Visual Query Languages
study ways to help users compose queries with visual metaphors.
Information Visualization
studies automatic visualization techniques to help users understand and analyze data.
Query Management
focuses on ways to help users manage and re-use existing queries. We observe that there is a related research question across those three topics which has not received much attention, namely that of
Query Visualization: How to visually represent a query to help users quickly understand its intent?
Here we argue that the involved challenges are still markedly different from those of the other three, that a solution can considerably improve the usability of DBMSs, and that the topic is thus worthy of attention. We envision, that in a few years, there will be free, modular, and lightweight tools available that allow users to visualize and interpret their queries.

Authors: Akaraborworn Osaree , Sangthong Burapat , Thongkhao Komet , Chainiramol Pratthana , Kaewsaengrueang Khanitta
Published: June 2020

Background

Trauma is a major cause of death in young adults. The mortality rate is one of the key performance indices of trauma centers.

Objective

To demonstrate a mortality rate, cause of death, and cause of nonpreventable death in a level-1 trauma center in Thailand.

Methods

There was a retrospective study of the death cases from a trauma registry. The number of trauma deaths during the study period was collected to identify the death rate. The causes of death and a death analysis were obtained from the morbidity and mortality.

Results

The death rate was 6.6%. The most common cause of overall death was head injury, and exsanguination was the most common cause of death in the first 24 h. The preventable death rate was 2%, and the most common cause of preventable death was exsanguination.

Conclusions

The mortality rate of trauma patients in Thailand was not higher than that in other countries. The majority of deaths were caused from head injury. Therefore, improvement in injury prevention is needed to decrease the number of deaths.

Authors: Ramalingam Ashwin Kumar , Selvi Smiline Girija Aseervatham , Jayaseelan Vijayashree Priyadharsini
Published: June 2020

Background

Complications in periodontitis and other systemic infections related to Porphyromonas gingivalis poses a serious impediment in the treatment process. This leads to the search of novel target proteins to develop newer drugs against P. gingivalis. Prolyl tripeptidyl peptidase (ptp-A) seem to be a vital protein in P. gingivalis virulence and can be a good target for the novel natural bioactive compounds.

Objectives

To explore the inhibitory potential of Rosmarinus officinalis biocompounds against the ptp-A of P. gingivalis.

Methods

Three-dimensional structure of ptp-A was retrieved from the Protein Data Bank with further optimization of both the protein and ligands. In silico inhibitory potential of the selected ligands against ptp-A was done by AutoDock 2.0 and was visualized with Biovia discovery studio visualizing tool with the assessment of the molecular properties of the ligands against ptp-A by molinspiration calculations and drug likeliness.

Results

High ptp-A inhibitory effect was observed using rosmarinic acid and luteolin with a bonding energy of −9.81 kcal/mol with 10 hydrogen bond interactions and −9.99 kcal/mol with 7 hydrogen bond interactions, respectively. Carnosic acid and p-coumaric acid showed a binding energy of −7.14 kcal/mol and −6.34 kcal/mol, respectively, with 5 hydrogen bond interactions. Molinspiration assessments showed R. officinalis compounds as the best drug candidates with the topological polar surface area scores <140 Å toward the best oral bioavailability.

Conclusion

The carnosic acid, rosmarinic acid, p-coumaric acid, and luteolin from R. officinalis seem to possess a promising inhibitory effect against ptp-A of Candida albicans suggesting ptp-A as the best target to combat P. gingivalis with further in vivo validation.
Zwischen Ost und West: Zur Druckgeschichte von Schimon Günzburgs jiddischer Brauchsammlung
Authors: Raspe Lucia
Published: June 2020

Shimʻon Günzburg’s Yiddish collection of customs, first brought to press in Venice in 1589 and reprinted dozens of times over the following centuries, is often considered a mere translation of the Hebrew Minhagim put together by Ayzik Tyrnau in the 1420s. Another claim often made about the book is that, although it was first printed in Venice, it was intended less for the Italian book market than for export. This article sets out to test these assumptions by examining Günzburg’s compilation from the perspective of minhag, or prayer rite. Drawing on Yiddish manuscripts preserved from sixteenth-century Italy, as well as early printed editions overlooked by scholars, it argues that Günzburg’s Minhogim are, in fact, more Italian than has been recognized. It also points up their potential for a comparative history of Ashkenazic book culture across the political and linguistic borders of Europe.
Un fantôme historique : «l’autre Theophane»
Authors: Yannopoulos Panayotis
Published: June 2020

At the beginning of the 9th c. George Syncellus began to write a universal chronicle, the second part of which was completed by the monk Theophanes. According to Byzantine tradition this monk was Theophanes the Confessor. But 10th-century sources note that this Theophanes was the grandfather or greatuncle of the emperor Constantine VII, which is historically impossible. This prompted P. Speck to invent “another Theophanes”, who lived during the second half of the 9th c. and was the editor of the Chronicle of Theophanes. The hypothesis turns out to be unfounded and untenable. Also untenable and unrelated to the sources is the hypothesis of C. Zuckerman that the author of the Chronicle is another Theophanes who lived at the same time as the Confessor. This study, after an analysis of sources, proves in both cases that they are historical phantoms.

Published: June 2020

Barbary fig called prickly pear is a plant belonging to family Cactaceae growing under hard climate conditions. A spiny variety of prickly pear named “Drbana” (Opuntia megacantha) and two non-spiny varieties named “Akria” and “Mlez” (Opuntia ficus-indica) growing in the Rhamna region (Morocco) were studied in terms of physicochemical characteristics. The physicochemical characterization (humidity, water activity, pH, total titratable acidity, Brix, and ash content) and the biochemical characterization (total carotenoid content, betalain content, total polyphenolic content, and ascorbic acid content) of the fruit pulp of prickly pear were performed according to the previously reported methods. The finding of physicochemical characterization of all studied varieties showed that the fruit pulp also contained an interesting bioactive compound classes in humidity, water activity, pH, total titratable acidity, Brix, and ash content. Regarding the biochemical characterization, the obtained finding showed the fruit pulp also contained an interesting bioactive compound classes particularly the total betalains, polyphenols, carotenoids, and ascorbic acids. Based on the obtained results in the current research work, we can affirm that the fruits of all studied varieties meet the requirement for being exploited in food, cosmetic, and pharmaceutical industries.
Comparative studies of two vegetal extracts from Stokesia laevis and Geranium pratense: polyphenol profile, cytotoxic effect and antiproliferative activity
Authors: Pirvu Lucia , Neagu Georgeta , Terchescu Iulian , Albu Bujor , Stefaniu Amalia
Published: June 2020

In this study, two ethanolic extracts, fromStokesia aster(Slae26) andGeranium pratense(Gpre36) respectively, were evaluated in order to assess the cytotoxic activity and potential antiproliferative activity upon the nontumorigenic human epithelial cell line derived from the mammary gland (MCF-12A) and the human breast tumor cell line (BT-20). The selection of the plant species was done on the basis of their chemical composition, specifically combinations of luteolin derivatives with caffeic and gallic acid derivatives. Therefore, theS. laevisethanolic extract proved its capacity to inhibit the viability of both normal and tumor breast cell lines (i.e., up to 90% cell viability inhibition, IC50= 42 µg/mL). On the contrary, theG. pratenseethanolic extract proved weak stimulatory effects on the viability of the two human breast cell lines studied. The obtained results were discussed in the contexts of computational studies and drug-likeness bioactivity of seven common luteolin derivatives: luteolin, luteolin-7-O-glucoside/cynaroside, luteolin-5-O-glucoside/galuteolin, luteolin-6-C-glucoside/isoorientin, luteolin-8-C-glucoside/orientin, luteolin-3′,4′-di-O-glucoside and luteolin-7,3′-di-O-glucoside. Computational studies have revealed that the hydrophilic behavior of luteolin derivatives (log Pvalues) does not follow other tested parameters (e.g., polar surface area values), possibly explaining different efficacy concerning the biological propertiesin vitro. These predictions could be a starting point for studies on the biochemical mechanism by which luteolin derivatives induce biological effects.
Numerical Modeling of Phenol Adsorption on Granular Activated Carbon Fixed Bed: Comparison of Two Numerical Methods to Solve the Advection-dispersion Equation
Authors: Kolli Mounira , Semra Safia , Benmahdi Fatiha , Bouhelassa Mohamed , Sardin Michel
Published: June 2020

This paper presents a comparison between some numerical methods and techniques for solving the nonlinear advection-dispersion equation, which may be used to describe the adsorption of phenol into a granular activated carbon fixed bed under local equilibrium conditions. The adsorption is described by the Langmuir isotherm, which makes the advection-dispersion equation nonlinear. This equation is solved successively by using the approximation and linearization techniques. For each technique, two types of numerical algorithms are used. Concerning the first one, the Implicit and the Runge Kutta schemes are used. As for the second one, the Modified Picard iteration and the Newton Raphson scheme are applied. Simulation results have been compared to each other and to the experimental data as well. Both of the Implicit and the Runge Kutta algorithms have led to superimposed simulated breakthrough curves. Both of the modified Picard and Newton Raphson schemes have given identical results too. However, comparing to the experimental data, the obtained solution, using the approximation technique, has underestimated the retardation of solute and failed in fitting the experimental breakthrough. The Obtained solution, using the linearization technique, has correctly fitted the experimental results under all the conditions of: feed flow rate, activated carbon bed height and the inlet phenol concentration.

Estimation of Sport Facilities by Means of Technical-Economic Indicator
Authors: Hanak Tomas , Hrstka Lukas , Tuscher Martin , Biolek Vojtech
Published: June 2020

This paper is concerned with early cost estimation of sport facilities. Sufficiently precise cost estimation is essential for investors in the pre-investment stage where they decide on whether to pursue an investment and choose a suitable technical solution for the development of the project. Through a detailed analysis of the technical and economic documentation pertaining to seven sport facilities projects assembled using concrete prefabricated beam parts, as well as evaluation of the data thus obtained, three types of technical-economic indicators were set in relation to the enclosed building area, the number of spectator seats and the sports playing area. The results achieved indicate that evaluation of relations between these three indicators could contribute to a more effective use of investment funding on the part of the investor. Other conclusions include the finding that available indicators published by private companies active in the area of construction budgeting are not sufficiently accurate for the purposes of investment decision-making; specifically, these indicators greatly overestimate the costs of sport facilities, which can potentially lead to these projects being rejected. This contribution brings know-how for a more accurate early cost estimation of sport facilities in the Czech Republic which can, thanks to a generally applicable methodology, be used in other countries as well.
From constructions to functions and back: Contrastive negation in English and Finnish
Authors: Silvennoinen Olli O.
Published: June 2020

This is a comparative investigation of contrastive negation in English and Finnish, i. e. combinations of a negated and an affirmed part construed as alternatives to one another. In both languages, there are several constructions that express contrastive negation, but their division of labour remains unclear. The aims of the paper are two-fold: first, to see what constructional strategies are available for contrastive negation in the two languages and, second, to see how the strategies are motivated by its interactional functions. In English, contrastive negation may be expressed by using the adversative conjunction but correctively (e. g. It’s not the bikers but the other vehicle on the road), whereas standard Finnish has a specialised corrective conjunction vaan alongside the adversative mutta. Moreover, many constructions can express contrastive negation, including ones without a conjunction (e. g. It’s not the bikers, it’s the other vehicle on the road). An analysis of conversational data shows that English favours constructions without conjunctions, while in Finnish constructions both with and without conjunctions are frequent. The uses of contrastive negation are divided into reactive and non-reactive. The pragmatic functions largely explain the usage patterns, and these in turn can explain the cross-linguistic regularities of corrective conjunctions.
The syntax and semantics of Modern Standard Arabic resumptivetough-constructions
Authors: Tayalati Fayssal , Danckaert Lieven
Published: June 2020

This paper is concerned with a hitherto undiscussed type oftough-construction in Modern Standard Arabic (MSA). Our starting point is the observation that thetough-adjective in this construction invariably displays nominative masculine singular morphology, a pattern of ‘default’ agreement which does not seem to occur elsewhere in the grammar of MSA. At a semantic level, the relevant adjective is argued to form a complex predicate with a deverbal nominalization that acts as its complement: together, these two elements indirectly modify the subject noun phrase. To explain the default agreement pattern, we propose that MSAtough-constructions involve two distinct subjects, viz. a phonologically null expletive subject which controls agreement on thetough-adjective, and a Broad Subject which acts as the semantic subject of the whole construction. We show that there is independent evidence for the existence of both null expletives and Broad Subjects in MSA.
A quasistatic frictional contact problem for viscoelastic materials with long memory
Authors: Kasri Abderrezak , Touzaline Arezki
Published: June 2020

The aim of this paper is to study a quasistatic frictional contact problem for viscoelastic materials with long-term memory.
The contact boundary conditions are governed by Tresca’s law, involving a slip dependent coefficient of friction.
We focus our attention on the weak solvability of the problem within the framework of variational inequalities.
The existence of a solution is obtained under a smallness assumption on a normal stress prescribed on the contact surface and on the coefficient of friction.
The proof is based on a time discretization method, compactness and lower semicontinuity arguments.
Survey of school nurses’ experiences of providing counselling on sexual orientation to high school students in Japan
Authors: Terao Ryohei , Kaneko Noriyo
Published: June 2020

Objective

To ascertain the prevalence and correlated factors of providing consultation on sexual orientation and the characteristics of school nurses in high schools in Japan.

Methods

Participants were school nurses working in high schools in Aichi prefecture. Items investigated included background, experiences in providing counselling on sexual orientation, the availability of materials and resources for students, and learning experiences concerning how to handle sexual orientation concerns. We divided the respondents into two groups: one group who have provided counselling on sexual orientation before and one group with no such experience. Chi square tests were utilized to compare the responses between groups.

Results

Among the respondents, 38.9% (n = 140) had previous experience of providing counselling to students on sexual orientation. The group with experience of providing counselling is more likely to have 10–29 years of experience, to work at a senior high school, to be informed on notifications from the Ministry of Education, to have experience of learning how to provide counselling on sexual orientation, and to be aware of effective resources.

Conclusion

In Japan, it is expected that the support needs related to LGBTI will become more obvious in the future and efforts to create an environment in which it is easy for young people to consult with school nurses or other support figures are necessary.

In adjusted multinomial logistic regression, living away from home, perceived overweight, inadequate fruit and vegetable intake, physical inactivity, short sleep, long sleep, depression and in a physical fight were associated with infrequent and/or frequent skipping breakfast.

Conclusion

Almost two in five students skipped breakfast, and several factors were identified that can be targeted in intervention programmes.
The importance of Internet systematic search for legal translations
Authors: Giampieri Patrizia
Published: June 2020

The web is a vast and disorganised language resource which is often accessed too naively or superficially by students or inexperienced translators. In this paper, bachelor's students enrolled in a course in translation studies are challenged to translate an extract of a legal document. To complete their translation task, they consulted the language resources they felt comfortable with. Some of them asked for advice to external experts. This helped make the translation task real-life. Despite the language tools used, the students' shortcomings and mistranslations were several. In particular, formulaic expressions were neglected and too many literal or “fanciful” translation candidates were proposed. Afterwards, the students took part in a 2-h lesson where they understood how to consult the web effectively to find reliable information. This paper will highlight that a systematic approach to Google search is necessary in order to deliver high-quality translation work. In particular, advanced search must be performed, together with an accurate consultation of legal documents and of authoritative sources, such as experts' forums or sites.

Conditioned medium from the human umbilical cord-mesenchymal stem cells stimulate the proliferation of human keratinocytes
Authors: Sriramulu Sushmitha , Banerjee Antara , Jothimani Ganesan , Pathak Surajit
Published: June 2020

Objectives

Wound healing is a complex process with a sequence of restoring and inhibition events such as cell proliferation, differentiation, migration as well as adhesion. Mesenchymal stem cells (MSC) derived conditioned medium (CM) has potent therapeutic functions and promotes cell proliferation, anti-oxidant, immunosuppressive, and anti-apoptotic effects. The main aim of this research is to study the role of human umbilical cord-mesenchymal stem cells (UC-MSCs) derived CM in stimulating the proliferation of human keratinocytes (HaCaT).

Methods

Firstly, MSC were isolated from human umbilical cords (UC) and the cells were then cultured in proliferative medium. We prepared and collected the CM after 72 h. Morphological changes were observed after the treatment of HaCaT cells with CM. To validate the findings, proliferation rate, clonal efficiency and also gene expression studies were performed.

Results

Increased proliferation rate was observed and confirmed with the expression of Proliferating Cell Nuclear Antigen (PCNA) after treatment with HaCaT cells. Cell-cell strap formation was also observed when HaCaT cells were treated with CM for a period of 5–6 days which was confirmed by the increased expression of Collagen Type 1 Alpha 1 chain (Col1A1).

Conclusions

Our results from present study depicts that the secretory components in the CM might play a significant role by interacting with keratinocytes to promote proliferation and migration. Thus, the CM stimulates cellular proliferation, epithelialization and migration of skin cells which might be the future promising application in wound healing.
Cytokine and inflammatory mediators are associated with cytotoxic, anti-inflammatory and apoptotic activity of honeybee venom
Authors: Salama Mohamed A. , Younis Mohamed A. , Talaat Roba M.
Published: June 2020

Objective

The present study aimed to evaluate cytotoxic, apoptotic, and anti-inflammatory properties of bee venom (BV) as well as changes in cytokine secretion levels and nitric oxide (NO) production using three different cancer cell lines [liver (Hep-G2), breast (MCF-7), and cervical (HPV-18 infected HeLa cells)] and two normal cells (splenocytes and macrophages (MQ).

Methods

Cytotoxic activity of BV against tumor cell lines and normal splenocytes/MQ was tested by MTT assay. By ELISA (ELISA); Tumor necrosis factor (TNF-α), Interleukine (IL-10) and interferon (IFN-γ) were measured. Caspase three expressions was evaluated using reverse transcription-polymerase chain reaction (RT-PCR). Nitric oxide (NO) was estimated using a colorimetric assay.

Results

BV has a significant cytotoxic effect on all cell lines in a dose- and time-dependent manner; none of them was toxic for normal cells. Treating Hep-G2 cells with BV showed a reduction in IL-10, elevation in TNF-α with no change in IFN-γ level. MCF-7 cells have low IL-10 and TNF-α and high IFN-γ production level. Elevation of IL-10 and IFN-γ coincides with a reduction in TNF-α level was demonstrated in HeLa cells. The expression of Caspase three was dramatically increased with elevation in BV concentration in all tested cancer cell lines. A gradual decrease in NO production by MQ with increasing BV dose was observed.

Conclusion

Taken together, our results stressed on the importance of BV as a potent anti-tumor agent against various types of cancers (Liver, Breast, and Cervix). Further steps towards the use of BV for pharmacological purposes must be done.
Jenseits des Dualismus zwischen tierischer Natur und geistiger Natur: Kants Mensch „in zwiefacher Qualität“ und Schillers „ganzer Mensch“
Authors: Falduto Antonino
Published: June 2020

In my contribution, I discuss the important role of moral anthropological questions in the development of Schiller’s theoretical thought. I underline the fact that Schiller’s philosophical questions in Jena are much closer to those he confronted in Stuttgart – much closer than is considered to be the case in contemporary Schiller scholarship. I show how this continuity becomes evident when we take into consideration the moral anthropological topics that continued to interest Schiller throughout his life. To ground my argument, I show that the concept of the“whole human being” (i. e. the concept of a human considered in its entirety, as both sensible and rational) constitutes the continuous characteristic of Schiller’s philosophical considerations.

Subsidia dominationi:The Early Careers of Tiberius Claudius Nero and Nero Claudius Drusus Revisited
Authors: Vervaet Frederik Juliaan
Published: June 2020

Whereas many aspects of the Augustan age continue to enjoy ongoing or renewed interest, the early careers of Tiberius Claudius Nero (born 16 November 42 BCE) and Nero Claudius Drusus (March/April 38 BCE), Livia’s sons from her marriage to Ti. Claudius Nero (pr.42), have not been subject to much discussion or controversy of late. On the one hand, this could, perhaps, be explained in that they were quite young during the formative stages of the so-called Augustan monarchy, the critical settlements being those of 27, 23 and 19 BCE, the eye-catchers par excellence in the political history of the early Augustan era. On the other hand, Livia’s sons only really emerge into the spotlight of both ancient sources and modern scholarship after the untimely passing of M. Vipsanius Agrippa in 12 BCE. This paper aims at revisiting the evidence for Tiberius’ and Drusus’ careers in the decade or so before the latter’s premature death in Germany in 9 BCE, the period preceding the rapid rise (and demise) of Gaius and Lucius Caesar. There are, indeed, strong indications that Livia’s sons played a far more important part than has hitherto been recognized, both in terms of their official position and their role in assisting Augustus with one of his most important political objectives, namely the imperial monopolization of the public triumph.

Published: June 2020

A predator-prey model interaction under fluctuating water level with non-selective harvesting is proposed and studied in this paper. Sufficient conditions for the permanence of two populations and the extinction of predator population are provided. The non-negative equilibrium points are given, and their stability is studied by using the Jacobian matrix. By constructing a suitable Lyapunov function, sufficient conditions that ensure the global stability of the positive equilibrium are obtained. The bionomic equilibrium and the optimal harvesting policy are also presented. Numerical simulations are carried out to show the feasibility of the main results.

Published: June 2020

Melanoma is one of the most highly metastatic, aggressive and fatal malignant tumors in skin cancer. This study employs bioinformatics to identify key microRNAs and target genes (TGs) of plasma extracellular vesicles (pEVs) and their diagnostic and prognostic significance in melanoma. The gene expression microarray dataset (GSE100508) was downloaded from the Gene Expression Omnibus database. Differential analysis of miRNAs in pEVs was performed to compare melanoma samples and healthy samples. Then, TGs of the differential miRNAs (DE-miRNAs) in melanoma were selected, and differential genes were analyzed by bioinformatics (including Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment, protein–protein interaction network and prognostic analysis). A total of 55 DE-miRNAs were found, and 3,083 and 1,351 candidate TGs were diagnostically correlated with the top ten upregulated DE-miRNAs and all downregulated DE-miRNAs, respectively. Prognostic analysis results showed that high expression levels of hsa-miR-550a-3p, CDK2 and POLR2A and low expression levels of hsa-miR-150-5p in melanoma patients were associated with significantly reduced overall survival. In conclusion, bioinformatics analysis identified key miRNAs and TGs in pEVs of melanoma, which may represent potential biomarkers for the early diagnosis and treatment of this cancer.

Published: June 2020

Wide gamut and angle-insensitive structural colors are highly desirable for many applications. Herein, a new type of lithography-free, planar bilayer nanostructures for generating structural colors is presented, which is basically composed of a deep-subwavelength, highly absorbing dielectric layer on an opaque metallic substrate. Experimental results show that a galaxy of brilliant structural colors can be generated by our structures, and which can cover ∼50% of the standard red–green–blue color space by adjusting the nanostructure dimensions. The color appearances are robust with respect to the angle of vision. Theoretical partial reflected wave analyses reveal that the structural color effect is attributed to the strong optical asymmetric Fabry–Perot-type (F–P-type) thin-film resonance interference. The versatility of the structural color properties as well as the simplicity of their fabrication processes make this bilayer structures very promising for various applications, such as security marking, information encryption, and color display, etc.
Feasibility of removal S−2from Kraft black liquor recovery cycle with synthetic adsorbents (Cu-PAC and Cu-GAC)
Authors: Mollaei Masoume , Moeinaddini Mazaher , Khorasani Nematollah , Azadfallah Mohammad , Hemmasi Amirhooman
Published: June 2020

Sulfide ions (S−2) derived from Na2S in black liquor, after the pulping process, is the source of production H2S during of black liquor recovery cycle in Kraft pulp and paper industries. Tow adsorbents (Cu-PAC, Cu-GAC) by loading Cu+2on powder activated carbon (PAC) and granular activated carbon (GAC) were synthesized to created more adsorption sites and were improved their selectivity for removing S−2from black liquor with 3 level of sulfidity (18, 20 and 22 %). The adsorbents were characterized by BET, FTIR, SEM, and EDX. Adsorption of S−2for Cu-PAC and Cu-GAC were fitted well with Freundlich and Langmuir isotherm model respectively and both of the adsorbents followed pseudo-second-order kinetic. The results of thermodynamic parameters showed the endothermic process. The removal efficiency results showed Cu-PAC has better performance than Cu-GAC. This is due to the higher specific surface area of Cu-PAC, which has led to more adsorption sites for S−2. By considering appropriate temperature conditions and direct effect of the S−2on the production of H2S during of black liquor recovery cycle, Cu-PAC will be able to prevent H2S production and odorous the black liquor recovery cycle by removing 79.89 % of the S−2.
„Denn sie wissen nicht, was sie tun“ – Irrtum und moralische Zurechnung in Peter Abaelards Ethica – scito te ipsum
Authors: Gerlach Stefan
Published: June 2020

In diesem Artikel soll Peter Abaelards (1079–1142) Moralphilosophie vorgestellt werden, wie er sie in seiner Schrift Ethica – scito te ipsum (ca. 1139) entworfen hat. Besonderheit dieser Ethik ist es, dass Abaelard ausschließlich die Absicht einer Handlung als Gegenstand der moralischen Beurteilung zulässt. Von dieser sehr fortschrittlichen Position aus stellt sich allerdings die Frage, wie nach Abaelard der Fall zu behandeln ist, bei dem jemand einem Irrtum unterliegt, wie dies der Fall bei den Peinigern Jesu zu sein scheint, um deren Vergebung Jesus nach Lk 23 bittet. Ein Vergleich mit der Irrtumslehre des modernen Strafrechts zeigt die Aktualität und Grenzen des Ansatzes Abaelards.
Die ethische Pascaline
Authors: Schmidt Jochen
Published: June 2020

Die „ethische Pascaline“ ist ein Kunstwort, gemeint ist ein Modell der Arbeit theologischer Ethik, das von mechanistischen Annahmen geleitet ist, v. a. von der Annahme, dass die praktischen Widerstände, auf die die Arbeit der Ethik stößt, keine maßgeblichen Rückwirkungen auf die Bestimmung der Aufgabe und des Wesens der theologischen Ethik haben. Im Gegenüber zu einer solchen Konzeptualisierung werden Konturen einer hermeneutischen Ethik gezeichnet. Hermeneutische Ethik legt den Fokus auf das Prozesshafte aller ethischen Arbeit, auf unabschließbare Vorgänge der Erschließung von christlicher Tradition und ethischer Übung. Hermeneutische Ethik ist keine exklusive Alternative zu analytischer, „pascalinesquer“ Ethik, wohl aber eine notwendige Supplementierung, der deutlich mehr Aufmerksamkeit zuteilwerden sollte, als es bisher der Fall ist.
English comparative correlative constructions: A usage-based account
Authors: Hoffmann Thomas , Brunner Thomas , Horsch Jakob
Published: June 2020

English Comparative Correlatives (CCs) consist of two clauses, C1 and C2:

[The more we get together,]C1[the happier we’ll be.]C2

Recently, large corpus studies based on the Corpus of Contemporary American English have unearthed various meso-constructions in English CCs using covarying–collexeme analysis. The present study tests these findings against data from the British National Corpus (BNC), aiming to replicate previous results against data from another standard variety of English (British English) and a corpus that is sampled from a wider range of registers. Over 2,000 CC tokens from the BNC were analyzed with regard to hypotactic features, filler types encountered as comparative elements, and deletion phenomena. Moreover, in contrast to earlier corpus studies (such as Hoffmann, Thomas, Jakob Horsch, and Thomas Brunner. 2019. “The more data, the better: a usage-based account of the English comparative correlative construction.” Cognitive Linguistics30(1): 1–36), the present study also investigates the frequency of the semantically related C2C1 construction (You will be the happierC2,the more we get togetherC1) that previously has been found to be considerably less frequent than its counterpart. The results of the present analysis confirm that English CCs possess more paratactic than hypotactic features and, supporting most of the findings of Hoffmann, Horsch, and Brunner (2019) provide even stronger evidence for the existence of several symmetric meso-constructions.

Dynamics between the budget deficit and the government debt in the United States: a nonlinear analysis
Authors: Ahmed Haydory Akbar
Published: June 2020

This paper empirically investigates the dynamics between budget deficit and government debt in the U.S. using two different measures of the budget deficit: the current budget deficit and cyclically-adjusted budget deficit. A threshold Vector autoregression (VAR) model is estimated to explore the dynamics in different regimes using quarterly data from 1947:Q1 to 2017:Q3. The specification test rejects a linear VAR model against the threshold VAR. When we use the current budget deficit, regime 1 resemble governments prioritize minimizing budget deficit and debt, whereas, regime 2 resemble otherwise. When we use the cyclically adjusted budget deficit, regime 1 resemble economic expansions, whereas, regime 2 resemble recessions. The impulse responses show evidence of asymmetry and counter-cyclicality. The impulse responses also indicate that an increase in the debt dictate the government’s response towards minimizing the budget deficit and tend to prioritize budget deficit less when the economy expands.
Is Josephus Among The Qumranites? Unraveling A Textual Conundrum In 1 Samuel 10:27b
Authors: Glover Daniel B.
Published: June 2020

Although Josephus’s biblical works typically reflect a dependence on the LXX, his text of Samuel presents a curious case to Hebrew Bible textual critics. One conundrum is found in 1Sam 10:27b, which includes material not found in the LXX or the MT. The presence of the same plus in 4QSama complicates the textual discussion. Some scholars take its presence in Josephus and 4QSama as evidence that the plus was omitted accidentally by the LXX and MT. While I broadly agree with their conclusions, this paper complicates their arguments and provides a more compelling reason for the omission of this material in the LXX and MT. The paper concludes by recognizing the value that the biblical text preserved in Josephus’s works brings to Hebrew Bible textual criticism.
1QSamuel–A Pre-canonical Shorter Recension of 2Samuel
Authors: Elgvin Torleif
Published: June 2020

1QSamuel preserves a shorter ending of 2Samuel. Of the eight appendices attached to 2Samuel (20:23–24:25), the scroll contained either three or five, dependent on the (reconstructed) height of the columns. The scroll definitively omits the story of the census, a post-Chronicles insertion into 2Samuel. Also 21:1–14 and 23:1–7 are texts from the Hellenistic period. A comparison of 2Sam 21:1–14 and 1Sam 22:6–23 (the killing of the priests of Nob) suggests a late date also for the latter text, a dating supported by a suggested archaeological identification for the site of Nob.
Hebrewכֶּתֶרand Greek κίταρις: Revisiting the Persian Hypothesis

A nanocomposite electrode, obtained by combining two high performance perovskite materials, such as lanthanum strontium cobalt ferrite, La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) and gadolinium doped ceria, Ce0.85Gd0.15O1.5 (GDC), were investigated as a promising cathode for moderate temperature solid oxide fuel cells (SOFCs). The synthesized material has good conductivity and catalytic performance. The purpose of this synthesis was to prepare a stable and highly performing nanocomposite cathode material. In this research work, LSCF and GDC were separately synthesized by co-precipitation and solid-state reaction method to gain a homogeneous perovskite phase. Varying concentrations of LSCF–GDC composite with GDC (10 wt.%, 20 wt.% and 30 wt.%) were synthesized followed by calcination at 600 °C to remove water content and to achieve an adequate porous structure for oxygen absorption and desorption. These fabricated LSCF, GDC, and the nanocomposite specimens were characterized for microstructure, particle size etc. via. X-ray diffraction method (XRD), scanning electron microscope (SEM) and the laser particle size analyzer. This procedural approach helps to expand new methods for generating bi-functional duel nano-sized perovskites with great performance and stability which can be utilized for advancement of renewable energy sectors especially for rechargeable fuel batteries.
Analytical evaluation of moments of collision-induced scattering with Lennard-Jones (2n-n) potential
Authors: Somuncu Elif , Gokbulut Melek
Published: June 2020

In this work, an analytic expression for the moment of the collision-induced scattering with Lennard-Jones (2n-n) potential, defining the collision induced polarizability of molecules, is presented. It has been demonstrated that this expression gives accurate results for various values of parameters. The proposed analytical formula has been confirmed through comparisons with the results literature. Because of its computational efficiency, the suggested formula is found utility in the collision-induced polarizability in the molecular system. To our knowledge, this paper presents the first approach to the evaluation of the first two moments for collision-induced scattering of molecules by Lennard-Jones (2n-n) potential. The results obtained for the moment of collision-induced scattering for values n = 6 is in good agreement with literature.
Approaching black-box calculations of pump-probe fragmentation dynamics of polyatomic molecules

Published: June 2020

A general framework for the simulation of ultrafast pump-probe time resolved experiments based on Born-Oppenheimer molecular dynamics (BOMD) is presented. Interaction of the molecular species with a laser is treated by a simple maximum entropy distribution of the excited state occupancies. The latter decay of the electronic excitation into the vibrations is based on an on-the-fly estimation of the rate of the internal conversion, while the energy is distributed in a thermostat-like fashion. The approach was tested by reproducing the results of previous femtosecond studies on ethylene, naphthalene and new results for phenanthrene.

Homo and copolymer hydrogels of acrylamide and 2-hydroxyethyl methacrylate (HEMA) were synthesized by free radical addition polymerization. The synthesized hydrogels were characterized by scanning electron microscopy (SEM), thermal gravimetric and differential thermal analysis (TGA/DTA). The hydrogels were used as an adsorbent for the removal of toxic azo dye Basic blue 3 (BB3) in aqueous medium. To check the swelling property the equilibrium swelling of these synthesized hydrogels were established within 24 h. The effect of pH, time and temperature in the process of BB3 adsorption was studied in detail. The maximum adsorption of BB3 on hydrogels was occurred at pH 9 with 60 min equilibration time. The kinetic data were applied to pseudo first order, pseudo second order and intraparticle diffusion model. The obtained results indicate that the adsorption process, obey pseudo second order kinetics and is diffusion control. The negative value of ΔS and positive values of ΔG and ΔH showed that the adsorption process is orderliness, non-spontaneous and endothermic respectively in nature. The hydrogels were successfully regenerated from the mixture and used again in several steps without a reduction in their efficiency.
