“…Certain studies have shown that fatty acids are good markers and may be useful for making taxonomic inferences involving different organisms,such as fungi [25], bacteria [26], algae [24], and higher plant families,s uch as Sapindaceae [21] [23], Asteraceae [27], Boraginaceae [28], Vochysiaceae [29], Rubiaceae [30],a nd Malvaceae [31]. Seed-oil fatty acids have been studied more oftenfor this purpose,particularly in higher plants.T he work herein aimedt oi nvestigate the fatty-acid composition of seeds obtained from16Sapindaceae species,todeterminewhether the fatty-acid composition might be usefulfor discerning the tribal and interspecific affinities,and to examineits potential chemotaxonomic significance.I na ddition, the composition of the seed-oil fatty acids of twelve Sapindaceae speciesw ere described for the first time here.T he results are an important indicator of the fatty-acid distribution of the seed oils in this family and its chemosystematic value for Sapindaceae,i np articular for the species of the Paullinieae tribe.…”

Circumscriptions for the Sapindaceae family and its infrafamilial relationships have been widely discussed. Certain groups are highly morphologically similar; thus, it is difficult to identify certain taxa. DNA Analyses have also indicated complex phylogenetic relationships, and it is difficult to relate such analyses to morphological data. Given the above concerns, this study aimed to investigate the fatty-acid profiles of the seed oils of 16 Sapindaceae species belonging to five tribes and to evaluate their potential chemotaxonomic significance. In total, eleven fatty acids were identified, and eicosenoic acid predominated in nine species. Multivariate analyses (principal component and cluster analyses) of the fatty-acid profiles of the seed oils allowed to separate them in two major clusters. The first cluster, characterized by oils with high eicosenoic acid levels, included all species belonging to the Paullinieae tribe (Cardiospermum, Paullinia, and Serjania species). In the second main cluster, the chemical similarity of the oils was lower, and the species belonged to different tribes. Nevertheless, the tree investigated Allophylus species (Thouinieae tribe) constituted a separate subcluster. Thus, the results showed that the fatty-acid composition of the seed oils of Sapindaceae species provide chemotaxonomic support for the separation of the Paullinieae tribe from the other tribes studied.

Serjania genus is native of Neotropics, from Mexico to Northern Argentina, and includes more than 230 species, most of them found in Mexico and Brazil. Although the genus is scarcely studied, the scientific literature and ethnobotanic information suggest that the extracts or fractions of these extracts have components with different biological properties. A bibliographic search in SciFinder and Scopus data carried out in April 2014 and using the keyword Serjania showed eighteen compounds belonging to different classes of natural products identified in seven species of the genus, namely: Serjania communis, S. triqueta, S. salzmanniana, S. grammatophora, S. cuspidata, S. yucatensis and S. caracasana. In this review we discuss the main biological activities of these eighteen natural compounds. The extracts or fractions of extracts of these seven plants described in the literature showed the following biological activities: analgesic, anti-inflammatory, antioxidant, antiprotozoal, anticancer, antibacterial, larvicidal, gastroprotective and insect repelent. Especially relevant is the anticancer activity of some fractions and plant extracts according to the criterion of The American National Cancer Institute for fractions and plant extracts. Of the fatty acids group found in the seeds of the Serjania species described in the literature, most are unsaturated, such oleic, arachidic, and eicosenoic. The latter represents 57% -70% of the total fatty acids content in the Serjania species studied.Keywords: Sapindaceae; Serjania; phytochemistry; biological activities; anticancer. ResumoSerjania é um gênero nativo do Neotrópico, presente desde o México até o norte da Argentina, com mais de 230 espécies, a maioria delas encontradas no México e no Brasil. Embora o gênero seja pouco estudado, os estudos científicos e as informações etnobotânicas descritas na literatura sugerem que extratos ou frações destas espécies podem ter componentes com diversas propriedades biológicas. O levantamento bibliográfico nas bases de dados Scopus e SciFinder realizado em abril de 2014, usando a palavra-chave Serjania, mostrou o registro de 18 compostos de diferentes classes de produtos naturais, distribuídos por sete espécies do gênero, a saber: Serjania communis, S. triqueta, S. salzmanniana, S. grammatophora, S. cuspidata, S. yucatensis e S. caracasana. Nesta revisão são discutidas as principais atividades biológicas destes 18 compostos naturais. Os extratos ou as frações dos extratos destas sete plantas descritas na literatura mostraram as seguintes atividades biológicas: analgésica, anti-inflamatória, antioxidante, antiprotozoária, anticâncer, antibacteriana, larvicida, gastroprotetora e repelente. Dentre as atividades biológicas, a mais importante, pelos critérios adotados pelo The American National Cancer Institute para frações e extratos vegetais, é a anticâncer. Os ácidos oleico, araquídico e eicosenoico foram os principais ácidos graxos encontrados nas sementes das espécies de Serjania descritas na literatura. O ácido graxo eic...

“…Especially for the creation of entrepreneurial Spin-Offs, it is relatively common that the Spin-Off decision is induced and supported by a customer, who is in need of a supplier that is tailored to his needs 200 . If the Spin-Off entrepreneur then takes the opportunity and creates a new company, customers can be attracted to the new company and switch from the former parent to the Spin-Off.…”

The short title of this book has a long history. Writing a PhD is a project in its own right that needs not only scientific objectives and commitment, but also managerial skills. Its completion shows something that holds true for many undertakings: there are many sources of success.Doing successful business is not an easy task. Global competition and free information and financial flows within intertwined systems of governance create a high speed of change and a many uncertainties. Such environment fosters organisational change and makes successful behaviour even more remarkable.Corporate Spin-Offs provide a highly suitable subject for investigating the sources of success. Although they are frequent and highly successful, there is few and heterogeneous literature. And because Corporate Spin-Offs are companies, their analysis can build upon investigation on corporate success factors in general and the results of the project can be relevant for practice. In addition to the scientific and economic interest in Corporate Spin-Offs, there is also political interest in better understanding and promoting Spin-Off phenomena.Fortunately, these observations were not mine alone. from the University of Seville gave this work much of its shape. In a similar way, the present results would be unimaginable without the great support from Jeremy Howells from the University of Manchester, PREST. Åsa Lindholm Dahlstrand from Chalmers University of Technology as well as Annaleena Parhankangas from Helsinki University of Technology prevented this project from losing track. The personal advice of Khaled Elshuraydeh from the Higher Council of Science and Technology in Jordan provided great motivation for achieving scientific coherence and a clear line of thought. This work would not have been possible without the love and support of my wife Elisa. Unfortunately, there is not enough space to mention the many other persons who have supported me with their advice and motivation.I am very grateful for the individual contributions and personal commitment provided during this undertaking and am sure that they are not only highly appreciated by myself but also by the reader. I hope that the reader, whether businessman, politician or researcher, finds this book helpful and a source of inspiration. ABSTRACTCorporate Spin-Offs are highly successful phenomena that produce important impacts on their economic environment. However, existing investigation only delivers partial explanations as it takes into account a too small number of single factors and uses research approaches focused on narrow aspects.The present work has been undertaken in order to investigate the individual contributions of a wide range of factors on the Corporate Spin-Off decision and its success, the influence of the interrelation of the factors and the existence of typologies.The first chapter presents a revision of existing definitions and establishes a general typology. It highlights five main topics: value creation, Corporate Spin-Off policy, framework conditions, the relati...
