Subgroups and strictly closed invariant C*-subalgebras [article]

Pekka Salmi
2011 arXiv   pre-print
We characterise the strictly closed left invariant C*-subalgebras of the C*-algebra C_b(G) of bounded continuous functions on a locally compact group G. On the dual side, we characterise the strictly closed invariant C*-subalgebras of the multiplier algebra of the reduced group C*-algebra C*_r(G) when G is amenable. In both cases, these C*-subalgebras correspond to closed subgroups of G.

Idempotent states on locally compact groups and quantum groups [article]

Pekka Salmi
2012 arXiv   pre-print
This is a short survey on idempotent states on locally compact groups and locally compact quantum groups. The central topic is the relationship between idempotent states, subgroups and invariant C*-subalgebras. We concentrate on recent results on locally compact quantum groups, but begin with the classical notion of idempotent probability measure. We also consider the 'intermediate' case of idempotent states in the Fourier--Stieltjes algebra: this is the dual case of idempotent probability

Since the 1980s Finnish commercial salmon fisheries have been strictly regulated, primarily by closed seasons (Salmi and Salmi 2005) .  ...  The geographical distances, different motivations for fishing, regional cultures and divergent knowledge bases are elements that have made the governance of salmon fishery challenging (Salmi and Salmi  ...

Idempotent states on locally compact quantum groups [article]

Pekka Salmi, Adam Skalski
2011 arXiv   pre-print
Idempotent states on a unimodular coamenable locally compact quantum group A are shown to be in one-to-one correspondence with right invariant expected C*-subalgebras of A. Haar idempotents, that is, idempotent states arising as Haar states on compact quantum subgroups of A, are characterised and shown to be invariant under the natural action of the modular element. This leads to the one-to-one correspondence between Haar idempotents on A and right invariant symmetric expected C*-subalgebras of

Contractive idempotents on locally compact quantum groups [article]

Matthias Neufang, Pekka Salmi, Adam Skalski, Nico Spronk
2013 arXiv   pre-print
A general form of contractive idempotent functionals on coamenable locally compact quantum groups is obtained, generalising the result of Greenleaf on contractive measures on locally compact groups. The image of a convolution operator associated to a contractive idempotent is shown to be a ternary ring of operators. As a consequence a one-to-one correspondence between contractive idempotents and a certain class of ternary rings of operators is established.

The Impact of Public R&D Funding on Open Innovation

Pekka SALMI
2012 Economia: Seria Management  
While the effects of public R&D funding on innovation inputs, outputs and strategies of firms have been studied extensively, little is known about the impact public R&D funding may have on open innovation practices. We made several hypotheses about different effects of public subsidies from the open innovation point of view and then tested these hypotheses with data that comes from a survey on innovation practices in China, Finland and Spain. More specifically, the prevalence of open innovation
more » ... in a country was hypothesized to be related to the level of public R&D funding. The results show that Chinese firms make external technology/IP acquisitions more often, as well as engage more frequently in selling of intellectual assets, than their Spanish (and Finnish) counterparts. The results also show that Chinese firms are less likely to make new collaboration agreements after participating in publicly funded R&D projects. The findings therefore generally support the idea that a lower level of available public R&D funding facilitates the adoption of open innovation practices in firms.

Barriers to Open Innovation: Case China

Irina Savitskaya, Pekka Salmi, Marko Torkkeli
2010 Journal of Technology Management & Innovation  
The notion of open innovation suggests that firms can boost their innovative performance by both acquiring knowledge from outside the company and deploying external paths to market for commercialization of non-core technologies. As innovations emerge increasingly from interorganisational cooperation, the background for such cooperation can also have an impact on the involvement of companies into open innovation processes. Thereby this paper proposes to analyze the barriers towards open

Our findings indicate that economic systems and institutions (in particular the protection of IPRs) may have large effects on the behaviour of firms with respect to their engagement in open innovation practices. On the other hand, our results also suggest that the importance of appropriability regime may differ in the buy and sell sides of knowledge, and finally we demonstrate the influence of peculiarities of national cultures upon the adoption of certain elements of open innovation model.

Dermatitis Herpetiformis: A Common Extraintestinal Manifestation of Coeliac Disease

Timo Reunala, Teea Salmi, Kaisa Hervonen, Katri Kaukinen, Pekka Collin
2018 Nutrients  
Dermatitis herpetiformis (DH) is a common extraintestinal manifestation of coeliac disease presenting with itchy papules and vesicles on the elbows, knees, and buttocks. Overt gastrointestinal symptoms are rare. Diagnosis of DH is easily confirmed by immunofluorescence biopsy showing pathognomonic granular immunoglobulin A (IgA) deposits in the papillary dermis. A valid hypothesis for the immunopathogenesis of DH is that it starts from latent or manifest coeliac disease in the gut and evolves

The mean age at DH diagnosis has increased significantly in recent decades and presently is 40-50 years. The DH to coeliac disease prevalence ratio is 1:8 in Finland and the United Kingdom (U.K.). The annual DH incidence rate, currently 2.7 per 100,000 in Finland and 0.8 per 100,000 in the U.K., is decreasing, whereas the reverse is true for coeliac disease. The long-term prognosis of DH patients on a gluten-free diet is excellent, with the mortality rate being even lower than for the general population.

Quasi-actions and rough Cayley graphs for locally compact groups [article]

Pekka Salmi
2013 arXiv   pre-print
We define the notion of rough Cayley graph for compactly generated locally compact groups in terms of quasi-actions. We construct such a graph for any compactly generated locally compact group using quasi-lattices and show uniqueness up to quasi-isometry. A class of examples is given by the Cayley graphs of cocompact lattices in compactly generated groups. As an application, we show that a compactly generated group has polynomial growth if and only if its rough Cayley graph has polynomial
