The lack of balance in the Spanish First Division football league
2014
Research question: The importance of balance in sports competitions has been made evident on many occasions. The dominance of a few teams over the rest of the participants in the Spanish First Division Football League has made the subject of a lack of balance an omnipresent one in sports journalism. The aim of this article is to show that the lack of balance is not just a matter of the past few seasons, but also it has been evidenced since far back in time. To test this hypothesis, the results of the league have been analyzed since its inception through various static and dynamic indices of competitive balance.Research methods: The empirical distribution of static and dynamic indices under …
Effects of nitrogen enrichment on zooplankton biomass and N:P recycling ratios across a DOC gradient in northern-latitude lakes
2021
AbstractWe used data from whole-lake studies to assess how changes in food quantity (phytoplankton biomass) and quality (phytoplankton community composition, seston C:P and N:P) with N fertilization affect zooplankton biomass, community composition and C:N:P stoichiometry, and their N:P recycling ratio along a gradient in lake DOC concentrations. We found that despite major differences in phytoplankton biomass with DOC (unimodal distributions, especially with N fertilization), no major differences in zooplankton biomass were detectable. Instead, phytoplankton to zooplankton biomass ratios were high, especially at intermediate DOC and after N fertilization, implying low trophic transfer effi…
Individual and combined effects of disturbance and N addition on understorey vegetation in a subarctic mountain birch forest
2011
Questions: What are the effects of repeated disturbance and N-fertilization on plant community structure in a mountain birch forest? What is the role of enhanced nutrient availability in recovery of understorey vegetation after repeated disturbance? How are responses of soil micro-organisms to disturbance and N-fertilization reflected in nutrient allocation patterns and recovery of understorey vegetation after disturbance? Location: Subarctic mountain birch forest, Finland. Methods: We conducted a fully factorial experiment with annual treatments of disturbance (two levels) and N-fertilization (four levels) during 1998‐2002. We monitored treatment effects on above-ground plant biomass, plan…
Improved growth performance in rainbow trout Oncorhynchus mykiss reared at high densities is linked to increased energy retention
2015
Abstract Behaviour has been suggested as an underlying factor influencing how rearing density affects growth performance in Salmonid fishes. At low densities there is an elevated intensity of aggressive interactions and the formation of dominance hierarchies. As density increases, it is commonly assumed that aggression decreases, as the cost and effort required to establish and maintain dominance hierarchies increase. The increased energy expenditure associated with aggressive interactions has been identified as one mechanism causing a reduced efficiency in feed utilisation and therefore decreased growth performance. Manipulating aggressive behaviour through density may have advantages from…
The German Expellee Organizations: Unity, Division, and Function
2016
In the early twenty-first century, the German expellee organizations (Vertriebenenverbände) are typically portrayed as a united entity, at least in the wider public realm. The dominance of the umbrella group Bund der Vertriebenen (BdV) tends to foster the perception that the German expellee lobby is a homogeneous and cohesive bloc, focused on promoting shared political goals. This has been evident, for instance, in the media coverage of the prolonged controversy about the proposed establishment of a Center Against Expulsions in Berlin, in which the BdV’s statements have generally been taken to represent the expellee movement as a whole.1 But how correct is that interpretation, particularly …
Does the ideal entrepreneurial team exist?
2021
Up until now, studies on entrepreneurs and their relationship to business performance have focused primarily on analyzing the entrepreneur as an individual. While studies have been conducted on the entrepreneurial team, their focus has centered on team size and degree of diversity - cultural, age, gender - leaving a gap in the analysis of the effect of a team’s competencies on the outcome of the ventures. This research aims to help fill this gap by using the psychometric instrument DISC. This research analyzes entrepreneurship by opportunity, evaluating the performance of 109 Colombian companies and the composition of their entrepreneurial teams. The results obtained provide the basis for b…
Iron enrichment from hypoxic hypolimnion supports the blooming of Raphidiopsis raciborskii in a tropical reservoir.
2022
Occurring worldwide, blooms of Raphidiopsis raciborskii threaten the use of water resources especially in tropical and subtropical waterbodies. Its high flexibility in the uses of light and macronutrients (C, N, P) frustrates any bloom prediction and control based on macronutrients regulation. To identify the critical factors promoting periodic blooms of R. raciborskii, the trends of meteorological, hydrodynamic, physical, and chemical variables (including macro- and micronutrients: N, P, Fe) were analyzed in a Chinese tropical large reservoir (Dashahe reservoir) over five years. It was hypothesized that Fe availability, mediated by the mixing pattern of the reservoir, played a crucial role…
Ethnic and Religious Conflicts in France
2011
International audience; This chapter presents a detailed analysis of current and historical interethnic relations in France. Kamiejski, De Oliveira, and Guimond apply several theories in exploration of the variables related to the development of the existent ethnic tensions in this region. Policy models are also evaluated and considered as means of engendering harmony in the future. Discussion of the most recent and largest immigrant group to France, the Maghrebians, reveals several factors associated with increasing tensions including the large degree of assumed difference in values, religion, and culture. The authors recognize that France has set the stage for positive interethnic relatio…
User acceptance of automated public transport
2020
Abstract Autonomous driving is receiving increasing attention in the automotive industry as well as in public transport. However, it is still unclear whether users are willing to use automated public transportation at all. In order to answer this and other questions, the transport company of the city of Mainz, Germany, tested the autonomous minibus EMMA (Elektro-Mobilitat Mainz Autonom) on a 600-meter-long test track in public space. The study presented here was conducted with the aim of exploring crucial determinants for the use of an autonomous minibus. On the basis of established acceptance models, a questionnaire was developed, which was completed in a field survey by a total of 942 par…
Korelācija starp acu dominanci un ķermeņa stājas līdzsvaru
2017
Bakalaura darbs ir uzrakstīts angļu valodā uz 34 lapaspusēm, tas satur 21 zīmējumus, 21 atsauces uz literatūras avotiem. Darba mērķis ir novērtēt sensorialās un motorās dominances ietekmi uz ķermeņa līdzsvaru statiskos apstākļos. Salīdzinot abu atvērto acu testus ar aiztaisīto acu testiem var redzēt stipru binokulārās redzes ietekmi uz ķermeņa līdzsvaru. Turpretī nav novērota statistiska atšķirība starp atvērtas dominantās acs ietekmi un atvērtas nedominantās acs ietekmi. Visiem pētījumu dalībniekiem atvērta dominantā acs neuzrādīja lielāku ietekmi uz līdzsvara balansu kā nedominantā acs. Turpretī binokulārās redzes apstākļos līdzsvars uzlabojās, ko var redzēt pēc ticamības elipses lieluma …
