Abstract. New particle formation (NPF) is a major source of aerosol particles and cloud condensation nuclei in the troposphere, playing an important role in both air quality and climate. Frequent NPF events have been observed in heavily polluted urban environments, contributing to the aerosol number concentration by a significant amount. The Po Valley region in northern Italy has been characterized as a hotspot for high aerosol loadings and frequent NPF events in southern Europe. However, the mechanisms of NPF and growth in this region are not completely understood. In this study, we conducted a continuous 2-month measurement campaign with state-of-the-art instruments to elucidate the NPF and growth mechanisms in northern Italy. Our results demonstrate that frequent NPF events (66 % of all days during the measurement campaign) are primarily driven by abundant sulfuric acid (8.5×106 cm−3) and basic molecules in this area. In contrast, oxygenated organic molecules from the atmospheric oxidation of volatile organic compounds (VOCs) appear to play a minor role in the initial cluster formation but contribute significantly to the consecutive growth process. Regarding alkaline molecules, amines are insufficient to stabilize all sulfuric acid clusters in the Po Valley. Ion cluster measurements and kinetic models suggest that ammonia (10 ppb) must therefore also play a role in the nucleation process. Generally, the high formation rates of sub-2 nm particles (87 cm−3 s−1) and nucleation-mode growth rates (5.1 nm h−1) as well as the relatively low condensational sink (8.9×10-3 s−1) will result in a high survival probability for newly formed particles, making NPF crucial for the springtime aerosol number budget. Our results also indicate that reducing key pollutants, such as SO2, amine and NH3, could help to substantially decrease the particle number concentrations in the Po Valley region.

Abstract. The three most abundant stable isotopes of Silicon (Si), 28Si, 29Si, and 30Si, all occur in plants. Isotope studies are a potential tool to explore uptake and function of plant Si, and it is a developing field. However, there is a lack of studies from natural environments, and species from the African continent, and all plant parts including reproductive structures. In this study, naturally grown papyrus plants were sampled from the Okavango Delta and divided into five organs, i.e. umbel, culm, scales, rhizome, and roots. Samples were analysed for TN, TOC, BSi, TP concentrations, and for Si isotopes. Each organ of papyrus is represented by two samples, one from juvenile tissue and one mature (apart from the roots where age is difficult to determine). The study confirms that papyrus is a high Si-accumulating species, with BSi ranging from 0.88 % in rhizomes to 6.61 % in roots. High Si precipitation in the roots leads to an enrichment in heavy Si isotopes in the residual mobile Si pool, as light Si isotopes precipitate in phytoliths in the roots, even though in this study phytoliths were identified for all organs except for roots. In papyrus, shoot organs gradually become enriched in heavy Si isotopes along the transpiration stream, with an increase in heavy isotopes from rhizomes to scales, culm, and umbel, same pattern that has been observed for other plants in literature.
Combining crosshole and reflection borehole-GPR for imaging controlled freezing in shallow aquifers

Published: February 2024

Abstract. During test operation of a geological latent heat storage system as a potential option in the context of heat supply for heating and cooling demands a part of a shallow quaternary glacial aquifer at the “TestUM” test site is frozen. To evaluate the current thermal state in the subsurface the dimension of the frozen volume has to be known. With the target being too deep for high resolution imaging from the surface, the use of borehole Ground-Penetrating-Radar (GPR) is assessed. For imaging and monitoring of a vertical freeze-thaw boundary, crosshole zero-offset and reflection measurements are applied. The freezing can be imaged in ZOP, but determination of ice body size is ambiguous, because of lacking velocity information in the frozen sediment. Reflection measurements are able to image the position of the freezing boundary with an accuracy determined through repeated measurements of ±0.1 m, relying on the velocity information from ZOP. We found, that the complementary use of ZOP and reflection measurements make for a fast and simple method, to image freezing in geological latent heat storage systems. Problematic is the presence of superimposed reflections from other observation wells and low signal-to-noise ratio. The use in multiple observation wells allows for an estimation of ice body size. A velocity model derived from zero-offset profiles (ZOP) enabled to extrapolate geological information from direct-push based logging and sediment cores to a 3D-subsurface model.
Stable and unstable fall motions of plate-like ice crystal analogues

Published: February 2024

Abstract. The orientation of ice crystals affects their microphysical behaviour, growth, and precipitation. Orientation also affects interaction with electromagnetic radiation, and through this, influences remote sensing signals, in-situ observations, and optical effects. Fall behaviours of a variety of 3D-printed plate-like ice crystal analogues in a tank of water-glycerine mixture are observed with multi-view cameras and digitally reconstructed to simulate falling of ice crystals in the atmosphere. Four main falling regimes were observed: stable, zigzag, transitional, and spiralling. Stable motion is characterised by no resolvable fluctuations in velocity or orientation, with the maximum dimension oriented horizontally. The zigzagging regime is characterised by a back-and-forth swing, corresponding to a time series of inclination angle approximated by a rectified sine wave. In the spiralling regime, analogues consistently incline at an angle between 7 and 28 degrees, depending on particle shape. Transitional behaviour exhibits motion in between spiral and zigzag, similar to that of a falling spherical pendulum. The inclination angles that unstable planar ice crystals make with the horizontal plane are found to have a non-zero mode. This observed behaviour does not fit the Gaussian model of inclination angle that is common in the literature. The typical Reynolds number when oscillations start is strongly dependent on shape: solid hexagonal plates begin to oscillate at Re = 237, whereas several dendritic shapes remain stable throughout all experiments, even at Re > 1000.

Published: February 2024

Abstract. With global warming, forests are facing an increased exposure to compound soil and atmospheric drought (CSAD) events, characterized by low soil water content (SWC) and high vapor pressure deficit (VPD). Such CSAD events trigger responses in both ecosystem and forest floor CO2 fluxes, of which we know little about. In this study, we used multi-year daily and daytime above canopy (18 years; 2005–2022) and daily forest floor (five years; 2018–2022) eddy-covariance CO2 fluxes of a Swiss forest site (montane mixed deciduous forest; CH-Lae). The objectives were (1) to characterize CSAD events at CH-Lae; (2) to quantify the impact of CSAD events on ecosystem and forest floor daily CO2 fluxes; and (3) to identify the major drivers and their temporal contributions to changing ecosystem and forest floor CO2 fluxes during CSAD events and CSAD growing seasons. Our results showed that the growing seasons of 2015, 2018, and 2022, were the top three driest (referred as CSAD years) at CH-Lae since 2005, with similar intensity and duration of the respective CSAD events, but considerably different pre-drought conditions. The CSAD events reduced daily mean net ecosystem productivity (NEP) in all three CSAD years, with highest reduction during 2022 (30 % decrease). This reduction in daily mean NEP was largely due to decreased gross primary productivity (GPP; >15 % decrease) rather than increased ecosystem respiration (Reco) during CSAD events. Furthermore, forest floor respiration (Rff) decreased during the CSAD events in 2018 and 2022 (no measurements in 2015), with a larger reduction in 2022 (>40 %) than in 2018 (<25 %) compared to the long-term mean (2019–2021). Using data-driven machine learning methods, we identified the major drivers of NEP and Rff during CSAD events. While daytime mean NEP during 2015 and 2018 CSAD events was limited by VPD or SWC, respectively, daytime mean NEP during the 2022 CSAD event was strongly limited by both SWC and VPD. Air temperature always had always negative effects, net radiation positive effects on daytime mean NEP during all CSAD events. Daily mean Rff during the 2018 CSAD event was driven by soil temperature and SWC, but severely limited by SWC during the 2022 CSAD event. We found that a multi-layer analysis of CO2 fluxes in forests is necessary to better understand forest responses to CSAD events, particularly if the first signs we saw of acclimation to such CSAD events for our forest are found elsewhere as well. We conclude that such events have multiple drivers with different temporal contributions, making prediction of site-specific CSADs and forest long-term responses to such conditions more challenging.
Optimization strategy for flexible barrier structures: investigation and back analysis of a rockfall disaster case in southwestern China

Published: February 2024

Abstract. Field investigations and back analyses were conducted on a rockfall hazard. The flexible barrier protection system constructed along the roadside was damaged by the rockfall impact and lost its mitigation ability. Vital physical characteristics such as rockfall trajectory and kinetic energy were presumed based on the data from the aerial survey and the slope digital model. A numerical model, including slope, rockfalls, and flexible barrier, was created and thus the impacting process was reproduced. It demonstrates that the impact kinetic energy of the rockfall is only around 40 % of its design protection energy. The improper connections of members are the leading causes of damage, which prevent the flexible barrier from producing significant deformation and reduce its capacity to absorb impact force. The damage can be avoided by changing the connections of the members to improve the ability of the nets and ropes to slide and deform. The calculation results indicate that the impact resistance of the optimized model is 3 times better than the actual project. The findings can be used as a guide when designing a flexible protection system that performs better.
Teaching Resilient Mindsets: Developing a Model and an Active Learning Workshop for First-Year College Students
Authors: Jalalian-Chursky Krystle , Tausen Brittany M.
Published: February 2024

This practice report describes the development of a compensatory educational model to introduce first-year college students to resilient mindsets. The Teaching Resilient Mindsets Model emphasized (1) realistic expectations, (2) an “always learning” mindset, and (3) being prepared for challenges before they arise. After development, the Teaching Resilient Mindsets Model was delivered during freshman orientation via an active learning workshop. At the resilience workshop students practiced core components of the model and built a “resilience toolbox” to take with them as a resource for their transition to college. Experiential evidence of student engagement alongside quantitative and qualitative reflections from students emphasized the efficacy of the workshop and the opportunities it provided to practice resilient mindsets and prepare for potential challenges. The practice report ends with personal reflections on the (un)expected impacts of the workshop as well as opportunities for improvement.
Imaginarios distópicos e imaginarios ecosociales: prácticas artísticas al inicio de la pandemia en Chile y España
Authors: Villalobos Paloma
Published: February 2024

Este artículo realiza una revisión de la práctica artística y de ciertas narrativas visuales desarrolladas durante el ­período de inicio de la pandemia de Covid-19 (marzo a mayo 2020) concentrándose en proyectos realizados en Chile y España. Mediante una selección de obras producidas durante el confinamiento y la cuarentena, este estudio propone una lectura comparativa entre países con el objetivo de encontrar afinidades y diferencias en las producciones artísticas, analizando cómo desde cada contexto y bajo una mirada particular socioeconómica y política, surgen representaciones tan documentales como metafóricas. Nos focalizaremos en dos perspectivas: por un lado, obras que apelan a un imaginario distópico que sugiere cómo las sociedades, debido a la parálisis global, experimentaron una realidad anómala y amenazante que parecía ficticia; por otro, obras que desarrollan un imaginario ecosocial que esboza una sensibilidad sobre la crisis medioambiental y el actual desequilibrio entre naturaleza/humano. Desde ambas perspectivas se examina cómo las/los artistas, en el encierro, articularon dispositivos reflexivos que retrataron la inquietud ante un porvenir desconocido y la activación de la noción de fragilidad, logrando visibilizar procesos desastrosos tan sociales como ecológicos que ya venían desarrollándose y que parecieron agudizarse con la llegada de la pandemia.

The purpose of this study is T.R. It is an evaluation of the awareness of primary school students about waste management and recycling as a result of the implementation of the 'Zero Waste Project' carried out by the Ministry of Environment, Urbanization and Climate Change. The research was conducted with qualitative method. The study group of the research consists of 28 teachers, 3 school administrators and 37 parents selected by simple random sampling method, teaching 883 students attending a primary school in Etimesgut district of Ankara. In the research, the interview form was used as a data collection tool. In this interview form, after the questions about the participant's status relative to the student and the grade level, there are questions about the project and the awareness of waste management and recycling that has developed in the students. The data were evaluated by the content review method. As a result of the research, it was determined that the Zero Waste Project created awareness among students about waste management and recycling and resulted in behavioral changes. It has been revealed that waste battery collection and recycling exhibition activities contributed the most to the formation of this awareness. Students' sensitivity to waste is highest in the form of batteries and lowest in the form of wood waste. It is recommended to increase the number of projects aimed at increasing and disseminating activities in order to increase students' awareness of waste management and recycling and to maximize their sensitivity in all types of waste.

Published: February 2024

En este trabajo se estudia la dinámica de los estados vórtices, la densidad de electrones superconductores y la inducción magnética en una muestra superconductora con geometría cuadrada de tipo II, utilizando las ecuaciones bidimensionales de Ginzburg Landau no lineal dependiente del tiempo (TDGL, Time dependen Gisburn and Landau equation) que se resuelven usando el método de los elementos finitos, implementado en el Software COMSOL Multiphysics. Para este fin normalizamos las ecuaciones de Ginzburg Landau con condiciones de contorno de Neumann y condiciones iniciales en el estado Meissner, para diferentes intensidades de campo magnético aplicado y en dirección perpendicular a la muestra superconductora. Los resultados muestran que, al aplicar diferentes intensidades de campo magnético sobre la muestra, la barrera de energía en la frontera disminuye permitiendo el ingreso del flujo magnético cuantizado, posibilitando observar: los estados vórtice, la supresión de la densidad de electrones superconductores y el incremento de la inducción magnética en la muestra superconductora. La penetración del flujo magnético cuantizado depende del tamaño de la muestra, el tiempo y la intensidad del campo magnético aplicado.

Published: February 2024

La alta prevalencia de enfermedades no transmisibles, como enfermedades cardiovasculares, diabetes, cáncer y desnutrición a nivel global, junto con la creciente demanda de productos naturales con mínimos efectos secundarios y amigables con el medio ambiente, ha estimulado la investigación en el campo de los nutracéuticos y alimentos funcionales. Este impulso se ha fortalecido gracias al descubrimiento de diversos compuestos fitoquímicos con un gran potencial industrial, siendo un ejemplo destacado el maíz morado.

El Zea mays L. (variedad morada) es un cereal cultivado en Perú desde épocas prehispánicas, utilizado principalmente en la elaboración de chicha y mazamorra morada. En la actualidad, se producen extractos acuosos atomizados para comercializarlos como colorantes naturales en Sudamérica, Asia y Europa. Además de su aplicación culinaria, el maíz morado contiene niveles elevados de antocianinas, responsables de su color morado, y ha demostrado tener efectos protectores en modelos preclínicos de enfermedades crónicas como ateroesclerosis, hipertensión arterial, artritis y diabetes mellitus, gracias a las propiedades antioxidantes de las antocianinas.

El cultivo de maíz morado tiene un gran valor en los mercados nacional e internacional debido a su destacado perfil nutricional y su contenido de compuestos bioactivos, como antocianinas y compuestos fenólicos. Estudios han identificado la presencia de ácidos fenólicos como el ácido vanílico, ácido cafeico y ácido ferúlico, así como flavonoides como hesperedina, quercetina y kaempferol.

Intimations of a Lyricism sans Subject
Authors: Obrigewitsch Alex
Published: February 2024

The lyric is a form or genre of poetry often intimately related to subjectivity. But is a lyricism divested of the subject possible? By examining the philosophical refl ections of Philippe Lacoue-Labarthe upon lyricism, poetry, and their relation to subjectivity, this article explicates how an impersonal lyricism is not only possible, but perhaps necessary. If we wish to do justice to the phrasing or saying of poetic language, then we must endeavour to think the displacement of the subject in and by the very language that the poem expresses. Following Lacoue-Labarthe, this article explores the paradoxical turn of lyricism—that it is bound to the subject, but not to its personal expression; rather, to its disappearance, its displacement, in the expression of language itself. By tracing a sketch of Lacoue-Labarthe’s poetics, relating this thought to the lyrical theories of Hamburger and Culler, and providing a brief explication of one of Lacoue-Labarthe’s “poetic” writings, lyricism is shown to be the testament to the disappearance of the subject, the remainder of a disappearance already passed insofar as the poem remains. What remains is that the lyrical subject would be no “subject” at all—only language itself, intimating its own diction.

Illicit use of narcotic drugs and psychotropic substances is becoming a major problem in India. People from different age groups are consuming illicit drugs and experiencing dependence and addiction problem. Cannabis is one such drug, a flowering plant having psychoactive nature due to presence of different cannabinoids. Its analysis in stepwise manner is essential for recognition. The forensic analysis is performed by using various techniques such as microscopy, chromatography, spectroscopy, etc. Currently, the forensic examination of cannabis is more focused on qualitative analysis in preliminary examination though quantitative analysis is also important which can play a major role in investigation. The present study focuses on analysis of cannabis sativa by color test, thin layer chromatography, UV visible spectroscopy and IR spectroscopy. Estimation of limit of detection for all methods for cannabis is the prime goal. According to the study, LoD for Fast Blue B and Duquenois Levine test is found to be 0.001 mg/mL and 0.125 mg/mL, respectively while LoD for thin layer chromatography and UV visible spectrophotometry is observed to be 0.5 mg/mL. and 0.10 mg/mL, respectively. The study helps to determine the sensitivity of all above mentioned techniques for cannabis examination along with its functional group identification.

The Effect of Accrual Earnings Management and Real Earnings Management on Environmental, Social, and Governance (ESG) Reporting Performance
Authors: Fadhilah Alfiyyah Nuur , Suranta Eddy
Published: February 2024

This research aims to offer empirical insights into variations in earnings management within companies categorized in the Environmental, Social, and Governance (ESG) score ranking, and seeks to establish a correlation between earnings management practices and Environmental, Social, and Governance (ESG) performance. The study scrutinizes accrual earnings management alongside real earnings management. The Environmental, Social, and Governance (ESG) score ranking comprises four categories: low, medium, high, and severe. Accrual earnings management is gauged through the modified Jones model, while real earnings management is assessed using three proxies ABNCFO, ABNPROD, and ABNDISC. The research focuses on manufacturing companies possessing Environmental, Social, and Governance (ESG) scores and adopts a purposive sampling approach. The outcomes reveal distinctions between ABNCFO and ABNPROD real earnings management in the severe and low ESG rating groups, whereas no differences exist in accrual earnings management and ABNPROD real earnings management. Additionally, the study establishes that ABNCFO and ABNDISC real earnings management significantly influence Environmental, Social, and Governance (ESG) performance positively. Conversely, accrual earnings management shows no adverse impact on Environmental, Social, and Governance (ESG) performance, and ABNPROD real earnings management exhibits a positive albeit insignificant effect on Environmental, Social, and Governance (ESG) performance.  The practical implication of this research is that when the company has a high ESG score which reflects the uncertainty of the company's future operations, the company tends to carry out real earnings management in the form of abnormal cash flow operations (ABNCFO) and abnormal discretionary expenses (ABNDISC).
Economic Growth Model with Regional Expenditure as a Moderation Variable: Scale in Berau Regency
Authors: Roy Juliansyah , Rochaida Eny , Suharto Rahcmad Budi
Published: February 2024

The motivation of this paper aims to investigate the relationship between local taxes, DAU, and DBH on the economic growth of Berau Regency. Apart from that, the paper also identifies the relationship between regional taxes, DAU, and DBH on economic growth which interacts with regional expenditure in Berau Regency. Government revenue is an important instrument for regions to foster economic growth. At the same time, government spending is used as a fiscal support to review the degree of budget absorption. With surplus revenue performance, it will generate financing which also plays a vital function in boosting economic growth. Secondary data for 2013–2022 was collected from government budget documents. Then, the data is tabulated using a time-series linear regression model with moderating variables. The statistical output finds that regional taxes and DBH have a negative effect on economic growth. However, DAU actually has a positive effect on economic growth. Uniquely, the interaction between regional taxes and DAU which is moderated by regional spending has a positive influence on economic growth. Then, regional spending plays a negative role in the relationship between DBH and economic growth. Future implications of considering practical regulations that do not only depend on income from the DAU side, but must focus on the existence of regional taxes in Berau Regency. By optimizing regional taxes, it also allows for a large fiscal gap in terms of regional spending. Financing the development of Berau Regency requires adequate expenditure allocation.

Published: February 2024

This study employs a quantitative approach to explore the intricate interplay among Sustainability Reports, Financial Performance (measured by Return on Assets - ROA), and Firm Value (quantified by Tobin's Q) in Indonesia's dynamic mining industry. Employing purposive sampling, data from 75 samples encompassing 25 mining businesses listed on the Indonesia Stock Exchange (IDX) is examined over the 2020-2022 period. Utilizing statistical analysis, the study employs the Partial Least Squares (PLS) data processing application for partial regression analysis. The findings highlight a substantial and favorable impact of Sustainability Reports on Firm Value, underscoring the growing acknowledgment within Indonesian mining firms of the pivotal role played by both financial and non-financial disclosures. Intriguingly, the study uncovers that Financial Performance, as gauged by ROA, lacks a discernible influence on Firm Value. This nuanced insight suggests a shifting landscape where stakeholders increasingly prioritize comprehensive reporting beyond conventional financial metrics. The research sheds light on the evolving nature of the Indonesian mining sector, emphasizing companies' recognition of the significance of transparent reporting practices. These revelations align with global sustainable development goals, emphasizing the central role played by mining companies in advancing these objectives. In navigating this complex dynamic, the study underscores the crucial role of Sustainability Reports in shaping perceptions and values of mining firms in Indonesia.

The Effect of Concentrated Ownership on Tax Avoidance: CSR Mediates or Moderates

Published: February 2024

This study seeks to empirically demonstrate the relationship between concentrated ownership and tax avoidance, exploring the potential role of Corporate Social Responsibility (CSR) as either a mediating or moderating variable. From the aim of this research, the formulation of the problem in this research is whether concentrated ownership has an effect on tax avoidance and this research wants to further prove whether CSR is more appropriate to use as a mediating or moderating variable in explaining the relationship between concentrated ownership and tax avoidance. The research focuses on a selection of manufacturing firms that uphold CSR values during the period from 2019 to 2021, employing purposive sampling as the method for sample selection. Concentrated ownership is defined as ownership exceeding 50%, while tax avoidance is measured using the Effective Tax Rate (ETR). The results prove that concentrated ownership encourages management to conduct tax avoidance as an effort to obtain additional capital for the firm's investment needs so that companies tend to shift current taxes to future taxes. This research proves the existence of agency problems where concentrated ownership expropriates minority interests. CSR functions as a moderating factor in the correlation between concentrated ownership and tax avoidance. It serves to diminish managerial endeavors in evading taxes by establishing corporate legitimacy. With better implementation of CSR, it is hoped that this will not be a motivation for companies to avoid taxes when companies are dominated by concentrated ownership and investors prefer to invest in companies that have concentrated shares.
COULD PAUL TAYLOR’S BIOCENTRISM BE INTERPRETED AS A RAWLSIAN THEORY OF JUSTICE?
Authors: STOENESCU Constantin
Published: February 2024

In his „A Theory of Justice” Rawls accepts that „a conception of justice is but one part of a moral view”, that „it is wrong to be cruel to animals and the destruction of a whole species can be a great evil”, and that there are moral duties regarding animals, species and nature, but „they are outside the scope of the theory of justice, and it does not seem possible to extend the contract doctrine so as to include them in a natural way”. However, Rawls mention a way to find an answer to this challange: „A correct conception of our relations to animals and to nature would seem to depend upon a theory of the natural order and our place in it. One of the tasks of metaphysics is to work out a view of the world which is suited for this purpose;it should identify and systematize the truths decisive for these questions.” (Rawls, „A Theory of Justice”, 1999, p. 512). My aim in this paper is to argue that Environmental Ethics tried to offer exactly this requested theory of natural order so that it become possible to talk in terms of justice about an extended moral community, the so-called biotic community or community of life. I claim that biocentrism is a theory which is able to fulfill this task. Paul W. Taylor, in his „The Ethics of Respect for Nature” (1981) develops a theory based on the concepts of respect for nature, good of a being and inherent worth. If Rawls (See his „Justice as Fairness”, Philosophical Review, 1958, 67, p. 183) describes the rules of the duties of human morality (fidelity, gratitude, honesty and fidelity) as „forms of conduct in which recognition of others as persons is manifested”, Taylor considers that „the rules of duty governing our treatment of the natural world and its inhabitants are forms of conduct in which the attitude of respect for nature is manifested.” (1981) I will argue that the extension of moral community is possible using Rawls’ conceptual framework. Therefore, a new theory of natural order can be derived step by step so as the contract doctrine will be extended without any prejudices to Rawlsian initial presuppositions. My aim is to offer a reconstruction of this extension. Then I shall return to Taylor and his biocentrism.
Yoshihiro Tatsumi’s Influence on Adrian Tomine’s Short-Story Cycle Killing and Dying
Authors: Edenfield Olivia Carr
Published: February 2024

Adrian Tomine’s Killing and Dying (2015) is one of the most celebrated graphic novels of the twenty-first century—although that genre designation is misleading inasmuch as the book is actually a short-story cycle composed of six seemingly autonomous short stories linked together by shared topics and motifs. This essay examines how Tomine achieves overall narrative unity despite the individual stories’ heterogeneous settings, plots, and characters. In particular, this analysis examines how Tomine employs the theme of “striving and failing” to link the texts: each entry is united by a character’s need to connect, to be seen, to be understood. Protagonists suffer from worries and fears they are unable to articulate, their anxieties rarely fully framed on the page. Additionally, this reading of Killing and Dying explores how Tomine sublimates the influence of 1960s manga artist Yoshihiro Tatsumi (1935–2015), whose work Tomine helped bring to English-speaking audiences after decades of neglect, in organizing the cycle.
Interpreting (Mostly) Hemingway’s in our time Vignettes
Authors: Brenner Gerry
Published: February 2024

Performance theory liberates readers from consuming texts as products of author- or culture- or tradition-based packaging. By destabilizing conventional norms of how texts should be or are taught to be read, it opens fresh and contradictory ways of “understanding” and imagining their narrator. Given Ezra Pound’s poetic “impersonations” and his influence on young Ernest Hemingway’s writing, the vignettes of Hemingway’s first collection, in our time, offer ample ways to be performed.
Characteristically Fitzgerald: Propriety in Morphing Cultural Contexts in F. Scott Fitzgerald’s “Thank You for the Light”
Authors: Senn Farrah R.
Published: February 2024

F. Scott Fitzgerald’s “Thank You for the Light” seems atypical of the author at first glance compared to the larger body of his work. Discovered by his grandchildren, it appeared in The New Yorker in 2012, the same magazine that rejected it when submitted by Fitzgerald in 1936. This short story about Mrs. Hanson, a forty-year-old widowed corset saleswoman who just wants to smoke a cigarette, has baffled modern critics as much as it did the editors who initially denied its publication. However, a closer read and consideration of the author’s contemporary cultural and personal context reveals that the trademarks of Fitzgerald’s 1920s flapper stories are just as evident in this work. Using a social contract theory-based framework positing that time and place are inseparable mediators in determining propriety, this article focuses primarily on how the evolution of cultural attitudes toward smoking is expressed in this work, but also discusses other contemporary references, connections to the author’s personal experiences, and comparisons to his other works. These connections and comparisons illustrate how in this piece from his late career, though he was plagued by personal issues, professional disappointments, and poor physical health, Fitzgerald is still the ever-autobiographical, morally questioning chronicler of the times, but times are just different: Mrs. Hanson’s uncertainty is simply a result of the uncertain times in which she and Fitzgerald were living.
