  1. 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)

  2. 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...

  3. An enhanced theory of learning including learning from the future

    Kaiser, Alexander
    Previous studies showed that combining learning based on experiences in the past with learning from an envisioned future scenario results in more innovative and radical ideas as well as in a higher number of covered content domains. However, currently there is no holistic learning theory which integrates both sources of learning. The main purpose of our paper is to propose an enhanced theory of learning, linking the two most important sources of learning: learning from past experiences and learning from the future. Our suggested theory, which is based on the learning theory by Gregory Bateson, will be described in detail....

  6. A Critical Discourse Analysis: The Representation of Hillary Rodham Clinton and Women in the New York Times

    Kopf, Susanne
    This Critical Discourse Analysis investigates the representation of Hillary Rodham Clinton and women in the New York Times during the presidential candidacy campaigns 2008. First, relevant aspects of social practice in the United States of America are introduced. The concept of "women" in U.S. society, prevalent gender stereotypes, the public's perception of Rodham Clinton and leadership ideals are among the facets of social practice that are dealt with in the course of this essay. This is followed by a discussion of how aspects of social practice are drawn upon and utilised in the representation of Rodham Clinton and women by...

  7. A Review of Minority Stress Related to Employees' Demographics and the Development of an Intersectional Framework for Their Coping Strategies in the Workplace

    Köllen, Thomas
    Every employee embodies manifestations of every demographic that attach to him or her different minority and majority statuses at the same time. As these statuses are often related to organizational hierarchies, employees frequently hold positions of dominance and subordination at the same time. Thus, a given individual's coping strategies (or coping behavior) in terms of minority stress due to organizational processes of hierarchization, marginalization and discrimination, are very often a simultaneous coping in terms of more than one demographic. Research on minority stress mostly focuses on single demographics representing only single facets of workforce diversity. By integrating the demographics of age, disability status, nationality, ethnicity, race, sexual orientation,...

  8. Computing Semantic Association: Comparing Spreading Activation and Spectral Association for Ontology Learning

    Wohlgenannt, Gerhard; Belk, Stefan; Schett, Matthias
    Spreading activation is a common method for searching semantic or neural networks, it iteratively propagates activation for one or more sources through a network { a process that is computationally intensive. Spectral association is a recent technique to approximate spreading activation in one go, and therefore provides very fast computation of activation levels. In this paper we evaluate the characteristics of spectral association as replacement for classic spreading activation in the domain of ontology learning. The evaluation focuses on run-time performance measures of our implementation of both methods for various network sizes. Furthermore, we investigate differences in output, i.e. the resulting ontologies, between spreading activation and spectral association. The experiments confirm...

  9. A Prototype for Automating Ontology Learning and Ontology Evolution

    Wohlgenannt, Gerhard; Belk, Stefan; Schett, Matthias
    Ontology learning supports ontology engineers in the complex task of creating an ontology. Updating ontologies at regular intervals greatly increases the need for expensive expert contribution. This naturally leads to endeavors to automate the process wherever applicable. This paper presents a model for automated ontology learning and a prototype which demonstrates the feasibility of the proposed approach in learning lightweight domain ontologies. The system learns ontologies from heterogeneous sources periodically and delegates all evaluation processes, eg. the verification of new concept candidates, to a crowdsourcing framework which currently relies on Games with a Purpose. Furthermore, we sketch ontology evolution experiments to trace trends and patterns facilitated by...

  10. A UML Extension for the Model-driven Specification of Audit Rules

    Hoisl, Bernhard; Strembeck, Mark
    In recent years, a number of laws and regulations (such as the Basel II accord or SOX) demand that organizations record certain activities or decisions to fulfill legally enforced reporting duties. Most of these regulations have a direct impact on the information systems that support an organization's business processes. Therefore, the definition of audit requirements at the modeling-level is an important prerequisite for the thorough implementation and enforcement of corresponding policies in a software system. In this paper, we present a UML extension for the specification of audit properties. The extension is generic and can be applied to a wide variety of UML elements. In a model-driven development (MDD) approach,...

  11. Dimensions and Operationalisations of IT Governance: A Literature Review and Meta-Case Study

    Novotny, Alexander; Bernroider, Edward; Koch, Stefan
    This paper seeks to tackle the current confusion about the constituent dimensions of IT Governance (ITG) and inconsistent operationalisation approaches inhibiting advances in research and organisational ITG practice. Through a structured literature review of ranked high-quality publications augmented by a meta-case study with five underlying projects, we find nine distinct dimensions of ITG. The input-oriented dimensions Compliance Management, IT Investment Management and ITG Improvement have received little attention in earlier conceptualisations, while the more output-oriented dimensions Business/IT Alignment and Business Value Delivery have featured more often in related studies. Scope and application of ITG may depend on the organisational context...

  12. The economic and environmental performance of distribution networks: A case study from the petrochemical industry

    Treitl, Stefan; Jammernegg, Werner
    Designing a company's distribution network is a challenging task that requires the consideration of different aspects. In this respect, especially trade-offs between, for example, operational costs and customer service are the focus of the companies' attention. However, growing concerns of governments and customers about environmental protection have raised awareness towards the environmental impact of operations. Activities associated with the distribution of products, i.e. transportation and warehousing, are not yet subject to strict environmental regulations, but this situation is expected to change soon. Companies must, therefore, start to concentrate not only on economic but also on environmental aspects in the design of their...

  13. Co-Evolution of Information Revolution and Spread of Democracy. 33. Jahrestagung der Gesellschaft für Informatik an der Johann Wolfgang Goethe-Universität in Frankfurt am Main 29.9. - 2.10. 2003

    Frisch, Walter
    This is a short summary of a recent survey [FR03] focusing on the observed evidence, that Internet connectivity is positively correlated with spread of democracy at high levels of significance. The results of multivariate correlation analysis and probabilities regression estimate models are based on the combined analysis of mid - 1991's, to 2001 data series of the Eurostat's and US Census Bureau, the World Bank, and OECD's statistical data service which track the growth of information technology and rating of freedom and democracy worldwide.(author's abstract)

  14. The economic and environmental analysis of a petrochemical distribution network

    Treitl, Stefan; Jammernegg, Werner
    The structure of a company's distribution network is of vital importance for competitiveness but also involves considerable costs. In recent years, competitive pressure as well as regulatory measures, especially in the European Union, have also raised awareness towards the environmental impact of supply chain activities. However, activities associated with the distribution of products are not yet subject to environmental regulations but this might change in the near future. Therefore, companies will have to consider not only economic but also environmental aspects in the design of their supply chains. Based on a case study from the petrochemical industry we present a way to...
