Examining the Impact of Question Construction on Reporting of Sexual Identity: Survey Experiment Among Young Adults
Authors: Young William J , Bover Manderski Michelle T , Ganz Ollie , Delnevo Cristine D , Hrywna Mary
Published: August 2021

Background

Compared with heterosexuals, sexual minorities in the United States experience a higher incidence of negative physical and mental health outcomes. However, a variety of measurement challenges limit researchers’ ability to conduct meaningful survey research to understand these disparities. Despite the prevalence of additional identities, many national health surveys only offer respondents 3 substantive options for reporting their sexual identities (straight/heterosexual, gay or lesbian, and bisexual), which could lead to measurement error via misreporting and item nonresponse.

Objective

This study compared the traditional 3-option approach to measuring sexual identity with an expanded approach that offered respondents 5 additional options.

Methods

An online survey experiment conducted among New Jersey residents between March and June 2021 randomly assigned 1254 young adults (ages 18-21) to answer either the 3-response measure of sexual identity or the expanded item. Response distributions for each measure were compared as were the odds of item nonresponse.

Results

The expanded version of the question appeared to result in more accurate reporting among some subgroups and induced less item nonresponse; 12% (77/642) of respondents in the expanded version selected a response that was not available in the shorter version. Females answering the expanded item were less likely to identify as gay or lesbian (2.1% [10/467] vs. 6.6% [30/457]). Females and Non-Hispanic Whites were slightly more likely to skip the shorter version than the longer version (1.1% [5/457 for females and 3/264 for Non-Hispanic Whites] vs. 0% [0/467 for females and 0/277 for Non-Hispanic Whites]). About 5% (32/642) of respondents answering the longer item were unsure of their sexual identity (a similar option was not available in the shorter version). Compared with respondents answering the longer version of the question, those answering the shorter version had substantially greater odds of skipping the question altogether (odds ratio 9.57, 95% CI 1.21-75.74; P=.03).

Conclusions

Results favor the use of a longer, more detailed approach to measuring sexual identity in epidemiological research. Such a measure will likely allow researchers to produce more accurate estimates of health behaviors and outcomes among sexual minorities.

Authors: Koshechkin Konstantin , Lebedev Georgy , Radzievsky George , Seepold Ralf , Martinez Natividad Madrid
Published: August 2021

BACKGROUND

One of the most promising health care development areas is introducing telemedicine services and creating solutions based on blockchain technology. The study of systems combining both these domains indicates the ongoing expansion of digital technologies in this market segment.

OBJECTIVE

This paper aims to review the feasibility of blockchain technology for telemedicine.

METHODS

The authors identified relevant studies via systematic searches of databases including PubMed, Scopus, Web of Science, IEEE Xplore, and Google Scholar. The suitability of each for inclusion in this review was assessed independently. Owing to the lack of publications, available blockchain-based tokens were discovered via conventional web search engines (Google, Yahoo, and Yandex).

RESULTS

Of the 40 discovered projects, only 18 met the selection criteria. The 5 most prevalent features of the available solutions (N=18) were medical data access (14/18, 78%), medical service processing (14/18, 78%), diagnostic support (10/18, 56%), payment transactions (10/18, 56%), and fundraising for telemedical instrument development (5/18, 28%).

CONCLUSIONS

These different features (eg, medical data access, medical service processing, epidemiology reporting, diagnostic support, and treatment support) allow us to discuss the possibilities for integration of blockchain technology into telemedicine and health care on different levels. In this area, a wide range of tasks can be identified that could be accomplished based on digital technologies using blockchains.
Psychological Violence Against Arab Women in the Context of Social Media: Web-Based Questionnaire Study (Preprint)
Authors: Omar Bali Ahmed , Omer Emad , Abdulridha Kawa , Ahmad Araz Ramazan
Published: August 2021

BACKGROUND

Social media provides women with varying platforms to express themselves, show their talents, communicate and expand their social relationships, and break the shackles imposed by their societies. Theoretically, social media can play a significant role in developing women’s freedom and decreasing social pressures; nonetheless, women continue to face violence during the social media era mainly in the form of psychological violence.

OBJECTIVE

This study aims to conduct an empirical in-depth analysis of how the digital space, particularly social media, provides men with new opportunities to surveil, restrict, harass, and intimidate feminists in Arab countries.

METHODS

This study includes an empirical survey to investigate what Arab women think are the causes and types of violence wielded against them and their perspectives on the impact of that violence. This study used a web-based questionnaire administered through Google Forms (n=1312) with responses from Arab women aged 15 years and above from all Arab countries.

RESULTS

We found that most Arab women feared posting an actual photograph of themselves on their social media accounts and only approximately one-third (490/1312, 37.3%) did so. Most women indicated that they encountered sexual harassment regardless of their age. Furthermore, most women were not aware of the legal aspects of this crime and even those who were aware indicated that they would not press charges for several reasons, including bringing dishonor upon their families, the time-consuming nature of litigation, and fear of revenge.

CONCLUSIONS

This study shows that young and less educated women are more vulnerable to abuse from either social media users or being condemned by their families. This has several effects, including lower self-esteem and hesitancy in seeking a job, feelings of mistrust and fear, cynicism, anxiety, depression, and sleep disorders. These issues hold women back from using social media in positive ways and some consider leaving social media.
Language of Grief and Body in Translation
Authors: Gil-Montero Michelle
Published: August 2021

Argentina’s 1976-1983 military dictatorship was, in the words of scholar Marguerite Feitlowitz, "an intensely verbal takeover" (Feitlowitz 22). The language of the military junta was one that spun an illusion of reality out of abstractions and absolutes, while in fact, it cloaked real events to produce a culture of denial. I discuss my translation of María Negroni’s lyric novel about The Dirty War, The Annunciation, which enters the dysfunctional language of dictatorship as a site of poetic play. Negroni dramatizes how this language prohibits, above all else, grief. Specifically, it deploys a language of melancholy as a radical gesture in a linguistic-political context where the body, and the embodied, have disappeared. Drawing from passages in my translation I highlight translation as it participates in problems of loss, silence, and absence, and ultimately, as it performs the recuperative work of mourning.

Authors: Kamruzzaman Mohammed
Published: August 2021

Fraud detection in meat is a challenging task for researchers, consumers, industries, and regulatory agencies. Traditional approaches for fraud detection are time-consuming, complicated, laborious, and expensive; they require technical skills. Therefore, much effort has been devoted in academia and industry to developing rapid and nondestructive optical techniques for fraud detection in meat. Among them, hyperspectral imaging has gained enormous attention and curiosity throughout the world. Hyperspectral imaging is an emerging analytical technique that combines spectroscopy and imaging in one system to acquire spectra and spatial information from an object simultaneously. Hyperspectral imaging is the only analytical technology that answers commonly asked analytical questions such as what chemical species are in the samples, how much, and most importantly, where they are located. Therefore, the technology will undoubtedly play indispensable roles in research and industry for fraud detection in the coming days.

Authors: Melekhin Andrey A.
Published: August 2021

Introduction. The problem relevance is explained by the advancement of digital technologies in science and engineering, including the design and reconstruction of engineering systems of buildings and structures. Numerous regulatory documents have been developed so far, including codes of rules, All-Russian State Standards (GOSTs) and other regulatory instruments. This scope of documents is regularly updated. The problem is the insufficient adaptation of this regulatory documentation in software packages. Materials and methods. To solve this problem and to complete a feasibility study backing the choice of envelopes and the analysis of thermal loads on buildings, an engineering calculator has been developed. The author has designed calculation algorithms for an engineering calculator based on (1) the regulatory documentation, applicable to the thermal protection of buildings, and (2) the heat flow analysis methodology based on the aggregate parameters of a construction facility, and (3) the economic justification of the methodology application. Results. The results obtained using the engineering calculator and based on the heat flow analysis algorithm that employs aggregate parameters are compared with the results extracted from the building designs. To solve the applied problem, the engineering calculator uses one sample building to analyze the feasibility of application of various types of envelopes. Conclusions. In the course of research, the author set and solved the following tasks: the method of specific heat flow analysis, based on the aggregate parameters of a construction facility, was applied to calculate new a, n coefficients; DHTML software was applied to develop algorithms for engineering calculators, including the heat flow analysis algorithm based on the aggregate parameters and the feasibility study algorithm applied to justify the use of particular types of building envelopes; a web application was developed to analyze the heat flow on the basis of the aggregate parameters and the feasibility of application of certain types of building envelopes.

Published: August 2021

Glazing is one of the dominant features of modern and contemporary architecture. This envelope design may have a great impact on operational energy demand of buildings. In this work, glazed façade systems available in Argentina are analyzed, with the purpose of determining the associated thermal transmittance ranges, in terms of the profiles’ design, the type of glazing and the size of glass panes. First, by using bidimensional numerical calculation, the impact of several profile design parameters on thermal transmittance is studied, highlighting the relevance of glazing fixing methods, to then calculate the thermal transmittance of the entire facade. The results indicate that the thermal transmittance value of glazed facades, mainly depends on the transmittance of the glass used, and exceeds this by 24% on average.

Authors:   Universidad de San Buenaventura, Cali, Colombia, Cobo-Fray Constanza , Montoya-Flórez Olga Lucia
Published: August 2021

This work presents the results of research made within the framework of the Solar Decathlon LAC 2019 international competition, which aimed at designing and building a prototype of a TUHOUSE (Technically Unique House Using Solar Energy) affordable dwelling, at a 1:1 scale, a house that is capable of incorporating sustainable and bioclimatic strategies for the tropical region. The methodology consisted of a design workshop with interdisciplinary work from the different architecture and engineering areas in programs at the Universities of San Buenaventura and Autonoma de Occidente (Cali, Colombia). The main contribution of the methodology was to achieve interdisciplinary work from the initial stages, alongside students and teachers participating in the construction of the prototype, before finally checking its performance using the contest’s tests. Among the results that stand out from of this experience, are an urban proposal with high habitability and density, the testing of passive design strategies focused on a prototype envelope that can be replicated in similar conditions, but also the importance of the question about the validity of the thermal comfort model proposed for tropical regions.
La vivienda colectiva de la modernidad en tiempos de COVID19 aportaciones del paradigma habitacional
Authors:   Universidad Nacional Autónoma de México, Ciudad de México, México, Gómez-Porter Pablo Francisco
Published: August 2021

Modern collective housing generated an urban-architectural design paradigm, which incorporated spaces whose design promoted, following modern architects, health and hygiene through the circulation of clean air, natural lighting and ventilation inside dwellings, as well as in the shared spaces and those where people move around, characteristic of this housing typology. These design elements seem to be useful to reduce the spread of the SarsCov2 virus, that is currently affecting the entire world. Field and online work was carried out with the inhabitants of the CUPA, a housing complex representative of modern architecture in Mexico City, to verify this assumption. Using volumetric reconstructions and online questionnaires, the design elements that embody modern ideals, aimed at ensuring healthy indoor and outdoor spaces, were analysed. The usefulness of the collective facilities, public spaces and the design of the four housing typologies found within the, were assessed. The results of the study and the absence of COVID-19 cases in CUPA help to prove the validity that modern architecture has regained during the global pandemic, as well as the importance of the lessons from the past to integrate new design paradigms for a post-Covid architecture.

The post-pandemic crisis of contemporary housing, triggered by COVID-19, only but extends, to the entire world, many of the questions in which, permanently, housing is immersed within, in an ongoing crisis of developing countries. How to make houses more shareable, flexible, transformable, productive, participatory, livable, etc.? In that sense, by studying low-income housing in these countries, it is possible to analyze alternatives to the current dwellings, that arise from informality as a response to those questions shared worldwide today. This article describes part of a research carried out at Universidad Católica de Santiago de Guayaquil, which analyzes the physical and social transformations in consolidated informal dwellings within the city center. The techniques used, include planimetric surveys of case studies, interviews to users, and mapping out the use of the dwellings throughout the day. The analysis focuses on the interaction exerted between several nuclear families inside the dwelling and their objects. Thus describing a habitat transformational and production system linked to objects, where the dwelling is understood as a social system of objects and people, in continuous interaction and transformation.

Authors: Fernández Suárez Belén , López Gonsálvez Tatiana , Soto González Adrián , Egea Padilla Miguel
Published: August 2021

Este artículo pretende analizar el fenómeno de la nueva emigración española en París (Francia) surgida en la etapa de crisis económica (2008-2014) como una comunidad virtual a través de los grupos de Españoles en París de Facebook. Este proceso de movilidad intraeuropea permite articular una red de apoyos, información y socialización en destino a través de la creación de estas comunidades imaginadas en las redes sociales. Los grupos de Españoles en París constituyen a través de lazos débiles una comunidad virtual, un tejido asociativo difuso, que con mayor o menor asiduidad agrupa colectivamente a este colectivo migratorio. La dinámica de interacción de estos grupos nos permitió descubrir cómo sus funciones son ambiguas, pues desarrollan tanto mecanismos de solidaridad comunitaria, como a su vez ponen en marcha dinámicas de exclusión de esta ciudadanía virtual. La metodología utilizada fue una etnografía virtual realizando una  observación de los perfiles de Facebook (Españoles en París).

Thrombolysis in May-Thurner Syndrome and Iliofemoral DVT
Authors: Patel Matthew , Singh Kevin , Mazzetti Adam , Kaplovitch Eric
Published: August 2021

Post-thrombotic syndrome (PTS) describes residual leg swelling, pain, and venous insufficiency that persists after acute deep vein thrombosis (DVT). PTS occurs in 40 to 60% of patients and contributes significantly to patient morbidity and healthcare costs. Despite standard therapy including anticoagulation, early ambulation, and compression stockings. PTS is more common in iliofemoral DVT. Despite conflicting evidence, there has been increasing use of endovascular therapies such as thrombolysis, thrombectomy, and venous stenting to reduce the incidence of PTS. May-Thurner Syndrome (MTS) is a significant risk factor for the development of iliofemoral DVT and PTS because of the compression of the left common iliac vein by the overlying right common iliac artery. The main objective is to review the evidence for endovascular management of iliofemoral DVT using MTS as an illustration of a patient population that may benefit from this therapy. Currently, endovascular therapies are not the recommended routine management of nongangrenous iliofemoral DVT. But can be considered in exceptional cases, such as MTS or other compressive syndromes, for obtaining venous patency and potentially prevent severe PTS.ResumeLe syndrome postphlébitique (SPP) correspond à un œdème résiduel des jambes, à de la douleur et à une insuffisance veineuse qui persiste après une thrombose veineuse profonde (TVP) aiguë. Il survient chez de 40 à 60 % des patients et contribue grandement à la morbidité du patient et aux coûts en soins de santé, malgré les traitements classiques comprenant l’anticoagulothérapie, l’ambulation précoce et les bas de contention. Le SPP est plus fréquent dans les cas de TVP iliofémorales. Malgré des données probantes contradictoires, on utilise de plus en plus les traitements endovasculaires comme la thrombolyse, la thrombectomie et la mise en place d’endoprothèses veineuses pour réduire la fréquence du SPP. Le syndrome de May-Thurner (SMT) est un facteur de risque important de l’apparition d’une TVP iliofémorale et du SPP en raison de la compression de la veine iliaque commune gauche par l’artère iliaque commune droite contre le plan vertébral. Le principal objectif consiste à examiner les données probantes relatives à la prise en charge endovasculaire de la TVP iliofémorale en utilisant le SMT pour illustrer une population de patients qui pourrait bénéficier de ce traitement. À l’heure actuelle, on ne recommande pas les traitements endovasculaires dans la prise en charge courante de la TVP iliofémorale non gangréneuse, mais dans des cas exceptionnels, comme le SMT ou autres syndromes de compression, ils peuvent être envisagés pour obtenir une perméabilité veineuse et prévenir les cas graves de SPP.

Bu çalışmanın amacı Karadeniz’in Şile kıyılarında yaşayan Mesogobius batrachocephalus türünün vücudunun farklı bölgelerinde bulunan pullarının morfolojik ve morfometrik özelliklerinin cinsiyete bağlı değişimlerini tespit etmektir. Bu çalışma kapsamında, toplam 32 birey (n♀= 16, n♂=16) değerlendirilmiştir. Bireylerin minimum ve maksimum total boy ve ağırlıkları sırasıyla 17,6 - 27,7 cm ve 46,6 - 231,0 g aralığındadır. Farklı vücut bölgelerindeki pullar dişi ve erkek bireyler için ayrı ayrı değerlendirilmiştir. Pul boyutu ve pul şekli gibi morfolojik özellikler hem dişi-erkek bireyler hem de incelenen vücut bölgeleri arasında ayırt edici karakterler olarak belirlenmiştir. Diğer morfolojik özellikler (pul merkezinin pozisyonu, sirkuli, radii tipi, pulun rostral ve kaudal kenarı) ise hem dişi-erkek bireylerde hem de belirlenen bölgeler arasında benzer özellikler göstermektedir. M. batrachocephalus bireylerinin vücut bölgelerindeki pullar karşılaştırıldığında, dişi ve erkek bireylerdeki pulların morfometrik değerleri (genişlik, alan ve çevre) arasında 1. bölge, 4. bölge ve 5. bölge için istatistiksel olarak anlamlı farklılıklar tespit edilmiştir (P<0,05). Bu çalışmada, M. batrachocephalus türünün pul morfolojisi ve morfometrisine ait bilgiler ilk defa sunulmuştur. Çalışma sonucunda dişi ve erkek bireylerin bu özellikler bakımından farklılık gösterdiği tespit edilmiştir. Bu sebeple filogenetik çalışmalarda önemli yer tutan pul morfolojisi ve morfometrisinin, M. batrachocephalus türünün hem dişi hem de erkek bireylerinde ayrı ayrı değerlendirilmesinin gerektiği önerilmektedir.
Evaluation of the Water Quality of Karabal Stream (Gediz River, Turkey) and Comparative Performance of the Used Indices
Authors: Ertaş Alperen , Yaşartürk Merve , Boz Tuğba , Tüney Kızılkaya İnci
Published: August 2021

We used seven biotic indices to determine the water quality of Karabal Stream (Gediz River) in West Anatolia, Turkey. The indices were based on benthic macroinvertebrate and physicochemical parameters: Saprobi Index (SI), Biological Monitoring Working Party (BMWP), Average Score per Taxon (ASPT), Family Biotic Index (FBI), Belgian Biotic Index (BBI), EPT-Taxa [%] were used as biotic indices and Shannon-Weaver index (SWDI), Simpsons index (SDI) and Margalef index (MDI) for diversity. Ten taxonomic groups were found in Karabal Stream consisting of Crustacea, Oligochaeta, Gastrapoda, Ephemeroptera, Plecoptera, Trichoptera, Odonata, Coleoptera, Diptera, and Hemiptera. The water quality along the stream varied from good class in the upstream stations, to moderate in downstream stations according to the most suitable indices. According to canonic correspondence analysis (CCA), the distributions of Diptera, Oligochaeta, and Hemiptera species are positively correlated to EC, Cl, Turbidity, Temperature, NH4-N, NO2-N, and NO3-N while they are negatively correlated to DO, DOS and pH. The distributions of EPT species are positively correlated to DO, DOS and pH. According to Pearson’s correlation, the BBI, BMWP (Original), BMWP (Spanish), and EPT-Taxa [%] metrics were sufficient in the estimation of water quality in the examined watercourse. Considering studies in surface waters of Turkey, the BMWP and EPT-Taxa [%] indices reflect the water quality as correctly in all studies we examined, however, BBI did not always show reliable results. Therefore there is a need for the establishment of a Turkish Biotic Index which takes into account country-specific macroinvertebrates, their abundance, biology, and ecology.
Socio-cultural Change and Conflict in the Coastal and Small Island Community in Indonesia
Authors: A Kinseng Rilus
Published: August 2021

Social change and conflict are an integral part of any society, including coastal and small island communities in Indonesia. Therefore, doing research on social change and conflict in these communities is very important. As a tribute to the late Prof. Tjondronegoro, this study analyzes briefly the role of Prof. Tjondronegoro in the study of social change in rural Indonesia. This study also analyzes socio-cultural changes, especially identity and sources of the changes, and social conflict in the coastal and small island communities. This is a qualitative study, conducted by examining relevant literatures. The study shows that the late Prof. Tjondronegoro was a lecturer on social change at graduate programme of IPB who had conducted researches regarding social change. Furthermore, the study indicates that socio-cultural changes have taken place in the coastal and small island communities due to changes of fishing technology, value system, tourism, mining activities, and government policies. Meanwhile, social conflicts have also taken place, mainly those related to access to livelihood sources. Thus, it can be concluded that the late Prof. Tjondronegoro played an important role in the development of research on socio-cultural change in rural Indonesia. Moreover, the coastal and small island communities in Indonesia have undergone social changes and conflict.
Quantitative Assessment of Right Ventricular Size and Function with Multiple Parameters from Artificial Intelligence-Based Three-Dimensional Echocardiography: A Comparative Study with Cardiac Magnetic Resonance
Authors: Zhu Ying , bao Yuwei , Zheng Kangchao , Zhou Wei , Jun Zhang , Sun Ruiying , Deng You-Bin , Xia Liming , Liu Yani
Published: August 2021

Abstract Aims: This study aimed to explore the validation and the
diagnostic value of multiple right ventricle (RV) volumes and functional
parameters parameters derived from a novel artificial intelligence
(AI)-based three-dimensional echocardiography (3DE) algorithm compared
to cardiac magnetic resonance (CMR). Methods and Results: 51 patients
with a broad spectrum of clinical diagnoses were finally included in
this study. AI-based RV 3DE was performed in a single-beat HeartModel
mode within 24 hours after CMR. Whether in the entire population or the
patients with moderate and poor image quality, RV volumes and right
ventricular ejection fraction (RVEF) measured by AI-based 3DE showed a
statistically significant correlation with the corresponding CMR
analysis (P<0.05 for all). The Bland-Altman plots indicated
that these parameters were slightly underestimated by AI-based 3DE.
Based on CMR derived RVEF<45% as RV dysfunction, end-systolic
volume (ESV), end-systolic volume index (EDVi), stroke volume (SV), and
RVEF showed great diagnostic performance in identifying RV dysfunction,
as well as some non-volumetric parameters, including tricuspid annular
systolic excursion (TAPSE), fractional area change (FAC), RV septum and
free-wall longitudinal strains (LS) (P<0.05 for all). The
cutoff value was 43% for RVEF with a sensitivity of 94% and
specificity of 67%. Conclusion: AI-based 3DE provide rapid and accurate
quantitation of the RV volumes and function with multiple parameters.
Both volumetric and non-volumetric measurements derived from AI-based
3DE contributed to the identification of the RV dysfunction, even in the
patients without excellent image quality of RV 3DE. Keywords: artificial

The first hundred days of the Biden administration and the us foreign and security policy
Authors: Simic Dragan , Zivojinovic Dragan
Published: August 2021

The paper deals with the foreign and security policy of the United States of
America during the first hundred days of the Biden administration. Ever
since Franklin Delano Roosevelt?s first term, the presidential performance
at the beginning of the administration has been measured by the first
hundred days of a president?s term. The most important intentions about what
is to be achieved, the selection of the team, key appointments, and the
establishment of the National Security Council System, the most important
speeches, and concrete moves towards regional and functional issues, say a
lot about what the foreign and security policy of an administration will
look like. President Joe Biden is no exception. Moreover, his insistence
that the circumstances in which the United States finds itself are a truly
?Rooseveltian moment? contributed to the first hundred days of his
administration being monitored with special attention. The authors start
from the hypothesis that Biden, owing to his experience in government and a
good reading of the circumstances in which America and the world find
themselves, established a good and functional national security system as
well as a clear list of foreign policy priorities. He, like Franklin Delano
Roosevelt, found the appropriate balance between values and interests, means
and goals, pragmatism and principle. The authors conclude that, although the
first steps are promising, it remains to be seen whether Biden will reach
the highest standards set by his famous predecessor, especially in the face
of some unforeseen and unexpected events.
Problems and challenges of internet governance at the international level
Authors: Vuletic Dejan , Djordjevic Branislav
Published: August 2021

The activities of the United Nations, as the most important international
organization, as well as the efforts of certain regional and national
organizations, are discussed in this article on the subject of Internet
governance. The article pays special attention to the ?internet of things,?
the increasing use of which causes the emergence of new, dangerous, and
serious threats, further complicating the problem of Internet governance.
The stated subject of the research is directly related to the aim of the
paper, which is to present and analyse the activities of various entities,
international, regional and national institutions and organizations, as well
as leading states, primarily the United States and Russia, and documents
that attempt to regulate activities in cyberspace. The basic hypothesis is
that opposing national interests prevent international bodies, particularly
the United Nations, from reaching a consensus on the fundamental principles
of Internet governance, resulting in insecurity in the face of increasingly
frequent, diverse, and serious threats to the Internet and cyberspace in
general. Based on the arguments presented in the paper, there have been
numerous attempts to regulate Internet governance that have not materialized
in concrete decisions implemented in national legislation and practice. Due
to the growing dependence on information and communication technologies, the
problem of the non-existence of regulations in this area makes the
information society even more vulnerable.

Authors: Vukovic Nebojsa
Published: August 2021

The paper conducts research on the understanding of war in Russian military
thought from 2013 to 2019, during which time General of the Army Valery
Gerasimov was (and still is) the Chief of the General Staff of the Armed
Forces of the Russian Federation. Also, the subject matter of the research
study is his personal stimulus to the intensification of the studies of the
nature, character, physiognomy and types of contemporary war in the Russian
military-scientific community, as well as the theoretical results obtained
by Russian authors in that particular field in recent years. Essentially,
the research effort made by the author of this paper focuses on the analysis
of the formulations used by Russian authors to explain/define the content
and scope of the term ?war?, as well as the interpretation of the typology
of wars devised by some of them. A special reference has been made regarding
the understanding of the so-called hybrid war in contemporary Russian
military thought. For the purpose of the analysis, studies/monographs or
scientific papers published in eminent Russian military scientific or
professional journals by the relevant authors (most frequently retired
military personnel, primarily those with the rank of colonel or general)
from the Armed Forces of the Russian Federation were chosen. The research
results presented in this paper can be useful to domestic political science,
i.e., to the system of military sciences, in the sense of enriching the
types of knowledge with respect to the comprehension of war and the
potential commencement of the fundamental (according to their essence,
partly philosophical) research studies dealing with that topic.
Armed forces modernisation and shifts in the perception of the Chinese threat
Authors: Pejic Igor
Published: August 2021

Following the principles of realist school of international relations we are
analysing the shifts in Chinese military budget, military posture and
overall modernization of armed forces before and after the American ?Pivot?
to Asia. These results are later compared to the United States? foreign
policy and military posture in East Asia that had changed in the past
decade. Employing Walt?s theory of balance of threat in the following
article we have analyzed the shifts in Chinese military power and how other
regional actors? perceptions had changed during the last two decades of the
21st century. China that began internal balancing at the end of the
twentieth century wasnot perceived as a threat to American interests in East
Asia, which could potentially alter the regional status quo. The United
States along other regional countries didnot perceive Chinese growing
military power that was primarily land based, as a factor that should be
contained. However, things started to change as Beijing assertiveness in
South China Sea alerted other regional actors of Chinese growing naval power
and political aspirations. As the research results show, the idea that any
kind of balancing can lead to revisionism in the unipolar system is only
partially correct concept which can be affected by intensity and nature of
balancing politics.

Authors: Kovco-Vukadin Irma , Skarica Dora
Published: August 2021

The coronavirus pandemic pose tremendous challenge for all countries of the
world. People who experience domestic violence deserve special attention in
such social circumstances. The purpose of this paper is to present research
on students? attitudes about domestic violence in pandemic conditions. In a
sample of 334 students from Croatia we analyzed their acceptance of myths
about domestic violence, attitudes about domestic violence in pandemic
conditions, and the correlation between the acceptance of myths and
attitudes about domestic violence. The results indicate the following:
students accept myths about domestic violence at the lesser level, they
believe that measures to combat coronavirus have led to an increase in all
analyzed forms of domestic violence, they do not think that the policingin
those cases is well or that victims receive sufficient help and support in
pandemics. Differences in students? attitudes towards gender and knowledge
of the victim were found, as well as the correlation between attitudes and
basic political orientation. The correlations between students? attitudes
and acceptance of myths about domestic violence were also established.
Support to victims and witnesses in the Republic of Croatia during the COVID-19 pandemic
Authors: Hamer Vidmar
Published: August 2021

The purpose of this article is to analyze how the COVID-19 pandemic affected
the work of the Victim and Witness Support System in the Republic of
Croatia, particularly Service for Victim and Witness Support at the Ministry
of Justice and Public Administration of the Republic of Croatia, Victim and
Witness Support Departments at the County Courts, Network of Support and
Cooperation for Victims and Witnesses of Criminal Offences (consisting of 10
organizations operating in 13 counties) and National Call Center for Victims
of Crime 116 006. The problems faced by support organizations and services
as well as victims are presented in the paper. Certain changes in the
procedures and new forms of cooperation have been noticed, which improved
the support system and enabled victims' easier access to their rights. In
order to build a resilient society and organizations, as well as to prevent
burnout of professionals and ensure their resilience, it is important to
cooperate with each other and provide support to helpers in the form of
training, regular meetings, consultations and supervision.
ST PETERSBURG PARENTS’ CIRCLE ON THE CRISIS OF FAMILY EDUCATION IN THE LATE 19TH AND EARLY 20TH CENTURIES AND WAYS TO OVERCOME IT
Authors: ANISIMOVA LARISA IU.
Published: August 2021

This article considers the theoretical and practical activities of the socio-pedagogical organization St Petersburg Parents' Circle, which arose at the Pedagogical Museum of Military Educational Institutions and since 1906 has become an independent organization that brought together outstanding teachers, doctors and parents interested in the early development of the child and family education. The members of the Parents’ Circle were convinced that family education was in crisis and sought to disseminate correct ideas about parenting to the general public. The practices of the public pedagogical organization have not yet been sufficiently studied by both domestic and foreign researchers.
A Novel and Efficient INC Based MPPT for PV System
Authors: Kumar Santosh , Wadhwani A. K. , Mishra Bharat
Published: August 2021

This paper discuss the Incremental Conduction based MPPT for tracking the solar power. Due to increment of power demand here to find the new type of generation system. The concept of Renewable Energy Source (RES) is now become a most popular for generation of power. There are basically three types of RES is used for generation process, Wind, PV, fuel cell. Solar system is one of the best RES technique for generation of electrical power but it have some drawback. It is only used in the daytime and has low efficiency. For improving the efficiency of the system here maximum power tracking is needed. Here Incremental Conduction based MPPT for tracking the solar power is used. The whole model is simulated in MATLAB /SIMULINK for checking the performance of the system and is applicable to different type of domestic loads. The THD of the system is calculated.
Thermal Analysis of IC Engine
Authors: Kumar Sourabh , Soni Mr. Rajesh
Published: August 2021

Calculating the heat transfer rate of the engine is very difficult due to the complex geometry design of the engine and the periodic flow of air and fuel during engine operation for full cycles. Various theories hypothesize that about 25% of the energy contained in the fuel is converted into useful work and the remaining 75% is released into the environment by the engine. The main objective of the present work is to improve the heat transfer rate of existing constructions of the engine cylinder block by modifying its construction and also with new materials. To this end, two CAD models were created using CATIA software, then a transient thermal analysis with ANSYS at ambient temperature for the summer season of 45oC for the real one and the proposed internal combustion engine design was performed one after the other. Other to optimize the geometric parameters and improve the heat transfer rate. From the results of the transient thermal analysis, it was found that the proposed engine cylinder block design has better performance and heat transfer rates than the actual engine cylinder block design.

Distributed generators using environmentally friendly energy sources such as wind, small water and solar energy have become an important part of the future smart grid/micro grid concept. Design of an autonomous photovoltaic system to study the reaction of solar modules to variable irradiation conditions and their effect on loads. The autonomous system must include a battery storage system to handle non-linear load responses on the AC side. And improve the output power of the photovoltaic system using the MPPT algorithm specially designed to drive linear and non-linear loads on stand-alone systems. And causing the system to respond to varying levels of radiation in the environment and achieve an uninterrupted regulated output of the system. The system examined the behavior of linear and non-linear loads with constant irradiation of 1000 wb / m2 and then modified it to a value between 1000 wb / m2 and 200 wb/m2. The harmonic content in the line voltage increased to 3.34% with a non-linear load by 0.54% with a linear load.
Stories of Indigenous sexual health: Promoting community wellness through sexual health education
Authors:   , Donaldson Richel
Published: August 2021

Indigenous communities and peoples have experienced erosion of their sexual wellness since contact with European peoples. Effective sexual health education is a human right shown to be an important part of overall health and wellness. Little research has been done on how to develop and implement sexual health education for Indigenous populations. This study utilizes an environmental scan to gain a comprehensive understanding of programming available for Indigenous peoples in BC, coupled with conversational style interviews with community storytellers to highlight effective practices. The findings of this research demonstrated that programs focused on promoting healthy sexuality generally or preventing HIV/AIDS and STBBI transmission while promoting safety and access to culture, utilized peer led approaches, and focused primarily on delivering services to youth. Storytellers demonstrated a strong passion for building relationships with participants and communities through engaging, accessible, and relevant sexual health education.
