Arguing Spanish voseo tuteante verb endings: learning, variation and history with OT
Authors: Vázquez-Larruscaín Miguel
Published: February 2021

The full historical trajectory of voseo (second plural) forms becoming (deferent) second singular forms — as in Latin vos amātis (2pl) > Medieval Spanish vos amádes (2sg formal) — is a central chapter in the history of Spanish. In many Latin-American Spanish vernaculars, classical voseo fused with the original tuteo, giving rise to a new neutral address paradigm, voseo tuteante (Pre-classical Spanish voseo: vos amádes, amáes, amáis, amás (2sg formal) > Latin-American Spanish voseo tuteante: vos amáis, amás (2sg informal)). After a process of selection from the available options, four sets of endings have survived in those varieties: (áis, éis, ís / ás, és, ís / áis, ís, ís / ás, ís, ís). Why these four? The analysis proposed here builds on global properties of the verb system: (i) the verb suffix -is definitively replaced -des in the second half of the XVII century and the early XVIII century, and (ii) the four sets of endings now extant are exactly the ones that can be learned by Optimality-Theoretic grammar-inductive algorithms. This analysis supports the generative view that only languages with learnable grammars are passed on to future generations. Unlearnable languages are most likely to be lost over time. Similarly, variation is also constrained by the limits set by learnability conditions.
Force parameters of metal deformation during sheet drawing
Authors: Morozov Yury A.
Published: February 2021

The aim of the work. The effect of the curvature of the rounding of torus surfaces during the formation of a cylindrical product (glass) is investigated, taking into account the plastic thinning of the deformable material at the end edges of the matrix and pressing punch. Methods. The existing scheme for determining the power parameters of sheet drawing is analyzed, based on the assumption of the implementation of some abstract stress state in the material; mainly conditional tensile strength. At the same time, the possibility of forming the product without destruction determines the obvious overestimation of the stress level. A mathematical model of the volumetric stress state of the metal is being developed, which makes it possible to assess the deformation and stress state during the formation of a cold-drawn product, i. e. the folding of the sheet blank along the end radius of the rounding of the pressing punch and the steady-state process of drawing the blank into the deformation zone with successive bending/straightening of the material along the edge of the matrix are considered. The level of radial stresses during folding and stretching of sheet material is estimated, taking into account its strain hardening and thinning, which determine the forming force. The obtained results will make it possible to simulate the stress-strain state of the metal during the development of sheet drawing technology: to establish the amount of thinning, to estimate the level of radial stresses in the formation of rounding of torus surfaces along the end edges of the matrix and the pressing punch, as well as to determine the power parameters of the formation, which will prevent the destruction of the pulled part, guaranteeing obtaining high-quality products and more accurately choosing the deforming equipment.
Some peculiarities of the polarization structure of the electromagnetic field at high frequencies in geological sections: mathematical solutions and experiments
Authors: Abramov Vladimir Yu.
Published: February 2021

The effects of induced polarization (IP) in the ore bodies and host rocks in the frequencies above 1 000 000 Hz were considered. The phase response of the complex resistivity (CR) system equipment Geozond have been explored instrumentally. The reliability of high-frequency IP measurements was confirmed by independent verification by mining activities. The results confirm the presence of IP effects in the ore bodies and host rocks. They suggest the necessity to account for IP effects in the interpretation of electromagnetic data, in particular, in induction logging data. The purpose of mathematical computer modeling in this work was to study the propagation of a high frequency electromagnetic field from a linear current source in a material medium by solving Maxwell's equations using finite-difference approximations (iterations) in the time domain. The measurement results were processed according to a well-known scheme, using the method of iterative selection in automatic mode. This allows to use this method for end-to-end calculation of electromagnetic fields in complex three-dimensional inhomogeneous structures.
Development of a design methodology for heat-loaded dimensionally stable elements of carbon plastic construction for a remote sensing of the Earth space equipment
Authors: Gorodetskii Mikhail A. , Mikhaylovskiy Konstantin V.
Published: February 2021

One of the most important tasks of the Federal Space Program of Russia for the period until 2025 is the creation of spacecraft for remote sensing of the Earth. An integral part of the design of this class spacecraft is the determination of the parameters of the orbits that are most effective from the standpoint of information content, energy supply and the duration of active existence. In orbital flight, the temperature state of spacecraft in a complex way varies in time and space. The inhomogeneous temperature field of the structural elements of spacecraft can cause shape distortion, which adversely affects the performance of targets. A technique for a comprehensive analysis and determination of the platform composite design parameters, which is part of the spacecraft for remote sensing of the Earth is proposed. The conditions of thermal loading for flight in a sun-synchronous orbit are considered and mathematical modeling of the operating conditions that ensure the effective operation of such spacecraft is performed. The results of modeling the thermal regime of options for composite platform designs are presented. The technique will be useful in determining the complex of orbital characteristics of the Earth remote sensing satellite at the stage of technical proposals.
Educational Experiences of Adolescent Mothers while Studying College in the Philippines
Authors: Gatbonton Ryan Ray G.
Published: February 2021

Adolescent pregnancy is a significant societal issue that results in lost opportunities for teenage girls in both developed and developing countries. This phenomenological research study explored the lived experience of adolescent mothers during their college years. Eight participants were asked, via unstructured interview, to share their experiences as college students in the midst of pregnancy. Data was analyzed using Collaizi’s method, while member checks and expert audits of interview outputs were done to ensure trustworthiness. Results show that the participants went through several stages in their plight: they faced the complexities of adolescent pregnancy alongside college education; dealt with life and educational conflicts; appreciated the importance of education; found the resolve to carry on for their child; and dreamt of a better future for their families. These findings were clustered into themes and related to Parson’s Adaptation, Goal Attainment, Integration, and Latency theory, as adolescent pregnancy paved the way for teenagers to assimilate society’s expectations of responsible adulthood. Consistent with academic literature, the participants’ experiences show that adolescent mothers are vulnerable in the education setting, and need proper guidance to achieve their full potential. This research can serve as groundwork for initiating several educational reforms. A multicomponent intervention program was developed that is rooted in school and community partnerships.
Exploring Implementation of National Special Needs Education Policy Guidelines in Private Secondary Schools
Authors: Mbewe Gift
Published: February 2021

The implementation of the National Special Needs Education Policy Guidelines in Malawi began in 2009. There is limited literature on how the guidelines are implemented in secondary schools, particularly in private secondary schools of Malawi. Therefore, the study aimed at exploring the implementation of the guidelines in private secondary schools. The study used a phenomenological design and qualitative methodology. Data were generated through a triangulation of methods including semi-structured interviews, observation and document analysis. The data generated were analysed thematically. The findings revealed that there was a lack of thorough knowledge of the guidelines, resources for implementing the guidelines in private secondary schools were not available, and support for learners with special education needs was not sufficient. The results of this study indicate that communication with key school stakeholders is key for the effective implementation of the National Special Needs Education Policy Guidelines.
Kipper and the corpse
Authors: Stuart Whipps
Published: February 2021

‘The Kipper and the Corpse’ (TK&C) borrows its title from an episode (March 1979) of the sit-com Fawlty Towers. Whipps’s TK&C research draws attention to both the social changes wrought by Thatcherism and prevailing media attitudes of the time. 1979 was pivotal for UK manufacturing as the then conservative government sought to undermine labour unions. Against this historical backdrop, the project raises questions about how the living memory of the pre-neoliberal world can be accessed and re-engaged with to bring about a collaborative understanding of present-day discourses around the politics and economics of labour. TK&C also offers a novel approach for paticipative creative activity, inverting the more normal artist-led working method.

TK&C is a unique community-based art project that included the restoration of a 1275GT Mini made in Longbridge in 1979. Through the process of restoring the car, Whipps worked with several Longbridge ex-employees with car production and engineering expertise, social historians, sociologists, and anthropologists. These participants brought specialist knowledge and vocational skills to bear, positioning the artist/researcher, Whipps, as the novice. This reversal of roles destabilised the standard researcher - participant relationship allowing for the emergence of more participative forms of knowledge production and transfer. This form of collaboration encouraged multiple audiences, from beyond the art world, to engage with the underlying context used by the project.

The practical outcomes of TK&C were augmented by information gathered from records at Warwick University, British Motor Museum archives, oral histories, media representations of British Leyland (sitcoms, political cartoons, tabloid newspapers) and photographic documentation.
The project has been supported by Longbridge Public Art Project (LPAP) and featured in contemporary art exhibitions, including touring venues such as the British Art Show 8 (2015-2017), the IKON Gallery (2019), and internationally at Fabra i Coats: Contemporary Art Centre of Barcelona (2020).
FROM THE RELIGIOUS STAGE TO THE POLITICAL STAGE: TEUNGKU DAYAH'S POLITICAL COMMUNICATION STUDY IN ACEH
Authors: Muntasir Muntasir , Aminullah Muhammad
Published: February 2021

This paper describes the Teungku Dayah political communication model in maintaining the harmony of Muslims in Aceh. Political turmoil in society often creates unrest, as it separates religious and political values. On the other hand politics is actually very instrumental in the development of Islam in Aceh. Teungku Dayah is the main actor and key figure in political development in Aceh. As a public figure, Teungku Dayah has a stake in the mass vote in the regional elections, the president and other political contests. This research is an analysis of the phenomenon of Teungku Dayah's political role in maintaining the harmony of the people. The technique of data collection used was direct observation, and the data were analyzed by describing the actions of Teungku Dayah's political role. The research concludes that Teungku Dayah has its own system and character in guarding Aceh's political development. He uses the Islamic boarding school and the dayah institutionas media for political communication. But the shift in values in instant politics makes Teungku Dayah's political communication power limited to front stage politics. Further research is necessary on political communication in Teungku Dayah, since political communication is a dynamic study, as dynamic as the conditions in Aceh.

COMPARISON OF THE EFFECTS OF TWO DIFFERENT ANTIOXIDANT COMBINATIONS ON SPERM PARAMETERS
Authors: Yariş Mehmet , Akdogan Nebil , Ozturk Murat , Bozkurt Aliseydi
Published: February 2021

Male infertility may be the result of some identifiable conditions
(varicocele, cryptorchidism, hypogonadism, and genetic abnormalities),
but there is no identified cause in 30-40% of infertile men. Studies
show that the use of antioxidants has a beneficial effect on fertility,
especially on sperm quality, and therefore recommended as a potentially
effective treatment for male infertility. However, it is argued that
this treatment is not based on sufficient evidence and has no effect on
the rate of healthy pregnancy. Aim: In this study, two different
antioxidant combinations with different doses and contents were
evaluated in terms of their effect on sperm parameters. Materials and
Methods: A total of 122 patients diagnosed with idiopathic infertility
were enrolled in our multicenter study. The patients were divided into
two different groups: The first group used Proxeed Plus sachets 2x1 and
the second group used Carniact Duo tablets 2x1 for six months. The total
semen volume, total sperm count and concentration, motile sperm count,
and morphological findings of the patients were compared at the end of
the six months. The mean age of the patients participating in the study
was 30.8 ± 6.05 years. No significant difference was found between the
two groups in terms of baseline sperm count. Results: There was a
significant difference between the baseline and sixth-month values of
the patients using both combinations. However, no significant
statistical difference was found between the groups according to the
sixth-month data. Conclusion: The combinations of both antioxidants had
a positive effect on sperm parameters, and the use of different doses
and contents had a similar effect. Keywords: Antioxidants, Infertility,

High-doses vitamin C improves cardiac injury through attenuating hyperinflammation in COVID-19
Authors: Xia Guozhi , Fan Di , Ma Chaoran , He Yanru , Zhu Yaohu , Zheng Qiangsun
Published: February 2021

Background: Cardiac injury is common and associated with worse clinical
outcomes in COVID-19. Data are lacking whether high-dose intravenous
vitamin C (HIVC) could help to improve cardiac injury in the pandemic.
Methods: The study included severe and critically ill COVID-19 with
cardiac injury. Troponin I and inflammatory markers were collected at
admission and 14 days after treatment with HIVC along with symptomatic
supportive treatment from the electronic medical records. Results: The
patients (n = 113) were categorized into the improved cardiac injury
(ICI) group (n = 70) and the non-improved cardiac injury (NICI) group (n
= 43). Overall, 51 (45.1%) patients were administrated with HIVC, the
percentages of patients with HIVC were higher in the ICI group than
those in the NICI group. Logistic regression analysis revealed that HIVC
was independently associated with improved cardiac injury. Further
analysis showed that inflammatory markers levels significantly decreased
at 14 days after treatment with HIVC compared to those without HIVC.
Meanwhile, similar results were also observed regarding changes in
inflammatory markers levels from baseline to 14 days after treatment
with HIVC. Conclusions: HIVC can improve cardiac injury through
attenuating hyperinflammation in severe and critically ill patients with
COVID-19.

Published: February 2021

Background: Atrial fibrillation (AF) and venous thromboembolism (VTE)
share several risk factors related to arterial thromboembolism. No study
has reported the differential contribution to arterial thromboembolic
events and mortality between these two conditions in the same
population. Methods: We included AF and VTE national cohorts derived
from Taiwan National Health Insurance Research Database between 2001 and
2013. The eligible population was 314,861 patients in the AF cohort and
41,102 patients in the VTE cohort. The primary outcome was arterial
thromboembolic events, including ischemic stroke, extracranial arterial
thromboembolism (ECATE) and myocardial infarction (MI). Secondary
outcomes were all-cause mortality and cardiovascular death. Results:
After a 1:1 propensity matching, 32,688 patients in either group were
analyzed. The risk of arterial thromboembolic events was lower in the
VTE cohort than that in the AF cohort (subdistribution hazard ratio
[SHR], 0.60; 95% confidence interval [CI], 0.57–0.62)). The
risk of ischemic stroke (SHR, 0.44; 95% CI, 0.42–0.46) and MI (SHR,
0.80; 95% CI, 0.72–0.89) were lower in the VTE cohort, while the risk
of ECATE (SHR, 1.23; 95% CI, 1.14–1.33; particularly lower
extremities) was higher in the VTE cohort. All-cause mortality rate was
higher in the VTE cohort (HR, 1.18; 95% CI, 1.15–1.21) while the risk
of cardiovascular death was lower in the VTE cohort (HR, 0.96; 95% CI,
0.93–0.995). Conclusions: Patients with AF had higher risks of arterial
thromboembolic events compared to patients with VTE, despite having risk
factors in common. The VTE cohort had higher risks of all-cause
mortality and ECATE, particularly lower extremity events, compared to AF
patients. These differential manifestations of thromboembolism sequelae
in AF and VTE merit further investigation.

The development of small towns in Latvia is strongly affected by the growth of the tourism industry. New tourism products and sightseeing objects are created to develop local tourism and increase the number of visitors to cities/regions owing to municipal support. It has been found that in artisanal quarters, product sales and educational masterclasses create a new added value for tourism, thereby contributing to the sustainable development of the area. The first part of the research explained the role of crafts and artisans in urban development. The second part of the research performed a comparison of the operational patterns of current houses and centres of crafts, conducted an expert survey of administrators of the houses and centres of crafts and identified the demand for artisan products by the population and their interests in the development of the Jelgava Old Town street quarter. The research has concluded that in order for crafts to survive, national and local government support is needed for creating houses, centres, quarters and streets of crafts, improving the infrastructure for artisans to work and for tourists to visit them. Municipalities need to develop and implement a policy and a programme for craft development. Crafts have transformed into the cultural industry and in many autonomous communities, the craft competences have merged with tourism and contributed to a broad supply of products and have become important for the development of the area. Overall, the number of visitors to some Jelgava city tourism facilities increased in 2018, yet the total number of visitors decreased. This indicates that the city needs new local tourism facilities. Four operational patterns of houses and centres of crafts were identified in Latvia. Crafts as an important and supportive activity to be developed are incorporated in a number of European, national, Zemgale planning region, Jelgava city and region development strategies and programmes, thereby emphasizing the support needed for traditional artisan activities. Respondents highly rated the need for a house of crafts in the Jelgava Old Town street quarter – 45% expressed very convincing opinions, while 42% rated it as average. The main benefits in the context of craft functions pertain to the cultural and historical heritage and social value. Further research studies are needed to analyse the economic and creative/innovative functions of crafts.
Classifying Restatements: An Application of Machine Learning and Textual Analytics
Authors: Hayes Louise , Boritz J. Efrim
Published: February 2021

Restatements of audited financial statements are used for evaluating reporting quality and audit quality, and for other evaluative purposes. We constructed a machine learning algorithm to classify restatements by management intent based on the language in restatement announcements. Our machine learning classification is as reliable as other commonly used automated methods such as those based on market reaction, restatement direction, and magnitude. Our method does not require a dictionary of words and is applicable when other automated methods are not, for example, when restatements are announced contemporaneously with financial results and when net income is not restated. For large samples, the use of such a classification algorithm is less tedious and less time-consuming, and more consistent, replicable, and scalable than manual classification.

How Does SEC Review Correspondence Affect Investors' Judgments? The Role of Access Costs and Review Ambiguity
Authors: Gale Brian
Published: February 2021

Review correspondence between the SEC and firms is a potentially valuable resource for investors, revealing important information about firms' financial reporting quality. Research suggests that reducing access costs (i.e., the amount of effort required to access review correspondence) could increase investors' processing of this important information. Drawing on psychology theory, I predict and find that access costs interact with another key characteristic within the SEC's control—review ambiguity (i.e., transparency about outcomes from the SEC's review process)—to influence investors' judgments. Results show that when access costs are low, greater review ambiguity decreases investors' reliance on review correspondence information and influences investment judgments in a corresponding manner. In contrast, review ambiguity has no effect on investors' reliance or investment judgments when access costs are high. Overall, my results provide important new insights on the importance of SEC transparency during its review process, particularly as information becomes more easily accessible.

Sei es die Suche nach Heimat und Identität in der scheinbar grenzenlosen Weite der Wüste (Lawrence of Arabia, 1962), die Flucht in die Stille der eiserstarrten Weite Russlands (Dr. Zhivago, 1965), der kollektive Widerstand im unbekannten Birma (The Bridge on the River Kwai, 1957) oder die verstörende Konfrontation mit sich selbst in der Fremde des polyphonen Indiens (A Passage to India, 1984) – Leans Filme, ihre Bildästhetik, aber vor allem ihre Geschichten von Begegnungen mit fremden Welten und unbekannten Kulturen, von teils privaten, teils großen Abenteuern sind bis heute unvergessen. In Erinnerung geblieben ist vor allem ihre bildgewaltige Erzählweise: großformatige Kameraeinstellungen wie die der purpurrot aufgehenden Sonne über der arabischen Wüste; das bizarr-romantisch verschneite Anwesen in Varykino oder die effektvolle und symbolträchtige Brückensprengung durch den tödlich verwundeten Nicholson – Bilder, die sicherlich nicht nur die Kinoästhetik ihrer Zeit revolutioniert, sondern auch auf der Cinemascope-Leinwand den Zuschauer gefesselt und begeistert haben. Die Arbeitsthese dieser Arbeit ist, dass sich die Filme von David Lean über immer wiederkehrende Erzählmuster beschreiben lassen, bei denen ‚Räume‘ eine wichtige Funktion übernehmen. Räume übernehmen auch auf der Ebene der Erzählung eine Funktion und sind jenseits ihrer ästhetischen Erfahrbarkeit relevant. Zu Beginn von Leans Filmen findet der Zuschauer eine Art topografische Landkarte (topografische Räume) vor, die von unterschiedlichen Figuren mit jeweils unterschiedlichen Bedeutungen aufgeladen wird (semantische Räume). Was Leans Hauptfiguren mit bestimmten Räumen verbinden, widerspricht der herrschenden Norm ihres Umfeldes: Hier trifft Heimat auf Fremde, Himmel auf Hölle, Abenteuer auf Gefahrenpotenzial. An den Grenzen der Bedeutung von Räumen entstehen also inhaltliche Konflikte: Leans Hauptfiguren sind ‚anders‘, sehen ihre Welt ‚anders‘, entsprechen damit nicht der Norm und werden von ihrem Umfeld als Störfaktor wahrgenommen.

The Effect of Cooling Media on Tensile Strength of Medium Carbon Steel in Post Welding Process Using Electric Welding (SMAW) with E7018 Electrodes
Authors: Zulhafril Herman , Jasman Jasman , Tespoer Kimberly June
Published: February 2021

The use of cooling media in post welding process will affect the tensile strength of a material. This study aims to determine how much the influence of using cooling media in post welding and which cooling media is appropriate to use. The process is done by comparing the tensile strength of each cooling media, namely the cooling media of water, air, and coolant. The use of cooling media is carried out after the welding process, until the material that is ready to be welded reaches room temperature. Based on the experiments that have been conducted, the use of post-welding cooling media affects the tensile strength of medium carbon steel with the highest effect on the water cooling media, then the coolant media, and the lowest is the air cooling media. Therefore, the choice of the use of cooling media significantly affects the tensile strength of medium carbon steel in the post-welding process.
The Effect of Preheating and Non-Preheating in Cast Iron Welding Toward Mechanical Properties

Cast iron material is a material that has brittle properties and is less able to withstand stress due to the welding cycle caused by flake graphite in cast iron. Because of these problems, in connecting cast iron materials using the SMAW welding method, it is necessary to have heat treatment (preheating) to avoid the welding problems on the properties of cast iron. The purpose of this study is to determine the effect of heating and non-heating on the cast iron before the welding process. Therefore, this research will play a crucial contribution as a reference for cast iron welding researchers and cast iron welding process. The method of the research was experimental research, where the measurement results were obtained directly from the specimens. The welding was using an open V seam. The specimen used was cast iron with a thickness of 8 mm. One cast iron was given heat treatment at a temperature of 260ºC and the others did not receive heat treatment before being welded. The welding process used SMAW with CIN - 2 electrodes with a diameter of 3 mm. The test used the bending test on the face specimens according to the American Welding Society D1.1 standard. The results showed that there was an effect of the preheating treatment on cast iron, which that the non-preheating specimens were easier to fracture than the preheating specimens. Thus, it can be concluded that welding with preheating is better than welding without preheating.

This article discusses of acculturation between Islam and local culture in the Pakpak-Dairi community. The contact between the two cultural elements does not negate each other but is accommodative. This paper shows that Pakpak Dairiâ€™s current culture results from long acculturation between cultures, namely ancestral traditions, Hindu-Buddhist, and Christian. The research findings confirm that the politics of Islamic acculturation is reflected in various traditional ceremonies and other cultural expressions. Religious and traditional leaders play a role as agents in the acculturation process received of Islam. This process also contributes to the realization of social harmony in the Pakpak-Dairi community
Impact of wind and solar power plants on the reliability of the IPS

One of the most promising areas in the development of the electric power industry is generally regarded to lie in expanding the share of renewable energy sources (RES) in the electric energy balance of power systems in the form of wind and solar power plants (WPP and SPP), the saving of organic fuel (coal, gas, fuel oil) and the reduction of environmentally harmful emissions into the atmosphere considered to be their most important advantages. However, the impact of RES on the controllability of the modes of operation of electric power systems and on the reliability of the IPS operation remains quite unexplored.

Currently, the global energy industry uses 318 million kW of WPP and about 142.4 million kW of SPP, of which the major West European countries account for about 227 million kW, or 49.3%. On average, wind and solar power plants account for almost 30% of the total generating capacity in Western Europe, with Denmark having the largest share of WPP (47%) and Germany having the highest share of SPP (18.6%). However, an uncontrolled growth in the share of WPP and SPP in the structure of generating capacities of power systems begins to manifest itself in a sharp decline in the reliability of the power industry due to the fact that a number of negative properties of WPP and SPP have not been taken into account (at least, to a sufficient extent), which manifested themselves in practice in a system accident in the UK power system that occurred on August 09, 2019, when, as a result of an "ordinary" short circuit, a system accident occurred, with up to 1.1 million consumers with a total load of 1690 MW disconnected from the power supply system for a period of 15 to 45 minutes. This is estimated to have resulted in economic losses for consumers amounting to 12.3–15.0 million USD.

The reason for this is that the high sensitivity of WPP, SPP, CCGT and gas piston units to voltage and frequency drops is not properly considered in conditions of insufficient capacity of the rotating (mobile) generation reserve. Damage can be prevented by increasing the rotating reserve within the available reserve of the power system, which will require an increase in funds for maintaining the same due to additional fuel consumption. The ratio of reduction of probable damage to consumers and the cost of additional fuel consumption for maintenance of a required rotating reserve in the power system allows to economically substantiate the strategy and scale of introduction of renewable energy sources to the power industry.

The authors assess the impact of the communication process on comprehensive study of renewable energy sources (RES) and its actualization as a factor in the development of alternative energy in the Russian Federation.

The aspects of improving communications and involving their processes and tools (technologies, tools, formats) in the creation of alternative energy infrastructure in Russia with the aim of improving the natural landscape in the conditions of predominant development of hydrocarbon economy have been identified and presented.

The study shows the role and the importance of transmitting knowledge about the global limitations of natural forces and resources, high rate of changes in the natural and climatic conditions of living on the planet Earth for the investment of states with centralized power industry in alternative sources of electricity, their creation and integration with existing energy infrastructure based on hydrocarbon raw materials.

The mechanisms of a political, economic, energy-technological, socio-ecological and educational-informational nature are described, which, when combined, can act synergistically in the current unstable realities to change the situation dramatically for the better and to form hybrid, more balanced and safer fuel and energy solutions on our planet and in Russia in particular.

It is concluded that the communication process in the field of alternative energy, which reduces the negative destructive impact on the environment, can become a determining factor and a serious driver for the development of the renewable energy sector under certain circumstances that are highlighted as relevant in this study.

A brief and essential description of the sources of electric energy generation is given, water, sun and wind being the initial resources for their generation. In relation to each type of alternative generators, both standard and universal communication processes (means) can be used, as well as those adapted exclusively to a specific renewable resource.

Lipid metabolism and dietary choices directly affect the outcome of overall weight management in both lean and non-lean individuals. However, the perception of consuming spicy foods has diverse meaning among people. To understand this, it is essential to have thorough knowledge on how food preference is tied to health outcomes. The aim of this study is to enhance the understanding of how food preference affects the health outcome and perception in lean and non-lean populations. A mixed methods study was conducted via analysis of consumers’ food choices and compared the data based on age, gender, and body weight. The participants in audio recorded interviews were comprised of residents from a single town in a rural state. The study shows that most participants were aware of the implications that food choices had on their health status and it emphasizes the importance of understanding the differences between consumption of spicy and non-spicy foods. Spicy food consumption was associated with decreased overall portion size as well as increased satisfaction following the meal. Environmental factors, such as the influence of family and friends, impacted spicy food consumption according to most participants. The outcome of the study provides a comprehensive understanding of food preferences from a relatively large exploratory study. The observations made here show rudimentary associations between physical attributes and levels of food consumption. Future studies could further identify how certain attributes relate to food choices and levels of spicy food consumption in greater detail.
