A collaborative scheduling method for cloud computing heterogeneous workflows based on deep reinforcement learning

Aiming at the problem of low overall service quality caused by the disordered collaboration of heterogeneous workflows and discontinuous task execution in cloud computing scenarios, this paper proposes a collaborative scheduling method for heterogeneous workflows in cloud computing based on deep reinforcement learning. The method optimizes workflow makespan, cost, fairness and continuity in cloud computing under the constraints of task execution continuity. First, the structure and time sequence features are extracted for the dynamic scheduling process, and a reasonable scheduling decision support feature set is constructed. Second, a time-step adaptive scheduling mechanism is designed to simplify redundant information in the scheduling process and enables the agent to achieve efficient learning. In addition, using equilibrium, priority and preference scheduling strategies, an immediate-lag compound reward mechanism and a scheduling-switching hybrid action are designed to achieve a unification of the agent’s learning objectives and actual scheduling requirements. Finally, by constructing a simulation platform and conducting comparative experiments with four other algorithms, the results show that the proposed method has advantages in collaborative optimization of high-dimensional objectives under task continuity constraints. Including the task loading strategy can optimize the makespan performance by 16.6% and improve the fairness index by 5.3%.

Measuring the Quality of Car Dealership Services from the Point of View of Customers by Applying to the Automotive Sector in the Kingdom of Saudi Arabia

The study aimed to measure the quality of car dealership services from the point of view of customers by applying to the automotive sector in the kingdom of Saudi Arabia to raise the level of car companies’ services and for agencies to achieve the customers’ desires, needs and satisfaction, improve the quality of services, and the possibility of reaching results in improving the quality of services through which recommendations can be proposed Contribute to increasing customer satisfaction. The research problem was the quality of service provided by car dealerships and not the product itself. Low service quality is a selling problem, not a brand problem. Service quality expectations for new car owners have been increasing, increasing pressure on car manufacturers as well as dealerships to provide high-quality products and services. After-sales services and repairs at car dealerships have received much criticism from customers compared to their other purchasing experiences. Customer dissatisfaction with the quality of after-sales services at car dealerships highlighted the importance of providing high-quality services to customers to improve their satisfaction and generate positive behavioral intentions. Since the main objective of the study was to measure the quality of car dealership services from the point of view of customers by applying to the automotive sector in the Kingdom of Saudi Arabia, our study targeted the clients of five of the largest car companies and agencies in the Eastern Province of Saudi Arabia. The design and distribution of the questionnaire designed for this study was distributed to a sample of clients. Due to the large size of the target community, it was also relied upon the method of distributing the questionnaire during the interview, as the use of this method makes the respondents' answers more credible, as well as helps the respondent in answering the various questionnaire axes upon request. The study reached several results, the most important of which are: There is a statistically significant relationship between the quality of the services provided with its dimensions (service tangibility, reliability, response, empathy, safety) and customer satisfaction within the car agencies under study.

Perception and Decision of Public Transport Users in Palu City

Public transport users in Palu City are decreasing every year. The low quality of public transport services is the main reason people are reluctant to use them. Based on this condition, the research was conducted to understand the user’s perceptions and decisions of public transportation services, exceptionally public transport, in Palu City. The method used in this research is the distribution of questionnaires to respondents from 8 sub-districts in Palu City. Data processing on 361 respondents was carried out by descriptive analysis. The results of the study illustrate that the people of Palu City, in general, do not use public transportation (91.9%) for various reasons, including long waiting times (67.2%), unclear routes (43.8%), inadequate stopping places (32.8%), non-uniform fares (8.8), poor vehicle conditions (33.7), poor driver behaviour (7.65), and low level of safety (18.5). The level of satisfaction for users of public transportation is satisfied (31.3%) and for users of private vehicles is not satisfied (41.5%) and uncomfortable (33.7%). The data also shows that 77.3% of respondents use motorcycles in their daily travel activities. This study shows that implementing online applications and free tariffs will increase public transport users by 61.7% dan 70.3%, respectively.

Task offloading using GPU-based particle swarm optimization for high-performance vehicular edge computing

With mobile edge computing, vehicles can obtain nearby network resources and computability and meet the growing demand for vehicular service at large scales. However, as a result of vehicle mobility and offloading of an extensive number of tasks, the congestion in wireless networks and the insufficient computing resources of edge servers make it difficult to maintain good service quality for users. Moreover, network access point selection is not often considered a factor in task execution latency. In this paper, we propose a smart metaheuristic optimization model to address the problem of low service quality due to vehicle movements and limited edge coverage. Then, the proposed model is used to characterize the overall latency of vehicle task offloading by considering resource utilization, workload at edge servers and vehicle movement characteristics. There are two advantages of our proposed framework. First, the design of the optimization model offers an adaptive task offloading strategy by automatically providing preallocation decisions with respect to the edge server workload state. Second, the proposed metaheuristic approach benefits from recent advances in graphics processing unit (GPU) architectures. In fact, the design of the PSO on a GPU shifts the optimization of the task offloading process to a promising area in terms of time and precision. Extensive experimental results are presented to demonstrate the effectiveness of the proposed framework.

Supply regulation under the exclusion policy in a ride-sourcing market

On-demand ride-sourcing platforms have quickly emerged and become ubiquitous in our daily lives. Motivated by the rising public concern about service quality in the ride-sourcing market, this paper aims to examine the impact of exclusion policy that can serve as both quality management and supply regulation strategy. With an exclusion policy, the platform excludes low-quality service providers/drivers from the ride-sourcing market by setting a quality threshold of admission (QTA). We propose a model to describe and analyze the market equilibrium under the exclusion policy and present our analytical and numerical results – some of which are non-intuitive and intriguing. Considering network effects captured by both quality and quantity of service in the market, we find that both the realized supply and total labor welfare are not reduced but rather increase when the platform implements a well-designed exclusion policy. Whereas the platform’s profit, customer surplus, labor welfare, and social welfare are each non-monotonic in the QTA level – first increasing and then decreasing – a moderate level of QTA can benefit all stakeholders (platform, drivers, and passengers) in the market. We also analyze the model with alternative network effects and present the theoretical and numerical results. Using the model, we further identify the principal factors in determining the optimal exclusion policy; these include passengers’ quality preference, labor pool size, and quality differentiation among registered drivers.

Jakość rządzenia, stan psychiczny i postawy wobec rynku i demokracji w krajach Grupy Wyszehradzkiej na tle Europy Północno-Zachodniej

The goals of the study are to: 1. examine the impact of the quality of public service management on the mental state and attitudes towards the market and democracy in the Visegrád Group countries compared to Northwest Europe; 2. identify different mechanisms connecting the quality of governance with the mental state and attitudes towards the market and democracy in both groups of countries and their interpretations in terms of the neo-institutional theory. The quality of governance has been assessed based on the respondents’ opinions about the provision of public services. Low evaluation of the quality of public services and the belief in privileges and corruption in their distribution coexist with a poorer mental state, antimarket attitudes, less trust in democratic institutions and dissatisfaction with democracy.Differences: 1. Institutional exclusivity is relatively greater in the Visegrád Group. Contesting attitudes towards the market and democracy are in a relatively higher degree a consequence of the low quality of services and low incomes. 2. In these countries, public services relatively weakly compensate for income inequalities. 3. In Northwest Europe, contesting attitudes towards democratic and market institutions are the consequence of privileges and corruption in the distribution of services. 4. In the Visegrád Group countries, privileges and corruption are greater, but less frustrating. Institutional exclusiveness is slightly more accepted in the Visegrád Group countries than in Northwest Europe. This state of affairs is the consequence of equipping public administration with resources and cultural patterns. If the administrative resources were the same in all the compared countries, the level of exclusivity would be relatively higher in the Visegrád countries for cultural reasons.

Shuttle Bus Rerouting and Rescheduling Problem considering Daily Demand Fluctuation

In an urban shuttle system, shuttle buses need to pick up passengers waiting at predetermined stops according to their planned schedules (routes and timetables). However, in practice, passenger demand is unstable and has fluctuations, which means that passenger demand at a specific stop is likely to increase or decrease, causing low service quality, long passenger waiting times, and imbalanced utilization of bus capacity. Therefore, we introduce the shuttle bus rerouting and rescheduling strategy, based on which the operator can change the visited stops and arrival times of the shuttle buses and can operate backup buses to handle the passenger demand fluctuations. A three-dimensional space-time-state network is formulated to depict shuttle routes, timetables, and passenger-loading states, and the proposed problem can be formulated as a multicommodity network-flow optimization problem. To solve the model efficiently, we adopt the alternating direction method of multipliers (ADMM) decomposition method to decompose the original problem into several single shuttle routing subproblems. We test the model and algorithm in the 9-node network with three stops, and a larger scale Chicago sketch network is also adopted to demonstrate the effectiveness and efficiency of the proposed model and algorithm. The rerouting and rescheduling results for the Chicago case represent a 5.7% improvement relative to the results with the planned schedules.

A Quality Framework to Address Racial and Ethnic Disparities in Emergency Department Care

The emergency department serves as a vital source of health care for residents in the United States, including as a safety net. However, patients from minoritized racial and ethnic groups have historically experienced disproportionate barriers to accessing health care services and lower quality of services than White patients. Quality measures and their application to quality improvement initiatives represent a critical opportunity to incentivize health care systems to advance health equity and reduce health disparities. Currently, there are no nationally recognized quality measures that track the quality of emergency care delivery by race and ethnicity and no published frameworks to guide the development and prioritization of quality measures to reduce health disparities in emergency care. To address these gaps, the American College of Emergency Physicians (ACEP) convened a working group of experts in quality measurement, health disparities, and health equity to develop guidance on establishing quality measures to address racial and ethnic disparities in the provision of emergency care. Based on iterative discussion over 3 working group meetings, we present a summary of existing emergency medicine quality measures that should be adapted to track racial and ethnic disparities, as well as a framework for developing new measures that focus on disparities in access to emergency care, care delivery, and transitions of care.

The Soviet Union in two Arab novels

The study aims to analyze the representation of the Soviet Union in two Arab novels, “Ice” (2011) by Egyptian Sun‘allah Ibrahim and “Time of the Red Reed Pipe” (2012) by Kuwaiti Thurayya al-Baqsami. Within the vast expanse of the Arab “emigrant” literature one can find relatively few works of fiction that have to do with the USSR despite the fact that in the 1960-1980s thousands of Arab students studied in the country. Among a couple dozen Arab writers who wrote some fiction about the USSR very few spent more than a couple of months in the country, and their works, as a rule, present idealized and rather superficial images of the Soviet Union. Unlike these authors, Sun‘allah Ibrahim and Thurayya al-Baqsami spent in the 1970s quite a long time in Moscow in the status of ordinary students, and for this reason their novels present a much more realistic picture of the Soviet Union. Without any noticeable warmth towards their Soviet hosts, the writers consider many negative features of Soviet social and economic life as commodity shortage, low quality of Soviet goods and services, illegal currency operations, etc. The two authors’ representations of the Soviet Union stand in contrast to the Soviet’s own idea of how the people from the developing countries perceived the “country of victorious socialism.”

Tripartite Evolutionary Game of Agricultural Service Scale Management and Small Farmers' Interests under Government Preferential Policies.

In agricultural production with small farmers as the main body, the service scale operation is one of the ways to obtain scale operation benefits. This paper constructs a tripartite evolutionary game model of agricultural scale service providers (integrators), demand subjects (farmers), and agriculture-related government departments and analyzes the influencing factors, influencing relations, and evolutionary stable equilibrium results of each participant's strategy choice. The results show that improving rewards and punishments and strengthening supervision by agriculture-related government departments will help integrators provide high-quality services and encourage farmers to actively produce and reduce speculation; when the cost difference between high-quality service and low-quality service is large, the probability of high-quality service provided by integrators will be reduced, and the evolution result of low Pareto efficiency may appear in the system; when the speculative cost of farmers is not high, the lobbying efforts of integrators will increase the speculative behavior of farmers. Finally, MATLAB2018a is used to simulate and analyze the validity of the model results, which provides a theoretical reference for the scale operation of agricultural services.

A System Dynamics Approach for Evaluating the Synergy Degree of Social Organizations Participating in Community and Home-Based Elderly Care Services

As the number of elderly continues to increase in China, anxiety about related problems has encouraged special care for the elderly. Social organizations participating in community and home-based elderly care services (SO-CHECS) seem to be a promising way to address these problems, but it also raises new challenges, such as uncoordinated cooperation among stakeholders, which would lead to low elderly care service quality and hinder the active participation of social organizations. However, synergetic development can be introduced to enhance the participation of social organizations and to improve social welfare. Thus, this study utilizes system dynamics (SD) to investigate how the overall synergy degree of the SO-CHECS system is affected by the dynamic interactions of main elements/subsystems of this system. It also provides a practical tool through which the effectiveness of various management measures in improving the synergy degree of SO-CHECS could be simulated in advance so that the key factors that restrict the development of SO-CHECS can be analyzed and potential effective policies can be designed. In this way, knowledge of the synergic development of the SO-CHECS system will help managers or policy makers to form optimal cooperative relationships among collaborative stakeholders, improve satisfaction for the elderly, and achieve high-efficient resource utilization for the whole city.

Analisis Kepuasan Mahasiswa terhadap Pembelajaran Daring di STIKes Baiturrahim Jambi

Distance learning is an alternative to learning in the COVID-19 pandemic era, one of which is by utilizing various learning applications where the educator factor, namely the lecturer, plays a major role. Lecturers must have special skills and abilities, including pedagogical competence, professional competence, personality competence and social competence. The learning carried out by lecturers is like the services provided to consumers or students. In providing services, of course, what must be considered is the quality of the service itself. The high and low quality of service can only be seen by students. When the quality of service exceeds the expectations thought by students, there will be a sense of satisfaction. The description of student satisfaction related to online learning performance by lecturers is very satisfying for all indicators of personality and social competence. The purpose of this study was to describe student satisfaction with online learning at Baiturahim College of Health Sciences. This research is a survey type research with a quantitative approach. The analysis in this study uses descriptive analysis method. The respondents of this study were students of the nursing science study program who took online lectures, namely 81 people which were held from October 2021 to February 2022. The results of the study were obtained. Most (56.8%) were not satisfied with online learning at STIKes Baiturahim. Suggestions for the STIkes Baiturahim Institution to increase the use of information technology in learning methods, especially online, by adjusting the development of information media.

Effects of Social Work Licensure Exemptions: Theoretical Propositions, Evidence, and Research Agendas

Purpose: This article intends to review the literature to address the concern that prevalent licensure exemptions in social work undermine public safety. Methods: It reviews (1) the rationales for licensure exemptions, (2) the effects of exemptions on the public and the social work workforce, and (3) critical gaps in the extant evidence to recommend future research agendas to fill the gaps. Results: A review of the literature revealed that concerns about duplicated regulations and potential labor shortages justified licensure exemptions but with little empirical evidence. Limited evidence was found to support the claim that exemptions minimize the effects of licensure. Extant evidence, albeit scant, implies that licensure may not eliminate lower-quality services but benefit incumbent social workers with higher earnings. Conclusions: Recognizing the gaps in the literature, it recommends empirical research and discusses available data to assess the effects of exemptions on public safety and socioeconomic (in)equity within the workforce.

Application and Performance Evaluation of Resource Pool Architecture in Satellite Edge Computing

Satellites will play a vital role in the future of the global Internet of Things (IoT); however, the resource shortage is the biggest limiting factor in the regional task of massiveequipment in the IoT for satellite service. Compared with the traditional isolated mode of satellite resources, the current research aims to realize resource sharing through satellite cooperation in satellite edge computing, to solve the problems of limited resources and low service quality of a single satellite. We propose a satellite resource pool architecture-oriented regional task in satellite edge computing. Different from fixed servers in ground systems, the satellite orbital motion brings challenges to the construction of the satellite resource pool. After the capacity planning of the satellite resource pool for regional tasks is given, an algorithm based on search matching is proposed to solve the dynamic satellite selection problem. A ground semi-physical simulation system is built to perform experiments and evaluate the performance of three modes of satellite resource sharing: isolated mode, cooperative mode, and pooled mode. The results show that the pooled mode, compared with the isolated mode, improves the task success rate by 19.52%, and at the same time increases network resources and energy consumption in the same scenario. Compared with the cooperation mode, the performance of task success rate and resource utilization rate is close to that of the pooled mode, but it has more advantages in response time and load balancing of satellite resources. This shows that in the IoT, the resource pool is of great benefit as it improves the task response time and improves the load balance of satellite resources without degrading the performance, which makes sense in task-demanding scenarios.

The effect of community engagement on healthcare utilization and health insurance enrollment in Ghana: Results from a randomized experiment

Health insurance enrollment in many Sub‐Saharan African countries is low, even with highly subsidized premiums and exemptions for vulnerable populations. One possible explanation is low service quality, which results in a low valuation of health insurance. Using a randomized control trial in 64 primary health care facilities in Ghana, this study assesses the impact of a community engagement intervention designed to improve the quality of healthcare and health insurance services on households living nearby the facilities. Although the intervention improved the medical‐technical quality of health services, our results show that households' subjective perceptions of the quality of healthcare and insurance services did not increase. Nevertheless, the likelihood of illness and concomitant healthcare utilization reduced, and especially households who were not insured at baseline were more likely to enroll in health insurance. The results show that solely increasing the technical quality of care is not sufficient to increase households' subjective assessments of healthcare quality. Still, improving technical quality can directly contribute to health outcomes and further increase health insurance coverage, especially among the previously uninsured.
