TL;DR: The authors proposed a unified three-stage theory of international expansion that incorporates both U-shaped and inverted-U-shaped relationship in a sigmoid hypothesis and tested this on data from 11 service industries, highlighting the difference between knowledge-based and capital-intensive service sectors.
Abstract: It is generally assumed that the performance of a firm improves with greater multinationality. Yet recent empirical studies have shown both a U-shaped relationship (which suggests an initially negative effect of international expansion on performance, before the positive returns of international expansion are realized) and an inverted-U-shaped relationship (which suggests that international expansion beyond an optimal level is again detrimental to performance, and results in a negative slope). This paper proposes a new unified three-stage theory of international expansion that incorporates both concepts in a sigmoid hypothesis. It then tests this on data from 11 service industries, highlighting the difference between knowledge-based and capital-intensive service sectors.

TL;DR: In this paper, the authors derived a second-order approximation to the solution of a general class of discretetime rational expectations models, and showed that the coe1cients on the terms linear and quadratic in the state vector are independent of the volatility of the exogenous shocks.

TL;DR: An approach in which Markov chain Monte Carlo simulations are used to integrate over the space of genealogies, whereas other parameters are integrated out analytically, resulting in an approximation to the full joint posterior density of the model parameters.
Abstract: In 1988, Felsenstein described a framework for assessing the likelihood of a genetic data set in which all of the possible genealogical histories of the data are considered, each in proportion to their probability. Although not analytically solvable, several approaches, including Markov chain Monte Carlo methods, have been developed to find approximate solutions. Here, we describe an approach in which Markov chain Monte Carlo simulations are used to integrate over the space of genealogies, whereas other parameters are integrated out analytically. The result is an approximation to the full joint posterior density of the model parameters. For many purposes, this function can be treated as a likelihood, thereby permitting likelihood-based analyses, including likelihood ratio tests of nested models. Several examples, including an application to the divergence of chimpanzee subspecies, are provided.

TL;DR: The structure of a protein triple helix has been determined by x-ray crystallographic studies of a collagen-like peptide containing a single substitution of the consensus sequence, which adopts a triple-helical structure that confirms the basic features determined from fiber diffraction studies on collagen.
Abstract: The structure of a protein triple helix has been determined at 1.9 angstrom resolution by x-ray crystallographic studies of a collagen-like peptide containing a single substitution of the consensus sequence. This peptide adopts a triple-helical structure that confirms the basic features determined from fiber diffraction studies on collagen: supercoiling of polyproline II helices and interchain hydrogen bonding that follows the model II of Rich and Crick. In addition, the structure provides new information concerning the nature of this protein fold. Each triple helix is surrounded by a cylinder of hydration, with an extensive hydrogen bonding network between water molecules and peptide acceptor groups. Hydroxyproline residues have a critical role in this water network. The interaxial spacing of triple helices in the crystal is similar to that in collagen fibrils, and the water networks linking adjacent triple helices in the crystal structure are likely to be present in connective tissues. The breaking of the repeating (X-Y-Gly)n pattern by a Gly-->Ala substitution results in a subtle alteration of the conformation, with a local untwisting of the triple helix. At the substitution site, direct interchain hydrogen bonds are replaced with interstitial water bridges between the peptide groups. Similar conformational changes may occur in Gly-->X mutated collagens responsible for the diseases osteogenesis imperfecta, chondrodysplasias, and Ehlers-Danlos syndrome IV.

TL;DR: The AABB developed this guideline to provide clinical recommendations about hemoglobin concentration thresholds and other clinical variables that trigger RBC transfusions in hemodynamically stable adults and children.
Abstract: Description: Although approximately 85 million units of red blood cells (RBCs) are transfused annually worldwide, transfusion practices vary widely The AABB (formerly, the American Association of Blood Banks) developed this guideline to provide clinical recommendations about hemoglobin concentration thresholds and other clinical variables that trigger RBC transfusions in hemodynamically stable adults and children Methods: These guidelines are based on a systematic review of randomized clinical trials evaluating transfusion thresholds We performed a literature search from 1950 to February 2011 with no language restrictions We examined the proportion of patients who received any RBC transfusion and the number of RBC units transfused to describe the effect of restrictive transfusion strategies on RBC use To determine the clinical consequences of restrictive transfusion strategies, we examined overall mortality, nonfatal myocardial infarction, cardiac events, pulmonary edema, stroke, thromboembolism, renal failure, infection, hemorrhage, mental confusion, functional recovery, and length of hospital stay Recommendation 1: The AABB recommends adhering to a restrictive transfusion strategy (7 to 8 g/dL) in hospitalized, stable patients (Grade: strong recommendation; high-quality evidence) Recommendation 2: The AABB suggests adhering to a restrictive strategy in hospitalized patients with preexisting cardiovascular disease and considering transfusion for patients with symptoms or a hemoglobin level of 8 g/dL or less (Grade: weak recommendation; moderate-quality evidence) Recommendation 3: The AABB cannot recommend for or against a liberal or restrictive transfusion threshold for hospitalized, hemodynamically stable patients with the acute coronary syndrome (Grade: uncertain recommendation; very low-quality evidence) Recommendation 4: The AABB suggests that transfusion decisions be influenced by symptoms as well as hemoglobin concentration (Grade: weak recommendation; low-quality evidence)
