As CRM concerns managing customer knowledge, it can be considered as a subset of Knowledge Management (KM). Therefore, in this study, the effort has been made to propose a Customer Knowledge Management (CKM) process model to compensate the existing lack of a study integrating CRM and KM with the aim of customer value augmentation. In this CKM model, all forms of CRM are employed to support all the phases of CKM. Finally, a home appliances case is studied to illustrate the proposed CKM model.

Various constellations of oil actors-including corporations and nations-have shaped seemingly disconnected and geographically distant landscapes, cities, and buildings around the world over the last 150 years. Corporate, public, and popular media have publicized these cycles of spatializing oil. Together, construction and representation have created what is here collectively identified as a global palimpsestic petroleumscape. Based on archival research and a flourishing literature of secondary sources, this article applies the concept of the petroleumscape to two case studies in Iran and identifies two patterns of spatializing oil. First, in the southern region of Khuzestan, it tracks Iran's modern transformation under the influence of British Petroleum (BP) , when oil and governmental interests built a complete support landscape. Then, in the capital Tehran, it investigates how US players helped shape the petroleumscape between 1953 and 1979, in line with US styles of consumption, car use, and urban development.

A perusal of the literature on housing debates reveals that the term ‘value’ is mostly applied to express the financial value of a house and is dealt with in economic literature. However, an alternative meaning of the word ‘value’ in the housing literature can be found in research into the values underlying housing preferences, applying research methods from the marketing literature. The explicit combination of moral values and housing policy and design is found neither in the academic housing nor in the philosophical literature. However, diving deeper into the housing debate reveals that there are a host of moral values already present throughout this debate that are often not explicitly articulated and explicated, such as inclusiveness, sustainability, autonomy, and security. The aim of this paper is to address the role of values in housing policy and design. By doing so, we apply the Design for Values approach (DfV). We argue that the DfV approach can help to make implicit moral values more explicit, which can improve the housing debate, housing policy-making, and housing design. The paper first explores which values are relevant for housing policy and design and operationalizes those values. Next, the paper describes key debates in housing such as: What is “adequate housing” in times of rapid urbanization and increasing house prices? We argue that by exploring the underlying values of these debates, stakeholders can create a better understanding of the current (lack of) fundamental discussions on housing issues

Abstract. Due to the importance of providing security in satellite imagery and their transmission, in this paper, a new method for encrypting satellite images based on Hash key-based symmetric cryptographic algorithm is proposed which is developed by combining the generated key and chaos mapping parameters. The benefits of this algorithm are high security, high sensitivity and using dynamic encryption blocks. The proposed algorithm consists of three main parts: in the first section, the encryption key is created using the SHA-512 Hash function. In the second section, the initial values and the parameters of the mapping Chaos are determined by the algebraic functions that are related to the primary key. In the third section, with the help of the encryption block, the encrypted image is finally obtained. The purpose of this article is to increase the security of encrypting satellite images by creating an unspecified encryption block to deal with a variety of attacks. In this regard, both aspects of security and performance of the proposed algorithm have been analysed and the results are evaluated.
