Science and the Scientist's Social Responsibility. Joseph Ben-David's, Roger Sperry's and Knut Erik Tranøy's Views of Science and the Scientist's Social Responsibility The aim of the study was to investigate, whether or not there is any connection between Jewish sociologist Joseph Ben-David's, American neuroscientist Roger Sperry's and Norwegian philosopher Knut Erik Tranøy's views of science and views of the scientist's social responsibility. The sources of information were their writings concerning this topic. Ben-David has a classical view of science. He thinks that the Mertonian norms of scientific activity, first written in 1942, are still valid in modern science. With the help of these norms Ben-David defends the view that science is morally neutral. Ben-David thinks that a scientist has a limited social responsibility. A scientist only reports on the new results, but he is not responsible for applying the results. In any case Ben-David's ideas are no longer valid. Sperry has a scientistic view of science. According to Sperry, science is the source of moral norms and also the best guide for moral action. The methods of natural sciences "show" how to solve moral problems. A scientist's personal views of science and social responsibility are not important. However Sperry's view is very problematic on the ethical side. Tranøy stresses the scientist's social responsibility. A scientist has common norms with the society from with he or she comes. This is why a scientist has the right, and also the responsibility, to discuss social and ethical questions between science and society. Tranøy's view has some ethical and practical problems, but it is valid in principle. Finally, Ben-David's, Sperry's and Tranøy's views of both science and the scientist's social responsibility have a connection: the view of science corresponds to the certain view of scientist's social responsibility. The result of this study is: Ben-David's, Sperry's and Tranøy's view of science have an ethical starting point as its fundamental presupposition, which include certain views of scientific knowledge, good and the scientist's ethical responsibilities. The connection between Ben-David's, Sperry's and Tranøy's views of science and views of the scientist's social responsibility means that their views of epistemology, meta-ethics and the scientist's ethical responsibilities have a connection to their views of the scientist's social responsibility. The results of this study can help the scientific community to organize the social responsibility of a scientist and deepen the conversation concerning the scientist's social responsibility.

Redefine: Runtime Reconfigurable Polymorphic ASIC

Emerging embedded applications are based on evolving standards (e.g., MPEG2/4, H.264/265, IEEE802.11a/b/g/n). Since most of these applications run on handheld devices, there is an increasing need for a single chip solution that can dynamically interoperate between different standards and their derivatives. In order to achieve high resource utilization and low power dissipation, we propose REDEFINE, a polymorphic ASIC in which specialized hardware units are replaced with basic hardware units that can create the same functionality by runtime re-composition. It is a ``future-proof'' custom hardware solution for multiple applications and their derivatives in a domain. In this article, we describe a compiler framework and supporting hardware comprising compute, storage, and communication resources. Applications described in high-level language (e.g., C) are compiled into application substructures. For each application substructure, a set of compute elements on the hardware are interconnected during runtime to form a pattern that closely matches the communication pattern of that particular application. The advantage is that the bounded CEs are neither processor cores nor logic elements as in FPGAs. Hence, REDEFINE offers the power and performance advantage of an ASIC and the hardware reconfigurability and programmability of that of an FPGA/instruction set processor. In addition, the hardware supports custom instruction pipelining. Existing instruction-set extensible processors determine a sequence of instructions that repeatedly occur within the application to create custom instructions at design time to speed up the execution of this sequence. We extend this scheme further, where a kernel is compiled into custom instructions that bear strong producer-consumer relationship (and not limited to frequently occurring sequences of instructions). Custom instructions, realized as hardware compositions effected at runtime, allow several instances of the same to be active in parallel. A key distinguishing factor in majority of the emerging embedded applications is stream processing. To reduce the overheads of data transfer between custom instructions, direct communication paths are employed among custom instructions. In this article, we present the overview of the hardware-aware compiler framework, which determines the NoC-aware schedule of transports of the data exchanged between the custom instructions on the interconnect. The results for the FFT kernel indicate a 25% reduction in the number of loads/stores, and throughput improves by log(n) for n-point FFT when compared to sequential implementation. Overall, REDEFINE offers flexibility and a runtime reconfigurability at the expense of 1.16x in power and 8x in area when compared to an ASIC. REDEFINE implementation consumes 0.1x the power of an FPGA implementation. In addition, the configuration overhead of the FPGA implementation is 1,000x more than that of REDEFINE.

Joseph A. Schumpeter's Theory of Social and Economic Evolution : a Reconstruction and Critique

The book presents a reconstruction, interpretation and critical evaluation of the Schumpeterian theoretical approach to socio-economic change. The analysis focuses on the problem of social evolution, on the interpretation of the innovation process and business cycles and, finally, on Schumpeter s optimistic neglect of ecological-environmental conditions as possible factors influencing social-economic change. The author investigates how the Schumpeterian approach describes the process of social and economic evolution, and how the logic of transformations is described, explained and understood in the Schumpeterian theory. The material of the study includes Schumpeter s works written after 1925, a related part of the commentary literature on these works, and a selected part of the related literature on the innovation process, technological transformations and the problem of long waves. Concerning the period after 1925, the Schumpeterian oeuvre is conceived and analysed as a more or less homogenous corpus of texts. The book is divided into 9 chapters. Chapters 1-2 describe the research problems and methods. Chapter 3 is an effort to provide a systematic reconstruction of Schumpeter's ideas concerning social and economic evolution. Chapters 4 and 5 focus their analysis on the innovation process. In Chapters 6 and 7 Schumpeter's theory of business cycles is examined. Chapter 8 evaluates Schumpeter's views concerning his relative neglect of ecological-environmental conditions as possible factors influencing social-economic change. Finally, chapter 9 draws the main conclusions.

Influence of viscoelastic nature on the intermittent peel-front dynamics of adhesive tape

We investigate the influence of viscoelastic nature of the adhesive on the intermittent peel front dynamics by extending a recently introduced model for peeling of an adhesive tape. As time and rate-dependent deformation of the adhesives are measured in stationary conditions, a crucial step in incorporating the viscoelastic effects applicable to unstable intermittent peel dynamics is the introduction of a dynamization scheme that eliminates the explicit time dependence in terms of dynamical variables. We find contrasting influences of viscoelastic contribution in different regions of tape mass, roller inertia, and pull velocity. As the model acoustic energy dissipated depends on the nature of the peel front and its dynamical evolution, the combined effect of the roller inertia and pull velocity makes the acoustic energy noisier for small tape mass and low-pull velocity while it is burstlike for low-tape mass, intermediate values of the roller inertia and high-pull velocity. The changes are quantified by calculating the largest Lyapunov exponent and analyzing the statistical distributions of the amplitudes and durations of the model acoustic energy signals. Both single and two stage power-law distributions are observed. Scaling relations between the exponents are derived which show that the exponents corresponding to large values of event sizes and durations are completely determined by those for small values. Th scaling relations are found to be satisfied in all cases studied. Interestingly, we find only five types of model acoustic emission signals among multitude of possibilities of the peel front configurations.

Analysis of the Genome and Transcriptome of Cryptococcus neoformans var. grubii Reveals Complex RNA Expression and Microevolution Leading to Virulence Attenuation

Cryptococcus neoformans is a pathogenic basidiomycetous yeast responsible for more than 600,000 deaths each year. It occurs as two serotypes (A and D) representing two varieties (i.e. grubii and neoformans, respectively). Here, we sequenced the genome and performed an RNA-Seq-based analysis of the C. neoformans var. grubii transcriptome structure. We determined the chromosomal locations, analyzed the sequence/structural features of the centromeres, and identified origins of replication. The genome was annotated based on automated and manual curation. More than 40,000 introns populating more than 99% of the expressed genes were identified. Although most of these introns are located in the coding DNA sequences (CDS), over 2,000 introns in the untranslated regions (UTRs) were also identified. Poly(A)-containing reads were employed to locate the polyadenylation sites of more than 80% of the genes. Examination of the sequences around these sites revealed a new poly(A)-site-associated motif (AUGHAH). In addition, 1,197 miscRNAs were identified. These miscRNAs can be spliced and/or polyadenylated, but do not appear to have obvious coding capacities. Finally, this genome sequence enabled a comparative analysis of strain H99 variants obtained after laboratory passage. The spectrum of mutations identified provides insights into the genetics underlying the micro-evolution of a laboratory strain, and identifies mutations involved in stress responses, mating efficiency, and virulence.

Bioenergy and climate change mitigation: an assessment

Bioenergy deployment offers significant potential for climate change mitigation, but also carries considerable risks. In this review, we bring together perspectives of various communities involved in the research and regulation of bioenergy deployment in the context of climate change mitigation: Land-use and energy experts, land-use and integrated assessment modelers, human geographers, ecosystem researchers, climate scientists and two different strands of life-cycle assessment experts. We summarize technological options, outline the state-of-the-art knowledge on various climate effects, provide an update on estimates of technical resource potential and comprehensively identify sustainability effects. Cellulosic feedstocks, increased end-use efficiency, improved land carbon-stock management and residue use, and, when fully developed, BECCS appear as the most promising options, depending on development costs, implementation, learning, and risk management. Combined heat and power, efficient biomass cookstoves and small-scale power generation for rural areas can help to promote energy access and sustainable development, along with reduced emissions. We estimate the sustainable technical potential as up to 100EJ: high agreement; 100-300EJ: medium agreement; above 300EJ: low agreement. Stabilization scenarios indicate that bioenergy may supply from 10 to 245EJyr(-1) to global primary energy supply by 2050. Models indicate that, if technological and governance preconditions are met, large-scale deployment (>200EJ), together with BECCS, could help to keep global warming below 2 degrees degrees of preindustrial levels; but such high deployment of land-intensive bioenergy feedstocks could also lead to detrimental climate effects, negatively impact ecosystems, biodiversity and livelihoods. The integration of bioenergy systems into agriculture and forest landscapes can improve land and water use efficiency and help address concerns about environmental impacts. We conclude that the high variability in pathways, uncertainties in technological development and ambiguity in political decision render forecasts on deployment levels and climate effects very difficult. However, uncertainty about projections should not preclude pursuing beneficial bioenergy options.

Apuntes en torno al pensamiento político de Joseph Ratzinger

Un ameno libro de circunstancia sobre la elección de Benedicto XVI, publicado apenas un mes después de esta, me servirá para iniciar mi exposición sobre la persona y labor de Joseph Ratzinger. Allí el autor, Alfredo Urdaci, ensaya una interesante tesis, ¿cómo fue posible tal elección? Porque si bien Ratzinger estaba entre los papables, no era muy probable que realmente fuera elegido. Tenía y –por qué no decirlo– sigue teniendo oposición dentro de la Curia y dentro de algunos sectores de la Iglesia. Y cómo no habría de levantarla un cardenal tan políticamente incorrecto como Ratzinger. No me detengo en sus distintas declaraciones a lo largo de su carrera, pero sí me gustaría presentar un par de frases suyas dichas tan solo días antes de su elección como Papa.

Determination Ofinterfacial Mechanical Parameters For An Al/Epoxy/Al2O3 System Byusing Peel Test Simulations

Peel test measurements and simulations of the interfacial mechanical parameters for the Al/Epoxy/Al2O3 system are performed in the present investigation. A series of Al film thicknesses between 20 and 250 microns and three peel angles of 90, 135 and 180 degrees are considered. Two types of epoxy adhesives are adopted to obtain both strong and weak interface adhesions. A finite element model with cohesive zone elements is used to identify the interfacial parameters and simulate the peel test process. By simulating and recording normal stress near the crack tip, the separation strength is obtained. Furthermore, the cohesive energy is identified by comparing the simulated steady-state peel force and the experimental result. It is found from the research that both the cohesive energy and the separation strength can be taken as the intrinsic interfacial parameters which are dependent on the thickness of the adhesive layer and independent of the film thickness and peel angle.

Determination of interface properties between micron-thick metal film and ceramic substrate using peel test

Peel test measurements have been performed to estimate both the interface toughness and the separation strength between copper thin film and Al2O3 substrate with film thicknesses ranging between 1 and 15 mu m. An inverse analysis based on the artificial neural network method is adopted to determine the interface parameters. The interface parameters are characterized by the cohesive zone (CZ) model. The results of finite element simulations based on the strain gradient plasticity theory are used to train the artificial neural network. Using both the trained neural network and the experimental measurements for one test result, both the interface toughness and the separation strength are determined. Finally, the finite element predictions adopting the determined interface parameters are performed for the other film thickness cases, and are in agreement with the experimental results.

El problema de la razón moderna y el estado de derecho según Joseph Ratzinger

Resumen: El presente texto analiza dos cuestiones centrales en el pensamiento de Joseph Ratzinger: por un lado, el problema de la racionalidad del derecho y, en segundo lugar, el fundamento del Estado de Derecho en el mundo moderno. Para tal fin, previo diagnóstico sobre la situación jurídica contemporánea, se analizan ambos tópicos de acuerdo a los principales discursos realizados por el Cardenal Ratzinger y luego papa Benedicto XVI llegando a la conclusión de que el problema subyacente a ambos es el problema de la verdad tanto metafísica como moral.

Voz sagrada, política, rhetorica, e metrica ou supplemento a's Vozes Saudosas da eloquencia do espirito, do zelo, e eminente sabedoria do Padre Antonio Vieira da Companhia de Jesus, pregador de S. Magestade, e príncipe dos oradores evangélicos : offerecida ao Senhor Doutor Joseph de Lima Pinheiro e Aragam

Padre Antônio Vieira nasceu em Lisboa em 6 de novembro de 1608 e morreu na Bahia em 18 de julho de 1697. Ordenado sacerdote em 1634, logo se destacou como excepcional pregador. Exerceu importante papel politico e diplomático durante o reinado de D. João IV e fez do púlpito uma tribuna a serviço da nação, em guerra com a Espanha. De 1652 a 1661 atuou como missionário no Maranhão. Em Portugal foi denunciado como herético ao Tribunal da Inquisição. Doente e encarcerado defendeu-se com extraordinário vigor, mas foi condenado a internamento numa casa jesuítica e proibido de pregar. Retirou-se em 1681 para o Brasil, onde trabalhou na edição completa dos Sermoens, iniciada em 1679. Voz sagrada... é um suplemento às Vozes saudosas. Foi publicado, após a morte do autor, por Francisco Luiz Ameno em 1748. Compõe-se de cartas, poemas e outros escritos em latim e português e uma oração fúnebre celebrada pelo Conde da Ericeira nas exéquias do Padre Vieira
