Abstract

To characterize the naturalized population of burr medic (Medicago polymorpha L.), a valuable pasture legume, in subtropical Queensland, Australia, a collection of 1747 lines from 107 sites in 11 regions was grown, and 26 phenotypic and agronomic attributes were recorded. This data matrix was analyzed by cluster, principal co-ordinates, discriminant and correlation analyses to examine line relationships based on plant attributes and their association with site characteristics of climate and soil. Among the wide polymorphism of attributes across the collection zone, there were a number of notable phenotypic associations. One of these, with large green leaves, minimally dentate leaf margins, and light purple petioles, was widely distributed. Three others, one with a distinctive magenta leaf mark, dark purple petioles, and an upright habit; one with those same attributes but with a prostrate habit; and one with grey-green leaves, high frost resistance, and the ability to stay green and to produce high pod yields, were associated with climatic and soil characteristics in the north, east, and south of the collection zone, respectively. Days to flowering were longer in lines from saline soils at lower altitude, and plant vigor was greatest in lines from more fertile soils with higher rainfall. A wide variation in time to flower of lines at all collection sites contributes to the adaptation of M. polymorpha in subtropical Queensland and potentially to its persistence with future climate change.

5. Semantic Typology and Efficient Communication

Abstract

Crosslinguistic research on domains including kinship, color, folk biology, number, and spatial relations has documented the different ways in which languages carve up the world into named categories. Although word meanings vary widely across languages, unrelated languages often have words with similar or identical meanings, and many logically possible meanings are never observed. We review research suggesting that this pattern of constrained variation is explained in part by the need for words to support efficient communication. This research includes several recent studies that have formalized efficient communication in computational terms and a larger set of studies, both classic and recent, that do not explicitly appeal to efficient communication but are nevertheless consistent with this notion. The efficient communication framework has implications for the relationship between language and culture and for theories of language change, and we draw out some of these connections.

6. Visual Perception Principles in Constellation Creation

Author

Abstract

Many cultures share common constellations and common narratives about the stars in the night sky. Previous research has shown that this overlap in asterisms, minimal star groupings inside constellations, is clearly present across 27 distinct culture groups and can be explained in part by properties of individual stars (brightness) and properties of pairs of stars (proximity) (Kemp, Hamacher, Little, & Cropper, 2022). The same work, however, found no evidence that properties of triples (angle) and quadruples (good continuation) predicted constellation formation. We developed a behavioral experiment to explore how individuals form constellations under conditions that reduce cultural learning. We found that participants independently selected and connected similar stars, and that their responses were predicted by two properties of triples (angle and even spacing) in addition to the properties of brightness and proximity supported by previous work. Our findings lend further evidence to the theory that commonality of constellations across cultures is not a result of shared human history but rather stems from shared human nature.

Abstract

Anecdotal evidence suggests that multilinguals' ability to learn languages increases the more languages they know; experimental evidence supports the idea that language learning promotes the development of metalinguistic awareness. The aim of this study was to investigate whether multilinguals' grammatical metalinguistic awareness is related to their attainment over and above their language experience. In order to do this, it was necessary to investigate empirically the hypotheses that attainment in another language is related to multilinguals' experience of learning languages and to their metalinguistic awareness, and that metalinguistic awareness is related to language learning experience. Thirty native English-speaking educated adult multilinguale were assessedo n their ability to learn the initial stageso f Basque under controlled conditions, their previous language learning experience, and their metalinguistic awareness (explaining native language grammaticality judgements, MLAT4, translation from Middle Egyptian, knowledge of Basque rules, implicit and explicit artificial grammar tests). The data were analysed using regression analyses in a within-participants design. The results show that the multilinguals were better at learning Basque (1) the more languages they could read and had, at least partly, studied, and (2) the more explicit grammatical metalinguistic awareness they had developed. Multilinguals' explicit metalinguistic awareness assisted language learning over and above language experience when the Basque rule knowledge test was included in the set of metalinguistic variables, but not when it was excluded. Multilinguals' language experience was related to their performance on the tests of explicit metalinguistic awareness, but not to the implicit test, nor to hypothesised overacceptance of ungrammatical items on the implicit and explicit artificial grammar tests. As a group, the multilinguals were better at the explicit than the implicit artificial grammar tests. In an exploratory factor analysis of the six metalinguistic tests two factors were found, interpreted as deductive and inductive grammar awareness, which appear to correspond to Carroll's (1993) `grammatical sensitivity', and `inductive language learning'. Performance on metalinguistic tests that assessed both inductive and deductive grammar awareness was related to language learning attainment. The results suggest that multilinguals' language learning ability may be related to their development of explicit grammatical metalinguistic awareness, in addition to the other abilities they gain through their experience of language learning. iii

Abstract

The principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favour of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria. A total of 236 panellists from 56 countries participated in 4 online surveys and 2 hybrid meetings. Response rates across the 4 survey rounds were 87%, 83%, 83%, and 78%, respectively. Seventy-four percent of respondents felt that the current nomenclature was sufficiently flawed to consider a name change. The terms “nonalcoholic” and “fatty” were felt to be stigmatising by 61% and 66% of respondents, respectively. Steatotic liver disease was chosen as an overarching term to encompass the various aetiologies of steatosis. The term steatohepatitis was felt to be an important pathophysiological concept that should be retained. The name chosen to replace NAFLD was metabolic dysfunction–associated steatotic liver disease (MASLD). There was consensus to change the definition to include the presence of at least 1 of 5 cardiometabolic risk factors. Those with no metabolic parameters and no known cause were deemed to have cryptogenic steatotic liver disease. A new category, outside pure metabolic dysfunction–associated steatotic liver disease, termed metabolic and alcohol related/associated liver disease (MetALD), was selected to describe those with metabolic dysfunction–associated steatotic liver disease, who consume greater amounts of alcohol per week (140–350 g/wk and 210–420 g/wk for females and males, respectively). The new nomenclature and diagnostic criteria are widely supported and non-stigmati

18. Simplification Is Not Dominant in the Evolution of Chinese Characters.

Abstract

Linguistic systems are hypothesised to be shaped by pressures towards communicative efficiency that drive processes of simplification. A longstanding illustration of this idea is the claim that Chinese characters have progressively simplified over time. Here we test this claim by analyzing a dataset with more than half a million images of Chinese characters spanning more than 3,000 years of recorded history. We find no consistent evidence of simplification through time, and contrary to popular belief we find that modern Chinese characters are higher in visual complexity than their earliest known counterparts. One plausible explanation for our findings is that simplicity trades off with distinctiveness, and that characters have become less simple because of pressures towards distinctiveness. Our findings are therefore compatible with functional accounts of language but highlight the diverse and sometimes counterintuitive ways in which linguistic systems are shaped by pressures for communicative efficiency.

19. Perceptual Grouping Explains Similarities in Constellations Across Cultures

Author

Kemp, C, Hamacher, DW, Little, DR, Cropper, SJ, Kemp, C, Hamacher, DW, Little, DR, and Cropper, SJ

Abstract

Cultures around the world organize stars into constellations, or asterisms, and these groupings are often considered to be arbitrary and culture specific. Yet there are striking similarities in asterisms across cultures, and groupings such as Orion, the Big Dipper, the Pleiades, and the Southern Cross are widely recognized across many different cultures. Psychologists have informally suggested that these shared patterns are explained by Gestalt laws of grouping, but there have been no systematic attempts to catalog asterisms that recur across cultures or to explain the perceptual basis of these groupings. Here, we compiled data from 27 cultures around the world and found that a simple computational model of perceptual grouping accounts for many of the recurring cross-cultural asterisms. Our results suggest that basic perceptual principles account for more of the structure of asterisms across cultures than previously acknowledged and highlight ways in which specific cultures depart from this shared baseline.

Abstract

OBJECTIVES: Providers who work closely with ethnic minority people with dementia and their families are pivotal in helping them access services. However, few studies have examined how these providers actually do this work. Using the concept of "boundary crossers," this article investigates the strategies applied by these providers to facilitate access to dementia services for ethnic minority people with dementia and their families. METHODS: Between 2017 and 2020, in-depth video-recorded interviews were conducted with 27 health, aged care, and community service providers working with ethnic minority people living with dementia across Australia. Interviews were conducted in one of seven languages and/or in English, then translated and transcribed verbatim into English. The data were analyzed thematically. RESULTS: Family and community stigma associated with dementia and extra-familial care were significant barriers to families engaging with services. To overcome these barriers, participants worked at the boundaries of culture and dementia, community and systems, strategically using English and other vernaculars, clinical and cultural terminology, building trust and rapport, and assisting with service navigation to improve access. Concurrently, they were cognizant of familial boundaries and were careful to provide services that were culturally appropriate without supplanting the families' role. DISCUSSION: In negotiating cultural, social, and professional boundaries, providers undertake multidimensional and complex work that involves education, advocacy, negotiation, navigation, creativity, and emotional engagement. This work is largely undervalued but offers a model of care that facilitates social and community development as well as service integration across health, aged care, and social services.

Abstract

PR, IFPRI3; ISI; DCA; CRP4; 2 Promoting Healthy Diets and Nutrition for all, PHND; A4NH, CGIAR Research Program on Agriculture for Nutrition and Health (A4NH), Malnutrition is a leading cause of death and disability among children in low-income countries. Nutrition-sensitive interventions show promise in increasing food access and improving diets. There are possible synergies of integrating these programs with other sectors, improving effectiveness by leveraging resources. However, economic evaluations of these multi-sectoral programs are limited. We aimed to estimate the cost efficiency, cost-effectiveness, benefit-cost ratio, and net benefit of using community-based early childhood development (ECD) centers as platforms for an intervention promoting agricultural production and nutrition among households with young children in Malawi. The intervention was costed using bottom-up micro-costing and top-down expenditure analysis with a societal perspective and a 12-month horizon. Effectiveness estimates were derived from a cluster-randomized control trial. Premature deaths and stunting cases averted were estimated using the Lived Saved Tool. We calculated DALYs averted, and the value of three benefits streams resulting from reductions in premature mortality, increases in lifetime productivity and household agricultural productivity. We transferred the US value of a statistical life (VSL) to Malawi using an income elasticity of 1.5, and a 10% discount rate. Probabilistic sensitivity analysis was conducted using a Monte Carlo model. The intervention cost $197,377, reaching 4,806 beneficiaries at $41 per beneficiary, $595 per case of stunting, $18,310 per death, and $516 per DALY averted. Net benefit estimates ranged from $507,589 to $4,678,258, and benefit-cost ratios from 3.57 to 24.70. Sensitivity analyses confirmed a positive return on investment. Implementing agriculture-nutrition interventions through ECD platforms may be an efficient use of resources in Malawi and similar contexts.
