Trading volume movement prediction is the key in a variety of financial applications. Despite its importance, there is few research on this topic because of its requirement for comprehensive understanding of information from different sources. For instance, the relation between multiple stocks, recent transaction data and suddenly released events are all essential for understanding trading market. However, most of the previous methods only take the fluctuation information of the past few weeks into consideration, thus yielding poor performance. To handle this issue, we propose a graph-based approach that can incorporate multi-view information, i.e., long-term stock trend, short-term fluctuation and sudden events information jointly into a temporal heterogeneous graph. Besides, our method is equipped with deep canonical analysis to highlight the correlations between different perspectives of fluctuation for better prediction. Experiment results show that our method outperforms strong baselines by a large margin.

FIIs are companies registered outside India. In the past four years there has been more than $41 trillion worth of FII funds invested in India. This has been one of the major reasons on the bull market witnessing unprecedented growth with the BSE Sensex rising 221% in absolute terms in this span. The present downfall of the market too is influenced as these FIIs are taking out some of their invested money. Though there is a lot of value in this market and fundamentally there is a lot of upside in it. For long-term value investors, there’s little because for worry but short term traders are adversely getting affected by the role of FIIs are playing at the present. Investors should not panic and should remain invested in sectors where underlying earnings growth has little to do with financial markets or global economy.

Outsourcing has grown enormously over the past few years, however, most of the attention so far has focused on the economics of the transaction, and much less on the human element involved in the transaction. In this paper I focus on call agents and my observations are based upon existing literature and my personal interviews. I suggest that it is challenging for them to identify with client organizations because of cultural differences, tacit contexts and lean communication media used to connect across vast geographical distances. The weak client identification may result in poor performance, inability to build trust with customers and long-term customer satisfaction. However, there are differences across individuals in their ability to deal with these challenges. Those who have a higher self-efficacy, higher pro-activeness and higher cultural intelligence may be more capable than others in their effectiveness. Likewise, organization initiated practices such as careful employee selection, intensive training and use of visible markers of identity may heighten client identification.

Gay rights and marriage equality have advanced so far in the U.S. in the past decade that it would be all too easy to assume that the struggle is over. The opponents of gay rights, however, remain powerful. Readers can take inspiration from how dramatically attitudes toward gay rights have liberalized in the past two decades and how transformative the liberalization of attitudes has been. We live in a world where political lies often seem to have the upper hand. It is worth remembering that despite the many short term advantages that lies can yield in politics, the truth has some long term advantages as well. The way the marriage equality movement prevailed should be a lesson to anyone who wants to make progressive social change.

AbstractMedical innovation has generated significant gains in health over the past decades, but these advances have been accompanied by rapid growth in healthcare spending. Faced with a growing number of high-cost but high-impact innovations, some have argued to constrain prices for new therapies – especially through global caps on pharmaceutical spending and limits on prices for individual drugs. We show that applying this threshold to past innovations would have limited access to many highly valuable drugs such as statins and anti-retrovirals. We also argue that budget caps violate several important principles of health policy. First, budget caps treat healthcare spending as a consumption good, like going to a movie or buying a meal. However, healthcare spending should be viewed as an investment, whose benefits accrue over many years – much like spending on education. Second, budgetary cost is a poor indicator of value, thereby distorting coverage decisions. Third, affordability arguments often use a short-term horizon, thereby missing that long-term health is society’s ultimate goal. Fourth, assessments of benefit should incorporate not just the immediate clinical benefit to patients, but also long-term health improvements, cost savings, and increased productivity. Fifth, global budget caps arbitrarily anchor spending on the status quo, thereby setting too stringent a threshold for socially-desirable innovation. In sum, a solitary focus on short-term costs can be detrimental to population health in the long-run. When medical treatment decisions are properly viewed as investments, budget caps are not the answer; rather, we need to find mechanisms to encourage spending decisions based on long-term value. Only then can we generate health returns to societal investments, while also encouraging the new research and development necessary to extend the gains of recent decades.

The introduction of the short term trading market (STTM) as the mechanism for supply of gas to both the Sydney and Adelaide markets presents a fundamental shift in the manner in which gas is provided to these markets, directionally leading to a more liquid market and increased efficiency of supply infrastructure, including potential implications for gas producers into the future.Traditionally, Sydney and Adelaide have been supplied with gas made available under long term contracts between retailers, producers and providers of gas pipeline infrastructure. The STTM has attempted to recognise the contribution and legal standing of these foundation arrangements while providing means by which an increased range of parties may offer gas directly to the market by removing the need for long term arrangements with a downstream counterparty. The ability to sell gas into these markets without having a defined downstream buyer potentially provides an additional route to market for producers.The STTM will begin operation on 4 June 2010, preceded by a trial period beginning in March 2010. This presentation will provide a description of the new market, any additional obligations for producers and, finally, an overview of opportunities the new market may provide.

Afghanistan has twice been thrust front and center of US national security concerns in the past half-century: first, during the Soviet-Afghan War, when Afghanistan served as a proxy for American efforts to combat Soviet influence; and second, as the frontline state and host for America’s global response to al-Qaida’s terrorist attacks of 2001. In both instances, American involvement swung from intensive investment and engagement to withdrawal and neglect. In both cases, American involvement reflected US concerns more than Afghan realities. And both episodes resulted in short-term successes for American security with long-term consequences for Afghanistan and its people. The signing of a strategic partnership agreement between the two countries in 2012 and a bilateral security agreement in 2013 created the possibility of a steadier and more forward-looking relationship—albeit one that the American and Afghan people may be less inclined to pursue as America’s longest war continues to grind on.

Abstract Accelerated eutrophication, which is harmful and difficult to repair, is one of the most obvious and pervasive water pollution problems in the world. In the past three decades, the management of eutrophication has undergone a transformation from simple directed algal killing, reducing endogenous nutrient concentration to multiple technologies for the restoration of lake ecosystems. This article describes the development and revolution of three remediation methods in application, namely physical, chemical, and biological methods, and it outlines their possible improvements and future directions. Physical and chemical methods have obvious and quick effects to purify water in the short term and are more suitable for small-scale lakes. However, these two methods cannot fundamentally solve the eutrophic water phenomenon due to costly and incomplete removal results. Without a sound treatment system, the chemical method easily produces secondary pollution and residues and is usually used for emergency situations. The biological method is cost-effective and sustainable, but needs a long-term period. A combination of these three management techniques can be used to synthesize short-term and long-term management strategies that control current cyanobacterial blooms and restore the ecosystem. In addition, the development and application of new technologies, such as big data and machine learning, are promising approaches.

In this paper, we investigate the relationship between unexpected information from postings and news, and the unexpected information is measured by the residual of regressions of trading volume on numbers of news or postings. We mainly find that (i) There are significant positive contemporaneous correlations between the unexpected information coming from postings and different kinds of news; the correlation between the unexpected information coming from postings and new media news is stronger than that between the unexpected information coming from postings and mass media news; (ii) The unexpected information coming from postings could cause the unexpected information coming from news, but only the unexpected information coming from the mass media news could cause that coming from postings; (iii) There are persistent power-law cross-correlations between the unexpected information coming from postings and that coming from mass media news and new media news. The cross-correlation between the unexpected information coming from postings and new media news is more persistent than the one between the unexpected information coming from postings and mass media news. The cross-correlations are all more stable in long term than in short term. We attribute our findings above to the dissemination speed of the information on the Internet.

Political scientists are only now, and dimly, beginning to recognize that something called “political risk analysis” (PRA) is very much in vogue in the corporate and banking communities of this country. Any attempt to assess this uncommon development should begin with this question: Why would any banker or corporate manager wish to spend hard cash on anything political scientists might have to say about places overseas where banks and multinational corporations lend or invest their capital? After all, the profession is not exactly distinguished by its ability to make accurate forecasts. Indeed, Sartori has argued that political scientists ought to eschew forecasting entirely in that they are best able to explain what happened as opposed to what may come to pass.Sartori's assertion of course would make historians of us all—and burden us with the historian's smug claim that, if the history examined is too recent, the immediacy of events will distort our vision and bias our judgments. Thus, rather than try to foretell where, say, Germany will move politically next year we should expend (more!) of our resources to establish once and for all what really caused Weimar to collapse and Hitler to come to power.This is not the stuff of political risk analysis. Growing interest in this activity is little based on broad analyses of the past or on long-term forecasts of future events. The potential consumers of political assessments are intelligent, harried bankers and corporate managers who are pressed to make relatively short-term decisions that affect the viability of enterprise and investment-and, equally important, careers-in professions where tenure is unknown.

Polyphenols are a group of widely distributed phytochemicals present in most foods of vegetable origin. A growing number of biological effects have been attributed to these molecules in the past few years and only recently has their interference with the transport capacity of epithelial barriers received attention. This review will present data obtained concerning the effect of polyphenols upon the transport of some compounds (organic cations, glucose and the vitamins thiamin and folic acid) at the intestinal and placental barriers. Important conclusions can be drawn: (i) different classes of polyphenols affect transport of these bioactive compounds at the intestinal epithelia and the placenta; (ii) different compounds belonging to the same phenolic family often possess opposite effects upon transport of a given molecule; (iii) the acute and chronic/short-term and long-term exposures to polyphenols do not produce parallel results and, therefore, care should be taken when extrapolating results; (iv) the effect of polyphenolics in combination may be very different from the expected ones taking into account the effect of each of these compounds alone, and so care should be taken when speculating on the effect of a drink based on the effect of one component only; (v) care should be taken in drawing conclusions for alcoholic beverages from results obtained with ethanol alone. Although most of the data reviewed in the present paper refer to in vitro experiments with cell-culture systems, these studies raise a concern about possible changes in the bioavailability of substrates upon concomitant ingestion of polyphenols.
