I began as the secretary/treasurer for the History of Economics Society (HES) in 1999. Prior to my appointment, I had attended one conference and really didn’t know much about the society. My colleague Jim Wible (who was an active member) asked me if I would be interested and essentially pushed my name forward (there probably were not any other takers at the time). I was handed a paper ledger, a notebook of minutes, another collection of materials that were passed down from president to president, and $50,000 in bank deposits.

Using comprehensive account-level data, we separate Chinese retail investors into 5 groups and document strong heterogeneity in trading dynamics and performances. Retail investors with smaller account sizes cannot predict future returns correctly, display daily momentum patterns, fail to process public news, and show overconfidence and gambling preferences, while retail investors with larger account balances predict future returns correctly, display contrarian patterns, and incorporate public news in trading. Using performance measures established in previous literature, we find that smaller retail investors suffer from poor stock selection abilities and trading costs, while large retail investors’ stock selection abilities are offset by trading costs.

Maternal obesity may trigger long-term neurodevelopmental disorders in offspring. Considering the benefits of the Brazil nut (Bertholletia excelsa H.B.K.), a rich source of nutrients such as selenium, this study aimed to evaluate its effect on the behavior of obese rat offspring and its relationship with oxidative stress. From 60 days of age until weaning, female Wistar rats were fed a high-fat diet (mHF) or an HF diet supplemented with 5% Brazil nut (mHF/BN), while control mothers (mCTL) were fed a standard diet or a standard diet supplemented with 5% Brazil nut (mBN). Male pups received a standard diet throughout life and, at 30 and 90 days old, were subjected to behavioral tasks to evaluate anxiety and cognition. Biochemical evaluations were performed at 90 days of age. No alterations were observed in the anxiety behavior of the offspring. However, the offspring of the mHF group (oHF) exhibited impaired short-term memory at 30 and 90 days of age and impaired long-term memory at 30 days. Short-term memory impairment was prevented by Brazil nuts in young rats (30 days). While the serum selenium concentration was reduced in the oHF group, the serum catalase concentration was reduced in all groups, without changes in lipid peroxidation or protein carbonylation. Brazil nut maternal diet supplementation prevented short- and long-term cognitive impairment in the offspring, which may be related to the selenium levels.

Opinions vary in Japan on whether smoking is deviant today, but the behavior, once widely accepted, faces increasing regulation. Recent reforms, moving beyond reliance on nonsmokers' tolerance and smokers' etiquette, impose stricter and more detailed rules on smoking, along with penalties for noncompliance. As the Japanese government's promotional materials note, the reforms move “from manners to rules” (manā kara rūru e). The evolution of Japan's smoking regulations exemplifies a shift toward more legalistic modes of social control. Historically, Japanese governance relied on non-binding “soft law,” administrative guidance, and societal cooperation. Legalistic governance, in contrast, hinges on formal rules and proceduralized enforcement mechanisms. This article, drawing on twenty-eight interviews and qualitative analysis of policy deliberations, advocacy organization documents, court rulings, and Japanese news coverage, traces how societal actors contributed to this legalistic turn. Tobacco control advocates filed lawsuits, pursued voluntary changes through local activities, and provided information subsidies to policymakers while lobbying for local and national reforms. They thereby helped de-normalize smoking and render it regulatable. By uncovering bottom-up drivers of legalistic governance and the strategies through which societal actors influence regulatory style, this paper contributes to scholarship on governance, policy diffusion, and law and social change.

An enhanced wideband tracking method for characteristic modes (CMs) is investigated in this paper. The method consists of three stages, and its core tracking stage (CTS) is based on a classical eigenvector correlation-based algorithm. To decrease the tracking time and eliminate the crossing avoidance (CRA), we append a commonly used eigenvalue filter (EF) as the preprocessing stage and a novel postprocessing stage to the CTS. The proposed postprocessing stage can identify all CRA mode pairs by analyzing their trajectory and correlation characteristics. Subsequently, it can predict corresponding CRA frequencies and correct problematic qualities rapidly. Considering potential variations in eigenvector numbers at consecutive frequency samples caused by the EF, a new execution condition for the adaptive frequency adjustment in the CTS is introduced. Finally, CMs of a conductor plate and a fractal structure are investigated to demonstrate the performance of the proposed method, and the obtained results are discussed.

Mollusc and crustacean consumption in the first 1000 d may improve maternal and child health by providing essential nutrients. However, in some contexts, molluscs and crustaceans have been associated with allergies and environmental contamination, potentially leading to adverse health and development outcomes. It is unclear whether the health benefits of consuming molluscs and crustaceans, collectively classified as shellfish in nutrition, are outweighed by the potential risks to pregnant women and children. We conducted a scoping review (PROSPERO: CRD42022320454) in PubMed, Scopus and EBSCO Global Health of articles published between January 2000 and March 2022 that assessed shellfish consumption during pregnancy, lactation or childhood (0–2 years) in relation to maternal health, child health or child development. A total of forty-six articles were included in this review. Overall, shellfish consumption was associated with higher biomarkers of environmental contaminants, with mercury being the most studied and having the strongest evidence base. The limited research on nutritional biomarker status shows an association between shellfish consumption and iodine status. Preterm birth was not associated with shellfish consumption, but newborn anthropometry showed mixed results, with several studies reporting lower birth weight with higher shellfish consumption. The few studies that examined child development and maternal health outcomes reported no significant associations. This review revealed trade-off health risks and benefits with inclusion of molluscs and crustaceans in the dietary patterns of mothers and young children. More research is needed to understand how these aquatic animal-source foods may be safely consumed and leveraged for improving human nutrition.

Across the globe, welfare conditionality and sanctioning increasingly permeate social welfare programs. Paternalism is one of the key normative rationales invoked when both scholars and politicians debate the legitimacy of this reform. With a view to bringing the scholarly and political debates into closer conversation with each other, this paper examines how paternalism manifests in political debate. We systematically analyse the paternalist arguments made by Australian federal parliamentarians in favour of the virtually identical 2017 and 2018 policy proposals to drug test welfare recipients, both of which resulted in a stalemate. We find that paternalistic arguments primarily employed soft, weak, and welfare paternalism, with heavy emphasis on the purported benefits of the intervention, limited emphasis on the issue of personal liberty, and noticeable silence about autonomy and consent. These findings shed light on the scholarly features of paternalism that are obscured in contemporary political discourse. This analysis can direct political philosophers to features of paternalism that need more attention as well as suggest ways that drug and welfare policy advocates may engage more effectively with paternalist arguments.

Several post-independence African states have opted for constitutional democracies in response to various governance challenges. Most of these constitutions espouse values of constitutionalism, such as the rule of law, human rights and citizenship. This article interrogates the concept of constitutionalism, examines its pillars and values, and reflects on how Africa's constitutions mirror them. Its thesis is that a constitutional government does not necessarily approximate constitutionalism. The article argues, with evidence, that many states possess constitutions but fall short in practising constitutionalism. It calls on these states to embark on institutional reforms and to pursue good governance that improves the living standards of their citizens.

Amidst the upheavals of the First World War, a considerable number of prisoners of war from the Ottoman Empire found themselves in Russia, resettled primarily in the central regions of the Russian Empire. The regions of Volga, Siberia, Ural, and Western Siberia played host to Ottoman prisoners, who were accommodated in camps and barracks across cities and rural areas. Over time, a noteworthy migration led some prisoners to the territory of modern Kazakhstan, with cities like Samara, Orenburg, and Omsk serving as pivotal points before further dispersion into the central regions of Kazakhstan. As a result, Ottoman citizens found themselves under suspicion and were dispersed akin to prisoners. The Semirechye Oblast (Zhetisu region) emerged as a focal point where both Ottoman subjects and prisoners of war were dispersed during this tumultuous period. This article investigates the political and social dynamics, as well as the fate, of Turkish prisoners of war and citizens within the Semirechye Oblast during the war. The analysis delves into the status of Ottoman Empire subjects who acquiesced to the authority of the Russian Empire, offering insights into the lives of prisoners of war in this specific region.

La récente parution de l’édition complète des Maqālāt ahl al-qibla d'Abū l-Qāsim al-Balḫī (m. 319/931) ouvre de nouvelles perspectives sur l'histoire de la construction de la tradition doxographique musulmane. À travers une comparaison des Maqālāt d’al-Balḫī et des Maqālāt al-islāmiyyīn wa-ḫtilāf al-muṣallīn d’Abū l-Ḥasan al-Ašʿarī (m. 324/935-6), cet article démontre qu'al-Balḫī est la source directe d'al-Ašʿarī sur les šīʿites. Cette nouvelle donnée permet dès lors d'analyser l’évolution du genre des maqālāt aux IIIe/IXe-IVe/Xe siècles, notamment son rapprochement progressif avec une pratique spécifiquement hérésiographique.

Varietal identification plays a pivotal role in viticulture for several purposes. Nowadays, such identification is accomplished using ampelography and molecular markers, techniques requiring specific expertise and equipment. Deep learning, on the other hand, appears to be a viable and cost-effective alternative, as several recent studies claim that computer vision models can identify different vine varieties with high accuracy. Such works, however, limit their scope to a handful of selected varieties and do not provide accurate figures for external data validation. In the current study, five well-known computer vision models were applied to leaf images to verify whether the results presented in the literature can be replicated over a larger data set consisting of 27 varieties with 26 382 images. It was built over 2 years of dedicated field sampling at three geographically distinct sites, and a validation data set was collected from the Internet. Cross-validation results on the purpose-built data set confirm literature results. However, the same models, when validated against the independent data set, appear unable to generalize over the training data and retain the performances measured during cross validation. These results indicate that further enhancement have been done in filling such a gap and developing a more reliable model to discriminate among grape varieties, underlining that, to achieve this purpose, the image resolution appears to be a crucial factor in the development of such models.

The Falkland Shelf is a highly productive ecosystem in the Southwest Atlantic Ocean. It is characterized by upwelling oceanographic dynamics and displays a wasp-waist structure, with few intermediate trophic-level species and many top predators that migrate on the shelf for feeding. One of these resident intermediate trophic-level species, the Patagonian longfin-squid Doryteuthis gahi, is abundant and plays an important role in the ecosystem. We used two methods to estimate the trophic structure of the Falkland Shelf food web, focusing on the trophic niche of D. gahi and its impacts on other species and functional groups to highlight the importance of D. gahi in the ecosystem. First, stable isotope measurements served to calculate trophic levels based on an established nitrogen baseline. Second, an Ecopath model was built to corroborate trophic levels derived from stable isotopes and inform about trophic interactions of D. gahi with other functional groups. The results of both methods placed D. gahi in the centre of the ecosystem with a trophic level of ~ 3. The Ecopath model predicted high impacts and therefore a high keystoneness for both seasonal cohorts of D. gahi. Our results show that the Falkland Shelf is not only controlled by species feeding at the top and the bottom of the trophic chain. The importance of species feeding at the third trophic level (e.g. D. gahi and Patagonotothen ramsayi) and observed architecture of energy flows confirm the ecosystem's wasp-waist structure with middle-out control mechanisms at play.
