The First World War between Memory and History: A Conference Retrospective

Long after the guns of the First World War went silent on 11 November 1918, the war continues to spark debate. The many points of contention were on full display at the “From Memory to History” conference, hosted by Western University in London, Ontario, over three days in November 2011. Scholars and enthusiasts from around the world gathered to share, debate, and ultimately demonstrate that the war’s many legacies are still open to interpretation, even as the centenary of the war’s outbreak approaches. Perhaps the most crucial lesson learned is that both memory and history are malleable concepts, prone to revision, and there are numerous narratives in many disciplines that remain untold, even with an event as well-documented as the First World War

Automated Classification of Transient Contamination in Stationary Acoustic Data

An automated procedure for the classification of transient contamination of stationary acoustic data is proposed and analyzed. The procedure requires the assumption that the stationary acoustic data of interest can be modeled as a band-limited, Gaussian random process. It also requires that the transient contamination be of higher variance than the acoustic data of interest. When these assumptions are satisfied, it is a blind separation procedure, aside from the initial input specifying how to subdivide the time series of interest. No a priori threshold criterion is required. Simulation results show that for a sufficient number of blocks, the method performs well, as long as the occasional false positive or false negative is acceptable. The effectiveness of the procedure is demonstrated with an application to experimental wind tunnel acoustic test data which are contaminated by hydrodynamic gusts

Cultural competence – transforming policy, services, programs and practice

This chapter discusses some of the complex issues surrounding the notion of cultural competence—and the critical need for practitioners to develop knowledge, skills, understandings and attributes to be responsive in diverse cultural settings. The argument for culturally competent mental health practitioners and services is situated within a human rights framework which underpins the principles, standards and practice frameworks intended to facilitate/contribute to the capacity and empowerment of mental health practitioners and clients, families and communities. The National Practice Standards for the Mental Health Workforce 2013 (the practice standards) outline core competencies (including cultural competence) regarded as essential for the mental health workforce: mental health nursing, occupational therapy, psychiatry, psychology and social work. The documented impact of these disciplines/professions on Aboriginal people requires new ways of working that are empowering, respectful and ethical. A case is made for the importance of practitioners providing more culturally inclusive and appropriate care to increase the likelihood that clients and their carers will experience a sense of cultural safety (as well as culturally appropriate services) for Aboriginal clients, their families and communities. The practice standards are complemented by professional guidelines and the National Standards for Mental Health Services 2010 (the service standards). This chapter provides a range of tools and strategies and a Critical Reflection Framework for Analysis to assist students or practitioners to adopt a critical standpoint in order to develop key competencies (knowledge, skills, attitudes and values) to be culturally respectful and effective in their practice in Aboriginal and Torres Strait Islander mental health. Equally important is the need for strategies for self-care and support such as mentoring, journaling, peer support, counselling and engaging in self-reflective, transformative practice.&nbsp

Information Security Trends and Issues in the Moodle E-Learning Platform: An Ethnographic Content Analysis

Empirical research on information security trends and practices in e-learning is scarce. Many articles that have been published apply basic information security concepts to e-learning and list potential threats or propose frameworks for classifying threats. The purpose of this research is to identify, categorize and understand trends and issues in information security in e-learning as reflected in the discussions on a ‘Security and Privacy’ discussion forum of the Moodle learning management system. Four primary themes were identified, as two-thirds of the security related threads on the discussion board addressed the following topics: authentication, permissions, attacks and Moodle configuration. This study should be of interest to educators in information systems management on several levels. First of all, as users and in some cases ad-hoc administrators of learning management systems, the themes and trends identified should increase awareness of security issues inherent in the platform. Secondly, this article serves as a descriptive case study on how security issues are described, discussed and dealt with by developers, users and administrators within the open source software development paradigm

Solid Lubrication Bearing Design Through Analytical and Empirical Vibration Analysis of Characteristic Frequencies

Ball bearings with solid lubrication lack the damping mechanisms of oil and produce well-defined vibration characteristics based upon given geometry and speed of operation. This work takes advantage of the high signal to noise ratio in x-ray bearings and develops an algorithm to statistically track bearing performance based upon fundamental bearing theory, Monte Carlo simulation, Order Analysis, and Weibull statistics. The technique gathers vibration data solely related to the theoretical operation of a bearing, negates the background noise, and provides descriptive vibration amplitude statistics of individual bearing components for evaluation. The practical implications of the thesis described herein allow the bearing engineer to optimize designs for life and noise by essentially tracking bearing component condition during operation. The output of the research is a tool/methodology to study and describe the vibration pattern of a bearing in operation. The concepts are tested and verified through the creation of a vibration transfer function between a sub-assembly bearing test rig and a bearing at full assembly level. Developed with Weibull statistics, the function correctly describes populations of vibration amplitude approximately 50% of the time within a 72% confidence interval. This was possible because the statistical methodology created found physically meaningful vibration patterns, not random vibration patterns

Evaluation of Upper Airway Changes Following Surgical Removal of the Adenoids Using 3-D Cone Beam CT

Purpose: The purpose of this study was to evaluate the changes in volume, cross-sectional area and depth of the upper airway following the surgical removal of the adenoids. Materials and Methods: 16 patients were diagnosed with hypertrophic adenoids and referred for surgical removal. Pre-surgical and post-surgical CBCT scans were taken on each patient. Volume measurements of the total airway, oropharynx and nasopharynx were recorded. In addition, cross-sectional areas and airway depths at the posterior nasal spine (PNS) and cervical vertebrae 2 were recorded. 15 patients diagnosed with no or mild adenoid hypertrophy were treated as the control group. The controls received no surgery and only a pre-surgical scan. Pre-surgical, post-surgical and control group measurements were compared for statistically significant differences. Results: Following surgery, a significant increase in total and nasopharyngeal airway volumes, cross-sectional area at PNS and airway depth at PNS was measured between the pre- and post-surgical groups. When compared with controls, the pre-surgical group demonstrated significantly smaller measurements for total and nasopharyngeal airway volume, cross-sectional area at PNS and airway depth at PNS. The post-surgical group did not exhibit any significant differences with the control group in any measurements. Conclusions: Surgical removal of adenoids results in significant changes in the total and nasopharyngeal airway volume. Significant changes also occur in cross-sectional area and airway depth at PNS

One Person, One Vote and the Constitutionality of the Winner-Take-All Allocation of Electoral College Votes

The Electoral College is an American political and constitutional curiosity. The constitutional framers believed it would produce extraordinary persons as presidents because they would be selected by men most capable of analyzing the qualities adapted to the station of the presidency.\u27 Its more recent defenders, such as Martin Diamond, have justified it as either a constitutional system meant to protect individual and minority rights or a mechanism to overcome regionalism. In Diamond\u27s view, along with the principles of separation of powers and checks and balances, it was necessary to thwart the dangers of factionalism that a popular government posed. Some have noted that, with an Electoral College, national recounts are unnecessary, as only the votes cast in disputed jurisdictions would need to be recounted
