The Role of Assumptions in Ohlson Model Performance: Lessons for Improving Equity-Value Modeling

2021

In this paper, we test whether the short-run econometric conditions for the basic assumptions of the Ohlson valuation model hold, and then we relate these results with the fulfillment of the short-run econometric conditions for this model to be effective. Better future modeling motivated us to analyze to what extent the assumptions involved in this seminal model are not good enough approximations to solve the firm valuation problem, causing poor model performance. The model is based on the well-known dividend discount model and the residual income valuation model, and it adds a linear information model, which is a time series model by nature. Therefore, we adopt the time series approach. In…

SOLUZIONI OPERATIVE ED ASPETTI QUALITATIVI PER LA GEOCODIFICA DI POPOLAZIONI IN AMBITO SANITARIO.

2015

IntroduzioneL'utilizzo dei Geographic Information Systems (GIS) in ambito sanitario, continua a ricevere grande attenzione. La disponibilità di informazioni sulla localizzazione degli individui, consente di effettuare associazioni territoriali sulle cause delle patologie, nonché di indagare aspetti legati alla distribuzione dei servizi sanitari ed all'equità di accesso alle cure. ObiettiviAnalizzare le principali problematiche e le soluzioni operative per la geocodifica di popolazioni e proporre un indice di qualità della geocodifica di cui poter tenere conto in sede di analisi. MetodiCome caso studio vengono illustrate le fasi che hanno portato alla georeferenziazione di indirizzi residenz…

Geobotanical approach to detect land-use change of a Mediterranean landscape: a case study in Central-Western Sicily

2018

A landscape is a palimpsest of the interactions between human activities and ecological dynamics. In an interdisciplinary perspective of dialogue between the ‘Two Cultures’ (Natural Sciences and Humanities), a study of a rural area has been carried out through a reading of plant ecosystems as signs of human impact. The purpose of this paper—as part of the project ‘Harvesting Memories’: Ecology and landscape archaeology of Castro/Giardinallo Valley and Mt. Barrau district (Corleone, Palermo, Sicily)—is to analyse the formative-processes of a Sicilian rural landscape and its changes in the last century. A key element in the reconstruction of the formation of the present landscape is the serie…

Social Insurance Accounting for a Notional Defined Contribution Scheme Combining Retirement and Long-Term Care Benefits

2018

This paper develops a social insurance accounting model for a notional defined contribution (NDC) scheme combining retirement and long-term care (LTC) contingencies. The procedure relies on standard double-entry bookkeeping and enables us to compile a “Swedish” type actuarial balance sheet (ABS) following a framework equivalent to an open group approach. This methodology is suitable for reporting the system’s solvency status and can show periodical changes in the system’s financial position by means of an income statement. The information underpinning the actuarial valuation is based on events and transactions that are verifiable at the valuation date, without consid…

LKS-92 Coordinates Transformation to ITRF2000

2014

LKS-92 is Latvian geodetic coordinate system used as an EUREF89 realization in Latvia. LKS-92 is official coordinate system for procuring of essential geospatial data. For aeronautical and other purposes ITRF2000 is used in publication of geospatial data. Research is done to obtain transformation parameters from LKS-92 realization epoch 1992.75 through LatPos to ITRF2000 epoch 2000.00. Valuation of two different coordinate adjustment strategies and accuracy of parameters is done. Results of research could be used for transformation from LKS-92 to ITRF2000 for all kind of geospatial data.

Effects of training and assessment in vocational education and training (VET): Reflections on the methodology of assessing the development of traits …

2006

Abstract This article focuses on the development of traits of self-regulation within vocational education and training (VET). This perspective is in accordance with the general objective of VET within the German speaking countries and is addressed in the objective “education and training for the ability of self-directed planning, regulation and evaluation of vocational performance”. In order to foster these and other relevant abilities, specific vocational training programs were developed and implemented in a training center in Switzerland. One such program was evaluated in a longitudinal study. From 1999 to 2003, a cohort of more than 100 aprentices was monitored with respect to the develo…

A study of thyme germplasm in Sicily

2009

hyme is characteristic of the Mediterranean and is of interest for its multifunctional nature. It is widely used in seasoning and flavouring, in herbal products and cosmetics. The versatility of this species means it is also useful in the protection of areas prone to erosion or an ornamental plant when designing low-maintenance gardens. Thyme germplasm constitutes a large part of the wild flora in Sicily and is a potentially useful source of genetic variability. On the basis of this, in the two-year period from 2004-2005, research was carried out on wild thyme accessions. These were used to evaluate both its productivity and individual biotypes with the functional characteristics most sough…

TWO YEARS OF STUDIES INTO NATIVE BERMUDAGRASS (CYNODON SPP.) GERMPLASM FROM SICILY (ITALY) FOR THE CONSTITUTION OF TURF CULTIVARS

2008

Bermudagrass (Cynodon spp.) is the most widely used warm season turf species in the world for sport, lawn and utility turfs. The species is widespread in Sicily (Italy) where it exhibits a large range of diverse morphological characteristics due to a long process of adaptation to varying climatic and soil conditions of the island. In order to exploit the bermudagrass genetic resources and establish a germplasm bank for use in various plant breeding programmes, bio-agronomic evaluation tests were carried out on the 40 Sicilian biotypes of Cynodon spp. from 2002 to 2004 at the experimental farm “Orleans”, University of Palermo. The accessions were compared to the standard cultivar ‘Savannah’,…
