, we investigate the substitutive effect of product market competition and the cash flow rights owned by ultimate controlling shareholders on the extent of normal related party transactions. In particular, our results suggest a positive relationship between the ultimate controlling shareholders’ cash flow rights and normal related party transactions that is strongest in noncompetitive industries and weakens as product market competition increases.

  20. Transaction Costs: Prosecuting child trafficking for illegal adoption in Russia

    Directory of Open Access Journals (Sweden)

    Lauren A McCarthy

    2016-05-01

    Full Text Available As primary implementers of laws on human trafficking, law enforcement helps construct how these laws are understood and applied. This article examines how this process has unfolded in Russia by looking at the phenomenon of and debates surrounding child trafficking for illegal adoption. It argues that pre-existing experience with trafficking laws and cultural narratives surrounding adoption have led law enforcement to focus on uncovering evidence of monetary transactions rather than exploitation when prosecuting trafficking cases. This construction of the meaning of trafficking comes with important trade-offs. While the emphasis on transactions helps law enforcement to be successful at prosecuting cases involving selling children for illegal adoption, a focus on transactions rather than exploitation results in a de facto prosecution policy that ignores the many forms of exploitation that occur in other trafficking cases.

  1. A Method for Visualizing Transaction Logs of a Faceted OPAC

    Directory of Open Access Journals (Sweden)

    Xi Niu

    2010-12-01

    Full Text Available The authors introduce a method for visualizing user transaction logs from a library catalog application. Simple visualization supporting intuitive or qualitative analysis to quickly make sense of complicated patterns can be a useful supplement or alternative to more common quantitative analysis. To this end, a visual flowchart is created illustrating an individual user session. This visualization can be used to qualitatively grasp user behavior within the application, possibly as an aid to identifying patterns or clusters of use. These flowcharts are created by automatically pre-processing apache transaction logs into an XML representation of meaningful user actions, which are then converted via JavaScript in a web browser to HTML table based flowcharts. The particular toolkit introduced is named Visualization for Understanding Transaction Logs (VUTL, and is available with an open source license. The toolkit has been prototyped with logs from the catalog applications of several academic and one public library.

  2. A Coloured Petri Net Analysis of the Transaction Internet Protocol

    Science.gov (United States)

    Georgiadis, Christos K.; Kokkinidis, Ioannis; Pimenidis, Elias

    The Transaction Internet Protocol (TIP) aims to facilitate e-commerce by enforcing atomicity guarantees in transactions distributed between several autonomous transaction processing systems. In this work, the authors explore a holiday booking scenario in which a customer is protected by the TIP; in such a way as to prevent ending up with a hotel reservation without the requested flight reservation that is enclosed in the same holiday package. TIP defines an approach that makes the commit processing independent of the communication protocol used. There are a number of potential pitfalls that make it useful to provide a formal approach to reason about the behavioral properties of TIP. The authors propose a Colored Petri Net model that allows interactive simulation and verification of correctness properties within the CPN Tools modeling environment. The model can be used in the CPN Tools environment for model checking tasks.

  3. Personality and transformational and transactional leadership: a meta-analysis.

    Science.gov (United States)

    Bono, Joyce E; Judge, Timothy A

    2004-10-01

    This study was a meta-analysis of the relationship between personality and ratings of transformational and transactional leadership behaviors. Using the 5-factor model of personality as an organizing framework, the authors accumulated 384 correlations from 26 independent studies. Personality traits were related to 3 dimensions of transformational leadership--idealized influence-inspirational motivation (charisma), intellectual stimulation, and individualized consideration--and 3 dimensions of transactional leadership--contingent reward, management by exception-active, and passive leadership. Extraversion was the strongest and most consistent correlate of transformational leadership. Although results provided some support for the dispositional basis of transformational leadership--especially with respect to the charisma dimension--generally, weak associations suggested the importance of future research to focus on both narrower personality traits and nondispositional determinants of transformational and transactional leadership.

    Corrigan, P W; Garman, A N

    1999-08-01

    Many treatments for persons with severe mental illness are provided by mental health teams. Team members work better when led by effective leaders. Research conducted by organizational psychologists, and validated on mental health teams, have identified a variety of skills that are useful for these leaders. Bass (1990, 1997) identified two sets of especially important skills related to transformational and transactional leadership. Leaders using transformational skills help team members to view their work from more elevated perspectives and develop innovative ways to deal with work-related problems. Skills related to transformational leadership promote inspiration, intellectual stimulation, individual consideration, participative decision making, and elective delegation. Mental health and rehabilitation teams must not only develop creative and innovative programs, they must maintain them over time as a series of leader-team member transactions. Transactional leadership skills include goal-setting, feedback, and reinforcement strategies which help team members maintain effective programs.

  5. COULD SOCIOECONOMIC METABOLISM BE MOLDED BY TRANSACTION COSTS?

    Directory of Open Access Journals (Sweden)

    RALUCA I. IORGULESCU

    2017-06-01

    Full Text Available Two key issues that shape the economic development and growth of a country are the independence and effectiveness of the judicial system and the level of bureaucracy. The theory of transaction costs, developed, among others, by Douglass C. North, explores both. Increasing the independence and effectiveness of the judicial system reduces corruption and protects private property and economic freedom while reducing bureaucracy is absolutely necessary to increase a country's competitiveness by lowering the cost and increasing the speed of transactions. This paper introduces the transaction costs approach, the concept of ‘socioeconomic/societal metabolism’ and takes advantage of the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM to examine how the ‘socioeconomic/societal metabolism’ could be impacted.

    2007-01-01

    Fog doubles the risk of accidents and modifies driving behaviour in a way that leads to greater risk-taking. Traffic studies indicate that most drivers adopt excessive speeds and insufficient headways in foggy conditions. Yet our understanding of the psychological processes underlying this common but unsuitable behaviour, and the effectiveness of road safety measures, remain limited. Two main hypotheses have been put forward. The first one, stemming from social psychology, evokes a deteriorat...

  7. Polycultural psychology.

    Science.gov (United States)

    Morris, Michael W; Chiu, Chi-yue; Liu, Zhi

    2015-01-03

    We review limitations of the traditional paradigm for cultural research and propose an alternative framework, polyculturalism. Polyculturalism assumes that individuals' relationships to cultures are not categorical but rather are partial and plural; it also assumes that cultural traditions are not independent, sui generis lineages but rather are interacting systems. Individuals take influences from multiple cultures and thereby become conduits through which cultures can affect each other. Past literatures on the influence of multiple cultural identities and cultural knowledge legacies can be better understood within a polyculturalist rubric. Likewise, the concept elucidates how cultures are changed by contact with other cultures, enabling richer psychological theories of intercultural influence. Different scientific paradigms about culture imply different ideologies and policies; polyculturalism's implied policy of interculturalism provides a valuable complement to the traditional policy frames of multiculturalism and colorblindness.

  8. FCJ-149 Affect and Care in Intimate Transactions

    Directory of Open Access Journals (Sweden)

    Lone Bertelsen

    2012-01-01

    Full Text Available This article considers the ‘co-affective’ power of the new media artwork Intimate Transactions. This co-affective power operates at the ‘trans-subjective’ level of experience. In order to explore this level of experience the article draws on the work of Brian Massumi, Bracha Ettinger and Felix Guattari amongst others. For these thinkers the ‘trans-subjective’ level of experience, precisely because it is ‘co-affective’, holds ethical potential. The article argues for the importance of tending to ‘co-affective’ level of experience – both in designing “interactive” art, such as Intimate Transactions, and in life more generally.

    DEFF Research Database (Denmark)

    2001-01-01

    Under the assumption of purely additive transaction costs in exchange, the literature on money has a standard example of direct exchange dominating indirect (monetary) exchange. From here it is frequently concluded that subadditive costs (e.g. search costs) must be examined in order to explain...... money. In contrast, this paper presents an additive transaction costs model in which the mere absence of double coincidences of wants suffices to motivate monetary exchange. Furthermore it is found that not all commodity moneys, that are collectively desirable, qualify for the core, but that all fiat...... moneys, that are collectively desirable, will be elements of the core.

    This paper reexamines the hypothesis of Dean S. Dutton and William P. Gramm, and Edi Karni that the wage rate influences the demand for money as a proxy for the value of transactions time. It develops "value of time" transactions models, which yield demand for money equations that have a real wage rate argument, and compares it to a "non value of time" alternative that does not. The author finds that the "value of time" models perform well and that the "value of time" effect is empirically si...

    2003-04-01

    How do leadership ratings collected from units operating under stable conditions predict subsequent performance of those units operating under high stress and uncertainty? To examine this question, the authors calculated the predictive relationships for the transformational and transactional leadership of 72 light infantry rifle platoon leaders for ratings of unit potency, cohesion, and performance for U.S. Army platoons participating in combat simulation exercises. Both transformational and transactional contingent reward leadership ratings of platoon leaders and sergeants positively predicted unit performance. The relationship of platoon leadership to performance was partially mediated through the unit's level of potency and cohesion. Implications, limitations, and future directions for leadership research are discussed.

  18. The Value Added Tax Implications of Illegal Transactions

    Directory of Open Access Journals (Sweden)

    SP van Zyl

    2011-01-01

    Full Text Available In the case of MP Finance Group CC (In Liquidation v CSARS the High Court of Appeal ruled that income "received by" a taxpayer from illegal gains will be taxable in the hands of the taxpayer. This article explores whether or not the decision in the MP Finance-case (and preceding cases on the taxation of illegal receipts can be applied to determine if illegal transactions are subject to VAT and moreover if a trader in illegal goods and services should register as a VAT vendor. Although strictly speaking no analogy can be drawn between the charging provisions for income tax and VAT, it is clear that in the determination of the taxability of illegal income, the courts applied the principle of tax neutrality. In terms of the principle of tax neutrality, taxes are not concerned with the legality or illegality of a transaction, but rather with whether the transaction complies with the requirements for it to be taxed or not. That said, the European Court of Justice has a different approach in applying this principle. According to the European Court of Justice where the intrinsic nature of the goods excludes it from the commercial arena (like narcotic drugs it should not be subject to VAT, but where the goods compete with a legal market it must be subject to VAT. Charging VAT on illegal transactions might give the impression that government benefits from criminal activities. However, if illegal transactions are not subject to VAT the trader in illegal goods will benefit as his products will be 14% cheaper than his rival’s. Is this necessarily a moral dilemma? In conclusion three arguments can be deduced on the question if illegal transactions should be subject to VAT:1. Illegal transactions should not be taxed at all. Illegal goods or services fall outside the sphere of the application of the charging provision in section 7(1 of the VAT Act. Moreover, taxing illegal transactions lends a quasi-validity to the contract and gives the impression that

    Full Text Available The overview of evolution of market infrastructure concepts is provided, the first concepts of institutional infrastructure are revealed in the paper. Evolutionarily developed narrowing of essence of infrastructure in connection with the priority analysis of its physical (material and technological components is proved. It ignores the fact that transactional resources, being drivers (driving forces of economic systems evolution, in turn evolve, becoming harder and harder, combining increase in efficiency of the elements and strengthening of heterogeneity and discrepancy of their structure. Transactional evolution of economy in general and evolution of separate transactional resources of production are the perspective directions of the special analysis. Transactional infrastructure is considered as the integrated complex of institutional, organizational (relational and information infrastructures. The problems of the first concepts of transactional infrastructure connected with difficulties of differentiation of its subsystems always operating jointly are revealed. Prospect of transition from the isolated analysis of separate resources of transactional type (institutes, organizations, information, social capital, trust, etc. to studying corresponding specific software infrastructures and to the system analysis of integrated transactional infrastructure of economy are argued. The transactional sector (as set of the specialized industries and the appropriate collective and individual subjects providing with resources market transaction is offered to be considered as transactional structure of economy. Transactional infrastructure is treated as critically significant factor of economic evolution which in the conditions of post-industrial type of economy gradually purchases transactional nature.

  1. Psychology's Renaissance.

    Science.gov (United States)

    Nelson, Leif D; Simmons, Joseph; Simonsohn, Uri

    2018-01-04

    In 2010-2012, a few largely coincidental events led experimental psychologists to realize that their approach to collecting, analyzing, and reporting data made it too easy to publish false-positive findings. This sparked a period of methodological reflection that we review here and call Psychology's Renaissance. We begin by describing how psychologists' concerns with publication bias shifted from worrying about file-drawered studies to worrying about p-hacked analyses. We then review the methodological changes that psychologists have proposed and, in some cases, embraced. In describing how the renaissance has unfolded, we attempt to describe different points of view fairly but not neutrally, so as to identify the most promising paths forward. In so doing, we champion disclosure and preregistration, express skepticism about most statistical solutions to publication bias, take positions on the analysis and interpretation of replication failures, and contend that meta-analytical thinking increases the prevalence of false positives. Our general thesis is that the scientific practices of experimental psychologists have improved dramatically.

  16. Financial Transaction Tax: Determination of Economic Impact Under DSGE Model

    Directory of Open Access Journals (Sweden)

    Veronika Solilová

    2015-01-01

    Full Text Available The discussion about the possible taxation of the financial sector has started in the European Union as a result of the financial crisis which has spread to the Europe from the United States in 2008 and consequently of the massive financial interventions by governments made in favour of the financial sector. On 14 February 2013, after rejection of the draft of the directive introducing a common system of financial transaction tax in 2011, the European Commission introduced the financial transaction tax through enhanced cooperation. The aim of the paper is to research economic impact of financial transaction tax on EU (EU27 or EU11 with respect to the DSGE model which was used for the determination of impacts. Based on our analysis the DSGE model can be considered as underestimated in case of the impact on economic growth and an overestimated in case of the revenue collection. Particularly, the overall impact of the financial transaction tax considering cascade effects of securities (tax rate 2.2% and derivatives (tax rate 0.2% is ranged between −4.752 and 1.472 percent points of GDP. And further, is assumed that the relocation effects of business/trade can be in average 40% causes a decline of expected tax revenues in the amount of 13bn EUR. Thus, at a time of fragile economic growth across the EU and the increased risk of recession in Europe, the introduction of the FTT should be undesirable.

    Full Text Available Intimate Transactions is a networked interactive installation for two participants located in different geographical locations. During a 30-minute, one-on-one session they individually and collaboratively explore a range of virtual, interactive environments mediated by digital image, sound and haptic feedback. This major work evolved from a single site, non-networked version to a multi-site, server-driven artwork that operates in mixed online/offline modes. In 2005, the work was awarded an Honorary Mention in the Prix Ars Electronica and began an international tour of several high profile festivals and arts’ venues. Intimate Transactions is a product of the Transmute Collective (http://www.intimatetransactions.com.Intimate Transactions networked inter-relational design was inspired by a range of conditions, discourses and practices drawn from scientific and critical ecologies, new media and innovative performance that I collectively name ‘ecosophical praxis’. An inherent part of this approach involves the continual development of contextualizing questions, which in turn mould the work’s practice and presentation. This paper considers the issues and implications of applying this approach during the Intimate Transactions project. The concluding questions are relevant as a guiding method for othercreative practitioners similarly interested in eco-social and eco-political engagement.

    The Transactional Network Project is a multi-lab activity funded by the US Department of Energy?s Building Technologies Office. The project team included staff from Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory and Oak Ridge National Laboratory. The team designed, prototyped and tested a transactional network (TN) platform to support energy, operational and financial transactions between any networked entities (equipment, organizations, buildings, grid, etc.). PNNL was responsible for the development of the TN platform, with agents for this platform developed by each of the three labs. LBNL contributed applications to measure the whole-building electric load response to various changes in building operations, particularly energy efficiency improvements and demand response events. We also provide a demand response signaling agent and an agent for cost savings analysis. LBNL and PNNL demonstrated actual transactions between packaged rooftop units and the electric grid using the platform and selected agents. This document describes the agents and applications developed by the LBNL team, and associated tests of the applications.

  11. Capturing and using precise semantics for complex transactions

    Energy Technology Data Exchange (ETDEWEB)

    Phillips, L.R.; Goldsmith, S.Y.; Spires, S.V.

    1998-08-01

    In this paper the authors discuss the leveling process by which a business process ontology is formed in a distributed, multi-lingual, multi-stakeholder environment, with attention to realizing elicitation mechanisms that maintain registration of users` terms with the common ontology. Business processes are recognized from use-case analysis, specified in terms of the common ontology, and realized as operations on the components of a transaction: a temporally extended, complex, distributed object. A primary advantage of this approach is that users see private terminologies while the transaction object is specified in terms of the common ontology, and registration between the two is automatic and continuous. Ready realization of multiple interfaces to stakeholders, independently constructed validation and verification mechanisms, distributed data, and a standard elicitation mechanism and process are other advantages. The language formation process was used successfully during the development of the Border Trade Facilitation System, an agent-oriented mechanism that conducts international border-crossing transactions. In this implementation, agents operating within a federated architecture construct, populate, verify, certify, and manipulate a distributed composite transaction object to effect transport of goods over the US/Mexico border.

  13. Multi-period fuzzy mean-semi variance portfolio selection problem with transaction cost and minimum transaction lots using genetic algorithm

    Directory of Open Access Journals (Sweden)

    Mohammad Ali Barati

    2016-04-01

    Full Text Available Multi-period models of portfolio selection have been developed in the literature with respect to certain assumptions. In this study, for the first time, the portfolio selection problem has been modeled based on mean-semi variance with transaction cost and minimum transaction lots considering functional constraints and fuzzy parameters. Functional constraints such as transaction cost and minimum transaction lots were included. In addition, the returns on assets parameters were considered as trapezoidal fuzzy numbers. An efficient genetic algorithm (GA was designed, results were analyzed using numerical instances and sensitivity analysis were executed. In the numerical study, the problem was solved based on the presence or absence of each mode of constraints including transaction costs and minimum transaction lots. In addition, with the use of sensitivity analysis, the results of the model were presented with the variations of minimum expected rate of programming periods.

  14. Investigating the cognitive precursors of emotional response to cancer stress: re-testing Lazarus's transactional model.

    Science.gov (United States)

    Hulbert-Williams, N J; Morrison, V; Wilkinson, C; Neal, R D

    2013-02-01

    Lazarus's Transactional Model of stress and coping underwent significant theoretical development through the 1990s to better incorporate emotional reactions to stress with their appraisal components. Few studies have robustly explored the full model. This study aimed to do so within the context of a major life event: cancer diagnosis. A repeated measures design was used whereby data were collected using self-report questionnaire at baseline (soon after diagnosis), and 3- and 6-month follow-up. A total of 160 recently diagnosed cancer patients were recruited (mean time since diagnosis = 46 days). Their mean age was 64.2 years. Data on appraisals, core-relational themes, and emotions were collected. Data were analysed using both Spearman's correlation tests and multivariate regression modelling. Longitudinal analysis demonstrated weak correlation between change scores of theoretically associated components and some emotions correlated more strongly with cognitions contradicting theoretical expectations. Cross-sectional multivariate testing of the ability of cognitions to explain variance in emotion was largely theory inconsistent. Although data support the generic structure of the Transactional Model, they question the model specifics. Larger scale research is needed encompassing a wider range of emotions and using more complex statistical testing. WHAT IS ALREADY KNOWN ON THIS SUBJECT?: • Stress processes are transactional and coping outcome is informed by both cognitive appraisal of the stressor and the individual's emotional response (Lazarus & Folkman, 1984). • Lazarus (1999) made specific hypotheses about which particular stress appraisals would determine which emotional response, but only a small number of these relationships have been robustly investigated. • Previous empirical testing of this theory has been limited by design and statistical limitations. WHAT DOES THIS STUDY ADD?: • This study empirically investigates the cognitive precedents of a

  18. A transactional framework for pediatric rehabilitation: shifting the focus to situated contexts, transactional processes, and adaptive developmental outcomes.

    Science.gov (United States)

    King, Gillian; Imms, Christine; Stewart, Debra; Freeman, Matt; Nguyen, Tram

    2017-04-11

    A paradigm shift is taking place in pediatric rehabilitation research, practice, and policy - a shift towards the real-life contexts of clients rather than requiring clients to navigate the world of pediatric rehabilitation. This article proposes a conceptual framework to bring about a broader awareness of clients' lives and transactional processes of change over the life course. The framework draws attention to transactional processes by which individuals, situated in life contexts, change and adapt over the life course and, in turn, influence their contextual settings and broader environments. This framework is based on (a) basic tenets derived from foundational theories taking a life course perspective to change, and (b) transactional processes identified from relevant pediatric rehabilitation models that bring these foundational theories into the pediatric rehabilitation sphere. The framework identifies three types of transactional processes relevant to pediatric rehabilitation: facilitative, resiliency, and socialization processes. These processes describe how contexts and people mutually influence each other via opportunities and situated experiences, thus facilitating capacity, adaptation to adversity, and socialization to new roles and life transitions. The utility of the framework is considered for research, practice, service organizations, and policy. Implications for Rehabilitation The framework supports practitioners going beyond person and environment as separate entities, to provide services to the "situated person" in real-life contexts The framework shifts the focus from "body structures/functions" and "person in activity" to "person in changing and challenging life contexts" Working from a transactional perspective, practitioner-client conversations will change; practitioners will view client situations through a lens of opportunities and experiences, assess client experiences in real-life contexts, and strive to create context-based therapy

  19. VAET: A Visual Analytics Approach for E-Transactions Time-Series.

    Science.gov (United States)

    Xie, Cong; Chen, Wei; Huang, Xinxin; Hu, Yueqi; Barlowe, Scott; Yang, Jing

    2014-12-01

    Previous studies on E-transaction time-series have mainly focused on finding temporal trends of transaction behavior. Interesting transactions that are time-stamped and situation-relevant may easily be obscured in a large amount of information. This paper proposes a visual analytics system, Visual Analysis of E-transaction Time-Series (VAET), that allows the analysts to interactively explore large transaction datasets for insights about time-varying transactions. With a set of analyst-determined training samples, VAET automatically estimates the saliency of each transaction in a large time-series using a probabilistic decision tree learner. It provides an effective time-of-saliency (TOS) map where the analysts can explore a large number of transactions at different time granularities. Interesting transactions are further encoded with KnotLines, a compact visual representation that captures both the temporal variations and the contextual connection of transactions. The analysts can thus explore, select, and investigate knotlines of interest. A case study and user study with a real E-transactions dataset (26 million records) demonstrate the effectiveness of VAET.

    Carr, Christopher M

    2006-08-01

    This article has briefly highlighted the area of sport psychology as it relates to performance psychology skills (mental training), including a historical overview and current topics overview. The use of mental training skills may be of interest to the practicing physical medicine and rehabilitation professional in the treatment of his or her patients. It is important that the physical medicine professional recognize what sport or performance psychology represents within the paradigm of psychologic interventions. Referring to an individual based on his or her training (licensed psychologist versus mental training consultant) is essential for the appropriate management of psychologic issues related to performance. The issues related to the psychologic rehabilitation of the injured athlete are of importance to the medical staff; the overview of affective responses can assist in understanding the normal and adaptive responses of the injured athlete. Finally, a brief description of a psychologist's role within a sports medicine and rehabilitation practice is presented. The psychologic issues that are present in the world of sport and elite performance are numerous, and not all are mentioned in this article. Issues of eating disorders, substance abuse, and psychologic health with athletes should be further explored within the physical medicine and rehabilitation discipline as well as in the sports medicine discipline. The ever-evolving psychologic dynamics of individuals involved in sport and elite performance are intriguing and unique. A specialized knowledge base, training, and experience in providing psychologic services are required to treat this unique population. Counseling and clinical issues of the athlete and elite performer require further attention in the realm of psychologic interventions, including further exploration of the efficacy of interventions for performance enhancement. The field of applied sport psychology may offer the physical medicine

  6. Financial Transaction Tax (Davek na finančne transakcije

    Directory of Open Access Journals (Sweden)

    Meta Ahtik

    2014-10-01

    Full Text Available Financial transaction tax has been proposed already by Keynes; however it has been introduced only in some individual countries and not globally, which would reduce possibilities for tax evasion. Nevertheless, the topic gained importance during the recent financial crisis – the tax is supposed to reduce risky activities of the financial industry and fill the budgets with the means for alleviating the consequences of the crisis, largely caused by the financial industry. Proposal of the European Commission is therefore the first concrete proposal that addresses a wider economic area. This paper investigates economic, theoretical rationale for the introduction of a financial transaction tax and studies its structure and consequences in several European countries: United Kingdom, France, Italy and Sweden. Special emphasis is given to the proposal of the European Commission that would, in case it is confirmed, apply also to Slovenia, although some concerns have arisen recently, weather Slovenia should introduce the tax or not.

    2011-09-01

    Full Text Available Myriad methods exist for analyzing qualitative data. It is, however, imperative for qualitative researchers to employ data analysis tools that are congruent with the theoretical frameworks underpinning their inquiries. In this paper, I have constructed a framework for analyzing data that could be useful for researchers interested in focusing on the transactional nature of language as they engage in Social Science research. Transactional Analysis (TA is an inductive approach to data analysis that transcends constant comparative methods of exploring data. Drawing on elements of narrative and thematic analysis, TA uses the theories of Bakhtin and Rosenblatt to attend to the dynamic processes researchers identify as they generate themes in their data and seek to understand how their participants' worldviews are being shaped. This paper highlights the processes researchers can utilize to study the mutual shaping that occurs as participants read and enter into dialogue with the world around them.

    — In 2013, AEP Ohio (AEP) operated a 5-minute real-time price (RTP) electricity market system on 4 distribution feeders as part of their gridSMART® demonstration project. The RTP households were billed for their electricity usage according to an RTP tariff approved by the Public Utility Commission of Ohio. They were given the incentive that their annual bill would be no greater than if they were on the flat-rate tariff, but they had financial incentives to shift consumption from high price periods to low price periods. Incentives were also available for response under high prices from local events, such as reaching the distribution feeder capacity or a critical peak pricing event. An analysis of this transactive system experiment was completed in early 2014. This paper describes the incentive provided to the customer, the nature of their interaction with the smart thermostat that provided automated response to the transactive signal, and their level of satisfaction with the program.

  9. An Environment for Flexible Advanced Compensations of Web Service Transactions

    2008-01-01

    Business to business integration has recently been performed by employing Web service environments. Moreover, such environments are being provided by major players on the technology markets. Those environments are based on open specifications for transaction coordination. When a failure...... in such an environment occurs, a compensation can be initiated to recover from the failure. However, current environments have only limited capabilities for compensations, and are usually based on backward recovery. In this article, we introduce an environment to deal with advanced compensations based on forward...... recovery principles. We extend the existing Web service transaction coordination architecture and infrastructure in order to support flexible compensation operations. We use a contract-based approach, which allows the specification of permitted compensations at runtime. We introduce abstract service...

    Directory of Open Access Journals (Sweden)

    J.L. Walter Jeyakumar

    2010-12-01

    Full Text Available We present a mobile transaction framework in which mobile users can share data which is stored in the cache of a mobile agent. This mobile agent is a special mobile node which coordinates the sharing process. The proposed framework allows mobile affiliation work groups to be formed dynamically with a mobile agent and mobile hosts. Using short range wireless communication technology, mobile users can simultaneously access the data from the cache of the mobile agent. The data Access Manager module at the mobile agent enforces concurrency control using cache invalidation technique. This model supports disconnected mobile computing allowing mobile agent to move along with the Mobile Hosts. The proposed Transaction frame work has been simulated in Java 2 and performance of this scheme is compared with existing frame works.

  11. The Transaction Footprints of Scottish Food And Drink SMEs

    Directory of Open Access Journals (Sweden)

    Copus Andrew

    2016-09-01

    Full Text Available This paper presents a survey approach to measuring the “transaction footprints” of rural small and medium sized enterprises (SMEs. Combined with a graphical presentation of results, this contributes to the evidence base on the roles of local and global linkages. Findings suggest that the food and drink industry of Scotland is relatively localised in its input and sales interaction pattern, although substantial variations, associated with product specialisms, remoteness/accessibility, input purchasing and marketing strategies, exist. Localised SMEs have weathered the recession slightly better, but more outward-looking in firms tend to have greater optimism about the future. Transaction footprint analysis should be viewed as component of an ongoing process of re-mapping the network infrastructure of the rural economy, alongside analysis of untraded interdependencies, and institutional networks in the realm of governance.

    2013-03-01

    Full Text Available This paper proposes a model to represent people´s work from ontological business transactions according to the concepts of Activity Theory and Enterprise Ontology. With this model we aim at providing a comprehensive and structured modelling approach that, at the same time, avoids excessively detailed descriptions of technology-supported activities. The proposed model is complemented with a set of rules that enables the interrelating transactions described with the Enterprise Ontology language and task descriptions based on Activity Theory. An important benefit of this model is enabling the analysis of manifested contradictions to identify the aspects needing changes within organizational activity systems. The proposed model and rules were applied in a study case.

    Grill, Martin; Pousette, Anders; Nielsen, Kent; Grytnes, Regine; Törner, Marianne

    2017-07-01

    Objectives The construction industry accounted for >20% of all fatal occupational accidents in Europe in 2014. Leadership is an essential antecedent to occupational safety. The aim of the present study was to assess the influence of transformational, active transactional, rule-oriented, participative, and laissez-faire leadership on safety climate, safety behavior, and accidents in the Swedish and Danish construction industry. Sweden and Denmark are similar countries but have a large difference in occupational accidents rates. Methods A questionnaire study was conducted among a random sample of construction workers in both countries: 811 construction workers from 85 sites responded, resulting in site and individual response rates of 73% and 64%, respectively. Results The results indicated that transformational, active transactional, rule-oriented and participative leadership predict positive safety outcomes, and laissez-faire leadership predict negative safety outcomes. For example, rule-oriented leadership predicts a superior safety climate (β=0.40, Pleadership on workers' safety behavior was moderated by the level of participative leadership (β=0.10, Pleadership behaviors on safety outcomes were largely similar in Sweden and Denmark. Rule-oriented and participative leadership were more common in the Swedish than Danish construction industry, which may partly explain the difference in occupational accident rates. Conclusions Applying less laissez-faire leadership and more transformational, active transactional, participative and rule-oriented leadership appears to be an effective way for construction site managers to improve occupational safety in the industry.

  17. Historizing epistemology in psychology.

    Science.gov (United States)

    Jovanović, Gordana

    2010-12-01

    The conflict between the psychometric methodological framework and the particularities of human experiences reported in psychotherapeutic context led Michael Schwarz to raise the question whether psychology is based on a methodological error. I take this conflict as a heuristic tool for the reconstruction of the early history of psychology, which bears witness to similar epistemological conflicts, though the dominant historiography of psychology has largely forgotten alternative conceptions and their valuable insights into complexities of psychic phenomena. In order to work against the historical amnesia in psychology I suggest to look at cultural-historical contexts which decisively shaped epistemological choices in psychology. Instead of keeping epistemology and history of psychology separate, which nurtures individualism and naturalism in psychology, I argue for historizing epistemology and for historical psychology. From such a historically reflected perspective psychology in contemporary world can be approached more critically.

  6. Austrian Economics and the Transaction Cost Approach to the Firm

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available As the transaction cost theory of the firm was taking shape in the 1970s, another important movement in economics was emerging: a revival of the ‘Austrian’ tradition in economic theory associated with such economists as Ludwig von Mises and F. A. Hayek (1973; Dolan, 1976; Spadaro, 1978. As Oliver Williamson has pointed out, Austrian economics is among the diverse sources for transaction cost economics. In particular, Williamson frequently cites Hayek (e.g., Williamson, 1985, p. 8; 1991, p. 162, particularly Hayek’s emphasis on adaptation as a key problem of economic organisation (Hayek, 1945. Following Williamson’s lead, a reference to Hayek’s ‘The Use of Knowledge in Society’ (Hayek, 1945 has become almost mandatory in discussions of economic organisation (e.g., Ricketts, 1987, p. 59; Milgrom and Roberts, 1992, p. 56; Douma and Schreuder 1991, p. 9. However, there are many other potential links between Austrian and transaction cost economics that have not been explored closely and exploited.This article argues that characteristically Austrian ideas about property, entrepreneurship, economic calculation, tacit knowledge, and the temporal structure of capital have important implications for theories of economic organisation, transaction cost economics in particular. Austrian economists have not, however, devoted substantial attention to the theory of the firm, preferring to focus on business-cycle theory, welfare economics, political economy, comparative economic systems, and other areas. Until recently the theory of the firm was an almost completely neglected area in Austrian economics, but over the last decade, a small Austrian literature on the firm has emerged. While these works cover a wide variety of theoretical and applied topics, their authors share the view that Austrian insights have something to offer students of firm organisation.

  7. A Multi-threading Architecture for Multilevel Secure Transaction Processing

    A TCB and security kernel architecture for supporting multi-threaded, queue-driven transaction processing applications in a multilevel secure environment is presented. Our design exploits hardware security features of the Intel 80x86 processor family. Intel's CPU architecture provides hardware with two distinct descriptor tables. We use one of these in the usual way for process isolation. For each process, the descriptor table holds the descriptors of "system-low" segments, such as code segme...

  12. Globalisation and blood safety.

    Farrugia, Albert

    2009-05-01

    Globalisation may be viewed as the growing interdependence of countries worldwide through the increasing volume and variety of cross-border transactions in goods and services, and also through the more rapid and widespread diffusion of technology. Globalisation is not just an economic phenomenon, although it is frequently described as such, but includes commerce, disease and travel, and immigration, and as such it affects blood safety and supply in various ways. The relatively short travel times offered by modern aviation can result in the rapid spread of blood-borne pathogens before measures to counteract transmission can be put in place; this would have happened with SARS if the basic life cycle of the SARS virus included an asymptomatic viraemia. This risk can be amplified by ecological factors which effect the spread of these pathogens once they are transferred to a naïve ecosystem, as happened with West Nile Virus (WNV) in North America. The rationalization and contraction of the plasma products industry may be viewed as one aspect of globalisation imposed by the remorseless inevitability of the market; the effect of this development on the safety and supply of products has yet to be seen, but the oversight and assurance of a shrinking number of players will present particular challenges. Similarly, the monopolization of technology, through patent enforcement which puts access beyond the reach of developing countries, can have an effect on blood safety. The challenges presented to blood safety by globalisation are heightening the tensions between the traditional focus on the product safety - zero risk paradigm and the need to view the delivery of safe blood as an integrated process. As an illustration of this tension, donor deferral measures imposed by globalisation-induced risks such as vCJD and WNV have resulted in the loss of the safest and most committed portion of the blood donor population in many Western countries, leading to an increased risk to

  13. Linear versus quadratic portfolio optimization model with transaction cost

    Optimization model is introduced to become one of the decision making tools in investment. Hence, it is always a big challenge for investors to select the best model that could fulfill their goal in investment with respect to risk and return. In this paper we aims to discuss and compare the portfolio allocation and performance generated by quadratic and linear portfolio optimization models namely of Markowitz and Maximin model respectively. The application of these models has been proven to be significant and popular among others. However transaction cost has been debated as one of the important aspects that should be considered for portfolio reallocation as portfolio return could be significantly reduced when transaction cost is taken into consideration. Therefore, recognizing the importance to consider transaction cost value when calculating portfolio' return, we formulate this paper by using data from Shariah compliant securities listed in Bursa Malaysia. It is expected that, results from this paper will effectively justify the advantage of one model to another and shed some lights in quest to find the best decision making tools in investment for individual investors.

  14. Resilient data staging through MxN distributed transactions.

    Scientific computing-driven discoveries are frequently driven from workflows that use persistent storage as a staging area for data between operations. With the bad and progressively worse bandwidth vs. data size issues as we continue towards exascale, eliminating persistent storage through techniques like data staging will both enable these workflows to continue online, but also enable more interactive workflows reducing the time to scientific discoveries. Data staging has shown to be an effective way for applications running on high-end computing platforms to offload expensive I/O operations and to manage the tremendous amounts of data they produce. This data staging approach, however, lacks the ACID style guarantees traditional straight-to-disk methods provide. Distributed transactions are a proven way to add ACID properties to data movements, however distributed transactions follow 1xN data movement semantics, where our highly parallel HPC environments employ MxN data movement semantics. In this paper we present a novel protocol that extends distributed transaction terminology to include MxN semantics which allows our data staging areas to benefit from ACID properties. We show that with our protocol we can provide resilient data staging with a limited performance penalty over current data staging implementations.

  15. Financial sector taxation: Financial activities tax or financial transaction tax?

    Full Text Available The recent financial crises has revealed the need to improve and ensure the stability of the financial sector to reduce negative externalities, to ensure fair and substantial contribution of the financial sector to the public finances and the need to consolidate public finance. All those needs represent substantial arguments for the discussion about the introduction of financial sector taxation. There are discussed in the paper two possible schemes of financial sector taxation – financial transaction tax and financial activities tax. The aim of the paper is to research the possibility of the introduction of financial sector taxation, to discuss the pros and cons of two major candidates on financial sector taxation – financial transaction tax and financial activities tax and to suggest the possible candidate suitable for the implementation on the EU level. Financial transaction tax represents the tool suitable mainly on global level, for only in that case enables generate sufficient financial resources. From EU point of view is considered as less suitable, for it bears the risk of reallocation. Therefore the introduction of financial activities tax on EU level is considered as a better solution for the financial sector taxation in the EU, for financial sector is exempted from value added tax. With respect to the fact, that the implementation would represent the innovative approach to the financial sector taxation, there are no empirical proves and therefore this could be the subject of further research.

  16. [Pay for performance explained by transaction costs theory].

    To evaluate the ability of transaction costs theory to explain incentives in the health care chain. We performed a case study of CPS, a health insurance company in Bogota (Colombia), which preferred not to publish its name. CPS moves in the environment of high transaction costs and uses the hybrid form of governance at the outpatient level. Incentive intensity, administrative control and the contract all agree with the theory. At the hospital level, the market is used, despite greater uncertainty. Because of the discrete form (1.0) of the incentives and the absence of administrative control, it is difficult for CPS to relate payment to hospital performance. Transaction costs theory explains the configuration of incentives. Another contribution made by this theory to the literature is the criterion to differentiate between the market and the hybrid. We propose that the market uses discrete-type (1.0) incentives, while the hybrid uses continuous, commission-like incentives. Copyright © 2011 SESPAS. Published by Elsevier Espana.

  17. Group theories: relevance to group safety studies.

    Science.gov (United States)

    Benevento, A L

    1998-01-01

    Promoting safety in the workplace has been attempted in a variety of ways. Increasingly, industries are using groups such as safety teams and quality circles to promote worker safety. Group influences on individual behavior and attitudes have long been studied in the social psychology literature, but the theories have not been commonly found outside the psychology arena. This paper describes the group theories of group polarization, risky shift, social loafing, groupthink and team think and attempts to apply these theories to existing studies that examine work group influences on safety. Interesting parallels were found but only one study examined group influences as their primary focus of research. Since groups are increasingly used for safety promotion, future research on safety that studies group influences with respect to current group theories is recommended.

    This study examined the underlying mechanisms through which transformational and transactional leadership influence employee safety behaviors. Linking leadership theory with self-regulatory focus (SRF) theory, we examined a model of dual effects of leadership on safety initiative and safety compliance behaviors as mediated by promotion and prevention self-regulations. We conducted an experimental study (N = 107), an online study (N = 99) and a field study (N = 798 employees and 49 managers). Results demonstrated that followers' situational promotion focus mediated the positive relationship between transformational leadership and safety initiative behaviors. Through all 3 studies, transactional active leadership was positively associated with followers' situational prevention focus, however, the association between followers' prevention focus and safety compliance behaviors was inconsistent, showing the expected mediation relationships in the experimental setting, but not in the online and field studies. We discuss theoretical and practical implications of the findings. (c) 2015 APA, all rights reserved).

    This paper describes the history and current status of professional psychology in Portugal where a unique perspective combines training, research, and practical contributions from Europe and the Americas with their own history of psychological tradition and expertise. Training in professional psychology includes Social Psychology and Educational and Vocational Guidance specializations in addition to Clinical Psychology and Psychotherapy and Counseling for the professional degree, Licenciatura. Advanced degrees are offered in Environmental Psychology, Career Development, Social Cognition, and other areas, primarily for academic positions. Research in all of these areas is expected to have applied outcomes that contribute to individual well being and an improved quality of life for the entire population. The result has been a rapid development of an indigenous professional psychology to address mental health, social, and environmental concerns that compel psychological attention and resources worldwide as well as those problems of local and national origins.
