Local pragmatics: Issues and reflection
Authors: Huang Qiao
Published: September 2021

Pragmatic effects triggered by embedded structure have caused problems to Grice’s Theory of Conversational Implicature. This long-standing view is challenged by local pragmatics proposed by Mandy Simons. As to the theoretical development, Robyn Carston, Francois Recanati, and Emma Borg respectively raise their comments, while Simons positively responds to these commentaries and further elaborates her stance. In this article, the argumentation among these scholars is presented first, and much attention is paid to the value and influence of the argumentation, which would shed light on the current debate between semantics and pragmatics.

Background: Asthma is a chronic inflammatory condition of the airways with a complex pathophysiology. Stratification of asthma subtypes into phenotypes and endotypes should move the field forward, making treatment more effective and personalized. Eosinophils are the key inflammatory cells involved in severe eosinophilic asthma. Given the health threat posed by eosinophilic asthma, there is a need for reliable biomarkers to identify affected patients and treat them properly with novel biologics. microRNAs (miRNAs) are a promising diagnostic tool. Objective: The aim of this study was to identify serum miRNAs that can phenotype asthma patients. Methods: Serum miRNAs of patients with eosinophilic asthma (N=40) and patients with noneosinophilic asthma (N=36) were evaluated using next-generation sequencing, specifically miRNAs-seq, and selected miRNAs were validated using RT-qPCR. Pathway enrichment analysis of deregulated miRNAs was performed. Results: Next-generation sequencing revealed 15 miRNAs that were expressed differentially between eosinophilic and noneosinophilic asthma patients, although no differences were observed in the miRNome between atopic and nonatopic asthma patients. Of the 15 miRNAs expressed differentially between eosinophilic and noneosinophilic asthma patients, hsa-miR-26a-1-3p and hsa-miR-376a-3p were validated by RT-qPCR. Expression levels of these 2 miRNAs were higher in eosinophilic than in noneosinophilic asthma patients. Furthermore, expression values of hsa-miR-26a-1-3p correlated inversely with peripheral blood eosinophil count, and hsa-miR-376a-3p expression values correlated with FeNO values and the number of exacerbations. Additionally, in silico pathway enrichment analysis revealed that these 2 miRNAs regulate signaling pathways associated with the pathogenesis of asthma. Conclusion: hsa-miR-26a-1-3p and hsa-miR-376a-3p could be used to differentiate between eosinophilic and noneosinophilic asthma.

Authors: Lacerda Mariana Fagundes de Oliveira , Lemos Maiara da Silva , Carneiro Zenaide de Oliveira Novais
Published: September 2021

O presente trabalho visa realizar a descrição da colocação dos clíticos pronominais nas orações finitas com verbo único e grupos verbais em amostras representativas das vertentes do PB culto, semiculto e popular, segundo Lucchesi (2015), através de cartas pessoais manuscritas por escreventes de escolaridade diversa da região do sertão baiano que compõem acervos disponibilizados no Corpus Eletrônico de Documentos Históricos do Sertão (CE-DOHS/UEFS) e em Almeida, Carneiro e Oliveira (2011). A pesquisa fundamentada pelos pressupostos teóricos da linguística sócio-histórica (MATTOS E SILVA, 2008), segue as agendas propostas pelo Projeto Para a História do Português Brasileiro (PHPB), conforme Lobo (2009), contribuindo com o campo de estudo das mudanças linguísticas e com o campo de reconstrução da história social linguística. A finalidade, foi verificar se, nos corpora desta pesquisa, pode-se atestar a hipótese levantada por Lucchesi (1994) acerca da tendência à aproximação das vertentes no PB, decorrente dos processos de urbanização e industrialização no século XX. Por fim, a aproximação entre as vertentes culta, semiculta e popular, confirma a hipótese de Lucchesi (1994).

Published: September 2021

O século XIX constitui-se como um período importante para o entendimento da historicidade da língua em solo brasileiro. Ancorado no campo teórico da História das Ideias Linguísticas (Auroux) na relação com a da Análise do Discurso (Pêcheux, Orlandi), neste artigo, tem-se como objetivo dar a saber da composição de um arquivo construído a partir das notas de rodapé de Alencar em dois de seus romances, O Guarani e Iracema, totalizando 202 entradas. As notas, sobre palavras e expressões, dizem respeito à língua e funcionam como verbetes. Nossa posição é a de que as notas de rodapé de Alencar se inscrevem na intensa produção de vocabulários do século XIX no Brasil, não apenas como listagens de palavras, mas no exaustivo trabalho daquele que captura, descreve e interpreta. Tal arquivo irá permitir estudos diversos sobre a língua no século XIX bem como possibilitará uma reflexão sobre o lugar do escritor na gramatização da língua em solo brasileiro.
Declarações equativas tautológicas com nome próprio
Authors: Nogueira Márcia Teixeira , Silva Leosmar Aparecido da
Published: September 2021

Este artigo tem o objetivo de analisar declarações equativas tautológicas com nomes próprios (Np) como Maria é Maria. Com suporte teórico em Wierzbicka (2003) e Meibauer (2008), bem como em trabalhos de Keizer (2008) e Hengeveld e Mackenzie (2008), o artigo apresenta, inicialmente, uma discussão teórica sobre os aspectos conceituais e funcionais da tautologia, bem como sobre a natureza referencial ou predicativa do nome próprio pós-cópula, para, em seguida, analisar dados coletados da internet, em que a estrutura Np é Np é usada. Os resultados revelam que as declarações equativas tautológicas com nome próprio, no contexto em que aparecem, constituem uma estratégia argumentativa por meio da qual se assevera a singularidade da representação mental de uma entidade discursiva, valorada positiva ou negativamente.

Published: September 2021

The aim of the study was to investigate the hyaluronic acid concentration in middle ear fluid of patients with cleft palate as an indicator of the severity of the disease. Hyaluronic acid was examined in the middle ear fluid of 65 children (48 boys and 17 girls) subjected to cleft lip surgery in neonatal period up to 10 days of age. Patients were divided into 3 groups according to the course of the disease. First group consists of 15 patients with favorable course, second group consist of 25 patients with moderate course, third group included 25 patients with an adverse course. Hyaluronic acid levels were determined by commercially available immunoassay. The concentrations of hyaluronic acid in the middle ear fluid were as follows (mean+SEM): favorable course: 14253+2393 µg/l, moderate course: 7503+1345 µg/l, adverse course: 5905+2393 µg/l. Patients with adverse course and moderate course had significantly decreased hyaluronic acid levels in middle ear fluid compared to the patients with favorable course (P=0.02 and P=0.0018). Hyaluronic acid concentration is related to the course of the disease and the lowest values are most frequent in patients with an adverse course.

Published: September 2021

According to the 2018 Global Nutrition Report, the habit of school-aged children choosing meals is still bad over the world. Around 30.3 % of school-aged children do not eat fruit daily, whereas 43.7 % consume soda daily. This study aims to increase student's knowledge about the material sources of nutrients in food through a game of grouping foodstuffs using a food model with a constructivist learning approach designed by the author. The participants in this study were 33 SDIT Raudhatul Jannah Lubuklinggau grade 4,5 and 6 students. The method used in this study uses an experimental design with a pre and post-test approach without control. Total sampling was used for sampling, and the Wilcoxon test was used for interpretation. This study was completed in March of  2021. Research results show a p-value of .000 (<.05), indicating that students' awareness of the material sources of nutrients in food increased after they were given a game grouping food ingredients using a food model. It is recommended that educators be able to provide students with learning resources that take a constructivist approach, such as games that actively engage students, so that students' awareness can be developed through direct experiences.

Regional taxes and levies are part of the source of Regional Original Income or better known as (PAD), which is a regional asset that is part of the income of a region. The type of research used in this legal research is empirical normative legal research, namely research based on primary, secondary and tertiary legal materials with interpretation and systematization between laws and regulations. it is necessary to adjust the retribution rate, especially regarding the general service retribution regarding cleaning/waste services. This is as explained in Article 155 paragraph (1) of Law Number 28 of 2009 concerning Regional Taxes and Regional Levies, which states that the Levy Tariff is reviewed at the latest every 3 (three) years. So here it is very clear for Regional Regulations that many regions have not updated their rules, and are expected to be re-evaluated due to economic developments and also the price index.

Political Leadership and Transactional Leadership
Authors: Efianda Angela , Iswahyuni Iswahyuni
Published: September 2021

Leadership is the activity to influences others in order to guide them towards a certain goal (Miftah Thoha, 2013; 121). A leader is someone with capabilities and advantages so that they can influences and guides others to work together for a similar goal. Political leadership covers a wide range of topics due to how a country are constituted by structures designed to run it. Transactional leadership occurs because by default leadership is a form of social control between the leader and its subordinates. Transactional leadership or often called transactional politics has become its own problem. A normal kind of leadership when applied on other fields might become biased and pose a certain problem in the political sphere. Transactional politics can be hard to avoid especially in a presidential government system which involves multiple political parties. Transactional leadership is the kind of leadership modeled to attain a certain goal by giving rewards as well as guiding and controlling the subordinates so that they can work effectively and efficiently. It also focuses more on inter individual transaction, between the members and its managers.

Published: September 2021

In this work, it is shown that the image formed as a result of the passage of coherent radiation through the crystal has certain characteristic features. When the crystal is rotated with respect to the propagation axis of the investigated beam, the formation of the intensity distribution of a complex structure associated with the transformation of the flat image into volumetric was detected at the output. Crystalline plates can be used to form the distribution of a continuous flat light field in the implementation of a real 3D scene, which can provide a three-dimensional image on a television screen, as well as on a computer monitor screen. It can also be used in billboards. The three-dimensional image obtained in this way can be observed directly with the eyes of a person (without using special glasses. Thus, the information capacity of the image on the screen increases, and the perception of the picture approaches real conditions.
Spectral expansion method for analysis of a system with shifted Erlang and hyper-Erlang distributions
Authors: Tarasov Veniamin N. , Bakhareva Nadezhda F.
Published: September 2021

In this paper, we obtained a spectral expansion of the solution to the Lindley integral equation for a queuing system with a shifted Erlang input flow of customers and a hyper-Erlang distribution of the service time. On its basis, a calculation formula is derived for the average waiting time in the queue for this system in a closed form. As you know, all other characteristics of the queuing system are derivatives of the average waiting time. The resulting calculation formula complements and expands the well-known unfinished formula for the average waiting time in queue in queuing theory for G/G/1 systems. In the theory of queuing, studies of private systems of the G/G/1 type are relevant due to the fact that they are actively used in the modern theory of teletraffic, as well as in the design and modeling of various data transmission systems.

Authors: MERGEN Haluk , ERDEM Elif , AKAR Harun
Published: September 2021

A young case diagnosed with peritoneal tuberculosis with ascites will be presented here. Conditions that may pose a significant risk for the development of tuberculous peritonitis; poor hygiene, overpopulation, consumption of unpasteurized milk, cirrhosis, peritoneal dialysis, HIV infection, drug abuse and inadequate access to healthcare. In general, the tuberculosis agent reaches the gastrointestinal system via hematogenous route, ingestion of infected sputum, or direct spread. Peritoneal TB should be considered in the differential diagnosis in patients with abdominal pain, diarrhea, weight loss, anorexia, night sweats, presence of ascitic fluid, bilateral pleural effusion, pleural nodule appearance, and findings suggestive of peritonitis carcinomatosis, as in our case. Peritoneal tuberculosis is rarely diagnosed, without a high index of suspicion for this disease.

The healthcare sector is currently under enormous pressure and the COVID-19 pandemic does not improve this situation. The quality of healthcare will be negatively impacted when this pressure continues in the longer term. In 2050 it is expected that a total of 2.1 billion people will be aged 60+ years old. To overcome the increasing demand for healthcare by this age group, various studies are being conducted into various technological solutions, such as social robots. In this study, the Alpha Mini social robot was used in an experiment to research which tasks a social robot could assist with, to reduce the work pressure of healthcare professionals and to help the elderly live longer at their own homes. The experiment was carried out using interviews with healthcare professionals and informal caregivers about the demonstrated Alpha Mini. In addition to the experiment and interviews a survey was sent out to 237 healthcare organizations in the Netherlands to identify the 1) work pressure, 2) daily tasks, 3) social robot experiences, and 4) the features a social robot should have to gather requirements. The experiment failed due to work pressure at the healthcare organization. The survey resulted in 181 respondents. The results suggest that tasks such as reminders, setting alarms and physiotherapy have a great potential to help the healthcare professional in reducing their work pressure and tasks, and the elderly to be able to stay living longer at their own home.

Social Robotics is becoming more relevant for the healthcare sector as an increasing amount of research and development is invested by researchers and practice. One research area where additional research would help the acceptation and adoption of social robots is intramural care where people with dementia live. The current body of knowledge on this topic can be described as nascent. In this study, we add to the body of knowledge regarding the design and enactment of social robots like the one used in this study, the Tessa robot, with the goal to improve acceptation and adoption of social robots in dementia care. To do so, we conducted a case study at a healthcare organization, featuring semi-structured interviews, observations and talking mats. During this case study, an experiment was carried out in which a Tessa robot was used in intramural care with three clients suffering from dementia. The most important finding of this study is that for the robot to be accepted and effective it must be implemented properly in the existing healthcare processes, otherwise it might serve as a companion, but will not relieve the workload of healthcare workers.

Numerous statements and pamphlets indicate that governments should increase the transparency of ICTimplementations and algorithms in eGovernment services and should encourage democratic control. This paper presents research among civil servants, suppliers and experts who play a role in the automation of spatial policymaking and planning (e.g. environment, building, sound and CO2 regulation, mobility). The case is a major digitalisation programme of that spatial planning in the Netherlands. In this digital transition, the research assumption is that public and political values such as transparency, legitimacy and (perceived) fairness are difficult to validate in the practice of the design process; policy makers tend to lose sight of the algorithms and decision trees designed during the ICT -implementation of eGovernment services. This situation would implicate a power shift towards the system level bureaucrat. i.e., the digitized execution of laws and regulations, thereby threatening democratic control. This also sets the stage for anxiety towards ICT projects and digital bureaucracies. We have investigated perceptions about ‘validation dark spots’ in the design process of the national planning platform that create unintended shifts in decision power in the context of the legal planning process. To identify these validation dark spots, 22 stakeholders were interviewed. The results partially confirm the assumption. Based on the collected data, nine validation dark spots are identified that require more attention and research.

This paper proposes a framework for assessing the sustainability of online retailers. By adhering to the logic of the value chain, the framework captures all steps from procurement to shipping of products and handling product returns that typically occur in e-commerce. The framework is then applied to explore the sustainability of 227 Swiss online shops through a clustering approach. Core elements of the framework are dummified and condensed to 20 features using an autoencoderbased neural network. K-means clustering is used to identify three sustainability clusters that are visualised in the latent space. One-way ANOVA and chi-square analyses of the three-cluster solution indicate that the identified clusters are distinct across most elements of the proposed framework. These preliminary results hold a variety of future research avenues.

Published: September 2021

Public sector organizations produce and process increasing amounts of data and the number of research and initiatives on open data is also increasing. Defining the true value of OGD is challenging without knowing how it impacts society and its economy. While the analysis of the economic benefits of open data is one way to describe the effect of government openness, the impact of open data is measured also in social and political context. Feedback mechanisms that are currently used are mostly surveys, while the number of OGD use cases is increasing. This paper proposes a preliminary model for research on assessing impact areas of OGD in an automated manner by using text mining techniques on existing use cases.
Investigation of the end bearing load in pile group model in dry soil under horizontal excitation
Authors: Fattah Mohammed Y. , Karim Hussein H. , Al-Recaby Makki K. M.
Published: September 2021

A series of 94 laboratory tests were conducted to measure the response of pile foundation when subjected to dynamic loads. Eight tests were conducted on single pile in dry soil at relative density 30 % (loose) and 50 % (medium); 66 tests on group of piles with different spacings and patterns. All tests were carried out under operating frequencies 0.5, 1 and 2 Hz under horizontal shaking. All tests were achieved with one embedment ratio (L/d = 30). These tests were grouped in three different numbers of piles; 2 piles in row and line patterns, 3 piles and 4 piles; and three pile spacing ratios (s/d = 3, 4 and 5).
The results of dry soil indicating the mechanism of dynamic response of piles and soil subjected to dynamic horizontal shaking include the variation and distribution of acceleration with time in different states of soil in addition to the vertical and horizontal displacements, end-bearing load, peak acceleration and the peak velocity of foundation.
It was concluded that for a dry soil bed, the acceleration amplitudes increase with frequency for both soil relative densities (loose and medium) and different pile patterns
(number; single or group and different spacing ratios s/d). The maximum acceleration in the foundation is lower than in the soil bed for all operating shaking frequencies, pile spacing ratios and soil states. The decreasing of the maximum acceleration recorded in the foundation as compared to that in the soil bed is between 10-100 % for loose and medium state of soil, and the decrease in loose state is more than in medium state. This means that there is damping effect or attenuation of vibration waves. The amplitudes of recorded acceleration in the pile cap are much higher than in the soil bed for single pile and pile group with different pile spacing ratios, also these amplitudes are increasing with increase of shaking frequency and relative density of the soil.

Published: September 2021

The development of modern thermocatalytic technologies for processing oil and gas raw materials is one of the promising areas for the advancement of chemical production. New highly efficient catalytic systems with the required technical characteristics and long service life play an essential role in solving these issues. The paper focuses on obtaining propylene by selective propane dehydrogenation. In the course of the experiments, composite iron-containing catalysts were synthesized, in which the active component is iron oxide in combination with an inert carbon matrix. FAS activated carbon and carbon nanotubes were used as the matrix. As a result of the synthesis on the catalyst surface it was possible to obtain catalytic centers that transfer electrons by changing the degree of iron oxidation when converting the starting materials into the target reaction products. Findings of research show that the obtained iron-containing catalysts significantly increase the efficiency of the process in comparison with the efficiency of thermal cracking of propane. Thus, the Fe3+/FAS catalyst showed a conversion rate of the initial reagent of 68 % and a propylene selectivity of about 42 %. Further transition to catalytic systems based on singlelayer and double-layer carbon nanotubes modified with iron oxide (Fe3+/CNTI and Fe3+/CNTII) made it possible to obtain propane conversion up to 37--40 % with a decrease in propylene selectivity to 29--30 %. Studies of the service life of the synthesized catalytic systems and the possibility of their regeneration show that, with account for the regeneration, the activity of the catalysts and the main technical characteristics of the propane-to-propylene cracking process remain unchanged for 10 working cycles

Authors: Petrenko E.M. , Semenova V.A.
Published: September 2021

Lithium-thionyl chloride battery voltage is practically not changing during the discharge process and drops sharply being completely discharged. In this regard, the problem of non-destructive quality control of the chemical current sources (first of all, the discharge degree) before installation thereof in the equipment becomes of particular importance. Microcalorimetric studies make it possible to rather correctly determine the current source internal self-discharge rate, predict the LCCS shelf life and its performance term. However, the heat release absolute value in current sources with sufficient storability, i.e., with low self-discharge, is very small; therefore, it is necessary to use sensitive, stationary and large-sized equipment. This makes such diagnostics impossible when operating in the stand-alone conditions. The impedance spectroscopy method could be proposed to solve this problem. However, satisfactory results are only obtained in the 0--70 % residual capacitance range. Determination of residual capacitance in the 70--100 % range appears to be rather difficult due to the absence of noticeable alteration in the informative parameter within the limits of its absolute deviation from the mean value. In this regard, it looks advisable to use noise spectroscopy as a physically independent method in diagnosing the state of chemical current sources to expand the residual capacitance diagnostics range to the 70--100 % domain, as well as to increase reliability of the chemical current source diagnostic estimate in the range of 50--70 %. Results of the electrochemical noise measurement analysis confirm promising application of the noise spectroscopy method in estimating current state of the primary chemical current sources in their low discharge domains

One of the largest sources of heavy metal compounds entering the hydrosphere is galvanic production. Despite their high danger, chromium (VI) compounds are widely used in electroplating. Electrolytes based on chromium (VI) compounds are stable at all pH values and, if released into water, pose a serious problem for wastewater treatment plants. The purpose of this study was to assess the possibility of thermal and electrochemical preparation of solutions of complex coagulants-reducing agents based on titanium trichloride for wastewater treatment from chromium (VI) compounds. Findings of research show that the yield of titanium trichloride is practically independent of the production method, however, the process of electrochemical synthesis is much more stable, the reaction mixture is slightly heated, which has a positive effect on the storage time of the obtained reagent solutions. The study proves that in terms of their effectiveness, the samples of the complex coagulant-reducing agent are superior to individual reagents based on iron (II) compounds. Moreover, the use of complex reagents makes it possible to considerably intensify the processes of sedimentation and filtration of the resulting sludge, which allows us to significantly reduce the dimensions of the equipment and increase the economic efficiency of the water purification process as a whole

Orbital hematic cyst is characterized by cystic accumulation of hematogenous debris surrounded by a wall of fibrous tissue without an epithelial lining. It is a relatively uncommon benign cyst and occurs secondary to blunt trauma in most cases. We experienced a case of 53-year-old male who presented with proptosis of the left eye. A cystic lesion was found at the superolateral orbital rim of the patient. We report a case of orbital hematic cyst that was resected completely through the sub-brow approach.

Industrial revolution and fast deforestation in 20th century pushes the earth to face climate change. Climate change became one of the most important global environmental challenges of the 21st century. Besides other weather abnormalities it is potential threat to world food security as agriculture production is directly dependent on various weather parameters. Even a small alteration in climate, adversely affects agriculture by decreasing the production. Global temperatures have already increased by 0.70°C over the past century and prediction of more rise of temperature is there. Possible changes in temperature, precipitation and CO2 concentration are expected to significantly impact crop growth. India could experience a 40% decline in agricultural productivity by the 2080s. Various food grain crops are going to affect badly under the temperature rise situation. It has been projected that under the scenario of a 2.50°C to 4.90°C temperature rise, rice yields will drop by 32% to 40% and wheat yields by 41% to 52%. This paper summarized study related to climate change projections and its impact on production of various crops.

Published: September 2021

Background: Potato seed production with aeroponic technology can produce a large number of seeds, besides that it is also healthy because it uses plant seeds from tissue culture. However, how the quality of aeroponic seeds produced to become the next seed (growth capacity) has not been studied and scientifically informed. This research aimed to obtain the effect of aeroponic seed yields from the low and high plains based on their size on the growth and yield into advanced seeds. Potato seeds used were from the highland and lowland using aeroponic technology. Methods: This research was conducted in the highland (1000 m above sea level) from April to July 2017. Seeds were classified as S ≤ 1 mg, 1 ≤ Md ≤ 10 g and L ≥ 10 g. This research used a randomized block design with seven repetitions. The tried factors were as follows: 1. The origin of aeroponic seeds (A): A1 (lowland), A2 (highland); 2. The size of aeroponic seeds (U): U1 (S), U2 (M), U3 (L). Plant growth parameters included plant height, number of leaves and number of tubers. Result: The data obtained were analyzed using Duncan’s Multiple Range Test (DMRT) at the 5% level. Seeds of aeroponic yields of various sizes that are planted using drip irrigation have the potential to become advanced seeds. The L-size aeroponic seeds from the lowland produced an average of 5.9 tubers with an average weight of 68.4 g.

Published: September 2021

Background: The difference in degradation time on the formation of carotene’s derivative aromatic compounds [β-ionone and dihydroactinidiolide (dhA)] due to thermal degradation process of carotenes in crude carotenoid extract of carrot was studied. Methods: β-ionone and dhA formation and that of carotenes degradation during thermal degradation (T=140°C) was observed periodically for 4 h. The constant oxygen supply during degradation was maintained at approx. 7 L/h. Result: The formation of β-ionone and dhA accumulated significantly with increasing duration of the degradation process. The maximum formation of β-ionone and dhA could be estimated with the pattern of carotenes degradation. After 4 h of degradation, more than 80% carotene has degraded. It can be concluded that the degradation process of crude carotene extract from carrots at temperature of 140°C will result in a maximum carotene degradation process when the degradation process is carried out for 5 h.

Published: September 2021

Educational institutions strive to achieve their purposes mainly assessing students’ performance and abilities; they might use traditional types of assessment or they may be forced to apply electronic assessment in certain situations such as those dictated by the current spread of COVID-19 Pandemic. The current study aims at providing insights into the ways and levels of university students' evaluation of the electronic assessment during the global health crisis whether this evaluation is affected by certain demographic variables or not. A 29-item online questionnaire was developed and conducted by the researchers to survey a large sample of university population. A large number of the students (n=582) responded to the survey.  The study results show that the level of students’ evaluation of e-assessment is moderate. The researchers also find that an interaction between gender and faculty may influence students’ evaluation positively and negatively. The implications of the study suggest that educational institutions should consider all types of assessment mainly e-assessment to keep pace with all advancements and evade unexpected circumstances like pandemics.
