Judicial Opinions 123-127

Opinion 123 places the epithet of the name Aeromonas punctata on the list of rejected epithets and clarifies the citation of authors of selected names within the genus Aeromonas. Opinion 124 denies the request to place Borreliella on the list of rejected names because the request is based on a misinterpretation of the Code, which is clarified. There are alternative ways to solve the perceived problem. Opinion 125 denies the request to place Lactobacillus fornicalis on the list of rejected names because the provided information does not yield a reason for rejection. Opinion 126 denies the request to place Prolinoborus and Prolinoborus fasciculus on the list of rejected names because a relevant type strain deposit was not examined. Opinion 127 grants the request to assign the strain deposited as ATCC 4720 as the type strain of Agrobacterium tumefaciens, thereby cor-recting the Approved Lists. These Opinions were ratified by the voting members of the International Committee on Systematics of Prokaryotes

Tret personaliti dan faktor pemilihan kategori pekerjaan dalam kalangan pelajar kolej vokasional

Kajian ini mengkaji tret personaliti dan faktor pemilihan kategori pekerjaan dalam kalangan pelajar tahun dua Diploma Vokasional Malaysia di Kolej Vokasional dari negeri Johor. Kajian ini menggunakan Teori Tipologi Kerjaya Holland (1973) bagi mengenalpasti tret personaliti dan faktor utama yang mendorong pemilihan kerjaya para pelajar di kolej vokasional. Seramai 104 orang telah menurut serta di dalam kajian ini yang terdiri daripada pelajar tahun 2 Diploma Vokasional Malaysia yang menggunakan persampelan secara rawak. Alat kajian Self�Directed Search (SDS)-Form Eassy digunakan bagi meninjau tret personaliti responden, manakala item bagi faktor yang mendorong pemilihan kategori pekerjaan pelajar dibangunkan sendiri orang pengkaji. Analisis data deskriptif yang diperolehi menunjukkan bahawa faktor utama dalam pemilihan kerjaya responden adalah faktor minat. Dapatan kajian juga menunjukkan profil personaliti keseluruhan responden adalah S(sosial), I(investigatif) dan R(realistik). Ciri-ciri bagi kategori kerjaya ini adalah minat terhadap aktiviti-aktiviti yang berkaitan dengan memanipulasi orang lain seperti memberitahu, melatih, mendidik, menghindari aktiviti yang eksplisit, berstruktur serta aktiviti yang melibatkan bahan, peralatan dan mesin. Analisis Independent Sample T-test digunakan bagi melihat perbezaan yang signifikan di antara faktor yang mempengaruhi pemilihan kerjaya responden. Dapatan kajian menunjukkan terdapat perbezaan yang signifikan di antara faktor minat yang mempengaruhi pemilihan kerjaya responden. Kesimpulan dari kajian ini adalah pemilihan kategori pekerjaan pelajar-pelajar di kolej vokasional adalah SIR iaitu berupaya bekerja dengan orang lain dengan keupayaan kemahiran berfikir yang boleh diaplikasikan dalam kerja-kerja kemahiran bersesuaian bidang pengajian teknologi yang dipilih. Selain daripada itu minat merupakan faktor utama dalam pemilihan bidang dan pelajar-pelajar ini telah bersedia untuk menceburi bidang kerjaya yang selari dengan bidang pengajian. Kepentingan kajian ini boleh menjadi sebahagian dari rujukan bagi pemilihan bidang pengajian kepada pelajar-pelajar yang memilih TVET sebagai laluan kerjaya

A Survey of Social Network Analysis Techniques and their Applications to Socially Aware Networking

Socially aware networking is an emerging research field that aims to improve the current networking technologies and realize novel network services by applying social network analysis (SNA) techniques. Conducting socially aware networking studies requires knowledge of both SNA and communication networking, but it is not easy for communication networking researchers who are unfamiliar with SNA to obtain comprehensive knowledge of SNA due to its interdisciplinary nature. This paper therefore aims to fill the knowledge gap for networking researchers who are interested in socially aware networking but are not familiar with SNA. This paper surveys three types of important SNA techniques for socially aware networking: identification of influential nodes, link prediction, and community detection. Then, this paper introduces how SNA techniques are used in socially aware networking and discusses research trends in socially aware networking

An Improved Active Network Concept and Architecture for Distributed and Dynamic Streaming Multimedia Environments with Heterogeneous Bandwidths

A problem in todays Internet infrastructure may occur when a streaming multimedia application is to take place. The information content of video and audio signals that contain moving or changing scenes may simply be too great for Internet clients with low bandwidth capacity if no adaptation is performed. In order to satisfactorily reach clients with various bandwidth capacities some works such as receiver-driven multicast and resilient overlay networks (RON) have been developed. However these efforts mainly call for modification on router level management or place additional layer to the Internet structure, which is not recommended in the nearest future due to the highly acceptance level and widely utilization of the current Internet structure, and the lengthy and tiring standardization process for a new structure or modification to be accepted. We have developed an improved active network approach for distributed and dynamic streaming multimedia environment with heterogeneous bandwidth, such as the case of the Internet. Friendly active network system (FANS) is a sample of our approach. Adopting application level active network (ALAN) mechanism, FANS participants and available media are referred through its universal resource locator (url). The system intercepts traffic flowing from source to destination and performs media post-processing at an intermediate peer. The process is performed at the application level instead of at the router level, which was the original approach of active networks. FANS requires no changes in router level management and puts no additional requirement to the current Internet architecture and, hence, instantly applicable. In comparison with ALAN, FANS possesses two significant differences. From the system overview, ALAN requires three minimum elements: clients, servers, and dynamic proxy servers. FANS, on the other hand, unifies the functionalities of those three elements. Each of peers in FANS is a client, an intermediate peer, and a media server as well. Secondly, FANS members tracking system dynamically detects the existence of a newly joined computers or mobile device, given its url is available and announced. In ALAN, the servers and the middle nodes are priori known and, hence, static. The application level approach and better performance characteristics distinguished also our work with another similar work in this field, which uses router level approach. The approach offers, in general, the following improvements: FANS promotes QoS fairness, in which clients with lower bandwidth are accommodated and receive better quality of service FANS introduces a new algorithm to determine whether or not the involvement of intermediate peer(s) to perform media post-processing enhancement services is necessary. This mechanism is important and advantageous due to the fact that intermediate post-processing increases the delay and, therefore, should only be employed selectively. FANS considers the size of media data and the capacity of clients bandwidth as network parameters that determine the level of quality of service offered. By employing the above techniques, our experiments with the Internet emulator show that our approach improves the reliability of streaming media applications in such environment
