Several variants of a first-order simplification rule for nonnormal form tableaux using syntactic constraints are presented. These can be used as a framework for porting methods like unit resolution or hyper tableaux to non-normal form free variable tableaux.

An alternative approach to the semantics of definite descriptions was proposed by Heim in her dissertation [1982]. Heim assigns to pragmatics a larger part of the task of specifying the meaning of definite descriptions than the neo-Russellians do. In Heim’s theory, definite and indefinite NPs are semantically equivalent, and both introduce free variables. The truth conditions proposed by Heim f...

In this study the effects of school and classroom climate and teacher’s behavior on Italian students’ mathematical achievement score in PISA 2012 were investigated. Simple and scale indices provided by the PISA database, constructed by responses from the students’ and principals’ background questionnaires, were considered as predictive variables of the math achievement scores. Multilevel models...

background: it is believed that improved safety culture/climate is a fundamental element to accident prevention. therefore, development a scale to assess safety climate is a step towards accident control. the purpose of this study was to construct a persian safety climate questionnaire. methods: the study took place in tehran and esfahan oil refineries in iran in 2010. an initial questionnaire ...

11 The influence of climate on biodiversity is an important ecological question. Vari12 ous theories try to link climate change to allelic richness and therefore to predict 13 the impact of global warming on genetic diversity. We model the relationship be14 tween genetic diversity in the European beech forests and curves of temperature 15 and precipitation reconstructed from pollen databases. O...

The hedonic price literature suggests that locations with more favourable characteristics should display compensating wage and house price differentials. Estimates of the marginal willingness to pay for small changes in climate variables are derived using the hedonic price technique applied to Italian data. A hedonic price model was specified in terms of January and July averages. There exists ...

The economics of climate change involves a vast array of uncertainties, complicating both the analysis and development of climate policy. This study presents the results of the first comprehensive study of uncertainty in climate change using multiple integrated assessment models. The study looks at model and parametric uncertainties for population, total factor productivity, and climate sensiti...

OBJECTIVE To determine whether the relationship between organizational climate and employee mental health is consistent (ie, invariant) or differs across four large hospitals, and whether organizational efficiency mediates this relationship. METHODS Participants (total N = 5316) completed validated measures of organizational climate variables (social climate, participatory management, goal cl...
