Hand Action

Transversal hand action in the frontoparallel plane biases the perception of bistable visual motion. This has been called action capture. In daily behaviour, however, hand action in a ‘radial’ direction from the head might be more important, because we frequently reach our hand for an object in front of us while guiding the action with vision. The purpose of this study was to measure the strength of action capture in the radial direction. Horizontal luminance gratings were placed above and below the fixation point. Binocular disparity, perspective contour, and spatial frequency gradient cues were attached to the gratings so that they simulated the ‘ceiling’ and the ‘floor’ of a long corridor. The display was reflected on a tilted mirror to face upward. The subject looked into the display and moved his/her dominant hand toward, or away from, the face behind the mirror. Just after the action onset, detected by the computer, one of the two gratings (the ceiling or the floor) flickered in short period to simulate bistable visual motion in depth (approaching or departing). The subject indicated the perceived motion direction in the frontoparallel plane using a 2AFC (upward or downward) method. The results showed that perceived motion was significantly biased to the ‘departing’ direction when the hand moved ‘away from’ the face, and it was biased to the ‘approaching’ direction when the hand moved ‘toward’ it. It is concluded that action capture occurs not only in transversal but also in radial movements.

The paper presents a microstructure analysis of the crash of the Russian ruble in mid-December 2014. The author shows that the market break probably happened due to the execution of a large order that converted Russian rubles into U.S. dollars over a short period of a few days. Expirations of futures and options as well as possible front-running could have exacerbated the collapse of the Russian currency. The paper discusses measures taken by the Moscow Exchange and Bank of Russia during the episode and makes several recommendations to prevent a repetition of the similar events and provide an effective response in the face of future market breaks.

First Philosophy

The general objective of this study is to analyze the postulate of the ethics of otherness as the first philosophy, presented by Emmanuel Levinas. It is a proposal that runs through Levinas' thinking from his theoretical foundations, to his philosophical criticism. Levinas' thought presents itself as a new thought, as a critique of ontology and transcendental philosophy. For him, the concern with knowledge and with being made the other to be forgotten, placing the other in totality. Levinas proposes the ethics of otherness as sensitivity to the other. The subject says here I am, making myself responsible for the other in an infinite way, in a transcendence without return to myself, becoming hostage to the other, as an irrefutable responsibility. The idea of the infinite, present in the face of the other, points to a responsibility whoever more assumes himself, the more one is responsible, until the substitution by other.

The Subject

AbstractIdentity as traditionally conceived in mainstream Western thought is focused on theory, representation, knowledge, subjectivity and is centrally important in the works of Emmanuel Levinas. His critique of Western culture and corresponding notion of identity at its foundations typically raises the question of the other. Alterity in Levinas indicates existence of something on its own account, in itself independently of the subject’s will or consciousness. The objectivity of alterity tells of the impossible evasion of signs from their destiny, which is the other. The implications involved in reading the signs of the other have contributed to reorienting semiotics in the direction of semioethics. In Levinas, the I-other relation is not reducible to abstract cognitive terms, to intellectual synthesis, to the subject-object relation, but rather tells of involvement among singularities whose distinctive feature is alterity, absolute alterity. Humanism of the other is a pivotal concept in Levinas overturning the sense of Western reason. It asserts human duties over human rights. Humanism of alterity privileges encounter with the other, responsibility for the other, over tendencies of the centripetal and egocentric orders that instead exclude the other. Responsibility allows for neither rest nor peace. The “properly human” is given in the capacity for absolute otherness, unlimited responsibility, dialogical intercorporeity among differences non-indifferent to each other, it tells of the condition of vulnerability before the other, exposition to the other. The State and its laws limit responsibility for the other. Levinas signals an essential contradiction between the primordial ethical orientation and the legal order. Justice involves comparing incomparables, comparison among singularities outside identity. Consequently, justice places limitations on responsibility, on unlimited responsibility which at the same time it presupposes as its very condition of possibility. The present essay is structured around the following themes: (1) Premiss; (2) Justice, uniqueness, and love; (3) Sign and language; (4) Dialogue and alterity; (5) Semiotic materiality; (6) Globalization and the trap of identity; (7) Human rights and rights of the other: for a new humanism; (8) Ethics; (9) The World; (10) Outside the subject; (11) Responsibility and Substitution; (12) The face; (13) Fear of the other; (14) Alterity and justice; (15) Justice and proximity; (16) Literary writing; (17) Unjust justice; (18) Caring for the other.

Gaze Cues

AbstractEye movements toward sequentially presented face images with or without gaze cues were recorded to investigate whether those with ASD, in comparison to their typically developing (TD) peers, could prospectively perform the task according to gaze cues. Line-drawn face images were sequentially presented for one second each on a laptop PC display, and the face images shifted from side-to-side and up-and-down. In the gaze cue condition, the gaze of the face image was directed to the position where the next face would be presented. Although the participants with ASD looked less at the eye area of the face image than their TD peers, they could perform comparable smooth gaze shift to the gaze cue of the face image in the gaze cue condition. This appropriate gaze shift in the ASD group was more evident in the second half of trials in than in the first half, as revealed by the mean proportion of fixation time in the eye area to valid gaze data in the early phase (during face image presentation) and the time to first fixation on the eye area. These results suggest that individuals with ASD may benefit from the short-period trial experiment by enhancing the usage of gaze cue.

abstract This report consists of a summary of the studies conducted on the subject of short-period (6.0-0.3 sec period) noise over a period of approximately three years. Information from deep-hole and surface arrays was used in an attempt to determine the types of waves of which the noise is composed. The theoretical behavior of higher-mode Rayleigh waves and of body waves as measured by surface and deep-hole arrays is described. Both surface and body waves are shown to exist in the noise. Surface waves generally predominate at the longer periods (of the period range discussed) while body waves appear at the shorter periods at quiet sites. Not all the data could be interpreted to define the wave types present.

The Difference

The error in estimating the orientation of a dot pattern was measured as the difference between the orientation of the least-squared-distances line (LS-line) of the pattern and the orientation of a line adjusted by the subject to match the perceived orientation of the pattern. Analysis of the mean errors (averaged over ten subjects) obtained for one hundred patterns confirmed that the orientation of the LS-line represents the orientation of elongated dot-patterns. It is shown that estimated orientation was systematically biased towards the nearest 45° oblique meridian. This bias points to the importance of the ±45° directions as natural norms for left- and right-side tilt in the frontoparallel plane.

This paper aims to investigate the Validity of Altman z-score model to predict financial failure in insurance companies listed on Amman Stock Exchange (ASE) over the period 2011-2016. To achieve the goal of the study, the study depended on the different statistics analytical method and Multiple Linear Regression through doing the statistical analysis of the independent variables on the dependent variable related to the subject of the study through the (E-views) program in order to cover the analytical part of the study, in addition to the descriptive method through relying on books, periodicals, previous studies and financial reports of the insurance companies of the study’ sample, whether the direct or the indirect ones, to cover the theoretical part. The result of the study finds a high predictive power for Z-score model. Moreover, the findings reveal that Z-Score model could be valuable instrumental indicators for many users of financial statement such as financial managers, auditors, lenders, investors, to make right decisions in the face of financial failure.

Nicolae Ceauşescu’s Diplomacy in the Face of Political Changes in Poland in 1989 In 1989, Romania belonged to the communist countries, which particularly strongly attacked communist Poland for carrying out democratic reforms. For many months the diplomacy of communist leader Nicolae Ceaşescu tried to organize a conference of socialist countries on the subject of Poland, but as a result of Moscow’s opposition it did not come to fruition. During the Gorbachev era, the Soviet Union rejected the Brezhnev doctrine, while Romania actually urged its restoration. This was in contradiction with the current political line of Ceauşescu in favor of not interfering in the internal affairs of socialist countries. However, in 1989 it was a threat to communism, which is why historians also have polemics about Romanian suggestions for the armed intervention of the Warsaw Pact in Poland. In turn, Romania did not allow Poland to interfere in the problems of the Polish minority in Bukovina.

Long Term Trend

Financial data volumes are increasing, and this appears to be a long-term trend, implying that data managementdevelopment will be crucial over the next few decades. Because financial data is sometimes real-time data, itis constantly generated, resulting in a massive amount of financial data produced in a short period of time.The volume, diversity, and velocity of Big Financial Data are highlighting the significant limitations oftraditional Data Warehouses (DWs). Their rigid relational model, high scalability costs, and sometimesinefficient performance pave the way for new methods and technologies. The majority of the technologiesused in background processing and storage research were previously the subject of research in their earlystages. The Apache Foundation and Google are the two most important initiatives. For dealing with largefinancial data, three techniques outperform relational databases and traditional ETL processing: NoSQL andNewSQL storage, and MapReduce processing.
