Digital Currencies: Opportunities in Islamic Finance
Authors: Glavina Sofia Grigorevna , Asmiatullin Ravil Ramilevich
Published: July 2023

The article states that decentralization is one of the trends in the modern global finance market. The growth and active development of the Islamic finance and banking industry, the growth in the number of Muslims in the world and other factors determine the interest of researchers in digitalization issues. This paper is devoted to the study of the possibilities, approaches and views on the use of digital currencies from the point of view of Islamic finance. Methods of analysis and synthesis, comparative analysis is used. The approaches of various countries of the Muslim world to the introduction of digital currencies are analyzed, ongoing projects are considered. In the Islamic world, there has not yet been a consensus on the permissibility and scope of the possible use of digital currencies. The authors conclude that, in general, digital currencies can be harmoniously used within the concept of Islamic finance. This is facilitated by such factors as the transparency of decentralized finance and digital currencies, the contribution to the protection of the wealth of society, the focus on social benefits, which is in line with the good goals of Islamic finance and its social value.

Background:

Indazoles are known for their anti-cancer properties.

Objective:

The current investigation was on the synthesis and evaluation of novel indazole derivatives for their anticancer
properties.

Methods:

A series of novel indazoles were synthesized and characterized by IR, NMR and LCMS. We performed cytotoxic
studies for all synthesized compounds on different cell lines such as HeLa, MCF-7 and EAC using MTT assay.
The lead compound was tested further for its anti-tumor and anti-angiogenic effect on EAT tumor model.

Results:

Amongst the series of compounds synthesized, compound KA8 showed potent antiproliferative effect against
Hela, MCF-7 and EAC cell lines with IC50 values 10.4 to 11.5 and 13.5μM respectively. In addition, our compound
KA8 significantly decreased the cell viability, body weight, ascites volume and it also showed superior survival ability
of mice compared to control groups. Furthermore, it suppressed the formation of neovasculature in the peritoneum of
EAT-bearing mice.

Conclusion:

The findings reveal that the lead compound KA8 possesses potent anti-tumor and anti-angiogenic properties
thereby promising it to be developed as a novel anticancer agent with further mechanistic studies.
Social Media Interventions for Nutrition Education Among Adolescents: Scoping Review
Authors: Kulandaivelu Yalinie , Hamilton Jill , Banerjee Ananya , Gruzd Anatoliy , Patel Barkha , Stinson Jennifer
Published: July 2023

Background

Adolescence is a critical period for reinforcing healthy dietary behaviors and supporting the development of cooking skills. Social media may be an avenue for supporting these behaviors, as it is popular among adolescents and can improve access to nutrition education interventions. This study sought to understand the optimal implementation of effective social media–based nutrition education interventions to inform the implementation of future social media–based nutrition education interventions.

Objective

A scoping review of the characteristics, feasibility, effectiveness, and factors influencing social media–based nutrition education interventions for adolescents was conducted.

Methods

We searched MEDLINE, Embase, CINAHL, Web of Science, and PsycINFO databases using a predefined search strategy. Primary research articles were independently screened and included if they involved adolescent populations (10-18 years old) and delivered nutrition education through social media. The information on intervention characteristics, feasibility, effectiveness, and factors influencing social media–based nutrition education interventions was extracted.

Results

A total of 28 publications out of 20,557 met the eligibility criteria. Twenty-five nutrition interventions were examined by 28 studies. Fourteen interventions used homegrown social media platforms, 8 used Facebook, and 2 used Instagram. Feasibility outcomes were infrequently reported, and the cost of intervention delivery was not reported. Engagement with interventions was variable; high engagement was not required to elicit significant improvements in dietary behaviors. Tailoring interventions, offering practical content, meaningful peer support, and involving families and communities facilitated successful interventions. Strategies to address engagement and technical issues were varied.

Conclusions

Emerging evidence demonstrates that social media interventions for adolescent nutrition are acceptable and improve nutrition outcomes. Future interventions should strengthen peer support components and tailor delivery to specific populations. Further research should examine engagement, adherence, and the impact of interventions on behavioral and physical outcomes. This review is the first to examine the use of social media as the primary medium for nutrition education for adolescent populations. The analysis used in this review argues the importance of peer support in social media–based nutrition interventions and the need for user-centered design of the interventions.
MULTIMODAL ADAPTATIONS OF BAŠ-ČELIK: FROM A FAIRY TALE TO A COMIC AND ILLUSTRATED BOOK
Authors: Tasić Miloš , Stamenković Dušan
Published: July 2023

Employing the theoretical framework that represents a unique amalgam of the domains of multimodality, intermediality, transmedia storytelling and adaptation, the paper analyses the process of medial transposition of the folk fairy tale Baš-Čelik, primarily into Đorđe Lobačev’s comic book of the same name (1939/1989), and then into Petar Meseldžija’s 2008 illustrated book The Legend of Baš-Čelik (orig. Legenda o Baš-Čeliku). The paper presents verbal and graphic tools used by these authors in adapting the original text from a monomodal into multimodal media, with a special focus on three research directions. The first is the manner in which the compositional structure of the fairy tale is transferred into the comic and the illustrated book, with the aim of assessing the level of fidelity in these adaptations. The second direction is related to the most important narrative and stylistic differences (e.g., language and tone of narration). The third direction deals with the use of certain comics-specific techniques and resources, such as page layout, use of colour for emphasis, representation of speed and motion, and the presence or absence of particular graphic devices (upfixes and pictorial runes). Finally, the adaptations themselves are compared to each other, highlighting the major similarities and differences between them.
Tetrazolium test to estimate the physiological quality of tamarind (Tamarindus indica L.) seeds
Authors: Hernández Jenry Rafael , Iguaran-Diaz Camilo José , Araméndiz-Tatis Hermes , Cardona-Ayala Carlos Enrique , Espitia-Camacho Miguel Mariano
Published: July 2023

Tamarind (Tamarindus indica) is a fruit tree of African origin cultivated in more than 50 countries, including Colombia, mainly in the Colombian Caribbean departments, where its harvest generates significant income in rural communities. Its establishment presents a difficulty because the sexual seed presents physical dormancy and poor germination. The objective of this study was to evaluate Tamarind seed viability by using the tetrazolium test and to reduce the time needed for the determination of its physiological quality. Ripe and healthy fruits were collected from patio trees, from which their seeds were extracted, disinfected with 1% sodium hypochlorite, and washed with plenty of water before use. Subsequently, they were scarified with No. 100 sandpaper by the edges, except in the area of the micropyle. The completely random design was used in a 3x3 bifactorial arrangement, with four repetitions. The first factor, tetrazolium concentration (%), was tested at levels of 0.50, 0.75 and 1.00%, and the second factor, immersion time, at 2, 4, and 6 hours. The analysis of variance did not show significance for the tetrazolium concentration, while it did for the immersion time (p≤0.01), and the tetrazolium-time interaction (p≤0.05). Therefore, the concentration of 0.50% tetrazolium for six hours of immersion is a reliable alternative to determine the physiological quality of tamarind seeds compared to conventional germination testing due to its low cost and execution time. Likewise, the percentages of germination and germination speed index were higher when the seed was scarified with sandpaper than the conventional method.
Deciphering the Ages of Saline Water in the Baltic Sea by Anthropogenic Radiotracers
Authors: Lin Mu , Qiao Jixin , Hou Xiaolin , She Jun , Murawski Jens
Published: July 2023

The slow water renewal endows the Baltic Sea a strong retention of
pollutants/nutrients. Constraining water age is a practical way to
depict the transport pathways/timescales for water masses and
accompanying soluble substances. Although the water ages in the Baltic
Sea have been resolved by 3D ocean models 20 year ago, the simulated
results have not been verified. In this work, we exploited two
anthropogenic radionuclides (129I and 236U) as an age marker to
constrain the ages of inflowing North Sea saline waters into the Baltic
Sea. Our results indicate that the Baltic Sea has a highly stratified
structure with distinctly different timescales for surface-water and
deep-water circulations (3{plus minus}2 and 20 {plus minus} 3 years,
respectively), providing the first observation-based proof for the
multi-decadal retention of (radioactive) pollutants within the Baltic
Sea. This work demonstrates the power of anthropogenic radiotracers in
investigating hydrodynamic processes in the Northwestern European
coastal areas.
A Synchronic Assessment of Google Translate, Microsoft Translator and Reverso in English<>Arabic Translation
Authors:   1Department of English Language and Translation, Applied Science Private University, Amman, Jordan, Almahasees Zakaryia
Published: July 2023

The study aimed to evaluate three multilingual MT systems that provide free English<> Arabic translation services. It assessed the effectiveness of the three systems in dealing with WHO, UN, Petra News Agency, and Arab League documents. The study adopted (LDC, 2002) intelligibility and fidelity scales to highlight the limitations and strengths of the systems understudy. The study found that Google Translate outperformed the three systems in providing intelligible and fluent output without flaws with 230 segments, equaling 57% of the corpus size, followed by Microsoft Translator with 48% and Reverso with 45% translation free of errors. On the other hand, the study found that Google Translate outperformed the other systems in terms of adequacy and fluency scales, followed by Microsoft Translator and Reverso interchangeably. However, the three systems are still unable to substitute human translators. Therefore, the study recommends conducting a diachronic study to trace the three systems' development over five years scientifically.
Протоатом и его роль в формировании величины гравитационной постоянной. Квантовые состояния протоатомов. Результаты исследования.
Authors: Чернов Андрей
Published: July 2023

В основе этого исследования лежит утверждение, что гравитационное сжатие больших космических масс имеет предел плотности сжатия. При этом первоначальная масса, состоящая из атомов, превращается в однородную, очень плотную массу (чёрную дыру), состоящую из одинаковых частиц (которые в исследовании были названы протоатомами).

В этом исследовании для определения параметров протоатома было использовано решение Шварцшильда. В результате была определена масса протоатома, а дальше через математические расчёты с использованием независимых физических постоянных была получена величина двух элементарных зарядов протоатома. Полученная величина заряда совпала с рекомендованной CODATA величиной элементарного заряда. Расхождение составило всего 0,098%, что подтвердило существование протоатома. Этот результат также интересен тем, что величина элементарного заряда была определена через другие независимые физические константы.

В этом исследовании была получена формула для расчёта величины гравитационной постоянной G. По этой формуле были произведены расчёты величины гравитационной постоянной у 24 химических элементов, взятых из всех групп таблицы Менделеева. Полученные результаты показали, что значение G может колебаться пределах тысячных и сотых долей процента. Также была определена величина гравитационной постоянной в гравитационном поле наиболее массивных чёрных дыр.

В этом исследовании по аналогии с дискретностью энергетических состояний атомов водорода, были исследованы квантовые состояния протоатомов. В результате с использованием полученных физических параметров протоатома была получена формула для расчёта квантов энергии гравитационных волн (гравитонов), испускаемых чёрными дырами. По этой формуле был рассчитан линейный ряд энергии гравитонов. Полученные значения энергии гравитонов уверенно согласуются с результатами астрофизических наблюдений гравитационных волн, которые возникли в результате слияния чёрных дыр. В ходе анализа новой формулы была определена масса электрона через 4 фундаментальные константы (G, c, q, h). Результат совпал с экспериментальной массой электрона. Были получены другие результаты, имеющие научное значение.

In this paper we deal with the problem of the optimal selection of input views, which are transmitted within an immersive video bitstream. Due to limited bitrate and pixel rate, only a subset of input views available on the encoder side can be fully transmitted to the decoder. Remaining views are – in the simplest approach – omitted or – in the newest immersive video encoding standard (MPEG immersive video, MIV) – pruned in order to remove less important information. Selecting proper views for transmission is crucial in terms of the quality of immersive video system user’s experience. In the paper we have analyzed which input views have to be selected for providing the best possible quality of virtual views, independently on the viewport requested by the viewer. Moreover, we have proposed an algorithm, which takes into account a non-uniform probability of user’s viewing direction, allowing for the increase of the subjective quality of virtual navigation for omnidirectional content.

In this paper, we propose a new gasket fractal constructed in a deterministic iterated function system (IFS) way by means of interacting ball and square sets in R^2. The gasket consists of the ball sets generated by the IFS, possessing also exact self-similarity. All this leads to a direct deduction of other properties and a clear construction methodology, including a dynamic geometry procedure with an open-source construction protocol. We also develop an extended version of the fractal in R^n. Some resulting configurations consisting of stacked 2D-fractals are plotted. We discuss about potential applications of them in some areas of science, focusing mainly on percolation models. Guidelines for future work are also provided.

Authors: Suryani Suryani , Hidayah Nurul , Sutini Titin , Al-Kofahy Lilibeth
Published: July 2023

Background: Recovering from schizophrenia is a unique process and is inï¬‚uenced by the cultural background of survivors.
Purpose: The purpose of this study is to describe the important aspects of the recovery process of Indonesian people living with schizophrenia.
Methods: This study used qualitative exploratory descriptive and data were collected through focus group discussion with seven participants at a Residents ofce on July 2018. Data were analysed using the theory of Braun and Clarke to identify key themes.
Results: Five themes arose from this study including becoming an agent of recovery, accepting yourself as you are, keeping a smile in all situations, seeking Godâ€™s help as a way to get well, and ignoring by the government.
Conclusion: It was concluded that, in the process of recovery, survivors became agents of recovery, so patient-centred care becomes very important in providing nursing care to the survivors. The result of this research can be considered for community nurses in caring for schizophrenia survivors.
Dawsonite as an indicator of multistage deformation and fluid pathways within fault zones: Insights from the Fore-Dukla Thrust Sheet, Outer Carpathians, Poland
Authors: Rybak-Ostrowska Barbara , Gąsiński Arkadiusz , Kaproń Grzegorz
Published: July 2023

The structural pattern developed within metre to microscopic scale thrust and strike-slip fault zones exposed in the Palaeogene flysch rocks of the Fore-Dukla Thrust Sheet in the south-eastern part of the Silesian Nappe, Outer Carpathians, Poland, reveals evidence for upper crustal deformation and fluid flow. Syntectonic dawsonite [NaAlCO3(OH)2] indicates the following series of deformational events within the fault zones: i) detachment and buckle folding resulting from movement along thrust faults; ii) faulting as a compensation of the shortening, resulting in the fault propagation folding, breakthrough thrust faulting and imbrications; and iii) strike-slip faulting. The microstructural pattern coupled with the growth of a related sequence of carbonate minerals within the fault zones, followed by present-day dawsonite precipitation and tufa formation, indicate a continuing influence of fluids within the Silesian Nappe up to and including modern time. Structural observations at metre to microscopic scales coupled with EDS mapping of rocks indicate that dawsonite is a unique tool for the reconstruction of subsequent deformation in the Fore-Dukla Thrust Sheet.
Roveacrinidae (Crinoidea, Articulata) from the Cenomanian and Turonian of North Africa (Agadir Basin and Anti-Atlas, Morocco, and central Tunisia): biostratigraphy and taxonomy
Authors: Gale Andrew Scott
Published: July 2023

Successions exposed in the Agadir Basin (upper Albian to middle Turonian), in the Anti-Atlas (lower Turonian) in Morocco and in central Tunisia (Cenomanian–Turonian) yield abundant microcrinoids of the family Roveacrinidae, which are described and assigned to 32 species and formae, in ten genera. The following new taxa are described: Fenestracrinus gen. nov. with the type species F. oculifer sp. nov., Discocrinus africanus sp. nov., Styracocrinus rimafera sp. nov., Lebenharticrinus quinvigintensis sp. nov., L. zitti sp. nov., Euglyphocrinus cristagalli sp. nov., E. jacobsae sp. nov., E. truncatus sp. nov., E. worthensis sp. nov., Roveacrinus gladius sp. nov., R. solisoccasum sp. nov. and Drepanocrinus wardorum sp. nov. In addition, the new subfamily Plotocrininae is erected. The stratigraphical distribution of the taxa in two important localities, Taghazout in the Agadir Basin (Morocco) and Sif el Tella, Djebel Mhrila (central Tunisia), is provided. The faunas from the uppermost Albian and lowermost Cenomanian of the Agadir Basin are nearly identical to those recorded from central Texas, USA, some 5,300 km away, and permit a detailed correlation (microcrinoid biozones CeR1 and CeR2) to be established across the southern part of the Western Tethys, independently supported by new ammonite records. For the middle and upper Cenomanian, rather few detailed records of microcrinoids are available elsewhere, and the North African record forms the basis for a new zonation (CeR3–CeR6). The distribution of Turonian Roveacrinidae in North Africa is evidently very similar to that described in the Anglo-Paris Basin, and zones TuR1–3, TuR9, 10 and 14 are recognised for the first time in the Tethys.
A new species of Hystrix (Rodentia: Hystricidae) from the Pliocene site of Węże 1 in southern Poland
Authors: Czernielewski Michał
Published: July 2023

The specific name velunensis is established to encompass porcupine remains ( Hystrix Linnæus, 1758) recovered from the Pliocene site of Węże 1 in southern Poland. The studied specimen was previously assigned either to H. primigenia (Wagner, 1848) or H. depereti Sen, 2001, however it can be distinguished from these species and other fossil Hystricidae by its distinct occlusal morphology, most importantly the presence of an anterolingual flexus dissecting the anteroloph of P4. Hystrix velunensis sp. nov. was probably closely related to H. primigenia and H. depereti. A previously undescribed specimen from the nearby site of Węże 2 most probably belongs to H. refossa Gervais, 1852b, which would be the first known occurrence of this species in Poland.

Javanese turmeric (Curcuma xanthorrhiza Roxb.) is important for study due to its increasing economic value in many aspects including marker-associated compounds for curcuminoids and xanthorrhizol. This systematic review aimed to summarize and find information about C. xanthorrhiza starting from its pharmacological activity and mechanism as an anticancer, anti-inflammatory, and antioxidant extraction process, and cultivation techniques. The data were obtained from relevant journals in national and international scientific databases PubMed, Scopus, Google Scholar, Web of Science, SINTA, ScienceDirect, and Wiley Online from 2000 to 2023. Results showed that from the perspective of anti-inflammatory pharmacological activities, xanthorrhizol inhibits pain response and inflammatory response. Its antioxidant activity showed a contribution to inhibiting oxidation which also successfully inhibits cancer cell proliferation. The extraction method of xanthorrhizol and curcuminoid compounds with Ultrasonic-Assisted Extraction (UAE) 20-2000 kHz performs better than other methods. C. xanthorrhiza cultivation techniques under shading produce better rhizomes. Based on research on cultivation techniques, extraction methods, and pharmacological activities, C. xanthorrhiza has an important role in the future.

PURPOSE. Determining standard value of individual fire risk (IFR) is necessary to improve management decisions in the field of fire safety in Vietnam. As evidenced in practice, in countries with the established IFR standard the process of supporting management decisions in fire safety has been improved. Therefore, reasonable IFR standard establishment and its application in models and algorithms for making management decisions to reduce fire risks is a crucial task that is solved in this article. METHODS. Mathematical statistics and system analysis methods are used in the work. FINDINGS. Based on the results of the study, algorithm for determining and standard individual fire risk specific value for Vietnam have been obtained as well as model and algorithm for management decisions support to ensure fire safety in Vietnam. RESEARCH APPLICATION FIELD. The results of the study can be used as rationale for management decisions to ensure fire safety in Vietnam. CONCLUSIONS. Based on the developed algorithm, it has been established that individual fire risk standard value for Vietnam should be 1.34⋅10–6 victims/inh. year. This means that death toll from fires in Vietnam should not exceed 1.34 victims per 1 million people a year. Standard individual fire risk value for Vietnam should range within 3.7⋅10–8 < 1.34⋅10–6 < 3.7⋅10–6, which has been established by the authors in previous studies. Applying the model and algorithm for supporting management decisions to ensure fire safety in Vietnam will increase the country’s fire protection effectiveness.

A Study on the Location and Literary Representation of the Places Around Yongmunsan(龍門山) in Yangpyong(楊平)
Authors:   Institute For Kyeongki Cultural Studies, Kim Myo Jung
Published: July 2023

This article was designed to study the location and literary representation patterns of surrounding places, starting with Yongmunsan(龍門山) in the Yangpyong(楊平) area of Gyeonggi-do. Accordingly, Chapter 2 attempted to determine the location of Yangpyong while also verifying the surrounding places through literature data. This is meaningful in that it is a basic work to reveal the place of a new place through mutual negotiations between geography and literature.
Next, in Chapter 3, the meaning of the space around Yangpyong Yongmunsan was sequentially confirmed. First, the beauty of the place, Yongmunsan travel, and the description of Seunggyeong were captured. Accordingly, it was found that the poems written by writers in Yongmunsan contained the beauty of the arithmetic space itself and the excellence of the surrounding landscape. This is meaningful in that it is the most superficial and most essential process in the process of recognizing the space called Yongmunsan.
Second, we looked at the reproduction of the meaning of Ungyeseowon(雲溪書院), Sesimjung(洗心亭), and Hermit places. Here, a new space called Ungyeseowon Confucian Academy and Sesimjung, located around Yongmunsan, was found. In addition, it was revealed that these places are related to the Yongmun(龍門) Jowook(趙昱) and that their meaning as Hermit places has been reproduced until later generations.
Third, Lee Ho-min(李好閔), Lee Gyung-eom(李景嚴)'s father and son Byeolseo(別墅), Sacheonjang(斜川庄), and Sacheonpalgyong(斜川八景) were examined. Here, by determining the space called Sacheonjang and looking at Sacheon Palgyong, the literary shape and place of the places around Yongmunsan were revealed.

The 2019 Venezuelan Blackout and the consequences of cyber uncertainty
Authors: Devanny Joseph , Goldoni Luiz Rogério Franco , Medeiros Breno Pauli
Published: July 2023

In March 2019, Nicolás Maduro claimed that the blackout in Venezuela was caused by U.S. cyber-attacks. This statement was promptly denied by Mike Pompeo, the U.S. Secretary of State. Irrespective of the truth of Maduro’s allegation, this episode highlights the diplomatic challenges for states in the contemporary information environment, in which contested narratives proliferate and embed themselves more durably because of the deterritoriality and disintermediation of the Internet. This is particularly true in the context of an emerging pattern of state actors conducting cyber operations against critical infrastructure in other states. The cumulative impact of these different strands is that states will likely struggle to control the perception of their intentions in the cyber domain, not only amongst governments but across the many national audiences that comprise the global public sphere. Focusing on Maduro’s allegation, this article analyses the political utility of cyber uncertainty, and its corresponding implications for states’ cyber strategies and decisionmaking.
Do Haiti ao Rio de Janeiro e vice-versa: a pacificação enquanto pilar da governamentalidade brasileira acerca da paz
Authors: Hoff Natali , Blanco Ramon
Published: July 2023

Tendo em conta a crescente aparição do termo pacificação no vocabulário político brasileiro e a sua constante associação ao uso de políticas militarizadas para o combate a grupos criminosos e para a retomada das regiões periféricas dominadas por esses grupos, o presente artigo analisa como a ideia de pacificação está no centro das práticas brasileiras de construção da paz - seja em âmbito doméstico ou internacional. Dessa forma, entende-se que a ação militar é um aspecto central da governamentalidade brasileira no que toca a construção da paz, nacional e internacionalmente. Para aprofundar essa temática, o artigo analisa de que maneira a experiência brasileira no comando militar da Missão das Nações Unidas de Estabilização no Haiti (MINUSTAH) está relacionada com as práticas e racionalidades presentes nas Unidades de Polícia Pacificadoras (UPPs) cariocas e vice e versa. Para isso, esse trabalho está dividido em duas seções. A primeira seção se direciona a discutir como a palavra pacificação acaba por formar e informar aspectos importantes da governamentalidade brasileira concernente à paz. A segunda seção, por sua vez, se direciona analisar as conexões existentes entre as práticas pacificadoras empreendidas pelo exército brasileiro no Haiti e a política de pacificação do Rio de Janeiro.
Análise estrutural das estratégias de segurança cibernética do Brasil e dos Estados Unidos

Published: July 2023

Com a contínua difusão do uso da Internet, cada vez mais países produzem estratégias de cibersegurança. Nesse contexto, é comum que documentos elaborados por diferentes Estados sejam analisados comparativamente, a fim de se estabelecer pontos de convergência e aspectos que possam ser aprimorados. O Brasil publicou a sua primeira Estratégia Nacional de Segurança Cibernética (E-Ciber), em fevereiro de 2020. Trata-se, portanto, de um documento recente, com ainda poucas análises acerca dele. Por sua vez, a Estratégia Cibernética Nacional dos Estados Unidos (NCS) foi publicada em setembro de 2018, sendo apresentada como a primeira estratégia da área “totalmente articulada em 15 anos”. Neste artigo é feita uma comparação estrutural do documento brasileiro com o estadunidense, além de uma análise fundamentada no framework proposto por Luijiif et al. (2013), que se baseia na avaliação de 19 estratégias nacionais de segurança cibernética, de 18 países, a partir da qual os autores produziram um modelo estrutural mínimo. Trata-se, portanto, de uma pesquisa exploratória, cuja metodologia é de política comparada, com técnica de coleta de dados de documentação indireta e técnica de análise de dados qualitativa. Na conclusão, demonstra-se que a Estratégia brasileira foi desenvolvida com metodologia bottom-up, a partir da realização de reuniões de diagnóstico, debates e consultas públicas. Em contraste, a Estratégia estadunidense foi estruturada com metodologia top-down, uma vez que antes que o documento fosse desenvolvido, os objetivos a serem atingidos já estavam definidos. Também se verifica que a Estratégia brasileira possui todos os tópicos propostos por Luijiif et al., exceto o glossário, enquanto que o documento estadunidense dispõe de apenas quatro dos nove tópicos propostos. Apesar dessa diferença estrutural, verifica-se uma convergência nas ações definidas por ambas as estratégias.
European Union military operations and global security: ambitions and reality
Authors: Aguilar Sergio Luiz Cruz
Published: July 2023

In the last twenty years, the European Union (EU) has made notable efforts in improving its military capabilities to react to crises. The Union launched crisis management missions and operations, aiming to play a relevant role in the field of international security. Thirteen military operations and missions were established amongst its overseas action to date. Notwithstanding, the results are questionable, i.e. the positive relationship between what the EU says, and its concrete action in practice. The paper aims to present what is the real role of EU military operations by arguing that although high ambitions the Union’s military interventions are still limited. It is demonstrated by using a model with proxies from inputs to impacts through which I analyse perceptions and intentions and how they have been translated into effective implementation. I used quantitative data combined with certain qualitative remarks collected from primary and secondary sources. It concludes that the EU military operations remain more as ambitions than to project its best features in favour of a better world security environment
A Utilidade Estratégica do Míssil de Cruzeiro
Authors: Rosa Carlos Eduardo Valle
Published: July 2023

O artigo discute o potencial estratégico de emprego do míssil de cruzeiro no contexto de uma campanha aeroestratégica. Inicialmente, especifica as características dos mísseis em geral, com a finalidade de se estabelecer uma definição, ausente no léxico doutrinário nacional, para mísseis de cruzeiro. Isso permite posicionar o AV-MTC e o MICLA-BR em um contexto classificatório. O artigo adentra em uma revisão teórica que busca identificar argumentos sobre a questão do bombardeio aéreo contra centros de gravidade estratégicos, no âmbito da teoria do poder aéreo. Com base nos construtos teóricos de Vallance (1996) e Warden III (2015), o artigo analisa a forma pela qual o míssil de cruzeiro poderia ser utilizado em uma campanha aeroestratégica. O artigo chega às seguintes conclusões: propõe uma definição de míssil cruzeiro para o glossário brasileiro; infere que a teoria do poder aéreo sustenta o emprego estratégico de mísseis de cruzeiro; levanta fatores operacionais a serem considerados no emprego dos mísseis de cruzeiro na campanha aeroestratégica; evidencia critérios para a seleção de alvos estratégicos no emprego dos mísseis; e aponta tendências desse tipo de emprego que podem ser consideradas no caso brasileiro.
