Knowledge of ancient trees and tree-forms helps inform understanding of landscape continuity and change. Information analysis of tree-form and growth rates may be combined with precise aging through dendro-chronology and carbon dating. Until recently, much of the information has been neglected, and indeed, there was an absence of accepted methodologies. Assessments of both coppice trees and pollards, for example, now suggest that trees achieve great age (for example, 500 years+ to 1500 years or more). These trees reflect both natural processes and human management. Examined within a robust conceptual and analytical framework, these trees generate insight into landscape evolution over centuries. Tree analysis combined with archival sources and site archaeological information, including mapping of ‘botanical indicator species’, soils, and other sediments, generate reliable timelines of human–environment interactions. Drawing together diverse approaches and insights into landscape evolution helps the formulation of new concepts of historical ecology and environmental history. Importantly, such emerging paradigms trigger new ways to demonstrate how understanding past landscape evolution both informs knowledge of contemporary ecologies and may guide future site planning. However, there is a rider to these observations since case studies in Great Britain highlight the vulnerability of such historic landscapes and show how they are being rapidly erased from the countryside.

This article analyses the Corbyn programme as an “observatory of social relations” between actors from across the British Left. We adopt a conception of party programmes inspired by French political sociology, as the product of the link between organisational spaces, social actors and competing political horizons. This has been done by mobilising a wider, decentred programmatic corpus as well as by analysing interviews with the actors involved. It demonstrates that the programme articulates tensions running through the milieu of Corbynism around different horizons of ownership, of redistribution and of ecological transition. These can be viewed as conjunctural, specific expressions of the tension between the “traditional” and “experimental” conceptions of socialism carried by the different social actors in question: trade unions, social movements and think tanks.

Since 2016, the fall armyworm (FAW) Spodoptera frugiperda has spread over extensive areas of the tropics and subtropics, imperiling food security, economic progress and the livelihoods of millions of cereal farmers. Although FAW has received long-standing scientific attention in its home range in the Americas, chemical inputs feature prominently in its mitigation and biological control uptake is globally lagging. Here, building upon a quantitative review of the global literature, we methodically dissect FAW biological control science. Of the known entomopathogens (46), parasitoids (304) and predators (215) of FAW, approx. 40% have been subject to laboratory- or field-level scrutiny. Laboratory-level performance has partially been assessed for 14–18% of the above invertebrate taxa. Yet, organismal, geographic, methodological and thematic biases hamper efforts to relate in-field biodiversity to actual ecosystem service delivery. Often, single-guild ‘snapshot’ surveys are preferred over comprehensive bio-inventories or population dynamics appraisals, trophic interactions are wrongly inferred from co-occurrence, standard pest infestation metrics are lacking and natural enemy censuses are performed arbitrarily. Diurnal biota receive inordinate attention, while egg and pupal predation - the main biotic sources of mortality - are routinely overlooked. Multiple microbial and invertebrate biota are investigated with a view towards mass-rearing and augmentative release, but the basis for agent selection is often unclear. Lastly, conservation biological control receives marginal attention and cross-disciplinary engagement with the agroecology domain is lagging. We lay out several steps, including standardized methodologies, smart use of biodemographic toolkits, networked field trials and a fortification of its ecological underpinnings, to sharpen the science of (FAW) biological control and urge further momentum in its global implementation.

Science is about facts and truth. Yet sometimes the truth and facts are not obvious. For example, in the field of MRI (Magnetic Resonance Imaging), there has been a long-lasting debate about who were the major contributors in its development. Particularly, there was a strong dispute between the followers of two scientists, R. Damadian and P. Lauterbur. In this review, we carefully trace the major developments in applying NMR for cancer detection starting almost 50 years ago. The research records show that the truth was beyond the claims of either research camps. The development of NMR for cancer detection involved multiple research groups, who made critical contributions at different junctures.

In the theoretical study of distributed communication networks, "history trees" are a discrete structure that naturally models the concept that anonymous agents become distinguishable upon receiving different sets of messages from neighboring agents. By conveniently organizing temporal information in a systematic manner, history trees have been instrumental in the development of optimal deterministic algorithms for networks that are both anonymous and dynamically evolving. This note provides an accessible introduction to history trees, drawing comparisons with more traditional structures found in existing literature and reviewing the latest advancements in the applications of history trees, especially within dynamic networks. Furthermore, it expands the theoretical framework of history trees in new directions, also highlighting several open problems for further investigation.

This paper presents GReAT (Graph Regularized Adversarial Training), a novel regularization method designed to enhance the robust classification performance of deep learning models. Adversarial examples, characterized by subtle perturbations that can mislead models, pose a significant challenge in machine learning. Although adversarial training is effective in defending against such attacks, it often overlooks the underlying data structure. In response, GReAT integrates graph based regularization into the adversarial training process, leveraging the data's inherent structure to enhance model robustness. By incorporating graph information during training, GReAT defends against adversarial attacks and improves generalization to unseen data. Extensive evaluations on benchmark datasets demonstrate that GReAT outperforms state of the art methods in robustness, achieving notable improvements in classification accuracy. Specifically, compared to the second best methods, GReAT achieves a performance increase of approximately 4.87% for CIFAR10 against FGSM attack and 10.57% for SVHN against FGSM attack. Additionally, for CIFAR10, GReAT demonstrates a performance increase of approximately 11.05% against PGD attack, and for SVHN, a 5.54% increase against PGD attack. This paper provides detailed insights into the proposed methodology, including numerical results and comparisons with existing approaches, highlighting the significant impact of GReAT in advancing the performance of deep learning models.

With the evolution of pre-trained language models, current open-domain dialogue systems have achieved great progress in conducting one-session conversations. In contrast, Multi-Session Conversation (MSC), which consists of multiple sessions over a long term with the same user, is under-investigated. In this paper, we propose History-Aware Hierarchical Transformer (HAHT) for multi-session open-domain dialogue. HAHT maintains a long-term memory of history conversations and utilizes history information to understand current conversation context and generate well-informed and context-relevant responses. Specifically, HAHT first encodes history conversation sessions hierarchically into a history memory. Then, HAHT leverages historical information to facilitate the understanding of the current conversation context by encoding the history memory together with the current context with attention-based mechanisms. Finally, to explicitly utilize historical information, HAHT uses a history-aware response generator that switches between a generic vocabulary and a history-aware vocabulary. Experimental results on a large-scale MSC dataset suggest that the proposed HAHT model consistently outperforms baseline models. Human evaluation results support that HAHT generates more human-like, context-relevant and history-relevant responses than baseline models.

I apply Dawid's Meta-Empirical Assessment (MEA) methodology to the theory of cosmological inflation. I argue that applying this methodology does not currently offer a compelling case for ascribing non-empirical confirmation to cosmological inflation. In particular, I argue that despite displaying strong instances of Unexpected Explanatory Coherence (UEA), it is premature to evaluate the theory on the basis of the No Alternatives Argument (NAA). More significantly though, I argue that the theory of cosmological inflation fails to sustain a convincing Meta-Inductive Argument (MIA) because the empirical evidence and theoretical successes that it seeks to draw meta-empirical support from do not warrant a meta-inductive inference to inflation. I conclude by assessing how future developments could pave the way towards crafting a more compelling case for the non-empirical confirmation of cosmological inflation.

The Great Gatsby Curve measures the relationship between income inequality and intergenerational income persistence. By utilizing genealogical data of over 245,000 mentor-mentee pairs and their academic publications from 22 different disciplines, this study demonstrates that an academic Great Gatsby Curve exists as well, in the form of a positive correlation between academic impact inequality and the persistence of impact across academic generations. We also provide a detailed breakdown of academic persistence, showing that the correlation between the impact of mentors and that of their mentees has increased over time, indicating an overall decrease in academic intergenerational mobility. We analyze such persistence across a variety of dimensions, including mentorship types, gender, and institutional prestige.

Based on string theory's framework, the gauge/gravity duality, also known as holography, has the ability to solve practical problems in low energy physical systems like metals and fluids. Holographic applications open a path for conversation and collaboration between the theory-driven, high energy culture of string theory and fields like nuclear and condensed matter physics, which in contrast place great emphasis on the empirical evidence that experiment provides. This paper takes a look at holography's history, from its roots in string theory to its present-day applications that are challenging the cultural identity of the field. I will focus on two of these applications: holographic QCD and holographic superconductivity, highlighting some of the (often incompatible) historical influences, motives, and epistemic values at play, as well as the subcultural shifts that help the collaborations work. The extent to which holographic research -- arguably string theory's most successful and prolific area -- must change its subcultural identity in order to function in fields outside of string theory reflects its changing nature and the field's uncertain future. Does string theory lose its identity in the low-energy applications that holography provides? Does holography still belong under string theory's umbrella, or is it destined to form new subcultures with each of its fields of application? I find that the answers to these questions are dynamic, interconnected, and highly dependent on string theory's relationship with its field of application. In some cases, holography can maintain the goals and values it inherited from string theory. In others, it instead adopts the goals and values of the field in which it is applied. These examples highlight a need for the STS community to expand its treatment of string theory beyond its relationship with empiricism and role as a theory of quantum gravity.

Chromatic dispersion is a common problem to degrade the system resolution in optical coherence tomography (OCT). This study is to develop a deep learning network for automated dispersion compensation (ADC-Net) in OCT. The ADC-Net is based on a redesigned UNet architecture which employs an encoder-decoder pipeline. The input section encompasses partially compensated OCT B-scans with individual retinal layers optimized. Corresponding output is a fully compensated OCT B-scans with all retinal layers optimized. Two numeric parameters, i.e., peak signal to noise ratio (PSNR) and structural similarity index metric computed at multiple scales (MS-SSIM), were used for objective assessment of the ADC-Net performance. Comparative analysis of training models, including single, three, five, seven and nine input channels were implemented. The five-input channels implementation was observed as the optimal mode for ADC-Net training to achieve robust dispersion compensation in OCT

Lee Dunne’s Goodbye to the Hill (1965) follows the life of Paddy Maguire in the Dublin suburb of Ranelagh during the mid-20th century. As a Bildungsroman, Dunne’s novel charts the rites of passage necessary for Maguire to take his place in society among his peers. An important rite of passage for Maguire is his entrance into Dublin pubs as a way of achieving the ideals of local hegemonic masculinity. J.P. Donleavy’s novel The Ginger Man (1955) then chronicles the psychological breakdown of the protagonist Sebastian Dangerfield. His breakdown is marked by frantic visits to public houses around Dublin where he seeks solace and a sense of re-masculinisation from his anxieties. This essay argues how Irish pubs are depicted in 20th century fiction as ideological vehicles charged with assimilating Irish men into the ranks of homosocial society, inculcating the ideals of local hegemonic masculinity. This essay also demonstrates how, as a space from which women were barred until the 1960s in Ireland, pubs were used as essential hubs for homosocial interaction and markers of Irish masculinity. When women were gradually allowed into pubs, their presence was often sanctioned with certain caveats, often conducive to regulating additional aspects of local hegemonic masculinity

The literary output that was produced during the rise of the British Empire often reflected the imperialist spirit that dominated the world at that time. Travel writing was one of the major fields which prospered in parallel with the spread of British global paramountcy. This literary genre contributed to strengthening and legitimising the imperialist and colonialist expansion and therefore represents one of the prominent samples for the postcolonial analytical framework. This paper will focus on one of these travel accounts, Seven Pillars of Wisdom: A Triumph (1935), written by Thomas Edward Lawrence also known as ‘Lawrence of Arabia’. Drawing upon postcolonial literary criticism, this paper will show the way Lawrence simultaneously reaffirms and rejects the imperialist and colonialist discourse in his portrayals. This paper will shed light on the ambivalence which prevails in Lawrence’s representations of the Orient. On the one hand, this research shows the way Lawrence showcases examples of imperialist thinking by reproducing stereotypical representations of the Orient through excessive aestheticisation or demeaning of Oriental people and landscapes. On the other hand, this paper highlights Lawrence’s departure from the conventional imperialist discourse with more nuanced portrayals. This paper contends that Lawrence’s Orientalist discourse is much more ambivalent and subtle than the conclusions elaborated by Edward Said in his critical theory of Orientalism.

Tackling health inequalities has become one of the key focuses of government health policy over recent years. Health inequalities refer to differences between people or groups due to social, geographical, biological or other factors in terms of life expectancy and healthy life expectancy According to the 2010 Marmot review, not only is there a strong social justice case for reducing health inequalities, but also an economic one, since it is estimated to cost over £30 billion a year in lost productivity and welfare costs. Health coverage is universal in England and close to full coverage in many areas of public health. The founding principles of the NHS are that public health services should be free at the point of use and that health inequalities are undesirable because they are unfair or unjust. Yet, despite universal coverage of health services and the equity principles behind public health in the UK, nowhere is the North-South divide more apparent than in the area of health. Since the 1960s, the South has consistently outperformed the North in terms of health outcomes in all areas (life expectancy, ill health, chronic disease…). Poor health is associated with socio-economic status, which is one of the main reasons why the North is at a disadvantage, with a higher number of neighbourhoods suffering from multiple deprivation. This paper considers health inequalities between the North and South and reviews policy implemented since the late 1970s to improve health service delivery in the North of England. In particular, it considers to what extent public policy has mitigated health inequities there.

The aim of this paper is to analyse the new perspectives on the locus amoenus put forward by contemporary women poets in Ireland, in particular those by the female authors included in the anthology Our Shared Japan, edited by Irene De Angelis and Joseph Woods (2007). This paper argues that these writers provide alternatives to traditional pastoralism that trigger new reflections on women’s identities and subjectivities. As Donna L. Potts asserts, some constitutive aspects of the pastoral tradition are “the relationship between nature and human nature, and between the present and the mythicised past, the motif of transformation, etc.” (9). These aspects will be scrutinised in the context of travel to the new, exotic space of Japan. The alterity that the poetic voices meet with in their travel provides them with new perceptions of themselves and their affective life in relation to the environment. This renegotiation of identity is mostly made through the body, which becomes a tool for knowledge and communication. The heterotopia (Foucault) of the trip, therefore, provides the perfect space for the poetic subjects to interact, change and reflect about their identity, their sense of belonging or alienation and the impact of travel on their emotional life.
