Mapping domain characteristics influencing Analytics initiatives: The example of Supply Chain Analytics

Purpose: Analytics research is increasingly divided by the domains Analytics is applied to. Literature offers little understanding whether aspects such as success factors, barriers and management of Analytics must be investigated domain-specific, while the execution of Analytics initiatives is similar across domains and similar issues occur. This article investigates characteristics of the execution of Analytics initiatives that are distinct in domains and can guide future research collaboration and focus. The research was conducted on the example of Logistics and Supply Chain Management and the respective domain-specific Analytics subfield of Supply Chain Analytics. The field of Logistics and Supply Chain Management has been recognized as early adopter of Analytics but has retracted to a midfield position comparing different domains. Design/methodology/approach: This research uses Grounded Theory based on 12 semi-structured Interviews creating a map of domain characteristics based of the paradigm scheme of Strauss and Corbin. Findings: A total of 34 characteristics of Analytics initiatives that distinguish domains in the execution of initiatives were identified, which are mapped and explained. As a blueprint for further research, the domain-specifics of Logistics and Supply Chain Management are presented and discussed. Originality/value: The results of this research stimulates cross domain research on Analytics issues and prompt research on the identified characteristics with broader understanding of the impact on Analytics initiatives. The also describe the status-quo of Analytics. Further, results help managers control the environment of initiatives and design more successful initiatives.DFG, 414044773, Open Access Publizieren 2019 - 2020 / Technische Universität Berli

Global Account Management for Sales Organization in Multinational Companies

A Global Company is not just a Multinational Company, but on top it has developed an organizational structure, an overall governance and a set of operational decision making processes which allow running a significant percentage of business processes as a unique body across borders. Successful Global Companies have a clear setup and governance of local versus centralized decision making processes, as well as budget ownership. Corporations focused on global opportunities need to re-think their customer approach, namely in terms of set up of their sales force, and more specifically planning, a transformation from national based to international managed sales organization for those specific customers.Globalisation; Market-Driven Management; Global Companies; Multinational Companies; Vision; Global Account Management; Sales Organization; Management of Change; Corporate Culture; Corporate Responsibility

Haar projection numbers and failure of unconditional convergence in Sobolev spaces

For $1<p<\infty$ we determine the precise range of $L_p$ Sobolev spaces for which the Haar system is an unconditional basis. We also consider the natural extensions to Triebel-Lizorkin spaces and prove upper and lower bounds for norms of projection operators depending on properties of the Haar frequency set

Is the impact of labour taxes on unemployment asymmetric?

This paper tests whether the impact of labour taxes on unemployment is symmetric with respect to increases and decreases in labour taxes. Using a panel of 16 OECD countries over the period 1970-2005, we estimate a panel unobserved component model to account for the fact that unemployment rates and labour taxes are non-stationary but not cointegrated. We find a positive impact of tax increases in European and Nordic countries with some evidence that tax decreases have a more moderate impact. For Anglo-Saxon countries, no impact of labour taxes on unemployment is found
