Australian enrolment trends in technology and engineering: putting the T and E back into school STEM

There has been much political and educational focus on Science, Technology, Engineering and Mathematics (STEM) in Australian schools in recent years and while there has been significant research examining science and mathematics enrolments in senior high school, little is known about the corresponding trends in Technologies and engineering. Understanding these subjects is essential for educators and policy-makers alike if Australians are to embrace the challenges of an innovation economy. We have collected raw enrolment data from each of the Australian state and territory education departments from 1992 to 2014 and analysed this across five Technology and Engineering subject areas. We also consider some of the relationships between these subject areas and other areas of the STEM equation. The results of these analyses are discussed in terms of absolute enrolments, participation rates and sex balance. We have found that the total number of students in Year 12 increased year on year and that this growth is echoed, to a lesser extent, in the participation rates for design technology, food technology and engineering. Digital Technologies however, grew rapidly until 2000, after which time it has been in steady decline. We identify that while the trends mostly show growth, there is a concerning male bias to many of these subject areas. We suggest that the broadening of the upper high school curriculum, confusion surrounding vocational training enrolments, and gamesmanship of the university entrance system, may be contributing to the limited growth observed. Finally, we identify a number of important areas for further research in this key learning area.     

Dividend imputation taxes and the curious case of a price premium between BHP and Billiton American depositary receipts

BHP Group was formed in 2001 when the Broken Hill Proprietary Company Limited in Australia merged with the Anglo–Dutch Billiton Plc in the UK to form a dual−listed company. The American Depositary Receipts (ADRs) for BHP and Billiton trade on the NYSE, and despite these two securities having exactly the same voting rights and US dollar denominated dividends, the BHP ADR generally sells at a premium to the Billiton ADR, though that premium has considerable time−series variation. We investigate whether differences in the imputation tax systems that apply to dividends in Australia and the UK help explain the time series variation in the premium of the ADR prices. Our results confirm that imputation tax differences are a significant determinant of the premium. Our paper hence provides direct evidence that imputation tax credits are capitalised into equity prices.     

Lead independent directors and accruals quality

We investigate the association between firms having a lead independent director (LID) who serves on the audit committee and accruals quality using a sample of 32,346 observations during 2001–2018 period. Our results suggest that firms with an LID who serves on the audit committee are associated with higher accruals quality. The results suggest that these firms are associated with an increase in accruals quality equal to 6.60% of the accruals quality metric's median value. We also find that as board size increases, the positive influence of an LID on accruals quality weakens—but only for firms with an LID who does not serve on the audit committee. Supplemental analyses indicate that our inferences still hold when using a changes model, when examining a firm's initial adoption or elimination of the LID position, and when using an entropy balancing approach.     

Building coalitions on Facebook: ‘social media unionism’ among Danish bike couriers

Platform work represents an important challenge for the ‘Danish model’ of unionisation. Using interviews and ethnographic data, this article analyses the strategies of the Danish grassroots union movement the Wolt Workers' Group, representing principally migrant couriers using the food-delivery platform Wolt. This study is an attempt to map an emergent form of flexible labour organisation based on horizontal, informal online networks while supported in different ways by established unions. We term this strategy of balanced autonomy and support ‘social media unionism'. Wolt couriers' attempts at grassroots organisation via social media is an important and understudied issue, especially their complex relationship to union actors. The ‘social media unionism' explored in this article allows for the formation and maintenance of nimble grassroots mobilisation among workers that are otherwise hard for unions to reach, such as migrants platform workers. We argue that this strategy holds both great possibilities and challenges for the labour movement.
