Initial Results

Rank Centrality (RC; Negahban, Oh, & Shah 2017) is a rank-aggregation algorithm that computes a total ranking of elements from noisy pairwise ranking information. I test RC as an alternative to incremental error-driven learning algorithms such as GLA-MaxEnt (Boersma & Hayes 2001; Jäger 2007) for modeling a constraint hierarchy on the basis of two-alternative forced-choice experiment results. For the case study examined here, RC agrees well with GLA-MaxEnt on the ordering of the constraints, but differs somewhat on the distance between constraints; in particular, RC assigns more extreme (low) positions to constraints at the bottom of the hierarchy than GLA-MaxEnt does. Overall, these initial results are promising, and RC merits further investigation as a constraint-ranking method in experimental linguistics.

Initial Results

goal of the present discourse analysis is to report on the initial results of a DFG project on communication in interdisciplinary projects. Based on a case study, the following questions were investigated: 1) at what times or phases of a project communication problems occur, 2) what kinds of problems occur as a result of knowledge asymmetries, and 3) which interactive and discourse roles do participants take on when facing such problems? Three main conclusions can be drawn from the findings; first, that linguistic-communicative problems occurring in interdisciplinary projects are not simply a result of attempts to find a “common language”, but are grounded in issues of contextual, methodological, organisitory, and socio-pragmatic agreements. Second, these communication problems arise during the initial, preparatory phases of a project, earlier than social scientific process models suggest, i. e. as early as the writing and submission of the project proposal, as opposed to when the project work actually begins. Third, that these problems, induced by the inevitable presence of knowledge asymmetries among participants, must be resolved not only through active and consistent meta-communication, but also through meta-meta-communication. Evidence for these findings was gathered by means of interviews with project participants in which they reflected on the phase of jointly writing their project proposal from the perspective of their respective disciplines.

Initial Results

Increased knowledge of the processes which govern the transport of solids in sewers is necessary in order to develop more reliable and applicable sediment transport models for sewer systems. Proper validation of these are essential. For that purpose thorough field measurements are imperative. This paper renders initial results obtained in an ongoing case study of a Danish combined sewer system in Frejlev, a small town southwest of Aalborg, Denmark. Field data are presented concerning estimation of the sediment transport during dry weather. Finally, considerations on how to approach numerical modelling is made based on numerical simulations using MOUSE TRAP (DHI 1993).

Education Initiatives

The adoption of energy efficiency practices and increased penetration of renewable energy sources in the power system are estimated to play a key role in the decarbonization of the energy sector, helping reduce greenhouse gas emissions and ultimately fight climate change. To foster energy transition, energy education initiatives should primarily target the citizens and be designed adopting a User-Centered Design (UCD) approach and HCI methodologies. This paper describes how UCD/HCI can inform the design of citizens’ energy education initiatives by presenting a case study—the development of an information platform targeting Madeiran citizens. The article describes the design process, from ideation to prototype and validation. Methods used in each phase (card sorting, semi-structured interviews, brainstorming sessions, think-aloud protocol and surveys) are described. Results of each phase and how they have informed the following steps are presented, together with a detailed description of the resulting information platform and initial results in terms of acceptance and interaction with the system. Our initial results support the hypothesis that adopting an HCI perspective can nurture the development of energy education initiatives targeting citizens, bringing a user-centered approach to the design of such initiatives.

Initial Results

This article presents a method for costume design, where empathy and embodiment are used as methodological choices by the designer in the character-creation process. In creating references for the sketching process, costume designers combine photos in which they portray themselves as the character that they imagine. These role-selfies, taken with a handheld tablet, work as starting points for the sketching procedure. The material for the present study is collected from MA costume design students who participated in digital character-creation courses at Aalto University, in Helsinki, Finland, and is a part of doctoral research by the author. The data are collected through a mixed-method approach and is organized as a case study investigating the experiences of using the body as a source for costume design. The research question in this study is as follows: does an awareness of one’s own body facilitate the sketching process? The initial results show that the research participants consider the method useful because it enables them to experience a stronger bodily connection with the digital medium, the imagined design and the emerging character in the costume sketching process. Hence, the findings of this study can be used to develop design and teaching practices not only in the field of costume design but also in other design processes involving character creation.

Persistence Conditions

The conditions under which certain complex polysemous nominals can sustain coherent sense relations (informally, can “survive”) is investigated through a two-alternative forced choice experiment. Written scenarios were constructed which permitted copredication, through which multiple, semantically different sense types are associated with a single nominal. Participants were presented with two scenarios involving a polysemous nominal (e.g., bank, city) and had to select which scenario (and, hence, which combination of predicates) appeared to be the most prototypical, faithful realization of the nominal. In order to achieve this, an additional manipulation was added, such that the number of senses hosted by each forced choice was either equal (2 senses choice vs. 2 senses choice) or unequal (1 sense choice vs. 2/3 senses choice). In order to address certain concerns in the literature about prototypicality, a core question addressed was whether the institutional sense of the nominals strongly determined the option chosen by participants, or whether the number of senses more strongly predicted this. It was found that the best predictor of sense “survival” was not sense frequency, but rather sense complexity or approximation to the institutional sense.
