The Test–Retest Repeatability of a Rhythm Coordination Test Procedure in 4- to 6-Year-Old Children : A Pilot Study
2020
Moving to music combines the ability of rhythm and coordination. In relation to the musical and motor development of children, sensorimotor synchronization requires the ability to perceive and perform a steady beat. The present pilot study aimed to investigate the test–retest repeatability of a rhythm coordination test procedure in order to pilot the procedure for children. Test–retest repeatability reflects the variation in measurements taken by the rhythm coordination test on the same participant under the same conditions. Ten children (mean age 5.5 years, standard deviation (SD) 0.6) participated in the tests. The test performance was evaluated in points from 0 to 8, separately at a slow…
High-resolution orthophoto map and digital surface models of the largest Argentine Islands (the Antarctic) from unmanned aerial vehicle photogrammetry
2020
This study presents the first high-resolution orthophoto maps and digital surface models (DSMs) of the largest Argentine Islands, West Antarctica. Aerial surveys with small unmanned aerial vehicle (UAV) were performed in Austral summer, 2018, taking 10,041 aerial photographs. Accuracy requirements were ensured using ground control points (GCPs). A resolution of 3.4 and 6.8 cm/px of orthomosaics and DSMs is reached on average, and the RMS reprojection error is 0.22 m on average. We report the morphometric parameters of surveyed islands and discuss issues related to accuracy and the usage of UAVs in polar conditions. This study demonstrates that small and low cost UAVs can be successfully use…
Geomorphology and surface geology of Mount St. Helens volcano
2020
Mount St. Helens is a stratovolcano of the Cascadia volcanic arc well known worldwide for its volcanic collapse and eruption in 1980, which caused considerable destruction and changed the geomorphology of the volcano and of a considerable portion of its surroundings. This paper presents a geomorphology and surface-geology map of both the wider Mount St. Helens, Washington (USA), at the 1:50,000 scale, and of its crater, at the 1:25,000 scale. The map is obtained from the interpretation of two high-resolution, air-borne acquired, digital terrain models, LiDAR dataset, combined with Google Earth imaging, geological information and field surveys. The geomorphology of the area is largely domina…
Geomorphology of the urban area of Palermo (Italy)
2020
The results of a geomorphological study carried out in the urban area of Palermo are summarized in a thematic map. Field survey, analysis of aerial photographs and topographic maps, consultation of historical documents and maps, stratigraphic and topographic reconstruction from numerous wells and subsoil data, and bibliographic search were performed, in order to display the geomorphological changes produced by man over time in a densely populated area and to define the Anthropocene of the study area. Palermo town rises along large marine terrace surfaces cut by small river valleys and bordered by wide degraded and abandoned coastal cliffs. Over the last 2700 years, this area was affected by…
Progenitor death drives retinal dysplasia and neuronal degeneration in a mouse model of Atrip-Seckel syndrome
2020
ABSTRACT Seckel syndrome is a type of microcephalic primordial dwarfism (MPD) that is characterized by growth retardation and neurodevelopmental defects, including reports of retinopathy. Mutations in key mediators of the replication stress response, the mutually dependent partners ATR and ATRIP, are among the known causes of Seckel syndrome. However, it remains unclear how their deficiency disrupts the development and function of the central nervous system (CNS). Here, we investigated the cellular and molecular consequences of ATRIP deficiency in different cell populations of the developing murine neural retina. We discovered that conditional inactivation of Atrip in photoreceptor neurons …
Strategie autofinzionali in "Leggenda privata" di Michele Mari
2019
Leggenda privata (2017) is the latest in a series of autobiographical writings by Michele Mari. The novel is the factual narration of the author's childhood and adolescence, documented by family photos, but is also the narration of a fictional and fantastic situation of writing, where the reader is involved in live recording. In particular, the narrative framework is structured almost like a personal essay that engages dialogically the norms and potentials, opportunities and risks of a theory of autobiography. The purpose of this article is to explore the limits, the difficulties, indeed the impossibility of autobiographical writing in Leggenda Privata, which instead verges towards a comple…
The afterworld space in the "Poem strip" (1969) by Dino Buzzati
2018
L’obiettivo del contributo è l’analisi dello spazio oltremondano in Poema a fumetti(1969) di Dino Buzzati, graphic novelante-litteram. Buzzati riscrive, in chiave ultramoderna e laica, sia il mito di Orfeo ed Euridice, restituendo la centralità alla potenza della musica, sia il mito della discesa agli inferi, toposassoluto della letteratura italiana a partire da Dante e rappresentazione allegorica dell’oltretomba cristiano. In particolare Buzzati inventa una rappresentazione visiva dello spazio dell’aldilà dove sono essenziali due elementi: la continuità/discontinuità dei due mondi, nominalmente diversi, e le cornici che permettono il passaggio da un mondo all’altro. Il motivo ricorrente di…
Irrealis i engelsk, dansk og tysk -en grammatisk kategori uden systemisk adresse
2020
This paper is concerned with the apparent absence of a ‘systemic address’ for the functional category irrealis in grammatical descriptions of English, Danish and German within the framework of systemic functional linguistics (SFL). Based on a thorough discussion of our understanding of this functional grammatical concept, we present a summary of the lexicogrammatical potential of irrealis in English, Danish and German. By comparing and contrasting the three languages, we find among them equivalent connections to other grammatical systems. The existing SFL-descriptions of English, Danish and German offer some proposals with regard to irrealis, but these, to some degree, contradict our findin…
A Role for Judges in Assisted Dying
2009
Medically provoked death, whether euthanasia or assisted suicide, is a common issue for discussion in various forums, participants coming from widely differing fields of knowledge, among who are, of course, doctors. Substantial legal differences exist in Europe on this issue and in an ever-wider Europe, it is essential, for practical reasons, that legislation be standardised. We would like to propose possible regulations that would provide effective safeguards in the application of euthanasia or assisted suicide.
What can Bilfinger teach Olympic sponsors?
2016
Bilfinger SE (Bilfinger) is a leading international engineering and services group (Bilfinger.com, 2015), and was a local sponsor of the 2014 FIFA World Cup. The company is accused of paying bribes through its subsidiary company, Mauell, (dw. com, 2015) to public officials in Brazil for contracts related to the 2014 World Cup (Cassin, 2015). The corruption allegations relate to orders to equip security command centers at twelve host cities during the 2014 World Cup in Brazil (dw.com, 2015). Because Brazil hosted the 2014 FIFA World Cup and will host the 2016 Summer Olympic Games, companies need to consider the risks of many international anti-corruption laws, such as Brazil’s anti-corruptio…
