Authors: Yao Xiaotong , Liang Liting , Yang Manting , Liang Zhuoji , Piao Ying , chen Jia , Liang Yanling , Fang Xiaobo
Published: January 2025

Background
Both the atherogenic index of plasma (AIP), a surrogate marker of insulin resistance, and high-sensitivity C-reactive protein (hsCRP) are predictors of stroke risk and clinical outcomes. However, most existing evidence is derived from studies involving diabetic patients, which may lead to the overestimation of the impact of the AIP and hsCRP on stroke due to the confounding effects of diabetes. This study aimed to assess the combined and interactive effects of the AIP and hsCRP on stroke events in individuals without diabetes.
Methods
A total of 8,909 participants from the China Health and Retirement Longitudinal Study (CHARLS) 2011 who were free of stroke and diabetes at baseline were included. The AIP was calculated as lg[total cholesterol (mmol/L)/high-density lipoprotein cholesterol (mmol/L)]. A subset of 5,954 participants was studied to investigate the relationship between cumulative AIP (CumAIP) and hsCRP (CumAIP) exposure and stroke incidence.The CumAIP and CumCRP were also calculated using the same algorithm.The primary outcome was physician-diagnosed stroke occurring before 2020. We employed adjusted Cox proportional hazards regression and mediation analysis to investigate the associations between the AIP, hsCRP, and stroke events.
Results
Over nine years of follow-up, 696 new stroke cases were recorded.Compared with individuals with low AIP (<0.302 [median level]) and hsCRP <1 mg/L, those with elevated levels of both the AIP and hsCRP had the highest overall risk of stroke (adjusted HR [aHR]: 1.69; 95% CI: 1.36–2.10). In a 5-year subset analysis, 497 participants suffered a stroke. Compared with individuals with low risk (CumAIP<1.29 [median level] and CumhsCRP < 4.02 mg/L [median level]), those with high risk had the highest overall risk of stroke (adjusted HR [aHR]: 1.41; 95% CI: 1.10-1.82). Moreover, hsCRP significantly mediated 5.61% of the association between the AIP and stroke, whereas the AIP mediated 1.86% of the association between hsCRP and stroke.
Conclusions
The AIP and hsCRP exhibit coexposure effects and mutual mediation in with regard to the risk of stroke. The combined assessment of the AIP and hsCRP should be promoted for residual risk stratification and primary prevention of stroke in individuals without diabetes, particularly among middle-aged populations.

Published: January 2025

Alport syndrome (AS) is the second-most frequent monogenic kidney disease and 85% of cases are caused by mutations in the genes of the α5 chains of collagen type IV (COL4A5). The early diagnosis and treatment are essential for the prognosis of AS. The clinical phenotypes of AS are very variable, which is challenging to diagnose. Genetic diagnosis is sensitive and accurate, which can recognize the affected individuals with mild phenotype for early diagnosis and predict the age at renal failure for early treatment. In addition, genetic testing will offer the available reproductive options, including prenatal diagnosis and preimplantation genetic testing (PGT). In this study, three novel COL4A5 variants (c.1834G > T, c.865G > A and c.1032 + 5G > A) were found. These variants co-segregated with the disease in multiple affected family members. In vitro splicing assay indicated that the c.1032 + 5G > A variant resulted in aberrant splicing involving exon 18 skipping. The healthy babies without these novel COL4A5 variants were born by PGT or prenatal diagnosis, respectively. Three novel variants in COL4A5 gene can provide insights into further genetic counseling or genotype–phenotype correlations.

Published: January 2025

Background Breathing exercises, particularly those involving altered inhalation/exhalation duration ratios (I/E ratios) and increased abdominal movement, have demonstrated the potential for alleviating symptoms of mental health issues. However, it remains unclear which approach is more effective. This study aims to examine how resting respiratory patterns (e.g., I/E ratios and abdominal movement) relate to mental health, potentially guiding psychologists in recommending tailored breathing exercises.Methods A total of 240 university students (120 male and 120 female) were recruited by systematic sampling. The I/E ratio and the contribution of abdominal movement to the sum of abdominal and thoracic movements AM/(AM + TM) were recorded by respiration belts, while depression, anxiety, and stress levels were assessed with the DASS-21. Data were analyzed for each gender; each gender being categorized into either a low or high level symptom category.Results Women with high stress symptoms exhibited significantly lower I/E ratios (a lower I/E ratio indicates breathing with relatively shorter inhalation and longer exhalation) compared to those with lower stress symptoms (n = 117, F = 4.198, p = 0.043, ηp² = 0.035). A negative correlation was observed between I/E ratios and depression in women (n = 117, r = -0.211, p = 0.023). For students with high anxiety symptoms, I/E ratios were negatively correlated with anxiety scores in both men (n = 61, r = -0.292, p = 0.022) and women (n = 70, r = -0.392, p < 0.001). There were no substantial correlations between abdominal movement and mental health.Conclusions In general, university students who exhibit relatively shorter inhalations and longer exhalations tend to have poorer mental health, especially among women; This respiratory pattern may represent an autonomic compensatory strategy for coping with psychological distress. More attention could be devoted to breathing exercises involving altered I/E ratios as part of mental health management programs.
Assessing Market Food Diversity of three Food Environments of Nairobi, Kenya using Spatial and Descriptive Analyses
Authors: Adundo Lucy Apiyo , Annys Sofie
Published: January 2025

The food environment (FE) is the interface where consumers interact to acquire and consume their food. Over the last two decades, the FE has changed due to lifestyle changes, globalisation, economic disparities and supermarketization. In addition, research on the food environment has focused mostly on high-income countries. Our study shows the novelty of assessing the food environment using the Market Food Diversity (MFD) in Nairobi, a rapidly urbanising city. We assessed the food environment of three income regions of Nairobi – using Market Food Diversity derived from the Minimum Dietary Diversity of Women (MDD-W) tool. In August – December 2023, we used the Global Positioning System (GPS) and a list-based questionnaire to map 3548 food vendors. Descriptive statistics show that informal vendors (86%) dominated across the three income regions compared to formal vendors (14%). The high-income region was characterised by the presence of more formal vendors (24.2%) compared to the other income regions. There were statistically significant differences in food group variations among vendors. Market Food diversity was highest in the high-income (3.11) region compared to the low- (2.71) and middle-income (2.35) regions. Our results underscore the need for policy implementation that supports local food environments that promote access to healthier and more nutritious diets, particularly in rapidly urbanizing cities of low- and middle-income countries (LMICs) such as Nairobi. Distinguishing income regions highlights the need for local policy officials to intervene to promote access to much healthier foods across the settlements.
Understanding and utilizing the inner bonds of process tensors
Authors: Cygorek Moritz , Gauger Erik
Published: January 2025

Process tensor matrix product operators (PT-MPOs) enable numerically exact simulations for an unprecedentedly broad range of open quantum systems. By representing environment influences in MPO form, they can be efficiently compressed using established algorithms. The dimensions of inner bonds of the compressed PT-MPO may be viewed as an indicator of the complexity of the environment. Here, we show that the inner bonds themselves, not only their dimensions, have a concrete physical meaning: They represent the subspace of the full environment Liouville space which hosts environment excitations that may influence the subsequent open quantum systems dynamics the most. This connection can be expressed in terms of lossy linear transformations, whose pseudoinverses facilitate the extraction of environment observables. We demonstrate this by extracting the environment spin of a central spin problem, the current through a quantum system coupled to two leads, the number of photons emitted from quantum emitters into a structured environment, and the distribution of the total absorbed energy in a driven non-Markovian quantum system into system, environment, and interaction energy terms. Numerical tests further indicate that different PT-MPO algorithms compress environments to similar subspaces. Thus, the physical interpretation of inner bonds of PT-MPOs both provides a conceptional understanding and it enables new practical applications.
Performative activism or performativity of activism: From conceptualization to research
Authors:   St. Petersburg State University, Tkachenko Kirill V.
Published: January 2025

If modern theories of performativity seek to provide an explanation of how reality is fulfilled (produced), taking into account meanings, people and various material objects in their consideration, then social activism is a phenomenon that well demonstrates the main intention of performativity — joint execution and transformation of reality (through solving social problems). To find out how social activism is studied with the help of performativity theories, we directed research attention inside this subject field, where a paradox was discovered in the semantic relationship between the definitions of performative activism and performativity of activism. If the term “performative activism” acquires its semantic content emphasizing the opposition between words (posts) and real actions to solve social problems, then the theories of performativity themselves were developed precisely on the basis of removing the opposition between words and actions. The discovered paradox of using the term “performativity” allowed us to formulate the problem of research as uncertainty about the features of conceptualization of the performative dimension of social activism. Therefore, the aim of the work was to review the literature aimed at clarifying how modern researchers conceptualize social activism, based on the resources of scientific theories of performativity, and not on the media understanding of this term. Based on the analysis of the selected articles (N = 13), the following topics were highlighted: the performativity of activism and the fight against oppression; activism and the methodology of performativity by Judith Butler; the performativity of digital activism; theorizing about the performativity of activism. It is concluded that these topics are characterized by the use of left-progressive theories, low attention to how exactly activists produce a new reality by solving social problems (researchers often attribute a priori positions to them), as well as weak use of empirical data, which opens up prospects for more rigorous sociological studies of the performativity of social activism.
Why Russians don’t trust the USA: Analysis of World Values Survey data
Authors:   Ural Federal University named after the First President of Russia B.N. Yeltsin, Mukhametov Ruslan S.
Published: January 2025

Public opinion polls in Russia show that the majority of Russians have a negative attitude towards the United States. Under these conditions, it seems interesting to understand the origins of anti-American sentiments in Russian society. The purpose of this article is to identify the factors that explain the nature of anti-Americanism in the mass consciousness of the country’s citizens. The source of the information was the data of the seventh wave of the World Values Survey. The author has tried to empirically test a number of working hypotheses formulated on the basis of the main provisions of the theory of post-materialistic values of R. Inglehart, S. Huntington’s clash of civilizations concepts, as well as the Scapegoat theory. The data obtained indicate that the more citizens consider Russia to belong to European civilization, the higher their trust in the United States. For those who adhere to the point of view that Russia is an independent/Eurasian or some other civilization, a negative attitude towards the United States is characteristic. It is shown that anti-Americanism in Russia does not depend on the values that citizens adhere to (traditional or post-materialistic). It was found that the thesis that citizens who are dissatisfied with their financial situation are more likely to transfer this discontent to USA has not been confirmed. An important result of the study is that the level of anti-Americanism in women is higher than in men. The article emphasizes that people with a higher level of education are less critical of Washington. The results of this study demonstrate that the Russian public is very sensitive to pro-government news content.
“Young at heart”: Social practices of “silver” volunteers (case of the Altai Territory)
Authors:   Altai State University, Popov Evgeniy A.
Published: January 2025

The article is related to the problem of active old age of Russians. The activities of the “silver” volunteers in the Altai Territory have become the object of research, and the subject is their social practices aimed at self-realization, cohesion around a common cause, intergenerational connection, integration into society, etc. The main focus when considering this issue is on the conceptualization of active old age. This approach makes it possible to identify the value attitudes of a particular reference group on a theoretical level, to show its social activity and involvement in intergenerational relations. At the same time, active old age is considered as a concept that focuses on a set of specific social practices, participation in which affects the social well-being of the older generation and affects their life strategies. The article is based on the results of interviews with “silver” volunteers (N = 22). The aim is to identify the attitude of older people to social activity in general, volunteering as a social phenomenon and specific social practices related to active old age and volunteering. The trend “young at heart” used by the “silver” volunteers themselves is analyzed from the point of view of its semantic conceptualization and involvement in the active life strategies of the subjects. As it is established, a common cause becomes one of the important factors of volunteer activity, their cohesion, achieving results in helping and supporting other people, as well as in meaningful life realization. The most significant social practices in the activities of the “silver” volunteers were identified — creative, inclusive, patriotic. These practices are aimed not only at developing the communication ties of the “silver” volunteers, but also at increasing their activity and involvement in social life.
Trust, Trustworthiness and the Moral Dimension in human-AI Interactions
Authors: Donati Donatella
Published: January 2025

The growing use of Autonomous Agents (AAs) in both private and public sectors raises crucial questions about trust. As AI systems take on increasingly complex tasks and decisions, their interactions with human agents (HAs) raise questions about the relevance and applicability of traditional philosophical concepts of trust and trustworthiness (sections 1 and 2). In this paper, I will explore the nuances of trust in AAs, arguing against both the complete dismissal of trust as misplaced (section 4) and the application of “genuine” trust frameworks (section 5). My aim is to lay the groundwork for the understanding that the moral complexity of interactions with AAs goes beyond the mere reliance we place on inanimate objects (section 6).
Manyone: (A) History?

Published: January 2025

Ten years ago, the artists Juan Dominguez, Mette Edvardsen, Alma Söderberg and Sarah Vanhee started dreaming about a way of organizing their artistic practices differently. In 2015 their artist-run structure Manyone started as a subsidized organization. Now it no longer exists. Why does an artistic organization come to an end? What lessons can we draw from its existence? What traces does it leave?
The influence of social networks on the construction of historical memory
Authors: Dzihorа Kyrylo
Published: January 2025

The article is devoted to the study of the modern social networks’ impact on the content and form of historical memory as a social and personal phenomenon. The author proposes to consider the historical memory presented in social networks as a certain graph of a fractal nature, that is, one that can contain other graphs as elements. This consideration permits to single out two fields of historical memory’s consideration in social networks: the influence of the historical narrative on the elements of the graph, as well as its influence on the connections between these elements. The author considered the effects of post-truth, timelessness, polarization, forgetting or distortion of the memories’ space, which arise due to the influence of social networks’ memories. It is shown that these effects can arise not only as a result of the social network actors’ deliberate actions, but also as a result of the networks’ principles themselves. They can also influence both the content of the conceptual memory framework and the very elements present in the community's memory.

Published: January 2025

The incidence of antifungal-resistant pathogenic fungi has steadily increased around the globe and calls for an aggressive response. The study aimed to produce and evaluate virgin coconut oil's phytochemical properties and antifungal potentials (VCO). The production of VCO was achieved by hot extraction and natural fermentation methods. Gas Chromatography-Mass Spectrometry (GC-MS) was used to evaluate the active phytochemicals in the VCO. The antifungal activities of VCO against Aspergillus flavus, Aspergillus niger, Candida albicans, Candida krusei, Penicillium chrysogenum, and Trichphoyton rubrum of clinical origin were determined by the agar-well diffusion method. The percentage yield of VCO obtained from Cocos nucifera nuts by hot extraction and natural fermentation methods was 12.80% (w/w) and 11.72% (w/w), respectively. The yield from the hot extraction method was higher but not significantly different from the latter (p = 0.07). The phytochemical analysis revealed twelve chemical compounds. The VCO exerted antifungal effects at various concentrations, except at 3.125 mg/mL. Aspergillus flavus, Aspergillus niger, Candida albicans, and Penicillium chrysogenum exhibited resistance to hot-extracted VCO at 6.25 mg/mL. The test organisms were relatively more susceptible to the VCO obtained by natural fermentation than the hot extraction method, but the difference was not statistically significant (p = 0.09). This study revealed that extraction of VCO, with or without heat, possesses antifungal activities and can be used to treat infections caused by pathogenic fungal species. It is beneficial in this era of increasing antimicrobial resistance.
Participant Contributions to Person-Generated Health Data Research Using Mobile Devices: Scoping Review (Preprint)
Authors: Song Shanshan , Ashton Micaela , Yoo Rebecca Hahn , Lkhagvajav Zoljargal , Wright Robert , Mathews Debra J H , Taylor Casey Overby
Published: January 2025

BACKGROUND

Mobile devices offer an emerging opportunity for research participants to contribute person-generated health data (PGHD). There is little guidance, however, on how to best report findings from studies leveraging those data. Thus, there is a need to characterize current reporting practices so as to better understand the potential implications for producing reproducible results.

OBJECTIVE

The primary objective of this scoping review was to characterize publications’ reporting practices for research that collects PGHD using mobile devices.

METHODS

We comprehensively searched PubMed and screened the results. Qualifying publications were classified according to 6 dimensions—1 covering key bibliographic details (for all articles) and 5 covering reporting criteria considered necessary for reproducible and responsible research (ie, “participant,” “data,” “device,” “study,” and “ethics,” for original research). For each of the 5 reporting dimensions, we also assessed reporting completeness.

RESULTS

Out of 3602 publications screened, 100 were included in this review. We observed a rapid increase in all publications from 2016 to 2021, with the largest contribution from US authors, with 1 exception, review articles. Few original research publications used crowdsourcing platforms (7%, 3/45). Among the original research publications that reported device ownership, most (75%, 21/28) reported using participant-owned devices for data collection (ie, a Bring-Your-Own-Device [BYOD] strategy). A significant deficiency in reporting completeness was observed for the “data” and “ethics” dimensions (5 reporting factors were missing in over half of the research publications). Reporting completeness for data ownership and participants’ access to data after contribution worsened over time.

CONCLUSIONS

Our work depicts the reporting practices in publications about research involving PGHD from mobile devices. We found that very few papers reported crowdsourcing platforms for data collection. BYOD strategies are increasingly popular; this creates an opportunity for improved mechanisms to transfer data from device owners to researchers on crowdsourcing platforms. Given substantial reporting deficiencies, we recommend reaching a consensus on best practices for research collecting PGHD from mobile devices. Drawing from the 5 reporting dimensions in this scoping review, we share our recommendations and justifications for 9 items. These items require improved reporting to enhance data representativeness and quality and empower participants.

CLINICALTRIAL
Psychological and Behavioral Insights From Social Media Users: Natural Language Processing–Based Quantitative Study on Mental Well-Being (Preprint)
Authors: Yang Xingwei , Li Guang
Published: January 2025

BACKGROUND

Depression significantly impacts an individual’s thoughts, emotions, behaviors, and moods; this prevalent mental health condition affects millions globally. Traditional approaches to detecting and treating depression rely on questionnaires and personal interviews, which can be time consuming and potentially inefficient. As social media has permanently shifted the pattern of our daily communications, social media postings can offer new perspectives in understanding mental illness in individuals because they provide an unbiased exploration of their language use and behavioral patterns.

OBJECTIVE

This study aimed to develop and evaluate a methodological language framework that integrates psychological patterns, contextual information, and social interactions using natural language processing and machine learning techniques. The goal was to enhance intelligent decision-making for detecting depression at the user level.

METHODS

We extracted language patterns via natural language processing approaches that facilitate understanding contextual and psychological factors, such as affective patterns and personality traits linked with depression. Then, we extracted social interaction influence features. The resultant social interaction influence that users have within their online social group is derived based on users’ emotions, psychological states, and context of communication extracted from status updates and the social network structure. We empirically evaluated the effectiveness of our framework by applying machine learning models to detect depression, reporting accuracy, recall, precision, and F1-score using social media status updates from 1047 users along with their associated depression diagnosis questionnaire scores. These datasets also include user postings, network connections, and personality responses.

RESULTS

The proposed framework demonstrates accurate and effective detection of depression, improving performance compared to traditional baselines with an average improvement of 6% in accuracy and 10% in F1-score. It also shows competitive performance relative to state-of-the-art models. The inclusion of social interaction features demonstrates strong performance. By using all influence features (affective influence features, contextual influence features, and personality influence features), the model achieved an accuracy of 77% and a precision of 80%. Using affective features and affective influence features also showed strong performance, achieving 81% precision and an F1-score of 79%.

CONCLUSIONS

The developed framework offers practical applications, such as accelerating hospital diagnoses, improving prediction accuracy, facilitating timely referrals, and providing actionable insights for early interventions in mental health treatment plans.

Authors: Liao Jiaman , Huang Xueliang , Huang Hao , Shen Cuina , Li Lixia , Li Yushao , Zhan Yiqiang
Published: January 2025

BACKGROUND

With the rapid expansion of social media platforms, the demand for health information has increased substantially, leading to innovative approaches and new opportunities in health education.

OBJECTIVE

This study aims to analyze the characteristics of articles published on the “Dr Ding Xiang” WeChat official account (WOA), one of the most popular institutional accounts on the WeChat platform, to identify factors influencing readership engagement and to propose strategies for enhancing the effectiveness of health information dissemination.

METHODS

A total of 5286 articles published on the “Dr Ding Xiang” WOA from January 2021 to December 2021 were collected and analyzed. Additionally, a random sample of 324 articles was selected for detailed text analysis. Univariate analysis was conducted using the chi-square test, and multivariate analysis was performed using multivariable logistic regression.

RESULTS

In 2021, the total number of reads for “Dr Ding Xiang” articles reached 323,479,841, with an average of 61,196 reads per article. Articles exceeding 100,000 reads accounted for 33.90% of the total. Most articles were published during the time slots of 8:00-10:00 AM, 11:30 AM to 1:30 PM, and 8:30-10:30 PM. Analysis indicated that the order of publication, style of the title sentence, number of likes, number of in-views, total likes on comments, and number of replies to comments were significantly associated with an article’s number of reads. Text analysis further revealed that the article’s reasoning approaches and concluding methods also had a significant impact on readership.

CONCLUSIONS

To enhance readership and the effectiveness of health communication, health-focused WOAs should consider key factors such as optimal publication timing, engaging title design, and effective content structuring. Attention to these elements can improve user engagement and support the broader dissemination of health information.

Authors: AYDOS SEBAHAT , KÖKSAL AKYOL AYSEL
Published: January 2025

BACKGROUND

As a phenomenon that has been the subject of scientific research for many years, early marriages occur in almost all geographies. However, it is noticeable that scientific studies on children born from early marriages are quite limited.

OBJECTIVE

Aim of study was to compare height-weight-head circumference development of infants/children aged 7days-60 months born to mothers who married at an early age with WHO Multicentre Growth Reference Study (MGRS) data.

METHODS

The Study sample consisted of2209 infants/children between 7days-60 months of age born to adolescent mothers living in Ankara, the capital city of Turkey, who were followed up in Infant/Child Follow-up Data Set system of Ministry Of Health. The measurements of infants/children and mean MGRS height-weight-head circumference were compared by one-sample t-test.

RESULTS

As a result of analysis, it was found that mean height of children born to mothers who married at an early age was significantly lower than MGRS averages in both sexes, mean weight of children born to adolescent mothers was significantly lower than MGRS averages in first periods of birth (p<.o5), but difference disappeared over time and exceeded MGRS averages in following periods, and head circumference measurements of children born to adolescent mothers were significantly lower (p<.o5) than MGRS averages in both sexes.

CONCLUSIONS

Early marriages pose health risks not only for the children who are married, but also for the children born from these marriages.

Published: January 2025

BACKGROUND

Many studies have shown that better-educated adults are often associated with higher rates of internet use and digital skills who could improves the health condition by internet use.The majority of current older adults aged 60 in China lacked educational opportunities in early life who more likely excluded from the information society. Internet use has further penetrated into the older adults, together with the high prevalence of depression, it is important to have a better understanding whether education is found to play mediating role between Internet use and depression.

OBJECTIVE

To investigate Internet use and the potential associations with depression among the Chinese older adults , with a particular focus on the mediating role of education

METHODS

The data of this study were sourced from the 2021 wave of Chinese General Social Survey (CGSS), involving 3206 older adults aged 60 and above. A logistical regression model was used to explore the impact of internet use on depressive symptoms. Moreover, the add-on PROCESS macro for SPSS was employed to measure the mediating effect of education attainment on the relationship between internet use and self-report depressive feelings, controlling for covariant.

RESULTS

The results showed that internet use was significantly associated with reduced depression feelings among older adults in China. The mediating effect model showed that the total effect of the internet use on depression feelings was 0.108 and the direct effect was 0.078, and the education attainment played a mediating effect between the internet use and depression partly.

CONCLUSIONS

This study reveals that internet use has a positive effect on depressive among the older adults in China. Furthermore, this study also provides new evidence indicating that education partly mediates the relationship between internet use and depressive. Reduce digital divide could be a promising way for China to promote healthy aging in the future.
Principles of Validity in Interpretation: On Hirsch’s Method of in Defense of the Author’s Intent
Authors: Wang Xinya
Published: January 2025

Hirsch inherits the objective viewpoint of Schleiermacher and Dilthey’s partial texts, criticises psychologism, historicism, and the proponents of semantic autonomy by distinguishing between meaning and significance, defends the determinacy of meaning, and demands a return to the author’s original intention. The existence of word meaning determines the composition of text meaning. Hirsch requires the determination of the intrinsic genres in context and convention, to guess based on the inherent genres, verify interpretations with higher probability, and approach the intended meaning of the speaking subject. Hirsch proposed that verifying the validity in Interpretation is to imaginatively reconstruct the speaking subject through the evidence provided in a certain text to determine to what extent the explanation conforms to the author’s intention.
Combined effects of ultrasound power and DO on nitrogen removal in a low-intensity ultrasound (LIU)-assisted sequencing batch biofilm reactor
Authors: Chiemelie Onwuagbu Chukwubuike , Zhou Dr. Xin , Shadrack Okeke Ikechukwu , Afreh Paul
Published: January 2025

Ultrasonication is a sustainable biophysical technology used in sludge treatment. Studies show it enhances microbial activity and pollutant removal from wastewater under optimal conditions. This study examines ultrasonic irradiation's effect on nitrogen removal efficiency and extracellular polymeric substances (EPS) formation in Sequencing Batch Biofilm Reactors (SBBRs). Four reactors with different ultrasonic powers (0 W, 180 W, 270 W, and 360 W) and dissolved oxygen (DO) concentrations were tested to explore the interaction between ultrasonic treatment and nitrogen transformation. Results show that moderate ultrasonic power (180 W and 270 W) significantly improves ammonia nitrogen and total nitrogen (TN) removal rates, reaching up to 99.4% and 91.7% at a 2 mg/L DO concentration. Higher power (360 W) increased EPS production, especially tightly bound EPS, enhancing biofilm stability and microbial protection, but did not improve nitrogen removal. Thus, balancing ultrasonic intensity and DO is crucial for optimal performance. Microbial analysis indicates ultrasonic treatment alters microbial diversity, promoting species and aiding nitrification and denitrification. This study shows that controlled ultrasonic irradiation can enhance SBBR efficiency by adjusting microbial activity and biofilm structure, improving wastewater treatment.
Black Lives Have Never Mattered!
Authors: Ndiaye Papa Amady
Published: January 2025

In the year 2023, a number of Blacks in the United States died at the hands of the police who resorted to heavy-hand arrests. This sparked a movement of protest called “Black Lives Matter”, which has been decrying this form of violence against African-Americans. Since the death of George Floyd in 2020, it has been one of the most powerful movements for the defense of Black rights. It all came to a climax on May 25, the day one which, during his arrest, George Floyd, an African-American, died of suffocation. Yet if we revisit the American history, we shall easy observe that the law enforcement agents were often used to exert violence and abuses against the Blacks, the aim being to torpedo their efforts to integrate into the mainstream society and thrive economically. The purpose of this article is to demonstrate the police or State-sponsored brutality have existed since the abolition of the slavery in the US. The denunciation of such violence is one of the main themes of the poetry of Hughes and McKay to a lesser extent.

Rufat y Jiménez Calderón (2019) sostienen que la enseñanza del español como lengua extranjera (EELE) se ve influenciada por el contexto en el que se imparten los cursos. ¿Qué decir entonces de la EELE en Canadá, país que entró en un proceso de reconciliación y paz con los pueblos originarios (Commission de vérité et réconciliation, 2012) frente a las injusticias sufridas por estas comunidades a lo largo de su historia? Debido a que todas las disciplinas tienen un papel por desempeñar en la descolonización de la enseñanza superior en Canadá, se tiene que repensar la EELE de acuerdo con este proceso con el fin de contribuir a descolonizar, por una parte, la enseñanza superior en Canadá y, por otra, los cursos de español como lengua extranjera (ELE). La presente propuesta permite desarrollar a la vez las competencias interculturales (Deardorff, 2009) e interlingüísticas de quienes aprenden (Consejo de Europa, 2001, 2020; Instituto Cervantes, 2007). Asimismo, presenta actividades didácticas y un tema poco explotado para integrarlos en la EELE con el fin de inscribir estos cursos en el proceso de descolonización de la enseñanza superior en Canadá.
Afeminamiento, amaneramiento y futbol LGBTQIAPN+
Authors: Vieira Vanrochris Helbert
Published: January 2025

El Bharbixas, primer equipo de futbol LGBTQIAPN+ de Belo Horizonte, construyó su perfil identitario alrededor del afeminamiento y de las ideas de “joto” [bicha] y “amanerado” [viado]. Tal posicionamiento llevó a este equipo a involucrarse en conflictos con otros equipos LGBTQIAPN+ brasileños. Así pues, la temática del afeminamiento se presenta como central para entender la formación del futbol LGBTQIAPN+ belo-horizontino. Para comprender esta temática, el artículo ofrece una discusión de la trayectoria de vida de niños y hombres afeminados y una reflexión acerca de los conceptos de joto y amanerado.
Los testimonios de las víctimas de violencia sexual del terrorismo de Estado argentino como agencia subversiva
Authors: Godoy Daniela
Published: January 2025

Los testimonios de víctimas de violencia sexual perpetrada por el terrorismo de estado argentino enfrentan aún obstáculos para su reconocimiento. En este artículo sostengo que desde un abordaje feminista interseccional y contextualizado es posible alojar estas denuncias y comprender esta violencia como un disciplinamiento específico, político y de género. El tratamiento del género como categoría analítica y como performatividad (Scott, Butler) permite advertir, en este caso, la subversión de mandatos normativos como militantes ayer y como testigos de crímenes de lesa humanidad hoy. Analizando la injusticia epistémica (Fricker, Medina) y el empirismo inverso (Alcoff) que afecta a las denunciantes de violencia sexual, más aún en el contexto concentracionario, se presentan las múltiples dificultades para la percepción y la atribución de credibilidad a los relatos de las víctimas. Finalmente, se plantea que estos testimonios y memorias merecen inscribirse en lo que Ciriza denomina nuestras genealogías feministas situadas.

Las macroalgas intermareales proporcionan alimento y refugio para diferentes organismos. El objetivo de este trabajo fue analizar los bivalvos asociados a macroalgas. Se realizaron muestreos en enero, mayo, julio y noviembre de 2014, se recolectaron manualmente 72 muestras de macroalgas y sus bivalvos asociados dentro de cuadros de 400 cm2 en 2 localidades de Guerrero: playas El Palmar y Las Gatas. La estructura comunitaria de los bivalvos se determinó a partir de la riqueza específica, composición, abundancia, distribución e índices comunitarios: diversidad de Shannon, equidad de Pielou y dominancia de Simpson. Cada especie de macroalga (59 spp.) se asoció con la propuesta de grupos morfofuncionales. Se analizó la cobertura de macroalgas, abundancia de bivalvos y sedimento retenido. Del total de individuos (873), se reconocieron 17 especies de bivalvos. El índice de Shannon fue de 2.15 bits/individuo. Los bivalvos se asociaron a 3 grupos morfofuncionales de macroalgas. La abundancia de bivalvos y los sedimentos retenidos disminuyeron por mes, mientras que la abundancia, cobertura y sedimentos disminuyeron al aumentar el nivel de marea. Estudios como este proporcionan información importante para el conocimiento de la diversidad costera, en este caso de una zona turística en Guerrero.

La identificación de centros de diversificación es útil para planear la conservación del germoplasma de las especies. El objetivo del estudio fue determinar las localidades que actuaron como centros de diversificación del género Pinus en México e identificar las zonas con mayor riqueza de especies de pino en la actualidad. Se construyó una base de datos de presencia (BDO) y registros fósiles (RF) para el género. A partir de ésta, se creó una malla de ~ 10 × 10 km y se determinaron centros de riqueza (CRP), centros de riqueza genética (CRG) y centros de alta diversidad (CAD) para Pinus. La coincidencia espacial de CRG, CAD y RF permitió sugerir posibles centros de diversificación de pinos (CDP). Se calculó un valor de importancia para cada CRP con base en parámetros de endemismo, rareza y riqueza de especies de pino. Se identificaron 16 CRP y 5 CDP. Los 3 CRP de mayor importancia en el país se ubican en zonas de Durango-Chihuahua (1), Coahuila-Nuevo León (2) y colindancias entre Jalisco-Zacatecas-Nayarit (3).
Una especie nueva de Triumfetta (Malvaceae: Grewioideae) de la zona centro de Guerrero, México
Authors: Rico-Arce María de Lourdes , Gual-Díaz Martha
Published: January 2025

La subfamilia Grewioideae (Malvaceae) en México está representada por 6 géneros: Apeiba, Corchorus, Heliocarpus, Luehea, Trichospermum y Triumfetta; este último es de los más diversos en la subfamilia en los trópicos de América (ca. 50 especies). En México Triumfetta comprende 35 especies, de las cuales 18 se han registrado para Guerrero. Se estudió el material colectado de la subfamilia Grewioideae, en especial, el colectado en vida por Hubert Kruse; en ellos se encontraron ejemplares con características distintas a las especies ya conocidas para el género Triumfetta en México. Se describe e ilustra Triumfetta nellydiegoae y se compara con el taxón más cercano a ella para Guerrero.
Monitoreo poblacional y estado de conservación de la ranita del Pehuenche (Alsodes pehuenche) en el valle Pehuenche, Mendoza, Argentina

La ranita del Pehuenche, Alsodes pehuenche, es endémica de los Andes centrales de Argentina y Chile, ha sido categorizada en peligro crítico por la UICN y entre sus amenazas se encuentran la ruta internacional que atraviesa los arroyos que habita, la presencia del hongo quitridio, los salmónidos exóticos invasores, el ganado y el cambio climático. El objetivo de este trabajo fue evaluar el estado actual de conservación de A. pehuenche en el valle Pehuenche para conocer tendencias poblacionales, el impacto de las amenazas y futuras acciones de manejo. Se realizaron 14 salidas de campo durante 3 temporadas (2021-2023) y se muestrearon 12 arroyos usando la técnica de encuentro visual nocturno. Se delimitaron y nombraron 7 subpoblaciones: Nacientes, del Límite, Pichintur, Rial Rojas, Nueva, Campanaria y Cajón Largo. Los resultados muestran conteos de adultos (5.82 en 200 m2 y 13.64 por hora) y de larvas (6.24 en 200 m2 y 17.76 por hora). Éstos no variaron significativamente entre temporadas, pero fueron mayores en enero y febrero. Con base en la conectividad y las amenazas, los índices del estado de conservación permiten priorizar las subpoblaciones como unidades de conservación, de las cuales la del Límite requiere esfuerzos más urgentes.
Bicentenario de la Promulgación de la Constitución de 1824 y su Comparación Frente a otras Constituciones de la Época
Authors: Hernández Gómez Luis Gustavo , Hernández Hernández Miguel Armando
Published: January 2025

El presente artículo hace referencia a la Constitución de México de 1824 en comparación con otras constituciones clave de su época, como la de Estados Unidos, Francia, Cádiz y La Gran Colombia. Si bien todas ellas obedecen el contexto histórico de cada país como revoluciones y la redefinición del poder político, del caso en particular, la Constitución mexicana estuvo influenciada por el modelo federalista de Estados Unidos, que buscaba equilibrar el poder entre el gobierno central y los estados, pero enfrentó grandes desafíos debido a las profundas divisiones sociales y regionales donde la influencia de la Iglesia y la fragmentación territorial complicaron la implementación del federalismo. Finalmente, el texto explora las diferencias entre estas constituciones en términos de derechos individuales y la relación entre la religión y el Estado, con el objetivo de resaltar cómo cada nación adaptó estos principios a su contexto específico y cómo, en el caso de México, la Constitución de 1824 representó un intento por modernizar la estructura política sin perder de vista las complejas realidades locales.
