Abstract

Purpose

People who suffer from phobias try to avoid a specific object or feared situation by creating a great obstacle that causes serious consequences in their daily life; the most effective way to deal with a phobia is through exposure therapy, which according to one of the most important principles of psychology states that to overcome a fear you have to face it. The purpose of this paper is to develop a mobile application based on augmented reality (AR) for the treatment of spider phobia (Araneae).

Design/methodology/approach

The application development methodology was divided into two phases: design where sketches were made according to functional requirements, and the client server model was used for user queries and the development phase where the modules for the information of the phobia; and visualization of the arachnid in different morphological forms was implemented through the development tools.

Findings

The findings of this study, in this sense, state that it was possible to overcome the phobia in an essential way by ceasing to perceive harmless things as dangerous, helping them to manage stress and keep them under control.

Originality/value

Allowing to face their fears in support of existing therapeutic processes through images with progressively AR, being an innovative and accessible treatment from an economic, technological and professional point of view.

Abstract

Purpose

The purpose of this paper is to address the case of toxic metal contamination of Sepetiba Bay caused by the Ingá Company. The paper reviews the history of the contamination and discusses the current presence of metals in the bay sediments, demonstrating that the toxic metals are clearly enriched. Sepetiba Bay is prone to significant dredging activities that make metals available in the food chain, affecting human populations, mainly fishermen communities.

Design/methodology/approach

The study presents the case of the Ingá Company based on international literature and data provided by previous studies.

Findings

Through the analysis and compilation of diverse data from the literature, this study demonstrates that the Ingá Company is a major source of Cd, Pb and Zn due to its calamine processing activities used to obtain high purity Zn.

Originality/value

This study highlights important research to complete the historical scenario of heavy metal contamination of the Sepetiba Bay by Ingá Company. The results indicate that the contaminants from the Ingá Company can indeed be traced in the sediments of Sepetiba Bay. These data have the utmost value for the environmental management of this coastal system, because such high concentrations of toxic metals in marine sediments have serious implications for the environmental quality of the bay and may negatively affect biota and human health. Therefore, this study suggests that it is now necessary to monitor this region for contamination continuously.

Abstract

Purpose

The purpose of this paper is to evaluate Chinese indirect trade relations in the global trade network to observe if the objectives identified by Cai (2017) in the Belt and Road Initiative (BRI) are being fulfilled, especially with Latin America and the Caribbean (LAC) countries.

Design/methodology/approach

Using data from the UNCTAD (2016) for the period 2011–2015, a normalized exports network is built. It is analyzed with the Forgotten Effects Theory and the PageRank algorithm. A Monte Carlo experiment with 10,000 replicates is performed to account for its volatility.

Findings

The paper identifies one instance in which China's peripheral countries are importing raw materials and commodities -–oil products – to produce low technological value-added products, which, in turn, are exported to China. LAC countries do not have significant indirect trade relations with China when the former is the origin country, while the latter is the destination in a trade relationship. The trade network has a clear core-periphery structure, with China belonging to its core, although being only the fourth most central node in the network.

Originality/value

This paper contributes with both a new methodology for the analysis of indirect trade relations and the results found for China under the BRI and its trade relationship with LAC economies.

Abstract

Purpose

This paper aims to identify key sectors in carbon footprint responsibility, an introduced concept depicting CO2 responsibilities allocated through the supply chain containing sectoral activities and interactions. In detail, various key sectors could be identified according to comparative advantages in trade, sectoral linkage and sectoral synergy within the supply chain.

Design/methodology/approach

A semi-closed input–output model is used to make the household income–expenditure relationship endogenous through the supply chain where sectoral CO2 emissions are calculated, and the production-based responsibility (PR) principle is evaluated. Thus, according to “carbon footprint responsibility”, modified hypothetical extraction method is applied to decompose sectoral CO2 in terms of comparative advantages in trade, sectoral linkage and synergy. Finally, key sectors are identified via sectoral shares and associated decompositions in carbon footprint responsibility.

Findings

Compared to 2005, in 2012, the PR principle failed to track sectoral CO2 flow, and embodied CO2 in import and interprovincial export increased, with manufacturing contributing the most; manufacturing should take more carbon responsibilities in the internal linkage, and tertiary sectors in the net forward and backward linkage, with sectors enjoying low carbonization in the mixed linkage; inward net CO2 flows of manufacturing and service sectors were more complicated than their outward ones in terms of involved sectors and economic drivers; and residential effects on CO2 emissions of traditional sectors increased, urban effects remained larger than rural ones and manufacturing and tertiary sectors received the largest residential effects.

Originality/value

The value of this paper is as follows: the household income–expenditure relationship got endogenous in intermediate supply and demand, corresponding to the rapid urbanization in megacities; key sectors were observed to change flexibly according to real sectoral activities and interaction; and the evaluation of the PR principle was completed ahead of using a certain CO2 accounting principle at the city level.

Abstract

Purpose

The purpose of this paper is to validate and apply enrichment diagrams (EDs) to determine metal and as enrichment and contamination in the sediments of Sepetiba Bay.

Design/methodology/approach

Through inducted coupled plasma – optical emission spectrophotometry, total element (As, Cd, Cu, Ni, Pb and Zn) concentrations were assessed for the construction of EDs and comparison with enrichment factors (EFs) in 65 samples collected in Sepetiba Bay.

Findings

Based on the EDs, it was observed that the sediments around the urban area of Sepetiba and ItaguaíHarbor were contaminated with Cd, Cu, Ni, Pb and Zn. These contaminants were expected due to the urban and industrial discharges into the bay and the activities at ItaguaíHarbor.

Originality/value

The ED was successful regarding its ability to evaluate inorganic contamination in Sepetiba Bay. In addition, this method was able to define a proper background sample for calculating EFs.

Abstract

Purpose

Displacement measurement in large-scale structures (such as excavation walls) is one of the most important applications of close-range photogrammetry, in which achieving high precision requires extracting and accurately matching local features from convergent images. The purpose of this study is to introduce a new multi-image pointing (MIP) algorithm is introduced based on the characteristics of the geometric model generated from the initial matching. This self-adaptive algorithm is used to correct and improve the accuracy of the extracted positions from local features in the convergent images.

Design/methodology/approach

In this paper, the new MIP algorithm based on the geometric characteristics of the model generated from the initial matching was introduced, which in a self-adaptive way corrected the extracted image coordinates. The unique characteristics of this proposed algorithm were that the position correction was accomplished with the help of continuous interaction between the 3D model coordinates and the image coordinates and that it had the least dependency on the geometric and radiometric nature of the images. After the initial feature extraction and implementation of the MIP algorithm, the image coordinates were ready for use in the displacement measurement process. The combined photogrammetry displacement adjustment (CPDA) algorithm was used for displacement measurement between two epochs. Micro-geodesy, target-based photogrammetry and the proposed MIP methods were used in a displacement measurement project for an excavation wall in the Velenjak area in Tehran, Iran, to evaluate the proposed algorithm performance. According to the results, the measurement accuracy of the point geo-coordinates of 8 mm and the displacement accuracy of 13 mm could be achieved using the MIP algorithm. In addition to the micro-geodesy method, the accuracy of the results was matched by the cracks created behind the project’s wall. Given the maximum allowable displacement limit of 4 cm in this project, the use of the MIP algorithm produced the required accuracy to determine the critical displacement in the project.

Findings

Evaluation of the results demonstrated that the accuracy of 8 mm in determining the position of the points on the feature and the accuracy of 13 mm in the displacement measurement of the excavation walls could be achieved using precise positioning of local features on images using the MIP algorithm.The proposed algorithm can be used in all applications that need to achieve high accuracy in determining the 3D coordinates of local features in close-range photogrammetry.

Originality/value

Some advantages of the proposed MIP photogrammetry algorithm, including the ease of obtaining observations and using local features on the structure in the images rather than installing the artificial targets, make it possible to effectively replace micro-geodesy and instrumentation methods. In addition, the proposed MIP method is superior to the target-based photogrammetric method because it does not need artificial target installation and protection. Moreover, in each photogrammetric application that needs to determine the exact point coordinates on the feature, the proposed algorithm can be very effective in providing the possibility to achieve the required accuracy according to the desired objectives.

Abstract

Purpose

The purpose of this paper is to verify existence of political connection of firms in India. For this purpose the paper first presents a theoretical model and then tests empirically the movement of stock prices during two state elections in India.

Design/methodology/approach

The methodology is theoretical modelling where the paper applies the standard Cournot model of oligopoly. The paper then applies correlation and Wilcoxon Paired Rank Sum test to verify the results of the theoretical model by using data from the Indian stock market during the election results.

Findings

The theoretical result states that some firms opt for political connection and some remain independent in an oligopoly. It also shows that political connection affects stock price. The empirical results find out that divergent responses of stock prices to the election results can be linked to politically connection.

Research limitations/implications

The theoretical model is a simple two firm model and not generalized to n number of firms. The empirical test considers only two state elections and applies simple statistical test. The study is restricted to one country only.

Practical implications

The paper has practical implications for stock market. It has implications for corporate governance and for political governance. This is important since political connection of firms has emerged as an important issue in India.

Social implications

The paper is important as it addresses the issue of political connection of firms, which have ramifications for social equilibrium. In a democratic country like India any nexus between political party and firms may adversely affect not only corporate governance but also political governance.

Originality/value

This paper looks at political connectedness theoretically in a federal structure, an issue not addressed so far in the literature. Second it considers not so discussed topic of market perception of political connection in India. The originality of the paper is that it presents a theory and also verifies the theoretical results with empirical test.

Abstract

This column has always intended to provide in‐depth, comparative reviews of abstracting services, indexes, serial bibliographies, yearbooks, directories, almanacs and other serial tools which would normally be housed in reference departments. For the purposes of this column, reference serials are materials which must meet two rather flexible requirements: they must be useful as reference sources and they must be issued as serials or be titles which are superseded periodically by new editions.

Abstract

Purpose

The aim of this paper is to analyze relationships of cooperation and conflict between a mining company and the involved communities, focusing on the presence of the mining company (MSX) in Cerro de San Pedro, Mexico.

Design/methodology/approach

The paper focuses on the co‐operation and conflict between firms, communities, new social movements and the role of government.

Findings

The presence of the mining company has caused a severe social conflict among the inhabitants of San Pedro, Soledad y San Luis, alerting all who are concerned with historic heritage, cultural and environmental issues. At the center of the controversy is the cheap and efficient technology. Federal and state laws were violated. It is quite evident that there was a lack of sensitivity of foreign mining companies toward the consequences of their activities upon the communities and environment. This case also shows the lack of negotiation between firms, communities, new social movements and governments. Information about externalities and future costs of company activities is crucial but more crucial is formulation and implementation of more sensitive policies to avoid damage to the environment, biodiversity and health of the population. Governmental institutions must be aware that their decisions may affect the quality of life of present and future generations for the sake of a small increment in economic growth and large increase in private benefits of a small group of investors. More informed citizens tend to be more active protestors, such as the case of the students in San Luis. Contact between informed individuals of diverse groups and organizations helps to exchange experiences and create public opinion in favor of mobilization. Community participation and involvement in decision‐making of community development planning is quite limited by the lack of critical information. This fact is critical when the local government cannot provide the right information because there are other interests affecting the process.

Originality/value

The paper highlights the lack of sensitivity of foreign mining companies towards local communities.
