Os impactos tecnológicos da implantação da nota fiscal eletrônica: um estudo de casos múltiplos

Increasingly, the Information Technology is used in the society, including the private, public and third sector organizational context. Technological tools are created in order to speed, automate, control and monitor processes. These technologies generate impacts on areas that permeate their use and the objective of this study is to investigate the implementation process of the Eletronic Invoice and the impacts arising from this technological tool in companies. For that, case studies have been conducted in three companies that emit and receive Eletronic Invoice, in a Information System consultancy, that provides softwares of Eletronic Invoice, and in a State Tax Department. Data collection was performed with organizations representatives through electronic questionnaires. The study concludes that it is expected, by the investigated organizations, that the tool reaches the benefits offered by the Tax Administration. However, these benefits have not been identified yet and neither have the use of methodologies in order to identify them. Moreover, the main impact found was the need for better training and participant´s technical qualification, followed by reducing printing costs and paper purchase

Versuch zur Erfassung motivationsrelevanter Faktoren im naturwissenschaftsbezogenen Unterricht in der Schuleingangsstufe

Eine Fragebogenentwicklung wird vorgestellt, die Lernfreude, Anstrengungsbereitschaft, Bedeutung von Lernen und Zufriedenheit mit der didaktischen Unterrichtsgestaltung operationalisiert und an Kindern im Alter von 7-8 Jahren überprüft. Erste Ergebnisse weisen auf erfolgversprechende Weiterentwicklungsmöglichkeiten hin. Es scheint möglich auf dieser Stufe ökonomisch und flächendeckend reliable Daten zu erheben. (DIPF/Orig.)

Patterns of sedentary behavior : insights from observational and experimental studies on body composition and energy expenditure

It is recognized that sedentary behavior (SB) has deleterious effects on numerous health outcomes and it appears that physiological mechanisms underlying these harms are distinct from the ones explaining moderate-to-vigorous physical activity (MVPA) benefits. Sedentary behavior represents a large portion of human’s life and is increasing with technological development. A new current of opinion supports the idea that the manner SB is accumulated plays an important role. This dissertation presents six research studies conducted under the scope of SB. In the methodological area, the first study highlighted the magnitude of potential errors in estimating SB and its patterns from common alternative methods (accelerometer and heart rate monitor) compared to ActivPAL. This study presented the accelerometer as a valid method at a group level. Two studies (2 and 5) were performed in older adults (the most sedentary group in the population) to test the associations for SB patterns with abdominal obesity using accelerometry. The findings showed positive graded associations for prolonged sedentary bouts with abdominal obesity and showed that those who interrupted SB more frequently were less likely to present abdominal obesity. Therefore, public health recommendations regarding breaking up SB more often are expected to be relevant. The associations between sedentary patterns and abdominal obesity were independent of MVPA in older adults. However, the low MVPA in this group makes it unclear whether this independent relationship still exists if highly active persons are analysed. Study 3 inovates by examining the association of SB with body fatness in highly trained athletes and found SB to predict total fat mass and trunk fat mass, independently of age and weekly training time. Study 4 also brings novelty to this research field by quantifying the metabolic and energetic cost of the transition from sitting to standing and then sitting back down (a break), informing about the modest energetic costs (0.32 kcal·min−1). Finally, from a successful multicomponent pilot intervention to reduce and break up SB (study 6), an important behavioral resistance to make more sit/stand transitions despite successfully reducing sitting time (~ 1.85 hours·day-1) was found, which may be relevant to inform future behavioral modification programs. The present work provides observational and experimental evidence on the relation for SB patterns with body composition outcomes and energy regulation that may be relevant for public health interventions.

El capital intelectual y su relación con la innovación en la universidad CES

En la sociedad actual del conocimiento las universidades tienen la responsabilidad de generar conocimiento e innovaciones para ofrecer soluciones a problemas de comunidades de interés. Para lograrlo las universidades deben enfocarse en su activo más importante, su capital intelectual. Hasta ahora las investigaciones relacionadas con el capital intelectual y la innovación en las universidades, son limitadas a pesar de ser un elemento estratégico para la dirección de estas organizaciones, ya que estos aspectos le representan valor en el tiempo, por tanto esta investigación busca establecer cuál es la relación que existe entre el capital intelectual y la innovación en la Universidad CES. El objetivo de esta investigación era identificar el grado de relación entre capital intelectual e innovación en la Universidad CES. La metodología del estudio, es un estudio cuantitativo, de tipo descriptivo explicativo, con un diseño transversal, que permitió establecer el efecto del capital intelectual sobre la innovación de la Universidad CES. La población del fueron los directivos, líderes de los grupos de investigación y los coordinadores de investigación de la Universidad CES. Según los resultados obtenidos, este estudio determinó que el capital intelectual no tiene una relación estadísticamente significativa con la innovación personal de la Universidad CES y se determinó también que las tres dimensiones del capital intelectual tienen una relación estadísticamente significativa con los resultados de la innovación en la Universidad CES. El principal aporte de este estudio fue ofrecer evidencias sobre el capital intelectual como una de las principales fuentes de innovación para la Universidad.
