PurposeThe purpose of this study is to conduct a systematic review of the literature of the studies that have examined several theoretical perspectives on corporate social performance (CSP) and identify possible future research questions based on various theoretical viewpoints.Design/methodology/approachThe study used systematic literature review analysis on a sample of 667 studies published in top A* and A category journals listed in the Australian Business Dean Council list. The present study derived articles between 1975 and 2023 from the SCOPUS database by using relevant keywords to identify research activities in CSP.FindingsThe findings suggest that many studies on CSP have been undertaken globally. But there is a lack of studies on various theoretical perspectives, including peer uncertainty evaluation, buyer–supplier sustainability links, the role of primary stakeholders (especially consumers, employees, suppliers and secondary stakeholders), the use of technology, firm-related heterogeneities, and the role of demographic and socio-economic factors. Future research areas are recommended.Research limitations/implicationsThe study investigates existing research gaps to identify possible future research questions and frameworks that can be explored to advance the research on CSP.Practical implicationsThe research also provides implications for firms in terms of understanding diverse theoretical perspectives to develop strategies to improve a firm’s social performance.Originality/value The findings are derived from a systematic review of the literature in top-category studies that examined existing theories and frameworks in the CSP domain. This highlights the importance of other understudied complementary theories, such as complexity theory, spillover theory, critical mass theory, slack theory and so on, and related variables that can improve a firm’s social performance. Evaluation of existing theoretical perspectives is not included in other review studies.
本研究的目的是对研究企业社会绩效(CSP)的几种理论观点的文献进行系统回顾,并根据各种理论观点确定未来可能的研究问题。设计/方法/方法本研究对667篇发表在澳大利亚商学院院长委员会(Australian Business Dean Council) a *和a类顶级期刊上的研究进行了系统的文献回顾分析。本研究从SCOPUS数据库中提取1975 - 2023年间的文章,使用相关关键词识别CSP的研究活动。研究结果表明,全球已经开展了许多关于CSP的研究。但缺乏对不同理论视角的研究,包括同伴不确定性评价、买方-供应商可持续性联系、主要利益相关者(特别是消费者、雇员、供应商和次要利益相关者)的作用、技术使用、企业相关异质性以及人口和社会经济因素的作用。建议未来的研究方向。研究局限/启示本研究调查了现有的研究差距,以确定未来可能的研究问题和框架,可以探索以推进CSP的研究。实践启示本研究也为企业理解不同的理论视角来制定提高企业社会绩效的战略提供了启示。原创性/价值这些发现来源于对顶级研究文献的系统回顾,这些研究考察了CSP领域现有的理论和框架。这凸显了其他尚未得到充分研究的互补理论的重要性,如复杂性理论、溢出理论、临界质量理论、松弛理论等,以及可以提高企业社会绩效的相关变量。对现有理论观点的评价不包括在其他综述研究中。

PurposeThe effectiveness of Six Sigma programs has varied across different industries and organizations, and leadership styles have been identified as a critical success factor for the installation of Six Sigma initiatives. Therefore, this study aims to investigate the specific elements of leadership styles that are linked with the successful deployment of Six Sigma programs in the automobile industry.Design/methodology/approachTo conduct the study, the researchers utilized a Likert scale questionnaire with a rating system of 1–7 and a simple random sampling method. The survey was distributed to 2,325 potential participants, with 573 responses received, mostly from Germany, the United Kingdom and Sweden. Out of those responses, 260 completed questionnaires were received. The study utilized a mixed-methods research design and exploratory research approaches to investigate the implication of leadership style on the success of Six Sigma implementation. The research employed several analysis techniques, including Structural Equation Modeling (SEM), exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and Survey methods.FindingsThrough various SEM methods, such as EFA and CFA, the study revealed two vital leadership elements: (1) the long-term success of Six Sigma depends on leadership’s support and recognition of it as an improvement strategy and (2) leadership must commit to the organization’s suppliers to ensure quality and the provision of defect-free products.Practical implicationsBy incorporating the identified key elements of leadership into their strategies, organizations and researchers can ensure the sustainable implementation of Six Sigma.Originality/valueThis research presents a distinct contribution to the evaluation of leadership style components within the European automotive sector, utilizing a mixed-methods research design and incorporating a variety of descriptive statistics.
目的六西格玛项目的有效性在不同的行业和组织中有所不同,领导风格已被确定为实施六西格玛计划的关键成功因素。因此,本研究旨在调查领导风格的具体要素,这些要素与六西格玛计划在汽车行业的成功部署有关。设计/方法/方法为了进行研究,研究人员使用了李克特量表问卷,评分系统为1-7,采用简单的随机抽样方法。这项调查共向2325名潜在参与者发放了问卷,收到了573份回复,其中大部分来自德国、英国和瑞典。在这些答复中,收到260份填妥的问卷。本研究采用混合方法研究设计和探索性研究方法,探讨领导风格对六西格玛成功实施的影响。本研究采用了结构方程模型(SEM)、探索性因子分析(EFA)、验证性因子分析(CFA)和问卷调查等分析方法。通过各种SEM方法,如EFA和CFA,研究揭示了两个重要的领导要素:(1)六西格玛的长期成功取决于领导的支持和认可它作为一种改进策略;(2)领导必须承诺组织的供应商,以确保质量和提供无缺陷的产品。实践意义通过将领导力的关键要素纳入其战略,组织和研究人员可以确保六西格玛的可持续实施。原创性/价值本研究利用混合方法研究设计并结合各种描述性统计数据,对欧洲汽车行业领导风格组成部分的评估做出了独特的贡献。

PurposeThis study proposes to understand the conditions favorable for readiness for organizational change. The analysis helps in proposing managerial interventions that would be useful for change management in an organization.Design/methodology/approachThe study employs an empirical methodology to investigate the effect of individual and organizational factors on readiness for organizational change. The study has used descriptive research design. Bivariate linear regression is used to test the hypotheses, and multiple regression is used to identify the pertinent factor that affect individual's readiness for organizational change. Thereby, a causal relationship model is proposed, using few pertinent factors which are tested using the structured equation modeling (SEM) technique.FindingsFirst, each of the factors independently has a significant effect on readiness for organizational change. Second, the prior experience of change, commitment towards organization and participation in decision-making are the pertinent factors that affect readiness for organizational change. Lastly, commitment towards organization partially mediates the relation between participation in decision-making and readiness for organizational change.Practical implicationsThe analysis helps in proposing managerial interventions that would be useful for change management in an organization. It investigates how individual and organizational characteristics influence employees' readiness for organizational change, causing them to adopt the change process.Originality/valueTo the best of the authors’ knowledge, this is one of the first studies that investigates the pertinent individual factors and the organizational factors that affect readiness for organizational change in the context of an emerging economy, India.
目的本研究旨在了解组织变革准备的有利条件。该分析有助于提出有助于组织变革管理的管理干预措施。设计/方法论/方法本研究采用实证方法来调查个人和组织因素对组织变革准备程度的影响。本研究采用描述性研究设计。双变量线性回归用于检验假设,多元回归用于确定影响个人组织变革准备程度的相关因素。因此,提出了一个因果关系模型,使用了一些相关因素,并使用结构化方程建模(SEM)技术进行了测试。发现首先,每一个因素都独立地对组织变革的准备程度产生显著影响。其次,先前的变革经验、对组织的承诺和对决策的参与是影响组织变革准备程度的相关因素。最后,对组织的承诺在一定程度上调节了参与决策和组织变革准备之间的关系。实际含义分析有助于提出有助于组织变革管理的管理干预措施。它调查了个人和组织特征如何影响员工对组织变革的准备,使他们采用变革过程。原创性/价值据作者所知,这是第一批调查印度新兴经济背景下影响组织变革准备程度的相关个人因素和组织因素的研究之一。

PurposeThe present work seeks to determine the optimal delivery schedule of equipment at a project site in the backdrop of limited storage space, at a minimum cost, and without disturbing the overall project schedule. In addition, the optimized delivery schedule helps in minimizing the fluctuating requirements of space at the project site across the entire project lifespan.Design/methodology/approachThe study is carried out at a Steel plant operating in a constrained space but undergoing a production capacity expansion. The problem motivated us to explore the possibility of postponing the delivery dates of certain equipment closer to the erection dates without compromising on the project schedule. Given the versatility of linear programming models in dealing with such schedule optimization problems, the authors formulated the above problem as a Zero-One Integer Linear Programming problem.FindingsThe model is implemented for all the new equipment arriving for two major units – the Hot Strip Mill (HSM) and the Blast Furnace (BF). It generates an optimized delivery schedule by delaying the delivery of some equipment by a certain number of periods, without compromising the overall project schedule and at a minimum storage cost. The average space utilization increases by 25.85 and 14.79% in HSM and BF units respectively. The fluctuations in space requirements are reduced substantially in both units.Originality/valueThe study shows a timeline in the form of a Gantt chart for the delivery of equipment, storage of equipment across different periods, and the number of periods for which the delivery of certain equipment needs to be postponed. The study uses linearly increasing storage costs with the increase in the number of periods for storage of the equipment in the temporary shed.HighlightsDetermined the optimal delivery schedule of the equipment in a project environment in the backdrop of limited storage space in the project site.Formulated the above problem as a Zero-One Integer Linear Programming (ILP) problem.The average space utilization has increased by 25.85 and 14.79% in HSM and BF units respectively.The optimized delivery schedule helps in reducing the fluctuations in space requirements substantially across the entire lifespan of the project.The timeline of delivery of equipment, storage of equipment across different periods and periods of postponement of the equipment are shown in the form of a Gantt Chart.
目的本工作旨在在存储空间有限的情况下,以最低的成本,在不干扰整个项目进度的情况下确定项目现场设备的最佳交付时间表。此外,优化的交付时间表有助于在整个项目使用寿命内最大限度地减少项目现场对空间的波动需求。设计/方法/方法该研究是在一家钢铁厂进行的,该钢铁厂在有限的空间内运营,但正在进行产能扩张。这个问题促使我们探索在不影响项目进度的情况下,将某些设备的交付日期推迟到更接近安装日期的可能性。考虑到线性规划模型在处理此类调度优化问题时的通用性,作者将上述问题公式化为零一整数线性规划问题。发现该模型适用于两个主要机组——热轧带钢机(HSM)和高炉(BF)的所有新设备。它通过将某些设备的交付延迟一定数量的周期来生成优化的交付时间表,而不会影响整个项目进度并以最低的存储成本。HSM和BF装置的平均空间利用率分别提高了25.85%和14.79%。两个单元的空间需求波动都大大减少。独创性/价值该研究以甘特图的形式显示了设备交付、不同时期的设备存储以及某些设备需要推迟交付的时期数量的时间表。该研究使用了随着设备在临时棚中储存周期的增加而线性增加的储存成本。亮点在项目现场存储空间有限的背景下,确定了项目环境中设备的最佳交付时间表。将上述问题公式化为零一整数线性规划(ILP)问题。HSM和BF装置的平均空间利用率分别提高了25.85%和14.79%。优化的交付时间表有助于在项目的整个生命周期内大幅减少空间需求的波动。设备交付时间表、不同时期的设备储存以及设备延期期以甘特图的形式显示。

PurposeThis article aims to investigate the financial constraints and nonlinearity of farm size growth.Design/methodology/approachFarm size growth is measured with land, labor and output using data from the Farm Accountancy Data Network (FADN) for Hungary and Slovenia. A dynamic panel model is applied to assess financial constraints and nonlinearity of farm size growth.FindingsResults show that, except for land in Slovenia and output in Hungary, liquidity constraints are less important for farm size growth than endogenous factors based on farm size growth expectations and steady farm size restructuring. Smaller farms are growing faster than larger ones. The hypothesis that a higher level of subsidies would increase farm size is not supported for Hungary. When farms reach a certain size, the land area of the largest farms increases. Farm debts in Hungary are linked with land growth and in Slovenia with output growth.Research limitations/implicationsFurther research on the impact of liquidity constraints and subsidies can be conducted at a disaggregate farm-type level to examine whether there is variability in the underlying interlinkages at the farm-type specialization level.Practical implicationsThe implication that farm size growth is dependent on initial size and that smaller farms are growing faster than bigger ones indicates that it is not necessary to favor the fastest growing smaller farms thus supports the application of a non-discriminatory farm size policy for observing farm size structural changes.Originality/valueThe dynamic panel econometric model that incorporates cash flow as a measure of financial constraints provides insight into farm size growth in cross-country comparison in relation to potential farm liquidity constraints, farm debt and the nonlinearity of farm size, which information is of relevance to policy makers and practitioners.
目的本文旨在研究农业规模增长的财务约束和非线性。设计/方法/方法利用匈牙利和斯洛文尼亚农场会计数据网络(FADN)的数据,用土地、劳动力和产出来衡量农场规模增长。应用动态面板模型来评估农场规模增长的财务约束和非线性。结果表明,除了斯洛文尼亚的土地和匈牙利的产出外,流动性约束对农场规模增长的重要性不如基于农场规模增长预期和稳定农场规模重组的内生因素。较小的农场比较大的农场生长得更快。匈牙利不支持更高水平的补贴会增加农场规模的假设。当农场达到一定规模时,最大农场的土地面积就会增加。匈牙利的农业债务与土地增长有关,斯洛文尼亚的农业债务则与产出增长有关。研究局限性/含义可以在细分农场类型层面上对流动性约束和补贴的影响进行进一步研究,以检查农场类型专业化层面的潜在相互联系是否存在可变性。实际含义农场规模增长取决于初始规模,较小的农场比较大的农场增长更快,这表明没有必要青睐增长最快的较小农场,因此支持应用非歧视性农场规模政策来观察农场规模结构变化。独创性/价值将现金流作为衡量财务约束的一种动态面板计量经济模型,在与潜在的农场流动性约束、农场债务和农场规模非线性的跨国比较中,提供了对农场规模增长的见解,这些信息与政策制定者和从业者有关。

PurposeThis paper aims to investigate the non-homogeneity in the speed of adjustment (SoA) of the capital structure of manufacturing companies. It also attempts to study the key determinants that accelerate the speed of adjustment towards the target leverage level.Design/methodology/approachUsing the dynamic panel fraction (DPF) estimator on the partial adjustment model, the study captures the heterogeneous SoA of 2,866 firms across eight prominent sectors of the Indian manufacturing industry from 2009 to 2020. To ensure robustness, the empirical inferences of DPF are cross-verified with the estimates of panel-corrected standard errors (PCSE).FindingsThe authors find a combination of the capital structure's slow, moderate and rapid adjustment speed along with the relevance of trade-off theory. Interestingly, the lowest and fastest SoA is recorded by the dwindling textile sector and expanding food and agro sector, respectively. Profitability, firm size, asset tangibility and non-debt tax shields are the key firm-specific parameters that impact the SoA towards the target.Originality/valueAvailing the rarely employed estimator ‘DPF’ and the objective of documenting diverse and non-uniform adjustment speeds across the Indian manufacturing sectors marks a novel addition to capital structure literature.
目的研究制造业企业资本结构调整速度的非同质性。它还试图研究加快向目标杠杆水平调整速度的关键决定因素。采用部分调整模型上的动态面板分数(DPF)估计器,本研究捕获了2009年至2020年印度制造业八个主要部门2,866家公司的异构SoA。为了确保稳健性,DPF的经验推断与面板校正标准误差(PCSE)的估计值进行了交叉验证。研究发现资本结构的慢、中、快速调整速度与权衡理论的相关性相结合。有趣的是,最低和最快的SoA分别记录在萎缩的纺织部门和扩大的食品和农业部门。盈利能力、公司规模、资产有形性和非债务税盾是影响SoA实现目标的关键公司特定参数。原创性/价值利用很少使用的估算器“DPF”和记录印度制造业不同和不统一的调整速度的目标,标志着资本结构文献的新补充。

PurposeWith the emergence of the basis of intellectual capital, competitive advantage was considered as the focus of competitive strategies, and the knowledge resulting from this approach became the basis for the development and strategic directions of companies in various fields of the company such as finance and accounting. The purpose of this study is sustainable intellectual capital reporting framework and evaluation of key examples in the context of capital market companies.Design/methodology/approachThe methodology of this study was exploratory from the point of view of the developmental result and based on the type of objective and qualitative and quantitative basis was used to collect the data. The statistical population in the qualitative part was university experts and in the quantitative part financial managers of capital market companies. Data collection tools were interviews in the qualitative part and fuzzy scales and language comparison checklists in the quantitative part. Therefore, first through three stages of coding, the dimensions of the model were identified, and based on the fuzzy Delphi analysis, the reliability level was determined through the average between the first round and the second round of Delphi. Finally, through the default tests, the appropriate fuzzy model was first determined, and then hierarchical fuzzy analysis based on TODIM's approach was used to determine the most favorable axis of sustainable intellectual capital reporting.FindingsThe results in the qualitative part indicate the existence of 3 categories and 6 components and 39 conceptual themes in the form of a six-dimensional model. In the quantitative part, the results showed that by confirming the dimensions identified through fuzzy Delphi analysis, the most desirable axis of intellectual capital reporting is the component of technological capital reporting, which can play a more effective role in sustainable reporting.Originality/valueThis study, relying on the importance of the consequences of sustainable intellectual capital reporting, tries to evaluate the consequences of this field of financial reporting due to the lack of a coherent theoretical framework about capital market companies. In addition, the framework presented in this study promotes integrated thinking for firms to it would provide some level of incentive to those charged with governance concerning the voluntary compliance with the sustainable intellectual capital reporting framework.
目的随着智力资本基础的出现,竞争优势被认为是竞争战略的重点,而这种方法所产生的知识成为公司在财务和会计等各个领域发展和战略方向的基础。本研究的目的是在资本市场公司的背景下,对可持续智力资本报告框架和关键例子进行评估。设计/方法论/方法本研究的方法论从发展结果的角度进行了探索,并基于客观类型和定性定量基础来收集数据。定性部分的统计人群是大学专家,定量部分是资本市场公司的财务经理。数据收集工具是定性部分的访谈,定量部分的模糊量表和语言比较清单。因此,首先通过三个阶段的编码,识别模型的维度,并基于模糊德尔菲分析,通过第一轮和第二轮德尔菲的平均值来确定可靠性水平。最后,通过默认测试,首先确定了合适的模糊模型,然后使用基于TODIM方法的层次模糊分析来确定可持续智力资本报告的最有利轴。定性部分的结果表明,以六维模型的形式存在3个类别、6个组成部分和39个概念主题。在定量部分,结果表明,通过模糊德尔菲分析确定的维度,智力资本报告最理想的轴是技术资本报告的组成部分,它可以在可持续报告中发挥更有效的作用。原创性/价值本研究基于可持续智力资本报告后果的重要性,试图评估由于缺乏关于资本市场公司的连贯理论框架而导致的财务报告领域的后果。此外,本研究中提出的框架促进了企业的综合思维,这将在一定程度上激励那些负责治理的人自愿遵守可持续知识资本报告框架。

India's youth demographic makes up one-fifth of the world's population and empowering them is crucial for the country's future success. To become a US $5 trillion economy, the Government needs to develop tailor-made strategies, policies and schemes that maximize the potential of the youth population. The Skill India Mission is one such scheme that aims to empower youth by providing necessary training and skills for the job market. However, the scheme's implementation has been plagued by various challenges such as inadequate infrastructure, low awareness, lack of quality trainers and limited industry participation. This study aims to determine the need for the Skill India Mission scheme, identify the impediments in its implementation and to propose resolutions to the problems. The study concludes that the Skill India Mission is necessary for India's economic growth and social development. Government can address the challenges of implementing the scheme by improving infrastructure, increasing industry participation and enhancing awareness.

PurposeThe vehicle routing problem (VRP) has been widely investigated during last decades to reduce logistics costs and improve service level. In addition, many researchers have realized the importance of green logistic system design in decreasing environmental pollution and achieving sustainable development.Design/methodology/approachIn this paper, a bi-objective mathematical model is developed for the capacitated electric VRP with time windows and partial recharge. The first objective deals with minimizing the route to reduce the costs related to vehicles, while the second objective minimizes the delay of arrival vehicles to depots based on the soft time window. A hybrid metaheuristic algorithm including non-dominated sorting genetic algorithm (NSGA-II) and teaching-learning-based optimization (TLBO), called NSGA-II-TLBO, is proposed for solving this problem. The Taguchi method is used to adjust the parameters of algorithms. Several numerical instances in different sizes are solved and the performance of the proposed algorithm is compared to NSGA-II and multi-objective simulated annealing (MOSA) as two well-known algorithms based on the five indexes including time, mean ideal distance (MID), diversity, spacing and the Rate of Achievement to two objectives Simultaneously (RAS).FindingsThe results demonstrate that the hybrid algorithm outperforms terms of spacing and RAS indexes with p-value <0.04. However, MOSA and NSGA-II algorithms have better performance in terms of central processing unit (CPU) time index. In addition, there is no meaningful difference between the algorithms in terms of MID and diversity indexes. Finally, the impacts of changing the parameters of the model on the results are investigated by performing sensitivity analysis.Originality/valueIn this research, an environment-friendly transportation system is addressed by presenting a bi-objective mathematical model for the routing problem of an electric capacitated vehicle considering the time windows with the possibility of recharging.
目的车辆路径问题(VRP)在过去几十年中得到了广泛的研究,以降低物流成本和提高服务水平。此外,许多研究人员已经意识到绿色物流系统设计在减少环境污染和实现可持续发展方面的重要性。设计/方法/方法本文建立了具有时间窗和部分充电的电容式电动VRP的双目标数学模型。第一个目标是最小化路线以降低与车辆相关的成本,而第二个目标是基于软时间窗口最小化到达车辆段的延迟。针对这一问题,提出了一种包括非支配排序遗传算法(NSGA-II)和基于教学的优化算法(TLBO)的混合元启发式算法,称为NSGA-II-TLBO。Taguchi方法用于调整算法的参数。基于时间、平均理想距离(MID)、多样性、,结果表明,该混合算法在间距和同时实现两个目标的比率(RAS)方面的性能优于间距和RAS指数,p值<0.04。然而,MOSA和NSGA-II算法在中央处理器(CPU)时间指数方面具有更好的性能。此外,在MID和多样性指数方面,两种算法之间没有显著差异。最后,通过灵敏度分析,研究了模型参数变化对结果的影响。独创性/价值在本研究中,通过提出一个考虑充电可能性的时间窗的电容车辆路径问题的双目标数学模型,来解决环境友好的交通系统。
