Major changes of an aircraft configuration are conducted during the early design stage. It is important to include the airworthiness regulations at this stage while there is extensive freedom for designing. The purpose of this paper is to introduce an efficient design framework that integrates airworthiness guidelines and documentation at the early design stage.

A new design and optimization process is proposed that logically includes the airworthiness regulations as design parameters and constraints by constructing a certification database. The design framework comprises requirements analysis, preliminary sizing, conceptual design synthesis and loads analysis. A design certification relation table (DCRT) describes the legal regulations in terms of parameters and values suitable for use in design optimization.

The developed framework has been validated and demonstrated for the design of a Federal Aviation Regulations (FAR) 23 four-seater small aircraft. The validation results show an acceptable level of accuracy to be applied during the early design stage. The total mass minimization problem has been successfully solved while satisfying all the design requirements and certification constraints specified in the DCRT. Moreover, successful compliance with FAR 23 subpart C is demonstrated. The proposed method is a useful tool for design optimization and compliance verifications during the early stages of aircraft development.

The new certification database proposed in this research makes it simpler for engineers to access a large amount of legal documentation related to airworthiness regulations and provides a link between the regulation text and actual design parameters and their bounds.

The proposed design optimization framework integrates the certification database that is built of several types of legal documents such as regulations, advisory circulars and standards. The Engineering Requirements and Guide summarizes all the documents and design requirements into a single document. The DCRT is created as a summary table that indicates the design parameters affected by a given regulation(s), the design stage at which the parameter can be evaluated and its value bounds. The introduction of the certification database into the design optimization framework significantly reduces the engineer’s load related for airworthiness regulations.

The purpose of this paper is to identify the critical factors (CFs) of ISO 14000; to determine if ISO 14000 certification results in improved organizational performance; and to analyze the levels of and changes in these CFs and levels of and changes in the indicators of organizational performance (IOPs) in relation to firm attributes considered in the present study.

The study employs questionnaire‐survey approach to obtain the practitioners' perceptions of ISO 14000 certification, levels of presence of CFs and changes in CFs due to certification, levels of presence of IOPs and changes in IOPs due to certification. The data collected have been analyzed by using statistical techniques.

The firms regard the preparation for emergencies as an integral part of environmental management system (EMS), and they seem to initially struggle to identify environmental issues that are to be given higher importance. Further, the certified firms find it difficult to continuously improve their environmental management processes. There are significant changes in all the CFs and IOPs due to ISO 14000 certification. Furthermore, more‐experienced firms have higher mean values of levels of all CFs, in comparison with less‐experienced firms. In the course of time, these firms appear to understand the EMS and effectively implement it in order to realize long‐term benefits.

Results of the study are dependent on the nature and number of respondents, i.e. on the perceptions of the top management responsible for quality certification, and the sample size (number of respondents in the current study is 36 due to limited response rate and other operational constraints).

The present study would enable the practitioners to benchmark their organizations (in respect of levels of presence of CFs and levels of presence of IOPs) with those of their competitors, with the best‐in‐class, and also with the industry's mean level. The study also enables one to compare different categories of firms (e.g. firms with low, medium and high levels of turnover; national and international firms; etc.). Since, there is a significant improvement in the organizational performance due to certification, the study provides a strong empirical justification for non‐certified firms to go in for ISO 14000 certification.

The study conceptualizes ISO 14000 as a seven dimensional framework. Further, it has also identified several IOP related to ISO 14000 certified firms. A questionnaire has been developed to obtain the perceptions of top management about the ISO 14000 certification and related factors and indicators; the proposed instrument can be used for several purposes such as functional benchmarking.

The purpose of this paper is to examine the certification and monitoring motivations of third-party underwriting and its effects on credit spreads and earnings management of bank issuers.

Ordinary least squares is used to examine the certification and monitoring effects of third-party underwriting. Furthermore, the Heckman two-stage estimation method is used in controlling the endogeneity of sample selection.

The authors find that financial bonds underwritten by third-party underwriters bear lower credit spreads due to their credibly ex ante certification and effectively ex post monitoring compared with self-underwriting. Moreover, the certification of third-party underwriters can help to select good quality bond issuers with lower earnings management, and the monitoring function also plays an essential role in constraining the behavior of earnings management after the bond issues.

The findings in this study suggest that underwriting types (third-party underwriting) will affect financial bond yields and bank issuers’ earnings management.

On the one hand, the authors should encourage third-party underwriters to actively promote the certification and monitoring functions. For example, given commercial banks the chance to be underwriters when the bond issuers are investment banks, which is not allowed now in China’s financial bond market. On the other hand, the authors should cut off the quid pro quo relations within third-party underwriting because such relations will reduce the certification and monitoring effects of third-party underwriters.

This is the first study to distinguish the certification and monitoring effects by using unique data from China’s financial bond market. And the authors further investigate the adverse effects of quid pro quo relations (hiring each other as lead underwriters) on the certification and monitoring effects of third-party underwriters.

ISO 9000 certification serves as an entré into the global marketplace. European firms have been the most prolific in obtaining ISO 9000 certification. The certification experiences of 11 European firms are described. On‐site interviews and questionnaires were used to identify: the obstacles encountered during the implementation effort; the impacts certification had on operational factors; and the ISO 9000 elements requiring the greatest resources. Results suggest that firms of different sizes, in different industries, in different countries have similar experiences with respect to the obstacles, benefits, and effort associated with ISO 9000 certification. This information may facilitate certification by companies in countries seeking to penetrate international markets.

This study aims to explore the effects of the COVID-19 outbreak on exports of goods and services, logistics performance, environmental management system (ISO 14001) certification and quality management system (ISO 9001) certification in top affected Asian countries of India, Iran, Indonesia, Philippines, Bangladesh and Pakistan.

A novel grey relational analysis models’ approach is used to examine the inter-relationship between COVID-19 economic growth and environmental performance. Moreover, the authors applied a conservative (maximin) model to investigate which countries have the least intensifying affected among all of the top affected COVID-19 Asian countries based on the SS degree of grey relation values. The data used in this study was collected from multiple databases during 2020 for analysis.

Results indicate that the severity of COVID-19 shows a strong negative association and influence of COVID-19 on the exportation of goods and services, logistics performance, ISO 9001 and ISO 14001 certifications in all the six highly affected countries during a pandemic outbreak. Although the adverse effects of COVID-19 in exporting countries persisted until December 31, 2020, their magnitude decreased over time in Indonesia and Pakistan. During the COVID-19 outbreak, Pakistan showed comparatively better performance among the six top highly affected Asian countries due to its smart locked down strategy and prevents its economy from severe damages. While India and Iran export drastically go down due to a rapid increase in the number of COVID-19 cases and deaths.

The research findings produce much-required policy suggestions for leaders, world agencies and governments to take corrective measures on an emergent basis to prevent the economies from more damages and improve their logistics, environmental and quality performance during the pandemic of COVID-19.

This study develops a framework and investigates the intensifying effects of COVID-19 effects on economic growth, logistics performance, environmental performance and quality production processes.

The aim of this paper is to explore interactions between change and stability during the implementation of a specific change initiative (ISO 9000). It attempts to develop a theoretical framework on change and stability management in small firms.

This research uses a process approach based on retrospective comparative case study methodology. Data collection in the six companies lasted over a year. This gives the opportunity to contrast failed change initiatives against successful ones.

Two models emerged from this approach; they support the notion that change and stability could be complementary during the different phases of the change initiative the authors analyzed. The findings show that total absence of stability variables in the change initiative could have negative effect on results.

The research is based on a multiple case study approach, which limits the generalizability of the findings.

This is one of the first studies that applies and empirically tests the change and stability relation in small firms.

The purpose of this paper is to explore the nature of ISO 9001 certification and diffusion in the USA in relation to organizational supply chain position, quality maturity, and supplier quality maturity.

Data for comparison in this study comes from an e-mail survey questionnaire of supply chain professionals across the USA. A pilot survey was initially e-mailed to 100 supply chain professionals and preliminary data from 27 respondents were used to revise the questionnaire. Respondents to the revised questionnaire returned 565 e-mailed questionnaires out of 2,924 active e-mail addresses.

The results suggest that companies adopting ISO 9001 are likely doing so as part of an overall quality management program more so than from direct market pressure. It appears that ISO 9001 certification rates differ by organizational position in the supply chain. ISO 9001 certified organizations are more likely to have quality programs of greater maturity and suppliers with greater quality maturity than organizations that are not ISO 9001 certified. Certified organizations are also more likely to use suppliers that are ISO 9001 capable or certified than non-ISO 9001 organizations.

Not all industry groups or supply chain positions were well-represented due to some small sub-group sizes.

The study of ISO 9001 certification in US organizations has been lacking in the literature. Given the weak adoption rate of ISO 9001 in the USA, this study helps characterize ISO 9001 certification from a supply chain perspective and explores possible reasons for low certification rates.

This research extends the knowledge of quality management in the supply chain by studying ISO 9001 certification in relation to supply chain position and differences in quality maturity between certified and non-certified organizations in the USA.

Rating tools for the built environment were designed to engage consumers and enhance sustainability and resilience. However, the intended outcomes of these rating systems appear to have limited implementation in the residential new housing market in Australia. The purpose of this paper is to investigate consumers’ motivations and experiences who have purchased houses that are situated in a sustainability-based certified development and will have been required to comply with mandatory dwelling certification.

The paper explores the awareness and perception of sustainability ratings and whether the motivations for purchasing in the sustainably certified development have heightened their awareness of sustainability and the resilience of new housing. This has been investigated through a pilot study of consumers who have purchased land in a certified estate and built a new home, through an online survey.

The findings reveal that the rating systems are at present not having the desired influence as first thought; that is, to inform consumers of the sustainability of a dwelling or property and to instigate trust of the environmental credentials of the property.

This illuminating case study of participants who have purchased a sustainable rated development demonstrates that regardless of their concern for environmental issues, consumers have both low awareness and trust in the ratings. Despite this, consumers do seek value from these credentials to the overall property.

This study aims to illustrate the disconnect in engagement between developers, builders and new home buyers in relation to sustainability certification and implementation.

This is a longitudinal study exploring the effect of ISO 9000 certification on firm's financial performance in the pre-crisis period and the 2008 financial crisis period.

The empirical analysis is based on a 22-year dataset with balance sheet data from 136 Greek listed firms covering the period 1992–2013. A matching technique is applied to properly estimate potential differences in the impact of ISO 9000 on firm's financial performance between the groups of certified and matched non-certified (control) firms in the entire period but, most importantly, in pre-crisis vs crisis periods, using the difference-in-differences econometric approach.

The findings indicate that certified firms exhibit significantly higher financial performance relative to the matched non-certified group in both the pre-crisis and crisis periods, which tends to persist for several years post-certification. The financial crisis has a negative and statistically significant effect on firm performance in both the certified and matched non-certified groups, which nevertheless did not differ significantly between them. Controlling for sectoral and technological differences did not harm the higher performance of certified firms relative to the matched control peers. The results remain in the same direction when the authors test the ISO 9000 effect in the sub-group of certified firms that obtained the certification at the firm-level.

The study is original in its sample design and hypothesis testing. The matched sample created from a sufficiently long and continuous time dataset enabled the authors to properly estimate firm performance differences of ISO 9000 between pre-crisis and crisis periods. Of additional value is the testing of sectoral/technological differences and the distinction between firm-level and plant-level certification.

Consumers often face a dilemma regarding the purchase decisions of traditional handloom apparel because of the non-availability of information cues that would enable them to assess the quality of the product. The spread of counterfeit products in the market adds to information asymmetry. The study aims to examine factors influencing purchase intention of traditional handloom apparel that have Geographical Indication (GI) certification, which follows the certification procedure specified by the World Intellectual Property Organisation (WIPO).

A survey was conducted among 202 traditional handloom apparel consumers in India and the data was analysed using structural equation modelling. The purchase intention of GI certified handloom apparels was examined as the dependent variable, whereas quality consciousness, product diagnosticity, perceived information asymmetry were placed as independent variables. The mediating role of perceived quality and product trust in the relation between perceived information asymmetry and purchase intention was also looked into.

Results reveal that quality consciousness positively influences product diagnosticity (facilitated by the GI label certification) which in turn reduces perceived information asymmetry. Further, a reduction in perceived information asymmetry was found to increase the purchase intention of traditional handloom apparel, fully mediated by the perceived quality and product trust.

The customers who are facing a dearth of information while making purchase of traditional handlooms will be benefitted from the GI certification label which provides authenticity regarding product attributes confirming quality. Further, the study adds to the theory by establishing the relation between quality consciousness and perceived information asymmetry.

The findings imply that GI handloom apparel sellers should design marketing strategies that would project GI certification labels for traditional handloom apparel to effectively communicate product quality attributes, thus enhance product diagnosticity reducing information asymmetry. While organic certification for agricultural products is done at the individual producer’s level, GI certification is done under the producer’s collective label. Further, studies may be extended to agricultural products (Darjeeling tea, Alphonso mangoes, etc.), food items (rasgulla, Thirupathi laddoo, etc.) and handicrafts (Aranmula Mirror, Payyannur pavithra ring) that have acquired GI label in India. GI certification is adopted worldwide and studies may be extended to such products also [example Parma ham (Italy), Hessian wine (Germany)].

Empirical research on determinants of consumer purchase intentions of GI certified traditional handloom apparel is a novel attempt done in the context of a developing country such as India. The study brings out the importance of the GI certification label envisaged by the WIPO, which can serve as a tool for reducing uncertainties faced by consumer in framing purchasing intentions. This can be extended to any product type such as agricultural, food products and handicrafts that has acquired GI certifications in different countries. The study revealed that product diagnosticity (through GI certification) could reduce perceived information asymmetry that leads the consumer to the perception of quality and product trust which results in the purchase intention of traditional handloom apparel. The outcomes of the study can be instrumental in designing marketing strategies for capturing market share.
