L'utilisation des etudiants comme operateurs dans les enquetes de terrain : les avantages et les limites
Get PDFUtilizarea studenţilor ca operatori în anchetele de teren : avantaje şi limite. Deoarece studiile de teren au căpătat o importanţă crescută în cercetarea de piaţă şi academică în România, studiul de faţă îşi propune evidenţierea şi evaluarea cauzal-explicativa a surselor de eroare introduse de operatorii-studenţi. Aceasta cu atât mai mult, cu cât în multe cercetări academice, şi nu numai, sunt utilizaţi ca operatori de teren studenţii.Evaluarea impactului operatorilor asupra eficienţei anchetei s-a bazat pe prelucrarea datelor unui studiu privind sentimentul de vulnerabilitate seismică a populaţiei oraşului Bucureşti, realizat în anii 2001–2002.Au fost sistemetizate patru tipuri de erori (omisiuni şi falsuri) în acord cu categoriile de date ale instrumentului: erori de tip 1 - omisiuni/falsuri la datele de identificare ale operatorului), erori de tip 2 - omisiuni/falsuri la datele de „paşaport” ale subiectului cercetat, erori tip 3 - omisiuni la itemii care vizau obiectivul 1 al cercetării, erori de tip 4 - omisiuni la itemii care vizau obiectivul 2 al cercetării.Datele arată că echipele de fete au rezultate superioare în raport cu echipele mixte şi cu subiecţii care au operat în mod individual, existând mai puţine omisiuni în chestionarea la itemii care vizau obiectivul 2 al cercetării
The foreign subjects from the Romanian extracarpathic provinces in the 19th century-with a special regard on Moldavia
Get PDFThe 18th and 19th centuries represented a period of important changes for Moldavia, changes that occurred at the level of the ethnical structure of the population of this province, first of all because more persons from different ethnical groups established in this area. A part of this people often chose to become citizens of other states, generally of European ones, based on many reasons, the phenomenon amplifying during the 19th century. The presence of these foreign subjects on the territory of Moldavia, but also on the territory of other Romanian provinces outside the Carpathians Mountains had some specific features and played an important role in the economic, social and cultural life of these provinces
The territorial distribution of working force in Moldavia, expression of the attractivity of cities
Get PDFDistribuţia teritorială a forţei de muncă în Moldova, expresie a atractivităţii urbane. Articolul îşi propune să analizeze fenomenul de navetism ţinând cont şi de rolul pe care îl joacă oraşele în individualizarea şi dezvoltarea fluxurilor de navetişti. Deplasările zilnice pentru muncă spre centrele economice urbane cunosc oscilaţii în raport cu perioadele de creştere sau declin economic, cu transformările care pot avea loc la nivelul sistemului de aşezări. Articolul de faţă foloseşte datele puse la dispoziţie de recensământul din anul 2002, la nivel de unitate administrativă
Gully erosion within the Racul catchment (Central Moldavian Plateau, Romania)
Get PDFThe Racul catchment is located in the Central Moldavian Plateau, having a total area of 3,990 ha. With the help of aerial photographs and field measurements and observations, 67 gullies were identified, stretching on a 0.29 km2 area (0.7% of the catchment’s total area). The comparative analysis of the information in the topographic maps (1977), aerophotograms (2005, 2009) and topographic levelling (2011) on a representative group of 17 gullies allowed the estimation of some gullying indices, such as gully-head advance and areal gully growth
L’evolution des rapports entre la distribution spatiale de la population et la desserte en voie de communications modernes. Etude de cas - la Moldavie
Get PDFThis study aims to examine the correlations between the quality of transport infrastructure and the evolution of the spatial distribution of population over a long period (1860-2002). It is certified so that after 1948 we can only speak of a true correlation between the two track parameters, the effect of a lack of economic and social modernization of the studied region. In this way only in the last half century has shown, large and rough, the rural exodus and only in recent decades can speak o the manifestation of axial concentration and suburbanization trends. These processes show a continued divergence in the evolution of both population density and average annual growth rate, unlike the period before 1948, marked by a relative homogeneity. From this divergence were born a number of gaps that are consistent, with few exceptions, the spatial distribution of population dynamics in developed countries.

The influence of geomorphologic processes on land use in Vrancea’s Subcarpathians
Get PDFInfluenţa proceselor geomorfologice auspra utilizării terenurilor în Subcarpaţii Vrancei. Aria studiată include teritoriul comunelor Vidra, Valea Sării, Bârseşti, Negrileşti, Tulnici, Vrâncioaia, Năruja, Paltin şi Nereju. Procesele geomorfologice majore au o puternică influenţă asupra utilizării terenurilor, reducând fertilitatea solurilor prin îndepărtarea stratului de humus. Zona studiată poate fi considerată printre cele mai erodate din ţară, factorii explicativi ţinând mai ales de structura geologică şi caracteristicile cuverturii pedologice

Work abroad before, during and after household creation. An exploration of the economic role of work migration
Get PDFThis paper examines the migration practices of Romanians mainly originating from urban areas in the Romanian Moldova region. It reports on the first results of a partly quantitative, partly qualitative research on the relationships between work migration and social reproduction of Romanian citizens. It examines especially how different age-groups motivate their work abroad and how they allocate the income earned abroad. It explores the dynamical nature of a household and seeks after the place of ‘going abroad’ in the creation and maintenance of households
