Although the individual has been the focus of most research into judgment and decision-making (JDM), important decisions in the real world are often made collectively rather than individually, a tendency that has increased in recent times with the opportunities for easy information exchange through the Internet. From this perspective, JDM research that factors in this social context has increased generalizability and mundane realism relative to that which ignores it. We delineate a problem-space for research within which we locate protocols that are used to study or support collective JDM, identify a common research question posed by all of these protocols—‘What are the factors leading to opinion change for the better (‘virtuous opinion change’) in individual JDM agents?’—and propose a modeling approach and research paradigm using structured groups (i.e., groups with some constraints on their interaction), for answering this question. This paradigm, based on that used in studies of judge-adviser systems, avoids the need for real interacting groups and their attendant logistical problems, lack of power, and poor experimental control. We report an experiment using our paradigm on the effects of group size and opinion diversity on judgmental forecasting performance to illustrate our approach. The study found a U-shaped effect of group size on the probability of opinion change, but no effect on the amount of virtuous opinion change. Implications of our approach for development of more externally valid empirical studies and theories of JDM, and for the design of structured-group techniques to support collective JDM, are discussed.

This study investigated links between the development of children’s understanding of ironic comments and their metapragmatic knowledge. Forty-six 8-year-olds completed the short version of the Irony Comprehension Task, during which they were presented with ironic comments in three stories and asked to provide reasons for why the speaker in a story uttered an ironic comment. We coded their responses and compared the results to similar data collected previously with 5-year-olds. Results showed that compared to younger children, 8-year-olds frequently refer to interlocutors’ emotions, intentions, and to metapragmatics. These results support the view that comprehension of verbal irony is an emerging skill in children.

The Swan Point site in interior Alaska contains a significant multi-component archaeological record dating back to 14,200 cal BP. The site’s radiocarbon (14C) chronology has been presented in scattered publications that mostly focus on specific archaeological periods in Alaska, in particular its terminal Pleistocene components associated with the East Beringian tradition. This paper synthesizes the site’s 14C data and provides sequential Bayesian models for its cultural zones and subzones. The 14C and archaeological record at Swan Point attests that the location was persistently used over the last 14,000 years, even though major changes are evident within regional vegetation and local faunal communities, reflecting long-term trends culminating in Dene-Athabascan history.

OBJECTIVES/GOALS: To examine i) how longstanding (≥6 years) community-based participatory research (CBPR) partnerships nationwide implemented a validated questionnaire to measure success and its contributing factors and ii) how the CBPR partnerships utilized and applied a feedback mechanism, or reports of findings from the questionnaire and a facilitation guide METHODS/STUDY POPULATION: This mixed methods study builds upon a larger NIH-funded project entitled ’Measurement Approaches to Partnership Success (MAPS). MAPS developed and validated the 109-item MAPS questionnaire to measure success in longstanding (≥6 years) CBPR partnerships. In 2020, 55 CBPR partnerships nationwide completed the MAPS Questionnaire and, a year later, received the MAPS Feedback Mechanism, consisting of questionnaire findings and a facilitation guide on how to present the findings. In this follow-up study, we administered multi-method surveys to each partnership contact person in 2022 to examine their experience with and utility of the MAPS Questionnaire and the MAPS Feedback mechanism. We performed descriptive analysis of quantitative responses using SAS and thematic analysis of qualitative responses. RESULTS/ANTICIPATED RESULTS: Survey responses have been presently collected from 14 partnerships. Preliminary findings suggest that the most frequently reported benefits of completing the MAPS Questionnaire included stimulating partnership reflections and ease of completion. Many partnerships shared results of the MAPS Questionnaire by e-mail or during partnership meetings. Nearly half of the partnerships rated components of the MAPS feedback mechanism as useful. Over one-third of the partnerships reported that the COVID pandemic limited their capacity to engage with the MAPS Feedback Mechanism. Key qualitative suggestions included making the MAPS Questionnaire shorter, providing it in a different format, and offering additional facilitation to support the implementation of the MAPS Feedback Mechanism. DISCUSSION/SIGNIFICANCE: This study examines how CBPR partnerships utilize an evaluation instrument and apply results on success. Current findings suggest potential utility of the MAPS Questionnaire and Feedback Mechanism for ongoing evaluation. Reducing the questionnaire length and providing facilitation resources may enhance implementation across diverse settings.

This article explores the exiling of Napoleon Bonaparte, Emperor of the French, in 1814 and 1815. It argues that in confronting Napoleon’s sovereignty and trying to remove him, the allies were forced to make a highly pragmatic, improvisational, and incoherent use of international law. Much of this stemmed from that fact that they were trying to implement a Great Powers political system within and through a legal system that was antithetical to any such concept. Because of this the allies move between employing traditional, domestic understandings of sovereignty, to treating sovereignty as something capable of international control and distribution. This results in an incoherent legal argument and narrative, with each turn of the tale adding layer upon layer of further confusion and contradiction. The conclusion of all this is Napoleon’s miserable dispatch to St. Helena by the British government – speedily done and in fear of a legal challenge.

To define suitable holding conditions for fish used in experimental studies on food consumption and growth, the effect of cover on growth at two ration levels was quantified for immature individuals of two common, freshwater species: the threespine stickleback (Gasterosteus aculeatus: Gasterosteidae) and the European minnow (Phoxinus phoxinus: Cyprinidae). In the European minnow, the presence of cover significantly increased growth rates and also the rate of food consumption at ad libitum rations; however, cover had no significant effect on the growth of the threespine stickleback. In both species, fish fed ad libitum rations had higher growth rates than fish fed 4% of body weight per day. This study illustrates the need for species specific holding conditions and illustrates an approach to welfare using measurements of traits closely related to fitness.

This article explores the UK vote in 2016 to exit the European Union, colloquially known as ‘Brexit’. Brexit has been portrayed as a British backlash against globalisation and a desire for a reassertion of sovereignty by the UK as a nation-state. In this context, a vote to leave the European Union has been regarded by its protagonists as a vote to ‘take back control’ to ‘make our own laws’ and ‘let in [only] who we want’. We take a particular interest in the stance of key ‘Brexiteers’ in the UK towards regulation, with the example of the labour market. The article commences by assessing the notion of Brexit as a means to secure further market liberalisation. This analysis is then followed by an account of migration as a key issue, the withdrawal process and likely future trajectory of Brexit. We argue that in contrast to the expectations of those who voted Leave in 2016, the UK as a mid-sized open economy will be a rule-taker and will either remain in the European regulatory orbit, or otherwise drift into the American one.

There are very few records of past terrestrial environmental change of any time period for the Australian tropical savannas. Here we document the hydrological development of Sanamere Lagoon, north Queensland, from a 1.72 m sediment sequence with a basal age of ca. 33 ka. We measure a variety of proxies reflecting environmental change within and around the lagoon, including grain size, elemental and diatom abundance, and carbon and nitrogen isotope composition. By integrating the interpretation of multiple proxies, we show that regional climatic events, such as the reactivation of the monsoon at 15 ka and sea-level rise ending at 7 ka, are reflected in local ecosystem change and a diversity of biogeochemical responses in Sanamere Lagoon. This record makes a significant contribution to the development of records of environmental change from an under-studied region in tropical Australia through the Holocene to the LGM and beyond—a step towards enabling a more detailed understanding of regional monsoon (paleo)dynamics. In particular, this study highlights nuances in the effect of Indonesian-Australian Summer monsoon dynamics in a region less affected by sea level and continental shelf drowning complexities.

The new mineral bounahasite, Cu+Cu2+2(OH)3Cl2, was found in the oxidation zone of the Bou Nahas Mine, Morocco. It forms pseudo-hexagonal plates up to 3 × 30 × 40 μm in size combined in loose clusters with native copper and paratacamite. The mineral is green with vitreous lustre. The cleavage is parallel to {110}, perfect. Dcalc is 3.90 g/cm3. The infrared spectrum is reported. The composition (wt.%) is Cu2O 23.26, CuO 51.72, Cl 23.36, H2O 8.71, O = Cl2 –5.27, total 101.78. The empirical formula calculated on the basis of 3 Cu atoms per formula unit is: Cu+Cu2+2(OH)2.97Cl2.03. The mineral is monoclinic, P21/n, a = 8.5925(1), b = 6.4189(1), c = 10.4118(2) Å, β = 111.804(2)°, V = 533.17(2) Å3 and Z = 4. The strongest reflections of the powder X-ray diffraction pattern [d,Å(I)(hkl)] are: 7.71(70)($\bar{1}$01), 5.34(22)(011), 3.856(100)(012, $\bar{2}$02), 2.673(36)(022), 2.665 (30)(103) and 2.350 (71)($\bar{1}$23, 301, $\bar{2}$14). The crystal structure, refined from single-crystal X-ray diffraction data (R1 = 0.028), is based on two alternating sheets coplanar to (110): one consists of alternating edge-sharing Cu2+(OH)6 octahedra and two Cu2+(OH)4Cl2 octahedra, whereas the other one is based on Cu+Cl4 tetrahedra forming edge-sharing Cu+2Cl6 dimers.
