The Interaction Effect of Heuristic Representation on Initial Public Offering Anomaly: Evidence from Flipping Activity

This study examines the impact of the heuristic representation on IPO anomaly in the context of an emerging market from January 2006 to December 2016. Models consist of multiple regression has been evaluated. Our results show: firstly, the distribution of initial return, oversubscription ratio, firm age, offer period, firm size, heuristic representation, and flipping activity are positively skewed; Secondly, the oversubscription ratio has a positive relationship with flipping activity. This is because higher demand makes investors flip more to liquidate the IPO on the first trading day. In contrast, firm size has a negative relationship with flipping activity. A larger IPO firm is more stable in terms of performance, and less risky in terms of business operation; Thirdly, heuristic representation influences the relationship between oversubscription ratio and flipping activity; Lastly, this study dispels the notion that investors are active in subsequent trading but not necessarily obtain a profit from the liquidation. This study extends earlier work by examining the interaction effect of heuristic representation to the flipping activity in an emerging market

Ability, motivation and opportunity (AMO)-enhancing HRM practices and corporate environmental citizenship: the mediation effect of organizational ethical climate

Ability, Motivation and Opportunity (AMO)-enhancing is essential for the effective implementation of corporate environmental citizenship. However, previous studies neglect the link between AMO-enhancing HRM practices and corporate environmental citizenship. This has motivated the paper studies the influence of AMO-enhancing HRM practices on corporate environmental citizenship via the mediating role of organizational ethical climate. This study employed a quantitative approach in the form of survey questionnaires. Survey questionnaires were collected from 200 construction companies and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results revealed that ability and opportunity-enhancing HRM practices were found to positively influence corporate environmental citizenship. Motivation-enhancing HRM practices were insignificant in this regard. Similarly, organizational ethical climate did not prove to mediate the relationship between AMO-enhancing HRM practices and corporate environmental citizenship. Therefore, construction companies should invest heavily in ability and opportunity-enhancing HRM practices to pursue corporate environmental citizenship. Instead, construction companies can abandon motivation-enhancing HRM practices and organizational ethical climate if they have limited funds to improve corporate environmental citizenship. Ultimately, policy makers should use these findings to create strategies as guidance for the construction industry to achieve corporate environmental citizenship

Employee perception of whistleblowing in the workplace: A systematic bibliometric review

This paper systematically reviews employee perceptions of whistleblowing in the workplace. The theoretical foundation of this paper lies in the study of whistleblowing as an integral part of internal control systems for fraud prevention in organizations. About 806 publications in the Web of Science database were analyzed using a bibliometric approach entailing bibliographic coupling and co-word analysis. The review explores the study of whistleblowing, which is constantly rising as a result of the fact that many countries are strengthening their organizational whistleblowing systems. It is anticipated that more publications will be generated in the future years. The empirical results of this study indicate that a positive corporate working environment should be promoted from the top down and cultivated horizontally. The findings of this study, which were based on actual evidence, are helpful from a pragmatic point of view. Specifically, companies would need to foster a corporate climate that makes it easier for employees to report any probable or seen misconduct to higher authorities. This paper presents a novel knowledge structure by mapping employee perceptions regarding whistleblowing in the context of minimizing ongoing wrongdoings in organizations based on bibliometric analysis. Moreover, future studies should address organizational culture or the role of leadership in employee whistleblowing

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

The Impact of Global Financial Crisis on IPO Underpricing in Malaysian Stock Market

This study examines the impact of the Global Financial Crisis (GFC) on Initial Public Offering (IPO) underpricing in the context of an emerging market from January 2006 to December 2011. Models consist of hierarchical and dummy variable regressions have been evaluated. Our results show, firstly, by comparison between the pre-GFC, GFC and post-GFC periods, it can be observed that IPOs initial returns (offer-to-close) are generally lower due to the crisis. Secondly, IPO underpricing provides an average of 17-25% of initial returns in the pre-GFC period, 1-3% during GFC period, and 3-7% in the post-GFC period. Thirdly, the financial crisis does not act as a moderator that worsens the relationship between underpricing of IPO and oversubscription ratio. Lastly, this study dispels the notion that investors should totally shun IPO during crisis period as there are still positive initial returns among the new issues. To the authors' knowledge, this is the first study on the impact of the GFC on IPO underpricing in Malaysia

The High-Low Intraday Performance of Initial Public Offerings during Global Financial Crisis : Evidence from Malaysian Stock Market

This study investigates the high-low intraday Performance of Initial Public Offering (IPO) during Global Financial Crisis (GFC) from January 2006 to December 2011.  Models comprise of hierarchical and dummy variable regressions are evaluated. Our results show: Firstly, it can be observed that intraday IPOs performance are generally lower due to the GFC; Secondly, investors receive 7 to 30 percent IPO intraday returns on average in the first trading day of pre-GFC, -5 to 11 percent during GFC, and -4 to 14 percent in the post-GFC; and thirdly, the GFC does not act as a moderator that worsens the relationship between intraday IPO performance and oversubscription ratio. As for implication, this study dispels the notion that investors should totally shun IPO during GFC period as there are still positive intraday returns among the IPOs. &nbsp

Impact of Founder on the IPO Flipping Activity during Pre and Post-Global Financial Crisis

This study examines the impact of the founder on the IPO flipping activity in the Malaysian stockmarket, especially the Main and ACE Market, across the Global Financial Crisis (GFC) periodfrom January 2006 to December 2016. Multiple regression models have been used to evaluate the interaction of the founder and other independent variables. Using three sub-periods, namely pre- GFC, GFC, and Post-GFC, our results show: Firstly, the founder by itself does not have any impact on flipping activity. However, the interaction of founder and oversubscription ratio reduces flipping activity in the pre-crisis period. Secondly, the interaction of founder and firm age is significant during the GFC period. Thirdly, in post-GFC, the interaction between founder-firm age, founder-offer period are essential factors. Overall, it is found that firm age and IPO offer period have an impact on flipping activity in the Main and ACE Market

Macroeconomic determinants on Malaysian stock market performance

Macroeconomic variables applied in this investigation comprise inflation rate, exchange rate, crude oil price, foreign direct investment, unemployment rate whereas Malaysian share market performance is the dependent variable. The secondary data was extracted from various websites from 2011 to 2020 on a quarterly basis. Various tests are used to test in the EViews 10. The results show that exchange rate along with crude oil price have a significant relationship on Malaysian share market performance. However, this research also discovered that inflation rate, foreign direct investment as well as unemployment rate have least impact on Malaysian share market performance

Quantification of hepatic steatosis in chronic liver disease using novel automated method of second harmonic generation and two-photon excited fluorescence

Abstract The presence of hepatic steatosis (HS) is an important histological feature in a variety of liver disease. It is critical to assess HS accurately, particularly where it plays an integral part in defining the disease. Conventional methods of quantifying HS remain semi-quantitative, with potential limitations in precision, accuracy and subjectivity. Second Harmonic Generation (SHG) microscopy is a novel technology using multiphoton imaging techniques with applicability in histological tissue assessment. Using an automated algorithm based on signature SHG parameters, we explored the utility and application of SHG for the diagnosis and quantification of HS. SHG microscopy analysis using GENESIS (HistoIndex, Singapore) was applied on 86 archived liver biopsy samples. Reliability was correlated with 3 liver histopathologists. Data analysis was performed using SPSS. There was minimal inter-observer variability between the 3 liver histopathologists, with an intraclass correlation of 0.92 (95% CI 0.89–0.95; p < 0.001). Good correlation was observed between the histopathologists and automated SHG microscopy assessment of HS with Pearson correlation of 0.93: p < 0.001. SHG microscopy provides a valuable tool for objective, more precise measure of HS using an automated approach. Our study reflects proof of concept evidence for potential future refinement to current conventional histological assessment
