Linshuichonetes gen. nov., a new rugosochonetid (Brachiopoda) genus from the Liangshan Formation (Early Permian) in Sichuan, China, and its ecology

A new genus and species, Linshuichonetes elfinis, belonging to the Rugosochonetidae, is described from the Early Permian (Late Artinskian or early Kungurian) Liangshan Formation of the Yangtze block. The new genus is defined externally by the presence of fine, but delayed, capillation and a weak or absent median sulcus and fold and by the presence of a distinct posteromedian sinus on the ventral umbo; and internally by a lack of median, lateral and accessory septa in the dorsal interior; absence of vascular trunks in the ventral interior and the presence of distinct radiating rows of papillae in the interior of both valves, particularly an unusual clustered arrangement of papillae on the posteromedian portion of the dorsal interior. The local environment during the deposition of the Liangshan Formation appears to have been a restricted tidal flat or lagoon which experienced frequent sealevel fluctuations associated with the onset of the Yanghsingian transgression. The new species, L. elfinis, appears to have several morphological adaptations enabling successful exploitation of this environment. It was typically a very small and thin-valved species with a high surface area to volume ratio, an advantage in an oxygen restricted environment. The small size and numerous body spinules would have aided individuals to remain suspended at the top of the fine, soft substrate. It also dominated the brachiopod assemblage in the Liangshan Formation, comprising up to 94%of specimens within a bed. These factors indicate that the new species appears to be an opportunistic species.

Gen Zeds: Arab women speaking with “still small voices”

The “Gen Zeds” of the title are female Emirati students in their early twenties at Zayed University who oscillate between the traditional Islamic culture of their families, and the highly mediated global culture they experience at university and on the Internet. In a typical week these women spend as much time on the Internet as they do in the combined activities of reading magazines, newspapers and books. They spend twice as much time on the Internet as they do watching television.

Media life among gen zeds

The ‘Gen Zeds’ of the title are female Emirati students in their early 20s at Zayed University who oscillate between the traditional Islamic culture of their families and the high technology world they experience through the media. This article looks at when, where and how these students use media and what they are looking for when they use it. The research found that these women live a highly-mediated existence, spending more than 9.9 hours on average a day with the media - more time than they do sleeping. They spend as much time on the internet as they do in the combined activities of reading magazines, newspapers and books. They spend twice as much time on the internet as they do watching television. They use different media during different parts of the day and for different reasons. The internet and the telephone were the two most preferred media. The article concludes by looking at what these women’s highly mediated lives might mean for their future.

Gen zeds : Arab women speaking with 'still small voices'

The ‘Gen Zeds’ are female Emirati students in their early twenties at Zayed University who oscillate between the traditional Islamic culture of their families, and the highly mediated global culture they experience at university and on the Inter-net. These students come almost entirely from prosperous families. On graduation, they are expected to assume leadership positions in the United Arab Emirates – a country in transition – despite living in a society that recently has not permitted women roles beyond that of mother and homemaker. This article considers whether the lessons and experiences they encounter at university – and their intense exposure to a technology-mediated world – will equip them for life in a society radically different from that of their mothers, and whether their ‘still small voices’ will be heard in a new technology economy.

Review of Alataleberis McKenzie and Warne, 1986 and description of Alatapacifica gen. nov. (Ostracoda, Crustacea) from the Cenozoic of Australasia

Species originally assigned to the pterygocytherine genus Alataleberis by McKenzie & Warne, 1986 are placed here in two genera—Alataleberis sensu stricto and Alatapacifica gen. nov. Alataleberis species possess poorly defined dorsal ridges marked by a few spines in adult specimens and lack a subcentral tubercle. Alatapacifica species possess well-developed and buttressed dorsal ridges and a well-developed subcentral tubercle. Pterygocytherine genera/species groups recognized here from the southwest Pacific region are Alataleberis, Alatapacifica (septarca and robusta species groups), Alatahermanites Whatley & Titterton, 1981 and the velivola species group of Pterygocythereis Blake, 1933.

Gen Y and their 'backpacks of hidden treasures'

This paper reports on part of a teacher/researcher’s PhD action research study conducted in an Australian public high school, investigating the use of online social networking as a classroom learning environment where students were encouraged to find and use their hidden treasures. It examines student reactions and online activity whilst they are interacting with a range of Web 2.0 and social media tools. The study may inform the rising generation of higher education learners and their course developers and explores the move from passive to active learning through Gen Y’s engagement with online social media. It looks at a range of innovative practices that were made possible through using a Ning online social network as a classroom environment whilst encouraging Gen Y to take more responsibility for learning. It also looks at the pedagogical implications that come with the use of social media as they challenge traditional models of ‘instructional order’. This study primarily adopts a social constructivist approach to teaching with the focus being on learning, rather than teaching. The study found that having such a flexible curriculum environment encouraged Gen Y to share their ‘hidden treasures’ and, hence, informal classroom learning became more visible and more readily documented. Gen Y students appreciated the opportunities to publish and to gain feedback from more than their teacher alone. Students, in some cases, could be seen to be engaged in their own cycle of learning where they valued the opinion of their peers which, in turn, helped them to improve their work.

Description of systenobythere gen. nov. (Ostracoda, Crustacea) from the late miocene of southeastern Australia with comments on its problematical taxonomic and palaeoecological affinities

A new ostracod genus and species, Systenobythere archboldi, is described from late Miocene open neritic strata of southeastern Australia. Specimens occur in argillaceous glauconitic sands deposited in offshore continental shelf settings that were periodically influenced by coastal upwelling. Systenobythere archboldi possesses an adductor muscle scar pattern typical of the Bythocytheridae, but has a pentodont hinge and sieve-type normal pore canals atypical of this family.

A serverless ultra-lightweight secure search protocol for EPC Class-1 Gen-2 UHF RFID tags

Radio Frequency Identification (RFID) is a technology that enables the non-contact, automatic and unique identification of objects using radio waves. Its use for commercial applications has recently become attractive with RFID technology seen as the replacement for the optical barcode system that is currently in widespread use. RFID has many advantages over the traditional barcode and these advantages have the potential to significantly increase the efficiency of decentralised business environments such as logistics and supply chain management. One of the important features of an RFID system is its ability to search for a particular tag among a group of tags. In order to ensure the privacy and security of the tags, the search has to be conducted in a secure fashion. To our knowledge not much work has been done in this secure search area of RFID. The limited work that has been done does not comply with the EPC Class-1 Gen-2 standards since most of them use expensive hash operations or sophisticated encryption schemes that cannot be implemented on low-cost passive tags that are highly resource constrained. Our work aims to fill this gap by proposing a serverless ultra-lightweight secure search protocol that does not use the expensive hash functions or any complex encryption schemes but achieves compliance with EPC Class-1 Gen-2 standards while meeting the required security requirements. Our protocol is based on XOR encryption and random numbers - operations that are easily implemented on low-cost RFID tags. Our protocol also provides additional protection using a blind-factor to prevent tracking attacks. Since our protocol is EPC Class-1 Gen-2 compliant it makes it possible to implement it on low-cost passive RFID tags.

A secure search protocol based on Quadratic Residues for EPC Class-1 Gen-2 UHF RFID tags

Radio Frequency Identification (RFID) is a technological revolution that is expected to soon replace barcode systems. One of the important features of an RFID system is its ability to search for a particular tag among a group of tags. This task is quite common where RFID systems play a vital role. To our knowledge not much work has been done in this secure search area of RFID. Also, most of the existing work do not comply with the C1G2 standards. Our work aims to fill that gap by proposing a protocol based on Quadratic Residues property that does not use the expensive hash functions or any complex encryption schemes but achieves total compliance with industry standards while meeting the security requirements.
