TEM analyses of germinal elements in miracidia and 6-day-old mother sporocysts of Echinostoma caproni were performed. Germinal elements in miracidia are represented by undifferentiated cells and germinal cells. They are localised in the posterior half of the body and form the primordium of the germinal mass, which plays the role of the gonad. In mother sporocysts the germinal mass is located caudally and plays the dual role of the gonad and the uterus. In addition to the undifferentiated cells and germinal cells, it contains embryos, which develop there up to the stage of germinal balls and then move into the sporocyst’s schizocoel, which plays the role of the brood chamber. New germinal cells are formed only by division of undifferentiated cells. No differences between undifferentiated and germinal cells in miracidia and those in sporocysts were found.

Panel data often contain stayers and slow movers. The literature proposes an estimator for the average partial effects (APEs) for this setting without a formal theory. The literature is also silent about inference in the presence of stayers and many slow movers. We contribute to this state of the art. First, we develop an asymptotic theory to guarantee that such an estimator is consistent in the presence of stayers and slow movers. Second, we propose its standard error. Third, we relax the existing assumption to allow for “many” slow movers. Fourth, we generalize the existing estimator. Fifth, we establish that this generalized estimator can achieve larger extents of bias reduction and hence faster convergence rates. Simulation studies demonstrate that the conventional 95% confidence interval covers the true value of the APE with 37%–93% frequencies whereas our proposed one achieves 93%–96% coverage frequencies. Using the U.S. Panel Study of Income Dynamics, we find that estimates of the marginal propensity to consume based on our generalized estimator remarkably differ in values from those of the existing estimators. Moreover, the generalized estimator achieves more than three times as small standard errors as those of the existing robust estimator.

UK food system transformation is urgently needed, but to date, minimal research has investigated ‘blue foods’ probably because they are ethically nuanced. There exists a paradox whereby materially deprived communities should be eating more fish to meet nutritional requirements, yet there is a global ‘red flag’ around global overfishing. New collaborative and creative solutions are, therefore, needed to tackle such food system inequities. By working together, all voices can be equally heard when decisions are being made to improve the system. Similarly, innovation and disruption of established supply chains will enable better access to healthy, affordable and tasty food that will support better nutrition, health and wellbeing. This review paper will present a critique of the ‘The Plymouth Fish Finger’ as a collaborative social innovation case study. Part of the FoodSEqual research project, this exploratory pilot project championed ‘co-production’ approaches to achieve multiple (potential) impacts. This review will critically explore how this social innovation case study has exemplified the complex interplay between factors driving distortions in access to and availability of fish within the local food system. Through collaborative multi-stakeholder (transdisciplinary) processes, using participatory creative methods, new strategies and recommendations for research, practice, action and policy are informed, all of which offer great potential for progressive and transformative systemic (blue) food system change.

A low-profile dual-circularly polarized (CP) antenna array using spiral sequential rotation (SSR) technique is proposed. The array element consists of two stacked CP patches and a double-layer ceramic substrate with high dielectric constant. Dual CP radiations are accomplished by the slender rectangular structures on the radiators, which can excite two orthogonal characteristic modes. An extremely small size of 0.005λ3 (λ is the wavelength in free space for the low bands) and a wide 3-dB axial ratio beamwidth (ARBW) of 206° are achieved. Furthermore, the SSR technique is employed to achieve low cross-polarization level (XPL) within a large scanning angle. Prototype of a 6 × 6 array was fabricated and measured. Experimental results demonstrate that a wide 3-dB AR scanning angle of ± 55° is realized for LHCP as well as RHCP radiation. Additionally, low XPL less than −18.1 dB with gain fluctuation less than 4 dB are achieved over −55° ∼ + 55°. Meanwhile, the array has successfully passed the mechanical test and the thermal vacuum test (−90° ∼ + 90°). All the merits of dual-CP radiation, extremely low profile of 0.06λ, wide 3-dB AR scanning capability, and low XPL make our proposed dual-CP SSR antenna array be attractive candidate for satellite applications.

Research on how cognitive and affective factors shape bilinguals’ moral judgments in their first (L1) and second (L2) languages remains limited. This study advances our understanding of both language-related variables (L2 proficiency, age of onset of L2 acquisition, length of L2 immersion) and nonlinguistic variables (emotional intelligence, executive functions) in relation to the moral judgments and emotional intensity experienced by 90 Chinese–English bilingual speakers. Participants read five moral dilemmas and completed a set of questionnaires and cognitive ability tests. Mixed-effects models revealed no evidence of a moral foreign language effect, raising questions about the robustness of this phenomenon. Specifically, neither language-related variables nor emotional intelligence had a significant effect. However, participants with stronger updating ability made more deontological judgments in both their L1 and L2, while those with better inhibitory control also made more deontological decisions, but only in their L1. These findings offer new insights into the relationship between language and cognition.

Industrial-organizational (I-O) psychology has largely ignored organized labor, both in terms of our research interests and as a potential domain of professional practice. Historically, some I-O psychologists have even engaged in antilabor activities. This article aims to make that history more salient to current members of the profession, help us better understand how and why that schism came about, note the adverse effects on our understanding of organizations and contributing to employee well-being and organizational effectiveness, and highlight associated ethical issues. We offer suggestions on how to address the situation, drawing on examples from the field of industrial relations. We also consider the impact of the current antilabor, antidemocratic US government administration. We conclude by offering some suggested prompts for commentaries to the article.

For a plant as renowned and beloved in China as the plum blossom (meihua 梅花), there is conspicuously little written in English about eating it. However, without understanding the historical affection for consuming plum blossoms, our comprehension of it as a cultural icon misses an important dimension. This article explores the intriguing discourse surrounding plum blossom consumption in three sections. The first section introduces the key concept of qing 清 (“purity”) and its relation to the “poet’s spleen” (shiren pi 詩人脾), which provides a theoretical framework for a relationship between eating it and writing poetry. The second section examines Song-dynasty poems on this eating practice, particularly those by Yang Wanli 楊萬里 (1127–1206) and the Rivers and Lakes poets (jianghu shiren 江湖詩人). Their poetry was closely tied to new developments in the notion of qi 氣 and “poetic spleen” (shipi 詩脾). The third section turns to culinary recipes, primarily from the Rivers and Lakes poet Lin Hong 林洪 (fl. 1224–1263), who promotes qing aesthetics in plum blossom dishes. I argue that the discovery of culinary value in a flower long regarded as more symbolic than edible marks a significant development in Song-dynasty (960–1279) literati culture, aesthetics, intellectual history, and medicine.

In this paper, I explore the millennium-long presence of the chickpea in premodern China by highlighting three key historical moments. The legume had its first rise to prominence as a cosmopolitan “Muslim Bean” in the Mongol Yuan (1271–1368) imperial diet. It then experienced a phase of obscurity, as the most renowned Chinese herbalist, Li Shizhen 李時珍 (1518–1593), conflated it with the pea. A disparate identity of the legume emerged around the same time, as the bean garnered attention from famine relief specialists, consequently transforming into a source of sustenance. The multiple lives of the chickpea were characterized with a common emphasis on its foreignness, drawing connections to various Eurasian cultures beyond China. The plant’s enduring presence, coupled with ongoing allusions to its alienness, makes it a perpetual foreigner in the broad expanse of the Chinese empire.
