The objective of this study is to promote a more dynamic utilization of traditionally produced papers for artistic purposes. Specifically, the aim is to enhance the suitability of papers made through traditional methods using bast fibres from hemp, flax and linden plants for drawing and painting. To achieve this goal, a polysaccharide-based biopolymer material was employed during production. This biopolymer material was utilized in two ways: during the papermaking process and subsequently as a surface coating, where it was combined with starch. The visual quality and printability of the resulting papers, both produced and coated, were assessed. In our research, seaweed was utilized as a biopolymer to contribute to sustainability efforts. The inclusion of seaweed extract improved both the surface and barrier properties of the papers. By integrating bi-based seaweed into this study, we aim to introduce a new dimension to traditionally produced papers while promoting the principles of the circular economy. This preliminary study aims to lay the groundwork for future research by providing insights that enhance the quality of artistic papers in both traditional and industrial paper production contexts.

Criminal liability for violations of limits on freedom of speech in Latvia
Authors:   Chairman of the Criminal Law Policy Subcommittee of the Legal Commission of the Saeima of the Republic of Latvia, Judins Andrejs
Published: October 2024

Freedom of expression stands as a cornerstone of human rights. National and international law firmly establish the importance of freedom of expression. However, these same legal frameworks acknowledge limitations and potential legal consequences for exceeding those limitations. Provisions within criminal law serve as a clear reminder that this right is not absolute. In certain situations persons’ communication, publication and dissemination of information, incitement can pose a threat to protected interests, justifying the criminalization of such behaviour. As restrictions on freedom of expression constitute exceptions to the general principle guaranteeing free expression, analysing the reasons, criteria, and preconditions defining these limitations becomes essential. This article examines in detail the concept of freedom of expression and the admissibility of its restriction within the criminal justice system. Drawing on international and Latvian legal frameworks, it examines specific criminal code provisions that establish liability for violations. Additionally, it analyses the factors and circumstances that create a legal basis for such regulations. Keywords: freedom of expression; limits on freedom of speech; hate crimes.

Space ‘Tourism’: a Framework for Ensuring ‘Safe and Orderly Development’ Lessons Learnt from the U.S. and Aviation
Authors: Fox Sarah J.
Published: October 2024

In August 2023, following its successful mission, Virgin Galactic announced the intention to provide scheduled services into space. Yet, this paper sets out to present evidence to argue that, from an international (U.N.) perspective, there has been a lack of activity to establish safeguards and to ensure a fit for purpose governance and oversight mechanism is in place for this new and growing sector—space tourism. The research is undertaken by way of a comparison law/policy analysis which factors in key historic events across both aviation and space. The main focus is given to the developments and approach of the U.S.

The research finds that there remains a number of areas where clarity and advancement is needed both nationally (U.S.) and internationally; and that, without suitable governance and frameworks being established—safety is compromised, and equitability is not ensured for space tourists. It is advocated that there are clear lessons to be learnt from aviation developments and practices and that one solution would be a governance and oversight system as has been established by the International Civil Aviation Organization (ICAO).
horizonte valorativo em enunciados do gênero comentário online na defesa de um currículo homeschooling
Authors: Simões da Matta Ana Beatriz
Published: October 2024

Este trabalho, em diálogo com os pressupostos teórico-metodológicos da Perspectiva Dialógica da Linguagem, elaborada pelo Círculo de Bakhtin (Bakhtin, 1998, 2008, 2010; Medviédev, 2012; Volóchinov, 2017), destina-se a apresentar uma análise de enunciados do gênero comentário online a respeito do vídeo “Como montar um currículo para Homeschooling”, integrante do canal de Youtube intitulado “Canal Educalar”. O homeschooling, conceituado neste trabalho como escolarização doméstica (Penna, 2019; Traversinni; Lockmann, 2022), é um fenômeno educacional em que se reclama o direito de a família substituir, no espaço doméstico, a escolarização formal realizada comumente no espaço escolar. Tal fenômeno ganhou destaque por filiar-se a pressupostos neoliberais e (neo) conservadores, como a liberdade individual e a defesa da família tradicional, que foram mais legitimados ao longo do governo Bolsonaro (2018-2022). Desse modo, a análise dos 11 comentários, presentes no vídeo, pautou-se nos percursos metodológicos presentes em Volóchinov (2017), Rohling e Remenche (2016) e Rodrigues (2005), em que nos debruçamos a observar, primeiramente, a dimensão social do gênero comentário online para, posteriormente, analisarmos a dimensão verbal. A partir da análise dos comentários, percebeu-se a construção depreciativa do espaço escolar como um espaço prejudicial ao desenvolvimento do aluno, bem como a discursivização do homeschooling como possibilidade de proteção à diversidade social e a alunos com necessidades educacionais específicas. Mostrou-se presente, também, a vinculação aos projetos neoliberais e (neo) conservadores, como atitudes responsivas (Bakhtin, 2008) de valoração positiva a tais discursividades. Além disso, na materialidade imagética, houve o uso de emojis favoráveis à proposição do currículo no âmbito da escolarização doméstica, o que evidencia o potencial sociocomunicativo do gênero no acento valorativo do enunciado.
Introduction of Heat-Stable Carbetocin through a Public-Private Partnership Model in India: A Retrospective Study to Determine Feasibility and Its Optimal Use in Public Health Settings
Authors: Alwadhi Vaishali , Mishra Archana , Nagendra Anil , Bajpayee Devina , Joshi Naresh Chandra , Gupta Sachin , Kumar Harish
Published: October 2024

Background and Objective

The optimal use of oxytocin for preventing postpartum hemorrhage (PPH) faces challenges in many low-middle income countries (LMICs) owing to its storage and transportation prerequisites. We demonstrated Heat-Stable Carbetocin (HSC) for PPH prevention through an innovative Public-Private Partnership (PPP) model in 15 public health facilities of the Dewas District of Madhya Pradesh (MP) state in India. This study evaluates the feasibility and appropriate utilization of HSC in public health settings.

Methods

We analyzed facility-level data collected between August 2022 and July 2023 from selected 15 health facilities, where HSC was introduced. Prior to the introduction of HSC, all healthcare providers received training on Active Management of the Third Stage of Labor (AMTSL), use of HSC, and recording and reporting procedures. The supply of HSC in health facilities was ensured, and a robust mechanism was set up to monitor the progress.

Results

A total of 18,497 women were admitted for delivery in the 15 selected facilities. Uterotonic administration within one minute of delivery was almost universal (99.9%). No instance was recorded of using HSC either for induction of labor or management of PPH. In 636 cases (3.43%), HSC was not given for PPH prevention. Pearson’s chi-square test was conducted to assess the relationship between HSC usage and the health facility’s level. The HSC use was significantly higher in First Referral Unit (FRU) facilities compared to non-FRUs (p < 0.001). Moreover, the administration of HSC within one minute of delivery was also more prevalent in FRU facilities compared to non-FRUs (p < 0.001). The PPH incidence and case referral rates noted in this study were 0.7% and 16.7%, respectively, with no reported adverse drug events or deaths.

Conclusion and Global Health Implications

Our study suggests the safe and appropriate use of HSC within India’s public health system.

Authors: Tran Nguyen Toan , Mugerwa Kidza , Muwanguzi Sarah , Mwesigwa Richard , Wasswa Damien , Zeck Willibald , Seuc Armando , Schulte-Hillen Catrin
Published: October 2024

Background and Objective

Postpartum hemorrhage (PPH) remains a major concern in crisis-affected settings. There is a lack of strategies for implementing heat-stable carbetocin (HSC) and tranexamic acid (TXA) in humanitarian settings. This study aims to investigate the impact of a capacity-strengthening package on the utilization of uterotonics for PPH prevention, PPH detection, and utilization of TXA for PPH treatment in basic obstetric care clinics in humanitarian settings in Uganda.

Methods

A multi-stepped implementation research study was conducted, wherein six select facilities utilized an intervention package encompassing provider training, an online community of practice, and wall-displayed PPH algorithms. Facilities were conveniently assigned to the same study sequence: T1 (routine care), a transition period for training; T2 (package without HSC and TXA); T3 (package with HSC); and T4 (package with HSC and TXA). The primary outcomes assessed trends in prophylactic uterotonic use (including HSC), visual diagnosis of hemorrhage, and HSC and TXA use for hemorrhage treatment. Analysis followed an intention-to-treat approach, adjusting for cluster effect and baseline characteristics. Pan-African Clinical Trials Registry: PACTR202302476608339.

Results

From April 10, 2022, to April 4, 2023, 2299 women were recruited (T1: 643, T2: 570, T3: 580, T4: 506). Over 99% of all women received prophylactic uterotonics across the four phases, with oxytocin alone primarily used in T1 (93%) and T2 (92%) and HSC alone in T3 (74%) and T4 (54%) (T4–T1 95% CI: 47.8–61.0). Hemorrhage diagnosis ranged from 1% to 4%. For hemorrhage treatment, universal oxytocin use in T1 and T2 decreased in T3 and T4 after HSC introduction (T4–T1: 33%–100%; 95% CI: –100.0 to –30.9), and TXA use increased in T4 (T4–T1: 33%–0%; 95% CI: –2.4 to 69.1).

Conclusion and Global Health Implications

An intervention package to reinforce providers’ capacity to prevent and treat PPH can result in substantial HSC utilization and a moderate TXA adoption in cold-chain-challenged humanitarian settings. It could be scaled up with continuous capacity development and supportive supervision to mitigate confusion between existing and new medications, such as the decreased use of oxytocin for PPH treatment. Maintaining investments in cold-chain strengthening remains critical to ensure the quality of oxytocin.

Authors: P. C. P. Kumara  , Hewage Galagedarage Thushari Madhubhashini
Published: October 2024

This study investigated the building of the attribute agenda of an environmental crisis, taking the MV X-Press Pearl shipwreck incident as a case study. English weekend newspapers for a year since the incident were used for a content analysis to identify the information subsidies and their respective attribute agendas. An analysis framework was developed based on information subsidies and their respective attribute agendas. Results indicated that the governmental bodies unrelated to the environment were the most frequently cited sources, followed by experts and local non-governmental organizations/ industries. Conversely, the public was the least cited information source. Environmental damage was the most frequently emphasized attribute, followed by law and agreements and prevention. However, policy was the least reported attribute. Considering the correlation between information sources and attributes, the Marine Environmental Protection Authority highlighted the mitigation agenda, while non environmental related governmental bodies emphasized prevention agenda. Policymakers focused on getting compensation, while governmental bodies emphasized law and agreements and Experts prioritized on environmental damage.  The evidence for attribute agenda building was found further strengthening the agenda building hypothesis and information subsidies had their own attributes highlighted in media reports. The study delves into the practical implications of agenda building, which can influence media outlets. It suggests strategic communication planning, aligning coverage with objectives, and collaborating with environmental advocacy groups. This understanding informs decision-making, promotes balanced coverage, and enhances public engagement. It is important to additionally take into account the process used to establish the agenda in future research.

Published: October 2024

Метроритмические эксперименты в лирике И.Л. Сельвинского 1920х гг. взаимосвязаны как с эстетикой конструктивизма, так и с теорией тактового стиха, полемично развивавшихся в контексте утверждения декламационнотонической системы стихосложения и идейнохудожественных инноваций футуристов. Исследование структуры дольников, тактовиков, переходных форм, акцентного стиха в творчестве поэтаконструктивиста, выявившего в искусстве версификации музыкальные основы, позволяет говорить о Сельвинском как о виртуозе стиха .

Certain metric and rhythmical experiments in I.L. Selvinskys poems released in the 1920s correlate both with the aesthetics of constructivism and with the theory of tactbased verses. Both the concepts were polemically developing under the context of recitationtonic system of versification as well as conceptual and artistic innovations of the futurists. The structure of dolnics, tactbased verses, transitional forms, accentual verse analyzed on the bases of the constructivism poets works. The latter identified musical foundations in the versification art which proves Selvinsky to be a verse virtuoso .

Published: October 2024

Forklifts, as lifting and transportation equipment, play a crucial role in logistics. However, forklift operators often chase targets, pushing the forklift to perform at higher speeds. Operating a forklift at high speeds not only poses potential dangers to the working conditions but can also lead to a decrease in forklift performance. Operators do not ensure the forklift is running according to procedures due to a lack of supervision. In response to this issue, the author proposes an innovation in the form of a monitoring device capable of recording speed violations committed by operators. With the planned device, it is expected that forklift operators will exercise more caution and take greater responsibility when operating the forklift. The objective of this research is to reduce the likelihood of accidents and forklift damage due to improper use. The study produces a forklift design equipped with supporting components for the implementation of the device and a website as a monitoring platform for forklift operators and workers, providing real-time access to collected data. This system enhances operational safety in operating forklifts. The research significantly contributes to the development of safer and smarter forklift technology, aligning with strict demands for safety standards and risk management in industrial environments.
Design and Implementation of Wind Speed-Based Radar Antenna Safety System Prototype
Authors: Sumari Arwin Datumaya Wahyudi , Partono Rani , Funny Rindu Alriavindra
Published: October 2024

Air defense radar is a system that detects the presence of one or more air objects at a certain distance, altitude, and direction. One type of air defense radar used by the Indonesian National Armed Forces (TNI) is the Thomson TRS 2215D. An essential part of the radar is the rotating part of the radar antenna support called the antenna pivot. The rotation of the radar antenna must constantly be monitored and controlled for rotational stability at a speed of 6 Rotations per Minute (RPM) with a maximum wind speed of 120 km/h to prevent damage to the driving gear. Stormy weather with high wind speeds can cause the rotation speed of the radar antenna to be uncontrollable, which can cause damage. The solution offered in this study is to build a safety system that will lock the radar antenna automatically when the wind speed is detected to exceed tolerances and maintain the security of the radar antenna and its support system. The safety system was designed using an ESP32 Wi-Fi device equipped with an anemometer wind speed sensor, a Liquid Crystal Display (LCD) monitor, a Direct Current (DC) motor, and a Blynk Internet of Things (IoT) application. The test was conducted in a simulation using a multi-meter and oscilloscope measuring instrument. Testing the radar antenna's safety system prototype on a laboratory scale shows that the safety system can work as designed. The system can lock the radar antenna when the airflow is set at a speed of 54 km/h or 15 m/s, communication with the Blynk server works well, and the ESP32 device can transmit data at a maximum distance of 14 meters.

The large-scale implementation of analog switch-off for television broadcasting in Indonesia has led to blank spots in several regions. To address this issue, an optimal propagation model is needed. Proper selection and analysis of the channel model can enhance transmitter coverage, increase coverage percentage, improve energy efficiency, and boost field strength due to optimal transmit power. Previous studies have explored various DVB-T2 propagation models, notably the ITU-R P.1812-4 and Longley-Rice models, which are sophisticated and consider various environmental parameters, making them suitable for diverse broadcasting conditions. This research introduces a novel approach by specifically focusing on the urban context of Semarang City, Indonesia, to reduce blank spots by applying the ITU-R P.1812-4 and Longley-Rice propagation models. This study uniquely compares the two models to determine the most effective one for this urban area. Results indicate that the ITU-R P.1812-4 model provides a higher field strength value than the Longley-Rice model, with average field strengths of 108.3425 dBμV/m and 108.2325 dBμV/m, respectively. The difference in average field strength of 0.11 dBμV/m, despite having the same free space loss value of 100.9025 dB, indicates that one model has a slightly stronger signal. This stronger signal can improve coverage by reaching further distances and penetrating obstacles better. Additionally, a stronger signal means less power is needed to maintain the same coverage area, thus improving energy efficiency. This research not only offers empirical data specific to Semarang City but also provides insights that can guide future digital broadcasting optimizations in similar urban environments.
PID Controller with an Override Mode for a Wall-Following Robot with a Rotating Sensor Compartment
Authors: Sitompul Erwin , Rohmawan Elan , Silitonga Arthur , Bukhori Iksan
Published: October 2024

This paper presents the design of a wall-following robot (WFR) with a rotating sensor compartment to reduce the number of distance sensors used. Two infrared (IR) sensors were fitted in the compartment that rotates back and forth at 45°, producing four measurement values at each rotation cycle. The WFR was regulated using a novel control scheme of PID controller with an override mode. A discrete PID controller in position form was used to run the WFR to follow straight wall segments or walls turning left, while an override mode governed the WFR to follow walls turning right. The sampling time was set to 300 ms. The parameters of the PID controller were tuned using a trial-and-error method. The Mean Absolute Errors (MAE) was selected as the cost function. The WFR conducted twelve trial runs along a trial track with a length of 200 cm, consisting of one right turn and one left turn. The parameters that yielded the lowest MAE of 0.90 cm were used for further tests. Subsequently, a closed track for testing was constructed with a length of 845 cm, consisting of 7 right turns and 2 left turns. The WFR completed five test runs successfully, each elapsing the test track twice. The lowest MAE during the tests was 1.06 cm. The favorable performance of the proposed WFR strengthens future development efforts to equip the robot with more hardware to fulfill specific tasks and to put the completion time into optimization consideration.
Migration Effects cause Linear Response in Cyclic Voltammetry of Metal Anode Electrodeposition/Dissolution without Supporting Electrolyte: Calculations and Experiments on a Model Case
Authors: Yokoyama Yuko , Yamamoto Masahiro , Kano Kenji
Published: October 2024

Cyclic voltammetry of metal anode electrodeposition/dissolution often gives linear response in the absence of supporting electrolyte. For a one-electron redox model system without supporting electrolyte in which both redox species are soluble, and the oxidized one is zero-valent, finite different numerical calculations on the Nernst–Plank–Poisson equation have revealed that migration effects almost entirely counteract the overpotential to exhibit such linear responses in voltammetry. In the calculation the dumping Newton–Raphson method was used to avoid numerical divergence. The voltammetric response calculated on the model system was verified on a ferrocene-derivative redox system that yields a soluble zero-valent oxidative product. An approximate interpretation of the linearity was also proposed.

Oil Price Fluctuations, US Banks, and Macroprudential Policy
Authors: Gelain Paolo , Lorusso Marco
Published: October 2024

Using US micro-level data on banks, we document a negative effect of high oil prices on US banks' balance sheets, more negative for highly leveraged banks. We set and estimate a general equilibrium model with banking and oil sectors that rationalizes those findings through the financial accelerator mechanism. This mechanism amplifies the effect of oil price shocks, making them non-negligible drivers of the dynamics of US banks' intermediation activity and of the US real economy. Macroprudential policy, in the form of a countercyclical capital buffer, can meaningfully address oil price fluctuations and reduce the volatility they cause in the US economy.

Published: October 2024

Hyperglycemia in diabetes is associated with obesity and increases the production of free
radicals which is the beginning of the development of oxidative stress. This study aimed
to determine the effect of cowpea sprout yogurt (CowpeaS-Yo) on body mass index
(BMI) and malondialdehyde (MDA) levels in type-2 diabetes mellitus (T2DM) with obese
patients. This study used a pretest-posttest control group design, with 20 women with
T2DM with obesity, which was randomly divided into two groups of ten women in each
group. Group I was given CowpeaS-Yo, while group II was given a placebo as a control,
200 mL/day, for 2 months. Before and after the intervention, the subject's weight and
height were measured, and 1 mL of their blood sample was taken, to check their plasma
MDA levels. Data were analyzed using a paired sample t-test. After two months of
intervention, BMI decreased significantly from 28.53±2.27 to 24.56±2.55 kg/m2
(P =
0.002) in the group receiving CowpeaS-Yo, as well as decreased plasma MDA levels from
7.49±0.72 to 6.24±0.59 nmol/mL (P = 0.015) compared to the control group. In
conclusion, CowpeaS-Yo was able to control body weight and improve the antioxidant
status of T2DM in obese patients.

Authors: Dong Junchao , Lazaro Joan P.
Published: October 2024

This study aims to investigate the influence of social media on college choice among undergraduates majoring in Big Data Management and Application in China. The study attempts to reveal how information on social media platforms such as Weibo, WeChat, and Zhihu influences the cognition and choice process of prospective students. By employing an online quantitative survey questionnaire, data were collected from the 2022 and 2023 classes of new students majoring in Big Data Management and Application at Guilin University of Electronic Technology. The aim was to evaluate the role of social media in their college choice process and understand the features and information that most attract prospective students. Social media has become a key factor influencing the college choice decision-making of undergraduates majoring in Big Data Management and Application in China. Students tend to obtain school information through social media platforms and use this information as an important reference in their decision-making process. Higher education institutions should strengthen their social media information dissemination, providing accurate, timely, and attractive information. It is also necessary to ensure effective management of social media platforms, maintain a positive reputation for the school on social media, and increase the interest and trust of prospective students. Simultaneously, educational decision-makers should consider incorporating social media analysis into their recruitment strategies to better attract new student enrollment. This study provides a new perspective for understanding higher education choice behavior in the digital age, particularly by revealing the importance of social media in the educational decision-making process. This has important practical and theoretical implications for higher education institutions, policymakers, and social media platform operators.

It explores theoretical foundations and practical implementations and addresses challenges such as the need for specialized educator training, overcoming institutional resistance, and securing adequate resources. Advocating for empirical research and strategic cultural partnerships, the paper proposes a transformative approach to vocational education, aligning it with contemporary societal and labor market demands, and underscores the vital role of classical aesthetics in enriching vocational training and enhancing student outcomes.
A Study of the English Translation of Characteristic Cuisines of the Hexi Corridor from the Perspective of Multimodal Discourse Analysis
Authors: Luo Jing
Published: October 2024

Given the diversity of geographical and cultural backgrounds, it is difficult to find precise counterparts of many food-related vocabularies in the unique dietary culture of the Hexi Corridor in the target language, making it challenging to fully convey the essence of its local dietary culture in translation. To achieve the purpose of translation, the theory of multimodal discourse analysis provides an ideal translation approach through the language mode, image mode, sound mode, and the synergistic effect of multimodalities, which can accurately address the deficiencies in the translation of dietary culture. Through this research, it is not only possible to highlight the unique charm of the dietary culture of the Hexi Corridor but also to build a bridge for its international dissemination, promoting cross-border cultural exchanges and mutual understanding.

Semantic Foundation and Evolution Mechanism of the “好不X” (haobu X) Structure
Authors: Wang Qian , Zhou Qinwei , Zhang Di , Shi Jiajia , Cheng Siqian
Published: October 2024

In Chinese, the “好不X” (haobu X) structure expresses three types of meanings (negation, affirmation, and both affirmation-negation), where X exhibits differences in semantic symmetry. So far, no systematic explanatory theory has been proposed to account for these differences. Therefore, this paper presents and argues for an explanatory hypothesis that progresses through four stages: “很不X” (henbu X) => “好不X” (haobu X) (negation) => [ironic use] “好不X” (haobu X) (affirmation) => expansion and obstruction of affirmative “好不” (haobu). Specifically, (1) the basis of the negation “好不X” (haobu X) is attributed to “很不X” (henbu X), and the semantic asymmetry of X (excluding negative words) is explained using politeness principles, irony, and the semantic valence of negation results; (2) the ironic use of the negation “好不X” (haobu X) gives rise to the affirmation “好不X” (haobu X); (3) the grammaticalization and expansion of the positive meaning of “好不” (haobu) extend to X, which cannot appear in the negative meaning “好不__” structure (including words with opposite meanings and high polarity positive words). This explains the semantic symmetry of X in the positive meaning “好不X” (haobu X) structure; (4) when the affirmation “好不” (haobu) expands to the negation “好不X” (haobu X), it encounters both obstacles (X includes neutral and some positive words) and compatibility (X is some other positive words), thus explaining the semantic asymmetry of X in the affirmation-negation “好不X” (haobu X) (i.e., X is positive words).
