Regional Development and Private Consumption Structure in Latvia

AbstractThe matter of the territories’ facilitation development in Latvia's regional economics is significant under the EU conditions. In order to compare the regional economic development level it is suggested to use the relation between consumer income growth and changes in expenditures on food and non-alcoholic beverages. The average income level of inhabitants in Riga region is higher than in other Latvian regions, which consequently demonstrates lower proportion of food expenditure in private consumption structure. The results of the analysis of covariance demonstrate that, first, Latvian regional level of economic development is significantly different from Latvia's average development level and, second, there is still a gap among living conditions in Latvia's regions

Aportes para una traducción regional de la categoría de régimen de bienestar. Una mirada desde el caso argentino

The category of welfare regime has been applied in critical contributions to the study of protection schemes in Latin American countries. This article reviews early debates in which this category was employed in the European context, and the transition to its application by Latin American researchers to study the cases of their own countries. The manner in which the perspective of welfare regimes and related conceptual tools were adapted to propose regional and local analyses of Latin America is also discussed. Starting with an analysis of how the Argentine case was understood, the approaches that characterized the regimes of the region as hybrid, incomplete, or embryonic are then analyzed and some possible vectors for a critical update are proposed. The theoretical review takes into account the considerable existing bibliography on Latin American welfare regimes.La categoría de régimen de bienestar ha sido aplicada con aportes críticos para estudiar los esquemas de protección en los países de América Latina. En el artículo se recuperan los debates que marcaron una primera etapa de movilización de la categoría en el contexto europeo y la traducción que se hizo desde espacios de investigación de los países latinoamericanos para el estudio de los casos propios. Se problematiza cómo la perspectiva de los regímenes de bienestar y las herramientas conceptuales vinculadasfueron adaptadas para proponer análisis regionales y locales sobre América Latina. A partir de una consideración sobre cómo fue leído el caso argentino, se plantea una discusión con las tradiciones que han caracterizado a los regímenes de la región como «híbridos», «incompletos» o «embrionarios», y se proponen algunos vectores posibles para una actualización crítica de esas lecturas.

Re-discovering Aurelio Peccei's contribution to Futures Studies

AbstractThis work aims to enhance the contribution of Aurelio Peccei to Futures Studies and its unaltered relevance in the light of the world's current scientific issues. Peccei's contribution in Futures Studies is often identified with his propulsive role in the birth of the Club of Rome (1968) and in the promotion of the report "The Limits to Growth" (1972). Although this would be enough to make him a central figure in the history of Futures Studies, his whole intellectual journey is worth emphasizing. This work focuses on the "epistemic impact" of Peccei in the field research on possible futures. Peccei not only argued the fundamental need to translate complexity into a forecasting model: as an ante litteram anticipator, he dedicated his life to seek a development model respecting both the human tendency towards constant evolution and biosphere. A theoretical impact that allowed many fundamental UN initiatives—from the 1987 Report of the World Commission on Environment and Development to the 2015 Report on Sustainable Development Goals (SDGs)—and also helped the development of a forward-looking social research

Inbreeding evaluation in Latvian local cattle breeds

Submitted 2020-06-26 | Accepted 2020-08-18 | Available 2020-12-01https://doi.org/10.15414/afz.2020.23.mi-fpap.52-57In this study, inbreeding and effective population size of the Latvian gene conservation cattle breeds Latvian Brown (LB) and Latvian Blue (LZ) were analysed. The study was based on the pedigree data of 319 LB and 712 LZ cows that were alive at the time of data selection. The inbreeding level in LB and LZ has been increasing during the last decade and at the end of the year 2019, it was 2.61% and 5.20% for LB and LZ, respectively. The average increase of inbreeding from 2010 to 2019 was 1.80% for LB and 2.26% for LZ. The proportions of inbred animals with an inbreeding level greater than 10% were 0.60% and 2.14% in LB and LZ, respectively. Effective population size based on the rate of inbreeding decreased and was close or within the minimum range of recommended effective population size. The current study demonstrates that the inbreeding has increased, and the effective population size decreased in both populations. Therefore, the breeding organizations have to monitor and control the rate of inbreeding in LB and LZ populations over time.Keywords: inbreeding, Latvian Brown, Latvian Blue, native breedReferencesAddo, S., Schäler, J., Hinrichs, D. and Thaller, G.

Longevity and milk production efficiency of Latvian local breeds during last decades

The aim of the study was to analyse the longevity and the amount of energy-corrected milk (ECM) per day of local dairy cattle breeds Latvian Brown (LB) and Latvian Blue (LZ). The study was based on the data of LB genetic resources (LB) 1770 and LZ 921 cows, which were born from January 1st, 2000 till December 31st year 2015. Milk productivity and longevity of the LB and LZ cows were analysed by birth year periods: 2000–2005, 2006–2010 and 2011–2015. LZ culled cows lifespan was in average 2,762.8 ± 55.14 days, or 7.6 years and it was significantly higher than for LB. The average lifespan of LB culling cows was 6.7 years. There are cows which had closed 7–12 lactations. On average, cows’ lifespan decreased during analysed period. In general, LZ cows are characterized by higher length of productive life and milking days. LZ cows produced more EC milk during their productive life; however, they had the lower milking day ECM productivity than LB cows

On Reliability of Dynamic Addressing Routing Protocols in Mobile Ad Hoc Networks

In this paper, a reliability analysis is carried out to state a performance comparison between two recently proposed proactive routing algorithms. These protocols are able to scale in ad hoc and sensor networks by resorting to dynamic addressing, to face with the topology variability, which is typical of ad hoc, and sensor networks. Numerical simulations are also carried out to corroborate the results of the analysis.Comment: Proc. of WRECOM '07: Wireless Rural and Emergency Communications Conference, Roma (Italy), October 200

A Reliability-based Framework for Multi-path Routing Analysis in Mobile Ad-Hoc Networks

Unlike traditional routing procedures that, at the best, single out a unique route, multi-path routing protocols discover proactively several alternative routes. It has been recognized that multi-path routing can be more efficient than traditional one mainly for mobile ad hoc networks, where route failure events are frequent. Most studies in the area of multi-path routing focus on heuristic methods, and the performances of these strategies are commonly evaluated by numerical simulations. The need of a theoretical analysis motivates such a paper, which proposes to resort to the terminal-pair routing reliability as performance metric. This metric allows one to assess the performance gain due to the availability of route diversity. By resorting to graph theory, we propose an analytical framework to evaluate the tolerance of multi-path route discovery processes against route failures for mobile ad hoc networks. Moreover, we derive a useful bound to easily estimate the performance improvements achieved by multi-path routing with respect to any traditional routing protocol. Finally, numerical simulation results show the effectiveness of this performance analysis.Comment: To appear on IJCNDS: International Journal of Communication Networks and Distributed System

Genetic and Phenotypic Parameters for Reproduction Traits of Landrace Sows in Latvia

The aim of this study was to investigate reproduction performance in the 1st and 2nd parity of Latvian Landrace sows, to estimate genetic parameters for reproduction traits, and to determine their genetic correlations with age at the first farrowing (AFF) and weaning to insemination interval (WII) in the Latvian Landrace swine population. Data from 2054 of the 1st parity and 1416 of the 2nd parity sows were collected from 2005 till 2010 and were included in the analysis. Four reproduction traits in the study were analysed: number of piglets born alive (NBA), number of piglets dead (ND), number of piglets weaned per litter (NW) and 21-day litter weight (W21). Genetic parameters were estimated with multi traits animal model using REML procedure. The heritability estimates in the first parity were 0.07, 0.16, 0.36, 0.01 and 0.32 for NBA, NW, W21, AFF and WII, respectively. Between AFF and sows reproduction traits in the first and the second parity unfavourable genetic correlations were found in the present data set. Moderate negative genetic correlation between WII and sows reproduction traits was observed
