KUPU-KUPU DI ATAS BUNGA – ANGIN MENARI MELALUI PADANG: MENYIMAK FILSAFAT SENI MARTIN HEIDEGGER
Authors: Runesi Yasintus T.
Published: October 2019

In his path of thinking, particularly from the 1930s onwards, Martin Heidegger firmly believed that Sein reveals itself, when human being, whom he termed as Dasein, awakened from his blindness of common sense and struggle for grasps his own authenticity. In this paper I examine Heidegger’s destruction of the work of art as a site of strife between art and politics in his text, Der Ursprung des Kunstwerkes. Heidegger’s position is complex: on the one hand, he acknowledges that Sein is a phenomenon beyond our horizon of understanding, Sein is all about not something particular; on the other hand, he insists that Sein’s presence through art inscribed in a certain particular identity, especially German volks. In response, I argue that the identification of Sein with a particular identity such as German volks, offers the truth that the politics itself is forged and instituted in and as work of art. Some conclusions will be drawn concerning the importance of the small dimension of Heidegger’s thought on art in contemporary politics.
BUNUK: PENGETAHUAN DAN PRAKTEK ATONI-METO DALAM TATA KELOLA HUTAN
Authors: Usbobo Yohanes Victor Lasi
Published: October 2019

The implementation of todays forest management that based on formal-scientific knowledge and technical knowledge seems to fail to protect the forest from deforestation and the environmental damage. Decolonialisation of western knowledge could give an opportunity to identify and find the knowledge and practices of indigenous people in sustainable forest management. Forest management based on the indigenous knowledge and practices is believed easy to be accepted by the indigenous community due to the knowledge and practice is known and ‘lived’ by them. The Atoni Pah Meto from West Timor has their own customary law in forest management that is knows as Bunuk. In the installation of Bunuk, there is a concencus among the community members to protect and preserve the forest through the vow to the supreme one, the ruler of the earth and the ancestors, thus, bunuk is becoming a le’u (sacred). Thus, the Atoni Meto will not break the bunuk due to the secredness. Adapting the bunuk to the modern forest management in the Atoni Meto areas could be one of the best options in protecting and preserving the forest.
Developing lure and kill systems for thrips pest management
Authors: Kean A.M. , Nielsen M-C. , Davidson M.M. , London H.
Published: October 2019

Some thrips species (Thysanoptera) are important pests of crops in New Zealand and are vectors of several important plant tospoviruses Lure and kill could provide an alternative or complementary control to the current practice that relies on the unsustainable use of insecticides The efficacy of a lure and kill device was tested on thrips in a grass field The thrips olfactory lure used was methyl isonicotinate the visual cue was yellow and the kill component in the trap was an organophosphate insecticide applied to an absorbent material The control device was yellow but did not contain the lure or insecticide The device allowed thrips to freely enter and leave but limited the access of nontarget organisms The devices were left out for three days The ratio of dead thrips in the control devices relative to those with insecticide was 1344 Addition of the olfactory lure to the insecticide devices increased the ratio to 1475 The results highlight the need for an effective olfactory lure component to ensure the insects enter and explore the trap to be exposed to a lethal dose of the kill component Results are discussed in relation to thrips pest management

Published: October 2019

Objective: To comprehend every day of older people with venous insufficiency, who use elastic compression socks. Methods: Phenomenological research that interviewed 13 elderly attended Basic Health Units in the state of Minas Gerais, between November 2017 to January 2018. The depositions were organized in categories and discussed according to the Alfred Schütz social phenomenology and theme literature. Results: Emerged from the interviews that make explicit the perspective of the participants regarding their everyday activities with compression elastic socks: “main symptoms of the venous insufficiency relieved”, “adversities that permeate the use of elastic compression socks” and “long term use of compression elastic socks”. Conclusion: For elderly people with chronic venous insufficiency, the use of elastic compression socks promotes relieve of the symptoms; however, it demands help to put them on and take them off and provokes heat sensation and discomfort in the limbs. The elderly showed the expectation to continue the long term use of the elastic sock aiming at avoiding the relapse of varicose ulcer. To validate the adversities related to the use of this compression device may help the elderly to broaden their autonomy and functional capacity, which may be compromised by venous insufficiency.

Bases de hormigón para postes de madera
Authors: Sosa Jorge Omar
Published: October 2019

Por ser los postes material orgánico, en su interacción con el suelo origina un proceso de descomposición en la madera por agentes biológicos. La mayoría de los cuales son hongos xilófagos que alteran la celulosa y lignina o ambos a la vez por la acción de diversas enzimas que segregan pudiendo producir la desintegración de las paredes celulares. en realidad los procesos se desarrollan con distintas velocidades en la zona donde se combinan materia orgánica(suelo), humedad y aire. es aquí donde notamos que se crea un óvalo de descomposición que afecta al soporte, en mas o menos 30/35cm por encima y por debajo del nivel de suelo.

Articulación entre universidad y nivel secundario: herramientas psicosociales para el desarrollo de competencias académicas acerca de una experiencia en la ciudad de Posadas
Authors: Mendoza Rosana , Maggi Laura
Published: October 2019

La temática central aborda la problemática que supone el pasaje del ámbito escolar al universitario, constituyéndose, muchas veces en un obstáculo que los jóvenes no logran sortear. Pensar esta temática en términos de articulación reconfigura la relación entre niveles educativos, que hasta el momento se han mantenido alejados y fragmentarios en su desarrollo. Metodológicamente las actividades y producciones de esta extensión son abordadas desde un enfoque mixto cuali cuanti tativo, enmarcándose dentro de la perspectiva de suponer a la extensión universitaria como una intervención con finalidad de modificar o afectar la realidad social en el que se lleva a cabo. en base a ello se ha podido reconocer una serie de situaciones en docentes y alumnos que dificultan no sólo la circulación de los saberes sino que además acrecienta el distanciamiento en términos de representación de realidad entre ambas generaciones.

Actualmente, nos encontramos desarrollando capacitaciones docentes y alumnos destinadas a reflexionar acerca de las condiciones materiales en el cual se asienta el proceso de enseñanza/aprendizaje, y el modo en el cual ellos se implican (o no) en el mismo.

Published: October 2019

El grupo en energías renovables instaló un sistema fotovoltaico conectado a red (SFCR) en el predio del edificio del Departamento de Ingeniería en el campus Deodoro roca. El mismo se encuentra acoplado arquitectónicamente al camino de ingreso mediante una estructura tipo pérgola. El sistema posee una capacidad de generación de 6720 wp y cuenta con un total de 28 módulos fotovoltaicos (FV) de 240 wp cada uno. Los primeros resultados, obtenidos para un día claro en época invernal, muestran un total de 40 kwh de energía diaria disponible en caso de estar los generadores orientados en la dirección e inclinación óptima. Debido al acoplamiento arquitectónico solo están disponibles 32,25 kwh de los cuales, por efectos de sombras sobre los generadores, solo 28,52 kwh son inyectados a la red de baja tensión del edificio. En consecuencia, teniendo en cuenta la energía total disponible, la capacidad de generación del SFCR instalado se ve disminuida en un 28,7 %, de los cuales 19,5 % se debe a la orientación e inclinación del generador FV y 9,2 % a la proyección de sombras por parte del edificio adyacente.

Les mouvements sociaux et la transition progressiste sous un régime autoritaire
Authors: Vuong Thu-Trang
Published: October 2019

Ce travail s’inspire du développement de la communauté LGBT+ au Vietnam des années récentes, plus précisément depuis la création de l’organisation VietPride et la première marche Pride à Hanoi en 2012. Après 7 ans, les marches Pride annuelles ont lieu dans de plus en plus de provinces vietnamiennes (37 provinces, au moment de l’écriture de ce texte). Si le développement de ces mouvements visant l’égalité et conformité au respect des droits de l’Homme a vu un essor à la fois en échelle et en quantité, les événements organisés par VietPride ont également suscité des réactions de plus en plus drastiques des groupes de tendances conservatrices dans la société. On observe ainsi la formation des ailes politiques, quoique uniquement sur des enjeux sociaux, dans une société jusque-là peu politisée.
AN EFFICIENT LATTICE ALGORITHM FOR THE LIBOR MARKET MODEL
Authors: Xiao Tim
Published: October 2019

The LIBOR Market Model has become one of the most popular models for pricing interest rate products. It is commonly believed that Monte-Carlo simulation is the only viable method available for the LIBOR Market Model. In this article, however, we propose a lattice approach to price interest rate products within the LIBOR Market Model by introducing a shifted forward measure and several novel fast drift approximation methods. This model should achieve the best performance without losing much accuracy. Moreover, the calibration is almost automatic and it is simple and easy to implement. Adding this model to the valuation toolkit is actually quite useful; especially for risk management or in the case there is a need for a quick turnaround.
A Simple and Precise Method for Pricing Convertible Bond with Credit Risk
Authors: Xiao Tim
Published: October 2019

This paper presents a new model for valuing hybrid defaultable financial instruments, such as, convertible bonds. In contrast to previous studies, the model relies on the probability distribution of a default jump rather than the default jump itself, as the default jump is usually inaccessible. As such, the model can back out the market prices of convertible bonds. A prevailing belief in the market is that convertible arbitrage is mainly due to convertible underpricing. Empirically, however, we do not find evidence supporting the underpricing hypothesis. Instead, we find that convertibles have relatively large positive gammas. As a typical convertible arbitrage strategy employs delta-neutral hedging, a large positive gamma can make the portfolio highly profitable, especially for a large movement in the underlying stock price.
Is the Jump-Diffusion Model a Good Solution for Credit Risk Modeling? The Case of Convertible Bonds
Authors: Xiao Tim
Published: October 2019

This paper argues that the reduced-form jump diffusion model may not be appropriate for credit risk modeling. To correctly value hybrid defaultable financial instruments, e.g., convertible bonds, we present a new framework that relies on the probability distribution of a default jump rather than the default jump itself, as the default jump is usually inaccessible. As such, the model can back out the market prices of convertible bonds. A prevailing belief in the market is that convertible arbitrage is mainly due to convertible underpricing. Empirically, however, we do not find evidence supporting the underpricing hypothesis. Instead, we find that convertibles have relatively large positive gammas. As a typical convertible arbitrage strategy employs delta-neutral hedging, a large positive gamma can make the portfolio highly profitable, especially for a large movement in the underlying stock price.
Pentingnya Materi Lingkungan dalam Pembelajaran Bahasa Indonesia

Di seluruh dunia semua orang menghadapi masalah lingkungan. Masalah ini disebabkan oleh ulah tangan manusia itu sendiri yang secara sengaja merusak alam disekitarnya. Kerusakan lingkungan ini akan menghasilkan krisis ekologis yang menyebabkan masalah pada sumber daya alam, iklim, polusi dan lain sebagainya. Berbagai metode telah diusahakan agar dapat mengurangi kerusakan lingkungan ini, seperti kebijakan pemerintah yang melarang penebangan pohon secara ilegal, gerakan pecinta alam, dan masih banyak lagi usaha yang sudah dilakukan untuk mengurangi kerusakan lingkungan. Namun, metode tersebut tidak membuahkan hasil.
Perilaku Biaya Aktivitas
Authors: Wati Enny
Published: October 2019

Perilaku biaya adalah Cara biaya berubah dalam hubungannya dengan perubahan penggunaan aktivitas, apakah biaya berubah seiring dengan perubahan output yang terbagi dalam biaya variabel dan biaya tetap. Biaya Variabel adalah biaya yang jumlah keseluruhannya bervariasi secara proporsional terhadap perubahan keluaran. Biaya variabel Secara total naik ketika keluaran naik dan secara total turun ketika keluaran turunSedangkan Biaya Tetap adalah biaya yang dalam jumlah keseluruhannya tetap konstan dalam rentang yang relevan ketika tingkat keluaran aktivitas berubah. Biaya tetap dapat berubah tetapi perubahan ini tidak bergantung pada perubahan keluaran

Involvement of the cortico-basal ganglia-thalamo-cortical loop in developmental stuttering.
Authors: Chang Soo-Eun , Guenther Frank H H
Published: October 2019

Stuttering is a complex neurodevelopmental disorder that has to date eluded a clear explication of its pathophysiological bases. In this review, we utilize the Directions Into Velocities of Articulators (DIVA) neurocomputational modeling framework to mechanistically interpret relevant findings from the behavioral and neurological literatures on stuttering. Within this theoretical framework, we propose that the primary impairment underlying stuttering behavior is malfunction in the cortico-basal ganglia-thalamocortical (hereafter, cortico-BG) loop that is responsible for initiating speech motor programs. This theoretical perspective predicts three possible loci of impaired neural processing within the cortico-BG loop that could lead to stuttering behaviors: impairment within the basal ganglia proper, impairment of axonal projections between cerebral cortex, basal ganglia, and thalamus, and impairment in cortical processing. These theoretical perspectives are presented in detail, followed by a review of empirical data that make reference to these three possibilities. We also highlight any differences that are present in the literature based on examining adults versus children, which give important insights into potential core deficits associated with stuttering versus compensatory changes that occur in the brain as a result of having stuttered for many years in the case of adults who stutter. We conclude with outstanding questions in the field and promising areas for future studies that have the potential to further advance mechanistic understanding of neural deficits underlying persistent developmental stuttering.
Preschoolers’ recognition of and inferences from observed imitation
Authors: Afshordi Narges , Carey Susan
Published: October 2019

Six experiments explored the apparent discontinuity between infants’ success at inferring affiliation from observed imitation (Powell & Spelke, 2018), and 4-year-olds’ failure on the same inference (Over & Carpenter, 2015). We first tested whether children younger than age 4 (i.e., 3-year-olds) have an explicit, verbalizable, concept of imitation. Three-year-olds observed acts of imitation and could identify the copier (Exp. 1) and who the copier was “copying” (Exp. 2), thus demonstrating a lexicalized concept of imitation. Adults spontaneously inferred that the copier’s affiliation lies with the model over the non-model and that she will continue to copy the same model in the future (Exp. 3), but even five-year-olds failed at these two inferences and preschoolers showed no improvement from ages three to five (Exp. 4). However, preschoolers succeeded at making correct inferences when we primed the concept of imitation either lexically by use of the word “copy” (Exps. 2 and 6), or non-lexically by drawing attention to the fact that the copier had done something “like” one of the models (Exps. 5 and 6). Taken together, the findings provide evidence of continuity between the representations of imitation from infancy through the preschool years to adulthood. In the context of the present experiments, however, young children do not always spontaneously encode the central character's preferential imitation of one model over another.
Relationship between Quality of Life and Quality of Work life in a Small Island Destination: Millennial Employees’ Perspective
Authors: Naidoo Perunjodi , Munhurrun Prabha Ramseook , Deegumbur Pallavi
Published: October 2019

The topic of Quality of Life (QoL) has received increased research attention in recent research years as tourism development should contribute to the wellbeing of destination communities and those who are employed by the tourism industry. The consideration of younger employees that is the millennial work force is important globally but also for Small Island developing states with challenges of small population size and migration of the younger generation seeking better job opportunities abroad. To be prepared for the future, the tourism sector needs to understand and adapt to this younger workforce and investigate how they perceive their Quality of Work Life (QWL) and its impacts on their well-being. Examining how tourism contributes to QoL is important to better plan for tourism so as to support the prosperity of the population, industry and destination. Nevertheless, limited research has investigated QWL and QoL. The objectives of this study are to firstly examine the impact of QWL and QoL; secondly, to investigate the relationship between QWL and support for future tourism development and thirdly to examine the relationship between QoL and support for future tourism development. A mixed method approach with unstructured interviews and 400 questionnaires were used to investigate the issue. This study found that a relationship exists between QWL, QoL and support for tourism amongst millennial, and that age of the employees influenced this correlation.
Contested Interpretation of Vietnam War Heritage: Tour Guides’ Mediating Roles
Authors: Ngo Phuong M. , Bui Huong T.
Published: October 2019

The legacy of the Vietnam War associates Vietnam with being a destination for dark tourism. Located in the central Vietnam, Quang Tri, the former Demilitarized Zone (DMZ) has high density of historical sites left from the Vietnam War. Visitation to the war-related sites for commemoration and secular pilgrimage is among the top motivations for tourists arriving in the city. The current research seeks to investigate the mediating roles of on-site guides at the historical sites of Quang Tri. By observing on-site tour guide performance, analysing their narratives and conducting interviews with guides working at monuments and historical sites, and reflection of tourists visiting the sites, the authors provide a unique perspective of guiding at contested war heritage, where on-site guides perform multiple mediating roles. The findings of the study highlight the need to reappraise the role of on-site guides and have implications for the planning and development of guiding services at historic sites.
