Reflections from a Creative Community-Based Participatory Research Project Exploring Health and Body Image with First Nations Girls
Authors: Shea Jennifer M. , Poudrier Jennifer , Thomas Roanne , Jeffery Bonnie , Kiskotagan Lenore
Published: July 2017

In Canada, Aboriginal peoples often experience a multitude of inequalities when compared with the general population, particularly in relation to health (e.g., increased incidence of diabetes). These inequalities are rooted in a negative history of colonization. Decolonizing methodologies recognize these realities and aim to shift the focus from communities being researched to being collaborative partners in the research process. This article describes a qualitative community-based participatory research project focused on health and body image with First Nations girls in a Tribal Council region in Western Canada. We discuss our project design and the incorporation of creative methods (e.g., photovoice) to foster integration and collaboration as related to decolonizing methodology principles. This article is both descriptive and reflective as it summarizes our project and discusses lessons learned from the process, integrating evaluations from the participating girls as well as our reflections as researchers.
The Integrated Use of Audio Diaries, Photography, and Interviews in Research with Disabled Young Men
Authors: Gibson Barbara E. , Mistry Bhavnita , Smith Brett , Yoshida Karen K. , Abbott David , Lindsay Sally , Hamdani Yani
Published: July 2017

In this article we provide a critical reflection on the integrated use of solicited audio diaries, photography, and interviews in a study with disabled young men transitioning to adulthood. In the study, we developed a methodological approach for illuminating the intersectionality of gender, disability, and generation (life stage) identities. Drawing from a critical Bourdieusian perspective, we suggest that rather than producing single or “true” accounts, the combination of methods can be used to elucidate how participants establish, maintain, and reform their identities in everyday practices. Furthermore, we discuss how participants' acts of data creation are analyzable events in themselves, wherein participants do work to establish, maintain, and reform their identities. We conclude with some lessons learned and future directions.
Navigating the Terrain of Lived Experience: The Value of Lifeworld Existentials for Reflective Analysis
Authors: Rich Stephanie , Graham Melissa , Taket Ann , Shelley Julia
Published: July 2017

In qualitative research we are often presented with a tension between having open and fluid interviews to support staying true to the lived experiences of participants and achieving a level of abstraction from the data in order to uncover the essential structures and meanings of that particular lived experience. A way of resolving this tension is through the application of theoretical frameworks. Van Manen's four lifeworld existentials offer a lens through which to explore and navigate disparate interview data and uncover the essences of lived experience, without imposing categories upon the data itself. Drawing on a study exploring the lived experiences of childless women, we explore the process and principles in operationalising the existentials and discuss the potential implications for analysis and findings. The article demonstrates how Van Manen's lifeworld existentials present us with a holistic and valuable method for reflective practice, in coming to understand lived experience.
Use of Participant-Generated Photographs versus Time Use Diaries as a Method of Qualitative Data Collection
Authors: Thompson MaryEllen , Oelker Abigail
Published: July 2017

A small qualitative research study was chosen as a time efficient way to allow students to participate in and complete a research project during a 16-week long semester course. In the first year of the research contribution course, student researchers asked participants with diabetes to complete time use diaries as a part of their initial data collection. The time use diaries were found to be an ineffective way to collect data on self-management of diabetes and were not useful as a basis for subsequent interviews with the participants. A review of the literature suggested reasons for this lack of effectiveness; in particular, participants tend not to record frequently done daily activities. Further review of the literature pointed toward the use of participant-generated photography as an alternative. Subsequent participants were asked to take photographs of their daily self-management of their diabetes for initial data collection. These photographs provided a strong basis for subsequent interviews with the participants. A comparison of the data collected and the emergent themes from the two different methods of initial data collection demonstrated the improved ability to answer the original research question when using participant-generated photography as a basis for participant interviews. The student researchers found the use of participant-generated photographs to elicit interviews with participants in the context of a research contribution course to be effective and enjoyable.
‘Great, she’s super-strong and she can alter time’
Authors: Calvert Bronwen
Published: July 2017

This article examines the character Illyria (Amy Acker) from the television series Angel (1999–2004). It examines Illyria as a representation of the ‘cult’ action heroine, and as a means of creating visual pleasure within the television narrative. In exploring her function within the narrative of Angel, in which her characterisation undercuts some common ways in which the female body is represented on-screen, the essay compares the character with other female action heroes of 1990s to 2000s television series.
Beyond catch-up
Authors: Johnson Catherine
Published: July 2017

The past 5 years have seen a rapid acceleration in the development of online television in the United Kingdom and beyond, with rise in ownership of Internet-connected television sets, smartphones and tablets, increased access to broadband and the growing penetration of transaction and subscription video-on-demand (VoD) services. This article asks how free-to-air terrestrial broadcasters are adapting to a media marketplace in which, according to Ofcom, on-demand television is becoming mass market, through an analysis of ITV Hub – the VoD player for the United Kingdom’s largest free-to-air advertiser-funded broadcaster. Focusing on the mature UK VoD market and the broadcaster whose business model is most threatened by online television, the article combines trade press and textual analysis to demonstrate how ITV has developed a VoD service highly structured by the logics of broadcasting. Centering its analysis on the interface for ITV Hub, the article argues that this increasingly quotidian form of television ephemera offers a vital site through which to understand the changing nature of television as a medium. The article concludes that with contemporary developments in VoD, the distinctions between linear/broadcast and non-linear/on-demand television (flow vs. file, passive viewer vs. interactive user) are breaking down in ways that challenge prevailing arguments that on-demand television can be understood as offering a distinctly different (and more empowered and interactive) experience for viewers.

RFID usage in European enterprises and its relation to competitiveness
Authors: Bach Mirjana Pejić , Zoroja Jovana , Loupis Michalis
Published: July 2017

The radio frequency identification (RFID) is one of the most promising new technologies of modern economy, with a high potential of improving the efficiency and productivity of enterprises. The main goal of this study is to determine the extent of RFID usage in European (EU) countries and to estimate whether there is a relation between countries’ competitiveness and their levels of RFID usage. First, the trend of RFID usage among EU enterprises is analyzed for the years 2009, 2011, and 2014. Second, a cluster analysis is applied with the goal to create homogenous groups of countries according to the RFID application across different industries. Third, countries from different clusters were compared according to their competitiveness in 2014. Results revealed that enterprises in Europe differ substantially according to their RFID usage. Also, RFID usage is not evenly distributed among countries across different industries, since some countries were leaders in RFID usage in one industry while lagging behind in RFID usage in other industries. Finally, countries from clusters with a higher RFID usage level also have a higher level of technological readiness and innovation, while smaller differences were found in business sophistication.
Data that warms: Waste heat, infrastructural convergence and the computation traffic commodity
Authors: Velkova Julia
Published: July 2017

This article explores the ways in which data centre operators are currently reconfiguring the systems of energy and heat supply in European capitals, replacing conventional forms of heating with data-driven heat production, and becoming important energy suppliers. Taking as an empirical object the heat generated from server halls, the article traces the expanding phenomenon of ‘waste heat recycling’ and charts the ways in which data centre operators in Stockholm and Paris direct waste heat through metropolitan district heating systems and urban homes, and valorise it. Drawing on new materialisms, infrastructure studies and classical theory of production and destruction of value in capitalism, the article outlines two modes in which this process happens, namely infrastructural convergence and decentralisation of the data centre. These modes arguably help data centre operators convert big data from a source of value online into a raw material that needs to flow in the network irrespective of meaning. In this conversion process, the article argues, a new commodity is in a process of formation, that of computation traffic. Altogether data-driven heat production is suggested to raise the importance of certain data processing nodes in Northern Europe, simultaneously intervening in the global politics of access, while neutralising external criticism towards big data by making urban life literally dependent on power from data streams.
Time-lapse embryoscopy
Authors: Kovacs Peter
Published: July 2017

Time-lapse (TL) embryo monitoring is the latest technology that is proposed for embryo evaluation and selection for transfer. TL technology enables us to collect significantly more information about the in vitro development of the embryos that can be obtained through the daily-once evaluation under the light microscope. In addition, the embryos do not need to be removed from the culture environment for this. The extra morphokinetic information and the undisturbed culture conditions could both be beneficial for the cultured embryo cohort. Many morphokinetic parameters have been tested in relation to variety of laboratory (e.g. blastocyst development) and clinical (implantation and live-birth rate) outcomes. Most of these studies are retrospective in nature and suffer from methodological problems (heterogeneous patient population, culture conditions not standardized, and small sample size). Several groups attempted to build algorithms, however, have not yet been confirmed externally as attempts so far could not reproduce the expected predictive abilities. Therefore, these algorithms cannot be universally accepted. The latest algorithm proposed for embryo selection was developed based on data from 24 clinics using local stimulation and laboratory procedures. It groups embryos into five categories (KIDScore) based on in and out of range kinetic events. The algorithm was tested in subsets of patients using various fertilization methods or culture conditions and its predictive ability remained the same. The authors, therefore, feel comfortable to recommend it for routine use in any laboratory using TL technology. There is, however, still limited prospective, randomized trial data testing the algorithms. This article reviews TL technology, retrospective and prospective reports on various morphokinetic parameters, and the benefits and shortcomings of currently available algorithms.
Comparison of 30-Day Morbidity and Mortality After Arthroscopic Bankart, Open Bankart, and Latarjet-Bristow Procedures: A Review of 2864 Cases
Authors: Bokshan Steven L. , DeFroda Steven F. , Owens Brett D.
Published: July 2017

Background:

Surgical intervention for anterior shoulder instability is commonly performed and is highly successful in reducing instances of recurrent instability.

Purpose:

To determine and compare the incidence of 30-day complications and patient and surgical risk factors for complications for arthroscopic Bankart, open Bankart, and Latarjet-Bristow procedures.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

All arthroscopic Bankart, open Bankart, and Latarjet-Bristow procedures from 2005 to 2014 from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) prospective database were analyzed. Baseline patient variables were assessed, including the Charlson Comorbidity Index (CCI). Outcomes measures included length of operation, length of hospital stay, need for hospital admission, 30-day readmission, and 30-day return to the operating room. Binary logistic regression was performed for the presence of any complications after all 3 procedures.

Results:

There were 2864 surgical procedures (410 open Bankart, 163 Latarjet-Bristow, and 2291 arthroscopic Bankart) included. There was no significant difference with regard to age ( P = .11), body mass index ( P = .17), American Society of Anesthesiologists class ( P = .423), or CCI ( P = .479) for each group. The Latarjet-Bristow procedure had the highest overall complication rate (5.5%) compared with open (1.0%) and arthroscopic (0.6%) Bankart repairs. The Latarjet-Bristow procedure had significantly longer mean operative times ( P < .001) in addition to the highest 30-day return rate to the operating room (4.3%; 95% confidence interval, 1.2%-7.4%). Smoking status was an independent predictor of a postoperative complication ( P = .05; odds ratio, 8.0) after Latarjet-Bristow.

Conclusion:

Surgical intervention for anterior shoulder instability has a low rate of complication (arthroscopic Bankart, 0.6%; open Bankart, 1.0%; Latarjet-Bristow, 5.5%) in the early postoperative period, with the most common being surgical site infection, deep vein thrombosis, and return to the operating room.
Using Narrative Approach for Anticipatory Grief Among Family Caregivers at Home
Authors: Toyama Hiroko , Honda Akiko
Published: July 2017

Family caregivers of patients with terminal-stage cancer have numerous roles as caregivers, which can influence their anticipatory grief. The purpose of this study was to clarify how talking to family caregivers of patients with terminal illness using the narrative approach can influence such caregivers’ process of anticipatory grief. We conducted the narrative approach as an intervention with two family caregivers several times and qualitatively analyzed their narratives. The results indicated that these family caregivers had two primary roles—family member and caregiver—and that family caregivers felt trapped in their caregiver role. The narrative approach helped them transition into the role needed for coping with the loss.

Case Article—Optimal Movement Plan of Rice in the State of Andhra Pradesh
Authors: Narayanaswami Sundaravalli , Narasimhan Ravichandran
Published: July 2017

The case discusses an optimal movement plan for food grains (rice) by a state sponsored agency, the Food Corporation of India (FCI) in the State of Andhra Pradesh in India. There are five resource locations and eleven demand locations in this distribution network. Resource capacity and demand requirement for the three product (rice) variants at each location are known. There is no storage capacity restriction either in the demand or source location. Information related to rail network, its connectivity, distance in kilometers between origin-destination pairs, cost of transportation per tonne of food grain by rail or road are known. The primary issue is to develop a monthly movement plan to minimize the overall transportation costs subject to meeting the demand-supply restrictions. The total supply available for distribution and the total requirement at various locations are both equal at the product variant and aggregate level. The secondary issue is to develop an alternative movement plan to fulfil the demand requirements at a location, Karimnagar, which does not have a direct rail connection. Few plans are proposed to resolve the issues; the case encourages analysis of the problem situation and evaluation of the alternate resolution plans.

A Simulation-Based Optimization Algorithm for Dynamic Large-Scale Urban Transportation Problems
Authors: Chong Linsen , Osorio Carolina
Published: July 2017

This paper addresses large-scale urban transportation optimization problems with time-dependent continuous decision variables, a stochastic simulation-based objective function, and general analytical differentiable constraints. We propose a metamodel approach to address, in a computationally efficient way, these large-scale dynamic simulation-based optimization problems. We formulate an analytical dynamic network model that is used as part of the metamodel. The network model formulation combines ideas from transient queueing theory and traffic flow theory. The model is formulated as a system of equations. The model complexity is linear in the number of road links and is independent of the link space capacities. This makes it a scalable model suitable for the analysis of large-scale problems. The proposed dynamic metamodel approach is used to address a time-dependent large-scale traffic signal control problem for the city of Lausanne. Its performance is compared to that of a stationary metamodel approach. The proposed approach outperforms the stationary approach. This comparison illustrates the added value of providing the algorithm with analytical dynamic problem-specific structural information. The performance of a signal plan derived by the proposed approach is also compared to that of an existing signal plan for the city of Lausanne, and to that of a signal plan derived by a mainstream commercial signal control software. The proposed method can systematically identify signal plans with good performance.

Authors: Delkhosh Mohammad , Malek Zahra , Rahimi Maryam , Farokhi Zohreh
Published: July 2017

The aim of the present study was to compare the utility of traditional accounting reporting and financial reporting for performance evaluations. Accordingly, the relationship between six ratios of net cash flows, net operating cash flows, cash value added, income after tax, income before tax, and market value added to the book value of total assets and Tobin’s Q ratio as an indicator of performance evaluation were examined. For this purpose, the information of 122 companies listed on Tehran Stock Exchange in the years 2009 to 2014 were used. Besides, linear regression and analysis of variance (ANOVA) were used to analyze the data. The results showed that except for the ratio of net cash flows to the book value of total assets, there was a significant relationship between the other five ratios. In addition, it was noted that cash value added to net operating cash flows had more information content concerning evaluating the firm performance. The results also indicated that net cash flows did not contain information content for evaluating the firm performance. However, the market value added had the maximum information to be used for evaluating the firm performance.

Variations in the fatty acid compositions of the liver and gonad tissue of spiny eel (Mastacembelus mastacembelus) from Atatürk Dam Lake
Authors: Kaçar Semra , Başhan Mehmet
Published: July 2017

Objective

The aim of the study was to investigate quantitative and qualitative fatty acid profiles of the gonad and liver tissue of female Mastacembelus mastacembelus (spiny eel).

Methods

Total lipids were extracted with 5 mL of chloroform-methanol (2:1 v/v). Samples containing gonad and liver lipid were transesterified with acidified methanol. The fatty acid methyl esters were extracted with hexane. Fatty acids were detected by gas chromatography (GC).

Results

The major saturated fatty acids (SFAs) were myristic acid (C14:0), palmitic acid (C16:0) and stearic acid (C18:0) in both gonad and liver tissue. Oleic acid (C18:1 ω-9) and palmitoleic acid (C16:1 ω-7) were the prominent monounsaturated fatty acid (MUFA). The dominant polyunsaturated fatty acids (PUFAs) were linoleic acid (LA, C18:2 ω-6), arachidonic acid (AA, C20:4 ω-6), docosapentaenoic acid (C22:5 ω-3) and docoesahexaenoic acid (DHA, C22:6 ω-3). The ratio of ω-3/ω-6 ranged from 1.55 to 3.44 and 1.18 to 2.71 in the gonad and liver tissue, respectively.

Conclusion

The findings of this study will be useful for understanding the seasonal distribution of fatty acid composition in the liver and gonad of spiny eel.

Published: July 2017

Radiation has a potent to damage cells. Radiation may act directly or indirectly on deoxyribonucleic acid (DNA) that results in the degeneration of tissues and necrotic, and thereby it needs a potent radioprotector to prevent these damages. Vitamin E is natural product known as an antioxidant which has potential as radioprotector. This research aimed to determine the capability of vitamin E with emphasized on the searching for its optimal concentration as radioprotector of DNA damage. This study used blood samples of healthy person irradiated with gamma rays at a dose of 6 Gy as the lethal dose to lymphocytes. The cocentrations of vitamin E  from 0 to 0.8 mM was added into blood 15 minutes before irradiation. Isolation of lymphocytes was done using gradient centrifugation method. Evaluation on the capability of this compound in suppressing DNA damage was done by using alkaline Comet assay and data analysis was done using CaspLab program. The results show that addition of vitamin E could suppres these DNA damages and 0.8 mM of vitamin could reduce DNA damage up to 94.2%. We conclude that vitamin E effectively suppresed DNA damages induced by radiation. These results may benefit to enrich the radioprotectant information for radiotherapy patients.
Identification of Soybean Genotypes for Pod Shattering Resistance Associated with Agronomical and Morphological Characters
Authors: Krisnawati Ayda , Adie Mohamad Muchlish
Published: July 2017

A yield loss caused by pod shattering is one of the obstacles to the improvement of soybean productivity in tropical areas. The aim of this study was to identify the resistance of soybean genotypes to pod shattering as affected by agronomical and morphological characters. The field study was conducted in Malang, Indonesia, using 150 soybean genotypes. Data were collected on agronomical traits, the percentage of pod shattering, and pod morphological traits. Screening for shattering resistance was done as per oven dry method. Percentage of pod shattering was ranged from 0 % up to 100 % shattering with a mean of 58.11 %. Pod shattering was found to be negatively correlated with a number of pod per plant, the thickness of the pod, and Y/Z (seed weight and pod weight ratio). The screening obtained 66 very highly susceptible genotypes, 19 susceptible genotypes, 19 moderate genotypes, 38 resistant genotypes, and 8 very resistant genotypes. Two of eight very resistant genotypes (G511H/Anj//Anj///Anj////Anj-6-11 and G511H/Anj//Anj///Anj////Anj-5-4) have high yield, medium maturity day and large seed size. Those lines could be used as gene donor for soybean varietal improvement for shattering resistance, and recommended to propose as new improved soybean varieties resistant to pod shattering in Indonesia.

Published: July 2017

One of the main problems in the waste management in Indonesia is the treatment of leachate. This research is aimed to obtain information of histological alteration in gills and liver of C. carpio L. exposed to leachate. Measurements on the water quality parameters comprised water temperature, pH, and dissolved oxygen (DO). This research was conducted by exposing leachate to C. carpio for 96 hours. The concentration of leachate were 0 ppm, 80 ppm, and 100 ppm. Histological preparation were made on the gills and liver using 10% fixative Neutral Buffered Formalin and Ehrlich Hematoxylin-Eosin staining with qualitative observation descriptive analyses for discussion. The result showed that increasing water temperature is directly proportional to the leachate concentration in the aquaria, while the value of pH and DO inversely proportional to the leachate concentration. Damages on the gills with 80 ppm leachate concentrasion were identified as follows: fusion of secondary gill filaments and hyperplasia of epithelial cell, along with karyorrhexis and hydropic degeneration on the liver. Damages on the gills of fishes exposed to leachate with 100 ppm concentrasion were identified as follows: fusion of secondary gill filaments, hyperplasia of epithelial cell, congestion, and edema along with karyorrhexis, hydropic degeneration and melanomacrophage centre (MMC) found on the liver.

Este texto presenta datos de la educación física escolar colombiana en lo
relacionado con la tematización y la calidad en la educación. La orientación
metodológica incluye incursiones por referentes teóricos y el dialogo colaborativo establecido con dos investigadoras vinculadas a universidades colombianas. El objetivo de la investigación fue entender como la cultura es
tematizada en la producción de conocimiento de la educación física colombiana
dirigida para la escuela y si es posible hablar en calidad en la educación/
educación física en el país investigado. Los datos colectados nos llevan
a constatar que la educación física colombiana posee tendencia al deporte y
el tema de la cultura no se constituye como central en su campo epistemológico. En complemento, aunque sean percibidos avances en lo relacionado con la calidad de la educación física escolar colombiana, todavía se observa distanciamiento entre las conquistas obtenidas y el anhelo en términos de educación física humanística.
Megaeventos esportivos no Brasil: De expressão da política esportiva brasileira para a da concepção neodesenvolvimentista de planejamento urbano
Authors: Filho Lino
Published: July 2017

Buscamos neste Ensaio tecer considerações acerca dos megaeventos esportivos em solo brasileiro como expressão maior de uma determinada lógica de desenvolvimento urbano e menos de uma política esportiva propriamente dita, atentando para seus impactos na América do Sul. Neste particular, focaremos o paradoxo presente entorno do discurso oficial centrado no reconhecimento do Esporte como Direito Social versus uma prática comprometida com a concepção neodesenvolvimentista de planejamento urbano, ratificadora de sua apreensão como produto passível de ser mercantilizado com alto apelo no campo dos negócios.

Published: July 2017

BACKGROUND AND OBJECTIVES:

In 2000, the US Congress authorized the National Institutes of Health to conduct a prospective national longitudinal study of environmental influences on children’s health and development from birth through 21 years. Several recruitment methodologies were piloted to determine the optimal strategy for a main National Children’s Study.

METHODS:

After an initial pilot recruitment that used a household enumeration strategy performed poorly, the National Children’s Study Vanguard Study developed and evaluated the feasibility, acceptability, and cost of 4 alternate strategies to recruit a large prospective national probability sample of pregnant women and their newborn children. We compare household-based recruitment, provider-based recruitment, direct outreach, and provider-based sampling (PBS) strategies with respect to overall recruitment success, efficiency, cost, and fulfillment of scientific requirements.

RESULTS:

Although all 5 strategies achieved similar enrollment rates (63%–81%) among eligible women, PBS achieved the highest recruitment success as measured by the ratio of observed-to-expected newborn enrollees per year of 0.99, exceeding those of the other strategies (range: 0.35–0.48). Because PBS could reach the enrollment target through sampling of high volume obstetric provider offices and birth hospitals, it achieved the lowest ratio of women screened to women enrolled and was also the least costly strategy. With the exception of direct outreach, all strategies enrolled a cohort of women whose demographics were similar to county natality data.

CONCLUSIONS:

PBS demonstrated the optimal combination of recruitment success, efficiency, cost, and population representativeness and serves as a model for the assembly of future prospective probability-based birth cohorts.

The purpose of the present study was to quantify the presence of chemokine CCL5 (RANTES) in gingival crevicular fluid (LCG) in patients with chronic periodontitis (PC) and / or type 2 diabetes mellitus (DM2). A comparative cross-sectional study was conducted in 40 patients. LCG was taken from periodontal pockets and gingival grooves from 4 patient groups (10 per study group); patients who received periodontal, antibiotic and anti-inflammatory treatment 6 months prior to the study or who had systemic disease other than DM2 were excluded. Concentrations of CCL5 were determined by LUMINEX® assays. Descriptive statistics, one-way ANOVA, Student's T, and Pearson's correlation were performed. The quantification of CCL5 was higher in the patients who presented both diseases, followed by the group with only PC, healthy and the group with only DM2. No significant difference was found between groups and there was no correlation between quantifications and glycemic indicators. Although the differences were not significant, the group of patients with both diseases had the highest CCL5 quantification. The expression of CCL5 in LGC should be considered as a potential inducer of periodontal destruction, its determination could be useful for monitoring the health/disease of periodontal tissues.
Preventive Analgesia: An Evidence-Based Alternative for Dentistry
Authors: Chavarría-Bolaños DDS, MSc, PhD Daniel , Esparza-Villalpando DDS, MSc Vicente
Published: July 2017

The effective management of pain in dentistry increases the patient satisfaction, improves the treatment outcome and reduces the cost of care. To achieve this goal, different strategies are available for the administration of analgesics, such as preventive analgesia. The aim of this approach is to minimize sensitization induced by noxious perioperatory stimuli (both pre, intra and postoperatory). Available research support the favorable effect of preventive analgesia, although it also recognizes an important lack of high quality evidence to confirm its advantages. This new perspective article summarizes the preventive analgesia protocol, and its potential use in dentistry.

Published: July 2017

The purpose of this study was to determine the effect of different surface treatments on the bond strength between resin cements and quartz fiber-reinforced resin posts. Materials and methods: Sixty quartz fiber-reinforced resin posts (DT Light-Post™, Bisco™) were randomly divided into 12 experimental groups (n=5), according to the resin cement used (Biscem™ or Duolink™) and the surface treatment: Alcohol (control group), silanized, primer, sandblasted, sandblasted + silanized or sandblasted + primer. Cylindrical resin specimens were obtained using nanohybrid resin. The posts were cemented to the resin discs and push-out tests were conducted. Data were analyzed with ANOVA and T test for averages comparison and the Tukey HSD test with a 95% level of significance. Results: Biscem™ cement generally showed higher bond strength when compared to Duolink™ Significant differences were found between the control group and the sandblasted + silane and sandblasted + primer groups when using Duolink™cement. With Biscem™ cement, no differences between groups or with the control group were found.. Conclusion: Surface treatments on quartz fiber-reinforced resin poles seem to have no significant effect on the bond strength to resin cements, except when using Duolink™ cement with sandblasted posts and using silane or primer.
Konzert als Groteske — Anmerkungen zum ersten Satz des Violinkonzerts
Authors: Helbing Volker
Published: July 2017

The grotesque and the theatrical, as essential facets of Ligeti’s oeuvre, become more evident in his Violin Concerto than in most of his works from the 1980s. The analysis shows how these facets find expression on different levels of the composition — from the harmonic and rhythmic pre-settings over the compositional detail to the individual interpretation of the Violin Concerto as a genre and the formal dramaturgy.
Verwendung, Verleugnung, Wiederentdeckung – Ligeti und ethnische Musiken
Authors: Kerékfy Márton
Published: July 2017

Regarding György Ligeti’s relation to ethnic music, his oeuvre can be divided into three periods. Until 1956 he used East European folk music in the manner of Hungarian composition of the 1940s and 1950s, but upon leaving Hungary he apparently rejected folkloristic inspiration. In his late period from 1978 on, however, ethnic musics became again central to his creative work, albeit in a basically different way than in his youth. This article provides an overview of Ligeti’s early folkloristic pieces and a brief characterization of his use of elements of Eastern European folklore in Le Grand Macabre, Hungarian Rock, Passacaglia ungherese and the Horn Trio. Finally, it traces back Ligeti’s “lamento melody,” that appears for the first time in the last movement of the Horn Trio, to certain types of the Hungarian folk lament. Ligeti’s references to folklore do not mean an idealization of his past, but are rather signs of an ambivalent attitude toward his own roots, in which nostalgic longing, ironic distancing, and desperate mourning are equally present.
Allusion — Einschluss — Gekerbter Raum. Traditionelle Residuen bei Ligeti
Authors: Jeßulat Ariane
Published: July 2017

Tonal residua and other remnants of older musical styles and idioms seem to be inevitably bound to Ligeti’s musical language. The numerous ways of integrating the stylistic heterogeneity in his works are extremely individual and may be seen as part of each work’s specific narrative. In his early essay about musical form, Ligeti interprets Adorno’s idea of material as a parameter of form either as congealed time or as traces of musical memory. This article aims to show the different levels and qualities of musical thought Ligeti deals with by analyzing the different layers of traditional strata in his music.
