Video for peer feedback and reflection: embedding mainstream engagement into learning and teaching practice
Lindsay Jordan
Research in Learning Technology , 2012, DOI: 10.3402/rlt.v20i0.19192
Abstract: This paper discusses the benefits and challenges of video as a tool for supporting and enhancing peer feedback and reflection. The analysis draws on key arguments from relevant literature in combination with the author's own experiences of producing and using video recordings of peer feedback sessions, presentations and personal reflections, and on learners’ experiences of the same, gathered through feedback interviews. A number of potential benefits are presented, including the exposure of additional and alternative perspectives, the assistance of focus and recall, increased impact and greater flexibility of learning. Several challenges are also explored, such as privacy of and access to recordings, participant anxiety, technical challenges and access to hardware. Strategies are offered for capitalising on the benefits while addressing the challenges. It is concluded that thoughtful use of video in the curriculum can augment the existing multiple benefits of reflection, enquiry and/or evaluation. In the specific context of teacher education, it is argued that the embedded use of technologies such as video in professional development courses can help to develop the digital literacy of teaching staff.
Transforming the student experience at a distance: Designing for collaborative online learning
Lindsay Jordan
Engineering Education , 2009,
Abstract: Distance learning programmes allow greater flexibility of learning. They are often necessary for those who wish to enhance their professional development and/or gain higher-level qualifications while simultaneously continuing to work, especially where appropriate courses of study are not offered locally. However, the isolation and lack of feedback experienced by off-campus learners are key factors in the low retention rates common to many programmes. Dependence on freelance, off-campus tutoring staff brings challenges for managing change. While there is no single solution for these problems, the student experience can be significantly improved by weaving the development of an online community into the fabric of the course of study and addressing challenges such as the relevance of curricula (including assessment and feedback procedures) through the use of appropriate technologies.This article describes the redevelopment of a series of distance learning modules through the application of established educational principles. It explains the need for and approach to change and documents how learning technologies have been applied to combat student and tutor isolation, improve the quality, quantity and variety of feedback sources and increase student engagement with feedback.The lessons learned throughout this redevelopment project will be of interest for educators developing or redeveloping online blended or distance learning programmes, particularly in Engineering and/or Built Environment subject areas.
Chinese Dragons and Indigenous Tricksters: Lessons for Leadership through an Intersection of People, Culture, Thought, and Practice  [PDF]
William G. Lindsay
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.96067
Abstract: During the course of recent research, this author has discovered similarities between aspects of classical Chinese philosophies and practices of those of traditional Canadian First Nations (Indigenous) peoples. Included in this has been a discovery that aspects of traditional leadership skills from both cultures intersect and are applicable to the work happening in a modern Canadian university. The author has also personally observed an overlap in the culture and lives of Chinese and First Nations people in modern British Columbia, continuing a 150-year tradition in this part of Canada. This paper—tying aspects of these two cultural and historic threads together—will consider the questions: What fascinating observations can be made and what personal, philosophical, and leadership lessons can be contrasted and compared, learned and shared through this historic intersection of peoples, cultures, thoughts, and practices? And can these over-lapping examples assist in solving larger problems of identity in the modern world?

Sensors , 2005, DOI: 10.3390/s5010051
Abstract: Groundwater contamination from 90Sr is an environmental challenge posed topresent and former nuclear weapons related sites. Traditional methods of extractinggroundwater samples and performing laboratory analyses are expensive, time-consumingand induce significant disposal challenges. The authors present here a prototype countercapable of measuring 90Sr groundwater concentrations in-situ at or below the drinking waterlimit of 8 pCi/liter. The 90Y daughter of 90Sr produces high-energy electrons, which cancreate Cerenkov light. Photomultiplier tubes convert the Cerenkov light into an electronicpulse, which then undergoes signal processing with standard electronics. Strontium-90concentrations near the drinking water limit can be measured in a matter of hours if it is insecular equilibrium with the 90Y daughter. The prototype counter is compact, can bedeployed in an American Standard 6-inch, well while operated by a single person, andtransmits the results to a central monitoring location.
Experimental Investigation of Spoiler Deployment on Wing Stall  [PDF]
Scott Douglas Lindsay, Paul Walsh
Open Journal of Fluid Dynamics (OJFD) , 2018, DOI: 10.4236/ojfd.2018.83019
Abstract: Upper surface wing flaps, known as spoiler, are typically used to reduce lift and increase drag at touchdown; however spoilers have been shown to increase lift and reduce drag at near-stall conditions. The purpose of this experiment was to determine the spoilers’ impact on lift, drag, moment, and aerodynamic efficiency of a NACA 2412 airfoil at angles of attack (α) from 8 ° to 32 °. The experiment was conducted in the Ryerson Low-Speed Wind Tunnel (closed-circuit, 1 m × 1 m test section) at Re=783761, Ma=0.136. The lift coefficient (Cl), drag coefficient (Cd), moment coefficient about the quarter-chord (\"\") were captured with a changing spoiler deflection angle (δ) and spoiler length (b in percent chord). It was found that deflecting the spoiler resulted in an increase maximum lift of up to 2.497%. It was found that deflecting the spoiler by 8° was optimal for the b=10 cases. Any larger deflection reduced the lift gain, and a deflection of 25° caused the maximum lift to be 2.786% less than the clean configuration. In the b=15 case, δ=15° was optimal (1.760% maximum lift coefficient increase). The b=10 cases increased maximum lift coefficient between 0.35% and 2.10% higher than the b=15
Further Properties of Reproducing Graphs  [PDF]
Jonathan Jordan, Richard Southwell
Applied Mathematics (AM) , 2010, DOI: 10.4236/am.2010.15045
Abstract: Many real world networks grow because their elements get replicated. Previously Southwell and Cannings introduced a class of models within which networks change because the vertices within them reproduce. This happens deterministically so each vertex simultaneously produces an offspring every update. These offspring could represent individuals, companies, proteins or websites. The connections given to these offspring depend upon their parent’s connectivity much as a child is likely to interact with their parent’s friends or a new website may copy the links of pre-existing one. In this paper we further investigate one particular model, ‘model 3’, where offspring connect to their parent and parent’s neighbours. This model has some particularly interesting features, including a degree distribution with an interesting fractal-like form, and was introduced independently under the name Iterated Local Transitivity by Bonato et al. In particular we show connections between this degree distribution and the theory of integer partitions and show that this can be used to explain some of the features of the degree distribution; we give exact formulae for the number of complete subgraphs and the global clustering coefficient and we show how to calculate the minimal cycle basis.
A Comparative Analysis of MMPI and Rorschach Findings Assessing Combat-Related PTSD in Vietnam Veterans—Analysis of MMPI and Rorschach Findings Assessing PTSD  [PDF]
Ioanna Katsounari, Jordan Jacobowitz
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.24053
Abstract: There has been a proliferation of assessment research on Post-traumatic Stress Disorder (PTSD) over the past twenty years. In spite of recent advances in the PTSD assessment research, there continues to be a controversy as to whether the MMPI or Rorschach is more useful in determining the presence of PTSD. The present comparative analysis of the research literature will carefully evaluate controlled empirical studies, which utilized psychometric measures such as the MMPI/2 and Rorschach to identify PTSD in Vietnam Veterans. This analysis is guided by the paucity of comparative data for standardized objective and projective instruments to assess combat-related PTSD. The analysis indicated that the MMPI as an assessment instrument focuses on symptom recognition of PTSD while the Rorschach seems to be more likely to identify chronic adaptations to trauma. The significance of pre-combat factors, such as preexisting personality, and their impact on the way individuals make meaning and express traumatic experiences needs to be further addressed in future research. The need for reliable and valid measures to assess combat-related PTSD is urgent as an increasing number of soldiers return from war zones.
Maximizing Sampling Efficiency  [PDF]
Harmon S. Jordan
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.411209
Abstract: Background and Goals: Although health care quality improvement has traditionally involved extensive work with paper records, the adoption of health information technology has increased the use of electronic record and administrative systems. Despite these advances, quality improvement practitioners now and for the foreseeable future need guidance in defining populations of individuals for study and in selecting and analyzing sample data from such populations. Statistical data analysis in health care research often involves using samples to make inferences about populations. The investigator needs to consider the goals of the study, whether sampling is to be used, and the type of population being studied. While there are numerous sampling strategies designed to conserve resources and yield accurate results, one of these techniques—use of the finite population correction (FPC)—has received relatively little attention in health care sampling contexts. It is important for health care quality practitioners to be aware of sampling options that may increase accuracy and conserve resources. This article describes common sampling situations in which the issue of the finite population correction decision often arises. Methods: This article describes 3 relevant sampling situations that influence the design and analysis phases of a study and offers guidance for choosing the most effective and efficient design. Situation 1: The study or activity involves taking a sample from a large finite target population for which enumerative inferences are needed. Situation 2: The population is finite and the study is enumerative. A complete enumerative count of “defects” in the process is needed so that remediation can occur. Here, statistical inference is unnecessary. Situation 3: The target population is viewed as infinite; such populations are “conceptual populations” [1] or “processes”. Results: The article shows how savings in resources can be achieved by choosing the correct analytic framework at the conceptualization phase of study design. Choosing the right sampling approach can produce accurate results at lower costs. Several examples are presented and the implications for health services research are discussed. Conclusion: By clearly specifying the objectives of a
Correlated Individual Differences and Choice Prediction
Luke Lindsay
Games , 2011, DOI: 10.3390/g2010016
Abstract: This note briefly summarizes the consequences of adding correlated individual differences to the best baseline model in the Games competition, I-SAW. I find evidence that the traits of an individual are correlated, but refining I-SAW to capture these correlations does not significantly improve the model’s accuracy when predicting average behavior.

Revista Brasileira de História das Religi?es , 2012,
Abstract: Nesse artigo s o examinados discursos do primeiro arcebispo de Goiania, Dom Fernando Gomes dos Santos, publicados na Revista da Arquidiocese, nos quais projetava Goiás como modelo de regi o que se desenvolvia sob o influxo da Igreja. Por meio de uma contextualiza o histórica, o objetivo é perscrutar como as propostas do prelado se inseriram no projeto desenvolvimentista preconizado para o Brasil. O propósito é sinalizar, ainda, como o prelado interpretou os conceitos de civiliza o e cultura muito em voga no período e que foram por ele traduzidos sob a perspectiva da Igreja. Em uma sociedade em acelerado processo de moderniza o, nos anos 1950, a Igreja se engajou nas discuss es e nos projetos de desenvolvimento do país, como forma de manter a hegemonia religiosa. Para o arcebispo, Goiás deveria ser inserido de modo particular nesse processo, pela sua localiza o geográfica e pela funda o de sua capital, Goiania (1933), e de Brasília (1960), signos de seu papel progressista.
