Graphettes: Constant-time determination of graphlet and orbit identity including (possibly disconnected) graphlets up to size 8.

Graphlets are small connected induced subgraphs of a larger graph G. Graphlets are now commonly used to quantify local and global topology of networks in the field. Methods exist to exhaustively enumerate all graphlets (and their orbits) in large networks as efficiently as possible using orbit counting equations. However, the number of graphlets in G is exponential in both the number of nodes and edges in G. Enumerating them all is already unacceptably expensive on existing large networks, and the problem will only get worse as networks continue to grow in size and density. Here we introduce an efficient method designed to aid statistical sampling of graphlets up to size k = 8 from a large network. We define graphettes as the generalization of graphlets allowing for disconnected graphlets. Given a particular (undirected) graphette g, we introduce the idea of the canonical graphette [Formula: see text] as a representative member of the isomorphism group Iso(g) of g. We compute the mapping [Formula: see text], in the form of a lookup table, from all 2k(k - 1)/2 undirected graphettes g of size k ≤ 8 to their canonical representatives [Formula: see text], as well as the permutation that transforms g to [Formula: see text]. We also compute all automorphism orbits for each canonical graphette. Thus, given any k ≤ 8 nodes in a graph G, we can in constant time infer which graphette it is, as well as which orbit each of the k nodes belongs to. Sampling a large number N of such k-sets of nodes provides an approximation of both the distribution of graphlets and orbits across G, and the orbit degree vector at each node

2Drivers and Moderators of Consumer Behaviour in the Multiple Use of Mobile Phone

The emergence of m-commerce and mobile data service (MDS) attract much of the attentions in the field of m-business. Salient studies have mainly identified the critical factors that drive consumer intentions to adopt a new mobile technology or a cluster of mobile services. While various technologies and services are embedded into one consumer device, existing models have limitations in explicating how consumers respond to the phenomenon of convergent technologies and services and cannot be used to understand consumer usage or future demand. Therefore, this research aims at not only expanding the research contexts from m-commerce but also encompasses the uses of convergent technologies and services on mobile phones. An empirical model is verified through a survey of 249 general mobile phone users in Australia. Findings indicate that perceived enjoyment rather than perceived usefulness and ease of use has a greater impact on consumers’ decisions to use mobile phones for personal information management, entertainment and e-mail communication. Perceived risk is the major consideration for consumers using mobile phones for commercial transactions. Gender and PC ownership are identified as two important factors that moderate the mobile phone use for the four different purposes. The findings are expected to contribute to the understanding of using convergent technologies and services from a consumer perspective

Understanding Consumers’ Behaviour when Using a Mobile Phone as a Converged Device

This research develops an empirical model to explore the factors that influence consumers’ behaviour while using a mobile phone as a converged device, i.e., using different functions and services on a mobile phone for multiple purposes. Convergence in this domain is particularly regarded as a social phenomenon that has now existed for over two decades. However, empirical research is lacking in terms of individual’s perception and behaviour toward using a converged device. This research is the first to provide an exploratory study of individual uses of a mobile phone for personal information management (PIM), e-mail, entertainment, and commercial transaction. It also draws from the Technology Acceptance Model (TAM) and identifies some of the antecedent factors that influence the above behaviours and behavioural intentions. Fifty mobile phone users were interviewed and provided their thoughts and experiences of using a mobile phone other than voice communication. The interview data was transcribed and analysed to develop an empirical model. The finding shows that although the TAM has been effective in explaining behaviours in the context of single-functional technologies, it needs further enrichment when applying it to multi-function (converged) technologies. Therefore, the result provides a significant step towards a better understanding of consumer behaviour and creates a better strategy for the market of technology convergence in the future

A Study on Taiwan Consumers’ Adoption of Online Financial Services

Despite Taiwan financial institutions’ huge investments in online financial services systems, Taiwan consumers’ adoption of online financial services has been slower than anticipated. So far, online financial services research in Taiwan is still in its infancy, hence receiving little academic attention. This suggests a need to understand Taiwan Internet users’ adoption behavior of online financial services and to identify the potential factors that may motivate or impede Taiwan Internet users’ acceptance of online financial services. The research framework of this study is constituted by the extended version of the Technology Acceptance Model (TAM2). Other variables, which have proven academically important in influencing consumers’ intentions to use information technology, were added to the conceptual framework. The results strongly support that the extended TAM (TAM2) is a valid model to predict Taiwan consumers’ intention to use online financial services and to explain the intention difference between adopters and non-adopters. The results also demonstrated that perceived privacy protection, perceived security, and consumer innovativeness not only have a significant, positive relationship with Taiwan consumers’ intention to use online financial services but also can significantly predict who is more likely to be an online financial service adopter in Taiwan. The research findings may help Taiwan financial institutions and other interested parties to formulate appropriate marketing strategies and design effective online financial services systems and accelerate the diffusion of online financial services in the future

Back-end of line compatible transistors for hybrid CMOS applications

The low-temperature back-end of line (BEOL) compatible transparent amorphous oxide semiconductor (TAOS) TFTs and poly-Si TFTs are the suitable platforms for three-dimensional (3D) integration hybrid CMOS technologies. The n-channel amorphous indium tungsten oxide (a-IWO) ultra-thin-film transistors (UTFTs) have been successfully fabricated and demonstrated in the category of indium oxide based thin film transistors (TFTs). We have scaled down thickness of a-IWO channel to 4nm. The proposed a-IWO UTFTs with low operation voltages exhibit good electrical characteristics: near ideal subthreshold swing (S.S.) ~ 63mV/dec., high field-effect mobility (FE) ~ 25.3 cm2/V-s. In addition, we also have fabricated the novel less metal contamination Ni-induced lateral crystallization (LC-NILC) p-channel poly-Si TFTs. The matched electrical characteristics of n-channel and p-channel devices with low operation voltage and low IOFF are exhibiting the promising candidate for future hybrid CMOS applications

Dynamic Power Index Adjustment Based On Battery Level

This disclosure describes techniques for dynamic adjustment of output power index of a wireless remote controller device based on a detected battery level of the device. The battery voltage level of the device is periodically measured. When the level falls below a predetermined threshold, the output power index is adjusted to ensure that the total transmit power from the controller device lies within a specified range. Dynamic adjustment of transmit power via the power index adjustment enables the controller device to have a transmit power that lies between the power spectral distribution (PSD) target and the PSD limit (maximum) over a range of battery voltage values

Does compensative subsidy alleviate pollutant emission and improve welfare under crossindustry pollution?

This paper establishes a cross-industry pollution externality model under centralized labor union. In delineating the motivations of a benevolent government, it might be possible to tax part of the welfare gains and use the revenue to compensate the affected polluting industry for the damage costs, thereby improving welfare. We show that the magnitude of marginal pollution plays a critical role. When the marginal pollution is large, the government should tax the pollution firm to reduce the pollution. However, when the marginal pollution is small, the government should subsidize the polluted firm to increase output and enhance consumer surplus

THE EFFECTS OF KINESIO TAPING ON RATE OF FORCE DEVELOPMENT IN SQUAT JUMP AND COUNTER MOVEMENT JUMP

Kinesio tape (KT) has been widely used to prevent muscle pain and to improve strength and sports performance. Therefore, the aim of this study was to investigate the effect of KT in rate of force development (RFD). To compare with KT or non-KT in squat jump (SJ) and counter movement jump (CMJ). The RFD was improved or not improved by using KT. Six healthy female was recruited in this study. The kistler force plate was used to measure the RFD. There is no significant improve in SJ and CMJ. The results showed that KT did not affect RFD
