Transnational Turbulence: Volatility Spillover from the U.S. Political Uncertainties to the Emerging Economies of South Asia
Authors: Mushtaq Hina , Qayyum Abdul , Ishtiaq Muhammad
Published: December 2024

The study explores the dynamics of volatility spillover from U.S. political uncertainties to the emerging economies of South Asia by using the Markov-Switching and a DCC-GARCH model. By using the daily data from 2000 to 2024, the study has found that the U.S. political risk has significantly affected the majority of the South Asian stock markets during the first regime. On the other hand, it has affected the stock markets of Bangladesh and Maldives during the second regime. Moreover, the transition probabilities also show a higher likelihood of remaining in the second regime of high volatility along with longer expected durations. Then, the DCC-GARCH model confirms the dependence of these markets' returns on their lagged squared residuals. Overall, the volatility spillover from the U.S. political uncertainties exists in the short run to Indian, Bangladeshi, and Maldivian stock markets, while this spillover exists in the long run for all the stock markets.

Published: December 2024

This study examines the walkability perceptions of residents in Johar Block-13, Karachi, focusing on pedestrian satisfaction and infrastructure needs. Using surveys and field observations, the research identifies key concerns, including poor sidewalk maintenance, limited crossing accessibility, inadequate lighting, and safety issues, with 76% of respondents feeling unsafe while walking. Additionally, noise pollution, vehicle congestion, and the lack of pedestrian-friendly amenities detract from the overall walkability experience. Results indicate significant dissatisfaction with the current infrastructure, especially regarding accessibility for vulnerable groups, including the elderly and disabled. The findings underscore a need for targeted improvements to foster a safer, more accessible environment, enhancing pedestrian activity and quality of life in Johar Block-13. The study's findings may help policymakers and urban planners design a city that can promote walking.

Published: December 2024

Cultivating lettuce (Lactuca sativa L.) using plant growth-promoting rhizobacteria (PGPR) in Sorong Regency is uncommon, limiting production despite the high market potential. This study aims to evaluate the effect of PGPR and identify the optimal concentration to improve lettuce growth and yield. The research was conducted in Malawili Village, Sorong Regency, Indonesia, using a randomized block design (RBD) with four treatments: P0 (7.5 mL/L), P1 (10.5 mL/L), P2 (13.5 mL/L), and P3 (16.5 mL/L). Results revealed that PGPR significantly enhanced growth parameters, including plant height, leaf number, fresh biomass weight, biomass weight per plot, fresh weight for consumption, and root length. Among all treatments, 13.5 mL/L (P2) demonstrated the best outcomes, with plant height reaching 14.6 cm, fresh biomass weight of 633.3 g, and root length of 9.6 cm. PGPR application at appropriate concentrations effectively stimulates growth, increases nutrient uptake, and improves yield. These findings underline PGPR's potential to enhance lettuce production sustainably.

Published: December 2024

Based on the replica exchange algorithm of the Monte Carlo method, the influence of an external magnetic field on phase transitions and thermodynamic properties of the two-dimensional antiferromagnetic Potts model with the number of spin states q = 4 on a hexagonal lattice was studied. The studies were conducted in the range of external magnetic field values of 0.0 ≤ h ≤ 10.0. The magnetic field is measured in relative units of exchange interaction between nearest neighbors |J1|. The magnetic structures of the ground state were obtained, and the nature of phase transitions in the considered field range was analyzed. It has been established that in the intervals 0.0 ≤ h ≤ 3.0 and 6.0 ≤ h ≤ 6.5 a first-order phase transition is observed. It is shown that at the external magnetic field values h = 3.5 and 5.5, the system is frustrated, and in the magnetic field intervals 4.0 ≤ h ≤ 5.0 and 7.0 ≤ h ≤ 8.5, the system approaches the frustration regime. It was found that strong magnetic fields (h ≥ 9.0) suppress the phase transition in the system.

Published: December 2024

The soils of the sea coasts function on the contact of terrigenous runoff and the effects of seawater, which provides a unique geochemical environment. In part, the processes of migration and accumulation of elements can be provided by the processes of formation and oxidation of iron sulfides. The content and spatial distribution of trace elements in the soils of the marshes of the Pomor coast of the White Sea were studied. The work was carried out near the village of Kolezhma, Belomorsky district, Republic of Karelia. The study showed that the studied soils are characterized by an increased content of trace elements such as As and Se, which are usually associated with the presence of metal sulfides in marine sediments. The content of Fe was up to 27 300 ppm and Mn – up to 1500 ppm, which is generally typical for taiga landscapes. At the same time, the geochemical fate of Fe and Mn in coastal soils diverges, probably partly due to the participation of Fe in mineral transitions from sulfides to sulfates. Ni and Cr were present in soils in concentrations comparable to the zonal soils of the region. Only As and Se might be potentially toxic in the case of the use of the tombolo as hayfield.

Published: December 2024

Using the method of high-throughput sequencing of the 16S rRNA gene, the taxonomic composition of soil bacterial communities (Technosol and Retisol) near the salt dump of a potassium enterprise (Solikamsk, Perm region) was analyzed. Soil samples without plants and the rhizosphere of plants of the species Calamagrostis epigeios (L.) Roth) from areas located 1–1.5, 8, 780 m and 11 km from the salt dump were studied. It was found that bacteria from the phyla Pseudomonadota, Bacteroidota, Actinomycetota, Acidobacteriota, Verrucomicrobiota and Gemmatimonadota predominated in all soil samples. Halite waste had the greatest impact on the taxonomic composition of bacterial communities on the soils of areas (in the salinity zone) located in the immediate vicinity of the salt dump (1–1.5 m). In soil samples without plants collected in these areas, relative to soils samples without salinity (at a distance of 8, 780 m, 11 km from the salt dump), bacteria of the order “Candidatus Actinomarinales” predominated; the proportion in the bacterial communities of representatives of the phyla Acidobacteriota, Verrucomicrobiota, class Actinobacteria and the Chitinophagaceae family, the proportion of bacteria of the family Xanthomonadaceae increased. In rhizosphere bacterial communities of the plants growing in the salinity zone, the proportion of representatives of the phylum Acidobacteriota and the families Chitinophagaceae, Enterobacteriaceae decreased, and the proportion of the families Xanthomonadaceae and Flavobacteriaceae increased. The influence of the salt dump on the soil bacterial communities from areas located 8 m and 730 m from the salt dump was revealed, manifested in the presence of representatives of the order “Candidatus Actinomarinales” (1.4–1.6%), families Nitrosomonadaceae (3.0–6.1%), Saprospiraceae (1.0–1.9%), the genus Ilumatobacter (1.6–2.8%) and unculturable bacteria of the family Rhodanobacteraceae (1.3–1.5%).
Transregional Security Impacts of the Special Military Operation and Strategic Interests of the United States and China (Part 2)
Authors: Yixiang Sun
Published: December 2024

The article analyzes the evolving dynamics of global strategic interests amid major international conflicts, focusing on the geopolitical consequences of the Russia-Ukraine conflict and the strategic maneuvers of key powers like the United States, NATO, China, and Russia. It explores how the U.S. has utilized the conflict to realign its global influence, strengthen NATO, and project power in the Indo-Pacific, emphasizing its intention to counter both Russian and Chinese influence. The U.S. benefits economically from Europe's growing dependency, while using the conflict to enhance military-industrial partnerships and sanctioning regimes targeting Russia and China. China’s strategic realignment, in response, seeks to bolster Sino-Russian cooperation and expand influence in the Asia-Pacific through initiatives like the "Asian Mediterranean" concept, which envisions deeper Eurasian integration. The author outlines China’s attempts to balance its maritime and land power dynamics while navigating heightened U.S. efforts to isolate it diplomatically and militarily. It also highlights the potential for high-tech cooperation between China and Russia as a countermeasure to Western sanctions and technological blockades.
Kamala Harris: 'A New Sign of a Seismic Shift' in 2024 Presidential Race
Authors: Shvedova N. A
Published: December 2024

July 21, 2024, will take its place in the political history of the United States: President J. Biden withdrew from the presidential race for a second term and proposed Vice President Kamala Harris as his replacement on the list of candidates. The inevitability of changing the Democratic candidature in the midst of the campaign was driven by J. Biden’s evident fiasco in the "first" confrontation with a Republican rival, as well as his advanced age. The drama of the events reached its peak, and overnight, K. Harris gained a chance to become the leading contender for her party’s nomination. Academician G.A. Arbatov once wrote: "Politics is a resultant force that consists of many applied forces and factors" [12]. It was in this vein that the events of the 2024 presidential elections unfolded, where the intrigue of the winner remained until the very end.
THE INFLUENCE OF MEDIEVAL RUSSIAN LITERATURE ON THE EPICS OF EASTERN SIBERIA
Authors:   Institute of Russian Literature (Pushkinskii Dom) of the Russian Academy of Sciences St. Petersburg, Ivanova Tatyana G.
Published: December 2024

This article briefly highlights the history of the settlement of the two northeastern regions of Siberia — the areas of the Indigirka River (Russkoe Ust’e) and the Kolyma River — and discusses the history of the process of the recording of the local epics. The study pays particular attention to the influence of the medieval Russian version of Flavius Josephus’s History of the Jewish War on the local epics. The article analyzes variants of the epic “Mikhail Danilovich the Underage Hero,” which makes use of the name of Titus, the destroyer of the Jewish temple in Jerusalem. The author proposes the hypothesis that the name Elizar, which is found in the episode of “The Raid of the Lithuanians,” was also borrowed from the History of the Jewish War. For the Russian people of the Indigirka and Kolyma regions, this connection of the oral song and epic tradition with handwritten texts became one of many ways to establish their national identity in the 17th and 18th centuries.
THE KOMSOMOL CENTRAL COMMITTEE STAFF AS CRITICS: THE LIMITS OF CENSORED LITERATURE IN THE RESOLUTIONS ON THE PUBLISHING HOUSE MOLODAIA GVARDIA IN THE LATE 1950S AND EARLY 1960S
Authors:   University of Pennsylvania, Philadelphia, Lukin Maxim Yu.
Published: December 2024

The article analyzes the notes and resolutions of the Komsomol Central Committee that evaluated the activities of the publishing house Molodaia Gvardiia. The author reconstructs normative perceptions of censored youth literature through critical comments on books published in the late 1950s and early 1960s by those editorial departments of this publishing house that specialized in literature about young Soviet pioneers, Russian poetry, and science fiction. The censors criticized references to extramarital affairs and romantic relationships, intricacies of human emotions and political statements conveyed in an “Aesopian language.” Furthermore, they condemned the use of irony, which they interpreted as ambiguity, and labeled experiments with innovative poetic forms as “formalistic twists” (vyverty). Criticism in the notes and resolutions of the Komsomol Central Committee established boundaries for permissible discourse in censored youth literature. At the same time, it led to concrete repressive consequences: reprimands for editors and problems with further publications for authors. Therefore, the Komsomol Central Committee can be considered a part of the institutional system that governed the production of youth culture in the USSR.
WHAT MAKES FOR AN EFFECTIVE GRAMMAR PRESENTATION?: PEER, SELF- AND TEACHER TRAINER EVALUATION OF MICRO-TEACHING
Authors: Đorđević Ana , Vitaz Milica
Published: December 2024

In order to identify the elements of grammar teaching which most
influence the perception of its effectiveness, we looked into the link between
general evaluations of students’ micro-teaching grammar presentations (an
overall grade) and the assessments of their individual aspects, such as studentteacher personality, their non-verbal communication, the teaching method
employed and the appropriateness of the materials and the activities used. The
study involved 36 final year students of English language, literature and culture
at a state university in Serbia who engaged in micro-teaching as part of their
English language teaching methodology 2 coursework. After each classroombased 5-minute grammar presentation, the same online questionnaire was
completed by student teachers themselves (self-evaluation), their fellow students
acting as language learners (anonymous peer evaluation) and two university ELT
methodology teachers (397 evaluations in total), thus enabling us to investigate
the potential differences in the perceptions of the grammar teaching depending
on the source of evaluation (peer, self- or teacher trainer). A thematic analysis
was conducted on the participants’ responses to an open-ended question
regarding the key element that made the grammar presentation successful.
Correlational analysis revealed that the strongest association occurred between
the perceived level of grammar presentation effectiveness and the positive
student teacher characteristics, while the qualitative data analysis showed that
the student teacher personality and their teaching style consistent with the
constructivist theory of learning were almost equally cited as the main
contributors to the positive perception of micro-teaching. Differences between
the perceptions of different groups of evaluators were identified and accounted
for in both types of research inquiry.

UNRELIABLE NARRATIVE STRATEGY IN AUTOBIOGRAPHICAL WRITING – THE CASE OF SPARE BY PRINCE HARRY
Authors: Ignjatović Sanja
Published: December 2024

The paper problematizes unreliable narration in autobiographical
writing, exploring the rhetorical effects produced in the process of
narrativization that challenge genre conventions in terms of the relativization of
objective reality in subjective interpretations. Therefore, the paper analyzes
discordant and estranging narration as the outcome of textual effects and the
rhetorical layering produced by the author-narrator. The theoretical grounds for
the exploration of the types of unreliable narration involves a discussion on
authorial fictionalization, the role of fictionality in non-fiction as the rhetorical
veil between story and narrative discourse, and textual and figurative narcissism.
Illustrations come from Spare (2023), the memoir authored and published by
Prince Harry, The Duke of Sussex, and his ghostwriter J. R. Moehringer.

WORLD COFFEE CULTURE: COFFEE HOUSES AND CAFÉS LITTÉRAIRES – FOCUS ON ITALY
Authors: Ceramella Nick
Published: December 2024

The idea to write this article was inspired by a Ugandan-born English
writer, Anthony Capella, who is the author of the novel The Various Flavours of
Coffee (2008), in which coffee flavours are compared with the varying ‘flavours’
of love depending on the protagonist’s many flirts. I will argue that coffee
traditionally accompanies emotional experiences to fight against stress and
moodiness or it can be seen as a shelter or a facilitator of relationships. As widely
acknowledged, coffee is some sort of ritual enjoyed, first in the morning for a
caffeine boost to power your day, during coffee breaks, and after meals. We will
see how such functions represent the role coffee had throughout history. Initially,
coffee houses grew as meeting places for discussing business and matters of high
historic and social relevance. Then, they acquired a key role in the literature
world, and became literary cafés. Thus, it is not incidental that poems, short
stories, music compositions, and even novels have been dedicated to coffee and
cafés have been used as the ideal place where stories were set. Besides referring
to some leading world writers and artists, I will focus on some of the most
prominent Italian examples, including Goldoni’s La bottega del caffè (1750),
Luigi Pirandello’s L’ultimo caffè (1912), and among contemporary writers to
Luciano De Crescenzo with Il caffè sospeso (2017). You can bump into a ‘caffé
letterario’ even in the remotest areas of the country.

An Efficient and Robust Combined Feature Extraction Technique for Face Recognition Systems
Authors: H. AL-Abboodi Rana , Al-Ani Ayad A.
Published: December 2024

Face recognition has long attracted a lot of interest from the research and market communities due toits many possibilities across numerous sectors, but it has proven to be exceedingly difficult to deploy in real-time applications. Over the years, several face recognition algorithms and their variations have been created. In this paper, an integrating STIP and SURF for a robust feature extraction approach is proposed. This approach consists of four steps: In the first step, researchers are collecting the input images. In the next step, image preprocessing using a Gaussian filter is used. Then, image segmentation is applied using Region of Interest (ROI). The Spatial-Temporal Interest Point (STIP) is employed to extract the features related to facial behaviors from Facial Action Units (FAUs). The most effective approach for object recognition in image processing that applies feature descriptors is a Histogram of Oriented Gradients (HOG). In the last phase, use the feature selection process using SURF (Speeded-up Robust Features). This proposed approach achieved (0.25 ms) better performance than the traditional approach.
Optimizing QoS in Wireless Sensor Networks: A Review of Advanced Traffic Control Protocols and Techniques
Authors: Arif Nadhom Obaid Mohammed , Saeed Hameed Zaynab , Israa Ali AlNeami
Published: December 2024

In wireless sensor network technology (WSNs) the proper congestion processing is the essential key to prevent the parameters of QoS from facing intense loss such as Likelihood of occurrence output reduction and also it may lead to maximize the consumed energy and it also reflect on the increase of the end-to-end time delivery side by side with a noticeable decrease in the percentage of transmitted packet arrival at the destination end. Thus, evolving more superior technology is consider to be one of the most significant challenge in (WSNs) that help to deal with issues like avidness, detection and control in WSNs. This paper review most updated protocols to mitigate the dilemmas of congestion in the WSNs based on the mechanism of congestion’s innate behavior. The protocol categories can be divided into three divisions which are traffic based, resource based and hybrid. The first protocol category (traffic-based) is also witnessed more subdivide based on either the techniques of end-to-end transmission or hop-by-hop. Both the establishment procedure of route and the exploit of active bandwidth techniques. It is also important to indicate that inner operational process of the attenuation linked to congestion protocols are discuss in this paper. Lastly. An intensive study is exploited in this paper to analyze congestion protocols in connection with different performance standards in order to determine which a specific protocol category case is worth to develop. The performance survey shows that the difficulties of accurate detection to the congestion for a particular network if it is only considering the protocols class attitude when it alters with applicable platform and a metric on its own.

Published: December 2024

Foi realizado um levantamento das espécies desembarcadas pela frota de pesca de arrasto de fundo do Rio Grande - RS entre os anos de 2001 e 2015. As amostragens ocorreram de modo descontínuo ao longo desse período. O intuito deste estudo foi elucidar a estrutura taxonômica do recurso “raia” na plataforma sul do Brasil, uma importante área para a reprodução desse grupo. O conhecimento das espécies que compõem esse recurso é importante para a conservação. Dos 2360 exemplares amostrados, 15 taxa foram identiϔicados no nível de espécie. As espécies mais comuns foram Rioraja agassizii (n = 617; 26,1%), Sympterygia bonapartii (n= 481; 20,4%), Atlantoraja castelnaui (n = 349; 14,8%), Atlantoraja cyclophora (n = 299; 12,7%) e Zapteryx brevirostris (n = 279; 11,8%). Em menor frequência, foram registradas as seguintes espécies: Sympterygia acuta (4,4%), Atlantoraja platana (1,9%), Dasyatis hypostigma (1,4%), Pseudobatos horkelii (0,6%), Myliobatis goodei (0,5%), Gymnura altavela (0,3%), Psammobatis extenta (0,2%), Psammobatis rutrum (0,2%), Psammobatis lentiginosa (0,1%) e Myliobatis freminvillei (0,04%). Dentre as raias, há varias categorias usadas localmente pelos pescadores na hora de separar os peixes para processamento nas industrias. Os Rajiformes são conhecidos como parte de uma categoria generalizada chamada "emplastro" pelos pescadores para comercialização. Essa categoria inclui A. cyclophora, A. platana, R. agassizii e juvenis de A. castelnaui. No entanto, foi observado que, dentro dessa categoria de pesca, os Myliobatiformes, especialmente as espécies menores, frequentemente são agrupados dentro do "emplastro". Os pescadores também classiϔicam o "emplastro" em "emplastro amarelo", correspondente a S. acuta e nadadeiras peitorais de Myliobatiformes, e "emplastro bicudo", que se refere a S. acuta. As carcaças de A. castelnaui são processadasseparadamente e agrupadas como "emplastro pintado","raia pintada","raia marcela" ou "raia chita". Os Rhinopristiformessão classiϔicados como "raia viola"(peixe-guitarra brasileiro), correspondente a P. horkelii, e "raia banjo" (raia viola de focinho curto), correspondente a Z. brevirostris. Houve um predomínio de fêmeas (1258; 53,3%) em relação aos machos (n = 666, 28,2%) assim como um número considerável de espécimes maduros(n = 545; 23,1%). A modalidade de arrasto parelha foi a mais utilizada (82%) e demonstrou ter maior propensão a capturar espécies de tamanhos médios a grandes.

Authors: Melo-Lima Valeria Maria , Da Mata-Oliveira Igor , Lucena Frédou Flavia , Coelho Filho Petrônio Alves
Published: December 2024

This study evaluated the sex ratio and seasonal abundance of the seabob shrimp Xiphopenaeus kroyeri at the mouth of the São Francisco River, Northeastern Brazil, from 2008 to 2009. A total of 3,072 individuals were collected, measured for carapace length (in mm), and classified by sex and developmental stage. Shrimps were categorized according to the capture period (dry or rainy season). Size distribution ranged from 8-34 mm, with the highest concentration in the 18-20 mm class. Females were significantly more abundant and larger, predominating in most size classes. Juveniles represented 3.5% of the specimens, being more frequent in the dry season. There was no difference in adult participation between the analyzed periods. The dominance of females may be influenced by fishing selectivity, which tends to capture larger individuals. This study provides insights for the sustainable management of X. kroyeri stocks, highlighting the importance of management measures to maintain population viability, especially in the face of overfishing of reproductive stocks.

This note records the preliminary results obtained during the course of the first pilot project to investigate the adaptability and zootechnical performance of dusky grouper Epinephelus marginatus in northeastern Brazil. The project started with first juvenile transport from Prime Seafood Marine Farm, Alcobaça – BA - Brazil, to Mirante Pescados, Cascavel – CE – Brazil, and is running with individuals maintained in a float net cage, enclosed in a frame tank padded with plastic liner, with a land-based Recirculating Aquaculture System (RAS). The biological adaptation was evaluated by fish survival and feed intake. Growth performance by zootechnical indexes was estimated through biometric measurements. During this initial report period (14th November 2021 to 9th February 2022)  fish were hand-fed twice daily (8:00 a.m. and 5:00 p.m.) at a rate of 1.5 % total biomass. The water quality parameters were monitored regularly, at least once a week, and commercial probiotic was added to the water tank. Water quality remained in the range tolerable for the species and to February 2022, survival is 100%. The feeding behavior has been immediate consumption of all offered food, demonstrating the biological adaptability of the dusk grouper. Over the 87-days report period, the juveniles showed a significant (P < 0.05) improvement in growth performance and reached an average weight and length of 290.2 ± 4.7 g and 25.03 ± 0.1 cm. Likewise, the mean apparent food ration converse and specific growth rate were 1.33 and 0.77 (% -day). The preliminary pilot project has already accomplished the first successful transport of groupers to Ceará – Brazil; attest the ability of the dusky grouper E. marginatus to be adapted to a new hot and dry environment and the preliminary growth performance indicates there is great potential of dusky grouper production in northeastern Brazil.

O estudo dos recursos naturais renováveis implica desenvolver processos de gestão considerando que os recursos pesqueiros são utilizados comercialmente no limite para garantir um esforço de pesca que retornará um valor igual ao custo de exploração desses recursos. O presente estudo teve como objetivo avaliar, do ponto de vista econômico, a pesca de atuns e afins enfocando a modelagem bioeconômica das pescarias, e integrou o Projeto PROTUNA. Levantaram-se os parâmetros biológicos e econômicos para uma análise bioeconômica e simulou-se a dinâmica da atividade pesqueira para subsidiar medidas de gestão às operações de pesca da frota atuneira sediada em Areia Branca (RN). Os dados biológicos foram obtidos na Base Nacional de Dados de Atuns e Afins – BNDA, enquanto os dados econômicos foram fornecidos pela Associação dos Proprietários de Barcos de Pesca do Estado do Rio Grande do Norte – ASPERN. Utilizou-se um modelo bioeconômico para pescarias simples, como as de pequena escala, denominado Modelagem Econômica – MECON, que permite identificar possíveis estratégias de gestão. A simulação indica que o recurso se encontrava sobrexplotado e, provavelmente, um ponto de equilíbrio poderia ser alcançado com uma redução de 32% no esforço de pesca, em número de embarcações, e de 20% na mortalidade por pesca, com possibilidade de aumentar investimentos na capturabilidade, frente aos níveis de esforço exercidos.

The Guiana dolphin, Sotalia guianensis, classified as 'Vulnerable' to extinction in Brazil, exhibits a particularly small population within Mucuripe embayment, Ceará state, Northeastern Brazil. This study investigated their behavioral responses from October 2019 to May 2021 as part of the environmental licensing requirements for dredging and land reclamation activities. Thirty-two boat surveys were conducted, with dolphins observed in 97% of them. Two 'unusual' responses to the presence of boats and swimmers were noted: a neutral reaction, when a group of five dolphins continued foraging despite nearby swimmers; and a positive response, when three dolphins deliberately approached the research boat, engaging in spy-hopping and sideways swimming, suggesting curiosity towards our presence. These unusual reactions highlight concerns regarding potential human-dolphin interactions in Mucuripe embayment, underscoring the need for continuous systematic monitoring. Such efforts are crucial to provide the appropriate subsidies aimed at preserving natural dolphin behaviors. 
Keywords: Cetaceans, marine mammals, endangered species, behavior, interactions, Mucuripe embayment.
EFFECTS OF ARTIFICIAL BEACH NOURISHMENT ON WATER QUALITY AND MARINE BIOTA: A CRITICAL REVIEW
Authors: Nunes da Silva Luiz Carlos , Barbosa Viana Michael
Published: December 2024

O presente trabalho tem como objetivo apresentar, por meio de uma revisão crítica da literatura, um panorama dos principais efeitos das obras da engorda de praias na qualidade da água e na biota marinha, considerando as principais publicações científicas dos últimos vinte e cinco anos. No levantamento realizado, a engorda artificial de praia tem se mostrado eficiente no combate ao processo de erosão costeira, e a maioria dessas pesquisas se concentraram em praias do continente europeu e nos EUA. Após a conclusão das obras da engorda, os principais efeitos observados foram elevação da turbidez da água, presença de bactérias indicadoras de contaminação fecal no sedimento da área da engorda, alterações na composição da comunidade bentônica e o desaparecimento dos prados de Posidonia oceanica. A maioria desses efeitos tiveram magnitude de impacto temporária e alguns deles apresentaram tempo de recuperação de até quatro anos. Por último, sugere-se a melhoria dos programas de monitoramento dos efeitos da engorda artificial de praia, considerando que a falta de gestão e planejamento entre as partes interessadas nas obras de engorda podem contribuir para intensificar esses efeitos no ecossistema marinho.

Authors: Vagena Akrivi
Published: December 2024

Tourism is an essential economic sector in Greece, contributing over 25% to its GDP. The hotel sector is a significant component of the tourism industry, which plays also a vital role in the economy of Greece.

However, its environmental impact—manifesting through high energy usage, water consumption, and waste generation—poses significant challenges. This study explores sustainable practices within Greek hotels, emphasizing the adoption of circular economy principles, green certifications, and guest engagement strategies. Using case studies, published data from surveys, and policy analysis, the study identifies barriers such as financial limitations and infrastructural gaps.

Recommendations include financial incentives, regional policy customization, and technology-driven solutions. By aligning with global frameworks like the United Nations Sustainable Development Goals (SDGs), Greece has the opportunity to position itself as a global leader in sustainable tourism[1].

Published: December 2024

Environmental hygiene is an important issue that impacts health and quality of life. As a consequence, several measures are required to keep the environment clean, including fostering environmental hygiene habits at an early age. This study aims to describe the habituation of environmental hygiene in children with special needs. The type of research used is qualitative, which is analyzed descriptively, using direct observation and semi-structured interviews with open questions involving participants, namely educators and students five to six years old. The results of this study indicate that the habituation of environmental hygiene in children with special needs at Talented Kindergarten Semarang City runs well through various methods such as hygiene songs, making costumes made from used goods, and applying the concept of Zero Waste Life Style. Personal cleanliness and toilet training are examples of habituation, which is the process of doing something repeatedly until it becomes second nature. The existence of adequate facilities can support children in maintaining cleanliness. The involvement of teachers, parents, and professionals in children's therapy influences their growth and development, in order for these activities to foster self-reliance, accountability, and environmental consciousness.

Penelitian ini bertujuan untuk mengetahui persepsi masyarakat terhadap gadai lahan tambak di Gampong Rantau Panjang Kecamatan Ranau Selamat Kabupaten Aceh Timur, dan Untuk mengetahui praktek gadai lahan tambak di Gampong Rantau Panjang Bayeun Kecamatan Rantau Selamat Kabupaten Aceh Timur tinjauan perspektif ekonomi Islam. Untuk memperoleh jawaban peneliti menggunakan metode penelitian lapangan (field research) bersifat kualitatif. Hasil penelitian menunjukkan bahwa Presepsi Masyarakat terhadap praktik gadai lahan tambak yang dilaksanakan oleh masyarakat Gampong Rantau Panjang Kabupaten Aceh Timur yakni masyarakat merasa sangat terbantu karena adanya kebiasaan sistem gadai tersebut dikarenakan masyarakat tidak perlu repot mengurus gadai pada lembaga keuangan non bank yang tentunya prosesnya lebih terstuktur namun lama. Serta masyarakat melakukan sistem gadai sesuai kesepakatan kedua belah pihak sehingga masyarakat mengira hal itu menjadi boleh. Pelaksanaan praktik gadai lahan tambak yang dilaksanakan olehmasyarakat Gampong Rantau Panjang Kabupaten Aceh Timur belum sesuai dengan prinsip ekonomi Islam. Hal ini dikarenakan praktik gadai belum berlandaskan prinsip ekonomi Islam yaitu prinsip tauhid, keseimbangan, dan prinsip keadilan. Hal paling mendasar dan yang belum sesuai dengan prinsip ekonomi Islam ialah penambahan pokok hutang dan pemberian bagi hasil, walaupun dengan alasan untuk mendisiplinkan rahin dalam membayar hutangnya serta dilakukan dengan musyawarah itu dilarang dalam konsep ekonomi Islam karena setiap hutang yang menarik manfaat adalah riba.

Published: December 2024

Ideally, the legal system in Indonesia should guarantee justice and uphold human rights by protecting individuals from arbitrary arrests and fabricated cases. However, in reality, incidents of fabricated arrests, particularly in drug-related cases, continue to occur due to weak law enforcement and deficiencies within the system. This study aims to analyze the legal protection mechanisms for victims of fabricated arrests in drug cases from a human rights perspective, with the goal of achieving substantive justice. The methodology used is juridical-normative with a descriptive-analytical approach, utilizing primary and secondary data from literature review and analysis of relevant legal frameworks. The research findings indicate that although regulations exist that provide access to pretrial, compensation, and rehabilitation, their implementation is hindered by complicated procedures and lack of oversight over law enforcement authorities. The human rights perspective emphasizes the importance of physical, psychological, and social recovery for victims as part of efforts to achieve substantive justice.
