Abstract

Purpose

This paper aims to propose a method to automate the tolerance analyses of mechanical assembly using STandard for the Exchange of Product model data-Application Protocol Part 242 (STEP AP 242) files derived from the 3-D computer-aided design (CAD) models.

Design/methodology/approach

Product manufacturing information and mating information available in ISO 10303 STEP AP242 files resulting from the 3-D CAD model of mechanical assembly are extracted. The extracted geometric attributes, geometric dimensioning and tolerancing (GD&T) and mating information are used to automatically generate assembly graph and mating edges required for the tolerance analyses of the mechanical assembly by using the matrix approach.

Findings

The feasibility of the proposed method is verified through two mechanical assembly case studies. The results of manual calculations and tolerance values computed by the automated method are very closely matching.

Practical implications

Tolerance analysis is an integral part of product development that directly influences the cost and performance of a product. Apart from the academic interest, the work is expected to have positive implications for the digital design and smart manufacturing industry that involve in the development of solutions for automation of design and manufacturing system functions.

Originality/value

The approach presented in the paper that aids the automation of tolerance analyses of mechanical assembly is an innovative application of the STEP AP 242 file. The automation of tolerance analyses would improve the productivity and efficiency of the product realization process.

Abstract

Purpose

Decision making for acceptance of an R&D project occurs under uncertainty and may involve predominantly quantitative analyses, such as net‐present value, predominantly intuitive analyses, such as real options logic, or some combination thereof. This paper attempts to bring together two concepts of decision theory, i.e. heuristics and framing, and real options logic into one integrated view relative to R&D project valuation. It is believed that the integration of theory helps explain expected and unexpected decisions resulting from the R&D project valuation process.

Design/methodology/approach

It is proposed here that, under a typical R&D project review, aspects of two theoretical concepts integrate to aid project valuation and decision making. The aim of this paper is to develop a research framework leading to advancement in the understanding of the relationship of heuristic principles from decision theory and the valuation methodology of real options logic. Findings – As a conceptual paper, propositions and a research model representing the conceptual framework are presented.

Research limitations/implications

Stemming from the propositions and research model, it is believed that the degree of influence that heuristics potentially exhibit on real options logic can be successfully measured. Confirming the degree of influence is a matter for future empirical research.

Originality/value

The originality of this paper is to develop a research framework leading to advancement in the understanding of the relationship of heuristic principles from decision theory and the valuation methodology of real options logic. In this framework, heuristics has been positioned as a moderator affecting project valuation derived by real options logic.

This instructional tool enhances coverage of statement of cash flows topics in graduate or upper division undergraduate accounting and finance courses.

Abstract

Purpose

This instructional tool enhances coverage of statement of cash flows topics in graduate or upper division undergraduate accounting and finance courses.

Methodology/approach

We review one of the complexities of preparing the statement of cash flows. The exercise may include a discussion of the mechanics of preparation of the statement of cash flows using the indirect method. This discussion might include rationales behind operating section adjustments and highlight the pitfalls of using these adjustments without understanding their reasons. Preparation of a statement of cash flows may be followed by introducing the concept of nonarticulation and how it can cause the information presented in the statement to be misleading. To further understanding, the instructor may introduce the reconciliation worksheet provided. Finally, a current public company example, also provided, highlights the magnitude of nonarticulation in practice.

Findings/practical implications

Students learn the complexities related to the preparation of the statement of cash flows. They are introduced to the concept of nonarticulation using an example of public company financial statements. Student feedback suggests appreciation for developing a deeper understanding of the statement of cash flows, learning why they are unable to replicate disclosed operating cash flow from balance sheets of publicly traded companies.

Abstract

Purpose

The purpose of this paper is to introduce an integrated laboratory experiment setup (ILES) to overcome problems encountered in open distance learning (ODL) especially when offering engineering degree programmes.

Design/methodology/approach

Engineering laboratory experiments can be classified as experiments which are performed with the intention to inculcate theory, and second, to provide hands-on experience. The ILES integrates both types of experiments with face-to-face laboratory (FFL), online remote laboratory (ORL), and multimedia demonstrations, and it helps to reduce traditional FFL duration by 50 per cent. The first phase of the ILES provides an opportunity to refer multimedia demonstrations of the experiments. Thereafter, students attend the first FFL session, which covers about 25 per cent of the experiments. In the next step, 50 per cent of the experiments are offered using the ORL, via the internet while interacting with real equipment and making actual observations. The final step is used to accomplish the rest of the experiments (25 per cent) in FFL which facilitates the clarification of any problem that may occur in the ORL.

Findings

This blended laboratory system will help to achieve ODL objectives while utilising resources productively and cost effectively. Having implemented the idea and based on the information received from the stakeholders, this has proved to be a workable solution to one of the difficulties faced by ODL students.

Research limitations/implications

The level of outcome of the students has to be observed and analysed in comparison with the traditional laboratory setup.

Practical implications

Some experiments (e.g. thermodynamics) which need more safety precautions are difficult to offer via ORL.

Originality/value

The ILES is a blended setup including FFL, ORL and multimedia demonstrations and it is a novel concept which is most applicable to engineering/science programmes offered in ODL mode.

Abstract

Purpose

The purpose of this paper is to examine whether the gender of the top executives is associated with the strength of corporate governance mechanisms within a firm.

Design/methodology/approach

The paper uses panel and instrumental variable regressions on an eight-year sample of the S&P 1,500 firms.

Findings

The results indicate that firms with female Chief Executive Officers (CEOs) and Chief Financial Officers have higher quality governance practices. Moreover, female CEOs are documented to have the most significant influence on the governance attributes related to the board of directors and takeover defenses mechanisms.

Originality/value

Overall, these findings indicate that the gender of the firm’s executives may have important implications for the strength of corporate governance. The paper promotes the importance of the recent national policies in numerous countries on gender quotas at the executive level.

Abstract

Purpose

The purpose of this paper is to investigate whether investors prefer stocks with more linguistically fluent tickers (MAK, SOM) to those with less linguistically fluent tickers (WQH, JZU) in an experimental setting.

Design/methodology/approach

The author conducts an experiment in which a choice of two hypothetical investments with linguistically fluent and non-fluent tickers is presented to survey participants, who are asked to choose the preferred investment (or indicate that they are indifferent between the investments).

Findings

Consistent with investor rationality, survey results indicate that, for both riskless and risky investments, individuals do not exhibit differential preferences for stocks with pronounceable vs unpronounceable tickers. Additionally, individuals are not willing to pay more for former vs latter stocks.

Originality/value

A potential implication is that corporate boards should not attribute high importance to ticker fluency.
