When Did I Know Thee? Let Me Count the Months: Retrospective Accounts of Impression Formation in Close Relationships
The current study utilizes relationship models and theories to file down how, why, and when people develop evaluations of others at zero acquaintance. A key aspect of the study is determining the relationship between Big Five traits and judgment accuracy, as well as how it fared over time (2 months). We took a sample of two-hundred and six participants and had them rate a target with closed and open-ended questions and rating scales. We found that Extraversion was the most salient and most accurately judged at zero acquaintance. Further, Neuroticism was noted most often in open-ended questions and only became detectable after several weeks. Conscientiousness and Openness were also not detected until several weeks had passed. Most notably, Agreeableness proved to have very early detection and judgement accuracy which remained the most stable over time
Incidence, risk factors and the healthcare cost of falls postdischarge after elective total hip and total knee replacement surgery: protocol for a prospective observational cohort study
Abstract:
Introduction:
The number of major joint replacement procedures continues to increase in Australia. The primary aim of this study is to determine the incidence of falls in the first 12 months after discharge from hospital in a cohort of older patients who undergo elective total hip or total knee replacement.
Methods and analyses:
A prospective longitudinal observational cohort study starting in July 2015, enrolling patients aged â„60 years who are admitted for elective major joint replacement (n=267 total hip replacement, n=267 total knee replacement) and are to be discharged to the community. Participants are followed up for 12 months after hospital discharge. The primary outcome measure is the rate of falls per thousand patient-days. Falls data will be collected by 2 methods: issuing a falls diary to each participant and telephoning participants monthly after discharge. Secondary outcomes include the rate of injurious falls and health-related quality of life. Patient-rated outcomes will be measured using the Oxford Hip or Oxford Knee score. Generalised linear mixed modelling will be used to examine the falls outcomes in the 12 months after discharge and to examine patient and clinical characteristics predictive of falls. An economic evaluation will be conducted to describe the nature of healthcare costs in the first 12 months after elective joint replacement and estimate costs directly attributable to fall events.
Ethics and dissemination:
The results will be disseminated through local site networks and will inform future services to support older people undergoing hip or knee joint replacement and also through peer-reviewed publications and medical conferences. This study has been approved by The University of Notre Dame Australia and local hospital human research ethics committees. Trial registratio

An Investigation of the Effect of Graphite Degradation on the Irreversible Capacity in Lithium-ion Cells
The effect of surface structural damage on graphitic anodes, commonly observed in tested Li-ion cells, was investigated. Similar surface structural disorder was artificially induced in Mag-10 synthetic graphite anodes using argon-ion sputtering. Raman microscopy, scanning electron microscopy (SEM) and Brunauer Emmett Teller (BET) measurements confirmed that Ar-ion sputtered Mag-10 electrodes display similar degree of surface degradation as the anodes from tested Li-ion cells. Artificially modified Mag-10 anodes showed double the irreversible charge capacity during the first formation cycle, compared to fresh un-altered anodes. Impedance spectroscopy and Fourier transform infrared (FTIR) spectroscopy on surface modified graphite anodes indicated the formation of a thicker and slightly more resistive SEI layer. Gas chromatography/mass spectroscopy (GC/MS) analysis of solvent extracts from the electrodes detected the presence of new compounds with M{sub w} on the order of 1600 g mol{sup -1} for the surface modified electrode with no evidence of elevated M{sub w} species for the unmodified electrode. The structural disorder induced in the graphite during long-term cycling maybe responsible for the slow and continuous SEI layer reformation, and consequently, the loss of reversible capacity due to the shift of lithium inventory in cycled Li-ion cells
Wounds on Rapanea melanophloeos provide habitat for a large diversity of Ophiostomatales including four new species
Rapanea melanophloeos, an important canopy tree in Afromontane forests,
is commonly utilised for medicinal bark harvesting. Wounds created from these
activities provide entrance for many fungi, including arthropod-associated members
of the Ophiostomatales and Microascales (ophiostomatoid fungi). In this study we
assess the diversity of wound-associated Ophiostomatales on storm-damaged R.
melanophloeos trees in the Afromontane forests of South Africa. Five species were identified based on micro-morphological and molecular phylogenetic analyses. These
included Ophiostoma stenoceras and four newly described taxa Sporothrix itsvoense
sp. nov., S. rapaneae sp. nov., S. utae sp. nov. and O. noisomeae sp. nov. Four of
these are members of the S. schenckii-O. stenoceras complex (O. stenoceras, S.
itsvoense sp. nov., S. rapaneae sp. nov., S. utae) while O. noisomeae groups basal in
the Ophiostomatales alongside the S. lignivora complex and Graphilbum. In addition
to other taxa known from this host, the present study shows that there is a rich, yet
still poorly explored, diversity of Ophiostomatales associated with R. melanophloeos
in Afromontane forests. More taxa are likely to be discovered with increased research
effort. These must be assessed in terms of pathogenicity towards this ecologically and
economically important tree.http://link.springer.com/journal/104822017-06-30hb2016GeneticsMicrobiology and Plant Patholog
New species of Ophiostomatales from Scolytinae and Platypodinae beetles in the Cape Floristic Region, including the discovery of the sexual state of Raffaelea
Olea capensis and Rapanea melanophloeos
are important canopy trees in South African
Afromontane forests. Dying or recently dead individuals
of these trees are often infested by Scolytinae and
Platypodinae (Curculionidae) beetles. Fungi were
isolated from the surfaces of beetles emerging from
wood samples and their galleries. Based on micromorphological
and phylogenetic analyses, four fungal
species in the Ophiostomatales were isolated. These were Sporothrix pallida and three taxa here newly
described as Sporothrix aemulophila sp. nov., Raffaelea
vaginata sp. nov. and Raffaelea rapaneae sp. nov.
This study represents the first collection of S. pallida, a
species known from many environmental samples
from across the world, from Scolytinae beetles. S.
aemulophila sp. nov. is an associate of the ambrosia
beetle Xyleborinus aemulus. R. rapaneae sp. nov. and
R. vaginata sp. nov. were associated with a Lanurgus
sp. and Platypodinae beetle, respectively, and represent
the first Raffaelea spp. reported from the Cape
Floristic Region. Of significance is that R. vaginata
produced a sexual state analogous with those of Ophiostoma seticolle and O. deltoideosporum that
also grouped in our analyses in Raffaelea s. str., to date
considered an asexual genus. The morphology of the
ossiform ascospores and anamorphs of the three
species corresponded and the generic circumscription
of Raffaelea is thus emended to accommodate sexual
states. The two known species are provided with new
combinations, namely Raffaelea seticollis (R.W.
Davidson) Z.W. de Beer and T.A. Duong comb. nov.
and Raffaelea deltoideospora (Olchow. and J. Reid)

The Eurasian Modern Pollen Database (EMPD), version 2
The Eurasian (nĂ©e European) Modern Pollen Database (EMPD) was established in 2013 to provide a public database of high-quality modern pollen surface samples to help support studies of past climate, land cover, and land use using fossil pollen. The EMPD is part of, and complementary to, the European Pollen Database (EPD) which contains data on fossil pollen found in Late Quaternary sedimentary archives throughout the Eurasian region. The EPD is in turn part of the rapidly growing Neotoma database, which is now the primary home for global palaeoecological data. This paper describes version 2 of the EMPD in which the number of samples held in the database has been increased by 60â% from 4826 to 8134. Much of the improvement in data coverage has come from northern Asia, and the database has consequently been renamed the Eurasian Modern Pollen Database to reflect this geographical enlargement. The EMPD can be viewed online using a dedicated map-based viewer at https://empd2.github.io and downloaded in a variety of file formats at https://doi.pangaea.de/10.1594/PANGAEA.909130 (Chevalier et al., 2019)Swiss National Science Foundation | Ref. 200021_16959

Childrenâs and adolescentsâ rising animal-source food intakes in 1990â2018 were impacted by age, region, parental education and urbanicity
Animal-source foods (ASF) provide nutrition for children and adolescentsâ physical and cognitive development. Here, we use data from the Global Dietary Database and Bayesian hierarchical models to quantify global, regional and national ASF intakes between 1990 and 2018 by age group across 185 countries, representing 93% of the worldâs child population. Mean ASF intake was 1.9 servings per day, representing 16% of children consuming at least three daily servings. Intake was similar between boys and girls, but higher among urban children with educated parents. Consumption varied by age from 0.6 at <1 year to 2.5 servings per day at 15â19 years. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week, with increases in all regions except sub-Saharan Africa. In 2018, total ASF consumption was highest in Russia, Brazil, Mexico and Turkey, and lowest in Uganda, India, Kenya and Bangladesh. These findings can inform policy to address malnutrition through targeted ASF consumption programmes.publishedVersio
Incident type 2 diabetes attributable to suboptimal diet in 184 countries
The global burden of diet-attributable type 2 diabetes (T2D) is not well established. This risk assessment model estimated T2D incidence among adults attributable to direct and body weight-mediated effects of 11 dietary factors in 184 countries in 1990 and 2018. In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.8â14.4 million) incident T2D cases, representing 70.3% (68.8â71.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.0â27.1%)), excess refined rice and wheat intake (24.6% (22.3â27.2%)) and excess processed meat intake (20.3% (18.3â23.5%)). Across regions, highest proportional burdens were in central and eastern Europe and central Asia (85.6% (83.4â87.7%)) and Latin America and the Caribbean (81.8% (80.1â83.4%)); and lowest proportional burdens were in South Asia (55.4% (52.1â60.7%)). Proportions of diet-attributable T2D were generally larger in men than in women and were inversely correlated with age. Diet-attributable T2D was generally larger among urban versus rural residents and higher versus lower educated individuals, except in high-income countries, central and eastern Europe and central Asia, where burdens were larger in rural residents and in lower educated individuals. Compared with 1990, global diet-attributable T2D increased by 2.6 absolute percentage points (8.6 million more cases) in 2018, with variation in these trends by world region and dietary factor. These findings inform nutritional priorities and clinical and public health planning to improve dietary quality and reduce T2D globally.publishedVersio
