Spatial market expansion through mergers

In this paper we present a model that studies firm mergers in a spatial setting. A new model is formulated that addresses the issue of finding the number of branches that have to be eliminated by a firm after merging with another one, in order to maximize profits. The model is then applied to an example of bank mergers in the city of Barcelona. Finally, a variant of the formulation that introduces competition is presented together with some conclusions.Mergers, facility location, spatial competition

On the history of the oceans

I shall discuss two problems concerning the history of the ocean: {1) The volume of water on the earth\u27s surface at different times in the past. (2) Former conditions in the water and in the overlying atmosphere compared with those existing today. Specifically, we may ask whether the waters were acid, or slightly alkaline as at present, and whether conditions were oxidizing or reducing, that is, whether or not free oxygen was present

A vocational agriculture teacher\u27s analysis of artificial insemination of dairy cows in West Tennessee

This study was limited to the West Tennessee Artificial Breeding Association and local associations securing semen from this Association. It was necessary for all aspects of the program to be improved as soon as feasible. Future Farmers training for dairy farming used this service almost exclusively. The study was to show some of the good and weak aspects of the West Tennessee Artificial BreedingAssociation, and the services teachers of Vocational Agriculture might render farmers and boys in understanding and operating the program

1D to 3D Crossover of a Spin-Imbalanced Fermi Gas

We have characterized the one-dimensional (1D) to three-dimensional (3D) crossover of a two-component spin-imbalanced Fermi gas of 6-lithium atoms in a 2D optical lattice by varying the lattice tunneling and the interactions. The gas phase separates, and we detect the phase boundaries using in situ imaging of the inhomogeneous density profiles. The locations of the phases are inverted in 1D as compared to 3D, thus providing a clear signature of the crossover. By scaling the tunneling rate with respect to the pair binding energy, we observe a collapse of the data to a universal crossover point at a scaled tunneling value of 0.025(7).Comment: 5 pages, 4 figure

Supporting feature-level software maintenance

Software maintenance is the process of modifying a software system to fix defects, improve performance, add new functionality, or adapt the system to a new environment. A maintenance task is often initiated by a bug report or a request for new functionality. Bug reports typically describe problems with incorrect behaviors or functionalities. These behaviors or functionalities are known as features. Even in very well-designed systems, the source code that implements features is often not completely modularized. The delocalized nature of features makes maintaining them challenging. Since maintenance tasks are expressed in terms of features, the goal of this dissertation is to support software maintenance at the feature-level. We focus on two tasks in particular: feature location and impact analysis via feature coupling.;Feature location is the process of identifying the source code that implements a feature, and it is an essential first step to any maintenance task. There are many existing techniques for feature location that incorporate various types of analyses such as static, dynamic, and textual. In this dissertation, we recognize the advantages of leveraging several types of analyses and introduce a new approach to feature location based on combining dynamic analysis, textual analysis, and web mining algorithms applied to software. The use of web mining for feature location is a novel contribution, and we show that our new techniques based on web mining are significantly more effective than the current state of the art.;After using feature location to identify a feature\u27s source code, maintenance can be completed on that feature. Impact analysis should then be performed to revalidate the system and determine which other features may have been affected by the modifications. We define three feature coupling metrics that capture the relationship between features based on structural information, textual information, and their combination. Our novel feature coupling metrics can be used for impact analysis to quantify the strength of coupling between pairs of features. We performed three empirical studies on open-source software systems to assess the feature coupling metrics and established three major results. First, there is a moderate to strong statistically significant correlation between feature coupling and faults. Second, feature coupling can be used to correctly determine about half of the other features that would be affected by a change to a given feature. Finally, we found that the metrics align with developers\u27 opinions about pairs of features that are actually coupled

Report of Commmittee on Legal Services to the Armed Forces

Briefly the purpose of the committee was to be sure that the members of the armed forces, both who were serving in this state on leave, or are acquainted with death and loss in another state, and those of this state who are serving throughout the world, that they have the means of reaching legal services when they need them. The work of the committee is so that members of the armed services who were residents of the state of Washington, who have never had any contact with a lawyer and need one, go to a legal officer in the service, and that legal officer then does not give him advice but has the means before him to get that man in touch with a lawyer
