Processing Cycle

Many econophysics applications have modeled financial systems as if they were pure physical systems devoid of human limitations and errors. On the other hand, traditional financial theory has ignored limits that physics would impose on human interactions, communications, and computational abilities. The entropic yield curve blends the physical and human financial worlds in a new, powerful, and surprisingly simple way. This article uses this information theoretic perspective to provide a new explanation of the dynamics and timing of financial cycles. Additionally, the entropic yield curve offers a new method of forecasting market peaks and troughs.

A key to understanding visual cognition is to determine where, when and how brain responses reflect the processing of the specific visual features that modulate categorization behavior - the what. The N170 is the earliest Event-Related Potential (ERP) that preferentially responds to faces. Here, we demonstrate that a paradigmatic shift is necessary to interpret the N170 as the product of an information processing network that dynamically codes and transfers face features across hemispheres, rather than as a local stimulus-driven event. Reverse-correlation methods coupled with information-theoretic analyses revealed that visibility of the eyes influences face detection behavior. The N170 initially reflects coding of the behaviorally relevant eye contra-lateral to the sensor, followed by a causal communication of the other eye from the other hemisphere. These findings demonstrate that the deceptively simple N170 ERP hides a complex network information processing mechanism involving initial coding and subsequent cross-hemispheric transfer of visual features.

This study examines whether personally performing other audit tasks can bias supervising seniors' going-concern judgments. During an audit, the senior performs some audit tasks him/herself and delegates other tasks to staff members. When personally performing an audit task, the senior would focus on the evidence related to that task. We predict that such evidence will have greater influence on the senior's subsequent going-concern judgment. The results of our experiment are consistent with our predictions. When provided with an identical set of information, seniors who performed another audit task for which the underlying facts of the case reflected positively (negatively) on the company's viability, subsequently made going-concern judgments that were relatively more positive (negative). Our results also demonstrate that the well-documented tendency of auditors to attend more to negative information does not always dominate auditors' information processing. Subjects who performed the task for which the underlying facts reflected positively on the company's viability directed their attention to such positive information and, consequently, both their memory and judgments were more positive than those of subjects in the other conditions. Recent findings indicating that biases in seniors' going-concern judgments may not be fully offset in the review process are discussed along with other potential implications of our results.

In this chapter I provide additional rationalization for using the info-metrics framework. This time the justifications are in terms of the statistical, mathematical, and information-theoretic properties of the formalism. Specifically, in this chapter I discuss optimality, statistical and computational efficiency, sufficiency, the concentration theorem, the conditional limit theorem, and the concept of information compression. These properties, together with the other properties and measures developed in earlier chapters, provide logical, mathematical, and statistical justifications for employing the info-metrics framework.

Anomaly detection in complex networks is an important and challenging task in many application domains. Examples include analysis and sensemaking in human interactions, e.g., in (social) interaction networks, as well as the analysis of the behavior of complex technical and cyber-physical systems such as suspicious transactions/behavior in financial or routing networks; here, behavior and/or interactions typically also occur on different levels and layers. In this paper, we focus on detecting anomalies in such complex networks. In particular, we focus on multi-layer complex networks, where we consider the problem of finding sets of anomalous nodes for group anomaly detection. Our presented method is based on centrality-based many-objective optimization on multi-layer networks. Starting from the Pareto Front obtained via many-objective optimization, we rank anomaly candidates using the centrality information on all layers. This ranking is formalized via a scoring function, which estimates relative deviations of the node centralities, considering the density of the network and its respective layers. In a human-centered approach, anomalous sets of nodes can then be identified. A key feature of this approach is its interpretability and explainability, since we can directly assess anomalous nodes in the context of the network topology. We evaluate the proposed method using different datasets, including both synthetic as well as real-world network data. Our results demonstrate the efficacy of the presented approach.

Credit Contracts

The difference in the countries to which both the seller and the buyer belong in the commercial exchanges has increased the discrepancy in the laws and rules that govern the conduct of the most important banking count approved for the settlement of such exchanges, which is the documentary credit process, as a result of the different economic, banking and financial systems from the other, so there was a need to unify These customs and customs are in a unified form, which is called today the unified rules and customs of documentary credit, which are applied to the conduct of documentary credit contracts at the global level. Therefore, we consider it necessary to make an amendment in the Iraqi law regarding the organization of the documentary credit process, because the articles related to the provisions of documentary credits are not sufficient in themselves to indicate all the problems that may result from it due to developments in international trade.

Visual evoked potentials were recorded for 6 adult male subjects in response to single vowels and consonants in printed and script forms. Analysis showed the vowels in the printed form to have evoked responses with shorter latency (component P1 at about 133 msec.) and larger amplitude (component P1-N1) than the other letter-typeface combinations. No hemispheric asymmetries were found. The results partially agree with the behavioral data on the visual information-processing of letters.

Human interactions are being communicated by means of electronic, Internet-based Medias. This research is about representation differ in presentation on online dating applications. This study is aimed at understanding how images are used as a means of creating an identity, specifically through Tinder. Self-presentation is divided into two parts: the front region and the back region. The front region is the area where a person displays a self-presentation that he/she wants to show the audience or user in this context in the picture. Front region consists of setting, appearance, and manner that are related to each other. In the back region, the appearance is a visual appearance that is not displayed or any activity performed. That will create impression management in Tinder which create personal branding. In this study qualitative method are used to answer the research questions. The process of research involves emerging questions and procedures, data typically collected in the participant’s setting, data analysis inductively building from particulars to general themes, and the researcher making interpretations of the meaning of the data. The results showed that starting from self-presentation, every participant have their own style to build their own personal branding to make him/her unique among all the other tinder user. This allows them to stand out. The implication of this research is the need for management of personal branding for every individual involved because personal branding is really important as a form of self-presentation in order to compete in relationship or business.

For over a century anthropologists and folklorists have sporadically recorded a belief that one should not point at a rainbow, lest the offending finger become permanently bent, rot, be supernaturally severed, fall off, etc. In each case the belief was reported for a particular geographical region without apparent awareness of its presence elsewhere, and in no case was an explanation for this curious idea proposed. This paper documents what is called the “Rainbow Taboo” as a global phenomenon, found among peoples of quite varied cultural backgrounds, and it argues that the universality of the belief is a product of the interaction of two independent cognitive elements: an apparently innate sense that the rainbow is associated with the “other world,” and, secondly, a similar sense that pointing with the index finger is aggressive, and should not be used either in normal human interactions or more particularly against the supernatural.
