Authors: Gaikwad Ujjwala Nitin , Bose Oshrika , Padhi Abhishek , Jindal Atul , Nagpure Keshao , Bhargava Anudita , Das Padma
Published: May 2022

Background

Healthcare workers (HCWs) stand the risk of acquiring infection directly, while attending to patients or indirectly while handling and testing patient specimens. Considering this, the present study was planned to assess Personal Protective Equipment (PPE) breaches and exposures among HCWs working in COVID-19 wards/ screening areas and to evaluate their COVID-19 positivity rates post-exposure concerning the level of exposure, type of PPE breach, and the cadre of HCWs exposed in COVID-19 wards.

Methods

This retrospective cross-sectional study involved the analysis of all instances of PPE breaches which occurred during a period of nine months from June 2020 to February 2021 at a tertiary care level hospital in Central India. The analysis included all exposures involving any cadre of HCWs that occurred while handling the patients or while doffing the contaminated PPE in COVID -19 wards.

Results

A total of 347 PPE breaches were analyzed from the available records of the Hospital Infection Control team repository. Amongst the 347 breaches, 268 (77.2%) were classified as low-risk exposures and 79 (22.8%) as high-risk exposures. Cadre wise distribution of high and low-risk exposures revealed that, PPE breaches occurred most commonly in the category of nursing officers (n = 174, 50.1%). Among all of the breaches, 15.2% of high-risk exposures and 2.6% of low-risk exposures resulted in COVID-19 positivity with a cumulative positivity of 5.4%. Collectively, non-mask related breaches accounted for the majority (63.2%) of the positive COVID-19 cases.

Conclusion

Appropriate use of PPE by HCWs is vital for their protection. However, breaches in the use of PPE may occur while managing COVID-19 patients due to physical and mental exhaustion among HCWs resulting from work overload. Early identification and appropriate management of HCWs with high-risk exposures can help prevent transmission to other hospital staff and patients, thus preserving resources and workforce.
Transnational dreamscapes: Cinema and visual motifs in the 1929 Barcelona International Exposition
Authors: Garin Manuel , Elduque Albert
Published: May 2022

This article explores the connections between moving images and world fairs by focusing on a specific case: the Barcelona 1929 International Exposition. The event, a key moment in the city’s history, showcased cinema as a technological marvel, a vehicle for transnational influence and a tool for propaganda. After an introduction to the political and economic context of the exposition, our analysis covers four main areas: first, we document the role played by Palacio de Proyecciones, a sumptuous palace where new audio-visual devices and techniques were displayed; second, we trace the remains of the mysterious lost film Barcelona Trailer, where Hollywood stars greeted Hispanic audiences and praised the exhibition; third, we offer a critical analysis of the newsreels recorded by the film company CINAES and their mise en scène; finally, we compare visual motifs and shots from the 1929 footage with contemporary images produced today in Barcelona, examining the links between visual culture, technology and gender.

Platón, Carnéades y la Academia. Un estudio de caso acerca del conocimiento científico en contexto
Authors: Fernández Palazzo Ana Julia
Published: May 2022

El objetivo de este trabajo es estudiar el caso de la postura epistemológica de Carnéades como paradigmático de una concepción y un modo de lo que podríamos llamar “hacer ciencia” en la Academia platónica. Para ello se intentará mostrar que, si bien no hay una teoría unificada acerca del conocimiento a lo largo de la historia de la escuela fundada por Platón, se puede partir de dos rasgos característicos de ella que nos permiten dar cuenta, paradójicamente, de cierta comunidad de pensamiento: la desconfianza por la cognición sensible y la dialéctica como método de investigación por excelencia.

Francis Bacon y C. P. Snow: la integración de las dos culturas
Authors: Arancibia Gutiérrez Marcelo
Published: May 2022

La tesis acerca de la existencia de “las dos culturas” entre quienes gozan de una ecuación formal, propuesta en la segunda mitad del siglo XX por C. P. Snow (1959; 1964), tiene su precedente filosófico en los siglos XVI y XVII en la obra de Francis Bacon. Los problemas abordados por ambos autores muestran la relevancia y vigencia de los Estudios sobre Ciencia, Tecnología y Sociedad (CTS) para el siglo XXI.
Verifying Provable Stability Domains for Discrete-Time Systems Using Ellipsoidal State Enclosures
Authors: Rauh Andreas , Bourgois Auguste , Jaulin Luc
Published: May 2022

Stability contractors, based on interval analysis, were introduced in recent work as a tool to verify stability domains for nonlinear dynamic systems. These contractors rely on the property that - in case of provable asymptotic stability - a certain domain in a multi-dimensional state space is mapped into its interior after a certain integration time for continuous-time processes or after a certain number of discretization steps in a discrete-time setting. However, a disadvantage of the use of axis-aligned interval boxes in such computations is the omnipresent wrapping effect. As shown in this contribution, the replacement of classical interval representations by ellipsoidal domain enclosures reduces this undesirable effect. It also helps to find suitable ratios for the edge lengths if interval-based domain representations are investigated. Moreover, ellipsoidal domains naturally represent the possible regions of attraction of asymptotically stable equilibrium points that can be analyzed with the help of quadratic Lyapunov functions, for which stability criteria can be cast into linear matrix inequality (LMI) constraints. For that reason, this paper further presents possible interfaces of ellipsoidal enclosure techniques with LMI approaches. This combination aims at the maximization of those domains that can be proven to be stable for a discrete-time range-only localization algorithm in robotics. There, an Extended Kalman Filter (EKF) is applied to a system for which the dynamics are characterized by a discrete-time integrator disturbance model with additive Gaussian noise. In this scenario, the measurement equations correspond to the distances between the object to be localized and beacons with known positions.

Authors: Christiyanto Marry , Utama Cahya Setya
Published: May 2022

The aim of this study was to examine effect of length of chicken litter fermentation on chemical content and in vitro digestibility. Completely randomized design was applied in this study with 4 treatments and 4 replications. The treatments were T0 = no fermentation; T1 = fermentation of chicken litter for 3 weeks; T2 = fermentation of chicken litter for 6 weeks; and T3 = fermentation of chicken litter for 9 weeks. Parameters observed were chemical content and digestibility value of fermented chicken litter. Different fermentation time affected the chemical content of fermented chicken litter, namely water, fat, BETN and TDN content, but did not affect ash content and fiber content. Different fermentation time affected dry matter, protein, fiber fraction digestibility (ADF, NDF, Hemicellulose), but did not affect organic matter digestibility, VFA concentration, NH3 concentration and total protein production of chicken litter. Based on dry matter, ADF, NDF hemicellulose digestibility and VFA concentration, it is concluded that recommended ripen time for chicken litter fermentation is 6 weeks.

Authors: Tapdasan Emerson Pilongo , Salces C B , Salces A J
Published: May 2022

Feed resource availability and quality are two of the major factors limiting dairy production in the Philippines. Utilization of microbial-based feed additives and agricultural by-products such as cassava pulp aided by fermentation technology can help provide the needed resource. This study aimed to determine the effect of activated yeast (Saccharomyces cerevisiae) solution (AYS) and yeast-fermented cassava pulp (YFCP) on milk production and feed cost-efficiency in dairy buffaloes. The study followed RCBD design using 63 dairy buffaloes at the Philippine Carabao Center in Ubay Stock Farm, Bohol. The average daily milk yield (ADMY) of buffaloes supplemented with 0.5L AYS and 1L AYS twice daily were greater than that of control buffaloes by 0.67L and 0.69L, respectively (P = 0.0039).On the other hand, the ADMY of buffaloes fed with YFCP and YFCP+AYS were greater than that of control buffaloes by 0.64 and 0.68L, respectively (P = 0.0320). Supplementation of AYS and feeding YFCP yielded the lowest cost per liter of milk produced at PhP 20.25 and PhP 16.24, respectively. It is recommended to supplement milking dairy buffaloes with AYS or feeding YFCP in areas with cassava pulp to increase feed resource, increase milk production and improve feed cost-efficiency thereby increasing significantly the farmerâ€™s income.

Published: May 2022

This study aimed to determine the effect of in-ovo injection of L-arginine on hatchability, chick quality, performances, and muscle histology of native chicken. In-ovo injection was carried out on the 10th day. A total of 375 fertile eggs with an average weight ranged Â 39-43 g were grouped into 5 treatments. The first treatment was without injection (negative control), the second treatment was injection of NaCl solution 0.9% (positive control), the third treatment was injection of L-arginine solution 0.5 g per 100 ml of NaCl 0.9% (0.5%, m/v) The fourth treatment was injection of 1.0 g L-arginine solution per 100 ml of NaCl 0.9% (1.0%, m/v), and the fifth treatment was injection of 1.5 g L-arginine solution per 100 ml of NaCl 0.9% (1.5%, m/v). The injection was carried out at the pointed area of the egg in a vertical position (pointed below, blunt above). The Injection was carried out with a depth of 10 mm from the eggshell using an automatic injector. The results showed that all treatments produced the same hatchability. In-ovo injection of L-arginine has a beneficial effect on chick quality and post-hatch performance, the concentration of L-arginine solution used did not cause embryo death. In-ovo injection of 0.5% L-arginine increased hatching weight, weekly body weight, muscle mass, and myofiber size.

The language of antagonism in political texts: what does it struggle for?
Authors: Torrecilla N. Marcelino
Published: May 2022

This study seeks to delve further into antagonistic language in political texts and understand the rationale underlying them. Focus of analysis was on explicit evaluative language and lexical cohesion of two texts: “Freedom: a Sinn Fein Education Publication” (Text A) and “Democratic Unionist Party Manifesto” (Text B). Analysis showed that both texts drew on words related to unity and disunity to make their cases and attack each other. Text A appeared to be informative. This made it impersonal with no interaction with the reader. Text B explicitly addressed the reader. This was evidenced by the choice of you as an inclusive interactive personal pronoun.

What are the different ways in which we can understand gendered diasporic identities?
Authors: Buitrago Leal Roxana
Published: May 2022

Gender studies has facilitated the exploration of Aids and Migration among other social problems, and has enabled a more sensible understanding of the discrimination practices that exist around them. This paper will discuss the aspects in which gender studies have contributed to assess issues regarding migration from the gendered diaspora perspective. This sociological construction of diaspora encompasses the many different reasons why migrants decide to leave their country, bounded by national, racial or ethnic background, which enroll in a strong political motivation. Although in this essay, the theoretical discussion will embrace male gendered diasporas as well, critics of the term have questioned how gendered diasporas have been traditionally understood of men. The first part of the discussion will be guided by the question: what is a gendered diaspora identity? The essay will emphasise the gendered category of analysis. I will argue how gendered identities are constructed under the circumstances of dominance and oppression that result from displacement. First, the deconstruction of the social category of gendered diaspora will be assessed, through an examination of Ella Shohat ́s agreement of identity. The essay will then examine the term diaspora and its ambivalences and criticisms. The second part of the discussion will consider three separate cases of how gendered diasporic identities are being understood, including: the cultural representations of Cuban Americans, the Sikh diaspora and Armenian women in Los Angeles.

The paper discusses the diagnostic method of electromyography, which allows assessing the state of functioning of the nerve that innervates the damaged muscle. The method is based on registration and analysis of bioelectrical potentials of muscles and peripheral nerves. Purpose of the study: develop an algorithm of operation and a structural diagram of an electromyography device with the possibility of converting the recording results to a PC, display and smartphone via USB and bluetooth for their analysis. Materials and methods. A method is proposed for measuring muscle function, which involves observing the movement of muscles from the surface of the skin over the muscle. The muscle sensor gives an output signal depending on its activity. Using a surface electrode, you can track the overall movement of the muscles. Using the program for interfacing the Myoware EMG muscle sensor with the Arduino, we obtain an analog signal. The sensor values can be observed on the serial plotter. The next task was to read the sensor data or analog voltage on the LCD1602 display. We have connected the I2C pins (SDA and SCL) of the LCD1602 to A4 and A5 of the Arduino. LCD1602 module displays 2 lines of 16 characters. After downloading the special code LCD1602 via I2C, the display began to display the value of the EMG analog signal, as well as the voltage. The Arduino can communicate with other devices via Bluetooth using the HC-05 (zs-040) module. This module allows the Arduino to connect and communicate with other devices such as a smartphone, computer or other. Results. Based on the results of the study, an idea was obtained of the bioelectric potential that occurs in the muscle. The applied method of fixation of bioelectrical signals in muscles is of practical importance for clinical neurology; its implementation will facilitate and increase the diagnostic accuracy of electrophysiological studies. Conclusion. In this study, a structural diagram of the device and the solution of a technical problem based on technical requirements have been developed, and an algorithm for the device has been developed. 4,963 rubles were spent on the implementation of practical study taking into account the costs of basic and auxiliary materials, as well as other direct costs.

Published: May 2022

It is shown that the strengthening of the role of strategic management of industrial enterprises and corporations that has taken place in recent years requires the creation of new developments in the field of both improving the strategies for managing manufacturing companies themselves and the formation of appropriate information and analytical support for the mentioned process. The aim of the work was the need to develop an up-to-date information and analytical support for the strategic management of enterprises in the context of global instability in the world and a tough confrontation between Russia and the West. In this regard, the implementation of effective management of industrial enterprises and corporations is becoming an increasingly difficult task, the solution of which depends on an increasing number of factors, not only direct, but also increasingly significant indirect impact. Materials and methods. The study of the origin, formation and development of ideas of strategic management of industrial enterprises and organizations showed that the implementation of operational and strategic management of enterprises cannot be carried out, as was done in the very recent past, based on the experience of managers and simple unambiguous schemes development of management decisions.

Published: May 2022

Currently, the value of the information and communication technology development index in Russia is increasing every year, but it still lags far behind the values of world leaders. The specifics of the domestic experience of digital transformation of all spheres of the economy indicates that the main changes are more often carried out in separate vectors, rather than in a complex. This is a definite problem for the development of the digital ecosystem of the industry – a complex system of interconnected objects competing on a single digital platform and designed to solve specific tasks set for industry needs. And it should be considered not only at the level of state support, but also at the level of combining the forces of the state with science and private business. To do this, it is necessary to create stimulating factors in order to attract investment, which is especially important in the housing and communal services sector. The purpose of this study is to analyze the factors that make up the architecture of the digital ecosystem of housing and communal services, as well as to assess their mutual influence on each other. Methods of analysis and synthesis, economic-statistical and comparative methods, as well as mathematical modeling were used in the work. The authors analyzed current foreign and domestic scientific publications on the research topic, electronic collections of analytical research centers, and official statistical reports of state bodies. The results are a description of a three-factor model of the digital ecosystem of housing and communal services, consisting of performance indicators of digital services, competence characteristics of human resources and a set of functional digital services for housing and communal services. Conclusion. Considering the digital ecosystem of housing and communal services in a complex of three interrelated factors, it is possible to improve the quality of managerial decision-making in matters of modernization of digital management of housing and communal services. Moreover, mathematically describing the dependencies of the factors of the digital ecosystem, it is possible to move to the level of determining specific thresholds, after reaching which, the housing and communal services ecosystem will acquire an optimal configuration of elements and a higher digital potential.

Published: May 2022

The research objective of the present article is to study new world trends in industrial deve¬lopment and the reaction speed of national governments, companies and workers to technological changes. As research methods, analysis and synthesis of current world trends were applied, as well as special methods were used: expert assessments of international organizations were analyzed, a comparative and economic-statistical analysis was carried out. As a result, the distinctive features of Industry 5.0 are highlighted – this is the coexistence of industry and new social and environmental trends and needs. Change is inevitable: green energy and sustainable products will initially be a monopoly factor and benefit insiders. It is emphasized that in order to achieve global competitiveness, companies need to transform established business models and invest in technology and network forms of business, taking into account social goals: in addition to creating new jobs and ensuring flexible employment, we are talking about personalization of goods and greening. The poli¬tical and economic goals of the fifth industrial revolution and the direction of technological innovations are considered. It is emphasized that technology, according to the new approach, should serve people and society, which means that the technology used in production adapts to the needs and diversity of industry workers. The leaders are artificial intelligence, quantum information and semiconductors. Technological transformation is based on the development of the following areas: individual technologies for human-machine interaction, biotechnology and smart materials, artificial intelligence, digital twins, data transmission, storage and analysis technologies, as well as energy efficiency, renewable energy sources, storage and autonomy. It is an ecosystem-based innovation policy with a flexible focus on results. It is noted that technological transformation will help solve a number of unique social problems. It puts a bold focus from individual technologies to a system approach that allows the industry to achieve social goals beyond job creation and growth, and puts the well-being of industry workers at the center of the production process. In conclusion, the techno-social nature of the fifth revolution is revealed, with technology as tools and social needs as the ultimate goal.
UTILIZATION OF MEDIATION IN MEDICAL DISPUTE SETTLEMENT DURING COVID 19 PANDEMIC
Authors: Kusumaningrum Anggraeni Endah
Published: May 2022

Health services provided by doctors to patients during the COVID-19 pandemic can lead to medical disputes, such as the case of a patient who feels he has been infected with the virus even though the results of the PCR swab are negative, as well as the refusal of patients who are about to give birth because they have not had a PCR swab. Mediation can be used as an alternative to medical dispute resolution outside the court by involving the mediator in order to achieve a final result that is acceptable to the parties. This study uses a normative juridical approach and secondary data sources as the main data through primary, secondary, and tertiary legal materials and will be analyzed qualitatively. The obligation to carry out mediation in medical disputes is considered a faster and relatively inexpensive dispute resolution process and fulfills a sense of justice as regulated in Article 29 of Law No. 36 of 2009 concerning Health in accordance with Article 130 HIR and Article 154 Rbg that cases that do not take the Mediation procedure are a violation. To the provisions of HIR and Rbg. Similarly, PERMA No. 1/2016 concerning Mediation Procedures in Court as a substitute for PERMA No. 1/2008.
Numerical Investigation of Convective Heat Transfer and Fluid Flow Past a Three Square Cylinders Controlled by a Partition in Channel
Authors: Admi Youssef , Moussaoui Mohammed Amine , Mezrhab Ahmed
Published: May 2022

This document presents a research article on the control of fluid flow around three heated square cylinders placed side by side in a 2D horizontal channel using a flat plate. The objective of this research is to examine the effect of the position, length and height of a flat plate on fluid flow and heat transfer. For this purpose, numerical simulations are performed by using the Boltzmann double relaxation time multiple network method (DMRT-LBM). The MRT-D2Q9 and MRT-D2Q5 models are used to treat the flow and temperature fields respectively. In contrast to several existing investigations in the literature in this domain which study the passive control of the flow using a horizontal or vertical plate around a single cylinder, this work presents a numerical study on the effect of the position, length and height of a flat plate (horizontal and vertical) on three heated square cylinders on the flow and temperature fields. First, the effect of the position and length of the horizontal flat plate is examined. This study shows that the implementation of a flat plate of length Lp = 4D at a position g=3 behind the central cylinder reduces the amplitude of the Von Karman Street and allows large and regular heat exchange.  Thus, in the second part, the effect of the position and height of the vertical flat plate is studied. The results obtained show that the implementation of a flat plate of height h=2D at a position g=3 behind the central cylinder improves the thermal exchange between the incoming fluid and the heated cylinders. This numerical work could lead to the prediction of the cooling of the electronic components: The cooling of the obstacles is all the better when the control plate is arranged at g = 3 and its height h = 2D in the case of the vertical plate or its length Lp equal to 4D in the case where the plate is implemented horizontally
Improving instructional video design: A systematic review
Authors: Fyfield Matthew , Henderson Michael , Phillips Michael
Published: May 2022

Instructional videos are increasingly part of the teaching practices of educators across all sectors. The most common theoretical lens used to design and evaluate instructional videos has been to apply principles emerging from the cognitive theory of multimedia learning. However, these principles have been largely developed from research using instructional media other than videos. In addition, there is no comprehensive list of principles that have been shown to improve learning from instructional videos. Therefore, this paper seeks to identify principles of video design that are empirically supported in the literature. A systematic literature review was conducted, with a final analysis of 113 papers describing 28 principles. While some of the existing cognitive theory of multimedia learning principles, notably coherence, segmenting and learner control, have been found to improve learning from instructional videos in a variety of contexts, others, such as redundancy and modality, are not supported. These findings serve as clear guidance to instructional designers creating educational video content. In addition to describing the breadth of research in the field, this paper also found that the development of the research field suffers from a lack of coherence and is in urgent need of clear nomenclature and improved reporting of media and research design.
Implications for practice or policy:

Instructional videos that are shorter, segmented, coherent and paired with learning activities are more likely to lead to improved learning gains in students.
Researchers reporting on the use of videos should provide comprehensive descriptions of media, including links to the media where possible.
Designers of instructional videos should critically evaluate design principles established for non-video media.
Taxonomies of technological knowledge in higher education: A mapping of students’ perceptions
Authors: Staddon Rachel
Published: May 2022

This paper presents the findings from a qualitative study exploring students’ perceptions of what constitutes technological knowledge. Technological knowledge dimensions from previous literature do not seem to be student-led, but rather suggested by the authors. It is therefore important to incorporate student views in order to create a more evidence-based taxonomy. Previous taxonomies of technological knowledge are also heavily linked to engineering-related disciplines, however definitions for use across the field of education and learning technologies would be helpful. In this study, a sample of student volunteers were interviewed about their understanding of technology enhanced learning and technological knowledge. The students were from a range of disciplines, not just engineering and science, so that technology knowledge for the general student population would be represented. An inductive thematic analysis was then carried out on the interview transcripts. Three knowledge types were derived from the thematic analysis: practical knowledge; structural knowledge; and computer science knowledge. These three empirically-derived technological dimensions were then mapped onto existing taxonomical structures from the literature. Finally, this paper discusses the implications of the student-generated dimensions for educators.
Implications for practice or policy:

Educators may need to consider how student-generated types of technological knowledge map onto existing technological knowledge structures and Bloom’s taxonomy.
Educators can use the types of technology knowledge to target their teaching to their learners’ required knowledge level.
Nondiffusive variational problems with distributional and weak gradient constraints
Authors: Antil Harbir , Arndt Rafael , Rautenberg Carlos N. , Verma Deepanshu
Published: May 2022

In this article, we consider nondiffusive variational problems with mixed boundary conditions and (distributional and weak) gradient constraints. The upper bound in the constraint is either a function or a Borel measure, leading to the state space being a Sobolev one or the space of functions of bounded variation. We address existence and uniqueness of the model under low regularity assumptions, and rigorously identify its Fenchel pre-dual problem. The latter in some cases is posed on a nonstandard space of Borel measures with square integrable divergences. We also establish existence and uniqueness of solution to this pre-dual problem under some assumptions. We conclude the article by introducing a mixed finite-element method to solve the primal-dual system. The numerical examples illustrate the theoretical findings.

This article validates the operational effectiveness of a fuzzy-based multistage cascaded proportional integral derivative fractional filter (PIDFN) controller which enhances the frequency regulation of an interconnected islanded microgrid system. The effect of the ambiguous nature of renewable energy resources and test cases concerning different load variations are applied to verify the robustness of the proposed controller. The superiority of the proposed controller upon proportional-integral-derivative (PID), fractional-order PID (FOPID), and Fuzzy FOPID controller in minimizing frequency alteration has been verified through MATLAB/SIMULINK environment.

Asthma, the respiratory disorder associated with bronchial hyper-responsiveness, affected 300 million people across the globe, with a prevalence of 4.05% in Saudi Arabia and causing 61.6% of hospital emergency room annual visits. Increased side effects of conventional drugs demand the necessity for the development of natural drugs. In this study, an herbal composite from Bacopa monnieri and Euphorbia hirta was prepared and characterized by Fourier transform infrared spectroscopy (FT-IR) and gas chromatography-mass spectrometry (GC-MS) analysis. In vitro bacterial inhibition and anti-asthmatic activity were evaluated using animal models. Ethanolic herbal composite (EHC) showed significant anti-pathogenic activities. GC-MS analysis identified potential bioactive compounds and FT-IR analysis revealed functional groups corresponding to plant composites. The EHC increased the preconvulsive time against 1% histamine aerosol compared to control animals. In sensitized + EHC-treated animals, total leukocyte, eosinophil, lymphocyte, neutrophil, and monocyte counts were found to be reduced as compared to sensitized and control groups. EHC decreased malondialdehyde and bicarbonate levels denoting the reduced oxidative burden and increased the antioxidant activity by increased intracellular glutathione (GSH) level. The EHC-treated group showed decreased inflammatory cell infiltration compared to the sensitized. A significant anti-asthmatic effect was observed in the EHC-treated group (P < 0.05). Thus, herbal composites are used in the treatment of asthma and can be used as an alternative to commercially available pharmaceutical drugs.
The sound symbolism of food: the frequency of initial /PA-/ in words for (staple) food
Authors: Joo Ian
Published: May 2022

In different languages around the world, morphemes representing the (cooked form of) staple food or food in general tend to begin with a [+labial] phoneme followed by a [+low] phoneme (/pa-/, /ma-/, /fa-/, /wa-/, etc.). This article provides evidence for this phonological similarity by analyzing 66 sample languages’ morphemes representing the staple food within the society where each language is spoken. About a fourth of the morphemes referring to staple food begin with a [+labial] first phoneme followed by a [+low] second phoneme, which is a much higher proportion compared to another list of basic morphemes in the same 66 languages. I further argue that the motivation for this crosslinguistic tendency is the iconic association between the mouth-opening gesture and the concept of eating.

In order to prioritize the conservation and management efforts to protect jaguars (Panthera onca), it is of utmost importance to determine their tolerance in face of human disturbances, habitat modifications and varying degrees of prey availability. We assessed the occupancy probability of jaguars and five of their most common prey species throughout a heterogeneous landscape in the Selva Maya in southern Mexico: armadillo (Dasypus novemcinctus), coati (Nasua narica), paca (Cuniculus paca), white-tailed deer (Odocoileus virginianus), and collared peccary (Dicotyles tajacu). Additionally, we projected prey and Jaguar occupancies onto a 5993 km2 landscape based on the habitat type in the area. We averaged the best prey models ranked by QAICc and found that white-tailed deer had the highest average occupancy probability of 0.72 ± 0.06 and paca the lowest with 0.14 ± 0.04. The average occupancy probability for jaguars was 0.35 ± 0.07 and the strongest predictor of jaguar occupancy was a positive effect of collared peccary occupancy. These findings support previous studies that show that predator distribution is largely influenced by their prey availability, even in the midst of degraded habitats, and underlies the essential need to incorporate protection plans for prey species in jaguar conservation strategies.

God-Guided Contract and Scriptural Sovereignty
Authors: Sashalmi Endre
Published: May 2022

The study intends to examine the two related concepts of contract and sovereignty which (practically unknown in Muscovite Russia) are commonly referred to as proofs of dominance of western concepts in PVM. By examining these concepts in the text I try to point out the Muscovite legacy of the argumentation. I claim that the contract of government between the people and the ruler contains the Muscovite idea of God acting through the people ("the will of the people is the will of God" — the crucial premise legitimating succession both in 1598 and 1613 in official documents) while the concept of sovereignty is predominantly justified by traditional references to the Bible and not so much by arguments taken from western political theory.
The Pozsony Toll Exemption in the Angevin and Sigismund Eras
Authors: Kovács Viktória
Published: May 2022

This study examines the question of the toll exemption of the citizen of Pozsony (Bratislava, Slovakia) in the Angevin period and under the rule of Sigismund of Luxembourg. Beyond interpreting the privilege guaranteed in the town charter issued by Andrew III in 1291, we discuss the problems connected to the validity of the privilege. The town charter ensured the Pozsony hospites the toll exemption in the entire kingdom, but only those could benefit from the privilege who travelled with the purpose of trade. Through royal confirmations, the country-wide toll exemption remained in effect throughout the Angevin and Sigismundian periods. All the lawsuits with known outcome ended with the acknowledgement of the exemption from tolls of the burghers of Pozsony except one case: in 1357 the cathedral chapter of Esztergom managed to break the privilege of the exemption with reference to the ancientness and pious donation of their right to collect tolls. Mentions from the reign of Louis I, however, also imply the existence of a lost but partially reconstructed charter issued by Charles I, which granted the Pozsony townspeople a regionally restricted toll exemption. The latter charter of privilege seems to have provided toll exemption for any kind of traffic, meaning transport of persons and goods on the Pozsony–Visegrád and Pozsony–Buda routes (meaning, the routes to the royal court) on and beside the Danube. Charles’s charter providing a ‘Danube toll exemption’ was probably confirmed by Louis, because court records indicate that the privilege was in effect.
The Role of Trial by Poison in the Representation of the Power of the Luxembourg Dynasty
Authors: Horváth Illés
Published: May 2022

The paper uncovers the role of trial by poison in the representation of the power of the Luxembourg dynasty. After the death of Emperor Henry VII, the contemporaneous sources reported poisoning a few days after the Emperor had passed away, with a great outrage. In my study, I intend to explore how the death of Henry VII affected the dynastic memory and the representation of the family. Furthermore, I also intend to focus on how Holy Roman Emperors Charles IV and Sigismund of Luxembourg reflected on the attempts on their lives and what was the role of trials by poison in their representation of power.
