Conducting case study research in occupational therapy
2006
Background: Case study research has been used increasingly in psychology and sociology in recent years. It provides researchers with an opportunity to explore a situation involving one individual or several individuals over time from multiple points of view. Methods: This literature review explains case study research as a method and summerises its scientific merit, also providing an example of its use. Results: Case study research offers occupational therapists a scientific methodology that can be used to understand and develop occupational therapy practice. Conclusion: This paper argues that case study research should be used more extensively by occupational therapists as the method respe…
When Methodology Interferes With Substance
2005
For campaigners, and also attendant researchers, the advent of the Internet has challenged established ways of doing their respective campaign business. Practitioners, used to running local and media campaigns, can nowadays also resort to elements of web campaigning, while electoral researchers, used to running election studies based on personal or telephone interviews, can now employ online surveys to do their business. However, e-campaigning and online polling suffer from severe deficiencies. Based on online and offline surveys conducted in the run-up to the 2002 German election, we show two things. First, online surveys yield biased results; second, e-campaigning reaches only a tiny fra…
On the optimal design of multi-stage cascaded transistor amplifiers with noise, gain and mismatch constraints
2007
The problem of evaluating the optimal performances of cascaded, unbalanced, multi-stage transistor amplifiers is addressed. In particular, a theoretically rigorous approach is proposed for the determination of a family of Optimal Design Curves (ODC's) which express the best noise-gain tradeoff that can be achieved - at each frequency and device operating condition - when a simultaneous constraint on amplifier input VSWR is accounted for. Such curves can be used as a more meaningful starting point in practical amplifier design in place of the approximate calculations so far employed for target performance or optimization goals determination.
Optimization of ultrasound-assisted extraction of phenolic compounds from grapefruit (Citrus paradisiMacf.) leaves via D-optimal design and artificia…
2018
The extraction of phenolic compounds from grapefruit leaves assisted by ultrasound-assisted extraction (UAE) was optimized using response surface methodology (RSM) by means of D-optimal experimental design and artificial neural network (ANN). For this purpose, five numerical factors were selected: ethanol concentration (0-50%), extraction time (15-60 min), extraction temperature (25-50 °C), solid:liquid ratio (50-100 g L-1 ) and calorimetric energy density of ultrasound (0.25-0.50 kW L-1 ), whereas ultrasound probe horn diameter (13 or 19 mm) was chosen as categorical factor.; Results: The optimized experimental conditions yielded by RSM were: 10.80% for ethanol concentration; 58.52 min for…
El efecto del anuncio de beneficios cuando cotizan opciones: un estudio conjunto del mercado de contado y el mercado de opciones
2015
ResumenEl objetivo del trabajo es comprobar, para los mercados de valores españoles, si el comportamiento de los precios incorporando la información revelada por el anuncio de beneficios trimestrales, es más eficiente en aquellas empresas en las cuales se negocian opciones sobre sus acciones. Utilizando la tradicional metodología del suceso y la comparación de funciones de distribución, obtenemos que para las empresas con opciones, la información se incorpora antes. Además, verificamos que hay un comportamiento anormal en el mercado de opciones que viene explicado por la información que contiene el beneficio. Los resultados obtenidos soportan la mejora de la eficiencia del mercado de contad…

Preparing students to participate to the didactic activities of university teacher
2016
«Student Voice» è un movimento pedagogico nato negli anni Novanta nei Paesi di lingua inglese (Stati Uniti, Canada, Inghilterra e Australia): esso sostiene la partecipazione attiva e responsabile degli studenti che frequentano la scuola e l’università nella didattica dei docenti, nella ricerca universitaria e nelle politiche educative e culturali che li riguardano. Nella ricerca sperimentale qui presentata, si è voluta prestare attenzione alla partecipazione degli studenti universitari (n. 33) alle attività didattiche di un docente di pedagogia sperimentale. Si è scelto di adottare due metodi d’intervento: la scrittura espressiva, come metodo di analisi del futuro prefigurato nelle aspettat…
Discorso sul metodo di Peppa Pig
2022
This article goes through the events and the theoretical problems raised by the publication of a Semiotic essay that the author has dedicated to the analysis of Peppa Pig, a popular TV series targeted to early-childhood. Assuming a situated point of view, it chooses to dramatize the position of the researcher towards the complexity as represented by the emergence of the “wilderness” of the text to analyze. Consequently, this article aims at enlightening the strategies actually followed by the author in facing this complexity. What format and style to choose in the writing process? How to identify the limits of the text? How to evaluate the eventuality that inspired the analytical curiosity …
The usage of Twitter from the Spanish media during the elections
2018
Los medios de comunicación tradic ionales han adoptado Twitter c omo otro canal por el que difundir su información y llegar hasta las audiencias digit ales. Este estudio tiene como objetivo analizar las características de los tuits publicados por los me dios españoles durante doce meses en los que se producen dos procesos electorales, para comprobar las di ferencias en la utilización de esta plataforma según el contenido de la cobertura y la fase en que se publica. La investigación se fundamenta en una metodología cua ntitativa, en la que se implem enta un análisis de contenido computarizado de las publicacione s en Twitter que hacen los dis tintos tipos de medios entre 2015 y 2016. Los res…
Rhetoric and Pragmatics: Suggestions for a Fruitful Dialogue
2013
The aim of this paper is to show that classical rhetoric can provide valuable insights in the contemporary debate in pragmatics. This is especially true for Aristotelian rhetoric, due to its philosophical approach. In the first part of the paper, I discusses the conditions under which ancient rhetoric can be a real partner of current pragmatics: (1) rhetoric must be understood as a type of knowledge (a techne) and not as a “jumbles of techniques”; (2) we need to consider persuasion as an anthropological feature and not only as a specific case of communication; (3) we should not exclude truth from the rhetorical field. The second part of the paper focuses on what can be considered the basic …
