Understanding Economic Growth in Ghana in Comparative Perspective
2019
Ghana has experienced a decade of solid and exceptionally high growth. Between 2005 and 2015, income nearly doubled. This paper analyzes the factors driving this impressive growth performance, using tools such as structural change decompositions and growth regressions. For the comparative perspective, the paper compares Ghana with its structural and aspirational peers. The paper finds that the contribution of structural change to growth has been limited and attributes this to labor that was freed up in agriculture not being absorbed by high-productivity sectors. Looking at factors that drove growth since 2000, financial development and infrastructure had the most important impacts. A benchm…
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 …
Entstehen und Scheitern Strategischer Allianzen in der Telekommunikationsbranche
2001
Hungenberg (1998) has shown in this journal that strategic alliances have become an important strategic instrument in the telecommunications industry. Building up on this investigation we analyze the motives for the formation and failure of strategic alliances on the basis of a content analysis of the business newspaper “Handelsblatt” from 1995–1997. We show that in the telecommunications sector access to know-how and other resources as well as market access are the primary motives for the formation of strategic alliances. In contrast to other industries, cost and time advantages as motives are not relevant at all. The primary reason for the failure of strategic alliances was strategic reor…
ViSPE: A Graphical Policy Editor for XACML
2015
In this paper we present the Visual Security Policy Editor (ViSPE), a policy-maker-friendly graphical editor for the eXtensible Access Control Markup Language (XACML). The editor is based on the programming language Scratch and implemented in Smalltalk. It uses a graphical block-based syntax for declaring access control polices that simplifies many of the cumbersome and verbose parts of XACML. Using a graphical language allows the editor to aid the policy-maker in building polices by providing visual feedback and by grouping blocks and operators that fit together and also indicating which blocks that stick together. It simplifies building policies while still maintaining the basic structure…
Methods for defining user groups and user-adjusted information structures
1999
A common problem in the design of information systems is how to structure the information in a way that is most useful to different groups of users. This paper describes some statistical methods for revealing the structure inherent in empirical data elicited from users. It is illustrated by the application of these methods to the design of some web pages giving information about the Universitat de Valencia. Three potential user groups were identified, administrative staff, teaching staff and students. The first analysis demonstrated that users within these three groups assign relatively homogeneous structures, but that the structures assigned by the three groups are not the same, and also, …
Accuracy of Computer-Aided Dynamic Navigation Compared to Computer-Aided Static Procedure for Endodontic Access Cavities: An In Vitro Study
2020
: Purpose: To analyze the accuracy of two computer-aided navigation techniques to guide the performance of endodontic access cavities compared with the conventional access procedure. Materials and Methods: A total of 30 single-rooted anterior teeth were selected, which were randomly distributed into three study groups: Group A&mdash
Public availability of published research data in substance abuse journals
2014
[EN] Sharing research data is an increasingly necessary requirement for the advancement of science. The aim of this study was to analyse the policies on openness in sharing scientific research data in substance abuse journals. Journals included in the Substance abuse area of the Journal Citation Reports were used for the analysis, with reference to the instructions to authors published on the journals websites. In 67.6% of the journals, it is possible to store materials in thematic or institutional repositories; 47% accept supplemental material; 64.7% allow the reuse of data, and 41.2% admit the publication of their data on a website. Most journals recommend that authors deposit their data …
Accessible film festivals: a pilot study
2020
This work provides an overview of the state of accessibility at film festivals all over the world, identifies its selected audiences and also encourages innovative solutions in relation to linguistic and technical issues emerged during the processes of subtitling. The outbreak of the Covid-19 pandemic in 2020 has resulted in many film festivals all over the world being either cancelled, postponed or moved to online platforms. What has arisen is the question whether and to what extent people with sensorial disabilities, in particular deaf and hard-of-hearing and blind and visually impaired people, have been left behind or have been part of projects of inclusion. The accessibility of forms of…
Audiovisual accessibility on the web: subtitling in the European Parliament
2020
El presente trabajo pone de relevancia la importancia de la accesibilidad en la sociedad de la información actual, en concreto, en Internet, por lo que analizaremos el cumplimiento de los requisitos de accesibilidad a los contenidos audiovisuales establecidos por las Pautas de Accesibilidad al Contenido Web (WCAG) 2.0 en el canal de televisión online EuroparlTV. Asimismo, trazaremos el vínculo inherente entre la accesibilidad web y la audiovisual y describiremos los subtítulos generados por profesionales de la traducción en el ámbito institucional, concretamente en el Parlamento Europeo. Para llevar a cabo nuestro objetivo y poder realizar el estudio sistemático y exhaustivo de distintos as…
Accessibilità e uso sostenibile del patrimonio architettonico. Superuser e baukultur per un rinnovamento metodologico
2021
L’accessibilità nel patrimonio architettonico, tema dibattuto da decenni, si è evoluto negli orientamenti culturali, nella legislazione e normativa tecnica e nelle realizzazioni. L’argomento tocca questioni complesse e mutevoli: aspetti materiali e immateriali; fattori demografici e socio-economici; usi (praticati e auspicati) da parte di persone dalle differenti capacità motorie, intellettive, cognitive ed emotive; valori e significati che ogni generazione tende ad attribuire al patrimonio culturale. Dopo aver collegato l’accessibilità agli avanzamenti sull’uso del patrimonio, il contributo descrive il progressivo ampliamento qualitativo e quantitativo di questo requisito. La varietà e vas…
