Relationship between virtual reality balloon analogue risk task and risky decision-making
Authors: Ju Uijong , Wallraven Christian
Published: February 2023

The balloon analogue risk task (BART) is widely used to assess risk-taking tendencies on behavioral tests. However, biases or unstable results are sometimes reported, and there are concerns about whether the BART can predict risk behavior in the real world. To address this problem, the present study developed a virtual reality (VR) BART to enhance the reality of the task and narrow the gap between performance on the BART and risk behavior in the real world. We evaluated the usability of our VR BART through assessments of the relationships between BART scores and psychological metrics and additionally implemented an emergency decision-making VR driving task to investigate further whether the VR BART can predict risk-related decision-making in emergency situations. Notably, we found that the BART score significantly correlated with both sensation-seeking and risky driving behavior. Additionally, when we split participants into groups with high and low BART scores and compared their psychological metrics, we found that the high-score BART group included more male participants and exhibited higher sensation-seeking and more risky decision-making in an emergency situation. Overall, our study shows the potential of our new VR BART paradigm to predict risky decision-making in the real world.

Background

Food contamination by Staphylococcus spp. enterotoxigenic strains is quite common and despite underreporting caused by the short duration of clinical symptoms and lack of medical care, staphylococcal food poisoning is one of the most common Foodborne Diseases (FBD) in the world. This study describes a systematic review protocol with meta-analysis on the prevalence and types of staphylococcal enterotoxins in food, and the profile of contaminated foods.

Methods

The research will be conducted through the selection of studies reporting the analysis of staphylococcal enterotoxins in food contaminated by Staphylococcus spp. Searches will happen on the following databases: Medline (OVID), GALE, Science Direct, CAB Direct (CABI), Google Scholar, in addition to manual search in the list of references of articles, directory of theses and dissertations, and countries’ health agencies. Reports will be imported into the application Rayyan. Two researchers will independently select studies and extract data, and a third reviewer will solve conflicting decisions. The primary outcome will be the identification of staphylococcal enterotoxins in food, and the secondary outcomes will include staphylococcal enterotoxin types and foods involved. To assess the risk of bias in the studies, the tool developed by the Joanna Briggs Institute (JBI) will be used. For data synthesis, a meta-analysis will be performed. However, in case that is not possible, a narrative synthesis of the most relevant results will be carried out.

Discussion

This protocol will serve as the basis for a systematic review that aims to relate the results of existing studies on the staphylococcal enterotoxin prevalence and types in food, and the profile of the contaminated foods. The results will broaden the perception of food safety risks, highlight existing literature gaps, contribute to the study of the epidemiological profile and may guide the allocation of health resources for the development of preventive measures related.

Financial playthings: Interrogating gamification in retail trading interfaces
Authors: Ferrari Braun Agustin , Gekker Alex
Published: February 2023

This paper critically interrogates the claims of game-like elements in online brokerages through an interface analysis of three platforms, eToro, Plus500 and DeGiro. The 2021 GameStop Short Squeeze, where coordinated Redditors influenced financial markets through the mass purchase by individuals of ‘meme stock’, was made possible through the availability of retail trading platforms. One popular reading of the events saw it as ‘gamification’ of trading, without necessarily defining how the term is applicable. While we do not find evidence of direct gamification, we offer an explanation of why the gamification discourse persists. The platforms subtly deploying affective grammars linked to playfulness, thus creating a feeling of play without explicit game-like elements. In so doing, they are not just encouraging users to trade extensively, but are calling into question the epistemic distinction between investment and play, which has underpinned the development of finance since the eighteenth century.

Published: February 2023

En este artículo se diferencian los aspectos de la variación que son relevantes para la investigación gramatical de aquellos otros que son pertinentes en el ámbito de la educación, o bien afectan a ambos dominios. En la primera parte se explica por qué ciertos conocimientos básicos sobre la variación en español deberían formar parte de la cultura lingüística general que habría que fomentar entre los hispanohablantes. En la segunda parte se explica por qué es necesario conocer en alguna medida las estructuras gramaticales de los fenómenos sujetos a variación, y no solo su distribución geográfica y social. En la última parte se aborda brevemente la relación entre variación y norma, y se relaciona con las cuestiones expuestas en las dos secciones anteriores.
The university role in new teacher learning – why it matters: Teach First trainee perspectives
Authors: Tillin Jane
Published: February 2023

An emphasis on school-led initial teacher training (ITT) in England has marginalised the university role and led to instrumental models of new teacher learning. Rather than commit to continued university involvement in new teacher learning like the rest of the UK, England appears to be following in the footsteps of the USA, where new graduate schools of education (nGSEs) train teachers without university input. School leaders and academics have sought to articulate the value of the university role in initial teacher education (ITE), but there is little understanding of trainee teacher perspectives. This article presents findings from in-depth qualitative research with Teach First trainees at IOE, UCL’s Faculty of Education and Society (University College London, UK). Trainee perspectives on the university role in their learning are explored, before the implications for the future of ITE and ITT are considered. Findings indicate a need to reposition the university as an inspirational learning environment for teachers from the beginning of, and throughout, their careers, enabling sustained critical and creative thinking away from the school context, so that, as one trainee articulates, teachers do not ‘stagnate because there is no distraction from the day job’, but continue to develop and maintain their commitment to the profession.
Fiscal Decentralization and its Effect on Poverty Alleviation: Case Study of Indonesia
Authors: Anggraeni Rima Melati , Khusaini Mohamad , Prasetyia Ferry
Published: February 2023

This research provides empirical evidence of the effect of fiscal decentralization on poverty alleviation and used data from 505 districts/cities in Indonesia from 2010 to 2019. The poverty rate is used as an indicator to measure the social condition of the area with the parameter of the percentage of the total population below the poverty line, while the fiscal decentralization indicator uses approach to the size of the ratio of PAD to total regional income and expenditure. The estimated results used the fixed effect model shows that fiscal decentralization have significant role to reduce the level of poverty in districts/cities nationally. From this estimation result, the recommended policy formulation is pro-poor fiscal decentralization through strengthening regional financial capacity, both optimizing Original Local Government Revenue (PAD), allocating Transfer Funds to Regions that are specific grants, improving the quality of spending and regional financial management, as well as mechanisms monitoring - better evaluation. In addition, the effectiveness and efficiency of regional government policies in dealing with socio-economic issues such as unemployment and growth population must also be considered.

Performance assessment of full depth asphalt pavements manufactured with high recycled asphalt pavement content
Authors: Toth Csaba , Petho Laszlo , Rosta Szabolcs , Primusz Peter
Published: February 2023

Reclaimed asphalt pavement (RAP) is generated during road rehabilitation and resurfacing projects. This highly valuable recycled material should be used for manufacturing fresh hot mix asphalt (HMA) for new asphalt pavement layers to ensure the highest added value and minimise environmental impact. The use of RAP is already common practice worldwide; however, incorporating RAP into the manufacturing of HMA is still very minimal in Hungary. As part of a research work HMA containing 20-50% RAP was designed, manufactured and tested. This paper discusses the performance tests carried out on laboratory and plant mixed asphalt mixes; using this data the overall full depth asphalt (FDA) pavement performance was predicted through general mechanistic pavement design. The outcomes of this paper showed that high RAP content asphalt mixes can have superior performance; this disproves the common perception that high RAP mixes are substandard road construction materials. The analysis performed in this paper found that asphalt mixes with high RAP content present low risk for in-situ performance. However, in order to achieve this outcome, the application of correct mix design methodology, appropriate RAP management and suitable asphalt plant capability for mass production are paramount.
ANALISIS SENTIMEN PADA ULASAN APLIKASI INVESTASI ONLINE AJAIB PADA GOOGLE PLAY MENGGUNAKAN METODE SUPPORT VECTOR MACHINE DAN MAXIMUM ENTROPY

Published: February 2023

Investment is money or asset to earn profits in the future. Online investment applications are already available, one of which is Ajaib. A review of Ajaib’s application is needed to find out reviews given are positive or negative. Sentiment analysis in Ajaib is used to see the user's response to Ajaib’s performance which is divided into positive and negative classes. Sentiment analysis of the Ajaib’s reviews classification can be used with the Support Vector Machine and Maximum Entropy methods. Support Vector Machine on non-linear problems inserts the kernel into a high-dimensional space, to find a hyperplane that can maximize the distance between classes. The kernel used in SVM is the Radial Basis Function (RBF) kernel with gamma parameters of 0.002 and Cost (C) of 0.1; 1; 10. Maximum Entropy is a classification technique that uses the entropy value to classify data with the evaluation model used, namely 5-fold cross-validation. The algorithm which has the highest accuracy and kappa statistics is the best algorithm for classifying the sentiments of Ajaib users. The results using the Support Vector Machine algorithm show the overall accuracy is 85.75% and the kappa accuracy is 58.07%. The results using the Maximum Entropy algorithm show an overall accuracy of 83% and kappa accuracy of 50.5%. This shows that sentiment using the Support Vector Machine has a better performance than Maximum Entropy.

Effects of plant essential oils and their constituents on Helicobacter pylori : A Review
Authors: Tran Thanh Hung , Luong Thi My Ngan , Bui Van Le , Tran Trung Hieu
Published: February 2023

Essential oils (EOs) obtained from different medicinal and aromatic plant families by steam distillation have been used in the pharmaceutical, food, and fragrance industries. The plant EOs and their broad diversity of chemical components have attracted researchers worldwide due to their human health benefits and antibacterial properties, especially their treatment of Helicobacter pylori infection. Since H. pylori has been known to be responsible for various gastric and duodenal diseases such as atrophic gastritis, peptic ulcer, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma, several combination antibiotic therapies have been increasingly used to enhance the eradication rate of the bacterial infection. However, in the last decades, the efficacy of the therapies has decreased significantly due to widespread emergence of multidrug resistant strains of H. pylori. In addition, side-effects from commonly used antibiotics and recurrence of the bacterial infection have drawn public health concern globally.Therefore, this review focuses on in vitro effects of plant EOs and their bioactive constituents on the growth, cell morphology and integrity, biofilm formation, motility, adhesion, and urease activity of H. pylori. Their inhibitory effects on expression of genes necessary for growth and virulence factor productions of the bacterial pathogen are also discussed. Further in vivo and clinical evaluations are required so that plant EOs and their bioactive constituents can be possibly applicable in pharmacy or as adjuvants to the current therapies of H. pylori infection.
Amendment Of Company Law: Resolving Demission State Of directors and Board of Commissioners Issue
Authors: Suhardiman Daniel , Pramono Nindyo
Published: February 2023

Law No. 40 of 2007 concerning Limited Liability Companies ("Law No. 40/2007") has become the main regulation with regard to corporate law for 15 consecutive years. During the enactment of Law No. 40/2007, there are several unsolvable issues that requires an amendment to the company law. One of the issues relate to Directors and Board of Commissioners term of office. In practice, the term of office for the Board of Directors and Board of Commissioners varies according to the articles of association of each company. Obstacles that may occur in the practice of running a company are obstacles in reappointing or replacing Directors and Commissioners whose term of office has ended. This is due to the absence of preventive arrangements in terms of the reappointment or replacement of the Directors and the Board of Commissioners whose term of office has ended due to a deadlock in holding the General Meeting of Shareholders ("GMS"). The Directors and Board of Commissioners will be in a state of demission and will no longer be able to act for and on behalf of the Company. Law No. 40/2007 has yet regulated such matters and leave the issues unsolvable. This study aims to discuss and analyze the amendment of Law No. 40/2007 to overcome the demission state of Directors and Board of Commissioners.

Problem nieufności do rządów narodowych w krajach Unii Europejskiej w kontekście postrzeganej niekompetencji w doborze środków do walki z pandemią COVID-19
Authors: Budzyński Łukasz
Published: February 2023

W artykule została podjęta analiza nieufności do rządów w krajach Unii Europejskiej. Zasadniczym przedmiotem badania było społeczeństwo tych krajów, traktowane jako jedna całość. W artykule postawiono dwa cele. Pierwszym z nich była charakterystyka krótkookresowego trendu obejmującego lata 2017–2021 i dotyczącego deklaracji nieufności do rządów narodowych w społeczeństwach Unii Europejskiej. Drugim z nich była odpowiedź na pytanie o wpływ postrzeganej niekompetencji technicznej rządów na nieufność polityczną. W badaniu szczególnie podjęto się próby wskazania wpływu postrzeganej niekompetencji w doborze środków do walki z pandemią COVID-19 w 2021 roku przez rządy narodowe krajów Unii Europejskiej na nieufność do nich. Do realizacji przyjętych celów zostały wykorzystane dane Eurobarometru. Pozwoliły one wskazać, iż pandemia COVID-19 w pierwszym okresie przyczyniła się nieznacznie do wzrostu zaufania do rządów, natomiast w dalszej perspektywie spowodowała wzrost nieufności do rządów narodowych. Szczegółowa analiza przeprowadzona w klauzurze ceteris paribus pokazała, iż postrzegana niekompetencja techniczna rządów, szczególnie w zakresie walki z pandemią COVID-19, jest istotnym czynnikiem generującym nieufność polityczną. Analiza została przeprowadzona w kontekście ogólnoeuropejskim bez wskazywania specyfiki oddziaływań dla poszczególnych krajów.
Inicjatywa Trójmorza. Role – funkcje – kontrowersje z perspektywy teorii europeizacji
Authors: Nitszke Agnieszka
Published: February 2023

Po sześciu latach od zawiązania Inicjatywy Trójmorza można podjąć próbę określenia jej ról i funkcji, a także znaczenia, jakie ten proces ma dla integracji europejskiej, w szczególności dla Unii Europejskiej. Celem artykułu jest przedstawienie współpracy 3SI z perspektywy integralności polityki Unii Europejskiej oraz określenia, na jakie korzyści liczą państwa tworzące ten format w kontekście polityki unijnej. Zbadaniu zostanie poddana hipoteza mówiąca, że Inicjatywa Trójmorza nie stanowi wartości dodanej integracji europejskiej i jest forum realizacji interesów narodowych poszczególnych państw, a nie całej grupy. Aby rozstrzygnąć hipotezę postawiono następujące pytania badawcze: P1: Jakie były powody ustanowienia 3SI?; P2: które państwo lub państwa jest/są liderem grupy?; P3: Jakie państwa trzecie angażują się we wspieranie współpracy 3SI i jakie są ich motywacje?; P4: Jakie deklarowane i faktyczne role i funkcje w systemie UE wypełnia 3SI?

Analiza zostanie poprowadzona z perspektywy teorii europeizacji. W badaniu zastosowano metody jakościowe, w tym metodę instytucjonalno-prawną, systemową oraz komparatystyczną.

Feasibility assessment of injection molding online monitoring based on oil pressure/nozzle pressure/cavity pressure
Authors: Tsou Hao-Hsuan , Huang Chung-Ching , Wang Zhi-Hao , Zhao Ting-Wei
Published: February 2023

This study produced a box-like product through injection molding, and pressure sensors were installed at the nozzle in the injection molding machine and mold cavity. Injection molding experiments were conducted with various process parameters to understand the correlations between the pressure of the cavity, nozzle, and oil pump. A high correlation (R > 0.95) between oil pressure and nozzle pressure could be found in the study. The oil pressure in the injection molding machine could fully describe the pressure variation of the molten plastic at the nozzle. However, the correlation between nozzle pressure and cavity pressure was slightly reduced due to changes in injection speed, melting temperature, and packing time. Thus, a suitable molding window can improve the correlation between oil pressure, nozzle pressure, and cavity pressure. This study provides a correlation between the three pressures and a reference for the future selection of process variables, an essential pretreatment for online monitoring.
Two-dimensional EMD with shape-preserving spline interpolation
Authors: Brown Wesley G. , van der Walt Maria D.
Published: February 2023

Empirical mode decomposition (EMD) is a popular, user-friendly, data-driven algorithm to decompose a given (non-stationary) signal into its constituting components, utilizing spline interpolation. This algorithm was first proposed in 1998 in the one-dimensional setting, and it employed standard cubic spline interpolation. Since then, different two-dimensional extensions of EMD have been proposed. In this paper, we consider one of these two-dimensional extensions and adapt it to use a shape-preserving interpolation scheme based on quadratic B-splines, ensuring that monotonicity and concavity in the input data are preserved. Using multiple numerical experiments, we show that this new scheme outperforms the original EMD, both qualitatively and quantitatively.
Community-wide collaboration is a must to reinstall trust in bioinformatics solutions and biomedical interpretation
Authors: Takan Savaş , Allmer Jens
Published: February 2023

Science has become a highly competitive undertaking concerning, for example, resources, positions, students, and publications. At the same time, the number of journals presenting scientific findings skyrockets while the knowledge increase per manuscript seems to be diminishing. Science has also become ever more dependent on computational analyses. For example, virtually all biomedical applications involve computational data analysis. The science community develops many computational tools, and there are numerous alternatives for many computational tasks. The same is true for workflow management systems, leading to a tremendous duplication of efforts. Software quality is often of low concern, and typically, a small dataset is used as a proof of principle to support rapid publication. Installation and usage of such tools are complicated, so virtual machine images, containers, and package managers are employed more frequently. These simplify installation and ease of use but do not solve the software quality issue and duplication of effort. We believe that a community-wide collaboration is needed to (a) ensure software quality, (b) increase reuse of code, (c) force proper software review, (c) increase testing, and (d) make interoperability more seamless. Such a science software ecosystem will overcome current issues and increase trust in current data analyses.
Efficient mutual authentication using Kerberos for resource constraint smart meter in advanced metering infrastructure
Authors: Hasan Md Mehedi , Ariffin Noor Afiza Mohd , Sani Nor Fazlida Mohd
Published: February 2023

The continuous development of information communication technology facilitates the conventional grid in transforming into an automated modern system. Internet-of-Things solutions are used along with the evolving services of end-users to the electricity service provider for smart grid applications. In terms of various devices and machine integration, adequate authentication is the key to an accurate source and destination in advanced metering infrastructure (AMI). Various protocols are deployed to lead the identification between two parties, which require high computation time and communicational bit operations for system development. Therefore, Kerberos-based authentication protocols were designed in this study with the assistance of elliptic curve cryptography to manage the mutual authentication between two parties and reduce the time and bit operations. The protocols were evaluated in a widely adopted tool, AVISPA, which builds an understanding of the proposed protocol and ensures mutual authentication without unauthorized knowledge. In addition, upon comparing security and performance assessments to the current schemes, it was found that the protocol in this study required less time and bits to transmit information. Consequently, it effectively provides multiple security features making it suitable for resource constraint smart meters in AMI.
Vereinfachtes Verfahren zur Ermittlung von Messunsicherheiten zur Bestimmung der Messprozesseignung industrieller Prüfprozesse
Authors: Wiedenmann Ernst , Schlüter Thomas
Published: February 2023

Aufgrund der Erfahrung in vielen Begutachtungen und Seminaren zur Berechnung von Messunsicherheiten, fällt es z.T. selbst ISO/IEC 17025 akkreditierten Prüf- und Kalibrierlaboratorien schwer, angemessene Messunsicherheiten zu berechnen. Hier soll deshalb erstmalig ein neues, vereinfachtes Verfahren zur Berechnung von Messunsicherheiten für industrielle Prüfprozesse vorgestellt werden. Neu daran ist, dass es ausschließlich auf der Berücksichtigung der Messsystemspezifikation (Gerätespezifikationen) und der erweiterten Vergleichpräzision (Präzision mit erweiterten Vergleichbedingungen) basiert. Dadurch wird es in der industriellen Praxis wesentlich einfacher Messunsicherheiten für Prüfprozesseignungen zu ermitteln, da Gerätespezifikationen in vielen Fällen vorliegen und die Bestimmung der erweiterten Vergleichpräzision bereits zum Werkzeug vieler Anwender gehört. Das Verfahren ist nicht für Kalibrierverfahren und die damit verbundenen Rückführungen geeignet. Im Rahmen von Konformitätsaussagen der industriellen Prüfprozesse kann es verwendet werden.
Expanding the choke margin of a mixed flow compressor stage for a micro gas turbine engine
Authors: van Eck Hano , van der Spuy Sybrand J. , Gannon Anthony J.
Published: February 2023

In an attempt to reduce engine frontal area, while maintaining a high single stage pressure ratio, mixed flow compressor stages are frequently used in micro gas turbine (MGT) engines. The expansion of the choke margin of such a mixed flow compressor is presented. The use of a crossover diffuser configuration in a mixed flow compressor stage has displayed superior performance results compared to legacy diffuser configurations, especially when geometric restrictions are enforced. A disadvantage of a crossover diffuser configuration is that it typically displays an inferior operating range compared to legacy diffuser configurations. In an attempt to expand the choke margin of a MGT mixed flow compressor, the use of tandem and splitter vane crossover diffuser configurations was evaluated. It was found that a low solidity first vane row configuration provided a 3% increase in choke margin. A splitter vane crossover diffuser configuration provided a 5.9% increase in choke margin. A tandem vaned diffuser with a reduced first row vane number provided a 7.8% increase in choke margin.
Was Noadiah a »Trustworthy« Prophet?
Authors: Korpman Matthew
Published: February 2023

According to popular scholarly consensus, the role of the classical prophets ceased following the rebuilding of Jerusalem during the Second Temple period. This paper will attempt to propose an explanation of 1 Maccabees’ comments about the cessation of prophecy by undertaking a careful and broad examination of the dynamics involved in the Hebrew Bible’s final chronological confrontation between a prophet and religious leader of Israel: Noadiah and Nehemiah. Attention will be given to exploring the basis for Nehemiah’s deliberate dismissal of prophecy and how his choices set a precedent for future leaders of Judah, culminating in the positions taken by the Hasmoneans. In conclusion, it will be argued that Nehemiah’s choice to elevate his own ability for insight above and against those who claimed a profession that typically was seen as granting exclusive access to such things, led to a gradual ostracization of prophets and a diminishing belief in their »trustworthiness«.
Hypertextuality Theory and Interpretation in and of the Pentateuch
Authors: Mattison Kevin
Published: February 2023

This article examines reworkings in and of the Pentateuch using the terms and categories of hypertextuality, a theory proposed by the structuralist literary critic Gérard Genette. Genette’s theory offers sophisticated ways to categorize literary interactions among texts and to make more explicit our assumptions about how interpretive texts functioned. It can therefore contribute to solving pressing issues in the study of the Hebrew Bible and Ancient Judaism, including the ongoing need to continue integrating these two fields.

The mechanisms of many diseases, including central nervous system disorders, are regulated by circadian rhythms. The development of brain disorders such as depression, autism, and stroke is strongly associated with circadian cycles. Previous studies have shown that cerebral infarct volume is smaller at night (active phase) than during the day (inactive phase) in ischemic stroke rodent models. However, the underlying mechanisms remain unclear. Increasing evidence suggests that glutamate systems and autophagy play important roles in the pathogenesis of stroke. Here, we report that GluA1 expression was decreased and autophagic activity was increased in active-phase male mouse models of stroke compared with the inactive-phase models. In the active-phase model, induction of autophagy decreased the infarct volume, whereas inhibition of autophagy increased the infarct volume. Meanwhile, GluA1 expression was decreased following activation of autophagy and increased following inhibition of autophagy. We used Tat-GluA1 to uncouple p62, an autophagic adapter, from GluA1 and found that this blocked the degradation of GluA1, an effect similar to that of inhibition of autophagy in the active-phase model. We also demonstrated that knock-out of the circadian rhythm genePer1abolished the circadian rhythmicity of the volume of infarction and also abolished GluA1 expression and autophagic activity in wild-type (WT) mice. Our results suggest an underlying mechanism by which the circadian rhythm participates in the autophagy-dependent regulation of GluA1 expression, which influences the volume of infarction in stroke.

SIGNIFICANCE STATEMENTCircadian rhythms affect the pathophysiological mechanisms of disease. Previous studies suggested that circadian rhythms affect the infarct volume in stroke, but the underlying mechanisms remain largely unknown. Here, we demonstrate that the smaller infarct volume after middle cerebral artery occlusion/reperfusion (MCAO/R) during the active phase is related to lower GluA1 expression and activation of autophagy. The decrease in GluA1 expression during the active phase is mediated by the p62–GluA1 interaction, followed by direct autophagic degradation. In short, GluA1 is the substrate of autophagic degradation, which mainly occurs after MCAO/R during the active phase but not the inactive phase.

Recently, Indonesia has entered the new normal era, where every daily activity must comply with health protocols, including in the tourism sector. The pandemic period also had an impact on the decline in tourists at various tourist objects, including halal tourism. This article discusses how to implement the concept of halal tourism and strategies during this new normal period. By using descriptive analytical method, the writer explains the findings and discussion in this article. Which with the concept of halal tourism, Muslim visitors still feel comfortable when visiting tourist attractions. In addition, to restore the tourism sector, the government has planned a new normal era tourism strategy.
Granting Inheritance to Extramarital Children in the Perspective of Islamic Law

Published: February 2023

At present there are many cases of early marriage caused by a person getting pregnant before the legal marriage takes place. This incident encouraged the community to enter into legal marriages resulting in children born out of wedlock. While, in customary law if a woman gives birth to a child out of wedlock, the child will only have a civil relationship with the mother. The legal relationship that a child has only with his mother means that the child is not entitled to become the heir of his biological father's family. The purpose of this study was to determine the status of children outside of marriage according to Islamic law and marriage law in Indonesia. In addition, this study also aims to find out and analyze the position of the inheritance rights of children outside of marriage along with the distribution of inheritance rights to children outside of marriage when compared to their siblings who are children with legal marriages.
Progress and challenges in experimental models for pheochromocytoma and paraganglioma
Authors: Tischler Arthur S , Favier Judith
Published: February 2023

Experimental models for pheochromocytoma and paraganglioma are needed for basic pathobiology research and for preclinical testing of drugs to improve treatment of patients with these tumors, especially patients with metastatic disease. The paucity of models reflects the rarity of the tumors, their slow growth, and their genetic complexity. While there are no human cell line or xenograft models that faithfully recapitulate the genotype or phenotype of these tumors, the past decade has shown progress in development and utilization of animal models, including a mouse and a rat model for SDH-deficient pheochromocytoma associated with germline Sdhb mutations. There are also innovative approaches to preclinical testing of potential treatments in primary cultures of human tumors. Challenges with these primary cultures include how to account for heterogeneous cell populations that will vary depending on the initial tumor dissociation and how to distinguish drug effects on neoplastic vs normal cells. The feasible duration for maintaining cultures must also be balanced against time required to reliably assess drug efficacy. Considerations potentially important for all in vitro studies include species differences, phenotype drift, changes that occur in the transition from tissue to cell culture, and the O2 concentration in which cultures are maintained.
Environmentally friendly behaviour in dentistry

Published: February 2023

Background and aims. Sustainability is the sensitive and responsible way of using the natural resources, its goal being to prevent their depletion and preserving the ecological balance. An essential requirement to achieve this is to practice environmentally conscious behavior. The main objective of the present study was to carry out a survey among dentists about the importance of sustainability, feasibility of an environmentally friendly dental practice and the steps in favor of it.

Methods. An online survey with 6 question groups, including a total of 50 questions, was performed. The survey was available online for dentists on different platforms. In total 98 responses were recorded during September − November 2020.

Results. Out of the responding dentists, 74.49% liked the idea of an environmentally friendly dental practice and 98.97% would take some steps toward environmental awareness in their practice. A statistically significant (p<0.05) difference between those who prefer an environmentally conscious practice and those who had not yet thought about it was only in the questions related to environmentally conscious lifestyle in their household, the use of environmentally friendly cleaning products, the creation of a ’green wall’ and selective waste collection in their practice.

Conclusions. Most of the respondents were open to the idea of forming an environmentally conscious dental practice and they would act to achieve it. In order to reach this, it is necessary to provide dentists with feasible solutions for better practice. Some of the guidance issues, which would be easy to implement, are listed at the end of the present study. We intend to provide a guidance regarding sustainable dental practice.
An ecoepidemic model with healthy prey herding and infected prey drifting away

Published: February 2023

We introduce here a predator–prey model where the prey are affected by a disease. The prey are assumed to gather in herds, while the predators are loose and act on an individualistic basis. Therefore their hunting affects mainly the prey individuals occupying the outermost positions in the herd, which is modeled via a square root functional response. The conditions of boundedness and uniform persistence are established. Stability and bifurcation analysis of all feasible equilibrium are carried out. Conditions on the model parameters for the possible existence of limit cycles are derived, global stability analysis is also shown in proper choice of suitable Lyapunov function. Numerical simulation of the various bifurcations validate the theoretical results. It is found that the system ultimate behavior depends mainly on two crucial parameters, the force of infection and predator average handling time. A discussion of the biological significance of the investigation concludes the paper.
Distributed optimization for multi-agent systems with communication delays and external disturbances under a directed network

Published: February 2023

This article studies the distributed optimization problem for multi-agent systems with communication delays and external disturbances in a directed network. Firstly, a distributed optimization algorithm is proposed based on the internal model principle in which the internal model term can effectively compensate for external environmental disturbances. Secondly, the relationship between the optimal solution and the equilibrium point of the system is discussed through the properties of the Laplacian matrix and graph theory. Some sufficient conditions are derived by using the Lyapunov–Razumikhin theory, which ensures all agents asymptotically reach the optimal value of the distributed optimization problem. Moreover, an aperiodic sampled-data control protocol is proposed, which can be well transformed into the proposed time-varying delay protocol and analyzed by using the Lyapunov–Razumikhin theory. Finally, an example is given to verify the effectiveness of the results.
Bounded solutions and Hyers–Ulam stability of quasilinear dynamic equations on time scales
Authors: Reinfelds Andrejs , Šteinberga Dzintra
Published: February 2023

We consider the quasilinear dynamic equation in a Banach space on unbounded above and below time scales T with rd-continuous, regressive right-hand side.We define the corresponding Green-type map. Using the integral functional technique, we find a new simpler, but at the same time, more general sufficient condition for the existence of a bounded solution on the time scales expressed in terms of integrals of the Green-type map. We construct previously unknown linear scalar differential equation, which does not possess exponentially dichotomy, but for which the integral of the corresponding Green-type map is uniformly bounded. The existence of such example allows, on the one hand, to obtain the new sufficient condition for the existence of bounded solution and, on the other hand, to prove Hyers–Ulam stability for a much broader class of linear dynamic equations even in the classical case.
