Authors: Wenjie Lu , Jiaming Zhang , Weiyu Jiang
Published: July 2023

Objective

This study aimed to evaluate the feasibility of the modified thoracolumbar injury classification and severity score system in guiding clinical treatment.

Methods

A retrospective study was conducted on a cohort of 120 patients with thoracolumbar fractures who were admitted to the Department of Spinal Surgery at Ningbo Sixth Hospital between December 2019 and June 2021. The study population consisted of 68 males and 52 females, with an average age of 36.7 ± 5.7 years. The severity of the fractures was assessed based on comprehensive scores incorporating fracture morphology, neurological function, posterior ligament complex integrity, and disc injury status. The evaluation was performed using the total score T, which guided the formulation of the clinical treatment strategy. Furthermore, the study compared the treatment options, imaging data, and clinical efficacy between two classification systems.

Results

The analysis of 120 patients revealed no statistically significant difference in the total score or treatment method between the TLICS system and the modified TLICS system. However, the operation rate for the modified TLICS system (73.3%) was slightly lower compared to the TLICS system (79.2%). All patients were followed up for a mean duration of 19.2 ± 4.6 months, ranging from 11 to 27 months. At the last follow-up, the visual analogue scale score was 1.94 ± 0.52, and the modified Japanese Orthopaedic Association score was 28.8 ± 4.5, indicating a significant improvement compared to the scores obtained prior to treatment. The neurological status exhibited varying degrees of improvement. Notably, the anterior vertebral height ratio was 87.10 ± 7.17%, the sagittal index was 90.35 ± 7.72%, and the Cobb angle was 3.05 ± 0.97 degrees at the last follow-up. All these measurements demonstrated statistically significant differences compared to the values observed prior to treatment (P < 0.05). Additionally, two cases of pedicle screw breakage and seven cases of pedicle screw wear and cutting in the vertebral body were observed at the last follow-up, resulting in varying degrees of low back pain. However, no instances of rod breakage were reported.

Conclusion

The modified TLICS system is a practical tool for the classification and assessment of thoracolumbar fractures. It has guiding significance for clinical treatment, and the operation rate was slightly lower than that of TLICS system.

Published: July 2023

Background

In veterinary clinical practice, orchiectomy is one of the most common surgical procedures for cats and is performed mainly in young animals. The purpose of this study was to compare three different epidural (EP) analgesic protocols used in cats undergoing orchiectomy in order to determine which protocol resulted in superior outcomes in terms of perioperative analgesia. Twenty-one client-owned male cats were premedicated with a combination of dexmedetomidine (10 µg/kg) and midazolam (0.2 mg/kg) injected intramuscularly. Anesthesia was induced intravenously with propofol. Cats were randomly divided in three treatment groups of seven animals each: Group L received EP lidocaine (2 mg/kg), Group T received EP tramadol (1 mg/kg), and Group LT received EP lidocaine (2 mg/kg) plus tramadol (1 mg/kg). The post-operative pain level was assessed using two different scales: the Glasgow Composite Measure Pain Scale-Feline (CMPS-F) and the Feline Grimace Scale (FGS). Rescue analgesia was administered when the CMPS-F total score was ≥5 or the FGS total score was ≥4.

Results

No adverse effects related to tramadol or lidocaine were observed. Based on post-operative pain assessments, significant differences between groups were observed according to both pain scoring systems. In particular, in Group LT, the CMPS-F and FGS scores decreased significantly in the first six hours following castration.

Conclusions

Based on our results, EP lidocaine plus tramadol provided the best post-operative analgesic effects in cats submitted to orchiectomy lasting 6 h and could also be a choice to consider for longer surgical procedures.
Development of the livestock pathogen Trypanosoma (Nannomonas) simiae in the tsetse fly with description of putative sexual stages from the proboscis
Authors: Peacock Lori , Kay Chris , Collett Clare , Bailey Mick , Gibson Wendy
Published: July 2023

Background

Tsetse-transmitted African animal trypanosomiasis is recognised as an important disease of ruminant livestock in sub-Saharan Africa, but also affects domestic pigs, with Trypanosoma simiae notable as a virulent suid pathogen that can rapidly cause death. Trypanosoma simiae is widespread in tsetse-infested regions, but its biology has been little studied compared to T. brucei and T. congolense.

Methods

Trypanosoma simiae procyclics were cultured in vitro and transfected using protocols developed for T. brucei. Genetically modified lines, as well as wild-type trypanosomes, were transmitted through tsetse flies, Glossina pallidipes, to study T. simiae development in the tsetse midgut, proventriculus and proboscis. The development of proventricular trypanosomes was also studied in vitro. Image and mensural data were collected and analysed.

Results

A PFR1::YFP line successfully completed development in tsetse, but a YFP::HOP1 line failed to progress beyond midgut infection. Analysis of image and mensural data confirmed that the vector developmental cycles of T. simiae and T. congolense are closely similar, but we also found putative sexual stages in T. simiae, as judged by morphological similarity to these stages in T. brucei. Putative meiotic dividers were abundant among T. simiae trypanosomes in the proboscis, characterised by a large posterior nucleus and two anterior kinetoplasts. Putative gametes and other meiotic intermediates were also identified by characteristic morphology. In vitro development of proventricular forms of T. simiae followed the pattern previously observed for T. congolense: long proventricular trypanosomes rapidly attached to the substrate and shortened markedly before commencing cell division.

Conclusions

To date, T. brucei is the only tsetse-transmitted trypanosome with experimentally proven capability to undergo sexual reproduction, which occurs in the fly salivary glands. By analogy, sexual stages of T. simiae or T. congolense are predicted to occur in the proboscis, where the corresponding portion of the developmental cycle takes place. While no such stages have been observed in T. congolense, for T. simiae putative sexual stages were abundant in the tsetse proboscis. Although our initial attempt to demonstrate expression of a YFP-tagged, meiosis-specific protein was unsuccessful, the future application of transgenic approaches will facilitate the identification of meiotic stages and hybrids in T. simiae.

Graphical Abstract
LncRNA00638 promotes the osteogenic differentiation of periodontal mesenchymal stem cells from periodontitis patients under static mechanical strain
Authors: Zhang Xiaochen , Yan Qing , Liu Xulin , Gao Jie , Xu Yuerong , Jin Zuolin , Qin Wen
Published: July 2023

Background

The osteogenic differentiation capacity of periodontal mesenchymal stem cells (PDLSCs) can be influenced by different levels of static mechanical strain (SMS) in an inflammatory microenvironment. Long non-coding RNAs (lncRNAs) are involved in various physiological processes. However, the mechanisms by which lncRNAs regulate the osteogenic differentiation of PDLSCs remain unclear.

Methods

We investigated the responses of PDLSCs obtained from periodontitis patients and healthy people to 8% and 12%SMS. Gene microarray and bioinformatics analyses were implemented and identified lncRNA00638 as a target gene for the osteogenesis of PDLSCs from periodontitis patients under SMS. Competing endogenous RNA (ceRNA) network analysis was applied and predicted interactions among lncRNA00638, miRNA-424-5p, and fibroblast growth factor receptor 1 (FGFR1). Gene expression levels were regulated by lentiviral vectors. Cell Counting Kit-8 assays, alkaline phosphatase assays, and Alizarin Red S staining were used to examine the osteogenic potential. RT-qPCR and Western blot were performed to detect the expression levels of related genes and proteins.

Results

We found that 8% and 12% SMS exerted distinct effects on HPDLSCs and PPDLSCs, with 12% SMS having the most significant effect. By microarray analysis, we detected differentially expressed lncRNAs/mRNAs between 12% SMS strained and static PPDLSCs, among which lncRNA00638 was detected as a positive target gene to promote the osteogenic differentiation of PPDLSCs under SMS loading. Mechanistically, lncRNA00638 may act as a ceRNA for miR-424-5p to compete with FGFR1. In this process, lncRNA00638 and miR-424-5p suppress each other and form a network to regulate FGFR1.

Conclusions

Our findings demonstrate that the lncRNA00638/miRNA-424-5p/FGFR1 regulatory network is actively involved in the regulation of PDLSC osteogenic differentiation from periodontitis patients under SMS loading, which may provide evidence for optimizing orthodontic treatments in patients with periodontitis.

Published: July 2023

Background

Systematic reviews summarize and evaluate relevant studies to contribute to evidence-based practice. Internationally, researchers have reached a consensus that the active involvement of the public leads to better research. Despite this agreement, there are many reviews of research concerning healthcare interventions intended to promote the care of people living with dementia and those from their social network (e.g., close contacts, both family and non-family members) primarily involve only healthcare professionals and other experts. Due to the lack of a dementia-sensitive framework to actively involve people living with dementia and those from their social network, and healthcare professionals as co-researchers in systematic reviews, it is important to develop a framework to inform practice.

Methods

For this framework development process, we will recruit four people living with dementia and a total of four people from their social network, and three healthcare professionals working in acute or long-term care settings. We will conduct regular meetings with these groups of the public and healthcare professionals to include them in all stages of the systematic review. We will also identify and develop methods necessary to ensure meaningful involvement. The results will be documented and analyzed for the development of a framework. For the planning and preparation for these meetings, as well as the conduct of the meetings themselves, we will be guided by the principles of the INVOLVE approach. In addition, the ACTIVE framework will be used to guide the degree of involvement and the stage in the review process.

Discussion

We assume that our transparent approach to the development of a framework to support the active involvement of people living with dementia and those from their social network, and healthcare professionals in systematic reviews will serve as an impetus for and provide guidance to other researchers with the goal of increasing researchers’ focus on this topic and facilitating systematic reviews that apply participatory approaches.

Authors: Saadia Sheema , Sultan Fateh Ali Tipoo , Iqbal Sara , Fatimi Saulat Hasnain , Nasir Aiysha
Published: July 2023

Background

Aorto-cavitary fistula is a rare complication of infective endocarditis. Multimodal imaging is commonly required to assess the severity and extent of infection because of the complex pathology of the valvular and paravalvular apparatus in endocarditis.

Case presentation

We present an unusual case of a middle-aged man with recent history of meningoencephalitis who developed infective endocarditis complicated by ruptured abscess in inter-valvular fibrosa between aortic and mitral valve resulting in free communication or fistula formation between aorta and left atrium. Patient underwent double valve replacement (aortic and mitral) along with repair of the aorta.

Conclusions

Our case highlights recognition of this rare clinical presentation of aorto-left atrial fistula in infective endocarditis and the diagnostic role of transesophageal echocardiography in good clinical outcome with aggressive and timely management.
A class-rebalancing self-training semisupervised learning for imbalanced data lithology identification
Authors: Yin Shitao , Lin Xiaochun , Zhang Zhifeng , Li Xiang
Published: July 2023

Lithologic identification plays a crucial role in petroleum geologic exploration, and machine learning (ML) has become increasingly prevalent in intelligent lithology identification in recent years. However, identifying lithologies presents challenges due to a lack of lithologic labels and an imbalanced distribution of lithologies. To address this issue and obtain satisfactory lithologic identification results, this study investigates a class-rebalancing self-training (CReST) lithology identification framework. This framework uses logging data and limited lithologic labels as input and achieves promising lithology classification through the CReST approach. Four ML algorithms with high overall performance are selected from 25 common algorithms to establish CReST models, such as bagging classifier, extra trees classifier, random forest classifier, and support vector classifier. The classification results of the models are compared and analyzed under three conditions. The experimental findings indicate that (1) under label scarcity, the effect of category recognition varies greatly with different sample numbers; (2) under self-training (ST), overall performance is improved, but the difference in performance caused by category imbalance also increases; and (3) under CReST framework, the model effectively resolves the identification problems caused by a lack of labels and an imbalanced category distribution. Specifically, the precision of identifying categories with fewer samples is improved by more than 20%.

Τα ευρήματα έδειξαν ότι σε υψόμετρα πάνω από 5500 μέτρα, η ποιότητα του ύπνου και η μεταβλητότητα του καρδιακού παλμού σταδιακά μειώνονται. Ολοκληρώνοντας, αναπτύχθηκε ένα διαδικτυακό εργαλείο το FL-WebPHS. Ακολουθώντας τα πρότυπα ISO 7933:2018 είναι σε θέση να εκτιμήσει το θερμικό στρες σε διάφορες περιβαλλοντικές συνθήκες. Συνοπτικά, αυτή η διατριβή βελτίωσε σημαντικά την κατανόηση του πώς διάφορες τεχνολογίες μπορούν να βελτιστοποιήσουν την ανθρώπινη απόδοση και να προστατεύσουν την υγεία σε διάφορες περιβαλλοντικές συνθήκες, δημιουργώντας τα θεμέλια για μελλοντική έρευνα και τεχνολογικές εξελίξεις γύρω από αυτούς τους τομείς.
Transitions to Second Birth and Birth Intervals in France and Spain: Time Squeeze or Social Norms?
Authors: Compans Marie-Caroline , Beaujouan Eva , Suero García Cristina
Published: July 2023

As first births are increasingly postponed across Europe, a strong two-child family norm persists. Past research has examined educational differentials in progressions to second birth, testing various hypotheses but overlooking normative aspects. Comparing fertility surveys from France and Spain, we explore whether late first-time mothers, who have fewer reproductive biological years left to conceive, accelerate the transition to a subsequent child (time squeeze effect). We also consider a normative dimension, i.e., whether women have their first child earlier or later than others in their educational and cohort groups. In both countries, among first-time mothers between 25 and 34 years of age, highly-educated women transitioned to second birth more frequently than less-educated women did. Within the same age group, highly-educated women in Spain had a second child more quickly after the firstborn than their less educated counterparts did, while there is no such difference in France. These results hold after controlling for cohort effects, but are only partly explained by a time squeeze effect. Different normative ages at first birth by education and birth cohort explain the educational gap in the likelihood of transitioning to second birth, but not the birth intervals in Spain. In sum, our analysis demonstrates a persistent educational gap in second births in this country that cannot be reduced to biological or normative effects. This suggests that a broad range of economic constraints play a role, such as unfavourable individual economic conditions and lower levels of institutional support for parenthood.

Published: July 2023

The Bharatavani project, launched in 2016 initiated by the Government of India, addresses the crucial need to preserve and promote indigenous languages and cultures. The paper presents an overview of the project, which focuses on recording socio-cultural and linguistic information about 121 Indian languages and making it accessible to a broader audience. The project leverages technological advancements to document significantly smaller and lesser-known languages and mother tongues in India, to raise awareness and maintain and promote the country's rich linguistic diversity. The Bharatavani project aims to bridge the digital divide and ensure equal access to knowledge and information by emphasizing the importance of incorporating these languages into the digital sphere. Through the creation of e-content, the project offers multimedia resources, including text, audio, video, and images, through the online portal www.bharatavani.in and the Bharatavani Android App. This research highlights the significance of content generation, software development, and web portal creation for selected languages in the first phase, with subsequent plans for translation, online teaching-learning, and language teacher training in the second phase. By embracing the potential of technology, the Bharatavani project aspires to create a Knowledge Society in the digital era, enabling individuals across India to explore and celebrate their linguistic heritage.
Multiperspectivity and Neutrality in Language Archives
Authors: Weber Tobias
Published: July 2023

This paper discusses linguistic data and their creation with a focus on the human actions and decisions that shape them. The human factor and positionalities are often obscured by current practices in data handling. Obscuring the human agency does not only reduce the transparency of the research but also disenfranchises the humans behind the data. The language archive takes a dual role as a host for discourse and an agent within it. It cannot claim impartiality but adds perspectives to research data and narratives.
LAS LECCIONES DEL PRONUNCIAMIENTO. EL OCASO DE NUEVA ESPAÑA, ENTRE LAS REVOLUCIONES DE RIEGO E ITURBIDE.
Authors: Espinosa Aguirre Joaquín E.
Published: July 2023

Los procesos de las primeras dos décadas del siglo XIX en el mundo hispánico fueron paralelos y estuvieron interrelacionados íntimamente. Muestra de ello es el pronunciamiento de Rafael del Riego, que tuvo una gran influencia no solo en el mundo mediterráneo, sino también en el proyecto que Agustín de Iturbide llevó a cabo en la primavera de 1821, cuando condujo a la Nueva España a su emancipación a través de un movimiento que distaba mucho del insurgente, llamando a la reconciliación, pero teniendo a su vez las armas como principal herramienta de negociación.

Published: July 2023

La segregación de los trabajadores de cuello blanco y de cuello azul es un fenómeno laboral que depende del tipo de tareas que realizan. Con la Encuesta Nacional de Empleo Urbano (eneu) 1996 y la Encuesta Nacional de Ocupación y Empleo (enoe) 2019 se lleva a cabo un estudio de la segregación laboral. En primer lugar, se presentan algunos indicadores sobre la segregación existente en el país, para posteriormente efectuar la descomposición de Oaxaca-Blinder sobre las probabilidades de segregación laboral estimadas. Los resultados indican que los fundamentos de la segregación laboral, el nivel de atracción o concentración de trabajadores de cuello azul en actividades rutinizadas, superan el grado de expulsión o rechazo de las actividades no rutinizadas.
The characteristics of successful military IT projects: a cross-country empirical study
Authors: Berg Helene , Ritschel Jonathan D.
Published: July 2023

In the armed forces, successful digitalization is crucial to ensure effective operations. Much of the existing literature on project factors during the planning and execution phases of public IT projects do not focus specifically on military sector projects. Therefore, the paper aims to provide empirical insights into the characteristics of successful military IT projects. Data from such projects in NATO countries and agencies were collected through interviews and project documents. The findings relating to the main variable of interest, “delivery of client benefit,” supported previous findings on IT project performance. Medium-sized projects performed better than small and large projects, and the agile development method delivered more client benefit than traditional methods. Client involvement apparently had a positive effect on project success. Clearly specified objectives had a statistically significant effect on project success in terms of clients’ benefits. The paper contributes to the gap in research on military IT projects and broadens the project management literature’s focus on time and cost to include delivery of client benefit as a success variable. The use of cross-country data provided unique insights for academics and practitioners regarding which project characteristics affect the successful development and adoption of new software by the armed forces.
Software developers reasoning behind adoption and use of software development methods – a systematic literature review
Authors: Havstorm Tanja Elina , Karlsson Fredrik
Published: July 2023

When adopting and using a Software Development Method (SDM), it is important to stay true to the philosophy of the method; otherwise, software developers might execute activities that do not lead to the intended outcomes. Currently, no overview of SDM research addresses software developers’ reasoning behind adopting and using SDMs. Accordingly, this paper aims to survey existing SDM research to scrutinize the current knowledge base on software developers’ type of reasoning behind SDM adoption and use. We executed a systematic literature review and analyzed existing research using two steps. First, we classified papers based on what type of reasoning was addressed regarding SDM adoption and use: rational, irrational, and non-rational. Second, we made a thematic synthesis across these three types of reasoning to provide a more detailed characterization of the existing research. We elicited 28 studies addressing software developers’ reasoning and identified five research themes. Building on these themes, we framed four future research directions with four broad research questions, which can be used as a basis for future research.
An agile portfolio management model for the insurance sector: the APMI model
Authors: Dias Vasco Franqueira , Tenera Alexandra B.
Published: July 2023

Nowadays, the increasing uncertainty and instability make it crucial for traditional companies to become more agile and able to act fast on consumer needs and expectations. Therefore, many insurance companies are seeking to increasingly adopt Agile practices to become more effective, faster, and leaner in their critical processes. On the other hand, several companies are strengthening their planning methodologies by implementing Portfolio Management models. These models enable them to manage their initiatives in a more integrated and efficient manner that is strategically aligned, minimizes complexity, and provides higher flexibility when responding to uncertainty. Given the limited scientific knowledge in combining Agile and Portfolio Management (PfM), particularly in the insurance industry, a new Agile Portfolio Management (APfM) model, the APMI – Agile Portfolio Management for insurers was designed and tested, showing how Agile and PfM international practices can be conciliated with current insurance industry-specific practices. Results revealed a high satisfaction level with the model implementation, indicating that the proposed model can foster a greater strategic alignment, increase the organization’s strategic focus, promote transversal alignment and visibility, and support the organization’s capacity coordination.

A Replication Study of Operations Management Experiments in Management Science
Authors: Davis Andrew M. , Flicker Blair , Hyndman Kyle , Katok Elena , Keppler Samantha , Leider Stephen , Long Xiaoyang , Tong Jordan D.
Published: July 2023

Over the last two decades, researchers in operations management have increasingly leveraged laboratory experiments to identify key behavioral insights. These experiments inform behavioral theories of operations management, impacting domains including inventory, supply chain management, queuing, forecasting, and sourcing. Yet, until now, the replicability of most behavioral insights from these laboratory experiments has been untested. We remedy this with the first large-scale replication study in operations management. With the input of the wider operations management community, we identify 10 prominent experimental operations management papers published in Management Science, which span a variety of domains, to be the focus of our replication effort. For each paper, we conduct a high-powered replication study of the main results across multiple locations using original materials (when available and suitable). In addition, our study tests replicability in multiple modalities (in-person and online) due to laboratory closures during the COVID-19 pandemic. Our replication study contributes new knowledge about the robustness of several key behavioral theories in operations management and contributes more broadly to efforts in the operations management field to improve research transparency and reliability.

Educação em design: reflexões a partir de abordagens feministas
Authors: Zacar Cláudia Regina Hasegawa , Jaco Hadassa Demenjeon , Pandini Julia Raniero
Published: July 2023

Neste texto temos como objetivo traçar algumas considerações sobre os processos de ensino e aprendizagem do design a partir de perspectivas feministas. Para tanto, apresentamos os resultados de uma revisão bibliográfica assistemática que abarcou trabalhos recentemente publicados em língua inglesa sobre o tema, incluindo ideias de pesquisadoras e docentes atuantes em cursos de design de diferentes áreas (produto, gráfico, moda, jogos). Destacamos duas abordagens alinhadas aos feminismos e que vêm sendo implementadas na educação em design: a interseccional, que permite embasar as discussões sobre como o design participa da constituição de identidades marcadas por gênero, raça, classe, sexualidade, etc., e como a articulação entre esses marcadores opera nas práticas educativas e projetuais; e a queer, que favorece um distanciamento em relação ao pensamento binário e aos modos hegemônicos de se pensar, ensinar, fazer e avaliar design.
Entre guardar e jogar fora: práticas de acúmulo e despojamento na cultura material
Authors: De França Ana Claudia Camila Veiga
Published: July 2023

Este artigo circunscreve o seguinte argumento: práticas de despojamento na cultura material constituem narrativas biográficas, de pessoas e de artefatos, estabelecendo e amparando rupturas e transformações em suas trajetórias. Para sustentar este argumento me apoio em teorias do consumo e da cultura material propostas por Barbosa (2004), Miller (2007, 2013) e Stallybrass (2008), e na exposição de práticas de acúmulo e despojamento descritas em investigações relacionadas à temática. Como resultado, destaco a possibilidade de compreender tais práticas como parte constitutiva de uma economia dos relacionamentos e das memórias, uma vez que podem apoiar perdas, corporificar memórias, atualizar biografias e relacionamentos e, inclusive, prolongar o uso de determinados artefatos. Para designers, considerar estas práticas, na esteira das discussões sobre a cultura material, oferece perspectivas mais amplas sobre o mundo material e suas implicações na vida das pessoas.
Design gráfico e imagem em movimento no Brasil: reflexões sobre o ensino de uma prática híbrida
Authors: Resing Daniela Souto , Geiger Noni
Published: July 2023

Este artigo apresenta parte de uma pesquisa em andamento que busca refletir sobre as atividades que integram design gráfico e imagem em movimento e os artefatos delas resultantes. Por meio de uma breve revisão bibliográfica, este estudo faz uma análise crítica e qualitativa que permite identificar fatos importantes no decorrer da história dessas práticas e sua consequente inserção nos cursos de graduação em design gráfico e afins. A partir de uma abordagem de perspectiva histórica e educacional voltada para o contexto brasileiro, é possível rever conceitos, teorias e referências para então propor futuros mais abertos aos designers que desejam aprender e/ou adotar a imagem em movimento em suas práticas.

O SERTÃO, A REGIÃO SEMIÁRIDA E SUAS REPRESENTAÇÕES TERRITORIAIS
Authors: Pereira Sidclay Cordeiro
Published: July 2023

As discussões sobre o semiárido brasileiro seguem vertentes construídas em contextos distintos, constitui-se como um território definido por critérios naturais de regionalização, bem como por delimitação legal. Porém, historicamente foi chamado de sertão, possuindo uma carga de simbologia, percepções e representações em espacialidades e temporalidades distintas. Neste sentido, faz-se aqui o uso da teoria das representações territoriais objetivando identificar e contextualizar quais são as representações dominantes sobre o semiárido. O recorte temporal compreende entre fins do século XVI até às primeiras décadas do século XXI. As fontes de informações foram autores e publicações de instituições que se debruçaram em estudar e entender o sertão e o semiárido. Como resultado, tem-se a identificação de quatro representações territoriais, a saber: o sertão como fronteira da colonização e dos espaços vazios, o sertão como uma região problema, o sertão como representação do passado e dos espaços das memórias e, por fim, o sertão como fronteira econômica na convivência com o semiárido. Espera-se que essas representações possam nortear futuras pesquisas.
ÁGUA, RECURSOS E SEGURANÇA HÍDRICA: UMA ANÁLISE A PARTIR DA HIDROGEOGRAFIA
Authors: Peixoto Filipe Da Silva
Published: July 2023

Seguindo uma postura epistemológica de visão ampla e histórica nas abordagens da geografia, a relação sociedade-natureza se estabelece como ponto comum nas variadas escolas de pensamento, suportando, ademais, na contemporaneidade, uma geografia socioambiental, sob a qual uma geografia das águas emerge. Assim, as reflexões aqui realizadas são de cunho teórico e prático, propondo uma maior significação geográfica das abordagens de pesquisa envolvendo a água, recursos hídricos e segurança hídrica, contribuindo para pressupostos teóricos-metodológicos em torno da Hidrogeografia. Para isso, duas aproximações foram inicialmente realizadas, esclarecendo as escalas global, regional e local de atuação do ciclo hidrológico, e pressupondo uma concepção epistemológica da água como recurso no território e este como categoria para revelar a forma pela qual a apropriação e usos desse recurso ocorrem, condições importantes para melhor delimitar a crise hídrica, a qual, produz o aumento dos conflitos decorrentes de atividades agro e mineroexportadoras, e revelam o Brasil como um dos principais exportadores de água virtual, enquanto uma parcela significativa, cerca de 35 milhões de brasileiros são oficialmente desprovidos de acesso água.
A AMAZÔNIA BRASILEIRA COMO A NOVA FRONTEIRA HIDROENERGÉTICA NO SÉCULO XXI: Degradação do trabalho represada na produção de energia elétrica
Authors: Alves José
Published: July 2023

O Brasil se insere na temporalidade da crise estrutural do capital nesse início de século XXI, vivenciando um processo intenso de reorganização do capitalismo nacional, denominado de Novo Desenvolvimentismo. Dentre as estratégias do Estado há a retomada do planejamento nos governos petistas, tanto nos mandatos de Luiz Inácio Lula da Silva, como de Dilma Rousseff, sendo o PAC o programa articulador, como no caso da política de infraestrutura energética. É nessa conjuntura que a Amazônia se reinsere como a nova fronteira hidroenergética a partir da transformação da mercantilização da natureza em territórios do hidronegócio-energético, como as UHEs de Jirau e Santo Antônio, no Complexo Hidrelétrico Madeira (RO). O problema norteador da investigação constituiu-se em evidenciar qual o papel da Amazônia na produção de energia hidrelétrica, bem como quais mediações e formas de controle do trabalho são mantidas entre capital, trabalho e Estado para a construção desses empreendimentos. Disso, objetiva-se analisar a superexploração do trabalho atrelada à construção da UHE de Jirau e os conflitos decorrentes das revoltas de trabalhadores nos anos de 2011 e 2012.
ANÁLISE COMPARATIVA ENTRE MÉTODOS ANALÓGICO E AUTOMATIZADO PARA A COMPARTIMENTAÇÃO GEOMORFOLÓGICA E OBTENÇÃO DE DADOS MORFOMÉTRICOS
Authors: Moroz-Caccia Gouveia Isabel Cristina , Ross Jurandyr Luciano Sanches
Published: July 2023

A pesquisa efetuou a comparação dos Índices de Dissecação do Relevo (IDR) do mapa geomorfológico do estado de São Paulo (ROSS e MOROZ, 1997) elaborado a partir de técnicas analógicas, e dados obtidos de forma automatizada com a aplicação do Índice de Concentração da Rugosidade – ICR (SAMPAIO e AUGUSTIN, 2014). 0bservou-se semelhanças visuais entre os resultados obtidos no ICR e IDR. Entretanto, ao efetuar a análise espacial em ambiente SIG (Sistema de Informações Geográficas), observou-se que as semelhanças entre limites de polígonos se restringem à 36,2%. A comparação indicou 37% de áreas coincidentes, 41% de classificações uma classe acima ou abaixo e, 22% de incongruências. Em relação à delimitação de subunidades morfoesculturais obteve-se correlações que variaram de 67,29 a 92,42%. Para a área toda, o percentual de semelhanças é de 89,15%. Os resultados apontam que o ICR apresenta grande potencial, entretanto, embora possa ser usado para compartimentações prévias de unidades espaciais homogêneas, deve ser complementado com levantamentos de campo e análises qualitativas uma vez que só a utilização de dados morfométricos pode implicar em resultados que não contemplam as complexidades do meio físico.
SERVIÇO DE REGULAÇÃO E MANUTENÇÃO DO CARBONO NA BIOMASSA ACIMA DO SOLO EM UM MANGUEZAL SEMIÁRIDO BRASILEIRO
Authors: Souza Yuri Gomes de , Souza Ana Caroline Damasceno , Saldanha Denise Santos , Costa Diógenes Félix da Silva
Published: July 2023

Esta pesquisa teve como objetivo identificar o serviço ecossistêmico de regulação e manutenção do carbono na biomassa acima do solo em um manguezal no litoral semiárido do Brasil (Piranhas-Açu/RN). Quanto aos procedimentos metodológicos, foram seguidos três pontos essenciais: 1) Vetorização da vegetação de mangue; 2) Estimativa da Biomassa Acima do Solo (AGB) e do Estoque de Carbono (EC); e 3) Identificação e espacialização da relevância do serviço ecossistêmico de regulação do carbono. O serviço ecossistêmico de captura de carbono foi classificado de acordo com a Classificação Internacional Comum de Serviços Ecossistêmicos (CICES). Em relação às estimativas de AGB, EC e CO2, essas corresponderam aos valores de 31,8, 15,1  e 55,4, respectivamente, resultando no total de 42,8 Gg de C estocado na AGB do mangue local. Ao utilizar a matriz de relevância, foi possível espacializar este serviço e observar que 37% dos dosséis possuem baixa capacidade de prestação deste serviço, enquanto que entre as classes de capacidade relevante e capacidade muito alta, o percentual representou 63% do total, suscitando em uma contribuição positiva deste ambiente na captura de CO2.
MAPEAMENTO ESPAÇO-TEMPORAL DA DUNA MÃE DA PLANICIE COSTEIRA DO CABO FRIO (RJ) DE 2005-2020
Authors: Pereira Matheus , Pereira Thiago
Published: July 2023

A planície costeira de Cabo Frio fica localizada em uma área onde coexistem elementos naturais (lagunas, vegetação de restinga, dunas estacionárias e transgressivas, etc.) com o sítio urbano do município. Ao investigar a dinâmica e comportamento da megaforma, constatou-se uma assimetria no seu deslocamento sobre a planície, com diferentes taxas de migração: 12,2m/ano em seu eixo central, e 7,3m/ano na face de avalanche. Em termos de área de abrangência a mesma apresentou uma perda de 9,4 ha de sua área, resultando assim em uma diminuição de 13,6%. Além da presença humana os ambientes costeiros também podem ser sensíveis a mudanças ambientais, como as mudanças climáticas e mudanças nos climas de ondas, podendo assim levar esses ambientes a um processo de transformação da paisagem, que possivelmente ocorre nesta área.
Os Guedes Alcoforado, moços fidalgos e “homens facinorosos”: dívidas, assassinato e conflito pela posse do engenho São João Batista (Itamaracá, século XVIII)
Authors: Morais Ana Lunara Da Silva
Published: July 2023

A família Guedes Alcoforado assentou-se em Pernambuco no início do século XVII, onde lutaram na Restauração contra os neerlandeses e passaram a integrar a nobreza da terra. Na década de 1730, João Guedes Alcoforado, por ter sido fiador de um contrato não pago à Fazenda Real, teve o seu engenho de açúcar, localizado em Itamaracá, penhorado para a quitação da dívida. A insatisfação da família com a penhora gerou uma contenda, culminando com o assassinato do almoxarife. A pesquisa evidencia uma complexa trama social acerca do endividamento e dos processos de penhora dos senhores de engenho, implicando nas estratégias de manutenção patrimonial de antigas estirpes. Para tanto, realizou-se a leitura e o cruzamento de diferentes fontes, algumas inéditas, existentes no ANTT, AHU, APEJE e IAHGP.
Sonhos proféticos de André Rebouças por uma Democracia Rural: o encontro do ‘maior inimigo dos Fazendeiros’ com as utopias cristãs de Tolstoi
Authors: Daibert Jr. Robert
Published: July 2023

O artigo tem como objetivo analisar a visão de propriedade rural elaborada por André Rebouças, em seu projeto de construção de uma Democracia Rural no Brasil e na África.  Nesse sentido, o texto está dividido em dois momentos em que o abolicionista propõe a transformação dos latifúndios em pequenas propriedades rurais. Na primeira parte, a proposta é estruturada a partir da leitura de seu livro Agricultura Nacional (1883) como referência, ao longo dos anos 1880, para sua luta em favor da extinção do monopólio territorial. Na segunda parte, o artigo investiga a apropriação das utopias cristãs de Tolstoi, a partir de 1888, pela militância intelectual de Rebouças em defesa da distribuição de terras e contra a miséria e a desigualdade social.
Maioria Absoluta (1964): crítica ao latifúndio pelas lentes de Leon Hirszman (1937-1987)
Authors: Marinho da Cunha Maíra Santana
Published: July 2023

A questão da propriedade privada se demonstra como central para o entendimento das sociedades modernas e capitalistas, na medida em que a base de sustentação deste sistema político, social e histórico – o capitalismo moderno, tem no valor particular a justificativa para a individualização da posse de terras. Nesse sentido, temos por objetivo apresentar neste artigo a forma como a crítica à propriedade foi feita pelo cineasta Leon Hirszman (1937-1987) no filme Maioria Absoluta (1962), durante um período da história do Brasil (1960-1964) marcado por intensas movimentações políticas de crítica ao modelo de desenvolvimento capitalista.
