    The possibility to plan and deliver beam intensity modulated radiotherapy using a general purpose 3D-planning system (Sherouse`s GRATISTM) and a linear accelerator equipped with a standard multileaf collimator (MLC) was investigated in view of limiting the dose at the spinal cord below tolerance. During the planning process, dose homogenization at the target is obtained by the calculation of the weights, given to beam segments of a specific predetermined geometry. This specific geometry maximizes the area of each segment and thus reduces the number of segments. With a virtual patient in supine position, a first planning using a single isocenter, with gantry positions of -60, -30, 0, 30 and 60 degrees was performed. Medial edges of all segments were located tangential to the spinal cord. The resulting dose distribution allowed to encompass the target by an isodose surface of 66-70 Gy without exceeding spinal cord tolerance but required 42 segments distributed over 5 gantry angles. Therefore, dose-volume histogram analysis were performed for those cases where: (1) for some gantry positions, all beam segments could be omitted; (2) at the remaining gantry angles, segments could be omitted; (3) at least 2 segments could be traded off against 1 additional gantry angle. This procedure resulted in a final plan containing 22 segments spread over 8 gantry angles. Preliminary dosimetric results on a RANDO phantom support the robustness of the method. The first clinical applications have been planned. Although up to 99 beam segments can be programmed on the Philips SL25 linear accelerator, it remained impossible to use these segments synchronized with the MLC. From a clinical viewpoint, the proposed treatment for irradiating lower neck and upper mediastinal targets could be used as a standard against which other solutions might be tested.

    The hurried development of multimedia and internet allows for wide distribution of digital media data. It becomes much easier to edit, modify and duplicate digital information. In additional, digital document is also easy to copy and distribute, therefore it may face many threats. It became necessary to find an appropriate protection due to the significance, accuracy and sensitivity of the information. Furthermore, there is no formal method to be followed to discover a hidden data. In this paper, a new information hiding framework is presented.The proposed framework aim is implementation of framework computation between advance encryption standard (AES) and distortion technique (DT) which embeds information in image page within executable file (EXE file) to find a secure solution to cover file without change the size of cover file. The framework includes two main functions; first is the hiding of the information in the image page of EXE file, through the execution of four process (specify the cover file, spec...

    A Previously traditional methods were sufficient to protect the information, since it is simplicity in the past does not need complicated methods but with the progress of information technology, it become easy to attack systems, and detection of encryption methods became necessary to find ways parallel with the differing methods used by hackers, so the embedding methods could be under surveillance from system managers in an organization that requires the high level of security. This fact requires researches on new hiding methods and cover objects which hidden information is embedded in. It is the result from the researches to embed information in executable files, but when will use the executable file for cover they have many challenges must be taken into consideration which is any changes made to the file will be firstly detected by untie viruses, secondly the functionality of the file is not still functioning. In this paper, a new information hiding system is presented. The aim of the proposed system is to ...

    "We have a new strategy to grow our organization." Developing the plan is just the start. Implementing it in the organization is the real challenge. Many organizations don't fail due to lack of strategy; they struggle because it isn't effectively implemented. After working with hundreds of companies on strategy development, Denise and Robert have distilled the critical areas where organizations need to focus in order to enhance profitability through superior execution. If these questions are important to your organization, you'll find useful answers in the following articles: Do you find yourself overwhelmed by too many competing priorities? How do you limit how many strategic initiatives/projects your organization is working on at one time? How do you balance your resource requirements (time and money) with the availability of these resources? How do you balance your strategic initiative requirements with the day-to-day requirements of your organization?

    The current trend toward chip multiprocessor architectures has placed great pressure on programmers and compilers to generate thread-parallel programs. Improved execution performance can no longer be obtained via traditional single-thread instruction level parallelism (ILP), but, instead, via multithreaded execution. One notable technique that facilitates the extraction of parallel threads from sequential applications is thread-level speculation (TLS). This technique allows pro...

    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

    In order to analyze the debonding failure of the shear-flexure zone of FRP (fiber reinforced plastics) strengthened reinforced concrete beams, a simple three dimensional nonlinear finite element model, based on a "beam segment" between two cracks of a strengthened beam, was built. An application of Saint-Venant principle and a numerical study were carried out to prove the rationality and reliability of the proposed model. Based on this model, the debonding load of FRP strengthened beams,under the influence of differenct stress levels of FRP, layers of FRP, shear-span ratio, FRP-concrete constitutive laws and length of beam segment, were analyzed by nonlinear finite element method. The numerical analysis indicate that the debonding failure is induced mainly by FRP stress and the number of FRP layers. There is a substantial agreement between our numerical calculation and existing experimental results.%为更合理分析增强纤维复合材料(FRP)加固混凝土梁剪弯段的剥离破坏,提出了一个基于加固梁两裂缝间梁段的空间有限元模型,并用圣维南原理和数值方法证实其合理性和可靠性;进而以FRP应力、FRP层数、剪跨比、FRP-混凝土粘结滑移本构关系和梁段长度作为影响因素,对此模型做非线性有限元计算分析.结果表明:FRP应力和层数对剥离荷载有显著影响,数值计算与多个既有实验结果基本一致.

    基于程序谱的错误定位技术由于其较高的定位效率已成为当前软件调试领域研究热点之一.这种技术通常根据测试覆盖信息计算程序语句发生错误的可疑度来进行错误定位.然而,这种技术会随着程序中错误数目的增多效率不断下降.鉴于此,提出了一种基于条件执行切片谱的多错误定位技术(conditioned execution slicing spectrum-based multiple fault localization,CESS-MFL),以提高多错误定位的效率.CESS-MFL技术首先根据输入变量的谓词条件构建错误相关条件执行切片的谱矩阵,然后依次计算错误相关条件执行切片中的元素(语句或语句块)的可疑度,并生成可疑度报告.实验验证了CESS-MFL技术比当前流行的基于程序谱的Tarantula技术、基于程序切片的Intersection技术、Union技术有更高的多错误定位效率,并且可在有效的时间和空间复杂度内完成.

    International Nuclear Information System (INIS)

    The State-of-the-Art Report on Multi-scale Modelling of Nuclear Fuels describes the state of fundamental materials models that can represent fuel behaviour, the methodologies for obtaining material properties, and modelling principles as they can be implemented in fuel performance codes. This report, while far from being a detailed assessment of nuclear fuel modelling, provides a recognition of the approaches to the significant aspects of fuel modelling and examples of their application. Fuel behaviour phenomena are discussed that are applicable across the spectrum of fuel forms, from conventional LWR oxide pellets to MOX, carbide, and metal SFR fuel, to coated particle fuel for gas-cooled reactors. A key issue is microstructural evolution during burn-up, and the state of understanding of that phenomenon is considered at length. Covered in the discussions are the basic material properties of heat capacity, free energy, and thermal conductivity and diffusion. Also included are the more functional effects of restructuring, bubble formation, constituent redistribution, fuel and clad oxidation, and fuel clad and environmental interactions. Fuel fabrication is considered as are many material modelling challenges, such as representing injection casting of metallic fuels, as seen in the preparation of nuclear fuel. The last set of contributions covered the basic principles for modelling phenomena and determining fundamental materials properties, a look at the state of fuel performance codes and a last note about integrating across multiple scales. The state-of-the-art of modelling phenomena related to nuclear fuel has advanced significantly in recent years. The representation of atomic level behaviour is increasingly becoming more accurate as capabilities to utilise larger sets of atoms evolve and empirical potentials improve. At the mesoscale, models for transport and microstructure evolution have also progressed with new techniques that well represent restructuring. At

    Zapateado is a repetitive percussive footwork in dance. This percussive movement, and the differences in technique, may be risk factors for injury. A survey on zapateado dance students found a rate of 1.5 injuries/1,000 exposures. Knee injuries are more frequent than in Spanish dancers than folkloric dancers. The aim of this research was to study the relationship between technique and ground reaction force between zapateado on Spanish and Mexican folkloric dancers. Ten female dance students (age 22.4 ± 4 yrs), six Spanish dancers and four Mexican folkloric dancers, were considered. Each student performed zapateado with a flat foot, wearing high-heeled shoes during 5 seconds on a force platform. Videotapes were taken on a lateral plane, and knee and hip angles in each movement phase were measured with Dartfish software. Additionally, knee and ankle flexor and extensor strength was measured with a dynamometer. Ground reaction forces were lower for Spanish dancers than Mexican folkloric dancers. Spanish dancers had less knee flexion when the foot contacted to the ground than did Mexican folkloric dancers. On Spanish dancers, the working leg had more motion in relation to hip and knee angles than was seen in folkloric dancers. The ankle extensors were stronger on folkloric dancers, and there were no differences for the other muscle groups. Knee flexion at foot contact and muscle strength imbalance could be risk factors for injuries. It is suggested that the technique in Spanish dance in Mexico be reviewed, although more studies are required to define more risk factors. PMID:23752281

    Similar execution paths generation is one of the fundamental tasks in code analysis and detection .The current methods usually target to the program behavior or program structure ,and change the value of key predicates ,but these methods has a low effectiveness due to the lack of the necessary guidance information ,Meanwhile ,the predicates set has a large size and usually hard to solve ,thus it will reduce the analyze precision as well .A technique of similar execution paths generation based on dynamic synergy bidirectional mapping is proposed in this paper .According to extend the shape of Control Flow Graph and use the backward symbolic analysis ,the weakest precondition of the candidate path is generated ,which can be used as the guidance information to generate pointed similar execution paths set according to the edit distance via changing the distance factor .The experimental results show that this method has the advantage of precision and anti-inference .%相似执行路径的生成是代码分析和检测的基础性工作之一,现有的方法通常以程序的行为序列或结构为分析对象,通过改变关键谓词的取值等方法来进行分析,但由于缺乏必要的引导信息导致生成的相似路径的有效性较低,另外由于路径的谓词集合较长而难以求解也降低了分析的精度。提出基于动态协同双向映射的分析方法,通过对程序控制流图的表示形式进行扩展,结合后向符号分析的方法生成候选路径的最弱前置条件,并以此为引导信息使用编辑距离的方法通过改变距离因子的取值来生成有针对性的相似路径集合。实验结果表明,与现有的方法相比,该方法的准确性和效率有明显的优势。

  16. Tabled Execution in Scheme

    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.

    Reasoning, problem solving, comprehension, learning and retrieval, inhibition, switching, updating, or multitasking are often referred to as higher cognition, thought to require control processes or the use of a central executive. However, the concept of an executive controller begs the question of what is controlling the controller and so on, leading to an infinite hierarchy of executives or "homunculi". In what is now a QJEP citation classic, Baddeley [Baddeley, A. D. (1996). Exploring the central executive. Quarterly Journal of Experimental Psychology, 49A, 5-28] referred to the concept of a central executive in cognition as a "conceptual ragbag" that acted as a placeholder umbrella term for aspects of cognition that are complex, were poorly understood at the time, and most likely involve several different cognitive functions working in concert. He suggested that with systematic empirical research, advances in understanding might progress sufficiently to allow the executive concept to be "sacked". This article offers an overview of the 1996 article and of some subsequent systematic research and argues that after two decades of research, there is sufficient advance in understanding to suggest that executive control might arise from the interaction among multiple different functions in cognition that use different, but overlapping, brain networks. The article concludes that the central executive concept might now be offered a dignified retirement.

    Over the last decade, executable models of biological behaviors have repeatedly provided new scientific discoveries, uncovered novel insights, and directed new experimental avenues. These models are computer programs whose execution mechanistically simulates aspects of the cell's behaviors. If the observed behavior of the program agrees with the observed biological behavior, then the program explains the phenomena. This approach has proven beneficial for gaining new biological insights and directing new experimental avenues. One advantage of this approach is that techniques for analysis of computer programs can be applied to the analysis of executable models. For example, one can confirm that a model agrees with experiments for all possible executions of the model (corresponding to all environmental conditions), even if there are a huge number of executions. Various formal methods have been adapted for this context, for example, model checking or symbolic analysis of state spaces. To avoid manual construction of executable models, one can apply synthesis, a method to produce programs automatically from high-level specifications. In the context of biological modeling, synthesis would correspond to extracting executable models from experimental data. We survey recent results about the usage of the techniques underlying synthesis of computer programs for the inference of biological models from experimental data. We describe synthesis of biological models from curated mutation experiment data, inferring network connectivity models from phosphoproteomic data, and synthesis of Boolean networks from gene expression data. While much work has been done on automated analysis of similar datasets using machine learning and artificial intelligence, using synthesis techniques provides new opportunities such as efficient computation of disambiguating experiments, as well as the ability to produce different kinds of models automatically from biological data.

    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.

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

    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.

  12. 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.

  14. 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.

    of electrodes. The main objective of this thesis is to develop top-down synthesis techniques for digital microfluidic biochips. So far, researchers have assumed that operations are executing on virtual modules of rectangular shape, formed by grouping adjacent electrodes, and which have a fixed placement...... on the microfluidic array. However, operations can actually execute by routing the droplets on any sequence of electrodes on the biochip. Thus, we have proposed a routing-based model of operation execution, and we have developed several associated synthesis approaches, which progressively relax the assumption...... that operations execute inside fixed rectangular modules. The proposed synthesis approaches consider that i) modules can dynamically move during their execution and ii) can have non-rectangular shapes. iii) We have relaxed the assumption that all electrodes are occupied during the operation execution, by taking...

    2011-01-01

    There is an increasing need for automated support for humans monitoring the activity of distributed teams of cooperating agents, both human and machine. We characterize the domain-independent challenges posed by this problem, and describe how properties of domains influence the challenges and their solutions. We will concentrate on dynamic, data-rich domains where humans are ultimately responsible for team behavior. Thus, the automated aid should interactively support effective and timely decision making by the human. We present a domain-independent categorization of the types of alerts a plan-based monitoring system might issue to a user, where each type generally requires different monitoring techniques. We describe a monitoring framework for integrating many domain-specific and task-specific monitoring techniques and then using the concept of value of an alert to avoid operator overload. We use this framework to describe an execution monitoring approach we have used to implement Execution Assistants (EAs) ...

    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.

    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.

    A self-healing application brings itself into a stable state after a failure put the software into an unstable state. For such self-healing software application, finding fix for a previously unseen fault is a grand challenge. Asking the user to provide fixes for every fault is bad for productivity, especially when the users are non-savvy in technical aspect of computing. If failure scenarios come into existence, the user wants the runtime environment to handle those situations autonomically. This paper presents a new technique of finding self-healing actions by matching a fault scenario to already established fault models. By profiling and capturing runtime parameters and execution pathWays, stable execution models are established and later are used to match with an unstable execution scenario. Experimentation and results are presented that showed that even with additional overheads; this technique can prove beneficial for autonomically healing faults and reliving system administrators from mundane troublesho...

    Symbolic execution is a technique which enables automatically generating test inputs (and outputs) exercising a set of execution paths within a program to be tested. If the paths cover a sufficient part of the code under test, the test data offer a representative view of the program's actual behaviour, which notably enables detecting errors and correcting faults. Relational databases are ubiquitous in software, but symbolic execution of pieces of code that manipulate them remains a non-trivia...

  4. [Treatment Options for Executive Dysfunction].

    Science.gov (United States)

    Müller, S V

    2016-09-01

    The concept of executive function is a so-called umbrella concept, so that it includes many different and in some cases mutually contradictory higher-level organizational abilities such as planning, monitoring, inhibition and control of action. Typically, the cause of an executive dysfunction is an underlying lesion in the prefrontal cortex or subcortical regions. Deficits in executive functions appear in the fields of cognition as well as behavior. Diagnosis requires the use of a wide-ranging repertoire of tests and questionnaires making it a time-consuming process. Different therapeutic approaches addressing the diverse symptoms of executive dysfunction, both positive and negative, are available. These include modification and manipulation of the environment and practice of cognitive repetitive procedures. The former are implemented particularly in cases of severely impaired persons. The latter are used in persons in whom cognitive dysfunctions are the dominating symptoms of the disorder.The operational area of therapeutic approaches using paper and pencil as well as computer programs limits them to treatment of cognitive dysfunction. If behavioral disturbances dominate the clinical picture, other procedures should be used.The effectiveness of cognitive therapy of executive dysfunction is well demonstrated according to the criteria of evidence-based medicine (EBM).

    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.

    The execution profile of a distributed-memory parallel program specifies the number of busy processors as a function of time. Periods of homogeneous processor utilization are manifested in many execution profiles. These periods can usually be correlated with the algorithms implemented in the underlying parallel code. Three families of methods for smoothing execution profile data are presented. These approaches simplify the problem of detecting end points of periods of homogeneous utilization. These periods, called phases, are then examined in isolation, and their speedup characteristics are explored. A specific workload executed on an Intel iPSC/860 is used for validation of the techniques described.

  9. 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.

  10. Executive pay and market value sensitivity

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Executive pay relative to that of average workers has risen dramatically worldwide. Such a high level of executive pay raises the question of whether a steep rise in executive pay affects firm value. This study examined the relationship between executive pay and firm value. A panel smooth transition regression model is adopted to determine an optimal level of executive pay that maximizes firm value for a sample of 512 Taiwanese-listed firms over the period 2006-2011. The finding is that when the ratio of executive pay to net income after tax exceeds 2.71%, the firm value increases. The results suggest a correlation between large executive ownership (corresponding to high executive pay and both increased operational efficiencies and firm value. These findings may be useful when contemplating executive compensation policy.

    International Nuclear Information System (INIS)

    Our Institute, with a personnel of 477 (195 research staff ) and 71 Ph.D. students, is presently the largest institute of the Polish Academy of Sciences and one of the largest research institutes in Poland. The scientific staff consists of 129 postdoctoral researchers, 26 Associated Professors (doktor habilitowany) and 40 State - Nominated Professors (see Annex B). The IFJ PAN is financed mainly from the State budget of the Ministry of Science and Higher Education. In 2006 this core financing was about 4.8 MEUR, constituting less than 45 % of the Institute's total budget. The total budget of the Institute for the year 2005 was about 7.0 MEUR but in 2006 increased to over 10.7 MEUR. This rapid increase was mainly caused by the quickly growing income from the international projects, which in 2006 brought a total of more than 2.2 MEUR. In addition, IFJ PAN received substantial support from the grants towards local infrastructure and local equipment, which in 2006 amounted to almost 2.4 MEUR. For further budget information, see Annex C. 2.4 MEUR obtained in 2006 via the structural funds of European Union enabled IFJ PAN the largest purchases of the laboratory equipment in last two decades, especially in the fi eld of materials engineering, ion implantation techniques, surface physics and advanced dosimetric equipment. In addition, the medical equipment for the proton radiotherapy of eye melanoma has been funded by the Ministry of Health and the X-ray microbeam facility by the Polish Foundation of Science. These successes were possible also due to the reorganization of the administration, which elaborated the threefold increased number of tenders. The increasing activity of IFJ PAN at the European level has been awarded by Prof. Sewerynski, the Ministry of Science and High Education by the Prize of the Crystal Brussels in the categories of the Institutes of the Polish Academy of Sciences. The recruitment of the personnel has been significantly modified. All new post

Local governments are established with specific functions to assist the state and federal government to bring about effective rural development and good governance at the grassroots level. Approach: Both fiscal and physical evaluation of the performances of this tier of government in ondo state reveals a low level of performance both in terms of physical development and provision of social welfare services require to enhance the quality of life at the grassroots level. Those responsible for the management of funds at this level ascribed their poor performances to underfunding. This study therefore aims at finding out if truly this claim of underfunding is actually the cause of their poor performance. The study will look at the total capital budget allocation to some selected local governments visa is their actual spending. A sample of nine local governments was selected using random sampling technique based on their settlement pattern. Results: A comparative analysis was done to determine which local government has the largest rate of capital budget execution. The result shows that the local government with the least capital allocation has the largest rate of capital budget execution. Conclusion: The study concludes that the performance of any local government is not a function of availability of huge capital funds but ability to utilize the scarce resources to achieve optimum result.

    Full Text Available This paper examines Dickens’s descriptions of public executions in his letters and early journalism as a context in which to read the final scene of 'A Tale of Two Cities' (1859. 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’.

Executable interface contracts can address these issues but may incur unacceptable overhead. Research into techniques for performance-driven contract enforcement pursues practical solutions to adapting the level of contract enforcement to performance constraints.

  14. An Execution Service for Grid Computing

    Science.gov (United States)

    Smith, Warren; Hu, Chaumin

    2004-01-01

    This paper describes the design and implementation of the IPG Execution Service that reliably executes complex jobs on a computational grid. Our Execution Service is part of the IPG service architecture whose goal is to support location-independent computing. In such an environment, once n user ports an npplicntion to one or more hardware/software platfrms, the user can describe this environment to the grid the grid can locate instances of this platfrm, configure the platfrm as required for the application, and then execute the application. Our Execution Service runs jobs that set up such environments for applications and executes them. These jobs consist of a set of tasks for executing applications and managing data. The tasks have user-defined starting conditions that allow users to specih complex dependencies including task to execute when tasks fail, afiequent occurrence in a large distributed system, or are cancelled. The execution task provided by our service also configures the application environment exactly as specified by the user and captures the exit code of the application, features that many grid execution services do not support due to dflculties interfacing to local scheduling systems.

    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.

    2012-12-01

    The main purpose of the study was to investigate whether baseline myeloperoxidase (MPO) levels are associated with executive cognitive function in individuals with high physical activity. Baseline serum MPO levels of 56 elderly marathon runners and 58 controls were assessed by ELISA. Standardized tests were applied to survey domain-specific cognitive functions. Changes in brain morphology were visualized by magnetic resonance imaging (MRI). High baseline serum MPO levels correlated with worse outcome in tests assessing executive cognitive function in athletes but not in the control group (NAI maze test p<0.05, Trail Making Test ratio p<0.01). In control participants, subcortical white matter hyperintensities were associated with higher scores on the Geriatric Depression Scale (p<0.05), whereas athletes seem to be protected from this effect. During strenuous exercising, MPO as well as its educts may be elevated due to increased oxygen intake and excretion of pro-inflammatory mediators inducing host tissue damage via oxidative stress. This outweighs the potential benefits of physical activity on cognitive function.

    Full Text Available The purpose of this article is to identify and analyze social representations of femininity and masculinity, asreported by women business executives in Brazil. For that, the research resorted to semi-structured interviews of sixty-four executives from seven Brazilian cities. As a technique for data analysis, this research utilized the theoretical and conceptual basis of French discourse analysis. When gender issues become related to the specific qualities of being a woman and a business executive – or to the interfaces that gender may establish with an individual’s work – contradictions may emerge from the construction of a particular thematic. Also, positive and negative aspects of being a female executive exist, namely: (a representations of an executive; (b feminine competency and incompetency; (c dilemmas regarding sensitivity; (d conflicts involving seduction power; (e omissions, prejudice and violence suffered by women at work; and (f motherhood.

    2011-01-01

    Executable Architectures allow the evaluation of system architectures not only regarding their static, but also their dynamic behavior. However, the systems engineering community do not agree on a common formal specification of executable architectures. To close this gap and identify necessary elements of an executable architecture, a modeling language, and a modeling formalism is topic of ongoing PhD research. In addition, systems are generally defined and applied in an operational context to provide capabilities and enable missions. To maximize the benefits of executable architectures, a second PhD effort introduces the idea of creating an executable context in addition to the executable architecture. The results move the validation of architectures from the current information domain into the knowledge domain and improve the reliability of such validation efforts. The paper presents research and results of both doctoral research efforts and puts them into a common context of state-of-the-art of systems engineering methods supporting more agility.

    2004-01-01

    Software verification is recognized as an important and difficult problem. We present a norel framework, based on symbolic execution, for the automated verification of software. The framework uses annotations in the form of method specifications an3 loop invariants. We present a novel iterative technique that uses invariant strengthening and approximation for discovering these loop invariants automatically. The technique handles different types of data (e.g. boolean and numeric constraints, dynamically allocated structures and arrays) and it allows for checking universally quantified formulas. Our framework is built on top of the Java PathFinder model checking toolset and it was used for the verification of several non-trivial Java programs.

    Directory of Open Access Journals (Sweden)

    Bruno eKopp

    2012-06-01

    Full Text Available Executive function is traditionally conceptualized as a set of abilities required to guide behavior toward goals. Here, an integrated theoretical framework for executive function is developed which has its roots in the notion of hierarchical mental models. Further following Duncan (2010a,b, executive function is construed as a hierarchical recursive system of test-operation-test-exit units (Miller, Galanter, and Pribram, 1960. Importantly, it is shown that this framework can be used to model the main regional prefrontal syndromes, which are characterized by apathetic, disinhibited and dysexecutive cognition and behavior, respectively. Implications of these considerations for the neuropsychological assessment of executive function are discussed.

    2014-03-01

    Full Text Available Introduction: The pathophysiologic mechanisms that account for the development and persistence of anorexia nervosa (AN remain unclear. With respect to the neuropsychological functioning, the executive functions have been reported to be altered, especially cognitive flexibility and decision-making processes. Objectives: The aim of this study was to review the current state of the neuropsychological studies focused on anorexia nervosa, especially those highlighting the executive functions. Methods: This was done by means of a searching process covering three relevant electronic databases, as well as an additional search on references included in the analysed papers. Eventually we have to mention other published reviews and a hand-search. Results and discussion: Comparing AN patients and healthy controls the results remain controversial and so remains the comparison of different eating disorders with respect to the neuropsychological dysfunction. The role of variables such as depression, anxiety and obsessionality needs to be clarified. There seems to be some base to state that some commonalities exist in the so-called extreme weight conditions (anorexia, obesity. The link between neuropsychological dysfunction in AN and biomarkers remains unclear. The role of neuropsychological deficits in AN, as initial factors or simply as mere consequences, remains unclear too. The link between the body image disturbances and the neuropsychological dysfunction needs to be clarified. The similarities between the AN neuropsychological dysfunction and that found in other mental disorders may be considered up to date as a mere approach. The same applies to the relationship between the AN patients´ neuropsychological performance and personality or gender.

    Computing optimal stochastic portfolio execution strategies under appropriate risk consideration presents great computational challenge. We investigate a parametric approach for computing optimal stochastic strategies using Monte Carlo simulations. This approach allows reduction in computational complexity by computing coefficients for a parametric representation of a stochastic dynamic strategy based on static optimization. Using this technique, constraints can be similarly handled using appropriate penalty functions. We illustrate the proposed approach to minimize the expected execution cost and Conditional Value-at-Risk (CVaR).

    2014-06-01

    Full Text Available Dynamic code obfuscation technique increases the difficulty of dynamically reverse by the runtime confusion. Path explosion directly affects the efficiency and accuracy of dynamic symbolic analysis. Because of the defect, this paper presents a novel algorithm DDD (Demand-Driven Dynamic Obfuscation Algorithm by using the demand-driven theory of symbolic analysis. First, create a large number of invalid paths to mislead the result of symbolic analysis. Second, according to the demand-driven theory, create a specific execution path to protect the security of software. The design and implementation of the algorithm is based on the current popular and mature SMT (satisfiability model theory, and the experimental effects are tested by Z3 - the SMT solver and Pex - the symbolic execution test tools. The experimental results prove that the algorithm enhance the security of the program.

    With each new rover mission to Mars, rovers are traveling significantly longer distances. This distance increase raises not only the opportunities for science data collection, but also amplifies the amount of environment and rover state uncertainty that must be handled in rover operations. This paper describes how planning, scheduling and execution techniques can be used onboard a rover to autonomously generate and execute rover activities and in particular to handle new science opportunities that have been identified dynamically. We also discuss some of the particular challenges we face in supporting autonomous rover decision-making. These include interaction with rover navigation and path-planning software and handling large amounts of uncertainty in state and resource estimations. Finally, we describe our experiences in testing this work using several Mars rover prototypes in a realistic environment.

    Brain executive function is based in a distributed system whereby prefrontal cortex is interconnected with other cortical. and subcortical loci. Executive function is divided roughly into three interacting parts: affective guidance of responses; linkage among working memory representations; and forming complex behavioral schemata. Neural network models of each of these parts are reviewed and fit into a preliminary theoretical framework.

    The execution distance is a tactic factor that affects mechanical performance and execution technique in taekwondo. This study analyzes the roundhouse kick to the head by comparing the maximum impact force, execution time, and impact time in 3 distances according to the athletes' competition level. It also analyzes the relationship between impact force and weight in each group. It examines whether the execution distance affects the maximum impact force, execution time, and impact time, in each level group or 2 different competition levels. Participants were 27 male taekwondo players (13 medallists and 14 nonmedallists). The medallists executed the roundhouse kick to the head with greater impact force and in a shorter execution time than did the nonmedallists when they kicked from any distance different to their combat distance. However, the results showed that the execution distance is influential in the execution time and impact time in the nonmedallist group. It is considered appropriate to orientate the high-level competitors to train for offensive actions from any distance similar to the long execution distance because it offers equally effectiveness and a greater security against the opponent. Also, practitioners should focus their training to improve time performance because it is more affected by distance than impact force.

    1989-01-01

    If physician executives are to be effective in confronting the environmental turbulence and uncertainty facing their organizations, they must effectively manage their stakeholders. This article extends the stakeholder approach described in the May-June 1989 issue of Physician Executive as a tool for the physician executive in the development of practical strategies to cope with turbulence and uncertainty. We suggest four generic strategies physician executives can use: involve supportive stakeholders, monitor marginal stakeholders, defend against nonsupportive stakeholders, and collaborate with mixed-blessing stakeholders. As an overarching strategy, a physician executive should try to change the organization's relationships with a stakeholder from a less favorable category to a more favorable one. The stakeholder can then be managed using the generic strategy most appropriate for the category.

  12. DECOVALEX II PROJECT Executive Summary

    International Nuclear Information System (INIS)

    DECOVALEX II project started in November 1995 as a continuation of the DECOVALEX I project, which was completed at the end of 1994. The project was initiated by recognising the fact that a proper evaluation of the current capacities of numerical modelling of the coupled T-H-M processes in fractured media is needed not only for small scale, well controlled laboratory test cases such as those studied in DECOVALEX I, but also for less characterised, more complex and realistic in-situ experiments. This executive summary presents the motivation, structure, objectives, approaches, and highlights of the main tasks and main achievements of the DECOVALEX II project from 1995-1999. The main source of the materials came from four technical reports the project prepared by the project Secretariat, which, in turn, were based on numerous progress reports produced by a large number of international research teams over the three and half year period. The editors of this summary, together with the Steering Committee of the DECOVALEX II project, feel very encouraged by the progresses which have been made during the project time and very positive about the usefulness of the achievements reached by the project to the larger international community of scientific research and management of radioactive wastes in different countries. We sincerely hope that continued efforts be made to forward the research carried out in both DECOVALEX I and DECOVALEX II projects so that the disposal of radioactive waste could be managed on a more reliable scientific basis

    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.

    2010-01-01

    The adverse consequences of violence on society are tremendous. The proportion of offenders incarcerated for violent offenses is large, and the cost of keeping these offenders incarcerated is startling. Understanding and treating the causal underpinnings of violent crime is of utmost importance for individuals and society as a whole. Several factors have been identified as potential contributors to violent crime, including cognitive deficits in executive functioning [Hoaken et al., 2007]. To investigate this further, 77 offenders from Fenbrook Institution, a federal facility, were tested on a battery of executive functioning measures. Offenders were found to have broad and pervasive dysfunction in their executive abilities. In addition, specific scores from the battery were found using regression techniques, to predict the frequency and severity of past violent offending but not nonviolent offending. This speaks of the possibility of a new type of correctional rehabilitation program, one that focuses on the rehabilitation of basic executive functions. PMID:20593426

  19. An Improved Kernel Based Extreme Learning Machine for Robot Execution Failures

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Robot execution failures prediction (classification in the robot tasks is a difficult learning problem due to partially corrupted or incomplete measurements of data and unsuitable prediction techniques for this prediction problem with little learning samples. Therefore, how to predict the robot execution failures problem with little (incomplete or erroneous data deserves more attention in the robot field. For improving the prediction accuracy of robot execution failures, this paper proposes a novel KELM learning algorithm using the particle swarm optimization approach to optimize the parameters of kernel functions of neural networks, which is called the AKELM learning algorithm. The simulation results with the robot execution failures datasets show that, by optimizing the kernel parameters, the proposed algorithm has good generalization performance and outperforms KELM and the other approaches in terms of classification accuracy. Other benchmark problems simulation results also show the efficiency and effectiveness of the proposed algorithm.

    2004-10-01

    The executive deficit hypothesis of treated phenylketonuria (PKU) suggests that dopaminergic depletion in the lateral prefrontal cortex leads to selective executive impairment. This was examined by comparing adults with PKU on a lifelong diet with a matched healthy control group. Those with PKU were impaired on selective and sustained attention, working memory (Self-Ordered Pointing), and letter fluency. However, they failed to show differential sensitivity to increased cognitive load on the attentional and working memory tasks, and they did not differ significantly on the remaining executive tasks (rule finding, inhibition, and multitasking). Nor did they differ significantly on recall or recognition memory. Overall, the findings provided little support for the executive deficit hypothesis. A possible explanation in terms of slowed information processing speed is explored.

    2002-01-01

    Experimental studies of normal subjects have shown that the intention to perform an action speeds word recognition for items related to that intention (Goschke & Kuhl, 1993). This phenomenon--the intention superiority effect (ISE)--is thought to be mediated by frontal executive functions. Since schizophrenia is characteristically associated with forms of frontal-executive dysfunction, an impaired ISE might be expected in this patient group. A script-learning paradigm was used to investigate the ISE in 10 schizophrenics who do show evidence of executive dysfunction and in 10 who do not. As predicted, only the former showed an ISE; however, all schizophrenics showed an ISE to words semantically related to the intention. It seems that the ability to form specific intentions is impaired only in schizophrenics with executive dysfunction; however, they retain the ability to form more generalized intentions.

  15. Executive control of attention in narcolepsy.

    Directory of Open Access Journals (Sweden)

    Sophie Bayard

    Full Text Available 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

  18. A Program Transformation for Continuation Call-Based Tabled Execution

    CERN Document Server

    de Guzman, Pablo Chico; Hermenegildo, Manuel V

    2009-01-01

    The advantages of tabled evaluation regarding program termination and reduction of complexity are well known --as are the significant implementation, portability, and maintenance efforts that some proposals (especially those based on suspension) require. This implementation effort is reduced by program transformation-based continuation call techniques, at some efficiency cost. However, the traditional formulation of this proposal by Ramesh and Cheng limits the interleaving of tabled and non-tabled predicates and thus cannot be used as-is for arbitrary programs. In this paper we present a complete translation for the continuation call technique which, using the runtime support needed for the traditional proposal, solves these problems and makes it possible to execute arbitrary tabled programs. We present performance results which show that CCall offers a useful tradeoff that can be competitive with state-of-the-art implementations.

  20. Workflow Planning and Execution - Final Results

    Directory of Open Access Journals (Sweden)

    Ravikant Dewangan

    2016-01-01

    Full Text Available An abstract workflow generation is choosing and configuring with application components to form an abstract workflow. The application components are chosen by examining the specification of their capabilities and checking to see if they can generate the desired data products. They are configured by assigning input files that exist or that may be generated by other application components. The abstract workflow specifies the order in which the components must be executed. A concrete workflow generation is selecting specific resources, files, and additional jobs required to form a concrete workflow that can be executed in the Grid environment. In order to generate a concrete workflow, each component in the abstract workflow is turned into an executable job by specifying the locations of the physical files of the component and data, as well as the resources assigned to the component in the execution environment. Additional jobs may be included in the concrete workflow, for example, jobs that transfer files to the appropriate locations where resources are available to execute the application components.

    Efficient utilization of high-performance computing (HPC) platforms is an important and complex problem. Execution models, abstract descriptions of the dynamic runtime behavior of the execution stack, have significant impact on the utilization of HPC systems. Using a computational chemistry kernel as a case study and a wide variety of execution models combined with load balancing techniques, we explore the impact of execution models on the utilization of an HPC system. We demonstrate a 50 percent improvement in performance by using work stealing relative to a more traditional static scheduling approach. We also use a novel semi-matching technique for load balancing that has comparable performance to a traditional hypergraph-based partitioning implementation, which is computationally expensive. Using this study, we found that execution model design choices and assumptions can limit critical optimizations such as global, dynamic load balancing and finding the correct balance between available work units and different system and runtime overheads. With the emergence of multi- and many-core architectures and the consequent growth in the complexity of HPC platforms, we believe that these lessons will be beneficial to researchers tuning diverse applications on modern HPC platforms, especially on emerging dynamic platforms with energy-induced performance variability.

    This lecture presents the experimental techniques, developed in the last 10 or 15 years, in order to perform a new class of experiments with exotic nuclei, where the reactions induced by these nuclei allow to get information on their structure. A brief review of the secondary beams production methods will be given, with some examples of facilities in operation or under project. The important developments performed recently on cryogenic targets will be presented. The different detection systems will be reviewed, both the beam detectors before the targets, and the many kind of detectors necessary to detect all outgoing particles after the reaction: magnetic spectrometer for the heavy fragment, detection systems for the target recoil nucleus, {gamma} detectors. Finally, several typical examples of experiments will be detailed, in order to illustrate the use of each detector either alone, or in coincidence with others. (author)

    Executive remuneration is a prominent issue of corporate governance in the UK. Executive pay packages are regarded as excessive with no apparent link to company performance. This study examines the regulation of the determination of executive remuneration, especially in quoted companies. The study considers the regulation of the determination of executive remuneration as an important foundation that can potentially link executive pay to company performance. The study considers the principles ...

    Prospective memory is the ability to formulate and carry out actions at the appropriate time or in the appropriate context. This study aimed to identify the effect of hypnosis on prospective memory performance and to analyze the involvement of executive control processes in intention realization in a hypnotically altered state of consciousness. In 1 experiment, manipulating hypnotic instruction in a within-subject fashion, the authors explored the event-based prospective memory performance of 23 volunteers in 3 conditions: baseline, expectation, and execution. The primary result was that executing prospective memory responses, at the same accuracy rate, produced a significantly lower cost of ongoing responses in terms of response latency in the hypnotic state than in wake condition.

    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. PMID:22469209

    2006-11-01

    The causes underlying the correlation between working memory and fluid intelligence remain unknown. There are some researchers who argue that the answer can be found on the presumed executive component of working memory. However, the available empirical evidence is far from conclusive. The present study tested a sample of 229 participants. Intelligence, working memory, and executive functioning were measured by one analytic reasoning test (TRASI), a dual task combining a primary task of deductive reasoning with a secondary task of counting, and the Tower of Hanoi task, respectively. All the 3 measures were computer administered. The results indicate that the shared variance between executive functioning and working memory do not account for the relationship between intelligence and working memory. Some theoretical implications are discussed. PMID:17296123

  14. CTV rendezvous techniques

    Science.gov (United States)

    Jennings, Jerry L.; Anderson, Robert L.

    The cargo transfer vehicle (CTV) requires the capability to perform automated rendezvous with Space Station Freedom (SSF) using onboard sensors and algorithms. The current approach to CTV rendezvous applies techniques developed during the orbital maneuvering vehicle (OMV) program which have been mechanized for automatic, onboard execution. The initial catch up sequence can be described as a passive rendezvous without explicit time of arrival control. The ultimate requirement for this rendezvous technique is to place the CTV on the SSF V-bar axis at some specified downrange distance. The launch vehicle will use yaw steering during orbit injection to achieve the proper phantom plane for nodal biasing. This presentation describes the primary components of the CTV rendezvous scheme.

    Full Text Available Problem statement: This study examines obstacles faced by MBA executive students, regarding five dimensions of obstacle management. The purpose of the research is to assess the relative importance of these dimensions and to establish empirical linkages among obstacles and factors such as overall perception of the organization in terms of obstacle management, span of control of the best management practices, age and success, in order to better understand the influence of those obstacles in light of organizational strategy execution. Approach: A survey questionnaire was administered to 512 managers to study the five pre-defined dimensions regarding obstacles in strategy execution faced by MBA executive students. We used Principal Component Analysis and then ANOVA analysis to examine the empirical linkages between the dimensions of strategy execution identified in previous research and socio-demographic variables such as age, span of control, success, tenure and experience. Results: We found that the dimensions that came first in order of importance, were the obstacles related to emotions, followed by the immediate action, integrity, initiatives and finally the obstacles related to rules. This study also found a linkage between the Emotions dimension (getting a commitment for your objectives and the variable Eval1 (How would you score your organization in terms of managing the five obstacle dimensions? and Eval2 (What would be the score of your organization if the management of the 25 (Obstacles practices had been mastered? Moreover, our results reveal a connection between the immediate action dimension and Eval2. The integrity dimension highlighted the linkage with the Eval1. We showed the tie-ins between the initiatives dimension and the Eval2. The rules dimension reveals three linkages with the socio-demographic variables such as age, Eval1 and Eval3 (I believe that my success in work-related activities is often a matter of luck.

    Best, John R

    2012-09-01

    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.

    2015-01-01

    The matter of modality is controversially discussed in the context of working memory (WM). There is evidence that modality-specific processes are accompanied by amodal processes to some extent. We investigated the relationship between executive-functioning tasks and visual WM (VWM) and were especially interested in the issue of amodal processes. Our correlational analyses suggest modality-independent relations of the tasks. We also aimed to quantify to what extent executive functioning is meaningful for VWM performances. We therefore estimated the relationship between executive tasks and VWM performances in a healthy (n = 710) and a clinical traumatic brain injury sample (n = 151) as well as in the combined total sample. The results indicate a substantial relevance of the verbal task for VWM performances in the total and the clinical sample but a low relevance in the healthy sample. These results could support assumptions of resource-depending differences in the relations of executive functioning and VWM but need further validation due to limitations of our study. PMID:25072205

  18. 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.

  1. Jet Grouting. Control of execution and result parameters. Test fields - Experience in Chile

    International Nuclear Information System (INIS)

    This article emphasizes the importance of Test Fields in project that includes the Jet Grouting technique. In particular, the Chilean experience is analyzed, where the Jet Grouting was first introduced by Pilots Terratest S. A. in the year 2010, only, only in 2011 the first project using jet columns was constructed. The versatilely of this technique allows its use in a wide variety of projects, for example, soil capacity improvement, settlement control, reduction of soil permeability and other environmental applications. Currently, the most common applications are underpinning existing foundations, ground improvement, lateral support of excavations, hydraulic barriers, slope stabilization, liquefaction control, among others. The Jet Grouting is one of the most demanding soil improvement technique and requires excellence in designing and execution engineers and other involved specialist. It is therefore essential to ensure exhaustive control to the execution and final parameters, in order to check that the product- Jet Grouting element-have the design properties, and implement modifications if necessary. Many authors strongly advises that if there is no comparable experience and even if there is, a Test Field of Jet Grouting elements has to be executed in site. This field consists in a nearby area with similar geotechnical conditions of the project, where Jet Grouting test columns will be constructed. This Test Field will allow selecting the most effective execution parameters and verifying that the final product has he correct design properties. (Author)

    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.

Each drug used, the ultrashort-acting barbiturate thiopental, the neuromuscular blocker pancuronium bromide, and the electrolyte potassium chloride, was expected to be lethal alone, while the combination was intended to produce anesthesia then death due to respiratory and cardiac arrest. We sought to determine whether the current drug regimen results in death in the manner intended. METHODS AND FINDINGS: We analyzed data from two US states that release information on executions, North Carolina and California, as well as the published clinical, laboratory, and veterinary animal experience. Execution outcomes from North Carolina and California together with interspecies dosage scaling of thiopental effects suggest that in the current practice of lethal injection, thiopental might not be fatal and might be insufficient to induce surgical anesthesia for the duration of the execution. Furthermore, evidence from North Carolina, California, and Virginia indicates that potassium chloride in lethal injection does not reliably induce cardiac arrest. CONCLUSIONS: We were able to analyze only a limited number of executions. However, our findings suggest that current lethal injection protocols may not reliably effect death through the mechanisms intended, indicating a failure of design and implementation. If thiopental and potassium chloride fail to cause anesthesia and cardiac arrest, potentially aware inmates could die through pancuronium-induced asphyxiation. Thus the conventional view of lethal injection leading to an invariably peaceful and painless death is questionable.

    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.

  7. 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.

    1990-09-01

    The growth of corporate orientation for health care structures, with a focus on bottom-line management, has radically altered the role of nurse executives. With the organization's emphasis on performance, productivity, and results, successful nurse executives are now integrating the management of the delivery of nursing care with the management of complex corporate structures and relationships. The editor of Executive Development discusses the rapidly changing expectations and demands of the contemporary nurse executive's work. The nurse executive's role can be viewed from many perspectives: its scope, its value, its structure, its content. Content--"What does the nurse executive do that makes a real difference?"--is the focus here. PMID:2203884

    Cameron, Jonathan M.

    1991-01-01

    The purpose of this research is to develop an end-to-end system that can be applied to a multibody system in free-fall to analyze its possible motions, save those motions in a database, and design a controller that can execute those motions. A goal is for the process to be highly automated and involve little human intervention. Ideally, the output of the system would be data and algorithms that could be put in ROM to control the multibody system in free-fall. The research applies to more than just robots in space. It applies to any multibody system in free-fall. Mathematical techniques from nonlinear control theory were used to study the nature of the system dynamics and its possible motions. Optimization techniques were applied to plan motions. Image compression techniques were proposed to compress the precomputed motion data for storage. A linearized controller was derived to control the system while it executes preplanned trajectories.

    Interoperability and loose coupling requirements are pushing the next generation of distributed applications towards more decentralized and more dynamic interaction schemes, which the classic requestJresponse communication paradigm can hardly accommodate. Hence, sound foundations and mechanisms for the establishment of unmticiptitteb peer-to-peer interactions across organizational boundaries are of significant importance to upcoming middleware platforms. The Executable Choreography Framework (ECF) is a middleware-level framework that targets dynamic and decentralized service compositions. The ECF combines transparent context propagation with aspect-oriented software composition techniques to dynamically refine the default control and data flow of service invocations. The framework provides a ground for experimentation with dynamic and distributed workflows, and a base to assess their safety and applicability when depioyed across organizational boundaries.

  12. Metamorphic Virus Detection in Portable Executables Using Opcodes Statistical Feature

    CERN Document Server

    Rad, Babak Bashari

    2011-01-01

    Metamorphic viruses engage different mutation techniques to escape from string signature based scanning. They try to change their code in new offspring so that the variants appear non-similar and have no common sequences of string as signature. However, all versions of a metamorphic virus have similar task and performance. This obfuscation process helps to keep them safe from the string based signature detection. In this study, we make use of instructions statistical features to compare the similarity of two hosted files probably occupied by two mutated forms of a specific metamorphic virus. The introduced solution in this paper is relied on static analysis and employs the frequency histogram of machine opcodes in different instances of obfuscated viruses. We use Minkowski-form histogram distance measurements in order to check the likeness of portable executables (PE). The purpose of this research is to present an idea that for a number of special obfuscation approaches the presented solution can be used to i...

    Full Text Available Background: Until very recently mantle field radiotherapy remained the gold standard for the treatment of favorable early-stage Hodgkin′s lymphoma. The classic mantle includes all the major lymph nodes above the diaphragm and extends from the inferior portion of the mandible to the level of the insertion of the diaphragm. Aims: To describe a simple technique that has been devised to treat the mantle field with the help of multileaf collimator and using computed tomography (CT-based treatment planning. Materials and Methods: CT scan was performed with the patient in the supine position and the datasets were transferred to the Eclipse™ treatment planning system. Elekta Precise™ linear accelerator equipped with 40 pairs of multileaf collimator (MLC was used for the execution of the mantle field. The MLC′s shapes were designed to take the shape of the conventional customized blocks used for treatment of mantle field. The anterior mantle field was divided into three separate MLC segments with the collimator kept at 0°. The first MLC segment was shaped to cover the neck, clavicular regions, and mediastinum. The second and the third MLC segments covered the right and left axilla, respectively. The posterior fields were opposed to the anterior subfields in a similar fashion. The dose was prescribed at the midplane, using reference points. Results and Conclusion: The technique described in this study is very simple, easy to implement, and avoids unnecessary delay in the execution of the mantle field. The mantle field can be easily shaped with the multileaf collimators, without any collimator rotation.

    As hospitals reorganize to meet the demand for accessible, cost-effective quality healthcare, nursing's active participation as part of the top management team is vital. The purpose of this study was to describe the leadership profiles of four senior nurse executives and determine their congruence with the theoretical perspectives of the stratified systems theory. A multiple case study methodology was employed to develop individual and group leadership profiles through related experiences obtained during an interview, the organization's expectations based on their job descriptions, and a survey of their self-perceptions of how they spent most of their time. The findings indicated that the executives' leadership behavior was consistent with the theory in that they reported more frequent leadership behaviors at the strategic domain, less activity at the organizational domain, and infrequent activity at the production domain. Individual profiles were uniformly consistent with the group profile. PMID:11140045

    Bazarov, Tahir Y.

    2013-06-01

    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.

  5. Providing Virtual Execution Environments: A Twofold Illustration

    2008-01-01

    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...

    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.

  4. 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

The emergence of motor control coincides with that of EF, hence understanding the relationship between these two domains could have significant implications for early dete...

  6. Can Rhesus Monkey Learn Executive Attention?

    Bramlett-Parker, Jessica; Washburn, David A

    2016-01-01

    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.

    Clinical guidelines (GL) play an important role in medical practice: the one of optimizing the quality of patient care on the basis of evidence based medicine. In order to achieve this goal, the interaction between different agents, who cooperate in the execution of the same GL, is a crucial issue. As a matter of fact, in many cases (e.g. in chronic disorders) the GL execution requires that patient treatment is not performed/completed in the hospital, but is continued in different contexts (e.g. at home, or in the general practitioner's ambulatory), under the responsibility of different agents. In this situation, the correct interaction and communication between the agents themselves is critical for the quality of care, and human resources coordination is a key issue to be addressed by the managers of the involved healthcare services. In this paper we describe how GLARE (Guideline Acquisition, Representation, and Execution), a computerized GL management system, has been extended in order to support such a need. In particular, we have provided: (i) an extension to GL actions representation languages, (ii) proper scheduling and (iii) querying services. By means of these enhancements we aimed at guaranteeing (1) treatment continuity and (2) responsibility assignment support in the various steps of a coordinated and distributed patient care process. We illustrate our approach by means of a practical case study. PMID:23942331

    Hudak, R P; Brooke, P P; Finstuen, K

    2000-01-01

    This analysis reviews a selected body of research that identifies the essential areas of management expertise required of future health care executives. To ensure consistency, six studies are analyzed, utilizing the Delphi technique, to query a broad spectrum of experts in different fields and sites of health care management. The analysis identifies a number of management competencies, i.e., managerial capabilities, which current and aspiring health care executives, in various settings and with differing educational backgrounds, should possess to enhance the probability of their success in current and future positions of responsibility. In addition, this review identifies the skills (technical expertise), knowledge (facts and principles) and abilities (physical, mental or legal power) required to support achievement of these competencies. Leadership and resource management, including cost and finance dimensions, are the highest-rated requisite management competencies. The dominant skills, knowledge and abilities (SKAs) are related to interpersonal skills. The lowest-rated SKAs are related to job-specific, technical skills. Recommendations include the review of this research by formal and continuing education programs to determine the content of their courses and areas for future research. Similarly, current health care executives should assess this research to assist in identifying competency gaps. Lastly, this analysis recommends that the Delphi technique, as a valid and replicable methodology, be applied toward the study of non-executive health care managers, e.g., students, clinicians, mid-level managers and integrated systems administrators, to determine their requisite management competencies and SKAs.

    2005-04-01

    Attention and executive functions were investigated in medicated and unmedicated children with ADHD combined type using a novel selective reaching task. This task involved responding as rapidly as possible to a target while at times having to ignore a distractor. Results indicated that unmedicated children with ADHD showed slow and inaccurate responding. Slow responding reflected problems at the stage of movement preparation but not movement execution. An attentional impairment, rather than a motor planning problem per se, appeared to underlie the slow movement preparation. Inaccurate responding reflected problems with response inhibition and selective attention, impulsivity, set-shifting, and difficulties in maintaining vigilance. Although medicated children with ADHD did not show slow movement preparation, they did show some response inaccuracy, resulting especially from impulsive responding. These findings suggest that ADHD is characterized by slow motor preparation (but not motor execution), and deficits in selective attention, vigilance, and executive functions. Preliminary results suggest that stimulant medication may resolve some of these motor, attentional and executive function deficits.

    2010-01-01

    Departmental executive officers (DEOs), department chairs, and department heads in medical schools are often hired on the basis of their accomplishments in research as well as their skills in administration, management, and leadership. These individuals are also expected to be expert in multiple areas, including negotiation, finance and budgeting, mentoring, and personnel management. At the same time, they are expected to maintain and perhaps even enhance their personal academic standing for the purposes of raising the level of departmental and institutional prestige and for recruiting the next generation of physicians and scientists. In the corporate world, employers understand the importance of training new leaders in requisite skill enhancement that will lead to success in their new positions. These individuals are often provided with extensive executive training to develop the necessary competencies to make them successful leaders. Among the tools employed for this purpose are the use of personal coaches or executive training courses. The authors propose that the use of executive coaching in academic medicine may be of benefit for new DEOs. Experience using an executive coach suggests that this was a valuable growth experience for new leaders in the institution. PMID:20042816

    2016-01-01

    Development of emotion regulation strategy use involves a transition from reliance on suppression during childhood to greater use of reappraisal in adolescence and adulthood-a transition that parallels developmental changes in executive functions. We evaluated the relationship between emotion regulation strategy use and executive functioning in the everyday life of 70 typically developing adolescents who completed the Emotion Regulation Questionnaire for Youth and the Behavior Rating Inventory of Executive Function-Self-Report. Results indicated that greater reliance on reappraisal was associated with better executive functions, while reliance on suppression was related to poorer executive functions. Findings suggest that adolescents who rely on reappraisal may have more cognitive resources to help them remain attentive and well regulated in their daily lives. On the other hand, if better executive functions facilitate the use of reappraisal, adolescents' ability to regulate their emotions could potentially be enhanced via supports for executive functions.

    OLTP (On-Line Transaction Processing) is an important business system sector in various traditional and emerging online services. Due to the increasing number of users, OLTP systems require high throughput for executing tens of thousands of transactions in a short time period. Encouraged by the recent success of GPGPU (General-Purpose computation on Graphics Processors), we propose GPUTx, an OLTP engine performing high-throughput transaction executions on the GPU for in-memory databases. Compared with existing GPGPU studies usually optimizing a single task, transaction executions require handling many small tasks concurrently. Specifically, we propose the bulk execution model to group multiple transactions into a bulk and to execute the bulk on the GPU as a single task. The transactions within the bulk are executed concurrently on the GPU. We study three basic execution strategies (one with locks and the other two lock-free), and optimize them with the GPU features including the hardware support of atomic ope...

    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.

    Portable parallel benchmarks are widely used and highly effective for (a) the evaluation, analysis and procurement of high-performance computing (HPC) systems and (b) quantifying the potential benefits of porting applications for new hardware platforms. Yet, past techniques to synthetically parameterized hand-coded HPC benchmarks prove insufficient for today's rapidly-evolving scientific codes particularly when subject to multi-scale science modeling or when utilizing domain-specific libraries. To address these problems, this work contributes novel methods to automatically generate highly portable and customizable communication benchmarks from HPC applications. We utilize ScalaTrace, a lossless, yet scalable, parallel application tracing framework to collect selected aspects of the run-time behavior of HPC applications, including communication operations and execution time, while abstracting away the details of the computation proper. We subsequently generate benchmarks with identical run-time behavior from the collected traces. A unique feature of our approach is that we generate benchmarks in CONCEPTUAL, a domain-specific language that enables the expression of sophisticated communication patterns using a rich and easily understandable grammar yet compiles to ordinary C + MPI. Experimental results demonstrate that the generated benchmarks are able to preserve the run-time behavior - including both the communication pattern and the execution time - of the original applications. Such automated benchmark generation is particularly valuable for proprietary, export-controlled, or classified application codes: when supplied to a third party. Our auto-generated benchmarks ensure performance fidelity but without the risks associated with releasing the original code. This ability to automatically generate performance-accurate benchmarks from parallel applications is novel and without any precedence, to our knowledge.

    2013-01-01

    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.

The article provides a conceptual mapping and an empirical illustration of three important dynamics of IEs intergovernmental, supranational and transgovernmental dynamics. The study also offers a middle-range organization theory perspective that suggests five independent variables that affect the behavior and roles of IE civil servants. The variables are (H1 the organizational properties of IEs, (H2 the degrees of institutionalization of IEs, (H3 the recruitment procedures of the IEs, (H4 characteristics of the relationships between IEs and external institutions, and finally (H5 demographic characteristics of the IE civil servants. The empirical illustrations are drawn from the European Commission, the OECD Secretariat and the WTO Secretariat. The article highlights that the IEs of the EU, the OECD and the WTO seem to share important behavioral dynamics due to organizational similarities.

    2014-09-01

    The rate of children born prematurely has increased considerably in the last few decades, and their developmental outcome remains of great concern. The literature on the impact of prematurity has reported a wide range of cognitive and behavioral problems that may be related to deficits in executive function (EF) skills. EF refers to a series of high-level processes (selective attention, inhibition, set shifting, working memory, planning, goal setting) that develop throughout childhood and adolescence and play an important role in cognitive and social development as well as in school achievement. EF skills have been linked to the prefrontal cortex, as well as to other neural networks and brain regions including the basal ganglia and cerebellum. This paper focuses on studies related to the development of EF and social behavior in children born preterm. The preschool period is a critical time to perform neuropsychological assessment in addition to IQ testing, and to detect the child's specific needs in order to adapt effective intervention to enhance the development of executive processes in these high-risk children.

    1999-01-01

    As women have been nursing since the earliest days of recorded civilization, so nurses have been associated with health care since the earliest days of recorded medical history. Gender and function have been inextricably woven in ways that created a struggle for success within a male-dominated industry. Nurses, as women, have been undervalued as, until recently, their role in health care has been similarly undervalued. Changing realities in the health care environment have created an opportunity for women's unique skills and talents to be revalued in a way that offers new opportunities for nurses. Teamwork, global thinking, multitasking, creativity, and flexibility are characteristics that have assumed new importance in the marketplace. Nursing leaders possess these attributes, along with a strong clinical foundation that is integrated with knowledge of sound business principles. This combination now positions nurse executives to reach the highest levels of heath care administration. Critical to this achievement is the professional credibility obtained through education at the master's degree level in health care and nursing administration programs that provide the essential tools for professional success. New opportunities for nurse executives afford educators in health care and nursing administration similar opportunities to develop and market programs to this large group of health care professionals who are seeking graduate education in increasing numbers.

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.

  20. Concurrent Single-Executable CCSM with MPH Library

    Energy Technology Data Exchange (ETDEWEB)

    He, Yun; Ding, Chris H.Q.

    2006-05-15

    Community Climate System Model (CCSM) is currently a multi-executable system based on the Multi-Program Multi-Data (MPMD) mechanism. Each component is compiled into a separate executable. MPMD is normally cumbersome in usage and vendor support is sometimes limited or completely unavailable, such as on BlueGene/L. Also smaller groups and institutions would like to run CCSM locally, rather than relying on large computer centers. So, single-executable CCSM is under request. We are developing a multi-executable and single-executable coexisting version of CCSM. In single-executable, each component is organized as a subroutine, which is called from a master program. Different components run simultaneously. This is accomplished by redesigning the top level CCSM structures using the Multi-Program Handshaking (MPH) library.

    Since the commencement of industrial reform in China, most Chinese state-owned enterprises have adopted a deferred executive compensation policy to provide incentives for their management teams. However, the effectiveness of such a policy needs to be evaluated In this paper, we specify a model of deferred executive compensation policy, in which the compensation for executives is contingent on firms 'future revenue. The model suggests that under deferred executive compensation policies, managers exhibit an increasing level of effort in every period. Furthermore, the deferred compensation policy encourages managers to make long-term investments, which might generate revenue even after the termination of managerial contracts.

    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.

    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.

    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

    The development of the SJ Framework for session-based distributed programming is part of recent and ongoing research into integrating session types and practical, real-world programming languages. SJ programs featuring session types (protocols) are statically checked by the SJ compiler to verify the key property of communication safety, meaning that parties engaged in a session only communicate messages, including higher-order communications via session delegation, that are compatible with the message types expected by the recipient. This paper presents current work on security aspects of the SJ Framework. Firstly, we discuss our implementation experience from improving the SJ Runtime platform with security measures to protect and augment communication safety at runtime. We implement a transport component for secure session execution that uses a modified TLS connection with authentication based on the Secure Remote Password (SRP) protocol. The key technical point is the delicate treatment of secure session de...

    This report is an executive summary of a larger report that describes and analyzes the design and operation of Sasol, the South African Fischer-Tropsch coal-liquefaction operation. Sasol produces gasoline for about $0.69 to $0.71/L ($2.60 to $2.70/US gal), along with fuel gas, asphalt, industrial chemicals, fertilizers, and waxes. The product slate is changed to match market demands by altering the plants' operating conditions. Furthermore, redundancies built into plant design have allowed rapid introduction of previously unproven technologies. Close cooperation between the private and public sectors has produced rapid economic as well as technical development of the organization, resulting in large effects on the South African economy and body politic and making Sasol a noteworthy technical enterprise.

  6. Executable UML Modeling For Automotive Embedded Systems

    International Nuclear Information System (INIS)

    Engineers are more and more faced to the hard problem of sophisticated real-time System whereas time to market becomes always smaller. Object oriented modeling supported by UML standard brings effective solutions to such problems. However the possibility to specify real-time aspects of an application are not yet fully satisfactory Indeed, existing industrial proposals supply good answers to concurrency specification problem but they are yet limited regarding to real-time quantitative properties specification of an application. This work aims to construct a complete and consistent UML methodology based on a profile dedicated to automotive embedded Systems modeling and prototyping. This profile contains ail needed extensions to express easily the real-time quantitative properties of an application. Moreover, thanks to the formalization of UML protocol state machines, real-time concepts have been well-integrated in the object oriented paradigm. The main result of this deep integration is that a user is now able to model real-time Systems through the classical object oriented view i.e. without needing any specific knowing in real-time area. In order to answer to an industrial requirement, Systems prototyping (key point for car industry) the ACCORD/UML approach allows also to build executable models of an application. For that purpose, the method supplies a set of rules allow.ng to remove UML ambiguous semantics points, to complete semantics variation points and then to obtain a complete and coherent global model of an application being executable. The work of UML extension and its using formalization realized all along this thesis supplied also a complete and non-ambiguous modeling framework for automotive electronics Systems development. This is also a base particularly well-suited to tackle other facets of the Systems development as automatic and optimized code generation, validation, simulation or tests. (author)

Information Management System hardware configuration as directly influencing the executive design is reviewed. The hardware configuration and generic executive design requirements are considered in detail in a previous report (System Configuration and Executive Requirements Specifications for Reusable Shuttle and Space Station/Base, 9/25/70). This report defines basic system primitives and delineates processes and process control. Supervisor states are considered for describing basic multiprogramming and multiprocessing systems. A high-level computer executive including control of scheduling, allocation of resources, system interactions, and real-time supervisory functions is defined. The description is oriented to provide a baseline for a functional simulation of the computer executive system.

J Strength Cond Res 30(7): 1855-1861, 2016-Caffeine ingestion elicits a variety of physiological effects that may be beneficial to maximal-intensity exercise performance, although its effectiveness and physical mechanism of action enhancing ballistic task performance are unclear. The purpose of this study was to examine the effects of caffeine ingestion on vertical jump height and jump execution in Division I collegiate athletes. The study used a single-blind, randomized, crossover design. Athletes (n = 25) consumed either caffeine (5 mg·kg) or placebo. After a 60-minute waiting period, athletes performed 3 squat jumps (SJ) and 3 countermovement jumps (CMJ) while standing on a force platform. Jump height and execution variables were calculated from mechanography data. In comparison with placebo, caffeine increased SJ height (32.8 ± 6.2 vs. 34.5 ± 6.7 cm; p = 0.001) and CMJ height (36.4 ± 6.9 vs. 37.9 ± 7.4 cm; p = 0.001). Peak force (p = 0.032) and average rate of force development (p = 0.037) were increased during the CMJ in the caffeine trail compared with the control. Time to half peak force was the only execution variable improved with caffeine (p = 0.019) during the SJ. It seems that caffeine affects both height and execution of jumping. Our data indicate that the physical mechanism of jump enhancement is increased peak force production or rate of force development during jumping depending on technique. The physical mechanism of jump enhancement suggests that the ergogenic effects of caffeine may transfer to other ballistic tasks involving the lower-body musculature in collegiate athletes.

On the basis of governance rule and also Iran business rule, the companies in Tehran stock exchange should abide about the combination of the board and also interrelated committee and protect minority stockholders against majority. In order to do this research, the information of the companies in financial statements and the reports of the Tehran stock exchangehave been used. For the measurements of the earnings smoothing John's adjusted model has been used and for the measurement of the concentration of company's ownership "Herfindal" and "Hireshman" has been used. The choice of the companies is randomly and the confidence interval has been considered %95 .For research ,observe 435 corporation- year and time period is 2005 – 2010. The results of the research reveal don'tmeaningful relationship of non executive directors and discretionary accrual accounting and the relationship is a positive. In companies which the concentration of ownership is high, management and earnings manipulationis also high and has a meaningful relationship and negative with these variables. The segregation of the companies into government and private causes to different the results. In private companies the concentration of the ownership is little and the statistical mean of discretionary accrual accounting items is low and non executive directors ratio is low but in governmental corporations statistical mean of discretionary accrual accounting item is high and ratio of corporations that has internal auditing is high to private corporations .Further more almost of non executive directors in Iranian corporation have nonfinancial technique and knowledge and ratio of them in board corporation is higher than executive directors.

    2011-01-01

    Full Text Available Metamorphic viruses  engage different mutation techniques to escape from string signature based scanning. They try to change their code in new offspring so that the variants appear non-similar and have no common sequences of string as signature. However, all versions of a metamorphic virus have similar task and performance. This obfuscation process helps to keep them safe from the string based signature detection. In this study, we make use of instructions statistical features to compare the similarity of two hosted files probably occupied by two mutated forms of a specific metamorphic virus. The introduced solution in this paper is relied on static analysis and employs the frequency histogram of machine opcodes in different instances of obfuscated viruses. We use Minkowski-form histogram distance measurements in order to check the likeness of portable executables (PE. The purpose of this research is to  present an idea that for  a number of special  obfuscation approaches the presented solution can be  used to identify morphed copies of a file. Thus, it can be applied by antivirus scanner to recognize different versions of a metamorphic virus.

    Large computing clusters used for scientific processing suffer from systemic failures when operated over long continuous periods for executing workflows. Diagnosing job problems and faults leading to eventual failures in this complex environment is difficult, specifically when the success of an entire workflow might be affected by a single job failure. In this paper, we introduce a model-based, hierarchical, reliable execution framework that encompass workflow specification, data provenance, execution tracking and online monitoring of each workflow task, also referred to as participants. The sequence of participants is described in an abstract parameterized view, which is translated into a concrete data dependency based sequence of participants with defined arguments. As participants belonging to a workflow are mapped onto machines and executed, periodic and on-demand monitoring of vital health parameters on allocated nodes is enabled according to pre-specified rules. These rules specify conditions that must be true pre-execution, during execution and post-execution. Monitoring information for each participant is propagated upwards through the reflex and healing architecture, which consists of a hierarchical network of decentralized fault management entities, called reflex engines. They are instantiated as state machines or timed automatons that change state and initiate reflexive mitigation action(s) upon occurrence of certain faults. We describe how this cluster reliability framework is combined with the workflow execution framework using formal rules and actions specified within a structure of first order predicate logic that enables a dynamic management design that reduces manual administrative workload, and increases cluster-productivity.

  3. Modelling Limit Order Execution Times from Market Data

    Science.gov (United States)

    Kim, Adlar; Farmer, Doyne; Lo, Andrew

    2007-03-01

    Although the term ``liquidity'' is widely used in finance literatures, its meaning is very loosely defined and there is no quantitative measure for it. Generally, ``liquidity'' means an ability to quickly trade stocks without causing a significant impact on the stock price. From this definition, we identified two facets of liquidity -- 1.execution time of limit orders, and 2.price impact of market orders. The limit order is an order to transact a prespecified number of shares at a prespecified price, which will not cause an immediate execution. On the other hand, the market order is an order to transact a prespecified number of shares at a market price, which will cause an immediate execution, but are subject to price impact. Therefore, when the stock is liquid, market participants will experience quick limit order executions and small market order impacts. As a first step to understand market liquidity, we studied the facet of liquidity related to limit order executions -- execution times. In this talk, we propose a novel approach of modeling limit order execution times and show how they are affected by size and price of orders. We used q-Weibull distribution, which is a generalized form of Weibull distribution that can control the fatness of tail to model limit order execution times.

    BACKGROUND: Recent researches demonstrate that damage of executive function is an early manifestation of vascular cognitive disorder.OBJECTIVE: To investigate the executive functions of patients with transient ischemic attack (TIA).DESIGN: Case control.SETTING: Department of Neurology, the First Affiliated Hospital of Xinxiang Medical College.PARTICIPANTS: A total of 83 TIA patients (46 males and 37 females, aged 32 - 74 years) were selected from Department of Neurology, the First Affiliated Hospital of Xinxiang Medical College from July 2005 to December 2006. The diagnosis of TIA was established by the criteria of cerebrovascular diseases made by the Fourth National Cerebrovascular Disease Meeting. In these cases, forty-five patients (54%) were involved in internal carotid artery, and thirty-eight patients (46%) were involved in vertebral basilar system.Fifty healthy adults (Control group: 28 males and 22 females, aged 32 - 74 years) were chosen from retiree in community and family of patients. All of them were right-handedness, without cerebrovascular disease,cerebral trauma, inborn oligophrenia, and hearing and visual disorders; also they had no anxiety and depression nearly one week. In addition, all the subjects cooperated with examination.METHODS: After TIA diagnosis, all patients received neuropsychological examination, including attention and inhibition, working memory, flexibility, planning and diversion, based on Stroop tests (C and CW) and the Wisconsin card sorting tests (WCST). ① WCST test: The edition revised by Nelson was used. We would take the times of sorting, incorrect response, persistent incorrect response, and randomly incorrect response as the index of evaluation. ② Stroop tests: The edition revised by Trenarry was used and this test had two types: form color and form color-word. Their incorrect response and response time were recorded for data analysis in the end.MAIN OUTCOME MEASURES: Results of WCST test and Stroop tests.RESULTS: A

    1995-12-01

    The design of 3D-conformal dose distributions for targets with concave outlines is a technical challenge in conformal radiotherapy. For these targets, it is impossible to find beam incidences for which the target volume can be isolated from the tissues at risk. Commonly occurring examples are most thyroid cancers and the targets located at the lower neck and upper mediastinal levels related to some head and neck. A solution to this problem was developed, using beam intensity modulation executed with a multileaf collimator by applying a static beam-segmentation technique. The method includes the definition of beam incidences and beam segments of specific shape as well as the calculation of segment weights. Tests on Sherouse`s GRATISTM planning system allowed to escalate the dose to these targets to 65-70 Gy without exceeding spinal cord tolerance. Further optimization by constrained matrix inversion was investigated to explore the possibility of further dose escalation.

    Curran, Connie R; Totten, Mary K

    2010-01-01

    Making sure the relative roles of the board and management are clear and agreed upon is becoming more important as market and regulatory forces compel boards to govern at levels of detail once considered micromanagement, but are now required and necessary in the current environment of heightened governance accountability. A clear understanding of each other's roles and responsibilities is step one in building a solid partnership between the board and chief executive. A second element of building a strong foundation for the board-CEO relationship is taking time early on to establish mutual expectations about working together. The board's responsibilities in CEO performance management and compensation include setting performance expectations and goals that are clear and measurable and coaching and motivating the CEO. When a CEO fails, one of the most important steps for the board to take is to look in the mirror and commit to the rigorous due diligence needed to avoid future mistakes. Boards should always have CEO succession on their agenda. PMID:21158257

  1. Transportation systems analyses: Volume 1: Executive Summary

    Science.gov (United States)

    1993-05-01

    The principal objective of this study is to accomplish a systems engineering assessment of the nation's space transportation infrastructure. This analysis addresses the necessary elements to perform man delivery and return, cargo transfer, cargo delivery, payload servicing, and the exploration of the Moon and Mars. Specific elements analyzed, but not limited to, include the Space Exploration Initiative (SEI), the National Launch System (NLS), the current expendable launch vehicle (ELV) fleet, ground facilities, the Space Station Freedom (SSF), and other civil, military and commercial payloads. The performance of this study entails maintaining a broad perspective on the large number of transportation elements that could potentially comprise the U.S. space infrastructure over the next several decades. To perform this systems evaluation, top-level trade studies are conducted to enhance our understanding of the relationships between elements of the infrastructure. This broad 'infrastructure-level perspective' permits the identification of preferred infrastructures. Sensitivity analyses are performed to assure the credibility and usefulness of study results. This executive summary of the transportation systems analyses (TSM) semi-annual report addresses the SSF logistics resupply. Our analysis parallels the ongoing NASA SSF redesign effort. Therefore, there could be no SSF design to drive our logistics analysis. Consequently, the analysis attempted to bound the reasonable SSF design possibilities (and the subsequent transportation implications). No other strategy really exists until after a final decision is rendered on the SSF configuration.

  3. Secure Execution of Distributed Session Programs

    2011-10-01

    Full Text Available The development of the SJ Framework for session-based distributed programming is part of recent and ongoing research into integrating session types and practical, real-world programming languages. SJ programs featuring session types (protocols are statically checked by the SJ compiler to verify the key property of communication safety, meaning that parties engaged in a session only communicate messages, including higher-order communications via session delegation, that are compatible with the message types expected by the recipient. This paper presents current work on security aspects of the SJ Framework. Firstly, we discuss our implementation experience from improving the SJ Runtime platform with security measures to protect and augment communication safety at runtime. We implement a transport component for secure session execution that uses a modified TLS connection with authentication based on the Secure Remote Password (SRP protocol. The key technical point is the delicate treatment of secure session delegation to counter a previous vulnerability. We find that the modular design of the SJ Runtime, based on the notion of an Abstract Transport for session communication, supports rapid extension to utilise additional transports whilst separating this concern from the application-level session programming task. In the second part of this abstract, we formally prove the target security properties by modelling the extended SJ delegation protocols in the pi-calculus.

    Sensitive and selective detection techniques are of crucial importance for capillary electrophoresis (CE), microfluidic chips, and other microfluidic systems. Electrochemical detectors have attracted considerable interest for microfluidic systems with features that include high sensitivity, inherent miniaturization of both the detection and control instrumentation, low cost and power demands, and high compatibility with microfabrication technology. The commonly used electrochemical detectors can be classified into three general modes: conductimetry, potentiometry, and amperometry.

    1998-01-01

    MFIX (Multiphase Flow with Interphase eXchanges) is a general-purpose hydrodynamic model for describing chemical reactions and heat transfer in dense or dilute fluid-solids flows, which typically occur in energy conversion and chemical processing reactors. The calculations give time-dependent information on pressure, temperature, composition, and velocity distributions in the reactors. The theoretical basis of the calculations is described in the MFIX Theory Guide. Installation of the code, setting up of a run, and post-processing of results are described in MFIX User`s manual. Work was started in April 1996 to increase the execution speed and accuracy of the code, which has resulted in MFIX 2.0. To improve the speed of the code the old algorithm was replaced by a more implicit algorithm. In different test cases conducted the new version runs 3 to 30 times faster than the old version. To increase the accuracy of the computations, second order accurate discretization schemes were included in MFIX 2.0. Bubbling fluidized bed simulations conducted with a second order scheme show that the predicted bubble shape is rounded, unlike the (unphysical) pointed shape predicted by the first order upwind scheme. This report describes the numerical technique used in MFIX 2.0.

    Working Group 8 discussed oil and gas pipeline integrity issues with particular reference to inspection tools and techniques used by the upstream and downstream pipeline industries. The group addressed other options besides in-line inspection (ILI) for integrity assessments and presented emerging concerns with non-piggable piping. Inspection techniques such as hydrotesting, direct assessment, cameras, and X-ray imaging were reviewed. The actions taken in response to recommendations from past workshops were also presented, including measures to improve standardization of reporting practices. It was noted that tools currently available have limitations that vary with the environment in which they are used, the depth to which the pipeline is buried, and the size and orientation of the pipeline. It was determined that economics plays a key role in the selection of pipeline inspection techniques, and that failure modes should be considered when choosing inspection techniques. Given that environmental consequences are different for natural gas and liquid pipelines, this may influence the choice of inspection needed in environmentally sensitive areas. It was determined that new technologies have yet to gain the confidence of industry and that while some existing technologies (such as cameras) can provide data, they are not suitable as the only tool used in an integrity assessment. The accuracy of inspections was found to depend on the tools, methods and personnel, with variation in accuracy depending primarily on personnel. It was concluded that research and development of new inspection techniques should continue. tabs., figs.

  9. Competence to be executed: An ethical analysis post Panetti.

    Science.gov (United States)

    Weinstock, Robert; Leong, Gregory B; Silva, J Arturo

    2010-01-01

    Competence to be executed evaluations in effect can prevent an execution or remove the last meaningful impediment to it. Forensic psychiatrists have primary duties to the legal system and truth and honesty, but like all other areas of medical consultation also should balance conflicting secondary traditional medical ethical duties. Participation in a legally authorized execution so violates medical roles, that it is ethically prohibited by the American Medical Association and American Psychiatric Association. This prohibition includes treatment intended to restore competence to be executed. However, despite the primary treatment intent otherwise being appropriate ethically, like relieving suffering or fostering prison safety, if competence to be executed almost predictably would be a treatment result, at least the risk of this result should be considered ethically as if it were intended. In contrast, competence to be executed assessments can be ethical. Diamond's approach of performing honest evaluations only for the defense is an ethical option for such assessments. However, it is challenging to persuade judges and juries of the objectivity of such honest legitimate assessments. Most practitioners therefore likely would consider assessing competence to be executed for either side. This ethically hazardous position necessitates sensitivity to potentially seriously conflicting duties and roles. PMID:20669246

  10. 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.

    2012-10-01

    The Business Process Execution Language (BPEL) has become a popular choice for orchestrating and executing workflows in the Web environment. As one special kind of scientific workflow, geospatial Web processing workflows are data-intensive, deal with complex structures in data and geographic features, and execute automatically with limited human intervention. To enable the proper execution and coordination of geospatial workflows, a specially enhanced BPEL execution engine is required. BPELPower was designed, developed, and implemented as a generic BPEL execution engine with enhancements for executing geospatial workflows. The enhancements are especially in its capabilities in handling Geography Markup Language (GML) and standard geospatial Web services, such as the Web Processing Service (WPS) and the Web Feature Service (WFS). BPELPower has been used in several demonstrations over the decade. Two scenarios were discussed in detail to demonstrate the capabilities of BPELPower. That study showed a standard-compliant, Web-based approach for properly supporting geospatial processing, with the only enhancement at the implementation level. Pattern-based evaluation and performance improvement of the engine are discussed: BPELPower directly supports 22 workflow control patterns and 17 workflow data patterns. In the future, the engine will be enhanced with high performance parallel processing and broad Web paradigms.

    Full Text Available Background. Patients with clinically isolated syndrome (CIS demonstrate brain hemodynamic changes and also suffer from difficulties in processing speed, memory, and executive functions. Objective. To explore whether brain hemodynamic disturbances in CIS patients correlate with executive functions. Methods. Thirty CIS patients and forty-three healthy subjects, matched for age, gender, education level, and FSIQ, were administered tests of visuomotor learning and set shifting ability. Cerebral blood volume (CBV, cerebral blood flow (CBF, and mean transit time (MTT values were estimated in normal-appearing white matter (NAWM and normal-appearing deep gray Matter (NADGM structures, using a perfusion MRI technique. Results. CIS patients showed significantly elevated reaction time (RT on both tasks, while their CBV and MTT values were globally increased, probably due to inflammatory vasodilation. Significantly, positive correlation coefficients were found between error rates on the inhibition condition of the visuomotor learning task and CBV values in occipital, periventricular NAWM and both thalami. On the set shifting condition of the respective task significant, positive associations were found between error rates and CBV values in the semioval center and periventricular NAWM bilaterally. Conclusion. Impaired executive function in CIS patients correlated positively with elevated regional CBV values thought to reflect inflammatory processes.

    Meditation improves executive functions such as attention and working memory processes. However, it remains unclear to what extent contextual effects contribute to these improvements, since the role of meditation-associated expectations has not been investigated so far. In a randomized, single-blind, deceptive, between-subject design we compared the impact of short-term meditation (MG) on executive functioning with an expectation (ECG) and a passive control group (CG) as well as the effect of positive and negative outcome expectations. Fifty-nine healthy meditation-naïve volunteers participated on three consecutive days (20 min/session). Five groups were examined: 2 MGs, 2 ECGs and 1 CG. While one MG and one ECG were given positive suggestions concerning the effect of meditation on attention, the other two groups were given negative suggestions. MGs practised a focused attention meditation technique; ECGs were told that they were practising meditation but were given instructions for a sham meditation. CG participants sat in silence with their eyes closed. Interference control (Stroop task), selective sustained attention (d2 task), figural and verbal fluency measures of executive functions were assessed. Results indicate that suggestions have a substantial impact on interference control and verbal fluency, with positive suggestions leading to an increase in performance, whereas negative suggestions impeded improvement. This proof of concept study demonstrates the importance of the implementation of a credible ECG to elucidate context effects in meditation processes. It also indicates that suggestions can modulate the small effect of meditation on verbal fluency.

    The brain is an inherently dynamic system, and executive cognition requires dynamically reconfiguring, highly evolving networks of brain regions that interact in complex and transient communication patterns. However, a precise characterization of these reconfiguration processes during cognitive function in humans remains elusive. Here, we use a series of techniques developed in the field of "dynamic network neuroscience" to investigate the dynamics of functional brain networks in 344 healthy subjects during a working-memory challenge (the "n-back" task). In contrast to a control condition, in which dynamic changes in cortical networks were spread evenly across systems, the effortful working-memory condition was characterized by a reconfiguration of frontoparietal and frontotemporal networks. This reconfiguration, which characterizes "network flexibility," employs transient and heterogeneous connectivity between frontal systems, which we refer to as "integration." Frontal integration predicted neuropsychological measures requiring working memory and executive cognition, suggesting that dynamic network reconfiguration between frontal systems supports those functions. Our results characterize dynamic reconfiguration of large-scale distributed neural circuits during executive cognition in humans and have implications for understanding impaired cognitive function in disorders affecting connectivity, such as schizophrenia or dementia.

  19. A Reconfigurable Functional Unit with Conditional Execution for Multi-Exit Custom Instructions

    Noori, Hamid; Mehdipour, Farhad; Inoue, Koji; Murakami, Kazuaki

    Encapsulating critical computation subgraphs as application-specific instruction set extensions is an effective technique to enhance the performance of embedded processors. However, the addition of custom functional units to the base processor is required to support the execution of these custom instructions. Although automated tools have been developed to reduce the long design time needed to produce a new extensible processor for each application, short time-to-market, significant non-recurring engineering and design costs are issues. To address these concerns, we introduce an adaptive extensible processor in which custom instructions are generated and added after chip-fabrication. To support this feature, custom functional units (CFUs) are replaced by a reconfigurable functional unit (RFU). The proposed RFU is based on a matrix of functional units which is multi-cycle with the capability of conditional execution. A quantitative approach is utilized to propose an efficient architecture for the RFU and fix its constraints. To generate more effective custom instructions, they are extended over basic blocks and hence, multiple exits custom instructions are proposed. Conditional execution has been added to the RFU to support the multi-exit feature of custom instructions. Experimental results show that multi-exit custom instructions enhance the performance by an average of 67% compared to custom instructions limited to one basic block. A maximum speedup of 4.7, compared to a general embedded processor, and an average speedup of 1.85 was achieved on MiBench benchmark suite.

    Clean production does not only make the sustainable development possible through preventing the deterioration of the environmental pollution from the expansion of industrialization but also enhance the company's competitiveness. Clean production is required by all industrial fields but is the most important in chemical industry. The Government has made efforts to change the domestic industrial structure to the environmental-friendly structure through developing the research. However, the domestic industry has not yet activated overall except some large companies, which has concretized the activation of clean production. Especially, the medium and small companies are more sluggish due to the inferiority of capital and technology. With recognizing that the main body of clean production is a company, the effort based on the Government and the academic world, without companies' positive, will cannot help being limited in effects. Therefore, it is necessary to trigger the schemes that urge the companies' motivation to show the effects from the support that have concentrated in hardware like technology until now. It seems to be very important that the guidebook for clean production, which a company can easily adopt, is developed and spread. This report provides the guidebook for clean production that managers and engineers can easily understand and approach in a producing field and presents the scheme to promote clean production, for chemical industry that is seriously required clean production. Even if the presented contents are not perfect, they can be applied to the development of the Government's policy and the administrative activities of companies for clean production as a useful data. 53 refs., 5 figs., 30 tabs.

    Gallant, Sara N

    2016-02-01

    This paper focuses on evidence for mindfulness meditation-related benefits to executive functioning, processes important for much of human volitional behaviour. Miyake et al. (2000) have shown that executive functions can be fractionated into three distinct domains including inhibition, working memory updating, and mental set shifting. Considering these separable domains, it is important to determine whether the effects of mindfulness can generalize to all three sub-functions or are specific to certain domains. To address this, the current review applied Miyake et al.'s (2000) fractionated model of executive functioning to the mindfulness literature. Empirical studies assessing the benefits of mindfulness to measures tapping the inhibition, updating, and shifting components of executive functioning were examined. Results suggest a relatively specific as opposed to general benefit resulting from mindfulness, with consistent inhibitory improvement, but more variable advantages to the updating and shifting domains. Recommendations surrounding application of mindfulness practice and future research are discussed. PMID:26784917

    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.

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

    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.

  8. Flouting the demands of justice? Physician participation in executions.

    Science.gov (United States)

    Kadlac, Adam

    2014-10-01

    Those who argue against physician participation in state mandated executions tend to bracket the question of whether the death penalty should be abolished. I argue that these issues cannot be neatly separated. On the one hand, if justice demands that some criminals be executed for their crimes, then there can be no ethical or moral barrier to the participation of physicians in the execution process. On the other hand, I contend that the testimony and expertise of the medical community is a necessary component of any fruitful reflection on whether capital punishment is, in fact, just. Thus, although the justice of capital punishment may render it permissible for physicians to participate in the execution process, the experience of physicians also sheds important light on whether the death penalty is morally justified.

    Executive functioning is widely targeted when human cognition is assessed, but there is little consensus on how it should be operationalized and measured. Recognizing the difficulties associated with establishing standard operational definitions of executive functioning, the National Institute of Neurological Disorders and Stroke entered into a contract with the University of California-San Francisco to develop psychometrically robust executive measurement tools that would be accepted by the neurology clinical trials and clinical research communities. This effort, entitled Executive Abilities: Measures and Instruments for Neurobehavioral Evaluation and Research (EXAMINER), resulted in a series of tasks targeting working memory, inhibition, set shifting, fluency, insight, planning, social cognition and behavior. We describe battery conceptualization and development, data collection, scale construction based on item response theory, and lay the foundation for studying the battery's utility and validity for specific assessment and research goals.

  10. An Expressive Language and Efficient Execution System for Software Agents

    CERN Document Server

    Barish, G; 10.1613/jair.1548

    2011-01-01

    Software agents can be used to automate many of the tedious, time-consuming information processing tasks that humans currently have to complete manually. However, to do so, agent plans must be capable of representing the myriad of actions and control flows required to perform those tasks. In addition, since these tasks can require integrating multiple sources of remote information ? typically, a slow, I/O-bound process ? it is desirable to make execution as efficient as possible. To address both of these needs, we present a flexible software agent plan language and a highly parallel execution system that enable the efficient execution of expressive agent plans. The plan language allows complex tasks to be more easily expressed by providing a variety of operators for flexibly processing the data as well as supporting subplans (for modularity) and recursion (for indeterminate looping). The executor is based on a streaming dataflow model of execution to maximize the amount of operator and data parallelism possib...

    In this paper, I elicit risk attitudes of U.S. executives by calibrating a subjective option valuation model for option exercising data (1996 to 2008), yielding approximately 65,000 values of relative risk aversion (RRA) for almost 7,000 executives. The observed behavior is generally consistent...... with moderate risk aversion and a median (mean) RRA close to one (three). Values are validated for chief executive officers (CEOs) by testing theory-based predictions on the influence of individual characteristics on risk preferences such as gender, marital status, religiosity, and intelligence. Senior managers...... such as CEOs, presidents, and chairpersons of the boards of directors are significantly less risk averse than non-senior executives. RRA heterogeneity is strongly correlated with sector membership and firm-level variables such as size, performance, and capital structure. Alternative factors influencing option...

    2014-12-01

    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.

    2016-01-01

    Split-execution computing leverages the capabilities of multiple computational models to solve problems, but splitting program execution across different computational models incurs costs associated with the translation between domains. We analyze the performance of a split-execution computing system developed from conventional and quantum processing units (QPUs) by using behavioral models that track resource usage. We focus on asymmetric processing models built using conventional CPUs and a family of special-purpose QPUs that employ quantum computing principles. Our performance models account for the translation of a classical optimization problem into the physical representation required by the quantum processor while also accounting for hardware limitations and conventional processor speed and memory. We conclude that the bottleneck in this split-execution computing system lies at the quantum-classical interface and that the primary time cost is independent of quantum processor behavior.

    This study examines language abilities of children with attention-deficit hyperactivity disorder (ADHD) and compares these abilities to those of children with specific language impairment (SLI) and typically developing children. Executive functioning, an umbrella term for various higher order cognitive processes, and responsible for goal-directed behaviour, is also examined. Moreover, the study explores the possibility that executive dysfunctioning may be specifically linked to pragmatic lang...

    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.

    2015-03-01

    Full Text Available Orientation: The relationship between Chief Executive Officer (CEO remuneration and organisation performance has been a topic of close scrutiny, especially since the global financial crisis. Optimal contracting relies on the premise that effective incentives will link organisation financial performance and CEO remuneration in ways that will be in the best interests of both shareholders and CEOs.Research purpose: The purpose of this research study was to investigate the relationship between CEO remuneration and organisation performance in South Africa between 2006 and 2012 and to determine whether the two constructs were positively correlated.Motivation for the study: The study provides an evidenced-based understanding of the nature of the CEO pay-performance relationship in South Africa. Understanding this relationship is critical to finding a suitable model to structure executive remuneration that will protect shareholders from over-remunerating executives in times of economic appreciation, whilst protecting executives from being underpaid in times of economic depreciation.Method: The financial results and CEO remuneration of 21 of the top 40 listed companies on the Johannesburg Stock Exchange were analysed for the period 2006–2012. The research was a quantitative, archival study. The primary statistical techniques used in the study were correlation analysis and multiple regression analysis.Main findings: The primary finding of the current research indicates that between 2006 and 2012 organisation executives have noticeably been moving away from focusing on short-termincentives, which are categorised as performance-related elements of remuneration packages.Based on these findings, it is evident that the relationship between executive remuneration and organisational financial performance has been experiencing a decline, especially since the 2008 global financial crisis. The decline has predominantly been due to a move away from performance

  11. Dose Reduction Techniques

    International Nuclear Information System (INIS)

    As radiation safety specialists, one of the things we are required to do is evaluate tools, equipment, materials and work practices and decide whether the use of these products or work practices will reduce radiation dose or risk to the environment. There is a tendency for many workers that work with radioactive material to accomplish radiological work the same way they have always done it rather than look for new technology or change their work practices. New technology is being developed all the time that can make radiological work easier and result in less radiation dose to the worker or reduce the possibility that contamination will be spread to the environment. As we discuss the various tools and techniques that reduce radiation dose, keep in mind that the radiological controls should be reasonable. We can not always get the dose to zero, so we must try to accomplish the work efficiently and cost-effectively. There are times we may have to accept there is only so much you can do. The goal is to do the smart things that protect the worker but do not hinder him while the task is being accomplished. In addition, we should not demand that large amounts of money be spent for equipment that has marginal value in order to save a few millirem. We have broken the handout into sections that should simplify the presentation. Time, distance, shielding, and source reduction are methods used to reduce dose and are covered in Part I on work execution. We then look at operational considerations, radiological design parameters, and discuss the characteristics of personnel who deal with ALARA. This handout should give you an overview of what it takes to have an effective dose reduction program

    Full Text Available The world is surrounded by technology and Internet with extreme dynamic changes day by day in it.Due to that quintillion bytes of data is created. Source of this data is in the form of petabytes and zettabytes,which is known as Big data.Examples of such data are climate information, trajectory information, transaction records, web site usage data etc .As this data is in the abundant form so that not easy to process and require more time to execute.Hadoop is only scalable that is it can reliably store and process petabytes. Hadoop plays an important role in processing and handling big data It includes MapReduce – offline computing engine, HDFS – Hadoop Distributed file system, HBase – online data access.Map Reduce functions as dividing input files into chunks and processing these in a series of parallelizable steps., mapping and reducing constitute the essential phases for a Map Reduce job. As this freamework provides solution for large data nodes by providing distributed environment. Moving all input data to a single datacenter before processing the data is expensive. Hence we concentrate on geographical distribution of geo-distributed data for sequential execution of map reduce jobs to optimize the execution time. But it is observed from various results that mapping and reducing function is not sufficient for all type of data processing. The fixed execution strategy of map reduce program is not optimal for many task as it does not know about the behavior of the functions. Thus, to overcome these issues, we are enhancing our proposed work with parallelization contracts. These contracts help to capture a reasonable amount of semantics for executing any type of task with reduced time consumption. The parallelization contracts include input and output contract which includes the constraints and functions of data execution The main aim of this paper is to discuss various known Map reduce technology techniques available for geodistributed data

    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.

    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 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.

    This report documents a prototype tool developed to investigate the use of visualization and virtual reality technologies for improving software surety confidence. The tool is utilized within the execution phase of the software life cycle. It provides a capability to monitor an executing program against prespecified requirements constraints provided in a program written in the requirements specification language SAGE. The resulting Software Attribute Visual Analysis Tool (SAVAnT) also provides a technique to assess the completeness of a software specification. The prototype tool is described along with the requirements constraint language after a brief literature review is presented. Examples of how the tool can be used are also presented. In conclusion, the most significant advantage of this tool is to provide a first step in evaluating specification completeness, and to provide a more productive method for program comprehension and debugging. The expected payoff is increased software surety confidence, increased program comprehension, and reduced development and debugging time.

    Executive functions are often considered lynchpin "frontal lobe tasks", despite accumulating evidence that a broad network of anterior and posterior brain structures supports them. Using a latent variable modelling approach, we assessed whether prefrontal grey matter volumes independently predict executive function performance when statistically differentiated from global atrophy and individual non-frontal lobar volume contributions. We further examined whether fronto-parietal white matter microstructure underlies and independently contributes to executive functions. We developed a latent variable model to decompose lobar grey matter volumes into a global grey matter factor and specific lobar volumes (i.e. prefrontal, parietal, temporal, occipital) that were independent of global grey matter. We then added mean fractional anisotropy (FA) for the superior longitudinal fasciculus (dorsal portion), corpus callosum, and cingulum bundle (dorsal portion) to models that included grey matter volumes related to cognitive variables in previous analyses. Results suggested that the 2-factor model (shifting/inhibition, updating/working memory) plus an information processing speed factor best explained our executive function data in a sample of 202 community dwelling older adults, and was selected as the base measurement model for further analyses. Global grey matter was related to the executive function and speed variables in all four lobar models, but independent contributions of the frontal lobes were not significant. In contrast, when assessing the effect of white matter microstructure, cingulum FA made significant independent contributions to all three executive function and speed variables and corpus callosum FA was independently related to shifting/inhibition and speed. Findings from the current study indicate that while prefrontal grey matter volumes are significantly associated with cognitive neuroscience measures of shifting/inhibition and working memory in healthy

    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, 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. PMID:27616998

    The roles and responsibilities of nurses are expanding, as they become more involved in administration and leadership within their field. Nurses are taking on executive positions, which have become a crucial part of hospital organizations. With this expansion, an executive development program is necessary to provide nurses with the knowledge and competencies that these executive positions require. Their focus must evolve from singular bedside practice to the greater scope of health care administration. Leadership skills are extremely important, in addition to interpersonal, management, mentoring, and interprofessional skills. A number of nursing associations have worked to develop a set of curricula for nurse executive education, but a consistent and specific set of academic requirements has yet to be agreed upon. With the importance of the chief nursing officer's (CNO) role in the function of a hospital and the requirement of the knowledge of the changing health care system in the United States, it is essential that nurses are provided with proper education and training that will help them become successful nurse executives. Some suggestions include a dual MSN/MBA degree, a PhD in nursing, continuing education institutes, and mentoring programs. However, research must be done to clarify the best way to prepare CNOs for their roles. PMID:21900820

    Full Text Available Abstract Background The underlying nature of negative symptoms in psychosis is poorly understood. Investigation of the relationship between the different negative subsymptoms and neurocognition is one approach to understand more of the underlying nature. Apathy, one of the subsymptoms, is also a common symptom in other brain disorders. Its association with neurocognition, in particular executive functioning, is well documented in other brain disorders, but only studied in one former study of chronic patients with schizophrenia. This study investigates the association between apathy and neurocognitive functioning in patients with first episode psychosis (FEP, with the hypothesis that apathy is more associated with tests representing executive function than tests representing other neurocognitive domains. Methods Seventy-one FEP patients were assessed with an extensive neuropsychological test battery. Level of apathy was assessed with the abridged Apathy Evaluation Scale (AES-C-Apathy. Results AES-C-Apathy was only significantly associated with tests from the executive domain [Semantic fluency (r = .37, p Conclusion We replicated in FEP patients the relationship between apathy and executive functioning reported in another study for chronic patients with schizophrenia. We also found apathy in FEP to have the same relationship to executive functioning, as assessed with the Verbal fluency tests, as that reported in patients with other brain disorders, pointing to a common underlying nature of this symptom across disorders.

  2. Executive control training from middle childhood to adolescence.

    2014-01-01

    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.

    The specific aspects of cognition contributing to balance and gait have not been clarified in people with Parkinson's disease (PD). Twenty PD participants and twenty age- and gender-matched healthy controls were assessed on cognition and clinical mobility tests. General cognition was assessed with the Mini Mental State Exam and Addenbrooke's Cognitive Exam. Executive function was evaluated using the Trail Making Tests (TMT-A and TMT-B) and a computerized cognitive battery which included a series of choice reaction time (CRT) tests. Clinical gait and balance measures included the Tinetti, Timed Up & Go, Berg Balance, and Functional Reach tests. PD participants performed significantly worse than the controls on the tests of cognitive and executive function, balance, and gait. PD participants took longer on Trail Making Tests, CRT-Location, and CRT-Colour (inhibition response). Furthermore, executive function, particularly longer times on CRT-Distracter and greater errors on the TMT-B, was associated with worse balance and gait performance in the PD group. Measures of general cognition were not associated with balance and gait measures in either group. For PD participants, attention and executive function were impaired. Components of executive function, particularly those involving inhibition response and distracters, were associated with poorer balance and gait performance in PD. PMID:25136474

  4. Cerebellar damage impairs executive control and monitoring of movement generation.

    Directory of Open Access Journals (Sweden)

    Emiliano Brunamonti

    Full Text Available Executive control of motor responses is a psychological construct of the executive system. Several studies have demonstrated the involvement of the cerebral cortex, basal ganglia, and thalamus in the inhibition of actions and monitoring of performance. The involvement of the cerebellum in cognitive function and its functional interaction with basal ganglia have recently been reported. Based on these findings, we examined the hypothesis of cerebellar involvement in executive control by administering a countermanding task in patients with focal cerebellar damage. The countermanding task requires one to make a movement in response to a 'go' signal and to halt it when a 'stop' signal is presented. The duration of the go process (reaction time; RT, the duration of the stop process (stop signal reaction time; SSRT, and their relationship, expressed by a psychometric function, are recorded as measures of executive control. All patients had longer go process duration in general and in particular, as a proactive control, as demonstrated by the increase in RT after erroneously performed stop trials. Further, they were defective in the slope of the psychometric function indicating a difficulty on triggering the stop process, although the SSRT did not differ from controls. Notably, their performance was worse when lesions affected deep cerebellar nuclei. Our results support the hypothesis that the cerebellum regulates the executive control of voluntary actions. We speculate that its activity is attributed to specific cerebellar influence over the cortico-striatal loop.

    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.

    During the past decade, economic and political forces have caused radical transformations in health care systems resulting in changed circumstances within which nursing executives must function. This paper provides an understanding of nursing executives' roles and responsibilities and the impact changes in the health industry have had on their careers. One hundred and forty-seven (52%) of the 281 nursing executives employed in the Queensland Public Health Sector completed a postal self-administered survey. The findings of this study demonstrate their role has expanded to include not only nursing administration, but also responsibility for financial, human resources, strategic and resource management, staff development and quality improvement. The impact of these role changes has affected the health and well-being of nursing executives, with nearly half reporting increased stress, frustration and irritation. Their workload has increased and some reported deterioration in their health, specifically, exhaustion, fatigue and insomnia. Respondents reported they now have less time to spend with families and friends, which has had a negative impact on family relationships. Overall, nursing executives were satisfied with their current position, the work itself and their relationships with their co-workers, but dissatisfied with organisational aspects, especially the quality of mentorship and opportunities for promotion.

    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.

    Improvements and advances in the development of computer architecture now provide innovative technology for the recasting of traditional sequential solutions into high-performance, low-cost, parallel system to increase system performance. Research conducted in development of specialized computer architecture for the algorithmic execution of an avionics system, guidance and control problem in real time is described. A comprehensive treatment of both the hardware and software structures of a customized computer which performs real-time computation of guidance commands with updated estimates of target motion and time-to-go is presented. An optimal, real-time allocation algorithm was developed which maps the algorithmic tasks onto the processing elements. This allocation is based on the critical path analysis. The final stage is the design and development of the hardware structures suitable for the efficient execution of the allocated task graph. The processing element is designed for rapid execution of the allocated tasks. Fault tolerance is a key feature of the overall architecture. Parallel numerical integration techniques, tasks definitions, and allocation algorithms are discussed. The parallel implementation is analytically verified and the experimental results are presented. The design of the data-driven computer architecture, customized for the execution of the particular algorithm, is discussed.

    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.

    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.

    1990-01-01

    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.

    2015-12-01

    The effects of two types of rumination on different kinds of executive functions were investigated. Fifty-nine participants (M age = 22.8 yr., SD = 2.5) were assigned to one of three conditions and instructed either to: (1) ruminate in a self-distanced way, (2) ruminate in a self-immersed way, or (3) think about the layout of their campus following anger induction. Afterward, the participants were directed to finish tasks designed to assess three kinds of executive functions: shifting, inhibition, and updating. Results showed that self-immersed rumination impaired shifting ability the most, while participants engaged in self-distanced rumination showed the worst performance on the inhibition task. No significant difference was found in the updating task. These results suggest that rumination influenced particular executive functions in different ways. PMID:26595287

  19. Researching in Execution Modes for Concurrent Active Rules

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    It is known as Coupling Modes that how the rule in active database system is triggered to execute by rule monitor when some special events occurs. In general, the Coupling Modes may be divided into immediate, deferred and detached modes in active database systems. This paper classifies the coupling modes into syn-coupling and asyn-coupling modes, according to the key issue, synchrony/asynchrony, in parallel programming language. Rule execution semantics for various coupling modes is distinctly defined. It is beneficial to implementation and usage of the active rule system. After graph-based rule system (E-RG) and its execution model, which have been researched in their previous works, are chiefly described, the authors show the various strategies to construct the syn-coupling and asyn-coupling modes in E-RG rule system, based on semantics for coupling modes.

    Full Text Available Implementation of local budget revenues is a very important sub-phase of the local budgetary process its correct accomplishment ensures regularity and efficiency in revenue collection, which will cover the local budget expenditures. Through this scientific approach we intended to achieve an analysis of the implementation of revenues mobilized to the local budgets in Romania. The study started with fixing the concept of execution of budget revenues and defining its phases, and followed with the analysis of the implementation of local budget revenues in three levels, namely: the overall local budgets in Romania, at the city level and at the community level. We have to mention that the analysis of the execution of local budgets was done in 2011, based on existing data in the last occurrence of the Romanian Statistical Yearbook for 2012. The paper concluded with some considerations regarding the execution of local budgets revenues and some proposals for improving the collection of local income.

    2005-03-01

    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.

    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

    Researchers and developers of NextGen systems can use predictive human performance modeling tools as an initial approach to obtain skilled user performance times analytically, before system testing with users. This paper describes the CogTool models for a two pilot crew executing two different types of a datalink clearance acceptance tasks, and on two different simulation platforms. The CogTool time estimates for accepting and executing Required Time of Arrival and Interval Management clearances were compared to empirical data observed in video tapes and registered in simulation files. Results indicate no statistically significant difference between empirical data and the CogTool predictions. A population comparison test found no significant differences between the CogTool estimates and the empirical execution times for any of the four test conditions. We discuss modeling caveats and considerations for applying CogTool to crew performance modeling in advanced cockpit environments.

    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 Mild cognitive impairment (MCI may take several forms, and amnestic MCI (aMCI has been recognized as an early stage of Alzheimer’s Disease (AD. Impairment in executive functions including attention (eMCI may be indicative of several neurodegenerative conditions. Executive impairment is frequently found in aMCI, it is significant for prognosis, and patients with eMCI may go on to develop AD. Recent studies have found changes in white matter integrity in patients with eMCI to be more sensitive than measures of cortical atrophy. Studies of genetic high-risk groups using sensitive cognitive neuroscience paradigms indicate that changes in executive function may be a cognitive marker useful for tracking development in an AD pathophysiological process.

    2014-01-01

    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.

    This commentary on urban transportation and land use explores the complex relations among activity, movement, and land use. It identifies techniques for coordinated land and transportation development that support goals of increasing transportation efficiency, reducing need for motor-vehicle travel, improving quality of urban life, and maintaining vitality of cities. It addresses such diverse topics as urban form, carpooling, travel disincentives and restraints, walking, zoning, travel behavior, citizen participation, access design, noise, development management, and many others. Confirmed by the analysis were two underlying premises: transportation and land use are quite interrelated physical elements of very complex urban systems with myriad impacts on social, economic, environmental, resource, and other elements; and urban government will continue to be largely responsible for physical development within cities and will be increasingly held accountable for its actions and decisions by a well-informed public. Information is presented for use by local policymakers, citizens, and professionals. Federal and state roles are supportive in nature, providing financial assistance and using their larger resources to develop, assimilate, and disseminate quality information so essential for local decisions. Implementation of current knowledge would make our cities more hospitable, efficient, and stimulating places in which to live, work, socialize, and play.

    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.

    Executive dysfunction occurs in sickle cell anemia, but there are few early data. Infants with sickle cell anemia (n = 14) and controls (n = 14) performed the “A-not-B” and Object Retrieval search tasks, measuring precursors of executive function at 9 and 12 months. Significant group differences were not found. However, for the A-not-B task, 7 of 11 sickle cell anemia infants scored in the lower 2 performance categories at 9 months, but only 1 at 12 months (P = .024); controls obtained scores...

  1. Management decisions for cogeneration: executive summary

    Energy Technology Data Exchange (ETDEWEB)

    Radcliffe, R.R.; Tabors, R.D.

    1982-07-01

    This report summarizes two interdependent studies which explore the underlying factors in the decision by private, private non-profit, and public sector facility owners to invest in cogeneration technology. They employ factor analysis techniques to explain the decision to invest and discriminant analysis to group the survey respondents into non-cogenerators and potential cogenerators. Data for both studies come from a survey of commercial, industrial, and institutional electric energy consumers who used more than 750 kW demand in any one month of 1981 for a selected electric utility in the Boston area. There were 129 usable responses to the survey of 32.2% of the population. The studies reported here confirm that a number of factors other than purely economic considerations may prevent use of cogeneration technology at the present time. These factors include: uncertainty caused by regulatory action; desire for energy self sufficiency by the organization; financial flexibility; experience with electricity cogeneration or self generation; and capital budget planning methods. These studies provide a ranking of the factors involved in the cogeneration decision explaining most variance to least variance. However, the ranking of factors provides no measure of the importance of these factors in the decision to adopt or not adopt cogeneration technology. The results of these studies can be used to provide a rough estimate of capacity (kW) and energy (kWh) available from potential cogenerators in this electric utility service territory and the probability that a facility can be a cogenerator. These studies project a maximum potential of 106 MW and 559,000 MWH of cogenerated electrical energy in the utility service territory between 1982 and 2002.

  2. Program slicing techniques and its applications

    CERN Document Server

    Sasirekha, N; Hemalatha, Dr M

    2011-01-01

    Program understanding is an important aspect in Software Maintenance and Reengineering. Understanding the program is related to execution behaviour and relationship of variable involved in the program. The task of finding all statements in a program that directly or indirectly influence the value for an occurrence of a variable gives the set of statements that can affect the value of a variable at some point in a program is called a program slice. Program slicing is a technique for extracting parts of computer programs by tracing the programs' control and data flow related to some data item. This technique is applicable in various areas such as debugging, program comprehension and understanding, program integration, cohesion measurement, re-engineering, maintenance, testing where it is useful to be able to focus on relevant parts of large programs. This paper focuses on the various slicing techniques (not limited to) like static slicing, quasi static slicing, dynamic slicing and conditional slicing. This pape...

  3. ENHANCEMENT TECHNIQUES FOR DATA WAREHOUSE STAGING AREA

    Full Text Available Poor performance can turn a successful data warehousing project into a failure. Consequently, several attempts have been made by various researchers to deal with the problem of scheduling the ExtractTransform-Load (ETL process. In this paper we therefore present several approaches in the context of enhancing the data warehousing Extract, Transform and loading stages. We focus on enhancing the performance of extract and transform phases by proposing two algorithms that reduce the time needed in each phase through employing the hidden semantic information in the data. Using the semantic information, a large volume of useless data can be pruned in early design stage. We also focus on the problem of scheduling the execution of the ETL activities, with the goal of minimizing ETL execution time. We explore and invest in this area by choosing three scheduling techniques for ETL. Finally, we experimentally show their behavior in terms of execution time in the sales domain to understand the impact of implementing any of them and choosing the one leading to maximum performance enhancement.

  5. The Dog that Stopped Barking: Mass Legal Executions in 21st Century America

    Directory of Open Access Journals (Sweden)

    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.

    Neural network models that guide neuropsychological assessment practices are increasingly used to explicate depression, though a paucity of work has focused on regulatory systems that are under development in adolescence. The purpose of this study was to evaluate subsystems of attention related to executive functioning including alerting, orienting, and executive attention networks, as well as sustained attention with varying working memory load, in a sample of depressed and well adolescents. Neuropsychological functioning in 99 adolescents diagnosed with major depressive disorder (MDD) and 63 adolescent healthy controls (M = 16.6 years old) was assessed on the Attention Network Test (ANT) and the Continuous Performance Test, Identical Pairs. Adolescents with MDD, particularly those who were not medicated, were slower to process conflict (slower reaction time on the Executive Attention scale of the ANT) compared to controls, particularly for those who were not undergoing psychopharmacological treatment. Tentative evidence also suggests that within the MDD group, orienting performance was more impaired in those with a history of comorbid substance use disorder, and alerting was more impaired in those with a history of a suicide attempt. Adolescents with depression showed impaired executive attention, although cognitive performance varied across subgroups of patients. These findings highlight the importance of examining neurocognitive correlates associated with features of depression and suggest an avenue for future research to help guide the development of interventions.

  17. Remuneration Committee, Board Independence and Top Executive Compensation

    Directory of Open Access Journals (Sweden)

    Chii-Shyan Kuo

    2014-04-01

    Full Text Available In this study, we examine whether the levels and structures of top executive compensation vary discernibly with different levels of board independence. We also examine how the newly mandated adoption of the remuneration committee (RC in Taiwan affects the board independence-executive pay relation. The mandatory establishment of RC for Taiwanese public firms, starting in 2011, is intended to strengthen the reasonableness and effectiveness of the executive compensation structure; thus, it is timely and of interest for practitioners and regulators to understand whether the establishment of RCs can effectively discipline top executive compensation policies. We first find that CEOs of firms that do not appoint independent directors have greater levels of annual pay than is the case for firms that have appointed independent directors, after controlling for the effect of CEO pay determinants. Second, we find that CEO pay for early RC adopters is more closely related to firm performance. Third, we find that the establishing of RCs may decrease CEO pay and enhance the pay-performance association, in particular for firms that have not appointed independent directors; however, this effect is not found to be statistically significant.

  18. 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.
