161. THE COMMONWEALTH EMBLEM - C. Ducker
HIS PAPER CELEBRATES THE 40Th ANNIVERSARY of the Baillieu Library and at the same time shows how books in libraries are essential for the elucidation of botanical problems. It is the older generation of librarians and botanists that we have to thank, however, that we can use today their priceless heritage invested in the older books so necessary for stories of exploration and the science of botanical determination. To show how exploration and botanical history are integrated I have chosen the plants used as floral emblems of the States of the Commonwealth. All the floral emblems of Australia were chosen...

162. Original Article A cluster of deaths following influenza - Emilia Anisa; Alex Leventhala; Paul E. Slatera; Yael Arbelia; Yoram Sivana; Yitzhak Berlovitza; Boaz Leva
*Corresponding author. Abstract When four deaths occurred in one week among influenza vaccine recipients, the Israeli Health Ministry suspended its 2006 influenza vaccination campaign pending investigation of the causes of death. Medical histories of the deceased vaccinees, quality control reports, and laboratory test results were examined. Prior vaccine use that season and a risk assessment of the vaccinated population were also considered. All four decedents had been treated for cardiac and other chronic diseases, and none had experienced post-injection symptoms suggesting adverse reaction to influenza vaccine. Quality control and laboratory reports confirmed vaccine batch safety, and no adverse effects had...

163. Optimally solving dec-pomdps as continuous-state mdps - Jilles S. Dibangoye; Christopher Amato; Olivier Buffet
Optimally solving decentralized partially observ-able Markov decision processes (Dec-POMDPs) is a hard combinatorial problem. Current algorithms search through the space of full histories for each agent. Because of the doubly exponential growth in the number of policies in this space as the plan-ning horizon increases, these methods quickly be-come intractable. However, in real world problems, computing policies over the full history space is of-ten unnecessary. True histories experienced by the agents often lie near a structured, low-dimensional manifold embedded into the history space. We show that by transforming a Dec-POMDP into a continuous-state MDP, we are able to find and...

164. The E¤ects of Enforcement on Illegal Markets: Evidence from Migrant Smuggling along the Southwestern Border - Christina Gathmann; Jel Codes J K
Little is known about how enforcement a¤ects prices for illegal commodities. In this paper, we analyze how enforcement along the U.S.-Mexican border has a¤ected the prices and demand for illegal migrant smugglers. Using a unique dataset that links border crossing histories from illegal Mexican migrants to aggregate enforcement and punishment statistics, we …nd that the e¤ect of enforcement on smuggling prices is small. Though enforcement has more than tripled over the past fteen years, smuggling prices have increased by at most 30 percent. Unlike estimates from illegal drugs, the demand for border smugglers is however price elastic. We also show...

We announce the release of an advanced version of the Molecular Evolutionary Genetics Analysis (MEGA) software, which currently contains facilities for building sequence alignments, inferring phylogenetic histories, and conducting molecular evolutionary analysis. In version 6.0, MEGA now enables the inference of timetrees, as it implements the RelTime method for estimating divergence times for all branching points in a phylogeny. A new Timetree Wizard in MEGA6 facilitates this timetree inference by providing a graphical user interface (GUI) to specify the phylogeny and calibration constraints step-by-step. This version also contains enhanced algorithms to search for the optimal trees under evolutionary criteria and...

167. Contents - Wolfgang Schreiner; Temur Kutsia
We describe a static analysis that we have devised to determine whether a specification expressed in the LogicGuard language gives rise to a monitor that can operate with a fi-nite amount of resources, notably with finite histories of the streams that are monitored. This information can be passed to the runtime system of the monitor such that after every execution step the histories of the monitored streams can be appropriately pruned and the monitor can operate for an indefinite amount of time with a limited amount of memory. First, the analysis is presented for an abstract core language that monitors...

168. The E¤ects of Extended Unemployment Insurance Over the Business Cycle: Evidence from Regression Discontinuity Estimates over Twenty Years.Working Paper - Johannes F. Schmieder; Till Wachter; Stefan Bender; Steve Davis; Christian Dustmann; Johannes Görgen; Jennifer Hunt; Larry Katz; Kevin Lang; David Lee; Uliana Loginova; Patrycja Scioch; Stefan Seth Provided Sterling
Abstract: A goal of extending the duration of unemployment insurance (UI) in recessions is to reduce the rate of benefit exhaustion and hence increase coverage. However, such extensions potentially come at the cost of increased nonemployment durations. If UI benefit durations vary with the business cycle, it is very difficult to estimate the effects of this policy because of reverse causality. In this paper, we exploit the fact that the duration of UI benefits in Germany is a function of exact age that is invariant over the cycle. Using the universe of unemployment spells and career histories we implement a...

170. On Forced Temperature Changes, Internal Variability and the AMO - Michael E. Mann; Byron A. Steinman; Sonya K. Miller
This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process which may lead to differences between this version and the Version of Record. Please cite this article as doi: 10.1002/2014GL059233 ©2014 American Geophysical Union. All rights reserved. We estimate the low-frequency internal variability of Northern Hemisphere (NH) mean temperature using observed temperature variations, which include both forced and internal variability components, and several alternative model simulations of the (natural + anthropogenic) forced component alone. We then generate an ensemble of alternative historical temperature histories based on...

171. Magellanic Clues to Spatially-resolved Extinction Corrections for Distant Galaxies in the HST/JWST Era - Rolf A. Jansen; Duho Kim; Timothy Shewcraft; Rogier A. Windhorst; Kazuyuki Tamura
Extinction by dust hampers and possibly biases our understanding of galaxies at all redshifts. Moreover, extinction is not constant within or across the face of a galaxy, nor from galaxy to galaxy. We are testing an approximate spatially-resolved correction method for use with future JWST and existing HST imagery. Project Overview In Tamura et al. (2009), we presented an empirical method to correct galaxy images for extinction due to interstellar dust embedded within those galaxies (interspersed with their stellar populations) on a pixel by pixel basis, using only rest-frame 3.6 and 0.55µm (V-band) images. While this “βV ” method is...

173. 6. PERFORMING ORGANIZATION CODE - Hyerin Lee; Pardeep Kumar; Selim Gunay; Khalid Mosalam; Sashi Kunnath
objective of this project was to examine the effects of axial force variation in bridge columns due to strong vertical ground motions and the influence of these axial force fluctuations on shear strength degradation. Two quarter scale specimens (SP1 and SP2) with different transverse reinforcement ratios were constructed and tested on the UC-Berkeley shaking table at the Richmond Field Station. As a result of an extensive numerical investigation and preliminary fidelity tests, the 1994 Northridge earthquake acceleration recorded at the Pacoima Dam was selected as an input motion for the shaking table study. The chosen ground motion was applied to...

174. Topic 9: C2 - Richard Haberlin; Paulo Cesar; G Costa; Kathryn B. Laskey
A key component of Maritime Domain Awareness (MDA), situational awareness supports tactical decision making through fusion of intelligence, geography, environment, and the geopolitical situation. Advanced decision support systems will provide the decision maker with a number of hypotheses from which the evolving situation may be inferred, limited by the computational capacity of today’s computer hardware. In this context, a hypothesis can be thought of as a statement of anticipated action in which an actor will conduct an action against a target with a location, time and methodology of his choosing. Hypothesis Management is the control of exponential growth in fusion...

175. Overlap-hypercube Dirac operator - W. Bietenholza; I. Hipb
HMC histories for dynamical overlap fermions tend to stay in a xed top. sector for many trajectories. Therefore the suitable summation of observables, which have been measured in separate sectors, is a major challenge. We explore several techniques for this issue, based on data for the chiral condensate and \meson " masses in the 2- avour Schwinger model with dynamical overlap-hypercube fermions. 1 Schwinger model (QED2):

176. Detecting Change Patterns in Aspect Oriented Software Evolution: Rule-based Repository Analysis - Hanene Cherait; Nora Bounour
Interesting information and Meta-information about software systems can be extracted by analyzing their evolution histories. This information has been proved useful for understanding software evolution, predicting future changes, and performing an efficient change impact analysis. A rich source code repository is a prerequisite for a high quality evolution analysis. Nonetheless, the evolutionary information contained in current versioning systems for Aspect Oriented (AO) software is incomplete and of low quality, hence limiting the scope of AO software evolution analysis. In spite of AO Programming (AOP) characteristics, none of current versioning tools match the need of controlling and storing the AO software...

SIT-IN has a three-layer/multi-tier architecture. Layer 3. The data level is composed of a few RDB in-stances. In particular, on top of the spatial database, the...

178. TRAUMA TREATMENT A Controlled Pilot-Outcome Study of Sensory Integration (SI) in the Treatment of Complex Adaptation to Traumatic Stress - Erika M. Kaiser; Craig S. Gillette; Joseph Spinazzola
This study tested whether sensory integration (SI) treatment combined with psychotherapy would improve symptom outcome over psychotherapy alone in the treatment of complex posttrau-matic stress, as measured by the Disorders of Extreme Stress Not Otherwise Specified (DESNOS) clinical construct in a group of 10 adult patients with histories of childhood abuse. DESNOS symptoms were assessed at three time periods (T1, baseline; T2, after experi-mental group SI treatment; and T3, after wait-list control group SI treatment) using the Structured Interview for Disorders of Extreme Stress (SIDES). The Sensory Learning ProgramTM (SLP), developed by the Sensory Learning Institute of Boulder, Colorado, was...

179. Self-Modeling Agents Evolving in Our Finite Universe - Bill Hibbard
Abstract: This paper proposes that we should avoid infinite sets in definitions of AI agent and their environments. For agents that evolve to increase their fi-nite resources it proposes a self-modeling agent definition that avoids assump-tions about the agent's future form. And it proposes a consistent and complete logical theory for reasoning by AI agents in our finite universe. 1 Finitely Computable Agents According to current physics [1] our universe has a finite information capacity of no more than 10120 bits (1090 bits excluding gravitational degrees of freedom). Modeling artificial intelligence (AI) agents and environments with infinite sets, such as...

180. CLINICAL SCIENCE Role of Impression Cytology in Diagnosis of Ocular - Surface Neoplasia
Purpose: To compare the accuracy of impression cytology in the diagnosis of ocular surface neoplasia with tissue histology. Methods: We reviewed the histories of patients diagnosed with ocular surface neoplasia at the Chiang Mai University Hospital. All patients underwent both impression cytology and tissue biopsy. We compared the results of both methods. Results: There were 55 patients (33 men and 22 women), with an age range of 12–99 years (mean, 51 years). Twenty patients had lesions in the right eye and 35 had them in the left eye. The most common histologic report was conjunctival–corneal intraepithelial neoplasia (38.2%), followed by...
