Priorities for research in soil ecology
2017
The ecological interactions that occur in and with soil are of consequence in many ecosystems on the planet. These interactions provide numerous essential ecosystem services, and the sustainable management of soils has attracted increasing scientific and public attention. Although soil ecology emerged as an independent field of research many decades ago, and we have gained important insights into the functioning of soils, there still are fundamental aspects that need to be better understood to ensure that the ecosystem services that soils provide are not lost and that soils can be used in a sustainable way. In this perspectives paper, we highlight some of the major knowledge gaps that shoul…
Ecological network analysis reveals the inter-connection between soil biodiversity and ecosystem function as affected by land use across Europe
2016
Soil organisms are considered drivers of soil ecosystem services (primary productivity, nutrient cycling, carbon cycling, water regulation) associated with sustainable agricultural production. Soil biodiversity was highlighted in the soil thematic strategy as a key component of soil quality. The lack of quantitative standardised data at a large scale has resulted in poor understanding of how soil biodiversity could be incorporated into legislation for the protection of soil quality. In 2011, the EcoFINDERS (FP7) project sampled 76 sites across 11 European countries, covering five biogeographical zones (Alpine, Atlantic, Boreal, Continental and Mediterranean) and three land-uses (arable, gra…
Public Administration and the Study of Political Order: Towards a Framework for Analysis
2020
The contribution of this study is two-fold: First, it outlines a conceptual framework on political order; and secondly, it offers empirical illustrations on the case of Nordic cooperation. Taken together, the article makes a plea for public administration scholarship in the study of political order. Political order consists of a relatively stable arrangement of institutions that are fairly formalized and institutionalized. A common political order, moreover, entails that relevant institutions: (i) are fairly independent of pre-existing institutions; (ii) are relatively integrated and internally cohesive; and (iii) are reasonably able to influence governance processes within other institutio…
Circolazione e sviluppo di un modello metodologico. La critica testuale delle fonti giuridiche romane fra Otto Gradenwitz e Salvatore Riccobono
2018
La ricerca delle interpolazioni, cominciata con la Scula culta, viene ripresa in Germania alla fine del XIX secolo. Fra quanti misero a punto un metodo storico-critico per lo studio delle fonti giuridiche romane va menzionato anche Gradenwitz, che – insieme ad altri studiosi tedeschi – sarebbe stato uno dei maestri di Riccobono. La prima produzione scientifica di Riccobono, che si riconosce nel nuovo indirizzo storico-critico affermatosi in Germania, si avvale dei metodi appresi dai maestri tedeschi. Lungo questo solco, tuttavia, comincia l’elaborazione di un metodo più raffinato, che distingue fra interpolazioni formali e interpolazioni sostanziali e recupera gradualmente altri strumenti d…
A View from the Inside: The Dawning Of De-Westernization of CEE Media and Communication Research?
2015
The Editorial outlines some characteristics of the development of the Central and Eastern European (CEE) media and communication scholarship during the past 25 years. In the majority of CEE countries, the media and communication research was re-established after the collapse of communism. Since then, a critical mass of active scholars has appeared who form an integral part of the larger European academia. A gradual integration of East and West perspectives in media and communication research is taking place along with moving away from the barely West-centred approach, and utilizing the research done by CEE scholars. Certain 'de-westernization' and internationalization of the research in ter…
Construct validity of the anxiety sensitivity index-3 in clinical samples
2012
"Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3). Confirmatory factor analyses established a clear three-factor structure that corresponds to the postulated subdivision of the construct into correlated somatic, social, and cognitive components. Participants with different primary clinical diagnoses differed from each other on the ASI-3 subscales in theoretically meaningful ways. Specifically, the ASI-3 successfully discriminated patients with anxiety disorders from patients with nonanxiety disorders. Moreover, patients with panic disorder or agoraphobia manifested more somatic concerns …

Graphical models for estimating dynamic networks
2012
Het bepalen van dynamische netwerken met behulp van data is een actief onderzoeksgebied, met name in de systeem biologie. Het schatten van de structuur van een netwerk heeft te maken met het bepalen van de aan of afwezigheid van een relatie tussen de hoekpunten in de graaf. Grafische modellen definiëren deze relaties via conditionele afhankelijkheid. In Gaussiaanse grafische modellen (GGM) wordt verondersteld dat de hoekpunten een normale verdeling volgen. Dit heeft grote voordelen vanwege de computationele handelbaarheid van GGM. Standaard GGM zijn echter niet bruikbaar om grote netwerken te bestuderen, i.e. als het aantal waarnemingen minder is dan het aantal hoekpunten van de graaf. Rece…
The Rocky Road towards Professional Autonomy : The Estonian Journalists’ Organization in the Political Turmoil of the 20th Century
2017
This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association,…
Localizing the politics of privacy in communication and media research
2020
While previous communication and media research has largely focused on either studying privacy as personal boundary management or made efforts to investigate the structural (legal or economic) condition of privacy, we observe an emergent body of research on the political underpinnings of privacy linking both aspects. A pronounced understanding of the politics of privacy is however lacking. In this contribution, we set out to push this forward by mapping four communication and media perspectives on the political implications of privacy. In order to do so, we recur on Barry’s (2002) distinction of the political and the politics and outline linkages between individual and structural dimensions…
