Climate change, primarily caused by human activities, poses a significant global challenge. Countries worldwide are integrating efforts to combat climate change through initiatives such as the Paris Agreement and setting targets to reach net-zero emissions by 2050. This paper explores the potential of artificial intelligence (AI) as a promising solution to address climate change, particularly through the analysis of mass data. AI can aid in environmental decision-making processes, optimize renewable energy use, and accelerate the global transition to a low-carbon economy. Using public data from the OECD, the study investigates the effectiveness of AI in promoting a low-carbon economy by examining its impact on greenhouse gas emissions, carbon footprint, investment in research and development, renewable energy production, and recycling rates. The findings suggest that AI has been considerably effective in supporting the growth of renewable energy and recycling while restraining gas emissions and carbon footprint. However, the study also identifies potential limitations, such as the carbon release from AI itself, and suggests further improvements to AI models.
主要由人类活动引起的气候变化是一项重大的全球性挑战。世界各国正在通过《巴黎协定》等倡议整合应对气候变化的努力,并设定了到 2050 年实现净零排放的目标。本文探讨了人工智能(AI)作为应对气候变化的一种有前途的解决方案的潜力,特别是通过分析海量数据。人工智能可以帮助环境决策过程,优化可再生能源的使用,加快全球向低碳经济的转型。本研究利用经合组织的公开数据,通过考察人工智能对温室气体排放、碳足迹、研发投资、可再生能源生产和回收率的影响,调查了人工智能在促进低碳经济方面的有效性。研究结果表明,人工智能在抑制气体排放和碳足迹的同时,对支持可再生能源和回收利用的增长起到了相当大的作用。不过,研究也指出了潜在的局限性,如人工智能本身的碳排放,并建议进一步改进人工智能模型。

An Alternative Multiple Contracts Version of the SACRE SACRE的可选多合同版本
Pub Date : 2023-07-17 DOI: 10.30560/jems.v6n2p19
Clovis de Faro, G. Lachtermacher
Taking into consideration that the SACRE (system of increasing amortization in real terms), as originally instituted by Caixa Econômica Federal, is not financially consistent, an exact procedure, denoted as SACRE*, was proposed in de Faro and Lachtermacher (2022). An alternative version (SACRE-F) of this system was proposed by Forger (2010). The present paper submits a multiple contract version of SACRE-F. It is shown that, taking into due account the financial institution cost of capital, it is always better to implement the multiple contracts approach instead of the single contract option. An comparison between the both alternatives are detailed.
考虑到最初由Caixa Econômica Federal制定的SACRE(按实际价值增加摊销的制度)在财务上不一致,de Faro和Lachtermacher(2022)提出了一个精确的程序,表示为SACRE*。Forger(2010)提出了该系统的替代版本(SACRE-F)。本文提出了SACRE-F的多合约版本。研究表明,在充分考虑金融机构资金成本的情况下,实施多重合同方案总是优于单一合同方案。对两种方案进行了详细的比较。

Search Algorithms for a System of Different Representatives of Subsets of a Finite Set 有限集子集的不同代表系统的搜索算法
Pub Date : 2023-06-07 DOI: 10.30560/jems.v6n2p11
D. Terzi
The paper considers various aspects and approaches regarding the search for a system of differenrt representatives (SDR) of subsets of a finite set. Algorithm 3 has been developed, which is an algorithmization of the search process for SDR on the basis of Hall's theorem on the existence of SDR. Algorithms 1-5 for searching for partial and complete SDRs based on the technology for solving problems of the transport type, in particular, the algorithm associated with the construction of cycles, are given. SDR search algorithms can be used as auxiliary tools for solving combinatorial problems. It is also shown, conversely, that the search for SDR can be considered as a combinatorial optimization problem. Mathematics Subject Classification – MSC2020: 90-08, 90B06, 90C27

The purpose of this study is to show empirical data regarding the growth of sustainability report research in Indonesia from 2009 to 2021.This study analyzed 44 articles from 21 nationally accredited journals in the Sinta 2 category. We used a charting the field approach by classifying articles based on research topic, method research, research population and external or internal factors that affect the sustainability report. The results of this study indicate that research topics discussing the linkages between financial performance and sustainability reporting in Indonesia have been extensively researched but still show inconsistencies in research results, so they need to be studied further. Furthermore, we also found that quantitative research methods, analytical research methods, public company populations and internal factors that influence sustainability reporting were the most tested by researchers.
本研究的目的是展示2009年至2021年印度尼西亚可持续发展报告研究增长的实证数据。本研究分析了来自21个国家认可的Sinta 2类期刊的44篇文章。我们采用了现场图表的方法,根据研究主题、研究方法、研究人群和影响可持续发展报告的外部或内部因素对文章进行分类。本研究的结果表明,讨论印度尼西亚财务绩效与可持续发展报告之间联系的研究课题已经得到了广泛的研究,但研究结果仍然存在不一致的地方,因此需要进一步研究。此外,我们还发现定量研究方法、分析研究方法、上市公司人口和影响可持续发展报告的内部因素被研究者检验最多。

Most research has explored ambidexterity at the organisational level and very limited research is available on individual ambidextrous behaviours. This research paper reviews the role of leaders’ regulatory focus in promoting individual ambidexterity in the form of creativity and safety. The main aim is to contribute to ambidexterity and self-regulatory literature by examining the role of leaders’ regulatory focus in managing ambidextrous behaviours. Ambidexterity is the ability to manage conflicting task demands, which poses a fundamental self-regulatory and motivational challenge in the process of pursuing different goals.
大多数研究都是在组织层面探索双灵巧性,而对个人双灵巧行为的研究非常有限。本研究回顾了领导者的监管焦点在促进个体创造性和安全性的双重灵活性方面的作用。主要目的是通过研究领导者的监管焦点在管理双灵巧行为中的作用,为双灵巧和自我监管文献做出贡献。双元性是一种管理相互冲突的任务需求的能力,在追求不同目标的过程中,这是一种基本的自我调节和动机挑战。

The aim of this research is to identify the most important benefits of using the Information technology in managing the warehouses. Knowing that the warehouse departments make use of the Warehouse management Systems (WMS) to manage their warehousing activities, but the system performs limited functions such as contacting the suppliers, as for the rest of operations such as knowing the amount of inventory, information regarding stock movement, knowing the arrival and departure schedules of trucks and many other functions etc., are performed by the warehousing staffs manually by using the papers in order to the record data. The study seeks to highlight the current use of IT in managing warehouse and identifying the shortcomings of WMS in managing warehouse. This paper will make use of literature review methodology, which will identify publications related to study highlighting the benefits of usage of information technology in managing the warehouse. The findings of the study will highlight the important benefits of using information technology in managing the Warehouses leading to more profits and efficiency for the organizations. The use of modern technology, such as big data in stock management improves the pace of work, if there is sufficient knowledge and skill when using these techniques.
本研究的目的是确定在仓库管理中使用信息技术的最重要的好处。知道仓库部门使用仓库管理系统(WMS)来管理他们的仓储活动,但该系统的功能有限,如联系供应商,至于其余的操作,如了解库存数量,有关库存移动的信息,了解卡车到达和离开的时间表等许多其他功能等,都是由仓库人员通过使用纸张手工完成的,以便记录数据。该研究旨在强调当前在仓库管理中IT的使用,并确定WMS在仓库管理中的缺点。本文将使用文献综述方法,这将确定与研究相关的出版物,强调在管理仓库中使用信息技术的好处。研究结果将强调使用信息技术管理仓库的重要好处,从而为组织带来更多的利润和效率。如果在使用这些技术时具备足够的知识和技能,那么在库存管理中使用大数据等现代技术可以提高工作速度。

Estimating the Role of Government in Socio-Economic Development in South Africa 估计政府在南非社会经济发展中的作用
Pub Date : 2022-12-31 DOI: 10.30560/jems.v5n2p34
V. Gumede
The paper examines the relationship between government and socio-economic development in South Africa. The analysis focuses on 1996-2020. Various estimations were undertaken, through the Autoregressive Distributed Lag (ARDL) model, to empirically examine the role of government in socio-economic development in South Africa. Because of the unit root that typically characterizes macroeconomic series, the unit root test using the Augmented Dick Fuller (ADF) test with constant, and trend was done. In addition, the ARDL bound tests were undertaken. The results confirm that government has an important role to play in the economy. However, results show that economic growth does not necessarily translate to socio-economic development although government spending does. In addition, results also confirm that institutions and educational spending are important for social and economic development. For instance, improvements in the quality of institutions increases the human development index. In the same vein, there is a strong positive correlation between increased socio-economic development and spending on education. Results show that the quality of institutions is important for both economic growth and socio-economic development. Overall, the findings support the view that governments should be active in facilitating social and economic development. This is more so in instances where economic performance weakens due to exogenous factors such as the coronavirus pandemic. It is worth highlighting that the baseline ARDL results show that the correlation between gross domestic product (GDP) and its prior values is statistically significant, indicating a meaningful relationship between GDP and socio-economic development.
本文考察了南非政府与社会经济发展之间的关系。分析的重点是1996-2020年。通过自回归分布滞后(ARDL)模型进行了各种估计,以经验检验政府在南非社会经济发展中的作用。由于单位根是宏观经济序列的典型特征,因此使用ADF (Augmented Dick Fuller)检验进行了单位根检验,该检验具有常数和趋势。此外,还进行了ARDL结合试验。研究结果证实,政府在经济中发挥着重要作用。然而,结果表明,经济增长不一定转化为社会经济发展,尽管政府支出可以。此外,研究结果还证实,制度和教育支出对社会和经济发展至关重要。例如,制度质量的提高提高了人类发展指数。同样,社会经济发展的增加与教育支出之间也存在着强烈的正相关关系。结果表明,制度质量对经济增长和社会经济发展都至关重要。总的来说,调查结果支持政府应该积极促进社会和经济发展的观点。在经济表现因冠状病毒大流行等外部因素而减弱的情况下,情况更是如此。值得强调的是,基线ARDL结果显示,国内生产总值(GDP)与其先前值之间的相关性在统计上显着,表明GDP与社会经济发展之间存在有意义的关系。

Jobs not Threatened by Automation in the Future in the Slovak Republic 斯洛伐克共和国未来不会受到自动化威胁的工作
Pub Date : 2022-12-14 DOI: 10.30560/jems.v5n2p22

Industry 4.0 brings with it an increase in new forms and methods of work based on automation and digitization, which gradually threaten jobs in individual countries. Most studies published on this topic describe the expected proportion of jobs that are threatened with extinction. The aim of the presented study is to investigate the opportunities that the introduction of Industry 4.0 brings with it. The presented study calculates the share of jobs with a low risk of being threatened by automation in the Slovak Republic. This is a unique approach to researching the impact of innovation trends on the labor market, which identifies jobs that are difficult to replace by machines. The calculation of the share of jobs with a low risk of being threatened by automation is based on the connection of two data sources – National system of occupations (a description of the skills required for every job in the Slovak Republic) and Information system on the price of work (modern and effective national labour cost statistical survey focus on wage earnings, including the calculation of the number of employees in individual job positions). Of the total number of 2 million working people in the Slovak Republic, 24% will not be threatened by automation. These are jobs that require at least one of the following skills for their performance: creativity, organizing and planning work, the ability to make decisions and take responsibility, leadership skills, critical thinking and talent. Several authors investigating the issue of innovations and their effects on jobs define the above-mentioned skills as difficult to be replaced by machines. The findings presented in the paper create space for further discussion at the national level about which skills and competences will need to be supported in lifelong learning among employees in order to prevent the high rate of replacement of jobs by automation, which the OECD predicts for the Slovak Republic.
工业4.0带来了基于自动化和数字化的新工作形式和方法的增加,这逐渐威胁到个别国家的就业。关于这一主题发表的大多数研究都描述了面临灭绝威胁的工作的预期比例。本研究的目的是调查引入工业4.0带来的机会。本研究计算了斯洛伐克共和国受自动化威胁风险较低的工作所占比例。这是一种研究创新趋势对劳动力市场影响的独特方法,它确定了难以被机器取代的工作。受自动化威胁风险较低的工作所占比例的计算是基于两个数据源的联系- -国家职业系统(描述斯洛伐克共和国每项工作所需的技能)和工作价格信息系统(现代和有效的国家劳动力成本统计调查侧重于工资收入,包括计算各个工作职位的雇员人数)。在斯洛伐克共和国的200万劳动人口中,24%的人不会受到自动化的威胁。这些工作至少需要以下一项技能:创造力、组织和计划工作、决策和承担责任的能力、领导能力、批判性思维和才能。几位研究创新问题及其对工作的影响的作者将上述技能定义为难以被机器取代的技能。本文提出的研究结果为在国家一级进一步讨论哪些技能和能力需要在雇员的终身学习中得到支持,以防止自动化取代工作的高比率(经合组织对斯洛伐克共和国的预测)创造了空间。

This is a unique approach to researching the impact of innovation trends on the labor market, which identifies jobs that are difficult to replace by machines. The calculation of the share of jobs with a low risk of being threatened by automation is based on the connection of two data sources – National system of occupations (a description of the skills required for every job in the Slovak Republic) and Information system on the price of work (modern and effective national labour cost statistical survey focus on wage earnings, including the calculation of the number of employees in individual job positions). \u0000Of the total number of 2 million working people in the Slovak Republic, 24% will not be threatened by automation. These are jobs that require at least one of the following skills for their performance: creativity, organizing and planning work, the ability to make decisions and take responsibility, leadership skills, critical thinking and talent. Several authors investigating the issue of innovations and their effects on jobs define the above-mentioned skills as difficult to be replaced by machines. \u0000The findings presented in the paper create space for further discussion at the national level about which skills and competences will need to be supported in lifelong learning among employees in order to prevent the high rate of replacement of jobs by automation, which the OECD predicts for the Slovak Republic.","PeriodicalId":234310,"journal":{"name":"Journal of Economics and Management Sciences","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116154155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Corporate Sustainable Practices and Profitability – Compatible? 企业可持续发展的做法和盈利能力-兼容?
Pub Date : 2022-10-12 DOI: 10.30560/jems.v5n2p13

Carbon risks and corporate social responsibility have emerged as top priorities in the global climate change agenda, leading shareholders to exert greater pressure on corporations to adopt environmental, social and governance (ESG) practices and policymakers to consider regulatory actions on carbon disclosures. Proponents stress that ESG strategies will improve financial performance, while detractors focus on their large upfront costs. The literature is inconclusive in part because it has focused predominantly on the environmental pillar alone, or ESG as a combined strategy without clearly delineating how social and governance strategies also affect corporate profitability. Distinguishing between the three pillars of ESG, this paper finds that each of these strategies individually as well as jointly are positively associated with corporate profitability. The findings are robust to firm-level controls for size and access to capital markets, as well as macroeconomic variables, and unobserved country and year fixed effects that may reflect differences in tax jurisdictions and disclosure stringency.
碳风险和企业社会责任已成为全球气候变化议程的首要任务,导致股东对企业施加更大的压力,要求其采用环境、社会和治理(ESG)实践,并促使政策制定者考虑对碳披露采取监管行动。支持者强调,ESG战略将改善财务业绩,而批评者则关注其巨大的前期成本。文献不确定的部分原因是,它们主要关注环境支柱,或者将ESG作为一种综合战略,而没有清楚地描述社会和治理战略如何影响公司盈利能力。通过对ESG的三大支柱进行区分,本文发现,无论是单独还是共同,这些战略都与企业盈利能力呈正相关。对于企业规模和资本市场准入的控制、宏观经济变量以及未观察到的国家和年度固定效应(可能反映了税收管辖和信息披露严格程度的差异),研究结果是强有力的。
