The troublesome weed Johnsongrass [Sorghum halepense (L.) Pers.] is predicted to expand its range under climate change. In the process, it is likely to become more competitive in corn (Zea mays L.) production areas of the northeastern United States and southern Canada. A replicated greenhouse experiment was conducted to measure interspecific and intraspecific competition between an S. halepense biotype from central New York State (northern range edge) and corn under drought and well-watered conditions. Drought stress significantly reduced the biomass and height of corn and S. halepense in both rounds of the experiment (P < 0.001). Drought stress increased the root-to-shoot ratio of S. halepense (P < 0.001) and reduced the root-to-shoot ratio of corn (P < 0.001). In one run of the experiment, corn produced 19.3% more aboveground biomass (P < 0.001) and 6.6% more height (P < 0.001) when competing with an S. halepense plant (interspecific competition) than when competing with a second corn plant (intraspecific competition). Drought conditions increased the advantage of corn plants grown under interspecific relative to intraspecific competition (P = 0.012). In that round of the experiment, biomass of S. halepense was 12.9% higher under intraspecific competition than interspecific competition in the well-watered treatment and 15.5% higher under intraspecific competition than interspecific competition in the drought treatment (main effect of competition, P = 0.002). Differences between competition treatments were smaller in the other round of the experiment (P > 0.05). Our findings suggest that the New York S. halepense biotype used in this study may not be as competitive as biotypes found in this weed’s range core in more southern regions of the United States. However, anticipated effects of climate change may increase the abundance and competitiveness of this species in the northeastern United States.

Scholars have extensively studied the diffusion of criminal laws across the American states, and this paper examines an overlooked story of penal diffusion: the mid-twentieth-century spread of habitual offender laws. These laws, which escalated sentences for repeat offenders, proliferated across the states decades before the enactment of the three-strikes laws to which they bore remarkable resemblance. But whereas prior research has traced the legislative diffusion of habitual offender laws, this article alternatively explores how state courts’ interpretations of habitual offender laws diffused across jurisdictions. Using an innovative theoretical framework blending judicial diffusion research with literatures in neo-institutional theory, this article reveals how state courts borrowed legal decisions from other states to interpret, legitimize, and alter laws within their own jurisdictions. This reveals how state courts can shape the trajectory of legislative diffusion in enduring and profound ways. This study’s unique theoretical framework uses the history of habitual offender laws as a case study to explore underappreciated features and dynamics of the diffusion process that have shaped the development of American criminal law.

This article presents an analytical framework for studying implementation failure in minimum income programs targeted against poverty and applies it to a case study focused on the recent introduction in Spain of the first national minimum income programme, the Minimum Living Income (MLI). The framework combines two criteria (the type of agent potentially triggering failure, and the type of administrative challenge) to produce four types of implementation problems in targeted minimum income schemes: identification failure, administrative incapacity, nontake-up, and overpayments. We apply this framework in the case of MLI by conducting an exhaustive review of empirical research on its implementation problems. This evidence suggests that the special political circumstances in which the MLI was approved, some features of its design, and its insertion into a complex institutional landscape of regional minimum incomes, explain part of these problems. We conclude with some final remarks and recommendations.

This Review has occasionally taken note of the passing of individuals who have made seminal contributions to the public international law of international trade.1 When Frieder Roessler died on 25 July 2024, the editors undertook to memorialize Frieder's legacy with a Symposium about Frieder the international civil servant, Frieder the scholar and teacher, Frieder the institution builder in advocacy for the legal rights of developing countries, and Frieder the friend to admirers around the world and over the course of several decades.

How can populist authoritarian incumbents justify remaining in power when the golden age they promised remains unrealized? We argue that audiovisual products such as videos are particularly suited to enlivening the histories that so many populists evoke in seeking to legitimize their rule. Political science’s traditional focus on speech-based legitimation, however, leaves audiovisual tools largely overlooked. The few studies that do engage these tools test for audience effects, but the content itself and the political strategies behind its curation and dissemination remain undertheorized. By adding an audiovisual lens to studies of authoritarian legitimation, we identify a regime durability strategy we term selective revivification. We specify the cognitive and affective characteristics of videos that quickly communicate information-dense, emotionally evocative messages, arguing that they engagingly distill specific historical elements to portray incumbent rule as not just legitimate but also necessary. In advancing our argument, we construct an original dataset of all existing narration-based YouTube videos shared by six regime institutions in Turkey from the establishment of YouTube in 2005 to 2022 (n = 134). We use quantitative analysis to identify when video usage emerges as a strategy, as well as patterns of dissemination and content elements. We then use intertextual analysis to extract common historical themes and production techniques. The audiovisual tools we specify and the selective revivification strategy they enable fill gaps in studies of authoritarian legitimation while adding to political scientists’ toolkits for wider inquiry.

Individuals with childhood experience of out-of-home care (OHC) face elevated risks of criminal behavior and poor mental health compared with the majority population. Evidence on how trajectories of offending and psychiatric disorders covary among individuals with experience of OHC is needed. This study is based on a cohort of 14,608 individuals (n = 1,319 with OHC experience) born in the Stockholm metropolitan area in 1953 (49% women) from birth to age 63 (2016). Group-based multi-trajectory modeling among those with at least one offense or psychiatric disorder (40.5% of the men, 16.6% of the women) identified four co-occurring trajectories for both sexes. Multinomial regression analyses showed that adolescent OHC placement, particularly in institutions and for behavioral reasons, was linked to higher odds of early-adulthood-limited or decreasing offending and psychiatric trajectories. Most individuals recover from offending and psychiatric disorders by retirement, but placed individuals in particular remain at high risk for offending, alongside psychiatric disorders, throughout early adulthood. Early assessment and tailored attention to needs and risk levels is important when designing long-term care services to mitigate this. Research on underlying mechanisms, and on collaboration between the welfare, justice, and psychiatric care systems, can help to design effective intervention strategies and policies.

The various meanings of ‘legitimacy’ – Constitution-making procedure as a tool to achieve the right content of a new constitutional document – The effect of the procedure on the actual social and political context – Trade-offs between the various conceptions of legitimacy – Inherent tensions between transparency and political compromise, and between inclusivity and elite support – Direct democratic involvement aggravating polarisation – When the time is not ripe for constitution-making, recommended substitute strategies – Various procedural options: popular drafting, constituent assemblies, ordinary parliaments, expert bodies, roundtables, referenda – The dangers of (Kelsenian) constitutional revolutions

Over the past decade, several multi-institutional research consortia have formed within the North American pediatric surgical community. In this article, we describe our experience with the creation and implementation of the Eastern Pediatric Surgery Network, a large and comprehensive research consortium designed to produce a wide array of high-quality clinical studies within our subspecialty. In 2020, a vision statement and rules of governance were established at thirteen academic pediatric surgery divisions in the eastern United States. The research consortium was organized based on four major pillars, namely legal ownership of aggregate data, horizontal leadership structure, mandatory participation in adopted studies, and a broad research portfolio that encompasses the full breath of the specialty. Over the past five years, the number of research projects has dramatically expanded over time and includes participation from 24 different medical centers. Despite a lack of dedicated sponsored extramural support for most projects, there have been 28 abstracts presented at national conferences and 12 manuscripts published in peer-reviewed journals. It is our hope that sharing our experience with creating this organization can help to inform others interested in establishing the academic infrastructure to engage in multi-institutional, evidence-based clinical research in other medical specialties and beyond.

Grandiose delusions have received comparatively little attention in the literature and there is limited empirical evidence assessing the efficacy of cognitive behaviour therapy for psychosis (CBTp) for individuals with grandiose beliefs. This case study presents Noah, a 23-year-old referred to our Early Intervention Service with persistent grandiose beliefs alongside other psychotic experiences. Noah received 26 sessions of CBTp. Scores on measures of perseverative thinking, delusional distress and conviction, wellbeing, and daily functioning were completed at baseline, mid-therapy, end of therapy, and at follow-up 12 weeks after the end of therapy. Results demonstrated improvement across all measures, particularly preservative thinking about beliefs. Improvement in all but one outcome was not only sustained but continued to increase at follow-up. This is one of few known reports on using CBTp with an individual with current grandiose delusions.

This study presents the first record of Miyalachnus sorini Kanturski & Lee, 2024 (Aphididae: Lachninae) in South Korea, thereby extending its known distribution beyond Japan and identifying a new host plant, Prunus sargentii (Rosaceae). We describe diagnostic morphological traits across multiple life stages and compare them with those of Japanese populations. Comparative analyses with Japanese populations demonstrated consistent morphological differentiation, notably elevated ratios of the ultimate rostral segment to antennal segments across multiple morphs in the Korean population, indicating potential ecological adaptation. DNA barcoding using the mitochondrial cytochrome c oxidase I gene revealed low intraspecific divergence (average 0.2%) and interspecific divergence (average 10.5%) between Miyalachnus sp. and M. sorini. Haplotype analysis was performed to investigate the relationship between host plants and cryptic genetic diversity. These findings enhance our understanding of the morphological and genetic diversity of M. sorini and underscore the importance of monitoring its spread for informed pest management strategies.

This article combines book history and urban history to examine the spread of the print trade and facilities for reading in Scotland by the 1820s, using a Scotland-wide trade directory as its main source. The article demonstrates how support for reading, including printers, bookshops and venues for reading, extended far and wide within the Scottish urban hierarchy – from the largest cities to the smallest towns and villages. Variations between different types of towns are discussed, and local case studies provide further insights. The article provides fresh perspectives on Scottish urbanization, through its snapshot view of Scotland’s towns in the mid-1820s.

This paper presents a new problem for the inference rule commonly known as “inference to the best explanation” (IBE). The problem is that uncertainty about parts of one’s evidence may undermine the inferrability of a hypothesis that would provide the best explanation of that evidence, especially in cases where there is an alternative hypothesis that would provide a better explanation of only the more certain pieces of evidence. A potential solution to the problem is sketched, in which IBE is generalized to handle uncertain evidence by invoking a notion of evidential robustness.
