Selected AbstractsThe Critical Role of the Underlayer Material and Thickness in Growing Vertically Aligned Carbon Nanotubes and Nanofibers on Metallic Substrates by Chemical Vapor DepositionADVANCED FUNCTIONAL MATERIALS, Issue 8 2010Gilbert D. Nessim Abstract Vertically aligned carbon nanotubes and nanofibers are grown on metallic Ta and Pd underlayers at temperatures below 500,°C. Controlling the size of the grains of the underlayer film is critical because this leads to a more uniform distribution of catalyst dots, which in turn results in vertical alignment of the carbon nanostructures. Rapid and limited heating and appropriate materials selection can also be used to limit catalyst/underlayer reactions that hinder or suppress carbon nanostructure growth or that lead to entangled growth. Control of catalyst reactivity with metallic underlayers is significant because growth on conductive substrates is notoriously difficult, but needed for many applications such as the use of carbon nanostructures in microelectronic circuits. [source] Geology and the London UndergroundGEOLOGY TODAY, Issue 1 2009Jonathan D. Paul Geology as a whole is the main influence on determining the feasibility of tunnelling for underground railways, and at what cost. Favourable conditions encouraged the early development of a network, significantly alter the methods used for construction, and are what form the tunnels, in terms of horizontal and vertical alignment. Local geology is shown, by means of two cross-sections following the tunnels, to be more important than the overall regional geology, where the underlying strata exhibit pronounced variations in permeability, and so mechanical properties. Geological complexities specific to the area of tunnelling generate problems during construction, but lead to technological innovation in the long term and a better understanding of local stratigraphy. As the result of this, and the increase in the quality of preliminary surveys, we are increasingly able to tunnel in areas previously considered treacherous. [source] Approaches to career success: An exploration of surreptitious career-success strategiesHUMAN RESOURCE MANAGEMENT, Issue 1 2006Lloyd C. Harris Theorists have forwarded a vast range of career-success determinants, including sociodemographic, social capital, personality, and other behavioral factors. We suggest that existing studies have overconcentrated on the overt behavioral determinants of career success to the detriment of the covert, clandestine, and concealed. Our analysis of two detailed qualitative case studies involving 112 indepth interviews with executives, managers, supervisors, and front-line staff in a large financial services organization and a medium-sized fashionable restaurant group uncovered five main strategies of surreptitious career success. These strategies are obligation creation and exploitation, personal-status enhancement, information acquisition and control, similarity exploitation, and proactive vertical alignment. Our findings indicate that just over 79% of those interviewed (88 of 112) referred to, at some point in their careers, premeditated strategies to enhance their careers that they concealed from coworkers. Consequently, we argue that surreptitious actions are central to employee career-focused activities and fundamental to a more complete understanding of the complexities of career-oriented employee behavior. © 2006 Wiley Periodicals, Inc. [source] Shared governance as vertical alignment of nursing group power and nurse practice council effectivenessJOURNAL OF NURSING MANAGEMENT, Issue 1 2009RICHARD J. BOGUE PhD Aim(s), This study validates an instrument for measuring the effectiveness of nursing practice councils and offers a framework for measuring and understanding shared governance. Background, Empowerment results from the vertical alignment of nursing group power with nursing unit power practices. The field lacks an instrument for measuring nurses' practice of power. Method(s), Two studies (n1 = 119; n2 = 248) are used to validate the Nursing Practice Council effectiveness scale (NPCes). Results, NPCes is a valid and reliable index of nursing practice council effectiveness. This study suggests specific diagnostic tools to understand two levels for actualized power, one at the group or departmental level and one at the unit level. Conclusion(s), NPCes and the Sieloff-King Assessment of Group Power within Organizations (SKAGPO) can be used together to improve examination of shared governance. Examining group power as well as unit-level practices may give a more complete view of barriers to nurse empowerment. Implications for nursing management, Changing nursing power and practices in an organization may be made more effective by engaging and monitoring vertical alignment of strategies fostering power competencies among nurse leaders and simultaneously supporting nursing practice councils as a means of exercising nurse authority at the unit level. [source] Vertically aligned polypyrrole drawing a fingerprint array prepared by electrochemical polymerization in chiral nematic electrolyteJOURNAL OF POLYMER SCIENCE (IN TWO SECTIONS), Issue 2 2006Hiromasa Goto A new electrochemical polymerization method for preparing vertically aligned polypyrrole drawing a fingerprint array was developed. Polymerization of Py in the chiral nematic liquid crystal (N*-LC) produces vertical alignment of the fibril structure. Here, the N*-LC plays a role of a molecular vessel. The fibril can grow with forming vertically aligned fibril structure along the fingerprint texture of N*-LC by electrochemical polymerization process. [source] | ||||||||||
