Published: November 2023

Model epidemik SIRV merupakan salah satu model epidemik yang merepresentasikan penyebaran penyakit menular pada empat kompartemen susceptible, infected, recovered dan vaccinated. Pada penelitian ini, model SIRV digunakan untuk mempelajari dinamika penyebaran penyakit COVID-19 dengan dua tahapan vaksinasi, yakni vaksinasi tahap 1 dan vaksinasi tahap 2. Analisis model dilakukan dengan menentukan bilangan reproduksi dasar, selanjutnya menentukan peluang transisi dan peluang terjadinya wabah dengan pendekatan stokastik Continuous-time Markov Chain (CTMC). Simulasi dilakukan untuk melihat pengaruh parameter laju vaksinasi tahap 1, laju penurunan efektivitas vaksin tahap 2 dan laju efektivitas pengobatan/treatment terhadap dinamika populasi. Hasil simulasi menunjukkan dengan laju vaksinasi sebesar dapat menyebabkan berkurangnya jumlah individu rentan dan terinfeksi. Adapun tingkat efektivitas vaksin sebesar efektif mengurangi jumlah individu yang terinfeksi. Selanjutnya pemberian pengobatan/treatment diperlukan sebanyak per hari untuk mencegah meningkatnya kembali kasus infeksi agar penyebaran COVID-19 dapat menghilang dari populasi.

Published: November 2023

Abstract
This review is an attempt to explore the challenges that need to be addressed to fully utilize the potential of ceramic-based functionally graded cutting tools (FGCTs). The various aspects covered in the review include the most recent experimental and numerical work related to FGCTs, the current research trends and the need for these tools, the identification of potential material combinations, synthesis techniques and their limitations, and finally a presentation of the most recent work. To find general tribological performance, various wear mechanisms involved in the cutting process are explored. Some recent experimental and numerical works related to the self-lubricating phase in functionally graded structure and the need for self-lubricating ceramic tools, identifying potential high-temperature solid lubricants, and their limitations are also discussed. More recent and dominating fabrication methods are also discussed in detail along with a brief review of some promising methods. The implementation of numerical modeling and computational frameworks validated through experiments is found to lead to the design and development of cost-effective and efficient FGCTs. Finally, some research gaps are identified and future directions for innovative FGCT materials are proposed.
FERTILITY PRESERVATION: Exploring the complexities of posthumous reproduction in fertility preservation for oncology patients with poor prognosis
Authors: Polyakov Alex , Rozen Genia 
Published: November 2023

The field of fertility preservation (FP) for oncology patients has evolved significantly in recent years, offering new possibilities for individuals with life-threatening illnesses. We commend Jones et al. for their comprehensive ethical review of offering FP to patients with poor prognoses, acknowledging the potential benefits that it may bring. ‘Poor prognosis’ in this context implies a high likelihood of death due to cancer progression. We highlight the importance of considering posthumous reproduction, involving the use of cryopreserved gametes or embryos to conceive a child after one or both partners have passed away, a topic briefly mentioned by Jones et al. Posthumous reproduction raises complex ethical, logistical, and legal questions. Distinctions between cryopreserved sperm and oocytes are discussed, with each scenario presenting unique challenges. The article also examines the complexities faced by same-sex couples in posthumous reproduction, addressing issues related to donor selection, legal parentage, and rights. Legal and regulatory aspects play a crucial role, including obtaining clear and legally valid consent, defining parental rights, navigating surrogacy laws, and addressing inheritance and estate planning. Ethical dilemmas require healthcare professionals to ensure informed decision-making, consider psychological impacts, and offer information on alternative family-building options.

Lay summary
Cancer treatments can have a negative impact on a person’s ability to have children, and some cancer survivors may end up being unable to conceive. Fortunately, there are currently available technologies that can help preserve fertility for these patients. These options include freezing eggs or sperm before starting cancer treatment. For patients who have been diagnosed with cancer and have a poor prognosis, meaning they are not likely to survive their illness, it is crucial to think about what happens to their frozen eggs and sperm in case of their death. This process of conceiving a child after someone's passing is known as ‘posthumous reproduction’. In our article, we explore the ethical, legal, and logistical challenges that the surviving partners of patients who may not live long enough to have a child with their frozen eggs or sperm might face. We pay particular attention to same-sex couples because their surviving partners often encounter more obstacles. In some countries, posthumous reproduction in these circumstances is even prohibited by law. There is a significant variation in the regulations related to posthumous reproduction, both between different countries and within individual countries. These differences need to be carefully considered when healthcare professionals counsel patients and their family members.

As an ecosystem, the mangrove ecosystem serves various purposes. The objectives of this study are to (1) identify the community structure of the important value index; and (2) evaluate the importance of the mangrove species diversity index in Pulias Bay in Ogodeide District, Tolitoli Regency. The study was conducted in 2021 using a quantitative descriptive methodology and survey method. The number of discovered species will be used to establish the species composition. The structure of the mangrove communities is being evaluated by calculating the relative density (RD) and frequency (FR). The data is tabulated to calculate the Important Value Index (IVI) value according to the Shannon-Wiener formula. There were 18 different species of mangroves discovered, including Rhizophora apiculata, Rh. mucronata, Rh. stylosa, Bruguiera parviflora, B. gymnorrhiza, Ceriops tagal, C. decandra, Sonneratia alba, S. caseolaris, S. ovata, Avicennia lanata, Xylocarpus moluccensis, Acrostichum aureum, Nypa fruticans, and Pemphis acidula. The Rhizophoraceae family predominated at each observation station, according to the findings of the vegetation analysis. Meanwhile the most rarely found species of mangrove were Acrostichum aureum, Sonneratia casiolaris, and Xylocarpus moluccensis, each with two specimens. The community structure reveals that X. moluccensis has the lowest IVI value of 12.7%, while Rhizophora mucronata has an IVI value of 101.3%. The mangrove Diversity Index (H') has a value of 2.48 and meets the standards for moderate diversity. Physical and chemical parameter measurements often indicate that the four stations or sites where the data was collected have similar conditions. Interestingly, we also found Avicennia lanata, a mangrove species that falls under the Vulnerable category. The collected information can be used to manage the mangrove forest in Pulias Bay in the Ogodeide Sub-District of the Tolitoli Regency and serve as a database for efforts to conserve mangroves and mitigate the effects of global warming.
Rekonstruksi Ideologi Superioritas Laki-Laki sebagai Penerima Wahyu (Analisis kata Rijalan pada QS. al-Anbiya' ayat 7 dengan Metode Ma’na Cum Maghza)
Authors: Akmal Saiful 
Published: November 2023

Previous interpretation of QS. al-Anbiya’ ayat 7 states that this verse is the argument that the messenger is only from men. However, it turns out that the word rijāl in QS. al-Anbiya’ ayat 7 there are indications of the meaning of women which is correlated with rijāl in other verses in the Koran. This shows that there are differences in interpreting interpretations depending on the interpreter's period. This study aims to examine the historical meaning, historical significance, and contemporary dynamic significance of QS. al-Anbiya’ ayat 7 to find relevant and progressive meanings to the present. This research was assessed using qualitative methods. literature review comes from data sources related to research with the ma'nā cum magzā approach theory. This theory was chosen because it has a structured and comprehensive work tool in offering interpretations of the Koran, because it has united classical science with multidisciplinary knowledge. This research got the result that QS. al-Anbiya’ ayat 7 actually does not focus on the issue of apostolic identity, but this verse indicates a connection with the statement of the Quraysh who doubted the Prophet Muhammad SAW as a messenger, then, in terms of historical significance, the message of the verse is an affirmation that the Prophet Muhammad SAW receiving revelation and in terms of contemporary dynamic significance reveals the importance of having competence in preaching which includes several strategies to approach aspects of sociology, psychology, culture and the wise command to ask scientific professionals who are experts in their fields.
Systemic tools integration to fight fake news from a posthumanist perspective
Authors: Buzato Marcelo El Khouri 
Published: November 2023

A theoretical-practical framework is proposed for an understanding of fake news stories from an interdisciplinary, ecological and posthumanist perspective. Key elements of three systemic approaches to meaning are integrated that allow for a symmetrical account of human and non-human agencies in fake news as a phenomenon. The findings are descriptioons of (1) fake news as systemic material-semiotic activity that emerges from algorithmic capture of human emotion and social-discursive degrees of freedom; how pre-conscious/emotional triggers can be hacked by informational patterns in fake news pieces; an “ontological syntax” of truthiness and falseness across institutional agencies in fake-news activity.
A ‘erosão do solo’ descrita em uma notícia: análise discursiva sobre a produção de sentidos envolvendo o ambiente rural
Authors: Maio Ana Maria Dantas de , Silva Marcelo Pereira da 
Published: November 2023

A Análise de Discurso (AD) de linha francesa e a Análise Crítica de Discurso (ACD) fundamentam este estudo, que examina um enunciado jornalístico sobre os efeitos da erosão do solo na produção agrícola. A intenção é investigar como uma notícia sobre um problema típico do universo rural e/ou ambiental produz sentidos para interlocutores sem vínculos com o agronegócio. O enunciado apresenta sinais de polifonia, silenciamento e didaticidade que demarcam as condições de produção do texto, identificam endo e exogrupos, além de determinar uma linha de leitura, entre outras possíveis. A análise conclui que esse discurso não conecta o problema da degradação do solo ao consumidor final. O sentido é interrompido no elo da produção rural, como se os efeitos da degradação do solo sofressem uma descontinuidade, sem afetar itens que são consumidos por habitantes urbanos.

O presente trabalho tem como objetivo analisar o Plano Diretor Participativo do Município de Petrolina (PE), enquanto política de desenvolvimento local, e seu diálogo com os Objetivos de Desenvolvimento Sustentável (ODS) presentes na Agenda 2030 com vistas ao alcance do desenvolvimento territorial sustentável. Por meio de estudo qualitativo de caráter bibliográfico e análise documental foi possibilitada a compreensão e identificação de convergências das temáticas de desenvolvimento sustentável e políticas de desenvolvimento territorial, bem como cruzamentos dos OSD e proposições do Plano Diretor analisado. Evidenciou-se que, dos 17 (dezessete) objetivos pactuados na Agenda 2030, 13 (treze) estão contemplados na redação Plano Diretor, embora, pela análise do Índice de Desenvolvimento Sustentável das Cidades - Brasil (IDSC-BR), apenas 2 (dois) foram integralmente atingidos. O estudo revelou que a grande maioria dos ODS estão presentes no planejamento da gestão municipal, mas não foram implementados efetivamente no âmbito do Município. Nessa perspectiva, far-se-á necessário aprofundar esse diálogo entre o Plano Diretor do Município e ações práticas para o efetivo cumprimento dos ODS com participação do governo, sociedade civil e iniciativa privada.
Experience of Using Bifactor Models to Reduce the Effects of Social Desirability on the Normative Questionnaire of Universal Competencies
Authors: Сагитов Егор , Брун Ирина , Павлов Станислав 
Published: November 2023

One of the significant lack of questionnaires is a scores distortion for the measured constructs, associated with the social desirability effects. An even greater threat to the validity of decisions is social desirability in high-stakes evaluation, such as selection for a position. Moreover the issue of the relationship between different components of social desirability and the most frequently measured personal constructs remains debatable. In the material of the author's normative questionnaire of universal competencies, an approach is considered for making adjustments to the final scores for measured constructs using the developed scales of egoistic and moralistic social desirability. Also discussed the prospect of using statement formulations that are neutral to social desirability or express the most positive degree of measured indicators.
The empirical basis of this study is data gathered within a pilot conducted in the spring of 2022, during which data were obtained from 579 respondents in 49 measurable competencies. The analysis was aimed at assessing the quality of the developed scales of social desirability and modeling of each of the universal competencies scales was carried out with the inclusion of a scale of social desirability. The data were analyzed in the framework of structural modeling - confirmatory factor analysis (CFA) using bifactor models for each of the measured competencies.
According to the results of this study, the use of the scale of egoistic social desirability as a measure for adjusting factor scores for the competencies has generally satisfactory psychometric statistics, but there is concern about the relatively large measurement error. The paper discusses the advantages and disadvantages of this approach and other practices that are most often used to reduce the effects of social desirability in the academic and business environment.

Published: November 2023

Qualitative measurement is a fundamental requirement for research practice in the social sciences. The quality of measurements determines the validity of the interpretations, conclusions and decisions we can make based on the data obtained from the measurements. Qualitative measurement in the social sciences requires assessment tools as well as data analysis methods to link observed measurement results to theoretical attributes. The scientific basis for their development is provided by psychometrics.
Preceding the special issue of the journal "Voprosy obrazovaniya / Educational Studies Moscow" devoted to psychometrics, the guest editors of this issue cover the main milestones of the history of psychometrics, highlight some significant publications, note the professional institutions and authors who have made their valuable contribution to the development of this branch of science. The authors pay special attention to the history of psychometrics in Russia. Assessing the possibilities, prospects and limitations of psychometrics, the authors express their point of view on the debatable issues of psychometrics, and it does not always coincide with the opinion of the authors of the special issue. This issue presents examples of using modern psychometric methods to solve actual problems in education research, as well as in research at the intersection of education and psychology, education and different spheres of business. All the authors of the presented articles are united by the desire to improve research practice in the social sciences through truly qualitative measurements.

Antihyperglycaemic Effect of Tetrahydrocurcumin and Pterostilbene: Effect on Key Metabolic Enzymes of Carbohydrate Metabolism in Streptozotocin Induced Diabetes
Authors: Pidaran Murugan  
Published: November 2023

This study is to assess the glucose lowering activity of tetrahydrocurcumin (THC) and pterostilbene (PTS), in diabetes induced rats by streptozotocin (STZ) and nicotinamide. Diabetic rats were treated THC (80 mg/kg body weight) and PTS (40 mg/kg body weight) for 45 days, after which activities of hexokinase, glucose-6-phosphate dehydrogenase, glucose-6-phosphatase, fructose-1,6-bisphosphatase, sorbitol dehydrogenase in liver and glycogen content in liver and muscle were assayed. The activities of gluconeogeneic enzymes were significantly increased, whereas the activities of hexokinase, glucose-6-phosphate dehydrogenase and glycogen were significantly decreased in diabetic control rats. Both THC and PTS were able to restore the altered enzyme activities to almost near normal levels. THC was more effective than PTS. Our results indicate that administration of THC and PTS to diabetic animals normalizes blood glucose and causes marked improvement of altered carbohydrate metabolic enzymes during diabetes. The THC administration showed more effective than PTS and metformin.
