Introduction of renewable energy sources in the district heating system of Greece

Nikolaos Margaritis, Dimitrios Rakopoulos, Evangelia Mylona & Panagiotis Grammelis
The district heating (DH) system of Greece, mainly supported from lignite fired stations, is facing lately significant challenges. Stricter emission limits, decreased efficiency due to old age and increased costs are major challenges of the lignite sector and are expected to result in the decommissioning of several lignite-fired units in the coming years. As a result, managers of DH networks are currently investigating alternative scenarios for the substitution of thermal power that it is expected...

Regarding negative interrogatives in American English as argumentative structures

Pauline Levillain
This article investigates the use of negative interrogatives in English and provides new support as to why they can be regarded as argumentative structures (Heritage, 2002). Questions are usually described pragmatically as enabling the speaker to seek information. However, when they are negatively formulated, they are analysed in the literature as allowing the speaker to express their point of view: “negative interrogatives are treated as accomplishing assertions of opinion rather than questioning” (Heritage, 2002). This...

Culture, creativity, and conceptual dynamics: A structural hypothesis

Per Aage Brandt
We redefine the concept of concept and focus on its role in the intersubjective processes that characterize cultures and socio-cultural communities. Conceptual density determines communitary coherence, whereas highly variable conceptual velocity determines inter-conceptual dynamics within distinct conceptual fields of activity. Conflicts opposing force of conceptual authority by knowledge value and force of conceptual authority through social power lead to states of socio-cultural consensus or dissensus. A model of socio-cultural concept structure is proposed. The creativity...

PBL in Educational Psychology – Potentials and Challenges

Thomas Szulevicz & Mogens Jensen
This article discusses practical and theoretical aspects related to PBL. In the first section of the article, potentials related to professional training of forthcoming educational psychologists following PBL-principles are analyzed. It is argued that PBL constitutes a good platform for creating stimulating interplays between theory and practice. In the second section of the article we discuss some of the theoretical underpinnings in PBL. We discuss whether PBL is prone to a ‘form-content-dualism’, in which attention...

Transversal knowledge formations in Professional Bachelor Education employing Problem Based Learning (PBL)

Verner Larsen
This paper describes the principles underlying how various knowledge areas blend into transversal formations in two educational contexts employing PBL. Such ‘transversality’ has often been referred to as inter- cross- or trans-disciplinarity. However, these terms are ambiguous, especially in relation to Problem Based Learning. There is a growing need for stronger language to express underlying principles of knowledge formations and the constitution of such. The term transversality suggests that knowledge formations are not based on...

PBL and critical thinking disposition in Chinese medical students – A randomized cross-sectional study

XiangYun Du, Jeppe Emmersen, Egon Toft & Baozhi Sun
The purpose of this study was to explore the relationship of problem-based learning (PBL) and the development of critical thinking disposition (CT) and academic achievement in Chinese medical students using a cross-sectional randomized design. Medical students from China Medical University (CMU) were randomized to PBL or non-PBL teaching at the commencement of the study. After five years of study, CT was scored by a Chinese version of the California Critical Thinking Disposition Inventory (CCTDI-CV). The...

Using Problem-Based Learning to help Portuguese students make the Bologna transition

Manuel Cabral Reis, Emanuel Peres, Raul Morais & Joaquim Escola
The Bologna Declaration has opened a stage of big and deep changes in the internal university organization, external cooperation, teaching models and methods, among other., all over the European countries. Here we will present and discuss a pilot experience conducted at the Engineering Department of the University of Trás-os-Montes e Alto Douro, Portugal, during the second year of that transition period. In brief, we will present a set of non-mandatory courses proposed to the students...

Dimensions of problem based learning – dialogue and online collaboration in projects

Lars Birch Andreasen & Jørgen Lerche Nielsen
The article contributes to the discussions on problem based learning and project work, building on and reflecting the experiences of the authors. Four perspectives are emphasized as central to a contemporary approach to problem- and project-based learning: the exploration of problems, projects as a method, online collaboration, and the dialogic aspect of students’ project work. A specific focus is on how the problem- and project-based learning approach developed in Denmark historically and theoretically, and how...

Using Web 2.0 Technology to Enhance, Scaffold and Assess Problem-Based Learning

Catherine Hack
Web 2.0 technologies, such as social networks, wikis, blogs, and virtual worlds provide a platform for collaborative working, facilitating sharing of resources and joint document production. They can act as a stimulus to promote active learning and provide an engaging and interactive environment for students, and as such align with the philosophy of Problem-based Learning. Furthermore, Web 2.0 technologies can provide the tutor or facilitator with an opportunity to scaffold and asses the PBL process....

International Monetary Power and China’s Response

Hongyu Lin
International monetary power has become a new area of interest since the outbreak of the global financial crisis in 2008. The USA, the EU and China will pursue global monetary power in the future, and the USD, the EURO and the RMB will become the most important world reserve currencies. The pattern of international monetary power will shift from a unilateral-hegemony structure to a triangle-balance structure. This shift has a very strong influence on changes...

Ten Years of the Sino-European Strategic Partnership: Achievements and Problems

Mingjin Wang
Ten years after the establishment of the strategic partnership between China and the EU, this relationship has continued to flourish. However, publicly they have often been at odds, and even created doubts about the real existence of the comprehensive strategic partnership. The drawbacks of this relationship in recent years are mainly caused by the increased competitiveness in economy and trade, and the outbreak of quarrels concerning human rights and other areas. Since Sino-EU relations are...

A Dynamic Approach to the Analysis of Soft Power in International Relations

Chi Zhang
This article discusses soft power in international relations and the soft power of China’s foreign policy in recent years. After presenting a critique of the soft power theory developed by Joseph S. Nye, the paper provides an alternative interpretation of soft power. The author proposes a dynamic analysis of soft power in international relations, and argues that whether a power resource is soft or hard depends on the perceptions and feelings of various actors in...

Red Trojan Horses? A New Look at Chinese SOEs' Outward Investment

Yang Jiang
How dangerous is Chinese outward foreign direct investment (OFDI) because of the state's influence over business, particularly state-owned enterprises (SOEs)? To what extent are business and politics interwoven in Chinese investment decisions? Crucial knowledge is lacking on the relationship between the state and companies in China's OFDI. This study does not claim to completely refute the conventional view that Chinese companies, particularly SOEs, are controlled by the state in their OFDI activities. However, it tries...

Greening Africa-China Relations: African Agents Punching Below their Weight?

Negusu Aklilu
China is changing the global metabolism of goods and resources. In the last few decades, China has launched an unprecedented and unparalleled economic engagement with Africa. The level of Chinese investment on the continent is still very low relative to its investment in other regions whereas, for many African countries, China has already become the leading trading partner in terms of both import and export business. In fact, China has surpassed the U.S.A. as the...
