Model Approach

Green cloud computing aims at a processing infrastructure that combines flexibility, quality of services, and reduced energy utilisation. In order to achieve this objective, the management solution must regulate the internal settings to address the pressing issue of data centre over- provisioning related to the need to match the peak demand. In this context, we propose an integrated solution for environment, services and network management based on organisation model of autonomous agent components. This work introduces the system management model, analyses the system’s behaviour, describes the operation principles, and presents a case study scenario and some results. We extended CloudSim to simulate the organisation model approach and implemented the migration and reallocation policies using this improved version to validate our management solution.

The issue of information management is crucial for any academic institution. Convenient access to requested content is creating a competitive advantage for different types of decisions. Information management process in Institut Pendidikan Guru (IPG) often create problems because there is no systematic way of storage management. IPG lecturers stored their teaching materials in different kind of methods. This situation cause in a loss of resources, difficult to retrieve and also cannot be identified when it's needed. Dealing with large volumes of resources it is essential to use technological solutions that enable flexible storage, retrieval, processing and interpreting information. To solve the problems, this article introduced a framework that use single platform and named as Information Sharing for Learning (IS4L) for managing teaching and learning resources in IPG. The resources will be stored and can be accessed at any time. The framework also applied the technique of gamification to motivate and encourage users to use the application and consequently will increase the volume of resources stored. The developed application based on the proposed framework could help to motivate and engage peoples to share their resources and enhance quality of services in IPG. Finally it could assist to improve the performance and effectiveness of services to achieve users’ satisfaction.

This paper uses Singapore as a case study to illustrate how staffing policies and practices affect the quality of the workforce which ultimately influence performance at employee and organization level. It reveals that Singapore public service has been able to put in place most of the ‘critical factors’ for an effective staffing system management. The presence of those critical factors have played an important role in making Singapore to be one of the most effective public services in the world. Finally, it forwards theoretical and practical implications of the study and future research direction.

Vincentius Kristus Raja (KR) Main Clinic aims to serve patients effectively and economically in an effort to improve the quality of public health services, especially in Surabaya. This type of research is descriptive qualitative in the form of a case study, to assess the implementation of standard operating procedures at the Vincentius Kristus Raja Main Clinic. Relevant data collection was carried out using questionnaires distributed to personnel related to standard operating procedures. The results of the research study according to the questionnaire indicate that the operational implementation is in accordance with the standard operating procedures that have been set based on the policies of the leadership and the Vincentius Kristus Raja Main Clinic Foundation. Compliance with standard operating procedures is very important because standard operating procedures are guidelines or references for carrying out tasks and work in accordance with their functions. The conclusions and suggestions from this study are that although compliance with standard operating procedures is adequate, the Vincentius Kristus Raja Main Clinic needs to develop and improve the quality of services, especially better communication with patients, both new patients and patients who have been on treatment for a long time at the Vincentius Kristus Raja Main Clinic. Considering that there are now many new health clinics that can be competitors for the Vincentius Kristus Raja Main Clinic, there must be a good response to this phenomenon. The emergence of these new competitors requires the Vincentius Kristus Raja Main Clinic to be able to be competitive in order to face the existing competition by improving the quality and quality of service for patients.

Resource sharing problem is one of the most important aspects of Cloud architectures whose primary goal is to fully enable the concept of accessing computing resources on-demand. Access control and resource federation are hot research topics and a lot of open issues should be addressed on functionalities, technological interoperability, quality of services and security of the federated infrastructures. This chapter aims at offering a view on the problems of access control on federated Clouds; since they strongly depend on chosen architectures and platforms, the chapter will discuss some solutions applied on a real case study: the PerfCloud framework, which is based on the integration of Grid and Cloud platforms. The proposed architecture is based on the adoption of an interoperability system to cope with identity federation and access control, it is strictly related to the adopted framework nevertheless it helps the reader to have an idea of the involved open issues and available solutions in commercial or experimental clouds.

In this chapter, the authors present some of the latest developments related to the provisioning of Quality of Service (QoS) in today’s networks and the associated network management structures that are or will be deployed to support them. They first give a brief overview of the most important Quality of Service proposals in the areas of Layer 2 (L2) and Layer 3 (L3) QoS provisioning in backbone networks, and they discuss the network management structures and brokers that have been proposed in order to implement these services. As a case study, they describe the pan-european research and academic network, which is supported centrally by GEANT and which encompasses multiple independent NRENs (National Research and Education Networks). In the last few years, GEANT has developed and deployed a number of production and pilot services meant for the delivery of quality network services to the end users across Europe.

Fully homomorphic encryption schemes (FHE) are a type of encryption algorithm dedicated to data security in cloud computing. It allows for performing computations over ciphertext. In addition to this characteristic, a verifiable FHE scheme has the capacity to allow an end user to verify the correctness of the computations done by a cloud server on his encrypted data. Since FHE schemes are known to be greedy in term of processing consumption and slow in terms of runtime execution, it is very useful to look for improvement techniques and tools to improve FHE performance. Parallelizing computations is among the best tools one can use for FHE improvement. Batching is a kind of parallelization of computations when applied to an FHE scheme, it gives it the capacity of encrypting and homomorphically processing a vector of plaintexts as a single ciphertext. This is used in the context of cloud computing to perform a known function on several ciphertexts for multiple clients at the same time. The advantage here is in optimizing resources on the cloud side and improving the quality of services provided by the cloud computing. In this article, the authors will present a detailed survey of different FHE improvement techniques in the literature and apply the batching technique to a promising verifiable FHE (VFHE) recently presented by the authors at the WINCOM17 conference.

A common characteristic of Roma as a cultural group is that they do not allow their elderly to die alone. Nevertheless, rooted in a mainstream cultural perspective of health provision services, public institutions usually do not allow Roma people to be with their loved ones in their last moments. Following the communicative methodology, we conducted a communicative case study on the death of the most relevant female Roma leader in Catalonia. She was accompanied by more than two hundred family members and friends in her room and corridor at an important hospital in Barcelona. We performed our research in the 2 years following her death to obtain the reflections of the Roma members involved. These reflections revealed the egalitarian dialogue forged between these Roma members and the hospital personnel, which enabled the former to embrace their culture and support their loved ones before death. Because this dialogue was possible and fruitful, the acknowledgment of cultural diversity and the improvement of the quality of services offered to Roma might also be possible in other health institutions.

Ever-growing digital services determine libraries to update almost all of their activities. Traditional library services must be transformed into electronic libraries, and library specialists must always be prepared for advanced digital services to come. Thus, libraries in the digital era must offer digital deposit services, digitisation services, research data management, metadata creation, digital cataloguing and conserving, and counselling in what regards digital copyrights, informational alphabetising. In this article, the emphasis falls on the necessity of developing and transforming libraries, bringing awareness to their role and their importance for society and at an individual level.

Aims: This article aims to analyze the main factors that influence the performance of the governance of Producers' Organizations in the context of the Uniform Act of OHADA devoted to the Law on cooperative societies. Study Design: The case study is based on Village Cotton Producers Cooperatives (CVPCs). Governance performance of CVPCs referred to and has been measured through respectively quality of internal governance (administrative) and quality of services provided to members. Place and Duration of Study: The study has been carried out in the Department of Alibori, northern Benin Republic. Data collection period run from July to October 2019. Methodology: We included 242 CVPCs selected in the six municipalities in the Department of Alibori. Primary data relating to socio-economic characteristics (the size of the CVPC, the age, the proportion of women in group, profile of leaders), and governance parameters related to internal governance and the quality of services provided to members. Results: The results revealed that internal governance is generally poor and the quality of services provided to members is good. The proportion of women and the profile of leaders determine (bad) internal governance compared to good governance. The low profile of the leaders, the small size and the low proportion of women determine the quality of the services provided to members. The more the profile of leaders improves, the more likely it is to have good governance. On the other hand, the more the proportion of women in CVPCs increases, the more there is a chance of having bad internal governance rather than good governance. Conclusion: These results suggest that the lower or medium the profile of leaders, the poorer or average internal governance and services provided to members will be. A better combination of all these determinants will improve both the quality of internal governance and the services provided to members in a CVPC.
