Companies try to survive and gain competitive advantage by leveraging their innovation capabilities, which need to be more accurately measured through company annual reports to provide valuable insights for investors and stakeholders. The study aims to analyze how innovation capability can be understood using innovative textual analysis based on linguistic cues to assess the level of a company’s innovation capability using secondary data from companies’ annual reports and then validated by empirical tests. The study surveyed 30 companies listed on the Indonesian Stock Exchange from various sectors and industries and applied panel data regression with a five-year time series (2018–2022). Innovation capability was an independent variable, measured by textual analysis approach, and return on assets (ROA) and return on equity (ROE) were dependent variables. Descriptive statistics showed no significant differences in innovation capability, ROA, and ROE across sectors. Correlation analysis revealed no significant association between company age and these variables. Panel data regression confirmed that innovation capability positively influences ROA (p-value 0.078) and ROE (p-value 0.035). Notably, the impact of innovation capability on ROA increased during and after the COVID-19 pandemic, highlighting its growing importance in financial performance during challenging times.
公司试图通过利用自身的创新能力来生存并获得竞争优势,这就需要通过公司年报来更准确地衡量创新能力,从而为投资者和利益相关者提供有价值的见解。本研究旨在分析如何利用基于语言线索的创新文本分析来理解创新能力,从而利用公司年报中的二手数据评估公司的创新能力水平,然后通过实证测试进行验证。研究调查了 30 家在印尼证券交易所上市的公司,这些公司来自不同的行业和领域,研究采用了五年时间序列(2018-2022 年)的面板数据回归。创新能力是自变量,通过文本分析方法衡量,资产回报率(ROA)和股本回报率(ROE)是因变量。描述性统计显示,各行业在创新能力、投资回报率和净资产收益率方面没有明显差异。相关分析表明,公司年龄与这些变量之间没有明显关联。面板数据回归证实,创新能力对 ROA(p 值 0.078)和 ROE(p 值 0.035)有积极影响。值得注意的是,在 COVID-19 大流行期间和之后,创新能力对投资回报率的影响有所增加,这表明在充满挑战的时期,创新能力对财务业绩的重要性与日俱增。

A circular economy has become an innovative business model, though contentious, to replace a linear economy in achieving sustainable and efficient production. This study aims to investigate the level of awareness, adoption, and effect of factors driving the circular economy adoption on the financial performance of micro, small, and medium enterprises (MSMEs) in Saudi Arabia. The survey was conducted among 301 MSMEs, and the method of logistic regression was utilized for its analysis. The results revealed that the level of awareness is averagely high, with an average of seven out of 10 enterprises. However, the outcome further showed that only an average of three out of 10 had implemented a circular economy during the period of the survey. In addition, logistic regression revealed the significant influence of drivers of circular economy adoption on the financial performance of MSMEs. The following drivers of circular economy adoption have a great likelihood and significant effect on the enterprise’s financial performance: training of employees, availability of financial resources, top management commitment, digital technology, product/service upgrade, material generated/buy back cheaper to use, and pressure from people. This is based on the outcome of logistic regression of the survey conducted on the factors driving circular economy adoption in the previous literature. However, the results revealed that regulatory incentives toward the environment and pressure from government and companies are not significant. Hence, this study provides policy implications for stakeholders in the circular economic system.
循环经济已成为一种创新的商业模式,尽管还存在争议,但它可以取代线性经济,实现可持续的高效生产。本研究旨在调查沙特阿拉伯微型、小型和中型企业(MSMEs)对循环经济的认识水平、采用情况以及推动采用循环经济的因素对其财务业绩的影响。调查对象为 301 家微型和中小型企业,采用逻辑回归法进行分析。调查结果显示,企业对财务管理的认识程度一般,平均每 10 家企业中有 7 家企业对财务管理有认识。然而,结果进一步显示,在调查期间,平均每 10 家企业中只有 3 家实施了循环经济。此外,逻辑回归显示,采用循环经济的驱动因素对中小微企业的财务绩效有显著影响。采用循环经济的以下驱动因素对企业财务绩效有很大的可能性和显著影响:员工培训、财政资源可用性、高层管理承诺、数字技术、产品/服务升级、产生/购回的材料使用成本更低、来自人们的压力。这是根据以往文献中对循环经济应用驱动因素的逻辑回归调查结果得出的。然而,结果显示,对环境的监管激励以及来自政府和企业的压力并不显著。因此,本研究为循环经济体系中的利益相关者提供了政策启示。

The aim of this study is to identify the elements that motivate employees in small and medium-sized enterprises operating in Bangladesh. The data were obtained using a survey methodology targeting employees who work in small and medium-sized enterprises located in the northern geographic region of Bangladesh. The sample included 284 employees surveyed from May 2023 to June 2023. The paper utilized a five-point Likert scale to evaluate the responses. Regression techniques were used to test the hypotheses. Moreover, to evaluate the hypotheses, a significance level of 5% was utilized, and the data pertaining to the subject matter and purpose of this study were examined using the SPSS program. The results of the paper indicate that employee motivation at SMEs is significantly influenced by employee empowerment, job security, and job training opportunities. Employee empowerment (β = 0.583) has the highest effect on motivation compared to the other two factors. Additionally, a substantial correlation coefficient (r = 0.498) is found between employee motivation and employee empowerment. This study contributes to the literature by investigating the external determinants of employee motivation within small and medium-sized enterprises.

The model of excellencism and perfectionism (MEP) theorizes that the attitude toward goals as characterized in excellencism is desirable over perfectionism. Using the self-determination theory (SDT), this study aims to investigate the varying effects of perfectionism and excellencism on work engagement and performance. The study used a time-lagged multi-phase, multi-source, and cross-sectional online survey to collect responses from 360 corporate employees of Indian companies in the services industry. The results indicate that while both perfectionism and excellencism entail pursuing high standards, they relate differently with performance and work engagement. Interestingly, excellencism and work engagement were significantly associated with performance (p < .001); however, perfectionism was insignificant (p = .989). Perfectionism strengthens work engagement (β = 0.112; p = .013), while excellencism has an insignificant effect (β = 0.035; p = .537). Work engagement fully mediates the perfectionism-performance relationship. This demonstrates that striving for excellence alone is sufficient to achieve positive performance, challenging the traditional belief that one must focus on perfection. Furthermore, perfectionism is positively associated with performance only when employees are engaged and have positive motivation toward work.
优秀主义和完美主义模型(MEP)理论认为,优秀主义中的目标态度比完美主义更可取。本研究采用自我决定理论(SDT),旨在探讨完美主义和优秀主义对工作投入和绩效的不同影响。研究采用了时滞多阶段、多来源、横截面在线调查的方法,收集了印度服务业公司 360 名企业员工的反馈。结果表明,虽然完美主义和卓越主义都需要追求高标准,但它们与绩效和工作投入的关系却不同。有趣的是,卓越主义和工作投入度与绩效有显著关联(p <.001);然而,完美主义却不显著(p = .989)。完美主义增强了工作投入度(β = 0.112; p = .013),而优秀主义的影响不明显(β = 0.035; p = .537)。工作投入完全调节了完美主义与绩效之间的关系。这表明,追求卓越本身就足以取得积极的绩效,从而挑战了人们必须注重完美的传统观念。此外,只有当员工投入工作并对工作有积极的动机时,完美主义才会与绩效正相关。

Human resources are critical assets in the hotel industry, and retaining employees is crucial for the sustainable development of hotels. To reduce employee turnover, the study aims to explore the role of psychological contract and emotional labor on turnover intention. Data from an online survey of 743 employees of luxury hotels in China were analyzed using structural equation modeling (SEM). The results show that employer relational psychological contracts (p < 0.001), employee relational psychological contracts (p < 0.001), and employer transactional psychological contracts (p < 0.01) have an impact on turnover intentions. The study also finds that employee transactional psychological contracts (p > 0.05) do not affect turnover intentions. Furthermore, employee-employer relational psychological contracts (p < 0.01) significantly influence emotional labor, whereas employer transactional psychological contracts (p > 0.05) do not. Emotional labor (p < 0.01) significantly affects turnover intentions. The connection between psychological contracts and turnover intentions is also mediated by emotional labor. These results imply that luxury hotels should prioritize employees’ emotional well-being, create a harmonious work environment, and enhance employee loyalty. This paper provides valuable insights that may reduce turnover and foster sustainable development within the hospitality sector.
人力资源是酒店业的重要资产,留住员工对酒店的可持续发展至关重要。为降低员工流失率,本研究旨在探讨心理契约和情感劳动对员工流失意向的影响。研究采用结构方程模型(SEM)对中国豪华酒店 743 名员工的在线调查数据进行了分析。结果显示,雇主关系型心理契约(p <0.001)、员工关系型心理契约(p <0.001)和雇主交易型心理契约(p <0.01)对离职意向有影响。研究还发现,员工交易型心理契约(p > 0.05)不影响离职意向。此外,员工-雇主关系型心理契约(p < 0.01)对情感劳动有显著影响,而雇主交易型心理契约(p > 0.05)则没有影响。情感劳动(p < 0.01)会明显影响离职意向。心理契约与离职意向之间的联系也是以情感劳动为中介的。这些结果表明,豪华酒店应优先考虑员工的情感健康,营造和谐的工作环境,提高员工的忠诚度。本文提供了有价值的见解,有助于降低员工流失率,促进酒店业的可持续发展。

In Jordan’s banking sector, organizations face the dual challenge of stability and innovation. Achieving this balance requires a deep grasp of leveraging capabilities for existing opportunities and exploring new ones. The key lies at the intersection of business intelligence and organizational ambidexterity. Therefore, this study has investigated the relationship between business intelligence and organizational ambidexterity within the Jordanian banking sector. It examined the impact of managerial, technical, and cultural competencies of business intelligence on organizational ambidexterity in Jordanian commercial banks listed on the Amman Stock Exchange. The quantitative study involved 449 bank employees. The data were gathered via a questionnaire, and the responses were analyzed using R language version 4.2.2. The results indicated that managerial competencies (z = 8.26, p = 0.000) and technical competencies (z = 4.09, p = 0.000) exhibit statistically significant positive direct effects on organizational ambidexterity. Additionally, cultural competencies were found to have a statistically significant direct effect on organizational ambidexterity (z = 2.083, p = 0.037). Managerial, technical, and cultural business intelligence competencies play crucial roles in the adoption of organizational ambidexterity among Jordanian commercial banks. Achieving organizational ambidexterity necessitates integrating these competencies with organizational capabilities.

An effective government agropolicy should be balanced: To reduce the state budget pressure, it is important to reduce public spending and encourage farmers to use agricultural loans. Reducing public spending should not lead to a shortage in the agricultural market. The paper aims to substantiate the directions of government agropolicy transformation based on the optimal ratio of public expenditures and loans in the agrosector and the dependence of agroproduction dynamics on state financing. The research base is data from 10 countries with different income levels (World Bank), presented in FAOSTAT for 2004–2021. For each country, the optimal (determined by the structural modeling method) and actual proportions between state financing and lending in the agrosector are compared, adjusted for the agroproduction index. The modeling showed that the share of public funds should increase in Germany, Israel, Italy, and the UK and decrease in Azerbaijan and Georgia; the current proportion is optimal in the USA, Russia, Turkey, and Ukraine. Based on a panel regression model with fixed effects, the influence of the actual level of state agrofinancing on the FAO Production Indices of the main types of agroproducts was determined. It is the largest for crops, meat, and milk (a decrease in state funding by USD 1 million threatens to reduce the respective indices by 4.5, 3.47, and 3.79 points), medium for cereals and sugar crops (according to points 2.69 and 2.11), and the smallest for livestock and non-food products (by 1.53 and 0.001 points, respectively).
有效的政府农业政策应该是平衡的:为减轻国家预算压力,必须减少公共开支,鼓励农民使用农业贷款。减少公共开支不应导致农产品市场短缺。本文旨在根据农业部门公共支出和贷款的最佳比例以及农业生产动态对国家融资的依赖性,论证政府农业政策转型的方向。研究基础是粮农组织统计数据库(FAOSTAT)中 2004-2021 年 10 个不同收入水平国家的数据(世界银行)。对每个国家的农业部门国家融资和贷款的最佳比例(由结构建模方法确定)和实际比例进行了比较,并根据农业生产指数进行了调整。建模结果表明,在德国、以色列、意大利和英国,公共资金的比例应该增加,而在阿塞拜疆和格鲁吉亚则应该减少;在美国、俄罗斯、土耳其和乌克兰,目前的比例是最佳的。基于固定效应的面板回归模型,确定了国家农业资金的实际水平对粮农组织主要农产 品生产指数的影响。对农作物、肉类和奶类的影响最大(国家资助每减少 100 万美元,相关指数就会分别下降 4.5、3.47 和 3.79 个点),对谷物和糖类作物的影响中等(分别为 2.69 和 2.11 个点),对牲畜和非食品产品的影响最小(分别为 1.53 和 0.001 个点)。

The paper aims to substantiate the directions of government agropolicy transformation based on the optimal ratio of public expenditures and loans in the agrosector and the dependence of agroproduction dynamics on state financing. The research base is data from 10 countries with different income levels (World Bank), presented in FAOSTAT for 2004–2021. For each country, the optimal (determined by the structural modeling method) and actual proportions between state financing and lending in the agrosector are compared, adjusted for the agroproduction index. The modeling showed that the share of public funds should increase in Germany, Israel, Italy, and the UK and decrease in Azerbaijan and Georgia; the current proportion is optimal in the USA, Russia, Turkey, and Ukraine. Based on a panel regression model with fixed effects, the influence of the actual level of state agrofinancing on the FAO Production Indices of the main types of agroproducts was determined. It is the largest for crops, meat, and milk (a decrease in state funding by USD 1 million threatens to reduce the respective indices by 4.5, 3.47, and 3.79 points), medium for cereals and sugar crops (according to points 2.69 and 2.11), and the smallest for livestock and non-food products (by 1.53 and 0.001 points, respectively).","PeriodicalId":509767,"journal":{"name":"Problems and Perspectives in Management","volume":"58 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663218","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}

Creating the ideal atmosphere for employees is essential to an organization’s success. Therefore, identifying the appropriate behaviors that will enhance the optimal environment can be a huge asset for an organization. This study aims to investigate the impact of mindfulness, spirituality, and core self-evaluation on task performance. Four standardized questionnaires were used to randomly collect responses via the Internet from 394 gainfully employed Saudi Arabians across multiple sectors. The samples’ age, gender, and line of work were all varied. To examine the data, structural equation modeling was applied. The findings demonstrate significant positive relationships at the 0.01 level between all examined variables. The path analysis demonstrates a significant positive relationship between spirituality and core self-evaluation (T-statistics = 4.321**) and between spirituality and task performance (T-statistics =2.613**). Furthermore, a significant positive relationship was discovered between mindfulness and core self-evaluation (T-statistics = 4.683**) and between mindfulness and task performance (T-statistics = 6.966**). In addition, a significant positive relationship has been found between core self-evaluation and performance (T-statistics = 2.247**). This suggests that mindfulness and core self-evaluation boost task performance. Additionally, mindfulness and spirituality in the workplace improve both core self-evaluation and performance.Acknowledgment This study is supported by funding from Prince Satam bin Abdulaziz University, project number (PSAU/2024/R/1445).
为员工营造理想的氛围对组织的成功至关重要。因此,确定能够提升最佳环境的适当行为对组织来说是一笔巨大的财富。本研究旨在调查正念、灵性和核心自我评价对任务绩效的影响。研究使用了四份标准化问卷,通过互联网随机收集了 394 名在多个行业有偿就业的沙特阿拉伯人的回答。样本的年龄、性别和工作领域都各不相同。为了研究数据,我们采用了结构方程模型。研究结果表明,在 0.01 的水平上,所有研究变量之间都存在明显的正相关关系。路径分析显示,灵性与核心自我评价(T 统计量=4.321**)和灵性与任务绩效(T 统计量=2.613**)之间存在显著的正相关关系。此外,在正念与核心自我评价(T 统计量 = 4.683**)以及正念与任务绩效(T 统计量 = 6.966**)之间也发现了明显的正相关关系。此外,还发现核心自我评价与工作绩效之间存在明显的正相关关系(T 统计量 = 2.247**)。这表明正念和核心自我评价能提高任务绩效。此外,工作场所中的正念和灵性还能提高核心自我评价和工作绩效。 鸣谢 本研究得到了萨塔姆-本-阿卜杜勒-阿齐兹王子大学的资助,项目编号为(PSAU/2024/R/1445)。

This paper aims to examine the crucial role of employee engagement in the operational success and resilience of small and medium-sized enterprises in the European Union, with a specific focus on the impact of age diversity on engagement strategies. Tailored engagement strategies significantly improve job satisfaction, decrease turnover rates, and promote a cohesive organizational culture. The study is based on an extensive analysis of previous research and scientific publications, providing a comprehensive overview of the current state of employee engagement practices within small and medium-sized enterprises. It explores how various age groups within the workforce perceive and react to different engagement initiatives, emphasizing the necessity for customized approaches. The paper also delves into the specific engagement tactics that have proven effective across different age demographics, such as digital tools for younger employees and recognition programs for older employees. Moreover, the paper discusses the broader implications of these findings for human resources managers and business leaders, highlighting the strategic importance of implementing age-aware engagement practices. It calls for further research to explore the long-term effects of these strategies, particularly in the context of evolving workplace dynamics and technological advancements. By adopting such tailored strategies, small and medium-sized enterprises can not only enhance employee satisfaction and retention but also foster a more innovative and adaptable organizational culture. In conclusion, this study underscores the importance of a nuanced and flexible approach to employee engagement in small and medium-sized enterprises.

Internal migration caused by the war of russia against Ukraine (with the active phase starting in February 2022) has increased the socio-economic burden on the host communities welcoming internally displaced population from the frontline and occupied territories. On the other hand, it intensifies behavioral reflections of local residents on the integration of internally displaced persons (IDPs). The study aims to identify opportunities, challenges, and prospects for IDPs’ adaptation in host communities (a case study of Lviv oblast, Ukraine). The paper conducted a sociological survey among 2,500 respondents in November 2022–February 2023. The results show that the lack of housing, lack of permanent employment, language contradictions, and forced limited contact with relatives who remain in the combat zone are existential barriers to the integration of IDPs into host communities. The study identified such opportunities for the integration of IDPs into the host society: reducing the risk of depopulation of territories, reducing imbalances in the local labor market in certain sectors of the economy, strengthening social cohesion, developing small businesses, and improving social infrastructure. The respective challenges include increased social tension, competition for jobs and housing, shortage of places in preschool institutions, and disproportionate distribution of budget funds between the local population and IDPs. Conflicts between IDPs and local residents, as well as IDPs and local authorities, require a proactive position of local authorities to initiate psychological support programs and create communication platforms for the exchange of individual experiences and discussion of psychological and emotional issues.
俄罗斯对乌克兰的战争(2022 年 2 月开始进入活跃期)造成的境内移民增加了接纳来自前线和被占领土的境内流离失所者的东道社区的社会经济负担。另一方面,这也加剧了当地居民对境内流离失所者融入社会的行为反思。本研究旨在确定国内流离失所者适应收容社区的机遇、挑战和前景(乌克兰利沃夫州案例研究)。本文于 2022 年 11 月至 2023 年 2 月对 2500 名受访者进行了社会学调查。结果表明,缺少住房、缺少长期工作、语言矛盾以及被迫与留在战区的亲属保持有限的联系是国内流离失所者融入东道社区的生存障碍。研究确定了国内流离失所者融入东道国社会的机遇:减少领土人口减少的风险、减少当地劳动力市场在某些经济部门的不平衡、加强社会凝聚力、发展小企业和改善社会基础设施。相应的挑战包括社会紧张局势加剧、就业和住房竞争加剧、学前教育机构学位短缺、预算资金在当地居民和国内流离失所者之间分配不公。国内流离失所者与当地居民以及国内流离失所者与地方当局之间的冲突要求地方当局采取积极主动的立场,启动心理支持计划,并为交流个人经历以及讨论心理和情感问题创建沟通平台。
