A Hierarchical Framework of New Products Development : an Example from Biotechnology

Alexandre, Maria Tereza ; Furrer, Olivier ; Sudharshan, D.

In: European Journal of Innovation Management, 2003, vol. 6, no. 1, p. 48-63

Many new products are based on new technologies, which may in turn be based on new scientific discoveries. The extant literature on new product development has focused on how a firm may successfully commercialize new products. There is a corporate cost associated with new product failure, which extends beyond the final product-manufacturing corporation to all the parties involved in the...

Fossil amphibians and reptiles from the Neogene locality of Maramena (Greece), the most diverse European herpetofauna at the Miocene/Pliocene transition boundary

Georgalis, Georgios L. ; Villa, Andrea ; Ivanov, Martin ; Vasilyan, Davit ; Delfino, Massimo

In: Palaeontologia Electronica, 2019, p. -

We herein describe the fossil amphibians and reptiles from the Neogene (latest Miocene or earliest Pliocene; MN 13/14) locality of Maramena, in northern Greece. The herpetofauna is shown to be extremely diverse, comprising at least 30 different taxa. Amphibians include at least six urodelan (Cryptobranchidae indet., Salamandrina sp., Lissotriton sp. [Lissotriton vulgaris group], Lissotriton sp.,...

Early Miocene herpetofaunas from the Greek localities of Aliveri and Karydia – bridging a gap in the knowledge of amphibians and reptiles from the early Neogene of southeastern Europe

Georgalis, Georgios L. ; Villa, Andrea ; Ivanov, Martin ; Roussiakis, Socrates ; Skandalos, Panagiotis ; Delfino, Massimo

In: Historical Biology, 2019, vol. 31, no. 8, p. 1045–1064

We here describe new remains of amphibians and reptiles from the early Miocene (MN 4) of two different Greek localities, Aliveri and Karydia. The newly described material consists of urodelans, alytids, indeterminate anurans, turtles, crocodylians, lacertids, indeterminate scincomorphs, anguids, colubrids, viperids, and indeterminate snakes. The presence of the frog Latonia cf. gigantea in...

The last amphisbaenian (Squamata) from continental Eastern Europe

Georgalis, Georgios L. ; Villa, Andrea ; Delfino, Massimo

In: Annales de Paléontologie, 2018, vol. 104, no. 2, p. 155–159

The fossil record of amphisbaenians in Europe has recently been augmented through the description of new finds across the continent. It has been suggested that the post- Miocene range of amphisbaenians followed a progressive southward constriction that ultimately lead to their extant disjunct distribution. We herein describe amphisbaenian vertebral material from the Pliocene of northern...
