2015 Administrative Science Quarterly  
to lose their entire investment in most cases-and they rely on a combination of expertise-based intuition and formal analysis in which intuition trumps analysis, contrary to reports in other investment  ...  Using an inductive theory-development study, a field experiment, and a longitudinal field test, we examine early-stage entrepreneurial investment decision making under conditions of extreme uncertainty  ...  This served to both affirm (in the case of positive intuitions about the entrepreneur) and deny (in the case of their analysis of the business viability data) content to create a consistent set of cognitions  ...

Reducing Conservatism in Model-Invariant Safety-Preserving Control of Propofol Anesthesia Using Falsification [article]

Mahdi Yousefi, Klaske van Heusden, Ian M. Mitchell, J. Mark Ansermino, Guy A. Dumont
2018 arXiv   pre-print
Model-invariant formal verification is used to formalize the safety system. This technique requires a multi-model description of model-uncertainty.  ...  This work provides a formalized model-invariant safety system for closed-loop anesthesia that uses feedback from measured data for model falsification to reduce conservatism.  ...  [27] described the effect of alfentanil on BP using a linear model.  ...

Are Formal Planners More Likely To Achieve New Venture Viability? A Counterfactual Model And Analysis

Francis J. Greene, Christian Hopp
2017 Strategic Entrepreneurship Journal  
This study develops and tests a counterfactual model of the relationship between formal written business plans and the achievement of new venture viability.  ...  To test our model, we use propensity score matching to identify the impact that founder, venture and environmental factors have on the decision to write a formal plan (selection effects).  ...  These are vital because estimates of, in our case, plan effects on venture viability, are sensitive to the use of predictor variables and matching estimators.  ...

From Resistance to Transformation: A Generic Metric of Resilience Through Viability

Christophe Béné, Luc Doyen
2018 Earth's Future  
Those categories are then reframed into a generic metric, using viability analysis-a mathematical formalism which builds on dynamic systems and control theory.  ...  To illustrate this new metric, we draw on two models widely discussed in the resilience literature: the exploitation of renewable resources and the case of lake eutrophication.  ...  Acknowledgments The initial part of this work has been carried out with support from the Institut Henri Poincaré (IHP) in Paris during the trimester "mathematics of bio-economics" organized as part of  ...

Evaluating Factors Affecting Performance of Land Reform Beneficiaries in South Africa

Colleta Gandidzanwa, Aart Jan Verschoor, Thabo Sacolo
2021 Sustainability  
Using a sample of 1956 redistributed farms across the nine provinces of South Africa, the current study employs an ordinary least square regression as well as a generalised logistic regression model to  ...  The study provides valuable insight to programme managers on the factors that needs to be enhanced in order to increase the odds of success for redistributed farms.  ...  Whilst the Agricultural Research Council team developed the methodology using a panel of experts from the different ARC institutes, Entsika's logistical support in panel discussions is acknowledged.  ...

In Pursuit of Time: Business Plan Sequencing, Duration and Intraentrainment Effects on New Venture Viability

Christian Hopp, Francis J. Greene
2017 Journal of Management Studies  
In this study, we examine three under-explored dimensions of the temporal relationship between formal written business plans and the achievement of new venture viability.  ...  First, we theorize and investigate the effects of plan sequencing; arguing that a business plan written early on in new venture development increases the prospects of venture viability.  ...  Our pursuit in this study is to theorize and empirically assess how formal plan timing effects impact on the achievement of new venture viability.  ...

Stockless organic farming: strengths and weaknesses evidenced by a multicriteria sustainability assessment model

Bruno Colomb, Matthieu Carof, Anne Aveline, Jacques-Eric Bergez
2012 Agronomy for Sustainable Development  
Tested case studies were based on 44 real cropping systems identified on 19 farms in the Midi-Pyrenees region of France and on 23 cropping system types developed by the advisers from the Centre, Ile-de-France  ...  The effective use of those models is still a challenge, notably for low-input systems.  ...  We are very grateful to the editorial team and the anonymous reviewers for their helpful comments on improving the paper.  ...
