Research on Political and Economic Trends before and after Brexit: Take the Position of the Pound and Changes in the Exchange Rate as an Example
Authors: Zhu Yumeng
Published: June 2024

As a former overlord of the world, Britain has always played an important role in Europe. In the process of multi-polarization, the European Union has become the general trend and gradually moved towards a whole. Since the 21st century, European integration has entered a period of decline. Due to the historical tradition of independence and the practical reasons for political and economic differences, Britain chose to leave the European Union, which further aggravated the crisis of the European Union. It is of great significance to deeply study the reasons for Brexit, the changing trend of Britain’s political and economic status, and the political and economic impact of Brexit on Britain, the European Union, and even the world. Therefore, this paper will study the economic trend of the UK before and after Brexit from the perspective of the status of the pound and the change in the exchange rate and analyze the world status and political influence of the UK before and after Brexit from the perspective of international relations. At the same time, this paper will use literature analysis to search and read relevant materials and literature, use economic newspapers and other specific data to support personal views, analyze economic changes, and then draw research results. In the future, the British economy will face greater challenges, and in the political aspect, it is likely to further move closer to the United States and strengthen economic and security cooperation with English-speaking countries such as North America, Australia, and South Asia.
A novel Spatial Econometric Model Approach to Analyze the Association Between Digital Economy and Consumption Upgrading
Authors: Li Jiaqian
Published: June 2024

This paper examines the association between the digital economy and consumption upgrading in five coastal cities in China from 2016 to 2020, using a spatial econometric model. The results indicate that consumption upgrading exhibits significant spatial agglomeration. The development of the digital economy can facilitate the level of consumption upgrading and has a positive spilling over effect on the level of consumption upgrading in neighboring regions, thereby narrowing the spatial differences in consumption upgrading between regions. The mediation effect suggests that the digital economy can promote industrial upgrading, which in turn promotes consumption upgrading. To promote sustainable consumption, China should continue to develop the digital economy, upgrade traditional industries, and coordinate digital economy development across all regions.
The Impact of China-Japan Economic Cooperation on Regional Security: A Case Study of the Japanese Official Development Assistance (ODA) to China
Authors: Hou Yansong , Luosang Zhaxi , Wang Zhe
Published: June 2024

The issuance of the China-Japan Joint Declaration in 1972 marked the beginning of reconciliation and exchanges between the two countries, and since then Sino-Japanese relations have continued to advance in twists and turns. The issue of territorial sovereignty, historical understanding and changes in relative strength in the political field of the two countries have all hindered the development of bilateral relations. However, the implementation of the China-Japan Joint Declaration has provided many new possibilities for exchanges and cooperation between the two countries, and the continuous development of economic relations between the two countries has promoted the improvement of bilateral relations and regional security. This paper finds that the Japanese official development assistance (ODA) to China initially brought China and Japan closer and promoted the improvement of regional security, but later due to the emergence of many problems, Japan's ODA policy was adjusted, making the role of the ODA in promoting bilateral relations and regional security disappear. Therefore, economic cooperation should not be affected by the issue of political mutual trust, and economic cooperation without political interference could be the best way to improve Sino-Japanese relations today.
Evaluating ChatGPT: Strengths and Limitations in NLP Problem Solving
Authors: Wu Yanyi
Published: June 2024

This paper critically analyzes ChatGPT’s problem-solving performance on a range of natural language processing (NLP) tasks. Using a comparative methodology, it compares ChatGPT’s performance with that of its predecessor, GPT-3.5, in seven different domains: summarization, named entity recognition, arithmetic, natural language inference, symbolic and logical reasoning, question answering, conversation, and arithmetic. The process entails a methodical assessment highlighting ChatGPT’s replies’ quantitative and qualitative elements. The findings show that although ChatGPT performs very well on math and question-answering tasks, it struggles with summarization and commonsense reasoning. The conversation sheds light on the subtleties of these findings while considering the applications and development of AI. The article concludes that although ChatGPT is a significant progress in natural language processing, its uneven problem-solving performance highlights the need for continued development and optimization of artificial intelligence models. This study aids in understanding the state and promise of AI-driven language models in challenging problem-solving situations.

Research on Multi-Beam Sounding Based on Local Optimal Model
Authors: Song Xinrui , Song Zhenyu , Chai Zheng
Published: June 2024

Multi-beam sounding technology can provide higher spatial resolution than single-beam sounding by transmitting fan-shaped acoustic signals from the transducer of a survey ship along the normal plane of the survey line to measure the sea depth. It is of great significance to study the line design scheme of multi-beam sounding for uneven seabed topography to improve the efficiency of underwater terrain mapping. This paper mainly studies the optimization of multi-beam sounding line under ideal slope. Firstly, a single angle model of ideal slope is established, and the flat seabed overlap ratio formula is extended to slope seabed to calculate the coverage width of beam sounding. Secondly, an angle model of ideal slope is established to calculate the corresponding coverage width under different positions of the slope sea area. Finally, the optimal routing model of ideal slope is established. The design scheme of the local optimal survey line is obtained through comprehensive analysis. In engineering practice, the optimal routing of real terrain can be solved by using the ideal slope optimal routing model through the idea of plane approximation, which provides a new idea for the optimal route selection of underwater terrain mapping.
New Energy Demonstration City Policy and Green Innovation of New Energy Enterprises——A Quasi-Natural Experiment Based on Green Patent Applications of Listed Companies in China
Authors: Jiang Yankai
Published: June 2024

The innovation and development of the new energy industry is crucial to guaranteeing China's energy security, promoting high-quality economic development and alleviating the global climate crisis. New Energy Demonstration City Policy (NEDC) is one of the important policies to promote the development of the new energy industry in China. Academic research on their green innovation effect on new energy enterprises and the explanation of their influence mechanism still needs to be deepened. This paper utilizes panel data from listed companies in China spanning from 2011 to 2019 and employs the triple difference method to empirically investigate the impact of NEDC on the green innovation of new energy enterprises. Findings of the study are as follows: (1) The implementation of NEDC significantly promotes green innovation among new energy enterprises, a conclusion that holds true under a series of robustness tests; (2) Further analysis suggests that, from the perspective of patent heterogeneity, the "incremental" manifestation of this policy effect is more pronounced; (3) From the perspective of ownership heterogeneity, distinct from state-owned enterprises, the promotion of green innovation among private new energy enterprises is notably significant under the policy; (4) Mechanism analysis reveals that NEDC can alter the ways in which new energy enterprises acquire and utilize funds, thereby increasing R&D investment and facilitating green innovation. The research conclusions of this paper bear certain policy implications, providing theoretical foundations and empirical references for government departments to optimize and promote NEDC.

The Impact of Japan's Cultural Diplomacy on the Construction of Japan's Traditional Cultural Soft Power
Authors: Xia Peiyan
Published: June 2024

After World War II, Japan improved its national image and soft power through a series of cultural diplomacy tools. Cultural diplomacy aims to enhance understanding and friendship among the peoples of different countries through culture-related means of external communication. Soft power, on the other hand, refers to the third aspect of a country's strength, in addition to economic and military power. Japan's cultural diplomacy has a profound impact on the construction of its traditional cultural soft power. This article adopts a longitudinal single-case study approach to sort out Japan's traditional culture, including cultural heritage, traditional skills, spiritual culture, and national character. The article finds that Japan has enhanced its goodwill towards Japan in Europe, America and Southeast Asia through its active participation in international co-operation, reform and strategic positioning of government institutions, development of tourism, cultural and artistic exchanges, and promotion of celebrity masterpieces. This suggests that the building of Japan's traditional cultural soft power can be translated into favorable feelings towards Japan among people in other countries. However, the inherent closedness of traditional culture and history-related traditional culture are the obstacles that need to be overcome in the construction of Japan's traditional cultural soft power.

Research on the Influence of CCTV Documentary City 24 Hours on Audience Subjectivity
Authors: Fan Xinyi
Published: June 2024

As an art form with reality as the core, how to make the audience have a sense of participation and play their subjectivity is a subject worth research and discussion. In recent years, under the rapid development and innovation of China’s TV documentary industry, excellent documentaries such as “A Bite of China”, “I Repair Cultural Relics in the Forbidden City” and “City 24 Hours” have been produced. However, it is undeniable that China’s documentary industry needs to improve more from the audience’s perspective to gain a higher national degree. Therefore, this paper studies the influence of the CCTV documentary series “City 24 Hours” on the audience’s subjectivity. This paper mainly studies the limitations of the documentary 24 Hour City in stimulating the subjectivity and making the audience produce “semantic democracy” for the narrative object. This includes serious labels, a lack of detail and engaging narratives, and even the mining and creation of traditional elements and online celebrity landmarks. The exploration of this series of problems and the implementation of countermeasures will be the only way in the development process of the documentary.

Authors: Ji Huihui , Xue Hongbang , Liang Jiahao
Published: June 2024

With the intensification of global climate change, it is urgent to reduce greenhouse gas emissions and protect the environment. To address this issue, it is crucial to develop the new energy industry and increase the proportion of clean energy. Tower solar power, as an innovative and environmentally friendly technology with low carbon emissions, has great potential and broad prospects. This study determines the position of the absorption tower, heliostat size, and installation height. By utilizing the ground coordinates of the heliostats and given formulas, parameters such as average optical efficiency, cosine efficiency, shadow blocking efficiency, and cut-off efficiency are calculated. The focus is on power loss caused by shading, so a shadow blocking model is constructed by using differential methods. The heliostat plane is divided into equal sections, and it is determined whether the transformed coordinates of the mirror plane are within the grid. The effective blocked area is then calculated to obtain the shadow blocking efficiency. To improve the efficiency and reduce costs of solar thermal power plants, the standard radial staggered layout in DELSOL3 empirical layout is adopted. A multi-objective optimization model is established with heliostat size and height as variables. The optimal solution for the average output thermal power per unit mirror area is obtained through genetic algorithms. Through mathematical modeling and solution methods, this study provides theoretical basis for the application of tower solar power.
Ho le mani legate!

Questo saggio ha per oggetto i provvedimenti disciplinari applicati a funzionari di polizia nel cinema poliziesco e nelle serie crime italiane. Tali misure vengono descritte dal cinema e dalla fiction come espedienti narrativi che mostrano un anti-eroe in conflitto con la società. Dal punto di vista dell’azione il personaggio assume connotati virtualmente sovversivi, ponendosi nei confronti della società come un creatore giuridico potenziale. Da un’analisi di estratti di film e serie tv, vengono esaminate le ragioni in base alle quali tale creazione giuridica non si realizza. Il comportamento del funzionario indica piuttosto il potenziale critico del genere poliziesco che si distacca dalla prospettiva dell’amusement per offrire spunti di riflessione sulla relazione tra etica dei principi e delle responsabilità. L’adozione di misure disciplinari offre l’immagine di un sistema giuridico intento a stabilizzare tensioni provenienti dall’ambiente sociale. Il reintegro in servizio del funzionario costituisce il culmine di un plot narrativo e un meccanismo riflessivo che il diritto elabora per ridefinire i propri confini accettando un determinato livello di discrezionalità da parte del funzionario sottoposto a misura disciplinare.
AN UNEXPECTED SHORT TOOTH REPLACEMENT CYCLE PERIOD IN MARESAURUS COCCAI (PLESIOSAURIA; RHOMALEOSAURIDAE) FROM THE BAJOCIAN OF ARGENTINEAN PATAGONIA
Authors: MATELO MIRCO GONZALO , O’GORMAN JOSÉ PATRICIO , GASPARINI ZULMA
Published: June 2024

The Rhomaleosauridae were a clade of Jurassic plesiosaurians, characterized by triangular skulls, elongated preorbital region, marked premaxillary-maxillary constriction, and intermediate body proportions between pliosauromorphs and plesiosauromorphs. Despite recent progress in the study of dental replacement in plesiosaurians, the replacement features in rhomaleosaurids have not been studied. Here, the dental features of the rhomaleosaurid Maresaurus coccai are described and analyzed based on the holotype specimen. Regarding symmetry, it was determined that M. coccai shows symmetrical replacement in the maxillary-premaxillary and asymmetrical replacement in the dentary. Additionally, the tooth replacement cycle period (TRCP) of two alveoli was determined for the dental series, with the exception of the anterior part of the left mandibular ramus, which presents an TRCP of three, an asymmetry considered here as teratology. This result indicates that the replacement cycle period (TRCP) of the two alveoli would correspond to a primitive character for Plesiosauria, observing an increase of TRCP from two to three alveoli in taxa comparatively more derived within Pliosauridae.

Meillä on ilo julkaista Kulutustutkimus.Nyt -lehden uusin numero kesän kynnyksellä. Numeroon sisältyy jälleen kiinnostava kattaus kulutustutkimuksellisia tutkimuksia ja keskusteluita: kaksi artikkelia, runokokoelma, kolme väitöskirjalektiota sekä kirja-arviointi.
Ensimmäinen artikkeli tuo uuden näkökulman kestävän kuluttamisen tutkimukseen pureutumalla luontokadon ja kuluttamisen väliseen yhteyteen. Artikkelissaan Henna Rouhiainen, Mitra Salimi ja Outi Uusitalo ottavat tarkempaan tarkasteluun kuluttajan kokeman riskikäsityksen ja oman toiminnan vaikuttavuuden havainnoinnin suhteessa luontokadon ehkäisyyn. Laajan kyselyaineiston tulokset paljastavat, että havainto oman toiminnan vaikuttavuudesta määrittää biodiversiteettimyönteisen kuluttajakäyttäytymisen eri muotojen toteutumista. Tutkijat suosittelevat, että kuluttajille tulisi tarjota tukea oman toiminnan vaikuttavuuden tunnistamiseen.
Toinen artikkeli käsittelee kierrättämistä ja erityisesti kuluttajien osallistumista lajittelutuotteen kehittämiseen prototyypin lanseerausvaiheessa. Artikkelissaan Henna Kokkonen ja Helen Reijonen raportoivat laadullisesta tutkimuksesta, jossa tutkittiin kuluttajien motivaatiota osallistua lajittelukäyttäytymistä edistävän tuotteen kehittämiseen sekä sitä, millaisia kulutusarvoja he tähän tuotteeseen liittivät. Tulosten mukaan kuluttajia motivoivat tuotekehitykseen erityisesti sisäiset motivaatiotekijät, kuten innostus ja kiinnostus asiaan. Lajittelutuotteeseen puolestaan liitettiin moninaisia ostamiseen ja käyttämiseen vaikuttavia kulutusarvoja. Artikkeli tuo lisäymmärrystä kuluttajalähtöiseen tuotekehitysyhteistyöhön kiertotalouden ja kestävyysmurroksen kontekstissa.
Kolmantena lukijat voivat inspiroitua Miro Penttisen runokokoelmasta ‘Fordin jälkeen’, joka koostuu kuudesta erillisestä, toisiinsa liittyvästä runosta. Penttinen kirjoittaa, että runokokoelma tulkitsee työtä ja kulutusta yhteiskunnassa, jossa halu pursuu ja arvo liukastelee. Ja todellakin, runoista välittyy kulutuksen moraalin ja oikeutuksen pohdinta tavalla, jonka vain runollinen ilmaisu mahdollistaa.
Tuoreisiin kulutustutkimuksen väitöskirjatutkimuksiin pääsee tutustumaan lukemalla lektiot Charlotta Harjulta Vaasan yliopistosta, Marilla Kortesalmelta Helsingin yliopistosta ja Taru Lehtokunnakselta Tampereen yliopistosta. Numeron lopusta löytyy kirja-arvio, jossa Visa Heinonen käy läpi Ritva Ylösen elämänkertakirjaa Laura Harmajasta, joka oli yksi suomalaisen kotitalous- ja kulutustutkimuksen uranuurtajista. Kuten Heinonen toteaa: ”teos on yksi kunnianosoitus suomalaisten naisten työlle ja osaamiselle”.
Toivotamme kaikille lehden lukijoille rentouttavaa kesää ja hyviä lukuhetkiä!

Este estudo contribui para o entendimento das estratégias legais necessárias para mitigar os riscos associados ao tráfico de dados, promovendo um ambiente digital mais seguro e protegido.
Testosterone therapy at the time of vasectomy reversal
Authors: Grober Ethan D. , Blankstein Udi
Published: June 2024

Introduction: During vasectomy reversal (VR), accurate intraoperative microscopic assessment of the vasal fluid for sperm presence and quality is essential in determining the indication for a vasovasostomy (VV) or vasoepididymostomy (VE). The use of testosterone therapy (TT), known to supress spermatogenesis, can potentially interfere with this determination. This initiative evaluated the impact of TT on vasal and epididymal fluid sperm characteristics and intraoperative decision-making among men on TT at the time of VR.
Methods: Of 2622 consecutive VRs performed from 2007–2023, patients actively using TT at the time of VR were identified. Details as to the type, dose, and duration of TT were documented. All patients were counselled regarding the impact of TT on spermatogenesis and encouraged to discontinue TT if possible. During VR, vasal and epididymal fluid (as indicated) was sampled and each aspirate underwent microscopic evaluation for sperm presence and quality, and categorized as: motile sperm/intact-non-motile sperm/sperm parts/no sperm. Rates of sperm presence/absence in the vasal/epididymal fluid, frequency of VV/VE, postoperative patency (presence of motile sperm), and semen parameters were compared among patients on TT vs. clinically matched patients not using TT at the time of VR.
Results: Among the 2622 VRs reviewed, 54 men (2%) reported using TT at the time of their VR. Despite its impact on spermatogenesis, intraoperative microscopic analysis of the reproductive fluid (vasal or epididymal) identified the presence of sperm in 95% (51/54) of patients. Testis biopsy confirmed sperm production among three patients with absence of sperm within the vasal or epididymal fluid. Rates of VV or VE did not significantly differ among men using TT at the time of VR compared to nonusers. Postoperative patency rates (TT: 78 % vs. no TT: 93%) and mean total motile sperm counts (TMC) were lower among patients using TT at the time of VR (7.9 vs. 28.3, p=0.02).
Conclusions: Use of TT at the time of VR does not appear to impact rates of intraoperative microscopic identification of sperm within the reproductive fluid or the indication for VV/VE. Postoperative patency rates and total motile sperm counts may be lowered by use of TT. Moreover, the determination to the etiology azoospermia postoperatively (production vs. obstruction) may be clouded by the use of TT during VR.

Published: June 2024

Chatbots, or conversational robots, have become a strategy or support tool for urologic patient care, diagnostic communication, and treatment. With regard to patients, studies have shown that chatbots can answer medical questions with similar percentages of acceptability as urologists. In addition, they can contribute to patient education, allowing them to ask questions that do not arise during medical consultation. They have also proven to be good tools for health promotion and disease prevention. These benefits can also serve doctors, as robots can support medical consultation and the reading of medical records, making patient care more efficient; however, there are several limitations, including the accuracy of bot-generated answers and the acceptability that urologists give to this type of tool.

A light gradient boosting machine-based method for predicting the dynamic response of functionally graded plates
Authors: Dieu Do Thi Thanh , Yen Nguyen Hoang
Published: June 2024

The primary objective of this paper is to efficiently predict the dynamic response of functionally graded plates using LightGBM – a light gradient boosting machine, without reliance on supplementary analysis tools. To obtain the optimal LightGBM model, a dataset comprising 1,000 pairs of input and output is generated through iterations using a combination of isogeometric analysis (IGA) and third-order shear deformation plate theory (TSDT). In this model, the input is represented by a power index which governs the material distribution of the plate, and the output comprises 200 values illustrating deflection over time. To demonstrate the effectiveness of LightGBM in terms of accuracy and computational time, the results obtained by the proposed model are compared to those achieved with the optimal ANN, XGBoost models, and IGA.

Uso de estadística inferencial para tratamiento de aguas congénitas con ácidos fúlvicos
Authors: Dueñas Jenny Carolina , Mora-Sanabria Rodrigo
Published: June 2024

El objetivo de esta investigación es presentar la aplicación de la estadística inferencial para los resultados de la remoción de los metales cadmio, arsénico, plomo y mercurio, por medio de la actividad quelante de los ácidos fúlvicos, extraídos de un carbón tipo lignito y aplicados como tratamiento en aguas congénitas. Los datos recolectados pertenecen a las tres formas de extracción acida, correspondientes a soluciones de 2% p/v y 0,8% p/v de ácido fúlvico extraído, liofilizado y aplicado a las aguas congénitas. Asimismo, la data seleccionada corresponde a nivel experimental y se analizan por medio del software estadístico IBM SPSS (Statistical Package for the Social Sciences) Statistics 22. Inicialmente, se realiza la prueba de distribución normal; sin embargo, se presenta información (tipo gráfico Q-Q) que demuestra que existen datos de tipo no paramétricos.
Posteriormente, se aplica una prueba de varianza que concluye que sí hay remoción de metales pesados teniendo el resultado de las mediciones de la cantidad inicial y después del tratamiento. Finalmente, haciendo uso de la prueba de comparación por pares de Mann Whitney, se llega a la conclusión de que el ácido fúlvico, después de ser liofilizado, preparado al 2% p/v y aplicado en aguas congénitas, logra la remoción de los metales cadmio, arsénico, plomo y mercurio.
Uporaba NTC metode pri otrocih v prvih treh letih
Authors: Hmelak Maja , Kirbiš Anita
Published: June 2024

V teoretičnem delu avtorici poudarjata pomen učenja po NTC metodi v zgodnjem otroštvu, natančneje do tretjega leta starosti. Z ustreznim vzgojnim delovanjem lahko odrasli vplivamo na razvoj sinaps v možganih, ki prispevajo k razvoju bioloških potencialov. Razumevanje tega je ključno pri vzgojiteljih predšolskih otrok, saj se otrok lahko vključi v vrtec že z dopolnjenimi 11. meseci starosti. V empiričnem delu smo zato raziskali poznavanje in uporabo NTC metode s strani strokovnih delavcev v vrtcu. S pomočjo anketnih vprašalnikov smo pridobljene podatke obdelali na ravni deskriptivne in inferenčne statistike. Ugotovili smo, da vzgojiteljice sicer poznajo omenjeno metodo, je pa mnoge še niso uporabile. Tiste, ki jo uporabljajo pri svojem delu, pa zaznavajo velike spremembe pri hitrejšem razvoju otrokovih potencialov na različnih razvojnih področjih.
Student Engagement in Distance Learning
Authors: Zrim Martinjak Nataša
Published: June 2024

Student engagement in distance learning was studied based on a model that includes three dimensions of engagement: behavioural, emotional and cognitive. In this study, the author aimed to ascertain how the approach to distance learning during the COVID-19 pandemic related to the other elements of each dimension of student engagement. The sample consisted of 1,167 students from the University of Ljubljana. A descriptive research method was used. Hypotheses were tested using Spearman’s rho coefficients, which confirmed the presence of statistically significant correlations between the study approach and other elements of engagement. Students who study more actively and in depth are more behaviourally, emotionally, and cognitively engaged in their studies. The validated research hypotheses also confirm the correlations between the different dimensions of engagement, thus providing insights into the multiple manifestations of student engagement. The findings can serve as a basis for developing didactic models that support student engagement through activities that promote active and in-depth learning, regardless of the context or mode of delivery of studies.

Authors: Carvalho Pacheco Lucas , Muenchen Cristiane
Published: June 2024

A perspectiva curricular crítica da Abordagem Temática caracteriza-se pela organização curricular ser estruturada em temas. Nessa perspectiva, os debates e as discussões acerca da avaliação escolar são, muitas vezes, negligenciadas. Diante disso, o problema que permeia este estudo é: Como pode-se realizar uma avaliação escolar coerente com a Abordagem Temática? Longe de fornecer densas discussões ou apresentar uma matriz a ser seguida, este artigo discute um processo de avaliação escolar em sintonia com a perspectiva curricular da Abordagem Temática, desenvolvido em uma escola pública estadual do bairro Camobi de Santa Maria/RS. Nesse sentido, este estudo caracteriza-se de natureza qualitativa, em que os instrumentos de coleta de dados foram os diários reflexivos elaborados pelo professor da turma. A análise dos dados foi realizada à luz da Análise Textual Discursiva, a partir da categoria a priori “Avaliação Escolar em sintonia com a Abordagem Temática”. A partir do exposto neste trabalho, observou-se que os modelos e critérios de avaliação utilizados ao longo das aulas contribuiu para um melhor entendimento da realidade local e uma formação crítica dos educandos, alguns dos objetivos almejados pela Abordagem Temática.
