“…Lastly, we note that the ventromedial surface of the crests of Platanista is highly rugose, a characteristic that would also influence the reflective properties of the crests. More complex surfaces provide a relatively larger surface for sound to interact with, and thus function better as sound absorbers and sound diffusers than as sound reflectors [72]. However, if the interface between the air sac system and the soft tissue acts to reflect sound, then the surface of this bone may not be important in determining the reflective properties of this system.…”

Many odontocete groups have developed enlarged facial crests, although these crests differ in topography, composition and function. The most elaborate crests occur in the South Asian river dolphin (Platanista gangetica), in which they rise dorsally as delicate, pneumatized wings anterior of the facial bones. Their position wrapping around the melon suggests their involvement in sound propagation for echolocation. To better understand the origin of crests in this lineage, we examined facial crests among fossil and living Platanistoidea, including a new taxon, Dilophodelphis fordycei, nov. gen. and sp., described herein, from the Early Miocene Astoria Formation of Oregon, USA. We measured the physical extent and thickness of platanistoid crests, categorized their relative position and used computed tomography scans to examine their internal morphology and relative bone density. Integrating these traits in a phylogenetic context, we determined that the onset of crest elaboration or enlargement and the evolution of crest pneumatization among the platanistoids were separate events, with crest enlargement beginning in the Oligocene. However, we find no evidence for pneumatization until possibly the Early Miocene, although certainly by the Middle Miocene. Such an evolutionary context, including data from the fossil record, should inform modelling efforts that seek to understand the diversity of sound generation morphology in Odontoceti.

“…As Acklin (2011, p. 2) stated, many SMEs are still unaware of design as a strategic resource because of different types of barriers and problems. Limited human and financial resources, less formal or nonexistent product development and innovation processes (Fueglistaller, 2004), lack of access to design resources (Cox, 2005) or poor design understanding (Moultrie et al , 2007) make difficult the development and integration of a design management function in SMEs.…”

The aim of this paper is to present design management as a dynamic capability and to analyze its mediating role between organizational learning capability and product innovation performance in Small and Medium Enterprises (SMEs). Design/methodology/approach Structural equation modeling is used to test the research hypotheses based on data from the Italian and Spanish ceramic tile industries. The data are derived from the responses of 182 companies (50% of the target population) to a questionnaire addressed to Product Development Managers and Human Resource Managers. Findings The results suggest that organizational learning capability enhances product innovation through the mediation of design management capability. We find an interesting interplay between organizational learning, design management capability and product innovation that can be very useful to better understand how to improve innovation performance. This finding shows that design management, as a dynamic capability, emerges from learning and allows the firm to adapt to environmental changes. Originality / value Several works have studied dynamic capabilities but without specifying the nature of these capabilities. More recent empirically-based studies conceptualize and refer to specific dynamic capabilities. In this paper, we present design management as a dynamic capability. This study aims also to develop a better understanding of how organizational learning capability impacts on the product innovation performance of SMEs and how this relationship is mediated by design management capability.

“…Among the extensive literature on design management, many previous studies focused, for example, on the characteristics of a product design; in particular, a product design may be defined as a “beautiful and well made” product which combines functionality, expressed by technology, with aesthetic form and/or symbolic value (Bloch, 2011; Ravasi and Rindova, 2008; Luchs and Swan, 2011; D'Ippolito, 2014). Other previous studies examined the types of barriers and problems small and medium-sized enterprises (SMEs) have to overcome to adopt DDI such as lack of design resources (Cox, 2005; Landoni et al , 2016) or human and financial resources (Fuesglistaller, 2004; D'Ippolito, 2014) or design culture (Moultrie et al , 2007). Some studies also analysed how a product design creates value for customers as it meets the rational and emotional needs of customers (among others Bloch, 2011; D'Ippolito 2014).…”

PurposeThis paper aims to investigate the phases of new product development within the design-driven innovation (DDI) process, the role of designers and collaborators in the process and how this process relates to some quality principles.Design/methodology/approachThis study adopted a qualitative approach using Gioia methodology. In particular, four Italian manufacturing companies in the home appliances and furniture industry were selected, and data mainly collected through direct interviews were analysed through content analysis.FindingsThe new product development related to DDI includes the following phases: the company brief, the designer research, the concept of the designer, the design, legal protection, prototyping, production and the market launch. Designers play a strategic role in the above phases of DDI, but other actors also cooperate and some quality principles affect positively on the process. This study proposes a model for a DDI process in the home appliances and furniture sector.Research limitations/implicationsAlthough this exploratory study was conducted on only four companies, it advances the DDI research in relation to new product development.Practical implicationsThis study makes recommendations to entrepreneurs and managers on how to innovate successfully and to effectively manage designers and collaborators to ensure competition.Social implicationsThis analysis highlights that design-based innovation contributes to improving the quality of life of consumers.Originality/valueTo the best of the authors' knowledge, this is the first qualitative study to examine the phases of new product development in DDI process, the actors involved and relationship to quality principles for the Italian home appliances and furniture sector.
