Twins Support the Absence of Parity-Dependent Fertility Control in Pretransition Populations
Authors: Clark Gregory , Cummins Neil , Curtis Matthew 
Published: July 2020

Abstract
A conclusion of the European Fertility Project in 1986 was that pretransition populations mostly displayed natural fertility, where parity-dependent birth control was absent. This conclusion has recently been challenged for England by new empirical results and has also been widely rejected by theorists of long-run economic growth, where pre-industrial fertility control is integral to most models. In this study, we use the accident of twin births to show that for three Western European–derived pre-industrial populations—namely, England (1730–1879), France (1670–1788), and Québec (1621–1835)—we find no evidence for parity-dependent control of marital fertility. If a twin was born in any of these populations, family size increased by 1 compared with families with a singleton birth at the same parity and mother age, with no reduction of subsequent fertility. Numbers of children surviving to age 14 also increased. Twin births also show no differential effect on fertility when they occurred at high parities; this finding is in contrast to populations where fertility is known to have been controlled by at least some families, such as in England, 1900–1949, where a twin birth increased average births per family by significantly less than 1.
A fragile and divided European Union meets Covid-19: further disintegration or ‘Hamiltonian moment’?
Authors: Celi Giuseppe , Guarascio Dario , Simonazzi Annamaria 
Published: July 2020

AbstractDespite being symmetric in its very nature, the Covid-19 shock is affecting European economies in a very asymmetric way, threatening to deepen the divide between core and peripheral countries even more. It is not Covid-19 itself, however, but the contradictions within the EU’s growth model and institutional architecture that would be to blame for such an outcome. The dramatic impact of the economic crisis brought on by the pandemic and the threat that it poses to Eurozone survival seem to have forced a reluctant Germany into action: a minor step, but an important signal. This note analyses the crossroads currently facing Europe—the risk of disintegration vis-a-vis the opportunity for a ‘Hamiltonian moment’—discussing possible future scenarios in the light of past developments.
Predicting SARS-CoV-2 Infection Trend Using Technical Analysis Indicators
Authors: Paroli Marino , Sirinian Maria Isabella 
Published: July 2020

ABSTRACTObjectives:Coronavirus disease 2019 (COVID-19) pandemic is a global health emergency caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study aimed to evaluate whether technical analysis (TA) indicators, commonly used in the financial market to spot security price trend reversals, might be proficiently used also to anticipate a possible increase of SARS-Cov-2 spread.Methods:Analysis was performed on datasets from Italy, Iran, and Brazil. TA indicators tested were: (1) the combined use of a faster (3-d) and a slower (20-d) simple moving averages (SMA), (2) the moving average converge/divergence (MACD), and (3) the divergence in the direction of the number of new daily cases trend and the corresponding MACD histogram.Results:We found that the use of both fast/slow SMAs and MACD provided a reliable signal of trend inversion of SARS-Cov-2 spread. Results were consistent for all the 3 countries considered. The trend reversals signaled by the indicators were always followed by a sustained trend persistence until a new signal of reversal appeared.Conclusions:TA indicators tested here proved to be reliable tools to identify in the short mid-term a subsequent change of direction of viral spread trend either downward, upward, or sideward.
Europe matters … upon closer investigation: a novel approach for analysing individual-level determinants of vote choice across first- and second-order elections, applied to 2019 Italy

Published: July 2020

AbstractAre European Parliament (EP) elections still second-order? In this article, we test the classical model at the individual level in contrast to an alternative ‘Europe matters’ model, by investigating the relative importance of domestic vs. European Union (EU)-related issues among voter-level determinants of aggregate second-order effects, that is, individual party change. We do so by relying on an original, CAWI pre-electoral survey featuring a distinctively large (30) number of both domestic and EU-related, positional and valence issues, with issue attitudes measured according to the innovative ICCP scheme (De Sio and Lachat 2020) which includes issue positions, issue priorities and respondents' assessment of party credibility on both positional and valence goals. Leveraging the concept of ‘normal vote’, we estimate multivariate models of electoral defections from normal voting separately for general and European elections, based on issue party credibility. This allows us to assess: (a) the distinctiveness of the two electoral arenas in terms of issue content; and (b) the relative impact of EU-related and domestic issues on defections of Italian voters. Our findings show that although second-order effects are still relevant in accounting for results in EP elections, vote choice in the latter is also partly due to specific effects of certain policy issues, including some related to the European dimension. This indicates that EP elections have their own political content, for which Europe matters even after controlling for the importance that EU-related issues have acquired in national elections.

AbstractMexican beetle, Zygogramma bicolorata Pallister (Coleptera: Chrysomelidae) is a potential weed control biocontrol agent in Australia, India and other countries. Its grubs and adults feed on the leaves of parthenium weed, Parthenium hysterophorus and check the further growth of the plant. Experiments were conducted to understand host plant-mediated effects of elevated temperature and elevated CO2 on biocontrol agent Z. bicolorata. Food consumption, utilization, ecological efficiency and life-table parameters of Z. bicolorata were studied in grubs and adults stage up to diapause. Reduction of leaf nitrogen in parthenium weed foliage with a significant increase in carbon and C:N ratio was recorded at elevated CO2. Elevated CO2 and temperature had no effect on adult longevity before diapausing. Duration of egg's hatching, specific stages of grub and pupa of Z. bicolorata were significantly longer when beetles fed on leaves grown under elevated CO2 but these parameters decreased significantly on leaves grown under elevated temperature. Significantly high consumption rates with low growth and digestion conversions were observed under elevated CO2 and/or in coupled with elevated temperature. Elevated CO2 and temperature-grown parthenium weed foliage also had a significant effect on Z. bicolorata intrinsic rate of increase (R), finite rate of increase (λ), mean generation time (T), and gross reproductive rate. Changed quality of parthenium weed leaves in elevated CO2 and temperature levels resulted in the increase of consumption, slower food conversion rates, increase in developmental period with reduced reproduction efficiency of Z. bicolorata. Our results indicate that the reproduction efficiency of Z. bicolorata is likely to be reduced as the climate changes, despite increased feeding rates exhibited by grubs and adult beetles on parthenium weed foliage.

AbstractOwing to its contribution to the maintenance of carbon stocks, soil nitrogen and nutrient cycling for subsequent crops, the integrated systems become increasingly important for agricultural conservation. Thus, the objective of this study was to evaluate the biomass production of and total nutrient in Brachiaria spp. and Panicum maximum forage grasses used as mulch and soybean yields in an integrated crop–livestock system and second-crop maize succession system. The treatments consisted of the following cropping systems: Xaraes palisadegrass intercropped with soybean, Congo grass intercropped with soybean, Mombaça guinea grass intercropped with soybean, Tamani guinea grass intercropped with soybean and a soybean/maize succession system. The forage grasses were established during the soybean R6–R7 stage. Compared with Congo grass, Xaraes palisadegrass, Mombaça guinea grass and Tamani guinea grass produced more biomass and equivalent amounts of fertilizer returned to the soil and resulted in greater nutrient cycling, indicating the benefits of these grasses for use as mulch in integrated production systems. Maize had a greater C/N ratio, but the forage grasses also exhibited high potential by protecting the soil until the end of the soybean development cycle. The use of an integrated crop–livestock system combined with a forage cropping system provided greater soil nutrient cycling than the maize cropping system did, which resulted in increased soybean yields, thus contributing to the sustainability of agricultural systems.

AbstractBackgroundInvasive fungal rhinosinusitis is associated with high morbidity and mortality. Rapid pathogen identification is mandatory, but fresh tissue is not always available. A polymerase chain reaction method was designed in order to detect fungi in formalin-fixed paraffin-embedded samples. This was applied to a retrospective series of tissue biopsies from Thai patients with invasive fungal rhinosinusitis.MethodsTissue blocks from 64 cases yielded adequate DNA. Three sequential polymerase chain reaction were performed: ZP3 (housekeeping gene) and panfungal polymerase chain reactions, and a differentiating polymerase chain reaction based on the 5.8s ribosomal RNA and internal transcribed spacer 2 regions. The polymerase chain reaction products were then sequenced.ResultsPolymerase chain reaction identified a fungal pathogen in 20 of 64 cases (31 per cent). Aspergillus species was the most common cause of invasive fungal rhinosinusitis (nine cases). Other causes included candida (n = 4), cladosporium (n = 4), mucor (n = 1), alternaria (n = 1) and dendryphiella (n = 1) species.ConclusionPolymerase chain reaction can provide rapid identification of fungal pathogens in paraffin-embedded tissue, enabling prompt treatment of invasive fungal rhinosinusitis.

AbstractBackgroundA large body of research states that cognitive impairment in schizophrenia is static. Nevertheless, most previous studies lack a control group or have small study samples or short follow-up periods.MethodWe aimed to address these limitations by studying a large epidemiological cohort of patients with first-episode schizophrenia spectrum disorders and a comparable control sample for a 10-year period.ResultsOur results support the generalized stability of cognitive functions in schizophrenia spectrum disorders considering the entire group. However, the existence of a subgroup of patients characterized by deteriorating cognition and worse long-term clinical outcomes must be noted. Nevertheless, it was not possible to identify concomitant factors or predictors of deterioration (all Ps > 0.05).ConclusionsCognitive functions in schizophrenia spectrum disorder are stable; however, a subgroup of subjects that deteriorate can be characterized.
Associations of physical and psychiatric conditions with chronic fatigue syndrome in Germany: an exploratory case-control study
Authors: Jacob Louis , Haro Josep Maria , Kostev Karel 
Published: July 2020

AbstractBackgroundOnly a few studies have analyzed the effects of physical and psychiatric conditions on the risk of chronic fatigue syndrome (CFS). Therefore, the goal of this exploratory case-control study was to investigate the associations of physical and psychiatric conditions with CFS in almost 19 800 adults from Germany.MethodsThis study included patients diagnosed for the first time with CFS in one of 1238 general practices in Germany between 2010 and 2017 (index date). Controls without CFS were matched (1:1) to cases with CFS by sex, age, index year, and practice. Physical and psychiatric conditions diagnosed in the year prior to the index date were included if they were present in at least 3% of patients with CFS. Associations between physical and psychiatric conditions (33 potential independent variables) and CFS (dependent variable) were analyzed in an adjusted conditional logistic regression model, and physical and psychiatric disorders were included in the model using forward stepwise selection.ResultsThis study included 9896 cases with CFS and 9896 controls without CFS [65.1% women; mean (standard deviation) age 49.5 (18.3) years]. Seven conditions were associated with CFS in the adjusted regression model. The disorders displaying the strongest relationship with CFS were cancer [odds ratio (OR) = 2.57, 95% confidence interval (CI) = 2.24–2.95], sleep disorders (OR = 1.88, 95% CI = 1.66–2.12) and depression (OR = 1.77, 95% CI = 1.61–1.95).ConclusionsCancer, sleep disorders, and depression were strongly and positively associated with CFS. Additional studies are needed to gain a better understanding of the mechanisms underlying these relationships.
The prosody of other-repetition in Italian: A system of tunes
Authors: Rossi Giovanni 
Published: July 2020

AbstractAs part of the project reported on in this special issue, the present study provides an overview of the types of action accomplished by other-repetition in Italian, with particular reference to the variety of the language spoken in the northeastern province of Trento. The analysis surveys actions within the domain of initiating repair, actions that extend beyond initiating repair, and actions that are alternative to initiating repair. Pitch contour emerges as a central design feature of other-repetition in Italian, with six nuclear contours associated with distinct types of action, sequential trajectories, and response patterns. The study also documents the interplay of pitch contour with other prosodic features (pitch span and register) and visible behavior (head nods, eyebrow movements).

Published: July 2020

SUMMARYOptimal grasping points for a robotic gripper were derived, based on object and hand geometry, using deep neural networks (DNNs). The optimal grasping cost functions were derived using probability density functions for each local cost function of the normal distribution. Using the DNN, the optimum height and width were set for the robot hand to grasp objects, whose geometric and mass centre points were also considered in obtaining the optimum grasping positions for the robot fingers and the object. The proposed algorithm was tested on 10 differently shaped objects and showed improved grip performance compared to conventional methods.
Transcatheter ablation using near-zero fluoroscopy in children with focal atrial tachycardia: a single-centre experience
Authors: Balli Sevket , Kucuk Mehmet 
Published: July 2020

AbstractObjective:Focal atrial tachycardia accounts for up to 10–15% of supraventricular tachycardiasubstrates in patients < 30 years. In this study, we aimed to demonstrate the outcome of transcatheter ablation procedures performed through three-dimensional electroanatomic mapping systems using minimal fluoroscopy in a paediatric cohort with focal atrial tachycardia.Methods:Forty-nine consecutive patients with focal atrial tachycardia who underwent an electrophysiologic study and a transcatheter ablation procedure in our hospital from September 2014 to February 2020 were included into the study.Results:The mean weight of the patients was 48.63 ± 15.4 kg, and the mean age was 14.56 ± 3.5 (5.5–18.4) years. The tachycardia was defined as incessant in 26 patients. Thirteen patients had left ventricular systolic dysfunction with a mean left ventricular ejection fraction of 38.47 ± 12.4% on echocardiography. The mean procedure time was 148.7 ± 94.5 minutes. Transseptal puncture and thus fluoroscopy were required in nine patients. The mean fluoroscopy time was 4.51 ± 5.9 minutes. No fluoroscopy was needed in ablations performed in the right atrium. The acute success rate of the ablation procedures was 97.9%. The mean follow-up period was 50.71 ± 23.5 months. Recurrence was noted in two patients (4.2%).Conclusion:The outcomes of three-dimensional electroanatomic mapping-guided transcatheter ablation procedures are promising with high acute success, low recurrence and complication rates in children with focal atrial tachycardia. The use of fluoroscopy can be significantly decreased with three-dimensional mapping systems in this group of patients.

AbstractEarly weaning can lead to changes in the morphology of organs in adulthood, and the consumption of functional foods during lactation and postnatal life is believed to prevent these changes. However, it is not known if early weaning affects testicular morphology and if the use of cocoa can prevent that. We studied the effects of maternal and postnatal supplementation of cocoa powder on the testicular morphology of early weaned adult rats. The animals were divided into four groups (n = 6 each), control group, cocoa control group, early weaning (EW) group, and cocoa early weaning (EWCa) group, and were analyzed for 90 d, after which they were euthanized. The animals from the EW group showed a reduction in the tubular diameter and height of the seminiferous epithelium, a decrease in epithelial surface density (Sv), and an increase in the lumen and proper tunic. However, the animals from the EWCa group showed an increase in the diameter and height of the epithelium, an increase in the epithelium Sv, and a decrease in the lumen and the proper tunic. The early weaning promotes morphological changes in the testicles; however, supplementation with cocoa powder can preserve the testicular histoarchitecture.
Human rights courts and global constitutionalism: Coordination through judicial dialogue
Authors: SANDHOLTZ WAYNE 
Published: July 2020

AbstractInternational courts regularly cite each other, partly as a means of building legitimacy. This study aims to show that judicial dialogue among the regional human rights courts and the Human Rights Committee has an additional effect: it contributes to the construction of a rights-based global constitutionalism. Judicial dialogue among the human rights courts is purposeful because the courts see themselves as embedded in, and contributing to, a global human rights legal system. Cross-citation among the human rights courts advances the construction of rights-based global constitutionalism in that it provides a basic degree of coordination among the regional courts. The jurisprudence of the United Nations Human Rights Committee (HRC), as an authoritative interpreter of core international human rights norms, plays the role of a central focal point for the decentralized coordination of jurisprudence. Using original data, this study demonstrates the extent of citations among the regional human rights courts and from them to the HRC. The network of regional courts and the HRC is building an emergent institutional structure for global rights-based constitutionalism.
Emotional Dissonance in the Spanish Services Sector: The Role of Support in the Workplace
Authors: Sora Beatriz , Vera María 
Published: July 2020

AbstractThe purpose of this study was twofold. The first aim was to analyze the detrimental effect that emotional dissonance may have on service workers by testing its relationship with job satisfaction, intention to leave the organization, and organizational deviance. The second was to test whether two types of social support (i.e., co-worker and organizational support) and their combination moderate these relationships from a multilevel perspective. The sample was composed of 556 employees from Spanish service sector. Using random coefficient models analyses, results showed, first, that emotional dissonance was related to lower levels of job satisfaction (PE =–.1,p <.05) and higher levels of intention to leave the organization (PE =.12,p <.05); second, that co-worker support moderate the relationship between emotional dissonance and job satisfaction (PE =.10,p <.05), organizational deviance (PE =–.08,p <.05), and intention to leave the organization (PE =–.13,p <.05); third, organizational support, conceptualized as a collective construct at organizational level, moderate the relationship between emotional dissonance and organizational deviance (PE= –.08,p< .05); and finally, the combination of both types of support do not explained additional variance of the emotional dissonance-outcomes relation. These results underline the need to take into consideration different source of social support and their levels of analysis to better understand emotional dissonance and its outcomes.
