We describe a software system for the analysis of defined benefit actuarial plans. The system uses a recursive formulation of the actuarial stochastic processes to implement precise and efficient computations of individual and group cash flows.

The aim of this article is to define the actual construction of the Japanese pension system influenced by the economic and social challenges and implemented pension system reforms. In this article, the development of Japanese pension system reforms is analysed, as well as legal, economic, social environment is identified. Until recently, it was a common perception that Japan has managed economic success without worsening the income inequality and pension benefits, but since the economic recession in the (...) 1990, the Japanese pension system faces a new challenge. Moreover, the Japanese population is ageing rapidly (low birth rate, long life expectancy), therefore, ageing influences the entire society and requires more complex and pressing pension system reforms. Analysis of scientific literature, legal acts, documents, historical methods was used. It may be used as methodical literature studying the actual processes in the field of the pension system reforms in Asian countries. (shrink)

Old-age income protection is provided in wealthy democracies by publicly funded defined-benefit pensions. Budgetary challenges have forced policy makers to consider private alternatives to these traditional systems. I consider the shortcomings of private saving arrangements in duplicating the advantages of public pensions. Some shortcomings can be overcome by introducing compulsory elements into private saving plans. Worker contributions into such plans could be mandatory; some or all worker accumulations in the plans could be converted to annuities at retirement; and (...) workers’ investment choices could be narrowly circumscribed. These restrictions do not eliminate the biggest weakness of private saving plans. Fluctuations in asset prices make it hard even for well-informed savers to select an affordable saving rate and an investment strategy that will assure decent income in old age. Public pension systems partly insulate workers against economic and financial market risks by sharing those risks broadly across workers, retirees, and taxpayers in multiple generations. (shrink)

On the basis of PM2.5 data of the national air quality monitoring sites, local population data, and baseline all-cause mortality rate, PM2.5-related health economic benefits of the Air Improvement Action Plan implemented in Wuhan in 2013–2017 were investigated using health-impact and valuation functions. Annual avoided premature deaths driven by the average concentration of PM2.5 decrease were evaluated, and the economic benefits were computed by using the value of statistical life (VSL) method. Results showed that the number of avoided premature deaths (...) in Wuhan are 21,384 (95% confidence interval (CI): 15,004 to 27,255) during 2013–2017, due to the implementation of the Air Improvement Action Plan. According to the VSL method, the obtained economic benefits of Huangpi, Wuchang, Hongshan, Xinzhou, Jiang’an, Hanyang, Jiangxia, Qiaokou, Jianghan, Qingshan, Caidian, Dongxihu, and Hannan District were 8.55, 8.19, 8.04, 7.39, 5.78, 4.84, 4.37, 4.04, 3.90, 3.30, 2.87, 2.42, and 0.66 billion RMB (1 RMB = 0.1417 USD On 14 October 2019), respectively. These economic benefits added up to 64.35 billion RMB (95% CI: 45.15 to 82.02 billion RMB), accounting for 4.80% (95% CI: 3.37% to 6.12%) of the total GDP of Wuhan in 2017. Therefore, in the process of formulating a regional air quality improvement scheme, apart from establishing hierarchical emission-reduction standards and policies, policy makers should give integrated consideration to the relationship between regional economic development, environmental protection and residents’ health benefits. Furthermore, for improving air quality, air quality compensation mechanisms can be established on the basis of the status quo and trends of air quality, population distribution, and economic development factors.

The COVID-19 pandemic spread catastrophically over the world since the spring of 2020. In this paper, a heterogeneous branching process with immigration is established to quantify the human-to-human transmission of COVID-19 in local communities, based on the temporal and structural transmission patterns extracted from public case disclosures by four provincial Health Commissions in China. With proper parameter settings, our branching model matches the actual transmission chains satisfactorily and, therefore, sheds light on the underlying COVID-19 spreading mechanism. Moreover, based (...) on our branching model, the efficacy of home quarantine and social distancing are explored, providing a reference for the effective prevention of COVID-19 worldwide. (shrink)

Widespread concerns about the long-term fiscal gap in Social Security have prompted various proposals for structural reform, with individual accounts as the centerpiece. Carving out individual accounts from the existing system would shift significant risks and responsibilities to individual workers. A parallel development has already occurred in the area of private pensions. Experience with 401 plans indicates that many workers will have difficulty making prudent decisions concerning investment and withdrawal of funds. Moreover, in implementing any system of voluntary individual accounts, (...) it will be important to design default settings that provide appropriate guidance for workers with heterogeneous levels of financial sophistication and risk tolerance. The central goal of Social Security reform should be to close the fiscal gap in a way that preserves rather than undermines the existing system of mandatory defined benefits for all workers.

Discussion about project management, in both the academic literature and industry, is predominantly based on theories of control, many of which have been developed since the 1950s. However, issues arise when these ideas are applied unilaterally to all types of projects and in all contexts. In complex environments, management problems arise from assuming that results, predicted at the start of a project, can be sufficiently described and delivered as planned. Thus, once a project reaches a critical size, a calendar, and (...) a certain level of ambiguity and interconnection, the analysis centered on control does not function adequately. Projects that involve complex situations can be described as adaptive complex systems, consistent in multiple interdependent dynamic components, multiple feedback processes, nonlinear relations, and management of hard data and soft data. In this study, through a complex network, the dynamic structure of a project and its trajectories are simulated using inference processes. Finally, some numerical simulations are described, leading to a decision making tool that identifies critical processes, thereby obtaining better performance outcomes of projects. (shrink)

The prevailing discourse around AI ethics lacks the language and formalism necessary to capture the diverse ethical concerns that emerge when AI systems interact with individuals. Drawing on Sen and Nussbaum's capability approach, we present a framework formalizing a network of ethical concepts and entitlements necessary for AI systems to confer meaningful benefit or assistance to stakeholders. Such systems enhance stakeholders' ability to advance their life plans and well-being while upholding their fundamental rights. We characterize two necessary conditions for (...) morally permissible interactions between AI systems and those impacted by their functioning, and two sufficient conditions for realizing the ideal of meaningful benefit. We then contrast this ideal with several salient failure modes, namely, forms of social interactions that constitute unjustified paternalism, coercion, deception, exploitation and domination. The proliferation of incidents involving AI in high-stakes domains underscores the gravity of these issues and the imperative to take an ethics-led approach to AI systems from their inception.

Although the theory of definability had many important antecedents—such as the descriptive set theory initiated by the French semi-intuitionists in the early 1900s—the main ideas were first laid out in precise mathematical terms by Alfred Tarski beginning in 1929. We review here the basic notions of languages, explicit definability, and grammatical complexity, and emphasize common themes in the theories of definability for four important languages underlying, respectively, descriptive set theory, recursive function theory, classical pure logic, and finite-universe logic. We (...) review the history of previous studies of the similarities and differences in the theories of definability of the first three of these four languages. A seminal role leading toward unification of the theories has been played by the separation principles introduced by Nikolai Luzin in 1927. Emphasizing analogies and driving toward further unification embracing finite-universe logic we concentrate on a simple example—the first and second separation principles for existential-universal first-order sentences . Using this as a test case for the fundamental problem of how to “finitize” arguments in classical pure logic to the finite-universe case, we are led to the analogous negative solution by using the theory of certain special graphs: a graph is - special for any positive integers m , n , p , q iff it is bipartite with m red points and n blue points and for every p -tuple of red points there is a blue point to which they are all connected . As an aside we introduce for further study a natural “Ramseyesque” increasing sequence A of positive integers, where A is the least positive integer n for which an -special graph exists. (shrink)

What can computers do in principle? What are their inherent theoretical limitations? These are questions to which computer scientists must address themselves. The theoretical framework which enables such questions to be answered has been developed over the last fifty years from the idea of a computable function: intuitively a function whose values can be calculated in an effective or automatic way. This book is an introduction to computability theory (or recursion theory as it is traditionally known to mathematicians). Dr Cutland (...) begins with a mathematical characterisation of computable functions using a simple idealised computer (a register machine); after some comparison with other characterisations, he develops the mathematical theory, including a full discussion of non-computability and undecidability, and the theory of recursive and recursively enumerable sets. The later chapters provide an introduction to more advanced topics such as Gildel's incompleteness theorem, degrees of unsolvability, the Recursion theorems and the theory of complexity of computation. Computability is thus a branch of mathematics which is of relevance also to computer scientists and philosophers. Mathematics students with no prior knowledge of the subject and computer science students who wish to supplement their practical expertise with some theoretical background will find this book of use and interest.

The class of all recursive functions fails to possess a natural hierarchical structure, generated predicatively from "within". On the other hand, many (proof-theoretically significant) sub-recursive classes do. This paper attempts to measure the limit of predicative generation in this context, by classifying and characterizing those (predictably terminating) recursive functions which can be successively defined according to an autonomy condition of the form: allow recursions only over well-orderings which have already been "coded" at previous levels. The question (...) is: how can a recursion code a well-ordering? The answer lies in Girard's theory of dilators, but is reworked here in a quite different and simplified framework specific to our purpose. The "accessible" recursive functions thus generated turn out to be those provably recursive in $(\prod_{1}^{1}-CA)_{0}$. (shrink)

The purpose of this paper is to clarify the relationship between various conditions implying essential undecidability: our main result is that there exists a theory T in which all partially recursive functions are representable, yet T does not interpret Robinson’s theory R. To this end, we borrow tools from model theory — specifically, we investigate model-theoretic properties of the model completion of the empty theory in a language with function symbols. We obtain a certain characterization of ∃∀ theories interpretable (...) in existential theories in the process. (shrink)

The aim of the research is to identify the role of policies and procedures for the electronic document management system in the success of the electronic document management system in the Palestinian Pension Agency. In order to achieve the objectives of the study, the researchers used the analytical descriptive method in which the tries to describe the phenomenon studied, analyze its data, the relationship between its components and the opinions that are raised around it, and use the comprehensive inventory (...) method due to the small size of the society. (108) questionnaires were distributed to the community of 65 employees in Gaza Strip and 43 employees in the West Bank. All the responses were retrieved. The research found that there is a clear adoption by the Commission of the policies and procedures put in place to implement the electronic management system of electronic documents. The study showed that there are no statistically significant differences between the responses of the study population regarding the role of policies and procedures for the electronic document management system in the success of the electronic document management system in the Palestinian Pension Agency due to variable (age, nature of job, specialization). And showed that there is a fundamental difference in the opinion of members of the study community on the role of policies and procedures for the electronic document management system in the success of the electronic document management system in the Palestinian Pension Agency attributed to the scientific qualification, and shows the difference in favor of the bachelor's degree. And years of service, and shows the difference in favor of the 11-15 year category. The research led to a number of recommendations, the most important of which is the increase of interest and awareness of the need to implement policies and procedures to ensure the success of the electronic document management system through access to and benefit from the experiences of other institutions and the private sector. And the need to focus on the attention to develop appropriate and clear plans and dissemination on the electronic document management system and specific to specific objectives and the Commission is committed to apply them, the need to pay attention to the development of strategic plans and policies and work mechanisms commensurate with the electronic document management system, and the need to define a policy in advance to form a team of different specialties of the staff of the Authority and cooperation with consultants from outside the body to work on the electronic document system.

The perception/planning–control conception has a direct predecessor in a cognitive/sensorimotor scheme, where the cognitive branch includes Glover's perception and planning functions. The sensorimotor branch corresponds to Glover's control function. The cognitive/sensorimotor scheme, like the perception/planning–control scheme, differentiates between motor planning and direct motor control, which is inaccessible to awareness or to long-term memory.

Entropy is one of the physical bases for the fractal dimension definition, and the generalized fractal dimension was defined by Renyi entropy. Using the fractal dimension, we can describe urban growth and form and characterize spatial complexity. A number of fractal models and measurements have been proposed for urban studies. However, the precondition for fractal dimension application is to find scaling relations in cities. In the absence of the scaling property, we can make use of the entropy function and (...) measurements. This paper is devoted to researching how to describe urban growth by using spatial entropy. By analogy with fractal dimension growth models of cities, a pair of entropy increase models can be derived, and a set of entropy-based measurements can be constructed to describe urban growing process and patterns. First, logistic function and Boltzmann equation are utilized to model the entropy increase curves of urban growth. Second, a series of indexes based on spatial entropy are used to characterize urban form. Furthermore, multifractal dimension spectra are generalized to spatial entropy spectra. Conclusions are drawn as follows. Entropy and fractal dimension have both intersection and different spheres of application to urban research. Thus, for a given spatial measurement scale, fractal dimension can often be replaced by spatial entropy for simplicity. The models and measurements presented in this work are significant for integrating entropy and fractal dimension into the same framework of urban spatial analysis and understanding spatial complexity of cities.

All organizations have gray areas where the border between right and wrong behavior is blurred, but where a major part of organizational decision-making takes place. While gray areas can be sources of problems for organizations, they also have benefits. The author proposes that gray areas are functional in organizations. Gray areas become problematic when the process for dealing with them is flawed, when gatekeeper managers see themselves as more ethical than their peers, and when leaders, by their own inattention, inaction, (...) and poor modeling, minimize the importance of building a moral community by delegating gray area issues to second-tier administrators. Gray areas provide wiggle room in coping with ethical dilemmas in organizations. (shrink)

Psychology has benefited from an enormous wealth of knowledge about processes of cognition in relation to how the brain organizes information. Within the categorization literature, this behavior is often explained through theories of memory construction called exemplar theory and prototype theory which are typically based on similarity or rule functions as explanations of how categories emerge. Although these theories work well at modeling highly controlled stimuli in laboratory settings, they often perform less well outside of these settings, such as explaining (...) the emergence of background knowledge processes. In order to explain background knowledge, we present a non-similarity-based post-Skinnerian theory of human language called Relational Frame Theory which is rooted in a philosophical world view called functional contextualism. This theory offers a very different interpretation of how categories emerge through the functions of behavior and through contextual cues, which may be of some benefit to existing categorization theories. Specifically, RFT may be able to offer a novel explanation of how background knowledge arises, and we provide some mathematical considerations in order to identify a formal model. Finally, we discuss much of this work within the broader context of general semantic knowledge and artificial intelligence research. (shrink)

: The main contribution of this paper to current philosophical and sociological studies on modeling is to analyze modeling as an object-oriented interdisciplinary activity and thus to bring new insights into the wide, heterogeneous discourse on tools, forms and organization of interdisciplinary research. A detailed analysis of interdisciplinarity in the making of models is presented, focusing on long-standing interdisciplinary collaboration between specialists in infectious diseases, mathematicians and computer scientists. The analysis introduces a novel way of studying the elements of the (...) models as carriers of interdisciplinarity. These elements, being functionally interdependent building blocks, evolve during the modeling work and carry the disciplinary tensions in the process. This shows how the long and challenging process of defining and reformulating the object of research is crucial for understanding the dynamics of interdisciplinarity in the making. (shrink)

We investigate how firms adjust corporate pension plans in response to economic policy uncertainty (EPU). Using a sample of US-listed firms, we find that firms increase pension underfunding levels when facing higher EPU. The result is robust to controlling for pension portfolio returns, discount rates, plan sizes, pension liability, numbers of employees, other macroeconomic factors, difference-in-differences and instrumental variable estimation, and additional evidence of pension risk-shifting. Further analysis reveals that financial distress and information asymmetry induced (...) through EPU are the potential channels. The effect is stronger for firms having CEOs being excessively paid, using cash flow as a performance metric in CEO compensation, paying high dividends, and having short-term institutional investors, whereas the presence of unions, positive corporate culture, and social capital alleviate the effect. Notably, managers, not shareholders, appear to be the party reaping the benefits. Our findings suggest that firms may shift risk to employees in response to heightened uncertainty and institutional characteristics play a moderating role in this crucial business ethics issue.

Around the world, agricultural landscapes are increasingly seen as “multi-functional” spaces, expected to deliver food supplies while improving rural livelihoods and protecting and restoring healthy ecosystems. To support this array of functions and benefits, governments and civil society in many regions are now promoting integrated farm- and landscape-scale management strategies, in lieu of fragmented management strategies. While rural producers are fundamental to achieving multi-functional landscapes, they are frequently viewed as targets of, or barriers to, landscape-oriented initiatives, rather than as leading (...) agents of change. In reality, however, rural producers in many areas have embraced elements of multi-functional land management. In this paper, we explore the role and recent evolution of producer movements in influencing multi-functional farm and landscape management. We explore these roles through six case studies, including a land reform movement in Brazil, indigenous territorial development in Bolivia, conservation agriculture associations in Canada, environmental cooperatives in the Netherlands, indigenous and biocultural heritage associations in Peru, and Landcare groups in the Philippines. These experiences suggest that producer movements are playing pivotal roles in supporting landscape multi-functionality, not only through agroecological farming practices but also through off-farm efforts to conserve ecosystems and support multi-stakeholder landscape planning. On the other hand, interests of producer movements are not always fully aligned with multi-functional landscape management approaches. The contribution of producer movements to multi-functional landscapes depends on these movements including farm and landscape stewardship in their values and goals, and having the political support and capacity to engage meaningfully in multi-stakeholder processes.

In this paper, I propose a populational schema of modeling that consists of: a linear AFSV schema, and a higher-level schema employing the genetic algorithm. The basic ideas of the proposed solution are as follows: whole populations of models are considered at subsequent stages of the modeling process, successive populations are subjected to the activity of genetic operators and undergo selection procedures, the basis for selection is the evaluation function of the genetic algorithm. The schema can be applied to automate (...) the modeling of the mind/brain by means of artificial neural networks: the structure of each network is modified by genetic operators, modified networks undergo a learning cycle, and successive populations of networks are verified during the selection procedure. The whole process can be automated only partially, because it is the researcher who defines the evaluation function of the genetic algorithm. (shrink)

Workforce education forms one of the core aspects of organizational learning which aims for performance as well as efficiency. Learning is goal-oriented in business organizations. Organizations' activities are highly-oriented towards customer satisfaction. Organizations learn from practice and delivery of services to meet consumer needs and necessities. Perfection, efficiency and smart practices define today's multinational organizational culture. But how do the multinational organizations achieve such perfections in their business operations? This paper addresses this issue by linking teleological aspects of learning and (...) practice to performance, adoption of routines, and learning-induced adaptation in order to explain how they achieve "perfection" in practice and operations. Further, the paper attempts to study a particular aspect of organizational (teleological perfectionism) process by modeling scenarios which define goal oriented organizational learning and adaptation, and underpins how such teleological processes effectively benefit organizations in the long run. Conclusions drawn up from an example being modeled in this paper suggest that teleology, or teleological dynamics play significant role in shaping today's organizations and help explain some (or high) degree of perfectionism in their operations.

Let F be a signature and R a strictly orthogonal rewrite system on ground terms of F . We give an effective proof of a bounding condition for R , based on a detailed analysis of how terms are transformed during the rewrite process, which allows us to give recursive bounds on the derivation lengths of terms. We give a syntactic characterisation of the Grzegorczyk hierarchy and a rewriting schema for calculating its functions. As a consequence of this, using (...) results of Elias Tahhan–Bittar, it can be shown that, for n⩾3 , the derivation length functions for functions in Grzegorczyk class E n belong to Grzegorczyk class E n+1 . We also give recursive bounds for the derivation lengths of functions defined by parameter recursion. (shrink)

How the formidable diversity of forms emerges from developmental and evolutionary processes is one of the most fascinating questions in biology. The homeodomain‐containing Hox proteins were recognized early on as major actors in diversifying animal body plans. The molecular mechanisms underlying how this transcription factor family controls a large array of context‐ and cell‐specific biological functions is, however, still poorly understood. Clues to functional diversity have emerged from studies exploring how Hox protein activity is controlled through interactions with PBC class (...) proteins, also evolutionary conserved HD‐containing proteins. Recent structural data and molecular dynamic simulations add further mechanistic insights into Hox protein mode of action, suggesting that flexible folding of protein motifs allows for plastic protein interaction. As we discuss in this review, these findings define a novel type of Hox‐PBC interaction, weak and dynamic instead of strong and static, hence providing novel clues to understanding Hox transcriptional specificity and diversity.

General Process Theory (GPT) is a new (non-Whiteheadian) process ontology. According to GPT the domains of scientific inquiry and everyday practice consist of configurations of ‘goings-on’ or ‘dynamics’ that can be technically defined as concrete, dynamic, non-particular individuals called general processes. The paper offers a brief introduction to GPT in order to provide ontological foundations for research programs such as interactivism that centrally rely on the notions of ‘process,’ ‘interaction,’ and ‘emergence.’ I begin with an analysis of our common (...) sense concept of activities, which plays a crucial heuristic role in the development of the notion of a general process. General processes are not individuated in terms of their location but in terms of ‘what they do,’ i.e., in terms of their dynamic relationships in the basic sense of one process being part of another. The formal framework of GPT is thus an extensional mereology, albeit a non-classical theory with a non-transitive part-relation. After a brief sketch of basic notions and strategies of the GPT-framework I show how the latter may be applied to distinguish between causal, mechanistic, functional, self-maintaining, and recursively self-maintaining interactions, all of which involve ‘emergent phenomena’ in various senses of the term.

With the continual development of artificial intelligence and smart computing in recent years, quantitative approaches have become increasingly popular as an efficient modeling tool as they do not necessitate complicated mathematical models. Many nations have taken steps, such as transitioning to online schooling, to decrease the harm caused by coronaviruses. Inspired by the demand for technology in early education, the present research uses a radial basis function neural network modeling technique to predict preschool instructors’ technology usage in classes based on (...) recognized determinant characteristics of technology acceptance. In this regard, this study utilized the RBFNN approach to predict preschool teachers’ technology acceptance behavior, based on the theory of planned behavior, which states that behavioral achievement, in our case the actual technology use in class, depends on motivation, intention and ability, and behavioral control. Thus, this research design is based on an adapted version of the technology acceptance model with eight dimensions: D1. Perceived usefulness, D2. Perceived ease of use, D3. Perceived enjoyment, D4. Intention to use, D5. Actual use, D6. Compatibility, D7. Attitude, and D8. Self-efficacy. According to the TAM, actual usage is significantly predicted by the other seven dimensions used in this research. Instead of using the classical multiple linear regression statistical processing of data, we opted for a NN based on the RBF approach to predict the actual usage behavior. This study included 182 preschool teachers who were randomly chosen from a project-based national preschool teacher training program and who responded to our online questionnaire. After designing the RBF function with the actual usage as an output variable and the other seven dimensions as input variables, in the model summary, we obtained in the training sample a sum of squares error of 37.5 and a percent of incorrect predictions of 43.3%. In the testing sample, we obtained a sum of squares error of 14.88 and a percent of incorrect predictions of 37%. Thus, we can conclude that 63% of the classified data are correctly assigned to the models’ dependent variable, i.e., actual technology use, which is a significant rate of correct predictions in the testing sample. This high significant percentage of correct classification represents an important result, mainly because this is the first study to apply RBFNN’s prediction on psychological data, opening up a new interdisciplinary field of research.

The article is devoted to the formation of linguistic, communicative and cultural competence among students bilinguals in teaching Russian language and speech culture. The authors put forward the thesis that the training of specialists in the conditions of bilingualism re quires not only a higher level of learning a second language, but also a qualitatively different level of comprehension. It is proved that the discipline ‘Russian and the culture of speech‘ assumes formation of communicative and culturological competence of the higher (...) education institutions, which are trained on two-profile offices taking into account a regional component. Relevance of research in this area is increasing each year since the treatment of the person as the center of all systems of cognition highlights in the pedagogical University the formation of the modern language personality, capable of effective professional activity. The functional approach provides detection of features of functioning of language units in different spheres of public work. The communicative principle means that acquisition of Russian as a means of communication happens in the course of speech practice most approached to process of communication in Russian. The detection of similarity and distinctions between languages, interlingual comparison promotes establishment and a lexical interference. The linguistic-cultural principle provides understanding of language as the phenomena of culture and is connected with ability to define national-cultural components of linguistic units - words, phraseological combinations, grammatical categories of the text. Involvement of regional component as a basis in practice of teaching Russian and culture of speech increases efficiency of all process of training of students of national branch. (shrink)

The “active image” refers to the operative nature of images, thus capturing the vast array of “actions” that images perform. This volume features essays that present a new approach to image theory. It explores the many ways images become active in architecture and engineering design processes and how, in the age of computer-based modeling, images play an indispensable role. The contributors examine different types of images, be they pictures, sketches, renderings, maps, plans, and photographs; be they analog or digital, planar (...) or three-dimensional, ephemeral, realistic or imaginary. Their essays investigate how images serve as means of representing, as tools for thinking and reasoning, as ways of imagining the inexistent, as means of communicating and conveying information and how images may also perform functions and have an agency in their own. The essays discuss the role of images from the perspective of philosophy, theory and history of architecture, history of science, media theory, cognitive sciences, design studies, and visual studies, offering a multidisciplinary approach to imagery and showing the various methodologies and interpretations in current research. In addition, they offer valuable insight to better understand how images operate and function in the arts and sciences in general. (shrink)

In the research of motion video, the existing target detection methods are susceptible to changes in the motion video scene and cannot accurately detect the motion state of the target. Moving target detection technology is an important branch of computer vision technology. Its function is to implement real-time monitoring, real-time video capture, and detection of objects in the target area and store information that users are interested in as an important basis for exercise. This article focuses on how to efficiently (...) perform motion detection on real-time video. By introducing the mathematical model of image processing, the traditional motion detection algorithm is improved and the improved motion detection algorithm is implemented in the system. This article combines the advantages of the widely used frame difference method, target detection algorithm, and background difference method and introduces the moving object detection method combining these two algorithms. When using Gaussian mixture model for modeling, improve the parts with differences, and keep the unmatched Gaussian distribution so that the modeling effect is similar to the actual background; the binary image is obtained through the difference between frames and the threshold, and the motion change domain is extracted through mathematical morphological filtering, and finally, the moving target is detected. The experiment proved the following: when there are more motion states, the recall rate is slightly better than that of the VIBE algorithm. It decreased about 0.05 or so, but the relative accuracy rate increased by about 0.12, and the increase ratio is significantly higher than the decrease ratio. Departments need to adopt effective target extraction methods. In order to improve the accuracy of moving target detection, this paper studies the method of background model establishment and target extraction and proposes its own improvement. (shrink)

In sensorimotor integration, representation involves an anticipatory model of the action to be performed. This model integrates efferent signals (motor commands), its reafferent consequences (sensory consequences of an organism’s own motor action), and other afferences (sensory signals) originated by stimuli independent of the action performed. Representation, a form of internal modeling, is invoked to explain the fact that behavior oriented to the achievement of future goals is relatively independent from the immediate environment. Internal modeling explains how a cognitive system achieves (...) its goals despite variations in the environment with insufficient and noisy sensory–perceptual data. In a self that acts intentionally on the environment, knowledge is dependent upon the necessity to guide actions directed toward an aim. The self-inner model, a representation of internal and external environments (including reafferent and afferent messages) and also of the behavior plans and desirable future states (aims) and efferent intentions (motor planning and motor command messages), is intrinsically linked to a thinking capacity, which is supposed to emerge from the binding of multiple influences. Thinking emerges when higher behavior strategies are considered possible and capable of leading to aims or the fulfillment of intentions. In this model, symbolization processes are projective and anticipatory and, in this way, beyond present referents. Symbolization occurs linked to action planning, command, and regulation in mental simulation. Meaning is related to an inner sense of a self that acts over the environment. (shrink)

The paper builds on both a simply typed term system ${\cal PR}^\omega$ and a computation model on Scott domains via so-called parallel typed while programs (PTWP). The former provides a notion of partial primitive recursive functional on Scott domains $D_\rho$ supporting a suitable concept of parallelism. Computability on Scott domains seems to entail that Kleene's schema of higher type simultaneous course-of-values recursion (scvr) is not reducible to partial primitive recursion. So extensions ${\cal PR}^{\omega e}$ and PTWP $^e$ are studied (...) that are closed under scvr. The twist are certain type 1 Gödel recursors ${\cal R}_k$ for simultaneous partial primitive recursion. Formally, ${\cal R}_k\vec{g}\vec{H}xi$ denotes a function $f_i \in D_{\iota\to\iota}$ , however, ${\cal R}_k$ is modelled such that $f_i$ is finite, or in other words, a partial sequence. As for PTWP $^e$ , the concept of type $\iota\to\iota$ writable variables is introduced, providing the possibility of creating and manipulating partial sequences. It is shown that the PTWP $^e$ -computable functionals coincide with those definable in ${\cal PR}^{\omega e}$ plus a constant for sequential minimisation. In particular, the functionals definable in ${\cal PR}^{\omega e}$ denoted ${\cal R}^{\omega e}$ can be characterised by a subclass of PTWP $^e$ -computable functionals denoted ${\rm PPR}^{\omega e}$ . Moreover, hierarchies of strictly increasing classes ${\cal R}^{\omega e}_n$ in the style of Heinermann and complexity classes ${\rm PPR}^{\omega e}_n$ are introduced such that $\forall n\ge 0. {\cal R}^{\omega e}_n ={\rm PPR}^{\omega e}_n$ . These results extend those for ${\cal PR}^\omega$ and PTWP [Nig94]. Finally, scvr is employed to define for each type $\sigma$ the enumeration functional $E^\sigma$ of all finite elements of $D_\sigma$. (shrink)

Research with computer systems and musical grammars into improvisation as found in the tabla drumming system of North India has indicated that certain musical sentences comprise (a) variable prefixes, and (b) fixed suffixes (or cadences) identical with those of their original rhythmic themes. It was assumed that the cadence functioned as a kind of target in linear musical space, and yet experiments showed that defining what exactly constituted the cadence was problematic. This paper addresses the problem of the status of (...) cadential patterns, and demonstrates the need for a better understanding and formalization of ambiguity in musico-cognitive processing. It would appear from the discussion that the cadence is not a discrete unit in itself, but just part of an ever-present underlying framework comprising the entire original rhythmic theme. Improvisations (variations), it is suggested, merely break away from and rejoin this framework at important structural points. This endorses the theory of simultaneity. However, the general cognitive implications are still unclear, and further research is required to explore musical ambiguity and the interaction of musical, linguistic, and spatio-motor grammars.

This paper studies the extent to which probability functions are recursively definable. It proves, in particular, that the (absolute) probability of a statement A is recursively definable from a certain point on, to wit: from the (absolute) probabilities of certain atomic components and conjunctions of atomic components of A on, but to no further extent. And it proves that, generally, the probability of a statement A relative to a statement B is recursively definable from a certain point on, to wit: (...) from the probabilities relative to that very B of certain atomic components and conjunctions of atomic components of A, but again to no further extent. These and other results are extended to the less studied case where A and B are compounded from atomic statements by means of `` ∀ '' as well as `` ∼ '' and "&". The absolute probability functions considered are those of Kolmogorov and Carnap, and the relative ones are those of Kolmogorov, Carnap, Renyi, and Popper. (shrink)

Because of the mechanism complexity, coupling, and time-space characteristic of alkali-surfactant-polymer flooding, common methods are very hard to be implemented directly. In this paper, an iterative dynamic programming based on a biorthogonal spatial-temporal Wiener modeling method is developed to solve the enhanced oil recovery for ASP flooding. At first, a comprehensive mechanism model for the enhanced oil recovery of ASP flooding is introduced. Then the biorthogonal spatial-temporal Wiener model is presented to build the relation between inputs and states, in which (...) the Wiener model is expanded on a set of spatial basis functions and temporal basis functions. After inferring the necessary condition of solutions, these basis functions are determined by the snapshot method. Furthermore, a theorem is proved to identify parameters in the Wiener model. Combined with the least square estimation, all unknown parameters are determined. In addition, the ARMA model is applied to build the model between states and outputs, whose parameters are identified by recursive least squares. Thus, the whole modeling process for ASP flooding is finished. At last, the IDP algorithm is applied to solve the enhanced oil recovery problem for ASP flooding based on the identification model to obtain the optimal injection strategy. Simulations on the ASP flooding with four injection wells and nine production wells show the accuracy and effectiveness of the proposed method. (shrink)

A new proof is given of the celebrated theorem of M. Davis, H. Putnam and J. Robinson concerning exponential Diophantine representation of recursively enumerable predicates. The proof goes by induction on the defining scheme of a partial recursive function.

The paper builds on a simply typed term system ${\cal PR}^\omega $ providing a notion of partial primitive recursive functional on arbitrary Scott domains $D_\sigma$ that includes a suitable concept of parallelism. Computability on the partial continuous functionals seems to entail that Kleene's schema of higher type simultaneous course-of-values recursion (SCVR) is not reducible to partial primitive recursion. So an extension ${\cal PR}^{\omega e}$ is studied that is closed under SCVR and yet stays within the realm of subrecursiveness. The (...) twist are certain type 1 Gödel recursors ${\cal R}_k$ for simultaneous partial primitive recursion. Formally, the value ${\cal R}_k\vec{g}\vec{H} x i$ is a function $f_i$ of type $\iota \to \iota$ , however, ${\cal R}_k$ is modelled such that $f_i$ is a finite element of $D_{\iota\to\iota}$ or in other words, a partial sequence. It is shown that the Ackermann function is not definable in ${\cal PR}^{\omega e}$. (shrink)

In order to introduce the text description of this class will show seven keywords, they represent In order to understand the general process for the seven. Need to mention is that the author published in Chinese script - title "Gadamer's philosophy of the seven key" - and this content is not the same. In fact, only one in that the use of key words in this speech mentioned the four key words will be used the next article. 1 Linguistics as (...) high as the United States in the "real management and methods," a book in the last third of the contents of the specified language is "the universal medium of interpretation of experience." It is in this medium, things are understood, understanding and interpretation to occur. It is the fundamental and the first thing on a switch, it makes things possible, without it, understanding must not occur. It is in this medium, the real management there, although in terms of the real incidence of management and is not limited to this medium. Sprachlichkeit is up to the universal language of the United States to name the first of of a proper noun. history of as language, history is a popular media, and history is also rising to become "a hermeneutical principle." To understand history, which must be traced back to Heidegger, "and there is time," the first six parts, entitled "Timing and historical nature." This title has been out of correct revelation, history is the study of this structure there is some a result of this there is the same as in the past and the present one there, it was possible there through his plans and will itself which extend to the future. Dilthey on Heidegger benefit of this term and its historical significance, but that裡Dilthey, the basic processes of life, and in Heidegger, the basic process is still alive there in the past and future Among the visual field. It is a learning process rather than the life there is a process, there is a process rather than the life philosophy of life regardless of the process. Dilthey and Gadamer and Heidegger places of historical analysis for the premise. 3 by the historical role of awareness up to the United States, this keyword has not appeared in from Schleiermacher, Dilthey, or Heidegger that裡. But Heidegger once spoke to the author, the concept represented by the word directly from Dilthey and future. Indeed, the word and the "fusion of" two persons都benefit from Hegel and Dilthey, Heidegger than In order to impact. At the same time, for the resumption of encounter with the text of the history of this effort directly, the recall In order to Heidegger and Qike fruit. Up to the United States shows that it is essential that "the existence of the structure." That is to say, it is usually associated with the text coming from a tradition, crushed In order to present before the sight. 4 hermeneutics into the cycle and see in understanding the structure and the first cycle between hermeneutics, there is a close link. Hermeneutics and the cycle regardless of such a concept, not only from a part of the overall future understanding, understanding from the part of the overall future. This is a logical contradiction, but it depicts In order to understand the kind of work does not have the way to recovery. This is to see What are the relationship? Up with the United States use this word in the former understanding of the meaning of a person he can understand any part of the text and context before, must have a pre-understanding. When Schleiermacher hermeneutics for the cycle to take a more formalistic point of view, he also participate in an objective and subjective look for. In order to reject the United States is up for the subjective, and he describes, in understanding the text, our understanding of a person but a different meaning, and this sense of ownership in a situation with a theme of the event . Heidegger the hermeneutic circle and put the world on their own understanding of the context in which the world is time and the existence of the world, in order to In order to reinvent the meaning of hermeneutic circle. It exists in the time being and is expected to forward to the future, it is a person exists in the world of all possibilities of a personal meaning. Gadamer Heidegger and then one more step beyond, he is defined as the cycle of hermeneutics and the interpretation of the traditional sports were a correlation between the movement. Heidegger's masterpiece裡tradition and not important, but those for the traditional and the interpretation of the relationship between text, up to the U.S. In order to play an important role in the analysis. Up to the United States, brought into the discussion In order to "complete expectation" that the key concept, it is subject to the historical role of awareness of the operation of the core. In this part of the contents of the directory for the present review is to show to some of the major associated. 5 authority and tradition up to the United States on the authority of the traditional view is that from his understanding and the hermeneutic circle before the concept developed in the future. Enlightenment for the suspect an effort made ​​to switch the authority of the United States to see coming up is one-sided, because the authority is naturally found in the leading field in a PhD, the referee, professors and experts. Recognize these people for a topic you know even in the natural and appropriate. So regardless of up to his brother's wife is not a legitimate authority and legitimate authority, and authority as a concept to see the future is appropriate. Similarly, our traditional understanding among the living, and we should explore a more deeper with our traditional relationship. Traditional German text is Űberlieferung, incurs passed along . Once again, as a fair decision without dialogue and is not legal to see, up to the United States against this anti-traditional views of the Enlightenment. 6 Depending on the domain of integration sight philosophy of integration is another sign up to the United States is not to find elsewhere. Basically, the text of the encounter with a sight In order to involve the integration of text and interpreter of the visual field of sight. And a man's own awareness is a fusion of traditional with the product. "That is convenient to get a sight of their own, but also requires a fusion of traditional with." In order for each dialogue also involves a fusion of sight. It is a wildcard description of the terminology. 7 Dialogue dialogue leading up to the U.S. interpretation of the theme of philosophy, relying on a life of his ideal, he as such a show of openness. Schleiermacher as high as the United States in general, is a talented rapper. However, the need for a fruitful dialogue open to others point of view, and the need to recognize that he or she may be right. In a true dialogue, both sides都want to talk more close to the truth regardless of management topics, which are more important than winning. Finally, the dialogue is a basic hermeneutical tool, a means to understand, so we coming close to the theme of the issue, but ready to change our point of view. An introductory section explains that the lecture will present seven key terms, representing seven aspects of the universal process of understanding. It is noted that a published lecture in Chinese by this author under the title "Seven Key Terms in the Philosophy of Hans-Georg Gadamer "is not the same as this, and indeed only one of the terms in that lecture is used in this one, although four of them are used in tomorrow's lecture. An introductory section explains that the lecture will present seven key terms, representing seven aspects of the universal process of understanding. It is noted that a published lecture in Chinese by this author under the title "Seven Key Terms in the Philosophy of Hans-Georg Gadamer" is not the same as this, and indeed only one of the terms in that lecture is used in this one, although four of them are used in tomorrow's lecture. 1. Sprachlichkeit-Linguisticality As Gadamer notes in the final third of Truth and Method, language is the "universal medium of hermeneutical experience." It is the medium in which things are understood, the medium in which understanding and interpretation take place. It is fundamental and prior to everything. It makes things possible, and without it understanding cannot take place at all. It is the medium in which truth happens, although there is more than this to the happening of truth. Sprachlichkeit is the term Gadamer uses to name the "universal priority" of language. 2. Geschichtlichkeit-Historicity Like language, history is a universal medium, and historicity is raised to the status of "a hermeneutical principle. "To understand historicity, one has to go back to the six sections of Heidegger's Being and Time that carry the heading" Temporality and Historicity. "Already this title correctly suggests that historicity is a consequence of the ontological structure of Dasein as a being that lives with a past and a present, and also extends itself into the future through projecting possible being. Heidegger is indebted to Dilthey for the term and sense of historicity, but in Dilthey the basic process is life, whereas in Heidegger, the basic process is being-in-the-world in horizons of past and future. It is an ontological process rather than a life process, a process of being rather than the vitalism of life in life-philosophy. Gadamer presupposes Dilthey's and Heidegger's analysis of Geschichtlichkeit . 3. das wirkungsgeschichtliche Bewusstsein-the Historically Effected Consciousness This is a key term in Gadamer that does not appear in Schleiermacher, Dilthey, or Heidegger. Heidegger once remarked to the author that the idea that this term represents is straight out of Dilthey. Certainly it and the "fusion of horizons" are more indebted to Hegel and Dilthey than to Heidegger. At the same time, the effort to restore the historical immediacy of encounter with a text recalls Heidegger and Kierkegaard. Gadamer argues that the essence of it is " the structure of experience. "That is to say, it shatters the present horizon, usually with a text from tradition. 4. Hermeneutische Zirkel and Vorurteil-Prejudice and the Hermeneutical Circle There is an intimate connection between the fore-structure of understanding and the hermeneutical circle. The hermeneutical circle refers to the idea that one understands the part from the whole, but also the whole from the parts. This is a logical contradiction, but it describes the back and forth way that understanding works. What has this to do with prejudices ? Gadamer uses this word as synonymous with pre-understanding, and one has to have a prior understanding before one can understand any part of a text or situation. While Schleiermacher took a more formalistic view of the hermeneutical circle, he also looked at the objective and subjective sides. Gadamer rejects the subjective side and explains that in understanding a text we are not understanding a person but a meaning that resides in a situation and a subject-matter. Heidegger revolutionized the meaning of the hermeneutical circle by placing it in the context of an understanding of self and world that is temporal and existential. It exists in time and anticipates a future, and it is the personal sense of one's possibilities for being in the world. Gadamer took a step beyond Heidegger by defining the hermeneutical circle as the interplay between the movement of tradition and that of the interpreter. Tradition plays little role in Heidegger's masterwork, but it and the interpreter's relation to the text loom large in Gadamer's analysis. The discussion brings in the key concept in Gadamer of the "anticipation of completion" which is central to the working of historically effected consciousness. A review of the table of contents for the section is presented to show some of the major relationships. 5. Autorität und Tradition-Authority and Tradition Gadamer's views with regard to authority and tradition grow out of his concepts of preunderstanding and the hermeneutical circle. The effort by the Enlightenment to discredit all authority seemed one-sided to Gadamer because authority is naturally accorded to doctors, judges, professors, and other experts in a field. To acknowledge that they know more about a subject than you do is natural and appropriate. So Gadamer speaks of legitimate authority and illegitimate authority, but authority as a concept seems appropriate. Likewise, tradition inhabits our understanding, and we should seek an ever deeper relationship to our tradition. The German word for tradition is Űberlieferung, that which is handed down. Again, Gadamer takes up arms against the Enlightenment prejudice against tradition as illegitimate without dialogue or a fair trial. 6. Horizontverschmelzung-Fusion of Horizons The "fusion of horizons "is another trademark of Gadamerian philosophy. It is not found elsewhere. Basically, the encounter with the text involves a fusion of horizons, that of the text and that of the interpreter. Also one's own consciousness is a product of a fusion of horizons with the tradition. "Even to acquire one's own horizon requires a fusion of horizons with the tradition." Every conversation, too, involves a fusion of horizons. It is an all-purpose term. 7. Conversation Conversation is a leitmotif of Gadamer's hermeneutical philosophy, an ideal he lived by, an openness he exemplified. Schleiermacher was a gifted conversationalist, as was Gadamer. But a fruitful conversation requires openness to the viewpoint of the other person, and the acknowledgement that he or she could be right. In a true conversation both partners want to come closer to the truth about a matter, and that is more important than winning. Ultimately, conversation is a basic hermeneutical tool, a means of reaching understanding, so we approach a subject with questions, but ready to change our point of view. (shrink)

Connected devices, such as smartphones and tablets, are exposed to a large variety of attacks. Their protection is often challenged by their resource constraints in terms of CPU, memory and energy. Security chains, composed of security functions such as firewalls, intrusion detection systems and data leakage prevention mechanisms, offer new perspectives to protect these devices using software-defined networking and network function virtualization. However, the complexity and dynamics of these chains require new automation techniques to orchestrate them. This chapter describes (...) an automated orchestration methodology for security chains in order to secure connected devices and their applications. This methodology exploits process learning to establish behavioral models and infer security constraints represented as logical predicates. It then generates and merges a set of chains of security functions on the basis of these predicates. These chains are finally compiled into low-level configuration rules and deployed into the network, optimizing for the underlying topology. The benefits and limits of such a methodology combining machine learning and verification techniques are evaluated by a set of experimental results. (shrink)

The last Episode wasn’t about logic or formal theories at all: it was about common-or-garden arithmetic and the informal notion of computability. We noted that addition can be defined in terms of repeated applications of the successor function. Multiplication can be defined in terms of repeated applications of addition. The exponential and factorial functions can be defined, in different ways, in terms of repeated applications of multiplication. There’s already a pattern emerging here! The main task in the (...) last Episode was to get clear about this pattern. So first we said more about the idea of defining one function in terms of repeated applications of another function. Tidied up, that becomes the idea of defining a function by primitive recursion (Defn. 27). (shrink)

Cognitive function certainly poses the biggest challenge for computational neuroscience. As we argue, past efforts to build neural models of cognition (the target article included) had too narrow a focus on implementing rule-based language processing. The problem with these models is that they sacrifice the advantages of connectionism rather than building on them. Recent and more promising approaches for modeling cognition build on the mathematical properties of distributed neural representations. These approaches truly exploit the key advantages of connectionism, that is, (...) the high representational power of distributed neural codes and similarity-based pattern recognition. The architectures for cognitive computing that emerge from these approaches are neural associative memories endowed with additional mapping operations to handle invariances and to form reduced representations of combinatorial structures.

The primary purpose of this study is to examine the relationship between the dynamic capabilities embedded in ESG management, which are being pursued by global companies, and corporate performance amid increasing uncertainty. Furthermore, the secondary purpose is to examine the function of environmental uncertainty moderating the DCs-performance relationship. Concerning the analysis tool, this study employs topic modeling with Word2Vec embedding that analyzes unstructured data. This was employed as an alternative method beyond the limitations of the traditional approach, i.e., survey or (...) interview. A DCs dictionary was constructed by redesigning the 12 detailed dimensions of Teece’s DCs into 10 dimensions, and then time series scores of individual global companies were extracted by applying this dictionary to the sustainability reports of 97 companies. Sustainability reports of 153 companies among Fortune Global 500 companies announced in 2020 were originally collected, but in the process of collecting additional financial data about these companies from OSIRIS, a total of only 97 companies was selected in the end due to omission of data. A fixed effect panel analysis was conducted, and the main findings are as follows: First, the DCs embedded in ESG management have a positive or negative direct effect on corporate performance. In particular, a statistically significant relationship was not observed in the innovation oriented capabilities, whereas a statistically significant positive relationship was observed in the customer oriented capabilities. Second, uncertainty moderates the relationship between DCs and corporate performance positively or negatively. Interestingly, the moderating effect of uncertainty only appears in the function of the sensing and reconfiguring capabilities. From this, it can be seen that the function of DCs, which is embedded in the ESG management of global companies, is limited due to the imbalance between the sensing-seizing-reconfiguring capabilities. These findings imply that, despite the positive function of DCs embedded in ESG management, costs and benefits occur at the same time, and DCs can improve performance only if there is an organizational adaptation strategy suitable for uncertainty. Accordingly, business managers need to recognize the importance of pursuing sensing-seizing-reconfiguring capabilities in a balanced way to improve corporate performance through ESG management under uncertainty.

De Neys (2021) argues that the debate between single- and dual-process theorists of thought has become both empirically intractable and scientifically inconsequential. I argue that this is true only under the traditional framing of the debate—when single- and dual-process theories are understood as claims about whether thought processes share the same defining properties (e.g., making mathematical judgments) or have two different defining properties (e.g., making mathematical judgments autonomously versus via access to a central working memory capacity), respectively. But if single- (...) and dual-process theories are understood in cognitive modeling terms as claims about whether thought processes function to implement one or two broad types of algorithms, respectively, then the debate becomes scientifically consequential and, presumably, empirically tractable. So, I argue, the correct response to the current state of the debate is not to abandon it, as De Neys suggests, but to reframe it as a debate about cognitive models. (shrink)

Replacing the value-free ideal (VFI) for science requires attention to the broader understanding of how science in society should function. In public spaces, science needed to project the VFI in norms for science advising, science education, and science communication. This resulted in the independent science advisor model and a focus on science literacy for science education and communication. Attending to these broader implications of the VFI which structure science and society relationships is crucial if we are to properly replace the (...) VFI with a better ideal. (shrink)

Because of its practical advantages, machine learning (ML) is increasingly used for decision-making in numerous sectors. This paper demonstrates that the integral characteristics of ML, such as semi-autonomy, complexity, and non-deterministic modeling have important ethical implications. In particular, these characteristics lead to a lack of insight and lack of comprehensibility, and ultimately to the loss of human control over decision-making. Errors, which are bound to occur in any decision-making process, may lead to great harm and human rights violations. It is (...) important to have a principled way of assigning responsibility for such errors. The integral characteristics of ML, however, pose serious difficulties in defining responsibility and regulating ML decision-making. First, we elaborate on these characteristics and their epistemic and ethical implications. We then analyze possible general strategies for resolving the assignment of moral responsibility and show that, due to the specific way in which ML functions, each potential solution is problematic, whether we assign responsibility to humans, machines, or using hybrid models. Then, we shift focus on an alternative approach that bypasses moral responsibility and attempts to define legal liability independently through solutions such as informed consent and the no-fault compensation system. Both of these solutions prove unsatisfactory because they leave too much room for potential abuses of ML decision-making. We conclude that both ethical and legal solutions are fraught with serious difficulties. These difficulties prompt us to re-weigh the costs and benefits of using ML for high-stake decisions.

We introduce a set of biologically and computationally motivated design choices for modeling the learning of language, or of other types of sequential, hierarchically structured experience and behavior, and describe an implemented system that conforms to these choices and is capable of unsupervised learning from raw natural-language corpora. Given a stream of linguistic input, our model incrementally learns a grammar that captures its statistical patterns, which can then be used to parse or generate new data. The grammar constructed in this (...) manner takes the form of a directed weighted graph, whose nodes are recursively (hierarchically) defined patterns over the elements of the input stream. We evaluated the model in seventeen experiments, grouped into five studies, which examined, respectively, (a) the generative ability of grammar learned from a corpus of natural language, (b) the characteristics of the learned representation, (c) sequence segmentation and chunking, (d) artificial grammar learning, and (e) certain types of structure dependence. The model's performance largely vindicates our design choices, suggesting that progress in modeling language acquisition can be made on a broad front—ranging from issues of generativity to the replication of human experimental findings—by bringing biological and computational considerations, as well as lessons from prior efforts, to bear on the modeling approach.

This study evaluated the effects of an exergame program combined with traditional tennis training on autonomic regulation, tennis technique, gross motor skills, clinical reaction time, and cognitive inhibitory control in children. Sixty-three children were randomized into four groups and compared at baseline, 6-month immediately post intervention and at 1-year follow-up post intervention. At 6-month post intervention the combined exergame and regular training sessions revealed: higher breathing frequency, heart rate and lower skin conductance levels during exergaming; additional benefits in the point (...) of contact and kinetic chain elements of the tennis forehand and backhand technique ; negative impact on the shot preparation and the follow-through elements ; higher ball skills ; higher percentages of clinical reaction time improvement and cognitive inhibitory control improvement in both congruent and incongruent trials. The 1-year follow-up test showed no differences in the tennis technique, clinical reaction time and cognitive inhibitory control improvement between groups with the same number of trainings per week. The findings support exergaming as an additional training tool, aimed to improve important cognitive-motor tennis skills by adding dynamics to the standardized training process. Caution should be placed to planning this training, e.g., in a mesocycle, since exergaming might decrease the improvement of specific tennis technique parts of the trainees.. (shrink)
