Background
We aimed to explore the differences in plasma biomarker levels between patients with familial cerebral cavernous malformations (FCCM) and their healthy first-degree relatives (FDRs) and between FCCM patients with and without severe chronic disease aggressiveness (CDA).
Methods
Magnetic resonance imaging (MRI) scanning and genetic testing was performed in patients with multiple CCMs and their FDRs. Sixty-seven plasma biomarkers were tested using a customised multiplex bead immunoassay kit. Univariate and multivariate unconditional logistic regression analyses were conducted to determine the associations between plasma factors and the risk of developing FCCM and severe CDA. Receiver operating characteristic (ROC) curves were generated for each independent risk factor.
Results
Plasma factors of 37 patients with FCCM and 37 FDRs were examined. Low CD31 (P < 0.001) and BDNF levels (P = 0.013) were independent risk factors for FCCM. The best model was achieved by combining the results of CD31 and BDNF (AUC = 0.845, sensitivity 0.838, specificity 0.784, cutoff score − 4.295) to distinguish patients with FCCM from healthy FDRs. Low serpin E1/PAI-1 (P = 0.011) and high ROBO4 levels (P = 0.013) were independent risk factors for severe CDA in patients with FCCM. The best model was achieved by combining the results of E1/PAI-1 and ROBO4 levels (AUC = 0.913, sensitivity 1.000, specificity 0.760, cutoff score − 0.525) to identify patients with FCCM and severe CDA.
Conclusions
The plasma concentrations of CD31 and BDNF seem to be lower in patients with FCCM than in their healthy FDRs. Low serpin E1/PAI-1 and high ROBO4 concentrations may be correlated with high lesion burden and risk of recurrent bleeding.

Objective To analyse and summarise the clinical characteristics, diagnosis, treatment and prognostic features of abdominal wall endometriosis.
Methods A retrospective analysis of patients with abdominal wall endometriosis who attended Changzhou Second Hospital of Nanjing Medical University from January 2013 to December 2022 was performed. They were grouped according to the depth of infiltration of the lesion and the direction of incision, and the differences between the groups were compared.
Results A total of 228 patients with abdominal wall endometriosis were included in this study, including 210 cases with a history of abdominal transverse incision surgery, 16 cases with a history of vertical incision surgery, 1 case with a history of uterine fibroids surgery, 1 case with primary abdominal endometriosis, and 178 cases with the primary symptom of cyclic pain. They were classified as solitary and complex according to the number of lesions. Both were statistically significant for BMI, number of caesarean sections, operative time, bleeding and postoperative hospital stay (p<0.05). According to the depth of infiltration, they were divided into fascial, rectus abdominis and peritoneal types. There were differences between the three in latency time, CA125, maximum diameter of the lesion, operation time, bleeding and postoperative hospital stay (p<0.05). The direction of incision for caesarean section had no significant effect on the development of endometriosis in the abdominal wall or whether the lesions were multiple (p>0.05). On imaging, magnetic resonance imaging was more accurate for lesion typing.
Conclusion AWE should be diagnosed early and treated surgically. The clinical manifestations of the same type are different, and CA125 test and abdominal wall ultrasound can be used preoperatively to determine lesion typing. Nuclear magnetic resonance (NMR) may be used to improve preoperative preparation for difficult diagnosis or staging.

Published: July 2024

Light plays a crucial role in several physiological processes in plants, ranging from photosynthesis to the biosynthesis of secondary metabolites such as carotenoids. The emergence of Light-Emitting Diode (LED) technology, has granted researchers unprecedented control over light quality and intensity, enabling detailed research into its effects on plant growth, development, flowering, and secondary metabolite accumulation, such as carotenoids. Carotenoids, vital pigments in plant physiology, serve for pollinator attraction, photoprotective molecules, and precursors for vitamin A biosynthesis. Carrots (Daucus carota) known for their high carotenoid levels provide an excellent model for studying the impact of light on carotenoid biosynthesis and taproot development. In a comprehensive study exploring the effects of different light conditions on carrot storage root development and carotenoid content, we employed three lighting regimes: fluorescent light (F) with a high green light content, LED light with a spectrum enriched in blue and red wavelengths (NS12), and LED light with a higher content in Red and Far-Red light and with the highest light intensity (AP67). Our findings revealed that NS12 and AP67 induce an early development of secondary root growth due to carrot storage roots exhibiting wider and heavier storage roots compared to those grown under F light. Together, these findings correlate with an enhancement in carbon fixation, as evidenced by the improved levels of sucrose and starch under LED lighting. Despite these differences, there were no observable variations in carotenoid content. However, there was an induction of DcPSY1 and DcPSY2 expression in 8 weeks old storage roots of plants grown under LED lights. Taken together, the quality and intensity of aboveground light in which the carrot is grown significantly affects the development of the storage root but not on carotenoid content. These findings underscore the profound influence of light quality on underground organs and highlight the potential of LED technology to optimize crop production by promoting favourable traits in storage organs.
Far Out! – the effects of far-red light on Cannabis
Authors: Peterswald Tyson J. , Mieog Jos C. , Kretzschmar Tobias , Purdy Sarah J.
Published: July 2024

Far-red (FR) light elicits two distinct processes in plants. First, a shade avoidance response which is triggered when the ratio of red to FR (R:RF) declines. Second, the Emerson effect in which the efficiency of photosynthesis is improved by the combination of FR and R light. We investigated whether we could harness these phenomena in medicinal Cannabis to improve yields so that the duration of the photoperiod could be reduced to 10 hours (“10L”) whilst returning similar or improved yields compared to a 12 hour photoperiod (“12L”). The THC concentrations were elevated in both high THC varieties by the different FR treatments. In Hindu Kush the concentration of THC was elevated by the addition of 4 hours of total FR (“10L_2_2D”), and in Northern Lights total cannabinoid yields were increased by nearly 70% over the 12L control by the addition of 2 hours of FR in darkness after 10 hours of light (“10L_2D”). Our results show a strong yield and quality advantage in high THC lines treated with end-of-day FR treatments. Furthermore, a lighting schedule of 10L_2D instead of 12L would result in a saving of 5.5% in power usage and resultant emissions.

Authors: Wang Liang , Li Yilin , Zuo Lina
Published: July 2024

The rapid growth of IoT devices and the increasing demand for device interaction between different network partitions have significantly pressured IoT device management. To realize cross-domain trust integration between different partitioned devices, trust management becomes the key technology to realize cross-domain communication. However, trust management heavily relies on third-party entities, posing centralized risks. Therefore, we propose an IoT device trust management system based on federated learning and blockchain. By utilizing federated learning to assess device reputation ratings while safeguarding their privacy, the system stores reputation assessment results on the blockchain for authenticity and accuracy. The system’s decentralization is achieved using blockchain instead of a central server in federated learning. Additionally, we introduce a weighted aggre-gation model based on device attributes to obtain a more precise global model through weighted aggregation of local models in federated learning. Experimental results using a simulated dataset reflecting device characteristics demonstrate a device evaluation accuracy of 90.2%, validating the system’s effectiveness and feasibility.

Published: July 2024

Salt-tolerant bacteria associated with halophytes enhance plant resistance to environmental stress and promote plant growth through their metabolic activities. The current study explored the diversity and potential of bacteria associated with three halophytes from the salt-affected land of Wujiaqu, Xinjiang, China. The cultivable bactria were isolated from Salicornia europaea L., Kalidium foliatum (Pall.) Moq., and Suaeda aralocaspica, by using the culture-dependent method. The isolated bacteria were classified based on the differences between their 16S rRNA gene sequences and screened for plant growth-promoting traits. Our findings showed that the bacteria isolated from selected plants’ parts (roots and shoots) and soil (rhizosphere and bulk) belonged to 567 strains, four phyla, six classes, 25 orders, 36 families, and 66 genera. This study revealed that the tested strains could possess one or more plant beneficial traits. Among them, 20 strains representing Bacillus, Streptomyces, Isoptericola, and Nocardiopsis species exhibited several plant growth-promoting activities in vitro, including phosphate-solubilization, nitrogen fixation, siderophore production, cell wall degrading enzymes such as protease, and cellulase. Our findings demonstrated that halophytes are a source of plant-beneficial bacteria, which may adapt to various conditions and enhance plant development and fitness in challenging environmental situations.

Authors: Yang Tianjian , Wang Xing , Cheng Siyi , Chen You , Zhang Xi
Published: July 2024

Cooperative jamming effectiveness evaluation is a key component in completing the cooperative jamming OODA loop. For the problem of evaluating the effectiveness of cooperative jamming to group network radar by formation aircraft, a cooperative jamming effectiveness evaluation method based on Improved Particle Swarm Optimization- Extreme Learning Machine (IPSO-ELM) is proposed. Firstly, based on the working parameters of the group network radar and the information fusion rules, the cooperative jamming effectiveness evaluation function is established. On this basis, the cooperative jamming decision schemes and their corresponding cooperative jamming effectiveness values are solved at different locations in the target space, and the results are detected as outliers using box plots, thus constructing sample data for cooperative jamming effectiveness evaluation. Subsequently, a neural network based on Extreme Learning Machine (ELM) methodology is developed, with its initial weights and biases fine-tuned through an improved particle swarm optimization, which is termed IPSO-ELM. This optimization aims to boost the model’s predictive precision. Finally, the IPSO-ELM algorithm is subjected to rigorous assessment via simulation, confirming its performance of accuracy and efficiency. From the simulation results, the advanced performance of the IPSO-ELM algorithm, specifically in the context of assessing the effectiveness of cooperative jamming is verified.

Published: July 2024

The impact of climate change and urbanization has increased the risk of flooding. During the UN Climate Change Conference 28 (COP 28), an agreement was reached to establish "The Loss and Damage Fund" with the specific purpose of providing assistance to low-income countries impacted by climate change. However, allocating the resources required for post-flood reconstruction and reimbursement is a challenging task due to the limited availability of data and the absence of a comprehensive tool. Here, we propose a novel resource allocation framework based on remote sensing and geospatial data, such as buildings and population, near the flood peak. The quantification of resource distribution utilizes an exposure index for each municipality, which interacts with various drivers, including flood hazard drivers, buildings exposure, and population exposure. The proposed framework assesses the flood map using images derived from pre- and post-flood Sentinel-1 Synthetic Aperture Radar (SAR) data for flood extent and Sentinel-2 optical images for ground truth. To demonstrate the effectiveness of this framework, an analysis was conducted on the flood that occurred in the Thessaly region of Greece in September 2023. The analysis revealed that the municipality of Palamas has the highest need for resource allocation, with an exposure index rating of 6/6. This framework can be used by any government for rapid decision-making and to expedite post-flood recovery.

Authors: Smits Geert H.J.M. , Bots Michiel L. , Hollander Monika , Doorn Sander
Published: July 2024

Background
The impact of long-term, nurse-led, integrated cardiovascular risk management in primary care on cardiovascular disease incidence has not been previously investigated.
Methods
We compared cardiovascular disease incidence between 2013 and 2019 in 16,723 high-risk patients without established cardiovascular disease or diabetes receiving integrated cardiovascular risk management and extensive care group support (PoZoB) with 34,072 similar patients receiving a mixture of usual care and integrated care without any support (JGPN). In both patient groups, we estimated the incidence of acute myocardial infarction, transient ischemic attack, stroke, peripheral artery disease and abdominal aortic aneurysm.
Results
The incidence (per 1000 person-years) of a first event for patients aged 45 to 84 years in PoZoB was 17.5 [95% CI 16.2–18.9] for men and 13.6 [12.6–14.7] for women. The corresponding JGPN results were 22.2 [21.1–23.3] for men and 15.8 [15.0-16.7] for women. The event-specific incidence rates (PoZoB versus JGPN) for acute myocardial infarction were 3.7 vs 6.1 (men) and 2.0 vs 2.4 (women); those for transient ischemic attack were 4.5 vs 5.3 (men) and 4.6 vs 4.5 (women); those for stroke were 5.0 vs 6.1 (men) and 3.8 vs 5.3 (women); those for peripheral artery disease were 2.6 vs 3.0 (men) and 2.0 vs 2.0 (women); and those for abdominal aortic aneurysm were 2.3 vs 1.9 (men) and 1.0 vs 0.8 (women).
Conclusion
The results are compatible with a lower incidence of cardiovascular disease in women and men exposed to long-term integrated cardiovascular risk management. The magnitude of the relation could not be assessed due to unsolvable incomparability between the cohorts due to the nature of routine data collection in primary care.
Efficient positioning of QTL and Secondary Limit thresholds in a clinical trial risk-based monitoring
Authors: Shnaydman Vladimir
Published: July 2024

In the high-stakes world of clinical trials, where a company's multimillion-dollar drug development investment is at risk, the increasing complexity of these trials only compounds the challenges. Therefore, the development of a robust risk mitigation strategy, as a crucial component of comprehensive risk planning, is not just important but essential for effective drug development, particularly in the RBQM ecosystem. This emphasis on the urgency and significance of risk mitigation strategy can help the audience understand the gravity of the topic. The paper introduces a novel framework for deriving an efficient risk mitigation strategy at the planning stage of a clinical trial and establishing operational rules (thresholds). This approach combines optimization and simulation models, offering a fresh perspective on risk management in clinical trials. The optimization model aims to derive an efficient contingency budget and allocate limited mitigation resources across mitigated risks. The simulation model aims to efficiently position the QTL/KRI and Secondary Limit thresholds for each risk to be aligned with risk assessment and contingency resources. A compelling case study vividly illustrates the proposed technique's practical application and effectiveness. This real-world example demonstrates the framework's potential and instills confidence in its successful implementation, reassuring the audience of its practicality and usefulness.

Published: July 2024

Background: Organic anion-transporting polypeptides (OATPs) are responsible for the cellular uptake of a broad range of endogenous compounds and xenobiotics in multiple tissues. The aim of our study was to determine whether variations in OATP1B1 and OATP1B3 affect the side effects experienced by hepatitis C patients treated with direct-acting antivirals (DAAs).
Methods: This study included 199 hepatitis C patients treated with DAAs. ledipasvir (LDV)/sofosbuvir (SOF) or ombitasvir (OBV)/paritaprevir (PTV)/ritonavir (RTV)+/-dasabuvir (DSV) (PrOD) and 162 control individuals without hepatitis C. Treatment-related side effects were recorded. The OATP1B1 gene variations c.388A>G and c.521T>C and the OATP1B3 gene variations c.334T>G and c.699G>A were analyzed via the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.
Results: Side effects were observed in 53 (26.6%) of 199 hepatitis C patients. There were skin lesions in 19 patients (9.5%), fatigue in 18 patients (9%), pruritus in 11 patients (5.5%), and nausea in 5 patients (2.5%). There was a significant relationship between the c.334T>G variant and side effects (p=0.001 for all). A significant relationship was found between the OATP1B1 c.521T/c.388A allele and between the OATP1B3 c.699A/c.334T allele and side effects (p=0.010, p=0.042, respectively). The frequency distribution of the c.334T>G variant was in Hardy–Weinberg equilibrium. The frequencies of the patient group and the control group were 65.3% and 63%, respectively.
Conclusion: We found a relationship between the c.334T>G variant in OATP1B3 and DAA-related side effects in hepatitis C patients.

On the Question of the Trade Policy Imperatives of the Zemstvo Liberal Fronde of Northern Ukraine (60–80s of ХІХ cent.)
Authors: Kotelnytskyi Nazar
Published: July 2024

The investigation is devoted to finding out the imperatives of the trade policy of the Zemstvo Liberal Party of Northern Ukraine in the 60-80s of the 19th century. The author came to the conclusion that trade policy issues occupied not the last place in the economic program of the Zemstvo liberal movement in the north of Left Bank Ukraine in the 60-80s of the 19th century and were an organic part of the social doctrine of the specified trend in the liberation movement in the Russian Empire. At the level of city self-government, liberal citizens initiated the elimination of taxation of the trade system in order to avoid the processes of cartelization of the industry and to stimulate healthy competition between producers of products, both in terms of quality and at the level of price parameters. In order to destroy corruption and monopolies in the trade sphere, the representatives of the liberal opposition insisted on diversifying the service market, by granting the right to engage in relevant business to everyone, not only interested representatives of the region's Jewish commerce. In the field of public trade and commerce, Zemstvo progressives took a distinctly flexible economic position, trying to eliminate the ground for the emergence of any financial speculation and to maximize the portfolio of commercial offers on the market. In the context of the conservative clerical policy of the Russian autocracy, members of the opposition liberal front of the Northern Left Bank defended the right of representatives of the trade system to hold traditional fairs and bazaars on a regular basis for the purpose of neutralizing the threat of breaking economic ties between the cities and the province and avoiding the loss of the market for products which could lead to an increase in prices for socially important and sensitive groups of goods. Representatives of Zemstvo liberalism in northern Ukraine defended the idea of the need to transfer the area of trade to municipal or state ownership, which would allow, from their point of view, to control pricing procedures.
The Sorbian National Movement in the Struggle for Independence (1918-1919)
Authors: Yukovskyi Vladyslav
Published: July 2024

The Lusatian Sorbs, also known as Sorbs or Lusatians, are a small West Slavic ethnic group residing in the eastern part of modern Germany within the territories of Brandenburg and Saxony, around the cities of Bautzen and Cottbus, in the historical-geographical region known as Lusatia. Since the Middle Ages, Lusatia has been divided into southern and northern parts known as Upper and Lower Lusatia, and as a result, the small-sized ethnic group – approximately 80 thousand individuals – is divided into two sub-ethnic groups. The article describes the evolution of views and actions of Sorbian-Lusatian enlighteners, intellectuals, and political figures in their attempt to achieve the independence of Lusatian Serbia during the period from November 1918 to September 1919. In particular, it highlights the role of the Sorbian enlightening society "Domowina" and the activities of public figures Arnošt Bart and Adolf Černý in the Sorbian-Lusatian political movement. Drawing on the works of researchers in the history and culture of the Sorbian-Lusatian people, the article reveals the reasons that prompted Lusatian politicians to speak about independence, their relations with Czechoslovakia, and the consequences of the political struggle for statehood.

Metaverse as a means for branding: a new approach to communication aesthetics
Authors: Radiontseva E. S.
Published: July 2024

Digital technologies are changing the landscape of brands communication with consumers. The relevance of studying metaverses as a means communication is determined by the growing popularity of this digital media. The object of study of this article is metaverse, an important component of which is the new aesthetics in the formation of a dialogue between the brand and the consumer. The subject is forms and methods of aesthetic communication. The purpose of the article is to identify possible formats for the interaction of brands with metaverses that demonstrate unlimited possibilities in new aesthetics. The theoretical aspects of the research are represented as the methods of entry into metaverses. To analyze the empirical base, the author relies on a methodology that identifies different aspects in the aesthetics of brand communication through metaverses. The author’s research was carried out on the basis of the Medialogy media monitoring system and represents the data for two years: 60 communication campaigns reflected in 12,459 media texts of mass media and social media of different typological segments. Despite the lack of mass character in the promotion of such projects, the author believes that there is enormous potential in the format of interaction between brands and metaverses: the number of such campaigns is growing, they leave a ‘digital trace’, but do not always fit into the format of professional competitions or fall into focus of media attention. The author dwells in detail on the analysis of the case of the winner of “The Newsbreak – 2022” competition (Russia) and a random case of the Samsung brand, which is close in concept to the winner, but did not participate in the competition. The author demonstrates its potential for media coverage and social media. The results of the study show that brands’ interest in metaverses as a means for promotion will grow as it allows them to reveal brand aesthetics and create a new type of immersive relationship with audiences.

Changes in rice fields are an important phenomenon that affects the sustainability of agriculture and the environment. This study aims to analyze the pattern of changes in rice fields in Makroman Village, using a Geographic Information System (GIS) approach. The method used is spatial analysis which involves such as spatial data creation, spatial data conversion, spatial data clustering, and mathematical calculation of spatial data. The spatial data used in this study include Ikonos Satellite Images of Makroman Village in 2011 and UAV Aerial Photos of Makroman Village in 2019. The results showed that the area of rice fields in Makroman Village increased from 96.196 ha to 129.343 ha in 2011-2019. Spatially, the increase occurred due to the presence of new rice fields and existing rice fields that did not decrease in number. Shrubs become land uses that have the potential to be converted in rice field extensification activities. GIS application is a method that can be used to answer the problems in this study to the level of detail, but some things that need to be considered in the application of this method are the quality of spatial data, especially remote sensing data used.

The community in Central Bangka Regency carried out an increase in illegal mining in 2021, which could potentially threaten the loss of strategic natural resources. Rocking table miners in Central Bangka Regency produce zircon sand, tin sand, monazite, ilmenite, and tailings, which are potential natural resources containing rare earth metal elements. This research aims to analyze the radioactive content of the minerals zircon sand, tin sand, monazite, ilmenite, and tailings as a threat to human health. The research showed that monazite samples from all villages still had a lot of rare earth metals in them, like yttrium (Y), lanthanum (La), cerium (Ce), samarium (Sm), neodymium (Nd), and gadolinium (Gd). The test results showed that monazite had the highest average concentrations of Rare Earth Elements (REEs), with values of 10.27±3% for La, 12.15±3% for Ce, 24.40±3% for Sm, 7.37±3% for Nd, and 0.69±3% for Gd. For tin samples, the average (Ce) was 2.79±3%, zircon samples had an average (Ce) of 4.33±3%, and (Nd) 1.04±3%. In the ilmenite samples, the average value (Y) was 6.64 ± 3%. Monazite has the most rare earth metal elements, but it has a very low selling price. Monazite plays a crucial role in safeguarding and preventing the loss of strategic natural resources and health threats. It provides policy advice to related institutions through various roles and functions, including investigation, early prevention, and forecasting of these threats.

Desde la COVID-19, la integración de herramientas y competencias digitales en la enseñanza superior ya es una realidad en todos los países. El objetivo de este estudio es analizar la percepción del profesorado (n = 88) y del alumnado (n = 487) de los Grados en Educación Infantil y Primaria y Máster de formación del profesorado de una universidad pública de Madrid acerca de la evolución de su competencia digital, en general, y de las diferentes áreas competenciales, tanto antes como durante la enseñanza remota de emergencia. Para ello, nos apoyamos en el conocido Marco Común de Competencia Digital Docente del Instituto Nacional de Tecnologías Educativas y de Formación del Profesorado (INTEF). Desde una metodología cuantitativa y un cuestionario ad hoc validado por expertos se ha realizado un análisis descriptivo, correlacional e inferencial de las variables. Los resultados evidencian en los dos perfiles la disposición de recursos digitales suficientes para enfrentarse a esta modalidad, un aumento significativo de la autopercepción de esta competencia, destacando mayor desarrollo en las áreas: Comunicación y Colaboración, Creación de contenidos digitales y Seguridad. También muestran descontento hacia la modalidad virtual por la excesiva carga de trabajo y la formación continua requerida. El estudio ayuda a replantear los planes de estudio del futuro docente y los planes de formación del profesorado universitario sobre la necesaria competencia digital en la actualidad.
Inspirando Designers: Mapeamento inspirador da Inclusão pelo Design (MID)
Authors: Trigueiros Paula
Published: July 2024

Promover a inclusão é um objetivo transversal, associado a vários desafios globais da atualidade. Embora seja cada vez mais reconhecido pela sociedade, o talento e o potencial criativo dos designers é pouco canalizado para soluções inclusivas e na concretização do papel social do Design. Neste trabalho defende-se a disseminação de estratégias pedagógicas usadas no contexto do Design Inclusivo no sentido de promover a mudança de atitudes e a formação de melhores designers. O trabalho começa por narrar cinco estórias da experiência da autora, construídas com base em testemunhos e análise documental de outras boas práticas de inclusão pelo Design. Estas abordam respetivamente, cinco tópicos: Argumentos, Pedagogia, Interdisciplinaridade, Parcerias e Disseminação. As inquietações expostas na problemática são discutidas e corroboradas por alguns autores consultados na revisão de literatura: verificam-se barreiras à utilização de informação e no uso de algumas ferramentas criadas no contexto do Design Inclusivo e questiona-se a sua adequação ao perfil dos designers e, em particular, dos estudantes. Estas reflexões conduziram à proposta de um referencial para Mapeamento inspirador da Inclusão pelo Design (MID): uma ferramenta organizada em dois eixos que suporta o mapeamento de soluções e oportunidades considerando variáveis que promovam a inclusão desde início do processo de Design. Pensada para o contexto do ensino, esta proposta ambiciona inspirar e promover a comunicação entre pessoas de várias áreas e níveis de formação, de modo prático, dinâmico e visual – ou seja, pretende ser ela própria uma ferramenta mais inclusiva.
An Application of the Kaldor-Dixon-Thirlwall Model for Regional Economic Growth in Mexico

Published: July 2024

This paper analyzes the links between exports and regional economic growth in Mexico. The Kaldor-Dixon-Thirlwall theoretical model and the econometric methodology of Durbin spatial panel models are used, which were estimated for the periods 2008-2019 and 2008-2023. The econometric results show, among other findings, that the relationship between regional growth and state export growth is null and non-significant, while trade openness and its absolute growth are positive and significant. The weak relationship between exports and regional growth implies that industrial policy proposals other than traditional ones should be promoted. A limitation of this study is the absence of data on regional imports, which could have enabled a more comprehensive examination of theoretical frameworks. Nonetheless, the study's significance lies in highlighting the limited role of the export sector in driving regional growth in Mexico, attributed to the weakening of national productive links.

High strength and good conductivity are both critical parameters for copper-based alloys for electrical and other technological applications. This study is aimed to produce copper alloys and metal matrix composites (MMCs) with enhanced physical properties. Cu-Ti-Ni ternary alloys and MMCs samples were sintered at 600 to 700°C using spark plasma sintering (SPS), with a heating rate of 100°C/minutes, uniaxial pressure of 50 MPa, and a holding time of 10 minutes. Scanning electron microscopy (FE-SEM) was used to examine the microstructure, while the relative densities of the composites were obtained via the Archimedes Principle method. A four-point probe and differential thermal analyzer (DTA) obtained electrical resistivity and thermal properties. The results indicated that the sample density nominally increases with sintering temperature but decreases with aluminium nitride additions. The electrical conductivity increases with the sintering temperature and AlN nanoparticle content. Distinct phase changes were observed from the DTA, occurring with the addition of AlN.

Farmers' Terms of Trade is an essential variable for measuring welfare and is also affected by other factors, such as inflation and rice prices. Therefore, this study aimed to investigate the interplay among inflation, rice prices, and farmers' Terms of Trade in food crop farming in Central Java Province, in short and long term using a dynamic model. A quantitative method employing Autoregressive distributed lags (ARDL) model was used with monthly data from January 2018 to March 2023. The results showed that rice prices and inflation partially had a significant and positive influence on farmers’ Terms of Trade in long term. According to short term estimation, the dependent variable was significantly and positively influenced by farmers' Terms of Trade from the previous 1-2 months. Inflation rate was also shown to have a positive influence on the variable in short term. In addition, rice prices had a positive and significant impact in the previous 3 months, but had no significant influence in recent months. Based on the results, inflation could positively influence farmers’ Terms of Trade in short and long term. However, the recent rice prices had no impact due to the requirement of time lags. The assessment findings showed that recent rice prices could significantly increase farmers’ Terms of Trade in the next 3 months and long term period.

Tourism sector plays an important role in increasing the country's foreign exchange and promoting the creation of jobs to improve the economy. In this context, community organizations manage tourism sites, and the leaders are tasked with directing members to achieve common objectives. An important tourist site is Open Pit Nam Salu Geosite and participation is relatively low since people depend on illegal tin mining. Village government and community organizations are less assertive in overcoming the problems. Therefore, this research aims to analyze development model for increasing participation in tourism management of Open Pit Nam Salu Geosite in Senyubuk Village, Kelapa Kampit District. The location determination was carried out purposively, with 87 respondents selected by cluster sampling method through the PLS test. The results showed an indirect effect of community capital and leadership on participation through group roles. Meanwhile, leadership promoted participation since community capital and group roles served as mediator variables. Pokdarwis and village government were also strengthened in organizing community to maximize the potential of capital in the region and mobilize BAPOPNAS group to manage tourism daily.
