Postmodern Feminist Perspectives in Eat Pray Love
Authors: Basotia Surabhi , Kothari Arpit
Published: December 2020

Postmodern Feminism is the epitome of two massive movements, Postmodernism and Feminism, in literature. It inculcates the features of Postmodernism into Feminism, hence urging feminism to confront and reconstruct its framework. Elizabeth Gilbert’s memoir, Eat Pray Love: One Woman’s Search for Everything across Italy, India, and Indonesia (2006), deserves scholarly attention as it allows us to apply the notions of the theory on the text and analyze it in the light of the theory. This paper evaluates the points of similarities and/or differences found during the discourse analysis of the chosen text with a focused emphasis on the aspects of ‘Non-Essentialism’, ‘De/Reconstructing the Female Self’, and ‘Breaking free from the boundaries of cliché Feminism’. The study reveals results which satiate the expectations of a Postmodern Feminist in the form of the protagonist, Elizabeth Gilbert. Gilbert breaks free from her ‘Essential’ mundane life and embarks on her inward and outward journey of self-discovery and in the process Deconstructs and Reconstructs one’s own self.

Published: December 2020

Anchored on the greater premise that students have preconceived ideas of qualities and characteristics of a good language teacher, this study investigates language teacher preferences of freshmen Thai learners and its implications to the development of teacher orientation programs. For this purpose, diaries of Thai learners enrolled in an intensive English program (IEP) were subjected to content analysis using explorative design to be able to formulate new category systems inductively. The result revealed seven major theoretical constructs that summed up the qualities expected by Thai learners from their language teachers: language proficiency, organization and communication skills, character and personality, pedagogical knowledge, socio-affective skills, IT/ICT skills, and cultural competence. On the other hand, an interview regarding the present teacher orientation program among 3 new teachers for the IEP course revealed that the present system was fairly addressing the concerns of the students with its limited topic, activity, and participation of teaching staff.

This study examines women barriers and empowerment opportunities in Yakurr Local Government Area of Cross River State, Nigeria. The study design was exploratory using quantitative and qualitative data. Data is obtained from 660 women from Yakurr Local Government Area of Cross River State. The research used a multi-stage sampling technique. Data was analyzed using descriptive statistics such as percentages and frequency tables, while the Chi-square was used to test the significance of relationship between the two hypotheses stated. The findings of the study revealed that 58.3% of the respondents’ report that they were aware of the availability of women empowerment programmes in their community. While, 31.9% of the respondents reported the provision of agricultural facilities as the widely available empowerment programme for women, 38.4% indicated that non-governmental organizations were the major benefactors of women empowerment programmes. The findings of the study further showed that 39.5% of the respondents acknowledged that they had benefitted from women empowerment programmes. Equality for all can be achieved when women are allowed to make their own decisions on issues that concern them and act on those opportunities without fear.

Published: December 2020

Eating out among older adults are becoming the norm due to its convenience and potential for social interaction. Malaysia is expected to become an aged nation whereby 14% or more of its population will be 65 years and older by 2050. Very little is known about restaurant preferences and patronage behaviours of older adults in Malaysia even though there had been numerous researches done involving this population. It is important to acknowledge this age group not just because they are living longer; but also, because they are getting bigger in size and economic power. The purpose of this study is to determine the factors influencing Malaysian older or silver consumers’ restaurant dining choices. Semi-structured in-depth interviews were done with Malaysian older people ages 55 and above. The interviews were recorded, transcribed and analysed. Atlas.ti software (version 7) was used to complement researchers’ analyses of interview transcripts and develop a visual representation of qualitative data. Major thematic categories identified by older consumers in this study included food, service, and location. Data are visually mapped and relationships between different themes are presented. This study will be beneficial in providing more insights to restaurateurs in Malaysia to better meet silver consumer needs.
An Empirical Evidence of Amanah Ikhtiar Malaysia (AIM) Microcredit Programme Participants’ Quality of Life
Authors: Isa Zuraidah Mohamed
Published: December 2020

Since the inception of microcredit programmes, various studies have been carried out to assess their impacts. Earlier studies seemed to highlight this on the participants’ income and consequently poverty. However, recent impact studies of microcredit programmes have been looking into participants’ quality of life. Thus, this study attempted to investigate the impact of Amanah Ikhtiar Malaysia’s microcredit programme on the participants’ quality of life and analyse the differences between the new and old participants. This study took on a different perspective by examining aspects of personal attitude, subjective norm, perceived behavioural control, as well as entrepreneurial intention and behaviour. In selecting the samples, a probability sampling (disproportionate stratified) technique was employed. The hypotheses were tested using cross-sectional data of 638 Amanah Ikhtiar Malaysia participants. The findings of the study showed that all the hypotheses were significant and supported, where there was significant influence between participants’ personal attitude and entrepreneurial intention, participants’ subjective norm and entrepreneurial intention, participants’ perceived behavioural control and entrepreneurial intention, participants’ perceived behavioural control and entrepreneurial behaviour, participants’ entrepreneurial intention and entrepreneurial behaviour, including participants’ entrepreneurial behaviour and participants’ quality of life. On the contrary, the findings of the study revealed no difference in the quality of life between new participants and old participants. This study may contribute to the policy implications of Amanah Ikhtiar Malaysia’s microcredit programme, especially in improving training and guidance.

Published: December 2020

Islamic banking dominates the largest market share of global Islamic finance assets. Thus, the performance of Islamic banks is crucial in shaping the future development of Islamic finance. This study aims to examine the performance of Islamic banks in the perspective of technological and productivity change based on the country level assessment. By adopting the Malmquist Index analysis, this study selected 44 Islamic banks from the top ten countries that had the largest Islamic banking asset for the period from 2015 to 2018. The findings reveal that the average productivity of Islamic banks has increased during the study period. Productivity improvements were supported by technological innovation, which significantly increased the level of productivity. Nevertheless, the high-tech expansion was not followed by an improvement in the efficiency level. This finding explains that the development of banking technology is not able to fully support the development of products and services.

Published: December 2020

Multiple antenna orthogonal frequency division multiple access (OFDMA) is a promising technique for the high downlink capacity in the next generation wireless systems, in which adaptive resource allocation would be an important research issue that can significantly improve the performance with guaranteed QoS for users. Moreover, most of the current
source allocation algorithms are limited to the unicast system. In this paper, dynamic resource allocation is studied for multiple antenna OFDMA based systems which provide multicast service. The performance of multicast system is simulated and compared with that of the unicast system. Numerical results also show that the proposed algorithms improve the system capacity significantly compared with the conventional scheme.

Published: December 2020

Informações quanto à suscetibilidade ou tolerância de espécies de maracujá (Passiflora spp.) à fitopatógenos, como os nematoides, são importantes no processo de escolha de porta-enxertos. Com esse trabalho, objetivou-se estudar a resistência de quatro espécies de maracujazeiros ao nematoide das galhas, Meloidogyne incognita. Adotou-se delineamento inteiramente casualizado, em esquema fatorial 4x4 (espécies x níveis de inóculo), totalizando 16 tratamentos com cinco repetições. As espécies utilizadas foram Passiflora alata, P. edulis, P. cincinnata, e P. giberti, submetidas à quatro níveis de inoculação com ovos de M. incognita: 0, 500, 1000 e 2000 ovos/vaso. O experimento foi conduzido em casa de vegetação, sendo cada parcela constituída de um vaso com 1 kg de solo autoclavado, contendo uma planta. Com 90 dias após a semeadura, pode ser observado que o volume de raízes foi dependente apenas da espécie, tendo P. edulis o maior volume. O número de galhas no sistema radicial foi menor em plantas de P. cincinnata, e no geral, o aumento do número de ovos no inóculo diminuiu o número de galhas. Todas as espécies apresentaram elevado número de indivíduos em suas raízes, acima de 8000, bem como elevado fator de reprodução. As espécies P. giberti e P. cincinnata apresentaram alterações no cilindro central das raízes, provocadas pelo ataque de M. incognita. Com esse trabalho, concluiu-se que as quatro espécies de maracujazeiros estudadas foram altamente suscetíveis a M. incognita.

Published: December 2020

O girassol é uma cultura que vem ganhando destaque no cenário nacional devido seu grande potencial para produção de óleo usado tanto para fins alimentícios como para produção de biodiesel. A compactação do solo pode limitar o crescimento e desenvolvimento das plantas. O objetivo deste trabalho foi avaliar o desenvolvimento do girassol submetido a cinco níveis de compactação do solo. O experimento foi instalado em cultivo protegido, em Latossolo Vermelho Distroférrico com textura argilosa. Foi utilizado colunas de PVC de 200 mm de diâmetro dividido em três anéis sendo uma camada inferior de 200 mm de altura e uma camada superior com 100 mm de altura, com um anel intermediário com 50 mm de altura com o solo compactado. O anel intermediário possui cinco diferentes densidades sendo respectivamente 1,0; 1,1; 1,2; 1,3 e 1,4 Mg m-3. Aos 40 dias após a emergência das plantas, foram determinadas: número de folhas, altura de plantas, massa seca da parte aérea, diâmetro do caule, massa seca de raiz e comprimento de raiz. A compactação do solo até a densidade de 1,4 Mg m-3 não prejudicou o número de folhas e massa seca de parte aérea do girassol. As densidades de 1,3 e 1,4 Mg m-3 tiveram um impacto negativo na altura de planta, diâmetro de caule, comprimento e a massa seca de raiz, prejudicando o desenvolvimento inicial da cultura.

Future of the Earth-atmosphere system will depend, to a large extent, on our capability of understanding all the processes driving climate change and, in this context, of outstanding importance are the monitoring and the investigation of greenhouse gases (GHGs), as main drivers of the Earth’s climate change. With this idea the project INMENSE (IASI for Surveying Methane and Nitrous Oxide in the Troposphere) was born, which aims to improve our current understanding of the atmospheric budgets of two of the most important well-mixed greenhouse gases, methane (CH4) and nitrous oxide (N2O). To this end, INMENSE has generated a new global observational data set of middle/upper tropospheric concentrations of CH4 and N2O from the space-based remote sensor IASI (Infrared Atmospheric Sounding Interferometer), on board the meteorological satellites EUMETSAT/Metop. In this work the INMENSE IASI CH4 and N2O products are presented, characterized and comprehensively validated by using a multiplatform reference database (aircraft vertical profiles, ground-based in-situ and remote-sensing observations). This extensive validation exercise suggests that the IASI CH4 and N2O products shows a precision between 1-3% and a bias of 2% as well as they are consistent temporally and spatially. Finally, the CH4 and N2O IASI observations over the Iberian Peninsula have been compared to MOCAGE chemical transport simulations, assessing the degree of agreement between both datasets.

Authors: Laverdure Patricia , Beisbier Stephanie
Published: December 2020

Importance: The findings support the use of occupation- and activity-based interventions to improve the occupational participation of children and youth with disabilities.

Objective: To examine the effectiveness of occupation- and activity-based interventions to improve participation and performance in activities of daily living (ADLs), play, and leisure in children and youth.

Data Sources: MEDLINE, PsycINFO, CINAHL, ERIC, OTseeker, and Cochrane Database of Systematic Reviews; reference lists of retrieved articles; and tables of contents of selected journals were searched to identify peer-reviewed studies published between 2000 and 2017.

Study Selection and Data Collection: Studies addressing occupation- and activity-based interventions and outcomes for children ages 5 to 21 were selected and appraised using Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines, evaluated for risk of bias, and synthesized to develop practice recommendations.

Findings: Fifteen Level I (meta-analyses, systematic reviews, and randomized controlled trials), 5 Level II (two groups, nonrandomized), and 3 Level III (one group, pretest–posttest, retrospective) studies were examined and categorized by type of intervention and outcome. Each study used occupation- or activity-based interventions and reported ADL, play, or leisure outcomes. Intervention themes identified include supporting engagement in occupations, supporting participation with cognitive supports, and using technology to support occupational participation and performance.

Conclusions and Relevance: Strong evidence indicates that engagement in occupations and activities, practice within and across environments, and coaching and feedback improve participation and performance in ADLs and functional mobility. Moderate evidence supports the use of collaborative goal setting, modeling, and guided participation in play and leisure. Moderate evidence also supports technological interventions for ADL, play, and leisure performance.

What This Article Adds: Engaging children and youth in occupations and activities; providing guidance in goal direction, planning, and feedback to enhance their participation; coaching caregivers in effective carryover; and providing technology-based intervention can improve the occupational participation and performance of children and youth.

Published: December 2020

Obtaining information about the shape and volume of the bladder plays a significant role in determining the pathologies of this organ. To collect the relevant data, the first thing to do is to separate the bladder from the background on the ultrasound image. The article is devoted to automation this process using an algorithm based on the Unet architecture with a pretrained imagenet encoder (encoder – ResNet50). The article gives a comparative analysis of some well-known methods in the literature that improve the accuracy of the proposed algorithm. The quality of the basic architecture has been improved by more than 4 percent on the PR AUC metric (from 84.49% to 89.62%) in the series of experiments with the help of automatic annotation of previously unmarked data. In addition, there are two important results showing practical effectiveness of using the data from another medical task (which raised the accuracy to 88.50%) and using time-dependent sequence of frames inside the video (raised the quality to 88.19%).
A Method for Actin Filament Tracking in Fluorescent Microscopy Images
Authors: Kononykhin Danil , Berg Valentina , Krylov Andrey , Sorokin Dmitry
Published: December 2020

The automated tracking of subcellular structures in live microscopy image sequences is an actual problem in many biological research areas. A universal solution for this problem still does not exist due to a huge variety of data of different nature. In this work, we propose an algorithm for tracking actin filaments in 2D fluorescent image sequences. The filaments are moving in a random and abrupt manner frequently crossing each other. We used steerable filters based ridge detection followed by crossing filaments correction algorithm for filaments detection. The tracking was performed using a greedy nearest neighbor method. The quantitative evaluation of our approach was performed on several manually annotated image sequences using the object tracking quality metric MOTA. It was shown that the proposed approach outperforms an existing approach in tracking accuracy. In addition, the proposed approach allows processing crossed filaments, unlike the existing methods.

The paper proposes a solution to the problem of detecting oil pollution on a monochrome radar image. The detection of oil pollution in the image includes the solution of three tasks: detecting a dark object on the image, highlighting the main characteristics of a dark object, classifying a dark object as oil pollution or natural slick. Various characteristics of a dark object are proposed based on the contrast between the object and the background. It is proposed to use a neural network as a classifier. The input parameters of the neural network classifier of the dark image object are proposed. A technique for determining the structure of a neural classifier is presented. An algorithm for testing the selected structure of the neural network for the suitability of classifying the dark area on the image of the water surface as oil pollution or wind slick is proposed. The results of the work of the neural network classifier program for detecting abnormal objects in radar images are demonstrated.

Published: December 2020

The article is devoted to algorithms developed for solving the problem of placement orthogonal polyhedrons of arbitrary dimension into a container. To describe all free areas of a container of complex geometric shape is applied the developed model of potential containers. Algorithms for constructing orthogonal polyhedrons and their subsequent placement are presented. The decomposition algorithm intended to reduce the number of orthogonal objects forming an orthogonal polyhedron is described in detail. The proposed placement algorithm is based on the application of intersection operations to obtain the areas of permissible placement of each considered object of complex geometric shape. Examples of packing sets of orthogonal polyhedrons and voxelized objects into containers of various geometric shapes are given. The effectiveness of application of all proposed algorithms is presented on an example of solving practical problems of rational placement of objects produced by 3D printing technology. The achieved layouts exceed the results obtained by the Sinter module of the software Materialise Magics both in speed and density.

Published: December 2020

The analysis of a surface generated by quasi-rotation of a straight line around a circle is provided in the present paper. The considered case features a straight generatrix belonging to the plane of a circular axis of quasi-rotation and intersecting it in two points. A geometric method of determination of a point belonging to a surface given its projection on the axis plane is demonstrated. Geometric construction of the curves of intersection between the considered surface and a conic surface is presented. A method of determination of points belonging to the considered surface as points belonging to the curve of intersection of two conic surfaces is acquired. Step-by-step constructions illustrating the solution of the problem of determination of a plane tangent to the considered surface in a given point are provided. The problem is solved through the methods of descriptive geometry. Every construction is performed according to an analytic algorithm, not involving approximate methods of determination of the sought points. The construction is carried out in a CAD system through the use of tools “straight line by two points” and “circle by center and point”. The presented solution to the defined problem is connected to the solution to the problem of determination of the rays reflected from the considered surface. The results of the paper expose the geometric properties of surfaces of quasi-rotation. The provided constructions can serve as the basis for the research of optical properties of the considered surfaces.

Specialized software that supports existing approaches to processing images of the crystal structure of materials for analyzing transmission electron microscopy images have a lot of different digital image processing methods, but major part of it are weakly automated. Automatic algorithm is able to make the crystal structure analysis more fast and effective process. The paper considers the problem of automated processing of SAED images of transmission electron microscopy. Proposed automated image processing algorithm based on methods of adaptive binarization and Watershed segmentation allows one to determine the distances on the diffraction pattern of a material sample on the image of transmission electron microscopy. The proposed algorithm has been tested on several SAED images, distances were calculated in automatic mode and compared with the results of semi-automatic measurement in Digital Micrograph GMS 1.8 software. The analysis of the results showed high agreement in considered cases, which let us assume that proposed algorithm has good development prospects.

Impact Factor of a Term: a Tool for Assessing Article's Future Citations and Author's Influence Based on PubMed and DBLP Collections
Authors: Charnine Michael , Khakimova Aida , Klokov Alexey
Published: December 2020

This article describes a new bibliometric indicator called Impact Factor of a Term (IFT) that helps to predict future impact of scientific works and/or the author. The predictive properties of IFT are proven by two examples of different collections of scientific articles. It is shown that the correlations of the current and future IFT values depending on the trend are practically similar for both collections. The graphs of IFT correlations of the current and future years depending on the number of articles with the word/term are presented. The graphs show that the higher the current frequency of the term and the number of articles with this term, the greater the correlation and stability of IFT. The stability of IFT helps to accurately predict the number of future citations. The list of the most informative words/terms with the largest total values of IFT multiplied by the current frequency is analyzed. It has been shown that the size of collection affects the stability and predictive properties of IFT. The words and terms with high IFT values allow us to judge the future impact of an article and its author based on the prediction of future citations. Such words also help identify promising research directions.

Considering people who are in a coma, doctors have to rely on physical clues and information provided by monitoring systems. It is commonly used for patients in a vegetative state, as contact with them is difficult. Taking into account the typical workload of the doctor, they require several tools to monitor the coma depth, since it is hard to perform a clinical evaluation hourly. Therefore, visual perception and monitoring of physical state for coma personnel proved to be more convenient for prompt decision-making. In a number of cases, it would be possible to make a prognosis for their recovery and monitor effectiveness of treatment courses. Visual control system based on RGB led strips according to the ANI range of values was created. In conclusion, the connecting scheme of ANI monitor with the implementation of visual object was presented.

Published: December 2020

The article discusses the use of a project-based interdisciplinary practice-oriented approach in the implementation of BIM technologies in the educational process for senior students of architectural and civil engineering universities. At the initial stage of the educational process, BIM technologies are introducing by supplementing the relevant sections in the existing courses. When teaching senior students, it is proposing to organize interdisciplinary student teams to solve cases based on real problems on a competitive basis. The demand for the implementation of information design technologies in the construction industry is steadily growing, thanks to the competitive advantages gained by the player in the construction market when introducing BIM technologies, however, the complexity of training specialists across the entire spectrum of functional capabilities. The use of this technology prevents the active transition of players in the construction market to the full use of building information modeling technologies, which confirms the relevance of the chosen topic. The article also examines the shortcomings of the existing education system. The method proposed by the author is not traditional in the educational system and requires a review of the existing educational tradition in technical universities.

Published: December 2020

This article presents the problem of developing an algorithm for automated reading of a drawing of an object, consisting of three types with the necessary cuts. According to the drawing, a partition of the object into nonderivative figures should be obtained and boolean operations should be identified, with the help of which the final composite figure will be constructed from non-derivative figures. Thus, in the process of solving this problem, a socalled binary tree of the modeled composite figure will be generated. Moreover, it is necessary to take into account the multiplicativity of the solution to this problem and the possibility of choosing optimal solutions. This paper poses a specific problem, in which non-derivative figures can be got using four formbuilding operations available in the arsenal of tools for getting three-dimensional elements in the Compass 3D geometric modeling system, namely, such operations as "extrusion", "rotation", "along the trajectory" and "cross-sections".

Polymeric materials are actively used to upgrade existing optical devices in order to improve their physical and optical properties. High-tech and relatively cheap polymer optics is a means of solving technical problems related to reduction of assembly labor intensity, improvement of design and reliability of various optical systems. Currently, ophthalmology is the most advanced area for polymer technology development. The defining trend of improving spectacle optics is gradual replacement of lenses made of silicate glass with lenses made of polymer materials, the undoubted advantages of which are almost twice lower density and significant impact resistance. This work is devoted to the development of an optical system of telescopic glasses of small multiplicity, made by the scheme Galileo using modern optical polymers. The device is designed to improve the performance of the eye and can be used for medical operations. The calculation of the presented optical system is carried out by the Zemax program. The resulting optical system is characterized by high image quality, light weight and compactness.

Published: December 2020

Recently many modern instruments and systems have been developed to study the Sun. For that, spectral instruments with high spectral resolution are most often used. It is relevant to achieve high spatial resolution along with spectral one for many scientific tasks. In practice, the achievement of both high spectral and spatial resolution can be done by the use of integral field spectroscopy. Current paper is devoted to searching for a system solution for an integral field unit (IFU), which will be implemented to the optical system of solar telescopecoronagraph. The diameter of the main mirror is D = 3 m. Telescope’s working spectral range is ∆λ = 390 − 1600 nm. The integral field unit is based on reflective elements. It divides the input field of a rectangular shape with a size of 0.7500 ×1200(0.145 mm×2.327 mm) into 8 parts with a size of 0.09400×9600(0.018 mm×18.617 mm) each. The possibility of creating an IFU optical system using a parabolic mirror for all (eight) channels is shown. The quality of the optical system was evaluated, as well as the effect of vignetting on the slicing mirrors.

Published: December 2020

This paper is devoted to the development of the ontology-driven standalone scientific visualization station based on a single-board microcomputer with custom tangible user interface. Such a station can be used as a powerful demonstration tool in various scenarios including interactive museum exhibitions. According to the approach proposed, the particular instance of a software scientific visualization system is generated automatically by a high-level platform SciVi that was been developed earlier. Previously, ontology-driven software generation mechanisms within SciVi were tested on the firmware generation for the microcontroller units. Currently we present a generalization of this technique to the case of systems on chips like Raspberry Pi or Orange Pi. Data preprocessing and rendering capabilities of SciVi are reused without modifications from the previous stages of development, while the new mechanisms of taking into account the specifics of systems on chips software and hardware organization are introduced via extending the appropriate SciVi ontologies. The generalized technique is tested in practice by creating a set of interactive museum items for the “Transmutations” exhibition within Kidsmuseum, branch of Perm Regional Museum.
