Forecastability of Earnings Surprises
Authors: Bulsiewicz James G.
Published: December 2020

I investigate whether it is possible to profitably trade on predicted earnings surprises, forecasted using the Foster (1977) model. Unlike the extant literature, which documents a strong positive relation between actual earnings surprises and returns, I find that trading on predicted earnings surprises, generated by the Foster (1977) model, has earned a small negative, but statistically indistinguishable from zero, return. This result highlights the difficulty in forecasting earnings surprises.

Apresentação do dossiê: materialidades e agências na América afro-latina
Authors: Cruz Alline Torres Dias da , Toledo Magdalena Sophia Ribeiro de
Published: December 2020

Este texto se baseia em pesquisas etnográficas sobre as relações de pessoas e coletivos afrodescendentes no Caribe e na América Latina com monumentos, artefatos, performances, ‘obras de arte’, ‘coleções’, alimentos, seres espirituais, ‘naturais’ e paisagens. Discute como, nas socialidades afro-diaspóricas, os processos e práticas de pertencimento ancestral, de recriação e transformação de si, de reparação e libertação lidam com materialidades e agências que estão articuladas a historicidades constituídas por uma miríade de agentes e instituições convencionalmente ditas "modernas". Para isso, debate como, em certas vertentes clássicas e contemporâneas da chamada "antropologia afroamericana", tais articulações reverberadas por uma antropologia do Caribe foram desconsideradas.
Alçar os santos dos calabouços: um museu para a liberdade
Authors: Rodríguez Cáceres Luz Stella
Published: December 2020

Duas coleções de objetos religiosos afro-brasileiros que foram confiscados pela polícia entre 1891 e as primeiras décadas do século XX são objeto de reflexão neste artigo. Ao estudar os percursos dessas coleções foram mapeados os diversos valores de sentido atribuídas a elas, os quais longe de serem permanentes, também não são excludentes entre si. Proponho discutir os processos simbólicos e arranjos institucionais que foram acionados ao longo das suas trajetórias. Nessa empreitada, essas coleções são passíveis de serem analisadas em duas dimensões: por um lado, enquanto realidade subjetiva, afetiva e cosmológica; e por outra parte como objetos de luta política na esfera pública de um coletivo socialmente organizado. Ambas as coleções possuem origens similares e têm como denominador comum a exigência das pessoas envolvidas de que seja o museu a instituição encarregada de as abrigar. O museu é indicado como o lugar para a reparação da dor e do sofrimento causados pela violência e intolerância religiosa, o racismo e o preconceito. Em ambos os casos é abordado o poder de agência desses conjuntos de objetos que tem materializado ações e provocado mobilizações em torno de si.
Nos rastros de Hyppolite: a pintura popular haitiana entre religião e arte
Authors: Goyatá Júlia Vilaça
Published: December 2020

Este artigo, baseado em uma etnografia com documentos históricos, procura refletir sobre as práticas de construção da chamada “arte popular” no Haiti da metade do século XX. Para tal, acompanha a criação e os primeiros anos de funcionamento do Centre d’Art, centro de produção e divulgação das artes plásticas haitianas criado em 1944, e a circulação de suas primeiras exposições para o exterior. Dá-se ênfase especialmente à narrativa articulada pela instituição em torno do célebre pintor e sacerdote vodu Hector Hyppolite (1894- 1948) que, argumento, é tido ele mesmo como uma espécie de artefato em circulação. O trabalho e a própria figura de Hyppolite funcionam, assim, como a imagem condensada de um “Haiti popular” que se queria projetar naquele momento, marcado por suas raízes africanas expressas tanto no campo religioso quanto artístico.
Corpos/paisagens no pacífico negro Colombo-Equatoriano
Authors: Melo Paula Balduino de
Published: December 2020

Este artigo aborda o trabalho das mulheres na constituição de corpos/paisagens no Pacífico Negro Colombo-equatoriano. Para tal, versa sobre a centralidade das águas nas vivências e elaborações da territorialidade; sobre a comida como um lugar de encontros e agenciamentos; sobre a mariscagem como uma relação estabelecida pelas mulheres entre elas, as águas e diversos seres hidrobiológicos; sobre as agencialidades que habitam os rios em formas de encantados, pedras e ouro. Adota-se como base epistemológica as narrativas construídas na experiência etnográfica junto às mulheres afro-pacíficas, que em sua maioria são matronas, autoridades familiares e comunitárias que constroem redes de irmandade política e afetiva, conectando o doméstico e o público. Tal concepção sustenta-se na compreensão de que a experiência vivida é fonte de produção de conhecimento e que a produção de conhecimento entre povos afrodiaspóricos traz uma perspectiva coletiva, tendo por vezes a oralidade como plataforma de existência.
Fragmentos de história e composições etnológicas: marcas indígenas nos caminhos das Minas
Authors: Mano Marcel
Published: December 2020

O artigo se apoia em dados marginais da história para reconstruir um problema etnológico: a classificação cultural de grupos indígenas mencionados nas fontes do século XVIII nas regiões dos atuais Triângulo Mineiro e Alto Paranaíba. Essas sobras, garimpadas ao longo de uma vasta documentação, tal como ensina o paradigma indiciário, são reveladoras de alguns equívocos e distorções da antropologia e história indígena regional. A partir do reconhecimento de homologias entre essas sobras e sinais oriundos de outros domínios, como a arqueologia e a etnologia, o artigo problematiza e relativiza a filiação Tupi atribuída a alguns dos grupos mencionados nas fontes. Lidos à luz da etnologia contemporânea, os dados documentais ganham nova inteligibilidade e apresentam fortes indícios para uma revisão interpretativa de antigas versões.
The analysis and design of and the evaluation of design actions for reinforced concrete ductile shear wall structures
Authors: Paulay T. , Williams R. L.
Published: December 2020

A comprehensive review of the state of the art in the design of earthquake resisting ductile structural walls is presented. The material has been compiled from the technical literature, the deliberations within the New Zealand National Society for Earthquake Engineering and research efforts at the University of Canterbury. The paper attempts a classification of structural types and elaborates on the hierarchy in energy dissipation. After a review of available analysis procedures, including modelling assumptions, a detailed description of capacity design procedures for both cantilever and coupled shear wall structures is given. The primary purpose of capacity design is to evaluate the critical design actions which can be used in the proportioning and reinforcing of wall actions which can be used in the proportioning and reinforcing of wall sections. An approach to the estimation of structural deformation is suggested. To satisfy the ductility demands imposed by the largest expected earthquake, detailed design and detailing recommendations are given and the application of some of these is presented in an appendix.

Using Fine Silica Sand and Granite Powder Waste to Control Free Swelling Behavior of High Expansive Soil
Authors: Suliman Manal O. , Alkherret Abdulrazzaq Jawish
Published: December 2020

Many researchers have been interested in studying the effect of adding local natural materials or construction waste on the properties of poor subgrade soil. However, changes in size and strength of expansive soils can cause extensive damage to the geotechnical infrastructure. This damage is often repeatable and latent in the long term, and is a critical issue in highway subgrade engineering. This paper examines the effect of adding both Fine Silica Sand (FSS) and Granite Cutting Powder Waste (GPW) materials on the welling characteristics of expansive soils. Atterberg limits, free swell index, and rate of swell of the mixtures were used as a key to assess properties of a group of expansive soil samples after adding different percentages of the mentioned materials. The rates of additions were 10%, 20%, 30%, 40%, 50%, 60 and 70% of the weight of the soil samples. The test results showed that FSS and GPW significantly affect the expansive soil properties. However, adding 70% of both FSS and GPW reduced the swelling index from 58.3% to 6.6% and from 58.3% to 11% after 7 days of curing, respectively. This study suggests that the Fine Silica Sand and Granite Powder Waste can be used as stabilizers for expansive highly plastic soils.

Een decennium oordelen over doorlopende kredieten: uiteenlopende interpretaties van het contractuele rentewijzigingsbeding

Recent hebben zowel de Commissie van Beroep financiële dienstverlening als diverse rechters uitspraken gedaan over rentewijzigingsbedingen. Dergelijke bedingen gebruikten kredietverstrekkers van doorlopende kredietovereenkomsten om de variabele rente van die kredieten aan te passen. De uitspraken markeren de verschuiving van een nadruk op contractvrijheid en marktwerking naar de focus op een zekere mate van marktregulering en consumentenbescherming. In deze bijdrage wordt uiteengezet via welke weg deze verschuiving het afgelopen decennium heeft plaatsgevonden en wordt bijzondere aandacht gegeven aan de huidige stand van zaken, waarin twee wegen te herkennen zijn. Door de Commissie van Beroep is het beding uitgelegd – zodat consumenten mochten verwachten dat hun rente in de pas zou blijven met de marktrente. In de rechtspraak is in veel gevallen besloten tot vernietiging van het beding. Geconcludeerd wordt welke van de beide oordelen het meest overtuigt.
Career Adaptability – preliminary verification of the concept and measurement method
Authors: Paszkowska-Rogacz Anna
Published: December 2020

The aim of the article is to present the assumptions of the concept of the career adaptability of Mark Savickas and to present the psychometric properties of the Polish version of the Career Adapt-Ability Scale. It consists of five dimensions: concern, control, curiosity, confidence and cooperation. The analyzes were carried out with the participation of young adults (N = 664; 63% women, 37% men) aged 18 to 34 years (M = 24.4, SD = 2.9). The reliability of the tool was assessed on the basis of internal consistency method. Evidence of construct validity was obtained through confirmatory analysis and correlation with other, conceptually related variables such as social participation and tolerance of ambiguity in a career decision situation, measured using four indicators – preference, tolerance, confidence, and aversion. The results obtained indicate very good psychometric properties of the questionnaire. A high level of career adaptability is characteristic for two types of social participation – integration and assimilation. The higher intensity within all five components of Career Adapt-Ability Scale is also accompanied by a stronger acceptance of unknown, complex, inconsistent and unpredictable information when professional decisions are made.
Occupational themes, ambiguity tolerance level and coping strategies in career decision-making
Authors: Wągrowska Julia
Published: December 2020

The process of career adaptation is counted as a very significant topic, especially regarding career counseling. The aim of that article was to analyze the dependence between type of vocational personality, ambiguity tolerance level and styles of coping with career indecision making. There have been 227 students examined. Each of the examined individuals has got a vocational type of personality referring to gained outcomes from WOPZ questionnaire based on J.L. Holland’s model of vocational personality. Types of vocational personality have been being analyzed according to ambiguity tolerance in career decisions making (by using The Career Decision Ambiguity Tolerance Scale, CDAT) and strategies of coping with career indecision (with usage of Coping with Career Decision-making Difficulties, CCDD). The study has revealed that gender is not associated with personal dispositions as those mentioned above. Individuals characterized by Social type of vocational personality tend to seek help more often than those characterized by other types of vocational personality. Artistic type turned out to be linked to unproductive style of coping with career indecision more than any other type of vocational personality while individuals described as Enterprising type tend to have reversed tendency. Moreover, the present study has indicated that dependence between ambiguity tolerance and productive style of coping with career decisions making does occur.

Authors: Michalska Pauina , Szymanik-Kostrzewska Anna
Published: December 2020

Currently, in research on school readiness of children, more and more attention is paid to the socio-emotional competences of children, as well as looking for factors positively correlating with high results obtained in standardized tests. The aim of the study was to determine the emotional and motivational level of school readiness of 6-year-old children based on objective measurement using the Intelligence and Development Scales (IDS) and subjective measurement in the assessment of children’s mothers, using the “Parental Readiness Assessment Questionnaire”, based on IDS in terms of content, as well as determining the mutual relationship of results and the significance of controlled variables. 56 mothers and their children (aged 6;2–6;11 years old) were examined. Objective measurement showed average school readiness of children, subjective measurement – high. Correlations between them was on the verge of low, there was little correlation between the subscales of persistence and satisfaction with children’s achievements. For selected results, the parents’ education and age of children were significant.

Published: December 2020

Objective: To develop a comprehensive operative report schema based on the accuracy of primary operative reports (OpR) assessed on a department’s experience with parotid gland tumor re-operations.
Design: Retrospective cross-sectional study.
Setting: A tertiary referral center, the Department of Otolaryngology and Laryngological Surgery, Poznan University of Medical Sciences, Poland from 2008 to 2017.
Subjects: Out of 1154 surgeries, 71 patients underwent reoperation. Their OpR were categorized into accurate and non-accurate, and re-operation field and re-operation course were categorized as anticipated or unanticipated, according to defined criteria.
Intervention: None
Main outcome measures: The impact of accuracy of the first OpR on re-operation course.
Results: In this series, OpR were 39% (14/36) accurate, 61% (22/36) non-accurate. Re-operation fields were 16% (11/71) anticipated, 37% (26/71) unanticipated. Re-operation courses were 37% (26/71) anticipated, 63% (45/71) unanticipated. An anticipated re-operation course followed 20% (5/26) of accurate and 20% (5/26) of non-accurate primary OpR. An unanticipated re-operation course followed 20% (9/45) of accurate and 40% (18/45) of non-accurate OpR. There is no significant relationship between the re-operation course and accuracy of the first OpR (Chi2(1)=0.69; p=0.40466). The most common variable that affected non-accuracy of the OpR was facial nerve function after surgery (6/12).
Conclusions: The operative report should be based on clear criteria, robust classification and comprehensive protocol. This will improve follow-up and facilitate the planning of re-operation.

Alles schon gesagt? Gottfried Achenwalls Begründung des Naturrechts
Authors: Aichele Alexander
Published: December 2020

Abstract The Elementa Iuris Naturae of G. Achenwall have been one of the most common and most successful textbooks of natural law at German universities in the 18th century, not­withstanding its lack of originality concerning the foundation of natural law. On the contrary, the foundation given represents something like the (at that time) prevailing doctrine striving to base natural law on human nature as it is empirically conceived. The paper discusses Achenwall's use of this method and shows its considerable difficulties.
Autonomous Weapons Systems and International Law
Authors: Amoroso Daniele
Published: December 2020

Recent advances in robotics and AI have paved the way to robots autonomously performing a wide variety of tasks in ethically and legally sensitive domains. Among them, a prominent place is occupied by Autonomous Weapons Systems (or AWS), whose legality under international law is currently at the center of a heated academic and diplomatic debate. The AWS debate provides a uniquely representative sample of the (potentially) disruptive impact of new technologies on norms and principles of international law, in that it touches on key questions of international humanitarian law, international human rights law, international criminal law, and State responsibility.

Against this backdrop, this book’s primary aim is to explore the international legal implications of autonomy in weapons systems, by inquiring what existing international law has to say in this respect, to what extent the persisting validity of its principles and categories is challenged, and what could be a way forward for future international regulation on the matter. From a broader perspective, the research carried out on the issue of the legality of AWS under international law aspires to offer some more general insights on the normative aspects of the shared control relationship between human decision-makers and artificial agents.

VERB PATTERNS IN TRIAL DISCOURSE: THE CASE OF I THINK
Authors: Szczyrbak Magdalena
Published: December 2020

This study revisits the usage of I think in courtroom interaction based on transcripts from a murder trial. The analysis focuses on the structural diversity of I think and some of its variant forms, and it demonstrates pragmatic functions associated with the individual patterns. As the data reveal, I think performs the roles reported in earlier studies (discourse marker, hedge, booster, face-saving device, opinion marker, mindsay marker) as well as increases epistemic distance and decreases the degree of imposition in courtroom questioning. The findings obtained in the current research are also compared with Kaltenböck’s (2013) results documenting various uses of I think and other comment clauses in diachronic spoken data. This comparison demonstrates that, on the one hand, well-established patterns involving I think are frequent in the courtroom data and, on the other, that the recent trends with variant forms of I think – which have been identified in non-specialist settings – are scantily represented.
PHRASEOLOGY IN LEARNER ACADEMIC ENGLISH: CORPUS-DRIVEN APPROACHES
Authors: Malá Markéta
Published: December 2020

The paper combines learner corpus research with contrastive analysis to test the applicability of corpus-driven methods to the study of phraseology in learner academic English. It explores phraseological patterns in English L2 academic texts written by Czech university students in comparison with English L1 novice and expert writing. Three corpus-driven approaches are employed: frequency lists, keywords and lexical bundles. The results indicate that a combination of corpus-driven methods can indeed serve as an effective starting point for the contrastive study of phraseology, highlighting potentialareas of under- and overuse of multi-word patterns in English L2 novice academic texts. However, in order to give a more comprehensive picture of learner academic English, quantitative methods have to be combined with qualitative contrastive analysis.
Autonomy and Subordination
Authors: Pinto-Garay Javier , Scalzo Germán , Ferrero Ignacio ,   Philosophy Documentation Center
Published: December 2020

This paper aims to integrate the concept of autonomous and subordinated work into Aristotelian organizational theory by enhancing the epistemological framework of neo-Aristotelianism and by adding a Thomistic interpretation of organizational practical knowledge. We sustain that, in order to advance our understanding of the firm in terms of excellence and the common good, the concept of practical knowledge applied to organizational theory requires reflection on the nature of work in modern organizations. For this, we will explain (i) how an organization that aims for excellence is most appropriately defined as a community of autonomous work, (ii) how practical knowledge in organizations must be defined considering work as deliberative production and, finally, (iii) how productivity in organizations is best described when work is envisioned in terms of autonomy and subordination.

Published: December 2020

In agrarian production one of the most common technological operations is cutting of soil or plants. It makes up at least 70% of the total volume of mechanized works. The purpose of this study is to help maintain the agrotechnical parameters of the cultivator's blade by coating the blade with powder wear-resistant coatings using the one-sided gas-flame surfacing technology. The technology of strengthening the cultivator blade using one-sided gas-flame surfacing is applied. The technology of one-sided gas-flame surfacing guarantees an even reinforcing layer of the cultivator blade with a width of 10-12 mm and a layer thickness of 0.2 mm. With the development of gasometric spraying methods it is possible to atomize various materials such as polymers, carbides, metals. These coatings withstand the impact of high thermal loads, shock-abrasive and chemically active environments. Therefore, the addition of chromium carbide powder PG-12N-02 has a positive effect on the properties of the coating. It increases the durability and wear resistance of the cultivator blades. A saw-tooth blade is formed. Comparison of application methods mentioned above shows that the quality of coatings expressed in the parameters: adhesions, porosity, oxidation levels remain at approximately the same level. However, a comparative analysis of foreign practice has shown that the method of gas-flame surfacing is more technological, more productivity, and the specific costs of the coating are reduced.
IN-PROCESS PORTABLE PHOTOGRAMMETRY USING OPTICAL TARGETS FOR LARGE SCALE INDUSTRIAL METROLOGY
Authors: LEIZEA ALONSO IBAI , ZUBIZARRETA GOROSTIDI JON , MENDIKUTE GARATE ALBERTO , YAGUE FABRA JOSE ANTONIO
Published: December 2020

Portable photogrammetry methods are being used more and more as a 3D technique for large scale industrial metrology applications. Optical targets are placed on an object and images are taken around it, where measuring traceability is provided by precise off-process pre-calibrated digital cameras and scale bars. According to the 2D target image coordinates, target 3D coordinates and camera views are jointly computed. Numerical approaches such as bundle adjustment have usually been adopted for computing the 3D scene, with high computation time, leading in practice to time consuming and user dependent iterative review and re-processing measuring procedures until an adequate set of images is taken, limiting the potential of photogrammetry for fast, easy-to-use, and precise measurements. In a previous work, a new efficient computing procedure was presented for solving the bundle adjustment problem in portable photogrammetry. In this paper, further steps are presented towards increasing the computational efficiency of the in-process approach in portable photogrammetry. Measurement of raw part surface geometry prior to its machining is adopted as the industrial case for evaluation, with large scale measuring volumes (100 m3). An increase of efficiency in the in-process computing capability is demonstrated on a consumer grade desktop PC, with a total in-process computing time ranging 1 second per image for all the images taken at all the computed industrial scenarios. Additionally, a method for the self-calibration of camera and lens distortion is integrated into the in-process approach, enabling the use of low cost non-specialized digital cameras for precise industrial metrology, ranging at the same performance reported for portable photogrammetry with precise off-process pre-calibrated cameras, with a relative precision of 1/10,000 (e.g. 0.1 mm error in 1 m).

IMPLEMENTATION OF THE SMALL PUNCH TEST FOR THE MECHANICAL PROPERTIES ESTIMATION OF ALUMINUM ALLOYS
Authors: CALAF CHICA JOSE , BRAVO DIEZ PEDRO MIGUEL , PRECIADO CALZADA MONICA , GARCIA TARRAGO MARIA JOSE
Published: December 2020

The Small Punch Test (SPT) has aroused interest in the last years as a mechanical characterization test due to its simple geometry and the minimum required specimen volume. Its origin in the nuclear industry has motivated wide research focused on the evaluation of ferrous alloys, and there are few publications for other materials like non-ferrous alloys, ceramics and polymers. In this investigation, the application of the SPT in aluminum alloys has been evaluated in order to obtain master correlation curves to demonstrate the feasibility of this test to estimate the yield strength and the ultimate tensile strength. The most used correlation methods in the literature have been analyzed and the obtained results have shown the necessary reliability and repeatability to consider the SPT as an alternative test to the estimation of the mechanical properties in aluminum alloys.

Keywords: Small Punch Test, SPT, aluminum alloys, tensile test, yield strength, ultimate tensile strength.
SMOOTHING OF THE INTERMITTENT POWER PROVIDED BY WAVE POWER PLANTS USING ULTRACAPACITORS AND A NON-LINEAR VECTOR CURRENT CONTROLLED MMC
Authors: MARTINEZ RODRIGO FERNANDO , DE PABLO GOMEZ SANTIAGO , HERRERO DE LUCAS LUIS CARLOS , RAMIREZ PRIETO DIONISIO
Published: December 2020

This article focuses on smoothing the large power peaks that wave energy converters (WECs) inject into the electrical grid. The study is carried out for a single WEC where the generated power is delivered to the grid by means of a power converter. Two different measures have been considered to improve the power quality of the grid connection. Firstly, the electronic converter has been chosen a modular multilevel converter (MMC) to allow replacing the standard high voltage capacitors of the DC link by low voltage ultracapacitors distributed across the modules of the MMC. Secondly, the MMC is controlled using a non-linear vector current control. The results show that the power delivered to the grid becomes approximately constant when using ultracapacitors. Furthermore, the non-linear vector current source provides the grid connection converter with the necessary fast dynamic response to avoid large variations in the DC voltage.
Keywords: modular multilevel converter (MMC); non-linear vector current source; ultracapacitor; wave energy converter (WEC).
Valoración del profesorado en formación de educación infantil sobre su participación activa en itinerarios patrimoniales
Authors: López Fernández José Antonio , Fernández Terán Nuria
Published: December 2020

La investigación de lo que ocurre en las aulas de formación del profesorado de educación infantil cuando se trabaja el patrimonio cultural es todavía poco significativa con respecto a primaria y secundaria. En este artículo se presenta un análisis sobre las valoraciones de una propuesta concreta, con alumnado en formación inicial de educación infantil, participante en un itinerario didáctico de carácter patrimonial, donde éste interactúa en todos los procesos didácticos. El análisis se ha realizado en un grupo concreto, con 52 estudiantes de la Universidad de Córdoba. El objetivo es evaluar las aportaciones conceptuales y competenciales de esta práctica docente para la formación del futuro profesorado. Se trata de un estudio exploratorio y descriptivo, con dos herramientas para la toma de datos: un cuestionario semiestructurado y preguntas cerradas; y un estudio focal. Los resultados son bastante positivos, si bien es necesario seguir considerando una educación patrimonial globalizada e interdisciplinar, dejando de lado metodologías de contemplación y exaltación de lo monumental.
Experiencia de reflexión con un profesor de biología chileno acerca de su práctica de enseñanza

Published: December 2020

Las prácticas de enseñanza, por su naturaleza contextual y forma particular de implementarse, pueden favorecer o limitar los aprendizajes en el contexto escolar. En esa perspectiva, se diseña un estudio de caso que indaga en el contenido de la reflexión acerca de la práctica de enseñanza de un profesor de biología en servicio. Para ello, el profesor realiza una observación crítica de su práctica, comentando todas aquellas situaciones de enseñanza que le resultan preocupantes. Cada observación comentada fue profundizada a través de una entrevista focalizada. La información de las observaciones comentadas y entrevistas focalizadas fue analizada con el software Atlas-ti 8.0. De ahí emergieron preocupaciones docentes respecto a la enseñanza, consecuencias e implicancias para el aprendizaje de los estudiantes y dos dificultades de enseñanza en biología, que fueron: el uso de preguntas y la explicación docente. Se discuten los alcances de la reflexión como fuente generadora de conocimiento profesional

El objetivo de este trabajo es compartir una experiencia diseñada a partir de la explotación didáctica de la novela gráfica La casa (2015) de Paco Roca con un grupo de estudiantes de nivel B2. Tradicionalmente, el cómic se ha trabajado en el aula de ELE a partir de tiras cómicas o de secuencias breves. Sin embargo, en esta propuesta se reivindican las ventajas didácticas de este medio, sobre todo a partir de obras más extensas, para desarrollar el gusto estético y literario, favorecer la adquisición de estrategias de interpretación, elaborar inferencias y trabajar aspectos culturales y afectivos. Para lograrlo, a lo largo de la secuencia se presentan algunas de las obras más importantes del cómic en España, se ofrecen claves de lectura para sensibilizar al alumnado con las convenciones de este medio y se favorece la reflexión sobre la obra en relación con la experiencia personal.

Análisis de dos clavos y un rodamiento del pecio Bou Ferrer (La Vila-Joiosa, Alicante)
Authors: Moya José Antonio
Published: December 2020

Analizamos tres objetos de metal procedentes del yacimiento subacuático Bou Ferrer, dos clavos y un hipotético rodamiento de la bomba de achique. El interés surge por las dudas ante la apariencia física de los clavos que sugería la posibilidad de que fuesen de cobre o de bronce. Del tercer artefacto interesa conocer la composición para entender mejor su función mecánica. El resultado ha permitido conocer la composición de las tres piezas y ha revelado que el tipo de bronce utilizado en la fabricación del cojinete es una aleación ternaria, probablemente fabricada para mejorar su rendimiento.
El factor límite en la formulación del discurso del Bronce de La Mancha: los Montes de Toledo como modelo
Authors: Ruiz Taboada Arturo
Published: December 2020

Cuarenta años de investigación en La Mancha entre los que se encuentra mi tesis doctoral, han generado multitud de datos y teorías que tratan de explicar el desarrollo de la Edad del Bronce. Este artículo hace hincapié en los problemas derivados de una excesiva zonificación de la investigación y apuesta por la periferia como una de las claves para entender las diferentes dinámicas de ocupación del territorio. Determinar el papel del límite en relación con un centro cultural en las sociedades prehistóricas siempre ha sido objeto de debate. Dicho debate se incrementa al hablar de la Edad del Bronce peninsular, debido a su enorme atomización regional, sin que exista un consenso sobre sus límites e influencias.
INVESTIGATION OF URBAN TEXTURE AND ENERGY CONSUMPTION RELATIONSHIP IN THE CONTEXT OF URBAN TRANSFORMATION: KADIKÖY CASE STUDY
Authors: BEYAZTAŞ Halil
Published: December 2020

Turkey is undergoing a major transformation process. This process, also called urban renewal, takes place at neighborhood and building (on-site transformation) scales. The literature focuses on transformation problem of the neighborhood scale; however, the characteristics of the problems associated with building scale transformation differ. One of these is texture differentiation. With the on-site renewal process, the existing urban texture and its micro-climate characteristics change. An existing low-rise building in the street is transformed and built as a high-rise multi-storey building, which shades the neighboring buildings in the texture. In this case, it can be predicted that the energy consumption performance of existing buildings will be affected. The aim of this study is to examine the effect of reconstructed high-rise buildings on existing buildings in the texture in terms of energy performance. The study area is chosen as Suadiye (Kadıköy, Istanbul) because of the high urban renewal activity. Using computer simulation methodology, the energy performance of a reference building was calculated for three texture scenarios: base situation (rural texture), 1960 urban texture and 2019 texture (after renewal). In this study, in which the building envelope is kept constant, the effect of the urban texture on the building energy consumption is clearly observed. According to the results of the study, lighting and heating energy consumption of the reference building increased during the transition from rural to 1960 texture. With the urban transformation law numbered 6306 enacted in 2012, it would be possible to save energy by optimizing the urban texture. However, in practice, it is seen that energy consumption of the reference building is increased more in the transformation from the 1960 texture to the 2019 texture. In other words, texture change has increased energy consumption. One of the goals of this high-cost transformation process, which is necessarily experienced with earthquake risk in the first place, was stated as providing energy savings. For this purpose, envelope insulation is mandatory in reconstructed buildings. However, independent of the building envelope, the characteristics of the urban texture also play an important role in energy consumption. For this reason, the optimization of the urban texture should be evaluated as a part of the transformation process and legal regulations should be implemented to support this. Potential impact analysis should be done before intervening in the urban texture.
VIRTUAL NETWORK AS THE TECHNOLOGICAL LAYER OF THE PUBLIC SPACE AND ITS EFFECTS ON URBAN SPACES

Published: December 2020

The physical and representational contents of the public space are in a dynamic evolving state with the changes in the social structure and urban structure. In the historical process, the phenomenon of public space has been affected by the developments experienced with the change in the way individuals establish relationships in public life. Today, this transformation has occurred through virtual networks with the development of information and communication technologies. The paper aims to understand the public sphere dynamics that have changed with information and communication technologies. Accordingly, it limits its scope on these questions: How virtual networks affect the representational form of public space? What are the spatial structuring of this new representational public realm? What effect does this transformation have on urban areas that are the physical spaces of public realm? The method of the study is to explain theoretical discussions by supporting examples. In this context, it has been found that virtual networks, known as a new form of public space, transform the representative and physical form of the public space in a multifaceted manner by relocating the way individuals communicate with each other on a virtual layer. In this virtual transformation, it has been seen that the representative public space is now formed on social networks and platforms and the spatial structuring of these areas is defined as virtual network. The effect of virtual networks on the physical spaces of the public realm is possible by clustering data about urban areas in these virtual environments. Therefore, the visibility of virtual networks on the physical spaces of the publicity takes place through the understanding of space usage; moreover, virtual network data, which hybridizes with contemporary urban areas, reveals new qualities in the sense of the city by embodying it through maps. The physical transformation of the public space with information and communication technologies is made possible by the use of virtual network data in the design processes of this new sensory city.

Authors: ANDAÇ GÜZEL Tuğba , EFE Hacı Hasan
Published: December 2020

Ataturk Museum Pavilion formerly known as “Çankaya Mansion” is a building that has witnessed many important events of the history of the Republic of Turkey, and is one of the most important buildings that were put into service for Atatürk. This study covers the Dining Room which was added to the ground floor of the mansion after the renovation carried out between 1923-1924. This study is about the examination and scientific evaluation of the dining room in terms of interior and furniture. The dining room is a meeting place rather than a place used for dining in Ataturk's era. In this place, along with Atatürk, well-known and important personalities of that period came together. Many precious conversations affecting the history of the Republic of Turkey has hosted. As a result of the work carried out in the dining room, it was determined that the room was decorated in a mix of Renaissance, Baroque and Rococo style and in an original style. The furniture is carved in the same original style. Also, some of the examined furniture were found to be compatible with the numerical measurement values of today's furniture in terms of ergonomic and anthropometric criterias. As a result of the study, many new data obtained about the mansion have been added to the literature about the mansion.
Modelling & Simulation as a Strategic Tool for Decision-Making Process: A Dairy Case Study
Authors: Eccher Cristiani
Published: December 2020

The Dairy Industry faces many challenges compared to other sectors. On the supply side due to the nature of the raw material, large inventories are not applied; during the manufacturing process, the continuous production is highly sensitive to any sort of unplanned disruption; and on the demand side, the market dictates the commodity prices. In response to the growth in competition, dairy organizations’ strategy must incorporate technology into their daily processes in order to become more efficient, profitable and sustainable. To achieve desired levels of improvement, Modelling and Simulation has been increasing in popularity in the decision-making process. Using a Dairy company as a case study, this paper has highlighted the potential for Modelling and Simulation to be used as a powerful strategic tool for decision-making processes.
