    Contender: A Resource Modeling Approach for Concurrent Query Performance Prediction

    Predicting query performance under concurrency is a difficult task that has many applications in capacity planning, cloud computing, and batch scheduling. The authors introduce Contender, a new resource modeling approach for predicting the concurrent query performance of analytical workloads. Contender's unique feature is that it can generate effective predictions for...

    SLA-Driven Workload Management for Cloud Databases

    Despite the fast growth and increased adoption of cloud databases, challenges related to Service-Level-Agreements (SLAs) specification and management still exist. Supporting application-specific performance goals and SLAs, assigning incoming query processing workloads to the reserved resources to avoid SLA violations and monitoring performance factors to ensure acceptable QoS levels, are some...

    Devel-Op: An Optimizer Development Environment

    Recent advances in the underlying architectures of DataBase Management Systems (DBMS) have motivated the redesign of key DBMS components such as the query optimizer. Optimizers are inherently difficult to build and maintain, and yet there exists no software engineering tools to facilitate their development. In this paper, the authors introduce...

    Supporting Extensible Performance SLAs for Cloud Databases

    Despite the fast growth and increased adoption of cloud databases the lack of application-specific Service-Level-Agreements (SLAs) hinders the adoption of cloud data services by large-scale enterprises. Defining application-specific QoS objectives and constraints, monitoring the performance factors to ensure acceptable QoS levels and isolating the source of QoS degradation, are some...

    Choosing the Right Technology for Your Speech Analytics Project

    Speech recognition technology is an important consideration for any successful speech analytics project. The core operation-finding exactly where a term was spoken in an audio file-has had many characterizations over the history of speech recognition, including words-potting, spoken term detection and audio mining - but a full speech analytics system...

    Information Technology, Globalization, And Growth: Role For Scale Economies, Terms Of Trade, And Variety

    This paper considers three channels through which globalization of information technology products may affect economic growth: terms of trade in IT products in international trade, economies of scale in IT production and trade, and variety in IT consumption and trade. The empirical question relevant for policy makers is, what is...

    Predicting Economic Market Crises Using Measures Of Collective Panic

    Predicting panic is of critical importance in many areas of human and animal behavior, notably in the context of economics. The recent financial crisis is a case in point. Panic may be due to a specific external threat, or self-generated nervousness. Here the authors show that the recent economic crisis...

    Credit Constraints, Learning And Aggregate Consumption Volatility

    This paper documents three empirical facts. First, the volatility of consumption growth relative to income growth rose from 1947-1960 and then fell dramatically by 50 percent from the 1960s to the 1990s. Second, the correlation between consumption growth and personal income growth fell by about 50 percent over the same...

    The Determinants Of Bilateral FDI: Is Asia Different?

    Intra-Asian Foreign Direct Investment (FDI) is dominated by flows from high technology economies to medium technology economies, while FDI elsewhere primarily consists of flows among high technology economies. This distinctive pattern is not due simply to differences in the relative distribution of Asian FDI recipients by technology, or to systematic...

    Thresher: An Efficient Storage Manager for Copy-on-Write Snapshots

    A new generation of storage systems exploits decreasing storage costs to allow applications to take snapshots of past states and retain them for long durations. Over time, current snapshot techniques can produce large volumes of snapshots. Indiscriminately keeping all snapshots accessible is impractical, even if raw disk storage is cheap,...

    Crises And Hedge Fund Risk

    The authors study the effects of financial crises on hedge fund risk and show that liquidity, credit, equity market, and volatility are common risk factors during crises for various hedge fund strategies. They also apply a novel methodology to identify the presence of a common latent (idiosyncratic) risk factor exposure...

    Adjustment To Foreign Changes In Trade Policy Under The WTO System

    How do domestic economies adjust when other countries change their trade policies? This question is increasingly important for at least two reasons associated with the current state of the global economy and rules-based trading system. First, the global economy is highly integrated through foreign direct investment, supply chains, and international...

    China, Japan, And The United States: Export-Led Growth, Reciprocity, And The Evolution Of The International Trading System

    First Japan and more recently China have pursued export-oriented growth strategies. While other Asian countries have done likewise, the cases of Japan and China are of particular interest because their economies are so large and the size of the associated bilateral trade imbalances with the United States so conspicuous. In...

    Trade Liberalization, Antidumping, And Safeguards: Evidence From India's Tariff Reform

    This paper is the first to examine empirically the relationship between import tariff cuts and the subsequent re-imposition of import protection under safeguard exceptions at the product-level. The authors approach overcomes potential endogeneity problems by focusing on the case of India, a country that underwent a major exogenous tariff reform...

    China's Social Security Policy In The Context Of Its Evolving Employment Policy

    In the evolution of China's social protection system, employment policy and pension policy have been closely intertwined, with employment considerations often dominating. The transition from socialism first sought to protect jobs, then to reduce redundancy, and used pension policies to support these approaches. Adverse effects could not be avoided, but...

    Supporting Generic Cost Models for Wide-Area Stream Processing

    Existing stream processing systems are optimized for a specific metric, which may limit their applicability to diverse applications and environments. This paper presents XFlow, a generic data stream collection, processing, and dissemination system that addresses this limitation efficiently. XFlow can express and optimize a variety of optimization metrics and constraints...
