Migration challenges how we think about justice and state sovereignty. This is no less the case for political theorists, and this review symposium focuses on the work of one of the foremost political theorists working on these questions today. In his latest book – Strangers in Our Midst: The Political Philosophy of Migration – David Miller argues for a realist approach to migration, an approach that takes into consideration not just what we ought to do, but also the actual possibilities of implementing justice. In this regard, the relationship between (im)migration and state sovereignty and democracy is central. Miller’s approach is a ‘political’ one that seeks to take into consideration the fact that we live in political communities with (more or less) shared values, and that these political communities cannot easily be disentangled from the liberal democratic institutions of these states. In their reviews of Miller’s book, Sarah Song, Annie Stilz and Kieran Oberman all take issues with particular aspects of Miller’s approach, while also accepting the general thrust to think about migration in the context of state and popular sovereignty.
Effective waterhemp management in crop rotations that include sugar beet requires a proactive approach, starting with robust weed management in the preceding crop. Sugar beet is vulnerable to weeds due to its poor competitiveness during its early growth stages and a limited availability of effective herbicide options within this rotation. This research aimed to evaluate multi-tactic weed management strategies, including planting soybean in narrow rows with low- and high-input treatments, and a high-input treatment plus harvest-time weed seed control (HWSC) simulation, on waterhemp control and seed production in soybean, and their effects on waterhemp density in the following sugar beet crop. Field experiments were conducted from 2021 to 2023 in Franklin, Moorhead, and Rosemount, Minnesota. Soybean planted in narrow rows closed the canopy earlier at Franklin in 2021 and at Moorhead in 2022. Soybean row spacing did not affect waterhemp control, density, biomass, or seed production at any site-year. A high-input treatment consisting of flumioxazin applied preemergence followed by (fb) an early postemergence application of lactofen + acetochlor fb a late-postemergence application of 2,4-D + glyphosate provided ≥95% waterhemp control at harvest at all site-years and seed production was reduced to 0 seeds m−2 at Franklin and Rosemount. At those locations, waterhemp control at harvest was comparable among all high-input herbicide treatments. Soybean planted in narrow rows yielded 9.4% and 18.5% more than soybean planted in wide rows at Franklin and Rosemount, respectively, while no yield difference was observed at Moorhead. Waterhemp emergence in the subsequent season’s sugar beet crop fell by 72% to 92% at the Franklin site in 2022, Moorhead in 2023, and Rosemount in 2023 after high-input herbicide treatments. However, adding HWSC to a high-input treatment did not result in a further reduction of waterhemp density. In this research, 1 yr of effective waterhemp control with high-input herbicide treatments in soybean reduced waterhemp emergence in the following season’s sugar beet crop.
We corroborate findings showing a disparity in one’s willingness to update political beliefs in the face of counterevidence among bilinguals, examining the role of the Foreign Language effect (FLe) on belief maintenance. 133 Liberal English-Spanish bilinguals and 70 English monolinguals showed that belief change on political issues is lesser than on nonpolitical issues following counterevidence. Bilinguals, however, showed greater change in the second language (L2) compared to the first and greater belief change than the monolinguals overall. The second language also led to slower reading and rating times across all conditions, which corresponded with greater belief change. Among bilinguals using their L2, those most likely to show belief change reported having a less meaningful connection to the foreign language.
Design teams commonly need to explain the rationale or logic behind how they frame design challenges and develop a particular design concept and not others. This paper explores the use of Design Logic Visualizations (DLV) as a boundary object to enhance understanding and communication in convergent interdisciplinary engineering design environments. We developed the DLV as a new design tool, building upon existing design process visualizations like design signatures, and provide a case study from our NASA team. We then use a reflection-based autoethnographic and collaborative inquiry approach to reflect on how the DLVs influenced our team, our process, and our decision-making. The findings suggest DLVs can serve as a succinct storytelling tool, support shared understanding across disciplines and levels of leadership, and, ultimately, influence design outcomes.
Genetic research on nicotine dependence has utilized multiple assessments that are in weak agreement.
Methods
We conducted a genome-wide association study (GWAS) of nicotine dependence defined using the Diagnostic and Statistical Manual of Mental Disorders (DSM-NicDep) in 61,861 individuals (47,884 of European ancestry [EUR], 10,231 of African ancestry, and 3,746 of East Asian ancestry) and compared the results to other nicotine-related phenotypes.
Results
We replicated the well-known association at the CHRNA5 locus (lead single-nucleotide polymorphism [SNP]: rs147144681, p = 1.27E−11 in EUR; lead SNP = rs2036527, p = 6.49e−13 in cross-ancestry analysis). DSM-NicDep showed strong positive genetic correlations with cannabis use disorder, opioid use disorder, problematic alcohol use, lung cancer, material deprivation, and several psychiatric disorders, and negative correlations with respiratory function and educational attainment. A polygenic score of DSM-NicDep predicted DSM-5 tobacco use disorder criterion count and all 11 individual diagnostic criteria in the independent National Epidemiologic Survey on Alcohol and Related Conditions-III sample. In genomic structural equation models, DSM-NicDep loaded more strongly on a previously identified factor of general addiction liability than a “problematic tobacco use” factor (a combination of cigarettes per day and nicotine dependence defined by the Fagerström Test for Nicotine Dependence). Finally, DSM-NicDep showed a strong genetic correlation with a GWAS of tobacco use disorder as defined in electronic health records (EHRs).
Conclusions
Our results suggest that combining the wide availability of diagnostic EHR data with nuanced criterion-level analyses of DSM tobacco use disorder may produce new insights into the genetics of this disorder.
To provide a useful contextual backdrop to an exhibition at the Royal College of Psychiatrists this summer, we used a question and answer format to summarise the thoughts of its curator, Gavin Miller. Gavin has chosen 12 books published by Penguin between 1949 and 1975 to illuminate the relationship between psychiatrists, psychologists, psychotherapists and the British media. He reflects on the opportunities and pitfalls that come with the association, the motivations of previous writers and provides practical advice for any media psychiatrists considering such a role in the future. The exhibition is open to visitors to the College building in London.
Objectives/Goals: The Wake Forest Clinical and Translational Science Institute (CTSI) has integrated academic goals of T0-T4 translation, scholarship, and education into our Academic Learning Health System (aLHS) framework. Our Translation Research Academy (TRA) provides rigorous training for outstanding and diverse K12 and early-career faculty to develop LHS core competencies. Methods/Study Population: The TRA Forum is the main vehicle for delivering an aLHS-oriented curriculum. Currently, the program includes six K12 scholars and 18 other early-career research faculty with facilitated access to CTSI resources. The TRA Forum is a 2-year seminar series that meets twice a month to discuss topics relevant to the aLHS, leadership, and career development. Inclusion of first- and second-year scholars facilitates peer mentorship, allowing Year 2 scholars to share insights with new scholars. Forum sessions are developed around adult learning theory: Each participant is asked to contribute their experience to discussions, and sessions focus on real-world examples. Results/Anticipated Results: Scholar and faculty commitment is very high. For the first 30 min., scholars present their work in small groups. This extends the range of disciplines exposed (64% of TRA graduates found this very helpful) and promotes translational traits of boundary crosser, team player, and systems thinker. Participants view the TRA as an opportunity to form internal peer networks, promote peer mentoring, and establish new collaborations. The remaining 60 minutes are used for education. Sessions include nominated topics and those providing a solid foundation in core aLHS competencies and characteristics of translational scientists. Educational sessions (97%) were rated as helpful or very helpful. Discussion/Significance of Impact: TRA scholars receive rigorous training in a highly supportive environment to produce aLHS researchers with skills to transcend boundaries, innovate systems, create new knowledge, and rigorously evaluate results.
Vascular rings represent a heterogeneous set of aberrant great vessel anatomic configurations which can cause respiratory symptoms or dysphagia due to tracheal or oesophageal compression. These symptoms can be subtle and may present at varied ages. More recently, many have been identified in patients without symptoms, including fetal echocardiogram, resulting in a conundrum for practitioners when attempting to determine who will benefit from surgical correction. Here, we provide a review of vascular rings and a guide to the practitioner on when to consider additional imaging or referral. Additionally, we discuss the changing landscape regarding asymptomatic patients and fetal echocardiogram.
Palmer amaranth, a competitive weed in cotton and soybeans, poses challenges due to its rapid growth, high fertility, and herbicide resistance. Effective management strategies targeting sex ratios could reduce seed production by female plants. Protoporphyrinogen oxidase (PPO-) inhibiting herbicides play a role in the evolving resistance of Amaranthus spp. in the US Midwest. These herbicides may also affect the male-to-female ratio of Palmer amaranth. A 2-yr field experiment (2015 and 2016) was conducted in a soybean field in Collinsville, IL, evaluating various preemergence and postemergence PPO-inhibiting herbicide treatments. Untreated Palmer amaranth populations exhibited a bias toward females. Preemergence application of sulfentrazone and flumioxazin effectively reduced Palmer amaranth density (1.66 plants m–2) throughout the season, whereas postemergence applications of fomesafen and lactofen provided limited control (27 and 31 plants m–2, respectively). Early-season mortality was high (96%) among Palmer amaranth seedlings, especially with pyroxasulfone + fluthiacet-methyl treatment. Fomesafen increased female biomass (28.8%) while reducing male biomass compared to the nontreated control. In 2015, pyroxasulfone + fluthiacet-methyl and acetochlor altered the male-to-female sex ratio compared to the nontreated control, with pyroxasulfone + fluthiacet-methyl reducing the proportion of females (–0.11 M/F) and acetochlor slightly increasing the proportion of males (0.03 M/F), though not different from a 1:1 ratio. In 2016, pendimethalin and flumioxazin (71 g ai ha–1) resulted in a strong female-biased sex ratio, with an almost exclusively female population. In both years, the nontreated control plots (–0.58 and –0.55 M/F) maintained a naturally female-biased sex ratio, deviating significantly from a 1:1 ratio. These findings suggest that specific herbicide treatments can alter the sex ratio. Understanding sex determination in Palmer amaranth holds promise for developing more effective control strategies in the future.
The articles compiled here offer examples of how the impacts of anthropogenic climate change in coastal settings are monitored and measured, how the broader public can be involved in these efforts, and how planning for mitigation can come about. The case studies are drawn from the southeastern United States and the British Isles, and they indicate the great potential that cooperating communities of practice can offer for addressing climate-change impacts on cultural heritage.
Given the US population concentration near coastal areas and increased flooding due to climate change, public health professionals must recognize the psychological burden resulting from exposure to natural hazards.
Methods
We performed a systematic search of databases to identify articles with a clearly defined comparison group consisting of either pre-exposure measurements in a disaster-exposed population or disaster-unexposed controls, and assessment of mental health, including but not limited to, depression, post-traumatic stress (PTS), and anxiety.
Results
Twenty-five studies, with a combined total of n =616 657 people were included in a systematic review, and 11 studies with a total of 2012 people were included in a meta-analysis of 3 mental health outcomes. Meta-analytic findings included a positive association between disaster exposure and PTS (n = 5, g = 0.44, 95% CI 0.04, 0.85), as well as depression (n = 9, g = 0.28, 95% CI 0.04, 0.53), and no meaningful effect size in studies assessing anxiety (n = 6, g = 0.05 95% CI −0.30, 0.19).
Conclusions
Hurricanes and flooding were consistently associated with increased depression and PTS in studies with comparison groups representing individuals unaffected by hazards.
Meta-analysis is the quantitative analysis of results of a research literature. Typically, meta-analysis is paired with a systematic review that fully documents the search process, inclusion and exclusion criteria, and study characteristics. A key feature of meta-analysis is the calculation of effect sizes – metric-free indices of study outcome that allow the mathematical combination of effects across studies. The methodological literature on meta-analysis has grown rapidly in recent years, yielding an abundance of resources and sophisticated analytic techniques. These developments are improvements to the field but can also be overwhelming to new aspiring meta-analysts. This chapter therefore aims to demystify some of that complexity, offering conceptual explanations instead of mathematical formulas. We aim to help readers who have not conducted a meta-analysis before to get started, as well as to help those who simply want to be intelligent consumers of published meta-analyses.
Experiments have gained prominence in sociology in recent years. Increased interest in testing causal theories through experimental designs has ignited a debate about which experimental designs can facilitate scientific progress in sociology. This book discusses the implications of research interests for the design of experiments, identifies points of commonality and disagreement among the different perspectives within sociology, and elaborates on the rationales of each. It helps experimental sociologists find appropriate designs for answering specific research questions while alerting them to the challenges. Offering more than just a guide, this book explores both the historical roots of experimental sociology and the cutting-edge techniques of rigorous sociology. It concludes with a tantalizing peek into the future and provides a roadmap to the exciting prospects and uncharted territories of experimental sociology.

The Philosophy and Methodology of Experimentation in Sociology
Davide Barrera, Università degli Studi di Torino, Italy,Klarita Gërxhani, Vrije Universiteit, Amsterdam,Bernhard Kittel, Universität Wien, Austria,Luis Miller, Institute of Public Goods and Policies, Spanish National Research Council,Tobias Wolbring, School of Business, Economics and Society at the Friedrich-Alexander-University Erlangen-Nürnberg
This chapter focuses on different research designs in experimental sociology. Most definitions of what constitutes an experiment converge on the idea that the experimenter "control" the phenomenon under investigation, thereby setting the conditions under which the phenomenon is observed and analyzed. Typically, the researcher exerts experimental control by creating two situations that are virtually identical, except for one element that the researcher introduces or manipulates in only one of the situations. The purpose of this exercise is to observe the effects of such manipulation by comparing it with the outcomes of the situation in which the manipulation is absent. One way to look at how the implementation of this rather straightforward exercise produces a variety of designs is by focusing on the relationship that experimental design bears with the theory that inspires it. Therefore, we begin this chapter with a discussion of the relationship between theory and experimental design before turning to a description of the most important features of various types of designs. The chapter closes with a short overview of experiments in different settings such as laboratory, field, and multifactorial survey experiments.

Methodological Challenges of Experimentation in Sociology

Experimental practices developed in different scientific disciplines following different historical trajectories. Thus, standard experimental procedures differ starkly between disciplines. One of the most controversial issues is the use of deception as a methodological device. Psychologists do not conduct a study involving deception unless they have determined that the use of deceptive techniques is justified by the study’s significant prospective scientific, educational, or applied value and that effective nondeceptive alternative procedures are not feasible. In experimental economics it is strictly forbidden and a ban on experiments involving deception is enforced by all major economic journals. In the sociological scientific community, there is no clear consensus on the matter. Importantly, the disagreement is sometimes based on ethical considerations, but more often it is based on pragmatic grounds: the anti-deception camp argues that deceiving participants leads to invalid results, while the other side argues that deception has little negative impact and, under certain conditions, can even enhance validity. In this chapter, we first discuss the historical reasons leading to the emergence of such different norms in different fields and then analyze and separate ethical and pragmatic concerns. Finally, we propose some guidelines to regulate the use of deception in sociological experiments.

Sociology is a science concerning itself with the interpretive understanding of social action and thereby with a causal explanation of its course and consequences. Empirically, a key goal is to find relations between variables. This is often done using naturally occurring data, survey data, or in-depth interviews. With such data, the challenge is to establish whether a relation between variables is causal or merely a correlation. One approach is to address the causality issue by applying proper statistical or econometric techniques, which is possible under certain conditions for some research questions. Alternatively, one can generate new data with experimental control in a laboratory or the field. It is precisely through this control via randomization and the manipulation of the causal factors of interest that the experimental method ensures – with a high degree of confidence – tests of causal explanations. In this chapter, the canonical approach to causality in randomized experiments (the Neyman–Rubin causal model) is first introduced. This model formalizes the idea of causality using the "potential outcomes" or "counterfactual" approach. The chapter then discusses the limits of the counterfactual approach and the key role of theory in establishing causal explanations in experimental sociology.

Field experiments have a long tradition in some areas of the social and behavioral sciences and have become increasingly popular in sociology. Field experiments are staged in "natural" research settings where individuals usually interact in everyday life and regularly complete the task under investigation. The implementation in the field is the core feature distinguishing the approach from laboratory experiments. It is also one of the major reasons why researchers use field experiments; they allow incorporating social context, investigating subjects under "natural" conditions, and collecting unobtrusive measures of behavior. However, these advantages of field experiments come at the price of reduced control. In contrast to the controlled setting of the laboratory, many factors can influence the outcome but are not under the experimenter’s control and are often hard to measure in the field. Using field experiments on the broken windows theory, the strengths and potential pitfalls of experimenting in the field are illustrated. The chapter also covers the nascent area of digital field experiments, which share key features with other types of experiments but offer exciting new ways to study social behavior by enabling the collection large-scale data with fine-grained and unobtrusive behavioral measures at relatively low variable costs.

This chapter focuses in more detail on the role of incentives in experimental sociology. Providing the right incentives in an experiment is an important precondition for drawing valid inferences. This is a predominant view in experimental economics based on the induced-value theory assuming that monetary incentives override any other human motivation in laboratory economic experiments. A slightly less demanding assumption is that subjects can be incentivized by monetary payoffs but are also motivated by other-regarding preferences or reciprocity. On the other hand, psychologists focus on motivations that subjects bring into the laboratory as a predisposition to behavior and on the framing of the situation. Sociological research takes elements from both perspectives and emphasizes institutional, cultural, and social determinants of human behavior. An important theoretical framework for experimental work is sociological work on framing. According to sociological framing theories, subjects interpret the situation in terms of the given cues and select an action that is appropriate to the situation. The chapter discusses the implications of these three views on the design of experiments in sociology.
