ECONOMIC CRISIS SUSTAINS BLACK MARKET
2012
The purpose of this research is to bring out the fact that during the periods of economic crisis, the black market finds a warm place to develop and even to diversify the ways of expressing. Based on some data of the National Institute of Statistics and the Organization for Economic Co-operation and Development (OECD1 ) , I’m trying to prove the fact that during the last two years while the world economic crisis has occurred, the black market has been increasing and there have been new forms of expressing this phenomenon. Although there are some positive ways of this phenomenon, on the whole, the increasing of the black market percent of GDP represents a wound within a healthy economy, whic…
COMPARATIVE STUDY OF THE DECISION-MAKING PROCESS IN SMES AND IN LARGE COMPANIES
2012
This article presents the importance of the decisional act in the entrepreneurial process, trying to emphasize its implications in various situations faced by managers and decision factors. Starting with the classic definition of the “decision” concept, this paper extends its meaning by applying it on the economic field and by deepening its meaning in the economic field, shaping the imperative requests a decision has to make. Narrowing the research field to the sphere of small and medium-sized enterprises, the analysis of the decision is made on their level, being built on the antithesis SME- large company. The results of the study consist in the appreciation of the importance the decision …
CONSIDERATIONS REGARDING REGULATIONS ON FINANCIAL MARKETS IN THE CONDITIONS OF ROMANIA AS A EU MEMBER STATE
2018
Financial markets are increasingly becoming an area of major interest to the European Union in its efforts to achieve competitive global development levels similar to those of the United States. The Lisbon Agenda is a testimony to this, although the latest assessments are not at all optimistic about the achievement of the target as expected for 2010. To meet its objectives, the EU has generated a comprehensive package of regulatory initiatives, composed of directives and regulations that translate its policies into the field. The paper aims at a careful review of all of them. Approximation of investment and capital markets is made from the two major chapters of Community policies whose free…
THE IMPORTANCE OF REGIONALIZATION IN IMPROVING THE PROCESS OF
2015
The interest to study the impact of regionalization on the absorption of EU funds is a major and timely subject, since on the one hand Member States should reform their institutional architecture and management tools to enable efficient cooperation with European structures, and on the other hand there is huge opportunity for economic and social development funded from European resources whose effective access can only be made based on an appropriate organizational framework. The regionalization process in Romania has experienced delays entailing a disadvantage in terms of the progress in the national socio-economic development. In the present study we aimed to identify the main weaknesses i…
Performance Improvement of a Drag Hydrokinetic Turbine
2021
Hydropower is at present in many locations, among all the other possible renewable energy sources, the best one for net cost per unit power. In contrast to traditional installation, based on water storage in artificial basins, free flow river turbines also provide a very low environmental impact due to their negligible effect on solid transport. Among them, kinetic turbines with vertical axis are very inexpensive and have almost zero impact on fish and local fauna. In application to tidal waves and sea waves, where vertically averaged velocities have alternate direction, a Savonius rotor also has the advantage of being productive during the whole time cycle. In this work, the effect of an u…
Fish Welfare in Aquaponic Systems: Its Relation to Water Quality with an Emphasis on Feed and Faeces—A Review
2017
Aquaponics is the combination of aquaculture (fish) and hydroponic cultivation of plants. This review examines fish welfare in relation to rearing water quality, fish feed and fish waste and faeces to develop a sustainable aquaponic system where the co-cultured organisms, fish, bacteria in biofilters and plants, should be considered holistically in all aquaponics operations. Water quality parameters are the primary environmental consideration for optimizing aquaponic production and for directly impacting fish welfare/health issues and plant needs. In aquaponic systems, the uptake of nutrients should be maximised for the healthy production of the plant biomass but without neglecting the best…
2018
Tetraspanins (Tspans) are a family of four-span transmembrane proteins, known as plasma membrane “master organizers.” They form Tspan-enriched microdomains (TEMs or TERMs) through lateral association with one another and other membrane proteins. If multiple microdomains associate with each other, larger platforms can form. For infection, viruses interact with multiple cell surface components, including receptors, activating proteases, and signaling molecules. It appears that Tspans, such as CD151, CD82, CD81, CD63, CD9, Tspan9, and Tspan7, coordinate these associations by concentrating the interacting partners into Tspan platforms. In addition to mediating viral attachment and entry, these …
Loss Aversion and Risk Aversion in Non-Clinical Negative Symptoms and Hypomania
2020
In the field of behavioral decision-making, “loss aversion” is a behavioral phenomenon in which individuals show a higher sensitivity to potential losses than to gains. Conversely, “risk averse” individuals have an enhanced sensitivity/aversion to options with uncertain consequences. Here we examine whether hypomania or negative symptoms predict the degree of these choice biases. We chose to study these two symptom dimensions because they present a common theme across many syndromes with compromised decision-making. In our exploratory study, we employed a non-clinical sample to dissociate the hypomanic from negative symptom dimension regarding choice behavior. We randomly selected a sample …
Ledrappier-Young formula and exact dimensionality of self-affine measures
2017
In this paper, we solve the long standing open problem on exact dimensionality of self-affine measures on the plane. We show that every self-affine measure on the plane is exact dimensional regardless of the choice of the defining iterated function system. In higher dimensions, under certain assumptions, we prove that self-affine and quasi self-affine measures are exact dimensional. In both cases, the measures satisfy the Ledrappier-Young formula. peerReviewed
On a Robin (p,q)-equation with a logistic reaction
2019
We consider a nonlinear nonhomogeneous Robin equation driven by the sum of a \(p\)-Laplacian and of a \(q\)-Laplacian (\((p,q)\)-equation) plus an indefinite potential term and a parametric reaction of logistic type (superdiffusive case). We prove a bifurcation-type result describing the changes in the set of positive solutions as the parameter \(\lambda \gt 0\) varies. Also, we show that for every admissible parameter \(\lambda \gt 0\), the problem admits a smallest positive solution.
