“I do those things to pass the time.”: Active ageing during fourth age
2021
Active ageing is a dominant but disputed discourse in the field of ageing. Since it is usually associated with the third age, this article will focus on the active ageing of older adults who need care and services, who are known as the fourth agers. Our data consists of interviews collected from 16 older adults. We analysed the data through content analysis that was guided by the Active Ageing Index (AAI) that is a measuring tool concerning active ageing. According to our results, active ageing during the fourth age can be understood through the lens of small actions and precarity. Although some actions had to be given up or modified, participants were active in various ways, and help from …
Oscillation of fourth-order quasilinear differential equations
2015
We study oscillatory behavior of a class of fourth-order quasilinear differential equations without imposing restrictive conditions on the deviated argument. This allows applications to functional differential equations with delayed and advanced arguments, and not only these. New theorems are based on a thorough analysis of possible behavior of nonoscillatory solutions; they complement and improve a number of results reported in the literature. Three illustrative examples are presented.
Campaigning in the fourth age of political communication. A multi-method study on the use of Facebook by German and Austrian parties in the 2013 nati…

Starting from the contribution to the discussion on a fourth age of political communication, here we argue that, as a consequence of how the Web 2.0 has changed political campaigns, the theoretical...
On regularity up to the boundary of solutions to a system of degenerate nonlinear elliptic fourth-order equations
2008
Under some hypotheses on weighted functions, using the interior regularity results established in (Kovalevsky, A. and Nicolosi, F., 2005, Existence and regularity of solutions to a system of degenerate nonlinear fourth-order equations. Nonlinear Analysis, 61, 281–307) and estimating the oscillation of solutions near the boundary of Ω, we establish results on regularity up to the boundary of a solutions of the system (1.1).
Introduction to the GiNaC Framework for Symbolic Computation within the C++ Programming Language
2002
AbstractThe traditional split into a low level language and a high level language in the design of computer algebra systems may become obsolete with the advent of more versatile computer languages. We describe GiNaC, a special-purpose system that deliberately denies the need for such a distinction. It is entirely written in C++and the user can interact with it directly in that language. It was designed to provide efficient handling of multivariate polynomials, algebras and special functions that are needed for loop calculations in theoretical quantum field theory. It also bears some potential to become a more general purpose symbolic package.
Examination of the fetal brain by transabdominal three-dimensional ultrasound: potential for routine neurosonographic studies
2006
Objective To evaluate the role of transabdominal three-dimensional (3D) ultrasound in the assessment of the fetal brain and its potential for routine neurosonographic studies. Methods We studied prospectively 202 consecutive fetuses between 16 and 24 weeks' gestation. A 3D ultrasound volume of the fetal head was acquired transabdominally. The entire brain anatomy was later analyzed using the multiplanar images by a sonologist who was expert in neonatal cranial sonography. The quality of the conventional planes obtained (coronal, sagittal and axial, at different levels) and the ability of the 3D multiplanar neuroscan to visualize properly the major anatomical structures of the brain were eva…
¿La vuelta a los dos demonios? Cine y pasado reciente en Argentina: una lectura actual / The Return to the theory of two demons? Cinema and Recent Pa…
2016
Este artículo indaga acerca de los tres “momentos de la memoria” (Zarco, 2016: 12-13), entendiendo con ello, el espacio, la puesta en agenda, la visibilidad, los límites y los alcances que los diferentes gobiernos han otorgado a la reconstrucción del pasado reciente argentino. Dependiendo de la estrategia memorística propuesta por cada gobierno, el cine tendrá mayor o menor apoyo estatal, implicando ello una mayor o menor repercusión de público. Para abordar las políticas de la memoria del actual gobierno argentino, se indaga acerca de lo que hemos denominado el cuarto momento de la memoria, “Vuelta a los dos demonios (2016-)” en el que se evidencia un regreso a la “teoría de los dos demoni…
Breaking the “Fourth Wall” in Qualitative Research: Participant-Led Digital Data Construction
2018
This article reconstructs the typical researcher-participant focus - where the participants are doing for us - instead we followed the participants’ lead in the construction of research. Using a qualitative literacy event case study as an example, we describe how participants unexpectedly co-constructed knowledge through a participant-led digital data collection. In this theoretical article, we provide an explanation of the original study, which used observations, semi-structured interviews, and home visits as a collective qualitative case study on parental participation in social literacy practices. The original investigation led to the important shift that occurred in participant-research…
A note on the packing of two copies of some trees into their third power
2003
Abstract It is proved in [1] that if a tree T of order n is not a star, then there exists an edge-disjoint placement of two copies of this tree into its fourth power. In this paper, we prove the packing of some trees into their third power.
Automated source code transformations on fourth generation languages
2004
To control the operation of large application suites or to tailor a special purpose application to particular need, developers frequently use application specific languages, such as batch, scripting, and query languages. These languages which are also referred to as fourth generation languages (4GLs) therefore play an important role in today's economy. Incompatibilities between different versions of 4GLs and changing requirements may make massive changes on a company's library of 4GL programs necessary. Here, we explore possibilities for performing mass changes on 4GLs and show how the transformation of programs written in 4GLs compares to the transformation of mainstream programming langua…
