Chinglish: Unraveling the Cultural and Cognitive Pattern Differences in Cross-Linguistic Communication
Authors: Zhao Xiaofang , Jawing Esther , Liu Xiaoman
Published: September 2023

English, as a foreign language in China, is often influenced by the first language (L1), which is Chinese, giving rise to the phenomenon of Chinglish. Chinglish, a distinct English variety, significantly differs from standard English in various aspects. The prominent reason for these differences lies in the variance of culture and thinking patterns. Unfortunately, Chinglish impedes effective cross-cultural communication and hinders the advancement of English learners’ proficiency. This study aims to elucidate the current state and specific manifestations of Chinglish concerning vocabulary and syntax from the perspective of cultural and cognitive disparities. The research employs questionnaire surveys and material analysis methods to gather data. Preliminary analysis reveals the widespread prevalence of Chinglish during the English learning process, with the primary vocabulary errors being redundancy, improper word usage, and incorrect collocation. In terms of syntax, word order, tense, and voice are particularly discussed as problematic areas. This paper concludes with suggestions for avoiding Chinglish, aiming to enhance cross-cultural communication and elevate English proficiency levels among Chinese learners.

Published: September 2023

Purpose. To establish the features of yield formation and seed quality in switchgrass (Panicum virgatum L.) depending on its location on the plant – panicles of the 1st and 2nd tiers.
Methods. Laboratory, measuring and weighing, mathematical and statistical.
Results. There was no significant difference in the yield of cleaned seeds depending on the place of their formation. On average over four years, the yield of seeds from panicles of the first tier was 91.9% and from the second tier 90.6%. It was found out that in the Central Forest Steppe of Ukraine, the yield of switchgrass seeds significantly depended on both the growing conditions (year) and the panicle tier. On average over the years of research, significantly higher seed yield was formed on the panicle of the first tier of both varieties. It was 0.83 g on the panicle of the first tier in variety 'Cave-in-Rock' and 0.70 g in 'Sunburst'. On the panicle of the second tier, the productivity was significantly lower − by 0.35 and 0.31 g, respectively (LSD0.05 tier = 0.24), and was 0.48 g and 0.39 g per panicle. Any significant difference based on varietal characteristics was not detected. The biggest influence on seed yield made cultivation conditions of the year (47.7%) followed by panicle layer (32.9%). The influence of other factors and their interaction was insignificant. The quality of the seed depended both on varietal characteristics and on the place of its formation on the plants. On average, over four years, the seed quality indicators - germination energy and germination – from panicles of the first tier were significantly higher in ‘Cave-in-Rock’, amounting 33% and 34%, respectively. In the second tier, on the contrary, the indicators were higher in ‘Sunburst’ and amounted to 35% (LSD0.05 variety = 0.3%).
Conclusions. The yield and quality of switchgrass seeds was significantly affected by cultivation conditions of the year, varietal characteristics and the place of grain formation. The highest yield was formed on the panicle of the first tier in both varieties. 'Cave-in-Rock' formed significantly higher seed yield on the panicles of all tiers, compared to 'Sunburst'. A significantly higher seed germination and germination energy was obtained with the seeds harvested from the panicles of the first tier.

Published: September 2023

Purpose. To determine the yield and quality of different kidney bean varieties.
Methods. Field (determination of yield); laboratory (determination of the 1000 kernel weight and the protein and starch content in grain); mathematical and statistical analysis.
Results. On average, over two years of research, the highest yield (3.31 t/ha) was obtained in ‘Podolianka’ variety, while the lowest (1.02 t/ha) in ‘Dvadesiatytsia’. The yield at the level of 2.04–2.72 t/ha was obtained in varieties ‘Bilosnizhka’, ‘Pervomaiska’, ‘Oniks’, ‘Bukovynka’, ‘Mavka’, ‘Zhuravka’, and ‘Shchedra’. However, the yield was 22–62% lower compared to ‘Podolianka’ variety. The yield of the rest studied varieties varied from 1.29 to 1.81 t/ha. The highest 1000 kernel weight was obtained in ‘Podolianka’ and ‘Bukovynka’ varieties (230 and 245 g, respectively). This indicator was the lowest in ‘Zlatko’ and ‘Dvadesiatytsia’, 106 and 113 g, respectively. In the rest of studied varieties, 1000 kernel weight ranged between 123 and 210 g. The highest protein content of 30.2% was obtained in ‘Onyx’ variety. In ‘Zhuravka’ and ‘Podolianka’ varieties, the protein content was 27.0–27.2%. The lowest protein content of 19.4% was obtained in the grain of ‘Dvadesiatytsia' variety. In the rest of varieties, this indicator was 20.0–26.0%. At the same time, the stability index of protein content formation was high – 0.94–0.99. The protein content of kidney bean grains in 2022 was higher (19.7–30.4%) and in 2021 lower (19.1–30.0%). The content of starch in kidney bean grains changed inversely proportional to the protein content, i.e., in 2021, this indicator was higher and in 2022 lower. However, the starch content changed little depending on the year, as the stability index was high and ranged between 0.97 and 0.99.
Conclusions. The highest yield of 3.10–3.52 t/ha was obtained in ‘Podolianka’ variety. At the same time, the content of protein and starch in the grain was 26.4–28.0 and 40.5–41.5%, respectively; the 1000 kernel weight was 219–241 g. The highest protein content was in ‘Onyx’ variety – 30.0–30.4% for the yield of 2.00–2.64 t/ha. At the same time, 1000-kernel weight in this variety was 146–164 g. Kidney bean varieties react differently to weather conditions as the yield stability index varied between 0.52 and 0.88. However, the stability index for the formation of protein content was high – 0.94–0.99.

Baryogenesis
Authors: Fong Chee Sheng
Published: September 2023

The standard model of particle physics describes matter and antimatter as coming from the same fields and this fact has been confirmed experimentally. It is then curious that the observable universe is made of matter and not antimatter. We will first discuss the evidence that we live in a matter-dominated (or matter-antimatter asymmetric) Universe and then proceed to discuss if this can be explained according to our current understanding of the cosmology and particle physics. We will argue that an important process known as baryogenesis to generate a cosmic matter-antimatter asymmetry had to occur before the Universe was a few second old. Then, we will discuss the necessary ingredients for a successful baryogenesis and point out that the current model contains all the ingredients but not in a sufficient amount. Finally, we will discuss possible extensions to the current model which allow successful baryogenesis and how they can be tested experimentally. Interestingly, they might also be connected to other open puzzles in the fundamental physics, like the tiny neutrino mass.

Authors: Munas Fathima Rehana , Kok Hwa Yu , Yusoff Norwahida , Muzathik Abdul Majeed , Ismail Mohd Azmi
Published: September 2023

Aircraft icing remains a key aviation hazard as the global fleet of aircraft in various sectors continues to expand, posing a serious threat to flight safety. As previously stated, the growth of this type of aircraft has been accompanied by an increase in noise levels, and aircraft is reportedly the second most bothersome noise source after traffic. However, integrating an acoustic liner with anti-icing techniques on the leading edge of a nacelle would not efficiently eliminate forward radiated noise and improve the thermal performance of the anti-icing system. Hence, it is of the utmost importance to research the integration of ice protection and noise abatement systems for aircraft applications. This review discusses the integration of ice accretion and noise abatement systems in aircraft applications. The prominence of this review is to explain significant features such as ice protection systems, Computational Fluid Dynamics in ice protection, noise abatement systems, and the integration of ice protection systems and noise abatement systems wherever they are described.

Authors: Zulaikah Siti , Juliansyah Arif , Rouf Hasan Muhammad Fathur , Iswanto Bambang Heru , Mariyanto Mariyanto , Tanjung Ardyanto , Bijaksana Satria , Hirt Ann Marie
Published: September 2023

Sumbawa’s Kuris River is one of the rivers contaminated by the island’s traditional gold mine. In order to detect contaminant levels, we examine the magnetic susceptibility, HCN levels, and the heavy metal contents on the river’s surface sediment. Environmental pollution has been widely assessed using a combination of magnetic properties and geochemical analysis. The goals of this research are to discover how magnetic susceptibility (χ) can be used as a first-order proxy for pollution. The relation between susceptibility and HCN is of particular interest, as this is a major contaminant associated with gold mining. The surface sediment samples were collected at ten different locations along the rivers. The magnetic susceptibility was determined using the Bartington MS2B, and the hydrogen cyanide (HCN) concentration was determined using Argentometric titration. The element content was determined by an Atomic Absorption Spectrometer (AAS). The low-frequency magnetic susceptibility (χlf) ranges from 71 to 115×10-8 m3/kg, with an average of 97×10-8 m3/kg, and the χfd(%) analysis ranges from 2% to 4%. The presence of spherical iron oxides, which are indicative of combustion byproducts, was also confirmed by SEM. The samples have low magnetic susceptibility but high levels of Hg and HCN. AAS results showed high Fe, Zn, and Cu concentrations in river sediments, with more variable concentrations of Hg, Mn, As, Cr, and Au. Because Fe, Cu, As, Hg, and HCN have a significant Pearson’s correlation with χfd(%), this parameter can be a useful indicator for contamination caused by gold mining waste.
Recognition of Fruit Types from Striking and Flicking Sounds
Authors: Phoophuangpairoj Rong
Published: September 2023

This paper proposes a method to recognize fruits whose quality, including their ripeness, grades, brix values, and flesh characteristics, cannot be determined visually from their skin but from striking and flicking sounds. Four fruit types consisting of durians, watermelons, guavas, and pineapples were studied in this research. In recognition of fruit types, preprocessing removes the non-striking/non-flicking parts from the striking and flicking sounds. Then the sequences of frequency domain acoustic features containing 13 Mel Frequency Cepstral Coefficients (MFCCs) and their 13 first- and 13 second-order derivatives were extracted from striking and flicking sounds. The sequences were used to create the Hidden Markov Models (HMMs). The HMM acoustic models, dictionary, and grammar were incorporated to recognize striking and flicking sounds. When testing the striking and flicking sounds obtained from the fruits used to create the training set but were collected at different times, the recognition accuracy using 1 through 5 strikes/flicks was 98.48%, 98.91%, 99.13%, 98.91%, and 99.57%, respectively. For an unknown test set, of which the sounds obtained from the fruits that were not used to create the training set, the recognition accuracy using 1 through 5 strikes/flicks were 95.23%, 96.82%, 96.82%, 97.05%, and 96.59%, respectively. The results also revealed that the proposed method could accurately distinguish the striking sounds of durians from the flicking sounds of watermelons, guavas, and pineapples.

Authors: Wang Daoping
Published: September 2023

The effects of climate change are increasingly transforming natural environments, threatening human living and socioeconomic developments. While mitigation action remains a priority, government efforts must also focus on helping people adapt to today’s climate impacts. Emerging digital technologies, which provide more efficient, rapid, and reliable risk monitoring and forecasting and enable better decision-making, can play a critical role to this end. This study develops policy recommendations for the utilization of digital tools to enhance climate change adaptation in China. This article first identifies China's primary climate change adaptation challenges, followed by an examination of successful digital solutions from countries outside of China. Successful application cases include using advanced machine learning models to develop more accurate rainfall predictions and applying digital twin systems to manage urban sewers in real time. These solutions are then evaluated in the Chinese context, leading to the formation of policy recommendations to advance similar initiatives.

Published: September 2023

Purpose: This research aims to assess the environmental and health consequences of crude oil exploration in the Niger Delta, focusing on the emission of greenhouse gases and air pollutants and their impacts on public health.
Methodology: Literature search was done independently by the authors. After searching for articles on the identified databases, other sources of available and useful data on the subject such as the print press, student’s thesis and dissertation among others were sourced by hand search to augmented resources from the electronic databases.The Literature search was based on the careful evaluation of key words in the title and abstract of identified studies.
Findings: The synthesis of available literature revealed significant insights into the environmental and health repercussions of crude oil exploration in the Niger Delta. The impact of gas flaring emerged as a major concern, leading to the release of pollutants like carbon dioxide, methane, and volatile organic compounds. These emissions contribute to elevated atmospheric temperatures, greenhouse gas concentrations, and the formation of acid rain, exacerbating global warming and disease transmission. The exposed population experiences a range of health problems including chronic respiratory diseases, cardiovascular abnormalities, altered blood parameters, and an increased risk of non-communicable diseases such as hypertension and diabetes. Prolonged exposure to pollutants from oil exploration is linked to disrupted sleep patterns, elevated stress levels, and neurophysiological disturbances, further contributing to adverse health outcomes.
Unique contribution to theory, practice, and policy: This study advances existing knowledge by providing a comprehensive analysis of the multifaceted interplay between crude oil exploration, environmental degradation, and human health in the Niger Delta region. The research offers a substantial contribution to theoretical understanding by illuminating the intricate relationship between anthropogenic activities, environmental factors, and health outcomes. Moreover, the study provides practical implications by proposing a series of recommendations aimed at mitigating the negative impacts of oil exploration. These recommendations advocate for stricter regulations on emissions, increased monitoring and enforcement, adoption of cleaner technologies, community engagement, and investment in healthcare and environmental remediation. The findings inform policy formulation by supplying evidence-based insights to develop robust regulations and interventions that promote sustainable development, protect public health, and safeguard the environment for future generations.

The project undertaken is extremely engrossed on Credit Card Fraud Detection. The rise within the number of card transactions in every sector had been resulting in many fraudulent transactions. The aim is to get goods without paying, or to get unauthorized funds from an account. This way of implementing the efficient method of detecting the fraud credit cards has been the most crucial for every bank which provides the credit cards in order to reduce their loses. The crucial & foremost challenge in construction of business is that neither the card holder nor the card has to be present when some purchase is being made. So, this makes it impossible for the merchant to verify whether the customer is an authentic cardholder or not. With the proposed scheme, the accuracy of detecting the fraudulent transactions is improvised using random forest algorithm. The Classification process of random forest algorithm is to investigate data set and user current dataset. At last, the result obtained is further gone for optimizing the accuracy. And also, this is chosen to be the best as this technique’s performance is best in accuracy, precision and thus can be easily evaluated and supported

An experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2021 to February 2022 to study the incidence and ecofriendly Management of Capsicum fruit borer. The experiment consists of control measures and plant extract. The experiment was laid out in Randomized Complete Block Design replicated with four times. For this study having six treatment, viz. Treatment T1: Sanitation + Netting; T2: Field sanitation + Mulching of soil; T3: Field sanitation + Spinosad (Taccer)@ 0.5ml/L of water at the 7 days intervals; T4: Mulching + leaf extract of neem at the 7 days intervals; T5: Field sanitation + Neem oil @ 2.0 ml/L of water with detergent at the 7 days intervals; T6 : Control were included in this study. were used. Results showed that the significant variations were observed among seven treatments, it was observed that treatment T3 (Field sanitation + Spinosad at the 7 days intervals at the 7 days intervals) was the most effective treatment for reducing insect pest’s infestation at total growing stages. The lowest performance observed in T6 (Control) was followed by T1 (Sanitation + Netting) treatment. The highest total yield hectare-1 was found from P2 (28.43 ton), while the lowest yield hectare-1 was found from T6 (24.54 ton) treatment. The yield of capsicum was highly significant (p=0.05), very strong and negatively correlated with infested fruit yield (t/ha) i.e., the total yield of capsicum increased with the infested fruit yield (t/ha) decreased

Published: September 2023

Retaining high quality school-based agricultural education teachers is a growing concern across the United States. This study focused on mid-career agricultural education teachers’ perceptions of job stress, burnout, job satisfaction, and professional development needs related to National Quality Program Standards for Secondary Agriculture Education (The National Council for Agricultural Education, 2009). The target population for this study was participants in the 2013 NAAE eXcellence in Leadership for Retention (XLR8) professional development program. Overall, XLR8 participants indicated the highest levels of job stress related to Standard 2 – Experiential Learning and Standard 7 – Program Planning and Evaluation. Participants were least stressed over Standard 6 – Certified Agriculture Teachers and Professional Growth, which also ranked lowest in terms of desired professional development. The most sought-after area of professional development included Standard 2 – Experiential Learning and Standard 1 – Program Planning and Instruction. Findings suggest XLR8 participants experience “moderate” levels of burnout in each of three categories measured by the Maslach Burnout Inventory for Educators, however are generally satisfied with their job.

Published: September 2023

The international rescue response to natural hazards, which has frequently drawn the attention of the international community, is a very important part of the international humanitarian assistance system. This paper focuses on the international rescue response mechanism, which is under the United Nations (UN) framework, and trends in its development. Referencing the international rescue response mechanism, this paper analyzes the overall characteristics of the humanitarian response mechanism under the UN framework, and its main components, basic procedures, quality guarantee, and support of the international rescue response mechanism. In view of the international rescue development, this paper reviews the development history and the strategic plan from 2021 to 2026. From the authors’ point of view, in the next development period, the international rescue community should pay more attention on building Urban Search and Rescue team’s capacity at different levels and standards, ready to respond to different kinds of disasters with flexible modules, establishing deeper and more extensive partnerships during the preparedness phase. We hope to provide a foundation for broader and deeper discussions in this field.

Makana Local Municipality is located in the Eastern Cape Province of South Africa. The area is water-scarce and has been undergoing aridification in recent years, ie, there has been a 7-year long drought. At the same time, there has been a breakdown in provision of municipal services, such as drinking water, to the population since at least 2008. Microbial water quality has been a result of this, and monitoring has been a challenge. Given the drought and the problems with drinking water delivery, it was necessary to conduct this study to investigate the microbial quality of alternative water resources that the Makana population can use during the municipal water outage. The microbial water quality of alternative sources of drinking water in the Makana Local Municipality was examined using the H2S test kit and enumeration of the fecal coliforms. Storage of the collected water was examined for potential factors influencing the microbial water quality of the alternative sources of drinking water. The costs of the water provision from the most suitable alternative sources of potable water were calculated. There was a general correlation between the H2S test kit results and the fecal coliform concentrations, with the latter values ranging from <0 to 23 ± 7 colony-forming units/100 mL. The bottled water from two retail outlets was provided the best alternative source of potable/drinking water, which is microbially safe, for the Makana population. If the consumption of the drinking water from an alternative source takes place within 24 hours of collection, then the Fairview spring could also be used as a source of drinking water for Makana residents. The total cost per 1 L of drinking water from alternative sources was estimated to be from 1.51 to 5.81 ZAR. Therefore, the maximum cost of daily provision of drinking water from alternative sources would account for a maximum of 0.88 percent of the monthly household expenditure in the middle-to-high-income household. However, the daily costs of such provision of drinking water would account for a maximum of 8.11 percent of the monthly household expenditure in the low-income household. Provision of the drinking water from the alternative sources would have a minor impact of the monthly expenditure in the middle-to-high-income households. However, it is likely that the low-income households would not be able to sustain their water supply from alternative sources for longer than 24 hours, during a municipal outage in the drinking water supply.

Published: September 2023

Objective: After cardiovascular surgery, analgesic and sedative management in the intensive care unit (ICU) significantly affects short- and long-term outcomes of patients. This study aimed to clarify the impact of opioid reduction after acetaminophen administration on the length of intubation and rescue analgesic use after cardiovascular surgery.

Design: This was a case–control study.

Setting: This study was conducted in the ICU of a cardiovascular hospital.

Participants: Datasets of 556 post-cardiac surgery participants were collected; for final analyses, 266 participants were selected by propensity score matching. Equality between the intervention and comparison groups was ensured by calculating the standardized difference and difference test.

Interventions: The intervention group was treated with the multimodal analgesic sedation protocol.

Main outcome measure: The primary outcomes were the length of intubation and use of rescue analgesics.

Results: The intervention group demonstrated a decreased total opioid consumption (460.0 vs 580.0 mcg, effect size [ES] = –0.178), opioid administration time (1,130.0 vs 2,070.0 minutes, ES = –0.306), and sedative administration time (955.0 vs 1,577.0 minutes, ES = –0.354). Moreover, the protocol resulted in decreased duration of ventilation (990.0 vs 1,057.5 minutes, ES = –0.140) and reduced need for rescue analgesics, including flurbiprofen axetil (3.5 vs 34.5 percent, ES = –0.392) and loxoprofen sodium (19.5 vs 48.1 percent, ES = –0.284).

Conclusion: This study suggested that acetaminophen reduces opioid use and improves patient outcomes after cardiovascular surgery. Moreover, this research provides essential information for developing analgesic management strategies to reduce opioid consumption in patients after cardiovascular surgery.

Published: September 2023

Objectives: (1) To explore the characteristics of patients with opioid use disorder (OUD) maintained on either methadone or buprenorphine and (2) to determine the relative acceptability of integrating Tai Chi (TC) practice into an ongoing medication- assisted treatment for opioid use disorder (MOUD) program.

Design: Survey study.

Setting: The University of Arkansas for Medical Sciences Center for Addiction Services and Treatment Program.

Patients: 97 patients receiving MOUD treatment.

Main outcomes: Drug use history, treatment status, physical limitation, mental health, pain, and whether participants were interested in using TC to improve health outcomes.

Results: At least 30.9 percent of the sample reported moderate or higher level of limitation in performing rigorous physical activities, pain intensity, and pain interference. Between 37.1 and 61.5 percent of the sample reported various psychiatric symptoms. Methadone patients reported higher levels of physical limitations, especially in rigorous activities (p = .012), climbing several flights of stairs (p = .001), and walking more than a mile (p = .011), but similar levels of pain (ps = .664-.689) and psychiatric symptoms (ps = .262-.879) relative to buprenorphine patients. At least 40.2 percent of participants expressed moderate or higher level of interest in TC for improving health outcomes, with methadone patients more interested in participating to ease mental and sleep problems (p = .005) and improve physical fitness (p = .015) compared to buprenorphine patients.

Conclusions: High prevalence of physical limitation, pain, and psychiatric comorbidities were found in OUD patients. Since patients were interested in TC to improve their health outcomes, this low-cost intervention, if proven effective, can be integrated into ongoing MOUD programs to improve health in this population.
