A case study of intuition and design: Building a tool for parents of premature babies and the nursing staff who care for them

The paper presents a research-based study project conveyed by Media Lab Helsinki in 2007–2008. During the process, the design team constructed a unique audiovisual tool that provides emotional support in coping with the challenges of a premature birth. The purpose of the two-hour DVD, with its three separate parts, is to help family, intensive care staff, and other associated health care personnel to better connect with each other and the tiny babies. As the first audiovisual material, which aims to explain premature babies’ communication and interaction, the end product has proven to be of significant value to Finnish neonatal care and other associated fields. The project was realized in cooperation with the Neonatal Intensive Care Unit in Children’s Hospital, HUCH (Helsinki University Central Hospital), and the design team worked in a network of shared expertise. In the case study the authors used co-design and self-reflection methods to monitor graduate students working with a society-level challenge. The focus was upon the utilisation of intuition in innovations, problem solving, and project management. During the design process, the authors observed the working theory: intuition is the basis of successful decision-making, which leads to innovative solutions. Throughout the design process, the team collected systematically feedback, which was later utilised as a corner stone in the case study. The authors believe that relying on intuition, the design team ended up addressing many hidden issues of the clinic and parenthood of premature babies’. This paper tries to unfold the evolutionary working approach used during the design process, presents highlights of the case study research as well as illuminates the intuitive way of working from designers’ point of view.

Regional Languages on Wikipedia. Venetian Wikipedia’s user interaction over time

Given that little is known about regional language user interaction practices on Wikipedia, this study analyzed content creation process, user social interaction and exchanged content over the course of the existence of Venetian Wikipedia. Content of and user interactions over time on Venetian Wikipedia exhibit practices shared within larger Wikipedia communities and display behaviors that are pertinent to this specific community. Shared practices with\ud other Wikipedias (eg. English Wikipedia) included coordination content as a dominant category of exchanged content, user-role based structure where and most active communicators are administrators was another shared feature, as well as socialization tactics to involve users in online projects. While Venetian Wikipedia stood out for its geographically-linked users who emphasized their regional identity. User exchanges over time spilled over from online to offline domains. This analysis provides a different side of Wikipedia collaboration which is based on creation, maintenance, and negotiation of the content but also shows\ud engagement into interpersonal communication. Thus, this study exemplifies how regional language Wikipedias provide ways to their users not only to preserve their cultural heritage through the language use on regional language Wikipedia space and connect through shared contents of interest, but also, how it could serve as a community maintenance platform that unifies users with shared goals and extends communication to offline realm

Consistency of Maximum Likelihood for Continuous-Space Network Models

Network analysis needs tools to infer distributions over graphs of arbitrary size from a single graph. Assuming the distribution is generated by a continuous latent space model which obeys certain natural symmetry and smoothness properties, we establish three levels of consistency for non-parametric maximum likelihood inference as the number of nodes grows: (i) the estimated locations of all nodes converge in probability on their true locations; (ii) the distribution over locations in the latent space converges on the true distribution; and (iii) the distribution over graphs of arbitrary size converges.Comment: 21 page

Just another BRIC in the wall? The rise of BRICs and educating tomorrow's global managers

The BRIC countries (Brazil, Russia, India, and China) comprise 40 percent of the world’s population (approximately 2.8 billion people), cover more than a quarter of the world’s land area over three continents, and account for more than 25 percent of global GDP (by purchasing power parity). In the ten years since the term BRICs was first coined by Jim O‘Neill, chief economist of the investment bank Goldman Sachs, all economies (except Brazil) have exceeded their predicted growth rates. Integration into the global economy coupled with rising spending power prompts flows of students (and expatriates) to, and from, the BRICs—positioning international business educators at the helm of this sea-change. In this article, we reflect on the implications of the rise of the BRICs for educating the next generation of business managers and leaders. We argue that rather than just another “brick in the wall,” educating tomorrow’s managers requires adoption of a global mindset by international business educators. This enables them to build on, or indeed begin to dismantle, existing theoretical and pedagogical foundations, brick by brick

First-Principles Investigation of Perfect and Diffuse Anti-Phase Boundaries in HCP-Based Ti-Al Alloys

First-principles thermodynamic models based on the cluster expansion formalism, monte-carlo simulations and quantum-mechanical total energy calculations are employed to compute short-range-order parameters and diffuse-antiphase-boundary energies in hcp-based $\alpha$-Ti-Al alloys. Our calculations unambiguously reveal a substantial amount of SRO is present in $\alpha$-Ti-6 Al and that, at typical processing temperatures concentrations, the DAPB energies associated with a single dislocation slip can reach 25 mJ/m$^{2}$. We find very little anisotropy between the energies of DAPBs lying in the basal and prism planes. Perfect antiphase boundaries in DO$_{19}$ ordered Ti$_3$Al are also investigated and their interfacial energies, interfacial stresses and local displacements are calculated from first principles through direct supercell calculations. Our results are discussed in light of mechanical property measurements and deformation microstructure strudies in $\alpha$ Ti-Al alloys
