Memories and Reflections on the Dieppe Raid of 19 August 1942

Editor’s Note: John S. Edmondson was born in Estevan, Saskatchewan in 1919. He joined the Princess Patricia’s Canadian Light Infantry in 1938, and then served with the South Saskatchewan Regiment during the Second World War in the Defence of England, on the Dieppe Raid and in the Normandy Campaign until wounded during the capture of Falaise. After the war, he was transferred to the Black Watch (RHR) Regiment of Canada. He served in Canada in many roles, and as an exchange officer with the British 4th Division in West Germany as part of NATO. In addition, he served with the UN Military Observer Group in Kashmir, India and Pakistan. He served until reaching the mandatory retirement age in 1971. John, with the assistance of his son Doug, wrote this account of his experiences at Pourville in 1993, revising it in 2003

Past developments and future opportunities in the design and analysis of crop experiments

A review of papers on the statistical design and analysis of experiments published in the Journal of Agricultural Science, Cambridge, over the last 100 years is presented. The development of significant ideas in the practical design of field experiments is reviewed. Some possible future developments in the design of spatial field trials and computer-aided design of experiments are discussed

Image analysis and statistical modelling for measurement and quality assessment of ornamental horticulture crops in glasshouses

Image analysis for ornamental crops is discussed with examples from the bedding plant industry. Feed-forward artificial neural networks are used to segment top and side view images of three contrasting species of bedding plants. The segmented images provide objective measurements of leaf and flower cover, colour, uniformity and leaf canopy height. On each imaging occasion, each pack was scored for quality by an assessor panel and it is shown that image analysis can explain 88.5%, 81.7% and 70.4% of the panel quality scores for the three species, respectively. Stereoscopy for crop height and uniformity is outlined briefly. The methods discussed here could be used for crop grading at marketing or for monitoring and assessment of growing crops within a glasshouse during all stages of production

Climate change : a response surface study of the effects of CO2 and temperature on the growth of French beans

The possible impact of global rises in atmospheric CO2 concentration and temperature on the growth and development of French beans (Phaseolus vulgaris) was examined using growth cabinets. Five CO2 concentrations of 350, 450, 550, 650 and 750 vpm and five temperatures of 14·5, 15·5, 16·5, 17·5 and 18·5°C were tested using a fractional factorial design comprising nine treatment combinations of the two factors. Plants were grown under constant irradiance, common atmospheric humidities (vpd 0·5 kPa) and non-limiting supplies of water and mineral nutrients. The plant growth response was modelled by fitting polynomial response function curves to the times to first flower opening, first bean set, 50% maturity and the number and yield of beans. The effects of temperature were large and positive for most of the measured variables, whereas the effects of CO2 were small and negative or non-existent. Increased temperature substantially reduced the time to flowering and the time from bean set to 50% maturity and increased the number and yield of mature beans whereas increased CO2 concentration had little effect on plant growth except that bean yield was very slightly reduced. There was no significant evidence of interaction between the CO2 concentration effects and the temperature effects. The time to maturity and yield of mature beans was simulated for the 2020s (2010 to 2039) and the 2050s (2040 to 2069) using the fitted polynomial models and four climate change scenarios suggested by the UK Climate Impacts Programme. These simulations showed that, depending upon the assumed scenario, the 2020s yields could rise by 39–84% and time to maturity reduce by between 6 and 15 days whereas the 2050s yields could rise by 51–118% and time to maturity reduce by between 9 and 25 days

Evaluating the Effectiveness of a Telepresence-Enabled Cognitive Apprenticeship Model of Teacher Professional Development

This exploratory research used a mixed-methods design to compare the effectiveness of a telepresence-enabled cognitive apprenticeship model of teacher professional development (TEAM-PD) to that of a traditional workshop model by examining outcomes in teacher pedagogy and student achievement. Measures of the lll degree to which teachers in both groups enacted mathematics pedagogy provided mixed results. Both groups demonstrated similar patterns of behavior and cognition, indicating modest levels of pedagogy implementation. Although the experimental group demonstrated higher levels of enactment of the mathematics pedagogy, the comparison group demonstrated a faster rate of growth. Student outcome data were clear: students of teachers in the experimental group scored substantially higher on a test of relevant mathematics content than students of teachers in the comparison group. Collectively the results suggest that TEAM-PD has potential to be an effective model of teacher professional development

Science Leadership: Impact of the New Science Coordinators Academy

This article discusses the impact of the New Science Coordinators Academy (NSCA) on two cohorts of participants. The NSCA is one of four components of the Virginia Initiative for Science Teaching and Achievement (VISTA), a United States Department of Education (USED) science education reform grant. The NSCA is designed to support new school district science coordinators (with less than five years of experience) and to continue building the state science education infrastructure. Research in education leadership traditionally focuses on teacher leaders, principals, and district office personnel. Interestingly, research on district office personnel rarely distinguishes between the different roles of district personnel. This article seeks to inform the field by sharing the impact of an academy designed for new science coordinators on their learning, and to begin to understand their role and impact in their district. The five-day Academy engaged participants in a variety of experiences designed to facilitate the following: 1) build leadership skills; 2) build a common understanding and vision for hands-on science, inquiry, problem-based learning, and nature of science in the science classroom; 3) investigate data to improve student learning goals; 4) and, develop a science strategic plan. The data indicate that the NSCA was successful at meeting its goals to support the participants and to build a common language among these new coordinators. Initial data also support the variety of responsibilities of these participants and the positive impact of the Academy on their district work

Identifying the Bases for Gender Differences in Guilt and Shame

Gender differences are frequently revealed on the popular TOSCA-2 measure of guilt- and shame-proneness. These gender differences could reflect biases in the eliciting conditions that participants evaluate and confounds between them. A new instrument, the Gender Relevant Test of Self-Conscious Affect (GR-TOSCA), was developed to eliminate these confounds, thereby introducing a gender-sensitive, and therefore more valid, measure of guilt and shame proneness. The psychometric integrity of the new instrument, hypotheses regarding condition-specific gender differences in the two emotions, and relationships of guilt- and shame-proneness scores to gender role endorsement were examined in a sample of undergraduate students (93 men and 109 women). Encouraging evidence was produced for the reliability and validity of the GR-TOSCA, but the hypothesized gender differences in guilt and shame proneness were not found. Several possibilities for these results are explored, including the possibility of biases in the research procedure

Students\u27 Attitudes towards Textbook Types: Are Students Really Ready for E-Textbooks?

Abstract - This study examines students’ attitudes and preferences to the four primary textbook types currently on the market. These types include hardback, paperback, loose leaf, and E-textbook. Two hundred twenty-three students currently taking Principles of Marketing from a large public university in the southeastern United States completed the survey. Results found that students still prefer paperback textbooks, even when this textbook is at a higher price than other alternatives. When students were asked their opinions on the various textbook options, it was clear that price, ease of use, health concerns, and ownership desires were the primary reasons why they liked and/or disliked the various textbook options

A Sad Clown Story: McDonald\u27s Lack of Support for Ronald McDonald Houses

Ronald McDonald House Charities (RMHC) was created in 1974 to “provide housing for the families of sick children and for children receiving outpatient care” (“McDonald’s gives little,” 2013). RMHC currently has locations in more than 60 countries and regions around the world (“Ronald,” 2015). Each Ronald McDonald House establishes their own policies, budget, and fundraising goals; therefore, assets from each house are not co-mingled (Morran, 2013). Considering RMHC is named after Ronald McDonald from the McDonald’s Corporation, one would expect that McDonald’s makes extensive financial contributions to RMHC; however, this is not the case. The company has recently come under fire because RMHC only gets about 10% of their money from McDonald’s (Morran 2013). Further complicating matters is the fact that most of this 10% contribution actually comes from McDonald’s consumers via donation boxes at supporting McDonald’s restaurants. McDonald’s contributes only one penny to RMHC for each Happy Meal or Mighty Kids Meal purchased. (“McDonalds,” 2015). Overall, McDonald’s philanthropic contributions are 33% lower than other leading corporations (Kim, 2013)
