Enhanced layered fog architecture for IoT sensing and actuation as a service

The reduced service cost offered by Sensing and Actuation as a Service paradigm, particularly in Internet of Things (IoT) era, has encouraged many establishments to start without worrying about having their own infrastructure. Such a paradigm is typically managed by a centralized cloud service provider. Fog paradigm has emerged as a mini-cloud that if designed with care to assist the cloud, together will achieve better performance. This article introduces a layered fog architecture called Sensors and Actuator Layered Fog Services Delivery (SALFSD) for IoT ecosystems. The significance of SALFSD is being fault resistant; it dynamically reassigns tasks of the failed node to the nearest active node to maintain the network connection. Besides, SALFSD monitors end users pre-specified cases closer to the physical devices hired by end users to fasten generating the actuation commands. Such node may offload its monitoring responsibility to its parent node in case it is overloaded. SALFSD is evaluated using Yet Another Fog Simulator in different scenarios (numbers of users, sensors, actuators, and areas). A comparison was made for Sensing and Actuating as a Service (SAaaS) with/without layered fog, and layered fog with/without (failure reassignment, pre-specified cases in fog nodes, and offloading). The comparison was conducted in terms of computing/communication latencies and the number of missed messages for both observations and actuation commands. Results show that failure reassignment prevented losing messages and maintained network connectivity. Also, wisely selecting the monitoring fog node per end user pre-specified cases and the offloading scheme decreased actuation latency.

RedHerd: Offensive Cyberspace Operations as a Service

Nowadays, time, scope and cost constraints along with knowledge requirements and personnel training constitute blocking restrictions for effective Offensive Cyberspace Operations (OCO). This paper presents RedHerd, an open-source, collaborative and serverless orchestration framework that overcomes these limitations. RedHerd leverages the ‘as a Service’ paradigm in order to seamlessly deploy a ready-to-use infrastructure that can be also adopted for effective simulation and training purposes, by reliably reproducing a real-world cyberspace battlefield in which red and blue teams can challenge each other. We discuss both the design and implementation of the proposed solution, by focusing on its main functionality, as well as by highlighting how it perfectly fits the Open Systems Architecture design pattern, thanks to the adoption of both open standards and wide-spread open-source software components. The paper also presents a complete OCO simulation based on the usage of RedHerd to perform a fictitious attack and fully compromise an imaginary enterprise following the Cyber Kill Chain (CKC) phases.

Analisis Kualitas Pelayanan Publik Kantor Keuchik Gampong Empee Trieng Berdasarkan Asas Penyelenggaraan Pemerintah Pada Pelayanan Umum

The government is expected to develop a public service paradigm from a centralized service to a service that focuses more on community satisfaction-oriented management. Moreover, the village apparatus (gampong in Acehnese language) as part of the state apparatus has a direct relationship so that they should better understand the living conditions of the people who are within the scope of their administration. In this case, the author takes a case study of the Gampong Empee Trieng Government, where the author performed community service tasks. To meet the demands of excellent administrative services, Gampong government officials are required to provide good services, especially in providing professional services, having work systems and service procedures that are transparent, integrated, responsive, and adaptive to any changes. This study uses a descriptive approach with qualitative research that will provide an overview of how the performance of the Gampong Empee Trieng government in improving the quality of public services for its people. The three principles of government administration that focus on public services will be used as indicators to measure the quality of public services in Gampong Empee Trieng, Darul Kamal District, Aceh Besar District.

WADUL-E AS THE IMPLEMENTATION OF E-SERVICE IN THE NEW PUBLIC SERVICE PARADIGM

This study aims to determine how the application of the New Public Service concept to the WADUL-E Service (Aspiration and Electronic Complaints Forum) in Pacitan Regency. This study used a qualitative approach and the determination of informants using the purposive sampling technique. The results showed that the concept of the New Public Service was not fully applicable to the Pacitan WADUL-E Service, because the researchers did not find data related to the 6th indicator, which is serving not directing which contains the position of the leader here, not as the owner but as a public servant or public servant. However, the rest of the concept of the new public service is in accordance with the real situation in the Pacitan Wadule Service. Hence, it is necessary to have in-depth research to find out the leadership side in the service. Based this research, it can be conculed that it is one of the public innovation efforts created by the Pacitan Regency Government is to provide Complaint Services in the form of WADUL-E Services of Pacitan Regency which was formed and inaugurated on March 14, 2018. By utilizing this service, it is hoped that the aspirations and complaints of the Pacitan citizens are connected to regional government. Keywords: E-Service, New Public Service, WADUL-E Pacitan

Resilienz durch Redundanz/Real-time cloud and edge control of autonomous mobile robots – Resilience through redundacy

Die Auslagerung von Algorithmen auf Edge- und Cloud- umgebungen nach dem Software-as-a-Service-Paradigma bringt viele Vorteile für autonome mobile Roboter mit sich. Es kann jedoch nicht immer garantiert werden, dass die QoS-Anforderungen der ausgelagerten echtzeitkritischen Funktionen erfüllt sind. Das Bereitstellen von redundanten Kommunikationsmöglichkeiten und Berechnungsknoten sowie robotergesteuertes Umschalten ermöglichen Echtzeitfähigkeit innerhalb dieser unsicheren Infrastrukturen.   Deploying navigation algorithms on an edge or cloud server according to the Software-as-a-Service paradigm has many advantages for autonomous mobile robots. However, it cannot always be guaranteed that the QoS requirements of the outsoured real-time critical functions are met. Providing redundant communication channels and computation nodes as well as robot-controlled switching enables real-time capability within these uncertain infrastructures.

Policy Note: A Universal Equity–Efficiency Model for Pricing Water

Drawing on theoretical, practical, and normative rationales, the analysis presented here calls for revisiting the prevailing water service paradigm, and the values and frames it reflects. As is increasingly apparent, current pricing policies may not be sufficiently responsive, pragmatic, or durable, particularly in reconciling competing objectives often cast as the equity–efficiency conundrum. Water is a social good that confers both private and public benefits. The proposed universal (all-inclusive) pricing model envisions five concurrent elements: recognize public functionality in cost allocation (scope economies), calibrate a minimum bill to property assessment (capacity value), provide an essential-use allowance for all households (public health), design cost-based rates for variable water usage (resource management), and prohibit disconnection and deploy service limiters instead (water security). The model advances meaningful structural progress toward social equity while comporting with generally accepted principles to fairly allocate costs and send economic price signals where they make sense.

We Are on the Way: Analysis of On-Demand Ride-Hailing Systems

Problem definition: Recently, there has been a rapid rise of on-demand ride-hailing platforms, such as Uber and Didi, which allow passengers with smartphones to submit trip requests and match them to drivers based on their locations and drivers’ availability. This increased demand has raised questions about how such a new matching mechanism will affect the efficiency of the transportation system—in particular, whether it will help reduce passengers’ average waiting time compared with traditional street-hailing systems. Academic/practical relevance: The on-demand ride-hailing problem has gained much academic interest recently. The results we find in the ride-hailing system have a significant deviation from classic queueing theory where en route time does not play a role. Methodology: In this paper, we shed light on this question by building a stylized model of a circular road and comparing the average waiting times of passengers under various matching mechanisms. Results: We discover the inefficiency in the on-demand ride-hailing system when the en route time is long, which may result in nonmonotonicity of passengers’ average waiting time as the passenger arrival rate increases. After identifying key trade-offs between different mechanisms, we find that the on-demand matching mechanism could result in lower efficiency than the traditional street-hailing mechanism when the system utilization level is medium and the road length is long. Managerial implications: To overcome the disadvantage of both systems, we further propose adding response caps to the on-demand ride-hailing mechanism and develop a heuristic method to calculate a near-optimal cap. We also examine the impact of passenger abandonments, idle time strategies of taxis, and traffic congestion on the performance of the ride-hailing systems. The results of this research would be instrumental for understanding the trade-offs of the new service paradigm and thus enable policy makers to make more informed decisions when enacting regulations for this emerging service paradigm.

ANALISIS FATWA DSN-MUI TENTANG PEDOMAN PENYELENGGARAAN RUMAH SAKIT SYARIAH

On October 1, 2016, DSN-MUI issued the DSN-MUI Fatwa no. 107 / DSN-MUI / X / 2016 concerning Guidelines for the Implementation of Syariah Hospital. This fatwa is based on two reasons, namely the needs of society, and legal vacuum. It was found that the concept of sharia, which is being embodied by the National Sharia Council - The Indonesian Ulema Council (DSN-MUI) in this fatwa still uses a single point of view of the shari'a maqashid of Imam Syatibi, has not yet penetrated its development. Focused on the protection of individuals al-kuliyat al-khamsah, conical to the segmentation of Muslims an sich. Fikih products in the form of this fatwa actually implies the decline of Fikih Indonesia thinking. Considering the condition of the pluralistic Indonesian people should be responded by the development of Shariah thought to al-birr's attitude, oriented to humanity. The best service paradigm in various religious patients.Finally, Sharia attachment to the Hospital is not only limited to marketing methods or name adaptations, but also reflects Islam rahmatan lil a'lamin.

Relationships among employee acting, customer-perceived service quality, emotional well-being and value co-creation

PurposeHinged on the transformative service paradigm, this study investigates the relationships among employee acting, customer-perceived service quality, customer emotional well-being, and their value co-creation. Feelings of gratitude among customers may moderate the effect of perceived service quality on their emotional well-being (i.e., positive and negative affects).Design/methodology/approachA pair study using a structural equation model was conducted to gather data from a financial service organization in a rural area.FindingsThe results show how customers perceive service quality positively impacts their emotional well-being immediately after receiving a financial service, which in turn affects their value co-creation. Hence, feelings of gratitude moderate the effect of perceived service quality on customer positive affect.Originality/valueThis study responds to calls for more studies on how service interactions influence customer well-being in the financial services context. This study is among the few that examine moderation effects of customer feelings of gratitude on their emotional well-being to explain why a positive emotion might sway their short-term well-being.
