This paper aims to investigate the mechanical (tensile, hardness, impact, elongation), microstructure and wear behaviours of aluminium alloy reinforced with mussel shell powder (MSP) at different weight percentages (0 wt. % to 15 wt. %) at 3 wt. % interval. The mussel shell powder was characterized by X-ray fluorescence (XRF). The matrix and the composites’ morphology were studied using a scanning electron microscope attached with energy dispersive spectroscopy for the distribution of mussel shell powder particles within the matrix. The wear behaviour of the alloy and composites produced at various reinforcements were carried out using a Taber abrasion wear-testing machine. The XRF showed the compositions of MSP to contain calcium oxide (95.70 %), silica (0.83 %) and others. Mechanical properties showed that tensile values increase with increases in MSP, hardness value increases from 6 wt. % to 15 wt. % of MSP. The impact energy decreased from 42.6 J at 3 wt. % to 22.6 J at 15 wt. %; the percentage elongation also decreased from 37.4 % at 3 wt. % to 20.5 % at 15 wt. % MSP, respectively. The bending stress results increase with increases in the percentage of reinforcement. The morphologies revealed that uniform distribution of MSP within the matrix resulted to improvement in mechanical properties. The wear resistance of the composites increases with increase in the applied load and decreases with increases in the weight percentage of MSP and can be used in the production of brake pads and insulators in the automobile industry.

The industrial policy in the UK and in Portugal, as in most EU countries, seeks to attract new investment capacity, to create jobs and to promote the impact of the so-called "demonstration efect" of "greenfield" development strategies pursued in the new plants of inward investors on existing or "brownfield" plants. This industrial policy focus is particularly evident in the automobile industry.This paper compares the industrial policy oriented towards the automobile industry in the UK and in Portugal. Two recent "greenfield" investments are analised: Nissan in the North-East region (UK) and Ford/VW in the Setúbal Peninsula (Portugal), as well as three "brownfield" plants: Ford Halewood and GM Vauxhall Ellesmere Port in the North-West region (UK) and Renault in Setúbal (Portugal). The first part starts with a discussion of industrial policy in the automobile sector, the role of "greenfield" development strategies and the "demonstration effect" on "brownfield" plants. Then, the limits of new inward investment are pointed out, basically their problems and restrictions. Afterwards, the structural barriers to the "demonstration effect" within "brownfield" plants are outlined and some possabilities for alternative "brownfield" development strategies are presented.

Purpose The purpose of this paper is to discuss the corporate behavior of Volkswagen in its emissions scandal. It describes and analyzes a complex ethics dilemma within the purview of corporate social responsibility (CSR) and corporate sustainability (CS) and examines how this dilemma impacts critical stakeholders, thus offering several “opportunities to learn” for professionals. Design/methodology/approach The case takes a stakeholder perspective, applying Cavanagh et al. (1981) and Gao’s (2008) ethical judgement framework. It is situated within a qualitative approach to textual analysis. Social actors, topics and evaluative statements were identified and grouped into broader categories. Findings Six major stakeholders were directly affected by Volkswagen’s behavior: customers, investors and shareholders, the US Environmental Protection Agency, German authorities, European institutions and society-at-large. Stakeholder concerns were condensed into three dominant themes: economic, legal and environmental. According to the ethical judgment framework, Volkswagen corporate behavior showed ethical problems, theoretically demonstrating that under no ethical principle was Volkswagen’s actions justifiable, even under instrumental justifications. Research limitations/implications The analysis was primarily based on corporate material and news media reporting. Consequently, diverse managers’ prospectives and opinions are not entirely captured. Practical implications This paper offers several “opportunities to learn” for corporate communication professionals. Originality/value The focus on stakeholder perspectives allows professionals to take an outside-in approach when evaluating the impact of corporate actions on stakeholders’ interests. The case analysis through Cavanagh et al. (1981) and Gao’s (2008) ethical judgment framework provides a practical theoretical instrument to assess corporate behaviors that can be used both as pre- and post-evaluations of corporate actions on CSR and CS issues.

This study examines the dynamic relationships between firm-generated content (FGC), user-generated content (UGC), traditional media, and offline light vehicle sales. Data were collected from the official Facebook and Twitter pages of 30 U.S. car brands from 2009 to 2015. Our results suggest that Facebook and Twitter are heterogeneous in terms of their effect on offline vehicle sales; FGC is more effective than UGC for influencing offline light vehicle sales; viral impressions from Facebook and Twitter are essential, although effects vary for the various social media platforms, FGC, and UGC; and a firm’s marketing efforts and UGC both have a long-term effect on sales, with the long-term effect of a firm’s marketing efforts outlasting that of UGC. We also documented the within-Twitter synergistic effect between FGC and UGC for offline car sales and cross-channel substitution relationships between FGC and both Facebook and traditional media and Twitter and traditional media. Our study implies that managers who attempt to maximize multichannel marketing for offline sales of durable goods should consider (1) the nature of each platform, (2) the number of potential audiences each platform can reach, and (3) the user basis of each platform.

This article examines the impact of new product development (NPD) “make/buy” choices on product quality using data from the automobile industry. Although the business press has lamented that NPD outsourcing compromises product quality, there is no systematic evidence to support or refute this assertion. Against this backdrop, this study tests a contingency model of the impact of NPD make/buy decisions on immediate and future product quality. The hypotheses are tested using data on NPD make/buy choices of 173 models of 12 automobile firms in the United States between 2007 and 2014. The authors find that whereas NPD buy has a more positive impact on immediate product quality, NPD make has a more positive impact on future product quality. Furthermore, the immediate product quality impact of NPD buy is stronger when (1) technologies are more complex and (2) firm NPD capability is higher. In contrast, the future product quality impact of NPD make is stronger when (1) there is postlaunch adverse feedback and (2) firm NPD capability is higher. The study highlights the complex trade-offs associated with NPD make/buy decisions and offers valuable insights on how firms could manage these decisions.

The study evaluates the impact of risk on enterprises of male, female and young farmers operating in the formal and informal smallholder dairy value chains in Tanzania. It also examines the effect of uncertainty on the decision to invest in milk production in the two value chains. Results indicate that youths in the informal dairy value chain face the greatest level of risk followed by men in the formal value chain, and then men in the informal value chain. Women in both value chains and youths in the formal value chain face relatively low risk. Overall, milk production in the informal value chain is found to be substantially riskier than production in the formal chain. Optimal investment triggers are found to be much larger than the conventional triggers and are sensitive to volatility of returns. The results’ managerial and policy implications for inclusive dairy industry development in Tanzania are highlighted.
