Bewertung von cyber-physischen Systemen – State of the ArtPfaff, Constanze 04 May 2023 (has links)
Unternehmen werden gegenwärtig mit den Themen der Nachhaltigkeit und der fortschreitenden Industrie 4.0 vor immer komplexere Herausforderungen gestellt. Ein Bestandteil der neuen Basistechnologien stellen cyber-physische Systeme (CPS) dar, die bereits gegenwärtig und zukünftig mit den Zielen der nachhaltigen Entwicklung in Einklang gebracht werden müssen. Die vorliegende Arbeit geht den Forschungsfragen nach, wie CPS definiert, charakterisiert und unter Einbezug nachhaltiger Kriterien bewertet werden können. Dazu wurden verschiedene, betriebswirtschaftliche Instrumentarien ausgewählt und systematisiert, die folgend im eigens entwickelten und angewandten „Vorgehensmodell zur Prüfung und Eignung
von Bewertungsinstrumenten für CPS unter Einbezug der Nachhaltigkeit“ überprüft wurden.
Die Untersuchung ergab, dass der Bedarf an Bewertungsansätzen von CPS in Kombination mit der Thematik der Nachhaltigkeit besteht und mit existenten, betriebswirtschaftlichen Methoden größtenteils bewältigt werden kann.
Die zugrunde liegende Masterarbeit wurde an der Professur Unternehmensrechnung und Controlling (Technische Universität Chemnitz) durch Prof. Dr. Prof. h. c. Uwe Götze sowie Kristina Höse (M.Sc.) betreut. / Companies are currently facing increasingly complex challenges with the issues of sustainability and the advancing Industry 4.0. One component of the new enabling technologies are cyber-physical systems (CPS), which already currently and in the future need to be aligned with sustainable development goals. This thesis addresses the research questions of how CPS can be defined, characterized and evaluated with respect to sustainable criteria. For this purpose, various business management tools were selected and systematized, which were subsequently reviewed in the specially developed and applied 'Procedure Model for the Examination and Suitability of Assessment Tools for CPS with the Inclusion of Sustainability'. The investigation showed that the need for evaluation approaches of CPS in combination with the topic of sustainability exists and can be handled with existing, business management methods to a large extent.

Researches regarding the evolution, magnitude and complexity of the impact generated by the economic activities on the East Jiu RiverSimion, Alexandru Florin 07 July 2023 (has links)
Ongoing development of modern society, based on consumption of goods and services, leads to the increase of compulsoriness of economic agents to face market requirements by increasing the degree of local and regional industrialization. Establishment of new economic activities generates negative pressures on the environment and surface waters, generating increased pollution, manifested by vulnerability of aquatic ecosystems to stressors.
Preliminary studies carried out within the doctoral thesis entitled 'Research on the evolution, magnitude and complexity of the impact of economic activities on the East Jiu' include information on characteristic elements of the East Jiu River basin, in accordance with the Water Framework Directive 2000/60/CE.
The objectives of the field research aimed to identify economic activities in the eastern Jiu Valley generating an impact on the environment (especially the mining industry, but also timber exploitation and processing, local agriculture, animal husbandry and waste storage), establishing a quarterly monitoring program of the river basin, identification of flora and fauna species and identification of areas vulnerable to potential pollution.
Based on observations made in situ and on information obtained from the evolution process of the monitoring program, the appropriate methodologies for assessing physical-chemical and ecological quality of the water were selected.
Study of the evolution of the impact generated by economic activities on the East Jiu was carried out by mathematical modelling, with finite volumes, of the East Jiu River basin and plotting of pollutant dispersion maps. The magnitude and complexity of impact generated by economic activities was studied by using a complex system based on fuzzy logic, designed based on interactions between natural and artificial systems, between physical-chemical indicators of water and ecosystem. The research carried out substantiates in development of necessary technical measures to reduce the impact generated by economic activities located in eastern Jiu Valley, without significantly changing the hydrodynamics of the river basin.
Following research, during different research stages, methods, techniques and tools were designed and accomplished with the help of which, water and aquatic ecosystems’ quality can be assessed, as well as the impact generated by human activity on the Jiu River, at a given moment and/or continuously.:CONTENT

Ökologie, Ökonomie und Soziales im Biologieunterricht / Konzepte von LehrkräftenHellwig, Hauke 14 October 2009 (has links)
Der Umweltunterricht in Biologie befindet sich in der Orientierung zwischen Zwängen zur Reduktion auf naturwissenschaftliches Basiswissen (scientific literacy), den Kompetenzansprüchen der traditionellen Umweltbildung (environmental literacy) und der zuletzt implementierten Bildung für Nachhaltigkeit (BNE) mit dem Ziel Gestaltungskompetenz (sustainability literacy). Die hier präsentierte Studie diente neben der Bestimmung und Diskussion des Ist-Standes bei der Vermittlung umweltbezogener Gesichtspunkte im Rahmen des Faches Biologie auch der Entwicklung eines entsprechenden Instrumentes zur Erfassung der Unterrichtskonzepte von Lehrpersonen. Die Identifikation der Unterrichtskonzepte ging von Lehrkräften und deren Befragung in einem Ländervergleich zwischen Deutschland und Schweden aus. Methodisch wurde eine Kombination aus qualitativen und quantitativen Verfahren umgesetzt. Drei latente Erklärungsvariablen für die Antwortmuster der Lehrpersonen wurden faktorenanalytisch identifiziert und in verschiedenen Erhebungswellen validiert. Darauf basierend wurden drei kurze Testskalen gebildet. Ein zweites Auswertungsverfahren bestand in der Clusteranalyse der befragten Lehrkräfte. Indem die Cluster mit den Skalen in Beziehung gesetzt wurden, konnten anhand der Varianz der Gruppenmittelwerte verschiedene Profile identifiziert werden. Dies führte zur Beschreibung von je sechs qualitativ und quantitativ differenzierbaren Unterrichtskonzepten in Deutschland und Schweden als reservierte, minimalistische, traditionelle, neuorientierte, ambivalente und pluralistische Realisierung von Umweltbiologie. Während der reservierte Ansatz in Schweden nicht auftritt, kann dort „theoretische Umweltbiologie“ unterschieden werden. Beim derzeitigen Aus- und Fortbildungsstand der Lehrkräfte ist die Umsetzung von BNE in Deutschland nicht adäquat gewährleistet. Gründe dafür liegen im disziplinären Vermittlungsmodus, mit dem die Entwicklung überfachlicher Kompetenzen kaum vereinbar ist. / Environmental education has been implemented interdisciplinary at school in Germany. On the contrary, teacher training still remains emphasizing specific scientific subjects. Only recently, different initiatives towards education for sustainable development (ESD) are under way on state level, sub-state level and local level. However, common criteria for designing interdisciplinary teaching processes have not become obvious in Germany. There is a risk, therefore, that teachers will make decisions concerning aims, content and methods based solely on intuition. The study presented here identifies and discusses the existing state of concepts of environmental biology among biology teachers with respect to scientific literacy, environmental literacy and sustainability literacy. A wide range of different aspects of didactics in environmental biology was identified and gathered from biology teachers and scientists in Germany and Sweden. Following classical test theory, the diverse statements were eventually transformed into a closed Likert-scale questionnaire. In two preliminary studies and in the main study that was conducted across the whole of Germany, three dimensions were identified and validated by means of factor analysis. Using cluster analysis, six concepts can be distinguished: pluralistic, ambivalent, realigned, traditional, minimalist and reserved realisation of environmental biology. Biology teachers generally refer to a disciplinary science orientated teaching repertoire when addressing environmental education, which is not adequate to ESD theory. Following the investigation in Sweden, also six concepts can be distinguished. Instead of the reserved concept, a theoretic realisation exists in Sweden suitable for facilitation of sustainability literacy. In five types of realising environmental biology, a high degree of agreement was identified between perceptions of teachers in Germany and Sweden.

The 20th Anniversary of the 2005 UNESCO Convention on the Protection and Promotion of Cultural Expressions: Are the Convention’s Objectives (still) “Fit for Future”?von Schorlemer, Sabine, Merkel, Christine M. 17 January 2025 (has links)
For two decades, the 2005 UNESCO Convention on the Protection and Promotion of the Diversity of Cultural Expressions (DCE) has played a pivotal role in shaping international cultural policy. This article explores the actual relevance of the Convention's Objectives against the backdrop of current global challenges such as poverty, climate change, digitization, and gender equality. The authors reflect on the Convention’s effectiveness in fostering international cooperation, supporting cultural policies, and promoting the inclusion of culture in development agendas. Notwithstanding emerging obstacles, the Convention’s framework has consistently been reaffirmed and shown dynamic adaptability to new developments, particularly through its doctrinal intersections with human rights law and its influence on States’ cultural policies. Key institutional mechanisms such as the International Fund for Cultural Diversity and initiatives like the 'Fair Culture' movement underscore the Convention’s role in promoting sustainable cultural development and equitable trade in cultural goods and services. In conclusion, with its broad framework of Objectives, the 2005 Convention remains a vital instrument in fostering cultural diversity, capable of responding to evolving global priorities while advocating for solidarity and creative collaboration among member States and civil society.:Introduction 1

Challenges and potentials of channeling local philanthropy towards development and aocial justice and the role of waqf (Islamic and Arab-civic endowments) in building community foundations / the case of EgyptDaly, Marwa El 16 May 2012 (has links)
Diese Arbeit bietet eine solide theoretische Grundlage zu Philanthropie und religiös motivierten Spendenaktivitäten und deren Einfluss auf Wohltätigkeitstrends, Entwicklungszusammenarbeit und einer auf dem Gedanken der sozialen Gerechtigkeit beruhenden Philanthropie. Untersucht werden dafür die Strukturen religiös motivierte Spenden, für die in der islamischen Tradition die Begriffe „zakat“, „Waqf“ oder im Plural auch „awqaf-“ oder „Sadaqa“ verwendet werden, der christliche Begriff dafür lautet „tithes“ oder „ushour“. Aufbauend auf diesem theoretischen Rahmenwerk analysiert die qualitative und quantitative Feldstudie auf nationaler Ebene, wie die ägyptische Öffentlichkeit Philanthropie, soziale Gerechtigkeit, Menschenrechte, Spenden, Freiwilligenarbeit und andere Konzepte des zivilgesellschaftlichen Engagements wahrnimmt. Um eine umfassende und repräsentative Datengrundlage zu erhalten, wurden 2000 Haushalte, 200 zivilgesellschaftliche Organisationen erfasst, sowie Spender, Empfänger, religiöse Wohltäter und andere Akteure interviewt. Die so gewonnen Erkenntnisse lassen aussagekräftige Aufschlüsse über philanthropische Trends zu. Erstmals wird so auch eine finanzielle Einschätzung und Bewertung der Aktivitäten im lokalen Wohltätigkeitsbereich möglich, die sich auf mehr als eine Billion US-Dollar beziffern lassen. Die Erhebung weist nach, dass gemessen an den Pro-Kopf-Aufwendungen die privaten Spendenaktivitäten weitaus wichtiger sind als auswärtige wirtschaftliche Hilfe für Ägypten. Das wiederum lässt Rückschlüsse zu, welche Bedeutung lokale Wohltätigkeit erlangen kann, wenn sie richtig gesteuert wird und nicht wie bislang oft im Teufelskreis von ad-hoc-Spenden oder Hilfen von Privatperson an Privatperson gefangen ist. Die Studie stellt außerdem eine Verbindung her zwischen lokalen Wohltätigkeits-Mechanismen, die meist auf religiösen und kulturellen Werten beruhen, und modernen Strukturen, wie etwa Gemeinde-Stiftungen oder Gemeinde-„waqf“, innerhalb derer die Spenden eine nachhaltige Veränderung bewirken können. Daher bietet diese Arbeit also eine umfassende wissenschaftliche Grundlage, die nicht nur ein besseres Verständnis, sondern auch den nachhaltiger Aus- und Aufbau lokaler Wohltätigkeitsstrukturen in Ägypten ermöglicht. Zentral ist dabei vor allem die Rolle lokaler, individueller Spenden, die beispielsweise für Stiftungen auf der Gemeindeebene eingesetzt, wesentlich zu einer nachhaltigen Entwicklung beitragen könnten – und das nicht nur in Ägypten, sondern in der gesamten arabischen Region. Als konkretes Ergebnis dieser Arbeit, wurde ein innovatives Modell entwickelt, dass neben den wissenschaftlichen Daten das Konzept der „waqf“ berücksichtigt. Der Wissenschaftlerin und einem engagierten Vorstand ist es auf dieser Grundlage gelungen, die Waqfeyat al Maadi Community Foundation (WMCF) zu gründen, die nicht nur ein Modell für eine Bürgerstiftung ist, sondern auch das tradierte Konzept der „waqf“ als praktikable und verbürgte Wohlstätigkeitsstruktur sinnvoll weiterentwickelt. / This work provides a solid theoretical base on philanthropy, religious giving (Islamic zakat, ‘ushour, Waqf -plural: awqaf-, Sadaqa and Christian tithes or ‘ushour), and their implications on giving trends, development work, social justice philanthropy. The field study (quantitative and qualitative) that supports the theoretical framework reflects at a national level the Egyptian public’s perceptions on philanthropy, social justice, human rights, giving and volunteering and other concepts that determine the peoples’ civic engagement. The statistics cover 2000 households, 200 Civil Society Organizations distributed all over Egypt and interviews donors, recipients, religious people and other stakeholders. The numbers reflect philanthropic trends and for the first time provide a monetary estimate of local philanthropy of over USD 1 Billion annually. The survey proves that the per capita share of philanthropy outweighs the per capita share of foreign economic assistance to Egypt, which implies the significance of local giving if properly channeled, and not as it is actually consumed in the vicious circle of ad-hoc, person to person charity. In addition, the study relates local giving mechanisms derived from religion and culture to modern actual structures, like community foundations or community waqf that could bring about sustainable change in the communities. In sum, the work provides a comprehensive scientific base to help understand- and build on local philanthropy in Egypt. It explores the role that local individual giving could play in achieving sustainable development and building a new wave of community foundations not only in Egypt but in the Arab region at large. As a tangible result of this thesis, an innovative model that revives the concept of waqf and builds on the study’s results was created by the researcher and a dedicated board of trustees who succeeded in establishing Waqfeyat al Maadi Community Foundation (WMCF) that not only introduces the community foundation model to Egypt, but revives and modernizes the waqf as a practical authentic philanthropic structure.
