Hierarchical ktjet clustering for parallel architectures
Authors: Forster Richárd , Fülöp Ágnes 
Published: January 2018

AbstractThe reconstruction and analyze of measured data play important role in the research of high energy particle physics. This leads to new results in both experimental and theoretical physics. This requires algorithm improvements and high computer capacity. Clustering algorithm makes it possible to get to know the jet structure more accurately. More granular parallelization of the kt cluster algorithms was explored by combining it with the hierarchical clustering methods used in network evaluations. The kt method allows to know the development of particles due to the collision of high-energy nucleus-nucleus. The hierarchical clustering algorithms works on graphs, so the particle information used by the standard kt algorithm was first transformed into an appropriate graph, representing the network of particles. Testing was done using data samples from the Alice offine library, which contains the required modules to simulate the ALICE detector that is a dedicated Pb-Pb detector. The proposed algorithm was compared to the FastJet toolkit's standard longitudinal invariant kt implementation. Parallelizing the standard non-optimized version of this algorithm utilizing the available CPU architecture proved to be 1:6 times faster, than the standard implementation, while the proposed solution in this paper was able to achieve a 12 times faster computing performance, also being scalable enough to efficiently run on GPUs.
On metrics on 2-orbifolds all of whose geodesics are closed
Authors: Lange Christian 
Published: January 2018

Abstract
We show that the periods and the topology of the space of closed geodesics on a Riemannian 2-orbifold all of whose geodesics are closed depend, up to scaling, only on the orbifold topology and compute it. In the manifold case we recover the fact proved by Gromoll, Grove and Pries that all prime geodesics have the same length, without referring to the existence of simple geodesics. We partly strengthen our result in terms of conjugacy of contact forms and explain how to deduce rigidity on the projective plane based on a systolic inequality due to Pu.
Ancient Coppice Woodlands in the Landscape of the Czech Republic
Authors: Buček Antonín , Černušáková Linda , Friedl Michal , Machala Martin , Maděra Petr 
Published: January 2018

Abstract
Ancient coppice woodlands are forest stands of coppice origin with a long-term continual development and preserved typical natural and historic elements of old coppices. Significant natural elements in ancient coppices include polycormons of coppice shoots, pollard trees, trees with holes, dendrotelms, reserved trees, ecotones, glades and significant plant and animal species. Significant historic elements of localities with ancient coppices include archaeological monuments, boundary ditches and walls, boundary stones, boundary trees, myths and legends, sacral objects, old roads and paths, technical objects and plough land remainders. The paper presents differentiation of assumptions for the occurrence of ancient coppices in the territory of the Czech Republic using the COPF coefficient and examples of results from basic regional inventory (Kuřim region) and detailed local survey (locality Lebeďák) of coppice-originated forests. The extinction of the phenomenon of ancient coppice woodlands would mean irreparable impoverishment of the natural and cultural heritage.
Ecological Farming in Slovakia and Its Regional Disparities
Authors: Némethová Jana , Dubcová Alena , Nagyová Ľudmila , Kramáreková Hilda 
Published: January 2018

Abstract
The paper points at the origin and development of ecological farming in Slovakia from 1991 to 2015. As the positive aspect of this period can be considered the increasing area of ecologically farmed agricultural land, as well as increasing number of farmers and a slight increase in the number of processors of ecological production. The increased interest of farmers in ecological farming on land occurred mainly after Slovakia's accession to the EU. The next part of the paper is dedicated to the regional disparities in ecological production at NUTS III (Slovak regions). To analyze spatial disparities at the regional level, we used the most widely applied statistical methods - standard deviation and coefficient of variation. The largest localization of ecological production is in northern Slovakia - in Žilina and Prešov region, in central Slovakia in Banská Bystrica region. In these regions, there are higher acreage of ecological farmland. Despite the slight increase of processors of ecological produce, they still lack in Slovakia. Processors of ecological products operate mainly in the regions of western and eastern Slovakia and north of the country. With the lack of ecological production, there is relatively underdeveloped distribution of products of ecological production and its lower consumption in the domestic market. Offers of bio-products is relatively low and weak competitive environment does not create the pressure to still reduce still high prices of ecological production.
Where Have All the Youngsters Gone? The Background and Consequences of Young Adults’ Outmigration from Hungarian Small Towns
Authors: Makkai Bernadett , Máté Éva , Pirisi Gábor , Trócsányi András 
Published: January 2018

Abstract
Due to the general demographic situation in Hungary and the recent overall crisis of this traditional settlement-type, Hungarian small towns have been facing an intensive shrinking since the last decade. Although natural decrease and migration loss are almost equal factors of population decline, outmigration seems to be a more strategic, critical problem for these settlements. There are hardly any reliable data available about the migrants leaving small towns, but some of them seem to support the wellknown assumption that the young people, who leave these towns are looking for wider horizons and better perspectives. The aim of the present paper is to analyse the outmigration of young adults from small towns, and give estimation about the international aspects of migration, which is hardly ever published in official statistics. The paper also aims at revealing the impact of the intensive migration on the local labour market. A short statistical analysis based on census data and two empirical surveys conducted by the authors are also included. One was carried out with the support of volunteer contributors, former small-town students, who tried to reconstruct the post-secondary school migration of their former classmates. The other survey contains a series of interviews focusing on the consequences of the young adults’ migration on the labour market. The results facilitate the estimation regarding the (weak) capability of small towns to keep their young population, and highlight the problems of local developmental options within the context of demographic shrinkage.
Women as Drivers for a Sustainable and Social Inclusive Development in Mountain Regions – The Case of the Austrian Alps
Authors: Oedl-Wieser Theresia 
Published: January 2018

Abstract
Women in mountain regions play an important role regarding the agricultural production and ensuring sustainable livelihoods. Furthermore, they are active in climate change adaption and preservation of biodiversity. Despite these important activities and performances the vital role of women for a sustainable and social inclusive development in mountain regions is often invisible and not appreciated enough in society. There still exists structural discrimination of women which is caused by patriarchal societies, social and cultural norms as well as difficult economic situations. Considering the need to foster the dynamic and sustainable development of mountain regions all over the world, it is of paramount importance to reflect and integrate women’s issues, problems and needs to a larger extent in research, public policy and in worldwide decision-making agendas.
Teacher Learning for European Literacy Education (TeL4ELE): genre-based pedagogy in five European countries
Authors: Whittaker Rachel , García Parejo Isabel 
Published: January 2018

AbstractThis article gives two perspectives on an action-research literacy project based on the pedagogy of Reading to Learn (R2L). The project, organized in a cascade structure, introduced the functional linguistics-based pedagogy for reading and writing across the curriculum to national teams of key educators, who then took it to practising teachers, who used it with their pupils. The impact of the project on the three groups of 'learners' involved was then evaluated through questionnaires for educators and teachers and reading and writing tests. Knowledge of the texts of their subjects, and of the R2L interaction cycle, changed participants' practice, resulting in student inclusion and improved written production. The paper first presents a broad view of the project and results in its European context, and, second, a more detailed picture of one of the countries involved, Spain, including examples of implementation by participating teachers, their responses to the pedagogy, and student up-take in samples of their texts. The paper closes with reflections and future directions the project is taking in Spain, opening to new contexts for the R2L pedagogy.
Upper bounds for geodesic periods over rank one locally symmetric spaces
Authors: Frahm Jan , Su Feng 
Published: January 2018

Abstract
We prove upper bounds for geodesic periods of automorphic forms over general rank one locally symmetric spaces. Such periods are integrals of automorphic forms restricted to special totally geodesic cycles of the ambient manifold and twisted with automorphic forms on the cycles. The upper bounds are in terms of the Laplace eigenvalues of the two automorphic forms, and they generalize previous results for real hyperbolic manifolds to the context of all rank one locally symmetric spaces.
Promoting physical activity and improving dietary quality of Singaporean adolescents: effectiveness of a school-based fitness and wellness program

Published: January 2018

Abstract
Limited data are available on the effectiveness of the school-based structured fitness and wellness program to influence dietary quality and physical activity levels in Singaporean adolescents. The study examined if a 20-h (over 10 weeks) school-based structured fitness and wellness module affects the diet quality indices, energy intakes, physical activity levels and the associated energy expenditures in a group of healthy, male adolescents with low diet quality and physical activity levels. Participant demography, anthropometry, dietary intake and daily physical activity were obtained at the beginning, mid-point and end of the 10-week program. Physical activity levels were assessed accelerometrically over a 1-weekday period. Dietary intake were taken using a structured 7-day food diary, and diet quality assessed using the Diet Quality Index-International (DQI-I). The 31 enrolled participants (age 19.8 ± 0.6 years) with body mass index (BMI) (19.8 ± 0.6 kg/m2) followed diets of low diet quality scores (48.3 ± 9.6 out of 100) and engaged in 3.87 ± 2.00 h of physical activity daily before the start of the intervention. Their dietary quality and physical activity levels did not change significantly throughout the intervention period. They scored poorly in the moderation and overall balance components of the diet quality assessment. The physical activity duration correlated inversely to the diet quality scores. Our results suggest that the prescribed school-based fitness and wellness module was ineffective in influencing the diet quality and physical activity levels of Singaporean male adolescents with low diet quality and physical activity levels.
Blunted cortisol reactivity and risky driving in young offenders – a pilot study
Authors: Couture Sophie , Ouimet Marie Claude , Dedovic Katarina , Laurier Catherine , Plusquellec Pierrich , Brown Thomas G. 
Published: January 2018

AbstractAdolescent risky driving is a significant burden on public health. Young offenders (i.e. under custody and supervision of the criminal justice system) may be particularly vulnerable, but research is scant. Previous work indicated that blunted cortisol reactivity to stress is a marker of risk-taking predisposition, including risky driving. In this study, we hypothesized that young offenders display higher levels of risky driving than a non-offender comparison group, and that cortisol reactivity contributes to the variance in risky driving independent of other associated characteristics (i.e. impulsivity, risk taking, alcohol and drug use). We found that young offenders (n = 20) showed riskier driving in simulation than comparison group (n = 9), and blunted cortisol reactivity was significantly associated with risky driving. The results suggest young offenders are prone to risky driving, and that individual differences in the cortisol stress response may be an explanatory factor.
Prevalence, associated factors, and control level of asthma symptoms among adolescents in Northern Jordan
Authors: Al-sheyab Nihaya A. , Alomari Mahmoud A. 
Published: January 2018

Abstract

Objective
To investigate the prevalence, associated factors, and control level of asthma in Jordanian high school students.

Methods
A descriptive, comparative, cross sectional design was used and a cluster sample of 2691 students (mean age = 14.5 years, 51.0% girls), drawn from eight randomly selected public high schools in Northern Jordan, participated in the study. Each student had the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire completed in the classroom between February and May, 2015.

Results
The prevalence of recent wheezing in the last 12 months was 11.7% whereas the prevalence of diagnosed asthma was 6.2%. About 49% of students experienced cough all the time, and 33.5% experienced waking up at night due to wheezing some of the time. About 30.9% of students reported moderate to big exercise-induced asthma. The mean total Asthma Control Test (ACT) score was 5.85 (SD = 3.56) with all of students reporting uncontrolled asthma during the last month. Higher rates of asthma symptoms were reported by females, 10th graders, and students with negative family history. Importantly, students with diagnosed asthma or recent wheezing reported higher rates of ever smoking tobacco vs. non-asthmatics (p < 0.000); dual (18.6% vs. 9.8%), cigarettes only (11.2% vs. 7.3%), and waterpipe only (18.0% vs. 14.7%).

Conclusion
Overall, students with asthma or wheezing had increased rates of tobacco smoking. Policies need to be set and enforced to provide a better environment for these youth, especially making all schools smoke-free zones. A multifaceted, comprehensive awareness and management program is required in schools to control and manage asthma symptoms.

Published: January 2018

Abstract
In order to study the effect of corn kernel composition and physical structure on moisture distribution and transfer process and obtain the optimal tempering-drying parameters of corn kernel, a physical model was constructed with four different components as follows: seed coat, horny endosperm, farinaceous endosperm and embryo. The drying model was established based on the assumption of different diffusion coefficients and same thermal conductivity for the four components. The software of COMSOL Multiphysics was used to simulate the heat and mass transfer process inside the corn kernel during the thin-layer drying. The results showed that the least total drying time and the best drying quality were achieved under the multistage circulating drying of 10 min hot air drying and 60 min tempering, and the tempering degree was up to 0.9207.
“Too many Americans are trapped in fear, violence and poverty”: a psychology-informed sentiment analysis of campaign speeches from the 2016 US Presidential Election
Authors: Hoffmann Thomas 
Published: January 2018

Abstract
Most automatic sentiment analyses of texts tend to only employ a simple positive-negative polarity to classify emotions. In this paper, I illustrate a more fine-grained automatic sentiment analysis [Jockers, Matthew. 2016. Introduction to the Syuzhet package. https://cran.r-project.org/web/packages/syuzhet/vignettes/syuzhet-vignette.html (accessed 07 March 2017).; Mohammad, Saif M. & Peter D. Turney. 2013. Crowd sourcing a word-emotion association lexicon. Computational Intelligence 29(3). 436–465.] that is based on a classification of human emotions that has been put forward by psychological research [Plutchik, Robert. 1994. The psychology and biology of emotion. New York, NY: HarperCollins College Publishers.]. The advantages of this approach are illustrated by a sample study that analyses the emotional sentiment of the campaign speeches of the two main candidates of the 2016 US presidential election.
Der Einfluss von Fortbewegung auf die sensorische Informationsverarbeitung und die zugrunde liegenden neuronalen Schaltkreise
Authors: Busse Laura 
Published: January 2018

Zusammenfassung
Die Verarbeitung sensorischer Information kann sowohl im Kortex als auch im Thalamus durch den Verhaltenskontext, z. B. durch aktive Fortbewegung, moduliert werden. Solch aktives Verhalten verbessert die Kodierung sensorischer Reize und die Wahrnehmung, besonders während Aktivitäten von moderater Intensität. Der Modulation sensorischer Verarbeitung durch Fortbewegung scheint eine Kombination von Mechanismen zugrunde zu liegen, unter anderem neuromodulatorische Einflüsse, die Aktivität spezifischer, inhibitorischer Interneurone, sowie top-down- oder motorische Rückprojektionen. Neue experimentelle Ansätze, die es Mäusen erlauben, sich trotz Kopffixation auf Laufbällen oder –bändern fortzubewegen, ermöglichte es in den letzten Jahren, die neuronalen Schaltkreise und zellulären Elemente, die der Modulation durch Verhaltenskontext zugrunde liegen, eingehend zu untersuchen. Dieser Übersichtsartikel fasst den momentanen Stand dieser Studien zusammen und beleuchtet wichtige offenen Fragen.
Dissemination of Environmental Information and its Effects on Stakeholders’ Decision-Making: A Comparative Study between Swedish and Polish Municipalities
Authors: Cregård Anna , Sobis Iwona 
Published: January 2018

AbstractAccording to Action Agenda 21, which was adopted at the Rio Conference in 1992, sustainable development is a major objective for local and global development. Economic growth, good living conditions, and protection of the earth’s natural environment are important to all people in the world. This article focuses on one aspect of sustainable development, i.e. on environmental sustainability. Research shows that local government can take a leading position in protecting the natural environment and disseminating information on it among stakeholders. However, our knowledge about the dissemination of environmental information practices among stakeholders is limited. The purpose of this research is to fill a gap in current knowledge, to describe and compare the practical work with dissemination of such information among stakeholders in Swedish and Polish municipalities. The questions to be answered are: What environmental information is collected and produced by the local government ? At what stakeholders is such information targeted ? and What effects does it have on decision-making by stakeholders in the investigated municipalities ? The study is based on state regulations, the homepages of municipal offices, and policy documents, official reports, and semi-structured interviews with key managers responsible for the protection of the natural environment in the studied municipalities. Data were collected from late 2015 to early 2017. This research indicates that dissemination of environmental information has a positive effect on the decision-making of internal stakeholders. In both countries, the municipal authorities follow the EU recommendations, resulting in innovative work and growing environmental awareness among the municipal authorities, the residents, and other stakeholders. Improvement of the natural environment is perceived as “a must” for the future. Nonetheless, especially larger municipalities face challenges because the production and dissemination of environmental information is time-consuming. In the long run, however, surprisingly positive effects on the local protection of the natural environment appear.
Innovative Administrative Procedure Law: Mission Impossible ?
Authors: Kovač Polonca 
Published: January 2018

Abstract
Law and innovation are oft en seen as antagonistic notions, particularly in administrative (authoritative) relations. Th is paper addresses this issue based on the regulation of administrative procedures, since they represent core public-administration activities in contemporary society. Hence, they need to be codified and implemented, both on the EU and national levels, in a more flexible and party-oriented way, even though still preserving legal certainty. The author argues that Europeanisation contributes to innovation in administrative procedure law, with institutions such as alternative dispute resolution or one-stop-shops. In order to explore the potential drivers of and barriers to innovation, particularly in Eastern Europe, a survey and several structured interviews were carried out in Slovenia as a case study. Th e results reveal that the culture in the region is legalistically driven and thus hinders innovation, even that which has already been introduced in the law. Consequently, a key obstacle to be addressed in future measures is the mind-set in public administration rather than a pure legal change.
Negative Effects of Performance Based Funding of Universities: The Case of Slovakia
Authors: Pisár Peter , Šipikal Miroslav 
Published: January 2018

AbstractAlthough it is well-known that public-funded research has contributed to economic development, even these days it is not clear how to support this research effectively. Tailoring the proper support system still remains a challenge for the government. Th is is also the case for research support for universities, which are one of the main “engines” of public-funded research. One possible answer is performance-based funding. Th is funding has recently come to be increasingly used by many countries. However, performance-based funding may have several inconveniences. Th is article will analyze the performance-based funding that has already been introduced in the Slovak Republic. Our research outcomes prove the fact that this system has resulted in an increase in publication performance, but at the same time in a higher orientation on quantity instead of quality with several new negative effects.
