Harnessing Large-Scale Herbarium Image Datasets Through Representation Learning

The mobilization of large-scale datasets of specimen images and metadata through herbarium digitization provide a rich environment for the application and development of machine learning techniques. However, limited access to computational resources and uneven progress in digitization, especially for small herbaria, still present barriers to the wide adoption of these new technologies. Using deep learning to extract representations of herbarium specimens useful for a wide variety of applications, so-called “representation learning,” could help remove these barriers. Despite its recent popularity for camera trap and natural world images, representation learning is not yet as popular for herbarium specimen images. We investigated the potential of representation learning with specimen images by building three neural networks using a publicly available dataset of over 2 million specimen images spanning multiple continents and institutions. We compared the extracted representations and tested their performance in application tasks relevant to research carried out with herbarium specimens. We found a triplet network, a type of neural network that learns distances between images, produced representations that transferred the best across all applications investigated. Our results demonstrate that it is possible to learn representations of specimen images useful in different applications, and we identify some further steps that we believe are necessary for representation learning to harness the rich information held in the worlds’ herbaria.

Descartes on fermentation in digestion: iatromechanism, analogy and teleology

Fermentation is a cornerstone phenomenon in Cartesian physiology, accounting for processes such as digestion or blood formation. I argue that the previously unrecognized conceptual tension between the terms ‘fermentation’ and ‘concoction’ reflects Descartes's efforts towards a novel, more thoroughly mechanistic theory of physiology, set up against both Galenism and chymistry. Similarities with chymistry as regards fermentation turn out either epistemologically superficial, or based on shared earlier sources. Descartes tentatively employs ‘fermentation’ as a less teleological alternative to ‘concoction’, later renouncing the explicit use of the term, possibly to avoid chymical overtones. However, his continued use of analogies with fermentative processes in the natural world and in winemaking, coupled with a strong ontological commitment (the stance that the physiological processes are actual fermentations), leads to a reintroduction of natural teleology in his medical system, which I argue may be understood in an Aristotelian sense of ‘simple necessity’. The paper reveals a more nuanced account of Cartesian fermentative medicine, delineating some of its tensions with regard to chymistry as they play out in the dynamics of fermentation and concoction, and linking the analogies to fermentation processes to the difficulties in erasing teleology altogether.

Adventure sports, risk, and human-more than human wellbeing: local responses to the challenges of the COVID-19 pandemic

The impact of, and responses to COVID-19 has dominated discussion in every area of life, and fields of academic activity. In this paper I consider some of the impacts and considerations in relation to activities that have been conceptualised as adventure sports. My intention is not to show how adventure is being done differently, rather to use the exceptional circumstances of lockdown to highlighted the multifaceted, meaningful and affective ‘everyday’ experiences of those who engage in adventure sport as part of their everyday practices. My focus is empirical research conducted in Aotearoa New Zealand during lockdowns (2020-21) focusing on coastal communities and surfing specifically. This ‘journey through lockdown’ illustrates the ways in which coastal spaces are experienced as therapeutic landscapes that can foster physical and emotional health and wellbeing from those on the shore, to full-immersion activities such as surfing, influencing people’s sense of wellbeing, collective identities, and forms of belonging. However, in the same ways that COVID has exacerbated many health inequities, it is important to be attentive to the ways in which the wellbeing benefits of coastal spaces are not available and extended to all. A range of cultural, economic, socio-demographic, and political factors contribute to a dis-connect with, or exclusion from various bluespaces. Diverse subjects and bodies access and experience bluespaces in different and unequal ways, impacting who can use blue spaces, and how it can be used. Lastly, the lockdown situation was also informing in understanding the often-romanticised nature of adventure sport participants relationship with the natural world, and more widely how this translates, or not, to broader responses to our climate emergency.

Rethinking the Methodological Foundation of Historical Political Science

The basis of a methodology determines whether a research method can fit the core characteristics of a particular academic tradition, and thus, it is crucial to explore this foundation. Keeping in mind the controversy and progress of the philosophy of social sciences, this paper aims to elaborate on four aspects including the cognitive model, the view of causality, research methods, and analysis techniques, and to establish a more solid methodological basis for historical political science. With respect to the “upstream knowledge” of methodology, both positivism and critical realism underestimate the tremendous difference between the natural world and the social world. This leads to inherent flaws in controlled comparison and causal mechanism analysis. Given the constructiveness of social categories and the complexity of historical circumstances, the cognitive model of constructivism makes it more suitable for researchers to engage in macro-political and social analysis. From the perspective of constructivism, the causality in “storytelling,” i.e., the traditional narrative analysis, is placed as the basis of the regularity theory of causality in this paper, thus forming the historical–causal narrative. The historical–causal narrative focuses on how a research object is shaped and self-shaped in the ontological historical process, and thus ideally suits the disciplinary characteristics of historical political science. Researchers can complete theoretical dialogues, test hypotheses, and further explore the law of causality in logic and evidence, thereby achieving the purpose of “learning from history” in historical political science.

How Might World Heritage Status Support the Protection of Sacred Natural Sites? An Analysis of Nomination Files, Management, and Governance Contexts

This study provides an overview of how sacred natural sites are given recognition within the World Heritage system. It offers an analysis of the extent to which sacred natural sites that are part of nine World Heritage sites are recognised in site nomination files, management plans, and governance of these sites. The World Heritage sites are located across all continents except for Antarctica. We analysed sites in Australia, Greece, Guatemala, India, Japan, Kenya, Malaysia, New Zealand and the Russian Federation. We found that the cultural and spiritual significance of sacred natural sites is under-recognised, especially in natural World Heritage sites. In addition, Indigenous and religious custodians are frequently excluded from site management and governance. We make four recommendations for improving the recognition of sacred natural sites and the involvement of their custodians in the World Heritage process and in site nomination, governance, and management: (1) identification and recognition of sacred natural sites including their associated cultural and spiritual values; (2) recognition of, and articulated roles for custodians of sacred natural sites in the governance and management of World Heritage sites; (3) increased uptake of religious groups and Indigenous Peoples’ conservation approaches to the joint management of World Heritage sites that contain sacred natural sites, and (4) prevention of exclusion of custodians and ecological migration by applying inclusive conservation practices through rights-based approaches.

Compositional Closure—Its Origin Lies Not in Mathematics but Rather in Nature Itself

Compositional closure, spurious negative correlations in data sets of a fixed sum (e.g., fractions and percent), is often encountered in geostatistical analyses, particularly in mineralogy, petrology, and geochemistry. Techniques to minimize the effects of closure (e.g., log-ratio transformations) can provide consistent geostatistical results. However, such approaches do not remove these effects because closure does not result from mathematical operations but is an inherent property of the physical systems under study. The natural world causes physical closure; mathematics simply describes that closure and cannot alter it by manipulations. Here, we examine the distinct types of geologic systems and samples to determine in which situations closure (physical and mathematical) does or does not ensue and the reasons therefor. We parse compositional systems based on (1) types of components under study, immutable (e.g., elements) or reactive (minerals), and (2) whether the system is open or closed to component transfer. Further, open systems can be (1) displacive in which addition of a component physically crowds out others, or (2) accommodative in which addition or subtraction of components does not affect the others. Only displacive systems are subject to compositional closure. Accommodative systems, even with components expressed as percent or fractions, are not closed physically or, therefore, mathematically.

The Cambridge History of Philosophy of the Scientific Revolution

The early modern era produced the Scientific Revolution, which originated our present understanding of the natural world. Concurrently, philosophers established the conceptual foundations of modernity. This rich and comprehensive volume surveys and illuminates the numerous and complicated interconnections between philosophical and scientific thought as both were radically transformed from the late sixteenth to the mid-eighteenth century. The chapters explore reciprocal influences between philosophy and physics, astronomy, mathematics, medicine, and other disciplines, and show how thinkers responded to an immense range of intellectual, material, and institutional influences. The volume offers a unique perspicuity, viewing the entire landscape of early modern philosophy and science, and also marks an epoch in contemporary scholarship, surveying recent contributions and suggesting future investigations for the next generation of scholars and students.

Science, Poetics, and Immersive Field Ecology

Complex global challenges and declining scientific literacy demand novel approaches to engaging students with science and the natural world. While evidence supports integrating creative and scientific modes of inquiry, these approaches are often separated in undergraduate education. We designed Ecology Through the Writer’s Lens (ETWL) to allow students to explore an ecosystem of critical importance, the tall grass prairie, through an interdisciplinary field experience. Co-taught by Biology and English professors and open to students of all majors, ETWL leverages classroom activities to prepare for and process the immersive field experience over the course of one semester. Field-based exercises include natural history observations, hypothesis building, experimental design, analysis of the literature, and creative/reflective writing. Learning was assessed through multiple assignments, including a final creative project that spanned diverse writing genres. Students met and exceeded expectations with respect to course objectives. Non-science majors learned how scientific knowledge is generated; science majors learned how creative approaches can open new pathways for exploration. Many students overcame fear of natural spaces. Several students independently engaged with tall grass prairie in post-course activities. We conclude that interdisciplinary approaches to field-based inquiry can generate transformative experiences, even when the immersive component is short-term and close to home. ETWL provides one model by which different modes of inquiry can be blended to enhance student appreciation of science, literature, and the environment.

Threat to Nature Connectedness: How Does It Influence Consumers’ Preferences for Automated Products?

Connection with the natural world is a fundamental human need related to sustainable development. However, such a human need is very likely to be threatened in modern, industrialized society. This paper represents the first attempt to investigate the effect of perceived disconnection from nature on consumers’ preference for automated products (e.g., virtual assistants). Based on two surveys (276 adult participants) and one experimental study (282 adult participants), we found that perceived disconnection from nature can magnify consumers’ resistance to automated products. We further examined the underlying mechanism through moderated mediation model and revealed that consumers who perceive greater nature disconnection are less likely to perceive automated products as helpful friends, leading to a lower likelihood of adopting these products. The present research unveils this novel effect of perceived disconnection with nature on consumer behavior and provides fresh insight into how consumers’ preferences for automated products can be influenced by psychology rather than technology. Additionally, these findings can extend the research regarding sustainable consumption.
