History and formation of “Limb Lengthening and Reconstruction Surgery - LLRS” as a subspecialty of orthopedic surgery

In the late 1970s, Italian orthopedic surgeons learned about the Ilizarov Method from patients who returned to Italy after being treated for serious motor scooter injuries sustained while vacationing in nearby communist Yugoslavia. Likewise, Carlo Mauri, a famous Italian explorer/writer went to Siberia to be personally treated by Dr. Ilizarov for a recalcitrant infected non-union of his tibia. Mauri’s return to his native land after a successful cure stimulated interest among Italian doctors.

Вопросы развития национального литературоведения и его понятийно-терминологического аппарата

The purpose of the research is to actualize the problem of formation of the conceptual and terminological apparatus of the Chuvash literary criticism in the national language. Since its inception (the late 1920s) Chuvash literary criticism has relied on advanced ideas, discoveries and concepts of Russian literary criticism. Chuvash researchers (except for P. N. Metin, A. I. Mefodiev - the authors of the "School Dictionary of Terms of Literary Criticism and Folkloristics") were not concerned with the systematization of their own concepts, which reflect the national characteristics of Chuvash literature. Today, the practice of using Russian-language terms in Chuvash literary criticism has been fixed even in cases when there are synonyms for them in the Chuvash language. The scientific novelty of the research is that it analyzes for the first time the basic methods of term formation in Chuvash literary criticism. Actualization of this issue in the Chuvash scientific community should contribute to the development of Chuvash literary criticism (more broadly - the entire philological science) in the field of national aesthetics. The results obtained showed that in Chuvash literary criticism the conceptual and terminological apparatus in the Chuvash language has not been fully formed, it is dominated by Russian-language terms that do not obey either phonetic or orthographic laws of the Chuvash language.

Why Do More People Commit Suicide after the Economic Bubble

This paper examines the relationship between the economic recession and the high suicidal rates in Japan during the post-economic bubble in the late 1990s and early 2000s. The aim of the study is to explore the relationship between the economic recession, mental health, suicide prevalence and sociocultural dynamics. The literature review and empirical analysis show compelling evidence linking economic instability, financial distress, and unemployment to increased suicide rates. In addition, this paper explores the interplay of cultural factors for instance, stigma surrounding mental health and collective norms, in explaining the vulnerability experienced by individuals during economic recessions and hard times. Key findings emphasize the role of economic stability in increasing vulnerabilities as well as the effects of unemployment, familial relationships and self-esteem. The findings also show that the societal pressure to adhere to traditional roles, especially in times of economic uncertainty, is a key stressor affecting mental well-being. The study advocates for detailed research strategies such as interviews and surveys to further investigate causal relationships. This research provides key insights into the varying factors that contribute to suicide during economic crises, suggesting the need for holistic interventions that address both sociocultural and economic dimensions.

A Systematized Review of Quantitative Ultrasound Based on First-Order Speckle Statistics.

Since the late 1970s, the speckle interference patterns ubiquitous in pulse-echo ultrasound images have been used to characterize sub-resolution tissue structure. During this time, new models, estimation methods, and processing techniques have proliferated, offering a wealth of recommendations for the task of tissue characterization. A literature review was performed to draw attention to these various methods and to critically track assumptions and gaps in knowledge. A total of 388 articles were collected from a systematic search for first-order speckle statistics in diagnostic ultrasound in the NIH PubMed database and Elsevier's Scopus database. Articles were grouped by basic characteristics and evaluated for addressing fundamental assumptions. A sampling of models and methods is presented in order to reveal the state of the art in speckle statistics as well as sources of measurement error and other important considerations. While this body of literature emphasizes the value of speckle analysis in diagnostic ultrasound, it is shown that relatively little attention is devoted to basic assumptions such as the linearity of system response and scatterer geometry. Additionally, several areas of investigation are available to improve upon speckle statistics analysis, potentially leading to the advancement of this unique tool.

Hydrogels in the clinic: An update

AbstractHydrogels have been used in the clinic since the late 1980s with broad applications in drug delivery, cosmetics, tissue regeneration, among many other areas. The past three decades have witnessed rapid advances in the fields of polymer chemistry, crosslinking approaches, and hydrogel fabrication methods, which have collectively brought many new hydrogel products, either injectable or non‐injectable, to clinical studies. In an article published in 2020 entitled “Hydrogels in the clinic”, we reviewed the clinical landscape and translational challenges of injectable hydrogels. Here, we provide an update on the advances in the field and also extend the scope to include non‐injectable hydrogels. We highlight recently approved hydrogel products, provide an update on the clinical trials of injectable hydrogels, and discuss active clinical trials of topically applied and implantable hydrogels.

From raw seismic data to quantitative interpretation via cloud-based FWI

Full-waveform inversion (FWI) has evolved in recent years from a technique for recovering long- to intermediate-wavelength updates of acoustic overburden velocities as part of a broader model building workflow to a standalone tool for high-fidelity seismic imaging using raw seismic data – with ever greater resolution and ever more sophisticated physics being sought. In doing so, it has moved notably closer to fulfilling the vision of its original inventors in the late 70s and early 80s. In this work, two novel approaches to FWI along with enabling technologies for their effective deployment are considered. The first of these allows for robust long-wavelength updates to be generated from raw seismic data in the absence of diving wave energy, providing reliable estimates of acoustic velocity at depths equivalent to or greater than the longest offsets available in the data – thereby enabling more effective imaging with data of limited quality. The second allows for the estimation of elastic amplitude-versus-angle behaviour while still using an acoustic wave equation, thereby mitigating the significant computational burden typically associated with elastic FWI. Finally, it is demonstrated that these approaches can be deployed in a reliable and cost-effective manner via the considered use of public cloud resources, with learnings relevant for analogous massively parallel scientific applications. Case studies from two marine environments are provided for discussion, one being from deep-water US Gulf of Mexico and the other from intermediate water depths offshore Western Australia.

The making of Holocaust education in Britain, 1945–1991

ABSTRACT Despite the prevalence of research in Holocaust memory and Holocaust education, the historical development of British Holocaust education remains understudied. This paper reconstructs this history, presenting Anglo-Jewish efforts to teach about the Holocaust in the 1970s for the first time and using the concept of ‘cosmopolitan memory’ to explain its proliferation in the early 1980s. This article argues that the origins of contemporary Holocaust education should not be found in the increase of its teaching with the National Curriculum of 1991 but in the changing culture of memory and history teaching in the late 1970s and early 1980s.

On the basis of sex: a liberal feminist analysis of women’s struggle for education

This study delves into the portrayal of women's struggles for education as depicted in the Hollywood film “On the Basis of Sex.” It seeks to address the pervasive influence of patriarchal dominance that impedes women's educational rights. The narrative is primarily framed around the life experiences of the film's central figure, Ruth Bader Ginsburg, who contends with male counterparts in her quest for admission to prestigious law school programs in the United States. Simultaneously, feminists advocate for education as a cornerstone for women's empowerment and gender equality. It empowers women to become agents of change, thereby emphasising their equal rights to shape a better world. The research adopts a qualitative approach, collecting both primary and secondary data, and employs liberal feminist critical theory for data analysis. Key findings reveal the disadvantaged state of American women in the late 1950s, marked by limited educational access. Despite these obstacles, women, exemplified by Ginsburg, displayed unwavering determination and unity in their pursuit of improved educational opportunities, subsequently expanding their presence in the legal profession and public employment. Ginsburg’s remarkable journey serves as an enduring symbol of resilience and inspiration for others, reaffirming the notion that education is a universal right transcending gender barrier.

Printing Ochre

The discipline of geology was relatively new at the start of the United States Geological Survey (USGS) in the late 1800s, but through the organisation of an efficient government bureau and the voice of its printed page, it became a dominant perspective in the way generations of citizens relate to and view the natural world, human and nonhuman, life and nonlife. I choose to position my press in direct opposition to the maintenance of these dualisms. I will argue the critical role of print in facilitating USGS domination of terrestrial beings in a practical sense, yet beyond the methods and reach of publication, I believe the products of the USGS mediate our understanding of and relation to these beings. Instead, design practices can be directed towards changing attitudes and understanding between humans and nonhumans. Monika Bakke argues for the importance of artistic endeavours in addressing our collective futurity: Drawing on both life’s mineral origins and its key role in shaping mineral species, artists are turning to technoscience in order to develop, outside expert circles, better understanding of physical, chemical, and biological environments, not just of the geological past but also those to come in the future. ... Yet, their methodologies are specific to art which offers creative ontological and ethical contributions to public debate. (2017, p. 43) I am developing a design research paradigm relating to ochre as an epistemic tool for human and nonhuman intersubjectivity and ontological reconciliation or reunification between life and nonlife. I model my practice after a simplification of the USGS: to survey (observe, describe, collect) and to report (archive, document, record), with some critical variance in method and outcomes.

Firearm and Criminal Milieu Homicide in Sweden

This study analyzes the trend in firearm and criminal milieu–related homicides in Sweden in the past three decades. A particular focus is on the 2010–2019 period, during which a dramatic increase was noted, although an increase in firearm homicides with illegal guns had already started in the late 1990s. In extant literature, the rapid increase in the 2010s is posited to be associated with fast access to illegal weapons, especially among youth in the most urban regions, Stockholm and Skaane County in particular. As a result, many victims and perpetrators are young men. This issue is proposed to be exacerbated by the new possibilities for organized crime setups in the wake of the digital revolution, a heightened level of social problems in the aftermath of high immigration from developing countries in combination with the dismantling of welfare institutions, and a self-increasing chain reaction of violence triggered by random episodes in the criminal milieu. These hypotheses are largely supported by this study’s findings.

Borrelia burgdorferi

Since its recent discovery in the late 1970s, Lyme Disease (LD) has been a growing public health concern, especially in the United States where it accounts for the majority of vector-borne infections each year. The causative agent, Borrelia burgdorferi, is transmitted to humans through the bite of an infected Ixodes tick. This pathogen uses many unique mechanisms to both shield itself from the host immune response and cause disease. Clinically, LD presents in successive phases, with each increasing in severity as the bacterial cells migrate to new tissues and organ systems. On the epidemiological and ecological fronts, limitations in reporting, ecological changes, and a lack of public support hinder accurate surveillance and enhance the spread of the disease. The goal of this literature review is to increase public knowledge of B. burgdorferi, its vector, and the disease it causes, along with suggesting preventative measures to protect individuals who reside in high-risk areas. A collective and coordinated public health effort represents our greatest chance of restraining the LD-causing pathogen.

Balloon drift estimation and improved position estimates for radiosondes

Abstract. When comparing model output with historical radiosonde observations, it is usually assumed that a radiosonde has risen exactly above its starting point and has not been displaced by wind. This changed only relatively recently with the availability of Global Navigation Satellite System (GNSS) receivers aboard radiosondes in the late 1990s, but even then the balloon trajectory data were often not transmitted, although this information was the basis for estimating the wind in the first place. Depending on the conditions and time of year, radiosondes can sometimes drift a few hundred kilometres, particularly at the middle latitudes during the winter months. The position errors can lead to non-negligible representation errors when the corresponding observations are assimilated. This paper presents a methodology to compute changes in the balloon position during its vertical ascent, using only limited information, such as the vertical profile of wind contained in the historical observation reports. The sensitivity of the method to various parameters is investigated, such as the vertical resolution of the input data, the assumption about the vertical ascent speed of the balloon, and the departure of the surface of Earth from a sphere. The paper considers modern GNSS sonde data reports for validation, for which the full trajectory of the balloon is available, alongside the reported wind. Evaluation is also conducted by comparison with ERA5 and by conducting low-resolution data assimilation experiments. Overall, the results indicate that the trajectory of the radiosondes can be accurately reconstructed from original data of varying vertical resolutions and that the more accurate balloon position reduces representation errors and, in some cases, systematic errors.

Changes in potential evaporation with the extension of water‐saving irrigation in Xinjiang, north‐western China

AbstractSince the late 1990s, the irrigation quota in Xinjiang, northwestern China has witnessed a decline, owing to the widespread adoption of highly efficient water‐saving irrigation technologies. This phenomenon prompts the question: has there been a corresponding impact on potential evaporation? To explore changes in potential evaporation resulting from irrigation advances, we conducted a comprehensive analysis spanning the years 1978–2017 in Xinjiang. Our investigation focused on a pairwise examination of agricultural stations with substantial irrigation effects, enveloped by a substantial proportion of cultivated land, and reference stations with negligible irrigation effects, surrounded by a comparatively smaller proportion of cultivated land. The findings unveiled a noteworthy reduction in potential evaporation at agricultural stations during the period 1978–1997. However, a contrasting trend emerged in the subsequent period of 1998–2017, wherein there was a significant increase in potential evaporation. In contrast, reference stations did not exhibit statistically significant reversals in potential evaporation. The observed changes in potential evaporation at agricultural stations were primarily attributed to shifts in aerodynamic components. These changes were closely associated with the reversed changes in irrigation intensity, a consequence of the widespread adoption of water‐saving irrigation practices since 1998.

Forests high on CO2: A glimpse into how scientists study the biochemical machinery of forest ecosystems

Are forests across the planet storing more carbon as a result of rising atmospheric carbon dioxide (CO2) concentration? In this text, I propose to reflect on the work of researchers who are asking that very question. The focus is on a particular approach called free-air CO2 enrichment (FACE) experiments, in which forests in their local environment are subjected to a CO2 concentration higher than in the ambient air, to test the CO2 fertilization hypothesis. This hypothesis predicts that forests store more carbon in those conditions. FACE studies held the promise of establishing cause–effect relations and transcending the here and now. They emerged in the United States in the late 1980s, at a time when ecology scaled up to make itself relevant to the then nascent Earth System science. FACE experiments in forests are now conducted in Australia, the United Kingdom, and Brazil, and their results are closely scrutinized by a small research community. The text, first, presents the engineering feat that underpins FACE experiments in forests and discuss two problems highlighted by scientists because they impede hasty generalization from the data: the timescale needed to witness forests change and the spatial heterogeneity of forest soils. It then shows how scientists contend with their incomplete understanding of forest ecosystems as they bring together computer models and empirical data to build consensus around the sources of epistemic uncertainty. To conclude, I propose to rework the idea of “the macroscope” to conceptualize what scientists do when they seek to study forests as complex, layered, multi-scale systems. I wish to capture how researchers, who willingly endorse a planetary gaze, problematize their own predicament. This, as I suggest, has to do with the immanence of forests in the world.

Shedding light on GPIbα shedding.

Ectodomain shedding has been investigated since the late 1980s. The abundant and platelet specific GPIbα receptor is cleaved by ADAM17 resulting in the release of its ectodomain called glycocalicin. This review will address the role of glycocalicin as an end-stage marker of platelet turnover and storage lesion and will consider a potential function as effector in processes beyond hemostasis. Glycocalicin has been described as a marker for platelet senescence, turnover and storage lesion but is not routinely used in a clinical setting because its diagnostic value is nondiscriminatory. Inhibition of glycocalicin shedding improves posttransfusion recovery but little is known (yet) about potential hemostatic improvements. In physiological settings, GPIbα shedding is restricted to the intracellular GPIbα receptor subpopulation suggesting a role for shedding or glycocalicin beyond hemostasis. So far, all evidence represents glycocalicin as an end-stage biomarker of platelet senescence and a potential trigger for platelet clearance. The extensive list of interaction partners of GPIbα in fields beyond hemostasis opens new possibilities to investigate specific effector functions of glycocalicin.

Cultural globalization at sea: the rise of the modern Caribbean cruise industry

ABSTRACT Carnival, Royal Caribbean, and Norwegian—the largest cruise lines today—emerged in the late 1960s and early 1970s, advertising their packaged vacations to a growing audience of middle-class Americans interested in encountering cultural difference. This article argues that, beginning in the late 1970s and continuing into the following decade, the cultural representations that these mass-market companies leveraged drew on Eurocentric understandings of Caribbean societies, homogenizing those countries despite attempts to showcase difference. These companies also reimagined global cultures Eurocentrically in onboard themed experiences. As both a product and agent of globalization, the mass-market cruise industry selectively deployed referents in ways that increased the appeal of cruising as escapism while reducing the likelihood of cultural confusion and reassuring passengers of their comfort. Through these processes, companies produced cruise ships as metaspaces while simultaneously expanding the construction of metaspaces to ports as they gained economic and political power in the Caribbean. This process resulted in the erasure of cultural difference.

Oceanographic Research in the Thermaikos Gulf: A Review over Five Decades

The Thermaikos Gulf (TG) is a semi-enclosed, river-influenced, marine system situated in the eastern Mediterranean Sea, sustaining both urban coastal regions and ecologically preserved natural areas. Facing a plethora of environmental and anthropogenic pressures, the TG serves as a critical nexus where human activities intersect with marine ecosystems. The quality and health of the TG’s marine environment are tightly linked to the socioeconomic activities of the coastal communities comprising approximately 1.5 million inhabitants. The main features of the TG’s environmental dynamics and ecological status have been scrutinized by dedicated research endeavors during the last 50 years. This review synthesizes the seminal findings of these investigations, offering an evaluation of their contribution to research, their present collective impact, and their trajectory toward the future. A severe deterioration of the TG’s environmental quality was detected in the 1970s and 1980s when the treatment of urban wastewater was completely absent. A steady trend of recovery was observed after the 1990s; however, so far, the goal of a “good environmental state” mandated by national legislation and European directives has not been achieved. A clear reduction in research was detected after 2010, associated with the recession of the Greek economy, following the “golden period” for research in the TG from the mid-1990s until the late 2000s. The most important research gaps and uncertainties are discussed, while specific targeted recommendations for the improvement of monitoring and understanding of the physical, biochemical, and ecological state of the gulf are provided: (i) increase in permanent observational stations (temporally and spatially); (ii) inclusion of all major environmental parameters; (iii) monitoring of the quantity and quality of all land-originated freshwater discharges; (iv) monitoring and management of important aspects of the marine environment that have received minimal attention in the past (e.g., coastal erosion, plastic pollution); (v) development of accurate prediction tools (e.g., numerical techniques) to support first-level responders and efficient management; (vi) establishment of a supervising public entity that would support the holistic overview and management of the entire TG. These suggestions are directed at overcoming the existing uncertainties in the knowledge of the TG, safeguarding its ecological integrity and its role as a crucial link to marine biodiversity and sustainability in the Mediterranean basin.

This introduction provides a brief personal background and highlights the scientific accomplishments of Professor Christopher Tam. He has maintained extremely high standards of research and an enviable track record for productivity, spanning more than five decades. The depth and breadth of his technical output are truly breathtaking, and he has inspired scores of researchers and graduate students. When the first author was an Acoustics Engineer at Lockheed, Georgia, he started collaborating with Chris in the early 1990s. There were several joint projects when the author moved to Boeing, which encompassed both fundamental research and applications. The second author has an even longer association with Chris, initially as a PhD advisee in the late 1980s and then as a co-researcher. In this special volume we pay tribute to Chris’s many achievements, an endeavor that provides us with great satisfaction and which is long overdue.

‘It won’t be the witches that are burning this time’: The anarchist temporalities of folk punk

This article is an exploration of the temporal politics of folk punk. Folk punk is a subgenre of punk played with predominantly acoustic instruments that emerged in the 1980s but developed a more concrete form in the late 1990s. This article compares the temporal politics of two scenes within folk punk. First, it looks at an early scene centred on the record label Plan-It-X. Second, ‘traditional folk punk’ is examined. In this latter scene, artists utilize an increasing range of instruments and musical resources associated with various types of traditional music. This musical change is also reflected lyrically; the second scene has much broader temporal references in comparison with the narrowly defined presentism of the Plan-It-X scene. The central argument of this article is that these musical and lyrical differences are politically and theoretically important. The dynamics within the folk punk scene complicate understandings of prefigurative politics, challenging the forms of presentism and individualism that this concept is associated with. The implications of these dynamics are lastly elaborated upon with reference to Gustav Landauer’s mystical anarchism.

Surface Topography Induces and Orients Nematic Swarms of Active Filaments: Considerations for Lab-On-A-Chip Devices.

Surface-bound molecular motors can drive the collective motion of cytoskeletal filaments in the form of nematic bands and polar flocks in reconstituted gliding assays. Although these "swarming transitions" are an emergent property of active filament collisions, they can be controlled and guided by tuning the surface chemistry or topography of the substrate. To date, the impact of surface topography on collective motion in active nematics is only partially understood, with most experimental studies focusing on the escape of a single filament from etched channels. Since the late 1990s, significant progress has been made to utilize the nonequilibrium properties of active filaments and create a range of functional nanodevices relevant to biosensing and parallel computation; however, the complexity of these swarming transitions presents a challenge when attempting to increase filament surface concentrations. In this work, we etch shallow, linear trenches into glass substrates to induce the formation of swarming nematic bands and investigate the mechanisms by which surface topography regulates the two-dimensional (2D) collective motion of driven filamentous actin (F-actin). We demonstrate that nematic swarms only appear at intermediate trench spacings and vanish if the trenches are made too narrow, wide, or tortuous. To rationalize these results, we simulate the F-actin as self-propelled, semiflexible chains subject to a soft, spatially modulated potential that encodes the energetic cost of bending a filament along the edge of a trench. In our model, we hypothesize that an individual filament experiences a penalty when its projected end-to-end distance is smaller than the trench spacing ("bending and turning"). However, chains that span the channel width glide above the trenches in a force- and torque-free manner ("crowd-surfing"). Our simulations demonstrate that collections of filaments form nematic bands only at intermediate trench spacings, consistent with our experimental findings.
