Teoria della conoscenza e neuroscienze
Authors: Lourdes Velàzquez
Published: April 2016

La teoria della conoscenza può essere intesa in due modi diversi, a seconda di che cosa si intende per conoscenza. In un primo senso, per conoscenza si intende il processo mediante cui conosciamo. In un secondo senso la conoscenza è intesa come il risultato di tale processo, ossia come sinonimo di sapere. Questi due significati sono riflessi nei diversi termini con cui vengono denotati in altre lingue. Mentre una teoria della conoscenza intesa come sapere non ha relazioni significative con le neuroscienze (ma piuttosto con discipline filosofiche come la logica, la metodologia, la semiotica, l'ontologia), una teoria dei processi conoscitivi ha rapporti significativi con le neuroscienze, e fin dall'antichità i filosofi hanno riconosciuto nel cervello il supporto fisico delle attività cognitive superiori. Con ciò, tuttavia, le neuroscienze non possono presentarsi come surrogato di una teoria filosofica del conoscere, in quanto i processi cognitivi debbono essere preliminarmente definiti in sede filosofica, al fine di poter studiare le loro correlazioni (bidirezionali) con fenomeni nervosi.
La cosmologia nel pensiero di Evandro Agazzi
Authors: Musso Paolo
Published: April 2016

La riflessione sulla cosmologia è uno degli aspetti meno noti del pensiero di Agazzi. Tuttavia, benché ne abbia scritto solo in poche occasioni e alcune considerazioni siano state superate dai grandi progressi scientifici nel frattempo intercorsi, altre sue intuizioni appaiono tuttora sorprendentemente attuali e feconde, forse ancor di più di quando furono formulate, come cercherò di mostrare in questo articolo. Su questa base tenterò inoltre di proporre una definizione precisa dell'oggetto proprio della cosmologia scientifica e di chiarire i suoi corretti rapporti con la filosofia della natura e la metafisica.

Published: April 2016

This descriptive type of cross-sectional study was conducted to assess the prevalence and determinants of smoking among some selected private university students of Dhaka city in Bangladesh with sample size of 190. The students were aged between 18 and 26 years with mean age as 22.42 ± 1.820. The majority of the respondents (82.1%) were of the nuclear family and 63.2% were living with their friends. Among the smokers (n=187) 50.5% spent Tk. 91-130 and 26.3% spent Tk. 131-170 for smoking daily. The present study also revealed that 98.4% students were smokers of whom 79.7% started smoking at ages between 13 to15 years. Among them 42.5% smoked 12-16 cigarettes, 27.4% smoked 17-21 cigarettes per day and rest 19.4%, 7.0% and 3.8% were taking 22-26 , 2-6 and 7-11 cigarettes per day. Regarding knowledge on hazards associated with smoking 39% mentioned it was loss of money and 35.2% mentioned lung cancer. The study further revealed that 93% smoked due to peer pressure and 91.4% got intervention to quit smoking. Of them 39.8% received counseling from friends as intervention. A significant association was found from this study between number of cigarette taken per day with living partner (p= 0.000). As smoking kills the smokers, awareness program to be lunched in a way so that people voluntary leaves the habit.Update Dent. Coll. j: 2015; 5 (2): 40-46

Authors: Sultana Wahida , Rita Sufia Nasrin , Sadat SM Anwar
Published: April 2016

Sturge Weber Syndrome (SWS) or Encephalotrigeminal Angiomatosis is specifically a rare non hereditary congenital sporadic disorder of elusive etiology. It belongs to a group of disorders collectively known as the phakomatoses (motherspot diseases). It has a vast continuum of cutaneous, neurologic, ophthalmic and oral manifestations. It consists of congenital hamartomatous malformations that may affect the eye, skin, and central nervous system (CNS) at different times, characterized by the combination of venous angiomas of leptomeninges, face, jaws and oral soft tissues. The classic pathognomonic features of disease include angioma of the leptomeninges extending to cerebral cortex with ipsilateral angiomatous lesions, unilateral facial nevus after one division of trigeminal nerve and epileptic convulsions. The most characteristic oral manifestation is represented by gingival hemangiomatous lesion usually restricted to ipsilateral maxilla or mandible. We report a case of Sturge Weber Syndrome with its characteristic oral manifestations and review of relevant prevailing literature.Update Dent. Coll. j: 2015; 5 (2): 47-51
Unit Root Tests: The Role of the Univariate Models Implied by Multivariate Time Series
Authors: Cappuccio Nunzio , Lubian Diego
Published: April 2016

In cointegration analysis, it is customary to test the hypothesis of unit roots separately for each single time series. In this note, we point out that this procedure may imply large size distortion of the unit root tests if the DGP is a VAR. It is well-known that univariate models implied by a VAR data generating process necessarily have a finite order MA component. This feature may explain why an MA component has often been found in univariate ARIMA models for economic time series. Thereby, it has important implications for unit root tests in univariate settings given the well-known size distortion of popular unit root test in the presence of a large negative coefficient in the MA component. In a small simulation experiment, considering several popular unit root tests and the ADF sieve bootstrap unit tests, we find that, besides the well known size distortion effect, there can be substantial differences in size distortion according to which univariate time series is tested for the presence of a unit root.

Published: April 2016

(1) Background: In 2011, new chronic disease guidelines were introduced across Mongolia. No formal advice was provided regarding role delineation. This study aimed to analyse the roles that different primary care providers adopted, and the variations in these, in the implementation of the guidelines in urban Mongolia; (2) Methods: Ten group interviews with nurses and ten individual interviews each with practice doctors and practice directors were conducted. Data was analysed using a thematic approach based on the identified themes relevant to role delineation; (3) Results: There was some variability and flexibility in role delineation. Factors involving teamwork, task rotation and practice flexibility facilitated well the guideline implementation. However, factors including expectations and decision making, nursing shortage, and training gaps adversely influenced in the roles and responsibilities. Some role confusion and dissatisfaction was identified, often associated with a lack of training or staff turnover; (4) Conclusions: Findings suggest that adequate ongoing training is required to maximize the range of roles particular provider types, especially primary care nurses, are competent to perform. Ensuring that role delineation is specified in guidelines could remove confusion and enhance implementation of such guidelines.
Debunking Two Myths of the Weekend Effect
Authors: Cheong Foong
Published: April 2016

This paper finds the weekend effect to be a remarkably robust anomaly and refutes the widespread belief that the weekend effect is due to data-mining or a consequence of some unusual/rare events. Out-of-sample analysis finds both the mean and median return on Monday is lower than that on Friday in nearly all years. It also reconciles and explains how some prior studies reached such an erroneous conclusion.
Challenging Density Functional Theory Calculations with Hemes and Porphyrins
Authors: De Visser Sam , Stillman Martin
Published: April 2016

In this paper we review recent advances in computational chemistry and specifically focus on the chemical description of heme proteins and synthetic porphyrins that act as both mimics of natural processes and technological uses. These are challenging biochemical systems involved in electron transfer as well as biocatalysis processes. In recent years computational tools have improved considerably and now can reproduce experimental spectroscopic and reactivity studies within a reasonable error margin (several kcal·mol−1). This paper gives recent examples from our groups, where we investigated heme and synthetic metal-porphyrin systems. The four case studies highlight how computational modelling can correctly reproduce experimental product distributions, predicted reactivity trends and guide interpretation of electronic structures of complex systems. The case studies focus on the calculations of a variety of spectroscopic features of porphyrins and show how computational modelling gives important insight that explains the experimental spectra and can lead to the design of porphyrins with tuned properties.
Interleukin-17A Differentially Induces Inflammatory and Metabolic Gene Expression in the Adipose Tissues of Lean and Obese Mice
Authors: Qu Yine , Zhang Qiuyang , Ma Siqi , Liu Sen , Chen Zhiquan , Mo Zhongfu , You Zongbing
Published: April 2016

The functions of interleukin-17A (IL-17A) in adipose tissues and adipocytes have not been well understood. In the present study, male mice were fed with a regular diet (n = 6, lean mice) or a high-fat diet (n = 6, obese mice) for 30 weeks. Subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) were analyzed for IL-17A levels. SAT and VAT were treated with IL-17A and analyzed for inflammatory and metabolic gene expression. Mouse 3T3-L1 pre-adipocytes were differentiated into adipocytes, followed with IL-17A treatment and analysis for inflammatory and metabolic gene expression. We found that IL-17A levels were higher in obese SAT than lean SAT; the basal expression of inflammatory and metabolic genes was different between SAT and VAT and between lean and obese adipose tissues. IL-17A differentially induced expression of inflammatory and metabolic genes, such as tumor necrosis factor α, Il-6, Il-1β, leptin, and glucose transporter 4, in adipose tissues of lean and obese mice. IL-17A also differentially induced expression of inflammatory and metabolic genes in pre-adipocytes and adipocytes, and IL-17A selectively activated signaling pathways in adipose tissues and adipocytes. These findings suggest that IL-17A differentially induces inflammatory and metabolic gene expression in the adipose tissues of lean and obese mice.
Integrated Utilization of Sewage Sludge and Coal Gangue for Cement Clinker Products: Promoting Tricalcium Silicate Formation and Trace Elements Immobilization

Published: April 2016

The present study firstly proposed a method of integrated utilization of sewage sludge (SS) and coal gangue (CG), two waste products, for cement clinker products with the aim of heat recovery and environment protection. The results demonstrated that the incremental amounts of SS and CG addition was favorable for the formation of tricalcium silicate (C3S) during the calcinations, but excess amount of SS addition could cause the impediment effect on C3S formation. Furthermore, it was also observed that the C3S polymorphs showed the transition from rhombohedral to monoclinic structure as SS addition was increased to 15 wt %. During the calcinations, most of trace elements could be immobilized especially Zn and cannot be easily leached out. Given the encouraging results in the present study, the co-process of sewage sludge and coal gangue in the cement kiln can be expected with a higher quality of cement products and minimum pollution to the environment.

Authors: Tomo Tito , Somlor Sophon , Schmitz Alexander , Jamone Lorenzo , Huang Weijie , Kristanto Harris , Sugano Shigeki
Published: April 2016

This paper presents an easy means to produce a 3-axis Hall effect–based skin sensor for robotic applications. It uses an off-the-shelf chip and is physically small and provides digital output. Furthermore, the sensor has a soft exterior for safe interactions with the environment; in particular it uses soft silicone with about an 8 mm thickness. Tests were performed to evaluate the drift due to temperature changes, and a compensation using the integral temperature sensor was implemented. Furthermore, the hysteresis and the crosstalk between the 3-axis measurements were evaluated. The sensor is able to detect minimal forces of about 1 gf. The sensor was calibrated and results with total forces up to 1450 gf in the normal and tangential directions of the sensor are presented. The test revealed that the sensor is able to measure the different components of the force vector.

Issues to Be Solved for Energy Simulation of An Existing Office Building
Authors: Ahn Ki , Kim Deuk , Kim Young , Yoon Seong , Park Cheol
Published: April 2016

With the increasing focus on low energy buildings and the need to develop sustainable built environments, Building Energy Performance Simulation (BEPS) tools have been widely used. However, many issues remain when applying BEPS tools to existing buildings. This paper presents the issues that need to be solved for the application of BEPS tools to an existing office building. The selected building is an office building with 33 stories above ground, six underground levels, and a total floor area of 91,898 m2. The issues to be discussed in this paper are as follows: (1) grey data not ready for simulation; (2) subjective assumptions and judgments on energy modeling; (3) stochastic characteristics of building performance and occupants behavior; (4) verification of model fidelity-comparison of aggregated energy; (5) verification of model fidelity-calibration by trial and error; and (6) use of simulation model for real-time energy management. This study investigates the aforementioned issues and explains the factors that should be considered to address these issues when developing a dynamic simulation model for existing buildings.
TOWARDS EXPERIENTIAL REPRESENTATION IN ARCHITECTURE
Authors: Suárez Luis Alfonso de la Fuente
Published: April 2016

Planning and predicting the experiences that buildings will produce is an essential part of architectural design. The importance of representation lies in its ability to communicate experiences before a building is materialized. This article will treat the topic of representation of architecture works without putting aside our direct experience with edifices. By understanding the perceptual, associative and interactive phenomena that arise from the human encounter with buildings, it becomes possible to comprehend the representation of these phenomena through pictorial means. The first objective of this theoretical article is to define the inherent and unavoidable factors that are present in the creation and interpretation of all architectural representations, regardless of the technical means used. Any representation conveys two processes: the representation of experience (a creative process), and the experience of representation (an interpretive process). Furthermore, there exist two layers in any representation: the what (the architectural object) and the how (the representational medium). The second objective is to suggest alternatives to visual realism, in order to create representations that embody the particular phenomena that an architectural work will be able to produce. On the one hand, representations that pretend to copy reality produce in the observers detailed visual experiences; on the other hand, certain representations reflect the experiences themselves after they have been produced; they represent buildings as they are transformed by experience. This article focuses on those representations that are not only the reflection of an object, but also the reflection of our way of experiencing it.
EFFICIENT GEOMETRIC PROBABILITIES OF MULTI-TRANSITING EXOPLANETARY SYSTEMS FROM CORBITS
Authors: Brakensiek Joshua , Ragozzine Darin
Published: April 2016

NASA’sKepler Space Telescopehas successfully discovered thousands of exoplanet candidates using the transit method, including hundreds of stars with multiple transiting planets. In order to estimate the frequency of these valuable systems, it is essential to account for the unique geometric probabilities of detecting multiple transiting extrasolar planets around the same parent star. In order to improve on previous studies that used numerical methods, we have constructed an efficient, semi-analytical algorithm called the Computed Occurrence of Revolving Bodies for the Investigation of Transiting Systems (CORBITS), which, given a collection of conjectured exoplanets orbiting a star, computes the probability that any particular group of exoplanets can be observed to transit. The algorithm applies theorems of elementary differential geometry to compute the areas bounded by circular curves on the surface of a sphere. The implemented algorithm is more accurate and orders of magnitude faster than previous algorithms, based on comparisons with Monte Carlo simulations. We use CORBITS to show that the present solar system would only show a maximum of three transiting planets, but that this varies over time due to dynamical evolution. We also used CORBITS to geometrically debias the period ratio and mutual Hill sphere distributions ofKepler's multi-transiting planet candidates, which results in shifting these distributions toward slightly larger values. In an Appendix, we present additional semi-analytical methods for determining the frequency of exoplanet mutual events, i.e., the geometric probability that two planets will transit each other (planet–planet occultation, relevant to transiting circumbinary planets) and the probability that this transit occurs simultaneously as they transit their star. The CORBITS algorithms and several worked examples are publicly available.
COSMIC REIONIZATION ON COMPUTERS: NUMERICAL AND PHYSICAL CONVERGENCE
Authors: Gnedin Nickolay Y.
Published: April 2016

In this paper I show that simulations of reionization performed under the Cosmic Reionization On Computers project do converge in space and mass, albeit rather slowly. A fully converged solution (for a given star formation and feedback model) can be determined at a level of precision of about 20%, but such a solution is useless in practice, since achieving it in production-grade simulations would require a large set of runs at various mass and spatial resolutions, and computational resources for such an undertaking are not yet readily available. In order to make progress in the interim, I introduce a weak convergence correction factor in the star formation recipe, which allows one to approximate the fully converged solution with finite-resolution simulations. The accuracy of weakly converged simulations approaches a comparable, ~20% level of precision for star formation histories of individual galactic halos and other galactic properties that are directly related to star formation rates, such as stellar masses and metallicities. Yet other properties of model galaxies, for example, their H i masses, are recovered in the weakly converged runs only within a factor of 2.
L’image, entre simulacre et vérité
Authors: Christopoulou Vassiliki-Piyi
Published: April 2016

Le but de cet article est de proposer une réflexion transversale, historique et notionnelle, sur ce qu’on pourrait appeler « les prestiges de l’image » (Paul Ricoeur) tout autant que le discrédit qui pèse sur elles, de Platon à Freud. L’image- eikon, étroitement associée chez les Grecs à la notion de vérité- aléthéia (absence d’oubli) n’est pas moins frappée de suspicion, comme « art du simulacre », à l’instar de ces « ombres » dont se délectent à leur insu les fameux prisonniers de la caverne. Toutes ces conceptions ancestrales placent Freud et la psychanalyse, dans la riche tradition qui les précède tout autant que dans un rapport de subversion. De l’abandon de la neurotica jusqu’aux débats actuels autour des thèses de Serge Viderman, la notion de vérité, exhumée, construite ou reconstruite, ne cesse d’habiter, voire de « hanter » l’espace clinique mais aussi les dossiers les plus brûlants de notre actualité, à l’interface de l’individuel et du collectif.
Sur les diverses manières de dire non
Authors: Dubois Claude-Gilbert
Published: April 2016

Il existe une analogie de structure et de fonctionnement entre la vie publique, dont l’étude ressortit aux sciences humaines du collectif, et la vie privée, dont l’étude ressortit à la psychologie et aux sciences de l’individu, parce que ce sont les individus qui forment les collectivités. Cet article présente une série de cas empruntés à ceux qui « disent non » à la société ou à un régime politique, puis quelques cas de ceux qui se « disent non » à eux-mêmes. Le dosage réussi entre ce qui « dit oui » et ce qui « dit non » en chacun débouche sur un équilibre des pouvoirs dans la vie publique, ou un équilibre des instances de la personnalité. Cet équilibre n’est pas donné, mais il peut s’apprendre.
L’incestuel à la 2 e génération
Authors: Villagra Julio
Published: April 2016

C’est une réflexion sur un sujet difficile et complexe : les conséquences des faits incestueux sur la génération qui suit (enfants de parents incestés). L’article montre les répercussions destructrices sur le psychisme des enfants, du fait de la rencontre entre ce qui devait rester inconscient et ce qui vient se mettre en acte. Ainsi l’inceste en acte provoque le surgissement d’un climat incestuel, d’une atmosphère qui attaque les êtres dans leur corps, leur psychisme, leur identité, leurs vies sexuelles.
Une force contre une autre force, éloge de la résistance inconsciente
Authors: Fos-Falque Sabine
Published: April 2016

La démonstration ici tente à poser la résistance comme point d’appui, dont on rêverait certes de pouvoir se passer. Ce qui résiste fait pourtant force. Moteur de la cure au sens ou par elle et sur cette résistance même prennent appui tous les conflits antérieurs. Le sujet y trouve un bord, une butée qui le révèle à lui-même. Si sa force ne rencontrait pas une autre force mais une présence inconsistante et floue, à quoi pourrait-il s’adosser ? Le divan est souple, voir moelleux, mais sa fermeté donne soutènement au dos en son entier. L’interprétation qui décale et déplace propose une force comme sortie de l’enlisement, forme d’assaut par le sens. Un sens qui fait tenir debout et savoir se relever du divan.

Depuis plusieurs décennies, le mythe de la famille nucléaire stable se parcellise en une mosaïque de modèles familiaux. De nombreux référents symboliques qui structuraient les liens de couple, les liens de filiation et les liens fraternels aujourd’hui se perdent, laissant souvent place à un espace faiblement différencié entre sexes et générations. Cet effacement trouve un écho chez l’enfant comme chez l’adulte, les empêchant de renoncer à la toute-puissance narcissique. Face à des symptômes qui s’origine de plus en plus dans l’archaïque, vers quels nouveaux outils cliniques le psychanalyste peut-il se tourner ?
L’enfant en danger pris entre les filets d’Eros et les reflets de Narcisse

Un danger court-il autour de l’enfant désiré, l’enfant roi serait-il un enfant mal aimé parce qu’aimé de l’amour « d’Eros », car en réalité l’amour respectueux et distancié d’un enfant sujet et en devenir, ne serait ce pas l’amour « philia ». Nous pourrions aujourd’hui avoir peur de cet enfant idole comme autrefois nous avons craint le père c’est à dire celui qui occupait trop de place et détenait trop de pouvoir. L’enfant est en danger d’être sacralisé et, à ce titre sacrifié dans son devenir de sujet.
« Bug ! » : thérapie et/ou médiation familiale ?
Authors: Duret-Salzer Florence
Published: April 2016

Lorsqu’il y a « bug » dans la famille, tout l’enjeu pour les personnes concernées, est – en substance – de parvenir à comprendre ce qui fait bug. Le travail analytique et celui en médiation accompagnent avec ce même objectif : comment atteindre un meilleur bien-être, accepter le changement et dépasser le bug ? Si les deux démarches ont des objectifs communs, les voies du travail thérapeutique et de la médiation familiale me semblent dans l’ensemble bien distinctes. Cet article propose une réflexion sur les spécificités des différentes pratiques et ceci surtout pour entrer dans le détail de celles de la médiation familiale.

Social Network Analysis (SNA) looks at how our world is connected. The mapping and measuring of connections and interactions between people, groups, organizations and other connected entities are very significant and have been the subject of a fascinating interdisciplinary topic . Social networks like Twitter, Facebook, LinkedIn are very large in size with millions of vertices and billions of edges. To collect meaningful information from these densely connected graph and huge volume of data, it is important to find proper topology of the network as well as analyze different network parameters. The main objective of this work is to study network characteristics commonly used to explain social structures. In this chapter, we discuss all important aspect of social networking and analyze through a real time example. This analysis shows some distinguished parameters like number of clusters, group formation, node degree distribution, identifying influential leader/seed node etc. which can be used further for feature extraction.
A Network Analysis Method for Tailoring Academic Programs
Authors: Casillas Luis , Daradoumis Thanasis , Caballe Santi
Published: April 2016

Producing or updating an academic program implies a significant effort: involving people, academic units, knowledge elements, regulations, institutions, industry, etc. Such effort entails a complexity related to the volume of elements involved, the diversity of the origins of contributions, the diversity of formats, the representation of information, and the required granularity. Moreover, such effort is a common task performed by humans who collaborate for long periods of time participating in frequent meetings in order to achieve agreement. New educational approaches are heading to adaptive, flexible, ubiquitous, asynchronous, collaborative, hyper-mediated, and personalized strategies based on modern Information and Communication Technologies (ICT). We propose an approach for tailoring academic programs to provide a practical and automated method to discover and organize milestones of knowledge through the use of Complex Networks Analysis (CNA) techniques. Based on indicators from CNA, the act of tailoring an academic program acquires meaning, structure and even body elements.
Analysis and Comparison of Developed 2D Medical Image Database Design using Registration Scheme, Retrieval Scheme, and Bag-of-Visual-Words
Authors: Ayyachamy Swarnambiga
Published: April 2016

There is certain to be a significant increase in the use of registration, retrieval and registration based retrieval of medical images in healthcare. But there is a related major concern that these initiatives are narrowly policy or technology led rather than evidence based or case based reasoning. Or else, either they will be based on old paradigm structures without considering the new paradigms that they create. It is planned to look at the image registration and retrieval from a unified perspective based on their performance for clinical diagnosis and treatment. It is concluded with an experiment carried out on histopathology and five types of anatomic (radiology) images. The results showed that this approach works better with more images from the Bag-Of-Visual words and Affine with B-Spline registration based retrieval for modality and histopathological images. Bag-of-Visual Words is more suitable for histopathological images than registration based retrieval techniques.

Authors: Guo Z.X. , Yang Jing , Chen Longchao , Guo Ruiqiang
Published: April 2016

This paper proposes an information system framework for production collaboration and standardization in Chinese liquor industry, and examines the key implementation issues of information systems in Chinese liquor production. A descriptive single case study is conducted to explore and identify the benefits, challenges, and success factors of information system implementation in Chinese liquor production by taking a famous Chinese liquor producer as the target case company. The case study shows that the proposed information system framework is helpful to improve collaboration and standardization in Chinese liquor production. Some benefits and challenges of implementing information systems are different from those described in previous studies because of various distinct, real-world features of Chinese liquor production. The proposed system framework offers the possibility to improve the Chinese liquor producer's production efficiency and market competition by better production collaboration and standardization.

Green marketing is one of the emerging fields in India. Educated young consumers are very advantageous segment for green marketing. This paper aims to evaluate the purchase behavior and reactions of educated young consumers towards ‘green products' which is an essential element of the green marketing. Various variables have been found on the basis of the literature review. The survey questionnaire was designed with the help of literature and expert's inputs and got 343 actual respondents. An exploratory factor analysis and linear regression analysis has been used to bring the findings of the study. The result of the study shows that EYCs (Educated young consumers) purchase behavior towards green product is positive. Green product awareness, Eco-labels and satisfaction and all these found significantly associated with the purchase behavior or intention, but premium price and consumer (those who are highly concern towards environment) has insignificant relationship with the purchase behavior. The concept of green marketing in India is emerging and the study can be a meaningful guide.

Published: April 2016

The current paper provides an overview on how user modeling, context awareness and content adaptation in Smart Home environments may be handled formally in order to capture the semantics that emerge from a newly introduced user experience: SandS is in fact a complete ecosystem of users within a social network, creating and exchanging content in the form of so-called recipes and developing a collective intelligence which adapts its operation through appropriate feedback provided by the user. The authors will approach SandS from the user's perspective and illustrate how users and their relationships can be modeled through a number of fuzzy stereotypical profiles. Additionally, context modeling in pervasive computing systems and especially in the Smart Home paradigm will be examined through appropriate representation of context cues in the overall interaction. Finally, the authors will investigate how users and system services although using languages of different semantic expressiveness can inter-operate successfully thanks to appropriate knowledge-based expert mappings.

Published: April 2016

Testing the clinical efficacy of drugs that also have important side effects on locomotion needs to be properly designed in order to avoid erroneous identification of positive effects when the evaluation depends on motor-related tests. One such example is the evaluation of analgesic role of drugs that act on dopaminergic receptors, since the pain perception tests used in animal models are based on motor responses that can also be compromised by the same substances. The apparent analgesic effect obtained by modulation of the dopaminergic system is still a highly disputed topic. There is a lack of acceptance of this effect in both preclinical and clinical settings, despite several studies showing that D2/3 agonists induce antinociception. Some authors raised the hypothesis that this antinociceptive effect is enhanced by dopamine-related changes in voluntary initiation of movement. However, the extent to which D2/3 modulation changes locomotion at analgesic effective doses is still an unresolved question. In the present work, we performed a detailed dose-dependent analysis of the changes that D2/3 systemic modulation have on voluntary locomotor activity and response to four separate tests of both thermal and mechanical pain sensitivity in adult rats. Using systemic administration of the dopamine D2/3 receptor agonist quinpirole, and of the D2/3 antagonist raclopride, we found that modulation of D2/3 receptors impairs locomotion and exploratory activity in a dose-dependent manner across the entire range of tested dosages. None of the drugs were able to consistently diminish either thermal or mechanical pain perception when administered at lower concentrations; on the other hand, the larger concentrations of raclopride (0.5–1.0 mg/kg) strongly abolished pain responses, and also caused severe motor impairment. Our results show that administration of both agonists and antagonists of dopaminergic D2/3 receptors affects sensorimotor behaviors, with the effect over locomotion and exploratory activity being stronger than the observed effect over pain responses.
The spectrum of a Schrödinger operator with small quasi-periodic potential is homogeneous
Authors: Damanik David , Goldstein Michael , Lukic Milivoje
Published: April 2016

We consider the quasi-periodic Schrödinger operator

[H \psi] (x) = -\psi''(x) + V(x) \psi(x)

in

L^2(\mathbb R)

, where the potential is given by

V(x) = \sum_{m \in \Z^\nu \setminus \{ 0 \}} c(m)\exp (2\pi i m \omega x)

with a Diophantine frequency vector

\omega = (\omega_1, \dots, \omega_\nu) \in \mathbb R^\nu

and exponentially decaying Fourier coefficients

|c(m)| \le \varepsilon \mathrm {exp} (-\kappa_0|m|)

. In the regime of small

\varepsilon > 0

we show that the spectrum of the operator

H

is homogeneous in the sense of Carleson.
El monumento como documento para su historia Restauración del Acueducto de Morelia en México
Authors: Cabrera Acevea Juan , Ettinger Catherine R.
Published: April 2016

La relación entre la arquitectura y la historia de un monumentose hizo evidente conforme avanzaba el proceso de restauración del acueducto de Morelia en México. La intervención planteó cuestiones de trascendencia relativas al origen de la construcción, que habitualmente se databa a finales del siglo XVIII. La observación cuidadosa de las marcas de cantero, la dimensión de los arcos y las técnicas empleadas en el labrado de los sillares dio como resultado el redescubrimiento de un acueducto que había sido objeto de transformaciones durante los últimos cuatrocientos años y, finalmente, destacó la importancia de la lectura del edificio como documento de la historia.

Consolidación y protección de las termas romanas de Sant Boi de Llobregat (Barcelona)
Authors: González Antoni
Published: April 2016

A pesar de los avatares sufridos por sus fábricas, las termas romanas de Sant Boi se cuentan entre las mejor conservadas de Cataluña. Los criterios con los que el SPAL acomete su restauración, tras un riguroso estudio pormenorizado e interdisciplinar, son: la conservación y puesta en valor de sus restos; la protección de las mismas mediante un edificio que facilite la visita; y la disposición de gradas y un recorrido externo a los restos para evitar su deterioro y permitir un uso didáctico del conjunto.
El tapiz de Penélope continúa restauración del Palacio Abacial de Alcalá la Real
Authors: Quesada García Santiago
Published: April 2016

La rehabilitación de este palacio característico de la Baja Andalucía representa un episodio añadido a su abigarrada historia, que el autor imagina como un lienzo entreverado de acontecimientos diversos que han enriquecido paulatinamente su urdimbre constructiva. Su artículo aspira a documentar y justificar la labor de tejido y deshilado que ha ejercido sobre el monumento histórico, como si de un mítico tapiz de Penélope se tratara. El texto, además, tiene a bien detenerse en los pormenores de las técnicas empleadas en el trenzado de sus nuevos mimbres.
El diseño y la construcción de armaduras lígneas de cubierta sobre obras de fábrica: Análisis de tres casos en la C. Valenciana
Authors: Palaia Pérez Liliana
Published: April 2016

Este artículo forma parte de una investigación más extensa que ha desvelado la riqueza de soluciones constructivas lígneas que caracteriza el Levante español. Si el conocimiento es previo a la valoración, bienvenidos sean estos estudios que abren todo un horizonte a la conservación beligerante de muchas cerchas de madera que, menoscabadas en la dignidad de su función estructural, se ven lastimosamente sustituidas por cuchillos metálicos -so color de su condición oculta- o reemplazadas por madera laminada -en aras de cumplimiento de la penúltima normativa-.
El teatro circo de Albacete
Authors: Gutiérrez Mozo Elia
Published: April 2016

El Teatro Circo de Albacete constituye uno de los edificios emblemáticos del despertar de la ciudad hacia la moderniad decimonónica. El doble e interesante carácter de teatro y circo, originalmente se evidenciaba en la posibilidad de conversión del patio de butacas en pista. Generada una encendida polémica con su rehabilitación, este artículo pretende aportar unas opiniones más serenas y disciplinares a partir de la reflexión acerca de la historia del edificio y de la filosofía que ha animado la intervención.

La restauración de la Villa Durante en Roma
Authors: Schiattarella Andrea
Published: April 2016

Quizás a causa de los innumerables monumentos que atesora Roma, en ocasiones, obras poco conocidas por el gran público, pero no por ello de menor valor o importancia, caen fácilmente en el olvido. Éste es el caso de la Villa Durante, espléndida residencia señorial, construida durante el fervor edilicio que siguió a la toma de Roma por parte de los bersaglieri1 en 1870 y su proclamación como capital de Italia2. El edificio, olvidado y abandonado durante años, ha sido restituido a su esplendor originario durante la reciente restauración que pasamos a describir.
La restauración del Mercado de Colón de Valencia
Authors: Martínez Díaz Enrique
Published: April 2016

Este mercado, actualmente enclavado en el núcleo de mayor actividad comercial de la ciudad, constituye un hito modernista dentro del panorama urbano del Ensanche. La necesidad de rehabilitar el edificio, revitalizar su función como mercado según los estándares actuales y dotar de los aparcamientos subterráneos de los que la zona es deficitaria han marcado las pautas de la intervención global en el Mercado de Colón, que se dividió en dos etapas: una primera fase de la cual trata este artículo, de restauración general y ampliación a tres sótanos de aparcamiento y un semisótano comercial, y una segunda fase que consistió en la habilitación posterior del mismo como espacio comercial contemporáneo.
