Listening Anxiety in EFL learning in China: An Autoethnographic Study
Authors: Chenyang Zhang  , Ha Nguyen
Published: September 2022

Listening anxiety in English as a foreign language (EFL) learning will reduce Chinese language learners’ academic performance, particularly in a formal listening test. In order to explore the effects of listening anxiety on EFL learners and how they cope, this article seeks to investigate my personal narratives and experiences as the first author to explicate challenges and seek solutions. Thus, this article focuses on my exploration of four vignettes, which identify crucial points in unraveling stories of how I could improve listening performance by reducing listening anxiety. This autoethnographic study is inspired by information processing (IP) theory and Schunk’s self-regulated learning (SRL) model. The former reveals how listening materials can be received by learners from an objective view. The latter, based on a subjective angle, highlights three aspects: motivational orientation, self-efficacy, and self-regulation, which collectively affect listening anxiety. Based on the analysis of my stories, findings suggest that anxiety can negatively impact EFL learners’ information processing abilities, thereby leading to poor listening performance. Findings also highlight a need to deal with listening anxiety, identifying and emphasizing three approaches, namely, a mastery-oriented goal, higher self-efficacy and appropriate self-regulation.
Measurement of Slope Stability on Stone Mines Around Pengsong Hills, West Lombok Area
Authors: Zuhdi Muhammad , Busyairi Ahmad
Published: September 2022

The slope stability angle of the surface landslide stability depends on the friction coefficient between the rock particles in the area. Measurement of slope stability is very useful for the safety of miners in mining areas. Measurement of slope stability is based on the friction coefficient. Measurements are made with a friction coefficient measuring instrument that has been designed and tested. Rock samples were taken at 3 rock mines around Mount Pengsong in West Lombok Regency. The measurement of the friction coefficient was carried out at the Physics Laboratory of the University of Mataram. The measurement results of the friction coefficient are then converted into slope stability angles. The results show that the slope stability angle in the mountains around the rock quarry around Mount Pengsong has a maximum value 5,71 degree of dry sample and 81,0 degree of moisture sample.
The Oral Artist and Oppositional Politics in Wole Soyinka’s Death and the King’s Horseman and Denja Abdullahi’s Mairogo
Authors: Bolajoko Aliyu Saeedat
Published: September 2022

In the context of modern societies, criticism of political leadership is located within the framework of formalized, democratized organizations, movements, and rights groups. These are modern paradigms within which dissenting factions of society express contradictory perspectives of the policies, actions or inactions of the leadership. This article examines the role of the social critic which oral artists played in traditional African societies in two selected literary works: Wole Soyinka’s Death and the King’s Horseman (1975) (a play) and Denja Abdullahi’s Mairogo (2009) (a dramatic poem). It also investigates how the symbolism-rich oral aesthetics aid the criticism. This essay regards the role of the oral artist in the society as a viable model of opposition which can be synthesized with aspects of the modern model. This would produce an effective medium for the expression of opinions and dissents against constituted authorities in postcolonial African societies. This exploration is crucial as postcolonial African states continue to grapple with the challenges of stabilizing their polity within a western framework which breeds factional rivalries and conflict between competing parties. This article concludes that re-thinking and merging traditional and modern paradigms of opposition discourse is fundamental to postcolonial African states attaining the needed environment crucial to their socio-political and economic development.

Published: September 2022

Introduction: After the initial COVID-19 outbreaks, caused by the SARS-CoV-2 virus, prolonged multiple post-infectious symptoms have continued to develop. Those who initially recovered from SARS-CoV-2 virus continue to experience a worsening life quality and a delayed return to work, which leads to great burden on the health care system. Up to date research reveals that psychiatric illness is both a risk factor for, and consequence of, COVID-19. The aim of this study is to describe the psychoneurotic symptoms among COVID infected patients. Patients and methods: A case series study of 101 patients infected with COVID virus of different severity of the disease in Tikrit city during 2020-2022. The patients were followed for 3 months. Information regarding age, gender other diseases, signs and symptoms, and psychoneurotic symptoms also were documented. Lung involvement percentage was assessed by CT. The SPO2% was reported for the patient at resting sitting position. The blood fasting sugar was tested; for all patients diastolic and systolic blood pressure were examined. Results: The reported cases with neuropsychiatric symptoms was 101. Case sleeplessness was reported among 60 (59%), tremor among 31(31%), and hallucination was reported among 10 (10%). The auditory hallucinations were reported among 4(40%), olfactory hallucinations reported among 5(50%), and visual hallucinations among 1(10%). Males were more affected than females regarding hallucinations 7(70%), and 3(30%) respectively, and tremor 17(54.8%), 14(45.2%). Sleeplessness was higher among females than males, 33(55%), 27(45%) respectively. The age groups 21-30 years and 61 years had the highest percentages of hallucination 3(30%), 3(30%), while age group 31-40 years had the higher percentage of sleeplessness 16(26.7%) and tremor was high among those aged 61 years, 11(35.5%). These relations were statistically significant. Conclusions: Neuropsychiatric symptoms were reported as follows; sleeplessness, tremor, and hallucination. Hallucinations mainly affected males, while tremor and sleeplessness mainly occured in females. The patients who had hallucinations had high lung involvement measured by CT of the chest. The patients eho had hyperglycemia had higher percentages of sleeplessness, and hallucinations. COVID 19 vaccinated persons had lower percentages of sleeplessness, hallucinations and tremor.

Published: September 2022

Background: Obesity is a common health problem among females in reproductive age. Obesity is associated with fetal and maternal complications. The aim of this study is to assess the knowledge, attitude and practice of pregnant women regarding obesity and its negative impact on maternal and fetal health. Methods: This study was conducted among 218 pregnant women who attended one primary care center in Abha City, KSA during 2018. The participants were interviewed during their visit to the antenatal clinic using a valid questionnaire which included many questions exploring the knowledge, attitude and practice regarding obesity during pregnancy. Data were entered and analyzed through SPSS. Relevant statistical tests were used accordingly, p-values were considered significant if less than 5%. Results: The prevalence rates of overweight and obesity were 37.6% and 24% respectively; more than half of the participants did not know the expected average weight increase during pregnancy and more than half were unable to classify their actual weight correctly. Knowledge regarding harmful effect of obesity on maternal and fetal health during pregnancy was poor. Pregnant women also have false beliefs about dietary habits and physical activities which may lead to gaining of extra weight during pregnancy and worsen the outcomes. Conclusion: The prevalence rates of overweight and obesity among many pregnant women were high. Knowledge related to obesity and its maternal and fetal risk were inadequate. False beliefs regarding lifestyle during pregnancy were evident. A preconception structured health education program to upgrade knowledge, change attitude, improve practice and to correct misbeliefs regarding obesity during pregnancy, is mandatory.

Osteoid osteoma of the proximal femur: A case report
Authors: Bughamar Ameena Khalid , Alaazmi Noora Hamad , Alkhalifa Fahad
Published: September 2022

Background : Osteoid osteoma “OO” is a benign bone tumor that has a potential to become malignant. It can affect people of all ages, but is most commonly seen in children and young adults. It commonly involves long bones such as femur and tibia. Patients often present with pain that is worse at night and relieved by non-steroidal anti-inflammatory drugs (NSAIDs). Osteoid osteoma can be diagnosed by imaging studies such as X-rays, a Computed tomography (CT ) scan and MRI as it classically consists of a central vascularized nidus that represents the neoplastic tissue which can be identified on a CT scan. Many different options are being used in the management of osteoid osteoma ranging from analgesics and physiotherapy to surgical intervention if the conservative management failed to relieve the pain. Case report: We are presenting a case of a 12 year old male with Proximal femoral OO who was managed conservatively in the beginning and then treated using X-Ray Guided percutaneous Drilling of the lesion with good postoperative clinical outcome. In this Report we are discussing the surgical steps as well as the prognosis compared to other treatment options. Conclusion: A delay of the diagnosis can occur due to the majority of differential diagnoses and the difficult interpretation of the diagnostic imaging, so a high clinical suspicion and early interventions using more advanced imaging modalities allows earlier diagnosis of ‘’OO’’ and therefore quicker treatment and relief of patient symptoms. Keywords: “OO” osteiod osteoma . “NSAIDS” by non-steroidal anti-inflammatory drugs. “CT” Computed tomography . “MRI” Magnetic resonance imaging.

Published: September 2022

Today mobility is a key feature in the new generation of Internet, which provides a set of custom services through numerous terminals. Smartphones, for example, are a tendency and almost mandatory for anyone living in an urban and modern context. Most developed cities have at least one shopping mall full of mobile device users. These shopping malls provide a number of stores, and people tend to have difficult in finding what they really need. This article proposes a solution called RecStore. RecStore is a recommendation model to assist customers in reaching what they consider relevant at malls. The recommendation model comprises user activities, 330 stores, 30 users and 3 baseline models. The precision, recall and f-measure improved at rates of 118%, 76% and 95% respectively in comparison to the second best model of each metric. Additionally, a mobile application — called InMap — was implemented based on our model RecStore.
Interactive Visualization of Trivariate Georeferenced Data
Authors: Magnus Pinheiro Tarsus , Esperança Claudio
Published: September 2022

This paper describes an online interactive thematic map for simultaneously visualizing up to three scalar variables and which supports data filtering, panning and zooming in levels of detail. The visual encoding of the map mixes the use of colors and textures as well as simple operations like border detection and intersection identification. The user experience is enhanced by means of queries posed through manipulation tools that produce instant visual feedback. This is possible through the high rendering rates achieved by the system through the use of GPU programming to assemble and manipulate previously rasterized tiles with location information recorded in the color space of pixels. This procedure allows the implementation of interactive animated actions and spatial data decomposition.
Técnicas para Detecção Dinâmica de Padrões na Passagem de Locks em Software DSMs
Authors: Seidel Cristina Bentes , Amorim Cláudio Luis de , Bianchini Ricardo
Published: September 2022

Sistemas de memória compartilhada distribuída, com coerência de dados mantida por software, têm se mostrado uma alternativa de baixo custo para programação no modelo de memória compartilhada. Entretanto, tais sistemas, denominados software DSMs, apresentam desempenho limitado devido principalmente ao grande overhead gerado pelo protocolo de coerência empregado. Nesse trabalho apresentamos técnicas para previsão dinâmica da passagem de locks entre os processadores. Essas técnicas podem ser utilizadas por software DSMs para sobrepor o overhead de comunicação e a computação útil. Mais especificamente, se um processador p pode prever o próximo processador p a adquirir a seção crítica em que ele se encontra, ele pode enviar antecipadamente suas mensagens de coerência a q e assim esconder a latência dessas mensagens com computação útil em q. Realizamos simulações com dois software DSMs diferentes e, para um conjunto de seis aplicações reais, mostramos que podemos estabelecer dinamicamente um pequeno conjunto de processadores que são os mais prováveis "próximos acquirers" de uma seção crítica. Os resultados obtidos em nossos experimentos indicam que as nossas técnicas alcançam taxas de acerto altas, variando de 60% a 97% do total de eventos de lock.
A Survey of Load Balancers in Modern Multi-Threading Systems
Authors: Kakulavarapu Prasad , Amaral José Nelson
Published: September 2022

Multithreaded architectures are a feasible approach to exploit parallelism in both regular and irregular applications. Today a large collection of multi-threading architectures with different threaded models, and implementation platforms are available. These architectures provide support for multithreading either at hardware level, with customized functional units, or at the software level, as emulators written in some high-level language. The later approach is usually prefered because of its favorable price tag, speed of development, and portability. In this article we review some of these architectures focusing in their capabilities to provide load balancing for irregular, data-parallel and recursive applications. The paper is anchored on a description of our own implementation of load balancers for EARTH - Efficient Architecture for Running Threads. Most of the multithreading architectures that we review are software emulations based on off-the-shelf hardware and compiler technologies.
NCESPARC+: A Multithreaded SPARC Architecture for the Multiplus Multiprocessor
Authors: Aude J. S. , Martins F. R. S. , Barbosa M. A. S. , Joao Jr. M. , Young M. T. , Pinto S. B.
Published: September 2022

NCESPARC+ is a SPARC V.8 architecture with hardware support to a variable number of thread contexts, which is under development for use within the framework of the Multiplus distributed shared-memory multiprocessor. It is expected to provide an efficient and automatic mechanism to hide the latency of busy-waiting synchronization loops, cache-coherence protocol and remote memory access operations within the Multiplus multiprocessor. NCESPARC+ performs context-switching in at most four processor cycles whenever there is an instruction cache miss, a data dependence in relation to the destination operand of a pending load instruction or a busy-waiting synchronization loop. Results of simulation experiments show the impact of some architectural parameters on the NCESPARC+ processor performance and demonstrate that the use of multiple thread contexts can effectively produce a much better utilization of the processor when long latency operations are performed.
A Taxonomy for Cache Memory Misses
Authors: Hamkalo José Luis , Cernuschi-Frías Bruno
Published: September 2022

One way to understand the causes of cache memory misses is to use a classification for them. Usually statistical models such as the 3C model are used to make the classification. In the present work a new definition for the 3C model: compulsory, capacity and conflict misses are given. The corresponding operational definitions are given, which are based on the use of the LRU stack distances. The proposed model is called a deterministic 3C model or D3C. The D3C model classifies the memory references in an individual way, conforming a taxonomy, and then it is possible to analyze when a memory reference belongs to a given category. Also the passage of a given memory reference from one category to another when some cache parameter is modified may be studied. The D3C model does not present anomalies such as negative conflict miss rales, as in the 3C model. Several patterns for memory access are theoretically analyzed for the 3C and D3C models, showing that the results given by the D3C model are intuitive and have easy interpretation. The 3C model underestimates the conftict misses and overestimates the capacity misses when compared with the D3C model. This difference comes from the references that hit in the cache under study and miss in a fully associative cache of the same size with LRU replacement policy. The amount of these references was measured using SPEC95 benchmarks in trace driven simulations. It is shown that high percent values are obtained for these references for usual cache configurations, and therefore these references have an important participation in the cache statistics.
A Proposal for a Parallel Programming Support for Multi-LAN platforms
Authors: Arantes Luciana , Folliot Bertil , Sato Liria M. , Sens Pierre
Published: September 2022

In the first part of this article, we present our proposal for a distributed shared memory system (DSM) for an interconnection of local-area networks (LANs). Our multi-LAN DSM will be composed of a set of per LAN lazy release consistency (LRC) memory model DSM systems. For controlling shared-memory updates, the LRC protocol of cach DSM will use the barrier-lock logical clocks, instead of the traditional per processor vector ones. This replacement provides modularity and scalability to some extent. The other enhancements to be added to the protocol aim the reduction of the number of messages and the volume of data exchanged between LANs for the sake of applications' performance. Data pre-fetching, simulation of a LAN-level cache and hierarchical execution of barriers are some of the strategies to be adopted. In the second part of the paper, we discuss the advantages of using the CPAR language for the development of parallel applications which run on top of shared-memory hierarchical platforms such as multi-LAN DSMs.

Authors: Yu Lingling , Liu Xiaolei , Shou Yunbi , Wang Bingcan
Published: September 2022

This paper explored the effects of practicing Qigong, a traditional Chinese fitness method which includes the imitation of the Five- animal exercise, on the psychological adjustment of college students with different personality types. Through the study of 220 college students aging from 19 to 22 a study of the responses made on the Eysenck Personality Questionnaire (EPQ) and Symptom check list-90 (SCL-90)] provided scientific data that supported the idea that Chinese traditional health preservation exercises can improve the mental health of college students. Specifically, after 12-week Qigong exercise, the total symptom index, interpersonal sensibility, obsessive-compulsive, paranoid-anxiety, depression, psychoticism and anger-hostility of the participants significantly differed from baseline. There were also significant differences in somatization and anxiety. In the female participants in the experimental group, there was a very significant difference in terms of anger-hostility, and there were also significant differences in terms of paranoid-anxiety and psychoticism, and in somatization, depression and the total symptom index. Further improvements are described.

Aim: We aimed to compare the efficacy and the safety of cisplatin plus 5-FU plus trastuzumab and mFOLFOX-6 plus trastuzumab at first-line treatment in HER2-positive metastatic gastric cancer.

Method: It was a retrospective observational monocentric study. Patients diagnosed with HER2-positive metastatic gastric adenocarcinoma between January 2013 and December 2020 in Dr AY Ankara Oncology TRH were screened. Patients treated at least one cycle of treatment with either CF-T or mFOLFOX-T were included. Survival outcomes and treatment compliance of patients were compared between groups.

Results: Of 52 patients, 55.8% (n=29) of patients were treated with CF-T, and 44.2% (n=23) with mFOLFOX-T. The median age at diagnosis was 60 years (IQR: 52-70) in the CF-T and 64 years (IQR: 59-70) in the mFOLFOX-T groups. De novo metastatic disease comprised 96.6% (n=28) of patients in the CF-T and 69.6% (n=16) in the mFOLFOX-T groups (p=0.016). Both IHC3+ and ISH positivity were observed 82.8% (n=24) of patients in the CF-T and 56.5% (n=13) in mFOLFOX-T groups (p=0.038). The mPFS was 10.4 months (95% CI 8.7-12.2) in the CF-T and 6.5 months (95% CI 5.5-7.6) in the mFOLFOX-T groups (p=0.532). The mOS was 12.2 months (95% CI 11.3-13.2) in the CF-T and 12.5 months (95% CI 9.8-15.5) in the mFOLFOX-T groups (p=0.974). No statistically significant difference regarding at least one dose reduction (31.0% vs 21.7%, p=0.453) and at least one dose delay (24.1% vs 21.7%, p=0.838) was observed between groups.

Conclusion: It was revealed that CF-T and mFOLFOX6-T had similar efficacy and tolerability in patients with HER2-positive metastatic gastric adenocarcinoma.

Google-car's Extended Mind
Authors: Gamboa Steven ,   Philosophy Documentation Center
Published: September 2022

While the value of the extended mind hypothesis for human cognition is disputed, this paper examines the explanatory utility of the extended mind framework in the domain of AI systems, specifically the Google self-driving car. I argue that the cognitive architecture of the Google-car is best explained as an instance of extended cognition. The argument for this claim begins with a description of the Google-car’s cognitive architecture, including the indispensable role of “prior maps” in its performance. I then argue that the hypothesis of extended cognition provides a better explanation of the Google-car’s performance than two rival, non-extended alternatives. Consideration of the Google-car also offers insight into whether driverless vehicles have achieved human-level competency in the cognitive skills required for driving, or instead remain “poor substitutes.”
La política desde abajo: Una aproximación etnográfica a las actitudes políticas de la ciudadanía vulnerable
Authors: Calvo Kerman , Martín Andrés
Published: September 2022

En este artículo se propone una etnografía de las actitudes hacia la política de aquellos ciudadanos que han sufrido de manera directa las consecuencias sociales y económicas de la crisis iniciada en 2008. Se corrige una limitación de los estudios basados en encuestas, que no suelen prestar la debida atención a las personas expuestas a formas avanzadas de marginalidad. Se ha observado e interactuado con, y entrevistado a personas usuarias de comedores sociales, grupos de autoayuda y también a participantes en asambleas de la PAH. Son estas personas ‘vulnerables’, cuestión que condiciona aspectos claves del diseño metodológico. Se argumenta que la perpetuación en la marginalidad es un elemento importante a la hora de entender las actitudes. La perpetuación en la exclusión y la pobreza puede desembocar en una desconexión permanente con la política. No obstante, si se dan las condiciones necesarias, la política, y en particular el activismo, puede concebirse como un medio para mejorar la realidad cotidiana.
This article draws on ethnographic research on the political attitudes of people who have been directly affected by the economic crisis of 2008. Analyses that use survey data do not always pay the necessary attention to expressions of advanced marginalization. This article uses observation and interviewing with users of soup kitchens, support groups and housing related forms of activism (the PAH, for instance). They are addressed as vulnerable communities, a relevant issue when it comes to research design. The path that leads towards marginalization is relevant for political attitudes. The more social exclusion and poverty become chronic, the higher the chances of a permanent disconnection with politics. However, under the right conditions, politics, and activism, can become a pathway for a better reality.
SPAWAVE, An Empirical Method to Predict Wave Added Resistance in all Wave Directions
Authors: Grin Rob
Published: September 2022

In the last 5 years, major improvements have been made in the prediction of wave added resistance with high fidelity numerical methods like Rankine source panel methods and CFD. These methods provide accurate ship and loading condition specific predictions of added resistance in all wave conditions. However there is still a need for low fidelity prediction methods in for instance concept design, speed trails, regulatory frameworks and operational support. In these applications, hull lines are often not (or not easily) available, but main dimensions and hydrostatics are. For this reason a number of empirical prediction methods has been developed, most of them (like STAWAVE) are suitable for head waves only, but more recently also a number of methods became available for all wave directions. One of the more recent methods is SPAWAVE, which has been developed with the service performance analysis performance joint industry project (SPA JIP) in 2008.

This paper presents the SPAWAVE method including its coefficients. Furthermore it shows the results of the comparison between the most commonly used prediction methods (for instance STAWAVE and SNNM) and model tests for almost 80 different ships, comprising over 2800 tests in regular waves and over 1000 tests irregular seas.
Ship Design Optimization Framework Considering Future Uncertain Carbon Emission Regulations
Authors: Wei Qikun , Liu Yan
Published: September 2022

In order to combat global climate change and reduce harmful emissions, various countries and International Maritime Organization (IMO) have issued and updated regulations that limit ship gas emissions. From a long-term perspective, more and more relevant regulations will be introduced for the development of green shipping. However, the uncertainty of policies poses a large challenge to ship design, especially early ship design. Without considering the uncertainty of policy, the ship design may have been excessive eco-friendly or under-eco-friendly in the long term, affecting the vessels in delivering value to key stakeholders throughout the lifecycle of the system.

This paper proposes a model to optimize the main design indicators of the ship to deal with the uncertainty associated with future environmental regulations and to ensure that the economic performance of the ship can still maintain market competitiveness. The optimization model is mainly composed of three parts, namely, the uncertainty prediction model of environmental regulation trends, the evaluation of the economic performance of the ship design and the modeling of the ship. Among them, the regulation uncertainty prediction model proposes a new ship emission indicator based on the current regulations, considering that the current regulations are facing unforeseen changes. The regulations trend simulation is loosely based on a Jump-diffusion process and then add bounds to create an uncertain environmental regulations scenario by using extrapolation. The proposed method is used to simulate the future regulation trends in a range to provide advice for designers when design freedom is still high. This framework optimizes the comprehensive economic performance of the ship that includes ship cost and total annual cost including the fuel cost of main engines, in-transit cargo inventory cost and non-fuel vessel operating cost etc.The early stage design of a container ship is used as a verification case to prove that the model can deal with the impact of regulation uncertainty effectively.
