Forecasting without Consequence? Evidence on the Properties of Retiring CEOs' Forecasts of Future Earnings
Authors: Cassell Cory A. , Huang Shawn X. , Sanchez Juan Manuel 
Published: June 2013

ABSTRACT:
We investigate whether retiring CEOs engage in opportunistic terminal-year forecasting behavior and the circumstances in which such behavior is likely to be more or less pronounced. Using a within-CEO empirical design, we find that retiring CEOs are more likely to issue forecasts of future earnings, and that they issue such forecasts more frequently in their terminal year relative to other years during their tenure with the firm. Further, retiring CEOs' terminal-year forecasts of future earnings are more likely to convey good news and are more optimistically biased relative to pre-terminal years. Opportunistic terminal-year forecasting behavior is: (1) more pronounced in the presence of higher CEO equity incentives and when discretionary expenditures are cut in the terminal year, and (2) less pronounced in the presence of stronger monitoring mechanisms, such as higher institutional ownership. Collectively, our results provide evidence on a potential implication of the CEO horizon problem that has not been investigated previously.

Authors: Vasarevičius Saulius , Batavičius Tadas 
Published: June 2013

Abstract
Waste management is one of the most relevant problems of environmental protection. Landfills constitute an unavoidable component of the waste management system. The article discusses the problem of landfill odours. Reduction of waste tipping areas and temporary waste covering are the most efficient measures for reducing odours from landfills. The article presents the results of experimental tests on the use of building debris for the reduction of odours from landfills. Tests were performed by applying dynamic olfactometry. Upon covering waste with the building debris layer of 10 cm thickness odour thresholds fell from 51.0 to 79.7% compared with uncovered waste.

Published: June 2013

Abstract
The processing of ombrographic data from 29 meteorological stations of the Czech Hydrometeorological Institute (CHMI), according to the terms of the Universal Soil Loss Equation for calculating long term loss of soil through water erosion, erosion hazard rains and their occurrence have been selected, with their relative amount and erosiveness - R-Factors determined for each month and years. By comparing the value of the time division of the R-Factor in the area of the Czech Republic and in selected areas of the USA it has been demonstrated that this division may be applied in the conditions of the Czech Republic. For the Czech Republic it is recommended to use the average value R = 40 based on the original evaluation.
A numerical investigation of a buoyancy driven flow in a semi-porous cavity: comparative effects of ramped and isothermal wall conditions
Authors: Chandran Pallath , Sacheti Nirmal C. , Singh Ashok K. 
Published: June 2013

Abstract
Steady two-dimensional natural convection taking place in a rectangular cavity, partially filled with an isotropic porous material, has been investigated numerically using an ADI method. It is assumed that one of the vertical walls of the cavity has a ramped temperature distribution. The vorticity-stream function formulation has been used to solve the set of nonlinear partial differential equations governing the flows in the clear region and the adjoining porous region. The effects of Darcy number and Rayleigh number have been discussed in detail.
Validation of transport and friction formulae for upper plane bed by experiments in rectangular pipe
Authors: Matoušek Václav , Krupička Jan , Picek Tomáš 
Published: June 2013

Abstract
The paper describes results of validation of authors' recently proposed formulae for sediment transport and bed friction in the upper plane bed regime using laboratory experiments in a pressurized pipe. Flows of mixture of water and fine to medium ballotini (d50 = 0.18 mm) were observed in a rectangular pipe (51 x 51 mm) with a deposit at the bottom of the pipe. A comparison of test results with transport-formula predictions shows a satisfactory match confirming a good prediction ability of the proposed transport formula at high bed shear. A prediction ability of the friction formulae appears to be less convincing but still reasonable. A joint use of the formulae for transport and friction predicts the delivered concentration of transported sediment within the accuracy range of ± 40 per cent for flows in which transported sediments strongly affect the bed friction, i.e. for flows with delivered concentration of sediment higher than say 3 per cent.
Numerical investigation of solid-liquid slurry flow through an upward-facing step
Authors: Messa Gianandrea Vittorio , Malavasi Stefano 
Published: June 2013

Abstract
The flow of a solid-water mixture through an upward-facing step in a channel is numerically investigated. The effect of expansion ratio, mean solids volume fraction and particle diameter on the velocity field, pressure distribution and solid volume fraction field is studied. Expansion ratios of 0.50 and 0.67, particle diameter of 125 μm and 440 μm and mean solid volume fraction between 0.05 and 0.20 are considered. Particle density is 2465 kg m-3. An Eulerian twofluid model is used to simulate the flow. Due to the lack of experimental data, the model was validated by comparison to other numerical investigations and to experimental data about the horizontal pipe case. Afterwards, it is studied the effect of the above mentioned parameters upon the degree of coupling between the phases and the extension of the disturbance region in the pressure and solid volume fraction fields downstream the step. Parameters of engineering interest, such as the reattachment length and the pressure recovery downstream the enlargement, are investigated.
Heavy-mineral analysis in Polish investigations of Quaternary deposits: a review
Authors: Marcinkowski Bogusław , Mycielska-Dowgiałło Elżbieta 
Published: June 2013

Abstract
The composition of heavy-mineral assemblages is one of the main textural features of sediments because they can have significant value for the interpretation of, among others, their depositional environment, their depositional processes, and their stratigraphic position. Distinctive features of heavy minerals include their resistance to chemical weathering and mechanical abrasion, their habit, and their density. These parameters are the most widely used in the heavy-mineral research of Quaternary deposits in Poland, as well as in such research in other countries conducted by Polish scientists. Several other heavy-mineral parameters can also be used in various types of interpretation. It is discussed whether heavy-mineral analysis is decisive in the evaluation of deposits or whether it plays mainly a role that may support evidence obtained by other types of analysis. The attention is mainly devoted to transparent heavy minerals; the significance of opaque heavy minerals for interpretational purposes is only mentioned.
Heavy-mineral analysis as a tool in tephrochronology, with an example from the La Sal Mountains, Utah, U.S.A.
Authors: Kleber Arno 
Published: June 2013

Abstract
An essentially pure tephra layer on a steep slope in the La Sal Mountains, Utah, U.S.A., is correlated with the 1.65 Ma old Guaje Tephra derived from the Jemez Mountains, New Mexico, U.S.A. The heavy-mineral contents and glass shards in sediments beneath the La Sal tephra layer indicate that tephra constituents are contained in deposits considerably older than the pure layer. This suggests that tephra material may become reworked while retaining its pure character, possibly due to laminar transport or to dislocation in a frozen condition. This raises the need to handle tephrochronological findings with great care.
Heavy–mineral assemblages from fluvial Pleniglacial deposits of the Piotrków Plateau and the Holy Cross Mountains – a comparative study
Authors: Wachecka-Kotkowska Lucyna , Ludwikowska-Kędzia Małgorzata 
Published: June 2013

Abstract
The heavy-mineral assemblages of Pleniglacial fluvial sediments were analysed for two river valleys, viz. the Luciąża River (at Kłudzice Nowe) and the Belnianka River (at Słopiec). These sites, on the Piotrków Plateau and in the Holy Cross Mountains respectively, are located in different morphogenetic zones of Poland that were affected to different degrees by the Middle Polish ice sheets. The study was aimed at determining the kind of processes that modified the heavy-mineral assemblages in the two fluvial sediments, at reconstructing the conditions under which these processes took place, and in how far these processes caused changes in the assemblages. The heavy-mineral associations of the parent material was taken as a starting point; this parent material were the sediments left by the Odranian glaciation (Warta stadial = Late Saalian). It was found that heavy-mineral assemblages in the Luciąża valley deposits are varied, particularly if compared with other fluvioglacial Quaternary deposits from the Polish lowlands, with a dominance of garnet. In the fluvial deposits of the Belnianka valley, zircon, staurolite and tourmaline dominate, with minor amounts of amphibole, pyroxene, biotite and garnet. This suggests that the deposits were subject to intensive and/or persistent chemical weathering and underwent several sedimentation/erosion cycles under periglacial conditions. In both valleys chemical weathering and aeolian processes were the main factors that modified the assemblages of the transparent heavy minerals; these processes were largely controlled by the climatic changes during the Pleistocene.
Climatic change on King George Island in the years 1948–2011

Published: June 2013

Abstract
The climatic change on King George Island (KGI) in the South Shetland Islands, Antarctica, in the years of 1948-2011 are presented. In the reference period, a statistically significant increase in the air temperature (0.19ºC/10 years, 1.2ºC in the analysed period) occurred along with a decrease in atmospheric pressure (−0.36 hPa/10 years, 2.3 hPa). In winter time, the warming up is more than twice as large as in summer. This leads to decrease in the amplitude of the annual cycle of air temperature. On KGI, there is also a warming trend of daily maximum and daily minimum air temperature. The evidently faster increase in daily minimum results in a decrease of the diurnal temperature range. The largest changes of air pressure took place in the summertime (−0.58 hPa/10 years) and winter (−0.34 hPa/10 years). The Semiannual Oscillation pattern of air pressure was disturbed. Climate changes on KGI are correlated with changing surface temperatures of the ocean and the concentra− tion of sea ice. The precipitation on KGI is characterised by substantial variability year to year. In the analysed period, no statistically significant trend in atmospheric precipitation can be observed. The climate change on KGI results in substantial and rapid changes in the environment, which poses a great threat to the local ecosystem.

Authors: Richter Dorota , Matuła Jan 
Published: June 2013

Abstract
This paper describes in detail the phenotypic traits of the newly discovered Leptolyngbya sieminskae sp. n. (Cyanobacteria). The species was found at two islands of the Svalbard archipelago (Spitsbergen and Nordaustlandet) in habitats which differed in humidity, water sources and altitude. The research was conducted at two fjords: on the southern side of Spitsbergen - Hornsund (77ºN, 015ºE) and the north−west side of Nord− austlandet - Murchisonfjord (80ºN, 018ºE). Although Leptolyngbya sieminskae was found in different latitudes no significant morphological differences were found between the specimens from both sites. The only visible difference is in the thickness of filaments and sheaths.
Basque Resultatives and Related Issues

Marc Bavant. Basque Resultatives and Related Issues. Lingua Posnaniensis, vol. LIV (2)/2012. The Poznań Society for the Advancement of the Arts and Sciences. PL ISSN 0079-4740, ISBN 978-83-7654-252-2, pp. 7-22.
Basque has an impressive number of resultative constructions for transitive verbs, not to mention dialectal variants. The purpose of this paper is to classify them according to Nedjalkov’s typology and compare Basque resultatives with similar periphrastic constructions in Classical Armenian. On the way, we meet the questions of Basque diatheses, of voice ambiguity of past participles, and of the affinity between possession and resultativity. The paper is based on material available in the literature and discussions with a native speaker or a specialist of the field. It appears that only “mediopassive”, a detransitivizing transformation, can be considered a diathesis, whereas the so-called “passive” and “antipassive” are respectively an objective and a subjective resultative. Also LAFITTE’S so-called “parfait” (1979) is a resultative, possessive in form and rather subjective in meaning. Classical Armenian displays a strikingly similar series of resultatives and the same kind of voice ambiguity for its past participle. It is hypothesized that the voice ambiguity may be related to the existence of a possessive resultative construction.
The Lithuanian Have-Resultative – A Typological Curiosum?

ABSTRACT
Björn Wiemer. The Lithuanian HAVE-resultative - A Typological Curiosum? Lingua Posnaniensis, vol. LIV (2)/2012. The Poznań Society for the Advancement of the Arts and Sciences. PL ISSN 0079-4740, ISBN 978-83-7654-252-2, pp. 69-81.
This article presents the Lithuanian possessive resultative construction with the verb turėti ‘have’ and discusses its place in a typology of forms of resultative constructions. While possessive resultatives with a past passive participle (as in Polish Kolację mamy już przygotowaną lit. ‘We have the dinner already prepared’) are found in areally related as well as other languages, Lithuanian stands out in using an active participle (more precisely: a participle always oriented toward the highest-ranking argument). The construction can be regarded as a rarum. However, it most probably did not develop in the way proposed by HARRIS (2010) as explanation for the emergence of rara. The rarity of the Lithuanian construction calls for an in-depth diachronic study, whose results may shed new light on the development of rare linguistic features.
Influence of Five Clonal Rootstocks on the Growth, Productivity and Fruit Quality of ‘Sylvia’ and ‘Karina’ Sweet Cherry Trees
Authors: Sitarek Mirosław , Bartosiewicz Barbara 
Published: June 2013

Abstract
In the field experiment, 8-year-old ‘Sylvia’ and ‘Karina’ sweet cherry trees grafted on ‘GiSelA 3’, ‘GiSelA 5’, ‘Piku 4’and ‘Weiroot 72’ clonal rootstocks were compared with trees of the same cultivars on the standard rootstock F 12/1. The data collected included tree vigour (expressed as trunk cross-sectional area − TCSA), yield, and fruit weight as well as content of soluble solids in fruit.
Based on TCSA, the largest ‘Sylvia’ and ‘Karina’ trees were on ‘F12/1’, and the smallest were on ‘GiSelA 3’. The results revealed that all of the tested rootstocks being compared to ‘F 12/1’, significantly reduced the growth of sweet cherry trees.
‘Sylvia’ trees on ‘GiSelA 5’ and ‘Piku 4’ yielded more than those on ‘F12/1’. The highest cumulative yields of ‘Karina’ were harvested from trees on ‘GiSelA 5’. ‘Karina’ trees on ‘GiSelA 3’, ‘Piku 4’ and ‘Weiroot 72’ performed comparably in cumulative yields to those on ‘F12/1’. Rootstock effects on yield efficiency were consistent between the two cultivars, with the most yield efficient trees on ‘GiSelA 3’, ‘GiSelA 5’ and ‘Weiroot 72’, and the least efficient trees on ‘F12/1’.
Trees of both cultivars grafted on ‘GiSelA 3’ produced significantly smaller fruits than those grafted on ‘F 12/1’. The rest of the rootstocks, tested in terms of an effect on fruit weight (with the exception of ‘Karina’ on ‘Weiroot 72’), had a similar value to ‘F 12/1’. Effects of rootstock on content of soluble solids in fruit were modest and statistically insignificant.

Authors: Czynczyk Alojzy , Bielicki Paweł 
Published: June 2013

Abstract
A field study of dwarf apple rootstock performance using ‘Golden Delicious Reinders’ as scion cultivar was conducted during the year 2001-2011. The study included 6 rootstocks from Cornell Geneva rootstock breeding program (G.11, G.16, G.41, G.202, CG.3007 and CG.4013) 4 rootstocks from the Polish rootstock breeding program (P 14, P 16, P 59 and P 60) and 3 Malling rootstocks as control (M.9 T337, M.9 Pajam 2 and M.26). During the eleven years of growth (2001-2011), there was no tree loss due to root system or cultivar damage caused by frost or diseases including fire blight (Ervinia amylovora Burr. Winsl.) infestation on the rootstock. Trees growing on P 59 and P 16 had the weakest growth while the strongest growing trees were on P 14, M.26, P 60, G.202 and CG.4013. The size of the trees on M.9 Pajam 2, G.16, G.41, CG3007 and CG.4013 were similar to that of the trees growing on the standard rootstock M.9 T337, while the trees on P 59, P 16 and G.11 were significantly smaller from standard trees on M.9 T337. After eleven years of the growth, the cumulative yield varied from 56.7 kg (on P 59) to 237.8 kg (on CG.4013). High yields were also obtained from vigorously growing trees on: G.202, P 14, G.41 and M.26. The cumulative yield expressed as yield per cm2 of trunk cross-sectional area was highest for trees on G.11, P 16, M.9 Pajam 2 and G.41 and lowest for vigorously growing trees on P 60, P 14 and M.26. In 2009, a year of good cropping, the mean mass of fruits varied from 140 g on G.16 to 213 g on P 60. The fruit size from trees on P 14, M.26 and P 16 was statistically similar to fruits from trees on M.9 T337. The results of the eleven-year study lead to the conclusion that the rootstocks G.11 and G.41, which are highly resistant to fire blight, can be recommended for growing ‘Golden Delicious Reinders’ apple in the Polish climate, similarly to trees on M.9 T337, P 16 and M.9 Pajam 2. For orchards located on light soils the following rootstocks are also promising: G.202, CG.3007, CG.4013 and P 14 and P 60 rootstocks of polish selection.
Effects of Nutrient Sources on the Early Growth of Pineapple Plantlets (Ananas comosus (L) Merr) in the Nursery
Authors: Olusegun Omotoso Solomon , Akinkunmi Akinrinde Ezekiel 
Published: June 2013

Abstract
Inadequate information on the nutrition of pineapple limits its commercial production in Nigeria. The effects of poultry manure and urea (each at 50 and 100 kg N ha-1), as well as their 1:1 (organo-mineral) combinations at 50, 100, 150 and 200 kg N ha-1, on the early (nursery) growth of pineapple plantlets. Organo-mineral fertilization at 100 kg N ha--1 resulted in the highest D-leaf length, number of leaves, root length and leaf area, while the highest biomass production (approx. 304 g, just within the 300-400 g desirable range for transplanting to the field) was achieved at 150 kg N ha-1.
Quality of Apple Maidens as Influenced by the Frequency of Application of Different Fertilizers in the Organic Nursery − Preliminary Results
Authors: Grzyb Zygmunt S. , Piotrowski Wojciech , Bielicki Paweł , Sas Paszt Lidia 
Published: June 2013

Abstract
A study was conducted in an organic nursery, in 2010 and 2011, on the growth of scab-resistant maiden apple trees of the cultivars Topaz and Ariwa grafted on M.26 rootstock. The young trees were grown at a spacing of 25 cm × 1.0 m on a podzolic soil. On the basis of the differences in the thickness and height of the maidens, and the number of lateral shoots and their length, as well as the number of branched trees, the effects of various fertilizers were studied depending on the number of treatments applied to the plants, which were treated either once or twice with such products as granulated manure, Micosat, Humus UP, Humus Active + Aktywit PM, BF Amin, BF Quality, Tytanit and Vinassa. The control plants were not fertilized at all, or fertilized with NPK. The fertilizers were applied the first time to the soil and plants in the nursery in mid-May and the second time in early June. The results showed that using them in a double treatment did not result in improved plant growth in every case. Two applications of humic preparations, the so-called vermiculites (Humus UP, Humus Active + Aktywit PM with the addition of beneficial bacteria), BF Quality, and to some extent also BF Amin gave better results in terms of the quality of maiden trees than a single application of these products, whereas in the case of preparations such as Tytanit and Vinassa, treating plants with them for the second time did not result in a significant increase in the intensity of plant growth in relation to the plants treated only once during the early period of growth
The Comparison of Sensory Quality and Processing Potential of ‘Topaz’ Apples Grown in Organic Orchards and Orchards Managed in Integrated Production System

Published: June 2013

Abstract
The aim of the study was to compare the sensory quality of scab resistant ‘Topaz’ apples grown in certified organic orchards (ECO) with those grown in orchards managed within integrated method (IP), and to determine their potential processing suitability. Fruits were harvested in five certificated IP and ECO orchards at the optimum ripeness stage and stored for two months in normal atmosphere at 1 ºC. Apple quality was assessed one day after cold storage and after 7 days of storage at the temperature 18 ºC to simulate shelf life. The results of taste and flavour sensory assessment did not explicitly demonstrate the effect of the orchard management system on the overall eating quality. Although the fruits from the organic orchards were perceived as less sweet and sourer, the management system did not influence the overall eating quality. There was no effect of the growing technology on quality traits connected with aroma and overall texture assessment. Regarding appearance evaluation, fruits from organic orchards were characterized by a higher variation in shape and size, and more frequently than in the case of IP apples had blemishes, scars and rust, which negatively affected their attractiveness. Analysis of the chemical composition of fruits indicates that apples from organic orchards are characterized on average by higher titratable acidity and higher soluble solids content than apples from IP orchards, which could favour their potential application as the additive regulating acidity and shaping the desirable sensory traits of processed organic products.
