Parent-child Engagement and Dissonance in Refugee Families Resettling in Brisbane, Australia
Authors: Colic-Peisker Val , Khawaja Nigar G. , Hebbani Aparna
Published: June 2023

This Australian-based study examined demographic and psychosocial factors associated with refugee parents’ communication with their children. Refugee parents (n = 222) from Ethiopia, Congo, and Myanmar took part in a survey. Logistic hierarchical analysis showed that parents with a higher level of acculturation were more engaged in meaningful and positive communication with their children. Parents’ acculturative stress increased their perception of intergenerational dissonance. Refugee parents’ employment status showed unexpected effects: unemployed parents reported interacting more, and more positively, with their children. Those who were confident in securing a job also interacted meaningfully with their children. Those in the workforce reported that their relationship and communication with children deteriorated.

Authors: Mereles Rodríguez Beda E. , Fiedler Jacqueline N. , Chade Miriam E.
Published: June 2023

Increasing resistance to antifungal agents and the toxicity of currently available antifungal agents has stimulated the development of new compounds with antifungal action of natural origin. Numerous scientific studies have reported on the biomedical and pharmacological properties of the de-rivatives of Ilex paraguariensis (Yerba mate). Very few scientific studies have been conducted on the phytochemical and/or pharmacological properties of its fruits, and practically none on its antimicrobial capacity. The aim of this study was to evaluate the in vitro antifungal capacity of aqueous extracts of I. paraguariensis fruits on dermatophyte fungi. Strains isolated from clinical samples of Trichophyton men-tagrophytes complex, Trichophyton rubrum, Microsporum canis, Trichophyton tonsurans and Nannizzia gypsea were used. To evaluate the antifungal capacity of the aqueous extract of yerba mate (EAFYM), a stock solution of 500 mg/ml was prepared. The quantitative microdilution method was applied in RPMI broth. A fungal inoculum of 1-3 x103 CFU/ml was used. Controls for fungal growth, sterility and commercial reference antifungals were performed. Cultures were incubated for 96 h at 35 °C. The minimum concentration of EAFYM that produced complete inhibition of fungal growth was determined by visual observation and subsequent puncture on solid medium. It is concluded that EAFYM has in vitro antifungal activity against the dermatophyte strains studied, ranging from 31.25 to 125 mg/ml.
Computational thinking: an analysis through structured programming using Scratch
Authors: Kuz Antonieta
Published: June 2023

In recent years, numerous initiatives have emerged to develop computational thinking. Computational thinking and programming are closely related they are both tools for working with algorithmic concepts. ICTs and, and specifically computer programs with a playful orientation for teaching programming are relevant since they take into consideration aspects related to the educational environment. Game-based learning is a complement that allows taking advantage of the playful component of games to train computational thinking and, therefore, various others skills. Scratch is one of the most used tools to teach programming, through visual and playful programming languages that seek to promote computational skills that involve problem solving, through active and constructive learning. In this study, theoretical foundations of structured programming are analyzed based on simple computing concepts such as handling sequences, control instructions such as loops and conditionals, and their adaptation using Scratch. For this article, a qualitative analysis is presented, supported by descriptive research. The partial findings, at this point, suggest the usefulness of applying video games to train computational thinking skills. In this way, opens the possibility of proposing extended uses of other interactive games such as Lightbot, PilasEngine, Pilas Bloques.

The problem to be discussed in this research is how the analysis of the novel Layar Terkembang by St. Alisjahbana's destiny in personality psychology approaches. Novels are works of fiction that reveal deeper aspects of humanity and are presented in a subtle way. Novel is defined as giving a firmer concentration of life, with romance which is defined as a broader design. Personality psychology is a branch of psychology that discusses and studies the nature and character of individuals as a unique personality that differs from one individual to another. The reason the researcher conducts research on the novel Layar Terkembang is because it tells the struggle of Indonesian women in terms of the id, ego, and superego. In this novel there is a psychological approach to the author's psychology and the content of the story in the novel, so that the reader feels more immersed in the novel Layar Terkembang. The purpose of this study is to describe the analysis of the novel Layar Terkembang by St. Alisjahbana's destiny in personality psychology approach. This type of research is a qualitative research using descriptive method. The data of this research are the quotations in the novel Layar Terkembang. In this study, the data source used by the researcher was the novel Layar Terkembang. From the research data findings, the researcher found 19 data. The psychology of literature on the personality of the character is about the id, there are 6 data, the ego has 7 data, and the superego has 6 data. The conclusion of the research on the literary psychology of the character's personality from all the characters in the main character and additional characters shows that the personality of the "ego" character is the most dominant.

Experimental Investigation of Helical Pile Performance for Loess Deposits Improvement
Authors: Eslami Abolfazl
Published: June 2023

Collapsible loess is classified as problematic soil found on most continents. The loess immediately collapses under stresses induced by axial compressive loading or the soil weight when exposed to moisture. In Iran, vast areas of the Golestan province are covered with Aeolian loess deposits. This paper investigates whether the simultaneous effect of inundation and pre-loading in helical pile installation is operative and effective in improving Golestan loess. The effect of installation conditions on loess collapsibility is studied via two main approaches, i.e., field investigations and physical modeling. The experimental studies include the installation of ten single and triple helix piles in the Amirkabir University of Technology Frustum Confining Vessel, i.e., FCV-AUT. Also, ten single and double helix piles with embedment depth of 3 to 6 m and a helix diameter of 250 mm were installed in Golestan province, and full-scale pile static loading tests were performed. The results indicated that the simultaneous application of crowd loading and water pressure during the installation of helical piles results in collapsibility potential reduction due to the soil treatment. Moreover, high or low crowd loads accompanied by water pressure during pile installation bring about similar load-displacement behavior of model piles installed in FCV-AUT and full-scale helical piles. Eventually, it was illustrated that the applied improvement technique is effective on loess soils since it uses the least amount of material, machinery, and equipment while attaining the highest possible bearing capacity ratio regarding sustainability.
Online-Gespräche von Deutschlehramtsstudierenden mit einem Kulturschaffenden in Deutschland als Element einer sprachlichen und interkulturellen Ausbildung
Authors: AYNE KARACABEY Seval
Published: June 2023

Die Entwicklung sprachlich-kommunikativer Kompetenz sowie der Aufbau von interkultureller Kompetenz sind sowohl im lokalen als auch internationalen Umfeld von groβer Bedeutung. Musik ist ein kulturelles, universelles Thema, das in einem interkulturellen Kontext bei Deutschlehramtsstudierenden gemeinsame Interessen wecken kann und gleichzeitig auch eine Grundlage für interkulturelle Vergleiche darstellt. Um die Effektivität von Onlinelehre im Kontext der Sprach- und Kultursensibilisierung von Deutschlehramtsstudierenden in Zeiten von Covid-19 zu erhöhen, wurde mit einer Gruppe von türkischen Deutschlehramtsstudierenden ein Live-Online-Interview mit einem Musiker (23 Jahre alt) aus Deutschland durchgeführt. Das Ziel des Online-Interviewprojekts war es, den Aufbau von (inter-) kultureller Bildung durch authentische Kommunikation zu unterstützen, wobei das Weltwissen und die Neugier der Lernenden produktiv genutzt werden. In diesem Beitrag soll erkundet werden, inwieweit durch Live-Online-Interviews (reale Gesprӓche) die sprachlich-kommunikativen Kompetenzen sowie die interkulturellen Kompetenzen in anregender, aber auch anspruchsvoller Art und Weise gefördert werden können. Zu diesem ‘Experiment’ wurden Deutschlehramtsstudierenden befragt, die sich an dem Live-Online-Gesprӓch aktiv beteiligt hatten. In dieser Arbeit werden Einblicke in die Daten des Begegnungsprojekts gegeben. Die Befunde der qualitativen Analyse bestätigen, dass durch das Live-Online-Interviewprojekt sowohl die sprachlich-kommunikative als auch die interkulturelle Kompetenz gefördert werden. Das Gespräch mit dem Musiker erweckte Neugier und eröffnete neue Perspektiven und Kenntnisse in Bezug auf die Musiklandschaft in Deutschland und der Türkei. Es zeigte sich auch, dass Sprechhemmungen abgebaut werden, wenn die Kommunikation in einer Gruppe stattfindet, die nicht konkurriert, sondern kooperiert. Nach Meinung der befragten Deutschlehramtsstudierenden sollten solche kulturellen Aktivitäten mit deutschen Kulturschaffenden häufiger durchgeführt werden.

Published: June 2023

The present article is about the study of Darcy-Forchheimer flow of Casson nanofluid over a linear stretching surface. Effects like variable Hall current, activation energy, Diffusion thermo is also incorporated for the analysis of heat and mass transfer. The governing nonlinear partial differential equations (PDEs) with convective boundary conditions are first converted into the nonlinear ordinary differential equations (ODEs) with the help of similarity transformation, and then the resulting nonlinear ODEs are solved with the help of shooting method. The impact of different physical parameters like Activation energy, Diffusion thermo, Brownian motion, thermophoresis parameter, hall current, magnetic parameter, nonlinear radiative heat flux, Prandtl number, Lewis number, reaction rate constant, on Nusselt number, velocity, temperature and concentration profile has been discussed. It is viewed that the fluid velocity and concentration profile enhance with increasing hall parameter and Activation energy respectively.

Published: June 2023

Malaysia's manufacturing and transportation sectors are largely reliant on fossil fuels. In 2009, fossil fuels such as natural gas, coal, diesel oil, and palm oil were used to produce 94.5 percent of electricity. Concerns about energy security, crude oil price volatility, and climate change are all driving major changes in how energy, specifically electricity, is produced, distributed, and consumed. In this regard, renewable energy resources are becoming more appealing in Malaysia for long-term energy growth. There is because Malaysia has an abundance of renewable energy sources, the most important of which are biomass and solar. This article presents the potential use of pineapple wastes as one of renewable sources of energy (biomass) in Malaysia and their impacts towards environment.
Automated SpectroPhotometric Image REDuction (ASPIRED)
Authors: Lam Marco C. , Smith Robert J. , Arcavi Iair , Steele Iain A. , Veitch-Michaelis Josh , Wyrzykowski Lukasz
Published: June 2023

We provide a suite of public open-source spectral data-reduction software to rapidly obtain scientific products from all forms of long-slit-like spectroscopic observations. Automated SpectroPhotometric REDuction (ASPIRED) is a Python-based spectral data-reduction toolkit. It is designed to be a general toolkit with high flexibility for users to refine and optimize their data-reduction routines for the individual characteristics of their instruments. The default configuration is suitable for low-resolution long-slit spectrometers and provides a quick-look quality output. However, for repeatable science-ready reduced spectral data, some moderate one-time effort is necessary to modify the configuration. Fine-tuning and additional (pre)processing may be required to extend the reduction to systems with more complex setups. It is important to emphasize that although only a few parameters need updating, ensuring their correctness and suitability for generalization to the instrument can take time due to factors such as instrument stability. We compare some example spectra reduced with ASPIRED to published data processed with iraf-based and STARLINK-based pipelines, and find no loss in the quality of the final product. The Python-based, iraf-free ASPIRED can significantly ease the effort of an astronomer in constructing their own data-reduction workflow, enabling simpler solutions to data-reduction automation. This availability of near-real-time, science-ready data will allow adaptive observing strategies, particularly important in, but not limited to, time-domain astronomy.
High-energy (>40 MeV) Proton Intensity Enhancements Associated with the Passage of Interplanetary Shocks at 1 au
Authors: Lario D. , Richardson I. G. , Aran A. , Wijsen N.
Published: June 2023

We analyze periods with elevated >40 MeV proton intensities observed near Earth over a time span of 43 yr (1973–2016) that coincide with the passage of interplanetary (IP) shocks. Typically, elevated proton intensities result from large solar energetic particle (SEP) events. The IP shocks observed during these elevated-intensity periods may or may not be related to the origin of the SEP events. By choosing those cases when the shocks can be confidently associated with the solar eruption that generated the SEP event, we analyze the components of these SEP events that are localized in the vicinity of the shock (so-called “energetic storm particles”, ESPs), focusing on those events where the ESP component exceeds 40 MeV. We examine the interdependence of these high-energy ESPs with (i) the properties of the solar eruptions that generated the shocks and the SEP events, and (ii) the parameters of the shocks at their arrival at 1 au. The solar eruptions at the origin of the shocks producing >40 MeV proton ESP intensity enhancements are within ±50° longitude of central meridian and are associated with fast coronal mass ejections (plane-of-sky speeds ≳1000 km s−1). The ESP events with the largest >40 MeV proton intensity increases tend to occur when there are structures such as intervening IP coronal mass ejections and other unrelated shocks present in the solar wind through which the shock is propagating. Among the various local shock parameters considered, only the shock speed shows a certain degree of correlation with the observed ESP intensity increase.
La contribution du juge constitutionnel au développement de recours effectifs protégeant les libertés
Authors: Bonnet Julien
Published: June 2023

Solidement ancré parmi les normes de références du contrôle de constitutionnalité et régulièrement invoqué devant le Conseil constitutionnel, le droit à un recours juridictionnel effectif bénéficie d’une réelle protection. Le contrôle opéré sur son fondement est contextualisé en ce qu’il tient compte de manière interactive de différents éléments normatifs qui gravitent autour de la norme contrôlée, et intègre en vertu d’une démarche conséquentialiste les conséquences substantielles du régime procédural sur d’autres droits et libertés. En dépit d’une force normative et d’un dynamisme interprétatif indéniables, le droit au recours est l’objet d’une certaine ambivalence dès lors qu’il risque de se transformer en caution constitutionnelle permettant de réduire l’effectivité des droits et libertés. Sans compter l’abstraction traditionnelle de l’office du Conseil constitutionnel qui, bien que compensée par des éléments de concrétisation, contribue à offrir un bilan contrasté de l’effectivité du droit constitutionnel à un « recours juridictionnel effectif ».
La contribution du juge judiciaire au développement de recours effectifs protégeant les libertés
Authors: Thierry Jean-Baptiste
Published: June 2023

Même si le juge judiciaire ne semble pas être le juge naturel pour contribuer au développement de recours effectifs protégeant les libertés, l’étude de la jurisprudence démontre qu’il y prend une part active. Cette contribution est toutefois délicate à appréhender, comme le montre l’exemple de la matière pénale gouvernée par le principe de légalité criminelle. Si la contribution du juge au développement de recours s’inscrit dans le cadre de l’office qui est le sien, elle est souvent un appel au législateur pour qu’un recours soit créé. En revanche, il est moins admissible que le juge crée un recours ex nihilo au risque d’adopter des arrêts de règlement.
La responsabilité de l’ordre social régulé : sur quelques interrogations suscitées par la Théorie de la justice de Rawls
Authors: Picavet Emmanuel
Published: June 2023

La théorie de la justice proposée par Rawls, indissociablement politique et morale, constitue notamment une théorie de l’ordre organisé dans une société. À partir de la contribution de Rawls dans sa Théorie de la justice , cet article examine les rapports entre sa conception de la justice sociale et ses hypothèses concernant les fonctions qui permettent d’organiser une société dans le sens voulu. Cette problématique est abordée plus particulièrement en rapport avec la multiplication des formes d’institutionnalisation partielle des engagements et des prises de responsabilité collectives, dans un univers institutionnel désormais marqué par la figure prédominante d’un État « régulateur ».

L’ordre mondial post-guerre froide se désorganise et la puissance se diffuse vers des États moyens ou petits, les dotant de nouveaux espaces de jeu. La puissance elle-même s’analyse différemment, privilégiant les ressources plus que les capacités. Il faut repenser tant la surface stratégique des « petites puissances » que leurs moyens d’agir, dans une logique de hard power ou de soft power , ce dernier étant souvent privilégié. Ceci, en gardant à l’esprit le poids de la force, toujours dominant.

Published: June 2023

Si les spécialistes qui s’intéressent à la féminisation du leadership constatent des avancées, encore trop peu de femmes œuvrent dans les hautes sphères des organisations. Quels sont les principaux obstacles ? Le mouvement de la féminisation représente-t-il la bonne manière d’ouvrir les organisations à un modèle plus inclusif ? Au fond, quel est le leadership que l’on désire voir éclore ?

Dynamic mechanism of epileptic seizures induced by excitatory pyramidal neuronal population
Authors: Wang Zhihui , Yang Yanying , Duan Lixia
Published: June 2023

The pyramidal neuronal population (PY) in the cerebral cortex is closely related to epilepsy, while the excitability of PY is directly affected by the excitatory interneurons (EIN), the inhibitory interneurons (IN), and the thalamic relay nucleus (TC). Based on this, we use the thalamocortical neural field model to explore the dynamic mechanism of system transition by taking the synaptic connection strengths of the above three nuclei on PY as the main factor affecting seizures. The results show that the excitatory effects of EIN on PY induce transitions from 1-spike and wave discharges (SWDs) to 2-spike and wave discharges (2-SWDs), the inhibitory effects of IN on PY induce transitions from saturated state to tonic oscillation state, and the excitatory effects of TC on PY induce transitions from clonic oscillation state to saturated state. According to the single-parameter bifurcation analysis, it is found that Hopf and fold limit cycle bifurcations are the key factors leading to the state transition. In addition, the state analysis of the three pathways is carried out in pairs. The results show that the system produces more types of epileptic seizures with the combined action of EIN and TC on PY. According to the two-parameter bifurcation curve, we obtain the stable parameter areas of tonic-clonic oscillations, SWDs, 2-SWDs and saturated discharges, and clearly find the reasonable transition path between tonic-clonic seizures and absence seizures. This may provide some theoretical guidance for the transmission and evolution of seizures.

Knee osteoarthritis (OA) is a chronic degenerative joint disease affecting millions worldwide, particularly those over 60. It is a significant cause of disability and can impact an individual's quality of life. The condition occurs when the cartilage in the knee joint wears away over time, leading to bone-on-bone contact, which can result in pain, stiffness, swelling, and decreased range of motion. Deep neural networks, especially convolutional neural networks (CNN), are powerful tools in medical applications such as diagnosis and detection. This research proposes a CNN model to classify knee osteoarthritis into five categories using x-ray images. These classes are labeled: Minimal, Healthy, Moderate, Doubtful, and Severe. Furthermore, the proposed CNN model has been compared with two pre-trained transfer learning models: Xception and InceptionResNet V2. These models were evaluated based on precision, recall, F1 score, and accuracy. The results showed that although all three models performed very well, the proposed model outperformed both transfer learning models with 98% accuracy. It also achieved the highest values for other parameters such as precision, recall, and F1 score. The proposed model has several potential applications in clinical practice, such as assisting doctors in accurately classifying knee osteoarthritis severity levels by analyzing single X-ray images.
Generating a Mental Health Curve for Monitoring Depression in Real Time by Incorporating Multimodal Feature Analysis Through Social Media Interactions
Authors: Chatterjee Moumita , Kumar Piyush , Sarkar Dhrubasish
Published: June 2023

The coronavirus pandemic has led to a dramatic increase in depression cases worldwide. Several people are utilizing social media to share their depression or suicidal thoughts. Thus, the major goal of the proposed study is to examine Twitter posts by users and identify features that may indicate depressed symptoms among online users. A numerical metric for each user is proposed based on the sentiment value of their tweets, and it is demonstrated that this feature can detect depression with good accuracy by using several machine learning classifiers. The paper proposes a novel method for measuring the mental health index of an individual by combining the sentiment score with multimodal features extracted from his online activities. A real-time curve is generated using this index that can monitor a person's mental health in real time and offer real-time information about his state. The proposed model shows an accuracy of 89% using SVM, and proper feature selection is very essential for obtaining good performance.

Published: June 2023

Burns of all etiologies are among one of the leading causes of morbidity and mortality, especially those with poorer prognose. The fundamental aim of treatment is to restore the burn victim to his/her previous socioeconomic status by giving a reasonably good esthetic and functional outcome as we firmly believe that “Quality of life is as important – if not more – as life itself.” This goal can be achieved by applying the basic principles of proper evaluation, adequate resuscitation, thorough planning, and apt execution of the treatment plan and has been stressed upon since time immemorial. Through this case report, we desire to show light on the other, less talked about factors, for example, psychological support, motivation for physiotherapy, rehabilitation, and occupational therapy, which play a substantial role in reinstating the patient's socioeconomic lifestyle.

Authors: Bhuta Maunil Ajay , Gupta Deepanshu , Gogoi Sanjit , Prudhvinath K , Kar Chandrakanta , Khurana Sushant
Published: June 2023

Introduction:

Varicocele is characterised by abnormal dilation and enlargement of scrotal venous pampiniform plexus which drains blood from testicles. It is a commonly identified cause of male infertility where twisted and enlarged veins are observed in the spermatic cord. The present meta-analysis aimed at evaluating effects of varicocele embolisation (VE) on improving fertility in infertile or sub-fertile men by analysing sperm parameters.

Materials and Methods:

A systematic search of existing English literature was conducted to identify studies on changes in sperm concentration, sperm motility, sperm morphology, sperm vitality, total motile sperm count, and FSH (Follicle stimulating hormone) outcomes in patients undergoing VE procedures for the treatment of varicocele. These studies included Randomised Control Trials (RCTs), non-randomised clinical trials, comparative studies, and retrospective and prospective reviews. RevMan (Review Manager v5.4.1) software was used for statistical analysis with a random effects model to determine the standard mean difference. Quality assessment of all studies was performed using risk of bias assessment with RevMan software.

Results:

A total of 14 relevant studies describing effects of varicocele embolisation on sperm parameters were identified. Statistical analyses for sperm morphology, sperm vitality, and FSH level were insignificant. The effect of VE on sperm concentration, sperm motility, and total motile sperm count was found to be insignificant as per the pooled results of analysis.

Conclusion:

Present meta-analysis shows effectiveness of VE in improving sperm parameters considered in this study. However, high-quality RCTs with larger sample size are necessary to reach statistically significant and definitive conclusions about varicocele embolisation in improving fertility.

Published: June 2023

Objectives:

The primary objective of this study was to evaluate the efficacy of Calendula officinalis in the wound healing of burn wound in comparison with standard povidone-iodine solution.

Materials and Methods:

A prospective randomized controlled study with 3 weeks of intervention and follow-up was conducted at the Department of Burns, Plastic and Maxillofacial Surgery, Safdarjung Hospital and VMMC, New Delhi, in collaboration with Homeopathic Treatment Centre, Safdarjung Hospital, New Delhi, from January 1, 2017, to December 31, 2018. The patients between 15 and 60 years of age reporting to the burns outpatient department with burn wounds due to thermal bums having the involvement of 5%–20% of total body surface area within 24 h of injury were randomized to either the Calendula (n = 20) or Betadine (n = 20) group.

Results:

There was no significant difference between the Calendula and Betadine groups, however, by day 14, 75% of cases in theCalendula group showed 80% and above epithelization as compared to 45.0% of cases in the Betadine group. Similarly, there was no significant difference between the wound discharges between the two groups but 95% had no discharge by the 14th day in the Calendula group as compared with 65% in the Betadine group. The Calendula group had a reduced incidence of wound infection when compared with Betadine.

Conclusion:

Therefore, Calendula dressing had a positive influence in early epithelization, better control of wound discharge, and lesser infections but these need to be evaluated on adequate sample size for a definite outcome.
