Illusion of knowledge through Facebook news? Effects of snack news in a news feed on perceived knowledge, attitude strength, and willingness for disc…
2020
Abstract Research indicates that using social network sites as a source for news increases perceived knowledge even if, objectively, people fail to acquire knowledge. This might result from the frequent repetition of topics in news posts caused by multiple news outlets posting about the same news topics and the algorithm that favors similar postings. These repeated encounters can have a positive effect on the perception of knowing more, even if actual learning hardly occurs. An experiment (N = 810, representative of German Internet users) tested these assumptions. Participants were assigned to one of four groups and received a news feed with no information, few news posts, many news posts, …
Music as a mnemonic to learn gesture sequences in normal aging and Alzheimer’s disease
2014
Strong links between music and motor functions suggest that music could represent an interesting aid for motor learning. The present study aims for the first time to test the potential of music to assist in the learning of sequences of gestures in normal and pathological aging. Participants with mild Alzheimer's disease (AD) and healthy older adults (Controls) learned sequences of meaningless gestures that were either accompanied by music or a metronome. We also manipulated the learning procedure such that participants had to imitate the gestures to-be-memorized in synchrony with the experimenter or after the experimenter during encoding. Results show different patterns of performance for t…
Fintech strategy: E-reputation
2021
Digital media use applied to professional atmosphere is increasing its relevance in the companies of the 21st century. As a consequence, organisations should bear this fact in mind and adapt their corporate strategies to the new market demands. Online social networks offer customers the possibility to bring attention to issues they believe need to be addresses by organisations. Added to this, e-reputation plays a pivotal role in determining a company's competitive advantage. This paper studies the role of e-communications in an organisation's strategy and how analytics and modelling techniques are used to take advantage of the digital media content. It discusses the historical reputational …
Consumers’ Sustainability Perceptions of the Supply Chain of Locally Produced Food
2010
This article is based on a qualitative focus group study regarding consumer perceptions about the sustainability of locally produced food supply chains. Sustainability perceptions were analyzed through thematic content analysis, where the most important economic, environmental and social themes of the supply chain were emphasized. According to the research findings, the socio-cultural aspects encompassing locally produced food form the most important sustainability dimension for consumers. Although the sample size is small, consisting of 19 consumers and limited to Central Finland, the findings suggest that the sustainability of local food should be promoted via socio-cultural arguments alo…
Inequalities and the Impact of Job Insecurity on Health Indicators in the Spanish Workforce
2020
In a context of high job insecurity resulting from social deregulation policies, this research aims to study health and substance abuse inequalities in the workplace from a gender perspective. To this end, a transversal study was carried out based on microdata from the National Health Survey in Spain&mdash
Subjective Well-Being, Emotional Intelligence, and Mood of Parents: A Model of Relationships. Impact of Giftedness
2020
The well-being of parents could be either a protective or risk factor for themselves or their children. Our objective is to analyse the affective components of subjective well-being (SWB), emotional intelligence (EI), and parental mood. Parents of gifted children may be a vulnerable group because they face exceptional challenges in raising their children, sometimes with neither educational nor social support. We assess whether parents&rsquo
Project Education and Adams’ Theory of Equity
2020
This work-in-progress paper in research category is concerned with students’ perceptions of justice in software engineering group projects. Taking a directed content analysis approach, the aim is to analyze the relevance of Adams’ theory of Equity for small-group project education. The analysis was applied to the data collected from a third-year project course in which students encounter an open-ended group assignment. The results indicate that the theory can serve as a useful framework that helps teachers to identify justice-related issues in project courses. On the other hand, it was concluded that special carefulness is advisable considering the simplicity of the theory. peerReviewed
Data from: Higher resource level promotes virulence in an environmentally transmitted bacterial fish pathogen
2017
Diseases have become a primary constraint to sustainable aquaculture, but remarkably little attention has been paid to a broad class of pathogens: the opportunists. Opportunists often persist in the environment outside the host and their pathogenic features are influenced by changes in the environment. To test how environmental nutrient levels influence virulence, we used strains of Flavobacterium columnare, an environmentally transmitted fish pathogen, to infect rainbow trout and zebra fish in two different nutrient concentrations. To separate the effects of dose and nutrients, we used three infective doses and studied the growth of bacteria in vitro. High nutrient concentration promoted b…
Data from: Grazing decreases N partitioning among coexisting plant species
2018
1. Herbivores play a key role in shaping ecosystem structure and functions by influencing plant and microbial community composition and nutrient cycling. 2. This study investigated the long-term effects of herbivores on plant resource acquisition. We explored differences in the natural δ15N signatures in plant, microbial and soil N pools, and examined mycorrhizal colonization in two tundra sites that have been either lightly or heavily grazed by reindeer for more than 50 years. The study examined changes in nutrient acquisition in five common tundra plants with contrasting traits and mycorrhiza status; the mycorrhizal dwarf shrubs, Betula nana, Vaccinium myrtillus and Empetrum hermaphroditu…
Data from: Phosphorus limitation enhances parasite impact: feedback effects at the population level
2014
Background: Nutrient deficiency affects the growth and population dynamics of consumers. Endoparasites can be seen as consumers that drain carbon (C) or energy from their host while simultaneously competing for limiting resources such as phosphorus (P). Depending on the relative demands of the host and the parasite for the limiting nutrient, intensified resource competition under nutrient limitation can either reduce the parasite?s effect on the host or further reduce the fitness of the nutrient-limited host. So far, knowledge of how nutrient limitation affects parasite performance at the host population level and how this affects the host populations is limited. Results: We followed the po…
