Eclipta [Eclipta prostrata (L.) L.] is an important tropical weed that has recently emerged as a problematic weed in dry direct-seeded rice (Oryza sativa L.) (DSR) fields in China. Understanding its seed germination biology and ecology is crucial for developing integrated weed management strategies in the DSR system. Laboratory experiments were conducted to investigate seed germination of E. prostrata seeds under varying environmental conditions. Germination was greatest under alternating temperature regimes of 25/15 to 40/30 C, whereas it wa-s significantly reduced at 20/10 C and completely inhibited at 15/5 C. Germination was also fully suppressed under continuous darkness, indicating strong light dependency. Eclipta prostrata seeds tolerated a broad range of pH values (4 to 10) with germination rates consistently greater than 95%. However, germination declined sharply under osmotic potentials, falling below 2% at −0.6 MPa, and being completely inhibited at −0.7 MPa. Seeds also showed moderate salt tolerance, with 50% inhibition at 150 mM NaCl and no germination at 300 mM NaCl. Exposure to radiant heat (>90 C for 5 min) prevented germination, suggesting residue burning may be an effective control measure. Seedling emergence was highest (100%) on the soil surface but declined steeply with increasing burial depth, with no emergence observed beyond 0.5 cm. Similarly, surface application of wheat (Triticum aestivum L.) straw residue (2 to 6 Mg ha−1) significantly reduced seedling emergence and biomass. These findings provide essential insights into E. prostrata germination ecology and offer practical implications for its integrated management in DSR systems.

We present a philosophically motivated framework for modelling moral agency. In addition to choosing strategies, agents in this framework choose among an appropriate exogenous set of moralities that depends on the context of the game. Further, agents can use mixed strategies to choose their degree of morality. We present two models to demonstrate the framework. In the first model, agents choose between empathy and selfishness while playing prisoner’s dilemma. In the second, agents choose between Kantian universalizing and selfishness while playing a public goods game. For both models, the degree of morality gets determined endogenously rather than assigned parametrically.

Finding the right balance between education and entertainment in science communication has always been a challenge. This essay argues that this balance has often been framed in terms of the correct proportion and use of animation and live-action footage in popular-science media. Clarifying the assumptions behind a century of concerns about animation and science, this historical case study examines the advisory board’s complaints about animation in the Bell System Science Series, which aired in the United States between 1956 and 1964. AT&T interrupted the series mid-stream by switching the creative team from Frank Capra and his production company to Owen Crump at Warner Bros. Studio. Capra’s use of animation in the series featured prominently in this decision. The historical record – as well as Capra’s and Crump’s different aesthetic choices about animation – tells us much about the board’s objections and how they were resolved in production. This essay examines the differences between the two parts of the series to uncover a course correction steered primarily by the scientific advisory board, which reveals a sometimes-fraught relationship between live-action footage and animation in science education that persists even today.

The Deerni copper deposit is one of the largest in Qinghai province, China, with proven copper reserves of 0.556 Mt. To explore new copper orebodies, we conducted a geological study at western Deerni focusing on hydrothermal alterations and ore-controlling structures. Field investigation shows that the deposit is hosted mainly within the central segment of the Deerni ophiolite. Additional hosts include Lower-Permian slate, limestone, gabbro and volcanic rock, as well as the contact zone between granite and slate. Such observations indicate that the Deerni copper deposit is not only associated with the ophiolite, but its formation is also controlled by faults. Alterations including serpentinization, carbonatization, silicification and malachite, and magnetite mineralization occurred along fractures within the wall rocks and surrounding strata. This means the alteration post-dated structural activity that affected the Lower Permian strata in the region. The Deerni copper deposit is controlled by the NW-striking faults. This is evidenced by (1) slate fragments and breccias within the orebodies, (2) saw-toothed boundaries between the orebodies and host rocks, (3) copper ore veinlets and (4) striations and step patterns on the orebody surface and hanging-wall-hosted quartz veins. Mineralization controlled by NW-trending faults suggests a major orebody (‘No. 2’) likely extends to either northwest or southeast. Field investigations along with geophysical and geochemical data, thus predicted the presence of concealed copper orebodies in western Deerni. Subsequent drilling projects have verified this prediction and revealed three concealed orebodies with widths of 7.15–13.87 m and Cu grade of 1.00–11.34 wt.%, adding 10,000 tonnes to the copper reserves.

Current scholarship conceives of courts as victims or targets of populist authoritarians. But can empowered courts facilitate democratic backsliding? This article develops a new framework for understanding the approaches judiciaries take when tackling political corruption and argues that when judges attempt to replace ‘corrupted’ elected branches as the primary representative institution, their actions and rhetoric can enable populist authoritarians to seize power, raising the risk of democratic backsliding. I combine jurisprudence, newspaper archives and interviews to trace the process through which Pakistan’s Supreme Court, committed to playing a representation-replacement role, enabled the military-backed populist Pakistan Tehreek-e-Insaaf to come to power in 2018, and use its powers to reverse Pakistan’s democratic transition. I also probe the political impact of anti-corruption jurisprudence in more established democracies. In doing so, I introduce a typology for understanding approaches courts take when combating corruption, and highlight the threat to democracy that can emerge from judiciaries.

Can we quantify over absolutely every set? Absolutists typically affirm, while relativists typically deny, the possibility of unrestricted quantification (in set theory). In the first part of this article, I develop a novel and intermediate philosophical position in the absolutism versus relativism debate in set theory. In a nutshell, the idea is that problematic sentences related to paradoxes cannot be interpreted with unrestricted quantifier domains, while prima facie absolutist sentences (e.g., “no set is contained in the empty set”) are unproblematic in this respect and can be interpreted over a domain containing all sets. In the second part of the paper, I develop a semantic theory that can implement the intermediate position. The resulting framework allows us to distinguish between inherently absolutist and inherently relativist sentences of the language of set theory.

With formal international organizations (IOs) facing gridlock and informal IOs proliferating, cooperation in the twenty-first century looks different than it did in previous eras. Global governance institutions today also face additional challenges, including a fragmented information environment where publics are increasingly vulnerable to misinformation and disinformation. What do these trends portend for international politics? One way to answer this question is to return to a core ingredient of a well-functioning IO—information provision—and ask how such changes affect efficiency. Viewed through this lens, we see decline in some arenas and adaptation in others. Formal IOs are struggling to retain relevance as their weak policy responses and ambiguous rules create space for competing signals. The proliferation of informal institutions, on the other hand, may represent global governance evolution, as these technocratic bodies are often well-insulated from many political challenges. Yet even if global governance retains functionality, the legitimacy implications of such trends are troubling. IO legitimacy depends in part on process, and from this standpoint, the informational gains of informal governance must be weighed against losses of accountability and transparency. Ultimately, evaluating the normative implications of these trends requires making judgments about the preferred legitimizing principles for global governance.

We investigate a Leslie-type prey–predator system with an Allee effect to understand the dynamics of populations under stress. First, we determine stability conditions and conduct a Hopf bifurcation analysis using the Allee constant as a bifurcation parameter. At low densities, we observe that a weak Allee effect induces a supercritical Hopf bifurcation, while a strong effect leads to a subcritical one. Notably, a stability switch occurs, and the system exhibits multiple Hopf bifurcations as the Allee effect varies. Subsequently, we perform a sensitivity analysis to assess the robustness of the model to parameter variations. Additionally, together with the numerical examples, the FAST (Fourier amplitude sensitivity test) approach is employed to examine the sensitivity of the prey–predator system to all parameter values. This approach identifies the most influential factors among the input parameters on the output variable and evaluates the impact of single-parameter changes on the dynamics of the system. The combination of detailed bifurcation and sensitivity analysis bridges the gap between theoretical ecology and practical applications. Furthermore, the results underscore the importance of the Allee effect in maintaining the delicate balance between prey and predator populations and emphasize the necessity of considering complex ecological interactions to accurately model and understand these systems.

With fintech investment apps providing convenience and round-the-clock access to financial markets on the go, investors are becoming more active in managing their financial lives through smartphones and other mobile devices. However, fintech investing’s role in the financialization of everyday life remains unclear. Combining insights from Foucauldian governmentality and Science and Technology Studies (STS), this article positions fintech brokerage apps as both neoliberal tools in governing investor conduct and as agencements in reconfiguring financial subjectivities. Based on a survey and interviews with lay investors in Singapore, the findings reveal that fintech investors use app-based brokerages as a tool to invest conveniently and at low cost. However, users themselves may resist the financial subjectivities promoted by fintech investing, driven by skepticism towards gamified and other algorithmic app features. They are also motivated by feelings of uncertainty towards fledgling fintech startups and difficulties in their interactions with the app user interface. To mitigate uncertainty, investors adopt various tactics to protect their portfolios.

Evaluation supports the translation of knowledge into practice by systematically assessing what works, for whom, and under what conditions. It generates evidence to guide improvements, inform decision-making, and identify how programs, research studies, or interventions should be scaled. Within a Clinical and Translational Science Award (CTSA) hub, evaluation is typically focused on internal evaluation and administrative functions. However, expanding evaluation to also support efforts based outside of a CTSA hub (i.e., to the larger institution and community), akin to other CTSA cores and services, can support overarching translational goals. This paper outlines the process and benefits of institutionalizing a partnership between clinical and translational science and social science to provide expertise, resulting in evaluation as a translational resource. Herein, we describe developing the Duke Office of Evaluation and Applied Research Partnership, an organizational unit that, by bridging a university’s CTSA hub and interdisciplinary social science institute, expanded the scope and capacity of evaluation to advance clinical and translational science. We outline the specific activities supported by this initiative, facilitators involved in its establishment, and barriers to implementation and success. This model and lessons learned can inform broader opportunities to leverage multidisciplinary evaluation expertise to support clinical and translational science.

This essay reveals the institutional dynamics of hard times in the issue area of human rights. I show that the human rights regime has developed innovative-yet-informal institutions like individuals-based coalitions for the international protection and progressive development of human rights. Yet, as these informal institutions function very much based on, first, the interpersonal relations among their members, and, second, legal instruments that require no further consent by states, the advocacy success of liberal human rights defenders has, in turn, provided a playbook for advocates and governments from the illiberal end of the ideology spectrum. In addition, new human rights advocates in the form of certain private law firms have entered the UN through their pro bono work. They promise valuable resources for a crisis-ridden system but often represent corporate clients with conflicts of interest. Given the imminent risk of ideological capture and illiberal interests in human rights paralyzing the system, I reemphasize the need for regulating access to the human rights global governance institutions.

When Johann Wolfgang von Goethe coined the term ‘world literature’ (Weltliteratur) in 1831, he made it clear that this epoch had begun in his time and, like every epoch, would come to an end. This article is about the end of that epoch and the future of comparative literature in an era after the end of world literature. It is easy to see that we are now living in the era of world literatures. In a world in which, at first sight, literature counts for less and less, it must emphasize its unique selling point: it is the only form of human discourse that has actively expanded the realm of knowledge over several millennia. Only comparative literature, which draws on the most diverse literatures of the world, is able to bring this uniqueness into focus and highlight its social relevance.
