COTTON LAND TENURE EVALUATION SOFTWARE USERS' GUIDE

The Federal Agriculture Improvement and Reform Act of 1996 (FAIR Act) introduces several significant changes to farm commodity legislation. While these changes impact all program commodities, they have prompted considerable concern for the future of the Texas cotton industry. Changes in the farm program have prompted many landowners and tenants to evaluate their current rental arrangements and determine if changes are required. In response to considerable ensuing questions regarding the land rental market, a Lotus 1-2-3 template was developed to aid parties in determining an equitable lease. This Lotus template allows users to specify enterprise budget information for rice farm operations and then evaluates the expected returns to producers and landowners under various lease scenarios. The landowners' results are compared with the returns from 100% of the market transition payments and user-specified net returns for an alternative enterprise to calculate the net advantage to landowners for producing rice under the budgeted scenario over the life of the FAIR Act. The Cotton Land Tenure Evaluation Users' Guide is a detailed explanation of how to use the Lotus Cotton Land Tenure Evaluation program. This guide instructs users on how to use the various components of the program. Sections of the Users' Guide include a preface, installation instructions, an overview of the changes in the farm program, a section describing how to input data, a description of the custom menu system, and a report section that illustrates examples of the reports that are available for printing.Agricultural and Food Policy,

GRAIN LAND TENURE EVALUATION SOFTWARE USERS' GUIDE

The Federal Agriculture Improvement and Reform Act of 1996 (FAIR Act) introduces several significant changes to farm commodity legislation. While these changes impact all program commodities, they have prompted considerable concern for the future of the Texas grain industry. Changes in the farm program have prompted many landowners and tenants to evaluate their current rental arrangements and determine if changes are required. In response to considerable ensuing questions regarding the land rental market, a Lotus 1-2-3 template was developed to aid parties in determining an equitable lease. This Lotus template allows users to specify enterprise budget information for grain farm operations and then evaluates the expected returns to producers and landowners under various lease scenarios. The landowners' results are compared with the returns from 100% of the market transition payments and user-specified net returns for an alternative enterprise to calculate the net advantage to landowners for producing grain under the budgeted scenario over the life of the FAIR Act. The Grain Land Tenure Evaluation Users' Guide is a detailed explanation of how to use the Lotus Grain Land Tenure Evaluation program.

A section in the Users' Guide explains how to switch from one crop to another.Agricultural and Food Policy,

Short vs. long: cognitive load, retention and changing class structures

University class structure is changing. To accommodate working students, programmes are increasing their offerings of long night classes – some lasting as long as six hours. While these long classes may be more convenient for students, they have unintended consequences as a result of cognitive load. Using a panel of 124 students (372 observations) and a differencing approach that controls for student characteristics, we show that student exam performance decreases by approximately one-half letter grade on content taught in the second half of a long class (significant at the 5% level)

Comparison of a Continuous and Discontinuous GXT on VO2 in Resistance-Trained and Endurance-Trained Males

International Journal of Exercise Science 15(4): 414-422, 2022. Traditional graded exercise testing to assess maximal oxygen uptake (VO2max) may not well represent resistance-trained athletes due to their unfamiliarity with continuous exercise. For this reason, it is possible discontinuous exercise protocols may better represent the maximum capacity for aerobic metabolism in resistance-trained athletes, in order to provide a more valid assessment of VO2max and risk of developing cardiovascular disease. Purpose: The purpose of this experiment was to compare VO2peak during a continuous and discontinuous modified Bruce protocol in both highly resistance-trained and endurance-trained males. Methods: 19 college-aged males (age: 20.6 ± 1.9 yr, height: 176.5 ± 7.6 cm, weight: 85.0 ± 25.6 kg) of intermediate resistance- or endurance-trained status were recruited for this study. Participants completed a continuous and discontinuous modified Bruce protocol on two visits separated by seven days. Results: A 2x2 one-way ANOVA revealed a significant group main effect for VO2peak (p = 0.004) in which endurance athletes achieved significantly higher VO2peak values compared to resistance-trained athletes. A significant group main effect for RPE was found (p = 0.045) in which endurance-trained reported significantly higher RPE values than the resistance-trained. A significant main effect for protocol for heart rate (p = 0.033) was found in which individuals achieved higher heart rates during the continuous protocol compared to the discontinuous. Conclusion: Although a discontinuous protocol with rest periods between stages is comparable to the exercise mode familiar to resistance-trained athletes, it did not provide any additional benefit to VO2peak values

Dissipative dispersion-managed solitons in mode-locked lasers

We extend the theory of dispersion-managed solitons to dissipative systems with a focus on mode-locked fiber lasers. Dissipative structures exist at high map strengths, leading to the generation of stable, short pulses with high energy. Two types of intramap pulse evolution are observed depending on the net cavity dispersion. These are characterized by a reduced model, and semianalytical solutions are obtained

Improving Neurosurgery Education Using Social Media Case-Based Discussions: A Pilot Study.

BACKGROUND: The increasing shift toward a more generalized medical undergraduate curriculum has led to limited exposure to subspecialties, including neurosurgery. The lack of standardized teaching may result in insufficient coverage of core learning outcomes. Social media (SoMe) in medical education are becoming an increasingly accepted and popular way for students to meet learning objectives outside formal medical school teaching. We delivered a series of case-based discussions (CbDs) over SoMe to attempt to meet core learning needs in neurosurgery and determine whether SoMe-based CbDs were an acceptable method of education. METHODS: Twitter was used as a medium to host 9 CbDs pertaining to common neurosurgical conditions in practice. A sequence of informative and interactive tweets were formulated before live CbDs and tweeted in progressive order. Demographic data and participant feedback were collected. RESULTS: A total of 277 participants were recorded across 9 CbDs, with 654,584 impressions generated. Feedback responses were received from 135 participants (48.7%). Participants indicated an increase of 77% in their level of knowledge after participating. Of participants, 57% (n = 77) had previous CbD experience as part of traditional medical education, with 62% (n = 84) receiving a form of medical education previously through SoMe. All participants believed that the CbDs objectives were met and would attend future sessions. Of participants, 99% (n = 134) indicated that their expectations were met. CONCLUSIONS: SoMe has been shown to be a favorable and feasible medium to host live, text-based interactive CbDs. SoMe is a useful tool for teaching undergraduate neurosurgery and is easily translatable to all domains of medicine and surgery

Transonic Elastic Model for Wiggly Goto-Nambu String

The hitherto controversial proposition that a ``wiggly" Goto-Nambu cosmic string can be effectively represented by an elastic string model of exactly transonic type (with energy density $U$ inversely proportional to its tension $T$) is shown to have a firm mathematical basis.Comment: 8 pages, plain TeX, no figure

Neurosurgeons’ experiences of conducting and disseminating clinical research in low- and middle-income countries: a qualitative study protocol

Low-income and middle-income countries (LMICs) face the greatest burden of neurotrauma. However, most of the research published in scientific journals originates from high-income countries, suggesting those in LMICs are either not engaging in research or are not publishing it. Evidence originating in high-income countries may not be generalisable to LMICs; therefore, it is important to nurture research capacity in LMICs so that a relevant evidence base can be developed. However, little is published about specific challenges or contextual issues relevant to increasing research activity of neurosurgeons in LMICs. Therefore, the aim of this study was to understand neurosurgeons’ experiences of, aspirations for and ability to conduct and disseminate clinical research in LMICs.Methods and analysisThis is a pragmatic qualitative study situated within the naturalistic paradigm using focus groups and interviews with a purposive sample of neurosurgeons from LMICs. First, we will conduct asynchronous online focus groups with 36 neurosurgeons to broadly explore issues relevant to the study aim. Second, we will select 20 participants for follow-up semistructured interviews to explore concepts in more depth and detail than could be achieved in the focus group. Interviews will be audio-recorded and transcribed verbatim. A thematic analysis will be conducted following Braun and Clarke’s six stages and will be supported by NVIVO software.Ethics and disseminationThe University of Cambridge Psychology Research Ethics Committee reviewed this study and provided a favourable opinion in January 2020 (REF PRE.2020.006). Participants will provide informed consent, be able to withdraw at any time and will have their contributions kept confidential. The findings of the study will be shared with relevant stakeholders and disseminated in conference presentations and journal publications.</jats:sec

‘Perceptions of non-accidental child deaths as preventable events: The impact of probability heuristics and biases on child protection work'

Anxiety about the possibility of non-accidental deaths of children has had a major influence on child care policy and practice over the last 40 years. The formal inquiry reports and media coverage of these rare events serve to maintain the perception that these are regular incidents that happen far too often and that they could have been prevented. This focus on individual events tends to distort a clear view of the actual probability of non-accidental deaths and serves to reinforce the notion that potentially all child care cases are risky and that any social work practitioner could be involved in such a case. As a result, work with children has become highly risk averse. However, in statistical terms, the probability of non-accidental child deaths is very low and recently has averaged about 55 deaths a year. Children are at considerably higher risk of being killed on the roads. This paper examines the way in which perceptions of the ‘high’ level of risk of possible child deaths are maintained despite the very low statistical probability of such incidents. It draws on thinking from behavioural psychology and, in particular the work of Kahneman and Tversky, to consider some of the biases in probability reasoning affecting people’s perception of risk and explores how inquiry reports into single past events reconfirm risk perceptions. It is suggested that recognition of the essentially unpredictable nature of future non-accidental child deaths would free up childcare professionals to work in a more positive and less risk-averse manner in the present
