Rough set theory is a simple and potential methodology in extracting and minimizing rules from decision tables. Its concepts are core, reduct and discovering knowledge in the form of rules. The decision rules explain the decision state to predict and support the new situation. Initially it was proposed as a useful tool for analysis of decision states. This approach produces a set of decision rules involves two types namely certain and possible rules based on approximation. The prediction may highly be affected if the data size varies in larger numbers. Application of Rough set theory towards this direction has not been considered yet. Hence the main objective of this paper is to study the influence of data size and the number of rules generated by rough set methods. The performance of these methods is presented through the metric like accuracy and quality of classification. The results obtained show the range of performance and first of its kind in current research trend.

This study aims to elucidate the quantitative and qualitative differences in employment development between German districts. Building on ideas from competitive development and resource-based theory, the paper particularly seeks to explain enduring East-West differences between rural regions by two different forms of competitive advantage: cost leadership and quality differentiation.

This study follows a two-step empirical approach: First, an extended shift-share regression is conducted to analyze employment development in Western and Eastern German districts between 2007 and 2016. Second, the competitive share effect and other individual terms of the shift-share model are further examined in additional regressions using regional economic characteristics as exogenous variables.

The findings suggest that the above-average employment growth of the rural districts in the West is owed to the successful exploitation of experience in manufacturing that has been gathered by firms in the past 100 years or so. While their strategy is largely based on advanced and specialized resources and an innovation-driven differentiation strategy, the relatively weak employment development of Eastern rural districts might be explained by a lack of comparable long-term experiences and the related need to focus on the exploitation of basic and general resources and, accordingly, on the efficiency-based strategy of cost leadership.

This study offers an in-depth empirical analysis of how the competitive share effect, i.e. region-specific resources beyond industry structure, contributes to regional employment development. The analysis reveals that quantitative differences in rural employment development are closely related to qualitatively different levels of input factors and different regimes of competitiveness.

Computer corpus linguistics (CCL) is a scientific innovation that has facilitated the creation and analysis of large corpora in a systematic way by means of computer technology since the 1950s. This article provides an account of the CCL pioneers in general but particularly of those in Germany, the Netherlands, Sweden, and Switzerland. It is found that Germany and Sweden, due to more advantageous financing and weaker communities of generativists, had a faster adoption of CCL than the other two countries. A particular late adopter among the four was Switzerland, which did not take up CCL until foreign professors had been recruited.

The purpose of this paper is to provide a technical review of a new Bernoulli gripper development using computed fluid dynamics (CFD) modeling, and also to outline an appropriate independent testing method for validating and evaluating process capability in terms of automated thin wafer handling. The investigation has been carried out by a collaborative way of Festo and Fraunhofer IPA as a connecting link between applied research and industrial needs.

Following an introduction, the paper first describes the basic development and fundamental principles of a gripper based on Bernoulli's law. The gripper was dimensioned and designed with the aid of CFD methods. The performance of the hardware was tested using extreme parameter settings while gripping thin, fragile workpieces. The performance of the gripper was tested from the aspects of shortest cycle times, positioning accuracy and air consumption and followed a manufacturer-independent design of experiments. A characterization of the gripping force generated during horizontal and vertical tension tests provides conclusive closed loop validation with regard to the gripper's air flow in the initial CFD model.

Photovoltaic (PV) grippers are challenging components since the handling objects, 200-120 μm thin crystalline silicon wafers with an area of 156×156 mm, are one of the most fragile parts as far as required handling speeds and cycle times are concerned.

The paper provides a detailed technical review of a CFD application used in the development of a Bernoulli gripper and also describes a method for testing and evaluating PV grippers for industrial scale applications. The article presents the results of a close cooperation regarding an industrial development (Festo AG & Co. KG) and independent applied research (Fraunhofer IPA) for advanced product benchmarking and validation in a relatively young but dynamic and increasingly-automated PV industry.

Looks at the university at the end of the nineteenth century using the concept of a “social institution”, and applying four approaches. A functional analysis provides insights into the kinds of knowledge a university produces. Examination of changes in these functions in the nineteenth century emphasizes the new institutions that were founded and changes in the recruitment of social elites. Political analysis looks at outside influences and considers especially the powers of nation, church and state. A structural analysis discusses organizational and resource issues. Sociocultural analysis reveals the principles of universities: priority of research, combination of research and teaching, freedom of scholarship and the problem of Bildung.

(Digital) servitization, referring to service-driven strategies and their increasing implementation in manufacturing, is one of the most rapidly growing areas in industrial service research. However, the cultural change involved in successful servitization is a phenomenon that is widely observed but poorly understood. This research aims to clarify the processes of social construction as manufacturers change their organizational culture to transform into industrial service providers.

This research takes a systematic approach to integrate disparate literature on servitization into a cohesive framework for cultural change, which is purposefully augmented by rationale culled from organizational learning and sensemaking literature.

The organizational learning framework for cultural change in servitization introduces a dynamic perspective on servitizing organizations by explaining social processes between organizational and member-level cultural properties. It identifies three major cultural orientations toward service, digital and learning that govern successful servitization.

This research contributes to the servitization literature by presenting a new approach to reframe and explore cultural change processes across multiple levels, thus providing a concrete starting point for further research in this area.

This article reports on the background, the conceptual ideas and the lessons learned from over more than 20 years of IC Statements and Management with a country focus on Germany and some international developments. It calls for an integrated management approach for IC and offers case study evidence on how to accomplish this quest.

Report on the German initiative “Intellectual Capital Statement made in Germany” (ICS m.i.G.). A brief review of the literature describes the background and theoretical foundation of the German IC method. A short description of the method is followed by four detailed case studies to illustrate long-term impact of IC management in very different organizations. A discussion of Lessons Learned from more than 200 implementations and an outlook on current and future developments finalizes the article.

IC Statements made in Germany (ICS m.i.G.) was successful in providing a framework to systematically identify IC, evaluate the status quo of IC relative to the strategic requirements, visualize interdependencies of IC, business processes and business results as well as to connect IC reporting with internal management routines and external communication. However, ICS is not an insulated method but delivers the maximum benefit when integrated with strategy development, strategy implementation, business process optimization accompanied by change management routines. Strong ties to human resource management, information technology departments, quality management, research and development teams as well as business operations as the core of an organization help to yield the most for ICS m.i.G. Over time, the focus of managing IC changes and maturity leads to deutero learning.

ICS m.i.G. proved easy to apply, cost efficient for SMEs, larger corporations and networks. It helps to better accomplish their objectives and to adjust their business models. The guidelines in German and English as well as a software application released were downloaded more than 100,000 times. A certification process based on a three-tier training module is available and was successfully completed by more than 400 practitioners. ICS m.i.G. is supporting current standards of knowledge management, such as ISO 9001, ISO 30401 or DIN SPEC PAS 91443 and therefore will most likely have a continuing impact on knowledge-based value creation.

This paper reports lessons learned from the country-wide IC initiative in Germany over the last 20 years initiated and supported by the authors. Several elements of the method have been published over time, but so far no comprehensive view on Lessons Learned had been published.
