Algebraic and qualitative remarks about the family yy′ = (αxm+k–1 + βxm–k–1)y + γx2m–2k–1
Authors: Rodríguez-Contreras Jorge , Acosta-Humánez Primitivo B. , Reyes-Linero Alberto 
Published: November 2019

Abstract
The aim of this paper is the analysis, from algebraic point of view and singularities studies, of the 5-parametric family of differential equations

$$\begin{array}{}
\displaystyle
yy'=(\alpha x^{m+k-1}+\beta x^{m-k-1})y+\gamma x^{2m-2k-1}, \quad y'=\frac{dy}{dx}
\end{array}$$
where a, b, c ∈ ℂ, m, k ∈ ℤ and

$$\begin{array}{}
\displaystyle
\alpha=a(2m+k) \quad \beta=b(2m-k), \quad \gamma=-(a^2mx^{4k}+cx^{2k}+b^2m).
\end{array}$$
This family is very important because include Van Der Pol equation. Moreover, this family seems to appear as exercise in the celebrated book of Polyanin and Zaitsev. Unfortunately, the exercise presented a typo which does not allow to solve correctly it. We present the corrected exercise, which corresponds to the title of this paper. We solve the exercise and afterwards we make algebraic and of singularities studies to this family of differential equations.
F-biharmonic maps into general Riemannian manifolds
Authors: Mi Rong 
Published: November 2019

Abstract
Let ψ:(M, g) → (N, h) be a map between Riemannian manifolds (M, g) and (N, h). We introduce the notion of the F-bienergy functional

$$\begin{array}{}
\displaystyle
E_{F,2}(\psi)=\int\limits_{M}F\left(\frac{|\tau(\psi)|^{2}}{2}\right)\text{d}V_{g},
\end{array}$$
where F : [0, ∞) → [0, ∞) be C3 function such that F′ > 0 on (0, ∞), τ(ψ) is the tension field of ψ. Critical points of τF,2 are called F-biharmonic maps. In this paper, we prove a nonexistence result for F-biharmonic maps from a complete non-compact Riemannian manifold of dimension m = dimM ≥ 3 with infinite volume that admit an Euclidean type Sobolev inequality into general Riemannian manifold whose sectional curvature is bounded from above. Under these geometric assumptions we show that if the Lp-norm (p > 1) of the tension field is bounded and the m-energy of the maps is sufficiently small, then every F-biharmonic map must be harmonic. We also get a Liouville-type result under proper integral conditions which generalize the result of [Branding V., Luo Y., A nonexistence theorem for proper biharmonic maps into general Riemannian manifolds, 2018, arXiv: 1806.11441v2].

Published: November 2019

Abstract
Münchausen syndrome can be characterized by simulated illness, pathological lying and wandering from place to place (the patient typically presents to numerous hospitals). Individuals with elevated blood pressure due to non-adherence to medication have the so-called pseudo-resistant hypertension.
A 45-year-old woman was admitted to hospital on an emergency basis because of a hypertensive crisis. Despite combination antihypertensive treatment, normalization of blood pressure was not achieved and a device to produce a therapeutic arteriovenous fi stula was implanted. Aft er the procedure, a signifi cant increase in pulmonary artery pressure was observed and closure of the fistula was performed by implantation of the stent graft . The suspicion was raised that the patient had not been taking her prescribed medications. Therefore, blood samples were taken and the serum was analyzed for presence of the prescribed drugs (atorvastatin, bisoprolol, chlorthalidone, clonidine, doxazosin, furosemide, nitrendipine, oxazepam and valsartan). The results confirmed suspected failure of the patient to take the prescribed medications.
Münchausen syndrome is usually first suspected when inexplicable laboratory test results are noted. To our knowledge, this is the first reported case of Münchausen syndrome with pseudo-resistant hypertension leading to the implantation of a device to produce a therapeutic arteriovenous fi stula.

Abstract
Cigarette smoking is known to induce serious lung diseases, but there is not an effective method to solve this problem. The present study investigated vitamin D3 on over-expression of CXCR3 and CXCL10 in mice induced by cigarette smoking. A pulmonary airway model was designed, and morphological assessment of emphysema, IL-4, IFN-γ and CXCL10 concentration in bronchoalveolar lavage fluids, expression of CXCR3 and CXCL10 were detected. Emphysema of the mice only exposed to cigarette smoke was significant, and concentration of IL-4, IFN-γ and CXCL10 was also increased. In addition, CXCR3 and CXCL10 were over-expressed. The degree of emphysema, concentration of IL-4, IFN-γ and CXCL10, and expression of CXCR3 and CXCL10 in mice administrated with low dose vitamin D3 were similar to the normally treated mice. Low dose of vitamin D3 can effectively protect the lung from the damage induced by cigarette smoke.

AbstractBackgroundIn peritoneal surface malignancy (PSM), in spite of optimal cytoreductive surgery (CRS), majority of recurrences that occur are intraperitoneal. In patients with PSM, studies employing fluorescent imaging and microscopic examination have shown normal looking peritoneum may harbor active disease. This study was done to assess the recurrence pattern, oncological outcomes, and morbidity and mortality of the extent of peritonectomy in patients who underwent total parietal peritonectomy (TPP) or involved field peritonectomy (IFP) as a part of the procedure during CRS and hyperthermic intraperitoneal chemotherapy (HIPEC).MethodsThis was a retrospective analysis of prospectively collected data, from February 2013 to December 2017. A total of 163 patients with PSM underwent TPP or IFP with CRS plus HIPEC. Their oncological outcomes, recurrence pattern, postoperative morbidity and mortality were analyzed.ResultsOf the 163 cases, the primary organs of origin were ovary, colorectal, appendicular pseudomyxoma, stomach, mesothelioma and others (67.4%, 16.5%, 6.1%, 4.9%, 2% and 2%), respectively. TPP was performed in 70 patients and IFP in 93 patients. TPP group had higher mean PCI (16 vs. 14), longer duration of surgery (11 vs. 9 h), and more blood loss (1,243 vs. 675 mL). Overall G3–G4 morbidity was comparable in both groups (42.8% vs. 33.3%) as was mortality (5.7% vs. 4.4%). Kaplan–Meier analysis showed that with a median follow-up of 45 months, TPP group had a recurrence-free survival (RFS) of 26 months and overall survival (OS) was yet to be achieved, whereas the IFP group had a RFS and OS of 21 and 43 months, respectively.ConclusionsPerforming TPP reduces the chance of missing the microscopic disease, therefore can minimize local recurrence, and better oncological outcomes. TPP can be performed with acceptable morbidity and mortality, at the cost of increased duration of surgery and higher blood loss.
Diachronic development of gender in city names in Spanish
Authors: Caro Reina Javier , Nowak Jessica 
Published: November 2019

AbstractThis paper examines the gender assignment rules that apply to city names in the history of Spanish, relying for the first time on extensive corpus-based material. The empirical data show that gender assignment changed from a referential principle that consistently assigned city names to the feminine (due to the feminine basic level noun for ‘city’) to a phonologically driven assignment rule, with city names ending in-agenerally being assigned to the feminine (e.g.Barcelona) and those ending in-oor-C to the masculine (e.g.Toledo,Madrid). However, the overall picture is much more complicated than previously suggested in the literature since there is still a high degree of gender variation in Modern Spanish. The use of the feminine is still possible in city names ending in-oor-C. Interestingly, the change from referential to phonological gender assignment occurs first within the NP (mainly with quantifiers such astod- o/-a‘all-m/-f’). It is in this morphosyntactic context that city names with final-amost commonly shift from the feminine to the masculine gender. This case of “evasive gender” will be discussed from a typological perspective.
Blasphemy and persecution: Positioning in an inter-religious discussion

Published: November 2019

AbstractIn May 2017, Basuki Tjahaja Purnama, popularly known as Ahok, the former Christian governor of Jakarta, Indonesia, was found guilty of blasphemy and sentenced to two years in prison. Although he was released in January 2019, his trial and the various reactions it elicited continue to highlight the very sensitive and complex issues surrounding the notion and enforcement of blasphemy and how different communities talk about it. This article focuses on a discussion about the trial between an Indonesian Muslim in favor of the blasphemy charge and an Indonesian Christian opposed to it. Using positioning analysis, it investigates how their conversation in English at a University in Japan exhibited an occasioned, fluid, developing range of evaluative language, both in terms of how they talked about themselves and others. The analysis demonstrates the complex interplay and consistent tension that is often present in inter-religious dialogue, and tracks how a wide array of discourse and contextual factors relate to developing positions, storylines, expressions of social power, and strategies for conflict management. We conclude by highlighting the inherent complexity of the dynamics of such interaction and how it can lead to greater convergence and/or tension, while emphasizing the potential benefits of face-to-face conversations around issues of possible conflict.
Paul Silas Peterson: Romano Guardini in the Weimar Republic and in National Socialist Germany: With a brief look into the National Socialist correspondences on Guardini in the early 1940s
Authors: Peterson Paul Silas 
Published: November 2019

Abstract
Romano Guardini was one of the most important intellectuals of German Catholicism in the twentieth century. He influenced nearly an entire generation of German Catholic theologians and was the leading figure of the German Catholic youth movement as it grew exponentially in the 1920s. Yet there are many open questions about his early intellectual development and his academic contribution to religious, cultural, social and political questions in the Weimar Republic and in National Socialist Germany. This article draws upon Guardini’s publications, the secondary literature on Guardini and on some archival material, seeking to outline his early development and his engagement with the ideological context following World War I and in National Socialist Germany. Here Guardini’s criticisms of the modern age are presented. Besides this many other issues are addressed, such as his criticism of the women’s movement, his understanding of the youth movement, reception of Carl Schmitt, views of race, interpretation of the controversial Volk-concept, contribution to a Jewish journal in 1933, and his basic positions on the issues of obedience, order and authority. While Guardini was viewed critically by some National Socialists in the Third Reich, the administrative correspondences on him in the 1940s actually show that there was an internal debate about him among the National Socialist officials. This involved different figures, including a diplomat who came to Guardini’s defense. The internal disagreements were made more complicated because Guardini’s brothers were apparently members of the Fascist Party in Italy at this time.
Corporate governance, accounting transparency and stock exchange sizes in Germany, Japan and «Anglo-Saxon» economies, 1870–1950
Authors: Hannah Leslie 
Published: November 2019

Abstract
Modern discussions of corporate governance have focused on convergence of «varieties of capitalism», particularly the recent «Americanisation» of laws and voluntary codes in Germany, Japan, and other civil law countries. However German and Japanese legal and business historians have suggested that corporate governance, accounting transparency or other favourable factors in their countries were historically a match for – or even superior to – those in the US. An alleged consequence was deeper penetration by the Berlin and Tokyo stock exchanges of their domestic economies than of the US by the New York Stock Exchange (NYSE), using measures such as market capitalization/GDP ratios. This paper reviews the classic Rajan and Zingales data on the sizes of stock exchanges. It concludes that the evidence for Japanese historical precocity relative to the US, after the necessary allowance is made for regional stock exchanges and corporate bond finance, stands up better to this closer examination than that for Germany.
Many financial historians now agree that stock exchange development was not historically determined by legal origins («Anglo-Saxon» common vs Euro-Japanese civil law), though today it appears to be driven by legal rules protecting shareholders and/or bondholders and limiting directorial autocracy and information asymmetry. However, both today and historically in some cultures private order rules (voluntary codes, bourse listing requirements, bankers as trusted intermediaries, block-holder monitoring, etc) offered substitute protections, or at least complemented protective laws. This paper reviews the plausibility of these determinants of historical stock exchange sizes – and others that have been neglected – in Japan, Germany, and elsewhere, before 1950.
A PROTOFICÇÃO CIENTÍFICA BRASILEIRA E SUA HIBRIDIZAÇÃO ATRAVÉS DO FANTÁSTICO: UMA ANÁLISE DO CONTO “A SOMBRA” DE COELHO NETO
Authors: Sousa Thalita Ruth , Santos Naiara Sales Araújo 
Published: November 2019

A Protoficção Científica compreende obras produzidas antes da formação da Ficção Científica, mas que possuem fundamentos ligados ao desenvolvimento tecno científico. Caracterizada pelo hibridismo, a ProtoFC, por vezes, apresenta afinidades com outros gêneros. Este é o caso do conto A sombra (1927) do escritor Coelho Neto, que tem proximidades com o Fantástico. Nele, o personagem Avellar, um bacteriologista, mata a esposa Celúta através de um experimento com injeções de vírus e bacilos. Após isto, ele é perseguido por uma sombra até que confessa o assassinato. Observa-se que a experiência científica provoca o medo do desconhecido, culminando num evento sobrenatural, rompendo com a realidade. A ciência, portanto, mostra-se falível e incapaz de fornecer explicações para tudo. Considerando as mudanças no cenário nacional devido ao progresso científico apregoado no início do século XX, objetiva-se analisar, por meio de pesquisa bibliográfica, a representação da ciência no conto A sombra (1927) e sua relação com a sociedade da época. A presente pesquisa visa também averiguar como a hibridização se constitui através do Fantástico na narrativa. Para tanto, são utilizados os apontamentos de Mary DelPriore (2014), Raul Fiker (1985), Isaac Asimov (1979) e David Roas (2018), entre outros. Palavras chave: Protoficção Científica; fantástico; Coelho Neto.
Discours médiés par ordinateur et stratégies d’adresse
Authors: Havu Eva 
Published: November 2019

Generally, interviewers and interviewees address each other by the “traditional” deferential pronoun vous in French oral and written media, whereas in specialized magazines and television programs, tu often seems to be the usual address pronoun (cf. Williams & van Compernolle 2009; Coveney 2010). However, Internet forums discussing the use of forms of address (consulted in 2015), point out the prevalence of very traditional opinions, contrasting with the above-mentioned observation. In general, less attention has been paid to nominal forms of address.
This paper examines the use of pronominal and nominal forms of address in blogs on politics and in forums discussing current political events, that is in two types of Computer-Mediated Communication where the writers lack information about their interlocutor (age, social status, profession…). It shows to what extent their choice is dependent on the type of medium and on the context as well as on the relation between the interlocutors (conflictual, neutral…) and how nominal forms of address accentuate certain aspects of interpersonal relations. It also points out that the generalization of tu in special contexts does not reflect a drastic change in the use of forms of address in general.
L'autocitation dans la théorie scandinave de la polyphonie linguistique (ScaPoLine)
Authors: Manga Christian 
Published: November 2019

The present work focuses on the discursive phenomenon of self-quotation, that we define with Rosier (2008, 118) as « the staging of one's own speech or opinion in the service of a specific argument on the mode of recall (I told you that) or performative mode (I tell you that).» Our aim is to study the particular functioning of self-quotation within the Scandinavian theory of linguistic polyphony (ScaPoLine). Depending on whether the self-quotation is in the mode of an earlier saying or a present one, we will postulate a typology of speakers: homogeneous speaker (self-quotation in the present) and heterogeneous speaker (self-quotation in the past).
Le rapport entre changement et acquisition illustré au moyen du système du futur
Authors: Lindschouw Jan , Löbl Stephanie Kim 
Published: November 2019

The future tense system in French has undergone important reorganisations during the period from Middle to Modern French. During this period the synthetic future (parlera ‘will talk’) has changed from a system in which it expressed two semantic values to a system in which it expresses one single value. At the same time, the analytic future (va parler ‘is going to talk’) has undergone the opposite evolution having thus expanded its domain of use and covers nowadays a part of the domain formerly belonging to the synthetic future.
At the same time, it is interesting to observe a parallel between the change of the grammatical forms of the future tenses and their acquisition by learners of FLE. Indeed, the learners seem to master the future tense form in progression (i.e. the analytic future) earlier than the future tense form in the process of reduction (i.e. the synthetic future). Furthermore, they tend to use the analytic future as their default form.
In this contribution, three major factors are proposed as an explanation of this order of acquisition: 1. The frequency of the future tense forms in the oral and written input that the students receive in and outside the classroom; 2. The transfer from the students’ native language (Danish) which only possesses an analytical future form (will + infinitive); 3. The relation between the form and the function of the two future tenses.
Finally, it is discussed to which extent the linguistic forms in the process of reduction should be taught.

Abstract

Background
Delirium, a neuropsychiatric syndrome that occurs throughout medical illness trajectories, is frequently misdiagnosed. The Memorial Delirium Assessment Scale (MDAS) is a commonly used tool in palliative care (PC) settings. Our objective was to establish and validate the Memorial Delirium Assessment Scale-Thai version (MDAS-T) in PC patients.

Materials and Methods
The MDAS was translated into Thai. Content validity, inter-rater reliability, and internal consistency were explored. The construct validity of the MDAS-T was analyzed using exploratory factor analysis. Instrument testing of the MDAS-T, the Thai version of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU-T), and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition as the gold standard was performed. The receiver operating characteristic (ROC) curve was used to determine the optimal cutoff score. The duration of each assessment was recorded.

Results
The study enrolled 194 patients. The content validity index was 0.97. The intraclass correlation coefficient and Cronbach's α coefficient were 0.98 and 0.96, respectively. A principal component analysis indicated a homogeneous, one-factor structure. The area under the ROC curve was 0.96 (95% confidence interval [CI], 0.93–0.99). The best combination of sensitivity and specificity (95% CI) of the MDAS-T were 0.92 (0.85–0.96) and 0.90 (0.82–0.94), respectively, with a cutoff score of 9, whereas the CAM-ICU-T yielded 0.58 (0.48–0.67) and 0.98 (0.93–0.99), respectively. The median MDAS-T assessment time was 5 minutes.

Conclusion
This study established and validated the MDAS-T as a good and feasible tool for delirium screening and severity rating in PC settings.
Linear Matrix Inequalities in Stability Problems: Retrospective and Theoretical Aspects
Authors: Kamenetskiy V. A. 
Published: November 2019

Some aspects of the development of the theory of linear matrix inequalities are considered. A number of results obtained at the initial stage of the development of this theory, both in the development of numerical methods and in obtaining analytical conditions for their solvability, are highlighted. The main attention is focused on the system of linear matrix inequalities arising in solving the absolute stabi lity problem. E. S. Pyatnitskiy and his followers showed that the solvability of this system is a criterion for the existence of a quadratic Lyapunov function and a sufficient condition for absolute stability. The prerequisites leading to this result are considered here. The use of the considered system of inequalities for studying the stability of hybrid systems described by differential inclusions and switching systems is shown. An analysis is given of citing some works of Pyatnitskiy’s school on the theory of stability and the theory of systems of linear matrix inequalities, from which the relevance of the results of these works at the present time follows.In developing numerical methods, it was first shown in the work of Pyatnitskiy and Skorodinskiy that the solvability problem for a system of linear matrix inequalities reduces to a convex programming problem. An interesting gradient algorithm for finding solutions to such a system is also presented. In analyzing analytical conditions of solvability, an unsolvability criterion for the system of our interest obtained by Kamenetskiy and Pyatnitskiy is noted. In modern terms, this result can be considered as a description of an admissible set in the dual semidefinite programming problem. A similar result is given in the famous book by S. Boyd et al. The paper shows that the result of Boyd et al. is a simple corollary of the unsolvability criterion. Here the unsolvability criterion is generalized and refined.
