Designing requirements engineering research

Engineering sciences study different different topics than natural sciences, and utility is an essential factor in choosing engineering research problems. But despite these differences, research methods for the engineering sciences are no different than research methods for any other kind of science. At most there is a difference in emphasis. In the case of requirements engineering research - and more generally software engineering research - there is a confusion about the relative roles of research and about design and the methods appropriate for each of these activities. This paper analyzes these roles and provides a classification of research methods that can be used in any science—engineering or otherwise

Artists Don\u27t Get No Respect: Panel on Attribution and Integrity

When I was considering the question of the moral right to attribution and how unauthorized fan creativity relates to that concept, it struck me that there are two interesting issues from a theoretical perspective. The first is: who gets the credit? When I was in law school and discovered fan fiction, the reason why I got into intellectual property was because most of these stories had a disclaimer-no copyright infringement intended, these characters aren\u27t mine, I\u27m not making any money, please don\u27t sue. And as a student, my question was – does that work? Is that good enough? I was interested in these disclaimers because copyright law does not have an explicit place in the fair use test for evaluating disclaimers as a factor favoring a defense in the way that trademark law does. I, nonetheless, concluded that, in general, fan fiction was going to be fair use. It has yet to be litigated to any particular conclusion. Although cease and desist letters do so still go out, and fans still either comply or they say no, generally there is no result. That is, I think a lot of the copyright owners are unwilling to deal with the publicity and the possibility of finding this as fair use in a litigated case

Perception of Employers' in Transforming Technical and Vocational Education and Training vis-a-vis Emerging Technology Tools for Sustainable Workforce Development in Nigeria

Economic competitiveness of a country depends to a large extent on the skills of its workforce. The skills and the competencies of the workforce, in turn, are dependent upon the quality of the country’s education and training. Education and training are undergoing continuous change, and this change poses more challenges to the 21st-century workforce, and to training institutions. Despite the importance of TVET in transforming economic development, of any nation, Nigeria still has different perspectives about the competency of its TVET graduates. Therefore, the paper aims at determining the perceptions of Organized Private Sector (OPS) employers’ regarding the competency of TVET graduates and the role of emerging technology tools in transforming TVET for a sustainable workforce development. Using a descriptive survey research design and a sample of 80 OPS employers. A validated and piloted questionnaire based on a 5-point Likert scale used as the data collection instrument for the study. Data were analysed using descriptive and inferential statistics including means, standard deviation and ANOVA. Data analysis was facilitated using the Statistical Package for Social Sciences (SPSS). Findings revealed that employers were not satisfied with the competency level of TVET graduates as it is showed that they are not well prepared to enter the competitive workforce and to be self-reliant. Given the nature and complexity of the field of TVET for a sustainable workforce, it was recommended that the utilization of adequate planning and management of emerging technology tools and resources in teaching TVET programs could contribute enormously to the quality and sustainability of the Nigerian workforce

Historical and Projected Surface Temperature over India during the 20th and 21st century.

Surface Temperature (ST) over India has increased by ~0.055 K/decade during 1860-2005 and follows the global warming trend. Here, the natural and external forcings (e.g., natural and anthropogenic) responsible for ST variability are studied from Coupled Model Inter-comparison phase 5 (CMIP5) models during the 20th century and projections during the 21st century along with seasonal variability. Greenhouse Gases (GHG) and Land Use (LU) are the major factors that gave rise to warming during the 20th century. Anthropogenic Aerosols (AA) have slowed down the warming rate. The CMIP5 projection over India shows a sharp increase in ST under Representative Concentration Pathways (RCP) 8.5 where it reaches a maximum of 5 K by the end of the 21st century. Under RCP2.6 emission scenarios, ST increases up to the year 2050 and decreases afterwards. The seasonal variability of ST during the 21st century shows significant increase during summer. Analysis of rare heat and cold events for 2080-2099 relative to a base period of 1986-2006 under RCP8.5 scenarios reveals that both are likely to increase substantially. However, by controlling the regional AA and LU change in India, a reduction in further warming over India region might be achieved

Power, agency, deference and difference Examining the politics of composer–performer relationships in the wake of recent innovations

With a view to uncovering the political implications of notational, technological and musical innovation in composer–performer relationships within Western art music, this paper examines three disparate works: Christian Wolff’s Duo for Pianists II (1958); Brian Ferneyhough’s Unity Capsule (1975); and Georg Hajdu’s Schwer… unheimlich Schwer (2009). By first exploring two innovative 20th century works, Duo for Pianists II and Unity Capsule, the paper establishes a framework for a discussion of the political and ethical dimensions of composer–performer relationships in relation to the 21st century innovation manifest in Schwer… unheimlich Schwer (2009). This multidimensional examination draws on Warren’s (2014) examination of the relationships between ethics and music, Godlovitch’s (1998) philosophy of performance, and research carried out by practitioners such as Couroux (2002), Schick (2006) and Eigenfeldt (2011; 2014). The paper concludes that all three pieces demonstrate the potential for notation to have strong political implications, and that composers are ultimately responsible for the political implications of the performance experience

Mapping the unseen: making sense of the subjective image.

It used to be thought that photography, as a kind of automatic mapping, could provide an objective view of the world. Now we are aware of the power of framing and other interventions between what is 'out there' and what is captured in depiction. Perhaps even perception, let alone depiction, shares this subjectivity? The Sapir-Whorf hypothesis holds that different cultures actually see the world in different ways, as evidenced and influenced by concepts in their languages – though this idea has been derided, for example by Pinker. A key difficulty is that the word subjectivity is bandied about without care for its different meanings and without distinguishing the many forms it takes in the graphic image. If into this muddle we introduce the idea of interactivity, still greater confusion easily follows. The chapter brings some order to different kinds and levels of subjectivity by documenting how they are reflected in forms of graphical mapping. In the process, it becomes clear how significant is the change in media technologies from those bound by the conventional rectangles of the page and screen to media which are interactive, pervasive, multimodal, physical and social
