Research summary: Governments in emerging economies often use institutional intermediaries to promote entrepreneurship, and bridge the void between ventures and public funding. While prior literature describes what institutional intermediaries do, it leaves open how intermediaries support different types of entrepreneurs. By comparing science park and non‐science park firms in Beijing and across China, we distinguish which entrepreneurs benefit from certification versus capability‐building through the introduction of two new constructs: skill adequacy and context relevance. Broadly, our study adds insights at the nexus of emerging economies and entrepreneurship research, and to the tie formation and institutional intermediaries literatures. Managerial summary: A key dilemma facing entrepreneurs is how to finance their ventures. While entrepreneurs in developed economies can seek VC or angel investment, entrepreneurs in emerging economies often need to pursue potential government funding opportunities. Our study highlights three strategies for acquiring government funding. Well‐connected entrepreneurs can leverage their political ties to acquire such funding. Less‐connected entrepreneurs can leverage science parks that in emerging markets are designed to help governments to identify promising ventures. For returnees whose ample experience abroad may not fit with local ways of doing business, gaining science park admission can certify quality and so ease the path to government funding. For technically skilled local entrepreneurs who lack business skills, science parks can help build such skills, which then ease the path to government funding.

This study explores the feasibility of an entirely satellite remote sensing (RS)‐based hydrologic budget model for a ground data‐constrained basin, the Rufiji basin in Tanzania, from the balance of runoff (Q), precipitation (P), storage change (ΔS), and evapotranspiration (ET). P was determined from the Tropical Rainfall Measuring Mission, ΔS from the Gravity Recovery and Climate Experiment, and ET from the Moderate Resolution Imaging Spectroradiometer, the surface radiation budget, and the Atmosphere Infrared Radiation Sounder. Q was estimated as a residual of the water balance and tested against measured Q for a sub‐basin of the Rufiji (the Usangu basin) where ground measurements were available (R2 = 0.58, slope = 1.9, root mean square error = 29 mm/month, bias = 14%). We also tested a geographical information system (GIS)‐driven (ArcCN‐runoff) runoff model (R2 = 0.64, slope = 0.43, root mean square error = 39 mm/month). We conducted an error propagation analysis from each of the model's hydrologic components (P, ET, and ΔS). We find that the RS‐based model amplitude is most sensitive to ET and slightly less so to P, whereas the model's seasonal trends are most sensitive to ∆S. Although RS–GIS‐driven models are becoming increasingly used, our results indicate that long‐term water resource assessment policy and management may be more appropriate than ‘instantaneous’ or short‐term water resource assessment. However, our analyses help develop a series of tools and techniques to progress our understanding of RS–GIS in water resource management of data‐constrained basins at the level of a water resource manager.

In this paper, we explore the impact of dietary deprivation, where spiders are provided diets missing one or more of the amino acids, on the properties of the spider dragline silk spun after one month on the diet. Cohorts of female N. clavipes spiders were selected for diets deprived of alanine (Ala) and glycine (Gly), arginine (Arg), leucine (Leu), or tyrosine (Tyr), and their silk was harvested twice weekly during the one-month course of the diet. Significant mechanical differences are observed after as little as 6 days on the diet. Utilizing conventional tensile testing methods, single fibers were strained to break so as to study the influence of diet on the stress/strain properties. Diets deprived of Ala and Gly appear to most directly impact the load-bearing foundation of dragline silk. Diets deprived of Arg, Tyr, and possibly Leu reduce the strength of the silk, and diets missing Tyr and Leu reduce the strain-to-failure. Observations obtained from ESEM photos of the fracture interfaces after tensile testing illustrate the fracture mechanics of spider silk. Both solid-state NMR and amino acid analysis of the digested protein suggest, however, that the relationship between diet and amino acid incorporation into the silk fiber is not straightforward.

An implicit assumption in institutional theory is that more certifications improve a venture’s likelihood for success. However, under certain conditions, we argue more certifications may be detrimental to the venture’s performance. We advance this notion by examining both who is doing the certification and, in turn, what information is revealed to others through the certification. Our study advances two new constructs based on varying instances of follow-on certification: certification broadening, where the initial and follow-on certifiers are different institutions, and certification redundancy, where the initial and follow-on certifiers are the same institution. By studying sequences of certification in the U.S. Small Business Innovation Research federal and state programs, we find that certification broadening generally increases a firm’s ability to acquire private resources, whereas certification redundancy generally decreases a firm’s ability to acquire private resources. This study advances a more dynamic view of certification within institutional theory—namely, when we disaggregate sequences of certifications, we are able to better ascertain when certification helps a venture and when it does not.

A changing generation mix and growing demand for carbon-free electricity will almost certainly require dramatic changes in the infrastructure and topology of the electricity system. Rather than build new lines, one way to minimize social opposition and regulatory obstacles is to increase the capacity of existing transmission corridors. In addition to upgrading the capacity of high-voltage alternating current (HVAC) lines, we identify a number of situations in which conversion from HVAC to high-voltage direct current (HVDC) is the least-cost strategy to increase the capacity of the corridor. If restricted to the existing right-of-way (ROW), we find DC conversion to be the least-cost, and in some cases the only, option for distances of >200 km or for increases of >50% capacity. Across all configurations analyzed, we assess HVDC conversion to be the lower-cost option at >350 km and >50% capacity increases. While we recognize that capacity expansion through HVDC conversion may be the optimal solution in only some situations, with future improvements in the cost and performance of solid-state power electronics, conversion to HVDC could be attractive in a growing set of circumstances.
