Navigating and Exhibiting Ambivalence: Yin Hua Artist Organization and Sino-Indonesian Relations in the 1950s to 1960s
Authors: Isabella Brigitta
Published: May 2024

Abstract: This paper interrogates the logic of inclusion and exclusion that foregrounds the ethnocentrism and spatial boundedness of the state project’s national identity construction and proposes critical terms of discussion that challenge the limiting nation-centric framework prevalent in the dominant modern art historiography discourse. Drawing on primary archival research, it describes accounts of Lembaga Seniman Yin Hua (Yin Hua Meishu Xiehui, 印華美術協會, Yin Hua Artist Organization), an art organization established in 1955 in Jakarta and analyzes it against the backdrop of the Sino-Indonesian diplomatic relationship during the Cold War era. By engaging with the ambivalent aesthetic and politic of Chinese Indonesian artists, this paper recognizes the active and strategic agency of Chinese Indonesians as both insiders and outsiders in China and Indonesia under the uncertain circumstances of their dual nationality status. It argues that Yin Hua ambivalently navigated between the political patronage of Indonesia and China, performed dual loyalty to Indonesian and Sino-centric art history, and exhibited multiple artistic lineages that disrupted the stabilized territory of postcolonial nation-state geographical and cultural border. Weaving exhibition history, diplomatic history, and critical ethnic studies through a thread of transnational perspective, this paper provides historical narratives that unsettle the roots of racializing logic in the political articulation of nationalism and pushes toward an epistemic shift in rethinking categories of national identity, ethnicity, and citizenship.

Published: May 2024

Abstract: During Indonesia’s “New Order” (1966–98), torture became systematic. Here we present the initial findings from the Indonesia Torture Mapping (IndoTorM) dataset project, which attempts to bring together various testimonial accounts to map the spread of torture during the regime. We present initial findings on physical, sexual, and mental torture. We show how particular forms of torture were more commonly used against men, women, or children and examine the stability of these patterns across regions and over time. We argue that the patterns of torture revealed show a high degree of consistency in how severe pain and suffering was inflicted on victims during the length of the New Order. Drawing on psychological insights into how groups normalize harmful acts, such consistency indicates that the regime’s torture was not random but, rather, that it was likely learned and reinforced normative behavior. It also highlights potential areas of inconsistency or contestation.
Challenges in Commemorating the Abolition of the Slave Trade in the Académie d'Amiens Poetry Contest of 1819 and 1820
Authors: Sago Kylie
Published: May 2024

Abstract: This article considers the timing of the Académie d'Amiens poetry contest on "L'Abolition de la traite des Nègres" (1819–20), the little-known predecessor to the Académie française prix de poésie on "L'Abolition de la traite des Noirs" (1823). The Amiens concours attempted to offer a timely commemoration of the slave trade's abolition. Close readings of the competition's archival records, including twelve submitted poems and two reports, suggest reasons why a winner was never chosen. The persistence of the clandestine slave trade and pro-slavery arguments blaming abolitionism for the recent events of the Haitian Revolution challenged the possibility and value of the proposed commemoration. The Amiens contest ultimately bears witness to a shift in contemporary perceptions of the slave trade's abolition during the Bourbon Restoration: from the celebration of an event to the realization that its history was far from over.
Morale et désenchantement: Sainte-Beuve lecteur de La Rochefoucauld
Authors: Knee Philip
Published: May 2024

Abstract: Sainte-Beuve's literary criticism deserves consideration as part of the tradition of French moralistes and this article concentrates on his treatment of La Rochefoucauld. Their relationship sheds light, first on Sainte-Beuve's coming of age as he rids himself of the hold of both Catholicism and Romanticism, second on his discussion of self-love which is the central theme of the Maximes , and finally on his adoption of a method of skepticism which sidesteps the moral certainties of Christian charity and of Enlightenment progress.

Lucien Descaves on Trial: Naturalism, Sexual Politics and Patriotism in the Third Republic
Authors: Maloney Isabel
Published: May 2024

Abstract: This article examines the 1890 trial of young Naturalist writer Lucien Descaves, in which he was charged with, and later acquitted for, "injures à l'armée" and "outrages aux bonnes mœurs" following the publication of his antimilitary novel Sous-Offs (1889). I argue that literary style dominates the trial, not least because one of its key figures was an Idealist novelist with a fervent hatred of Naturalism. The article situates the trial in the context of debates about the social function of literature in the Third Republic and, crucially, anxieties about the reading habits of the peuple . I show that the trial offers a privileged lens for understanding the pressure Naturalism was under at this point in the century, insofar as it brings together, and then stages in the form of debate, the many social and cultural flashpoints touched on by the novel and how they might be represented in fiction.
Visualizing victory: the role of imagery in empowering athletes battling obsessive-compulsive disorder
Authors: Raboin Sydney
Published: May 2024

Obsessive-Compulsive Disorder (OCD) is one of the most common mental health disorders that can make activities of daily life more challenging, as well as adversely impact wellbeing. OCD is an anxiety disorder that presents as uncontrollable and unsolicited thoughts, mental images, and sensations, followed by obsession over them and an irresistible need to complete compulsive behaviors in attempt to challenge them and find relief. It causes fear of both one’s own thoughts and the world around them. OCD shows its place in the athletic realm where it can impact an athlete’s mentality, attention, behaviors, and goal orientation, which may potentially hinder the enhancement and proficiency of their skills and abilities, and create more difficulty for maintaining stability, responding to internal and external stressors, and exhibiting competency. Mental imagery techniques provide fundamental tools and coping mechanisms that can aid in the management and treatment of OCD; strengthening control of the mind and body and reducing the prevalence and severity of symptoms by enabling more attentiveness, enhancing executive functioning, promoting more effective responses to stressors, and benefiting personal growth. This paper first discusses OCD symptoms, characteristic identifiers, pathophysiology, diagnostic criteria, prognostic expectations, epidemiology in the general population and athlete population, pathogenesis in athletes, as well as the possible challenges associated with OCD and the potential to overcome them. Secondly, this paper defines mental imagery, the role of imagery as therapy, and how imagery can be used to combat OCD. This paper concludes with the review of imagery-based psychotherapy for OCD and educational sport psychology imagery-based interventions for OCD that can support the wellness of an athlete with OCD, encourage their development, and make them more equipped to achieve success.
Y luego un tiburón blanco ha abrido la boca: Spanish children’s overregularization of irregular past participles
Authors: Baker Martínez Elisabeth
Published: May 2024

The current study investigates the influence of Age, Lexical frequency, and Language background on children’s overregularization of irregular past participles (e.g., ponido ‘put’, cf. puesto). A total of 536 past participles used in compound tenses (e.g., he escrito ‘I have written’) were extracted from child speech in online corpora from both monolingual Spanish (N = 45) and Spanish-English bilingual children (N = 2) between the ages of 3;0 and 6;11. The children overregularized 7 % of their past participles and did so more often with low-frequency participles like escrito ‘written’ than with high-frequency ones like hecho ‘done/made’. Additionally, Spanish-English bilinguals overregularized more than the monolinguals, and the bilinguals’ overregularizations persisted with age while the monolingual children’s rates decreased with age. These results demonstrate that both monolingual and bilingual children overregularize irregular past participles in the structures of interest and that their overregularizations are mediated by lexical frequency. Further, these results suggest that children must be exposed to enough examples of irregular forms before they stop applying the regular pattern. While the monolingual children who were exposed to extended amounts of Spanish retreated from participle overregularization with age, bilinguals’ rates of overregularization persisted through the ages studied. These findings indicate that children from both speaker groups follow a similar acquisitional path of irregular past participles; however, language experience predicts their rates of overregularization, and the timespan required to master the irregulars.

Published: May 2024

Agomelatine (AGO) is an antidepressant with limited clinical application due to its low bioavailability caused by poor water solubility, severe hepatic degradation, and poor intracerebral distribution. Nanotechnology-based strategies constitute a powerful tool by utilizing drug solubility and targeted distribution to improve drug bioavailability in the brain tissues by nose-to-brain drug delivery. In the current study AGO was encapsulated within micelles using the commercially available Solutol HS15. As a result, AGO was efficiently loaded on the basis of least micelle size (14.17 ± 0.72 nm) and encapsulation efficiency (96.96%). In vivo and ex vivo experiments showed that micelles provided higher and more sustained brain distribution. And the results of pharmacokinetic experiments showed that micelles entered the brain region rapidly after intranasal administration and reach its peak within 0.25 h. The behavior of the nanoparticles indicated that the micelles were observed across the olfactory epithelium by examination of nasal mucosal penetration. The current study showed that HS15 micelles facilitate penetration of drugs in the olfactory epithelium and provide a system with which to target brain tissues and overcome the problem of inefficient drug delivery of insoluble drugs for central nervous system diseases.

Authors: Husaeni Yesha Ashilla , Darma Virga Putra
Published: May 2024

This study aims to analyze the impact of bipolar phases, namely manic and depressive phases, on the use of the words ‘life’ and ‘death’ in bipolar survivors’ communication. The research method used was qualitative with Likert scales to measure attitudes and perceptions towards stigma in the various bipolar phases. The results showed that bipolar phases influence survivors’ language use, where manic phases tend to produce positive connotations towards the word ‘life’ and depressive phases tend to produce negative connotations towards the word ‘life’. In addition, the social environment also influences how bipolar survivors perceive the use of these words. These findings support previous research on the impact of mood disorders on communication processes and provide additional insights into how bipolar phases influence word usage in the language of bipolar survivors.

This study presents the results of recent regional seismic exploration and deep drilling efforts in the Sayan–Yenisei syneclise and adjacent areas of the Lena–Tunguska petroleum province. These results were used to build a series of structure maps for Riphean, Vendian and Lower Cambrian reflectors; thickness maps of the Riphean and Vendian terrigenous geoseismic sequences within the syneclise, and a tectonic map of the Vendian–Paleozoic structural stage of the Sayan–Yenisei syneclise. The proposed oil and gas geological zoning of the Sayan–Yenisei potential petroleum area enabled us to identify eight potential petroleum regions and perform a quantitative assessment of the hydrocarbon potential. The original in-place resources of the Sayan–Yenisei potential petroleum area are estimated to be 3 billion 231 million tons of hydrocarbon equivalent, including 3 trillion 39 billion m3 of gas and 192.7 million tons of condensate. It is shown that over next 15–20 years, up to 1 trillion m3 gas reserves can be explored in the Sayan–Yenisei potential petroleum area. It is proposed to consider the Boguchany village as a large gas conversion and helium production center.
Approximation of Fixed Points In CAT(0) Spaces Using A New Three-Step Iteration Process For Asymptotically Quasi-Nonexpansive Mapping
Authors: Verma Anurag , Tripathi B.P.
Published: May 2024

In this paper, we introduce a new three-step iteration scheme and establish convergence results for the approximation of fixed points of asymptotically quasi-nonexpansive mapping in the framework of CAT(0) space and also give an example of a nonlinear function that is asymptotically quasi-nonexpansive but it is not quasi-nonexpansive. Finally, we display the efficiency of the proposed scheme compared to different iterative schemes by a numerical example in the literature. Our results generalize and improve many well-known results in the literature of iterations in fixed point theory.

Published: May 2024

Most microbiological growth inhibitors are toxic and chemical solvents are harmful for human health. Copper, silver, and gold metallic nanoparticles have several uses in biotechnology and medicinal research. MF-Ag-NPs(silver nanoparticles)are potent anti-inflammatory, anti-proliferative, and anti-microbial agents. The purpose of this study was to biogenically generate silver nanoparticles by extracting rutin from nutmeg, a seed from the Myristica fragrans plant. In order to create Myristica fragrans MF-Ag-NPs, silver nitrate was dissolved in the extract. The transformation of the colour from dark brown to pale brown confirmed the conversion of Ag+ to Ag°. FTIR, EDX, and SEM were used to describe them. Images from scanning electron microscopy demonstrate the presence of silver nanoparticles between 20 and 300 nm in size. The presence of oxygen and silver, as well as the metal's oxidation state, were confirmed by EDAX analysis. The nanoparticles' distinctive functional groups were discovered using FTIR spectroscopy. The antibacterial activity of Myristica fragrans seed extract was assessed. The extract from the seeds of Myrsitica fragrans exhibited the strongest antibacterial properties. These findings imply that antibacterial MF-Ag-NPs phyto-formulated with nutmeg extracts might be used to treat microbial infections in the future.

Published: May 2024

This research aims at finding the effectiveness of Remazole Red RGB dye removal using arecanut peel, an agricultural waste, as an activated carbon. The arecanut peel-activated carbon was prepared in the laboratory by carbonization followed by activation. Adsorption studies were carried out to look for the effect of different experimental scenarios, like different pH values, varying contact times, the initial concentration of dye, and changing arecanut peel carbon dosage, on the removal efficiency of Remazole Red RGB dye from the experimental solution. The equilibrium experimental results were checked for the applicability of the Langmuir and Freundlich isotherm models and the kinetic models. The batch test result was a maximum dye removal of 83% with an initial dye concentration of 5 mg/L at an adsorbent dose of 0.625 g/L at dye pH 4 in a 50-minute time span. For Remazole Red RGB dye removal, the test result is unfavorable for the Langmuir isotherm model but suits well for he Freundlich i isotherm model. The maximum adsorption capacity of arecanut peel carbon on Remazole Red RGB dye was 3.89 mg/g. It was evident that the adsorption process is favorable for the pseudo-second-order rate kinetics. It was seen that intra-particle diffusion is not the only rate-limiting step in this adsorption experimental system; also, regression results show that the linear regression model gives the best outcome. The end result of this study confirms that powder arecanut peel activated carbon was the right option for removing reactive dye from an aqueous solution.

Weightlifting exercises are coordinately complex, speed and power based movements, which simultaneously combine the maximum muscle work with different contraction types and limit the result with special functional features of the neuromuscular apparatus. According to modern views, indicators of biomechanics of the motor act and electromyographic characteristics of leading muscles during performance of the act show different aspects of the same process of contraction and can be used as criteria for an evaluation of muscle efforts and the functional state of the neuromuscular apparatus. The objective of this study is to identify special features of dynamics of muscle electric activity parameters and maximum power characteristics in different phases of weightlifting snatch. The study involved 35 male elite weightlifters with the Master of Sports qualification. The study was conducted with the BTS Motion System (made by BTS Bioengineering, Italy). A computer program was developed to analyze the technique of the snatch (the certificate RU 2020660142 from 28.08.2020). The study included registration and following analysis of biomechanical (dynamic, kinematic) and electromyographic indicators during performance of the snatch by athletes with 80 % intensity of the maximum weight directly during the training session. Features of dynamics of muscles’ electric activity parameters and maximum power characteristics, which are significantly changing in different phases of performance of the snatch, were revealed in the study. Pull phases are characterized by the increase of muscle tension, muscle work in the concentric dynamic contraction. Snatch phases are characterized by the maximum power of muscle tension and the speed of its dynamics according to both biomechanical features and electrical processes in muscles: a maximum tension and high frequency of impulsion of motor units of extensor muscles were noted. Squat phases are characterized by the decrease of muscle tension and speed of its changing, muscle work in the combined type of contraction, including eccentric and static types. High, but not maximum indicators of power and tension of muscles characterize phases of standing-up. It was revealed that the eccentric muscle contraption, according to EMG indicators, is manifested in the decrease of both amplitude and frequency characteristics. The concluded study allowed to present data characterizing biomechanics of the motor act and special physiological features of leading muscles’ work of elite weightlifters during performance of the exercise. Power and electromyographic parameters in various types of muscle work in different phases of the snatch were determined.
Elasticity and relaxation properties of oral fluid
Authors:   Ishlinsky Institute for Problems in Mechanics of the Russian Academy of Sciences, Rozhkov Aleksey
Published: May 2024

The research is aimed at crating a method for rheological testing of viscoelastic fluids, the droplets of which, when stretched, form thinning filaments, i.e. exhibit the property of spinning. The typical example of such fluid is oral fluid (or mixed saliva). Among other things, the rheological features of the oral fluid actively affect the mechanisms of transmission of infection by airborne droplets. In this work, the oral fluid was studied both from the point of view of a participant in the transmission of infection and as a model for studying the rheology of viscoelastic fluids. The method is based on video recording of the stretching of a drop of the test liquid between the legs of the tweezers and the subsequent spontaneous thinning of the formed capillary filament of the liquid. The process is controlled by the competition of forces of inertia, elasticity, capillarity. By analyzing the video recording, it is possible to trace the contribution of each factor and, within the framework of the Oldroyd/Maxwell rheological constitutive equation (rheological model), determine the numerical values of all model constants. The obtained rheological characteristics of the oral fluid make it possible to theoretically model the processes of the formation of drops of oral fluid during sneezing, coughing, talking, as well as the processes of collision of drops with protective masks, filters and other obstacles. In general, the proposed method of rheological testing is applicable for studying a wide class of viscoelastic fluids, including biological ones. Among the latter are bronchial sputum, synovial fluid, reproductive fluids, and others. The method is distinguished by the simplicity of the experiment and the use of elementary equipment.

Restoration of the locomotor function is one of the most essential problems of medicine. This problem becomes especially essential, when we deal with those children, who can’t walk from their birth. Term “abilitation” is used just in relation to such children, what means not retraining children the right stereotype of walking, but appearance of this skill and its further adequate development. Nowadays, more and more specialists, who occupy themselves with abilitation of children of the early age, realize necessity of the instrumental estimation of the locomotor function. This phenomenon is connected with the fact, that in contrast with the score system of estimation, instrumental estimation of walking is maximally concrete and exact, and complex investigation of the biomechanical and innervative structure of walking gives complete idea of the locomotor disturbances of the child. Authors of this article investigated biomechanical and innervative structure of walking of 4 healthy children at the age of 2–2.5 years. On the basis of these investigations, it has been revealed, that the following peculiarities of walking are characteristic of children at the age of 2: remarkable diminution of the mean walking velocity, increase of cadence and shortening of the step length, essential transformation of the temporal structure of walking (growth of duration of the stance and double-support phase and decrease of duration of the swing phase), flexion position of the lower extremities, displacement of all extreme values of the angular displacements to the right along the temporal axis, considerable prolongation of the maximums of activity, absence of the second maximum of activity in a number of muscles, severe disturbances in the resonance properties of the lower extremities. All these peculiarities point out to the immaturity of the process of locomotion in children at the age of 2. The received data are necessary first of all as the standard ones, because walking parameters of children with the locomotor disorders of the early age must be compared with the corresponding parameters of the healthy children of the same age.

The work is devoted to the study of the effect of local muscle fatigue on the biomechanical and viscoelastic properties of skeletal muscles. A device for non-invasive digital palpation MyotonPRO was used to carry out myotonometric measurements. The study involved 13 males and females (6 males and 7 females) aged 32.5 ± 10.6 years. Each volunteer completed two series of exercises that induce local muscle fatigue of the hand muscles. The exercises were performed with a hand grip with a resistance of 20 kg. The first series of exercises was performed until the volunteer developed a subjective fatigue, the second - until his/her refusal to continue due to excessive fatigue of the hand muscles. Testing had 3 stages: before starting strength exercises, after exertion, before subjective fatigue, and after loading with maximal exertion. Local muscle fatigue was objectively confirmed by dynamometry in accordance with the physiology standards. Myotonometry was performed on the cubital and radial flexors of the carpus, and on the abductor thumb muscle. As a result of the statistical analysis of data, it was shown that the myotonometry can be used to diagnose muscle fatigue. A change in active muscles myotometric indicators can be registered even when a subjective fatigue occurs, while local muscle fatigue does not affect the change in the tone of inactive muscles. It was also shown that the location of the measurement point of myotonometric characteristics on the muscle belly of the cubital flexor of the carpus does not affect the results with the condition that the place of application of the device is within the range of ± 2 cm from the center of the muscle belly.
Enhancing Power Grid Data Analysis with Fusion Algorithms for Efficient Association Rule Mining in Large-Scale Datasets
Authors: Sun Qiongqiong
Published: May 2024

Against the backdrop of the rapid development of information technology, the total amount of data has exploded, and efficient association rule mining methods for large-scale datasets have been studied. Conventional rule mining algorithms are subject to electrical constraints when working, and their convergence speed and data noise are currently the main problems they face. In order to accelerate the working process of the algorithm, this study introduces a data warehouse into the K-Means algorithm, and connects the time series and voltage interaction functions with the long-and-short-term memory network for efficient information analysis of power grid data, generating fusion algorithms. The study conducted experiments on the Netloss dataset and simultaneously conducted experiments on three models, including long-and-short-term memory networks, to verify the superiority of the fusion algorithm. Under the same experimental voltage, the circuit power flows of the four models were 0.37, 0.64, 0.79, and 0.82A, respectively, indicating that the algorithm effectively controlled the electrical dataset. Its measurement accuracy was the highest among the four models, at 91.7%. The experimental results show that the fusion algorithm proposed in the study has precise control ability in power grid datasets, and can effectively mine association rules on large-scale datasets.

Published: May 2024

Com a polissemia e abstração conceitual de competências interculturais, cada vez mais estudos se desenvolvem na área em busca de direcionamentos empíricos. Essa pesquisa teve como objetivo geral analisar como se desenvolvem as competências interculturais (CI) na educação superior a partir de um mapeamento sistemático (MS) da literatura. Por meio de um protocolo de pesquisa de MS, buscou-se também verificar quais as principais competências interculturais nesse contexto. Os resultados apontam para um crescimento do número de publicações científicas sobre o construto após o ano de 2015, permitindo também mapear os modelos mais adotados. Competência intercultural se desenvolve por meio de várias ações conjuntas no âmbito da ES, como capacitação de docentes, reestruturação do currículo, projetos e ações institucionalizados e o processo de internacionalização se destaca como um dos principais meios para tal. As competências interculturais se baseiam, em sua maioria, nos modelos ou instrumentos adotados em cada pesquisa.

Authors: Bandeira Victoria , Mourão Luciana , Ferreira Danielle
Published: May 2024

Durante a pandemia da Covid-19, a transição dos estudantes universitários para o Ensino Superior presencial para o Ensino Remoto Emergencial exigiu uma significativa adaptação acadêmica. O objetivo deste estudo foi explorar a relação entre a adaptação dos universitários ao Ensino Remoto e suas habilidades de autodisciplina e domínio tecnológico com sua percepção de desenvolvimento profissional durante o período pandêmico. A pesquisa envolveu 341 participantes universitários, de instituições de ensino públicas e privadas, que experimentaram o Ensino Remoto, utilizando instrumentos com evidências prévias de validade. As análises revelaram correlações positivas entre a autodisciplina, a adaptação ao ensino superior remoto e a percepção de desenvolvimento profissional, especialmente nas dimensões institucional, social e de estudo. Além disso, uma regressão múltipla linear indicou que a adaptação ao ensino superior e as experiências vivenciadas durante a pandemia atuaram como variáveis preditoras da percepção de desenvolvimento profissional dos estudantes universitários. Este estudo contribui para o campo da educação, não só fornecendo informações sobre como os estudantes universitários enfrentaram desafios durante a pandemia, mas também como as competências de domínio tecnológico e autodisciplina desempenharam papel crucial em sua adaptação e desenvolvimento profissional. As conclusões do estudo podem subsidiar políticas e práticas educacionais futuras para melhor atender às necessidades dos alunos em tempos de crise e em um ambiente de ensino em constante evolução.
Predicting the impact of water transport on carbonation-induced corrosion in variably saturated reinforced concrete

Published: May 2024

A modelling framework for predicting carbonation-induced corrosion in reinforced concrete is presented. The framework constituents include a new model for water transport in cracked concrete, a link between corrosion current density and water saturation, and a theory for characterising concrete carbonation. The theoretical framework is numerically implemented using the finite element method and model predictions are extensively benchmarked against experimental data. The results show that the model is capable of accurately predicting carbonation progress, as well as wetting and drying of cracked and uncracked concrete, revealing a very good agreement with independent experiments from a set of consistent parameters. In addition, insight is gained into the evolution of carbonation penetration and corrosion current density under periodic wetting and drying conditions. Among others, we find that cyclic wetting periods significantly speed up the carbonation progress and that the induced corrosion current density is very sensitive to concrete saturation.
Exercise in the Treatment of Repetitive, Self-Injurious, and Aggressive Behavior in Adults with Autism Spectrum Disorder: A Neurobiological Analysis
Authors: DS Im
Published: May 2024

Objective: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by markedly impaired social interaction and restricted/ repetitive patterns of behavior, interests, and activities. Maladaptive behaviors associated with ASD can include stereotyped, self-injurious, and aggressive behaviors. Current evidence-based interventions for ASD involve specialist availability, financial, time, and side effect constraints. Physical exercise has received increasing attention in the treatment of children with ASD, but research in adults is comparatively scarce. The purpose of this paper is to explore possible mechanisms by which exercise can reduce repetitive, self-injurious, and aggressive behaviors in adults with ASD. Methods: The literature on the neurobiology of exercise is reviewed and compared with the literature on the neurobiology of ASD. Information from this comparison is then used to formulate possible mechanisms by which exercise may reduce maladaptive behaviors in adults with ASD. Results: Plausible mechanisms for an exercise-induced beneficial effect on maladaptive behaviors in adults with ASD include modulation of neurotransmitter release and function, facilitation of endocannabinoid release, increased expression of neurotrophic factors, improved functional connectivity in higher-level cognitive networks, reduced oxidative stress, improved HPA axis function, treatment of comorbid depression, and reduction in amyloid beta deposition in cortical GABAergic neurons and subcortical structures. Conclusions: Future research should attempt to confirm the efficacy of exercise in reducing maladaptive behaviors in adults with ASD as well as the proposed mechanisms for such a relationship. Verification of these issues would have major implications in terms of supporting an evidence-based, inexpensive, widely available, and broadly beneficial treatment for adults with ASD.
Riqueza de especies, endemismo y evaluación del riesgo de extinción del género Bursera (Burseraceae) en la Península de Baja California
Authors: Sánchez-Romero Abraham , Aragón-Parada Juvenal
Published: May 2024

Background: Bursera is a genus native to tropical America and groups around 114 species. Western Mexico is its main center of diversification, and the south of the Baja California Peninsula is an important center of endemism for the genus.
Questions: How many species of Bursera are there in the Baja California Peninsula? Where are they distributed? Which is their status of conservation?
Studied species: The species of Bursera of the Baja California Peninsula.
Study site and dates: The Baja California Peninsula, Mexico; from 2021 to 2022.
Methods: A database was generated from electronic repositories, herbaria, field collections and specialized literature. Species richness was calculated by political division, biogeographic province, ecoregion, and a 40 × 40 km grid. Species distribution models were built, and the conservation status was estimated for each taxon using the IUCN B2 criterion.
Results: In the Baja California Peninsula 11 species of Bursera were documented, of which seven are endemic. Species richness was concentrated in the Cape Tropical Shrubland at elevations between 0 and 500 m. Five species were classified in some risk category.
Conclusions: The present work expands knowledge about the distribution and conservation status of Bursera in the Baja California Peninsula.
