Hermeneutical Engineering of Requirements  [PDF]
Wagner Varalda, ítalo S. Vega
Journal of Computer and Communications (JCC) , 2017, DOI: 10.4236/jcc.2017.52002
Abstract: The Software Engineering aims to develop, within the deadlines and costs established, quality software and that meets the needs of its users. To be made the definition of what the software should do (to establish its purpose), it included the execution of activity the Requirements Engineering, where the context of software to be developed is identified, examined and specified. All other activities of software development depend primarily on this activity. However, there is a problem increasingly in evidence: understand the context of software to be developed. This article aims to present a proposal to face this problem through the use of specific hermeneutical methods for the Requirements Engineering, which will help the software development team understand the original needs of the business to be attended. The basic idea is to produce a hermeneutic specification acceptable, which will be used for the extraction and the specification of the software requirements to be developed. In essence, the hermeneutics focuses on the true interpretation and understanding in contextualized of what is intended to know. The Hermeneutical Engineering of Requirements comes to be the result of the adequacy of methods hermeneutical to assist, specifically the activity of Engineering of Requirements.
Hermeneutical Theodolite of Requirements: Evaluating and Revealing the Quality Grades of Software Requirements and of Domain of Application  [PDF]
Wagner Varalda, ítalo Santiago Vega
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.65004
Abstract: Throughout the development of software, during Requirements Engineering activities, software requirements dynamically and constantly evolve and mature from an “identified” stage to an “approved” stage. This evolution takes place individually for each requirement, in a very particular way, because it depends on the level of understanding that the requirements engineer reaches in relation to it. How, then, to monitor the evolution of each software requirement? How to know the quality of each software requirement? How to measure the level of understanding and difficulty that the requirements engineer has in relation to each software requirement? This paper aims to present a proposal to answer these questions through the use of an instrument developed specifically to assess and reveal the quality grades of each software requirement and also to assess and reveal that the levels of understanding and of difficulty of the requirements engineer is in relation to each software requirement. This instrument was called the Hermeneutical Theodolite of Requirements, which also can be applied to evaluate that the levels of understanding and of difficulty of the requirements engineer is in relation to the domain of application, essential input artifact and primordial to the specification of the requirements of software.
Hermeneutical Elicitation of Requirements: A Technical Perspective to Improve the Conception of the Software Requirements  [PDF]
Wagner Varalda, ítalo Santiago Vega
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.69010
Abstract: In order to develop quality software that meets the originals needs of its users, it is necessary to perform the Requirements Engineering, so that the software context to be developed is identified, examined and specified properly. However, there is a problem that is increasingly in debate: the difficulty in understanding and establishing the purpose of the software to be developed, as pointed out by important researches in the area, such as the Chaos Report, which indicates that only 29% of software projects are successful, and the Software Engineering Institute, which points out software requirements as a critical factor for the success of software engineering and that deficiencies in this dimension are the main causes of software project failures. This article presents a proposal to address this problem through the use of the Hermeneutical Elicitation of Requirements, which is the conceptual adequacy of some hermeneutical methods in a technical approach that assists the requirements engineer to conceive better of the software requirements. In this way, the software engineer will be better able to develop the software to better meet the needs of its end users and sponsors.
When Commitment Is Not Enough: How Stress and Individual-Organization Interface Affect Activists’ Persistence  [PDF]
Terri Mannarini, Cosimo Talo
Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.25070
Abstract: In light of collective action and community development research, this study aims at testing a model of activist persistence that takes into account both individual and organizational levels. The proposed model predicted that commitment to a group/organization or its cause does affect an activists’ persistence. This relationship is mediated by two variables, namely the individual-organization interface and stress management processes. The model was empirically tested through a path analysis on a sample of 278 (N = 278; 43.9% female) participants recruited among active members in a variety of community groups/organizations. The results supported the pattern described by the model, showing that commitment is a precursor to activists’ persistence. However its direct impact is weaker than the impact exerted by stress levels and the fit between the individual and the group/organization. Applications for community development practice are discussed.
Anonymous Processors with Synchronous Shared Memory
Bogdan S. Chlebus,Gianluca De Marco,Muhammed Talo
Computer Science , 2015,
Abstract: We investigate anonymous processors computing in a synchronous manner and communicating via read-write shared memory. This system is known as a parallel random access machine (PRAM). It is parameterized by a number of processors~$n$ and a number of shared memory cells. We consider the problem of assigning unique integer names from the interval $[1,n]$ to all $n$ processors of a PRAM. We develop algorithms for each of the eight specific cases determined by which of the following independent properties hold: (1) concurrently attempting to write distinct values into the same memory cell either is allowed or not, (2) the number of shared variables either is unlimited or it is a constant independent of $n$, and (3) the number of processors~$n$ either is known or it is unknown. Our algorithms terminate almost surely, they are Las Vegas when $n$ is known, they are Monte Carlo when $n$ is unknown, and they always use the $O(n\log n)$ expected number of random bits. We show lower bounds on time, depending on whether the amounts of shared memory are constant or unlimited. In view of these lower bounds, all the Las Vegas algorithms we develop are asymptotically optimal with respect to their expected time, as determined by the available shared memory. Our Monte Carlo algorithms are correct with probabilities that are $1-n^{-\Omega(1)}$, which is best possible when terminating almost surely and using $O(n\log n)$ random bits.
Contracuerpo: reescritura de la mano junto al muro y arco secreto
Sánchez Vega,Rosaura;
Letras , 2009,
Abstract: the aim of this study is to examine the story ?contracuerpo? (counterbody) (1988) of wilfredo machado, the process of rewriting of ?arco secreto? (secret arch) (1947) of gustavo díaz solís and ?la mano junto al muro? (the hand by the wall) (1951) of guillermo meneses. also, we aim at analyzing the characteristic features of narrative of the 1080s that are present in the text. on the basis of literary theorists a diversity of re-writing processes are discussed: verbal repetition, repetition and difference, digressions, second formulation of devices, story and characters. in the light of post modernity theorists and other critics, argumentations about postmodern trends and other textual traits of the story are reinforced. as a conclusion, the meanings in ?contracuerpo? derive from re-writing: as it refers the reader to previous texts and joins a new narrative contexture with its own nature, it induces the effect of continuity between the preceding short story and that of the 1980s.
El "estado de excepción" de la filosofía
Vega Encabo,Jesús;
An??lisis filos?3fico , 2010,
Abstract: how to think today about the nature and value of the philosophical reflection? the pervasive influence of the model of expert knowledge seems to require a selfunderstanding of philosophy as a discipline among the disciplines. this paper argues that philosophy should resist this move. so i will defend a kind of "exceptionalism" for philosophy based on the idea that philosophy cannot pretend to be a discipline. be true or not that philosophical activities are nowadays institutionally legitimized by the principles of a canon, i will suggest a strategy of transgression of the canon by rejecting any assimilation of philosophy to a discipline, even if an "anomalous" one. philosophy must contribute to the understanding of our different ways of conceptualizing and transforming the world and to make sense of human experience. the thesis of this paper is that philosophy must claim a "state of emergency" for itself a open a space for freely questioning what it appears as obvious and unchallengeable.
"Traslación" y adaptación de técnicas: Tecnologías apropiadas y procesos de transferencia
Encabo,Jesús Vega;
Revista iberoamericana de ciencia tecnolog?-a y sociedad , 2004,
Abstract: the present article characterizes the processes of technical transfer using the concept of "translation", a term that allows to focus the analysis on the adaptative transformation of the technique in the new context to which it is transferred. from this point of view, the spreading and transfer of techniques could be conceived as cultural transmission processes, which set in a central position the technical abilities and the universe of cultural values that will frame the usage of the translated technology. later, the author reflects about concrete processes of technical translation, especially those referred to developing countries, and carefully analyzing the idea of "appropriate (or convenient) technology". the idea, arose as an attempt to find adequate criteria for the translation of techniques to other contexts, sets the stage for introducing factors internal to the technique design (such as effectiveness and feasibility), and elements that are external (such as the evaluation of its fitness or sustainability). criteria have to be universally conceived, though they are applied according to contextual factors.
Falla renal aguda por fenazopiridina: Report of one case
Vega S.,Jorge;
Revista médica de Chile , 2003, DOI: 10.4067/S0034-98872003000500010
Abstract: a 27 years old woman was admitted due to abdominal cramps, jaundice and oligoanuria, starting 48 hours after eating chinese food. hepatic biochemical tests, abdominal ultrasound and retrograde pyelography were normal. the urine was intensely orange colored and microscopic analysis was normal. the serum creatinine and urea nitrogen on admission were 4.59 and 42.5 mg/dl and rose to 13.5 and 72.4 mg/dl, respectively, at the 6th hospital day. oliguria lasted only 48 hours. dialysis was not used, since the patient was in good general condition and uremic symptoms were absent. on the 7th day, azotemia began to subside and at the 14th day, serum creatinine was 1.0 mg/dl. before hospital discharge, she confessed the ingestion of 2.000 mg of phenazopyridine, during a nervous breakdown, aiming to sleep deeply. remarkable was the persistence of the orange color of her urine during several days and the dissociation between the rate of increase of serum creatinine with respect to urea nitrogen. this is an unusual case of acute renal failure caused by an overdose of a drug, commonly prescribed for urinary tract infections (rev méd chile 2003; 131: 541-4).
