Swift observations of gamma-ray bursts

Since its launch on 20 November 2004, the Swift mission has been detecting approximately 100 gamma-ray bursts (GRBs) each year, and immediately (within approx. 90 s) starting simultaneous X-ray and UV/optical observations of the afterglow. It has already collected an impressive database, including prompt emission to higher sensitivities than BATSE, uniform monitoring of afterglows and a rapid follow-up by other observatories notified through the GCN. Advances in our understanding of short GRBs have been spectacular. The detection of X-ray afterglows has led to accurate localizations and the conclusion that short GRBs can occur in non-star-forming galaxies or regions, whereas long GRBs are strongly concentrated within the star-forming regions. This is consistent with the NS merger model. Swift has greatly increased the redshift range of GRB detection. The highest redshift GRBs, at z∼5–6, are approaching the era of reionization. Ground-based deep optical spectroscopy of high redshift bursts is giving metallicity measurements and other information on the source environment to a much greater distance than other techniques. The localization of GRB 060218 to a nearby galaxy, and the association with SN 2006aj, added a valuable member to the class of GRBs with detected supernova.
A Step to the Left? Or Just a Jump to the Right? Making Sense of the Third Way on Government and Governance

Since the early 1990s, Left-of-Centre political parties around the world have been engaged in an attempt to redefine their politics under the banner of the 'Third Way'. In attempting to understand the Anglo-American versions of the Third Way, this article argues that while there are clear continuities between the governments of the Third Way and their conservative predecessors, a more accurate precedent can be found in the successive Labor governments in Australia between 1983 and 1996. While this connection has been noted elsewhere, this article seeks to draw it out in terms of the underlying rationale and conception of government. It argues that the proponents of the Third Way share a common perception that government has become 'overloaded' with responsibilities and that they utilise market mechanisms as a pragmatic response to this, which distinguishes them from the New Right's moral critique of the state. The conclusion suggests that although this has the potential to open a space for thinking about how government might proceed differently, the Third Way has thus far failed to realise this potential.
Changes in fat but not fruit and vegetable intakes linked with body weight change in Mexican women immigrants in Quebec

The objective of the present study was to identify dietary parameters for predicting body weight change (ΔBW) in Mexican-born women (Mexicans) following immigration to Quebec City, Canada. Methods: Changes in fruit (ΔF), vegetable (ΔV), fruit and vegetable (ΔFV), and fat (ΔFat) intake were assessed according to post-immigration periods (1-5 years, 6-10 years, 11-20 years) using a food frequency questionnaire (FFQ). Anthropometric measures were also conducted in 87 Mexicans (study group) and 88 native-born Quebecers (comparison group) aged 18-65 years. Associations were calculated using full and partial robust regression models adjusting for potential confounders (origin, education, income, age, length of residence in Quebec City). Results: There was no difference in ΔBW between the groups. Body weight (BW) increased significantly in both Mexican (5.5 ± 0.9 kg, P P β = 0.03, P = 0.003), but not correlated with origin, ΔF, or ΔV. ΔBW was negatively associated with education (β = –4.33, P = 0.007) and positively associated with length of residence (β = 0.3, P = 0.003). Partial models indicated ΔF (β = –1.35, P β = –1.04, P = 0.0001), and ΔFV (β = –2.27, P β = 0.16, P = 0.04) was positively associated with ΔFat. Conclusions: Change in body weight could be predicted by length of residence, education, and change in fat intake in Mexican immigrant women and native-born Quebecers whereas changes in fruit and vegetable intakes could be predicted by Mexican or Quebec origin.
Currency and Interest-Rate Derivatives Use in US Firms

This study examines derivatives use in samples of 451 Fortune 500/S&P 500 (FSP) firms and 461 randomly selected firms. We find that over 61% of the FSP firms and 36% of the random firms use derivatives. In both samples, swaps are the most often used interest-rate contract, and forwards and futures the most often used currency contract. The determinants of derivatives use differ across samples and definitions of derivatives use, and are largely consistent with theory. One exception is that the random firms' derivatives use and the theoretical determinants are not strongly related.
Global Rebalancing and the Future of the Sino-US Codependency

The crisis of 2008 has shown the unsustainability of the global imbalances centered on the US-China symbiotic relationship that characterized the previous decade. This has revived the so-called growth-rebalancing debate. In particular, the new emerging consensus calls for a re-orientation of the US economy away from consumption and toward exports, and for policy shifts that can help China to reduce its dependence on external demand and inefficiently high rates of capital accumulation. We discuss the economic and political feasibility of the proposed patterns of re-adjustment by focusing on the short-term and long-term trade-offs faced by the policy-makers. We argue that the rebalancing will be gradual and partial because of the costs associated with a radical shift in the growth models adopted by both countries. We believe that this scenario will be consistent with a world economy expanding at lower rates than over the past decade.

Refinements to the Sharpe Ratio – Evidence from Malaysian Equity Funds

Abstract We apply M-squared measure to evaluate the performance of Malaysian equity funds. Specifically, we show how financial leverage can be applied to increase the returns or to reduce the risk exposures of funds. Several alternative refinements to the original Sharpe ratio are also employed to evaluate the funds during periods of negative excess returns. We find that modified versions of Sharpe measure generally lead to similar performance rankings as the original Sharpe ratio. Our findings imply that while Sharpe ratio has experienced several methodological improvements, its basic underlying concept remains remarkably intact.
Restraining Yourself: Fiscal Rules and Stabilization

State budgets in the United States played a significant macroeconomic role in the 1970s and 1980s, and the level of cyclical responsiveness was affected by the severity of statutory and constitutional fiscal restraints. Moving from no fiscal restraints to the most stringent restraints lowered the fiscal offset to income fluctuations by around 40 percent. Simulations indicate that a reduction in aggregate fiscal stabilizers of this size could lead to a significant increase in the variance of aggregate output.
Public Opinion and Regional Integration

For the time being, at least, survey data is relevant to the study of regional integration chiefly insofar as it gives an indication of the influence of the public (and various elite groups) on the decisions of the respective national governments—and vice versa. As integration progresses in given regions our focus may change, and we may become primarily interested in the degree to which given groups direct support or demands toward supranational institutions. But for the present the basic question seems to be: To what extent do public preferences constitute an effective influence on a given set of national decisionmakers, encouraging them to make decisions which increase (or diminish) regional integration?
The Changing Roles Portrayed by Women in Indian Advertisements: A Longitudinal Content Analysis

The role of women has been changing over the years in various fields around the world like advertising, academics, politics, etc. Today 30% of employees in the software industry are women. They are also distinguishing themselves as professionals in different walks of life. But has the representation of women advertising changed over a period of time in advertisements? Or does it confirm to some of the traditional notions about women and their role in society? That is the question we wish to deal with in this paper. The first section gives a review of literature on gender role portrayals in advertising. The second section discusses the various hypotheses of the study and the theoretical foundation for the same. The third section discusses the methodology of the study and a detailed analysis of the results. The last section contains general discussion, implications of the study, scope for further research and conclusion.
The Pay-What-You-Want game: What can be learned from the experimental evidence on Dictator and Trust Games?

Abstract This paper introduces the Pay-What-You-Want game which represents the interaction between a buyer and a seller in a Pay-What-You-Want (PWYW) situation. The PWYW game embeds the dictator game and the trust game as subgames. This allows us to use previous experimental studies with the dictator and the trust game to identify three factors that can influence the success of PWYW pricing in business practice: (i) social context, (ii) social information, and (iii) deservingness. Only few cases of PWYW pricing for a longer period of time have been documented. By addressing repeated games, we isolate two additional factors which are likely to contribute to successful implementations of PWYW as a long term pricing strategy. These are (iv) communication and (v) the reduction of goal conflicts. The central contribution of this study is an attempt to bridge the gap between laboratory experiments and the research on PWYW pricing, which relies largely on evidence from the field. By reviewing the relevant experiments, this study identifies factors crucial for the success of PWYW pricing and provides guidance to developing long-term applications of PWYW pricing.
Performance Analysis on Different Images using Reversible Data Hiding Technique and its Application

Communicating securely is what everyone wants. Earlier it was simply data hiding then reversible data hiding and currently its encrypted data hiding reversibly. Introducing new challenge is always as important as keeping it unreachable to the hacker. In proposed work security is enhanced by encrypting data and then embedding the encrypted form of data. Reserve Room before encryption gives an added advantage for enough space for data hiding. Haar wavelet is best suitable wavelet amongst other wavelet like symlet, bior, coiflet and contourlet, when the input image is encrypted image rather than a plain image. The quality of image has been evaluated by performance analysis like MSE, PSNR and hiding capacity on different types of color images and results were compared. Minimum errors with high SNR rate at various data hiding capacity were seen.

Stack-Pointer Networks for Dependency Parsing

We introduce a novel architecture for dependency parsing: stack-pointer networks (StackPtr). Combining pointer networks (Vinyals et al., 2015) with an internal stack, the proposed model first reads and encodes the whole sentence, then builds the dependency tree top-down (from root-to-leaf) in a depth-first fashion. The stack tracks the status of the depth-first search and the pointer networks select one child for the word at the top of the stack at each step. The StackPtr parser benefits from the information of whole sentence and all previously derived subtree structures, and removes the left-to-right restriction in classical transition-based parsers. Yet the number of steps for building any (non-projective) parse tree is linear in the length of the sentence just as other transition-based parsers, yielding an efficient decoding algorithm with O(n^2) time complexity. We evaluate our model on 29 treebanks spanning 20 languages and different dependency annotation schemas, and achieve state-of-the-art performances on 21 of them
Perceptions of Texas Landowners Regarding Fire and Its Use

Abstract Growing recognition that periodic fire is critical for maintaining the health of many rangeland ecosystems and concerns over more frequent catastrophic wildfires have focused attention on prescribed fire as an ecosystem restoration and fuel management tool. In states such as Texas, where most land is privately owned, the level of success of outreach activities aimed at expanding the adoption of specific management practices is influenced by the extent to which landowners' perceptions, interests, and concerns regarding such practices are addressed. This is particularly important for prescribed fire, which has been perceived by many landowners to be a dangerous or wasteful practice. Here we report the results of a mail survey of 185 members of the Edwards Plateau Prescribed Burn Association (EPPBA) and a random sample of 600 nonmember rural landowners in four counties in the Edwards Plateau and two counties in the Rolling Plains ecoregions of Texas. The overall response rate was 46.6%. Primary reasons respondents did not apply fire on their land were insufficient resources, legal concerns, and lack of assistance with burn plan development. EPPBA members had more positive attitudes than nonmembers about the ecological role of fire and the use of prescribed fire. Our study suggests that adoption of prescribed burning as an integral part of land management plans by private landowners could be expanded by forming new prescribed burning associations. The EPPBA model for such associations provides learning opportunities that are consistent with adult learning and innovation adoption principles. It facilitates fire safety training, reduces concerns over legal liability associated with fire ignition, and enhances access to shared fire management equipment and labor on burn days. The two-tiered structure of the EPPBA with some form of state-level representation appears to be an efficient organizational structure for these associations.
Alternative ribosomal proteins are required for growth and morphogenesis of Mycobacterium smegmatis under zinc limiting conditions

Zinc is an essential micronutrient required for proper structure and function of many proteins. Bacteria regularly encounter zinc depletion and have evolved diverse mechanisms to continue growth when zinc is limited, including the expression of zinc-independent paralogs of zinc-binding proteins. Mycobacteria have a conserved operon encoding four zinc-independent alternative ribosomal proteins (AltRPs) that are expressed when zinc is depleted. It is unknown if mycobacterial AltRPs replace their primary paralogs in the ribosome and maintain protein synthesis under zinc-limited conditions, and if such replacements contribute to their physiology. This study shows that AltRPs from Mycobacterium smegmatis are essential for growth when zinc ion is scarce. Specifically, the deletion mutant of this operon (ΔaltRP) is unable to grow in media containing a high-affinity zinc chelator, while growth of the wild type strain is unaffected under the same conditions. However, when zinc is gradually depleted during growth in zinc-limited medium, the ΔaltRP mutant maintains the same growth rate as seen for the wild type strain. In contrast to M. smegmatis grown with sufficient zinc supplementation that forms shorter cells when transitioning from logarithmic to stationary phase, M. smegmatis deficient for zinc elongates after the expression of AltRPs in late logarithmic phase. These zinc-depleted bacteria also exhibit a remarkable morphology characterized by a condensed chromosome, increased number of polyphosphate granules, and distinct appearance of lipid bodies and the cell wall compared to the zinc-replete cells. However, the ΔaltRP cells fail to elongate and transition into the zinc-limited morphotype, resembling the wild type zinc-replete bacteria instead. Therefore, the altRP operon in M. smegmatis has a vital role in continuation of growth when zinc is scarce and in triggering specific morphogenesis during the adaptation to zinc limitation, suggesting that AltRPs can functionally replace their zinc-dependent paralogs, but also contribute to mycobacterial physiology in a unique way.
‘It’s my home and your work’: the views of a filmed vignette describing a challenging everyday situation from the perspective of people with intellectual disabilities

ABSTRACT Purpose: Examining everyday challenges in the interactions between people with intellectual disabilities and their staff, as seen from the user’s perspective, is an important perspective in health care research. Involving people with intellectual disabilities as so-called co-researchers is a relatively unexplored research strategy. In this paper, co-researchers participated in all the steps of the research process, from planning to reporting, in addition to the written reporting of the findings. The aim of this study was to explore how people with intellectual disabilities experienced a filmed vignette of an everyday situation. Method: Based on audio-recorded and transcribed individual and focus-group interviews with people with intellectual disabilities, performed by co-researchers with intellectual disabilities together with researchers, qualitative content analysis was used. Results: The analysis reveals three themes: “being emotionally touched”, “being aware of the other”, and “being unclear”. Conclusions: The results are discussed in light of normalization and participation in society with independence and one’s own decision-making. Regarding the care of people with intellectual disabilities, the main finding is the need to focus not only on greater involvement of this population in their own daily lives, but also to teach self-determination skills. Another finding is the importance of involving people with intellectual impairment as co-researchers.
The influence of total quality management (TQM) on operational flexibility in Jordanian hospitals

Purpose – The importance of total quality management (TQM) to organizational achievement and performance has been established by many studies. Nevertheless, studies on the implementation of TQM and its relationship to operational flexibility have been limited, particularly in the developing countries. The purpose of this paper is to address this gap by exploring the extent of the application of TQM and its influence on operational flexibility in Jordanian hospitals.Design/methodology/approach – The study covers both public (King Abdullah University Hospital) and private (Jordan Hospital and Medical Center) health care services. A survey was conducted using a quantitative approach where the researchers distributed 400 questionnaires to selected respondents. The response rate was 57 percent out of the total questionnaires distributed. TQM is an independent variable which consists of eight principles, namely, leadership, employee management, information analysis, training, customer focus, continuous improvem.
21-Gene Recurrence Score Assay Predicts Benefit of Post-Mastectomy Radiotherapy in T1-2 N1 Breast Cancer

Purpose: Post-mastectomy radiotherapy (PMRT) yields improvements in both locoregional control and overall survival (OS) for women with T1-2 N1 breast cancer. The value of PMRT in this population has been questioned given advances in systemic therapy. The 21-gene recurrence score (RS) assay was evaluated as a predictor of OS among women with T1-2 N1 breast cancer who received or did not receive PMRT. Experimental Design: An observational cohort study was performed on women with T1-2 N1 estrogen receptor–positive breast cancer from the National Cancer Database (NCDB) and, as a validation cohort, from the surveillance, epidemiology, and end results (SEER) registry who underwent mastectomy and were evaluated for RS. Multivariable parametric accelerated failure time models were used to estimate associations of RS and PMRT with OS using propensity score-adjusted matched cohorts. Results: In both the NCDB (N = 7,332) and SEER (N = 3,087) cohorts, there was a significant interaction of RS and PMRT with OS (P = 0.009 and P = 0.03, respectively). PMRT was associated with longer OS in women with a low RS [NCDB: time ratio (TR) = 1.70; 95% CI (confidence interval), 1.30–2.22; P < 0.001; SEER: TR = 1.85; 95% CI, 1.33–2.57; P < 0.001], but not in women with an intermediate RS (NCDB: TR = 0.89; 95% CI, 0.69–1.14; P = 0.35; SEER: TR = 0.84; 95% CI, 0.62–1.14; P = 0.26), or a high RS (NCDB: TR = 1.10; 95% CI, 0.91–1.34; P = 0.33; SEER: TR = 0.79; 95% CI, 0.50–1.23; P = 0.28). Conclusions: Longer survival associated with PMRT was limited to women with a low RS. PMRT may confer the greatest OS benefit for patients at the lowest risk of distant recurrence. These results caution against omission of PMRT among women with low RS. Clin Cancer Res; 24(16); 3878–87. ©2018 AACR.
A Parameterised Carbon Feedback Model for the Calculation of Global Warming from Attainable Fossil Fuel Emissions

This paper evaluates the IPCC SRES scenarios against fossil fuel depletion models and proposes attainable carbon emissions trajectories. The contemporary carbon feedback cycle is then evaluated in light of recent studies and attainable carbon emissions. In light of deficiencies in the contemporary carbon feedback cycle, a parametric carbon feedback model is constructed that is consistent with empirical evidence. A radiative feedback model, that overestimates transient response when used in conjunction with equilibrium climate sensitivity, is then used in sensitivity studies to calculate the range of plausible global warming responses. The model predicts a maximum atmospheric concentration of CO2 in the range of 500–560ppm and a maximum global mean surface temperature increase of 1.5–2°C relative to year 2000.
Estimation of optimal portfolio compositions for Gaussian returns

We consider the expected return and the variance of the expected quadratic utility portfolio and the tangency portfolio. The expected returns on the individual assets and their covariance matrix are estimated by the sample mean and the sample covariance matrix. Replacing the unknown parameters by these estimators in the portfolio characteristics estimators of the expected portfolio return and the portfolio variance are obtained.
Lateral Inhibition-Inspired Convolutional Neural Network for Visual Attention and Saliency Detection

Lateral inhibition in top-down feedback is widely existing in visual neurobiology, but such an important mechanism has not be well explored yet in computer vision. In our recent research, we find that modeling lateral inhibition in convolutional neural network (LICNN) is very useful for visual attention and saliency detection. In this paper, we propose to formulate lateral inhibition inspired by the related studies from neurobiology, and embed it into the top-down gradient computation of a general CNN for classification, i.e. only category-level information is used. After this operation (only conducted once), the network has the ability to generate accurate category-specific attention maps. Further, we apply LICNN for weakly-supervised salient object detection.Extensive experimental studies on a set of databases, e.g., ECSSD, HKU-IS, PASCAL-S and DUT-OMRON, demonstrate the great advantage of LICNN which achieves the state-of-the-art performance. It is especially impressive that LICNN with only category-level supervised information even outperforms some recent methods with segmentation-level supervised learning.
