Following a Royal Edict to adopt universal suffrage in election for local government institutions, maiden elections were held in 199 gewogs (counties) in Bhutan in 2002 to elect their chief executives. This paper gives an account of this first time event in a country where most villagers had never seen secret ballots and poll booths. It synthesizes detailed data, mostly qualitative, collected soon after the election was over, and assesses aspects of electoral participation that His Majesty the King of Bhutan has introduced steadily to deepen democracy. Beginning with a glance at the territorial organization of the Bhutanese state within which the counties are embedded, the paper compares the electoral results with the relevant election rules.

In the 2000s, the Philippines' local banking sector have conducted very conservative lending behavior and at the same time, gradually but continuously improved their profitability in terms of ROE (return on equity). A set of analyses on the flow of funds and segment reports (information) of local universal banks, whose loans outstanding to the industrial sector have dominated more than three fourths of the total outstanding, shows that (1) they have actively manage assets overseas, (2) their profitability has come from investment activities in the securities markets, and (3) some universal banks have shifted their resources into the consumer/retail segment. Although further refinement in the dataset is needed for a more detailed analysis, diverse business strategies would be expected among the local universal banks in the near future.

The central bank of the Philippines (Bangko Sentral ng Pilipinas, BSP) has improved its monetary policy measures since the 2000s. After rationalizing the country's banking sector since late-1990s, its monetary policy and the uniiversal/commercial banks' (UCBs) behavior in allocating their assets has changed since mid-2000s. Though further and more detailed studies are nesessary, based on the results of simple correlation analyses conducted in this paper suggest a possible mixture of the country's monetary policy and their own decision-making in asset allocations, instead of a "follow-through" attitude.

La sociedad y el mundo en general, en cuanto a la integración social de todos, han ido evolucionando favorablemente. La accesibilidad hoy en día ya no es un hecho que preocupe a una minoría, sino cada vez son más las personas que se dedican a que este desarrollo vaya por el buen camino. En este trabajo lo que se pretende es recoger las condiciones que deben tenerse en cuenta al proyectar, y sobre todo, las características que debe cumplir el mobiliario que vamos a escoger para nuestro edificio, de forma que facilitemos el uso del mismo a todas las personas, sea cual sea su condición, de una forma lo más autónoma, segura y confortable posible. Se presenta como ejemplo el Edificio Multidepartamental de la Universidad de Alcalá de Henares, situado en Guadalajara, sobre el que estudiaremos, mediante un modelo de fichas técnicas de diagnóstico y control, el mobiliario de las aulas, de la cafetería, los puntos de información, los espacios higiénico-sanitarios, el mobiliario urbano exterior y la señalización y paneles informativos. El mobiliario debe estar situado de forma que no entorpezca la circulación de los usuarios del centro y éste, debe poder ser utilizado por todos ellos, estudiantes con y sin discapacidad, profesores, etc.… Debe existir suficiente espacio alrededor de mesas y sillas para maniobrar y permitir la aproximación frontal de las personas en sillas de ruedas, también se debe evaluar la accesibilidad en aseos y baños, máquinas expendedoras….

Time series are proficiently converted into graphs via the horizontal visibility (HV) algorithm, which prompts interest in its capability for capturing the nature of different classes of series in a network context. We have recently shown [B. Luque et al., PLoS ONE 6, 9 (2011)] that dynamical systems can be studied from a novel perspective via the use of this method. Specifically, the period-doubling and band-splitting attractor cascades that characterize unimodal maps transform into families of graphs that turn out to be independent of map nonlinearity or other particulars. Here, we provide an in depth description of the HV treatment of the Feigenbaum scenario, together with analytical derivations that relate to the degree distributions, mean distances, clustering coefficients, etc., associated to the bifurcation cascades and their accumulation points. We describe how the resultant families of graphs can be framed into a renormalization group scheme in which fixed-point graphs reveal their scaling properties. These fixed points are then re-derived from an entropy optimization process defined for the graph sets, confirming a suggested connection between renormalization group and entropy optimization. Finally, we provide analytical and numerical results for the graph entropy and show that it emulates the Lyapunov exponent of the map independently of its sign.

We analyze the properties of networks obtained from the trajectories of unimodal maps at the transi- tion to chaos via the horizontal visibility (HV) algorithm. We find that the network degrees fluctuate at all scales with amplitude that increases as the size of the network grows, and can be described by a spectrum of graph-theoretical generalized Lyapunov exponents. We further define an entropy growth rate that describes the amount of information created along paths in network space, and find that such en- tropy growth rate coincides with the spectrum of generalized graph-theoretical exponents, constituting a set of Pesin-like identities for the network.
