Analiza wskaźnikowa jako metoda oceny skuteczności audytu wewnętrznego w racjonalizowaniu gospodarki finansowej jednostek samorządu terytorialnego
2016
Gospodarowanie finansami samorządowymi jest procesem decyzyjnym, którego ważnym elementem staje się informacja. Aby decyzje były racjonalne, nie mogą być przypadkowe i podejmowane w sposób intuicyjny. Powinny opierać się na wiarygodnych i odpowiednio przetworzonych informacjach. Jednym z narzędzi oceny skuteczności działania JST jest analiza ekonomiczna, a szczególnie analiza wskaźnikowa. Z kolei audyt wewnętrzny jest działalnością niezależną i obiektywną, której celem jest wspieranie kierownika jednostki w realizacji celów i zadań przez systematyczną ocenę kontroli zarządczej oraz czynności doradcze. W dużej mierze audyt wewnętrzny jest postrzegany jako narzędzie zarządzania, podczas gdy j…
Data from: Daphnia females adjust sex allocation in response to current sex ratio and density
2019
Cyclical parthenogenesis presents an interesting challenge for the study of sex allocation, as individuals’ allocation decisions involve both the choice between sexual and asexual reproduction, and the choice between sons and daughters. Male production is therefore expected to depend on ecological and evolutionary drivers of overall investment in sex, and those influencing male reproductive value during sexual periods. We manipulated experimental populations, and made repeated observations of natural populations over their growing season, to disentangle effects of population density and the timing of sex from effects of adult sex ratio on sex allocation in cyclically parthenogenetic Daphnia…
An IPMSM torque/weight and torque/moment of inertia ratio optimization
2014
In this paper, a torque/weight and torque/moment of inertia ratio optimization procedure for interior permanent magnet syncronous motors (IPMSMs) is presented. More in detail, a performance comparison between several IPMSM rotor structures has been carried out in order to determine the optimum geometry that can maximize the torque/weight and torque/moment of inertia ratios. A commercial motor, with known electrical and mechanical characteristics, has been taken as reference. Its rotor structure has been modified several times, obtaining different rotor geometries and, therefore, many IPMSM models with different electrical and mechanical characteristics. The finite element method (FEM) analy…
Measuring Performance in the Luxury Industry: Is there a Difference in Performance Between the top and Bottom Players in the Industry?
2021
Abstract This paper presents a methodology that consists of a Z-score function applied on a set of indicators for the luxury industry and then standardized to obtain a ranking of the companies on a scale between 10 and 100. To measure the performance for the top 5 LVMH, Estee Lauder, Richemont, Kering, Essilor Luxottica, and bottom 5 Aeffe, Tribhovandas, Van de Velde, Mulberry, Trinity companies (based on Deloitte global ranking in 2019) in the luxury industry and to unveil which are the performance drivers. By applying this methodology it can be made a comparison in performance between the top and the bottom companies in the luxury industry. The performance score is calculated for ten year…
Stable carbon and oxygen isotope fractionation in bivalve (Placopecten magellanicus) larval aragonite
2008
Abstract The relationship between stable isotope composition (δ13C and δ18O) in seawater and in larval shell aragonite of the sea scallop, Placopecten magellanicus, was investigated in a controlled experiment to determine whether isotopes in larval shell aragonite can be used as a reliable proxy for environmental conditions. The linear relationship between δ13CDIC and δ13Caragonite (r2 = 0.97, p δ 13 C DIC = 1.15 ( ± 0.05 ) ∗ δ 13 C aragonite - 0.85 ( ± 0.04 ) The relationship between δ13CDIC and δ13Caragonite described for P. magellanicus resulted in larval shell aragonite that was depleted on average by 1.82‰ (SD = 0.22‰, range = 1.1–2.1‰) from predicted equilibrium values based on the r…
The Use of Stable Isotope Ratio Analysis to Trace European Sea Bass (D. labrax) Originating from Different Farming Systems
2020
This study aimed to determine whether isotopic ratio mass spectrometry (IRMS) can discriminate farmed European sea bass according to different farming systems and geographic origins. Dicentrarchus labrax of commercial size from three different rearing systems (concrete tank inland, sea cages, and extensive methods in valleys or salt works) were collected at the trading period (autumn&ndash
