Optimum plant density for crowding stress tolerant processing sweet corn in the Upper Midwest
No full textAdvances in grain yield of field corn (Zea mays L.) over the last quarter century have been driven in large part by the ability of modern hybrids to better tolerate higher plant densities (i.e., crowding stress) than their predecessors. Yield gains in processing sweet corn, however, pale in comparison to field corn. Recent studies have identified modern sweet corn hybrids with crowding stress tolerance (CST); however, such hybrids appear to be under-planted in the Upper Midwest – where most of the world’s processing sweet corn is grown. Both contract growers and vegetable processors may realize improved sustainability by growing CST hybrids at optimum plant densities. In collaboration with vegetable processors and their contract growers, on-farm experiments with CST hybrids were conducted to: (1) identify optimum plant densities of CST hybrids under actual conditions in which the crop is grown and, (2) to determine the best approach to making recommendations on plant densities for individual fields in the Upper Midwest.
Optimum plant densities for CST processing sweet corn hybrid ranged from 65,900 to 79,500 plants ha-1 in the Upper Midwest. Also, optimum plant densities increased average profitability of both the processor and contract grower without compromising ear traits important to the sweet corn processing industry. Six candidate recommendation domains were compared to identify the best approach for making plant density recommendations for individual fields. This study identified the ‘Production Area’ recommendation domain model (RDMPA) as the most appropriate for setting target plant densities for CST sweet corn. Fortuitously, the vegetable crop industry organizes field management decisions largely along the lines of the RDMPA model; therefore, production area-specific plant densities recommendations have a familiar appeal to the practitioner. Vegetable processors and their contract growers stand to increase sweet corn profitability up to 82 ha-1, respectively, by fully utilizing the genetic potential of CST hybrids in the Upper Midwest. This research reveals a relatively simple approach to improve a yield trend in processing sweet corn which has been largely stagnant for two decades.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-05-01The student, Daljeet Dhaliwal, accepted the attached license on 2018-04-25 at 12:31.The student, Daljeet Dhaliwal, submitted this Thesis for approval on 2018-04-25 at 12:47.This Thesis was approved for publication on 2018-04-26 at 08:20.DSpace SAF Submission Ingestion Package generated from Vireo submission #12482 on 2018-08-31 at 17:21:31Made available in DSpace on 2018-09-04T20:36:54Z (GMT).

An observational study of the proceedings of the All India Ophthalmological Conference, 2000 and subsequent publication in indexed journals
No full textAims: To determine the quality of reporting in the proceedings of the All India Ophthalmological Conference (AIOC) 2000, subsequent rate of publication in an indexed journal and differences between the proceedings and the journal version of these papers. Design: Observational study. Materials and Methods: All papers presented at the AIOC 2000 were retrieved from the proceedings and assessed for completeness of reporting. To determine the subsequent full publication, a Medline search was performed as of January 2007; consistency between the proceedings paper and the final publication was evaluated. Statistical analysis: Chi square and Fisher′s exact tests were used to compare publication rates based on geographical location, subspecialty and study design; Student′s t -test was used to compare differences based on the number of authors and sample size. Results: Two hundred papers were retrieved; many failed to include study dates, design or statistical methods employed. Thirty-three (16.5%) papers were subsequently published in indexed journals by January 2007. The published version differed from the proceedings paper in 27 (81.8%) instances, mostly relating to changes in author name, number or sequence. Conclusions: The overall quality of reporting of scientific papers in the proceedings of the AIOC 2000 was inadequate and many did not result in publication in an indexed journal. Differences between the published paper in journals and in proceedings were seen in several instances. Ophthalmologists should be cautious about using the information provided in conference proceedings in their ophthalmic practice
The effects of footwear on isometric squat force
No full textWhen you google, squatting barefoot‚ you will find many websites claiming that squatting barefoot or in socks increases your mobility and squat max. The explanation for squatting barefoot is that famous bodybuilders like Arnold Schwarzenegger and Lou Ferrigno used to do it, so it must be better than squatting with shoes. Even some fitness influencers tell their followers to either squat with no shoes or certain shoes and claim all types of benefits without any scientific backing.
As researchers, we wondered if there was a significant difference in force production while performing an isometric front squat in an athlete's self-selected shoes vs in their socks.
This study will be conducted by participants recruited via convenient sampling. The participants will represent 12-16 healthy Douglas College students of any age or gender. These participants will be students in the BPEC program that have experience with squatting. Their training history does not have to be extensive, as long as they go to the gym and do not have any major health complications, they are eligible for this study. This study will be conducted in a quantitative, quasi-experimental design. Each participant will be asked to come to one of the labs in Douglas College and will be asked to bring with them the pair of shoes that they most commonly wear while working out at the gym.
The majority of findings show that barefoot squatting has little benefit. However, most research is focused on the deadl lift instead of the front squat.
Our hypothesis is that there will be slightly higher force production when barefoot compared to when wearing shoes.

The effects of high tempo and slow tempo music on reaction time
No full textOur study aims to determine if slow tempo or high tempo music has an effect on one’s reaction time. Reaction time is an important skill in day to day activities such as driving, playing sports, or even in school. The objective of this study was to determine differences in reaction time scores between slow tempo music, high tempo music and no music. The purpose is to determine which is the most beneficial for improving reaction time skills. It was identified in the study that students displayed quicker reaction times when listening to low tempo music. However, it was also discovered that students demonstrated better accuracy when listening to high tempo music. We hypothesized that this may have occurred because with the second group high tempo music was done after low tempo music which means students had time to get used to the test after the low tempo trial. For future studies who have more time it would be beneficial to test music trials on separate days to avoid the chance of participants becoming familiar with the test. As well it would be beneficial for future studies to test how listening to low and high tempo music before the test can affect reaction time. This poster was presented at the Douglas College Student Research Day 2022 on April 15, 2022.Not peer reviewedStudent Research Day Poster (2022

No full textBackground: The thesis is an integral part of postgraduate medical education in India. Publication of the results of the thesis in an indexed journal is desirable; it validates the research and makes results available to researchers worldwide. Aims: To determine publication rates in indexed journals, of works derived from theses, and factors affecting publication. Settings and Design: Postgraduate theses submitted over a five-year period (2001-05) in a university medical college were analyzed in a retrospective, observational study. Materials and Methods: Data retrieved included name and gender of postgraduate student, names, department and hierarchy of supervisor and co-supervisor(s), year submitted, study design, sample size, and statistically significant difference between groups. To determine subsequent publication in an indexed journal, Medline search was performed up to December 2007. Statistical Analysis: Chi square test was used to compare publication rates based on categorical variables; Student′s t-test was used to compare differences based on continuous variables. Results: One hundred and sixty theses were retrieved, forty-eight (30%) were published. Papers were published 8-74 (33.7 ± 17.33) months after thesis submission; the postgraduate student was first author in papers from 26 (54%) of the published theses. Gender of the student, department of origin, year of thesis submission, hierarchy of the supervisor, number and department of co-supervisors, and thesis characteristics did not influence publication rates. Conclusions: Rate of publication in indexed journals, of papers derived from postgraduate theses is 30%. In this study we were unable to identify factors that promote publication

Research in Accounting for Income Taxes
No full textThis paper comprehensively reviews Accounting for Income Taxes (AFIT). The first half provides background and a primer on AFIT. The second half reviews existing studies in detail and offers suggestions for future research. We emphasize the research questions that have been addressed (most of which relate to whether the tax accounts are used to manage earnings, and whether the tax accounts are priced by equity market participants) and highlight areas that have not received much research attention. We close with a call for a theoretical framework, more study of the inconsistencies between research and practice, and improved econometrics.
