Factors explaining the changes in the rankings of Polish cities’ economic position (1992-2013)
Authors: Łukomska Julita 
Published: April 2018

Abstract
A nation’s economic potential is always concentrated within cities. Polish cities were faced with quite radical changes in the last two decades. During this period, some cities saw losses of more and more citizens and were not ready to develop new economic approaches. Other cities were able to attract both people and businesses. The main objective of the article is to identify the changes in the economic position of Polish cities and the factors which were the driving forces behind them (including, in particular, the role of European integration). Results of the conducted regression analyses confirm that it is easier to identify “losing” factors (e.g. dependency on declining industry) than “winning” ones (as they are more individualized and more difficult to capture in statistical models).The availability of EU funds for local governments has been confirmed to be a significant factor explaining the changes in the economic position of Polish cities.
On the alexander dual of path ideals of cycle posets
Authors: Olteanu Anda , Olteanu Oana 
Published: April 2018

Abstract
We consider the Alexander dual of path ideals of cycle posets, and we compute the Castelnuovo-Mumford regularity. As a consequence, we get the projective dimension of path ideals of cycle posets. Our results are expressed in terms of the combinatorics of the underlying poset.

Authors: Ashraf Mohammad , Boua Abdelkarim , Siddeeque Mohammad Aslam 
Published: April 2018

Abstract
In the present paper, we introduce the notion of generalized multiplicative derivation in a near-ring N and investigate commutativity of 3-prime near-rings, showing that certain conditions involving generalized multiplicative derivations force N to be a commutative ring. Finally some more results related with the structure of these derivations are also obtained.

Citizens as smart, active sensors for a quiet and just city. The case of the “open source soundscapes” approach to identify, assess and plan “everyday quiet areas” in cities
Authors: Radicchi Antonella , Henckel Dietrich , Memmel Martin 
Published: April 2018

Abstract Today the so-called “smart city” is connoted by massive implementation of novel, digital technology, which is often considered as the best solution to global issues affecting contemporary cities. Sophisticated and low-cost technological solutions are developed also in the field of noise monitoring and they are expected to play an important role for acousticians, city planners and policy makers. However, the “smart city” paradigm is controversial: it relies on advanced technological solutions, yet it fails to consider the city as a social construct and it often overlooks the role of citizens, in the quest for technological advances and novel methods. This is especially true in the field of smart acoustic solutions addressing the issue of urban quiet areas: main methods and technologies developed so far barely involve citizens and consider their preferences. This contribution tackles this challenge, by illustrating a novel mixed methodology, which combines the soundscape approach, the citizen science paradigm and a novel mobile application - the Hush City app - with the ultimate goal of involving people in identifying, assessing and planning urban quiet areas. Firstly, the theoretical background and the methods applied are described; secondly initial findings are discussed; thirdly potential impact and future work are outlined.
A model for implementing soundscape maps in smart cities
Authors: Kang Jian , Aletta Francesco , Margaritis Efstathios , Yang Ming 
Published: April 2018

Abstract
Smart cities are required to engage with local communities by promoting a user-centred approach to deal with urban life issues and ultimately enhance people’s quality of life. Soundscape promotes a similar approach, based on individuals’ perception of acoustic environments. This paper aims to establish a model to implement soundscape maps for the monitoring and management of the acoustic environment and to demonstrate its feasibility. The final objective of the model is to generate visual maps related to perceptual attributes (e.g. ‘calm’, ‘pleasant’), starting from audio recordings of everyday acoustic environments. The proposed model relies on three main stages: (1) sound sources recognition and profiling, (2) prediction of the soundscape’s perceptual attributes and (3) implementation of soundscape maps. This research particularly explores the two latter phases, for which a set of sub-processes and methods is proposed and discussed. An accuracy analysiswas performed with satisfactory results: the prediction models of the second stage explained up to the 57.5% of the attributes’ variance; the cross-validation errors of the model were close to zero. These findings show that the proposed model is likely to produce representative maps of an individual’s sonic perception in a given environment.
Three phase heat and mass transfer model for unsaturated soil freezing process: Part 1 - model development

Published: April 2018

Abstract
A three-phase model capable of predicting the heat transfer and moisture migration for soil freezing process was developed based on the Shen-Chen model and the mechanisms of heat and mass transfer in unsaturated soil freezing. The pre-melted film was taken into consideration, and the relationship between film thickness and soil temperature was used to calculate the liquid water fraction in both frozen zone and freezing fringe. The force that causes the moisture migration was calculated by the sum of several interactive forces and the suction in the pre-melted film was regarded as an interactive force between ice and water. Two kinds of resistance were regarded as a kind of body force related to the water films between the ice grains and soil grains, and a block force instead of gravity was introduced to keep balance with gravity before soil freezing. Lattice Boltzmann method was used in the simulation, and the input variables for the simulation included the size of computational domain, obstacle fraction, liquid water fraction, air fraction and soil porosity. The model is capable of predicting the water content distribution along soil depth and variations in water content and temperature during soil freezing process.
Therapeutic efficacy of systemic therapy for colorectal peritoneal carcinomatosis: surgeon’s perspective
Authors: Franko Jan 
Published: April 2018

AbstractTreatment choices for colorectal peritoneal carcinomatosis/metastases include systemic therapy and increasingly cytoreductive surgery with intraperitoneal chemotherapy delivery. These options are best considered as complementary and not exclusive alternatives. Two prospective randomized trials support use of peritonectomy procedures and intraperitoneal chemotherapy for colorectal peritoneal carcinomatosis. This overview examines efficacy, limitations and landscape of systemic therapy focusing on colorectal peritoneal carcinomatosis. Observations from literature support notions that (1) systemic therapy provides survival benefit for all prototypical patients with mCRC irrespective of metastatic disease site; (2) the magnitude of this benefit is considerably reduced among patients with peritoneal metastases who consequently experience significantly shorter overall survival; (3) efficacy of systemic therapy improved over time but at a slower pace for those with carcinomatosis; (4) this therapeutic difference has not diminished with introduction of targeted therapy, but perhaps widened; (5) further research of cytoreductive surgery and/or intraperitoneal regional therapies is thus a multidisciplinary responsibility of the entire oncology community; (6) peritonectomy procedures with intraperitoneal regional therapy are not scientifically supported in absence of systemic therapies.
Role of laparoscopy in initial tumour staging in advanced epithelial ovarian cancer: a systematic review
Authors: Zeff Natalia 
Published: April 2018

AbstractBackgroundThe aim of this systematic review was to investigate the accuracy of additional staging laparoscopy (SL) in advanced epithelial ovarian cancer (AEOC) to predict futile laparotomy (FL).MethodsSystematic review according to preferred reporting items for systematic reviews and meta-analyses statement (PRISMA) criteria. Clinical studies investigating the role of SL in selecting women with AEOC for primary debulking surgery (PDS) were included. Index test: SL. Reference test: laparotomy. Target condition: incomplete cytoreduction (CR) with remaining disease<1 cm.ResultsNine prospective and retrospective studies reporting on eight cohorts totalizing 778 LS were included. Reference test was completed in 76 % cases. PPV for FL was between 0.69 and 1.0. In three studies examining the value of a predictive index value (PIV) for predicting FL, sensitivity of the index test (LS with PIV ≥8) was between 46 % and 70 %, and specificity between 89 % and 100 %. The proportion of patients that received CR during PDS differed widely between studies (from 50 to 91). Using a PIV did not increase the sensitivity and might result in more patients receiving FL. In the only randomized trial, FL occurred in 10 (10 %) of 102 patients in the LS group versus 39 (39 %) of 99 patients in the primary PDS group (relative risk, 0.25; 95 % CI, 0.13–0.47; p<0.001). Port-site recurrences occurred in 2%–6 % patients. Overall costs of with or without SL were comparable.ConclusionsThe evidence available from this systematic review supports the inclusion of an additional LS to the conventional initial diagnostic workup in women with AEOC.
Economic aspects of metals recover

Published: April 2018

Abstract
One of the modern economy models is circular economy in which wastes should be considered as resource and used in an efficient and sustainable way. This also concerns to metals included in scraps. However, the need for metal recovery from waste is not only the result of the latest economic trends but also the result of large and constantly changing demand for metals. Shrinking natural sources of metals, concentrations of ores in small number of countries in the world and resulting from this dependence on import, geopolitical situation, new technologies demands are only a few most important determinants that have been changing the structure of the metal market over years. In this chapter, authors focused on the presentation of economic aspects of metal recovery from various sources. The chapter presents the characteristic of metal market elements (supply, demand and price) and changes that took place over decades, underlining the structure of precious and highly desirable metal market elements. Balance between the demand and supply ensures price stability and rationalizes inflation. However, growing demand on many means that secure supply chains, such as recycling and material recovery, are essential to ensure continuity in the supply chain and guarantee unrestricted technological progress and innovation. The data included in this chapter presents also the concentration of different metals and group of metals in wastes pointing that recycling of waste can become one of the possibilities of acquiring missing and critical metals. Metal-laden wastes include a few groups: waste electrical and electronic equipments, catalysts of different application, introduced on chemical, petrochemical or automotive market, galvanic wastes and wastewaters. The profitability assessment of recycling processes is very complicated. Nevertheless cited data shows that profitability of recovery depends on the metal analyzed and the type of waste.
It must be underline that an optimized management of wastes is of a great importance for the global economy and allow achieving not only economic but also environmental and social benefits.
Steuervermeidung und Corporate social responsibility
Authors: Wagner Franz W. 
Published: April 2018

Zusammenfassung
Zahlreiche Großunternehmen dokumentieren im Rahmen ihrer gesellschaftlichen Verantwortung (Corporate social responsibility, CSR) erbrachte Leistungen in CSR-Reports. Wenn eine ausgeprägte CSR-Publizität mit extrem niedrigen Steuerquoten von Unternehmen einhergeht, kann es wie bei Starbucks 2012 in Großbritannien zu Protesten in der politischen Öffentlichkeit kommen: Während Unternehmen bislang Beiträge zum Steueraufkommen nicht zu ihren CSR-Pflichten zählten, erwartet die Öffentlichkeit von ihnen, dass sie freiwillig einen „fairen“ Anteil am Steueraufkommen der Staaten übernehmen, in denen sie ihre Geschäftstätigkeit ausüben; Unternehmen können Reputationsschäden drohen, wenn sie keine „Good corporate citizens“ sind. Franz W. Wagner bezieht deshalb in seinem konzeptionellen Überblick über die umfangreiche CSR-Fachliteratur die Steuerbelastung von Unternehmen mit ein. Er erörtert CSR-Aktivitäten von Unternehmen und steuerfinanzierte Staatstätigkeit als alternative Organisationsformen der Produktion und Finanzierung spezifischer privater und öffentlicher Güter unter Effizienz- und Verteilungskriterien. Im Vergleich zu einer steuerfinanzierten Staatstätigkeit können CSR-Aktivitäten von Unternehmen vor allem wegen ihrer ungünstigeren Verteilungswirkungen nachteilig sein.

AbstractIntroduction: Persons with intellectual disabilities are faced with many obstacles in performing physical activity. The trigger may be coming from genetics, environmental factors (eg. financial), as well as psychological related, inter alia, the level of motivation. The aim of this study was to evaluate the anaerobic performance of the lower limbs of men with intellectual disabilities. Another aim of this study was to compare the anaerobic performance of physically active and inactive men with intellectual disabilities.Material and methods: The participants of the study were 22 physically active men and 9 physically inactive man with intellectual disability. All participants performed a 30-second Wingate test twice. The following parameters were evaluated the mean power (MP), the relative mean power (rMP), the maximum power (PP), the relative maximum power (rPP) and fatigue index (FI). We compared the results obtained in both tests 30-second to examine the reliability and the values obtained in the test between active and inactive persons .Results: The results showed significant correlations between all power parameters studied, except for the fatigue index. All parameters of physically active group with intellectual disabilities achieved significantly better results relative then inactive persons.Conclusions: The reliability of 30-second Wingate test for persons with intellectual disabilities were confirmed. Also confirmed a higher power level inactive men with intellectual disabilities in relation to the untrained men.
Import Determinants and Potential Markets: A Panel Data Gravity Modelling Analysis for Bahrain
Authors: Abbas Shujaat , Waheed Abdul 
Published: April 2018

Abstract
This study investigates macroeconomic determinants of import flow and explores potential import markets for Bahrain using an augmented gravity model on panel data of 42 trading partners, from 2000 to 2016. The result of panel generalized least square estimation technique shows that the core variables support the theory of the basic gravity model. The estimated results of the augmented variables show that the imports of Bahrain are more responsive to income of trading partners, gross domestic product, and export flow; whereas, negatively determined by the relative price. The findings of dummy variables show that there is a significant role of common language and Gulf economic integration on imports of Bahrain. The results of the import potential analysis show that Bahrain has exceeded its import potential from most of its Asian trading partners; however, positive import potential exists in Africa and America and some selected Middle Eastern and European markets.
On “A mutual information estimator with exponentially decaying bias” by Zhang and Zheng
Authors: Zhang Jialin , Chen Chen 
Published: April 2018

Abstract
Zhang, Z. and Zheng, L. (2015): “A mutual information estimator with exponentially decaying bias,” Stat. Appl. Genet. Mol. Biol., 14, 243–252, proposed a nonparametric estimator of mutual information developed in entropic perspective, and demonstrated that it has much smaller bias than the plugin estimator yet with the same asymptotic normality under certain conditions. However it is incorrectly suggested in their article that the asymptotic normality could be used for testing independence between two random elements on a joint alphabet. When two random elements are independent, the asymptotic distribution of

$\sqrt{n}$

n

-normed estimator degenerates and therefore the claimed normality does not hold. This article complements Zhang and Zheng by establishing a new chi-square test using the same entropic statistics for mutual information being zero. The three examples in Zhang and Zheng are re-worked using the new test. The results turn out to be much more sensible and further illustrate the advantage of the entropic perspective in statistical inference on alphabets. More specifically in Example 2, when a positive mutual information is known to exist, the new test detects it but the log likelihood ratio test fails to do so.
Local/import – and foreign currency prices: inflation, uncertainty and pass through endogeneity
Authors: Herwartz Helmut , Roestel Jan 
Published: April 2018

Abstract
We investigate first and second order moment interactions among import prices (IPs), local currency prices (LCPs) and producer currency prices (PCPs) for 20 (mostly) developed economies and a time period of 3 decades. We test various hypotheses on both linear and non-linear effects put forth in the literature on the endogeneity of exchange rate pass through to monetary policy. It turns out that PCP shocks give rise to IP uncertainty in a sizeable manner, while the further propagation of IP uncertainty to LCP inflation uncertainty is moderate. Moreover, LCP inflation uncertainty increases the uncertainty of IP inflation (measured in local currency). In general, both inflation and its uncertainty are diagnosed as core determinants of pass through variation. Thus, a lack of monetary credibility could serve as a catalyst for the import of foreign price pressures and uncertainty to local prices.
Modeling changes in US monetary policy with a time-varying nonlinear Taylor rule
Authors: Nguyen Anh D. M. , Pavlidis Efthymios G. , Peel David A. 
Published: April 2018

Abstract
The monetary economics literature has highlighted four issues that are important in evaluating US monetary policy since the late 1960s: (i) time variation in policy parameters, (ii) asymmetric preferences, (iii) real-time nature of data, and (iv) heteroskedasticity. In this paper, we exploit advances in sequential monte carlo methods to estimate a time-varying nonlinear Taylor rule that addresses these four issues simultaneously. Our findings suggest that US monetary policy has experienced substantial changes in terms of both the response to inflation and to real economic activity, as well as changes in preferences. These changes cannot be captured adequately by a single structural break at the late 1970s, as has been commonly assumed in the literature, and play a non-trivial role in economic performance.
Seelsorge in neuen Kontexten

Published: April 2018

ZusammenfassungReligiöse/spirituelle Begleitung ist Aufgabe des multiprofessionellen Palliativteams. Seelsorgende mit kirchlichem Auftrag gehören in der Regel zu stationären Palliativteams. Die Mitarbeit der Seelsorge im ambulanten Bereich ist hingegen eher sporadisch und zufällig. In der vorgestellten Studie werden bestehende Formen der Mitarbeit kirchlicher Seelsorge in Teams der spezialisierten ambulanten Palliativversorgung (SAPV) im Bundesland Bayern untersucht. Es wurden 34 semistrukturierte Interviews mit Mitgliedern von 12 SAPV Teams (jeweils 6 mit/ohne Seelsorger/-in im Team) in Bayern geführt. Interviewt wurden 12 Ärzte bzw. Ärztinnen, 12 Pflegende, 4 Sozialarbeiter/-innen und 6 kirchliche Seelsorgende. Es zeigte sich, dass Spiritualität im Kontext der SAPV-Versorgung eine relevante Größe darstellt. Die Bereitschaft zu Spiritual Care ist bei Teammitgliedern unterschiedlich ausgeprägt, wobei sich der persönliche Bezug zu spirituellen Fragen förderlich auswirkt. Die Mitarbeit von Seelsorgenden im Team fördert die spirituelle Kompetenz der Teammitglieder und stellt eine Entlastung für das Team dar. Spiritual Care bildet eine Schnittstelle zwischen der „profanen“ naturwissenschaftlich und ökonomisch orientierten Logik des Gesundheitswesens und der religiös geprägten kirchlich verantworteten Seelsorge. Mit der daraus resultierenden Spannung gilt es im Blick auf das gemeinsame Ziel der Versorgung von Patienten und Zugehörigen konstruktiv umzugehen.
