School adjustment in children who stutter: The quality of the student-teacher relationship, peer relationships, and children's academic and behaviora…
2020
Abstract Introduction The aim of this study was to investigate the quality of the student-teacher relationship, peer relationship, emotional and behavioral outcomes and academic performance in school adjustment of children who stutter. Methods The convenience sample consisted of 536 children – 62 affected by stuttering and 474 in the control group – and 36 prevalent teachers from six primary and secondary schools in Northwest Italy. Children were assessed with a sociometric questionnaire. Teacher evaluations were also used to assess their perception of their relationships with the student (Student-Teacher Relationship Scale), children’ behavior (Strengths and Difficulties Questionnaire), an…
On the category Set(JCPos)
2006
Category Set(JCPos) of lattice-valued subsets of sets is introduced and studied. We prove that it is topological over SetxJCPos and show its ''natural'' coalgebraic subcategory.
Nörttikulttuurin identiteettikriisi
2020
Nörttikulttuuri on identiteettikriisissä. Perinteisesti nörttimäisinä pidetyt käytänteet ja kulttuurituotteet ovat siirtyneet lähemmäs valtavirtaa, mikä on häivyttänyt rajaa nörttien ja muiden median ja teknologian käyttäjien välillä. Nörttikulttuurin sisälle tämä on heijastunut kiistaksi siitä, kuka saa osallistua nörttikulttuurin kuluttamiseen, tuottamiseen ja määrittelyyn, ja millä tavoin. Stereotypia nörttikulttuurista valkoisten heteromiesten maskuliinisena kenttänä ei koskaan ole pitänyt täysin paikkansa, mutta 2000-luvulla väitteen totuudellisuus on murentunut entisestään.
 Tässä artikkelissa tarkastelemme nörttiyden kriisiä kolmen tapaustutkimuksen kautta ja analysoimme, mitä G…
Impact of reverse logistics on supply chain performance
2013
Purpose – The purpose of this paper is to analyse the impact of reverse logistics on order and inventory variance amplification in a single-echelon supply chain (SC) and to propose a new order policy for dampening such amplification. Design/methodology/approach – A general review of the literature on sustainable operations and on the impact of reverse logistics on SC performance provides the foundation for the study. The authors use difference equation math approach for modelling and analysing a closed SC. A proper design of experiment and data collected from the European Union statistics validate the obtained numerical results. Findings – The variability of reverse flow in a closed loop S…
Appendix: Diophantine Approximation on Hyperbolic Surfaces
2002
In this (independent) appendix, we study the Diophantine approximation properties for the particular case of the cusped hyperbolic surfaces, in the spirit of Sect. 2 (or [11]), and the many still open questions that arise for them. We refer to [9], [10]for fundamental results and further developments. We study in particular the distance to a cusp of closed geodesics on a hyperbolic surface.
Closed Form Approximation of Swap Exposures
2013
This paper provides closed form lower and upper bounds for the price of European swaption on cross currency basis swap with the presence of dynamic basis spreads. Cross currency basis spreads are treated as integrals of spot spreads, approach familiar from interest rate models. The spot spread is modelled by two-factor mean reverting Gaussian model that is equivalent to two-factor Hull-White model introduced by [Hull and White(1994)]. This model allows closed form approximations and relatively well fitting and simple calibration to the spread term structure.
Optical counterpart to Swift J0243.6+6124
2020
Context. Swift J0243.6+6124 is a unique system. It is the first and only ultra-luminous X-ray source in our Galaxy. It is the first and only high-mass Be X-ray pulsar showing radio jet emission. It was discovered during a giant X-ray outburst in October 2017. While there are numerous studies in the X-ray band, very little is known about the optical counterpart. Aims. Our aim is to characterize the variability timescales in the optical and infrared bands in order to understand the nature of this intriguing system. Methods. We performed optical spectroscopic observations to determine the spectral type. Long-term photometric light curves together with the equivalent width of the Hα line were u…
Automatic orientation and 3D modelling from markerless rock art imagery
2013
This paper investigates the use of two detectors and descriptors on image pyramids for automatic image orientation and generation of 3D models. The detectors and descriptors replace manual measurements and are used to detect, extract and match features across multiple imagery. The Scale-Invariant Feature Transform (SIFT) and the Speeded Up Robust Features (SURF) will be assessed based on speed, number of features, matched features, and precision in image and object space depending on the adopted hierarchical matching scheme. The influence of applying in addition Area Based Matching (ABM) with normalised cross-correlation (NCC) and least squares matching (LSM) is also investigated. The pipel…
Henkilöhahmon sisäinen konflikti Väinö Linnan romaanissa Tuntematon sotilas
2015
The object of this study is character´s internal conflict in the novel. The primary research question is: What are the internal conflicts of characters like in Väinö Linna’s novel The Unknown Soldier? An answer to the primary research question is sought by answering the following secondary research questions: What are the specific internal conflicts like? How do they manifest? What are the most important effects they have on the structure of the narrative? What kinds of groups of characters are possible to form? How could the traditional notion of characters internal conflict, as it is traditionally defined in literary studies, be developed? In this study, internal conflict takes place when…
Integrazione di celle fotovoltaiche ibride nel vetromattone
2012
L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…
