Breast milk (BM) is the only source of iodine and bioactive compounds that influence growth and development in infants. The content of BM may be influenced by maternal body mass index (BMI). The aim of this study was to investigate the effect of maternal weight on BM and cord blood iodine concentrations, growth-related hormones, infant anthropometric measurements. A total of 84 mother-infant pairs participated. Levels of leptin, adiponectin and insulin-like growth factor-I (IGF-I) in postnatal BM and cord blood were analysed by enzyme-linked immunosorbent assay (ELISA), iodine by Sandell-Kolthoff reaction. Dietary iodine intake of women was determined by food frequency questionnaire, and anthropometric measurements of infants at birth and 3 months were evaluated. Dietary iodine intake was found to be similar in normal weight (NW) and overweight/obese (OW/OB) women (p > 0.05). Breast milk iodine concentration (BMIC) was 17.4 μg in NW, 18.2 μg in OB/OW women. Adiponectin in cord blood and IGF-I in BM were higher OB/OW than NW women (p < 0.05). Positive correlations were found between the infant birth weight and adiponectin in BM, between the infant body weight at 3 months and leptin and adiponectin in BM, between the infant birth head circumference and IGF-I in BM (p < 0.05). In multiple linear regression model, leptin and adiponectin in BM had a positive effect on infant body weight (p < 0.05). Maternal BMI may influence infant body weight via leptin and adiponectin in BM and infant head circumference via IGF-I. No relationship was found between maternal BMI and iodine levels and anthropometric measurements of the infant. Longitudinal studies are recommended to understand the effect of BMIC on growth.

In Dong et al. (2022, Journal of Operator Theory 88, 365–406), the authors addressed the question of whether surjective maps preserving the norm of a symmetric Kubo-Ando mean can be extended to Jordan $\ast $-isomorphisms. The question was affirmatively answered for surjective maps between the positive definite cones of unital $C^{*}$-algebras for certain specific classes of symmetric Kubo-Ando means. Here, we give a comprehensive answer to this question for surjective maps between the positive definite cones of $AW^{*}$-algebras preserving the norm of any symmetric Kubo-Ando mean.

This article examines the significance of mobility and transportation infrastructure in the early development of pan-Americanism and the formation of a vision of global transportation in South America in the late nineteenth century. Focusing on the 1880s and 1890s, I explore the connection between transportation and the economic and cultural expansionism of the United States, pan-American debates on intercontinental steamship service and an inter-American railroad, and South American approaches to international transportation, which both included and transcended the Americas. My case study contributes to scholarship on the global history of mobility and transportation by showing how, despite the intention of the United States to establish hemispheric exclusivity and hegemony, transportation became a subject of multilateral cooperation. South American experts and diplomats, I argue, renegotiated and reinterpreted the meaning of pan-American infrastructure, integrating it into a broader vision of global transportation that positioned their countries more prominently in worldwide traffic networks.

In the face of ongoing disruptions to the multilateral trade regime, from deadlock at the WTO to the rise in unilateralism, this contribution examines the role that free trade agreements (FTAs) can play in supporting the adoption of common standards for sustainable development. It does this in three moves: first, it reframes the role of FTAs from sources of obligation and mechanisms of compliance to sites of economic diplomacy where governments can shape international standards through FTA structures; second, it unpacks the relationship between regulation and standards through three case studies (dolphin-safe labelling, automotive standards, and nutrient profiling), identifying means through which FTAs can be leveraged by trade policy actors; third, it draws on these lessons to examine how FTAs can support the uptake of key new standards and quasi-standards for sustainability, in this case, the ISO Net Zero Guidelines. Finally, this contribution reflects on the implications of reappraising the development of world trade law as part of the practice of economic diplomacy.

The Lorne Plateau lava succession of the north-west Grampian Highlands of Scotland is an early component of post-collisional Late Silurian to Early Devonian magmatism in the Orthotectonic Caledonides emplaced in two phases between the Late Silurian (425.0±0.7 Ma U-Pb zircon) and the Siluro-Devonian boundary at ∼419 Ma. Palaeomagnetic study comprising thermal demagnetization and component analysis embracing the time frame of the preserved succession yields a coherent mean direction of magnetization from 58 sites (D/I = 43.7/−47.4°, α95 = 4.0°). A palaeomagnetic fold test is significantly positive with sills intruding unlithified sediment on the island of Kerrera confirming primary remanence. The ∼600 m thick succession has uniform normal polarity throughout permitting correlation with the beginning of a normal polarity chron extending from ∼426 to 403 Ma. The pole position at 2.7°N, 317.3°E (dp/dm = 3.8/5.8°) predicts a palaeolatitude of 26°S and corresponds precisely with remanence in contemporaneous rocks from the Midland Valley of Scotland. Regional palaeofield directions are evaluated in the context of transpressional moulding of the Acadian Orogeny on the Great Glen Fault system (~416−380 Ma).

Business and Human Rights (BHR) scholarship has long recognized the exercise of corporate power as resembling functional sovereignty, advocating for the extension of the rule of law to private actors, establishing accountability regimes, and providing remedies for victims. With the proliferation of binding BHR instruments, such as human rights due diligence legislation, the BHR project finds itself at a critical juncture, where calls for hard obligations are no longer sufficient. Our article, and the broader Symposium, seek to push the boundaries of the discourse by interrogating the legal foundations of private power. Drawing from Law and Political Economy scholarship, we challenge the prevailing notion of ‘governance gaps’ that often frames BHR debates. Rather, we argue that the legal infrastructure itself enables and facilitates the forms of exploitation and structural inequality embedded in the global political economy, leading to predictable patterns of human rights violations. By uncovering the institutional foundations of private power, we also show how efforts to leverage mechanisms of private governance, including human rights due diligence, risk naturalizing corporate power and limiting institutional imagination. However, a critique only focused on institutional design does not sufficiently account for the hardwiring of social relations of global production and the systemic constraints these impose on projects of legal reform. Acknowledging these limitations, we outline two modes of critique: an ‘internal’ critique, which seeks to reimagine institutional frameworks, and an ‘immanent’ critique, which emphasizes the role of collective action and social movements in transforming the underlying social relations of production.

Despite its recent history as a controlled substance, hemp holds promise in contributing to more resilient and sustainable agricultural systems in the United States. Due to reclassification in the 2018 Farm Bill, hemp grown for fiber, grain, and cannabidiol has become an intriguing new crop for many farmers. However, the introduction of hemp into an established agricultural landscape has been met with challenges. This qualitative study explores the experiences of 15 first-year hemp producers in Nebraska, United States. The producers in this study describe the complexities they encountered, including navigating stringent state and federal regulations, securing insurance and loans, and overcoming the public and political stigma associated with cannabis. Additionally, gaps in research and development have contributed to producers' difficulties in accessing credible information, high production costs, and labor shortages. Lastly, farmers expressed having a lack of control options to combat the presence of weeds and insects. Based on these findings, we conclude that, although challenges are to be expected with any new crop, many of the issues encountered by the farmers in the study could be overcome or lessened by research, agricultural extension, and government support. We recommend continued research in hemp production, both in crop production and processing, along with dissemination of meaningful results, to aid producers in building their knowledge base. Additionally, government agencies that oversee hemp production could improve accessibility through revisions to regulations and financial resources for producers.
