Gun control and suicide: The impact of state firearm regulations, 1995-2004

Suicide is a major cause of preventable death. Restricting access to lethal means has been identified as an effective approach to suicide prevention, and firearms regulations are one way to reduce gun availability. This study examines the relationship between state firearms regulations and suicide among males, using negative binomial regression and state panel data for the years 1995–2004. Results suggest that firearms regulations which function to reduce overall gun availability have a significant deterrent effect on suicide, while prohibited persons categories have less of an effect. Overall, the results suggest that gun control measures such as permit and licensing requirements might have public health benefits.suicide; guns; panel data; state regulations

Student Engagement and Motivation in Post-Pandemic Higher Education Mathematics: A Concept Paper

During the past three years mathematics educators have had to adjust to the online education system and develop new approaches strategies and practices to keep students engaged and motivated Student engagement and motivation have been established in existing research as vital aspects of education To promote engagement and motivation during the pandemic mathematics educators have focused on positive working relationships with students highlighting values such as care and empathy Mathematics educators have also adopted various technological tools to enhance student engagement and motivation As institutions have begun to reintroduce face-to-face classes in the post-pandemic era there is a need to re-examine these approaches and how they may be sustained or improved A significant gap that has remained unexplored in the literature is how mathematics educators maintain or enhance student engagement and motivation upon transitioning to face-to-face or hybrid classes in the post- pandemic era This concept paper is centered on this research gap with recommendations for theory and practice based on current knowledge regarding higher education students motivation and engagement in mathematic

Space-time modeling of soil moisture: Stochastic rainfall forcing with heterogeneous vegetation

The present paper complements that of Isham et al. (2005), who introduced a space-time soil moisture model driven by stochastic space-time rainfall forcing with homogeneous vegetation and in the absence of topographical landscape effects. However, the spatial variability of vegetation may significantly modify the soil moisture dynamics with important implications for hydrological modeling. In the present paper, vegetation heterogeneity is incorporated through a two dimensional Poisson process representing the coexistence of two functionally different types of plants (e.g., trees and grasses). The space-time statistical structure of relative soil moisture is characterized through its covariance function which depends on soil, vegetation, and rainfall patterns. The statistical properties of the soil moisture process averaged in space and time are also investigated. These properties are especially important for any modeling that aggregates soil moisture characteristics over a range of spatial and temporal scales. It is found that particularly at small scales, vegetation heterogeneity has a significant impact on the averaged process as compared with the uniform vegetation case. Also, averaging in space considerably smoothes the soil moisture process, but in contrast, averaging in time up to 1 week leads to little change in the variance of the averaged process

Simulación Desarrollada En Simulink De Un Sistema Mecanico Masa-Resorte-Amortiguador Con Fuerza Externa Variable

This research is about the simulation of a mechanical system consisting of a mass, a spring, a shock absorber and the application of an external force, allows to understand the analytical and numerical behavior of the differential equation that governs said event. In this analysis the differential equation is obtained and solved analytically and numerically, for the numerical solution Simulink was used, since this allows the design and simulation of a system of textual and graphic form, which are fundamental elements for programming and operation of a system. This research is about the simulation of a mechanical system consisting of a mass, a spring, a shock absorber and the application of an external force, allows to understand the analytical and numerical behavior of the differential equation that governs said event.

Anesthetic Management of Patients with Post COVID-19 Syndrome: A Quality Improvement Project

Background: Millions of people have been infected with the novel Coronavirus 2019, creating a global pandemic. Despite the high mortality rate of this viral infection, millions of people have recovered, and are now presenting for surgical procedures with a history of COVID-19 infection. Residual effects of COVID-19 infection have been observed for several after diagnosis and are referred to as post COVID-19 syndrome. Post COVID-19 sequela can alter multisystem physiological processes that may alter anesthetic care throughout the perioperative period. Objectives: The purpose of this quality improvement project is to improve anesthesia provider knowledge on the management of patients who have post COVID-19 syndrome. Methods: The primary methodology of the proposed quality improvement project is to administer an educational intervention to anesthesia providers which discusses the management of patients undergoing elective surgery and have a history of COVID-19 infection. Pre- and post- assessment surveys will be used to measure the effectiveness of the educational intervention. Results: Overall, there was an improvement in anesthesia provider knowledge following the educational intervention. Participants also answered they would “always” or “often” consider additional pre-operative testing compared to “sometimes” prior to the educational intervention

Lavender Aromatherapy Compared to Midazolam For Quality Improvement Of Preoperative Anxiety In Elderly Surgical Patients: An Educational Module

Impact: Investigation into the anxiolytic effects of lavender aromatherapy across several patient populations, application types, and outcome measures establish that lavender oil relieves anxiety, reduces mental stress, provides sedation, and promotes good sleep. Background: Studies have investigated the link between age and the occurrence of undesired responses to premedication with agents of the benzodiazepine drug class. This link is explained by age-related pathophysiologic changes that occur as a function of aging. Despite numerous knowledge-based concerns, benzodiazepines prevail among the top psychotropic medications prescribed in elderly patients aged between 65 and 80 years. Objective: This quality improvement project aims to enhance anesthesia providers\u27 knowledge, beliefs, and attitude regarding the value of aromatherapy with lavender oil as an affordable, safe, and effective alternative to midazolam administration for preoperative anxiolysis in elderly surgical patients. Methods: An extensive literature search was conducted to synthesize studies relevant to the PICO question and create an evidence-based educational module for virtual presentation. An anonymous online platform was used to distribute the project’s intervention and survey components to a sample of anesthesia providers working at a South Florida level-1 trauma center and to record and statistically analyze data. Results: Collectively, the evidence-based literature presented by this project positively impacts the perioperative care of older adults, as it demonstrates lavender aromatherapy as a beneficial alternative to midazolam administration for improved management of preoperative anxiety in elderly surgical patients. Discussion: Analysis of the pre-and post-survey results reveals that this quality improvement project met the objective of expanding anesthesia providers’ knowledge and understanding of the use of lavender oil aromatherapy to optimize preoperative anxiety and care outcomes in elderly surgical patients. As a result, they will be more competent and effective in helping elderly patient populations achieve relief from anxiety before surgery and improved perioperative care outcomes. The small sample size, short project duration, and online delivery platform were limitations of this project
