Two Types of pseudo-clefts?
2010
Sentences such as 'What Fred does is complain' and 'What Fred does is important' have both been labeled as pseudo-clefts, though of two distinct types. We provide four tests to structurally distinguish such constructions. Entailment patterns and a number of structural ties between the post-copular constituent and specific constituents of the pre-copular relative clause suggest using the label ‘pseudo-cleft’ for the former type only. This paper also examines certain cases of pseudo-clefts with no simple correlates, and vice versa, to argue – contra Higgins 1973 – that these do not necessarily contradict the existence of a structural connection (a transformation, in the sense of Z. S. Harris)…
Requirements elicitation methods based on interviews in comparison: A family of experiments
2020
Abstract Context There are several methods to elicit requirements through interviews between an end-user and a team of software developers. The choice of the best method in this context is usually on subjective developers’ preferences instead of objective reasons. There is a lack of empirical evaluations of methods to elicit requirements that help developers to choose the most suitable one. Objective This paper designs and conducts a family of experiments to compare three methods to elicit requirements: Unstructured Interviews, where there is no specific protocol or artifacts; Joint Application Design (JAD), where each member of the development team has a specific role; Paper Prototyping, w…
Are requirements elicitation sessions influenced by participants' gender? An empirical experiment
2021
[EN] Context: Requirements elicitation is a crucial phase in the software development life cycle. During requirements elicitation sessions, requirements engineers capture software requirements, and motivate stakeholders to express needs and expected software functionalities. In this context, there is a lack of extensive empirical research reporting the extent to which elicitation sessions can be influenced by participants' gender. Objective: This paper presents our research endeavour to investigate requirements engineers' effort and elicited requirements' accuracy based on participants' gender. Method: We conducted an experiment in two rounds with a total of 59 students who played the role …
A Conceptual Model of Product Design
2013
The paper presents a conceptual model that pursues the understanding of the activities, the phases and the mechanisms of product design. The purpose of this model is to aid the product conception phase, as well as to develop software products that can furthermore aid design. The model takes into account the entire mental potential of the human being. The paper uses Jung's model in order to describe the various aspects of the human psyche. The paper presents a number of design models from the scientific literature. The proposed model defines domains of the needs imposed by stakeholders and specialists, functions domains and product domains. It explains the mechanism through which information…
The culture of product development in student organisations
2021
Product development in a multidisciplinary student organisation brings many challenges; varyingexperience, adaptation and involvement of members. This article will discuss how a multidisciplinarystudent project maintains a learning culture for product development and project management.The identified factors for a learning culture; 1) define product specifications, 2) involvealumnis, 3) facilitate an open minded culture for failure and learning and 4) collect experience andadapt an agile framework suitable for the project. These are factors that should be an implementedpart to increase the chances of maintaining a learning culture.Align Racing UiA, the case of this study, is a student organ…
An inductive learning perspective on automated generation of feature models from given product specifications
2018
For explicit representation of commonality and variability of a product line, a feature model is mostly used. An open question is how a feature model can be inductively learned in an automated way from a limited number of given product specifications in terms of features.We propose to address this problem through machine learning, more precisely inductive generalization from examples. However, no counter-examples are assumed to exist. Basically, a feature model needs to be complete with respect to all the given example specifications. First results indicate the feasibility of this approach, even for generating hierarchies, but many open challenges remain.
Including Covariates in the ETAS Model Triggered Seismicity
2020
The paper proposes a stochastic process that improves the assessment of seismic events in space and time, considering a contagion model (branching process) within a regression-like framework to take covariates into account. The proposed approach develops the Forward Likelihood for prediction (FLP) method for estimating the ETAS model, including covariates in the model specification of the epidemic component. A simulation study is carried out for analysing the misspecification model effect under several scenarios. Also an application to the Italian catalogue is reported, together with the reference to the developed R package.
A framework for intention-driven requirements engineering of innovative software products
2011
Requirements engineering is highly challenging particularly when designing innovative software products. This is so because there are no corresponding products, ultimate needs of actors are difficult to capture, the products may have unforeseeable impacts on the actors’ behavior, and it is hard to find out how value-added and competitive the product actually is. In this paper, we propose a novel framework for intention-driven requirements engineering of innovative software products, which combines technological, social and business viewpoints. We illustrate its use with a short example related to the domain of web mapping services and augmented reality. peerReviewed
Allowing End-Users to Actively Participate within the Elicitation of Pervasive System Requirements through Immediate Visualization
2009
Efficient requirements engineering activities are essential in order to develop software systems that properly satisfy end-user needs. End-users lack knowledge about requirements engineering techniques or computation in general, and it is very important that they actively participate in the requirements elicitation process because they are the "owners" of the problem. In this paper, we present a tool-supported requirements elicitation technique that is centered on end-users and that allows them to describe the main characteristics of pervasive systems. In addition, we provide end-users with an immediate natural visualization of the described requirements. Furthermore, we present a requireme…
An analytical study of the ageostrophic motion of an air parcel
1978
The complete ageostrophic motion of an individual air parcel is discussed. It is shown that the general velocity solution of the equation describing this motion may be expressed in terms of the well-known series approximation of Philipps and a rest term; this term describes the inertial motion of the air parcel about a given initial state.
