Retrospective analysis of the incidence and risk factors for mortality from intertrochanteric fracture in elderly patients treated with cementless bipolar hemiarthroplasty:2-year follow-up
Authors: Li Jiachen , Yang Zhaohui
Published: April 2024

Purpose: The objective of this study was to explore the risk factors for mortality in elderly patients with intertrochanteric fractures treated with proximal femoral nail fixation(PFNA) or cementless bipolar hemiarthroplasty(CBH), as well as in patients with CBH based on subgroups of follow-up time.
Patients and Methods: A total of 231 patients who underwent PFNA or CBH at our hospital between January 2016 and October 2021 were included. We first compared the two surgical procedures, and then compared the mortality and survival groups treated with CBH based on the subgroups of follow-up time in univariate, logistic regression, and Kaplan-Meier survival estimates
Results: In our study, the survival rate and average survival time of the joint replacement group were greater than those of the intramedullary nailing group(p＜0.05), and the time from surgery to implantation in the joint replacement group was significantly shorter(p＜0.05). However, the need for blood transfusion was greater in the joint replacement group(p＜0.05), and the Harris score of the joint replacement group was also greater than that of the intramedullary nailing group(p＜0.05). The survival rates in the CBH group at the 6-month, 1-year and 2-year follow-ups were 90.4%, 84.2% and 78.9%,respectively.Univariate analysis of the CBH group showed that gender was associated with mortality at the 6-month(p＜0.05), 1-year(p＜0.05), and 2-year follow-ups(p＜0.05), and we found that ICU admission time was a risk factor for mortality at both 1-year and 2-year follow-ups(p＜0.05), which was also consistent with the logistic regression analysis.
Conclusion: Gender was an independent risk factor for mortality in all follow-up time subgroups. In addition, the amount of perioperative hemoglobin and albumin loss should be considered and measures should be taken during the perioperative period.

StHY5 promotes the synthesis of SGAs during tuber greening induced by light in potato
Authors: Wang Chao , Bai Ruqian , Zhang Saihang , Zhang Xiaomei , Luo Jilin , Chi Shaoyi , Teng Linlin , Ma Ling
Published: April 2024

Turning green due to light exposure during storage or shelfs sales poses a significant challenge on food safety issues, because of large quantities accumulation of SGAs, a set of toxic secondary metabolite, in tuber. HY5 is well known as a regulator transmit light signal in plants, but its role in tuber turning green was barely elucidated. In this study, we performed bioinformatics analysis, subcellular localization, and gene expression analysis of the StHY5 gene to clarify its function in tuber turning green after light exposure. The results showed that the StHY5 gene was expressed in both the peel and flesh of tuber but with different expression patterns. Under greening treatment, the expression of the StHY5 gene was upregulated in the flesh, showing the same pattern of change in SGAs content during greening. Further analysis indicated that StHY5 could directly up-regulate the expression of StSGT1/GAME1 and GAME4 during tuber greening induced by light. These results showed that StHY5 might play an important role in SGAs accumulation during tuber turning green and provided a foundation for further research on the function of the StHY5 gene in potato.
Effect of right ventricular dysfunction on mortality in patients undergoing maintenance hemodialysis: a retrospective cohort study
Authors: Nobayashi Hiroki , Bamba Harui , Iida Tomomichi , Aoyagi Ryuji , Maruyama Yukio , Yokoo Takashi
Published: April 2024

Background: Cardiovascular disease is a major complication in patients on maintenance hemodialysis (MHD), and heart failure is the leading cause of death among them. While the effectt of left ventricular dysfunction on patients on MHD is well known, the association between right ventricular (RV) dysfunction and their prognosis remains poorly understood.
Methods: We conducted a retrospective cohort study of 149 patients on MHD (median age, 72 years; male, 67%) between April 2022 and March 2024. All subjects underwent transthoracic two-dimensional and doppler echocardiographic examination. RV dysfunction was determined when the tricuspid annular plane systolic excursion (TAPSE) was under 16 mm. The Kaplan–Meier survival analysis was used to compare survival between patients with and without RV dysfunction. The univariate and multivariate Cox regression analyses were used to estimate the effects of RV dysfunction on all-cause mortality.
Results: Twenty out of 149 patients on MHD (13%) had RV dysfunction. Indexes of their left ventricular (LV) function (such as the LV ejection fraction and E/e' ratio) were similar to those of patients without RV dysfunction. During the follow-up period, 23 patients died (9 patients with RV dysfunction and 14 patients without RV dysfunction). Kaplan–Meier analyses showed significantly lower survival among patients with RV dysfunction (p < 0.01). The multivariate Cox regression analysis revealed that RV dysfunction was independently associated with all-cause mortality (Hazard ratios: 3.55; 95%confidence intervals, 1.39–9.05).
Conclusions: RV dysfunction is a significant risk factor for all-cause mortality among patients on MHD.
Atypical lateralization of visuospatial attention can be associated with better or worse performance on line bisection
Authors: Villar-Rodríguez Esteban , Davydova Tatiana , Marin-Marin Lidón , Avila César
Published: April 2024

The causal and statistical hypotheses diverge in determining whether the lateralization of language function in one cerebral hemisphere entails the lateralization of visuospatial function in the opposite hemisphere. Additionally, it remains unclear if the atypical organization of these functions could influence cognitive performance. This study addresses these questions by examining the hemispheric lateralization of visuospatial attention during a line bisection judgement (landmark) task in three groups of healthy non-right-handed individuals with different language production organizations: left (typical), ambilateral (atypical), and right (atypical). Consistent with the causal hypothesis, results indicate that the groups with left and right language lateralization primarily utilize the opposite hemisphere for visuospatial attention. The ambilateral group, however, displays a pattern compatible with an independent organization, supporting the statistical hypothesis. Behavioral analyses reveal that atypical lateralization of visuospatial attention (non-right) can lead to either better or worse performance during the landmark task, depending on the specific pattern. Bilateral organization is associated with reduced overall accuracy, whereas the left organization results in improved performance during the most challenging trials. These findings suggest the existence of diverse pathways to lateralization, akin to either the causal or statistical hypothesis, which can result in cognitive advantages or disadvantages.

Authors: Garcia Kyle , Suppanuntaroek Sappaya , Combates Christopher , Paster Irasema Concepción , Deal Carly , Lee Benjamin
Published: April 2024

Background
To compare the 30-day readmission rates and emergency department visit rates for patients who underwent robotic partial nephrectomy before and after March 31st, 2020.
Methods
Patients who were treated at the University of Arizona Department of Urology for renal cell carcinoma from 2017–2023 were reviewed. The patients were assigned into 2 groups, Group A underwent surgery between February 1st 2017 and March 31st 2020, and Group B underwent surgery between April 1st 2020 through May 2023. All the data were collected using REDCAP database.
Results
A total of 210 cases were reviewed (105 cases in Group A, and 105 cases in Group B). There was no statistically significant difference between Emergency department visits and re-admission rates between Group A and Group B. Group B had a significantly shorter length of stay than Group A (2.32 days and 1.34 days, p < 0.001) with no other differences between the groups.
Conclusion
There was no increase in 30-day emergency department visits and readmission rates when patients who underwent robotic partial nephrectomy were discharged on post-operative day one, when compared with those discharged on post-operative day two. Thus, our preliminary data supports that this is a safe and effective change that will allow for more open hospital beds.

“We will never catch up unless we look forward”: A qualitative analysis of barriers to healthcare access faced by racial and ethnic minority older adults in low-income neighborhoods of Chicago
Authors: Bella Gretchen , Borowski Elisa , Stathopoulos Amanda
Published: April 2024

This paper seeks to understand barriers to healthcare access faced by socially vulnerable older adults in Chicago using qualitative analysis. As the U.S. population ages, ease of healthcare access by older adults grows in importance. Yet, current literature lacks an examination of pain points and coping strategies in accessing healthcare, specifically by socially vulnerable older adults. This is especially relevant as virtual telehealth access and transportation options that shape healthcare access evolve rapidly. In this work, we conduct three listening sessions with 40 total participants to understand the lived experiences of Black and Latino older adults living in low-income areas of Chicago. Transcript data was analyzed using qualitative concept and emotion coding to identify vulnerabilities that older patients face in accessing care. This work reveals unique insight on the interfaces between transportation, healthcare, and communication systems used in healthcare access, and provides a recommendation for seeking solutions that prioritize autonomy for older adults by offering physical accessibility and customized technology.
The Enhancement of Unsupervised Cross-Modality Domain Adaptive Cardiac Segmentation: Self-Training++ and FC-CRF Optimization
Authors: Li Yongbo , Qi Xiaoyi , Wang Jinjin , Yang Fei
Published: April 2024

The training of deep convolutional neural networks requires a substantial amount of labeled data. Nevertheless, the available kinds of labels that are implemented currently to segment medical images cause high-quality image annotations that bring costly and time-consuming procedures. Moreover, distinct modalities such as CT and MRI-based cardiac images make it difficult to train a model. So, one set of image data in one modality cannot be segmented into image data in another modality efficiently. Thus, an unsupervised domain-adaptive cardiac segmentation algorithm implementing a Self-training + + algorithm is suggested to conduct a process called the cross-modality medical-image segmentation known as modality data. The algorithm produces pseudo-labels for images utilized in the target domain and introduces rare class sampling (RCS) by implementing the Self-training + + approach. Additionally, the network called the Mix Transformer semantic segmentation is enhanced by incorporating the module called the atrous spatial pyramid pooling to acquire multiscale semantic information as if it were a teacher and student network to advance the robustness of the segmentation network. Then, fully connected conditional random fields (FC-CRF) are implemented to raise the confidence level of pseudo-labeling. The proposed algorithm substantially decreases the domain bias impact on the outcomes of cardiac image segmentation when distinct modalities exist and alleviates the dependence on expert-labeled data. Then, domain-adaptive training for full cardiac medical-image segmentation is performed in two directions, namely, CT to MRI and MRI to CT cardiac images, and promising experimental outcomes are achieved even though a limited number of data is employed.
Examining the Prevalence and Risk Factors of Genital Warts among HIV-Infected and HIV-Negative Women: A Cross-Sectional Study in Cameroon
Authors: Fougang Daina Charnelle , Martin Kuete
Published: April 2024

Background
Current research primarily focuses on high-risk strains of HPV associated with cervical cancer, overlooking risk factors for low-risk HPV infections like genital warts among vulnerable women, especially concerning their HIV serology. Understanding the interplay between genital warts, HIV status, and socio-cultural factors is crucial for informing targeted prevention to alleviate the burden of genital warts in vulnerable populations.
Aims
The purpose of this study is to determine the prevalence and risk factors of genital warts among women based on their HIV serostatus.
Materials and Methods
A cross-sectional study was conducted among women seeking gynecological consultation at a public Hospital in Cameroon. Data were collected through a survey and medical records, then analyzed using SPSS version 18.0.
Results
Among 257 women attending the hospital, 60 had genital warts, with the majority being HIV-positive (63.33%). Notably, 67% of these women sought gynecology consultation for the first time for genital warts. The location and types of genital warts were associated with HIV status, with papule genital warts being more prevalent among HIV-infected women and acuminate warts among non-infected women. Additionally, associations were found between smoking, multiple sexual partners, and genital warts among HIV-positive women. The reliance on traditional medicine or homemade remedies (85%) and the high prevalence of self-medication (75%) were also observed.
Conclusions
Addressing socio-cultural barriers is essential to enhance healthcare-seeking behaviour, facilitate early detection and treatment, and alleviate the burden of genital warts and HIV. Efforts should prioritize awareness-raising, enhancing healthcare access, and integrating traditional medicine into comprehensive healthcare systems.

Windows deep transformer Q-networks: an extended variance reduction architecture for partially observable reinforcement learning
Authors: Wang Zijian , Wang Bin , Dou Hongbo , Liu Zhongyuan
Published: April 2024

Recently, one of the mainstream research directions in Reinforcement Learning involves Partial Observability(PO). One approach to addressing this task is the establishment of a sequence-tosequence model. Transformer is an excellent architecture for building a sequence-to-sequence model, and as the network of Deep Q-Networks, Transformer has achieved certain outperformed results in dealing with partial observability problems. However, Transformer relies heavily on the quality of input data. Overestimation exists in Deep Q-Networks(DQN), affecting the quality of input data to Transformer, resulting in poor training efficiency. In this work, we propose Windows Deep Transformer Q-Networks(Windows DTQN), which is an improved architecture that mitigates the overestimation issue in DQN by reducing the variance of Q-values, thereby enhancing the quality of input data and improving the training efficiency of Transformer. Our experiments demonstrate that our approach achieves better results than the current mainstream DQN algorithms in Partially Observable Markov Decision Process(POMDP).
How the brain can be trained to achieve an intermittent control strategy for stabilizing quiet stance by means of reinforcement learning?
Authors: Takazawa Tomoki , Suzuki Yasuyuki , Nakamura Akihiro , Matsuo Risa , Morasso Pietro , Nomura Taishin
Published: April 2024

The stabilization of human quiet stance is achieved by a combination of the intrinsic elastic properties of ankle muscles and an active closed-loop activation of the ankle muscles, driven by the delayed feedback of the ongoing sway angle and the corresponding angular velocity in a way of a delayed proportional (P) and derivative (D) feedback controller. It has been shown that the active component of the stabilization process is likely to operate in an intermittent manner rather than as a continuous controller: the switching policy is defined in the phase-plane, which is divided in dangerous and safe regions, separated by appropriate switching boundaries. When the state enters a dangerous region, the delayed PD control is activated, and it is switched off when it enters a safe region, leaving the system to evolve freely. In comparison with continuous feedback control, the intermittent mechanism is more robust and capable to better reproduce postural sway patterns in healthy people. However, the superior performance of the intermittent control paradigm as well as its biological plausibility, suggested by experimental evidence of the intermittent activation of the ankle muscles, leaves open the quest of a feasible learning process, by which the brain can identify the appropriate state-dependent switching policy and tune accordingly the P and D parameters. In this work, it is shown how such a goal can be achieved with a reinforcement motor learning paradigm, building upon the evidence that, in general, the basal ganglia are known to play a central role in reinforcement learning for action selection and, in particular, were found to be specifically involved in postural stabilization.

Published: April 2024

Phosphorus-31 magnetic resonance spectroscopic imaging (31P-MRSI) provides valuable non-invasive in vivo information on tissue metabolism but is burdened by poor sensitivity and prolonged scan duration. Ultra-short echo time (UTE) acquisitions minimize signal loss when probing signals with relatively short spin-spin relaxation time (T2), while also preventing first-order dephasing. Here, a three-dimensional (3D) UTE sequence with a rosette k-space trajectory is applied to 31P-MRSI at 3T. Conventional chemical shift imaging (CSI) employs highly regular Cartesian k-space sampling, susceptible to substantial artifacts when accelerated via undersampling. In contrast, this novel sequence’s “petal-like” pattern offers incoherent sampling more suitable for compressed sensing (CS). These results showcase the competitive performance of UTE rosette 31P-MRSI against conventional weighted CSI with simulation, phantom, and in vivo leg muscle comparisons.

Published: April 2024

Data-driven discovery of image-derived phenotypes (IDPs) from large-scale multimodal brain imaging data has enormous potential for neuroscientific and clinical research by linking IDPs to subjects' demographic, behavioural, clinical and cognitive measures (i.e., non-imaging derived phenotypes or nIDPs). However, current approaches are primarily based on unsupervised approaches, without use of information in nIDPs. In this paper, we proposed Supervised BigFLICA (SuperBigFLICA), a semi-supervised, multimodal, and multi-task fusion approach for IDP discovery, which simultaneously integrates information from multiple imaging modalities as well as multiple nIDPs. SuperBigFLICA is computationally efficient and largely bypasses the need for parameter tuning. Using the UK Biobank brain imaging dataset with around 40,000 subjects and 47 modalities, along with more than 17,000 nIDPs, we showed that SuperBigFLICA enhances the prediction power of nIDPs, benchmarked against IDPs derived by conventional expert-knowledge and unsupervised-learning approaches (with average nIDP prediction accuracy improvements of up to 46%). It also enables learning of generic imaging features that can predict new nIDPs. Further empirical analysis of the SuperBigFLICA algorithm demonstrates its robustness in different prediction tasks and the ability to derive biologically meaningful IDPs in predicting health outcomes and cognitive nIDPs, such as fluid intelligence and hypertension scores.

Health problems are complicated, even more so in remote areas. Collaboration has emerged as a solution to this complex problem. Some specific health worker qualities have been identified as related to the success of the collaboration, but the transformation of these qualities into collaborative behaviour remains unclear. An epistemological model of collaborative skills development was built and it was confirmed by the experiences of health workers. A research model based on interpretivism epistemology was also developed. The model was then generated using a qualitative methodology with a coding framework using deductive and inductive approaches based on the literature review and the interviews. Ten previously assigned health workers were interviewed to list their personal qualities and functions to overcome collaboration problems. The specific personal qualities of health workers determine each type of collaboration. The personality of health workers does not affect their collaborative skills with the community but is directly related to interprofessional collaboration skills.

A 360-degree evaluation model of the medical curriculum was developed by adhering to the Kirkpatrick Hierarchy. To bridge the research gap pertaining to instrument development of 360-degree evaluation, a set of tools derived from various stakeholders’ perspectives was used. This mixed-method study in the sequential exploratory design involved 797 participants for two years, April 2017 to November 2019. The three study phases involved were: the qualitative phase (18 informants), the item construction phase with exploratory factor analysis (EFA) (298 participants), and the validation phase via confirmatory factor analysis (CFA) (481 participants by random sampling). In-depth interview sessions were conducted with two stakeholder groups; lecturers and preceptors. Focus group discussion (FGD) sessions were conducted with two other groups; medical students and patients at the teaching hospital. The item construction phase was executed based on the themes that emerged from qualitative findings. Lastly, the final validation stage was performed based on the EFA results. In total, 23 themes were derived from four stakeholder groups. In the item construction phase, 13 and 10 factors were identified for lecturer and student instruments, respectively. To build the preceptor and patient tools, 10 scales were used to validate the item constructs. Thus, the 360-degree evaluation model has four levels of Kirkpatrick Hierarchy with four instrument models. The 360-degree evaluation model is valid, well-constructed, and accurately reflects the indicator variables. The evaluation model is feasible and acceptable to assess the medical curriculum.

Published: April 2024

A study was performed in 2 phases to determine the ability of 2 different modified live (MLV) bovine herpesvirus-1 (BoHV-1)vaccines to protect against conjunctivitis caused by a recent field isolate of BoHV-1. In phase I, BoHV-1 isolates were used todetermine the ability of the isolates to cause conjunctivitis and to establish a challenge model for phase II. Fifteen calves wererandomly assigned to 1 of 3 groups: 5 calves received 5 mL containing 107 tissue culture infectious dose (TCID)50/mL of BoHV-1adminisered intraocularly (topically) for 2 days, 5 calves received 5 mL of inoculum consisting of 107TCID50/mL of BoHV-1 administered intranasally for 2 days, and 5 calves served as unchallenged sentinels and received phosphatebuffered saline, 5 mL administered by the intranasal and 5 mL by the intraocular route for 2 days. All 15 calves developedpyrexia (rectal temperature greater than 103.5°F (39.7°C)), were BoHV-1 virus isolation positive from ocular swabsand 10/15 calves had increased ocular discharge and conjunctivitis. In phase II, 10 calves were intranasally vaccinated witha MLV BoHV-1, 10 calves were parenterally vaccinated with a MLV BoHV-1, and 5 calves were unvaccinated. All 25 calveswere challenged by receiving 5 mL ntraocularly of 107 TCID50/mL of BoHV-1 for 2 consecutive days. Following challenge, calves were examined daily, and blood (serum), nasal swabs, and conjunctival swab samples were obtained on study days 0, 3-7, 10, 14 and 28. Both vaccines significantly decreased post challenge ocular lesions, clinical scores, and quantity of virus isolated.

Published: April 2024

The study is an attempt to examine the day-of-the-week anomaly of fourteen Indian sectoral indices and identify profitable opportunities, considering multiple positive and negative events. The aim of this study is to analyze the day-of-the-week effect on fourteen Indian sectoral indices and find profitable opportunities while considering multiple events that have positive and negative impacts. The study takes into consideration event-based anomalies, both national and global, and provides timing for trading to generate abnormal returns from the market. At first, dummy variable regression analysis was used to understand the initial anomalies. Later, time-varying symmetrical and asymmetrical volatility models, such as Generalized Autoregressive Conditional Heteroscedasticity (1, 1) and Exponential Generalized Autoregressive Conditional Heteroscedasticity (1, 1) were applied to determine the short-term and long-term volatility persistence. These models capture the leverage effect from various events that occurred during the study. The results showed mixed outcomes during multiple positive and negative shocks. After the recession, anomalies were observed across all sectoral indices, except for commodities, energy, and information technology. During the scam period, anomalies occurred in all sectors, except for consumer durables, financial services, and information technology. However, after the new government took over, anomalies persisted in all sectors. During the pandemic, anomalies persisted in all sectors except for finance, IT, pharmaceuticals, and services. Hence, national and global events have shown varied impacts on the Indian markets. The study provides investors with implications on strategies and timing techniques for planning their investments in different sectors of the Indian economy.
The Power of Narration in Online Media to Support the Sustainability of Maos Batik
Authors: Hartanti Monica , Claudia Lukman Christine
Published: April 2024

The research showed that historical events could create a narrative on batik motifs. The chronicle of the Javanese War had always been a part of the origins of Banyumasan Batik, including Maos Batik. The narrative about the Diponegoro War code on Maos Batik was a success factor in increasing the uniqueness of the Maos Batik. Although the truth was uncertain, this narrative was published and popularized through trusted online news media. The research used narrative analysis with a qualitative descriptive approach. Narrative data were collected through reliable sources, narrative analysis from Propp, and the semiotics of the Barthes signification system to reveal the myths and ideologies contained in the Maos Batik motif. Online questionnaire data was from 108 respondents to determine the respondent interest level after knowing the Batik motif's narrative as the code for the Diponegoro War. The research reveals that the narrative of the Maos Batik motif as a code for the Diponegoro War cannot be clarified the truth of its history. However, the socialization carried out by the company owners through the popularity of the leading online news media has made this narrative considered historical truth. Strengthened by the myths contained in the Maos Batik motif, it can function to naturalize history. If this is not considered a historical fact, then the narrative can be accepted as a marketing strategy. The dissemination of the narrative in Maos Batik through trusted online news media can enhance the uniqueness of Maos Batik, which becomes a differentiation from other regions. This attracts consumers to buy and supports sustainability of Maos Batik.
Substitution of Maggot Meal (Hermetia illucens) in Feeds to The Growth Performance and Survival Rate of Goldfish (Carassius auratus)
Authors: Junus Lisya , Desrina Desrina , Herawati Vivi Endar
Published: April 2024

Protein, a macromolecular component, is relatively expensive in artificial feed because it originates from fishmeal. The study was conducted to determine and compare the effect of maggot meal in the experimental feed with commercial feed on the growth performance and survival of goldfish (Carassius auratus), and it was conducted for 30 days. This study used an experimental method, complete randomized design (CRD), including 4 treatments with 3 replicates. The treatments in this study include A as a control (commercial feed) and test feed B, C, and D, each of which has a maggot meal substitution level (g/kg test feed) of 150, 175, and 200 feed, respectively. The experimental fish in this study is goldfish with an average initial weight of 3.2 ± 1.38 grams per fish. The maintenance tank for goldfish in this study used an aquarium with a water level of 50 cm. Growth performance data taken included specific growth rate (SGR), total feed consumption (TFC), feed conversion ratio (FCR), feed utilization efficiency (FUE), and survival (SR). The results showed that substituting maggot meal in the feed had a significant effect (P<0.05) on SGR, TFC, FCR, and FUE but no effect on survival. Based on the results, the best substitution dose of maggot meal that has results close to the control treatment is 175 g/kg, which can produce SGR (0.55%/day), FUE (21.90%), FCR (3.44), TFC (26.67 grams), and SR (80%). Therefore, the 175 g/kg maggot meal can be an alternative ingredient of feed-based fishmeal for goldfish.
Effects of Microplastic Exposure on Catfish(Clarias gariepinus) Feed to Cyp19b Gene
Authors: Fadjar Mohamad , Ekawati Arning Wilujeng
Published: April 2024

Microplastics that are eaten by fish will bioaccumulate and will settle in the fish's body, especially in the gills and stomach organs. Exposure to microplastics in farmed animals can cause damage to gonadal cells and increase the level of aromatase in fish body so that the synthesis of androgens to become estrogene is higher. Cyp19b is a gene responsible for the synthesis of the aromatase enzyme which is related to the androgen hormone. The purpose of this study was to analyse the effect of giving polystyrene to catfish (C. gariepinus) feed on changes in the Cyp19b gene sequence. This research was descriptive experimental research. Results and observation data were analysed using a comparative descriptive method. The study was conducted by examining the brain of catfish (C. gariepinus) to determine changes in the Cyp19b gene sequence. The first step was to extract DNA from the gonads and fish brains, then examine the Cyp19b gene sequence. The next step was constructed a phylogenetic tree to determine if there is a change in kinship in the Cyp19b gene sequence. The results showed a trend towards changes in the Cyp19b gene sequence which can be described in a phylogenetic tree.
Reactive Pragmatic Models in Non-Professional Internet Discourse
Authors: Savel'eva Irina
Published: April 2024

The response pragmatics in political Internet discourse is one of the most interesting and understudied aspects of modern virtual communication. This research featured a model of non-professional Internet discourse in the genre of political Internet commentary and its pragmatics. The resulting models correlated with the general model, which was based on the communicative intentions of the authors of political Internet comments. The empirical material involved feedback lines from readers of the RIA Novosti news agency. Determining the textual entity by its sender’s macrointension, the authors established the genre of Internet commentary as reactive. The pragmatic options for response patterns were based on the addressee’s communicative role and the reactive macrointension implemented in non-professional Internet discourse. The paper describes two reactive models of non-professional discourse: 1) reaction to a political event; 2) reaction to a pragmatic context. The method of linguistic and pragmatic discourse analysis revealed that the reactive models contained the following types of reaction: positive, negative, and twofold. However, the Internet comments also included an interpretative component. The reactive intention of the subjects of non-professional Internet discourse was combined with their intention to introduce a fragment of personal experience.
Everyday Speech and the Principle of Saving Articulation and Manual Efforts in Real and Virtual Communication
Authors: Kobzeva Ol'ga
Published: April 2024

The article discusses the issues of saving articulatory efforts and related cognitive costs. The research relied on Western studies that link some phonetic changes to the desire of communicants to reduce articulatory efforts in the process of voicing speech segments. This desire is connected with the need to optimize the language system. Communicants try to simplify complex articulations and get rid of sounds that require significant muscular efforts of speech organs, thus changing the language system. The paper introduces examples of how some linguistic units are used in everyday speech and how these units are simplified due to the high frequency of their use. The author comes to the conclusion that frequency generates careless articulation while maintaining effective communication. The reasons for simplified articulation should be sought primarily at the deep level of the generation of primary semantic recording, i.e., in cognition, and not in the muscular work of the speech apparatus. If language is a tool that shapes a product of mental activity, the answers to the questions of language transformations should be sought directly in the cognitive sphere.

Authors: Raczyński Krzysztof , Dyer Jamie
Published: April 2024

This study introduces an improved version of the harmonic oscillator seasonal trend (HOST) model framework to accurately simulate medium- and long-term changes in extreme events, focusing on streamflow droughts in the Mobile River catchment. The updated model incorporates new mathematical formulas and waveform synthesis, resulting in improved performance. The updated framework successfully captures long-term and seasonal patterns with a Kling -Gupta efficiency exceeding 0.5 for seasonal fluctuations and over 0.9 for trends. The best-fit model explains around 98% of long-term and approximately 55% of seasonal variance. Test sets show slightly lower accuracies, with about 20% of nodes underperforming due to the absence of drought during the test phase resulting in false-positive model forecasts. The newly developed weighted occurrence classification outperforms the binary classification occurrence model. In addition, application of an automatic period multiplier for decomposition using the seasonal trend decomposition using LOESS (locally estimated scatterplot smoothing) method improves test dataset performance and reduces false-positive forecasts. The improved framework provides valuable insights for extreme flow distribution, offering potential for improved water management planning, and the combination of the HOST model with physical models can address short-term drivers of extreme events, enhancing drought occurrence forecasting and water resource management strategies.

Diante do crescimento populacional e da intensa urbanização no Brasil, o saneamento básico se torna crucialmente importante, impactando diretamente a saúde pública e alinhando-se estreitamente aos Objetivos de Desenvolvimento Sustentável (ODS) da ONU, particularmente o ODS 6. Este estudo correlacional analisa a relação entre desastres hidrológicos e casos confirmados de leptospirose no Rio de Janeiro, antes e durante a pandemia de Covid-19, utilizando dados do Atlas Digital de Desastres do Brasil e DATASUS. Os resultados indicam uma correlação forte e moderada nos períodos de 2007 a 2019 e 2007 a 2022, respectivamente, salientando a necessidade de políticas públicas eficazes em saneamento e controle de leptospirose. A pesquisa também aponta para fragilidades na coleta e tratamento dos dados, exigindo estudos adicionais para compreender plenamente a causalidade entre as variáveis estudadas. O impacto social do estudo é significativo, dado que saneamento inadequado pode levar a diversas doenças, incluindo a leptospirose, que é prevalente em condições sanitárias precárias.

As Redes Sociais Online (RSO) consitem em um espaço virtual organizado por meio de uma interface própria, a partir da agregação de perfis humanos. Este meio produz uma nova forma de relacionamento entre os indivíduos e o psicólogo está inserido nesse campo, seja como espectador, como produtor de conteúdo ou possuindo outras formas de relacionamento com esse espaço. Objetivos: Realizar um mapeamento da literatura para identificar como se dá o uso das RSO por parte do campo da psicologia, considerando todos os achados até o ano de 2023. Métodos: Realizou-se um mapeamento sistemático de literatura a partir de quatro etapas: (1) definição das questões de pesquisa; (2) execução da pesquisa; (3) extração e síntese dos dados colhidos e (4) análise dos dados. A seleção do material consistiu na extração dos resumos dos 71 estudos selecionados para a criação do corpus textual utilizando o Open Office Writer e no processamento de dados pelo software Iramuteq através da CHD (Classificação Hierárquica Descendente). Resultados: Foi possível identificar que os artigos publicados utilizando a temática das RSO no campo psi começaram a ser apresentados em revistas a partir de 2011. A natureza metodológica dos estudos expõe noções de investigações qualitativa e quantitativa. O corpus textual apresentou 4 classes que indicaram: (1) Apresentação de conteúdos referentes à construção de novos modos de vida e padrões sociais para os indivíduos; (2) Desafios em relação a forma como os indivíduos se relacionam com as RSO e os impactos em suas vidas; (3) Natureza qualitativa dos estudos como predominante; e (4) Estudos realizados no ambiente virtual, com destaque a pandemia de COVID-19. Conclusões: O uso do Mapeamento Sistemático foi satisfatório em seu resultado, permitindo responder todas as questões de pesquisa levantadas, trazendo à tona um panorama geral do uso das RSO pelo campo da psicologia

A pandemia de COVID-19 gerou mudanças profundas na sociedade, incluindo a educação. Este estudo qualitativo exploratório-descritivo investigou as percepções de docentes, discentes e técnicos administrativos da Universidade Federal Rural do Rio de Janeiro em relação à higiene durante e após a pandemia. Dos 271 participantes, 82% de docentes, 55% de discentes e 66% técnicos administrativos, respectivamente, foram infectados pela COVID-19, enfrentando sintomas comuns como febre, tosse e perda do paladar. A maioria teve a doença uma vez, com a busca por assistência médica. Enquanto mais de 60% tomaram três ou quatro doses da vacina, muitos relataram reações, enfatizando a conscientização sobre a imunização. Os participantes demonstraram conhecimento significativo sobre práticas de prevenção e higiene, com mais de 80% aderindo ao uso de máscaras faciais. Os resultados revelaram que mais de 60% mantiveram o hábito de lavar as mãos e usar álcool gel após a pandemia, embora outras práticas de higiene tenham diminuído significativamente. Este estudo destaca a necessidade de esforços persistentes para garantir a segurança e bem-estar da comunidade acadêmica e de toda a população, fortalecendo a conscientização sobre medidas preventivas e a manutenção de práticas de higiene.

Published: April 2024

Due to rising worldwide environmental issues, eco-literacy and environmental consciousness have received emphasis in recent years. This phenomenon implicitly suggests that novels can significantly elucidate intricate ecological concepts. This study aims to uncover the underlying currents that shape the discourse around eco-literacy in novels and their influence on societal perceptions of the environment. This study used Scopus and Web of Science (WoS) databases to gather and analyse datasets. ScientoPy and VOSviewer were then used to analyse the retrieved datasets. This study found that temporal trend analysis showed a gradual increase in research production, notably after 2005, showing a growing interest in the connection between eco-literacy and novel studies. The prevalence of keywords such as â€œenvironmental educationâ€, â€œeco-criticismâ€, and â€œenvironmental communicationâ€ demonstrates the significance of literature as a tool for cultivating environmental awareness, critical analysis, and effective communication in novels. This study contributes to the field by comprehensively evaluating the temporal patterns, thematic themes, and collaborative networks within eco-literacy domains and new research.

Published: April 2024

Se realizó un experimento, bajo condiciones de producción en la costa central, con los objetivos de evaluar el comportamiento de cuatro grupos fenotípicos de la familia de semilla sexual de papa ‘Chacasina’ en comparación con los cv ‘Yungay’, ‘Tomasa Tito Condemayta’ y ‘Canchan - INIAA’, y determinar la factibilidad técnico- económica del uso de tubérculos-semilla de papa ‘Chacasina’ como alternativa para esta región. Luego de la evaluación realizada se encontró que “Chacasina bulk Huancayo” logró el rendimiento más alto, encontrándose en el mismo nivel de significación con ‘Yungay’, “Chacasina piel rosada”, “Chacasina blanca” y ‘Tomasa Tito Condemayta’.  En la familia ´Chacasina´, “Chacasina bulk Huancayo”, “Chacasina piel rosada” y “Chacasina blanca”, presentan rendimientos significativamente superiores, para una siembra en costa central, que “Chacasina ojos rosados”. Los cambios en los Ingresos Netos (IN) para la familia de semilla sexual de papa ´Chacasina´ en comparación con los cv ‘Yungay’, ‘Tomasa Tito Condemayta’ y ‘Canchan - INIAA’ son positivos, en nueve de los doce casos, mientras que las diferencias entre los costos variables (CV) en todos los casos son negativas. Luego de realizar el análisis de presupuestos parciales, se concluye que la siembra de papa con tubérculos provenientes de semilla sexual de ‘Chacasina’ en condiciones de invierno en costa central es más beneficiosa que la siembra con tubérculos de variedades comerciales, convirtiéndose en una propuesta atractiva.
