This study investigates whether all expected costs over the life cycle of metallurgical research projects are included in initial, normal and final cost estimates, and whether these costs are managed throughout a project’s life cycle since there is not enough emphasis on the accurate estimation of costs and their management over the life cycle of metallurgical research projects. The study also determines during which phase of the life cycle of metallurgical research projects’ costs are normally determined, during which phase most of the costs are incurred, and during which phase costs are managed. Project life cycles, techniques of cost estimation and cost management are examined. 10A survey was used to gather information by means of face-to-face and telephonic interviews, as well as an electronic questionnaire. The total population of entities in South Africa that conduct metallurgical research projects is small, numbering only 12 in all. The ten entities that conducted the largest metallurgical research projects in terms of average size were selected for this study. 11The conclusion drawn from the survey was that all costs over the life cycle of metallurgical research projects are not taken into account in the initial cost estimate of a project. Costs are mainly managed during the growth phase of a project and not during the introduction phase, when 80% of the costs are normally committed. The implication of this is that cost estimates for metallurgical research projects may not be accurate and costs are not necessarily managed properly throughout the life cycle of such projects. This may lead to cost overruns of project budgets, project budgets being depleted before the delivery stage and research sections running at a loss.
本研究调查了冶金研究项目生命周期内的所有预期成本是否包括在初始、正常和最终成本估算中,以及这些成本是否在项目的整个生命周期内得到管理,因为在冶金研究项目生命周期内对成本的准确估计及其管理的重视程度不够。研究还确定了冶金研究项目的成本通常在生命周期的哪个阶段确定,在哪个阶段产生大部分成本,以及在哪个阶段管理成本。项目生命周期,成本估算和成本管理的技术进行了检查。调查采用面对面访谈、电话访谈和电子问卷的方式收集信息。南非从事冶金研究项目的实体总数很少,总共只有12个。选取平均规模最大的10个冶金研究项目进行研究。11调查得出的结论是,在项目的初始成本估算中,没有考虑到冶金研究项目生命周期内的所有成本。成本主要在项目的成长阶段进行管理,而不是在通常承担80%成本的引入阶段。这意味着冶金研究项目的成本估计可能不准确,并且在这些项目的整个生命周期中成本不一定得到适当的管理。这可能导致项目预算的成本超支,项目预算在交付阶段之前就被耗尽,研究部门在亏损。

This paper reports the results of a multinomial analysis of inflation perceptions and inflation expectations in South Africa. Inflation perceptions surveys among South African individuals have been undertaken since 2006. The introduction of these surveys followed on domestic inflation expectation surveys conducted in 2000, and the use of inflation perceptions surveys internationally. Domestic inflation perceptions surveys among individuals are a private initiative undertaken biennially, while domestic inflation expectation surveys among individuals are funded by the South African Reserve Bank and are undertaken quarterly. By comparing the results of domestic inflation perceptions surveys and inflation expectation surveys undertaken since 2006, this paper establishes common characteristics that impact on the formulation of inflation perceptions and inflation expectations. It supplements earlier research that focused only on the results of the 2006 and 2008 perceptions survey results. With the completion of the third biennial inflation perceptions survey in 2010, more data sets are available for the purposes of comparison. Furthermore, the questions on inflation perceptions were expanded in the third survey. Although this provides for a broader basis of analysis between inflation perceptions surveys and inflation expectation surveys, further periodic inflation perceptions survey data will be required to test whether current inflation figures determine and anchor inflation expectations.
本文报告了南非通货膨胀认知和通货膨胀预期的多项分析结果。自2006年以来,南非人对通货膨胀的看法进行了调查。这些调查是继2000年进行的国内通胀预期调查和国际上使用的通胀认知调查之后推出的。对个人的国内通货膨胀看法调查是一项私人倡议,每两年进行一次,而对个人的国内通货膨胀预期调查则由南非储备银行资助,每季度进行一次。通过比较2006年以来国内通胀感知调查和通胀预期调查的结果,本文建立了影响通胀感知和通胀预期形成的共同特征。它补充了早期的研究,这些研究只关注2006年和2008年的看法调查结果。随着第三次两年一次的通胀认知调查于2010年完成,更多的数据集可用于比较。此外,在第三次调查中,有关通胀认知的问题有所扩大。尽管这为通胀感知调查和通胀预期调查之间的分析提供了更广泛的基础,但需要进一步的定期通胀感知调查数据来检验当前的通胀数据是否决定和锚定通胀预期。

The objective of this study was to explore the relationship between job insecurity, organisational commitment and work engagement among staff in an open distance learning institution. The research was conducted through computer-aided telephone interviews and self-completion techniques. A cross-sectional survey design was conducted among 260 employees in an open distance learning institution. The measuring instruments included the job insecurity scale, organisational commitment questionnaire and Utrecht Work Engagement Scale. The results demonstrated statistically significant relationships between job insecurity and organisational commitment, and between job insecurity and work engagement. A practically significant relationship between variables was also determined; however, the effect was too small to yield a practically significant relationship between the variables. The results revealed that a component of job insecurity (likelihood of loss of job features), together with a component of work engagement (vigour), explains 25% of the total variation of organisational commitment and that the remaining 75% was attributed to factors beyond the scope of this study. This study demonstrated that employees would not always reduce their commitment and work effort when confronted with uncertainty as suggested by several studies. Nevertheless, it could be assumed that the survey participants fear being unemployed and feel trapped because of a lack of alternative employment opportunities.
摘要本研究旨在探讨远程开放教育机构员工的工作不安全感、组织承诺和工作投入之间的关系。该研究是通过计算机辅助电话访谈和自我完成技术进行的。采用横断面调查设计对某开放远程教育机构260名员工进行调查。测量工具包括工作不安全感量表、组织承诺问卷和乌得勒支工作投入量表。结果表明,工作不安全感与组织承诺、工作不安全感与工作投入之间存在显著的统计学关系。还确定了变量之间具有实际意义的关系;然而,这种影响太小,不足以产生变量之间的实际显著关系。结果显示,工作不安全感(失去工作特征的可能性)和工作投入(活力)组成部分解释了组织承诺总变化的25%,其余75%归因于本研究范围之外的因素。本研究表明,当面临不确定性时,员工并不总是会像一些研究表明的那样减少他们的承诺和工作努力。然而,可以假设调查参与者害怕失业,因为缺乏其他就业机会而感到被困。

For banks, fair value adjustments do influence dividend policy 对银行而言,公允价值调整确实会影响股息政策
IF 0.6 Q3 LAW Pub Date : 2019-02-26 DOI: 10.25159/1998-8125/5812

5Most researchers who investigate the interplay between fair value accounting (FVA) and the financial crisis look at the time period during the crisis. This paper investigates a potential role for FVA prior to the crisis: If FVA led to increased accounting profits with the recognition of transitory gains through profit and loss during the boom, and if those increased profits provided the rationale for increased dividends, then bank capital became riskier prior to the crisis, and this would have made the system more prone to failure. A study by Goncharov and Van Triest (2011) found no empirical support for an increase in dividends in response to unrealised positive fair value adjustments to income. In contrast, when the setting is limited to only South African banks, this paper finds that South African banks did pay dividends from unrealised transitory gains. This finding is based on a combination of three strands of evidence: a panel regression of the annual dividends declared by the large South African universal banks that showed that those banks probably ignored the unrealised nature of FVA profits when dividends were determined; monthly data from the total South African bank system in a co-integrated regression that showed that unrealised fair value profits from the banking book raised the average level of bank profits materially; and simple descriptive statistics on distributions that showed that South African banks distributed a greater proportion of profits during the critical period of 2004 to 2008 when unrealised fair value profits from the banking book raised the level of bank profits. The finding that South African banks did pay dividends from unrealised transitory gains was also confirmed by bank representatives and the post-financial crisis disclosure of one of the South African banks.
大多数研究公允价值会计(FVA)与金融危机之间相互作用的研究人员都着眼于危机期间。本文研究了危机前FVA的潜在作用:如果FVA导致会计利润增加,在繁荣时期通过损益确认短暂收益,如果这些增加的利润为增加股息提供了理由,那么银行资本在危机前变得更有风险,这将使系统更容易失败。Goncharov和Van Triest(2011)的一项研究发现,对于未实现的正公允价值调整对收入的影响,股息的增加没有实证支持。相比之下,当设置仅限于南非银行时,本文发现南非银行确实从未实现的暂时性收益中支付股息。这一发现是基于三种证据的结合:对南非大型全能银行宣布的年度股息进行的面板回归,结果表明,在确定股息时,这些银行可能忽略了FVA利润的未实现性质;在协整回归中,来自整个南非银行系统的月度数据显示,银行账面上未实现的公允价值利润大幅提高了银行利润的平均水平;以及关于分配的简单描述性统计数据,显示南非银行在2004年至2008年的关键时期分配了更大比例的利润,当时银行账面上未实现的公允价值利润提高了银行利润水平。银行代表和一家南非银行在金融危机后披露的情况,也证实了南非银行确实从未实现的暂时性收益中支付股息的发现。

This study investigates the process of index construction as a means of measuring a hypothetical construct that can typically not be measured by a single question or item and applying it as a method of market segmentation. The availability of incidental secondary data provided a relevant quantitative basis to illustrate this process by constructing a commercial farming sophistication index for South Africa. It was evident that this approach offers an appropriate and useful means of segmenting a market. Several factors contribute to the appeal of this approach. Among others, it addresses important priorities in the area of future segmentation research. By offering classification rules based on characteristics that can easily be observed or elicited through asking a few key questions, new or potential buyers can be grouped by buying behaviour segment. Furthermore, the multi-step process that was employed provides a systematic and structured multivariate approach to segmentation. It also facilitates replication of the process when conducting future studies. Lastly, the outcome of this type of segmentation method offers researchers and marketing practitioners a procedure, in the form of an equation, to calculate index scores and provide rules to segment the market based on predefined intervals. Hence, the challenge to replicate segment formation across independent future studies is addressed.
本研究探讨了指数建构的过程,作为一种测量通常无法通过单一问题或项目测量的假设结构的手段,并将其应用于市场细分的方法。附带的二手数据的可用性提供了相关的定量基础,通过构建南非的商业农业成熟度指数来说明这一过程。显然,这种方法提供了一种适当和有用的细分市场的手段。有几个因素促成了这种方法的吸引力。其中,它解决了未来细分研究领域的重要优先事项。通过提供基于特征的分类规则,这些特征可以通过询问几个关键问题轻松观察或引出,新的或潜在的买家可以根据购买行为细分进行分组。此外,所采用的多步骤过程提供了一种系统的、结构化的多变量分割方法。它还有助于在进行未来研究时复制这一过程。最后,这种类型的分割方法的结果为研究人员和营销从业者提供了一个程序,以方程的形式,计算指数得分,并提供基于预定义的间隔分割市场的规则。因此,在独立的未来研究中复制片段形成的挑战得到了解决。

Online servicescape dimensions as predictors of website trust in the South African domestic airline industry 在线服务逃避维度作为南非国内航空业网站信任的预测因子

Increased costs, competition and a dynamic environment have led to South African domestic airlines relying more on their own websites as outlets for airline tickets. Customers’ e-commerce uptake with respect to buying airline tickets online has been slow, attributed mostly to a lack of website trust. A well-designed online service scape has been identified as an important contributor to website trust by several authors, but not yet in this particular context or industry. This study investigates the extent to which three online service scape dimensions predict website trust in the South African domestic airline industry. A quantitative and descriptive research design was followed, and 300 responses were collected through self-administered questionnaires from domestic airline passengers who had purchased an airline e-ticket from a website. A multiple regression analysis indicates that online financial security is the best predictor of website trust, followed by layout and functionality and aesthetic appeal. Consequently, it is recommended that South African domestic airlines that wish to cultivate website trust should focus primarily on enhancing the online financial security of their websites, followed by customising the layout and functionality of their websites, and lastly improving aesthetic appeal by increasing the entertainment value of their websites.
成本增加、竞争激烈和充满活力的环境导致南非国内航空公司更多地依赖自己的网站作为机票销售渠道。消费者在网上购买机票方面对电子商务的接受速度很慢,主要原因是缺乏对网站的信任。一个设计良好的在线服务场景已经被一些作者确定为网站信任的重要贡献者,但在这个特定的环境或行业中还没有。本研究调查了南非国内航空公司的三个在线服务景观维度对网站信任的预测程度。采用定量和描述性的研究设计,收集了300份从网站购买航空公司电子机票的国内航空公司乘客的自填问卷。多元回归分析表明,在线金融安全是网站信任的最佳预测因素,其次是布局和功能以及美观性。因此,我们建议南非国内航空公司如果希望培养网站信任,首先应该注重提高网站的在线财务安全性,其次是定制网站的布局和功能,最后通过增加网站的娱乐价值来提高审美吸引力。

The purpose of this research was to determine the motives of attendees to Cirque du Soleil’s Dralion production in a developing country. The results revealed five key motives, namely uniqueness, enchantment and aesthetics, fun and entertainment, socialisation and social status and act affiliation. Clustering based on these motives revealed three distinct clusters namely Enthusiasts, Novices and Observers. These clusters show that attendees are not homogeneous in terms of their socio-demographic and behavioural profiles. While the Enthusiasts and Observers displayed similar characteristics to other clusters found in previous research, this research made a clear contribution in identifying Novices as a new emerging segment and suggesting the implications of retaining and expanding this market. The findings of this research can greatly assist marketers of these types of production to expand interest in the arts and increase accessibility to a larger audience.
本研究的目的是确定在发展中国家观看太阳马戏《龙》演出的观众的动机。结果揭示了五个主要动机,即独特性、魅力和美学、乐趣和娱乐、社交和社会地位以及行为归属。基于这些动机的聚类揭示了三个不同的集群,即爱好者、新手和观察者。这些集群表明,与会者在其社会人口和行为概况方面并不相同。虽然发烧友和观察者与之前的研究中发现的其他群体表现出相似的特征,但这项研究在确定新手是一个新兴的细分市场方面做出了明确的贡献,并提出了保留和扩大这个市场的建议。这项研究的发现可以极大地帮助这些类型的生产营销人员扩大对艺术的兴趣,并增加更多的观众的可访问性。

It has been suggested in previous research that it might be worthwhile to include risk measures in the balanced scorecard (BSC) or to rework it in order to manage risk. The literature review in this study indicated that some conceptual and case study research has been done to investigate how an organisation could go about accomplishing this. A number of researchers noted that including risk measures on the face of the scorecard might lead to a problem of over-complexity. Using content analysis as the method of inquiry, this study explored how organisations are currently adding risk to their scorecards. The key fi nding of the study was that organisations that have reported adding risk measures to their BSCs are predominantly adding risk measures to the face of their scorecards. This fi nding is interesting because it would indicate that the previously reported and conceptualised problem of complexity does not seem to have such a great impact as previously thought.
在之前的研究中已经提出,在平衡计分卡(BSC)中包含风险度量或重新设计它以管理风险可能是值得的。本研究的文献综述表明,已经进行了一些概念和案例研究,以调查组织如何实现这一目标。许多研究人员指出,在记分卡上包含风险度量可能会导致过度复杂的问题。使用内容分析作为查询方法,本研究探讨了组织目前如何将风险添加到记分卡中。该研究的主要发现是,报告在其bsc中添加风险度量的组织主要是在记分卡中添加风险度量。这一发现很有趣,因为它表明,之前报道和概念化的复杂性问题似乎并不像之前认为的那样具有如此大的影响。

ABC implementation in the Nelson Mandela Bay Metropole: How far should manufacturing organisations go? 在纳尔逊曼德拉湾大都会实施ABC:制造组织应该走多远?

Activity-based costing (ABC) success factors have been studied in past research, mostly by using commonly known success factors. In this qualitative study, a literature review and interviews were used to establish what factors are responsible for the successful implementation of ABC. The number of semi-structured interviews was limited to 13 ABC adopters in the Nelson Mandela Bay Metropole. The findings suggested that ABC can be enhanced with the use of activity-based budgeting (ABB) and activity-based management (ABM). In addition, the use of ABC in conjunction with capital investment decisions may ensure that correct decisions are made when critical long-term projects are considered. Extensive identification of cost drivers is beneficial to the extent where the product loses its relationship with the overhead cost. It is evident from this research that considering fixed indirect overheads in ABC is not always beneficial for a manufacturing organisation unless there is a clear link to the end-product.
在过去的研究中,对作业成本法的成功因素进行了研究,主要是使用众所周知的成功因素。在本定性研究中,采用文献综述和访谈来确定哪些因素对ABC的成功实施负责。在纳尔逊曼德拉湾大都会,半结构化访谈的数量仅限于13名ABC采用者。研究结果表明,作业成本可以通过使用作业预算(ABB)和作业管理(ABM)来提高。此外,将ABC与资本投资决策结合起来使用,可以确保在考虑关键的长期项目时做出正确的决策。在产品与间接成本失去关系的情况下,广泛识别成本驱动因素是有益的。从这项研究中可以明显看出,除非与最终产品有明确的联系,否则在ABC中考虑固定的间接管理费用并不总是对制造组织有益。

The quality of reported earnings and the monitoring role of the board: Evidence from small and medium companies 报告盈余的质量和董事会的监督作用:来自中小公司的证据
IF 0.6 Q3 LAW Pub Date : 2019-02-26 DOI: 10.25159/1998-8125/5804

The purpose of this paper is to investigate whether corporate governance initiatives in South Africa that relate to the monitoring ability of the non-executive directors on the board of small and medium companies have improved earnings quality by adopting conservative accounting practices. The sample construct includes the 2008 – 2011 reporting periods of South African companies listed on the Alternative Exchange (AltX). A reverse regression of earnings on returns was used to examine the market-based attributes of earnings quality, i.e. conservatism and the timeliness of earnings. No evidence was found that the boards of small and medium-sized companies are inclined to adopt conservative accounting practices that will result in the asymmetric timeliness of earnings. There is also no evidence that the quality of reported earnings improved as a result of the monitoring ability of the board with reference to the representation of non-executive directors on the board. The findings can be of interest to investors, managers and regulators as the efficiency of corporate boards and the transparency of financial reporting have implications for all of them.
本文的目的是调查南非的公司治理举措是否与中小公司董事会非执行董事的监督能力有关,通过采用保守会计实践提高了盈余质量。样本结构包括2008 - 2011年在另类交易所(AltX)上市的南非公司的报告期。收益对收益的反向回归用于检验盈余质量的市场化属性,即稳健性和盈余的及时性。没有证据表明中小企业董事会倾向于采用保守的会计实务,从而导致盈余的不对称及时性。也没有证据表明,董事会对非执行董事在董事会中的代表性的监督能力提高了报告收益的质量。这些发现可能会引起投资者、管理者和监管机构的兴趣,因为公司董事会的效率和财务报告的透明度对他们所有人都有影响。
