Data and scripts from: Mechanistic and scale-specific analyses advance the preference-performance hypothesis
No full textPlease cite as: Slimon, K. F., McArt, S., Salminen, J.-P., & Agrawal, A. (2025). Data and scripts from: Mechanistic and scale-specific analyses advance the preference-performance hypothesis [Data set]. Cornell University Library eCommons Repository. https://doi.org/10.7298/N064-NE73These files contain data and script supporting all results reported in "Mechanistic and scale-specific analyses advance the preference-performance hypothesis". In Slimon et al. we used the specialist seed predator moth Schinia florida and the common evening primrose Oenothera biennis, to investigate the mechanistic drivers of preference and performance and how these dynamics shift across scales, between- versus within-plants. We measured a suite of 126 plant traits, most of which were plant specialized metabolites captured by ultra-high performance liquid chromatography and mass spectrometry, and applied a novel machine learning approach to identify traits that predict both preference and performance. Between-plants, we found no relationship between preference and performance. However, nine overlapping plant traits predicted both preference and performance, with all traits positively correlated with preference showing a negative association with performance. This negative trait-based preference-performance link may result from trade-offs of moths using plant defenses as host finding cues. Overall, weak correlations between the nine predictive traits appear to limit a link between preference and performance between plants. Within plants, moths disproportionally oviposited on flower buds over fruits and concordantly showed higher relative performance on buds. At this scale, only two overlapping traits predicted both preference and performance, and both showed positive associations with preference and performance. Thus, our results show that 1) a specialist herbivore faces trait-based trade-offs between host-selection among plants and larval performance, while making more adaptive decisions at finer scales within plants, and 2) mechanistic and cross-scale approaches offer insight into when adult preference predicts larval performance.This work was supported, in part, by grants from the USA National Science Foundation (Integrative Organismal

Adaptive nutrient management makes sense!
No full textHave you ever wondered if more fertilizer could have given you higher corn yields? Most dairy farmers would reply with a solid yes, as it is a given that corn needs nitrogen (N) to grow and yield can vary quite a bit from field to field and year to year. However, how do you follow the rules and regulations of a Concentrated Animal Feeding Operation (CAFO) permit while managing the risk of making sure you have enough without applying too much and wasting money? And, how can we become more confident with making management changes? The Adaptive Nitrogen Management process, now in place in New York, addresses such challenging situations. The process allows N application with manure or fertilizer to exceed the foundational land-grant university (Cornell) guidelines on a field-by-field basis, if combined with yield data collection and the implementation of an end-of-season evaluation. Appropriate adjustments need to be made in the following year(s) if it turns out that the higher rates did not result in higher yields. In other words, the freedom to experiment with the responsibility to evaluate if the higher rate was warranted.This issue of The Manager is published by Progressive Dairy and printing is sponsored by Papillon
Making sense of your dairy's greenhouse gas footprint
No full textSome dairy farm teams are working with their milk coop , processor or advisor to develop a greenhouse gas (GHG) or "carbon" footprint. The footprint includes a GHG intensity score (emissions per unit of fat and crude protein-corrected milk) and an estimate of total GHG emissions (total emissions for the farm). What do these numbers mean and how can you make decisions based on the results of footprinting tools currently on the market? We believe that every dairy farm can benefit from developing a GHG footprint. Annual footprinting will help farmers keep their dairy business current as value chains increasingly ask for this information.This issue of The Manager is published by Progressive Dairy and printing is sponsored by Papillon
Prediction of corn silage whole plant moisture in the field
No full textNearly half of the corn acreage in New York state is harvested as corn silage. The correct crop moisture content is critical for nutritional value and proper ensiling. Visual estimation of plant moisture is problematic, based on visual assessment of stover, or on kernel milkline. Moisture content of stover changes very little until after the optimum harvest time for corn silage. Ear moisture is the primary driver of whole plant moisture content. The old rule of one-half milkline has been mostly replaced by two-thirds to three-quarters milkline, but milkline is still not necessarily well related to whole plant moisture. Our overall goal is to be able to accurately predict whole plant moisture in the field.This issue of The Manager is published by Progressive Dairy and printing is sponsored by Papillon
A Lens of Labour and Hyper-Agency; New Perspectives on Young People’s Involvement in Gangs and Organised Crime
No full textThis paper introduces two novel conceptual approaches to understanding young people’s participation in gangs and organised crime. The first, a “labour lens”, is informed by empirical research conducted in three Asian contexts—Bangladesh, China, and Nepal. This framework considers instrumental motivations underpinning involvement in crime, including children’s need to work for survival, moral economies, and the ecological conditions shaped by crime and legacies of colonialism. The second concept, “hyper-agency”, is derived from UK-based research with young people involved in county lines drug distribution. This research suggests that the forms of agency exercised within county lines are strategic yet ambivalent, oriented towards income generation, social belonging, and inclusion. The paper contends that this agency must be understood as context-specific, situated within broader dynamics of hyper-consumerism, digitally mediated lives, and intensified social realities. Thus, involvement in county lines reflects a distinct form of agency – a hyper-agency. The paper concludes by examining points of convergence and divergence across these concepts, empirical settings, and geographical locations, and by raising critical questions for global theorisation of young people’s engagement in gangs and organised crime
Perspective of Meaning: Drawing ‘out’ the allegorical stories of and in the National Portrait Gallery, London, UK
No full textThis discussion focuses on two drawings that were utilised to procure planning permission for alterations to the 1896 Gallery. The construction drawing is a conservation instruction for the preservation of existing windows beneath the new walls while the other employs allegory to present the roofscape of Trafalgar Square as an imagined Tuscan landscape, as a mode of persuasion to planning objections.
These original drawings translated architectural ideas at vastly different stages and were necessary for the new building to be realised. This approach to understanding the architecture of the Gallery continues from a history of narrative techniques underpinned by theoretical understandings concerning the notions of ‘perspective of meaning’, employed to address the meaning of the work. This is applied to critically evaluate the material, spatial, social and cultural aspects of the architecture. Hence these drawings are not isolated pieces of work but embedded within the history of the Gallery and in particular, the layers of meaning that are apparent.
This paper explores critical and reflective drawing practices in design through questioning assumptions of architecture as static and complete entities. Archival research through drawings reveals the design strategies adopted and the consequent response of each shift to specific situations. These notions of sites within sites advocate for the intertwined architectural narratives to be further devised as dialogues with users to enhance the reading, meaning and experiential qualities of the Gallery. The drawings serve to confront, place and integrate chronological shifts to initiate the notion of multiple interpretations, furthered as means to mediate and reinterpret research and design processes. Architectural drawings as historical markers and catalysts for transformation are further employed to interpret buildings and spatially reinterpret research material. Consequently, events that would otherwise be consigned to memory or totally forgotten are retold and given new readings and meanings through these drawings
Making Freelance Work
No full textOver 80% of practitioners in the UK arts sector work on a freelance basis. While freelancing offers scope for autonomy and creative freedom, it is also characterized by widespread precarity, low pay, long hours and systemic inequalities. Funding cuts and recent challenges have only intensified these conditions.
This book provides an evidence-based account of what it means to work as a freelancer in the UK performing arts sector, drawing on data from the Big Freelancer Survey (2020–2025). It presents a unique insight into arts-based freelance work in the UK, providing workable recommendations for change
