Reduction Of Uncertainty

The industry of private equity and leveraged buyout has been, since its beginnings, subject to several chapters of bubbles and busts, the majority of whom are initiated under similar circumstances (excess of liquidity, junk debt and mimetic behavior).The Islamic finance is a financial system that complies with the rules of the Sharia Law, and which naturally allows the achievements of purposes of Sharia, such as protection of property and capital, fair wealth distribution, reduction of uncertainty and speculation, to name a few.From this perspective, this paper discusses the capacity of Islamic finance to help prevent some factors that trigger financial crises in the leveraged buyout market and to accomplish the intended purposes through this asset class.In the first part of this paper, the authors try to break down some of these common factors that trigger or catalyze the economic booms of the leverage buyout industry, and propose a framework to visualize their effects through an agent-based Simulation program. The second part of the paper describes how Islamic economic principles constitute brakes to some distortions and excesses in the market, in such a way that the probability of occurrence of a boom decreases drastically. Finally, these Islamic features are added up to the simulation to provide a comprehensive benchmark.

Purpose – The purpose of this paper is to fill the following research gaps. First, few studies have examined isomorphic behavior of multinational corporations (MNCs) with respect to foreign subsidiary staffing. Second, the adoption by an MNC of its internally preferable practices, which is referred to as internal mimetic behavior, has been less extensively investigated when compared with the imitation of practices adopted by a large number of peer firms. Lastly, factors that facilitate internal mimetic behavior have not been extensively explored. Design/methodology/approach – This study hypothesizes that internal mimetic behavior is affected by both formal and informal institutional distance. The hypotheses are tested using the panel data set that consists of 3,981 foreign subsidiaries of Japanese MNCs. Findings – This study finds that as the formal institutional distance between the host country and the home country increases, MNCs are more likely to adopt internal mimetic behavior. Furthermore, it demonstrates that as the informal institutional distance increases, the likelihood that MNCs adopt internal mimetic behavior decreases. Practical implications – This study suggests that MNCs need to consider the consequences of internal mimetic behavior when they adopt it without having economic rationale. It also suggests that when uncertainty can be mitigated, MNCs should avoid internal mimetic behavior. Originality/value – This study fills the aforementioned research gaps by examining what factors facilitate internal mimetic behavior. It suggests that both economic rationale and isomorphic behavior need to be considered to advance an understanding of foreign subsidiary staffing.

Traditionally, the international market selection is a systematic process, based on predefined criteria. This process is, however, very time- and cost-consuming, and only a small number of firms have sufficient resources to do it. So, according to the Uppsala Model, firms tend to internationalize to the closest markets (psychic distance), managing uncertainty in a very gradual process based on experiential knowledge. The second-hand knowledge that flows in the firm's network could help firms select the market, helping them to expand gradually. Independently from the source (experiential or second hand), knowledge seems to be a mandatory resource to internationalize. However, a lot of firms imitate other firms' behavior, selecting the international market according to others' selections, believing that they must have superior information. In this situation, firms could imitate the leader (a successful firm) or the herd (a big number of firms). This international market selection is not based on knowledge; it is a mimetic process.

Mimetic Behavior

Currently, researchers are looking for nanomaterials with peroxidase-like activity to replace natural peroxidase enzymes. For this purpose, WS2 quantum dots (WS2 QDs) were synthesized via a solvothermal method, which improved the mimetic behavior. The resulting WS2 QDs with a size of 1–1.5 nm had a high fluorescence emission, dependent on the excitation wavelength. WS2 QDs with uniform morphology showed a high catalytic effect in destroying H2O2. The peroxidase-like activity of synthesized nanostructures was studied in H2O2 chemical and electrochemical reduction systems. The mimetic effect of WS2 QDs was also shown in an H2O2–rhodamine B (RB) chemiluminescence system. For this aim, a stopped-flow chemiluminescence (CL) detection system was applied. Also, in order to confirm the peroxidase-like effect of quantum dots, colorimetry and electrochemical techniques were used. In the enzymatic reaction of glucose, H2O2 is one of the products which can be determined. Under optimum conditions, H2O2 can be detected in the concentration range of 0–1000 nmol·L−1, with a detection limit of 2.4 nmol·L−1. Using this CL assay, a linear relationship was obtained between the intensity of the CL emission and glucose concentration in the range of 0.01–30 nmol·L−1, with a limit of detection (3S) of 4.2 nmol·L−1.

Mimetic Behavior

Anti-predator mechanisms in snakes are diverse and complex, including mimetic behavior. Some snakes triangulate their head, probably mimicking other more dangerous snakes. However, there is a lack of studies that demonstrate the effectiveness of this behavior with natural predators. The aim of this study was to verify, using artificial snakes, if snakes with triangular heads are less susceptible to attack by predators, and if predatory attack is targeted to the head of serpents. Artificial snakes were systematically arranged on a road border. The rate of attacked models was 48.71%. Number of attacks on models with rounded head was significantly higher than in models with triangular head. There was a significant difference between the places of attack on the snakes in relation to different head shapes. Therefore, snakes that have head triangulation may be a less frequent target of attacks by predators than those without such behavior.
