Changing Patterns of Human Resource Management in Contemporary China: WTO Accession and Enterprise Responses

This study examines the increasingly complex challenges facing human resource management (HRM) in China following the country's accession to the WTO and, consequently, the implications for further reform of government policy and enterprise-level HRM practices. The article concludes that current HR practices among enterprises vary depending on ownership, industrial sector, location and history. The direction of future changes may depend on the level of involvement from external forces as well as internal strategies adopted by Chinese enterprises to survive.
Reception and Measurement of MIMO-OFDM Signals with a Single Receiver

OFDM multi-carrier modulation is expected to be the enabling technology for 4G wireless systems. One of the features that make OFDM the primary choice for 4G is its MIMO compatibility, because MIMO has a very significant potential of enhancing wireless systems for capacity, data rate, and coverage aspects. In this paper, the challenges of MIMO- OFDM measurements are addressed in comparison to SISO, with a special emphasis on WiMAX systems, which employ MIMO- OFDM technology. It is proposed to perform the reception and measurement of MIMO-OFDM signals using a single receiver branch rather than multiple receivers. A complete guide to perform impairment estimation for WiMAX MIMO signals with a single receiver according to the 802.16 standards is also provided.
Receiver windowing for the HomePlug AV system

In this paper we investigate the design of the receiver windowing for the OFDM-based HomePlug AV system, using the OPERA power-line channel models. In particular, the aim of this work is twofold: i) to analyze the anticipation of the demodulation window, based on a new interference free- like condition; ii) to identify the receiver window shape and length, by comparing the performance of some receiver windows under the considered scenarios.

Bioethanol from Lignocellulosic Biomass: Current Findings Determine Research Priorities

“Second generation” bioethanol, with lignocellulose material as feedstock, is a promising alternative for first generation bioethanol. This paper provides an overview of the current status and reveals the bottlenecks that hamper its implementation. The current literature specifies a conversion of biomass to bioethanol of 30 to ~50% only. Novel processes increase the conversion yield to about 92% of the theoretical yield. New combined processes reduce both the number of operational steps and the production of inhibitors. Recent advances in genetically engineered microorganisms are promising for higher alcohol tolerance and conversion efficiency. By combining advanced systems and by intensive additional research to eliminate current bottlenecks, second generation bioethanol could surpass the traditional first generation processes.
Exposing Digital Content as Linked Data, and Linking Them Using StoryBlink

Digital publications host a large amount of data that currently is not harvested, due to its unstructured nature. However, manually annotating these publications is tedious. Current tools that automatically analyze unstructured text are too fine-grained for larger amounts of text such as books. A workable machine-interpretable version of larger bodies of text is thus necessary. In this paper, we suggest a workflow to automatically create and publish a machine-interpretable version of digital publications as linked data via DBpedia Spotlight. Furthermore, we make use of the Everything is Connected Engine on top of this published linked data to link digital publications using a Web application dubbed “StoryBlink”. StoryBlink shows the added value of publishing machineinterpretable content of unstructured digital publications by finding relevant books that are connected to selected classic works. Currently, the time to find a connecting path can be quite long, but this can be overcome by using caching mechanisms, and the relevancy of found paths can be improved by better denoising the DBpedia Spotlight results, or by using alternative disambiguation engines.
SU6668 is a potent antiangiogenic and antitumor agent that induces regression of established tumors.

Vascular endothelial growth factor, fibroblast growth factor (FGF), and platelet-derived growth factor (PDGF) and their cognate receptor tyrosine kinases are strongly implicated in angiogenesis associated with solid tumors. Using rational drug design coupled with traditional screening technologies, we have discovered SU6668, a novel inhibitor of these receptors. Biochemical kinetic studies using isolated Flk-1, FGF receptor 1, and PDGF receptor beta kinases revealed that SU6668 has competitive inhibitory properties with respect to ATP. Cocrystallographic studies of SU6668 in the catalytic domain of FGF receptor 1 substantiated the adenine mimetic properties of its oxindole core. Molecular modeling of SU6668 in the ATP binding pockets of the FIk-1/KDR and PDGF receptor kinases provided insight to explain the relative potency and selectivity of SU6668 for these receptors. In cellular systems, SU6668 inhibited receptor tyrosine phosphorylation and mitogenesis after stimulation of cells by appropriate ligands. Oral or i.p. administration of SU6668 in athymic mice resulted in significant growth inhibition of a diverse panel of human tumor xenografts of glioma, melanoma, lung, colon, ovarian, and epidermoid origin. Furthermore, intravital multifluorescence videomicroscopy of C6 glioma xenografts in the dorsal skinfold chamber model revealed that SU6668 treatment suppressed tumor angiogenesis. Finally, SU6668 treatment induced striking regression of large established human tumor xenografts. Investigations of SU6668 activity in cancer patients are ongoing in Phase I clinical trials.
A Computational Study of the Spreading of Oil Underneath a Sheet of Ice

The spreading of oil underneath a sheet of ice is computed using an adaptive level set method for incompressible two-uid ow. Factors such as viscosity, surface tension, and wall adhesion are taken into account in the computations. The results of the computations agree well with previous experiments and theory. In this work, we also present a v ery eecient and accurate computational method for determining the nal steady proole of a body of oil under ice in water. The computational models are used to make further observations regarding the dependency of the oil spreading radius on the surface energies between the oil, ice, and water.
Set Functionality over DHT Systems

For the last few years, Peer-to-Peer systems were created with the purpose of distributing information across a very large set of hosts. The scalability demands of such systems lead to the design of Distributed Hash Tables algorithms[1, 2, 3, 4], which are capable of locating an object anywhere on the system given a key value using logarithmic (or constant) message hops while maintaining logarithmic state at each host. Nonetheless, DHTs are not able to search for objects but only to retrieve them using keys. Although DHT algorithms locate data objects efficiently, they do not provide any data consistency when using replication. Data replication is made on a “best-effort” way in which data may become inconsistent or even lost. An atomic data access DHT extension which maintained replica consistency using a state machine replication technique was proposed in [5] but required the system to have a stable host membership in order to progress. This requirement is not feasible on wide area systems, like the Internet, where hosts have small uptimes and are under constant churn[6]. Another protocol was proposed in [7] for supporting atomic mutable data in DHTs which is based on the Paxos consensus protocol, but its results have not yet been published. While pursuing efficient search functionality on top of the DHT layer, we implemented a simple set functionality. Our algorithm uses a distributed B-tree to store set data over several hosts. This tree algorithm allows us to perform load-balancing on peers while maintaining logarithmic access to data items. We use any generic DHT algorithm as a simple storage layer, accessing data blocks through a simple key-based routing operation. This operation,route(key,message), is capable of delivering a message to the host responsible for the key using the DHT scalable properties. Our presentation will discuss the issues in implementing a tree-based algorithm over a distributed large-scale key-based routing system. We will also discuss how fault-tolerance (through block replication) influences both data consistency and availability.
The Central American Midsummer Drought: Regional Aspects and Large-Scale Forcing

Abstract The midsummer drought (MSD) is a diminution in rainfall experienced during the middle of the rainy season in southern Mexico and Central America, as well as in the adjacent Caribbean, Gulf of Mexico, and eastern Pacific seas. The aim of this paper is to describe the regional characteristics of the MSD and to propose some possible forcing mechanisms. Satellite and in situ data are used to form a composite of the evolution of a typical MSD, which highlights its coincidence with a low-level anticyclone centered over the Gulf of Mexico and associated easterly flow across Central America. The diurnal cycle of precipitation over the region is reduced in amplitude during midsummer. The MSD is also coincident with heavy precipitation over the Sierra Madre Occidental (part of the North American monsoon). Reanalysis data are used to show that the divergence of the anomalous low-level flow during the MSD is the main factor governing the variations in precipitation. A linear baroclinic model is used to show .

The three-dimensional interaction of a supernova remnant with an interstellar cloud

The hydrodynamic evolution in three dimensions of a spherical bubble embedded in a less dense uniform ambient medium as it interacts with a Mach 10 planar shock is presented. This scenario is an idealized model of the interaction of an interstellar cloud with a large supernova remnant. A third-order Godunov numerical algorithm and 5.2 × 10 6 grid points are used to resolve the complex flow field which results. It is found that the vortex rings observed in two-dimensional simulations are unstable in three dimensions, and the cloud fragments in all directions

Using Cadence Spectre simulation tools to analyze the circuit based on CSMC 0.35um CMOS technology, the results show that the maximum INL (integral nonlinearity) of the DAC is -0.34LSB, the maximum DNL (differential nonlinearity) is -0.18LSB, the power consumption of the whole module is 1.17mW, FoM(Figure of Merit) was 12.3, occupy the chip area is 0.208mm2. This is a good way to meet the requirements of low power consumption and high accuracy of SAR ADC.
Reducing and Balancing Flow Table Entries in Software-Defined Networks

Software-Defined Networking (SDN) allows flexible and efficient management of networks. However, the limited capacity of flow tables in SDN switches hinders the deployment of SDN. In this paper, we propose a novel routing scheme to improve the efficiency of flow tables in SDNs. To efficiently use the routing scheme, we formulate an optimization problem with the objective to maximize the number of flows in the network, constrained by the limited flow table space in SDN switches. The problem is NP-hard, and we propose the K Similar Greedy Tree (KSGT) algorithm to solve it. We evaluate the performance of KSGT against "traditional" SDN solutions with real-world topologies and traffic. The results show that, compared to the existing solutions, KSGT can reduce about 60% of flow entries when processing the same amount of flows, and improve about 25% of the successful installation and forwarding flows under the same flow table space.
International Journal of Physical Sciences Privacy Preserving Data Publishing: Review

Privacy preserving data publishing (PPDP) methods a new class of privacy preserving data mining (PPDM) technology, has been developed by the research community working on security and knowledge discovery. It is common to share data between two organizations in many application areas. When data are to be shared between parties, there could be some sensitive patterns which should not be disclosed to the other parties. These methods aims to keep the underlying data useful based on privacy preservation " utility based method based on privacy preservation, and created tremendous opportunities for knowledge-and information-based decision making. Recently, PPDP has received considerable attention in research communities, and many approaches have been proposed for different data publishing scenarios. In this survey, we will systematically summarize and evaluate different approaches to PPDP, study the challenges in practical data publishing, clarify the differences and requirements that distinguish PPDP from other related problems, and propose future research directions.
The eukaryotic signal sequence, YGRL, targets the chlamydial inclusion

Understanding how host proteins are targeted to pathogen-specified organelles, like the chlamydial inclusion, is fundamentally important to understanding the biogenesis of these unique subcellular compartments and how they maintain autonomy within the cell. Syntaxin 6, which localizes to the chlamydial inclusion, contains an YGRL signal sequence. The YGRL functions to return syntaxin 6 to the trans-Golgi from the plasma membrane, and deletion of the YGRL signal sequence from syntaxin 6 also prevents the protein from localizing to the chlamydial inclusion. YGRL is one of three YXXL (YGRL, YQRL, and YKGL) signal sequences which target proteins to the trans-Golgi. We designed various constructs of eukaryotic proteins to test the specificity and propensity of YXXL sequences to target the inclusion. The YGRL signal sequence redirects proteins (e.g., Tgn38, furin, syntaxin 4) that normally do not localize to the chlamydial inclusion. Further, the requirement of the YGRL signal sequence for syntaxin 6 localization to inclusions formed by different species of Chlamydia is conserved. These data indicate that there is an inherent property of the chlamydial inclusion, which allows it to recognize the YGRL signal sequence. To examine whether this “inherent property” was protein or lipid in nature, we asked if deletion of the YGRL signal sequence from syntaxin 6 altered the ability of the protein to interact with proteins or lipids. Deletion or alteration of the YGRL from syntaxin 6 does not appreciably impact syntaxin 6-protein interactions, but does decrease syntaxin 6-lipid interactions. Intriguingly, data also demonstrate that YKGL or YQRL can successfully substitute for YGRL in localization of syntaxin 6 to the chlamydial inclusion. Importantly and for the first time, we are establishing that a eukaryotic signal sequence targets the chlamydial inclusion.
Differential Drive Wheeled Mobile Robot (WMR) Control Using Fuzzy Logic Techniques

Wheeled Mobile Robot (WMR) is extremely important for active target tracking control and the reactive obstacle avoidance in an unstructured environment. Fuzzy control provides a mechanism for incorporating human-like reasoning capabilities and computationally in control systems. In this paper, a new type of controller based on Fuzzy Logic for differential drive WMR is proposed. The paper begins with design of the WMR which involves the kinematics model and fuzzy controller. Then, simulation and research findings are provided in detail. It was found that the Fuzzy Logic Controller with five membership functions provides better performance compared to that of a seven membership function controller.
Detecting Network Topology and Packet Trajectory with SDN-enabled FPGA Platform

Software-defined networking brings extra complexity to debugging while enhancing network manageability. The competition between applications and subtle bugs in controllers or switches may cause inconformity between control plane logic and data plane behavior. Tracing packet trajectory through the network is a direct way to verify whether data plane processes packets correctly according to control plane policy. We introduce NetMagic, a SDN-enabled switch based on FPGA which can be managed remotely using a custom protocol, and present the detection of network topology and packet trajectory in the network consists of NetMagics. We use probe packet to reproduce the trajectory of arbitrary production packet only by adding three rules per NetMagic to record path history in on-board RAM. The core idea is that we install a hash function both in the controller and NetMagic to process the header of probe packets which considerably reduce the usage of RAM space and facilitate the collection of trajectory data. The evaluation shows that our implementation works properly under high concurrency of tracing tasks by adjusting the parameter of hash function.

PROBING STRIATAL FUNCTION IN OBSESSIVE COMPULSIVE DISORDER Neuroimaging studies of implicit sequence learning

1. IN1RODUCTION Our research team has sought to develop neuroimaging probes of striatal function, to investigate the pathophysiology of obsessive compulsive disorder (OCD) and related diseases. Functional neuroimaging studies have indicated reliable striatal recruitment during a variety of implicit sequence learning and procedural learning tasks. A series of experiments involving the serial reaction time task (SRT) - an implicit sequence learning paradigm - will be reviewed. Experiments employing positron emission tomography (PET) as well as functional magnetic resonance imaging (fMRI) have demonstrated striatal activation associated with implicit learning during the SRT. Moreover, a modified version of the SRT was used to explore temporal aspects of thalamic activity associated with striatal recruitment. Finally, initial findings in OCD and Tourette syndrome will also be discussed.
Guidelines for Science: Evidence and Checklists

Problem: The scientific method is unrivalled as a basis for generating useful knowledge, yet research papers published in management, economics, and other social sciences fields often ignore scientific principles. What, then, can be done to increase the publication of useful scientific papers? Methods: Evidence on researchers’ compliance with scientific principles was examined. Guidelines aimed at reducing violations were then derived from established definitions of the scientific method. Findings: Violations of the principles of science are encouraged by: (a) funding for advocacy research; (b) regulations that limit what research is permitted, how it must be designed, and what must be reported; (c) political suppression of scientists’ speech; (d) universities’ use of invalid criteria to evaluate research — such as grant money and counting of publications without regard to usefulness; (e) journals’ use of invalid criteria for deciding which papers to publish — such as the use of statistical significance tests. Solutions: We created a checklist of 24 evidence-based operational guidelines to help researchers comply with scientific principles (valid inputs). Based on the definition of science, we then developed a checklist of seven criteria to evaluate whether a research paper provides useful scientific findings (valuable outputs). That checklist can be used by researchers, funders, courts, legislators, regulators, employers, reviewers, and journals. Originality: This paper provides the first comprehensive evidence-based checklists of operational guidelines for conducting scientific research and for evaluating the scientific quality and usefulness of research efforts. Usefulness: Journals could increase the publication of useful papers by including a section committed to publishing all relevant and useful papers that comply with science. By using the Criteria for Useful Science checklist, those who support science could more effectively evaluate the contributions of scientists.
