Strengthening Creative Problem-Solving within Upper-Elementary Science Education

This intervention study examined the effectiveness of instructional support tailored toward two techniques (i.e., random associations and constraint identification) to strengthen children's creative problem-solving skills within upper-elementary science education. Five inquiry-based science lessons with ample opportunity for creative problem-solving (i.e., divergent and convergent thinking) were provided. Children were assigned to a condition with instructional support (n = 107) or without (n = 134). Domain-general and specific measures of divergent and convergent thinking were included, and reading comprehension as well as mathematical ability were taken into account. Repeated measures multivariate analyses of covariance revealed how all children improved in terms of domain-general convergent thinking, with a larger increase for children who performed better in mathematics. This shows a promising premise for future research focusing on the domain generality of convergent thinking and for the potential of transfer across domains. No additional improvement based on instructional support was found and children did not improve in terms of divergent thinking. The constraint identification and random associations technique might not be suitable for elementary school children, yet future research is necessary to validate such claims. Meanwhile, teachers could possibly support convergent thinking by simply providing exercises for divergent and convergent thinking.     

What is the Philosophy of Information?

Computational and information-theoretic research in philosophy has become increasingly fertile and pervasive, giving rise to a wealth of interesting results. In consequence, a new and vitally important field has emerged, the philosophy of information (PI). This essay is the first attempt to analyse the nature of PI systematically. PI is defined as the philosophical field concerned with the critical investigation of the conceptual nature and basic principles of information, including its dynamics, utilisation, and sciences, and the elaboration and application of information-theoretic and computational methodologies to philosophical problems. I argue that PI is a mature discipline for three reasons: it represents an autonomous field of research; it provides an innovative approach to both traditional and new philosophical topics; and it can stand beside other branches of philosophy, offering a systematic treatment of the conceptual foundations of the world of information and the information society.     

Protecting God from Science and Technology: How Religious Criticisms of Biotechnologies Backfire

Many religious critics argue that biotechnology (such as cloning and genetic engineering) intrudes on God's domain, or plays God, or revolts against God. While some of these criticisms are standard complaints about human hubris, I argue that some of the recent criticism represents a "Promethean" concern, in which believers unreflectively seem to fear that science and technology are actually replicating or stealing God's special deity–defining powers. These criticisms backfire theologically, because they diminish God, portraying God as an anthropomorphic superbeing whose relevance and special nature are increasingly rivaled by human power.     

Hertz and Wittgenstein's Philosophy of Science

The German physicist Heinrich Hertz played a decisive role for Wittgenstein's use of a unique philosophical method. Wittgenstein applied this method successfully to critical problems in logic and mathematics throughout his life. Logical paradoxes and foundational problems including those of mathematics were seen as pseudo-problems requiring clarity instead of solution. In effect, Wittgenstein's controversial response to David Hilbert and Kurt Gödel was deeply influenced by Hertz and can only be fully understood when seen in this context. To comprehend the arguments against the metamathematical programme, and to appreciate how profoundly the philosophical method employed actually shaped the content of Wittgenstein's philosophy, it is necessary to make an intellectual biographical reconstruction of their philosophical framework, tracing the Hertzian elements in the early as well as in the later writings. In order to write Wittgenstein's biography, we have to take seriously the coherence of his thought throughout his life, and not let convenient philosophical ideologies be our guidance in drawing up a “Wittgensteinian philosophy”. To do so, we have to take a second look upon what he actually wrote, not only in the already published material, but in the entire Nachlass. Clearly, this is not easily done, but it is a necessary task in the historical reconstruction of Wittgenstein's life and work.     

Anforderungen an eine physikalische Fundamentaltheorie

Requirements for a Fundamental Physical Theory. The search for a so-called ‘Theory of Everything’ which should lead to the unification of all fundamental forces is seen, at present, as a matter of priority within theoretical high-energy physics. Some physicist identify this Theory of Everything today with aspecific type of superstring theory or its intended conceptual continuation, called M-Theory. The objective of this article is the discussion of the requirements a fundamental physical theory has to comply with. This question can only be clarified if one takes into account that the claim that a physical theory is all-encompassing takes forgranted some tacit prerequisites which concern the conceptual and epistemological foundations of science and, not least, the question for the realizability of its reductionistic unity. This revised version was published online in August 2006 with corrections to the Cover Date.     

Cross-fertilization versus transmission: Recommendations for developing a bidirectional approach to psychotherapy dissemination research

Psychotherapy researchers are increasingly engaged in collaborations with clinical practitioners and mental health administrators. Each party brings its own perspectives, values, and agendas to bear in these encounters. Viable research—practice collaborations depend on understanding and negotiating some of the tensions in these relationships. In this article, we discuss the contexts that prevail for various participants in a psychotherapy dissemination study as well as the values, goals, costs, and benefits related to research participation. This article is a collaboration among the researchers, mental health administrators, therapists, and clients involved in an ongoing treatment dissemination study. Our recommendations for research—practice collaborations are based on our experiences and dialogues over the course of this study.

Overcoming Barriers to Collaboration Between Basic Behavioral Scientists and Public Health Scientists in Research on Mental Disorders

The behavioral and public health sciences both have a long and rich history supporting basic, translational, and applied research aimed at improving human lives and reducing human suffering. Through the complementary expertise of these disciplines, investigators have contributed to significant, worldwide improvements in mental and physical health. Further gains can be achieved through collaborative research among scientists in these 2 fields. Unfortunately, there are a number of barriers to such collaboration originating in different intellectual traditions, research methods, and the structure and values of academia. We identify these barriers and potential strategies for overcoming them. Several areas for future collaborative research appear promising, especially comorbid mental and physical disorders, adherence to interventions, stigma, and emotional processes. Theory-guided preventive interventions may represent especially fertile areas of collaborative effort.
