Authors: Kunz Seraina M. , Holzmann David , Waser Yves , Meerwein Christian , Deggeller Marcel , Soyka Michael B.
Published: July 2019

Background

Epistaxis is the most common otorhinolaryngologic emergency around the world. A broad variety of treatment options is available; ranging from conservative measures such as cauterization and nasal packings to surgery. For posterior epistaxis, nasal packings are usually the preferred initial treatment method. There are 2 different models of the widely used Rapid Rhino™ packing available at our department; the 7.5 cm, single-lumen, and the 9 cm, double-lumen variant with 2 separately inflatable balloons. Identifying whether one packing is superior to the other will help with the choice of the best possible treatment.

Objective

The goal of this study was to determine whether the new, double-lumen model had advantages compared to its shorter counterpart.

Methods

All patients treated with Rapid Rhino™ packings for spontaneous epistaxis between December 2005 and October 2017 were analyzed for various parameters such as recurrence rates, hospitalization rate, and duration of in-patient stay. The groups were divided by model and whether patients were treated before or after the introduction of the double-lumen version (December 2010).

Results

A total of 865 cases of patients treated with Rapid Rhino™ packs were analyzed. Before December 2010, 210 of 372 cases (56%) were hospitalized, whereas afterwards it was only 48% (235/493; P = .01). The duration of the in-patient stay decreased from 3.7 to 3.1 days ( P < .01). There was no difference in recurrence rates.

Conclusion

The introduction of the double-lumen, 9 cm Rapid Rhino™ packing has led to a decrease of in-patient time and to less hospitalizations. Therefore, it should be preferred to the shorter, single-lumen model in the treatment of posterior epistaxis.

Published: July 2019

Objectives:

The aim of this study is to empirically examine a full pathway model of health literacy, and health and well-being outcomes among patients with type 2 diabetes.

Methods:

A three-wave longitudinal survey was administered to 148 patients with diabetes. Covariance structure analysis was conducted to create a path diagram, with health literacy and burden of medical expenses included as independent variables and with psychosocial factors, behaviors, and health and well-being outcomes included as dependent variables.

Results:

The model fit indices showed a comparative fit index of 0.985 at baseline, 0.959 after 3 months, and 0.948 after 6 months, with a root mean square error of approximation of 0.040 at baseline, 0.079 after 3 months, and 0.085 after 6 months. There were 14 significant paths across the three time points between health literacy and understanding of diabetes care, self-efficacy, communication with doctors, and medication adherence.

Conclusion:

The model fitness index showed an adequate result. Health literacy was significantly positively associated with understanding of diabetes care, self-efficacy, communication with doctors, and medication adherence. Health literacy had a direct positive influence on medication adherence and possibly an indirect positive influence on exercise/diet via self-efficacy. The results were generally consistent across the three time points, suggesting good reliability of the models. Improving health literacy may lead to better self-management of diabetes and favorable health outcomes.
The U.S. Presidential Election 2012/2016 and Investors’ Sentiment: The Case of CBOE Market Volatility Index
Authors: Shaikh Imlak
Published: July 2019

Given that political events have substantial effect on new economic policies and economic performance of the country, this article aims to examine the behavior of the investors’ sentiment in terms of implied volatility index trailed by the U.S. presidential elections. The study empirically tests whether the presidential elections in 2012/2016 do contain the important market inclusive information to explain the expected stock market volatility. The findings indicate that investors’ concern was distracted around the presidential elections window, albeit the market performed identically in both the presidential election years. The significant fall in the implied volatility level (post-election period) is the calm before the storm, just wait and watch. The positive estimate uncovers the fact that investor worries were higher before the election day. In particular, the significant estimate of the presidential election debate shows that investors do regard the minutes of the presidential election debates in their portfolio selection. At the two elections era, on the candidacy of both the parties, the empirical result speaks marginally contrasting outcomes and falsifies the presidential election cycle hypothesis of past 29 U.S. election years. Empirical estimates conclude that the presidential elections in 2012/2016 have a strong, significant relationship with investor’s sentiment and stock market performance.

Published: July 2019

The purpose of the study was to analyze the factors affecting the acceptance and adoption of e-Health applications among African expats in China from the patient’s perspective. This research used extended technology acceptance model (TAM) with the addition of privacy and trust. The survey method with the structured questionnaire was used to collect data from more than 300 African expats in three Tier 1 cities of China. Hypotheses were tested using partial least squares (PLS) method, a structural equation modeling (SEM) based statistical technique. The results show that perceived usefulness, perceived ease of use (PEU), and privacy have significant effects on intention to use (INT) e-Health technologies. Moreover, PEU endorses positive impact on perceived usefulness. The results also revealed that gender was partially associated with the acceptance and use of e-Health technologies. However, surprisingly, trust had an insignificant effect on INT of e-Health. The results of the current research provide the foundation for the development of policies and strategies for the enhancement of e-Health services to African expats in China. Moreover, the acceptance model of current study can be modified easily because of its generic approach for the investigation of adoption of e-Health services among other developing countries’ expats in China.

Does Combining a Suprascapular Nerve Block With an Intra-articular Corticosteroid Injection Have an Additive Effect in the Treatment of Adhesive Capsulitis? A Comparison of Functional Outcomes After Short-term and Minimum 1-Year Follow-up
Authors: Jung Tae Wan , Lee Seung Yeop , Min Seul Ki , Lee Sang Min , Yoo Jae Chul
Published: July 2019

Background:

No therapeutic intervention is universally accepted as the most effective treatment for adhesive capsulitis. An intra-articular corticosteroid injection (IAI) with a suprascapular nerve block (SSNB), a common treatment for this disease, is a safe and effective method for the resolution of pain and restoration of shoulder range of motion (ROM).

Purpose:

To compare the efficacy of combined SSNB and IAI with that of IAI alone in the treatment of adhesive capsulitis.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

We performed a retrospective review of 102 patients with adhesive capsulitis who were treated at an outpatient clinic from July 2016 to January 2017. A combined SSNB with IAI was performed in 48 patients (SSNB + IAI group), and an IAI alone was performed in 54 patients (IAI group). Patients were assessed before the intervention and at 2 weeks and 2 months after the intervention. ROM and pain and function visual analog scales (PVAS and FVAS, respectively), the American Shoulder and Elbow Surgeons (ASES) score, the Korean Shoulder Scoring System (KSS), the Constant score, the Simple Shoulder Test (SST), and the Shoulder Pain and Disability Index (SPADI) were used for clinical assessments. PVAS, FVAS, and ASES scores at a minimum of 1 year after the intervention were assessed for 82 patients.

Results:

At the 2-month assessment, all parameters significantly improved in both the SSNB + IAI and IAI groups ( P < .05), however, improvements in forward flexion (FF) and abduction (ABD) between the 2-week and 2-month assessments were better in the SSNB + IAI group. At the 2-month assessment, improvements in the FVAS, ASES, SST, and SPADI scores and FF and ABD values were statistically significantly greater in the SSNB + IAI group compared with the IAI group. Improvements in FVAS and ASES scores were significantly greater in the SSNB + IAI group at a minimum of 1 year.

Conclusion:

Both a combined SSNB and IAI and an IAI alone significantly improved pain and functional outcomes in patients with adhesive capsulitis. The use of an SSNB with an IAI further increased treatment efficacy, as per the FVAS, ASES, SST, and SPADI scores and FF and ABD values. Patients who underwent SSNB combined with an IAI showed better improvements in the FVAS and ASES scores compared with IAI alone at a minimum of 1 year after the intervention. Therefore, an SSNB combined with an IAI may be a good treatment choice for adhesive capsulitis.
Shape memory polyurethane/graphene nanocomposites: Structures, properties, and applications
Authors: Kausar Ayesha
Published: July 2019

This review presents an overview of the versatile shape memory polyurethane/graphene nanocomposites. Shape memory polyurethanes can recover their original shape from an intermediate shape when triggered by an external stimulus, such as heat, electrical voltage, light, pH change, or water absorption. Shape memory polymers have a successful history in commercial use. The applications for shape memory polymers are highly varied across numerous industries ranging from aircraft structure to biomedical implants. Three different groups of stimuli-responsive shape memory polyurethane/graphene nanocomposites, thermoresponsive, resistive heating actuated, and photon absorption actuated, will be discussed in this review. The applications of shape memory polyurethane/graphene nanocomposite as actuators are also discussed. This article will be pioneering in widespread impression on the state-of-the-art knowledge in shape memory polyurethane/graphene nanocomposites. It does not intend to be an extensive summary, but instead is a guide for scientists looking to apply these uniquely functional materials for advance high-performance applications. Future research may reveal shape memory applications for polyurethane/graphene nanocomposites in electronics, aerospace, and biomedical industries.
Evaluation of the hypersingular boundary integral equation for acoustic wave-propagation simulations
Authors: Wei Jia , Fu Li-Yun
Published: July 2019

We have developed a hypersingular boundary integral equation (BIE) approach to simulate wave scattering by inclusions such as karstic cavities and gypsum salts. The solution of conventional BIEs for exterior boundary value problems is of nonuniqueness and numerical instability at characteristic wavenumbers (corresponding to fictitious resonant frequencies). With the hypersingular boundary integral operator, we can handle this problem, but with the difficult-to-calculate hypersingular kernels. Our method to evaluate the singular part in the operator is more efficient than other singularity-elimination techniques. Numerical examples validate the method by comparing with the analytical solution.

Published: July 2019

PURPOSE

There is limited access to quality palliative care (PC) for patients with advanced cancer in sub-Saharan Africa. Our aim was to describe the development of the Project Extension for Community Healthcare Outcomes-Palliative Care in Africa (ECHO-PACA) program and describe a preliminary evaluation of attitudes and knowledge of participants regarding the ability of the program to deliver quality PC.

METHODS

An interdisciplinary team at the MD Anderson Cancer Center, guided by experts in PC in sub-Saharan Africa, adapted a standardized curriculum based on PC needs in the region. Participants were then recruited, and monthly telementoring sessions were held for 16 months. The monthly telementoring sessions consisted of case presentations, discussions, and didactic lectures. Program participants came from 14 clinics and teaching hospitals in Ghana, Kenya, Nigeria, South Africa, and Zambia. Participants were surveyed at the beginning, midpoint, and end of the 16-month program to evaluate changes in attitudes and knowledge of PC.

RESULTS

The median number of participants per session was 30. Thirty-three (83%) of 40 initial participants completed the feedback survey. Health care providers’ self-reported confidence in providing PC increased with participation in the Project ECHO-PACA clinic. There was significant improvement in the participants’ attitudes and knowledge, especially in titrating opioids for pain control ( P = .042), appropriate use of non-opioid analgesics ( P = .012), and identifying and addressing communication issues related to end-of-life care ( P = .014).

CONCLUSION

Project ECHO-PACA was a successful approach for disseminating knowledge about PC. The participants were adherent to ECHO PACA clinics and the completion of feedback surveys. Future studies should evaluate the impact of Project ECHO-PACA on changes in provider practice as well as patient outcomes.
Sex differences in gene expression patterns associated with the APOE4 allele
Authors: Hsu Michelle , Dedhia Mehek , Crusio Wim E , Delprato Anna
Published: July 2019

Background:TheAPOEgene encodes apolipoprotein ε (ApoE), a protein that associates with lipids to form lipoproteins that package and traffic cholesterol and lipids through the bloodstream. There are at least three different alleles of theAPOEgene:APOE2,APOE3, andAPOE4. TheAPOE4allele increases an individual's risk for developing late-onset Alzheimer disease (AD) in a dose-dependent manner. Sex differences have been reported for AD susceptibility, age of onset, and symptom progression, with females being more affected than males.

Methods:In this study, we use a systems biology approach to examine gene expression patterns in the brains of aged female and male individuals who are positive for theAPOE4allele in order to identify possible sex-related differences that may be relevant to AD.

Results:Based on correlation analysis, we identified a large number of genes with an expression pattern similar to that ofAPOEinAPOE4-positive individuals. The number of these genes was much higher inAPOE4-positive females than inAPOE4-positive males, who in turn had more of such genes thanAPOE4-negative control groups. Our findings also indicate a significant sex* genotype interaction for the CNTNAP2 gene, a member of the neurexin family and a significant interaction for brain area*sex* genotype for PSEN2, a risk factor gene for AD. 

Conclusions:Profiling of these genes using Gene Ontology (GO) term classification, pathway enrichment, and differential expression analysis supports the idea of a transcriptional role ofAPOEwith respect to sex differences and AD.
Myopia Outcome Study of Atropine in Children (MOSAIC): an investigator-led, double-masked, placebo-controlled, randomised clinical trial protocol

Published: July 2019

Background: The Myopia Outcome Study of Atropine in Children (MOSAIC) aims to explore the efficacy, safety, acceptability and mechanisms of action of 0.01% unpreserved atropine for myopia control in a European population.

Methods: MOSAIC is an investigator-led, double-masked, placebo-controlled, randomised clinical trial (RCT) investigating the efficacy, safety and mechanisms of action of 0.01% atropine for managing progression of myopia. During Phase 1 of the trial, 250 children aged 6-16 years with progressive myopia instil eye drops once nightly in both eyes from randomisation to month 24. No treatment is given during Phase 2 from month 24 to 36 (washout period) for those participants initially randomised to the intervention arm (n=167), during which any potential rebound effects on cessation of treatment will be monitored. All participants initially assigned to the placebo (n=83) crossover to the intervention arm of the study for Phase 2, and from month 24 to 36, instil 0.01% atropine eye drops in both eyes once nightly. Further treatment and monitoring beyond 36 months is planned (Phase 3) and will be designed dependent on the outcomes of Phase 1.

Results: The primary outcome measure is cycloplegic spherical equivalent refractive error progression at 24 months. Secondary outcome measures include axial length change as well as the rebound, safety and acceptability profile of 0.01% atropine. Additional analyses will include the mechanisms of action of 0.01% atropine for myopia control.

Conclusions: The generalisability of results from previous clinical trials investigating atropine for myopia control is limited by the predominantly Asian ethnicity of previous study populations. MOSAIC is the first RCT to explore the efficacy, safety and mechanisms of action of unpreserved 0.01% atropine in a predominantly White population.

Towards a heart and soul for co-creative research practice: a systemic approach
Authors: Nicholas Graeme , Foote Jeff , Kainz Kirsten , Midgley Gerald , Prager Katrin , Zurbriggen Cristina
Published: July 2019

The language of co-creation has become popular with policy makers, researchers and consultants wanting to support evidence-based change. However, there is little agreement about what features a research or consultancy project must have for peers to recognise the project as co-creative, and therefore for it to contribute to the growing body of practice and theory under that heading. This means that scholars and practitioners do not have a shared basis for critical reflection, improving practice and debating ethics, legitimacy and quality. While seeking to avoid any premature defining of orthodoxy, this article offers a framework to support researchers and practitioners in discussing the boundaries and the features that are beginning to characterise a particular discourse, such as the one that is unfolding around the concept of co-creation. The paper is the outcome of an online and face-to-face dialogue among an international group of scholars. The dialogue draws on Critical Systems Heuristics’ (Ulrich, 1994) questions concerning motivation (revealing assumptions about its purpose and value), power (interrogating assumptions about who has control and is therefore able to define success), knowledge (surfacing assumptions about experience and expertise) and legitimacy (disclosing moral assumptions). The paper ends by suggesting important areas for further exploration to contribute to the emerging discourse of co-creation in ways that support critical reflection, improved practice, and provide a basis for debating ethics and quality.

Published: July 2019

The total metal concentrations (Cd, Cu, Pb, Zn, Mn, Ni, Cr, and Fe) in the mesozooplankton (200 μm–2 mm) were studied for a year in a human-impacted estuary strongly affected by urban and industrial discharges located in the South Atlantic. Over the last 25 years, this estuary
has been the site of significant anthropogenic impacts including industrial activities, maritime traffic, and regular dredging. A quantitative and qualitative analysis was also carried out to identify the mesozooplanktonic community that was sampled for metal determinations. The mesozooplankton
had high concentrations of toxic metals such as Cd, Pb, Cr, and Ni, which may indicate that these organisms are strong accumulators of these metals. Also, the analyzed metals had a wide temporal variation, the highest levels being in autumn and spring. The ranges were as follows: cadmium (Cd):
0.3–3.8; copper (Cu): 35.3–226.6; chromium (Cr): 1.4–57.9; iron (Fe): 1060–57370; manganese (Mn): 18–1102; nickel (Ni): 2.8–57.3; lead (Pb): 2.4–66.7; zinc (Zn): 97.6–1872.2 (μg g –1dry weight). Total zooplankton abundance also showed
a significant temporal variation and the most important taxa were the copepods Acartia tonsa, Eurytemora americana, the barnacle Balanus spp. (in the nauplius larval stage), and the crab Cyrtograpsus altimanus (in the zoea larval stage).
 In zooplankton, all
the metals were detected throughout the whole sampling year and at all sampling sites, which suggests the presence of continuous or quasi-continuous sources of these contaminants. Thus, the most abundant zooplankton species could be considered as potential biomonitors for trace metals in heavily
impacted marine environments like estuaries.
Fashion archives, museums and collections in the age of the digital
Authors: Pecorari Marco
Published: July 2019

Currently there is a trend for the digital in archives, collections and museums of fashion. Not only are museums digitalizing and giving free online access to their collections, but new types of digital fashion archives and collections are emerging thanks to the advent of the Internet and the proliferation of social media. This article explores this shift, functioning as both an introduction to this thematic issue and as a mapping of the different transformations lived by archives, museums and collections in the age of the digital. How has the digital effected a different understanding of fashion in museums, archives and collections? What types of challenges is the digital bringing to museum practitioners and scholars? In the following sections, my aim is to emphasize some areas of transformation, highlighting four contested fields: (1) the dichotomies between archives/museums and the digital in relation to issues of access and fashion heritage; (2) the shift from material to digital archives and the effects of practices of digitalization of fashion archives; (3) the emergence of new ephemeralities and the utopic practices of conserving online fashion; and (4) the expansion of the understanding of fashion archives and the consequent effects on users’ agency and research practices. Drawing on digital studies, archive theory, museum studies, heritage studies and fashion studies, I reflect on these shifts, contextualizing the articles published in this thematic issue and revisiting the scope of some of the projects I developed in collaboration with the EU-funded project Europeana Fashion.

Zone of Inhibition: Relating to the Single Cell through Speculative Performance Practice
Authors: Mackenzie Louise
Published: July 2019

This article presents extracts from a short film - a speculative vital materialist tale that reaches beyond a human perception of time, to document a conversation between a past-present-future sentient community-being of cells and their kin, present day humans who are always already
symbiotically and parasitically involved in their generation. The conversation took place during a participatory performance workshop held at ASCUS Lab in Edinburgh, 2017, where participants genetically modified E. coli bacteria to hold a thought (DNA with no known biological meaning, only
cultural meaning) within their bodies, and were then invited to enter into a speculative dialogue with their distant cellular kin.

Este trabalho tem como objetivo analisar as influências dos Planos Viários Nacionais de 1874 a 1951 na organização geoestratégica da mesorregião do Triângulo Mineiro/Alto Paranaíba, Oeste do Estado de Minas Gerais, uma vez que estes foram fundamentais para a instalação de uma dinâmica territorial com consequências diretas sobre o interior do país, os quais inseriram essa mesorregião em uma condição estratégica de integração. A atenção principal do trabalho centra-se sobre os planos projetados e/ou implementados durante a Primeira República e a Era Vargas, tendo-se como pressuposto que os mesmos se constituíram em aportes fundamentais para o desenho das redes viárias modernas construídas após a década de 1950. Para tanto, o artigo estrutura-se a partir do levantamento e análise dos planos viários do período em evidência. Paralelamente à compreensão do contexto que deu origem a esses planos, analisa-se as estratégias locais adotadas no sentido de criar para a região do Triângulo Mineiro uma dinâmica específica centrada na logística de transportes. A compreensão do processo de instalação dos sistemas viários na região é um ponto chave para compreender o papel da dinâmica instalada no Triângulo Mineiro dentro do projeto do Estado Nacional para a articulação e modernização do território brasileiro.

Authors: Diniz Marco Túlio Mendonça , Vasconcelos Fábio Perdigão
Published: July 2019

Existem dados da produção de sal marinho a partir do ano de 1938, neste trabalho estes dados foram analisados ano a ano, com destaque para períodos de crescimento, decréscimo e estagnação. Estes períodos foram correlacionados com transformações econômicas e nos espaços de produção da atividade salineira. As transformações espaciais foram analisadas dos pontos de vista social e natural. O método estatístico utilizado para correlacionar as variáveis pluviometria, PIB do Brasil e produção nacional de sal marinho foi o Coeficiente de Correlação de Pearson. A atividade salineira tem seu crescimento relacionado com o crescimento econômico do país e com a modernização pela qual o setor passou entre os anos 1960 e 1970 quando o Rio Grande do Norte se consolidou como maior produtor nacional. Existe forte influencia do meio natural com o desenvolvimento da atividade salineira, que é concentrada, principalmente, em determinada porção do Nordeste Setentrional, nessa região a atividade é influenciada pela variação interanual do regime de chuvas.

Published: July 2019

O uso racional dos recursos hídricos em determinado recorte geográfico é fundamental para manutenção das atividades socioeconômicas, da garantia energética e alimentar para as formas de vida da biosfera. A qualidade da água, que é resultado da interação da mesma com as características geossistêmicas de uma bacia hidrográfica, pode ser estimada e consequentemente caracterizada para definir o seu valor monetário para os diversos tipos de atividades econômicas. A questão central do trabalho é construída para evidenciar que, no Brasil, é possível pensar numa abordagem integrada que permite valorar a água em função de sua qualidade, envolvendo coeficientes quantificados originados dos sistemas naturais e antrópicos da bacia hidrográfica. Essa é uma afirmativa que exige um olhar geográfico, pois tal ciência possibilita conectar análises multidisciplinares referentes a água. As nuances metodológicas subsidiam a definição de valores ajustados em função de tais características, sendo uma metodologia passível de implementação por parte do Sistema Nacional de Recursos Hídricos.

Published: July 2019

O estudo apresenta uma análise da paisagem na bacia hidrográfica do Rio Verde, território indígena Paresi em Tangará da Serra - Mato Grosso.  Pautada no método geossistêmico somado ao viés crítico da geografia. Envolveu estudos sobre concepções diferenciadas na relação sociedade-natureza entre os Paresi-Haliti e os fazendeiros do entorno. Assinalada pela resistência dos indígenas frente ao processo de homogeneização da paisagem. O resultado cartográfico do uso e ocupação do solo nos últimos trinta anos revelou uma paisagem muito alterada no entorno da terra indígena, marcada pelas geometrias das plantações de commodities de grãos. Já no território indígena a vegetação natural foi mantida praticamente conservada. Entrevistas com os fazendeiros e indígenas apontaram incompatibilidades nos usos múltiplos do rio. Rituais tradicionais foram comprometidos, pois muitos locais sagrados ficaram situados fora do território delimitado, em áreas particulares. Houve também uma diminuição dos animais de caça pela perda de habitat. O território indígena Paresi representa, juntamente com outros territórios indígenas, a riqueza da heterogeneidade cultural e também acabaram assumindo um importante papel na preservação dos biomas no estado.

Tensiones creativas entre emprender y asociarse: recorridos teóricos sobre la autogestión y el asociativismo en América Latina
Authors: Azerrad María Rut , Rossler Germán
Published: July 2019

Los antecedentes de investigaciones sobre las iniciativas económicas asociativas de los emprendedores del Centro de Emprendedores de la Economía Social (CEES) de la ciudad de Santa Fe, generaron la necesidad de focalizar el análisis en los conceptos de autogestión y asociativismo. Se explorarán las teorías que enmarcan la hipótesis emergente de estas investigaciones previas sobre las tensiones entre: emprender y asociarse, dónde la capacidad emprendedora no acompaña la voluntad asociativa y simultáneamente se confunde autogestión con individualismo A partir de aportes de autores latinoamericanos del campo de la Economía Social y Solidaria (ESyS) se expone la complejidad teórica y la densidad propositiva que implica la noción de autogestión. Posteriormente se revisan las conceptualizaciones sobre el asociativismo, para identificar los principales elementos de esta noción. Se diferencian distintos tipos y estilos de cooperación, lo que permite abordar las posibles motivaciones de los emprendedores sociales para desarrollar estos tipos de prácticas. Finalmente se considera al asociativismo como una estrategia fundamental en la construcción de su sostenibilidad a partir de un repaso sobre distintas perspectivas de este concepto. Estos recorridos buscan generar algunos insumos teóricos fundamentales al momento de indagar sobre los sentidos de autogestión y asociativismo que construyen los emprendedores del Centro de Emprendedores de la Economía Social (CEES) de la Ciudad de Santa Fe.

Recent studies on musical signification have been characterized by an apparently insurmountable gap between disciplines that focus on the musical text as sound (music theory, musicology), those that focus on the hearing subject (cognitive sciences, psychology of music), and those that focus on social discourses about music (ethnomusicology, anthropology, sociology). This article argues that the most recent theoretical advances in music semiotics provide means to overcome this gap. After a brief examination of some key concepts in music semiotics, the author identifies three approaches to this problem: the semiotic-hermeneutic approach, the cognitive-embodied approach, and the social-political approach. This classification allows him to introduce a brief methodological proposal for the study of musical signification from different academic perspectives.

Vladimír Úlehla (1888-1947) uses his expertise in the biological sciences to perform an in-depth and ecologically situated study of folk songs from his native Czechoslovakia. His posthumous magnum opus Živá Píseň (Living Song, 1949) chronicled the musical traditions of Strážnice, a small town at the western hem of the Carpathian Mountains at the Moravian-Slovakian border. Informed by four decades of ethnographic inquiry, transcription, and several music-analytical methods, in Chapter VI Úlehla considers the songs from Strážnice as living organisms, links them to their ecological environs, and isolates musical characteristics that he believes correspond to stages of their evolution. He discusses modulation, vocal style, ornamentation, melodic and poetic structure, and identifies a diverse array of musical modes—evidence that he uses to refute the prevailing assumption of the day that folk music was derivative of art music.

The present study focuses on foreign language enjoyment (FLE) and foreign language classroom anxiety (FLCA) of 592 learners of Turkish as a foreign language (FL) in Kazakhstan. Mean levels of FLE and FLCA were found to be similar to previous studies in different settings with different target languages. In contrast with previous literature, a weak positive correlation was found between FLE and FLCA and the gender effect went in the opposite direction, with male participants reporting more FLCA than female participants. Multiple regression analyses revealed that FLE and FLCA were more strongly predicted by learners’ attitude toward Turkish and teacher-related variables than by learner-internal variables, confirming previous research outside Kazakhstan. Attitude toward the FL, teacher’s friendliness, strictness and frequency of use of the FL, attitude toward the teacher, participant’s age and FL exam result explained a total of 25% of variance in FLE. Differing slightly from previous studies, FLCA was found to be only weakly predicted (6% of variance) by some learner-internal variables (FL exam result, attitude toward the FL) as well as teacher-centred variables (friendliness, strictness). The findings suggest that variation in FLE and FLCA among Kazakh learners of Turkish is quite similar to that established in other contexts.

Published: July 2019

The study has outlined various photonic crystal fibers (PCFs) configurations for the key solution to the optimization of data rates transmission. The proposed fibers that are namely octagonal photonic crystal fiber (OPCF), hexagonal photonic crystal fiber (HPCF), and elliptical photonic crystal fiber (E-PCF) are used in the system. The dispersion parameter coefficient, pulse broadening variations, and data rates transmission are examined for proposed fibers under the same fiber lengths and number of quantization level with using pulse code modulation (PCM). The system performance is enhanced with OPCF with reducing dispersion factor, pulse broadening effects and consequently increasing data rates transmission.

Nano-TiO2 film attracts great attention by its excellent photocatalytic activity performance. The application of nano-TiO2 film based on fabric substrate in indoor household textiles is helpful for purifying air and degrading formaldehyde content in indoor environments. In this paper, the nano-TiO2 films were prepared on fiberglass substrate by the sol-gel method, and the appearance of fabrics coated with nano-TiO2 at conditions of both without calcination (room temperature) and high temperature calcination (300∘C, 350∘C, 400∘C) was studied. In addition, X-ray diffraction technology was applied to analyze the crystallization of TiO2 film, with further discussion of the photocatalytic performance of degrading helianthin under UV irradiation.The results show that with increase of calcination temperature, the color of the fabric gets darker and darker until the powder peeling and dyeing reaches the maximum degree, the fabric becomes fragile, the anatase crystal form of TiO2 film tends to be complete, and the photocatalytic performance is improved. It is feasible to apply TiO2 film on the surface of fabrics in the design of indoor household textiles.
Forschung und Entwicklung von Unternehmen in langfristiger Perspektive: Starkes Wachstum, alte Akteure?
Authors: Dachs Bernhard , Drach Andreas
Published: July 2019

Wie stark bestimmt das Wachstum junger, forschungsintensiver Unternehmen das technologische Leistungsvermögen von Ländern? Bernhard Dachs und Andreas Drach untersuchen dies anhand der Entwicklung in Österreich. Das Land ist für eine solche Analyse besonders geeignet, denn die Ausgaben für Forschung und Entwicklung (F&E) österreichischer Unternehmen haben sich seit 2002 mehr als verdoppelt. Die Analyse auf Basis von Firmendaten zeigt, dass dieser Anstieg vor allem von großen, etablierten und nur zu einem geringen Teil neuen Unternehmen ausging. 62 Prozent der F&E-Ausgaben des Jahres 2013 stammen von Unternehmen, die bereits 2002 F&E betrieben. Die Wahrscheinlich­keit, dass kleine F&E-Betreiber in die Gruppe der großen, forschungsintensiven Akteure aufsteigen, ist sehr gering. Diese Beobachtung weist auf institutionelle Hemmnisse im Innovationssystem hin. Eine Analyse der Gründe ist notwendig, um dem österreichischen Innovationssystem – aber auch denen anderer EU-Länder – mehr Dynamik zu verleihen.
Determinism versus randomness in plankton dynamics: The analysis of noisy time series based on the recurrence plots

Published: July 2019

The quantitative analysis of recurrence plots while applied to mathematical models was shown to be an effective tool in recognizing a frontier between deterministic chaos and random processes. In nature, however, unlike mathematical models, deterministic processes are closely intertwined with random influences. As a result, the non-structural distributions of points on the recurrence plots, which are typical of random processes, are inevitably superimposed on the aperiodic structures characteristic of chaos. Taking into account that the stochastic impacts are an inherent feature of the dynamics of populations in the wild, we present here the results of the analysis of recurrence plots in order to reveal the extent to which irregular phytoplankton oscillations in the Naroch Lakes, Belarus, are susceptible to stochastic impacts. We demonstrate that numerical assessments of the horizon of predictability Tpr of the dynamics under study and the average number Pd of the points that belong to the diagonal segments on the recurrence plots can furnish insights into the extent to which the dynamics of both model and phytoplankton populations are affected by random components. Specifically, a comparative analysis of the values of Tpr and Pd for the time series of phytoplankton and the time series of random processes allows us to conclude that random components of the phytoplankton dynamics in the Naroch Lakes do not prevent recognition of chaotic nature of these dynamics.

Introduction

Parathyroid carcinoma represents a rare cause of primary hyperparathyroidism. Distinguishing carcinoma from the benign tumors underlying primary hyperparathyroidism remains challenging. The diagnostic criteria for parathyroid carcinoma are local and/or metastatic spreading. Atypical parathyroid adenomas share other histological features with carcinomas but lack invasive growth. Somatostatin receptors are commonly expressed in different neuroendocrine tumors, but whether this also holds for parathyroid tumors remains unknown.

Aim

Our aim is to examine the immunohistochemical expression of somatostatin receptor 1–5 in parathyroid typical adenomas, atypical adenomas and carcinomas.

Methods

We used a tissue microarray construct from a nationwide cohort of parathyroid carcinomas (n = 32), age- and gender-matched typical parathyroid adenomas (n = 72) and atypical parathyroid adenomas (n = 27) for immunohistochemistry of somatostatin receptor subtypes 1–5. We separately assessed cytoplasmic, membrane and nuclear expression and also investigated the associations with histological, biochemical and clinical characteristics.

Results

All parathyroid tumor subgroups expressed somatostatin receptors, although membrane expression appeared negligible. Except for somatostatin receptor 1, expression patterns differed between the three tumor types. Adenomas exhibited the weakest and carcinomas the strongest expression of somatostatin receptor 2, 3, 4 and 5. We observed the largest difference for cytoplasmic somatostatin receptor 5 expression.

Conclusions

Parathyroid adenomas, atypical adenomas and carcinomas all express somatostatin receptor subtypes 1–5. Somatostatin receptor 5 may serve as a potential tumor marker for malignancy. Studies exploring the role of somatostatin receptor imaging and receptor-specific therapies in patients with parathyroid carcinomas are needed.
