| Abstract: | Given that many voices have argued in favour of combining insights on urban metabolism from different disciplinary angles, there seems to be no lack of general willingness to engage in interdisciplinary research on urban metabolism. Instead, we argue, the central problem lies in the nitty-gritty and mundane practicalities of working across research teams, departments and temporalities. In this paper, we offer a detailed description of an interdisciplinary collaboration that has occurred in practice: a joint effort on the study of potential transition scenarios regarding the metabolism of biowaste in the city-region of Brussels. This inter-project collaboration involved four different research teams from three faculties and two universities, each with a specific set of expertise and interests. Biowaste metabolism and nutrient recirculation is a recurring theme in the literature on urban metabolism. It relates to early studies on urban metabolism and concerns about the depletion of soil fertility and different forms of pollution. The paper describes each research project point of departure in order to allow readers with different disciplinary backgrounds to apprehend the distance that separated the projects before they decided to work together on the urban biowaste metabolism. Furthermore, we present moments of convergences that helped to bring these research processes together. Finally, we offer a critical reflection, suggesting both enabling factors and limits of the inter-project collaboration on biowaste metabolism in Brussels. |

| Abstract: | Scientific papers submitted for publication from U.S. Small Business Innovation Research (SBIR)-funded research projects are an innovative output that has yet to be studied systematically. Using a knowledge production framework, we identify empirically covariates with the number of scientific papers resulting from SBIR projects over the period 1992 through 2001. We find empirically that when the firm involves a university in its funded project, more scientific papers result. When the form of university involvement is taken into account, we find the greatest impact on the output of scientific papers comes from the inclusion of an individual from the university who originally developed the technology being pursued by the firm in its SBIR project. In other words, the project-specific technical human capital knowledge from the university that spills over to the firm's projects begets (i.e., brings about) additional knowledge in the form of scientific papers submitted for publication. |

| Abstract: | We explore the innovative performance of firms resulting from their Phase II Small Business Innovation Research (SBIR) research-funded projects in terms of the gender dynamics of the firms. Using commercialization as the relevant performance metric, we find that Phase II projects led by a female principal investigator (PI) have greater probability of being commercialized in female-owned firms than in male-owned firms. This result is consistent with the findings from other settings that females tend to perform better when working under a female supervisor. |

| Abstract: | Various forms of social learning and network effects are at work on crowdfunding platforms, giving rise to informational and payoff externalities. We use novel entrepreneur-backer data to study how these externalities shape funding dynamics, within and across projects. We find that backers decide to back a particular project based on past contributions not only to that project - as documented by prior work - but also to other contemporaneous projects - a novel result. Our difference-in-differences estimates indicate that such ‘cross-project funding dynamics’ account for 4-5% in the increase of contributions that projects generate on a daily basis. We show that recurrent backers are the main transmission channel of cross-project funding dynamics: by initiating social learning about project existence and quality, recurrent backers encourage future funding by other backers. Our results demonstrate that even though contemporaneous projects compete for funding, they jointly benefit from their common presence on the platform. We finally show that these crowdfunding dynamics stir platform growth, with important consequences for competition among platforms. |

| Abstract: | This study examined the practice of feasibility and viability studies in Uyo through a survey of a cross-section of thirty-six estate surveying and valuation firms in the area using structure questionnaire. The data gathered were analysed using frequency distribution and relative importance index. The study found that twenty-six development project failed out of the thirty-nine development projects examined. The findings also showed that development appraisal practice was not common in Uyo, since twenty-nine of the firms did not engage in the exercise frequently. It among other issues recommended mass enlightenment of the public on the benefit of development appraisal to increase the level of practice. |

| Abstract: | Variables considered in development appraisal sometimes assume character and behavioural distortions and magnitude. Thus, this study examined whether there is significant difference between predicted variable values as used by appraisers and actual values on the execution of the project. In attempt to achieve this, the study surveyed a cross section of 36 estate surveying and valuation firms’ reports and their clients in Uyo. Analysis of Variance (ANOVA) at 5% level of significant was used to confirm the difference. The study found that there is significant difference between the estimated variable values as adopted by development appraisers in their reports and the actual or realised values of such variables on execution/completion of the projects. It further revealed that development period had the highest difference between the estimated and actual period followed by interest rate adopted and cost of construction. It was suggested that henceforth, appraisers should provide their clients with an understanding of fluctuation in these variables and point out that development appraisals were prepared on assumptions of economic stability. |
