Delayed Disaster Impacts on Academic Performance of Primary School Children

Social disruption caused by natural disasters often interrupts educational opportunities for children. However, little is known about children's learning in the following years. This study examined change in academic scores for children variably exposed to a major bushfire in Australia. Comparisons were made between children attending high, medium, and low disaster-affected primary schools 2–4 years after the disaster (n = 24,642; 9–12 years). The results showed that in reading and numeracy expected gains from Year 3 to Year 5 scores were reduced in schools with higher levels of bushfire impact. The findings highlight the extended period of academic impact and identify important opportunities for intervention in the education system to enable children to achieve their academic potential.     

Master of Professional Studies in Agriculture and Life Sciences offered through the Field of Food Science and Technology at Cornell University: A Model for the Development of a Course‐Based Graduate Degree in Food Science and Technology

The shortage of highly qualified graduates with advanced training in food science is a pressing problem facing government agencies and the food industry. This has created a need to recruit and train food scientists at the graduate level. However, most graduate level programs are research‐based and do not meet the needs of many students. The College of Agriculture and Life Sciences at Cornell Univ. has a Master of Professional Studies Program in Agriculture and Life Sciences (MPS‐ALS), which is offered through the Field of Food Science and Technology (FFST), as an alternative to research‐based masters and doctoral degrees. Although the MPS‐ALS program began in the 1970s, the FFST did not take an active role in recruiting students or tracking alumni until 2000. From 2000 to 2013, a total of 56 students, representing an internationally and academically diverse student body, have received MPS‐ALS degrees through the FFST. In May and August 2013, alumni were asked, via e‐mail, to complete an online survey to assess the long‐term impact of the MPS‐ALS program on their career success. The results of the survey indicate that the MPS‐ALS program at Cornell Univ. is a strong program that attracts excellent candidates from a variety of undergraduate fields. Program alumni have been very successful in obtaining full‐time employment, graduate positions and internships, and are highly satisfied with the program. The MPS‐ALS offered through the FFST at Cornell Univ. is a model for the development of course‐based graduate programs that seek to increase the supply of and meet the demand for trained professionals in food science.

Ice hockey skate starts: a comparison of high and low calibre skaters

The forward skating start is a fundamental skill for ice hockey players, yet extremely challenging given the low traction of the ice surface. The technique for maximum skating acceleration of the body is not well understood. The aim of this study was to evaluate kinematic ice hockey skating start movement technique in relation to a skater’s skill level. A 10-camera motion capture system placed on the ice surface recorded “hybrid-V” skate start movement patterns of high and low calibre male ice hockey players (n = 7, 8, respectively). Participants’ lower body kinematics and estimated body centre of mass (CoM) movement during the first four steps were calculated. Both skate groups had similar lower body strength profiles, yet high calibre skaters achieved greater velocity; skating technique differences most likely explained the performance differences between the groups. Unlike over ground sprint start technique, skating starts showed greater concurrent hip abduction, external rotation and extension, presumably for ideal blade-to-ice push-off orientation for propulsion. Initial analysis revealed similar hip, knee and ankle joint gross movement patterns across skaters, however, further scrutiny of the data revealed that high calibre skaters achieved greater vertical CoM acceleration during each step that in turn allowed greater horizontal traction, forward propulsion, lower double-support times and, accordingly, faster starts with higher stride rates.     

On (not) assembling a market for sustainable energy: heat network infrastructure and British cities

Energy policies increasingly rely on market instruments to meet societal objectives for climate change mitigation. We explore the application of such instruments in low carbon heat markets. Using a conceptual framework derived from actor network theory and economic sociology, we examine the role of technical-economic models as market devices in two heat network proposals in British cities. Government intermediaries relied on the models to enact the mutual financial and carbon benefits of an area-wide heat market, and to enrol multiple public sector organisations in innovation. In practice, the models produced the opposite response: parties synthesised the modelled cost–benefit calculations into the existing public services market agencement and translated the model numbers ino opportunities to secure competitive advantage for their own organisation. These activities undermined the projected cost and carbon saving logic of the collective actor solution. The findings demonstrate the potent economic agency of market-emulating public finance and competitive procurement instruments in governing such organisational decisions, and indicate the limited traction of a low carbon calculus, which lacked significant political or senior management sponsorship. Questions are posed about the formatting of economic agency suited to securing the common goods of a sustainable society.     

Parent involvement in early childhood: a comparison of English language learners and English first language families

This study evaluated parents’ communication, involvement and knowledge of their children’s abilities in reading and mathematics among parents who spoke English as a first language (EL1) and those who were English language learners (ELL). Forty‐two kindergarten‐aged children, their parents and their teachers participated in the study. Results indicated that EL1 parents communicated more frequently with the teacher than ELL parents. However, there were no language group differences in parents’ involvement in their children’s education (as rated by the teacher). For both groups of parents (EL1 and ELL), parents’ ratings of their children’s abilities in reading did not predict children’s reading scores. However, parents’ ratings of their children’s abilities in mathematics did predict their children’s mathematics scores. Further analyses indicated that this relationship was not mediated by parents’ communication or involvement. It is concluded that parents’ accurate knowledge of their children’s abilities in mathematics may be the result of their involvement at home and particularly for ELL parents, their greater understanding of and emphasis on mathematics learning.     

Performance proficiency as a measure of learning needs

Level 2 evaluation often advocates that pretest and posttest measures be collected to assess learning gains. In many military organizations, learning per se is less relevant than whether graduates can proficiently perform the job tasks for which they were hired. The critical end is performance proficiency. Incorporating methods for measuring existing performance levels as part of a Level 2 evaluation process has helped the U.S. Coast Guard prove training success.     

High school biology today: what the Committee of Ten actually said

This essay describes how in the 1890s the Committee of Ten arrived at their recommendations about the organization of the high school biological sciences and seeks to correct the frequently held, but erroneous view that the Committee of Ten was the initiator of the Biology-Chemistry-Physics order of teaching sciences prevalent in high schools today. The essay details the factors underlying the changing views of high school biology from its “natural history” origins, through its “zoology, botany, physiology” disciplinary phase to its eventual integration into a “general biology” course. The simultaneous parallel development of the “Carnegie Unit” for measuring coursework is highlighted as a significant contributor in the evolution of the present day high school biology course. The essay concludes with a discussion of the implications of the grade placement of the sciences for the future development of high school biology.
