We propose a new Real-coded GA(RCGA) using the combination of two crossovers, UNDX-m and EDX. The search region of UNDX-m is biased to the inside area that the population of the RCGA covers. Because of this search bias, the GA using UNDX-m causes stagnation of its search if the cost function has a kind of structure, so called, a ridge structure or a multiple-peak structure. In order to overcome this stagnation, we propose a new crossover EDX, whose search is biased (...) toward extrapolative one. Experimental results show that RCGA with EDX can deal with both ridge-structure function whose dimension reaches more than hundreds and multiple-peak function whose optimum resides at the corner of the search area.

This paper presents the Real-coded Genetic Algorithms(RCGA) which can treat with high-dimensional ill-scaled structures, what is called, k -tablet structure. The k -tablet structure is the landscape that the scale of the fitness function is different between the k -dimensional subspace and the orthogonal (n-k) -dimensional subspace. The search speed of traditional RCGAs degrades when high-dimensional k -tablet structures are included in the landscape of fitness function. In this structure, offspring generated by crossovers is likely to spread wider region than (...) the region where the parental population covers. This phenomenon causes the stagnation of the search. To resolve this problem, we propose a new crossover LUNDX- m, which uses only m -dimensional latent variables. The effectiveness of the proposal method is tested with several benchmark functions including k -tablet structures and we show that our proposal method performs better than traditional crossovers especially when the dimensionality n is higher than 100.

This paper presents a kernel density estimation method by means of real-coded crossovers. Functions of real-coded crossover operators are composed of probabilistic density estimation from parental populations and sampling from estimated models. Real-coded Genetic Algorithm (RCGA) does not explicitly estimate probabilistic distributions, however, probabilistic model estimation is implicitly included in algorithms of real-coded crossovers. Based on this understanding, we exploit the implicit estimation of probabilistic distribution of crossovers as a kernel density estimator. We also propose an application of crossover kernels (...) to Expectation-Maximization estimation (EM) of Gaussian mixtures. (shrink)

The paper explores the emergence and development of socially responsible investment (SRI) in Japan. SRI is a recent field in Japan. It is not clear which model it will follow: the European, American or its own model. Through the analysis of the historical roots of SRI, the key actors and motivations that have contributed to its diffusion, the paper provides explorative grounds to sketch the translation mechanisms of SRI in Japan and offers insight into its future path. Based on primary (...) and secondary sources of information, the paper shows that although SRI in Japan holds some similarities with the U.S. and especially with the European model, it remains unique. It highlights the importance of translation and re-interpretation in adopting a practice in a new context. SRI in Japan is still in a dynamic construction process. Although we expect it to develop further, it is difficult to depict its future shape and form. (shrink)

This article examines contemporary representations of sakura (cherry blossom) in cosmetics marketing. Since the Heian period, sakura has been loved and regarded as having tangible and metaphorical significance in Japan. Imagery of sakura is rich in ambiguity and has a complex history as evident in its use in the militaristic promotion of heroism, especially related to the Second World War. However, in recent decades, sakura imagery has proliferated across a range of popular culture both inside and out of Japan. In (...) this article we focus on the circulation and meanings of sakura imagery accessible and appropriated in Australia with specific attention to cosmetics. Sakura offers not only aesthetic pleasure but also potentially some health benefits. Our discussion draws on data from surveys and interviews with participants in Australia about their perspectives of sakura aesthetics related to colour symbolism. This is accompanied by close analysis of colour symbolism in recent perfume, skincare and cosmetic marketing, branding and packaging which use sakura imagery. We argue that, using the complex symbolism associated with the wide colour spectrum, sakura imagery has now been refashioned as a versatile promotional tool in the global market, as exemplified by the brand engagement of sakura-themed cosmetics.

Despite the belief that metaphors are thought to be powerful persuasive devices, little empirical evidence exists to support this claim. A first step in examining the persuasive impact of metaphors is to measure recall and production variables concerning the persuasive message. This study examined recollections regarding the Iran-Contra hearings among honors introductory psychology students. Recall of the hearings appeared heavily influenced by externally imposed (i.e., media, politicians) metaphors. Moreover, metaphors used typically expressed an attitude about the Iran-Contra affair, particularly about (...) Lieutenant Colonel Oliver North's involvement. (shrink)

The atomic structure of a ‡ = 3, [110]/{112} grain boundary in a yttria-stabilized cubic zirconia bicrystal has been investigated by high-resolution transmission electron microscopy . It was found that the grain boundary migrated to form periodic facets, although the bicrystal was initially joined so as to have the symmetric boundary plane of {112}. The faceted boundary planes were indexed as {111}/{115}. The structure of the {111}/{115} grain boundary was composed of an alternate array of two types of structure unit: (...) {112}- and {111}-type structure units. HRTEM observations combined with lattice statics calculations verified that both crystals were relatively shifted by [110] along the rotation axis to form a stable grain-boundary structure. A weak-beam dark-field image revealed that there was a periodic array of dislocations along the grain boundary. The grain-boundary dislocations were considered to be introduced by the slight misorientation from the perfect ‡ = 3 orientation. The fact that the periodicity of the facets corresponded to that of the grain-boundary dislocations must indicate that the introduction of the grain-boundary dislocations is closely related to the periodicity of the facets. An atomic flipping model has been proposed for the facet growth from the initial ‡ = 3, {112} grain boundary. (shrink)

By the mid-19th century, an increasing number of Japan's political leaders and scholars realized that Japan had to adapt and incorporate some elements of Western-style industrialization into their own political and economic order as the necessary means to remain independent of Western imperialism. The Opium War in China, and later the Euro-American bombardments of the domain capitals in Choshu and Satsuma demonstrated that trying to defend the realm with only an increased emphasis on coastal defense would ultimately fail to keep (...) out the barbarians from the West. Sakuma Shozan, a samurai scholar from Matsushiro, proposed a dichotomous philosophy of 'Eastern ethics, Western science' as the means to strengthen Japan both internally and externally, and allow Japan to maintain its independence. In this paper, I argue that Sakuma's dichotomous approach can be interpreted within a Hegelian dialectical paradigm. After the traditional order of Japan (Eastern ethics as Idea/Thesis) came into contact with the industrializing order of the West (Western science as Nature/Anti-Thesis), Sakuma believed a new order would be created in Japan (Synthesis) that combined an increased knowledge on the Eastern ethics of Neo-Confucianism with the 'new' scientific knowledge of the West.

Un bambino di quattro anni nascosto sotto il tavolo in cucina, nell'attesa degli eventi che diventeranno poi la sua vita. È questa la prima immagine che appare a Emanuele Severino quando, errando tra i ricordi, riavvolge i fili della propria esistenza. Errando, appunto, perché il ricordo è di per sé falso e distratto. Tra aneddoti e suggestioni, riaffiorano l'infanzia a Brescia e gli anni della guerra; la scomparsa del fratello Giuseppe, arruolatosi come "volontario" sul fronte francese, e l'incontro con Esterina, (...) "la ragazza più bella di Brescia", che diventerà sua moglie ed è lo sfondo di queste pagine; gli studi universitari a Pavia e l'insegnamento alla Cattolica di Milano, a seguito del "maestro" Gustavo Bontadini; la controversia con la Chiesa, che nel 1970 proclamò l'incompatibilità delle sue posizioni con quelle della dottrina cattolica; il rapporto con i figli; la stesura delle sue opere e le conversazioni filosofiche con gli amici. Emanuele Severino, con uno sguardo delicato e ironico, ripercorre la sua vita, illuminando luoghi, volti ed esperienze, perché "ciò che se ne va scompare per un poco. Ma poi, tutto ciò che è scomparso riappare". (shrink)

Con una belleza literaria incomparable, la Comedìa refleja la cosmovisión católica que vertebra la Cristiandad medieval, que tuvo su máximo exponente filosófico y teológico en santo Tomás. A lo largo de todo el itinerario poético, vemos la impronta del Aquinate presente en el meollo de la narración. Aquí analizaré cómo la cuestión teológica fundamental del gobierno divino del mundo permea la Comedìa, tanto en su estructura formal como en ciertos aspectos concretos del viaje de Dante. A partir de dicha premisa, (...) estudiaré las consecuencias que ello tiene en ese orden jurídico manifestado en la «arquitectura» del infierno, cuyo dintel es elocuente: «Giustizia mosse il mio alto fattore; / fecemi la divina podestate, / la somma sapienza e ‘l primo amore». Finalmente, abordaré la proporcionalidad de las penas que sufren los condenados, como indicador de la medida natural de los castigos dictados por justicia divina. (shrink)

Kant says there is a duty to exit the state of nature, to enter into a civil state. He says this is a duty of right, not a duty of virtue. The article discusses the argument he gives to support this view, as well as the contemporary discussion on the relationship between this duty of right and the categorical imperative. The discussion is full of implications. Particularly significant is the view of the Kantian state emerging from it, which challenges the (...) conventional account: instead of a state designed to protect pre-existing individual property rights, property rights are seen as something resulting from the very constitution of the state.

En este artículo se exponen las conclusiones de un estudio cuyo objetivo principal fue describir y analizar las situaciones de discriminación, violencia y desigualdad contra enfermeros/as gays y lesbianas con pretexto de su orientación sexual y/o expresión de género en organizaciones de salud públicas y privadas de Ciudad Autónoma de Buenos Aires (en adelante, CABA). Aquí se analizan las estrategias y los modos en que gays y lesbianas gestionan la información personal relativa a su orientación sexual en sus intercambios socio-laborales (...) para evitar el estigma.Este escrito se centra en dos categorías principales que ordenaron la investigación: (a) las posibilidades de expresar la propia orientación sexual en los respectivos espacios de trabajo y su vinculación con el estigma real o anticipado en las interacciones con compañeros/as, superiores y pacientes; y (b) el heterosexismo internalizado como una categoría vinculada tanto con el estigma anticipado y experimentado como con los distintos grados de apertura sobre la propia orientación sexual en el trabajo.Para alcanzar el objetivo propuesto, se adoptó un enfoque cualitativo y se analizaron 20 entrevistas a enfermeros y enfermeras gays, lesbianas y heterosexuales, sumado a la indagación de diversas fuentes secundarias, desde los lineamientos de la teoría fundamentada en datos. Como conclusión, se destaca la asociación entre el grado de asunción de la propia identidad sexual, el uso de estrategias de gestión de la información personal y el heterosexismo internalizado, que repercuten en la reproducción de la opresión y el estigma entre gays y lesbianas en comparación con la población heterosexual. Por lo tanto, este trabajo pretende hacer un aporte significativo a las discusiones y los estudios sobre diversidad sexual en los espacios de trabajo de Argentina y la región. (shrink)
