Understanding value creation in closed loop supply chains – Past findings and future directions

The topic of value creation through the recovery of returned products in closed loop supply chains is scattered across various bodies of literature. We undertake a systematic literature review of 144 articles in relevant green, reverse and closed loop supply chain literature to synchronize existing knowledge on value creation. Value manifestations of four types of value, namely economic, environmental, information and customer value, are identified. Value adding concepts from the forward- and reverse supply chain may leverage the process of value creation. They are classified into six subclasses, namely partnerships and collaboration, product design characteristics, service concepts, IT solutions, supply chain processes and organizational characteristics. We present a conceptual framework on a strategic level. In this way companies can create competitive advantages by closing the loop. The results of the literature analysis suggest avenues for future research on the operational and strategic level.     

Is open innovation always the best for SMEs? An exploratory analysis at the project level

Open innovation (OI) projects are increasingly adopted by small‐ and medium‐sized enterprises (SMEs). Yet, undertaking OI is not only a source of opportunities for SMEs as it can, at the same time, present risks. How SMEs manage the balance between the potential benefits and the emerging challenges of OI is still an overlooked topic in the literature. Using evidence gathered through multiple case studies and drawing upon the relational view of the firm, we explore how and why value creation opportunities and different managerial challenges emerge for SMEs pursuing OI projects. We analyze different stages of OI projects in several different contexts of their implementation. Our analysis sheds light on the different nature and dynamics of knowledge involved within OI projects as important boundary conditions affecting successful search paths, learning processes, and the development of appropriability mechanisms. By offering a contextualized view of OI in SMEs, this study also provides insights to business managers on the situational opportunities and constraints of OI, including managerial suggestions on actions to manage tensions within differing OI projects.     

A novel inverse data driven modelling approach to performance-based building design during early stages

Energy analysis at the early stage of building design is a critical, yet difficult task in performance-based design. The difficulty arises from the complex, iterative, and uncertain nature of building design and the challenges of integration with well-posed energy assessment tools. The purpose of this article is to first review characteristics of performance-based design and establish requirements for a methodology that includes generating promising design alternatives, assessing the energy performance in tandem with the generation of alternatives, and choosing an alternative design solution with confidence. The study then proposes a novel systematic data-driven method, based on linear inverse modeling that generates plausible ranges for design parameters given a preferred energy target. The energy performance in this method is described as a linear function of the design parameters for a particular scenario of design. The application of the proposed method in a case study shows that it is capable of helping designers make informed decisions regarding energy performance iteratively and confidently at the early stages of building design.     

Showcase and window to the world: East German architecture abroad 1949–1990

For decades, German Democratic Republic (GDR) architecture was seen as parochial and dictated by the Soviets, yet increasing scholarly interest has generated a picture of debates and specific practices that were embedded in the global process of expansion and crisis of Modernism. Meanwhile, and influenced by the East-West conflict, competing concepts of modernization and national identity arose in the so-called Third World, initiating multifarious cultural transfer processes. This article analyses to what extent the architects from the GDR – a country whose building practice was increasingly shaped by the principles of industrial prefabrication – have played a part in regional contexts and construction methods. It also asks what their role was in international organizations such as Union Internationale des Architects and UNESCO, which promoted their practical engagement abroad. The subject raises issues of possible freedom of action in creative design and fusion processes, but also of bureaucratic constrictions and international relationships ending in unexpected conflicts. The examples outline the field of activities that stretches from pure blueprint delivery for a memorial competition to long-standing work on location when planning whole neighbourhoods. Furthermore, the article examines how the challenges of international planning impacted building culture within the GDR itself.

中国建筑话语中的“文脉”(1980年代-1990年代)

对"文脉"一词进入中国建筑话语的历史作出概览式的回顾,并分别以"阙里宾舍"和"西单商业大楼"为例,从设计者的自述与建筑界的评论入手,探讨1980年代末到1990年代初"文脉热"兴起的可能原因。指出对"复古主义"的批判和创作有"民族特色"建筑的愿望是"文脉"一词背后潜在的诉求,同时,也警醒地看到,基于特定时代背景,中国建筑界对西方后现代主义等建筑思潮不可避免地片面理解和吸收,也造成了"文脉"逐渐丧失了其本应具有的批判性与创造力。     

Value drivers of blockchain technology: A case study of blockchain-enabled online community

There is growing recognition that blockchain technology has significant potential to alter how organizations and people work and communicate. However, theoretical guidance concerning how organizations leverage blockchain technology to enhance value creation for users is still limited. Grounded in the socio-technical perspective and leveraging the rich data obtained from case analyses of blockchain-enabled online communities, this paper develops a theoretical model to identify the core value drivers that blockchain enables for online communities. The core value drivers include: a reputation-value system, data ownership mechanisms, and verification & tracking mechanisms. Our findings suggest that these three value drivers enhance value creation of online communities by motivating participation and protecting contributions.
