We report on longitudinal changes in the system of intensification in an innovative corpus that spans five decades of dialectal speech. Our analyses allow us — for the first time in a British context — to trace the quantitative development in the variable across four generations. Longitudinal analysis across real and apparent time determines the effect of extralinguistic and intralinguistic variables on intensification in Tyneside and tests to what extent real time data corroborates trends reported from previous apparent time analyses. Long-term competition within the variable manifests itself in distinctive developmental trajectories: expansion — both proportionally within the variable as well as across adjectival categories — tends to follow one of three types of patterns, exemplified, respectively, by really, so and dead. Variant retraction, however, follows only one schema. Importantly, numerical decline in the system does not necessarily go hand in hand with a reduction in breadth of application.

The dissertation is a study of the service industries in the United States during the period 1839 through 1899. The primary purpose of the study is to provide three series relating to the quantitative development of the sector. These series—value-added, gainful workers, and capital stock—provide benchmark estimates at decade intervals centered on census years. Series are presented for the aggregate sector; the major components, final and intermediate services; and eight industries. These eight industries, defined as the service sector, are trade, transportation and public utilities, finance and insurance, professional services, personal services, government, education, and the independent hand trades.

The technogenic transformation of the ecosystem of the southeast part of Luga Bay water area (the second bay of the Baltic Sea) where Ust-Luga commercial seaport situated was determined by longstanding dredging, dumping and other types of anthropogenic impact. The development of phytoplankton as the main primary production former and the base of food reserve for aquatic biological resources was investigated during the monitoring of aquatic biological resources of the Luga Bay which was held due to the seaport construction. The investigation of phytoplankton content and development took part in the main seasons of the ice-free period of 2005–2018 in the water areas of dredging, damping, and adjacent areas. The maximum values of the phytoplankton abundance and biomass were detected in spring. The main part of biomass was formed by diatoms and dinoflagellates. The summer biomass mainly was lower than in spring and the proportion of cyanoprokaryotes (in some years also cryptophytes and green) increased. In autumn the biomass decreasing was continued, cyanoprokaryotes and cryptomonads dominated. The quantitative indicators of phytoplankton development were varied from year to year in all seasons of 2005–2018 but they kept in frames of values which previously observed for the water area of the Luga Bay. The influence of the Gulf of Finland water warming on phytoplankton development was not traced. The certain differences between the quantitative development and composition of the dominant phytoplankton complex on the water areas of dredging, damping, and adjacent areas weren’t observed. The average phytoplankton biomass for the ice-free period in the most part of years corresponds to the mesotrophic state of the Luga Bay water area. There was not a significant impact of dredging and dumping on the phytoplankton of the Luga Bay which indicates the stable state of its ecosystem primary producer and the preservation of the productional resource of the fish food base.

Lessepsian invader Anadara kagoshimensis is one of the important elements in the adaptive transformation of the Black sea shelf ecosystem in the second half of the XX century. The aim of the work is to analyse the Black Sea spatial and temporal colonization by this species according to the benthic database of Benthos Ecology Department of IMBR RAS (for the Crimean coasts) and literary sources for the whole Black Sea basin. The phases of this process are considered. A 10-year latency period followed after the first detection anadara in 1968 at Caucasian shelf. The main wave of anadara colonization in the Black Sea covered the Western and Eastern parts of the sea and fall within the period from second half of 1970s to 1980s. During that time period the extended development of A. kagoshimensis lead to forming own reproductive potential for next steps of expansion of this species to Anatolian and Crimean coasts in 1990s. About 20–25 years delay in detection of introduced species at the Northern and Southern parts of the Black Sea shelf, in presence at the Western and Eastern parts, could be an evidence of existing hydrological barrier between far distant nearshore areas of the Black Sea shelf. The reasons of the fluctuations in development of this species settlements are discussed. The phenomenon of introduction and mass development of A. kagoshimensis in the Black Sea during its the “most demand” period as a consumer of excess amount of organic matter, in conditions of eutrophication’s peak in the Black Sea basin at the end of 1980s – the beginning of 1990s is marked. Estuarine areas of the Black Sea shelf enriched by organic matter are the most favourable conditions for the mass development of this species. This quantitative rising is due to wide ecological plasticity and stress tolerance of A. kagoshimensis, which are determined by its physiological and biochemical adaptations to a hypoxic conditions often appearing during eutrophication. Based on parameters of abundance and biomass the actual implementation of A. kagoshimensis biotic potential in the Black Sea is revealed at least within Eastern and Western areas of the shelf, where peaks of its quantitative development is already passed in previous years. This conclusion for the Crimean sector is not obvious because of more recent invasion by anadara of this region. A decrease and stabilization of A. kagoshimensis development, with the exception of local zones near organic ”pollution” sources should be expected under maintaining the tendency of the basin deeutrophication.

Partly by design, partly by coincidence the twelve months from September 1969 to September 1970 saw an “explosion” of reports about development problems. This article is particularly concerned with one of these, Sir Robert Jackson's A Study of the Capacity of the United Nations Development System. While the United Nations Development Program (UNDP) covers only a minor percentage of total assistance extended to less developed countries, its significance reaches beyond its quantitative development impact It has become the single most important United Nations cooperative effort and, more generally, represents an unprecedented example of intergovernmental and interorganizational cooperation.
