Cien años después : Nietzsche con rostro humano

A cien años de su muerte, el pensamiento y la obra de Nietzsche siguen interpelándonos y estimulándonos. ¿Pero es verdaderamente recuperable Nietzsche para una cultura y una sociedad democráticas? Tras examinar algunos de los aspectos más tópicos de las lecturas antidemocráticas de su obra, y aunque no escape en modo alguno a toda crítica, se contesta afirmativamente a la vista de las nociones de crítica, perspectivismo, vitalismo, etc. Ello permite recuperar un Nietzsche con rostro humano.After one hundred years of his death, the ideas and the work of Nietzsche continue appealing and stimulating us. But is Nietzsche really compatible with a democratic culture and society? Some of the most commune topics of the antidemocratic lectures of his work are examined in this paper in order to offer a positive answer to this question. Of course Nietzsche is not free of criticisms, but taking note of his notions of criticism, perspectivism, vitalism, etc., becomes possible to retrieve a Nietzsche with human face

A Framework for a Robot's Emotion Engine

An Emotions Engine is a modelling and a simplification of the Brain circuitry that generate emotions. It should produce a variety of responses including rapid reaction-like emotions as well as slower moods. We introduce such an engine and then propose a framework for its translated equivalent for a robot. We then define key issues that need addressing and provide guidelines via the framework, for its implementation onto an actual robot’s Emotions Engine

Ultrasonic imaging of textured alumina

Ultrasonic images representing the bulk attenuation and velocity of a set of alumina samples were obtained by a pulse-echo contact scanning technique. The samples were taken from larger bodies that were chemically similar but were processed by extrusion or isostatic processing. The crack growth resistance and fracture toughness of the larger bodies were found to vary with processing method and test orientation. The results presented here demonstrate that differences in texture that contribute to variations in structural performance can be revealed by analytic ultrasonic techniques

Mean-Periodic Functions Associated with the Jacobi-Dunkl Operator on R

2000 Mathematics Subject Classification: 34K99, 44A15, 44A35, 42A75, 42A63Using a convolution structure on the real line associated with the Jacobi-Dunkl differential-difference operator Λα,β given by: Λα,βf(x) = f'(x) + ((2α + 1) coth x + (2β + 1) tanh x) { ( f(x) − f(−x) ) / 2 }, α ≥ β ≥ −1/2 , we define mean-periodic functions associated with Λα,β. We characterize these functions as an expansion series intervening appropriate elementary functions expressed in terms of the derivatives of the eigenfunction of Λα,β. Next, we deal with the Pompeiu type problem and convolution equations for this operator

Branding fashion through gameplay: the branded gaming and the cool dynamics in the fashion markets. A game-theory approach

Purpose The aim of this study was to investigate the role of immersive gaming on brand coolness and brand equity, with particular emphasis on fashion gaming collaborations. We used game theory as a theoretical framework to analyse immersive branding strategies and gain a deeper understanding of fashion consumers’ decision-making process in gaming environments. Gender, as a significant factor affecting gamers, has been studied as a moderator that impacts the overall proposed framework. Design/methodology/approach A quantitative method was used to assess the significance of relationships within the proposed model empirically. The partial least squares structural equation modelling technique was implemented to assess the relationships of the framework with a sample size of 160 active Malaysian gamers. Findings The findings indicate that brand equity is positively associated with perceived brand coolness. Furthermore, of the three core values of online games, perceived enjoyment is most strongly associated with perceived brand coolness, ahead of the values of self-expression and perceived emotional challenge. The results of the multigroup analysis further suggest that in the fashion industry, building brand equity through online games is strongly related to perceived brand coolness among female respondents, the role of perceived brand coolness being weaker among male respondents. Originality/value The study contributes to the existing literature by providing a deeper understanding of the impact of immersive gaming branding practices on the overall equity of the fashion brand. The results provide insight for fashion brand managers into the significant effect on consumer behaviour outcomes of fashion-gaming collaborations.研究目的 本研究擬探討身歷其境的遊戲體驗在品牌酷感和品牌資產上所扮演的角色; 研究特別強調裝扮遊戲的合作。研究人員以博弈論作為研究的理論框架,來分析沉浸品牌策略、和對時裝消費者在遊戲的環境中如何作出決策取得更深入的瞭解。研究人員探討了性別作為影響遊戲參與者的重要因素,這因素被視為為整個被提出的框架帶來調節的影響和作用。 研究設計/方法/理念 研究人員採用定量方法進行研究,目的為於被提出的模型內之各種關聯的意義進行以經驗為依據的評估。研究人員採用了基於偏最小平方法的結構方程模型研究法,來對一個包含160名活躍的馬來西亞遊戲參與者的樣本進行框架的各個聯繫的評估研究。 研究結果 研究結果顯示,品牌資產與品牌酷感成正相關; 而且,在網絡遊戲的三個核心價值中,感知享受與品牌酷感之間的聯繫最為強烈和密切,超過自我表現和感知情感挑戰兩者的價值; 多群組的分析結果更暗示了在時裝產業裡,透過網絡遊戲去建立品牌資產在女性回應者中是與品牌酷感有強烈密切的關係; 而在男性回應者中,品牌酷感所扮演的角色則較弱。 研究的原創性/價值 本研究使我們能更深入認識沉浸遊戲品牌的慣常做法如何影響時裝品牌的整體資產。研究結果為時裝品牌經理提供了啟示,使他們明瞭時裝遊戲的合作會給消費者行為產生重要的影響

A comparative study of high-field diamagnetic fluctuations in deoxygenated YBa2Cu3O(7-x) and polycrystalline (Bi-Pb)2Sr2Ca3O(10)

We studied three single crystals of YBa2Cu3O{7-x} with Tc= 62.5, 52, and 41 K, and a textured specimen of (Bi-Pb)2Sr2Ca2Cu3O10 with Tc=108 K, for H//c axis. The reversible data were interpreted in terms of 2D lowest-Landau-level fluctuation theory. The data were fit well by the 2D LLL expression for magnetization obtained by Tesanovic etal., producing reasonable values of kappa but larger values of dHc2/dT. Universality was studied by obtaining a simultaneous scaling of Y123 data and Bi2223. An expression for the 2D x-axis LLL scaling factor used to obtain the simultaneous scaling was extracted from theory, and compared with the experimental values. The comparison between the values of the x-axis produced a deviation of 40% which suggests that the hypothesis of universality of the 2D-LLL fluctuations is not supported by the studied samples. We finaly observe that Y123 magnetization data for temperatures above $T_c$ obbey a universal scaling obtained for the diamagnetic fluctuation magnetization from a theory considering non-local field effects. The same scaling was not obbeyed by the corresponding magnetization calculated from the two-dimensional lowest-Landau-level theory.Comment: 7 pages 5 figures, accept in Journ. Low Temp. Phy

Current practices of Saudi corporate governance: A case for reform

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.One of the most debated issues is that of corporate governance. The topic has been investigated by scholars from several scientific fields including the legal. Indeed, corporate governance has been examined by a great number of law scholars, with particular regards to the improvement of various aspects. For example, effective corporate governance focuses on protecting and advancing aspects related to shareholders’ rights, the board of directors and corporations’ internal and external audit systems. The main objective of this research is to suggest reformation to the Saudi corporate governance framework in order to achieve satisfactory corporate governance practices. The second purpose of the research is to investigate the current practices involved in Saudi corporate governance arrangements. The final aim is to determine how a Saudi corporate governance framework would most benefit corporate governance from the Islamic perspective. This study intends to provide a regulatory analysis to influence those regulations that should be implemented to adjust corporate governance practices as they affect the Saudi capital market. The researcher found that Saudi corporate governance has been promulgated in accordance with principles of on-going international corporate governance. Alternatively, the Islamic perspective on corporate governance has been debated more recently, as an idea that needs to be progressed in order to provide associated benefits to the corporate governance framework in Saudi Arabia. Therefore, Saudi corporate governance provisions can be seen as based largely on positive man-made laws. The researcher further discovered that Saudi corporate governance as an institutional framework is divided between several institutions, whether internal or external, which might result in some ambiguity when it comes to implementing good corporate governance practices. However, the research results revealed that Saudi corporate governance provisions have to be reformed in accordance with popular worldwide corporate governance principles, namely the UK Corporate Governance Code, the UK Companies Act and the OECD principles of corporate governance produced

Security Tradeoffs in Rate Splitting Multiple Access: Optimal Signal Splitting vs Revealing

This paper considers the secrecy performance of rate splitting (RS) scheme in multi-user multiple-input single-output (MU-MISO) systems. The split of the users' messages into common and private parts can enhance the sum-rate of the communication systems. However, this split of the messages reveals part of the users' messages making them prone to eavesdropping. Thus, to consider the tradeoff between the sum-rate and the secrecy of RS, new analytical expressions for the ergodic sum-rate and ergodic secrecy rate are derived. Then, based on the analytical expressions of the ergodic rates, novel power allocation strategy that maximizes the sum-rate subject to a target secrecy rate is proposed and investigated. Our Monte Carlo simulations show a close match with our theoretical derivations. They also reveal that, by tuning the portion of the split signals, our power allocation approach provides a scalable tradeoff between sum-rate benefits and secrecy
