This research paper aims to investigate smart contracts and Blockchain technology to build a privacy-sensitive application focusing on a Digital Medication Plan (DMR) containing prescriptions. The DMR is used just as a use case. However, the proposed model applies to any context where confidential information is shared and authentication or proof of validity is necessary. We start by presenting the problem to understand the necessity of digitalizing the medication plans and how Blockchain technology fits to implement this application. After that, we explain Blockchain technology, a recent and comparatively unknown IT solution. Later we propose a design to solve the problem, and we develop a System of Smart Contracts to demonstrate how to build similar applications and suggest policies for Blockchain system design to satisfy the defined requirements. Eventually, we discuss the pertinence of multiple Blockchain solutions in handling the privacy problem. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
Impact of religious tourism on the economic development, energy consumption and environmental degradation: evidence from the Kingdom of Saudi Arabia
مارس 01, 2023
Purpose: Saudi Arabia is the main destination of religious tourism, as it has many spiritual places. With the passage of years, the figures for pilgrim visits are increasing, which is contributing to the economic growth of the Kingdom of Saudi Arabia (KSA). However, pilgrims’ visits can create strong opportunity costs in the form of environmental degradation. Owing to these notions, this study aims to discover the impact of religious tourism on the quality of the natural environment of Saudi Arabia. Design/methodology/approach: This study develops the empirical relationship between the variables by sampling the data from 35 years ranging from 1986 to 2020. The regression among variables was checked by using fully modified ordinary least square and dynamic ordinary least square models. Findings: This analysis proves that religious tourism has a direct impact on the environmental degradation of KSA. The unceasing visits of pilgrims accelerate various economic operations and activities, e.g. assimilation and digestion of industrial products, that necessarily hamper the environmental quality. In addition, this analysis indicates a negative impact on financial development, foreign investment and renewable energy consumption while the positive impact of fossil fuels assimilation and economic expansion on the secretion of CO2. The statistical findings are robust and verify the pollution halo hypothesis while rejecting the Environmental Kuznets Curve model in this region. Research limitations/implications: This analysis recommends restructuring the policies on hajj and Umrah visits. KSA Government should ensure green consumption by pilgrims. The limitation on pilgrims’ visits and the introduction of quotas are alternative policies to impede the pollution in this region. Originality/value: By controlling the routine determinants, this study offers innovative thoughts regarding the consequences of religious tourism on environmental quality.

Purpose: This paper aims to focus on the utilization of retention contracts to screen and discipline managers in a context in which the council, board of directors, possesses incomplete information about the consequences of managers’ decisions. The analysis enlightens us on empire building, on the slight connection between achievement and firing, and describes concerns about the belief that low achievements result from bad managers. Design/methodology/approach: This paper analyzes a basic model to show the resulting dilemmas. The desire to screen managers to enhance the organization's future well-being motivates managers to show their credentials by becoming excessively active. The council can address this bias by firing a manager whose project is proven to ruin value. Moreover, the council can replace the manager if he has implemented a project but its outcomes remain unobservable. Both decisions decrease the attraction to develop loss-generating projects. However, the dismissing decision on either ground will affect the council deduction that the expected competence of the incoming manager is lower than that of the dismissed manager. Findings: This study shows in which situation the selection option is preferred over the disciplining option using two different retention contracts: optimistic contract and pessimistic contract. Originality/value: This study shows in which situation the selection option is preferred over the disciplining option using two different retention contracts: optimistic contract and pessimistic contract.

This study copes with a class of principal-agent problems where information asymmetry represents an important characteristic. The paper examines the relationship between the principal and agents. The principal has to perform two agents’ screening and discipline tasks. To complete his duties, the principal lacks complete information concerning the agents’ behavior and rarely has partial information regarding the failure or success of launched tactics, alliances, rationalization, etc. We analyze the type of retention contracts (implicit) used by the principal to replace or retain agents. Consistent with literature findings, we demonstrated that agents could be extremely active in showing their competencies; the relationship between dismissal and bad performance is invalid; and occasionally, the principal dismisses qualified agents. Then we determined the rules under which electorates urge political parties to acquire information and choose optimal policies from the voter’s viewpoint.

Usually, data quality is defined by multiple attributes that allow classifying the output data (such as completeness, freshness, and accuracy) or the methods exploiting these data (such as dependability, performance, and protection). Among the suggested quality attributes, we will discuss one of the principal categories: data accuracy. Scientific experiments, decision–making, and data retrieval are examples of situations that require a formal evaluation approach to data accuracy. The evaluation approach should be adaptable to distinct understandings of data accuracy and distinct end-user expectations. This study investigates data accuracy and defines dimensions and metrics that affect its evaluation. The investigation of data accuracy generates problems in the user expectation specification and database quality models. This work describes our proposed approach for data accuracy evaluation by defining an evaluation algorithm that considers the distribution of inaccuracies in database relations. The approach decomposes the query output in accordance with data accuracy, labels every part with its accuracy value, and addresses the possibility of enforcing data accuracy by using these values. This study mainly contributes by proposing an explicit evaluation of quality attributes of data accuracy, a formal evaluation approach to data accuracy, and suggesting some improvement actions to reinforce data accuracy. © 2022 Slovene Society Informatika.

This paper proposes a formal model to manage the impact of asymmetric information in decision-making by using principal-agent problems in which an agent (who has incomplete information) must decide to perform or not perform a task on behalf of the principal. After performing a complex (simple) task, the agent underrates (overrates) his competence. As a consequence of underestimation, a competent agent may decide to stop performing the task henceforth. The agent infers his competence from his productivity on a performed task. However, the productivity depends on both the agent's competence and the task complexity. To avoid this situation, the company appoints a mentor (fully informed superior agent) who can determine the task complexity and assess the agent's competence. Accordingly, the mentor matches the task complexity perfectly with the agent's competence. In cases where the mentor and the junior have different preferences, the mentor may not confess all information to the agent. Nevertheless, the mentor desires the agent to fulfill the task. This paper proposes a solution for all of these situations by using a mathematical model. The model assesses the agent's competence based on his productivity and the mentor's appraisal and assists the agent in making the right decision.

Henceforth, users agreed on the necessity of continuous Internet connection independently of the place, the manner, and the time. Nowadays, several elite services are accessible by people over the Internet of Things (IoT), which is a heterogeneous network defined by machine-to-machine communication. Despite the fact that the devices are used to establish the communication, the users can be considered as the actual producers of input data and consumers of the output data. Consequently, the users should be viewed as a smart object in IoT; therefore, user identification, authentication, authorization are required. However, the user identification process is too complicated because the users are worried to share their confidential and private data. on the other hand, this private data should be used by some of their devices. Accordingly, an equitable mechanism to identify users and manage their identities is necessary. In addition, the user plays an extreme important role in the establishment of rules needed for identity identification and in ensuring the continuity of receptive services.The main purpose of this paper is to develop a new framework for Identity Management System (IdMS) for IoT. The primary contributions of this paper are: the proposition of a device recognition algorithm for user identification, the proposition of a new format for the identifier, and a theoretical framework for IdMS.

This paper describes the identity management system (IdMS) by defining system and user requirements. Additionally, it introduces the IdMS concept that approaches the things identity management. Moreover, the paper deeply describes the IdMS features using unified modelling language (UML) diagrams such as class, system, and sequence diagrams to show the main system functionalities. Ultimately, the suggested system is evaluated by comparing it with the existing systems and discussing the fulfilment of user and system requirements.
