  1. Strategies for executing federated queries in SPARQL1.1

    Buil-Aranda, Carlos; Polleres, Axel; Umbrich, Jürgen
    A common way for exposing RDF data on the Web is by means of SPARQL endpoints which allow end users and applications to query just the RDF data they want. However, servers hosting SPARQL endpoints often restrict access to the data by limiting the amount of results returned per query or the amount of queries per time that a client may issue. As this may affect query completeness when using SPARQL1.1's federated query extension, we analysed different strategies to implement federated queries with the goal to circumvent endpoint limits. We show that some seemingly intuitive methods for decomposing federated queries provide unsound results in the general case, and...

  2. Data Integration for Open Data on the Web

    Neumaier, Sebastian; Polleres, Axel; Steyskal, Simon; Umbrich, Jürgen
    In this lecture we will discuss and introduce challenges of integrating openly available Web data and how to solve them. Firstly, while we will address this topic from the viewpoint of Semantic Web research, not all data is readily available as RDF or Linked Data, so we will give an introduction to different data formats prevalent on the Web, namely, standard formats for publishing and exchanging tabular, tree-shaped, and graph data. Secondly, not all Open Data is really completely open, so we will discuss and address issues around licences, terms of usage associated with Open Data, as well as documentation of data provenance. Thirdly, we will discuss issues connected...

  3. Management und Quantenphysik. Das Beispiel TELE

    Camen, Jutta; Müller-Camen, Michael; Stelzmann, Markus
    Die Managementpraxis ist immer noch stark vom Weltbild der klassischen Physik und damit von Reduktionismus, Determinismus und Positivismus geprägt. Ziel dieses Beitrages ist am Beispiel der Wiener Firma TELE zu illustrieren, wie das Paradigma der Quantenphysik in einer Zeit, die durch schnelle Veränderungen und unvorhersehbare Unternehmensumwelten gekennzeichnet ist, Management inspirieren kann. Nach einer kurzen Einführung in die klassische Physik, werden am Beispiel der quantenphysikalischen Phänomene Welle-Teilchen Dualismus, Heisenbergsche Unschärferelation und Feldtheorie Aspekte eines daran orientierten Quantenmanagement illustriert.

  5. From Social Rights to Economic Incentives? The Moral (Re)construction of Welfare Capitalism

    Frerichs, Sabine
    The notion of 'welfare capitalism' refers to a political-economic regime that integrates the functions of a capitalist market economy with the functions of a democratic welfare state. The term is commonly used by Esping-Andersen (1990) in The Three Worlds of Welfare Capitalism, but it is also linked to Marshall's (1950, p.14) idea of three generations of rights, which all form part of modern citizenship: civil rights, political rights, and social rights. The question that this chapter seeks to address is how social rights, which Esping-Andersen and Marshall understood as the apex of the democratic welfare state, remain bound to the...

  6. The Rule of the Market: Economic Constitutionalism Understood Sociologically

    Frerichs, Sabine
    Setting out from the works of Max Weber and Karl Polanyi, this chapter outlines a sociology of economic constitutionalism. The starting point is a functional definition of economic constitution as the law constituting the market order, no matter if it is public or private, national or international, official or informal law. Economic constitutionalism is understood as a system of thought, which emphasises the role of a liberal economic constitution in integrating the global economy. Adapting Weber's ideal-typical method, the economic constitution is conceived as a constitutional ideal type, next to juridical constitution, political constitution, social constitution, and security constitution. Sociologically...

  7. What Is the 'Social' in Behavioural Economics? The Methodological Underpinnings of Governance by Nudges

    Frerichs, Sabine
    Behavioural economics builds on psychology rather than on sociology, and on cognitive science rather than the science of culture. The same is true for new behavioural scholarship in the legal discipline, whether this is referred to as 'behavioural law and economics' or 'law and the behavioural sciences'. The result of a one-sided definition of a more realist research agenda in legal scholarship is an impoverished understanding of the 'social'. In Thaler and Sunstein's famous concept of nudging, social conformity appears as a property of the individual, which can be instrumentalized by social nudges. More generally, the cognitive strand of behavioural...

  8. Intersexuality and Trans-Identities within the Diversity Management Discourse

    Köllen, Thomas
    Within both the scientific discourse on workforce diversity, and diversity management practice, intersexuality and transgender issues have hitherto remained marginalized topics. This chapter gives an overview of the discourses on both phenomena, and proposes starting points for more inclusive organizational diversity management initiatives. It is shown that both topics represent different aspects of the category of "gender". The common practice of conceptually lumping together intersexuality, transgenderism, and sexual orientation can be seen as one important reason that intersexuality and transgenderism are rarely considered in organizational diversity management programs in terms of concrete action. Against this background, a modified, and more...

  9. Time Series Petri Net Models - Enrichment and Prediction

    Rogge-Solti, Andreas; Vana, Laura; Mendling, Jan
    Operational support as an area of process mining aims to predict the temporal performance of individual cases and the overall business process. Although seasonal effects, delays and performance trends are well-known to exist for business processes, there is up until now no prediction model available that explicitly captures this. In this paper, we introduce time series Petri net models. These models integrate the control flow perspective of Petri nets with time series prediction. Our evaluation on the basis of our prototypical implementation demonstrates the merits of this model in terms of better accuracy in the presence of time series effects.

  10. Towards a Knowledge-Based Theory of Developing Sustainable Visions: The Theory Wave

    Kaiser, Alexander
    Although research and practice agree that visions are essential for organizations, the process of vision development remains elusive in academic literature. Presenting the "theory wave", this paper proposes a knowledge-based theory for developing sustainable visions to guide the creation of measures and actions in the future. Central to the theory wave, we suggest three features that characterize the development of sustainable visions; (1) learning from an envisioned future, (2) need orientation and (3) a wavelike process combining top-down and bottom-up approaches. Furthermore, by enhancing the creation of different kinds of knowledge, the theory-wave entails aspects of research on knowledge creation...

  11. Financial decisions in the household

    Kamleitner, Bernadette; Mengay, Till; Kirchler, Erich
    Financial decisions are a frequent occurrence within households. Depending on characteristics of the relationship between household members, the situation, and the concrete decision object, decisions can either be made jointly by multiple members of the household or individually by one member. This chapter outlines the four types of financial decisions (spending, saving and credit use, investment, money management) and identifies key parameters that are specific to and guide each of these decisions. The parameters that matter for a decision vary depending on whether a decision is being made individually or jointly. To understand the theoretical and practical implications of a decision...

    Process mining techniques are able to extract knowledge from event logs commonly available in today's information systems. These techniques provide new means to discover, monitor, and improve processes in a variety of application domains. There are two main drivers for the growing interest in process mining. On the one hand, more and more events are being recorded, thus, providing detailed information about the history of processes. On the other hand, there is a need to improve and support business processes in competitive and rapidly changing environments. This manifesto is created by the IEEE Task Force on Process Mining and aims...

  18. Investigating the Impact of Need Knowledge on Strategy Development in Organizations

    Kragulj, Florian; Fahrenbach, Florian
    Strategy development results from a knowledge-creating process to guide organizational behavior and achieve (long-term) goals. However, a strategy rarely considers the needs of the organization and its members explicitly. If known and considered, needs might have an existential impact on behavior. Therefore, we propose that a profound strategy should take into account needs. Arguably, the generation of any strategy can be considered as an organizational learning process, which is shaped by and results in knowledge. Therefore, a knowledge perspective might be helpful to study what impact the consideration of needs has on the outcome of a strategy development process. Since...

  19. A Knowledge Perspective on Needs as a Foundation for Organisational Learning Processes

    Kragulj, Florian
    Needs are crucial in organisational learning processes, but yet not formally conceptualised as a distinct type of knowledge. In this conceptual paper, I establish a knowledge perspective on needs and the transformation process from needs towards need satisfaction. Based on an ontology clarifying the concept of need and its means of satisfaction, I introduce need-based solution knowledge consisting of three distinct capacities to act. I argue why these capacities should be made explicit in group settings and point at possible leverage points for organisational practice. (author's abstract)

  20. Imageries of corporate social responsibility: Visual recontextualization and field-level meaning

    Höllerer, Markus; Jancsary, Dennis; Meyer, Renate; Vettori, Oliver
    In this paper, we explore how corporations use visual artifacts to translate and recontextualize a globally theorized managerial concept (CSR) into a local setting (Austria). In our analysis of the field-level visual discourse, we analyze over 1,600 images in stand-alone CSR reports of publicly traded corporations. We borrow from framing analysis and structural linguistics to show how the meaning structure underlying a multifaceted construct like CSR is constituted by no more than a relatively small number of fundamental dimensions and rhetorical standpoints (topoi). We introduce the concept of imageries-of-practice to embrace the critical role that shared visual language plays in...
