In 'Privacy and Politics', Kieron O'Hara discusses the relation of the political philosophy of privacy to technical aspects in Web development. Despite a vigorous debate, the concept remains ambiguous, and a series of types of privacy is defined: epistemological, spatial, ideological, decisional and economic. Each of these has a different meaning in the online environment, and will be defended by different measures. The question of whether privacy is a right is raised, and generational differences in attitude discussed, alongside the issue of whether privacy should be protected in advance, via a consent model, or retrospectively via increased transparency and accountability. Finally, reasons both theoretical and practical for ranking privacy below other values (such as security, efficiency or benefits for the wider community) are discussed.

La transformación del régimen mexicano supone cambios en la relación básica entre el ejercicio del control corporativo y las formas de “gobernar el conflicto” en el espacio metropolitano. En este texto se sostiene la hipótesis de una “crisis decisional”, concebida como una serie de transformaciones en la organización y el ejercicio de liderazgos sociales e institucionales en años recientes (1991-2002), como la constitución de una “nueva” modalidad de lo político. A través de una revisión de la literatura reciente y de la revisión de tres bases de datos, se demuestra que en el campo de los servicios públicos como el agua estos “nuevos” liderazgos favorecerían escenarios de desfase y de renovación en el ejercicio de la legitimidad estatal.-----The transformation of the Mexican regime implies changes in the basic relationship between corporate control execution and ways of “controlling conflict” in the metropolitan areas. This paper sustains the hypothesis of a “decisional crisis” that is conceived as a series of transformations of the organization, and the exercise of social and institutional leadership in recent years (1991-2002) as the constitution of a “new” political mode. Through the review of recent literature and three databases, it is proved that in public service areas such as water, these “new” leaderships favor gap and renovation scenarios in the practice of state legitimacy.

El presente trabajo constituye un ejercicio analítico de fenómenos sociales categorizados bajo la etiqueta de actor no estatal; A su vez la monografía evalúa la dimensión diplomática de este tipo de actores a partir del estudio de los estímulos que recaen sobre ellos. Las herramientas de análisis se aglutinan en un modelo simplificado que recoge conceptos, reflexiones y adaptaciones teóricas que facilitan la comprensión de dichos actores desde diferentes aristas de su ejercicio político. El eje de esta investigación examina los alcances y las limitaciones que ha tenido la Organización Miss Universo dentro del periodo 1996-2012 e invita al lector a ampliar el abordaje, desde una óptica académica, de lo que representa un actor no estatal a nivel político internacional. El resultado de la implementación del modelo diseñado por el autor permite afirmar que la vocación diplomática dirigida por objetivos de escala internacional propia de un actor no estatal, deviene del tratamiento de los estímulos que recibe de su entorno en el marco de un núcleo decisional.

The industrial revolution and the subsequent industrialization of the economies occurred Orst in temperate regions. We argue that this and the associated positive correlation between absolute latitude and GDP per capita is due to the fact that countries located far from the equator suffered more profound seasonal auctuations in climate, namely stronger and longer winters. We propose a growth model of biased innovations that accounts for these facts and show that countries located in temperate regions were more likely to create or adopt capital intensive modes of production. The intuition behind this result is that savings are used to smooth consumption; therefore, in places where output auctuations are more profound, savings are bigger. Because the incentives to innovate depend on the relative supply factors, economies where savings are bigger are more likely to create or adopt capital intensive technologies.

The origins of early farming and its spread to Europe have been the subject of major interest for some time. The main controversy today is over the nature of the Neolithic transition in Europe: the extent to which the spread was, for the most part, indigenous and animated by imitatio (cultural diffusion) or else was driven by an influx of dispersing populations (demic diffusion). We analyze the spatiotemporal dynamics of the transition using radiocarbon dates from 735 early Neolithic sites in Europe, the Near East, and Anatolia. We compute great-circle and shortest-path distances from each site to 35 possible agricultural centers of origin—ten are based on early sites in the Middle East and 25 are hypothetical locations set at 58 latitude/longitude intervals. We perform a linear fit of distance versus age (and vice versa) for each center. For certain centers, high correlation coefficients (R . 0.8) are obtained. This implies that a steady rate or speed is a good overall approximation for this historical development. The average rate of the Neolithic spread over Europe is 0.6–1.3 km/y (95% confidence interval). This is consistent with the prediction of demic diffusion(0.6–1.1 km/y). An interpolative map of correlation coefficients, obtained by using shortest-path distances, shows that the origins of agriculture were most likely to have occurred in the northern Levantine/Mesopotamian area

In “How Judges Think” R. Posner’s main purpose is to develop a “cogent, unified, realist and appropriately eclectic account of how judges arrive to their decisions in nonroutine cases”. Because “law” is unnable to generate acceptable answers to all legal questions there’s an open area in which judges have decisional discretion. This article focuses on that concept of “open area” and in how judges behave when they are judging in the open area.

La presente investigación se enmarcó dentro del estudio científico del campo de la Administración Pública. La atención recayó sobre el Sistema Nacional de Gestión de Riesgos en Ecuador y la participación ciudadana dentro de sus procesos de toma de decisión en la elaboración, y posterior implementación, de políticas públicas para combatir diferentes posibilidades de desastre. Para el efecto de este estudio, el objetivo fue iluminar y explicar las falencias e incoherencias dentro del Sistema Nacional de Gestión de Riesgos en Ecuador a través del uso de los conceptos aplicables al espacio de la Administración Pública. De hecho, se partió de la teoría de la acción comunicativa de Jürgen Habermas, especialmente de su componente político de la ‘ciudadanía deliberativa’, y de los aportes investigativos en el campo de la gestión social de Fernando Tenório. Metodológicamente, se hizo uso del análisis del discurso para poder evidenciar y comprender cómo se define y ejerce el rol ciudadano dentro de este sistema, así como la importancia que la misma tiene en un sector en dónde la ciudadanía entra en relación con los representantes del componente científico-técnico y del político en la estructuración de planes comunitarios de acción contra el riesgo. Como resultado, puede evidenciarse que se dio un proceso de ordenamiento del Sistema Nacional de Gestión de Riesgos a través de la introducción de ciertos principios operativos a partir de 2007: la descentralización operativa y decisional, la incorporación social de una cultura de prevención de riesgos, y la centralidad de la participación ciudadana. Pero, el reconocimiento formal de estos principios no aparece como condición suficiente para un ejercicio real de participación ciudadana por la conjunción con ciertos factores que influencian de manera negativa en el funcionamiento del sistema: por ejemplo, la falta de delimitación de competencias claras entre los diferentes actores y la escasez de recursos de diferente tipo. Por último, cabe recalcar la importancia de este tipo de estudios sobre los diversos sistemas de Administración Pública en el país, pues es de vital importancia para comprender las condicionantes que limitan, así como las potencialidades, de los procesos políticos en Ecuador.

Stable hydrogen isotopes (δD) in flight feathers were measured to investigate the summer origins of five species of boreal-breeding warblers captured during fall migration at Canadian Migration Monitoring Network (CMMN) stations spread across southern Canada. Mean δD varied among stations and species within stations, but there was broad overlap in δD values. Although isotope ratios indicate that migrants at each station come from a wide range of latitudes, they are unable to provide much longitudinal discrimination. Band recoveries are sparse, but indicate that in general western Canadian warblers move southeast in fall, eastern birds move southwest, and there is a transition zone in the Great Lakes region. Combining knowledge of migratory direction with isotope results increases discrimination of breeding areas. Isotope results support fall migratory movements by Blackpoll Warbler (Dendroica striata) and Northern Waterthrush (Seiurus novaboracensis) that are more easterly than for other species, and in all study species, birds from more northern regions passed through southern Canada later in the season. Migration monitoring stations capture birds from broad areas of latitude, and migrants passing through each province appear to come from largely different portions of the Canadian breeding range, so a few stations placed in each province should suffice collectively to sample birds from most of the boreal forest. Migration monitoring in southern Canada, therefore, has the potential to monitor status of boreal forest birds in Canada that are unsampled by other monitoring programs.

The Canadian Migration Monitoring Network (CMMN) consists of standardized observation and migration count stations located largely along Canada’s southern border. A major purpose of CMMN is to detect population trends of migratory passerines that breed primarily in the boreal forest and are otherwise poorly monitored by the North American Breeding Bird Survey (BBS). A primary limitation of this approach to monitoring is that it is currently not clear which geographic regions of the boreal forest are represented by the trends generated for each bird species at each station or group of stations. Such information on “catchment areas” for CMMN will greatly enhance their value in contributing to understanding causes of population trends, as well as facilitating joint trend analysis for stations with similar catchments. It is now well established that naturally occurring concentrations of deuterium in feathers grown in North America can provide information on their approximate geographic origins, especially latitude. We used stable hydrogen isotope analyses of feathers (δ²Hf) from 15 species intercepted at 22 CMMN stations to assign approximate origins to populations moving through stations or groups of stations. We further constrained the potential catchment areas using prior information on potential longitudinal origins based upon bird migration trajectories predicted from band recovery data and known breeding distributions. We detected several cases of differences in catchment area of species passing through sites, and between seasons within species. We discuss the importance of our findings, and future directions for using this approach to assist conservation of migratory birds at continental scales.

A detailed view of Southern Hemisphere storm tracks is obtained based on the application of filtered variance and modern feature-tracking techniques to a wide range of 45-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) data. It has been checked that the conclusions drawn in this study are valid even if data from only the satellite era are used. The emphasis of the paper is on the winter season, but results for the four seasons are also discussed. Both upper- and lower-tropospheric fields are used. The tracking analysis focuses on systems that last longer than 2 days and are mobile (move more than 1000 km). Many of the results support previous ideas about the storm tracks, but some new insights are also obtained. In the summer there is a rather circular, strong, deep high-latitude storm track. In winter the high-latitude storm track is more asymmetric with a spiral from the Atlantic and Indian Oceans in toward Antarctica and a subtropical jet–related lower-latitude storm track over the Pacific, again tending to spiral poleward. At all times of the year, maximum storm activity in the higher-latitude storm track is in the Atlantic and Indian Ocean regions. In the winter upper troposphere, the relative importance of, and interplay between, the subtropical and subpolar storm tracks is discussed. The genesis, lysis, and growth rate of lower-tropospheric winter cyclones together lead to a vivid picture of their behavior that is summarized as a set of overlapping plates, each composed of cyclone life cycles. Systems in each plate appear to feed the genesis in the next plate through downstream development in the upper-troposphere spiral storm track. In the lee of the Andes in South America, there is cyclogenesis associated with the subtropical jet and also, poleward of this, cyclogenesis largely associated with system decay on the upslope and regeneration on the downslope. The genesis and lysis of cyclones and anticyclones have a definite spatial relationship with each other and with the Andes. At 500 hPa, their relative longitudinal positions are consistent with vortex-stretching ideas for simple flow over a large-scale mountain. Cyclonic systems near Antarctica have generally spiraled in from lower latitudes. However, cyclogenesis associated with mobile cyclones occurs around the Antarctic coast with an interesting genesis maximum over the sea ice near 150°E. The South Pacific storm track emerges clearly from the tracking as a coherent deep feature spiraling from Australia to southern South America. A feature of the summer season is the genesis of eastward-moving cyclonic systems near the tropic of Capricorn off Brazil, in the central Pacific and, to a lesser extent, off Madagascar, followed by movement along the southwest flanks of the subtropical anticyclones and contribution to the “convergence zone” cloud bands seen in these regions.

It is shown that Bretherton's view of baroclinic instability as the interaction of two counter-propagating Rossby waves (CRWs) can be extended to a general zonal flow and to a general dynamical system based on material conservation of potential vorticity (PV). The two CRWs have zero tilt with both altitude and latitude and are constructed from a pair of growing and decaying normal modes. One CRW has generally large amplitude in regions of positive meridional PV gradient and propagates westwards relative to the flow in such regions. Conversely, the other CRW has large amplitude in regions of negative PV gradient and propagates eastward relative to the zonal flow there. Two methods of construction are described. In the first, more heuristic, method a ‘home-base’ is chosen for each CRW and the other CRW is defined to have zero PV there. Consideration of the PV equation at the two home-bases gives ‘CRW equations’ quantifying the evolution of the amplitudes and phases of both CRWs. They involve only three coefficients describing the mutual interaction of the waves and their self-propagation speeds. These coefficients relate to PV anomalies formed by meridional fluid displacements and the wind induced by these anomalies at the home-bases. In the second method, the CRWs are defined by orthogonality constraints with respect to wave activity and energy growth, avoiding the subjective choice of home-bases. Using these constraints, the same form of CRW equations are obtained from global integrals of the PV equation, but the three coefficients are global integrals that are not so readily described by ‘PV-thinking’ arguments. Each CRW could not continue to exist alone, but together they can describe the time development of any flow whose initial conditions can be described by the pair of growing and decaying normal modes, including the possibility of a super-modal growth rate for a short period. A phase-locking configuration (and normal-mode growth) is possible only if the PV gradient takes opposite signs and the mean zonal wind and the PV gradient are positively correlated in the two distinct regions where the wave activity of each CRW is concentrated. These are easily interpreted local versions of the integral conditions for instability given by Charney and Stern and by Fjørtoft.

A multiple regression analysis of the NCEP-NCAR reanalysis dataset shows a response to increased solar activity of a weakening and poleward shift of the subtropical jets. This signal is separable from other influences, such as those of El Nino-Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO), and is very similar to that seen in previous studies using global circulation models (GCMs) of the effects of an increase in solar spectral irradiance. The response to increased stratospheric (volcanic) aerosol is found in the data to be a weakening and equatorward shift of the jets. The GCM studies of the solar influence also showed an impact on tropospheric mean meridional circulation with a weakening and expansion of the tropical Hadley cells and a poleward shift of the Ferrel cells. To understand the mechanisms whereby the changes in solar irradiance affect tropospheric winds and circulation, experiments have been carried out with a simplified global circulation model. The results show that generic heating of the lower stratosphere tends to weaken the subtropical jets and the tropospheric mean meridional circulations. The positions of the jets, and the extent of the Hadley cells, respond to the distribution of the stratospheric heating, with low-latitude heating forcing them to move poleward, and high-latitude or latitudinally uniform heating forcing them equatorward. The patterns of response are similar to those that are found to be a result of the solar or volcanic influences, respectively, in the data analysis. This demonstrates that perturbations to the heat balance of the lower stratosphere, such as those brought about by solar or volcanic activity, can produce changes in the mean tropospheric circulation, even without any direct forcing below the tropopause.
