Probability Propagation in Selected Aristotelian Syllogisms
No full textThis paper continues our work on a coherence-based probability semantics for Aristotelian syllogisms (Gilio, Pfeifer, and Sanfilippo, 2016; Pfeifer and Sanfilippo, 2018) by studying Figure III under coherence. We interpret the syllogistic sentence types by suitable conditional probability assessments. Since the probabilistic inference of from the premise set is not informative, we add p(M|(S ee M))>0 as a probabilistic constraint (i.e., an ``existential import assumption'') to obtain probabilistic informativeness. We show how to propagate the assigned premise probabilities to the conclusion. Thereby, we give a probabilistic meaning to all syllogisms of Figure~III. We discuss applications like generalised quantifiers (like Most are ) and (negated) default

Probabilistic Semantics for Categorical Syllogisms of Figure II
No full textA coherence-based probability semantics for categorical syllogisms of Figure I, which have transitive structures, has been proposed recently (Gilio, Pfeifer, & Sanfilippo [15]). We extend this work by studying Figure II under coherence. Camestres is an example of a Figure II syllogism: from Every P is M and No S is M infer No S is P. We interpret these sentences by suitable conditional probability assessments. Since the probabilistic inference of P ̄|S from the premise set {M|P,M ̄|S} is not informative, we add p(S|(S∨P))>0 as a probabilistic constraint (i.e., an “existential import assumption”) to obtain probabilistic informativeness. We show how to propagate the assigned (precise or interval-valued) probabilities to the sequence of conditional events (M|P,M ̄|S,S|(S∨P)) to the conclusion P ̄|S . Thereby, we give a probabilistic meaning to the other syllogisms of Figure II. Moreover, our semantics also allows for generalizing the traditional syllogisms to new ones involving generalized quantifiers (like Most S are P) and syllogisms in terms of defaults and negated default
The Heterogeneous Economic Consequences of Works Council Relations
No full textI use a question about works council relations from the 2006 wave of the IAB Establishment panel to analyze the heterogeneous effects of works councils on productivity, wages, and profits. The results indicate that the effects differ significantly between works council relationship types in a systematic pattern. The overall findings are in line with productivity-enhancing and rent-sharing functions of works councils.Codetermination; Firm performance; Industrial relations; Works councils

ADAPTIVE SERVICE - CENTERED APPLICATIONS
No full textV diplomskem delu smo predstavili vse relevantne pojme v zvezi s prilagodljivimi storitvenimi aplikacijami, kot sta kvaliteta storitev (QoS) in spletni jezik ontologij za storitve (OWL-S), saj omogočajo boljšo in lažjo selekcijo med množico storitev, ki nudijo isto funkcionalnost, vendar imajo različne nefunkcionalne lastnosti. Opisali smo tudi nekatere obstoječe raziskave za zagotavljanje prilagodljivosti storitvenih aplikacij s pomočjo prilagodljivosti pri vsebovanih storitvah. Na podlagi opisanega smo s pomočjo storitvenega agenta zasnovali lastno implementacijo takšnega sistema.In this diploma we introduced all relevant information in connection with adaptive service-centred applications, like Quality of Services (QoS) and Web Ontology Language for Services (OWL-S). They enable better and easier selection amongst the numerous services, which offer the same functionality, but differ in non-functional properties. We also described some existing research for enabling the seamless execution of
service-centred applications with the help of adaptive services. Those researches then served as a basis for designing and implementing such a system with the help of a service agent
Web-based Testing of Congenital Amusia with the <i>Montreal Battery of Evaluation of Amusia</i>
No full textIn this article we present the results of a web-based testing of 117German undergraduate students with the Montreal Battery of Evaluation of Amusia (MBEA; Peretz et al. 2003). The MBEA is used to assess congenital amusia, a neuro-developmental disorder present in approximately 4% of the population, according to Kalmus & Fry(1980). Recently, criticism has arisen concerning the usage of the MBEA in relation to the prevalence of congenital amusia in the general population and the statistical evaluation of the results (Henry& McAuley, 2010; 2013, Pfeifer & Hamann 2015).We compare the results of our web-based study to a group of 111German students that was tested with a computer-implemented MBEA version under laboratory conditions (Pfeifer & Hamann 2015).We found significant differences between the web-based and the laboratory group based on their sum of correct responses. A Signal Detection Theory analysis of the data, which factors out response bias, however, shows that the discriminatory ability of both groups seems to be fairly similar. The results of the current study are used to critically discuss the validity of a web-based MBEA specifically butal so web-based testing more generally as a means of diagnosing congenital amusia
Use of renewable energy sources and cogeneration for self-supply with electrical and heat energy
No full textV diplomskem delu je predstavljena avtohiša in stanovanjski objekt v lasti Avtohiše Kos d.o.o., katere trenutno ogrevajo s pečjo na kurilno olje in s štirimi klimatskimi napravami. Prikazane so izvedbe več vetrnih tehnologij (vetrnic) iz različnih svetovnih trgov in hibridni sistem vetrne in sončne tehnologije, s katerimi bi bilo poskrbljeno za samooskrbo z električno energijo in za napajanje toplotne črpalke, ki bi ogrevala prostore. Kot razumna naložba je dodana še enota za kogeneracijo na zemeljski plin, ki bi s pomočjo vetrnice in sončnih celic zagotavljala toplotno energijo in bi hkrati pokrivala vršne potrebe električne energije. Podane so energetska, stroškovna in finančna analiza s programom RETScreen, na podlagi analiz pa primerjane donosnosti investicij.The thesis presents a car dealership and a residential facility, owned by Avtohiša Kos d.o.o., which are currently heated by a heating oil stove and four air conditioners. Various implementations of wind technologies (wind turbines) from different markets worldwide are shown, as well as a hybrid system of wind and solar technology, which would provide self-supply with electricity and power supply for a heat pump to heat the premises. A natural gas cogeneration unit was added as a reasonable investment, which would with help of wind turbine and solar panels provide heat and while covering peak electricity requirements. Energy, cost and financial analysis using program RETScreen are given, and on the basis of the analysis compared profitabilities of investments
