Prezentowana publikacja „Wybrane problemy zarządzania i finansów - studia przypadków” zawiera 14 studiów przypadku (case study) z zarządzania i finansów. Studium przypadku jest to opis badanego obiektu (zjawiska, procesów) w określonych warunkach, miejscu i czasie. Współcześnie jedną z głównych metod wykorzystywanych w naukach o zarządzaniu jest właśnie metoda case study, a w USA i Wielkiej Brytanii jest to metoda wręcz dominująca. Polega ona na analizowaniu i omawianiu prawdziwych (lub prawdopodobnych) sytuacji, uczy podejmowania decyzji gospodarczych w konkretnych uwarunkowaniach i konsekwencji tych decyzji dla przedsiębiorstwa. Głównym celem stawianym publikacji jest uzupełnienie luki na rynku wydawniczym w zakresie zwartych pozycji zawierających studia przypadków z obszaru nauk o zarządzaniu i finansach. W literaturze fachowej możemy spotkać się tylko z kilkoma publikacjami o zasięgu ogólnokrajowym, a także z nielicznymi publikacjami wydanymi przez wydawnictwa o zasięgu lokalnym przed prawie dziesięcioma laty.
Zaprezentowane przypadki można pogrupować według problemów, jakich dotyczą. Pierwsza grupa odnosi się do zagadnień zarządzania strategicznego i marketingowego. Kolejne dotyczą zarządzania i rachunkowości w przedsiębiorstwie. Następna grupa omawia problemy zarządzania personelem, a ostatnia koncentruje się na problemach zarządzania miastem, regionem i w administracji publicznej. Autorzy wyrażają przekonanie, że prezentowana publikacja, zawierająca studia przypadków opisujące rzeczywiste sytuacje gospodarcze i przedsiębiorstwa, będzie wykorzystywana w procesie nauczania w wyższych szkołach w Polsce na kierunkach ekonomicznych i zarządzania
Mechanism of rhabdophane-(La) and lanthanite-(La) formation during reduction of bioavailabe nutrients in water based on sem and XRD study
This study presents results of SEM and XRD investigation of products formed after La-rich bentonite application
into water containing PO4 3- and CO3 2- ions. The main product of the investigated reaction with phosphate and carbonate anions is rabdophane-(La) and lanthanite-(La), respectively. Studied material has adaptation in many water reservoirs only for phosphorus ions reduction. Further studies might find application in case of reduction others hazardous ions. They could be precipitated in the same fast and effective way, to other stable, nontoxic mineral phases
Buffer influence on magnetic dead layer, critical current and thermal stability in magnetic tunnel junctions with perpendicular magnetic anisotropy
We present a thorough research on Ta/Ru-based buffers and their influence on
features crucial from the point of view of applications of MTJs, such as
critical switching current and thermal stability. We investigate devices
consisting of buffer/FeCoB/MgO/FeCoB/Ta/Ru multilayers for three different
buffers: Ta 5 / Ru 10 / Ta 3, Ta 5 / Ru 10 / Ta 10 and Ta 5 / Ru 20 / Ta 5 (all
thicknesses in nm). In addition, we study systems with a single FeCoB layer
deposited above as well as below the MgO barrier. The crystallographic texture
and the roughness of the buffers are determined by means of XRD and atomic
force microscopy measurements. Furthermore, we examine the magnetic domain
pattern, the magnetic dead layer thickness and the perpendicular magnetic
anisotropy fields for each sample. Finally, we investigate the effect of the
current induced magnetization switching for nanopillar junctions with lateral
dimensions ranging from 1 {\mu}m down to 140 nm. Buffer Ta 5 / Ru 10 / Ta 3,
which has the thickest dead layer, exhibits a large increase in the thermal
stability factor while featuring a slightly lower critical current density
value when compared to the buffer with the thinnest dead layer Ta 5 / Ru 20 /
Ta 5
EMPA, XRD, and Raman characterization of Ag-Bearing Djurleite from the Lubin mine, Lower Silesia, Poland
The chalcocite group minerals are widely distributed among different hydrothermally affected rocks, the oxidized zone of copper sulfide deposits, or may be even crystalline from supersat-urated volcanic gases. Some of the chalcocite group minerals form the main Cu orebodies. Djurleite (Cu31S16) is a rare member of the chalcocite group, with a very complex structure. The physical and chemical similarities between all members of the group make them almost unidentifiable by macroscopic and microscopic methods. In this study, Ag-bearing djurleite from the Kupferschiefer deposits, Lower Silesia, Poland, is characterized by EMPA (Electron Microprobe Analyses), XRD (X-Ray Diffraction), and Raman spectroscopy. Djurleite from the investigated site has the following general, average chemical formula: Cu30.86Ag0.1Fe0.04S16. The Ag content is up to 0.55 wt.%, while Fe is up to 0.19 wt.%. The presence of djurleite confirms a low-temperature (~90 ◦C), hydrothermal origin of the Cu-Ag deposit in Kupferschiefer, which is consistent with previously studies. Moreover, the authors believe that Ag-rich djurleite may often be mistaken for Ag-rich chalcocite, which used to be one of the main Ag-bearing minerals in the orebody from the Cu-Ag deposit in the Fore-Sudetic Monocline. However, the confirmation of such a statement requires more samples, which should be studied in detail

Serum metabolomics approach to monitor the changes in metabolite profiles following renal transplantation
Systemic metabolic changes after renal transplantation reflect the key processes that are related to graft accommodation. In order to describe and better understand these changes, the 1HNMR based metabolomics approach was used. The changes of 47 metabolites in the serum samples of 19 individuals were interpreted over time with respect to their levels prior to transplantation. Considering the specific repeated measures design of the experiments, data analysis was mainly focused on the multiple analyses of variance (ANOVA) methods such as ANOVA simultaneous component analysis and ANOVA-target projection. We also propose here the combined use of ANOVA and classification and regression trees (ANOVA-CART) under the assumption that a small set of metabolites the binary splits on which may better describe the graft accommodation processes over time. This assumption is very important for developing a medical protocol for evaluating a patient’s health state. The results showed that besides creatinine, which is routinely used to monitor renal activity, the changes in levels of hippurate, mannitol and alanine may be associated with the changes in renal function during the post-transplantation recovery period. Specifically, the level of hippurate (or histidine) is more sensitive to any short-term changes in renal activity than creatinine
The genetic basis of endometriosis and comorbidity with other pain and inflammatory conditions
Endometriosis is a common condition associated with debilitating pelvic pain and infertility. A genome-wide association study meta-analysis, including 60,674 cases and 701,926 controls of European and East Asian descent, identified 42 genome-wide significant loci comprising 49 distinct association signals. Effect sizes were largest for stage 3/4 disease, driven by ovarian endometriosis. Identified signals explained up to 5.01% of disease variance and regulated expression or methylation of genes in endometrium and blood, many of which were associated with pain perception/maintenance (SRP14/BMF, GDAP1, MLLT10, BSN and NGF). We observed significant genetic correlations between endometriosis and 11 pain conditions, including migraine, back and multisite chronic pain (MCP), as well as inflammatory conditions, including asthma and osteoarthritis. Multitrait genetic analyses identified substantial sharing of variants associated with endometriosis and MCP/migraine. Targeted investigations of genetically regulated mechanisms shared between endometriosis and other pain conditions are needed to aid the development of new treatments and facilitate early symptomatic intervention
