Value networks in cloud computing

2011

PurposeThe purpose of this paper is to examine value networks in cloud computing. It demonstrates the kinds of value offered by such networks to firms within a given network, and considers how and why the network may change over time.Design/methodology/approachThe paper reports on a longitudinal case study, including a total of seven semi‐structured open‐ended interviews, conducted with five informants from the case firm.FindingsIt was found that cooperation in value networks provides not merely financial benefits, but also knowledge, among other intangible benefits. Value networks should be evaluated as a whole, since there may be indirect connections – i.e. the value comes not directly fr…

Exploring the cross-linguistic transfer of reading skills in Spanish to English in the context of a computer adaptive reading intervention

2017

ABSTRACTWe explore the potential of a computer-adaptive decoding game in Spanish to increase the decoding skills and oral reading fluency in Spanish and English of bilingual students. Participants were 78 first-grade Spanish-speaking students attending bilingual programs in five classrooms in Texas. Classrooms were randomly assigned to the treatment (i.e., where students played Graphogame Spanish) for 16 weeks for ten minutes per day (n = 3) versus business as usual instruction (n = 2). Results indicate that students at some risk on Spanish pseudoword reading appeared to benefit the most from playing the game. Analysis of gains suggests a potentially small, but meaningful educational effect…

Hippocampal ripple-contingent training accelerates trace eyeblink conditioning and retards extinction in rabbits.

2010

There are at least two distinct oscillatory states of the hippocampus that are related to distinct behavioral patterns. Theta (4–12 Hz) oscillation has been suggested to indicate selective attention during which the animal concentrates on some features of the environment while suppressing reactivity to others. In contrast, sharp-wave ripples (∼200 Hz) can be seen in a state in which the hippocampus is at its most responsive to any kind of afferent stimulation. In addition, external stimulation tends to evoke and reset theta oscillation, the phase of which has been shown to modulate synaptic plasticity in the hippocampus. Theoretically, training on a hippocampus-dependent learning task conti…

Solution of universal nonrelativistic nuclear DFT equations in the Cartesian deformed harmonic-oscillator basis. (IX) HFODD (v3.06h) : a new version …

2021

We describe the new version (v3.06h) of the code HFODD that solves the universal nonrelativistic nuclear DFT Hartree-Fock or Hartree-Fock-Bogolyubov problem by using the Cartesian deformed harmonic-oscillator basis. In the new version, we implemented the following new features: (i) zero-range three- and four-body central terms, (ii) zero-range three-body gradient terms, (iii) zero-range tensor terms, (iv) zero-range isospin-breaking terms, (v) finite-range higher-order regularized terms, (vi) finite-range separable terms, (vii) zero-range two-body pairing terms, (viii) multi-quasiparticle blocking, (ix) Pfaffian overlaps, (x) particle-number and parity symmetry restoration, (xi) axializatio…

Anthropomorphism and social presence in Human–Virtual service assistant interactions: The role of dialog length and attitudes

2022

In this study, we delve into the perceived quality of recommendations provided by AI-based virtual service assistants (VSAs). Specifically, the role of the social presence of VSAs in influencing recommendation perceptions is investigated. We also explore how the social presence of a VSA is formed and how perceived anthropomorphism plays a vital role in shaping social presence and eventually instilling trust in VSAs among consumers. These relationships are examined in the context of online government services. The results indicate that consumer interaction with VSAs - manifesting via perceived anthropomorphism, social presence, dialog length, and attitudes - improves recommendation quality p…

2010

Nykymaailmassa vieraan kielen hyvää ääntämistä pidetään olennaisena osana kielitaitoa ja kommunikatiivista kompetenssia. Näin myös ääntämisen opettamisesta on tullut yhä merkittävämpi osa vieraan kielen opetusta. Tietotekniikka sovelluksineen on vallannut alaa yhteiskuntamme eri osa-alueilla ja myös kouluissa ollaan vähitellen alettu käyttää tietokoneita apuna ja työvälineinä opetuksessa. Kieltenopetuksessa tietokoneet ja erityisesti internet tuovat vieraat kielet kulttuuripiireineen luokkahuoneeseen tarjoten rajattomasti mahdollisuuksia oppia kielistä ja kulttuureista, käyttää autenttisia materiaaleja ja kommunikoida reaaliajassa sekä muiden kieltenopiskelijoiden että natiivien kanssa. Eri…

Learner-generated drawings in physics education

2013

Different kinds of visual representations, such as graphs and drawings are important in education but especially in science education. Little attention is paid especially to drawings. Students are required to examine drawings and assimilate the information conveyed by them but not much attention is paid to the students’ own drawings. Arguments can be made for the importance of learner-generated drawings in science education. The subject of this thesis is the use of learner-generated drawings in physics education. A study was conducted to study the use of learner-generated drawings as a tool for meaning-making. The study involved 36 upper secondary school students who were given a drawing as…

Torus computed tomography

2020

We present a new computed tomography (CT) method for inverting the Radon transform in 2D. The idea relies on the geometry of the flat torus, hence we call the new method Torus CT. We prove new inversion formulas for integrable functions, solve a minimization problem associated to Tikhonov regularization in Sobolev spaces and prove that the solution operator provides an admissible regularization strategy with a quantitative stability estimate. This regularization is a simple post-processing low-pass filter for the Fourier series of a phantom. We also study the adjoint and the normal operator of the X-ray transform on the flat torus. The X-ray transform is unitary on the flat torus. We have i…

A computer‐based Pinyin intervention for disadvantaged children in China : Effects on Pinyin skills, phonological awareness, and character reading

2020

Pinyin is an alphabetic script that denotes pronunciations of Chinese characters. Studies have shown that Pinyin instruction enhances both phonological awareness (e.g., Shu et al., Developmental Science, 2008, 11, 171–181) and character reading (e.g., Lin et al., Psychological Science, 2010, 21, 1117–1122) in Chinese children. In the present study, we provided a 3‐week Pinyin intervention with a computer‐based Pinyin GraphoGame to disadvantaged migrant children with poor Pinyin skills. A total of 252 first graders who were children of migrant workers in a large Chinese city were assessed to identify poor Pinyin readers. Fifty‐six 7‐year‐old children with poor Pinyin skills were selected and…
