Collaborative elicitation process for sustainable manufacturing: A novel evolution model of green technology innovation path selection of manufacturing enterprises under environmental regulation
Authors: Wang Manman , Yin Shi , Lian Shuai
Published: June 2022

Due to promote manufacturing enterprises to carry out green technology innovation practice smoothly, achieve the goal of energy conservation and emission reduction, and win green competitive advantage, this paper first divides the green technology innovation path into two types, namely internal independent R&D of green technology (IIGT) and external green technology introduction (EGTI), and analyzes the operation mechanism of these two types of paths. Secondly, a two-agent game model of different types of environmental regulation tools on the choice of green technology innovation path of manufacturing enterprises is constructed. To be sure, the manufacturing enterprises include the leader enterprise A and the follower enterprise B. It is assumed that the two groups of manufacturing enterprises produce the same products or provide the same services in the natural state without considering other influencing factors. Finally, stability analysis and numerical simulation are employed to compare and analyze the heterogeneous effects of different environmental regulation tools on the path selection of green technology innovation in manufacturing enterprises.The simulation shows that when the government adopts or does not adopt environmental regulation means, the system, leader enterprise A and follower enterprise B will eventually choose the path of IIGT or EGTI respectively after a long-term evolution process. However, the effects of subsidy for green technology innovation and carbon tax rate on the path selection of green technology innovation are different among the three parties. Specifically, when the government adopts the means of subsidy for green technology innovation, the leader enterprise A will actively choose the the path of IIGT earlier than the follower enterprise B. On the contrary, when the government adopts the means of carbon tax, the leader enterprise A will actively choose the the path of IIGT later than the follower enterprise B. The research of this paper is helpful to explore the green and sustainable development mode of China’s manufacturing industry under the dual constraints of environment and resources, and provides decision support for the relevant national departments to make relevant policies.

Introduction

There have been more than 425 million COVID-19 infections worldwide. Post-COVID illness has become a common, disabling complication of this infection. Therefore, it presents a significant challenge to global public health and economic activity.

Methods

Comprehensive clinical assessment (symptoms, WHO performance status, cognitive testing, CPET, lung function, high-resolution CT chest, CT pulmonary angiogram and cardiac MRI) of previously well, working-age adults in full-time employment was conducted to identify physical and neurocognitive deficits in those with severe or prolonged COVID-19 illness.

Results

205 consecutive patients, age 39 (IQR30.0–46.7) years, 84% male, were assessed 24 (IQR17.1–34.0) weeks after acute illness. 69% reported ≥3 ongoing symptoms. Shortness of breath (61%), fatigue (54%) and cognitive problems (47%) were the most frequent symptoms, 17% met criteria for anxiety and 24% depression. 67% remained below pre-COVID performance status at 24 weeks. One third of lung function tests were abnormal, (reduced lung volume and transfer factor, and obstructive spirometry). HRCT lung was clinically indicated in <50% of patients, with COVID-associated pathology found in 25% of these. In all but three HRCTs, changes were graded ‘mild’. There was an extremely low incidence of pulmonary thromboembolic disease or significant cardiac pathology. A specific, focal cognitive deficit was identified in those with ongoing symptoms of fatigue, poor concentration, poor memory, low mood, and anxiety. This was notably more common in patients managed in the community during their acute illness.

Conclusion

Despite low rates of residual cardiopulmonary pathology, in this cohort, with low rates of premorbid illness, there is a high burden of symptoms and failure to regain pre-COVID performance 6-months after acute illness. Cognitive assessment identified a specific deficit of the same magnitude as intoxication at the UK drink driving limit or the deterioration expected with 10 years ageing, which appears to contribute significantly to the symptomatology of long-COVID.

Published: June 2022

Background

It is unknown to what extent cancer drugs approved in Switzerland by the Swissmedic fulfil criteria of clinical benefit according to the European Society of Medical Oncology Magnitude of Clinical Benefit Scale version 1.1 (ESMO-MCBS), the American Society of Clinical Oncology Value Framework version 2 (ASCO-VF) and the Swiss OLUtool v2 (OLUtool).

Patients and methods

An electronic search identified studies that led to marketing authorisations in Switzerland 2010–2019. Studies were evaluated according to ESMO-MCBS, ASCO-VF and OLUtool. Substantial benefit for ESMO-MCBS, was defined as a grade A or B for (neo)adjuvant intent and 4 or 5 for palliative intent. For ASCO-VF and OLUtool clinical benefit was defined as score ≥45 and A or B, respectively. Concordance between the frameworks was calculated with Cohen’s Kappa (κ). Factors associated with clinical benefit were evaluated by logistic regression.

Results

In the study period, 48 drugs were approved for 92 evaluable indications, based on 100 studies. Ratings for ESMO-MCBS, ASCO-VF and OLUtool could be performed for 100, 86, and 97 studies, respectively. Overall, 39 (39%), 44 (51%), 45 (46%) of the studies showed substantial clinical benefit according to ESMO-MCBS v1.1, ASCO-VF, OLUtool criteria, respectively. There was fair concordance between ESMO-MCBS and ASCO-VF in the palliative setting (κ = 0.31, P = 0.004) and moderate concordance between ESMO-MCBS and OLUtool (κ = 0.41, P<0.001). There was no significant concordance between ASCO-VF and OLUtool (κ = 0.18, P = 0.12). Factors associated with substantial clinical benefit in multivariable analysis were HRQoL benefit reported as secondary outcome for ESMO-MCBS and the ASCO-VF and blinded studies for OLUtool.

Conclusions

At the time of approval, only around half of the trials supporting marketing authorisation of recently approved cancer drugs in Switzerland meet the criteria for substantial clinical benefit when evaluated with ESMO-MCBS, ASCO-VF or OLUtool. There was at best only moderate concordance between the grading systems.
The impact of economic policy uncertainty on corporate social responsibility: A new evidence from food industry in China
Authors: Su Fang , Song Nini , Shang Haiyang , Fahad Shah
Published: June 2022

The ability of the food industry to practice a high degree of corporate social responsibility is related to whether national food safety can be effectively guaranteed. By taking the food enterprises in China’s A-share listed companies from 2009–2018, this paper probes into the influence of China’s macroeconomic policy uncertainty on corporate social responsibility, and depicts the differencent impact of enterprise’s practice of social responsibility under government association and market association, respectively. The results firstly show that, the uncertainty of economic policy has a negative effect on the social responsibility of food enterprises, with a regression coefficient of -0.013. Secondly, nonstate-owned enterprises are more vulnerable to macroeconomic fluctuations in the practice of social responsibility. Thirdly, in the case of greater economic policy uncertainty, enterprises with stronger market connections in the food industry tend to be more conservative in their CSR. The above research results not only verify the path of transmission of economic policy uncertainty to corporate social responsibility, but also provide important ideas and references for improving the level of corporate social responsibility in the food industry and ensuring food safety.

Published: June 2022

The purpose of this study was to identify factors associated with the increase in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S1) protein and neutralizing antibody titer following SARS-CoV-2 vaccination. This observational study was conducted among healthcare workers working for a private hospital group in Fukushima Prefecture, Japan. Two blood samples were obtained from each participant. The first sample was obtained before the first dose of BNT162b2 (Pfizer-BioNTech) vaccine, and a second sample was obtained approximately 6 weeks later. Immunoglobulin G (IgG) antibody against the SARS-CoV-2 spike (S1) protein, immunoglobulin M (IgM) antibody against SARS-CoV-2 N-protein, and neutralizing activity were measured using the chemiluminescent immunoassay with iFlash 3000. A total of 231 healthcare workers who agreed to participate, and were negative for anti-SARS-CoV-2 IgM antibodies at enrollment, were included in the analysis. All participants had elevated IgG antibodies and neutralizing activity above the cutoff values. A total of 174 (75.3%) and 208 (90.0%) participants experienced adverse reactions after the first and second vaccine doses, respectively. Younger age, female sex, not taking immunosuppressive or antipyretic analgesic medication regularly, a lack of local adverse reactions after the first dose, and the presence of adverse reactions (fever, muscle, and joint pain) after the second dose were associated with higher IgG antibody titers and neutralizing activity. Intake of analgesic antipyretic for adverse reactions to vaccines was not significantly associated with antibody and neutralizing activity titer production. Immune responses after vaccination may differ among individuals, and continued countermeasures to prevent SARS-CoV-2 infection are vital.
Aportes centroamericanos para una pedagogía decolonial: María Isabel Carvajal y Berta Cáceres
Authors: Méndez Méndez José Mario
Published: June 2022

La costarricense María Isabel Carbajal y la hondureña Berta Cáceres trazaron –con su pensamiento y con su práctica socioeducativa– una ruta pedagógica que se caracteriza por hacerse cargo de la realidad centroamericana, de los conflictos sociales y de las luchas comunitarias.En ese camino de fidelidad a lo real, entendieron la educación como mediación liberadora y a la persona educadora como acompañante de procesos transformadores. Nos mostraron que los procesos educativos no son neutros, pues encarnan opciones –a veces dolorosas–, afectos, rechazos y deseos.Estas dos educadoras centroamericanas siguen incomodando a quienes se resisten a los cambios sociales y siguen esperanzando a quienes confían en la educación como mediación para la construcción de una sociedad más justa.
Un profesor universitario sin el graduado escolar: una experiencia sobre educación formal postfranquista, vivida en primera persona
Authors: Calvo Garcia Francisco
Published: June 2022

El sistema educativo de España ha pasado por enormes cambios epistemológicos y estructurales durante los últimos 70 años. En la finalización de la dictadura franquista y durante los primeros años de transición, las prácticas violentas a nivel físico en el contexto de la escuela se fueron reduciendo progresivamente, aunque el modelo educativo de los años ochenta y principios de los noventa heredó prácticas violentas a nivel psicológico cuyo impacto no se ha estudiado en demasía. Con la primera ley educativa postfranquista, se comenzó a vislumbrar un modelo pedagógico más inclusivo, acorde con las necesidades sociales de la época y generador de segundas oportunidades. Este artículo trata de un caso práctico real, redactado en primera persona, sobre las vivencias del autor a su paso por dos paradigmas contrapuestos del sistema educativo español entre los años ochenta y los años noventa. El objetivo es reflexionar sobre el impacto de la violencia psicológica en el rendimiento académico en una primera fase de escolarización y, por otro lado, sobre cómo pudo recuperar la confianza en el sistema educativo a partir de los vínculos emocionales establecidos en una propuesta pedagógica innovadora totalmente distinta. Finalmente, se reflexiona sobre algunos de los retos que la educación formal enfrenta en este momento histórico.

Este relato refere-se à experiência de telemonitoramento por equipes de saúde da família em uma unidade básica de saúde, entre março e dezembro de 2020. Devido a pandemia causada pelo novo coronavírus e com o intuito de evitar a sua propagação entre os usuários e equipe de saúde, foi iniciado atendimento à distância às pessoas com sintomas respiratórios, utilizando-se de ferramentas disponíveis na Unidade Básica de Saúde – UBS, como o telefone fixo. Na realização desses contatos percebeu-se, alguns problemas como: instalação de telefone fixo apenas na recepção, sendo esta, um espaço muito pequeno, falta de pontos telefônicos nas demais salas, demora no tempo de espera durante as chamadas telefônicas aos usuários e a pouca adesão dos usuários no atendimento das chamadas por telefone fixo. Diante desse incômodo, percebeu-se que essa comunicação poderia ser melhorada com outros recursos. Dessa forma, a equipe realizou reuniões para reorganizar o processo de trabalho, assim sendo foi doado um smartphone por um dos participantes, assim, o processo de trabalho foi reorganizado com a participação da equipe, que prestava atendimento por meio da plataforma WhatsApp bussines, assim sendo, foi possível restabelecer o acompanhamento dos casos suspeitos e situação de saúde dos sintomáticos respiratórios e dos familiares. Essa troca de mensagens por aplicativo, serviu como um canal importante de comunicação e diálogo, abrangendo mais do que mero monitoramento, além disso, este relato mostra o quanto é possível lançar mão de novas tecnologias associadas à gestão de informação, à vigilância sanitária, à gestão descentralizada e ao trabalho esperado de equipes de saúde da família.
Influence of sisal fibre modification on the microbial stability of poly(hydroxybutyrate-co-valerate): thermal analysis
Authors: Kittikorn Thorsak , Strömberg Emma , Ek Monica , Karlsson Sigbritt
Published: June 2022

The effect of modification of sisal fibre with propionic anhydride and vinyltrimethoxy silane on the microbiological stability of poly(hydroxybutyrate-co-valerate) (PHBV) was investigated. The effect of the coupling agent – PHBV grafted with maleic anhydride (PHBV-g-MA) was also investigated. The best adhesion at the interface was observed for propionylation of sisal fibre, which improved the thermal properties of the composites. Composites with modified sisal fibre were characterized by higher activation energy (155 kJ/mol), which is related to stronger interactions at the matrix-fibre interface. In the microbial growth test, all biocomposites showed a decrease in molecular weight due to enzymatic degradation by Aspergillus niger. The most resistant to microorganisms was the composite containing propionylated sisal fibre. DMTA and TGA also confirmed the highest microbiological stability of the composite with the addition of propionylated sisal fibre, as evidenced by the smallest change in the properties after the microbiological growth test. In contrast, PHBV-g-MA caused significant enzymatic degradation due to the presence of large amorphous regions.

This paper presents a structural analysis of various methods to produce bacterial cellulose (BC) from Nata de Coco (Acetobacter xyllinum). BC sheet, BC chem and BC mech powder were successfully prepared using oven drying, chemical and mechanical treatment. The X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and field emission scanning electron microscopy (FESEM) were used to analyze the structure of prepared BC. The structure of bacterial cellulose was compared with the structure of commercial microcrystalline cellulose (MCC) and cotton fabric. The XRD results showed that the BC sheet sample had the highest degree of crystallinity (81.76%) compared to cotton cellulose (75.73%). The crystallite size of cotton was larger than the BC sheet, with the value of 6.83 ηm and 4.55 ηm, respectively. The peaks in the FTIR spectra of all BC were comparable to the commercial MCC and cotton fabrics. FESEM images showed that the prepared BC sheet, BC mech, and BC chem had an almost similar structure like commercial MCC and cotton fabric. It was concluded that simple preparation of BC could be implemented and used for further BC preparation as reinforcement in polymer composites, especially in food packaging.

Published: June 2022

The influence of the natural Gongura roselle fiber on the tensile and flexural properties as well as on Shore D hardness of acrylonitrile-butadiene-styrene (ABS) and poly (lactic acid) (PLA) was investigated. The composites were printed in fused deposition modeling (FDM) 3D technique. The addition of natural fiber improved the mechanical properties of the tested composites, while the flexural strength, modulus and hardness were better in the case of ABS-based composite. Whereas, PLA-based composites showed higher tensile strength. The influence of the nozzle angle on the mechanical properties of the composites was also investigated. The best results have been obtained when using an angle of 0 °.
Emergency Remote Studio Teaching
Authors: Winters Tara
Published: June 2022

The creative arts use primarily visual, kinaesthetic and somatic modes that depend on face-to-face communication in contrast to many other university subjects which rely more heavily on the written word. The hands-on, practice-based nature of art education makes it perhaps one of the least transferrable subjects to a fully online model. What can be learnt, then, from the forced situation of teaching and supervising studio-based learning in a higher education context under COVID-19 conditions? This reflective essay draws on the writer’s experience as a Fine Arts lecturer involved in emergency remote teaching (ERT) of studio-based, visual arts courses during the 2020 academic year. Framed as a series of ‘fieldnotes’ it aims to capture those fleeting, yet significant, thoughts and reflections so easily lost once things quickly reach a level of ‘new normal’. Notes from the field include: the effects of the shifted social dynamic of online communications in a teaching and learning context; the challenges of the video call as a dialogic space for the studio critique; the impact of the more structured nature of online systems with regard to documenting and recording creative work-in-progress; and the affordances of the dynamic, multi-modal nature of the digital medium for working with contextual research material. Developed as a pedagogical perspective combining reflection-in-action and reflection-on-action I offer first-hand observations and discussion, socialised against relevant literature, as a contribution to urgent conversations on the shape of the future learning environment.
Those Who Have No Chains to Lose: Precarious Paid Teachers and Master Instructors
Authors: Yagan Ersin
Published: June 2022

The term "precariat" refers to a group of employees who work in non-permanent jobs and do not have a steady source of income. According to the literature, the situation of paid teachers and master trainers working in public formal and non-formal education institutions was investigated in this study. The research was conducted with ten paid instructors and ten master instructors who worked for hourly salaries in Istanbul's schools and public education centers. The content analysis method, which is one of the qualitative research methods, was used to conduct the research. The information was gathered using a semi-structured interview form and a face-to-face interview technique. As a result of the data analysis, it was found that paid teachers and master instructors acted as denizen citizens. Personnel and trade union rights were the most prominent themes among the participants. When the research findings are considered, it is possible to conclude that eliminating low-wage occupations and security concerns will increase the quality of paid teachers and master instructors, as well as the educational system as a whole.

Published: June 2022

As most of the developed societies are ageing, how to engage older consumers in advertising has become important to marketing communication practitioners. A qualitative study was conducted in March 2021 by interviewing a convenience sample of 20 persons aged 50 to 64 in China. Interviewees most often recalled celebrity endorsers who frequently appear in popular TV dramas. Source attractiveness was the main reason for recalling the celebrity endorsers. Source attractiveness, source credibility, and congruency with image of the brand, as well as moral qualities of celebrities were frequently reported as major factors that brands should consider when selecting an endorser. Interviewees perceived that credibility of endorsers was closely related to their moral behavior. Regarding advertising effect, interviewees perceived that advertisements with celebrity endorsement could enhance brand awareness, create positive feelings about the brand, and enhance purchase intention. Interviewees perceived that traditional celebrities enjoy a higher level of credibility and persistence of popularity than online influencers. The study discusses the theoretical implications for whether the main theories of celebrity endorsement are applicable to older people in China as well as the practical implications for marketing communications.

Coloring Things Together: Experiences of Leading Together as Pastor Couples in the Norwegian Pentecostal Movement
Authors: Åkerlund Truls , Smidsrød Åse-Miriam
Published: June 2022

This article focuses on the growing, yet under-researched, phenomenon of co-leadership in which spouses lead congregations together as pastor couples. The study addresses the topic from the perspective of organizational leadership, probing the experiences of leading together among pastor couples in the Norwegian Pentecostal movement. Systematic text condensation of in-depth interviews showed that the participants described co-leadership as all-encompassing and tension-filled, constantly having to balance private and professional concerns in addition to managing expectations from congregants and global church culture. Amidst these challenges, they described unity in diversity and a sense of being called to lead the church together.
Intercultural citizenship and the internationalisation of higher education: the role of English language teaching
Authors: Baker Will , Fang Fan (Gabriel)
Published: June 2022

The expanding internationalisation of higher education (HE) has resulted in the inte rcultural dimensions becoming a core aim of many institutions. This is frequently represented though the concept of intercultural or global citizenship with students expected to engage with academic, professional and social communities across multiple scales from the local to the global. The language though which both the internationalisation of HE and intercultural citizenships is expected to take place is often English, or more precisely ELF, epically in English medium education (EME). Therefore, given this key role for English, English language teaching (ELT) provides an ideal setting for developing intercultural citizenship education. However, at present, this is an under-researched area. To address this gap, this collection of short papers provides a snap shot of current thinking and research form ELF perspectives. We include reports on the development of intercultural citizenship through study abroad for university students from China, Japan and Thailand; the role of intercultural citizenship in pre-service teacher education in Turkey; and a discussion of the relationship between intercultural citizenship, identity, symbolic power and language in the ELT and EMI classroom.
When the unconventional becomes convention: epistemic stance in English as a lingua franca research articles
Authors: Shchemeleva Irina
Published: June 2022

In the last decade numerous studies have been published in the field of English as an academic lingua franca (academic ELF). The majority of them, however, are devoted to the speaking mode. The present paper investigates written academic ELF texts – research articles in the social sciences and humanities. It explores the ways in which L2 speakers express epistemic stance in their texts and analyzes ELF-specific non-conventional forms of epistemic stance expressions. I use data from the SciELF corpus (https://www2.helsinki.fi/en/researchgroups/english-as-a-lingua-franca-in-academic-settings/research/wrelfa-corpus/scielf-corpus), which is unique in that it allows the study of academic texts written by L2 speakers in their unedited form. To uncover whether non-conventional expressions are also used in published academic texts, and to gain a deeper understanding of the extent to which variability in language use is accepted in published texts, I use the Google Scholar database as a reference corpus. My analysis shows that L2 authors creatively exploit linguistic resources to express epistemic stance, demonstrating considerable variability in language use. Findings also indicate that some non-conventional expressions are found in published texts.
Calibration and analysis of the potable water network in the Al-Yarmouk region employing WaterGEMS and GIS
Authors: Abdulsamad Abdulrahman A. , Abdulrazzaq Khalid Adel
Published: June 2022

Water supply and distribution networks play an important role in our daily activities. They make a substantial contribution to public health by providing potable water for public consumption and non-potable applications such as firefighters and other purposes such as irrigation. This study used ArcMap 10.8 and WaterGEMS CONNECT Edition update 1 version to create a hydraulic network model to simulate the pipes’ network. Detailed network information, including pipe lengths, layouts, and diameters, was given by the Baghdad Water Department. The TUF-2000H Handheld digital ultrasonic flow meter has been used to measure the water flows in the network’s source nodes. In eight junctions, the model was calibrated by measuring the pressures using the Bourdon gauge at selected junctions. The analysis was based on the steady-state time at the average demand. The analysis results showed that the pressures in the network ranged from 8 to 21 m H2O with a correlation coefficient of 0.988, with a noticeable decrease in pressures in the distant pipes from the sources supplying water to the network. The velocity of the main pipes was within acceptable limits 0.5–2 m/s. While for the internal distribution network, it was noticed that there is an increase in velocity for the main pipes due to low consumption in the lateral pipes.
On necessary and sufficient conditions for the monogeneity of a certain class of polynomials
Authors: Jones Lenny
Published: June 2022

Letf(x) ∈ ℤ[x] be monic and irreducible over ℚ, with deg(f) =n. LetK= ℚ(θ), wheref(θ) = 0, and let ℤKdenote the ring of integers ofK. We sayf(x) ismonogenicif {1,θ,θ2, …,θn−1} is a basis for ℤK. Otherwise,f(x) is callednon-monogenic. In this article, we give necessary and sufficient conditions for a certain class of polynomials to be monogenic. Using these conditions allows us to generate infinite families of non-monogenic polynomials. In particular, for quadrinomials our results show that there exist infinitely many primesp≥ 3, and integerst≥ 1 coprime top, such thatf(x) =xp− 2ptxp−1+p2t2xp−2+ 1 is non-monogenic. Finally, we illustrate this situation with an explicit example.
Deep neural network enabled active metasurface embedded design

Published: June 2022

In this paper, we propose a deep learning approach for forward modeling and inverse design of photonic devices containing embedded active metasurface structures. In particular, we demonstrate that combining neural network design of metasurfaces with scattering matrix-based optimization significantly simplifies the computational overhead while facilitating accurate objective-driven design. As an example, we apply our approach to the design of a continuously tunable bandpass filter in the mid-wave infrared, featuring narrow passband (∼10 nm), high quality factors (Q-factors ∼ 102), and large out-of-band rejection (optical density ≥ 3). The design consists of an optical phase-change material Ge2Sb2Se4Te (GSST) metasurface atop a silicon heater sandwiched between two distributed Bragg reflectors (DBRs). The proposed design approach can be generalized to the modeling and inverse design of arbitrary response photonic devices incorporating active metasurfaces.
The Presence of the Past in Contemporary Russian Prose Fiction: A Comparative Reading of Guzel’ Iakhina and Sergei Lebedev
Authors: Lunde Ingunn
Published: June 2022

This article studies the poetics of historical reimagination in works by Guzel’ Iakhina and Sergei Lebedev, two contemporary Russian prose writers. The main tendencies in Russian official history politics and memory culture of the last decade form the backdrop for the study. I illustrate these tendencies by a case study analysis of the representation of Stalinist repressions in the history park Rossiia — moia istoriia (Russia — My History). The comparative reading of Iakhina’s and Lebedev’s novels seeks to determine the key poetic features of the two authors’ fictional treatment of the past, also assessing to what degree, and how, these treatments challenge, promote, or negotiate current official history politics and memory culture. The analysis discusses the two authors’ shared concerns but also reveals fundamental differences in their poetics. Whereas Iakhina’s fictional universe has distinct boundaries that confine the story to the time and space where it takes place, Lebedev’s novels deal with the past from the perspective of today. The contrasting narrative perspectives have implications for how the past is represented — or made present — and how the reader is drawn into the narrative.
An Interval Fracture Analysis Method for Cracked Structures with Unknown-But-Bounded Parameters
Authors: Li Feng , Li Hongfeng , Ren Chuanxin , Zhou Yichen
Published: June 2022

An interval fracture analysis method based on the Taylor expansion is presented to predict the stress intensity factor (SIF) bounds for cracked structures with unknown-but-bounded parameters. Traditional probabilistic fracture analysis requires numerous sample points, because large errors will occur when the probability density distribution function of the parameters cannot be described by sufficient sample points. In the present paper, the expression of the SIF crack structure is given using the quarter-point displacement method. Then, the interval expressions of mode-I and mode-II SIF are obtained using the Taylor expansion and the interval finite element method, and the upper and lower limits of an equivalent SIF (ESIF) are determined. Finally, the new method is analytically compared with the interval Monte Carlo method. Numerical examples show that the influence of load uncertainty considerably surpasses that of the dimension uncertainty. The mode-I SIF has a greater impact on the ESIF. As the uncertain level increases, the accuracy of the upper and lower limits of the ESIF calculated by the new method is maintained at a high level.

Ce texte est construit à partir des arguments des attendus de la fable de l’entrepreneuriat, dont la fablede la croissance, le magma des PME de la fable de l’entrepreneuriat et la fable de la confusion entre entrepreneuriat et dispositifs habilitants. Nous étudierons la maxime oubliée de la fable de l’entrepreneuriat, Réfléchir avant d’agir, au regard du point de vue de ce que sont un entrepreneur et l’entrepreneuriat. Nous nous pencherons sur l’incubation et les incubateurs, sur les facteurs de motivation entrepreneuriale à partir des théories du financement incitatif (push and pull), sur les profils de l’entrepreneur, sur l’accompagnement, sur l’entrepreneuriat genré ainsi que sur l’entrepreneuriat universitaire pour effectuer la démonstration associée à la maxime oubliée. Une conclusion abordera la synthèse des bases de l’économie de l’entreprendre en contexte africain.

This text is built on the arguments of the expectations of the entrepreneurship fable, namely the growth fable, the SME mixture of the entrepreneurship fable and the fable of the confusion between entrepreneurship and empowering mechanisms. We will investigate the forgotten maxim of the entrepreneurship fable, “Think before you act”, from the point of view of what an entrepreneur is and what entrepreneurship is. We will also analyze business incubation and incubators, entrepreneurial motivation factors using the push and pull funding theories, entrepreneur profiles, entrepreneurial support, gendered entrepreneurship and university entrepreneurship to complete the demonstration associated with the forgotten maxim. A conclusion will address the question of the foundations of entrepreneurship in the African context.

The purpose of this study was to evaluate, identify and categorize the level of mathematical literacy of class VII students at MTs Husnul Khotimah 2 Kuningan before and after the implementation of the Team Assisted Individualization (TAI) learning model assisted by e-modules. This research method is quantitative with One Group Pretest-Posttest design. The data collection technique used a mathematical literacy test for pretest and posttest with number content. While the data analysis technique used the average difference test (Paired Sample T-Test) and the Gain test. The results showed that based on the results of the average difference test, there were differences in scores before and after the application of the Team Assisted Individualization (TAI) model with the help of e-modules and the application of the TAI model could also improve mathematical literacy with an average score of each before and after the application of the model is 47.07 and 70.33 with categorization of improvement based on the Gain test after the application of the TAI model assisted by e-modules, namely 7 students of low improvement, 18 students of moderate improvement, and 5 students of high improvement and the average increase of students after the application of the model TAI assisted by e-module is 0.481 and is included in the moderate criteria. Thus, one way to improve students' mathematical literacy is to use the TAI learning model.

Mathematical communication skills are the ability to identify and write everyday problems into mathematical language. One way to improve mathematical communication skills is to apply Moodle-assisted CTL learning. This study is written to analyze and evaluate mathematical communication skills improvement of the students taught by moodle-assisted CTL learning model. The research design used is experimental research with Pre-Experimental Design. The samples of this research are students of class VIII A at SMP Negeri 22 Semarang. The research data is obtained using a mathematical communication ability test. The data analysis in this study are; (1) Right Side Proportion Test; (2) Average difference Test; (3) N-Gain Test. The results of data analysis in this study are interpreted as follows: (1) students' mathematical communication skills in Moodle-assisted CTL learning are classically complete (Z_count>Z_table; 1.66 > 1.64); (2) mathematical communication skills in CTL learning assisted by Moodle have completed the minimum completeness criteria (t_count>t_table; 5.55 > 1.72); (3) there is an average increase in students' mathematical communication skills between before being given Moodle-assisted CTL learning and after Moodle-assisted CTL learning with N-Gain of 0.57. So we can conclude that students' mathematical communication skills have improved during the application of the moodle-assisted model, and we can suggest that the moodle-assisted CTL learning model can be used to improve mathematical communication skills.

Radical religious understanding has become a horrendous phenomenon, because religion, especially Islam, does not teach radicalism or even terrorism. This study aims to (1) analyze the design of instruments for early detection, (2) analyze the characteristics of the standard’s instrument in the form of the level of instrument validity and (3) analyze the level of reliability on the instrument for early detection of terrorism in the name of jihad in students of SMA Negeri 2 Semarang. This research uses descriptive qualitative and quantitative research. The content validity of the instrument was tested by 3 experts. The statement items developed were tested on 30 respondents (small class) and 145 respondents (large class). Data was collected using interview techniques, documentation and questionnaires. The results of this study produced 45 standard instrument items for early detection of terrorism in the name of jihad in the form of a Likert scale of 1-4 and presented online using a google form. The results of validation by experts are that there are 14 items that are declared invalid or have an Aiken V index value of less than 0.3 so that these items must be discarded. The non-test instrument has an interrater reliability coefficient, a small class trial, and a large class trial, respectively, which is 0.88; 0.92; 0.91. There are 17 items that are invalid or less than the correlation coefficient rcount in the small class trial. Based on the large class trial, the final results of the valid items were 45 items with an r-count value greater than 0.1362 and a non-negative value. The results of the KMO in the field trial were 0.803 so that the instrument items could be analyzed further. The instrument is formed into 12 factors. The instrument developed is constructivly valid because it is able to explain the overall variation in the terrorism early detection instrument of 66.79%. The conclusion from this study is that the the non-test instrument in the form of a Likert scale. The characteristics standard’s instruments of early detection for terrorism in the name of jihad is constructivly valid and reliable.

Analysis of urgent problems, connected with the concept of identity, in particular the folklore significance, becomes nowadays the leitmotif of modern cultural-anthropological and ethnofolklore studies, determining the relevance of those aspects in Slavonic ethnology aimed at the thorough study of problems concerning national, regional, local identity, both on the theoretically-methodological and practical, social-cultural levels, enlisting wide European scientific experience. Taking into account modern expansion of the notion of folklore text to the scales of communication act and text of culture, as well as its contemporary functioning in the form of the folklorismus, it seems to be the most perspective to apply to the works in the field of Slavonic ethnology, folkloristics and cultural anthropology, where immaterial cultural heritage is considered in the context of cultural, identification factors of a certain region. Identity of a separate community is formed according to them. Such investigations have been carried out in the scientific centers of Bulgaria, Macedonia, Serbia. They have confirmed the fact, that the complex, polyfunctional and interdisciplinary trend in the study of traditional folk culture, especially folklore, still remains a relevant task of modern Slavistics.

Formulaicity is one of the basic folklore principles. It means the stereotypy of linguistic and semantic constructions, embedded into the poetic canon in one way or another. The researchers nominate these stable repeated elements in various ways, namely formulas, invariable phrases, themes, motifs, loci communes, traditional epithets, similes, metaphors, parallelisms, idioms, fixedverbal complexes, blocks. The article is aimed at the formulaicity studying as one of the typological universals of various folklore genres. Introductory or initial formulas, containing chronological instructions, spatial parameters, are distinguished according to the compositional significance, their place in the text. These are stable rhythmic verbal constructions characterized by recognizability and stereotipicity. They execute memory (mnemonic), utilitarian and aesthetic functions. Semantic and functional ranges of formulaicity are revealed in the article. They can consolidate significant ritual-based and meaning determining segments of the text, contribute to better content preservation. They are called the aesthetic marker used to define the folklore style of the genres. The object of the research includes the formulas types – medial, situated in the key elements of the compositional structure emphasizing the dignity of the master, strength, beauty, etc., request-formulas, warning formulas, formulas of the impossible. The wishes aimed at ensuring good harvest, health and well-being of a person belong to the final formulas. They are expressed often in an imperative form.
