Opis:
Chinese fir [Cunninghamia lanceolata (Lamb.) Hook] is a fast-growing tree species that is widely planted for timber production in southern China. Many high-quality breeding systems for Chinese fir have been developed using genetic methods. Here, we systematically review progress in increasing Chinese fir timber volumes per unit forest area in China, using genetic methods. We comprehensively assess the objec- tives, strategies, and primary accomplishments of the first to fourth generations of a Chinese fir breeding program. Furthermore, we propose a genetic improvement program and protocol for Chinese fir, and out- line several recommendations with respect to the main challenges associated with using genetic methods to increase timber yields. Finally, we present a series of proposals to increase Chinese fir timber production in China. This review offers insight into genetic improvements that have increased timber volumes of Chi- nese fir over four generations of breeding, and provides direction for future genetic improvements to wood properties.

Opis:
Research into the phraseological component of dialects in different Ukrainian areas is especially relevant due to the fact that during the last decade the phraseology of dialects has been studied very intensively, despite all the difficulties connected with collecting dialect material and the unrefined methods of their researching. The article is devoted to the structural/semantic description of phraseological units with phytomyn components, which make up the phraseologic/semantic line “unclever, stupid”. The source for this research was material from dictionaries, phrasal dictionaries, and from collections of modern words from three dialects of the Ukrainian language. Analysis of phraseological units and their components in space allowed for the determination of either non-fixed phrases or the absence of their expected components, the firmness of different dialectal phenomena, and system phenomena within phraseology.

Opis:
Domain estimates are typically obtained using calibration estimators that are direct or modified direct. They are direct if they strictly use data within the domain of interest. They are modified direct if they use both data within and outside the domain of interest. An alternative way of producing these estimates is through small area procedures. In this article, we compare the performance of these two approaches via a simulation. The population is generated using a hierarchical model that includes both area effects and unit level random errors. The population is made up of mutually exclusive domains of different sizes, ranging from a small number of units to a large number of units. We select many independent simple random samples of fixed size from the population and compute various estimates for each sample using the available auxiliary information. The estimates computed for the simulation included the Horvitz-Thompson estimator, the synthetic estimator (indirect estimate), calibration estimators, and unit level based estimators (small area estimate). The performance of these estimators is summarized based on their design- based properties

Opis:
Recent discoveries of ammonites in the Štramberk Limestone in the type area of their occurrence near the town of Štramberk supplement existing data on the Tithonian age of the limestones. Franconites cf. fascipartitus occurs in the lower part of the Lower Tithonian (Neochetoceras mucronatum Zone). Lemencia ciliata has a zonal character in the upper part of the Lower Tithonian. Richterella richteri is a subzonal species of the upper part of the Lower Tithonian in the Mediterranean and Submediterranean areas (Semiformiceras fallauxi Zone). All of the new discoveries are referable to the faunal associations of the Submediterranean bioprovince, and are in agreement with existing knowledge of it. Sexual dimorphism was seen in the genus Richterella, with the recognition of both macroconchs and microconchs in the type species of Richterella, i.e. R. richteri. The stratigraphic position of these recent ammonite discoveries in the Štramberk Limestone at the Kotouč Quarry does not support the stratigraphy of the limestones based on the distribution of calpionellids, as previously assumed by other authors. The recent collection of ammonites confirms that the Štramberk Limestone belongs to the lower Tithonian and lower Berriasian and also represents the lower Tithonian as a shallow-water facies.

Opis:
Small area estimation (SAE) has seen a rapid growth over the past 10 years or so. Earlier work is covered in the author's book (Rao 2003). The main purpose of this paper is to highlight some new developments in model-based SAE since the publication of the author's book. A large part of the new theory addressed practical issues associated with the model-based approach, and we present some of those methods for area level and unit level models. We also briefly mention some new work on synthetic estimation of area means or totals based on implicit models.

Opis:
Purpose: The purpose of this paper is to present a theory that defi nes the creation of an area that includes many countries, in which there is one, single currency and the countries are characterized by a diversifi ed productivity. That is why the paper shows the importance of labor productivity parity for the creation of an integrating and non-discriminatory currency area and indicates the role of this value in the theory of the exchange rate. Additionally, the paper analyzes the risks arising from joining the eurozone. Methodology: The basic methodology is defi ned by a fundamental analysis of the exchange rate and its relations to labor productivity parity. The author formulates a theory of a currency area that integrates economies with different levels of labor productivity. The methodology is supplemented by calculations and a ranking of countries according to the Q-index. Findings: Listing the member countries and candidate countries of the eurozone according to the labor productivity index has demonstrated that the founding member states are characterized by a Q-index close to 3.30. The countries that are already in the eurozone with an index of less than 2.5 belong to the group where problems are accumulating. Countries that are candidates for the eurozone with an index below 2.0, such as Poland, cannot become member of the eurozone. The principles of creating a currency area can however be modifi ed in such a way that countries with various levels of Q can become members, by developing cooperation that is benefi cial to the socio-economic development. Originality: The labor productivity index Q is a result of elaborating an original concept of the production function that is suitable for the purposes of economic analysis. According to this function the Q-index is equivalent to the category labor share and the variable F corresponds to TFP. The function overcomes the disadvantageous features of econometric models of production identifi ed by Joan Robinson and the obtained results modify the theory of the exchange rate, creating good prospects for general monetary integration.

Opis:
We review main small area estimation methods for the estimation of general nonlinear parameters focusing on FGT family of poverty indicators introduced by Foster, Greer and Thorbecke (1984). In particular, we consider direct estimation, the Fay-Herriot area level model (Fay and Herriot, 1979), the method of Elbers, Lanjouw and Lanjouw (2003) used by the World Bank, the empirical Best/Bayes (EB) method of Molina and Rao (2010) and its extension, the Census EB, and finally the hierarchical Bayes proposal of Molina, Nandram and Rao (2014). We put ourselves in the point of view of a practitioner and discuss, as objectively as possible, the benefits and drawbacks of each method, illustrating some of them through simulation studies.
