Once a journalist, not always a journalist? Causes and consequences of job changes from journalism to public relations
2019
Increasingly, journalists do not find permanent jobs and seek work in related fields, often in public relations. However, the two professions differ with regard to some of their normative functions: whereas journalists should report objectively and without bias, public relations practitioners are supposed to represent their clients’ particular interests. Hence, shifts from journalism to public relations have the potential for conflict. This study analyzes whether these shifts cause inter-role conflict and examines the reasons for the job changes. We conducted 17 qualitative semi-structured interviews with former journalists from Germany who have permanently transitioned into public relatio…
Evaluación de los aspectos formales de las revistas pediátricas españolas
2007
Introducción: La normalización de las revistas científicas es impresscindible para la transmisión correcta del conocimiento, pues garantiza la universalidad y reproducibilidad de las investigaciones. El objetivo de este trabajo es realizar una evaluación de los aspectos formales de las revistas pediátricas españolas. Material y métodos: En el año 2005 se estudiaron las características formales de las revistas pediátricas españolas, en particular, y de las revistas biomédicas españolas, en general. Se implementó un formulario, utilizado para la selección de las revistas que forman parte de la cobertura de la base de datos del Índice Médico Español (IME), que evaluaba 64 características difer…
Assessment of the SMAP Level-4 Surface and Root-Zone Soil Moisture Product Using In Situ Measurements
2017
International audience; The Soil Moisture Active Passive (SMAP) mission Level-4 Surface and Root-Zone Soil Moisture (L4_SM) data product is generated by assimilating SMAP L-band brightness temperature observations into the NASA Catchment land surface model. The L4_SM product is available from 31 March 2015 to present (within 3 days from real time) and provides 3-hourly, global, 9-km resolution estimates of surface (0-5 cm) and root-zone (0-100 cm) soil moisture and land surface conditions. This study presents an overview of the L4_SM algorithm, validation approach, and product assessment versus in situ measurements. Core validation sites provide spatially averaged surface (root zone) soil m…
Hyperspectral response of agronomic variables to background optical variability: Results of a numerical experiment
2022
Understanding how biophysical and biochemical variables contribute to the spectral characteristics of vegetation canopies is critical for their monitoring. Quantifying these contributions, however, remains difficult due to extraneous factors such as the spectral variability of canopy background materials, including soil/crop-residue moisture, soil-type, and non-photosynthetic vegetation (NPV). This study focused on exploring the spectral response of two important agronomic variables (1) leaf chlorophyll content (Cab ) and (2) leaf area index (LAI) under various canopy backgrounds through a global sensitivity analysis of wheat-like canopy spectra simulated using the physically-based PROSAIL …
Accelerated Changes of Environmental Conditions on the Tibetan Plateau Caused by Climate Change
2011
Abstract Variations of land surface parameters over the Tibetan Plateau have great importance on local energy and water cycles, the Asian monsoon, and climate change studies. In this paper, the NOAA/NASA Pathfinder Advanced Very High Resolution Radiometer (AVHRR) Land (PAL) dataset is used to retrieve the land surface temperature (LST), the normalized difference vegetation index (NDVI), and albedo, from 1982 to 2000. Simultaneously, meteorological parameters and land surface heat fluxes are acquired from the 40-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) dataset and the Global Land Data Assimilation System (GLDAS), respectively. Results show that from …
Teaching Green Analytical Chemistry on the Example of Bioindication and Biomonitoring (B & B) Technologies
2019
Teaching of Green Analytical Chemistry (GAC) requires a not inconsiderable willingness on the part of the lecturer to familiarize himself with a relatively new field in analytical chemistry. Although there is much that can be derived from Green and Sustainable Chemistry, the GAC’s forward-looking perspectives in particular are independent approaches that must not be neglected. In the first chapter of this article, approaches are pursued “how (teachers) learn to learn,” ultimately based on a consensus on ethics, which allows dealing with people, society and the environment to become an interdisciplinary unit. The end of all this is a smart method of conflict management which provides solutio…
Linkages Between Gameplay Preferences and Fondness for Game Music
2021
In this paper we explore connections between players’ preferences in gameplay and their desire to listen to game music. Music always takes place in cultural contexts and the activity of music listening is likewise entangled with versatile cultural practices. This is arguably evident in the case of game music since the primary context of encountering it is the active and participatory experience of gameplay. By analyzing survey data (N = 403) collected from the UK, we investigate how contextual preferences in gameplay activities predict fondness for game music. It was found that player preference for Aggression and Exploration are two precedents for liking game music. These findings indicate…
Diffusion of Drone Journalism: the Case of Finland, 2011-2020
2020
This article details Finnish news organizations’ adoption of drones for journalistic purposes from 2011 to 2020. The theoretical starting point of the article is Rogers’ (1962) diffusion of innovations theory, which explains how new ideas and technologies spread in societies. The main empirical data for the study were derived from a phone survey conducted among the 80 most popular newspapers in Finland. The findings reveal that drone journalism in Finland has already diffused from a few pioneering organizations to a large number of newsrooms, including regional, mid-sized newspapers. Most of the newspapers are either using in-house drones, buying commissioned images, or using both strategie…
Macroeconomic fluctuations and educational inequalities in suicide mortality among working-age men in the Baltic countries and Finland in 2000–2015: …
2020
Abstract Introduction In the 2000s, the Baltic countries experienced unprecedented economic growth followed by a deep recession. This study aimed to examine changes and educational inequalities in suicide mortality among working-age men in the Baltic countries and Finland in relation to macroeconomic fluctuations. Methods We analysed changes in overall suicide mortality and by educational level between the 2000–2003, 2004–2007, 2008–2011 and 2012–2015 periods among men aged 30–64 years using census-linked longitudinal mortality data. We estimated age-standardised mortality rates, mortality rate ratios (Poisson regression), the relative index of inequality and slope index of inequality. Resu…
La banlieue du "20 heures". Ethnographie de la production d'un lieu commun journalistique
2013
International audience; Plongés dans un collectif de travail régi par des logiques économiques (audience, productivité), le poids des sources légitimes et des modèles professionnels importés de l’audiovisuel commercial, les journalistes de France 2 fabriquent et perpétuent les lieux communs sur les habitants des quartiers populaires pour satisfaire dans l’urgence la commande de reportages prédéfinis par leur hiérarchie. À partir d’une enquête menée au plus près des pratiques quotidiennes des journalistes, ce livre propose une explication sociologique à la permanence des représentations réductrices véhiculées par certains contenus médiatiques.
