Design of a Cleaning Program for a PV Plant Based on Analysis of Energy Losses

2015

Solar photovoltaic (PV) energy has grown significantly over the past few years. However, despite the increase in installed capacity, this energy source still raises important concerns related to the variability of power production. The short-term effects such as cloud shadowing and supply interruptions, as well as long-term effects such as dust accumulation, seasonal variation, and ageing of PV modules, can cause variability of power production. Therefore, the analysis of all the variability sources in order to provide statistically consistent power production data is an important challenge. This study presents a methodology to analyze data from a PV plant in order to have an independent ev…

Does innovativeness reduce startup survival rates?

2015

There are two competing hypotheses explaining how innovativeness influences the survival of startups: On the one hand, innovativeness is argued to foster survival-enhancing attributes (e.g., market power and cost efficiency) and capabilities (e.g., absorptive capacity). On the other hand, an innovative startup faces (and bears the associated risks of) liabilities of newness and smallness that exceed those of its non-innovative counterparts. The available empirical literature addressing this theoretical tension mostly supports the former hypothesis; we suggest that this finding is, in part, driven by the common practice of employing an ex post measure that already embodies a degree of succes…

How news affect the trading behavior of different categories of investors in a financial market

2015

We investigate the trading behavior of a large set of single investors trading the highly liquid Nokia stock over the period 2003-2008 with the aim of determining the relative role of endogenous and exogenous factors that may affect their behavior. As endogenous factors we consider returns and volatility, whereas the exogenous factors we use are the total daily number of news and a semantic variable based on a sentiment analysis of news. Linear regression and partial correlation analysis of data show that different categories of investors are differently correlated to these factors. Governmental and non profit organizations are weakly sensitive to news and returns or volatility, and, typica…

Is there a Nordic model of final disposal of spent nuclear fuel? Governance insights from Finland and Sweden

2017

This paper explores citizen participation in Swedish and Finnish regulatory processes for final disposal of spent nuclear fuel (SNF). Finland and Sweden are considered the most advanced worldwide in term of SNF disposal plans. Our aim is to analyze the institutional waste management frameworks, focusing on the role of civil society organizations (CSOs); how lay-people and civil society organizations have been able to participate and contribute to radioactive waste licensing processes; and the nature of radioactive waste risk debates. We review official documents of the waste companies and nuclear safety authorities, plus information from civil society organizations and laypeople. Our theore…

Realizing the social acceptance of community renewable energy: A process-outcome analysis of stakeholder influence

2014

This study shows how stakeholders influence the development of community renewable energy (CRE) schemes and how they are influenced by their outcome. It relies on information collected during 41 structured interviews with local people involved in CRE initiatives in seven regions of Europe. The interviews were thematically analyzed to identify different types of stakeholder influence. The findings show that stakeholder influence on CRE schemes take place at three distinct levels: macro, intercommunity and intracommunity. In addition, key stakeholders can support or hinder the development of a project according to whether or not they perceive that the output of the project may benefit or harm…

School and choice: An ethnography of a primary school with bilingual classes

2010

Based on a one-year ethnographic study of a primary school in Finland with specialised classes in Finnish and English (referred to as bilingual classes by research participants), this research traces how nationed, ethnicised, classed and gendered differences are produced and gain meaning in school. I examine several aspects of these differences: the ways teachers and parents make sense of school and of school choice; the repertoires of self put forward by teachers, parents and pupils of the bilingual classes, and the institutional and classroom practices in Sunny Lane School (pseudonym). My purpose is to examine how the construction of differentness is related to the policy of school choice…

Teacher-student interaction and lower secondary school students’ situational engagement

2019

Background: Prior research has shown that engagement plays a significant role in students’ academic learning. Aims: The present study sought to expand the current understanding of students’ engagement by examining how situational engagement during a particular lesson is associated with the observed teacher–student classroom interactions (i.e., emotional support, instructional support, and classroom organization) in the same lesson. Sample: The participants were 709 Grade 7 students (47.7% girls) from 59 classrooms in 26 lower secondary schools and 51 teachers. Methods: The data consisted of 155 video‐recorded lessons (90 language arts and 65 mathematics lessons) coded using the Classroom As…

Aussprachetraining im DaF-Unterricht in der Lehr- und Lernwelt 3.0.

2018

Everyone who acquires a new language at school or elsewhere has the right to learn good pronunciation. As phonetic errors are foreseeable, this paper begins by delineating deviations in (co)articulation and prosody which are typical of Italian learners of German, with the aim of examining how far these specific, predictable phonetic problems are treated in German textbooks used in Italy. The study shows that even modern textbooks do not consider phonetics in a satisfactory way. Today’s learning world 3.0 – not only interactive, but also shaped for the individual learner – is characterized by a growing number of Computer Assisted Language Learning (CALL) and special Computer Assisted Pronunc…

Mehr als Musik: Die sieben Dimensionen des Eurovision Song Contests

2008

"Der Eurovision Song Contest (ESC) ist der weltweit größte internationale Wettbewerb für populäre Musik und das erfolgreichste Fernsehunterhaltungsprogramm in Europa. Obwohl der ESC ursprünglich das Ziel verfolgte, die Entstehung neuer Lieder zu fördern, handelte es sich doch stets um ein von den Fernsehanstalten inszeniertes Medienereignis, das erst nachrangig musikökonomischen Zwecken dient. Für das Publikum ist der ESC auf Grund seiner Periodizität, seiner spezifischen Programmstruktur und nicht zuletzt des Zugehörigkeitsgefühls der Zuschauer, das auf Schemata nationaler und kultureller Identifikation beruht, zu einem hochgradig ritualisierten Medienereignis geworden. Seine Bedeutung geh…
