Motives, governance, and long-term performance of mergers and acquisitions in Asia

Abstract This study aims to examine the long-term performance of post-Mergers and Acquisitions (M&A) based on the motive’s category. This study also examines whether the governance at firm-level and country-level affects the relationship between motives and long-term performance of M&A. This study uses a sample of 301 completed M&A transactions of Asian companies in 11 countries from 2002 to 2012 and analyses the data using the cross-sectional moderated regression method. This study measures and categorizes M&A motives into synergy and agency categories using two alternate ways, which first using the stock market reaction data of acquirer and target at the M&A announcement period estimated by applying an event study methodology, and the second using the combination of the stock market reaction data and some accounting variables through logistic regression analysis. This study finds that synergy-motivated M&A results in significantly higher long-term performance post-M&A than agency-motivated M&A. It also proves that the positive effect of M&A motives on the long-term performance post-M&A is significantly higher when companies have better firm-level governance quality, but a similar result cannot be proved for country-level governance. This study provides a cross-country M&A study in the Asian region that has an essential role in global M&A activity in recent years. Considering the possibility of changes in company structure and environment post-M&A, this study contributes to provides an insight related to the role of the governance quality post-M&A as a monitoring tool in the realization of M&A predicted gain that can improve M&A performance.
Supramolecular biopolymeric composite materials: Green synthesis, characterization and applications

SUPRAMOLECULAR BIOPOLYMERIC COMPOSITE MATERIALS: GREEN SYNTHESIS, CHARACTERIZATION AND APPLICATIONS Tamutsiwa M. Mututuvari, B.Sc. (Honors, Chemistry) Marquette University, 2014 Macrocycles, such as crown ethers (CRs) and resorcinarenes (RESs), exhibit selective complexation of heavy metal ions and organic pollutants respectively. Consequently, they have been investigated for their suitability in adsorbing these aqueous pollutants. However, they are difficult to handle and recycle for reuse because, by themselves, they can only be fabricated in powder form. To alleviate this challenge, we developed a method to encapsulate these macrocycles into film-forming polysaccharides—cellulose (CEL) and chitosan (CS). This was achieved by using a green and recyclable solvent, an ionic liquid, to dissolve both macrocycles and polysaccharides and regenerate corresponding composites in water. Resultant composites were characterized by FTIR, UV-Visible, X-ray powder diffraction and scanning electron microscopy. These polysaccharides are attractive because they are naturally abundant, biodegradable and biocompatible. The composites retained desirable properties of their individual constituents, namely superior mechanical strength (from CEL), excellent adsorption capability for cadmium and zinc ions (from CRs and CS) and organic solutes (from RESs and CS). Specifically, increasing the concentration of CEL from 50% to 90% in [CEL+CR] resulted in almost 2X increase in tensile strength. Adding 40% benzo 15crown-5 ether (B15C5) to CS led to a 4X enhancement in the amount of cadmium ions adsorbed by [CS+B15C5]. Interestingly, RES-based composites exhibited selectivity amongst dinitrobenzene (DNB) isomers. For example, one g of [CEL+RES] adsorbed more 1,2-DNB (5.37±0.05 mol L) than 1,3-DNB (4.52±0.03 mol L) and 1,4-DNB (2.74±0.04 mol L). These results help to extend the potential applications of supramolecular composites in water remediation. We also successfully synthesized hydroxyapatite (HAp) in situ by alternately soaking [CEL+CS] composite films in calcium and phosphate salt solutions. These composites will be expected to be osteoconductive (due to HAp), thereby necessitating their use in bone tissue engineering. In another related study, we developed a simple, one step process to encapsulate an antibiotic, ciprofloxacin (CPX) in composites containing various proportional concentrations of CEL, CS, and keratin (KER). KER was found to slow down the release of CPX from the composites. These results clearly indicate that the release of CPX can be controlled by judicious adjustment of the concentrations of KER in the composites.
An Uncertain Alternating Renewal Insurance Risk Model

The claim process in an insurance risk model with uncertainty is traditionally described by an uncertain renewal reward process. However, the claim process actually includes two processes, which are called the report process and the payment process, respectively. An alternative way is to describe the claim process by an uncertain alternating renewal reward process. Therefore, this paper proposes an insurance risk model under uncertain measure in which the claim process is supposed to be an alternating renewal reward process and the premium process is regarded as a renewal reward process. Then, the paper also gives the inverse uncertainty distribution of the insurance risk process. The expression of ruin index and the uncertainty distribution of the ruin time are derived which both have explicit expressions based on given uncertainty distributions. Finally, several examples are provided to illustrate the modeling ideas.

Remote Work Aided by Conversational Agents

ABSTRACT Due to the coronavirus pandemic, remote work from home has rapidly become a necessity around the world, drastically changing the potential landscape for the future of work. Over the last couple of decades, microtask crowdsourcing has emerged as a viable means of carrying out remote online work to earn one’s living — an alternative to traditional work for a large number of people. In the aftermath of the pandemic, there is likely to be an increase in people who need to work from home due to a variety of reasons, ranging from safety and well-being to massive layoffs. However, current crowdsourcing platforms and marketplaces are not adequately optimized for worker satisfaction or engagement. There is a need for a new means of interaction that can engage the workers, support their cognitive needs, cater to their well-being – all without compromising on the quality of work being produced. Drawing inspiration from prior studies which have shown that conversational systems can improve user experiences, we investigate the feasibility of microtask crowdsourcing aided by conversational agents. Findings based on our recent research in conversational microtasking, have important implications on improving both, the subjective mental condition and objective output quality of workers. We believe that conversational agents have an important role to play in shaping how remote work can be carried out in the imminent future.

Mastitis: Havoc to dairy cattle in Mizoram

Mastitis is the widely prevalent malady of dairy cattle. The present study aimed at finding the prevalence of bovine mastitis in Mizoram and to explore the treatment options with different antibiotics after determining the etiology. Hundred animals from 18 different farms were screened using modified California Mastitis test and recorded as positive and negative based on appearance of precipitation. An overall incidence rate of mastitis was observed as 72%. The milk samples were collected from positive animals, and microbial etiology were determined using appropriate laboratory techniques. The different organisms isolated were Staphylococci , Streptococci and E. coli . Animals were grouped into three groups and treated with Ceftizoxime, Cefoperazone sodium, Cefquinome sulphate and Cefquinome sulphate. It is observed that the third group where, Cefquinome sulphate and Cefquinome sulphate used showed 100% cure. These observations necessitate the requirement of regular screening of cattle and application of preventive and control measures for mastitis.

Abstract Zygophyllum xanthoxylon and Z. fabago are two important desert plants from Zygophyllaceae, which are both widely distributed in north-western China. Here, we report the complete chloroplast genome sequences of Z. xanthoxylon and Z. fabago, which are 109,577 bp and 108,695 bp in length, respectively. The inverted repeat regions, the large single-copy region and the small single-copy region of Z. xanthoxylon are 5084 bp, 83,735 bp, and 15,674 bp in length, respectively, while those of Z. fabago are 4669 bp, 82,293 bp and 17,064 bp in length, respectively. A total of 98 genes were annotated in the genome of Z. xanthoxylon including 29 tRNA, 4 rRNA and 65 protein-coding genes, and 100 genes were annotated in the genome of Z. fabago including 31 tRNA, 4 rRNA and 65 protein-coding genes. Phylogenetic analysis showed Z. xanthoxylon clustered and Z. fabago formed a monophyletic group sister to Tetraena mongolica.
The effects of adding Gonadotropin-releasing Hormone antagonist on cycle characteristics and pregnancy rate in stimulated Intrauterine Insemination (IUI) cycle

A prospective randomised (comparative) study was conducted in the High Institute for Infertility Diagnosis and Assisted Reproductive Technologies in AL-Nahrain University, Baghdad – Iraq, from the 1 of October 2018 till 1 of September 2019 involving seventy women of infertile couples with the same inclusion and exclusion criteria. They were randomly allocated into two groupsreceiving minimal ovarian stimulation protocol (Clomiphene Citrate and Human Menopausal Gonadotropin) with IUI adding lexible GnRH antagonist protocol (Cetrorelix) to the study group. IUI was done 40-44 hours after ovulation trigger. There were no signi icant statistical variances among control and study groups in demographic characteristics concerning: age, BMI, type, duration and cause of infertility. There was no important variance in a mean day of trigger among control and study groups, 12.43 ±1.56 versus 13.11 ±1.49, at the same order (p = 0.064). The Mean number of dominant follicles was considerably greater in study groups than that of the group control, 2.40±1.03versus1. 89±0.83, respectively (p=0.025). Mean serumEstradiol of the study group was signi icantly higher than that of the control group, 478.68 ±423.61 versus 273.12 ±254.57, respectively (p = 0.016). The proportion of women with LH> 10 were signi icantly less frequent in the study group in comparisonwith the control group, 22.9%versus 68.6%, at the same order (p < 0.001). There was no important variance in mean serum Progesterone among control and study groups. There was no signi icant difference in the characteristic of the dominant follicle, ruptured versus not ruptured, (p = 0.124) on the day of IUI. The pregnancy rate was higher in the study group when compared with the control group; however, the difference in pregnancy rate doesn’t reach statistical import (p = 0.145)
Synthesis of Novel Coumarin Derivatives Bearing Phosphor Ester Motifs and Evaluation of their Antioxidant Activities

phosphoramidate, phosphoranylidenetriazene, and azaphosphole derivatives can be respectively formed when the substituted azidocoumarin 1 reacted with trialkylphosphites (TAP), dialkylphosphonates (DAP), and tris(dialkylamino)phosphines. The known triazinedione was revealed to be a side product in the reactions of carbaldehyde 1 with TAP and tris(dialkylamino)-phosphines. In the same context, when the starting coumarin 16 was allowed to react with P (III) reagents, chromen phosphoramidates and chromen phosphoric triamide derivatives were obtained via Staudinger reaction. Contrary to that pathway, phosphoranylidenetriazen chromen derivative could be isolated and identified when coumarin 16 was allowed to react with tris(diethylamino)-phosphine. The antioxidant activities of 6-newly products were evaluated. The results showed that two from the six screened compounds exhibited good antioxidant activities.

Exploring the Spatial Gradient Effect

We examined the limitations of the spatial gradient effect, or decrease in availability of objects/locations as a function of distance traveled. Across three experiments we used naming time probes to measure availability of an initial spatial location after varying the distance a protagonist traveled. The findings will be discussed in terms of the limit they place on memorybased explanations, and the need for dimensional information that is a part of situation-based explanations of comprehension.
Numerical Simulation of Moving Heat Flux during Selective Laser Melting of AlSi25 Alloy Powder

A single-layer three-dimensional model was created to simulate multi-channel scanning of AlSi25 powder in selective laser melting (SLM) by the finite element method. Thermal behaviors of laser power and scanning speed in the procedure of SLM AlSi25 powder were studied. With the increase of laser power, the maximum temperature, size and cooling rate of the molten pool increase, while the scanning speed decreases. For an expected SLM process, a perfect molten pool can be generated using process parameters of laser power of 180 W and a scanning speed of 200 mm/s. The pool is greater than the width of the scanning interval, the depth of the molten pool is close to scan powder layer thickness, the temperature of the molten pool is higher than the melting point temperature of the powder and the parameters of the width and depth are the highest. To confirm the accuracy of the simulation results of forecasting excellent process parameters, the SLM experiment of forming AlSi25 powder was carried out. The surface morphology of the printed sample is intact without holes and defects, and a satisfactory metallurgical bond between adjacent scanning channels and adjacent scanning layers was achieved. Therefore, the development of numerical simulation in this paper provides an effective method to obtain the best process parameters, which can be used as a choice to further improve SLM process parameters. In the future, metallographic technology can also be implemented to obtain the width-to-depth ratio of the SLM sample molten pool, enhancing the connection between experiment and theory.
Plant sciences for the Anthropocene: What can we learn from research in urban areas?

et al., 2019) . This requires more interdisciplinarity between ecologists and social and cultural scientists. Third, a managerial approach to nature conservation that intends to reach specific targets through planned interventions based on disciplinary scientific evidence from the biological sciences is a too narrow vision for the healing of our relationships with nature in our time of biodiversity loss and overexploitation of the planet. We need to develop new bonds with nature and work toward a new ethic and culture of stewardship for nature (e.g., Krasny & Tidball, 2015). This will require hybrid thinking at the intersections of ecology, social and cultural sciences, planning and design, social, cultural and artistic practice, ethics religion, and civil society.
A Comparative Study for Indoor Planar Surface Segmentation via 3D Laser Point Cloud Data

In recent years, point cloud data generated with RGB-D cameras, 3D lasers, and 3D LiDARs have been employed frequently in robotic applications. In indoor environments, RGB-D cameras, which have short-range and can only describe the vicinity of the robots, generally are opted due to their low cost. On the other hand, 3D lasers and LiDARs can capture long-range measurements and generally are used in outdoor applications. In this study, we deal with the segmentation of indoor planar surfaces such as wall, floor, and ceiling via point cloud data. The segmentation methods, which are situated in Point Cloud Library (PCL) were executed with 3D laser point cloud data. The experiments were conducted to evaluate the performance of these methods with the publicly available Fukuoka indoor laser dataset, which has point clouds with different noise levels. The test results were compared in terms of segmentation accuracy and the time elapsed for segmentation. Besides, the general characteristics of each method were discussed. In this way, we revealed the positive and negative aspects of these methods for researchers that plan to apply them to 3D laser point cloud data.
A Review of Intrusion Detection Systems Using Machine and Deep Learning in Internet of Things: Challenges, Solutions and Future Directions

The Internet of Things (IoT) is poised to impact several aspects of our lives with its fast proliferation in many areas such as wearable devices, smart sensors and home appliances. IoT devices are characterized by their connectivity, pervasiveness and limited processing capability. The number of IoT devices in the world is increasing rapidly and it is expected that there will be 50 billion devices connected to the Internet by the end of the year 2020. This explosion of IoT devices, which can be easily increased compared to desktop computers, has led to a spike in IoT-based cyber-attack incidents. To alleviate this challenge, there is a requirement to develop new techniques for detecting attacks initiated from compromised IoT devices. Machine and deep learning techniques are in this context the most appropriate detective control approach against attacks generated from IoT devices. This study aims to present a comprehensive review of IoT systems-related technologies, protocols, architecture and threats emerging from compromised IoT devices along with providing an overview of intrusion detection models. This work also covers the analysis of various machine learning and deep learning-based techniques suitable to detect IoT systems related to cyber-attacks.
General Modeling Language Supporting Model Transformations of MBSE (Part 2)

With the increasing complexity of systems, model‐based systems engineering (MBSE) has attracted increasing attention in the industry. MBSE formalizes the whole lifecycles of products using models based on systems engineering aiming to improve the development efficiency of complex systems. Traditionally, MBSE approaches require many modeling languages in each phase of the entire lifecycle. Different syntax between such languages leads to difficulty in supporting an integrated description of transformations between models and data. Thus, it is challenged to utilize a general language to describe model formalism and transformation for architecture‐driven technology and code generation in one MBSE tool. In this paper, a multi‐architecture modeling language called Karma (introduced in Paper Part 1) is proposed to support the model transformations including architecture‐driven technology and code generation implementations in one modeling tool. Finally, from one auto‐braking case of an autonomous‐driving system, we find the availability of the Karma language supporting architecture‐driven technology and code generation is verified.
