Límites de la historia social clásica de la pobreza y la asistencia en España
Authors: Carasa Pedro
Published: January 2025

No contexto das quatro etapas da historiografia espanhola sobre pobreza e assistência, analisam-se os objectivos que nortearam cada geração de historiadores. Estes estiveram sempre vinculados aos sistemas gerais de cada momento histórico e dependentes da ideologia de cada período historiográfico, desde o providencialismo, até ao pós-modernismo, passando pelo liberalismo e o materialismo histórico. As suas limitações mais gritantes foram impostas pela racionalidade clássica-patriarcal aplicada à economia e à sociedade, por se centrar nos sistemas e não nas pessoas, por se esgotar no método dialéctico e por se apoiar nos sujeitos abstractos, colectivos e institucionais dos privilegiados, a Coroa, o Estado ou a classe social. O resultado foi o fraco protagonismo do sujeito consciente e a desumanização da história social.
Los pasaportes internos como fuente para el estudio de la emigración gallega al norte de Portugal (1700-1850)
Authors: J. Fernández Cortizo Camilo
Published: January 2025

A investigação sobre a emigração galega para o Norte de Portugal tem conquistado, desde os anos 1990, o interesse de um crescente, embora ainda reduzido, número de historiadores portugueses e galegos; os factores que explicam este novo impulso são certamente vários, um dos quais, de inegável influência, foi a consulta de um corpo mais alargado e diversificado de fontes documentais de arquivos, tanto portugueses como galegos, de resto nada ou muito pouco exploradas até à data. Entre estas fontes encontramos os passaportes internos que, pese a sua implantação temporal tardia (1760), a sua conservação descontínua até à supressão (1863) e a falta de homogeneidade dos seus registos, são sem dúvida o fundo documental com a informação mais plural sobre emigrantes galegos, permitindo conhecer aspectos tão variados como a localidade de origem e de destino, duração da viagem ou de permanência, actividade profissional, sexo, idade, estado, etc. Assim, o seu contributo, em complementaridade com o de outras fontes de natureza diversa (arquivos paroquiais, registos hospitalares, livros de contas das alfândegas, etc.), tem-se revelado imprescindível na mais recente investigação sobre a emigração galega para Portugal e na ampliação espacial da área de estudo, agora já estendida desde o litoral minhoto a Trás-os-Montes e Alto Douro.
Percursos de vida. As potencialidades da micro-história e das pesquisas biográficas
Authors: Durães Margarida
Published: January 2025

Este texto tem como objectivo conhecer alguns aspectos que qualificam os comportamentos dos negociantes inseridos nas comunidades camponesas. Transformando-se em intermediários privilegiados, entre as economias do mundo rural e do mundo urbano, os negociantes desenvolveram estratégias comerciais que possibilitaram a utilização, em seu beneficio, da dependência dos camponeses na venda dos excedentes agrícolas. Partindo de um estudo de caso e utilizando os procedimentos da micro-história, estudou-se um espólio documental privado - produzido por um jovem negociante estabelecido, aos 22 anos de idade, na freguesia de Paderne, concelho de Melgaço, junto da fronteira luso-galaica - de onde foram retiradas informações que cruzadas com os conteúdos de outras fontes - registos paroquiais e, sobretudo, os livros de notas dos tabeliães e os recenseamentos eleitorais - permitiram conhecer o seu percurso de vida bem como o conjunto de estratégias que levou a cabo para intensificar a actividade comercial e obter o reconhecimento dos seus pares e da sociedade onde se introduziu. O estudo desenvolve uma narrativa do "individual" que analisa um percurso de vida. Porém, a inserção das estratégias, pessoais e familiares deste negociante, no contexto socioeconómico e político da região, possibilitarão o conhecimento do modelo cultural dos homens de negócio.
Rumos da Historiografia Portuguesa
Authors: Marques A. H. de Oliveira
Published: January 2025

Rumos da Historiografia Portuguesa procura reflectir sobre as tarefas urgentes e necessárias para a sua actualização. O futuro da História passará por esquecer mais as grandes estruturas, os grandes movimentos estratégicos e as explicações "profundas" (que raras vezes se encontram como factores motivantes e transformadores) e atender antes a aspectos práticos e quotidianos que podem e devem ser analisados com o auxílio das novas descobertas de tipo científico e técnico.
Percepções em torno da história do tabelionado medieval português
Authors: Gomes Saul António
Published: January 2025

Neste artigo, depois de se expor a bibliografia mais recente sobre a história do tabelionado português medievo, aborda-se o problema da sua implantação no País, entre os séculos XII e XIII, após o que se referencia o seu papel social no século XIV segundo as críticas que, cerca de 1340, D. Álvaro Pais, o conhecido autor do De statu et planctu Ecclesie e bispo de Silves, fez incidir sobre o seu comportamento, em geral, para, por fim, se passar a avaliar a relevância assumida por este corpo jurídico e intelectual no domínio da garantia dos direitos judiciais dos povos, conforme se pode percepcionar a partir da análise do discurso dos procuradores concelhios nas assembleias parlamentares de Quatrocentos.
António de Conti, Favori de D. Afonso VI
Authors: Guiraud Michèle
Published: January 2025

Os escassos anos do reino daquele que o Conde de Castelo Melhor chamava o "Vitorioso" apenas ocuparam um lugar menor nos livros de história. Para a maioria dos historiadores, o reino de Dom Afonso VI brilhou menos pelas vitórias militares alcançadas sobre o inimigo ou pelas alterações introduzidas pelo primeiro-ministro do que pelos excessos de um rei considerado incapaz. Por essa razão, procurámos conferir a este rei o esplendor que lhe é devido. Neste contexto, e com o intuito de conseguirmos uma compreensão mais justa e mais exacta da época em questão, abordamos a personagem de António de Conti: como foi apresentado à corte e o papel que desempenhou junto de Dom Afonso VI.

Concerns surrounding the frequent exposure to QAC
Authors: Milner Delilah
Published: January 2025

Quaternary ammonium compounds (QACs) are a class of compounds typically used as antimicrobials, preservatives, conditioners, and disinfectants. They appear in consumer products such as hair conditioners, mouthwashes, nasal sprays, hand sanitizers, and disinfectant wipes and sprays. 2 However, there are some concerns associated with QACs. Evidence suggests that they might be less effective compared to alternative cleaners. Additionally, there have been concerns about the continued use of QACs as they are present in the environment and can accumulate in humans. QAC cleaners vary in toxicity and have been connected to multiple issues such as decreased mitochondrial function, cholesterol homeostasis disruption, and decreased fertility.

Published: January 2025

O projeto “Flores para Todos” realizado pela Equipe PhenoGlad no Brasil, tem como objetivo difundir a floricultura como uma alternativa de renda e diversificação para as pequenas propriedades rurais. Uma das culturas introduzidas foi a do gladíolo, que se destacou como uma excelente opção para os pequenos produtores. Nesse contexto, o trabalho concentrou-se em oferecer acompanhamento e assessoria sobre plantio e manejo de gladíolos, na escola municipal de campo Attílio Benedetti, localizada na zona rural do município de Vacaria/RS. Os estudantes foram protagonistas ao realizarem o plantio de 100 bulbos de gladíolos em um canteiro de 2,0m x 6,0m. O experimento abrangeu por quatro cultivares distintas variando em cores e ciclos de desenvolvimento. Ao longo do projeto, foram realizadas visitas semanais, desde o plantio até a colheita das hastes de gladíolo, proporcionando aos estudantes o aprendizado das técnicas de cultivo. Como parte dos resultados alcançados, em 6 de junho, foi realizado um “Dia de Campo”. Por meio dessa iniciativa, o projeto de extensão possibilitou uma notável interação entre a universidade e a comunidade escolar. O que enaltece a indissociabilidade entre o ensino, a pesquisa e a extensão, promovendo o cultivo de novas alternativas para os pequenos produtores da região.

Published: January 2025

No projeto de extensão “Aspectos emocionais da amamentação: abordagem psicoeducativa das mães e acompanhantes usuários do BLH do HC-UFU”, as extensionistas têm a oportunidade de ofertar escuta às mães e aos familiares que chegam ao Banco de Leite Humano (BLH) do Hospital de Clínicas da Universidade Federal de Uberlândia em busca de orientações acerca da amamentação. Tendo em vista o desenvolvimento do trabalho realizado no projeto, o presente relato de experiência tem como objetivo apresentar as atividades, os resultados e os aprendizados obtidos pelas extensionistas, além de dispor de uma reflexão acerca da riqueza de conhecimentos que sustentam e extrapolam as práticas da extensão. Os resultados apontam em direção ao uso refinado de recursos de escuta, em uma prática extensiva, para o estabelecimento de uma escuta sensível – em especial, no acolhimento de diferentes afetos que emergem em um campo do contexto hospitalar, que perpassam pelo imaginário social da maternidade –, além das contribuições para a formação acadêmica das discentes. Conclui-se que a ação se provou profícua no sentido de promover trocas entre a comunidade e a equipe técnica do local, oferecendo às extensionistas a oportunidade de enriquecerem os próprios conhecimentos, os recursos técnicos e a postura profissional e ética.

Authors: Silva Rodrigo Rosalis da , Nicola Vítor Rafael
Published: January 2025

A análise de conjuntos de dados voltada para obtenção de informações estratégicas relevantes, de modo que melhorem a qualidade das decisões tomadas em grandes empresas, tornou-se um campo conhecido, assim como os conhecimentos que compõem o tema, como estatística, programação, softwares de planilhas eletrônicas e tratamento de banco de dados. Mas, a compreensão básica sobre esse processo pode proporcionar benefícios para a comunidade e negócios locais. Assim, o projeto apresentado neste artigo busca aproximar o tema da comunidade, adaptando-o para situações cotidianas de alunos do ensino médio regular, técnico e de turmas de Educação de Jovens e Adultos, para que esses participantes passem a compreender que um olhar analítico ajuda a identificar os dados existentes em uma situação problema, criar uma organização e construir relações entre aquelas coleções de valores, produzindo informações que permitam fundamentar a capacidade decisória. A abordagem foi feita por meio de oficinas práticas em laboratório de informática, contendo temas como orçamento familiar, análise de dados de cadastro de clientes e transporte. O resultado foi um crescimento pessoal e profissional tanto para os alunos participantes quanto para os discentes que ministraram a prática extensionista.

Prática de leitura literária
Authors: Veronez Manuel , Viana Ana Luiza
Published: January 2025

O projeto de extensão “Prática de leitura literária: aprendendo com a poesia” foi criado com o objetivo de promover um incentivo à leitura de poesias pelo simples ato de apreciar a fruição estética. A prática de leitura literária, principalmente de poemas, tem sido desconsiderada pela sociedade atual. Os jovens têm dado preferências às redes sociais, que entregam conteúdos rasos, simplistas e de curta duração, mas, que tem um grande poder de prender a atenção. Dessa forma, as habilidades adquiridas com o hábito da leitura, como a atenção, o pensamento crítico e a criatividade, têm se perdido. Dessa forma, o projeto se desenvolveu a partir dessa análise de sociedade e, a fim de ampliar os repertórios culturais e exercitar o hábito da leitura, em cada encontro desenvolvido, foi enfatizada a importância dos(as) autores(as) para o acervo cultural brasileiro, refletindo sobre sua trajetória de vida e suas obras escritas. A partir disso, o público tinha espaço para expor/falar suas ideias e reflexões que vieram a mente ao longo da leitura das obras e, assim, formava-se um ambiente seguro e criativo para a troca de ideias e vivências. Tivemos poucos adeptos, mas buscaremos encontrar melhores soluções para os próximos projetos.
Colour in Iberian Iron Age architectural sculpture: the case of Cerro de la Merced
Authors: Quesada Sanz Fernando , Robles Moreno Jesús , Parra Crego Enrique , Sánchez Marqués María Isabel
Published: January 2025

Recently, analytical research has confirmed the use of pigments in Iberian Iron Age freestanding sculpture. However, hard evidence of polychromy on the many preserved remains of architectural sculpture is still scarce. We focus on the case of a large block decorated with reliefs, probably dated to the end of the 5th or the beginning of the 4th century BCE, recently found at Cerro de la Merced (Cabra, Córdoba). Employing optical and electron microscopy analyses, FTIR spectroscopy, and GC-MS, it has been possible to confirm the existence of traces of red and white colour covering the entire surface, analyse the composition of the pigments employed, and to reconstruct the colour patterns of the different elements of the relief. Our aim is to deepen our understanding of the use of colour in Iberian architecture and to shed light on the colours employed, the techniques used to apply them and their arrangement patterns.

Published: January 2025

Kebijakan industri nasional melalui program hilirisasi industri memperlihatkan capaiannya, antara lain melalui kemitraan Industri Kecil Menengah (IKM) dan industri besar serta pengembangan usaha baru. Permasalahan rendahnya kerja sama antara IKM dan usaha besar tidak dapat dilepaskan dari karakteristik dan hambatan yang dihadapi oleh IKM, yang berakar dari kebijakan pemerintah. Oleh karena itu perlu dikaji bagaimana kebijakan atau regulasi dapat menempatkan IKM sebagai bagian dari industri nasional; dan bagaimana model kebijakan yang dapat mendorong percepatan hilirisasi industri strategis. Hasil penelitian menunjukkan bahwa salah satu upaya yang harus dilakukan agar tujuan hilirisasi industri strategis dan peningkatan global value chain adalah dengan melakukan transformasi UMKM agar mampu berkompetisi. Model pengaturan terintegrasi berperan penting dalam proses transformasi UMKM.
INTERNALISASI NILAI PANCASILA DALAM PRAKTIK DISKRESI BAGI PENGAMBILAN KEBIJAKAN
Authors: Surahno Surahno , Ruyadi Yadi , Nurdin Encep Syarief
Published: January 2025

Tulisan ini mengajak pembaca untuk menganalisis keberadaan diskresi dengan tidak terbatas pada hukum positif yang biasa dipergunakan oleh pendekatan hukum administrasi negara, melainkan dari sudut pandang hukum kodrat yang secara filosofis diisi oleh nilai-nilai ideologis seperti Pancasila sebagai sebuah recht ide negara yang bersifat lebih luas serta mendasari substansi aturan yang terkandung dalam hukum positif tersebut. Dengan mempergunakan metode kualitatif melalui studi kepustakaan teoretis-konseptual, tulisan ini mengklaim bahwa untuk mengatasi persoalan diskresi, diperlukan dua langkah terobosan, yakni menempatkan diskresi dalam kerangka hukum kodrat yang berbasis pada Pancasila dan menginternalisasi nilai-nilai Pancasila bukan lagi kepada muatan atau isi diskresi, tetapi kepada pejabat pemerintah sebagai pengguna diskresi itu sendiri. Selain itu, tulisan ini juga menyarankan agar pemerintah lebih memerhatikan Indikator Nilai Pancasila sebagai pedoman dalam pengambilan diskresi.
First record of the pill bug Armadillidium arcangelii Strouhal, 1929 (Crustacea: Isopoda) in Slovenia
Authors: Vittori Miloš
Published: January 2025

Numerous novel occurrences of Armadillidium arcangelii, a terrestrial isopod native to Italy, have been reported in recent years in synanthropic habitats across much of Europe. These records indicate that the species is rapidly spreading, likely via the transport of plants. On 21. 9. 2023, a male of this species was collected on turf near Seča on the Slovenian coast. This is the first record of A. arcangelii in Slovenia. The record is all the more relevant as A. arcangelii is a potential agricultural pest.

Role of circRMRP and circRPL27 in chronic obstructive pulmonary disease
Authors: Li JianFang , Zhang PengFei , Zeng XianJing , Liu Rong
Published: January 2025

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death and disability worldwide, and circRNA dysregulation is functionally associated with COPD. This study explored the potential of circRMRP and circRPL27 as biomarkers of COPD. Blood samples from COPD patients and healthy controls were collected. COPD patients were divided into mild, moderate, and severe groups according to lung function. Quantitative real-time polymerase chain reaction technology was used to determine the expression of circRPL27 and circRMRP in COPD. Receiver operating characteristic curve was drawn to explore the value of circRMRP and circRPL27 in diagnosing COPD. circRMRP and circRPL27 levels were elevated in serum of COPD patients and increased with the severity of COPD. CircRMRP and circRPL27 were associated with smoking history, WBC, and FEV1/FVC, and were positively correlated with smoking history and WBC, and negatively correlated with FEV1/FVC. In COPD, both circRMRP and circRPL27 had diagnostic values, but circRPL27 was better. circRMRP and circRPL27 may be useful non-invasive biomarkers for COPD diagnosis.
BA inhibits LPS-stimulated inflammatory response and apoptosis in human middle ear epithelial cells by regulating the Nf-Kb/Iκbα axis
Authors: He Qian , Cai Yanzhi , Kong Meihua
Published: January 2025

Otitis media (OM) is a prevalent childhood ear disease characterized by inflammation of the middle ear cavity, which can lead to ear pain, fever, and hearing loss. The pathogenesis of OM is multifaceted, encompassing a variety of factors including bacterial or viral infections, host immune responses, and the function of middle ear epithelial cells. Boswellic acid (BA), a natural triterpene compound extracted from frankincense resin, has been proven to possess significant anti-inflammatory and immunomodulatory effects. This study aims to investigate the effects of BA on lipopolysaccharide (LPS)-stimulated inflammatory responses and apoptosis in human middle ear epithelial cells (HMEECs) and its potential mechanisms. Our findings demonstrated that BA enhances the proliferation of LPS-stimulated HMEECs and concurrently inhibits their apoptosis. In addition, BA blocked LPS-stimulated HMEEC inflammation. Mechanistically, BA suppressed the NF-κB/IκBα axis in LPS-stimulated HMEECs. In conclusion, BA effectively inhibits LPS-stimulated inflammation and apoptosis by mediating the NF-κB/IκBα axis, highlighting its potential as a therapeutic agent for OM.

Published: January 2025

Moroccan Cannabis sativa L. seeds were investigated for their phenolic profile and antidiabetic potential. Ultra-high-performance liquid chromatography with diode array detection and electrospray ionization mass spectrometry analysis revealed a rich phenolic composition, including benzoic acid, cannabisin B, genistein, and epicatechin. In vitro, the seed extract exhibited potent α-amylase inhibitory activity (half-maximal inhibitory concentration = 25.02 ± 4.03 μg/mL). In vivo studies in diabetic rats demonstrated significant hypoglycemic, hypolipidemic, hepatoprotective, and nephroprotective effects. Molecular docking studies further supported these findings, revealing strong interactions between identified phenolic and the α-amylase enzyme. These results highlight the potential of C. sativa seeds as a natural source of bioactive compounds for diabetes management.

Humans as Donations and the Question of Temple Slavery in Early Mesopotamia
Authors: Bartash Vitali
Published: January 2025

This paper examines the practice of donating people to deities in southern Mesopotamia between 2600 and 2000 BC. It offers a diachronic analysis of Early Dynastic, Old Akkadian, and Ur III sources and considers Old and Neo-Babylonian evidence to address questions raised in Gelb’s (1972. “The Arua Institution.” RA 66: 1–32) foundational study. This paper demonstrates, first, that donors and recipients were rarely close relatives, as the dedicatees often included foreign captives, former slaves, orphans, and incomplete families temporarily under patronage prior to donation. Secondly, despite becoming temple “servants” (performing mostly unskilled labor like water-drawing, weaving, and, rarely, cult-related tasks), officials recorded the names of the donors of many dedicatees. In some cases, this was because the dedicatees were former slaves who continued living with their former masters after donation (and manumission), supporting them in old age as part of the paramonē arrangement. Other dedicatees may have lived with temple officials and employees or even within temple complexes. Third, the paper challenges the “temple slaves” model in interpreting the status of dedicatees in early Mesopotamia. Although third-millennium sources describe them as a deity’s “servants,” similar to how slaves in private households were referred to as someone’s “servants,” the dedicatees faced a social and legal dead end: temple officials could neither sell nor release them because their master or mistress was a deity. In effect, third-millennium dedicatees became part of a broader “menial” class of full-time temple dependents. Their status resembled that of the Neo-Babylonian oblates (širkū), who were legally free but subject to strict temple control. Finally, building on Patterson’s (1982. Slavery and Social Death. A Comparative Study. Cambridge, MA, London: Harvard University Press) model of slavery as a substitute for death, this paper argues that the donation of humans to temples in southern Mesopotamia functioned as an alternative to slavery. For the local impoverished population, donating family members to temples provided an option other than outright sale into slavery. Additionally, donating foreign captives to temples served as a more effective method of control and integration than enslavement.
Unveiling novel biomarkers for platinum chemoresistance in ovarian cancer
Authors: Wang Caixia , Peng Changsheng , Xie Chuan
Published: January 2025

Primary chemoresistance to platinum-based treatment is observed in approximately 33% of individuals diagnosed with ovarian cancer; however, conventional clinical markers exhibit limited predictive value for chemoresistance. This study aimed to discover new genetic markers that can predict primary resistance to platinum-based chemotherapy. Through the analysis of three GEO datasets (GSE114206, GSE51373, and GSE63885) utilizing bioinformatics methodologies, we identified two specific genes, MFAP4 and EFEMP1. The findings revealed that the areas under the receiver operating characteristic curves for MFAP4 and EFEMP1 were 0.716 and 0.657 in the training cohort, and 0.629 and 0.746 in the testing cohort, respectively. In all cases or in cases treated with platin, high expression of MFAP4 and EFEMP1 was linked to shortened overall survival and progression-free survival. MFAP4 and EFEMP1 were positively correlated with epithelial–mesenchymal transition, TGF-β signaling, KRAS signaling, and so on. The high expression groups of MFAP4 and EFEMP1 exhibited elevated stromal, immune, and ESTIMATE scores. Finally, we constructed a regulatory network involving lncRNA–miRNA–mRNA interactions. In summary, MFAP4 and EFEMP1 have the potential to serve as predictive indicators for both response to platinum-based chemotherapy and survival rates, and might be regarded as innovative biomarkers and therapeutic targets for OC patients.
Equiatomic transition metal (T) silicides TT′Si: systematics of 29Si NMR Knight shifts
Authors: Benndorf Christopher , Eckert Hellmut , Kösters Jutta , Pöttgen Rainer
Published: January 2025

A series of 64 ternary equiatomic tetrelides TT′Tt (T = electron-poor transition metal; T′ = electron-rich transition metal; Tt = Si, Ge) was synthesized by arc-melting and subsequent annealing. The samples were characterized by powder X-ray diffraction and 20 structures were refined from single-crystal X-ray diffractometer data. These tetrelides (mostly silicides) crystallize with TiNiSi-related structures, orthorhombic space groups Pnma. They are ternary ordered, orthorhombically distorted superstructure variants of the aristotype AlB2. The precise single-crystal data show distinct differences in the bond lengths and angles within the three-dimensional [T′Si] networks as a consequence of different electron densities driven by the electronegativity differences. Systematic solid-state NMR-spectroscopic investigations allow observing the effect of the two transition metal atoms upon the 29Si isotropic resonance shifts. For the silicides featuring T′ elements from groups IX and X this value can be predicted from element-specific increments.
An intermolecular Lewis pair based on tin acid and phosphonium ylide base functions
Authors: Meyer Peter , Neumann Beate , Stammler Hans-Georg , Mitzel Norbert W.
Published: January 2025

The tin-containing Lewis acid group (C2F5)3Sn was combined with a phosphonium ylide as base function in one molecule: o-[(C2F5)3Sn]-C6H4(Ph)2PCMe2. It was prepared by reacting the ortho-lithiated triphenylphosphoniumdimethylmethylide (o-Li-C6H4)(Ph)2PCMe2 with the stannyl chloride (C2F5)3SnCl to afford o-[(C2F5)3Sn]-C6H4(Ph)2PCMe2 in 86 % yield. It forms a ring structure with a bond between tin and the ylidic carbon atom both in solution and in the solid state and can thus be considered as a hidden frustrated Lewis pair. The title compound is unreactive towards H2, CO2, CS2, PhNCO and decomposes in the presence of SO2 or NH3. However, it is active in the catalytic reduction of CO2 with pinacolborane, H–BPin. The title compound reacts slowly with H–BPin in an unselective reaction from which a reduction product with cleaved C2F5 group, the phosphonium stannate (II) o-[(C2F5)2Sn]-C6H4(Ph)2PCHMe2, could be obtained in small amounts.
Cyanopyridine adducts of SiF4 and SiCl4
Authors: Riedel Sophie , Brendler Erica , Gericke Robert , Kroke Edwin , Wagler Jörg
Published: January 2025

The formation of cyanopyridine (CN-py) adducts of silicon tetrahalides was investigated for 3- and 4-cyanopyridine in combination with SiF4 and SiCl4. Whereas bubbling of SiF4 through toluene solutions of 3-CN-py and 4-CN-py afforded white precipitates, which should possess the respective composition SiF4(CN-py)2, addition of SiCl4 did not cause any precipitation. Upon storage of the toluene solution of SiCl4 and 4-CN-py at 6 °C for several weeks, some crystals of the composition SiCl4(4-CN-py)2 ⋅ 2 (4-CN-py) ⋅ (toluene) were obtained. The use of SiCl4 as the solvent (i.e. SiCl4 in large excess) and dissolving 4-CN-py therein gave access to a crystalline adduct of the composition SiCl4(4-CN-py)2 ⋅ 2 (4-CN-py). 3-CN-py instead recrystallized from SiCl4 without forming an adduct with the silane. Computational analyses (B2T-PLYP level) of the single-point energy differences between starting materials SiX
4 (X = F, Cl) and ‘pyridine’ (‘pyridine’ = pyridine, 3-CN-py, 4-CN-py) and their adducts SiX
4(‘pyridine’)2 revealed the tendencies toward adduct formation to decrease in the order SiF4 > SiCl4 as well as pyridine >> 4-CN-py > 3-CN-py. For SiCl4 with 4- and 3-CN-py, the energy of adduct formation (−7.0 and −5.7 kcal mol−1, respectively) is easily compensated by entropy effects at room temperature. Whereas the former explains as to why cyanopyridines and SiCl4 may co-exist without noticeable adduct formation, the crystal structures of the adducts SiCl4(4-CN-py)2 ⋅ 2 (4-CN-py) ⋅ (toluene) and SiCl4(4-CN-py)2 ⋅ 2 (4-CN-py) reveal the additional stabilization of these solids by co-crystallization with 4-cyanopyridine, which eventually enabled the isolation of the SiCl4(4-CN-py)2 moiety in a solid. Partial decomposition (hydrolysis) during attempts of recrystallization of SiF4(4-CN-py)2 and SiF4(3-CN-py)2 afforded crystals of the ionic compounds [4-CN-PyH]+[SiF5(4-CN-py)]– and [3-CN-PyH]+
2[SiF6]2–, respectively.

Investigating the Pass-Through Effect of Global Oil Price Shock on Domestic Inflation in Selected African Countries
Authors: Oyelami Lukman O. , Adekunle Babatunde S. , Oluwakemi Ademisola M.
Published: January 2025

The large-scale war between Russia and Ukraine has increased global oil prices, signaling a new era of macroeconomic shock management for both developed and developing countries. Consequently, this study investigates the passthrough effect of oil prices on domestic inflation in selected African countries in a single estimation framework using the global vector autoregressive (GVAR) estimation technique. To achieve the objective of this study, country-specific data were gathered from twenty-one African countries and four foreign countries selected based on trade relations. The results from our estimation demonstrate that the domestic general price level in African countries responds to global oil price shocks. Also, like any other part of the world, a disparity-like response is observable for African countries. This is tightly connected to whether the country is a metal-resource-rich, non-rich resource, or oil-rich country. The study thus concludes that positive shocks in the global price of crude oil will worsen the delicate position of the domestic general price level in non-oil-producing African countries. Efforts to minimize the impact of international oil shocks in these countries should center around investment in renewable energy and stabilization of the economy’s supply side through proactive and effective macroeconomic management.
Effect of Loading and Carbonation on the Compressive Strength and Hydraulic Conductivity of Solidified Sand
Authors: Aburaas Ghassan , Duhaime François , Dubé Jean-Sébastien
Published: January 2025

Cement-based solidification/stabilization (S/S) techniques have been widely used to produce stable forms of contaminated soils and reduce the mobility of contaminants into the environment. However, information on the long-term performances of S/S under environmental conditions (i.e., variable loading and atmospheric carbon dioxide) remains sparse. In this study, a triaxial test setup was modified to simulate environmental conditions. The permeability and compressive strength of silica sand solidified with portland cement were measured at different stages of four scenarios involving carbonation only, axial strain only, carbonation followed by axial strain, and axial strain followed by carbonation. X-ray computed tomography (CT) was used to characterize the internal structure of the samples. Permeability and compressive strength results indicate that the axial strain accelerated the damage to the S/S specimens and increased their permeability. The deterioration due to the mechanical strain decreased in the presence of carbon dioxide. Consistent changes in microstructure were observed with the CT scan. The results indicate that the influence of stressors on the void size distribution, compressive strength, and permeability is complex and characterized by interactions between the stressors.
Enhancing Online Job Shop Scheduling Efficiency: Simulation-Based Optimization Incorporating Human Productivity Factors and TOPSIS Ranking
Authors: Ahmadi Parham
Published: January 2025

The job shop scheduling problem is a classical optimization challenge aimed at determining the optimal processing order by assigning a set of resources to a corresponding set of operations. This article investigates various approaches to address the online job shop scheduling problem, employing a simulation-based study. Dispatching rules are applied to allocate resources to operations, with discrete event simulation used for problem assessment. The study also incorporates human productivity factors, specifically investigating the shortest processing time (SPT) dispatching rule in a separate scenario. Five distinct scenarios are simulated, including four dispatching rules (first in, first out; last in, first out; longest processing time; and SPT) and an additional scenario integrating the SPT rule and human productivity factors. The simulation results are used to compare makespan across these scenarios, revealing that the scenario involving the SPT dispatching rule and human productivity factors represents the shortest makespan. Through a TOPSIS technique-based ranking, considering makespan and cost as criteria, the study identifies the SPT rule and human productivity factors as the most efficient scenario. The findings imply that employing human productivity factors with effective dispatching rules, such as SPT, can significantly improve job shop scheduling operational efficiency and lead to more optimal results in both makespan and overall operational costs.

“Raiding Africa”: Motor Raid Films and Italian Economic Imperialism after the End of Colonial Empire
Authors: Dotto Simone
Published: January 2025

This essay explores a series of sponsored Italian nonfiction films representing trans-African car crossings, made after the dismantling of Italy’s colonial empire following World War II. I focus on two significant examples of what are commonly referred to as “motor raid films”—that is, film works shot during the Tripoli-Mogadishu and the Algiers-Cape Town crossings, produced by the main national nonfiction film companies, and sponsored by the major automotive firms between 1950 and 1952. Their production histories are traced using the film materials preserved by the Istituto Luce’s Archive and Archivio Nazionale Cinema Impresa, with reference to the corporate sources in Fiat’s and Alfa’s documentation centers. I investigate how cinema navigated the end of fascist territorial imperialism to become useful to the continuation of economic imperialism in the postwar free-market economy. Taking a cue from the scholarship on useful cinema and adopting an “infrastructural disposition,” I read these films as material and discursive manifestations of broader configurations of power and extraction. Their “usefulness” is then rethought in reference to what has been called the “automobility system” or “regime,” retracing how their production processes intersected the car companies’ extractive interests toward African lands. I argue that, while contributing to expand their markets, the motor raid films supported the car manufacturers’ arguments in favor of the extraction of labor in former Italian colonies and of raw materials in parts of the continent still dominated by other European powers. Ultimately, the films advocated an audiovisual and discursive “reframing” of Africa by representing it as a place of transit and of resource extraction, a mere testing ground for Western industries.
