Comparing qualitative and quantitative text analysis methods in combination with document-based social network analysis to understand policy networks
Full text linkThe literature that reflects on the application of Social Network Analysis (SNA) in combination with other methods is flourishing. However, there is a dearth of studies that compare qualitative and quantitative methods to complement structural SNA. This article addresses this gap by systematically discussing the advantages and disadvantages relating to the use of qualitative text analysis and interviewing as well as quantitative text mining and Natural Language Processing (NLP) techniques such as word frequency analysis, cluster analysis, topic modeling, and topic classification to understand policy networks. This method-oriented comparative study features two empirical studies that respectively examine the Employment Thematic Network, established under the aegis of the European Commission, and the intergovernmental cooperation network set up within the Bologna Process. The article compares and discusses the underlying research processes in terms of time, human resources, research resources, unobtrusiveness, and effectiveness toward the goal of telling meaningful stories about the examined networks in light of specific guiding hypotheses. In doing so, the paper nurtures the debate on mixed-methods research on social networks amidst the well-known paradigm war between qualitative and quantitative methods in network analysis

Modelling of circulating fluidized bed combustion of a char
No full textThe combustion of a char in the 41 mm ID riser of a laboratory circulating fluidized bed combustor has been investigated at different air excesses and rates of solids (char and sand) circulating in the loop. Riser performance was characterized by an axial oxygen concentration profile as well as by the overall carbon content and particle size distribution. The proposed model accounts for carbon surface reaction, intraparticle and external diffusion, and attrition. External diffusion effects were relevant in the riser dense region where char was potentially entrapped in large clusters of inert solids. Experimental data and results of the model calculations are in satisfactory agreement. Copyright © 1991 Canadian Society for Chemical Engineerin
Comitati scientifici e COVID-19: una mappatura del policy advice in Italia
No full textThis article investigates policy advice in the case of the Italian response to the COVID- 19 pandemic. Drawing from the extensive literature on evidence-based policy-making and policy advice, we explore the nature of the latter in relation to two main themes: 1) the actors providing advice (who question), and 2) the type of advice provided (what question). The article presents empirical evidence regarding the institutional architecture and functions of scientific committees established at the central level of government and in all Italian regions. In particular, we focus on two dimensions of regional policy advice: the origin of committee members (internal or external to the regional government) and the type of expertise they possess. The evidence indicates a wide variety of configurations in terms of actors, types, and utilization of advice, with members of scientific committees performing functions ranging from management and coordination to the provision of advice in the stricto sensu
Exploring the link between administrative styles and policy output: The case of the Italian Extraordinary Commissioner for the Covid‐19 Emergency
Full text linkAdministrative style is a central concept in public policy and administration research. Despite the developments in the field, less is known about the effect different administrative styles have on policy output. To contribute to filling this gap, the article offers an original framework to explore the link between administrative styles and policy output based on the consolidated distinction between functional and positional orientations as constitutive elements of administrative styles. This framework is applied to an under-investigated case of public organisation in the Italian context, i.e. the administrative apparatus headed by the Extraordinary Commissioner for the Covid-19 Emergency, to test the general hypothesis that what makes the difference in determining output performance is an administration’s positional orientation, not only its functional one. Doing so, the article contributes to “second generation” administrative style research and provides a theoretical and analytical framework to be tested in future cross-national and cross-sectoral comparisons
Can Teachers’ Discretion Enhance the Role of Professionalism in Times of Crisis? A Comparative Policy Analysis of Distance Teaching in Italy and Switzerland during the COVID-19 Pandemic
No full textThe COVID-19 pandemic has drastically changed education with the replacement of in-school teaching with online teaching in both Italy and Switzerland. The article carries out a qualitative comparative analysis of distance teaching policy documents and shows that the considerable discretion with which teachers were left increased their need to leverage skills, experience, and public interest orientation to tackle a crisis. The analysis also shows that the availability of resources can play a key role in stimulating teachers’ professionalization. Most importantly, all these features are identified in both countries, regardless of the institutional differences between them.Note: In the interests of space, street-level theory and the pandemic context underpinning the articles for this special issue are discussed in detail in the Introduction to the issue
Sensitivity Analysis of a Circulating Fluidized Bed Combustor
No full textSensitivity analysis has been carried out on the basis of a mathematical model of a circulating fluidized bed combustor. Output variables chosen to characterize the performance of the riser of the CFB loop are carbon mass fraction, oxygen concentration profiles and carbon particle size distribution. Dominant input variables have been outlined. They include activation energy, bed temperature, overall char porosity, reaction order and char feed size distribution
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
