Expressive Writing as Brief Psychotherapy
Authors: Algristian Hafid
Published: November 2019

AIM: To analyse the effect of expressive writing in three selected cases.
METHODS: Case studies presented from three psychiatric patients in a hospital-based outpatient clinic in Surabaya, Indonesia, between May 2017 and July 2018. Clinical changes have been observed and reported. Three patients were selected based on the possibility of whether they were able to or not to participate in similar cognitive therapy. These three cases were considered to represent a diagnosis for the psychotic and non-psychotic spectrum. The first case was a male with suicidal depression, the second was a woman with Suicidal Depression, and the third was schizophrenic woman elderly with auditory hallucinations. Expressive writing was formulated from literature studies and then implemented in these patients. Clinical changes were observed both associated with a reduction in symptoms as well as new symptoms. These non-directive measures allowed the author to observe the therapeutic effects and side effects of the intervention given.
RESULTS: Three cases were analysed. Targets were determined by patients themselves without author's intervention. Each patient underwent 10 sessions in minimum and 32 sessions in maximum, from once per week to once per two weeks, and was stopped after it was considered reaching or approaching the desired target, or if unwanted side effects appeared. Main changes were “father hunger” symptom decreased in the first patient, self-esteem increased in the second patient, and cope with auditory hallucination in the third patient. Few adverse events also have been recorded such as masturbation as an obsession ritual of the first patient, possibly provoked double-identity symptom in the second patient and mental fatigue in the elderly in the third patient.
CONCLUSION: Over six months of implementation, expressive writing show desirable results, yet some side effects in patients still need to be aware of.
A Case Series from Rantauprapat, La Belle Indifference: A Coping Mechanism or Is There Something Organic Behind?
Authors: Khaddafi Muhammad R. , Amin Mustafa M.
Published: November 2019

BACKGROUND: La belle indifference, a term that is inexhaustible to discuss, albeit there is no single definition that best describes the condition. To date, la belle indifference has gotten no place in the DSM-5 criteria for being a distinct entity of mental health issue.
CASE REPORTS: We reported 3 cases with la belle indifference. These patients include a stroke patient with right-sided hemiparesis, a patient suffering from neuropathic pain because of diabetic neuropathy, and a patient with cardiac dyspnea due to chronic heart failure — these three cases presented with a similar clinical profile that is the trigger for developing la belle indifference.
CONCLUSIONS: La belle indifference has varying symptom spectrum, and there is always something called “trigger” to induce it.

Authors: Alrebdi Yazeed Mohammad , Awadh Abdulrahman Khalid Ibn , Alfehaid Mohammad Saleh , Alsindi Abdullah Abdulaziz , Alaraj Ali
Published: November 2019

BACKGROUNDS: Sleep disorders and sleep medicine are underrecognized by both the general public and health care workers. Lack of education and training in sleep medicine has resulted in a culture of physicians who have very limited knowledge about sleep disorders and, as a result, are likely to underdiagnose and under-treat patients.
AIM: This study aimed to assess the knowledge of and attitude regarding sleep medicine among medical students at Qassim University.
METHODS: This was a cross-sectional study of 4th and 5th-year medical students, conducted at Qassim University (Central and Unaizah branches), Saudi Arabia. We used a self-administered data collection tool to collect personal information (age, name, sex, medical school), and assessed general attitude toward sleep medicine and the students’ current knowledge about sleep medicine using the Assessment of Sleep Knowledge in Medical Education (ASKME) survey.
RESULTS: The prevalence of medical students who had a special interest in sleep medicine was 23.3%. Poor knowledge about sleep medicine was detected in 94.8% of students, while good knowledge was observed in only 5.2%. The attitude of the students toward sleep medicine was negative among 40.5% and positive among 59.5%. University branches, gender, and preferred speciality were all significantly associated with attitude score, whereas interest in sleep medicine and knowledge of sleep disorders were associated with both knowledge and attitude scores.
CONCLUSION: This study found that medical students’ knowledge of sleep medicine was very low, despite the majority of them having a positive attitude toward it.
The key role of institution pressure on green supply chain practice and the firm's performance
Authors: Wongthongchai Jirawat , Saenchaiyathon Krittapha
Published: November 2019

Purpose: This study was conducted to investigate the influence of isomorphism institutional theory on green supply chain management (GSCM) and firm performance by using the structural equation model (SEM) to explain the driving factors of reducing the impact of environmental processes on the firm.Design/methodology/approach: Structural equation model (SEM) to explain the driving factors of reducing the impact of environmental processes on the firm.Findings: Isomorphism institutional factors showed a statistically significant positive effect on GSCM practices. Moreover, GSCM practices showed a statistically significant positive effect on firm performance. Under the literature review, customer pressure and top management support are primary factors to achieve GSCM practices and potential to establish firm performance.Research limitations/implications: First, the common hypothesizes do not provide insight into all the relationships that warrant additional inspection. Second, Thailand manufacturers have experiences pressures from foreign customers and competitors but they have opportunities to learn from them to better improvement GSCM practices.Practical implications: Results may highlight pressure for greening and which more efforts are needed for GSCM practices. GSCM practices generally require more effort due to need for collaborating with customer and competitor. Thailand manufacturers are increasingly confronted with isomorphism institutional pressure to implement GSCM practices.Social implications: It is useful the Thailand government promotes GSCM by creating an awareness of the benefits. GSCM can help to alleviate the question of the followers about implementing GSCM and decrease their risk association with the environmental adoption.Originality/value: Research creates clarity of the relationship between isomorphism institutional pressures, top management support, and performance in Thailand, which is a developing country with environmental investment concerns that affect profits from the operations of the firm.
Technology-Based Nursing Education: Overview and Call for Further Dialogue
Authors: Mallow Gail E , Gilje Fredricka
Published: November 2019

ABSTRACT

With the rapid growth of technology has come increasing reliance among health science disciplines to integrate technology into many courses. It is apparent that this reliance on technology in nursing education is increasing rapidly regardless of any guiding philosophy of education or pedagogy. The two-fold purpose of this article is to review the development of technology-based nursing education and to identify areas requiring further dialogue among nurse educators. It is becoming clear that nurse educators need to analyze values, communication, and social processes when deciding, judging, and assessing technological use within curricula. Nurse educators need to reflect on the tidal wave of change brought by technology and begin an earnest dialogue regarding its impact on the discipline.

Published: November 2019

Rapidly growing technological advances in big data, cloud computing, social media, artificial intelligence, virtual reality and digital media have led many educators to embark upon the pursuit and deployment of various digital tools in the classroom. They started implementing a technology-centered educational system in order to expand their pedagogical approaches and increase the possibilities of creatively putting ideas together and innovatively conveying their knowledge to their students. In this paper, we explore the convergence of creativity, technology, with art and design education, and we advocate the use of digital tools and repurposing of social media applications to support creative thinking. We discuss existing multimedia-based classroom practices that might encourage student creativity and suggest new forms and applications of technology aimed at providing the reflective teacher with more effective and efficient strategies to cultivate creativity while teaching art, design, and digital media courses.

Authors: Alameen Abdalla , Dhupia Bhawna
Published: November 2019

This paper deals with the necessary steps to be followed in upgrading the traditional e-Learning system to the new Adaptive e-Learning system. The framework, which is an important part of the implementation, is also covered in the paper. Before implementing the adaptive learning system, the existing system needs to be reviewed. A survey was conducted to find practical feedback from both the users: students and instructors to recognize their belief about the current e-Learning system. Results are discussed to frame the strategy to implement an adaptive learning system in which the issues of the current system can be addressed. To confirm the feedback, a report from the university LMS has also been taken into account and talked about. There are many open sources available in the market for the implementation of the adaptive e-learning. Along with the conceptual model, various popular LMS has also been discussed. A detailed comparison has also been exercised to identify their features. This paper can help the readers to derive all the components of a conceptual model for an adaptive e-Learning system and choose a suitable LMS for the actual implementation of the model.

Authors: Zhong Jinglei
Published: November 2019

Accounting vocational education directly bears on the competence of accountants, and affects the development of the accounting industry. In light of the back-ground of vocational education, this paper develops a competence model of ac-counting vocational education in China, applies the established model in an actual case, and puts forward measures to improve the competence of accounting voca-tional education. The research results show that: the evaluation index system of accounting vocational education should highlight importance, incentives and ef-fectiveness; the management and leadership ability is the primary factor of the competence of accounting vocational education; an excellent accounting vocation-al educator must enjoy outstanding management and leadership ability, account-ing ability and accounting skills; the competence of accounting vocational educa-tion should be improved mainly through incentive measures, from the perspective of adjusting the education purpose. The research findings lay the theoretical basis for self-evaluation, self-management and career planning of accounting vocational educators and accountants.
Tackling Nigeria's Image Crisis With the Aid of Popular Cinema
Authors: Endong Floribert Patrick C.
Published: November 2019

Knowing whether Nollywood filmmakers are conscious of their double role as Nigeria's image makers and cultural ambassadors has always been an interesting question to ask. However, only very few empirical studies have provided a forum for answering such a question. Most of the authors who have focused on Nollywood's contribution to the Nigerian image crisis have tended to dominantly relegate Nollywood filmmakers to capitalist “videastes” who are more driven by financial gains than by the desire to build or launder the image of Nigeria. This chapter censures this myopic tendency arguing that inasmuch as Nollywood filmmakers have be contributing to the Nigerian image crisis, a good number of Nigerian film directors and producers have, in their modus operandis sought to deconstruct the negative stereotypes of Nigeria in the international scene, thereby contributing to the rebranding of Nigeria. The chapter highlights a number of ways in which Nollywood filmmakers and the Nigerian government use cinema to deconstruct the negative image of Nigeria in the international scene.
Nollywood Video Films and the Nigerian Image Crisis
Authors: Udoh Anthony Paul , Etteyit Anietie Solomon
Published: November 2019

Mass media platforms, especially the video film, have been seen as potent tools for image construction or identity molding of any society. However, there are indications that the Nigerian movie industry has rather magnified the negative aspects of Nigeria, with the resultant image crisis for the country and its citizens. This chapter evaluates the role of Nollywood video films in the image crisis of Nigeria. Ten home videos were purposively selected from the collection of different producers. The findings show that the thematic characteristic styles of Nollywood are largely responsible for the image crisis of Nigeria and do more harm than good to its citizens. From the findings, it was recommended that script writers and movie producers in Nollywood should be alerted to the reality that their movies could negatively impact the image of the society, and should therefore make concerted efforts to mirror more of the positive aspects of the society and avoid creating image crisis for the country.
Development vs. Underdevelopment
Authors: Ibbi Andrew Ali
Published: November 2019

In recent times, the continent of Africa has been the darling of tourists all over the world. From various historical perspectives about the continent, curious people find the continent irresistible. However, a series of activities in the film industry both foreign and indigenous have suggested that the continent does not get a fair representation on the screens. How can film, a medium that has brought a lot of development to some countries of the world, not replicate the same in Africa? This chapter looked at the realities on the ground as far as representation of the continent is concerned, and discussed ways that could change the narrative for the better. It is a qualitative research that critically looked at the movie industries in Africa as well as other parts of the world.
“We Are Anything but a ‘Shithole' Country!”
Authors: Endong Floribert Patrick C. , Obi Paul
Published: November 2019

This chapter examines Nigerian online journalists' reception of Donald Trump's shithole remarks through a content analysis of 126 articles published online by 12 leading Nigerian newspapers, from January 2018 to January 2019. The chapter argues that Trump's shithole remarks engendered mitigated reactions from the Nigerian public, particularly from Nigerian online journalists. The greatest portion of these journalists' articles (over 68.73% of what they published online) hastened to endorse Trump's insult rhetoric and gloomy description of their country, presenting Trump's comment as a vivid depiction of the Nigerian socio-political and economic reality. In their articles, Nigerian journalists mainly used Trump's insult rhetoric as a tool to lambast the Nigerian leadership and lament the degradation of living conditions in their country. One thing that unfortunately remains evident and relatively deplorable in their reactions is the fact that little attention was given to the one-sidedness and exaggeration in Trump's comments. Based on such a premise, the journalists' endorsement of Trump's comments were in themselves one-sided and exaggerative, as they deliberately overlooked the positive facets of life in Nigeria and sounded as if Nigeria is all about negativities and doom.

Authors: Motornyuk Ruslan Leonidovich , Bilan Stepan Mykolayovych
Published: November 2019

Methods for image identification based on the Radon transform using hexagonal-coated cellular automata in the chapter are considered. A method and a mathematical model for the detection of moving objects based on hexagonal-coated cellular automata are described. The advantages of using hexagonal coverage for detecting moving objects in the image are shown. The technique of forming Radon projections for moving regions in the image, which is designed for a hexagonal-coated cellular automata, is described. The software and hardware implementation of the developed methods are presented. Based on the obtained results, a hexagonal-coated cellular automata was developed to identify images of objects based on the Radon transform. The Radon transform allowed to effectively extract the characteristic features of images with a large percentage of noise. Experimental analysis showed the advantages of the proposed methods of image processing and identification of moving objects.

Authors: Murugappan Mullai
Published: November 2019

The aim of this chapter is to impart the importance of domination in various real-life situations when indeterminacy occurs. Domination in graph theory plays an important role in modeling and optimization of computer and telecommunication networks, transportation networks, ad hoc networks and scheduling problems, molecular physics, etc. Also, there are many applications of domination in fuzzy and intuitionistic fuzzy sets for solving problems in vague situations. Domination in neutrosophic graph is introduced in this chapter for handling the situations in case of indeterminacy. Dominating set, minimal dominating set, independent dominating set, and domination number in neutrosophic graph are determined. Some definitions, characterization of independent dominating sets, and theorems of neutrosophic graph are also developed in this chapter.

Authors: A. Abd El-Ghany Hossam , Azmy Ahmed Mohamed , Saad Mohamed
Published: November 2019

The concept of distributed generation (DG) has been developed as a hopeful solution to meet the demand increase in distribution systems. The optimal DG deployment in the distribution system can improve the technical benefits. This study presents a framework to find the optimum location and size for different types of DG units to enhance the voltage stability index (VSI), improve the voltage regulation and reduce the daily energy losses. The emission effect and cost function (environment and economic benefits) are augmented in the multi-objective function. Combinations of DG types are introduced to obtain the best benefits from each one. The daily load variations and dynamic output of each DG type are considered in the problem formulation. The genetic algorithm (GA) technique is used to find the optimal allocation for different cases. The typical IEEE 33-bus system is utilized to evaluate the proposed framework.

Authors: Giwa Abdulwahab , Owolabi John Olusoji , Giwa Saidat Olanipekun
Published: November 2019

This study has been carried out to demonstrate the control of a reactive distillation process in which the production of biodiesel was taken as the case study using an advanced control method, which is known as dynamic matrix control. The control was accomplished by employing the transfer function model of the reactive distillation process developed, using the System Identification Toolbox of MATLAB, from the dynamic data generated when the prototype plant of the process was simulated with the aid of ChemCAD process simulator. The results obtained from the dynamic matrix control were compared with those of a proportional-integral-derivative (PID) control system tuned with Ziegler-Nichols and Cohen-Coon methods, and it was discovered that the dynamic matrix control was able to perform best among the three (dynamic matrix control method, PID tuned with Ziegler-Nichols method and PID tuned with Cohen-Coon method) because it (the dynamic matrix control) was able to make the biodiesel mole fraction response not to exceed the maximum limit value of 1 in addition to having the lowest sum of absolute errors (SAE) and sum of squared errors (SSE) from the control systems that were simulated.
Development and Performance Evaluation of a Novel Translational Tuned Mass Damper
Authors: Miah Mohammad Shamim , Miah Md. Jihad , Hossain Md. Ashik
Published: November 2019

The structures are prone to dynamic loads such as earthquake as they often generate uncomfortable movement into existing structures. In order to reduce extreme vibration generated by dynamic or operational loads passive, active or hybrid controlling devices are used. And the advantages of passive systems are well accepted due to their inexpensiveness and simplicity. This study investigates the performance of a newly developed uniaxial tuned mass damper (TMD). The novelty of the developed device is that the properties of the damper are adjustable based on the structural requirements. And most importantly, another key design criterion is to make a low-cost affordable device. To do this end, a toy two degree of freedom (2-DOF) system is considered and the experiments are conducted. The experimental tests and numerical simulations are carried out on the structure without and with TMD along with extra masses of 25 kg, 30 kg and 35 kg on the floors to observe the effect of floor mass changes. The scaled El Centro 1940 earthquake data is used as input excitation. In order to determine the optimal performance of the damper, it is tuned to modal mass of 0% (i.e., without TMD), 5%, 7.5%, 10%, 12.5%, and 17.5%. The experimental results have shown that the structure without TMD has pronounced vibration (i.e., displacement) as compared to the structure with TMD. As the percentage of modal mass increases, the vibration of the structure decreases. It is observed that up to 12.5% of modal mass for both 20 and 25 sec excitation duration could be the optimum amount that minimizes the vibration of the structure. The overall performance of this device is capable of reducing vibration in a reasonable manner and has the possibility to use it for the real engineering application.
Optimal AGC Design for Diverse Sources of Power Generations in each Area Using Output Vector Feedback Control Technique
Authors: Sharma Gulshan
Published: November 2019

In this paper an attempt is made to design the regulator for automatic generation control (AGC) of an interconnected energy delivery system to regulate the frequency and tie-power to original value for sudden change in the energy demand of the customers. The considered energy delivery system is having the power generation via thermal, hydro and gas sources and connected via means of parallel AC/DC tie-lines. Further, most of AGC studies focussed on regulator design using application of control theory such as optimal control to manage the balance between generation and load demand considering all system states. However, inreality it is hard enough to measure all system states and design effective regulator for AGC action. Hence in this paper efforts are made to design regulator for AGC problem using few states which are easily measurable and available in real situation of the system i.e. output vector feedback. The feasibility & stability of proposed AGC is tested for 1% change in power demand and compared with optimal AGC which is based on all system states using obtained system responses, feedback gains of control as well as closed loop eigenvalues.

In mice, the ability of naive T (TN) cells to mount an effector response correlates with TCR sensitivity for self-derived Ags, which can be quantified indirectly by measuring surface expression levels of CD5. Equivalent findings have not been reported previously in humans. We identified two discrete subsets of human CD8+ TN cells, defined by the absence or presence of the chemokine receptor CXCR3. The more abundant CXCR3+ TN cell subset displayed an effector-like transcriptional profile and expressed TCRs with physicochemical characteristics indicative of enhanced interactions with peptide–HLA class I Ags. Moreover, CXCR3+ TN cells frequently produced IL-2 and TNF in response to nonspecific activation directly ex vivo and differentiated readily into Ag-specific effector cells in vitro. Comparative analyses further revealed that human CXCR3+ TN cells were transcriptionally equivalent to murine CXCR3+ TN cells, which expressed high levels of CD5. These findings provide support for the notion that effector differentiation is shaped by heterogeneity in the preimmune repertoire of human CD8+ T cells.
Two Successive Inversional Vβ Rearrangements on a Single Tcrb Allele Can Contribute to the TCRβ Repertoire
Authors: Lee Kyutae D. , Bassing Craig H.
Published: November 2019

Mammalian TCRβ loci contain 30 Vβ gene segments upstream and in the same transcriptional orientation as two DJCβ clusters, and a downstream Vβ (TRBV31) in the opposite orientation. The textbook view is upstream Vβs rearrange only by deletion and TRBV31 rearranges only by inversion to create VβDJCβ genes. In this study, we show in mice that upstream Vβs recombine through inversion to the DJCβ2 cluster on alleles carrying a preassembled Trbv31-DJCβ1 gene. When this gene is in-frame, Trbv5 evades TCRβ-signaled feedback inhibition and recombines by inversion to the DJCβ2 cluster, creating αβ T cells that express assembled Trbv5-DJCβ2 genes. On alleles with an out-of-frame Trbv31-DJCβ1 gene, most upstream Vβs recombine at low levels and promote αβ T cell development, albeit with preferential expansion of Trbv1-DJβ2 rearrangements. Finally, we show wild-type Tcrb alleles produce mature αβ T cells that express upstream Vβ peptides in surface TCRs and carry Trbv31-DJβ2 rearrangements. Our study indicates two successive inversional Vβ-to-DJβ rearrangements on the same allele can contribute to the TCRβ repertoire.

Una cuestión de amor. Bios, biopolítica, bioseguridad

Published: November 2019

A partir de una experiencia personal (la muerte de un ser querido relacionada con el sida) y de un corpus de producciones artísticas que abordan la experiencia de vivir con VIH (de "vivir con virus", como marca un texto de Marta Dillon), en mi exposición plantearé una pregunta básica: ¿cómo pensamos hoy la vida? ¿Cuál es nuestra relación con lo vivo, con la bios? Esta exposición tendrá la forma de una galería de imágenes, una especie de álbum familiar extendido. El comentario de dichas imágenes (que incluyen los fotogramas de un documental, el registro de distintas piezas artísiticas, algunas fotografías de mi propio álbum familiar o los retratos de Michel Foucault, Luc Montagnier o Donna Haraway) articula y produce el discurso con el que me aproximaré a las respuestas que puede suscitar la pregunta de inicio: ¿cómo entendemos la vida hoy? ¿Qué efectos producen nuestras concepciones de lo vivo? ¿Qué formas de vida resultan o se ajustan a ellas? Más allá de la inercia que nos lleva a considerar al otro como a un extraño, un peligro, un objeto de consumo o un competidor, en mi presentación apuesto por nuestra capacidad para elegir una relación de riesgo, de confianza y de amor hacia las otras. Para ello, en cualquier caso, tendremos que pensar en los dispositivos (biopolíticos, biomédicos, securitarios) que dificultan o inhiben esta elección.
Los Horizontes Mestizos: Polílogos, simbología y permeabilidad política en el arte.
Authors: Martínez Bueno Juan Felipe
Published: November 2019

Ante el desgaste de los modelos políticos y democráticos, centrados en la discusión, el debate y los esquemas formales de representación y acción política proponemos el polílogo -acuñado por F. M. Wimmer para encarar asertivamente el contacto filosófico intercultural- y la simbología como corrección, oposición y ampliación de las dinámicas centralistas mono/dialógicas que, con sus respectivas estructuras demo-liberales, condicionan los contenidos y relaciones entre las partes involucradas en las disputas políticas. De este modo pretendemos elucidar algunas de las posibilidades de interacción multicultural  que proporciona la simbología, entendida brevemente aquí como la expresión ontológica y epistémica de los horizontes sociales. A diferencia de los escenarios estrictamente políticos, la simbología en su vertiente artística permite -e invita- al mestizaje de los horizontes debido a su capacidad reconciliadora de los opuestos (en este caso el yo/otro, centro/periferia, local/extranjero) abriendo camino a modelos alternativos de integración que ya no solamente operen desde la verticalidad institucional definida por un esquema y origen definidos dentro del pensamiento eurocéntrico, sino mediante la flexibilidad y permeabilidad que han caracterizado a los movimientos artísticos y sus dinámicas de frontera. La política del disenso, en clave simbolista, apunta al cuestionamiento de los modelos de participación cultural y hacia la efectiva apertura a un mestizaje ontológico y metodológico que, en su receptividad multidireccional de poli-logo, cuestiona incluso los valores promovidos por el liberalismo pan-económico, erigiéndose como un laboratorio artístico/político divergente y necesario ante el estancamiento de los paradigmas y, además, muy urgente ante la escalada de los populismos nacionalistas de Europa y el mundo.
FOTOGRAFÍA Y MEMORIA HISTÓRICA EN LA GENERACIÓN DE LA POSMEMORIA
Authors: Cáceres Sánchez Iván
Published: November 2019

En una realidad democrática cada vez más polarizada es necesario prestar atención a una de las cuestiones clave, fuente de polémica y desencuentro, como es la de la recuperación de la Memoria Histórica. Dentro de un proceso de renovación y redefinición de una democracia moderna, es imprescindible abordar el problema de la Memoria Histórica, especialmente en lo relativo a la Guerra Civil Española, poniendo en cuestión pasado y presente con una mirada crítica. Es aquí donde el arte y, en concreto, la fotografía tiene mucho que aportar. La práctica artística se constituye como espacio de reflexión y reivindicación totalmente integrado en un proceso de reforma democrática. Los fotógrafos y artistas que se valen de la fotografía actúan como agentes dinamizadores de este cambio de paradigma. En esta investigación pondremos el foco en artistas jóvenes actuales (nacidos a partir de los años 70) cuya obra habla directamente sobre la Guerra Civil Española o sobre aspectos derivados de ella, artistas pertenecientes a la “generación de la posmemoria”. Este concepto será clave para analizar la dialéctica presente en los trabajos de artistas nacidos después de la dictadura franquista.   La presente investigación consta de dos objetivos fundamentales: analizar el término posmemoria poniéndolo en relación con las propuestas fotográficas de artistas jóvenes relevantes y, por otra parte, dar visibilidad a estos trabajos con la intención de generar un mapa actualizado que hable sobre el estado de la cuestión de la Memoria Histórica en el ámbito de la fotografía contemporánea. Para ello se han trabajo, por una parte, textos de Marianne Hirsch, Clément Chéroux, James Young, Ernst Van Alphen, Beatriz Sarlo y Laia Quílez Esteve (entre otros), y por otra parte, se han analizado propuestas significativas de artistas como Eugenio Merino y varios de los artistas participantes en la exposición Monte de Estépar.   Algunos de las propuestas fotográficas contemporáneas más celebres en relación a la Guerra Civil Española proceden de autores nacidos entre los años 50 y 60, sin embargo cabe destacar que el número de artistas nacidos a partir de los 70 que tratan esta problemática es notablemente creciente, como consecuencia de un distanciamiento generacional con el acontecimiento y de una mayor presencia de esta discusión en los medios de comunicación. Sin duda, este hecho está contribuyendo a romper el voto de silencio y a normalizar este debate.

Todas las formas posible de fracaso aparecen ante nosotros cuando contemplamos con desasosiego el vértigo entre la figura del equilibrista y la del artista contemporáneo. Ambos agentes presentan, a parte de obvias realizaciones estéticas y formales en el desempeño de su destreza, algo que vas más allá de este simple vértigo: una actitud de riesgo perseverante que nos expone de forma rigurosamente explicita al abismo. Nuestro cuerpos asumen al límite su condición de espacio para la experimentación de este vértigo de inclinación ferozAsí, todo gesto creativo implica, en sentido estricto, una confrontación directa con el abismo: sea este el abismo de las múltiples formas en que nuestro trabajo puede transformarse, es decir, en la incertidumbre de las formas y en la aceptación de la performatividad autónoma de la materia, o mediante la exposición al abismo de nuestras ideas.Lo que nos apasiona de este paralelo ultrapasa, de forma desmedida, cualquier análisis formal de la imagen entre ambos para indagar cuestiones relacionadas con una especie de amenaza: la de la estabilidad en contraposición a la inestabilidad de la cuerda floja. El fracaso, la decepción, la ruina: ¿acaso no son estas ideas una constante presencia en un cuerpo de trabajo con vocación de éxito?. La expectativa del fracaso en el deambular de una cuerda floja, es igualmente proporcional al la posibilidad de un fracaso con éxito.Y en este punto es cuando podemos entonces asumir el fracaso como posicionamiento estético-político: como estado vibrante de revuelta contra la producción de un modelo de vida capitalista color de rosa, y hacia la invención del cotidiano como una forma de emancipación y de nuevas subjetividades adyacentes.Este ejercicio como forma de resistencia a la hiperactividad enunciada por el estilo de vida del emprendedor neoliberal, anuncia un nuevo paradigma de acción donde el riesgo a caer al vacío explorando sus límites, suponga asumir el fracaso como posibilidad de transformación.
Aldo van Eyck, una narración entre signos y dibujos. El Estec de Noordwijk
Authors: Ginex Gaetano
Published: November 2019

El trabajo aquí presentado trata la importancia del dibujo configurativo en la elaboración de la idea proyectual en arquitectura. Es un testimonio del método proyectual de Aldo van Eyck, que usa el dibujo como medio expresivo que concreta el pensamiento y lo ilustra a través de una arquetípica exploración de la forma. Además de un análisis de los dibujos, esta narración representa una reflexión sobre un método de trabajo, donde el gesto gráfico, visto como dimensión espacial del pensamiento, es la herramienta principal para modificar el existente. En los esbozos de van Eyck, pensamiento, palabra, lenguaje y expresión gráfica son una sola cosa dentro de un ámbito disciplinar lógico-poético. El dibujo se convierte en un complejo texto narrativo e ilustra la idea de Arquitectura de un gran Maestro de la Arquitectura.

 
Dibujo y control. El trabajo de Javier Carvajal para Loewe
Authors: Antón Sancho Javier , González Presencio Mariano
Published: November 2019

En 1959 la prestigiosa firma Loewe, decidió renovar su imagen y para su diseño eligió al arquitecto Javier Carvajal. Al enfrentarse a estas tiendas, Carvajal se encontró con que mucha parte de las estrategias que había desarrollado en sus proyectos anteriores se revelaba inhábil. Sin embargo, el arquitecto se enfrentó a estos encargos con la misma determinación de control formal que en sus anteriores proyectos; en un proceso de definición exhaustivo. Más allá de los planos generales de distribución, los interiores de la tienda, su mobiliario y detalles se dibujaron de la propia mano del arquitecto, a escala 1:1 las más de las veces, estableciendo con precisión las relaciones constructivas entre los distintos elementos y materiales. Todos los empalmes, los tornillos y fijaciones quedaron recogidos en unos dibujos sin concesiones, puras órdenes gráficas que compusieron una suerte de construcción virtual que pretendía reducir al máximo el margen de error.
Método de coordinación cartográfica en los estudios de la forma urbana. El caso de la avenida del Puerto de Valencia
Authors: Temes Córdovez Rafael R.
Published: November 2019

Los estudios sobre la evolución de la forma urbana recurren frecuentemente al uso de métodos de análisis en los que la representación gráfica, rigurosa y precisa, se revela como un medio óptimo en el proceso investigador para medir, comparar y valorar los cambios y trasformaciones experimentados. Es objeto de esta investigación, utilizando el eje de la avenida del Puerto en Valencia como modelo de estudio, demostrar la validez del método de coordinación cartográfica, en el que se verifican las relaciones entre las cartografías redibujadas de diferentes épocas, tomando como puntos de apoyo las permanencias o invariantes que aseguran la comparación a lo largo de la secuencia de estudio. Asimismo, se pretende también subrayar el potencial que ofrecen los Sistemas de Información Geográfica en los estudios de evolución urbana para los que la componente espacial constituye un dato primordial. El análisis se inicia en el siglo XVIII para centrarse con mayor detalle entre los años 1944 y 2004.
La representación del paisaje sonoro en el proceso de diseño arquitectónico
Authors: Llorca-Bofí Josep , Llorca-Bofí Vicent , Redondo Domínguez Ernest

La gestación de la idea o “insight” es una de las principales fases del proceso de diseño arquitectónico. A lo largo de la historia se han utilizado diversos métodos para abordar esta fase tan crucial. En este estudio se propone el paisaje sonoro como generador de ideas de proyecto. Para explorar este nuevo enfoque se ha realizado una experiencia docente en estudiantes de arquitectura y se han analizado los resultados tanto de satisfacción como de los diseños generados. Los resultados muestran la capacidad pedagógica del método, el impacto en la valoración subjetiva de los fenómenos del entorno arquitectónico y su aplicabilidad independientemente del nivel musical previo de los alumnos.
La geometría en los edificios de la Ciutat de les Arts i les Ciències de Valencia
Authors: Sanchis Sampedro Francisco Javier , Fernández Plazaola Igor
Published: November 2019

La importancia de la utilización de la geometría en el diseño de Arquitectura, y más en concreto el uso de las superficies geométricas como configuradoras del espacio arquitectónico, es el tema central del presente artículo. En él se pone en valor el uso de estas formas geométricas definidas como elemento de control formal en la fase de diseño de los edificios y que a su vez ayuda a mantener una coherencia con el comportamiento estructural y una mayor facilidad tanto en la ejecución como en la materialización constructiva. Se ha realizado un caso práctico de análisis formal geométrico, la “Ciutat de les Arts i les Ciències” de Valencia, que constituye uno de los ejemplos de aplicación más claros de las formas geométricas en la Arquitectura actual. Los análisis son fundamentalmente de generación de las superficies, pero también recogen la vertiente estructural y constructiva estudiada desde el punto de vista geométrico.
Efectos subjetivos de las políticas de emprendimiento entre la juventud española
Authors: Carbajo Padilla Diego , Santamaría López Elsa
Published: November 2019

En la última década, la Unión Europea ha implementado políticas de fomento del emprendimiento y el autoempleo destinadas a contrarrestar los perturbadores efectos de la crisis financiera mundial en el empleo juvenil. Partiendo de la pregunta de investigación sobre qué tipo de individuo buscan producir estas políticas de emprendimiento, se analiza los efectos subjetivos de estas políticas en la juventud española. Este análisis se fundamenta en un estudio cualitativo compuesto por la revisión documental de las políticas y un trabajo de campo exploratorio, a partir de observaciones participantes en eventos institucionales, grupos de discusión y entrevistas en profundidad a jóvenes involucrados en proyectos emprendedores. Entre los resultados se identifica una tensión central entre el discurso gubernamental sobre el emprendimiento y las experiencias de las personas entrevistadas, que viene a mostrar la articulación entre el emprendimiento y la precarización. Alineado con investigaciones críticas recientes en este campo, se concluye estableciendo que estas políticas implican una concepción de trabajo sobre uno mismo que lleva al actor social a normalizar y colaborar en su propia precarización.
“Sobre el futuro”: Discursos y prácticas laborales de estudiantes de liceos técnico-profesionales en tres claves de desigualdad
Authors: Rubilar Donoso Gabriela , Muñiz-Terra Leticia , Dominguez-Amoros Màrius
Published: November 2019

Este artículo analiza los discursos y prácticas laborales de un grupo de estudiantes que cursan los últimos años de enseñanza media en Chile. El análisis se realizó siguiendo las directrices del enfoque biográfico con especial énfasis en tres ejes o claves de desigualdad: las desigualdades socioeconómicas, de género, y las diferencias territoriales, al momento de imaginar trayectorias laborales futuras. La metodología seguida en esta investigación incluyó entrevistas biográficas sostenidas con estudiantes de tres liceos técnicos profesionales de la Región Metropolitana y el análisis se realizó utilizando la perspectiva biográfica comparada. Los resultados permiten dan cuenta de las visiones que estos jóvenes construyen respecto de su propia formación para el trabajo, los itinerarios educativos seguidos para este fin y sus proyecciones laborales futuras. Se incluye un análisis contextual sobre las trasformaciones en el mercado del trabajo y el modo como estos jóvenes observan este contexto, cuando lo entrecruzan con otras desigualdades relacionadas con el acceso al empleo, las remuneraciones futuras y los tipos de contratos a los que aspiran, que atraviesan sus propias definiciones en tanto jóvenes de "contextos vulnerables".
