Temporal changes in pluvial continentality over Oltenia plain

January 31, 2021 /
Alina VLĂDUŢ
Abstract

There are analysed the variability and trends of pluvial continentality over the Oltenia Plain for the period 1961 to 2018. The datasets cover monthly precipitation amounts from seven meteorological stations, based on which there were calculated five specific continentality indices: Vemičs index of precipitation and seasonal precipitation quotients (RShy/RWhy, RWin/RSum, RWin/RSpr, RAut/RSpr). In terms of spatial distribution, continentality generally increases eastwards. The variability of the pluvial continentality was analysed by the mean of ten-year intervals, while linear regression and the non-parametric Mann-Kendall test were used to emphasize any trend present in the datasets. Linear regression did not highlight a significant upward or downward trend, while Mann-Kendall test illustrated a monotonic upward trend all over the analysed region for RAut/RSpr mainly induced by the increase of the precipitation amount during autumn. The results are statistically significant for the eastern and western extremities of the plain.

Soil erosion and landslides in Izvorul Muntelui lake area

January 31, 2021 /
Ioana Monica MUSCALU
Abstract

The basin of Lake Izvorul Muntelui, is located in the Carpathian Flysch, being limited by the slopes that belong to the Ceahlău, Bistriței, Stânișoarei Mountains. Due to the alternation of detrital deposits with different hardness, the slopes around the lake are affected by various forms of degradation, determined either by gravitational processes, such as; landslides, collapses or solifluxions, or processes and denudational phenomena such as: gutters, ravines, torrents. Of these processes, landslides are predominant, because in the petrographic structure of the flysh there are mainly rocks with advanced plasticity in contact with water, especially clays, marne or marny-clayey shale. The most landslides affected localities are: Poiana Teiului, Hangu, Bicaz, where hundreds of such gravitational processes have been identified, the effects of which are the destruction of households, dwellings, household annexes, blocking of communication routes, splitting villages in two parts by the transported and deposited deluvial material, but also the impediment of the traffic on DN 15, its blocking, the interruption of the traffic or its deviation. After the inventory of lands degraded land affected by landslides and the map of soil erosion, a series of amelioration measures were proposedin order to reduce the effects of these geomorphological processes.

Evaluation of degradation status for three caves in Romania

January 31, 2021 /
Ștefan NEGREANU
Abstract

Cave ecosystem research has known a growing interest in the last years. Nonetheless there is more to be found out about underground world of caves. The difficulty of access and rapid change of conditions that might occur in many cases, among other factors make the survey of this kind of environment a hard task to accomplish. This paper applies on three caves from Romania, the attempts made by other authors in assessing the degree of cave environment degradation. Method used combines characteristics of both subterranean and supraterranen domains associated to caves.

Costela IORDACHE
Abstract

The current paper aims at presenting the demographic elements of the Roma community within Dolj county, according to the statistical data from 2011 census. The main hypothesis of the study was that Roma form a national minority with a peculiar demographic behaviour, different from that of other minorities. The analysis of the demographic characteristics of the Roma community within Dolj county focused on the following elements: territorial distribution, population growth during the 1992-2011 period, the share of Roma persons in the total population, the age and gender structure, economic activities, education level and religious adherence.

ICTs and the new players in the digital economy in the city of Yaoundé (Cameroon): the case of the maintenance of technological and electronic equipment

January 31, 2021 /
Clotaire NDZIE SOUGA Gilbert BAMBOYE FONDZE
Abstract

Like most African countries, Cameroon benefits from the advantages of the use of Information and Communication Technologies. Faced with the emergence of the digital economy that influences all of contemporary society, there is the emergence and high consumption of computer, technological and electronic equipment by urban and rural populations in Cameroon. In Yaoundé, this situation is observed in the popularisation of the mobile phone, the creation of start-ups, multimedia centres and especially the use of computers of all kinds. This digital economy is at the origin of the emergence of new actors whose main role is the maintenance of this increasingly sophisticated technological equipment. In the city of Yaoundé, these actors work daily in centres or structures that ensure the maintenance of the said devices in case of breakdown or mishandling. This research analyses the socio-economic and spatial implications of handling these technological equipments in Yaoundé. It is based on ab survey of 203 Yaoundé’s technology and electronics repair workshops conducted between 2014 and 2017, as well as direct interviews with 192 customers who solicited and obtained the services of these micro-enterprises. Thus, the implantations of the micro-computer and technological maintenance companies in this city have considerable socio-economic and spatial consequences through the creation of jobs and incomes as well as the undeniable strategies of the actors both in the conquest of the market and the occupation of urban space and the territory of Yaoundé.

Changes in the spatial pattern of permanent immigration in post-communist Romania – an overview

January 31, 2021 /
Cristina ȘOȘEA Liliana POPESCU
Abstract

Current migration processes require special assessment and attention due to their complexity and multiple socio-economic implications. The forms of international migration have only recently intensified in Romania due to the barriers imposed by the former communist regime, but their influence on population dynamics is certainly significant and the effects on national economy and demographic vitality of the country are undeniable. Although mainly recognized as an emigration country at the beginning of the post-communist period, Romania is recently going through a period of accentuated intensification of immigrant flows.
Starting with the 1990s, the share of immigrant flows in the net international migration balance has changed in dynamics, motivations, structure, specialization, forms, spatial intensity and consequences etc. This research presents a territorialized analysis of immigration to Romania in the period comprised between 1990-2017, which presents a high mediatic and scientific interest, given the volume and importance of the phenomenon.
