Semiophores in Multimodal Communication: Verbal and Visual Representation of Cultural Values. Soviet and British Candy Wrappers of the Latter Half of the 20th Century as a Case Study
Authors: Vetrova Kristina O. , Mishlanova Svetlana L.
Published: January 2022

The article considers complex semiophore analysis of Soviet and British candy wrappers representing social and cultural development of Soviet and British society in a certain period of time. Examination of non-trivial research material, definition of the term semiophore and the development of a complex method of semiophore analysis make the presented research relevant. Semiophores are indicated by the authors as derivative multimodal semiotic objects that represent historical, political and cultural identity in different ways. The authors have examined 53 candy wrappers, among which 30 candy wrappers are of a Soviet and 23 ones are of a British origin. All of them were produced in late 20th century. Candy wrappers being semiophores are considered as a complex of associated, functional, pragmatic, logical and semantic connections. This causes a necessity to develop a complex methodology of semiophores analysis. As a result, a complex method of semiophore analysis has been elaborated. The method has been applied in research of Soviet and British candy wrappers of the latter half of the twentieth century. The authors have concluded that in most cases the verbal and visual components that form the structure of a candy wrapper correspond to each other and actualize the image presented on it. All images presented on the Soviet wrappers can be thematically divided into various groups, for example, some candy wrappers represent crucial historical events, literary characters, cultural phenomena and architectural objects of Russian cities. In general, the images presented on the Soviet candy wrappers perform an educational function, contribute to the formation of cultural, national, political identity and self-identity of Russians. British candy wrappers are characterized by a simple design and usually present the name and look of the product. At the same time, the name of a product has a clear structure and informs the consumer about the manufacturer and the content of the product. Unlike the Soviet candy wrappers, the British candy wrappers were found to be primarily aimed at providing product information and advertising the product. The authors are eager to apply the developed complex methodology to the analysis of other types of semiophores in their further research.

Published: January 2022

The work is devoted to the origins and peculiarities of zodiac signs in the ancient Chinese tradition. The study is carried out within the frames of linguocultural approach towards interpreting animalistic metaphors, namely, the zoonyms of the twelve zodiac signs which in China, are used to characterize people concerning their date of birth and are passed on from generation to generation. Chinese zodiacs are based on the astronomic theory of constellations and human worship (idolatry) of totems. It focuses on the comparison of zoonym metaphors reflected as Chinese zodiac signs both in the Chinese and Russian languages proceeding from the theory of metaphor in modern cognitive aspect to detect similarities and differences, and as well, the study of cultural roots of zoonym metaphors revealed in the Chinese zodiac signs. The object of the study concerns zoonyms of zodiac signs possessing the relevant meaning in the Chinese zoological lexis. The work elaborates the definition of the notion zodiac, describes the processes of the genesis, formation and development of the Zodiac culture and its specific cultural relevance; according to the analysis undertaken, the means to differentiate twelve animals of the Chinese Zodiac, and those of Chinese fairy tales, on the one hand, and, on the other hand, in Russian - animals were discussed and verified as to I.A. Krylovs fables. The conclusion states that metaphors are determined by the language itself, and linguocultures of various nations are reflected in specific metaphors and other peculiarities.

16 anos da Lei de Biossegurança (Lei n. 11.105/2005): a utilização de células-tronco embrionárias para fins de pesquisa e terapia e o status moral do embrião pré-implantatório
Authors: Carvalho Gisele Mendes de , Ishikawa Vítor De Souza
Published: January 2022

A Lei n. 11.105/2005 tornou permitida a utilização de células-tronco embrionárias para fins de pesquisa e terapia, desde que cumpridas determinadas condições, conforme dispõe seu art. 5º, I e II. Coube investigar se o embrião pré-implantatório goza de status moral de pessoa humana, se se classifica como coisa (patrimônio) ou tão somente como um ser integrante da espécie humana, merecendo ou não, desde sua concepção, tutela jurídica. Utilizou-se o método de abordagem dedutivo, com análise da legislação e de pesquisa bibliográfica. Os resultados concluem que, embora o embrião pré-implantatório não se classifique como “coisa”, uma análise ontoaxiológica afasta um suposto status de pessoa humana, não havendo violação a seus “direitos” em pesquisas que envolvam o uso de células-tronco embrionárias.
Combined assurance — A potential integrated governance option for SMEs?
Authors: Ulrich Patrick
Published: January 2022

Against the backdrop of recent corporate scandals, but also due to increasing digitalization, the discussion about integrated approaches to corporate governance under the umbrella term of combined assurance (CA) is gaining in importance. Whereas this has so far been considered increasingly from the perspective of internal auditing, this article supplements the ideas of integrated corporate governance with an explicit view of compliance management in medium-sized companies. It is based on an empirical study of 141 companies conducted by the Aalen Institute for Corporate Management (AAUF) in 2021. The study compared, among other things, the three lines of defense (TLoD)/three lines (TL) approaches of the Institute of Internal Auditors (IIA) and the combined assurance approach, which are widely used in the literature.

Authors: Otman Khaled
Published: January 2022

This paper focused on the concept of corporate governance based on shareholders’ and stakeholders’ perspectives and the development of corporate governance around the world, including the UK, the US, and Australia. The OECD Principles of Corporate Governance were presented, including shareholders’ rights, the equitable treatment of shareholders, disclosure and stakeholders’ rights and transparency practices, and the responsibilities of board of directors. Numerous corporate collapses have highlighted the call for the management and directors of companies to be more accountable, and they have led governments and international organisations such as the OECD to be more active in establishing principles of corporate governance. It was concluded that the system of corporate governance has increased in different countries in relation to the nature of the economy, legal systems, and cultural norms
Apprenticeship Indentures and Apprentices in Medieval England, 1250–1500
Authors:   , Sandy Rhiannon E.
Published: January 2022

This thesis uses apprenticeship indentures to offer a novel insight into guilds and apprenticeship in medieval England. Indentures offer a unique view of idealised master-apprentice relationships, which are otherwise only visible in official records. A collection of 82 surviving indentures forms a starting point for exploring social, economic, and legal aspects of apprenticeship in medieval England, both within and outside the guild system. Chapter 1 outlines the content of indentures and provides a guide to their general form. Indentures developed gradually in response to social, economic and legal factors; these are explored in subsequent chapters. Chapter 2 discusses the enforceability and enforcement of legislation pertaining to apprenticeship, as well as exploring the legal complexities of indentures as binding legal agreements made by minors. Chapter 3 considers apprenticeship in three ways in the context of the guild system: as a means of exploitation, as a means of exclusion, and as a means of providing technical training. No single model prevails, but the influence of each depends on geographical, economic, and temporal factors. Subsequent chapters provide an overview of the reality of apprenticeship. Chapter 4 discusses the use of behavioural clauses in indentures, which controlled apprentices’ behaviour with the primary aim of protecting masters’ reputations. Chapter 5 explores apprentices’ expectations of the apprenticeship, including provision of training. Chapter 6 presents novel estimates, based on surviving records, of the cost of maintaining an apprentice, concluding that they were not ‘cheap’ labour. Historians have not previously considered this cost. Chapter 7 uses testamentary evidence to examine close master-apprentice relationships, highlighting the importance of fictive kinship. Civic enfranchisement and its relative importance is also discussed. Overall, this thesis provides an original survey of apprenticeship in medieval England, based mainly on evidence from a previously neglected document type.

Published: January 2022

Effects of inclination and free convection on velocity profile for magnetohydrodynamic (MHD) fluid flow in an inclined cylindrical pipe has been investigated. The governing partial differential equations are the equations of continuity, momentum and energy which are converted into ordinary differential equation by employing similarity transformation and solved numerically by the Runge- Kutta fourth order scheme with shooting method. The findings, which are presented in the form of tables and graphs reveal that; when Hartmann number, Grashoff number and Gamma are decreased, the velocity of the fluid increases. The results of the study may be useful for the different model investigations, especially, in various areas of science and technology in which optimal inclination and free convection are utilized.

Published: January 2022

The demand for electrical power is rapidly increasing due to the rise of industries in developing countries. Power generation stations are having troubles to strike a balance between demand and generation. In this situation, it is urged that appropriate remedial action be taken. Rising power demand can be met by designing an efficient electric power generation system which will also help lowering the generation cost. It is shown that while high rated electric power generators are connected in parallel the value of neutral current is rising and the cooling temperature is also increased. Here, the goal of this experimental work is to present a new model for designing an efficient power production system for average-load (ranging up to 8000 Amp, 440 V) industries to minimize the demand on centralized interconnected grid. A scheme is proposed with four generators (2500 kVA, 2000 kVA, 2000 kVA and 1250 KVA) in parallel and enough cooling arrangement is provided with minimal cost. The coolant temperature is maintained 61 °C to 61.5 °C and at that time diesel temperature is not more than 38.5 °C. The amount of neutral-current is also optimized (up to 8.5 Amp.) which was more than 12 Amp. At the morning and afternoon, the neutral current is almost constant, but it is bit fluctuating between 7.5 Amp to 8.2 Amp at mid-day. The final outcome shows, the suggested system is efficiently stable with the change of load and generates optimal electricity.

More Than a Deadly Virus: COVID-19 and Its Psychological Impact on American and Canadian Dental Practitioners
Authors: Upadhyaya Jasbir D. , Mutalik Vimi Sunil , Lê Mê-Linh , Schönwetter Dieter J.
Published: January 2022

Objectives: The COVID-19 pandemic has significantly affected dental professionals, thus contributing to adverse psychological outcomes. The aim of this cross-sectional study was to investigate the psychosocial state of American and Canadian dental practitioners, with special emphasis on their affective well-being (both during lockdown and after re-opening), behavioral impact and cognitive responses.

Methodology: Dental practitioners in Canada and USA were invited to participate in an online survey after the initial lockdown period. The questions evaluated the pandemic’s effect on affective, behavioral, and cognitive responses.

Results: A total of 587 practitioners completed the online survey. The strongest emotions experienced during the lockdown were sadness followed by fear. Female practitioners, those in the 35-44 age group, and those with less work experience reported higher scores on fear. Following lockdown, participants reported higher anticipation. Males expressed higher feelings of disgust and anger during both phases. Canadians were trustful of the situation in both phases of the pandemic, whereas the emotions of Americans were more towards disgust. About 56.7% practitioners provided teledentistry during lockdown, mainly through video calling, with Canadians being significantly more involved than the American participants. The highest scores for participants’ experiences during lockdown were for a lack of social interaction, followed by concern for contracting infection, and stress from distressing media coverage. Most practitioners were very receptive of receiving the COVID-19 vaccine.

Conclusions: The emotions and behaviors of dental practitioners varied significantly during and after the initial lockdown, highlighting their psychosocial state during the pandemic. The scarcity of literature focusing on these basic emotions during similar outbreaks calls attention for pursuing more research in these areas as they significantly contribute to the overall psychological health of professionals, especially in times of crises. Given the emotions reported by dental practitioners, it would be of value to develop standardized protocols and provide remote psychological support during such periods of uncertainty.
Use Hierarchical Codebook to Improve the Primary User Detection in the Cognitive Radio’s Cooperative Spectrum Sensing
Authors: Tran Hoai Trung
Published: January 2022

Currently, the cognitive network is receiving much attention due to the advantages it brings to users. An important method in cognitive radio networks is spectrum sensing, as it allows secondary users (SUs) to detect the existence of a primary user (PU). Information of probability of false detection or warning about the PU is sent to a fusion center (FC) by the SUs, from which the FC will decide whether or not to allow the SUs to use the PU spectrum to obtain information. The transmission of information with a high signal to noise ratio (SNR) will increase the FC's ability to detect the existence of the PU. However, researchers are currently focusing on probabilistic formulas assuming that the channel is known ideally or there is nominal channel information at the FC; moreover, one model where the FC only knows the channel correlation matrix. Furthermore, studies are still assuming this is a simple multiple input – multiple output (MIMO) channel model but do not pay much attention to the signal processing at the transmitting and receiving antennas between the SUs and the FCs. A new method introduced in this paper when combining beamforming and hierarchical codebook makes the ability to detect the existence of the PU at the FC significantly increased compared to traditional methods.

Published: January 2022

This paper presents the design of a DC microgrid for a remote community in Edo State, Nigeria having a solar irradiance of 4.63 kWh/m2/day. The community is isolated and located far away from the city with no access to the electricity grid. There is a need for lighting and running of electronics, as the main source of lighting presently is kerosine, which is not efficient and leads to health issues. The community is made up of 9 residences that are not more than 100 m apart. House 1 was selected as the standard house with a load of 1 kWh/day, while the other 8 houses have a load difference of ±10% with reference to house 1. Using a 48 V DC bus, the designed PV system components comprise of a 100W solar photovoltaic (PV) panel and a 12 V 45 A·hr battery. The system was sized using Homer Pro. Optimization results presented various design for the various houses. The result obtained showed reasonable and feasible cost-effective solution in terms of the Net Present Cost in both installation and running of the hybrid system for the community. Sensitivity analysis was also carried out to test the adaptability of the system using a solar irradiation input of ±10%. Detailed result of the analysis is presented in the paper.

Published: January 2022

Integrated Nutrient Management (INM) is a novel strategy to achieve sustainable crop production in degraded soils through judicious and balanced plant nutrients utilization. Sole application of chemical fertilizers in crop production causes soil and environmental pollution. The present study was designed to assess the effects of application of organic manures conjointly with chemical fertilizers on growth and yield of okra in acid soil. The experiment was consisted of four treatments viz. T0 [Control], T1 [Recommended dose of chemical fertilizers (RDF)], T2 [Dolomite (D) @ 1t ha-1 + RDF], T3 [Poultry manure (PM) @ 3t ha-1 + RDF], T3 [Cow dung (CD) @ 5t ha-1 + RDF] with six replications in a randomized complete block design. The results indicated that the use of PM with RDF showed better performance in the growth and yield attributes of okra. Compared with others plots, the highest plant height (114.10 cm), fresh weight plant-1 (591.58 g) and dry weight plant-1 (86.73 g) were observed in the PM-treated plot. Similarly, the highest number of fruits plant-1 (20.33) and fruit yield (13.58 t ha-1) were also found in PM-treated plants. Therefore, under acidic soil conditions, organic and inorganic fertilization may have a significant positive impact on the growth and yield of Okra.

Published: January 2022

The study was conducted in Koffikro-Affema village located in the South-East of Côte d'Ivoire to assess the morpho-physical and chemical quality of soils under cocoa farm, for the management of early degradation of orchards. Representative soil samples were taken by horizon under degraded cocoa farms after a morpho-pedological characterisation. These samples were then analysed in the laboratory for fertility parameters. The results indicate that the cocoa farms have a high rate of degradation and the study made it possible to identify the soil characteristics associated not only with the degradation of cocoa trees, but also with the drop in yield. These are the rate of coarse grains greater than 50%, the low organic matter content (less than 3.5%), a very slow rate of mineralisation (C/N > 12), poor internal drainage and the acidic pH of the soil (4.4-5.5). The soils surveyed are highly desaturated to moderately saturated and the main characteristics of the absorbing complex indicate that they are unfavourable for cocoa. Indeed, these soils are deficient in K+ (<0.2 cmol/kg), Ca2+ (between 5.1 and 11.41 cmol/Kg) and assimilable Nitrogen (˂0.2 cmol/Kg). Similarly, the Mg2+/K+ ratio of less than 3 shows that they are magnesium deficient. The results also revealed an influence of the topographical position on the degradation of cocoa trees with, on the upper and middle slopes, strongly gravelly and poorly drained horizons, associated with the degradation of cocoa trees. On the other hand, on the lower slopes, these soils are deep, not gravelly, with good growth of cocoa trees and low yields.

Authors: Ohwo Odafivwotu , Bekeowei R. Alexander
Published: January 2022

Surface water pollution through the discharge of untreated wastewater is on the increase globally. Efforts made using conventional techniques had not yielded the needed results. This study was conducted to determine the effectiveness of some native aquatic plants for the removal of some physico–chemical parameters from car wash wastewater effluents in Yenagoa metropolis. The plants used for this study were lemna minor, nymphaea nouchalli, pistia-stratiotes, eichhornia crassipes and ceratophyllum demersum; while the physico-chemical parameters investigated in this study include pH, DO, COD, BOD5, NO3, PO4 and turbidity. The wastewater samples collected from car wash bays were analysed to determine the level of the physico-chemical parameters concentrations using standard methods. The experiment was conducted in a green house for 42 days retention period. The results indicated that the cultured plants reduced the physico-chemical parameters to a minimum level, except DO, which increased in concentration. Therefore, they are considered good bioremediators of the parameters under review and the bioremediation potentials of the plants are in the order of P. stratiotes > L. minor > E. crassipes > N. nouchalli> C. demersum. It is therefore recommended that these plants should be used to treat wastewater effluents based on the investigated physico-chemical parameters.

Published: January 2022

This study was carried out by using well logs to evaluate the depositional environments and hydrocarbon reservoirs in the Otuma oil field, Niger Delta basin. The gamma motif/model within- study interval in the drilled well shows blocky, symmetrical, and serrated shapes which suggest a deltaic front with mouth bar to a regressive - transgressive shoreface delta respectively. A correlation was done on the well logs across the wells and the ten well logs were used to evaluate the petrophysical characteristics of the reservoirs. The reservoirs showed highly porous and permeable channels where the wells were used for the characterization. The ten reservoirs were mapped at a depth range of 2395 m to 2919 m with thicknesses varying from 4m to 135m. The petrophysical results of the field showed that the porosity of the reservoirs ranges between 0.10 to 0.30, and permeability from 48 md to 290 md; the water saturation ranges from 0.39 to 0.52, and hydrocarbon saturation from the field 0.48 to 0.61.

Introduction: Coronavirus Disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) first appeared in December 2019 in Wuhan, China and has subsequently become a worldwide pandemic. During the pandemic, health care workers (HCWs) were very exposed to COVID-19 infected patients. The aim of this study was to determine seroprevalence of SARS-CoV-2 (COVID-19) among HCWs in three health facilities of Yaounde.

Methods: A cross-sectional study involving 368 HCWs was conducted from January 18th to February 13th, 2021, in three health facilities located in city of Yaounde. Data of study participants were collected by face-to-face interviews using standard questionnaire. Blood samples were collected in labelled dry tubes and analyzed using Rapid Diagnostic Test (RDT) cassettes (Abbott PanbioTMCOVID-19 IgG/IgM Rapid Test Device). The data collected was analyzed using Epi info version 7. Any value of p <0.05 was considered statistically significant.

Results: The average age was 30.25 (SD±10.43) years old, range from 21 to 72 years old. Overall, the positivity rates of IgM, IgG and IgM+IgG were 6.79% (n=25), 17.93% (n=66) and 1.09% (n=4) respectively. Multivariate analysis showed that, the rate of IgM positivity was highest in laboratory personnel (χ2= 7.99, p=0.3) and IgG (χ2= 8.50, p=0.29), IgM+IgG (χ2= 1.92, p=0.26) respectively in pharmacy and clinical personnel. The clinical signs such as fever (˃38°C) or history of fever was statistically significant with IgM (χ2=11.71, p= 0.0006) while, sore throat was statistically significant associated with IgM (χ2= 14.3, p= 0.0008) and IgG (χ2= 6.33, p= 0.04).

Conclusion: The results of this study reveal a high seroprevalence of circulation of the virus in hospital milieu in Yaounde suggesting the continuation of the COVID-19 « Track-Test-Treat » system to break the chain of transmission.
Another Perspective of the Miller Forensic Assessment of Symptoms Test – Part I: A Narrative Review
Authors: Detullio D.
Published: January 2022

Reference [1] presented a skewed perspective of the M-FAST literature base and provided the flawed conclusion that the M-FAST should no longer be used in practice. In an attempt to correct the many issues with [1], this article provides a narrative review of the strengths and weaknesses of research findings for the M-FAST interpretation as well as reviews methodological concepts underlying feigning research. The M-FAST was designed to screen for potential feigning of psychiatric symptoms. It was not designed to conclude that an examinee is feigning or malingering psychiatric symptoms. A positive result on the M-FAST only indicates that additional data needs to be collected to make the aforementioned conclusions. Applying the M-FAST in any other way is a serious error on the part of the user. The research literature thus far generally supports the use of the M-FAST cut-off as a screening measure for possible feigning of psychiatric symptoms. However, there are scenarios when the M-FAST may not operate as efficiently, and these scenarios are discussed. Reference [1] misrepresented the purpose of the M-FAST as well as research findings on the M-FAST. Therefore, [1] should be read with great caution.
Epidemiology and Vaccine Efficacy of Delta Variant
Authors: Naji Hassan
Published: January 2022

Several variants of concern (VOCs) of SARS-CoV-2 have emerged after its first outbreak in 2020. These VOCs possess mutations in the spike protein that confers enhanced rate of infection and transmission of these VOCs. Among these VOCs, the delta/B.1.617.2 variant was identified in late 2020 in India and soon spread to several countries around the globe. Currently, it is the most widely sequenced variant among new infected individuals with SARS-CoV-2 infection. This variant is also found to be associated with COVID-19 infection in vaccinated individuals, but the severity of disease and rate of hospitalization are low among these individuals as compared to unvaccinated individuals. With the emergence of new variants of SARS-CoV-2 due to continuous mutations, it is suggested that vaccination plays a significant role in preventing the transmission of disease and disease severity.
