MAC Design for WiFi Infrastructure Networks: A Game-Theoretic Approach
2011
In WiFi networks, mobile nodes compete for accessing a shared channel by means of a random access protocol called Distributed Coordination Function (DCF). Although this protocol is in principle fair, since all the stations have the same probability to transmit on the channel, it has been shown that unfair behaviors may emerge in actual networking scenarios because of non-standard configurations of the nodes. Due to the proliferation of open source drivers and programmable cards, enabling an easy customization of the channel access policies, we propose a game-theoretic analysis of random access schemes. Assuming that each node is rational and implements a best response strategy, we show that…
A preliminary study of agility in business and production - Cases of early-stage hardware startups
2018
[Context] Advancement in technologies, popularity of small-batch manufacturing and the recent trend of investing in hardware startups are among the factors leading to the rise of hardware startups nowadays. It is essential for hardware startups, companies that involve both software and hardware development, to be not only agile to develop their business but also efficient to develop the right products. [Objective] We investigate how hardware startups achieve agility when developing their products in early stages. [Methods] A qualitative research is conducted with data from 20 hardware startups. [Result] Preliminary results show that agile development is known to hardware entrepreneurs, howe…
La Comprensión Asíncrona de las Emociones Básicas: un Estudio Longitudinal con Niños de 3 a 5 Años
2021
El presente estudio tiene como finalidad explorar la trayectoria evolutiva de la comprensión de cuatro emociones en niños de tres a cinco años. Sabemos que los niños identifican las expresiones faciales y después entienden la causa de las emociones, pero ¿las emociones se comprenden a la vez, en el mismo momento evolutivo? Para llevar a cabo este estudio se evaluó de forma longitudinal a un grupo de 103 niños y niñas entre los 3 y los 5 años. A través del Test de Comprensión Emocional se midieron los componentes de identificación de la expresión emocional y el conocimiento de la causa de cuatro emociones –tristeza, alegría, enfado y miedo– a lo largo de los tres años. Los resultados confirm…
Best practices in the Japanese software market
2007
Globalization of software markets is driving software firms to seek market share and growth opportunities from leading software markets in the world. As the second largest software market, Japan offers high growth potential for foreign software firms. In Japan, the information and communication technology industry is the largest market sector, and the size of the software market in Japan was US$131.8 billion in 2004. Despite great opportunities in the Japanese market, entering the market and conducting successful business there can be difficult due to cultural differences between Japan and Western countries. In this multi-case study we focus on nine software firms in order to examine the be…
An Examination of the Structure of the Career Decision Self-Efficacy Scale (Short Form) Among Italian High School Students
2013
This study aims to evaluate the factor structure of Career Decision Self-Efficacy scale-short form in a sample of Italian high school adolescents. confirmatory factor analysis (CFA) was used to test the degree to which a one-factor structure and a five-factor structure provided the best fit. In view of available research the five-factor structure was expected to provide the best fit. Moreover, factorial invariance in males and females was tested. It was expected to be invariant across groups. As expected the five-factor structure showed a better fit than the one-factor model and the factorial invariance resulted invariant across boys and girls.
Factor structure and stability of a quality questionnaire within a postgraduate program
2017
En este trabajo se describe un instrumento basado en el uso de una técnica de análisis factorial con el fin de medir la calidad de la educación a través de una muestra de estudiantes de postgrado de una universidad pública española. El instrumento tiene unas aceptables propiedades psicométricas (fiabilidad y validez). En cuanto a la solución factorial, tres dimensiones principales se han determinado: la importancia dada a la materia; recursos educativos y conocimiento de la materia (anterior y posterior). Es importante destacar que estas tres dimensiones se han detectado consistentemente en todo el análisis factorial: muestra total y cursos separados. Estas tres dimensiones deben ser consid…
A Fair Share of Work: Is Fairness of Task Distribution a Mediator Between Transformational Leadership and Follower Emotional Exhaustion?
2019
Drawing on social resource theory and the norm of equity, this research proposes fairness of task distribution as a mediating mechanism of the well-established relationship between transformational leadership and followers’ well-being, conceptualizing the latter as low emotional exhaustion. Using data from 479 German employees in a three-wave longitudinal study, we found transformational leadership to be related to fair task distribution over time. The perceived fairness of task distribution mediated the relationship between transformational leadership and follower emotional exhaustion (structural equation modeling) when excluding stabilities. Our results also show a reverse causation effec…
Creativity, Culture and Urban Strategies: A Fallacy in Cultural Urban Strategies
2012
Two fields of knowledge have been of special importance for the emergence of culture-led urban planning in Norwegian cities: one concerns the understanding of the potential of culture as an economic driving force in urban regeneration, while the other focuses on the emergence of the concept of the “creative class” and has drawn attention to the importance of competence and creativity in urban development. Despite clear connections between the two fields, it may appear that false connections have been made in regeneration strategies in a number of cities. Based on analyses of the culture-led urban strategy of Kristiansand, a small Norwegian city, these knowledge fields are discussed and it i…
FAMILY FIRMS: WELL-BEING OF EMPLOYEES AND ENTREPRENEURS. FAMILY RELATIONSHIPS AND WORK-RELATED STRESS
2014
The general aim of the present dissertation is to gain more insight into the phenomenon of family firms, the well-being of employees and entrepreneurs and the role of family relationships at work. These objectives have been pursued by means of three empirical studies presented in the three chapters respectively: Chapter 1 focuses on comparing the employees of family and non-family firms to identify clearly the distinctive features. Chapter 2 focuses on the Job demands-resources model and on the role of the emotional experience as an important variable in attempt to understand whether there is a different pattern of relationships in the model depending on the fact that the people work with o…
Repaso a la evidencia isotópica sobre alimentación en la prehistoria valenciana durante el Mesolítico y el Neolítico
2016
Los análisis de isótopos estables son una herramienta fundamental a la hora de reconstruir la alimentación de poblaciones prehistóricas. Hasta hace poco este tipo de análisis no se había aplicado en nuestra tierra. Sin embargo, desde hace unos años el Este de la Península Ibérica se está convirtiendo en uno de los lugares del Mediterráneo donde se está realizando un mayor número de este tipo de estudios. Este artículo explica el potencial de los análisis isotópicos de carbono y nitrógeno sobre colágeno óseo para reconstruir las pautas alimentarias de poblaciones pasadas. También repasa todos los estudios publicados en tierras valencianas de cronología prehistórica publicados hasta la fecha,…
