However, female participants experience no benefit from exposure to male or female venture capitalists (VCs), which appears related to a reduced propensity to reach out to VCs to whom they were exposed. Our results therefore also demonstrate gender-based differences in the degree to which increased exposure to investors can address networking frictions in venture capital.","PeriodicalId":48380,"journal":{"name":"Journal of Financial and Quantitative Analysis","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135904722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some studies have indicated the cytotoxic effects of vanadyl oxide sulfate (VOSO4). This study aimed to evaluate the anti-cancer effect of VOSO4 in the treatment of MCF-7 cell lines.</p><p><strong>Materials and methods: </strong>The MCF-7 cell line was treated with different concentrations of VOSO4 for 24 and 48 hours. Cell death was measured using the MTT assay. The cell apoptosis rate was measured using Annexin V/Propidium Iodide assay through flow cytometry. Also, the expression levels of p53, P21, Caspase8, superoxide dismutase type 1 (SOD1), Sod2, and Bcl2 mRNAs were assessed, and Western blotting was performed for Sod1 protein.</p><p><strong>Results: </strong>The results showed that the half-maximal inhibitory concentration (IC50) for VOSO4 was 25 and 20 μg/ml for 24 and 48 hours, respectively. Indeed, VOSO4 has dose-dependent cytotoxic effects on the MCF-7. Also, after exposure to VOSO4 for 24 hours, cell apoptosis reached 52% compared with untreated cells. Moreover, after 24 hours of exposure to VOSO4 with IC50 concentration, the expression of p53, P21, Caspase8, Sod1, and Sod2 mRNAs increased (P0.05), and the expression of Bcl2 mRNA was decreased (P0.05). Also, the Western blotting revealed Sod1 protein level markedly increased following exposure to VOSO4 (P0.05).</p><p><strong>Conclusion: </strong>Our results demonstrated that VOSO4 has an apoptotic and cytotoxic effect on BC cells.

Our estimates, based on tariff reductions following multinational trade agreements, suggest that a hypothetical 10% reduction of all upstream tariffs would increase downstream investment by 4% to 6%. This estimate is not explained by decreasing uncertainty and stems from tariff reductions for homogeneous and low-R&amp;D inputs, consistent with the investment response resulting from cost reductions rather than superior foreign technology embodied in imported inputs. Evidence from an instrumental variable estimation using the sudden increase in Chinese import penetration suggests that import competition also increases downstream investment.","PeriodicalId":48380,"journal":{"name":"Journal of Financial and Quantitative Analysis","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135571832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose a particle Markov Chain Monte Carlo framework with a novel filtering approach and illustrate our method by estimating index option pricing models. Estimates of variance risk premiums, variance mean reversion, and higher moments differ from the literature. We show that these differences are due to the composition of the option sample. Restricting the option sample’s maturity dimension has the strongest impact on parameter inference and option fit in these models.","PeriodicalId":48380,"journal":{"name":"Journal of Financial and Quantitative Analysis","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136066002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrary to conventional wisdom, we find that firms with higher levels of board–CEO trust exhibit poor M&amp;A performance. High trust is associated with low acquisition announcement returns, long-term stock return performance, and post-deal operating performance. This negative effect of board–CEO trust is more pronounced among acquiring companies prone to agency problems. Our results suggest that, in the institutional setting of corporate boards, high trust can be too much of a good thing.","PeriodicalId":48380,"journal":{"name":"Journal of Financial and Quantitative Analysis","volume":"453 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136066974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
