Authors: Martins Meurer Alison , Lopes Iago França , Costa Flaviano , Colauto Romualdo Douglas
Published: November 2023

Introdução/objetivo: as redes sociais permitem a autodeclaração de emoções que dificilmente seriam observadas no ambiente físico. Nesse contexto, este estudo busca analisar a relação entre as experiências com a pós-graduação e as emoções autodeclaradas nas redes sociais. Complementarmente, busca identificar diferenças na percepção dos respondentes conforme as características pessoais. Metodologia: os dados obtidos junto aos discentes do stricto sensu totalizaram 1173 participações. A análise consistiu em testes de diferenças entre grupos e modelagem de equações estruturais. Resultados: os resultados revelam que as emoções positivas são influenciadas pela organização do curso, pelas relações interpessoais e pelo apoio ao desenvolvimento acadêmico, no modelo geral. Enquanto as emoções negativas são afetadas pela organização do curso e pelas relações interpessoais, no modelo geral, e pela estrutura institucional e pela organização do curso, para o modelo restrito à área de ciências sociais aplicadas. Conclusões: a pesquisa demonstra que as emoções que os estudantes brasileiros compartilham nas redes sociais são afetadas pelas vivências durante a pós-graduação e estão sujeitas a variações de acordo com as características únicas de cada aluno. Adicionalmente, o estudo sublinha a relevância de acompanhar de perto as emoções manifestadas pelos estudantes em ambientes virtuais, uma vez que esses dados podem oferecer insights preciosos para a administração dos programas de pós-graduação.
Working on Concepts as an Element of Communication and Starting Point for research-based Learning in Higher Education
Authors: Rieber Viktoria , Vocilka Anja , Albers Stine , Gaubitz Sarah , Blanck Bettina
Published: November 2023

Viktoria Rieber, Anja Vocilka, Stine Albers, Sarah Gaubitz & Bettina Blanck discuss in this article, that knowing what words mean is the basis for successful verbal communication. For scientists, problem-appropriate explanations of terms are central. Teachers also need a horizon of meaning possibilities to access the diversity of students' conceptions and to recognize the creative potential for school-based conceptual clarification work. They want to sketch out a seminar that centers on interdisciplinary conceptual clarification work with and by students. It will become clear how much the seminar thrives on controversy and varied perspectivity. If one considers education as a critical-reflective process of the involvement of the self with itself and the world, it is particularly suitable for research-seeking educational processes to start conceptual clarification work on specific subjects and the concepts that belong to them. The article presents exploratory work with topic-related concepts (appertaining, for instance, to Work, Family, Justice, or Sustainability) in the context of higher education, and, in doing so shows possibilities of how this can be supported by digital formats.
Sense-making in the Production Process of Online Learning Materials
Authors: Krüger Michael
Published: November 2023

Creating online learning materials in an international team requires a shared understanding of the intended outcome of all team members. This article highlights the results of the sense-making process we went through as part of the IDEN project to jointly develop materials for asynchronous online learning. It describes the challenge we had to find a solution for and introduces the common language and a concept of a production process that helped us to work together. While the collaborative process of organizing is the focus of interest, this article is located in the area of education management.
Umkämpfte Gerechtigkeit
Authors: Kalt Tobias
Published: November 2023

Transformationskonflikte werden häufig vehement geführt. Dies liegt auch daran, dass es nicht allein um technische Fragen der Dekarbonisierung, sondern um Gerechtigkeit geht. Die Erkenntnis, dass sozial-ökologische Transformationsprozesse an Gerechtigkeitsprinzipien ausgerichtet sein müs- sen, hat sich inzwischen in der Transformationsdebatte durchgesetzt (siehe Morena/Krause/Stevis 2019). Doch wie sieht eine gerechte Transformati- on aus, wenn unterschiedliche Vorstellungen von Gerechtigkeit kursieren und gegensätzliche Anforderungen an Transformationsprozesse gestellt werden? Insbesondere Gewerkschaften und Klimabewegungen geraten mit ihren unterschiedlichen und teils widerstreitenden Interessen, Zielen und Gerechtigkeitsvorstellungen immer wieder in Transformationsprozessen in Konflikt (Räthzel/Stevis/Uzzell 2021). Beim Kohleausstieg in Deutschland wird dies besonders deutlich. Hier wird darum gekämpft, was eine gerechte Transformation ausmacht und inwiefern die Gerechtigkeitsvorstellungen der Beschäftigten in fossilen Industrien, der Anwohner:innen am Rande der Tagebaue, der jungen und zukünftigen Generationen oder der am stärksten vom Klimawandel betroffenen Menschen im globalen Süden berücksichtigt werden.

Published: November 2023

This study aimed to chemically isolate two distinct types of nanocellulose derived from rubber leaves and investigate their use in natural rubber (NR). The cellulose nanocrystals (CNCs) were obtained through acid hydrolysis, while oxidation with 2, 2, 6, 6-tetramethylpiperidine-1-oxyl (TEMPO) was used to produce cellulose nanofibers (CNFs). The CNCs exhibited rigid and rod-like structures due to the removal of amorphous regions through acid hydrolysis, whereas the CNFs retained flexible, fiber-like morphologies and high aspect ratios. Incorporating CNCs or CNFs into NR improved its tensile properties, with the rigid CNCs enhancing the mechanical properties more than the flexible CNFs. CNC addition resulted in a 40% increase in tensile strength and a 38% increase in Young's modulus of NR. However, elongation at break decreased with filler content. On the other hand, CNF addition improved the elongation at the break without compromising the tensile properties. NR with CNF addition exhibited a 25% increase in tensile strength, a 30% increase in Young's modulus, and a 20% increase in elongation at break. Additionally, the biodegradability of NR nanocomposite films containing CNCs or CNFs surpassed that of unfilled NR film. Notably, a 6-month soil burial test revealed weight losses of 35% and 40% for NR nanocomposite films with CNCs and CNFs respectively, compared to a weight loss of 25% for the unfilled NR film.

Authors: Narayanan Muthalagappan
Published: November 2023

Space cooling and heating always tends to be a major part of the primary energy usage. By using fossil fuel electricity for these purposes, the situation becomes even worse. One of the major electricity consumptions in India is air conditioning. There are a lot of different technologies and few researchers have come up with a debate between solar absorption cooling and PV electric cooling. In a previous paper, PV electric cooling was studied and now as a continuation, this paper focuses on solar thermal absorption cooling systems and their application in commercial/office buildings in India. A typical Indian commercial building is taken for the simulation in TRNSYS. Through this simulation, the feasibility and operational strategy of the system is analysed, after which parametric study and economic analysis of the system is done. When compared with the expenses for a traditional air conditioner unit, this solar absorption cooling will take 13.6 years to pay back and will take 15.5 years to payback the price of itself and there after all the extra money are savings or profit.  Although the place chosen for this study is one of the typical tropical place in India, this payback might vary with different places, climate and the cooling demand.Article History: Received May 12th 2017; Received in revised form August 15th 2017; Accepted 1st Sept 2017; Available onlineHow to Cite This Article: Narayanan, M.

Hauptsätze mit Verbspäterstellung im Althochdeutschen: Bestand, Distribution, Interpretation
Authors: Petrova Svetlana
Published: November 2023

This corpus study investigates well-known violations of the verb second constraint in Old High German main clauses. Starting from the observation that the attested orders are overwhelmingly ambiguous regarding the position of the verb and the preverbal constituents, the paper applies methods for identifying diagnostic datasets which can be clearly distinguished in terms of structure and use. Two types of diagnostic non-verb-second orders are tested, namely verb-final clauses in which no verb movement applies, and verb-third clauses in which the verb as well as all preverbal categories occupy specified positions in the left periphery of the clause. The result is that diagnostic evidence for any of the datasets is sparse in native prose, and that especially diagnostic verb-third orders are not sufficiently distinguishable against their Latin originals. In addition, both diagnostic patterns interfere in use, suggesting that they represent less clearly differentiated, unproductive patterns, used for special stylistic purposes.

I provide an overview of the Tolerance Principle, its motivation, supporting evidence, and applications, with particular focus on how it can be used recursively to discover linguistic regularities of varying scopes. It corrects the misunderstandings in Enger’s recent article but the more important goal is to provide rigorously formulated predictions and quantitative data to the structural analysis of language.
Minnesang trifft Pijjut und Midrasch
Authors: Hon Jan K.
Published: November 2023

The essay examines the fourteenth-century Yiddish poem ›Yosef Ha-Tsadik‹ about Joseph and Potipharʼs wife. The poem, presented here in a new critical edition, is primarily based on Hebrew and Aramaic midrashic and liturgical sources but also incorporates elements derived from German courtly love poetry, mainly to express Potipharʼs wifeʼs advances toward Joseph. It can thus be read as a Jewish dialogue with Christian secular literary traditions. Drawing on a comparison with the Jewish pretexts – some of which are presented here for the first time in German translations – and a number of examples from Minnesang, the study analyzes the strategies of both participation in and (ironic) distancing from the Christian courtly discourse.

Published: November 2023

Objectives

Primary aldosteronism is the most common cause of endocrine hypertension and is associated with significant cardiovascular morbidities. The diagnostic workup depends on determinations of plasma aldosterone and renin which are highly variable and associated with false-positive and false-negative results. Quantification of aldosterone in 24 h urine may provide more reliable results, but the methodology is not well established. We aimed to establish an assay for urinary aldosterone and related steroids with suitability for clinical routine implementation.

Methods

Here, we report on the development and validation of a quantitative LC-MS/MS method for six urinary steroids: aldosterone, cortisol, 18-hydroxycorticosterone, 18-hydroxycortisol, 18-oxocortisol, tetrahydroaldosterone. After enzymatic deconjugation, total steroids were extracted using SepPak tC18 plates and quantified in positive electrospray ionization mode on a QTRAP 6500+ mass spectrometer.

Results

Excellent linearity was demonstrated with R2>0.998 for all analytes. Extraction recoveries were 89.8–98.4 % and intra- and inter-day coefficients of variations were <6.4 and <9.0 %, establishing superb precision. Patients with primary aldosteronism (n=10) had higher mean 24 h excretions of aldosterone-related metabolites than normotensive volunteers (n=20): 3.91 (95 % CI 2.27–5.55) vs. 1.92 (1.16–2.68) µmol/mol for aldosterone/creatinine, 2.57 (1.49–3.66) vs. 0.79 (0.48–1.10) µmol/mol for 18-hydroxycorticosterone/creatinine, 37.4 (13.59–61.2) vs. 11.61 (10.24–12.98) µmol/mol for 18-hydroxycortisol/creatinine, 1.56 (0.34–2.78) vs. 0.13 (0.09–0.17) µmol/mol for 18-oxocortisol/creatinine, and 21.5 (13.4–29.6) vs. 7.21 (4.88–9.54) µmol/mol for tetrahydroaldosterone/creatinine.

Conclusions

The reported assay is robust and suitable for routine clinical use. First results in patient samples, though promising, require clinical validation in a larger sample set.
Geochemical evaluation of the carbonaceous shale associated with the Permian Mikambeni Formation of the Tuli Basin for potential gas generation, South Africa
Authors: Akintola George Oluwole
Published: November 2023

The increasing demand for energy and global commitment to reduce CO2 emissions to mitigate climate change has spurred countries to pursue unconventional hydrocarbon generation for power production. The investigation of the carbonaceous shale from the Permian Mikambeni Formation of the Tuli Basin in South Africa aims to assess the potential for gas generation. The Rock-Eval 6 pyrolysis of the studied samples shows total organic carbon (TOC) content ranging from 10.10 to 37.61 wt%, indicating an excellent source rock quality since it exceeds the threshold limit of 5 wt%. The produced gas that emanated from the thermal breakup of remaining hydrocarbon (S2) ranged from 14.30 to 65.55 mg HC/g rock while the hydrogen index (HI) ranged from 56.55 to 198.22 mg/g TOC. The plot of the HI against T
max indicates the predominance of type-III kerogen, prone to gas generation. The thermal maturity parameters, T
max (430–466°C), and vitrinite reflectance, VRo (0.6–1.2), showed a matured organic material. The production index value (0.06) of the samples indicates a moderately mature source generating a biogenic gas. The carbon isotopic composition, δ
13C (−20.0 to −23.4‰), indicates a predominant influx of organic matter derived from a vascular higher plant. The studied samples showed relatively depleted values of oxygen isotopic composition δ
16O (14.1–18.8‰), suggesting a brackish water depositional environment. Additionally, the Ba concentration (303.15–331.27 ppm) exceeds the 200 ppm threshold for the marine environment, indicating a non-marine environment characterised by low marine paleo-productivity and high detrital influx. Based on the evaluation, the studied coaly-shale is found with a matured and type-III kerogen that is prone to gas generation in a fluvial, paleo-depositional environment.
Bayesian second-order sensitivity of longitudinal inferences to non-ignorability: an application to antidepressant clinical trial data
Authors: Momeni Roochi Elahe , Eftekhari Mahabadi Samaneh
Published: November 2023

Incomplete data is a prevalent complication in longitudinal studies due to individuals’ drop-out before intended completion time. Currently available methods via commercial software for analyzing incomplete longitudinal data at best rely on the ignorability of the drop-outs. If the underlying missing mechanism was non-ignorable, potential bias arises in the statistical inferences. To remove the bias when the drop-out is non-ignorable, joint complete-data and drop-out models have been proposed which involve computational difficulties and untestable assumptions. Since the critical ignorability assumption is unverifiable based on the observed part of the sample, some local sensitivity indices have been proposed in the literature. Specifically, Eftekhari Mahabadi (Second-order local sensitivity to non-ignorability in Bayesian inferences. Stat Med 2018;59:55–95) proposed a second-order local sensitivity tool for Bayesian analysis of cross-sectional studies and show its better performance for handling bias compared with the first-order ones. In this paper, we aim to extend this index for the Bayesian sensitivity analysis of normal longitudinal studies with drop-outs. The index is driven based on a selection model for the drop-out mechanism and a Bayesian linear mixed-effect complete-data model. The presented formulas are calculated using the posterior estimation and draws from the simpler ignorable model. The method is illustrated via some simulation studies and sensitivity analysis of a real antidepressant clinical trial data. Overall, the numerical analysis showed that when repeated outcomes are subject to missingness, regression coefficient estimates are nearly approximated well by a linear function in the neighbourhood of MAR model, but there are a considerable amount of second-order sensitivity for the error term and random effect variances in Bayesian linear mixed-effect model framework.

Authors: Zhang Xu , Wang Zhaoqian , Sun Simiao , Wang Yiming , Wang Zhi , Xie Hua
Published: November 2023

Biomass soybean oil-based polyol rigid polyurethane foam (RPUF) was modified and prepared by expandable graphite (EG). The effects of EG on the thermal stability and flame retardant properties of soybean oil-based polyol RPUFs were investigated by thermogravimetric analysis, pyrolysis kinetic analysis, conical calorimetry and flue gas toxicity analysis. The results showed that modified RPUF (RPUF-4) with EG content of 20 wt% had the highest initial and end temperatures, the highest activation energy E, the lowest Ds (17.6), and the highest light transmittance (73.6 %). At the same time, RPUF-4 had the lowest heat release rate (10.1 and 16.5 kW/m2), the lowest total heat release (1.5 and 2.1 MJ/m2), and the lowest average toxic gas emissions. The current study indicated that RPUF-4 had better thermal stability and flame retardant performance, which provided a useful reference for subsequent biomass flame retardant modified RPUFs.

Mitigating network adaptation and QoT prediction challenges in WDM networks
Authors: Garg Amit Kumar , Rai Saloni
Published: November 2023

The capacity and efficiency of optical communication networks have been completely transformed by wavelength division multiplexing (WDM) technology, which allows many wavelengths to be transmitted simultaneously over a single optical fibre. Conventional QoT prediction is based on analytical models that consider physical layer characteristics including dispersion, optical power and signal-to-noise ratio. But these models frequently oversimplify complex real-world situations, which reduces their accuracy for modern high-speed WDM networks. A data-driven solution is provided by machine learning(ML), which may boost the accuracy of QoT predictions by utilising real-time measurements, historical data and a variety of network situations. The creation of a ML-based framework for QoT prediction is investigated in the current research. This research proposes an effective ML-based routing computation model that uses a non-linear autoregressive recurrent neural network (ML-RCNA-RNN) to ensure QoT for every wavelength channel in high-capacity and high-speed WDM networks. Through simulations, more accurate QoT metrics, such as bit error rate (BER) 68.42 %, QoT prediction accuracy (Q-Factor) 5.9 %, network adaption time (ms) 48.3 %, latency (ms) 0.28 % and throughput (Gbps) 14.29 %, have been obtained compared to conventional QoT predictions. These results were obtained using Gaussian noise Python simulation (GNPy). As a result, the proposed framework that makes use of GNPy demonstrates that it substantially enhances optical communication networks’ performance and dependability. This facilitates the development of high-capacity, low-latency and reliable communication infrastructure, and makes it more adaptable and able to manage the complexity of high-speed WDM optical networks while preserving signal quality in the modern digital era.
Longitudinal assessment of auxological parameters, adult height outcome and its determinants in leuprolide-treated Indian girls with idiopathic central precocious puberty
Authors: Mondkar Shruti , Khadilkar Vaman , Yewale Sushil , Dange Nimisha , More Chidvilas , Khadilkar Anuradha
Published: November 2023

Objectives

To assess auxological parameters, adult height outcome and its determinants in Indian girls with idiopathic central precocious puberty (iCPP) treated with gonadotropin-releasing hormone analogues (GnRHa).

Methods

Retrospective study. Inclusion: data on girls with iCPP from initiation to stopping GnRHa (n=179). Exclusion: boys, peripheral, organic central precocity.

Results

Mean age of starting GnRHa: 8.2± 1.1 years, duration: 2.8± 1.2 years. 11.7 % had attained menarche at first presentation. The difference between bone (BA) and chronological (CA) ages reduced significantly from 2.6± 0.9 years (onset) to 1.6± 0.8 years (cessation). Weight, BMI Z-scores increased (p<0.01), height Z-scores decreased (0.8 vs. 0.6; p<0.01), predicted adult height (PAH) and Z-scores improved by 3.5 cm, 0.5 SDS following treatment (p<0.01). Overweight/obese girls (vs. normal BMI) were taller, with more advanced BA at starting (height Z-score: 0.7 vs. 1.0, BA-CA: 2.2 vs. 2.9 years), stopping (height Z-score: 0.5 vs. 0.9, BA–CA: 1.4 vs. 1.9 years) treatment, but showed no difference in PAH at starting, stopping treatment. Adult height data (n=58) revealed 1.9 cm gain above target height. Adult height Z-scores significantly exceeded target height Z-scores (p<0.01). Mean adult height (157.1± 5.8 cm) crossed PAH at starting treatment (155.9± 6.4 cm) but remained 1.6 cm lesser than PAH at cessation. Adult weight, BMI Z-scores (−0.2± 1.3, −0.1± 1.2) were significantly lower (p<0.01) than those at stopping GnRHa. Height gain adjusted for age at starting GnRHa correlated negatively with height, weight, BMI, Tanner-staging, BA, FSH, Estradiol at treatment onset, BA at cessation, and correlated positively with treatment duration.

Conclusions

GnRHa treatment in Indian girls with iCPP resulted in improved PAH, decelerated bone age advancement and growth velocity. Most girls achieved adult height within target range, surpassing PAH at treatment initiation. Lesser anthropometric, sexual, skeletal maturity, lower baseline FSH, estradiol, longer treatment duration, less advanced BA at stopping GnRHa may translate into better adult height outcomes.

Published: November 2023

Two-dimensional layered semiconductors have attracted intense interest in recent years. The van der Waals coupling between the layers tolerates stacking various materials and establishing heterostructures with new characteristics for a wide range of optoelectronic applications. The interlayer exciton dynamics at the interface within the heterostructure are vitally important for the performance of the photodetector and photovoltaic device. Here, a heterostructure comprising two-dimensional organic-inorganic Ruddlesden–Popper perovskites and transition metal dichalcogenide monolayer was fabricated and its ultrafast charge separation processes were systematically studied by using femtosecond time-resolved transient absorption spectroscopy. Significant hole and electron transfer processes in the ps and fs magnitude at the interface of the heterostructure were observed by tuning pump wavelengths of the pump-probe geometries. The results emphasize the realization of the exciton devices based on semiconductor heterostructures of two-dimensional perovskite and transition metal dichalcogenide.

Published: November 2023

Der Öffentliche Gesundheitsdienst (ÖGD) kann eine tragende Rolle im Umgang mit komplexen Krisen spielen und Veränderungsprozesse steuern. Aus Nachwuchsperspektive ist es besonders relevant, dass multiprofessionelle (Nachwuchs-)Fachkräfte synergetisch im ÖGD zusammenarbeiten. Darüber hinaus sollten interdisziplinäres Denken und Handeln strukturell verankert und gelebt werden. Der ÖGD der Zukunft kann dabei nur unter Einbezug der jungen Generationen attraktiv und wirkungsvoll aufgestellt werden.

Authors: Spähn Bianca Annika , Görig Tatiana , Diehl Katharina
Published: November 2023

Nicht-melanozytärer („weißer“) Hautkrebs ist die häufigste Krebsform in Deutschland. Als wichtigstes Präventionsmaß gilt der Schutz vor ultravioletter (UV-)Strahlung. Qualitative Daten zur älteren Bevölkerung zeigen zwar Defizite im aktuellen Sonnenschutzverhalten, jedoch scheint das Bewusstsein über Notwendigkeit von Sonnenschutz und Gefahren von UV-Strahlung über die Jahre gestiegen zu sein. Zur weiteren Aufklärung scheinen regionale und nationale Sonnenschutzstrategien auf verhaltens- und verhältnispräventiver Basis sinnvoll.

Authors: Tönnißen Kira , Krumm Stephan , Zielinski Wiebke , Süptitz Thomas
Published: November 2023

Die COVID-19-Pandemie hat den digitalen Nachholbedarf des Öffentlichen Gesundheitsdienstes (ÖGD) gezeigt: Daten konnten nur unzureichend – mit teils deutlichem Verzug – digital ausgetauscht werden. Zu oft musste die Kontaktnachverfolgung händisch erfolgen. In dieser Zeit wurde mit dem Pakt für den ÖGD ein einmaliges Programm beschlossen. Ein Schwerpunkt ist dabei die Digitalisierung. Dieser Beitrag beschreibt die Teile des Digitalisierungsanteils des Paktes für den ÖGD und deren Zusammenhänge.
Gesundheitsberichterstattung im ÖGD – Datenlage und Verbesserungsbedarf
Authors: Butler Jeffrey
Published: November 2023

Die kommunale Gesundheitsberichterstattung in Deutschland basiert primär auf der amtlichen Statistik. Daher fehlen hier zunehmend aussagekräftige Daten für immer anspruchsvollere Aufgaben, u.a. die Evaluation von gesundheitsförderlichen Maßnahmen, Präventionsberichterstattung und Pandemiebekämpfung. Einerseits fehlt eine gesetzliche Grundlage für notwendig aussagekräftigere Datenquellen, andererseits leidet die Gesundheitsberichterstattung unter der mangelnden Vergleichbarkeit von erhobenen Daten im föderalen deutschen Gesundheitssystem.

Published: November 2023

Design and aerodynamic performance analysis of a variable geometry axisymmetric inlet was carried out for tandem scheme turbine-based combined cycle (TBCC) propulsion system. The operation Mach number of the inlet was between 0 and 4. The design point was chosen as Mach number 4.0 in this paper. The determination of external and internal compression and the design method of annular to circle diffuser were illustrated. The inlet was unstart under Ma 3.0 without adjustment. Then, a variable scheme was designed to ensure self-start of the inlet and match the requirement of mass flow rate during the whole flight envelope. And four supports were used to fix the spike. According to the 3D numerical simulations, the total pressure recovery was 0.52 at Ma 4.0 at critical condition and the mass flow rate was consistent with the requirement at different flight Mach number.

Published: November 2023

This study investigates the turbulent flow field downstream of V-gutters using unsteady numerical modelling. An important domain of application of the vortex shedding induced by the V-gutters is the flame stabilization in high speed combustion systems which find extensive applications in aerospace engineering. In view of this, the present study analyses the impact of the V-gutter geometry, as characterized by the included angle, on inducing vortex motion in the wake. Transient simulations are carried out for three values of the semi-span angle, α = 30°, 45° and 60°. Based on the analysis of the saddle point and the vortex shedding frequency, the study shows that an increase in span angle within this range, favours the effectiveness of the method in flame stabilization. Though the simulations are done for cold flow, the dominant mechanism of vortex shedding is adequately addressed in the analysis.
Luke 9:57–62: Ὁδός to Marcion’s God?
Authors: Walters Patricia
Published: November 2023

The first few centuries of the Common Era saw great theological fluidity in emerging Christian doctrine. A figure looming large in many early controversies is Marcion of Pontus. Not considered truly gnostic by modern scholars, Marcion fueled the ire of early Church Fathers—Justin Martyr, Irenaeus, Tertullian, and others—by spreading his apparently biblically-based, ditheistic theology of a superior Unknown Good God and an inferior Just Creator God. Additionally, Marcion’s gospel, generally considered a version of canonical Luke, witnesses the three Jesus sayings in Luke 9:57–62 (cf. Tertullian, Adversus Marcionem 4,23,9–11; Clement of Alexandria, Stromata 3,4,25). This article examines these sayings—in light of both ancient and modern commentary—as representing a collective theological way or ὁδός to ideate Marcion’s Unknown Good God. Today Marcion’s voice is faint, but in ancient Christianity it was exceedingly strong. This article attempts to find a hint of its former strength.
Historical Ruptures in Eusebius’ History of the Jerusalem Church
Authors: Livneh Yonatan
Published: November 2023

Eusebius of Caesarea includes in his Historia ecclesiastica several episodes regarding the Jerusalem church, in which he emphasizes periods of rupture in the history of this community in the aftermath of the Judean wars. The current paper explores this material and, first, clarifies Eusebius’ pioneering role in the construction of a coherent history of the Jerusalem church, and, second, explains his focus on breaks in this history, in spite of the difficulties such ruptures pose for his conceptions of divine providence and apostolic succession. In the first part, after surveing Eusebius’ possible sources for the history of the Jerusalem church (Hegesipus, Ariston of Pella, Julius Africanus), the paper concludes that it was Eusebius who first composed a coherent history of this church, a narrative mostly based on his independent research in Jerusalem. The second part of the paper presents Eusebius’ concern, already in the beginning of his episcopacy, with the Jerusalem bishopric’s celebration of its succession from James and the apostolic fathers, in its claim for superiority in the province. For Eusebius, so the paper claims, destabilizing the conception of direct apostolic succession in the Jerusalem church could somewhat restrain these local aspirations, and thus support his own position as metropolitan bishop in Palestine.
Hippocampal Functions Modulate Transfer-Appropriate Cortical Representations Supporting Subsequent Memory

Published: November 2023

The hippocampus plays a central role as a coordinate system or index of information stored in neocortical loci. Nonetheless, it remains unclear how hippocampal processes integrate with cortical information to facilitate successful memory encoding. Thus, the goal of the current study was to identify specific hippocampalcortical interactions that support object encoding. We collected fMRI data while 19 human participants (7 female and 12 male) encoded images of real-world objects and tested their memory for object concepts and image exemplars (i.e., conceptual and perceptual memory). Representational similarity analysis revealed robust representations of visual and semantic information in canonical visual (e.g., occipital cortex) and semantic (e.g., angular gyrus) regions in the cortex, but not in the hippocampus. Critically, hippocampal functions modulated the mnemonic impact of cortical representations that are most pertinent to future memory demands, or
transfer-appropriate representations
. Subsequent
perceptual memory
was best predicted by the strength of
visual representations
in ventromedial occipital cortex in coordination with hippocampal activity and pattern information during encoding. In parallel, subsequent
conceptual memory
was best predicted by the strength of
semantic representations
in left inferior frontal gyrus and angular gyrus in coordination with either hippocampal activity or semantic representational strength during encoding. We found no evidence for
transfer-incongruent
hippocampalcortical interactions supporting subsequent memory (i.e., no hippocampal interactions with cortical visual/semantic representations supported conceptual/perceptual memory). Collectively, these results suggest that diverse hippocampal functions flexibly modulate cortical representations of object properties to satisfy distinct future memory demands.

Significance Statement
The hippocampus is theorized to index pieces of information stored throughout the cortex to support episodic memory. Yet how hippocampal processes integrate with cortical representation of stimulus information remains unclear. Using fMRI, we examined various forms of hippocampalcortical interactions during object encoding in relation to subsequent performance on conceptual and perceptual memory tests. Our results revealed novel hippocampalcortical interactions that utilize semantic and visual representations in transfer-appropriate manners: conceptual memory supported by hippocampal modulation of frontoparietal semantic representations, and perceptual memory supported by hippocampal modulation of occipital visual representations. These findings provide important insights into the neural mechanisms underlying the formation of information-rich episodic memory and underscore the value of studying the flexible interplay between brain regions for complex cognition.
