Characterization of silicon nanowire by use of full-vectorial finite element method.

We have carried out a rigorous H-field-based full-vectorial modal analysis and used it to characterize, more accurately, the abrupt dielectric discontinuity of a high index contrast optical waveguide. The full-vectorial H and E fields and the Poynting vector profiles are described in detail. It has been shown through this work that the mode profile of a circular silicon nanowire is not circular and also contains a strong axial field component. The single-mode operation, vector field profiles, modal hybridness, modal ellipticity, and group velocity dispersion of this silicon nanowire are also presented

Stochastic cycle selection in active flow networks

Active biological flow networks pervade nature and span a wide range of scales, from arterial blood vessels and bronchial mucus transport in humans to bacterial flow through porous media or plasmodial shuttle streaming in slime molds. Despite their ubiquity, little is known about the self-organization principles that govern flow statistics in such nonequilibrium networks. Here we connect concepts from lattice field theory, graph theory, and transition rate theory to understand how topology controls dynamics in a generic model for actively driven flow on a network. Our combined theoretical and numerical analysis identifies symmetry-based rules that make it possible to classify and predict the selection statistics of complex flow cycles from the network topology. The conceptual framework developed here is applicable to a broad class of biological and nonbiological far-from-equilibrium networks, including actively controlled information flows, and establishes a correspondence between active flow networks and generalized ice-type models.

Stochastic cycle selection in active flow networks.

Active biological flow networks pervade nature and span a wide range of scales, from arterial blood vessels and bronchial mucus transport in humans to bacterial flow through porous media or plasmodial shuttle streaming in slime molds.

The Ripple Effects When a Refugee Camp Becomes a University Town: University Teacher Education in Dadaab, Kenya

Dadaab, Kenya is the site of the first university teacher education program created by a consortium of institutions (UBC, York, Moi, Kenyatta) within the Borderless Higher Education for Refugees. Dadaab is also the host town to what has been described as the largest protracted refugee camp, at its peek nearly a half million residents. Here, four program graduates, who are secondary school teachers in Daddab tell their stories of the impact that their education diploma and degrees have had on them and their communities. Their stories are of leadership, resilience, and hope

Transformational leadership influences on organisational justice and employee commitment in a customer service organisation

Orientation: Organisations are facing several challenges pertaining to effective leadership, fairness and loyalty of employees. The moderating influence of transformational leadership (TL) on the relationship between justice and employee commitment is still largely unknown and needs to be explored further, especially within the customer service industry. Research purpose: The aim of this study was to determine the relationship between organisational justice and employee commitment and to examine the moderating effect of TL on the relationship between organisational justice and employee commitment in a customer service organisation. Motivation for the study: The research setting of this study is a customer service organisation. This organisation calls for a role model leadership approach, such as TL, to create a just, fair workplace and ultimately increase the level of employee commitment. Research approach/design and method: A quantitative cross-sectional survey design was used to collect the data from a sample of 111 permanently employed staff in a South African customer service organisation. Main findings: The findings indicate that TL had a significant positive relationship with organisational justice and employee commitment. Furthermore, the results indicate that TL moderated the relationship between organisational justice and employee commitment. Practical/managerial implications: The findings showed that TL could be vital as an effective leadership approach that can enhance justice perceptions and psychological attachment in the workplace. Contribution/value-add: This study contributes to the theoretical debate on TL, workplace fairness and psychological attachment by providing empirical support on the effect of TL on the relationship between justice and commitment perceptions
