Authors: Podstawka Michal , Snop Vladimír , Bělský Petr , Kutiová Kristýna
Published: November 2021

The operational safety and reliability of an airplane must be an integral part of its design. The use of suitable materials that pass material certification tests is very important for a new aircraft design. The next part is testing specific samples, sub-components, and components such as the aileron. The paper deals with a non-destructive evaluation of composite primary structural part fatigue tests in accordance with damage tolerance philosophy considering impact damage presence. NDT methods such as visual, eddy current, and ultrasonic testing included phased array technique, are used for the inspections. A schedule of inspections was created, and structural durability was verified.
Cavitation shapes measurements in piston-ring lubrication and their link to lubricant properties
Authors: Dellis Polychronis
Published: November 2021

The emissions control regulations introduced by governments are set to improve engine quality and reduce the impact automobiles have on the planet. The regulations imposed on the manufactures have proven very difficult to meet. To this effect some of the leading names in the industry were pushed to invest significant funding in research, development and optimisation of combustion, powertrain and tribology inside the ICE. Their goal is reduction of fuel consumption and emissions while increasing performance and durability. The piston-ring and cylinder-liner interaction is the major source of frictional losses for reciprocating ICEs and so, it is important to avoid any failure of piston-rings to effectively control lubricant transport from the sump onto the cylinder walls and further to the combustion chamber. This lubricant will participate in the emissions through absorption and desorption of fuel in the oil film at the cylinder walls, also resulting in lubricant contamination and consumption. The objective of this project is to assist with the investigation of phenomena occurring in the cylinder liner and piston-ring interaction under different operating conditions. The following investigations have been carried out, flow and cavitation visualisation in a model lubricant rig and cavitation visualisation in a newly designed optical engine.
Experimental-numerical validation of the curing reaction of snap-cure polymer systems for component families of small batch sizes and high diversity
Authors: Stanik Rafal , Geller Sirko , Müller Michael , Stanik Tomasz , Gruhl Andreas , Knorr Alexander , Antonowitz Henrik , Langkamp Albert , Gude Maik
Published: November 2021

The efficient production of component families of small batch sizes and high diversity requires numerical analyses of manufacturing processes, especially for complex shaped components made of fibre-reinforced thermosets. In the case of snap-cure systems, curing takes place in a very short time and the exothermic reaction can lead to accumulation of heat and inhomogeneous curing. In order to achieve a reliable production of composite components, a numerical analysis of the curing process is necessary. Especially the practice-oriented and timesaving determination of the thermal conditions during the curing process is essential for the industrial application. Therefore, an experimental-numerical approach to predict the curing process was presented, which includes the analytical as well as the experimental determination of numerous thermal and thermochemical material parameters and models for snap-cure thermosets. The experimentally determined material parameters and models for the description of the material and structural behaviour are validated and evaluated by numerical simulations. In addition, the developed finite element models were used for the manufacturing process design of a complex component demonstrator.
Modern nanoscience: Convergence of AI, robotics, and colloidal synthesis
Authors: Epps Robert W. , Abolhasani Milad
Published: November 2021

Autonomous experimentation and chemical discovery strategies are rapidly rising across multiple fields of science. However, closed-loop material development approaches have not been widely employed in colloidal nanoscience mainly due to the challenges in synthesis space size, sensitivity to reaction conditions, and the complexity of monitoring multiple synthesis outputs. Recent advancements in automated reactor designs for controlled and reproducible nanocrystal synthesis and intelligent experiment selection algorithms are leading to wider propagation of artificial intelligence-guided autonomous experimentation techniques in colloidal nanoscience. This review will cover the current literature on closed-loop, autonomous platforms for accelerated development of colloidal nanomaterials and discuss the critical features and strategies for developing autonomous robotic experimentation systems suitable to problems in colloidal nanoscience, while providing the context, effectiveness, and prospects of each technique. Then, we will discuss some immediate opportunities in the field for more rapid technological advancement and colloidal nanomaterial discovery.
The nonlinear optical absorption and optical limiting properties of noble metal-doped ZnO films
Authors: Tian Peiran
Published: November 2021

Herein, pure ZnO, Ag-doped ZnO, and Cu-doped ZnO films with excellent ultrafast (femtosecond) nonlinear absorption/limiting behavior were deposited on quartz substrates by magnetron sputtering. From the open-aperture Z-scan result, under femtosecond pulses, the strong two-photon absorption (TPA) behavior of metal-doped ZnO was found, and the absorption coefficient was found to be several times that of pure ZnO, which will expand the design and application strategies of metal-doped wide-gap semiconductor materials in the field of nonlinear devices. Moreover, the samples exhibited superior optical limiting behavior with respect to the optical modulation characteristics of the input–output laser. The mechanism of optical limiting effects is induced by the TPA-induced reverse saturable absorption of the deep level and low excited state processes.
Time of sowing influences wheat responses to applied phosphorus in alkaline calcareous soils in a temperate climate
Authors: Mason Sean , McDonald Glenn
Published: November 2021

Adequate phosphorus (P) nutrition underpins cereal production in Australia and soil tests are commonly used to adjust fertiliser rates. The critical soil test values (i.e. required to achieve 90% of maximum yield) used for fertiliser recommendations have been derived from historic fertiliser trials sown mainly in May and June, with sowing date not considered in the interpretation of the critical values. However, the availability of long-season wheat cultivars has meant that crops can now be sown earlier. Experiments were conducted to investigate the effect of sowing time on optimum P rates for yield. Bread wheat (Triticum aestivum L.) cvv. Mace and Trojan were grown at five P rates at three sites in the Mid-North and Yorke Peninsula of South Australia, on alkaline calcareous soils, in each of 2 years. Both varieties showed similar responses to P. Crops sown in late April–early May often had a low optimum P rate, and there was a general trend for the optimum P rate to increase with later sowing. However, early sowing reduced the optimum P rate only when April rainfall was high. Grain yield responded positively to increases in vegetative growth from P fertiliser, and the optimum P rate for vegetative growth and grain yield were correlated. Early sowing increased grain P concentrations, and P removal rates were similar to, or greater than, those of later sown crops. Sowing in April–early May can reduce the P requirements of wheat, but there is an increased likelihood of a negative P balance; therefore, monitoring of soil P reserves will be required. A relationship between the optimum P rate for yield and the partial nutrient balance may provide a benchmark to help manage P.
Distinct species hidden in the widely distributed coral Coelastrea aspera (Cnidaria, Anthozoa, Scleractinia)
Authors: Mitsuki Yuta , Isomura Naoko , Nozawa Yoko , Tachikawa Hiroyuki , Huang Danwei , Fukami Hironobu
Published: November 2021

Species identification is key for coral reef conservation and restoration. Recent coral molecular-morphological studies have indicated the existence of many cryptic species. Coelastrea aspera (Verrill, 1866) is a zooxanthellate scleractinian coral that is widely distributed in the Indo-Pacific. In Japan, this species is distributed from the subtropical reef region to the high-latitudinal non-reef region. Previous studies have reported that C. aspera colonies in the non-reef region release egg-sperm bundles (bundle type), whereas those in the reef region release eggs and sperm separately (non-bundle type) and release planula larvae after spawning. This difference in reproduction might be relevant to species differences. To clarify the species delimitation of C. aspera, the reproduction, morphology and molecular phylogeny of C. aspera samples collected from reef and non-reef regions in Japan were analysed, along with additional morphological and molecular data of samples from northern Taiwan. The results show that C. aspera is genetically and morphologically separated into two main groups. The first group is the non-bundle type, distributed only in reef regions, whereas the second group is the bundle type, widely distributed throughout the reef and non-reef regions. Examination of type specimens of the taxon’s synonyms leads us to conclude that the first group represents the true C. aspera, whereas the second is Coelastrea incrustans comb. nov., herein re-established, that was originally described as Goniastrea incrustans Duncan, 1886, and had been treated as a junior synonym of C. aspera.
Hooroo mates! Phylogenomic data suggest that the closest relatives of the iconic Tasmanian cave spider Hickmania troglodytes are in Australia and New Zealand, not in South America
Authors: Kulkarni Siddharth , Hormiga Gustavo
Published: November 2021

Hickmania troglodytes is an emblematic cave spider representing a monotypic cribellate spider genus. This is the only Australian lineage of Austrochilidae while the other members of the family are found in southern South America. In addition to being the largest spider in Tasmania, Hickmania is an oddity in Austrochilidae because this is the only lineage in the family bearing posterior book lungs, tarsal spines and an embolar process on male pedipalps. Six-gene Sanger sequences and genome scale data such as ultraconserved elements (UCEs) and transcriptomes have suggested that Hickmania troglodytes is not nested with the family of current classification, Austrochilidae. We studied the phylogenetic placement of Hickmania troglodytes using an increased taxon sample by combining publicly available UCE and UCEs recovered from transcriptomic data in a parsimony and maximum likelihood framework. Based on our phylogenetic results we formally transfer Hickmania troglodytes from Austrochilidae to the family Gradungulidae. The cladistic placement of Hickmania in the family Gradungulidae fits the geographic distribution of both gradungulids (restricted to Australia and New Zealand) and austrochilids (restricted to southern South America) more appropriately.
“Suspect-Proof”? Paranoia, Suspicious Reading, and the Racial Passing Narrative
Authors: Moynihan Sinéad
Published: November 2021

This short essay considers racial passing narratives in relation to the “postcritical turn,” highlighting the proliferating reappraisals of the practices of “suspicious” or “symptomatic” reading in literary studies and the extent to which passing narratives offer an opportunity to test some of the claims of this body of scholarship. The utility of the passing narrative for this critical project lies in its persistent, self-conscious foregrounding of reading practices. Revisiting passing narratives in light of postcritique reveals that symptomatic reading is not a monolithic practice; rather, there are multiple ways of reading suspiciously. Moreover, and more importantly, passing narratives disclose that what has now become an orthodoxy in postcritique—that attitudes such as “paranoia,” “suspicion,” and “vigilance” profoundly limit “the thickness and richness of our aesthetic attachments”—ignores contexts, like that of a passer in a white supremacist society, in which such strategies are not a choice but are essential for survival (Felski 17). The key question posed herein is: What forms of privilege enable a reader to relinquish her attachment to paranoia, suspicion, and vigilance; to opt for openness rather than guardedness, submission rather than aggression (21)? Narratives of racial passing provide one answer to that question.

The key question posed herein is: What forms of privilege enable a reader to relinquish her attachment to paranoia, suspicion, and vigilance; to opt, as Rita Felski advocates, for openness rather than guardedness, submission rather than aggression?
Fern fronds that move like pine cones: humidity-driven motion of fertile leaflets governs the timing of spore dispersal in a widespread fern species
Authors: Suissa Jacob S
Published: November 2021

Background and Aims

The sensitive fern, Onoclea sensibilis, is a widespread species in eastern North America and has an atypical timing of spore dispersal among temperate ferns. During early summer, this dimorphic species produces heavily modified spore-bearing fronds with leaflets tightly enveloping their sporangia and spores. These fronds senesce and persist above ground as dead mature structures until the following early spring when the leaflets finally open and spores are dispersed. While this timing of spore dispersal has been observed for over 120 years, the structural mechanisms underpinning this phenology have remained elusive.

Methods

Based on field observations, growth chamber manipulations and scanning electron microscopy, the mechanisms underlying this distinctive timing of spore dispersal in the sensitive fern were investigated.

Key Results

I show that fertile leaflets of the sensitive fern move in direct response to changes in humidity, exhibiting structural and functional parallels with multicellular hygromorphic structures in seed plants, such as pine cones. These parallels include differences in cellulose microfibril orientation in cells on the abaxial and adaxial sides of the leaflet. The dynamics of this hygroscopic movement concomitant with regular abscission zones along the pinnules and coordinated senescence lead to the specific timing of early spring spore dispersal in the sensitive fern.

Conclusions

While hygroscopic movement is common in seed-free plants, it mostly occurs in small structures that are either one or a few cells in size, such as the leptosporangium. Given its multicellular structure and integration across many cells and tissues, the movement and construction of the sensitive fern pinnules are more similar to structures in seed plants. The evolution of this complex trait in the sensitive fern efficiently regulates the timing of spore release, leading to early spring dispersal. This phenology likely gives gametophytes and subsequent sporophytes an advantage with early germination and growth.
White Ethnicity in the Urban Crisis: Newark’s Italian Americans
Authors: Carnevale Nancy C
Published: November 2021

Scholars have largely understood the urban crisis, including racial violence, as a matter of Black versus white, with white ethnics in possession of a largely inconsequential ethnicity. An examination of two community leaders from Newark’s North Ward reveals competing Italian American perceptions of the urban crisis. Anthony Imperiale, the race-baiting demagogue and politician, has been portrayed by the media and by scholars as the lone voice of the North Ward. Stephen Adubato argued that urban white working-class ethnics like Italian American Newarkers were reacting to economic hardship at a time when they believed the government was advantaging African Americans. Rather than foster a white identity and anti-black sentiment, Adubato aimed to promote stronger Italian American ethnicity as a basis for making claims on resources. A consideration of the two men, using newspaper accounts and archival sources, illustrates that Newark’s Italian Americans as a distinct ethnic group had diverse if at times overlapping interpretations of their experience of the urban crisis rooted in identification by race on the one hand and ethnicity on the other. The attitudes toward and relations with African Americans represented by both men were grounded in real and imagined socioeconomic, political, and cultural realms within the specific racial context of the era and the challenges of the urban crisis which extended to the Italian American community.
Adding abductive reasoning to a propositional logic
Authors: Rasga João , Sernadas Cristina
Published: November 2021

We present a technique for obtaining a logic with abductive reasoning extending a given propositional logic. Abduction, along with deduction and induction, is recognized as important for machine learning, namely in identifying possible causes that may lead to the occurrence of an event and in providing new ways for a computational device to achieve a certain objective. Each rule in the original calculus induces a set of multiple-conclusion abductive rules. Moreover, rules stating generic properties of abduction have to be added. In the induced logic, the deductive mechanism of the base logic coexists with this abductive component. A new notion of a multiple-conclusion derivation had to be developed. Due to the canonical nature of obtaining such a logic, we prove the preservation of soundness, completeness, decidability and computational complexity. These concepts and results are illustrated in a robot navigation problem using a multimodal logic.
One Hundred Years of Solitude and Its Influence in Japan
Authors: Robledo Gonzalo
Published: November 2021

The Japanese translation of One Hundred Years of Solitude, published in 1972, was a landmark in Japan’s twentieth-century cultural life. From literature to cinema, from drama to anime film, García Márquez’s masterpiece has been hailed as a source for inspiration or as a professional milestone by leading Japanese creators. Authors such as Kenzaburō Ōe (Nobel laureate, 1994), Natsuki Ikezawa, and Kobo Abe openly acknowledged having undergone literary influence from the Colombian writer, while Haruki Murakami scholars point out how magical realism serves as García Márquez’s tool in depicting multiple explanations for a reality populated by traumatized characters. The subsequent Japanese publication of the near-totality of the Colombian Nobel laureate’s oeuvre, moreover, has helped bring into view a great many coincidences between magical realism and the subject matter and techniques of Japanese literary works produced since the end of the nineteenth century, when Japan ended its voluntary isolation and opened itself up to the West. The imprint of García Márquez on Japanese culture brings out parallels between two distant literary traditions that offer a reality different from that of the European, modifying it with magical or animistic elements. The legacy of GGM in cinema is present above all in the animated films of the Ghibli Studio, which submerge the viewer in a reality so palpable that one is induced to unquestioningly accept extravagant or implausible events.
Myth and Poetry in Macondo
Authors: López-Baralt Mercedes
Published: November 2021

One Hundred Years of Solitude has frequently been approached from a historical perspective, focusing on the colonial imprint in Latin America’s destiny. Yet in his Nobel Prize acceptance speech, García Márquez made it clear that he wished to be remembered for the poetry that permeates his writing. This article is inspired by this assertion, as well as by a quote from Ernesto Sabato, who claims that for philosophers and artists, myth and poetry are keys to access the Absolute: truth, beauty, and perfection. Taking into account the few previous attempts to pursue these motifs in the novel, the article undertakes a search of the traces of both myth and poetry in García Márquez’s opera magna. The faces of myth are many: Oedipus, prophecies, magic, utopia, the mandala of the tree of life, cyclical time, alchemy, one-dimensional characters (actants), genesis, and apocalypse. On the other hand, poems and metaphors are ever present in the novel. This search led to a new reading of One Hundred Years of Solitude, discovering García Márquez’ celebration of ambiguity. For the novel’s conclusion moves the reader to two opposing interpretations: apocalypse (the destruction of Macondo and the solitary Buendía dynasty) and hope (solidarity in a new mankind). The possibility of clashing readings confirms Italo Calvino’s definition of a classic as a book that never finishes saying what it has to say.
The Protean Viewpoint in One Hundred Years of Solitude
Authors: Camayd-Freixas Erik
Published: November 2021

Point of view is a primary category of narrative, given that other elements such as characterization, description, language, worldview, structure, and genre, if they are to be convincing, need to be consistent with the adopted vantage point. In One Hundred Years of Solitude, where there is little direct dialogue, a polyvalent and multilayered diegesis, where an uncertain narrator recounts what different characters see, feel, and say, becomes a signature technique. According to Boris Uspensky, the “ideological point of view,” defined as the way of looking at the world conceptually, is not explicitly expressed, but found rather at the phraseological level of the narrative—marking a return to rhetorical criticism. “Many years later, before the firing squad, Colonel Aureliano Buendía would remember that remote afternoon when his father took him to discover ice.” From the outset, the viewpoint is marked by extreme shifts in person, character, time, tenses, and space, mapping its polyphony. This polyvalent narrator shifts from character to character, while the phraseology evokes different genres of the marvelous (myth, legend, folk tales, children’s stories, fairy tales, chronicles, travelogues, and ethnographic accounts). This overlay supports the verisimilitude of magical realist narrative. Ultimately the authorial mask is revealed to be Melquiades, himself a protean figure, a gypsy, merchant, explorer, ethnographer, inspired in Don Quixote’s Cide Hamete Benengeli. The narrator’s worldview coincides with the characters, such that no one shows surprise before the supernatural. The ideology appears naive, provincial, rural, primitive, and akin to outsider art, while maintaining a sophisticated technique.
García Márquez and the Global South
Authors: Armillas-Tiseyra Magalí
Published: November 2021

Even when its focus is ostensibly local, Gabriel García Márquez’s literary output registers the global forces—and, specifically, the imbalances of economic, political, and cultural power—that condition those local circumstances. These same forces are the dynamics that define the Global South in the present. Following the most recent work in the field, the Global South is here understood not simply as a place name or post–Cold War substitute for the Third World, but as the resistant political imaginary arising from the mutual recognition of shared or analogous circumstances by marginalized or dispossessed groups throughout the world. This article explores the three principal intersections between García Márquez’s work and the Global South understood as a relational and analytical category. First, it outlines the ways in which his work registers global—and, importantly, South-South—circuits of exchange, opening up new comparative itineraries. Second, it elaborates the ways in which these comparative connections build toward a critique of the global system, such that García Márquez provides both the grounds and a model for what this article calls “Global South thinking.” The final section addresses the circulation and influence of García Márquez’s work in the literatures of the Global South. Much of the existing commentary on this topic (his influence on Third World, postcolonial, or even world literature) has focused on magical realism and One Hundred Years of Solitude. But, the article shows, works such as The Autumn of the Patriarch and Chronicle of a Death Foretold have also had a profound influence, on both individual texts and their reception.
Fate and Free Will in Chronicle of a Death Foretold
Authors: Swanson Philip
Published: November 2021

In García Márquez, the magical is associated with fantasy, myth, literariness, and the unknowability of reality, while realism suggests seeing through fictitious versions of reality constructed by hegemonic discourses. Chronicle of a Death Foretold (1981) is about fate and ambiguity, but also encourages the challenging of convention and the assertion of an independent identity: the “magic” of the imagination is a path to alternative ways of being and a new reality. The title suggests the circularity of a mystical destiny and the investigative desire to recuperate historical truth. Santiago Nasar’s death is inevitable because of an honor code rooted in religious and social conformity (his killing is necessary to purify the Vicario family name following a bridegroom’s discovery that his bride, Angela Vicario, has already lost her virginity, possibly to Santiago). Moreover, there is a performative, ritualistic, sacrificial dimension to the planning of the death, as Angela’s brothers act out their compulsion according to what they believe is required of them. Behind this is the idea that the magic of love has become little more than a social contract and has ceased to be “real.” The investigation of the detective-like chronicler (into a real event now being transformed into a fiction) implies a quest for “truth,” and the final outcome is a not entirely ironic achievement of “true” love, independently chosen. This article explores how agency and authorship are mobilized to test the limits of fatalism and convention.
The Filmic Literary Works of Gabriel García Márquez
Authors: Rocco Alessandro
Published: November 2021

Cinema is a very important area of GGM literary activity, which the author conceived as another way to tell stories, in parallel and connected to the ways novels/stories and journalism tell stories of their own. This article addresses the work of García Márquez as a filmic writer. After briefly explaining the influence of cinema on his literary education, the article focuses on some problems in the writing of subjects and screenplays in relation to film production, which also concerned García Márquez. His film work is discussed in chronological order, while also highlighting the more relevant thematic and aesthetic elements. The theme of destiny opens and closes the discourse, given that it is present both in the first and last important screenplays by the author, Tiempo de morir and Edipo Alcalde, linked to the influence of Sophocles’s Oedipus Rex. Another relevant theme is that of the tension between realistic representation and the different forms of transfiguration of reality, via fantastic elements, absurd situations, and hyperbolic intensifications. Such aspects may be found in the screenplays of many films written by GGM between the 1970s and 1980s: Presagio, El año de la peste, María de mi corazón, Eréndira, Un señor muy viejo con unas alas enormes, and the series Amores difíciles. Finally, the article focuses on some unexecuted projects: unpublished screenplays or film stories, such as “Dios y yo”, “Para Elisa”, and “Blacamán”, which show the richness of the filmic imagination of García Márquez.
Modernization and Culture in García Márquez’s Caribbean
Authors: Velasco Marcela
Published: November 2021

Gabriel García Márquez offers rich accounts of the Colombian Caribbean’s experience with the historical forces of progress that test traditional societies and their predominant values and attitudes. Colombian historiography identifies various broad stages of secular change in the Caribbean since independence: (1) the emergence of enclave economies, (2) the arrival of people fleeing violence, (3) the foundation of new settlements in the hinterland, (4) the rapid industrialization of Barranquilla, and (5) the region’s full integration into the national project. García Márquez’s fictional towns and generations exist in phases 1–4, which roughly correspond with one hundred years of postindependence history. His Caribbean, like the real one, follows a messy path to modernity where traditional values are tested. It has fuzzy political, cultural, and economic borders and is governed by overlapping elites who, unintentionally, leave vacuums of power for the reproduction of morally loose, intercultural, and miscegenated societies. These societies see the dominant civilization and are familiar with its technologies and social projects. News of progress comes to them in leaf storms, books of knowledge brought by gypsies, trains arriving out of nowhere, or the speeches of shady politicians. This article argues that such broad changes shape values and attitudes as people adapt to new patterns of organization. In the standard modernization account, traditional values (i.e., survival/family orientation) give way to secular values (i.e., self-expression/trust in anonymous institutions). But this cultural transition is neither smooth nor complete. Rather, traditional and secular values coexist in constant tension, and García Márquez shows how.
Inequality and Day-to-Day Encounters with
Media
Authors: Prendella Kate , Alper Meryl
Published: November 2021

Disabled people have a complex relationship with media as content consumers, activist organizers, and technological innovators. This chapter highlights the underexplored theoretical connections between disability and media sociology and suggests how disability can inform and improve the sociological study of media. The authors draw on various cultural theories and concepts to emphasize how inequalities are perpetuated in disabled individuals’ day-to-day-media encounters. First, the chapter reviews media “access work,” or the paid and voluntary efforts of individuals who labor to make media technologies accessible, and how this work has historically been devalued and rendered invisible. Next, the chapter discusses social media and online communities as powerful resources for generating and sharing knowledge among people with disabilities, while contending with major structural limitations to their participation. Lastly, the chapter explores mass media and the tensions inherent in disability media representation both on- and off-screen. The discussion concludes with suggested areas for future research at the intersections of disability and media sociology that take seriously the mediated work of disabled individuals, employ explicitly anti-ableist approaches, and recognize the need for cultural accessibility.
Framing Disability in Fashion
Authors: Foster Jordan
Published: November 2021

The fashion industry has long neglected people with disabilities, opting instead for a cast of uniformly slender and (overwhelmingly) White models. But recent efforts toward diversity and inclusion suggest that change may be underway. This chapter examines these changes with a focus on fashion media published online. Specifically, this chapter looks to a collection of 50 editorial articles published by Teen Vogue between 2018 and 2020 to determine how disability is framed for consumers. It does this within a broader discussion on the cultural logics and industry conventions that shape the production of fashion content. The findings reported here suggest that online fashion media may hold unique opportunities for diversity and inclusion, with stories and images that cast disability in new and less narrow terms than have been previously reported. These include terms related to the importance of representation across cultural industries and stories that center disability rights in focus. Moving forward, more work is needed to ensure that this representation carriers forward in cultural productions within and outside of the fashion industry.
Disability and the Transition to Adulthood in the
United States
Authors: Bardo Anthony R. , Vowels Ashley
Published: November 2021

This chapter provides a synthesis of the literature on the transition to adulthood among emerging adults with a disability in the United States. The life course paradigm was used to frame the discussion in the context of demographic trends and contemporary circumstances regarding major life transitions in the areas of education, employment, independent living, and sex, marriage, and parenthood. A critical assessment of the current state of the literature from a social versus medical model of disability in these central life domains provides a foundation from which sociologists can explore processes of cumulative inequality embedded in the relatively uncharted lives of transition-age youth with a disability.
Disability, Violence, and Prison
Authors: Ostrander Nomi
Published: November 2021

This chapter explores the intersection of disability, race, and violence within the context of US carceral settings. To foreground this discussion, the author traces the War on Drug’s impact on prison population growth. These policies simultaneously increased community violence that resulted in countless disabilities, along with thousands of deaths. The surviving combatants were often left to serve time in prisons that were not equipped to house and support individuals with disabilities and complex medical needs. Once incarcerated, many people with disabilities experience higher rates of violence and manipulation from other inmates and guards. The chapter concludes with several recommendations to improve conditions for people with disabilities who are incarcerated or face incarceration for criminal offenses.
Activism, Inclusion, and Social Justice
Authors: Prince Michael
Published: November 2021

This chapter considers the relations between disability and the political in contemporary societies. This includes a discussion of possibilities of human agency and social movement capacities in the disability field. The analysis discusses several models of disability and statuses of bodies, which are evident in theory, movement advocacy, and public policy. These are the personal tragedy and worthy poor model, the biomedical model, the social model, the human rights model, and the psychoemotional model of disability. The chapter then examines activism as a repertoire of activities and roles taking place in various jurisdictional spaces and territorial scales of mobilization. The chapter next analyzes three forms of social injustices and advocacy strategies pursued by contemporary disability rights movements: activism centered on recognition, redistribution, and representation. Concluding observations call on the need to examine disability and the struggle for social justice in relation to a politics of cultural recognition and identity, a politics of socioeconomic redistribution of material goods and services, and a politics of democratic representation that combines conventional and alternative modes of decision-making. Over time, the mix and style of activism may shift at the level of the individual or family, the agency or movement organization, or the national and international sectors. This gives disability activism and the struggle for social justice dynamic qualities enacted through symbolic, materialist, and political concerns in interaction with public and private authorities.
Contextualizing Disability Experiences
Authors: Latham-Mintus Kenzie , Cordon Sabrina
Published: November 2021

Scholars and advocates have long proposed that an individual’s impairment is not the source of disability, but instead it is social and physical barriers put in place by society that are disabling. The purpose of this chapter is to (1) provide an overview of how contextual factors are conceptualized and measured in the current literature; (2) describe the key findings and discuss what the current research tells us about the salience of the environment for individual disability experiences; and (3) identify critical gaps in the literature and discuss future recommendations. The chapter takes a place-based approach and focuses on the communities and neighborhoods in which people with disabilities live. The chapter also explores how the intersection of disability and other social identities is influenced by the environment. Finally, the chapter concludes by discussing existing gaps in the literature and recommendations for future research.
Health system perspectives in acute kidney injury: commitment to kidney health and planning implementation interventions
Authors: Kane-Gill Sandra L.
Published: November 2021

Purpose of review

To discuss a deliberate commitment by health systems to optimize kidney health and outcomes of patients who are at risk for or develop acute kidney injury (AKI) during hospitalization.

Recent findings

In 2019, the US Department of Health and Human Services set national goals targeted at improving the care and outcomes of patients with kidney disease including prevention by reducing the number of Americans who develop end-stage kidney disease (ESKD) by 25% by 2030. In response to this call to action, there is a need to focus on education to identify patients at high-risk for kidney disease development and progression, active surveillance methods to ensure timely identification, offering better follow-up care after an episode of AKI. A strategic approach to determining the health systems level of commitment and developing a plan for organizational change is discussed in this commentary. Items for consideration are structuring sound implementation projects and selecting implementation interventions. Clinical interventions to consider for implementation include the use of clinical decision support for detecting patients with AKI, novel biomarkers to determine patients at high-risk for AKI and nephrotoxin stewardship to prevent medication safety complications and drug-associated AKI.

There is a national call to action to improve the care and outcomes of patients with kidney disease. Health systems have an opportunity to respond by providing a high level of commitment towards ensuring the best kidney health for all patients equally. Deliberate change that is sustainable and scalable should be considered by all health systems.
Above and beyond cancer: a novel approach to growth and resilience in cancer survivors
Authors: Vélez-Bermúdez Miriam , Norton Aleisha , Ament Natalie , Armer Jessica , Davis Lauren Z. , Deming Richard L. , Lutgendorf Susan K.
Published: November 2021

Background:

Although cancer diagnosis and treatment frequently cause distress, many survivors report personal growth, change, and transformation. To better understand these dynamics, we used a qualitative approach to study twenty-seven heterogeneous cancer survivors who participated in physically and emotionally challenging journeys through the Above and Beyond Cancer organization. Groups traveled to Kathmandu (Nepal), Mt. Kilimanjaro (Tanzania), and Mt. Kailash (China), and volunteered at nearby cancer hospitals.

Methods:

Survivors completed short essays and surveys pre-departure, 3 weeks, and 3 months post-trip. Qualitative responses were categorized into themes by 4 independent reviewers following consensus, and quantitative measures assessed sociodemographic characteristics and mood.

Results:

Qualitative findings highlighted the role of new experiences and social support in enabling participants to develop new meaning, growth, and a new sense of their capabilities. Quantitative measures showed that anxiety of participants decreased over time.

Conclusions:

This study points to lifestyle undertakings that can support personal growth in cancer survivors.

Freshwater systems are experiencing rapid biodiversity losses resulting from high rates of habitat degradation. Ecological condition is typically determined through identifying either macroinvertebrate or diatom bioindicator assemblages and comparing them to their known tolerance to stressors. These comparisons are typically conducted at family or genus levels depending on the availability of taxonomic keys and expertise for focal groups. The objective of this study was to test whether a more taxonomically comprehensive assessment of communities in benthic samples can provide a different perspective of ecological conditions. DNA metabarcoding was used to identify macroinvertebrates and diatoms from kick-net samples collected from sites with different habitat status. Sites with ‘good’ condition were associated with higher beta diversity as well as slightly higher directed connectance and modularity indicating higher resilience compared with ‘fair’ condition sites. Indicator value and correlation analyses used DNA metabarcoding data to detect 29 site condition indicator species consistent with known bioindicators and expected relative tolerances. DNA metabarcoding and trophic network analysis also recovered 11 keystone taxa. This study demonstrates the importance of taxonomic breadth across trophic levels for generating biotic data to study ecosystem status, with the potential to scale-up ecological assessments of freshwater condition, trophic stability, and resilience.
The Something About Silencing protein, Sas3, is the catalytic subunit of NuA3, a yTAFII30-containing HAT complex that interacts with the Spt16 subunit of the yeast CP (Cdc68/Pob3)–FACT complex

We have purified and characterized a Gcn5-independent nucleosomal histone H3 HAT complex, NuA3 (NucleosomalAcetyltransferase of histone H3). Peptide sequencing of proteins from the purified NuA3 complex identified Sas3 as the catalytic HAT subunit of the complex. Sas3 is the yeast homolog of the human MOZ oncogene. Sas3 is required for both the HAT activity and the integrity of the NuA3 complex. In addition, NuA3 contains the TBP- associated factor, yTAFII30, which is also a component of the TFIID, TFIIF, and SWI/SNF complexes. Sas3 mediates interaction of the NuA3 complex with Spt16 both in vivo and in vitro. Spt16 functions as a component of the yeast CP (Cdc68/Pob3) and mammalian FACT (facilitateschromatin transcription) complexes, which are involved in transcription elongation and DNA replication. This interaction suggests that the NuA3 complex might function in concert with FACT–CP to stimulate transcription or replication elongation through nucleosomes by providing a coupled acetyltransferase activity.

Thedaf-12gene acts at the convergence of pathways regulating larval diapause, developmental age, and adult longevity inCaenorhabditis elegans. It encodes a nuclear receptor most closely related to twoC. elegansreceptors, NHR-8 and NHR-48,DrosophilaDHR96, and vertebrate vitamin D and pregnane-X receptors.daf-12has three predicted protein isoforms, two of which contain DNA- and ligand-binding domains, and one of which contains the ligand-binding domain only. Mutations cluster in DNA- and ligand-binding domains, but correspond to distinct phenotypic classes. DAF-12 is expressed widely in target tissues from embryo to adult, but is upregulated during midlarval stages. In the adult, expression persists in nervous system and somatic gonad, two tissues that regulate adult longevity. We propose that DAF-12 integrates hormonal signals in cellular targets to coordinate major life history traits.

Regulators of G protein signaling (RGS proteins) inhibit heterotrimeric G protein signaling by activating G protein GTPase activity. Many mammalian RGS proteins are expressed in the brain and can act in vitro on the neural G protein Go, but the biological purpose of this multiplicity of regulators is not clear. We have analyzed all 13 RGS genes in Caenorhabditis elegans and found that three of them influence the aspect of egg-laying behavior controlled by Go signaling. A previously studied RGS protein, EGL-10, affects egg laying under all conditions tested. The other two RGS proteins, RGS-1 and RGS-2, act as Go GTPase activators in vitro but, unlike EGL-10, they do not strongly affect egg laying when worms are allowed to feed constantly. However, rgs-1; rgs-2double mutants fail to rapidly induce egg-laying behavior when refed after starvation. Thus EGL-10 sets baseline levels of signaling, while RGS-1 and RGS-2 appear to redundantly alter signaling to cause appropriate behavioral responses to food.

The chicken lysozyme locus is activated in a stepwise fashion during myeloid differentiation. We have used this locus as a model to study at high resolution changes in chromatin structure both in chicken cell lines representing various stages of macrophage differentiation and in primary cells from transgenic mice. In this study we have addressed the question of whether chromatin rearrangements can be detected in myeloid precursor cells at a stage well before overt transcription of the lysozyme gene begins. In addition to restriction enzyme accessibility assays and DMS footprinting, we have applied new, very sensitive techniques to assay for chromatin changes. Particularly informative was UV photofootprinting, using terminal transferase-dependent PCR and nonradioactive detection. We find that the basic chromatin structure in lysozyme nonexpressing hematopoietic precursor cells is highly similar to the pattern found in fully differentiated lysozyme-expressing cells. In addition, we find that only in nonexpressing cells are dimethylsulfate footprints and UV photofootprints affected by trichostatin, an inhibitor of histone deacetylation. These results are interpreted to mean that most chromatin pattern formation is complete before the binding of end-stage trans-activators, supporting the notion that heritable chromatin structure is central to the stable epigenetic programs that guide development.
