Your love lifts me higher! The energizing quality of secure relationships

Three studies tested and confirmed the hypothesis that secure attachment relationships lead to feelings of security and energy, as well as willingness to explore. In Study 1, priming a secure attachment relationship increased felt security and energy. In Studies 2 and 3, felt energy mediated the effect of (primed) secure attachment relationships on willingness to explore. In Study 3, the effect of (primed) secure attachment relationships on felt energy and willingness to explore was independent of general positive affect. Secure attachments energize partners, thus enabling exploration.     

Illusory smoke and dazzling fog

It is well known that a flat ellipse rotating in the frontoparallel plane appears, after brief inspection, as a rigid circular disc tilting back and forth in a 3-D space. We here report that rotation of a grey-shaded ellipse on a white or on a black background produces the compelling illusion of a dark smoke or a dazzling fog (depending on the conditions of the background) moving in front of a completely white or completely black tilting disc. The fog effect disappears when there is a luminance contrast all along the perimeter of the ellipse. An experiment is reported showing that the effect can be experienced in static conditions only to a limited extent and mostly in the `dazzling' version, and that relative movement between the contours of the figure and the shaded area is crucial to the occurrence of the effect, while the occurrence of a depth effect is not.

Color appearance of surfaces viewed through fog

How do the colors of surfaces seen through fog depend on the chromatic properties of the fog? Prior work (e.g. Chen and D'Zmura, 1998 Perception 27 595-608) shows that the colors of surfaces seen through a transparent filter can be described by a convergence model. The convergence model takes into account color shift and change in contrast. Whether the convergence model can also be applied to fog was tested experimentally with an asymmetric matching task. In computer graphic simulation, observers adjusted the color of a surface seen through fog in order to match the color of a surface seen in the absence of fog. The convergence model fits the data well. The results suggest that the color constancy revealed in this task with fog is described best by a model that takes into account both shift in color and change in contrast.     

Performance oriented task-resource mapping and scheduling in fog computing environment

Resource allocation and task scheduling is a complex task in fog computing environment because of the inherent heterogeneity among the fog devices. The proposed work attempts to solve the problem by using the popular multi criteria decision making methods such as AHP and TOPSIS. The goal of this paper is to propose a model for performance oriented task - resource mapping in a fog computing environment. MIPS, RAM & storage, uplink latency, downlink latency, uplink bandwidth, downlink bandwidth, trust, cost per MIPS, cost per memory, cost per storage and cost per bandwidth are the various performance characteristics considered in this work for task – resource mapping. Two different multi-criteria decision making methods are employed in order to assess the performance characteristics of the fog devices. In the first method, Analytic Hierarchy Process (AHP) is used for both priority weight calculation and ranking of fog devices. In the second method, AHP is used for priority weight calculation, based on the weights yielded by AHP, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) algorithm is executed in order to rank the fog devices. Then the fog devices can be allocated to the tasks based on its rank. Furthermore, a motivational example is also demonstrated to validate the proposed method. Simulation results show that the proposed technique exhibits superior performance over other scheduling algorithms in the fog environment by incorporating performance, security, and cost metrics into scheduling decisions.     

A study of the compliance level of connected vehicle warning information in a fog warning system based on a driving simulation

The accidents in the freeway are frequent and more serious on foggy days. Connected vehicle (CV) technology as a new technology can inform drivers of fog conditions in advance so the drivers can adjust their driving behaviors through Human Machine Interface (HMI) and Dynamic Message Sign (DMS) in the fog warning system. The level of driver's compliance with a fog warning system is the key to assessing the effectiveness of the fog warning system. To evaluate the compliance level of fog warning system, the study established a CV system testing platform based on driving simulator, and analyzed the changes in driving behavior and influencing factors for drivers under three different visibility conditions (No fog, light fog and heavy fog) based on the platform, finally, comprehensive evaluation of the optimal fog warning system under different foggy conditions based on the compliance level were made. Research indicators are divided into three aspects: 1) the response degree, including the mean speed, the minimum speed in the fog zone, the difference of the speeds when entering and leaving the fog zone, the proportion of speed following, and the speed reduction proportion prompt; 2) the response start time, which is the time to start slowing down to the speed limit; and 3) the response time duration, namely, the time in which the speed limit is followed. The results show that the response degree of the driver to the fog warning system is high, the fog warning system can effectively reduce the driving speed of the drivers and improve the speed following proportion of the drivers, the deceleration ratio of the driver at each warning point is relatively high, and the influencing factors of various indicators are complex but are mostly related to visibility and technical level. Comprehensive evaluation results show that the warning mode of the combined HMI and DMS has the highest level of compliance under light fog conditions, and when fog concentration increases, compliance level of fog warning system with HMI only is higher than others. The study establishes a reference platform for CV system and provides methods and index system for the compliance level of CV research.     

The Red and The Real

It is often claimed that principles of individuation imply essential properties of the things individuated. For example, sets are individuated by their members, hence sets have their members essentially. But how does this inference work? First I discuss the form of such inferences, and conclude that the essentialist inference is not a purely formal matter: although there is a form which all principles of individuation have in common, it is not true that any statement of that form is a principle of individuation, and hence there is no valid inference based purely on that form. However, I argue that there is a viable version of the essentialist inference nonetheless. The resources for a proper reconstruction of this type of inference can be gathered from reflections upon the role principles of individuation play in the project of the ontologist: such principles turn out to carry a modal weight similar to that of definitions or conceptual truths. It follows that, no matter how austere the ontology, some portion of essentialist modality is inevitable.     

The Return Of The Religious

Recents discussions of expansion in the European Union and the possibility of envisioning a Muslim country in it has exacerbated the deep-seated anxiety about Islam among the liberal and extreme right in Europe. This paper suggests that there are recurring elements in the discourse of European cultural identity and one of these elements is the representation of Islam in its alterity to European identity and civilization. Questioning the thesis of a radical break with the Christian past, this paper questions whether the European cultural identity which is being formed today signifies a break with a religious form of identification. The liberal and extreme right opposes Turkish membership on the grounds that the differences between ‘European values’ and ‘European culture and lifestyle’ and Turkey's culture are what makes the latter essentially and fundamentally external to the essence of Europe. Tracing the remnants of Christian discourse in the contemporary fashioning of European identity, this paper discusses how Christianity, with its secularized versions, which are now displaced to culture and lifestyle, still holds a privileged position as a unifying theme in Europe. It suggests that one of the tests that awaits Europe is whether it will be capable of articulating a new but democratic identity for Europe, one that is responsive to the differences of the other or whether it wants to continue to be European by way of its old methods of exclusion.

The Units Of Selection And The Causal Structure Of The World

Genic selectionism holds that all selection can be understood as operating on particular genes. Critics (and conventional biological wisdom) insist that this misrepresents the actual causal structure of selective phenomena at higher levels of biological organization, but cannot convincingly defend this intuition. I argue that the real failing of genic selectionism is pragmatic – it prevents us from adopting the most efficient corpus of causal laws for predicting and intervening in the course of affairs – and I offer a Pragmatic account of causation itself which ultimately bears out the claim that genic selectionism misrepresents the causal structure of selective contexts.     

The Activities of The Scandinavian Societies

Freud's concept of the death instinct has given rise to many different interpretations which have often been contradictory. It is in fact already possible to discern two diametrically opposite meanings of this concept in Freud's work from 1920—Beyond the Pleasure Principle—in which he first introduced the concept of the death instinct. In this paper, it is argued that both these meanings are relevant in describing psychical life, although only one of these meanings actually qualifies for the concept “death instinct”. Beyond the Pleasure Principle was written in order to try to understand some everyday, as well as clinical phenomena which could not be explained by the so-called pleasure principle. Freud postulated something beyond the pleasure principle, which initially seemed to have to do with binding energy. I will preserve this idea and attempt to develop it within the context of a phenomenological analysis of time. The temporalization of the subject involves a very basic affirmation of existence, in that the subject experiences something constant, something that can be said to possess the quality of a gestalt. I propose that that which is beyond the pleasure principle—this binding of energy—should be understood as the opposite of the idea of a primordial death instinct striving towards death. In this case, that which is beyond the pleasure principle reflects an original affirmation of existence, which could be said to correspond to Freud's first meaning of the death instinct. The second meaning—for which the name “death instinct” seems to be applicable—concerns the discharge of energy, which from a temporal point of view shows itself as a tendency to dissolution. The concept of the death instinct in its various meanings is discussed in connection with phenomenological reflections on time, which is a different approach from Freud's attempt to ground the death instinct in biology.     

The neglected bulimic: The nonpurger

For nearly 10 years bulimia has been recognized officially as a distinct eating disorder, and yet in that time only minimal attention has focused on the nonpurging subtype. The present investigation compared 21 DSM-III-R diagnosed nonpurging bulimics with 22 non-eating-disordered controls on three standardized questionnaires and during a unique assessment task. In this procedure subjects imagined that they were the character in a series of slides and audiotaped flooding scenes. The content of the stimuli ranged from food and weight cues to issues hypothesized to play a role in the development or maintenance of bulimia (e.g., rejection or loss of control fears). A MANOVA conducted on the three questionnaires was highly significant, with the Beck Depression Inventory and the Restraint Scale being responsible for the elevated bulimic scores. A repeated-measures ANOVA performed on the self-report ratings during the exposure task also achieved significance, as the bulimics reported higher anxiety reactions than controls to each experimental stimulus. Significant skin conductance reactions were detected when a group of only the most psychophysiologically responsive bulimics and controls were compared. The importance of continued comprehensive evaluations with DSM-III-R nonpurging bulimics was emphasized.This research was supported by grants both from the University of New Mexico's Research Allocation Committee and the Biomedical Research Support Grant committee. Portions of this paper were presented at the Association for the Advancement of Behavior Therapy annual conference, Boston, November 1987.     

The Logic of The Goldhagen Debate

Since Daniel J. Goldhagen's Hitler's Willing Executioners: Ordinary Germans and the Holocaustattempts to show that the Holocaust is explicable and can be understood largely in terms of a single cause, “eliminationist anti-Semitism”, it is not surprising that the book has generated an international debate. What is surprising is the magnitude and emotional intensity of the debate. This article argues that the deepest flaws in it Hitler's Willing Executioners,as well as the chasm of disagreement between Goldhagen's detractors and defenders, have as much to do with reasoning and concepts as with matters of fact. It concludes that Goldhagen's central argument is stronger than many of his critics claim, but that the inadequacy of his cognitive interpretation of anti-Semitism and his unexamined psychological assumptions weaken his attempt to explain the Holocaust.
