Comparing the Impact of the Net Income Versus the Comprehensive Income Over the Share Price for Companies Listed on the Bucharest Stock Exchange
2020
Abstract As a consequence of adopting the IFRS in Romania, starting with 2012, for companies whose securities are admitted for trading on a regulated market, financial reporting demarches include ascertaining the comprehensive income in addition to the net income. The present paper aims at investigating how the share price evolves considering the level of the comprehensive income as compared to the reported net income, in a multiannual empirical study implying panel data analysis through Pooled OLS, Fixed Effects and Random Effects models processed through EViews. Furthermore, the informational and decisional utility of the two main forms of disclosed accounting results (the net income and …
Methodology and trends for an intelligent transport system in developing countries
2018
Abstract Increasingly, the technologies that are used in telecommunications contribute to improve intelligent transport systems. These technologies are systems that offer several concepts like vehicular ad hoc networks, which allow reduction of traffic accidents, traffic congestion and consequently increase road safety and the comfort of road users. Developing countries in general and those of sub-Sahara in particular do not have telecommunication infrastructures, even road infrastructures for the implementation of an intelligent transport system. Moreover, with the serious increase in vehicles in these countries, the problem of traffic regulation arise especially in the inter-urban context…
Branch-and-Cut for the Split Delivery Vehicle Routing Problem with Time Windows
2019
The split delivery vehicle routing problem with time windows (SDVRPTW) is a notoriously hard combinatorial optimization problem. First, it is hard to find a useful compact mixed-integer programming (MIP) formulation for the SDVRPTW. Standard modeling approaches either suffer from inherent symmetries (mixed-integer programs with a vehicle index) or cannot exactly capture all aspects of feasibility. Because of the possibility to visit customers more than once, the standard mechanisms to propagate load and time along the routes fail. Second, the lack of useful formulations has rendered any direct MIP-based approach impossible. Up to now, the most effective exact algorithms for the SDVRPTW hav…
Zastosowanie metody AHP do tworzenia rankingu kryteriów oceny wiarygodności witryn internetowych
2020
Wiedza w zakresie pozyskiwania, oceny i efektywnego wykorzystania informacji jest niezbędna nie tylko uczniom, studentom i nauczycielom (w tym akademickim), ale także projektantom i twórcom witryn oraz dostawcom treści internetowych. W szczególności dotyczy to możliwości oceny wiarygodności witryn internetowych. Problemem jest nie tylko wybór odpowiednich kategorii i kryteriów tej oceny, ale także uwzględnienie wszystkich tych kryteriów w końcowej ocenie. Celem artykułu jest ustalenie rankingu ważności kryteriów oceny wiarygodności witryn internetowych z punktu widzenia ekspertów. Wymagało to udzielenia odpowiedzi na następujące pytania: - Jak stworzyć ramy oceny wiarygodności witryn? - Któ…
History of Data Centre Development
2012
International audience; Computers are used to solve different problems. For solving these problems computer software and hardware are used, but for operations of those computing facilities a Data Centre is necessary. Therefore, development of the data centre is subordinated to solvable tasks and computing resources. We are studying the history of data centres’ development, taking into consideration an understanding of this. In the beginning of the computer era computers were installed in computing centres, because all computing centres have defined requirements according to whom their operation is intended for. Even though the concept of ‘data centre’ itself has been used since the 1990s, t…
The development of a suite of computer-based diagnostic tests based on the Common European Framework
2005
DIALANG is an on-line language assessment system, which contains tests in 14 European languages and is based on the Common European Framework of Reference (CEFR). It is the first major testing system that is oriented towards diagnosing language skills and providing feedback to users rather than certifying their proficiency. This article describes the contents of Version 1 of DIALANG and the way in which the system works. This is followed by an account of the development of DIALANG tests and of the pilot testing and standard setting procedures. The results of the first analyses of items and self-assessment statements, and of the standard setting procedures, are reported. The article focuses…
Retrieving Monitoring and Accounting Information from Constrained Devices in Internet-of-Things Applications
2013
Part 6: Monitoring Mechanisms; International audience; Internet-of-Things (IoT) is envisioned to provide connectivity to a vast number of sensing or actuating devices with limited computational and communication capabilities. For the organizations that manage these constrained devices, the monitoring of each device’s operational status and performance level as well as the accounting of their resource usage are of great importance. However, monitoring and accounting support is lacking in today’s IoT platforms. Hence, this paper studies the applicability of the Constrained Application Protocol (CoAP), a lightweight transfer protocol under development by IETF, for efficiently retrieving monito…

The Dark Side of the Web—A Risk for Children and Adolescents Challenged by Isolation during the Novel Coronavirus 2019 Pandemic
2021
In response to the global novel coronavirus disease 2019 (COVID-19) pandemic, many countries around the world adopted social isolation measures to contain the spread of the virus.1 For children and adolescents, limitations in faceto-face activities and interactions with their traditional peer groups has been a frustrating experience. After disease containment measures, which included school closures, social distancing, and home quarantine, children and adolescents faced a prolonged state of physical isolation from their peers, teachers, extended family, and community networks that affects their emotional and behavioral health.2 Parents and pediatricians are reporting signs of mental distres…
