Appropriate energy intake is important for the health and performance of athletes. When an athlete’s energy intake is not concordant with energy expenditure, short- and long-term performance can be compromised and negative health effects may arise. The energy intake patterns of athletes are subject to numerous effectors, including exercise response, time, and availability of food. To assess different determinants of energy intake in athletes, we reviewed recent literature regarding the response of appetite-regulating hormones to exercise, appetite perceptions following exercise, chronic exercise-induced adaptations regarding appetite, and social factors regarding energy intake. Additionally, we discussed consequences of aberrant energy intake. The purpose of this review is to clarify understanding about energy intake in athletes and provide insights into methods toward maintaining proper energy intake.

Despite the exponential growth of global hedge fund assets since the 1990s, the high attrition rates in the industry have raised an important issue about hedge fund return persistence. This chapter discusses the various statistical methodologies in measuring performance persistence and provides a comprehensive review of the empirical literature on short- and long-term performance persistence. In particular, the literature suggests that fund strategies and characteristics are related to performance persistence. The chapter also discusses three important issues: return smoothing, the use of option-like strategies, and data biases. The chapter provides additional empirical evidence on performance persistence, using a portfolio approach and a hedge fund sample from the Trading Advisor Selection System (TASS) database between 1994 and 2015.

The worldwide landscape for raising firm capital from Initial Public Offerings (IPOs) has significantly evolved over the last few decades. This introductory chapter reviews more recent research on initial public offerings. The Oxford Handbook of IPOs comprises twenty-nine chapters from authors around the world. The chapters describe the economics of going public, short- and long-term performance of IPOs, regulation of IPOs, IPOs versus acquisitions, reverse mergers, special purpose acquisition companies, service providers including investment banks and auditors, venture capital funds, international differences in IPOs, and crowdfunding. The Introduction summarizes the chapters that appear in the Handbook and highlight research trends on topic.

Practical Implications

Purpose This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings Hotels in the Asia-Pacific region have yet to fully utilize social media to promote their CSR initiatives. This means there is huge potential for improved stakeholder engagement, leading to short- and long-term performance gains. Originality The briefing saves busy executives, strategists and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Coarse Gravel

An Antarctic biopile using a composite liner (high-density polyethylene geomembrane (GMB) over a geosynthetic clay liner (GCL)) was constructed on a coarse granular subgrade to contain hydrocarbon-contaminated soil and leachate. The soil was remediated after 4 years and the biopile was decommissioned. The liner was exhumed to assess the properties and performance of the GMB and GCL. There was no significant change in the GMB index properties. Although cobbles and coarse gravel of the subgrade had left indentations in the GMB, implying tensile strains that could impact long-term performance, there were no holes. There was significant variability in the hydration of the GCL (from 10% to 220%) and in the underlying subgrade soil water content (from 5% to 30%). This reflects the complexity of the subgrade and groundwater flow in the Antarctic environment. The exhumed GCL specimens had low hydraulic conductivity (1 × 10−11 to 7 × 10−11 m/s) at 13 kPa. Soil samples from below the composite liner showed no detectable hydrocarbons and confirmed no migration through the barrier. It is concluded that the composite barrier contained the leachate and biopile soil over the 4 years in service in the extreme Antarctic conditions.

PurposeManagers face the challenge of balancing resources needed to support value creation and value appropriation. In this study the authors analyze the impacts of innovation investments (i.e. value creation: VC) on advertising expenditures (i.e. value appropriation: VA), and vice versa, and verify the effects of these options on short- and long-term performance.Design/methodology/approachThe effects of these two activities on short- and long-term performance were analyzed observing a panel of 4,090 companies of Standard and Poor's Compustat database from a 40-year period. The authors adopted the panel vector autoregressive (VAR) approach, using the generalized method of moments (GMM).FindingsAlthough there is a trade-off between the strategic emphases on creating and appropriating value, there is also a synergy between them. The results from the impulse response functions support the argument for a virtuous business circle: companies that choose to intensify their investments in R&D tend to increase advertising expenditures, and vice versa.Practical implicationsManagers, rather than having to deal with a trade-off between allocating resources either on VC or VA activities, can capitalize on synergetic benefits resulting from the interaction among them.Originality/valueThe relationship between the VC and VA activities transcends the trade-off imposed by resource restrictions, since the interaction between them creates additional benefits afforded by the synergy of these activities.

ONDRAF/NIRAS, the Belgian Agency for Radioactive Waste and Enriched Fissile Materials, and its partners have developed long-term safety and performance analyses in the framework of the license application for a surface disposal facility for low level radioactive waste (category A waste) at Dessel, Belgium. This paper focusses on the methodology of the safety assessments and on key results from the application of this methodology. An overview is given (1) of the performance analyses for the containment safety function of the disposal system and (2) of the radiological impact analyses confirming that radiological impacts are below applicable reference values and constraints and leading to radiological criteria for the waste and the facility. In this discussion, multiple indicators for performance and safety are used to illustrate the multi-faceted nature of long-term performance and safety of the surface disposal. This contributes to the multiple lines of reasoning for confidence building that a positive decision to proceed to the next stage of construction is justified.
