Can Narrative Economics Justify Economic Fluctuations and Inequality? An Approach from Micro to Macro Perspective

Authors: Monika Gaur, Ravi Kant

ABSTRACT
The opus dwells on aspects of building narrative, especially for state policies. It thoroughly examines economic narratives as a reason for the economic fluctuations and aggrandizement of resources. The present work is a watershed development while explaining the factors behind the foreplay of the economic system, engages upon a bottom-up approach, and provides a model for the impact of narrative-driven choices at the micro and macro levels contemplating the role of narrative in escalating inequality. The present research is intrigued by the fact that narratives form an inextricable role while forming and implementing state policies; moreover, non-developmental narratives can dampen the impact of desired policy and economic objectives. Importantly, since facts do not always back narratives, erratic economic and social outcomes petered out from conventional policy action. A few wealthy and resourceful people can swing the narrative and build upon by the low literacy, learning poverty, lack of rational approach, religious and caste factors. Such narratives subsequently influence people’s decisions, often their political decision, which enhances their probability of acquiring more wealth, leading to a perpetual concentration of wealth and power in few hands. The reason for the “perpetual concentration” of wealth and power lies with the existence of strong narratives that directly or indirectly reinforces aggrandizement and causes penury to the few left out underprivileged sections. Such inequality will be nothing short of being narrative-driven inequality. The research also emphasized the role of institutions, media, and technology, which unanimously plays a crucial role in creating, validating, and disseminating narratives. An overall ethical responsibility must be felt and shared for the common good and shared prosperity. The participative decision making helps dilute non-developmental narratives.

Lagrangian Model PETROMAR-3D to Describe Complex Processes in Marine Oil Spills

Authors: Amilcar E. Calzada, Iván Delgado, Carlos Ramos, Frank Pérez, Dailín Reyes, Dayana Carracedo, Alejandro Rodríguez, Dayron Chang, Javier Cabrales,

ABSTRACT
The version 2.1 of PETROMAR-3D model, created in the Center for Marine Meteorology of the Meteorology Institute of Cuba, is presented. This Lagrangian model has been designed to describe the physical processes of marine oil spills in the face of multiple scenarios of the marine environment. Although it is applicable to any part of the world, it is mainly designed for inter-American seas. The novelty has been to integrate the processes of drift and weathering into a model, with updated methods that incorporate 3D phenomena, a very favorable situation to achieve an operating system in Cuba and the region for the immediate and medium term. Python was chosen as the programming language because it has advanced libraries for numerical modeling, automation work and other useful tools for pre-and post-processing. By means of adapters, an important number of atmospheric, hydrodynamic and wave models have been considered to create the scenarios efficiently. The modular distribution in which the code has been created facilitates its use for other dispersion analysis and biophysical applications. Finally, a set of simple images are presented, aimed at informing decision-makers in order to mitigate the effects of the spill on the environment.

Relationship between Logistics Firm Size and Business Diversification: An Empirical Study of Chongqing, Area in China

Authors: Nannan He, Wanshan Wu, Sijing Liu

ABSTRACT
CThis paper aims to explore the relationship between logistics firm size and business diversification, especially in micro- and small-sized enterprises, and assess the diversification process of Chongqing logistics enterprises using new data source. It is intended to contribute to theoretical research on diversification in the emerging logistics industry based on resource-based view (RBV) and factor production theory. We innovatively establish the logistics business classification system, then measure the degree and direction of diversification of logistics enterprises based on mean narrow-spectrum diversification-based product count methods. The empirically shows that there are a growing number of highly-diversified logistics enterprises in general, with an average annual increase of 14.23%. Especially after 2008, small and medium-sized enterprises developed towards related diversification while micro-sized enterprises came to the opposite conclusion. For them, creating unrelated diversified business is a crucial way to generate a competitive advantage. Unlike the conclusions derived from other industries, small-sized logistics enterprises are prone to try a new business, both related and unrelated, for better survival and performance. And changes in the firm size of medium and large-sized enterprises have little impact on the development of the business diversification.

Ant Species Richness Variation Mediated by Seasonality in Two Ant-Acacias from Oaxaca, Mexico

Authors: Sandra Luz Gómez-Acevedo, Javier Martínez-Toledo

ABSTRACT
Climatic conditions affect the richness of ants resulting in number variation throughout the year. The ants present in the Neotropical system Acacia-Pseudomyrmex have been previously studied considering only one sampling season. In contrast, in this study we analyze the richness in two ant-acacia systems during the rainy and dry seasons. The study was carried out on a plot located in the state of Oaxaca, Mexico where 14 ant species, 3 mutualistic and 11 non-mutualistic were found, of which 2 represent new records for the state. Ant species number differed between ant-acacia species and between seasons. The highest richness was recorded in Acacia hindsii in both rainy and dry seasons, corresponding with a low-reward host. During the dry season, A. hindsii represents a highly valuable resource. This study shows that the neotropical system is much more dynamic than it has been previously considered and offers a valuable opportunity for subsequent ecological studies for a better understanding of this complex system.

Integration of Digital Technologies into Underground Utility Asset Management

Authors: Eronmonsele Esekhaigbe, Emrah Kazan, Mumtaz Usmen

ABSTRACT
Installation, detection, maintenance, mapping, and management of underground utility assets present challenges to owners, engineers and contractors. Industry-wide practices include the use of geophysical and similar technologies to determine depth and location, and 2D as-built plans integrated with GIS databases for information management. The feasibility of incorporating 3D BIM models of the subsurface to replace the 2D plans to improve visualization and data management is examined in this paper. Obtaining an accurate image of the underground infrastructure would help minimize excavation accidents due to equipment-utility collisions and prevent property damage. Further, the inclusion of automated data collection and sharing features realized through BIM technology can enhance operations of smart cities. The research methodology consists of a state-of-the-art review of the current underground utility management systems, combined with statistical analysis of survey responses received from utility providers and one-call centers in the U.S. Three categories of utility practices are identified based on the level of digital technology integration. It is found that a vast majority of utility firms have adopted GIS databases with 2D plans, depth and other asset information, while a smaller percentage of providers have achieved full GIS-BIM integration, incorporating a wide range of asset data. Future progress on broader implementation appears to be constrained by the digital literacy of personnel and high costs of technology acquisition and application. A three-step framework for converting 2D plans to 3D BIM models is also presented and discussed. The process model proposed for this purpose allows the utilization of commercially available software with minimal need for additional coding.

Modified Vanstone’s Construction of lightweight MAC for Vehicular On-Board IT Systems

Author: István Vajda

ABSTRACT
We propose a lightweight construction, a modification of Vanstone’s MAC construction, for the message authentication of the communication between Electronic Control Units (ECUs) in distributed car control systems. The proposed approach can solve the task of error control and authentication in unified algorithmic technology, called MAC (Message Authentication Code) with ECC (Error Correction Code). We follow a provable approach in the design of the cryptographic primitive, where we quantify the security measures in the parameters of the system. Provable security approaches are missing in the field of secure in-vehicle communication.

Formation of Diffusion Pairs as an Initial Stage in the Process of Decomposition of Alloys

Author: Yuri Ustinovshikov

ABSTRACT
The paper discusses the researches that formed the basis of the study of the transition of “ordering-phase separation” and the reasons for such transition occurrence. Experimental results have presented what diffusion pairs are and how they occur in binary and multicomponent alloys. The paper illustrates that the chemical bonds between atoms are realized on the principle of pair interaction in both solid and liquid states of the alloy. The process of separating a multi-component ABC alloy into diffusion pairs A/B, A/C, and B/C occurs in a liquid solution, where the diffusion mobility of atoms is very high, and the resistance of the environment is relatively low. The driving force of such a process is the chemical attraction between like and unlike atoms, that is, the tendency to phase separation and the tendency to ordering. Quenching the liquid alloy into the water fixes a microstructure consisting of microscopic areas corresponding in composition to one or another diffusion pairs. The paper shows what exactly should be done so that such a branch of science as Materials Science could get rid of the empirical approach when creating new alloys.

Occupational Burnout: A Comparison of Field Research of General and Psychiatric Hospitals in Greece after the Financial Crisis

Authors: Aspasia Goula, Georgia Koufioti, Athanasios Kounios, Anastasios Sepetis

ABSTRACT
At a time when rates, employment demands, insecurity and stress are on the rapidly increasing, exhaustion and stress are becoming an everyday reality for more and more professionals, with detrimental effects on their health, family and professional relationships. The aim of the study is to evaluate statistically significant differences of professionals between general and mental health hospitals. A questionnaire survey was carried out on 128 employees in general health units and 99 employees in mental health units, in Athens, Greece. The results showed statistically significant differences in the variable of personal achievement to a significant level. Employees in mental health units provide a higher average value for this variable than employees in general hospitals. The variable of personal achievement demonstrated statistically significant differences between employees of different age groups, marital status and educational level. Older employees, married employees and lower-level educated employees have been identified to have a higher mean value as a variable of personal achievement. Statistically significant differences were observed in relation to emotional exhaustion factor among employees of different specializations. Nurses, and subsequently physicians, report higher mean values for emotional exhaustion than managers and paramedical employees who report lower mean values for this variable. Enhancing awareness of the phenomenon of occupational burn-out can lead to development of effective intervention measures aimed at improving the well-being of medical and nursing staff, assuring the best possible outcome with the least possible medical risk and optimizing maximum possible health risk of patients.

Manifestation of Color Confinement in the YY Model for Atomic Nuclei

Authors: Hongguang Yang, Weidong Yang

ABSTRACT
In this paper, a manifestation of the well-known color confinement from the QCD (quantum chromodynamics) in the newly developed YY model for the atomic nucleus is presented. There is a wonderful correspondence between the structural requirements from the YY model and some elementary properties of the color dynamics from QCD. The open questions in the YY model, namely the holding forces for triple nodes and for pairing space links, are exactly covered by the three-color compensation or by the paired color anti-color balance. We will see what colors and anti-colors do mean in the YY model, how up quarks and down quarks get assigned a color or anti-color. We will discover some relationships between gluon-based interactions as described in the standard model and pairing space links in the YY model.

A Bioelectromagnetic Proposal Approaching the Complex Challenges of COVID-19

Author: Andras Szasz

ABSTRACT
The COVID-19 pandemic has experienced unprecedented limitations and extraordinary scientific efforts to address this exceptional situation. Despite blanket closures that have resulted in significant financial constraints and losses around the world, research has an “unlimited” budget, with an exceptional concentration of medical and scientific care on a single topic: understanding the mechanisms for overcoming the disease. A large number of clinical trials have been launched with different drugs that have been behind different concepts and solutions. I would like to focus on the complexity aspect of COVID-19. Living systems are organized in a complex way, which implies dynamic stochastic phenomena, and deterministic reductionism can mislead research. When research focuses on individual molecules or pathways as products, it is distracted from the processes in which these products operate, thus neglecting the complex interactions between regulations and feedback controls. Common problems in product-oriented research are articulated as “double-edged swords”, “Janus behavior”, “two-sided action”, with a simple question: “friend or foe?” I focus on the missing complexity. I propose a bioelectromagnetic process that can maintain a complex approach, affecting processes rather than products. This hypothetical proposal is not a comprehensive solution. Complexity itself limits the overall effects of causing “miracles”. Well-designed electromagnetic effects can support current efforts and, in combination with intensively developed pharmaceuticals, bring us closer to a pharmaceutical solution against COVID-19.
