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…
O Śląsku i badaniach śląskoznawczych raz jeszcze
2019
The present workoffers a synthetic review of the state of studies on a broadly-understood culture of Silesia and the language of this region. The author discusses the achievements of folklorists, experts in culture studies and linguists, especially those based in Opole Region and connected with the University of Opole and the State Scientific Institute – the Silesian Institute. Attention is paid to the continuing need for carrying out Silesian studies and the necessity of searching for new methodological solutions. The text also foreruns the appearance of a series of articles included in this monograph, which are devoted to the cultural heritage of Silesia – shownfrom different perspectives…
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…
Narrativity and its application in business ethics research
2018
Purpose The purpose of this paper is to develop a narrative framework for doing empirical research into business ethics and shows, through two examples, how the framework can be applied in practice in this context. The focus is on interview-based research. Design/methodology/approach A theoretical research based on literature review was conducted. Findings In the developed narrative framework, two main kinds of analysis are distinguished: an analysis of the narrative and a narrative analysis. An analysis of the narrative is a matter of classifying and producing taxonomies out of the data. The purpose of a narrative analysis is to construct a story or stories based on the data. Narrative an…

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 …
