Cost accounting-based assessment of the net social benefit of German waste-to-energy plants under stricter environmental valuation: Public-record evidence from 2017 to 2023

Push notifications are a core functionality of mobile apps and allow app publishers to interact with existing app users and send promotional content. Since every push notification can also interrupt or annoy app users, the frequency of push notifications is a critical success factor. This study investigates how different frequencies of push notifications affect the behavior of app users of mobile apps in retail. In an experiment with 17,500 app users, five different frequencies are tested over seven weeks, and the effects on real observed app user behavior are analyzed. The results show that as the frequency of the non-personalized push notifications increases, uninstalls increase, and the direct open rate of push notifications decreases. A significant influence on indirect opens cannot be proven. The results provide practitioners with important insights into the potential harm that a too high frequency of push notifications can cause. Furthermore, the results support the importance of relevant content tailored to the respective user.

Corporate accelerators are on the rise and established companies from a diverse set of industries and regions have set up such startup support programs to predominantly pursue strategic goals. The purpose of this study is to shed light on the benefits of corporate accelerators from a corporate perspective and that of the participating startups. In order to do so, this in-depth single-site case study investigates the SAP Industry 4.0 Startup Program building upon an inductive research design with explorative nature. The authors qualitatively examine a newly established corporate accelerator program of one of the world’s largest enterprise software companies and provide valuable insights for both practitioners and scholars engaged in corporate accelerators. The benefits for startups participating in corporate accelerator programs can be linked to operational go-to-market acceleration in regards to product development, sales acceleration, as well as skill and knowledge development. Moreover, the startups receive benefits linked to strategic business development acceleration in the areas of strategy and business model improvements, pitching, financing, and strategic partner development. At the same time, corporate accelerators overall aim to increase the competitiveness of established companies running such programs by developing a product ecosystem and the brand, infusing startup culture into the organization and developing customer relationships.

The authors examined environmental responsibility and financial performance nexus of Johannesburg Stock Exchange’s socially responsible investing manufacturing and mining firms during the period of 2008-2014. The study employs annual panel dataset of fourteen manufacturing and mining companies on the index, and Granger causality analysis using Gcause2 Baum’s version. The paper found unidirectional causal relationship between environmental responsibility, measured by emissions intensity and equity returns, and bidirectional causal relationship between emissions intensity and market value of equity deflated by sales at 1% significant levels. Impliedly, improvements in ‘energy efficient technologies’ to reduce fossil energy consumption (prevention activities) seem to exhibit value destroying tendencies, while improvements in ‘end-of-pipe’ activities seem to estimate a drive market value of equity deflated by sales and equity returns. The Pesaran CD and Breusch-Pagan LM tests confirmed existence of cross-sectional dependence amongst panel members. The authors tend to support institutional and stakeholder theories.
