Motivating Physical Activity for Individuals with Intellectual Disability through Indoor Bike Cycling and Exergaming.
2022
People with intellectual disabilities have more sedentary lifestyles than the general population. Regular physical activity is of both medical and social importance, reducing the risk of cardiovascular disease and promoting functioning in everyday life. Exergames have been envisioned for promoting physical activity; however, most of them are not user-friendly for individuals with intellectual disabilities. In this paper, we report the design, development, and user acceptance of a mobile health solution connected to sensors to motivate physical activity. The system is mounted on an indoor stationary bicycle and an ergometer bike tailored for people with intellectual disabilities. The develop…

Regional headquarters and foreign direct investment
2022
Headquarters (HQs) provide a wide range of services, playing a fundamental role in Foreign Direct Investment (FDI). We use the structural gravity equation to investigate the effect of regional HQs on three dimensions of FDI (number of foreign projects, capital investment, and jobs) at the country-pair-sector level. Furthermore, we explore two underlying mechanisms that help explain this relationship: financial constraints and informational costs and uncertainty. We find a positive effect of regional HQs on FDI, as well as intercountry and intersector spillovers. Our results are robust, accounting for HQ intensity, domestic investment, and endogeneity tests.

Vacuum impregnation is considered a cold formulation technology since it allows the incorporation of a desired functional compound into porous plant tissue without applying any heat. It is widely used in combination with the drying process to obtain added-value snacks. The aim of this work was to evaluate the effect of two trehalose concentrations (5 and 10% w/w) on: (i) the water state and texture evolution during the air drying (50 °C, 8 h) of apple snacks vacuum impregnated with blueberry juice, and on (ii) the colour of the final dried apple snacks. The results of nuclear magnetic resonance (NMR) showed that trehalose affects the water mobility of the samples during drying especially af…
A dynamic air–liquid interface system for in vitro mimicking of the nasal mucosa
2022
The development of an in vitro 3D model for the growth of the nasal mucosa cells can improve the therapy and the study of pathological states for subjects with chronic airway conditions. We have previously characterized a system consisting of a scaffold with an internal channel and a perfusion bioreactor with two independent flows provided by an external and an internal circuit, respectively. In this paper, this system was designed as a model of the nasal cavity, in which cells, grown on the inner surface of the scaffold channel, would be in contact at the same time with both culture medium, supplied by the external circuit, and air, provided with the internal flow. To ensure adequate nutri…

Prenatal Diagnosis of Bovine Aortic Arch Anatomic Variant
2022
Fetal aortic arch development is an early and complex process that depends on many genetic and environmental factors. The final aortic arch varies greatly; it may take the form of a normal arch, anatomic variant (AAAV) with a common origin to that of the innominate artery and left common carotid artery (formerly known as “bovine aortic arch” (with an incidence of up to 27%)) or one of multiple pathological conditions. The present study aimed to establish the feasibility and impact of prenatal anatomic arch variants’ diagnosis. A retrospective study of 271 fetal second- and third-trimester anomaly scans was performed in our tertiary center. Examinations that evaluated the s…
Distance Learning for Social Distancing through LMOOCs: From Local to Massive and Back
2022
This chapter discusses the first step of the adaptation of a Language Massive Open Online Course (LMOOC) offered on EdX4 to be used in higher education contexts as a result of social distancing measures imposed by the COVID19 outbreak and the sudden pivot to online learning. The LMOOC contents recently underwent a process of redesign and conversion from small-scale to massive and now the opposite move is necessary: the LMOOC is to go local by becoming embedded in English classes in higher education contexts. Participants’ feedback was analyzed and compared with the criteria from a MOOC analysis matrix in terms of content variety, quality of contents and instructors, linguistic level and ade…
Emerging Cyber risk Challenges in Maritime Transportation
2022
Maritime security and surveillance have become one of the main areas in managing overall situational awareness. For example, the growing importance of maritime traffic in cross-border trade has created new pressures to develop new technologies for accident prevention, especially in the ports. Maritime safety is also a matter of concern for continuity management. Automatic ship alarm systems, coastal radars and coastal cameras are not alone sufficient equipment to build maritime awareness. The Universal Shipborne Automatic Identification System (AIS) is a ship transponder system that is a globally used tracking system, but highly vulnerable to hacking. A major maritime traffic problem arises…
Data Mining for the Security of Cyber Physical Systems Using Deep-Learning Methods
2022
Cyber Physical Systems (CPSs) have become widely popular in recent years, and their applicability have been growing exponentially. A CPS is an advanced system that incorporates a computation unit along with a hardware unit, allowing for computing processes to interact with the physical world. However, this increased usage has also led to the security concerns in them, as they allow potential attack vendors to exploit the possibilities of committing misconduct for their own benefit. It is of paramount importance that these systems have comprehensive security mechanisms to mitigate these security threats. A typical attack vector for a CPS is malicious data supplied by compromised sensors that…

A Design of Global Workspace Model with Attention: Simulations of Attentional Blink and Lag-1 Sparing
2022
There are many developed theories and implemented artificial systems in the area of machine consciousness, while none has achieved that. For a possible approach, we are interested in implementing a system by integrating different theories. Along this way, this paper proposes a model based on the global workspace theory and attention mechanism, and providing a fundamental framework for our future work. To examine this model, two experiments are conducted. The first one demonstrates the agent’s ability to shift attention over multiple stimuli, which accounts for the dynamics of conscious content. Another experiment of simulations of attentional blink and lag-1 sparing, which are two well-stu…
ODO VON BAYEUX ZWISCHEN NORMANDIE, ENGLAND UND PALERMO. NEUE ERKENNTNISSE ÜBER SEINE BEISETZUNG
2022
Nel 1096 Eudes (o Odo) di Conteville, fratellastro di Guglielmo "il Conquistatore", vescovo di Bayeux (che probabilmente commissionò il famoso arazzo che celebra la conquista normanna dell'Inghilterra nel 1066) e già conte di Kent, all'età di quasi sessantaquattro anni, forse spinto da segreti rimorsi, partì per la prima crociata predicata da papa Urbano II per liberare la tomba di Cristo in Terra Santa. Con lui c'era suo nipote Roberto II "Courteheuse" duca di Normandia a capo della spedizione e, tra gli altri nobili normanni, Gilbert Fitz-Osbern vescovo di Evreux. Ospite a Palermo del Gran Conte Roger Hauteville, si ammala gravemente e muore il 5 gennaio (o febbraio) 1097. La sua tomba, c…

Variation in the use of constructed action according to discourse type and age in Finnish Sign Language
2022
This paper presents a study of the use of constructed action (CA) in the stories and conversations of adult Finnish Sign Language (FinSL) signers of different ages. CA is defined here as a type of depiction in which a signer enacts the actions, feelings, thoughts and utterances of discourse referents with different parts of their body. Most studies on CA in sign languages have been done on the basis of signed storytelling, and little is known about how the use of CA varies in different discourse types. The use of CA has also been noted to vary between individual signers, but we do not yet know much about the socio-individual phenomena that may be linked to this variation. In the present stu…
A Resilient Smart Architecture for Road Surface Condition Monitoring
2022
Nowadays, road surface condition monitoring is a challenging problem that cannot be addressed with traditional techniques. In this paper we propose an architecture for monitoring the condition of road surfaces based on the paradigm of Mobile Crowdsensing. First, a surface detection module extracts high level features from raw data, indicating the presence of hazards. Then, in order to make the system resilient to attacks, the system exploits a reputation module to identify malicious users and filter out unreliable data. Finally, a truth discovery module aggregates the resulting information to obtain the desired truth values. Experiments carried out on a real world dataset prove the resilien…
Anomaly Detection and Classification of Household Electricity Data : A Time Window and Multilayer Hierarchical Network Approach
2022
With the increasing popularity of the smart grid, huge volumes of data are gathered from numerous sensors. How to classify, store, and analyze massive datasets to facilitate the development of the smart grid has recently attracted much attention. In particular, with the popularity of household smart meters and electricity monitoring sensors, a large amount of data can be obtained to analyze household electricity usage so as to better diagnose the leakage and theft behaviors, identify man-made tampering and data fraud, and detect powerline loss. In this paper, the time window method is first proposed to obtain the features and potential periodicity of household electricity data. Combining th…
Fibred-categorical obstruction theory
2022
Abstract We set up a fibred categorical theory of obstruction and classification of morphisms that specialises to the one of monoidal functors between categorical groups and also to the Schreier-Mac Lane theory of group extensions. Further applications are provided to crossed extensions and crossed bimodule butterflies, with in particular a classification of non-abelian extensions of unital associative algebras in terms of Hochschild cohomology.
Prediction of river discharges at confluences based on Entropy theory and surface-velocity measurements
2022
Hydrodynamic features of the confluence zone of large rivers are complicated because of their three-dimensional flow structure. The confluence between the Rio Negro and the Rio Solimões, characterised by black and white waters, respectively, ranks among the largest river junctions on Earth. An Entropy-based investigation was carried out to assess the discharge and analyse the 2D structure of velocity distribution for large river flows relying on monitoring of near-surface velocity only. The estimated flow data where compared with in-situ ADCP data gathered across some transects of the Negro and Solimões rivers during both low and relatively high flow conditions. Results are illustrated thro…
Debunking the myth of high achievers in Finnish primary teacher education: first-year preservice teachers’ learning strategies and study success
2022
This study aimed to explore the admitted students of Finnish primary teacher education programmes from the viewpoint of learning strategies, and academic success. An overall view was derived from national register data, which were supplemented with questionnaire data gathered from three teacher education units (N = 216). Primary teacher programmes currently seem to attract and select mediocre secondary school graduates from academic perspective, contrary to previous studies. Furthermore, women enter the programmes with higher exam scores than men and have more success in their studies. Based on their learning strategies, students were divided into subgroups of deep and independent learners,…

2022
Il lavoro presentato in questa tesi è basato principalmente sullo sfruttamento dei processi termochimici in presenza di acqua supercritica per lo smaltimento dei rifiuti. Dipendentemente dalla tipologia di questi ultimi è possibile utilizzare processi diversi per scopi diversi. Nell’ottica di una completa distruzione delle componenti inquinanti presenti nel refluo è stato preso in considerazione un trattamento di ossidazione in acqua supercritica (SCWO); se invece l’obiettivo è quello di valorizzare uno scarto è possibile sfruttare il processo di gassificazione in acqua supercritica (SCWG). Dopo una breve introduzione per inquadrare il problema dei rifiuti con gli attuali metodi di trattame…
Mediterranean Coastal Lagoons Review: Sites to Visit before Disappearance
2022
Coastal lagoons are an established priority habitat in the European environment because of the biological communities that inhabit them. Their origin is related to the transport of sediments from a nearby river or the movement of sands by the marine currents that produce the closure of a gulf. Therefore, they are recent geological formations, which also disappear quickly if environmental conditions change. The 37 coastal lagoons with a surface area greater than 10 km2 located in the Mediterranean basin have been identified. Fishing has been the traditional use of these lagoons, in addition to their use as a navigation harbor when they are open to the sea. Pollution, quality problems and the…
Out-of-Plane Behavior of URM Infill: Accuracy of Available Capacity Models
2022
The aim of this paper is to check the accuracy of analytical capacity models available for the prediction of out-of-plane strength of unreinforced masonry (URM) infill walls. The accuracy of the available models is checked by detailed comparison with the existing experimental results. In doing so, both types of capacity models are evaluated: Type I for the prediction of the strength in the undamaged state, and Type II for the prediction of strength reduction in the in-plane damaged state. Results from the calculations are discussed, and the best among the available models are recommended. Furthermore, the influence of orthotropy of the infill masonry in the out-of-plane capacity predicted b…
Asymptotic and bootstrap tests for subspace dimension
2022
Most linear dimension reduction methods proposed in the literature can be formulated using an appropriate pair of scatter matrices, see e.g. Ye and Weiss (2003), Tyler et al. (2009), Bura and Yang (2011), Liski et al. (2014) and Luo and Li (2016). The eigen-decomposition of one scatter matrix with respect to another is then often used to determine the dimension of the signal subspace and to separate signal and noise parts of the data. Three popular dimension reduction methods, namely principal component analysis (PCA), fourth order blind identification (FOBI) and sliced inverse regression (SIR) are considered in detail and the first two moments of subsets of the eigenvalues are used to test…
