Randomized controlled trial comparing embryo culture in two incubator systems: G185 K-System versus EmbryoScope
2017
Objective To study whether the closed culture system, as compared with a benchtop incubator with similar culture conditions, has a positive impact on intracytoplasmic sperm injection (ICSI) outcomes. Design Randomized controlled trial. Setting University hospital. Patient(s) A total of 386 patients undergoing ICSI cycles with at least six mature oocytes were randomized. Intervention(s) Of these patients, 195 were assigned to the group with culture in a time-lapse imaging (TLI) system (EmbryoScope) and 191 to the group with culture in the G185 K-System (G185). Main Outcome Measure(s) Rate of implantation (primary endpoint) and embryo morphology grade. Result(s) No significant differences wer…
University incubator as catalyst of resources for academic spin-offs. The case of ARCA Consortium
2013
Today we can observe an increasing proliferation of new academic spin-off initiatives aimed to transfer knowledge from the university to the market. Due to their strategic role in enhancing the development of technological innovation, academic spin-offs can attain high levels of social performance and consonance with their environment. At the same time, they must overcome many difficulties if they are to achieve a high level of financial performance and growth. They are often considered to be mere vehicles for the transmission of knowledge, implying that their entrepreneurial potential is not fully exploited. According to the Resource Based View (RBV) the competitive disadvantage of an acad…
Clinical validation of embryo culture and selection by morphokinetic analysis: a randomized, controlled trial of the EmbryoScope.
2014
Objective To determine whether incubation in the integrated EmbryoScope time-lapse monitoring system (TMS) and selection supported by the use of a multivariable morphokinetic model improve reproductive outcomes in comparison with incubation in a standard incubator (SI) embryo culture and selection based exclusively on morphology. Design Prospective, randomized, double-blinded, controlled study. Setting University-affiliated private in vitro fertilization (IVF) clinic. Patient(s) Eight hundred forty-three infertile couples undergoing intracytoplasmic sperm injection (ICSI). Intervention(s) No patient intervention; embryos cultured in SI with development evaluated only by morphology (control …
Embryo incubation and selection in a time-lapse monitoring system improves pregnancy outcome compared with a standard incubator: a retrospective coho…
2012
Objective To quantify the effect on reproductive outcome of culturing and selecting embryos using a novel time-lapse monitoring system (TMS). Design Retrospective observational cohort study. Setting University-affiliated private center. Patient(s) Donation and autologous intracytoplasmic sperm injection (ICSI) cycles from ten IVF clinics using similar procedures, cultured in TMS (n = 1,390) or in a standard incubator (SI; n=5,915). Intervention(s) None. Main Outcome Measure(s) Clinical pregnancy rate confirmed by ultrasound in week 7. Result(s) A logistic regression analysis, which included all significant confounding factors, was used to evaluate the effect of culturing and selecting embry…
Impacts of ambient temperature and clutch size on incubation behaviour onset in a female-only incubator songbird
2021
Ambient temperature is assumed to be the major cue used by passerines to synchronize their laying and hatching dates to the expected peak of prey availability. While laying eggs, females are still able to fine-tune their hatching date following increasing or decreasing patterns of ambient temperature, mostly via changes in incubation onse t. The onset of incubation behaviour in relation to the laying sequence could have later conse- quences for the duration of the incubation period and the extent of hatching asynchrony. Clutch size is also known to affect incubation patterns and might therefore condition potential responses to changing temperatures. In this study we assessed the association…
New evidence on accelerator performance based on funding and location
2020
Seed accelerators (SAs) appear as a more advanced version of business incubators. These for-profit organizations in exchange of equity, help setting new start-ups by providing mentoring and funding during its first months. Due to their emergent nature, the impact and expectations of SAs remains largely unknown. Therefore, the purpose of this study is to throw new light on this field by empirically assessing for the first time the performance and prospects of these organizations through a survey of 116 SAs.,A model based on the Business Incubators literature is built with four categories covering size, location, age and profitability variables, leading to two hypotheses to be tested empirica…
Innovazione e Imprenditorialità. Il ruolo degli spin-off universitari.
2013
Oggi il ruolo delle Università non si limita più soltanto alle tradizionali attività di formazione e di ricerca. La cosiddetta Seconda Rivoluzione Accademica ha attribuito alle Università una "terza missione", che consiste nella valorizzazione e commercializzazione della conoscenza accedemica sul mercato. L'Università diviene così "entrepreneurial university" creando valore non solo in termini di conoscenza ma anche di innovazione e sviluppo economico. Il libro intende approfondire il ruolo che le Università rivestono nel processo di trasferimento di conoscenza innovativa al mercato tramite la costituzione di imprese spin-off. Viene evidenziato come, attraverso il supporto di apposite strut…
Knowledge flow in Technological Business Incubators: Evidence from Australia and Israel
2015
The study of the contribution of incubators to economic growth started to gain momentum in the 1980s, following the growth of the incubation phenomenon. While acknowledging the challenge of evaluating incubators׳ outcomes, we shift the focus from incubators׳ performance to their internal processes, in particular, the interrelationships through which the incubator stakeholders share knowledge. The literature suggests that small new ventures tend to fail because they lack managerial experience and ability to raise capital in an early stage. Incubators are expected to overcome these obstacles by offering experienced monitoring skills and by enhancing access to capital at a firm׳s early stage. …
A relational view of start-up firms inside an incubator. The case of the ARCA Consortium
2018
Purpose Analyzing the entrepreneurial ecosystem related to the ARCA consortium, the purpose of this paper is to study the relationships among the start-up firms inside an incubator. Design/methodology/approach Thanks to the adoption of the relationships concentric model and the density concentric model, the paper highlights the role of relational conditions for innovative projects in partnership among the incubated firms. Reflections herein are tested via a qualitative research approach based on a single case study: the ARCA consortium. Findings This research found that about 32 percent of relationships inside the incubator support the emergence of short-term relationships among the incuba…
Firm survival: The role of incubators and business characteristics
2015
This paper analyzes the impact of business incubators on firm survival. Using a configurational comparative method, namely fuzzy-set qualitative comparative analysis (fsQCA), the article also examines whether degree of business innovation, size, sector, and export activity affects firm survival. Results show that, when combined with other variables (i.e. sector, technology), business size is a sufficient condition for firm survival. Likewise, incubators alone cannot affect survival. A combination between incubators and other factors is necessary to ensure firm survival. Sin financiación 2.129 JCR (2015) Q2, 40/120 Business UEV
