Private Property and Labor: Seed of a New Worldview A Textual Interpretation based on the Economic and Philosophic Manuscripts of 1844
Authors: Chen Xinghui , Liu Linlin
Published: May 2024

In the Economic and Philosophic Manuscripts of 1844, young Marx addressed a novel issue: whereas traditional political economists regarded private property as an object opposed to the subject, adopting a metaphysical mode of thinking characterized by subject-object opposition, Adam Smith, referred to by Engels as the Luther of political economy, for the first time connected private property with the subject, thereby breaking away from its previous characterization as an objective, external dimension, implying signs of transcending Feuerbach. However, although Adam Smith and other political economists placed private property within human nature, due to their class limitations, they effectively treated profit-seeking activities as human nature, which is essentially a negation of humanity and diverges from human essence on the level of value. Marx, in critiquing their inherited ideas, not only links labor with private property but also understands labor as genuine, a return to the essence of humanity, as free labor rather than alienated labor, thereby laying the groundwork for the establishment of a scientific understanding of practice.

Optimization research on automatic pricing and replenishment decision method for vegetable commodities
Authors: Long Canming
Published: May 2024

This paper addresses the issues of replenishment and pricing of vegetable commodities in fresh food supermarkets. By analyzing sales data and loss rate data, mathematical models are established to solve the following problems. Spearman correlation analysis and cluster analysis methods are employed. Firstly, data preprocessing is conducted by excluding returned vegetable products from a certain supermarkets distribution, and then integrating sales transaction details and wholesale price-related data. Secondly, monthly data is used to succinctly present the sales distribution patterns of various categories and individual items of vegetables through line charts. Finally, the models of Spearman correlation analysis and cluster analysis are respectively applied to illustrate the relationship between the sales volume of 6 major categories of vegetables and 251 individual items. Linear regression models, time series analysis, and XG-Boost regression analysis models are used. This paper requires replenishment plans to be made by category, analyzing the relationship between the total sales volume and cost-plus pricing of various vegetable categories. Firstly, a linear regression model is applied to fit historical sales volume and cost-plus pricing, resulting in a linear functional relationship, indicating that only the sales volume of tomatoes is negatively correlated with cost-plus pricing. Based on historical sales data, the daily replenishment total for each vegetable category within the next week is predicted. Predictive models and time series analysis are employed. Meanwhile, for pricing strategies, the XGBoost algorithm is utilized to provide reasonable pricing strategies. Based on the optimal solution, replenishment plans and pricing strategies for the next week are formulated to ensure the maximization of sales revenue objectives.

Published: May 2024

Studies on reproductive tract score (RTS) and antral follicle count (AFC) in Senepol cattle are limited. These traits are essential as they are linked to the reproductive ability and reproductive performance of animals. Understanding the heritability and genetic correlation of these traits is crucial for guiding selection programs and selecting animals with greater reproductive efficiency and higher production potential. Therefore, this study aimed to estimate the genetic parameters of weight, RTS, and AFC in Senepol cattle using transrectal ultrasonography. Reproductive data were collected from 850 female Senepol cattle aged 10-16 months. At the time of evaluation, the following were measured: RTS traits (scores from 1 to 5), AFC (0 to 100), and female weight (kg). Variance and covariance components, genetic heritability, and correlations were estimated by univariate and bivariate analyses using the bull model. Heritability estimates were moderate for AFC (0.52) and weight (0.46), and low for RTS (0.12). The genetic correlation between RTS and AFC was almost zero (-0.05). The estimated genetic correlation between weight and AFC was -0.41, while the correlation between weight and RTS was 0.48. Selective breeding of AFC and RTS can enhance the reproductive efficiency of the herd and result in animals with earlier pubertal age and increased fertility.

The aim of this study was to evaluate the incidence of diseases as well as metabolic and zootechnical parameters in Holstein calves maintained in individual or collective housing systems in the extreme south of Brazil. One hundred calves were included immediately after birth and monitored for 90 days. Animals were randomly divided into two groups: individual stalls group (ISG; n=50) and collective stalls group (CSG; n=50). ISG calves were individually housed in 1.2m² wood pens and received 6 L of milk/day and concentrate food and water ad libitum for 90 days. Calves in the CSG were housed in groups of up to 25 animals, in a total of two stalls containing one animal per 3 m2. CSG calves received up to 8 L of milk/day at 0-15 days, milk ad libitum at 15-40 days, 7.2 L of milk. /day at 40-60 days, and gradual weaning at 60-90 days with concentrate food and water ad libitum, using an automatic feeder. In both groups, Zootechnical  parameters (weight, thoracic perimeter, height at the withers, and rump width) were measured weekly during the first 28 days and once every 15 days until weaning. Blood samples were retrieved weekly during the first 28 days. Metabolic parameters evaluated in this study were total calcium, beta-hydroxybutyrate (BHBA), free fatty acids (FFA), and glucose. The animals were monitored daily for clinical signs of diseases diarrhea and respiratory symptoms. General morbidity was higher in CSG 92% compared to ISG 74% (p<0.05). We observed increased diarrhea-related morbidity and a higher rate of recurrence in the ISG (50% and 60%, respectively; p<0.05) compared to those in the CSG (both 20%, p<0.05 between groups). The morbidity due to bronchopneumonia was higher in the CSG (92%) than in the ISG (74%, p<0.05). Recurrence of bronchopneumonia and mortality were similar between groups (p>0.05). Glucose, FFA, and BHBA concentrations were higher in the ISG (p<0.05) and total calcium higher in CSG (p<0.05). Finally, the weight and thoracic perimeter were higher in the CSG than those in the ISG, whereas the height and, rump width, at the withers was higher in the ISG than that in the CSG (p<0.05). In conclusion, animals raised in a collective system with automatic feeders exhibited less diarrhea and increased serum calcium as well as improved zootechnical development, although they had a higher incidence of bronchopneumonia.

Authors: O’Neill Dillon , Thorne Tyler J. , Scolaro John , Haller Justin M.
Published: May 2024

Tibial plateau fractures are caused by high-energy or low-energy trauma and result in complex injuries that require careful management of both osseous injuries and associated soft tissues. The posterior aspect of the tibial plateau can be involved in a variety of fracture patterns, requiring systematic evaluation, imaging, and advanced surgical planning to address these complex injuries. Early classification systems failed to classify posterior plateau fractures; however, three-dimensional imaging and newer classification schemes, including the Quadrant System and 3D systems, have incorporated posterior column lesions. There has been a growing body of literature focused on fixation principles and plating options for posterior column fractures. Furthermore, there are multiple approaches for surgeons to choose between, including a direct posterior, posteromedial, posterolateral (including Lobenhoffer and lateral condyle osteotomy), and combined posterior approach. This article presents a guide for managing posterior tibial plateau fractures, including the initial evaluation and management, descriptions of the surgical approaches, principles of fixation, and the associated outcomes and complications.

Published: May 2024

This article aims to bring clarity, based on the case law of the European Court of Human Rights, concerning the applicability of the triple test in cases of interferences admitted by national authorities in the human rights and fundamental freedoms of the citizens in their jurisdiction. In essence, the institution of the triple test, as mentioned in the judgments of the Strasbourg Court, is nothing more than a proportionality test that explains the admissible elements of such interferences and that must prove that a restriction of the exercise of a right has to be provided in the domestic law, to pursue one or more legitimate aims, as well as to be proportionate to the aims pursued and, therefore, necessary in a democratic society.

Authors: Campo Catherine Magboo , De Guzman Rhea B
Published: May 2024

Tourism bridges different aspects together. It depends most of its assets on the abundance of nature. This study was conducted in Danawan Lake, located at Sitio Darayaw, Panaytayan, Mansalay, Oriental Mindoro. This study, in partnership with the local government unit, is focused on the potential assessment of Danawan, a mountain lake, with a specific lens on gauging community perception when it comes to tourism development. Aside from the physical attributes of a destination, community participation in tourism development is very important as it will dictate its sustainability. This ethnographic study employed a qualitative approach from SWOT analysis through observation, mapping, and personal interviews. The results showed that Danawan Lake has potential for adventure and ecotourism, but its sustainable development requires careful consideration of both strengths and weaknesses, opportunities, and threats. The indigenous community living near the lake has signified their acceptance of tourism activities and development in the area if advanced communication is considered. Collaboration and inclusivity should be at hand to attain the desired goals reflecting that the community considers the lake sacred. Future researchers may use other alternative potential assessment tools to gain more in-depth findings.

A Study of College English Curriculum Innovation from the Perspective of Cross-cultural Communication
Authors: Dong Xu , Dong Guoqi
Published: May 2024

With the acceleration of globalization, cross-cultural communication has become an indispensable part of people's daily life. Effective cross-cultural communication requires an in-depth understanding and mastery of language habits, values and social norms in different cultural backgrounds. However, for a long time, college English teaching in our country has always focused on the imparting of language knowledge, lacking in-depth discussion of cultural factors such as history, humanities, and folk customs of English-speaking countries, which often leads to misunderstandings and obstacles in cross-cultural communication among students. Therefore, strengthening cultural communication in college English teaching will help students understand and use English better, and improve their cross-cultural communication ability. This study focuses on the innovation and practice of college English teaching models in the context of cross-cultural communication. Through an in-depth analysis of the current college English teaching models, it is found that the traditional teaching models have limitations in cross-cultural communication, and cannot meet the needs of cultivating students' cross-cultural communicative competence under the background of globalization. Therefore, this study proposes a series of innovative college English teaching models aimed at improving students' cross-cultural awareness, cross-cultural communicative competence and comprehensive English use ability.

Published: May 2024

With the continuous implementation of quality education, the importance of oral English teaching in junior high school English teaching is constantly increasing. Oral English is an important part of English learning, reflecting students’ language expression ability. Oral English communicative competence is one of the four basic skills in English learning and an important goal of English teaching. However, the current oral teaching quality is not very satisfactory due to the lack of an effective oral communication environment. In order to effectively improve junior high school students’ oral English level, the author takes junior high school students in grade one of a training institution as the research object and demonstrates the role of situational setting in oral English teaching to junior high school students. To determine the appropriate situation setting, factors, conditions of oral English teaching level, teaching materials, and students’ oral English level are comprehensively considered. The study of the role of situational settings in junior high school oral English teaching is conducive to a comprehensive understanding of the characteristics of situational settings and can enrich the study of junior high school students’ oral English.

Syntax and Relation Enhanced Query Generation for Text to SQL Parsing
Authors: Han Kun , Xiong Xi
Published: May 2024

Text-to-SQL parsing is the task of converting natural language questions into executable SQL queries, a significant branch of semantic parsing, which has gained increasing attention in recent years. This technology lowers the barrier for people to access databases, enhancing the convenience and availability of data. However, the primary challenge for text-to-SQL parsing lies in domain adaptation, which concerns whether the model can be applied to new databases and effectively align natural language questions with the corresponding tables or columns within the database. To address these issues, research has introduced SRSQL (Syntax and Relation-Augmented Query Generation), which incorporates syntax information and predefined relationships into the model, effectively utilizing syntactic dependencies and pattern linking to improve performance. Using a Transformer-based decoder, SRSQL generates SQL queries in the form of Abstract Syntax Trees (AST), significantly boosting prediction accuracy. Experimental results show that SRSQL outperforms comparative models, particularly on challenging benchmarks like Spider and Spider-SYN.

With regard to the existing transportation means and distribution routes of S company of C city, this paper analyzes them in terms of theoretical optimization and practical significance, aiming to reduce the cost of cold chain transportation. To this end, we determined the objective function of cold chain route optimization forS company of C city. Then, Dijkstra's algorithm is used to solve the cold chain routes. Combined with the example analysis results show that the optimization results based on Dijkstra's algorithm are reasonable and reliable. In this paper, based on the location information of S C city's stores and transit centers, as well as various data of distribution, respectively, the path optimization is carried out to ultimately achieve cost reduction and efficiency. Compared with the data of the original distribution method, both the use of transportation tools, distribution distance, and the problem of high empty rate have been improved.
