Authors: Wei LongYun , Zhang Nan , Li Yang
Published: February 2023

With the rapid growth of China's national economy and urban construction, various factors make deep excavation engineering a challenging, high-risk and difficult geotechnical engineering technical subject. It plays an important role in concrete construction and has very high requirements for technology. In deep excavation engineering, in order to achieve the same supporting purpose, there are many alternative schemes, among which each scheme has its own characteristics. The choice of deep excavation support scheme is a complex multi-factor decision-making problem. Based on the idea of distance discriminant analysis theory, considering the principle of distance discriminant analysis method and the specific characteristics of deep excavation support scheme, this article tries to apply discriminant analysis method to the optimization research of deep excavation support scheme, so as to discuss the optimization design of deep excavation support project. It is hoped that the research in this article can further ensure the construction effect of building projects and provide some reference for similar projects.

Authors: Peng Can , Xiao Heng , Ou Kaiman
Published: February 2023

The significance of the used housing market to the stability of people's lives and social development is increasing, and the prediction of its prices is becoming a key concern for society. In this paper, BP neural network model is used to predict the price of second-hand properties. In view of the disadvantages of slow convergence and the tendency to obtain local optimal solutions, the BP neural network model's input layer is optimized by a genetic algorithm to speed up the convergence speed and accuracy of the BP neural network model. The experimental results show that the improved GA-BP neural network has high prediction accuracy, with RMSE and MAE of 398.72 and 170.18, respectively. The difference between the actual and predicted values is small, which can provide a more stable tool for predicting house prices in the second-hand property market and broaden a new channel for the practical application of GA-BP neural network.

Authors: Gao Rui
Published: February 2023

Absolute-value detector (AVD) is a fundamental arithmetic logic circuit widely applied in spike-sorting area. In this paper, a novel circuit design of a concise 4-bit AVD whose topology consists of a 2’s complement circuit and a 3-bit ripple carry adder (for comparison purpose), etc., with critical path designed to be as short as possible. Since the minimum energy consumption and the minimum delay cannot be guaranteed at the same time, critical path gate sizing is conducted. Using the method of logic effort and appropriately relaxing the delay requirements to 1.5 times the minimum value, a suitable voltage ranging from 0V to 1V is found to achieve the goal of minimum power consumption.

Authors: Yang Gengfu
Published: February 2023

4-bits Absolute Value Detector circuit is a very commonly used circuit design. As to simplify the internal circuit design to make the total number of stage lesser which provides a less critical path circuit delay. Generally, this paper used combination of static CMOS design and the path transistor circuit design to design our circuit. After we got the optimized design, we applied the logic effort calculation to calculate the minimum delay of the circuit and determined the specific gate sizing value for each logic component. The energy optimization can be obtained by increasing our delay and adjusting the power supply (VDD) value. Eventually, we sacrifice our delay a little bit to get a huge amount of energy reduction.

Authors: Li Yuanxun , Li Mingyu , Liu Bin , Zhang Yizhi
Published: February 2023

With the increase of multi-purpose equipment, how to determine the equipment application scheme is an important problem. Aiming at the optimization of equipment application scheme, this paper adopts the scheme optimization method based on AHP fuzzy comprehensive evaluation method. In this method, AHP method is used to distribute the weight of each evaluation index. On this basis, fuzzy comprehensive evaluation method is used to comprehensively evaluate the equipment application scheme, and finally the optimal design scheme is obtained. By applying this method to the evaluation of a certain type of equipment application scheme, the effectiveness of the method is verified. This method organically combines quantitative analysis and qualitative analysis, and requires less quantitative data information in the evaluation process. It can effectively solve the multi-level and multi-objective large-scale system optimization problem.

El núcleo duro del liderazgo en el contexto de las decisiones directivas. Los elementos generales que definen al líder
Authors: Acevedo Adolfo , Linares Martha , Cachay Orestes
Published: February 2023

En la formación del ingeniero industrial se considera el liderazgo en la profesión y en las tareas empresariales. El liderazgo visto inicialmente como un rasgo innato de la personalidad ha ido variando en su concepción y praxis, considerándolo un tema conductual, un asunto de procesos, influencia del contexto o contingencia. Los autores definen tantos estilos de liderazgo que podría considerarse una jungla caótica con conductas, decisiones, procesos, perfiles que son innatos, adquiridos, aprendidos o creados, conformando un puzzle complejo y de difícil integración. El objetivo del estudio es identificar los elementos relevantes que constituyen la clave del surgimiento del líder, independientemente de la profusión de teorías desarrolladas en diferentes ámbitos académicos. Entre los hallazgos se encuentra que el liderazgo surge en todo grupo humano, independientemente de su tamaño y propósito donde el grupo asume la decisión de otorgarle la facultad de liderar a una persona específica. Las discusiones se enfocan en determinar los elementos que determinan esta elección grupal, sean ambientales, de proceso, de crisis o de personas, y el grado de equilibrio en las decisiones entre el líder designado y los seguidores.
High-protein delivery in mechanically ventilated patients: A study protocol for a randomized trial
Authors: Boonyasurak Sumawadee , Promsin Panuwat
Published: February 2023

Background: Critically ill patients are at risk of malnutrition; thus, optimal nutrition delivery is a key treatment for better outcomes. Inadequate energy and protein intake increase rate of hospital-acquired infection, duration of mechanical ventilation and mortality. However, there is no clear consensus regarding optimal protein dose in mechanically ventilated patients. In this study, we aim to compare between the effect of high and usual protein delivery on clinical outcomes in this patient group.
Methods: This is a single-centered, open-labelled, parallel-group, randomized controlled study conducting in medical, surgical and trauma intensive care units (ICU) at a tertiary university hospital in Bangkok, Thailand. We plan to enroll 240 adult mechanically ventilated patients who are expected to require ventilator support for at least 3 days. The intervention group will be prescribed high protein dose (at least 1.5 g/kg/day) throughout ICU stay since day 4 until a maximum of 28 days, whereas the control group will be prescribed usual protein dose (1-1.3 g/kg/day). Nutrition is provided by enteral or parenteral route or both. The primary outcome is ventilator-free days at 28 days. The main secondary outcomes include the temporal change in muscle mass and SOFA score, rate of nosocomial infection and 28-day mortality.
Conclusion: The robust evidence whether delivering high protein in critically ill patients improves outcome is lacking. This randomized trial will examine the consequence of high protein delivery in ICU population.
‘Doing the same puzzle over and over again’: a qualitative analysis of feeling stuck in grief.
Authors: Poxon Lucy
Published: February 2023

2022 has witnessed a crescendo of controversial debate in grief and bereavement research, surrounding the inclusion of Prolonged Grief Disorder (PGD) in the revised Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V-TR). Criticisms of the inclusion of PGD focus on the potential for diagnosis narrowing the range of healthy functioning and any treatment gains associated with a PGD diagnosis being outweighed by the risk of pathologising individual differences and diversity in human behaviour (Ben-Zeev, Young & Corrigan, 2010). This qualitative research approaches ‘stuckness’ in grief from a non-pathologising, inductive and curious position that embodies the core, humanistic values of Counselling Psychology (Cooper, 2009). Four participants who reported feeling stuck in grief were interviewed and the resultant transcripts were analysed using Interpretative Phenomenological Analysis (IPA). The four superordinate themes: (‘Eclipsed by the deceased’; ‘The power in powerlessness’; ‘The double-edged sword of coping behaviours’ and ‘Living in Purgatory’) reveal novel insights into the significance and consequences of living with unresolved dilemmas of grieving. Findings support a meaning reconstruction approach to grief therapy and highlight the negative implications of holding a pathologising, time-limited, stage-based conceptualisation of grief. Implications for practice include combining person-centred therapy with targeted cognitive-behavioral grief interventions.
Attachment Anxiety and Covert Narcissistic Pangs as Reflected in Tennessee William’s The Glass Menagerie
Authors: M Ramesh Kumar , G Christopher
Published: February 2023

This paper aims to provide an interdisciplinary space for fruitful debate concerning psychoanalytical representations of attachment anxiety and the fear of abandonment of a covert narcissist within the ambit of narcissism, and its implications in artistic, literary, and health discourses. Researchers in psychiatric, clinical, developmental, personality, and social psychology are interested in the issue of narcissism since its resurgence has hit the world on a pandemic scale in the last few years. Despite the extensive research on the construct of narcissism conducted so far, one of its under-represented clinical subtypes, "covert narcissism," which is intrinsically intertwined with the fear of abandonment and attachment anxiety (Cramer, 2019) remains largely unexplored as opposed to its counterpart, grandiose narcissism. Extending this hypothesis, the primary objective of the current scholarly investigation is to examine the correlations underlying the maladaptive attachment anxiety and fear of abandonment that Amanda Wingfield, the female protagonist of Tennessee Williams's most autobiographical play, The Glass Menagerie, wrestles with in her interpersonal and intrapersonal relationships. The study's secondary purpose is to further scrutinize and unearth a slew of unconscious yet toxic expressions of covert narcissism that Amanda embodies in her machinations to remain in her 'secure base'.

Published: February 2023

This study evaluates the place of social media platforms (SMP) and their use patterns amongst Saudi EFL learners, their preferences, and academic impact at the Department of English and Translation of Qassim University, Saudi Arabia. The study uses a seven item closed-ended questionnaire to conduct a survey to gather the data from male students at the University. A total of 100 randomly chosen (male) students in the department of language and translation were given the questionnaires to answer. Analysis of data shows that most students judiciously utilise SMPs to meet their scholastic or academic demands, with YouTube and Facebook topping log-in time and diversity of use by EFL students. In addition, the use of SMPs helped significantly improve students’ capacity to contribute to information exchange and collaborative education, enhanced their academic standing and strengthened their reading and writing abilities. On an average, most students spend three hours a day on SMP. Among the positive impacts of SMP on students' global development included accessing and sharing updated information in an entertaining format. At the same time, some negative impacts reported were minimized interpersonal contact, non-academic use of the SMPs, and physical ailments (mainly vision centred) due to being glued to electronic devise for long durations of time. The current study demonstrates the efficacy of SMPs for academic purposes, which is a positive factor for their grades and academic competence and recommends that teachers engage their learners to use SMP for both entertainment and academics.

Published: February 2023

O vírus SARS-CoV-2, com os primeiros relatos surgidos em Wuhan, China, alastrou-se globalmente devido a sua facilidade de espalhar-se pelo ar. Tendo em vista sua grande capacidade de disseminação, a OMS declarou pandemia mundial uma vez que o distanciamento se tornou a medida de segurança mais viável. Autoridades estaduais e municipais foram responsáveis por implementar tais medidas. O objetivo deste trabalho foi analisar o comportamento preventivo e as medidas de segurança contra a Covid-19, utilizadas pelo comércio e pela população de uma cidade do agreste sergipano, caracterizada por ser um centro comercial da região com grande circulação de pessoas. Trata-se de uma pesquisa descritiva observacional, de caráter qualitativo. A coleta de dados foi realizada em ambientes abertos (feira livre) e em estabelecimentos fechados (supermercados) do comércio local. Observou-se que nos estabelecimentos privados houve maior cumprimento das medidas de segurança devido à alta fiscalização e preocupação com multas. Já na feira livre, foi observada a ausência da utilização de máscaras pela maioria dos passantes. O uso incorreto da máscara foi observado nas duas situações, provável causa do alto índice de casos de Covid-19 na cidade.  Estratégias de controle em feiras livres foram apresentadas. Pesquisadores alertam que vivemos a era das pandemias, assim faz-se necessário aprender com os erros e preparar a população para possíveis novas situações pandêmicas.
THE THREAT OF MOVING THE BRAZILIAN EMBASSY FROM TEL AVIV TO JERUSALEM: ANNOUNCEMENT, RETREAT, AND REPERCUSSIONS IN BRAZIL
Authors: Alzoubi Ahmad Sad
Published: February 2023

For many decades, the Brazilian State has supported the Palestinian position. In 2010, it recognised the Palestinian State within the 1967 borders. The situation drastically changed with former president Jair Bolsonaro’s rise to power. Bolsonaro openly pledged to Neo-Charismatic Evangelical denominations to transfer the Brazilian embassy from Tel Aviv to Jerusalem and unconditionally support the Israeli annexation of the Holy City at the expense of Palestinian rights.  Such a step would mean a historical breach from the Brazilian approach, according to which Jerusalem’s final status would be conditional on peace negotiations for a two-state solution. Bolsonaro’s administration retreated from actions yet pledged to transfer the Embassy. This study applies qualitative interviews and data collection as methodology. The author interviews three Brazilian solidarity activists challenging the current foreign policy of Brazil. Our goal is to understand why and which role (if any) Brazilian activists or institutions had in the government's retraction about the Embassy transfer. Were the pledges and ensuing waiver a personal decision or a conscious foreign policy? Jair Bolsonaro is a far-right, authoritarian politician with dictatorial proclivities. Bolsonaro himself and his restricted inner circle were responsible for the decision – although under intense pressure. It was not a government decision but a presidential one.

Investigating Teachers’ Perceptions of STEM Education in Private Elementary Schools in Abu Dhabi
Authors: Chaya Heba
Published: February 2023

One of the furthermost essential reforms in education is STEM (Science, Technology, Engineering, and Math) education. To implement STEM education effectively at the elementary level, the teachers must be well equipped to face the complicated web that enshrouds the STEM education field. Identifying teachers’ perceptions of STEM education is considered one of the ultimate significant processes that need to be considered by the STEM education stakeholders as the teachers’ STEM practices are highly influenced by their perceptions of STEM.

The purpose of this study was to investigate the teachers’ perceptions of STEM education in Abu Dhabi private elementary schools. The researcher conducted an empirical study with a mixed methods design to meet the purpose of the study. 75 STEM elementary teachers from different private schools in Abu Dhabi participated in this study via an online survey method. The instrument of this study was a teacher questionnaire which was adopted from the valid and reliable cross-sectional Vietnamese survey of Thi To Khuyen et al. (2020) based on their official permission.

The quantitative findings related to the teacher questionnaire revealed that 75% of the elementary teachers in STEM private schools in Abu Dhabi strongly understand what STEM education is and they strongly agreed that STEM competencies are extremely important. Yet, 50% of the teachers agreed that they find difficulties in implementing STEM education. Qualitative data related to the teacher questionnaire revealed that these difficulties were related specifically to the lack of STEM resources, the constraint of time, and the need for professional development.

This study is unique in the UAE as no studies up to the best of the researcher’s knowledge were conducted to investigate the teachers’ perceptions of STEM education in private elementary schools in Abu Dhabi. Hereafter, this study is significant by contributing to the STEM literature in the UAE. More, the results of the study are valuable in terms of stipulating implications for STEM elementary education program developers as teachers’ perceptions affect and shape their decisions in STEM field.
Cervantes y Avellaneda (1616-2016): presunciones y certidumbres
Authors: Martín Jiménez Alfonso
Published: February 2023

En el año 2016, en el que conmemoramos los cuatrocientos años transcurridos desde la muerte de Cervantes, la mayor parte de la crítica sigue sin asimilar cómo se desarrolló la disputa literaria entre Cervantes y Avellaneda. En este trabajo se intenta explicar la manera en que se produjo esa disputa, mostrando la negativa influencia que ha tenido la tradición heredada de la Historia literaria romántica y positivista, la cual ha impedido reconocer dos aspectos esenciales: que toda la segunda parte del Quijote de Cervantes constituye una imitación del Quijote de Avellaneda, y que el propio Cervantes identificaba a Avellaneda con el aragonés Jerónimo de Pasamonte.
