Kandyd na Wyspach. O Emigracji Malcolma XD
Authors: Gromadzka Beata
Published: June 2022

Artykuł jest próbą usytuowania, wydanej w 2019 roku, powieści Emigracja Malcolma XD w tradycji literatury emigracyjnej i wśród nurtów współczesnej polskiej prozy migracyjnej o Polakach na Wyspach. Powieść kontynuuje satyryczno-groteskowe obrazy emigracyjnych losów ukazane przez Witolda Gombrowicza i Sławomira Mrożka. Emigracja jest polemiczna wobec współczesnej literatury migracyjnej ukazującej dylematy tożsamościowe w zróżnicowanej kulturowo rzeczywistości, ale jej forma, przejęta z internetowych gatunków, jest dla niej charakterystyczna.
On the influence of the first language on orthographic competences in German as a second language: a comparative analysis
Authors: Müller Hans-Georg , Schroeder Christoph
Published: June 2022

This article presents an empirical study on selected aspects of the orthographic performance of mono- and bilingual students in German. Particular attention is paid to the question whether a connection can be drawn between the orthographic performance of the bilingual students in German and their first language. For this purpose, a corpus is analyzed with data from approx. 800 test students. One group is monolingual in German, one is bilingual German–Turkish and one is bilingual German–Russian. A highly significant influence of Russian resp. Turkish on the performance to differentiate between tense and lax vowels is found. This corresponds to expectations insofar as in opposition to German, neither in Turkish nor in Russian, tense and lax vowels are distinguished phonologically. In other areas of orthography, this influence of the first language is not measurable or not to the same extent.
A Random Forest-based Approach to Combining and Ranking Seasonality Tests
Authors: Ollech Daniel , Webel Karsten
Published: June 2022

Virtually every seasonal adjustment software includes an ensemble of tests for assessing whether a given time series is in fact seasonal and hence a candidate for seasonal adjustment. However, such tests are certain to produce either agreeing or conflicting results, raising the questions how to identify the most accurate tests and how to aggregate the results in the latter case. We suggest a novel random forest-based approach to answer these questions. We simulate seasonal and non-seasonal ARIMA processes that are representative of the macroeconomic time series analysed regularly by the Bundesbank. Treating the time series’ seasonal status as a classification problem, we use the p-values of the seasonality tests implemented in the seasonal adjustment software JDemetra+ as predictors to train conditional random forests on the simulated data. We show that this aggregation approach avoids the size distortions of the JDemetra+ tests without sacrificing too much power compared to the most powerful test. We also find that the modified QS and Friedman tests are the most accurate ones in the considered ensemble.
The poset of morphism-extension classes of countable graphs
Authors: Aranda Andrés
Published: June 2022

Let XY
L,T
consist of all countable L-structures M that satisfy the axioms T and in which all homomorphisms of type X (these could be plain homomorphisms, monomorphisms, or isomorphisms) between finite substructures of M are restrictions of an endomorphism of M of type Y (for example, an automorphism or a surjective endomorphism). Lockett and Truss introduced 18 such classes for relational structures. For a given pair L, T however, two or more morphism-extension properties may define the same class of structures.

In this paper, we establish all equalities and inequalities between morphism-extension classes of countable graphs.

A Topological sphere theorem for contact CR-warped product submanifolds of an odd-dimensional unit sphere
Authors: Şahin Fulya , Şahin Bayram
Published: June 2022

In this paper, we investigate topological sphere theorems for compact minimal contact CR-submanifolds of odd dimensional unit sphere. We show that if an inequality involving the warping function and the scalar curvature of the fibers is satisfied, a compact minimal contact CR-warped product submanifold of the odd dimensional unit sphere is homeomorphic to the sphere. In particular case, for 5-dimensional unit sphere, we show that a 4-dimensional compact minimal contact CR-warped product submanifold is homeomorphic to a sphere if ∣∇lnf∣2 < 1 is satisfied. By using Bonnet-Myers’s theorem we give a result about fundamental group and by Leung’s theorem we obtain a result about homology groups of a contact CR-warped submanifold.
A systematic review of photocatalytic degradation of humic acid in aqueous solution using nanoparticles
Authors: Derakhshani Elham , Naghizadeh Ali , Arab-Zozani Morteza , Farkhondeh Tahereh
Published: June 2022

Objectives

Humic acid (HA) compounds in the disinfection processes of drinking water and wastewater are considered as precursors of highly toxic, carcinogenic and mutagenic disinfectant by-products. The aim of this study was to systematically review all research studies on the photocatalytic degradation of humic acid and to evaluate the laboratory conditions and results of these studies.

Content

The present systematic review was performed by searching the Scopus, PubMed, and web of science databases until December 2021. The parameters of type of catalyst, catalyst size, optimum pH, optimum initial concentration of humic Acid, optimum catalyst concentration, optimum time, light used and removal efficiency were investigated.

395 studies were screened and using the inclusion and exclusion criteria, in total, 20 studies met our inclusion criteria and provided the information necessary to Photocatalytic degradation of humic acid by nanoparticles. In the investigated studies, the percentage of photocatalytic degradation of humic acid by nanoparticles was reported to be above 70%, and in some studies, the removal efficiency had reached 100%.

Outlook

From the results of this systematic review, it was concluded that the photocatalytic process using nanoparticles has a high effect on the degradation of humic acid.
Making history matter more in evolutionary economic geography
Authors: Martin Ron , Sunley Peter
Published: June 2022

Our focus in this paper is on a somewhat curious feature of evolutionary economic geography, namely that although concerned withevolution – with processes ofhistoricalchange and transformation – evolutionary economic geography seems not to take history as seriously as it would be expected to do. We argue that evolutionary economic geography is inescapably an historical social science, and that as such would benefit from exploring the different ways in which history can be used in causal investigation, from problematising the different temporalities of economic change and transformation, and from giving more attention to appreciative theorising and narrative case study over variable-centred approaches.
May a Nonlocalized Postactivation Performance Enhancement Exist Between the Upper and Lower Body in Trained Men?
Authors: Bartolomei Sandro , De Luca Riccardo , Marcora Samuele Maria
Published: June 2022

Bartolomei, S, De Luca, R, and Marcora, SM. May a nonlocalized postactivation performance enhancement exist between the upper and lower body in trained men? J Strength Cond Res XX(X): 000–000, 2022—The aim of this study was to establish whether a resistance exercise for the upper body may generate a postactivation performance enhancement (PAPE) in the lower body. Thirteen resistance-trained men (age = 26.4 ± 3.3 years, body mass = 76.9 ± 6.3 kg, and height = 177.6 ± 5.2 cm) participated in the present investigation and were tested for upper-body and lower-body power (bench press throw and countermovement jump power [CMJP] tests). Subjects were also tested for maximum force and electromyographic (EMG) activation of quadriceps muscles while performing an isometric leg extension. All assessments were performed before and 8 minutes after a high-intensity (HI: 5 sets of 1 rep at 90% of 1 repetition maximum [1RM]) bench press protocol, a high-power protocol (POW: 5 sets of 1 rep at 30% of 1RM with maximum explosive intent), and a control trial (CON). Subjects performed all trials in a randomized order and on different days. A significant trial × time interaction was detected for CMJP (p = 0.049). This parameter was significantly increased following the HI protocol only (p = 0.024). A significant interaction was also noted for EMG with a significant improvement following the HI protocol (p = 0.032) and a significant decrease following the POW protocol (p = 0.020). No other significant effects were detected (p > 0.05). The results of this investigation indicate that a HI bench press protocol may produce a PAPE in the lower-body power and increase the neuromuscular activation of leg extensor muscles. The POW bench press protocol did not show any positive effects on lower-body performance. Athletes and practitioners may take advantage from the inclusion of upper-body HI resistance exercises throughout complex resistance workouts to improve lower-body power output.
Role of the Regional Representatives Council on Bicameral Parliament System
Authors: Alkadri Riska
Published: June 2022

After third amendment of the Constitution of 1945 (UUD 1945), the Regional Representatives Council (DPD) has been formulated. The amendment directly changed the parliamentary system in Indonesia, from unicameral into bicameral. The authorities of DPD in bicameral system still not clear enough. Although it is stipulated on Article 22D of UUD 1945, the authorities is still limited if compared with House of Representatives (DPR). This paper would discuss and examine the role of regional representative council as a second chamber from representative board in Indonesian. The paper would distinguish beside the authorities also the mechanism applied by DPD and DPR.

Authors: Setyawan Andry , Sulistianingsih Dewi , Yudistira Ivan Bhakti
Published: June 2022

Non-traditional Trademarks are also known as non-conventional trademarks develop due to business demands. The development of new trademarks like the sound, scent, three dimensions, and the hologram is defined as non-traditional trademarks and non-conventional trademarks of modern trademarks. The international and national regulations of the trademarks are done through several instruments. In Indonesia, they are governed in Act No 20 of 2016 and the regulations of the Ministry of Law and Human Rights No 67 of 2016. Despite their regulations which are accommodated in Act No 20 of 2016, the implementations of the regulation in Indonesia are as well-developed as that of other countries. The problems in the implementation of the non-traditional trademark protection are the responsibilities of the General Directorate of Intellectual Property especially in preparing the facilities and human resources.
Law Enforcement Against Fraud and/or Embezzlement (Study of KSP Intidana Central Java, Indonesia)
Authors: Andryanto Chandra
Published: June 2022

Crime recognized as a form of act which opposing the humanityâ€™s moral, harming people, has asocial nature, and violating law also criminal law. Because of that, crime must be eradicated, or must not let it continue until it evolves for the sake of discipline, security, and safety of people. One of the crimes that listed in criminal law (KUHP) is an act of fraud or embezzlement. The concept theory of this paper used the criminal sanctions which included: investigation, criminal act, the definition of scam or fraud, and the theories about cooperative. The paper indicated that the implementation of investigation process against perpetrator of fraud and/or embezzlement of Intidana Cooperative in Central Javaâ€™s Regional Police implemented after police report number: LP/B/426/XI/2015/Jateng/Reskrimum, November 5th, 2015 and Inquiry Warrant with number: 336b/XI/2015/Dit Reskrimum November 17th, 2015 also Investigative Warrant with number: 336a/XI/2015/DitReskrimum November 20th, 2015. The next step which the Police took is to call and inspect victims or witnesses, arrest of suspect, detention of suspects and seizure of evidence. The investigation process by the investigator and the assistant investigator begins by contacting the complainant and completing the initial investigation administration then conducting the inspection of witnesses and the collection of evidence, determining and seeking, conducting the suspect's examination by arrest and detention of the suspect. The dimensions of criminal law enforcement in the conduct of investigation on the perpetrators of criminal acts of fraud and/or embezzlement of the Intidana Cooperative in Central Javaâ€™s Regional Police is to minimize the occurrence of similar criminal acts, especially for the perpetrators in fraud and embezzlement cases in the future can be charged with criminal liability of fraud and embezzlement.
Penal Policy on Assets Recovery on Corruption Cases in Indonesia
Authors: Wahyudi Sugeng
Published: June 2022

Corruption is an extraordinary crime whose impact on actions can undermine a country, corruption is increasingly becoming increasingly common. Even though not a few of the former state officials or state officials until all the villages have felt how fierce the law enforcers, especially the KPK arrested them all, either hand-grabbing operations or the development of public reporting, impressed by them all were endless corruptors kept appearing , Law enforcement in this modern era is not only concerned with prosecution and prevention, in this case corruption is regulated by the return of state losses as asset recovery, which in turn will maximize the return of state losses from corruptors. As for the problems of this study are: 1. Why is the politics of criminal law (strafrechtpolitiek) in the framework of restoring state losses not significant with the real state losses due to criminal acts of corruption? 2. How is the politics of criminal law ideally (strafrechtpolitiek) implemented so that the maximum return on state losses due to corruption? The benefits of research consist of theoretical benefits and practical benefits. Theoretical benefits are expected to contribute to theoretical thinking in criminal law, especially concerning the politics of criminal law in the context of eradicating criminal acts of corruption. Practical benefits are expected to be able to provide information scientifically to the public both in general and specifically. This study uses a descriptive legal approach that is supported by primary, secondary and tertiary data obtained from documentation and literature studies then analyzed using qualitative descriptive analysis methods. The results showed that the Politics of Criminal Law in the Framework of Returning State Losses due to Corruption in Indonesia was not maximal, as evidenced by the lack of maximum or no maximum return on state losses for corruption, therefore recommendations on simplifying regulations in terms of early prevention or since In the beginning of corruption cases which caused a lot of damage to the state's financial need, there was a special formulation so that the handling could be maximized to restore state losses in corruption.
Final Income Tax: A Classic Contemporary Concept to Increase Voluntary Tax Compliance among Legal Professions in Indonesia
Authors: Tan David , Sudirman Lu
Published: June 2022

Legal profession such as advocate, law consultant and civil law notary is a profession in law that plays a dominant role in providing legal services to the Indonesian public. By providing the legal services, they are entitled to receive honorarium in return. Empirical facts actually show that these legal professionsâ€™ tax compliance are still lacking. Main questions in this research are the legal aspects related to income tax on honorariums received by legal professions in connection with the legal services they provide and the concept of reconstruction to the laws and regulations related to income tax on honorarium received by legal professions. This research will answer the legal aspects related to the laws on income tax on these legal professionsâ€™ honorarium in Indonesia and the concept of reconstruction of the regulations related to income tax on these legal professionsâ€™ honorarium so that it may provide positive impetus to the legal professionâ€™s tax compliance, and in turn contributes to the welfare of the nation. This normative juridical research approach is conducted using secondary data consisting of primary, secondary and tertiary legal materials. The aspects of the reconstruction are using the philosophical, constitutional and juridical paradigmatic studies with the Utilitarianism Theory by Jeremy Bentham, Progressive Legal Theory by Satjipto Rahardjo and Legal System Theory by Lawrence M. Friedman as basis of analysis. The results of this study found that there is a concept of contemporary reconstruction to the laws and regulations related to the income tax on honorarium received by legal professionals.
Discourse on Legal Expression in Arrangements of Corruption Eradication in Indonesia
Authors: Hidayat Shubhan Noor , Karjoko Lego , Hermawan Sapto
Published: June 2022

The purpose of this research is to explain and examine the expansion of the absolute competence of the Administrative Court (hereinafter referred to as PTUN) after the Government Administration Law is promulgated and the implications of the application of the Administrative Law on legal certainty to eradicate and enforce corruption in Indonesia. This research uses a normative juridical research method and uses a statutory approach (statute approach). The results showed "that there are several forms of expansion of PTUN competencies, such as the authority that acts factually, the authority, administrative authorization, decide on positive fictitious decisions, and discretionary trials". Meanwhile, the implications of the Government Administration Law on corruption are known as corruption crimes, which are true. So, in this context, there are at least two problems, namely: â€œ1. If the authorized court case is carried out by the state government which is submitted to the court simultaneously, to the State Administrative Court and to the District Court in a corruption case? 2. If at any time a PTUN decision has been issued stating that it is not authorized, but there is also a party who submits the case to the District Court on charges of corruption. What is the attitude of the District Court, whether to accept the PTUN decision on the case or choose to override the PTUN decisionâ€.  So the author is of the view that in this case there is concern that it will complicate the prosecution or eradication of criminal acts of corruption in the case of abuse of authority committed by government officials.

Published: June 2022

Glucocorticoids have short- and long-term effects on adrenal gland function and development. RNA sequencing (RNA-seq) was performed to identify early transcriptomic responses to the synthetic glucocorticoid, dexamethasone (Dex), in vitro and in vivo. In total, 1711 genes were differentially expressed in the adrenal glands of the 1-h Dex-treated mice. Among them, only 113 were also considered differentially expressed genes (DEGs) in murine adrenocortical Y-1 cells treated with Dex for 1 h. Gene ontology analysis showed that the upregulated DEGs in the adrenal gland of the 1-h Dex-treated mice were highly associated with the development of neuronal cells, suggesting the adrenal medulla had a rapid response to Dex. Interestingly, only 4.3% of Dex-responsive genes in the Y-1 cell line under Dex treatment for 1 h were differentially expressed under Dex treatment for 24 h. The heatmaps revealed that most early responsive DEGs in Y-1 cells during 1 h of treatment exhibited a transient response. The expression of these genes under treatment for 24 h returned to basal levels similar to that during control treatment. In summary, this research compared the rapid transcriptomic effects of Dex stimulation in vivo and in vitro. Notably, adrenocortical Y-1 cells had a transient early response to Dex treatment. Furthermore, the DEGs had a minimal overlap in the 1-h Dex-treated group in vivo and in vitro.

Published: June 2022

Objective

To understand whether thyroid cells can be directly infected by the SARS-CoV-2 virus and to establish a putative correlation with the expression of the host entry machinery: ACE-2, TMPRSS2, and furin.

Methods

We assessed the presence of SARS-CoV-2 virus at the gene level by RT-PCR, viral RNA transcripts localization by in situ hybridization, and by detecting viral proteins by immunohistochemistry for the nucleocapsid and the spike proteins. Furthermore, we also described the immunoexpression of key host factors for virus entry in the COVID-19 thyroid samples.

Results

We performed RT-PCR for SARS-CoV-2 in all autopsy specimens and detected viral genome positivity in 13 of 15 thyroid tissues and in a lung specimen. In 9 of the 14 positive samples, we were also able to confirm SARS-CoV-2 signal by in situ hybridization. Immunohistochemistry for the viral nucleocapsid and spike protein was also positive for ten and nine of the RT-PCR-positive cases, respectively, but revealed a lower sensitivity. We also described, for the first time in a COVID-19 series, the immunohistochemical expression of ACE-2, TMPRSS2, and furin in the thyroid.

Conclusions

Our results obtained in thyroid specimens from deceased COVID-19 patients indicate that thyrocytes can be directly infected by SARS-CoV-2 since we detected the presence of SARS-CoV-2 genome in follicular cells. Nevertheless, we did not find a clear correlation between the presence of viral genome and the expression of the host factors for virus entry, namely ACE-2, TMPRSS2, and furin.

Published: June 2022

Myxoma is the most common benign cardiac tumor. Absent pulmonary valves, often treated surgically in childhood, are associated with 3-6% of tetralogy of Fallot. It is unusual for absent pulmonary valves without other congenital heart diseases to be asymptomatic until adulthood. Here, we report the unique case of an 80-year-old female with right ventricular outflow tract myxoma and absent pulmonary valve that has, to our knowledge, never been reported. We successfully performed a simple mass resection and pulmonary valve implantation.
Pskov place names "Полонище" and "Поле"
Authors: Vvedenskiy Anton
Published: June 2022

The article suggests a new etymology of the Pskov microtoponym Polonishche. Based on the common Slavic meaning of the word polon "a clean place free for pasture or haymaking", preserved in Polesye region, as well as the semantics of the suffix -ishche, the article hypothesizes that Polonishche in Pskov was originally called the territory near the city where cattle were grazed. Based on the data of the Pskov chronicles, the article hypothesizes that the territory between the city walls of 1309 and 1375 was never called Polonishche, as it is commonly believed in modern historiography, while the early mentions of the microtoponym Polonishche in the text of the Pskov Second Chronicle in articles for the XIV century are late interpolations into the chronicle text. The microtoponym Polonishche originally designated the territory behind the wall of 1375, and gradually "replaced" the microtoponym Polye, which designated the territory located behind residential buildings adjacent to the city walls. The microtoponym Polye "field" most likely appeared before Polonishcha, but the chronicle data for the XIV century is very difficult to interpret, since the term Polye or field could well be used by chroniclers in a physiographic, rather than toponymic meaning. After the construction of the wall of the Roundabout City in 1465, the distinction between these names became clearer. Polonishche continued to be called the territory between the walls of 1375 and 1465, and the Polye began to denote the area behind the wall of the Roundabout City.

Published: June 2022

Intravascular imaging with optical coherence tomography (OCT) and intravascular ultrasound provides superior visualization of the culprit plaques for acute coronary syndromes (ACS) compared with coronary angiography. Combined with angiography, intravascular imaging can be used to instigate ‘precision therapy’ for ACS. Post-mortem histopathology identified atherothrombosis at the exposed surface of a ruptured fibrous cap as the main cause of ACS. Further histopathological studies identified intact fibrous caps and calcified nodules as other culprit lesions for ACS. These plaque types were subsequently also identified on intravascular imaging, particularly with the high-resolution OCT. The less-common non-atherothrombotic causes of ACS are coronary artery spasm, coronary artery dissection, and coronary embolism. In this review, the authors provide an overview of clinical studies using intravascular imaging with OCT in the diagnosis and management of ACS.
Bipartite Domination in Graphs
Authors: Bachstein Anna , Goddard Wayne , Henning Michael A.
Published: June 2022

The bipartite domination number of a graph is the minimum size of a dominating set that induces a bipartite subgraph. In this paper we initiate the study of this parameter, especially bounds involving the order, the ordinary domination number, and the chromatic number. For example, we show for an isolate-free graph that the bipartite domination number equals the domination number if the graph has maximum degree at most 3; and is at most half the order if the graph is regular, 4-colorable, or has maximum degree at most 5.
Playing Out
Authors: Flynn Mathew , Anderson Richard
Published: June 2022

Drawing on the findings of practitioner group consultations (n=49) and an online survey of music makers (n=37), this article illustrates the devastating impact of 18 months without full-capacity live events on the financial, musical and social wellbeing of the Liverpool City Region’s (LCR) music sector. The analysis shows how uncertainties concerning a return to normal operations, access to funding support, working within socially distanced limitations, and dealing with changing regulations have underlined the live music workers’ experience of the pandemic as well as how a sense of uncertainty persists despite a return to full-capacity events in July 2021. The findings show that digital alternatives partially helped alleviate lockdown’s detrimental effects but, overall, the sector viewed live-streaming as a “stop-gap” incomparable to the conventional concert experience. The research concludes by observing that, despite the numerous practical and economic adaptations and online advances that ensured the sector’s survival, the return to “business as usual” also means a return to pre-pandemic industry economics, which often function to the detriment of the musicians on whom the regional live sector’s operational and financial recovery depend.
Perfiles de gratitud, necesidades psicológicas y su relación con la resiliencia en estudiantes no tradicionales
Authors: Suárez-Cretton Ximena , Castro-Méndez Nelson
Published: June 2022

El objetivo del estudio fue identificar perfiles de gratitud, necesidades psicológicas básicas y su relación con la resiliencia en estudiantes no tradicionales adultos-trabajadores. Se utilizó un diseño no experimental, transversal, descriptivo y un análisis de clústeres; 114 estudiantes universitarios respondieron tres instrumentos para evaluar las variables. Los resultados muestran 4 perfiles, sólo uno se diferencia significativamente en resiliencia, en ventaja de los otros, presentando altos niveles en gratitud y necesidades psicológicas. Los tres perfiles más desfavorecidos en las variables obtienen menor resiliencia. Uno de ellos, equivalente a un 10,5% de los estudiantes, presenta también baja necesidad de autonomía. Se concluye que las intervenciones deberían estar focalizadas en los estudiantes jóvenes, para fortalecer su necesidad de autonomía y resiliencia.
Oralidad, escritura y puntuación en la fraseología histórica. El «Libro de refranes» de Pedro Vallés (1549)
Authors: Llamas-Pombo Elena
Published: June 2022

Como contribución a la fraseología histórica del español, este artículo presenta un modelo de análisis y clasificación de las formas sapienciales del siglo XVI desde el punto de vista de las relaciones entre oralidad y escritura, a partir de un estudio de las unidades léxicas recopiladas por Pedro Vallés en el Libro de refranes (Zaragoza, 1549). Por una parte, se considera el factor métrico-rítmico en la composición de las formas de discurso repetido; por otra parte, se estudia la codificación gráfica de estas unidades en cuanto a los signos de puntuación y a los fenómenos de secuenciación gráfica. Los resultados del análisis permiten postular que la puntuación del impreso es del paremiógrafo Pedro Vallés, y no fruto del trabajo editorial de un impresor.
Transcripción de la entonación de la variedad del andaluz de Álora según el sistema Sp_ToBI
Authors: Armero-Pérez María-Cristina , Moreno-Torres-Sánchez Ignacio , Roseano Paolo
Published: June 2022

En los últimos años se han ido desarrollando numerosos estudios sobre la entonación de las lenguas basados en el modelo métrico-autosegmental establecido por Janet Pierrehumbert. El objetivo de este trabajo es el de describir los principales contornos de F0 en diferentes tipos de enunciados de la localidad de Álora (Málaga), un punto situado en una zona de confluencia entre la variedad oriental y occidental andaluzas. Con ese fin, se han grabado mediante la técnica del Discourse Completion Task 224 oraciones producidas por 7 hablantes de esa localidad. Los contornos entonativos así obtenidos se han anotado mediante el sistema de transcripción Sp_ToBI. Además de describir la entonación de los diferentes tipos de enunciados, en este trabajo se realiza también una comparación con las variedades del espanol central peninsular, estudiado por Estebas-Vilaplana y Prieto, y del jerezano, analizado por Henriksen y García-Amaya. Los resultados indican que el habla de Álora se acerca entonativamente más al jerezano que al español peninsular central, aunque se diferencia del primero en varias modalidades oracionales (declarativas neutras de más de una unidad tonal, declarativas de obviedad, interrogativas parciales neutras, órdenes, vocativos insistentes).
El tratamiento de la sintaxis en la Colombia del siglo XIX
Authors: Martínez-Atienza-de-Dios María
Published: June 2022

Analizamos en este trabajo el tratamiento de la sintaxis en un corpus de obras destinadas a la enseñanza de la gramática en las escuelas de Colombia durante el siglo XIX. En particular, nos concentramos en cuatro temas: 1) la posible distinción entre sintaxis natural y figurada; 2) el concepto de régimen; 3) el tratamiento de los casos; y 4) los criterios y la terminología utilizada para definir las unidades oracionales. Comprobaremos que se manifiesta una evolución en la doctrina sintáctica desde las obras de las primeras décadas del siglo, con tendencia latinizante y en las que predomina la influencia de la Academia, hasta las últimas, donde es notable el influjo de Andrés Bello, pasando por las gramáticas de mediados de la centuria, cuando, junto al venezolano, la figura de Vicente Salvá es considerada como referente.
Nutritional management of immediate hypersensitivity to legumes in vegetarians
Authors: Jardim-Botelho Anne , Lopes de Oliveira Lucila Camargo , Motta-Franco Jackeline , Solé Dirceu
Published: June 2022

Vegetarianism is becoming a common practice among people. Products of vegetable origin are also on the rise, such as vegetable “milk” and legume-based snacks, which may lead to legume sensitivity and allergies in vegetarian diet followers. Furthermore, products derived from legumes, such as lupin flour or fenugreek powder, are often used as food additives. They function as hidden allergens, not always evident on the precautionary labeling, favoring allergic reactions. As dietary allergen restriction is the fundamental pillar in managing patients with food allergies, this review aims to reflect on practical aspects—diagnosis and nutritional management—in managing legume allergies in vegetarians, aiming to reduce the negative nutritional impact of an even more restrictive diet.

Proton exchange membrane water electrolysis (PEMWE) performs the electrolysis of water to produce hydrogen, a source of clean and renewable energy. The most used commercial electrolyte in PEMWE is the Nafion membrane, a material that is expensive and difficult to recycle. The partial replacement of Nafion with cellulose nanocrystals (CNCs) can produce composite membranes can increased electrical, mechanical and biodegradability properties. In this sense, the objective of this work is to study the elaboration of nanocomposites (Nafion-CNC) aiming at developing high-performance electrolytes for application in PEMWE. The effects of adding CNCs to Nafion were evaluated. Nafion membranes were produced with two types of CNCs, one obtained by enzymatic hydrolysis and the other by acid hydrolysis (commercial). The addition of both CNCs has similar effects on Nafion's properties. For samples with both commercial and enzymatic CNC, an increase in the modulus of elasticity (10% and 40% respectively) and maximum stress (10% and 13% respectively) was observed. The two nanocomposites showedlower initial thermal degradation temperatures, however, they still showed sufficient stability (Tonset > 170°C) for application in PEMWE (standard operating temperature <100°C). Furthermore, there was a significant increase in the humidification capacity and increase in conductivity. Composite membranes were tested in PEMWE and their usability was proven.
Viver é etecetera (Guimarães Rosa) - Rastros de vidas docentes
Authors: Barros Maria Elizabeth Barros de , Rodrigues Heliana de Barros Conde
Published: June 2022

O artigo apresenta uma pesquisa com docentes de redes públicas de ensino da região sudeste do Brasil. Teve como cenário a pandemia de COVID-19. Objetivou-se pensar os efeitos da pandemia na educação a partir do método biografemático, inspirado na formulação de Roland Barthes sobre biografemas. As entrevistas foram realizadas na modalidade on-line. Os relatos resultantes indicam a relevância de narrar histórias, colocando-as em diálogo para repensar práticas docentes. O ato de narrar favorece o ato de pensar e, ao exercitar o pensamento, força a experiência a se recriar, reposicionando os docentes em suas práticas e possibilitando, desse modo, a invenção de modos outros de ser ensinante.
Fast and Exact Top-k Algorithm for PageRank
Authors: Fujiwara Yasuhiro , Nakatsuji Makoto , Shiokawa Hiroaki , Mishima Takeshi , Onizuka Makoto
Published: June 2022

To obtain high PageRank score nodes, the original approach iteratively computes the Page-Rank score of each node until convergence by using the whole graph. If the graph is large, this approach is infeasible due to its high computational cost. The goal of this study is to find top-k Page\-Rank score nodes efficiently for a given graph without sacrificing accuracy. Our solution, F-Rank, is based on two ideas: (1) It iteratively estimates lower/upper bounds of Page\-Rank scores, and (2) It constructs subgraphs in each iteration by pruning unnecessary nodes and edges to identify top-k nodes. Our theoretical analysis shows that F-Rank guarantees result exactness. Experiments show that F-Rank finds top-k nodes much faster than the original approach.
Better Human Computation Through Principled Voting
Authors: Mao Andrew , Procaccia Ariel , Chen Yiling
Published: June 2022

Designers of human computation systms often face the need to aggregate noisy information provided by multiple people. While voting is often used for this purpose, the choice of voting method is typically not principled. We conduct extensive experiments on Amazon Mechanical Turk to better understand how different voting rules perform in practice. Our empirical conclusions show that noisy human voting can differ from what popular theoretical models would predict. Our short-term goal is to motivate the design of better human computation systems; our long-term goal is to spark an interaction between researchers in (computational) social choice and human computation.
The Effects of Performance-Contingent Financial Incentives in Online Labor Markets
Authors: Yin Ming , Chen Yiling , Sun Yu-An
Published: June 2022

Online labor markets such as Amazon Mechanical Turk (MTurk) have emerged as platforms that facilitate the allocation of productive effort across global economies. Many of these markets compensate workers with monetary payments. We study the effects of performance-contingent financial rewards on work quality and worker effort in MTurk via two experiments. We find that the magnitude of performance-contingent financial rewards alone affects neither quality nor effort. However, when workers working on two tasks of the same type in a sequence, the change in the magnitude of the reward over the two tasks affects both. In particular, both work quality and worker effort increase (alternatively decrease) as the reward increases (alternatively decreases) for the second task. This suggests the existence of the anchoring effect on workers’ perception of incentives in MTurk and that this effect can be leveraged in workflow design to increase the effectiveness of financial incentives.
A Fast Bandit Algorithm for Recommendation to Users With Heterogenous Tastes
Authors: Kohli Pushmeet , Salek Mahyar , Stoddard Greg
Published: June 2022

We study recommendation in scenarios where there's no prior information about the quality of content in the system. We present an online algorithm that continually optimizes recommendation relevance based on behavior of past users. Our method trades weaker theoretical guarantees in asymptotic performance than the state-of-the-art for stronger theoretical guarantees in the online setting. We test our algorithm on real-world data collected from previous recommender systems and show that our algorithm learns faster than existing methods and performs equally well in the long-run.

Published: June 2022

In this paper we introduce the Target Oriented Network Intelligence Collection (TONIC) problem, which is the problem of finding profiles in a social network that contain information about a given target via automated crawling. We formalize TONIC as a search problem and a best-first approach is proposed for solving it.Several heuristics are presented to guide this search.These heuristics are based on the topology of the currently known part of the social network.The efficiency of the proposed heuristics and the effect of the graph topology on their performance is experimentally evaluated on the Google+ social network.
A Hybrid Architectural Approach to Understanding and Appropriately Generating Indirect Speech Acts
Authors: Briggs Gordon , Scheutz Matthias
Published: June 2022

Current approaches to handling indirect speech acts (ISAs) do not account for their sociolinguistic underpinnings (i.e., politeness strategies). Deeper understanding and appropriate generation of indirect acts will require mechanisms that integrate natural language (NL) understanding and generation with social information about agent roles and obligations,which we introduce in this paper. Additionally, we tackle the problem of understanding and handling indirect answers that take the form of either speech acts or physical actions, which requires an inferential, plan-reasoning approach. In order to enable artificial agents to handle an even wider-variety of ISAs, we present a hybrid approach, utilizing both the idiomatic and inferential strategies. We then demonstrate our system successfully generating indirect requests and handling indirect answers, and discuss avenues of future research.
Negotiated Learning for Smart Grid Agents: Entity Selection based on Dynamic Partially Observable Features
Authors: Reddy Prashant , Veloso Manuela
Published: June 2022

An attractive approach to managing electricity demand in the Smart Grid relies on real-time pricing (RTP) tariffs, where customers are incentivized to quickly adapt to changes in the cost of supply. However, choosing amongst competitive RTP tariffs is difficult when tariff prices change rapidly. The problem is further complicated when we assume that the price changes for a tariff are published in real-time only to those customers who are currently subscribed to that tariff, thus making the prices partially observable. We present models and learning algorithms for autonomous agents that can address the tariff selection problem on behalf of customers. We introduce 'Negotiated Learning', a general algorithm that enables a self-interested sequential decision-making agent to periodically select amongst a variable set of 'entities' (e.g., tariffs) by negotiating with other agents in the environment to gather information about dynamic partially observable entity 'features' (e.g., tariff prices) that affect the entity selection decision. We also contribute a formulation of the tariff selection problem as a 'Negotiable Entity Selection Process', a novel representation. We support our contributions with intuitive justification and simulation experiments based on real data on an open Smart Grid simulation platform.
Domain-Specific Heuristics in Answer Set Programming
Authors: Gebser Martin , Kaufmann Benjamin , Romero Javier , Otero Ramón , Schaub Torsten , Wanko Philipp
Published: June 2022

We introduce a general declarative framework for incorporating domain-specific heuristics into ASP solving. We accomplish this by extending the first-order modeling language of ASP by a distinguished heuristic predicate. The resulting heuristic information is processed as an equitable part of the logic program and subsequently exploited by the solver when it comes to non-deterministically assigning a truth value to an atom. We implemented our approach as a dedicated heuristic in the ASP solver clasp and show its great prospect by an empirical evaluation.
Bribery in Voting With Soft Constraints
Authors: Pini Maria Silvia , Rossi Francesca , Venable Kristen Brent
Published: June 2022

We consider a multi-agent scenario where a collection of agents needs to select a common decision from a large set of decisions over which they express their preferences. This decision set has a combinatorial structure, that is, each decision is an element of the Cartesian product of the domains of some variables. Agents express their preferences over the decisions via soft constraints. We consider both sequential preference aggregation methods (they aggregate the preferences over one variable at a time) and one-step methods and we study the computational complexity of influencing them through bribery. We prove that bribery is NPcomplete for the sequential aggregation methods (based on Plurality, Approval, and Borda) for most of the cost schemes we defined, while it is polynomial for one-step Plurality.
Qualitative Planning under Partial Observability in Multi-Agent Domains
Authors: Brafman Ronen , Shani Guy , Zilberstein Shlomo
Published: June 2022

Decentralized POMDPs (Dec-POMDPs) provide a rich, attractive model for planning under uncertainty and partial observability in cooperative multi-agent domains with a growing body of research. In this paper we formulate a qualitative, propositional model for multi-agent planning under uncertainty with partial observability, which we call Qualitative Dec-POMDP (QDec-POMDP). We show that the worst-case complexity of planning in QDec-POMDPs is similar to that of Dec-POMDPs. Still, because the model is more “classical” in nature, it is more compact and easier to specify. Furthermore, it eases the adaptation of methods used in classical and contingent planning to solve problems that challenge current Dec-POMDPs solvers. In particular, in this paper we describe a method based on compilation to classical planning, which handles multi-agent planning problems significantly larger than those handled by current Dec-POMDP algorithms.
