Repeat Assessed Values Model for Housing Price Index

2017

Abstract This study proposes an innovative methodology, named Repeat Appraised Price Model (RAV), useful for determining the price index numbers for real estate markets and the corresponding index numbers of hedonic prices of main real estate characteristics in the case of a lack of data. The methodological approach proposed in this paper aims to appraise the time series of price index numbers. It integrates the principles of the method of repeat sales with the peculiarities of the Hedonic Price Method, overcoming the problem of an almost total absence of repeat sales for the same property in a given time range; on the other hand, the technique aims to overcome the limitation of the repeat …

Principals’ views on changes in the provision of support for learning and schooling in Finland after educational reform

2019

Recently, the large-scale reforms of special education have been carried out in many countries. This study focuses on the latest Finnish reform of special education in compulsory education. As principals lead educational reforms in schools, their role in the implementation of reform is significant. The study explores principals’ views on the changes in support arrangements after the educational reform. We used latent class analysis to identify the subgroups of principals who share similar views. In addition, we examined the relationship between the subgroups and individual, school, and municipal level factors using multinomial logistic regression analysis. Four subgroups were identified: im…

Business models, small firms, and performance in knowledge-intensive based services. A study in the private health sector

2020

During the last years, and due to social and economic changes, the demand for private health services (PHS) is growing. A more significant number of companies appeared under different business model formulas. Besides the traditionally independent professionals, other types of entrepreneurs appeared under associated business. As a result of these changes, there are differences in how these services are provided and their performance. OBJECTIVES: This work is proposed to study the business model effect on small private health service companies' activity and analyze institutions’ and intellectual capital's role in their performance. METHODOLOGY: A qualitative-quantitative mixed method was desi…

The Bayesian estimation of private investment in Finland

2009

Abstract This paper estimates an investment equation for private investment using Bayesian estimation techniques. In the paper we derive the optimal capital accumulation behavior in the model economy from the households’ optimization problem of utility. The equation is derived as in Smets and Wouters (2003). The model contains costly adjustment of investment and random shocks to adjustment cost function. The driving variable of investment is Tobin Q variable. The empirical proxy for Tobin Q in this paper is the ratio of OMX Helsinki Cap Index to the price index of the physical capital. The investment series is the seasonally adjusted private investment in quarterly national accounts. The AR…

La valeur économique des paysages des villes périurbanisées

2007

La recherche présentée ici propose une méthode de description et d’évaluation des caractéristiques d’un paysage qui combine la géographie quantitative et l’économétrie des modèles hédoniques. Un modèle géographique produit des indices caractérisant les paysages à partir d’une reconstitution de la vue depuis le sol, en tenant compte des effets du relief et des masques que les objets hauts opposent à la vue. Il décrit la quantité de paysage vu par un observateur au niveau du sol en la répartissant entre 13 types d’occupations du sol. Les variables produites par le modèle géographique sont utilisées dans des régressions hédoniques qui permettent d’évaluer l’impact des attributs paysagers ain…

Modelling Environmental Problem-Solving Through STEAM Activities : 4Dframe's Warka Water Workshop

2016

In this paper the Korean 4Dframe educational modelling kit’s rich capacities are presented within a STEAM (Science, Technology, Engineering, Arts and Mathematics) education workshop. The workshop is an adaptation of the Warka Water social design project, launched by the architect Arturo Vittori in response to Ethiopia’s diminished sources of drinking water. Participants of the workshop will study the geometry of the Warka Water tower and understand its water harvesting technique, which is based on collecting water from the air. peerReviewed

Modelling Environmental Problem-Solving Through STEAM Activities : 4Dframe's Warka Water Workshop

2016

(No title)

2003

The aim of this work is to study multiobjective optimization problems with or without dynamics and the generalized Bolza problem and its applications. After having pointed out some concepts of nonsmooth analysis, we begin the first part of this thesis with the existence of Lagrange multipliers for multiobjective optimization problems in infinite dimension with a general preference. We introduce the regularity of preference and use calmness qualification condition we establish the existence of Karush-Kuhn-Tucker multipliers. This allows us to obtain Fritz-John multipliers in terms of the approximate subdifferential by Ioffe. Then we derive similar results when the preference is defined by a …

Didáctica de las ciencias experimentales y sociales

1992

Resumen basado en el del autor. Resumen también en inglés El planteamiento sistemático del proceso de enseñanza-aprendizaje estudiado desde el modelo de la teoría de la comunicación humana, lleva a considerar la situación educativa como el escenario real en que se resuelve la instrucción. La situación educativa concreta en el espacio y en el tiempo el proceso de enseñanza-aprendizaje, tanto para la educación formal como la no formal, siendo por lo tanto el espacio sociotemporal en el que a través de una amplia gama de interacciones se produce una secuencia de aprendizaje. Si analizamos las tareas que desde la Psicología de la Instrucción se han efectuado respecto a la situación educativa, e…

Linear Types for Higher Order Processes with First Class Directed Channels

1995

Abstract We present a small programming language for distributed systems based on message passing processes. In contrast to similar languages, channels are one-to-one connections between a unique sender and a unique receiver process. Process definitions and channels are first class values and the topology of process systems can change dynamically. The operational semantics of the language is defined by means of graph rewriting rules. A static type system based on the notion of linear types ensures that channels are always used as one-to-one connections.
