Considering the Linkage Between the Theory of Trust and Classical Rural Sociology’s Concepts
Authors: Bodor Ákos , Grünhut Zoltán , Horeczki Réka
Published: November 2018

The paper presents a multi-theoretical argument by linking the mid-range concepts of risk and trust to some core, classical approaches of rural sociology. The main assumption is that risk and trust, two essential features of social interactions in late modernity are influenced by the rural and urban forms of coexistence. Based on the typological grand theories of early rural sociology, countryside-like milieu reduces risks, and by this, supports the individual abilities of showing trust. The paper analyzes this assumption on European countries’ data through a quantitative empirical inquiry. The findings do not strengthen the basic hypothesis which conclusion suggests that the classical typological approach of rural sociology should be seen through a critical lens – just as the new theoretical interpretations from the field recommend it.

Penelitian ini berfokus pada objektivitas perempuan tua dalam fotografi jurnalistik. Objektivikasi perempuan adalah objek yang menarik karena menjadi sebuah fenomena dalam kehidupan masyarakat. Hampir di setiap media massa, perempuan diposisikan sebagai pelengkap dunia laki-laki. Paras cantik dan keindahan lekuk tubuh perempuan dijadikan sebagai objek seksual. Lain halnya dalam karya fotografi pada pameran “Jalan Menuju Media Kreatif #8”. Dengan analisis deskriptif interpretif berparadigma kritis, penelitian ini bertujuan mendeskripsikan dan menginterpretasikan data yang bersangkutan dengan objektivikasi dan mitos dalam karya fotografi jurnalistik. Variabel penelitian ini adalah fotografi jurnalistik, perempuan, dan komunikasi visual. Terdapat tiga objektivikasi perempuan dalam karya foto jurnalistik ini: pertama, objektivikasi perempuan terletak pada inner beauty; kedua,; perempuan menikmati pekerjaannya sebagai ibu rumah; dan ketiga, perempuan tampil tanpa make up tebal. Mitos kecantikan perempuan terletak pada inner beauty, dalam foto-foto ini disajikan melalui keaslian wajah, profesi, dan ketaatannya. Mitos lain adalah penempatan perempuan yang selalu di wilayah domestik. Dengan demikian, perempuan tidak lagi hanya menghabiskan waktunya untuk berdandan dan bergaya. AbstractObjectification of Elderly Women in Photojournalism: Analysys of Semiotics on the Photographs of ‘Jalan Menuju Media Kreatif #8’. This study focused on elderly women objectivity in photojournalism. The objectification of women is an interesting object because it has become a phenomenon in the society. Almost in every mass media, women are positioned as the complement of men’s worlds. Pretty faces and the beauty of women’s curves are made as sexual objects. There was a difference in the photography exhibition in the event of “Jalan Menuju Media Kreatif #8”. By using interpretative descriptive analysis with critical paradigm, this research aims to describe and to interpret the data related to the objectification and myths in the photography works of photojournalism. The variables of this research are photojournalism, women, and visual communication. There are three objectifications of women in those works of photojournalism; first, objectification of women on their inner beauty; second, women enjoying their work as homemakers; and three, women without thick make-up. The myth of female beauty lies in the inner beauty,therefore in the photographs they were represented through the authenticity of their faces, professions, and obediences. Another myth is the position of women in the domestic sphere. Thus, women did not just spend their time to dress up and to be stylish.
THE USE OF HEDGING DEVICES IN APPLIED LINGUISTICS ACADEMIC DISCOURSE: THE CASE OF READING IN A FOREIGN LANGUAGE AND ENGLISH LANGUAGE TEACHING RESEARCH ARTICLES
Authors: Anh Nguyen Tuan
Published: November 2018

Hedging enables academic writers be able to mitigate claims and minimize the impositions that may be found in such claims (Hyland, 1996). Although the literature has had vast research on hedging in research articles, not much has been known about the difference or similarity among journals in one field in the use of hedging devices. Using the document analysis method, the present study aims to make a comparative analysis of hedging in two linguistics research journals, namely Reading in a Foreign Language (RFL) and English Language Teaching (ELT), in order to investigate what hedging forms and functions are most frequently used in RFL and ELT, and how hedging forms and functions are distributed in the Introduction, Results, Discussions and Conclusions sections in the two journals. Based on the data analyzed, it was found that RFL and ELT research article writers tend to have the same preference for the use of different hedging forms for different equivalent purposes and functions. This similar hedging pattern is believed to be of value to those who are trained as academic writers in the field of linguistics.
THE TRANSITION TO ENGLISH TEACHING: INFLUENCES AND CONSIDERATIONS FOR FOREIGN LANGUAGE EDUCATION AND LANGUAGE PLANNING
Authors: Hao Tran Thi
Published: November 2018

Language policy enactment processes are complex, confounded by varied forces and interests, and shaped through negotiations, interpretations and compromise. Working from this perspective, this article examines the transition process of foreign language teachers from teaching other languages to teaching English, and the influences of this process on general foreign language education and language planning. In Vietnam, even though the shift to English teaching from other languages has been noted as a phenomenon, its process with grass-roots changes and potential influences on foreign language policy enactments in the country have not been specifically examined. By employing a case study approach, this article explores the transition process at An Nam University (pseudonym), one of the universities undergoing the transition process. Drawn from a document, a preliminary survey, interviews with both teachers and leaders and observations, my study concludes that the transition process has an important role with various influences on different aspects in foreign language education in the university and in Vietnam. The study aims to provide fundamental pointers to current language policy implementation in the country as well as to other contexts undergoing similar changes.

Authors: Chan Shun-Chiao , Wang Yi-Chih , Hong Che-Wun
Published: November 2018

This research employs the first principles computation to simulate the chlorine (Cl) doping effect with different proportion (x value) on the photovoltaic and thermoelectric properties of bulk mixed halide methyl-ammonium lead perovskites (MAPbI3-xClx). In the study, the density functional theory (DFT) and Boltzmann transport equation (BTE) are applied to calculate the optical band gaps, electrical conductivity , carrier thermal conductivity , and Seebeck coefficient S. The density functional perturbation theory (DFPT) and Debye model are used to calculate the phonon thermal conductivity . Tuning the greatest thermoelectric figure of merit (ZT) with suitable solar absorbance range is the major target for our solar thermoelectric chip design. The simulation results reveal that doping Cl will increase the electronic conductivity, phonon thermal conductivity, and causes a blue shift in the light absorption. The main contribution to the total thermal conductivity is mainly from optical phonons, and the main absorbance wavelength locates in the ultraviolet and visible light region (40nm <  < 700nm). When x=0.25, MAPbI2.75Cl0.25 achieves the optimized tuning for both light absorption coefficient α and figure of merit ZT in our simulation cases.

Published: November 2018

This paper reports an experimental work to investigate the pit corrosion of steel bars in chloride contaminated concrete. A total of 50 reinforcing steel bars with a length of 250 mm and a diameter of 14 mm were embedded in 10 concrete specimens, before they were subjected to accelerated corrosion. The geometric parameters of the corroded steel bars were then examined using 3D scanning method, before the characteristics of pitting corrosion of the corroded bars were analyzed accordingly. The results show that there is a weak correlation between the maximum pit depth and the mass loss rate. However, there is a strong correlation between the pitting factor and the mass loss rate. The relationship between the pitting factor and the mass loss rate has been developed as a reciprocal function.

Authors: Srivastava Divya , B. Rajitha , Agarwal Suneeta
Published: November 2018

Diseases in leaves can cause the significant reduction in both quality and quantity of agricultural production. If early and accurate detection of disease/diseases in leaves can be automated, then the proper remedy can be taken timely. A simple and computationally efficient approach is presented in this paper for disease/diseases detection on leaves. Only detecting the disease is not beneficial without knowing the stage of disease thus the paper also determine the stage of disease/diseases by quantizing the affected of the leaves by using digital image processing and machine learning. Though there exists a variety of diseases on leaves, but the bacterial and fungal spots (Early Scorch, Late Scorch, and Leaf Spot) are the most prominent diseases found on leaves. Keeping this in mind the paper deals with the detection of Bacterial Blight and Fungal Spot both at an early stage (Early Scorch) and late stage (Late Scorch) on the variety of leaves. The proposed approach is divided into two phases, in the first phase, it identifies one or more disease/diseases existing on leaves. In the second phase, amount of area affected by the disease/diseases is calculated. The experimental results obtained showed 97% accuracy using the proposed approach.

A novel cohesive zone model to simulate ductile adhesives in automotive structure metallic joints
Authors: Googarchin Hamed Saeidi , Shojaeefard Mohammad Hassan , Gheibi Mohammad Reza , Sarvi Zohreh
Published: November 2018

In recent years, increasing utilize of the adhesively bonded joints due to its prominent features in distribution of the stress in bonded area and bonding dissimilar material has led to developing its computational aspects to provide more reliable response. In this regard, cohesive zone model (CZM) as an effective method to simulate bondline is introduced. The crucial aspect of this method is the determination of the relation between traction and separation in fracture process zone (FPZ). In fact, the traction-separation law (TSL) is a material model which must be properly obtained and applied to the adhesive bondline. According to the literature, mechanical response of the adhesive joints in most cases (especially in ductile and semi-brittle adhesives) is depended on the TSL curve shape. In this study, a novel CZM is developed to simulate double cantilever beam (DCB) adhesive joint. The main advantageous this new model is considering non-linear behavior of ductile adhesives in elastic region. DCB coupons fabricated by means of Al 6061 adherends and Araldite 2015 adhesive. After direct extraction of the TSL and obtaining cohesive parameters of the new model, numerical simulation of the DCB is conducted. Finally, sensitivity analysis of cohesive parameters and effect of initial crack length on the DCB response is investigated.

Published: November 2018

This research focuses on studying the dynamic energy absorption property of a micro-alloyed TWIP steel, which was proposed to act as a connection part between car front bumper and chassis in middle-class cars for vehicle safety. The studied TWIP steel was designed based on stacking fault energy of 25mJ/m2. The as-cast steel was deformed in hot and cold rolling to 2 mm thick sheets. Subsequently, recrystallization annealing was applied to the heavily cold-worked steel at different temperatures to obtain different ultrafine grain structures. The mechanical properties were determined using tensile tests. It was observed that at 900°C, the optimal temperature for strengthening by vanadium carbide precipitation, it was too low to complete recrystallization. However, at 1000°C, an ultrafine-grained structure was formed with high yield, tensile strengths and elongation of about 700MPa, 1100MPa and 30% respectively. Accordingly, TWIP steel was used for crash analysis simulation using ANSYS Workbench R14.5. Thin-walled square columns of that steel were employed for energy absorbance during a collision regarding progressive plastic deformation. The crashworthiness criteria were studied under different impact conditions with thicknesses of 0.25, 0.5, 0.75 and 1 mm. Simulation results showed high initial peak force during the impact. Hence, a trigger mechanism of an external tapered plunger was proposed to reduce it. This combination of new material and innovative design promises enhancement car safety.

Noticias telúricas: el “temblor grande” de 1822 a través de la prensa chilena y extranjera

Pestes, inundaciones, sequías y terremotos; estos y otros fenómenos, provocados por los riesgos naturales, han acompañado la formación y los distintos procesos históricos de Chile como reino y nación. Aquella tierra “mal infamada” de la que hablaban los primeros conquistadores y cronistas siempre estuvo ligada en alguna dimensión con lo catastrófico, como un devenir infausto que, en palabras de Rolando Mellafe, generó un carácter telúrico en su población. A inicios del siglo XIX, la formación de la república y el Estado independiente también convivieron con eventos naturales, cuyas consecuencias fueron determinadas por el contexto que se vivía en la época, siendo el terremoto del 19 de noviembre de 1822 uno de los más paradigmáticos, tanto por sus efectos como por la compleja trama de la cual terminó siendo parte.

Demographic consequences of native fox predation on Socotra cormorants on Siniya Island, United Arab Emirates

Predation by both native and introduced terrestrial predators is a major threat to colonially breeding seabirds leading to low breeding success and negative demographic effects. The Socotra cormorant Phalacrocorax nigrogularis is a regionally endemic seabird categorized as Vulnerable by the IUCN. It breeds on islands in the southern Arabian Gulf and in the Gulf of Oman. One colony, Siniya Island, on the northern United Arab Emirates hosts about 40% of the global breeding population. Socotra cormorants are ground nesters and are vulnerable to predation by native Arabian red foxes Vulpes vulpes arabica, occuring naturally on Siniya island. We used camera trapping to estimate the population size and diet composition of foxes on the island. A total of 24 foxes were identified including adults and cubs, and cormorants and their eggs dominated the fox's diet (80%) during the breeding season. We estimated that the foxes killed >3500 cormorants during the season. The cormorant population was modelled using Vortex. The simulated population increased from 46 500 individuals (corresponding to the known population in 1995) to stabilize between 154 000 and 188 000 birds after 2010 in the absence of mortality from predation. Simulated mortality showed various degrees of population suppression and increasing extinction probabilities at higher degrees of predation. The model was more sensitive to predation of adult birds. Predation rates causing up to 35% juvenile mortality stabilized at <250 000 birds. Contrastingly, adult mortality of >25% caused the population to stabilize at <80 000 birds. Actual population estimates from 2011–2015 ranged from 79 000–124 000 birds. Thus, our model suggested that the cormorant population was suppressed due to predation at levels consistent with 20–25% adult mortality in the simulated population. Continual monitoring of the impact of foxes is essential and management of foxes may be recommended as a conservation measure if predation pressure increased.
