Demand deficiency, money velocity and heterogeneity
Authors: Basci Sidika , Gherbi Tahar 
Published: June 2020

Aim: Money velocity data for the United States show that there is a decline in all of the broad money aggregates in recent decades. This points to a sustained demand deficiency element. Can consumer heterogeneity be the cause of this declining trend? The aim of this paper is to find an answer for this question.

Design / Research Methods: To achieve our aim we use Agent Based Modelling (ABM). In our model, the agents are heterogeneous consumers with different spending propensities.

Conclusions / findings: We show that heterogeneous consumers with different spending propensities alone puts a downward pressure on money velocity. This pressure is coupled with a sustained worsening in the wealth distribution. We observe that as money accumulates in the hands of agents with the lowest propensity to spend, money velocity keeps declining. This also puts a downward pressure on nominal aggregate demand and hence a deflationary bias on the general price level.

Originality / value of the article: This paper shows that heterogeneity of economic agents should not be ignored and that ABM is a very powerful tool to analyse heterogeneity.

Implications of the research: The implication for policy makers is that the demand deficiency associated with the fall in money velocity will persist until the worsening of wealth dispersion comes to a halt.
Effects of Terrorism and Political Instability on Tourist Behavior: 2016 conflicts in Turkey
Authors: Koyuncu Onur 
Published: June 2020

Aim: This article investigates the effects of two attacks and a failed coup attempt during 2016 on the tourist behavior. Foreign tourist data for the 2003-2019 period is analyzed to observe irregularities in Turkey’s national tourism income.
Design / Research methods: Linear regression, multivariate regression and regression based static forecasting methods are applied for modeling the relationships. These models are supported with statistical tests.
Conclusions / findings: Results on this study are in accordance with the current literature in the sense that conflicts in 2016 caused a shift in tourist behavior which in turn impaired the tourism industry in Turkey. Repercussions did not endure longer than expected and Turkish tourism recovered rapidly, only facing a serious loss due to the shift in tourism demand trend.
Originality / value of the article: This study makes an addition to the terror and tourism literature, especially for the Mediterranean region and specifically for Turkey both of which are among the most popular tourist destinations worldwide. The aftermath of attacks and the coup attempt in Turkey during 2016 have not been researched before. The data and the outcomes presented sufficient evidence to infer on this issue.
Stock Market Reactions to Financing and Payment Decisions for European Mergers and Acquisitions
Authors: Bessler Wolfgang , Kruizenga David , Westerman Wim 
Published: June 2020

Aim: We analyze stock market reactions to merger and acquisition announcements for firms in Europe and contribute to the literature by providing empirical evidence how the decisions with respect to alternative financing sources (equity or debt) and the methods of payment (cash or stock) affect the magnitude of the valuation effects.

Research design: An event study methodology is applied to 717 M&A transactions. We analyze the size of the cumulative abnormal returns using the financing sources and payment methods and other variables as the relevant determinants.

Findings: The cumulative abnormal results suggest that target shareholders and bidder shareholders in private deals benefit from mergers and acquisitions. The effect found is centered around the announcement date, making our findings consistent with market efficiency. Debt financed deals outperform equity financed deals and cash paid M&A outperform stock paid M&As, due to information asymmetry, signaling and agency effects.

Originality: This study adds to our understanding of the relevance of the financing sources and the payment methods for mergers and acquisitions in Europe.

Implications: This study may help practitioners to better assess the valuation effects of alternative financing sources and payment methods when acquiring other firms.

Cash management organisation decision-making: economics, strategy and operations
Authors: Westerman Wim 
Published: June 2020

Abstract:

Aim: This article starts from the observations of two cash management experts, who witness varying company views on the almost-vanished issue of structuring the internal decision-making on the organisation of it. The aim of this article is to put the current challenging developments in a digitalizing world into a conceptual perspective.

Research design: The article singles out motives for either centralization or decentralization of cash management, models to organize cash management functions, as well as developments in the field over the last some thirty years. Various theoretical views are studied briefly in order to find a way out of the signalled paradox.

Findings: It can be concluded that multiple practices may coexist both within and between firms, whereby a refined understanding in terms of financial economics, strategic direction and operational flexibility is called for.

Originality: The present study is unique in that it is among the first to signal the return of the centralisation versus decentralisation issue in cash management in a rapidly evolving digital era and multi-legislation world.

Implications: The developments offer a unique opportunity for firms, further reducing their costs, to overthink their cash management system, including its relation to the external world. The study calls for follow-up research in terms of case studies at organisations with varying contingencies and survey questionnaires among representative samples.

Keywords: cash management organisation, (de-) centralisation, decision-making

Authors: Tuncay Ezgi , Karan Mehmet , Miski Aydin Eren 
Published: June 2020

The study aims to evaluate the initial public offering performance of Borsa Istanbul companies during the hot and cold periods. The size of the companies, industry concentration and investor optimism are considered in this respect. The study covers the 119 IPOs of various sizes from different industries between 2010 and 2017 just after the global financial crisis. The standard event study methodology is applied. This study has revealed the existence of post-crisis underpricing effects in Turkey. Moreover, the research shows that although low pricing is valid in hot periods, hot and cold markets do not differ significantly from each other in this context. Besides, this study finds that the low price effect exists for small firms, and this effect is more common in hot markets. On the other hand, although there is a relationship between consumer confidence index and low price, no relation with industry concentration was found.
KONSEP ETIKA BISNIS ISLAMI DALAM KITAB SAHIH BUKHARI DAN MUSLIM
Authors: Darussalam Andi Zulfikar 
Published: June 2020

This article verifies that hadith of Prophet Muhammad SAW. do not limit someone’s wealth amount (results) from a business activity, but limit how method (process) to acquire (result) of a business activity. It indicates that in business activity, hadis of Prophet Muhammad SAW. put more emphasis in importance of process (business ethics) compared to result, in order that there is none who would do evil deed or there is none who would suffers evil deed.
This article shows that process of a business activity shall be based on business ethics. Business ethics are gathered from guideline from the Prophet Muhammad SAW. emphasized on two important things; firstly, conducting business activity with reasonable business behavior, secondly, avoiding disgraced business behavior. The business ethics have been practiced by Prophet Muhammad SAW. in conducting business activities before his appointment as Prophet.
The main source of this study is texts (the Prophet’s utterance) that contained in (hadis books) Sahih al-Bukhari and Sahih Muslim. Beside of that, in order to make more deeper comprehension on those texts, supporting sources are used such as syarah al-hadith book and fiqh books. In order to read those texts are taken thematically (maudu’iy) and also to be enriched by theories and methodologies from other disciplines such as history.
TO CALCULATION OF ELLIPTIC CRUSHER WITH FORM MEMORY EFFECT
Authors: Shishkin Sergey 
Published: June 2020

The investigation purpose consists in the development of a calculation model of a thermo-mechanical power device intended for destruction of concrete structures and hard mineral rock. Its operation principle is based on the transformation of the initial round cross-section into the oval one during realization of alloy form memory that ensures a wedging effect.
There is offered the solution of the problem on linear effort definition of a crusher at its impact upon well sides depending on rock resistance and capacity of thermo-mechanical return. The investigation method consists in the modeling of a power pipe with the cylindrical shell at its non-axisymmetric loading as a deformation-power analogue of which a thermo-mechanical diagram is accepted. The essential condition of such an approach is the identity of a task and deformation restoration with samples at the diagram formation and a power element in the structure.
Thereupon fundamentally new is a calculation definition of the parameters of reactive stress dependence upon the deformation value of under-restoration at radial bending according to the diagram at the specified deformation by stretching that allows excluding a labor-intensive experiment.
As a result of the investigations there are obtained formulae for the definition of a linear effort and also for the computation of pipe dimensions within the limits of design calculation.
There is shown an actual example of power characteristics definition. The calculation reliability is confirmed with the application of these power devices during radioactive concrete structure destruction at one of nuclear power plants and at hard rock destruction at emerald field development. In such a way, the thermo-mechanical crusher design offered and a corresponding procedure for calculations can be used in practice without any changes.

Authors: Vayner Leonid 
Published: June 2020

The paper is dedicated to the bilateral end-finishing improvement at the expense of efficient kinematic characteristics realization in parts machined ensuring limiting errors minimization in end surfaces.
A systematization of parts rotation experimental characteristics is carried out. It is shown that they may be referred to six basic kinds. There are offered equivalent characteristics of rotation used while grinding modeling and their mathematical description is given. The dependences obtained determine a kinematic parameter of a shaping form in the equation of the surface worked.
There is considered an influence of billet rotation characteristics upon shaping and accuracy of frictionless bearing cylindrical roller machining under virtual technological conditions equivalent to industrial. As a result of computer experiments carried out it is defined that dynamics and balance of shape errors and a relative position of end surfaces of the roller to a considerable extent are defined with the kind of realized rotation characteristics.
The error sensitivity of a shape and end beating to kinematic characteristics realized and technological parameters must be taken into account during bilateral end-finishing control.

The conditions of RZA device operation at different earth methods of contact system masts are under analysis. The analysis of the ways of SC current behavior at different methods of contact system mast grounding is carried out, the factors influencing the scenarios of development and circuit parameters of SC are emphasized.
The investigation object is an operating area of the railway located in the far East of Russia, and investigation subjects are its devices of relay protection of the contact system feeders. There are used methods of a structured observation and statistical analysis of in-situ resistance measurement results of contact system masts and parameters measured with protection, a simulation method of traction power supply system, method of data visualization on a complex plane.
There is carried out a type classification of contact system mast earth, the analysis of short circuit current behavior at different earth types of ac contact system mast is fulfilled, the estimate of the impact degree of transient resistance arising at the moment of short circuit under conditions of remote protection operation is carried out.
The most probable reason of remote protection non-operation in case of short circuit on non-earthed contact system masts is revealed. On the basis of the results obtained in the course of full-scale measurement there is compiled a diagram of a share distribution of contact system masts with the different value of active resistance. It is determined that the overwhelming majority of contact system masts have less 20 kOhm active resistance, but there is marked the presence of contact system masts with a high value of active resistance that is evidence of unintentional un-earth which worsens deeply the operation of relay protection devices. According to the results of the investigations carried out there is offered a method of data visualization on a complex plane on the basis of the results of the modeling of traction power supply system parameters and in-situ measurements which allows approaching in a complex way to the solution of the problem in relay protection device operation stability increase under conditions of heavy-freight motion intensity and volume increase.
SUGGESTIONS ON CORRECTION OF PROCEDURES REGULATING FULFILLMENT OF NOISE METERING AND VIBRATION METERING TESTS OF PASSENGER CARS
Authors: Liferenko Vladimir 
Published: June 2020

The work purpose is the development of suggestions on the improvement of labor conditions for passenger car conductors. In the paper there is shown information on conductor health, diseases connected with the vibration high level impact. On the basis of the experience of CC SA “TIV” for the solution of the problem specified there are introduced suggestions on changes of the standard base regulating the fulfillment of noise metering and vibration metering test.
The expediency of the changes offered is also substantiated with the potential of modern instrument-ware. The absence of the necessity for the definition of vibration indices at a motion speed up to 80 km/h is shown. A possibility to obtain objective data on vibration processes in a car during measures with the 20 km/h intervals is called into question. A regularity connecting the frequencies of dominating vibration with the speed of a car motion is determined. There are given specific recommendations on the adjustment of procedures to obtain reliable information on noise and vibration perceived by passengers and service personnel. It is emphasized that maximum noise levels arise at maximum vibration levels therefore there is drawn a conclusion on the expediency of the synchronization of these tests. On the basis of the material presented in the work the following conclusions are drawn: in the resent years are not observed improvements in conductor morbidity rates connected with the impact of vibration higher levels; on the consequences of vibration impact upon passengers it is possible to judge by a health state of conductors; the introduction of the changes offered will result also in time saving and cost decrease of test fulfillment.

El manejo inadecuado de antimicrobianos (ATM), tiene como consecuencia el aumento de la resistencia de los gérmenes, problema actual en salud pública. El objetivo de este trabajo fue identificar el uso y la prescripción de ATM utilizados en la clínica de animales de compañía, en la ciudad de Córdoba, Argentina. Se realizó un estudio observacional, mediante un cuestionario compuesto por 18 preguntas. El 98% (149/152) de los profesionales encuestados, utilizó ATM en forma empírica, siendo los más empleados penicilina y sus derivados (74%). Frente a síndromes de piel y urinario, se observó una mayor probabilidad estadística de prescripción empírica (2,08 y 3,22 veces respectivamente). Debido a la alta frecuencia observada en el uso de ATM y siendo algunos de ellos clasificados como de importancia crítica en medicina humana, es necesario contar con datos epidemiológicos locales, para orientar los tratamientos empíricos iniciales y crear planes de vigilancia y control para su uso.

Academic skills in the screenish era
Authors: Bradley Peter 
Published: June 2020

Our culture has begun to react to the implications of digital technology for our shared memory and individual privacy in the form of legislation like GDPR. But the culture of higher education---specifically the dominant model of knowledge generation and transmission---stays firmly rooted in the 'bookish' tradition. Honors education was started in response to the changing world in the wake of WWII. Its core principles of engaged learning and individualization of the student experience can lead higher education to embrace the new culture of digital technology-assisted knowledge generation and transmission.
