Authors: Zhang Lanfang , Zhang Zhiyong , Zhao Ting
Published: March 2021

With the rapid development of mobile internet, a large number of online social networking platforms and tools have been widely applied. As a classic method for protecting the privacy and information security of social users, access control technology is evolving with the spatio-temporal change of social application requirements and scenarios. However, nowadays there is a lack of effective theoretical model of social spatio-temporal access control as a guide. This paper proposed a novel spatio-temporal access control model for online social network (STAC) and its visual verification, combined with the advantages of discretionary access control, using formal language to describe the access control rules based on spatio-temporal, and real-life scenarios for access control policy description, realizes a more fine-grained access control mechanism for social network. By using the access control verification tool ACPT developed by NIST to visually verify the proposed model, the security and effectiveness of the STAC model are proved.

Authors: Kalra Siddharth , Jain Sarika , Agarwal Amit
Published: March 2021

This paper proposes to create an augmented reality interface for the visually impaired, enabling a way of haptically interacting with the computer system by creating a virtual workstation, facilitating a natural and intuitive way to accomplish a multitude of computer-based tasks (such as emailing, word processing, storing and retrieving files from the computer, making a phone call, searching the web, etc.). The proposed system utilizes a combination of a haptic glove device, a gesture-based control system, and an augmented reality computer interface which creates an immersive interaction between the blind user and the computer. The gestures are recognized, and the user is provided with audio and vibratory haptic feedbacks. This user interface allows the user to actually “touch, feel, and physically interact” with digital controls and virtual real estate of a computer system. A test of applicability was conducted which showcased promising positive results.
Sulforaphane in experimental hypertension
Authors: Banigesh Ali , Senanayake Vijitha , Bukhatwa Salma , Juurlink Bernhard
Published: March 2021

Background: Hypertension is defined as a failure to achieve a blood pressure (BP) target – smaller than 140/90 mmHg. The worldwide burden of hypertension has been associated with globally increased rates of death and disability. There is increasing evidence of strong relation between hypertension and oxidative stress, where either increased oxidative stress or depressed antioxidant level may lead to hypertension. Using stroke-prone spontaneously hypertensive rats (SHRSP) rats, previous studies in our laboratory have shown that broccoli sprouts (high in sulforaphane, a phase-2 protein inducer) attenuate BP and inflammation. Objectives: The question this study addressed was whether sulforaphane (a potent phase-2 protein inducer) can attenuate hypertension in the experimental model using the stroke-prone spontaneously hypertensive rats (SHRsp). Materials and Methods: Sulforaphane (LKT Laboratories) or vehicle was orally gavaged to SHRsp or Sprague–Dawley rats (SD) daily for 15 weeks. The body weight and BP were determined weekly, using a standard tail-cuff BP measurement. Tissues such as hearts and kidneys were collected, weighed, and stored under −80°C for further analysis. Results: When compared to BP in SHRsp control rats (179.9 ± 4.32), sulforaphane significantly reduced BP to 157 ± 5.21 (10 μmol/kg body weight), 136.57 ± 1.96 (20 μmol/kg body weight), and 129.33 ± 6.10 (5 μmol/kg body weight), respectively, in SHRsp rats. Conclusion: Administration of sulforaphane, a potent phase-2 enzyme inducer, daily for more than 3 months, significantly improves BP in SHRsp rats, but it did not have any effects on normotensive rats – SD.

Published: March 2021

Transmission of Chagas disease (CD) has decreased in recent decades, but the disease remains an important problem in endemic areas. There was an increase in the proportion of nonvector transmission, mainly in non-endemic countries. The aim of this study was to gather evidence concerning healthcare professional’s knowledge about CD. Searches were performed through Medline/PubMed, Lilacs, Web of Science databases, and Scielo archives, from which 13/97 articles were selected for a qualitative analysis after full-text reading. Most of the studies were from the United States, the oldest published in 2007 and the most recent in 2020, and most of them used surveys as the evaluation method. Each article used different methods, according to the epidemiological status of vector transmission. Two studies targeted specialty-related questions, and two used focus groups as methods for data gathering. Despite differences between the studies, all of them presented knowledge deficits among healthcare workers, regarding at least one of the evaluated aspects. In comparison with population surveys, healthcare professionals demonstrated higher results related to clinical aspects and awareness of the disease’s importance. Most of the articles showed a low perception of CD’s knowledge by the participants and a low probability of considering CD in the diagnosis of their patients. A previous contact with the subject was pointed by some studies as capable of improving knowledge of the participants. This study emphasizes the importance of continuing education to address deficits of healthcare professionals’ knowledge.
Food Security and COVID-19 in Africa: Implications and Recommendations

Published: March 2021

Before the COVID-19 pandemic ravaged Africa, a large percentage of Africans were already affected by poverty and food insecurity. The pandemic wreaked havoc on their already unfavorable situation. The direct and indirect impacts of COVID-19 included but not limited to illness and deaths of food systems’ workers, interruption of food supply chains, unemployment, depreciation of currency value, and disruption of social protection programs. COVID-19 will lead to further economic fallout. Thus, the situation needs careful observation and timely intervention to safeguard the vulnerable African communities. Although Africa has sought ways to lessen the dire impact of the pandemic on food security, short-term solutions should include and enhance social and economic relief initiatives such as monetary intervention and social safety net. Considering a balance between health benefits of COVID-19 restrictions and their economic implications, the African countries, at the regional level, must preserve open and efficient social protection programs and cross-border supply and distribution networks for agricultural inputs. Africa’s medium- and long-term strategies for improving food security should include improving and diversifying its agricultural productivity and production of key food commodities. This will reduce Africa’s dependence on importation of these key commodities, and will help the continent address underlying economic vulnerabilities and better manage food, pandemic, and/or health-related crises affecting food security in the long term.
Determination of Effect of Quenching Parameters on Mechanical Properties of Industrial Steels by Experimental and Simulation Analysis
Authors: Dubey Mukesh Kumar , Das Suman , Datta Simmi , Mahapatra Rajendra , Harinarain Ajay , Saxena Deepak
Published: March 2021

One of the most critical parts of the heat treatment process is the quenching operation, which is defined as rapid cooling of a work-piece by immersing it into a quenching media such as water, oil, or polymer. Quenching is carried out for altering and achieving the desired mechanical properties of industrial materials. Hardness, microstructure changes, and surface finish obtained are a few of the most sought objectives of quenching and these are greatly influenced by cooling time, cooling rate, quench media, etc. The cooling rate of quenchant must be sufficiently fast for phase transformation of the material, thus changing the microstructure. But, very fast quenching may result in distortions or crack formation on the material. Therefore it is very critical to have comprehension and control over the quenching process.

Normally a probe made up of Inconel 600 is used in a potable quenchometer to comparatively evaluate the cooling rate with different quenchants. The authors, in this study, have got fabricated specimens made up of two industrial-grade steel namely, SS 304 (less heat treatable) and EN 8 (more heat treatable) in addition to the standard Inconel Probe for determination of cooling rate thru' experiment. Experiments were performed with Servo-Quench 11 oil quenchant in accordance with ASTM standard. Cooling curves and cooling rates were used to determine microstructure changes and hardness achieved in the material by the inverse-iteration method. A software was used for modelling and simulations to generate quench outputs numerically. The experimental results were validated by the numerically simulated results.

The analysis shows that the quenching process is highly influenced by metallurgy, quenching medium, and HTC. Experimentally measured micro-structural changes and hardness achieved were observed and have been presented in this work. With the appropriate assumption of boundary conditions and thermal properties, the quench result can be simulated for other grades of steel.

In the case of fire in infrastructure works, the bearing capacity of reinforced-concrete structures will be reduced due to the effect of high temperatures. So, the refractory concrete with good thermal properties contributes an important role in reducing the impact of fire on the durability of the building. Nowadays, calcium aluminate cement is widely used for that thanks to the thermal stability of the respective concrete by the high content of aluminum. This paper presents experimental and numerical results of heat transfer in cylindrical specimens of calcium aluminate cement-based refractory concrete. As experimental results, with a calcium aluminate content of about 50% in concrete, its thermal properties have been significantly improved in comparison with other types of cementitious concrete. The evolution of temperature as a function of time (inside and outside of the concrete specimen) was also recorded and analyzed. In the 3-D model, the thermal properties of refractory concrete were used from the previous experimental results. The results of this model were used to compare with experiments, then analyze and evaluate factors affecting the model results. The numerical model could also be exploited to determine the thermal parameters in the heat transfer in refractory concrete specimen.

Enabling Outcomes for Students with Developmental Disabilities through Collaborative Consultation
Authors: Villeneuve Michelle , Hutchinson Nancy
Published: March 2021

Collaborative consultation has been widely adopted in school-based occupational therapy practice; however, limited research has examined how collaboration between educators and occupational therapists contributes to students’ outcomes. The purpose of this study was to describe the nature of collaborative working in two cases of school-based occupational therapy service delivery. This paper reports a cross-case analysis, comparing findings about the nature of a joint effort in each case study to identify workplace practices that facilitated educator-occupational therapist collaboration. Ethnographic case study methods (Stake, 1995; Wolcott, 2008) and socio-cultural activity theory (SCAT; Engeström, 2001) were used to examine multiple perspectives concerning school-based occupational therapy collaborative consultation for two students with developmental disability in one region of Ontario, Canada. Cross-case analysis (Stake, 2006) facilitated examination of the similarities and differences in teamwork. Specific ways that educator-occupational therapist collaboration can be facilitated were identified in three areas: (a) focus for educational programming; (b) communication practices; and (c) leadership practices of educators. SCAT provided a robust framework for describing the depth, quality, and context of interactions from multiple stakeholder perspectives. As such, this research contributes to the development of theoretical and empirical perspectives on the processes of collaborative working and the relationship of these processes to outcomes.

Authors: Gupta Ritu , Banerjee Pratyush , Gaur Jighyasu
Published: March 2021

This study is an attempt to strengthen the existing knowledge about factors affecting the adjustment process of the trailing expatriate spouse and the subsequent impact of any maladjustment or expatriate failure. We conducted a qualitative enquiry using grounded theory methodology with 26 Indian spouses who had to deal with their partner’s expatriate assignment relocation. The open and axial coding techniques and the process of theoretical sampling are discussed at length. Our investigation reveals the recurrence of several factors earlier studied in previous models such as cultural novelty, family and peer support, the organization’s support and the spouse’s personality. Additionally, we found that the Indian spouses’ adjustment to expatriate assignments was influenced greatly by their perceived gender-role ideology and their marital obligations to their partners. The resulting extended model of spousal adjustment to expatriate adjustments may help management practitioners to enhance expatriate success in global assignments.

Qualitative Analysis Techniques for the Review of the Literature
Authors: Onwuegbuzie Anthony , Leech Nancy , Collins Kathleen
Published: March 2021

In this article, we provide a framework for analyzing and interpreting sources that inform a literature review or, as it is more aptly called, a research synthesis. Specifically, using Leech and Onwuegbuzie’s (2007, 2008) frameworks, we delineate how the following four major source types inform research syntheses: talk, observations, drawings/photographs/videos, and documents. We identify 17 qualitative data analysis techniques that are optimal for analyzing one or more of these source types. Further, we outline the role that the following five qualitative data analysis techniques can play in the research synthesis: constant comparison analysis, domain analysis, taxonomic analysis, componential analysis, and theme analysis. We contend that our framework represents a first step in an attempt to help literature reviewers analyze and interpret literature in an optimally rigorous way.
Getting to Grips with Bricolage: A Personal Account
Authors: Wibberley Christopher
Published: March 2021

This paper presents a personal account of how a PhD supervisor came to an understanding of an approach to research that was unfamiliar to him. Additionally it addresses the question of what makes the approach, in this case bricolage, an acceptable format for academic work and in particular PhD study. Bricolage is a relatively little used approach to research; therefore, researchers utilizing bricolage as a research design have less exemplary texts to draw on in coming to their own understanding of this approach to research. This paper presents an account of getting to grips with bricolage as a way of undertaking research, of potential interest as an exemplar generally (and specifically in relation to bricolage) to supervisors, examiners and students alike.

Published: March 2021

This research aims to improve an understanding of the lived experience of the gender diversity of respondents in the Pakistani context. It provides a rich description of the influence that gender diversity had on the organizational culture and the employees. Specific benefits anticipated by the organization, from implementation of gender diversity and related challenges were explored. In depth interviews were conducted with key personnel including HR managers assigned with a specific task to implement gender diversity across the organization. The findings reveal that a lot of concentrated efforts have been put in to eradicate the mental barriers within the system and also inculcate the culture of diverse sets of people, especially gender, allowing multiple and diverse opinions within the organization. Targeted efforts towards gender diversity have started showing its fruits; as such implementation has led to improved performance for the organizations and creation of job opportunities for the female gender, which may have been ignored earlier. Moreover, the organization strongly believes that ongoing efforts will yield better results. Therefore, focused efforts, initiatives and constant messages to change the mindset need to continue. The trustworthiness of the data will be established through triangulation and a chain of evidence has been established between the research objective, research questions and the interview data.
Extended Convergence of a Two-Step-Secant-Type Method Under a Restricted Convergence Domain
Authors: ARGYROS IOANNIS K. , SANTHOSH GEORGE
Published: March 2021

We present a local as well as a semi-local convergence analysis of a two-step secant-type method for solving nonlinear equations involving Banach space valued operators. By using weakened Lipschitz and center Lipschitz conditions in combination with a more precise domain containing the iterates, we obtain tighter Lipschitz constants than in earlier studies. This technique lead to an extended convergence domain, more precise information on the location of the solution and tighter error bounds on the distances involved. These advantages are obtained under the same computational eﬀort, since the new constants are special cases of the old ones used in earlier studies. The new technique can be used on other iterative methods. The numerical examples further illustrate the theoretical results.

Dans un premier temps cet article montre la méthode que M. Boegner a utilisée pour présenter celui qui fut son « père spirituel » ; de fait, il a eu recours à de très nombreuses citations, car il a voulu « faire parler Fallot ». Ensuite, à l’aide de quelques exemples, l’article expose comment M. Boegner a retracé les principaux aspects de la vie et de la pensée de T. Fallot.
Marc Boegner, une conscience missionnaire à l’épreuve des événements
Authors: Zorn Jean-François
Published: March 2021

La présidence du Comité directeur de la Société des Missions évangéliques de Paris que Marc Boegner assume de 1948 à 1968 ne résume pas son engagement au service de la mission, bien qu’elle se déroule à une période décisive de la vie de la Société, avec l’accession à l’autonomie ecclésiale des neuf champs de mission d’Afrique, de Madagascar et du Pacifique et son effacement comme Société issue du Réveil du XIXe siècle. C’est à la charnière des XIXe et XXe siècles que la conscience missionnaire de Boegner est éveillée, sous l’influence de ses deux oncles, les pasteurs Tommy Fallot et Alfred Boegner ; le premier, auquel il succède dans la paroisse d’Aouste (Drôme) en 1904, est à la source de sa vocation pastorale et de sa découverte des prémices de la synodalisation du mouvement missionnaire ; le second, qui l’appelle en 1911 à la direction de l’École de formation des missionnaires de la Mission de Paris, façonne sa spiritualité. Marc Boegner entre au Comité en 1919 et, jusqu’en 1939, date à laquelle il en devient vice-président, il théorise deux sujets déterminants de son engagement : les liens structurels mission et unité des Églises et les rapports problématiques mission et colonisation. Parmi les événements qui éprouvent sa conscience missionnaire, sans toutefois l’affaiblir, son voyage à Madagascar à la suite de l’insurrection nationaliste de mars-avril 1947 : il découvre que leurs revendications indépendantistes doivent être accordées sans confusion à celles qui portent les Églises à revendiquer leur autonomie. Cette expérience le guidera dans les visites ultérieures rendues aux Églises auxquelles il vient, au nom de la Mission de Paris, octroyer l’autonomie.
Le pasteur Boegner
Authors: Willaime Jean-Paul
Published: March 2021

L’œcuménisme occupe une place centrale dans la vie du pasteur Boegner, tout particulièrement celui qui a abouti à la formation du Conseil Œcuménique des Églises en 1938 (première assemblée à Amsterdam en 1948) et dans lequel il exerça diverses responsabilités. À côté de cet œcuménisme à dominante anglicane et protestante, l’expérience œcuménique de Boegner, c’est aussi l’œcuménisme catholico-protestant (il assista aux troisième et quatrième sessions du concile Vatican II en 1964-1965) et celui de la communauté de Taizé pour lequel il éprouva une certaine fascination. L’article montre quels sont les atouts personnels et sociaux ayant permis à ce notable protestant français d’avoir une carrière œcuménique internationale. Il analyse ensuite les caractéristiques de son positionnement œcuménique centré sur l’unité de l’Église au-delà de la diversité des Églises, une spiritualité interconfessionnelle et le témoignage chrétien dans la cité. Missionnaire de l’œcuménisme en France et dans le monde, cet ancien président de la Fédération Protestante de France (de 1929 à 1961) exprima sa déception face à ce qu’il percevait comme une frilosité œcuménique des protestants français.

Evolution of International Peace and Conflict Resolution Studies
Authors: Habibal Omar
Published: March 2021

In this paper review of the International Peace literature, specifically exploring the contemporary trends that function to align International Peace theory and practice with dominant interests. I begin with a critical historical overview of the development of this field, looking at the primary influences that have shaped and continue to impact it. A variation on this, peace studies (irenology), is an interdisciplinary effort aiming at the prevention, de-escalation, and solution of conflicts by peaceful means, thereby seeking "victory" for all parties involved in the conflict. This is in contrast to military studies, which has as its aim on the efficient attainment of victory in conflicts, primarily by violent means to the satisfaction of one or more, but not all, parties involved. Disciplines involved may include philosophy, political science, geography, economics, psychology, sociology, international relations, history, anthropology, religious studies, and gender studies, as well as a variety of others. Relevant sub-disciplines of such fields, such as peace economics, may be regarded as belonging to peace and conflict studies also. This establishes a power disparity between the conflict actors and the conflict resolution theorists/ practitioners, exacerbating the distance between the two groups and privileging the latter.

Published: March 2021

In this study, by using a new identity we establish some new Simpson type inequalities for differentiables–convex functions in the second sense. Various special cases have been studied in details. Also, in order to illustrate the efficient of our main results, some applications to special means and weighted Simpson quadrature formula are given. The obtained results generalize and refine certain known results. At the end, a brief conclusion is given as well.

Crack Growth Sensitivity to the Magnitude and Frequency of Load Fluctuation in Stage 1b of High-pH Stress Corrosion Cracking
Authors: Niazi Hamid , Nelson Greg , Lamborn Lyndon , Eadie Reg , Chen Weixing , Zhang Hao
Published: March 2021

Pipelines undergo sequential stages before failure caused by high-pH stress corrosion cracking. These sequential stages are the incubation stage, intergranular crack initiation (Stage 1a), crack evolution to provide the condition for mechanically driven crack growth (Stage 1b), sustainable mechanically driven crack propagation (Stage 2), and rapid crack propagation to failure (Stage 3). The crack propagation mechanisms in Stage 1b are composed of the nucleation and growth of secondary cracks on the free surface and crack coalescence of secondary cracks with one another and the primary crack. These mechanisms continue until the stress intensity factor (K) at the crack tip reaches a critical value, known as KISCC. This investigation took a novel approach to study Stage 1b in using precracked compact tension (CT) specimens. Using precracked specimens and maintaining K at less than KISCC provided an opportunity to study crack initiation on the surface of the specimen under plane stress conditions in the presence of a pre-existing crack. In the present work, the effects of cyclic loading characteristics on crack growth behavior during Stage 1b were studied. It was observed that the pre-existing cracks during Stage 1b led to the initiation of secondary cracks. The initiation of the secondary cracks at the crack tip depended on loading characteristics, i.e., the amplitude and frequency of load fluctuations. The secondary cracks at the crack tip can be classified into four categories based on their positions with respect to the primary crack. Low R-ratio cycles generated an evident cyclic plastic zone, where high density of intergranular cracks were formed. The higher the frequency of the low R-ratio cycles, the higher the density of the intergranular cracks forming in the cyclic plastic zone. The crack growth rate increased with an increase in either the amplitude or the frequency of the load fluctuations. The minimum and maximum crack growth rates were 8 × 10−9 mm/s and 4.2 × 10−7 mm/s, respectively, with the R-ratio varying between 0.2 and 0.9, frequency varying between 10−4 Hz and 5 × 10−2 Hz, and at a fixed stress intensity factor of 15 MPa√m. It was found that avoiding rapid and large load fluctuations slowed down crack geometry evolution and delayed the onset of Stage 2. The implication of these results for pipeline operators is that reducing internal pressure fluctuations by reducing the frequency and/or amplitude of the fluctuations can expand Stage 1 and increase the reliable lifetime of operating pipelines.
