The Effects of a Structured Curriculum on Preschool Effectiveness: A Field Experiment
2021
Abstract: This study tests an intervention that introduces a structured curriculum for five-year-olds into the universal preschool context of Norway, where the business as usual is an unstructured curriculum. We conduct a field experiment with 691 five-year-olds in 71 preschools and measure treatment impacts on children’s development in mathematics, language, and executive functioning. The nine-month intervention has effects on child development at post-intervention and the effects persist one year following the end of the treatment. The effects are mainly driven by the preschools identified as low-quality at baseline, indicating that a structured curriculum can reduce inequality in early c…

Permanent Porosity in Hydroxamate Titanium-Organic Polyhedra.
2021
Following the synthesis of hydroxamate titanium–organic frameworks, we now extend these siderophore-type linkers to the assembly of the first titanium–organic polyhedra displaying permanent porosity. Mixed-linker versions of this molecular cage (cMUV-11) are also used to demonstrate the effect of pore chemistry in accessing high surface areas of near 1200 m2·g–1.
The House on Mango Street: A Parable of Degeneration or a Chicana Rewriting of Charles Kingsley’s The Water-Babies
2021
Reading Charles Kingsley’s The Water-Babies (1863) makes it possible for Esperanza Cordero to imagine an idyllic site of empowered identity in The House on Mango Street. Yet, I argue that Esperanza’s transformed identity can only reside outside her original community and that her journey from the sad red house of Mango Street to her reconceived clean house at the end of the text is necessarily a trajectory of desired uprootedness that follows the script presented in The Water-Babies. Like Tom, Kingsley’s protagonist, Esperanza undergoes a metamorphosis to shed off the traits that categorize her as Chicana in order to embrace a remodeled subjectivity and, consequently, become an ontologicall…
Online grocery shopping before and during the COVID-19 pandemic: A meta-analytical review.
2021
The COVID-19 pandemic has forced people to limit their physical interactions, which has led to explosive growth in online grocery shopping. However, there is no clear consensus in the retailing literature on whether consumers prefer to buy groceries online. The objective of this current study is to synthesize research about online grocery shopping published before and during the COVID-19 pandemic and to develop a conceptual framework about online grocery purchase intentions and their determinants, the mediation effects of consumers’ attitudes, the moderating effects of COVID-19, and control variables. The meta-analysis presents data derived from 50 independent samples with a sample size of …
Venäläisen rockin kehykset yhdysvaltalaisessa lehdistössä : Gorky Park Yhdysvalloissa 1988–1991
2021
1980-luvun lopulla Mihail Gorbatšovin aloittamat reformit mahdollistivat venäläisten rockmuusikoiden lähdön ulkomaille. Moni suuntasi Yhdysvaltoihin, jossa glasnostin myötä oli herännyt runsaasti kiinnostusta venäläiseksi miellettyjä ilmiöitä kohtaan. Kiinnostus ilmeni kuitenkin ennen kaikkea mediassa, kaupallisen menestyksen jäädessä laihaksi. Yhdysvaltoihin saapuneet venäläiset rockyhtyeet saivatkin kaupalliseen suosioonsa nähden suhteettoman paljon huomiota osakseen erityisesti maan sanomalehdistössä. Artikkelissani tarkastelen ilmiötä moskovalaisen Gorky Park-yhtyeen kautta. Yhdysvaltalainen lehdistö käsitteli yhtyettä pääasiassa kahden kehyksen kautta. Kehitysoptimismi kehyksessä yhtye…

Under the broad terms of metal chalcohalides, there exists a plethora of semiconductor materials with different chemical, structural, and optoelectronic characteristics. While some have already been implemented in solar cells with power conversion efficiencies up …
Aneurysmal bone cyst of the spine in adult patients: A systematic review and comparison of primary vs secondary lesions.
2021
Background: Spine aneurysmal bone cysts (ABCs) rarely occur in adults. Primary and secondary lesions may show some differences and require appropriate treatments. Objective: To systematically review the literature on adult spine ABCs. Methods: PubMed, EMBASE, Scopus, and Web-of-Science were searched. Clinical-radiological features, treatments, and outcomes were analyzed and compared between primary vs secondary adult spine ABCs. Results: We included 80 studies comprising 220 patients. Primary spine ABCs were more frequent (76.4%). Main symptoms were lower-back-pain (42.8%) and motor deficits (31.2%). Tumors were mostly thoracic (31.4%) or cervical (26.8%), showing lytic (70.4%) and/or cysti…
Chemical composition and particle size influence the toxicity of nanoscale plastic debris and their co-occurring benzo(α)pyrene in the model aquatic …
2021
Little is known about how particle chemical composition and size might influence the toxicity of nanoscale plastic debris (NPD) and their co-occurring chemicals. Herein, we investigate the toxicity of 3 × 1010 particles/L polyethylene (PE, 50 nm), polypropylene (PP, 50 nm), polystyrene (PS, 200 and 600 nm), and polyvinyl chloride (PVC, 200 nm) NPD and their co-occurring benzo(a)pyrene (BaP) to Daphnia magna and Danio rerio. During the 21 days of exposure to PE 50 nm and PS 200 nm, the number of broods produced by D. magna decreased compared to other treatments. Exposure to BaP alone did not produce any effects on the reproduction of the daphnids, however, the mixture of BaP with PS (200 or …
Au revoir Paris! Spanish regions closer to the EU average and further away from the leaders
2021
This paper confirms that Spanish regions in 2015 were closer to the EU average in labour productivity than in 2000, but further away from the richest regions such as Île de France. A dynamic shift-share analysis at a 10-industry level of disaggregation shows that the main driver of convergence with the EU average is catch-up in labour productivity within the same industry, while disparities with the top regions (especially Île de France) mainly involve differences in patterns of specialization (between-industry divergence) followed by technological divergence (within-industry effect). The industry mix of the regions reveals that a new pattern of specialization is taking shape in Europe, dri…
Resting-State Functional Magnetic Resonance Imaging for Surgical Neuro-Oncology Planning: Towards a Standardization in Clinical Settings
2021
Resting-state functional magnetic resonance imaging (rest-f-MRI) is a neuroimaging technique that has demonstrated its potential in providing new insights into brain physiology. rest-f-MRI can provide useful information in pre-surgical mapping aimed to balancing long-term survival by maximizing the extent of resection of brain neoplasms, while preserving the patient’s functional connectivity. Rest-fMRI may replace or can be complementary to task-driven fMRI (t-fMRI), particularly in patients unable to cooperate with the task paradigm, such as children or sedated, paretic, aphasic patients. Although rest-fMRI is still under standardization, this technique has been demonstrated to be feasible…
Device-measured physical activity, adiposity and mortality: a harmonised meta-analysis of eight prospective cohort studies.
2021
BackgroundThe joint associations of total and intensity-specific physical activity with obesity in relation to all-cause mortality risk are unclear.MethodsWe included 34 492 adults (72% women, median age 62.1 years, 2034 deaths during follow-up) in a harmonised meta-analysis of eight population-based prospective cohort studies with mean follow-up ranging from 6.0 to 14.5 years. Standard body mass index categories were cross-classified with sample tertiles of device-measured total, light-to-vigorous and moderate-to-vigorous physical activity and sedentary time. In five cohorts with waist circumference available, high and low waist circumference was combined with tertiles of moderate-to-vigor…

2021
Qvenild T, Fjeld E, Fjellheim A, Hammar J, Hesthagen T and Lakka H-K. 2021. Upper thermal threshold of Lepidurus arcticus (Branchiopoda, Notostraca) in lakes on the southern outreach of its distribution range. Fauna norvegica 41: 50–88. The Arctic tadpole shrimp Lepidurus arcticus has a circumpolar distribution and the Scandes (Fennoscandian Mountains) marks its southernmost limit in Europe. Within this area, 391 natural and 88 regulated lakes with L. arcticus have been identified, of which 87% are above the treeline. The lakes hosting L. arcticus decrease in altitude from south to north, which results from its temperature preferences. The majority of the locations are at a lower lake air t…

Variability of Classification Results in Data with High Dimensionality and Small Sample Size
2021
The study focuses on the analysis of biological data containing information on the number of genome sequences of intestinal microbiome bacteria before and after antibiotic use. The data have high dimensionality (bacterial taxa) and a small number of records, which is typical of bioinformatics data. Classification models induced on data sets like this usually are not stable and the accuracy metrics have high variance. The aim of the study is to create a preprocessing workflow and a classification model that can perform the most accurate classification of the microbiome into groups before and after the use of antibiotics and lessen the variability of accuracy measures of the classifier. To ev…

Interleukin 9 neutralisation reduces collagen-induced arthritis severity in mouse models.
2021
Objective Interleukin 9 (IL-9) is a mediator of tissue damage in several inflammatory diseases. In this study we aimed to evaluate the effects of in vivo IL-9 neutralisation in mice developing collagen induced arthritis (CIA). Methods DBA/1 were immunised with collagen in Freund’s complete adjuvant (CFA) to induce arthritis. Anti-IL-9 mAb was injected in mice after the onset of arthritis (Group A) or on the same day as sensitisation and again on the day of the challenge (Group B). Histological analysis was performed in joints of mice and spleen cells were also analysed by flow cytometry. A geneset analysis was carried out on whole tarsal joint tissue transcriptomes. Results IL-9 was over-ex…
Tailoring Third-Harmonic Diffraction Efficiency by Hybrid Modes in High-Q Metasurfaces
2021
Metasurfaces are versatile tools for manipulating light; however, they have received little attention as devices for the efficient control of nonlinearly diffracted light. Here, we demonstrate nonlinear wavefront control through third-harmonic generation (THG) beaming into diffraction orders with efficiency tuned by excitation of hybrid Mie-quasi-bound states in the continuum (BIC) modes in a silicon metasurface. Simultaneous excitation of the high-Q collective Mie-type modes and quasi-BIC modes leads to their hybridization and results in a local electric field redistribution. We probe the hybrid mode by measuring far-field patterns of THG and observe the strong switching between (0,-1) and…
Suomen tiedontuotannon regiimi : yksi vai monta?

SARS-CoV-2 infection and venous thromboembolism after surgery: an international prospective cohort study
2021
SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 da…

Energy Retrofit. A Case Study—Santi Romano Dormitory on the Palermo University
2021
Electrical and thermal consumption related to buildings, whether civil, commercial, public, or of any other kind, is very much in focus today. With today’s targets for energy savings, reduction of consumption, and environmental impact, it is necessary to carry out energy retrofits to modernize installations and their management. The realization of an effective improvement requires a careful analysis of the case study because each category of building has different requirements such as different load profiles and different installations and needs. This was carried out by studying the electrical and thermal load profiles. A good initial energy audit can provide the retrofit solutions capable …

Molecular data attest to the occurrence of autochthonous Daphnia pulex (Crustacea, Branchiopoda) populations in Sicily, Italy
2021
Biological invasions are known to be among the most important threats to the long-term conservation of native biota, and their effects might be even more difficult to contrast when they are cryptic, i.e., when the non-native invaders cannot be easily recognised based on morphology, and can thus be confused with native taxa. Such cryptic invasions are known to widely occur in the cladoceran genus Daphnia O.F. Müller, 1785, so that the actual distribution and status of most species and lineages need to be checked with a genetic approach. In the frame of this work, we investigated if the Sicilian populations of D. (Daphnia) pulex Leydig, 1860 belonged to the allochthonous North American lineag…

Extracting Deformation-Aware Local Features by Learning to Deform
2021
Despite the advances in extracting local features achieved by handcrafted and learning-based descriptors, they are still limited by the lack of invariance to non-rigid transformations. In this paper, we present a new approach to compute features from still images that are robust to non-rigid deformations to circumvent the problem of matching deformable surfaces and objects. Our deformation-aware local descriptor, named DEAL, leverages a polar sampling and a spatial transformer warping to provide invariance to rotation, scale, and image deformations. We train the model architecture end-to-end by applying isometric non-rigid deformations to objects in a simulated environment as guidance to pr…

Poetische transnationaliteit: noorderwind
2021
Ciò che lega le raccolte poetiche di Radna Fabias e Kira Wuck è l’inscindibile nesso con il fluire del tempo che rappresenta di volta in volta il mutare degli eventi che sconvolge le esistenze personali; l'inatteso, l'inaspettato e l'imponderabile che pervade le vicende storiche, individuali e collettive inverandosi come qualcosa di profondamente conturbante della condizione di precarietà dell'uomo novecentesco. The poetic collections of Radna Fabias and Kira Wuck are binded by the inseparable link with the flow of time that represents from time to time, the changing of events that upsets personal lives; the unexpected and the imponderable that pervades historical, individual and collective…
