Polski Współczynnik Wpływu a kultury cytowań w humanistyce
Authors: Drabek Aneta , Rozkosz Ewa A. , Hołowiecki Marek , Kulczycki Emanuel 
Published: June 2016

W artykule omawiamy wzór na nowy polski wskaźnik bibliometryczny, tj. Polski Współczynnik Wpływu, z perspektywy nauk humanistycznych. Badaniom poddaliśmy dwa prestiżowe polskie czasopisma humanistyczne („Pamiętnik Literacki” i „Diametros – An Online Journal of Philosophy”), aby sprawdzić poprawność założeń przyjętych dla Polskiego Współczynnika Wpływu. Przeanalizowaliśmy wszystkie artykuły opublikowane w latach 2004–2014 (odpowiednio: N = 850, N = 555) i wszystkie prace w nich zacytowane (odpowiednio: N = 21 805, N = 8 298). W interpretacji wyników przyjęliśmy założenie o odmiennej kulturze cytowań w różnych grupach nauk. Wyniki pokazują, że wzór na Polski Współczynnik Wpływu nie bierze pod uwagę najczęściej cytowanych źródeł w humanistyce, tj. książek i rozdziałów. Poza tym wiele cytowań nie zostanie uwzględnionych przy wyliczaniu Polskiego Współczynnika Wpływu ze względu na ich wiek, ponieważ będą brane pod uwagę prace co najwyżej pięcioletnie lub nowsze. Zbadaliśmy wiek cytowanych tekstów i pokazaliśmy, że większość z cytowań jest starsza niż 5 lat (odpowiednio: 84,2% oraz 73,2%). Nasza analiza pokazuje, że Polski Współczynnik Wpływu nie jest odpowiednim narzędziem do bibliometrycznej oceny czasopism humanistycznych w Polsce. Artykuł kończy dyskusja nad możliwościami ulepszenia tego nowego wskaźnika bibliometrycznego.
Determining Values Using Options Contracts
Authors: Seiglie Carlos , Xiang Jun 
Published: June 2016

Abstract
This paper presents a simple mechanism for allocating a single good in partnership dissolution. Since in the areas of probate, family, partnership and bankruptcy law the establishment of the value of assets is essential this mechanism can be useful. We illustrate its application for the case of determining the value of a house in a divorce proceeding. We show that when transactions costs are permitted, our mechanism shows a wider range of equilibrium outcomes than existing mechanisms such as Texas shootouts, implying it offers more equal and fair divisions. In addition, if private valuations of an asset are allowed, the proposed mechanism has an advantage based on the efficiency criterion compared to Texas shootouts.

Equisetum ×moorei Newman (Equisetaceae) – a ‘new’ nothotaxon in the Polish flora
Authors: Kalinowski Paweł , Sliwinska Elwira , Kruk Jerzy 
Published: June 2016

Abstract
To investigate present and historical distribution of Equisetum ×moorei in Poland and its habitat requirements, field studies at sites of potential occurrence of this hybrid taxon as well as literature and herbarium search were performed. As a results of these investigations, E. ×moorei was found at five contemporary and at a few historical localities in the present territory of Poland. Since the Equisetum populations near Olkusz (S Poland) showed phenotype similar, to some extent, to triploid hybrid E. ×ascendens, we performed nuclear DNA content analysis of these populations. However, it turned out that the investigated individuals belonged to a diploid taxon that can be ascribed to E. ×moorei.
Elevated bark temperature in unremoved stumps after disturbances facilitates multi-voltinism in Ips typographus population in a mountainous forest

Published: June 2016

Abstract
The number of Ips typographus generations developed in a year might be indicative of its population size and of risk to Norway spruce forests. Warm weather and unremoved fallen trees after natural disturbances are thought of as key factors initiating large population increase. We studied I. typographus development in a spruce forest of the Tatra National Park, which was heavily affected by large-scale disturbances in the last decade. Repeated windthrows and consequent bark beetle outbreaks have damaged almost 20,000 hectares of mature Norway spruce forests, what is a half of the National Park forest area. Current I. typographus population size and its response to the environment and to forestry defense measures attract attention of all stakeholders involved in natural resource management, including public. In this paper we analyse the potential I. typographus population size in two consecutive years 2014 and 2015, which represented a climatologically normal year and an extremely hot year, respectively. We used bark temperature and phenology models to estimate the number of generations developed in each year. In 2014, the average bark temperature of standing living trees at study sites was 14.5 °C, in 2015 it increased to 15.7 °C. The bark temperature of fallen logs was 17.7 °C in 2014, and 19.5 °C in 2015. The bark temperature of standing living trees allowed to develop one and two generations in 2014 and 2015, respectively. The elevated bark temperature of fallen logs allowed to develop two generations in 2014 and three generations in 2015. The good match between the predicted and observed timing of each generation emergence as well as the large increase in the number of catches in pheromone traps in 2015 indicated a dramatic increase of the I. typographus population in the extremely warm year, especially at the unmanaged windthrown site.
Approaches to the talent management agenda in forestry companies
Authors: Vnoučková Lucie , Urbancová Hana , Smolová Helena 
Published: June 2016

Abstract
Professional literature and practice started to focus intensively on the field of talent management. A lack of talented individuals occurred in all sectors worldwide. The war for talents has not faded out, on the contrary, it has been intensifying. The aim of the paper is therefore to analyse the perception of opportunities for development and management of talents in forestry and to specify characteristics of employee/ talent support perception in surveyed companies. The analysis is based on a primary survey conducted in 101 forestry companies. The data were obtained through surveys in which one manager and one employee represented a single company. One-dimensional and multidimensional statistics were used to evaluate the data. The results showed that employees perceived developmental conditions in companies more positively than what was stated by managers and company representatives. The average difference in the perception was 8.5%; employees perceived the conditions better than company representatives. When negative phenomena were analysed, the perception was quite opposite. The average difference was 9.5%. The limit of the paper is the narrow focus on primary sector companies. The results may help surveyed companies in the primary sector to encourage managers and employees to participate in developmental programmes as their own initiative and willingness to take part in education and developmental activities was found.
Carex divisa in Slovakia: overlooked or rare sedge species?
Authors: Dítě Daniel , Eliáš Pavol , Melečková Zuzana 
Published: June 2016

Abstract
Historical and current occurrence of halophytic species Carex divisa was studied in Slovakia during 2003–2014. It is known only in the Podunajská nížina Lowland, SW Slovakia, where 19 sites were found in total including historical and recent locations. Recently, the number of records decreased markedly and we confirmed only 9 localities. Due to the sharp reduction in the number of sites and appropriate habitats, Carex divisa is re-evaluated as endangered (EN) plant species of the Slovak flora.

Authors: Rodríguez-Flores Shantal , Escuredo Olga , Seijo Maria Carmen 
Published: June 2016

Abstract
In recent years, authentic foodstuffs have became a major requirement for consumers and producers worldwide. Honey has increased in popularity since it is associated with a natural diet, and because of honey’s authentic origin. The present study investigated the palynological characteristics, physicochemical parameters, total phenol content, flavonoid content, and radical scavenging activity of 41 sweet chestnut (Castanea sativa) honeys from the northwestern part of Spain. These honeys were characterised by high values of electrical conductivity, pH, diastase content, and colour. All the samples showed a pollen combination of Castanea sativa-Rubus-Cytisus type-Erica. Fructose and glucose were 37.2% and 25.9%, while other sugars were less than 5%. Regarding the mineral content K, was the main with a mean value of 260.2 mg/100g. Other elements as Mg with a mean value of 17.1 mg/100g, Ca (mean value of 15.8 mg/100g) and P (mean value of 12.8 mg/100g) were well represented in this honey type. The phenol and flavonoid content were high (mean values of 129.8 mg/100g and 9.0 mg/100g, respectively). Multivariate statistical techniques showed the close relationship of colour, Mg, P, phenols, melezitose, and flavonoids, and the radical scavenging activity.
Reproductive potential and nesting effects of Osmia rufa (syn. bicornis) female (Hymenoptera: Megachilidae)

Published: June 2016

Abstract
The red mason bee Osmia rufa is a solitary bee belonging to the family Megachilidae, and is prone to nest in aggregations. Each female builds a nest separately in pre-existing cavities such as holes in wood and walls or empty plant stems. This is done by successively setting the cells in a linear series. In this study, we elucidate the nesting behavior and the reproductive potential of a single O. rufa female. The reproductive potential of nesting females was evaluated after the offspring finished development. We observed that an individual female may colonize up to five nest tubes and build 5-34 cells in them (16 on an average). During the nesting time the number of cells decreased with the sequence of nest tubes colonized by one female, which built a maximum of 11 cells in the first occupied nest and 5 cells in the last (fifth nest). Our observations indicated that 40% of nesting females colonized one nest tube as compared to 7% colonizing five nest tubes. Furthermore, in subsequent nest tubes the number of cells with freshly emerged females gradually decreased which was the reverse with males. Thus, the sex ratio (proportion of male and female offspring) may change during the nesting period. The female offspring predominated in the first two nesting tubes, while in the subsequent three tubes male offspring dominated. We also cataloged different causes of reduction in abundance of offspring in O. rufa females such as parasitization or problem associated with moulting.
Efficiency of GC-MS method in detection of beeswax adulterated with paraffin

Published: June 2016

Abstract
The efficiency of the gas chromatography - mass detector (GC-MS) technique for the detection of beeswax adulterated with paraffin, was evaluated. For this purpose, beeswax samples with paraffin additions (3, 5, 10, 30, 50%) were analysed. Since not enough is known about paraffin compositions, and since it is difficult to detect paraffin in beeswax, the aim of our research was also to compare the hydrocarbon composition of different types of paraffin. The analysis showed that the types of paraffin available on the market, differ qualitatively and quantitatively as far as their hydrocarbon compositions are concerned. In all kinds of paraffin, we found homologous series of n-alkanes that were much longer than those in beeswax. In beeswax, the amount of added paraffin that is possible to detect, differs and depends on the kind of paraffin used for adulteration. In this study, the minimum estimated percent that was detected using the GC-MS technique, was 3%. The adulteration is indicated by the presence of hydrocarbons containing over 35 carbon atoms in the molecule, and by the higher contents of n-alkanes (C20H42 - C35H72), in comparison to the concentration of these compounds determined in pure beeswax. We also presented the results of the quality control of commercial beeswax. Based on our results, it can be stated that beeswax adulteration is currently a problem.

Abstract
Honeybee collected pollen exhibits high nutritional and pharmaceutical benefits for the human diet and medicine. Pollen’s antioxidant, anti-ageing, anti-inflammatory, anti-atherosclerosis, and cardioprotective activity, depending on the floral origin, are well known. Recent studies proposed that pollen may also be an excellent cancer-fighting candidate, as pollen harbours high amounts of phenolic substances. In our study, Filipendula ulmaria pollen (bee collected) was methanol-water extracted and used to verify its in vitro pharmacological activities on C26 mice cancer tumour cells. Three different concentrations of the extract were tested in antitumour assays. Monitoring was done after 6, 12, 24, and 48 hours. Promising results were obtained for antiproliferative and apoptotic activity of the pollen extracts, with high efficiency for the highest concentration (1 mg/mL). For both activities, time and concentration-dependent effects were observed. Pollen extracts or bee collected pollen has a high potential as an antitumour agent for use in human medicine, because they are both rich in bioactive compounds.

Published: June 2016

Abstract
Introduction: In-stent restenosis (ISR) is traditionally associated with neointimal hyperplasia. However, recent studies have suggested that an underlying progression of the atherosclerotic process called neoatherosclerosis, different from intimal proliferation, could be involved in ISR development. In this study the aim was to compare the characteristics of the neoatheromatous plaque evidenced by Multislice Angio Computed Tomography, Optical Coherence Tomography (OCT) and Virtual Histology Intravascular Ultrasound (VH-IVUS) with the characteristics of de-novo lesions in native coronary vessels of patients with ISR. Material and methods: This is a prospective single-center pilot study in which patients presenting with acute chest pain and having at least one symptomatic bare-metal stent (BMS) restenosis at six months to one year after BMS implantation, were enrolled. The characteristics of the neointimal tissue developed within the implanted stents using Acio CT, OCT and VH-IVUS were studied. Results: In total, 27 patients with 38 coronary BMS were included in the study, in whom 27 ISR lesions and 43 lesions in native coronary vessels were identified. Angio CT examination revealed that atheromatous plaques responsible for ISR tend to have a larger volume compared with native lesions located in the same coronary vessel (plaque volume 91.2 mm3 for ISR vs. 60.4 mm3 for native vessels, p <0.0001). Additionally, they show more low density plaques compared to native coronary lesions located in the same coronary vessel (33.9 mm3 vs. 18.2 mm3 for the volume of the plaque with density <30 HU, p <0.0001). Plaques responsible for ISR exhibit a higher lipid content than native ones (41.1% vs. 22.9%, p = 0.05). OCT analysis indicated an irregular shaped vascular lumen in 44.4% of ISR lesions compared to 25.6% of de-novo lesions (p = 0.1). Conclusions: Neoatherosclerosis within the implanted coronary stents is associated with signs of plaque vulnerability to a significantly higher extent than the atheromatous plaques in native coronary arteries in patients with ISR presenting with an acute coronary syndrome.
Something Old, Something New, Something Borrowed, Something Blue: Part 3 – An Elephant Never Forgets
Authors: Dougherty Mark 
Published: June 2016

AbstractForgetting is an oft-forgotten art. Many artificial intelligence (AI) systems deliver good performance when first implemented; however, as the contextual environment changes, they become out of date and their performance degrades. Learning new knowledge is part of the solution, but forgetting outdated facts and information is a vital part of the process of renewal. However, forgetting proves to be a surprisingly difficult concept to either understand or implement. Much of AI is based on analogies with natural systems, and although all of us have plenty of experiences with having forgotten something, as yet we have only an incomplete picture of how this process occurs in the brain. A recent judgment by the European Court concerns the “right to be forgotten” by web index services such as Google. This has made debate and research into the concept of forgetting very urgent. Given the rapid growth in requests for pages to be forgotten, it is clear that the process will have to be automated and that intelligent systems of forgetting are required in order to meet this challenge.

Published: June 2016

AbstractObjective:The present study aims to compare the presence and localization of collagen type IV in the prenasal tissue of fetuses with and without Down syndrome (DS).Methods:Products of conception were obtained from mid-gestation uterine evacuations of 14 DS fetuses and 15 unaffected controls. Microdissection of the prenasal area and an analysis of the prenasal tissue specimens were performed by a single pathologist, blinded to the karyotype results. Immunohistological presence and localization of type IV collagen were analyzed in the basement membrane (BM), blood vessels, and stroma of the tissues.Results:There were no statistically significant differences in the presence and localization of antibodies for collagen IV in the blood vessels and stroma between the two groups. However, the presence and localization of type IV collagen in the BM of the prenasal skin were significantly higher in DS specimens compared to the control group (P=0.023). When combining both groups altogether, a significant correlation was found between the increased prenasal thickness (PT) and the high presence and location of collagen type IV, irrespective of the karyotype results (Spearman’s correlation; R=0.459; P=0.012).Conclusion:Using the immunohistochemistry technique, we were able to confirm the overexpression of collagen type IV in the BM of the prenasal area. This may explain the sonographic finding of increased PT seen mainly in DS fetuses.
Surrogate markers of insulin resistance in subjects with metabolic syndrome – data of the Berlin Aging Study II
Authors: Buchmann Nikolaus , Norman Kristina , Demuth Ilja , Steinhagen-Thiessen Elisabeth 
Published: June 2016

Abstract

Background: The metabolic syndrome (MetS) is a cluster of metabolic changes which is associated with insulin resistance (IR). Cutoff values for the homeostasis model of insulin resistance (HOMA-IR) – a surrogate marker of IR-to identify subjects with MetS are not established.

Methods: Cross-sectional data of 446 younger (53% women, 28±3 years old) and 1271 elderly study participants (52% women, 68±4 years old) without diabetes were available for the current analysis. MetS was defined according to the IDF/AHA/NHLBI (International Diabetes Federation/American Heart Association/National Heart, Lung, and Blood Institute) criteria of 2009. Using receiving operating characteristics (ROC) analysis cutoff values for HOMA-IR were calculated above which participants with MetS could be identified with highest sensitivity and specificity. Finally, binary logistic regression models were calculated.

Results: The prevalence of MetS was 6.7% in young and 28.3% in elderly subjects. HOMA-IR cutoff values for the detection of MetS were HOMA-IR >1.88 (young subjects; sensitivity 80%, specificity 85.3%, positive predictive value 80%, negative predictive value 15%) and HOMAIR >1.98 (elderly subjects; sensitivity 73.6%, specificity 72.9%, positive predictive value 74%, negative predictive value 27%). In adjusted regression models [age, body mass index (BMI), sex, physical activity and age groups] subjects above these cutoff-values had odds of 5.7 [95% confidence interval (CI): 4.1–7.9] in elderly and 22.2 (95% CI: 7.0–70.5) in younger study participants to have MetS.

Conclusions: Cutoff values for HOMA-IR are not established in clinical practice; however, they could be used to identify subjects with MetS, even if a diagnosis of MetS cannot made based solely on HOMA-IR considering the negative predictive values.
