An intelligent and secure system for predicting and preventing Zika virus outbreak using Fog computing

Zika virus is a mosquito-borne disease that spreads very quickly in different parts of the world. In this article, we proposed a system to prevent and control the spread of Zika virus disease using integration of Fog computing, cloud computing, mobile phones and the Internet of things (IoT)-based sensor devices. Fog computing is used as an intermediary layer between the cloud and end users to reduce the latency time and extra communication cost that is usually found high in cloud-based systems. A fuzzy k-nearest neighbour is used to diagnose the possibly infected users, and Google map web service is used to provide the geographic positioning system (GPS)-based risk assessment to prevent the outbreak. It is used to represent each Zika virus (ZikaV)-infected user, mosquito-dense sites and breeding sites on the Google map that help the government healthcare authorities to control such risk-prone areas effectively and efficiently. The proposed system is deployed on Amazon EC2 cloud to evaluate its performance and accuracy using data set for 2 million users. Our system provides high accuracy of 94.5% for initial diagnosis of different users according to their symptoms and appropriate GPS-based risk assessment.     

The mediating effect of information availability between organization design variables and environmental practices in the Canadian hotel industry

This study examines whether providing employees with information about environmental impacts, industry practices, technologies, regulations and benchmarking of environmental practices mediates the influence of organization design variables on environmental impact reduction. The study finds that both organization design variables (discretionary slack, coordination mechanisms and performance evaluation) and information availability have a direct influence on environmental impact reduction practices in the Canadian hotel industry. However, information availability partially mediates the influence of organization design variables, indicating that effecting changes in organization design alone may be less effective in generating proactive environmental practices without providing employees with information and benchmarking of industry environmental practices.

CEO's empathy and salience of socioemotional wealth in family SMEs – The moderating role of external directors

A focus on preserving socioemotional wealth may influence entrepreneurial activities in family firms. In this paper, we identify the emotion of empathy in the family CEO as an antecedent of socioemotional wealth creation. We argue that the presence of one or more external directors can have a direct as well as moderating influence on the relationship between CEO's empathy and the salience of socioemotional wealth to the family CEO. Our empirical tests confirm these hypotheses. Several areas of future research are suggested to incorporate empathy and other emotions in family business studies.     

The Role of Retail Competition,Demographics and Account Retail Strategy as Drivers of Promotional Sensitivity

We study the determinants of sensitivity to the promotional activities of temporary price reductions, displays, and feature advertisements. Both the theoretical and empirical literatures on price promotions suggest that retailer competition and the demographic composition of the shopping population should be linked to response to temporary price cuts. However, datasets that span different market areas have not been used to study the role of retail competition in determining price sensitivity. Moreover, little is known about the determinants of display and feature response. Very little attention has been focused on retailer strategic decisions such as price format (EDLP vs. Hi-Lo) or size of stores. We assemble a unique dataset with all U.S. markets and all major retail grocery chains represented in order to investigate the role of retail competition, account retail strategy, and demographics in determining promotional response. Previous work has not simultaneously modeled response to price, display, and feature promotions, which we do in a Bayesian Hierarchical model. We also allow for retailers in the same market to have correlated sales response equations through a variance component specification. Our results indicate that retail strategic variables such as price format are the most important determinants of promotional response, followed by demographic variables. Surprisingly, we find that variables measuring the extent of retail competition are not important in explaining promotional response.     

The evolution of Indian accounting standards: Its history and current status with regard to International Financial Reporting Standards

This paper addresses the adoption and applicability of International Accounting Standards (IAS) and International Financial Reporting Standards (IFRS), issued by the International Accounting Standards Board (IASB) to India. Specifically, the paper highlights some major areas where the country lacked harmonization with IAS in 1993 and the rapid congruence with IAS in the decade that followed. The attempt to achieve congruence with IAS appears to be more a by-product of the country's rapid economic growth rather than its catalyst. However, continued growth and the attraction of foreign capital to domestic ventures will depend on the transparency of the financial dealings. The Institute of the Chartered Accountants of India, (ICAI), India's standard setting body, is increasingly attempting to provide this transparency by revisions and additions to accounting standards, and by Exposure Drafts which aim to bring India more in line with International Financial Reporting Standards.     

An investigation of risk and return in forward foreign exchange

This paper examines the determination of risk premiums in foreign exchange markets. The statistical model is based on a theoretical model of asset pricing, which leads to severe cross-equation constraints. Statistical tests lead to a rejection of these constraints. We examine the robustness of these tests to time variation in parameters and to the presence of heteroskedasticity. We find that there is evidence for heteroskedasticity and that the conditional expectation of the risk premium is a nonlinear function of the forward premium. Accounting for this nonlinearity, the specification appears to be time invariant. Out of sample portfolio speculation is profitable but risky.     

The informational relevance of corporate social responsibility: evidence from DS400 index reconstitutions

This study examines the relationship between corporate social responsibility and financial performance by analyzing the intra‐industry wealth impact of additions and deletions to the Domini Social 400 index. Results from the event study analysis indicate that additions to the index generate a positive share price response for the announcement firm and a negative response by rival firms. The opposite reaction is observed for index deletions. Additionally, the share price response is more pronounced for informationally opaque industries. Our study highlights the importance of external monitoring agencies in providing meaningful information that helps resolve investor uncertainty regarding the quality of a firm's relationships with its primary stakeholders.
