The pricing capability lifecycle of digital innovations

2021

The pricing capability provides a basis for firms’ competitive advantage. However, to date, the literature has not investigated how this capability forms, develops, and matures. In this study, we define the pricing capability as a dynamic capability consisting of three operational building blocks (tools and data, human and relational resources, and processes, routines, and mechanisms) as well as two dynamic capability building blocks (alertness and responsiveness, and value-based strategic thinking). Furthermore, we propose the pricing capability lifecycle of digital innovations that incorporates insights of the dynamic capabilities view (DCV). Based on a longitudinal multi-case study of fi…

Preparation of Pd coated anodic alumina membranes for gas separation media

2007

Different procedures of Pd electroless deposition onto anodic alumina membranes were investigated to form a dense metal layer covering pores. The main difficulty was related to the amorphous nature of anodic alumina membranes, determining low chemical stability in solutions at pH > 9, where Pd plating works more efficiently. As a consequence, it was necessary to find the operative conditions allowing Pd deposition without damaging the membrane: to reduce alumina dissolution, the plating bath was buffered at pH 8.5 by addition of either NaHCO 3 or Na 2 B 4 O 7 ·H 2 O. Acceptable conversion of Pd was found after a deposition time of 3 min. Single and multiple deposition steps (each lasting 3 …

Roton-roton crossover in strongly correlated dipolar Bose-nonstnon condensates

2011

We study the pair correlations and excitations of a dipolar Bose gas layer. The anisotropy of the dipole-dipole interaction allows us to tune the strength of pair correlations from strong to weak perpendicular and weak to strong parallel to the layer by increasing the perpendicular trap frequency. This change is accompanied by a roton-roton crossover in the spectrum of collective excitations, from a roton caused by the head-to-tail attraction of dipoles to a roton caused by the side-by-side repulsion, while there is no roton excitation for intermediate trap frequencies. We discuss the nature of these two kinds of rotons and the relation to instabilities of dipolar Bose gases. In both regime…

Dynamic analysis for axially moving viscoelastic panels

2012

In this study, stability and dynamic behaviour of axially moving viscoelastic panels are investigated with the help of the classical modal analysis. We use the flat panel theory combined with the Kelvin–Voigt viscoelastic constitutive model, and we include the material derivative in the viscoelastic relations. Complex eigenvalues for the moving viscoelastic panel are studied with respect to the panel velocity, and the corresponding eigenfunctions are found using central finite differences. The governing equation for the transverse displacement of the panel is of fifth order in space, and thus five boundary conditions are set for the problem. The fifth condition is derived and set at the in-…

Coupled Discrete Fractional-Order Logistic Maps

2021

This paper studies a system of coupled discrete fractional-order logistic maps, modeled by Caputo’s delta fractional difference, regarding its numerical integration and chaotic dynamics. Some interesting new dynamical properties and unusual phenomena from this coupled chaotic-map system are revealed. Moreover, the coexistence of attractors, a necessary ingredient of the existence of hidden attractors, is proved and analyzed.

Speechlessness, anxiety, and confusion in a teacher education student group

2017

The aim of the study was to explore the tensions, as experienced by student teachers, in a teacher education program that is based on psychodynamic theory. Previous research shows that students have had orientation problems in innovative university studies because it involves students having to take steps toward their discomfort zone. It was therefore considered important to study the mismatch or match of the training model and student experiences. The data were gathered through student interviews. The data analysis utilized a case study methodology and proceeded from thematic network analysis toward a deeper interpretation of the data. The analysis shows students struggle to understand the…

Koordinaatio, ketteryys ja dynaaminen tasapaino suomalaisilla urheiluseurassa urheilevilla nuorilla

2016

Liikuntataitojen oppiminen on yksi liikuntakasvatuksen tärkeimmistä tavoitteista. Hyvät lii-kuntataidot auttavat liikunnallisen elämäntavan omaksumisessa ja arjessa selviytymisessä. Tämän tutkimuksen tavoitteena on tutkia suomalaisten urheiluseurassa urheilevien lasten ja nuorten koordinaatiota, ketteryyttä ja dynaamista tasapainoa KTK-testillä (Körperkoor-dinationstest für Kinder) mitattuna. Tutkimuksen aineistona käytettiin sekundaariaineistoa, jossa 8–19-vuotiaita (n=1097, poikia 364, tyttöjä 733, ka 12,58 ± 1,80 vuotta) urheiluseurassa urheilevia lapsia ja nuoria oli mitattu KTK-testillä. Aineisto kerättiin syksyn 2013 ja kevään 2014 aikana ja kyseessä on poikkileikkaustutkimus. Aineist…

How a glass-processing SME developed its big data competence

2021

This chapter demonstrates how Glaston, a glass-processing SME, has overcome the constraints of limited funds and limited technical know-how to develop its big data competence. While describing Glaston's big data journey, the study focuses on three types of dynamic capabilities that have played a crucial role in the building of Glaston's big data competence. First, the combination of market listening and business imagination has enabled Glaston to monitor technological developments in the industry and adapt them to big data use cases that are relevant for the company. Second, open innovation has allowed Glaston to complement internal resources and co-create big data initiatives with external…
