About

Dr. Jun Wang is a professor in the Department of Neuroscience & Experimental Therapeutics at Texas A&M University College of Medicine. His research focuses on the role of basal ganglia circuitry in the neurobiological basis of neuropsychiatric diseases, including alcohol use disorder, opioid use disorder, and Alzheimer's disease. His lab investigates synaptic plasticity and circuit-specific alterations in the dorsal striatum, particularly how alcohol and opioids induce aberrant plasticity in neuronal ensembles and how these changes contribute to pathological behaviors such as addiction and relapse. Dr. Wang's work employs techniques such as slice electrophysiology, optogenetics, viral and animal transgenics, and activity-dependent labeling approaches to explore circuit mechanisms underlying compulsive drinking and drug reinforcement. His research also extends to understanding how striatal dysfunction relates to Alzheimer's disease, especially in the context of motor deficits and cholinergic activity. He participates in graduate training within the Medical Science Ph.D. program, the Interdisciplinary Program in Neuroscience, and the Interdisciplinary Toxicology Program at Texas A&M University.

  ABSTRACT Using a comprehensive database of U.S. internal auditor job postings, we find that firms are about 10 percent more likely to post an internal auditor job after the revelation of accounting and operational failures. Also, the demand for internal auditors is stronger when a failure is more severe. Among firms posting internal auditor jobs, firms demand higher-quality internal auditors in response to a failure compared with when there has not been a recent failure. We find evidence of internal audit demand spillovers through connected directors, which helps mitigate concerns that the primary results are due to replacing internal auditors that recently left or due to endogenous links between hiring internal auditors and failure revelations. Overall, our evidence suggests that firms demand internal auditors to help ensure high-quality financial reporting and effective operations. JEL Classifications: G34, J23, M41, M42.

• An empirical analysis of the effects of the Dodd–Frank Act on determinants of credit ratings

  Journal of Business Finance &amp Accounting · 2023-03-19 · 9 citations

  Abstract We study the effects of the Dodd–Frank Act (“Dodd–Frank”) on determinants of credit ratings. We predict that the increase in regulatory oversight and litigation risk prompted by Dodd–Frank, as well as requirements for improved disclosures and governance, motivated credit rating agencies (CRAs) to increase the reliance on verifiable quantitative fundamental information in determining ratings. We find that the power of firm fundamentals in explaining credit ratings increases significantly after Dodd–Frank. Furthermore, we find that the greater reliance on quantitative firm fundamentals at least partially drives the improvement in credit ratings’ ability to predict future defaults. Collectively, our evidence suggests that Dodd–Frank incentivizes CRAs to use more quantitative information in making rating decisions, which improves credit rating quality.

  KEY MESSAGE: This review provides a comprehensive atlas of QTLs, genes, and alleles conferring resistance to 28 important diseases in all major soybean production regions in the world. Breeding disease-resistant soybean [Glycine max (L.) Merr.] varieties is a common goal for soybean breeding programs to ensure the sustainability and growth of soybean production worldwide. However, due to global climate change, soybean breeders are facing strong challenges to defeat diseases. Marker-assisted selection and genomic selection have been demonstrated to be successful methods in quickly integrating vertical resistance or horizontal resistance into improved soybean varieties, where vertical resistance refers to R genes and major effect QTLs, and horizontal resistance is a combination of major and minor effect genes or QTLs. This review summarized more than 800 resistant loci/alleles and their tightly linked markers for 28 soybean diseases worldwide, caused by nematodes, oomycetes, fungi, bacteria, and viruses. The major breakthroughs in the discovery of disease resistance gene atlas of soybean were also emphasized which include: (1) identification and characterization of vertical resistance genes reside rhg1 and Rhg4 for soybean cyst nematode, and exploration of the underlying regulation mechanisms through copy number variation and (2) map-based cloning and characterization of Rps11 conferring resistance to 80% isolates of Phytophthora sojae across the USA. In this review, we also highlight the validated QTLs in overlapping genomic regions from at least two studies and applied a consistent naming nomenclature for these QTLs. Our review provides a comprehensive summary of important resistant genes/QTLs and can be used as a toolbox for soybean improvement. Finally, the summarized genetic knowledge sheds light on future directions of accelerated soybean breeding and translational genomics studies.

• The Audit Quality Effects of Small Audit Firm Mergers in the United States

  SUMMARY Increased audit regulation, coupled with reports of frequent mergers among smaller audit firms, creates a dynamic environment in which to assess changes in the U.S. audit market. We examine the audit quality consequences of audit firm mergers between small audit firms that audit public clients, a topic about which little is known. Using a sample of small audit firms each involved in a single merger during 2004–2016, we find consistent evidence that post-merger audit quality decreases when PCAOB-identified audit deficiencies and audit fees are used as proxies for audit quality. In addition, we find weak evidence of lower post-merger audit quality when examining discretionary accruals, and no conclusive post-merger audit quality effect for the probability of misstatements. Overall, our findings provide evidence regarding the audit quality consequences of some small audit firm mergers in the United States. Data Availability: Data are available from the public sources cited in the text. JEL Classifications: M42.

• Do <scp>PCAOB</scp> Inspections of Foreign Auditors Affect Global Financial Reporting Comparability?*

  ABSTRACT This study investigates whether PCAOB inspections of foreign auditors affect global financial reporting comparability. Foreign auditors may adjust audit methodologies to address PCAOB inspection findings, which could affect financial reporting of local clients. Exploiting both within‐ and cross‐country variation in PCAOB inspections, we predict and find that non‐US‐listed foreign companies' financial reporting becomes more comparable to their US and non‐US industry peers after their auditors undergo an initial inspection. However, there is a decrease in comparability compared to local peers whose auditors have not been inspected. Subsample tests suggest that the improvement in comparability is driven by (i) auditors that satisfactorily address deficiencies and (ii) auditors that do not publicly push back against deficiencies. The effects are dampened after local audit regulators begin inspection programs. Overall, our evidence suggests that the PCAOB international inspection program affects audit methodologies of inspected auditors in a consistent way, improving comparability across jurisdictions. The improved comparability implies that the PCAOB international inspection program may unintentionally help meet accounting regulators' goals of cross‐country financial reporting convergence, which potentially promotes efficient cross‐country capital allocation.
