Żydzi o Cyganach w II Rzeczypospolitej. Tematyka romska na łamach „Nowego Dziennika” (1918-1939)
Authors: Gontarek Alicja
Published: September 2022

Artykuł przedstawia problem stosunków cygańsko-żydowskich w II RP. Ma charakter przyczynkowy – skupia się na jednym tytule prasowym („Nowy Dziennik”), który jest najstarszym w Polsce pismem syjonistycznym, ukazującym się w języku polskim od 1918 roku. Analiza jego treści pozwoliła na wyciągnięcie kilku wniosków. Bezpośrednie relacje między dwiema mniejszościami – Cyganami i Żydami – prawie nie istniały, a strona żydowska, jeśli sporadycznie pisała o społeczności cygańskiej, dostrzegała jedynie negatywne konsekwencje takich kontaktów. Jeśli chodzi o postrzeganie Cyganów przez elity syjonistyczne, podtrzymywała ona wszystkie negatywne stereotypy i mity na ich temat, charakterystyczne dla społeczeństwa większościowego. Milczały też o państwotwórczych dążeniach Cyganów.

Entre el neutralismo y la confrontación: funciones del discurso referido en entrevistas políticas durante la polémica discursiva por las retenciones móviles en Argentina (2008)
Authors: Palma Alejandra Cecilia
Published: September 2022

Este trabajo se propone analizar las funciones del discurso referido en entrevistas políticas televisivas realizadas durante la polémica por las retenciones móviles desarrollada en Argentina en el año 2008 (Aronskind y Vommaro, 2010). El marco teórico integra elementos de la Teoría de la Argumentación en el Discurso (Amossy, 2014), el Análisis del Discurso Político Mediatizado (Fairclough 2005; Fetzer y Weizman, 2006) y el Análisis Conversacional (Heritage y Clayman, 2010). El corpus está compuesto por cuatro entrevistas realizadas en los programas de periodismo político A dos voces y Palabras más, palabras menos a dos dirigentes agrarios. Al enfocar el análisis en los procedimientos de citas directas e indirectas en las intervenciones de los entrevistadores, consideramos: 1) la distribución de las formas lingüísticas y el tipo de atribución; 2) las funciones de estas citas en el manejo de la agenda de la entrevista; y 3) algunos usos estratégicos identificados en cada programa. Los resultados revelan, por un lado, que el empleo de citas, en distintas funciones, constituye una herramienta clave para la práctica de entrevistar, y, por otro, que su uso estratégico parece apuntar hacia la configuración de distintas maneras de encarar el rol de entrevistador/a frente a una polémica discursiva.

Introduction: Organisms, including humans, have an internal biological clock that helps them adjust to the regular rhythm of the day. We aimed to study the effect of body's circadian rhythm (morning-evening), (biological clock) in searching for information on different people. Methods: The present study is of a fundamental applied type that has been performed by quasi-experimental method. The statistical population of the study consisted of 69 medical students of Qom University of Medical Sciences who were selected by purposive sampling method. The data of this study were used in two stages of completing the general health questionnaire, morning and evening sleep type, observing the behavior of completing search tasks and log analysis using collected images from users and then were collected in Camtasia studio software. Then, recorded data were collected and analyzed by Excel software and SPSS-24 software. Results: The results showed that people who slept in the evening had better information searching in a shorter time than people who slept in the morning and between. Analysis of the samples searching and retrieval behavior showed that they performed a total of 1574 strategies and techniques in the searching process. In fact, the samples chose their searching according to the type of their task. Conclusion: None of the sleeping types can affect the tests and cause cycles. Based on the genetic changes that occur, humans have different characteristics changing from time to time and create individual and functional differences. The range of individual differences is much wide.

controlled trial

Authors: Couzos S , Lea T , Mueller R , Murray R , Culbong M
Published: September 2022

Objectives: To compare the effectiveness of ototopical ciprofloxacin (0.3%; CIP)
with framycctin (0.5%), gramicidin, dexamethasone (FGD) eardrops (5 drops twice daily
for 9 days), together with povidone-iodine (0.5%) ear cleaning, as treatments for
chronic suppurative otitis media (CSOM) in Aboriginal children.
Design and
Participants: Aboriginal community-controlled, community-based, multicentre,
double-blind, randomised controlled trial in eight Aboriginal Community Controlled
Health Services across northern Australia, involving 147 Aboriginal children with
CSOM.
Main Outcome Measures: Resolution of otorrhoea (clinical cure), proportion of
children with healed perforated tympanic membrane (TM) and improved hearing, 10-21 days
after starting treatment.
Results: 111 children aged 1-14 years (CIP, 55; FGD, 56)
completed treatment. CSOM cures occurred in 64% (CIP, 76.4%; FGD, 51.8%), with a
significantly higher rate in the ciprofloxacin group (P = 0.009, absolute difference of
24.6% [95% CI, 15.8%-33.4%]). TM perforation size and the level of hearing impairment
did not change. Pseudomonas aeruginosa was the most common bacterial pathogen (in

Language ability after early detection of permanent childhood hearing
impairment

Authors: Kennedy CR , McCann DC , Campbell MJ , Law CM , Mullee M , Petrou S , Watkin P , Worsfold S , Yuen HM , Stevenson J
Published: September 2022

Background: Children with bilateral permanent hearing impairment often have
impaired language and speech abilities. However, the effects of universal newborn
screening for permanent bilateral childhood hearing impairment and the effects of
confirmation of hearing impairment by nine months of age on subsequent verbal abilities
are uncertain.
Methods: We studied 120 children with bilateral permanent hearing
impairment identified from a large birth cohort in southern England, at a mean of 7.9
years of age. Of the 120 children, 61 were born during periods with universal newborn
screening and 57 had hearing impairment that was confirmed by nine months of age. The
primary outcomes were language as compared with nonverbal ability and speech expressed
as z scores (the number of standard deviations by which the score differed from the mean
score among 63 age-matched children with normal hearing), adjusted for the severity of
the hearing impairment and for maternal education.
Results: Confirmation of hearing
impairment by nine months of age was associated with higher adjusted mean z scores for
language as compared with nonverbal ability (adjusted mean difference for receptive
language, 0.82; 95 percent confidence interval, 0.31 to 1.33; and adjusted mean
difference for expressive language, 0.70; 95 percent confidence interval, 0.13 to 1.26).
Birth during periods with universal newborn screening was also associated with higher
adjusted z scores for receptive language as compared with nonverbal ability (adjusted
mean difference, 0.60; 95 percent confidence interval, 0.07 to 1.13), although the z
scores for expressive language as compared with nonverbal ability were not significantly
higher. Speech scores did not differ significantly between those who were exposed to
newborn screening or early confirmation and those who were not.
Conclusions: Early
detection of childhood hearing impairment was associated with higher scores for language
but not for speech in mid childhood. Copyright 2006 Massachusetts Medical Society.

Organic solvents and hearing loss: The challenge for
audiology

Authors: Fuente A , McPherson B
Published: September 2022

Organic solvents have been reported to adversely affect human health, including
hearing health. Animal models have demonstrated that solvents may induce auditory
damage, especially to the outer hair cells. Research on workers exposed to solvents has
suggested that these chemicals may also induce auditory damage through effects on the
central auditory pathways. Studies conducted with both animals and humans demonstrate
that the hearing frequencies affected by solvent exposure are different to those
affected by noise, and that solvents may interact synergistically with noise. The
present article aims to review the contemporary literature of solvent-induced hearing
loss, and consider the implications of solvent-induced auditory damage for clinical
audiologists. Possible audiological tests that may be used when auditory damage due to
solvent exposure is suspected are discussed.

Chronic suppurative otitis media in school pupils in
Nigeria

Authors: Ologe FE , Nwawolo CC
Published: September 2022

Objective: To compare the prevalence of chronic suppurative otitis media (CSOM)
among two populations of school children. Design: A survey-demographic data collection
and otoscopy was carried out among the two populations of school children. Setting: A
rural government primary school and an urban private primary school. Subjects: Six
hundred and ninety-nine school pupils in the rural school and two hundred and seventy
pupils in the urban school. Results: Six per cent of the pupils in the rural schools had
CSOM as evidenced by persistent perforation of tympanic membrane of more than three
months duration. No tympanic membrane perforations were observed in the children in the
urban school at the time of this study. The difference in the prevalence of CSOM between
the two populations is statistically significant (P < 0.001). The difference in
socio-economic status between the two populations is statistically significant in
relation to the prevalence of CSOM in the two populations. The poorer rural population
had a significantly higher prevalence of CSOM (P < 0.001). Conclusion: The two study
populations are just seven kilometres apart geographically but there is a world of
difference in their socio-economic status, availability of social infrastructure and
health facilities. This presumably had reflected in the marked difference in the
prevalence of CSOM between the two study populations. A collective effort of government
and well meaning indigenes of rural communities in Nigeria can help promote the
socio-economic status and enhance the availability of social infrastructure and health
facilities of rural areas. This we hope will lead to a decline in the prevalence of CSOM
in the rural areas. Published courtesy of:East Afr Med J. 2003; 80(3): 130-134
Analytical Model for Mechanical Formation Damage Control in Permeability-Hysteretic Oil Reservoirs
Authors: Fernandes F. B. , Braga A. M. B. , Souza A. L. S. , Soares A. C.
Published: September 2022

Several analytical solutions for the hydraulic diffusivity equation (HDE) in poro-elastic reservoirs with constant permeability are available in the petroleum engineering literature. Although, the mathematical modeling of the permeability pressure-sensitive effect through the nonlinear hydraulic diffusivity equation (NHDE) still constitutes a challenge in the petroleum industry. This work presents a new transient two dimensional (2-D) analytical model for oil flow in an infinite permeability- hysteretic pressure-sensitive reservoir during alternating loading/unloading cycles. Two new hydraulic diffusivity deviator factors are presented for drawdown and build-up periods in order to represent the permeability deviation during the drawdown and its partial restoration in the build-up period. When the well is open to flow, the results show clearly the permeability deviation compared to the linear solution (constant permeability), as well as, when the well is shut, the hysteresis-response is also noticed on the diagnostic plots. The model calibration is performed by a numerical oil flow simulator, widely used in the reservoir engineering literature. The accuracy, ease implementation and the low computational costs constitute the main advantages related to the developed model. Therewith it may be a useful and attractive mathematical tool to support the well-reservoir performance management.

1 INTRODUCTION

Minimizing the economic impairments caused by the permeability-hysteresis effect in pore pressure-dependent porous media during the alternating oil loading/unloading cycles is essential to prevent premature wells abandonment and field disinvestments.

Extensive analytical solutions for the hydraulic diffusivity equation (HDE) in poro-elastic reservoirs with constant permeability are available in the literature, (Peres et al., 1989; Chin et al., 1998). Commonly the solutions developed for these cases are developed through Fourier and Laplace transform or Boltzmann transformation, (Fernandes, 2021a,b; Fernandes et al., 2021a; Fernandes, 2022; Fernandes et al., 2022). However, the mathematical modeling of the permeability pressure-dependent effect through the nonlinear hydraulic diffusivity equation (NHDE) with source term still constitutes a challenge for geoscientists, formation evaluation and reservoir engineers.
Study on Strength of Rock Salt with Mudstone Based on the Hoek-Brown Criterion
Authors: Ye Liangliang , Chen Feng , Xue Tianfu , Wang Wenquan
Published: September 2022

According to the short-term strength of rock salt with mudstone, the applicability of Hoek-Brown criterion to the strength of rock salt with mudstone is studied. Uniaxial and triaxial compression tests have been carried out on rock salt with mudstone samples of Jintan gas storage to analyze the short-term strength and deformation characteristics of rock salt. The rock salt shows obvious strain hardening under the confining pressure of over 5 MPa. In order to study the volumetric strain characteristics of rock salt with mudstone, the stress corresponding to the strain of 4% is selected as the strength to discussed. Different strength criteria are compared to analyze the strength of rock salt, the result shows that the Hoek-Brown criterion has a good fit effect. The Hoek-Brown model is used in FLAC3D to simulate the triaxial strain hardening of rock salt with mudstone. By modifying the plastic deformation proportionality coefficient γ in the model, a new calculation equation of γ is proposed, and the deviatoric stress and volumetric strain curve obtained by the modified model are in good agreement with the experimental curve, which verifies its rationality.

1. INTRODUCTION

As a national strategic issue, energy reserves can prevent energy crises caused by war and can adjust the imbalance of production and use, so they are highly valued. Rock salt is considered to be an ideal medium for oil and natural gas storage and for radioactive waste disposal because of its excellent characteristics such as damage self-recovery, low porosity, low permeability, and large plastic deformation ability (Yin et al., 2019). Therefore, gas storage caverns in rock salt are widely used and studied in the world.

Since the gas storage cavern in rock salt has a strategic reserve application background, in order to make them better used in engineering practice, many scholars have done a lot of research on rock salt. The strength of rock salt is an important characteristic. However, there are more studies on the long-term strength of rock salt, but fewer on its short-term strength. The short-term strength of rock salt mainly refers to the experimental characteristics and theoretical analysis of rock salt under uniaxial and triaxial stress without considering the time effect, and the establishment of the strength and deformation theory of rock salt. Liang et al. (2006) performed a linear regression on the rock salt strength curve and obtained the regression equation. Ma et al. (2015) assumed that the relationship between the maximum and minimum principal stress was linear. Sriapai et al. (2013) conducted true triaxial tests on the rock salts of Mahasarakham, and determined the cohesion and internal friction angle of rock salt based on the Coulomb criterion.
Impact of Biogeomechanical Process on CO2 Sequestration in Hydrocarbon-Depleted Carbonate Reservoirs
Authors: Kolawole O. , Ispas I. , Schwartz B.
Published: September 2022

Carbon dioxide (CO2) sequestration in depleted oil and gas reservoirs is a key technology to mitigate anthropogenic CO2 emissions. In this study, we experimentally investigate the impact of biogeomechanical alteration on CO2 storage in a hydrocarbon-depleted carbonate reservoir using core samples from a deep carbonate formation in the Permian Basin United States. We first obtain the mechanical and microstructural properties of the carbonate samples using the scratch test method, and we treat the samples with a bacteria strain at distinct conditions. Then we expose the samples to CO2 in a supercritical state (ScCO2) for 21 days. We obtain the post-treatment properties of the microbially-treated samples and analyze the effect of the modified properties on long-term CO2 storage in the carbonate formation. Our results indicate that in hydrocarbon-depleted carbonate reservoirs, microbially-altered properties can enhance mechanical integrity and provide potential long-term security for stored CO2.

1 INTRODUCTION

Carbon capture and storage (CCS) in geologic formations is a key technology for climate change to mitigate anthropogenic CO2 emission (Holloway, 1997; Lackner, 2003; Lebedev et al., 2017; Badghaish and Schwartz, 2021; Kolawole et al., 2021a; Ozotta et al., 2021a; Schwartz, 2022). Geologic media such as saline aquifers (Langenfeld et al., 2017a), limestone (Gozalpour et al., 2005; Lebedev et al., 2017), sandstone, basalt (Langenfeld et al., 2017b; Menefee and Ellis, 2021), and shale (Fatah et al., 2021a, 2021b; Kolawole et al., 2021a, 2021b, 2021c; Onwumelu et al., 2021; Ozotta et al., 2021a, 2021b, 2021c) are potential target CO2 storage reservoirs.

Biogeomechanics is an emerging field of geomechanics that investigates geomechanical responses of microbial-rock interactions (Kolawole et al., 2021a, 2021b, 2021c). The microbe, Sporosarcina pasteurii (ATCC® 11859™) (Yoon et al., 2001), is observed to rapidly precipitate calcite in sand columns as the bacteria growth increases, for selective cementation and plugging of porous media (Stocks-Fischer et al., 1999; Kolawole et al., 2021a, 2021b).
Study on Scale Effect of Soil-Rock Mixture Based on Model Test and PFC
Authors: Wei Zhang , YaDong Xue
Published: September 2022

Soil-Rock Mixture (S-RM) are widely found in the mountainous areas of southwestern China. The study of rock mechanical properties of S-RM is of great significance for preventing and controlling landslides or other geological disasters. Due to the large differences in rock content and particle gradation, the mechanical properties of S-RM show significant scale effects. This article discusses the "Representative elementary volume" (REV) properties of the S-RM under the condition of different rock-soil volume ratios. Based on the indoor biaxial experiment, the paper firstly establishes a two-dimensional discrete element model suitable for S-RM; Secondly, considering the rock content, by numerical simulation method based on PFC discrete element software, a total of 126 sets of biaxial tests were performed to obtain the cohesion and internal friction angle of the S-RM. By analyzing systematically experimental data of PFC, the corresponding scale effect curves are fitting. After the samples overcome the scale effect, the REV laws of the S-RM under different control variables are obtained. The engineering scale of the S-RM samples is about 600×200 mm. In actual projects, this sample size can be selected for testing or numerical simulation to reduce the scale effect.

1. INTRODUCTION

Soil-rock mixture was defined by Xu and Hu (2009) as an extremely inhomogeneous and loose geotechnical material composed of rocks with high strength at a certain engineering scale, pore spaces and soil particles. Soil-rock mixtures are widely distributed throughout China, especially in the southwest. Landslide mounds and rock piles commonly found in southwestern mountainous areas are mostly composed of soil-rock mixtures. Due to the inhomogeneity of soil-rock mixture, mechanical properties have large spatial variability so that the study of mechanical properties and ontological characteristics are very difficult. The study of soil-rock mixtures is significant for the prevention and control of geological hazards such as landslides and collapse.
Effect of Supercritical CO2 on Permeability and Surface Characteristics of Fractures in Shales
Authors: Hashemi S. S. , Zoback M. D.
Published: September 2022

The impacts of supercritical carbon dioxide (scCO2) on fracture permeability and fracture surface characteristics of shale samples with various mineral compositions were studied in this paper. We measured permeability and fracture normal displacement (FND) at different confining pressures and pore pressures using both argon gas and scCO2. Our results indicate that mechanical compaction and fine particles migration have opposite impacts on permeability and FND, especially in clay-rich shales. It appears that fine particle migration creates a self-propping aperture that results a permeability increase in the subsequent cycle. However, inelastic compaction associated with loading/unloading cycles reduce the permeability. In addition, an increase in permeability (and associated fracture surface degradation) were observed after more than 3 days of exposure to scCO2 due to carbonate dissolution. The rates of permeability increase in saw cut fractures are larger than FND suggesting that new flow pathways were created because of carbonate dissolution and that controls the transport characteristics of the scCO2-interacted fracture surface.

1. INTRODUCTION

Geological carbon capture and storage (CCS) is one of the techniques to reduce green gas emissions and storage of CO2 in unconventional reservoirs has been the focus of many studies in the last few years (Goodman et al. 2020; Kim et al. 2017; Kolawole et al. 2020). Methane is found as a free phase in pores and fractures and also as adsorbed gas on clay or organic matter in shale gas plays. After the reservoir is depleted, CO2 could be sequestrated by similar mechanisms as methane in two populations. Supercritical CO2 (scCO2) has been also proposed as an alternative fracturing fluid for hydraulic fracturing operations in unconventional reservoirs (Ishida et al. 2012; Jia et al. 2019; Zhang et al. 2017). The phase diagram for carbon dioxide shows that CO2 behaves as a supercritical fluid that adopts properties somewhere between a gas and a liquid above the critical temperature and critical pressure of 31.1 °C and 7.37 MPa, respectively. Compared to aqueous-based fluids, scCO2 can develop more complicated fracture networks, improve shale gas recovery by preferential adsorption behaviors of CO2 over methane, reduce flow blockages and reduce water consumption (Zhou et al. 2020). For instance, a study on Yan-2011 shale gas by Li and Kang, (2018) showed that after scCO2 fracturing, the CO2-retention rate was 39.5% and the shale gas production rate was increased 1.5 times. Nevertheless, scCO2 has a lower viscosity than water in the reservoir temperature and pressure and that reduces its efficiency of carrying proppants into the fracture networks.
Pensamento Computacional na Educação Brasileira: um olhar segundo artigos do Congresso Brasileiro de Informática na Educação
Authors: Carvalho Felipe , Braga Marco
Published: September 2022

Em 2006, Jeannette Wing publicou um artigo no qual afirma ser importante o desenvolvimento de uma competência básica em todos os estudantes da Educação Básica. Essa competência, inerente ao profissional da computação, foi denominada de Pensamento Computacional. O termo ganhou relevância a partir de sua publicação e diversos trabalhos começaram a ser desenvolvidos. Com objetivo de entender um pouco melhor como esse termo tem sido utilizado e o sentido a ele atribuído, procedemos a uma revisão dos artigos publicados entre os anos de 2015 a 2019 no Workshop de Ensino em Pensamento Computacional, Algoritmos e Programação (WalgProg) que ocorre no âmbito Congresso Brasileiro de Informática na Educação (CBIE). Os resultados apontam que ainda há muitas publicações que citam o termo de maneira descontextualizada ou atribuem a ele significados errôneos, porém, pudemos observar uma crescente preocupação em trazer maior embasamento ao termo quando esse surge no trabalho, destacando-se o potencial interdisciplinar do Pensamento Computacional, especialmente associado à resolução de problemas.

A pandemia causada pela Covid-19 impactou a população de maneira considerável. As escolas tiveram que mudar as formas de ensinar, reinventando práticas e ações pedagógicas para que os estudantes pudessem aprender nessa nova rotina de ensino remoto emergencial. Diante da necessidade de buscar novas práticas de ensino, a gamificação, de modo especial, a gamificação personalizada (e.g., gamificação social e gamificação baseada em performance) são alternativas para melhorar a qualidade do ensino remoto emergencial. No sentido de analisar essas possibilidades, realizamos um estudo primordialmente qualitativo (baseado no método de Bardin) conduzido inicialmente com 17 estudantes e uma professora, para entender como gamificação social e a gamificação baseada em performance podem afetar o processo de ensino e aprendizagem no cenário de ensino remoto emergencial. Os resultados demonstram que esses diferentes designs de gamificação podem afetar de maneira positiva a experiência no ensino remoto, mas também evidenciou a necessidade de se entender mais a fundo como cada design de gamificação afeta a experiência dos estudantes de acordo com seus perfis. Assim, nosso estudo contribui para áreas de tecnologias na educação e gamificação, por meio de insights para a personalização de sistemas educacionais gamificados.
A Quanti - Qualitative stakeholder analysis of rural English language learners’ essay writing errors
Authors: Ngoepe Lucia Junia , Mailula Maphefo Rebecca
Published: September 2022

English First Additional Language (EFAL) Error Analysis (EA) elevates the status of errors from being undesirable to significant as errors tend to afford the educator researcher an opportunity to identify and tackle learners’ language errors optimally. Additionally, learners deserve space to practise essay writing. The research was premised on EA; EFAL learners’ written essays were analysed and educators were interviewed on the learners’ essay writing errors, respectively. Purposive sampling was used to collect data from the stakeholders; learners’ written essays and interview responses of the educators on EFAL essay writing errors. The findings suggest that EFAL educators should be adept at identifying and analyzing essay writing errors of learners of all hue in South African rural public schools. Thus, learners and educators need to work in concert towards correcting and in the long term, eradicating essay writing errors.
Revision of the genus Dicranopalpus from northern Spain and Corsica, with descriptions of two new species (Arachnida, Opiliones, Phalangioidea)
Authors: Wijnhoven Hay , Martens Jochen , Prieto Carlos E.
Published: September 2022

The Iberian Peninsula represents a diversity hotspot for the genus Dicranopalpus. However, most taxa are insufficiently defined. Our revision of the Dicranopalpus pyrenaeus species group reveals two hidden species: D. catariegensis sp. nov. and D. gallaecicus sp. nov. Two species, D. pyrenaeus from the Spanish and French Pyrenees and D. insignipalpis from Corsica, are redescribed. Dicranopalpus cantabricus Dresco, 1953 is resurrected as a valid species. Three new synonyms of D. martini (Simon, 1878) are proposed: Fagea bolivari Dresco, 1949 (including D. bolivari sensu Rambla 1975), Egaenasser extraordinarius Roewer, 1953 and Dicranopalpus dispar Rambla, 1967. With these additions, the Iberian Peninsula harbours four species of the Dicranopalpus pyrenaeus species group. They largely have allopatric distributions, ranging from the Pyrenees and the Cantabrian mountain range to the west coast of Galicia.
Buddhism, Sāṃkhya and the Brahmanical Avant-Garde
Authors: McGovern Nathan
Published: September 2022

The opening chapter proposes that early Buddhism should be understood not as having arisen in opposition to a monolithic Brahmanism – traditionally its first ‘other’ – but rather out of the avant-garde of Brahmanism itself, which would have been quite fluid and diverse in thought and praxis in the fifth century BCE. McGovern argues that the Buddha’s tutelage under Āḷāra Kālāma and Uddaka Rāmaputta is key to understanding early Buddhism’s place within the Brahmanical avant-garde. Alex Wynne has shown that the forms of meditation taught by these two teachers make most sense in the context of Brahmanical cosmologies. Such a connection is further supported by the testimony of Aśvaghoṣa (c. C2nd), who presents Āḷāra Kālāma as espousing an early form of Sāṃkhya. The chapter argues that Buddhism emerged out of a branch of fifth-century-BCE Brahmanical thought that was first demonized by householder Brahmans, and then later codified and included within orthodox Brahmanism as Sāṃkhya. Although the connections between Buddhism and Sāṃkhya have long been a focus of scholarly interest, neither derived from the other; both were identities that emerged much later out of intellectual currents at play in the fifth century BCE.
Demons, Wicked Ones and Those Who Violate the Samaya s: Dharma Against the Enemy in Tantric Buddhism
Authors: Wenta Aleksandra
Published: September 2022

This paper analyses the ways in which tantric Buddhists represent the religious other, i.e., Śiva-Maheśvara, in texts that consolidate the image of Maheśvara as a demon and a wicked one. Against the theory of social crisis as a reason for the emergence of Buddhist tantras that propagate violence, this paper demonstrates that tantric Buddhist conceptions of evil that include in their borders Maheśvara were formulated through the distinctive adoption of the magical technology of abhicāruka that became creatively reconfigured to include a moral dimension, thus becoming what I am calling “dharma against the enemy”. These were rituals founded primarily on a moral paradigm motivated by the vision of a moral reform that would include in its borders both non-Buddhists and Buddhist practitioners who strayed from their path, and not – as some scholars have proposed – a response to interreligious conflict. Moreover, the adoption of the term duṣṭa in reference to the target of aggressive magic, in both the Śaiva and the Buddhist tantras, reflects both these traditions’ alignment of their discourse to legal imaginaries prevalent in India in the second half of the first millennium CE.
Burckhardt’s (New) World and Ours: Rethinking the Renaissance in the Age of Global History
Authors: Marcocci Giuseppe
Published: September 2022

Part 4 of Jacob Burckhardt’s Civilisation of the Renaissance in Italy (1860) greatly contributed to the shaping of an interpretation of the so-called ‘age of exploration’ that was still influential until a few years ago. This was largely due to its inspiring title, ‘The Discovery of the World and of Man’. This chapter discusses the cultural background to Burckhardt’s successful idea, its dissemination across the literature about the discovery of America, and its impact on 20th-century historiography about the age of exploration, which has been especially affected by the ‘global turn’ in historical studies. A few examples of transcultural interactions on a global scale, relating to the writing of histories of the world and their reliance on oral sources and a plural notion of antiquity, are used to explain why and how our view of the New World has moved away from Burckhardt’s. Ultimately, however, it is argued that a critical reappraisal of Burckhardt may still support current attempts to develop a much more complex and multifaceted understanding of the Renaissance.
Burckhardt, Religion, and the ‘Principle of Correction’: From Renaissance to Reformation
Authors: Bauer Stefan
Published: September 2022

As a young man, Jacob Burckhardt, son of the highest-ranking Protestant preacher in Basel, started studying theology but then suffered a religious crisis and became a historian. Throughout his life, Burckhardt reflected on the relationships among religion, secularisation, politics, and culture. These thoughts were expressed in his Civilisation of the Renaissance in Italy, but also in his lectures on early modern history. His presentation of the Reformation went strongly against the blueprint of optimistic Protestant historiography. Applying what has been labelled as a ‘principle of correction’, Burckhardt painted a gloomy picture of both the Lutheran Reformation and Calvinism; they were violent and destructive. In addition, Burckhardt also corrected prevalent notions about the Italian Reformation. The Reformation failed in Italy, not because it was suppressed by the Catholic authorities—as was usually assumed—but because Renaissance Italians possessed a mentality that was too ‘modern’ to be able to create new dogmas.
‘Noble ambition’: New Social Literacies and Traditional Hierarchies in Early Modern European Literature and History
Authors: Boutcher Warren
Published: September 2022

This chapter considers the applicability of Sheldon Pollock’s framework for the analysis of the ‘vernacular millennium’ in Europe and south Asia to the history of the relationship between letters and learning and social hierarchy in Europe from the 1530s to the 1660s. Pollock is interested in processes of literisation, literarisation, superposition, in moments when both (i) writing per se and (ii) literature that is formed on superior, foreign models irrupt into societies for the first time. The chapter also examines how vernacular texts from 1580 to 1620 represent the irruption of new forms of social literacy into societies shaped by traditional customs, beliefs, and hierarchies. It discusses the example of Montaigne’s Essais, then moves on to other examples from English Renaissance drama (especially Shakespeare, Henry Sixth Part Two and Henry VIII) and Spanish prose fiction. They all reckon with the early modern fear that new knowledge and new language skills, in combination with ambition for power and status, could disrupt the peaceful reproduction of natural hierarchies and orders, including traditions of ancient and pure religion, and thereby give rise to social malaise and destruction.
Magnates and Military Contracting in Hungary after 1648
Authors: Oross András
Published: September 2022

In the 1650s about a quarter of the new peacetime standing army of the Habsburg Monarchy (c. 5000 soldiers) served for a time in one of the castles on the Hungarian-Ottoman frontier. Organising the upkeep of these soldiers was coordinated by the central authorities in Vienna with the collaboration of the Bohemian and Austrian lands as well as the Hungarian Estates. The kingdom of Hungary – a theatre of war since the 1520s – participated in the Habsburg fiscal-military state primarily through the provision of resources in kind (grain and wine), rather with taxes paid in cash. Contractors drawn from among Hungarian magnates and military officers played a key role in this business.
