A Class Of Large Global Solutions For The Wave-Map Equation

In this paper we consider the equation for equivariant wave maps from R3+1 to S-3 and we prove global in forward time existence of certain C-infinity-smooth solutions which have infinite critical Sobolev norm (H) overdot(3/4) (R-3) x (H) overdot(1/2) (R-3). Our construction provides solutions which can moreover satisfy the additional size condition parallel to u(0, .)parallel to L-infinity(vertical bar-vertical bar >= 1) > M for arbitrarily chosen M > 0. These solutions are also stable under suitable perturbations. Our method, strongly inspired by work of Krieger and Schlag, is based on a perturbative approach around suitably constructed approximate self similar solutions.

Parenteral opioids for maternal pain relief in labour.

BACKGROUND Parenteral opioids are used for pain relief in labour in many countries throughout the world. OBJECTIVES To assess the acceptability, effectiveness and safety of different types, doses and modes of administration of parenteral opioids given to women in labour. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (January 2010) and reference lists of retrieved studies. SELECTION CRITERIA We included randomised controlled trials examining the use of intramuscular or intravenous opioids (including patient controlled analgesia) for women in labour. We looked at studies comparing an opioid with placebo or another opioid. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed study eligibility, collected data and assessed risk of bias. MAIN RESULTS We included 54 studies involving more than 7000 women that compared an opioid with placebo or another opioid administered intramuscularly or intravenously. The 54 studies reported on 27 different comparisons, and for many outcomes only one study contributed data. Overall the evidence was of poor quality regarding the analgesic effect of opioids, satisfaction with analgesia, adverse effects and harm to women and babies. There were few statistically significant results. Many of the studies had small sample sizes, and low statistical power. Overall, findings indicated that parenteral opioids provided some pain relief and moderate satisfaction with analgesia in labour, although up to two-thirds of women who received opioids reported moderate or severe pain and/or poor or moderate pain relief one or two hours after administration. Opioid drugs were associated with maternal nausea, vomiting and drowsiness, although different opioid drugs were associated with different adverse effects. There was no clear evidence of adverse effects of opioids on the newborn. We did not have sufficient evidence to assess which opioid drug provided the best pain relief with the least adverse effects. AUTHORS' CONCLUSIONS Parenteral opioids provide some relief from pain in labour but are associated with adverse effects. Maternal satisfaction with opioid analgesia was largely unreported but appeared moderate at best. We did not examine the effectiveness and safety of parenteral opioids compared with other methods of pain relief in labour and this review needs to be examined alongside related Cochrane reviews. More research is needed to determine which analgesic intervention is most effective, and provides greatest satisfaction to women with acceptable adverse events for mothers and their newborns.
What Level of Competition Intensity Maximises Investment in the Wireless Industry?

This paper investigates the relationship between competition and investment in the wireless industry from a dynamic perspective. Using firm level data and instrumental variable estimation strategy, it finds that the relationship is inverted-U shaped. The investment maximising intensity of competition is reached when operators' gross profits represent 37 or 40 per cent of their revenues, depending on whether capital expenditures are normalised by the number of subscribers. This finding means that investment increases with competition as long as operators' profits are above the thresholds of 37 or 40 per cent of their revenues. Under these thresholds, there is a tradeoff between competition and investment. The paper also finds a significant long run effect of competition on investment which amplifies the short run effect by a factor of 3-4.

Intraretinal Neovascularization in Diabetic Retinopathy

lar pressure higher than 21 mm Hg, or history of intraocular surgery, steroid use, ocular trauma, or any ocular diseases were excluded. StratusOCT software version 3.0 or 4.0. 4 (model 3000; Carl Zeiss Meditec, Inc, Dublin, California) was used to measure the thickness of the peripapillary NFL. Eyes with OCT NFL images of poor signal quality or images in which the NFL segmentation algorithm failed to identify the NFL were excluded. The OCT measurements of the NFL in eyes with temporally and inferiorly tilted discs were compared with those of aged-matched healthy individuals without tilted discs.
The Impact of Motivation Enhancing Practices and Mediating Role of Talent Engagement on Turnover Intentions: Evidence from Malaysia

Employees are the backbone of any organization. Engaged and motivated employees enable the organization to gain the competitive advantage. Retention of employees is the main concern of organization now a days. The purpose of this study was to examine the direct relationship of motivation enhancing practices on turnover intentions and through talent engagement (job engagement and organization engagement) among the managers in hotel industry in Kuala Lumpur. This study investigated engagement in two dimensions. A total of 560 questionnaires were distributed to managers, who were working in three star, four star and five star hotels located in Kuala Lumpur. Structural equation modeling was applied to test the hypotheses. The study found that motivation enhancing practices (employee recognition, salary and perks, performance feedback, opportunities for advancement and development job security and workload) have significant negative relationship with employees’ turnover intentions. The interesting finding is that job engagement does not mediate between the motivation enhancing and turnover intentions while organization engagement statistically significant mediates the relationship. The findings of this study is important for hotels management to implement these motivation enhancing practices. Management of hotels should pay more attention to these motivation enhancing practices in order to retain the potential managers
Coherence and cohesion in EFL students' writing production: The impact of a metacognition-based intervention

The objective of this Action Research study was to identify the impact of metacognitive training on the development of coherence and cohesion in the writing production, at the paragraph level, of EFL learners. The participants included 19 students from an 8 th grade Chilean public school who took part in a 9-week class intervention. These classes focused on the students learning to write paragraphs in English by using metacognitive techniques such as planning, monitoring, and evaluating their own production while paying particular attention to coherence and cohesion. As instruments for data collection, L2 writing pre and post-tests were utilized. Additionally, two qualitative research techniques were employed to identify the metacognitive writing procedures used by the students before and after the metacognitive intervention. The results suggest that the EFL students used more metacognitive procedures when writing at the end of the intervention. Moreover, a slight improvement was observed in the area of cohesion.
CONFLICTS AND DELAYS IN INTERNATIONAL TRADE AGREEMENTS

Motivated by the current delay in WTO negotiations, we consider a model of a bilateral trade agreement in the presence of asymmetric cross-border externalities. In this model, we show that both countries conflict in their preferred set of policy agendas and thus have incentives to delay their negotiations. We also find that the extent of delay depends on the level of transfer between them. These results imply an importance of bilateral compensation scheme between developing and developed countries in the current WTO negotiations so as to reduce the delays.
Finding Pulsars in Real-Time

Finding new pulsars has always been a challenging problem, but this challenge is nowadays exacerbated by the increasing data rates of modern radio telescopes. Because of these increased data rates, traditional approaches to searching, based on storing data for off-line processing, are becoming unfeasible. Therefore, we propose a new pulsar searching pipeline that, by exploiting high-performance computing techniques, is able to process observational data in real-time. To achieve the real-time goal we parallelized all the steps of the pipeline to run on many-core accelerators, and used auto-tuning to adapt and optimize the pipeline for different platforms, telescopes, and searching parameters. In this paper, we test our pipeline on three different platforms: two Graphics Processing Units from AMD and NVIDIA, and an Intel Xeon Phi. Furthermore, we test it on three different scenarios, based on the operational parameters of three state-of-the-art telescopes. Results show that our pipeline can adapt to all tested platforms and scenarios, and achieves real-time performance and linear scalability. Because power consumption is a main concern for radio telescopes, and will be the main bottleneck for the construction of the Square Kilometer Array, we also measure the power consumed by our pipeline. By comparing the results obtained on many-core accelerators with the results obtained using a traditional multi-core CPU, we conclude that the accelerators can provide up to a factor 8 improvement in execution time, and up to a factor 6 reduction in power consumption.
The effects of sibutramine on the microstructure of eating behaviour and energy expenditure in obese women

Given the suggestion that many potential anti-obesity drugs may enhance within-meal satiation, few studies have directly measured the effects of any drug on the microstructure of human eating behaviour. The effects of 7 days dosing with sibutramine 10 mg and 15 mg a day on appetite and energy balance were determined in 30 obese women (BMI 34.6 ± 3.3 kg/m2, age 46.0 ± 12.9 years) using a Universal Eating Monitor (UEM) and indirect calorimetry, in a double-blind, placebo-controlled crossover study. At day 7, sibutramine 10 mg and 15 mg reduced food intake by 16.6% and 22.3%, respectively (p < 0.001), compared with placebo. Sibutramine reduced eating rate compared with placebo rather than meal length (10 mg p < 0.05; 15 mg p < 0.001). In addition, sibutramine 10 mg significantly reduced hunger later in the meal (p < 0.05) and sibutramine 15 mg increased fullness early in the meal (p < 0.01), both of which are consistent with enhanced within-meal satiation. Sibutramine had little effect on resting metabolic rate, although 15 mg did significantly reduce respiratory quotient at several time points during the test day. These results provide novel evidence that decreased consumption of a test meal induced by sibutramine is primarily because of reduced eating rate, enhancing the deceleration in cumulative food intake within a meal associated with the development of satiety. Changes in within-meal appetite ratings appear particularly sensitive to drug-induced enhancement of satiation, and may provide key indices for assessing the therapeutic potential of novel anti-obesity drugs.
THE IMPACT OF DEMOCRACY AND CORRUPTION ON THE DEBT-GROWTH RELATIONSHIP IN DEVELOPING COUNTRIES

The quality of governance, and in particular of the control of corruption and the level of democracy, is tested as a factor influencing the relationship between external debt (borrowing opportunities/constraints) and economic growth in a panel of 72 developing countries over the 1970-2005 period. Countries with lower corruption seem to be able to use and manage their debt better. Moreover, in countries with lower levels of corruption both the positive and negative effects of debt on growth, modelled with non-linear specifications, are significant. Furthermore, evidence cannot support a clear Debt-Laffer curve in our sample. The level of debt at which the effect of debt on growth becomes negative is also higher in countries with lower corruption levels. Finally, panel Granger-causality tests only weakly support the claim that causality runs from debt/institutional quality to growth. Despite our somewhat ambiguous results we conjecture some policy implications within the HIPC initiative and donori¯s approach to governance issues.
Does the Economic Crisis Have an Influence on the Higher Education Dropout Rate

ABSTRACTThis research aims to identify the effects of the economic crisis on higher education (HE) dropout rates at Lisbon School of Economics and Management (ISEG) – Universidade de Lisboa, after having controlled for individual characteristics, family background, High School and HE trajectories. Our main hypothesis is that the economic crisis induces higher dropout rates. The research emphasizes that, in the context of the European crisis, social, economic and political context should be taken into account in the dropout analysis model, together with university and student behaviour determinants. To analyse the impact of the economic crisis on dropout rates, we use longitudinal data from the ISEG database, and apply statistical methodologies such as Chi-square tests for independence, and t-tests for the equality of means and proportions. Our main results point to the fact that the economic and social crisis has significantly affected the dropout rate of Portuguese students. Dropout during the crisis per.
Does confrontation with potential goal failure promote self-regulation? Examining the role of distress in the pursuit of weight goals

How do people maintain goal pursuit when confronted with the risk of failure? In two studies (n = 62 and n = 49), we investigated whether a threat of failure manipulation, either or not involving the self, would affect self-regulation in women who were concerned about their weight. We expected that potential goal failure would result in greater distress and influence strategies for goal pursuit and self-control. Study 1, involving normal weight women, found that self-relevant goal threat resulted in greater distress but that distress did not affect self-regulation. Study 2, involving both normal weight and overweight women, found similar results. However, women who were exposed to objective goal threat and at the same time received feedback that the self was not involved spent more time on planning strategies for goal pursuit and demonstrated higher self-control. It is concluded that information emphasizing both opportunities for goal achievement and the necessity to act is sufficient for engaging in self-regulation.
Proactive vitality management and creative work performance

Integrating proactivity and creativity literatures, we argue that people can perform more creatively at work when they proactively manage their levels of vitality. Proactive vitality management is deﬁned as individual, goal-oriented behavior aimed at managing physical and mental energy to promote optimal function- ing at work. We hypothesize that this process may be facilitated by being aware of one’s own state and by support from others. A total of 242 employees participated in a weekly diary study for three consecutive weeks, yielding 610 observations. Results of multilevel analyses show that participants reported more creative work performance during weeks in which they had proactively used vitality management. In addition, in line with our predictions, self-insight and social support for creativity in the workplace acted as cross-level moderators and strengthened the relationship between proactive vitality management and creativity. We con- clude that a proactive approach regarding physical and mental energy is an important bottom-up strategy that may foster creativity in work settings.
Cre‐mediated recombination in mouse Clara cells

Clara cells are nonciliated secretory cells lining the respiratory epithelium and are easily identified by the expression of Clara cell secretory protein (CCSP). To investigate molecular mechanism(s) regulating Clara cell function in the lungs, Cre recombinase was inserted into exon 1 of the CCSP, generating two novel mouse models, CCSPCre‐Neo and CCSPCre. These two models differ only by the inclusion of the neomycin resistance gene. These mice were bred to the R26R reporter mouse to investigate the tissue and cell specificity of Cre‐mediated recombination. The efficiency of Cre recombination in the CCSPCre mouse model was higher than in the CCSPCre‐Neo mouse model. Recombination was detected at D 4.5 in CCSPCre‐Neo/R26R mice and at D 0.5 in CCSPCre/R26R mice. The CCSPCre‐Neo and CCSPCre mouse models provide valuable tools for the ablation of genes in the postnatal mouse Clara cells. genesis 46:300–307, 2008. © 2008 Wiley‐Liss, Inc.
Epab and Pabpc1 Are Differentially Expressed During Male Germ Cell Development

Modification of poly(A) tail length constitutes the main posttranscriptional mechanism by which gene expression is regulated during spermatogenesis. Embryonic poly(A)-binding protein (EPAB) and somatic cytoplasmic poly(A)-binding protein (PABPC1) are the 2 key proteins implicated in this pathway. In this study we characterized the temporal and spatial expression of Epab and Pabpc1 in immature (D6-D32) and mature (D88) mouse testis and in isolated spermatogenic cells. Both Epab and Pabpc1 expression increased during early postnatal life and reached their peak at D32 testis. This was due to an increase in both spermatogonia (SG) and spermatocytes. In the mature testis, the highest levels of Epab were detected in SG, followed by round spermatids (RSs), while the most prominent Pabpc1 expression was detected in spermatocytes and RSs. Our findings suggest that PABPC1 may play a role in translational regulation of gene expression by cytoplasmic polyadenylation, which occurs in spermatocytes, while both EPAB and PABPC1 may help stabilize stored polyadenylated messenger RNAs in RSs.
Modeling Energy Efficiency and Economic Growth: Evidences from India

India’s fossil fuel based energy-led economic growth has changed its pattern over a time and it is mainly driven by energy efficiency. In this paper, we have considered reduction in energy waste as a proxy of energy efficiency and analyzed its interplay with economic growth for 1971-2010. We have used Vector Error Correction model, and it has been seen that unidirectional causality exists from economic growth to energy waste, and this causal association is both short run and long run in nature. Moreover, energy waste is following a negatively elastic relationship with the economic growth along the energy efficiency frontier.
Does Income Converge among EU Member Countries following the Post-War Period? Evidence from the PANKPSS Test

In this study, we examine both stochastic and deterministic convergence in the logarithm of the relative per capita income of eighteen EU countries. The panel stationary test developed by Carrion-i Silvestre et al. (2005) is employed over the period 1950-2010. The univariate results attained from the stochastic convergence test provide that convergence does hold for sixteen countries except for Bulgaria and Ireland. In addition, the findings of the deterministic convergence test render the evidence favourable to convergence in sixteen EU countries as well, except for Austria and Greece. In other words, the individual results from panel stationarity tests are mostly in support of income convergence among EU members. Furthermore, both types of convergence appear to hold for the entire EU panel set. Therefore, shocks to relative per capita income levels of EU countries appear to be temporary.
The essential GTPase YphC displays a major domain rearrangement associated with nucleotide binding

The structure of a Bacillus subtilis YphC/GDP complex shows that it contains two GTPase domains that pack against a central domain whose fold resembles that of an RNA binding KH-domain. Comparisons of this structure to that of a homologue in Thermotoga maritima reveals a dramatic rearrangement in the position of the N-terminal GTPase domain with a shift of up to 60 Å and the formation of a totally different interface to the central domain. This rearrangement appears to be triggered by conformational changes of the switch II region in this domain in response to nucleotide binding. Modeling studies suggest that this motion represents transitions between the “on” and “off” states of the GTPase, the effect of which is to alternately expose and bury a positively charged face of the central domain that we suggest is involved in RNA recognition as part of the possible role of this enzyme in ribosome binding.
