Doing referring in Murriny Patha conversation

Successful communication hinges on keeping track of who and what we are talking about. For this reason, person reference sits at the heart of the social sciences. Referring to persons is an interactional process where information is transferred from current speakers to the recipients of their talk. This dissertation concerns itself with the work that is achieved through this transfer of information. The interactional approach adopted is one that combines the “micro” of conversation analysis with the “macro” of genealogically grounded anthropological linguistics. Murriny Patha, a non-Pama-Nyungan language spoken in the north of Australia, is a highly complex polysynthetic language with kinship categories that are grammaticalized as verbal inflections. For referring to persons, as well as names, nicknames, kinterms, minimal descriptions and free pronouns, Murriny Patha speakers make extensive use of pronominal reference markers embedded within polysynthetic verbs. Murriny Patha does not have a formal “mother-in-law” register. There are however numerous taboos on naming kin in avoidance relationships, and on naming and their namesakes. Similarly, there are also taboos on naming the deceased and on naming their namesakes. As a result, for every speaker there is a multitude of people whose names should be avoided. At any one time, speakers of the language have a range of referential options. Speakers’ decisions about which category of reference forms to choose (names, kinterms etc.) are governed by conversational preferences that shape “referential design”. Six preferences – a preference for associating the referent to the co-present conversationalists, a preference for avoiding personal names, a preference for using recognitionals, a preference for being succinct, and a pair of opposed preferences relating to referential specificity – guide speakers towards choosing a name on one occasion, a kinterm on the next occasion and verbal cross-reference on yet another occasion. Different classes of expressions better satisfy particular conversational preferences. There is a systematicity to the referential choices that speakers make. The interactional objectives of interlocutors are enacted through the regular placement of particular forms in particular sequential environments. These objectives are then revealed through the turn-by-turn unfolding of conversational interaction

Classroom-evaluated school performance at nine years of age after very preterm birth

Objective: To determine classroom-evaluated school performance nine years after preterm birth, predicted by perinatal risk factors and neonatal brain abnormalities.Study design: Children were recruited from a consecutive cohort of 113 preterm infants (<32 weeks’ gestation), participating in a longitudinal prospective study, investigating brain injury and neurodevelopmental outcome. Data on perinatal risk factors, presence of brain injury at term-equivalent age, and maternal education were collected. Information on school performance included enrollment in special (primary) education, grade repetition and school results from the nationwide standardized Dutch Pupil Monitoring System regarding reading comprehension, spelling, and mathematics.Results: Information on school enrollment was available for 87 children (77%), of whom 7 (8%) were in special primary education and 19 (22%) repeated a grade. This was significantly higher compared to national rates (p ≤ .05). Results on school performance were available for 74 children (65%) and showed clearly below average scores in reading comprehension (p = .006), spelling (p = .014) and mathematics (p <.001). Univariate analysis showed that lower performance in reading comprehension was predicted by male sex and low maternal education; spelling by male sex; and mathematics by BPD, white matter injury and maternal education. In a multivariate model, male sex and maternal education were predictive for reading comprehension and white matter injury for mathematics. Conclusion: Preterm born children more often need special primary education and have higher grade repeat rates. They perform poorer on reading comprehension, spelling and mathematics. Regular follow-up remains important for preterm born children during school age. New methods for child psychiatric diagnosis and treatment outcome evaluatio

‘You feel like you haven’t got any control’: A qualitative study of side effects from medicines

Objectives: An aging UK population and multi-morbidity means patients are receiving an increasing number of medicines. This can lead to greater risk of unintended side effects. The aim of this study was to increase understanding of how people identify and manage side effects from their medicines. Design: A qualitative interview study with patients who had experienced side effects, recruited from community pharmacies. Methods: This study examined patients’ experiences of side effects and the impact of these effects on their daily life. Fifteen participants were interviewed – 10 females and 5 males, with ages that ranged between 25 and 80 years, using different types and numbers of medicines. Results: Thematic analysis revealed six themes: side effect experience, identification, adherence, information use, coping and body awareness. Participants described a wide range of physical and psychological symptoms which had both explicit and implicit impact on their lives. A system of identification based on constructed cognitive processes was common across participants. A variety of strategies were used by participants to cope with their side effects which included information seeking, social support seeking and non-adherent behaviours. Conclusions: Psychological factors, such as medication beliefs, symptom interpretation and body awareness, contribute to cognitive and behavioural processes used to identify and manage side effects. These processes can have significant impacts on an individual’s decisions about adherence

Adjuvant capecitabine-containing chemotherapy benefit and homologous recombination deficiency in early-stage triple-negative breast cancer patients

Background The addition of adjuvant capecitabine to standard chemotherapy of early-stage triple-negative breast cancer (TNBC) patients has improved survival in a few randomised trials and in meta-analyses. However, many patients did not benefit. We evaluated the BRCA1-like DNA copy number signature, indicative of homologous recombination deficiency, as a predictive biomarker for capecitabine benefit in the TNBC subgroup of the FinXX trial. Methods Early-stage TNBC patients were randomised between adjuvant capecitabine-containing (TX + CEX: capecitabine-docetaxel, followed by cyclophosphamide-epirubicin-capecitabine) and conventional chemotherapy (T + CEF: docetaxel, followed by cyclophosphamide-epirubicin-fluorouracil). Tumour BRCA1-like status was determined on low-coverage, whole genome next-generation sequencing data using an established DNA comparative genomic hybridisation algorithm. Results For 129/202 (63.9%) patients the BRCA1-like status could be determined, mostly due to lack of tissue. During a median follow-up of 10.7 years, 35 recurrences and 32 deaths occurred. Addition of capecitabine appears to improve recurrence-free survival more among 61 (47.3%) patients with non-BRCA1-like tumours (HR 0.23, 95% CI 0.08-0.70) compared to 68 (52.7%) patients with BRCA1-like tumours (HR 0.66, 95% CI 0.24-1.81) (P-interaction = 0.17). Conclusion Based on our data, patients with non-BRCA1-like TNBC appear to benefit from the addition of capecitabine to adjuvant chemotherapy. Patients with BRCA1-like TNBC may also benefit. Additional research is needed to define the subgroup within BRCA1-like TNBC patients who may not benefit from adjuvant capecitabine.Peer reviewe

National records of 3000 European bee and hoverfly species: A contribution to pollinator conservation

Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge of their distribution at the national and continental levels is needed to implement efficient conservation actions, but this knowledge is still fragmented and/or difficult to access. As a step forward, we provide an updated list of around 3000 European bee and hoverfly species, reflecting their current distributional status at the national level (in the form of present, absent, regionally extinct, possibly extinct or non-native). This work was attainable by incorporating both published and unpublished data, as well as knowledge from a large set of taxonomists and ecologists in both groups. After providing the first National species lists for bees and hoverflies for many countries, we examine the current distributional patterns of these species and designate the countries with highest levels of species richness. We also show that many species are recorded in a single European country, highlighting the importance of articulating European and national conservation strategies. Finally, we discuss how the data provided here can be combined with future trait and Red List data to implement research that will further advance pollinator conservation

Tractography of developing white matter of the internal capsule and corpus callosum in very preterm infants

To investigate in preterm infants associations between Diffusion Tensor Imaging (DTI) parameters of the posterior limb of the internal capsule (PLIC) and corpus callosum (CC) and age, white matter (WM) injury and clinical factors. In 84 preterm infants DTI was performed between 40-62 weeks postmenstrual age on 3 T MR. Fractional anisotropy (FA), apparent diffusion coefficient (ADC) values and fibre lengths through the PLIC and the genu and splenium were determined. WM injury was categorised as normal/mildly, moderately and severely abnormal. Associations between DTI parameters and age, WM injury and clinical factors were analysed. A positive association existed between FA and age at imaging for fibres through the PLIC (r = 0.48 p < 0.001) and splenium (r = 0.24 p < 0.01). A negative association existed between ADC and age at imaging for fibres through the PLIC (r = -0.65 p < 0.001), splenium (r = -0.35 p < 0.001) and genu (r = -0.53 p < 0.001). No association was found between DTI parameters and gestational age, degree of WM injury or categorical clinical factors. These results indicate that in our cohort of very preterm infants, at this young age, the development of the PLIC and CC is ongoing and independent of the degree of prematurity or WM injury.Neuro Imaging Researc

Demand and experiences with financial products and services in climate smart villages

This study ‘Demand for and experiences with financial products and services’ describes and discusses the results of a survey to provide a first insight into the financial services that the smallholder farmers from climate smart villages use and to explore how these are related to climate smart agricultural technologies & practices. The study is one of three preliminary studies of a multi-year international research project (2016-2022) on ‘Business models, incentives and innovative finance for scaling climate smart agriculture (CSA)’. The knowledge and insights developed are used to further support ongoing and emerging climate smart projects in which CCAFS is involved. A survey was conducted to identify smallholder farmers and the small to medium enterprises (in different stages of the value chain) and their demand for and experiences with financial products and services. There were 148 respondents from 24 villages from Latin America, West Africa, East Africa, Southeast Asia and South Asia. The targeted number of female respondents (50%) was nog met in all regions, for example in India where the role of female farmers in irrigated agriculture would be limited. A limitation to the results is that in different regions a different number of villages was involved, making it more difficult to generalise results. Sometimes it would prove challenging to make conclusions about the reasoning behind the answers. The study is about adoption climate smart agriculture, but does not define the extent of adoption. .

The Effects of Aphid Traits on Parasitoid Host Use and Specialist Advantage

Specialization is a central concept in ecology and one of the fundamental properties of parasitoids. Highly specialized parasitoids tend to be more efficient in host-use compared to generalized parasitoids, presumably owing to the trade-off between host range and hostuse efficiency. However, it remains unknown how parasitoid host specificity and host-use depends on host traits related to susceptibility to parasitoid attack. To address this question, we used data from a 13-year survey of interactions among 142 aphid and 75 parasitoid species in nine European countries. We found that only aphid traits related to local resource characteristics seem to influence the trade-off between host-range and efficiency: more specialized parasitoids had an apparent advantage (higher abundance on shared hosts) on aphids with sparse colonies, ant-attendance and without concealment, and this was more evident when host relatedness was included in calculation of parasitoid specificity. More traits influenced average assemblage specialization, which was highest in aphids that are monophagous, monoecious, large, highly mobile (easily drop from a plant), without myrmecophily, habitat specialists, inhabit non-agricultural habitats and have sparse colonies. Differences in aphid wax production did not influence parasitoid host specificity and host-use. Our study is the first step in identifying host traits important for aphid parasitoid host specificity and host-use and improves our understanding of bottom-up effects of aphid traits on aphid-parasitoid food web structure
