Abstract:

There have been many attempts to account theoretically for the effects of anxiety on cognitive performance. This article focuses on two theories based on insights from cognitive psychology. The more recent is the attentional control theory ( Eysenck, Derakshan, Santos, & Calvo, 2007 ), which developed from the earlier processing efficiency theory ( Eysenck & Calvo, 1992 ). Both theories assume there is a fundamental distinction between performance effectiveness (quality of performance) and processing efficiency (the relationship between performance effectiveness and use of processing resources), and that anxiety impairs processing efficiency more than performance effectiveness. Both theories also assume that anxiety impairs the efficiency of the central executive component of the working memory system. In addition, attentional control theory assumes that anxiety impairs the efficiency of two types of attentional control: (1) negative attentional control (involved in inhibiting attention to task-irrelevant stimuli); and (2) positive attentional control (involved in flexibly switching attention between and within tasks to maximize performance). Recent (including unpublished) research relevant to theoretical predictions from attentional control theory is discussed. In addition, future directions for theory and research in the area of anxiety and performance are presented.

Abstract:

We contend that if efficiency and reliability are important factors in neural information processing then distributed, not localist, representations are “evolution's best bet.” We note that distributed codes are the most efficient method for representing information, and that this efficiency minimizes metabolic costs, providing adaptive advantage to an organism.

Abstract:

We hypothesized that patterns of sustained attention performance in bipolar disorder were consistent with processing efficiency theory—a theory of the relationship between central processing capacity and performance. We predicted (1) sustained attention deficits during mania because symptoms interfere with limited-capacity executive control processes resulting in decreased performance effectiveness; and (2) decreased processing efficiency during euthymia, as indicated by speed/accuracy tradeoffs, consistent with a stable phenotypic abnormality. Twenty-five manic bipolar, 23 euthymic bipolar, and 28 healthy comparison participants were compared on a continuous performance task and administered symptom-rating scales. The manic group was significantly impaired on overall perceptual sensitivity and demonstrated a significant linear decrease in performance over time, consistent with impaired sustained attention. The euthymic group evidenced significantly slower overall hit reaction time (RT), but when RT was controlled they performed similarly to the healthy group over time. Two discriminant functions combined to separate the groups on manic symptom severity and on-task effort/strategy use. These findings are consistent with processing efficiency theory. They suggest that euthymic patients sustain attention through effortful control at the expense of processing efficiency, while acute mania reduces the capacity for control and impairs sustained attention. Problems with processing efficiency are viewed as trait characteristics of bipolar disorder that may be overlooked by traditional error-based assessments. (JINS, 2005, 11, 49–57.)

Abstract:

The purpose of this study was to examine the central tenets of the Processing Efficiency Theory (PET) in the context of a dual-task auto racing simulation. Participants were placed into either high or low trait-anxiety groups and required to concurrently undertake a driving task while responding to one of four target LEDs upon presentation of either a valid or an invalid cue located in the central or peripheral visual field. Eye movements and dual-task performance were recorded under baseline and competition conditions. Anxiety was induced by an instructional set delivered prior to the competition condition. Findings indicated that while there was little change in driving performance from baseline to competition, response time was reduced for the low-anxious group but increased for the high-anxious group during the competitive session. Additionally there was an increase in search rate for both groups during the competitive session, indicating a reduction in processing efficiency. Implications of this study include a more comprehensive and mechanistic account of the PET and confirm that increases in cognitive anxiety may result in a reduction of processing efficiency, with little change in performance effectiveness.

Abstract:

Complex event processing (CEP) evaluates queries over streams of event data to detect situations of interest. If the event data are produced by geographically distributed sources, CEP may exploit in-network processing that distributes the evaluation of a query among the nodes of a network. To this end, a query is modularized and individual query operators are assigned to nodes, especially those that act as data sources. Existing solutions for such operator placement, however, are limited in that they assume all query results to be gathered at one designated node, commonly referred to as a sink. Hence, existing techniques postulate a hierarchical structure of the network that generates and processes the event data. This largely neglects the optimisation potential that stems from truly decentralised query evaluation with potentially many sinks. To address this gap, in this paper, we propose Multi-Sink Evaluation (MuSE) graphs as a formal computational model to evaluate common CEP queries in a decentralised manner. We further prove the completeness of query evaluation under this model. Striving for distributed CEP that can scale to large volumes of high-frequency event streams, we show how to reason on the network costs induced by distributed query evaluation and prune inefficient query execution plans. As such, our work lays the foundation for distributed CEP that is both, sound and efficient.

Abstract:

Combat is inherently a demanding situation which may increase stress, heighten arousal, and increase anxiety. The Processing Efficiency Theory (PET) was specifically developed to account for how anxiety influences performance. Therefore, the PET provides a potential theory to explain the positive and negative changes in performance in a combat environment. This study is the first attempt to examine PET in the military domain. Using the Small Arms Simulator Testbed (SAST), we investigated the relationship between processing efficiency and performance, considering mental workload, stress, and anxiety effects. Shooting performance effectiveness measures were target acquisition and friend/foe discrimination. Changes in processing efficiency were manipulated by varying degrees of working memory demand and sustained information transfer. The results indicated that shooting performance and processing efficiency, as well as mental workload demands, decreased as the global demand of both tasks increased. Further analyses for anxiety and stress and future directions are discussed.

Abstract:

Research on effects of acute physical exercise on performance in a concurrent cognitive task has generated equivocal evidence. Processing efficiency theory predicts that concurrent physical exercise can increase resource requirements for sustaining cognitive performance even when the level of performance is unaffected. This hypothesis was tested in a dual-task experiment. Sixty young adults worked on a primary auditory attention task and a secondary interval production task while cycling on a bicycle ergometer. Physical load (cycling) and cognitive load of the primary task were manipulated. Neither physical nor cognitive load affected primary task performance, but both factors interacted on secondary task performance. Sustaining primary task performance under increased physical and/or cognitive load increased resource consumption as indicated by decreased secondary task performance. Results demonstrated that physical exercise effects on cognition might be underestimated when only single task performance is the focus.

Abstract:

Processing efficiency theory predicts that anxiety reduces the processing capacity of working memory and has detrimental effects on performance. When tasks place little demand on working memory, the negative effects of anxiety can be avoided by increasing effort. Although performance efficiency decreases, there is no change in performance effectiveness. When tasks impose a heavy demand on working memory, however, anxiety leads to decrements in efficiency and effectiveness. These presumptions were tested using a modified table tennis task that placed low (LWM) and high (HWM) demands on working memory. Cognitive anxiety was manipulated through a competitive ranking structure and prize money. Participants’ accuracy in hitting concentric circle targets in predetermined sequences was taken as a measure of performance effectiveness, while probe reaction time (PRT), perceived mental effort (RSME), visual search data, and arm kinematics were recorded as measures of efficiency. Anxiety had a negative effect on performance effectiveness in both LWM and HWM tasks. There was an increase in frequency of gaze and in PRT and RSME values in both tasks under high vs. low anxiety conditions, implying decrements in performance efficiency. However, participants spent more time tracking the ball in the HWM task and employed a shorter tau margin when anxious. Although anxiety impaired performance effectiveness and efficiency, decrements in efficiency were more pronounced in the HWM task than in the LWM task, providing support for processing efficiency theory.

The theory of mechanical abstractive design is the newest mechanical design concept at present. Lots of software achieve a certain degree of intelligence with the development of computer technology. And the processing efficiency is improved to a great deal through intelligent processing. Many suggestions for reference can be proposed during the processing. The study is based on the concept and characteristics of mechanical design. And the core theory of mechanical abstractive design, such as intelligence, automatic modeling and relative abstraction, was analyzed combined with the implication of abstractive design. Thus, a certain degree of reference is hopefully provided for the pragmatic design work.

Abstract:

Effects of anxiety on the antisaccade task were assessed. Performance effectiveness on this task (indexed by error rate) reflects a conflict between volitional and reflexive responses resolved by inhibitory processes (Hutton, S. B., & Ettinger, U. (2006). The antisaccade task as a research tool in psychopathology: A critical review. Psychophysiology, 43, 302–313). However, latency of the first correct saccade reflects processing efficiency (relationship between performance effectiveness and use of resources). In two experiments, high-anxious participants had longer correct antisaccade latencies than low-anxious participants and this effect was greater with threatening cues than positive or neutral ones. The high- and low-anxious groups did not differ in terms of error rate in the antisaccade task. No group differences were found in terms of latency or error rate in the prosaccade task. These results indicate that anxiety affects performance efficiency but not performance effectiveness. The findings are interpreted within the context of attentional control theory (Eysenck, M. W., Derakshan, N., Santos, R., & Calvo, M. G. (2007). Anxiety and cognitive performance: Attentional control theory. Emotion, 7 (2), 336–353).

Full text

Abstract:

Active inference is a normative framework for explaining behaviour under the free energy principle—a theory of self-organisation originating in neuroscience. It specifies neuronal dynamics for state-estimation in terms of a descent on (variational) free energy—a measure of the fit between an internal (generative) model and sensory observations. The free energy gradient is a prediction error—plausibly encoded in the average membrane potentials of neuronal populations. Conversely, the expected probability of a state can be expressed in terms of neuronal firing rates. We show that this is consistent with current models of neuronal dynamics and establish face validity by synthesising plausible electrophysiological responses. We then show that these neuronal dynamics approximate natural gradient descent, a well-known optimisation algorithm from information geometry that follows the steepest descent of the objective in information space. We compare the information length of belief updating in both schemes, a measure of the distance travelled in information space that has a direct interpretation in terms of metabolic cost. We show that neural dynamics under active inference are metabolically efficient and suggest that neural representations in biological agents may evolve by approximating steepest descent in information space towards the point of optimal inference.

Abstract:

A change in values of modern society has led to the transformation of economic development models based on the greening of industrial activities. This problem is particularly relevant for industrial regions, including the Urals, where environmental pressure mostly depends on the mining and metallurgical industry, which is a source of industrial waste. In this regard, we develop a methodology for assessing environmental and economic efficiency of technological solutions for processing industrial raw materials. The research methodology is based on the theory of industrial production efficiency, sustainable development theory and circular economy principles. To assess the efficiency, we applied the methods of comparative, structural and logical, economic and statistical analysis, as well as real options method. The comparative analysis revealed various trends in the generation, recycling, and accumulation of waste from mining and smelting activities in the whole Russia and the Middle Urals in the period 2013–2019. The industrial waste of the Urals is unique in terms of its multicomponent composition, including ferrous, non-ferrous and rare-earth metals. Thus, the real options method is optimal for assessing the efficiency of recycling industrial waste. The analysis of the approaches to the assessment of environmental and economic efficiency confirmed that traditional methods based on cost indicators are unreliable compared to the real options method. We described the main stages of this method and developed an algorithm for assessing environmental and economic efficiency of processing industrial raw materials. Further, we identified the real options for processing industrial resources of steel production that influence managerial decisions in a changing environment. Due to the versatility of the developed method, which considers both external uncertainty and requirements of advanced technologies, we recommend using this method for selecting effective investment projects aimed at processing industrial raw materials.

Abstract:

Background: All-optical processing has a huge superiority in speed and efficiency than traditional optical-electrical-optical signal processing. Four-wave-mixing is an important nonlinear parametric process to achieve all-optical processing. Objective: We proposed the photonic crystal waveguide to enhance the conversion efficiency of four-wave-mixing significantly in practical application. Results: We demonstrated a waveguide composed of silicon with mono-layer graphene-coated as core and Si-Ge distributed periodically on both sides as cladding. By the introduction of the slow light effect of Si-Ge photonic crystal and the localization effect of graphene, the conversion efficiency of four-wave-mixing had enhanced dramatically. Results:: The conversion efficiency can be increased by 16dB compared with a silicon waveguide. The maximum efficiency as high as -9.1dB can be achieved in the Si-Ge-Graphene photonic crystal waveguide (SGG-PhCWG). The propagation loss can be decreased to 0.032dB/cm. Conclusion:: Numerical results of the proposed SGG-PhCWG matched well with nonlinear coupled- mode theory. This configuration offered a new physical mechanism and solution for alloptical signal processing and high-efficiency nonlinear nanoscale devices.

The methodology includes the following factors: cost-effectiveness, social significance of disposal, safety of waste processing, resource saving, environmental reputation. The method includes several stages: analysis of the regulatory framework, the settlement and analytical stage, and the final stage - the assessment of economic efficiency. The main difference between the method and the one developed earlier is in an integrated approach to justifying the creation of a modern waste treatment system in commercial enterprises. The offered method develops the theory of economic and investment analysis, as well as the theory of making management decisions in managing the development of commercial enterprises.

Abstract:

Nontransferred direct current (dc) laminar plasma jets of pure argon were generated at atmospheric pressure, with a generator having an interelectrode insert. Associated with the experimental investigation, similarity theory was adopted to examine the arc voltage characteristics, thermal efficiency, and jet length change of the laminar plasma. Jet flow temperature and velocity were evaluated by various methods. The jet shows good stability, reproducibility, and regular flow field change as functions of generating parameters. Applications of laminar plasma jets for ZrO2 ceramics spray coating and remelt strengthening of metal surface were attempted. The results indicated favorite process efficiency and controllability of the laminar plasma heating.

Abstract:

Foraging theory has been the inspiration for several decision-making algorithms for task-processing agents facing random environments. As nature selects for foraging behaviors that maximize lifetime calorie gain or minimize starvation probability, engineering designs are favored that maximize returned value (e.g. profit) or minimize the probability of not reaching performance targets. Prior foraging-inspired designs are direct applications of classical optimal foraging theory (OFT). Here, we describe a generalized optimization framework that encompasses the classical OFT model, a popular competitor, and several new models introduced here that are better suited for some task-processing applications in engineering. These new models merge features of rate maximization, efficiency maximization, and risk-sensitive foraging while not sacrificing the intuitive character of classical OFT. However, the central contributions of this paper are analytical and graphical methods for designing decision-making algorithms guaranteed to be optimal within the framework. Thus, we provide a general modeling framework for solitary agent behavior, several new and classic examples that apply to it, and generic methods for design and analysis of optimal task-processing behaviors that fit within the framework. Our results extend the key mathematical features of optimal foraging theory to a wide range of other optimization objectives in biological, anthropological, and technological contexts.

Abstract:

A new theory of visual search is tested experimentally with simple colour patches. The essential element of this new theory is that, whatever the search materials, efficiency increases continuously with (i) decreasing similarity between targets and nontargets, and (ii) increasing similarity between one nontarget and another. Control of ‘attention’ (access to visual short-term memory) is seen as a competitive interaction between display elements, and the theory shows how stimulus similarities influence the outcome of this competition. One alternative view is that parallel visual processes are limited to local mismatch detection. Search is parallel if the target forms a break in an otherwise homogeneous field, but is serial when absolute stimulus identification is required. It is shown, however, that even colour identification can be parallel, providing targets and nontargets are sufficiently dissimilar. A second alternative view is that search for simple features is parallel whereas search for conjunctions is serial. Conjunction search, however, has a characteristic similarity structure: different kinds of nontarget each share one relevant attribute with the target, but none with one another. When this structure is mimicked in search for colour patches, correspondingly poor performance is obtained.

Abstract:

Since the semiconductor laser has a high conversion efficiency, it has many expectations for effective application. There are increasing application trials of processing at actual factories and jobsites. Moreover, it can currently be used as a heat source to directly conduct processing. This is called direct-diode laser (DDL). However, since there is almost no information regarding the DDL structure and beam mode, there are no scientific documents for the theoretical treatment of this heat source. This is considered to have interfered with the broad application for development. This research establishes the theoretical analysis of the semiconductor heat source for material processing, and we attempted to employ a simulation for processing. To verify the established theory, surface hardening and welding processing were performed as typical processing.

Abstract:

Author compares various models of relation between stress and efficiency of a motor operation, described with the Inverted-U Principle (IUP), Multidimensional Theory of Anxiety (MTA) and Catastrophe Model of Anxiety (CMA). He presents the “classical” theory, invented by R.M. Yerkes and J.D. Dodson in 1908, and modified significantly by D.O. Hebb in 1955. The latter is commonly known as the Inverted-U Principle (IUP). Author focuses his analyses on two factors determining the efficiency of a motor operation: cognitive factor (depth of information processing) and temporal factor (speed of information processing). Stress, of multimodal nature, may either stimulate, or deteriorate the efficiency of a motor operation just being performed. One of the possible descriptions of the structure of a motor operation bases on the theory invented by N.A. Bernstein (Brain Skyscraper – BS). Its continuation enabled creation of two other scientific models, the Modalities’ Ladder (ML) and the Movements’ Management Matrix (MMM). They make a specific perspective enabling joining the theories concerning stress-efficiency relation. This perspective unveils two mechanisms of efficiency deterioration: hypervigilance and hypovigilance, and, consequently, their different products: mistake, proper execution, choking and collapse. Finally, author remarks that the already long known theories may still include great resources of scientific explainability, and that the main task of science is not absolutely true mirroring of reality, but creation of its simplified models. They should be comprehensible enough to be useful in practice. This concerns also the issues of rather complex relation between stress and efficiency in a motor operation.

Abstract:

Modern grammar development platforms often support multiple devices for representing properties of a natural language, giving the grammar writer some freedom in implementing analyses of linguistic phenomena. These design alternatives can have dramatic consequences for efficiency both in processing and in grammar building. In this paper I report on three experiments in making systematic modifications to a broad-coverage grammar of English in order to gain efficiency without loss of linguistic elegance. While the experiments are to some degree both platform-dependant and theory-bound, the kinds of modifications reported should be applicable to any unification-based grammar which makes use of types. The results make a strong case for a more visible role for the linguist in the collaborative effort to achieve greater processing efficiency.

Full text

Abstract:

The effect of different attentional strategies on motor efficiency, measured by reaction-response time components, has historically been based on memory-drum construct theory, which implied limited attention and motor-response processing. The present study contrasts these principles by using a recording system and automatic analysis of reaction-response parameters. A within-subject design allowed detailed observation of the frequency of each preparatory set within each parameter and with control of the effects of practice. Analysis indicates (a) practice changes the effects of the attentional strategies on the components of reaction response but not the actual movement; (b) the motor-set strategy produces shorter movement times and, inversely, higher motor reaction times; and (c) the motor-sensory set integrated strategy produces improvements on each component of the reaction response. These findings suggest the memory-drum construct theory needs revision and should be based on other attentional models.

Abstract:

Technology transfer is a powerful growth factor in industrial value added in the processing industries. Of course, it is important to assess the efficiency of technology transfer in the processing industry by analysing its influencing factors and discussing strategies to improve technological innovation. However, it is still difficult to measure its direct impact on the improvement or creation of value added, and one of the most relevant indicators that could measure the real impact of technology transfer is efficiency. The efficiency of the modes of technology transfer will therefore be the comparative relationship between inputs and outputs in the technology transfer activities based. It is an indicator for measuring the profitability of technology investment in industrial transformation. In our study, we will try to integrate a mathematical tool that allows us to solve optimization problems using a program operating under different constraints imposed by a model. The usefulness of this model depends on the ability to implement it, by the managers of production lines who are called upon to implement R&D, innovation or technology transfer projects. Based on panel data of processing industries that use one or more modes of technology transfer in the Souss-Massa region, this article will examine trends in the efficiency of technology transfer use, mainly as a result of technological progress and the promotion of technology transfer.

Abstract:

Parallel processing as a method to improve computer performance has become a development trend. Based on rough set theory and divide-and-conquer idea of knowledge reduction, this paper proposes a classification method that supports parallel attribute reduction processing, the method makes the relative positive domain which needs to be calculated repeatedly independent, and the independent relative positive domain calculation could be processed in parallel; thus, attribute reduction could be handled in parallel based on this classification method. Finally, the proposed algorithm and the traditional algorithm are analyzed and compared by experiments, and the results show that the proposed method in this paper has more advantages in time efficiency, which proves that the method could improve the processing efficiency of attribute reduction and makes it more suitable for massive data sets.

A new composite vibrating mode is presented in this paper. Modeling and dynamic analysis are studied according to two-degree-of-freedom systems theory. The effects of vibration parameters, including swing angle, swing frequency, vibrating direction angle, and translation frequency, on the screening efficiency were researched by means of experiment research over a new laboratory-scale composite vibrating screen which is designed based on the new composite vibrating mode. The results are analysed in terms of curves and fitting equations. Compared to the translation mode and swing mode, the screening performance of the new composite vibrating mode, both in screening efficiency and in processing capacity, is significantly improved.
