The existence of child slavery in supply chains is increasingly complicated because it not only applies to supply chain actors and corporations at different tiers but also to the effects of external organisations and society. This inevitable complexity is due to the global nature of today’s supply chains. Many corporate sustainability reports or corporate responsibility reports on child labour, reveal only a unilateral explanation and view, which renders the development of child labour measures under the leadership of many companies tardy and inefficient. The problem addressed in this research is the lack of comprehensive investigation into child slavery in supply chains. The primary research question is focused on identifying the key actors involved in combatting child slavery in the supply chain. The research uses thematic analysis of 68 peer-reviewed journal articles containing the keywords: child labour; supply chain, and child slavery; interchangeably in Google Scholar Search. We determined the comprehensive selection of literature by three factors: high frequency of relevant keywords; recent publication period; and more citations. The results identify four main actors influencing child slavery namely i.) Corporations - through their industrial characteristics, strategy, corporate social responsibility and internal stakeholders; ii.) Governments - through their regulations and policies and their intentions to combat child slavery; iii.) Societies through their establishment of social benchmarks and social accountability to address the social crisis; and iv.) External organisations such as ILO, NGOs and trade unions for their dominant involvement in the child slavery phenomena in supply chains. The findings provide a nascent conceptual model for empirical work and a foundation for descriptive and normative research on child slavery in supply chains.
供应链中奴役儿童现象的存在日益复杂,因为它不仅涉及供应链中不同层级的行为者和企业,还涉及外部组织和社会的影响。这种不可避免的复杂性是由当今供应链的全球性质造成的。许多关于童工问题的企业可持续发展报告或企业责任报告都只是单方面的解释和观点,这使得许多企业领导层制定童工措施的工作迟缓而低效。本研究要解决的问题是缺乏对供应链中奴役儿童现象的全面调查。主要研究问题的重点是确定参与打击供应链中奴役儿童现象的主要参与者。本研究采用专题分析法,在谷歌学术搜索中搜索了 68 篇同行评审期刊论文,其中包含的关键词有:童工、供应链和奴役儿童;这些关键词可以互换。我们通过三个因素确定了文献的综合选择:相关关键词的高频率;最近的出版时间;更多的引用。研究结果确定了影响奴役儿童现象的四个主要行为者,即 i.)企业--通过其行业特点、战略、企业社会责任和内部利益相关者; ii) 政府--通过其法规和政策以及打击奴役儿童现象的意图; iii) 社会--通过建立社会基准。社会--通过建立社会基准和社会问责制来解决社会危机;以及 iv)外部组织,如国际劳工组织、非政府组织和工会,因为它们在供应链中的奴役儿童现象中占主导地位。研究结果为实证工作提供了一个新的概念模型,并为供应链中奴役儿童问题的描述性和规范性研究奠定了基础。

Background: Transnet moves around 80% of South Africa’s rail-friendly freight tonne-kilometres, which drops to less than 40% if the rail-only coal and iron ore export lines are excluded.Objectives: Calculating the costs, negative externalities, and job losses caused by Transnet’s recent and historical operational issues and using the results to inform future reform possibilities.Method: Aspects contributing to Transnet’s failures are indicated through an assessment of rail freight’s decreasing market share and infrastructure investment, port ownership and inefficiency concerns, Transnet’s deteriorating financial performance, loss of critical skills, and instances of state capture. Resultant costs and their impact on employment are calculated across various freight flow segments, whereafter reform models are suggested through international benchmarking and extracting lessons from relevant global reforms.Results: The cost of Transnet’s failures are estimated as 7.43% of gross domestic product. A healthy relationship between the government and the private sector is a frequent occurrence in successful reforms seen globally. Locally, recent government reforms acknowledge a meaningful role for the private sector, which is in turn offering pragmatic and achievable solutions.Conclusion: Improved private sector participation can contribute to Transnet’s recovery. South Africa depends on this collaboration and the development of port and rail master plans to guide the infrastructure development required to meet its overall transportation needs.Contribution: Actionable implications for policy implementation, the economic regulation and horizontal separation of the freight railway, shifting freight from road to rail, the corporatisation of the port authority, and increasing port efficiency and capacity.
背景:南非运输公司运输的货物约占南非铁路货运吨公里的80%,如果不包括铁路运输的煤炭和铁矿石出口线路,这一比例将降至不到40%。目的:计算成本、负外部性和由Transnet近期和历史运营问题造成的失业,并利用结果为未来的改革提供信息。方法:通过对铁路货运市场份额和基础设施投资下降、港口所有权和效率低下问题、Transnet财务业绩恶化、关键技能丧失和国家俘获实例的评估,指出了导致Transnet失败的各个方面。由此产生的成本及其对就业的影响在各个货运流段进行计算,然后通过国际基准和从相关的全球改革中吸取教训,提出改革模式。结果:Transnet的失败成本估计占国内生产总值(gdp)的7.43%。在全球成功的改革中,政府和私营部门之间的健康关系经常出现。在地方上,最近的政府改革承认私营部门的重要作用,而私营部门反过来提供了务实和可实现的解决方案。结论:提高私营部门的参与度有助于Transnet的复苏。南非依靠这种合作和港口和铁路总体规划的发展来指导满足其整体运输需求所需的基础设施发展。贡献:对政策实施、经济监管和货运铁路的横向分离、将货运从公路转移到铁路、港务局的公司化以及提高港口效率和容量的可操作性影响。

Background: Logistics is an integral component for success of an organisation. So correct decision on express logistics procurement plays a critical role in success in delivering right product at right place and right time. Procurement of express logistics service is not very straight forward, instead it requires evaluation of multiple factors.Objective: The objective of this research is to create a framework of influencing factor on express logistics buying decision.Method: For the study, researchers has adopted secondary research along with primary research with group of 14 subject matter experts in field of Indian logistics sector. A group of experts comprises of senior managers, consultants and academicians with deep understanding of subject. We have used ISM (Interpretive Structural Modelling) and Cross Impact Matrix Multiplication Applied to Classification (MICMAC) to drive conceptual framework for logistics buying decision.Results: Framework shows that the decision making in logistics procurement should be highly driven by factors like network reach of Logistics Service Provider (LSP), technology followed by information sharing and strategic partnership. While service quality and cost of logistics remains as frontend factors in logistics procurement decision.Conclusion: The model output clearly suggests that final objective in buying process of express logistics is driven towards lower cost and improved service level, but it is driven by factors which directly adds value in supply chain like time to market and reverse logistics, technology and reach.Contribution: The model provides a framework for practitioners, which can enable them in decision making process of logistics procurement.
背景:物流是一个组织成功的组成部分。因此,正确的快递物流采购决策对于在正确的时间、正确的地点交付正确的产品起着至关重要的作用。快递物流服务的采购并不是很简单,而是需要对多个因素进行评估。目的:构建快递物流采购决策影响因素的研究框架。方法:在研究中,研究人员与印度物流领域的14名主题专家一起采用了二级研究和初级研究。由资深管理人员、顾问、院士组成的专家团队,对学科有着深刻的理解。我们使用了ISM(解释结构建模)和应用于分类的交叉影响矩阵乘法(MICMAC)来驱动物流购买决策的概念框架。结果:框架表明,物流采购决策应高度受物流服务提供商网络覆盖、技术等因素驱动,其次是信息共享和战略合作伙伴关系。而服务质量和物流成本仍然是影响物流采购决策的首要因素。结论:模型输出清楚地表明,快递物流采购过程的最终目标是更低的成本和更高的服务水平,但它是由直接增加供应链价值的因素驱动的,如上市时间和逆向物流、技术和到达。贡献:该模型为从业者在物流采购决策过程中提供了一个框架。

Background: Given the effervescent nature of external dynamic exasperations (EDEs) and uncertainties, this article enterprise application architecture (EAA) evaluates the probable effect on actual adoption of enterprise application architecture for supply chain management (SCM). Actual adoption (AA) of EAA is a major need for small and medium, hence the legal frameworks are there to ensure compliance on complex legal and regulatory constraints, a lack of external financing, low technological capacity, relative advantage, hardware systems and software systems compatibility.Objective: The central objective of this article is to establish whether EDEs affect the AA of EAA for SCM in SMEs, as well as supply chain success factors with five models used to identify the statistics gaps, which could be constructive for descriptive and correlational research studies.Method: A quantitative approach under correlational research is considered to investigate the relationships between variables without interventions and manipulations from the researcher.Results: To increase the reliability of measures, each variable was tested for data reliability and validity through Cronbach’s alpha and Kolmogorov-Smirnov test, chronologically. The results indicate that EDEs have a direct impact on the AA of EAA as encrypted in Analysis of Variance (ANOVA), Pearson’s coefficient and linear regression.Conclusion: The study revealed that EDEs have positive impact on the AA of EAA.Contribution: Consequently, this study makes a prominent contribution to research on the benefits of AA of EAA by signifying the effectuation theory by maintaining control on possibilities with foreseeable outcomes; then EDEs will be history.
背景:鉴于外部动态激怒(EDEs)的多变性和不确定性,本文企业应用架构(EAA)评估了供应链管理(SCM)实际采用企业应用架构的可能影响。实际采用(AA)企业应用架构是中小型企业的主要需求,因此需要法律框架来确保遵守复杂的法律法规限制、缺乏外部融资、技术能力低、相对优势、硬件系统和软件系统兼容性:本文的中心目标是确定 EDE 是否影响中小企业供应链管理中的 EAA AA 以及供应链成功因素,并使用五个模型来确定统计差距,这对描述性和相关性研究具有建设性意义:方法:考虑采用相关研究下的定量方法,在没有研究人员干预和操纵的情况下研究变量之间的关系:为了提高测量的可靠性,每个变量都按时间顺序通过 Cronbach's alpha 和 Kolmogorov-Smirnov 检验来测试数据的可靠性和有效性。结果表明,正如方差分析(ANOVA)、皮尔逊系数和线性回归所加密的那样,EDEs 对 EAA 的 AA 有直接影响:结论:研究表明,EDE 对 EAA 的 AA 有积极影响:因此,本研究通过对具有可预见结果的可能性进行控制,表明了效应理论,从而为有关监管局监管津贴的益处的研究做出了突出贡献。

Background: State-owned enterprises (SOEs) play an important role in the economies of many developed and developing countries. However, most SOEs fail to provide efficient or effective public service delivery. Therefore, it is necessary to investigate how SOEs in Gauteng province in South Africa can enhance supply chain effectiveness (SCE).Objectives: In the study, the relationships are investigated between total quality management (TQM), competitive advantage (CA), innovation (IN), SCE in the selected South African SOEs in Gauteng province.Method: A quantitative design was adopted in which a survey questionnaire was administered to 863 supply chain practitioners working in SOEs in South Africa Gauteng province. Data were analysed with the aid of Statistical Package for Social Science (SPSS 27.0) and SMART PLS (version 3.0).Results: The results of the study showed that knowledge management and CA predict the establishment of SCE in SOEs in the Gauteng province. However, IN was not supported but is of significance towards achieving SCE in SOEs in the Gauteng province.Conclusion: The adoption of CA by SOEs over industry competitors is essential toward success.Contribution: The results of this study will contribute to the improvement of South Africa’s economy by enabling SOEs to establish a competitive edge in their respective industries.
背景:国有企业在许多发达国家和发展中国家的经济中发挥着重要作用。然而,大多数国有企业未能提供高效或有效的公共服务。因此,有必要研究南非豪登省的国有企业如何提高供应链效率(SCE):本研究调查了豪滕省选定的南非国有企业中全面质量管理(TQM)、竞争优势(CA)、创新(IN)和 SCE 之间的关系:采用定量设计,向南非豪登省国有企业的 863 名供应链从业人员发放了调查问卷。借助社会科学统计软件包(SPSS 27.0)和 SMART PLS(3.0 版)对数据进行了分析:研究结果表明,知识管理和CA可预测豪登省国有企业SCE的建立。然而,IN 并未得到支持,但对豪登省国有企业实现 SCE 具有重要意义:结论:国有企业与行业竞争对手相比,采用 CA 是取得成功的关键:本研究的结果将有助于国有企业在各自行业中建立竞争优势,从而改善南非的经济状况。

Conflict of lien laws relating to the sale of abandoned goods carried by multimodal transport in Ethiopia 与埃塞俄比亚多式联运所运载的弃置货物出售有关的留置权冲突法
Q4 MANAGEMENT Pub Date : 2023-11-13 DOI: 10.4102/jtscm.v17i0.889

Background: Inland dry ports in Ethiopia serve as extended destinations for goods transported by sea, especially under the international multimodal transport system, to fulfil customs formalities. Ethiopia’s multimodal transport law gives carriers lien rights to detain cargo and documents to recover all sums payable under multimodal contracts. However, the country’s customs law gives customs the right to sell abandoned goods by auction and collect duties and taxes before any other payments are made.Objectives: This study critically examines current regulations and practices relating to carriers’ lien rights to recover uncollected charges on goods abandoned at inland dry ports.Method: A qualitative case study design is used to analyse the challenges and provide solutions for multimodal transport operators dealing with abandoned goods at inland terminals.Results: A major reason for abandonment is that the proceeds of sales of abandoned goods are insufficient to pay for taxes and logistics expenses. The Ethiopian Shipping and Logistics Services Enterprise has lost an estimated 1.5 million USD annually from abandoned containers in multimodal transport.Conclusion: Based on the legislation and court of appeal precedents presented in this paper, multimodal transport operators’ uncollected charges should take priority over tax and duties for the proceeds of selling abandoned goods. As Ethiopia is a landlocked country, it needs to resolve this issue to ameliorate its multimodal transport system.Contribution: This paper suggests revising existing regulations and practices relating to unclaimed goods at inland terminals to recoup logistics costs ahead of tax. This will facilitate multimodal transport services’ use of inland terminals as extended destinations of seaports.
背景:埃塞俄比亚内陆陆港是海上运输货物的延伸目的地,特别是在国际多式联运系统下,以履行海关手续。埃塞俄比亚的多式联运法赋予承运人扣留货物和文件的留置权,以收回多式联运合同规定的所有应付款项。然而,该国的海关法赋予海关以拍卖方式出售废弃货物的权利,并在支付任何其他款项之前收取关税和税款。目的:本研究批判性地考察了与承运人留置权有关的现行法规和做法,以收回内陆干港遗弃货物的未收费用。方法:采用定性的案例研究设计,分析多式联运经营者在处理内陆码头弃置货物时所面临的挑战,并提供解决方案。结果:弃置货物的销售收益不足以支付税费和物流费用是弃置货物的主要原因。据估计,埃塞俄比亚航运和物流服务企业每年因多式联运中的废弃集装箱而损失150万美元。结论:根据本文提出的立法和上诉法院的判例,多式联运经营者的未收费用应优先于出售废弃货物所得的税收和关税。埃塞俄比亚是一个内陆国家,需要解决这个问题,以改善其多式联运系统。贡献:本文建议修改有关内陆码头无人认领货物的现行法规和做法,以便在税收之前收回物流成本。这将有助于多式联运服务利用内陆码头作为海港的延伸目的地。

The role of African airlines in air transport liberalisation 非洲航空公司在航空运输自由化中的作用
Q4 MANAGEMENT Pub Date : 2023-10-30 DOI: 10.4102/jtscm.v17i0.925

Background: The African aviation liberalisation process began in 1988, following the liberalisation processes in Europe and the United States (US). However, by 2023, Intra-Africa air services are still reliant on the Bilateral Air Services Agreement (BASA) by which international traffic rights are exchanged in terms of the 1944 Chicago Convention, a multilateral treaty. These impose restrictions on intra-African connectivity and are obstacles to liberalisation. African multilateral initiatives, such as the Yamoussoukro Declaration, have varying levels of implementation by African states. While liberalisation efforts have major impacts on airlines, thus far these have been led by government structures. Objective: The main objectives of the study are to determine the involvement of airlines in African liberalisation development and the likely impact of the liberalisation initiatives on airline operations. Method: Semi-structured interviews were conducted with 12 intra-Africa airline executives from four Regional Economic Communities (REC), which would be impacted by liberalisation. Results: The study finds that airlines do not fully participate in the development of liberalisation initiatives. Although sometimes consulted, their associations are usually only granted observer status at deliberations and negotiations. The likely impacts of the initiatives to airlines include direct connectivity, and harmonised African air transport access. Conclusion: The lack of airline participation may be a key reason for the slow progress towards liberalisation and full deregulation in Africa. Contribution: This study contributes to the body of knowledge, by being the first study to consider the role of airlines in the development of liberalisation initiatives.
背景:继欧洲和美国的自由化进程之后,非洲航空自由化进程开始于1988年。然而,到2023年,非洲内部的航空服务仍然依赖于双边航空服务协定(BASA),根据该协定,根据1944年《芝加哥公约》(一项多边条约)交换国际航权。这些限制了非洲内部的互联互通,阻碍了自由化。非洲的多边倡议,如《亚穆苏克罗宣言》,在非洲国家的执行程度各不相同。尽管自由化努力对航空公司产生了重大影响,但迄今为止,这些努力都是由政府机构主导的。目的:本研究的主要目的是确定航空公司在非洲自由化发展中的参与情况,以及自由化举措对航空公司运营的可能影响。方法:对来自四个区域经济共同体(REC)的12名非洲内部航空公司高管进行了半结构化访谈,这些区域经济共同体将受到自由化的影响。结果:研究发现,航空公司并未充分参与自由化举措的发展。虽然有时征求他们的意见,但他们的协会通常只在审议和谈判中获得观察员地位。这些举措可能对航空公司产生的影响包括直接连接,以及协调非洲航空运输。结论:缺乏航空公司的参与可能是非洲自由化和全面放松管制进展缓慢的一个关键原因。贡献:本研究是第一个考虑航空公司在自由化举措发展中的作用的研究,对知识体系做出了贡献。

Impact of Omicron COVID-19 restrictions on air transport and tourism to and from South Africa COVID-19限制对往返南非的航空运输和旅游业的影响
Q4 MANAGEMENT Pub Date : 2023-10-27 DOI: 10.4102/jtscm.v17i0.881
Joachim Vermooten
Background: The governments of important tourist source markets imposed additional travel restrictions (the Omicron restrictions) to South Africa (and neighbouring states) as a result of the identification of the Omicron variant of COVID-19 in South Africa. These restrictions interrupted and paused the recovery in international and regional passenger traffic to and from South Africa and its neighbouring states. Objectives: To determine the impact of Omicron-related air travel restrictions on passenger demand, the number of flights operated (supply of services), average passenger loads carried and salient tourism indicators. Method: The study identifies the monthly number of passengers and flights operated before and immediately following the imposition and lifting of Omicron-related travel restrictions. The counterfactual, to determine the traffic and tourism recovery would have been had these restrictions not been imposed is made by interpolation. Results: Significant decreases in the annual number of passengers carried, flights operated and the average loads of passengers were identified within two geographic areas, international and regional traffic, on over-border flights affected by Omicron restrictions and the impact on tourism and employment. Conclusion: The Omicron restrictions interrupted the recovery trend that started to emerge and caused a decline in passenger and tourism flows, tourism spending and employment. Contribution: The study determines the impact of the Omicron restrictions on South Africa to prevent rapid government overreaction where the causation of contagion is not objectively demonstrated.
背景:由于在南非发现了COVID-19的Omicron变体,重要旅游客源市场的政府对南非(及邻国)实施了额外的旅行限制(Omicron限制)。这些限制中断和暂停了往返南非及其邻国的国际和区域客运量的恢复。目的:确定与奥米克龙相关的航空旅行限制对乘客需求、运营航班数量(服务供应)、平均载客量和主要旅游指标的影响。方法:该研究确定了在实施和解除与奥米克隆有关的旅行限制之前和之后的每月乘客和航班运营数量。反事实,以确定交通和旅游业的恢复,如果没有这些限制是由插值。结果:在国际和区域交通两个地理区域内,受Omicron限制影响的跨境航班以及对旅游和就业的影响,确定了年载客量,航班运营和平均载客量的显著下降。结论:Omicron限制措施中断了已经开始出现的复苏趋势,导致旅客和旅游流量、旅游消费和就业下降。贡献:该研究确定了Omicron限制对南非的影响,以防止在传染的原因没有客观证明的情况下政府迅速反应过度。
