Wymuszenie rozbójnicze i rozbiór - analiza znamion czynów zabronionych na tle statystyk sądowych
2018
Artykuł poddaje analizie kontrowersyjne zagadnienie różnic występujących pomiędzy przestępstwem wymuszenia rozbójniczego a rozbojem. W rozważaniach odniesiono się do doktryny oraz orzecznictwa wskazując na liczne wątpliwości pojawiające się w tej materii. Podjęto również próbę wyznaczenia granic jakie dzielą te przestępstwa. W części drugiej odniesiono się do statystyk sądowych obrazujących dynamikę czynu zabronionego wymuszenia rozbójniczego. W szczególności zaprezentowano dane dotyczące liczby przestępstw wszczętych oraz stwierdzonych porównując je również z przestępstwem rozboju. Wskazano nadto liczbę prawomocnych przestępstw z art. 282 k.k. z uwzględnieniem płci oraz wieku sprawców.
A Scale of Knowledge and Beliefs about Developmental Dyslexia: Scale Development and Validation
2014
Abstract The purpose of this study was to create and validate a scale measuring knowledge and beliefs regarding developmental dyslexia. A four-step procedure was followed to achieve this objective. A literature review generated a preliminary pool of 65 items. A group of 12 university teachers of learning disabilities read the items for content and face validity and offered comments. Based on their comments, some items were combined, and confusing items were changed or eliminated, which left a scale of 50 items, with the response options of true (V), false (F) or dont know (NS). Later, each participant, using a description of the scales, placed each item into one of the three subscales. An i…
Interpreting the decomposition of gender earnings gap
2010
In this paper we discuss a decomposition of the gender monthly earnings differential into three components: the first is due to differences in individual characteristics, the second is due to discrimination and the last to the differential in hours worked. The Oaxaca-Blinder hourly wage decomposition is perfectly integrated into the decomposition of the monthly earnings gap. In order to evaluate the effects of this components on the monthly earnings gap, we calculate counterfactual earnings gaps, estimating what would happen if various aspects relating to the two genders were equal (for example, educational level), and then we compare these with the empirical earnings gap. The aim of the co…
Recurrence time distribution and temporal clustering properties of a cellular automaton modelling landslide events
2018
Abstract. Reasonable prediction of landslide occurrences in a given area requires the choice of an appropriate probability distribution of recurrence time intervals. Although landslides are widespread and frequent in many parts of the world, complete databases of landslide occurrences over large periods are missing and often such natural disasters are treated as processes uncorrelated in time and, therefore, Poisson distributed. In this paper, we examine the recurrence time statistics of landslide events simulated by a cellular automaton model that reproduces well the actual frequency-size statistics of landslide catalogues. The complex time series are analysed by varying both the threshold…
The Latent Factors Behind the Urban Travel Behaviour
2014
Abstract This research aims to explore the impact of latent variables, mirroring the users’ preferences, on the individual decision making process regarding the mode of transport. The paper describes the first results of an ongoing research activity, which derives from a pilot study carried out in Palermo. The authors have administered to a sample of travellers a questionnaire and they simulated the mode choice behaviour referring to the random utility theory. Then the transport demand over the entire area of Palermo has been studied in order to design the cordon pricing scenario with the application of an additional cost on private car dedicated to a selected area of the historic centre of…
CHOOSING OF OPTIMAL REFERENCE SAMPLES FOR BOREAL LAKE CHLOROPHYLL A CONCENTRATION MODELING USING AERIAL HYPERSPECTRAL DATA
2018
Abstract. Optical remote sensing has potential to overcome the limitations of point estimations of lake water quality by providing spatial and temporal information. In open ocean waters the optical properties are dominated by phytoplankton density, while the relationship between color and the constituents is more complicated in inland waters varying regionally and seasonally. Concerning the difficulties relating to comprehensive modeling of complex inland and coastal waters, the alternative approach is considered in this paper: the raw digital numbers (DN) recorded using aerial remote hyperspectral sensing are used without corrections and derived by means of regression modeling to predict C…
SCAN-TO-BIM FOR THE MANAGEMENT OF HERITAGE BUILDINGS: THE CASE STUDY OF THE CASTLE OF MAREDOLCE (PALERMO, ITALY)
2020
Abstract. Conservation and preservation of heritage buildings require the knowledge and sharing of a great deal of data and information about buildings. Such information comes from the different disciplines involved in the restoration and maintenance processes. The integration and use of all this information in a single working environment is a key factor for the success of historical building conservation and management projects. Heritage (or Historic) Building Information Modelling (HBIM) is nowadays the most appropriate tool to collect and manage all data related to Architectural Heritage. The HBIM process requires an in-depth knowledge of the historical building that can be achieved usi…
MODELLING VAGUE KNOWLEDGE FOR DECISION SUPPORT IN PLANNING ARCHAEOLOGICAL PROSPECTIONS
2012
Abstract. Most archaeological predictive models lack significance because fuzziness of data and uncertainty in knowledge about human behaviour and natural processes are hardly ever considered. One possibility to cope with such uncertainties is utilization of probability based approaches like Bayes Theorem or Dempster-Shafer-Theory. We analyzed an area of 50 km2 in Rhineland Palatinate (Germany) near a Celtic oppidum by use of Dempster-Shafer's theory of evidence for predicting spatial probability distribution of archaeological sites. This technique incorporates uncertainty by assigning various weights of evidence to defined variables, in that way estimating the probability for supporting a …
Image-based and range-based 3D modelling of archaeological cultural heritage: The telamon of the temple of Olympian Zeus in Agrigento (Italy)
2012
Abstract. The Temple of Olympian Zeus in Agrigento (Italy) was one of the largest temple and at the same time one of the most original of all the Greek architecture. We don’t know exactly how it was because the temple is now almost completely destroyed but it is very well-known for the presence of the Telamons. The Telamons were giant statues (about 8 meters high) probably located outside the temple to fill the interval between the columns. In accordance with the theory most accredited by archaeologists the Telamons were a decorative element and also a support for the structure. However, this hypothesis has never been scientifically proven. One Telamon has been reassembled and is shown at t…
CLUSTERING INCOMPLETE SPECTRAL DATA WITH ROBUST METHODS
2018
Abstract. Missing value imputation is a common approach for preprocessing incomplete data sets. In case of data clustering, imputation methods may cause unexpected bias because they may change the underlying structure of the data. In order to avoid prior imputation of missing values the computational operations must be projected on the available data values. In this paper, we apply a robust nan-K-spatmed algorithm to the clustering problem on hyperspectral image data. Robust statistics, such as multivariate medians, are more insensitive to outliers than classical statistics relying on the Gaussian assumptions. They are, however, computationally more intractable due to the lack of closed-for…
