Evolving missions and university entrepreneurship:Academic spin-offs and graduate start-ups in the entrepreneurial society

A recent call has urged to broaden the conceptualization of university entrepreneurship in order to appreciate the heterogeneity of contexts and actors involved in the process of entrepreneurial creation. A gap still persists in the understanding of the variety of ventures generated by different academic stakeholders, and the relationships between these entrepreneurial developments and university missions, namely, teaching and research. This paper addresses this particular gap by looking at how university teaching and research activities influence universities’ entrepreneurial ventures such as academic spin-offs and graduate start-ups. Empirically, we analyse the English higher education sector, drawing on institutional data at the university level. First, we explore the ways in which teaching and research activities are configured, and secondly, we examine how such configurations relate to academic spin-offs and graduate start-ups across different universities over time. Our findings suggest, first, that the evolution of USOs and graduate start-ups exhibit two different pathways over time; and second, that teaching and research both affect entrepreneurial ventures but their effect is different.JRC.B.4-Human Capital and Employmen

Efeito do lítio sobre a hiperatividade locomotora induzida pela lesão eletrolítica da região do núcleo mediano da rafe em ratos Effect of lithium treatment on the locomotor hyperactivity induced by the lesion of the region of the median raphe nucleus in rats

A lesão do núcleo mediano da rafe (NMR) produz sintomas que sugerem validade de face ao episódio maníaco. Esta pesquisa avaliou o efeito do lítio sobre a hiperatividade locomotora induzida por esta lesão. Vinte e um ratos Wistar machos foram submetidos à lesão eletrolítica da região do NMR (LR) e 17 foram submetidos à lesão fictícia (LF). Após recuperação, a atividade locomotora foi avaliada na caixa de atividade (Med Associates/ENV-515). Parte dos animais destes grupos recebeu tratamentos com lítio (47,5 mg/kg/2x dia i.p.) por 10 dias, enquanto o restante foi tratado com salina no mesmo esquema. A reavaliação ao final dos tratamentos demonstrou que o lítio reduziu significantemente a atividade locomotora em relação à avaliação inicial no grupo LR (ANOVA/Bonferroni p < 0,05), tornando-a equivalente aos baixos níveis dos grupos LF. Estes dados sustentam a hipótese de que as manifestações induzidas pela lesão do NMR podem constituir um modelo animal de mania.<br>The lesion of the Median Raphe Nucleus (MRN) produces symptoms that suggest face validity for manic episodes. This research evaluated the effect of lithium treatment on the locomotor hyperactivity induced by this lesion. Twenty-one Wistar male rats were submitted to the lesion of the region of the MRN (LR) and 17 were sham lesioned (LF). After recovery, the locomotor activity was evaluated in an activity chamber (Med Associates/ENV-515). A subgroup received lithium (47.5 mg/kg/twice a day i.p.) for 10 days, while the other animals received saline in the same schedule. The reevaluation at the end of the treatments showed that only lithium significantly reduced the activity of LR group compared to baseline levels (ANOVA/Bonferroni p < 0.05), making it equivalent to low levels of LF groups. These data support the hypothesis that the behavioral manifestations induced by the lesion of the MRN may constitute an animal model of mania
