    Driven under the Influence: Selected Essays in Theology, 1974-2004

    Get PDF
    The Dutch-born Father Frans Jozef van Beeck has been a Jesuit for nearly 60 years. A respected theologian and teacher, he has written several books on ecclesiology and on the Catholic Church’s relationship with Judaism. Father van Beeck’s multi-volume project, God Encountered: A Contemporary Catholic Systematic Theology, is still a work in progress. Driven Under the Influence is a provocative sampling of his unpublished ideas over a 30-year period. The essays chosen here suggest the breadth and depth of his scholarly interests. They range from fundamental issues such as Christology and Trinitarian theology to encounters with non-Christians, especially Jews, to thorny contemporary issues such as the ordination of women, to very personal reflections on literature and faith. It is a collection sure to stimulate and inspire.https://digitalcommons.sacredheart.edu/shupress_bks/1010/thumbnail.jp

    A New Decision Support Method for Local Energy Planning in Developing Countries.

    Abstract: Energy is required for almost any economic activity. Therefore, regions in developing countries that show rapid economic growth experience a substantial increase in energy demand, creating the need for new energy infrastructure. Energy planning is used to match future energy supply with demand. However, the current (centralized) approach to energy planning is not fit for rapidly developing regions; there is a lack of proper instruments to support the local planning process. This thesis describes the development and first application of a new method that supports energy planners in selecting local energy infrastructure for rapidly developing regions in developing countries. Ultimately, it helps the energy planners to steer the development of the local energy infrastructure into a desirable direction. The method has a multidisciplinary eclectic approach that is referred to as the triple-i approach: it is informative, interactive, and iterative. Field studies in Noord Brabant (the Netherlands) and Huetar Norte (Costa Rica) are used to further develop the method and test its underlying assumptions.

    The role of the STEM Video Game Challenge in the pipeline to tertiary STEM education

    Get PDF
    Rapid recent advances in the technology underpinning STEM careers in addition to growth in key STEM sectors, such as the gaming industry, necessitates some, if not commensurate, change in the STEM education pipeline. The STEM Video Game Challenge (STEM VGC) is a free, annual video game design challenge that aims to scaffold and enrich students and teachers via an authentic and engaging application of STEM principles and practices. As tools to increase teacher and student self-efficacy with technology and improve students’ self-concept in STEM disciplines, initiatives such as STEM VGC are positioned to help increase the flow in the talent pipeline into tertiary STEM education and careers. This presentation: describes the redevelopment and evaluation of the STEM VGC rubric with respect to the position of the challenge and evolving industry requirements, and; identifies key narrowing and leakage points in the pipeline to tertiary STEM education that can be targeted by STEM VGC initiatives

    Introduction of a pseudo-6th order ISDN splitter with bandstop topology

    A newly developed ‘integrated services digital network’ (ISDN) splitter with bandstop (BS) topology is presented and compared to an actual ISDN splitter with a traditional lowpass (LP) topology. The LP-to-BS topology change reduced the amount of filter stages: a LP ISDN splitter requires an 8th order elliptic-like filter in order to be compliant to the standard ‘TS 101 952-1-4 V1.1.1’ [1] of the European Telecommunications Standards Institute (ETSI), whereas the BS ISDN splitter only needs a pseudo-6th order elliptic-like filter. The design of the new BS ISDN filter is discussed in the light of the enforced ETSI specifications. Furthermore, both the ISDN splitters are compared in the field of their specific stopband performance and their physical implementation. The area reduction that comes together with the introduction of the new ISDN splitter with BS topology is more than 25%
