Alignment of strategy and structure in local government

2020

Strategic positioning and structural alignment in the public sector is a neglected area of research. This paper analyses the strategic positions of prospectors, defenders and reactors and structural alignment in Norwegian municipalities. Top managers responding to a survey perceived that the municipalities did align their organizational structures to the strategic positions for prospectors and defenders, but not for reactors, as hypothesized, but these relationships were modest. The top managers often found it difficult to provide consistent responses on their organizations’ choices of strategic positions. The authors show that many Norwegian municipalities have minimal alignment of their o…

Through-focus response of multifocal intraocular lenses evaluated with a spatial light modulator

2012

A new testing technique based on the use of a liquid crystal spatial light modulator (SLM) is proposed to analyze the optical quality of multifocal intraocular lenses (MIOLs). Different vergences and decentrations of the incident beam can be programmed onto the SLM in order to record the point spread function (PSF) for different object positions. From these axial PSFs, the through-focus modulation transfer function is computed. Because there are no moving parts in the experimental setup, this method is fast and versatile to assess MIOLs. Experimental results confirm the potential of the proposed method.

Exploring the opportunities and challenges of european design policy to enable innovation. The case of designscapes project

2020

Design policy for innovation and prosperity has been acknowledged and adopted globally. Existing literature on design policy usually adopts a top-down perspective to analyse the components of the design innovation system and ignores the practical needs of practitioners. Our study aims to explore potential opportunities and challenges of design policies for design-enabled innovation from a bottom-up perspective. We firstly discussed the enabling role of design in the context of design as input, output and process of innovation with emphasis on design-enabled innovation conception

A note about additive designs

Some additive 2-(v,4,lambda) designs.

On the 2-(25, 5, λ) design of zero-sum 5-sets in the Galois field GF(25)

2017

In this paper we consider the incidence structure ${\mathcal{D}}=({\mathcal{F}},{\mathcal{B}}_5^{0}),$ where ${\mathcal{F}}$ is the Galois field with $25$ elements, and ${\mathcal{B}}_5^{0}$ is the family of all $5$-subsets of $\mathcal F$ whose elements sum up to zero. It is known that ${\mathcal{D}}$ is a $2$-$(25,5,71)$ design. Here we provide two alternative, direct proofs of this result and, moreover, we prove that ${\mathcal{D}}$ is not a $3$-design. Furthermore, if ${\mathcal{B}}_5^{x}$ denotes the family of all $5$-subsets of $\mathcal F$ whose elements sum up to a given element $x \in \mathcal F,$ we also provide an alternative, direct proof that $({\mathcal{F}},{\mathcal{B}}_5^{x}…

Metodologia della ricerca sociale e politiche pubbliche

2020

In questo capitolo si passano in rasegna i principali concetti che devono essere padroneggiati dal buon valutatore delle politiche pubbliche e gli strumenti che devono far parte della sua cassetta degli attrezzi. Trattando la causazione e l'esperimento vedremo come nel campo delle scienze sociali sia necessario avvalersi di alcuni accorgimenti per disegnare una buona ricerca valutativa. In this chapter we review the main concepts that must be mastered by the good public policy evaluator and the tools that must be part of his toolbox. In dealing with causation and experiment we will see how in the field of social sciences it is necessary to use some precautions to design good evaluative rese…

Study design of Heart failure Events reduction with Remote Monitoring and eHealth Support (HERMeS)

2020

Aims: The role of non‐invasive telemedicine (TM) combining telemonitoring and teleintervention by videoconference (VC) in patients recently admitted due to heart failure (HF) (‘vulnerable phase’ HF patients) is not well established. The aim of the Heart failure Events reduction with Remote Monitoring and eHealth Support (HERMeS) trial is to assess the impact on clinical outcomes of implementing a TM service based on mobile health (mHealth), which includes remote daily monitoring of biometric data and symptom reporting (telemonitoring) combined with VC structured, nurse‐based follow‐up (teleintervention). The results will be compared with those of the comprehensive HF usual care (UC) strateg…

Understanding Situational Disabilities and Situational Awareness in Disasters

2019

In this paper, a scenario-based approach augmented with personas typically used in universal design and interactive design domains is used to illustrate the occurrence of situational disabilities in emergency situations, and to show how environmental factors can trigger these situational disabilities. With the help of personas representing selected archetypical characteristics and roles, the scenarios are further examined to show how these situational disabilities can affect the situational awareness of different stakeholders, not only in the command and control centers, but also first responders in the field as well as affected members of the public. This approach provides a better underst…

Magnetic domain-wall racetrack memory for high density and fast data storage

2012

The racetrack memory device is a new concept of Magnetic RAM (MRAM) based on controlling domain wall (DW) motion in ferromagnetic nanowires. It promises ultra-high storage density thanks to the possibility to store multiple narrow DWS per memory cell. By using read and write heads based on magnetic tunnel junctions (MTJ) with perpendicular magnetic anisotropy (PMA) fast data access speed can also be achieved. Thereby the racetrack memory can be used as universal storage to address both embedded and standalone applications. In this paper, we present the device physics, integration circuit and architecture designs of a racetrack memory based on MTJs with PMA. Mixed SPICE simulations at 65 nm …
