Scale Of Diversification Research Articles

Diversification of services at the central libraries of RF constituent territories in the circumstances of service economy

The study goal is to specify the nomenclature of services types as presented at the library official websites. The authors characterize the library services as the subject of multi-aspect analysis and evaluation. They emphasize that the concept “library services” and “services by libraries” are not identical. The service economy affects diversification of services provided by the libraries. The authors complement the publications theoretical analysis with the findings of the largescale empirical study of services represented at the official websites of 77 central libraries of the RF constituent units (republican, regional territorial universal scientific libraries). The scale of diversification is demonstrated. The authors argue that the libraries have to undertake some unusual activities and to provide services foreign to their nature and social mission. The findings of the study demonstrate that services production in the libraries corresponds to 30 different types of professional activities. Many services provided by the libraries call for other than library, information, or bibliographic competences. Therefore, services quality assessment is needed; certification and licensing of the libraries providing them may be needed. The authors conclude that diversification as manifested in services inappropriate to the libraries is forced by the transfer to the market economy, development of service economy, and the focus on service-oriented government.

Zarządzanie majątkiem jednostek gospodarczych o różnym profilu produkcji

Celem niniejszego opracowania jest próba ukazania zakresu zarzadzania majątkiem podmiotów gospodarczych o różnym profilu produkcji. Materiałem badawczym były dane o gospodarstwach charakteryzujących się zróżnicowanym profilem produkcji, które w 2017 roku prowadziły rachunkowość rolną w ramach polskiego FADN. Poszczególne wielkości ukazano w przeliczeniu na jedno gospodarstwo w zł. Skalę zróżnicowania analizowano w podziale na osiem typów rolniczych. Majątek gospodarstwa przedstawiono w podziale na aktywa trwałe i obrotowe. Rozpatrywanym parametrem oceny sprawności zarządzania majątkiem była efektywność wykorzystania zasobów. Najwyższym poziomem produktywności i dochodowości kapitału odznaczały się gospodarstwa drobiarskie i ogrodnicze. Wysokim poziomem produktywności i dochodowości pracy odznaczały się gospodarstwa nastawione na chów krów mlecznych i trzody chlewnej. O jakości zarządzania podmiotu gospodarczego informuje także jego kondycja finansowa. Jej syntetycznym wskaźnikiem jest rentowność kapitału własnego ROE. Wśród analizowanych gospodarstw najwyższą dodatnią rentownością kapitału własnego odznaczały się gospodarstwa drobiarskie. Wielkość wskaźnika ROE wynosiła tutaj 14,74%. Na nieco niższym poziomie kształtował się on w gospodarstwach, gdzie dominującą produkcją był chów krów mlecznych i trzody chlewnej. Dodatnią rentownością odznaczały się jeszcze gospodarstwa ogrodnicze.

Efektywność wykorzystania zasobów w różnych typach gospodarstwach

Typ rolniczy stanowi jedno z kryteriów używanych dla charakteryzowania gospodarstwa rolnego w UE. Celem niniejszego opracowania jest próba ukazania zakresu efektywności wykorzystania zasobów produkcyjnych w różnych typach gospodarstw. Do oceny efektywności gospodarowania w poszczególnych typach gospodarstw posłużono się produktywnością i dochodowością ziemi, pracy i kapitału. Poszczególne wielkości ukazano w przeliczeniu na jedno gospodarstwo w zł. Skalę zróżnicowania przedstawiono w ujęciu procentowym. Przeprowadzona analiza wykazała, iż intensywna produkcja prowadzona w gospodarstwach drobiarskich i ogrodniczych sprawiała, że to właśnie one osiągnęły w 2016 roku najwyższą produktywność i dochodowość ziemi i kapitału.

Animating and exploring phylogenies with fibre plots.

Despite the progress that has been made in many other aspects of data visualisation, phylogenies are still represented in much the same way as they first were by Darwin. In this brief essay, I give a short review of what I consider to be some recent major advances, and outline a new kind of phylogenetic visualisation. This new graphic, the fibre plot, uses the metaphor of sections through a tree to describe change in a phylogeny. I suggest it is a useful tool in gaining an rapid overview of the timing and scale of diversification in large phylogenies.

Diversification: Economies of scale of HR and healthcare indent for benchmarking

In recent years, hospitals explore new segments in their service models to penetrate market strategies: they pursue various service models as guiding principle to pave way for growth; even(though) they do not promise desired outcomes. This paper addresses the issue of economies of scale of diversification and its related challenges to human resources for benchmarking. The study explores – to what extent service models diversification tactics increase the growth of a hospital. In a small empirical study of the Sarvodya Hospital and Research Centre, Haryana, India, the study demonstrates that the service diversification points out that the creation of a cost-effective service models desires the exploration and maturity of expertise and reasonable experience in organizational re-structuring.

The Impact of Mutation and Gene Conversion on the Local Diversification of Antigen Genes in African Trypanosomes

Patterns of genetic diversity in parasite antigen gene families hold important information about their potential to generate antigenic variation within and between hosts. The evolution of such gene families is typically driven by gene duplication, followed by point mutation and gene conversion. There is great interest in estimating the rates of these processes from molecular sequences for understanding the evolution of the pathogen and its significance for infection processes. In this study, a series of models are constructed to investigate hypotheses about the nucleotide diversity patterns between closely related gene sequences from the antigen gene archive of the African trypanosome, the protozoan parasite causative of human sleeping sickness in Equatorial Africa. We use a hidden Markov model approach to identify two scales of diversification: clustering of sequence mismatches, a putative indicator of gene conversion events with other lower-identity donor genes in the archive, and at a sparser scale, isolated mismatches, likely arising from independent point mutations. In addition to quantifying the respective probabilities of occurrence of these two processes, our approach yields estimates for the gene conversion tract length distribution and the average diversity contributed locally by conversion events. Model fitting is conducted using a Bayesian framework. We find that diversifying gene conversion events with lower-identity partners occur at least five times less frequently than point mutations on variant surface glycoprotein (VSG) pairs, and the average imported conversion tract is between 14 and 25 nucleotides long. However, because of the high diversity introduced by gene conversion, the two processes have almost equal impact on the per-nucleotide rate of sequence diversification between VSG subfamily members. We are able to disentangle the most likely locations of point mutations and conversions on each aligned gene pair.
