ObjectivesImplant-related infection is one of the most devastating complications in orthopaedic surgery. Many surface and/or material modifications have been developed in order to minimise this problem; however, most of the in vitro studies did not evaluate bacterial adhesion in the presence of eukaryotic cells, as stated by the ‘race for the surface’ theory. Moreover, the adherence of numerous clinical strains with different initial concentrations has not been studied.MethodsWe describe a method for the study of bacterial adherence in the presence of preosteoblastic cells. For this purpose we mixed different concentrations of bacterial cells from collection and clinical strains of staphylococci isolated from implant-related infections with preosteoblastic cells, and analysed the minimal concentration of bacteria able to colonise the surface of the material with image analysis.ResultsOur results show that clinical strains adhere to the material surface at lower concentrations than collection strains. A destructive effect of bacteria on preosteoblastic cells was also detected, especially with higher concentrations of bacteria.ConclusionsThe method described herein can be used to evaluate the effect of surface modifications on bacterial adherence more accurately than conventional monoculture studies. Clinical strains behave differently than collection strains with respect to bacterial adherence. Cite this article: M. Martinez-Perez, C. Perez-Jorge, D. Lozano, S. Portal-Nuñez, R. Perez-Tanoira, A.

Somaclonal Variation During Picea abies and P. omorika Somatic Embryogenesis and Cryopreservation
Authors: Hazubska-Przybył Teresa , Dering Monika 
Published: May 2017

AbstractEmbryogenic cultures of plants are exposed to various stress factors bothin vitroand during cryostorage. In order to safely include the plant material obtained by somatic embryogenesis in combination with cryopreservation for breeding programs, it is necessary to monitor its genetic stability. The aim of the present study was the assessment of somaclonal variation in plant material obtained from embryogenic cultures ofPicea abies(L.) Karst. andP. omorika(Pančić) Purk. maintainedin vitroor stored in liquid nitrogen by the pregrowth-dehydration method. The analysis of genetic conformity with using microsatellite markers was performed on cotyledonary somatic embryos (CSE), germinating somatic embryos (GSE) and somatic seedlings (SS), obtained from tissues maintainedin vitroor from recovered embryogenic tissues (ETc) and CSE obtained after cryopreservation. The analysis revealed changes in the DNA of somatic embryogenesis-derived plant material of bothPiceaspp. They were found in plant material from 8 out of 10 tested embryogenic lines ofP. abiesand in 10 out of 19 embryogenic lines ofP. omorikaafterin vitroculture. Changes were also detected in plant material obtained after cryopreservation. Somaclonal variation was observed in ETc and CSE ofP. omorikaand at ETv stage ofP. abies. However, most of the changes were induced at the stage of somatic embryogenesis initiation. These results confirm the need for monitoring the genetic stability of plants obtained by somatic embryogenesis and after cryopreservation for both spruce species.

Maraena whitefish (Coregonus maraena) larvae reveal enhanced growth during first feeding with live Artemia nauplii
Authors: Bochert Ralf , Horn Theresa , Luft Peter 
Published: May 2017

Abstract
Newly hatched Coregonus maraena (Bloch) larvae reared in aquaria were observed during two trials in 2014 and 2015 for 42 and 34 days after hatching in order to determine the on-feeding effects of different feeding strategies on growth and survival. Feeds of commercial dry feed, live Artemia nauplii, frozen rotifers, and mixtures of these were compared. Larval whitefish were fed brine shrimp for up to 13 days beginning 4 days post hatch (dph). Whitefish larvae fed live Artemia for 8-9 h per day over a period of 10-12 days grew considerably larger (mean value of final total length (TL) 27.3-33.0 mm)) and were heavier (mean value of final body weight (BW) 112-165 mg)) than those fed dry feed, frozen rotifers, or Artemia for 3-6 days (TL= 22.6-30.2 mm; BW= 50-102 mg). The growth of larvae fed for 24 h solely on dry food was comparable (BW= 101 mg, TL= 26.6 mm) at 42 dph. Survival differed among groups (31-63%) and was highest for larvae fed dry food exclusively. Our results can improve the first feeding of Maraena whitefish larvae in small-scale fish farms.
An attempt to assess the ecological status of a lake based on historical and current maps of submerged vegetation

Published: May 2017

AbstractThe possibility of doing a back assessment of the ecological status of a lake based on archival bathymetric maps indicating areas overgrown with rushes and aquatic vegetation was verified. This assessment was assumed to be in accordance with that performed with the official Polish macrophyte-based method for lake assessment (Ecological State Macrophyte Index, ESMI). The study was conducted on Lake Dobrąg located in the Warmian-Masurian Voivodeship (surface area - 108 ha, maximum depth - 27.9 m, mean depth - 11.6 m). It included the hydroacoustic distribution of submerged macrophytes along 85 evenly distributed belt transects (perpendicularl to the shore line), creating a bathymetric chart and maps of vegetation occurrence and identifying areas occupied by hydrophytes (Cmax) and the maximum depth of lake colonization (Z). Analogous data were read from archival bathymetric chart dating from 1964-1968. The values obtained were compared with the means (and their confidence intervals) of 83 stratified lakes in Poland in different ecological status classes. Analysis of changes indicated that the ecological status of the lake had deteriorated. In the mid-1960s, the status of the lake was less than “very good” while the current status borders between “good” and “moderate.” The results indicate that the proposed method could be useful when attempting to assess changes in ecological status using archival bathymetric charts showing areas overgrown with vegetation and the distribution of it in lakes.
Biological characteristics of the round goby, Neogobius melanostomus (Pallas, 1814), from different water bodies
Authors: Demchenko Viktor O. , Tkachenko Maria Y. 
Published: May 2017

Abstract
The paper considers the ecological variability of the round goby, Neogobius melanostomus (Pall.), in different environments. The dietary spectrum and morphological variability of round goby populations were studied in two water bodies with different environmental conditions. The sizes and body weights of specimens were the largest in Obytichna Bay and the smallest in Kakhovka Reservoir. Differences in the morphological indices of gobies from freshwater and marine bodies of water were determined using discriminant analysis. At the study sites the round goby chiefly fed on benthic organisms that varied in species composition and energy equivalent. A significant portion of the diet comprised bivalves such as Abra ovata, Cerastoderma glaucum, and Parvicardium exiguum, which have the highest energy capacity. The average energy equivalent indices of prey items were higher in Obytichna Bay and the lowest in Kakhovka Reservoir.
Achieving epistemic alignment in a psycholinguistic experiment
Authors: Kobayashi Hillman Kyoko , Ross Steven J. , Kasper Gabriele 
Published: May 2017

AbstractA critical condition for obtaining valid data in a psycholinguistic experiment is that the participants understand how to perform the experimental tasks. Participants usually are not familiar with the organization and requirements of the experiment and are therefore given instruction and often practice opportunities prior to the actual test trials. Pre-experimental instruction is a regular component of the experimental set-up, yet no research exists on how the activity is organized with a view to its purpose in the research context and as the experimenter’s and participant’s joint interactional project. This case study is the first to begin to fill the gap. The instruction in focus aimed at preparing the participant to take part in a reaction time experiment designed to measure the implicit grammatical knowledge of L2 speakers of English. Building on ethnomethodological and conversation-analytic research on instruction delivery and understanding displays in different settings, the analysis reveals how in the course of the instruction the asymmetric epistemic statuses (Heritage 2012) of researcher and participant were incrementally aligned as they collaboratively accomplished explanation sequences and worked through practice items. It also shows how both participants selectively referenced the onscreen written instructions and how these became resources for the experimenter’s explanations and the participant’s evolving understanding of the experimental requirements. The main goal of this paper is to bring an unexamined but indispensable component of the experimental research process to applied linguists’ attention and encourage further studies in this area. A further intention is to explore pre-experimental instruction practices in a larger archive of task instructions and eventually empirically test whether the interaction during instruction delivery is at all related to variation in the reaction times as measures to operationalize cognitive processes.
Making Secular Sense of the Sacred
Authors: Fleischacker Sam 
Published: May 2017

Abstract
From the earliest days of social science, in the writings of David Hume and Adam Smith, it has been difficult to make secular sense of the notion of sacredness in terms that believers in that notion can recognize as what they mean by it-social scientists instead tend almost universally to treat it as the consequence of an illusion of some kind. This paper explores the sources of that difficulty, arguing that it is built into the assumptions that make social science a science at all. It also argues that treating a category so central to the moral thinking of millions of people as resulting from an illusion breeds attitudes of condescension that are morally problematic. Using themes to be found especially in Kant, the paper proposes a way for social scientists to treat the category of sacredness with respect for moral purposes even while maintaining the presuppositions, for the purposes of their scientific work, that lead them to try to explain it away.
Traditional Morality and Sacred Values
Authors: McPherson David 
Published: May 2017

Abstract
This essay gives an account of how traditional morality is best understood and also why it is worth defending (even if some reform is needed) and how this might be done. Traditional morality is first contrasted with supposedly more enlightened forms of morality, such as utilitarianism and liberal Kantianism (i.e., autonomy-centered ethics). The focus here is on certain sacred values that are central to traditional morality and which highlight this contrast and bring out the attractions of traditional morality. Next, this essay explores and offers support for the convergence thesis to which traditional morality, understood as common morality, is committed. This thesis states that although there are diverse moral traditions, insofar as they are in good order we should expect them to converge upon a common or universal morality, even if there remain some differences in the details. The defense of this thesis provides justification for the validity of traditional morality as it suggests an objective basis.
Sacred Values and Interreligious Dialogue
Authors: Schneider Hans Julius 
Published: May 2017

Abstract
The paper develops a perspective on religion that is inspired by William James’ concept of religious experience and by the philosophy of language of the later Ludwig Wittgenstein. It proceeds by naming basic steps leading to the proposed conception and by showing that none of them must be a hindrance for a substantial understanding of religion. Among the steps discussed are the acceptance of non-theistic religions, an existential version of functionalism, and the acceptance of the possibility of non-literal truths about the human condition. Furthermore, it proposes a way to interpret the expression ‘the sacred’ in the given framework. Finally it points out two contradictory necessities that make interreligious dialogue difficult: In the beginning one has to use an abstract vocabulary in order not to exclude any positions, but on the other hand one has to avoid robbing the participants of the means for articulating their specific religious views.
Information Acquisition in the Era of Fair Disclosure: An Application of Asymmetric Awareness
Authors: Liu Zhen 
Published: May 2017

AbstractAs the cost of financial information dissemination continues to decline, investors, firms, and regulators are gradually adopting the principle of fair disclosure, which requires no preferential public disclosure. We use a simple model to examine the impact of this change on information acquisition with two alternative assumptions: (1) Investors have symmetric awareness about the underlying uncertainties, or (2) this awareness is asymmetric among them. Under the first assumption, the change reduces information asymmetry among investors and induces acquisition of high-quality information. Under the second assumption, however, the reduction of information asymmetry may be limited, and information acquisition is either reduced or less efficient. Specifically, investors with high awareness may either acquire high-quality information at a higher cost or not acquire it; investors with low awareness only acquire low-quality information. The loss in overall information quality is greater when awareness asymmetry is moderate than when it is high or low; this causes information asymmetry between the insiders and outside investors as a whole. These results offer explanations for intriguing empirical findings regarding the effect of a recent accounting regulation (Regulation Fair Disclosure).

Study on Hydration and Strengthening of High Alumina Cements
Authors: Angelescu Nicolae , Stancu Cristina , Amziane Sofiane , Bratu Vasile , Stoian Elena Valentina 
Published: May 2017

Abstract
Refractory concretes based on aluminous cements are used with great success in areas where high temperatures are required. The mineralogical composition of the high alumina cement is the main factor which gives the physical and mechanical properties at high temperatures of refractory monolithic materials.
It is therefore desirable to use high alumina cements based on mineralogical compounds with high refractoriness, because in the end those beneficial properties can be found in the final product - refractory concrete.
The aim of this paper is to design, realize and characterize different compositions of high alumina cements based on mineralogical compounds with the highest refractory from the CaO-Al2O3 binary system (i.e. CA, CA2, and CA6), and to find ways of hydraulic activation of calcium hexa aluminate, also.

Its main goal is to overcome the limitations of classical BPM by applying social software principles within the BPM lifecycle. Since BPM is a holistic discipline it is important to also include cultural and social aspects into BPM studies. Objectives: The main aim of this paper is to examine the link between organizational culture, social software usage and BPM maturity in the observed company. Methods/Approach: A case study methodology has been used for this study. An interview has been conducted in combination with a survey approach. Results: Results of the research revealed a high usage of social BPM within the observed company in combination with a high level of BPM maturity and a clan organizational culture. Conclusions: The observed IT company has knowledge intensive processes and uses social BPM to deal with the process change and optimization. The clan culture is, by its characteristics, a favourable organizational culture for social BPM.
A Multi-Country Trade and Tourism with Endogenous Capital and Knowledge
Authors: Zhang Wei-Bin 
Published: May 2017

AbstractBackground: The study models a dynamic interaction among economic growth, structural change, knowledge accumulation, international trade and tourist flows. Objective: The purpose of this study is to introduce endogenous knowledge into a multi-country growth model with trade and tourism proposed by Zhang. The study models a dynamic interaction among economic growth, structural change, knowledge accumulation, international trade and tourist flows. Methods/Approach: The model is based on Arrow’s learning by doing, the Solow one-sector growth model, the Oniki-Uzawa neoclassical trade model, and the Uzawa two-sector growth model. We first build the multi-country neoclassical growth model of endogenous knowledge with international tourism. Then we show that we can follow the motion of the J - country world economy with J + 1 differential equations. Results: We simulate the motion of the three-country global economy. We carry out a comparative dynamic analysis by simulation with regard to the knowledge utilization efficiency, the efficiency of learning by doing, the propensity to save, the propensity to tour other countries, and the population. Conclusions: The global economy has a unique equilibrium.
New Banks’ Business – Rating Competence for the Real Sector
Authors: Meeh-Bunse Gunther , Hermeling Anke 
Published: May 2017

Abstract
Background: The global financial crisis has revealed the urgency of changes in the business models of banks around the world. Due to rising regulatory costs and the effects of the low-interest rate phase, the revenue of banking sector is under pressure. Banks have to generate new sources of revenue. A conceivable externalization of bank internal rating data is appropriate. This available knowledge has a potential to generate new business potentials. Objectives: The goal of this paper is to compare the procurement of internal ratings by credit institutions and the supplier evaluation, particularly regarding the assessment of their financial capacity, as well as the identification of potential interfaces. Methods/Approach: The methods used in the research included an example-oriented presentation and an analysis of indicator systems aimed at assessing the financial soundness within the internal rating by credit institutions and the supplier evaluation. Results: Results show the intersections between the two evaluation systems. Conclusions: Despite the determination of evaluation results by their objective function, apparently significant trends of financial (dis)soundness can be recognized as a part of the two evaluating systems. This result provides starting points to initiate the discussion about a possible (partial) externalisation of internal ratings by credit institutions to be used for the supplier evaluation.
Negotiation of meaning and language-related episodes in synchronous, audio-based Chinese-German eTandem
Authors: Renner Julia 
Published: May 2017

Abstract
The present paper examines negotiation of meaning and language-related episodes in Chinese-German eTandem interaction, focusing on Chinese as target language. Against the background of the interactionist approach to language learning and drawing upon Swain and Lapkin’s (1998, Interaction and second language learning: Two adolescent French immersion students working together. Modern Language Journal 82. 320–337) concept of “language-related episodes” (LREs), the main focus of this paper is to investigate how negotiation of meaning is undertaken in this particular learning environment, to what extent LREs occur in Chinese-German eTandems, and what the characteristics of these episodes are. Furthermore, differences between novice CFL (Chinese as a Foreign Language) learners and intermediate CFL learners participating in eTandems are identified. The findings show that the participants only use the target languages (Chinese and German) to negotiate meaning. Novice CFL learners rely heavily on code-switching to German, while intermediate learners mainly use Chinese. Compared to negotiation of meaning, LREs occur sparingly and cover word searches and reflections on grammar, pronunciation, and style/expression. Text-chat usage during negotiation of meaning and LREs points to the fact that focus on linguistic form is supported by a switch from oral mode to text-chat.
