Empirical Evaluation of a Differentiated Assessment of Data Structures: The Role of Prerequisite Skills
There can be many reasons why students fail to answer correctly to summative tests in advanced computer science courses: often the cause is a lack of prerequisites or misconceptions about topics presented in previous courses. One of the ITiCSE 2020 working groups investigated the possibility of designing assessments suitable for differentiating between fragilities in prerequisites (in particular, knowledge and skills related to introductory programming courses) and advanced topics. This paper reports on an empirical evaluation of an instrument focusing on data structures, among those proposed by the ITiCSE working group. The evaluation aimed at understanding what fragile knowledge and skills the instrument is actually able to detect and to what extent it is able to differentiate them. Our results support that the instrument is able to distinguish between some specific fragilities (e.g., value vs. reference semantics), but not all of those claimed in the original report. In addition, our findings highlight the role of relevant skills at a level between prerequisite and advanced skills, such as program comprehension and reasoning about constraints. We also suggest ways to improve the questions in the instrument, both by improving the distractors of the multiple choice questions, and by slightly changing the content or phrasing of the questions. We argue that these improvements will increase the effectiveness of the instrument in assessing prerequisites as a whole, but also to pinpoint specific fragilities
The Effects of Media and their Logic on Legitimacy Sources within Local Governance Networks: A Three-Case Comparative Study
__Abstract__
Although theoretical and empirical work on the democratic legitimacy of
governance networks is growing, little attention has been paid to the impact of mediatisation
on democracies. Media have their own logic of news-making led by the mediaâs rules,
aims, production routines and constraints, which affect political decision-making processes.
In this article, we specifically study how media and their logic affect three
democratic legitimacy sources of political decision-making within governance networks:
voice, due deliberation and accountability. We conducted a comparative case study of
three local governance networks using a mixed method design, combining extensive
qualitative case studies, interviews and a quantitative content analysis of media reports.
In all three cases, media logic increased voice possibilities for citizen groups.
Furthermore, it broadened the deliberation process, although this did not improve the
quality of this process per se, because the media focus on drama and negativity. Finally,
media logic often pushed political authorities into a reactive communication style as they
had to fight against negative images in the media. Proactive communication about
projects, such as public relation (PR) strategies and branding, is difficult in such a
media landscape
Trends in modeling Biomedical Complex Systems
In this paper we provide an introduction to the techniques for multi-scale complex biological systems, from the single bio-molecule to the cell, combining theoretical modeling, experiments, informatics tools and technologies suitable for biological and biomedical research, which are becoming increasingly multidisciplinary, multidimensional and information-driven. The most important concepts on mathematical modeling methodologies and statistical inference, bioinformatics and standards tools to investigate complex biomedical systems are discussed and the prominent literature useful to both the practitioner and the theoretician are presented
Populist communication in the new media environment: a cross-regional comparative perspective
The changing terms of mediation place new demands, opportunities and risks on the performance of the political persona. Visibility has become a double-edged sword, leaving representatives vulnerable to exposure while new tools provide opportunities for emerging entrepreneurial actors. This double risk to elitesâ mediated personasâexposure and challenge from entrepreneursârenders their armour of authenticity dangerously fragile, which nourishes a public sense of being inefïŹcaciously represented. It is this climate in which populism currently ïŹourishes around the globe. Three primary criteria of mediated self-representation by politiciansâvisibility, authenticity and efïŹcacyâform the focus of this paper: how do populists negotiate such demands in different democratic contexts, and wherein lies the symbiosis between populism and the new media environment suggested by the literature? To answer this, the paper compares two populist cases responding to different democratic contexts: UKIP, a right-wing party from an established democracy (UK), and the Economic Freedom Fighters (EFF), a left-wing party from a transitional democracy (South Africa). The objects of study are disruptive performances by these parties, which are considered emblematic manifestations of populist ideology as they establish a Manichaean relationship between the elite and populist actors who embody the people. The paper introduces disruption as a multi-faceted and signiïŹcant analytical concept to explain the populist behaviour and strategies that underlie populist partiesâ responses to the demands for visibility, authenticity and efïŹcacy that the new media environment places upon political representatives. Using mixed methods with an interpretive focus, the paper paints a rich picture of the contexts, meanings and means of construction of populist performances

Reinforcing Spirals at Work? : Mutual Influences between Selective News Exposure and Ideological Leaning
The growth of partisan news sources has raised concerns that people will increasingly select attitude-consistent information, which lead to increasing political polarization. Thus far, there is limited research on the long-term mutual influences between selective exposure and political attitudes. This study therefore investigates the reciprocal influences between selective exposure and political attitudes over several years, using a three-wave panel survey conducted in Sweden 2014â2016. More specifically, we analyse how ideological selective exposure to both traditional and online news media influences citizensâ ideological leaning. Findings suggest that (1) people seek-out ideologically consistent print news and online news, and (2) such attitude-consistent news exposure reinforces citizensâ ideological leaning over time. In practice, however, such reinforcement effects are hampered by (3) relatively low overall ideological selective exposure and a (4) significant degree of cross-cutting news exposure online. These findings are discussed in light of selective exposure theory and reinforcing spirals model.PLEASE NOTE: The final version of this paper was published as: â Dahlgren, Peter M., Shehata, Adam & StrömbĂ€ck, Jesper (2019).
