Regional Formation and Development Studies

The article reveals the content of individual and differentiated approaches to teaching of primary school children with mental development disorders. Learning objectives and the ways to achieve them. The forms of activity organization are determined to develop children’s abilities to acquire and apply skills. Appropriateness of programmed learning as a part of the differentiated approach is analyzed to educate children with mental development disorders. Practical aspects of individual approach and differentiation are presented with the example of teaching of primary school-children at a special needs school.

The research analyses the beach litter monitoring programme in Latvia and provides suggestions for its improvement seeking to provide necessary information for effective marine litter management on the Latvian coastline of the Baltic Sea. The beach litter monitoring programme has been enacted since 2012 by NGO “FEE Latvia” and current research has been focused on the situation assessment and particularly provides analyses on a number and distribution of the surveyed beaches, the frequency and timing of the monitoring, litter classification and counting methodology, as well as the possible programme development using the NGO work based on the citizen science approach. The results allow to elaborate several suggestions on how to improve the programme in order to provide lacking information in Latvia on the implementation of the Marine Strategy Framework directive of European Union, and to advise local municipalities in their coastal waste management practices. The suggestions include the increasing number of monitoring sites, a prioritization of the EU Master list classification protocol and an increase of sites with higher frequency of monitoring (3 times per year). Moreover, in the conducted public survey, the beach visitors demonstrated good understanding of marine litter and highly prioritized the issue. The increased interest can add public participation to further development of this applied here citizen science approach.

Physical and chemical parameters were measured in a mostly freshwater estuarine lagoon in the SE Baltic. Present paper demonstrates an attempt to trace the sources and analyse the seasonal and spatial patterns of distribution of POC, DIC and DOC in the Curonian lagoon mostly by the isotopic content in different forms of carbon. Samples were collected in 2012-2014 in 9 stations in the Curonian lagoon including riverine and marine input/output stations. Riverine inputs and summarizing outflow to the Baltic sea locations (Nemunas river delta and Klaipeda channel stations were sampled monthly, while POC, DIC and DOC samples in other stations were collected on a seasonal basis. The observed results allow easily differentiate between estuarine and riverine POM samples, while the differences in DOC δ13C content between sampling stations were found to be not statistically reliable. The high biological productivity of the Nemunas river along with the minor contribution of the Baltic Sea inflows to the overall hydrodynamics of the lagoon explain similarity of content between riverine and estuarine material in the spring and autumn. However, the δ13C content of DIC and DOC could serve as indicator of external inputs only in connection with seasonal water residence variations.

The article presents aspects of the cultural function of Nordic Bronze Age hanging vessels, on the basis of their distribution and production in the Baltic Sea region. Depositions with hanging vessels and related objects show for some regions a similar understanding of the right use and ritual knowledge.

The article presents the latest data on ships sunk in Lithuanian territorial waters of the Baltic Sea obtained during archaeological research conducted by the Underwater Archaeology Group of Klaipėda University. The article contains detailed descriptions of the ways these ships were wrecked as found in historical sources from the 14th to the early 20th century, the localisation of newly found remains of wooden ships, data of their study and possibilities for dating them.
