The Proust Effect and Hoarding Symptoms: Relationships among Memory Vividness, Object Type, and Urge to Save
No full textBackground: Individuals with hoarding disorder exhibit heightened attachment to objects, but little is known about possible drivers of object attachment and associated object saving behaviors. Theory and preliminary evidence posit that the heightened object attachment characteristic of hoarding disorder may be partially explained by the experience of vivid,‘Proustian’ memories related to objects.
Aims: The current study piloted a novel Proustian Memory Task to examine whether self-reported vividness of memories associated with cherished objects, mundane objects, and non-objects was associated with greater urge to save objects and greater hoarding symptoms.
Method: Participants (N= 443) included a non-selected community sample recruited from the crowd-sourcing platform Prolific. Participants were asked to identify and describe a memory associated with their most cherished belonging, a mundane belonging, and a recent vacation (i.e. non-object control). Participants also reported their urge to save the identified objects and completed a self-report measure of hoarding symptoms.
Results: Hoarding symptoms were not associated with vividness of memories of cherished objects, or with non-objects, but were associated with greater vividness of memories of mundane objects. Greater vividness of memories associated with objects was associated with a greater urge to save both cherished and mundane objects; however, this relationship was stronger for mundane compared with cherished objects. The relationship between memory vividness and urge to save objects was not impacted by hoarding symptoms.
Conclusions: Findings provide preliminary evidence that the experience of Proustian memories, particularly those related to mundane objects, may play a role in object attachment and hoarding symptoms
Examining the Intersectional and Structural Issues of Routine Healthcare Utilization and Access Inequities for LGB People with Chronic Diseases
No full textIn the United States, although the gaps in health insurance coverage by sexual orientation have been closing since the implementation of the Affordable Care Act and legalization of same-sex marriage, the LGB group (i.e., lesbian, gay, bisexual) continues to report healthcare utilization and access inequities such as more delayed or unmet care. The extant research has often examined healthcare utilization and access inequities due to affordability (e.g., out-of-pocket costs). However, healthcare utilization and access inequities are only partially explained by cost reasons; there are non-cost reasons that have not been adequately empirically examined. The present study innovatively includes discrimination structural variables to understand how social structure is associated with healthcare utilization and access inequities of LGB people. It focuses on two routine health services—regular check-ups and prescription medications—for LGB people who have chronic diseases. Additionally, sexual orientation may intersect with sex assigned at birth (sex, hereafter, i.e., male, female) to impact healthcare utilization and access inequities. The current study applies quantitative intersectional analysis to understand healthcare utilization and access inequities from a sexual orientation and sex intersectional lens and for easier and clearer interpretations of intersectional results and more actionable policy implications for inter-categorical groups. Using the 2023 National Health Interview Survey (weighted N = 136,231,053), we con- ducted quantitative intersectional analysis for logistic regression using complex survey data. First, we fit a series of logistic regression models with sexual orientation–sex inter- actions for routine healthcare utilization and access outcomes, adjusting for covariates. Second, we calculated average marginal predictions for inter-categorical groups by inter- acting sexual orientation and sex and other covariates. Third, we computed risk ratios of average marginal predictions for all the covariates. Lastly, we examined the interaction of inter-categorical groups/sexual orientation and structural variables. Our results show that experiencing a higher level of discrimination is positively associated with underutilization of regular check-ups and lower access to prescription medications, and this effect is stronger for LGB people. Further, LGB women are least likely to utilize regular check-ups and LGB men are least likely to access prescription medications among the inter-categorical groups. Highlighting structural issues of healthcare utilization and access offers new evidence on healthcare utilization and access inequities that can inform policies for raising awareness of and addressing structural issues. The intersectional analyses suggest that relevant policies target LGB women and LGB men

Full text linkThis volume contains the proceedings of the AMS Special Session on Higher Structures in Topology, Geometry, and Physics, held virtually on March 26–27, 2022.
The articles give a snapshot survey of the current topics surrounding the mathematical formulation of field theories. There is an intricate interplay between geometry, topology, and algebra which captures these theories. The hallmark are higher structures, which one can consider as the secondary algebraic or geometric background on which the theories are formulated. The higher structures considered in the volume are generalizations of operads, models for conformal field theories, string topology, open/closed field theories, BF/BV formalism, actions on Hochschild complexes and related complexes, and their geometric and topological aspects.https://scholarworks.smith.edu/mth_books/1001/thumbnail.jp
The Rise and Fall of King Coal: American Energy Transitions in an Age of Markets, 1800–1940
No full textA history of the dynamic role of coal in the energy landscape of the United States during the nineteenth and twentieth centuries.
In The Rise and Fall of King Coal, Mark Aldrich explores the pivotal role of coal in the historical energy landscape of the United States. Meticulously researched and clearly written, this analysis of the rise, dominance, and eventual decline of coal as a primary fuel source traces its evolution from the late eighteenth century to the mid-twentieth century.
Aldrich explains the factors that contributed to coal\u27s ascendancy and decline, including efficiency, marketing, and the technological advancements that facilitated both its widespread adoption and later languishing. A complex interplay among market forces, government policies, and societal attitudes profoundly shaped the coal industry\u27s trajectory. Challenges and controversies have surrounded the production of coal since its inception, including labor issues, environmental concerns, and resource scarcity. Aldrich\u27s comprehensive approach—which combines historical analysis, economic perspectives, and a deep appreciation for the technological and scientific advancements that transformed the energy landscape—also emphasizes the role of innovation and entrepreneurship in driving energy transitions.
By providing a bottom-up history that underscores the pivotal role of individual choices and market dynamics, The Rise and Fall of King Coal offers valuable insights into the dynamic nature of energy transitions. In lively discussions of domestic cooking and heating, Aldrich emphasizes the importance of women in shaping households\u27 energy choices, and he gives voice to individual women and men as they describe how these decisions raised their standard of living. This book represents a seminal contribution to the field of energy history and highlights the complex interplay of factors that have shaped the evolution of energy use in the United States.

The Gift of Giving: Recognizing Donors and Revealing Donation Amounts
Full text linkPublicly announcing how much individuals donate on behalf of themselves is a common fundraising strategy. For tribute gifts made on behalf of others, however, charities only reveal donor identities to the honoree with few revealing the size of their contributions. This paper examines the fundraising consequences of recognizing donors with and without information about donation amounts when notifying honorees of gifts made on their behalf. I find that revealing contribution amounts in addition to recognizing donors benefits fundraisers. I find that both the likelihood of giving on behalf of others and contribution amounts increase when honorees learn how much donors give. The results either suggest that fundraisers are leaving tribute donations on the table, or that announcing the size of these gifts may be repugnant and constrains what practices fundraisers can implement
Single-Cell Genomics Reveals Complex Microbial and Viral Associations in Ciliates and Testate Amoebae
No full textProtists play important roles in nutrient cycling across ecosystems, yet the composition and function of their associated microbiomes remain poorly studied. Here, we use cultivation-independent single-cell isolation and genome-resolved metagenomics to investigate the microbiomes and viromes of more than 100 uncultivated ciliates and amoebae from diverse environments. Our findings reveal unique microbiome structures and complex associations with bacterial symbionts and viruses, with stark differences between ciliates and amoebae. We recover 117 microbial genomes affiliated with known eukaryotic endosymbionts, including Holosporales, Rickettsiales, Legionellales, Chlamydiae, and Babelota, and 258 genomes linked to host-associated Patescibacteriota. Many show genome reduction and genes related to toxin-antitoxin systems and nucleotide parasitism, indicating adaptation to intracellular lifestyles. We also identify more than 80 giant viruses from diverse lineages, some actively expressing genes in single-cell transcriptomes, along with other viruses predicted to infect eukaryotes or symbiotic bacteria. The frequent co-occurrence of giant viruses and microbial symbionts, especially in amoebae, suggests multipartite interactions. Together, our study highlights protists as hubs of microbial and viral associations and provides a broad view of the diversity, activity, and ecological importance of their hidden partners
