Bonsai pedagogy at the service of the coloniality of being and of musical knowledge. An autoethnographic perspective study
Authors: Castro Sebastián Tobías 
Published: January 2018

This paper discusses the musical epistemology concomitant with an ontology of music centred on music as an object, both foundations of the hegemonic musical theoretical/pedagogical model: the conservatory model. In particular, it is proposed to investigate the scope and limitations of some of the categories derived from the privileged object-text of this ontology: the score, and its incidence in the processes of musical significance in which early undergraduate students participate. In this direction, it is intended to show how these musical epistemology and ontology deal only with partial aspects of the musical experience, while at the same time making others invisible or subordinate. Finally, it tries to highlight other ontologies of music, such as action and participation. This research and discussion is based on the analysis of a classroom experience led by the author, with support in the ideas of pedagogy of potency, non-parametral didactics and Bonsai pedagogy by Estela Quintar and Hugo Zemelman and Coloniality of Power, Being and Knowledge proper to the decolonial perspective.
Knowledge and beliefs of politics teachers at German Gymnasien: Findings of a study
Authors: Weisseno Georg , Böker Eva , Oberle Monika 
Published: January 2018

Abstract
Political didactics is a field that has long resisted examination of teaching efficacy. Of particular importance are questions concerning what teaching personnel know and where their content-based expert knowledge comes from, what is to be taught and how teachers deal with problems in understanding content. Teachers’ professional knowledge can be divided into ‘content knowledge’ (CK), ‘pedagogical content knowledge’ (PCK) and pedagogical knowledge. Beliefs regarding teaching and learning processes, pupils have active or passive, receptive or constructive roles ascribed to them. These roles are generally distinguished as the basic positions of constructivist and transmission-based concepts of teaching and learning. This study collected the results for German gymnasium teachers (N=196). 38.6 per cent of respondents were female, on average the age of respondents stands at 43.5 years old (SD=11.4). The assumptions about the structure of subject-specific professional knowledge are checked by comparing a one-dimensional IRT model with various multidimensional ones. The model comparison shows a statistically significant model improvement for the two-dimensional model distinguishing between CK and PCK. PCK can be divided into normative political didactic discourses in one dimension and lessonbased items in a second dimension. Investigation of the structural assumptions shows that politics teachers’ beliefs on teaching and learning can be integrated into overlapping belief syndromes. Cognitive constructivist orientations go hand in hand with greater subject interest, while transmission-based orientations tend to be related to less interest in politics. There is a slightly significant small negative correlation between a constructivist orientation and lesson-based knowledge (LBK). Those who have been teaching for a long time attain lower scores in the subject-specific didactic part of the test. Participation in further training only has an impact on normative and not on LBK.
Microfinance: Viable Approaches for Islamic Banking Implementation
Authors: Jusoh Wan Noor Hazlina Wan , Shariff Anita Md. 
Published: January 2018

Islamic banks have very much engaged in debt financing businesses the same way and as much as their conventional counterparts do. Debt financing businesses, as widely implemented, were specifically targeted for and tailored to the needs of middle and upper income group of people. The low income people remain left out and forgotten in most banking businesses while microfinance instruments, which are meant to help the poor and needy, remain unpopular among the banking institutions. There is indeed increasing calls for Islamic banks to seriously consider this type of instrument as part of their religious obligation embedded under their Islamic identity. This paper demonstrated that microfinance instruments are viable for Islamic banks to consider despite the claims that the contracts are less secured and hence, too risky to embark in. A number of microfinance instruments based on Islamic concepts namely Musyarakah, Murabahah, Mudharabah, Ijarah and Qard al-Hassan as well as operational frameworks such as SPV and wakalah, were being proposed and discussed to pave ways for its implementation by the Islamic banks.

Published: January 2018

This paper aims to identify and analyze the volatility of stock returns and the changes of liquidity around the announcement of Shari’ah stock screening published by Otoritas Jasa Keuangan (OJK) and Dewan Syariah Nasional (DSN-MUI). The announcement is consist of stocks that become the constituent of ISSI (Indonesia Shari’ah Stock Index) and the stocks out from ISSI in each period. The number of data are 341 emitens, divided into two categories. The first category was 196 stocks that out from the composition of ISSI, and the second was shari’ah stock from 145 emitens which categorized as part of ISSI from 2011 to 2016. The statistical method (t-test) is used to analyze the change of stock returns and the change of liquidity in 14 days around the announcement (6 days pre- and post announcement). The result shows that Shari’ah compliant stocks over 6 years around the announcement have no difference in return and have negative sign for both the Shari’ah stocks and the stocks out from ISS. It may caused by the intention of Islamic investor which invest their capital based on the compliance of Shari’ah, so the returns do not become the most important one. Interestingly, on the other hand, the liquidity change of stocks which out of ISSI has negative significant difference on the days after the announcement of screening. It indicates that the non-compliant stocks have negative in change of liquidity or have significant liquidity declining after the announcement. Also, in fact Islamic invetors are more concern in the list of stocks that out from ISSI and the stock returns become less important to them than the compliance of investment. Thess findings confirm the issue that the screening is not effecting the expected return of investors. Besides, this study tells that the screening is perceived as important information by the investors in making decisions. Thus, the next studies are needed to investigate the effect of long-term investment on shari’a stock and the factors that influence the shari’a stock return during the period of announcement.
On the Links between Caricatures and Animated Films in Communist Eastern Europe

AbstractThis article analyses and maps the links between caricature and animated film, as well as their development during the post-World War II era, in communist Eastern Europe. The article also deals with the specific nature of animation production under the conditions of political censorship and the utilisation of Aesopian language as an Eastern European phenomenon for outmanoeuvring censorship.
Global Multi-Protagonist Trends in a Local Setting: The Case of Frozen Land and Autumn Ball
Authors: Teinemaa Teet 
Published: January 2018

AbstractThis article explores whether a specifically regional quality can be identified in the following Finnish and Estonian multi-protagonist/network narrative films: Aku Louhimies’ Frozen Land (Paha maa, Finland, 2005) and Veiko Õunpuu’s Autumn Ball (Sügisball, Estonia, 2007). The article begins by providing an overview of the discussion regarding multi-protagonist films - a film form in which several lead characters are commonly connected via accidental encounters. Thereafter, an examination is made of how the form’s widely recognised generic qualities are represented in the Northern and Eastern European examples. As an overview of the discourse illustrates, multi-protagonist film is mainly interested in urban spatiality, contingency and human interconnectedness. It is also shown that these examples from the cinemas of small nations follow global trends rather closely. At the same time, Frozen Land and Autumn Ball can be seen as representing a specifically regional sensibility that is not only interesting in its own right, but which can also be understood as directly influencing the character-action.
The Branding Potential for the Digital Transmission of Live-Operas to the Cinema: An International Comparison of Estonia and Germany
Authors: Roll Julia , Horst Sven-Ove 
Published: January 2018

Abstract
Today, opera houses are confronted by new (global) digital media offers that enable people to remain outside the opera house while attending a live-opera, e.g. via livestreamed opera performances in the cinema. This is a challenge for media managers in these fields because they need to find new ways to work with these new opportunities. Within a cultural marketing context, branding is highly relevant. Based on the brand image approach by Kevin Lane Keller (1993), we use a complex qualitative-quantitative study in order to investigate if, and how, the brand images of live-opera performances and live-streamed operas differ between countries and cultural contexts. By comparing Estonia and Germany, we found that the perception of live-opera is rather a global phenomenon with only slight differences. Furthermore, the ‘classical’ opera performance in an opera house is still preferred, with a corresponding willingness to pay, while the live-streamed opera offer may provide a modern touch. The study may help media managers in adapting their brand management to include new digital product offers and to find targeted differentiation strategies for increasingly competitive markets.

AbstractThe real/atomic structure of single phase homogeneous nanocrystalline Ce0.5Zr0.5O2±δoxides prepared by a modified Pechini route and Ni-loaded catalysts of methane dry reforming on their bases was studied by a combination of neutron diffraction, synchrotron X-ray diffraction, total X-ray scattering and X-ray absorption spectroscopy. The effects of sintering temperature and pretreatment in H2were elucidated. The structure of the mixed oxides corresponds to a tetragonal space group indicating a homogeneous distribution of Ce and Zr cations in the lattice. A pronounced disordering of the oxygen sublattice was revealed by neutron diffraction, supposedly due to incorporation of water into the structure when in contact with air promoted by the generation of anion vacancies in the lattice after reduction or calcination at high temperatures. However, such disordering has not resulted in any occupation of the oxygen interstitial positions in the bulk of the nanodomains.
Thermodynamic Compatibility, Crystallizability, Thermal, Mechanical Properties and Oil Resistance Characteristics of Nanostructure Poly (ethylene-co-methyl acrylate)/Poly(acrylonitrile-co-butadiene) Blends
Authors: Murugan N. , Manoharan Partheban , Nando Golok B. 
Published: January 2018

AbstractThis paper addresses the compatibility, morphological characteristics, crystallization, physico-mechanical properties and thermal stability of the melt mixed EMA/NBR blends. FTIR spectroscopy reveals considerable physical interaction between the polymers that explain the compatibility of the blends. DSC results confirm the same (compatibility) and reveals that NBR hinders EMA crystallization. Mechanical and thermal properties of the prepared EMA/NBR blends notably enhance with increasing the fraction of EMA in the blends. Morphology study exhibit the dispersed particles in spherical shape in the nanometer level. Swelling and oil resistance study have also been carried out in details to understand the performance behaviour of these blends at service condition
Relations of Tourism and Hotel Management with Respect to GDP Growth of Republic of Srpska
Authors: Lazarević Momir 
Published: January 2018

Summary
Tourism is the fastest growing and one of the most profitable industries in the world, with countless opportunities for the economic development of the regions. One should not view tourism and hospitality as separate concepts, since one can neither exist nor can be sustained without the other. A tourist, besides wanting to see and get to know the attractiveness of a place, wants to be offered a satisfactory level of basic (food, accommodation, transport) and additional (entertainment, recreation, shopping. . ) services which will certainly have an influence on his satisfaction and the desire to return. If we don’t turn to socially responsible behavior, we will lose the conditions for the development of tourism, and therefore a possible basis for social and economic prosperity as a result of such a sustainable tourism. Globalisation also appears as a threat of uniformity of everything that surrounds us, because different societies, economies and cultures are increasingly intertwined and thus endanger the identity of one nation, its customs, folklore and overall cultural creativity.

Published: January 2018

Summary
The saving and investment balance can ensure the stability of the financial market. The aim of the study is to analyse the dynamics of the saving-investment balance in the Republic of Moldova and its impact on economic growth. The role and possibilities of attracting foreign investments into fixed assets are presented. The indicator of investment growth with a low level of gross savings is a signal or a harbinger of a decline in economic growth. According to the National Bank of Moldova, legal export of capital from the Republic of Moldova takes only a small part in the process of export of capital. The leading role in the mechanism of transformation of savings into investment should belong to BNM.

AbstractOnitsha is one of the largest commercial cities in Africa with its population growth rate increasing arithmetically for the past two decades. This situation has direct and indirect effects on the natural resources including vegetation and water. The study aimed at assessing land use-land cover (LULC) change and its effects on the vegetation and landscape from 1987 to 2015 using geoinformatics. Supervised and unsupervised classifications including maximum likelihood algorithm were performed using ENVI 4.7 and ArcGIS 10.1 versions. The LULC was classified into 7 classes: built-up areas (settlement), waterbody, thick vegetation, light vegetation, riparian vegetation, sand deposit (bare soil) and floodplain. The result revealed that all the three vegetation types decreased in areas throughout the study period while, settlement, sand deposit and floodplain areas have remarkable increase of about 100% in 2015 when compared with the total in 1987. Number of dominant plant species decreased continuously during the study. The overall classification accuracies in 1987, 2002 and 2015 was 90.7%, 92.9% and 95.5% respectively. The overall kappa coefficient of the image classification for 1987, 2002 and 2015 was 0.98, 0.93 and 0.96 respectively. In general, the average classification was above 90%, a proof that the classification was reliable and acceptable.
Clinical value of ultrasonography in diagnosis of pulmonary embolism in critically ill patients
Authors: Zhu Ran , Ma Xiao-Chun 
Published: January 2018

Abstract
Pulmonary embolism (PE) is a clinical emergency that will increase the mortality if complicated with unstable hemodynamics. Because of its nonspecific clinical symptoms, it’s a great challenge to make a PE diagnosis. The golden standard to diagnose PE is computed tomography of pulmonary artery (CTPA), but a diagnosis of PE also composed of evaluation of PE risk factors, possibilities, and risk stratification. Ultrasonography may detect right ventricle strain related to hemodynamic change, intravascular thrombosis, thrombosis in right heart or pulmonary arteries, pulmonary infarction, and local pleural effusion. Combination of ultrasound and traditional PE possibility evaluation score may further improve the pretest probability of CTPA. A comprehensive ultrasonography may sometimes rule out PE and may disclose other causes for the clinical situations. A heart-lung-vessel-integrated multiorgan ultrasonography can help with the diagnosis of PE and so should be a necessary weapon for the physicians.

Abstract

Background and Objectives
Provisional and culotte are the most commonly used techniques in left main (LM) stenting. The impact of different post-dilation techniques on fluid dynamic of LM bifurcation has not been yet investigated. The aim of this study is to evaluate, by means of computational fluid dynamic analysis (CFD), the impact of different post-dilation techniques including proximal optimization technique (POT), kissing balloon (KB), POT-Side-POT and POT–KB-POT, 2-steps Kissing (2SK) and Snuggle Kissing balloon (SKB) on flow dynamic profile after LM provisional or culotte stenting.

Methods
We considered an LM-LCA-LCX bifurcation reconstructed after reviewing 100 consecutive patients (mean age 71.4 ± 9.3 years, 49 males) with LM distal disease. The diameters of LAD and LCX were modelled according to the Finnet’s law as following: LM 4.5 mm, LAD 3.5 mm, LCX 2.75 mm, with bifurcation angle set up at 55°. Xience third-generation stent (Abbot Inc., USA) was reconstructed and virtually implanted in provisional/cross-over and culotte fashion. POT, KB, POT-side-POT, POT-KB-POT, 2SK and SKB were virtually applied and analyzed in terms of the wall shear stress (WSS).

Results
Analyzing the provisional stenting, the 2SK and KB techniques had a statistically significant lower impact on the WSS at the carina, while POT seemed to obtain a neutral effect. In the wall opposite to the carina, the more physiological profile has been obtained by KB and POT with higher WSS value and smaller surface area of the lower WSS. In culotte stenting, at the carina, POT-KB-POT and 2SK had a very physiological profile; while at the wall opposite to the carina, 2SK and POT–KB-POT decreased significantly the surface area of the lower WSS compared to the other techniques.

Conclusion
From the fluid dynamic point of view in LM provisional stenting, POT, 2SK and KB showed a similar beneficial impact on the bifurcation rheology, while in LM culotte stenting, POT-KB-POT and 2SK performed slightly better than the other techniques, probably reflecting a better strut apposition.
Endoscopic ultrasound-guided pancreatic pseudocyst drainage with lumen-apposing metal stents or plastic double-pigtail stents: A multifactorial analysis
Authors: Ge Nan , Hu Jinlong , Sun Siyu , Linghu Enqiang , Jin Zhendong , Li Zhaoshen 
Published: January 2018

Abstract

Objective
To compare the efficiency of plastic and metal stents for symptomatic pancreatic pseudocyst (PP) drainage and analyze other main associated factors that affect the outcome of drainage therapy.

Method
Rates of technical and clinical success, procedure-related side effects (hemorrhage, stent migration, and cyst rupture), reinterventions, and duration of hospital stay.

Results
There were 52 patients, 40 patients underwent plastic stent placement and 12 patients underwent lumen-apposing metal stent (LAMS) placement. The total rate of technical success was 100%. The total rate of clinical success was 100%. The total rate of adverse events was 7.7% (4/52). On multiple logistic regression analysis, the use of plastic stents (P < 0.05, Exp B = 12.168) and the presence of a large cyst (P < 0.05, Exp B = 1.036) were shown to significantly increase the risk of reintervention. On multivariate linear regression analysis, etiology of pseudocyst (P < 0.05, B = −8.427, −9.785, −5.514) was associated with prolonged hospital stent, while stent type was not shown be a factor (P > 0.05).

Conclusion
Both plastic and LAMSs are proven to be highly efficient in PP drainage. The LAMS is superior in preventing complications such as migration and cyst leakage and reducing the rate of reintervention.

Abstract

Background and Objectives
The Chinese population typically has inadequate folate intake and no mandatory folic acid fortification. Methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) are the two key regulatory enzymes in the folate/homocysteine (Hcy) metabolism. Hcy has been implicated in the pathogenesis of cardiovascular disease. We conducted a meta-analysis to assess whether the MTHFR gene A1298C and the MTRR gene A66G polymorphisms affect Hcy levels in the Chinese population.

Methods
This analysis included 13 studies with Hcy levels reported as one of the study measurements. Summary estimates of weighted mean differences and 95% confidence intervals (CIs) were obtained using random-effect models.

Results
Overall, there were no significant differences in Hcy concentrations between participants with the MTHFR 1298 CC (12 trials, n = 129), AA (n = 2166; β, −0.51 μmol/L; 95%CI: −2.14, 1.11; P = 0.53), or AC genotype (n = 958; β, 0.55 μmol/L; 95%CI: −0.72, 1.82; P = 0.40). Consistently, compared to those with the MTRR 66 GG genotype (6 trials, n = 156), similar Hcy concentrations were found in participants with the AA (n = 832; β, −0.43 μmol/L; 95%CI: −1.04, 0.17; P = 0.16) or AG (n =743; β, −0.57 μmol/L; 95%CI: −1.46, 0.31; P = 0.21) genotype. Similar results were observed for the dominant and recessive models.

Conclusions
Neither the MTHFR A1298C polymorphism nor the MTRR A66G polymorphism affects Hcy levels in the Chinese population.
