Companies have to assess the benefit of supplier innovation before realization. The specific situation of supplier innovation differs from conventional innovation evaluation because a supplier innovation refers to a subproduct for which the supplier is responsible. To date, supplier innovation evaluation has not been comprehensively discussed in the literature. Therefore, the purpose of this paper is to focus on how supplier innovation should be evaluated.

For this purpose, a case study based on expert interviews has been conducted to identify how supplier innovation is evaluated in practice. On the basis of the empirical findings the specific situation of supplier innovation is discussed in relation to theoretical basics about the object, objective, time, reference, person, recipient, criteria, and methods of evaluation as well as the evaluation and selection process.

Results are recommendations for the special situation of supplier innovation evaluation before their realization in the purchasing company.

Based on the recommendations, a systematic and comprehensive approach with evaluation criteria and methods should be developed. Future research should address useful evaluation criteria and methods.

Managers can use the recommendations to evaluate supplier innovation in practice and to establish a systematic evaluation and selection process for supplier innovation.

The research findings contribute to the literature about innovation management and supplier management research by providing insights into the special situation of supplier innovation evaluation; in particular, this is the first paper which provides a systematic and comprehensive discussion about supplier innovation evaluation.

Blues music is in the midst of its second revival in popularity in roughly thirty years. The year 1960 can be identified, with some qualification, as a reference point for the first rise in international awareness and appreciation of the blues. This first period of wide‐spread white interest in the blues continued until the early seventies, while the current revival began in the middle 1980s. During both periods a sizeable literature on the blues has appeared. This article provides a thumbnail sketch of the popularity of the blues, followed by a description of scholarly and critical literature devoted to the music. Documentary and instructional materials in audio and video formats are also discussed. Recommendations are made for library collections and a list of selected sources is included at the end of the article.

The non-material benefits which people derive from ecosystems, cultural ecosystem services (CES), can be difficult to measure and quantify. This study aims to demonstrate the usefulness of social media analysis.

The widespread use of social media applications has provided a novel methodology for obtaining crowd-sourced data, which can reveal patterns in how social media users interact with urban greenspace and participate in place-making activities. This study explores how urban trees are represented in images tagged with the city of Bolzano, Italy, and uploaded over the course of a year to the image-sharing application Instagram.

A third of all the images contained some elements of green nature, with 3.1% of the images portraying urban trees as the main subject and 11% with urban trees as background features. Seasonal preferences for winter and summer scenes emerged. Accompanying text, in the form of hashtags and image descriptions, was mostly positive and showed how enthusiastically people describe urban nature. An assessment of the images in terms of CES revealed that beyond aesthetic factors and the inspiration to take photographs of nature, a wide range of CES are represented, reflecting the recognition of the benefits of urban trees by Instagrammers. The collection of images provided a unique snapshot of the city of Bolzano.

This reinforces the importance of urban trees within planning policy for providing sense of place, recreation and stress relief for residents and tourists.

The study builds on recent advances in social media research, focussing on the important field of urban CES.

This study aims to investigate the role of professors as gatekeepers for sustainable development competencies (SDC) in disciplinary study programs. It aims to understand which factors are crucial for professors to integrate SDC into their teaching, their basic understanding of SDC, the actual degree of SDC integration and how suitable they perceive student-centered teaching strategies for teaching SDC.

The results are based on the qualitative content analysis of interviews with 16 professors after they participated in a didactic training program focused on combining student-centered teaching strategies with SDC.

Psychological factors, like the attribution of responsibility, value orientations and cost-benefit considerations, are not the only reasons for integrating SDC into a course, as disciplinary requirements play their role. When teaching SDC, professors focus on systems-thinking, strategic and normative competencies. They consider student-centered teaching strategies especially suitable to teach systems-thinking and interpersonal competencies.

Promoting changes toward teaching SDC may best be done by supporting professors’ intrinsic motivations: by fulfilling the need for growth in teaching skills, activating values and creating an environment in which everybody feels responsible for teaching SDC.

Teaching SDC with student-centered teaching strategies is relevant even in study programs that show little relation to sustainability issues. professors are experts in their field, but not necessarily in the field of sustainability. Understanding how such professors might include sustainable development competency development in their syllabi can widen the influence of SDC on higher education.

Mega sport events (MSE) are immensely popular but also highly criticized because these include large public budgets and involve politically sensitive topics. In this context, there is an increasing attention toward legacy planning, the effort to confer long‐term benefits to a host destination through organizing MSEs, such as the Olympic Games. When it comes to event planning, large‐scale master plans are a common approach. However, in the Netherlands the authors see that an alternative development model is pursued called the Dutch Approach to prepare for the possible candidature to host the Olympic Games of 2028. This paper aims to analyze this approach with a specific focus on whether this approach has the potential to result in a positive legacy.

The research involves a literature review which distinguishes factors that positively or negatively influence event legacies. This results in a framework which is used as a guide for a content analysis of data on the Dutch Approach. Hence, data are obtained from analyzing academic and professional literature, policy documents, research reports, and newspaper articles on the Dutch Olympic ambitions, and the planning approach thereof. Moreover, data are derived from a study by the authors on the development of the area “Sportas Amsterdam”.

The research identifies factors that can contribute positively and negatively to the legacy of events. It provides a unique insight into the planning process of The Netherlands in the context preparing a bid for the Olympic Games of 2028. What can be learned from the Dutch Approach is that planning for a positive legacy is a long‐term and complex process that heavily relies on the support of a range of stakeholders. Due to the range of actors involved, it involves much negotiations and becomes increasingly difficult to achieve consensus.

The paper provides a reflection on the concepts of legacy and legacy planning, and outlines a set of propositions concerning the future of MSEs that present an agenda for further research. By doing to, the paper highlights the importance of focusing on how the relations between stakeholder involvement, planning approaches, and types of urban regimes influence the extent to which a positive legacy can be achieved.

The paper provides a state of the art overview of contributions on event legacy and legacy planning. It draws attention to conditions for positive legacies and implications for planning and governance approaches. It is argued that a top‐down government‐led approach to a MSE will probably have less impact on future tourism compares to the Dutch Approach.

Artificial intelligence (AI) is currently one of the most disruptive technologies and can be applied in many different use cases. However, applying AI in regulated environments is challenging, as it is currently not clear how to achieve and assess the fairness, accountability and transparency (FAT) of AI. Documentation is one promising governance mechanism to ensure that AI is FAT when it is applied in practice. However, due to the nature of AI, documentation standards from software engineering are not suitable to collect the required evidence. Even though FAT AI is called for by lawmakers, academics and practitioners, suitable guidelines on how to document AI are not available. This interview study aims to investigate the requirements for AI documentations.

A total of 16 interviews were conducted with senior employees from companies in the banking and IT industry as well as with consultants. The interviews were then analyzed using an informed-inductive coding approach.

The authors found five requirements for AI documentation, taking the specific nature of AI into account. The interviews show that documenting AI is not a purely technical task, but also requires engineers to present information on how the AI is understandably integrated into the business process.

This paper benefits from the unique insights of senior employees into the documentation of AI.

When established markets in the West are stagnating or in crisis, companies increasingly look to emerging markets, especially the so-called BRICs, for growth potential. However, these new markets also pose unique challenges, for which the best practices and assumptions of Western managers are not automatically suited. Setting up supply chains in new regions confronts firms with multiple challenges in terms of regulation, resources, culture, and infrastructure. In this case study, students will accompany a successful German FMCG manager as he plans his company’s expansion into Russia, and is forced to look at the opportunities and challenges from a new perspective.

The purpose of this paper is to deliver an insight into the interaction effects of process‐oriented management and business intelligence (BI).

The paper takes up publications from the fields of BI and business process management and analyzes the state‐of‐the‐art of process‐centric business intelligence (PCBI). To highlight the potentials and limitations of the concept, two exemplary use cases are presented and discussed in depth. Furthermore, a vision for the technical implementation is sketched.

PCBI is found to play an important role in an organization's strive for competitiveness. The concept's potential benefits are significant. However, the overall levels of adoption and maturity of the concept within real‐world organizations appear to be rather low at the moment.

The paper discusses solely two exemplary use cases – the most that could be done within the scope of a journal publication. Therefore, the explanatory power and the representativeness of the results need to be scrutinized in detail.

The paper highlights the practical significance of PCBI. It therefore represents a useful source of information for both practitioners and academics who are interested in improving the efficiency and effectiveness of an organization's information supply in support of its processes.

The paper motivates, describes, and analyzes the concept of PCBI. Furthermore, it provides examples of the concept's adoption and benefits from a practitioner's point of view.

The purpose of this study is to develop laboratory techniques to evaluate the inhibition efficiency of salt neutralizer (SN) solutions in the corrosion protection of metal alloys associated with winter maintenance equipment.

The corrosion resistance of alloys A36, B36 and B152 treated with SNs was evaluated by accelerated corrosion testing (ASTM B117) and electrochemical polarization curves. Characterization of inhibition solutions was performed by contact angle measurements, scanning electron microscopy, ultraviolet-visible spectroscopy and Fourier transform infrared spectroscopy.

Salt neutralizer systems act as mixed inhibitors in acidic media by changing the corrosion resistance ability of metal alloys because of the adsorption of surfactant molecules through their hydrophilic heads. The correlation of the corrosion rate of metal alloys and the inhibitor efficiency showed the influence of the SN type, its concentration, its effective adsorption constant and its contact angle on the alloy surface. Salt neutralizers with higher manufacturer’s recommended wash concentrations (MRWC) to critical wash concentration ratio, lower contact angle on the alloy surface and higher K_eff were more successful at preventing corrosion on the alloys tested.

The results of this work provide, for the first time, both quantitative and qualitative information of the properties of washing techniques in the use of effective cleaning strategies for protecting winter maintenance equipment from corrosion. Other state departments of transportation facing similar weather conditions will be benefited by identifying measures and techniques to increase the corrosion resistance of their equipment assets.
