При добавлении тартрат-, оксалат- и цитрат-анионов в ходе синтеза металлакраунов меди 12-МС-4 на основе β-аланингидроксиматных лигандов выделены, соответственно, димерный комплекс Cu10(b-alaha)8(tartrate)2*10H2O (1) и два одномерных координационных полимера состава Cu5(b-alaha)4Cu(oxalate)2*8H2O (2) и Cu10(b-alaha)8Cu(citrate)2*19H2O (3). По данным РСА, для 2 и 3 в присутствии оксалатных и цитратных анионов происходит образование бесконечных цепочек в кристалле, содержащих чередующиеся молекулы катионного металлакрауна меди 12-МС-4 и комплексного поликарбоксилатного купрат-аниона. При этом расстояние между молекулами металлакрауна в кристалле определяется природой добавленного в реакционную смесь поликарбоксилатного аниона. В отличие от оксалат- и цитрат-анионов, гостевой двухосновный тартрат-анион не вызывает образования бесконечных одномерных цепочек в кристалле. В этом случае образуется димерный комплекс 1, для которого реализуются короткие контакты Cu-O между соседними металламакроциклами.
In plain sight - Engineers, Engineering and Ethics
Authors: Mitchell Dervilla
Published: April 2024

Engineering is everywhere and underpins so much of what we expect and need in our daily lives, yet engineers are not generally prominent in society and are perhaps not valued for the role they play.

As Dervilla reaches the later stages of her career in Arup she is reflecting on what is it to be an Engineer, what is Engineering and how do we behave ethically than enables our profession (in the widest sense) to be valued and have a strong reputation in the public eye.

She is considering the changing perceptions of engineers, with a particular focus on the changes she has seen during her career; whether they be the way we work, the tools we use or the diversity in our workplaces.

She will highlight the challenges and opportunities we face and look in particular at some of the ethical dilemmas as we need to navigate in a world where climate change remains a challenge and increasing use of technology and data requires us to adapt and change at an ever-increasing pace.
Rehabilitation of the Outeiro Bridge with emergency strengthening of the superstructure damaged by barges impact
Authors: de Oliveira Almeida Pedro Afonso , Almeida Silveira Adler , Martins Pamplona Leila , da Paixão Silva Evelly Beatriz
Published: April 2024

The collapse of one of the supports of the central section of the bridge compromised the overall stability of the deck, leading to the immediate shutdown of its operation on January 16, 2022. Therefore, the occurrence of the collapse of the AP4 support after 37 years of operation led to the immediate isolation of the population of Outeiro Island, which today has 80,000 inhabitants, who use the bridge daily, with a volume of motor vehicles in the order of 4,500 per day. Therefore, as a premise, both the emergency strengthening and retrofitting of the Outeiro I Bridge were carried out with the partial operation. Considered an urban bridge over the Maguary Canal where there are large shipyards and docking ports for barges convoy that transit on the Belém-Manaus waterway route, the solution considered the duplication of the navigation channel with the construction of the cable-stayed bridge on the central section, making it safe for both heavy vehicle traffic and navigation with 2 navigation channels with a width of 80m and 100m and 12m height.
Design and Construction of an Arch Bridge over Railway Line no. 132 in Poland using BIM Tools
Authors: Majka Michal , Stempin Patryk , Wisniewski Dawid
Published: April 2024

This paper presents the design and construction for the new road-over-rail bridge in Dabrowa, Poland. The bridge is a replacement to the existing structure which significantly deteriorated over the years since the 1960s when it was built. Before the decision was taken to replace the existing bridge, a comprehensive study had been undertaken to investigate the possibilities of refurbishing the existing structure in order to minimise the CO2 and environmental impact of the project. Ultimately, a decision was made to replace the bridge, driven by the functional constraints related to the very low vertical clearance, which would significantly restrain any future enhancements to the railway line forming a part of the Trans-European Transport Network (TEN-T). The paper discusses non-conventional technical solutions that were applied to the design and construction of the bridge.
The Legacy of the Past: Geotechnical challenges from coal mining impacting major rail infrastructure.
Authors: McEwen Paul , Thomson Sue , Deakin Richard
Published: April 2024

The legacy from a long history of mining, quarrying and subsequent landfilling can present significant geotechnical challenges to infrastructure schemes. When upgrading existing rail lines through congested urban corridors there is little opportunity to avoid the risk. Understanding the legacy of the past and the risk posed to the construction and operation of both existing and new track and structures is key to building resilient structures and a sustainable railway for the future. The paper discusses how the coal mining risk was managed and through dialogue with Network Rail a balanced approach (considering safety, cost and resilience) was adopted to determine appropriate mitigation. It then discusses the challenges implementing drill and grout mitigation in a live rail environment, around buried infrastructure, through landfill areas and adjacent to water courses. All required as mitigation for a new flyover and viaduct structure between Huddersfield and Dewsbury.
Renewing Short-Span Existing Bridge Decks with CFRP Tendons for Durability
Authors: Onishi Yuki , Yamaguchi Kohei
Published: April 2024

Many short span bridges have sound substructures, but their superstructures have deteriorated and often have seismic performance problems. Considering factors such as the aging population, declining population, and financial constraints within the local communities, it is crucial for such bridge replacements to adopt "Smart Structures", such as maintenance-free structures. Therefore, this research was being conducted on precast PC (prestressed concrete) decks using carbon fiber reinforced polymer (CFRP), which are corrosion-resistant and can reduce maintenance costs. The Result showed that thin-walled PC decks with CFRP also had an same effective anchorage length for conventional standard PC steel strand wire. And, based on numerical analysis and loading tests, it was confirmed that the bending load carrying capacity of PC decks can be evaluated using the current design method.

Published: April 2024

The modern and sleek design of a new pedestrian, cycle bridge across the River Shannon is a vital link in the EuroVelo Route 2 Galway to Dublin Cycleway. The scheme was configured to act as a landmark structure, central to the proposed national cycle network, and a beacon for eco-tourism and patrons of active travel. It sought to overcome the severe space restrictions along riverbanks to construct the bridge and approaches over and within the Shannon Special Area of Conservation. The design aspired to deliver high quality finishes appropriate to a landmark structure in a thriving urban centre. The design needed to overcome severe geometric constraints to accommodate river navigation to land on the roof of the award winning Luan Gallery and altering the gallery to accommodate the bridge abutment in a visually seamless fashion. The scheme required the construction of the western approach ramps and boardwalk while maintaining the existing mature treeline along the river.

Authors: Kato Kentaro , Ishii Hironori , Yuki Yoichi , Miyashita Takeshi , Nishimura Kimitoshi
Published: April 2024

Stainless steel is a high-performance alloy with superior corrosion resistance compared to carbon steel. By applying stainless steel to corroded areas of a steel bridge, durability can be substantially improved. Our objective is to create a steel bridge that integrates hybrid structural components, which are composed of a combination of welded stainless steel and carbon steel, used to reinforce steel girder ends or their lower sections. Specifically, I-girder ends mainly subject to shear loads are our primary focus for corroded sections. This study examines the ultimate shear strength of welded steel girders comprised of stainless and carbon steel through load tests and numerical analysis. As a result, the ultimate strength of a hybrid girder can be assessed using a design equation for a homogeneous girder made of carbon steel by the Basler equation or an ultimate shear strength curve for stainless steel plates proposed in previous research in Japan.

Authors: Felber Lukas , Dietz Matthias , Müllers Ingo , Nöldgen Markus
Published: April 2024

This paper presents the approach of reusing existing concrete slabs in new constructions as a method to vastly reduce the environmental footprint of building structures. The general method including structural challenges are described concerning the reused slabs and their needed substructure. A life-cycle-assessment is conducted, stating that the reusage of concrete slab elements is potentially climate- and resource-neutral. The LCA-comparison between a conventional layout design and a design implementing reused concrete slabs shows a reduction of 27% and 32% of carbon and material footprint, respectively.
Sustainable concrete for the Uithoornlijn Project
Authors: Menting Michaël , van de Bilt Roy
Published: April 2024

The Uithoornlijn project involves the construction of a concrete pavement for buses with tram tracks, with a focus on achieving low CO2 emissions during construction. The largest share of emissions comes from cement production for the concrete. Through smart reduction in cement usage and the incorporation of various substitutions, the CO2 emissions have been reduced to approximately 1,400 tons.

The sustainable concrete mix requires attention to the slow strength development, especially in cold conditions. Insulating the concrete after placement helps retain heat and stimulate strength development. Sufficient time is allowed between pouring and loading the structure, and a maturity-strength relationship is established to manage this process. Risk management measures, such as adding additional dilations, are implemented to prevent damage from frost-thaw cycles and dilatation issues.

Using sustainable concrete mix yields substantial sustainability benefits and contributes to environmental goals. The project focuses on an optimized mix to reduce CO2 emissions without compromising the construction quality. With a well-thought-out plan and risk management, the construction can be successfully

executed, making a positive impact on the environment and enhancing the project's sustainability ambition.
Create Space For An Extra Intermediate Floor By Jacking
Authors: Rubeo Marco , Mollentze Michael , Harkin Daniel
Published: April 2024

An intermediate floor has been added to an existing 10 storied office reinforced concrete building in a busy city centre by jacking up the last two top floors by 3.6m. This solution was proposed as an alternative to the demolition of the roof and the building bottom up of the new floors which has allowed to significantly reduce the environmental impact of the project. Perimetral restraints have been installed to guide the structure during jacking and provide stability against wind loads. Jacking has been carried out with primary jacks installed in the axis of all building columns and secondary jacks installed on steel clamps working in friction and prestressed against the columns. Relative vertical movements between the columns have been controlled by a combined use of a synchro- pump and a laser-based monitoring system following the progress of the lifting.

Authors: Suzue Eri , Tsujimoto Taku , Eguchi Keiichi
Published: April 2024

Ohnaruto Bridge is a suspension bridge with a total length of 1,629m and has served for 38 years since opening in 1985. In 2001, flaking prevention work and surface coatings as salt damage countermeasures were carried out. Also, cross-sectional restorations were applied to deteriorated sections of the concrete slab. However, after 10 years of the repair work, in 2011, same deteriorations were observed again. Field investigations revealed that the main cause of the deterioration was macro-cell corrosion at the boundary between the repaired and unrepaired sections of the cross-sectional restoration. Impressed current cathodic protection method was adopted as a result of the verification to avoid the re-degradation and to save life cycle cost. This paper reports field investigations of the cause of the re-degradation, a study on cathodic protection, installation work of the adopted protection method, and its maintenance.
Enhancing Root-Deck Crack Detection in Orthotropic Steel Decks through Numerical Investigation of Eddy Current Techniques
Authors: Nitipong Praphaphankul , Ayako Akutsu , Sasaki Eiichi
Published: April 2024

Orthotropic steel decks in long-span steel bridges are susceptible to fatigue cracking, especially subsurface root-deck cracks. These cracks, hard to detect visually, can cause significant damage if unnoticed. Therefore, the early detection of these subsurface cracks is crucial in preventing further deterioration and ensuring the long-term sustainability of the bridge. In this study, a novel approach for the detection of subsurface cracks in orthotropic steel decks, utilizing new signal processing techniques based on eddy current technology (ECT), as well as optimizing the configuration of the ECT probes, is proposed. Through numerical analysis, response signals obtained from subsurface crack detection using ECT in frequency domains are extracted and analyzed with the proposed method to develop advanced feature extraction techniques that enhance sensitivity and improve the depth of subsurface crack detection. Additionally, various coil-based eddy current probes are examined to identify the most suitable probe configuration that offers robust performance in detecting subsurface cracks. The findings from this study contribute to the advancement of more effective strategies for subsurface crack detection in orthotropic steel decks by integrating advanced eddy current techniques, feature extraction methods, and optimized hardware configurations.

Sensitivity analysis of controlling indices and structural optimization for reinforced concrete shearwall residential towers
Authors: Yang Sheng , Zhao Xin , Hou Yuzhou
Published: April 2024

Reinforced concrete shearwall structure has been widely used in high-rise and super high-rise residential towers because of its high stiffness, high damping, low cost and good adaptability of component layout. Shearwall structure assembly are composed of shearwall limbs and coupling beam component. The shearwall is generally arranged along the vertical height, the lower part extends into the basement, and finally supports on the foundation. In addition, due to the needs of the entrance hall at the bottom of the residential tower or commercial functions, some shearwall assembly are often converted into frame structures at the bottom of the building, which is called frame-supported shearwall assembly. The structural system composed of full-height shearwall is called full-height shearwall structure, and the structural system composed of partial full-height shearwall and partial frame-supported shearwall is called partial frame-supported shearwall structure. The shearwall structure component need to consider both vertical gravity and lateral load to design the strength, stiffness and comfort of the structure. This paper studies the design of shearwall component of residential towers with a height of 100-200 meters, and adopts sensitivity analysis method to analyze the control indexes of components with different heights and positions. It is found that the design of low-zone components is usually controlled by the requirements of seismic ductility, while that of middle-zone components is usually controlled by the requirements of stiffness under earthquake or wind loads. High-zone components are usually controlled by structural requirements. On the basis of sensitivity analysis, this paper further discusses the design optimization method and flow of shearwall assembly. Finally, the sensitivity analysis and optimization design methods are discussed based on a real case of residential tower. The case analysis and optimization results verify the effectiveness of the relevant analysis and design methods.
Liaseal Design Concept - A new era of more durable and reliable segmental post-tensioned construction
Authors: Delport Emil , Geirinhas Nuno
Published: April 2024

The construction of prefabricated segmental viaducts in the United Kingdom are subject to a ban following major incidents (collapse) on structures due to anticipated corrosion problems of internal prestressing tendons. On the HS2 project, the Client's specifications opened the possibility of deviating from this ban by specifying the highest level of protection against stray current induced corrosion to the prestressing tendons according to engineering industry standards such as FIB Bulletin 33.

The highest protection level specified as PL3 requires the non-destructive monitoring of tendons against corrosion, by monitoring the impedance current levels of each tendon. To obtain high level results, each duct must be completely insulated to any other metallic components of a reinforced concrete structure and to avoid any leakage current in the concrete surrounding the tendon ducts.

The standard solution adopted on the prefabricated segmental viaducts (the use of a foam/silicone seals at the joints between segments) and the use of steel corrugated ducts, were therefore not suitable for PL3 level requirements because they do not provide an Electrically Insulated Tendon (EIT) system. To achieve an ETI system is to use electrically isolating materials not only for the duct (normally polypropylene (PP) or high-density polyethylene (HDPE)), but also at the PT anchor head using an isolation plate and encapsulating the strand within a plastic duct with an alkaline, cement- based grout with limited chloride content.

Freyssinet provided an electrical isolated PT anchor, adopted to connect with the HDPE duct but to further ensure continuity between the precast segments developed a duct coupler seal called “Liaseal” in compliance with FIB bulletin 75, to ensure a sealed polymer-duct system for internal bonded post-tensioning tendons to PL3 requirements.
Soho Loop Cantilever Footbridge
Authors: Dablin Ed
Published: April 2024

A new footbridge was required for the Soho Wharf residential development in Birmingham, UK. The bridge was to cross an existing canal from the development side and was to meet the far side through the parapet of a masonry arch footbridge without bearing onto the masonry arch barrel.

A low-cost static cantilever footbridge system was developed with no positive between the tip of the cantilever and the opposing side. This was in the form of an economic stiff and lightweight truss held down by a concrete kentledge under the back span. Existing structures were repurposed for use on both side of the canal.

The vertical deflection was found to be the governing design criterion. Sensibile construction sequencing and use of designed levelling devices were emoloyed to mitigate the risks associated construction and any longer-term movement.

Published: April 2024

The many bridges and viaducts in the Netherlands that were built in de 1950s and 1960s are approaching the end of their service life. Instead of replacement, which costs a lot of money and resources, reassessments and rehabilitation can be used to extend the expected service life of existing structures. For one of these structures, Spoorviaduct Uitgeest (a viaduct in the Dutch highway A9), a refined reassessment was requested to investigate whether this viaduct is sufficiently reliable.

In a comprehensive reassessment, performed by Arcadis Netherlands BV, the total viaduct was modelled in a 3D FE model. With this FE model, creep, shrinkage, permanent loads, traffic loads and imposed deformations were considered. It turned out that the cross-sectional shear checks and the rotational capacity were governing. By sufficient use of monitored material properties and refined shear calculations, sufficient shear capacity could be proven. Moment-curvature diagrams were used to prove enough rotational capacity.

Published: April 2024

Resource-efficient construction is a decisive factor for the development of sustainable economies and a sustainable way of life. In addition to material-saving technologies, the reactivation or conversion of existing structures is an effective approach to achieving resource efficiency. Particularly in densely built-up urban areas, there is the opportunity to reactivate elements of still existing but currently idle excavation pit structures, which belong to existing buildings. Also, permanent structural elements of existing buildings, such as basement-walls and base slabs, can be integrated into new excavation pit structures. The present paper reports on the experiences from construction projects, where elements of existing diaphragm walls as well as elements of existing buildings were integrated in the design and construction of new excavation pits.

Published: April 2024

Modeling of jaw bone defects after bisphosphonate administration is presently an urgent task of oral surgery. Methods for virtual modeling of pathological processes and ways for their elimination are becoming increasingly popular in experimental studies. However, biomedical research with experimental animals, which is strictly regulated by law, does not lose its relevance. The choice of a model for our study has been based on the assumption that bisphosphonate-associated osteonecrosis and jaw defect in experimental animals are identical to human clinical presentations. In addition, this study considers the development of devices for correcting biomechanical problems and positioning the jaw bone fragments. Simulated subtotal mandibular defects are accompanied by restricted mouth opening, malnutrition and, as a result, inhibited habitual functional activity in the experimental animals. This has served as a guide for incorporating the simultaneous fixation of fragments with a multifunctional device, such as with the mandibular exoskeleton, into the protocol of surgical intervention. Positive changes in the early postoperative period have been characterized by restoration of the biomechanical balance of the dentition. The findings provide evidence that it is necessary to modernize the device and to test the exoskeleton in patients with subtotal mandibular defects.

This community service activity (PKM) aims to introduce and train the community to process their rice harvests using appropriate technology, in the form of a grain peeling machine. The main target of this PKM activity is the people of the Jaya Mandiri Farmers Group in Batu Layang Village RT.04/RW.15, North Pontianak District, who still have limited means for their agricultural activities. The methods applied in this PKM activity are science and technology diffusion, socialization, and active community participation. So that with this PKM activity, the community has gained knowledge and skills in processing their post-harvest rice products, and it is hoped that this can help overcome their productivity problems due to limited agricultural facilities. Cleaning rice not only aims to remove empty grains, dirt and other foreign objects, but also increases the selling value per unit weight, increases the efficiency of drying and processing post-harvest products and extends shelf life. The working principle of the automatic rice cleaning tool is that when the rice is in the main reservoir, it then goes down through a small gap so that when it comes down it is cleaned with a fan so that the dirt stuck to the rice is blown away and the clean rice enters the reservoir section. The construction of this rice cleaning machine is divided into a hoper as a place to input rice, a crankshaft system, while the drive system consists of an electric motor, pulley, belt, pegs, bearings. With this device, the process of cleaning rice can be carried out simply and easily, and the process time, namely cleaning time, is shorter. With a shorter processing time, the production rate per unit time becomes greater.
Improving the quality of agricultural products is very important in supporting food security and farmer welfare. One of the key aspects in ensuring the quality of agricultural products is the post-harvest processing process, especially the rice cleaning process. In this context, this research aims to optimize the rice refining process through the implementation of effective applied strategies. This study was conducted through a comprehensive series of laboratory experiments and field tests. Refining methods involving a combination of traditional and innovative technologies were evaluated to find the most efficient strategy for improving rice quality. The research results show that the use of a combination of certain technologies can increase the efficiency of rice cleaning, as well as reduce yield losses and increase the selling value of the product. This research makes a significant contribution to the development of agricultural practices that are sustainable and oriented towards quality results. These findings have direct implications for farmers in increasing the competitiveness of their products in local and global markets, as well as in supporting government efforts to achieve national food security goals.

Limbah medis memberikan ancaman serius terhadap kesehatan lingkungan dan memerlukan penanganan serta pengelolaan khusus. Permasalahan semakin berkembang dengan semakin meningkatnya jumlah fasilitas pelayanan kesehatan. Tenaga kesehatan harus memiliki pengetahuan dan sikap yang baik tentang pengelolaan limbah medis. Sasaran pengabdian kepada masyarakat ini diberikan kepada pengelola limbah medis di setiap fasilitas pelayanan kesehatan, dengan pelatihan yang diberikan diharapkan pengetahuan dan praktik tentang pengelolaan limbah medis meningkat. Peserta pelatihan adalah pemilik atau kepala klinik atau penanggung jawab instalasi pemeliharaan sarana prasarana rumah sakit di wilayah kecamatan Grogol Petamburan, Jakarta Barat. Jumlah peserta pelatihan adalah 33 perwakilan (43%), yang berasal seluruh fasyankes yang berada di wilayah Grogol Petamburan. Sepertiga (33%) tenaga kesehatan tidak dilatih / dipaparkan tentang pengelolaan limbah medis, walaupun SK tentang pengelolaan limbah medis (82%) sudah diterbitkan berikut juknis (82%) dan standar prosedur operasionalnya (88%). Praktik pemilahan limbah dilakukan oleh hampir seluruh fasyankes (94%), 73% fasyankes yang mencatat jumlah produksi limbah medis dalam logbook hariannya, pengolahan limbah medis menggunakan jasa pihak ketiga (100%), lebih dari separuh (52%) petugas kebersihan dan staf medis belum pernah mengikuti pelatihan pengelolaan limbah medis dan hanya sedikit petugas kebersihan yang tidak menggunakan APD saat melakukan pengelolaan limbah medis (6%). Banyak petugas kebersihan atau karyawan yang belum pernah mengikuti pelatihan mengenai pengelolaan limbah medis, perlu upaya sosialisasi terus menerus oleh pihak-pihak berkepentingan agar tercapai pengelolaan limbah medis terstandar di setiap fasilitas pelayanan kesehatan. Diperlukan penerapan aturan pengelolaan limbah medis secara ketat, fasilitas pelayanan kesehatan wajib melatih tenaga kesehatannya. Pelatihan dan pelatihan ulang mengenai limbah medis harus direncanakan dan dilaksanakan.

Las dosis de paclobutrazol que reducen la altura del tallo floral o modifican el aspecto visual pueden ser distintas para cada cultivar. En esta investigación se evaluó el efecto de ocho concentraciones de paclobutrazol en la altura del tallo, aspecto visual, periodo de antesis y distribución de biomasa de Lilium asiático cv. Litouwen. Dieciocho bulbos fueron sumergidos por 24 h en 5 L de las siguientes soluciones: 0 (control), 2.5, 5, 10, 20, 40, 100, 200 mg L-1 de paclobutrazol. Transcurrido el tiempo, tres bulbos se plantaron en macetas con 2.5 L de tezontle y se distribuyeron al azar en el interior de un invernadero. Durante el ciclo del cultivo, de 2022, la humedad del sustrato se mantuvo con solución Steiner. Los resultados se procesaron con análisis de varianza y pruebas de comparación de medias (Tukey, p≤ 0.05). La altura de los tallos florales fue de 61.5, 56.6, 43.4, 29.1, 18.4 y 14.1 cm con 0 o 2.5, 5 o 10, 20, 40, 100 y 200 mg L-1 de paclobutrazol respectivamente. El número de hojas y el área foliar disminuyeron, pero el diámetro del tallo, índice de verdor, biomasa seca de raíces, botones florales, tiempo a la floración y periodo de antesis se incrementaron a partir de 40 mg L-1. En Lilium ‘Litouwen’ se requieren dosis de 40 o 100 mg L-1 de paclobutrazol para obtener plantas compactas con follaje verde intenso y botones florales llamativos, lo que ayudaría a su comercialización como plantas de maceta.
Ghostly Narratives and Transatlantic/Global African Identity Politics
Authors: Logan Kossi Mawuena
Published: April 2024

Abstract: Notwithstanding that any allusion to ghosts raises eyebrows, the term congruently evokes metaphysical and existential questions, concepts, and paradigms: death, hauntings, exorcism, healing, and mourning. It may speak to traumatic events—manifested spectrally—that leave an imprint on the psyche. The expression "to lay the ghost to rest" alludes to hauntings and processes of exorcism and healing. This article investigates how these processes condition and define identity politics in the Black and transatlantic world. It taps into contemporary African literature in an attempt not only to map out the literary and social functions of ghosts—as metaphors for historical traumas—and their impact on discursive identity formation but also to probe the role of mourning in healing the haunted. It calls for a critical and sustained evaluation and even denunciation of the historical and traumatic events of slavery and colonialism to avoid a repeat, for the benefit of humanity.
Reimagining the Gospel of Efficiency
Authors: Vaca Daniel
Published: April 2024

Abstract: While historians of modernity often associate efficiency with the so-called Efficiency Movement of the Progressive Era, the ideal of efficiency remains powerful today. But what is efficiency? What does it demand and promise? This article addresses these questions by exploring examples of efficiency ideology from the early twentieth century. Focusing especially on the careers of the financial guru Roger Babson and the minister Reverdy Ransom, these examples not only illustrate how and why religious initiatives and ideas became conduits for “the gospel of efficiency” but also reveal efficiency’s tendency to produce distinctions that define many people, practices, and priorities as waste. Although often seen as a benevolent and even scientific ideal, efficiency ideologies have promised to create a better and more prosperous world while often conferring prosperity unequally. Highlighting efficiency’s appeal and peril, this article invites readers to reimagine the visions of prosperity that efficiency continues to call into being. RESUMEN: Mientras los histórianos de la modernidad a menudo asocian la eficiencia con el llamado Movimiento de Eficiencia de la Era Progresista, el ideal de eficiencia sigue siendo poderoso en hoy día. Pero ¿qué es eficiencia? ¿Qué es lo que exige y promete? Este articulo hablara de estas preguntas explorando ejemplos de ideología de eficiencia de los principios del siglo veinte. Especialmente concentrando en las carreras del gurú financiero Roger Babson y el ministro Reverdy Ransom, estos ejemplos no sólo ilustren como y porque iniciativas e ideas religiosas vienen siendo conductos para “el evangelio de la eficiencia” sino que también revelan la tendencia de la eficiencia a producir distinciones que definan varias personas, prácticas y prioridades como desperdicio. Aunque a menudo se las consideran un ideal benévolo y también científico, las ideologías de la eficiencia han prometido crear un mundo mejor y más próspero, mientras a menudo confieren prosperidad de manera desigual. Destacando lo atractivo y lo peligroso de la eficiencia, este artículo invita a los lectores a reimaginar las visiones de prosperidad que la eficiencia continúa llamar a existencia.
Horror and Loss in Samuel Fuller's Shock Corridor and Jordan Peele's Get Out
Authors: Craven Alice Mikal
Published: April 2024

Abstract: Samuel Fuller's Shock Corridor (1963) and Jordan Peele's Get Out (2017) were both created during dreadful points in America's history. But Fuller hopes his film will be seen as science fiction as opposed to real life as he states in his autobiography of 2002. Peele attests wisely that Fuller's hope will never be fulfilled. Both works, though filmed in different times, show a troublesome world. They both depict a fragile America. Both protagonists had a sharper eye or were better witnesses to their worlds. A sharper vision is to be valued. Johnny of Shock Corridor is a journalist delving into the dangers of a mental institution. Chris, a photo fan, in the end comes to his close vision that he does not belong in the world of the film Get Out . The fear of loss exists in both Fuller and Peele. This article explores how these two films reveal the fragility of America.
Against Dispossession: Re/membering My Cousin Héctor, the Huachicolero
Authors: Walsh Michaela
Published: April 2024

Abstract: This article examines the state-owned oil giant Pemex, its role in building Mexico's middle class, and the country's continued struggle for resource sovereignty. It argues that gas theft is a potential albeit problematic form of resistance to social death in the face of dispossession, or the "bleeding out" of Mexico's national body to social and economic violence. I use an autoethnographic methodology to depict how one family member's aspirations to join Mexico's middle class turned to modern-day "banditry," for which he paid the ultimate price. Through the lens of my cousin's experience as a huachicolero, or fuel thief, I explore the relationship between neoliberal policies, violence, and resistance in contemporary Mexico.
