Determinants of outward FDI from emerging economies
Authors: Cieślik Andrzej , Hien Tran Giang 
Published: July 2019

Research background: The last four decades have witnessed an upsurge of multi-nationals from emerging markets alongside a narrowed gap in growth prospects between developed and emerging economies. UNCTAD statistics show that FDI flows from emerging economies have gone steady since 1980 and occupied more than one fifth of global FDI stock in 2015. Japan led the reverse FDI trend when it started to invest abroad in the 1960s and 1970s. Two decades later, in the 1980s-1990s, the reverse FDI trend was continued by so-called Asian tigers, then recently by those rapidly-industrializing economies in Southeast Asia as well as China and India in East and South Asia.
Purpose of the article: The main goal of this paper is to contribute empirically to the study of the determinants of FDI outflows from emerging economies.
Methods: In order to derive empirically testable hypotheses this paper refers to theoretical Knowledge-Capital model developed by Markusen (2002). The model is estimated using the Poisson-Pseudo Maximum Likelihood estimation technique. The specific research hypotheses derived from the theory are verified using a panel dataset of 38 home emerging countries and 134 host countries over the period 2001?2012.
Findings & Value added: In this paper, we distinguish between horizontal and vertical reasons for FDI. Our estimation results support the hypothesis that main-stream theory of multinational enterprise can explain FDI flows from emerging economies, implying the significant roles of total market size, skilled-labor abundance, investment cost, trade cost as well as geographical distance between two countries.

Multilayered Autoscaling Performance Evaluation: Can Virtual Machines and Containers Co–Scale?
Authors: Podolskiy Vladimir , Jindal Anshul , Gerndt Michael 
Published: July 2019

Abstract
The wide adoption of cloud computing by businesses is due to several reasons, among which the elasticity of the cloud virtual infrastructure is the definite leader. Container technology allows increasing the flexibility of an application by adding another layer of virtualization. The containers can be dynamically created and terminated, and also moved from one host to another. A company can achieve a significant cost reduction and increase the manageability of its applications by allowing the running of containerized microservice applications in the cloud. Scaling for such solutions is conducted on both the virtual infrastructure layer and the container layer. Scaling on both layers needs to be synchronized so that, for example, the virtual machine is not terminated with containers still running on it. The synchronization between layers is enabled by multilayered cooperative scaling, implying that the autoscaling solution of the virtual infrastructure layers is aware of the decisions of the autoscaling solution on the container layer and vice versa. In this paper, we introduce the notion of cooperative multilayered scaling and the performance of multilayered autoscaling solutions evaluated using the approach implemented in ScaleX (previously known as Autoscaling Performance Measurement Tool, APMT). We provide the results of the experimental evaluation of multilayered autoscaling performance for the combination of virtual infrastructure autoscaling of AWS, Microsoft Azure and Google Compute Engine with pods horizontal autoscaling of Kubernetes by using ScaleX with four distinct load patterns. We also discuss the effect of the Docker container image size and its pulling policy on the scaling performance.
An Active Exploration Method for Data Efficient Reinforcement Learning

Published: July 2019

Abstract
Reinforcement learning (RL) constitutes an effective method of controlling dynamic systems without prior knowledge. One of the most important and difficult problems in RL is the improvement of data efficiency. Probabilistic inference for learning control (PILCO) is a state-of-the-art data-efficient framework that uses a Gaussian process to model dynamic systems. However, it only focuses on optimizing cumulative rewards and does not consider the accuracy of a dynamic model, which is an important factor for controller learning. To further improve the data efficiency of PILCO, we propose its active exploration version (AEPILCO) that utilizes information entropy to describe samples. In the policy evaluation stage, we incorporate an information entropy criterion into long-term sample prediction. Through the informative policy evaluation function, our algorithm obtains informative policy parameters in the policy improvement stage. Using the policy parameters in the actual execution produces an informative sample set; this is helpful in learning an accurate dynamic model. Thus, the AEPILCO algorithm improves data efficiency by learning an accurate dynamic model by actively selecting informative samples based on the information entropy criterion. We demonstrate the validity and efficiency of the proposed algorithm for several challenging controller problems involving a cart pole, a pendubot, a double pendulum, and a cart double pendulum. The AEPILCO algorithm can learn a controller using fewer trials compared to PILCO. This is verified through theoretical analysis and experimental results.

Published: July 2019

Abstract
Indian real estate segment has been one of the utmost affected segments of economy contemplating the changes in economic policies. The Indian economy experienced a radical change as an outcome of demonetization and the consequences are perceived on the real estate segment. The current study has been proposed to evaluate the efficiency of Indian real estate firms by adopting the technique of data envelopment analysis during the pre- and post-period of demonetization. The aim of the research is to understand the effect of demonetization on the performance of the Indian real estate firms during the post-demonetization period compared to pre-demonetization period. Eight real estate firms have been considered for the analysis. The firms have been ranked on the basis of the efficiency score. It is evident from the results of the study that there is a significant difference between the ranks of the firms during the period of pre and post demonetization; and it can be elucidated that the demonetization has an impact on the performance of the firms.
Long-term species richness-abundance dynamics in relation to species departures and arrivals in wintering urban bird assemblages
Authors: Suhonen Jukka , Jokimäki Jukka 
Published: July 2019

Abstract
Temporal dynamics of local assemblages depend on the species richness and the total abundance of individuals as well as local departure and arrival rates of species. We used urban bird survey data collected from the same 31 study plots and methods during three winters (1991–1992; 1999–2000 and 2009–2010) to analyze the temporal relationship between bird species richness and total number of individuals (abundance). We also evaluated local departures and arrivals of species in each assemblage. In total, 13,812 individuals of 35 species were detected. The temporal variation in bird species richness followed the variation in the total number of individuals. The numbers of local departure and arrival events were similar. Also, the mean number of individuals of the recently arrived species (8.6) was almost the same as the mean number of individuals of the departed species (8.2). Risk of species departure was inversely related to number of individuals. Local species richness increased by one species when the total abundance of individuals increased by around 125 individuals and vice versa. Our results highlight the important role of local population departures and arrivals in determining the local species richness-abundance dynamics in human-dominated landscapes. Local species richness patterns depend on the total number of individuals as well as both the departure-arrival dynamics of individual species as well as the dynamics of all the species together. Our results support the more individuals hypothesis, which suggests that individual-rich assemblages have more species.

Published: July 2019

Abstract
The paper is focused on specific location-allocation problem aimed to determine a set of scrap yards for vehicle decommissioning in Slovakia. The goal is to determine scrap yards network so that it is not prohibitive to pass old car for dismantling and further processing wherever former owner lives. Two approaches are considered. Once we consider the case when it is necessary to construct a completely new network of scrap yards, which results to setting of their minimum numbers and also their location. In the latter case, the already existing network of scrap yards is considered, while the model provides its extension, in order to achieve the desired values of accessibility for all residents. The results were applied to an existing network of scrap yards identifying locations to build new scrap yards. Areas where whole new network of scrap yards must be built were also identified.

Published: July 2019

Abstract
The optimal procurement is achieved by monitoring them from the very beginning of the planning process. Procurement planning, as one of the basic functions of procurement management, determines the goals, tasks and the way of their realization. The realization of procurement plans is realized through the purchase function of business entities, both from the domestic and foreign markets.
The specifics of procurement of agro-industrial complex require continuity as a basic requirement. The importance of procurement consists in the fact that the level of reproductive capacity of the agro-industrial complex depends significantly on the normative organization, organization and quality of procurement. The goal of procurement is precisely, timely, quality and under the most favorable conditions, the acquisition of funds on the market, in order to meet the needs for the continuous operation of the companies from the agro-industrial complex.
Accommodation Versus Control Suggested Model to Macro-Economics
Authors: Eltahir Yassin 
Published: July 2019

Abstract
The study raised the question of knowledge generation, in attempt to answer this question an economic model was introduced, namely, aggregate demand and aggregate supply. The final target equations can be solved by general rule (deterministic) of solving quadratic equations. The study use analytical geometry and matrix algebra tools to solve the model beside testing their stability characteristics. If we reach unique value to the price equilibrium level then income equilibrium level the maximum potency of the economy can determined. Accordingly the rest of model values would be solved spontaneously. The essential derived result is the relationship between the dependent variable and independent variable can be redefined into accommodated and accommodator one. The long run growth rate of price and income which equal to the equilibrium combat with exogenous theory of growth which seeking stable and sustainable growth. Other results center around how to view the debate of different economic schools from the shape of aggregate demand and aggregate supply, moreover the theoretical and practical test of model give great push to the suggested approach in answering the questions raised concerning the knowledge generation. If the model succeed in exceeding the theoretical and practical tests our understanding to the phenomena functioning will be broaden and enhanced, hence the model capability can be enlarged to interpret phenomena in fields other than economic, typically the suggested approach “top to bottom” may contribute positively to the process of knowledge generation in addition to the modification of value system extraction. Finally the study suggested a protocol scenario in how to apply the derived model by introducing different steps to the application.
Laryngeal Relativism predicts Italian
Authors: Berces Katalin Balogne , Huszthy Balint 
Published: July 2019

AbstractTwo-way laryngeal systems are classified by Laryngeal Realism into [voice] languages (or “L-systems”, e.g., Slavic, Romance) and [spread glottis] ([sg]; or aspiration) languages (or “H-systems”, e.g., the typical Germanic pattern). More recently, Cyran (2014) has proposed Laryngeal Relativism (LR), claiming that phonetic interpretation is arbitrary, and as a result, two phonetically identical systems, even two dialects of a language, may turn out to diverge phonologically. His example is Polish: while Warsaw Polish represents the typical [voice]/L-system, he analyses phonetically identical Cracow Polish as anH-system (counter to Laryngeal Realism’s uniform classification of Slavic languages).However, in the “classical” version of [sg] languages (e.g., English), no laryngeal activity in the form of any kind of spreading is attested, which suggests the absence of any source element and, instead, a dominant role of obstruency (|h|). We, therefore, arrive at a three-way typology:h-systems,H-systems andL-systems. At the same time, arbitrary phonetic interpretation in LR predicts the existence of, e.g.,h-systems with virtually no aspiration in the fortis series. We claim that this is indeed the characterisation of Italian. Using data from potential feature spreading situations, elicited in loanword and foreign accent settings, we show that Italian is anh-system, exhibiting no true laryngeal activity.
