Towards Understanding Startup Product Development as Effectual Entrepreneurial Behaviors
2017
With the rapid development of technology and competitiveness of IT sectors, the speed of learning and evolving is vital for success of software startups. However, software startups often face with multiple technical and business challenges, which lengthen the duration of their idea-to-launch process. Little is known about the relation of entrepreneurial characteristics of software startups and their product development. We conducted an empirical study on twenty software startups to understand their challenges that leads long idea-to-launch processes. Six engineering-related challenges were identified and interpreted via a lens of an entrepreneurial behavior theory. Our main finding is that …
Eco-sustainable energy and environmental strategies in design for recycling: the software “ENDLESS”
2003
Abstract This paper describes a model, named “ENDLESS”, useful to address the design process towards more eco-compatible solutions. In particular, this tool can support the designer in the choice of the product with an higher recyclability potential from a set of different alternatives. The model takes into consideration a Multi-Attribute Decision-Making method and allows calculating a “Global Recycling Index” (GRI) starting from a set of energy, environmental, technical and economic indicators. A weight is assigned to each parameter following the experience of the designer; a sensitivity analysis is then performed to state how the different assumptions can affect the final results. The mod…
Electron paramagnetic resonance line shape investigation of the Si-29 hyperfine doublet of the E'γ center in a-SiO2
2007
We report an experimental study by electron paramagnetic resonance (EPR) spectroscopy of the E′γ center and of its hyperfine structure, consisting in a pair of lines split by 42 mT. Our results show that two types of E′γ centers can be distinguished on the basis of the EPR line shapes of their main resonance line and hyperfine structure. (© 2007 WILEY-VCH Verlag GmbH & Co.

Example, please! Comparing the effects of single customer reviews and aggregate review scores on online shoppers' product evaluations
2014
Many websites of online retail stores display two forms of electronic word of mouth on a single product site, namely single customer reviews and aggregate review scores. This study compares the effects of simultaneously presented single customer reviews and aggregate review scores on product evaluations of visitors of online retail stores. We hypothesize that well-argued single customer reviews should be more influential than aggregate review scores that display the mean rating of all published reviews of a product. Drawing on a 2 × 2 factorial online experiment, we show that a single customer review is effective, even when potential buyers do not perceive it as representing overall custome…
The Implementation of Dual VET in Spain: An Empirical Analysis
2019
This paper provides a brief overview of how Dual VET was implemented in the Spanish VET system. Dual VET was first regulated in Spain by the end of 2012 with the aim to replace the existing work experience module (FCT) within formal VET. However, companies have hardly contributed to its development, and the educational administrations that mandated it did not support its anchorage in the economy, while forcing VET schools and teachers to introduce it. This has resulted in an example of how not to implement educational reforms. We will use our own empirical research as well as secondary analysis of empirical studies to analyze the views of VET teachers on the whole process and the added valu…
Standards Initiatives for Software Product Line Engineering and Management within the International Organization for Standardization
2010
Software product line engineering is an established methodology for fast and effective development of software-intensive systems and services. To reap maximum benefits from the methodology, businesses typically need to implement coordinated changes in development methodologies, tools, product architectures, organizational designs, and business models. Product lines are developed in complex international software ecosystems, but there is no coordinated set of international standards for defining and leveraging the methodology. As a result, ecosystems cannot adopt standardized methods and tools for developing product lines, tool vendors face difficulties in developing tools to enable product …
Teaching methodology for Design for Six Sigma and Quality techniques – an approach that combines theory and practice
2017
Abstract Quality techniques and Design for Six Sigma methodology are complex areas that need to be understood through correlation of theoretical and practical teaching. Universities started to apply different approaches for achieving better results, on building greater knowledge and skills for their students. The paper presents a methodology of teaching quality techniques and DFSS methodology, an approach that is focused on understanding the concepts through technical examples from industry and applying the knowledge within a project. A model is proposed for teaching Design for Six Sigma methodology through a workshop done in the classroom. The students are split into groups and will practi…

Innovation in Traditional Food Products
2016
International audience; Innovation is widely accepted as one of the keys to being successful. However, companies can innovate and still fail if markets fail to accept the innovation. In most cases, the acceptance of an innovation depends on the innovation itself and also on the product to which it is applied. In this chapter acceptance of different innovations in traditional food products is investigated, thus focusing on the definition of the "traditional" and "innovation" concepts from the consumer's perspective. Qualitative and quantitative approaches are combined to better understand and predict the possibilities of success when applying different generic and specific innovations in tra…
S-domain modeling of conducting post in rectangular waveguides by the BI-RME method
2002
This paper describes the application of the Boundary Integral - Resonant Mode Expansion method to the modeling of a conducting post in a rectangular waveguide. The mathematical model of this structure is determined in a very short time, in the form of pole expansion of the Generalized Admittance Matrix in the s-domain. This model is very useful in the CAD of combline or interdigital filters.
