Authors: Lian Dong-Sheng , Chen Xiang-Yuan , Zeng Hua-Song , Wang Yan-Yi 
Published: May 2020

Abstract
Most hereditary diseases are incurable, but their deterioration could be delayed or stopped if diagnosed timely. It is thus imperative to explore the state-of-the-art and high-efficient diagnostic techniques for precise analysis of the symptoms or early diagnosis of pre-symptoms. Diagnostics based on clinical presentations, hard to distinguish different phenotypes of the same genotype, or different genotypes displaying similar phenotypes, are incapable of pre-warning the disease status. Molecular diagnosis is ahead of harmful phenotype exhibition. However, conventional gold-standard molecular classifications, such as karyotype analysis, Southern blotting (SB) and sequencing, suffer drawbacks like low automation, low throughput, prolonged duration, being labor intensive and high cost. Also, deficiency in flexibility and diversity is observed to accommodate the development of precise and individualized diagnostics. The aforementioned pitfalls make them unadaptable to the increasing clinical demand for detecting and interpreting numerous samples in a rapid, accurate, high-throughput and cost-effective manner. Nevertheless, capillary electrophoresis based on genetic information analysis, with advantages of automation, high speed, high throughput, high efficiency, high resolution, digitization, versatility, miniature and cost-efficiency, coupled with flexible-designed PCR strategies in sample preparation (PCR-CE), exhibit an excellent power in deciphering cryptic molecular information of superficial symptoms of genetic diseases, and can analyze in parallel a large number of samples in a single PCR-CE, thereby providing an alternative, accurate, customized and timely diagnostic tool for routine screening of clinical samples on a large scale. Thus, the present study focuses on CE-based nucleic acid analysis used for inherited disease diagnosis. Also, the limitations and challenges of this PCR-CE for diagnosing hereditary diseases are discussed.
N,N′-Bis[2-hydroxynaphthylidene]/[2-methoxybenzylidene]amino]oxamides and their divalent manganese complexes: Isolation, spectral characterization, morphology, antibacterial and cytotoxicity against leukemia cells
Authors: Ahmed Ayman H. 
Published: May 2020

AbstractManganese(ii) complexes of oxalic dihydrazones {N,N′-bis[2-hydroxynaphthylidene]amino]oxamide (BHO) andN,N′-bis[2-methoxybenzylidene]amino]oxamide (BMO)} have been synthesized by a general methodology. Hydrazone ligands (BHO and BMO) were obtained by the condensation of oxalic dihydrazide with 2-hydroxynaphthalene-1-carbaldehyde and 2-methoxybenzaldehyde. From the data obtained from the spectral (mass, IR,1H-NMR, UV-Vis, ESR), magnetic and thermal measurements in addition to the elemental analyses (CHNM), the structures of ligands and their complexes have been determined. The scanning electron microscope (SEM) was used to characterize the morphology of the complex surface. The ligands coordinated with the metal center in a bi-dentate way forming binuclear Mn–BHO and mononuclear Mn–BMO complexes. The manganese complexes are proposed to have octahedral stereochemistry. The ligands and manganese(ii) complexes have been assessed for their antibacterial and antileukemia activities. The proliferation hindrance for the free ligands was enhanced upon coordination with the manganese(ii) ions.
Physicochemical properties of selected herbicidal products containing nicosulfuron as an active ingredient

Published: May 2020

AbstractNicosulfuron is a herbicide used for plant protection. This paper presents the results of research on the physicochemical properties of three herbicidal preparations containing nicosulfuron as the active substance by measuring and comparing its concentration by the chromatographic method. These preparations are in the form of a concentrated suspension intended for dilution with water, and due to the fact that nicosulfuron contained in the tested preparations is sensitive to water quality, while checking the physicochemical properties of the preparations, a dispersion for soft (pH: 5–7) and hard (pH: 8–9) water was also determined. It is important to note that high content of mineral salts in water may have a negative effect on the biological activity of the substance. In addition, the use of herbicides does not only apply to the use of appropriate dilutions, which are effective and not harmful to the environment. However, it is also important to consider specific farmer and equipment used, so that the preparation is easy to use and does not adversely affect the kit used for spraying. This study has shown that depending on the preparation used based on the amount of active substance 40 g/l, the amount of nicosulfuron varies. The test indicators in the form of pH and density are similar, while during the tested dispersion, differences depending on the tested water were observed (sediments were observed in only one preparation tested). Differences depending on the occurrence of sediments in the water used, both at 0 and 24 h, are signaling in favor of the soft water. Therefore, it is important to assess the hardness of the water, which in turn guarantees a reduction of the amount of deposits and protection of agricultural equipment used for spraying.
Discursive Constraints of Teasing: Constructing Professionality via Teasing in Chinese Entertainment Interviews
Authors: Gong Lili , Ran Yongping 
Published: May 2020

AbstractTeasing can be approached as a linguistic resource for examining the interpersonal issues of im/ politeness and face, or as a discursive strategy for displaying relationships or constructing social identities. However, studies have underestimated the discursive constraints of teasing in specific contexts. Meanwhile, a majority of teasing studies were based on Western cultures and did not pay sufficient attention to the variety of teasing across cultures. By collecting data from two Chinese entertainment interviews, where the interviewer employs teasing frequently for performing institutional roles, this study examined how teasing functions to assist the interviewer to complete communicative goals, and explored the discursive constraints of teasing in media context. Data analysis exemplified how teasing helped the interviewer to manage an interview event, obtain the guest’s disclosure and seek audience involvement, helping to construct the interviewer’s professionality. Implications for understanding the discursive features of teasing in the Chinese media context were addressed.
Learner Autonomy in the National English Language Curricula for Chinese Universities 1978—2007: A Historical Analysis
Authors: Pu Shi 
Published: May 2020

AbstractThis historical study investigates the concept of learner autonomy in the national English language curricula for Chinese universities. It seeks to understand the meaning of learner autonomy in China and the intentionality of promoting this concept through the curricula from 1978 to 2007. By adopting Quentin Skinner’s intentionalist approach to analyzing the history of ideas, this study conducted a systematic document analysis of three national curricula in relation to their linguistic and practical contexts constituted of 169 Chinese academic articles in total. The study revealed that learner autonomy mainly referred to students’ motivation and ability to work hard on their own outside the classroom in the Chinese context. Importing this concept, however, caused ideological confusion and exacerbated the disempowerment of teachers within the dynamics of China’s English language education at the tertiary level. The study raises awareness for borrowing concepts across different cultural contexts and has implications for research, policymaking, teacher development, and pedagogical practice in second language education in China.
Investigating the effects of sponsorship and forewarning disclosures on recipients’ reactance
Authors: Weitzl Wolfgang J. , Seiffert-Brockmann Jens , Einwiller Sabine 
Published: May 2020

Abstract
Due to increasing consumer skepticism towards promotional messages, companies are looking for new ways to communicate with their target audiences in a less obtrusive way than traditional advertising. Sponsored content disseminated on the online portals of newspapers (i. e., online advertorials) is regarded as a promising way to promote products and brands. Regulations require communicators to inform consumers about the commercial nature of this ‘masked’ persuasion attempt by including an explicit sponsorship disclosure (i. e., a ‘Sponsored’ label). This study demonstrates that such an explicit advertising cue may not be enough to alert recipients. Furthermore, this study investigates the effects of promotional messages by means of a 2 (no disclosure vs. disclosure) x 2 (no forewarning vs. forewarning) experiment. Results show that both (i) foregoing instructions aimed at activating consumers’ persuasion knowledge (i. e., an additional forewarning message) and (ii) recipients’ prior media literacy can foster the effect of sponsorship disclosures in triggering situational distrust towards brand-related content, and in turn, increasing consumers’ reactance.
The concept of integrated communication under close scrutiny: A study on the effects of congruity-based tactics
Authors: Kirchenbauer Alena 
Published: May 2020

Abstract
This study examines how consumers react to a Facebook post that is completely, moderately or not at all in conflict with a brand-typical TV clip. It thus analyzes the need for congruity between the offline and online advertising activities of a brand and draws on the literature of integrated communication, schema incongruity theory and advertising effectiveness. Results of an online experiment with 131 participants and a 2 (content: congruent vs. incongruent) by 2 (stylistic devices: congruent vs. incongruent) between-subjects design provide first insights into the modeling of (in)congruity based on integrated communication. Thus, the article presents a first attempt to conceptualize (in)congruity in advertising through a combination of content and stylistic devices. In addition to this research agenda, the manuscript offers implications for advertising practice.
Good journalist, bad blogger? A study on the labeling of paid content in blogs and journalism
Authors: Hoffjann Olaf , Haidukiewicz Oliver 
Published: May 2020

Abstract
This study examines whether journalists and bloggers label paid content. In Germany, as in many other countries, advertorials have to be designated as advertising to enable the target audience to identify the promotional character of the content. This applies both to the traditional mass media and to blogs, for which advertorials provide a key source of income. To date, there have been no empirical findings on the designation practice based on a comparison of journalists and bloggers. The present study presents an online survey in Germany completed by 936 journalists and 463 bloggers in 2017. The results indicate that, in fact, bloggers do not label advertorials less frequently than journalists do: 91.6 % of bloggers and 91.7 % of journalists stated that they label paid content as advertising.
On the equivalence between noncollapsing and bounded entropy for ancient solutions to the Ricci flow
Authors: Zhang Yongjia 
Published: May 2020

Abstract
As a continuation of a previous paper, we prove Perelman’s assertion, that is, for ancient solutions to the Ricci flow with bounded nonnegative curvature operator, uniformly bounded entropy is equivalent to κ-noncollapsing on all scales. We also establish an equality between the asymptotic entropy and the asymptotic reduced volume, which is a result similar to a paper by Xu (2017), where he assumes the Type I curvature bound.
Half-space theorems for the Allen–Cahn equation and related problems

Published: May 2020

Abstract
In this paper we obtain rigidity results for a non-constant entire solution u of the Allen–Cahn equation in

{\mathbb{R}^{n}}

, whose level set

{\{u=0\}}

is contained
in a half-space. If

{n\leq 3}

, we prove that the solution must be one-dimensional. In dimension

{n\geq 4}

, we prove that either the solution is one-dimensional or stays below a one-dimensional solution and converges to it after suitable translations. Some generalizations to one phase free boundary problems are also obtained.
A great pre-eclampsia masquerader. Hemophagocytic lymphohistiocytosis (HLH) presenting in pregnancy
Authors: Toscano Marika , Westen Elizabeth , Hollenbach Stefanie J. , Perkins Archibald S. , Thornburg Loralei L. 
Published: May 2020

Abstract

Background
Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening disease. It is characterized by impaired natural killer cell and cytotoxic lymphocyte function leading to dysregulated macrophage phagocytosis of erythrocytes, leukocytes and platelets. Coupled with a massive release of cytokines this rapidly leads to multi-organ failure and mortality if not treated promptly.

Case presentation
We report a case of pregnancy-associated, treatment-resistant HLH with no identified risk factors.

Conclusion
It is likely that HLH is an unrecognized cause of intractable fever and disseminated intravascular coagulation (DIC) in young pregnant women and it should be included in the differential diagnosis when patients do not respond to typical therapies. High serum ferritin should further prompt consideration of this diagnosis. This rare disease is often not thought of and many gynecologist obstetricians have never heard of it, making this case report of essential importance to reignite the interest in HLH, particularly when it occurs during pregnancy.
Generalized parabolic Marcinkiewicz integrals associated with polynomial compound curves with rough kernels
Authors: Ali Mohammed , Katatbeh Qutaibeh 
Published: May 2020

AbstractIn this article, we study the generalized parabolic parametric Marcinkiewicz integral operators{ {\mathcal M} }_{{\Omega },h,{\Phi },\lambda }^{(r)}related to polynomial compound curves. Under some weak conditions on the kernels, we establish appropriate estimates of these operators. By the virtue of the obtained estimates along with an extrapolation argument, we give the boundedness of the aforementioned operators from Triebel-Lizorkin spaces toLpspaces under weaker conditions onΩandh. Our results represent significant improvements and natural extensions of what was known previously.
The Invisible Networks of Global Production: Re-Imagining the Global Value Chain in Legal Research
Authors: Beckers Anna 
Published: May 2020

Abstract
Reviewing the burgeoning legal scholarship on global value chains to delineate the legal image of the global value chain and then comparing this legal image with images on global production in neighbouring social sciences research, in particular the Global Commodity Chain/Global Value Chain and the Global Production Network approach, this article reveals that legal research strongly aligns with the value chain image, but takes less account of the production-centric network image. The article then outlines a research agenda for legal research that departs from a network perspective on global production. To that end, it proposes that re-imagining the law in a world of global production networks requires a focus in legal research on the legal construction of global production and its infrastructure and a stronger contextualization of governance obligations and liability rules in the light of the issue-specific legal rules that apply to said infrastructure.
Effectiveness of Corona Lockdowns: Evidence for a Number of Countries
Authors: Homburg Stefan 
Published: May 2020

Abstract
The paper assesses the effectiveness of the large-scale lockdowns that took place during the SARS-CoV-2 (corona) pandemic. Countries considered include the United States, South Korea, Germany, Austria, Switzerland, Italy, Spain, and Sweden. Our research strategy utilizes the fact that fatal outcomes follow infections with a delay of 23 days. Therefore, the dates of the actual infections can be inferred from the data. The results suggest that lockdowns were superfluous and ineffective.
Alvis–Curtis duality for representations of reductive groups with Frobenius maps
Authors: Dong Junbin 
Published: May 2020

Abstract
We generalize the Alvis–Curtis duality to the abstract representations of reductive groups with Frobenius maps. Similar to the case of representations of finite reductive groups, we show that the Alvis–Curtis duality of infinite type, which we define in this paper, also interchanges the irreducible representations in the principal representation category.
Microdatabase Direct Investment (MiDi) – A full survey of German inward and outward investment
Authors: Blank Sven , Lipponer Alexander , Schild Christopher-J. , Scholz Dietmar 
Published: May 2020

Abstract
The research dataset “Microdatabase Direct Investment” is a dataset on foreign direct investment (FDI) stocks based on the official German FDI microdata. The original data are collected on an annual basis by the Deutsche Bundesbank to compile the FDI stock statistics for Germany. Making this official data available to researchers via the MiDi database provides a research dataset on direct investment relationships that is unique both in terms of data available and in the depth of cross-border shareholdings, covering all years since 1999. In this paper, we explain the central properties of this dataset and demonstrate its usefulness for research.

AbstractStabilization of zero-valent CuNi nanoparticles (NPs) supported on Cicer
arietenum (CP) is reported here for the reduction and removal of
persistent organic pollutants. The functional groups and interactions of NPs with the
CP were determined by ATR-FTIR. The crystallinity, morphology, and the elemental
composition of the samples were determined through powder XRD, FESEM, and EDS
techniques, respectively. The XRD spectrum displayed a sharp crystalline peak at 43.9
for CuNi. The Cu and Ni zero-valent NPs displayed a peak at almost the same region,
and thus, both the peaks are merged and appeared as a single peak. The chemical
reduction/degradation of eight model pollutants, viz., 2-nitrophenol (ONP),
3-nitrophenol (MNP), 4-nitrophenol (PNP), 2,4-dinitrophenol (DNP), methyl orange
(MO), congo red (CR), methylene blue (MB), and rhodamine B (RB) were carried out in
the presence of NaBH4. The kapp value of 0.1 mM 4NP was highest which was 1.8 ×
10−1 min−1 while the slowest rate was observed
for CR and RB with kapp 5.5 × 10−3 and 5.4 ×
10−3 min−1 respectively. This article helps in
the removal of toxic organic pollutants through green supported NPs.
The historical resources of China’s model: Relevance to the present
Authors: Hrubec Marek 
Published: May 2020

Abstract
The article focuses on the historical resources of the China’s model. Understanding the model is one of necessary preconditions of an analysis of China’s dynamic rise and development in recent decades. First, the article analyses the concept of historical development of multiple civilisations and modernities. It then examines the characteristics of China’s old civilisation and the associated model. It ends by showing how the historical Silk Road lives on in an updated modernised global version.
Building narrative identity: Episodic value and its identity-forming structure within personal and social contexts
Authors: Yi Huiyuhl 
Published: May 2020

Abstract
In this essay, I develop the concept of episodic value, which describes a form of value connected to a particular object or individual expressed and delivered through a narrative. Narrative can bestow special kinds of value on objects, as exemplified by auction articles or museum collections. To clarify the nature of episodic value, I show how the notion of episodic value fundamentally differs from the traditional axiological picture. I extend my discussion of episodic value to argue that the notion of episodic value readily incorporates the role of narratives into the construction of identity in personal and social contexts. My main contentions are twofold. First, events or experiences from our personal narratives are episodically valuable insofar as they contribute to shaping our narrative identities. Second, when engaged in a collective action, we write a joint narrative with other participants that confers special meanings on the actions of each participant.
Los datos censales en el estudio del multilingüismo y la migración: Cuestiones ideológicas y consecuencias epistémicas
Authors: Leeman Jennifer 
Published: May 2020

Resumen
Dado el uso frecuente de las estadísticas censales en los estudios del multilingüismo, este artículo argumenta que es necesario examinarlas desde una perspectiva crítica que tenga en cuenta la relación entrelazada de los aspectos metodológicos e ideológicos de los censos. En contraste con los estudios previos que por lo general han examinado uno o dos elementos de la producción de un censo, como por ejemplo la selección de temas y categorías a incluirse, la formulación de las preguntas, o el procesamiento de los datos, este artículo analiza críticamente la problemática en cada paso del censo, enfatizando cómo están entrelazados los aspectos administrativos, epistémicos y ideológicos a lo largo del proceso y presentando ejemplos ilustrativos. Ya que es imposible separar las estadísticas de sus orígenes como instrumento del Estado y componente del discurso oficial, al utilizarlas en los estudios académicos nos urge examinarlas críticamente para entender qué ideologías encarnan y reproducen.
Significado social de las actitudes lingüísticas, la red social y las variables de pequeña escala en los estudios de inmigración: combinación de métodos cualitativos y cuantitativos
Authors: von Essen María Clara 
Published: May 2020

Resumen
Este trabajo se centra en la acomodación de un grupo de inmigrantes argentinos de Buenos Aires que residen en la ciudad de Málaga (España). En este estudio, analizamos todos los grupos etarios: jóvenes, adultos y mayores, e instauramos una combinación nueva de métodos de análisis cualitativo y cuantitativo que nos permitió entender y describir, en profundidad, la complejidad de los procesos de acomodación. A través de esta nueva metodología de observación (cualitativa y cuantitativa), concluimos que es necesario llevar a cabo un análisis complejo de los inmigrantes que tenga en cuenta métodos de observación directa e indirecta, su peso explicativo y su grado de coherencia. A su vez, establecimos que deben considerarse variables intermedias o de pequeña escala como las actitudes lingüísticas, la red social, la edad de llegada, los planes de volver a Argentina y, sobre todo, la percepción de la propia identidad. El análisis complejo de este grupo de inmigrantes nos ha permitido comprender su comportamiento lingüístico y las ideologías relacionadas con la acomodación lingüística y su significado social.
