    Intelligent Design and Darwinian Evolution

    Get PDF
    Darwinian Evolution has many fundamental flaws that are only being discussed in the technical papers and yet it’s portrayed as an unequivocal theory. Intelligent Design is being censored In Academia and represented poorly in public media. Even with leading scientists at the forefront of discovery and logical reasoning Intelligent Design is portrayed as a religious way of infiltrating the science classroom but in reality its far from it. Ultimately it comes down to what the evidence points to and if it points to God then let it be so

    High Total Proton Conductivity in Large-Grained Yttrium-Doped Barium Zirconate

    Get PDF
    Barium zirconate has attracted particular attention among candidate proton conducting electrolyte materials for fuel cells and other electrochemical applications because of its chemical stability, mechanical robustness, and high bulk proton conductivity. Development of electrochemical devices based on this material, however, has been hampered by the high resistance of grain boundaries, and, due to limited grain growth during sintering, the high number density of such boundaries. Here, we demonstrate a fabrication protocol based on the sol−gel synthesis of nanocrystalline precursor materials and reactive sintering that results in large-grained, polycrystalline BaZr_(0.8)Y_(0.2O3−δ) of total high conductivity, 1 × 10^(−2) Scm^(−1) at 450 °C. The detrimental role of grain boundaries in these materials is confirmed via a comparison of the conductivities of polycrystalline samples with different grain sizes. Specifically, two samples with grain sizes differing by a factor of 2.3 display essentially identical grain interior conductivities, whereas the total grain boundary conductivities differ by a factor of 2.5−3.2, depending on the temperature (with the larger-grained material displaying higher conductivity)

    Emergence and resilience of cooperation in the spatial Prisoner's Dilemma via a reward mechanism

    Get PDF
    We study the problem of the emergence of cooperation in the spatial Prisoner's Dilemma. The pioneering work by Nowak and May showed that large initial populations of cooperators can survive and sustain cooperation in a square lattice with imitate-the-best evolutionary dynamics. We revisit this problem in a cost-benefit formulation suitable for a number of biological applications. We show that if a fixed-amount reward is established for cooperators to share, a single cooperator can invade a population of defectors and form structures that are resilient to re-invasion even if the reward mechanism is turned off. We discuss analytically the case of the invasion by a single cooperator and present agent-based simulations for small initial fractions of cooperators. Large cooperation levels, in the sustainability range, are found. In the conclusions we discuss possible applications of this model as well as its connections with other mechanisms proposed to promote the emergence of cooperation

    The Effects of Computer Assisted ESL Instruction on Limited English Proficient Students

    Get PDF
    A study was conducted to determine whether computer assisted instruction or the traditional ESL teaching method was more effective in teaching Limited English Proficient (LEP) students, English language proficiency. Twenty-two second grade subjects were separated into two groups at one elementary school in Yakima, Washington. The experimental group received computer assisted ESL instruction, while the control group was instructed with the traditional ESL teaching method. Analysis of the results supported the research hypotheses for one of the three dependent variables. The null hypothesis could not be rejected for a second variable, while for a third variable, a significant difference was found in the opposite direction

    Systemic intervention to manage ccomplexity in Mexican SMEs to last over time

    Get PDF
    The purpose of this research is to develop a new methodology based upon ideas on managing complexity from the Viable System Model. The context for the research is Small and medium-sized enterprises (SMEs) in Mexico. Worldwide, SMEs represent the segment of the economy that contributes the largest number of economic units and employees, both in industrialised countries and in those that are less developed. However, the astonishing rate of change today influences most human activities, including business organisations, and, therefore SMEs. Organisational complexity continues to grow as organisations are forced to address more issues and greater diversity in their operating environments. So, the current challenges imposed by modern-day complexity suggest to think about new ways of approaching managementpractice. The research aims to adopt systems thinking approaches applied on daily life as an ongoing process, based on a learning system which aims to increase the ability to manage complexity in SMEs to last over time. The research design is based on an action research approach developing a single case study intervention, based on Yin's work, in a Mexican SME in order to provide the empirical data. To do so, this work presents a novel model (ModK+) and multi-methodology (MetK+) as a way of thinking and acting, respectively, to perform a systemic intervention, linking the philosophical, methodological and practical levels. Finally, and based on the sources of evidence, the researcher realised two main findings. First, the MetK+ facilitated the adoption of systems thinking approaches in the daily practice of organisational management: it helped managers to identify and to overcome their main challenges and it enabled them to better manage their complexity. Second, the researcher identified the positive impact of building a learning system because it helped managers to refine their learning cycle to manage complexity; however, despite having such a learning system it was clear that managers would still require further accompaniment after the systemic intervention to overcome inertia in their busy daily agenda

    Ciencia y Teología en el Renacimiento paleólogo entre Oriente y Occidente: el caso de Isaac Argiro

    Get PDF
    Isaac Argiro (1310-1375 ca.) siguió la estela de su maestro, Nicéforo Gregorás, tanto en el cultivo de la ciencia profana como en la oposición a la teología de Gregorio Palamás, que Argiro combatió incluso en la persona del emperador Juan VI Cantacuceno. Además de esas inclinaciones espirituales, Isaac Argiro se interesó también por la astrología, como prueba el hecho de que copiara íntegro el Laurent. Plut. 28, 13, que fue el modelo de los manuscritos que se produjeron en el círculo de Juan Abramio, el astrólogo de Andrónico IV (Laurent. Plut. 28, 16, Marc. Gr. 324, Laurent. Plut. 28, 14 y Taurin. C. VII. 10). Esta comunicación trata de estudiar la vinculación entre el interés de Argiro por la astronomía y la astrología de la Grecia Antigua y sus posiciones filosóficas y teológicas, tal como fueron expresadas en sus opúsculos antipalamitas, así como su acercamiento a los círculos intelectuales bizantinos más proclives a un entendimiento con el Papado con vistas a la unión de las Iglesias de Roma y Constantinopla.Universidad de Málaga.
