An introduction to learning management systems

This paper outlines the fundamental factors that emerge when determining whether a LMS would be an advantage in any given educational environment. Administrators, computer co-ordinators and even classroom teachers are being asked to help determine whether their institution should invest in a Learning Management System. Many know little about the area, their technical skills vary widely and most are unable to tell sales people what they want, let alone negotiate their way through to the best deal. This paper provides a balanced overview of what learning environments can expect from a learning management system.
The Use of ProteoTuner Technology to Study Nuclear Factor κB Activation by Heavy Ions

Nuclear factor κB (NF-κB) activation might be central to heavy ion-induced detrimental processes such as cancer promotion and progression and sustained inflammatory responses. A sensitive detection system is crucial to better understand its involvement in these processes. Therefore, a DD-tdTomato fluorescent protein-based reporter system was previously constructed with human embryonic kidney (HEK) cells expressing DD-tdTomato as a reporter under the control of a promoter containing NF-κB binding sites (HEK-pNFκB-DD-tdTomato-C8). Using this reporter cell line, NF-κB activation after exposure to different energetic heavy ions (16O, 95 MeV/n, linear energy transfer—LET 51 keV/µm; 12C, 95 MeV/n, LET 73 keV/μm; 36Ar, 95 MeV/n, LET 272 keV/µm) was quantified considering the dose and number of heavy ions hits per cell nucleus that double NF-κB-dependent DD-tdTomato expression. Approximately 44 hits of 16O ions and ≈45 hits of 12C ions per cell nucleus were required to double the NF-κB-dependent DD-tdTomato expression, whereas only ≈3 hits of 36Ar ions were sufficient. In the presence of Shield-1, a synthetic molecule that stabilizes DD-tdTomato, even a single particle hit of 36Ar ions doubled NF-κB-dependent DD-tdTomato expression. In conclusion, stabilization of the reporter protein can increase the sensitivity for NF-κB activation detection by a factor of three, allowing the detection of single particle hits’ effects.
Equilibrium reinsurance-investment strategy with a common shock under two kinds of premium principles

This paper investigates the optimal mean-variance reinsurance-investment problem for an insurer with a common shock dependence under two kinds of popular premium principles: the variance premium principle and the expected value premium principle. We formulate the optimization problem within a game theoretic framework and derive the closed-form expressions of the equilibrium reinsurance-investment strategy and equilibrium value function under the two different premium principles by solving the extended Hamilton-Jacobi-Bellman system of equations. We find that under the variance premium principle, the proportional reinsurance is the optimal reinsurance strategy for the optimal reinsurance-investment problem with a common shock, while under the expected value premium principle, the excess-of-loss reinsurance is the optimal reinsurance strategy. In addition, we illustrate the equilibrium reinsurance-investment strategy by numerical examples and discuss the impacts of model parameters on the equilibrium strategy.
Indications of Goal Displacement in Regulatory Enforcement Agencies: An Empirical Exploration

This paper describes indications of goal displacement in regulatory enforcement agencies as reported by enforcement professionals from a range of regulatory domains. The findings suggest that the occurrence of this phenomenon in these agencies may be more prevalent and multifaceted than expected. Among the goal-displacement types reported as most impactful were goal narrowing, induced by calamities, goal diversion through ongoing organizational reform, and goal diversion brought upon by strict regimes of output management. A systematic exploration of these various goal-displacement types as conducted here sheds light onto the intricate nature of goal alignment of these agencies.
Speed of a Bipolar CE Amplifier Stage

Expressions relating the bandwidth of a common- emitter (CE) amplifier stage and the small-signal CML gate delay time to directly measurable transistor parameters, such as , , and input bandwidth , are presented. They are valid for an arbitrary division of the base resistance and base-collector depletion capacitance into internal and external components. No resistance measurements are needed. It is shown that the transistor input bandwidth is an important figure of merit for the speed of a CE stage. Under a given bias condition, is determined by the base resistance and the cut-off frequency. In most cases the value of the maximum oscillation frequency is only of minor importance. It would therefore be more meaningful to present besides also instead of as a figure of merit for transistors for high-speed, low-power analog and digital circuits. NOMENCLATURE Internal base-collector capacitance. External base-collector capacitances.
Immune-Mediated Renal Diseases: A Team-Based Learning Module for Preclinical Medical Students

Introduction The underlying immune mechanisms of renal diseases are complex, and medical students benefit from learning these complexities in the setting of team-based learning (TBL), where they can apply foundational immunologic concepts to clinical problems. Methods This immune-mediated renal disease TBL module focusing on glomerular disease was delivered over a period of 2 consecutive years in an integrated cardiovascular, pulmonary, and renal block within the second semester of the first year of medical school. Each class consisted of 53 students, for a total of 106 students. The TBL module consisted of a seven-question individual and team readiness assurance test (iRAT and tRAT) and two clinically relevant team application activities. Following the TBL module, students completed an 18-item survey that collected information on student perspectives of engagement. Results For the 2-year period, the iRAT average scores were 73% and 74%, and the tRAT average scores were 100% and 99%, respectively. The survey assessing student perceptions of engagement yielded positive feedback. Discussion In summary, this TBL module effectively integrates the foundational and clinical sciences to teach higher-order concepts in immunology and renal disease pathogenesis to medical students.
Reducing pesticide over-application with map-based automatic boom section control on agricultural sprayers.

The use of precision agriculture technologies such as automatic guidance and map-based automatic boom section control on agricultural sprayers has increased substantially over the past few years. The purpose of these systems is to decrease pesticide application inaccuracy by reducing pass-to-pass overlaps or by turning boom sections off when the boom passes over previously covered areas or beyond field boundaries. The objectives of this study were to compare areas treated by a sprayer before and after the addition of an automatic boom section control system and determine if there was a relationship between field shape factors, specifically perimeter-to-area (P/A) ratio, and pesticide over-application. Coverage files were downloaded from a self-propelled agricultural sprayer with a 24.8 m boom divided into five manually controlled sections. Prior to the subsequent cropping season, automatic boom section control (seven sections) was installed on the sprayer. Application inaccuracy was calculated for the 21 study fields by comparing the actual sprayed area (based on boom section control state: on/off) versus the total projected field area. A comparison between the average percent over-application from fields during season one (12.4%) and season two (6.2%) revealed a significant reduction in off-target application. This reduction represents savings to agricultural producers, potentially justifying the purchase and implementation of this technology. Further analysis indicated an increasing trend in over-application for manual and automatic boom section control as the P/A ratio increased for the study fields. Over-application increased at a greater rate with manual boom section control, which suggests that as field inclusions (grassed waterways or other obstacles) increase, automatic boom section control will provide a greater opportunity for producers to reduce these errors.
Using Trauma-Informed Care in Practice: Evaluation of Internal Medicine Resident Training and Factors Affecting Clinical Use.

INTRODUCTION Trauma-informed care (TIC) acknowledges that childhood traumas can profoundly affect health outcomes and aims to creates a safe, nurturing medical environment. TIC curricula in graduate medical education are limited and lacking in assessment of the application of TIC in practice. METHODS This mixed-methods study followed implementation of a 4-hour required training session for 91 internal medicine residents at George Washington University Hospital. Pre- and posttests were administered to determine change in knowledge, attitude, and confidence. Six weeks after the training, individual participant interviews were conducted to ascertain how TIC is practiced in the clinical setting. RESULTS For the 47 participants with matched pre- and posttest data available, there was a statistically significant score improvement after the session on 13 of 16 items (excluding only 3 attitude items). Six themes emerged: 1) patient characteristics trigger recognition to utilize TIC; 2) time plays a critical role; 3) the acute medical setting is a barrier; 4) the patient-doctor relationship impacts TIC application; 5) concern about next steps influences TIC use; and 6) incorporating TIC requires repetition, practice, and supervisor support. CONCLUSION This study demonstrated that a 4-hour TIC session can promote growth in resident knowledge and confidence related to TIC. The findings highlight that TIC education needs to account for contextual factors that can impact its clinical application. A focus on work environment factors such as time, resources, and supervisory support can help to maximize TIC learning, retention, and application in practice.
Quality of Nutrition Environments, Menus and Foods Served, and Food Program Achievement in Oklahoma Family Child Care Homes

Child care environments foster children’s healthy eating habits by providing exposure to healthy foods and feeding practices. We assessed the healthfulness of nutrition environments, menu/meal quality, and the achievement of Child and Adult Care Food Program (CACFP) guidelines and best practices in Oklahoma CACFP-enrolled family child care homes (FCCHs) (n = 51). Two-day classroom observations were conducted. Healthfulness of classroom nutrition environments was assessed using the Environment and Policy Assessment and Observation (EPAO). Foods served to and consumed by children were quantified using the Dietary Observations in Child Care (DOCC) tool. Nutrient analysis was performed to determine total energy for foods listed on menus, served to, and consumed by children. Menu and meal food variety and CACFP Guideline Achievement Scores were determined. Average nutrition environment score was 11.7 ± 1.2 (61.5% of maximum possible score). Energy (kcals) from menus and consumed by children was insufficient to meet two-thirds of their daily reference intake. Children were exposed to 1.7 vegetables and 1.3 fruits per meal. CACFP Guideline Achievement Scores were 66.3% ± 7.8 for menus and 59.3% ± 7.6 for mealtimes. Similar to previous research, our findings indicate a need for improved FCCH nutrition practices. Tailored interventions for FCCHs are needed.
Potential of vegetation and woodland cover recovery during primary and secondary succession, a global quantitative review

Succession is a basic natural process of ecosystem recovery, it may start completely de novo (primary succession) or after serious disturbance of the previous ecosystem (secondary succession). Despite most reclamation and restoration approaches depending on it and despite extensive previous research, we found no worldwide review that would describe the pattern of vegetation cover and woody vegetation recovery in individual types of succession and explore major factors that affect the speed of vegetation recovery. To fill this gap we have searched world literature and extracted data about 244 succession series about total vegetation cover and 113 about woody vegetation cover. The rate of vegetation cover recovery is significantly slower during primary succession than during secondary succession, this however not apply to woody vegetation. The type of disturbance affects the speed of recovery, post‐mining sites recover fastest among primary succession and older fields were the fastest among secondary succession, the slowest one being succession in glacier retreats. Latitude, soil pH, the size of the disturbed area, temperature, and actual evapotranspiration affect the rate of vegetation recovery in primary succession, while only latitude affects secondary succession. Some other factors affect succession after a specific disturbance. The study shows that succession can be an effective tool to restore vegetation cover and woody vegetation on many occasions. We expect that differences in the nutrient availability determine differences in the rate of total vegetation cover recovery, while soil porosity (compaction) may be an important factor affecting woody vegetation recovery.
External force estimation for robotic manipulator base on particle swarm optimization

The safe disposal of nuclear waste in radioactive environment urgently needs cost-effective approaches. Toward this goal, this article developed a method to external force estimation based on the identified model without force sensors. Firstly, the mathematical model including joint friction was obtained and transformed into the linear combination of unknown parameter to be estimated. Secondly, the unknown parameters were identified based on the improved particle swarm optimization algorithm, the identification procedure was implemented by optimizing the excitation trajectories to excite joint motion and sampling relevant data. Identified results were compared with the biogeography-based optimization algorithm and the cuckoo search algorithm. Then, the identified dynamic parameter was applied to external force estimation. Finally, the verification of external force estimation has been carried out using the Kinova Jaco2 robot manipulator, and the experimental results showed that the external forces by the proposed method could be estimated with an root mean square error of 0.7 N.
Providing Validity Evidence for Ignite by Hatch

The authors of this study seek to provide practitioners with evidence to support the instructional value of Ignite by Hatch, a digital learning game designed for preschool children. Analyses were conducted using the entire population of three- and four-year-old children who used Ignite during the 2020-2021 academic year (n = 29,417) and included the use of descriptive statistics to explore patterns of growth and the Rasch measurement model to explore item difficulty. This chapter also features a preliminary crosswalk establishing the alignment between the domains, subdomains, and games presented within the Ignite game environment and the learning goals provided by the North Carolina Foundations for Early Learning and Development framework. Results suggest strong preliminary evidence in support of the instructional value of Ignite by Hatch. Further research is recommended to understand how knowledge and skill acquisition within the game environment translate to developmental growth outside of the gaming environment.
Summation of Multi-Finger Vibrotactile Stimuli

We have developed a vibrotactile glove that stimulates the fingertips of the wearer’s hand to convey grip force information while he/she is manipulating remote objects with a robotic hand. In this paper, we present a psychophysical experiment to examine how multi-finger vibrotactile stimulation is perceived by the user. Magnitude estimations of the overall strength of vibration were obtained using sinusoidal signals varying in amplitude and frequency. We have found that increasing the number of fingers stimulated increases the perceived vibration magnitude, but by a rule of diminishing returns. Additionally, we have found that finger separation and thumb “differentiation” are not factors in the magnitude judgements. By using multiple stimulation points, it may be possible to expand the perceived sensitivity range that is used to encode grip force information in a telemanipulation environment; thus a larger range or more refined range of force values can possibly be conveyed to the user.

Climate Change and Sustainability in Czech Wheat Production

The paper deals with the analysis of Czech wheat production and its determinants. We use the Just and Pope (1979) stochastic production function to estimate the effects of economic and weather variables, together with technological progress and climate change, on wheat yield in the Czech regions in the period 1961–2018. The results suggest that both economic and environmental factors play important roles in the wheat yield function. The output/input price ratio has a positive effect on the wheat yield. The effects of temperature and precipitation are month-specific and highly non-linear. Technological change also has a positive effect on yield, whereas climate change has a rather negative effect on wheat yield.
Endoscopic optic nerve decompression in traumatic optic neuropathy: our experience in a tertiary care centre

Background: Traumatic optic neuropathy (TON) a vision threatening disorder requires early diagnosis and prompt treatment. High dose steroid injections, optic nerve decompression or combined therapy are the available current treatment options. This study aims to determine the visual outcome with transnasal endoscopic optic nerve decompression in patients with TON having no improvement in vision despite high dose steroids.Methods: A prospective study was conducted at the department of ENT, government medical college Kozhikode; on patients who presented with loss of vision following history of trauma. All patients suspected of compressive optic neuropathy received injection methyl prednisolone (30 mg/kg/day) with assessment of vision and HRCT scan. Patients with deterioration or no improvement in vision despite high steroid therapy were taken up for trans-nasal endoscopic optic nerve decompression.Results: In our study 19 patients with TON underwent trans-nasal endoscopic optic nerve decompression. 11(57.9%) patients had improvement of vision, 7 (36.8%) patients had no improvement of vision and 1 (5.3%) patient had worsening of vision. The visual improvement was seen in 8 (80%) patients when treatment was initiated within 7 days and in only 3(33.3%) patients when treatment was initiated after 7 days. The visual acuity at presentation and time interval between trauma and intervention are factors that determine better visual outcomes.Conclusions: The decreased visual acuity in TON requires prompt treatment. High dose steroid must be started at once when it is suspected or diagnosed. The timely surgical intervention with trans-nasal endoscopic optic nerve decompression is a relatively safe and effective technique enabling better visual prognosis.
Gain enhancement and broadband using helical resonating metamaterial superstrate in stacked microstrip patch antenna

Metamaterial superstrate performs unique electromagnetic properties which are used in antenna design. In this article, a novel design of stacked with parasitic element multilayer rectangular microstrip patch antenna using single layer single turn helical resonator based on metamaterial superstrate is presented. The return loss, smith chart, impedance, radiation pattern, gain, VSWR, and directivity of such an antenna are studied. The possibility of increasing bandwidth, gain and directivity of the printed patch antenna using metamaterial superstrate is examined and verified with the realized antenna. The analysis of reduction in the size of helical resonator is given and it is found that maximum reduction in size is obtained at a metallic fill ratio of 0.2. The stacked antenna is realized and successfully tested and verified measured results with the simulated results. Investigation is performed related to gain enhance using metamaterial. Percentage bandwidth of antenna is approximately 64.84% with constant gain in specified bandwidth with good cross‐polarization. © 2014 Wiley Periodicals, Inc.

Prescription Audit and Dispensing Errors in the Outpatient Pharmacy of Tertiary Care Multispecialty Teaching Hospital

Background: Although errors occurring during the process of dispensing may affect the goal of the treatment, they also can be the significant cause of morbidity and mortality. There are only few published evidences which focuses on the errors of dispensing that occurs in the pharmacy. This study focuses on identifying the dispensing errors, impact of brand substitution on cost and DDIs. Objective: To identify the dispensing errors, impact of brand substitution on cost and DDIs. Methodology: Prospective observational study conducted over a period of eight weeks in outpatient hospital pharmacy of tertiary care multispecialty teaching hospital, Tamil Nadu. Prescriptions and medication bills and dispensed medicines are collected from the hospital pharmacy to obtain data required for the study. Prescription containing only medical devices were excluded from the study. Results: Out of 1010 prescriptions, dispensing errors were present in 419 (41.48%) prescriptions which consist of 557 errors. The errors include dispensing multi-pills to make the required dose is 3.77%,tablet splitting is 0.8%, incorrect strength is 1.07%, omission error due to unavailability is 31.4%,dispensing drugs with brands other than prescribed brands is 63.7%. Prescriptions which had more than three drugs were analyzed for drug-drug interactions (n=389). DDIs were present in 156(40.1%) prescriptions which had a total of 281 interactions. Conclusion: The brand substitution and omission errors are the major causes of dispensing errors. Brand substitution is not always recommended as it may have some adverse effects because of salt and excipients variation. Pharmacists are in the position to identify and reduce DDIs by discussing with the physicians.
