Labour share decline, financialisation and structural change
Authors: Pariboni Riccardo , Tridico Pasquale 
Published: April 2019

AbstractThe purpose of this article is to explain the determinants behind the decline of labour share in the last three to four decades in OECD countries. In our view, this decline was determined by financialisation and was deepened by the structural changes that occurred almost simultaneously in those economies. Financialisation, or finance-dominated capitalism, from the 1980s onwards, was a key element in the strategic offensive of the advanced countries’ dominant classes to appropriate higher shares of national income and to restore their control over the political process, a control that had been threatened by a generalised advancement of the labour movement in the 1970s. The development of a finance-dominated capitalism was helped by the process of globalisation, which affected not only OECD countries but also many others. A new, though unstable, macroeconomic model emerged, which we will call financial capitalism. In financial capitalism, trade unions lost power vis-à-vis capital, labour flexibility increased enormously, and a structural change from manufacturing to services was accelerated in rich countries. This resulted in negative consequences for labour share and income inequality. After having provided a theoretical discussion of the determinants of the compression of the wage share, making reference to the relevant literature, we submit our hypotheses to empirical scrutiny, performing a panel data analysis on 28 OECD Countries. The results of the estimations provide support to the theoretical argument.
A New Real-Time Link Prediction Method Based on User Community Changes in Online Social Networks

Published: April 2019

Abstract
The link prediction problem is becoming an important area of online social network (OSN) research. The existing methods that have been developed to address this problem mostly try to predict links based on structural information about the whole of the user lifespan. In addition, most of them do not consider user attributes such as user weight, density of interaction and geo-distance, all of which have an influence on the prediction of future links in OSNs due to the human-centric nature of these networks. Moreover, an OSN is a dynamic environment because users join and leave communities based on their interests over time. Therefore, it is necessary to predict links in real time. Therefore, the current study proposes a new method based on time and user attributes to predict links based on changes in user communities, where the changes in the user communities are indicative of users’ interests. The proposed method is tested on the UKM dataset and its performance is compared with that of 10 well-known methods and another community-based method. The area-under-the-curve results show that the proposed method is more accurate than all of the compared methods.

Authors: Huanca Ghislanzoni Luis , Ameur Sofian , Antonarakis Gregory S , Kiliaridis Stavros 
Published: April 2019

Summary

Objective
To accurately describe compliance in headgear wearing time by using a temperature- and force-sensitive device over an 8 month period of use in a prospective clinical manner.

Materials and methods
Twenty children with Class II malocclusion aged 8–12 years were randomly selected for treatment with cervical headgear. The headgears were equipped with an electronic module, which measured temperature and force, and patients were instructed to wear the headgear 12 hours daily. The recorded values were analysed to determine the number of days the headgear was used, the number of hours per day it was worn, and the percentage of compliance (100 per cent corresponding to 12 hours daily).

Results
The average treatment period was 8.4 months with 5.8 months of effective use. When effectively used, headgear was worn 8.7 hours a day (compliance of 73 per cent). Including days where it was not worn, compliance was 6.4 hours (54 per cent). The appliance was used on average 0.5 hours during the day (8 am–8 pm) and 5.9 hours during the night (8 pm–8 am). Very low compliance was recorded during July and August.

Conclusion
The average compliance with cervical headgear use was 54 per cent of the 12 hour prescription. The headgear was effectively used only 5.8 months over the study period, with roughly 30 per cent of no use. Headgear was used almost exclusively during evening and night-time. During the summer period, compliance was particularly poor.
Free-living amoebae and squatters in the wild: ecological and molecular features
Authors: Samba-Louaka Ascel , Delafont Vincent , Rodier Marie-Hélène , Cateau Estelle , Héchard Yann 
Published: April 2019

ABSTRACT
Free-living amoebae are protists frequently found in water and soils. They feed on other microorganisms, mainly bacteria, and digest them through phagocytosis. It is accepted that these amoebae play an important role in the microbial ecology of these environments. There is a renewed interest for the free-living amoebae since the discovery of pathogenic bacteria that can resist phagocytosis and of giant viruses, underlying that amoebae might play a role in the evolution of other microorganisms, including several human pathogens. Recent advances, using molecular methods, allow to bring together new information about free-living amoebae. This review aims to provide a comprehensive overview of the newly gathered insights into (1) the free-living amoeba diversity, assessed with molecular tools, (2) the gene functions described to decipher the biology of the amoebae and (3) their interactions with other microorganisms in the environment.

ABSTRACT

STUDY QUESTION
What were the risks with regard to the pregnancy outcomes of patients who conceived by frozen-thawed embryo transfer (FET) during a hormone replacement cycle (HRC-FET)?

SUMMARY ANSWER
The patients who conceived by HRC-FET had increased risks of hypertensive disorders of pregnancy (HDP) and placenta accreta and a reduced risk of gestational diabetes mellitus (GDM) in comparison to those who conceived by FET during a natural ovulatory cycle (NC-FET).

WHAT IS KNOWN ALREADY
Previous studies have shown that pregnancy and live-birth rates after HRC-FET and NC-FET are comparable. Little has been clarified regarding the association between endometrium preparation and other pregnancy outcomes.

STUDY DESIGN, SIZE, DURATION
A retrospective cohort study of patients who conceived after HRC-FET and those who conceived after NC-FET was performed based on the Japanese assisted reproductive technology registry in 2014.

PARTICIPANTS/MATERIALS, SETTING, METHODS
The pregnancy outcomes were compared between NC-FET (n = 29 760) and HRC-FET (n = 75 474) cycles. Multiple logistic regression analyses were performed to investigate the potential confounding factors.

MAIN RESULTS AND THE ROLE OF CHANCE
The pregnancy rate (32.1% vs 36.1%) and the live birth rate among pregnancies (67.1% vs 71.9%) in HRC-FET cycles were significantly lower than those in NC-FET cycles. A multiple logistic regression analysis showed that pregnancies after HRC-FET had increased odds of HDPs [adjusted odds ratio, 1.43; 95% confidence interval (CI), 1.14–1.80] and placenta accreta (adjusted odds ratio, 6.91; 95% CI, 2.87–16.66) and decreased odds for GDM (adjusted odds ratio, 0.52; 95% CI, 0.40–0.68) in comparison to pregnancies after NC-FET.

LIMITATIONS, REASONS FOR CAUTION
Our study was retrospective in nature, and some cases were excluded due to missing data. The implication of bias and residual confounding factors such as body mass index, alcohol consumption, and smoking habits should be considered in other observational studies.

WIDER IMPLICATIONS OF THE FINDINGS
Pregnancies following HRC-FET are associated with higher risks of HDPs and placenta accreta and a lower risk of GDM. The association between the endometrium preparation method and obstetrical complication merits further attention.

Energy assessment of the implementation of renewable energies in a Portuguese household
Authors: Palmero-Marrero Ana I , Pinheiro Ricardo , Oliveira Armando C 
Published: April 2019

Abstract
This paper presents a detailed energy analysis of a 37-year-old house, located near Porto, Portugal. The current situation leads to overheating in the Summer and low temperatures during the Winter, causing high levels of discomfort to the occupants. With the aim to improve the overall comfort, several passive/active solar systems were proposed, and a complete energetic analysis was made. The only air conditioning system used in the house is a wood-burning fireplace that distributes warm air through the rooms. During the Summer, no air conditioning is used. Throughout the year, comfortable conditions are not achieved for the occupants. Building energy requirements for the household in the cooling and heating seasons were quantified. The study was extended throughout a whole year: for the heating season and for the cooling season. Also, indoor temperatures were calculated through numerical simulations. The household and its components were modeled with the TRNSYS 17 program. The results show that the integration of passive and active solar systems, guarantee an improvement in comfort and energy savings. The amount of energy required by the household is covered, to a very significant extent (approximately 71%), by energy from renewable sources. The renewable sources considered were solar energy and biomass. As passive measures, a change of the windows and the increase in wall insulation were considered. For the solar active systems, the application of solar thermal collectors for Domestic Hot Water (DHW) and photovoltaic collectors for electricity generation at the household were analyzed. The consumption of biomass in the burning fireplace was also assessed.
War as Symbolic Politics
Authors: Kaufman Stuart J 
Published: April 2019

AbstractThis article uses Kaufman's symbolic politics theory of ethnic war as the basis for a broader theory integrating most existing insights about the causes of international and civil war. It starts with findings from psychology showing that people are intuitive thinkers whose decisions result less from rational calculation than from symbolic predispositions—biases such as ideology and prejudice. Studies also show that increased feelings of threat lead to increased aggressive attitudes and behavior. Symbolic politics theory explains how individual attitudes can result in collective action using mobilization theory, with social organization and framing by leaders explaining which attitudes become political action. According to symbolist logic, important causes of war include aggressive symbolic predispositions among leaders or mass publics, heightened threat perceptions, and strong political organizations backing aggressive leaders. Crises and enduring rivalries make war more likely because they strengthen hostile predispositions and threat perceptions, thereby promoting mobilization for war. Cooperative transnational ties and democratic political institutions are among the factors that tend to promote peace.

Abstract
The objective of this study was to determine the effects of increased AA and energy intake during late gestation on reproductive performance, milk composition, and metabolic and redox status of sows. A total of 118 Yorkshire sows (third through sixth parity) were randomly assigned to dietary treatments from day 90 of gestation until farrowing. Dietary treatments consisted of combinations of 2 standardized ileal digestible (SID) AA levels [14.7 or 20.6 g/d SID Lys, SID Lys and other AA met or exceeded the NRC (2012) recommendations] and 2 energy levels (28.24 or 33.78 MJ/d intake of NE) in a 2 × 2 factorial design. After parturition, all sows were fed a standard lactation diet. Blood samples were collected and analyzed for parameters on metabolism, redox status, and amino acid profile. The data were analyzed using the generalized linear mixed models to reveal the impact of dietary levels of energy, AA, and their interaction. Sows with increased intake of AA had greater BW gain (P < 0.01) during late gestation. Furthermore, the BW loss during lactation was increased in sows with increasing intake of energy (P < 0.05) or AA (P < 0.05). Sows fed high energy had higher total litter birth weights (20.2 kg vs. 18.4 kg, P < 0.05) and shorter duration of farrowing (261 min vs. 215 min, P < 0.05), compared with those fed low energy, which likely was due to higher (P < 0.05) plasma glucose and lower (P < 0.05) plasma lactate prior to parturition. High AA intake in late gestation increased the ADG of piglets during the following lactation (P < 0.05), and increased the concentrations of plasma urea, and the following AA: Lys, Met, Thr, Val, Ile, Leu, Phe, Asp, Ser, and Arg at farrowing (P < 0.05). In conclusion, the increased intake of energy increased total litter weight of newborns and shortened the farrowing duration, which likely was due to improved energy status at farrowing. Furthermore, sows with increased intake of AA led to higher growth rate of piglets during the following lactation, accompanying with the increasing levels of plasma urea and amino acids. Therefore, the higher energy intake in late gestation appeared to improve litter weight and farrowing duration, while higher AA intake may have positive effect on piglets performance in lactation.
Comparison of Different Trap Designs for Capture of Noctuid Moths (Lepidoptera: Noctuidae) With Pheromone and Floral Odor Attractants
Authors: Whitfield E Charles , Lobos Enrique , Cork Alan , Hall David R 
Published: April 2019

AbstractSix trap designs were assessed for capturing noctuid moths in field trials in the United Kingdom and Argentina. The traps were baited with either a sex pheromone for Autographa gamma in the UK trials and Helicoverpa gelotopoeon (Dyar) (Lepidoptera: Noctuidae) in Argentina, or a floral odor blend. In the UK trials the Universal Trap and a funnel sleeve trap were compared; in Argentina the funnel sleeve trap, a homemade bucket trap, and (L.) (Lepidoptera: Noctuidae) three sticky traps: LepTrap, wing trap, and delta trap were compared. Comparisons were made between the traps and attractants and captures of noctuid moths and nontarget insects. Traps baited with the floral attractant caught a lower number but a wider range of noctuid species including Helicoverpa, Spodoptera, Rachiplusia, Dargida, Mythimna, Chrysodeixis, Agrotis, and Autographa spp., and nontarget insects. In the UK trials, the funnel sleeve trap caught significantly more A. gamma than the Universal Trap. The addition of an insecticide to the Universal Trap marginally increased trap catches. In the Argentinian trials, the homemade bucket and the sleeve traps outperformed all sticky traps in most situations regardless of crop environment and attractant type. The homemade bucket and the funnel sleeve traps are also considerably cheaper than the other trap designs. Of the sticky traps the LepTrap caught more noctuids than the wing and delta traps. The results suggest that the bucket trap and the sleeve trap have a much greater maximum capacity and possibly a greater retention efficiency for noctuid moths compared to the sticky traps.
‘If We Hadn’t Left … We Would Have All Died’: Escaping Famine on the Greek Island of Chios, 1941–44
Authors: Hionidou Violetta 
Published: April 2019

AbstractThe decision-making processes of historical famine-induced migration movements have rarely been examined in detail. This article discusses such a movement from the Greek island of Chios and into Turkey in the early 1940s using first-hand accounts of famine survivors collected in the period 1999–2009. This article outlines the unfolding famine situation, describes the point at which individuals made the decision to leave or to stay and examines how that decision was implemented. The decision-making involved an elaborate process where pros and cons were assessed, where the wishes of individual family members were taken into consideration and where the long-term wellbeing of the family unit was the most important factor in any decision made. Difficult decisions, some of which may today appear irrational, were made. The article argues that individuals, even in crises situations, demonstrate agency and plan their actions and future, albeit within the constraints of a given situation.
On the millimetre continuum flux–radius correlation of proto-planetary discs
Authors: Rosotti Giovanni P , Booth Richard A , Tazzari Marco , Clarke Cathie , Lodato Giuseppe , Testi Leonardo 
Published: April 2019

Abstract
A correlation between proto-planetary disc radii and sub-mm fluxes has been recently reported. In this letter, we show that the correlation is a sensitive probe of grain growth processes. Using models of grain growth and drift, we have shown in a companion paper that the observed disc radii trace where the dust grains are large enough to have a significant sub-mm opacity. We show that the observed correlation emerges naturally if the maximum grain size is set by radial drift, implying relatively low values of the viscous α parameter ≲0.001. In this case, the relation has an almost universal normalization, while if the grain size is set by fragmentation the flux at a given radius depends on the dust-to-gas ratio. We highlight two observational consequences of the fact that radial drift limits the grain size. The first is that the dust masses measured from the sub-mm could be overestimated by a factor of a few. The second is that the correlation should be present also at longer wavelengths (e.g. 3mm), with a normalization factor that scales as the square of the observing frequency as in the optically thick case.

Abstract
RNA has become one of the major research topics in molecular biology. As a central player in key processes regulating gene expression, RNA is in the focus of many efforts to decipher the pathways that govern the transition of genetic information to a fully functional cell. As more and more researchers join this endeavour, there is a rapidly growing demand for comprehensive collections of tools that cover the diverse layers of RNA-related research. However, increasing amounts of data, from diverse types of experiments, addressing different aspects of biological questions need to be consolidated and integrated into a single framework. Only then is it possible to connect findings from e.g. RNA-Seq experiments and methods for e.g. target predictions. To address these needs, we present the RNA Workbench 2.0 , an updated online resource for RNA related analysis. With the RNA Workbench we created a comprehensive set of analysis tools and workflows that enables researchers to analyze their data without the need for sophisticated command-line skills. This update takes the established framework to the next level, providing not only a containerized infrastructure for analysis, but also a ready-to-use platform for hands-on training, analysis, data exploration, and visualization. The new framework is available at https://rna.usegalaxy.eu , and login is free and open to all users. The containerized version can be found at https://github.com/bgruening/galaxy-rna-workbench.
INGA 2.0: improving protein function prediction for the dark proteome
Authors: Piovesan Damiano , Tosatto Silvio C E 
Published: April 2019

AbstractOur current knowledge of complex biological systems is stored in a computable form through the Gene Ontology (GO) which provides a comprehensive description of genes function. Prediction of GO terms from the sequence remains, however, a challenging task, which is particularly critical for novel genomes. Here we present INGA 2.0, a new version of the INGA software for protein function prediction. INGA exploits homology, domain architecture, interaction networks and information from the ‘dark proteome’, like transmembrane and intrinsically disordered regions, to generate a consensus prediction. INGA was ranked in the top ten methods on both CAFA2 and CAFA3 blind tests. The new algorithm can process entire genomes in a few hours or even less when additional input files are provided. The new interface provides a better user experience by integrating filters and widgets to explore the graph structure of the predicted terms. The INGA web server, databases and benchmarking are available from URL: https://inga.bio.unipd.it/.
Big Three Dragons: A z = 7.15 Lyman-break galaxy detected in [O iii] 88 μm, [C ii] 158 μm, and dust continuum with ALMA

Abstract
We present new ALMA observations and physical properties of a Lyman break galaxy at z = 7.15. Our target, B14-65666, has a bright ultra-violet (UV) absolute magnitude, MUV ≈ −22.4, and has been spectroscopically identified in Lyα with a small rest-frame equivalent width of ≈4 Å. A previous Hubble Space TElescope (HST) image has shown that the target is composed of two spatially separated clumps in the rest-frame UV. With ALMA, we have newly detected spatially resolved [O iii] 88 μm, [C ii] 158 μm, and their underlying dust continuum emission. In the whole system of B14-65666, the [O iii] and [C ii] lines have consistent redshifts of 7.1520 ± 0.0003, and the [O iii] luminosity, (34.4 ± 4.1) × 108 L⊙, is about three times higher than the [C ii] luminosity, (11.0 ± 1.4) × 108 L⊙. With our two continuum flux densities, the dust temperature is constrained to be Td ≈ 50–60 K under the assumption of a dust emissivity index of βd = 2.0–1.5, leading to a large total infrared luminosity of LTIR ≈ 1 × 1012 L⊙. Owing to our high spatial resolution data, we show that the [O iii] and [C ii] emission can be spatially decomposed into two clumps associated with the two rest-frame UV clumps whose spectra are kinematically separated by ≈200 km s−1. We also find these two clumps have comparable UV, infrared, [O iii], and [C ii] luminosities. Based on these results, we argue that B14-65666 is a starburst galaxy induced by a major merger. The merger interpretation is also supported by the large specific star formation rate (defined as the star formation rate per unit stellar mass), sSFR $= 260^{+119}_{-57}\:$Gyr−1, inferred from our SED fitting. Probably, a strong UV radiation field caused by intense star formation contributes to its high dust temperature and the [O iii]-to-[C ii] luminosity ratio.
