Bootstrap analysis of the correlation between neutron skin thickness and the slope of symmetry energy
Authors: Pastore A.
Published: July 2020

This work illustrates the use of bootstrap methods to quantify the statistical uncertainties on the correlation coefficients between the slope of the symmetry energy and the neutron skin thickness in heavy nuclei. By using several energy density functionals, I discuss the density dependence of such a correlation and its evolution with isospin asymmetry. In particular, I observe that the correlation between the slope of the symmetry energy and the neutron skin is present not only at saturation density, but over a much larger density range.
COVID-19 ORDER PARAMETERS AND ORDER PARAMETER TIME CONSTANTS OF ITALY AND CHINA: A MODELING APPROACH BASED ON SYNERGETICS
Authors: FRANK T. D.
Published: July 2020

From a dynamical systems perspective, COVID-19 infectious disease emerges via an instability in human populations. Accordingly, the human population free of COVID-19 infected individuals is an unstable state and the dynamics away from that unstable state is a bifurcation. Recent research has determined COVID-19 relevant bifurcation parameters for various countries in terms of basic reproduction ratios. However, little is known about the relevant order parameters (synergetics) of COVID-19 bifurcations and the corresponding time constants. Those order parameters describe directions in compartment model spaces in which infection dynamics initially evolves. The corresponding time constants describe the speed of the dynamics along those directions. COVID-19 order parameters and their time constants are derived within a standard SEIR dynamical systems framework and determined explicitly for two published studies on COVID-19 trajectories in Italy and China. The results suggest the existence of certain relationships between order parameters, time constants, and reproduction ratios. However, the examples from Italy and China also suggest that COVID-19 order parameters and time constants in general depend on regional differences and the stage of the local COVID-19 epidemic under consideration. These findings may help to improve the forecasting of COVID-19 outbreaks in new hotspots around the world.

Authors: Patle Aarti , Singh Jyoti
Published: July 2020

Let [Formula: see text] be a polynomial ring in [Formula: see text] indeterminates with coefficients in the field [Formula: see text] of characteristic [Formula: see text] and [Formula: see text] be the ring of differential operators over [Formula: see text]. In this paper, we introduce the notion of generalized Eulerian [Formula: see text]-modules for characteristic [Formula: see text] and establish their properties. We show that if [Formula: see text] is any graded Lyubeznik functor on the category of modules over [Formula: see text] then [Formula: see text] is a generalized Eulerian [Formula: see text]-module. As a consequence, we prove that all socle elements of module [Formula: see text] are concentrated in degree [Formula: see text] where [Formula: see text] is an irrelevant maximal ideal of [Formula: see text].

The Manturov [Formula: see text]-group [Formula: see text] is the group generated by four elements [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] with defining relations [Formula: see text]. We apply the algebraic discrete Morse theory to calculate the Anick chain complex for [Formula: see text], evaluate the Hochschild cohomology groups of the group algebra [Formula: see text] with coefficients in all 1-dimensional bimodules over a field [Formula: see text] of characteristic zero, and derive its Hilbert and Poincare series.
Nijenhuis operators, product structures and complex structures on Lie–Yamaguti algebras
Authors: Sheng Yunhe , Zhao Jia , Zhou Yanqiu
Published: July 2020

In this paper, first, we study linear deformations of a Lie–Yamaguti algebra and introduce the notion of a Nijenhuis operator. Then we introduce the notion of a product structure on a Lie–Yamaguti algebra, which is a Nijenhuis operator [Formula: see text] satisfying [Formula: see text]. There is a product structure on a Lie–Yamaguti algebra if and only if the Lie–Yamaguti algebra is the direct sum of two subalgebras (as vector spaces). There are some special product structures, each of which corresponds to a special decomposition of the original Lie–Yamaguti algebra. In the same way, we introduce the notion of a complex structure on a Lie–Yamaguti algebra. Finally, we add a compatibility condition between a product structure and a complex structure to introduce the notion of a complex product structure on a Lie–Yamaguti algebra.
Static- and frequency-dependent NLO properties of dithienothiophene and thienothiophene bridges — A computational investigation
Authors: Yadav Sagar B. , Sekar Nagaiyan
Published: July 2020

We have explored detailed linear and nonlinear optical properties of push-pull systems bearing thienothiophene and dithienothiophene spacers. By using density functional theory (DFT), frequency-dependent strategies were applied to examine the polarizability ([Formula: see text] and hyperpolarizability ([Formula: see text] and [Formula: see text]. The set of global and range-separated hybrid functionals with different Hartree–Fock (HF) exchange percentage at two basis sets cc-pVDZ and cc-pVTZ were used to evaluate the nonlinear optical (NLO) properties. The observed trends in the absorption maxima supported by perturbation potential analysis; as the absorption maxima increases, the respective amplitude potential decreases. For the investigated compounds, [Formula: see text]-conjugation along with the type of substituted acceptor plays a crucial role in the enhancement of NLO properties. The presence of acceptor group and length of conjugation increase between the D and A group; the first- and second-order intrinsic hyperpolarizability increases, leads to enhanced first- as well as second-order hyperpolarizability. Bond length alternation (BLA)/bond order alteration (BOA) exploration suggested that compounds attain cyanine limit. The trends in NLO properties for investigated compounds are supported by chemical reactivity descriptors, hardness and hyperhardness analysis. The polarizability is linearly correlated with the hyperpolarizability parameters ([Formula: see text] and [Formula: see text] and shows a good regression coefficient by figures of merit analysis.

Organizational Re-Design for Business Model Innovation while Exploiting Digital Technologies: A Single Case Study of an Energy Company
Authors: Latilla Vito Maria Manfredi , Urbinati Andrea , Cavallo Angelo , Franzò Simone , Ghezzi Antonio
Published: July 2020

Digital technologies are bringing a wide spectrum of business opportunities as well as significant organizational challenges for incumbent companies operating in traditional industries such as the energy one. The diffusion of new technologies is changing the way energy solutions are consumed and experienced, while consumers increasingly take ownership of their consumption, acting as “prosumers”. In this evolving scenario, incumbents are urged to reshape their business models, explore new opportunities and change their organizational structures accordingly. Still, the required organizational re-design process that enables companies to undergo business model innovation (BMI) while exploiting digital technologies is partially neglected in literature. Hence, this study explores how established companies embrace organizational re-design process to innovate their business model. To this end, we leverage a single case study methodology focused on an incumbent energy company. Our findings show how the establishment of a business unit dedicated to digital technologies exploitation has enabled the company’s BMI. More specifically, we point at the critical role played by the know-how and the industrial capabilities to sustain not only the innovation activities of the new business unit, but also the overall company performance and the shift towards a renewed business model.
A Simple Model for the Wear Accumulation in Partial Slip Hertzian Contact
Authors: Argatov Ivan I. , Bae Joon Woo , Chai Young Suck
Published: July 2020

A two-dimensional wear contact problem with a stick zone is considered for a Hertzian cylindrical contact configuration and Archard’s equation of wear. A one-free-parameter simple model for the wear volume accumulation during the reciprocating wear process, which occurs in two symmetric variable slip zones, is developed and validated against numerical solutions available in the literature. The developed model takes into account the observed effect of non-monotonic evolution of the friction dissipated energy. The presented analytical modeling framework does not make use of any fitting parameters to be evaluated from experiments. The only free dimensionless parameter is suggested to be fixed based on numerical simulations for the maximum of the frictional damage that is proportional to the cumulative wear rate.

Published: July 2020

The characterization of the seafloor is a fundamental first step in informing resource management, marine spatial planning, conservation, fisheries, industry and research. Integrated Mapping for the Sustainable Development of Ireland's Marine Resource (INFOMAR), Ireland's national seabed mapping programme, delivers freely available, high-resolution seabed imagery derived from multibeam echosounder data in the Irish Exclusive Economic Zone. The European Union established the European Marine Observation and Data Network (EMODnet) Geology data portal, which provides harmonized broad-scale seabed substrate information for all European seas and confidence assessments of the information that underpins the geological interpretations. A multi-scale product has been produced using INFOMAR's high-resolution seabed substrate information at the 1:50 000 scale. As part of the Supporting Implementation of Maritime Spatial Planning in the Celtic Seas project, the EMODnet Geology seabed substrate data portal assisted in addressing the challenges associated with the implementation of the European Union's Marine Spatial Planning Directive. The seabed substrate data in the EMODnet Geology data portal were identified as a valuable tool for guiding the selection of sites for offshore wind farms in the Irish Sea and their subsequent characterization. This paper outlines the approach to delivering a multi-scale seabed substrate dataset for the Irish offshore and its applicability to marine spatial planning and the development of offshore energy resources.

Engineering geological models, projects and geotechnical risk
Authors: Baynes F. J. , Parry S. , Novotný J.
Published: July 2020

Engineering geological models (EGMs) comprise both conceptual ideas and observational data. The observational data are associated with aleatory uncertainty which can be reduced by acquiring more observations. The conceptual ideas are associated with epistemic uncertainty which can be reduced only if more knowledge is incorporated into the model. The conceptual ideas are the core of any EGM and provide the framework for the evaluation of the observational data. The most powerful capability of an EGM is the ability to anticipate what might be present at a project site and evaluate how the ground could adversely affect the project, i.e. when developed correctly, an EGM allows an evaluation of what might reasonably be foreseen at a site by an experienced contractor. This requires sophisticated conceptualization at an early stage in the project to anticipate what might be in the ground. Consequently, EGMs are much more than visualizations; they should represent an understanding of the geological conditions that are of engineering significance to the project, provide the framework for assembling engineering geological knowledge, support good geotechnical engineering decisions and allow an evaluation of potential geotechnical risks and possible project opportunities.

Dental implantation is the most popular method of restoring lost teeth. There are risk factors for dental implantation. These risk factors include the localization of residual filling material in the lumen of the mandibular canal in the selected jaw segment for implantation. A rare clinical case of dental implant placement with preservation of the safety zone relative to the residual siler in the mandibular canal is presented. A surgical guide was used for precise positioning. The treatment protocol was carried out without an immediate loading stage to monitor the possible development of symptoms.

Authors: Shi Xiaofeng
Published: July 2020

This paper is addressed to study local exact controllability to the trajectories of the Burgers–Fisher (BF) equation. By using the global Carleman estimate for the second-order parabolic operator, we establish the observable inequality and obtain the exact controllability to the trajectories of the linear system. Then, by local inverse theory, we consider the controllability result for the Burgers–Fisher equation.

Authors: Amiri-Farahani Leila , Sharifi-Heris Zahra , Mojab Faraz
Published: July 2020

Background and Objective. The topical human milk (THM) is one of the traditional remedies for various cases of injuries, ulcers, and infections for decades. No study was found reporting the adverse effects of human milk. The current study reviews the anti‐inflammatory properties of human milk when topically applied to dermal and optical diseases. Methods. The various datasets including Ovid, PubMed, Google Scholar, Science Direct, Magiran, Irandoc, SID, and IranMedex were searched from 1990 to 2018. From the 119 reviewed articles, 20 articles were selected to be included in the current article. Results. There is a consensus among the literature and ancient texts regarding the effectiveness of THM in curing the various types of skin damages, such as cord separation, atopic dermatitis, diaper dermatitis, conjunctivitis, scratches, insect bite, perineal ulcer, and nipple ulcer. However, the importance of its application has not been given much attention. Conclusion. According to the information obtained from the articles reviewed, the THM appears to be an effective, safe, and available treatment compared to conventional chemical treatments. This study suggests THM as an alternative remedy to minimize the frequent use of chemical‐based treatments. More research may be beneficial to reach certainty in terms of curative properties of THM in similar or different injuries in different populations.
Sevelamer Carbonate Crystal-Induced Colitis

Published: July 2020

Hyperphosphatemia is a common and well-described complication of end-stage renal disease. Despite strict dietary constraints and compliance, phosphate binders such as calcium acetate and/or sevelamer carbonate are also needed to treat secondary hyperparathyroidism. This case vignette describes an underrecognized adverse effect of a phosphate binder, sevelamer carbonate, inducing colitis in a 47-year-old male with insulin-dependent diabetes complicated by end-stage renal disease. He presented for recurrent abdominal pain with associated nausea and was found to have multiple circumferential lesions on computed tomography including distal ascending, transverse, and proximal descending colon. Colonoscopy demonstrated nearly obstructing lesions worrisome for colonic ischemia or inflammatory bowel disease. Pathological review of histology demonstrated ragged colonic mucosa with ulcerative debris and nonpolarizing crystalline material at the sites of ulceration, morphologically consistent with the phosphate binder, sevelamer carbonate. Sevelamer carbonate was discontinued, and the patient was transitioned to calcium carbonate with strict dietary restrictions. His symptoms improved with the cessation of sevelamer, and he was subsequently discharged home. He eventually underwent renal transplant without redevelopment of symptoms. Recognition of this underreported complication of sevelamer carbonate, phosphate binder, is of utmost importance in directing appropriate therapy with cessation of this medication in the setting of gastrointestinal complaints or more specifically enteritis and colitis. Clinicians providing care to end-stage renal patients taking either sevelamer and/or sodium polystyrene sulfonate should have increased awareness of the possible gastrointestinal side effects.
Ecological Retaining Wall for High‐Steep Slopes: A Case Study in the Ji‐Lai Expressway, Eastern China
Authors: Jiang Peng , Li Jin , Zuo Shen , Cui Xin Zhuang
Published: July 2020

Research on the retaining structures for high‐steep slopes is extremely significant because of its real‐world applications and far‐reaching implications. A flexible geocell‐reinforced ecological retaining wall as a high‐steep slope protection scheme was developed and applied to the slope protection project of the Ji‐Lai Expressway by analyzing the reinforcement mechanism of the geocell used. The lateral displacement and Earth pressure distribution on the flexible ecological retaining wall applied to the high‐steep slope were studied using finite element numerical simulations and verified using field experiments. Results reveal that the wall maximum horizontal displacement is 2/3 H away from the wall toe because of the replacement of the upper part of soil. There is an obvious bucking effect on the active Earth pressure around the stiffened site, and the flexible deformation of the retaining wall helped effectively release some of the Earth pressure. Consequently, the measured value is lower than the theoretical value. Through this case study, it is demonstrated that the flexible ecological retaining wall as a slope protection technology can be successfully applied to steep slopes with a height of more than 15 m. Moreover, it brings significant advantages for protecting the ecological environment and improving the highway landscape.

Published: July 2020

EXPAREL® has been used successfully to prolong postoperative pain control when applied as a wound infiltrate. EXPAREL® has not yet been approved for use in regional anesthesia to prolong postoperative pain control. We conducted a clinical case series of 4 patients using EXPAREL® for sciatic blocks via the popliteal fossa approach. Our results suggested that there is a large degree of variability in response to the medication. These inconsistent results and the possibility of bimodal kinetics creating analgesic gaps as seen in two of our patients indicate that more studies with larger sample size are needed to better characterize these phenomena and determine if more consistent results can be obtained in a future clinical trial.

Schistosomiasis is considered a neglected parasitic disease. Around 280,000 people die from it annually, and more than 779 million people are at risk of getting infected. The schistosome species which infect human beings are Schistosoma mansoni, Schistosoma haematobium, Schistosoma intercalatum, Schistosoma japonicum, Schistosoma guineensis, and Schistosoma mekongi. This disease is also of veterinary significance; the most important species being Schistosoma bovis since it causes the disease in around 160 million livestock in Africa and Asia. This work was aimed at designing and developing a genus-specific loop-mediated isothermal amplification (LAMP) method for detecting the most important schistosome species affecting humans and for the species-specific detection of S. bovis. Bioinformatics tools were used for primer design, and the LAMP method was standardised for detecting the ITS-1 region from S. intercalatum, S. haematobium, S. mansoni, S. japonicum, and S. bovis DNA (generic test) and the NADH 1 gene for specifically detecting S. bovis (at different DNA concentrations). Detection limits achieved were 1 pg DNA for S. mansoni, 0.1 pg for S. haematobium, 1 pg for S. intercalatum, and 10 pg for S. bovis. No amplification for S. japonicum DNA was obtained. The LAMP designed for the amplification of S. bovis NADH-1 worked specifically for this species, and no other DNA from other schistosome species included in the study was amplified. Two highly sensitive LAMP methods for detecting different Schistosoma species important for human and veterinary health were standardised. These methods could be very useful for the diagnosis and surveillance of schistosome infections.
A New Deep Convolutional Domain Adaptation Network for Bearing Fault Diagnosis under Different Working Conditions
Authors: Zhang Yongchao , Ren Zhaohui , Zhou Shihua
Published: July 2020

Effective fault diagnosis methods can ensure the safe and reliable operation of the machines. In recent years, deep learning technology has been applied to diagnose various mechanical equipment faults. However, in real industries, the data distribution under different working conditions is often different, which leads to serious degradation of diagnostic performance. In order to solve the issue, this study proposes a new deep convolutional domain adaptation network (DCDAN) method for bearing fault diagnosis. This method implements cross-domain fault diagnosis by using the labeled source domain data and the unlabeled target domain data as training data. In DCDAN, firstly, a convolutional neural network is applied to extract features of source domain data and target domain data. Then, the domain distribution discrepancy is reduced through minimizing probability distribution distance of multiple kernel maximum mean discrepancies (MK-MMD) and maximizing the domain recognition error of domain classifier. Finally, the source domain classification error is minimized. Extensive experiments on two rolling bearing datasets verify that the proposed method can implement accurate cross-domain fault diagnosis under different working conditions. The study may provide a promising tool for bearing fault diagnosis under different working conditions.
Coinfection of Aspergillus and Cryptococcus in Immunocompromised Host: A Case Report and Review of Literature
Authors: Awari Daniel W. , Shah Aditya S. , Sexton Amber M. , Sexton Matthew A.
Published: July 2020

Management of infections in the immunocompromised patient requires unique considerations that are not typically seen in the immunocompetent. Immunocompromised hosts require a broad set of differential diagnoses when presenting with febrile illness involving a wide variety of microbiology. Moreover, fungal infections are common, and cotreatment of fungal and bacterial infections occurs with regularity. Fungal coinfection, however, is rare. Here, we describe a patient with Aspergillus and recurrent Cryptococcus neoformans coinfection following completion of treatment for pulmonary cryptococcosis.
Role of Myokines in Myositis Pathogenesis and Their Potential to be New Therapeutic Targets in Idiopathic Inflammatory Myopathies
Authors: Mageriu Vlad , Manole Emilia , Bastian Alexandra E. , Staniceanu Florica
Published: July 2020

Idiopathic inflammatory myopathies (IIM) represent a heterogeneous group of autoimmune diseases whose treatment is often a challenge. Many patients, even after immunosuppressive therapy, do not respond to treatment, so new alternatives have been sought for this. Therefore, other signaling pathways that could contribute to the pathogenesis of myositis have been investigated, such as the expression of myokines in skeletal muscle in response to the inflammatory process. In this review, we will refer to these muscle cytokines that are overexpressed or downregulated in skeletal muscle in patients with various forms of IIM, thus being able to contribute to the maintenance of the autoimmune process. Some muscle cytokines, through their antagonistic action, may be a helpful contributor to the disease modulation, and thus, they could represent personalized treatment targets. Here, we consider the main myokines involved in the pathogenesis of myositis, expressing our view on the possibility of using them as potential therapeutic targets: interleukins IL-6, IL-15, and IL-18; chemokines CXCL10, CCL2, CCL3, CCL4, CCL5, and CCL20; myostatin; follistatin; decorin; osteonectin; and insulin-like 6. An interesting topic regarding the complex connection between myokines and noninflammatory pathways implied in IIM has also been briefly described, because it is an important scientific approach to the pathogenesis of IIM and can be a therapeutic alternative to be considered, especially for the patients who do not respond to immunosuppressive treatment.

Objective: Functional hepatic reserve is important when considering sequential tyrosine kinase inhibitor (TKI) therapy for patients with advanced hepatocellular carcinoma (HCC). We assessed albumin-bilirubin (ALBI) score and Child-Pugh class as indices of liver function during sorafenib and lenvatinib treatment. Methods: A total of 212 patients with advanced HCC and Child-Pugh class A status who initiated TKI treatment at our hospital were enrolled in this retrospective cohort study. A total of 74 of the 212 patients underwent blood testing before starting sorafenib treatment and every 2 months after treatment initiation. Results: In 74 patients, the median ALBI score before TKI treatment was –2.53, and after 2, 4, and 6 months it was –2.45, –2.44, and –2.36, respectively. ALBI scores tended to increase during TKI therapy. Among patients who experienced a time to progression ≤3.8 months, ALBI scores had increased 2 months after treatment initiation, and at 4 and 6 months, significant differences were observed (p < 0.01). In all 212 patients, during first-line TKI treatment, the Child-Pugh class deteriorated to B or C in 72.2% of the patients, and the median time to deterioration was 3.9 months. The factors in hepatic reserve deterioration were serum albumin ≤3.8 g/dL and the presence of macroscopic vascular invasion. The hepatic reserve of 68.0% of the patients with deterioration of liver function recovered to Child-Pugh class A following dose reduction, drug withdrawal, or treatment intended for recovery of liver function. Conclusion: ALBI scores deteriorate in patients treated with TKIs, suggesting that tumor progression induces these changes.

Bone involvement in Hodgkin lymphoma (HL) is rare. The differential diagnosis between HL bone localization and other malignant or benign skeletal diseases is challenging. We report the case of a girl affected by classic HL, initially staged IVA because of supradiaphragmatic lymph nodes and skeletal involvement. After 6 ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) cycles, positron emission tomography (PET) showed a complete metabolic response of the nodal localizations and a persistent, high metabolic activity of bone lesions. Salvage treatment followed by autologous stem cell transplant was carried out. After the transplant, the bone lesions maintained a high metabolic activity at PET. A targeted bone biopsy led to the diagnosis of a fibrous dysplasia excluding the presence of HL. To our knowledge, the concomitant presence of HL and fibrous dysplasia has not been previously reported. An in-depth evaluation of disease response to frontline treatment with a biopsy of the PET-hypercaptant bone lesions could have avoided overtreatment in this patient.

Objective: To analyze decision-making in patients with male urinary incontinence (SUI) in centers of expertise. The artificial urinary sphincter (AUS) remains the gold standard for male patients with moderate to severe SUI but adjustable male slings are a minimally invasive treatment option with good results, hence without a high level of evidence regarding the optimal patient selection. Materials and Methods: In total, 220 patients (88 AUS; 132 adjustable slings) were investigated from the DOMINO database that underwent surgery between 2010 and 2012 in 5 urological departments that offer adjustable sling systems as well as AUS systems for patients with moderate to severe urinary incontinence. For statistical analysis, the Mann-Whitney U test was used to identify differences between both groups. Results: Patients selected for an adjustable male sling were less likely to have a neurological disease (5.3 vs. 9.1%; p = 0.030), a prior urethral stricture (22.7 vs. 50.0%; p = 0.001), a prior incontinence surgery (24.4 vs. 45.5%; p = 0.01), or a prior radiation therapy (26.5 vs. 40.1%; p = 0.001). The severity of preoperative incontinence was higher in patients selected for an AUS with a mean pad usage per day of 7.60 versus 5.80 (p < 0.001). Mean postoperative pad usage and patients’ subjective perception were comparable in both groups. Conclusion: In centers offering both options, the decision-making is mainly based upon presence of radiation therapy and previous failed incontinence surgery. Despite the more complex patient cohort selected for an AUS implantation with a possible impact on the postoperative outcome, the functional results seem to be comparable indicating a proper preoperative patient assessment and selection in this cohort.

Este artigo traz parte da investigação de doutorado que aborda a integração das artes na formação de professores de Arte da Educação Básica no Brasil. A incongruência existente entre o hibridismo que caracteriza parte da produção artística contemporânea e a maneira como se processa o ensino das artes nos cursos superiores, em contraposição a uma atuação docente polivalente na educação infantil e no ensino fundamental, suscita uma reflexão crítica mais profunda. Desde 1960 a Educação Básica tem privilegiado um ensino artístico polivalente, contexto reafirmado pela recente BNCC (Base Nacional Comum Curricular), enquanto as Diretrizes Curriculares para o Ensino Superior valorizam uma formação específica em cada uma das linguagens artísticas. Nesse sentido o presente artigo se propõe a analisar e compreender a trajetória dos ordenamentos destinados ao ensino artístico com o intento de compreender as suas incongruências, o que precisa ser remodelado ou mantido e como adequar as matrizes curriculares dos cursos de arte a esse conjunto ordenatório
Cantor e cantor de microfone

No artigo há um estudo conceitual sobre o canto. Por conta da indústria da cultura, o canto milenar passou a ser chamado de canto lírico. Essa expressão, contudo, não faz sentido. O canto da indústria da cultura se impôs soberano na ditadura da opinião pública. Mas é um tipo de história recente de cerca de um século. O artigo propõe que, numa perspectiva histórico-musicológica, mais adequado seria chamar o canto na arte e na arte popular simplesmente de canto, já o canto na indústria da cultura de canto de microfone.

The objective of this study was to investigate the effects of Caulerpa racemosa (Agardh, 1873) polysaccharides (CRP) on non-specific immunity of the white shrimp, Litopenaeus vannamei (Boone, 1931). The extracted polysaccharide consists of galactose, glucose, and mannose. Total polyphenolic compound and total flavonoids content in CRP were determined. In vitro CRP treatment did not alter cell viability of haemocytes and significantly activated phenoloxidase (PO) activity, superoxide anion production capacity, phagocytic rate, and index in haemocytes. Immune parameters, such as total haemocyte count, PO activity, phagocytosis, and superoxide anion production, were significantly elevated in CRP-fed shrimp during the rearing period. Malondialdehyde levels in the hepatopancreas of CRP-fed shrimp were lower than in control shrimp from day 7 to day 28. These results show that CRP exhibits antioxidant activity and can activate immune responses of white shrimp in vitro and in vivo. Therefore, CRP can be considered a functional feed additive to improve white shrimp immunity.

Published: July 2020

This article discusses the findings of an empirical study, the first to investigate Taiwanese and Hong Kong parents’ perspectives on their disabled children’s play. The study employed an online survey to explore parents’ views on (a) the value of play for their child; (b) their child’s experiences of play (e.g. where and with whom they play); c) what, if any, barriers their child experiences in/to play. Our analysis shows that disabled children living in Taiwan and Hong Kong face many of the same barriers to play as disabled children elsewhere (e.g. in the West), but that these barriers have distinct ‘local formations’ resulting from, for example, high-density urban-living, family-based welfare systems, prevailing gendered family roles/relations, persistent social stigma towards disabled people and their families and intense valuing of academic achieve ment within Chinese cultures. We present this article as an original contribution to Disabled Children’s Childhood Studies, to Global Disability Studies and Play Studies. The article concludes by mapping an agenda for further research into access to and inclusion in play for disabled children living in East Asia.

Published: July 2020

A new species of pincer wasps, Bocchus schmalhauseni sp. nov. (Dryinidae) is described from Rovno amber (Ukraine). The amber piece was collected in the Vladimirets District in the north-west of the Rovno region. Taking into account this new record, a total of five species of Dryinidae are registered from Rovno amber. A key to the fossil species of Bocchus Ashmead is presented. The possible reasons for the different distribution of Dryinus species on both coasts of Subparathetys are discussed.

Published: July 2020

A new species of Alfieriella Wittmer, 1935 (Coleoptera, Cryptophagidae), Alfieriella senguptai sp. n. from China and India, is described. This is the first formal record of the genus Alfieriella and the tribe Hypocoprini from the Himalayan region. Alfieriella senguptai is the largest member of Alfieriella, and its presence in a cold, high-altitude environment conforms to Bergmann’s rule. The distribution of the genus Alfieriella may be associated with the breakup of the Tethys Ocean and the origin of A. senguptai influenced by the Himalayan orogeny. A distribution map and a key to species of Alfieriella are also provided.
How Protesters and the State Learn From One Another: Spiraling Repertoires of Contention and Repression in Ukraine, 1990-2014
Authors: Zelinska Olga
Published: July 2020

This article employs a contentious politics framework to examine the mobilization–repression nexus as it occurred in Ukraine from the 1990 Revolution on Granite, through the 2000-2001 Ukraine without Kuchma campaign and the 2004 Orange Revolution, to the 2013-2014 Euromaidan movement. Comparative analysis of these four cases suggests that developments in both the contentious and repressive repertoires resembled spirals: each campaign became more complex and of longer duration than the last, and each was driven by the repeated protester–government interactions and by the political, economic, and technological environment that changed over time. In the transit from autocracy to democracy, Ukrainian activists adopted and “normalized” political protest much more quickly than did the authorities. The activists creatively innovated as they borrowed from earlier dissent traditions and from other social movements abroad. For the government, the process of learning how to manage contention with means other than their usual repression tactics was much longer, and it is not over. As it slowly transits from Soviet past to democracy, Ukraine continues its development into a “social movement society.”
The Shortcomings of Transparency for Democracy
Authors: Schudson Michael
Published: July 2020

“Transparency” has become a widely recognized, even taken for granted, value in contemporary democracies, but this has been true only since the 1970s. For all of the obvious virtues of transparency for democracy, they have not always been recognized or they have been recognized, as in the U.S. Freedom of Information Act of 1966, with significant qualifications. This essay catalogs important shortcomings of transparency for democracy, as when it clashes with national security, personal privacy, and the importance of maintaining the capacity of government officials to talk frankly with one another without fear that half-formulated ideas, thoughts, and proposals will become public. And when government information becomes public, that does not make it equally available to all—publicity is not in itself democratic, as public information (as in open legislative committee hearings) is more readily accessed by empowered groups with lobbyists able to attend and monitor the provision of the information. Transparency is an element in democratic government, but it is by no means a perfect emblem of democracy.
The Effects of Fasting Status on the Relative Risk of Pulmonary Aspiration in Acute Care Surgery Patients

Background

Acute care surgery patients are often unfasted at the time of surgery, presenting a unique opportunity to study the effects of fasting on the risk of pulmonary aspiration. We aimed to determine the relative risk of aspiration in patients who were fasted at the time of surgery according to guidelines versus those in an unfasted state.

Methods

A retrospective chart review of 100 patients who underwent appendectomy (n = 76) or exploratory laparotomy (n = 24) was conducted at a single institution in 2016-2017. Using the American Society of Anesthesiologists (ASA) Practice Guidelines for Preoperative Fasting, patients were stratified into study and control groups according to whether they were unfasted (nothing by mouth for <8 hours prior to surgery) or fasted (nothing by mouth for >8 hours prior to surgery). Data controlled for patients’ age, sex, body mass index (BMI), most recent hemoglobin A1c, presence of gastroesophageal reflux disease (GERD), and presence of hiatal hernia.

Results

Of the 76 patients who underwent appendectomy, 15% were unfasted with a total of 0 aspiration events ( P < .001). Of the 24 patients who underwent exploratory laparotomy, 42% were unfasted with a total of 0 aspiration events ( P < .001). This yields a relative risk of pulmonary aspiration of 1.0 (absolute risk of 0) in both the study and control groups.

Discussion

In an acute care surgery population including patients who were not fasted according to guidelines, there was no increase in the risk of pulmonary aspiration.

Published: July 2020

Analysis of structural and dynamic properties of water in suspensions of liposomes composed from 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) in three phase states (gel, rippled gel, liquid crystalline phase) by means of terahertz time-domain spectroscopy in 0.3–3.3 THz range was conducted in the current work. Fraction of free water molecules in DPPC liposome suspension was shown to decrease with temperature (compared to the analogous aqueous solution without liposomes), and intermolecular water binding was enhanced. The most crucial changes occur during gel-rippled gel phase transition (pretransition): at temperatures below pretransition point, liposomes alleviate water binding degree, while at temperatures above the transition point, they enhance water binding. This study has demonstrated the high information content of the terahertz time-domain spectroscopy method for exploring the hydration properties of phospholipids in water.
Can High-Dimensional Questionnaires Resolve the Ipsativity Issue of Forced-Choice Response Formats?
Authors: Schulte Niklas , Holling Heinz , Bürkner Paul-Christian
Published: July 2020

Forced-choice questionnaires can prevent faking and other response biases typically associated with rating scales. However, the derived trait scores are often unreliable and ipsative, making interindividual comparisons in high-stakes situations impossible. Several studies suggest that these problems vanish if the number of measured traits is high. To determine the necessary number of traits under varying sample sizes, factor loadings, and intertrait correlations, simulations were performed for the two most widely used scoring methods, namely the classical (ipsative) approach and Thurstonian item response theory (IRT) models. Results demonstrate that while especially Thurstonian IRT models perform well under ideal conditions, both methods yield insufficient reliabilities in most conditions resembling applied contexts. Moreover, not only the classical estimates but also the Thurstonian IRT estimates for questionnaires with equally keyed items remain (partially) ipsative, even when the number of traits is very high (i.e., 30). This result not only questions earlier assumptions regarding the use of classical scores in high-dimensional questionnaires, but it also raises doubts about many validation studies on Thurstonian IRT models because correlations of (partially) ipsative scores with external criteria cannot be interpreted in a usual way.
