. The inclusion of sustainability criteria in the investment decision processes requires application of tools that consider the vague nature of sustainable characteristics. Fuzzy approach can process the vagueness of sustainability measures. The aim of the paper is to develop a suitable model of the fuzzy assessment of investment alternatives measured by Sustainability Utility Index. Its scheme is described methodologically as a three-stage system of multi-criteria ex-ante evaluation. An algorithmic conception of the system is performed at its third stage by a “fuzzy processor”. The fuzzy model is applied to the task of the optimal type of building machinery selection in view of the cost and sustainable criteria. The results enable the manager to optimize his/her decision, who aims to minimize the investment and operation costs of the building machinery. Compared to the fuzzy approach based on Mandani´s system, our model avoids several complications associated with the semantics of fuzzy implications in various fuzzy logics, it is more user friendly and easily algorithmized. This model is thus suitable to apply not only in corporate sphere but also in areas of ecology, sociology, economics. The limits of the fuzzy system are twofold - on the general level the fuzzy systems lack the ability to learn and memorize; determining or tuning a suitable membership function and fuzzy rules is not always clear. The challenge is first to test the model in the corporate sphere and second to acquaint potential users with this computationally undemanding fuzzy procedure.
.要在投资决策过程中纳入可持续性标准,就需要应用考虑到可持续性特征模糊性的工具。模糊方法可以处理可持续性措施的模糊性。本文的目的是建立一个合适的以可持续性效用指数衡量的投资方案模糊评估模型。其方案在方法论上被描述为一个多标准事前评估的三阶段系统。系统的算法概念在第三阶段由“模糊处理器”执行。将模糊模型应用于考虑成本和可持续性标准的建筑机械选型优化任务。这些结果使经理能够优化他的/她的决策,目的是最大限度地降低建筑机械的投资和运营成本。与基于Mandani系统的模糊方法相比,我们的模型避免了各种模糊逻辑中与模糊蕴涵语义相关的一些复杂问题,更便于用户友好和算法化。因此,该模型不仅适用于企业领域,也适用于生态学、社会学和经济学领域。模糊系统的局限性是双重的——在一般层面上,模糊系统缺乏学习和记忆能力;确定或调整合适的隶属函数和模糊规则并不总是清楚的。挑战首先是在公司领域测试该模型,其次是让潜在用户熟悉这种计算要求不高的模糊程序。

. The paper is aimed at the innovation process in the context of the business portfolio of micro-enterprises. This type of companies is typical of and prevalent in the southern region of the Czech Republic, and the presented conclusions have general validity. A newly developed method of assessing the innovative technological potential of enterprises called "Business technology assessment system" (BTAS), with the contribution of "Criteria analysis of systems". The research answers the question, what economic efficiency can innovations in the production process bring to SMEs dealing with custom manufacturing in the engineering sector. Technological backwardness including corporate infrastructure was proven. Companies compensate for this shortcoming by an increased focus on satisfying customer needs and a high degree of flexibility and innovation in production. From the point of view of production processes, there is a high degree of interconnectedness between individual operations and sub-processes. The business portfolio of most of these companies is disproportionately broad, and this is reflected in the negative findings in terms of the disproportionate number of methods and technologies that these companies possess, but do not fully utilize. Such behaviour of the companies can be explained by the absence of active creation and updating of business strategy. The economic evaluation of the innovative process (BTAS) proved that the very implementation of innovations did not lead to a major increase in the profit margin. The situation was different when evaluating the benefits of the digitization process, which brought an increase in sales and corporate margins. A completely new finding has been demonstrated, i
. 本文以微型企业的业务组合为研究对象,研究其创新过程。这种类型的公司在捷克共和国南部地区是典型和普遍的,所提出的结论具有普遍的有效性。在“系统的标准分析”的贡献下,提出了一种评价企业创新技术潜力的新方法——“企业技术评价系统”。该研究回答了这样一个问题,即生产过程中的创新能给从事工程领域定制制造的中小企业带来什么样的经济效率?包括企业基础设施在内的技术落后得到了证明。公司通过增加对满足客户需求的关注以及生产中的高度灵活性和创新来弥补这一缺点。从生产过程的角度来看,单个操作和子过程之间存在高度的相互联系。大多数这些公司的业务组合不成比例地广泛,这反映在负面调查结果中,这些公司拥有不成比例的方法和技术,但没有充分利用。企业的这种行为可以用缺乏积极的创造和更新商业战略来解释。对创新过程(BTAS)的经济评价证明,创新本身的实施并没有导致利润率的大幅增加。在评估数字化进程带来的收益时,情况就不同了,数字化进程带来了销售额和企业利润的增加。一个全新的发现已经被证明,那就是

. Managerial work in all businesses worldwide aims to achieve subordinates' successful completion of work. Assigning tasks is one of the daily activities of a manager and significantly impacts the quality of work submitted. This paper focuses on task assignments and their effectiveness in work teams. From October 2022 to January 2023, a questionnaire survey was conducted, which pursued the goal of task assignment efficiency. Respondents were asked about their preference for specific assignments, the types of information they prefer in projects, and their priorities within the work allocation. At the same time, respondents rated other aspects related to effective work assignments, such as the meaningfulness of the work, responsibility for performance or autonomy, competence to complete the task or their level of involvement and relationship with the person assigning the task. In January 2023, a focus group survey was conducted with ten students. The respondents carried out the assigned task, and the whole task process, including its outcome, was mapped. The paper presents the results of the questionnaire survey in the form of graphs, including the authors' comments with the support of more complex statistical methods; the results of the focus group are graphically displayed in a semantic differential, and the conclusion of the paper is oriented towards specific recommendations for teachers, managers, or leaders for whom assigning tasks is their daily bread.
.全球所有企业的管理工作旨在实现下属成功完成工作。分配任务是经理的日常活动之一,对提交的工作质量有很大影响。本文的重点是任务分配及其在工作团队中的有效性。从2022年10月到2023年1月,进行了一项问卷调查,追求任务分配效率的目标。受访者被问及他们对特定任务的偏好、他们在项目中更喜欢的信息类型以及他们在工作分配中的优先事项。与此同时,受访者对与有效工作任务相关的其他方面进行了评分,如工作的意义、表现或自主的责任、完成任务的能力或他们的参与程度以及与任务分配者的关系。2023年1月,对10名学生进行了一项焦点小组调查。受访者完成了分配的任务,并绘制了整个任务过程,包括其结果。本文以图表的形式介绍了问卷调查的结果,包括作者在更复杂的统计方法支持下的评论;焦点小组的结果以语义差异的形式图形化显示,论文的结论是针对教师、管理者或领导者的具体建议,对他们来说,分配任务是他们的日常面包。

. This paper reflects on the importance of employability skills for higher education students in the present and future working environment to determine the impact these skills may have on student competitiveness and satisfaction. The study focused on university students in the Madrid region during their final academic year who participated in a teaching activity that launched real business challenges. We created a model that analyzed the impact of employability skills on student competitiveness and satisfaction and the mediating role of competitiveness in two different moments (before and during the COVID-19 pandemic). Empirical findings suggest that students' improved employability skills increased their competitiveness and satisfaction, with competitiveness as a mediating factor. Thus, academic authorities must focus on students acquiring employability skills, which are among the most valuable in the labour market and positively impact student competitiveness and satisfaction. This way, future graduates can work successfully in a changing and demanding world and find positions aligned with their training. In contrast to some studies that place the teacher as the research target, ours focused on the student and the impact these skills have on the variables mentioned.
。本文反映了就业技能对高等教育学生在当前和未来工作环境中的重要性,以确定这些技能可能对学生的竞争力和满意度产生的影响。这项研究的重点是马德里地区的大学生,他们在最后一学年参加了一项教学活动,该活动引发了真正的商业挑战。我们创建了一个模型,分析了就业技能对学生竞争力和满意度的影响,以及在两个不同时刻(COVID-19大流行之前和期间)竞争力的中介作用。实证研究发现,学生就业技能的提高提高了他们的竞争力和满意度,竞争力是一个中介因素。因此,学术权威必须关注学生获得就业技能,这是劳动力市场中最有价值的技能之一,并对学生的竞争力和满意度产生积极影响。这样,未来的毕业生可以在不断变化和要求苛刻的世界中成功地工作,并找到与他们的培训相匹配的职位。与一些将教师作为研究对象的研究相反,我们的研究重点是学生以及这些技能对上述变量的影响。

. This study aims to evaluate the similarities and differences between several Smart Cities in Italy and China. For these reasons, the paper is based on two key points; the first is a broad literature review about Smart Cities to explore their evolution and identify strategic elements; the second is based on a quantitative survey of Italian and Chinese Smart Cities to show and compare common and different characteristics. The Smart City concept is a new method of seeing the city of the future. Technological and socioeconomic solutions are required for implementation concerns. Smart Cities solve local and global problems through modern technology and efficient resource management. Nonetheless, each area implements smart projects, activities, and tools as needed based on its unique concerns. There are exciting and substantial differences in Smart City implementation. The research findings present a taxonomy of parallels and differences between Italian and Chinese Smart Cities based on identified essential features

. The paper's chief goal is to determine the impact of COVID-19 on consumer purchasing behaviour and purchasing decisions concerning selected factors affecting consumers when buying food products in chain stores. The research was conducted in V4 countries, and data were obtained from a questionnaire. Essential research methods, such as analysis, synthesis, comparison, induction and deduction, were used in the presented research. Selected basic methods of descriptive statistics, normality tests and correlation coefficients were also applied. After evaluating the results of the questionnaire and verifying the research hypotheses, the expected conclusion regarding the apparent impact of COVID-19 on consumer purchasing and decision-making was confirmed. The hypothesis focused on buying behaviour in relation to gender (p = 0.03665), and economic status (p = 0.0407) was confirmed, manifesting a statistically significant relationship between these factors. A statistically significant relationship between age and buying behaviour during the COVID-19 pandemic was not confirmed (p > 0.05). The research's benefit is identifying changes in buying behaviour and consumer decision-making during the COVID-19 pandemic, which is crucial information, especially for entrepreneurs who can thus adjust their business activities to the current customer needs.
. 本文的主要目标是确定COVID-19对消费者购买行为的影响,以及在连锁店购买食品时影响消费者购买决策的选定因素。该研究在V4国家进行,数据来自问卷调查。本研究采用了分析、综合、比较、归纳、演绎等基本研究方法。选择了描述性统计、正态性检验和相关系数的基本方法。通过对问卷结果的评估和对研究假设的验证,确认了COVID-19对消费者购买和决策的明显影响的预期结论。假设关注的购买行为与性别(p = 0.03665)和经济地位(p = 0.0407)的关系得到证实,表明这些因素之间存在统计学上显著的关系。在COVID-19大流行期间,年龄与购买行为之间没有统计学上的显著关系(p > 0.05)。这项研究的好处是确定COVID-19大流行期间购买行为和消费者决策的变化,这是至关重要的信息,特别是对于能够根据当前客户需求调整业务活动的企业家。

. Despite the high level of technological and civilisational development of Western society, its prosperity and sustainability of development most directly depend on energy policy. Quite often, the field of energy security determines which countries are leading and decisive in the world economy and global competitiveness. The latest geopolitical events, namely the Russian military aggression on Ukraine's territory, showed that most European countries, including Russia itself, increasingly depend on individual energy resources. Such a situation creates serious challenges that must be promptly and effectively responded to. One of the most severe challenges is energy blackmail, which is purposefully implemented by the leadership of the Russian Federation to achieve its goals in Ukraine. The threat of destroying Ukraine's energy system is no less severe, and a humanitarian disaster may also follow in this European and Western-oriented country. Unable to defeat Ukraine on the battlefield, the Russian Federation is trying to force the Ukrainian leadership to agree to an actual capitulation by methodically destroying its energy sector.

尽管西方社会的技术和文明发展水平很高,但其繁荣和发展的可持续性最直接地取决于能源政策。能源安全领域往往决定着哪些国家在世界经济和全球竞争力中处于领先地位和决定性地位。最新的地缘政治事件,即俄罗斯对乌克兰领土的军事侵略,表明包括俄罗斯本身在内的大多数欧洲国家越来越依赖个人能源。这种情况带来了必须迅速有效应对的严重挑战。最严峻的挑战之一是能源讹诈,俄罗斯联邦领导层有意实施这一讹诈,以实现其在乌克兰的目标。摧毁乌克兰能源系统的威胁同样严重,在这个以欧洲和西方为导向的国家,人道主义灾难也可能随之而来。由于无法在战场上击败乌克兰,俄罗斯联邦正试图通过有条不紊地摧毁其能源部门,迫使乌克兰领导层同意实际投降。这表明,欧盟必须能够应对其能源部门的问题,并为其盟友提供支持,以保障能源安全。此外,这类回应必须符合国际法和国内法。
{"title":"Legal conditions of EU energy security","authors":"Jānis Teivāns-Treinovskis, Nikolajs Jefimovs, Ruta Velika, Igors Trofimovs","doi":"10.9770/jesi.2023.10.4(3)","DOIUrl":"https://doi.org/10.9770/jesi.2023.10.4(3)","url":null,"abstract":". Despite the high level of technological and civilisational development of Western society, its prosperity and sustainability of development most directly depend on energy policy. Quite often, the field of energy security determines which countries are leading and decisive in the world economy and global competitiveness. The latest geopolitical events, namely the Russian military aggression on Ukraine's territory, showed that most European countries, including Russia itself, increasingly depend on individual energy resources. Such a situation creates serious challenges that must be promptly and effectively responded to. One of the most severe challenges is energy blackmail, which is purposefully implemented by the leadership of the Russian Federation to achieve its goals in Ukraine. The threat of destroying Ukraine's energy system is no less severe, and a humanitarian disaster may also follow in this European and Western-oriented country. Unable to defeat Ukraine on the battlefield, the Russian Federation is trying to force the Ukrainian leadership to agree to an actual capitulation by methodically destroying its energy sector. This shows that the European Union must be able to respond to the problems of its energy sector and provide support to its allies to guarantee energy security. In addition, this type of response must comply with international and national law.","PeriodicalId":47127,"journal":{"name":"Entrepreneurship and Sustainability Issues","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49240025","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}

. The present study is focused on Saudi students' entrepreneurial intention and Saudi Arabian universities' role in achieving Vision 2030. The paper examines Saudi universities' role in the predictive value of students' self-efficacy, subjective norms, and attitudes towards entrepreneurship for entrepreneurial intentions. The data were collected from the student enrolled in the varied programs in Saudi universities. A total of 208 Saudi students enrolled in various disciplines, and those who attended entrepreneurial educational programs offered by the universities participated in the research. The collected data were analysed using descriptive statistics, correlation, and stepwise multiple regression analysis. Results of the study revealed that Saudi universities strengthened the students' self-reliance and positive attitude toward entrepreneurship and reduced the impact of social norms on entrepreneurial intentions.

. The study followed a consumer-centred approach in investigating the subject of visual merchandising in the South African fashion retail industry holistically. Inspired by the vision of 'Fashionomics' as a potential driver of economic growth, the primary research objective was to synthesise key visual merchandising elements to drive retail strategies in-store design and planning in the broader South African fashion retail market. This research study adopted a mixed-methods approach, analysing the data through directed content and factor analysis. This research study aims to reinvigorate South African fashion retail by targeting key visual merchandising elements, which South African fashion retailers can use as strategic tools. The key elements were determined from the consumer's perspective; hence, fashion retailers’ strategies may become more effective. Fashion retailers can differentiate themselves through the in-store environment created through unique visual merchandising strategy based on the identified critical elements and using them to gain a competitive advantage. The specified visual merchandising elements represent functions, activities, and business practices consumers value and demand. They reveal what consumers could see as a benefit to their relationship with the retailer. It was found that fashion retailers should implement good housekeeping – cleanliness and neatness, train customer-centric staff, and pay attention to fitting rooms, amongst a range of other visual merchandising elements in their retail strategies. As these three elements appear significant according to consumers, retailers will likely benefit the most by focusing on them.
该研究采用了以消费者为中心的方法,全面调查了南非时尚零售业的视觉营销主题。受“时尚学”作为经济增长潜在驱动力的愿景启发,主要研究目标是综合关键的视觉营销元素,在更广泛的南非时尚零售市场中推动商店设计和规划的零售战略。本研究采用混合方法,通过定向内容和因子分析对数据进行分析。这项研究旨在通过瞄准关键的视觉营销元素来振兴南非时尚零售业,南非时尚零售商可以将其作为战略工具。关键要素是从消费者的角度确定的;因此,时尚零售商的策略可能会变得更加有效。时尚零售商可以通过店内环境来区分自己,店内环境是通过基于已确定的关键元素的独特视觉营销策略创建的,并利用这些元素来获得竞争优势。指定的视觉商品元素代表消费者的功能、活动和商业实践价值和需求。它们揭示了消费者对他们与零售商关系的好处。研究发现,时尚零售商应在其零售策略中实施良好的内务管理——清洁和整洁,培训以客户为中心的员工,并注意试衣间以及一系列其他视觉营销元素。根据消费者的说法,这三个要素似乎很重要,零售商可能会通过关注它们而受益最大。
