Published: June 2024

Objective: The transportation sector is one of the supporting factors in creating emissions, moreover, population growth stimulates high mobility requirements. The purpose of this study is to compare the Semarang City and Yogyakarta governments to realize sustainable mobility in their cities.
 
Theoretical Framework: This research uses two theoretical perspectives from Jeon (2013) and Karjalainen & Juhola (2019). Where Jeon's theory is more focused on environmental sustainability and cultural preservation, while Karjalainen & Juhola's theory is focused on economic effectiveness. These two theories are used because they complement each other, especially to analyze the government's strategy in realizing green transportation and developing sustainable transportation mobility for society.
 
Method: The methodology adopted for this research is a qualitative method with a case study approach, where the data collection techniques used include in-depth interviews and documentation. Interviews were conducted with Bappeda and related agencies, while documentation was taken from organizational performance reports and mass media. In addition, in processing and presenting research data using Nvivo tools.
 
Results and Discussion: This study found that the public transport in Semarang City is more prepared to realize sustainable transportation compared with Yogyakarta. The Semarang City Government constructed a public transport system that is integrated, effective, accessible, and inclusive which is the reason for the community to move to public transport rather than private vehicles. Meanwhile, the public transport in Yogyakarta lacks facilities that are inclusive, accessibility, and proper infrastructure, forcing the community to find other options for their mobility mode such as private vehicles and online transport services.
 
Originality/Value: This study is analyzing the sustainable mobility concept from government approach with collaborating the socio-environment perspective and economic consideration, which those are present the government context to plans, budgeting and implement it. The theory collaboration of this study will be a novelty, that can contribute to creating a new perspective on sustainability context of government study approach.

Authors: Shihab Thaer Jadou , Dheebi Mohammed
Published: June 2024

Objectives: This study aimed to identify the impact of internal control, represented by the independence of internal control, professional competence of internal auditors, and internal control activities, in the Iraqi ministries on the preparation and implementation of the general budget.
 
Methods: The study methodology relied on the descriptive and analytical approach. The researcher used the questionnaire as the main tool for this study. The study population consists of employees of various Iraqi ministries.
 
Results: The results showed a high degree of independence of internal control, indicating that internal control implementation policies are being executed to avoid conflict of interest situations. The internal control staff also has the authority to access all records and files without restrictions. Additionally, the results highlighted the significant role of professional competence of internal auditors in implementing the general budget. However, the internal control activities were only moderately effective in implementing the general budget. This suggests that most of the study sample indicated that internal control does not submit periodic reports to senior management and the board regarding management reports on the performance of its plan.
 
Conclusion: The study recommended developing a code of professional conduct to help enhance the values of integrity and transparency among auditors of internal control units in Iraqi ministries. This is aimed at improving the effectiveness of internal control activities and ensuring better implementation of the general budget.

Cuba's Energy Future: Options Based on Renewables and Non-Carbon-Based Sources
Authors: Crawford Colin
Published: June 2024

My intention is to research and write on article on Cuba's energy future. Specifically, I plan to consider the options for a sustainable energy future using renewable energy sources and not carbon-dependent sources. This analysis will require both an examination of the island's historical energy challenges as well as consideration of the options for developing a sustainable energy infrastructure with international governmental (e.g. UN, World Bank etc.) and regional governmental (e.g. EU) support- an analysis that will also require consideration of the island nation's socialist political system and its willingness to engage internationally. The topic is one, clearly, with implications for climate change and environmental protection, as well as one that raises questions of environmental justice (since energy availability has not, even since the Revolution, been equally enjoyed by all.)
Transition-Denial and Structural Adjustment: Causation and Culpability in the Cuban Economy
Authors: Gabilondo José
Published: June 2024

In 2020, Cuba implemented the Tarea Ordenamiento (Tarea), the most significant economic reform since the construction of the socialist economy after the Revolution. Signaling an eclectic brand of Cuban socialism, the Tarea clears away three decades of tried and failed economic doctrines, drawing a new fiscal border around state enterprises, nodding to market realities, and preparing the island for greater insertion into the world economy. While the political economy of post-Castro Cuba has changed in this way, the United States continues to subject the island to an unprecedented program of unilateral sanctions, universally condemned as a breach of human rights, international law, sovereignty, and rationality. Given the historic limitations of Cuba’s economic policies and the noxious effects of U.S. policy, how do we assign proximate cause for the mixed results to date of the Tarea?

Save Your Rights: How Florida and Other States Have Targeted Voting Access Following the 2020 Election
Authors: Varona Francisco
Published: June 2024

Following the 2020 general election, Florida’s Republican led legislature introduced Senate Bill 90 (“S.B. 90”), which seeks to put many restrictions on various aspects of the voting process. S.B. 90 limits ballot drop-off boxes, restricts mail-in voting, proscribes “line-warming,” increases registration difficulty, and expands identification requirements. Despite lauding Florida’s election as a gold standard for the rest of the country, Governor Ron DeSantis approved this bill in May of 2021, explaining that Florida should not become complacent despite its success. The Republican Governor approved this law against the backdrop of record voter turnout for Black and Latino voters and record mail-in voting by Democrats. Florida Rising Together, a grassroots organization working alongside other similar organizations, has filed suit against the State of Florida. Florida Rising Together’s suit alleges that this law intends to discriminate against Black, Latino, and elderly Florida voters by suppressing their vote. Florida Rising Together sought to introduce three professors from University of Florida as expert witnesses in their case against Florida. In response, the university—a public institution and organ of the Florida State government—barred all three professors from serving as expert witnesses for a party adverse to the State’s interests. While unprecedented, experts assert that the university’s conduct implicates violations of the professors’ First Amendment rights, despite any likelihood of a conflict of interest existing between them and their employer. By using the Pickering balancing test, the United States District Court for the Northern District of Florida should find that any conflict of interest the professors’ expert testimony may create in their relationship as state employees is far outweighed by the professors’ interest, as citizens, to comment upon matters of public concern—whether Florida’s newly implemented law violates the Fifteenth Amendment of the Constitution and the Voting Rights Act. Furthermore, Florida Rising Together (“Florida Rising”) should bring a Section 1985 claim against University of Florida officials for intimidating witnesses in a civil rights case.

Objetivo: Relatar um caso de associação cardíaca congênita complexa. Detalhamento de caso: Recém-nascido pré-termo tardio, adequado para idade gestacional, masculino, cujos exames pré-natal sugeriam trissomia do cromossomo 21. Ecocardiograma fetal com diagnóstico sugestivo de coarctação de aorta associada ao defeito do septo atrioventricular (DSAV) total. Parto programado em maternidade de alto risco. Ecocardiograma pós-nascimento evidenciou interrupção do arco aórtico (IAA) + DSAV total. Como defeito congênito de canal arterial dependente, foi realizada infusão de prostaglandina e as equipes cirúrgica e cardiologia pediátrica acionadas. Realizada angiotomografia computadorizada de coração e vasos da base para melhor estudo anatômico e programação da intervenção. Aos 21 dias, submetido à implante de “stent” no canal arterial, via hemodinâmica, bem-sucedido e sem intercorrências. No 7º dia pós-procedimento, estável hemodinamicamente, com dispositivo posicionado no canal, bom fluxo e função cardíaca preservada. Ajustadas medicações anti congestivas, seguimento ambulatorial com cardiologia pediátrica, aguarda correção cirúrgica total do defeito. Considerações finais: A IAA é uma anomalia de elevada morbimortalidade. A confirmação diagnóstica e a conduta efetiva permitiram sobrevida diante da cardiopatia de hipofluxo sistêmico, dependente de canal arterial. A não intervenção precoce é etiologia para insuficiência cardíaca grave, choque cardiogênico e óbito. O diagnóstico pré-natal, em casos complexos, possibilita a preparação da equipe assistencial no diagnóstico e condução dos pacientes.

Vertical Ionization Energies, Generalized Kohn-Sham Orbital Energies, and the Curious Case of the Copper Oxide Anions
Authors: Shahi Chandra , Maniar Rohan , Ning Jinliang , Csonka Gabor I. , Perdew John P. , Ruzsinszky Adrienn
Published: June 2024

Are the vertical ionization energies from a bound electronic system, initially in its ground state, equal to minus the corresponding exact Kohn-Sham orbital energies of density functional theory (DFT)? This is known to be true for the first or lowest vertical ionization energy. We show that the correction from time-dependent DFT arises from the continuum and need not vanish. Recent work compared the experimental photoemission thresholds of the molecules Cu2O−, CuO−, CuO− 2 , and CuO3− with minus the corresponding orbital energies from a generalized gradient approximation (GGA) and its global and range-separated hybrids with exact exchange, finding striking differences which were attributed to self-interaction error, strong correlation, or both. Here we extend that work to include the local spin density approximation (LSDA), its Perdew-Zunger self-interaction correction with Fermi-L¨owdin localized orbitals (LSDASIC), a quasi-self-consistent locally scaled-down version of LSDA-SIC (QLSIC), and the Quantum Theory Project QTP02 range-separated hybrid functional, all but LSDA implemented in a generalized Kohn-Sham approach. QTP02 impressively yields a near equality for many sp-bonded molecules. But, for the copper oxide anions studied here, none of the tested methods reproduces the experimental photoemission thresholds.

Dynamic polymers of tubulin, known as microtubules, are among the most important targets for anti-cancer chemo-therapy. Although several inhibitors of tubulin polymerization are clinically successful, the resistance of cancers to existing drugs urges for the development of novel tubulin-binding substances that can inhibit microtubule dynamics. Here we explored new 1,5-disubstituted pyrrolidin-2-ones 1, 2 and 5-aryl-3,3a,4,5-tetrahydropyrrolo[1,2-a]quinoline-1(2H)-ones 3 as potential binders of the colchicine site of tubulin. We evaluated their effects on microtubules dynamics in vitro and on the proliferation of cultured cancer cell lines. Guided by molecular modeling of the interactions between tubulin and the most active of identified compounds, we designed, synthesized, and tested the 3-hydroxyphenyl-substituted compound 3c, which decreased microtubule growth rate in vitro and arrested cancer cells division in the low micromolar range (IC50 = 6.6 μM). This finding demonstrates that 5-aryltetrahydropyrrolo[1,2-a]quinoline-1(2H)-one is a promising scaffold for the development of novel efficient tubulin polymerization inhibitors.
Exploiting Decarbonylation and Dehydrogenation of Forma-mides for the Synthesis of Ureas, Polyureas, and Poly(urea-urethanes)
Authors: Luk James , Goodfellow Alister , More Nachiket , Buehl Michael , Kumar Amit
Published: June 2024

Urea derivatives, polyureas, and poly(urea-urethanes) are materials of great interest. However, their current methods of syn-thesis involve toxic feedstock - isocyanate and phosgene gas. There is a significant interest in developing alternative meth-odologies for their synthesis from safer feedstock. We report here new methods for the synthesis of urea derivatives, polyure-as, and polyurea(urethane) using a ruthenium pincer catalyst. In this approach, urea derivatives and polyureas are synthesized from the self-coupling of formamides and diformamides, respectively, whereas polyurea(urethanes) are synthesized from the coupling of diformamides and diols. CO and H2 gases are eliminated in all these processes. Decarbonylation of formamides using such organometallic catalysts has not been reported before and therefore mechanistic insights have been provided using experiments and DFT computation to shed light on pathways of these processes.

Published: June 2024

Plant-microbe interactions play a crucial role in ecosystem dynamics and agricultural productivity. Metabolomics has emerged as a vital tool for deciphering the complex chemical exchanges that govern these interactions, providing a comprehensive insight into metabolic processes. This review explores a variety of metabolomics techniques used to study plant-microbe interactions, including mass spectrometry, nuclear magnetic resonance spectroscopy, and imaging methods. The review also discusses the application of advanced bioinformatics tools, databases, and the increasing influence of artificial intelligence and machine learning in metabolomics data analysis. The integration of metabolomics with other omics disciplines, such as transcriptomics, proteomics, and metagenomics, offers a comprehensive understanding of the molecular mechanisms underlying these interactions. Additionally, the review highlights the complementary role of fluxomics in revealing the dynamic aspects of metabolic networks. Despite challenges in data analysis and interpretation, metabolomics has significantly enhanced our understanding of the diverse roles of metabolites in shaping plant-microbe interactions. As metabolomics technologies continue to evolve and integrate with other omics approaches, we anticipate groundbreaking discoveries that will revolutionize sustainable agriculture and biotechnology.
Molecular Simulations of Thermal Transport across Iron Oxide-Hydrocarbon Interfaces
Authors: Carman Fionn , Ewen James P. , Bresme Fernando , Wu Billy , Dini Daniele
Published: June 2024

Immersion cooling technology offers more effective thermal management of electric vehicle (EV) batteries. The rational design of dielectric fluids for this application requires a molecular-level understanding of the heat flow across the battery casing/dielectric fluid interface. Here, we use non-equilibrium molecular dynamics (NEMD) simulations to quantify the interfacial thermal resistance (ITR) between hematite and poly-𝛼-olefin (PAO), which are representative of the outer surface of the steel battery casing and hydrocarbon dielectric fluid, respectively. After identifying the most suitable force fields to model the thermal properties of the individual components, we then compared different solid-liquid interaction potentials for the calculation of the ITR. These potentials lead to a wide range of ITR values (4-21 K m^2 / GW), with stronger solid-liquid interactions leading to lower ITR. The increase in ITR is correlated with an increase in density of the fluid layer closest to the surface. Since ITR has not been experimentally measured for the hematite/PAO interface, we validate the solid-liquid interaction potential using the work of adhesion calculated using the dry-surface method. The work of adhesion calculations from the simulations were compared to those derived from experimental contact angle measurements for PAO on steel. We find that all of the solid-liquid potentials overestimate the experimental work of adhesion. The experiments and simulations can only be reconciled by further reducing the strength of the interfacial interactions. This suggests some screening of the solid-liquid interactions, which may be due to the presence of an interfacial water layer between PAO and steel in the contact angle experiments. Using the solid-liquid interaction potential that reproduces the experimental work of adhesion, we obtain a higher ITR (33 K m^2 / GW), suggesting inefficient thermal transport. The results of this study demonstrate the potential for NEMD simulations to improve understanding of the nanoscale thermal transport across industrially-important interfaces. This study represents an important step towards the rational design of more effective fluids for immersion cooling systems for electric vehicle batteries and other applications where thermal management is of high importance.
Thio-Cycloolefin Ligand Enabled Distal Methylation in the Catellani-Type Reaction via a Six-Membered Palladacycle
Authors: Wang Feng-Yuan , Tan Yi-Fan , Jiao Lei
Published: June 2024

The Catellani reaction, also known as the Pd/norbornene catalysis, is a potent method for synthesizing multisubstituted arenes through the ortho-functionalization/ipso-termination process of haloarenes. This chemistry relies heavily on the formation of a five-membered palladacycle, restricting the ortho-functionalization to the aryl ring bearing the ipso-halogen. In this study, we present an innovative strategy to circumvent this limitation, expanding the synthetic capabilities of the Catellani-type reaction. By employing the Pd/olefin ligand cooperative catalysis developed within our research group, we successfully executed a non-classical Catellani-type reaction on a 6,5-fused heteroaromatic system via a six-membered palladacycle intermediate. The use of a functionalized thio-cycloolefin ligand with an amide group as the functional moiety and a connecting unit bearing a geminal-dimethyl group enabled distal C−H methylation at the 4-positions of 3-iodoindole, 7-azaindole, and indolizine rings, providing a novel pathway for the synthesis of methylated analogs of pharmaceutical compounds based on these scaffolds. This study highlights the potential of Pd/olefin ligand catalysis in unveiling new reactivity for advancing non-classical Catellani-type reactions.

Após mais de um ano da eclosão da pandemia da Covid-19, vemos os efeitos colaterais da crise sanitária, econômica, social e política, que além de promover a morte de várias milhares de pessoas, intensificou as desigualdades de gênero, raça e classe. O artigo investiga alguns impactos da pandemia no trabalho de reprodução social da vida, realizado majoritariamente por mulheres no Brasil. O artigo, analisando as imbricações de classe, raça e gênero, enfatiza também os impactos da pandemia na vida das trabalhadoras domésticas no país.
Racismo estrutural e violência institucional no campo da política
Authors: Pacheco Eriane , Mara de Oliveira Machado Loiva , Thais Guterres Dias Miriam
Published: June 2024

O artigo visa refletir sobre as expressões do racismo estrutural na realidade brasileira, considerando o lócus do exercício da política, no âmbito do legislativo municipal, que para além disputa de projetos societários, vem evidenciando a violência sofrida por corpos negros/as e LGBTQIA+ que conflitam com o perfil inscrito no sistema de privilégios na forma de sociabilidade capitalista. Reconhecemos, a partir de uma abordagem crítica, inscrita no materialismo histórico dialético, a interseccionalidade na abordagem teórico-prática entre raça, classe e gênero. Sob essa perspectiva partimos da realidade de violência vivida por mulheres negras no Brasil, considerando seus agravos em tempos de pandemia da Covid-19. Na sequência buscamos elucidar o significado do racismo estrutural e da violência racial e suas repercussões no campo da política. Por fim, problematizamos algumas estratégias de enfrentamento a violência racial na política, com vistas a incidir numa pauta de lutas pela garantia de direitos humanos em tempos de barbárie.
As mulheres no espaço de luta pela saúde bucal da pessoa com deficiência no Brasil
Authors: Santos Carla Maria Lim , Lima Chaves Sônia Cristina , Freire de Souza Lima Ana Maria , Figueredo de Santana Sisse
Published: June 2024

Este estudo sócio-histórico, com abordagem na sociologia reflexiva de Pierre Bourdieu, buscou compreender as contribuições de mulheres no espaço de luta pela atenção à saúde bucal da pessoa com deficiência, no Brasil, entre 1970 e 2012. Trajetórias, posições, disposições e tomadas de posição foram identificadas nas 14 entrevistadas. O estudo revelou que houve influência de mulheres na articulação com o Estado, para incorporação das categorias de pensamento dos movimentos sociais. Essa atuação foi mais evidente para os espaços associativos da PcD, ainda que o campo odontológico tenha pioneirismo feminino no campo burocrático. Dentro do universo de possíveis, ter maior capital burocrático, habitus político, ser de religião católica e estar no campo burocrático na época de formulação da Política Nacional de Saúde Bucal foram características das agentes no campo do poder.

Authors: Silva Adorno Emillyane Cristine , Penazzo Tavares Alex , Vechi Fernando
Published: June 2024

O artigo consistiu em analisar a constitucionalidade da legislação penal brasileira sobre o aborto. Foi investigado o tratamento histórico sobre os direitos sexuais e reprodutivos das mulheres, identificando aquelas mais suscetíveis aos efeitos da criminalização do aborto, tratando-se de pesquisa qualitativa, com método de procedimento bibliográfico e comparativo em que foi realizada análise indireta dos dados. Foi possível discutir a constitucionalidade do tipo penal, comparando com posicionamentos de Tribunais Constitucionais de outros países. Por fim, identificamos que as mulheres mais suscetíveis aos impactos da criminalização do aborto no país são adultas jovens, com baixa renda e escolaridade, pretas, pardas e indígenas, o que confirma uma seletividade criminal.
O Discurso Jurídico para Reconhecimento de Nome e Gênero: breves Considerações Acerca do Provimento nº 73/2018 do Conselho Nacional de Justiça
Authors: Amorim Bulzico Battaglin Bettina Augusta
Published: June 2024

O presente artigo pretende apresentar uma análise crítica ao discurso jurídico que envolve a regulamentação do procedimento administrativo de alteração de nome e gênero do sujeito transgênero junto ao cartório de Registro Civil de Pessoas Naturais (RCPN).  Ao invés de regulamentar o tema de forma a assegurar a dignidade dos titulares dos direitos em questão, o Conselho Nacional de Justiça (CNJ) optou por manter termos e métodos decorrentes do discurso heteronormativo dominante, que reforçam a discriminação sofrida.
José Martí e Paulo Freire: a inserção nas insurgências pedagógicas da América Latina
Authors: Leite Maria do Carmo Luiz Caldas
Published: June 2024

Com o objetivo de aproximar os pensamentos de José Martí e de Paulo Freire, destacam-se as contribuições ao ideário educativo da América Latina. São arrolados dois aspectos: a) a inserção das obras freiriana e martiana à história das insurgências, que radica na indignação diante das injustiças; b) a autoctonia que reafirma a cultura ajustada à realidade latino-americana e não importada da Europa e da América Anglo-Saxônica. Dentro da profusão textual de Martí e de Freire, a escolha voltou-se à construção de uma pesquisa bibliográfica. Como conclusão, apresenta-se a relevância destes legados no bojo da radicalidade pedagógica, salientando categorias comuns, entre elas a liberdade para refletir como variante da vinculação da teoria com a prática e da escola com a vida.
O lugar da assessoria jurídica popular como práxis de educação popular freireana: a atuação do NAJUP Josiane Evangelista no Acampamento Leonir Orbhak (MST-GO)
Authors: Diehl Diego Augusto
Published: June 2024

O artigo retrata o histórico de lutas de trabalhadores/as rurais sem terra que, após diversos despejos e da criminalização de alguns de seus militantes, constituíram o acampamento Leonir Orbhak, no município de Santa Helena de Goiás-GO. Com o objetivo de analisar a relação entre a AJP e a comunidade organizada no MST, o artigo destaca o papel pedagógico assumido por apoiadores e pelo NAJUP Josiane Evangelista na construção coletiva da luta pela terra, na mobilização dos direitos humanos enquanto temas geradores, na construção de ferramentas de educação popular para melhor conhecer os opressores e suas estratégias, além de promover uma tradução da linguagem jurídica para a linguagem popular de questões jurídicas complexas que envolvem a luta pela terra naquele contexto.

As transitividades da consciência estudantil em uma Faculdade de Direito: a experiência crítica do Grupo Paulo Freire na UFPR
Authors: Pereira Natalia Demes Bezerra Tavares , Pazello Ricardo
Published: June 2024

Este ensaio tem por objetivo apresentar a experiência do Grupo Paulo Freire, criado na Faculdade de Direito da Universidade Federal do Paraná, durante os anos 2000. A partir de fontes primárias – como mensagens eletrônicas, relatorias de debates, sistematização de documentos de intervenção estudantil e textos publicados – o relato busca recompor momentos-chave do grupo, relacionando-o a seu contexto, a sua composição e a seus intentos de atuação prática. Para além do relato, o artigo pretende também realizar uma avaliação, à luz de categorias freireanas, das contribuições que a experiência trouxe para se pensar a educação jurídica. A partir de noções como as de consciência transitiva, criticidade, dialogicidade e práxis, pode-se perceber os movimentos de um coletivo de estudantes universitários em um curso de direito rumo a uma educação problematizadora, mas também o potencial da obra de Paulo Freire para a seara jurídica.

Com quem? junto a quem? contra o quê? convergências, diferenças, divergências, oposições (uma contribuição aos circuitos de escritos e diálogo ao redor dos “100 anos de Paulo Freire”)
Authors: Rodrigues Brandão Carlos
Published: June 2024

O que importa neste breve escrito são as convergências, as diferenças, as divergências e as oposições em e entre vocações da educação em nossa atualidade. Este será o momento de relembrar que Paulo Freire escreveu Pedagogia do Oprimido como um livro assertivamente “contra”. Enfim, não se trata de apenas buscar melhorar o existente no interior do cultural campo da educação. Trata-se de buscar em e entre territórios em disputa, o lugar de uma nova hegemonia. E, em sua busca do “inédito viável”, a procura de seu horizonte possível. Trata-se de propor outras contra-vocações; estabelecer e afirmar outras pedagogias; ocupar e preservar a territórios libertados para uma educação emancipadora através de outras escolas e outras diferentes instâncias do ensinar-e-aprender.
