Human connectome studies suggest that the brain has a modular small world network structure with rich-club effect. Such structure emerges spontaneously in simple model neural networks, (e.g. coupled maps), through adaptive rewiring according to the dynamic functional connectivity. The utility of adaptive rewiring has so far exclusively been demonstrated for unweighted networks; it is anything but guaranteed to work as well for weighted networks. We investigate adaptive rewiring in weighted networks, comparing various right-skewed, symmetrical, and left-skewed fixed weight distributions. We examine how network clustering, path length, modularity, and rich club coefficients develop for weakly, intermediate and strongly coupled networks. At low coupling strength, the weight distribution, as well as episodes of functional synchrony, have a significant effect on network evolution. With increased coupling strengths, all weighted networks robustly develop architectures similar to the unweighted ones. Adaptive rewiring appears relatively ineffective in networks with (biologically implausibly) extreme right-skewed weight distributions but performed most economically in biologically plausible log-normal distributions. 相似文献

The development in the interface of smart devices has lead to voice interactive systems. An additional step in this direction is to enable the devices to recognize the speaker. But this is a challenging task because the interaction involves short duration speech utterances. The traditional Gaussian mixture models (GMM) based systems have achieved satisfactory results for speaker recognition only when the speech lengths are sufficiently long. The current state-of-the-art method utilizes i-vector based approach using a GMM based universal background model (GMM-UBM). It prepares an i-vector speaker model from a speaker’s enrollment data and uses it to recognize any new test speech. In this work, we propose a multi-model i-vector system for short speech lengths. We use an open database THUYG-20 for the analysis and development of short speech speaker verification and identification system. By using an optimum set of mel-frequency cepstrum coefficients (MFCC) based features we are able to achieve an equal error rate (EER) of 3.21% as compared to the previous benchmark score of EER 4.01% on the THUYG-20 database. Experiments are conducted for speech lengths as short as 0.25 s and the results are presented. The proposed method shows improvement as compared to the current i-vector based approach for shorter speech lengths. We are able to achieve improvement of around 28% even for 0.25 s speech samples. We also prepared and tested the proposed approach on our own database with 2500 speech recordings in English language consisting of actual short speech commands used in any voice interactive system. 相似文献

This paper describes the new security solutions based on cognitive approaches and new computing paradigm called cognitive cryptography. This new security area establish a new generation of computational methods and security systems, focused on creation intelligent cryptographic algorithms and security protocols using cognitive information processing approaches. Such systems are designed for semantic evaluation of encrypted data, and allow to select the most appropriate techniques of its encryption. This paper presents a possible application of such techniques for different security tasks like authentication, secret sharing, secure data management etc. Additionally, some cryptographic solutions inspired by biological models will be presented. 相似文献

Character virtues are morally based actions that enable and individual and his or her social world to thrive across time and place. The morally valanced relation between individual and context involved in character virtue development may be studied productively by research and program evaluation focused on four facets of virtues: (a) Character virtue development involves mutually beneficial relations between the individual and the context (individual ⇔ context relations); (b) Coherence, reflecting the Aristotelian concept of phronesis, enables understanding of the specific ways in which an individual may contribute positively to the context that, in turn, supports him or her; (c) Specific character virtues develop in specific places at specific times through specific individual ⇔ context relations; and 4. Idiographic analysis is a useful first step in the study of character virtue development. Implications of these ideas for research and the evaluation of character education programs are discussed. 相似文献

The aim of this paper is to examine feeling‐toned complexes from a developmental psychological perspective. From this perspective feeling‐toned complexes emerge when basic needs are not met. A very similar theory is put forward by Jeffery Young in his Schema Therapy (Young, Klosko, & Weishaar 2005). His basic needs concept, developed on the basis of empirical research, covers four basic needs which are: attachment, autonomy, and self‐worth, as well as play and spontaneity. My proposition is to deal with this conceptual view from a Jungian perspective insofar as we can integrate the four basic needs, however adding a fifth: the basic need for meaning in the theory of feeling‐toned complexes. Emotional schemas and feeling‐toned complexes are then comparable patterns. The strengths and weaknesses of Analytic Psychology compared to Jeffrey Young's schema therapy are further discussed. The foundation of the feeling‐toned complexes on unmet basic needs lends itself to including a further reference, namely Jaak Panksepp’s neuroscientific findings. Panksepp formulates seven basic affective systems which I discuss first, then I focus on what could be gained from the basic needs concept and finally I turn to the feeling‐complex in an attempt to integrate neuroscientific findings into complex theory. 相似文献

The paper reviews the course of the controversy surrounding Jung's theory of archetypes beginning in the mid 1990s and continuing to the present. Much of this controversy was concerned with the debate between the essentialism of the evolutionary position of Anthony Stevens as found in his 1983 book Archetypes: A Natural History of the Self, and the emergence model of the archetypes proposed in various publications by Hogenson, Knox and Merchant, among others. The paper then moves on to a consideration of more recent developments in theory, particularly as derived from an examination of the philosopher Gilles Deleuze, who introduces Bergson's somnambulistic unconscious into the discussion of Jung's theories. It is suggested that this largely unexamined influence on Jung may provide answers to some of the unanswered questions surrounding his theorizing. The paper concludes by suggesting that the notion of the somnambulistic unconscious may resemble Atmanspacher's argument for a dual‐aspect monism interpretation of Jung. 相似文献

Supporting decision-making processes when the elements of a group are geographically dispersed and on a tight schedule is a complex task. Aiming to support decision-makers anytime and anywhere, Web-based group decision support systems have been studied. However, the limitations in the decision-makers’ interactions associated to this scenario bring new challenges. In this work, we propose a set of behavioral styles from which decision-makers’ intentions can be modelled into agents. The goal is that, besides having agents represent typical preferences of the decision-makers (towards alternatives and criteria), they can also represent their intentions. To do so, we conducted a survey with 64 participants in order to find homogeneous operating values so as to numerically define the proposed behavioral styles in four dimensions. In addition, we also propose a communication model that simulates the dialogues made by decision-makers in face-to-face meetings. We developed a prototype to simulate decision scenarios and found that agents are capable of acting according to the decision-makers’ intentions and fundamentally benefit from different possible behavioral styles, just as a face-to-face meeting benefits from the heterogeneity of its participants. 相似文献

Crisis incidents are volatile situations that can pose significant risk to those involved and to law enforcement. The idiosyncratic conditions that lead to such incidents, as well as their volatility, often militate against consistent explanatory models. However, the application of overarching paradigms, such as the action systems model, has shown some promise in imposing order in the domain. Recent research has successfully differentiated crisis incidents into the four distinct modes of the action systems model: conservative, adaptive, integrative, and expressive. The purpose of this paper is to attempt to replicate this recent study using 242 cases from the United States, Ireland, Canada, and Sweden. Data analysis involves smallest space analyses and constrained multidimensional scaling. Although the results supported the underlying structure of original proposed behavioural model, there are a few deviances. These differences along with the potential influence of cultural variations, offence variable selection, the type of incident, and the sample under scrutiny are discussed. It is evident that there remain several challenges, and further research is required, prior to developing a unified framework. 相似文献

Phonological development is sometimes seen as a process of learning sounds, or forming phonological categories, and then combining sounds to build words, with the evidence taken largely from studies demonstrating ‘perceptual narrowing’ in infant speech perception over the first year of life. In contrast, studies of early word production have long provided evidence that holistic word learning may precede the formation of phonological categories. In that account, children begin by matching their existing vocal patterns to adult words, with knowledge of the phonological system emerging from the network of related word forms. Here I review evidence from production and then consider how the implicit and explicit learning mechanisms assumed by the complementary memory systems model might be understood as reconciling the two approaches. 相似文献

The period during which grown children leave home and establish a new, self‐supporting family is called emerging adulthood. This paper uses psychoanalytic concepts and family‐life‐cycle theory to analyze the film Rebel without a Cause ( 1955 ) as a dramatic example of three families going through this phase. Freud's ( 1910 ) rescue‐motif of the child trying to save an endangered peer to repay his parents for having been nurtured is also characteristic of this period and is considered practice for parenting the next generation. Proximate conflict and support enable two of the film's families to continue the path to reproduce themselves. 相似文献
