- Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions. We addressed this question by replicating Oosterhof and Todorov's methodology across 11 world regions, 41 countries and 11,570 participants. When we used Oosterhof and Todorov's original analysis strategy, the valence-dominance model generalized across regions. When we used an alternative methodology to allow for correlated dimensions, we observed much less generalization. Collectively, these results suggest that, while the valence-dominance model generalizes very well across regions when dimensions are forced to be orthogonal, regional differences are revealed when we use different extraction methods and correlate and rotate the dimension reduction solution.

European soil seed bank communities across a climate and land-cover gradient
- 2020
-
Annan publikationabstract
- This is the data set used for the publication Buffering effects of soil seed banks on plant community composition in response to land use and climate, published in the journal Global Ecology and Biogeography.Aim.Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help plant communities to resist or at least postpone the detrimental impact of global changes. This study investigates the potential for soil seed banks to achieve this.Location. EuropeTime period. 1978 – 2014Major taxa studied. Flowering plantsMethods.Using a space-for-time/warming approach, we study plant species richness and composition in the herb layer and the soil seed bank in 2796 community plots from 54 datasets in managed grasslands, forests and intermediate, successional habitats across a climate gradient.Results.Soil seed banks held more species than the herb layer, being compositionally similar across habitats. Species richness was lower in forests and successional habitats compared to grasslands, with annual temperature range more important than mean annual temperature for determining richness. Climate and land use effects were generally less pronounced when plant community richness included seed bank species richness, while there was no clear effect of land use and climate on compositional similarity between the seed bank and the herb layer.Main conclusions.High seed bank diversity and compositional similarity between the herb layer and seed bank plant communities may provide a potentially important functional buffer against the impact of ongoing environmental changes on plant communities. This capacity could, however, be threatened by climate warming. Dormant life-history stages can therefore be important sources of diversity in changing environments, potentially underpinning already observed time-lags in plant community responses to global change. However, as soil seed banks themselves appear, albeit less, vulnerable to the same changes, their potential to buffer change can only be temporary, and major community shifts may still be expected.MethodsThis dataset is a collection of 41 published and 5 unpublished data sets, consisting of 2796 plots with corresponding seed bank and herb layer community data. Sampling effort varied across data sets, but involved sampling of the soil and subsequent germination trials in a greenhouse to determine seed bank composition. Herb layer communities were determined by the identification of plants in relevés. Please consult the readme file and published paper for further details.Usage NotesPlease contact database or individual data set authors for further information and collaboration when using the data set or any of its component parts. Please also note that some of these data sets have already been published alongside their orginal papers. Finally, please cite data and datasets according to community standards.

Removal of heavy metals in potw using alum or sodium aluminate for phosphorus removal
- 1984
-
Ingår i: Proceedings of Mid-Atlantic Industrial Waste Conference. ; , s. 318-330
-
Konferensbidrag (refereegranskat)abstract
- The addition of alum or sodium aluminate at dosages which effectively remove phosphorus is beneficial in removing copper, chromium, and lead when present in wastewaters. Chromium removal is enhanced by sodium aluminate addition, but alum does not affect chromium removal. Both types of aluminum salts appear to increase the removal of lead, but the large variance in the data does not allow this to be confirmed by the t-tests. Of the remaining metals analyzed, no difference in removal was observed with and without aluminum salt addition for cadmium or antimony, nor was there any difference in TOC removal. Mercury was effectively removed to below the detection limit by primary sedimentation, so no further removal was achieved during secondary treatment when the alum/aluminate was added. Other metals were not present in amounts above detection limits.

Removal of Heavy Metals in Publicly Owned Treatment Works
- 1987
-
Ingår i: Environmental Progress. ; 6:2, s. 91-98
-
Tidskriftsartikel (refereegranskat)abstract
- Studies were conducted at three activated sludge treatment plants during normal operation. The heavy metals were measured in the influent to each plant, the primary sedimentation effluent where applicable, the discharge after activated sludge treatment and secondary sedimentation, and in one case after a final polishing filter. Both the soluble and the total portions were measured. Beryllium, nickel, and thallium were not found in detectable levels in any of the plant influents. Mercury was found in only trace amounts. The removals of the other metals varied considerably. No consistent conclusions can be made from the data; each metal, soluble or total fraction, and unit treatment operation must be interpreted individually. The only metal in the plant effluents consistently above the recommended limit was arsenic, and this barely above the limit, and the lead content from Fitchburg, despite 83% removal.

Childbirth and parenting preparation in antenatal classes
- 2018
-
Ingår i: Midwifery. - : Elsevier BV. - 0266-6138 .- 1532-3099. ; 57, s. 1-7

Tidskriftsartikel (refereegranskat)abstract
- Objectives: to describe topics (1) presented by midwives' during antenatal classes and the amount of time spent on these topics and (2) raised and discussed by first-time parents and the amount of time spent on these topics. Design: qualitative; data were gathered using video or tape recordings and analysed using a three-pronged content analysis approach, i.e., conventional, summative, and directed analyses. Setting and participants: 3 antenatal courses in 2 antenatal units in a large Swedish city; 3 midwives; and 34 course participants. Findings: class content focused on childbirth preparation (67% of the entire antenatal course) and on parenting preparation (33%). Childbirth preparation facilitated parents' understanding of the childbirth process, birthing milieu, the partner's role, what could go wrong during delivery, and pain relief advantages and disadvantages. Parenting preparation enabled parents to (i) plan for those first moments with the newborn; (ii) care for/physically handle the infant; (iii) manage breastfeeding; (iv) manage the period at home immediately after childbirth; and (v) maintain their relationship. During the classes, parents expressed concerns about what could happened to newborns. Parents' questions to midwives and discussion topics among parents were evenly distributed between childbirth preparation (52%) and parenting preparation (48%). Key conclusions: childbirth preparation and pain relief consumed 67% of course time. Parents particularly reflected on child issues, relationship, sex, and anxiety. Female and male participants actively listened to the midwives, appeared receptive to complex issues, and needed more time to ask questions. Parents appreciated the classes yet needed to more information for managing various post-childbirth situations. Implications for practice: while midwifery services vary among hospitals, regions, and countries, midwives might equalise content focus, offer classes in the second trimester, provide more time for parents to talk to each other, allow time in the course plan for parents to bring up new topics, and investigate: (i) ways in which antenatal course development and planning can improve; (ii) measures for evaluating courses; (iii) facilitator training; and (iv) parent satisfaction surveys.
