The current study examined the relationship between interest, the home environment, and young Chinese children’s development of English as a second/foreign language in Hong Kong. Two hundred and seventy-four Hong Kong kindergartners were assessed on their interest in learning English and their English language skills (i.e., expressive and receptive vocabulary). Their parents completed questionnaires eliciting family socio-economic status, parental beliefs, and home learning environment. The results indicated that (1) interest was related to children’s English language abilities after controlling for children’s gender, non-verbal intelligence, and kindergarten type; (2) parents’ beliefs about their child’s English ability and self-efficacy were related to children’s interest in learning English; and (3) interest uniquely contributed to children’s English language ability in the home environment. The present findings provide evidence of the active role that children play in their second/foreign language development and highlight the significant influence of parental beliefs on children’s interest in learning English.

An (ongoing) interrogation of colonial wrongdoing is important for debates on decolonisation, restorative justice, racial and gender equality and global political and socio-economic equality. This article presents a theoretical study of colonialism’s legal-political injustices and aims to (re)turn the discussion on colonialism to the field’s most powerful insight, i.e. that of of epistemic violence and injustice. This article also suggests that the reach of this historical injustice went much further than the politics of autonomy, usurpation of territorial rights, political disenfranchisement and resource appropriation. To address the question of colonialism’s distinctiveness as a political mission, which has been discussed in recent debates within analytic philosophy, it argues that colonialism’s epistemic injustice, which denied the very existence and the traditions of the colonised, is the foundational and distinctive feature of colonialism as a political system and which drives its continued impact to this day.

La Milpa, situated in northern Belize, stands out as one of the region's largest archaeological sites, having served as the capital of an ancient Maya city-state. Its significance is indicated by extensive monumental architecture, with the epicenter covering approximately 8.8 ha. The site's corpus of monuments, comprising 23 stelae and several altars, underscores its prominence in northern Belize, rivaling the corpora of sites such as Nim li Punit and Caracol. Despite its remote location, La Milpa has garnered the attention of researchers, particularly since the first modern survey of the site in 1988. Subsequent studies—in particular, that by Nikolai Grube in the 1990s—has provided detailed analyses of the site's corpus of carved monuments. Recent efforts, including epigraphic documentation in 2019, serve to enhance our understanding of La Milpa's dynastic history through traditional epigraphic and computational photographic methods. Utilizing field observations, raking light photography, and 3D photogrammetric models, we have refined previous analyses and provide new insights into the iconography and textual segments of the monuments. Here, we present the results of these recent efforts as well as our new analyses of a selection of monuments.

Past hydrogeological processes and human impacts may exert substantial memory effects on today’s groundwater systems. Thorough characterization of such long-term processes is required for scientists and policymakers to predict the hydrogeological impacts of land management options. Especially in data-scarce areas, historical data are essential to unravel long-term hydrogeological processes, which could not be identified by short-term fieldwork or model simulations alone. However, historical data are often overlooked or only used as background information in most hydrogeological studies. We show that the combination of historical reports and quantitative data yields major insights in the hydrogeological system of Curaçao, a small semi-arid Caribbean island. Reconstructing the island’s groundwater conditions over the past 500 years revealed that deforestation and excessive abstraction has had a detrimental effect on the island’s groundwater reserves. Historical notes and data revealed major signs of seawater intrusion, especially during abstraction peaks in the island’s industrial era. Intrusion effects are still observed locally on the island today, but additional groundwater recharge by waste water has caused freshening elsewhere. We hypothesize that the observed aquifer replenishment locally enhances submarine groundwater discharge, flushing accumulated nutrients and pollutants towards Curaçao’s fringing coral reefs. We expect that this study’s insights motivate more hydrogeologists to use historical reports and data in future studies.

Although dietary factors have been examined as potential risk factors for liver cancer, the evidence is still inconclusive. Using a diet-wide association analysis, our research evaluated the associations of 126 foods and nutrients on the risk of liver cancer in a Chinese population. We obtained the diet consumption of 72,680 women in the Shanghai Women’s Health Study using baseline dietary questionnaires. The association between each food and nutrient and liver cancer risk was quantified by Cox regression model. A false discovery rate of 0.05 was used to determine the foods and nutrients which need to be verified. Totally 256 incident liver cancer cases were identified in 1,267,391 person-years during the follow-up duration. At the statistical significance level (P ≤ 0.05), higher intakes of cooked wheaten foods, pear, grape and copper were inversely associated with liver cancer risk, while spinach, leafy vegetables, eggplant and carrots showed the positive associations. After considering multiple comparisons, no dietary variable was associated with liver cancer risk. Similar findings were seen in the stratification, secondary and sensitivity analyses. Our findings observed no significant association between dietary factors and liver cancer risk after considering multiple comparisons in Chinese women. More evidence is needed to explore the associations between diet and female liver cancer occurrence.

Cape Welchness is an uncovered ice area on Dundee Island (north-east of the Antarctic Peninsula), mostly covered by Holocene-age glacial-glaciomarine deposits of up to 70 m in depth. In some areas, rocks from the Trinity Group and the Gustav Group outcrop. Syngenetic cryounits with an active layer development of 0.8 m and ice content ranging from 6% to 15%, increasing with depth, have been detected. Epigenetic units develop an active layer of up to 1.25 m (6–16% ice content), with similar depth values. Along the coastal zone, cryopeg reaches nearly 8 m in depth, alternating between ice, fresh water and saline water. The low and high plains exhibit extensive areas of open talik. In the low plain, a suprapermafrost summer aquifer with a thickness of 1.25–1.50 m develops. Glacial-fed creeks discharge 98% of the water input, while snow-fed creeks contribute only 0.04 Hm3/month. The ponds are divided into those fed by glaciers (linked to open talik) and those fed by precipitation (linked to closed talik). Creeks have an average salinity of 198 mg/l, lakes 190 mg/l and groundwater 223 mg/l. This study focuses on the area of the new Petrel Base, designed to enhance Argentine logistics.

We obtain an adaptation of Dade’s Conjecture and Späth’s Character Triple Conjecture to unipotent characters of simple, simply connected finite reductive groups of type $\mathbf {A}$, $\mathbf {B}$ and $\mathbf {C}$. In particular, this gives a precise formula for counting the number of unipotent characters of each defect d in any Brauer $\ell $-block B in terms of local invariants associated to e-local structures. This provides a geometric version of the local-global principle in representation theory of finite groups. A key ingredient in our proof is the construction of certain parametrisations of unipotent generalised Harish-Chandra series that are compatible with isomorphisms of character triples.

Diversified farming systems appear to be one means of meeting the sustainability challenges facing livestock farming systems and of facilitating the renewal of future generations of farmers in a context of climatic, economic and social change. However, although work seems to be an essential issue for livestock farms, few studies have explored the impact of on-farm diversity on work. This study aims to fill the gap in our understanding of the various ways in which on-farm diversity affects work. We applied a framework combining six dimensions of work with three forms of on-farm diversity (diversity of management entities, diversity of farming activities, diversity of workers) to six studies that had been conducted previously on livestock farms. Our results highlight a wide range of links between on-farm diversity and work. We show that on-farm diversity affects various dimensions of work in multiple ways, which can be both positive and negative. For example, while there may not be a strict and clear relation between on-farm diversity and workloads, diversity provides flexibility for organizing the distribution of working time. Moreover, on-farm diversity seems to more frequently reinforce the meaning of work for farmers. Our results also show that there are multiple interactions between the six dimensions of work studied. Our study points to the need for a comprehensive approach to understanding the multifaceted and interconnected nature of work dimensions in diversified farming systems. Further research is recommended to explore these relationships more deeply to support sustainable and attractive diversified farming systems.

This research investigates the Environmental Kuznets Curve (EKC) hypothesis within Brazil’s soy transportation sector. It aims to determine if CO2 emissions from soy transport show an “Inverted-U” or “N” shaped relationship with income from 2002 to 2017. Using a mathematical optimization model and System GMM for analysis, the study finds an “N” shaped EKC, indicating emissions initially increase, decrease, and then rise again with income. This suggests long-term environmental damage from sector growth, highlighting the need for targeted measures to mitigate emissions and enhance operational productivity, such as investments in intermodal transport and road efficiency improvements.

Knowledge of Antarctic permafrost is mainly derived from the Antarctic Peninsula and Victoria Land. This study examines the 2019–2023 temperature and humidity conditions, distribution and development of polygonal terrain and the origin of ground ice in soils of the Untersee Oasis. In this region, the surface offset (MAAT ≅ MAGST) and the thermal offset (MAGST ≤ TTIT) reflect the lack of vegetation, absence of persistent snow and a dry soil above the ice table. The mean annual vapour pressure at the ground surface is approximately ~2× higher than in the air but is ~0.67× lower than at the ice table. The size of polygons appears to be in equilibrium with the ice-table depth, and numerical modelling suggests that the depth of the ice table is in turn in equilibrium with the ground surface temperature and humidity. The ground ice at the ice table probably originates from the partial evaporation of snowmelt that infiltrated the dry soil column. As such, the depth of the ice table in this region is set by the water vapour density gradient between the ground surface and the ice-bearing ground, but it is recharged periodically by evaporating snowmelt.

The Vietnam Draft Lotteries, which randomly assigned men to military service, enable researchers to assess the long-term effects of interracial contact on racial attitudes. Using a new draft status indicator for respondents to the General Social Surveys 1978–2021, we show that white men who were selected for the draft subsequently expressed less negative attitudes toward Black people and toward policies designed to help them. These effects are apparent only for cohorts that were actually drafted into service, suggesting that interracial contact during military service led to attitude change. These findings have important implications for theories of political socialization and prejudice reduction.

Attention has been shown to modulate the visual evoked potential (VEP) recorded to reversing achromatic patterns. However, the chromatic onset VEP appears to be robust to attentional shifts. Functional magnetic resonance imaging (fMRI) responses to both chromatic and achromatic reversing patterns are also affected by attention. Resolution and comparison of these results is problematic due to differences in presentation mode, stimulus parameters, and the source of the response. Here, we report the results of experiments using comparable perceptual contrasts, pattern reversals, and a co-extensive and highly demanding multiple object tracking (MOT) task while exploring the effects of attentional modulation across both the chromatic (L − M) and (S − (L + M)) and the achromatic visual pathways. Our findings indicate that although achromatic VEPs are modulated by attention, chromatic VEPs are more robust to attentional modulation, even when using comparable stimulus presentation modes and in the presence of a highly demanding distractor task. In addition, we found that the majority of the modulation appears to be from a relative decrease in response due to the distractor task rather than a relative increase in response during heightened attention to the stimulus.

This paper presents a flexible SiGe monolithic microwave integrated circuit (MMIC) chipset for 120 GHz ultra-wideband frequency-modulated continuous wave radar systems. The highly integrated chipset is implemented with multiple-input and multiple-output radar in mind which leads to transmit and receive MMICs with four integrated channels in each chip. The transmitter achieves an output power of 12.9 dBm with a total power consumption of only 403 mW. The receiver chip incorporates a sub-harmonic approach for suppression of leakage radiation at 120 GHz through a receive channel. Both chips integrate active multiplier chains that are driven by a third reference dual band voltage-controlled oscillator (VCO) MMIC that can deliver an output at center frequencies of 15 or 30 GHz. The reference VCO MMIC demonstrates relative tuning ranges of 32%.
