Urbanization does not affect green space bird species richness in a mid-sized city

Published: December 2020

AbstractUrbanization is one of the most intensive forms of landscape and habitat transformation, resulting in species loss, and taxonomic and functional homogenization of different communities. Whilst green infrastructure (the network of natural and semi-natural areas in cities) has been studied extensively in terms of specific features that promote biodiversity, there have been no studies that have assessed how species richness in different types of green space (GS) varies with increasing levels of urbanization in the surrounding matrix. We studied the effects of different types of GS and urbanization in the surrounding matrix on bird communities in the mid-sized city of Göttingen, Germany. We used the point-count method for bird observations in allotments and parks. To determine the level of urbanization, we calculated percentage of impervious surfaces around GSs. Increasing levels of urbanization around GSs had no effect on the species richness, functional traits or the community composition of birds. Nevertheless, we found that species richness and functional traits varied according to GS type. Parks had a greater species richness and were found to have more ground nesting and tropical migrant birds compared to allotments. We found more cavity nesting and resident birds in allotments. As different types of GS can contribute to the presence of different species and functional trait variations, their positive effect on bird species richness can be enhanced when they are present together in urban landscapes. Our findings suggest that green spaces with a high variety of local characteristics should be incorporated into urban planning designs in order to ensure diverse bird communities in cities.

Published: December 2020

AbstractCellular senescence is a molecular hallmark of ageing that is associated with multiple pathologies, and DNA damage marker γH2AX, together with cell cycle inhibitor p21, have been used as senescence markers in multiple species including dogs. Idiopathic canine chronic hepatitis has recognised breed-related differences in predisposition and prognosis, but reasons behind this are poorly understood. This retrospective study using archived post mortem tissue aimed to provide insight into liver ageing in 51 microscopically normal canine livers across seven breed categories, including those with and without increased risk of chronic hepatitis. Immunohistochemistry was conducted for γH2AX, p21, and cell proliferation marker Ki67, and the mean number of positive hepatocytes per high power field was determined. All three markers were strongly correlated to each other, but no age-dependent expression was seen in the combined study population. Overall expression levels were low in most dogs, with median values representing less than 1.5% of hepatocytes, but this increased to 20–30% in individual dogs at the upper end of the range. Individual breed differences were noted in two breeds that have increased risk of chronic hepatitis, with English Springer Spaniels having lower expression of Ki67 than other dogs, and Labradors having higher expression of Ki67 and γH2AX than other dogs. These results warrant further investigation in these breeds and highlight a need to validate reliable markers of cellular senescence in dogs.
Dynamic Equilibrium of Market Making with Price Competition
Authors: Luo Jialiang , Zheng Harry 
Published: December 2020

AbstractIn this paper, we discuss the dynamic equilibrium of market making with price competition and incomplete information. The arrival of market sell/buy orders follows a pure jump process with intensity depending on bid/ask spreads among market makers and having a looping countermonotonic structure. We solve the problem with the nonzero-sum stochastic differential game approach and characterize the equilibrium value function with a coupled system of Hamilton–Jacobi nonlinear ordinary differential equations. We prove, do not assume a priori, that the generalized Issac’s condition is satisfied, which ensures the existence and uniqueness of Nash equilibrium. We also perform some numerical tests that show our model produces tighter bid/ask spreads than those derived using a benchmark model without price competition, which indicates the market liquidity would be enhanced in the presence of price competition of market makers.
Techno-economic modeling of an integrated biomethane-biomethanol production process via biomass gasification, electrolysis, biomethanation, and catalytic methanol synthesis
Authors: Menin Lorenzo , Benedetti Vittoria , Patuzzi Francesco , Baratieri Marco 
Published: December 2020

AbstractBiological methanation (biomethanation) of syngas obtained from biomass gasification offers the opportunity to employ a low-pressure, low-temperature process to produce storable bio-derived substitute natural gas (bSNG), although its economic viability is limited by high energy and biomass costs. Research on syngas biomethanation techno-economic performance is limited and novel biomass-to-biomethane process configurations are required in order to assess opportunities for the enhancement of its efficiency and economic feasibility. In this study, we carried out the techno-economic modeling of two processes comprising integrated biomass gasification, electrolysis, and syngas biomethanation with combined heat and power recovery in order to assess and compare their fuel yields, energy efficiency, carbon efficiency, and bSNG minimum selling price (MSP). The first process operates standalone biomethanation (SAB) of syngas and can produce approximately 38,000 Nm3of bSNG per day, with a total plant efficiency of 50.6%. The second process (integrated biomethane-biomethanol, IBB) exploits the unconverted carbon stream from the biomethanation process to recover energy and synthesize methanol via direct catalytic CO2hydrogenation. In addition to the same bSNG output, the IBB process can produce 10 t/day of biomethanol, at a 99% purity. The IBB process shows little global energy efficiency gains in comparison with SAB (51.7%) due to the large increase in electrolytic hydrogen demand, but it shows a substantial improvement in biomass-to-fuel carbon efficiency (33 vs. 26%). The SAB and IBB processes generate a bSNG MSP of 2.38 €/Nm3and 3.68 €/Nm3, respectively. Hydrogenation of unconverted carbon in biomass-to-biomethane processes comes with high additional capital and operating costs due to the large-scale electrolysis plants required. Consequently, in both processes, the market price gap of the bSNG produced is 0.13 €/kWhbSNG(SAB) and 0.25 €/kWhbSNG(IBB) even under the most optimistic cost scenarios considered, and it is primarily influenced by the cost of surplus electricity utilized in electrolysis, while the selling price of biomethanol exerts a very limited influence on process economics. Intensive subsidization would be required in order to sustain the decentralized production of bSNG through both processes. Despite their limited economic competitiveness, both processes have a size comparable with existing renewable gas production plants in terms of bSNG production capacity and the IBB process is of a size adequate for the supply of biomethanol to a decentralized biorenewable supply chain.
Highest Harm Crime “Recruiters” in a London Borough: a Case of Moving Targets
Authors: Linton Benedict , Ariel Barak 
Published: December 2020

Abstract
Research Question
Can criminal recruiters be identified and ranked by crime harm levels in a London borough, and if so, how long is the predictive window of opportunity for targeting them with crime prevention efforts?

Data
This study deploys 5 years of Metropolitan Police Service crime data, relating to one of the 32 London boroughs in that time period. The data structure allowed identification of all suspects linked to the same crime report and all crime reports linked to the same suspects. Identification of linked suspects and their associated crime harm was undertaken using Structured Query Language (SQL) and ColdFusion Markup Language (CFML) via a web-based application.

Methods
All offenders were ranked by the number of co-offenders they acquired, as well as the total Cambridge crime harm index weight of the detected offences associated with them.

Findings
The highest harm recruiters are shown to be up to 137 times as harmful as the average offender, with one recruiter committing the same number of crimes as another but having 97 times more crime harm. Recruiter populations are highly dynamic, with few potential targets persisting from year to year over multiple years.

Conclusions
This study suggests that criminal recruiters are readily identifiable from police data, but police would only have a short window of opportunity to use deterrent or other preventive strategies with them once they are identified.
SES differences in marital fertility widened during the fertility transition—evidence from global micro-level population data
Authors: Dribe Martin , Scalone Francesco 
Published: December 2020

AbstractThe decline in human fertility during the demographic transition is one of the most profound changes to human living conditions. To gain a better understanding of this transition we investigate the association between socioeconomic status (SES) and marital fertility in different fertility regimes in a global and historical perspective. We use data for a large number women in 91 different countries for the period 1703–2018 (N = 116,612,473). In the pre-transitional fertility regime the highest SES group had somewhat lower marital fertility than other groups both in terms of children ever born (CEB) and number of surviving children under 5 (CWR). Over the course of the fertility transition, as measured by the different fertility regimes, these rather small initial SES differentials in marital fertility widened, both for CEB and CWR. There was no indication of a convergence in marital fertility by SES in the later stages of the transition. Our results imply a universally negative association between SES and marital fertility and that the fertility differentials widened during the fertility transition.
The policy-seeking voter: evaluations of government performance beyond the economy
Authors: Markwat Niels 
Published: December 2020

AbstractVoters hold governments to account through elections, but which criteria are most important to voter evaluations of incumbent performance? While (economic) outcomes have long been central to studies of retrospective voting, recent studies have considered the influence of policy output—the policies implemented by incumbents to achieve their goals. Building on this promising development, this study identifies three ways in which policy output is expected to affect voter evaluations of incumbent performance—the congruence between implemented policy and (1) individual preferences; (2) public opinion; and (3) election pledges. A discrete choice experiment was designed to assess the relative importance of these three aspects of policy output in comparison to each other; as well as to two important economic indicators. Overall, the findings support the notion that policy output matters to voters even beyond outcomes. The findings also show that voters value congruence between policy and their personal preferences considerably more than policy congruence with public opinion; and election pledge fulfillment. This indicates that voters are egotropic in their evaluation of implemented policy, and more policy-seeking than accounted for in much of the empirical retrospective voting literature. These results inform our understanding of how policy output matters to voters, as well as of how voters hold governments accountable for their performance.
A non-iterative design for aileron to rudder interconnect gain
Authors: Myala J. , Patel V.V. , Singh G.K. 
Published: December 2020

AbstractAileron to Rudder Interconnect (ARI) gain is implemented on most fighter aircraft, primarily to reduce the side slip produced due to adverse yaw from pilot lateral control stick input and to improve the turn rate response. A systematic and non-iterative design procedure for ARI gain is proposed herein based on the evaluation of a transfer function magnitude at the aircraft roll mode frequency. The simplicity of the proposed method makes it useful for real-time flight control law reconfiguration in situations where the aileron control authority is diminished due to damage. This is demonstrated by a simulation example considering an aileron surface damage scenario.
Cherchez la femme?Fadia in Plutarch'sLife of Antony
Authors: Tatum W. Jeffrey 
Published: December 2020

AbstractIn hisPhilippicsCicero more than once refers to Fadia, whom he depicts as Antony's wife, and to the children she bore him. He also discusses Fadia in his correspondence with Atticus. Plutarch was aware of thePhilippicsand much of Cicero's correspondence, and therefore of Fadia, and yet, in hisLife of Antony, he says nothing about her. This paper examines three possible explanations for the biographer's silence: (i) an informed sensibility regarding the historical value of invective; (ii) the narrative design of thisLifeand its contribution to Plutarch's characterisation of Antony; (iii) Plutarch's (disturbing by contemporary standards) disapproval of an aristocrat's siring children on women of the lower orders – even by way of legitimate marriage or concubinage. It is, it appears, the ensemble of these factors which excludes Fadia from Plutarch's biography, and the pertinence of each adds to our appreciation of Plutarch's biographical principles.
Patronage, Poetic Lineage, and Wordplay: A New Dedicatory Acronym in Vergil's SixthEclogue
Authors: Bernstein Frances M. 
Published: December 2020

AbstractThis article identifies and defends a previously unobserved dedicatory acronym to Maecenas in the second half ofEcl. 6.69 (MAEC- in reverse:Calamos,EnAccipe,Musae) and contextualizes the specific linguistic choices and central themes of that acronym within a broader network of Vergilian word games. I argue that the dedicatory acronym inEcl.6.69 shares linguistic and thematic features with numerous previously identified Vergilian word games, and that from this network of wordplay emerges a common discourse on poetic lineage, genre, and patronage. An awareness of this network of wordplay in Vergil's corpus provides a starting point for a more comprehensive and nuanced interpretation both of individual Vergilian word games and of Vergilian wordplay as a general phenomenon. On a literary level, the conclusions I draw from theMAEC- acronym and the relationship between wordplay and various thematic issues inform a clearer picture of generic shifts and expectations inEclogue6, theEcloguesin general, and Vergil's corpus more broadly, and contribute to an understanding of the subtle ways in which Vergil negotiates issues of patronage in his first collection.
A HIGH-RESOLUTION CHRONOLOGY FOR THE PALATIAL COMPLEX OF XALLA IN TEOTIHUACAN, MEXICO, COMBINING RADIOCARBON AGES AND ARCHAEOMAGNETIC DATES IN A BAYESIAN MODEL

Published: December 2020

ABSTRACTTeotihuacan is one of the most studied archaeological sites in Mesoamerica because of its exceptional size and urban planning; however, its last years of occupation and abandonment are still under debate. We report a high-resolution chronology for the Xalla complex integrating archaeomagnetic dates, radiocarbon (14C) ages, and detailed archaeological information about sample type and context in a Bayesian model. The model includes 42 14C ages and 7 archaeomagnetic dates grouped in 6 phases, including samples from collapsed roofs with 14C ages earlier than expected, suggesting a problem of inbuilt age. The archaeomagnetic dates on lime plasters were classified in unburned samples, related to the time of construction, and burned samples, related to the Big Fire associated to the abandonment of Teotihuacan. The modeled 14C ages resulted in shorter intervals, with the possibility of differentiating the construction phases, confirming that big beams had inbuilt age. Further, combining the two dating methods and classifying lime plaster samples in burned and unburned, it was possible to date different events within the same archaeological context. It is concluded that by combining these two dating methods and understanding the moment that each sample is dating, it is possible to obtain solid and precise chronologies.
Effect of a moderate dose of fructose in solid foods on TAG, glucose and uric acid before and after a 1-month moderate sugar-feeding period
Authors: Clifton Peter M. , Keogh Jennifer B. 
Published: December 2020

AbstractThere are few data on the effects on TAG, glucose and uric acid of chronic consumption of a moderate dose of fructose in solid foods. Twenty-eight participants with prediabetes and/or obesity and overweight commenced the study (BMI 32·3 kg/m2, age 44·7 years, fasting glucose 5·3 (sd 0·89) mmol/l and 2-h glucose 6·6 (sd 1·8) mmol/l). Twenty-four men and women who completed the study consumed, in random order, two acute test meals of muffins sweetened with either fructose or sucrose. This was followed by 4-week chronic consumption of 42 g/d of either fructose or sucrose in low-fat muffins after which the two meal tests were repeated. The sugar type in the chronic feeding period was also randomised. Fasting TAG increased after chronic consumption of fructose by 0·31 (sd 0·37) mmol/l compared with sucrose in those participants with impaired fasting glucose (IFG)/impaired glucose tolerance (IGT) (P = 0·004). Total cholesterol (0·33 mmol/l), LDL-cholesterol (0·24 mmol/l) and HDL-cholesterol (0·08 mmol/l) increased significantly over the 1- month feeding period with no differences between muffin types. Fasting glucose was not different after 1 month of muffin consumption. Uric acid response was not different between the two sugar types either baseline or 1 month, and there were no differences between baseline and 1 month. The increase in fasting TAG in participants with IFG/IGT suggests the need for caution in people at increased risk of type 2 diabetes.

AbstractThis randomised clinical trial aimed to evaluate the effect of a pro-breast-feeding (BF) and healthy complementary feeding intervention performed during infants’ first months of life on ultraprocessed food (UPF) consumption at 4–7 years. We enrolled 323 teenage mothers and their infants from South Brazil, 163 allocated to the intervention group and 160 to the control group. Intervention consisted of sessions on BF and healthy complementary feeding promotion and was carried out in the maternity ward and at home after delivery. Food consumption was assessed using three 24-h food recalls at child’s age of 4–7 years. Foods were classified according to NOVA classification. Dietary contribution of UPF was adjusted for intra-individual variability by the SPADE method and categorised into tertiles. We used Poisson regression models with robust variance, adjusted for confounders, to estimate the effect of the intervention and duration of BF on the risk of high consumption of UPF. Our final analysis included 194 children, with mean age of 6·1 (sd 0·5) years. Mean dietary contribution of UPF was 38 % in the intervention group and 42·7 % in the control group, from total daily intakes. Results adjusted for BF duration, propensity score, income and total energy content demonstrated that the intervention reduced the risk of high consumption of UPF by 35 % (relative risk 0·65, 95 % CI 0·43, 0·98). BF duration was not associated with UPF consumption. The intervention was effective in reducing the risk of high UPF consumption at the age of 4–7 years.

Published: December 2020

AbstractIncreasing crop diversity has been highly recommended because of its environmental and economic benefits. However, the impacts of crop diversity on soil properties are not well documented. Thus, the present study was conducted to assess the impacts of crop diversity on selected soil quality indicators. The cropping systems investigated here included wheat (Triticum aestivumL.) grown continuously for 5 years as mono-cropping (MC), and a 5-year cropping sequence [(wheat–cover crop (CC)–corn (Zea maysL.)–pea (Pisum sativumL.) and barley (Hordeum vulgareL.)–sunflower (Helianthus annuus L.)]. Each crop was present every year. This study was conducted in the northern Great Plains of North America, and soil quality data were collected for 2016 and 2017. Selected soil quality indicators that include: soil pH, organic carbon (SOC), cold water-extractable C (CWC) and N (CWN), hot water-extractable C (HWC) and N (HWN), microbial biomass carbon (MBC), bulk density (BD), water retention (SWR), wet soil aggregate stability (WAS), and urease andβ-glucoside enzyme activity were measured after the completion of 5-year rotation cycle and the following year. Crop diversity did not affect soil pH, CWC, CWN, HWC, HWN and SWR. Cropping systems that contained CC increased SOC at shallow depths compared to the systems that did not have CC. Crop diversity increased WAS, MBC, and urease andβ-glucoside enzyme activity compared with the MC. Comparison of electrical conductivity (EC) measured in this study to the baseline values at the research site prior to the establishment of treatments revealed that crop rotation decreased EC over time. Results indicate that crop diversity can improve soil quality, thus promoting sustainable agriculture.
