Request mitigating devices in Australian English and Iraqi Arabic : a comparative study

Significant issues, especially miscommunication in a cross-cultural setting and pragmatic failure in second language (L2) acquisition, stem from the linguistic and cultural differences between social groups. The investigation of speech acts realization in everyday situations is deemed as an important field to explore the impact of linguistic and cultural variations on cross-cultural communication and L2 acquisition. This paper examines the internal and external mitigating devices that Australian English native speakers (AENSs) and Iraqi Arabic native speakers (IANSs) use to soften the force of request speech acts in everyday situations. It aims to explore request mitigating devices employed in Australian English and Iraqi Arabic in terms of semantic formulae and frequencies in everyday interaction. Request samples were collected from native speakers of Australian English and Iraqi Arabic by means of role-play interviews. The mitigating devices found in requests were identified and classified. The results showed that internal mitigating devices were more frequent in AENSs’ requests than in IANSs’ requests, while external mitigating devices were pervasive in both groups. The two groups also used different semantic formulae of some mitigating devices in some situations. The pervasive occurrence of external mitigators in both groups’ requests is explained in terms of the notion of volubility as a politeness strategy. It is also suggested that the divergence between the two groups in their utilization of request mitigations is related to linguistic and cultural variations between the Australian and Iraqi cultures.

Comparative study on MoO3 and HxMoO3 nanobelts : structure and electric transport

In this study, the suspension of MoO3 nanobelts was first prepared in a hydrothermal way from Mo powders and H2O2 solution, which could be transformed into the suspension of HxMoO3 nanobelts under an acidic condition using N2H4 ·H2O as the reducing agent. Three paper-form samples made from MoO3 and HxMoO3 nanobelts (low or high hydrogen content) were then fabricated via a vacuum filtration method, followed by their structural comparative analysis such as FESEM, XRD, Raman spectra, and XPS, etc. The measurement of electric resistances at room temperature shows that the conductance of HxMoO3 nanobelts is greatly improved because of hydrogen doping. The temperature-dependent resistances of HxMoO3 nanobelts agree with the exponential correlation, supporting that the conducting carriers are the quasi-free electrons released from Mo5+. In addition, the formation process of HxMoO3 nanobelts from MoO3 nanobelts is also discussed.

Critical analysis and comparative study of security for networked RFID systems

The Radio frequency identification (RFID) system is a new technology which uses the open air to transmit information. RFID technology is one of the most promising technologies in the field of ubiquitous computing which is revolutionizing the supply chain. It has already been applied by many major retail chains such as Target, Wal-Mart, etc. The networked RFID system such as supply chain has very unique and special business needs which lead to special sets of RFID security requirements and security models. However, very little work has been done to analyze RFID security parameters in relation to networked RFID systems business needs. This paper presents a critical analysis of the networked application's security requirements in relation to their business needs. It then presents a comparative study of existing literature and the ability of various models to protect the security of the supply chain in a RFID deployment.

In search of best practices in responsible gambling ( RG ) : a report on a comparative study of RG among Macau, Las Vegas, and Melbourne, presented to the MSAR Bureau of Gaming Inspection and Coordination (DICJ).

This is a project sponsored by the Asia Pacific Association for Gambling Studies (APAGS) and supported by funds from the MSAR’s Bureau of Gambling Inspection and Coordination (DICJ). The research team comprises as Chief Investigators: Prof. Zhidong Hao of the University of Macau; Prof. Linda Hancock of Deakin University, Australia, and Prof. William Thompson, University of Las Vegas (UNLV). The project research was conducted between the end of December 2012 and July 2013.
The starting point for the research was to select four out of the six casino companies licensed to operate in Macau that also operate transnationally, that is, either in Las Vegas or Melbourne. Hence, the Venetian, Wynn, MGM, and the Melco-Crown Entertainment are the focus of research. The main objectives of the project are to explore how responsible gambling is framed in each of the three jurisdictions (Macau, Las Vegas and Melbourne); how it is approached cross-jurisdictionally by each of the companies; and to assess current approaches within a broader comparative context against international best practice. The research explores Responsible Gambling measures taken by a range of stakeholders including the government/regulators in each of the three jurisdictions, casino managements, problem gambling counselling services, unions and community organizations. The research emphasizes what problems prevail, and the implications of this research for enhancing Responsible Gambling in Macau.

Comparative study of routing protocols for opportunistic networks

Opportunistic networks or OppNets refer to a number of wireless nodes opportunistically communicating with each other in a form of “Store-Carry-Forward”. This occurs when they come into contact with each other without proper network infrastructure. In OppNets there is no end-to-end connection between the source node and the destination node. OppNets grow from a single node (seed) to become large networks by inviting new nodes (helpers) to join the network. Due to these characteristics, OppNets are subject to real routing challenges. In this paper, we have presented an overview of the main available three families of OppNet routing protocols. Further, we have evaluated one protocol from each family (Epidemic, Direct Delivery and PRoPHET) in terms of complexity and scalability. Simulation results show that for small and medium complexity, the three protocols perform better than large complexity. As for scalability, simulation results show that Epidemic and PRoPHET perform better than Direct Delivery in terms of delivery rates and delays, but at a very high cost while Direct Delivery achieved lower delivery rates with a low cost.
