Vietnamese and Chinese Labour Regimes: On the Road to Divergence

At a macro level the Chinese and Vietnamese industrial economies are developing in quite similar ways, with dramatic changes in their labour markets, employment systems and labour regimes. But it will be argued in this paper that they are also beginning to diverge along separate routes with regard to labour issues. It will be seen that the Vietnamese government has been more willing to grant trade unions some space to defend workers' interests, whereas the Chinese government has chosen to keep the unions under a tight rein.
Rad52 depletion in Candida albicans triggers both the DNA‐damage checkpoint and filamentation accompanied by but independent of expression of hypha‐specific genes

We have analysed the effect of RAD52 deletion in several aspects of the cell biology of Candida albicans. Cultures of rad52Δ strains exhibited slow growth and contained abundant cells with a filamentous morphology. Filamentation with polarization of actin patches was accompanied by the induction of the hypha‐specific genes (HSG) ECE1, HWP1 and HGC1. However, filament formation occurred in the absence of the transcription factors Efg1 and Cph1, even though disruption of EFG1 prevented expression of HSG. Therefore, expression of HSG genes accompanies but is dispensable for rad52Δ filamentation. However, deletion of adenylate cyclase severely impaired filamentation, this effect being largely reverted by the addition of exogenous cAMP. Filaments resembled elongated pseudohyphae, but some of them looked like true hyphae. Following depletion of Rad52, many cells arrested at the G2/M phase of the cell cycle with a single nucleus suggesting the early induction of the DNA‐damage checkpoint. Filaments formed later, preferentially from G2/M cells. The filamentation process was accompanied by the uncoupling of several landmark events of the cell cycle and was partially dependent on the action of the cell cycle modulator Swe1. Hyphae were still induced by serum, but a large number of rad52 cells myceliated in G2/M.
Indications and results of renal biopsy in children: a 10-year review from a single center in Serbia.

BACKGROUND This study was conducted to retrospectively investigate the indications for renal biopsy in native kidneys and to analyze pathological findings in the last 10 years in a single tertiary pediatric hospital in Serbia. METHODS All patients who underwent renal biopsy at our hospital between 2001 and 2010 were included in the present study. Renal biopsy was performed under fluoroscopy with a biopsy gun. All renal biopsies were studied under light and immunofluorescent microscopy, while electron microscopy was rarely performed. RESULTS The study group included 150 patients (56% female) who underwent 158 percutaneous native kidney biopsies. Median age was 11.5 years (range 0.2-20 years). The most frequent indications for renal biopsy were nephrotic syndrome (32.9%), asymptomatic hematuria (23.4%), urinary abnormalities in systemic diseases (15.8%) and proteinuria (11.4%). Primary glomerulonephritis (GN) was the most common finding (57.4%), followed by secondary GN (15.5%) and tubulointerstitial diseases (4.5%). According to histopathological diagnosis, the most common causes of primary GN were focal segmental glomerulosclerosis (20.9%), mesangioproliferative GN (14.6%), IgA nephropathy (8.9%) and minimal change disease (13%). Lupus nephritis (6%) and Henoch-Schönlein nephritis (4%) were the most common secondary glomerular diseases. CONCLUSIONS The epidemiology of glomerular disease in our single-center report is similar to that in data from adjacent Croatia and Greece. Focal segmental glomerulosclerosis was the dominant histopathological finding, followed by mesangioproliferative GN and IgA nephropathy.
Do False Predictions of Seizures Depend on the State of Vigilance? A Report from Two Seizure‐Prediction Methods and Proposed Remedies

Summary: Purpose: Available seizure‐prediction algorithms are accompanied by high numbers of false predictions to achieve high sensitivity. Little is known about the extent to which changes in EEG dynamics contribute to false predictions. This study addresses potential causes and the circadian distribution of false predictions as well as their relation to the sleep–wake cycle.
The effect of interactivity on initial interactions: the influence of information valence and modality and information richness on computer‐mediated interaction

Research investigating relationship development through computer‐mediated channels has failed to acknowledge the importance of initial interactions. Increasingly, multimodal forms of communication, such as audio‐ and videoconferencing, in addition to text‐only formats have emerged on socially oriented websites designed for relationship initiation. Utilizing the principle of interactivity as a conceptual framework, the present study investigates whether increased structural interactivity provided by the additional aural and visual modalities influences initial interaction processes and outcomes online. The results indicate that increased availability of nonverbal modalities, combined with the valence of the information acquired, significantly affected interaction involvement and mutuality, which are markers of processual interactivity, as well as the interaction outcomes of uncertainty, predicted outcome value, and information seeking. Additional analysis revealed that mutuality mediated the effect of richness on postinteraction uncertainty level and the evaluations of future relationship potential.
Seeing the wood through the trees: a review of techniques for distinguishing green fluorescent protein from endogenous autofluorescence.

The green fluorescent protein (GFP) from the jellyfish Aequorea victoria has recently leapt to prominence within numerous biological fields. Interest in the use of GFP has grown enormously over the past 5 years. The number of papers concerning GFP held in the Web of Science database, which abstracts the scientific literature (http://wos.mimas.ac.uk), rose from 13 in the period 1981–1994, to over 3400 in the period 1995 to October 2000. This is due to the ability to clone and heterologously express GFP genes in a diverse range of cells and organisms, from bacteria and yeast, to plants and mammals, coupled with favorable properties such as high stability, minimal toxicity, noninvasive detection, and the ability to generate the highly visible fluorophore in vivo in the absence of external cofactors. Thus, GFP has become a truly versatile marker for visualizing physiological processes, monitoring subcel-
Optimized Renewable and Sustainable Electricity Generation Systems for Ulleungdo Island in South Korea

The South Korean government has long been attempting to reduce the nation’s heavy reliance on fossil fuels and increase environmental safety by developing and installing renewable power generation infrastructures and implementing policies for promoting the green growth of Korea’s energy industry. This study focuses on the use of independent renewable power generation systems in the more than 3000 officially affirmed islands off Korea’s coast and proposes a simulated solution to the electricity load demand on Ulleungdo Island that incorporates several energy sources (including solar, batteries, and wind) as well as one hydro-electric and two diesel generators. Recommendations based on the simulation results and the limitations of the study are discussed.
Experiences of moral distress by privately hired companions in Ontario's long-term care facilities.

Purpose To explore long-term residential care provided by people other than the facilities' employees. Privately hired paid "companions" are effectively invisible in health services research and policy. This research was designed to address this significant gap. There is growing recognition that nursing staff in long-term care (LTC) residential facilities experience moral distress - a phenomenon in which one knows the ethically right action to take, but is systemically constrained from taking it. To date, there has been no discussion of the distressing experiences of companions in LTC facilities. This paper explores companions' moral distress. Design Data was collected using weeklong rapid ethnographies in seven LTC facilities in Southern Ontario, Canada. A feminist political economy analytic framework was used in the research design and in the analysis of findings. Findings Despite the differences in their work tasks and employment conditions, structural barriers can cause moral distress for companions. This mirrors the impacts experienced by nurses that are highlighted in the literature. Though companions are hired in order to fill care gaps in the LTC system, they too struggle with the current system's limitations. The hiring of private companions is not a sustainable or equitable solution to under-staffing and under-funding in Canada's LTC facilities. Value Recognizing moral distress and the impact that it has on those providing LTC is critical in terms of supporting and protecting vulnerable and precarious care workers and ensuring high quality care for Canadians in LTC.

How useful are course websites? A study of students' perceptions.

Course websites are increasingly used to augment in-class instruction in various disciplines, including the allied leisure, recreation and tourism (LRT) fields, despite the fact that their effectiveness has seldom been evaluated. This study examined 56 senior students’ use and perception of a course website designed for a recreation and facility planning course at North Carolina State University. Results show that most students had computer and Internet experience. Many students used the website often, particularly those components that were directly related to their final grades. The majority of the students preferred websites for future courses, but they did not prefer web-only courses without class meetings. Implications for instructors in the LRT fields and future research are discussed.
Cardiac Rehabilitation Exercise Training for High-Risk Cardiac Patients

Objective To examine the effect and safety of cardiac rehabilitation (CR) program in high-risk cardiac patients and compare these results to those of control CR participants without high-risk criteria. Methods A total of 12 high-risk cardiac patients were recruited as subjects. The high-risk criteria were: advanced heart failure with left ventricular ejection fraction (LVEF) of less than 30%, a recent history of cardiac arrest or dangerous arrhythmia, and cardiac device insertion. Another 12 CR participants without any high-risk criteria mentioned above were recruited as controls. Both groups underwent 6 to 8 weeks of CR exercise training. Exercise tolerance tests were performed before and after completion of the CR program. After CR completion, both groups were evaluated and their results were compared. Results After completion of the CR exercise program, both groups showed significant increases in peak oxygen uptake (VO2peak) and LVEF. In the control group (n=12), VO2peak increased from 25.9 to 31.8 mL/kg/min (changing rate, +21.4%±22.1%) and LVEF increased from 56.1% to 59.1% (changing rate, +5.3%±8.4%). In the high-risk group (n=12), VO2peak increased from 16.8 to 21.0 mL/kg/min (changing rate, +28.6%±21.4%) and LVEF increased from 26.1% to 29.4% (changing rate, +16.1%±12.9%). There was no serious cardiovascular event during all exercise hours. Conclusion High-risk cardiac patients who completed a supervised CR program demonstrated significant improvements in VO2peak and LVEF without any serious cardiovascular event. The improvement rate was similar to that of control group.
Combining Marriage and Career: The Marital Adjustment of Professional Women.

By.focusing on very highly educated women, the present study serves to further test the comprehensiveness of role theory as an explanation of the complex relationship between female employment and marital adjustment. The data are from a sample of 663 women who received high-level graduate degrees from a large midwestern university between 1964 and 1974. Because females with high-level degrees expected to make use of their training and pursue their careers, it was thought that in this instance the marital adjustment qf working women would be higher than that fbr nonworking women. The findings are in the predicted direction. However, looking at the various regression equations, it appears that it is not employment status per se that is important in determining marital adjustment but rather the extent to which family experiences accommodate the wife's employment. Having a supportive husband seems to be a major factor, i.e., one who is willing to quit his job and move to advance the wife's career; one who does not insist that the wife quit her job and move to advance his career; and one who shares similar values and beliefs, especially about women's employment, as represented by educational homogamy. Freedom from childbearing responsibilities is also important.
Organizational commitment and identification: An examination of conceptual and operational convergence

Organizational commitment and identification are two constructs that communication researchers currently utilize to study the employee‐organization relationship. A review of the literature reveals that the terms commitment and identification have distinct meanings, although they have been developed as virtual synonyms. This is especially true when comparing attitudinal commitment with identification as product. The review indicates that contemporary conceptualizations and operationalizations of attitudinal commitment (e.g., Mowday, Porter & Steers, 1982) and identification as product (e.g., Cheney, 1983a) reference the same cluster of attitudes. Additionally, an empirical study reported herein found that commitment and identification correlated consistently and similarly with relevant attitudinal, tenure, and demographic variables. This investigation concludes that communication scholars are advised to refer to identification as a process and commitment as an outcome of that process.
Beyond Invasion and Succession: School Segregation, Real Estate Blockbusting, and the Political Economy of Neighborhood Racial Transition

Recent urban scholarship has questioned the validity, methodology, and assumptions of the invasion‐succession model of neighborhood racial transition but has yet to elaborate a framework that extends beyond a critique of ecological theory. In this article, I use the theoretical insights of the sociospatial approach and draw on census data, government documents and reports, in‐depth interviews, and oral histories to examine the racial transition of southeast Kansas City, Missouri after 1950. I advance understanding of neighborhood transition by identifying the key actors, organized interests, and institutional forces that the invasion‐succession model has neglected to incorporate into its explanatory framework. I investigate the critical links between discriminatory school boundary decisions and real estate blockbusting in determining the timing, pace, and magnitude of racial succession. My objective is to fashion an alternative theory of neighborhood racial transition that takes into account the power of events to shape and transform ecological patterns, illuminates the interconnectedness of structural factors and human agency, and highlights the role of powerful actors and organized interests in marketing racial exclusion and reinforcing racially segregated settlement spaces.
Cognitive Radio Networks: A Practical Perspective

The FCC’s approval for the first commercial operation in TV white space gives new momentum to the development of cognitive radio in TVWS. On the other hand, the rapid growth of Cloud computing makes it possible and more economical to build a CR metropolitan area network with commodity hardware. In view of the opportunity and challenges brought about by these two technologies, we propose a CR cloud networking model that is able to support CR access in TVWS. Making use of the flexible and vast computing capacity of the cloud, a database and a cooperative spectrum sensing algorithm that estimates the radio power map of licensed users are realized on a CR cloud implemented with Microsoft’s Windows Azure Cloud platform. The CRC can support CSS, dynamic spectrum access and mobility management. A medium access control protocol is also developed for this CRCN model to collect sensing reports and provide access to the TVWS and CRC services. Through this CRCN prototype, important network parameters such as the mean squared errors in CSS, the CR channel vacating delay, and the cloud-based handover time are measured for the design and deployment of the CRCN concept. The authors propose a CR Cloud Networking model that is able to support CR access in TVWS. Making use of the flexible and vast computing capacity of the Cloud, a database and a cooperative spectrum sensing algorithm are realized on a CR Cloud (CRC) implemented with Microsoft’s Windows Azure Cloud
Firm Boundaries Matter: Evidence from Conglomerates and R&D Activity

This paper examines the impact of the conglomerate form on the scale and novelty of corporate Research and Development (R&D) activity. I exploit a quasi-experiment involving failed mergers to generate exogenous variation in acquisition outcomes of target firms. A difference-in-differences estimation reveals that, relative to failed targets, firms acquired in diversifying mergers produce both a smaller number of innovations and also less-novel innovations, where innovations are measured using patent-based metrics. The treatment effect is amplified if the acquiring conglomerate operates a more active internal capital market and is largely driven by inventors becoming less productive after the merger rather than inventor exits. Concurrently, acquirers move R&D activity outside the boundary of the firm via the use of strategic alliances and joint ventures. There is complementary evidence that conglomerates with more novel R&D tend to operate with decentralized R&D budgets. These findings suggest that conglomerate organizational form affects the allocation and productivity of resources.
Communication Networks : Measurement Techniques *

The idea of structure is one of the fundamental issues that any science must address. In its broadest sense, structure refers to the arrangement of the parts of the system that the science studies. Structure is fundamental because it significantly determines the processes of the system, that is, the ways in which the system can function or behave, The science of human communication studies the communication systems that people use as they live their daily lives. Like every. other scientific object, structure is a fundamental part of every communication system. Identification of this structure requires that we identify the people that comprise the various elements of the system and determine the arrangement of information exchange among these parts. In the science of human communication, the study of structure is usually undertaken under the rubric of network analysis. The general idea of a network is one that is familiar to most people since we have all had frequent contact with concrete networks such as telephones, highways, and electrical power lines. But networks of social structure, of which communication is one type, are harder. to identify. The difficulty stems from the fact that communication networks are comprised of abstract human behavior over time, rather than concrete physical material such as wires, pipes, and macadam. Communication networks, then, are the regular patterns of personto-person contacts that we discern as people exchange information in a human social system. By observing the communication behavior of people we can infer who is informationally connected to whom, and
Performance of QuantiFERON-TB Gold test compared to tuberculin skin test in detecting latent tuberculosis infection in HIV- positive individuals in Iran

BACKGROUND: There is limited data about the performance of QuantiFERON-TB Gold (QFT-G) test in detecting latent tuberculosis infection (LTBI) in our region. We intended to determine the performance of QFT-G compared to conventional tuberculin skin test (TST) in detecting LTBI in HIV-positive individuals in Iran. METHODS: This study was conducted in a HIV clinic in Tehran, Iran in April 2007. A total of 50 consecutive HIV-positive patients, not currently affected with active tuberculosis (TB), were recruited; 43 (86%) were male. The mean age was 38 ± 7.2 years (21–53). All had history of Bacillus Calmette Guerin (BCG) vaccination. A TST with purified protein derivative (PPD) and whole-blood interferon-gamma release assay (IGRA) in reaction to ESAT-6 and CFP-10 antigens was performed and measured by enzyme-linked immuno-sorbent assay (ELISA). The agreement between TST and QFT-G results were analyzed using Kappa test. RESULTS: A total of 36 (72%) patients had negative and 14 (28%) revealed positive TST. For QFT-G, 20 (40%) tested positive, 19 (38%) tested negative, and the results in 11 cases (22%) were indeterminate. A total of 14 (28%) patients had a CD4 count of <200. Of the 14, TST + group, 12 had QFT-G +, only one case TST+/QFT-G-, and QFT-G was indeterminate in one TST positive case. Of the 36 patients with negative TST tests, 8 (22%) had positive GFT-G and 10 (28%) yielded indeterminate results. There was no association between a positive TST and receiving highly active anti-retroviral therapy (HAART) or absolute CD4 counts. Similarly, the association between QFT-G results and receiving HAART or CD4 counts was not significant (P = 0.06). Although TST results were not significantly different in patients with CD4 < 200 vs. CD4 >200 (P = 0.295), association between QFT-G results and CD4 cutoff of 200 reached statistical significance (P = 0.027). Agreement Kappa coefficient between TST and QFT-G was 0.54 (Kappa = 0.54, 95% CI = 38.4-69.6,P < 0.001). CONCLUSION: Detecting LTBI in HIV-positive individuals showed moderate agreement between QFT-G and LTBI in our study. Interestingly, our findings revealed that nontuberculous mycobacteria and prior BCG vaccination have minimal influence on TST results in HIV patients in Iran.
