This paper tests the published section level price and weight data
used in the compilation of the UK Retail Prices Index for consistency
with the theory of the cost-of-living index. We use a nonparametric test
of theoretical consistency and bootstrap statistical methods to estimate
the probability of consistency
STRATEGI ORANG TUA DALAM MENDAMPINGI ANAK BELAJAR DI RUMAH PADA MASA PANDEMI COVID-19 DI TK SYARIF HIDAYATULLAH PASURUAN
Pandemi covid-19 mengakibatkan kegiatan sosial khususnya pendidikan dilakukan di rumah. Kegiatan pembelajaran dilakukan di rumah untuk mengurangi penyebaran covid-19, proses pembelajaran yang dilakukan di rumah ini membutuhkan pendampingan orang tua. Ada dua potensi yang diberikan ketika adanya pendampingan orang tua, dari segi positifnya orang tua dapat meningkatkan kedisiplinan anak saat belajar dan dari segi negatifnya jika orang tua kurang maksimal dalam mendampingi anak, anak dapat melakukan kegiatan yang tak terkendali. Terlebih lagi pada masa pandemi covid-19 sangat diperlukan perndampingan orang tua untuk proses belajar anak dan kegiatan lainnya. Penelitian ini bertujuan untuk mengetahui cara orang tua dalam strategi mendampingi anak belajar di rumah pada masa pandemi Covid-19. Penelitian ini menggunakan pendekatan deskriptif kuantitatif. Responden dalam penelitian ini sebanyak 30 orang tua. Pengumpulan data dilakukan menggunakan instrumen angket, analisis data bersifat deskriptif kuantitaif. Hasil penelitian menujukkan kurang optimal. Terbukti dari hasil rata-rata persentase 40% pada strategi orang tua dapat diartikan bahwa orang tua sudah mulai membiasakan anaknya untuk belajar di rumah dengan jadwal belajar yang sudah disepakati dan 37,13% pada mendampingi anak dapat diartikan bahwa orang tua telah melakukan pendampingan pada anaknya secara maksimal mulai dari kedisiplinan, tata krama, dan kemandirian

In this paper, we propose a direct method and train a Convolutional Neural Network (CNN) that when, at test time, is given a pair of images as input it produces a dense motion field F at its output layer. In the absence of large datasets with ground truth motion that would allow classical supervised training, we propose to train the network in an unsupervised manner. The proposed cost function that is optimized during training, is based on the classical optical flow constraint. The latter is differentiable with respect to the motion field and, therefore, allows backpropagation of the error to previous layers of the network. Our method is tested on both synthetic and real image sequences and performs similarly to the state-of-the-art methods
Nuclear entropy, angular second moment, variance and texture correlation of thymus cortical and medullar lymphocytes: Grey level co-occurrence matrix analysis
Suono e Spettacolo. Athanasius Kircher, un percorso nelle Immagini sonore.
The Society of Jesus made great propaganda efforts throughout the seventeenth century and chose the images and the play as a privileged means to communicate and persuade. Athanasius Kircher, a key figure of the seventeenth century, he decided to dominate the wild nature of sound through Phonurgia Nova, which includes a gallery of powerful symbolic images for Baroque aesthetics. The essay, through the grant of the images from the Library of the Department of Mathematics "Guido Castelnuovo" Sapienza University of Rome, aims to understand, through the pictures offered by Kircher, the sound phenomenon and the spectacle that this produces. In Phonurgia Nova a process of dramatization sound effects takes place, often through machines and "visions" applied to the theatrical reality, as experimental and astonishing environment beloved in baroque. Kircher illustrates the sound through explanatory figures, so to dominate the sound through the eyes. Sound is seen, admired and represented: its spectacle not only takes place through the implementation of sound machines or the "wonders" applied to the theater, but even through images, creating create a sense of wonder in in the erudite person of the seventeenth century
A school-based program implemented by community providers previously trained for the prevention of eating and weight-related problems in secondary-school adolescents : the MABIC study protocol
Background: The prevention of eating disorders and disordered eating are increasingly recognized as public health priorities. Challenges in this field included moving from efficacy to effectiveness and developing an integrated approach to the prevention of a broad spectrum of eating and weight-related problems. A previous efficacy trial indicated that a universal disordered eating prevention program, based on the social cognitive model, media literacy educational approach and cognitive dissonance theory, reduced risk factors for disordered eating, but it is unclear whether this program has effects under more real-world conditions. The main aim of this effectiveness trial protocol is to test whether this program has effects when incorporating an integrated approach to prevention and when previously-trained community providers implement the intervention. Methods/design: The research design involved a multi-center non-randomized controlled trial with baseline, post and 1-year follow-up measures. Six schools from the city of Sabadell (close to Barcelona) participated in the intervention group, and eleven schools from four towns neighboring Sabadell participated in the control group. A total of 174 girls and 180 boys in the intervention group, and 484 girls and 490 boys in the control group were registered in class lists prior to baseline. A total of 18 community providers, secondary-school class tutors, nurses from the Catalan Government's Health and School Program, and health promotion technicians from Sabadell City Council were trained and delivered the program. Shared risk factors of eating and weight-related problems were assessed as main measures. Discussion: It will be vital for progress in disordered eating prevention to conduct effectiveness trials, which test whether interventions are effective when delivered by community providers under ecologically valid conditions, as opposed to tightly controlled research trials. The MABIC project will provide new contributions in this transition from efficacy to effectiveness and new data about progress in the integrated approach to prevention. Pending the results, the effectiveness trial meets the effectiveness standards set down by the Society for Prevention Research. This study will provide new evidence to improve and enhance disordered eating prevention programs
A multimodal cell census and atlas of the mammalian primary motor cortex
ABSTRACT We report the generation of a multimodal cell census and atlas of the mammalian primary motor cortex (MOp or M1) as the initial product of the BRAIN Initiative Cell Census Network (BICCN). This was achieved by coordinated large-scale analyses of single-cell transcriptomes, chromatin accessibility, DNA methylomes, spatially resolved single-cell transcriptomes, morphological and electrophysiological properties, and cellular resolution input-output mapping, integrated through cross-modal computational analysis. Together, our results advance the collective knowledge and understanding of brain cell type organization: First, our study reveals a unified molecular genetic landscape of cortical cell types that congruently integrates their transcriptome, open chromatin and DNA methylation maps. Second, cross-species analysis achieves a unified taxonomy of transcriptomic types and their hierarchical organization that are conserved from mouse to marmoset and human. Third, cross-modal analysis provides compelling evidence for the epigenomic, transcriptomic, and gene regulatory basis of neuronal phenotypes such as their physiological and anatomical properties, demonstrating the biological validity and genomic underpinning of neuron types and subtypes. Fourth, in situ single-cell transcriptomics provides a spatially-resolved cell type atlas of the motor cortex. Fifth, integrated transcriptomic, epigenomic and anatomical analyses reveal the correspondence between neural circuits and transcriptomic cell types. We further present an extensive genetic toolset for targeting and fate mapping glutamatergic projection neuron types toward linking their developmental trajectory to their circuit function. Together, our results establish a unified and mechanistic framework of neuronal cell type organization that integrates multi-layered molecular genetic and spatial information with multi-faceted phenotypic properties
The anthropology of Hilary of Poitiers
This thesis examines the theological of the fourth-century bishop, Hilary of Poitiers, concentrating particularly on two commentaries written at different times in his life. The thesis starts by examining the texts, and demonstrates that Hilary's commentary on Psalm 118 is loosely speaking a translation of Origen; by comparing both authors with Ambrose, the relationship between Origen and Hilary appears much closer than previously thought. The main body of the thesis examines Hilary's anthropological theology. Three chapters look at created human nature, looking at the relationship between body and soul, human nature as imago dei, and the extent to which human nature can be treated as a platonic universal. The general conclusion is that Hilary is not particularly platonic, and at this stage is not particularly stoic either, but rather is eclectic in his choice of philosophical ideas. The influence of Origen is clear but Hilary only uses Origenâs theology critically. There follow four chapters on the Fall and its impact, focussing particularly on its effects on human nature. In particular it is shown that Hilary presages Augustine's teaching of the fallen will; in Hilary the Will is described as being in thrall to her mother-in-law Disobedience. Another human malady is the effect of the passions or emotions, where Hilary is influenced by Stoic ideas of the process of human action; nevertheless, concepts such as apatheia or the propatheiai do not appear in his work. These constraints on human action point towards Hilary's theology of original sin; indeed he appears to be the first author to use the phrase peccata originis in this sense. In the concluding chapter, Hilary's place in the continuum between Origen and Augustine is demonstrated; at very least, original sin cannot be called an African doctrine, since it first is named by Hilary, a Gaul.</p
