Nitrogen use efficiency of 15N urea applied to wheat based on fertiliser timing and use of inhibitors
Authors: Wallace Ashley J. , Armstrong Roger D. , Grace Peter R. , Scheer Clemens , Partington Debra L.
Published: October 2019

Improving fertiliser nitrogen (N) use efficiency is essential to increase productivity and avoid environmental damage. Using a 15N mass balance approach, we investigated the effects of five N fertiliser management strategies to test the hypothesis that increasing uptake of applied N by wheat improves productivity and reduces loss of N in a semi-arid environment. Three experiments were conducted between 2012 and 2014. Treatments included urea application (50 kg N/ha) at sowing with and without nitrification inhibitor (3,4-dimethylpyrazole phosphate, DMPP) and surface broadcast with and without urease inhibitor (n-butyl thiophosphoric triamide, NBPT) at the end of tillering plus an unfertilised control. It was found that deferring fertiliser application until the end of tillering decreased losses of fertiliser N (35–52%) through increasing uptake by the crop and or recovery in the soil at harvest, while maintaining yield except when rainfall following application was low. In this case, deferring application reduced fertiliser uptake (− 71%) and grain yield (− 18%) and increased recovery of N in the soil (+ 121%). Use of DMPP or NBPT reduced N loss where seasonal conditions were conducive to denitrification during winter (DMPP) and volatilisation or denitrification later in the season (NBPT). Their effect on grain yield was less significant; DMPP increased yield (+ 3–31%) in all years and NBPT increased yield (+ 7–11%) in 2 of 3 years compared to unamended urea. The majority of crop N uptake was supplied from soil reserves and as a result, crop recovery of applied N was not strongly related to grain yield response.
Principles of Information Processing and Natural Learning in Biological Systems
Authors: Slijepcevic Predrag
Published: October 2019

The key assumption behind evolutionary epistemology is that animals are active learners or ‘knowers’. In the present study, I updated the concept of natural learning, developed by Henry Plotkin and John Odling-Smee, by expanding it from the animal-only territory to the biosphere-as-a-whole territory. In the new interpretation of natural learning the concept of biological information, guided by Peter Corning’s concept of “control information”, becomes the ‘glue’ holding the organism–environment interactions together. The control information guides biological systems, from bacteria to ecosystems, in the process of natural learning executed by the universal algorithm. This algorithm, summarized by the acronym IGPT (information-gain-process-translate) incorporates natural cognitive methods including sensing/perception, memory, communication, and decision-making. Finally, the biosphere becomes the distributed network of communicative interactions between biological systems termed the interactome. The concept of interactome is based on Gregory Bateson’s natural epistemology known as the “ecology of mind”. Mimicking Bateson’s approach, the interactome may also be designated “physiology of mind”—the principle behind regulating the biosphere homeostasis.
Digital Economy as a Factor in the Technological Development of the Mineral Sector
Authors: Litvinenko V. S.
Published: October 2019

This article describes the impact of the global digital economy on the technological development of the mineral sector in the world. Due to the different specifics of the legislative bases of the investigated regions, such as the USA, China, EU, and Africa, the development of digital transformation is presented on the example of the Russian Federation in the context of world trends. The article presents an analysis of the possibilities of using straight-through digital technology in prospecting, design, development, and use of mineral resources. It describes a structure promoting the development of applied digital technology through research–education centers and international competence centers. This structure would allow forming the new competencies for personnel working in the digital economy. The underfunding of the information and computing infrastructure could be a significant challenge to the digital transformation of the economy. Creating the conditions for a reliable and secure process of generating, storing, and using data is the basis for protection from the cybersecurity hazard that could act as a brake on technology advancement. This article discusses the organizational and technological priorities of the development of the mineral resource sector on the example of the Russian Federation. The challenges for the mineral resource complex resulting from global changes can be taken on through technological changes of the industry. The article gives a thorough description of issues related to technological developments in the raw materials sector, oil refining industry, development of integrated and advanced mineral processing systems, and the use of household and industrial wastes. The research presents basic technology contributing to sustainable development, starting from exploration and production forecasting and up to sustainable planning and distribution of material and energy resources based on real-time data. It also pays special attention to the possibilities of creating digital platforms for the mineral sector. Digital integration, combining research areas, personnel, processes, users, and data will create conditions for scientific and technological achievements and breakthroughs, providing scientific and economic developments in related industries and, above all, in the global mineral and raw materials market.
Predicting plant available phosphorus using infrared spectroscopy with consideration for future mobile sensing applications in precision farming
Authors: Pätzold Stefan , Leenen Matthias , Frizen Peter , Heggemann Tobias , Wagner Peter , Rodionov Andrei
Published: October 2019

Phosphorus (P) fertilisation recommendations rely primarily on soil content of plant available P (Pavl) that vary spatially within farm fields. Spatially optimized P fertilisation for precision farming requires reliable, rapid and non-invasive Pavl determination. This laboratory study aimed to test and to compare visible-near infrared (Vis–NIR) and mid-infrared (MIR) spectroscopy for Pavl prediction with emphasis on future application in precision agriculture. After calibration with the conventional calcium acetate lactate (CAL) extraction method, limitations of Vis–NIRS and MIRS to predict Pavl were evaluated in loess topsoil samples from different fields at six localities. Overall calibration with 477 (Vis–NIRS) and 586 (MIRS) samples yielded satisfactory model performance (R2 0.70 and 0.72; RPD 1.8 and 1.9, respectively). Local Vis–NIRS models yielded better results with R2 up to 0.93 and RPD up to 3.8. For MIRS, results were comparable. However, an overall model to predict Pavl on independent test data partly failed. Sampling date, pre-crop harvest residues and fertilising regime affected model transferability. Varying transferability could partly be explained after deriving the cellulose absorption index from the Vis–NIR spectra. In 62 (Vis–NIRS) and 67% (MIRS) of all samples, prediction matched the correct Pavl content class. Rapid discrimination between high, optimal and low P classes could be carried out on many samples from single fields thus marking an improvement over the common practice. However, Pavl determination by means of IR spectroscopy is not yet satisfactory for determination of precision fertilizer dosage. For introduction into agricultural practice, a standardized sampling protocol is recommended to help achieve reliable spectroscopic Pavl prediction.
Patterns of Trust and Subjective Well-Being Across Europe: New Insights from Repeated Cross-Sectional Analyses Based on the European Social Survey 2002–2016
Authors: Glatz Christoph , Eder Anja
Published: October 2019

This paper offers elaborate analyses regarding the effects of social- as well as institutional trust as parts of social capital on subjective well-being (SWB) by using data from the European Social Survey, including 36 countries and eight time-points between 2002 and 2016. We analyze (1) The development of trust and SWB on the aggregate level; (2) The effect of trust on SWB on the individual cross-sectional level; and (3) The longitudinal and cross-sectional effect of trust on SWB on the aggregate level while considering control variables based on previous research. We observe a weak positive trend regarding social trust as well as SWB over time, but no significant change in institutional trust. However, trends are far from homogeneous across countries. In accordance to previous studies, we find a positive effect of social trust on SWB. This effect holds on the individual cross-sectional level for every participating country, but also on the longitudinal level. In view of institutional trust, we see a positive effect on SWB on the individual and aggregate cross-sectional level, but not over time. Thus, this study particularly sheds new light on this relation, indicating that it´s cross-sectional relation is due to confounding variables. Moreover, we observe no relation between economic growth and SWB after controlling for unemployment, but a positive effect of decreasing unemployment and inflation on SWB. Our data suggests that establishing an environment with high social trust across Europe would be rewarded with a happy society.
Excess H, Suppressed He, and the Abundances of Elements in Solar Energetic Particles
Authors: Reames Donald V.
Published: October 2019

Recent studies of the abundances of H and He relative to those of heavier ions in solar energetic particle (SEP) events suggest new features in the underlying physics. Impulsive SEP events, defined by uniquely large enhancements of Fe/O, emerge from magnetic reconnection in solar jets. In small, “pure,” shock-free, impulsive SEP events, protons with mass-to-charge ratio $A/Q = 1$A/Q=1 fit the power-law dependence of element abundance enhancements versus$A/Q$A/Q extrapolated from the heavier elements $6 \leq Z \leq 56$6≤Z≤56. Sometimes these events have order-of-magnitude suppressions of He, even though H fits with heavier elements, perhaps because of the slower ionization of He during a rapid rise of plasma from the chromosphere. In larger impulsive SEP events, He fits, but there are large proton excesses relative to the power-law fit of $Z > 2$Z>2 ions, probably because associated coronal mass ejections (CMEs) drive shock waves fast enough to reaccelerate the impulsive SEPs but also to sample protons from the ambient solar plasma. In contrast, gradual SEP events are accelerated by wide, fast CME-driven shock waves, but those with smaller, weaker shocks, perhaps quasi-perpendicular, favor impulsive suprathermal residue left by many previous jets, again supplemented with excess protons from ambient coronal plasma. In the larger, more common gradual SEP events, faster, stronger shock waves sample the ambient coronal plasma more deeply, overwhelming any impulsive-ion component, so that proton abundances again fit the same power-law distribution as all other elements. Thus, studies of the power-law behavior in $A/Q$A/Q of SEP element abundances give compelling new information on the varying physics of SEP acceleration and properties of the underlying corona.
Statistical Analysis and Catalog of Non-polar Coronal Holes Covering the SDO-Era Using CATCH

Published: October 2019

Coronal holes are usually defined as dark structures seen in the extreme ultraviolet and X-ray spectrum which are generally associated with open magnetic fields. Deriving reliably the coronal hole boundary is of high interest, as its area, underlying magnetic field, and other properties give important hints as regards high speed solar wind acceleration processes and compression regions arriving at Earth. In this study we present a new threshold-based extraction method, which incorporates the intensity gradient along the coronal hole boundary, which is implemented as a user-friendly SSW-IDL GUI. The Collection of Analysis Tools for Coronal Holes (CATCH) enables the user to download data, perform guided coronal hole extraction and analyze the underlying photospheric magnetic field. We use CATCH to analyze non-polar coronal holes during the SDO-era, based on 193 Å filtergrams taken by the Atmospheric Imaging Assembly (AIA) and magnetograms taken by the Heliospheric and Magnetic Imager (HMI), both on board the Solar Dynamics Observatory (SDO). Between 2010 and 2019 we investigate 707 coronal holes that are located close to the central meridian. We find coronal holes distributed across latitudes of about ${\pm}\, 60^{\circ}$±60∘, for which we derive sizes between $1.6 \times 10^{9}$1.6×109 and $1.8 \times 10^{11}\mbox{ km}^{2}$1.8×1011 km2. The absolute value of the mean signed magnetic field strength tends towards an average of $2.9\pm 1.9$2.9±1.9 G. As far as the abundance and size of coronal holes is concerned, we find no distinct trend towards the northern or southern hemisphere. We find that variations in local and global conditions may significantly change the threshold needed for reliable coronal hole extraction and thus, we can highlight the importance of individually assessing and extracting coronal holes.
Pharmacodynamic assessment of prasugrel and clopidogrel in patients with non-cardioembolic stroke: a multicenter, randomized, active-control clinical trial
Authors: Yamaguchi Takenori , Shirai Toshiaki , Yoshiba Satoshi , Abe Kenji , Ikeda Yasuo
Published: October 2019

Prasugrel, a novel P2Y12receptor antagonist, has been shown to be more effective than clopidogrel for preventing cardiovascular events in patients with acute coronary syndromes undergoing percutaneous coronary intervention. We investigated the dose–response antiplatelet effects of prasugrel compared with clopidogrel in Japanese patients with non-cardioembolic stroke. The influence of cytochrome P450 (CYP) polymorphisms on the antiplatelet effects of both drugs was also compared. In this multicenter randomized active-control comparative study, patients were randomized to receive prasugrel 2.5 mg, 5 mg, or 7.5 mg (double blind) or clopidogrel 75 mg (open label) once daily for 14 days. The primary endpoint was inhibition of platelet aggregation (IPA) in response to adenosine diphosphate 20 μM within 8 h of study drug administration on day 14. Of the 66 patients randomized, data from 63 (prasugrel 2.5 mg, 5 mg, and 7.5 mg groups,n = 14, 16, and 18, respectively; clopidogrel group,n = 15) were used in the pharmacodynamic assessment. IPA (arithmetic mean ± SD) after prasugrel administration increased dose-dependently (33 ± 9%, 44 ± 11%, and 53 ± 14%, at 2.5 mg, 5 mg, and 7.5 mg, respectively) and was higher in these groups than after clopidogrel (23 ± 16%). In a subgroup of CYP2C19 intermediate metabolizers, IPA was higher in the prasugrel 5 mg and 7.5 mg groups than in the clopidogrel group. No death or serious adverse events were reported. Prasugrel was well tolerated at doses up to 7.5 mg/day and had antiplatelet effects higher than those of clopidogrel 75 mg/day. CYP2C19 polymorphisms may have reduced clopidogrel-induced IPA.
On the number of Monte Carlo runs in comparative probabilistic LCA
Authors: Heijungs Reinout
Published: October 2019

Introduction

The Monte Carlo technique is widely used and recommended for including uncertainties LCA. Typically, 1000 or 10,000 runs are done, but a clear argument for that number is not available, and with the growing size of LCA databases, an excessively high number of runs may be a time-consuming thing. We therefore investigate if a large number of runs are useful, or if it might be unnecessary or even harmful.

Probability theory

We review the standard theory or probability distributions for describing stochastic variables, including the combination of different stochastic variables into a calculation. We also review the standard theory of inferential statistics for estimating a probability distribution, given a sample of values. For estimating the distribution of a function of probability distributions, two major techniques are available, analytical, applying probability theory and numerical, using Monte Carlo simulation. Because the analytical technique is often unavailable, the obvious way-out is Monte Carlo. However, we demonstrate and illustrate that it leads to overly precise conclusions on the values of estimated parameters, and to incorrect hypothesis tests.

Numerical illustration

We demonstrate the effect for two simple cases: one system in a stand-alone analysis and a comparative analysis of two alternative systems. Both cases illustrate that statistical hypotheses that should not be rejected in fact are rejected in a highly convincing way, thus pointing out a fundamental flaw.

Discussion and conclusions

Apart form the obvious recommendation to use larger samples for estimating input distributions, we suggest to restrict the number of Monte Carlo runs to a number not greater than the sample sizes used for the input parameters. As a final note, when the input parameters are not estimated using samples, but through a procedure, such as the popular pedigree approach, the Monte Carlo approach should not be used at all.
Seasonal dynamics of soil microbial biomass C and N of Keteleeria fortunei var. cyclolepis forests with different ages

Published: October 2019

Soil microbial biomass is an important indicator to measure the dynamic changes of soil carbon pool. It is of great significance to understand the dynamics of soil microbial biomass in plantation for rational management and cultivation of plantation. In order to explore the temporal dynamics and influencing factors of soil microbial biomass of Keteleeria fortunei var. cyclolepis at different stand ages, the plantation of different ages (young forest, 5 years; middle-aged forest, 22 years; mature forest, 40 years) at the Guangxi Daguishan forest station of China were studied to examine the seasonal variation of their microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) by chloroform fumigation extraction method. It was found that among the forests of different age, MBC and MBN differed significantly in the 0–10 cm soil layer, and MBN differed significantly in the 10–20 cm soil layer, but there was no significant difference in MBC for the 10–20 cm soil layer or in either MBC or MBN for the 20–40 cm soil layer. With increasing maturity of the forest, MBC gradually decreased in the 0–10 cm soil layer and increased firstly and then decreased in the 10–20 cm and 20–40 cm soil layers, and MBN increased firstly and then decreased in all three soil layers. As the soil depth increased, both MBC and MBN gradually decreased for all three forests. The MBC and MBN basically had the same seasonal variation in all three soil layers of all three forests, i.e., high in the summer and low in the winter. Correlation analysis showed that MBC was significantly positively correlated with soil organic matter, total nitrogen, and soil moisture, whereas MBN was significantly positively correlated with soil total nitrogen. It showed that soil moisture content was the main factor determining the variation of soil microbial biomass by Redundancy analysis. The results showed that the soil properties changed continuously as the young forest grew into the middle-aged forest, which increased soil microbial biomass and enriched the soil nutrients. However, the soil microbial biomass declined as the middle-age forest continued to grow, and the soil nutrients were reduced in the mature forest.

Published: October 2019

Salmonellachallenge leads to systemic responses that induce the hypozincaemia in mice, which is considered a vital strategy againstSalmonellainvasion. However, it is not yet known if this phenomenon occurs in broilers. To investigate the change in zinc homeostasis of broilers againstSalmonellachallenge, 1-day-old male broilers were fed with the basal diet for 7 days. Afterwards, broilers were orally inoculated with either 0 or 0.5 × 108 CFUSalmonellaTyphimurium (ST). The serum and selected tissues ofSalmonella-challenged and non-challenged broilers were collected at 1, 3 and 7 days post-challenge for zinc homeostasis analysis. Our results showed thatSalmonellachallenge results in hypozincaemia (serum zinc decrease and liver zinc increase) via modulating the systemic zinc homeostasis of broilers. A profound, zinc transporter–mediated zinc absorption and redistribution affecting zinc homeostasis provided a mechanistic explanation for this phenomenon. In addition, we found that the zinc importersZip5,Zip10,Zip11,Zip12,Zip13andZip14were mainly downregulated inSalmonella-challenged broilers to reduce zinc absorption in the duodenum, while theZip14mRNA expression was upregulated to redistribute zinc into the liver. Collectively, these findings reveal that broilers counteractSalmonellainfection via modulating their systemic zinc homeostasis.
Exploring the evolving concept of ‘patient ownership’ in the era of resident duty hour regulations—experience of residents and faculty in an internal medicine night float system
Authors: Masson Vanessa , Snell Linda , Dolmans Diana , Sun Ning-Zi
Published: October 2019

Background Despite the use of ‘patient ownership’ as an embodiment of professionalism and increasing concerns over its loss among trainees, how its development in residents has been affected by duty hour regulations has not been well described. In this qualitative study, we aim to outline the key features of patient ownership in internal medicine, factors enabling its development, and how these have been affected by the adoption of a night float system to comply with duty hour regulations.

Methods In this qualitative descriptive study, we interviewed 18 residents and 12 faculty internists at one university centre and conducted a thematic analysis of the data focused on the concept of patient ownership.

Results We identified three key features of patient ownership: personal concern for patients, professional capacity for autonomous decision-making, and knowledge of patients’ issues. Within the context of a night float system, factors that facilitate development of patient ownership include improved fitness for duty and more consistent interactions with patients/families resulting from working the same shift over consecutive days (or nights). Conversely, the increase in patient handovers, if done poorly, is a potential threat to patient ownership development. Trainees often struggle to develop ownership when autonomy is not supported with supervision and when role-modelling by faculty is lacking.

Discussion These features of patient ownership can be used to frame discussions when coaching trainees. Residency programs should be mindful of the downstream effects of shift-based scheduling. We propose strategies to optimize factors that enable trainee development of patient ownership.
Alzheimer's disease mechanisms in peripheral cells: Promises and challenges
Authors: Trushina Eugenia
Published: October 2019

Introduction

Development of efficacious therapeutic interventions for Alzheimer's disease (AD) is hampered by the lack of understanding early disease mechanisms, biomarkers, and models that mimic complex pathophysiology of human disease.

Methods

This article aims to assess to what extent peripheral cells recapitulate molecular mechanisms altered in the brain and could be used as translational models for the development of individualized medicine for AD.

Results

Multiple studies suggest that AD is a systemic disorder with an active crosstalk between brain and periphery where multiple pathways altered in the brain cells are also affected in plasma, cerebrospinal fluid, and other peripheral cells of AD patients.

Discussion

Additional studies to validate molecular mechanisms in peripheral cells using advanced system biology techniques and well‐characterized cohorts of AD patients together with the development of standardized protocols should be considered to support the application of peripheral cells in AD research.
Why Does Kant Think We Must Believe in the Immortal Soul?
Authors: Tizzard Jessica
Published: October 2019

Making sense of Kant’s claim that it is morally necessary for us to believe in the immortal soul is a historically fraught issue. Commentators typically reject it, or take one of two paths: they either restrict belief in the immortal soul to our subjective psychology, draining it of any substantive rational grounding; or make it out to be a rational necessity that morally interested beings must accept on pain of contradiction. Against these interpreters, I argue that on Kant’s view, belief in our immortality is necessary because it further determines and enriches the cognitive content contained in the concept of the highest good. Through this sharpened conceptual content, we acquire the resources to withstand theoretical skepticism about our moral vocation.
Publicity, reciprocity, and incentives
Authors: Lister Andrew
Published: October 2019

This paper mounts a partial defense of the basic structure objection to the egalitarian criticism of productive incentives. The defense is based on the claim that some duties of justice are subject to a reciprocity condition. The paper develops this position via an examination of the debate between Andrew Williams and G. A. Cohen on publicity and incentives. Reciprocity is an intrinsic feature of a relational conception of social justice, not simply a requirement of stability. Not all duties are conditional on reciprocity because some duties are owed to third parties, as well as to their primary targets. Some forms of exploitation may be unconditionally wrong, but not the specific kind of exploitation at stake when talented individuals accept market wages.

Published: October 2019

Introduction:

News media play an important role in raising public awareness, framing public opinions, affecting policy formulation, and acknowledgment of public health issues. Traditional qualitative content analysis for news sentiments and focuses are time-consuming and may not efficiently convey sentiments nor the focuses of news media.

Methods:

We used descriptive statistics and state-of-art text mining to conduct sentiment analysis and topic modeling, to efficiently analyze over 3 million Reuters news articles during 2007–2017 for identifying their coverage, sentiments, and focuses for public health issues. Based on the top keywords from public health scientific journals, we identified 10 major public health issues (i.e., “air pollution,” “alcohol drinking,” “asthma,” “depression,” “diet,” “exercise,” “obesity,” “pregnancy,” “sexual behavior,” and “smoking”).

Results:

The news coverage for seven public health issues, “Smoking,” “Exercise,” “Alcohol drinking,” “Diet,” “Obesity,” “Depression,” and “Asthma” decreased over time. The news coverage for “Sexual behavior,” “Pregnancy,” and “Air pollution” fluctuated during 2007–2017. The sentiments of the news articles for three of the public health issues, “exercise,” “alcohol drinking,” and “diet” were predominately positive and associated such as “energy.” Sentiments for the remaining seven public health issues were mainly negative, linked to negative terms, e.g., diseases. The results of topic modeling reflected the media’s focus on public health issues.

Conclusions:

Text mining methods may address the limitations of traditional qualitative approaches. Using big data to understand public health needs is a novel approach that could help clinical and translational science awards programs focus on community-engaged research efforts to address community priorities.
Laminarin-rich extract improves growth performance, small intestinal morphology, gene expression of nutrient transporters and the large intestinal microbial composition of piglets during the critical post-weaning period

Published: October 2019

The identification of natural bioactive compounds which can prevent the post-weaning growth check and enhance gastrointestinal health in the absence of in-feed medications is an urgent priority for the swine industry. The objective of this experiment was to determine the effects of increasing dietary inclusion levels of laminarin in the first 14 d post-weaning on pig growth performance and weaning associated intestinal dysfunction. At weaning, ninety-six pigs (8·4 (sd 1·09) kg) (meatline boars × (large white × landrace sows)) were blocked by live weight, litter and sex and randomly assigned to: (1) basal diet; (2) basal + 100 parts per million (ppm) laminarin; (3) basal + 200 ppm laminarin and (4) basal + 300 ppm laminarin (three pigs/pen). The appropriate quantity of a laminarin-rich extract (65 % laminarin) was added to the basal diet to achieve the above dietary inclusion levels of laminarin. After 14 d of supplementation, eight pigs from the basal group and the best-performing laminarin group were euthanised for sample collection. The 300 ppm laminarin group was selected as this group had higher ADFI compared with all other groups and higher ADG than the basal group (P < 0·05). Laminarin supplementation increased villus height in the duodenum and jejunum (P < 0·05). Laminarin supplementation increased the expression of SLC2A8/GLUT8 in the duodenum, SLC2A2/GLUT2, SLC2A7/GLUT7, SLC15A1/PEPT1 and FABP2 in the jejunum and SLC16A1/MCT1 in the colon. Laminarin supplementation reduced Enterobacteriaceae numbers in the caecum (P < 0·05) and increased lactobacilli numbers (P < 0·05), total volatile fatty acid concentrations and the molar proportions of butyrate (P < 0·01) in the colon. In conclusion, 300 ppm laminarin from a laminarin-rich extract has potential, as a dietary supplement, to improve performance and prevent post-weaning intestinal dysfunction.
PYTHAGORAS AND ISIS
Authors: Huffman Carl
Published: October 2019

In this article I want to clarify the text of one of the short maxims assigned to Pythagoras in the ancient tradition, which are known as symbola or acusmata. Before I turn to the acusma in question, it is important to understand the context in which it appears. It occurs in Chapter 17 of Book 4 of Aelian's Historical Miscellany (ποικίλη ἱστορία). Aelian's work was written in the early third century a.d. in Rome, and is a ‘miscellaneous collection of anecdotes and historical material’. It consists of short chapters, usually a page or less long, that are for the most part independent of one another. Chapter 17 of Book 4 is about a page long and is devoted to the sayings and doings of Pythagoras. There is no particular connection between it and the surrounding chapters, and it is clearly meant to stand on its own. The preceding chapter (16) tells us that if we went to Callias for guidance he would turn us into drinkers, … if to Alcibiades, arrogant cheats, if to Demosthenes, orators, … if to Aristides, just men, … if to Socrates, wise men. The following chapter (18) recounts an anecdote about Plato's arrival in Sicily and his reception by the tyrant Dionysius the Younger. The chapter that I am concerned with, Chapter 17, begins by asserting that Pythagoras taught that his ‘lineage was superior to that of ordinary mortals’. This is followed by a list of superhuman acts and traits of Pythagoras, for example his ability to be in Metapontum and Croton at the same time and his golden thigh. The second two-thirds of the chapter are then devoted to the miscellaneous teachings of Pythagoras. Most of these take the form of the brief taboos and maxims known elsewhere as symbola or acusmata, among which is the text on which I want to focus here.
Gendered Nationalism and the 2016 US Presidential Election: How Party, Class, and Beliefs about Masculinity Shaped Voting Behavior
Authors: Deckman Melissa , Cassese Erin
Published: October 2019

We examine which Americans were likely to believe that American society has grown “too soft and feminine,” a concept we have characterized as gendered nationalism, and how such gendered nationalist attitudes influenced voting behavior in the 2016 presidential race. Our analysis shows that party, gender, education, and class shaped attitudes about gendered nationalism: Republicans, men, and members of the working class were more likely to support gendered nationalist views. We identify a strong, significant relationship between gendered nationalist attitudes and the probability of voting for Donald Trump, even after controlling for partisanship, ideology, race, religion, and other factors. Moreover, gender differences in candidate support were largely driven by gender differences in beliefs that the United States has grown too soft and feminine. Our research adds to the growing scholarly evidence indicating that gendered beliefs are likely to have a bigger impact on American political behavior than a voter's gender alone.
Creating a Computerized Instrument for the Assessment of Blood-Injury-Injection Phobia
Authors: Ruiz-García Antonio , Valero-Aguayo Luis , Hurtado-Melero Félix
Published: October 2019

A new computerized instrument (the Multimedia Behavioral Avoidance Test, or MBAT) for blood-injury-injection phobia (BII) assessment is presented. Analogous stimuli such as images and videos can also elicit anxiety responses; thus, they can be used for the assessment of phobia. The MBAT was applied to participants via computer, and subjective anxiety responses and time latency were recorded. The MBAT was composed of 30 original images and 30 videos related to blood, injury and injections. The MBAT was compared with other pencil-and-paper questionnaires for BII phobia, and heart rate was also measured with a pulsioximeter. The participants included 160 students and professionals (34.5% males, 65.6% females; mean 28.6 years old). The results showed a high reliability for internal consistency in images and videos (α = .98 both), with a single factor that groups all the items. In addition, the MBAT had high concurrent validity (r = .78 to .85) with the different anxiety scales compared. The MBAT diagnosed 12 participants with possible BII phobia. It is a useful instrument in the assessment of this kind of phobia because it is easier and quicker than pencil-and-paper questionnaires, it uses more objective measurements, and it is useful in planning subsequent exposure with images and videos.
The Longitudinal Israeli Study of Twins (LIST) Reaches Adolescence: Genetic and Environmental Pathways to Social, Personality and Moral Development
Authors: Vertsberger Dana , Abramson Lior , Knafo-Noam Ariel
Published: October 2019

The Longitudinal Israeli Study of Twins (LIST) focuses on the developmental, genetic and environmental contributions to individual differences in children’s and adolescents’ social behavior. Key variables have been empathy, prosocial behavior, temperament and values. Another major goal of LIST has been to study gene–environment correlations, mainly concerning parenting. LIST includes 1657 families of Hebrew-speaking Israeli twins who have participated at least once in the study. Children’s environment and their development are assessed in a multivariate, multimethod fashion, including observed, parent-reported and self-reported data. The current article summarizes and updates recent findings from LIST. For example, LIST provided evidence for the heritability of human values with the youngest sample to date, and the first genetic investigation of adolescents’ identity formation. Finally, future aims of LIST are discussed.

Die Bereitschaft von beruflich Pflegenden, neue Technologien einzusetzen, wird häufig gering eingeschätzt, insbesondere für ältere und weibliche Pflegende, die einen hohen Anteil in der ambulanten Pflege darstellen. Belastbare Daten zur Technikbereitschaft in der ambulanten Pflege liegen jedoch für den deutschsprachigen Raum bislang nicht vor. Ziel: Der Beitrag stellt die Ergebnisse aus zwei standardisierten Erhebungen zur Technikbereitschaft in der ambulanten Pflege vor. Methode: Zur Datenerhebung wurde das standardisierte Assessment zur Erfassung der Technikbereitschaft eingesetzt, welches Technikbereitschaft über die Facetten „Technikakzeptanz“, „Technikkompetenzüberzeugung“ und „Technikkontrollüberzeugung“ bestimmt (26-1Neyer, Felber & Gebhardt, 2012). Eine erste Datenerhebung (2013) konzentrierte sich auf Pflegedienste im Bundesland Niedersachsen (n = 263), eine zweite Erhebung (2017) wurde bei einem bundesweit agierenden Anbieter (n = 593) vorgenommen. Ergebnisse: Die Ergebnisse der vorliegenden Untersuchungen liefern erstmals differenzierte Einsichten in Fragen der Technikbereitschaft in der ambulanten Pflege in Deutschland. Es ergeben sich insbesondere Hinweise auf Unterschiede in der Technikbereitschaft in der ambulanten Pflege in Abhängigkeit von der Altersgruppe der Befragten. Schlussfolgerung: Die Einführung neuer Technologien in den Alltag beruflich Pflegender benötigt demografiesensible Konzepte zur Vorbereitung und Begleitung der Nutzerinnen und Nutzer.

Oceanic heat strongly influences the glaciers and ice shelves along West Antarctica. Prior studies show that the subsurface onshore heat flux from the Southern Ocean on the shelf occurs through deep, glacially carved channels. The mechanisms enabling the export of colder shelf waters to the open ocean, however, have not been determined. Here, we use ocean glider measurements collected near the mouth of Marguerite Trough (MT), west Antarctic Peninsula, to reveal shelf‐modified cold waters on the slope over a deep (2,700 m) offshore topographic bank. The shelf hydrographic sections show subsurface cold features (θ <=1.5 °C), and associated potential vorticity fields suggest a significant instability‐driven eddy field. Output from a high‐resolution numerical model reveals offshore export modulated by small (6 km), cold‐cored, cyclonic eddies preferentially generated along the slope and at the mouth of MT. While baroclinic and barotropic instabilities appear active in the surrounding open ocean, the former is suppressed along the steep shelf slopes, while the latter appears enhanced. Altimetry and model output reveal the mean slope flow splitting to form an offshore branch over the bank, which eventually forms a large (116 km wide) persistent lee eddy, and an onshore branch in MT. The offshore flow forms a pathway for the small cold‐cored eddies to move offshore, where they contribute significantly to cooling over the bank, including the large lee eddy. These results suggest eddy fluxes, and topographically modulated flows are key mechanisms for shelf water export along this shelf, just as they are for the shoreward warm water transport.

On 3 January 2019, the Chang'e‐4 (CE‐4) touched down on the Von Karman crater located inside the South Pole‐Aitken Basin, providing for the first time the opportunity for in situ measurements of the lunar regolith at the farside of the Moon. The CE‐4 ground penetrating radar reveals that fine‐grained regolith, coarse impact ejecta, and fractured bedrocks lie beneath the exploration path of the Yutu‐2 rover. The variations of regolith permittivity with depth and the radargrams indicate that the CE‐4 site has a fine‐grained regolith layer thickness of 11.1 m, which is about 1.3–3 times higher than the in situ measurement results at the Apollo and Chang'e‐3 (CE‐3) sites except for Apollo 16, possibly due to a faster weathering rate of ejecta deposits compared with coherent basalt substrates. The penetration depth of CE‐4 is about 2.85 times (in terms of round‐way delay) deeper than CE‐3, probably due to the differences in abundances of ilmenite and rocks in the regolith.
Signatures of the Arctic Stratospheric Ozone in Northern Hadley Circulation Extent and Subtropical Precipitation

Previous studies showed that Antarctic ozone could modulate the Hadley circulation (HC) and precipitation in the Southern Hemisphere. However, whether and how, if any, Arctic stratospheric ozone (ASO) modulates the northern HC and subtropical precipitation remains unclear. We found an out‐of‐phase relationship between the northern HC extent (HCE) and ASO during boreal spring on interannual timescales during 1979–2014. Decreased (increased) ASO tends to result in an equatorward (poleward) shift of HCE by +0.67° (−0.45°) latitude per one standard deviation of decreased (increased) ASO year. Observational analysis and model simulations show that increased ASO leads to an equatorward shift of HCE and subtropical moistening via weakened eddy momentum flux and decreased subtropical static stability, accompanied with negative eddy momentum flux divergence anomalies and northward meridional wind anomalies over the subtropics. Our results may help to understand the linkage between the Arctic and midlatitudes, especially important for the subtropical precipitation and hydrological cycle.

The Multi‐angle Imaging SpectroRadiometer (MISR) provides measurements over a wider scattering‐angle range for a given location than a cross‐track scanning sensor such as the MODerate resolution Imaging Spectroradiometer (MODIS). Based on a full year (2013) of fused MISR‐MODIS datasets, we develop a variable surface roughness model for ice particles with the goal of identifying the optimal degree of roughness in the ice model for a given pixel containing single‐layer ice clouds. For the MISR‐MODIS observations over oceans, severe roughness values are often selected for a pixel when optical thickness (τ) and particle effective radius (Reff) are large in conjunction with larger cloud heterogeneity index (Hσ) or a warmer cloud top temperature. Furthermore, τ, Reff, and ice water path are retrieved with the optimal model and compared to operational MODIS Collection 6 (MC6) products that assume a constant roughness. In general, the retrievals based on the present optimal model lead to greater consistency with MISR measurements, and result in larger median τ by 10.1% and smaller median Reff by 6.5% but almost identical ice water path in comparison with the MC6 counterparts. The higher average τ value is caused by a slightly larger number of large τ cases, but the smaller average Reff value is due to the shifting of the retrieved Reff value toward smaller values by approximately 2–4 μm in comparison to the MC6 distribution over all seasons. Both τ retrievals have similar regional and monthly variations, but a larger annual cycle of Reff is associated with the optimal model.
Volcanic Impacts Dominate Bidecadal‐Multidecadal Temperature Variations During the Late Holocene in Northern Fennoscandia
Authors: Rinne Juhani , Alestalo Mikko
Published: October 2019

A reconstruction of summer temperatures during two millennia in Northern Fennoscandia has been studied and 79 abrupt cold periods have been identified. Data regarding the volcanic eruptions are not a priori used. During 1750–2000 all of the abrupt, cold periods could posteriori be connected to candidate years of volcanic eruptions. It is concluded that the 79 abrupt cold periods are mainly, if not all, postvolcanic ones. Local impact of weaker, less global (Icelandic) or some unknown eruptions is evident in the results. In addition to the short cold periods, we found 42 longer bidecadal‐multidecadal oscillations during 50–1980 AD. The short abrupt cold periods and the longer oscillations were characterized as the atmospheric and oceanic responses to volcanic eruptions, respectively. The volcanic activity has clearly been a dominant contributor to the temperature variations in Northern Fennoscandia during the two last millennia.

We examine the annual, seasonal, monthly, and diurnal climate responses to the land use change (LUC) in eastern United States and Cuba during four epochs (1650, 1850, 1920, and 1992) with ensemble simulations conducted with the RegCM4 regional climate model that includes the Biosphere Atmosphere Transfer Scheme (BATS1e) surface physics package (Dickinson et al., 1993). We derived the land use (LU) data sets by harmonizing a previous reconstruction (Steyaert & Knox, 2008) with updated observations and modeled potential vegetation. The eight‐member ensembles for each epoch were driven with randomly perturbed 1990–2002 atmospheric boundary conditions derived from the National Center for Environmental Prediction global reanalysis. LUC induces statistically significant climate responses across all epochs; the largest changes occur between 1850 and 1920 with the widespread conversion of forests in the United States and forests, grassland, and woody wetlands in Cuba to agriculture. The atmospheric feedback from the aggregated grid‐cell responses attributed to physical and biophysical parameters in BATS1e alters the circulation in the lower atmosphere, thereby propagating the LUC regionally. Depending on the season and location, the altered circulation reinforces, attenuates, or has little effect on surface responses. Relative to pre‐settlement (1650), the 1992 LU produces colder mean annual air temperature (−0.09 ± 0.16 °C) and increased precipitation (0.08 ± 0.09 mm day−1) over the United States, warmer (0.08 °C) and wetter (0.03 mm day−1) conditions over Florida, and warming (0.32 °C) and drying (−0.03 mm day−1) over Cuba, indicating that LUC has played a varying role in climate change over the region.
