ABSTRACTThe interface between Hg1-xCdxTe(0 ≦ x ≦ 1) and Hg1-yCdyTe(0 ≦ y ≦ 1) epitaxial layers of different composition (x ≠ y) is unstable with regard to the intermixing of the Hg and Cd cations within the Group II sublattice. This phenomenon may give rise to long-term stability problems in HgTe-(Hg,Cd)Te superlattices and composition grading between (Hg,Cd)Te absorber layers and CdTe buffer or passivation layers in epitaxial infra red detectors. In this paper, a novel approach to the inhibition of interdiffusion in these systems is discussed. This involves the growth of an intervening ZnTe barrier layer at the heterointerface between two (Hg,Cd)Te layers. Initial results are presented which indicate the effectiveness of this technique in reducing interdiffusion in an experimental heterostructure grown by MOVPE. Some possible applications in a variety of HgTe-based long wavelength devices are discussed.

Beginning in the summer of 2015, research was conducted on protective wood coatings and accelerated weathering testing methods for architectural log and timber. A rack for supplementary natural weathering testing of hydrophobic and ultraviolet protective surface treatments for logs was also erected as a subsequent phase at Grand Teton National Park. This laboratory and field research is part of an ongoing project to develop an appropriate treatment for historic log structures in the region that will preserve their original fabric while maintaining the intended historic appearance of the buildings, i.e., unpainted. The weathering rack will be in place for upwards of five years to verify the lab-based results from Phase I and to determine the long-term durability of the chosen treatments on already aged materials in situ. This report addresses the methods and materials for preparation of the weathering rack and samples as well as the methods being used to monitor their progress and initial results. Readings will be taken yearly to monitor the effects of weathering on each treatment.

The purpose of this paper is to draw attention to results achieved in selected neurotic cases treated by short-term abreactive techniques in St. Clement's Hospital during recent months. Patients usually stay in for about two months; as yet it is too early to assess long-term results of this form of treatment, but it is felt that some of the initial results are extremely encouraging.

Engaging in ongoing assessment is key to libraries demonstrating their value to their institutions. This study is an initial step in a STEM library’s long-term goal of measuring the library’s connection to, and impact on, student academic success markers such as retention and persistence. Initial results showed that any library usage was always accompanied by a slightly higher achievement in GPA for the user. Results will serve as benchmarks for further study.

This article addresses some fundamental affinities between theatre and teaching and is based on emerging work in a long-term experiment which we began in the conference ‘Weber/Simmel Antagonisms: Staged Dialogues’, held at the University of Edinburgh on December 2015. Aimed at exploring the possibilities of the theatrical and dialogical forms for teaching the classics of social and cultural theory, it is a risky experiment whose initial results are presented in this special issue. In order to introduce the dialogues and situate them in the context of the broader project, the article does three things: first, it expounds the process of subjectivation at work in both theatre and teaching and explores some of the modalities of the subjective shift sought for in the public and students. Second, it explains the specificity of this experiment by contrasting it with other uses of theatrical dialogue in teaching. Finally, before briefly introducing each of the dialogues, the article clarifies the fundamental difference between the dialogical form and debate, as radically separating them is at the heart of any experiment in subjectivation, away from the stirring of opinions.

This paper discusses the knowledge transfer process in offshore outsourcing. The focus is a case study of software offshore outsourcing from Japan to Vietnam. Initial results confirm that willingness to cooperate and good impressions facilitate the knowledge transfer process. In addition, communication barriers, cultural differences, lack of equivalence in individual competence, and lack of common rules slow down the transfer process. The study also identifies the Bridge System Engineer (Bridge SE)-a type of coordinator who mediates and enhances the relationship between Japanese clients and Vietnamese service providers. Employing a Bridge SE is an effective way to fill the communication gap, the cultural gap, and generally improve the business relationship. Bridge SEs use their background of higher education and long-term residence in Japan to give advice to Vietnamese software teams on Japanese cultural characteristics, such as the apology culture and the separation between work and private time. In other situations, Bridge SEs use their IT background and communication skills to verify and adjust communication contents before information is sent from one side to another.
