J.L. Andersen proved that there is 5-torsion in the bottom nonvanishing homology group of the simplicial complex of graphs of degree at most two on seven vertices. We use this result to demonstrate that there is 5-torsion also in the bottom nonvanishing homology group of the matching complex M14 on 14 vertices. Combining our observation with results due to Bouc and to Shareshian and Wachs, we c...

We determine all hyperbolic 3-manifolds M admitting two toroidal Dehn fillings at distance 4 or 5. We show that if M is a hyperbolic 3manifold with a torus boundary component T0, and r, s are two slopes on T0 with ∆(r, s) = 4 or 5 such that M(r) and M(s) both contain an essential torus, then M is either one of 14 specific manifolds Mi, or obtained from M1, M2, M3 or M14 by attaching a solid tor...

Social Incentives Matter: Evidence from an Online Real Effort Experiment Contributing to a social cause can be an important driver for workers in the public and nonprofit sector as well as in firms that engage in Corporate Social Responsibility activities. This paper compares the effectiveness of social incentives to financial incentives using an online real effort experiment. We find that soci...

Neddylation promotes the process of ubiquitination, which plays a critical role in the degradation of numerous proteins, including cell cycle and apoptosis regulators. In our previous study, an increase in neddylation was identified in melanoma cell lines. In the present study, the upregulation of neddylation was detected in melanoma tissues which confirmed the results of our previous study on ...

We examine the causal impact of financial analysts on firms’ socially responsible activities. Relying on brokerage closures and mergers as natural experiments which generate exogenous changes in analyst coverage, our Difference-in-Differences estimator indicates that a reduction in analyst coverage causes firms to engage more aggressively in irresponsible behavior, especially in the dimensions ...

We recall that it is a famous result due to Harris, Mumford and Eisenbud thatMg is of general type for g ≥ 24 (cf. [HM], [H1], [EH]). On the other hand, a classical theorem due to Severi saysMg is unirational for g ≤ 10 (see [AC1] for a modern exposition). Similar results for higher g were proved in the 1980’s: Sernesi showed that M12 is unirational (cf. [Se]), then Chang and Ran settled the un...

We show that investors derive utility from non-pecuniary characteristics of investments by studying impact funds, defined as venture or growth equity funds with dual objectives of generating financial returns and positive externalities. Impact funds earn internal rates of return that are 4.7% less than traditional VC funds in reduced form regressions. Based on estimates of a willingness to pay ...

The study employs modified interactive models and lead-lag models to investigate the correlation between corporate social performace (CSP) and financial performance (CFP) of listed companies in China. The samples are 1228 in both 2005 year and 2006 year, 1251 in the period of 20052006, and 1577 in both 2009 year and 2010 year, 1603 in the period of 2009-2010 year. The serious empirical research...

Research on climate change suggests that small improvements in the “sustainability” of buildings can have large effects on greenhouse gas emissions and on energy efficiency in the economy. This paper analyzes the economics of “green” building. First, we analyze a panel of office buildings certified by independent rating agencies, finding that large recent increases in the supply of green buildi...

Determinations were made for corn (Zea mays L., WF9-Tms x M14) mitochondria of the stoichiometric relationship between K(+) transport and bond energy produced in respiration (K(+)/ approximately ratio). With inward pumping of potassium acetate activated by NADH oxidation, the initial rate of K(+) transported into the sucrose inaccessible space varied between 0.58 and 0.97 K(+)/ approximately , ...
