"This book constitutes the refereed proceedings of the International Conference on Privacy in Statistical Databases, PSD 2012, held in Palermo, Italy, in September 2012 under the sponsorship of the UNESCO chair in Data Privacy. The 27 revised full papers presented were carefully reviewed and selected from 38 submissions. The papers are organized in topical sections on tabular data protection, microdata protection, methods and disclosure risk, microdata protection : case studies, spatial data protection, differential privacy, on-line databases and remote access, privacy-preserving protocols."

"This SpringerBrief discusses the applications of spare representation in wireless communications, with a particular focus on the most recent developed compressive sensing (CS) enabled approaches. With the help of sparsity property, sub-Nyquist sampling can be achieved in wideband cognitive radio networks by adopting compressive sensing, which is illustrated in this brief, and it starts with a comprehensive overview of compressive sensing principles. Subsequently, the authors present a complete framework for data-driven compressive spectrum sensing in cognitive radio networks, which guarantees robustness, low-complexity, and security. Particularly, robust compressive spectrum sensing, low-complexity compressive spectrum sensing, and secure compressive sensing based malicious user detection are proposed to address the various issues in wideband cognitive radio networks. Correspondingly, the real-world signals and data collected by experiments carried out during TV white space pilot trial enables data-driven compressive spectrum sensing. The collected data are analysed and used to verify our designs and provide significant insights on the potential of applying compressive sensing to wideband spectrum sensing. This SpringerBrief provides readers a clear picture on how to exploit the compressive sensing to process wireless signals in wideband cognitive radio networks. Students, professors, researchers, scientists, practitioners, and engineers working in the fields of compressive sensing in wireless communications will find this SpringerBrief very useful as a short reference or study guide book. Industry managers, and government research agency employees also working in the fields of compressive sensing in wireless communications will find this SpringerBrief useful as well."

"This book constitutes the thoroughly refereed post-conference proceedings of the First International Workshop on Energy Efficient Data Centers (E2DC 2012) held in Madrid, Spain, in May 2012. The 13 revised full papers presented were carefully selected from 32 submissions. The papers cover topics from information and communication technologies of green data centers to business models and GreenSLA solutions. The first section presents contributions in form of position and short papers, related to various European projects. The other two sections comprise papers with more in-depth technical details. The topics covered include energy-efficient data center management and service delivery as well as energy monitoring and optimization techniques for data centers."

"ABSTRAKPenelitian ini bertujuan untuk menjelaskan konsep knowledge sharing dalam jaringan komunikasi yang dilakukan oleh organisasi, dalam meningkatkan kapasitas pengetahuan tacit dan explicit para anggotanya guna kesiapan menghadapi kemajuan teknologi informasi dan komunikasi. Objek penelitian ini adalah Iprahumas, yaitu organisasi profesi yang menaungi dan hanya beranggotakan pranata humas di seluruh Indonesia. Iprahumas merupakan mitra kerja Kementerian Komunikasi dan Informatika sebagai instansi Pembina Jabatan Fungsional Pranata Humas di Indonesia. Iprahumas mempunyai peran yang strategis dalam mendukung tugas dan fungsi profesi pranata humas untuk melakukan pelayanan informasi dan kehumasan pemerintah. Sebaran anggota Iprahumas di seluruh Indonesia juga menjadi pendukung dalam diseminasi narasi tunggal maupun membangun partisipasi publik. Penelitian ini menggunakan teori-teori yang menjelaskan konsep knowledge sharing dan teori jaringan komunikasi. Penelitian ini menggunakan paradigma post-positivist dengan pendekatan penelitian campuran (mix method) dimana kualitatif sebagai metode utama. Teknik pengumpulan data didapatkan melalui wawancara mendalam, observasi, kuesioner, dan studi literatur. Hasil penelitian menunjukkan bahwa dari efektivitas pengelolaan aktivitas knowledge sharing yang sudah dilaksanakan oleh Iprahumas, penerapan identity, reflect, share, dan apply belum dilakukan secara maksimal. Begitu pula dengan bentuk jaringan komunikasi anggota Iprahumas dalam efektivitas organisasi knowledge sharing. Dari jaringan komunikasi yang diteliti, mayoritas hubungan ikatan yang terjadi dalam jaringan komunikasi anggota Iprahumas bersifat satu arah. Jaringan komunikasi aktivitas knowledge sharing terkait tema umum maupun tema-tema knowledge sharing existing di Iprahumas cenderung tidak menyebar dan dapat berdampak pada kurang efektifnya penyebaran pengetahuan yang merata antar anggota.

ABSTRACTThis study aims to explain the concept of knowledge sharing in communication networks carried out by organizations, in increasing the tacit and explicit knowledge capacity of its members for readiness to face the advancement of information and communication technology. The object of this research is Iprahumas, which is a professional association that houses and only consists of public relations institutions throughout Indonesia. Iprahumas is a working partner of the Ministry of Communication and Informatics as a Public Relations Institution Position Trustee agency in Indonesia. Iprahumas has a strategic role in supporting the duties and functions of the public relations institution profession to provide information and public relations services to the government. The distribution of members of Iprahumas throughout Indonesia has also become a supporter in the dissemination of a single narrative and in building public participation. This study uses theories that explain the concept of knowledge sharing and communication network theory. This study uses a post-positivist paradigm with a mixed research approach where qualitative is the main method. Data collection techniques were obtained through in-depth interviews, observation, questionnaires, and literature studies. The results showed that from the effectiveness of the management of knowledge sharing activities that have been carried out by Iprahumas, the application of identity, reflect, share and apply has not been done to the fullest. This is also the case with the communication network of Iprahumas members in the effectiveness of knowledge sharing organizations. From the communication network under study, the majority of the bond relationships that occur in the Iprahumas member communication network are one-way. The communication network of knowledge sharing activities related to common themes and existing knowledge sharing themes at Iprahumas tends not to spread and can have an impact on the ineffectiveness of knowledge sharing that is evenly distributed among members."
