Facilitation in popular music education
Authors: Cremata Radio 
Published: February 2017

Abstract
This article explores the evolving role of facilitators in popular music education contexts, building on research in music education related to a range of topics such as calls for reform, informal learning, experiential learning, popular music and technology based music learning contexts. A popular music education facilitator employs constructivist learning approaches through student-centred experiential processes. A series of case studies were conducted at various schools including middle schools, high schools and post-secondary contexts. Participants’ classroom management styles ranged from from low-control to high-control facilitation. Student perspectives indicated that facilitation promoted democracy, autonomy, diversity, hospitality, differentiation, exploration, creativity, collaboration and inclusivity. The findings and implications of this research apply to the music education profession, calling into question foundations of student-centred learning, autonomy and increased student agency in music learning contexts.
Through the looking glass: A study of the role of reflection in the musical development of popular music undergraduates at the University of Liverpool
Authors: Esslin-Peard Monica 
Published: February 2017

Abstract
Much has been written about musical practice and performance, with little consensus over what practice means, or how musicians progress by practising. Studies have focused primarily on individual Western classical musicians in the conservatoire, with more recent research turning to popular, jazz and folk musicians. Informal and collaborative practices are central in popular musicians’ learning. The current research project focuses on the practice and performance of undergraduate popular musicians, described in students’ reflective essays. This article presents highlights in the musical development of one cohort of popular musicians over the 3 years of their study, including examples of practice behaviours, development of technique, collaboration with band members through rehearsals, creating original material, and gigging on and off campus. Findings indicate the possible role of reflection to support musical development of students, motivated by membership of bands and increasing technical prowess, linked to set lists and band aspirations to perform off-campus.
The longer revolution: The rise of vernacular musics as ‘new channels of general learning’
Authors: Wright Ruth 
Published: February 2017

Abstract
This article takes as its point of origin an extract from Apple’s (2013) book Can Education Change Society? Beginning with the concept of ‘radical democratic egalitarianism’ the author examines the extent to which many current models of music education meet the criteria for ‘robust egalitarianism’ with reference to their inclusion of popular culture. With reference to Williams’ (1961) seminal work in cultural studies The Long Revolution, consideration is given to the extent to which progress towards cultural, musical democracy has been made in music education. These considerations are juxtaposed against the thought of key sociological theorists Apple; E. O. Wright; Bourdieu; Marx and Engels; and Day. The article then discusses research in the area of youth and popular music and surveys international approaches to popular music education. Finally the article turns to pedagogical considerations in relation to popular music. Utilizing Bennett’s (2000) assessment of popular music as one of the primary cultural resources of contemporary social life for young people, an analogy is drawn between Williams’ heralding of the democratic benefits of the introduction of vernacular language as the new channel of general instruction and the possibilities of extending popular music as the new channel of general musical learning. It is suggested that such a change might move the Long Revolution forward in music education and in the cultural lives of young people.

Impact of internal migration movements on the schooling process in Turkey: Supervisors’ views
Authors: Akar Hanife , Şen Derya 
Published: February 2017

This study attempted to examine the impact of interregional and urban–rural population movements on schools located in areas subjected to high in-migration and out-migration flows in Turkey based on data collected from primary school supervisors (N=150). A cross-sectional survey design was utilized to examine the most pressing problems confronted in those schools, and possible actions that could be taken by various stakeholders were sought. Overall data suggest that those schools serve mostly disadvantaged populations with poor households. Among the main challenges revealed are lack of adequate school resources and poor facilities, problems caused due to ineffective and untimely implementation of the program, high personnel turnover and recruitment of largely inexperienced and relatively less qualified educational staff, and lower levels of parental involvement in children’s schooling. Accordingly, proposed recommendations focused on measures to eliminate capacity and resource constraints, improve hiring practices, and secure adequate supervision and support for educational staff, meet academic and socio-emotional needs of students and facilitate parental involvement in the education of children.

Published: February 2017

AbstractThis paper deals with the synthesis and characterization of a novel group of potential photocatalysts, based on sol-gel-derived MgO-ZrO2oxide material. The material was synthesized in a typical sol-gel system using organic precursors of magnesia and zirconia, ammonia as a promoter of hydrolysis and methanol as a solvent. All materials were thoroughly analyzed, including morphology and particle sizes, chemical composition, identification of characteristic functional groups, porous structure parameters and crystalline structure. The proposed methodology of synthesis resulted in obtaining pure MgO-ZrO2oxide material with micrometric-sized particles and a relatively high surface area. The samples underwent an additional calcination process which led to the crystalline phase of zirconia being formed. The key element of the study was the evaluation of the effectiveness of decomposition of C.I. Basic Blue 9 dye. It was shown that the calcined materials exhibit both satisfactory adsorption and photocatalytic activity with respect to the decomposition of a selected model organic impurity. Total dye removal varied in the range of 50-70%, and was strongly dependent on process parameters such as quantity of photocatalyst, time of irradiation, and the addition of promoters.
Therapeutic Drug Monitoring in Rheumatic Diseases
Authors: NG Hoi-Yan Alexandra , Mok Chi Chiu 
Published: February 2017

Abstract
The ultimate goal of treating rheumatic disease is to achieve rapid suppression of inflammation, while at the same time minimizing the toxicities from rheumatic drugs. Different patients have different individual pharmacokinetics that can affect the drug level. Moreover, different factors, such as renal function, age or even different underlying diseases, can affect the drug level. Therefore, giving the same dosage of drugs to different patients may result in different drug levels. This article will review the usefulness of therapeutic drug monitoring in maximizing drug efficacy, while reducing the risk of toxicities in Hydroxychloroquine, Mycophenolate Mofetil, Tacrolimus and Tumor Necrosis Factor inhibitors (TNF Inhibitors).

Published: February 2017

Abstract
Small GTP-hydrolyzing enzymes (GTPases) of the RhoA family play manifold roles in cell biology and are regulated by upstream guanine nucleotide exchange factors (GEFs). Herein, we focus on the GEFs of the Vav subfamily. Vav1 was originally described as a proto-oncogene of the hematopoietic lineage. The GEFs Vav2 and Vav3 are more broadly expressed in various tissues. In particular, the GEF Vav3 may play important roles in the developing nervous system during the differentiation of neural stem cells into the major lineages, namely neurons, oligodendrocytes and astrocytes. We discuss its putative regulatory roles for progenitor differentiation in the developing retina, polarization of neurons and formation of synapses, migration of oligodendrocyte progenitors and establishment of myelin sheaths. We propose that Vav3 mediates the response of various neural cell types to environmental cues.
Oral self-translation of stand-up comedy and its (mental) text: a theoretical model
Authors: Palmieri Giacinto 
Published: February 2017

AbstractThis paper investigates the phenomenon of stand-up comedians performing in more than one language, which poses the question of whether and how they translate their material. Past research on stand-up comedy underlines its conversational nature, sometimes at the expense of recognizing its content. Empirical evidence collected from interviews with bilingual stand-up comedians, on the other hand, suggests that they perform a form of oral self-translation, which implies atertium comparationis, the transfer of content. The notion ofmental text, borrowed from ethnography, is then productively used to define this content. As is then suggested, two types of memory, namelydeclarativeandprocedural, are involved in the memorization of this mental text. The declarative part accounts for what is repeatable across performances and is the part involved in conscious translation; its minimal content is identified in the punch lines. The procedural part accounts for variation, improvisation and interaction. A model of the oral-self translation process of stand-up is then proposed. I conclude that re-focusing on the (mental) text of stand-up comedy can offer a better understanding of its translation, which in turn can contribute to a better understanding of humor in a multilingual and multicultural context in future research.
Manipulating humor styles: Engaging in self-enhancing humor reduces state anxiety
Authors: Ford Thomas E. , Lappi Shaun K. , O’Connor Emma C. , Banos Noely C. 
Published: February 2017

Abstract
We conducted three experiments to determine if engaging in self-enhancing humor can alleviate state anxiety associated with an anticipated stressful event. In all three experiments, participants imagined they were about to take a stressful math test. In Experiment 1 participants who engaged in self-enhancing humor while anticipating taking the test experienced less state anxiety than those who engaged in self-defeating humor or no humor at all. Experiment 2 demonstrated that engaging in self-enhancing humor reduced state anxiety more than mere instructions to adopt a non-serious, humorous outlook in the stressful situation. Experiment 3 revealed that self-enhancing humor alone induced participants to adopt a humorous perspective on the stressful math test, but that participants responded with the least state anxiety when they were also given instructions about how to use the humor to reframe the math test. Collectively, our findings corroborate and extend previous correlational studies showing that self-enhancing humor can alleviate state anxiety associated with a stressful event.

Published: February 2017

Abstract
The effect of different sugar types on the sensory characteristics of Maillard reaction products (MRPs) obtained from sunflower protein hydrolysates was evaluated. MRPs were prepared at 120 °C for a time of 2 h and a pH of 7.4. Results showed that the browning intensity, colour development and free and total amino acids of MRPs were highly affected by the sugar types. Peptide-xylose-cysteine (PXC) were more dark-brown in colour with lower free and total amino acid (FAA and TAA) content compared to the other MRPs. However, PXC showed great mouthfulness and continuity taste with stronger meat-like flavour and umami taste compared to MRPs. MRPs from hexose except PGaC, showed acceptable mouthfulness and continuity taste while PLC and PMC and PGaC showed higher caramel-like flavour and bitter taste. Furthermore, pentose sugars (xylose) were the great precursor of sulphur-containing compounds. It could be concluded that sunflower peptides, xylose, cysteine model system could be a good precursor of flavour enhancers.

Abstract

Health problem
The prevalence of low back pain ranges from 74 to 85%, almost everybody in Germany suffers from low back pain once in his or her life. The recurrence rate within twelve months is 62%, which often leads to inability to work and reduction in earning capacity. The rate of chronic manifestation of low back pain is 5%. Subsequent loss of mobility and functional disability lowers quality of life and participation in private life and at work.

Evidence
A recent Cochrane review (Kamper et al., 2014) analysed six (outcome disability) and seven (outcome pain) studies with 722 and 821 participants respectively and showed that multidisciplinary rehabilitation compared to usual care has a small, but clinically relevant effect (pain: SMD -0,21 [CI 95% -0,37; -0,04]; disability: SMD -0,23 [CI 95% -0,4; -0,06]). There is a lack of evidence about the intervention conception, patient-centred outcomes and the cost effectiveness.

Implication for research
Prior to a randomised controlled trial a feasibility study about individualised multidisciplinary biopsychosocial rehabilitation compared to usual care considering people with chronic low back pain at employable age in Germany is needed. The applicability of available manuals, patient-centred outcomes and cost effectiveness should be explored.

Abstract

Background and objective
Foot and ankle surgery is increasing due to demographic and lifestyle changes. Most often, patients are required to unload their foot postoperatively, resulting in signifcant impairment of activities of daily living without adequate preparation for this situation. The aim of the study was the development and evaluation of a preoperative patient education intervention.

Methods
Based on current research, a patient education intervention was developed. To investigate immediate effects, a longitudinal study with two points of measurement before and after the education session was conducted. Outcomes were increase in knowledge, satisfaction and preoperative anxiety, which were measured with a selfdeveloped questionnaire. Additionally, five short interviews were conducted.

Results
56 patients (63% female) with a mean age of 56,7 (SD=14,8) years were included. Patients had a signifcant increase in knowledge following the intervention from mean 3,93 (SD=1,78) to 5,48 (SD=2,29) correctly answered questions (out of 10). Patients felt that they were better informed and more satisfied with the information provided. Patients evaluated the way of information delivery, the content of information, the group and the location as positive.The expectations of patients relating to postoperative load-bearing capacity and coping with everyday life as well as preoperative anxiety did not change following the intervention.

Conclusion
The education intervention could be implemented in the clinical routine and showed positive effects. However, regarding realistic expectations and preoperative anxiety no change was observed. Long-term post operative effectivity and effciency of patient education should be further examined within a randomized controlled trial.
Performance Investigation of Different Modulation Schemes in RoF Systems under the Influence of Self Phase Modulation
Authors: Nain Abhimanyu , Kumar Suresh 
Published: February 2017

Abstract
The Radio over Fiber (RoF) system has emerged out a promising solution to the last mile connectivity along with higher data rates making it the preference for future communication networks. But fiber nonlinearities induce crosstalk and degrade the performance of the system. This paper presents a simulative investigation & comparison of Mach Zehender Modulator (MZM) and Optical Phase Modulator (OPM) including the effects of Self Phase Modulation. A single channel RoF system has been designed using MZM and OPM respectively. The model is analyzed for different ranges of dispersion and input channel power. It is observed that as the dispersion modulus increases the SPM induced pulse broadening also increases. The pulse broadening also increases with increase in the channel input power. Further it is revealed that MZM offers 0.3 dB more channel output power compared to OPM when dispersion is increased from 2 to 10 ps/nm/km. With the increase in channel input power from 10 to 17.5 dBm, OPM suppress SPM effects better than MZM and provides 2 dB more channel output power.

Abstract

Background
Diffusion kurtosis imaging (DKI) allows for assessment of diffusion influenced by microcellular structures. We analyzed DKI in suspected low-grade gliomas prior to histopathological diagnosis. The aim was to investigate if diffusion parameters in the perilesional normal-appearing white matter (NAWM) differed from contralesional white matter, and to investigate differences between glioma malignancy grades II and III and glioma subtypes (astrocytomas and oligodendrogliomas).

Patients and methods
Forty-eight patients with suspected low-grade glioma were prospectively recruited to this institutional review board-approved study and investigated with preoperative DKI at 3T after written informed consent. Patients with histologically proven glioma grades II or III were further analyzed (n=35). Regions of interest (ROIs) were delineated on T2FLAIR images and co-registered to diffusion MRI parameter maps. Mean DKI data were compared between perilesional and contralesional NAWM (student’s t-test for dependent samples, Wilcoxon matched pairs test). Histogram DKI data were compared between glioma types and glioma grades (multiple comparisons of mean ranks for all groups). The discriminating potential for DKI in assessing glioma type and grade was assessed with receiver operating characteristics (ROC) curves.

Results
There were significant differences in all mean DKI variables between perilesional and contralesional NAWM (p=<0.000), except for axial kurtosis (p=0.099). Forty-four histogram variables differed significantly between glioma grades II (n=23) and III (n=12) (p=0.003−0.048) and 10 variables differed significantly between ACs (n=18) and ODs (n=17) (p=0.011−0.050). ROC curves of the best discriminating variables had an area under the curve (AUC) of 0.657−0.815.

Conclusions
Mean DKI variables in perilesional NAWM differ significantly from contralesional NAWM, suggesting altered microstructure by tumor infiltration not depicted on morphological MRI. Histogram analysis of DKI data identifies differences between glioma grades and subtypes.
Effects of Non-axisymmetric Casing Grooves Combined with Airflow Injection on Stability Enhancement of an Axial Compressor
Authors: Dinh C. T. , Kim K. Y. 
Published: February 2017

AbstractThis paper presents a performance evaluation of non-axisymmetric casing grooves combined with airflow injection in a transonic axial compressor with NASA Rotor 37, using three-dimensional Reynolds-averaged Navier-Stokes equations with the k-ε turbulence model. An axisymmetric casing groove was divided circumferentially into 36 non-axisymmetric grooves. The numerical results for adiabatic efficiency and total pressure ratio were validated with experimental data. A parametric study for stall margin, stable range extension, peak adiabatic efficiency, and total pressure ratio at peak adiabatic efficiency of the compressor was performed using five parameters: the front and rear lengths, the height of the casing groove, the injection mass flow rate, and the injection angle. The non-axisymmetric casing grooves combined with injection improve greatly the stall margin and stable range extension of the transonic axial compressor, but reduce only slightly the peak adiabatic efficiency in all cases, compared to the results for a smooth casing.
