Sztuka i dobór naturalny

The relation between art and the idea of natural selection makes the key issue of this paper. The author examines how Charles Darwin's conc ept of evolution might have affected the sphere of aesthetics. However, the author arguments against understanding of art as a side product of human progress and takes it as an independent form of human agency. The critique of various evolutionary standpoints laid out in this article holds to the standpoint that we cannot recreate with other means the moments of pleasure delivered by art. Thus it is extremely important to understand art as a form of human creativity and a neces sary part of our existence beyond biological determinism stressed out by many evolutionary thinkers

STM Studies of Synthetic Peptide Monolayers

We have used scanning probe microscopy to investigate self-assembled monolayers of chemically synthesized peptides. We find that the peptides form a dense uniform monolayer, above which is found a sparse additional layer. Using scanning tunneling microscopy, submolecular resolution can be obtained, revealing the alpha helices which constitute the peptide. The nature of the images is not significantly affected by the incorporation of redox cofactors (hemes) in the peptides.Comment: 4 pages, 3 figures (4 gifs); to appear in the Proceedings of the XIIth Int.

The Role of Task and Process Conflict in Strategizing

The implementation of strategic initiatives is central to organizational success because it involves not just the execution of strategy, but also the formulation of strategy content. Yet, strategy implementation is complex, partially because it is critically affected by human dynamics. These dynamics are an integral but poorly understood aspect of how organizations negotiate multiple goals. Conflict is one dynamic that has received little attention in the context of strategy implementation. The authors address this gap by studying task and process conflict as a firm implements a strategy in real time. The study demonstrates that process conflict directs attention to problems with how to implement a strategy, while task conflict directs attention to problems with the content of the strategy. Critically, however, managers can only harness generative effects of conflict if they correctly diagnose process and task conflict, and respond to both forms of conflict. This requires an understanding of the entwined nature of task and process conflict, and highlights the necessity of aligning responses to these forms of conflict. Thus, this study offers conflict as one explanatory mechanism of how actors execute strategy and clarify strategy content

Magnetoelastic coupling in the stretched diamond lattice of TbTaO 4 †

The magnetic structure of diamond-like lattice has been studied extensively in terms of the magnetic frustration. Here we report the distortion of stretched diamond lattice of Tb3+ (4f8) in M–TbTaO4 on application of a magnetic field. We have investigated the structural and magnetic properties of M phase terbium tantalate M–TbTaO4 as a function of temperature and magnetic field using magnetometry and powder neutron diffraction. Sharp λ-shape transitions in d(χT)/dT, dM/dH and specific heat data confirm the previously reported three-dimensional (3D) antiferromagnetic ordering at TN ∼ 2.25 K. On application of a magnetic field the Néel temperature is found to decrease and variable field neutron diffraction experiments below TN at 1.6 K show an increase in both the bond and angle distortion of the stretched diamond lattice with magnetic field, indicating a potential magneto-elastic coupling effect. By combining our magnetometry, heat capacity and neutron diffraction results we generate a magnetic phase diagram for M–TbTaO4 as a function of temperature and field

The twilight of the Liberal Social Contract? On the Reception of Rawlsian Political Liberalism

This chapter discusses the Rawlsian project of public reason, or public justification-based 'political' liberalism, and its reception. After a brief philosophical rather than philological reconstruction of the project, the chapter revolves around a distinction between idealist and realist responses to it. Focusing on political liberalism’s critical reception illuminates an overarching question: was Rawls’s revival of a contractualist approach to liberal legitimacy a fruitful move for liberalism and/or the social contract tradition? The last section contains a largely negative answer to that question. Nonetheless the chapter's conclusion shows that the research programme of political liberalism provided and continues to provide illuminating insights into the limitations of liberal contractualism, especially under conditions of persistent and radical diversity. The programme is, however, less receptive to challenges to do with the relative decline of the power of modern states

The state of the Martian climate

60°N was +2.0°C, relative to the 1981–2010 average value (Fig. 5.1). This marks a new high for the record. The average annual surface air temperature (SAT) anomaly for 2016 for land stations north of starting in 1900, and is a significant increase over the previous highest value of +1.2°C, which was observed in 2007, 2011, and 2015. Average global annual temperatures also showed record values in 2015 and 2016. Currently, the Arctic is warming at more than twice the rate of lower latitudes

Family physicians\u27 professional identity formation: a study protocol to explore impression management processes in institutional academic contexts.

BACKGROUND: Despite significant differences in terms of medical training and health care context, the phenomenon of medical students\u27 declining interest in family medicine has been well documented in North America and in many other developed countries as well. As part of a research program on family physicians\u27 professional identity formation initiated in 2007, the purpose of the present investigation is to examine in-depth how family physicians construct their professional image in academic contexts; in other words, this study will allow us to identify and understand the processes whereby family physicians with an academic appointment seek to control the ideas others form about them as a professional group, i.e. impression management. METHODS/DESIGN: The methodology consists of a multiple case study embedded in the perspective of institutional theory. Four international cases from Canada, France, Ireland and Spain will be conducted; the \u22case\u22 is the medical school. Four levels of analysis will be considered: individual family physicians, interpersonal relationships, family physician professional group, and organization (medical school). Individual interviews and focus groups with academic family physicians will constitute the main technique for data generation, which will be complemented with a variety of documentary sources. Discourse techniques, more particularly rhetorical analysis, will be used to analyze the data gathered. Within- and cross-case analysis will then be performed. DISCUSSION: This empirical study is strongly grounded in theory and will contribute to the scant body of literature on family physicians\u27 professional identity formation processes in medical schools. Findings will potentially have important implications for the practice of family medicine, medical education and health and educational policies
