The Crisis on the Labor Market in Romania
2007
In the last 17 years the labor market in Romania has suffered deep changes. We can found two distinct stages regarding the evolutions on the labor market in Romania after 1989. The first stage, which includes the period 1990 – 2003, is defined as a period of deep restructurations of the Romanian economy. It is characterized as a period of relatively high unemployment and the undertaken actions were directed mainly at limiting the unemployment and its harmful effects on the society. We consider that after 2005 the employment evolution heads towards a new crisis on the labor market, but its cause is not a high unemployment, but rather an offer dropping on the labor market. The causes and the …
Overview of Power Electronic Switches: A Summary of the Past, State-of-the-Art and Illumination of the Future.
2020
As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progr…

Estimation of the Time-Variant Velocity of a Single Walking Person in Two-Dimensional Non-Stationary Indoor Environments Using Radio-Frequency Techni…
2020
Accurate estimation of the time-variant (TV) velocity of moving persons/objects in indoor spaces is of crucial importance for numerous wireless indoor applications. This article introduces a novel iterative procedure to estimate the TV velocity, i.e., TV speed and TV angle-of-motion (AOM), of a single moving person in 2D indoor environments by using radio-frequency (RF) techniques. The indoor area is equipped with a distributed 2 × 2 multiple-input multiple-output (MIMO) system. The proposed method is divided into two parts. In the first part, we estimate the path gains and the instantaneous Doppler frequencies by fitting the exact spectrograms of the complex channel gains of a 2D no…
The Need to Approach the Management of the Tourist Destination by the Central and Local Public Authorities in Romania
2017
Abstract In the medium and long term, priorities in the development of tourism aim to develop a complex tourist offer, making the most of the natural and anthropogenic resources existing in connection with the preservation of the environment and the heritage. On the long run, it will contribute to raising the living standards of the population, especially social categories with lower chances of reintegration into the labour market (people made redundant in industry, elderly people etc.). Implementation of the strategy at regional level must be achieved through an active partnership between Romanian public authorities, economic agents and private investors, with the involvement of the federa…
Open Service Innovation: The Case of Tourism Firms in Scandinavia
2016
Most empirical research investigating open innovation has focused on the development of new physical products in manufacturing industries, whereas open service innovation has not been researched correspondingly. Services have some characteristics that distinguish them from physical products, which may affect the types of open innovation practice utilised during service innovation processes. Tourism services comprise a subset of services that is particularly distant from tangible products. Therefore, the exploration of how tourism firms utilise different types of open innovation practice offers a valuable opportunity to learn about the nature of open service innovation practices. Thus, this …
Developments on the International Hotel Chain Market
2018
Tourism is a mass phenomenon, and as a result, the number of accommodation capacities has increased enormously in recent years, especially in hotel groups, whether integrated or voluntary. Currently, a large part of hotel chains has subsidiaries around the world and covers major aspects of international tourism demand through their own distribution systems. Under these circumstances, this paper aims to analyse the global evolution of the main hotel chains, while also presenting performance issues, including average daily rate (ADR), and occupancy rate.
A New Perspective on the Relationship between Trading Variables and Volatility in Futures Markets
2017
In this paper, we study the relationship between trading-related variables and volatility in futures markets, from a new unifying perspective, which is based on the separation of open and closed positions. Volatility in stock index futures markets (Standard & Poor’s 500, DAX 30 and Nikkei 225) is related to the flow of contracts entered into the markets and the flow of contracts that are closed out. In general, the daily changes in the number of open and closed positions are both positively correlated with volatility. Additionally, there is a stronger positive relationship between the number of open (respectively, closed) positions and contemporaneous volatility on those days when t…
Hvilke faktorer påvirker IPLOS registreringen i primærhelsetjeneste?
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Background: According to the «Regulations on pseudonymous register for individual health and care statistics»the municipality sector commits itself to registertheir services and patients in the municipalities. Based on this, a registration system was developed which is integrated into the EPR systems used in the municipal sectors. IPLOS is the registry where all data is collected and used for statistics and distribution of earmarked funds. Reporting to the IPLOS registry is an imposed task that can pose a number of challenges for the health personnel who perform the registrations.Purpose:The purpose of the assignm…
