The Forest for the Trees: Gifford Pinchot’s Principles of Conservation

Murray, Leslie M. 01 August 2018 (has links)
Gifford Pinchot’s principles of conservation embody the democratic principles of the United States and how those principles remain relevant today. The three central characteristics of Pinchot’s principles of conservation are wise use, avoiding waste, and securing the autonomy of democratic citizens by preventing monopolistic control over our natural resources. Pinchot’s aim place democratic aspirations at the fore. A case study of the environmental degradation revealed throughout the life-cycle of the cellular phone exhibits how Pinchot’s principles are not only relevant, but sorely needed today. Furthermore, this case study also reveals how globalized corporatism has become the antithesis of the democratic aims of the global citizenry. Pinchot’s principles advise us to check the global monopolies of multinational corporations and greed for greed’s sake to secure a democratic future for the most people, in perpetuity. Though his principles are often neglected, they are more relevant now than ever.

Do outro, alunos cada vez mais conectados e deslum-brados com seus smartphones que disponibilizam inúmeras oportunidades de acesso à informação e à comunicação. Esta pesquisa busca discutir e vivenciar este embate atra-vés de uma sequência didática estruturada para utilização do smartphone em sala de aula, visando a aprendizagem significativa de conteúdos da Física. Para tanto, estrutu-ramos um aplicativo utilizando a plataforma MIT App Inventor, onde abordamos os conteúdos da eletrodinâmica.

On the one hand teachers, coordina-tors and directors, often unprepared to deal with the technological avalanche smothers the teaching-learning process. On the other, students increasingly connected and daz-zled with their smartphones that provide numerous opportunities for access to infor-mation and communication. This research aims to discuss and experience this clash through a structured instructional sequence to use the phone in the classroom with a view to significant learning of physics content. Therefore, we designed an application using the MIT App Inventor platform where we discuss contents of electrodynamics. The preparation of previous instruments was based on data collected through question-naires, and these as theoretical reference the Meaningful Learning of David Ausubel.

Användbarhet i smartphones : En studie om de ledande operativsystemen / Usability in smartphones : A study of the leading operating systems

Svensson, Jonas, Nabrink, Adam January 2013 (has links)
Utvecklingen av mobiltelefoner och mobiltelefonmarknaden ökar i snabb takt. Bara i Sverigesåldes ca 3.8 miljoner mobiltelefoner år 2011, över hälften av dessa var smartphones.Användning av en ny teknisk enhet kan i många fall vara problematisk till en början och olikastandarder kan utvecklas. Därför frågar vi oss hur lätt det är att byta mellan idag ledandesystem; hur användarvänliga är de för nya användare av andra system? Med hjälp avanvändartester testar vi systemen Android och iOS. Vi lyfter fram områden där systemenvisar brister samt lämnar förbättringsförslag, samt diskuterar om områden där det enasystemet gjort en lösning på ett mer välfungerade sätt. Datainsamlingen skedde genom attgöra användartester på våra testobjekt, HTC one X samt iPhone 4, en testperson i taget ochsammanlagt åtta personer. Testpersonerna fick en enkät med uppgifter att utföra påtestobjektet, denna uppgift fick sedan en svårighetsgradering samt om möjligt en kommentarav testpersonerna. Testerna resulterade i olika problem hos testobjekten, men det slutgiltigaresultatet visade i en hög användbarhet i båda fallen. Vi ser möjligheter till att förbättra bådasystemen men inom olika områden. / The evolution of mobile phones and mobile phone market is growing rapidly. Sweden alonesold approximately 3.8 million mobile phones in 2011, over half of which were smartphones.The use of a new technological device can often be problematic to begin with and differentstandards can developed. Therefore, we ask ourselves how easy it is to switch betweentoday's leading systems; how user-friendly are them for the new users of other systems?With the help of user testing, we test the systems Android 4 and iOS 6. We highlight areaswhere systems show deficiencies and provide suggestions for improvement; we also discussareas where one system has a solution to a more well-functioning manner. Data collectionwas done by usability testing on our test devices, the HTC one X and the iPhone 4, one testperson at a time and a total of eight people. The subjects were given a questionnaire withinformation to perform on the test object, this task were then given a difficulty rating and, ifpossible, a comment of the test subjects. The tests resulted in various problems of the testobjects , but the final result showed a high level of usability in both cases. We seeopportunities to improve both systems but in different areas.

Medical Education in Infectious Diseases. Using Smartphone Apps for Active Learning

Valdez, Luis, Gray, Andrea, Ramos, Gaston, Siu, Hugo January 2017 (has links)
Background Active Learning using smartphone technology can be implemented as a tool for teaching medical students (MS) and residents (Rs). The use of technology would increase participation and enhance student learning by engaging them in solving ID clinical case scenarios. Our objective was to describe the methods used and to share the opinions of the users of such active learning methods. Methods The smartphone applications used were Socrative and WhatsApp. We used Socrative during the Universidad Peruana de Ciencias Aplicadas (UPC) ID course for MS in two different ways. In selected lectures (4 of 32), teacher paced questions were asked based on clinical scenarios related to the topic reviewed, and by voluntary homework questionnaires (student paced). At the British American Hospital (BAH) Medicine Department (MS and Rs) Socrative was used similarly: during some noon lectures (teacher paced questions) and during the baseline MS exam and Rs mid-year exam and voluntary homework questions (student paced). WhatsApp is currently used at the BAH with questions send from Monday to Friday. MS /Rs answer individually via WhatsApp to the mentor in charge. The right answer is given the next day. Questions using WhatsApp deal with recent cases seen at the Wards or in the outpatient clinic, and are designed so that the MS/Rs must do quick literature searches in order to provide the right answer. Results Forty-one MS/Rs answered the survey on Socrative use, 25 of 48 (52%) of UPC MS and 16 (89%) MS/Rs from the BAH. Forty (97%) believed using Socrative had influenced their learning and all but 2 believed it promoted participation from the class. 36 (87.8%) would like to have Socrative used in other lectures and 35 (85%) in other courses. Only one person voted against Socrative use in courses or lectures. With regards to WhatsApp use 16 MS/Rs from BAH answered the survey. Six had used before WhatsApp as a teaching tool. All felt the methodology was useful for learning and promoting reading and would recommend this methodology to promote learning on a student paced way. Conclusion Socrative and WhatsApp can be used for teaching ID through MS/Rs smartphones. Most MS/Rs who were surveyed recommended the use of such methods in their education.

Improving a Smartphone Wearable Mobility Monitoring System with Feature Selection and Transition Recognition

Capela, Nicole Alexandra January 2015 (has links)
Modern smartphones contain multiple sensors and long lasting batteries, making them ideal platforms for mobility monitoring. Mobility monitoring can provide rehabilitation professionals with an objective portrait of a patient’s daily mobility habits outside of a clinical setting. The objective of this thesis was to improve the performance of the human activity recognition within a custom Wearable Mobility Measurement System (WMMS). Performance of a current WMMS was evaluated on able-bodied and stroke participants to identify areas in need of improvement and differences between populations. Signal features for the waist-worn smartphone WMMS were selected using classifier-independent methods to identify features that were useful across populations. The newly selected features and a transition state recognition method were then implemented before evaluating the improved WMMS system’s activity recognition performance. This thesis demonstrated: 1) diverse population data is important for WMMS system design; 2) certain signal features are useful for human activity recognition across diverse populations; 3) the use of carefully selected features and transition state identification can provide accurate human activity recognition results without computationally complex methods.

Aplicaciones de los sensores de los smartphones a la didáctica de la física experimental

Giménez Valentín, Marcos Herminio 19 June 2017 (has links)
Traditionally, Physics laboratory practices have two objectives. On the one hand, students reinforce the concepts that they have acquired in theory lessons. On the other hand, they get used to the experimental techniques. However, students sometimes consider that the practices are routine and of little interest. Several resources, based on Information and Communication Technologies, have been used to deal with this problem. The smartphones of the students themselves incorporate various sensors. Free available applications are able to control the sensors, acquire data and transmit them. The smartphones become measuring tools. The main objective of this Thesis is to propose new experiments for Physics laboratories that take advantage of this way of using smartphones. A collection of works is presented as a set of publications. The acceleration sensor enables us to study: the free and damped oscillations of the smartphone; the normal modes of a coupled two dimensional vibrating system of smartphones; and the mechanical beat. The ambient light sensor is used to analyze the efficiency of several types of optical sources; the dependence of the illuminance on the distance to the source is also studied. Finally, the microphone enables us to characterize the acoustic beat phenomenon. The new experiments are focused on university and high school students. Our surveys show the higher rating given to this type of experiences with respect to their traditional alternatives. / Tradicionalmente, el objetivo de las prácticas de laboratorio de las asignaturas de Física es doble: por una parte, que los estudiantes refuercen los conocimientos adquiridos en las clases de teoría; por otra, que se habitúen a las técnicas experimentales. Sin embargo, los alumnos consideran que en ocasiones las prácticas son rutinarias y poco interesantes. Para paliar este problema, se ha hecho uso de diversos recursos basados en las Tecnologías de la Información y las Comunicaciones. El objetivo fundamental de esta Tesis es proponer diversos experimentos de Física en los que se utilizan como herramientas de medida los sensores de que disponen los smartphones de los propios estudiantes, aprovechando las aplicaciones gratuitas existentes para el control de estos sensores y para la toma y transmisión de los datos obtenidos. Con este fin se ha realizado un conjunto de trabajos, recogidos en esta Tesis en formato de compendio de publicaciones, en los que se proponen nuevas experiencias de laboratorio de Física con smartphones. En ellas se saca partido del sensor de aceleración para el estudio de las oscilaciones libres y amortiguadas de un smartphone, de los modos de vibración de dos acoplados, y del batido mecánico; del sensor de luz ambiente para el análisis de la eficiencia de diversos tipos de fuente, y de la dependencia de la iluminancia con la distancia; y, finalmente, del micrófono para la caracterización del fenómeno del batido acústico. Las experiencias diseñadas están enfocadas a estudiantes universitarios y de educación secundaria. Las encuestas realizadas muestran la mayor califica-ción otorgada a este tipo de experiencias con respecto a sus alternativas tradicionales. / Tradicionalment, l'objectiu de les pràctiques de laboratori de les assignatures de Física és doble: d'una banda, que els estudiants reforcen els coneixements adquirits en les classes de teoria; per una altra, que s'habituen a les tècniques experimentals. No obstant això, els alumnes consideren que en ocasions les pràctiques són rutinàries i poc interessants. Per a pal¿liar aquest problema, s'ha fet ús de diversos recursos basats en les Tecnologies de la Informació i les Comunicacions. L'objectiu fonamental d'aquesta Tesi és proposar diversos experiments de Física en els quals s'utilitzen com a eines de mesura els sensors de què disposen els smartphones dels propis estudiants, aprofitant les aplicacions gratuïtes existents per al control d'aquests sensors i per a la presa i la transmissió de les dades obtingudes. Amb aquesta finalitat s'ha realitzat un conjunt de treballs, recollits en aquesta Tesi en format de compendi de publicacions, en els quals es proposen noves experiències de laboratori de Física amb smartphones. En aquestes es trau partit del sensor d'acceleració per a l'estudi de les oscil¿lacions lliures i esmorteïdes d'un smartphone, dels modes de vibració de dos acoblats, i del batut mecànic; del sensor de llum ambiente per a l'anàlisi de l'eficiència de diversos tipus de font, i de la dependència de la il¿luminancia amb la distància; i, finalment, del micròfon per a la caracterització del fenomen del batut acústic. Les experiències dissenyades estan enfocades a estudiants universitaris i d'educació secundària. Les enquestes realitzades mostren la major qualificació atorgada a aquest tipus d'experiències pel que fa a les seues alternatives tradicionals. / Giménez Valentín, MH. (2017).
