DISCOURSE AND DISQUALIFICATION
Authors: Thau Tena 
Published: May 2021

Abstract
A commonly expressed sentiment in contemporary political discourse is that bigotry should be disqualifying. In this paper, I consider how this sentiment might be formulated into a more precise moral principle. After identifying problems with several candidate formulations, I suggest the version of the principle that best captures the expression’s intended meaning. I then consider the principle’s justifiability, its value as a decision-procedure, and its power as a discursive act.
Evaluación del impacto de la infraestructura física educativa en la educación
Authors: Pacheco Martínez Nancy Jacqueline 
Published: May 2021

Esta investigación tuvo como objetivo evaluar las condiciones y el estado actual de la infraestructura física educativa (INFE) y su efecto en la educación a nivel preescolar. Para ello, se concretó un estudio de caso en el que se incluyeron los jardines de niños públicos ubicados en la región central de la República mexicana. Las preguntas formuladas fueron las siguientes: ¿qué relación existe entre la INFE y la educación que en su interior se imparte?, ¿cuánto impacta el estado actual de la INFE en la eficacia de la educación? y ¿qué papel desempeña el cumplimiento normativo de la INFE en dicha relación e impacto en la educación? El estudio desarrollado fue de tipo mixto, ya que se utilizaron técnicas cuantitativas, cualitativas y de carácter multidisplinario. Los instrumentos utilizados fueron la selección de la muestra representativa a través de un proceso aleatorio, la observación no participativa, el levantamiento físico de datos, el soporte fotográfico y el análisis de cumplimiento normativo con base en lo que señalan la Ley General de Educación (LGE, 2019), los reglamentos de construcciones de cada uno de los estados evaluados, las normas oficiales mexicanas de tipo obligatorio y de observancia voluntaria, así como los lineamientos de la Secretaría de Educación Pública (SEP,1921), Manuales de Protección Civil e informes de la Organización para la Organización para la Cooperación y el Desarrollo Económicos (OCDE, 1961).Los resultados indican que el estado físico y el emplazamiento de los centros educativos inciden directamente en el desempeño de los estudiantes, por lo que se debe gestionar la adecuada supervisión por parte de las autoridades y de los mismos usuarios (docentes, administrativos y personal), quienes deben identificar los riesgos y las condiciones en las que se prestan los servicios de educación a nivel de preescolar en México. Asimismo, se debe fomentar la mejora continua de la calidad de la INFE para consolidar el derecho a la educación de todos los niños y las niñas de este país.

Published: May 2021

Aims
To assess whether frailty or reduced physical performance status may have an impact on clinical outcomes after pacemaker implantation in aging patients.

Methods
A prospective cohort of patients aged more than 70 years, admitted to the hospital for pacemaker implantation, was enrolled. Patients were evaluated with the Short Physical Performance Battery (SPPB) and Handgrip Strength Test at hospital discharge and at 1 year. Overall mortality was the primary study endpoint.

Results
Out of the 119 patients, the majority (71%) of patients had reduced physical performance (defined by an SPPB score <10 points). After a median follow-up of 46 months, the mortality was 31% of the population. SPPB value at discharge predicted death even after adjusting for pertinent confounders (adjusted hazard ratio 0.91, 95% confidence interval (CI) 0.84–0.99, P = 0.02). Patients with a poorer SPPB score at discharge (SPPB 0–3) had also an increased risk of death or rehospitalization at 1 year compared with patients with highest SPPB score (odds ratio OR 4.05, 95% CI 1–16.6).

Conclusion
Reduced physical performance is associated with increased mortality in aging patients with bradyarrhythmia requiring pacemaker implantation. The identification of patients with poor SPPB may tailor specific interventions to improve physical performance and outcomes after pacemaker implantation.

Published: May 2021

Summary

Aim: The aim of this study is to present the results of the evaluation of the Preparatory Swimming Intervention Programme for Children with Autism Spectrum Disorder (PAS).

Methods: The study used a method of participating observation by which evaluators diagnosed swimming skills. The diagnostic tool was Štochl’s scale of swimming skills evaluation (Štochl et al. 2005). A nonparametric sign test was chosen for the analysis of the results.

Results: The results of the sign test showed that all probands studied had an overall improvement in all skills between measurements 1 and 2, 3 and 4 and also 1 and 4. In a comparison of individual probands, swimming skills improved between the 1st and 2nd measurements in two of them. The third proband achieved the greatest improvement between the 3rd and 4th measurements, the fourth between the 1st and 4th measurements. The fifth proband did not achieve a statistically significant improvement in the acquisition of swimming skills.

Conclusions: The results of this study show that for the area of preparatory swimming lessons for children with PAS, it is possible to use the Štochl scale (Štochl 2002) for diagnosing swimming skills, thus enabling quantitative data to monitor the level of acquired swimming skills in these individuals.
Preliminary Design for Segmental Joint of Precast Tunnel Liner
Authors: Pethrung Sirichai , Teachavorasinskun Supot , Keawsawasvong Suraparb 
Published: May 2021

Abstract
Responses of the segmental tunnel liner to external forces are primarily dependent on complicated interactions among construction process, soil structural interactions, segmental (longitudinal) joint characteristic etc. However, most proposed liner’s design procedures and recommendations are basically empirical and experience based, especially when the roles of tunnel joint are concerned. In the present study, a preliminary design calculation for the segmental joint with consideration of three practical conditions was proposed. The method adopts two main assumptions; the stiffness reduction factor and simplified pre-stressed concrete blocks, so that the flexural capacity of the segmental joint and its interactions to the main reinforced concrete segment body can be designated. Calculation examples are given for three most probable cases, namely, 1) the unbolted joint without joint opening, 2) the bolted joint without joint opening and 3) the unbolted segmental joint with allowing joint opening. Based on these calculations, the required compressive strength of concrete, thickness of liner, steel reinforcement, bolts and number of segments of the liner could be specified. The proposed method could well provide an engineer a tool to determine the initial joint configuration and its interaction to the overall tunnel lining.

Stiffness of Concrete-Filled Thin-Walled Steel Tubular Slender Columns
Authors: Bahrami Alireza , Mahmoudi Kouhi Ali 
Published: May 2021

Abstract
Concrete-filled thin-walled steel tubular slender columns are studied in this paper to evaluate their stiffness. The slender columns have various steel tube thicknesses, length/diameter (width) ratios, and concrete compressive strengths. The columns are loaded by axial and eccentric loads. Two experimental tests of the slender and stub columns are described. Also, the finite element software ABAQUS is utilised to simulate and analyse the columns. The tested columns are simulated taking into account all their features in the tests to verify the simulation of the columns. The simulation results are compared with the tests results which reveal that good agreements exist between them. Thus, the proposed simulation method of the columns is verified. In order to assess the stiffness of the columns under different conditions, various load eccentricities (0 mm, 25 mm, and 50 mm), cross-sectional configurations (circular, rectangular, and square), and steel tube thicknesses (2 mm, 3.35 mm, and 5 mm) are adopted for the developed columns. The columns are simulated and analysed based on the verified simulation method considering the mentioned conditions. As a conclusion, the stiffness of the columns is generally reduced by the increase of the load eccentricity from 0 mm to 25 mm and 50 mm. Further, more uniform distribution of the stiffness is witnessed for the columns with lower eccentricities. In addition, the enhancement of the load eccentricity increased the reduction slope of the stiffness graph for the columns. Although the initial stiffness of the circular column is slightly lower than the rectangular and square columns, the stiffness has more uniform distribution which is preferred. Larger stiffness is achieved for the columns by increasing the steel tube thickness from 2 mm to 3.35 mm and 5 mm.
Numerical Analysis of Corrosion Reinforcements in Fibrous Concrete Beams
Authors: Taqi Faten Y. , Mashrei Mohammed A. , Oleiwi Hayder M. 
Published: May 2021

Abstract
This paper offers a finite element method (FEM) to simulate the behavior of steel fiber reinforced concrete (SFRC) beams with corrosion of the longitudinal reinforcement using the ABAQUS package. This work was undertaken with the concrete damaged plasticity model (CDP). The expansion of corrosion product was utilized to represent the steel-concrete boundary to study the behavior of SFRC beams. Three beams with three volume fractions of steel fiber (0.8 %, 1.2 %, and 1.8 %) and three reinforced concrete (RC) beams with and without stirrups were created and tested under four-point loading to assess the shear capacity of beams. Corrosion of rebars at one of the RC beams that does not contain shear reinforcements will be studied. The crack patterns and load deflections of these beams were compared with experimental results found by the authors. The conclusions of this analysis will be valuable in considering the structural behavior of SFRC structures with uniform steel bar corrosion using FEM. Analytical results showed that the suggested model is qualified in better simulation and in accuracy of numerical and experimental results. The differences between analytical and experimental results were less than 8 % for load carrying capacity and 14 % for deflection; these differences are also satisfactory within the limits of the engineering conclusion.

Authors: Sahi Alaa Mohammed , Ali Mohammed Salih Abd 
Published: May 2021

Abstract
This paper was focused on the investigating on the behavior of hollow slender reinforced concrete columns subjected to the axial loads. A total of seven specimens were designed as slender reinforced columns and these were divided into two groups. Each column is symmetrical and had a rectangular cross section of 140 × 80 mm and 2000 mm in length. The column was reinforced by 6Ø6mm for longitudinal reinforcement and Ø6@6 mm bars were used for transverse reinforcement ties. The effect of strengthening by CFRP sheet on the buckling of column, eccentricity 20, 40 and 120 mm and opening shape were studied. The results showed that the strengthened columns by CFRP caused an in the ultimate load CFRP were 26.3 % and 76.3 % for strengthened lengths of L/4 and L respectively compared with the un-strengthened column. The ultimate load of columns is reduced with existing the load eccentricity and amount of losses in strength increased with increasing the eccentricity. Also, it was found the hollow columns having circular holes had better performance compared to hollow columns having rectangular hole
Compressive Strengths of Pavement Recycling Materials and New Approach for Cement Content Determination
Authors: Noulmanee Amorndech , Prongmanee Nutthachai , Pukdee Wannapa , Singhan Pattarapong 
Published: May 2021

Abstract
This research investigated the compressive strengths of cement treated with three types of aggregates (lateritic soil; crushed rock-blended reclaimed asphalt pavement; and a mixture of crushed rock, reclaimed asphalt pavement and lateritic soil). The strength was evaluated through a series of unconfined compression tests in the laboratory. Then, the test results were analyzed using statistical analysis. The results and analysis indicated that the strength of the cement-treated coarse-grained materials was controlled by the plasticity index and the water to cement ratio. Base on the results and analysis, this research developed a new approach for cement content determination. In addition, the proposed method should be useful for determining the proper cement content, as it requires less time and a smaller number of tests by using only two trials. A practical method to evaluate the cement content is thoroughly explained and verified in this study.
Stimuli contributing to local property taxation – with the focus on spatial effects of industry and functional urban areas
Authors: Zdražil Pavel , Pernica Bohuslav 
Published: May 2021

Abstract
In this study, we argue that a historical background of the region matters in tax mimicking and yardstick competition as a matter of principle. We seek to determine factors supporting the policy of the high local property tax in the Czech Republic. Based on the statistical and spatial data of 6,258 municipalities between 2009 and 2019, the results show that the municipalities burdened by large industrial facilities, as well as municipalities in the functional urban areas (FUAs), apply the policy of higher property taxation twice frequently than the rest. On the other hand, the industrial stimuli keep enfeebling after 2010, and the number of local governments preferring high property taxation is variegated across different FUAs. The causal analysis based on Granger's approach concludes an existence of cumulative effects of both industry and the FUAs, which push the municipalities with large industrial facilities located within an FUA to increase the property taxes. From the mimicking point of view, we found that mimicking policy is an important phenomenon among the municipalities of Czech Republic; however, it has different impacts on both stimuli (Industry and FUA). The analysis suggests that it rather incites the municipalities within the FUA to increase the local property taxes.
Light Fidelity (Li-Fi) overview and investigation into connection speed
Authors: Sharma Mithun , Sharma Shilpi 
Published: May 2021

Abstract
The overarching aim was to reduce the frequency of connection failures that occur due to the connection speed and reliability, and identify, characterise and optimise the key process input variables (KPIVs). An experimental research approach with an inbuilt planned manipulation to one or more variables in the experimental data set was adopted. Key elements of the Six-Sigma methodology were applied to resolve the issue of high failures due to connection speed and reliability between two Li-Fi transceivers. KPIVs were successfully identified, characterised and optimised to implement a permanent corrective action to ensure a reduction in connection failures from 17% to 0%. The alignment between two Li-Fi transceivers along with Li-Fi cut-out was found to be critical in achieving good connection speed and reliability. The interference due to ambient visible spectrum lighting found to be statistically insignificant. This study explored the application and benefits of accessible wireless data communication technologies. Moreover, it sheds light on the probable factors that may influence Li-Fi connection speed and areas for future research. The current research provides a Six-Sigma based solution to high connection failure rates while using an infrared-based Li-Fi transceiver. Results also offer insights into the analytical tools that were found to be effective during the problem-solving process.
Research insights: Global mobility in a post-covid world1
Authors: Collings David G , Sheeran Ruthanna 
Published: May 2021

Abstract
How multinational enterprises staff their global operations has been a key question for researchers in international human resource management (IHRM) for a number of decades. It is widely recognised that getting staffing right on the global scale is key in enabling multinational enterprises (MNEs) to deliver on their strategic objectives. However the landscape of global staffing has been evolving considerably over recent decades with a much more complex landscape of global mobility emerging. The COVID-19 pandemic poses a significant challenge for the future of global mobility and amplifies a number of trends already challenging our understanding of global staffing arrangements. In this paper, we reflect on these challenges and the likely future for global mobility. We also identify some critical areas of focus for scholars in researching global mobility moving forward.
A New Citation Recommendation Strategy Based on Term Functions in Related Studies Section
Authors: Chen Haihua 
Published: May 2021

Abstract

Purpose
Researchers frequently encounter the following problems when writing scientific articles: (1) Selecting appropriate citations to support the research idea is challenging. (2) The literature review is not conducted extensively, which leads to working on a research problem that others have well addressed. The study focuses on citation recommendation in the related studies section by applying the term function of a citation context, potentially improving the efficiency of writing a literature review.

Design/methodology/approach
We present nine term functions with three newly created and six identified from existing literature. Using these term functions as labels, we annotate 531 research papers in three topics to evaluate our proposed recommendation strategy. BM25 and Word2vec with VSM are implemented as the baseline models for the recommendation. Then the term function information is applied to enhance the performance.

Findings
The experiments show that the term function-based methods outperform the baseline methods regarding the recall, precision, and F1-score measurement, demonstrating that term functions are useful in identifying valuable citations.

Research limitations
The dataset is insufficient due to the complexity of annotating citation functions for paragraphs in the related studies section. More recent deep learning models should be performed to future validate the proposed approach.

Practical implications
The citation recommendation strategy can be helpful for valuable citation discovery, semantic scientific retrieval, and automatic literature review generation.

Originality/value
The proposed citation function-based citation recommendation can generate intuitive explanations of the results for users, improving the transparency, persuasiveness, and effectiveness of recommender systems.
Di bụ ugwu nwanyị (Husband is the dignity of a woman): Reimagining the Validity of an Igbo Aphorism in Contemporary Society
Authors: Wariboko Onyinyechi Priscilla Christian , Mbonu Caroline N. 
Published: May 2021

Abstract
Cultural aphorisms tend to sustain gender disparity. There are certain cultural expressions which tend to sustain gender disparity and oppression among the Igbo of Nigeria. One of such is di bụ ugwu nwanyị, literally translated ‘husband is a woman’s dignity’. This Igbo maxim tends to foster gendered marginalization and oppression in contemporary Igboland. The saying reinforces the status of the husband as requisite for the visibility and pride of the woman. Perhaps this may explain why some marital issues such as husband infidelity, wife-battering, are culturally underplayed for protection of the man. Thus women are forced to endure abuses in their marriages. There exist a plethora of other gender related issues that are rooted in the di bụ ugwu nwanyị metaphor. This paper engages the implications of this Igbo cultural expression amidst the advocacy of gender justice and inclusivity in Igbo land. As qualitative study that adopts the phenomenological approach, this paper, draws insight from interviews, observations, oral histories and extant Igbo literature. Akachi Ezeigbo’s snail-sense feminism and Obioma Nnaemeka’s negofeminism undergird the theoretical framework. The paper advocates for the obliteration, or reinterpretation of di bụ ugwu nwanyị that honours dignity for gender equity and inclusivity so as to valorize the status of women in Igboland.
