This study explicitly rejects the prima facie proposition that top-tier investment banks are capable of delivering supernormal value creation to shareholders a REIT acquirer in corporate acquisition. Using event method, we find acquirers advised by market-leading suffer an average cumulative abnormal return −4.41% following M&A announcement, whereas non-top-tier only −1.49%. The evidence sh...

Our everyday surroundings besiege us with information. The battle is for a share of our limited attention and memory, with the brain selecting the winners and discarding the losers. Previous research shows that both bottom-up and top-down factors bias competition in favor of high priority stimuli. We propose that arousal during an event increases this bias both in perception and in long-term me...

[1] Broadband shear wave signals from 15 deep South American earthquakes reveal small-scale variations of the D00 shear velocity discontinuity beneath the Cocos Plate. Deconvolution by average event source wavelets allows multiple event and California station combinations to be double-array stacked in 4 geographically separate reflection point bins with lateral dimensions of about 200 km. Refle...

Communication is Logically Instantaneous (li) when there is a logical time frame in which for each message, the send event and the corresponding delivery events occur simultaneously. li is stronger than Causally Ordered (co) communication, but weaker than Rendezvous (rdv) communication. This paper explores Logically Instantaneous communication and provides a simple and eecient protocol that imp...

We present possible radio evidence of magnetic reconnection in a solar are { an LDE event of GOES class M3.2 that was observeed on 1999 February 16 on the disk. Our eveidence is based upon the facts that we observed a bright microwave source { blob at 17 and 34 GHz near the intersection of two seemingly intersecting aring loops or as a loop-top source above one aring loop. The bright microwave ...

This paper presents a procedure for constructing an Event Structure Lexicon (ESL), a resource which represents the lexically-entailed subevents in text as a support for textual inference tasks. The ESL is used as a resource for a subevent markup algorithm, called SUBEVITA, which annotates event implicatures on top of TimeML-based extraction algorithms. Such a resource can be used independently ...

Component frameworks such as the CORBA Component Model (CCM) and middleware services such as the CORBA Event Service are increasingly being used to build safety/mission-critical distributed real-time embedded (DRE) systems. In this paper, we present a novel model-checking infrastructure for checking global temporal properties of DRE systems built on top of a Real-Time CORBA Event Service using ...

Only recently, process mining techniques emerged that can be used for Operational decision Support (OS), i.e., knowledge extracted from event logs is used to handle running process instances better. In the process mining tool ProM, a generic OS service has been developed that allows ProM to dynamically interact with an external information system, receiving streams of events and returning meani...

One way to understand something is to break it up into parts. New research indicates that segmenting ongoing activity into meaningful events is a core component of ongoing perception, with consequences for memory and learning. Behavioral and neuroimaging data suggest that event segmentation is automatic and that people spontaneously segment activity into hierarchically organized parts and sub-p...

In this paper we describe an event-type extractor on top of a distributed search engine. We apply this event-type extractor in a case study concerned with assisting maritime security operators to assess potential risk factors of ships. Based on a corpus of maritime-related press releases we automatically investigate the history of ships as they enter an area of interest. The performance of the ...
