The Goddess Ops in Archaic Rome

This article analyses the evidence on the goddess Ops in Archaic Rome, focussing on her two festivals in the archaic feriale, and on her connection with the god Consus. It contends that Ops was related to a nuanced concept of abundance, which included associations with sovereignty. At the same time, it questions the theory that Ops and Consus were associated with agriculture and granaries. It also considers the developing roles of Ops in Republican Rome, to verify if, and to what extent, they show continuity with the archaic period

Comorbid depressive disorders in ADHD. the role of ADHD severity, subtypes and familial psychiatric disorders

ObjectiveaaTo evaluate the presence of Major Depressive Disorder (MDD) and Dysthymic Disorder (DD) in a sample of Italian children with Attention Deficit Hyperactivity Disorder (ADHD) and to explore specific features of comorbid depressive disorders in ADHD. MethodsaaThree hundred and sixty-six consecutive, drug-naïve Caucasian Italian outpatients with ADHD were recruited and comorbid disorders were evaluated using DSM-IV-TR criteria. To evaluate ADHD severity, parents of all children filled out the ADHD Rating Scale. Thirty-seven children with comorbid MDD or DD were compared with 118 children with comorbid conduct disorder and 122 without comorbidity for age, sex, IQ level, family psychiatric history, and ADHD subtypes and severity. Resultsaa42 of the ADHD children displayed comorbid depressive disorders: 16 exhibited MDD, 21 DD, and 5 both MDD and DD. The frequency of hyperactive-impulsive subtypes was significantly lower in ADHD children with depressive disorders, than in those without any comorbidity. ADHD children with depressive disorders showed a higher number of familial psychiatric disorders and higher score in the Inattentive scale of the ADHD Rating Scale, than children without any comorbidity. No differences were found for age, sex and IQ level between the three groups. Conclusions: Consistent with previous studies in other countries, depressive disorders affect a significant proportion of ADHD children in Italy. Patient assessment and subsequent treatment should take into consideration the possible presence of this comorbidity, which could specifically increase the severity of ADHD attention problems

Farmer Perception of Technology and its Impact on Technology Uptake: The Case of Fodder Legume in Central Kenya Highlands.

Technology adoption by farmers is crucial to increasing agricultural productivity hence meeting food and nutrition challenges in Africa. Economists investigating consumer demand have accumulated considerable evidence showing that consumers generally have subjective preferences for product attributes. However, when investigating adoption of new agricultural technologies, economists have lagged behind in analysing how farmers' (the consumer of agricultural technologies) subjective perceptions of technology characteristics affect their adoption decisions. Focusing on farmer perceptions of technologies may provide a better understanding of technology adoption since they deal with the technologies and probably perceive technologies differently from researchers and extension agents. The objective of this paper is to investigate farmers' perception of technology and its impact on adoption using a case study of legume forages in central Kenya highlands. Data from a random sample of 131 farm households in four districts in central Kenya was used. Using participatory techniques, four most important fodder legume attributes to farmers in their adoption decision were identified. These were then used in conjoint analysis. An ordered probit model was estimated to assess relative importance of each attribute to the farmer. A tobit model was also estimated to show the effect of farmers' perception of calliandra and desmodium on probability and intensity of adoption. Results showed that dry season tolerance and economy on land are most important characteristics of fodder legumes to the farmers. It was also found that Calliandra and desmodium were more relevant to the farmers in the area than other fodders. Farmers' perception of the two fodders had a significant impact on their adoption. Consequently, it was recommended that before introducing a technology in an area, it is necessary that the farmers' perception of the technology be analysed Conjoint analysis, ordered probit and tobit estimates, fodder legume adoption.Research and Development/Tech Change/Emerging Technologies,

Multi-task learning for neural image classification and segmentation using a 3D/2D contextual U-Net model

We present a 3D/2D Contextual U-Net model and apply it to segment and classify samples from a heterogeneous mouse brain dataset obtained via X-ray microtomography, which spans 4 distinct brain areas: Striatum, Ventral Posterior Thalamic Nucleus (VP), Cortex, and Zona Incerta (ZI). Our multi-task model takes in a 3D volume and outputs both a 2D segmentation of the central plane and the volume's brain area class, which can then be used to generate 3D reconstructions across samples with heterogeneous microstructure distributions. We investigate various properties of the model, including its quantitative segmentation and classification performance across the 4 brain regions, qualitative performance via the generation of 3D reconstructions, and interpretability via an investigation of the network's latent representations. Because our model performs both classification and segmentation, we also investigate how changing their relative weight during training, via a parameter we call lambda, affects performance and latent representations. Quantitative and qualitative results demonstrate that our model achieves reasonable segmentation and classification performance and can be scaled to large, heterogeneous brain regions. This technique could be used by neuroscientists seeking to automate the creation of multi-scale brain maps that incorporate both microstructure and brain area information.Undergraduat

Potential of remote sensing data to support the seismic safety assessment of reinforced concrete buildings affected by slow-moving landslides

Different forms of hazard can affect structures throughout their existence. The occurrence of a seismic event in areas exposed to different risks or already affected by other phenomena is highly likely, especially in countries characterized by high seismicity and equally high hydrogeological risk, as Italy. Nevertheless, the seismic safety assessment of reinforced concrete (RC) structures is commonly carried out considering the seismic action only, generally applied to an analytical model, neglecting the stress–strain state induced by previous ongoing phenomena. The aim of this work is to highlight the importance of the seismic safety assessment in a multi-hazard analysis, cumulating the action coming from two different hazards: landslide and earthquake. An existing RC building, located in an area affected by an intermittent landslide phenomenon with slow kinematics, that may also be subjected to strong earthquakes, is used as case study. The Differential Synthetic Aperture Radar Interferometry (DInSAR) approach is used to monitor the evolution in time of the landslide. DInSAR deformation data are used to detect surface ground movements applied to building foundations. A non-linear static analysis procedure is implemented for the code-based seismic safety assessment, in two different scenarios. The seismic assessment of the case-study building is implemented in a condition of structure deformed only for gravity loads, and, then, in a state of known landslide-induced deformed configuration. A comparison is proposed between the building seismic safety assessment performed in both cases, with or without the consideration of the landslide-induced displacements, showing the importance of a multi-hazard evaluation

Improved Livelihoods from Grasslands; the Case of Napier Grass in Smallholder Dairy Farms in Kenya

In Kenya, smallholder farmers produce about 80% of the marketed milk. The farming systems vary from mixed farms with up to 10 ha of land and \u3c 10 dairy cows (Gitau et al., 1994; Anon., 1985), to intensive smallholder dairy producers in the high human population central Kenya region with 0.9 to 2 ha of land and 3-4 dairy cows (Staal et al., 2001a). Milk production depends heavily on the cultivation of forages, with Pennisetum purpureum (Napier grass) by far the most important. An estimated 350,000 of the 600,000 smallholder farms in Kenya grow and utilize P. purpureum on their farms. There are various published data indicating the level of dependence on sown forages. In a survey of 21 smallholder dairy farmers in the highlands of Kenya, Romney et al. (2004) found that P. purpureum supplied approximately 40 and 60% of the feed offered to dairy cows in the dry and wet months respectively, with the remaining feed provided by concentrates, crop residues (mainly Zea mays (maize) stover) and other cut and carry fodder such as roadside grass. In the more intensive cut and carry systems of production practiced in central Kenya, McLeod et al. (2003) found that P. purpureum was grown by over 70% of the smallholder farmers in their study area. In farm level characterisation surveys of over 3300 households conducted between 1996 and 2000 in central Kenya, 62% kept livestock and more than 50% were growing P. purpureum. Farmers were also growing fodder legumes such as Sesbania grandiflora (Sesbania), Leucaena leucocephala (Leucaena), Calliandra calothyrsus (Callindra), Desmodium intortum/uncinatum, (Desmodium) and Medicago sativa (Lucerne), but the frequency did not exceed 7.5% (Staal et al., 2001b)

Lagrangian Variational Framework for Boundary Value Problems

A boundary value problem is commonly associated with constraints imposed on a system at its boundary. We advance here an alternative point of view treating the system as interacting "boundary" and "interior" subsystems. This view is implemented through a Lagrangian framework that allows to account for (i) a variety of forces including dissipative acting at the boundary; (ii) a multitude of features of interactions between the boundary and the interior fields when the boundary fields may differ from the boundary limit of the interior fields; (iii) detailed pictures of the energy distribution and its flow; (iv) linear and nonlinear effects. We provide a number of elucidating examples of the structured boundary and its interactions with the system interior. We also show that the proposed approach covers the well known boundary value problems.Comment: 41 pages, 3 figure

Can circumcision be avoided in adult male with phimosis? Results of the PhimoStopTM prospective trial

Background: Circumcision as surgical treatment of adult phimosis is not devoid of complications. Efficacy of alternative non-surgical options is unclear. PhimoStop (TM) is a therapeutic protocol which involves the use of appropriately shaped silicone tuboids of increasing size to obtain a non-forced dilation of the prepuce. The aim of the study was to evaluate the efficacy and durability of results of PhimoStop (TM) device for the treatment of adult male phimosis.Methods: A prospective trial was conducted between 2018 and 2020 on 85 consecutive adult male patients affected by phimosis and with an indication for circumcision. Patients were treated with PhimoStop (TM) protocol and they were evaluated at baseline and after treatment through a subjective (patient self-reported information on various domains of his sexual function) and an objective assessment (evaluation of phimosis severity grade according to the Kikiros scale pre- and post-treatment, re-assessment of indication for circumcision post-treatment and validated questionnaires scores). Primary endpoint was to avoid the scheduled circumcision in 33% of the patients enrolled.Results: Seventy-one patients (84%) completed the device usage phase as per study protocol. Median duration of tuboid application was 60 days. Thirty-seven patients (52.1%) had no indication for circumcision after treatment. Even considering patients lost to follow-up as failures, primary endpoint was reached in 43.5% of cases. There was a significant reduction of the grade of phimosis after treatment (P<0.001). Moreover IIEF-5 showed a statistically significant improvement after treatment (P< 0.001). Thirty/37 patients who met the primary endpoint (81%) still have a successful resolution of their phimosis avoiding circumcision at a median follow-up of 24 months.Conclusions: PhimoStop (TM) device is effective for the treatment of adult male phimosis of Kikiros grade < 2. The results seem to be durable in most patients at a median follow-up of 24 months. Randomized clinical trials are necessary in order to confirm our results and assess cost-efficacy
