Ocena wiarygodności internetowych serwisów ubezpieczeniowych w Polsce

2016

Wiarygodność partnera transakcji czy usług realizowanych przez Internet stanowi istotny czynnik dla dalszego rozwoju gospodarki internetowej. Dotyczy to między innymi rozwoju ubezpieczeń internetowych. Dlatego umiejętność oceny wiarygodności serwisów WWW staje się ważnym narzędziem w rywalizacji na rynku ubezpieczeniowym. Celem artykułu jest przedstawienie wyników oceny wiarygodności serwisów WWW wybranych ubezpieczycieli prowadzących działalność w Polsce. W artykule pokazano, że kryteria oceny wiarygodności serwisów internetowych można przyporządkować do trzech wymiarów; są nimi: zdolność serwisu do zapewniania wiarygodności, życzliwość projektantów, twórców i administratorów serwisu w zak…

Mercato digitale e sistema delle successioni mortis causa

2022

The work aims to examine the curvature impressed by the current order of the market and of the "algorithmic" society, centered on social network platforms, on principles and categories of classical hereditary law, putting the system of mortis causa succession into reaction with the matter of relationships and personal rights developed on the web, marked by the changes that shake the European and internal legal framework. The study is organized according to a tripartite scheme, which distinguishes the succession in contracts for the supply of digital services, from the transmission of rights on user-generated content and on the personal data of the deceased. To then keep a unity in the const…

Univariate and multivariate properties of wind velocity time series

2009

We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.

A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network

2016

The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…

"Co to są czary? Co za znaki ich?" Litewskie kazanie i sposoby na czary z końca XVII i XVIII w

2018

Witchcraft as a crime attracted the attention of Polish-Lithuanian society in many aspects at the turn of 17th and 18th centuries. On the one hand, it was connected with a belief in its efficiency, in the existence of witches and sorcerers, and their covenant with the devil. The article analyzes two manuscripts: a prayer „Modlitwa przeciwko czarom i niebezpieczeństwom” and a sermon „ Jako się strzedz czarów i potwarzy o nie”. The sermon utilizes contemporary rhetoric, stresses the importan-ce of sin and appeals to the receivers through fear. What is somewhat surprising, the text maintains that most witchcraft happened with God’s permission, as God allows the devil to function in the society…

The MIMOSE Approach to Support Sustainable Forest Management Planning at Regional Scale in Mediterranean Contexts

2017

In recent decades, Mediterranean landscapes have been affected by human-induced drivers, such as land use and climate change. Forest ecosystems and landscapes have been particularly affected in mountainous regions due to limited management and stewardship, especially in remote areas. Therefore, there is a need to set up new strategies to enhance ecosystem services in forested areas which, in turn, will benefit local communities and economies. In this study, we implemented a new approach—Multiscale Mapping of Ecosystem Services (MIMOSE)—to assess ecosystem services in Mediterranean forests located in a mountainous region of Italy. We spatially assessed timber provision and carbon sequestrati…

Une qualité d’emploi mitigée : qu’est-ce qui motive les aides à domicile?

2014

The employment quality in the sector of home care services raises a number of questions. In this sector, job positions are hard to fill and they meet unattractive working conditions. Overall, the sector is suffering from a rather negative image. This article, through a qualitative study, identifies the differentiation factors of employee satisfaction in terms of employment quality, and the work motivation factors, in an environment that is not always favorable. The results show that the perception of employment quality is not homogeneous, but rather produces convergent representations revealing issues with human resources management. A variety of factors appear to motivate the home care ser…
