  3. Tabled Execution in Scheme

    Energy Technology Data Exchange (ETDEWEB)

    Willcock, J J; Lumsdaine, A; Quinlan, D J

    2008-08-19

    Tabled execution is a generalization of memorization developed by the logic programming community. It not only saves results from tabled predicates, but also stores the set of currently active calls to them; tabled execution can thus provide meaningful semantics for programs that seemingly contain infinite recursions with the same arguments. In logic programming, tabled execution is used for many purposes, both for improving the efficiency of programs, and making tasks simpler and more direct to express than with normal logic programs. However, tabled execution is only infrequently applied in mainstream functional languages such as Scheme. We demonstrate an elegant implementation of tabled execution in Scheme, using a mix of continuation-passing style and mutable data. We also show the use of tabled execution in Scheme for a problem in formal language and automata theory, demonstrating that tabled execution can be a valuable tool for Scheme users.

    Studies of learning and student satisfaction in the context of online university programs have largely neglected programs catering specifically to business executives. Such executives have typically been away from higher education for a number of years, and have collected substantial practical...... experience in the subject matters they are taught. Their expectations in terms of both content and delivery may therefore be different from non-executive students. We explore perceptions of the quality of tutoring in the context of an online executive MBA program through participant interviews. We find...... that in addition to some of the tutor behaviors already discussed in the literature, executive students look specifically for practical industry knowledge and experience in tutors, when judging how effective a tutor is. This has implications for both the recruitment and training of online executive MBA tutors....

  5. Executive functions in synesthesia.

    Rouw, Romke; van Driel, Joram; Knip, Koen; Richard Ridderinkhof, K

    2013-03-01

    In grapheme-color synesthesia, a number or letter can evoke two different and possibly conflicting (real and synesthetic) color sensations at the same time. In this study, we investigate the relationship between synesthesia and executive control functions. First, no general skill differences were obtained between synesthetes and non-synesthetes in classic executive control paradigms. Furthermore, classic executive control effects did not interact with synesthetic behavioral effects. Third, we found support for our hypothesis that inhibition of a synesthetic color takes effort and time. Finally, individual differences analyses showed no relationship between the two skills; performance on a 'normal' Stroop task does not predict performance on a synesthetic Stroop task. Across four studies, the current results consistently show no clear relationship between executive control functions and synesthetic behavioral effects. This raises the question of which mechanisms are at play in synesthetic 'management' during the presence of two conflicting (real and synesthetic) sensations. Copyright © 2012 Elsevier Inc.

  7. Executions and scientific anatomy.

    Science.gov (United States)

    Dolezal, Antonín; Jelen, Karel; Stajnrtova, Olga

    2015-12-01

    The very word "anatomy" tells us about this branch's connection with dissection. Studies of anatomy have taken place for approximately 2.300 years already. Anatomy's birthplace lies in Greece and Egypt. Knowledge in this specific field of science was necessary during surgical procedures in ophthalmology and obstetrics. Embalming took place without public disapproval just like autopsies and manipulation with relics. Thus, anatomical dissection became part of later forensic sciences. Anatomical studies on humans themselves, which needed to be compared with the knowledge gained through studying procedures performed on animals, elicited public disapprobation and prohibition. When faced with a shortage of cadavers, anatomists resorted to obtaining bodies of the executed and suicide victims - since torture, public display of the mutilated body, (including anatomical autopsy), were perceived as an intensification of the death penalty. Decapitation and hanging were the main execution methods meted out for death sentences. Anatomists preferred intact bodies for dissection; hence, convicts could thus avoid torture. This paper lists examples of how this process was resolved. It concerns the manners of killing, vivisection on people in the antiquity and middle-ages, experiments before the execution and after, vivifying from seeming death, experiments with galvanizing electricity on fresh cadavers, evaluating of sensibility after guillotine execution, and making perfect anatomical preparations and publications during Nazism from fresh bodies of the executed.

  9. Executions in The Bahamas

    Directory of Open Access Journals (Sweden)

    Lofquist, William Steele

    2010-01-01

    Full Text Available The stories of those who have been executed in the Bahamas are heretofore untold. In telling these stories and in linking them to the changing course of Bahamian history, the present research adds an important dimension to our understanding of Bahamian history and politics. The major theme of this effort is that the changing practice of the death penalty is much more than a consequence of changes in crime. The use of the death penalty parallels the changing interests of colonial rulers, the changing practice of slavery, and the changing role of the Bahamas in colonial and regional affairs. Four distinctive eras of death penalty practice can be identified: (1 the slave era, where executions and commutations were used liberally and with a clear racial patterning; (2 a long era of stable colonialism, a period of marginalization and few executions; (3 an era of unstable colonialism characterized by intensive and efficient use of the death penalty; and (4 the current independence era of high murder rates and equally high impediments to the use of executions.

  16. EXECUTIVE FUNCTIONING IN SCHIZOPHRENIA

    Directory of Open Access Journals (Sweden)

    Gricel eOrellana

    2013-06-01

    Full Text Available The executive function (EF is a set of abilities, which allows us to invoke voluntary control of our behavioral responses. These functions enable human beings to develop and carry out plans, make up analogies, obey social rules, solve problems, adapt to unexpected circumstances, do many tasks simultaneously and locate episodes in time and place. EF includes divided attention and sustained attention, working memory, set-shifting, flexibility, planning and the regulation of goal directed behavior and can be defined as a brain function underlying the human faculty to act or think not only in reaction to external events but also in relation with internal goals and states. EF is mostly associated with dorsolateral prefrontal cortex (PFC. Besides EF, PFC is involved in self-regulation of behavior, i.e. the ability to regulate behavior according to internal goals and constraints, particularly in less structured situations. Self-regulation of behavior is subtended by ventral medial /orbital PFC. Impairment of EF is one of the most commonly observed deficits in schizophrenia through the various disease stages. Impairment in tasks measuring conceptualization, planning, cognitive flexibility, verbal fluency, ability to solve complex problems and working memory occur in schizophrenia. Disorders detected by executive tests are consistent with evidence from functional neuroimaging, which have shown PFC dysfunction in patients while performing these kinds of tasks. Schizophrenics also exhibit deficit in odor identifying, decision-making and self-regulation of behavior suggesting dysfunction of the orbital PFC. However, impairment in executive tests is explained by dysfunction of prefronto-striato-thalamic, prefronto-parietal and prefronto-temporal neural networks mainly. Disorders in executive functions may be considered central facts with respect to schizophrenia and it has been suggested that negative symptoms may be explained by that executive dysfunction.

  17. High-performing physician executives.

    Science.gov (United States)

    Brown, M; Larson, S R; McCool, B P

    1988-01-01

    Physician leadership extends beyond traditional clinical disciplines to hospital administration, group practice management, health policy making, management of managed care programs, and many business positions. What kind of person makes a good physician executive? What stands out as the most important motivations, attributes, and interests of high-performing physician executives? How does this compare with non-physician health care executives? Such questions have long been high on the agenda of executives in other industries. This article builds on existing formal assessments of leadership attributes of high-performing business, government, and educational executives and on closer examination of health care executives. Previous studies looked at the need for innovative, entrepreneurial, energetic, community-oriented leaders for positions throughout health care. Traits that distinguish excellence and leadership were described by Brown and McCool.* That study characterized successful leaders in terms of physical strengths (high energy, good health, and propensity for hard work), mental strengths (creativity, intuition, and innovation), and organizational strengths (mission orientation, vision, and entrepreneurial spirit). In this investigation, a subset of health care executives, including physician executives, was examined more closely. It was initially assumed that successful physician executives exhibit many of the same positive traits as do nonphysician executives. This assumption was tested with physician leaders in a range of administrative and managerial positions. We also set out to identify key differences between physician and nonphysician executives. Even with our limited exploration, it seems to us that physician executives probably do differ from nonphysician executives.

  18. What executives should remember.

    Science.gov (United States)

    Drucker, Peter F

    2006-02-01

    In more than 30 essays for Harvard Business Review, Peter Drucker (1909-2005) urged readers to take on the hard work of thinking--always combined, he insisted, with decisive action. He closely analyzed the phenomenon of knowledge work--the growing call for employees who use their minds rather than their hands--and explained how it challenged the conventional wisdom about the way organizations should be run. He was intrigued by employees who knew more about certain subjects than their bosses or colleagues but who still had to cooperate with others in a large organization. As the business world matured in the second half of the twentieth century, executives came to think that they knew how to run companies--and Drucker took it upon himself to poke holes in their assumptions, lest organizations become stale. But he did so sympathetically, operating from the premise that his readers were intelligent, hardworking people of goodwill. Well suited to HBR's format of practical, idea-based essays for executives, his clear-eyed, humanistic writing enriched the magazine time and again. This article is a compilation of the savviest management advice Drucker offered HBR readers over the years--in short, his greatest hits. It revisits the following insightful, influential contributions: "The Theory of the Business" (September-October 1994), "Managing for Business Effectiveness" (May-June 1963), "What Business Can Learn from Nonprofits" (July-August 1989), "The New Society of Organizations" (September-October 1992), "The Information Executives Truly Need" (January-February 1995), "Managing Oneself" (March-April 1999 republished January 2005), "They're Not Employees, They're People" (February 2002), "What Makes an Effective Executive" (June 2004).

  20. Income, neural executive processes, and preschool children's executive control.

    Ruberry, Erika J; Lengua, Liliana J; Crocker, Leanna Harris; Bruce, Jacqueline; Upshaw, Michaela B; Sommerville, Jessica A

    2017-02-01

    This study aimed to specify the neural mechanisms underlying the link between low household income and diminished executive control in the preschool period. Specifically, we examined whether individual differences in the neural processes associated with executive attention and inhibitory control accounted for income differences observed in performance on a neuropsychological battery of executive control tasks. The study utilized a sample of preschool-aged children (N = 118) whose families represented the full range of income, with 32% of families at/near poverty, 32% lower income, and 36% middle to upper income. Children completed a neuropsychological battery of executive control tasks and then completed two computerized executive control tasks while EEG data were collected. We predicted that differences in the event-related potential (ERP) correlates of executive attention and inhibitory control would account for income differences observed on the executive control battery. Income and ERP measures were related to performance on the executive control battery. However, income was unrelated to ERP measures. The findings suggest that income differences observed in executive control during the preschool period might relate to processes other than executive attention and inhibitory control.

The authors' findings give new life to the debate over the relative importance of profitability versus sales as determinants of e...

  3. Build and Execute Environment

    Energy Technology Data Exchange (ETDEWEB)

    2017-04-21

    At exascale, the challenge becomes to develop applications that run at scale and use exascale platforms reliably, efficiently, and flexibly. Workflows become much more complex because they must seamlessly integrate simulation and data analytics. They must include down-sampling, post-processing, feature extraction, and visualization. Power and data transfer limitations require these analysis tasks to be run in-situ or in-transit. We expect successful workflows will comprise multiple linked simulations along with tens of analysis routines. Users will have limited development time at scale and, therefore, must have rich tools to develop, debug, test, and deploy applications. At this scale, successful workflows will compose linked computations from an assortment of reliable, well-defined computation elements, ones that can come and go as required, based on the needs of the workflow over time. We propose a novel framework that utilizes both virtual machines (VMs) and software containers to create a workflow system that establishes a uniform build and execution environment (BEE) beyond the capabilities of current systems. In this environment, applications will run reliably and repeatably across heterogeneous hardware and software. Containers, both commercial (Docker and Rocket) and open-source (LXC and LXD), define a runtime that isolates all software dependencies from the machine operating system. Workflows may contain multiple containers that run different operating systems, different software, and even different versions of the same software. We will run containers in open-source virtual machines (KVM) and emulators (QEMU) so that workflows run on any machine entirely in user-space. On this platform of containers and virtual machines, we will deliver workflow software that provides services, including repeatable execution, provenance, checkpointing, and future proofing. We will capture provenance about how containers were launched and how they interact to annotate

    Full Text Available Orientation: Psychologists in industry are increasingly required to provide executive coaching services in their organisations or as part of their consulting services. An evaluation of coaching models as well as the development needs of individuals being trained as coaches, both locally and internationally, has led the authors to believe that there is a need for a competence executive coaching model.Research purpose: The purpose of this article is to address the training and development needs of these consulting psychologists by presenting a competence executive coaching model for the planning, implementation and evaluation of executive coaching interventions.Research design, approach and method: The study was conducted while one of the authors was involved in teaching doctoral students in consulting psychology and executive coaching, specifically in the USA. The approach involved a literature review of executive coaching models and a qualitative study using focus groups to develop and evaluate the competence executive coaching model.Main findings: The literature review provided scant evidence of competence executive coaching models and there seems to be a specific need for this in the training of coaches in South Africa. Hence the model that was developed is an attempt to provide trainers with a structured model for the training of coaches.Contribution/value-add: The uniqueness of this competence model is not only described in terms of the six distinct coaching intervention phases, but also the competencies required in each.

  11. Executive control influences linguistic representations.

    Science.gov (United States)

    Lev-Ari, Shiri; Keysar, Boaz

    2014-02-01

    Although it is known that words acquire their meanings partly from the contexts in which they are used, we proposed that the way in which words are processed can also influence their representation. We further propose that individual differences in the way that words are processed can consequently lead to individual differences in the way that they are represented. Specifically, we showed that executive control influences linguistic representations by influencing the coactivation of competing and reinforcing terms. Consequently, people with poorer executive control perceive the meanings of homonymous terms as being more similar to one another, and those of polysemous terms as being less similar to one another, than do people with better executive control. We also showed that bilinguals with poorer executive control experience greater cross-linguistic interference than do bilinguals with better executive control. These results have implications for theories of linguistic representation and language organization.

    2015-01-01

    Children spend a lot of time watching television on its many platforms: directly, online, and via videos and DVDs. Many researchers are concerned that some types of television content appear to negatively influence children's executive function. Because (1) executive function predicts key developmental outcomes, (2) executive function appears to be influenced by some television content, and (3) American children watch large quantities of television (including the content of concern), the issues discussed here comprise a crucial public health issue. Further research is needed to reveal exactly what television content is implicated, what underlies television's effect on executive function, how long the effect lasts, and who is affected. © 2015 Elsevier Inc.

    Directory of Open Access Journals (Sweden)

    ALFREDO eSPAGNA

    2015-02-01

    Full Text Available The human attentional system can be subdivided into three functional networks of alerting, orienting, and executive control. Although these networks have been extensively studied in the visuospatial modality, whether the same mechanisms are deployed across different sensory modalities remains unclear. In this study we used the attention network test for visuospatial modality, in addition to two auditory variants with spatial and frequency manipulations to examine cross-modal correlations between network functions. Results showed that among the visual and auditory tasks the effects of executive control, but not effects of alerting and orienting were significantly correlated. These findings suggest that while alerting and orienting functions rely more upon modality specific processes, the executive control of attention coordinates complex behavior via supramodal mechanisms.

    Outplacement service (OPS) is a human resource service provided by organizations to terminated executives. In addition to assisting organizations with the mechanics of the termination process, OPS helps terminated executives cope with the trauma of job loss and find new employment. Given the frequent involvement of nurse executives in termination decisions and the risk of termination inherent in their own positions, nurse executives have a vested interest in OPS policies and programs.

  6. CSP for Executable Scientific Workflows

    DEFF Research Database (Denmark)

    Friborg, Rune Møllegaard

    This thesis presents CSP as a means of orchestrating the execution of tasks in a scientific workflow. Scientific workflow systems are popular in a wide range of scientific areas, where tasks are organised in directed graphs. Execution of such graphs is handled by the scientific workflow systems...... and the readability of Python source code. Python is a popular programming language in the scientific community, with many scientific libraries (modules) and simple integration to external languages. This thesis presents a PyCSP extended with many new features and a more robust implementation to allow scientific...... applications to run on heterogenous hardware, combining multiple hardware architectures. This is especially important in scientific computing as the performance of computational tasks may be orders of magnitude faster depending on the hardware architecture used. To ensure the robustness of the PyCSP library...

  7. Executive Information Systems' Multidimensional Models

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Executive Information Systems are design to improve the quality of strategic level of management in organization through a new type of technology and several techniques for extracting, transforming, processing, integrating and presenting data in such a way that the organizational knowledge filters can easily associate with this data and turn it into information for the organization. These technologies are known as Business Intelligence Tools. But in order to build analytic reports for Executive Information Systems (EIS in an organization we need to design a multidimensional model based on the business model from the organization. This paper presents some multidimensional models that can be used in EIS development and propose a new model that is suitable for strategic business requests.

  8. What makes an effective executive.

    Science.gov (United States)

    Drucker, Peter F

    2004-06-01

    An effective executive does not need to be a leader in the typical sense of the word. Peter Drucker, the author of more than two dozen HBR articles, says some of the best business and nonprofit CEOs he has worked with over his 65-year consulting career were not stereotypical leaders. They ranged from extroverted to nearly reclusive, from easygoing to controlling, from generous to parsimonious. What made them all effective is that they followed the same eight practices: They asked, "What needs to be done?" They also asked, "What is right for the enterprise?" They developed action plans. They took responsibility for decisions. They took responsibility for communicating. They were focused on opportunities rather than problems. They ran productive meetings. And they thought and said "we" rather than "I." The first two practices provided them with the knowledge they needed. The next four helped them convert this knowledge into effective action, for knowledge is useless to executives until it has been translated into deeds. The last two ensured that the whole organization felt responsible and accountable. Effective executives know that they have authority only because they have the trust of the organization. This means they must think of the needs and opportunities of the organization before they think of their own needs and opportunities. The author also suggests a ninth practice that's so important, he elevates it to the level of a rule: Listen first, speak last. The demand for effective executives is much too great to be satisfied by those few people who are simply born to lead. Effectiveness is a discipline. And, like every discipline, it can be learned and must be earned.

    Full Text Available The objective of this paper is to present the software architecture used for the OPERANDO privacy platform, funded by the European Union in a Horizon 2020 project. For integration, OPERANDO is using SwarmESB, an open source Enterprise Service Bus (ESB based on executable choreographies. In this paper we are presenting the concept of service transformations, presented as a bridge between the world of REST web services and the world of services implemented with executable choreographies. These transformations are improving the heterogeneity aspects when we are analysing SwarmESB as a distributed system. Five types of transformations that have been analysed and implemented as open source software have been integrated. This proposal is shaped around a common language capable of expressing all these five transformation types we have identified working for OPERANDO. Therefore, the Domain Specific Language proposed, renders the essential elements for transformations among functions, web services and executable choreographies. This unification will trigger a quantitative effect on the productivity of the teams creating or integrating web services in a federated service bus environment which is a key architectural component in the future Internet-of-Things and cloud systems.

    Having hit power limitations to even more aggressive out-of-order execution in processor cores, many architects in the past decade have turned to single-instruction-multiple-data (SIMD) execution to increase single-threaded performance. SIMD execution, or having a single instruction drive execution of an identical operation on multiple data items, was already well established as a technique to efficiently exploit data parallelism. Furthermore, support for it was already included in many commodity processors. However, in the past decade, SIMD execution has seen a dramatic increase in the set of

Attention is given to the language syntax, data structures and recursion, constructs that alter control, predicates that modify the database, predicates for input and output, and metalogical predicates. The parts of the Warren Abstract Machine are then described, and it is shown how it executes programs. Parallel architectures proposed for expert systems are examined, and the principal varieties of parallelism available in PROLOG and examples of architectures exploiting them are discussed.

It argues that despite his traumatised responses to public hangings, Dickens is able to use the site of the scaffold to articulate some fundamental human fears and dispositions. The paper compares Dickens’s response to the horrors of the French Revolution with Carlyle’s, and shows throughout how Dickens firmly repudiates Trollope's somewhat rueful dismissal of him as ‘Mr Popular Sentiment’.

  4. The volunteer activities of healthcare executives.

    Weil, Peter A; Kimball, Peter A

    2010-01-01

    The role requirements of healthcare executives have received considerable attention from researchers; however, the volunteer efforts of executives have not been examined. This study investigates the relationship between an executive's position in the organizational hierarchy and his or her propensity to volunteer in general and to volunteer for the executive's professional society in particular. The study found that nearly all executives volunteered for some organization, but the type of work they performed was associated with their position level. For example, more than 90 percent of chief executive officers (CEOs) served on a board or a committee compared with less than half of mid-level executives. Also, more CEOs than lower-level executives were involved in fund-raising, setting professional standards, and testifying to legislatures. In general, we suggest that CEOs commit to volunteering, which facilitates their ability to achieve and retain their high-level position, recognition, and rewards. Fewer than half of the executives surveyed had volunteered for the American College of Healthcare Executives (ACHE), their professional society; the most common reasons given for not volunteering were lack of awareness of volunteer opportunities or not being asked to volunteer. Those that had volunteered for ACHE were primarily motivated by altruistic motives, such as the desire to help others, feelings of compassion for people in need, or the desire to do something for the profession. Career advancement was deemed to be a less important motivator in volunteering for ACHE. However, mid-level executives rated these motives more highly than did senior-level executives and CEOs. Because of the creation of local ACHE chapters, many more opportunities will become available for healthcare executives to volunteer for their professional society in the future.

    Full Text Available The present study was aimed at investigating different aspects of Executive Functions (EF in children with Developmental Dyslexia (DD.A neuropsychological battery tapping verbal fluency, spoonerism, attention, verbal shifting, short-term and working memory was used to assess 60 children with DD and 65 with typical reading abilities.Compared to their controls, children with DD showed deficits in several EF domains such as verbal categorical and phonological fluency, visual-spatial and auditory attention, spoonerism, verbal and visual short-term memory, and verbal working memory. Moreover, exploring predictive relationships between EF measures and reading, we found that spoonerism abilities better explained word and non-word reading deficits. Although to a lesser extent, auditory and visual-spatial attention also explained the increased percentage of variance related to reading deficit.EF deficits found in DD are interpreted as an expression of a deficient functioning of the Central Executive System and are discussed in the context of the recent temporal sampling theory.

    Provides a message passing framework between generic input, model and output drivers, and specifies an API for developing such drivers. Also provides batch and real-time controllers which step the model and I/O through the time domain (or other discrete domain), and sample I/O drivers. This is a library framework, and does not, itself, solve any problems or execute any modeling. The SeMe framework aids in development of models which operate on sequential information, such as time-series, where evaluation is based on prior results combined with new data for this iteration. Has applications in quality monitoring, and was developed as part of the CANARY-EDS software, where real-time water quality data is being analyzed for anomalies.

  17. Executive function and coping in stroke survivors.

    Kegel, Jessica; Dux, Moira; Macko, Richard

    2014-01-01

    Stroke is a leading cause of disability and sequelae may include physical, emotional, and cognitive impairments. The methods employed to cope with distress, both emotional and cognitive, have not been evaluated in individuals post-stroke. However, research in traumatic brain injury (TBI) suggests that executive function is positively correlated with adaptive coping and negatively correlated with maladaptive coping strategies (Krpan et al., 2007). Examination of these constructs post-stroke may assist with enriching our understanding of cognitive and emotional symptomatology and optimize rehabilitation strategies. The present study aimed to assess the association between executive function and coping strategies in a sample of chronic stroke survivors. The researchers hypothesized that executive function would be positively correlated with adaptive coping strategies and negatively correlated with maladaptive coping strategies. Fifteen stroke survivors were administered a battery of cognitive tests assessing executive function and also completed the Ways of Coping Questionnaire (WAYS), a self-report coping measure. Analyses indicated that executive function deficits were related to increased avoidant coping. Contrary to expectations, executive function was not significantly related to active coping. In addition, post hoc analyses revealed that executive function was a significant predictor of avoidant coping after controlling for demographics. Our data, in accordance with prior work in TBI, suggests that executive function and aspects of coping are associated. Rehabilitation strategies that improve executive function may also lead to utilization of adaptive coping strategies. Research has shown that aerobic exercise increases activation in the frontal lobe and improves executive function (Colcombe & Kramer, 2003; Colcombe et al., 2004). Future studies should examine whether aerobic exercise positively affects executive function and coping in stroke survivors.

    Attentional control has been conceptualized as executive functioning by neuropsychologists and as working memory capacity by experimental psychologists. We examined the relationship between these constructs using a factor analytic approach in an adult lifespan sample. Several tests of working memory capacity and executive function were administered to over 200 subjects between the ages of 18-90 years old, along with tests of processing speed and episodic memory. The correlation between working memory capacity and executive functioning constructs was very strong (r = .97), but correlations between these constructs and processing speed were considerably weaker (r's ≈ .79). Controlling for working memory capacity or executive function eliminated age effects on episodic memory, and working memory capacity or executive function accounted for variance in episodic memory beyond that accounted for by processing speed. We conclude that tests of working memory capacity and executive function share a common underlying executive attention component that is strongly predictive of higher-level cognition. PMID:20230116

    Earliest notions concerning autism (Autism Spectrum Disorders, ASD) describe the disturbance in executive functioning. Despite altered definition, executive functioning, expressed as higher cognitive skills required complex behaviors linked to the prefrontal cortex, are defective in autism. Specific difficulties in children presenting autism or verbal disabilities at executive functioning levels have been identified. Nevertheless, the developmental deficit of executive functioning in autism is highly diversified with huge individual variation and may even be absent. The aim of the present study to examine the current standing of intact executive functioning intact in ASD. Analysis of ASD populations, whether high-functioning, Asperger's or autism Broad Phenotype, studied over a range of executive functions including response inhibition, planning, cognitive flexibility, cognitive inhibition, and alerting networks indicates an absence of damage/impairment compared to the typically-developed normal control subjects. These findings of intact executive functioning in ASD subjects provide a strong foundation on which to construct applications for growth environments and the rehabilitation of autistic subjects.

    To investigate the relationship between nurse executive leadership and organizational commitment among nurses in acute care hospitals. A key challenge for organizations is to maximize the contributions of all workers by cultivating their commitment. Nurse leaders are in a position to influence organizational commitment among nurses. The theoretical constructs underlying this study are the transformational leadership theory and the Etzioni's organizational theory. A cross-sectional, field survey of nurse executives, nurse managers, and staff nurses was conducted to assess nurse executive transformational and transactional leadership and their relationship to organizational commitment. Hypotheses were tested using correlational analysis, and univariate statistics were used to describe the sample. An inverse relationship between nurse executive transformational and transactional leadership and alienative (highly negative) organizational commitment was statistically significant. A positive association was demonstrated between nurse executive leadership and nurse manager leadership. This study supports the effect of nurse executive leadership on nurse manager leadership and on organizational commitment among nurses despite role distance. To the extent that transformational leadership is present, alienative organizational commitment is reduced. This relationship shows the importance of nurse executive leadership in organizational involvement among nurses in the dynamic context of contemporary hospital settings.

    The overall comparison of senior executive demand shows that corporate CEOs see a greater need for senior managers during the next year, but both groups concur on the need for more senior executives in the long term. Although the CEOs agree on the increase in demand in marketing/sales and information systems/data processing during each time frame, hospital CEOs will require fewer senior executives in general management and their corporate peer call for fewer planning/corporate development professionals, reflecting the respective changes occurring in both sectors surveyed.

    Age-related deficits in executive control might lead to socially inappropriate behavior if they compromise the ability to withhold inappropriate responses. Consistent with this possibility, older adults in the current study showed greater social inappropriateness than younger adults--as rated by their peers--and this effect was mediated by deficits in executive control as well as deficits in general cognitive ability. Older adults also responded with greater social inappropriateness to a provocative event in the laboratory, but this effect was unrelated to executive functioning or general cognitive ability. These findings suggest that changes in both social and cognitive factors are important in understanding age-related changes in social behavior.

    We investigate whether the gender of top executives influences a firm’s reaction to competitive pressures. Our empirical approach is based on policy changes that varied the exposure of US banks to competition during the late 1990s. Results suggest that while banks with female executives experience...... significantly higher financial performance under low competition, they tend to underperform when competition increases. At the same time, we find that the presence of female leaders improves the capital stability of banks subject to greater competition.

  10. Executive dysfunction, brain aging, and political leadership.

    Science.gov (United States)

    Fisher, Mark; Franklin, David L; Post, Jerrold M

    2014-01-01

    Decision-making is an essential component of executive function, and a critical skill of political leadership. Neuroanatomic localization studies have established the prefrontal cortex as the critical brain site for executive function. In addition to the prefrontal cortex, white matter tracts as well as subcortical brain structures are crucial for optimal executive function. Executive function shows a significant decline beginning at age 60, and this is associated with age-related atrophy of prefrontal cortex, cerebral white matter disease, and cerebral microbleeds. Notably, age-related decline in executive function appears to be a relatively selective cognitive deterioration, generally sparing language and memory function. While an individual may appear to be functioning normally with regard to relatively obvious cognitive functions such as language and memory, that same individual may lack the capacity to integrate these cognitive functions to achieve normal decision-making. From a historical perspective, global decline in cognitive function of political leaders has been alternatively described as a catastrophic event, a slowly progressive deterioration, or a relatively episodic phenomenon. Selective loss of executive function in political leaders is less appreciated, but increased utilization of highly sensitive brain imaging techniques will likely bring greater appreciation to this phenomenon. Former Israeli Prime Minister Ariel Sharon was an example of a political leader with a well-described neurodegenerative condition (cerebral amyloid angiopathy) that creates a neuropathological substrate for executive dysfunction. Based on the known neuroanatomical and neuropathological changes that occur with aging, we should probably assume that a significant proportion of political leaders over the age of 65 have impairment of executive function.

  11. Statistical Symbolic Execution with Informed Sampling

    Science.gov (United States)

    Filieri, Antonio; Pasareanu, Corina S.; Visser, Willem; Geldenhuys, Jaco

    2014-01-01

    Symbolic execution techniques have been proposed recently for the probabilistic analysis of programs. These techniques seek to quantify the likelihood of reaching program events of interest, e.g., assert violations. They have many promising applications but have scalability issues due to high computational demand. To address this challenge, we propose a statistical symbolic execution technique that performs Monte Carlo sampling of the symbolic program paths and uses the obtained information for Bayesian estimation and hypothesis testing with respect to the probability of reaching the target events. To speed up the convergence of the statistical analysis, we propose Informed Sampling, an iterative symbolic execution that first explores the paths that have high statistical significance, prunes them from the state space and guides the execution towards less likely paths. The technique combines Bayesian estimation with a partial exact analysis for the pruned paths leading to provably improved convergence of the statistical analysis. We have implemented statistical symbolic execution with in- formed sampling in the Symbolic PathFinder tool. We show experimentally that the informed sampling obtains more precise results and converges faster than a purely statistical analysis and may also be more efficient than an exact symbolic analysis. When the latter does not terminate symbolic execution with informed sampling can give meaningful results under the same time and memory limits.

    2015-01-01

    A better understanding of the functioning of the brain, particularly executive functions, of the prison population could aid in reducing crime rates through the reduction of recidivism rates. Indeed, reoffending appears to be related to executive dysfunction and it is known that executive functions are crucial for self-regulation. In the current paper, studies to executive functions in regular adult prisoners compared to non-offender controls were reviewed. Seven studies were found. Specific executive functions were found to be impaired in the general prison population, i.e., attention and set-shifting, as well as in separate subgroups of violent (i.e., set-shifting and working memory) and non-violent offenders (i.e., inhibition, working memory and problem solving). We conclude that the limited number of studies is remarkable, considering the high impact of this population on society and elaborate on the implications of these specific impairments that were found. Further empirical research is suggested, measuring executive functioning within subjects over time for a group of detainees as well as a control group. PMID:25688221

    Trinidad García

    Full Text Available This study analyzes differences in metacognitive skills and executive functioning between two groups of students (10-12 years with different levels of metacognitive knowledge (high n = 50, low n = 64. Groups were established based on students' score on a test of knowledge of strategy use. Metacognitive skills were assessed by means of self-report. Students reported the frequency with which they applied these strategies during the phases of planning, execution, and evaluation of learning. Information about student executive functioning was provided by families and teachers, who completed two parallel forms of a behavior rating scale. The results indicated that: a the group with high levels of metacognitive knowledge reported using their metacognitive skills more frequently than their peers in the other group. These differences were statistically significant in the phases of planning and execution; b both family and teachers informed of better levels of executive functioning in the students with high metacognitive knowledge. Statistically significant differences were found in planning, functional memory, focus, and sustained attention. These results show the existence of an association between different levels of metacognitive knowledge, and differences in metacognitive skills and executive functions, and suggest the need to emphasize this set of variables in order to encourage students to acquire increasing levels of control over their learning process.

    2012-01-01

    Background Narcolepsy with cataplexy (NC) is a disabling sleep disorder characterized by early loss of hypocretin neurons that project to areas involved in the attention network. We characterized the executive control of attention in drug-free patients with NC to determine whether the executive deficits observed in patients with NC are specific to the disease itself or whether they reflect performance changes due to the severity of excessive daytime sleepiness. Methodology Twenty-two patients with NC compared to 22 patients with narcolepsy without cataplexy (NwC) matched for age, gender, intellectual level, objective daytime sleepiness and number of sleep onset REM periods (SOREMPs) were studied. Thirty-two matched healthy controls were included. All participants underwent a standardized interview, completed questionnaires, and neuropsychological tests. All patients underwent a polysomnography followed by multiple sleep latency tests (MSLT), with neuropsychological evaluation performed the same day between MSLT sessions. Principal Findings Irrespective of diagnosis, patients reported higher self-reported attentional complaints associated with the intensity of depressive symptoms. Patients with NC performed slower and more variably on simple reaction time tasks than patients with NwC, who did not differ from controls. Patients with NC and NwC generally performed slower, reacted more variably, and made more errors than controls on executive functioning tests. Individual profile analyses showed a clear heterogeneity of the severity of executive deficit. This severity was related to objective sleepiness, higher number of SOREMPs on the MSLT, and lower intelligence quotient. The nature and severity of the executive deficits were unrelated to NC and NwC diagnosis. Conclusions We demonstrated that drug-free patients with NC and NwC complained of attention deficit, with altered executive control of attention being explained by the severity of objective sleepiness and

    2016-01-01

    High intellectual capacity is a process in development in which the executive functions (inhibition, working memory and flexibility) play a role in the optimal manifestation of their potential. To explore the effectiveness of executive functioning among the profiles of high capacity giftedness and (convergent or divergent) talent. The study examines 78 children with high intellectual capacity aged 8-15 years with profiles of giftedness (n = 21), convergent talent (n = 39) or divergent talent (n = 18). A series of tests were administered including the Battery of Differential and General Aptitudes or the Differential Aptitude Test (depending on the age) and the Torrance Test of Creative Thinking, as well as the Wisconsin Card Sorting Test, the Corsi Test and the Go-No Go Test by means of the Psychology Experiment Building Language platform. A multivariate analysis of variance was performed to determine the relationship between executive function and intellectual profile. Significant differences are obtained between the profiles studied and the executive functions of flexibility and inhibition, but not in working memory. Working memory is similar across the profiles studied, but the complex profile of giftedness displays better executive functioning, with greater flexibility and inhibition than talent, especially of the convergent type.

  1. Musical expertise, bilingualism, and executive functioning.

    Bialystok, Ellen; Depape, Anne-Marie

    2009-04-01

    The authors investigated whether intensive musical experience leads to enhancements in executive processing, as has been shown for bilingualism. Young adults who were bilinguals, musical performers (instrumentalists or vocalists), or neither completed 3 cognitive measures and 2 executive function tasks based on conflict. Both executive function tasks included control conditions that assessed performance in the absence of conflict. All participants performed equivalently for the cognitive measures and the control conditions of the executive function tasks, but performance diverged in the conflict conditions. In a version of the Simon task involving spatial conflict between a target cue and its position, bilinguals and musicians outperformed monolinguals, replicating earlier research with bilinguals. In a version of the Stroop task involving auditory and linguistic conflict between a word and its pitch, the musicians performed better than the other participants. Instrumentalists and vocalists did not differ on any measure. Results demonstrate that extended musical experience enhances executive control on a nonverbal spatial task, as previously shown for bilingualism, but also enhances control in a more specialized auditory task, although the effect of bilingualism did not extend to that domain.

    Simpson, Roy L

    2013-01-01

    Using the Informatics Organizing Research Model (Effken, 2003) to add context to the information gleaned from ethnographic interviews of seven chief nurse executives (CNEs) currently leading integrated delivery systems, the author concluded nurse executives can no longer depend exclusively on American Organization of Nurse Executives (AONE) competencies as they outsource their responsibility for information technology knowledge to nurse informaticians, chief information officers, and physicians. Although AONE sets out a specific list of recommended information technology competencies for system CNEs, innovative nursing practice demands a more strategic, broader level of knowledge. This broader competency centers on the reality of CNEs being charged with creating and implementing a patient-centered vision that drives health care organizations' investment in technology. A new study identifies and validates the gaps between selected CNEs' self-identified informatics competencies and those set out by AONE (Simpson, 2012).

    This exploratory study analyzes the careers of 307 supply chain executives (SCEs). Motivated by career theory, our findings create new knowledge about the educational backgrounds and career paths that lead to SCE positions. Based on an optimal matching analysis, we are able to distinguish among six...... career patterns for SCEs. They differ in terms of the individuals' previous professional experience, educational background, and the time they needed to arrive in an executive position. By characterizing the backgrounds and career paths of SCEs, we show that supply chain management (SCM) is truly a cross......-functional profession. Our findings suggest that previous staff responsibility appears to be a more important hiring criterion than extensive SCM experience. While 56% of the executives had prior staff responsibility, only 12% of the cumulated careers were actually spent inside the SCM function....

    2012-01-01

    Despite an extensive history underscoring the role of social processes and child contributions to the development of executive functions (C. Lewis & J. Carpendale, 2009; L. S. Vygotsky, 1987), research on these relations is sparse. To address this gap, 68 mother-child dyads were examined to determine whether maternal attention-directing behaviors (attention maintaining, attention redirection) and toddlers' temperament predicted executive processes during preschool (mean age = 4.5 years, SD = 0.46)-delay and conflict inhibition. Maternal attention maintaining was associated with high levels of conflict inhibition for inhibited and exuberant children, whereas attention redirection was associated with low levels of delay and conflict inhibition for inhibited children. Therefore, maternal attention-directing behaviors may enhance the development of executive functions but only for children with inhibited and exuberant temperaments. © 2012 The Authors.

This study highlights the use of the strategic technique for personal and leadership development set to explore talents, leaders and implicit abilities. Moreover, it exhibits the flexibility of self-coaching and its appropriateness for Muslim women, especially concerning self-development, which in turn influences social and institutional development. This inquiry highlights a number of practical results which emphasizes the viability and efficacy of executive coaching on personal and institutional levels as far as the making of better world for Muslim women is concerned.

  9. Execution Models for Choreographies and Cryptoprotocols

    Directory of Open Access Journals (Sweden)

    2010-02-01

    Full Text Available A choreography describes a transaction in which several principals interact. Since choreographies frequently describe business processes affecting substantial assets, we need a security infrastructure in order to implement them safely. As part of a line of work devoted to generating cryptoprotocols from choreographies, we focus here on the execution models suited to the two levels. We give a strand-style semantics for choreographies, and propose a special execution model in which choreography-level messages are faithfully delivered exactly once. We adapt this model to handle multiparty protocols in which some participants may be compromised. At level of cryptoprotocols, we use the standard Dolev-Yao execution model, with one alteration. Since many implementations use a "nonce cache" to discard multiply delivered messages, we provide a semantics for at-most-once delivery.

  10. Enhancing Writing through Strengthened Executive Function

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available We explore aspects of essay writing requiring high-level organizational capacity and executive function. The literature supports the approach that specific and focused writing-skill mastery leads to reduced anxiety and increased self-efficacy which correlates with improved writing skills. Although essay writing is a complex multi-dimensional task, two particular strategies, tree-diagram and reference methods, specifically address the organizational skills characteristic of executive function. The tree and reference methods presented in this paper address the flow of information, not content, and consequently, the methods presented in this paper apply to mathematics and English as well as to K-12 and college level.

    2013-06-01

    Increasingly recognized as an important factor in the performance of complex, goal-directed tasks, executive functioning is understood in different ways across disciplines. The aim was to explore the ways in which executive functioning is conceptualized, discussed, described, and implied in the occupational therapy literature. A scoping review of the occupational therapy literature was conducted following Levac, Colquhoun, and O'Brien's (2010) recommended methodology. Executive functioning is described both as a set of performance component skills or processes and as the executive occupational performance inherent in complex occupations. Executive functioning is implicit in occupational performance and engagement, and some health conditions seem to be commonly associated with impaired executive functioning. Assessing executive functioning requires dynamic occupation- and performance-based assessment. Interventions targeting executive functioning are grounded in metacognitive approaches. Executive functioning is a complex construct that is conceptualized with considerable variance within the occupational therapy literature, creating barriers to effective service delivery.

  13. Study of Dependencies in Executions of E-Contract Activities

    Science.gov (United States)

    Vidyasankar, K.; Krishna, P. Radha; Karlapalem, Kamalakar

    An e-contract is a contract modeled, specified, executed, controlled and monitored by a software system. A contract is a legal agreement involving parties, activities, clauses and payments. The goals of an e-contract include precise specification of the activities of the contract, mapping them into deployable workflows, and providing transactional support in their execution. Activities in a contract are generally complex and interdependent. They may be executed by different parties autonomously and in a loosely coupled fashion. They differ from database transactions in many ways: (i) Different successful executions are possible for an activity; (ii) Unsuccessful executions may be compensated or re-executed to get different results; (iii) Whether an execution is successful or not may not be known until after several subsequent activities are executed, and so it may be compensated and/or re-executed at different times relative to the execution of other activities; (iv) Compensation or re-execution of an activity may require compensation or re-execution of several other activities; etc. In this paper, we study the interdependencies between the executions of e-contract activities. This study will be helpful in monitoring behavioral conditions stated in an e-contracts during its execution.

    The current study examined an important aspect of experience--physical activity--that may contribute to children's executive function. The design attempted to tease apart 2 important aspects of children's exercise by examining the separate and combined effects of acute physical activity and cognitive engagement on an aspect of children's executive functioning. In a 2 × 2 within-subject experimental design, children (N = 33, 6 to 10 years old) completed activities that varied systematically in both physical activity (physically active video games versus sedentary video activities) and cognitive engagement (challenging and interactive video games versus repetitive video activities). Cognitive functioning, including executive function, was assessed after each activity by a modified flanker task (Rueda et al., 2004). Whereas cognitive engagement had no effect on any aspect of task performance, physical activity (i.e., exergaming) enhanced children's speed to resolve interference from conflicting visuospatial stimuli. Age comparisons indicated improvements with age in the accuracy of resolving interference and in overall response time. The results extend past research by showing more precisely how physical activity influences executive function and how this effect differs from the improvements that occur with development.

  19. Validating Avionics Conceptual Architectures with Executable Specifications

    Directory of Open Access Journals (Sweden)

    Nils Fischer

    2012-08-01

    Full Text Available Current avionics systems specifications, developed after conceptual design, have a high degree of uncertainty. Since specifications are not sufficiently validated in the early development process and no executable specification exists at aircraft level, system designers cannot evaluate the impact of their design decisions at aircraft or aircraft application level. At the end of the development process of complex systems, e. g. aircraft, an average of about 65 per cent of all specifications have to be changed because they are incorrect, incomplete or too vaguely described. In this paper, a model-based design methodology together with a virtual test environment is described that makes complex high level system specifications executable and testable during the very early levels of system design. An aircraft communication system and its system context is developed to demonstrate the proposed early validation methodology. Executable specifications for early conceptual system architectures enable system designers to couple functions, architecture elements, resources and performance parameters, often called non-functional parameters. An integrated executable specification at Early Conceptual Architecture Level is developed and used to determine the impact of different system architecture decisions on system behavior and overall performance.

    1984-01-01

    An executable assertion is a logical statement about the variables or a block of code. If there is no error during execution, the assertion statement results in a true value. Executable assertions can be used for dynamic testing of software. They can be employed for validation during the design phase, and exception and error detection during the operation phase. The present investigation is concerned with the problem of writing executable assertions, taking into account the use of assertions for testing flight software. They can be employed for validation during the design phase, and for exception handling and error detection during the operation phase The digital flight control system and the flight control software are discussed. The considered system provides autopilot and flight director modes of operation for automatic and manual control of the aircraft during all phases of flight. Attention is given to techniques for writing and using assertions to test flight software, an experimental setup to test flight software, and language features to support efficient use of assertions.

    Full Text Available Executive functions might be important for successful performance in sports, particularly in team sports requiring quick anticipation and adaptation to continuously changing situations in the field. The executive functions motor inhibition, attention and visuospatial working memory were examined in highly talented soccer players. Eighty-four highly talented youth soccer players (mean age 11.9, and forty-two age-matched amateur soccer players (mean age 11.8 in the age range 8 to 16 years performed a Stop Signal task (motor inhibition, the Attention Network Test (alerting, orienting, and executive attention and a visuospatial working memory task. The highly talented soccer players followed the talent development program of the youth academy of a professional soccer club and played at the highest national soccer competition for their age. The amateur soccer players played at a regular soccer club in the same geographical region as the highly talented soccer players and play in a regular regional soccer competition. Group differences were tested using analyses of variance. The highly talented group showed superior motor inhibition as measured by stop signal reaction time (SSRT on the Stop Signal task and a larger alerting effect on the Attention Network Test, indicating an enhanced ability to attain and maintain an alert state. No group differences were found for orienting and executive attention and visuospatial working memory. A logistic regression model with group (highly talented or amateur as dependent variable and executive function measures that significantly distinguished between groups as predictors showed that these measures differentiated highly talented soccer players from amateur soccer players with 89% accuracy. Highly talented youth soccer players outperform youth amateur players on suppressing ongoing motor responses and on the ability to attain and maintain an alert state; both may be essential for success in soccer.

  15. Unraveling Executive Functioning in Dual Diagnosis.

    Duijkers, Judith C L M; Vissers, Constance Th W M; Egger, Jos I M

    2016-01-01

    In mental health, the term dual-diagnosis is used for the co-occurrence of Substance Use Disorder (SUD) with another mental disorder. These co-occurring disorders can have a shared cause, and can cause/intensify each other's expression. Forming a threat to health and society, dual-diagnosis is associated with relapses in addiction-related behavior and a destructive lifestyle. This is due to a persistent failure to control impulses and the maintaining of inadequate self-regulatory behavior in daily life. Thus, several aspects of executive functioning like inhibitory, shifting and updating processes seem impaired in dual-diagnosis. Executive (dys-)function is currently even seen as a shared underlying key component of most mental disorders. However, the number of studies on diverse aspects of executive functioning in dual-diagnosis is limited. In the present review, a systematic overview of various aspects of executive functioning in dual-diagnosis is presented, striving for a prototypical profile of patients with dual-diagnosis. Looking at empirical results, inhibitory and shifting processes appear to be impaired for SUD combined with schizophrenia, bipolar disorder or cluster B personality disorders. Studies involving updating process tasks for dual-diagnosis were limited. More research that zooms in to the full diversity of these executive functions is needed in order to strengthen these findings. Detailed insight in the profile of strengths and weaknesses that underlies one's behavior and is related to diagnostic classifications, can lead to tailor-made assessment and indications for treatment, pointing out which aspects need attention and/or training in one's self-regulative abilities.

    The ability to recognize quickly inside network flows to be executable is prerequisite for malware detection. For this purpose, we introduce an instruction transition probability matrix (ITPX) which is comprised of the IA-32 instruction sets and reveals the characteristics of executable code's instruction transition patterns. And then, we propose a simple algorithm to detect executable code inside network flows using a reference ITPX which is learned from the known Windows Portable Executable files. We have tested the algorithm with more than thousands of executable and non-executable codes. The results show that it is very promising enough to use in real world.

    Platform virtualization helps solving major grid computing challenges: share resource with flexible, user-controlled and custom execution environments and in the meanwhile, isolate failures and malicious code. Grid resource management tools will evolve to embrace support for virtual resource. We present two open source projects that transparently supply virtual execution environments. Tycoon has been developed at HP Labs to optimise resource usage in creating an economy where users bid to access virtual machines and compete for CPU cycles. SmartDomains provides a peer-to-peer layer that automates virtual machines deployment using a description language and deployment engine from HP Labs. These projects demonstrate both client-server and peer-to-peer approaches to virtual resource management. The first case makes extensive use of virtual machines features for dynamic resource allocation. The second translates virtual machines capabilities into a sophisticated language where resource management components can b...

  6. Early executive function predicts reasoning development.

    Science.gov (United States)

    Richland, Lindsey E; Burchinal, Margaret R

    2013-01-01

    Analogical reasoning is a core cognitive skill that distinguishes humans from all other species and contributes to general fluid intelligence, creativity, and adaptive learning capacities. Yet its origins are not well understood. In the study reported here, we analyzed large-scale longitudinal data from the Study of Early Child Care and Youth Development to test predictors of growth in analogical-reasoning skill from third grade to adolescence. Our results suggest an integrative resolution to the theoretical debate regarding contributory factors arising from smaller-scale, cross-sectional experiments on analogy development. Children with greater executive-function skills (both composite and inhibitory control) and vocabulary knowledge in early elementary school displayed higher scores on a verbal analogies task at age 15 years, even after adjusting for key covariates. We posit that knowledge is a prerequisite to analogy performance, but strong executive-functioning resources during early childhood are related to long-term gains in fundamental reasoning skills.

    Full Text Available This article describes psychological challenges that executive leaders of companies face nowadays. The study of the social context is based on changes that took place with the development of information technologies. The analysis touches upon such phenomena as virtualization, involvement in the external sociocommunicative environment, and the emergence of multiple identity. It is suggested that in order to adapt to changing conditions one should follow the path of self-development—in particular, to develop attention, imagination, and willpower. In connection with the traits generally attributed to executive leaders, the article emphasizes self-adjustment; common sense as an integral part of intuition, emotions, and imagination; and the readiness to make choices in fifty-fifty situations.

    2007-03-01

    There is accumulating evidence that prefrontal systems play an important role in management of personal finances, based on studies using clinical populations, functional neuroimaging, and both subjective and objective neuropsychological measures. This study developed the Executive Personal Finance Scale (EPFS) as a specific self-rating measure of executive aspects of personal money management. The resulting 20-item scale had good reliability and showed four factors: impulse control, organization, planning, and motivational drive. Validity was evidenced by correlations with income, credit card debt, and investments. The EPFS also showed logical correlations with compulsive buying and money attitudes. Second-order factor analysis of the EPFS and other scales revealed two higher-order factors of personal finance: cognitive (e.g., planning, organizing) and emotional (e.g., anxiety, impulse-spending, prestige). The EPFS shows good psychometric properties, is easy to use, and will make a convenient complement to other research methodologies exploring the neural basis of personal finance management.

    2007-01-01

    Editors' Summary Background. Lethal injection is a common form of execution in a number of countries, most prominently the US and China. The protocols currently used in the US contain three drugs: an ultrashort-acting barbiturate, thiopental (which acts as an anesthetic, but does not have any analgesic effect); a neuromuscular blocker, pancuronium bromide (which causes muscle paralysis); and an electrolyte, potassium chloride (which stops the heart from beating). Each of these drugs on its ow...

    Light is a powerful stimulant for human alertness and cognition that can be easily administered to improve performance or counteract the negative impact of sleepiness, even during the day. Here, we show that prior exposure to longer wavelength light (orange), relative to shorter wavelength (blue), enhances the subsequent impact of light on executive brain responses. These findings emphasize the importance of light for human cognitive brain function and constitute compelling evidence in favor ...

    1990-01-01

    Due to sensor errors, uncertainty, incomplete knowledge, and a dynamic world, robot plans will not always be executed exactly as planned. This paper describes an implemented robot planning system that enhances the traditional sense-think-act cycle in ways that allow the robot system monitor its behavior and react in emergencies in real-time. A proposal on how robot systems can completely break away from the traditional three-step cycle is also made.

  14. Getting the right grasp on executive function

    Directory of Open Access Journals (Sweden)

    Claudia L R Gonzalez

    2014-04-01

    Full Text Available Executive Function (EF refers to important socio-emotional and cognitive skills that are known to be highly correlated with both academic and life success. EF is a blanket term that is considered to include self-regulation, working memory, and planning. Recent studies have shown a relationship between EF and motor control. The emergence of motor control coincides with that of EF, hence understanding the relationship between these two domains could have significant implications for early detection and remediation of later EF deficits. The purpose of the current study was to investigate this relationship in young children. This study incorporated the Behavioural Rating Inventory of Executive Function (BRIEF and two motor assessments with a focus on precision grasping to test this hypothesis. The BRIEF is comprised of two indices of EF: 1 the Behavioral Regulation Index (BRI containing three subscales: Inhibit, Shift, and Emotional Control; 2 the Metacognition Index (MI containing five subscales: Initiate, Working Memory, Plan/Organize, Organization of Materials, and Monitor. A global executive composite (GEC is derived from the two indices. In this study, right-handed children aged 5-6 and 9-10 were asked to: grasp-to-construct (Lego® models; and grasp-to-place (wooden blocks, while their parents completed the BRIEF questionnaire. Analysis of results indicated significant correlations between the strength of right hand preference for grasping and numerous elements of the BRIEF including the BRI, MI, and GEC. Specifically, the more the right hand was used for grasping the better the EF ratings. In addition, patterns of space-use correlated with the GEC in several subscales of the BRIEF. Finally and remarkably, the results also showed a reciprocal relationship between hand and space use for grasping and EF. These findings are discussed with respect to: 1 the developmental overlap of motor and executive functions; 2 detection of EF deficits through

  15. Cognitive programs: Software for attention's executive

    Directory of Open Access Journals (Sweden)

    John K Tsotsos

    2014-11-01

    Full Text Available What are the computational tasks that an executive controller for visual attention must solve? This question is posed in the context of the Selective Tuning model of attention. The range of required computations go beyond top-down bias signals or region-of-interest determinations, and must deal with overt and covert fixations, process timing and synchronization, information routing, memory, matching control to task, spatial localization, priming, and coordination of bottom-up with top-down information. During task execution, results must be monitored to ensure the expected results. This description includes the kinds of elements that are common in the control of any kind of complex machine or system. We seek a mechanistic integration of the above, in other words, algorithms that accomplish control. Such algorithms operate on representations, transforming a representation of one kind into another, which then forms the input to yet another algorithm. Cognitive Programs (CPs are hypothesized to capture exactly such representational transformations via stepwise sequences of operations. CPs, an updated and modernized offspring of Ullman's Visual Routines, impose an algorithmic structure to the set of attentional functions and play a role in the overall shaping of attentional modulation of the visual system so that it provides its best performance. This requires that we consider the visual system as a dynamic, yet general-purpose processor tuned to the task and input of the moment. This differs dramatically from the almost universal cognitive and computational views, which regard vision as a passively observing module to which simple questions about percepts can be posed, regardless of task. Differing from Visual Routines, CPs explicitly involve the critical elements of Visual Task Executive, Visual Attention Executive, and Visual Working Memory. Cognitive Programs provide the software that directs the actions of the Selective Tuning model of visual

    2008-06-01

    Depression in the elderly is frequently accompanied by cognitive impairment. Executive dysfunction, including disturbances in planning, sequencing, organizing and abstracting has been reported in late-onset depression. They were found to be associated with relapse and recurrence of geriatric major depression and with residual depressive symptoms. A group of patients with late-onset depression, compared with age matched healthy volunteers, were assessed for deficits in executive functioning. We used the computer version of Stroop Color-Word test enabling more detailed reaction time analysis. Severity of depression was evaluated with Hamilton depression rating scale and Geriatric depression scale. The preliminary results of a study show that patients with late-onset depression have increased absolute reaction times in Stroop colour-word test. Significant differences in the magnitude of individual interference effects pointing towards a characteristic change in attentional processes in depressed patients. The preliminary results of a study comparing a group of elderly depressed patients with a control group of older healthy volunteers confirm changes in executive functions.

    Barry, D R; O'Leary, D S; Labovitz, G; Harper, D L; Sennett, C; Lord, J T; Jones, J J; Wright, J

    1997-01-01

    In the last issue of Healthcare Executive, we introduced the first in a two-part series on quality in healthcare. The series, which is predicated on a five-hour roundtable discussion among eight healthcare leaders, was moderated by Thomas C. Dolan, Ph.D., FACHE, CAE, ACHE's president and chief executive officer, and jointly sponsored by ACHE and the Bayer Quality Network, an educational forum for sharing innovative and effective continuous quality improvement methods with healthcare executives. In Part I, participants spoke about current issues as they relate to quality. They discussed the reliability of existing quality data and expressed a need for more practical indicators and measurement systems. The consumer mindset was discussed, as leaders debated the value of customer satisfaction surveys and ways to create more realistic consumer expectations. In terms of employers and third parties, participants suggested tailoring quality information and presenting it in a simplified fashion. Finally, leaders emphasized the need for better performance information, as well as the use of outcomes data for both educational and quality improvement purposes. In Part II, the dialogue remains compelling. Participants cover new ground as they talk about the role of accreditors in regulating quality, of governance teams and senior management in creating an organizational culture to support quality, and of physicians in attracting both business partners and patients based on quality. Following is the second in our two-part series.

  6. Can Rhesus Monkey Learn Executive Attention?

    Directory of Open Access Journals (Sweden)

    Jessica Bramlett-Parker

    2016-06-01

    Full Text Available A growing body of data indicates that, compared to humans, rhesus monkeys perform poorly on tasks that assess executive attention, or voluntary control over selection for processing, particularly under circumstances in which attention is attracted elsewhere by competing stimulus control. In the human-cognition literature, there are hotly active debates about whether various competencies such as executive attention, working memory capacity, and fluid intelligence can be improved through training. In the current study, rhesus monkeys (Macaca mulatta completed an attention-training intervention including several inhibitory-control tasks (a Simon task, numerical Stroop task, global/local interference task, and a continuous performance task to determine whether generalized improvements would be observed on a version of the Attention Network Test (ANT of controlled attention, which was administered before and after the training intervention. Although the animals demonstrated inhibition of prepotent responses and improved in executive attention with practice, this improvement did not generalize to the ANT at levels consistently better than were observed for control animals. Although these findings fail to encourage the possibility that species differences in cognitive competencies can be ameliorated through training, they do advance our understanding of the competition between stimulus-control and cognitive-control in performance by nonhuman and human primates.

  11. Executive compensation and firm performance: Evidence from Indian firms

    Directory of Open Access Journals (Sweden)

    Mehul Raithatha

    2016-09-01

    Full Text Available The study examines the relationship between executive compensation and firm performance among Indian firms. The evidence suggests that firm performance measured by accounting, as well as market-based measures, significantly affects executive compensation. We also test for the presence of persistence in executive compensation by employing the system-generalised methods of moments (GMM estimator. We find significant persistence in executive compensation among the sample firms. Further, we report the absence of pay–performance relationship among the smaller sample firms and business group affiliated firms. Thus, our findings cast doubts over the performance-based executive compensation practices of Indian business group affiliated firms.

    2005-01-01

    Many traditional planners are built on top of existing execution engines that were not necessarily intended to be operated by a planner. The Mission Data System has been designed from the onset to have both an execution and planning engine and provides a framework for producing state-based models that can be used to coordinate planning and execution. The models provide a basis for ensuring the consistency of assumptions made by the execution engine and planner, and the frameworks provide a basis for run time communications between the planner and execution engines.

  13. Nurse executive transformational leadership found in participative organizations.

    Science.gov (United States)

    Dunham-Taylor, J

    2000-05-01

    The study examined a national sample of 396 randomly selected hospital nurse executives to explore transformational leadership, stage of power, and organizational climate. Results from a few nurse executive studies have found nurse executives were transformational leaders. As executives were more transformational, they achieved better staff satisfaction and higher work group effectiveness. This study integrates Bass' transformational leadership model with Hagberg's power stage theory and Likert's organizational climate theory. Nurse executives (396) and staff reporting to them (1,115) rated the nurse executives' leadership style, staff extra effort, staff satisfaction, and work group effectiveness using Bass and Avolio's Multifactor Leadership Questionnaire. Executives' bosses (360) rated executive work group effectiveness. Executives completed Hagberg's Personal Power Profile and ranked their organizational climate using Likert's Profile of Organizational Characteristics. Nurse executives used transformational leadership fairly often; achieved fairly satisfied staff levels; were very effective according to bosses; were most likely at stage 3 (power by achievement) or stage 4 (power by reflection); and rated their hospital as a Likert System 3 Consultative Organization. Staff satisfaction and work group effectiveness decreased as nurse executives were more transactional. Higher transformational scores tended to occur with higher educational degrees and within more participative organizations. Transformational qualities can be enhanced by further education, by achieving higher power stages, and by being within more participative organizations.

  14. Executive functioning: a conceptual framework for alcohol-related aggression.

    Science.gov (United States)

    Giancola, P R

    2000-11-01

    The causal mechanisms underlying alcohol-related aggression are not well understood. This article presents a conceptual framework designed to guide thinking and generate new research in this area of study. According to the framework, executive functioning is both a mediator and a moderator of intoxicated aggression. Literatures describing associations between alcohol and aggression, executive functioning and aggression, and the acute effects of alcohol on executive functioning are reviewed. On the basis of these findings, it is proposed that (a) executive functioning mediates the alcohol-aggression relation in that acute alcohol intoxication disrupts executive functioning, which then heightens the probability of aggression, and (b) executive functioning moderates the alcohol-aggression relation in that acute alcohol consumption is more likely to facilitate aggressive behavior in persons with low, rather than high, executive functioning.

  15. Global view offers good news for physician executives.

    Science.gov (United States)

    Lyons, M F

    1998-01-01

    Do all physician executives have much "catching up" to do in relation to their non-MD colleagues? A comparison of the role of the physician executive versus the non-MD executive/administrator provides a big picture view and signals new opportunities for physicians in the evolving health care system. Physician executives have only recently become invested in the health care executive suite and are less wedded to old methods and "classic" ideas. They are more likely to be able to adapt to new circumstances, jettisoning traditional approaches that have outlived their usefulness. But each group-physician executives and their MHA- or MBA-credentialed, non-MD colleagues- has much to offer to or learn from the other. By retaining those skills that are applicable, while also adapting the useful characteristics of the "traditional" health care administrator, a physician executive can increase the likelihood of success today.

    2017-07-14

    The executive functions of the homeless may be contributing to the success or failure of social integration processes. The goal of this study was to analyze the relationship between attachment and executive dysfunction in the homeless, specifically, to analyze the prevalence of adult attachment and executive dysfunction patterns, as well as the predictive power of different types of attachment for executive functioning. Participants were 107 homeless. Descriptive analysis revealed the prevalence of insecure attachment, and a high prevalence of clinically significant executive dysfunction. Regression analysis showed that attachment predicts all the executive functions, although the predictive power of attachment decreased when entering the variable drug addiction. People in a situation of chronic social exclusion are characterized by an insecure attachment style and moderate levels of executive dysfunction.

  17. An empirical analysis of executive behaviour with hospital executive information systems in Taiwan.

    Science.gov (United States)

    Huang, Wei-Min

    2013-01-01

    Existing health information systems largely only support the daily operations of a medical centre, and are unable to generate the information required by executives for decision-making. Building on past research concerning information retrieval behaviour and learning through mental models, this study examines the use of information systems by hospital executives in medical centres. It uses a structural equation model to help find ways hospital executives might use information systems more effectively. The results show that computer self-efficacy directly affects the maintenance of mental models, and that system characteristics directly impact learning styles and information retrieval behaviour. Other results include the significant impact of perceived environmental uncertainty on scan searches; information retrieval behaviour and focused searches on mental models and perceived efficiency; scan searches on mental model building; learning styles and model building on perceived efficiency; and finally the impact of mental model maintenance on perceived efficiency and effectiveness.

    Full Text Available Orientation: The evaluation of training programmes provides methodological and logistical challenges to evaluators and human resource (HR managers. The training of executive coaches is no exception in this regard. Research purpose: The study aimed to investigate one particular aspect of the results of an executive coach training programme, and the extent to which knowledge, skills and attitudes acquired during the programme were applied in practical settings.Motivation for the study: Too little is known in South Africa about the effectiveness of training programmes, including executive coach training programmes. There is a need to demonstrate methodological approaches that would provide valid and reliable data.Research design, approach and method: The success case method (SCM was used to guide the study, consisting first of a survey of 80 participants in the training programme, followed by eight interviews to compare successful with less successful cases of skills transfer.Main findings: All six successful coaches were applying the proximal outcomes from the training with good results, with several valuable consequences resulting from the training. Barriers to successful implementation included personal circumstances and unfulfilled expectations of the programme content.Practical/managerial implications: Aspects of the training programme that could be improved included: the buddy selection system, more individualised feedback about self-development, closer supervision, and more support from programme managers.Contribution/value-add: This evaluation contributes to the evaluation literature by providing a documented exploration of a systematic application of the SCM. It also contributes to the coach training literature by providing a systematic evaluation of a coach training intervention in South Africa.

  19. Evidence of dopaminergic processing of executive inhibition.

    Directory of Open Access Journals (Sweden)

    Rajendra D Badgaiyan

    Full Text Available Inhibition of unwanted response is an important function of the executive system. Since the inhibitory system is impaired in patients with dysregulated dopamine system, we examined dopamine neurotransmission in the human brain during processing of a task of executive inhibition. The experiment used a recently developed dynamic molecular imaging technique to detect and map dopamine released during performance of a modified Eriksen's flanker task. In this study, young healthy volunteers received an intravenous injection of a dopamine receptor ligand ((11C-raclopride after they were positioned in the PET camera. After the injection, volunteers performed the flanker task under Congruent and Incongruent conditions in a single scan session. They were required to inhibit competing options to select an appropriate response in the Incongruent but not in the Congruent condition. The PET data were dynamically acquired during the experiment and analyzed using two variants of the simplified reference region model. The analysis included estimation of a number of receptor kinetic parameters before and after initiation of the Incongruent condition. We found increase in the rate of ligand displacement (from receptor sites and decrease in the ligand binding potential in the Incongruent condition, suggesting dopamine release during task performance. These changes were observed in small areas of the putamen and caudate bilaterally but were most significant on the dorsal aspect of the body of left caudate. The results provide evidence of dopaminergic processing of executive inhibition and demonstrate that neurochemical changes associated with cognitive processing can be detected and mapped in a single scan session using dynamic molecular imaging.

    Full Text Available This article starts with a literary review of the conceptual frames through which esport has been labeled academically. It shows how the concept of “electronic” has been taken as the core term for labelingesport, often accompanied by a strong emphasis on “professionalism.” The literary review is followed by the submission of an alternative conceptual frame based on the economic notion of executive ownership, which provides a theoretical grounding for esport as a cultural phenomenon. In accordance with the above, the article concludes with a reframed look at the history of esport and suggests commercial analog gaming (especially Magic: The Gathering as its point of origin.

    Muller, H J; Smith, H L

    1985-01-01

    Retrenchment is a problem confronting many public, private, and voluntary healthcare organizations. With budgetary restrictions in the public sector and the shift toward prospective payment systems and diagnosis-related reimbursement by third-party payors, healthcare executives must address several dilemmas and choices. Yet, retrenchment should not necessarily be viewed as a problem with limited alternatives. It may represent a time for capitalizing on opportunities and for creating innovation within healthcare institutions. Indeed, innovation may represent the only means for survival. This article evaluates the management strategies that transform retrenchment from a problem into an opportunity.

Investigating the association between executive functioning, repetitive thinking, and depressive mood, the present study empirically tested this mediational model in a sample of older adults, while focusing on both concrete and abstract repetitive thinking. This latter distinction is important given the potential protective role of concrete repetitive thinking, in contrast to the depletive effect of abstract repetitive thinking. A sample of 43 elderly volunteers, between 75 and 95 years of age, completed tests of executive functioning (the Stroop test, the Trail Making test, and the Fluency test), and questionnaires of repetitive thinking and depression. Positive correlations were observed between abstract repetitive thinking and depressive mood, and between concrete repetitive thinking and executive functioning; a negative correlation was observed between depressive mood and executive functioning. Further, mediational analysis evidenced that the relation between executive functioning and depressive mood was mediated by abstract repetitive thinking. The present data provide, for the first time, empirical support to the depressive-executive dysfunction hypothesis: the lack of executive resources would favor a mode of abstract repetitive thinking, which in turn would deplete mood. It suggests that clinical intervention targeting depression in the elderly should take into consideration repetitive thinking modes and the executive resources needed to disengage from rumination.

  7. Rehabilitation of executive functions: Implications and strategies

    Full Text Available Executive Functions (EF concern a range of abilities including problem-solving, planning, initiation, selfmonitoring,conscious attention, cope with new situations and the ability to modify plans if necessary. It’s a high cognitive function that is crucial for a person to get engaged and maintain daily activities whilst keeping a good quality of life. Problems in the EF were formerly known as Dysexecutive Syndrome (DS. There are many models concerning DS, although the literature on the subject still remains unclear. Several works appoint the effects brought by elderly life, as well as abuse of drugs and some psychopathologies. These factors are known to increase the distress of the frontal circuits and that could be associated to executive deficits. The effects of DS would compromise individuals in day-to-day routine, academic, social and labor fields. There is a growing body of studies trying to determine the causes, implications, associations and the best way to take care of these effects. This work intends to review DS, focusing on the most important fields related to this area, such as psychopathology associations, cognitive reserve, assessment and cognitive rehabilitation programs.

    We describe the current state-of-the-art in Trusted Computing Technologies - focusing mainly on Intel's Trusted Execution Technology (TXT). This document is based on existing documentation and tests of two existing TXT-based systems: Intel's Trusted Boot and Invisible Things Lab's Qubes OS. We describe what features are lacking in current implementations, describe what a mature system could provide, and present a list of developments to watch. Critical systems perform operation-critical computations on high importance data. In such systems, the inputs, computation steps, and outputs may be highly sensitive. Sensitive components must be protected from both unauthorized release, and unauthorized alteration: Unauthorized users should not access the sensitive input and sensitive output data, nor be able to alter them; the computation contains intermediate data with the same requirements, and executes algorithms that the unauthorized should not be able to know or alter. Due to various system requirements, such critical systems are frequently built from commercial hardware, employ commercial software, and require network access. These hardware, software, and network system components increase the risk that sensitive input data, computation, and output data may be compromised.

  9. The Executive Control of Face Memory

    Directory of Open Access Journals (Sweden)

    Steven Z. Rapcsak

    2011-01-01

    Full Text Available Patients with frontal lobe damage and cognitively normal elderly individuals demonstrate increased susceptibility to false facial recognition. In this paper we review neuropsychological evidence consistent with the notion that the common functional impairment underlying face memory distortions in both subject populations is a context recollection/source monitoring deficit, coupled with excessive reliance on relatively preserved facial familiarity signals in recognition decisions. In particular, we suggest that due to the breakdown of strategic memory retrieval, monitoring, and decision operations, individuals with frontal lobe impairment caused by focal damage or age-related functional decline do not have a reliable mechanism for attributing the experience of familiarity to the correct context or source. Memory illusions are mostly apparent under conditions of uncertainty when the face cue does not directly elicit relevant identity-specific contextual information, leaving the source of familiarity unspecified or ambiguous. Based on these findings, we propose that remembering faces is a constructive process that requires dynamic interactions between temporal lobe memory systems that operate in an automatic or bottom-up fashion and frontal executive systems that provide strategic top-down control of recollection. Executive memory control functions implemented by prefrontal cortex play a critical role in suppressing false facial recognition and related source memory misattributions.

    García-Molina, Alberto; Tirapu-Ustárroz, Javier; Luna-Lario, Pilar; Ibáñez, Joaquín; Duque, Pablo

    2010-06-16

    With the growth of cognitive science, the study of the cognitive components involved in solving tests to assess intelligence become especially significant. From this perspective, the g factor is conceived as the representative of the operation of high-level cognitive processes that control the computational programmes of the brain. Different names have been used to denominate the cognitive processes that underlie the g factor: control processes, executive functioning, executive control or executive functions. We review the relationship between intelligence, on the one hand, and working memory and the executive functions construct, on the other. Furthermore, the article also reviews the relationship between intelligence and the prefrontal cortex, as its possible neuroanatomical substrate. The studies that were surveyed offer different answers to the question of whether intelligence and the executive functions are one and the same thing, the most widely accepted hypothesis being the one that sees intelligence and the executive functions as overlapping in some aspects but not in others.

  13. Dysfunctional Metacognitive Beliefs Are Associated with Decreased Executive Control

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available Dysfunctional metacognitive beliefs (“metacognitions” and executive control are important factors in mental disorders such as depression and anxiety, but the relationship between these concepts has not been studied systematically. We examined whether there is an association between metacognitions and executive control and hypothesized that decreased executive control statistically predicts increased levels of metacognitions. Two hundred and ninety-nine individuals recruited from the general population and outpatient psychiatric clinics completed the Metacognitions Questionnaire-30 and three subtests from the Cambridge Neuropsychological Test Automated Battery corresponding to the three-component model of executive functions. Controlling for current depression and anxiety symptoms, decreased ability to shift between mental sets was associated with increased negative beliefs about the uncontrollability and danger of worry and beliefs about the need to control thoughts. The results suggest a basic association between metacognitions and executive control. Individual differences in executive control could prove important in the personalization of metacognitive therapy.

    This report presents the implementation of a stateless scheme for Faithful Execution, the design for which is presented in a companion report, ''Principles of Faithful Execution in the Implementation of Trusted Objects'' (SAND 2003-2328). We added a simple cryptographic capability to an already simplified class loader and its associated Java Virtual Machine (JVM) to provide a byte-level implementation of Faithful Execution. The extended class loader and JVM we refer to collectively as the Sandia Faithfully Executing Java architecture (or JavaFE for short). This prototype is intended to enable exploration of more sophisticated techniques which we intend to implement in hardware.

    2016-08-01

    Performing Failure Modes and Effect Analysis (FMEA) during software architecture design is becoming a basic requirement in an increasing number of domains; however, due to the lack of standardized early design phase model execution, classic SW-FMEA approaches carry significant risks and are human effort-intensive even in processes that use Model-Driven Engineering.Recently, modelling languages with standardized executable semantics have emerged. Building on earlier results, this paper describes framework support for generating executable error propagation models from such models during software architecture design. The approach carries the promise of increased precision, decreased risk and more automated execution for SW-FMEA during dependability- critical system development.

    Current standardized neuropsychological tests may fail to accurately capture real-world executive deficits. We developed a computer-based Cooking Task (CT) assessment of executive functions and trialed the measure with a normative group before use with a head-injured population. Forty-six participants completed the computerized CT and subtests from standardized neuropsychological tasks, including the Tower and Sorting Tests of executive function from the Delis-Kaplan Executive Function System (D-KEFS) and the Cambridge prospective memory test (CAMPROMPT), in order to examine whether standardized executive function tasks, predicted performance on measurement indices from the CT. Findings showed that verbal comprehension, rule detection and prospective memory contributed to measures of prospective planning accuracy and strategy implementation of the CT. Results also showed that functions necessary for cooking efficacy differ as an effect of task demands (difficulty levels). Performance on rule detection, strategy implementation and flexible thinking executive function measures contributed to accuracy on the CT. These findings raise questions about the functions captured by present standardized tasks particularly at varying levels of difficulty and during dual-task performance. Our preliminary findings also indicate that CT measures can effectively distinguish between executive function and Full Scale IQ abilities. Results of the present study indicate that the CT shows promise as an ecologically valid measure of executive function for future use with a head-injured population and indexes selective executive function’s captured by standardized tests.

    2013-01-01

    Future NASA plans call for long-duration deep space missions with human crews. Because of light-time delay and other considerations, increased autonomy will be needed. This will necessitate integration of tools in such areas as anomaly detection, diagnosis, planning, and execution. In this paper we investigate an approach that integrates planning and execution by embedding planner-derived temporal constraints in an execution procedure. To avoid the need for propagation, we convert the temporal constraints to dispatchable form. We handle some uncertainty in the durations without it affecting the execution; larger variations may cause activities to be skipped.

    We present a semantics for the statechart variant implemented in the Statemate product of i-Logix. Our semantics enables distributed code generation for Statemate models in the context of rapid prototyping for embedded control applications. We argue that it seems impossible to efficiently generate...... distributed code using the original Statemate semantics. The new, distributed semantics has the advantages that, first, it enables the generation of efficient distributed code, second, it preserves many aspects of the original semantics for those parts of a model that are not distributed, and third......, the changes made regarding the interaction of distributed model parts are similar to the interaction between the model and its environment in the original semantics, thus giving designers a familiar execution model. The semantics has been implemented in Grace, a framework for rapid prototyping code generation...

    2004-11-01

    The primary goal of this investigation was to determine whether executive functioning (EF) would moderate the alcohol-aggression relation. Participants were 310 (152 men and 158 women) healthy social drinkers between 21 and 35 years of age. EF as well as non-EF skills were measured with 13 validated neuropsychological tests. Following the consumption of either an alcoholic or a placebo beverage, participants were tested on a modified version of the Taylor Aggression Paradigm (S. Taylor, 1967), in which mild electric shocks were received from, and administered to, a fictitious opponent. Aggressive behavior was operationalized as the shock intensities administered to the fictitious opponent. EF was negatively related to aggressive behavior for men, regardless of beverage group, even when controlling for non-EF skills. Furthermore, alcohol increased aggression only for men with lower EF scores. Finally, the mere belief that alcohol was consumed suppressed aggression for women but not for men. Copyright 2004 APA.

  6. The Development of Executive Function in Autism

    2012-01-01

    Full Text Available Autism is a common and often highly debilitating neurodevelopmental condition, whose core behavioral features are believed to be rooted in disrupted neurocognitive processes, including especially “executive function.” Researchers have predominantly focused upon understanding the putative causal relationship between difficulties in EF and autistic symptomatology. This paper suggests, however, that the effects of individual differences in EF should be more far-reaching, playing a significant part in the real-life outcomes of individuals with autism, including their social competence, everyday adaptive behavior, and academic achievement. It further considers the nature of the EF-outcome relationship, including the possible determinants of individual differences in EF, and makes several recommendations for future research.

  7. A Brokering Solution for Business Process Execution

    Predicting the climate change impact on biodiversity and ecosystems, advancing our knowledge of environmental phenomena interconnection, assessing the validity of simulations and other key challenges of Earth Sciences require intensive use of environmental modeling. The complexity of Earth system requires the use of more than one model (often from different disciplines) to represent complex processes. The identification of appropriate mechanisms for reuse, chaining and composition of environmental models is considered a key enabler for an effective uptake of a global Earth Observation infrastructure, currently pursued by the international geospatial research community. The Group on Earth Observation (GEO) Model Web initiative aims to increase present accessibility and interoperability of environmental models, allowing their flexible composition into complex Business Processes (BPs). A few, basic principles are at the base of the Model Web concept (Nativi, et al.): 1. Open access 2. Minimal entry-barriers 3. Service-driven approach 4. Scalability In this work we propose an architectural solution aiming to contribute to the Model Web vision. This solution applies the Brokering approach for facilitiating complex multidisciplinary interoperability. The Brokering approach is currently adopted in the new GEOSS Common Infrastructure (GCI) as was presented at the last GEO Plenary meeting in Istanbul, November 2011. According to the Brokering principles, the designed system is flexible enough to support the use of multiple BP design (visual) tools, heterogeneous Web interfaces for model execution (e.g. OGC WPS, WSDL, etc.), and different Workflow engines. We designed and prototyped a component called BP Broker that is able to: (i) read an abstract BP, (ii) "compile" the abstract BP into an executable one (eBP) - in this phase the BP Broker might also provide recommendations for incomplete BPs and parameter mismatch resolution - and (iii) finally execute the eBP using a

    e-Health is here to stay and experts predict that the Internet will become the hub of health care. Rapid advancements in biotechnology and medical research, increasingly curious patients who surf the Internet for medical information, and pressures from managed care companies to contain costs and speed treatments are the central components driving e-health. Despite physician reluctance to embrace the e-revolution, many hospitals and medical groups are employing the Internet and information technology to improve their customer interface, as well as to reduce business costs. This article offers seven e-strategies for health care performance improvement: (1) Supply chain management; (2) e-transactions; (3) care management; (4) improving quality; (5) boosting revenues; (6) outsourcing; and (7) provider networks (Intranets). By helping to incorporate these key e-solutions, physician executives can position their organizations for success in the new millennium.

  14. Execution-Based Model Checking of Interrupt-Based Systems

    Science.gov (United States)

    Drusinsky, Doron; Havelund, Klaus

    2003-01-01

    Execution-based model checking (EMC) is a verification technique based on executing a multi-threaded/multiprocess program repeatedly in a systematic manner in order to explore the different interleavings of the program. This is in contrast to traditional model checking, where a model of a system is analyzed Several execution-based model-checking tools exist at this point, such as for example Verisoft and Java PathFinder. The most common formal specification languages used by EMC tools are un- timed, either just assertions, or linear-time temporal logic (LTL). An alternative verification technique is Runtime Execution Monitoring (REM), which is based on monitor- ing the execution of a program, checking that the execution trace conforms to a requirement specification. The Temporal Rover and DBRover are such tools. They provide a very rich specification language, being an extension of LTL with real-time constraints and time-series. We show how execution-based model checking, combined with runtime execution monitoring, can be used for the verification of a large class of safety critical systems commonly known as interrupt-based systems. The proposed approach is novel in that: (i) it supports model checking of a large class of applications not practically verifiable using conventional EMC tools, (ii) it supports verification of LTL assertions extended with real-time and time-series constraints, and (iii) it supports the verification of custom schedulers.

    2014-03-01

    The current study tested the resource allocation hypothesis, examining whether baseline rumination or depressive symptom levels prospectively predicted deficits in executive functioning in an adolescent sample. The alternative to this hypothesis was also evaluated by testing whether lower initial levels of executive functioning predicted increases in rumination or depressive symptoms at follow-up. A community sample of 200 adolescents (ages 12-13) completed measures of depressive symptoms, rumination, and executive functioning at baseline and at a follow-up session approximately 15 months later. Adolescents with higher levels of baseline rumination displayed decreases in selective attention and attentional switching at follow-up. Rumination did not predict changes in working memory or sustained and divided attention. Depressive symptoms were not found to predict significant changes in executive functioning scores at follow-up. Baseline executive functioning was not associated with change in rumination or depression over time. Findings partially support the resource allocation hypothesis that engaging in ruminative thoughts consumes cognitive resources that would otherwise be allocated towards difficult tests of executive functioning. Support was not found for the alternative hypothesis that lower levels of initial executive functioning would predict increased rumination or depressive symptoms at follow-up. Our study is the first to find support for the resource allocation hypothesis using a longitudinal design and an adolescent sample. Findings highlight the potentially detrimental effects of rumination on executive functioning during early adolescence. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2018-01-01

    Delays in the development of executive functioning skills are frequently observed in pediatric neuropsychology populations and can have a broad and significant impact on quality of life. As a result, assessment of executive functioning is often relevant for the development of formulations and recommendations in pediatric neuropsychology clinical work. Questionnaire-based measures of executive functioning behaviors in everyday life have unique advantages and complement traditional neuropsychological measures of executive functioning. Two case studies of children with spina bifida are presented to illustrate the clinical use of a new questionnaire measure of executive and learning-related functioning, the Learning, Executive, and Attention Functioning Scale (LEAF). The LEAF emphasizes clinical utility in assessment by incorporating four characteristics: brevity in administration, breadth of additional relevant content, efficiency of scoring and interpretation, and ease of availability for use. LEAF results were consistent with another executive functioning checklist in documenting everyday behavior problems related to working memory, planning, and organization while offering additional breadth of assessment of domains such as attention, processing speed, and novel problem-solving. These case study results demonstrate the clinical utility of questionnaire-based measurement of executive functioning in pediatric neuropsychology and provide a new measure for accomplishing this goal.

    1989-12-01

    Executives were surveyed about their hearing health-care practices and attitudes toward hearing loss (N = 140, mean age = 49, number of males = 133). In regard to hearing health-care practices, about one-third of the executives had not had a hearing test during the past 5 years. Fifty-one percent of the executives reported that a hearing test was conducted or recommended during their annual physical examinations. Twenty (14%) of the executives rated their hearing as fair or poor, but only two of them wore hearing aids. Executives who reported poorer hearing were less likely to have had recent hearing tests. When seeking a hearing evaluation, the executives indicated a two-to-one preference for medical doctors over audiologists--none preferred hearing aid dispensers. Regarding attitudes, approximately 90% of the executives felt that hearing aids were effective, but only two-thirds disagreed with the stereotype that hearing aids connote old age. Executives who tended to equate hearing aids with old age were less likely to be aware of hearing-impaired employees in their companies. Implications of these findings are discussed.

    2017-10-01

    Full Text Available Objective: This article will address how anomalies of executive function after traumatic brain injury (TBI can translate into altered social behavior that has an impact on a person’s capacity to live safely and independently in the community.Method: Review of literature on executive and neurobehavioral function linked to cognitive ageing in neurologically healthy populations and late neurocognitive effects of serious TBI. Information was collated from internet searches involving MEDLINE, PubMed, PyscINFO and Google Scholar as well as the authors’ own catalogs.Conclusions: The conventional distinction between cognitive and emotional-behavioral sequelae of TBI is shown to be superficial in the light of increasing evidence that executive skills are critical for integrating and appraising environmental events in terms of cognitive, emotional and social significance. This is undertaken through multiple fronto-subcortical pathways within which it is possible to identify a predominantly dorsolateral network that subserves executive control of attention and cognition (so-called cold executive processes and orbito-frontal/ventro-medial pathways that underpin the hot executive skills that drive much of behavior in daily life. TBI frequently involves disruption to both sets of executive functions but research is increasingly demonstrating the role of hot executive deficits underpinning a wide range of neurobehavioral disorders that compromise relationships, functional independence and mental capacity in daily life.

  14. Interaction between non-executive and executive directors in English National Health Service trust boards: an observational study.

    2015-10-15

    National Health Service (NHS) trusts, which provide the majority of hospital and community health services to the English NHS, are increasingly adopting a 'public firm' model with a board consisting of executive directors who are trust employees and external non-executives chosen for their experience in a range of areas such as finance, health care and management. In this paper we compare the non-executive directors' roles and interests in, and contributions to, NHS trust boards' governance activities with those of executive directors; and examine non-executive directors' approach to their role in board meetings. Non-participant observations of three successive trust board meetings in eight NHS trusts (primary care trusts, foundation trusts and self-governing (non-foundation) trusts) in England in 2008-9. The observational data were analysed inductively to yield categories of behaviour reflecting the perlocutionary types of intervention which non-executive directors made in trust meetings. The observational data revealed six main perlocutionary types of questioning tactic used by non-executive directors to executive directors: supportive; lesson-seeking; diagnostic; options assessment; strategy seeking; and requesting further work. Non-executive board members' behaviours in holding the executive team to account at board meetings were variable. Non-executive directors were likely to contribute to finance-related discussions which suggests that they did see financial challenge as a key component of their role. The pattern of behaviours was more indicative of an active, strategic approach to governance than of passive monitoring or 'rubber-stamping'. Nevertheless, additional means of maintaining public accountability of NHS trusts may also be required.

    Nüst, Daniel

    2017-04-01

    From generation through analysis and collaboration to communication, scientific research requires the right tools. Scientists create their own software using third party libraries and platforms. Cloud computing, Open Science, public data infrastructures, and Open Source enable scientists with unprecedented opportunites, nowadays often in a field "Computational X" (e.g. computational seismology) or X-informatics (e.g. geoinformatics) [0]. This increases complexity and generates more innovation, e.g. Environmental Research Infrastructures (environmental RIs [1]). Researchers in Computational X write their software relying on both source code (e.g. from https://github.com) and binary libraries (e.g. from package managers such as APT, https://wiki.debian.org/Apt, or CRAN, https://cran.r-project.org/). They download data from domain specific (cf. https://re3data.org) or generic (e.g. https://zenodo.org) data repositories, and deploy computations remotely (e.g. European Open Science Cloud). The results themselves are archived, given persistent identifiers, connected to other works (e.g. using https://orcid.org/), and listed in metadata catalogues. A single researcher, intentionally or not, interacts with all sub-systems of RIs: data acquisition, data access, data processing, data curation, and community support [3]. To preserve computational research [3] proposes the Executable Research Compendium (ERC), a container format closing the gap of dependency preservation by encapsulating the runtime environment. ERCs and RIs can be integrated for different uses: (i) Coherence: ERC services validate completeness, integrity and results (ii) Metadata: ERCs connect the different parts of a piece of research and faciliate discovery (iii) Exchange and Preservation: ERC as usable building blocks are the shared and archived entity (iv) Self-consistency: ERCs remove dependence on ephemeral sources (v) Execution: ERC services create and execute a packaged analysis but integrate with

  16. Disentangling motor execution from motor imagery with the phantom limb.

    Raffin, Estelle; Mattout, Jérémie; Reilly, Karen T; Giraux, Pascal

    2012-02-01

    Amputees can move their phantom limb at will. These 'movements without movements' have generally been considered as motor imagery rather than motor execution, but amputees can in fact perform both executed and imagined movements with their phantom and they report distinct perceptions during each task. Behavioural evidence for this dual ability comes from the fact that executed movements are associated with stump muscle contractions whereas imagined movements are not, and that phantom executed movements are slower than intact hand executed movements whereas the speed of imagined movements is identical for both hands. Since neither execution nor imagination produces any visible movement, we hypothesized that the perceptual difference between these two motor tasks relies on the activation of distinct cerebral networks. Using functional magnetic resonance imaging and changes in functional connectivity (dynamic causal modelling), we examined the activity associated with imagined and executed movements of the intact and phantom hands of 14 upper-limb amputees. Distinct but partially overlapping cerebral networks were active during both executed and imagined phantom limb movements (both performed at the same speed). A region of interest analysis revealed a 'switch' between execution and imagination; during execution there was more activity in the primary somatosensory cortex, the primary motor cortex and the anterior lobe of the cerebellum, while during imagination there was more activity in the parietal and occipital lobes, and the posterior lobe of the cerebellum. In overlapping areas, task-related differences were detected in the location of activation peaks. The dynamic causal modelling analysis further confirmed the presence of a clear neurophysiological distinction between imagination and execution, as motor imagery and motor execution had opposite effects on the supplementary motor area-primary motor cortex network. This is the first imaging evidence that the

    2011-10-01

    Full Text Available The majority of startups fail to consider sales execution as part of their overall strategy. This article demonstrates how a sales execution strategy can help a company take a product or service to market more efficiently and effectively by focusing on the customers that are key to generating revenue. Combined with techniques for recruiting effectively and measuring sales outcomes, a sales execution strategy helps technology startups exceed growth aspirations and potentially reduce or even eliminate the requirement for external investment. In this article, we first describe the focus of assistance currently given to startups and the reasons why sales execution strategies are often overlooked. Next, we outline recommendations for developing, implementing, and supporting a sales execution strategy. Finally, we summarize the key points presented in the article.

  19. Executive control suppresses pupillary responses to aversive stimuli.

    Science.gov (United States)

    Cohen, Noga; Moyal, Natali; Henik, Avishai

    2015-12-01

    Adaptive behavior depends on the ability to effectively regulate emotional responses. Continuous failure in the regulation of emotions can lead to heightened physiological reactions and to various psychopathologies. Recently, several behavioral and neuroimaging studies showed that exertion of executive control modulates emotion. Executive control is a high-order operation involved in goal-directed behavior, especially in the face of distractors or temptations. However, the role of executive control in regulating emotion-related physiological reactions is unknown. Here we show that exercise of executive control modulates reactivity of both the sympathetic and the parasympathetic components of the autonomic nervous system. Specifically, we demonstrate that both pupillary light reflex and pupil dilation for aversive stimuli are attenuated following recruitment of executive control. These findings offer new insights into the very basic mechanisms of emotion processing and regulation, and can lead to novel interventions for people suffering from emotion dysregulation psychopathologies.

    2016-01-01

    Executive functioning (EF) deficits are well recognized in developmental dyslexia, yet the majority of studies have concerned children rather than adults, ignored the subjective experience of the individual with dyslexia (with regard to their own EFs), and have not followed current theoretical perspectives on EFs. The current study addressed these shortfalls by administering a self-report measure of EF (BRIEF-A; Roth, Isquith, & Gioia, 2005) and experimental tasks to IQ-matched groups of adults with and without dyslexia. The laboratory-based tasks tested the three factors constituting the framework of EF proposed by Miyake et al. (2000). In comparison to the group without dyslexia, the participants with dyslexia self-reported more frequent EF problems in day-to-day life, with these difficulties centering on metacognitive processes (working memory, planning, task monitoring, and organization) rather than on the regulation of emotion and behaviour. The participants with dyslexia showed significant deficits in EF (inhibition, set shifting, and working memory). The findings indicated that dyslexia-related problems have an impact on the daily experience of adults with the condition. Further, EF difficulties are present in adulthood across a range of laboratory-based measures, and, given the nature of the experimental tasks presented, extend beyond difficulties related solely to phonological processing.

  3. Verbal Fluency: Language or Executive Function Measure?

    Whiteside, Douglas M; Kealey, Tammy; Semla, Matthew; Luu, Hien; Rice, Linda; Basso, Michael R; Roper, Brad

    2016-01-01

    Measures of phonemic and semantic verbal fluency, such as FAS and Animal Fluency (Benton, Hamsher, & Sivan, 1989), are often thought to be measures of executive functioning (EF). However, some studies (Henry & Crawford, 2004a , 2004b , 2004c ) have noted there is also a language component to these tasks. The current exploratory factor-analytic study examined the underlying cognitive structure of verbal fluency. Participants were administered language and EF measures, including the Controlled Oral Word Association Test (FAS version), Animal Fluency, Boston Naming Test (BNT), Vocabulary (Wechsler Adult Intelligence Scale-III), Wisconsin Card-Sorting Test (WCST, perseverative responses), and Trail-Making Test-Part B (TMT-B). A 2-factor solution was found with the 1st factor, language, having significant loadings for BNT and Vocabulary, while the second factor was labeled EF because of significant loading from the WCST and TMT-B. Surprisingly, FAS and Animal Fluency loaded exclusively on to the language factor and not EF. The current results do not exclude EF as a determinant of verbal fluency, but they do suggest that language processing is the critical component for this task, even without significant aphasic symptoms. Thus, the results indicated that both letter (phonemic) and category (semantic) fluency are related to language, but the relationship to EF is not supported by the results.

  4. Unconscious goal activation and the hijacking of the executive function.

    Science.gov (United States)

    Marien, Hans; Custers, Ruud; Hassin, Ran R; Aarts, Henk

    2012-09-01

    Building on research on unconscious human goal pursuit and the dynamic nature of our mental and physical world, this study examined the idea that an unconsciously activated goal hijacks executive control for its own attainment. This "hijacking" of the executive function by an unconscious goal should be evidenced by impaired performance on an unrelated task relying on executive control. The results of 6 experiments show that subliminal activation of a socializing goal, or an idiosyncratic personal goal, or an academic goal, harmed participants' performance on an executive function task, such as inhibition of prepotent responses and detection of text errors during reading. These effects were unique to executive control, were similar when the goal was activated consciously, and were independent of task motivation and perceived inter-goal relatedness between the primed goal and task goal. Furthermore, an unconscious goal occupied executive control to advance itself more strongly when the goal had personal value. Implications for theory and research on unconscious goal pursuit and the executive function are discussed.

    Poor executive functioning is associated with life-long difficulty. Identification of children at risk for executive dysfunction is important for early intervention to improve neurodevelopmental outcomes. This study is designed to examine relationships between birthweight and executive functioning in US children during kindergarten. Our hypothesis was that children with higher birthweights would have better executive function scores. We evaluated data from 17506 US children from the Early Childhood Longitudinal Study-Kindergarten 2011 cohort. Birthweight and gestational age were obtained by parental survey. Executive functions were directly assessed using the number reverse test and card sort test to measure working memory and cognitive flexibility, respectively. Teacher evaluations were used for additional executive functions. Data were analyzed using SAS to run all linear and logistical regressions. For every kilogram of birthweight, scores of working memory increased by 1.47 (Pexecutive functioning. As birthweight increases executive function scores improve, even among infants born normal weight. Further evaluation of this population including interventions and progression through school is needed.

    To assess long-term impairments of executive functioning in adult survivors of bronchopulmonary dysplasia (BPD). Participants were assessed on measures of executive functioning, health-related quality of life (HRQoL) and social functioning. Survivors of BPD (n = 63; 34 males; mean age 24.2 years) were compared with groups comprising preterm (without BPD) (executive functioning relating to problem solving (OR: 5.1, CI: 1.4-19.3), awareness of behavior (OR: 12.7, CI: 1.5-106.4) and organization of their environment (OR: 13.0, CI: 1.6-107.1). Birth weight, HRQoL and social functioning were predictive of deficits in executive functioning. This study represents the largest sample of survivors into adulthood of BPD and is the first to show that deficits in executive functioning persist. Children with BPD should be assessed to identify cognitive impairments and allow early intervention aimed at ameliorating their effects. Implications for Rehabilitation Adults born preterm with very-low birth weight, and particularly those who develop BPD, are at increased risk of exhibiting defects in executive functioning. Clinicians and educators should be made aware of the impact that BPD can have on the long-term development of executive functions. Children and young adults identified as having BPD should be periodically monitored to identify the need for possible intervention.

    Individuals frequently retrieve an intention, but the execution of the task needs to be delayed due to ongoing task demands - so-called delay-execute prospective memory (PM) tasks. We investigated commission errors in the delay-execute paradigm. Participants were told that a PM task is finished (PM task has been executed and is now finished for a final phase) or cancelled (PM task has been cancelled immediately after introduction). We observed commission errors and ongoing task performance in the final phase which included several irrelevant PM cues. In two experiments, we observed significantly more commission errors for cancelled compared to the finished intentions. In Experiment 2, commission errors were eliminated if the final phase required divided attention, regardless of PM task status. In addition, we observed significantly more PM cue interference on the ongoing task in the cancelled compared to the finished group, indicating that the PM task was retrieved in the cancelled group but not in the finished group. As retrieval and execution of the PM task were separated by a delay, the results indicate that commission errors are not always the result of a quick, spontaneous retrieval-execution sequence and may also occur when retrieval and execution are temporally separated.

  8. Assessing executive functions in preschoolers using Shape School Task

    Full Text Available Over the last two decades, there has been a growing interest in the study of the development of executive functions in preschool children due to their relationship with different cognitive, psychological, social and academic domains. Early detection of individual differences in executive functioning can have major implications for basic and applied research. Consequently, there is a key need for assessment tools adapted to preschool skills: Shape School has been shown to be a suitable task for this purpose. Our study uses Shape School as the main task to analyze development of inhibition, task-switching and working memory in a sample of 304 preschoolers (age range 3.25-6.50 years. Additionally, we include cognitive tasks for the evaluation of verbal variables (vocabulary, word reasoning and short-term memory and performance variables (picture completion and symbol search, so as to analyze their relationship with executive functions. Our results show age-associated improvements in executive functions and the cognitive variables assessed. Furthermore, correlation analyses reveal positive relationships between executive functions and the other cognitive variables. More specifically, using structural equation modeling and including age direct and indirect effects, our results suggest that executive functions explain to a greater extent performance on verbal and performance tasks. These findings provide further information to support research that considers preschool age to be a crucial period for the development of executive functions and their relationship with other cognitive processes

    In the near future, autonomous mobile robots are expected to help humans by performing service tasks in many different areas, including personal assistance, transportation, cleaning, mining, or agriculture. In order to manage these tasks in a changing and partially unpredictable environment without the aid of humans, the robot must have the ability to plan its actions and to execute them robustly and safely. The robot must also have the ability to detect when the execution does not proceed as planned and to correctly identify the causes of the failure. An execution monitoring system allows the robot to detect and classify these failures. Most current approaches to execution monitoring in robotics are based on the idea of predicting the outcomes of the robot's actions by using some sort of predictive model and comparing the predicted outcomes with the observed ones. In contrary, this paper explores the use of model-free approaches to execution monitoring, that is, approaches that do not use predictive models. In this paper, we show that pattern recognition techniques can be applied to realize model-free execution monitoring by classifying observed behavioral patterns into normal or faulty execution. We investigate the use of several such techniques and verify their utility in a number of experiments involving the navigation of a mobile robot in indoor environments.

  10. A Working Memory System With Distributed Executive Control.

    Science.gov (United States)

    Vandierendonck, André

    2016-01-01

    Working memory consists of domain-specific storage facilities and domain-general executive control processes. In some working memory theories, these control processes are accounted for via a homunculus, the central executive. In the present article, the author defends a mechanistic view of executive control by adopting the position that executive control is situated in the context of goal-directed behavior to maintain and protect the goal and to select an action to attain the goal. On the basis of findings in task switching and dual tasking, he proposes an adapted multicomponent working memory model in which the central executive is replaced by three interacting components: an executive memory that maintains the task set, a collection of acquired procedural rules, and an engine that executes the procedural rules that match the ensemble of working memory contents. The strongest among the rules that match the ensemble of working memory contents is applied, resulting in changes of the working memory contents or in motor actions. According to this model, goals are attained when the route to the goals is known or can be searched when the route is unknown (problem solving). Empirical evidence for this proposal and new predictions are discussed. © The Author(s) 2015.

  11. Motor resonance facilitates movement execution: an ERP and kinematic study

    Directory of Open Access Journals (Sweden)

    Mathilde eMénoret

    2013-10-01

    Full Text Available Action observation, simulation and execution share neural mechanisms that allow for a common motor representation. It is known that when these overlapping mechanisms are simultaneously activated by action observation and execution, motor performance is influenced by observation and vice versa. To understand the neural dynamics underlying this influence and to measure how variations in brain activity impact the precise kinematics of motor behaviour, we coupled kinematics and electrophysiological recordings of participants while they performed and observed congruent or non-congruent actions or during action execution alone. We found that movement velocities and the trajectory deviations of the executed actions increased during the observation of congruent actions compared to the observation of non-congruent actions or action execution alone. This facilitation was also discernible in the motor-related potentials of the participants; the motor-related potentials were transiently more negative in the congruent condition around the onset of the executed movement, which occurred 300 ms after the onset of the observed movement. This facilitation seemed to depend not only on spatial congruency but also on the optimal temporal relationship of the observation and execution events.

    The psychometric properties of the Learning, Executive, and Attention Functioning (LEAF) scale were investigated in an outpatient clinical pediatric sample. As a part of clinical testing, the LEAF scale, which broadly measures neuropsychological abilities related to executive functioning and learning, was administered to parents of 118 children and adolescents referred for psychological testing at a pediatric psychology clinic; 85 teachers also completed LEAF scales to assess reliability across different raters and settings. Scores on neuropsychological tests of executive functioning and academic achievement were abstracted from charts. Psychometric analyses of the LEAF scale demonstrated satisfactory internal consistency, parent-teacher inter-rater reliability in the small to large effect size range, and test-retest reliability in the large effect size range, similar to values for other executive functioning checklists. Correlations between corresponding subscales on the LEAF and other behavior checklists were large, while most correlations with neuropsychological tests of executive functioning and achievement were significant but in the small to medium range. Results support the utility of the LEAF as a reliable and valid questionnaire-based assessment of delays and disturbances in executive functioning and learning. Applications and advantages of the LEAF and other questionnaire measures of executive functioning in clinical neuropsychology settings are discussed.

    Methods by which real-time executive programs can be implemented in a higher order language are discussed, using HAL/S and Path Pascal languages as program examples. Techniques are presented by which noncyclic tasks can readily be incorporated into the executive system. Situations are shown where the executive system can fail to meet its task scheduling and yet be able to recover either by rephasing the clock or stacking the information for later processing. The concept of deadline processing is shown to enable more effective mixing of time and information synchronized systems.

  17. Metaphors and models of executive functioning: comment on Giancola (2000).

    Weingartner, H

    2000-11-01

    Clinical researchers have become increasingly interested in considering the role of normal and impaired executive functioning in psychopathology. The concept of executive functions is, however, often used as a metaphor for a wide range of operations that may, on the one hand, be distinct from one another, but also may be integrated in various ways under different information-processing conditions. A clinician's perspective of executive functioning should take full advantage of the rich body of data and theory that has developed in contemporary cognitive neuroscience around functions such as forms of inhibition and controlled (in contrast to automatic) functions, in a variety of cognitive domains such as making decisions and tracking performance.

    2010-01-01

    Study Objectives: We studied the effects of sleep deprivation on executive functions using a task battery which included a modified Sternberg task, a probed recall task, and a phonemic verbal fluency task. These tasks were selected because they allow dissociation of some important executive processes from non-executive components of cognition. Design: Subjects were randomized to a total sleep deprivation condition or a control condition. Performance on the executive functions task battery was assessed at baseline, after 51 h of total sleep deprivation (or no sleep deprivation in the control group), and following 2 nights of recovery sleep, at fixed time of day (11:00). Performance was also measured repeatedly throughout the experiment on a control task battery, for which the effects of total sleep deprivation had been documented in previously published studies. Setting: Six consecutive days and nights in a controlled laboratory environment with continuous behavioral monitoring. Participants: Twenty-three healthy adults (age range 22–38 y; 11 women). Twelve subjects were randomized to the sleep deprivation condition; the others were controls. Results: Performance on the control task battery was considerably degraded during sleep deprivation. Overall performance on the modified Sternberg task also showed impairment during sleep deprivation, as compared to baseline and recovery and compared to controls. However, two dissociated components of executive functioning on this task—working memory scanning efficiency and resistance to proactive interference—were maintained at levels equivalent to baseline. On the probed recall task, resistance to proactive interference was also preserved. Executive aspects of performance on the phonemic verbal fluency task showed improvement during sleep deprivation, as did overall performance on this task. Conclusion: Sleep deprivation affected distinct components of cognitive processing differentially. Dissociated non-executive

    2011-10-01

    We investigated the mental rehearsal of complex action instructions by recording spontaneous eye movements of healthy adults as they looked at objects on a monitor. Participants heard consecutive instructions, each of the form "move [object] to [location]". Instructions were only to be executed after a go signal, by manipulating all objects successively with a mouse. Participants re-inspected previously mentioned objects already while listening to further instructions. This rehearsal behavior broke down after 4 instructions, coincident with participants' instruction span, as determined from subsequent execution accuracy. These results suggest that spontaneous eye movements while listening to instructions predict their successful execution.

    This discursive paper examines recent research on career progression for nurse executives in Australia. In particular, it focuses on the personal, work-related and professional factors which influence progression. The role of gender, location and the provision of mentoring are also considered. It is suggested that family friendly policies (such as the option to job share or to perform an executive role on a part-time basis), the availability of a mentor, and the opportunity to pursue further education/training are vital in assisting nurses to progress in their executive careers.

    2009-12-01

    This study aimed to specify the deficit in intellectual ability in children with attention deficit hyperactivity disorder (ADHD), by studying the mediating role of impairments in central executive function (EF)-related components (working memory, inhibition, sustained attention) and non-EFs (short-term memory and processing speed). Two hundred and thirty children aged 8-11 years from a population-based sample were assigned to either the ADHD group, the clinical comparison group, or the normal comparison group. The results showed that children with ADHD had poorer fluid and crystallized intelligence, relative to both comparison groups. Further, regarding fluid intelligence, these deficits were not fully mediated by, but rather went beyond, poorer functioning on the studied EF-related components and non-EFs. We tentatively interpret these fluid deficits in children with ADHD as representing deficiencies in a general intellectual resource reflecting executive attentional processes. Concerning crystallized ability, in contrast, the deficit signified impairment in the studied cognitive functions, as indicated by the significant full mediation effect.

    2017-04-24

    We analyzed the effects of bilingualism and age on executive function. We examined these variables along a continuum, as opposed to dichotomizing them. We investigated the impact that bilingualism and age have on two measures of executive control (Stroop and Flanker). The mouse-tracking paradigm allowed us to examine the continuous dynamics of the responses as participants completed each trial. First, we found that the Stroop effect was reduced with younger age and higher levels of bilingualism; however, no Bilingualism by Age interaction emerged. Second, after controlling for baseline, the Flanker effect was not influenced by bilingualism or age. These results support the notion that bilingualism is one way of enhancing some aspects of executive function - specifically those related to the Stroop task - across the adult life span. In sum, different levels of bilingualism, and different ages, result in varying degrees of executive function as measured by the Stroop task.

    Full Text Available The ontogeny of executive functions is essential in explaining differential and normative developmental trends. Executive functions must be studied from an early age given their consequential effects on mental flexibility, monitoring information, planning, and cognitive control. We propose a differential study in alternative developmental courses through observing typical babies, Down syndrome babies, and babies with risk-factors at birth (due to low weight or to congenital hypothyroidism. Applymg Systematic Observational Methodology, spontaneous babies' activity was registered. The results indicated that: a Typical babies showed better shifting and action flexibility in order to obtain a goal, thus better results; b Among the higher risk-babies, the lower efficacy in executive functioning was observed in underweight babies. Those with hypothyroidism were more in line with the typical babies; c Underweight babies showed a good level of combining actions but they obtained inferior results; d Down syndrome babies displayed more executive functioning difficulty, lower flexibility, high perseveration and less error detection.

    Using data from a diverse sample of 620 families residing in rural, predominately low-income communities, this study examined longitudinal links between fathers' sensitive parenting in infancy and toddlerhood and children's early executive functioning, as well as the contribution of maternal sensitive parenting. After accounting for the quality of concurrent and prior parental care, children's early cognitive ability, and other child and family factors, fathers' and mothers' sensitive and supportive parenting during play at 24 months predicted children's executive functioning at 3 years of age. In contrast, paternal parenting quality during play at 7 months did not make an independent contribution above that of maternal care, but the links between maternal sensitive and supportive parenting and executive functioning seemed to operate in similar ways during infancy and toddlerhood. These findings add to prior work on early experience and children's executive functioning, suggesting that both fathers and mothers play a distinct and complementary role in the development of these self-regulatory skills.

    2007-02-01

    Alcoholism is associated with cognitive deficits, which have been interpreted in terms of a specific vulnerability of the frontal lobes to the toxic effects of alcohol. While executive functions in alcoholism have been investigated extensively, only little work has been carried out on social cognition. The aim of the present study was to investigate the association between executive functions, theory of mind and humour processing in alcoholism. A comprehensive neuropsychological test battery was administered to 29 alcoholic patients (Alc) and 29 healthy controls (HC). The test battery included measurements of affect, general intellectual abilities, executive functions, humour processing and theory of mind. The two groups were comparable with respect to affective variables, IQ, gender and age. Group comparisons revealed cognitive as well as affective humour processing deficits of alcoholics in comparison with HC. The observed impairments were related to theory of mind and executive functions. The deficits may contribute to interpersonal problems and are thus of relevance to rehabilitation.

  15. A short executive function training program improves preschoolers’ working memory

    2015-11-01

    Full Text Available Cognitive training has been shown to improve executive functions in middle childhood and adulthood. However, fewer studies have targeted the preschool years – a time when executive functions undergo rapid development. The present study tested the effects of a short four session executive function training program in 54 four-year-olds. The training group significantly improved their working memory from pre-training relative to an active control group. Notably, this effect extended to a task sharing few surface features with the trained tasks, and continued to be apparent three months later. In addition, the benefits of training extended to a measure of mathematical reasoning three months later, indicating that training executive functions during the preschool years has the potential to convey benefits that are both long-lasting and wide-ranging.

  1. Coordinating the activities of a planner and an execution agent

    Science.gov (United States)

    Tate, Austin

    1989-01-01

    A research program was defined that will explore the link between planning and execution systems. A simple scenario was defined in which a very capable off-line planning system interacts with the user and a smaller, less capable, on-line real-time system executing plans and reacting to faults. However, the on-line execution system may have a more flexible representation of the plans it is executing. This imbalance in the capabilities of the two agents involved should clarify some of the research objectives and give an experimental framework for the work. The task is to investigate the knowledge representations and communication protocols needed to link a user stating some requirements for a task to be carried out through a planning system to the (remote) execution agent that can carry out the user's wishes. The notion that a single representation can encapsulate the expression of the user's requirements, the capabilities for action, the communication to the execution agent, the successful or faulty response from the execution agent and the means of keeping the user informed, is examined. Methods of creating plan patches to update the plans separately held by each of the parties involved to keep them in step as they each react to changing circumstances in real-time is investigated. This involves the specification of plan patch attachment points that can be understood by the recipient. Transaction based methods are also investigated for coordinating the activities of the planner with those of the execution agent and user. The trial application area for the research is in the command and control of an advanced Earth Observation Space Platform.

We use a modest dual issue core based on an Explicit Data Graph Execution (EDGE) architecture to implement our approach, called EVX. Unlike most DLP accelerators which utilize additional hard...

    The current study presents a comparison of 2 structural equation models describing the relationship between the executive functions of updating and inhibiting. Although it has been argued that working memory capacity is defined by one?s ability to control the focus of attention, the findings of the current study support a view of the executive control of attention that reflects updating and inhibiting as not entirely dependent on the same resources.

    Hoarding disorder (HD) is a chronic and debilitating psychiatric condition. Midlife HD patients have been found to have neurocognitive impairment, particularly in areas of executive functioning, but the extent to which this is due to comorbid psychiatric disorders has not been clear. The purpose of the present investigation was to examine executive functioning in geriatric HD patients without any comorbid Axis I disorders (n = 42) compared with a healthy older adult comparison group (n = 25). We hypothesized that older adults with HD would perform significantly worse on measures of executive functioning (Wisconsin Card Sort Task [Psychological Assessment Resources, Lutz, Florida, USA] ( Psychological Assessment Resources, 2003) and the Wechsler Adult Intelligence Scale-IV digit span and letter-number sequencing tests [Pearson, San Antonio, TX, USA]). Older adults with HD showed significant differences from healthy older controls in multiple aspects of executive functioning. Compared with healthy controls, older adults with HD committed significantly more total, non-perseverative errors and conceptual level responses on the Wisconsin Card Sort Task and had significantly worse performance on the Wechsler Adult Intelligence Scale-IV digit span and letter-number sequencing tests. Hoarding symptom severity was strongly correlated with executive dysfunction in the HD group. Compared with demographically-matched controls, older adults with HD have dysfunction in several domains of executive functioning including mental control, working memory, inhibition, and set shifting. Executive dysfunction is strongly correlated with hoarding severity and is not because of comorbid psychiatric disorders in HD patients. These results have broad clinical implications suggesting that executive functioning should be assessed and taken into consideration when developing intervention strategies for older adults with HD.

    2017-05-01

    Achievement in mathematics is predicted by an individual's domain-specific factual knowledge, procedural skill and conceptual understanding as well as domain-general executive function skills. In this study we investigated the extent to which executive function skills contribute to these three components of mathematical knowledge, whether this mediates the relationship between executive functions and overall mathematics achievement, and if these relationships change with age. Two hundred and ninety-three participants aged between 8 and 25years completed a large battery of mathematics and executive function tests. Domain-specific skills partially mediated the relationship between executive functions and mathematics achievement: Inhibitory control within the numerical domain was associated with factual knowledge and procedural skill, which in turn was associated with mathematical achievement. Working memory contributed to mathematics achievement indirectly through factual knowledge, procedural skill and, to a lesser extent, conceptual understanding. There remained a substantial direct pathway between working memory and mathematics achievement however, which may reflect the role of working memory in identifying and constructing problem representations. These relationships were remarkably stable from 8years through to young adulthood. Our findings help to refine existing multi-component frameworks of mathematics and understand the mechanisms by which executive functions support mathematics achievement.

    Cognitive control improve planning, action selection to get a goal (flexibly) and their modifiability. Executive functions are a functional construct related with solving process and goal maintenance. Among executive functions we will study the resistance of interference, stopping irrelevant information and the inhibition of a dominant but inapropiate scheme as well as the influence of the type of tutoring during action execution. We studied 15 infants with alternative courses of development (typical babies and Down' syndrome babies) at a developmental level equivalent to 15 months old, and 6 months later. Infant' spontaneous activity is videotaped longitudinally for a 15 minutes period, activity units are codified by a mixed system of categories and quantified in order to know the significative differences on tutoring types, their dynamic an effects associated with infant's executive functions. a) Adult's directive tutoring is more frequent with Down's syndrome babies than with typical babies; b) Directive tutoring is less adjusted and produces more interferences; c) There is a differential capacity to interference resistance, less present in the Down's syndrome babies; d) Executive functioning shows developmental and differential trends. If development is individual and socially influenced, the individual differential efficacy of executive functions and the type of tutoring contributes to typical or atypical developmental course. Educational and health consequences are proposed.

  15. Executive control training from middle childhood to adolescence

    2014-05-01

    Full Text Available Executive functions include a number of higher-level cognitive control abilities, such as cognitive flexibility, inhibition, and working memory serving action control and the flexible adaptation to changes in the environment. These control functions are supported by the prefrontal cortex and therefore develop rapidly across childhood and mature well into late adolescence. Given that executive control is a strong predictor for various life outcomes, such as academic attainment, socioeconomic status, and physical health, numerous training interventions have been designed to improve executive functioning across the lifespan, many of them targeting children and adolescents. Despite the increasing popularity of these trainings, their results are neither robust nor consistent, and the transferability of training-induced performance improvements to untrained tasks seems to be limited. In this review, we provide a selective overview of the developmental literature on process-based cognitive interventions by discussing (1 the concept and the development of executive functions and their neural underpinnings, (2 the effects of different types of executive control training in normally developing children and adolescents, (3 individual differences in training-related performance gains as well as (4 the potential of cognitive training interventions for the application in clinical and educational contexts. Based on recent findings, we consider how transfer of process-based executive control trainings may be supported and how interventions may be tailored to the needs of specific age groups or populations.

    Although deficits in executive functions have been linked with both depression and rumination in adulthood, the nature of the relationship between these constructs is not well understood and remains understudied in adolescence. The present study examined the relationship of rumination and depression to deficits in executive functions in early adolescence, a critical developmental period for the emergence of depression and rumination and the development of executive functions. Participants were 486 early adolescents (52.7% female; 47.1% African American, 48.8% Caucasian; 4.2% Biracial/Multiracial/Other; M age = 12.88 years; SD = .62) and their mothers, recruited through local schools. Measures included (a) a semi-structured diagnostic interview of the mother and adolescent, (b) youth self-report forms assessing depressive symptoms and trait rumination, (c) mother-report forms assessing demographic information, and (d) behavioral tests of executive function (sustained, selective and divided attention, attentional set shifting, and working memory). Gender moderated rumination-set shifting associations, such that rumination predicted better set shifting in boys only. The current level of depressive symptoms moderated rumination-sustained attention associations, such that rumination predicted better sustained attention in those with low levels of depressive symptoms and worse sustained attention in those with high levels of depressive symptoms. Rumination did not predict performance on other measures of executive functions. Likewise, depressive symptoms and diagnosis were not associated with executive functions. Implications for future research are discussed.

    2015-01-01

    The existence of processes common to memory systems and executive functioning was evidenced by studies in the domain of cerebral neuroimaging, individual differences (mainly in normal aging) and, to a lesser extent, neuropsychology. Executive functioning depends on a large antero-posterior brain network, some regions of which (the middle dorsolateral and ventrolateral cortex, the dorsal anterior cingulate cortex) are involved in a series of executive processes, but also in encoding and retrieval of information in episodic memory and short-term memory. A consequence of lesions in frontal areas is to impair strategical organization of the information to-be-processed (an executive process) and thus leads to a lower memory capacity in frontal patients. Moreover, executive abilities will influence both memory efficiency and the associated brain networks even in people without brain pathology. These data attest to the importance of the relationships between executive and memory processes for an optimal cognitive functioning. Recent advances in neuroimaging and electrophysiology data acquisition and analysis techniques should allow us to better determine and understand the fashion in which these relationships work. © Société de Biologie, 2016.

  18. Effects of acute laboratory stress on executive functions

    2016-03-01

    Full Text Available Recent research indicates that stress can affect executive functioning. However, previous results are mixed with respect to the direction and size of effects, especially when considering different subcomponents of executive functions. The current study systematically investigates the effects of stress on the five components of executive functions proposed by Smith and Jonides (1999: Attention and inhibition; task management; planning; monitoring; and coding. Healthy participants (N = 40 were either exposed to the computerized version of the Paced Auditory Serial Addition Test as a stressor (N = 20, or to a rest condition (N = 20. Stress reactions were assessed with heart rate and subjective measures. After the experimental manipulation, all participants performed tasks that measure the different executive functions. The manipulation check indicates that stress induction was successful (i.e., the stress group showed a higher heart rate and higher subjective responses than the control group. The main results demonstrate that stressed participants show a poorer performance compared with unstressed participants in all executive subcomponents, with the exception of monitoring. Effect sizes for the tasks that reveal differences between stressed and unstressed participants are high. We conclude that the laboratory stressor used here overall reduced executive functioning.

  19. Executable Behaviour and the π-Calculus (extended abstract

    Directory of Open Access Journals (Sweden)

    Bas Luttik

    2015-08-01

    Full Text Available Reactive Turing machines extend classical Turing machines with a facility to model observable interactive behaviour. We call a behaviour executable if, and only if, it is behaviourally equivalent to the behaviour of a reactive Turing machine. In this paper, we study the relationship between executable behaviour and behaviour that can be specified in the pi-calculus. We establish that all executable behaviour can be specified in the pi-calculus up to divergence-preserving branching bisimilarity. The converse, however, is not true due to (intended limitations of the model of reactive Turing machines. That is, the pi-calculus allows the specification of behaviour that is not executable up to divergence-preserving branching bisimilarity. Motivated by an intuitive understanding of executability, we then consider a restriction on the operational semantics of the pi-calculus that does associate with every pi-term executable behaviour, at least up to the version of branching bisimilarity that does not require the preservation of divergence.

    2017-02-22

    The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a cognitive battery that contains scales of several cognitive abilities, but no scale in the instrument is exclusively dedicated to executive functioning. Although the subtests allow for observation of executive-type errors, each error is of fairly low base rate, and healthy and clinical normative data are lacking on the frequency of these types of errors, making their significance difficult to interpret in isolation. The aim of this project was to create an RBANS executive errors scale (RBANS EE) with items comprised of qualitatively dysexecutive errors committed throughout the test. Participants included Veterans referred for outpatient neuropsychological testing. Items were initially selected based on theoretical literature and were retained based on item-total correlations. The RBANS EE (a percentage calculated by dividing the number of dysexecutive errors by the total number of responses) was moderately related to each of seven established measures of executive functioning and was strongly predictive of dichotomous classification of executive impairment. Thus, the scale had solid concurrent validity, justifying its use as a supplementary scale. The RBANS EE requires no additional administration time and can provide a quantified measure of otherwise unmeasured aspects of executive functioning.

    Full Text Available BACKGROUND. Student role performance for academic success in secondary education is under represented in the occupational therapy literature, despite the persistently high dropout rate in the United States (Stillwell & Sable, 2013. Executive dysfunction is one of many possible contributors to difficulties in the classroom (Dirette & Kolak, 2004 and is a better indicator of school performance than IQ (Diamond, 2012. This research examined executive functioning of both alternative and traditional high school students to determine if there is a relationship between executive function and academic success as measured by cumulative grade point average. METHOD. 132 high school students from three different school settings were given the Behavioral Rating Inventory of Executive Function-Self Report (BRIEF-SR. The Global Executive Composite (GEC and individual subscale scores were compared to GPA. RESULTS. No significant difference in GEC scores was found among settings. Subscale scores for “inhibition” and “task completion” were significantly different in the alternative school setting. A weak negative correlation was seen between the GEC and GPA. However, academically unsuccessful students scored statistically lower on the GEC. CONCLUSION. Global executive dysfunction was not predicted by setting but was seen in academically unsuccessful students.

    The transition to elementary school is accompanied by increasing demands for children to regulate their attention and behavior within the classroom setting. Executive control (EC) may be critical for meeting these demands; however, few studies have rigorously examined the association between EC and observed classroom behavior. This study examined EC in preschool (age 5 years 3 months) as a predictor of classroom learning engagement behaviors in first grade, using a battery of performance-based EC tasks and live classroom observations in a longitudinal sample of 313 children. Multilevel modeling results indicated that stronger EC predicted more focused engagement and fewer task management and competing responses, controlling for socioeconomic status, child sex, and age at observations. Results suggest that early EC may support subsequent classroom engagement behaviors that are critical for successful transition to elementary school and long-term learning trajectories.

    Hoarding is common among youth with obsessive compulsive disorder (OCD), with up to 26% of OCD youth exhibiting hoarding symptoms. Recent evidence from adult hoarding and OCD cohorts suggests that hoarding symptoms are associated with executive functioning deficits similar to those observed in subjects with attention deficit hyperactivity disorder (ADHD). However, while hoarding behavior often onsets during childhood, there is little information about executive function deficits and ADHD in affected children and adolescents. The study sample included 431 youths (ages 6-17 years) diagnosed with OCD who participated in the OCD Collaborative Genetics Study and the OCD Collaborative Genetics Association Study and completed a series of clinician-administered and parent report assessments, including diagnostic interviews and measures of executive functioning (Behavior Rating Inventory of Executive Functioning; BRIEF) and hoarding severity (Hoarding Rating Scale-Interview; HRS-I). 113 youths (26%) had clinically significant levels of hoarding compulsions. Youths with and without hoarding differed significantly on most executive functioning subdomains and composite indices as measured by the parent-rated BRIEF. Groups did not differ in the frequency of full DSM-IV ADHD diagnoses; however, the hoarding group had significantly greater number of inattention and hyperactivity symptoms compared to the non-hoarding group. In multivariate models, we found that overall BRIEF scores were related to hoarding severity, adjusting for age, gender and ADHD symptoms. These findings suggest an association between hoarding and executive functioning deficits in youths with OCD, and assessing executive functioning may be important for investigating the etiology and treatment of children and adolescents with hoarding and OCD.

    Full Text Available The study was conducted to determine the managerial problems confronted by executive chefs working at 4 and 5-star hotels in Turkey. A survey developed by the researchers was employed as a data collection tool. Answers given by participants were analyzed using “T-test” and “ANOVA” analyses in order to determine whether there are significant differences of opinion on the subject (collated in answers to the survey questionnaire amongst executive chefs, based on answers given by them (expressed as average figures dependent upon such variables as their “Age”, “Gender”, “Educational Status” and “Star status of the hotel within which they worked.” The study results showed that the most important problem confronting executive chefs was “finding educated/trained kitchen personnel.” On the specific problem, “responsibility and authority is not clear within the kitchen,” there was a significant difference of opinion by the gender of the executive chefs. Moreover, there was a significant difference of opinion dependent upon the star status of the hotels within which the chefs worked on the problem of whether or not “the working hours of kitchen personnel were too long.” The findings suggest that there are important problems confronted by executive chefs. Moreover, male and female executive chefs have different opinions on the magnitudes of some specific problems. Whereas there are various reports and similar publications discussing problems faced by executive chefs, the present study is the first one in the literature that solely explore the managerial problems experienced at a kitchen context.

    Full Text Available Orientation: The researcher applied role analysis from the systems psychodynamic perspective to executives in state departments to improve their awareness of the unconscious diversity dynamics that affect their roles.Research purpose: The purpose of this research was to describe the application of systems psychodynamic role analysis and to determine its trustworthiness in assisting executives to work effectively with conscious and unconscious diversity dynamics in their organisations.Motivation for the study: Executives generally struggle to understand the deeper meaning of diversity behaviour that manifests inside and around them, leading to conflict. Without understanding the unconscious meaning of the behaviour, organisations founder easily. Awareness of below-the-surface behaviour leads to insight and taking responsibility for diversity-related behaviours.Research design, approach and method: The researcher coached six executives in South African state departments over a period of 10 months. The coaching addressed and analysed the executives’ organisational roles. She analysed the data using discourse analysis.Main findings: Themes relating to the diversity dynamics of gender, race, ethnicity, authority, disability, language, age, de-authorisation of diversity work and the coaching process emerged. The coaching assisted the executives to gain insights into below-the-surface diversity dynamics, to address diversity in a sustained manner and to take up their organisational roles more effectively.Practical/managerial implications: Coached executives will have a more objective and dynamic experience of diversity issues that manifest in organisations, between colleagues and within themselves.Contribution/value-add: Executive coaching from a systems psychodynamic perspective displays trustworthiness in improving participants’ diversity awareness, especially with regard to gender, race, ethnicity and authorisation.

    There is evidence to suggest the existence of an executive dysfunction in people diagnosed with fibromyalgia, although there are certain inconsistencies between studies. Here, we aim to compare executive performance between patients with fibromyalgia and a control group by using subjective and objective cognitive tests, analyzing the influence of patient mood on the results obtained, and studying associations between the two measures. 82 patients diagnosed with fibromyalgia and 42 healthy controls, matched by age and years of education, were assessed using the Behavioral Rating Inventory of Executive Function - Adult Version (BRIEF-A) as a subjective measure of executive functioning. A selection of objective cognitive tests were also used to measure a series of executive functions and to identify symptoms of depression and anxiety. Patients with fibromyalgia perceived greater difficulties than the control group on all of the BRIEF-A scales. However, after adjustments were made for depression and anxiety the only differences that remained were those associated with the working memory scale and the Metacognition and Global Executive Composite index. In the case of the objective cognitive tests, a significantly worse overall performance was evidenced for the fibromyalgia patients. However, this also disappeared when adjustments were made for depression and anxiety. After this adjustment, fibromyalgia patients only performed significantly worse for the interference effect in the Stroop Test. Although there were no significant associations between most of the objective cognitive tests and the BRIEF-A scales, depression and anxiety exhibited strong associations with almost all of the BRIEF-A scales and with several of the objective cognitive tests. Patients with fibromyalgia showed executive dysfunction in subjective and objective measures, although most of this impairment was associated with mood disturbances. Exceptions to this general rule were observed in the

    Research regarding executive functioning (EF) in children rarely focuses on populations in African or Middle-Eastern Arabic-speaking countries. The current study used a cross-sectional design to examine the developmental trajectories of school-age Tunisian children in three domains of executive control (inhibition of prepotent responses, cognitive flexibility, and working memory) as well as their mutual interactions and the effects of gender and parents' education level. Inhibitory processes, cognitive flexibility, and working memory were assessed using the Stroop test, a version of the Hayling test adapted for children, simple and alternating tasks of verbal fluency, and verbal and visuospatial span tasks (forward and backward spans). The study population included 120 7- to 12-year-old Tunisian children (60 girls, 60 boys) who were grouped and matched for age, gender, and parents' education level. The results revealed an overall effect of age on executive performance, whereas gender and parents' education level showed non-significant effects. In addition, executive indices were significantly associated with fluid intelligence level. Partial correlation analyses (controlled for age) found significant links between indices that assessed the same executive process, except for inhibitory processes; the temporal indices for inhibitory processes showed relative independence. The correlations between indices that assessed distinct executive processes were weaker (but significant). Overall, the results suggest that executive components in school-age Tunisian children operate according to relatively homogeneous developmental trajectories, marked by peaks of maturity that differ according to the assessed index. A transcultural approach to EF is discussed in terms of the unity and diversity of its components.

    2017-10-01

    Full Text Available Alcohol consumption in adolescents causes negative effects on familiar, social, academic life, as well as neurocognitive alterations. The binge drinking (BD pattern of alcohol is characterized by the alternation of episodes of heavy drinking in a short interval of time, and periods of abstinence, a practice that can result in important brain alterations; even more than regular alcohol consumption. The prefrontal cortex, which acts as neural support for the executive processes, is particularly affected by alcohol; however, not all studies are in agreement about how BD alcohol consumption affects executive functioning. Some research has found that alcohol consumption in adolescence does not significantly affect executive functioning while others found it does. It is possible that these discrepancies could be due to the history of alcohol consumption, that is, at what age the subjects started drinking. The aim of our study is to assess the performance on executive functioning tasks of 13–19-year-old adolescents according to their pattern of alcohol consumption. We hypothesize that BD adolescents will perform worse than non-BD subjects in tasks that evaluate executive functions, and these differences will increase depending on how long they have been consuming alcohol. Three hundred and twenty-two students (48.14% females; age range 13–22 years; mean aged 16.7 ± 2.59 participated in the study; all of them had begun drinking at the age of 13 years. Participant were divided into three groups, according to their age range (13–15, 16–18, and 19–22 years and divided according to their pattern of alcohol consumption (BD and control groups. Then, the subjects were evaluated with neuropsychological tasks that assess executive functions like working memory, inhibition, cognitive flexibility, or self-control among others.

Three hundred and twenty-two students (48.14% females; age range 13-22 years; mean aged 16.7 ± 2.59) participated in the study; all of them had begun drinking at the age of 13 years. Participant were divided into three groups, according to their age range (13-15, 16-18, and 19-22 years) and divided according to their pattern of alcohol consumption (BD and control groups). Then, the subjects were evaluated with neuropsychological tasks that assess executive functions like working memory, inhibition, cognitive flexibility, or self-control among others. The entire sample showed a normal improvement in their executive performance, but this improvement was more stable and robust in the control group

    This present study investigated the link between speech-in-speech perception capacities and four executive function components: response suppression, inhibitory control, switching and working memory. We constructed a cross-modal semantic priming paradigm using a written target word and a spoken prime word, implemented in one of two concurrent auditory sentences (cocktail party situation). The prime and target were semantically related or unrelated. Participants had to perform a lexical decision task on visual target words and simultaneously listen to only one of two pronounced sentences. The attention of the participant was manipulated: The prime was in the pronounced sentence listened to by the participant or in the ignored one. In addition, we evaluate the executive function abilities of participants (switching cost, inhibitory-control cost and response-suppression cost) and their working memory span. Correlation analyses were performed between the executive and priming measurements. Our results showed a significant interaction effect between attention and semantic priming. We observed a significant priming effect in the attended but not in the ignored condition. Only priming effects obtained in the ignored condition were significantly correlated with some of the executive measurements. However, no correlation between priming effects and working memory capacity was found. Overall, these results confirm, first, the role of attention for semantic priming effect and, second, the implication of executive functions in speech-in-noise understanding capacities.

    Executive functions (EFs) include a number of higher-level cognitive control abilities, such as cognitive flexibility, inhibition, and working memory, which are instrumental in supporting action control and the flexible adaptation changing environments. These control functions are supported by the prefrontal cortex and therefore develop rapidly across childhood and mature well into late adolescence. Given that executive control is a strong predictor for various life outcomes, such as academic achievement, socioeconomic status, and physical health, numerous training interventions have been designed to improve executive functioning across the lifespan, many of them targeting children and adolescents. Despite the increasing popularity of these trainings, their results are neither robust nor consistent, and the transferability of training-induced performance improvements to untrained tasks seems to be limited. In this review, we provide a selective overview of the developmental literature on process-based cognitive interventions by discussing (1) the concept and the development of EFs and their neural underpinnings, (2) the effects of different types of executive control training in normally developing children and adolescents, (3) individual differences in training-related performance gains as well as (4) the potential of cognitive training interventions for the application in clinical and educational contexts. Based on recent findings, we consider how transfer of process-based executive control trainings may be supported and how interventions may be tailored to the needs of specific age groups or populations.

    Limited research exists to explain differential executive functioning impairment in clinical populations, particularly between the Wisconsin Card Sorting Task (WCST) and the Trail Making Test (TMT). The distribution of clinical diagnoses was examined in patients failing none, one, or both tasks, and executive task performance was compared among dementia-related diagnoses. Two hundred and sixty-six participants received evaluations through an Alzheimer's Disease Research Center, which included executive tasks. Dementia-related diagnoses were established through consensus. Chi-square analyses indicated that TMT failure, with or without WCST failure, possessed higher associations with dementia diagnoses. Repeated measures analysis of variance similarly indicated that participants with dementia, especially mild and moderate severity, performed worse on TMT. Executive dysfunction was observed in dementia-related diagnoses, and TMT failure was implicated in dementia in higher proportions than WCST impairment. Trail Making Test appears more sensitive than WCST for assessing executive impairment across diagnoses, especially when time and resources are limited in screening and clinical settings. © The Author(s) 2015.

    Higher order speeded cognitive abilities depend on efficient coordination of activity across the brain, rendering them vulnerable to age reductions in structural and functional brain connectivity. The concept of "disconnected aging" has been invoked, suggesting that degeneration of connections between distant brain regions cause cognitive reductions. However, it has not been shown that changes in cognitive functions over time can be explained by simultaneous changes in brain connectivity. We followed 119 young and middle-aged (23-52 years) and older (63-86 years) adults for 3.3 years with repeated assessments of structural and functional brain connectivity and executive functions. We found unique age-related longitudinal reductions in executive function over and above changes in more basic cognitive processes. Intriguingly, 82.5% of the age-related decline in executive function could be explained by changes in connectivity over time. While both structural and functional connectivity changes were related to longitudinal reductions in executive function, only structural connectivity change could explain the age-specific decline. This suggests that the major part of the age-related reductions in executive function can be attributed to micro- and macrostructural alterations in brain connectivity. Although correlational in nature, we believe the present results constitute evidence for a "disconnected brain" view on cognitive aging. © The Author 2016. Published by Oxford University Press.

    Full Text Available Bullying is characterized by intentional, repetitive, and persistent aggressive behavior that causes damage to the victim. Many studies investigate the social and emotional aspects related to bullying, but few assess the cognitive aspects it involves. Studies with aggressive individuals indicate impairment in executive functioning and decision-making. The objective of this study was to assess hot and cold executive functions in children who experience bullying. A total of 60 children between 10 and 11 years of age were included in the study. They were divided into four groups: aggressors (bullies, victims, bully-victims, and control. Tests for decision-making, inhibitory control, working memory, and cognitive flexibility were used. The bully group made more unfavorable choices on the Iowa Gambling Task (IGT, which may indicate difficulties in the decision-making process. The victim group took longer to complete the Trail Making Test (Part B than aggressors, suggesting lower cognitive flexibility in victims. The hypothesis that aggressors would have lower performance in other executive functions such as inhibitory control, working memory and cognitive flexibility has not been confirmed. This study indicates that bullies have an impairment of hot executive functions whereas victims have a comparatively lower performance in cold executive functions. In addition to social and cultural variables, neurocognitive and emotional factors seem to influence the behavior of children in bullying situations.

    Tactile perception is inhibited during movement execution, a phenomenon known as tactile suppression. Here, we investigated whether the type of movement determines whether or not this form of sensory suppression occurs. Participants performed simple reaching or exploratory movements. Tactile discrimination thresholds were calculated for vibratory stimuli delivered to participants' wrists while executing the movement, and while at rest (a tactile discrimination task, TD). We also measured discrimination performance in a same vs. different task for the explored materials during the execution of the different movements (a surface discrimination task, SD). The TD and SD tasks could either be performed singly or together, both under active movement and passive conditions. Consistent with previous results, tactile thresholds measured at rest were significantly lower than those measured during both active movement and passive touch (that is, tactile suppression was observed). Moreover, SD performance was significantly better under conditions of single-tasking, active movements, as well as exploratory movements, as compared to conditions of dual-tasking, passive movements, and reaching movements, respectively. Therefore, the present results demonstrate that when active hand movements are made with the purpose of gaining information about the surface properties of different materials an enhanced perceptual performance is observed. As such, it would appear that tactile suppression occurs for irrelevant tactual features during both reaching and exploratory movements, but not for those task-relevant features that result from action execution during tactile exploration. Taken together, then, these results support a context-dependent modulation of tactile suppression during movement execution. PMID:24367346

    Despite ample research documenting deficits in executive functioning for adults with chronic pain, the literature on pediatric patients with chronic pain is limited and provides mixed results. The current study sought to further investigate the nature of executive dysfunction in this population and also examine the relationships between pain intensity, duration, and catastrophizing with sustained attention, working memory, and self- and parent-report of executive functioning. Pediatric pain clinic and rehabilitation program. Forty adolescents with chronic pain and their parents participated in this study. Participants completed neuropsychological measures and standardized self-report questionnaires during a 45- to 60-minute testing session. Fifty percent of this sample of adolescents with chronic pain demonstrated significant difficulties on at least one measure, with nine participants indicating difficulties on multiple measures. Pain significantly increased during the testing session. Pain variables of intensity, duration, and catastrophizing are related to sustained attention and working memory. This study adds support to previous findings suggesting subclinical struggles with executive functioning for adolescents with chronic pain. One-half of the sample indicated difficulties in either sustained attention and/or working memory. Future studies that would more thoroughly examine more complex executive functioning skills in this population would be helpful to further guide multidisciplinary treatment of these patients, particularly regarding whether or not school accommodations are warranted.

    Emotion regulation deficits and executive functioning deficits have independently been shown to increase vulnerability toward engaging in aggressive behaviors. The effects of these risk factors, however, have not been evaluated in relation to one another. This study evaluated the degree to which each was associated with aggressive behaviors in a sample of 168 undergraduate students. Executive functioning (cognitive inhibition and mental flexibility) was assessed with a Stroop-like neuropsychological task. Emotion regulation and aggressive behaviors were assessed via self-report inventories. Results showed main effects for both emotion regulation and executive functioning, as well as a significant interaction, indicating that those who scored lowest in both domains reported engaging in aggressive behaviors the most frequently. When different types of aggression were examined, this interaction was only significant for acts of physical aggression, not for acts of verbal aggression. Therefore, for physical aggression, emotion regulation and executive functioning exerted a moderating effect on one another. The implications are that, at least for acts of physical aggression, relatively strong capabilities in either domain may buffer against tendencies to engage in aggressive behaviors. Thus, both emotion regulation skills and executive functioning abilities may be valuable targets for interventions aiming to reduce aggressive behaviors. © The Author(s) 2015.

    Full Text Available Current standardised neuropsychological tests may fail to accurately capture real-world executive deficits. We developed a computer-based Cooking Task assessment of executive functions and trialled the measure with a normative group before use with a head-injured population. Forty six participants completed the computerised Cooking Task and subtests from standardised neuropsychological tasks, including the Tower and Sorting Tests of executive function from the D-KEFS, and the CAMPROMPT measure of prospective memory, in order to examine whether standardised executive function tasks, predicted performance on measurement indices from the Cooking Task. Findings showed that verbal comprehension, rule detection and prospective memory contributed to measures of prospective planning accuracy and strategy implementation of the Cooking Task. Results also showed that functions necessary for cooking efficacy differ as an effect of task demands (difficulty levels. Performance on rule detection, strategy implementation and flexible thinking EF measures contributed to accuracy on the Cooking Task Findings raise questions about the functions captured by present standardised tasks particularly at varying levels of difficulty and during dual-task performance. Our preliminary findings also indicate that Cooking Task measures can effectively distinguish between EF and FSIQ abilities. Results of the present study indicate that the Cooking Task shows promise as an ecologically valid measure of executive function for future use with a head-injured population and indexes selective EF’s captured by standardised tests.

    Background: No study has evaluated the effects of executive function on follow-up sedentary behavior, which was this study's purpose. Methods: A longitudinal design was employed among 18 young adult college students (Mage = 23.7 years; 88.9% female). Accelerometer-determined sedentary behavior and physical activity, along with executive function, were assessed at baseline. Approximately 8 weeks later, re-assessment of accelerometer-determined sedentary behavior and physical activity occurred. Executive function was assessed using the Parametric Go/No-Go (PGNG) computer task. From this, 2 primary executive function outcome parameters were evaluated, including the Simple Rule and Repeating Rule. Results: After adjusting for baseline sedentary behavior, age, gender, body mass index and baseline moderate-to-vigorous physical activity (MVPA), for every 25% increase in the number of correctly identified targets for the Repeating rule at the baseline assessment, participants engaged in 91.8 fewer minutes of sedentary behavior at the follow-up assessment (β = -91.8; 95% CI: -173.5, -10.0; P = 0.03). Results were unchanged when also adjusting for total baseline or follow-up physical activity. Conclusion: Greater executive function is associated with less follow-up sedentary behavior.

    Patients with schizophrenia have been found impaired in important aspects of their basic and social cognition. Our aim in this study is to explore the relationship between executive function (EF) and theory of mind (ToM) deficiencies in patients that suffer the illness. Twenty-two Spanish-speaking inpatients and 22 healthy controls matched in age, sex, education, language dominance, and premorbid IQ were assessed in EF and ToM abilities. The former were assessed using 10 tasks that covered 5 cognitive dimensions and the latter using 3 different tasks. Correlation analyses were used to explore the level of association between executive and mentalizing abilities. A series of discriminant function analyses were carried out to examine the relative contribution of each executive and mentalizing task to discriminate between patients and controls. Patients showed impairments in both, executive and ToM abilities. The correlation analyses showed a virtual absence of association between EF and ToM abilities within the group of patients, and an almost opposite pattern within the healthy group. ToM performance was more accurate than executive performance to discriminate patients from controls. Although EFs and ToM deficits come into view together in schizophrenia, they appear to belong to different and relatively independent cognitive domains. Copyright © 2013 SEP y SEPB.

    The healthcare industry is known for constant and rapid change, highlighting the need for strong executive leadership. Within this industry, multihospital healthcare systems present particular executive leadership challenges due to their size and complexity, yet our understanding of how these executive-level health system leaders are developed has been extremely limited. The objective of this research was to study the establishment, organization, content, process, evaluation, and evolution of executive leadership development (ELD) programs in U.S. healthcare systems. Results of a national survey of health system CEOs, supplemented by interviews with multiple health system key informants, showed that ELD programs existed in around half of responding U.S. health systems and were especially prevalent among smaller systems. On average the programs were fairly new, with most having been established since 2003. ELD programs were reportedly valued by the health systems, as reflected by respondents' perceptions of program payoffs and sustained budgetary commitment. Specifically, ELD programs are believed to help further healthcare systems' strategic goals, initiate succession planning, and provide local development opportunities. In addition, the majority of program elements were reportedly worth the investment in improving executives' leadership skills and capabilities. Given the imperative to improve leadership capabilities in healthcare, ELD programs provide important opportunities to enable health systems to meet the challenges of a changing health services industry.

  7. Among three different executive functions, general executive control ability is a key predictor of decision making under objective risk

    2014-12-01

    Full Text Available Executive functioning is supposed to have an important role in decision making under risk. Several studies reported that more advantageous decision-making behavior was accompanied by better performance in tests of executive functioning and that the decision-making process was accompanied by activations in prefrontal and subcortical brain regions associated with executive functioning. However, to what extent different components of executive functions contribute to decision making is still unclear. We tested direct and indirect effects of three executive functions on decision-making performance in a laboratory gambling task, the Game of Dice Task (GDT. Using Brand’s model of decisions under risk (2006 we tested seven structural equation models with three latent variables that represent executive functions supposed to be involved in decision making. The latent variables were general control (represented by the general ability to exert attentional and behavioral self-control that is in accordance with task goals despite interfering information, concept formation (represented by categorization, rule detection, and set maintenance, and monitoring (represented by supervision of cognition and behavior. The seven models indicated that only the latent dimension general control had a direct effect on decision making under risk. Concept formation and monitoring only contributed in terms of indirect effects, when mediated by general control. Thus, several components of executive functioning seem to be involved in decision making under risk. However, general control functions seem to have a key role. They may be important for implementing the calculative and cognitively controlled processes involved in advantageous decision making under risk.

  12. Mandatory IFRS adoption and executive compensation: Evidence from China

    2014-03-01

    Full Text Available This study investigates how the mandatory adoption of International Financial Reporting Standards (IFRS affects the contractual benefits of using accounting information to determine executive compensation in China. After controlling for firm and corporate governance characteristics, we find strong evidence supporting the positive role of mandatory IFRS adoption on the accounting-based performance sensitivity of executive compensation. Subsample analysis suggests that improvements in accounting-based performance sensitivity after IFRS adoption differ across regions with various levels of institutional quality and across firms that are affected to a different extent by the adoption. Additional analysis supports the argument that the positive effects of IFRS adoption on the use of accounting performance in executive compensation are driven by the reduction in accounting conservatism associated with IFRS adoption.

    2010-12-01

    Okanda, et al. (2010) reported new evidence concerning associations between language ability, bilingualism, and executive functioning early in development. The paper adds to a growing body of literature suggesting that bilingualism is associated with advantages in executive functioning generally, and the Dimensional Change Card Sort task in particular. However, as with all findings that hinge on between-group comparisons, there is a need to exercise caution before drawing firm conclusions about the effects of bilingualism on the development of executive control. Several lines of recent evidence are outlined that challenge key assumptions underlying the standard account of the bilingual advantage. Okanda, et al.'s findings are discussed in light of this evidence.

    Mastering two languages has been associated with enhancement in human executive control, but previous studies of this phenomenon have exclusively relied on comparisons between bilingual and monolingual individuals. In the present study, we tested a single group of Welsh–English bilinguals engaged in a nonverbal conflict resolution task and manipulated language context by intermittently presenting words in Welsh, English, or both languages. Surprisingly, participants showed enhanced executive capacity to resolve interference when exposed to a mixed compared with a single language context, even though they ignored the irrelevant contextual words. This result was supported by greater response accuracy and reduced amplitude of the P300, an electrophysiological correlate of cognitive interference. Our findings introduce a new level of plasticity in bilingual executive control dependent on fast changing language context rather than long-term language experience. PMID:23946411

    Full Text Available A recent approach to pedagogic challenge, contrastive to the hierarchy approach of Bloom, Anderson, Gagne, Van Hiele, Marzano, Webb and many others, identifies pedagogic challenge with executive function: Pedagogy is defined as challenging if it addresses executive function. Executive function, in turn, is defined by the presence of multiple modalities of topic approach and a multi-parameter development of the topic. This paper discusses operational issues in implementing a teaching methodology based on multi-parameter problems. This paper advocates teaching a multi-parameter topic using a step-by-step incremental approach, introducing one parameter at a time. Examples are presented from trigonometry, actuarial mathematics, statistics and (biblical literary analysis. The paper also discusses the use of the incremental approach for problem creation and remediation.

    Full Text Available Abstract Background We observe two trends in bioinformatics: (i analyses are increasing in complexity, often requiring several applications to be run as a workflow; and (ii multiple CPU clusters and Grids are available to more scientists. The traditional solution to the problem of running workflows across multiple CPUs required programming, often in a scripting language such as perl. Programming places such solutions beyond the reach of many bioinformatics consumers. Results We present Wildfire, a graphical user interface for constructing and running workflows. Wildfire borrows user interface features from Jemboss and adds a drag-and-drop interface allowing the user to compose EMBOSS (and other programs into workflows. For execution, Wildfire uses GEL, the underlying workflow execution engine, which can exploit available parallelism on multiple CPU machines including Beowulf-class clusters and Grids. Conclusion Wildfire simplifies the tasks of constructing and executing bioinformatics workflows.

    Innovation is among the most frequently used word in the business world today. While many businessman and executives agree that innovation is needed to sustain their long term business success, many struggle to understand the concept of innovation. This study aims to measure the understanding level of innovation among the Malaysian executives using a survey questionnaire. Questions regarding innovation were posted to the respondents and they were requested to answer either it was True or False. Each respondent was given scores for their correct answers. The score of the right answers were then categorized into low, moderate and high understanding level. Results of the survey revealed that the understanding level of innovation among the Malaysian Executives is still at moderate level thus leading to the failure of many initiatives introduced by the organization or the government.

    Increased operational autonomy and reduced operating costs have become critical design objectives in next-generation NASA and DoD space programs. The objective is to develop a semi-automated system for intelligent spacecraft operations support. The Spacecraft Operations and Anomaly Resolution System (SOARS) is presented as a standardized, model-based architecture for performing High-Level Tasking, Status Monitoring and automated Procedure Execution Control for a variety of spacecraft. The particular focus is on the Procedure Execution Control module. A hierarchical procedure network is proposed as the fundamental means for specifying and representing arbitrary operational procedures. A separate procedure interpreter controls automatic execution of the procedure, taking into account the current status of the spacecraft as maintained in an object-oriented spacecraft model.

    The present study tested the proposition that disengagement of moral self-sanctions enables prison personnel to carry out the death penalty. Three subgroups of personnel in penitentiaries located in three Southern states were assessed in terms of eight mechanisms of moral disengagement. The personnel included the execution teams that carry out the executions; the support teams that provide solace and emotional support to the families of the victims and the condemned inmate; and prison guards who have no involvement in the execution process. The executioners exhibited the highest level of moral, social, and economic justifications, disavowal of personal responsibility, and dehumanization. The support teams that provide the more humane services disavowed moral disengagement, as did the noninvolved guards but to a lesser degree than the support teams.

  20. Litigation to execution in legal labour relationships. Study case

    Full Text Available Enforced execution is the legal way by which the Creditor under an enforceable order protects his rights by resorting to coercive force of the state. When the Debtor does not comply voluntarily, the Creditor may appeal to the Bailiff to commence the enforced execution in all manner prescribed by law. Of course, the start of compulsory execution is limited by the conditions of admissibility imperatively specified in the law, principally the condition to exist an enforceable order owned by the Creditor. Regarding the order to be enforced, it can be represented either by an enforceable or final judgement, with provisional enforcement or any other document that can be enforced. Procedurally, the provisions of Art.712 of the Civil Procedure Code allow the introduction by a Creditor who has a litigation to execution against the execution itself, against the Closures issued by the Bailiff, and against any other act of enforcement. Jurisdiction of the Court in this matter will be of the Executor Court or the Court in whose district the Debtor is situated, on the date of the appeal. The appeal of the Debtor questions the Parties not only over the acts of execution because the appeal is also allowed over the explanations relative to the meaning, scope or application of the enforceable order, but in the conditions limited by the legal nature of this order. Thus, according to the law when enforceable order is not issued by a Court or Arbitration may be invoked before an Executor Court including reasons of fact or law which could not be discussed during an earlier trial, in the first instance or in an appeal. Basically, if enforced execution is under an enforceable order that is not from a Court, these reasons can be invoked when there is no other processual mean for its abolition. There also can be submitted a complaint against the Closure by which was upheld the appeal for an enforced execution, and the act of execution concerning the division of the

  1. Who do you trust? Presidential delegation in executive orders

    Full Text Available How do presidents decide to delegate? Research on unilateral powers has (often informally assumed that executive orders start and end with the president, but as in all principal-agent relationships, executives rely on subordinates to carry out their directives. Political scientists have explored when and why Congress delegates to the president, but such action often necessitates a response from the White House; namely, the president delegates to the bureaucracy the authority delegated to him by Congress. Bureaucrats may in turn have a wide degree of latitude when implementing the president’s orders. I argue that presidents must make strategic decisions in choosing to whom to delegate, much in the same way that Congress makes certain calculations in deciding whether to delegate to the executive branch.

  2. Executive Functioning Predicts Academic But Not Social Adjustment to University.

    Adjusting well academically and socially has been associated with enhanced academic performance and student retention. The purpose of this study was to examine subthreshold levels of ADHD symptoms such as inattention, hyperactivity, and executive functioning as potential predictors of academic and social adjustment in a healthy sample of university students. Participants were 135 undergraduate university students who completed self-report questionnaires. Hierarchical regression analyses revealed that metacognition (an aspect of executive function), gender, and age were significant predictors of academic adjustment beyond hyperactivity, inattention, and depression. Depression was the only significant predictor of social adjustment. The BASC-College form may identify depression symptoms predictive of social adjustment, but symptoms of inattention or hyperactivity are not sufficiently sensitive to predict academic adjustment. Measures of executive function that include metacognition such as the BRIEF-A may be most promising in identifying skills predictive of academic adjustment. © The Author(s) 2015.

    Full Text Available In this paper, I wish to propose the Integer Allocation employing Tabu Search in conjunction with Simulated Annealing Heuristics for optimizing the distribution of trading executions in investors’ accounts. There is no polynomial algorithm discovered for Integer Linear Programming (a problem which is NP-complete. Generally, the practical experience shows that large-scale integer linear programs seem as yet practically unsolvable or extremely time-consuming. The algorithm described herein proposes an alternative approach to the problem. The algorithm consists of three steps: allocate the total executed quantity proportionally on the accounts, based on the allocation instructions (pro-rata basis; construct an initial solution, distributing the executed prices; improve the solution iteratively, employing Tabu Search in conjunction with Simulated Annealing heuristics.

    1991-03-01

    In this paper, we present an execution scheme allowing a direct and a pipeline evaluation of a Prolog Program. The execution scheme enhances Prolog performances in interpreted mode, by means of associative processing tools embodied in Content Addressable Memories and potential parallelism existing between clauses selection, unification, and access to clause arguments. The interpretation algorithm is distributed on several processing units, which are Content Addressable Memories (CAMs). These latter are generic and reconfigurable dealing with much more Artificial Intelligence applications, through improved target languages like Prolog, Lisp, and Object oriented languages. The model has been evaluated with a functional simulator written in Le-lisp. The results show the CAMs feasibility in improving Prolog execution at performances greater than 160 KLIPS, in interpreted mode.

    Successful human social interactions depend upon the transmission of verbal and non-verbal signals from one individual to another. Non-verbal social communication is realized through our ability to read and understand information present in other people's actions. It has been proposed that employing the same motor programs, we use to execute an action when observing the same action underlies this action understanding. The main prediction of this framework is that action perception should be strongly correlated with parameters of action execution. Here, we demonstrate that subjects' sensitivity to observed movement speeds is dependent upon how quickly they themselves executed the observed action. This result is consistent with the motor theory of social cognition and suggests that failures in non-verbal social interactions between individuals may in part result from differences in how those individuals move. © The Author (2015).

    2016-01-01

    The present study examined relationships between three key executive functions (working memory, inhibition, and mental set-shifting) and multiple types of aggression in a general population sample of 9-year-old children. One hundred and forty-eight children completed a battery of executive function tasks and were rated on aggression by their primary teachers. All executive function (EF) composites were related to a composite measure of aggression. Working memory (WM) was most consistently related to the different types of aggression (overt, relational, reactive, and proactive), whereas inhibition and mental set-shifting only were related to relational and reactive aggression, respectively. Specificity in relations (studied as independent contributions) was generally low with the exception of the relation between WM and relational aggression. Taken together, our results highlight the roles of WM and relational aggression in EF-aggression relations in middle childhood.

    Full Text Available Similar to any other governments, Indonesia government has the role of protecting the security of its citizens via the established police unit. However, the executive unit is often unable to provide response in timely manner due to the huge data size. For the reason, an executive information system (EIS is established in order to provide necessary information to leverage the decision making process. This work intends to establish and evaluate the executive information system and its support to facilitate the efforts to fight crimes in Indonesia territory. The EIS prototype is established and is evaluated on the basis of the six information system success factors where the required data are collected by means of questionnaire. The results suggest that the factors of system quality, information quality, easy-of-use, user satisfaction, and individual and organization impacts are very significant.

    Full Text Available Abstract Visual-motor maturity and executive functions are closely related in the child development process. This study aimed to investigate the relation between visual-motor abilities and executive functions in 83 healthy children between 7 and 10 years old. The tools used were the Bender Gestalt Visual-Motor Test - Gradual Scoring System (B-GSS, Wisconsin Card Sorting Test (WCST, Raven's Progressive Matrices (RPM, and Rey-Osterrieth Complex Figure (ROCF. The correlation between the B-GSS and WCST scores was significantly negative (r = -.23, p < .033, while ROCF variables, such as Total Memory and Total Copy, had a moderate, significant correlation with total B-GSS score (r = -.55, p < .001; r = -.44, p < .001, respectively. The results empirically show the relation between executive functions and visual-motor maturity and are discussed in face of developmental neuropsychology.

    Multiple sclerosis (MS) is a major cause of neurological disability among young adults. The cognitive disorders are the second cause of alteration of quality of life after physical handicap and are often responsible for loss of social-occupational adaptability. The prevalence of cognitive disorders is 40 to 65%. The alteration of executive functions predominates whereas instrumental functions are generally preserved. The assessment of these disorders is often underestimated by the usual battery of neuropsychological tests. However, the link between psychometric results and executive difficulties of daily life is uncertain. To evaluate the sensitivity of an ecological test compared to standard psychometric tests in assessment of executive disorders in MS. Twenty subjects with clinically definite MS were matched for age, sex and pre-morbid intellectual level with control subjects. A battery of neuropsychological and ecological tests was applied to all subjects. The performances on these tests formed a global score of executive function (SFE). The "paper and pencil" multiple errands test was used as the ecological test to examine planning and goal-oriented behavior. We also assessed fatigue and depression with the Fatigue Severity Scale and the Beck Depression Inventory. There was no significant differences between MS patients and controls in neuropsychological executive tests, except for verbal fluencies (p=0.01). The performances were significantly decreased in the MS group for the multiple errands test (p=0.01). 75% of MS subjects have a pathological score for this test. There was a significant link between the performances with this test and SFE (p=0.009). Executive disorders are underestimated in MS. However, we suggest that an ecological approach is more reliable than standard neuropsychological tests to estimate the cognitive difficulties in daily life in MS subjects. The results of our study favor further research to ascertain the usefulness of ecological

    An enduring question is unity vs. separability of executive deficits resulting from impaired frontal lobe function. In previous studies, we have asked how executive deficits link to a conventional measure of fluid intelligence, obtained either by standard tests of novel problem-solving, or by averaging performance in a battery of novel tasks. For some classical executive tasks, such as the Wisconsin Card Sorting Test (WCST), Verbal Fluency, and Trail Making Test B (TMTB), frontal deficits are entirely explained by fluid intelligence. However, on a second set of executive tasks, including tests of multitasking and decision making, deficits exceed those predicted by fluid intelligence loss. In this paper we discuss how these results shed light on the diverse clinical phenomenology observed in frontal dysfunction, and present new data on a group of 15 schizophrenic patients and 14 controls. Subjects were assessed with a range of executive tests and with a general cognitive battery used to derive a measure of fluid intelligence. Group performance was compared and fluid intelligence was introduced as a covariate. In line with our previous results, significant patient-control differences in classical executive tests were removed when fluid intelligence was introduced as a covariate. However, for tests of multitasking and decision making, deficits remained. We relate our findings to those of previous factor analytic studies describing a single principal component, which accounts for much of the variance of schizophrenic patients' cognitive performance. We propose that this general factor reflects low fluid intelligence capacity, which accounts for much but not all cognitive impairment in this patient group. Partialling out the general effects of fluid intelligence, we propose, may clarify the role of additional, more specific cognitive impairments in conditions such as schizophrenia.

    Objective Phenylketonuria (PKU) is a hereditary metabolic disorder that often results in neuropsychological impairment, even in individuals treated early and continuously. This study was conducted to examine processing speed, variability in processing speed, and the relationship between processing speed variables and executive abilities in children with early- and continuously-treated PKU. Method Participants were 42 children with PKU and 81 typically-developing children from 7 to 18 years of age. Children completed three computerized reaction time (RT) tasks (simple reaction time, go/no-go, stimulus-response compatibility) and seven tasks assessing executive abilities (working memory, inhibitory control, strategic processing). Results Performance of children with PKU was significantly slower and more variable than that of controls across the three tasks administered. When age was considered, it was shown that processing speed improved with age to a comparable degree for both groups. Variability in processing speed, however, decreased more with age for the PKU than control group, reflecting the fact that variability in younger, but not older, children with PKU was greater than that of controls. With regard to executive abilities, processing speed and variability contributed to performance on most, but not all, executive tasks; and after controlling for processing speed and variability, executive impairments were still identified in working memory and inhibitory control (not strategic processing). Conclusions These findings indicate that information processing is slower and less efficient in children with PKU. In addition, processing speed and variability contribute to some, but not all, of the impairments in executive abilities observed in children with PKU. PMID:22866986

    Optimizations are considered that are required for efficient execution of code segments that consists of loops over distributed data structures. The PARTI (Parallel Automated Runtime Toolkit at ICASE) execution time primitives are designed to carry out these optimizations and can be used to implement a wide range of scientific algorithms on distributed memory machines. These primitives allow the user to control array mappings in a way that gives an appearance of shared memory. Computations can be based on a global index set. Primitives are used to carry out gather and scatter operations on distributed arrays. Communications patterns are derived at runtime, and the appropriate send and receive messages are automatically generated.

    Paul H. Blackman

    2014-02-01

    Full Text Available During the first two centuries of European colonization of what is now the United States, executions for a variety of offenses relatively frequently involved mass executions, that is, the execution for the same criminal incident of four or more persons. By the time of American independence, some of those crimes had largely ceased to exist or to elicit such punishment, like witchcraft and piracy. However, the punishment of slaves and Indians kept the percentage of executed persons involved in mass executions significant, if not large. During the last quarter of the 19th and first six decades of the 20th century, mass legal executions diminished as a percentage and were largely limited to punishing robbery-related homicides, including felony-homicides of conspirators. Throughout that period, the end of mass executions for a particular crime presaged the end of all executions for that offense, and the last mass legal execution occurred in 1960.

    Modern software systems, which often are concurrent and manipulate complex data structures must be extremely reliable. We present a novel framework based on symbolic execution, for automated checking of such systems. We provide a two-fold generalization of traditional symbolic execution based approaches: one, we define a program instrumentation, which enables standard model checkers to perform symbolic execution; two, we give a novel symbolic execution algorithm that handles dynamically allocated structures (e.g., lists and trees), method preconditions (e.g., acyclicity of lists), data (e.g., integers and strings) and concurrency. The program instrumentation enables a model checker to automatically explore program heap configurations (using a systematic treatment of aliasing) and manipulate logical formulae on program data values (using a decision procedure). We illustrate two applications of our framework: checking correctness of multi-threaded programs that take inputs from unbounded domains with complex structure and generation of non-isomorphic test inputs that satisfy a testing criterion. Our implementation for Java uses the Java PathFinder model checker.

    Full Text Available This study examines accounting fraud in relation to the characteristics of company executives. The study portrays the degree to which company as well as personal motives could urge an executive to commit fraud. Subsequently, we attempt to identify the degree to which certain socio-economic factors and the existence of strong internal audit mechanisms act as deterrence agents. Furthermore, we investigate the personal financial gain in relation to annual income as a motivator to commit fraud. Finally, we examine the optimal imprisonment duration as a deterrent and the overall probability to commit fraud. The research method was based in the distribution of a questionnaire and took place in the city of Thessaloniki and the region of West Macedonia and Thessaly. The participants were executives in the banking, financial and insurance sector. Our findings show that it is mostly personal factors that motivate an executive to commit fraud, but the fear of immediate legal sanctions and the existence of strong internal audit mechanisms are effective deterrence agents.

    Anthony Pak-Hin Kong

    2014-01-01

    Full Text Available Neuroimaging studies suggest that the neural network involved in language control may not be specific to bi-/multilingualism but is part of a domain-general executive control system. We report a trilingual case of a Cantonese (L1, English (L2, and Mandarin (L3 speaker, Dr. T, who sustained a brain injury at the age of 77 causing lesions in the left frontal lobe and in the left temporo-parietal areas resulting in fluent aphasia. Dr. T’s executive functions were impaired according to a modified version of the Stroop color-word test and the Wisconsin Card Sorting Test performance was characterized by frequent perseveration errors. Dr. T demonstrated pathological language switching and mixing across her three languages. Code switching in Cantonese was more prominent in discourse production than confrontation naming. Our case suggests that voluntary control of spoken word production in trilingual speakers shares neural substrata in the frontobasal ganglia system with domain-general executive control mechanisms. One prediction is that lesions to such a system would give rise to both pathological switching and impairments of executive functions in trilingual speakers.

    As the quality of crucial entities can directly affect that of software, their identification and protection become an important premise for effective software development, management, maintenance and testing, which thus contribute to improving the software quality and its attack-defending ability. Most analysis and evaluation on important entities like codes-based static structure analysis are on the destruction of the actual software running. In this paper, from the perspective of software execution process, we proposed an approach to mine dynamic noteworthy functions (DNFM)in software execution sequences. First, according to software decompiling and tracking stack changes, the execution traces composed of a series of function addresses were acquired. Then these traces were modeled as execution sequences and then simplified so as to get simplified sequences (SFS), followed by the extraction of patterns through pattern extraction (PE) algorithm from SFS. After that, evaluating indicators inner-importance and inter-importance were designed to measure the noteworthiness of functions in DNFM algorithm. Finally, these functions were sorted by their noteworthiness. Comparison and contrast were conducted on the experiment results from two traditional complex network-based node mining methods, namely PageRank and DegreeRank. The results show that the DNFM method can mine noteworthy functions in software effectively and precisely.

    A total of 72 participants estimated products of complex multiplications of two-digit operands (e.g., 63 x 78), using two strategies that differed in complexity. The simple strategy involved rounding both operands down to the closest decades (e.g., 60 x 70), whereas the complex strategy required rounding both operands up to the closest decades (e.g., 70 x 80). Participants accomplished this estimation task in two conditions: a no-load condition and a working-memory load condition in which executive components of working memory were taxed. The choice/no-choice method was used to obtain unbiased strategy execution and strategy selection data. Results showed that loading working-memory resources led participants to poorer strategy execution. Additionally, participants selected the simple strategy more often under working-memory load. We discuss the implications of the results to further our understanding of variations in strategy selection and execution, as well as our understanding of the impact of working-memory load on arithmetic performance and other cognitive domains.

  1. Collaborating with executable content across space and time

    Directory of Open Access Journals (Sweden)

    Mahadev Satyanarayanan

    2014-05-01

    Full Text Available Executable content is of growing importance in many domains. How does one share and archive such content at Internet-scale for spatial and temporal collaboration? Spatial collaboration refers to the classic concept of user collaboration: two or more users who are at different Internet locations performing a task using shared context. Temporal collaboration refers to the archiving of context by one user and use of that context by another user, possibly many years or decades later. The term “shared context” has typically meant shared documents or a shared workspace such as a whiteboard. However, executable content forces us to think differently. Just specifying a standardized data format is not sufficient; one has to accurately reproduce computation. We observe that the precise encapsulation of computing state provided by a virtual machine (VM may help us solve this problem. We can cope with large VM size through a streaming mechanism that demand fetches memory and disk state during execution. Based on our positive initial experience with VMs for archiving execution state, we propose the creation of Olive, an Internet ecosystem of curated VM image collections.

    2013-01-01

    Many students have difficulty adjusting to college, and the contribution of academic and relational factors have been considered in previous research. In particular, depression commonly emerges among college women at this time and could be related to poor adjustment to college. This study examined the relationship between executive functions, depressive symptoms, and college adjustment in college women. Seventy-seven female participants from a midsize urban university completed the Wechsler Abbreviated Scale of Intelligence, College Adjustment Scale, Beck Depression Inventory-Second Edition, Behavior Rating Inventory of Executive Function-Adult Version, and four subtests from the Delis-Kaplan Executive Function System: the Trail-Making Test, Design Fluency Test, Verbal Fluency Test, and Color-Word Interference Test. After controlling for IQ score, hierarchical regression analyses showed that subjective and objective measures of executive functioning and depressive symptoms were significantly related to college adjustment problems in academic, relational, and psychological areas. The current study provides evidence for a relationship between cognitive abilities, psychiatric symptoms, and college adjustment.

  14. The Regime of Contracts under Execution within the Insolvency Procedure

    Directory of Open Access Journals (Sweden)

    Cornelia Lefter

    2008-01-01

    Full Text Available According to the Romanian law the debtor that faces financial difficulties of a certain extent can be the object of the insolvency procedure, regulated by Law no. 85/2006 concerning the insolvency procedure. Because the insolvent debtor is no longer trustworthy to its contractual partners and cannot execute the assumed obligations, there is a risk that these contracts cease, or the services that are incumbent on contractual parties are not executed. This is why, it is very important to know within the insolvency procedure and, especially during the judicial reorganization period, what will be the treatment of contracts concluded prior to the opening of this procedure and still not executed, the so-called “contracts under execution”. Also, after clarifying the concept of contract under execution, it is important to establish who has the right to opt between their continuation, or their cancellation. On the other hand, there are presented the special rules provided by Law no. 85/2006 for some categories of contracts concluded prior to the opening of the insolvency procedure, such as: labor, lease, commission contracts, master of netting agreement or contracts concluded intuitu personae or by a debtor that is the owner of a leased building, etc.

    Directory of Open Access Journals (Sweden)

    Ezequiel Gleichgerrcht

    2009-01-01

    Full Text Available The aim of this investigation was to evaluate improvement of executive functions after shunt surgery in patients with early normal pressure hydrocephalus (NPH. Patients with NPH were assessed before and after shunt surgery with tests shown to be sensitive to damage to the prefrontal cortex (PFC. Significant differences were found between basal and follow-up performances on the Boston Naming Test, the backwards digits span, Part B of the Trail Making Test, and the number of words produced on the phonological fluency task. In conclusion, our study reveals that patients with NPH who respond positively to continuous slow lumbar cerebral spinal fluid drainage and receive a ventriculoperitoneal shunt implant, improve their performance on tasks of executive function. Due to the high demand for this form of mental processing in real-life complex scenarios, and based on the severe executive deficits present in both demented and non-demented NPH patients, we encourage the assessment of executive functions in this clinical group.

    2016-01-01

    Full Text Available With regard to conceptual similarity between executive functions and intelligence, the aim of this research was to determine their correlation in typically developing children. The sample included 114 children of both sexes (59/51.8% of girls, between 8.7 and 10.8 years of age (M=9.80; SD=0.57. Dodrill's Stroop Test, Go/No-Go Task, Listening Span Task, Digit Span Backward, Odd-one-out span, Figure Span Backward, Wisconsin Card Sorting Test, Twenty Questions Task and Tower of London were used for the assessment of executive functions. Intelligence was assessed by Raven's Progressive Matrices. Pearson's correlation and partial correlation coefficients were used in statistical analysis of the results. A low to moderate correlation was determined between intelligence and the variables of all applied executive functions tasks, both in verbal and non-verbal domain (p≤0.000-0.05. Inhibitory control, cognitive flexibility, and planning ability correlated with fluid intelligence in the range of r=0.20-0.30, while the correlation with working memory was in the range of r=0.40-0.50. The obtained results confirmed the assumption that intelligence and executive functions were different constructs regardless of their conceptual similarity.

  11. The post-capitalist executive. Interview by T George Harris.

    Science.gov (United States)

    Drucker, P F

    1993-01-01

    For half a century, Peter F. Drucker has influenced senior executives across the globe with his rare insight into socioeconomic forces and practical advice for navigating often turbulent managerial waters. In his latest contribution to HBR, Drucker discusses the impact of the ideas in his latest work, Post-Capitalist Society, on the day-to-day lives and careers of managers. Drucker argues that managers must learn to negotiate a new environment with a different set of work rules and career expectations. Companies currently face downsizing and turmoil with increasing regularity. Once built to last like pyramids, corporations are now more like tents. In addition, businesses in the post-capitalist society grow through many and varied complicated alliances often baffling to the traditional manager. Confronted by these changes, managers must relearn how to manage. In the new world of business, information is replacing authority as the primary tool of the executive. And, Drucker advises, one embarks on the road toward information literacy not by buying the latest technological gadget but by identifying gaps in knowledge. As companies increasingly become temporary institutions, the manager also must begin to take individual responsibility for himself or herself. To that end, the executive must explore what Drucker calls competencies: a person's abilities, likes, dislikes, and goals, both professional and personal. If executives rise to these challenges, a new organizational foundation will be built. While a combination of rank and power supported the traditional organization, the internal structure of the emerging organization will be mutual understanding and trust.

    Science.gov (United States)

    Rossiter, A M; Greene, B R; Kralewski, J E

    2000-10-01

    This article is the first of two studies conducted by the American College of Medical Practice Executives (ACMPE) that examines the perceived roles of medical practice executives. (Founded in 1956, the American College of Medical Practice Executives is the professional development and credentialing arm of the Medical Group Management Association (MGMA)). This study asked groups of physicians and nonphysician administrators to identify the competencies and associated skills and knowledge for administering group practices in today's changing environment. Those surveyed included administrators who are Fellows in ACMPE and 795 physicians who comprise the Society of Physician Administrators of the Medical Group Management Association. The responses were examined through a framework provided by the Managed Care Process Model. In this model, the focus is on the administrative and clinical processes required by different levels of managed care market penetration. The model progresses from a focus on relatively traditional practice management functions to those activities that are more complex with a greater focus on the integration of both clinical and business processes aimed at the health of populations. The analysis of the perceived competencies indicated that while both executive types perceived the importance of managing the health of populations, that task is not yet being incorporated into their professional roles.

  17. Management development: a needs analysis for nurse executives and managers.

    Science.gov (United States)

    Kirk, R

    1987-04-01

    Clearly, both the nurse executive and nurse manager roles are becoming more complex. I feel an enthusiasm by the professionals in those positions to pursue development activities that will help them do their jobs better and with less discomfort. Nurse executives obviously know the power of combining knowledge with experience. How do the different leadership and management development needs identified by these NE fit with your organization's needs? What is the content in your leadership and management development programs? Are your programs meeting the real needs of your executive and management-level staff? One way to find out is to do a simple survey. Today, nurse executives are responsible and accountable for challenges we never considered possible, even a few years ago. But along with the new challenges came the flexibility and positive attitudes of NEs to respond to changes and acquire new skills such as cost accounting, computers, or marketing. It's this type of proactive thinking that helps nurse leaders turn problems into opportunities and their situations into success stories.

  8. Is preschool executive function causally related to academic achievement?

    Science.gov (United States)

    Willoughby, Michael T; Kupersmidt, Janis B; Voegler-Lee, Mary E

    2012-01-01

    The primary objective of this study was to reevaluate the well-established result that preschoolers' performance on executive function tasks are positively associated with their performance on academic achievement tests. The current study replicated the previously established concurrent associations between children's performance on EF tasks and academic achievement tests. Specifically, children's performance on measures of inhibitory and motor control were positively associated with their performance on tests of reading, writing, and mathematics achievement (rs = .2-.5); moreover, although diminished in magnitude, most of these associations held up even after including an earlier measure of academic achievement as a covariate (rs = .1-.3). However, the application of an alternative analytic method, fixed effects analysis, a method that capitalizes on repeated measures data to control for all time stable measured and unmeasured covariates, rendered the apparent positive associations between executive function and academic achievement nonsignificant (rs = .0-.1). Taken together, these results suggest that the well-replicated association between executive function abilities and academic achievement may be spurious. Results are discussed with respect to the importance of utilizing analytic methods and research designs that facilitate strong causal inferences between executive function and academic achievement in early childhood, as well as the limitations of making curriculum development recommendations and/or public policy decisions based on studies that have failed to do so.

    2017-08-01

    Cognitive deficits following stroke are well documented, but less is known about problems with social skills such as understanding others' thoughts and feelings. This study investigated the effect of stroke on a visual-affective measure of social understanding: the Reading the Mind in the Eyes test (RMET). The aims were to investigate whether right hemisphere stroke was particularly detrimental to this aspect of Theory of Mind (ToM), and investigate the relationship between ToM ability and executive function following stroke. Performance of stroke patients (right hemisphere stroke, n = 15; left hemisphere stroke, n = 15) was compared to that of controls (n = 40) matched for age, years of education, and IQ on tasks measuring ToM and executive functioning. Right hemisphere stroke was associated with impaired ToM ability, but left hemisphere stroke was not. There was no effect of stroke on a matched non-ToM control task. High correlations were found between performance on the RMET and some measures of executive functioning in participants with right hemisphere stroke only. Further analyses suggested that deficits in executive functioning could not statistically explain all of the difficulties shown by stroke participants on the RMET. A reduction in the ability to attribute mental states to others following right hemisphere stroke may adversely affect psychosocial functioning, disrupt interpersonal relationships, and lead to reduced quality of life. The clinical importance of these findings, implications for clinical practice and future research are discussed.

    Towe-Goodman, Nissa R.; Willoughby, Michael; Blair, Clancy; Gustafsson, Hanna C.; Mills-Koonce, W. Roger; Cox, Martha J.

    2014-01-01

    Using data from a diverse sample of 620 families residing in rural, predominately low-income communities, this study examined longitudinal links between fathers’ sensitive parenting in infancy and toddlerhood and children’s early executive functioning, as well as the contribution of maternal sensitive parenting. After accounting for the quality of concurrent and prior parental care, children’s early cognitive ability, and other child and family factors, fathers’ and mothers’ sensitive and supportive parenting during play at 24-months predicted children’s executive functioning at 3-years of age. In contrast, paternal parenting quality during play at 7-months did not make an independent contribution above that of maternal care, but the links between maternal sensitive and supportive parenting and executive functioning seemed to operate in similar ways during infancy and toddlerhood. These findings add to prior work on early experience and children’s executive functioning, suggesting that both fathers and mothers play a distinct and complementary role in the development of these self-regulatory skills.

  4. Postponement of execution of the administrative act in administrative dispute

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available The newly established legal regime postponement of execution administrative acts in an administrative dispute, contains a number of elements that significantly contribute to raising quality of the legal position of parties in administrative matters. One of the most important innovation is the establishment of an administrative court jurisdiction to decide on the request of the Prosecutor for a stay of execution of an administrative act challenged in administrative proceedings, particularly against administrative acts which appealed the appellate administrative body that has no suspensive effect. Regardless of some defects that can be seen in the legal regime of postponement of the execution of administrative decisions in administrative proceedings, which are related mainly to the lack of a legal remedy against a court decision on the request for stay of execution of administrative acts and the inability to use temporary measures in the administrative proceedings, with a lot of basis, however, it could be concluded that the new Law on Administrative Disputes created more than a solid legal basis for further promotion of legal security of the parties in administrative matters.
