¿Cuál es el nivel de ruido existente Av. Av. 3 de Julio y sus intersecciones entre la calle Ambato y la Y del Indio Colorado de la ciudad de Santo Domingo?, el presente trabajo de investigación tiene como objetivo principal conocer el nivel de ruido existente en este sector de la ciudad, con el fin de determinar el alcance de su afectación y sobre todo sus fuentes, se realizó la evaluación correspondiente de acuerdo con la normativa TULSMA. y Decreto Ejecutivo N° 2393, aplicando la investigación de campo se midió la presencia de ruido ambiental y ocupacional, se requirió del uso de dosímetros calibrados y certificados para obtener información precisa. En esta investigación se estudió estas importantes intersecciones, siendo que, en cuanto a normativa ambiental sobrepasa el nivel tolerable con un diferencial de 10 decibeles en promedio, mientras que en referencia del ruido laboral esta intersección está por debajo de los niveles permisibles con al menos 9 decibeles en promedio, las posibles enfermedades subyacentes más comunes encontradas fueron el estrés, los dolores de cabeza que afectaban principalmente a la población comerciante permanente, y la actividad que mayor emisión de ruido produjo fue el tránsito vehicular, del mismo modo se identificó que el día que se produjo mayor contaminación acústica fue el sábado entre las 11:30 am hasta la 13:00 pm.

El objetivo fue Evaluación del Satisfacción Laboral y Rendimiento Productivo de los Piscicultores Comunitarios. El trabajo de investigación se realizó en las unidades productoras de truchas de la comunidad de Pacococha, distrito y provincia de Castrovirreyna. Las variables de estudio fueron la satisfacción laboral y la productividad. El tipo de investigación es básica. El nivel de la investigación es Correlacional. El método es descriptivo, cualitativo y cuantitativo, describiéndose las variables involucradas y analizando su incidencia e interrelación en función a la relación causa – efecto. El diseño de investigación fue descriptivo – correlacional. En la investigación se tuvo como población a 20 piscicultores entre trabajadores y jefes, y debido a que el número de unidades que la integraron resulto accesible en su totalidad, esta fue igual a la muestra, es decir los 20 piscicultores. Para el sustento de la parte teórica se consultó diferentes fuentes bibliográficas y para el trabajo de campo se aplicó cuestionarios a la muestra identificada, formulándose dos instrumentos, que fueron validados oportunamente por juicio de expertos, a fin de efectivizar su aplicación correspondiente, los instrumentos utilizados fueron los cuestionarios de encuesta de satisfacción laboral y productividad, donde cada pregunta fue realizada de acorde a las variables considerando sus dimensiones e indicadores, con los cuales se obtuvo la información pertinente de los trabajadores de las unidades productoras. Los resultados nos muestran un coeficiente de correlación de Pearson r = 0.672, con un nivel de significancia menor a 0,05 (p-valor = 0,001). Por lo tanto, al ser el p-valor significativo concluimos que existe correlación entre las variables de estudio, se acepta la hipótesis alterna con un nivel de confianza del 95%. Como conclusión principal se ha determinado a través de la investigación que la productividad del factor humano se relaciona de forma positiva y moderada con la satisfacción laboral del personal de producción de las piscigranjas, con un grado de relación del 45.2%.

Reading Social Science Methods

Contributor: Reisner

Publisher: University of Illinois Library - Urbana

License: CC BY-NC

Science has great potential to benefit society, but this potential comes with risks as well. Directed at introductory level social science and humanities majors, this textbook teaches the rules and limits of social science methods. Reisner starts from the assumption that it is not necessary to be able to do research to read and judge the soundness of research publications. The chapters guide students through an explicit set of rules for reading research articles developed from three common research methods: content analysis, survey research, and experimental method.

An Open Guide to Data Structures and Algorithms

Contributors: Bible, Moser, and Scarlato

Publisher: PALNI

License: CC BY

This textbook serves as a gentle introduction for undergraduates to theoretical concepts in data structures and algorithms in computer science while providing coverage of practical implementation (coding) issues. The field of computer science (CS) supports a multitude of essential technologies in science, engineering, and communication as a social medium. The varied and interconnected nature of computer technology permeates countless career paths making CS a popular and growing major program. Mastery of the science behind computer science relies on an understanding of the theory of algorithms and data structures. These concepts underlie the fundamental tradeoffs that dictate performance in terms of speed, memory usage, and programming complexity that separate novice programmers from professional practitioners.

Vacuum systems are critical to many industries. They are vital to establishing required process pressures, establishing a clean process environment, and removing reaction by-products from the process chamber. This text, a revision and expansion of David Hata’s Introduction to Vacuum Technology published in 2008, addresses basic topics in vacuum technology for individuals tasked with maintaining vacuum systems and instructors teaching technician-level courses. The topics are carefully curated to the needs of technicians in a production environment and the types of vacuum systems used, and the accompanying laboratory manual and instructor’s guide support the delivery of lecture-laboratory courses.

Natural Resources Sustainability: An introductory synthesis

Contributor: Lant

Publisher: Utah Education Network Digital Press with Pressbooks

License: CC BY-NC-SA

This text has evolved from 20 semesters teaching the undergraduate courses Geography, People, and the Environment and Environment and Society. It is designed for freshmen through junior-level courses at community, junior and four-year colleges and universities in the United States. Focused upon the dilemma of environmental sustainability, geography and the emergent field of ecological economics are emphasized in a trans-disciplinary framework. It provides—in a one semester or one quarter undergraduate course that requires no prerequisites—a fundamental background in the essentials students need to deal with natural resource and environmental issues as an informed citizen while building a foundation for further study.

Finding Balance: Collaborative Workflows for Risk Management in Sharing Cultural Heritage Collections Online

Contributors: Hintz, Kowalski, Quigley, and Bailey

Publisher: University of Kansas Libraries

License: CC BY-NC

Digitizing rare and unique historical documents so they can be shared online is mission-critical work for most cultural heritage institutions, but it can be difficult to complete this work, especially intellectual property rights management, at a scale that matches user demand. The authors of this open educational resource offer guidance for creating scalable, cross-functional workflows using a risk-management approach that increases efficiency and distributes responsibility for rights assessment work more equitably across stakeholders. It includes advice for navigating knowledge gaps, building an engaged team with the right skillsets, reimagining workflows, and rethinking traditional archival processing workflows to build capacity for rights analysis during arrangement and description. Each chapter includes a helpful exercise for implementing this guidance in your own institution.
