Authors: Wang Yang , Wang Yifeng , Fan Peng
Published: June 2022

The purpose of this research is to develop a value chain management model for agricultural eco-innovation that can encompass different aspects to create value. It employs the Graphical Evaluation and Review Technique (GERT), which translates the remanufacturing operational process into a stochastic network. A GERT network covers two main points: its probability component and its parameter component. With the function of the GERT network, it can accomplish a certain state transition, which is presented to the extent of randomness in the process of occurrence. For this system, the number of resources in the GERT network may serve as a reference throughout its entire transition phase in order to show the complete transmission relationship between each node. The main contribution of this research is: Instead of analyzing the value flow mechanism of the eco-innovation value chain of agricultural products, we provide a theoretical basis for the application of multi-objective planning in the value flow of agricultural green innovation, which is conducive to the long-term development of the value chain of agricultural eco-innovation.

Authors: Liu Yang , Jing Huiting , Ye Tingqing
Published: June 2022

This paper proposes a new interest rate model by using uncertain mean-reverting differential equation. Based on the model, the pricing formulas of the zero-coupon bond, the interest rate ceiling and interest rate floor are derived respectively according to Yao-Chen formula. The symmetry appears in mathematical formulations of the interest rate ceiling and interest rate floor pricing formula. Furthermore, the model is applied to depict Hong Kong interbank offered rate (Hibor). Finally the parameter estimation by the method of moments and hypothesis test is completed.
Node-Based QoS-Aware Security Framework for Sinkhole Attacks in Mobile Ad-Hoc Networks
Authors: Esiefarienrhe Bukohwo Michael , Phakathi Thulani , Lugayizi Francis
Published: June 2022

Most networks strive to provide good security and an acceptable level of performance. Quality of service (QoS) plays an important role in the performance of a network. Mobile ad hoc networks (MANETs) are a decentralized and self-configuring type of wireless network. MANETs are generally challenging and the provision of security and QoS becomes a huge challenge. Many researchers in literature have proposed parallel mechanisms that investigate either security or QoS. This paper presents a security framework that is QoS-aware in MANETs using a network protocol called optimized link state routing protocol (OLSR). Security and QoS targets may not necessarily be similar but this framework seeks to bridge the gap for the provision of an optimal functioning MANET. The framework is evaluated for throughput, jitter, and delay against a sinkhole attack presented in the network. The contributions of this paper are (a) implementation of a sinkhole attack using OLSR, (b) the design and implementation of a lightweight-intrusion detection system using OLSR, and (c) a framework that removes fake routes and bandwidth optimization. The simulation results revealed that the QoS-aware framework increased the performance of the network by more than 70% efficiency in terms of network throughput. Delay and jitter levels were reduced by close to 85% as compared to when the network was under attack.

Snakebite is a neglected tropical disease that causes high rates of global mortality and morbidity. Although snakebite can cause a variety of pathologies in victims, haemotoxic effects are particularly common and are typically characterised by haemorrhage and/or venom-induced consumption coagulopathy. Despite polyclonal antibody-based antivenoms being the mainstay life-saving therapy for snakebite, they are associated with limited cross-snake species efficacy, as there is often extensive toxin variation between snake venoms, including those used as immunogens for antivenom production. This restricts the therapeutic utility of any antivenom to certain geographical regions. In this study, we explored the feasibility of using recombinantly expressed toxins as immunogens to stimulate focused, pathology-specific, antibodies in order to broadly counteract specific toxins associated with snakebite envenoming. Three snake venom serine proteases (SVSP) toxins, sourced from geographically diverse and medically important viper snake venoms, were successfully expressed in HEK293F mammalian cells and used for murine immunisation. Analyses of the resulting antibody responses revealed that ancrod and RVV-V stimulated the strongest immune responses, and that experimental antivenoms directed against these recombinant SVSP toxins, and a mixture of the three different immunogens, extensively recognised and exhibited immunological binding towards a variety of native snake venoms. While the experimental antivenoms showed some reduction in abnormal clotting parameters stimulated by the toxin immunogens and crude venom, specifically reducing the depletion of fibrinogen levels and prolongation of prothrombin times, fibrinogen degradation experiments revealed that they broadly protected against venom- and toxin-induced fibrinogenolytic functional activities. Overall, our findings further strengthen the case for the use of recombinant venom toxins as supplemental immunogens to stimulate focused and desirable antibody responses capable of neutralising venom-induced pathological effects, and therefore potentially circumventing some of the limitations associated with current snakebite therapies.

Published: June 2022

Fumonisins are a group of closely related mycotoxins produced by Fusarium, Alternaria alternata and Aspergillus species. Their occurrence is correlated with various factors during growth, processing and storage. Fumonisins occurrence data in the literature mainly include the B group of fumonisins (FB1 & FB2) in raw materials, showing high frequency of positive samples in a wide range of concentrations. In this study, a total of 933 grains (63.7%) and poultry feed (36.3%) samples, collected in the 16-year period (2006–2021), were analysed with commercial enzyme-linked-immunosorbent assay for detection of three fumonisins (FB1, FB2 & FB3). All positive and suspect samples were confirmed with high-performance-liquid-chromatography method with fluorescence detection. Overall, we have determined high occurrence of FBs in grains and poultry feed in all tested years, while the lowest occurrence was determined in 2019, followed by 2009 and 2008. Although, contamination levels varied from year-to-year, majority of analyzed samples in all tested years were around 1 mg/kg, while the maximum values varied from 3 mg/kg to 22.23 mg/kg. This study highlights the importance of regular monitoring of raw materials and understanding of the fate of FBs in the food chain in order to avoid undesirable health effects in animals and accompanied economic losses.
Investigating the Human Host—ssRNA Virus Interaction Landscape Using the SMEAGOL Toolbox
Authors: Lal Avantika , Galvao Ferrarini Mariana , Gruber Andreas J.
Published: June 2022

Viruses have evolved numerous mechanisms to exploit the molecular machinery of their host cells, including the broad spectrum of host RNA-binding proteins (RBPs). However, the RBP interactomes of most viruses are largely unknown. To shed light on the interaction landscape of RNA viruses with human host cell RBPs, we have analysed 197 single-stranded RNA (ssRNA) viral genome sequences and found that the majority of ssRNA virus genomes are significantly enriched or depleted in motifs for specific human RBPs, suggesting selection pressure on these interactions. To facilitate tailored investigations and the analysis of genomes sequenced in future, we have released our methodology as a fast and user-friendly computational toolbox named SMEAGOL. Our resources will contribute to future studies of specific ssRNA virus—host cell interactions and support the identification of antiviral drug targets.

Authors: Sultan Rabab Hussain , Abdallah Maged , Ali Tarek M. , Ahmed Amr E. , Assal Hebatallah Hany , Elesawy Basem H. , Ahmed Osama M.
Published: June 2022

Background: Higher expression of angiotensin-converting enzyme-2 (ACE-2) in addition to neuropilin-1 (NRP-1) can lead to a cytokine storm which is correlated to higher mortality rate and contributes to the progression of renal diseases and the pathogenesis of coronary heart disease (CHD) in COVID-19 patients. Aim: We herein sought to examine correlations between cytokine levels, ACE-2 and NRP-1 expression, renal function biomarkers, and cardiac enzymes in COVID-19 patients. Patients and Methods: For the study, 50 healthy subjects and 100 COVID-19 patients were enrolled. Then, confirmed cases of COVID-19 were divided into two groups—those with moderate infection and those with severe infection—and compared to healthy controls. Serum creatinine, urea, CK-MB, LDH, troponin I, IL-1β, IL-4, IL-10, IL-17, and INF-γ levels were estimated. We also studied the gene expression for ACE-2 and NRP-1 in blood samples utilizing quantitative real-time polymerase chain reaction (qRT-PCR). Results: All COVID-19 patients demonstrated a significant increase in the levels of serum creatinine, urea, CK-MB, LDH, and troponin I, as well as examined cytokines compared to the healthy controls. Furthermore, ACE-2 mRNA and NRP-1 mRNA expression levels demonstrated a significant increase in both severe and moderate COVID-19 patient groups. In the severe group, serum creatinine and urea levels were positively correlated with IL-10, INF-γ, NRP-1, and ACE-2 expression levels. Moreover, LDH was positively correlated with all the examined cytokine, NRP-1, and ACE-2 expression levels. Conclusion: Deficits in renal and cardiac functions might be attributable to cytokine storm resulting from the higher expression of ACE-2 and NRP-1 in cases of COVID-19.

Unlocking the Potential of Permeable Pavements in Practice: A Large-Scale Field Study of Performance Factors of Permeable Pavements in The Netherlands
Authors: Veldkamp Ted Isis Elize , Boogaard Floris Cornelis , Kluck Jeroen
Published: June 2022

Infiltrating pavements are potentially effective climate adaptation measures to counteract arising challenges related to flooding and drought in urban areas. However, they are susceptible to clogging causing premature degradation. As part of the Dutch Delta Plan, Dutch municipalities were encouraged to put infiltrating pavements into practice. Disappointing experiences made a significant number of municipalities decide, however, to stop further implementation. A need existed to better understand how infiltrating pavements function in practice. Through 81 full-scale infiltration tests, we investigated the performance of infiltrating pavements in practice. Most pavements function well above Dutch and international standards. However, variation was found to be high. Infiltration rates decrease over time. Age alone, however, is not a sufficient explanatory factor. Other factors, such as environmental or system characteristics, are of influence here. Maintenance can play a major role in preserving/improving the performance of infiltrating pavements in practice. While our results provide the first indication of the functioning of infiltrating pavement in practice, only with multi-year measurements following a strict monitoring protocol can the longer-term effects of environmental factors and maintenance actually be determined, providing the basis for the development of an optimal maintenance schedule and associated cost–benefit assessments to the added value of this type of climate adaptation.

Authors: Samansiri Srimal , Fernando Terrence , Ingirige Bingunath
Published: June 2022

Deaths and property damage from floods have increased drastically in the past two decades due to various reasons such as increased populations, unplanned developments, and climate change. Such losses from floods can be reduced by issuing timely early warnings and through effective response mechanisms based on situational intelligence during emerging flood situations. This paper presents the outcome of a literature review that was conducted to identify the types and sources of the intelligence required for flood warning and response processes as well as the technology solutions that can be used for offering such intelligence. Twenty-seven different types of intelligence are presented together with the technologies that can be used to extract such intelligence. Furthermore, a conceptual architecture that illustrates how relevant technology solutions can be used to extract intelligence at various stages of a flood cycle for decision-making in issuing early warnings and planning responses is presented.
From Traditional to Electrified Urban Road Networks: The Integration of Fuzzy Analytic Hierarchy Process and GIS as a Tool to Define a Feasibility Index—An Italian Case Study
Authors: Nodari Claudia , Crispino Maurizio , Toraldo Emanuele
Published: June 2022

To achieve sustainable development in the road sector, the use of Electric Vehicles (EVs) appears as a positive response to transport emissions. Among the available technologies, dynamic charging seems to overcome the main weakness points of EVs, even if it requires that traditional roads (t-roads) be equipped with a system providing electricity for EVs. Thus, so-called electrified roads (e-roads) must be implemented into the urban road networks. Since it is not possible to electrify all roads simultaneously, and also to consider the demand needs of citizens, a selection criterion is essential. This research describes and develops a simple, self-explanatory, repeatable, and adaptable selection criterion aimed at helping city managers in prioritizing the roads of an urban network to be upgraded from t-road to e-road status. This method belongs to the so-called Multicriteria Spatial Decision Support Systems (MC-SDSS)—processes useful for solving spatial problems through the integration of multicriteria analysis (Fuzzy Analytic Hierarchy Process, F-AHP) with a geo-referenced data management and analysis tool (GIS). The developed algorithm is based on several criteria related to the infrastructure/transport, social and environmental areas. The result of the implemented method is a Feasibility Index (FI), able to prioritize the roads most eligible to be upgraded as e-roads, as also verified by its application on the urban area of Milan (Italy).

Authors: Delyagin V.M. , Doctorova N.M. , Belokrinitskaya I.Ye.
Published: June 2022

Ebstein’s anomaly is a rare congenital malformation characterized by apical displacement of the right atrioventricular ring with an anomaly of the development of the tricuspid valve and the frequent presence of other heart defects. According to our data, this defect was diagnosed in 2 cases in more than 6 000 sectional studies: in an adult and a child. According to the echocardiography rooms of non-specialized multidisciplinary children's hospitals and children's polyclinics, the defect is detected with a frequency of 1:24.000–1:32.000 studies. Genetic and environmental factors (viral infections, benzodiazepines, lithium) are indicated as probable causes. Clinical signs are cyanosis, shortness of breath, heart failure, cardiac arrhythmias. Morphologically there are abnormalities of the tricuspid valve, papillary muscles and chordal apparatus, right ventricular myocardial hypertrophy, thinning of the walls of the right atrium and atrialized part of the right ventricle. Decisive for the diagnosis is ultrasound. Displacement of the right atrioventricular ring is revealed. The degree of bias determines the severity of the defect. The amplitude of the tricuspid valve movement is increased. Its valve closure occurs later than the mitral. A 40 ms difference between the tricuspid and mitral valve closure points is a diagnostically important sign of Ebstein’s anomaly. The tactics of a doctor are determined by the clinical picture

Published: June 2022

The development of smart wearable electronic devices puts forward higher requirements for future flexible electronics. The design of highly sensitive and high-performance flexible pressure sensors plays an important role in promoting the development of flexible electronic devices. Recently, MXenes with excellent properties have shown great potential in the field of flexible electronics. However, the easy-stacking inclination of nanomaterials limits the development of their excellent properties and the performance improvement of related pressure sensors. Traditional methods for constructing 3D porous structures have the disadvantages of complexity, long period, and difficulty of scalability. Here, the gas foaming strategy is adopted to rapidly construct 3D porous MXene aerogels. Combining the excellent surface properties of MXenes with the porous structure of aerogel, the prepared MXene aerogels are successfully used in high-performance multifunctional flexible pressure sensors with high sensitivity (306 kPa
-1
), wide detection range (2.3 Pa to 87.3 kPa), fast response time (35 ms), and ultrastability (>20,000 cycles), as well as self-healing, waterproof, cold-resistant, and heat-resistant capabilities. MXene aerogel pressure sensors show great potential in harsh environment detection, behavior monitoring, equipment recovery, pressure array identification, remote monitoring, and human-computer interaction applications.

Authors: COŞKUN TOPUZ Fatma , AKFIRAT Seda
Published: June 2022

Consumption of hard-shelled fruits is increasing because of containing high amounts of mineral substances, vitamins, antioxidants, and polyphenols. Aflatoxins are toxic substances usually produced by fungi called Aspergillus flavus or Aspergillus parasiticus and have carcinogenic effect. Aflatoxin contamination in hard-shelled fruits, which have an important place in the domestic and foreign markets, is one of the leading negative situations that threaten human health and cause serious economic losses to producers in international markets. For this reason, aflatoxin contamination limit has been set for each hard-shelled fruit traded by food organizations. Fresh fruits, vegetables, and hard-shelled fruits have a substantial share in our country's agricultural exports. Among the hard-shelled fruits, pistachio is a product with high economic value and highly demanded both at national and international. Producer companies are worried about some obstacles and economic losses in the international trade of pistachios. In this study, the factors that cause aflatoxin in pistachios and solutions are discussed. In addition, it is the basis of the study to control possible food safety hazards that are harmful to human health and to contribute to the prevention of economic losses experienced by producers in national or international trade.
Historia y Relaciones Internacionales. Carlos Escudé: una lectura desde la Periferia
Authors: Álvarez Silvia
Published: June 2022

A partir de la segunda mitad del siglo XX, América Latina participa, desde el campo teórico, en la revisión de los modos de interpretar el sistema internacional, fuertemente influida por su condición de periférica en un sistema internacional signado históricamente por las políticas de poder de los “grandes” actores internacionales y las fuerzas diversas que los atraviesan. Se plantea, de este modo, la necesidad de superar las lógicas del poder y los modos de interpretar la política internacional desde sus propias rutas teóricas. Es así como el logocentrismo de las Relaciones Internacionales, en clave presentista y estatocéntrica, es revisitado, desde la Periferia, para construir, en diálogo con la historia, nuevos enfoques teóricos. En ese contexto, surge en la década del ‘90 desde la Argentina, el Realismo Periférico, una teoría de Relaciones Internacionales elaborada por Carlos Escudé. La pregunta a plantearse es cuál es la importancia que asigna a la historia en la explicación de las Relaciones Internacionales, teniendo en cuenta que, desde su lectura realista, se presentan en tensión la inmutabilidad del sistema internacional en términos de relaciones de poder, el imperativo de que la Periferia acepte sus reglas en pos de su insercióninternacional y las trayectorias de la humanidad bajo los supuestos del poder.

EFFECTS OF REPLACEMENT OF FARM- MADE FEED WITH LANSY PL ON GROWTH AND SURVIVAL RATE OF THE GIANT FRESHWATER PRAWN (Macrobrachium rosenbergii) LARVAE
Authors: Pham Day Van
Published: June 2022

This study aimed to research the effects of replacing farm-made feed with Lansy PL. The experiment consisted of 4 treatments in which giant freshwater prawn larvae were fed with different feeding regimes. Treatment 1(Control) consisted of 03 feeding times of farmmade feed and 02 times of Artermia per day; Treatment 2 consisted of 2 times of farm-made feed, 1 time of Lansy PL and 2 times of Artermia per day; Treatment 3 consisted of 1 time of farmmade feed, 2 times of Lansy PL and 2 times of Artermia per day; and Treatment 4 consisted of 3 times of Lansy PL and 2 times of Artermia per day. Each container for larval rearing was made of plastic and had a volume of 120 liters, and larvae were stocked at a density of 60 inds/l with water salinity at 12o=oo. After 30 days of rearing, Treatment 3 reached the highest metamorphosis index of 10.73 ± 0.06, whichwas not statisticaly different (p > 0.05) than the treatment substituting Lanzy PL 1 time per day, but was statistically different from the other two treatments. The length of Postlarvae 15 was 9.83 ± 0.09 mm, and the survival rate was 62.78 ± 0.66%. Its yield of 37.67 ± 0.40 fish/L was also the best and was statistically different compared to the rest of the treatments. Therefore, the results of the study conclude that replacing farm-madefeed with Lansy PL for 2 meals per day gives the  best results when rearing giant freshwater prawn larvae.
Intelectuales, universidad y política en los años sesenta
Authors:   , Ghilini Anabela
Published: June 2022

La presente tesis doctoral propone un análisis sociohistórico de una peculiar experiencia universitaria: las Cátedras Nacionales de la Carrera de Sociología de la Facultad de Filosofía y Letras de la Universidad de Buenos Aires. Esta experiencia está relacionada con el proceso de politización y acercamiento al peronismo de una parte de los sectores medios y universitarios durante el período que se inicia hacia fines de los años sesenta. Estas cátedras son frecuentemente recordadas porque estimularon la reorientación de intelectuales y militantes universitarios hacia dicho movimiento. Además, renovaron el ámbito de las Ciencias Sociales al articular el conocimiento acerca de la realidad social nacional y latinoamericana con la lucha por la liberación y la revolución. El objetivo de esta investigación consiste en reconstruir el proyecto político e intelectual de las Cátedras Nacionales a partir de dos ejes analíticos: el primero exige reconstruir el proyecto en las diversas dimensiones en que las que se desplegó, para dar cuenta del contenido y alcances de una empresa que decidió enfrentar a tradiciones teórico-disciplinares ya instaladas y construir una “sociología nacional”. El segundo buscará dar cuenta de las Cátedras Nacionales como experiencia política, para lo cual indagará en su contribución en la emergencia de agrupaciones que se definieron como peronistas y que forjaron un nuevo proyecto para la universidad. Para realizar esta tesis optamos por una estrategia metodológica de tipo cualitativa, basada en el relevamiento y análisis de diversas fuentes documentales escritas junto con testimonios y entrevistas a quienes fueron los protagonistas de estos acontecimientos.

Published: June 2022

As the cryptocurrency market dynamically evolves, important financial and economic issues arise. The main focus of the present research is on the price of cryptocurrencies. Following the exploration of the literature base, special emphasis was put on the comparison between the crypto market and markets for different asset classes (gold, stocks, foreign currency) and on the identification of connection points. Next, the article focuses on the period after 2020, and applies the event study methodology in order to establish, how the two cryptocurrencies with the highest market capitalization (Bitcoin and Ethereum) reacted to selected events. These events mainly encompassed hacker attacks aimed at the systems that form the basis of the operation of cryptocurrencies, and also certain steps regarding their regulation and application.

The Relationship Between Asset Purchases, Monetary Aggregates, and Inflation Between 2007 and 2022 – an Example of the Federal Reserve
Authors: Csiki Máté
Published: June 2022

The large asset purchase programs following the 2008 crisis led to a significant expansion of money aggregates, which led to an appreciation of the relationship between inflation and money supply. In this study, I analysed the changes in monetary aggregates caused by quantitative easing, the framework for the implementation of monetary policy with ample reserves and their impact on price levels using a vector autoregressive (VAR) model between 2007 and 2022 based on data for the United States. The study includes the pandemic after 2020, however, due to the limited length of time available and the uncertainty of the effects, the focus of the study is on pre-pandemic processes. Inflation fears caused by the significant expansion of the money supply during the period were not substantiated due to the increase of excess reserves, the changing monetary policy operational framework and negative output gap. According to the model monetary aggregate shocks are built into inflation expectations, changes in the money aggregates caused by asset purchases help the central bank to reach its medium-term inflation target.

A környezeti (E), szociális (S) és kormányzati (G) kritériumoknak való megfelelésről a vállalatoknak az ún. nem pénzügyi információkra vonatkozó közzétételek szabályrendszere (keretrendszer) szerint kell beszámolniuk. Tanulmányunkban azt vizsgáljuk, hogy milyen jellemzői vannak az ESG-jelentéseknek, azok tükrözik-e az egyes piaci szereplők fenntarthatósági tevékenységét, és melyek a kérdéskör legkurrensebb problémái. Kutatásaink során arra a megállapításra jutottunk, hogy számos egymással párhuzamosan létező – eltérő adatok közzétételét előíró – kötelező és önkéntes közzétételi előírás van, amelyek ezért csak részlegesen alkalmasak a vállalkozások fenntarthatósági tevékenységének az összehasonlítására. A vállalati jelentések egy része emellett csak alapelvi szinten foglalkozik az ESG-kérdésekkel, és csak kisebb hányaduk számol be konkrét intézkedésekről és elért eredményekről. Éppen ezért megfogalmaztuk azokat a javaslatokat is, amelyek a vállalatok ESG-mutatók alapján történő összemérhetőségét támogatják.
Kína mint a feltörekvő piacok és fejlődő országok szuverénhitelezője

A tanulmány három fő kérdése: 1. Milyen tendenciák figyelhetők meg a kínai szuverénhitelezésben? 2. Milyen, a nyugatitól eltérő szerződéses feltételrendszerrel zajlik? 3. Milyen javaslatok születtek az ebből fakadó kockázatok mérséklésére, és ezekből mi tűnik megvalósíthatónak? A kutatás a közelmúltban létrehozott adatbázisokra és szabályozói anyagokra támaszkodott. Kína jelenleg a világ legnagyobb szuverénhitelezője. Terjeszkedését már 2008 körül megkezdte, jóval a hivatalos szándék bejelentése előtt. A nyugati mintáktól eltérően számos olyan feltétel található a szerződéseiben, amelyek egy nemzetközi adósságrendezés szempontjából releváns kockázatot jelentenek. Céljuk kettős: erős biztosítékokkal történő profitszerzés, szükség esetén pedig „soft power” befolyásolás. Az „adósságcsapda diplomáciájával” viszont nem él Kína. A szuverénadósság-kezelés esetleges globális reformjához Kína bevonására minden bizonnyal szükség van, de hosszabb távon a kínai hitelezési feltételeknek is enyhülniük kellene.
Intelligibility and Recognition of Announcer's Speech during Electric Acoustic Conversions in a Transformer

Published: June 2022

The purpose of the article is to outline the procedure and the results of the study of the influence of the distance from the sound source to the transformer on speech intelligibility and speaker recognition by voice during electro-acoustic conversion in a transformer. Of all the existing methods for measuring speech intelligibility and voice recognition, the objectified method of articulatory syllabary tables was used. The choice of the method is due to the fact that with a large number of dictated and, accordingly, adopted syllables, the influence of various factors is averaged out. Averaging also occurs if different groups of speakers and auditors take part in the tests. This is the objectivity of the articulatory method. Objective results can also be obtained by using speech to precisely reproduce sound combinations that do not have a semantic load, since when receiving words or phrases, it is possible to think out and restore the elements of the speech distorted by the communication path. The experimental procedure was determined. For the study, a transformer was used as an electroacoustic transducer, and a multifunctional search device ST031M “Piranha” was used as a control and measuring equipment. The selection of speakers and auditors was carried out for the research team. The selection was carried out among men and women between the ages of 18 and 30 who had no obvious speech and hearing impairments and were native speakers of the Russian language. The dependences of the values of the level of speech intelligibility and recognition of the speaker's voice on the distance between the sound source and the transformer are derived. The distances from the sound source to the transformer are determined, at which speech intelligibility corresponds to different quality classes according to GOST 16600-72.
CONCEPTUALIZING AND OPERATIONALIZING ISLAMIC FINANCIAL LITERACY: A MULTIDIMENSIONAL FRAMEWORK
Authors: Md Nawi Farah Amalina , Ab Aziz Muhammad Ridhwan , Shahwan Syahidawati
Published: June 2022

Islamic financial literacy is a prerequisite for Muslim financial well-being. Despite the fact that Islam provides clear guidance on financial arrangements, Muslims, particularly in Malaysia, have demonstrated financial ineptitude as evidenced by poor financial behaviours and a high number of bankruptcies, which warrants due scrutiny by current research. Nevertheless, determining the actual level of Islamic financial literacy, let alone devising control measures, has been challenging due to the lack of a validated measurement model of Islamic financial literacy. Furthermore, the lack of a standard definition has hampered empirical research in this area. Therefore, this study aims to scrutinize the concept of financial literacy from Islamic standpoint prior proposing a standard measurement. Underpinned by the Theory of Family Resource Management (FRM), Islamic financial literacy is denoted by Islamic financial knowledge, Islamic financial attitudes, and Islamic financial behaviours. These three primary components are further broken down into three sub-components: Islamic financial products, Islamic philanthropy, and financial management. The proposed measurement of Islamic financial literacy would serve as a parameter for measuring the level of Islamic financial literacy of the community in various groups, allowing subsequent measures to strengthen it to be devised.
FRAUDULENT FINANCIAL REPORTING IN MALAYSIA: FROM FRAUD TRIANGLE THEORY PERSPECTIVE

Published: June 2022

Fraudulent financial reporting (FFR) activities have a negative impact on market value, companies' reputation, accounting profession credibility, and loss of investors' confidence in financial statements. Despite the establishment of new regulations and governance, the FFR cases in Malaysia keep on growing. The involvement of top management in fraud cases is induced by fraud triangle components, namely pressure, opportunity, and rationalisation. However, the impact of fraud triangle elements on fraudulent financial reporting is inconclusive. Hence, the objectives of this study are twofold: to determine the trend of fraudulent financial reporting in Malaysia for five years from 2016 to 2020 and to examine whether the fraud triangle elements have a significant impact on fraudulent financial reporting. This study used the Binary Logistic Regression model to achieve its second objective. The independent variables used to determine fraudulent financial reporting comprise fraud triangle elements, namely pressure, opportunity, and rationalisation. The fraudulent financial reporting is proxied by M-score of the Beneish model. This study provides empirical evidence that even though pressure and opportunity have no significant relationship with fraud likelihood, rationalisation has a significant impact on fraudulent financial reporting. Besides contributing to the literature on corporate fraud issues, this study offers imperative insights to financial information users in determining the possibility or indication of fraudulent reporting. Future research may incorporate other proxies for fraud triangle elements to augment this study or include companies with specific fraud cases, such as PN17.
