Unravelling repurposing

The Dutch government and leading academics in the field of circular economy propose that “repurposing”, i.e., finding new usages for discarded material, is important to reduce resource usage. Waste collectors, municipalities and start-ups increasingly find ways to develop circular business models, aiming for minimum loss of material integrity. Repurpose is a circular business model strategy which entails using a discarded product or its parts in a new product with a different function.The aim of this research is to gain a better understanding of this promising but academically underexposed circular strategy by empirically exploring its key characteristics and developing a taxonomy that reflects the scope and potential of the concept. The taxonomy development was based on clustering and comparing 96 case examples using key characteristics and critical factors empirically collected by means of 11 semi-structured expert interviews. The taxonomy was iteratively refined and validated by means of workshops with experts.This paper proposes a taxonomy and a comprehensive definition for repurposing. The Repurpose taxonomy distinguishes three main categories with increasing levels of material integrity: “Reprocess”, “Reshape” and “Recontextualize”. The taxonomy provides a refinement of existing circular business model patterns and frameworks for closing material loops strategies. It shows how repurposing may exploit the creative potential of design to fill the gap between reuse and recycling by retaining previously added value with three levels of physical adjustment.

Oasistan: an intercultural role-playing simulation game to recognize cultural dimensions

Aim. Although cultural dimensions theory is a topical strand of quantitative cultural research, few intercultural simulation games use it. We present the design and review of the application of OASISTAN, an intercultural role-playing simulation game that is specifically based on cultural dimensions theory. Method. OASISTAN was first designed in 1999 for use in Master’s courses on cross-cultural management at Delft University of Technology in the Netherlands, attracting 20-23 year old students with a Bachelor degree in engineering and from various cultural backgrounds. Since its first design the game has been played approximately 45 times at Delft University of Technology in the Netherlands and three times at Harbin Institute of Technology in China in the years 2006-2008. We reviewed their experiences designing and facilitating OASISTAN since 1999. Results. The game has a no-tech role-play design and revolves around the geopolitically complex region of the Caspian Sea, specifically the fictional country of ‘Oasistan’. The game consists of students forming small teams of Oasistani, Western and non-Western public/private actors collaborating with each other to try and reach the common goal of oil exploration and production in this country. In total 15-30 students were involved. We found that OASISTAN allowed its players not only to intensely experience the difficulty and awkwardness of being confronted with cultural differences, but also to interpret and understand these differences through cultural dimensions. Students who played OASISTAN identified ten out of the 12 dimensions by Maleki and De Jong. The two dimensions that students were not able to identify are uncertainty avoidance and collaborativeness. Conclusion. OASISTAN shows how a game design field (i.e., intercultural simulation gaming) can be reinvigorated in light of new or updated scientific theories pertaining to the field’s subject matter (i.e., cultural dimensions). Several opportunities for future research are identified.

Integration or predictability? A further specification of the functional role of gamma oscillations in language comprehension

Gamma-band neuronal synchronization during sentence-level language comprehension has previously been linked with semantic unification. Here, we attempt to further narrow down the functional significance of gamma during language comprehension, by distinguishing between two aspects of semantic unification: successful integration of word meaning into the sentence context, and prediction of upcoming words. We computed eventrelated potentials (ERPs) and frequency band-specific electroencephalographic (EEG) power changes while participants read sentences that contained a critical word (CW) that was (1) both semantically congruent and predictable (high cloze, HC), (2) semantically congruent but unpredictable (low cloze, LC), or (3) semantically incongruent (and therefore also unpredictable; semantic violation, SV). The ERP analysis showed the expected parametric N400 modulation (HC < LC < SV). The time-frequency analysis showed qualitatively different results. In the gamma-frequency range, we observed a power increase in response to the CW in the HC condition, but not in the LC and the SV conditions. Additionally, in the theta frequency range we observed a power increase in the SV condition only. Our data provide evidence that gamma power increases are related to the predictability of an upcoming word based on the preceding sentence context, rather than to the integration of the incoming word's semantics into the preceding context. Further, our theta band data are compatible with the notion that theta band synchronization in sentence comprehension might be related to the detection of an error in the language input.

From therapeutic factors to mechanisms of change in the creative arts therapies

Empirical studies in the creative arts therapies (CATs; i.e., art therapy, dance/movement therapy, drama therapy, music therapy, psychodrama, and poetry/bibliotherapy) have grown rapidly in the last 10 years, documenting their positive impact on a wide range of psychological and physiological outcomes (e.g., stress, trauma, depression, anxiety, and pain). However, it remains unclear how and why the CATs have positive effects, and which therapeutic factors account for these changes. Research that specifically focuses on the therapeutic factors and/or mechanisms of change in CATs is only beginning to emerge. To gain more insight into how and why the CATs influence outcomes, we conducted a scoping review (Nstudies = 67) to pinpoint therapeutic factors specific to each CATs discipline, joint factors of CATs, and more generic common factors across all psychotherapy approaches. This review therefore provides an overview of empirical CATs studies dealing with therapeutic factors and/or mechanisms of change, and a detailed analysis of these therapeutic factors which are grouped into domains. A framework of 19 domains of CATs therapeutic factors is proposed, of which the three domains are composed solely of factors unique to the CATs: “embodiment,” “concretization,” and “symbolism and metaphors.” The terminology used in change process research is clarified, and the implications for future research, clinical practice, and CATs education are discussed.

The phonology of initial cluster coordination: a cross-language articulographic study

Phonotactic and morphonotactic influences on the (a)synchronicity of consonant clusters in Polish

A pilot speech production experiment combined articulatory data obtained using Electromagnetic Articulography (EMA), along with acoustic measures, to investigate the effects of cluster size (CC vs. CCC) and morpheme boundaries on consonant cluster synchronicity for five speakers of Polish. We found that being placed in a larger cluster leads to less synchronous productions of two-consonant sequences. We also found, surprisingly, greater synchronicity for clusters spanning a morpheme boundary than for the same cluster within a morpheme. Our findings may be interpreted from a listener-oriented perspective in which speech production is sensitive to perceptual considerations.
