The Basilica Ulpia, Early Christian Churches and the Roman Double Truss
Authors: Robison Elwin C. 
Published: November 2021

ABSTRACTThe most prominent and long-lasting of the timber truss-roofed buildings from imperial Roman times was the Basilica Ulpia, the interior of which has been reconstructed by recent writers but with little agreement regarding the upper sections. The reconstruction that best passes the test of engineering viability is shown here to be the one published by James E. Packer in 1997, but Packer’s reconstruction is unconvincing with regard to the roof. The argument advanced now is that the roof was constructed with double trusses of the kind once found in the early Christian basilicas of Old St Peter’s and San Paolo fuori le Mura, and then recorded in the eighteenth century by Jean-Baptiste Rondelet, which were very similar in size to those used for the Basilica Ulpia. The spacing of roof trusses was determined by the nave column spacing. Engineering analysis determines that the trusses had sufficient capacity to support the roof and that the double-truss arrangement was critical to avoid overloading the stone architraves. The article speculates that doubling the Roman truss may have been a previous innovation. It argues that the later early Christian basilicas relied on the Roman double truss because of its proven performance, and that this continuity was recognised by Auguste Choisy and others who considered their use to be a reflection of earlier Roman practice.

AbstractEristalinus aeneus(Scopoli, 1763) is a suitable candidate for artificial rearing due to its pollination efficiency and subcosmopolitan distribution. However, the high mortality found at the larval stage of this species needs to be overcome. In this research, two different larval media were used to study the life cycle ofE. aeneus: brewery spent grain (BSG) from a local craft-beer factory and soaked oat grains (SOG). The age-stage, two-sex life table method was used to analyze the results, which were compared using the paired bootstrap test. The greatest mortality was found at the larval stage with both media. Individuals fed on SOG presented a shorter preadult developmental time (22.05 days) than those reared with BSG (26.97 days). This fact had a direct impact on the total preoviposition period, it being shorter with SOG (34.36 days) than BSG (38.29 days), although the second provided a larger total number of eggs (19,242 eggs) and a faster adult maturation (10.67 days). The population parameters indicated that both populations will display a positive growth under the studied conditions, being the mean generation time (T) significantly shorter when using SOG (38.71 days) than BSG (45.95 days). Despite the preadult results pointing to SOG being a more efficient medium, the promising fecundity values provided by BSG, as well as it's lower cost and ecological benefits, suggest that this second medium could be improved and used as an alternative to SOG in the near future.
The influence of infection status and parasitism risk on host dispersal and susceptibility to infection inDrosophila nigrospiracula
Authors: Brophy Taylor , Luong Lien T. 
Published: November 2021

AbstractFor many organisms, habitat avoidance provides the first line of defence against parasitic infection. Changes in infection status can shift the cost-benefit ratio of remaining in a given habitatvsdispersing. The aim of this study was to test the hypothesis that the propensity to disperse inDrosophila nigrospiraculais mediated by current parasite load and the risk of further infection by an ectoparasitic mite (Macrocheles subbadius). An activity monitor was used to assess dispersal propensity among infected and uninfected flies. The activity level of uninfected females increased threefold upon exposure to a mite, whereas the activity among uninfected males increased by 17-fold in the presence of a questing mite. Among infected flies, the risk of further infection also generated a change in activity, but the magnitude of the response was dependent on host sex. Current infection status influenced the probability of acquiring more parasites due to increased susceptibility to infection with mite load. The probability of acquiring additional mites among males increased more rapidly compared to female flies. Current infection status can potentially determine the risk of further infection, the host propensity and ability to disperse, with consequence for hosts and parasites at the individual, population and species level.
Altered social decision making in patients with chronic pain

Published: November 2021

AbstractBackgroundChronic pain affects up to 20% of the population, impairs quality of life and reduces social participation. Previous research reported that pain-related perceived injustice covaries with these negative consequences. The current study probed whether chronic pain patients responded more strongly to disadvantageous social inequity than healthy individuals.MethodsWe administered the Ultimatum Game, a neuroeconomic social exchange game, where a sum of money is split between two players to a large sample of patients with chronic pain disorder with somatic and psychological factors (n = 102) and healthy controls (n = 101). Anonymised, and in truth experimentally controlled, co-players proposed a split, and our participants either accepted or rejected these offers.ResultsChronic pain patients were hypersensitive to disadvantageous inequity and punished their co-players for proposed unequal splits more often than healthy controls. Furthermore, this systematic shift in social decision making was independent of patients’ performance on tests of executive functions and risk-sensitive (non-social) decision making .ConclusionsOur findings indicate that chronic pain is associated with anomalies in social decision making (compared to healthy controls) and hypersensitivity to social inequity that is likely to negatively impact social partaking and thereby the quality of life.
Are workers musicians? Kesha Sebert, Johanna Wagner and the gendered commodification of star singers, 1853–2014
Authors: Stahl Matt 
Published: November 2021

AbstractThe legal history of pop singer-songwriter Kesha Sebert has brought to light serious problems of gender and power in the US recording industry: it remains male dominated to its core. These contemporary problems have specific historical origins. Contextualising the 2008–2014 lawsuit between two rival producers over the exclusive right to Kesha's labour power suggests that elements of Victorian gender relations and class war were baked into the doctrine on which that 21st century case turned. Drawing empirically on court documents, and analytically on perspectives from history and sociology as well as feminist legal scholarship, this paper explains the persistent vitality of a ‘gendered erotic triangle’ in music production. By contextualising Kesha's gendered legal triangulation, and analysing a seemingly technical quibble about the interpretation of a statute of (temporal) limitation, this paper frames the commodification of singers’ labour power as central to a gendered project of class domination.
Reasoning on Multirelational Contextual Hierarchies via Answer Set Programming with Algebraic Measures
Authors: BOZZATO LORIS , EITER THOMAS , KIESEL RAFAEL 
Published: November 2021

AbstractDealing with context-dependent knowledge has led to different formalizations of the notion of context. Among them is the Contextualized Knowledge Repository (CKR) framework, which is rooted in description logics but links on the reasoning side strongly to logic programs and Answer Set Programming (ASP) in particular. The CKR framework caters for reasoning with defeasible axioms and exceptions in contexts, which was extended to knowledge inheritance across contexts in a coverage (specificity) hierarchy. However, the approach supports only this single type of contextual relation and the reasoning procedures work only for restricted hierarchies, due to nontrivial issues with model preference under exceptions. In this paper, we overcome these limitations and present a generalization of CKR hierarchies to multiple contextual relations, along with their interpretation of defeasible axioms and preference. To support reasoning, we use ASP with algebraic measures, which is a recent extension of ASP with weighted formulas over semirings that allows one to associate quantities with interpretations depending on the truth values of propositional atoms. Notably, we show that for a relevant fragment of CKR hierarchies with multiple contextual relations, query answering can be realized with the popular asprin framework. The algebraic measures approach is more powerful and enables, for example, reasoning with epistemic queries over CKRs, which opens interesting perspectives for the use of quantitative ASP extensions in other applications.
Utilizing Treewidth for Quantitative Reasoning on Epistemic Logic Programs

Published: November 2021

AbstractExtending the popular answer set programming paradigm by introspective reasoning capacities has received increasing interest within the last years. Particular attention is given to the formalism of epistemic logic programs (ELPs) where standard rules are equipped with modal operators which allow to express conditions on literals for being known or possible, that is, contained in all or some answer sets, respectively. ELPs thus deliver multiple collections of answer sets, known as world views. Employing ELPs for reasoning problems so far has mainly been restricted to standard decision problems (complexity analysis) and enumeration (development of systems) of world views. In this paper, we take a next step and contribute to epistemic logic programming in two ways: First, we establish quantitative reasoning for ELPs, where the acceptance of a certain set of literals depends on the number (proportion) of world views that are compatible with the set. Second, we present a novel system that is capable of efficiently solving the underlying counting problems required to answer such quantitative reasoning problems. Our system exploits the graph-based measure treewidth and works by iteratively finding and refining (graph) abstractions of an ELP program. On top of these abstractions, we apply dynamic programming that is combined with utilizing existing search-based solvers like (e)clingo for hard combinatorial subproblems that appear during solving. It turns out that our approach is competitive with existing systems that were introduced recently.

Several studies with barley straw (e.g. Wahed et al, 1990) and sorghum stover (e.g. Osafo, 1993) have shown improvements in intake with increasing ‘ad libitum’ amounts offered. Furthermore, these studies have demonstrated that sheep and goats offered barley straw or sorghum stover in long, unprocessed form, increase intake by selecting for leaf and leaf sheath, and against stem. This phenomenon offers a simple feeding strategy to use selective feeding behaviour to improve intake and hence production. The aim of the present experiment was to study the effect of offering increasing amounts of long maize stover on intake and selection by dairy cows.Six, early- to mid-lactation Ayrshire and Friesian cows (live weight, M, 430 kg) were used in a double 3x3 Latin square design with 24-day (d) feeding periods. Cows were offered long (unchopped) maize stover at low, medium or high ‘ad libitum’ rates, i.e. 31, 59 or 87 g dry matter (DM)/kg M.d. Cows also received 3.2 kg DM/d of cotton seed cake (339 g/kg DM crude protein) in two meals at milking (0700 h and 1800 h). Stover was offered in one meal daily, at 0700 h, after collecting refusals from the previous day. Amounts of stover offered and refused were weighed daily. Samples of offered stover (0.5 kg) and refused stover (0.5 kg) were analysed for DM daily. All refused stover and 4.0 kg samples of offered stover were botanically fractionated, daily, into stem (S), leaf (L), sheath (Sh) and husk (H). Milk yield was recorded daily and cows weighed at the start and end of each period.

Earlier studies at CEDAR established the positive effects on intake and milk production when forages other than grass were incorporated into dairy cows rations. The area of forage maize and its integration in UK dairy rations continues to increase and as a result has generated considerable interest in supplementation of diets based on maize (MS) and grass silage (GS). The aim of the current study was to determine the effect of using starch (S) and fibre (F) based concentrates on feed intake and milk production of Friesian cows offered a forage mixture of MS and GS in a 3:1 DM ratio.Forty individually fed multiparous Friesian cows were used in a continuous design study. At week 3 of lactation cows were allocated to one of four treatment groups (Table 1), in which all cows were offered ad libitum access to a forage mixture containing on a DM basis 750 g/kg MS and 250 g/kg GS and 10 kg fresh weight/d of either a starch (229 g starch and 58 g NDF kg/DM) or fibre (85 g starch and 124 g NDF/kg DM) based concentrate. Both concentrates contained 237 g CP and 13.1MJ ME/kg DM and were offered twice dairy in equal quantities.

Increases in yields of milk and milk protein have been observed from dairy cows offered a high protein supplement during the dry period (Van Saun, Idleman and Sniffen, 1993; Moorby, Dewhurst and Marsden, 1996). One possible mechanism for this is an accumulation of maternal body protein during late pregnancy and its later release during lactation. This experiment was designed to investigate the effect of diet on the potential of dairy cows to accumulate and release body nitrogen over the course of the dry period and the first 20 weeks of lactation.Twelve multiparous Holstein-Friesian cows were offered one of three diets for 6 weeks prior to calving, with 4 animals per diet, in an continuous design experiment. Animals were offered ad libitum access to A) grass silage only (medium protein), B) a grass silage/barley straw mix (60:40 on a dry matter basis) (low protein), or C) grass silage plus 0.5 kg/d high protein maize gluten meal (high protein). After calving, all animals were offered a standard lactation diet based on ad libitum grass silage plus 10 kg/d concentrate to week 12 of lactation, with 7 kg/d thereafter. Animals were housed in individual stalls for 6 d N-balance procedures on three separate occasions in two groups of six animals: during the dry period (at approximately 3 to 4 weeks before calving), early-lactation (weeks 7 to 8 after calving) and mid-lactation (weeks 17 to 18).

Published: November 2021

Providing high levels of nonstructural carbohydrate (NSC) in ruminant diets tends to change fermentation lowering rumen pH and reduce milk fat content. Balancing readily available N and energy-yielding carbohydrate may enhance microbial growth rate, alter fermentation and fibre digestion in the rumen, which subsequently may have an impact on nutrient supply to host animal. Therefore, the objective of this study was to measure the effects of dietary nonstructural carbohydrate and protein level on intake, ruminal fermentation and performance of dairy cows using cassava as main energy source.Forty-two crossbred cows (60.9% Holstein Friesian, 26.8% Danish Red, 10.2% Red Sindi) at a mean of 71.0 ± 28.5 days in milk (DIM) with a pre-treatment milk yield of 13.2 ± 2.2 kg/d and a BW 373.1 ± 33.4 kg. Cows were tethered in stalls and randomly allocated to receive one of six total mixed ration (TMR) on ad-lib basis. Isocaloric diets (ME 11.2 MJ/kg) were formulated to contain Ruzi grass silage and a concentrate mix (20:80 ratio) containing NSC (30, 35, 40%) in combination with 2 levels of crude protein (15.7, 18.4%).

Forsling et al. (1984) have shown that exposure to vibration and noise leads to raised concentrations of plasma lysine vasopressin (LVP) in pigs. Pigs can exhibit symptoms of travel sickness during road transport even when, following commercial practice, they are not fed before transportation. These symptoms appear to be associated with elevated concentrations of plasma LVP (Bradshaw et al. in press). We wished to establish whether concentrations of plasma LVP at exsanguination may reveal which pigs had been travel sick during the journey to slaughter and whether those pigs exhibited subsequent poor meat quality.Fifty 90 kg slaughter pigs were transported on a lorry (25 each day for two days, food withdrawn the previous evening at 1700) for five hours (0.49 m2 per pig). RHB travelled in the main body of the vehicle scanning the individually marked pigs every 8 min for incidences of standing, lying and symptoms of travel sickness (sniffing, foaming at the mouth, chomping, retching and vomiting).
Long‐Term Changes in Runoff Generation Mechanisms for Two Proglacial Areas in the Swiss Alps I: Overland Flow
Authors: Maier Fabian , van Meerveld Ilja 
Published: November 2021

AbstractIn many areas of the world, the surface of the earth is changing rapidly. This can affect the partitioning of precipitation into overland flow (OF) and infiltration. OF can reach the stream quickly and thus strongly influences the streamflow response to precipitation. It can also cause surface erosion. However, our knowledge of the changes in OF responses during landscape evolution is still limited. To investigate how hillslope aging effects OF, we studied three plots on four different aged moraines (several decades to ∼13.5 thousand years old) at a silicate and carbonate proglacial area in the Swiss Alps. We used sprinkling experiments to determine OF characteristics (such as the runoff ratio and timing) and used tracers (δ2H and NaCl) to identify the mixing of rainfall and soil water. Sediment concentrations and turbidity measurements provided an estimate of OF‐driven soil erosion rates. The OF ratios were largest (42%) for the oldest moraines because the clay‐rich layer at 20–40 cm below the surface caused saturated OF. However, OF occurred more frequently on the youngest moraines due to the high stone cover. Soil and vegetation development increase the soil water retention capacity and the pre‐event water fractions in OF for the old moraines, but decreased the suspended sediment yield. The results show that OF characteristics and sediment transport change markedly during landscape evolution. This needs to be taken into account when simulating runoff and erosion responses for rapidly changing Alpine areas, and can—together with the outcomes for subsurface flow (see companion paper Maier et al., 2021, https://doi.org/10.1029/2021WR030223)—be used to improve landscape evolution models.
Consistency of noncognitive skills and their relation to educational outcomes in a UK cohort

Published: November 2021

AbstractNoncognitive skills have been shown to associate with a range of health and socioeconomic outcomes. Many studies have relied on cross sectional data and have been unable to assess the longitudinal consistency of noncognitive skill measures. Using data from a UK birth cohort, we investigated a range of noncognitive skills: behavioural problems, social skills, communication, self-esteem, persistence, locus of control, empathy, impulsivity and personality. We assessed their consistency over a 17-year period throughout childhood and adolescence (age 6 months to 18 years), their genomic architecture, and their associations with socioeconomic outcomes. We found high longitudinal measurement consistency for behavioural and communication skills, but low consistency for other noncognitive skills, suggesting a high noise to signal ratio. We observed consistent non-zero heritability estimates and genetic correlations for only behavioural difficulties. Using aggregate measures of each skill over time, we found evidence of phenotypic correlations and heritability ($$h_{SNP}^2$$

= 0.1–0.2) for behaviour, communication, self-esteem and locus of control. Associations between noncognitive skills and educational outcomes were observed for skills measured in mid to late childhood but these were at most a third of the size of IQ-education associations. These results suggest that measures designed to capture noncognitive skills may be subject to considerable response heterogeneity or measurement error. Aggregate measures that leverage repeat responses from longitudinal data may offer researchers more reliable measures that better identify underlying noncognitive skills than cross sectional measures.

Published: November 2021

AbstractEndogenous clocks generate rhythms in gene expression, which facilitates the organisms to cope through periodic environmental variations in accordance with 24-h light/dark time. A core question that needs to be elucidated is how such rhythms proliferate throughout the cells and regulate the dynamic physiology. In this study, we demonstrate the role of REGγ as a new regulator of circadian clock in mice, primary MEF, and SY5Y cells. Assessment of circadian conduct reveals a difference in circadian period, wheel mode, and the ability to acclimate the external light stimulus between WT and KO littermates. Compared to WT mice, REGγ KO mice attain the phase delay behavior upon light shock at early night. During the variation of 12/12 h light/dark (LD) exposure, levels of Per1, Per2, Cry1, Clock, Bmal1, and Rorα circadian genes in suprachiasmatic nucleus are significantly higher in REGγ KO than in WT mice, concomitant with remarkable changes in BMAL1 and PER2 proteins. In cultured cells depleted of REGγ, serum shock induces early response of the circadian genes Per1 and Per2 with the cyclic rhythm maintained. Mechanistic study indicates that REGγ directly degrades BMAL1 by the non-canonical proteasome pathway independent of ATP and ubiquitin. Silencing BMAL1 abrogates the changes in circadian genes in REGγ-deficient cells. However, inhibition of GSK-3β, a known promoter for degradation of BMAL1, exacerbates the action of REGγ depletion. In conclusion, our findings define REGγ as a new factor, which functions as a rheostat of circadian rhythms to mitigate the levels of Per1 and Per2 via proteasome-dependent degradation of BMAL1.
