Detecting Functional Requirements Inconsistencies within Multi-teams Projects Framed into a Model-based Web Methodology
One of the most essential processes within the software project life cycle is the REP (Requirements
Engineering Process) because it allows specifying the software product requirements. This specification
should be as consistent as possible because it allows estimating in a suitable manner the effort required to
obtain the final product. REP is complex in itself, but this complexity is greatly increased in big, distributed
and heterogeneous projects with multiple analyst teams and high integration between functional modules.
This paper presents an approach for the systematic conciliation of functional requirements in big projects
dealing with a web model-based approach and how this approach may be implemented in the context of the
NDT (Navigational Development Techniques): a web methodology. This paper also describes the empirical
evaluation in the CALIPSOneo project by analyzing the improvements obtained with our approach.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015-71938-RED
An Extension of NDT to Model Entity Reconciliation Problems
Within the development of software systems, the development of web applications may be one of the most
widespread at present due to the great number of advantages they provide such as: multiplatform, speed of
access or the not requiring extremely powerful hardware among others. The fact that so many web applications
are being developed, makes grotesque the volume of information that it is generated daily. In the management
of all this information, it appears the entity reconciliation problem, which is to identify objects referring to
the same real-world entity. This paper proposes to give a solution to this problem through a web perspective.
To this end, the NDT methodology has been taken as a reference and has been extended adding new activities,
artefacts and documents to cover this problem.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2016-76956-C3-2-RMinisterio de Economía y Competitividad TIN2015-71938-RED
Compliance with Social Norms as an Evolutionary Stable Equilibrium
Producción CientíficaThis paper studies a two-population evolutionary game in a new setting
in between a symmetric and an asymmetric evolutionary model. It distinguishes two
types of agents: Sanchos, whose payoffs are defined by a prisoner’s dilemma game,
and Quixotes, whose payoffs are defined by a snowdrift game. Considering an imita-
tive revision protocol, a revising agent is paired with someone from his own popula-
tion or the other population. When matched, they observe payoffs, but not identities.
Thus, agents in one population interact and imitate agents from their own population
and from the other population. In this setting we prove that a unique mixed-strategy
asymptotically stable fixed point of the evolutionary dynamics exists. Taking as an
example the compliance with social norms, and depending on the parameters, two
type of equilibrium are possible, one with full compliance among Quixotes and par-
tial compliance among Sanchos, or another with partial compliance among Quixotes
and defection among Sanchos. In the former type, Sanchos comply above their Nash
equilibrium (as they imitate compliant Quixotes). In the latter type, Quixotes comply
below their Nash equilibrium (as they imitate defecting Sanchos).This study was funded by the Spanish Government (projects ECO2014- 52343-P and ECO2017-82227-P), as well as financial aid from Junta de Castilla y León (projects VA024P17 and VA105G18), co-financed by FEDER funds
Asterocheres hirsutus, a new species of parasitic copepod (Siphonostomatoida : Asterocheridae) associated with an Antarctic hexactinellid sponge
The asterocherid siphonostomatoid copepod
Asterocheres hirsutus, a new species, is described from a
hexactinellid sponge of the genus Rossella Carter collected during the Polastern cruise ANT XVII/3, off
South Shetland Islands. The distinctive features of this
new species are: a female with 21-segmented and a male
with 17-segmented antennules, praecoxal endite of
maxillule more than four times longer than palp and the
ornamentation of the posterior surface of legs 1–4. A
detailed description of both sexes is presented
A Model-Driven Approach for Business Process Management
The Business Process Management is a common mechanism recommended by a high number of standards for the management of companies and organizations. In software companies this practice is every day more accepted and companies have to assume it, if they want to be competitive. However, the effective definition of these processes and mainly their maintenance and execution are not always easy tasks. This paper presents an approach based on the Model-Driven paradigm for Business Process Management in software companies. This solution offers a suitable mechanism that was implemented successfully in different companies with a tool case named NDTQ-Framework.Ministerio de Educación y Ciencia TIN2010-20057-C03-02Junta de Andalucía TIC-578
Wikileaks y el nuevo ecosistema informativo : Wikileaks and the new informative ecosystem
nternet se ha convertido en una he
rramienta rápida y útil para divulgar
noticias de gran relevancia mundial, como
los recientes acontecimientos políticos
de Túnez y Egipto. Esa inmediatez y la
ausencia de fronteras informativas
evidencian un cambio en el Pe
riodismo Político, ya que se
pierde de vista la figura
del profesional de la información, cuyo papel de intermediario entre la realidad y el
público es asumido por el propio internau
ta, que participa en la construcción y
elaboración de los contenidos.
Con el objetivo de describir ese cambio, se realiza un estudio de caso de la web de
noticias Wikileaks, fundada en 2006 por el hacker australiano Julian Assange, que
se dedica a divulgar informes filtrados y datos confidenciales acerca de la forma de
actuar de los distintos gobiernos de todo el mundo.
El trabajo propuesto parte de un estudio documental bibliográfico sobre Wikileaks,
especialmente de la publicación de
más de 250.000 cables reservados, que
remitían las embajadas estadounidenses en
todo el mundo hacia la Secretaría de
Estado, lo que ha originado un autént
ico ‘cablegate’, un escándalo político
comparable a lo que en su día supuso el Watergate.
En la parte analítica nos decantamos por un método cualitativo no experimental,
centrándonos en los contenidos publicados en diarios digitales sobre el caso Wikileaks. Así se podrá afirmar que Assange y su web marcan un cambio en el
ecosistema informativo. Aparece una nueva forma de hacer Periodismo en la que la
labor de los periodistas de calidad parece quedar relegada a pasar la criba y situar
en contexto. El reto actual que se abre ante
el periodismo político es lograr articular
su nueva misión dentro del panorama
informativo con los tres elementos que
aportan su valor añadido: ser testigo, de
scifrar e interpretar la realidad que nos
rodea.nternet has become a quick and usef
ul tool to spread news of great
global importance, such as recent politi
cal events in Tunisia and Egypt. This
immediacy and the lack of information
borders show a change in political
journalism, because it loses sight of the information professional, whose role of
intermediary between actual reality and th
e public is assumed by the own surfer,
who participates in construction and development of contents.
In order to describe this change, it takes
a case study of website Wikileaks, founded
in 2006 by the Australian hacker Julian
Assange, devoted to disclose filtered
reports and confidential datas about the
modus operandi of
various Governments
around the world.
The proposed work starts from a documentary bibliographical study on Wikileaks,
particularly the publication of more than 250.000 confidential cables, that were
sent by American embassies around the wo
rld to the Secretary of State, which has
created a true 'cablegate', a political scandal comparable to that once marked the
Watergate.
In the analytical part we chose a qualitative not experimental method, focusing on
the content published in online newspape
rs about the Wikileaks case. So you can
say that Assange and his web make a chan
ge in the informative ecosystem. A new
way of doing journalism rises in which qu
ality journalistic work appears to be
pushed to sift out and put in context.
The current challenge opened to political
journalism is to articulate a new mission within the informative landscape with the
three elements that bring added value: to
witness, to decipher and to interpret the
reality around us
Influence of temperature and time on the Eu3+ reaction with synthetic Na-Mica-n (n = 2 and 4)
Bentonite is accepted as the best clay material for the engineered barrier of Deep Geological Repositories (DGRs). The performance of clay as the main component of the engineered barrier in the DGR has been intensively studied and the structure of the selected clay mineral play a crucial role. In this sense, a new family of synthetic swelling silicates, Na-Mica-n, with tuned layer charge (n) values between 2.0 and 4.0 per unit cell has recently been synthesized and a general synthetic method has been reported. These swelling high-charge micas could be highly valuable for the decontamination of harmful cations. The ability of these micas to immobilize Eu3+ under subcritical conditions has been probed. The adsorption was in both non-specific sites (cation exchange mechanism) and specific sites (chemical reaction or surface defects adsorption). Moreover, its adsorption capacity, under the same conditions is higher than in saponite and far superior to the bentonites.Junta de Andalucía P12-FQM-567European Union 29178
