Transfer of HRM practices in French multinational companies: the case of French subsidiaries in China

Abstract: Our research investigates the transfer of home country human resource management (HRM) practices to their overseas subsidiaries. We seek to figure out how three levels of factors (country, organisation and individual) from a host country affect the international transfer process. We identify the effects of culture, institutional interactions, entry modes and expatriates on this transfer. Based on a detailed case study of eight French multinational companies in China, we explain how the transfer of HRM practices is realised. Our empirical findings indicate that French subsidiaries tend to adopt the parent company’s HRM practices to a considerable extent. Instead of focussing on cultural differences, the main contraints to the successful transfer of HRM practices are institutional interactions and entry modes. Additionally, we identify the role of expatriates in the transfer process.
Distinct Molecular Pathways to X4 Tropism for a V3-Truncated Human Immunodeficiency Virus Type 1 Lead to Differential Coreceptor Interactions and Sensitivity to a CXCR4 Antagonist

ABSTRACT During the course of infection, transmitted HIV-1 isolates that initially use CCR5 can acquire the ability to use CXCR4, which is associated with an accelerated progression to AIDS. Although this coreceptor switch is often associated with mutations in the stem of the viral envelope (Env) V3 loop, domains outside V3 can also play a role, and the underlying mechanisms and structural basis for how X4 tropism is acquired remain unknown. In this study we used a V3 truncated R5-tropic Env as a starting point to derive two X4-tropic Envs, termed ΔV3-X4A.c5 and ΔV3-X4B.c7, which took distinct molecular pathways for this change. The ΔV3-X4A.c5 Env clone acquired a 7-amino-acid insertion in V3 that included three positively charged residues, reestablishing an interaction with the CXCR4 extracellular loops (ECLs) and rendering it highly susceptible to the CXCR4 antagonist AMD3100. In contrast, the ΔV3-X4B.c7 Env maintained the V3 truncation but acquired mutations outside V3 that were critical for X4 tropism. In contrast to ΔV3-X4A.c5, ΔV3-X4B.c7 showed increased dependence on the CXCR4 N terminus (NT) and was completely resistant to AMD3100. These results indicate that HIV-1 X4 coreceptor switching can involve (i) V3 loop mutations that establish interactions with the CXCR4 ECLs, and/or (ii) mutations outside V3 that enhance interactions with the CXCR4 NT. The cooperative contributions of CXCR4 NT and ECL interactions with gp120 in acquiring X4 tropism likely impart flexibility on pathways for viral evolution and suggest novel approaches to isolate these interactions for drug discovery.
Research on the design of fire decision making knowledge base

To solve the lacking of concept reusing and information sharing problems in fire dispatching decision knowledgebase system, a domain ontology based fire knowledge base model is presented. Fire commanding ontology (FCO) was created to represent domain concepts and the relationship between concepts. FCO was used to construct the semantic description database of information resource in fire dispatching system. The fire domain ontology modeling is discussed. Based on current ontology represent languages, fire commanding ontology represent language (FCORL) is presented. An ontology-based fire decision-making knowledgebase prototype system is constructed. The simulation results show that the model implements concept is reusing and information sharing. At the same time, it improve the level of real-time, accuracy and reliability of the system.
Adoption and use of information and communication technologies by Pentecostal churches in Ibadan, Nigeria

Information and communication technologies have been accepted as one of the most significant forces of modernization. Studies have looked at the role information and communication technologies play in religion and their application in religious environments. However, the majority of these studies focused on the developed world. Few empirical studies focused on Nigeria. This study investigated the adoption and use of information and communication technologies by Pentecostal churches in Ibadan, Nigeria. The results revealed that the majority of Pentecostal churches in Ibadan have adopted and are using information and communication technologies, the main reason being to propagate the gospel. This research has been able to contribute to knowledge by bringing out their role and impact on church growth, spiritual upliftment of members and its concomitant effect on society as a whole.
Product Quality, Consumer Information and "Lemons" in Experimental Markets

This paper reports on the behavior of experimental markets wherein buyers were ignorant (unless truthfully informed by sellers) of the quality of the product purchased. True quality of the product was learned only after the sale. Sellers chose quality or "grade" and higher quality was more costly to produce. Our experimental markets were characterised by asymmetric information possessed by buyers and sellers who traded a pure "experience" good whose quality was endogenously determined.
New genetic variants in the CCR5 gene and the distribution of known polymorphisms in Omani population

C–C motif chemokine receptor‐5 (CCR5) is a pro‐inflammatory receptor that binds to chemokines and facilitates the entry of the R5 strain of HIV‐1. A number of polymorphisms were identified within the promoter and coding regions of the CCR5 gene, some of which have been found to affect the protein expression and thus receptor function. Although several CCR5 polymorphisms were shown to vary widely in their distribution among different ethnic populations, there has been no study addressing the potential variants of the CCR5 gene in the Omani population. The aim of this study was to identify the polymorphic sites that exist within the CCR5 gene in Omanis. Blood samples were collected from 89 Omani adult individuals, and genomic DNA was amplified by polymerase chain reaction and sequenced to identify the polymorphic sites. The distribution of the detected variants was examined and compared with the previously published data. Four new indels were detected of 32 variable positions, −2973A/–, −2894A/–, −2827TA/– and −2769T/–, and all were located in the 5′UTR. Furthermore, two new mutations, −2248G/A and +658A/G, were observed for the first time; the −2248G/A was detected in the intron 1 region in one subject and +658A/G in the coding region of the CCR5 in another subject. In silico analysis showed that the novel variations in the 5′UTR may have effects on the transcription factor binding sites. Therefore, this study demonstrates the presence of two new SNPs and four novel indels in the CCR5 gene in the Omani population. Our findings support the wide spectrum of genetic diversity reported within the CCR5 gene region among different ethnic groups.
A review of detection plagiarism in indonesian language

Plagiarism is the act of copying the work of another person in the form of writing, ideas, creative ideas or other without including the source of the work or idea. This action is of course very disrespectful, violates the code of ethics and is opposed by all parties, both by scientists and the government. This happens because the use of the internet provides unlimited information services. Many studies have been carried out, raising the theme of this plagiarism. This article will review how far the plagiarism research has been done on Indonesian writing. By knowing the development of plagiarism research, further research will have better sustainability.
Design and analysis of UHF tag antenna structure

For passive RFID tags, one of the most important parameter is the read range. The power transferred to the tag IC and the tag read range are maximized when the reactance of the tag and IC chip are conjugate-matched. Structures effecting on antenna performance are studied in this paper that is based on the dipole antenna: Meander-line and tip-loading may reduce the size of UHF tag antenna. Shunt/Series inductors can increase antenna reactance. Large line-widths can improve the bandwidth of antenna.
The development of the human hyoid–larynx complex revisited

The hyoid–larynx complex is highly prone to anatomical variation. The etiology of anatomical variants such as Eagle's syndrome and the aberrant hyoid apparatus can be explained from embryonic development. Modern textbooks state that the hyoid bone body develops from the second and third pharyngeal arch cartilages, and that thyroid cartilage derives from the fourth and sixth arch cartilages. This description, however, is incompatible with various anatomical variants, and it is unclear whether it was based on observations in human embryos or on comparative embryology.

A new model for the resolution of cultural and biological inheritance in the presence of temporal trends: Application to systolic blood pressure

A contemporary path model for the resolution of cultural and biological inheritance is extended to incorporate temporal variation in family resemblance. Specifically, the genetic and environmental effects, like all other parameters of the model, are allowed to vary over an individual's age according to some specific mathematical functions. In the computer program BETREND a library of such functions is incorporated. Data on systolic blood pressure in 542 Japanese‐American nuclear families were analyzed. This new methodology detected significant temporal variation in cultural inheritance, a result that was not found previously by using static models which could only distinguish between adult and childhood heritabilities. Cultural heritability, estimated to be 10% at birth, increases to a maximum of 28% at age 36, at which time it declines until it eventually reaches 10% at age 49. Although not statistically significant, there was some evidence for temporal trends in genetic heritability as well. Ignoring trends, the genetic heritability was estimated as . 30. On the other hand, trends in sibling environment were clearly nonsignificant. This model provides an objective method of testing the significance of temporal trends in familial resemblance by using multifactorial models, of resolving varying gene expression and transient environmental effects as possible sources of generating the observed temporal variation, and of estimating continuous changes in heritability with age.
Dynamic Behavior of the Doubly Fed Induction Generator During Three-Phase Voltage Dips

The use of doubly fed induction generators (DFIGs) in large wind turbines has become quite common over the last few years. These machines provide variable speed and are driven with a power converter which is sized for a small percentage of the turbine-rated power. A drawback of the DFIG is that it is very sensitive to grid disturbances, especially to voltage dips. However, the operation of the machine in these situations has only been studied in the literature by means of simulations. This paper develops a theoretical analysis of the dynamic behavior of the induction machine during three-phase voltage dips. The proposed analysis contributes to understanding the causes of the problem and represents a very useful tool to improve the existing solutions and propose new alternatives. Experimental results are in good agreement with those obtained theoretically and validate the proposed analysis.
Job Flows and the Recent Business Cycle: Not All 'Recoveries' Are Created Equal

The last two economic downturns are notable for their slow labor market recoveries. Yet, the behavior of their underlying gross job flows is quite different. The 1990-92 period had a relatively slow decline in job destruction, while the 2001-03 period had a large, persistent decline in job creation that occurs across most industries. The dynamics of the latter period run counter to the conventional wisdom that large movements in job destruction drive business cycles. Evidence spanning the entire postwar period suggests that job creation is at a historic low, and that its recent patterns are part of decades-long decline in the magnitude and volatility of job reallocation.
New multi-way SIW power dividers with high isolation

In this letter, a new method is proposed to design SIW-based multi-way power dividers utilizing SIW directional couplers. Two examples respectively with equal and unequal power division ratio are given. The simulated and measured results show that the designed power dividers have wide bandwidth and low insertion loss over the whole operating bandwidth. The phase differences between output ports are also compensated. Moreover, the isolations between the output ports have been significantly improved.

fastGCVM: A Fast Algorithm for the Computation of the Discrete Generalized Cramér-von Mises Distance

Comparing two random vectors by calculating a distance measure between the underlying probability density functions is a key ingredient in many applications, especially in the domain of image processing. For this purpose, the recently introduced generalized Cramér-von Mises distance is an interesting choice, since it is well deﬁned even for the multivariate and discrete case. Unfortunately, the naive way of computing this distance, e.g., for two discrete two-dimensional random vectors ˜ x , ˜ y ∈ [ 0 ,. , n − 1 ] 2 , n ∈ N has a computational complexity of O ( n 5 ) that is impractical for most applications. This paper introduces fastGCVM, an algorithm that makes use of the well known concept of summed area tables and that allows to compute the generalized Cramér-von Mises distance with a computational complexity of O ( n 3 ) for the mentioned case. Two experiments demonstrate the achievable speed up and give an example for a practical application employing fastGCVM.
La segmentación mediante clases latentes en el sector de la telefonía móvil: relación entre calidad de servicio, satisfacción y confianza con la intención de recompra

In this paper the relationship that perceived service quality, satisfaction and trust have on the purchase intention is analyzed. Concretely, three latent class segments that imply different behaviours from these relationships in different groups of consumers have been found. The latent class regression analysis and the LC cluster are the statistical tools used in this work. It has been proven that to predict the purchase intention through quality, satisfaction and trust, it is necessary to keep in mind that not for all consumers the variables of the model have the same strength, not even the same sign. For that reason, the identification of those groups of clients is fundamental in order to adapt properly marketing policies.
Protein kinase CK2 and its role in cellular proliferation, development and pathology

Protein kinase CK2 is a pleiotropic, ubiquitous and constitutively active protein kinase that can use both ATP and GTP as phosphoryl donors with specificity for serine/threonine residues in the vicinity of acidic amino acids. Recent results show that the enzyme is involved in transcription, signaling, proliferation and in various steps of development. The tetrameric holoenzyme (α2β2) consists of two catalytic α‐subunits and two regulatory β‐subunits. The structure of the catalytic subunit with the fixed positioning of the activation segment in the active conformation through its own aminoterminal region suggests a regulation at the transcriptional level making a regulation by second messengers unlikely. The high conservation of the catalytic subunit from yeast to man and its role in the tetrameric complex supports this notion. The regulatory β‐subunit has been far less conserved throughout evolution. Furthermore the existence of different CK2β‐related proteins together with the observation of deregulated CK2β levels in tumor cells and the reported association of CK2β protein with key proteins in signal transduction, e.g. A‐Raf, Mos, p90rsk etc. are suggestive for an additional physiological role of CK2β protein beside being the regulatory compound in the tetrameric holoenzyme.
Risk evaluation for deteriorating systems with accuracy analysis of parameter estimation

Risk analysis, which is a useful methodology to evaluate the performance of systems, can provide important information for maintenance decision and ensure stable running of the system. As a score function of the occurrence, severity and detection of a failure, risk priority number is the most common risk analysis approach. For degrading systems, the probability of failure occurrence could be obtained by modeling the degradation path, and the severity of failure could be quantified through engineering experience. Generally, the accuracy of the model is affected by the number of training data reflecting the detection. In this paper, we focus on statistical data driven approaches, which rely on the degradation data and statistical process model to describe the degradation path. First of all, we discuss the relationships between the accuracy of parameter estimation with likelihood function as well as the corresponding information entropy, based on probability theory and information theory. Then relative entropy indicating the distance between two distributions is utilized to evaluate the accuracy of parameter estimation, i.e. the degree of detection. Moreover, the risk value can be derived, because the probability of failure can be evaluated via modeling the degradation path. Finally, a numerical study is provided to illustrate the rationality and advantage of the proposed method over the traditional one.
Persistent currents in multichannel interacting systems.

Persistent currents of disordered multichannel mesoscopic rings of spinless interacting fermions threaded by a magnetic flux are calculated using exact diagonalizations and self-consistent Hartree-Fock methods. The validity of the Hartree-Fock approximation is controled by a direct comparison with the exact results on small $4\times4$ clusters. For sufficiently large disorder (diffusive regime), the effect of repulsive interactions on the current distribution is to slightly decrease its width (mean square current) but to {\it increase} its mean value (mean current). This effect is stronger in the case of a long range repulsion. Our results suggest that the coupling between the chains is essential to understand the large currents observed experimentally.
Clinical value of multidetector CT coronary angiography as a preoperative screening test before non-coronary cardiac surgery

Objective: Myocardial scintigraphy and/or conventional angiography (CA) are often performed before cardiac surgery in an attempt to identify unsuspected coronary artery disease which might result in significant cardiac morbidity and mortality. Multidetector CT coronary angiography (MDCTCA) has a recognised high negative predictive value and may provide a non-invasive alternative in this subset of patients. The aim of this study was to evaluate the clinical value of MDCTCA as a preoperative screening test in candidates for non-coronary cardiac surgery. Methods: 132 patients underwent MDCTCA (Somatom Sensation 16 Cardiac, Siemens) in the assessment of the cardiac risk profile before surgery. Coronary arteries were screened for ⩾50% stenosis. Patients without significant stenosis (Group 1) underwent surgery without any adjunctive screening tests while all patients with coronary lesions ⩾50% at MDCTCA (Group 2) underwent CA. Results: 16 patients (12.1%) were excluded due to poor image quality. 72 patients without significant coronary stenosis at MDCTCA were submitted to surgery. 30 out of 36 patients with significant (⩾50%) coronary stenosis at MDCTCA and CA underwent adjunctive bypass surgery or coronary angioplasty. In 8 patients, MDCTCA overestimated the severity of the coronary lesions (>50% MDCTCA, <50% CA). No severe cardiovascular perioperative events such as myocardial ischaemia, myocardial infarction or cardiac failure occurred in any patient in Group 1. Conclusions: MDCTCA seems to be effective as a preoperative screening test prior to non-coronary cardiac surgery. In this era of cost containment and optimal care of patients, MDCTCA is able to provide coronary vessel and ventricular function evaluation and may become the method of choice for the assessment of a cardiovascular risk profile prior to major surgery.
The Value of Magnetic Resonance Imaging and Ultrasound in Undifferentiated Arthritis: A Systematic Review

Objective. To perform a systematic literature review of the diagnostic and prognostic value of magnetic resonance imaging (MRI) and ultrasound (US) in patients with undifferentiated peripheral inflammatory arthritis (UPIA), and to assess if MRI and US should be done at baseline and repeated, and if so, at what interval. Methods. Medline, Embase, the Cochrane Library, and abstracts presented at the 2007 and 2008 meetings of the American College of Rheumatology and European League Against Rheumatism meetings were searched for diagnostic and prognostic studies of any duration examining the ability of MRI/US to predict outcome of patients with UPIA. Sensitivity, specificity, predictive values, and positive/negative likelihood ratios (LR+/LR−) were calculated. When available, odds ratios were extracted. Quality was appraised using validated scales. Results. Regarding MRI, 11 out of 2595 screened references were included: 2 described pure undifferentiated arthritis (UA) populations and 9, mixed populations. Bone edema (LR+ 4.5) and combination of a distinct MRI synovitis and erosion pattern (LR+ 4.8) increased probability of developing rheumatoid arthritis (RA). Absence of MRI synovitis (LR− 0.2) and absence of a distinct synovitis pattern (LR− 0) decreased probability of developing RA. Regarding US, 2 out of 2111 references were included, both mixed populations; no data could be extrapolated for UPIA. Conclusion. MRI bone edema and combined synovitis and erosion pattern seem useful in predicting development of RA from UPIA. The value of US in UPIA remains to be determined. The absence of MRI synovitis seems useful in excluding development of RA. No data were found about the value of repeating MRI/US. Studies evaluating MRI/US in UPIA are scarce, but current knowledge strongly encourages further testing in UA.
