TL;DR: A large-scale assessment suggests that experimental reproducibility in psychology leaves a lot to be desired, and correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.
Abstract: Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

TL;DR: In this paper, the authors examined 433 mergers and acquisitions announcements associated with 58 emerging-market multinationals during the sample period 1991-2004 and found that cross-border expansions of EMMs through acquisitions do not create value, but point to value destruction for more than half of the transactions analyzed.
Abstract: The primary objective of this study is to examine the value implications of cross-border acquisitions of emerging-market multinationals (EMMs). We examine 433 mergers and acquisitions announcements associated with 58 EMMs during the sample period 1991–2004. The mergers and acquisitions announcements data come from the Thomson SDC Platinum database. We employ event study methodology to explore the impact of the announcements on the value of acquiring firms. The results show that, on average, cross-border expansions of EMMs through acquisitions do not create value, but point to value destruction for more than half of the transactions analyzed. To explore the factors influencing the direction and magnitude of market reaction, we analyze a cross-sectional sample of firms. While we find that target size, ownership structure of the target (private vs public), and structure of the bidder (diversified vs non-diversified) positively affect the bidder value, high-tech nature of the bidder and pursuit of targets in related industries negatively affect the bidder value. Our empirical findings provide some support for the positive impact of the stake pursued in the target firm and cultural distance, but not for the international experience and enhanced corporate governance.

TL;DR: The data support the prior rhinologic data in showing only a modest (and statistically insignificant) improvement in (geometric) mean nasal airflow following septal surgery alone, however, external valvular reconstruction alone increased airflow 2.6 times over preoperative values (n = 10).
Abstract: Despite the apparent association of nasal airway obstruction with septal deviation and/or inferior turbinate hypertrophy, increasing clinical evidence suggests that incompetence of the internal or external nasal valves may also affect airflow. But how much? What is the relative importance of the valves and septum in causing nasal airway obstruction? One-hundred and sixty consecutive patients (88 primary rhinoplasty, 72 secondary rhinoplasty) without turbinate hypertrophy or septal perforation and operated on for correctable nasal airway obstruction were evaluated prospectively by anterior active mask rhinomanometry preoperatively and from 1 to 43 months (mean 8.4 months) postoperatively after 1% phenylephrine decongestion to eliminate mucosal factors. Patients were stratified according to the site(s) of preoperative obstruction at the internal valves, the external valves, the septum, or any combination of the three. Geometric mean nasal airflow was calculated from independent measurements of each nasal airway. Surgical treatment consisted of submucous septal resection, internal valvular reconstruction with dorsal or spreader grafts, and external valvular reconstruction with cartilage or bone grafts; inferior turbinectomy was not performed. All procedures were performed endonasally. In the entire 160 patient study group, septal and/or valvular surgery corrected the airway in 152 patients (95 percent); 8 patients had partial residual obstruction. Our data support the prior rhinologic data in showing only a modest (and statistically insignificant, p < 0.4, n = 25) improvement in (geometric) mean nasal airflow following septal surgery alone. However, external valvular reconstruction alone increased airflow 2.6 times over preoperative values (n = 10). Internal valvular reconstruction alone by dorsal grafts (n = 17) or spreader grafts (n = 29) increased nasal airflow 2.0 times; spreader grafts and dorsal grafts were equally effective in supporting the internal valves. The largest improvement in postoperative airflow was seen in the patients with septal plus internal and external valvular incompetence (n = 21), in which flow increased 4.9 times over preoperative values (p < 0.0003). Patients in whom valvular incompetence alone was corrected experienced as much relative improvement as patients in whom valvular plus septal obstruction was corrected. Finally, valvular reconstruction in 54 secondary rhinoplasty patients who had previously undergone septoplasty corrected the airway obstruction in 49 patients (91 percent). Notably, 110 of 160 patients (69 percent) had a lateralized preoperative obstruction; however, the septum was deviated toward the clinically obstructed side in only 51 of these patients (46 percent); in the other 54 percent, the subjectively obstructed side was contralateral to the side toward which the septum was deviated. Nasal valvular function should be assessed in all preoperative rhinoplasty patients with airway obstruction; in many individuals, valvular effects may equal or surpass septal deviation as the primary cause of nasal airflow obstruction.

TL;DR: In this paper, the authors explored the role of mega-event impacts on perceived satisfaction with quality of life and support among South African residents before and after the 2010 FIFA World Cup.
Abstract: The purpose of the study was to explore the role of mega-event impacts on perceived satisfaction with quality of life and support among South African residents before and after the 2010 FIFA World Cup. Limited research has empirically tested whether quality of life (QOL) is perceived as an exchange benefit that facilitates resident support of mega-events. Intercept data were collected from residents in five host cities three months before (March 2010) and eight months after (March 2011) the event (N = 3,789). Results indicate significant differences in perceived impacts before and after the event. Before the event, the influence of political impacts, psychological impacts, and social benefits on perceived QOL was significant, while QOL mediated the relationships between political, psychological, and social benefit impacts and resident support. After the event, economic impacts emerged as a significant predictor of QOL in contrast to the preevent sample.
