The impact of working capital management on profitability - a comparative analysis of German and Japanese automotive manufacturers

This study investigates the impact of Working Capital Management (WCM) on profitability by analyzing six years of quarterly data of German and Japanese automotive manufacturers. Descriptive statistics and independent t-tests reveal significant country differences. Japanese companies follow a more aggressive WCM policy, expressed by a significantly lower Cash Conversion Cycle (CCC) and a higher Return on Assets (ROA) than German firms. The results of the correlation analysis and Ordinary Least Squares regressions stress the importance of WCM. Managers of automotive manufacturers can improve ROA by lowering CCC, Days Sales Outstanding, and the share of current assets on total assets

Food and beverage collaboration patterns: a systematic literature review

This paper provides a “state of the art” view of the literature about food and beverage collaboration and pinpoints to new research fields related to collaboration in the Food and Beverage industry. Using a systematic literature review methodology, we identify and summarize the published evidence on collaboration in the Food and Beverage industry and thus synthesize previous work to strengthen the topic of collaboration in the Food and Beverage industry. A total of 228 topic-related articles were retrieved from the databases Scopus and Web of Science. After validation, 46 articles were identified as relevant, accessed and reviewed to understand the significance and the critical role played by collaboration, interaction and partnership among the university, industry and the government. Results indicate that the challenges and problems experienced in the food industry can be addressed through innovation and technological advancement. To achieve open innovation there are key players who must come together and facilitate the entire process. The industry, the university, the government and the consumer need to collaborate to yield positive outcomes. This indicates the significance of collaboration to facilitate open innovation.publishe

Cosmological perturbation theory and quantum gravity

It is shown how cosmological perturbation theory arises from a fully quantized perturbative theory of quantum gravity. Central for the derivation is a non-perturbative concept of gauge-invariant local observables by means of which perturbative invariant expressions of arbitrary order are generated. In particular, in the linearised theory, first order gauge-invariant observables familiar from cosmological perturbation theory are recovered. Explicit expressions of second order quantities are presented as well
