A Systems Science Approach to Structure Human Capital Management in Mexican Lodging SMEs
by Juan E. Nunez-Rios, J. Yvette Sánchez-García, Ricardo Tejeida-Padilla, Manuel Soto-Perez
Abstract: This work addresses the process of human capital management in Mexican tourism SMEs. This process affects operations given its limited capability to respond to changes in the environment and binding activities congruently with the coordination and management components. This paper adopted the Systemic Method, addressed through the Soft Systems Methodology to conduct a diagnosis and propose a conceptual model to outline a solution. The relevant systems of this construct were operationalized and contrasted with the Analytical Hierarchy Process. The results show 90% consistency; this indicates that the model reliably represents the reality in which SMEs under study operate and proposed interrelations are acceptable to foster equilibrium. The implications of adopting a systemic perspective require reflecting on the processes of people management, as well as transit from a functionalist approach to an integral one.

Dynamical Interaction of Supervisor-Student towards Research
by Nita Shah, Foram Thakkar, Moksha Satia
Abstract: Research is the step to describe explain, predict and control the observed phenomenon in a systematic way. Researcher have provided a direction to the scientific knowledge for contributing to the development of specialty. In this paper, we will analyze mathematically how the students and supervisor initiate and reach up to their designation which is their destination by carrying out research in collaboration with each other. Using Routh Hurwitz criteria both the equilibrium points has proved to be locally and globally asymptotically stable by the use of Lyapunov function. Bifurcation of the model has been done with respect to the basic reproduction number. Numerical Simulation has been carried out to study various results and impact of the compartments.
Keywords: Dynamical system; Research-Supervisor-Student interaction; Basic reproduction number; Bifurcation.

by Raja Glaa, Mohamed Najeh Lakhoua, Lilia El Amraoui
Abstract: The technological advances, industrialization and the need for modern comfort make the use of electricity necessary and urgent. This allows researchers and engineers to find solutions to the challenges of electricity, integrate renewable energies, increase control and supervision. This paper presents in a first part, the photovoltaic energy production chain as well as the wind production energy chain. In a second part, it presents the need of Objectives Oriented Project Planning (OOPP) method for systemic analysis and modelling. Then, we present the activities matrix based on the systems modelling with the OOPP method in order to analysis the general objectives identified: analysis of the photovoltaic production energy, analysis of the wind farm and finally analysis of the advanced control strategies.
Keywords: renewable energy production; photovoltaic systems; wind power systems; advanced control and supervision; systemic analysis; OOPP method.
A hybrid GA-based RS-RES model for web-multimedia data management to identify determinants of credit rating status
by You-Shyang Chen
Abstract: Web-scale and distributed multimedia data management is urgently needed to address practical problems for real-life applications that will benefit large-scale data sets and resources. The development of an indicator for the operating sufficiency and financial status of Asian banks will be really necessary to better understand the stability of financial markets from managing distributed large-scale data. This study proposes an effective hybrid model with two stages. The stages for the proposed model are described as follows: 1) it organizes random forests and key reducts; and the core of rough-set (RS) rule exploration system (RS-RES) with a genetic algorithm (GA) setting for the benefit of feature-selection techniques to demonstrate various combinations of extracted key features; and 2) the use of the RS-decisional LEM2 algorithm as effective evaluation approaches for measuring various model combinations. To make further verification, a real data set was practically collected from the web-multimedia data from the called BANK-CREDIT database. The target data set contains of 1,327 samples from Asian banks for credit ratings from 19932007. Our research results indicate that the model proposed in this study has a more outperformance than listing models for the standard of accuracy and standard deviation, which indicates clearly model superiority and suitability.
Keywords: web-multimedia data management; credit ratings; feature-selection approach; rough-set technique.
System sequence of surface mining operation
by Padma Charan Mishra, Manoj Kumar Mohanty
Abstract: The magnificent mining super cycle from 2002 to 2010 is gone. Presently the mining industry is struggling with productivity challenges. To understand the complete business and its sequence of process, this study specifically aims at exploring the main operational activities and sub-activities of surface mining industry. Surface mining systems are different for different type of deposits. The paper is concern for forming a sequential model of surface mining operation system prevalent in India. Four massively deposited surface mines were studied at north-eastern peninsular belt and central belt of India by observation method to arrive at a model of sequence. The system sequence will be helpful for both academic study and business purpose to garner knowledge of the operation system. The sub-activities of each function are reflected in the model sequence that gives a complete idea of the complete system of operation of surface mining.
Keywords: system sequence; surface mining operation; model of sequence.
Emergent Uses, as Rumor Systemic Analysis, of Twitter Messages during Social Crises.
by Gregory Chondrokoukis, Ioannis Drakos
Abstract: The hideous, violent and extreme events, anthropogenic or not, taking place on a global scale, are increasing, creating not only an extensive emotional burden among the affected community's population but also testing the whole state mechanism that is in charge to inform citizens. However, in the past there were many cases that the efforts of the official bodies for informing, for varying reasons, were insufficient, so the citizens felt that they did not receive the information they desired and consequently felt helpless in front of the uncertainty. Countermeasure of incomplete information in situations of social crisis seems to be the development of an informal collective communication among the members of the afflicted area, in order to reduce the collective emotional burden through the dissemination of useful information. This information, considering the rapid growth of ICTs, is mostly driven electronically, thus making blogging platforms, and more specifically Twitter, which is quite popular in general public, dominant rather than ever. On the contrary, there are opinions that argue that the credibility of the propagation of this social intelligence is being questioned or degenerated as a rumor. rnThis reason sparked the existence of this work, which aims to study, based on the rumor theory model, the way that users of one of the most popular Social Media tool as Twitter is to take action, to fill their informational gap created in uncertain situations, through the collection, processing and publication of information, taking into account the two social crises that shook public opinion: the killing of Cleveland in 2017 and the bombing attacks on the Coptic churches in Alexandria in 2017.

INFORMATION SYSTEMS FOR THE SOCIAL ADMINISTRATION USING THE SOFT SYSTEMS METHODOLOGY
by Dimitrios Stamoulis
Abstract: Although information systems are very important for the functioning of social administration and the services provision to citizens, they have received little attention both in the research literature and in real-world implementations. Their complex nature due to the various stakeholders and the variety of different social services they have to deliver, calls for a holistic approach in their design, which qualifies the Soft Systems Methodology as the appropriate tool for delivering such systems. To support this argument and pave the way for on-line integrated information systems in social administration, this paper shows how to apply the first four steps of SSM onto a general social administration context, and proposes a conceptual model of an information system in the areas childcare services as an example.
Keywords: social administration information systems; social services information systems; soft systems thinking; childcare services information system.

by Ping Jiang
Abstract: In order to realize ground clearance and leveling control of plant protection machine in high ground clearance. In this paper, a chassis automatic leveling control system is designed. Position error control method and angle error control method are used to control the chassis automatic leveling control system, which is divided into ground clearance height adjustment and chassis leveling control strategy respectively. The system is controlled by combining fuzzy control algorithm and preset point leveling method. The experiment was carried out on the chassis of our self-developed multi-functional plant protection machine with high ground clearance. The results show that the automatic leveling system can complete the chassis leveling well. Its average horizontal error is < 0.20
