ABSTRACTPurposeThis study examined the 1-yr test–retest reliability and criterion validity of sedentary time survey items in a subset of participants from a large, nationwide prospective cohort.MethodsParticipants included 423 women and 290 men age 31 to 72 yr in the Cancer Prevention Study-3. Reliability was assessed by computing Spearman correlation coefficients between responses from prestudy and poststudy surveys. Validity was assessed by comparing survey-estimated sedentary time with a latent variable representing true sedentary time estimated from the 7-d diaries, accelerometry, and surveys through the method of triads. Sensitivity analyses were restricted to 566 participants with an average of 14+ h of diary and accelerometer data per day for 7 d per quarter.ResultsReliability estimates for total sitting time were moderate or strong across all demographic strata (Spearman ρ ≥ 0.6), with significant differences by race (P= 0.01). Reliability estimates were strongest for the TV-related sedentary time item (Spearman ρ, 0.74; 95% confidence interval, 0.70–0.77). The overall validity coefficient (VC) for survey-assessed total sedentary time was 0.62 (95% confidence interval, 0.55–0.69), although VC varied by age group and activity level (P< 0.05). However, VC were similar across groups (P< 0.05) when restricting to highly compliant participants in a sensitivity analysis.ConclusionsThe Cancer Prevention Study-3 sedentary behavior questionnaire has acceptable reliability and validity for ranking or categorizing participants according to sedentary time. Acceptable reliability and validity estimates persist across various demographic subgroups.
Perceptions of ePortfolio adoption in a non-medical prescribing programme
Authors: Bell Suzanne 
Published: August 2018

This article focuses on initial findings from a small study considering students' and staff's perceptions of the future adoption of an ePortfolio summative assessment. Aim: The study aimed to determine non-medical prescribing (NMP) students' and staff's perceptions of the potential future adoption of ePortfolio as a technological enhancement of the summative assessment. Background: The integration of ePortfolios in post-graduate nurse education is supported using current learning technologies within Higher Education Institutions and professional nursing bodies, yet little research has specifically focused on this group in the UK. Methods: This study employed a qualitative research approach with the methodology chosen to reflect pragmatic time-frames and access to the audience needed (NMP students and academic staff). The different qualitative approaches also afforded maximum opportunities for response, with no financial implication or ethical challenges. These approaches comprised a student focus group (seven NMP students), an online questionnaire (an additional seven NMP students) and an online questionnaire (five lecturers within the NMP module team). Results: Findings suggest there remains misapprehension around the terminology used to define ePortfolio, which may lead to heightened anxiety within the post-qualifying NMP student population. Overall, students and staff had positive perceptions of the future adoption of ePortfolio as an enhancement of the existing portfolio summative NMP assessment. Several themes emerged relating to the perceptions of staff and students including changing validation requirements of nursing governing body requirements, recognition of developing technologies in education and flexibility of online tools. Conclusion: There is scope to explore technological advances, including ePortfolio, within nurse prescribing education that may increase engagement of students and module staff to enhance development as well as allow innovative co-production.

AbstractThis paper presents analysis of profitability indicators of Polish construction companies threatened with bankruptcy compared to analogous indicators obtained by Polish construction entities as a whole.The analysis concerns companies generating positive and negative financial results (both EBIT and net financial results). Moreover, the operating profitability ratio, return on sales, and return on total assets ratios have been verified.The analyses have been conducted using financial reports of Polish construction companies which went bankrupt in 2013, as well as financial data of construction sector participants as a whole.
Depositional architecture of marginal multiple-source ramp of the Magura Basin (Eocene Flysch formation, Outer Western Carpathians)
Authors: Wójcik Ewa , Zielińska Magdalena , Chybiorz Ryszard , Żaba Jerzy 
Published: August 2018

Abstract
The Zembrzyce Beds were studied to interpret the environments and facies in the western part of the Siary Subunit. New sedimentological data were obtained for the reconstruction of the depositional architecture of the Zembrzyce Beds. Based on detailed facies analysis, 9 facies and 4 facies associations were recognized. The facies associations represent different architectural elements of a submarine fan, such as: termination of distributary channel with transition to depositional lobe (distal part of mid-fan/outer fan sub-deposystem), lobes and distal lobes (outer fan sub-deposystem). According to the classification of Reading & Richards (1994) the fan deposystem can be classified as mud/sand-rich ramp. This system consists of several elongated lobes that formed synchronously, migrated laterally, and then retreated or decayed. The depositional system was supplied from the north and north-east. The inner-fan sub-deposystem was not detected. The sediments were deposited by high- and low-density turbidity currents and hyper-concentrated density flows sensu Mulder & Alexander (2001) with participation of the depositional background processes (pelagic settling). The sedimentary conditions of the Zembrzyce Beds during the Late Eocene were controlled by tectonic movements, the progress of the subduction and the global sea level changes.
Nucleation and amplification of doubly-plunging anticlines: the Butkov pericline case study (Manín Unit, Western Carpathians)
Authors: Plašienka Dušan , Šimonová Viera , Bučová Jana 
Published: August 2018

Abstract
The Manín Unit represents a transitional tectonic element between the Central Western Carpathians and the Pieniny Klippen Belt. The overall map-view structure of the Manín Unit is dominated by elliptical antiforms composed of comparatively competent Jurassic and Lower Cretaceous strata, surrounded by soft Upper Cretaceous shales, marls and sandstones. During layer-parallel shortening, the Manín sedimentary succession behaved as a multilayer reinforced by a variously thick rigid layer of massive Urgonian limestone. The multilayer deformed by flexural slip folding, but the fold wavelength was controlled by the rigid layer undergoing buckling. It is inferred that, besides the lateral thickness differences in the rigid layer, development of brachyfolds and particularly periclines such as the Butkov fold also resulted from the interference of two perpendicular macroscopic fold systems.

Published: August 2018

Abstract
The Komjatice depression, situated on the Danube Basin’s northern margin, represents a sub-basin of the Neogene epicontinental Central Paratethys Sea and Lake Pannon. The paper provides an insight into the character of sediment provenance evolution by study of well cores (ZM-1, IV-1, MOJ-1, VR-1 wells). A modern combination of provenance, sedimentology and biostratigraphy together with the reported redefinition of Pannonian formations resulted in a new lithostratigraphy of the study area. Moreover, newly published volcanic rock age data were used for calibration of biostratigraphy. The overall age span of the sedimentary fill is occupied only by late Badenian–Sarmatian (Serravallian) to Pannonian (Tortonian–Messinian) strata: 1) the basal alluvial sediments of the newly defined Zlaté Moravce Formation; 2) late Badenian–Sarmatian (Serravalian) marine sediments of the Vráble-Pozba Fm., connected with tectonic opening of the depression; 3) Pannonian (Tortonian) coarse grained sediments of the Nemčiňany Fm. with an erosional base; 4) Pannonian (Tortonian–Messinian) predominantly fine-grained, basin floor to slope Ivanka Fm., sandy deltaic Beladice Fm. and predominantly muddy, alluvial Volkovce Fm. In the middle Miocene provenance is situated in Paleozoic sequences and Neogene volcanic rocks occurring currently in the NE. During the late Miocene, provenance is changed to the NNW (Tribeč Mts.), although the transport from the NE also remained.

Abstract
This paper studies the effect of globalization on small and medium enterprises (SMEs) performance in Nigeria. The study adopts an ex post-facto type of descriptive research design. In carrying out this study, the secondary statistics data was used. Data was extracted from CBN bulletin on relevant information which depicts globalization and its effect on SMEs performance in Nigeria.A co-integration model was used to investigate the effect of globalization on SMEs performance in Nigeria. To capture the activities of globalization, three proxies were used to capture the activities of globalization; they include interest rate, bank credit and trade openness while on the other hand, output of SMEs to GDP was used to capture SMEs performance covering the period of 1992 to 2014. It was observed that interest rate, bank credit and trade openness do not improve the performance of SMEs output. The overall effect as shown by the F-statistics reveals that the variables considered in this study are not significant in explaining the level of improvement in SMEs output and performance in Nigeria.

Abstract
Personal bankruptcies are traditionally discussed from legal, microeconomic or social point of view. This paper focuses on the development of personal bankruptcies in the Czech Republic during the time period 2008-2016 and aims to connect performance of economy and the development of personal bankruptcies. As statistical tools there are used descriptive statistics and regression and correlation analysis. For the economy performance are used the measures of GDP, unemployment rate, household indebtedness and share of debts in default. Based on the results of the analysis there shall be said that lower economic performance influences increasing number of personal bankruptcies. This conclusion has significant consequences for the government and its politics, banks and other financial institutions.

Abstract
The aim of this paper was to examine university students’ propensity for entrepreneurship in the context of the evaluation of the quality of macro-environment and business environment. A part of this aim was a comparison of defined factors in the Czech and the Slovak Republic. In relation with the research aim, a survey-based research was conducted with university students in the Czech Republic and Slovakia. 409 students in the Czech Republic and 568 students in Slovakia were approached during this research. To verify the defined scientific hypotheses, the regression analysis was used. The research results brought interesting findings, namely that the present macroeconomic environment does not prevent students from starting their own business, and that the present level of basic macroeconomic factors (GDP, employment, inflation) determine the students’ propensity for entrepreneurship in both countries. In Slovak Republic, the administrative workload is seen by the students as a factor discouraging them from entrepreneurship after graduating from college. The students feel that the conditions for doing business have improved in the last five years. Students in the Czech Republic think that the conditions for doing business have improved over the past five years, and consider the business environment to be reasonably risky and of good quality.
Influencing the anticorrosion efficiency of pigments based on zinc ferrite by conductive polymers
Authors: Nechvílová K. , Kalendová A. 
Published: August 2018

Abstract
Generally, organic coatings which contain zinc ferrites are able to protect metal substrate, most often low-carbon steel, by inhibition mechanism. Conductive polymers are using a system of conjugated double-bonds to transfer a charge over the chain thereby providing their own electrical conductivity in the organic coatings. The charge from the chain in combination with the iron substrate generates electrons to the formation of passivation products on the surface of paint film. This paper is focused on combination of zinc ferrite with conductive polymer and using of synergic effect of these two components. The organic coatings were formulated from hematite and specularite on pigments concentration line 5, 10, 20 and 25 wt.% for better recognizing of the effectiveness of zinc ferrite component. The content of the conductive polymer was consistently set at 3 wt.% in each organic coating. A solvent-based epoxy-ester resin was used as a binder. The physico-mechanical and corrosion tests were performed for all samples. The corrosion signs were evaluated on the surface of coating and also on the surface of metal substrate. In the end, the efficiency was compared alone zinc ferrite and alone polymers and also their combinations.
Habitat characteristics of the Japanese water shrew, Chimarrogale platycephalus
Authors: Iwasa Masahiro A. 
Published: August 2018

Abstract
To determine the habitat characteristics of the Japanese water shrew, Chimarrogale platycephalus, seven stream parameters were studied along five streams. The shrew occurred along three of those streams. To evaluate the stream parameters related to water shrew occurrence as an objective variable, a generalized linear model analysis of the five streams was performed. The results indicated that current velocity was the most important parameter in shrew occurrence at p<0.001. The present findings are similar to those for the European water shrew, Neomys fodiens. The number of invertebrates as availability of food resources, however, was not a significant parameter influencing shrew occurrence. Along the banks of the two streams inhabited by C. platycephalus, there are artificially managed leisure fishing sites, and small fish farms have released fish regularly into the streams to stock up fishing resources. Such management of leisure fishing may provide the water shrews with fish as an additional food resource and possibly contribute to the occurrence of C. platycephalus.
Structure mediation and ductility enhancement of poly(l-lactide) by random copolymer poly(d-lactide-co-ε-caprolactone)

Published: August 2018

Abstract
Two types of random copolymer poly(d-lactide-co-ε-caprolactone) (PDLA-r-PCL) were added into poly(l-lactide) (PLLA) matrix by melt blending. The structure and property of PLLA/PDLA-r-PCL blends were investigated by thermal gravimetric analysis, differential scanning calorimetry, scanning electron microscopy, wide-angle X-ray diffraction, and mechanical measurement. The results suggested that PDLA-r-PCL had little effect on the thermal property of PLLA. PDLA-r-PCL uniformly dispersed in PLLA matrix, which contributed to the improvement of stretching properties. During stretching at 25°C, with the increased content of PDLA-r-PCL, the elongation at break of PLLA increased and the strength decreased. The degree of decrease in fracture strength was related to the molecular structure of PDLA-r-PCL. When a small amount of stereocomplex crystals (SC) were formed in PLLA/PDLA-r-PCL blends, the strength was maintained or slightly enhanced even though the elongation at break of the blends was significantly improved by soft chains of PCL. It might be caused by the synergistic effects of SC crystals and plasticization of PCL chains.
Enumeration of small Wilf classes avoiding 1342 and two other 4-letter patterns
Authors: Callan David , Mansour Toufik 
Published: August 2018

Abstract
This paper is one of a series whose goal is to enumerate the avoiders, in the sense of classical pattern avoidance, for each triple of 4-letter patterns. There are 317 symmetry classes of triples of 4-letter patterns, avoiders of 267 of which have already been enumerated. Here we enumerate avoiders for all small Wilf classes that have a representative triple containing the pattern 1342, giving 40 new enumerations and leaving only 13 classes still to be enumerated. In all but one case, we obtain an explicit algebraic generating function that is rational or of degree 2. The remaining one is shown to be algebraic of degree 3. We use standard methods, usually involving detailed consideration of the left to right maxima, and sometimes the initial letters, to obtain an algebraic or functional equation for the generating function.

Teilhabe für arbeitsmarktferne Arbeitslose durch einen Sozialen Arbeitsmarkt – Chancen und Risiken eines notwendigen Instruments
Authors: Kupka Peter , Möller Joachim , Lobato Philipp Ramos , Wolff Joachim 
Published: August 2018

AbstractWe discuss a new scheme of subsidized jobs for unemployed people with extremely low job finding prospects. This scheme, referred to as Social Labour Market, primarily intends to promote their social inclusion. Research on public employment schemes has shown that it is of utmost importance to define very narrow criteria for participation in order to avoid lock-in-effects. Due to health issues and other severe employment impediments of the participants, the design of a social labour market should allow for flexible work arrangements and include some kind of mentoring (“job coaches”). We conclude that the scheme planned by the German government basically meets many criteria recommended by labour market researchers but still bears some risk of “creaming”. We recommend to start with a small number of participants. This should help to test the process of assigning participants and assess the effectiveness of different designs of the scheme before boosting the number of participants to the ultimate size.

[article in English; abstract and key words in English and Lithuanian]
This paper analyzes the economic activities of the Conventual Franciscans in the early modern urban society of Vilnius from the second part of the 17th until the end of the 18th centuries. We ask the key question whether the Franciscans had embraced the “profit economy” in a similar way that Lester K. Little famously portrayed them do in the Latin Christendom at the end of the medieval ages. This paper will look at the economic model of the Franciscan order based on their income and expenses books, and it will delve into their key economic activities: financial services and property management.

Published: August 2018

The eco-tourism area of the southern coast of West Java is the focus of research since the area is less well known as a tourist destination. Also, there is a reluctance of tourists to visit again, and tourists find ordinary. The purpose of this study is to examine the influence model of travel motivation and impressive tourism experience towards the destination image. The method used is verification analysis by using Structural Equation Model (SEM). The survey conducted on 302 respondents, i.e., tourists who visited the eco-tourism area of the southern coast of West Java. The results showed the motivation of travel and tourism experience significantly influence the image of tourism destinations. Tourism area managers need to design strategies to improve the image of the region by providing tourist stimulation in the form of exciting information and offers eco-tourism products-themed for tourist with a memorable approach to traveling experiences.DOI: 10.15408/etk.v17i2.7211
