The Impact of Aerobics on Body Image Perception of College Students
Authors: Kuang Yulin 
Published: June 2024

This study examines the correlation between individuals' judgments of their body image and their evaluation of the advantages of aerobic exercise. A descriptive comparative- correlational approach was employed to gather data from a heterogeneous sample of participants, encompassing their demographic characteristics, evaluation of the advantages of aerobics, and judgments of body image across many dimensions. The results indicate notable disparities in the evaluation of aerobics advantages according to age and gender, as older persons and males exhibit higher ratings across several areas. Furthermore, there is a notable association between participants' evaluation of the advantages of aerobics and their opinions of their body image, emphasizing the significance of overall well-being rather than physical attractiveness. The findings of this study highlight the need to implement customized treatments and inclusive initiatives aimed at fostering a positive body image and promoting engagement in physical exercise to enhance overall health and well-being.
Smart City Construction Policy and Firm Performance: Empirical Evidence from Shanghai and Shenzhen A-share Listed Companies
Authors: Su Chenyu 
Published: June 2024

I examine the effects of digitalization and informatization on firm performance (ROE). I employed a multistage DID model, using smart city development as a natural experiment. Using a sample of Shanghai and Shenzhen listed companies, I discover that firms affected by smart city policy are more likely to have better performance. This finding is robust to a series of robustness checks. Cross-section analysis indicates that nonstate-owned firms, firms with lower power levels concentration and western firms are more likely to benefit from smart city construction. These findings can help managers and policymakers to better understand the mechanisms underlying the relationship between smart city development and firm performance and to develop tailored strategies to leverage the benefits of smart city development.
Analysis of LSTM and Derivative Models for Bitcoin Prediction Research
Authors: Ren Boyu 
Published: June 2024

Bitcoin, the first cryptocurrency, has attracted much attention in the digital currency market, and its price volatility is affected by a variety of factors, posing a challenge to investors. For the sake of analytical feasibility, many studies have adopted simplified modeling assumptions. This may overlook certain key nonlinear features of the market, such as the complexity of investor behavior and the volatility of market sentiment. This study explores the application of Long Short-Term Memory (LSTM) networks and their derivative models in predicting Bitcoin prices. Recognizing the complex nature of Bitcoin’s market dynamics, the research delves into the effectiveness of LSTM in capturing the nonlinear patterns of cryptocurrency prices. Furthermore, it extends the analysis to derivative models like MSM-LSTM and Empirical Mode Decomposition (EMD) LSTM, evaluating their ability to enhance prediction accuracy by addressing the limitations of the standard LSTM. This study provides an in-depth analysis of the effectiveness of LSTM and its derived models in the practical application of Bitcoin price prediction, with a special focus on their ability to capture non-linear patterns in the market. In Bitcoin price prediction, LSTM models have limitations but also great potential in capturing nonlinear patterns in the market. Extended models based on their own can perform well in Bitcoin price prediction. This study contributes to the field by suggesting strategies to improve the accuracy of the model and by providing ideas for developing trading strategies based on the results of the analysis.
Scurra Atticus ? Le comique de Socrate d’Athènes à Rome
Authors: Lucciano Mélanie 
Published: June 2024

Nos sources grecques sur Socrate établissent deux types de relation au comique, générique en tant que personnage de comédie, ou réflexif (par l’ironie) dans l’exercice de son activité philosophique. Nous pouvons alors définir un comique objectif (d’infériorité), dans lequel le philosophe est raillé, et un comique subjectif (de supériorité), où il ridiculise ses interlocuteurs dans un but psychagogique, le rire sanctionnant la réussite de la transmission de son enseignement. À Rome, nous assistons à une évolution de ces modèles de pensée ; chez Plaute, Socrate se métamorphose en un esclave rusé, transformant la comédie en un espace de réussite de la parole socratique, alors que cette dernière échoue dans la satire de Lucilius, par son incapacité à proposer des solutions aux problèmes passionnels. Le modèle socratique est disqualifié comme inopérant dans le domaine oratoire, frappant ses épigones de ridicule. C’est finalement dans la figure d’un Socrate farcesque que le comique acquiert de nouveau une dimension morale et protreptique ; les caractères comiques se transforment pour devenir vecteurs de philosophie.
Le rôle de l’enseignante dans le positionnement des élèves face aux objets de savoir
Authors: Moulatsa Moundounga Peggy 
Published: June 2024

L’article rend compte d’une recherche qui consiste à analyser les interactions enseignante-élèves durant des situations de parole instituées dans deux classes de maternelle afin de voir en quoi celles-ci peuvent constituer des espaces d’enseignement/apprentissages. Nous inscrivant dans la perspective de l’interactionnisme social, nous assimilons la dyade enseignante-élève à un couple d’« expert-novice ». Les analyses des interactions montrent que les enseignantes ont recours, par ordre de préférence, à : l’explicitation des rôles discursifs aux élèves, des demandes de verbalisation, l’explicitation des propos d’élèves et enfin, l’expression de soi. Cette diversité d’interactions favorise l’apprentissage des modes de régulation de la conversation collective ainsi que le développement de compétences discursives liées à la prise de parole devant le groupe-classe. Par ailleurs, l’étude des postures énonciatives prises par les maîtresses laisse penser qu’elles utilisent des stratégies éducatives différentes.
Desiring Omelette Not Breaking the Egg: Democracy, Elections and Good Governance in Africa
Authors: Adeyeye Adebowale Idowu 
Published: June 2024

The quest for good governance, development, and good life for the people which African leaders hoped will be propelled by democracy prompted them to embrace western liberal democracy However, the objective condition in many African countries reveals fundamental gap between expectations and the realities. In line with these actualities, this paper examines the differences between Africans desire for democracy and the attendant expectations and the present reality and reasons for the chasm. It examines election and electoral issues as factors in democracy and good governance. In doing this, the paper adopts content analysis of data gathered essentially from secondary sources and adopts good governance theory. The paper contends that although African leaders and people are desirous of good governance and has put in place democratic structures expected to achieve good governance, these democratic institutions, and structures; the contents and processes have not vivified good governance. It argues that the challenges of democracy and good governance in many African countries are poor election and electoral system. This is because the democratic structures and the manner of conduct of elections characterized by corruption, violence, lack of adequate ideological depth on the part of political parties and service-oriented approach to politics, personalization of, and under-performing institutions among other factors negate the principles of democracy and cannot produce good leadership and good governance. The paper concludes that though multi-party elections have been held in many countries in Africa since 1990, the quality of these elections for the advancement of democracy and by extension good governance has generated concerns and query the sense of optimism for multi-party elections. It therefore argues that for African countries to achieve the desirous goals and benefits of democracy, good governance and development, elections must be free, fair, and conducted regularly. Also, political parties and democratic institutions and structures must be adequately strengthened to function properly.
COSMARIUM RETUSIFORME VAR. INCRASSATUM GUTWIŃSKI 1890 (ZYGNEMATOPHYCEAE, STREPTOPHYTA) – NEW RECORD OF RARE DESMID IN UKRAINE
Authors: Karpenko Yurii , Mekhed Olha , Kyriienko Svitlana 
Published: June 2024

Purpose. Adding a new taxon of the genus Cosmarium to the desmids flora of Chernihiv Polesie.
Methodology. The landscape reserve of national significance “Zamglai” is one of the largest eutrophic swamps in the Chernihiv Polesie, which is an important refugium of hydrophilic phytodiversity of the forest zone, a place of concentration of a number of rare species of the boreal group and representatives of various biotic complexes. During the field research of the Zamglai bog complex, algal samples were collected and fixed with 4 % formalin for further study in laboratory conditions; pH and electrical conductivity of water were measured with a portable pH and conductivity meter. Microscopic examination of the samples was carried out using a light microscope equipped with a camera for taking microphotos. Identification manuals and monographs of the leading Ukrainian (Palamar-Mordvintseva, 1986, 2005) and European desmidiologists (Lenzenweger, 1999) were used for species identification.The iconotype provided in the original description of the newly recorded taxon (Gutwiński, 1892) was used.
Scientific novelty. The second record in Ukrainian desmidioflora of a rare taxon from the genus Cosmarium is documented. Previously it was discovered 134 years ago (Gutwiński 1890) in the Roztochchia-Opillja mountain region, namely in the vicinity of Lemberg (former Kingdom of Galicia and Lodomeria, a part of the Austro-Hungarian Monarchy – now Lviv, Ukraine). This taxon was found by the authors for the first time in the Ukrainian Polesie (Chernihiv Polesie). Description, cell dimensions and microphotographs in three views are included in this publication.
Conclusions. The description and photographs of the three cell views of the taxon given in the article fill the gaps in the illustrative material of the national reference publications (Palamar-Mordvintseva 1986: 167, fig. 37 item 16) and create better conditions for identification and new records of this taxon in Ukraine. The distribution area of Cosmarium retusiforme var. incrassatum Gutwiński 1890 has been expanded. The flora of desmids of the Ukrainian Polesie is enriched with a new infraspecific taxon.
