Abstract
Übergang zur nachgelagerten Rentenbesteuerung bewirkt keine Doppel, sondern eine Minderbesteuerung, was gleichbedeutend mit einer Steuervergünstigung für Bezieher gesetzlicher Renten ist. Dies gilt zumindest dann, wenn man dem Ansatz der Rürup-Kommission und des Gesetzgebers folgt, was die Zurechnung von sozialversicherungsinduzierten Sonderausgaben in der Beitrags- und in der Rentenphase anbelangt. Das Ausmaß der Minderbesteuerung hängt von der zukünftigen Rentenentwicklung, aber auch vom verwendeten Maßstab ab. Nach dem in der Recht-sprechung und Literatur regelmäßig verwendeten (Literatur-)Maßstab beläuft sich die Minderbesteuerung einzelveranlagter Arbeitnehmer im derzeitigen Recht auf durchschnittlich rund 11,9 % der Renten, während die Minderbesteuerung bei „systemgerechter“ Analyse bei rund 8,4 % liegt. Durch eine immer noch pauschalierte, aber passgenauere Besteuerung gesetzlicher Renten ließe sich die Minderbesteuerung erheblich reduzieren, ohne Doppelbesteuerungsprobleme in Kauf nehmen zu müssen. Eine am systemgerechten Maßstab ausgerichtete Reform ist unempfindlich gegenüber der Rentenentwicklung, während die Besteuerungsanteile der gesetzlichen Rente im Fall einer auf dem Literaturmaßstab basierenden Reform immer anzupassen sind, sobald sich Renten anders entwickeln als ursprünglich prognostiziert.

Abstract
In today’s business, it is largely acknowledged that sustainability has to be considered in managerial decision making and corporate strategy development. However, many firms still face substantial operational and organizational challenges when striving for a transformation toward sustainability, especially when expanding their efforts toward their supplier base. Framed by the recently emerging theoretical lens of the practice-based view and its extension toward the supply chain practice view, and grounded in recent conceptualizations of sustainable supply chain management, the study at hand elaborates on management practices by which firms can improve the sustainability of their supply chains. Due to its high economic relevance and its exposure to increasing sustainability requirements, the chemical process industry is chosen as the empirical research field. Qualitative case study research identifies intra- and inter-organizational practices that are important to achieve and improve supply chain sustainability. A framework that conceptualizes sustainability practices and their implementation prerequisites and performance impacts is derived from interviews with key informants from German chemical manufacturers. This paper contributes to the state-of-the-art of sustainability diffusion in particular through its distinct focus on imitable practices that are easily transferable between companies and hence may help in transforming entire industry sectors toward sustainability.

Abstract
Sustainable operations and sustainable supply chain management (SSCM) have become a highly relevant topic for scientific research and management, as well as policy-making practice. Despite surging growth in extant research, the need for theoretical and conceptual substantiation persists, and large opportunities for further research remain unexploited. This paper responds to the need for a conceptual foundation and, therefore, aims at providing a structured agenda for future research areas in SSCM. Based on an abductive reasoning approach, SSCM constructs and concepts are gathered from existing literature and recombined into a comprehensive conceptual SSCM framework. Areas and directions for future SSCM research, as suggested in earlier studies, are summarized, positioned in the framework, and outlined to stimulate further SSCM research activities. To overcome the lack of holistic research in the field, sophisticated techniques and integrated systems to support decision-making are required to tackle related issues’ complexity. Therefore, this paper’s contribution lies in the synthesis of state-of-the-art literature to provide a more comprehensive view of SSCM. Researchers may find promising recommendations and a suitable foundation for future studies, while practitioners may find helpful orientation and guidance for decision- and policy-making.
