Freshman Orientation Activity

The purpose of this paper is to discuss the experience and positive results in this year’s freshmen orientation at Rochester Institute of Technology (RIT). Before classes started in the fall freshman in Electrical, Computer and Telecommunications Engineering Technology (ECTET) programs were asked to work with faculty as they programmed an inexpensive robot and built maps of the RIT campus for the robots to navigate. The paper discusses these activities in detail, provides the tutorials that were developed and discusses the student survey completed after the orientation. The goals met in the orientation were: faculty-student interaction, student-student interaction, increased student knowledge of the campus, team participation by all, students meeting the office staff, and students working with their advisors to review their schedule before classes began

Gestión Administrativa y Desempeño Laboral de los Trabajadores de las Concesiones Mineras de la Provincia de Chanchamayo 2021

La presente investigación tendrá como título “Gestión administrativa y desempeño laboral de los trabajadores de las concesiones mineras de la provincia de Chanchamayo 2021”. Tuvo como problema: ¿Qué relación existe entre la gestión administrativa y el desempeño laboral de los trabajadores de las concesiones mineras de la provincia de Chanchamayo 2021?. El objetivo general: Determinar la relación que existe entre la gestión administrativa y el desempeño laboral de los trabajadores de las concesiones mineras de la provincia de Chanchamayo 2021. La hipótesis: Existe relación directa entre la gestión administrativa y el desempeño laboral de los trabajadores de las concesiones mineras de la provincia de Chanchamayo 2021. Es así que, se empleo el enfoque cuantitativo (deductivo), el método general a emplear fue descriptivo, de tipo aplicada, nivel correlacional, y diseño no experimental, asimismo, la población estuvo constituida por las 6 concesiones mineras de la provincia de Chanchamayo, y la muestra serán elegida por conveniencia o muestreo no probabilístico. El instrumento de medición de las variables fue el cuestionario, para la demostración de los objetivos y la prueba de hipótesis, se empleó el estadístico Shapiro Wilk (estadístico inferencial). Se concluye que, Existe relación directa entre la gestión administrativa y el desempeño laboral de los trabajadores de las concesiones mineras de la provincia de Chanchamayo 2021. Consiguientemente se observa una correlación positiva muy alta con un “r” = 0,927, lo cual nos permite aseverar que, mientras exista una buena gestión administrativa, existirá mayor desempeño laboral de los trabajadores de las concesiones mineras

Initial Fe/O enhancements in large, gradual, solar energetic particle events:observations from wind and Ulysses

Shocks driven by fast coronal mass ejections (CMEs) are the dominant particle accelerators in large, “gradual” solar energetic particle (SEP) events. In these events, the event-integrated value of the iron-to-oxygen ratio (Fe/O) is typically ∼ 0.1, at least at energies of a few MeV/nucleon. However, at the start of some gradual events, when intensities are low and growing, initially Fe/O is ∼ 1. This value is also characteristic of small, “impulsive” SEP events, in which particle acceleration is due to magnetic reconnection. These observations suggested that SEPs in gradual events also include a direct contribution from the flare that accompanied the CME launch. If correct, this interpretation is of critical importance: it indicates a clear path to interplanetary space for particles from the reconnection region beneath the CME. A key issue for the flare origin is “magnetic connectedness”, i.e., proximity of the flare site to the solar footpoint of the observer’s magnetic field line. We present two large gradual events observed in 2001 by Wind at L1 and by Ulysses, when it was located at > 60∘ heliolatitude and beyond 1.6 AU. In these events, transient Fe/O enhancements at 5 – 10 MeV/nucleon were seen at both spacecraft, even though one or both is not “well-connected” to the flare. These observations demonstrate that an initial Fe/O enhancement cannot be cited as evidence for a direct flare component. Instead, initial Fe/O enhancements are better understood as a transport effect, driven by the different mass-to-charge ratios of Fe and O. We further demonstrate that the time-constant of the roughly exponential decay of the Fe/O ratio scales as R 2, where R is the observer’s radial distance from the Sun. This behavior is consistent with radial diffusion. These observations thus also provide a potential constraint on models in which SEPs reach high heliolatitudes by cross-field diffusion

Dynamics of the Earth's particle radiation environment

The physical processes affecting the dynamics of the Earth's particle radiation environment are reviewed along with scientific and engineering models developed for its description. The emphasis is on models that are either operational engineering models or models presently under development for this purpose. Three components of the radiation environment, i.e., galactic cosmic rays (GCRs), solar energetic particles (SEPs) and trapped radiation, are considered separately. In the case of SEP models, we make a distinction between statistical flux/fluence models and those aimed at forecasting events. Models of the effects of particle radiation on the atmosphere are also reviewed. Further, we summarize the main features of the models and discuss the main outstanding issues concerning the models and their possible use in operational space weather forecasting. We emphasize the need for continuing the development of physics-based models of the Earth's particle radiation environment, and their validation with observational data, until the models are ready to be used for nowcasting and/or forecasting the dynamics of the environment
