摘要： In the face of limited resources, recycling, as an advanced form of resource waste recovery and treatment, can effectively achieve the comprehensive goals of optimal utilization of resources, environmental protection, and sustainable economic development. A resource waste recycling system is established in this paper that is based on the reverse logistics system in circular logistics and takes into account the requirements of resource recycling. The MILP model of stochastic planning is established by analyzing the objective function and constraints of each parameter in the system and then using the genetic algorithm to solve the optimal scheme of resource recycling planning. Example analysis shows that the planning model proposed in this paper can design a reasonable and effective plan for resource recycling in the city, and the recycling volume of plastic bottles in City Z will reach 6.85 kilotons in 2024 after the implementation of the plan, which can bring high economic benefits to the city. The model presented in this paper takes into account as many factors in resource recycling as possible, which aids in providing an accurate scientific basis for resource recycling management decisions. © 2024 Yue Zhang and Yuyin Pei, published by Sciendo.

关键词： computer science   golden-green jobs   green development   green economy   green jobs   green labor market   sustainable development  

摘要： In this article, the Scopus scientific database was searched, focusing on journals categorized under the scientific subject area of "computer science". Using a bibliometric query, scientific articles in the Scopus database were examined. The article discusses the research problem of identifying green jobs in the field of computer science, aiming to identify current and future key research areas. Unfortunately, only a portion of the results directly relate to the field of computer science, despite the articles being indexed under computer science journals. The articles analyzed were assigned to computer science, but it is not the article itself that is assigned to the discipline of "computer science", but rather the journals and the articles contained within them. The article highlights the potential for interpretative errors in the bibliometric analysis of publications assigned to the "computer science" area, especially when authors solely seek feedback relevant to this field. The article also discusses the limitations of the research and future promising research directions, such as not only "green jobs" but also "golden-green jobs". These two types of jobs are elements of the green labor market and are part of the green economy sector while simultaneously belonging to the field of computer science.

摘要： The neuropsychiatric contribution to capital sentencing proceedings has grown substantially in recent decades as the consideration of neurological and psychiatric factors in criminal behavior has been increasingly accepted as relevant to the quest for justice. This review article will focus on the legal theories underlying neuropsychiatric input into capital sentencing decisions, as well as some of the investigative techniques and resulting data which may be offered by forensic neuropsychiatrists in this context. The death penalty is unique in its severity and irreversibility, as the courts, including the U.S. Supreme Court, have noted repeatedly. "Death is different," and the recognition of this has generated a set of court decisions and statutes pertinent specifically to capital proceedings, both procedural and substantive.

摘要： Acidification and deoxygenation are major threats to ocean environments. Despite the possibilities of their cooccurrence, little is known about their interactive effects on marine organisms. The effects of low pH and low dissolved oxygen (DO) on the early life stages of the coastal fish Sillago japonica were investigated. Twenty-five experimental treatments fully crossed in five levels of pH 7.6-8.1 and DO 50-230 mu mol/kg (20-100 % saturation degree) were tested, and hatching rate of the embryos and survivability of the larvae after 24 h at 25 degrees C were investigated. Low DO treatment significantly affected the embryos and larvae compared to low pH treatment. The 50 % lethal concentration of DO showed the highest value at pH 7.6 and the lowest value at pH 7.7 and 7.9 for embryos and larvae, respectively. Therefore, effects of deoxygenation on fishes were alleviated under acidified condition around pH 7.7-7.9.

摘要： The article determines peculiarities and specifies application areas of the scientific methods of informatics and cybernetics based on V. M. Glushkov's definition of information. The concept of artificial intelligence is noted to belong to these science fields. The impossibility of using the traditional theoretical and practical foundations of discretization, quantization, and signal transmission in real-time systems is proved, and the need to develop new theoretical foundations based on the measure of changes for cybernetic systems is stressed. A tracking model of analog-incremental transformation of continuous signals with increments that are multiples to the power of 2 is proposed, as well as the methods of signal coordination with the information processing means. The expediency of using the dynamic theory of information based on the delta-entropy is stressed for distinguishing useful (dynamic) information in signals, images, videos, iterative processes, and, in general, in the data on changes in evolutionary processes. Approaches to the synthesis of new technical solutions based on the method of knowledge increments are proposed. The peculiarities of creating artificial intelligence by the methods of informatics and cybernetics and the need for their synergy with other science fields are determined.

摘要： The significance of incorporating ethics education in engineering programs has grown considerably in recent times, especially within domains such as computer science, software engineering, data science, and artificial intelligence. In response to this demand, a pedagogical activity was developed and executed to facilitate students in applying ethical theories to occupational and societal challenges while enhancing their critical thinking abilities. This activity involves students participating in a debate where they are assigned a moral stance to uphold and must utilize one of the ethical theories explored in class to bolster their case. This paper offers an in-depth account of the conception and execution of this educational activity, as well as the encouraging results observed. Furthermore, the paper showcases the scenario utilized in the activity, which outlines a professional conundrum in the realm of Computer Engineering. The findings of this educational activity indicate its efficacy as a teaching instrument for ethics in engineering programs, with potential applicability to other engineering fields. By integrating such pedagogical activities into engineering programs, educators can empower students with essential ethical values and skills to tackle intricate ethical issues in their professional and social spheres while also fostering critical thinking and encouraging dialogue among students.

关键词： Citation impact   Best paper   Peer evaluation   Academic honor   Computer science  

摘要： This paper presents a preliminary comparison of citation impact between two types of Best Paper Awards recipients: pre-and post-publication peer-selected best papers. Two hundred and ninety-nine pairs of pre-and post-publication peer-selected best papers from 15 highly prestigious computer science conferences spanning more than two decades were gathered for empirical analysis. Each pair was published in the same proceedings, and their citation information was collected within a 10-year period after their formal publication. A series of pairwise comparisons were performed in order to unbiasedly uncover their differences in citation counts (i.e., a good proxy for citation impact), as well as in citation speed, citation diversity, and citation location distributions (i.e., three characteristic properties of citation impact). The empirical results demonstrate that in computer science, the post-publication peer-selected best papers receive significantly more citations than their pre-publication counterparts, with an estimated probability of up to 0.79 (95% CI: 0.74 similar to 0.83). Meanwhile, they tend to accumulate their citations more quickly in the later (versus earlier) stages-they can scarcely be fast-aging papers, and their accumulated citations tend to cover a broader scope of academic disciplines. Overall, however, the pre-and post-publication peer-selected best papers have very similar citation location distributions. Both of them are most frequently cited in the Background sections, followed by the Methods sections, and finally the Results sections. In addition, the citation impact superiority of the post-publication peer-selected best papers remains consistent across different fields of research and over a long period of time, from 1997 to 2022.
