The purpose of this study is to investigate the microstructural evolution of high-strength 2024 Al alloy prepared by the laser powder bed fusion (L-PBF) additive manufacturing (AM) route. The high-strength wrought Al alloy has typically been unsuitable for AM due to its particular solidification characteristics such as hot cracking, porosity and columnar grain growth.

In this research work, samples were fabricated using L-PBF under various laser energy densities by varying laser power and scan speed. The microstructural features that developed during the solidification are correlated with operating laser parameters. In addition, finite element modelling (FEM) was performed to understand the experimentally observed results.

Microstructure evolution and defect formation have been assessed, quantified and correlated with operating laser parameters. Thermal behaviour of samples was predicted using FEM to support experimental observations. An optimised combination of intermediate laser power and scan speed produced the least defects. Higher energy density increased hot tearing along the columnar grain boundaries, while lower energy density promoted void formation. From the quantitative results, it is evident that with increasing energy density, both the top surface and side wall roughness initially reduced till a minimum and then increased. Hardness and compressive strength were found to decrease with increasing power density due to stress relaxation from hot tearing.

This research work examined how L-PBF processing conditions influence the microstructure, defects, surface roughness and mechanical properties. The results indicates that complete elimination of solidification cracks can be only achieved by combining process optimisation and possible grain refining strategies.

The chapter aims to examine the interrelationships between aviation and Asian inbound tourism demand to Australia. First, the chapter introduces key factors in the economics of tourism demand and the empirical work in assessing the aviation–tourism demand relations. Based on 2005–2016 annual time series data across 12 of Australia’s main Asian markets, a dynamic panel regression model is applied to empirically examine the factors influencing tourism demand including exchange rates and disposable income. Using a generalized method of moments approach, the study accounts for the endogenous relations between levels of international air services availability (proxied by seat capacity) and tourism demand. The results suggest, on average, the generative effect of aviation exists albeit with small magnitude (0.1–0.5% increase in tourism demand per 100,000 additional seat capacity). The chapter concludes with a discussion on the shifting inbound tourism balance toward Asia and the implications for aviation policy to meet the high Asian tourism growth targets.

The authors passively apply a researcher profile pitch (RPP) template tool in accounting and across a range of Business School disciplines.

The authors document a diversity of worked examples of the RPP. Using an auto-ethnographic research design, each showcased researcher reflects on the exercise, highlighting nuanced perspectives drawn from their experience. Collectively, these examples and associated independent narratives allow the authors to identify common themes that provide informative insights to potential users.

First, the RPP tool is helpful for accounting scholars to portray their essential research stream. Moreover, the tool proved universally meaningful and applicable irrespective of research discipline or research experience. Second, it offers a distinct advantage over existing popular research profile platforms, because it demands a focused “less”, that delivers a meaningful “more”. Further, the conciseness of the RPP design makes it readily amenable to iteration and dynamism. Third, the authors have identified specific situations of added value, e.g. initiating research collaborations and academic job market preparation.

The RPP tool can provide the basis for developing a scalable interactive researcher exchange platform.

The authors argue that the RPP tool potentially adds meaningful incremental value relative to existing popular platforms for gaining researcher visibility. This additional value derives from the systematic RPP format, combined with the benefit of easy familiarity and strong emphasis on succinctness. Additionally, the authors argue that the RPP adds a depth of nuanced novel information often not contained in other platforms, e.g. around the dimensions of “data” and “tools”. Further, the RPP gives the researcher a “personality”, most notably through the dimensions of “contribution” and “other considerations”.

Discusses the virtues of creativity as the first part of a process enabling companies to outperform their competitors. Considers five techniques for stimulating creativity, with examples of applications of each: lateral thinking, metaphoric thinking, positive thinking, association trigger, and capturing and interpreting dreams. Surmises that creative thinking relies on practice and the right environment as well as education in techniques.

As a “fictitious commodity” (Polanyi), that cannot be separated from the human being who is its owner, labor has a special moral significance. However, this moral quality is not a given but must be asserted in struggles over the value of labor. With the example of disabled workers in Switzerland, this chapter examines the moralization of labor as a means to revalue a category of workers who range far down the labor queue. Moralization mediates the tension between the normative societal goal of inclusion for disabled people and the freedom of employers to select the most “productive” workers. Drawing on the theoretical approach of the Economics of Convention the chapter analyzes the valuation frames proposed by economic and welfare state actors in political debates over the establishment of the Swiss disability insurance and the role of employers regarding occupational integration. A core concept used in negotiations of the value of disabled labor in the public arena and within individual businesses is the “social responsibility” of employers. Historically, employers’ associations successfully promoted the liberal principle of voluntary responsibility to prevent state interference in the labor market. In contrast, disability insurance argues predominantly within the market and the industrial convention to “sell” its clientele in the context of employer campaigns and case-related interactions with employers. Only recently, both sides started to reframe the employment of disabled people as a win–win affair, which would reconcile economic self-interest and the common good.
