Authors: Triyanto Triyanto
Published: December 2022

Speaking is not only about using language as a medium for delivering messages from the sender to the recipient, but also activities that involve brain work. In language activities, speakers who produce language orally are also producing language structures in their brains. This working paper aims to describe the pause phrases that often appear every time there is a public conversation. In addition, the presentation will also explain about language activities outwardly which are in line with the language process that is conceptualized in the mind, namely that every conversation sometimes stops because there are certain factors such as nervousness and other psychological conditions. The method used in this research is descriptive qualitative. The data in this study is the speaking word apa namanya in the verbal communication process produced by public speakers in conducting oral presentations in a scientific forum. Data analysis using taxonomic theory expressed by Leonard Bloomfield about linguistic behaviorism. Another theory is the outer structure and inner structure proposed by Noam Chomsky. Based on the analysis carried out, it was found that the word pause emerged from public speakers in scientific forums as a form of behavior that showed a reaction to the stimulus in the mind. These stimuli include nervousness, confusion, forgetfulness, and loss of concentration. The reaction appears with language behavior in the form of the emergence of a pause word to collect scattered focus and plan the next conversation. Based on these results, the speaking pause is used by public speakers to stay in control of the forum and to stay in the flow of the conversation.

For the most part, an understanding of metaphors in the Indonesian vocabulary is lacking when reading from just one point of view. The purpose of this study is, 1) to describe the metaphor of human activity in the Indonesian proverb; 2) to describe the metaphor of human activity in the Indonesian idiom; And 3) todescribe the metaphor of human activity in an Indonesian acronym. The method used in this study is qualitative descriptive. The data-collection techniques used are observation, good libel, and note-taking techniques. The theory used in this study is cognitive semantics. The results of this study are obtained by certain figures in the Indonesian vocabulary classified as metaphorical metaphors based on these types of metaphors that have 17 structural metaphors, 12 ontological metaphors, and 1 orientational metaphors. Based on this data, the most common metaphor is a structural metaphor found in both proverbs, idioms, and acronyms. Whereas the least encountered metaphor is an orientational type. The conclusion is that the metaphor in question has a general sense tendency to describe romance, the troubled life, and the brief response to events summarized on the theme life's dilemma.
A Review of End-of-Life care in the US: The conundrum in the absence of a guiding framework
Authors: Haseeb Usman
Published: December 2022

End-of-life care is a topic that many consider to be an uncomfortable one given its emotional, ethical, and legal complexities. The scope of legal death in the US was made clearer by the approval of the 1981 Uniform Determination of Death Act (UDDA). The act is completely adopted word for word by most US states, but there are states like Louisiana that adopted the UDDA with some included criteria for neurological death. It is important to note that the UDDA is a legal guide used to make legal and medical decisions rather than a law that must be followed completely. With the advancement of medical technology, individuals can be kept alive through a variety of medical interventions that sustain necessary physiological functions, such as breathing, in the absence of complete mental status or other basic functions considered to be fundamental to life These modalities at times blur the line between life and death, and disagreement exists on the technical definitions and applications of these terms. The result is an ethical gray area in which medical care can be provided, but the question of whether it should be provided remains. This article is meant to examine the ethical and societal implications of end-of-life care to an individual who- depending upon the definition- may be considered dead.
The impact of the COVID-19 pandemic on household income, consumption, and saving
Authors: Tafa Saranda , Bajrami Roberta , Shabani Gezim , Gashi Adelina
Published: December 2022

The primary factors that were initially assumed to contribute to a decline in household income were job losses, which affect the decrease in consumption (Organisation for Economic Co-operation and Development [OECD], 2020; Doerr & Gambacorta, 2020). Kosovo’s government has taken measures of social distancing, having a major impact on households such as the impact of dismissal due to the closure of businesses indefinitely. This regime is continuing from the different waves of COVID-19 variants and the family income as it goes and decreases. Therefore, the purpose of this study is to measure the impact of the COVID-19 pandemic on household income including household consumption and savings for the years 2020–2021. The study uses a quantitative research method, thus, for primary data collection, the online questionnaire is used. The latent variable in this paper is the COVID-19 pandemic, while the factors that determine the latent variable are: savings, job loss, family income before the pandemic, and consumption expenditures. The study concludes that COVID-19 has a negative and significant impact on family income, saving, job loss, and consumption expenditures. The results from the structural equation modeling (SEM) are significant and the likelihood ratio (LR) test is 47.46. These findings and those of Martin, Hallegatte, and Walsh (2020), Dossche, Kolndrekaj, and Slacalek (2021), and Bundervoet, Davalos, and Garcia (2021) are consistent.

Published: December 2022

Background: Dupilumab, a human monoclonal antibody, blocks the
shared receptor component for interleukins 4/13, key and central drivers
of type 2 inflammation. The LIBERTY ASTHMA TRAVERSE (NCT02134028)
open-label extension study demonstrated the long-term safety and
efficacy of dupilumab in patients ≥12 years who had participated in a
previous dupilumab asthma study. The safety profile was consistent with
that observed in the parent studies. Methods: This analysis
includes patients from phase 2b (NCT01854047) or phase 3 (QUEST;
NCT02414854) studies receiving high- or medium-dose inhaled
corticosteroids (ICS) at parent study baseline (PSBL) and enrolled in
TRAVERSE. We analyzed unadjusted annualized severe exacerbation rates,
change from PSBL in pre-bronchodilator (pre-BD) FEV
(L), asthma control (5-item asthma control questionnaire), and type 2
biomarkers in patients with type 2 asthma at baseline (blood eosinophils
≥150 cells/µL or fractional exhaled nitric oxide [FeNO] ≥25 ppb),
and subgroups defined by baseline blood eosinophils or FeNO.
Results: Of patients with type 2 asthma (n=1,666) in this
analysis, 891 (53.5%) were receiving high‑dose ICS at PSBL. In this
subgroup, unadjusted exacerbation rates for dupilumab vs placebo were
0.517 vs. 1.883 (phase 2b) and 0.571 vs. 1.300 (QUEST) over 52 weeks of
the parent study, and remained low throughout TRAVERSE (0.313–0.494).
Improvements in pre-BD FEV from PSBL were sustained
throughout TRAVERSE. Similar clinical efficacy was observed among
patients receiving medium-dose ICS at PSBL and biomarker subgroups.
Conclusions: Dupilumab showed sustained efficacy for up to 3
years in patients with uncontrolled, moderate-to-severe type 2 asthma on
high- or medium-dose ICS.

eDNA metabarcoding of avocado flowers: ‘Hass’ it got potential to survey arthropods in food production systems?
Authors: Kestel Joshua , Bateman Phil , Field David , White Nicole , Lines Rosemarie , Nevill Paul
Published: December 2022

In the face of global biodiversity declines, surveys of beneficial and
antagonistic arthropod diversity as well as the ecological services that
they provide are increasingly important in both natural and
agro-ecosystems. Conventional survey methods used to monitor these
communities often require extensive taxonomic expertise and are
time-intensive, potentially limiting their application in industries
such as agriculture, where arthropods often play a critical role in
productivity (e.g. pollinators, pests and predators). Environmental DNA
(eDNA) metabarcoding of a novel substrate, crop flowers, may offer an
accurate and high throughput alternative to aid in the detection managed
and unmanaged arthropod taxa (e.g. flower-visiting insects and potential
pollinators). Here, we compared the arthropod communities detected with
eDNA metabarcoding of flowers, from an agricultural species (Persea
americana - ‘Hass’ avocado), with two conventional survey techniques;
Digital Video Recording (DVR) devices and pan traps. In total, 80 eDNA
flower samples, 96 hours of DVRs and 48 pan trap samples were collected.
Across the three methods, 49 arthropod families were identified, of
which 12 were unique to the eDNA dataset. Alpha diversity levels did not
differ across the three survey methods although taxonomic composition
varied significantly, with only 12% of arthropod families found to be
common across all three methods. This study demonstrates that eDNA
metabarcoding of flowers to detect visiting arthropods, although in a
developmental stage, can complement traditional survey methods and
increase the diversity of taxa detected with implications for both
natural and agro-ecosystems.

Distribution and difference of medical resources among provinces in China
Authors: Yao deng wang , Yu RuiYang , Liu JuanJuan , Zhang Rong
Published: December 2022

Objective: To explore the distribution and difference of medical
resources among 31 provinces (municipalities) in China. Methods and
process: According to the health resource indicators of 31 provinces in
China Health Statistical Yearbook and China Statistical Yearbook, we
described and analyzed the total amount of medical and health resources,
per capita medical and health resources and high-quality medical
resources. By using cluster analysis and RSR (Rank-sum ratio)
comprehensive evaluation method, the difference of medical resources
among 31 provinces in China in 2020 was calculated, and the medical
resources of each province were classified, compared and analyzed to
describe the difference. Results and conclusions:(1) From the
perspective of total medical resources, the total medical resources in
the western region are far less than those in the eastern region,
showing a situation of “more in the east and less in the west”.
Provinces with large populations have large medical resources. Developed
cities such as Beijing and Shanghai have great advantages in medical and
health financial resources, while provinces in remote areas are
extremely backward in human, material and financial
resources.(2)Unbalanced distribution of high-quality medical resources:
tertiary hospitals are mainly concentrated in eastern and central China.
The number and scale of tertiary hospitals in western China are
obviously backward. China’s top 100 hospitals are mainly distributed in
the first tier and economically developed cities. Beijing, Shanghai and
Guangzhou accounted for half of the top 100 hospitals. Nearly half of
China’s provinces have no hospitals on the “Top 100” list. (3) Per
capita medical resources vary greatly. The per capita level of medical
resources in the three northeastern provinces (Inner Mongolia, Qinghai,
Sichuan, Beijing and Shanghai) is relatively high. The per capita level
of medical resources in Anhui, Jiangxi, Guangdong, Ningxia and other
provinces is low.
Effect of solid-state fermentation on select antinutrients and protein digestibility of cold-pressed and hexane-extracted canola meals
Authors: Li Chenghao , Shi Dai , Stone Andrea , Wanasundara Janitha , Tanaka Takuji , Nickerson Michael
Published: December 2022

In this study, the effects of solid-state fermentation (SSF), including
strain (Aspergillus niger NRRL 334 and A. oryzae NRRL
5590) and fermentation time (24, 48, and 72 h) on the nutritional value
of cold-pressed (CP) and hexane-extracted (HE) canola meals were
examined. SSF increased the protein content of both types of meals (from
~36 to ~40%) while reducing the oil
content of CP meals (from ~12 to 9%). There was a
significant reduction (~80%) in the phytic acid content
of both types of meals after fermentation using either fungi. Overall,
fermented samples showed a decrease in the total phenolic content from
2.7-3.1 to ~1.0 mg gallic acid equivalents (GAE)/g DM (a
~65% reduction), of which specifically the HE meal
fermented with A. niger sample had the greatest decrease from 3.1
to 0.6 mg GAE/g DM (~81% reduction). Seventy-two hours
of fermentation decreased the in vitro protein digestibility
(IVPD) of the meals. In contrast, a shorter fermentation time (24 h)
increased the IVPD as compared to the controls (from
~73% to 77-81%), with the exception of the CP meal
fermented with A. niger which had decreased IVPD at all
fermentation times. Overall, the changes indicate that SSF using
A. niger or A. oryzae can be useful to positively modify
the composition of different canola meals and improve their nutritional
value by significantly increasing the protein content, decreasing the
levels of antinutrients, while only slightly reducing IVPD.
On treatment options to improve the functionality of pea protein in emulsions
Authors: Wang Yong , Mathew Hannah , Kim Woojeong , Clayton Celeste , Selomulya Cordelia
Published: December 2022

Pea proteins are being widely investigated as a potential substitute for
animal proteins due to health benefits and sustainability concerns.
However, the limitations associated with functional properties of pea
protein such as low solubility, result in poorer overall performance and
render it less desirable for food applications such as plant-based milk,
cream, or meat products. Different methods have been extensively studied
to solve this issue. This review summarises recent and popular physical,
chemical, and biological treatments used to modify the functional
properties of pea proteins. The aim is to identify successful
treatments, gaps in knowledge, and presenting a comprehensive analysis
in methods to improve pea protein functionalities and the results after
these treatments. It was concluded that chemical modification is by far
the most effective in improving the solubility, emulsifying, and foaming
properties of pea proteins, followed by biological treatment. The
combination of different treatment methods, moreover, has shown some
degree of success and provides a wider scope to improve pea protein
functionalities, as a promising avenue for future studies.

Published: December 2022

Reliable short-time prediction of thermospheric mass density along the
satellite orbit is always essential but challenging for the operation of
Low-Earth orbit (LEO) satellites. In this paper, three machine-learning
prediction algorithms are investigated, including the Bidirectional Long
Short-Term Memory (Bi-LSTM), the Transformer, and the Light Gradient
Boosting Machine (LightGBM) ensemble model of the above models. We use
satellite data from CHAMP, GOCE, and SWARM-C to evaluate the robustness
and accuracy of different density variations. The comparison
demonstrates that all models achieve compelling predictions and are much
better than NRLMSISE-00. The LightGBM ensemble model (LE-model)
consistently outperforms others in accuracy and stability. Furthermore,
when the obtained density data from the newly launched satellites are
limited, the trained LE-model can provide a valid prediction for the new
satellite orbit by transfer learning. This study offers a promising
insight into the short-time prediction of thermospheric mass density
using ensemble-transfer learning and may be advantageous to future
research on space whether.
Volume Transport Estimation of the Kuroshio Extension based on Subsurface Mooring Array and Satellite Altimetry
Authors: Guo Haihong , Chen Zhaohui , Yang Haiyuan , Long Yu , Zhu Ruichen , Zhang Yue-Qi , Jing Zhao
Published: December 2022

The vertical structure of the Kuroshio Extension (KE) is investigated
using velocity measurements from a subsurface mooring array. Mode
decomposition based on climatological Temperature/Salinity (T/S) data
shows that the barotropic and first baroclinic normal modes dominate the
vertical structure of the zonal flow in the KE. This structure is also
well described by the leading mode of Empirical Orthogonal Functions
(EOFs) that contains the first two vertical normal modes. Further
analysis demonstrates that the projection coefficient of the mooring
velocity onto the summed vertical mode could be well represented by the
surface geostrophic velocity. Therefore, we propose a dynamic method
that relates the surface geostrophic flow and the vertical structure of
the zonal flow. The applicability of this method is verified with both
reanalysis datasets and estimation from hydrographic data. The findings
implicate that the KE transport can be well reproduced by surface
geostrophic flow and climatological T/S data only.
Exploring the Influence of Summer Temperature on Human Mobility during the COVID-19 Pandemic in the San Francisco Bay Area
Authors: Ly Amina , Davenport Frances V. , Diffenbaugh Noah S.
Published: December 2022

Heat related illnesses are one of the leading causes of weather-related
mortality in the United States, and heat extremes continue to increase
in frequency and duration. Public health interventions include
population mobility, including travel to central cooling centers or
wellness checks on vulnerable populations. Using anonymized cellphone
data from Safegraph’s neighborhood patterns dataset and gridded
temperature data from gridMET, we explored the mobility-temperature
relationship in the San Francisco Bay Area at fine spatial and temporal
scale. We leveraged spatial variability in median income and temporal
variability in COVID-19 related policies across two summers (2020-2021)
to analyze their influence on the mobility-temperature relationship. We
completed quantile regressions for a dataset stratified by income and
year. We found that mobility increased at a higher rate with higher
temperatures in 2020 than 2021. However, in 2021, the relationship
reversed for several wealthier income groups, where mobility decreased
with higher temperatures. We then augmented the analysis and calculated
a panel regression with fixed effects to characterize the
mobility-temperature relationship while controlling for temporal and
spatial variability. This analysis suggested that all areas exhibited
lower mobility with higher summer temperatures. However, similar to the
results of the quantile regression, the rate of decrease in mobility in
response to high temperature was significantly greater among the
wealthiest census block groups compared with the least wealthy. Given
the fundamental difference in the mobility response to temperature
across income groups, our results are relevant for heat mitigation
efforts in highly populated regions in current and future climate
conditions.

Published: December 2022

Hensikten med denne studien er å bidra med mer kunnskap om kommunikasjon mellom lærer og elever under arbeid med matematikkoppgaver som innebærer matematisk resonnering. Datamaterialet er videoopptak av matematikkundervisning i to klasserom på mellomtrinnet. Vi startet analysen med å identifisere episoder der det foregikk resonneringsprosesser. Videre analyserte vi enkeltutsagn i episodene, før vi satte utsagnene sammen til kommunikasjonsmønster. Studien viser at kommunikasjonen mellom lærer og elev følger fire mønstre avhengig av om eleven har kommet fram til riktig svar, feil svar, ikke hadde kommet fram til noe svar, eller har et uferdig svar. Det viser seg at det bare er i de tilfellene hvor eleven har kommet fram til riktig svar, at læreren forsøker å utvide elevens resonnering. I studien identifiserte vi også noen lærergrep som så ut til å kunne stoppe elevens videre resonnering.
ENGLISH ABSTRACT
Communication patterns in work on mathematical reasoningThe purpose of this study is to contribute to more knowledge about communication between teacher and students during work on mathematics tasks that involve mathematical reasoning. The data material is video recordings of mathematics teaching in two classrooms in middle school. We started the analysis by identifying episodes that included reasoning processes. Further on, we analyzed the episodes utterance by utterance, before identifying some communication patterns. The study shows that the communication between teacher and student follows four patterns depending on whether the student suggest the correct answer, the wrong answer, no answer, or an unfinished answer. The study shows that it is only in cases where the student suggests the correct answer that the teacher tries to expand the student’s reasoning. We have also identified some teaching practices that seem to stop the student’s further reasoning.

Published: December 2022

Internet addiction disorder (IAD) is a global topic that increasingly attracts the attention of the wider public. The purpose of this paper is to research the current situation in the prevalence of both Internet addiction and problematic Internet use, which is the most common precursor to developing psychological disorders related to the relationship to the Internet and its elements. The initial hypotheses of this paper are that the Internet addiction disorder is more widespread and harmful than can be deduced from the attitude of society and health authorities towards it and that it calls for renewed theoretical and empirical research, which is the attitude shared by the scientific community. The results that we stated in the paper clearly show numerous mental and physical deficiencies and problems that are experimentally proven and presented in the paper. As a recommendation, we would point to increasing awareness of the dangers of excessive and problematic use of the Internet, offering healthy alternatives, promoting the culture of safe use of the Internet, as well as educating individuals on other self-control mechanisms. Attention should be constantly paid to dangers that realistically exist, and it should be permanently worked on this aspect of mental health of individuals, nations, and the global society.

Published: December 2022

The article considers the relationship between the cyber socialization engagement and the Dark Tetrad of personality (Machiavellianism, narcissism, psychopathy, and sadism). The cyber socialization engagement was understood, according to the author’s concept, as having constructive and destructive components. The study purpose was to identify correlation and deterministic relationships between indicators of the cyber socialization engagement and the Dark Tetrad among young university students. The sample included 424 students from Russian universities. For measurements, «The cyber socialization engagement questionnaire» and «The Short Dark Tetrad Scale» were used. It has been established that the relationship between the indicators of the cyber socialization engagement and the Dark Tetrad has a qualitatively heterogeneous character – from the complete absence of connections to mutual determination. The strongest mutual determination is associated with the everyday sadism: it increases the destructive engagement in cyber socialization, explaining 12% of the total variance, and the latter, in turn, increases the severity of sadism (10.5%). It is advisable to take into account the revealed connections between the general cyber socialization engagement and the Dark Tetrad of the personality when organizing psychological support for the socialization of students in the context of expanding social interactions carried out in cyberspace.
