Examining Risk and Protective Factors in the Association Between Discrimination Stress and Body Mass Index in a Sample of LatinX Adults
Authors: Bender Cassidy
Published: March 2023

In 2016, the State of Obesity Organization reported that Latinx populations (38.7%) have a higher obesity rate than non-Latinx white populations (25.6%). Discrimination stress is one factor that has been found to be associated with obesity. Studies show that greater discrimination stress is associated with increased obesity in Latinx populations; however, research has not focused on the protective and risk factors that may influence this association, such as depressive symptoms and social support. While depressive symptoms may help in explaining the association between discrimination stress and obesity, protective factors, like social support may buffer this association. The purpose of the present study was to examine depressive symptoms as a mediator and social support as a moderator of the association between discrimination stress and obesity among a sample of Latinx adults. A national sample of Latinx adults (N = 632) was recruited using Qualtrics Panel to participate in an online survey. Discrimination stress, depressive symptoms, social support, and Body Mass Index (BMI), a measure of obesity, was assessed through self-report measures. Discrimination stress was not significantly associated with BMI; however, depressive symptoms fully mediated the association between discrimination stress and BMI. Social support was not found to be a significant moderator. These results suggest that greater discrimination stress is associated with more depressive symptoms, which in turn are associated with a higher BMI among Latinx adults. These findings have implications for the development of culturally sensitive prevention programs.
Romance in “Christabel”: Fear of the Supernatural Other
Authors: Seibel Jamie , Cope Jonas
Published: March 2023

Literary romance is a difficult term to coherently define among critics. Dating back to the thirteenth century in Middle English, the number of romances written in the preceding English centuries offers an expansive opportunity for scholarly research and debate. One commonality that may be examined is the presence of a hero/heroine and a supernatural entity meant to challenge the protagonist’s inability to live up to ideals. Spanning from 1785 to 1832, British Romanticism is a movement that critics also have trouble defining. Literature written during the Romantic period includes the first and second-generation poets, who were present during and after the French Revolution respectively. The selected Romantic-era poem of study is “Christabel” by Samuel Taylor Coleridge due to its presence of a heroine in Christabel and a supernatural entity in Geraldine. When placing literary romance’s Morgan le Fay and Geraldine in juxtaposition with one another, a clearer definition of romance and Romanticism may be formed. “Christabel” invokes literary romance’s tendency to depict a supernatural other who is not inherently evil but complicates through sexual temptation the hero’s struggle with chastity. The supernatural other is someone who is outcasted and alienated from society because they are a perceived threat to normalcy. However, Sir Gawain and the Green Knight, Le Morte Darthur, and “Christabel” demonstrate how the real threat is often the hero/heroine’s inability to deny temptation. This research ultimately reveals how the hero and supernatural other become vehicles to reflect common weaknesses and flaws that make people human.
Digital Performance Activism Amongst High Schoolers - Caused by Laziness or Conformity?
Authors: Subramanian Tanay
Published: March 2023

An increasingly popular trend in today’s digital age has been the use of social media to garner greater support for social change. While activism itself is beneficial, there is a harmful derivative known as performance activism. This phenomenon occurs when an individual supports a cause to elevate their social clout, rather than being devoted to the issue. Consequently, surface-level activism arises and the problem at hand isn’t actually solved. Since existing research has explored the effects of performance activism (especially among adults), this study scrutinizes the causes of performance activism amidst teenagers. The hypothesis of this research is that high schoolers’ engagement in digital performance activism is primarily a result of lacking the time, because students are genuinely interested in civic engagement, but do not have (or make) time to act upon it. Through a mixed-methods survey design and random cluster sampling of over 300 Bay Area high school students, it is concluded that a lack of time is the primary cause of performance activism in the youth. This study contributes to the current state of research by optimizing high schoolers’ social media usage to promote efficient activism, altering how companies advertise their humanitarian efforts to the youth, and serving as a didactic way to maximize societal impact while minimizing the individual’s cost of contributing. Furthermore, this research serves as a stepping stone to future studies pertaining to youth conformity, activism, and social media.
Biomimetic and Biologically Originated Nanoparticles for Drug Delivery Applications: a brief overview and update
Authors: Yang Hoi Ching
Published: March 2023

Biomimetic and biologically originating nanoparticles are an exciting new form of drug delivery system. Examples of biologically originating nanoparticles include exosomes and other extracellular vesicles, lipoproteins, ferritins, and virus-like nanoparticles. These nanoparticles can range anywhere from 5 nm up to 1000 nm and can come in different configurations depending on the nature of the nanoparticle. Various types of drugs can be loaded into these nanoparticles including hydrophobic, hydrophilic, small molecule, and nucleic acid drugs. Specific loading techniques have been developed for each nanoparticle specie. These naturally occurring nanoparticles all undergo a similar processing process, in which they are collected, purified, and functionalized for use as drug delivery systems. The scale and relative availability within our own bodies presents a significant difficulty to using biological nanoparticles for commercial applications. Using recombinant nanoparticles, produced by bacterium and other microorganisms, is a viable alternative to human derived nanoparticles, but does require more processing to become functional. Although there are many advantages to using biologically originating nanoparticles for drug delivery, such as high target specificity, great biocompatibility, and biodegradability, they are limited by their stability, scalability, and safety as they are largely unstudied compared to current drug delivery models. Further work must be done to fully characterize and fully realize the potential of these nanoparticles.
The Effects of Cultural Assimilation on the Loss of the Tuvan and Seri Languages
Authors: Chui Jacqueline
Published: March 2023

The modern pressure to learn dominant, mainstream languages such as English, Spanish, and Mandarin increases connectivity and communication across different societies. However, when members of society succumb to cultural pressures of assimilation, they often abandon native tongues in the process (Crystal, 2002). Cultural traditions are lost when languages are lost, and indigeous cultures die. In fact, it is estimated that one language dies every two weeks, and more than a thousand languages today are listed as critically or severely endangered (Rymer, 2012). Some academics such as Wang (2007) suggest that the convergence of cultures and languages can promote integration and harmony. However, most academics view the deterioration of indigenous languages to be a negative phenomenon. In fact, Crystal (1999) asserts that diversity is a key to evolutionary success and that increased uniformity threatens the long-term survival of the human species. Diversity allows for a species to survive across different environments. This paper will review how the rise of dominant languages such as Chinese and Spanish has led to the erosion of the Tuvan and Seri languages and ultimately, the loss of identity ––the loss of culture, traditions, and customs

Probiotic yogurts are dairy products that contain beneficial live microorganisms that remain in sufficiently high numbers after being exposed to stomach acidity. Baladna, Al Maha and Rawa are local yogurts that have been commercialized in Qatar after the economic blockade was imposed on it in 2017, and their labelling does not indicate the species they include nor their CFU count per ml. This study is not only the first that attempts to characterize these yogurts as compared to imported probiotic yogurts (Yeo and Activia), but also tests a protocol aimed at enhancing some of their characteristics, including resistance to acidity, probiotic content, antibiotic property against pathogens and antibiotic resistance. The commercial yogurts available locally were incubated with local cow milk for 24 hours at 37 °C. Baladna and Rawa, showed significantly better resistance to acidity than Activia and/or Yeo probiotic yogurts and contain enough probiotic bacteria to be considered as probiotics. The yogurt BB37/24, which used Baladna as starter, showed the best results overall with the highest resistance to acidity than all yogurts including Activia, the highest abundance of Streptococcus thermophilus of all yogurts, the highest antibiotic property against Pseudomonas aeruginosa among lab synthetized yogurts, and the least resistance to streptomycin, chloramphenicol and tetracyclin. This study supports the benefits of using a longer fermentation during the production of probiotic yogurts.

Published: March 2023

This review aims to analyze the obstacles in the implementation of clinical pathways in Indonesia. Integrative review refers to the Preferred Reporting Items for Systematic Review and Meta-Analyses checklist. Literature search used PubMed, ProQuest, DOAJ, Garuda and Google Scholar with the following criteria: 1) studies using a sample of health service staff; 2) studies that present the results of obstacles in the implementation of clinical pathways; 3) published in the last 5 years (2016-2021); and 4) studies conducted in Indonesia, both in Indonesian and English. Studies are excluded if: 1) do not have the full text; 2) duplicate articles; and 3) review articles. Assessment of study quality uses the Critical Appraisal Skills Program Qualitative-Checklist, Mixed Methods Appraisal Tool-Version-2018 and the Critical Appraisal Skills Program Case Study. Six articles were identified in this review, including three qualitative studies, two mixed-methods studies and one case study. We identified a number of obstacles in the implementation of clinical pathways in several hospitals in Indonesia, but the most reported obstacles were the lack of outreach and training related to the implementation of clinical pathways in hospitals and the lack of compliance of officers in implementing clinical pathways. In the implementation of clinical pathways in several hospitals in Indonesia, many obstacles were identified that caused the implementation of clinical pathways to be not optimal. Therefore, evaluation must be carried out routinely so that it can identify various obstacles in the implementation of clinical pathways in hospitals.

Objective: To describe 6 cases of penile cancer and examine their surgical management in a tertiary level hospital.
Methods: Retrospective and descriptive study of penile cancer cases from april 2020 to may 2022 at the Hospital de Especialidades Eugenio Espejo in the city of Quito. Only cases with complete clinical history, confirmatory histopathological diagnosis and post-surgical controls were included.
Results: We describe 6 patients with penile cancer with an average age of 69 years. In the histopathological study, five patients were diagnosed with squamous cell carcinoma and one with nodular melanoma. The most frequent location was on the glans penis in four individuals. According to TNM classification, two patients were stratified as T3Nx, one as T3N1, one as T3N2, one as T4 and one as T4bN3b. In half of the cases, the treatment of choice was total penectomy plus bilateral inguinal lymphadenectomy.
Conclusions: Although penile cancer is a rare pathology, the identification of risk factors and primary lesions can help in the early diagnosis of cancer, thus avoiding metastasis to structures adnexal to the penis and consequent penectomies.

Authors: Lukman Santoso  , Marcus Gunadi Wibawa  , Muhamad Syarifudin  , Priyadi  , Titi Christiana
Published: March 2023

Peer-to-peer systems nowadays are widely used because of the scalability and high reliability. File replication and consistency maintenance are widely used techniques to achieve high system performance. These techniques are connected to each other. The connection of these techniques is consistency maintenance is needed in file replication to keep the consistency between a file and the replicas. Traditional file replication and consistency maintenance methods need a high cost. The usage of IRM (Integrated file Replication and Consistency Maintenance inP2P systems) which will achieve high efficiency at a significantly lower cost can be used to solve this problem. IRM reduces redundant file replicas, consistency maintenance overhead, and unnecessary file updates.

Published: March 2023

Power conservation is a vibrant area of research on wireless sensor networks. Several research papers have shown that using mobile sync in the sensor field, which collects data from sensor nodes via single or multi-hop communication, can save significant energy. However, sinks move slowly, which increases sensor network delays, especially in delay-sensitive applications. To address this issue, various rendezvous-based techniques are described in which a subset of sensor nodes are selected from the field as rendezvous points (RPs). The remaining nodes transfer the captured data to the next RP, where the data is buffered. The RP is then used to build a path for the mobile sink to tour and collect the buffered data. This article describes various rendezvous-based techniques and analyzes their strengths and weaknesses in terms of energy savings.
BLACK BOX APPROACH TO MONITORING CONTAINER MICROSERVICES IN FOG COMPUTING
Authors: Danang Danang  , Nuris Dwi Setiawan  , Indra Ava Adianta
Published: March 2023

In recent years IoT has developed very rapidly. IoT devices are used to monitor and control physical objects to transform the physical world into intelligent spaces with computing and communication capabilities. Compared to cloud computing, fog computing is used to support latency-sensitive applications at the edge of the network which allows client requests to be processed faster. This study aims to propose a monitoring framework for containerized black box microservices in a fog computing environment to evaluate CPU overhead, as well as to determine the operating status, service characteristics, and dependencies of each container.

This study proposes a monitoring framework to integrate computing resource usage and run-time information from service interactions using a black box approach that seeks to integrate service-level information and computing resource information into the same framework. The proposed framework is limited to observing information monitoring after the server receives a request. This study uses JMeter to simulate user actions, which send requests to the server, and this research assumes the user knows the IP address of the server. For container monitoring methods in fog computing, all are indirect monitoring methods.

The results of this study indicate that the proposed framework can provide operational data for visualization that can help system administrators evaluate the status of running containers using a black box approach. System administrators do not need to understand and modify target microservices to gather service characteristics from containerized microservices. Regarding future research, it is suggested to expand the exploration of modified system information, and that part of the container management tool code can be pre-tried so that the framework proposed in this study can provide real-time quantitative indexes for the load balancing algorithm to help optimize the load balancing algorithm.

Android is a complicated system that applications and component are usable and support for multiple work together, giving rise to highly complex interdependence relationships. Meanwhile, the Android environment is notable for being greatlty disparate and decentralized: different Operation System version is personalized and re-personalized by different parties about fast and used by whoever that can develop an application for that version. Android secure its explanation sources over an app sandbox and permissions model, where each application execution in this part can entrance only suspectible overall assets and another application component (value providers, services, activities, publication receivers) by the appropriate liscense.

This study uses Harehunter measurement to automatically detect Hare vulnerabilities in Android system applications. Harehunter and HareGuard performance evaluations were carried out in this study, both of which proved to be highly effective. The approach used here is divergent investigation, by searching all quoted, decompiled script, and obvious data for targeted attribute determination as an initial step, and running an XML parser. The outcome of this research show that the impact of Hares is very significant. The application of HareGuard in this study proved to be effective in detecting all attack applications that were made. Further evaluation of the performance impact on the minimum system host. For future research, to make Harehunter more effective, it is suggested to use a more qualified analyzer. So that this direction can be explored in more depth.

Towards improving the spatial testability of aftershock forecast models
Authors: Khawaja Muhammad Asim , Maleki Asayesh Behnam , Hainzl Sebastian , Schorlemmer Danijel
Published: March 2023

Abstract. Aftershock forecast models are usually provided on a uniform spatial grid, and the receiver operating characteristic (ROC) curve is often employed for evaluation, drawing a binary comparison of earthquake occurrences or non-occurrence for each grid cell. However, synthetic tests show flaws in using ROC for aftershock forecast ranking. We suggest a twofold improvement in the testing strategy. First, we propose to replace ROC with the Matthews correlation coefficient (MCC) and the F1 curve. We also suggest using a multi-resolution test grid adapted to the earthquake density. We conduct a synthetic experiment where we analyze aftershock distributions stemming from a Coulomb Failure (∆CFS) model, including stress activation and shadow regions. Using these aftershock distributions, we test the true ∆CFS model as well as a simple distance-based forecast (R), only predicting activation. The standard test cannot clearly distinguish between both forecasts, particularly in the case of some outliers. However, using both MCC-F1 instead of ROC curves and a simple radial multi-resolution grid improves the test capabilities significantly. Our findings suggest that to conduct meaningful tests, we should have at least 8 % and 5 % cells with observed earthquakes to differentiate between a near-perfect forecast model and an informationless forecast using ROC and MCC-F1, respectively. While we cannot change the observed data, we can adjust the spatial grid using a data-driven approach to reduce the disparity between the number of earthquakes and the total number of cells. Using the recently introduced Quadtree approach to generate multi-resolution grids, we test real aftershock forecast models for Chi-Chi and Landers aftershocks following the suggested guideline. Despite the improved tests, we find that the simple R model still outperforms the ∆CFS model in both cases, indicating that the latter should not be applied without further model adjustments.
The neXtSIM-DG dynamical core: A Framework for Higher-order Finite Element Sea Ice Modeling
Authors: Richter Thomas , Dansereau Véronique , Lessig Christian , Minakowski Piotr
Published: March 2023

Abstract. The ability of numerical sea ice models to reproduce localized deformation features associated with fracture processes is key for an accurate representation of the ice dynamics and of dynamically coupled physical processes in the Arctic and Antarctic. Equally key is the capacity of these models to minimize the numerical diffusion stemming from the advection of these features, to ensure that the associated strong gradients persist in time, without the need to unphysically re-inject energy for re-localization. To control diffusion and improve the approximation quality, we present a new numerical core for the dynamics of sea ice that is based on higher order finite element discretizations for the momentum equation and higher order discontinuous Galerkin methods for the advection. The mathematical properties of this core are discussed and a detailed description of an efficient shared memory parallel implementation is given. In addition, we present different numerical tests and apply the new framework to a benchmark problem to quantify the advantages of the higher order discretization. These tests are based on Hibler’s viscous-plastic sea ice model, but the implementation of the developed framework in the context of other physical models reproducing a strong localization of the deformation are possible.

Abstract. In response to an increasing demand for bespoke or tailored regional ocean modelling configurations, we outline fundamental principles and practices that can expedite the process to generate new configurations. The paper develops the principle of reproducibility and advocates adherence by presenting benefits to the community and user. The elements of this principle are reproducible workflows and standardised assessment, with additional effort over existing working practices being balanced against the added value generated. The paper then decomposes the complex build process, for a new regional ocean configuration, into stages and presents guidance, advice and insight for each component. This advice is compiled from across the NEMO (Nucleus for European Modelling of the Ocean) user community and sets out principles and practises that encompass regional ocean modelling with any model. With detailed and region-specific worked examples in Sects. 3 and 4, the linked companion repositories and DOIs all target NEMOv4. The aim of this review and perspective paper is to broaden the user community skill base and to accelerate development of new configurations in order to increase the time available for exploiting the configurations.
A New Simplified Parameterization of Secondary Organic Aerosol in the Community Earth System Model Version 2 (CESM2; CAM6.3)
Authors: Jo Duseong S. , Tilmes Simone , Emmons Louisa K. , Wang Siyuan , Vitt Francis
Published: March 2023

Abstract. The Community Earth System Model (CESM) community has been providing versatile modeling options, with simple to complex chemistry and aerosol schemes in a single model, in order to support the broad scientific community with various research interests. While different model configurations are available in CESM and these can be used for different fields of Earth system science, simulation results that are consistent across configurations are still desirable. Here we develop a new simple secondary organic aerosol (SOA) scheme in the Community Atmosphere Model version 6.3 (CAM6.3), the atmospheric component of the CESM. The main purpose of this simplified SOA scheme is to reduce the differences in aerosol concentrations and radiative fluxes between CAM and CAM with detailed chemistry (CAM-chem) while maintaining the computational efficiency of CAM. CAM simulation results with the current and the new SOA schemes are compared to the CAM-chem results as a reference. More consistent SOA concentrations are obtained globally when using the new SOA scheme, for both temporal and spatial variabilities. Furthermore, the overestimation of other carbonaceous aerosols (black carbon and primary organic aerosol) in CAM is greatly reduced, which results in improved global atmospheric burden and concentrations at the high latitudes of the Northern Hemisphere compared to the full chemistry version (CAM-chem). As a result, the high bias of radiative flux in the Arctic region is significantly reduced for both nudged and free-running simulations. We find that the current SOA scheme in CAM can still be used for radiative forcing calculation as the high biases exist both in pre-industrial and present conditions, but studies focusing on the instantaneous radiative effects would benefit from using the new SOA scheme. The new SOA scheme also has technical advantages including the use of identical SOA precursor emissions as CAM-chem from the online biogenic emissions, instead of pre-calculated emissions that may introduce differences. Future parameter updates on the CAM-chem SOA scheme can be easily translated to the new CAM SOA scheme as it is derived from the CAM-chem SOA scheme.
Assessing specific differential phase (KDP)-based quantitative precipitation estimation for the record- breaking rainfall over Zhengzhou city on 20 July 2021

Abstract. Although radar-based quantitative precipitation estimation (QPE) has been widely investigated from various perspectives, very few studies have been devoted to extreme-rainfall QPE. In this study, the performance of specific differential phase (KDP)-based QPE during the record-breaking Zhengzhou rainfall event that occurred on 20 July 2021 is assessed. Firstly, the OTT Parsivel disdrometer (OTT) observations are used as input for T-matrix simulation, and different assumptions are made to construct R(KDP) estimators. KDP estimates from three algorithms are then compared in order to obtain the best KDP estimates, and gauge observations are used to evaluate the R(KDP) estimates. Our results generally agree with previous known-truth tests and provide more practical insights from the perspective of QPE applications. For rainfall rates below 100 mm h−1, the R(KDP) agrees rather well with the gauge observations, and the selection of the KDP estimation method or controlling factor has a minimal impact on the QPE performance provided that the controlling factor used is not too extreme. For higher rain rates, a significant underestimation is found for the R(KDP), and a smaller window length results in a higher KDP and, thus, less underestimation of rain rates. We show that the QPE based on the “best KDP estimate” cannot reproduce the gauge measurement of 201.9 mm h−1 with commonly used assumptions for R(KDP), and the potential factors responsible for this result are discussed. We further show that the gauge with the 201.9 mm h−1 report was in the vicinity of local rainfall hot spots during the 16:00–17:00 LST period, while the 3 h rainfall accumulation center was located southwest of Zhengzhou city.

In this study, the biological breakdown of plastics at cellular and enzymatic levels was examined. Great Artesian Basin bacterial strains were characterised and classified as belonging to an entirely new genus. Cells were found to partially degrade LDPE plastic under high-temperature conditions. Then, in a novel approach, this study developed a heat pretreatment procedure which enhanced plastic biodegradation. Pretreated PBAT plastic was significantly degraded via enzymatic activity. Therefore, this research contributes towards fast, high-temperature biodegradation strategies, and helps work towards a waste-free world.
An examination of childcare educators’ feeding practices – structure and determining factors
Authors:   , Vojinov Jelena
Published: March 2023

Studies suggest that educators in early childhood education and care facilities (ECEC) influence children’s eating behaviours through the practices they employ during mealtimes. Educators regularly apply practices such as role modelling, nutrition education, satiety recognition, verbal encouragement and praise and rewards during daily interactions with the children ‘at the table’. This cross-sectional study sought to evaluate the structure and use of educators’ feeding practices in Australian centre-based childcare services and examine the relationships with key contextual factors in order to get an overview into educators’ strategies for managing and guiding children’s behaviours at mealtimes in a typical Australian childcare centre.
Neuro-musculoskeletal modelling of the thoracolumbar spine – Assessment of spinal flexion motion and the role of load-bearing structures
Authors:   , Meszaros-Beller Laura
Published: March 2023

The aim of this thesis was to describe the complex biomechanical behaviour of the human spine under flexion-extension movements using the forward-dynamics and inverse-dynamics multibody approach. The musculoskeletal simulation has shown that including inter-subject variability and passive biological structures, such as ligaments and intervertebral discs, in spine models has significant effects on the load sharing in the functional spinal unit. Furthermore, a novel experimental assessment of spinal postures was investigated in the form of a proof-of-concept study. Using medical 3D ultrasound imaging together with image registration has shown that it is feasible to use this technique for spinal reconstruction.

Family and criminogenic factors: family desocialization and family conflict
Authors: Mizdran Mihai , Băloi Florentina-Cristina
Published: March 2023

Family criminology - is a scientific direction, which in criminology in general, studies the criminogenic factors of family relationships and also the action of society on these relationships in order to prevent crime. We can say that in criminogenic research tasks, the family is understood as a group of people between whom the relations are regulated legally, also by marriage, de facto, or by family relations. The family is studied criminologically in the sense of a small social group. But not only from this point of view. Every group, including the family, brings together individuals, but there are essential differences between the relationships between them, but which still lead to the reunion between them, for different reasons: the satisfaction of living together, intergroup behavior, etc. These differences are not infrequently related to the social-intimate and social-eratic situation, with the same role in the group (father, mother-in-law, minor son). The one that presents family is also subject to research, from the position of family members who separately belong to the same family.

Authors: Stici Silvia
Published: March 2023

The wording of the notion and the importance of contracts for the provision of services in the energy field are to be made based on the provisions of the Civil Code and the special laws applicable in the energy field, including jurisprudence. The research was aimed at highlighting some aspects related to redefining the contracts for the supply of electricity and natural gas in a new wording. To this end, the notion, the legal nature and the importance of service contracts in the energy field were analyzed. Also, the concepts underlying the contracts for the provision of services in the energy field were determined. No less important in this respect are the provisions of the Civil Code of the Republic of Moldova which transposed (EU) Directive 2011/83 on consumers. In this article, special attention has also been paid to the doctrine, as the history of the evolution of the institution of contracts also has an important role to play in the provision of services in the field of energy. In the same context, the case law is of particular interest.
