Barriers to Reproductive Justice for Women Seeking Sanctuary in the UK: Narratives from Birth Companions and the Maternity Stream of Sanctuary
Authors: Brunton Katherine Miller , Waterfall Katherine
Published: September 2024

Women living in the UK with insecure immigration status are often from ethnic minority groups, have limited understanding of English, and have significant experience of trauma. Recent confidential inquiries into maternal deaths have repeatedly shown how intersecting and multiple disadvantage puts these women at higher risk of maternal mortality and morbidity. Multiple voluntary sector organisations are relied upon to support these women as they navigate the journey to parenthood. A reproductive justice framework is here employed to examine the multitude of factors intersecting to influence the access women with insecure migrant status have to maternity services. Narrative construction of three composite case studies took place to highlight the various ways reproductive justice is both violated and protected by the immigration and maternity systems in the UK. The discussion section comments on prevalent themes throughout each case study: gendered dynamics of insecure immigration status, structural barriers and complex systems, and reliance on the fragile voluntary sector. This article concludes that, alongside the work of the voluntary sector, women’s reproductive justice rights must also be emphasised and protected throughout statutory systems and services.

Published: September 2024

In the rapidly evolving real estate industry, integrating automated valuation models (AVMs) has become critical for improving property assessment accuracy and transparency. Although there is some research on the subject, no thorough qualitative systematic review has been done in this field. This paper aims to provide an up-to-date and systematic understanding of the strategic applications of AVMs across various real estate subsectors (i.e., real estate development, real estate investment, land administration, and taxation), shedding light on their broad contributions to value enhancement, decision-making, and market insights. The systematic review is based on 97 papers selected out of 652 search results with an application of the PRISMA-based method. The findings highlight the transformative role of AVMs approaches in streamlining valuation processes, enhancing market efficiency, and supporting data-driven decision-making in the real estate industry, along with developing an original conceptual framework. Key areas of future research, including data integration, ethical implications, and the development of hybrid AVMs approaches are identified to advance the field and address emerging challenges. Ultimately, stakeholders can create new avenues for real estate valuation efficiency, accuracy, and transparency by judiciously utilizing AVMs approaches, leading to more educated real estate investment decisions.

We present Crab X-ray polarization measurements using Imaging X-Ray Polarimetry Explorer (IXPE) data with a total exposure of 300 ks, three times more than the initial 2022 discovery paper. Polarization is detected in three times more pulsar phase bins, revealing an S-shaped +40° polarization angle sweep in the main pulse and >1σ departures from the OPTIMA optical polarization in both pulses, suggesting different radiation mechanisms or sites for the polarized emission at the two wavebands. Our polarization map of the inner nebula reveals a toroidal magnetic field, as seen in prior IXPE analyses. Along the southern jet, the magnetic field orientation relative to the jet axis changes from perpendicular to parallel and the polarization degree decreases by ∼6%. These observations may be explained by kink instabilities along the jet or a collision with a dense, jet-deflecting medium at the tip. Using spectropolarimetric analysis, we find asymmetric polarization in the four quadrants of the inner nebula, as expected for a toroidal field geometry, and a spatial correlation between polarization degree and photon index.
On the Cosmic Variance of the Merger Rate Density of Binary Neutron Stars
Authors: Chen Zhiwei , Lu Youjun , Wang Jie , Jiang Zhen , Chu Qingbo , Ma Xianghao
Published: September 2024

The cosmic variance on the star formation history may lead to bias in the merger rate density estimation of binary neutron star (BNS) mergers by compact binary population synthesis. In this paper, we take advantage of the large box size of the Millennium Simulation combined with the semianalytic galaxy formation model GABE and the parameterized population binary star evolution model to examine how much effect the cosmic variance will introduce on the estimation of the merger rate density of BNS mergers. We find that for subbox sizes of 100 and 200 Mpc, the variance of merger rate density σ

R
/R at different redshifts is about 23%–35% and 13%–20%, respectively. On the one hand, as for the variance of the detection rate on BNS mergers with the current LIGO–Virgo–KAGRA (LVK) detector network, this value is very small at ≲10%, which indicates ignoring the cosmic variance is reasonable for estimating the merger rate density from current LVK observations. On the other hand, with next-generation gravitational wave detectors, it is possible to localize BNS mergers within subboxes possessing a length of 40 Mpc for a source redshift z

s
< 0.2. In such a small box, the cosmic variance of the merger rate density is significant, i.e., the value of σ

R
/R is about ∼55%. This hints that estimating the merger rate density of BNS in different sky areas may provide useful information on the cosmic variance.

New results on the behavior of the double-mode RR Lyrae V338 Boo are presented. The Transiting Exoplanet Survey Satellite (TESS) observed this star again in 2022, and an observing campaign of the American Association of Variable Star Observers (AAVSO) was completed after the TESS observations as a follow-up. We find that the first overtone pulsation mode in this star completely disappears during the TESS observing window. This mode reappears at the end of the TESS observations, and the AAVSO observing campaign shows that in the months that followed, the first overtone mode was not only present but was the dominant mode of pulsation. This star, and potentially others like it, could hold the key to finally solving the mystery of the Blazhko effect in RR Lyrae.

Published: September 2024

Purpose

In dementia family caregiving, caregiver psychopathology has been frequently identified as a possible risk factor for the use of physically abusive, psychologically abusive, and neglectful behaviors toward care recipients. Yet, the mechanistic role of psychopathology in the use of these behaviors is not understood. The purpose of the current study is to determine the role of caregiver mental health in their daily risk of engaging in physically and psychologically aggressive and neglectful behaviors toward their care recipient with dementia.

Method

We used an intensive longitudinal design to survey family caregivers daily over 21 days. Using generalized linear mixed models, we evaluated the differential impact of caregivers' (
N
= 453) experience of major depression and generalized anxiety disorders measured at baseline versus 9,513 daily ratings of depressive and anxiety symptom severity, and interactions across levels, on the daily odds of engaging in physically abusive, psychologically abusive, and neglectful behaviors.

Results

Caregivers with clinically significant depression or anxiety at baseline had higher daily odds of engaging in each type of abusive and neglectful behavior. Worsened depressive symptoms (compared to individuals' average across all days) on a given day were associated with increased odds of engaging in psychologically and physically aggressive behaviors on the same day. Worsened anxiety symptoms on a given day were associated with increased odds of psychologically aggressive and neglectful behaviors.

Conclusion

A key finding was lack of a significant interaction effect between depression and anxiety disorders and mental health symptomology on the daily odds of engaging in abusive and neglectful behaviors. This finding indicates that daily depressive and anxiety symptoms are generalizable intervention targets across the family caregiver population and do not only increase risk among family caregivers with depressive and anxiety disorders.

Feasibility of a Culture-Based Multicomponent Cognitive Training Program for Older Adults With Dementia
Authors: Chen Ming-Hsin , Yu Ching-Len , Chang Su-Hsien
Published: September 2024

Purpose

To understand whether a culture-based multicomponent cognitive training program is feasible and tolerable for persons with dementia (PWD) in day care centers in Taiwan, and to examine the effectiveness of a 16-week program in preventing declines in cognitive function and self-care, as well as the development of depressed mood and behavioral problems.

Method

This study was a 4-month cluster randomized controlled trial. PWD (
N
= 56) who met sample selection criteria were recruited from five day care centers and assigned to the experimental or comparison group. Participants in the experimental group received a series of culture-based multicomponent cognitive training activities via research assistants and day care center caregivers for 16 weeks. Participants in the comparison group received usual daily activities. Time attending activities and degree of participation were used as criteria for determining feasibility and tolerability of the program.

Results

Results confirmed the feasibility of culture-based multicomponent cognitive training activities if the activities were guided by caregivers. Results also showed participants in the experimental group had statistically significant improvements in cognitive function. Activities of daily living performance, depressed mood, and behavioral problems showed non-significant improvements.

Conclusion

The current study suggests that this program can assist PWD in preventing declines in self-care and the development of behavioral and psychological problems, and improve their cognitive function. Further research with a larger sample size and staff training should be considered to test the effectiveness of this program. [

E-commerce user's intention to switch toward drone delivery innovation: The role of environmental concern and customers' attitude
Authors: Veronica Veronica , Arief Muhtosim , Furinto Asnan , Sanny Lim
Published: September 2024

Environmental concern is a determinant in acquiring new green innovation. We aimed to investigate the relationship between environmental concern, consumer attitude, and behavioral intention to switch in the context of drone delivery. The motivation that comes from a green perspective is believed to create a behavior that is also keen on innovative green products. One of the examples is the implementation of drones in delivering parcels, which is believed to cut the carbon footprint. Our purpose was to analyze the direct impact of environmental concern on consumers' behavioral intentions regarding e-commerce drone delivery. Additionally, we aimed to examine the mediating role of consumers' attitudes toward innovation in the relationship between environmental concern and behavioral intention. We sought to provide insights into how environmental awareness and the adoption of innovative delivery technologies like drones can influence consumer behavior, contributing to more sustainable and eco-friendly e-commerce practices. Structured questionnaires were provided to e-commerce users, reliability and validity tests were confirmed, and structural equation modeling (SEM) was used to analyze the relationships among variables. The results of the SEM analysis proved that environmental concern and consumer attitudes have a positive impact on behavioral intention. Customer attitude mediates the relationship between environmental concern and behavioral intention. This research provides a deeper understanding of how environmental concerns influence consumer behavior towards drone delivery innovation within the e-commerce sector. The implications integrate environmental concerns with consumer behavior and innovation adoption, providing a comprehensive view that goes beyond traditional marketing and consumer research.

O objetivo deste trabalho é realizar apontamentos sobre os limites à consolidação de um Estado de Bem-Estar Social no Brasil. Para isto, buscou-se compreender o contexto de sua origem e suas diferentes formas. O welfare state brasileiro erigiu com característica meritocrática-conservadora, voltado à pequena parcela da população. Por outro lado, a Constituição de 1988 engendra um Estado de Bem-Estar moderno buscando inserir a cidadania social como valor. Entretanto, o contexto é desfavorável e, embora haja avanços em sua implementação, limites estruturais e conjunturais impedem maior progresso.

Authors: Liu Wen Hui , Bolag Altan , Sun Yan Chao , Bao Ta Na
Published: September 2024

In this study, novel organic/inorganic composites were fabricated by blending anthraquinone (AQ) with SBA-15 molecular sieve in varying ratios via ultrasonication, characterized structurally using XRD, SEM, and BET methods, and analyzed electrochemically as cathode materials for lithium-ion batteries via galvanostatic discharge/charge and electrochemical impedance spectroscopy. The composite with a 2:1 ratio of AQ and SBA-15 achieved a specific discharge capacity of 144.5 mAh/g at 0.2 C, which decreased to 63.3 mAh/g after 50 cycles, 8% higher than that of the pure AQ. The initial discharge platform of the composite was 2.28 V, which decreased to 2.10 V after 50 cycles, 50 mV higher than that of the pure AQ. This is because the loading of anthraquinone particles by the SBA-15 pore size structure facilitated the stabilization of the active materials, hindered the solubility of AQ in the electrolyte, and enhanced the cycling stability of the battery.

Published: September 2024

A proposal has been presented for the regeneration of a spent sorbent mixture, comprising activated carbon (BAU-A brand) and kieselguhr (Bekogur 200 brand), in a mass ratio of 1:3. The effectiveness of the regeneration process and the potential applications of the spent sorbents were determined through X-ray phase analysis methods. The study included an investigation into the adsorption of the primary dye (methylene blue) by activated carbon and various sorbent mixtures. The observed efficiency of regeneration supports the recommendation of using a combination of kieselguhr and activated carbon sorbents for treating wastewater in food industry enterprises.

Published: September 2024

Abrasives play a crucial role in surface blasting, especially in cold climates, where snow and ice significantly challenge transportation infrastructure and road safety. The main purpose of this research is to address the critical need for effective and sustainable winter maintenance techniques. This study examined the possibilities of Basic Oxygen Furnace Slag (BOFS) as a substitute (an abrasive substance) for conventional aggregates in ice-melting applications. Thus, this research assessed the physical properties of BOFS, such as absorption capacity, tested at -5°C, and aggregate angularity test, and designed for evaluation of the surface texture, friction, and percentage of fractured faces in uncompacted voids (SSD%) of the aggregates. Moreover, the potential use of a blend of BOFS with de-icing salts, specifically sodium chloride (NaCl) and calcium chloride (CaCl2), was investigated as an effective ice-melting agent. For this purpose, three tests were carried out: the petri dish test according to SHRP H-205.1, the polishing ice melting test using a modified ASTM C 944 (rotational cutter), and the surface temperature measurement test. By assessing the performance of BOFS, our goal was to justify its efficacy, offering a practical alternative for regions experiencing severe winter conditions. Eventually, the findings from this study assert that BOFS can be used for surface blasting, indicating its potential as a substitute for traditional abrasives.

Published: September 2024

In the search for environmentally acceptable and sustainable energy storage solutions, biomass-derived biochar materials are becoming popular in supercapacitor applications. Rice straw is regularly disposed of as agricultural waste, but it is an intriguing biomass precursor for synthesizing activated biochar suitable for supercapacitor electrodes. This study exhibited the utilization of activated biochar synthesized from rice straw through pyrolysis and potassium hydroxide (KOH) activation for supercapacitor applications. Structural examination, such as X-ray diffraction (XRD), transmission electron microscopy (TEM), and nitrogen (N2) adsorption and desorption, showed the activated rice straw-derived biochar‘s distinct crystal structure, morphological structure, pore structure, and surface area. Rice straw-derived biochar revealed an amorphous structure, nanosheet-like or multilayered morphology, and hierarchical pore structure. Electrochemical characterization showed that the activated rice straw-derived biochar has high specific capacitances of 116.48 F/g at 1 A/g and 84.58 F/g at 5 A/g, respectively. The amorphous character, hierarchical pore structure, and nanosheet-like morphology of the rice straw-derived biochar provided favorable properties for effective ion transfer for high electrochemical performance. These findings exhibited the prospects of rice straw as a sustainable and economical biomass precursor to produce excellent electrode material in supercapacitor applications.

However, no significant difference was observed against MSSA and E. faecalis.Conclusion: The findings suggest that P. guajava extract could potentiate the efficacy of procaine penicillin against MRSA, providing a potential alternative strategy to combat antibiotic-resistant bacteria.Contribution: The study revealed that P. guajava aqueous extract enhances the antibacterial efficacy of procaine penicillin specifically against MRSA, suggesting a potential alternative treatment strategy for antibiotic-resistant infections, validated through robust methods and highlighting the need for further research to understand the mechanisms and clinical applications.
Sequences of independent functions and structure of rearrangement invariant spaces
Authors: Astashkin Sergei Vladimirovich
Published: September 2024

The main aim of the survey is to present results of the last decade on the description of subspaces spanned by independent functions in $L_p$-spaces and Orlicz spaces on the one hand, and in general rearrangement invariant spaces on the other. A new approach is proposed, which is based on a combination of results in the theory of rearrangement invariant spaces, methods of the interpolation theory of operators, and some probabilistic ideas. The problem of the uniqueness of the distribution of a function such that a sequence of its independent copies spans a given subspace is considered. A general principle is established for the comparison of the complementability of subspaces spanned by a sequence of independent functions in a rearrangement invariant space on $[0,1]$ and by pairwise disjoint copies of these functions in a certain space on the half-line $(0,\infty)$. As a consequence of this principle we obtain, in particular, the classical Dor-Starbird theorem on the complementability of subspaces spanned by independent functions in the $L_p$-spaces.

Разреженное восстановление в некоторых функциональных классах в интегральных нормах
Authors: Temlyakov Vladimir Nikolaevich
Published: September 2024

Эта работа является прямым продолжением недавних работ автора. В этой работе мы продолжаем анализировать свойства аппроксимации и восстановления по системам, удовлетворяющим условию универсальной дискретизации по значениям в точках и специальному условию безусловности. Кроме того, мы предполагаем, что подпространство, натянутое на нашу систему, удовлетворяет некоторым неравенствам Никольского. В основном мы изучаем восстановление с ошибкой, измеренной в норме $L_p$ для $2\le p<\infty$. Мы применяем мощный нелинейный метод приближения - алгоритм слабого ортогонального преследования (АСОП) (Weak Orthogonal Matching Pursuit (WOMP)), который также известен под названием слабый ортогональный жадный алгоритм (СОЖА) (Weak Orthogonal Greedy Algorithm (WOGA)). Мы устанавливаем, что АСОП, основанный на точках, которые дают хорошую универсальную дискретизацию в $L_2$, обеспечивает хорошее восстановление в норме $L_p$ для $2\le p<\infty$. Для наших алгоритмов восстановления мы получаем как неравенства Лебега для индивидуальных функций, так и оценки ошибок для специальных функциональных классов функций многих переменных.
В этой работе для того, чтобы получить новые результаты о восстановлении по выборке (по значениям в точках), мы одновременно используем два глубоких и мощных метода: неравенства типа Лебега для АСОП и теорию универсальной дискретизации по значениям в точках.

Multiscale implicit frequency selective network for single‐image dehazing
Authors: Wang Zhibo , Jia Jia , Min Jeongik
Published: September 2024

Image dehazing is aimed to reconstruct a clear latent image from a degraded image affected by haze. Although vision transformers have achieved impressive success in various computer vision tasks, the limitations in scale and quality of available datasets have hindered the transformer effectiveness for image dehazing. Thus, convolutional neural networks (CNNs) remain the mainstream approach for image dehazing, offering robust performance and adaptability. We further explore the potential of CNNs in image dehazing by proposing a multiscale implicit frequency selection network (MIFSN). The proposed MIFSN enhances multiscale representation learning based on U‐shaped networks. As hazy and clear images considerably differ in high‐frequency components, we introduce an implicit frequency selection module to amplify high‐frequency components of features and generate candidate feature maps. Implicit frequency selection attention is then used to emphasize and merge beneficial frequency components. Results from extensive experiments on synthetic and real‐world datasets demonstrate the superior performance of MIFSN for image dehazing.

Published: September 2024

Objective: This study aimed to determine the working conditions of the robotic surgery nurses in Turkey.
Method: In this descriptive study, data was collected between May 2020 to January 2021. Nurses who were working in robotic surgery for at least one year in 32 hospitals in different eight cities, were included in the study (n=90). Data were collected with the Sociodemographic and Working Conditions Form of Nurses electronically.
Results: The mean age of nurses working in the field of robotic surgery was 32.03±6.52 years and 80% of them were female. 50% of the nurses didn’t receive any education about robotic surgery, 50% of the nurses stated that the nursing roles were not clear, 44.4% of the nurses consider their level of knowledge partially sufficient, 58.9% of them did not have a written procedure, 76.7% of them feeling anxious during the surgery. There was a statistically significant difference between the age (p=0.046), gender (p=0.005), marriage (p=0.013), experiencing problem during surgery (p=0.007), self-assessment knowledge (p=0.038), had flow charts/checklists (p=0.010), regular in-service education (p=0.022) and nurses' feeling anxious during surgery.
Conclusion: In this study, more than half of robotic surgery nurses experienced problems in during surgery. The most common problems were lack of knowledge, ambiguity of roles and responsibilities, staff shortages and lack of English language skills. It is recommended to develop national and institutional procedures to ensure patient safety in robotic surgery, to eliminate the uncertainty regarding the roles of nurses, to determine nurse competencies and to contribute to the education of nurses in this field.
Refik Anadol’s AI-Based Digital Art and Its Intellectual Connotations
Authors: Oktan Ahmet , Akyol Oktan Kevser
Published: September 2024

This article delves into the digital art produced by the internationally renowned Turkish artist Refik Anadol and his team, emerging at the intersection of diverse disciplines such as mathematics, physics, computer science, and aesthetics, within the context of its intellectual connotations. This qualitative study encompasses 26 projects featured on the Refik Anadol Studio’s website. In addition to the projects, we utilize as data sources the videos, visuals and texts that are available on the website, Anadol’s social media posts, audience comments, interviews, academic articles, and news and critiques related to his works. We analyze the works in the context of the artistic creation process, the nature of the technological collaboration, the relationship established with memory, time, space and audience, particularly in the context of the meanings they signify, and we assess the data we obtain along with their philosophical connections. In short, Anadol transforms public data such as images, sounds, and social media posts that constitute collective memory into art with the aid of digital technology capabilities, especially artificial intelligence, creating in these works molecular, fluid, transient intermediate spaces by superimposing different temporal and spatial layers, images, and realities. Through art, he opens up for discussion questions such as what is the position of the artist in the age of artificial intelligence; how art can help us understand the relationship between the virtual and the real; and what it means to experience memory in the digital age. The heterotopic spaces he constructs in his works offer utopian imagery which suggests a life based on peace, optimism, and relationship shared among humans, nature, and other forms of existence.
Analysis of Profiles of Supporters of Conspiracy Narratives about Vaccination Against COVID-19 on a Social Network
Authors: Sarkisova Anna Yu. , Dunaeva Daria O. , Petrov Evgeny Yu. , Voronov Aleksandr S.
Published: September 2024

The article analyzes the socio-demographic characteristics and value-worldview self-positioning of the distributors of conspiracy narratives (“conspiracy theories”) about vaccination against COVID-19 on the Russian social network “VK”. The research material consists of 33,674 profiles of VK users who published at least two messages during the pandemic that explicate the stated narrative. The collection and analysis of the material was carried out using big data analysis technologies. The purpose of the study is to determine whether it is possible to identify typical socio-demographic and ideological traits of anti-vaccer conspiracy theorists, which to a certain extent explain their penchant for conspiracy thinking. The results obtained refute the marginal dominance of conspiracy theorists in a pandemic situation. Versions popular in the scientific literature about the predominance of insufficiently educated people among “conspiracy theorists”, or the elderly as more gullible, or women as more suggestible, or residents of villages and small provincial towns as more conservative, etc. are not confirmed by the large-scale empirical studies of large user data. The results of the study may be useful for developing countermeasures and strategies to address public mistrust of institutions and official trends in public health, in particular vaccination policies. The traditional focus on information and educational measures (explanations about the dangers of the disease and the benefits of the vaccine) seems to be ineffective in the context of the emergence of value systems, cognitive distortions, general socio-political tension and other reasons that are still awaiting serious study.
Ritual, Media, and Alienation: Three Cases of Constructing the Image of a School Shooter in Russian Media in the Context of the Ritual of Chiral Initiation
Authors: Aliev Rastyam T.
Published: September 2024

Mass school shootings in Russia have become a symbol of deep social and cultural dysfunctions, reflecting a crisis of identity and youth alienation. The paper emphasizes the importance of exploring how the media constructs the image of a school shooter, influencing public perception and the perception of the perpetrators themselves. The media’s role in intensifying the alienation and marginalization of shooters through the ritualization and narrativization of acts of violence requires in-depth analysis. The aim of the study is to analyze the phenomenon of school shootings through the lens of the ritual of chiral initiation and to identify the sociocultural factors contributing to the construction of the shooter’s image.
The analysis shows that media coverage of school shootings follows a ritualized script that reinforces the perception of the shooter as an alienated and dangerous individual, cementing his marginal status. The “Non-Return” stage in the chiral initiation ritual illustrates the shooter’s irreversible break from society and self-identity. The study underscores the need for a comprehensive analysis of the media and cultural factors shaping public opinion about school shooters.
The target audience of this study includes scholars in sociology, cultural studies, and anthropology, as well as professionals involved in media studies and public safety.

A partir da aplicação dessa proposta e da análise dos dados, verificou-se a integração da avaliação diagnóstica, formativa e somativa em diversas etapas do trabalho através da Resolução de Problemas, que contribuiu para a aprendizagem e a construção do conhecimento em um ambiente democrático e colaborativo.
Reino e território: Templo de Salomão e as tecnologias de ocupação urbana da Igreja Universal
Authors: Teixeira Jacqueline Moraes
Published: September 2024

Este artigo descreve a Igreja Universal, sua performance de ocupação urbana, suas estratégias de visibilidade e de materialidade do sagrado por meio de suas pedagogias gestoras de população e por suas estratégias de ocupação dos espaços urbanos, algo que resulta, no ano de 2014, na construção do Templo de Salomão. A hipótese geral que orienta esta reflexão é de que, ao contrário do que comumente se imagina, religiões não produzem religiosos, igrejas não produzem fiéis. E sim, de que constituem máquinas de produção incessante de corpos civis ao incitar determinadas pedagogias eróticas, bem como a regulação da afetividade e das relações de gênero e do sexo. Esta abordagem abre margem para se possa pensar, e este é o principal objeto deste trabalho, a intersecção entre processos de subjetivação, poder pastoral e esfera política.
Modelagem Espacial Dinâmica para a concepção de cenários prospectivos de uso e cobertura da terra no município de Araraquara – SP

Published: September 2024

O presente artigo buscou analisar de quais formas uma modelagem espacial dinâmica pode contribuir com as questões relacionadas ao ordenamento territorial, discorrendo sobre as possibilidades oriundas da prospecção de cenários de uso e cobertura da terra futuros tendo como estudo de caso o município de Araraquara-SP. O modelo foi elaborado fazendo uso do plugin MOLUSCE, presente na plataforma QGIS, utilizando os mapeamentos do projeto Map Biomas (SOUZA, 2020) para os anos de 2000, 2010 e 2020 adotando o método das Redes Neurais Artificiais para gerar o potencial de transição entre os usos e cobertura da terra e um modelo autômato-celular na abordagem Monte Carlo (LIU, et al. 2001), prospectando um cenário para o ano de 2030. Os resultados dos modelos de transição foram satisfatórios, onde o valor Kappa obtido foi de 0,72 para o período de 2000–2010 e 0,68 para o período de 2010–2020. Fazendo uso do mapa de uso inicial, de referência e o mapa simulado de foi feita análise pelo MOLUSCE, indicando um Kappa de 0,65 para a prospecção feita pelo modelo. Conclui-se que o MOLUSCE projetou um cenário que pode auxiliar os gestores públicos no ordenamento e planejamento territorial de Araraquara para o ano de 2030, levando em consideração as informações que calibraram o modelo, demonstrando inclusive que a ferramenta pode ser utilizada para outros estudos de caso.

Os alongamentos são comumente empregados antes da prática esportiva, visando o aprimoramento do desempenho. No entanto, as evidências são divergentes sobre os benefícios para o desempenho esportivo. Assim, o presente estudo objetivou sistematizar os principais achados sobre os efeitos de diferentes protocolos de alongamento dos isquiotibiais no desempenho de jogadores de futebol. Trata-se de uma revisão sistemática, que reuniu artigos científicos das bases de dados eletrônicas PubMed/Medline, ISI Web of Science e Scopus. Os artigos selecionados foram da língua inglesa, tendo como descritores: "stretching", "hamstring" e "performance", sendo cruzados a modalidade esportiva “soccer”. O operador booleano “and” foi empregado para limitar a pesquisa. No estudo foram considerados ensaios clínicos, ensaios clínicos cruzados e ensaios clínicos aleatórios, que abordaram os efeitos dos alongamentos de isquiotibiais no desempenho do futebol, em atletas amadores e de alto rendimento, sem restrição de datas. Inicialmente, 107 registros foram identificados. Após análise de títulos e resumos, 70 foram excluídos. A remoção de duplicatas reduziu para 19 artigos, e após análise detalhada, 13 estudos foram selecionados para a revisão. Os alongamentos mais prevalentes dos protocolos nas investigações foram os estáticos (92,31%) e dinâmicos (30,77%). As principais medidas de desempenho abordadas nos estudos incluíram flexibilidade, velocidade, força e salto. Conclui-se que de forma geral os alongamentos aprimoram a flexibilidade. Além disso, a maioria dos estudos evidenciaram que os alongamentos estáticos promovem efeitos negativos para a velocidade, enquanto os efeitos dos alongamentos dinâmicos permanecem inconclusivos. Em relação à força, a maioria dos estudos demonstraram que ambos os tipos de alongamentos, estáticos e dinâmicos, não interferem no desempenho do futebol. Por fim, a influência dos alongamentos estáticos no salto demonstrou ser variável, enquanto a maioria dos estudos que analisaram alongamentos dinâmicos demonstram não haver influência nessa capacidade, sendo que, em alguns estudos, foram observados efeitos positivos na impulsão.
