We provide an overview of and key insights into HRM in five Asian countries, representing five key regions: China (East Asia), India (South Asia), Kazakhstan (Central Asia), United Arab Emirates (West Asia), and Vietnam (Southeast Asia). Based on our comprehensive, pan-Asian review, we develop a reflective, comparative, and relational understanding of HRM practices. In doing so, we group the myriad contextual influences on the shaping of HRM practices at three broad levels: macro-, meso-, and microlevel influences. Specifically, we propose that influences from regionalization of economies, national business systems, industry, multinational enterprises, and individual-level predispositions collectively shape and variously influence the nature and extent of HRM practices. By considering the findings of prior research on convergence and divergence, we offer a...

In Vietnam, information on the genetic diversity and population structure of this species, which is necessary for resource management, is limited. In order to address this paucity of information, sequencing of the entire mitochondrial control region (mtDNA) was carried out for 176 individuals collected from central Vietnam. The sequences were investigated using various genetic, phylogenetic and population analyses. A total of 165 distinct haplotypes were identified. The percentage of variation within and among populations was 99.26% and 0.74%, respectively. The fixation index was low (0.007) and not significant (p = 0.096). Therefore, panmixia and a lack of significant population genetic structuring seem likely for A. marmorata in central Vietnam. Most sampled eels were genetically similar to eels found in North Pacific populations (J...

A critical challenge when applying the SVR model is to determine the model for optimal hyperparameters, which can be solved using several optimization methods as the grid search algorithm. Another challenge that affects the response time and the precision of the SVR model is the normalization process of input data. In this paper, the grid search algorithm will be suggested based on data normalization methods including Z-score, min-max, max, decimal, sigmoidal, softmax; and then utilized to evaluate both the response time and precision. To verify the proposed methods, the actual electricity load demand data of two cities, including Queensland of Australia and Ho Chi Minh City of Vietnam, were utilized in this study.

This research aims to address the importance of trust in m-payment adoption, and overcome the limitations of previous studies which are a lack of understanding of the determinants of trust in m-payment adoption, a lack of adopting trust as a multi-dimensional construct, and a lack of consideration of the moderating role of culture. In this research, the authors employ the Unified Theory of Acceptance and Use of Technology, Siau and Shen's framework for building consumer trust in mobile commerce, and Hofstede's cultural framework as the theoretical basis. The proposed model encompasses four types of trust including mobile payment provider trust, mobile technology trust, institution-based trust, and seller trust, which are well-defined in the related literature, and a moderating role for culture between the four types of trust and mobile payment adoption. The model of the study not only may be used to improve understanding of trust in mobile payment adoption, but also contribute to the literature of the determinants for trust in mobile payment adoption.

They are (1) lacking pedagogical theories developed specifically in IS training context, therefore, lacking appropriate pedagogical theory-based training approaches; (2) ineffectiveness of InfoSec training delivery methods due to unengaging, non-authentic security risks and training activities; and (3) and lacking an effective way of measuring effectiveness of InfoSec training. The paper proposes employing design theory as the theoretical basis for InfoSec training, and gamification as the main training and testing method to overcome these gaps. We argue that the design theory for InfoSec training associated with gamification can improve learning results for training and effectiveness testing through providing a joyful, realistic and interactive training. An action research is proposed to further evaluate the effectiveness of the approach.

Escherichia coli strains (ndk) lacking this enzyme have been shown to be modest base substitution mutators, and two members of the human family of NDP kinases act as tumor suppressors. We show here that in E. coli strains lacking NDP kinase high levels of mispairs are generated, but most of these are corrected by the mismatch-repair system. Double mutants that are ndk mutS, lacking both the NDP kinase and mismatch repair, have levels of base substitutions 15-fold higher and levels of certain frameshifts up to 10-fold higher than those of the respective mutations in mutS strains that are NDP kinase proficient. A sequence analysis of the specificity of base substitution mutations generated in ndk and ndk mutS backgrounds as well as other experiments suggests that NDP kinase deficiency stimulates polymerase errors that lead to A:T → G:C transitions and that the editing capacity of cells may be ...

The proposed MEMS variable capacitor is composed of two cross movable electrodes and one dielectric layer between them. The fabrication process does not require any complex processes, such as wafer transfer, wafer backside etching, special planarization or supercritical point drying. The capacitor has tuning range of 330% at 5 V bias voltage, and an overall quality factor of 52 at 2 pF and 2.4 GHz.

Su ámbito de aplicación se relaciona con la geología en particular, por ejemplo como la medida de las deformaciones sísmicas tales como de los volcanes. Últimamente, los investigadores han encontrado que se podía mejorar la comprensión de un deslizamiento a través del uso de estos métodos satelitales. Para ilustrar estos métodos nos centraremos en el Valle de Tena en España. Esta zona localizada en los Pirineos tiene muchas ventajas : i) una gran cantidad y variedad de deslizamientos (cayadas de bloque, deslizamientos, etc...) y ii) una alta apuesta económica (fuerte industria turística con el esquí y una única carretera para el comercio regional y el turismo). Los resultados obtenidos muestran que los datos RADAR TerraSARX revelan puntos estables con una muy buena precisión (milimétrica) en zonas con vegetación baja cubiertas de nume...

The correlation between the hierarchical mesoscopic structures and the mechanical properties of silk soft fibrous materials including silk fibroin hydrogels and naturally spun silk fibers are addressed based on the hierarchical crystal network models. Namely, two types of hierarchical networks are identified: the weak nanofibril-nanofibril interaction case (i.e., silk fibroin hydrogels), and the strong nanofibril-nanofibril interaction case (i.e., silk fibers). The macroscopic properties, i.e., the rheological/mechanical properties, can be controlled in terms of tuning different levels of hierarchical network structures by ultrasonication-induced gelation, introducing the initial nucleation centers, etc. Such controls take effect by different mesoscale assembly...

Although overlay construction is important for system performance, not much effort has been spent on unstructured overlay construction for layered peer-to-peer streaming. Related work concentrates on layered streaming algorithms, and assumes that a list of peers for data exchange, called neighbors, is provided by traditional membership management protocols, e.g., SCAMP. Our previous studies have demonstrated that a random overlay is not good enough for layered peer-to-peer streaming. In this paper, we propose a new membership management protocol, based on peer sampling services. The protocol is quality-aware as it constructs the overlay so that (1) high capacity peers will be located at good positions in the overlay, e.g., close to the server, and (2) peers having similar capacity are likely to connect to each other. Both features are necessary to maximize bandwidth utilization of peers and to mitigate layer bottlenecks. With implementation of the protocol in PeerSim, we evaluate important graph properties of the overlay, constructed by the proposed protocol, to understand how it evolves during the streaming session with peer churn. Evaluation results show that the overlay is (1) scalable: it is stable with different sizes, from hundreds up to 10000 peers; and (2) robust: the good features are maintained or recovered fast under a high peer churn rate, and it only becomes disconnected when more than 86% of the peers are removed from the network.

The n-gram model is shown to have good predictability in supporting code suggestion and completion. However, the state-of-the-art n-gram approach to capture source code regularities/patterns is based only on the lexical information in a local context of the code units. To improve predictability, we introduce SLAMC, a novel statistical semantic language model for source code. It incorporates semantic information into code tokens and models the regularities/patterns of such semantic annotations, called sememes, rather than their lexemes. It combines the local context in semantic n-grams with the global technical concerns/functionality into an n-gram topic model, together with pairwise associations of program elements. Based on SLAMC, we developed a new code suggestion method, which is empirically evaluated on several projects to have relatively 18-68% higher accuracy than the state-of-the-art approach.

When library components evolve to accommodate new feature requests, to fix bugs, or to meet new standards, the clients of software libraries often need to make corresponding changes to correctly use the updated libraries. Existing API usage adaptation techniques support simple adaptation such as replacing the target of calls to a deprecated API, however, cannot handle complex adaptations such as creating a new object to be passed to a different API method, or adding an exception handling logic that surrounds the updated API method calls. This paper presents LIBSYNC that guides developers in adapting API usage code by learning complex API usage adaptation patterns from other clients that already migrated to a new library version (and also from the API usages within the library's test code). LIBSYNC uses several graph-based techniques (1) to identify changes to API decla...

Rod influence was taken as the difference in error scores obtained after complete dark adaptation and during the cone plateau at three mesopic (23, 9, 3 td) and one standard (158 td) light level. On the FM 100, rods produced a differential discrimination loss along a tritan axis as compared with a red-green axis without any bias toward a rod confusion axis. Rods appear to impair discrimination mediated by Scone pathways, which at moderate levels of illumination can differentially elevate tritan errors on the FM 100.
