We report new interpretation of >19,500 beach strandlines from waterbodies in the western St. Lawrence and Champlain Lowlands in northern New York and adjacent areas of Vermont, Quebec, and Ontario from ≤2-m-resolution digital elevation models. Strandline evidence supports a deglaciation model in which proglacial lake and marine shoreline deposits adjusted continuously in response to steady shoreline regression linked to outlet incision, differential isostatic adjustments, and postglacial relative sea-level rise. Gaps in strandline preservation reflect times of rapid water-level decline associated with breakout floods and abrupt shifts in drainage to new outlets. Water levels returned to slower, steady decline and renewed beach sedimentation during the later stages of a breakout as water levels in the source and receiving waterbodies equilibrated. Our conclusions contrast with previous models that infer discrete lake stages were controlled by stable outlets then fell abruptly as lower outlets were exhumed from beneath the Laurentide Ice Sheet during deglaciation. We present a new deglacial chronology and lake nomenclature that reflects this paradigm and redefines the spatial and temporal distributions of proglacial lake and marine water in the region.

Italian ryegrass is a troublesome weed species commonly found across the United States. In North Carolina, biotypes resistant to herbicides from Groups 1, 2, and 9 have been confirmed. In fall 2020, multiple growers reported unsatisfactory control of Italian ryegrass after sequential burndown applications of paraquat in the Southern Piedmont region of the state. The objectives of this study were to confirm the presence of a paraquat-resistant Italian ryegrass biotype in the state through a whole-plant dose–response bioassay and to characterize the response of Italian ryegrass accessions from the same region to commonly used burndown herbicides. Greenhouse studies were conducted at the North Carolina State University weed science laboratories to evaluate the response of three putative paraquat-resistant Italian ryegrass biotypes (B, H, SB) and four putative susceptible biotypes (S1, S2, S3, and S4) to paraquat rates ranging from 52.5 to 26,880 g ai ha−1 and the response of 38 accessions to clethodim (271 g ai ha−1), glyphosate (1,260 g ae ha−1), glufosinate (880 g ai ha−1), nicosulfuron (34 g ai ha−1), and paraquat (840 g ai ha−1). The effective paraquat dose required to reduce biomass by 50% (GR50) for the putative paraquat-resistant biotypes ranged from 570 to 1,729 g ai ha−1, equivalent to 19- to 58-fold more resistant to paraquat compared to the average GR50 of susceptible biotypes. This study confirms the presence of paraquat-resistant Italian ryegrass in North Carolina. Results from the accessions study reveal that 29% of biotypes tested were resistant to paraquat, all of which also exhibited resistance to glyphosate and nicosulfuron. Additionally, a wide distribution of multiple herbicide–resistant biotypes was observed in the Southern Piedmont region, with 97% and 74% of accessions tested resistant to ≥1 and ≥2 sites of action, respectively.

The Guanajuato Mining District of central Mexico is one of the main silver and gold deposits in the world. It is in the State of Guanajuato in the southern part of the Sierra Madre Occidental (SMO) volcanic province. The mining district developed within a mid-Tertiary volcano-sedimentary sequence that includes thick alluvial-fan deposits accumulated in a tectonic basin during the Eocene-Oligocene named the Guanajuato Red Conglomerate and an overlying volcanic sequence mostly pyroclastic of Oligocene age. The mid-Tertiary stratigraphy of Guanajuato is revised and reinterpreted in the light of new fieldwork and U-Pb ages, which document a close timing between all units of the volcanic succession at the top of the Guanajuato Red Conglomerate. This sequence is made of pyroclastic density current deposits formed during episodic events from the Guanajuato caldera. A new nomenclature of the caldera’s units is proposed; the Guanajuato Caldera Volcanic Group, which includes the Guanajuato Pyroclastic Formation represented by the Loseros PDC deposits and the Bufa-Calderones ignimbrites emplaced around 32.8 ± 0.2 Ma, and the post-collapse lava domes of El Rodeo and Chichíndaro formations emplaced at 31–30 Ma. Apparently, a resurgent pulse of the caldera uplifted the collapsed intra-caldera blocks, so that the caldera floor is now exposed. The caldera collapse was controlled by the pre-existing normal faults inherited from the previous tectonic basin; thus, it is classified as a graben-type caldera, with a square shape and a size of 15 × 16 km. By comparison with other similar calderas of Mexico, the Guanajuato caldera is another case study of graben-type calderas of the SMO coinciding with mineral districts, such as Bolaños (Jalisco).

Integrating nature and green space into urban areas is a growing social challenge. The dollar value that renters place on public amenities when choosing where to live is essential for policymakers and urban planners looking to provide equitable access to environmental amenities and other public goods. This study estimates renter willingness to pay (WTP) for urban green space in the greater Boston area, utilizing a sorting model framework with data on census, transit, and neighborhood quality measures. My results suggest that renter household WTP is between $1.17 and $1.64 for an additional percentage point of urban green space in their location decisions. I examine differences in WTP for green space between white and minority renters, uncovering both shared and divergent sorting behaviors, as well as disparities in the distribution of environmental benefits across groups.

Rituals are sites of personal and social transformations. However, we still do not have a sophisticated theory for how these rituals were embedded and generated within specific political economies, nor how communities used ritual activities to conceptualize the cosmos. This paper develops a theoretical framework exploring pragmatism and materialism to articulate the relationship between imperial political economies and ritual activities, situating the latter in the former. This framework will then be applied to ritual activities in southern Roman Britain, exploring how ritual activities emerged within the imperial political economy. The emergence of Roman imperialism in Roman Britain materially impacted upon not only the nature and range of ritual activities, but also the cosmologies of local communities. Ritual activities are materializations of cosmological beliefs, and both were determined by the imperial political economy. It is this process by which cosmologies emerged to naturalize socially constructed relations and activities that I call ontogenesis.

This study investigated the effects of audience design and goal bias in Chinese speakers’ message generation of source-goal motion events (e.g., A bird flies from the tree to the house), using picture description and memory tasks. The status of the source (e.g., the tree) or the goal (e.g., the house) was manipulated as known or unknown to the confederate addressees. The findings revealed that the participants were more likely to omit the sources when they were mutually known to the addressee than when they were not. However, participants showed similar accuracy in detecting source changes, regardless of whether the sources were known to the addressee. Moreover, they consistently mentioned goals and showed similar accuracy in detecting goal changes, regardless of whether the goals were known or unknown to the addressee. The results suggest that audience design influenced the speakers’ mention of sources, but not their memory of them. It did not affect either the mention or the memory of goals. Goal bias was not consistently observed across the two experiments, both linguistically and in memory. This suggests a fragile goal bias in Chinese. Taken together, these findings demonstrate that audience design and goal bias influence the message generation of motion events in Chinese speakers.

Public health campaigns among Catholic Mexican American populations in New Mexico in the mid-twentieth century often relied on the expertise of anthropologists and sociologists to help tailor the campaigns to Mexican American culture. Social scientists produced several reports based on fieldwork that suggested that New Mexican village religious practices and beliefs, often referred to as “folk Catholicism,” were durable barriers to embracing scientific healthcare standards. This article uses those reports to reveal and analyze the role that public health campaigns and social science researchers played in defining and challenging Hispano religious healing traditions. It likewise examines the various intersections of science and racializing discourse in the reports. I argue that these social scientific studies of Spanish-speaking, New Mexican village culture were intended to facilitate the “right” kind of assimilation to Anglo cultural norms around health, one that paradoxically aimed to include Hispanos in modern medicine while simultaneously defining essential religio-racial difference. The regulation of Hispano bodies rested on social scientific discourses that racialized religion, science, and health.

This article responds to Wells & Giacco’s discussion of the theoretical frameworks that guide qualitative research. In addition to the methods they explore, I describe ethnography, focusing on the anthropological investigation of culture. I use examples from the research literature to highlight the unique values of ethnography. I describe what ethnography entails, before outlining illustrations of how ethnographic research has contributed to psychiatric clinical practice. Although it is difficult to generalise from the findings of ethnographic research, its focus on how social processes work and how people perceive them in a particular context makes it useful for advancing improvements in clinical care.

While a growing body of literature studies the effects of weather shocks on economic activity in low-income countries, relatively little is known about their impact on cross-border capital flows. This study investigates whether weather shocks, specifically deviations in precipitation and temperature from their long-term averages, trigger capital flight from Africa. Exploiting the variation in within-country exposure to weather shocks, we find that temperature shocks lead to increased capital outflows and trade misinvoicing. The long-run relationship between temperature and capital flight is conditional upon country-specific factors, such as reliance on oil exports, institutional frameworks and financial infrastructures. Our findings reveal a moderate role of state capacity in the relationship between weather shocks and capital flight, highlighting the need for further investigation into other potential mechanisms.

The aim of this study is to explore how large language models (LLMs) integrated with structured versus unstructured concept generation techniques (CGTs) influence designers’ creative thinking processes and outputs. Using human–human collaboration (HHC) as a baseline, a 2 × 2 mixed factorial design was adopted to investigate the effects of collaborator type (between-subjects: LLM-based agents vs. experienced designers) and CGT type (within-subjects: brainstorming vs. TRIZ). Two LLM-based agents, IntelliStorm and EvoluTRIZ, were developed for the study, with 32 participants randomly assigned to either the HHC or human–agent collaboration (HAC) groups. Brain activity was measured using functional near-infrared spectroscopy, while outputs were assessed through expert evaluations. Results showed that designers exhibited lower cognitive load, better cognitive resource coordination, and enhanced fluency and flexibility in thinking in HAC than in HHC. Moreover, distinct patterns were revealed in different CGTs: brainstorming activated the right dorsolateral prefrontal cortex (PFC) as the core connectivity region, enhancing ideational fluency, whereas TRIZ activated the left dorsolateral PFC, facilitating refined thinking. Although HAC demonstrated stronger overall performance, HHC retained unique advantages in originality. This research offers novel neuroscientific insights and provides evidence-based guidance for developing more effective LLM-based design agents.
