Wealth Effects Of Bank Mergers And Acquisitions In Asian Emerging Markets
Through analysis of stock responses to two different types of banking M&A deals, specifying M&A and diversifying M&A, we find that specifying M&A deals incur positive cumulative abnormal returns (CAR) in both two-day and three-day windows without controlling for firm size. Diversifying M&A deals incur positive CAR in two different event windows. However, the differences between the two windows are not statistically significant. Contrary to previous studies on M&A in the banking industry of developed markets, the results of our study indicate that markets do not distinguish among various types of M&A deals in the banking industry around the date of announcement. Diversifying M&A generate positive three-day CARs but they are not significantly better than specifying M&A
Silent messages in negotiations: The role of nonverbal communication in cross-cultural business negotiations
This study specifically explored the perceived importance of the following nonverbal factors in the negotiation process: proxemics (location and negotiation site), physical arrangement (seating and furniture arrangement), and kinesics (eye contact, facial expressions and gestures). The participants are professional business negotiators of different nationalities. The findings show that the negotiators\u27 perception about the three factors and their roles in negotiation are consistent with the nonverbal communication literature
Comparison of BISAP, Ranson, MCTSI, and APACHE II in Predicting Severity and Prognoses of Hyperlipidemic Acute Pancreatitis in Chinese Patients
In recent years, with the developing of living standard, hyperlipidemia becomes the second major reason of acute pancreatitis. It is important to predict the severity and prognosis at early stage of hyperlipidemic acute pancreatitis (HLAP). We compared the BISAP, Ranson, MCTSI, and APACHE II scoring system in predicting MSAP and SAP, local complications, and mortality of HLAP. A total of 326 diagnosed hyperlipidemic acute pancreatitis patients from August 2006 to July 2015 were studied retrospectively. Our result showed that all four scoring systems can be used to predict the severity, local complications, and mortality of HLAP. Ranson did not have significant advantage in predicting severity and prognosis of HLAP compared to other three scoring systems. APACHE II was the best in predicting severity of HLAP, but it had shortcoming in predicting local complications. MCTSI had outstanding performance in predicting local complications, but it was poor in predicting severity and mortality. BISAP score had high accuracy in assessment of severity, local complications, and mortality of HLAP, but the accuracy still needs to be improved in the future
Correlation of Body Mass Index and Waist-Hip Ratio with Severity and Complications of Hyperlipidemic Acute Pancreatitis in Chinese Patients
Hyperlipidemic acute pancreatitis (HLAP) is characterized by critical condition and high recurrence rate compared with non-HLAP. We conducted this study to investigate the value of body mass index and waist-hip ratio in predicting severity and local complications in HLAP. 96 patients with HLAP were categorized by body mass index and waist-hip ratio, respectively. According to the body mass index, they were divided into 3 groups, including normal weight, overweight, and obesity. According to the waist-hip ratio, they were divided into central obesity group and no central obesity group. The body mass index and waist-hip ratio were compared in severity, local complications, and systematic complications of HLAP, using chi-square test and Monte Carlo simulations. The body mass index and waist-hip ratio were correlated with the severity of acute pancreatitis (MAP, MSAP, and SAP), respiratory failure, and circulatory failure in HLAP (p<0.05), but not correlated with the local complications (walled-off necrosis, pancreatic abscess, and pancreatic pseudocyst), renal failure, and gastrointestinal bleeding.The body mass index and waist-hip ratio are valuable in predicting severity and complication in HLAP. We demonstrated that obese patients had an increased risk of developing more serious condition and more complications in HLAP
Large expert-curated database for benchmarking document similarity detection in biomedical literature search
Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
Revenue enhancement and wealth effects of mergers and acquisitions in Asian emerging markets
Revenue enhancement and value creation are core issues of mergers and acquisitions (M&A). Revenue enhancing synergy associated with cross-industry M&A is supported by Asian emerging markets. Both within-industry M&A and cross-industry M&A deals realise significant positive abnormal returns. The difference between the two categories of M&A is statistically significant in a three-day window, but not statistically significant in a two-day window. Information leakages may be driving the larger valuation effects because a three-day window includes one day before the announcement date. Since large firms tend to diversify their business, the result that cross-industry M&A deals realise lower abnormal returns than within-industry may be driven by the firm size effect.revenue enhancement; company acquisitions; abnormal returns; SIC; Standard Industry Code; Standard Industrial Classification; wealth; Asia; emerging markets; value creation; within-industry mergers; cross-industry mergers; statistical significance; information leakages; valuation effects; firm size; merger announcements; Indonesia; Thailand; Singapore; Philippines; Malaysia; India; Taiwan; South Korea; Hong Kong; China; revenue management.
A Linear-Correction Algorithm for Quasi-Synchronous DFT
Spectral leakage in the harmonic measured by quasi-synchronous DFT (QSDFT) is mainly due to short-range leakage caused by deviation in the signal frequency. By analysing the short-range-leakage characteristic of QSDFT, a linear-correction algorithm (LCQS) for QSDFT’s harmonic-analysis results is proposed. LCQS contains two linear-correction equations: an amplitude-correction equation and an initial-phase-angle-correction equation. The former is constructed by the least-squares method, whereas the latter is generated based on the linear error characteristic of the QSDFT harmonic phase. Simulation and experimental results indicate that this proposed algorithm can efficiently increase the accuracy of the harmonic parameters over a wide frequency range by minimizing the short-range spectral leakage
