Background - The onset of bipolar disorder is influenced by the interaction of genetic and environmental factors. We previously found that a large increase in sunlight in springtime was associated with a lower age of onset. This study extends this analysis with more collection sites at diverse locations, and includes family history and polarity of first episode. Methods - Data from 4037 patients with bipolar I disorder were collected at 36 collection sites in 23 countries at latitudes spanning 3.2 north (N) to 63.4 N and 38.2 south (S) of the equator. The age of onset of the first episode, onset location, family history of mood disorders, and polarity of first episode were obtained retrospectively, from patient records and/or direct interview. Solar insolation data were obtained for the onset locations. Results - There was a large, significant inverse relationship between maximum monthly increase in solar insolation and age of onset, controlling for the country median age and the birth cohort. The effect was reduced by half if there was no family history. The maximum monthly increase in solar insolation occurred in springtime. The effect was one-third smaller for initial episodes of mania than depression. The largest maximum monthly increase in solar insolation occurred in northern latitudes such as Oslo, Norway, and warm and dry areas such as Los Angeles, California. Limitations - Recall bias for onset and family history data. Conclusions - A large springtime increase in sunlight may have an important influence on the onset of bipolar disorder, especially in those with a family history of mood disorders.

We report an investigation on the group delay spread in few-mode fibers operating in the weak and strong linear coupling regimes, and for the first time, we study the transition region between them. A single expression linking the group delay spread to the fiber correlation length is validated for any coupling regime, considering 3 guided modes.

The geographical, physical and biological aspects of the submarine canyons of the continental shelf off the coast of southern California have been described in earlier parts of this volume. Isopods were collected in 10 of the 15 canyons. Many benthic species were obtained since the specimens were obtained with a Campbell grab bottom sampler operated from the Hancock Foundation research vessel Velero IV.

En el interés de alcanzar la estabilidad y promover el mantenimiento de la paz internacional, la diplomacia preventiva nace como un concepto generador de estrategias encaminadas a actuar antes, durante y después del conflicto. El siguiente documento busca analizar el funcionamiento de los instrumentos de diplomacia preventiva empleados por las Naciones Unidas en la crisis de Kosovo de 1998 y 1999. Esta crisis surgida a raíz del conflicto entre el gobierno serbio y un movimiento disidente, conocido como el Ejército de Liberación Albano-Kosovar, que pretendía darle un perfil más autónomo al territorio y a la población albano-kosovar, reveló una serie de debilidades estructurales que sigue enfrentando este mecanismo en la resolución de conflictos étnicos al interior de los Estados.

El propósito central de este trabajo consiste en hacer un análisis crítico de la idea de educación democrática. Como hilo conductor se discute la tesis desarrollada por Amy Gutmann, según la cual, la educación democrática tiene como fin garantizar la reproducción consciente de la sociedad. En este contexto, la tesis que se defiende afirma que la educación democrática exige, además de los principios de no represión y la no discriminación desarrollados por Gutmann, un principio de reconocimiento, que articule la orientación de las acciones educativas a fuentes de normatividad asociadas con una interpretación intersubjetivista de la autonomía, de manera que se puedan generar más elementos de juicio, sobre todo, aquellos incorporados en las dimensiones moral, ética, política, legal y social de la persona, al momento de proponer prácticas educativas encaminadas a la formación de una ciudadanía participativa y crítica. Para esto se propone una interpretación que integra las perspectivas deliberativa y agonal de la democracia, se defiende que la expresión clave del ejercicio de la ciudadanía democrática es la participación, que el ejercicio de la participación tiene por condición la realización de la autonomía personal, por lo cual, en la parte final se elabora una lectura intersubjetivista de la autonomía, a partir de los trabajos de Axel Honneth y Rainer Forst.

Implantación de la Red de Alta velocidad Ferroviaria en California. Tramo Fresno-Los Angeles-San Diego. Este artículo, tercera parte de la serie que describe la red de Alta Velocidad Ferroviaria de California (CHSRS), se ocupa de la línea Fresno-Los Angeles Airport-San Diego Airport, con el trazado propuesto en la Alternativa Missions Trail del Proyecto FARWEST, caracterizada por el paso directo de las montañas de Tehachapi, mediante dos grandes túneles de 27,5 Km (17 mile) y 25,6 Km (15,9 mile) de longitud. También por el emplazamiento de la estación terminal de Los Angeles, junto al Aeropuerto Internacional de Los Angeles y la sustitución de la circunvalación ferroviaria de la aglomeración urbana de Los Angeles, a través de Inland Empire, por el ramal Anaheim-Riverside, que da acceso a esa región, y que es cabecera de la futura Dessert Express a Las Vegas. The third of a series describing the California High Speed Railway (CHSRS), this article refers to the Fresno-Los Angeles Airport-San Diego Airport line, with the alignment as proposed in the Missions Trail Alternative of the FARWEST Project, characterized by the direct Tehachapi mountain pass through two large tunnels 27.5 Km (17 miles) and 25.6 Km (15.9 miles) long and also to the siting of the Los Angeles terminal station next to the Los Angeles International Airport and the replacement of the Los Angeles urban conglomeration railway by-pass through Inland Empire, by the Anaheim-Riverside branch providing access to that region and which is the head of the future Desert Express to Las Vegas.

Mobile sensor platforms such as Autonomous Underwater Vehicles (AUVs) and robotic surface vessels, combined with static moored sensors compose a diverse sensor network that is able to provide macroscopic environmental analysis tool for ocean researchers. Working as a cohesive networked unit, the static buoys are always online, and provide insight as to the time and locations where a federated, mobile robot team should be deployed to effectively perform large scale spatiotemporal sampling on demand. Such a system can provide pertinent in situ measurements to marine biologists whom can then advise policy makers on critical environmental issues. This poster presents recent field deployment activity of AUVs demonstrating the effectiveness of our embedded communication network infrastructure throughout southern California coastal waters. We also report on progress towards real-time, web-streaming data from the multiple sampling locations and mobile sensor platforms. Static monitoring sites included in this presentation detail the network nodes positioned at Redondo Beach and Marina Del Ray. One of the deployed mobile sensors highlighted here are autonomous Slocum gliders. These nodes operate in the open ocean for periods as long as one month. The gliders are connected to the network via a Freewave radio modem network composed of multiple coastal base-stations. This increases the efficiency of deployment missions by reducing operational expenses via reduced reliability on satellite phones for communication, as well as increasing the rate and amount of data that can be transferred. Another mobile sensor platform presented in this study are the autonomous robotic boats. These platforms are utilized for harbor and littoral zone studies, and are capable of performing multi-robot coordination while observing known communication constraints. All of these pieces fit together to present an overview of ongoing collaborative work to develop an autonomous, region-wide, coastal environmental observation and monitoring sensor network.

Since the widely publicized revitalization success story of the Guggenheim Museum Bilbao, local governments have been scrambling to create their own flagship cultural projects. Because of the broad public sponsorship of such projects, urban planners need a full understanding of the associated potentials and problems. However, little research specifically examines the localized complexities of the flagship cultural strategy. Examining projects in Los Angeles, San Francisco, and San Jose, California, the article illustrates that much more than impressive architecture influences their catalytic ability. Flagship cultural projects are highly dependent on a variety of contextual factors and, therefore, should be positioned to build on existing arts and related commercial activity rather than gamble that they will generate new development from scratch.
