Published: September 2019

Abstract
The biannual seasonal rainfall regime over the southern part of West Africa is characterised by two wet seasons, separated by the ‘Little Dry Season’ in July–August. Lower rainfall totals during this intervening dry season may be detrimental for crop yields over a region with a dense population that depends on agricultural output. Coupled Model Intercomparison Project Phase 5 (CMIP5) models do not correctly capture this seasonal regime, and instead generate a single wet season, peaking at the observed timing of the Little Dry Season. Hence, the realism of future climate projections over this region is questionable. Here, the representation of the Little Dry Season in coupled model simulations is investigated, to elucidate factors leading to this misrepresentation. The Global Ocean Mixed Layer configuration of the Met Office Unified Model is particularly useful for exploring this misrepresentation, as it enables separating the effects of coupled model ocean biases in different ocean basins while maintaining air–sea coupling. Atlantic Ocean SST biases cause the incorrect seasonal regime over southern West Africa. Upper level descent in August reduces ascent along the coastline, which is associated with the observed reduction in rainfall during the Little Dry Season. When coupled model Atlantic Ocean biases are introduced, ascent over the coastline is deeper and rainfall totals are higher during July–August. Hence, this study indicates detrimental impacts introduced by Atlantic Ocean biases, and highlights an area of model development required for production of meaningful climate change projections over the West Africa region.
Fungi in the Canopy: How Soil Fungi and Extracellular Enzymes Differ Between Canopy and Ground Soils
Authors: Looby Caitlin I. , Hollenbeck Emily C. , Treseder Kathleen K. 
Published: September 2019

AbstractTropical montane cloud forests contain a large abundance and diversity of canopy epiphytes, which depend on canopy soil to retain water and nutrients. We lack an in depth understanding of how these soils contribute to ecosystem processes and soil diversity and how sensitive they may be to projected climate change. We compared canopy and ground soils in Monteverde, Costa Rica, to determine how these two soil types differ in their extracellular enzyme activity (EEA) and fungal communities. Samples were also collected along two elevation gradients to reveal if canopy soils differed in how EEA and fungal communities responded to elevation compared to ground soils. We found that canopy soils had higher EEA than ground soils. Fungal communities were less diverse and differed significantly between the two soil types. These differences were associated with higher relative abundances of yeasts and endophytes in canopy soils. The relative abundances of free-living filamentous fungi and yeasts shifted more dramatically with elevation in canopy soils compared to ground soils. Our study suggests that canopy soils may be a reservoir for endophytes. Epiphytes may invest in symbionts that promote stress tolerance over mycorrhizal fungi whose high resource demands are costly and less beneficial. Overall, soils harbor distinct fungal communities that may be altered under projected climate change.
Global budget versus cost ceiling: a natural experiment in hospital payment reform in the Netherlands
Authors: Gaspar Katalin , Portrait France , van der Hijden Eric , Koolman Xander 
Published: September 2019

Abstract
Global budget (GB) arrangements have become a popular method worldwide to control the rise in healthcare expenditures. By guaranteeing hospital funding, payers hope to eliminate the drive for increased production, and incentivize providers to deliver more efficient care and lower utilization. We evaluated the introduction of GB contracts by certain large insurers in Dutch hospital care in 2012 and compared health care utilization to those insurers who continued with more traditional production-based contracts, i.e., cost ceiling (CC) contracts. We used the share of GB hospital funding per postal code region to study the effect of contract types. Our findings show that having higher share of GB financing was associated with lower growth in treatment intensity, but it was also associated with higher growth in the probability of having at least one hospital visit. While the former finding is in line with our expectation, the latter is not and suggests that hospital visits may take longer to respond to contract incentives. Our study covers the years of 2010–2013 (2 years before and 2 years following the introduction of the new contracts). Therefore, our results capture only short-term effects.
Corporate religiosity and individual decision on conducting entrepreneurial activity: The contingent effects of institutional environments in China
Authors: Zhang Feng , Zhang Haina , Bell Geoffrey G. 
Published: September 2019

AbstractThis study draws on the institutional void and institutional support perspectives to examine the contingent effect of institutional environments on the relationship between corporate religiosity and individual entrepreneurial activity in the context of emerging markets. We employ a composite dataset that covers 7109 individuals in 69 major cities across 25 provinces in China. Our study provides convincing evidence that individuals with strong corporate religiosity may be disinclined to conduct entrepreneurial activity in corrupted markets, but are more likely to engage in entrepreneurship in well-developed markets (ones characterized by high levels of marketization). This study displays the interplay of both institutional void and institutional support with corporate religiosity in shaping individual behaviors.
Using Sexual Selection Theories to Examine Contextual Variation in Heterosexual Women’s Orientation Toward High Heels
Authors: Watkins Christopher , Leitch Amanda 
Published: September 2019

Abstract
High heels are symbols of female sexuality and are “costly signals” if the risks of wearing them are offset by improving women’s attractiveness to men. From a functionalist perspective, the costs versus benefits of wearing heels may vary according to personal and contextual factors, such as her effectiveness at competing for mates, or at times when such motives are stronger. Here, we examined potential differences between women (self-rated attractiveness, dyadic versus solitary sexual desire, women’s age, competitive attitudes toward other women) and contextual variation (priming mating and competitive motives) in their responses to high heels. Study 1 (N = 79) and Study 2 (N = 273) revealed that self-rated attractiveness was positively related to orientation toward heeled shoes. When examining responses to two very attractive shoes (one higher heel, one lower heel) in Study 2, dyadic sexual desire, but not solitary sexual desire or intrasexual competitiveness, predicted their inclination to buy the higher-heeled shoe. In Study 3 (N = 142), young women chose high heels when primed with free choice of a designer shoe (95% CI [53.02 mm, 67.37 mm]) and preferred a heel 22 mm (0.87”) higher than older women (Study 4, N = 247). Contrary to predictions, priming mating or competitive motives did not alter women’s preference toward a higher heel (Studies 3 and 4). Our studies suggest that attractive women augment their physical appeal via heels. High heels may be a subtle indicator of dyadic sexual desire, and preferences for heels are stronger at times in the lifespan when mating competition is relatively intense.
Explicating Objectual Understanding: Taking Degrees Seriously
Authors: Baumberger Christoph 
Published: September 2019

AbstractThe paper argues that an account of understanding should take the form of a Carnapian explication and acknowledge that understanding comes in degrees. An explication of objectual understanding is defended, which helps to make sense of the cognitive achievements and goals of science. The explication combines a necessary condition with three evaluative dimensions: an epistemic agent understands a subject matter by means of a theory only if the agent commits herself sufficiently to the theory of the subject matter, and to the degree that the agent grasps the theory (i.e., is able to make use of it), the theory answers to the facts and the agent’s commitment to the theory is justified. The threshold for outright attributions of understanding is determined contextually. The explication has descriptive as well as normative facets and allows for the possibility of understanding by means of non-explanatory (e.g., purely classificatory) theories.
The Milk Protein Alpha-Casein Suppresses Triple Negative Breast Cancer Stem Cell Activity Via STAT and HIF-1alpha Signalling Pathways in Breast Cancer Cells and Fibroblasts

Abstract
Triple negative breast cancer (TNBC) is the most lethal breast cancer subtype. Extended periods of lactation protect against breast cancer development, but the mechanisms underlying this protection are unknown. We examined the effects of the milk protein alpha-casein over expression in the triple negative MDA-MB-231 breast cancer cell line. The effects of recombinant alpha-casein added exogenously to MDA-MB-231 breast cancer cells, and immortalised human fibroblasts were also investigated. We used transcriptional reporters to understand the signalling pathways downstream of alpha-casein in breast cancer cells and these fibroblasts that were activated by breast cancer cells. To extend our findings to the clinical setting, we analysed public gene expression datasets to further understand the relevance of these signalling pathways in triple negative breast cancer cells and patient samples. Finally, we used small molecular inhibitors to target relevant pathways and highlight these as potential candidates for the treatment of TN breast cancer. High levels of alpha-casein gene expression were predictive of good prognosis across 263 TNBC patient tumour samples. Alpha-casein over expression or exogenous addition reduces cancer stem cell (CSC) activity. HIF-1alpha was identified to be a key downstream target of alpha-casein, in both breast cancer cells and activated fibroblasts, and STAT transcription factors to be upstream of HIF-1alpha. Interestingly, HIF-1alpha is regulated by STAT3 in breast cancer cells, but STAT1 is the regulator of HIF-1alpha in activated fibroblasts. In analysis of 573 TNBC patient samples, alpha-casein expression, inversely correlated to HIF-1alpha, STAT3 and STAT1. STAT1 and STAT3 inhibitors target HIF-1alpha signalling in activated fibroblasts and MDA-MB-231 breast cancer cells respectively, and also abrogate CSC activities. Our findings provide an explanation for the protective effects of lactation in TNBC. Clinical data correlates high alpha-casein expression with increased recurrence-free survival in TNBC patients. Mechanistically, alpha-casein reduces breast cancer stem cell activity in vitro, and STAT3 and STAT1 were identified as regulators of pro-tumorigenic HIF-1alpha signalling in breast cancer cells and fibroblasts respectively.
Preparation of 93Mo solution using proton irradiated Nb

Abstract
93Mo is an important long-lived radionuclide in nuclear waste, and is required to be measured during the characterization of decommissioning waste. However, no commercial 93Mo solution is available to be calibrated and used as standard in the analysis of nuclear waste. This work presents a method for separation of 93Mo from Nb metal used in cyclotron as a target holder and irradiated with protons for long time. The separation of 93Mo from Nb matrix was implemented by combination of precipitation and chromatographic separation. The Nb matrix was first removed by precipitating oxides-hydroxides of Nb (e.g. Nb2O5) and then by Fe(OH)3 co-precipitation; Mo in the solution was purified using an alumina (Al2O3) column. A decontamination factor of ca. 105 was achieved for Nb. A pure carrier-free 93Mo solution was successfully prepared, and the 93Mo purity was verified by liquid scintillation spectrometry.
Seed and seedling characteristics of hybrid chestnuts (Castanea spp.) derived from a backcross blight-resistance breeding program

Published: September 2019

Abstract
American chestnut (Castanea dentata) was a foundation species in the eastern United States until chestnut blight (Cryphonectria parasitica) infestation resulted in range-wide catastrophic reduction. Since 1983, The American Chestnut Foundation (TACF) has engaged in a breeding program aimed at restoring C. dentata to the wild. The primary goal has been to introduce blight resistance from Castanea mollissima while recovering a C. dentata phenotype via successive backcrosses. To diversify the genetic base, state chapters of TACF have been producing BC3 and BC4 (third and fourth backcross) lines using C. dentata from across its native range. This study focuses on morphology and chemistry of seeds, and morphology and early growth of seedlings derived from BC3 and BC4 trees selected for blight resistance in state chapters. Our primary comparisons were among backcross, pure C. mollissima, and pure C. dentata lines. Seed traits included a suite of morphological characters known to differ between C. dentata and C. mollissima, as well as dry matter, total carbohydrate, sugar, protein, lipid, and phenolic content. Seedling traits included variables such as stem basal diameter and height, leaf variables such as number and area, and relative growth in key parameters such as stem volume. C. mollissima lines tended to differ significantly from C. dentata and backcross lines in most parameters, while C. dentata and backcross types tended to overlap broadly in traits. These results suggest that seed and seedling characteristics of backcross hybrids studied here are likely to be sufficiently similar to C. dentata for use in restoration programs.
Types of institutions and well-being of self-employed and paid employees in Europe
Authors: Fritsch Michael , Sorgner Alina , Wyrwich Michael 
Published: September 2019

AbstractThis paper analyzes the role of different types of institutions, such as entrepreneurship-facilitating entry conditions, labor market regulations, quality of government, and perception of corruption for individual well-being among self-employed and paid employed individuals. Well-being is operationalized by job and life satisfaction of individuals in 32 European countries measured by data from EU Statistics on Income and Living Conditions (EU-SILC). We find that institutions never affected both occupational groups in opposite ways. Our findings indicate that labor market institutions do not play an important role for well-being. The results suggest that fostering an entrepreneurial society in Europe is a welfare-enhancing strategy that benefits both, the self-employed and paid employees.
Dual Process Theories in Behavioral Economics and Neuroeconomics: a Critical Review
Authors: Grayot James D. 
Published: September 2019

AbstractDespite their popularity, dual process accounts of human reasoning and decision-making have come under intense scrutiny in recent years. Cognitive scientists and philosophers alike have come to question the theoretical foundations of the ‘standard view’ of dual process theory and have challenged the validity and relevance of evidence in support of it. Moreover, attempts to modify and refine dual process theory in light of these challenges have generated additional concerns about its applicability and refutability as a scientific theory. With these concerns in mind, this paper provides a critical review of dual process theory in economics, focusing on its role as a psychological framework for decision modeling in behavioral economics and neuroeconomics. I argue that the influx of criticisms against dual process theory challenge the descriptive accuracy of dualistic decision models in economics. In fact, the case can be made that the popularity of dual process theory in economics has less to do with the empirical success of dualistic decision models, and more to do with the convenience that the dual process narrative provides economists looking to explain-away decision anomalies. This leaves behavioral economists and neuroeconomists with something of a dilemma: either they stick to their purported ambitions to give a realistic description of human decision-making and give up the narrative, or they revise and restate their scientific ambitions.
Living collections: care and curation at Drosophila stock centres
Authors: BANGHAM JENNY 
Published: September 2019

AbstractBiological stock centres collect, care for and distribute living organisms for scientific research. In the 1990s, several of the world's largest Drosophila (fruit fly) stock centres were closed or threatened with closure. This paper reflects on why this happened, and uses the visibility of these endings to examine how stock centre collections are managed, who maintains them and how they are kept valuable and accessible to biologists. One stock centre came under threat because of challenges in caring for flies and monitoring the integrity of stocks. Another was criticized for keeping too many ‘archival’ stocks, an episode that reveals what it can mean for a living scientific collection to remain ‘relevant’ to a research community. That centre also struggled with the administrative and documentary practices that have proved crucial for sustaining a collection's meaning, value and availability. All of the stock centres in this story faced challenges of how to pay for care and curation, engaging with a problem that has been discussed by biologists and their funders since the 1940s: what are the best models for stock provision, and how could these models be changed?
The emergency department experience of patients with early pregnancy complications: A qualitative study

Published: September 2019

ABSTRACTObjectiveThe purpose of this qualitative study was to explore the experiences and perceptions of care of women treated for early pregnancy complications in a Canadian emergency department (ED) and early pregnancy clinic (EPC).MethodsWe conducted a descriptive qualitative study to understand the perceptions, meanings, and perspectives of women of 18 years and older who presented to the ED or EPC of an urban, tertiary care hospital with early pregnancy complications or loss. Using a semi-structured interview guide, a 45- to 60-minute telephone interview was conducted by a trained qualitative interviewer at 4 to 6 weeks after the ED visit. All interviews were digitally recorded and transcribed verbatim for analysis. Data analysis occurred in conjunction with data collection in order to continuously monitor emerging themes and general areas for further exploration. Interviews were conducted until thematic saturation had occurred.ResultsInterviews were completed with 30 women between June and August 2018. Three key themes arose: disconnect of the ED's role in the provision of care, normalization of a chaotic healthcare experience, and finding connection through the institution's EPC.ConclusionsPerspectives of women with early pregnancy complications highlight the ways in which ED care often does not meet the expectations or needs of patients and their families. The emotional complexity of this medical situation is often overlooked by ED staff and can produce encounters that are distressing. However, negative experiences were often mitigated by follow-up care in the institution's EPC.

East Asian winter monsoon evolution since the late Pliocene based on a pollen record from Lake Xingkai, northeast Asia
Authors: Xin Shouzhen , Shen Ji , Zhang Wenfang , Sun Weiwei , Xiao Xiayun 
Published: September 2019

AbstractA 328.58 m drill core (XK12) was recovered from lacustrine–alluvial sediments in the Xingkai Basin, northeast China, with the aim of obtaining a high-resolution pollen record of East Asian winter monsoon (EAWM) evolution since 3.6 Ma. An index based on the pollen record of thermophilous trees and terrestrial herbs is used as an indicator of winter temperature conditions controlled by the EAWM, at the glacial–interglacial scale. Primary age control was established based on lithostratigraphy and magnetostratigraphy, and then the pollen index was correlated to the LR04 global benthic δ18O record and finally tuned to Earth orbital obliquity to produce a high-resolution astronomical time scale. The pollen record indicates that the EAWM underwent two stepwise enhancements at 2.8 and 1.6 Ma. These events are consistent with paleoclimatic records of mean quartz grain size from the Chinese Loess Plateau, and they are also in accord with the initiation and intensification of Northern Hemisphere glaciation. Our findings suggest that the variability of the EAWM since 3.6 Ma was primarily controlled by changes in global ice volume and climatic cooling.
Lower Cretaceous Barents Sea strata: epicontinental basin configuration, timing, correlation and depositional dynamics

Published: September 2019

AbstractA comprehensive dataset is collated in a study on sediment transport, timing and basin physiography during the Early Cretaceous Period in the Boreal Basin (Barents Sea), one of the world’s largest and longest active epicontinental basins. Long-wavelength tectonic tilt related to the Early Cretaceous High Arctic Large Igneous Province (HALIP) set up a fluvial system that developed from a sediment source area in the NW, which flowed SE across the Svalbard archipelago, terminating in a low-accommodation shallow sea within the Bjarmeland Platform area of the present-day Barents Sea. The basin deepened to the SE with a ramp-like basin floor with gentle dip. Seismic data show sedimentary lobes with internal clinoform geometry that advanced from the NW. These lobes interfingered with, and were overlain by, another younger depositional system with similar lobes sourced from the NE. The integrated data allow mapping of architectural patterns that provide information on basin physiography and control factors on source-to-sink transport and depositional patterns within the giant epicontinental basin. The results highlight how low-gradient, low-accommodation sediment transport and deposition has taken place along proximal to distal profiles for several hundred kilometres, in response to subtle changes in base level and by intra-basinal highs and troughs. Long-distance correlation along depositional dip is therefore possible, but should be treated with caution to avoid misidentification of timelines for diachronous surfaces.
