event study analysis
Opis:
The reaction of marginal investors to the announcement of a surprise dividend increase has been measured. Although field research is performed on companies listed on the Warsaw Stock Exchange, the paper has important theoretical implications. Valuation theory gives many clues for the interpretation of changes in dividends. At the start of the literature review, the assumption of the irrelevance of dividends (to investment decisions) is described. This assumption is the basis for up-to-date valuation procedures leading to fundamental and fair market valuation of equity (shares). The paper is designed to verify whether the market value of stock is immune to the surprise announcement of a dividend increase. This study of the effect of a surprise dividend increase gives the chance to partially isolate such an event from dividend changes based on long-term expectations. The result of the research explicitly shows that a surprise dividend increase is on average welcomed by investors (an average abnormal return of 2.24% with an associated p-value of 0.001). Abnormal returns are realized by investors when there is a surprise increase in a dividend payout. The subsample of relatively high increases in a dividend payout enables investors to gain a 3.2% return on average. The results show that valuation models should be revised to take into account a possible impact of dividend changes on investors’ behavior.

Opis:
W 3-letnim doświadczeniu polowym badano wpływ nawożenia różnymi dawkami siarki siarczanowej i elementarnej na zawartość przyswajalnego magnezu w glebie, w dwóch poziomach: 0-40 i 40-80 cm. Dodatkowo badano wpływ nawożenia siarką na zawartość oraz pobranie magnezu przez rośliny: kapustę, cebulę i jęczmień jary, w dwóch fazach rozwoju. Nawożenie dawką 120 kg S·ha-1 spowodowało zmniejszenie zawartości przyswajalnego magnezu w glebie, w poziomie 0-40 i 40-80 cm, oraz magnezu ogółem w kapuście i jęczmieniu w fazie juwenilnej. Działanie siarki na zawartość i pobranie magnezu zależało od gatunku i fazy rozwojowej rośliny. Nawożenie siarką miało, na ogół, niewielki wpływ na zawartość magnezu w roślinach dojrzałych.
In a three-year field experiment the influence of fertilization with different doses of sulphate and elementary sulphur on the content of available magnesium in soil layers at the depths of 0-40 and 40-80 cm was studied. Impact of fertilization with sulphur on the content and uptake of magnesium by plants (cabbage, onion and spring barley in two growth stages) was estimated in the studies. Fertilization with 120 kg S·ha-1 caused decrease in the content of available magnesium in soil at 0-40 and 40-80 cm depth. Decrease of total magnesium content was observed in cabbage and juvenile plants of spring barley. The influence of sulphur fertilization on the content and uptake of magnesium depended on the growth stage of crops. only slight influence of fertilization with sulphur on the content of magnesium in ripe crops was observed.

Opis:
W latach 2000-2002 przeprowadzono 3-letnie doświadczenie polowe, w Byszwaldzie, w pobliżu Lubawy. Eksperyment założono na glebie brunatnej, kwaśnej o składzie granulometrycznym piasku gliniastego mocnego. Celem badań było określenie wpływu wzrastających dawek siarki siarczanowej i elementarnej na zawartość wapnia i wielkość pobrania tego składnika przez kapustę, cebulę i jęczmień jary oraz na zawartość witaminy С i cukrów w kapuście i cebuli. Przez cały okres trwania doświadczenia dawki siarki siarczanowej (S-SO4) i elementarnej (S-S°) wynosiły: S, - 40, S2 - 80 i S3 - 120 kg·ha⁻¹. Roślinami testowanymi były kolejno: kapusta głowiasta, cebula zwyczajna i jęczmień jary. Rośliny badane były w dwóch fazach: juwenilnej i dojrzałości technologicznej. Wpływ siarki na zawartość wapnia w roślinach oraz jego wynos zależał od dawki i formy siarki oraz gatunku i fazy rozwojowej rośliny. Największy wzrost zawartości wapnia w cebuli dojrzalej konsumpcyjnie stwierdzono po zastosowaniu siarki elementarnej w największej dawce oraz siarki siarczanowej w najmniejszej ilości. Udział siarki w nawożeniu wpłynął na zwiększenie zawartości wapnia w ziarnie jęczmienia. Nawożenie siarką nie miało istotnego wpływu na zmiany zawartości wapnia w kapuście w obu fazach rozwoju oraz w jęczmieniu jarym w fazie kłoszenia. Zastosowanie siarki powodowało na ogół obniżenie zawartości witaminy С oraz cukrów prostych i ogółem w kapuście i cebuli w odniesieniu do obiektu z samym NPK
Three years field experiment was carried out at Byszwałd near Lubawa (north-eastern Poland) in years 2000-2002. The experiment was established on brown acid soil of loam granulometic composition. The study determined the? effect of improved doses of sulphate and elementary sulphur on calcium content and uptake by cabbage, onion and spring barley. The content of vitamin С and; sugars in cabbage and onion were also observed. During whole time of experiment the following doses of sulphate (S-S04) and elementary sulphur (S-S°) were applied: S, - 40, S2 - 80 and S3 - 120 kg·ha⁻¹. Tested plants in sequence were: cabbage, onion and spring barley. The plants were examined in two phases: juvenile and technological maturity. The influence of sulphur on content calcium in plants as well as calcium uptake was dependent on doses, form of applied sulphur, species and phase of plant growth. Largest increase of calcium content in matured onion was stated after adding of maximum dose of elementary sulphur and minimum dose of sulphate sulphur. Sulphur fertilization increased the content of calcium in barley grain. The sulphur fertilization did not significantly the calcium content in cabbage at two development phases nor on earing phase of spring barley. Sulphur application as a rule decreased the contents of vitamin C, simple and total sugars in cabbage and onion in comparison to fertilization treatment with NPK only.

Opis:
The density of states for ballistic electrons in the presence of an electric field of almost arbitrary shape is calculated for one, two, and three dimensions using the semiclassical quantization in a finite sample. The semiclassical results are compared with these of the complete quantum treatment for a constant electric field. The case of crossed electric and magnetic fields is also considered and it is demonstrated that in this configuration the density of states exhibits a transition between magnetic and electric types of motion. Implications of this transition for the quantum Hall effect are mentioned.

Opis:
Purpose: Body balance, as one of the coordination abilities,is a desirable variable for basketball players as regards the necessity of efficient responses in constantly changing situations on a basketball court. The aim of this study was to check whether physical activity in the form of running and jumping influences variables characterizing the process of keeping body balance of a basketball player in the standing position. Methods: The research was conducted on 11 young basketball players. The measurements were taken with a Kistler force plate. Apart from commonly registered COP displacements, an additional variable describing the process of keeping body balance by a basketball player was ankle joint stiffness on the basis of which an “Index of Balance–Stiffness” (IB-S) was created. Results: Statistically significant differences were obtained for the maximum COP displacements and ankle joint stiffness between measurements of balance in the standing position before and after the employed movement tasks whereas there were no statistically significant differences for the aforementioned variables describing the process of keeping balance between measurements after running and after jumping. Conclusions: The research results indicate that the employed movement activities brought about significant changes in the process of keeping balance of basketball player in the standing position which, after the run performed, remain on a similar level to the series of jumps being performed. The authors attempted to establish an index based on the stiffness which yields a possibility to perceive each basketball player as an individual person in the process of keeping balance.

Opis:
In this research, a comparative analysis of results of investigations involving different human populations, in terms of a relation between the oral cavity health and the species composition of mouth microbiota is reported. The purpose of this analysis was to identify and assess microorganisms that could cause health complications in patients with neoplasm requiring dental problem-related surgical management. The patients with the oral cancer surgically treated and those without neoplasm were assessed for their oral health: status of teeth, gingiva, periodontium, and occurrence of inflammatory processes. From each patient, microorganisms isolated of periodontium, dental plaque, and dental pocket swabs were identified in wet and stained microscopic preparations; standard microbiology in vitro techniques were also applied to determine the fungal and bacterial strains. The comparative analysis of results of direct microscopic examinations and in vitro cultures assessment indicated significant differences in prevalences of fungi, parasitic oral protozoans and bacteriae in particular patient’s groups. Yeast-like fungi belonging to Candida genus, mostly of C. albicans group, were identified in 93.75% patients with the oral cancer, while in 25% of individuals assessed without neoplasm. E. gingivalis amoebae were only found in 12.5% patients with the serious disease; no trichomonads were detected in all patients analyzed. Among bacteria species, potentially pathogenic Enterobacteriaceae were found in the patients with oral cancer. The pronounced shift in the microbiota species composition in the patients who needed prolonged treatment due to oral cavity cancer, compared to other generally healthy persons has been showed in this analysis.

Opis:
The magnetic studies of temperature and field induced phase transitions were performed on single crystals of HoCo$\text{}_{3}$Ni$\text{}_{2}$ compound. The rotational-type spin reorientation was found between T$\text{}_{SR1}$ = 160 K and T$\text{}_{SR2}$ = 200 K. In the vicinity of T$\text{}_{SR1}$ two different field induced transitions were observed: the first order moment reorientation type transition in the basal plane and the spin reorientation from the easy plane to the c-axis with simultaneous increase in spontaneous magnetization. The intersublattice molecular field coefficient as well as the magnetization anisotropy of Ho sublattice were determined. The observed magnetic behaviour was analysed within the framework of the spin-reorientation model, taking into account the change of the intrinsic states of rare-earth ions caused by their huge anisotropy energy. The thermal variation of the anisotropy constants of the studied compound is also presented.

Opis:
The retrospective analysis of data on oral cavity clinical status in relation to microbiota species composition is presented. The research regards patients of different age, with and without congenital malformation, pretreatment assessed for occurrence of pathological changes in the masticatory system. Samples of the swabs collected from each patient (from dental plaque, periodontium and dental pockets) were used for identification of oral protozoans in wet slides and stained preparations; additionally, transmission electron microscope examination was performed. The material was used for in vitro cultures to identify bacteria strains. Clinically, intensity of tissue deteriorations was higher in patients with a congenital disease. Alive Trichomonas tenax and Entamoeba gingivalis, species with confirmed pathogenic impact on oral cavity and neighboring structures, were detected with higher prevalence in older patients. Enterococci, Staphylococcus aureus, various Enterobacteriaceae were more frequently detected in patients with somatic and mental retardations; in mouths of those patients, Klebsiella pneumonia and Pseudomonas aeruginosa opportunistic strains occurred. Masticatory system abnormalities favor colonization of oral cavity by exogenous species and dissemination of infections, especially dangerous for patients with congenital diseases. Oral microbiota assessment and preventive measures may be helpful to avoid subsequent peri-surgery complications.

Opis:
The effect of W92/72 transgenic flax seeds taken from a variety of Linola on the production of SCFA, ammonia and methane by bacteria inhabiting rabbit caecum was studied. The in vitro method was used where caecal contents from rabbits was incubated with W92/72 transgenic or Linola flax seeds, or without any additives (control samples).The total concentration of SCFA was higher in samples with the addition of flax seeds than in the control samples. The increase in concentrations of acetic, propionic and butyric acids was the highest in samples with Linola seeds added. A higher percentage of propionic and butyric acids was observed in the contents incubated with addition of flax seeds as compared to the control samples. This increase was the result of a percentage decrease in acetic acid. No differences were observed in the concentration of ammonia between fermented samples. Moreover, the addition of flax seeds resulted in slight decrease of pH in incubated samples. In gas samples, the methane level was higher in samples with flax seeds added, although the highest level was found in samples with transgenic seeds.In addition, gas pressure was significantly higher in samples with flax seeds added as compared to control samples, and this may indicate a higher intensity of microbiological fermentation processes. These studies suggest that neither Linola nor W92/72 flax seeds have any unfavorable effect on the caecal microflora activity of rabbits. A beneficial influence of flax seeds on the microbiological fermentation process in rabbit caecum was observed, based on an increase in percentage ratio of propionic acid in samples with flax seeds added.
