Ranking Japan’s Institutions of Higher Education, 2017: A Comparative Analysis
Authors: Cramer Kenneth M , Yoo Hyein , Manning Dana 
Published: January 2020

The present study examined the 2017 Times Higher Education annual rankings for Japanese institutions of higher learning. Based on the analytic model as mapped out previously using Canadian data, we offered a similar protocol for the top 100 institutions of higher education in Japan. Three analyses showed that: (a) overall rank correlated with individual index ranks for 9 of the 13 indices, (b) the schools appearing among the top institutions overall ranked significantly better on 8 of the 13 indices compared to schools appearing among the bottom institutions overall, and (c) schools were empirically grouped into four meaningful families or clusters whose constituent members shared a comparable profile of indices. We offer a juxtaposition of the present results to annual evaluations from Canada’s institutions of higher learning. The wider implications include an international comparison of institutions of higher learning, a proposed analysis protocol that Japanese education administrations may further pursue, and a categorical breakdown of educational institutions in Japan. Directions for future research are outlined.
A Genre-Based Investigation of the Introduction Sections of Academic Oral Presentations
Authors: Makhtiar Singh Kuldip Kaur , Mohamad Ali Afida , Chan Mei Yuit , Tan Helen 
Published: January 2020

The academic oral presentation (henceforth AOP) is an important genre for tertiary students across various courses and disciplines in the university. Despite the importance of AOPs for undergraduate students, relatively little is known about this genre. Using Swales’ (1990, 2004) notion of move analysis, this paper compares the rhetorical structure of the introduction sections of academic oral presentations from two different fields, namely English language and Administrative Sciences. The findings show some similarities in the AOPs whereby the introduction section contained three moves, and their related steps were similar to previous studies on the rhetorical structure of oral presentations but with few variations. The linguistic features used were also found to be similar in both corpora revealing that students were able to transfer their rhetorical knowledge and linguistic features from one context to another. This study reveals that variation in AOPs is possible in different courses and disciplines. Thus, having genre awareness can help students adapt their genre knowledge to the context.
Factors Affecting Bangladeshi Private University Students’ Choice of Institutions for Undergraduate Study
Authors: Anam Rumana Liza 
Published: January 2020

In a highly populated country like Bangladesh where standards of living are rising steadily, more and more students are pursuing studies at university level. With only a few publicly funded universities, private universities are now the main avenue for pursuing undergraduate studies. Competition is growing among these universities operating in a heavily regulated sector. Substantial amounts are often being spent on attracting potential students. However, without proper research into the area and understanding how students choose their universities, resources may end up being used ineffectively. This conceptual paper aims to identify the factors that students consider when choosing their universities.

Published: January 2020

Abstract
The classification and detection of defects play an important role in different disciplines. Research is oriented towards the development of approaches for the early detection and classification of defects in electrical drive systems. This paper, proposes a new approach for the classification of induction motor defects based on image processing and pattern recognition. The proposed defect classification approach was carried out in four distinct stages. In the first step, the stator currents were represented in the 3D space and projected onto the 2D space. In the second step, the projections obtained were transformed into images. In the third step, extraction of features whereas the Histogram of Oriented Gradient (HOG) is used to construct a descriptor based on several sizes of cells. In the fourth step, a method of classifying the induction motor defects based on the Support Vector Machine (SVM) was applied. The evaluation results of the developed approach show the efficiency and the precision of classification of the proposed approach.
An Eight-Node Hexahedral Finite Element with Rotational DOFs for Elastoplastic Applications
Authors: Ayadi Ayoub , Meftah Kamel , Sedira Lakhdar , Djahara Hossam 
Published: January 2020

Abstract
In this paper, the earlier formulation of the eight-node hexahedral SFR8 element is extended in order to analyze material nonlinearities. This element stems from the so-called Space Fiber Rotation (SFR) concept which considers virtual rotations of a nodal fiber within the element that enhances the displacement vector approximation. The resulting mathematical model of the proposed SFR8 element and the classical associative plasticity model are implemented into a Fortran calculation code to account for small strain elastoplastic problems. The performance of this element is assessed by means of a set of nonlinear benchmark problems in which the development of the plastic zone has been investigated. The accuracy of the obtained results is principally evaluated with some reference solutions.
Study of Powder Particle Size Effect on Microstructural and Geometrical Features of Laser Claddings Using Response Surface Methodology RSM
Authors: Boussaha El Hadi , Aouici Samia , Aouici Hamdi , Bahloul Abida 
Published: January 2020

Abstract
A continuous CO2 laser (10.6 µm wavelength) was adopted to investigate the influence of powder particle sizes on microstructural and morphological characteristics of laser claddings.
To study the potential of powder in controlling the incident laser energy, different average particle sizes of Ni-base powder were deposited on an austenitic stainless steel X3CrNi18-10 substrate. The energy value necessary to melt a mass m of powder was calculated. The results indicate that this energy decreases with particle sizes.
The claddings obtained with small particle sizes revealed a good morphological aspect and a low dilution of the cladding layer in the substrate, yet enough to create a very good metallurgical bond. The residual stress state was also influenced. Concerning modeling, we have elaborated residual stress model in the case of laser cladding by exploiting the response surface methodology (RSM), using a quadratic regression model. Combined effects of three laser cladding parameters on the residual stress is explored by a statistical analysis of variance (ANOVA). Results show that the residual stress is influenced principally by the power delivered by laser beam and by the scanning speed. It is also indicated that the size of powder particle is the dominant factor affecting the residual stress.
”You Must Swear [...] That Care for the Well-Being and Health of Women in Labor and Their Infants Shall Be the Only Objective of Your Work.” Midwives in the Galician Autonomy — Statistical and Geographical Analysis by Counties
Authors: Rejman Sabina 
Published: January 2020

Abstract
The study analyses the number of midwives in the counties of Eastern and Western Galicia in census years 1869, 1880, 1890, 1900 and 1910, and the ratios per cadastral commune, 10,000 square kilometers, 10,000 civilians and 10,000 women in a county. The analysis was based on Austrian and Galician statistical reports. The results of the study confirmed that Eastern Galicia outnumbered Western Galicia in terms of midwives. However, it was in Western Galicia where the rate of growth was higher, and the effects of the 1910 collapse more moderate. This could have been due to an amendment to the 1897 midwifery regulations. The position of individual counties changed, depending on the year and the specific measure. In Eastern Galicia, Lisko county ranked the worst and Horodenka, Śniatyń, Tarnopol, Trembowla, and Brzozów counties ranked the best. In Western Galicia, Limanowa county ranked the worst, while Brzesko, Kraków, Łańcut, Wadowice, Przeworsk, and Podgórze counties ranked the best. There is a strong positive correlation between the rank and natural conditions (water, soil, climate), type of crops, agricultural development and processing, transport system (road and rail), population, and stimulating function of large urban centers. Favorable conditions were correlated with higher values in measures of the number of midwives.
Globalisation and Women’s Work in the Beedi Industry
Authors: Pande Rekha 
Published: January 2020

Abstract
The present paper views globalisation and women’s work and exploitation in a micro enterprise in India, the beedi (indigenous cigarette) industry with a case study from one of the states in India. Rural occupational structures and employment patterns in India have undergone a transition in the last few decades due to globalisation. Newer forms of employment like construction work, domestic services and beedi making have become alternatives to agricultural labour for women. Beedi is an indigenous cigarette, in which tobacco is rolled in a tendu leaf and tied with a cotton thread. This is smaller and less expensive than a cigarette and in the popular imagination it stands for the working class. This work is done sitting at home and mostly women and girls do it. This is a very gendered industry, for only women and girls that too from low-income groups make beedis. There is a lot of exploitation in this industry and this has only increased with the advent of globalisation but this is generally ignored by data gathering systems, policy makers and administrators. There is an occupational health hazard too for many of these workers suffer from various health hazards not because they are smoking these beedis but because they are making them.
Influence of Family Benefits on Women’s Professional Activity. The cases of Poland, the United Kingdom, and France
Authors: Kacperska Magdalena 
Published: January 2020

Abstract
Women show greater and greater activity on the job market, they obtain better positions, salaries, etc. However, the statistics concerning their professional activity differ from those of men. We should take into consideration the fact that women are the ones who give birth to children and, in majority, take care of their upbringing, especially in the first years of child’s life. Policies of particular states are different in terms of the amount and availability of family benefits, and that can be reflected in women’s willingness to return to work.

Process Safety in Contaminated Groundwater Treatment Plants
Authors: Cherubin Paolo , Presotto Lucia , Frattini Luca 
Published: January 2020

In many Countries legislation forces Oil&Gas Companies to implement a Process Safety Management System (PSMS) to prevent and mitigate major accidents associated to the release of energy or hazardous substances. In plants where activities may have lower process risks, such as contaminated groundwater treatment plants, the implementation of a PSMS usually is not mandatory. This paper outlines how also these plants could benefit from a Process SafetySafety framework.
A PSMS can be developed in line with the framework of an internationally recognized organization (CPPS, Energy Institute, IOGP, OSHA) to be applied to activities with significant HSE risks while it may be considered as an internal standard for low-risk activities. The effectiveness of the PSMS adopted and its correct and complete implementation in accordance with the selected framework may be evaluated by a dedicated audit protocol. The typical findings from audits carried out on reference upstream and downstream installations as well as on some low-risk plants were collected and performance compared in order to identify peculiarities in terms of good practices and recurrent areas for improvement.
The main results of the benchmark are presented in this paper. The results confirm that the effectiveness of a PSMS is strictly linked with the level of risks in the activities and how such risks are managed both in administrative and operating processes. A robust risk-based approach in all processes, fostered by a visible commitments of top management, is the successful key for enhancing the Process Safety culture of personnel and ensuring safe performances and business continuity in operations, irrespective of the risk level in activities.
The paper also provides a roadmap for implementing a PSMS in contaminated groundwater treatment plants, tailoring the Process Safety framework to the specific operative needs and risks.
Application of Different Fluid Injection Methods to Reduce Breakdown Pressure
Authors: AlTammar Murtadha J. , Gala Deepen P. , Sharma Mukul M. 
Published: January 2020

Using hydraulic fracturing laboratory experiments, we previously showed that different fluid injection methods for pressurizing a borehole lead to significant variations in specimen breakdown pressure. In this paper, we present a numerical analysis of these experiments to investigate the mechanism behind such variations.
A multiphase, poro-elastic numerical simulator is developed and utilized in this work. The equations for multiphase, multi-component fluid flow in a deforming porous medium are described and the solution algorithm used in the numerical simulator is explained. The simulator is verified against a Buckley-Leverett solution for multiphase flow and against Mandel's compaction problem for poro-elasticity. We constructed a two-dimensional (2D) numerical model with the same dimensions and properties of the laboratory specimen. The specimen is a square sheet with a circular borehole in the middle, and anisotropic far-field stresses are applied to the specimen. A total of five fluid injection cases were simulated. In the first four cases, glycerin was injected into initially dry specimens (air-saturated at atmospheric pressure) using a) fast injection rate, b) slow injection rate, c) cyclic pressure ramp, and d) constant pressure injection. Glycerin was injected in the fifth case into an initially glycerin-saturated specimen using the same fast injection rate in the first case.
As the fluid is injected into the specimen, we demonstrate the advancement of fluid saturation front and the development of pore pressure and effective hoop stress around the borehole for the five fluid injection cases. At the end of injection, it is clearly shown that the extent of glycerin infiltration or leakoff into the specimen is smallest for the fast injection, and becomes respectively larger for the slow injection, cyclic pressure ramp, and constant pressure injection. The higher fluid leakoff among the different cases also corresponds to higher pore pressure distributions and induced tensile stresses around the borehole that reduce the required breakdown pressure. The induced hoop stresses are most tensile for the constant pressure injection and least tensile for the fast fluid injection. We show that the least tensile stress using the fast fluid injection becomes the most tensile among all five cases when the specimen is fully saturated with glycerin initially.
This study draws a novel linkage between four different topics that are investigated separately in the literature: 1) the effect of fluid injection rate on breakdown pressure, 2) the effect of cyclic borehole pressurization on breakdown pressure, 3) the effect of constant pressure injection on breakdown pressure (static fatigue behavior), and 4) the effect of rock saturation on breakdown pressure. In terms of field applications, the fundamental findings from this study are utilized to develop new methods for pre-frac injection tests to reduce breakdown pressure in highly-stressed formations.
