Politics of the 1945 Constitution:Democratization and Its Impact on Political Institutions in Indonesia

Introduction : Before 1998, no one could think about the amendment of the 1945 Constitution. The 1945 Constitution was a product of nationalist who had hard fought for independence from the Dutch colonization. This historical background made it the symbol of independence of the Indonesian nation. Thus, it has been considered as forbidden to touch contents of the 1945 Constitution whereas political leaders have legitimized their authoritarian rulership by utilizing a symbolic character of the Constitution. With the largest political turmoil since its independence, that is, a breakdown of authoritarian regime and democratic transformation in 1998-1999, however, a myth of the "sacred and inviolable" constitution has disappeared. A new theme has then aroused: how can the 1945 Constitution be adapted for a new democratic regime in Indonesia? 　　　The Indonesian modern state has applied the 1945 Constitution as the basic law since its independence in 1945, except for around 10 years in the 1950s. In the period of independence struggle, contrary to the constitutional provision that a kind of presidential system is employed, a cabinet responsible for the Central National Committee was installed. Politics under this institution was in practice a parliamentary system of government. After the Dutch transferred sovereignty to Indonesia in 1949, West European constitutionalism and party politics under a parliamentary system was fully adopted with the introduction of two new constitutions: the 1949 Constitution of Federal Republic of Indonesia and the 1950 Provisional Constitution of Republic of Indonesia. Since a return from the 1950 Constitution to the 1945 Constitution was decided with the Presidential Decree in 1959, the 1945 Constitution had supported two authoritarian regimes of Soekarno's "Guided Democracy" and Soeharto's "New Order" as a legal base. When the 32-year Soeharto's government fell down and democratization started in 1998, the 1945 Constitution was not replaced with a new one, as seen in many other democratizing countries, but successively reformed to adapt itself to a new democratic regime. In the result of four constitutional amendments in 1999-2002, political institutions in Indonesia are experiencing a transformation from an authoritative structure, in which the executive branch monopolized power along with incompetent legislative and judicial branches, to a modern democratic structure, in which the legislative branch can maintain predominance over the executive. However, as observed that President Abdurrahman Wahid, the first president ever elected democratically in Indonesian history, was impeached after one and a half years in office, democratic politics under a new political institution has never been stable. 　　　Under the 1945 Constitution, how did authoritarian regimes maintain stability? Why can a democratic regime not achieve its stability? What did the two constitutional amendments in the process of democratization change? In the first place, how did the political institutions stipulated by the 1945 Constitution come out? Through answering the above questions, this chapter intends to survey the historical continuity and change of political institutions in Indonesia along with the 1945 Constitutions and to analyze impact of regime transformation on political institutions. First, we examine political institutions stipulated by the original 1945 Constitution as well as historical and philosophical origins of the constitution. Second, we search constitutional foundations in the 1945 Constitution that made it possible for Soekarno and Soeharto to establish and maintain authoritarian regimes. Third, we examine contents of constitutional amendments in the process of democratization since 1998. Fourth, we analyze new political dynamics caused by constitutional changes, looking at the impeachment process of President Abdurrahman Wahid. Finally, we consider tasks faced by Indonesia that seeks to establish a stable democracy.

Evapotranspiration and crop coefficients of rice (Oryza sativa L.) under sprinkler irrigation in a semiarid climate determined by the surface renewal method

The evapotranspiration (ETc) of sprinkler-irrigated rice was determined for the semiarid conditions of NE Spain during 2001, 2002 and 2003. The surface renewal method, after calibration against the eddy covariance method, was used to obtain values of sensible heat flux (H) from high-frequency temperature readings. Latent heat flux values were obtained by solving the energy balance equation. Finally, lysimeter measurements were used to validate the evapotranspiration values obtained with the surface renewal method. Seasonal rice evapotranspiration was about 750–800 mm. Average daily ETc for mid-season (from 90 to 130 days after sowing) was 5.1, 4.5 and 6.1 mm day−1 for 2001, 2002 and 2003, respectively. The experimental weekly crop coefficients fluctuated in the range of 0.83–1.20 for 2001, 0.81–1.03 for 2002 and 0.84–1.15 for 2003. The total growing season was about 150–160 days. In average, the crop coefficients for the initial (Kcini), mid-season (Kcmid) and late-season stages (Kcend) were 0.92, 1.06 and 1.03, respectively, the length of these stages being about 55, 45 and 25 days, respectively.

Potencial de la producción de bioelectricidad de las Comarcas Agrarias de la Comunidad de Madrid en base a centeno y triticale

En el presente trabajo se estudia la producción potencial de biomasa procedente de los cultivos de centeno y triticale en las seis comarcas agrarias de la Comunidad de Madrid (CM) y la posibilidad de su aplicación a la producción de bioelectricidad en cada una de ellas. En primer lugar se realiza un estudio bibliográfico de la situación actual de la bioelectricidad. Uno de los principales datos a tener en cuenta es que en el PER 2011- 2020 se estima que el total de potencia eléctrica instalada a partir de biomasa en España en el año 2020 sea de 1.350 MW, unas dos veces y media la existente a finales de 2010. Además, se comenta el estado de la incentivación del uso de biomasa de cultivos energéticos para producción de electricidad, la cual se regula actualmente según el Real Decreto-ley 9/2013, de 12 de Julio, por el que se adoptaron medidas urgentes para garantizar la estabilidad financiera del sistema eléctrico, y se consideran los criterios de sostenibilidad en el uso de biocombustibles sólidos. Se realiza una caracterización de las seis comarcas agrarias que forman la Comunidad Autónoma de Madrid: Área Metropolitana, Campiña, Guadarrama, Lozoya- Somosierra, Sur-Occidental y Vegas, la cual consta de dos partes: una descripción de la climatología y otra de la distribución de la superficie dedicada a barbecho y cultivos herbáceos. Se hace una recopilación bibliográfica de los modelos de simulación más representativos de crecimiento de los cultivos (CERES y Cereal YES), así como de ensayos realizados con los cultivos de centeno y triticale para la producción de biomasa y de estudios efectuados mediante herramientas GIS y técnicas de análisis multicriterio para la ubicación de centrales de bioelectricidad y el estudio de la logística de la biomasa. Se propone un modelo de simulación de la productividad de biomasa de centeno y de triticale para la CM, que resulta de la combinación de un modelo de producción de grano en base a datos climatológicos y a la relación biomasa/grano media de ambos cultivos obtenida en una experiencia previa. Los modelos obtenidos responden a las siguientes ecuaciones (siendo TN = temperatura media normalizada a 9,9 ºC y PN = precipitación acumulada normalizada a 496,7 mm): - Producción biomasa centeno (t m.s./ha) = 2,785 * [1,078 * ln(TN + 2*PN) + 2,3256] - Producción biomasa triticale (t m.s./ha) = 2,595 * [2,4495 * ln(TN + 2*PN) + 2,6103] Posteriormente, aplicando los modelos desarrollados, se cuantifica el potencial de producción de biomasa de centeno y triticale en las distintas comarcas agrarias de la CM en cada uno de los escenarios establecidos, que se consideran según el uso de la superficie de barbecho de secano disponible (25%, 50%, 75% y 100%). Las producciones potenciales de biomasa, que se podrían alcanzar en la CM utilizando el 100% de la superficie de barbecho de secano, en base a los cultivos de centeno y triticale, se estimaron en 169.710,72 - 149.811,59 - 140.217,54 - 101.583,01 - 26.961,88 y 1.886,40 t anuales para las comarcas de Campiña - Vegas, Sur - Occidental - Área Metropolitana - Lozoya-Somosierra y Guadarrama, respectivamente. Se realiza un análisis multicriterio basado en la programación de compromiso para definir las comarcas agrarias con mejores características para la ubicación de centrales de bioelectricidad en base a los criterios de potencial de biomasa, infraestructura eléctrica, red de carreteras, espacios protegidos y superficie de núcleos urbanos. Al efectuar el análisis multicriterio, se obtiene la siguiente ordenación jerárquica en base a los criterios establecidos: Campiña, Sur Occidental, Vegas, Área Metropolitana, Lozoya-Somosierra y Guadarrama. Mediante la utilización de técnicas GIS se estudia la localización más conveniente de una central de bioelectricidad de 2,2 MW en cada una de las comarcas agrarias y según el uso de la superficie de barbecho de secano disponible (25%, 50%, 75% y 100%), siempre que exista potencial suficiente. Para el caso de la biomasa de centeno y de triticale en base seca se considera un PCI de 3500 kcal/kg, por lo que se necesitarán como mínimo 17.298,28 toneladas para satisfacer las necesidades de cada una de las centrales de 2,2 MW. Se analiza el potencial máximo de bioelectricidad en cada una de las comarcas agrarias en base a los cultivos de centeno y triticale como productores de biomasa. Según se considere el 25% o el 100% del barbecho de secano para producción de biomasa, la potencia máxima de bioelectricidad que se podría instalar en cada una de las comarcas agrarias variaría entre 5,4 y 21,58 MW en la comarca Campiña, entre 4,76 y 19,05 MW en la comarca Vegas, entre 4,46 y 17,83 MW en la comarca Sur Occidental, entre 3,23 y 12,92 MW en la comarca Área Metropolitana, entre 0,86 y 3,43 MW en la comarca Lozoya Somosierra y entre 0,06 y 0,24 MW en la comarca Guadarrama. La potencia total que se podría instalar en la CM a partir de la biomasa de centeno y triticale podría variar entre 18,76 y 75,06 MW según que se utilice el 25% o el 100% de las tierras de barbecho de secano para su cultivo. ABSTRACT In this work is studied the potential biomass production from rye and triticale crops in the six Madrid Community (MC) agricultural regions and the possibility of its application to the bioelectricity production in each of them. First is performed a bibliographical study of the current situation of bioelectricity. One of the main elements to be considered is that in the PER 2011-2020 is estimated that the total installed electric power from biomass in Spain in 2020 was 1.350 MW, about two and a half times as at end 2010. Also is discussed the status of enhancing the use of biomass energy crops for electricity production, which is currently regulated according to the Real Decreto-ley 9/2013, of July 12, by which urgent measures were adopted to ensure financial stability of the electrical system, and there are considered the sustainability criteria in the use of solid biofuels. A characterization of the six Madrid Community agricultural regions is carried out: Area Metropolitana, Campiña, Guadarrama, Lozoya-Somosierra, Sur-Occidental and Vegas, which consists of two parts: a description of the climatology and another about the distribution of the area under fallow and arable crops. It makes a bibliographic compilation of the most representative crop growth simulation models (CERES and Cereal YES), as well as trials carried out with rye and triticale crops for biomass production and studies conducted by GIS tools and techniques multicriteria analysis for the location of bioelectricity centrals and the study of the logistics of biomass. Is proposed a biomass productivity simulation model for rye and triticale for MC that results from the combination of grain production model based on climatological data and the average relative biomass/grain of both crops obtained in a prior experience. The models obtained correspond to the following equations (where TN = normalized average temperature and PN = normalized accumulated precipitation): - Production rye biomass (t d.m./ha) = 2.785 * [1.078 * ln (TN + 2*PN) + 2.3256] - Production triticale biomass (t d.m./ha) = 2,595 * [2.4495 * ln (TN + 2*PN) + 2.6103] Subsequently, applying the developed models, the biomass potential of the MC agricultural regions is quantified in each of the scenarios established, which are considered as the use of dry fallow area available (25%, 50%, 75 % and 100%). The potential biomass production that can be achieved within the MC using 100% of the rainfed fallow area based on rye and triticale crops, were estimated at 169.710,72 - 149.811,59 - 140.217,54 - 101.583,01 - 26.961,88 and 1.886,40 t annual for the regions of Campiña, Vegas, Sur Occidental, Area Metropolitana, Lozoya- Somosierra and Guadarrama, respectively. A multicriteria analysis is performed, based on compromise programming to define the agricultural regions with better features for the location of bioelectricity centrals, on the basis of biomass potential, electrical infrastructure, road network, protected areas and urban area criteria. Upon multicriteria analysis, is obtained the following hierarchical order based on criteria: Campiña, Sur Occidental, Vegas, Area Metropolitana, Lozoya-Somosierra and Guadarrama. Likewise, through the use of GIS techniques, the most suitable location for a 2,2 MW bioelectricity plant is studied in each of the agricultural regions and according to the use of dry fallow area available (25%, 50% , 75% and 100%), if there is sufficient potential. In the case of biomass rye and triticale dry basis is considered a PCI of 3500 kcal/kg, so it will take at least 17,298.28 t to satisfy the needs of each plant. Is analyzed the maximum bioelectricity potential on each of the agricultural regions on the basis of the rye and triticale crops as biomass producers. As deemed 25% or 100% dry fallow for biomass, the maximum bioelectricity potential varies between 5,4 and 21,58 MW in the Campiña region, between 4,76 and 19,05 MW in the Vegas region, between 4,46 and 17,83 MW in the Sur Occidental region, between 3,23 and 12,92 MW in the Area Metropolitana region, between 0,86 and 3,43 MW in the Lozoya-Somosierra region and between 0,06 and 0,24 MW in the Guadarrama region. The total power that could be installed in the CM from rye and triticale biomass could vary between 18.76 and 75.06 MW if is used the 25% or 100% of fallow land for rainfed crop.

Enhancing QA systems with complex temporal question processing capabilities

This paper presents a multilayered architecture that enhances the capabilities of current QA systems and allows different types of complex questions or queries to be processed. The answers to these questions need to be gathered from factual information scattered throughout different documents. Specifically, we designed a specialized layer to process the different types of temporal questions. Complex temporal questions are first decomposed into simple questions, according to the temporal relations expressed in the original question. In the same way, the answers to the resulting simple questions are recomposed, fulfilling the temporal restrictions of the original complex question. A novel aspect of this approach resides in the decomposition which uses a minimal quantity of resources, with the final aim of obtaining a portable platform that is easily extensible to other languages. In this paper we also present a methodology for evaluation of the decomposition of the questions as well as the ability of the implemented temporal layer to perform at a multilingual level. The temporal layer was first performed for English, then evaluated and compared with: a) a general purpose QA system (F-measure 65.47% for QA plus English temporal layer vs. 38.01% for the general QA system), and b) a well-known QA system. Much better results were obtained for temporal questions with the multilayered system. This system was therefore extended to Spanish and very good results were again obtained in the evaluation (F-measure 40.36% for QA plus Spanish temporal layer vs. 22.94% for the general QA system).

The comparison of maximal and endurance strength of quadriceps femori in trained and untrained elderly

The purpose of this study was to examine the differences in knee extensor maximal and endurance strength in elderly. Sixteen healthy elderly served as subjects, eight of them trained , age 61.0±8.9 yrs; height, 170.6±6.8 cm; weight, 71.8±11.7 kg [mean ± standard deviation] and eight untrained 61.4±8.1 yrs, height 174.6±7.4 cm; weight 83.9 ±14.2 kg. Maximal strength in single leg extension exercise was measured unilaterally with the dominant leg until the subjects reached their 1 Repetition Maximum (RM) covering the full Range of Motion (ROM). Muscular endurance was obtained with a load of 75% of 1-RM for 3 consecutive sets, with 2 min rest periods till failure. Load at 1 RM was lower in absolute terms in untrained, but not significant, while the relative 1-RM test was significantly lower in untrained subjects (0.20 vs. 0.25 kg load/kg body weight) (p<0.05). The number of repetitions and amount of weight lifted performed of all 3 sets was higher in trained subjects, but not significant. In the trained group both repetitions and the load managed in the third set was significant lower compared with the first two sets. The result that maximal force output is more affected compared to muscular endurance in these subjects might be due to the habitual use of quadriceps femoris muscles during activity of daily living in both trained and untrained elderly.

Unifying the observational diversity of isolated neutron stars via magneto-thermal evolution models

Observations of magnetars and some of the high magnetic field pulsars have shown that their thermal luminosity is systematically higher than that of classical radio-pulsars, thus confirming the idea that magnetic fields are involved in their X-ray emission. Here we present the results of 2D simulations of the fully coupled evolution of temperature and magnetic field in neutron stars, including the state-of-the-art kinetic coefficients and, for the first time, the important effect of the Hall term. After gathering and thoroughly re-analysing in a consistent way all the best available data on isolated, thermally emitting neutron stars, we compare our theoretical models to a data sample of 40 sources. We find that our evolutionary models can explain the phenomenological diversity of magnetars, high-B radio-pulsars, and isolated nearby neutron stars by only varying their initial magnetic field, mass and envelope composition. Nearly all sources appear to follow the expectations of the standard theoretical models. Finally, we discuss the expected outburst rates and the evolutionary links between different classes. Our results constitute a major step towards the grand unification of the isolated neutron star zoo.

The outburst decay of the low magnetic field magnetar SGR 0418+5729

We report on the long-term X-ray monitoring of the outburst decay of the low magnetic field magnetar SGR 0418+5729 using all the available X-ray data obtained with RXTE, Swift, Chandra, and XMM-Newton observations from the discovery of the source in 2009 June up to 2012 August. The timing analysis allowed us to obtain the first measurement of the period derivative of SGR 0418+5729: ˙ P = 4(1) × 10−15 s s−1, significant at a ∼3.5σ confidence level. This leads to a surface dipolar magnetic field of Bdip 6 × 1012 G. This measurement confirms SGR 0418+5729 as the lowest magnetic field magnetar. Following the flux and spectral evolution from the beginning of the outburst up to ∼1200 days, we observe a gradual cooling of the tiny hot spot responsible for the X-ray emission, from a temperature of ∼0.9 to 0.3 keV. Simultaneously, the X-ray flux decreased by about three orders of magnitude: from about 1.4 × 10−11 to 1.2 × 10−14 erg s−1 cm−2. Deep radio, millimeter, optical, and gamma-ray observations did not detect the source counterpart, implying stringent limits on its multi-band emission, as well as constraints on the presence of a fossil disk. By modeling the magneto-thermal secular evolution of SGR 0418+5729, we infer a realistic age of ∼550 kyr, and a dipolar magnetic field at birth of ∼1014 G. The outburst characteristics suggest the presence of a thin twisted bundle with a small heated spot at its base. The bundle untwisted in the first few months following the outburst, while the hot spot decreases in temperature and size. We estimate the outburst rate of low magnetic field magnetars to be about one per year per galaxy, and we briefly discuss the consequences of such a result in several other astrophysical contexts.

A strongly magnetized pulsar within the grasp of the milky way’s supermassive black hole

The center of our Galaxy hosts a supermassive black hole, Sagittarius (Sgr) A∗. Young, massive stars within 0.5 pc of Sgr A∗ are evidence of an episode of intense star formation near the black hole a few million years ago, which might have left behind a young neutron star traveling deep into Sgr A∗’s gravitational potential. On 2013 April 25, a short X-ray burst was observed from the direction of the Galactic center. With a series of observations with the Chandra and the Swift satellites, we pinpoint the associated magnetar at an angular distance of 2.4±0.3 arcsec from Sgr A∗, and refine the source spin period and its derivative (P = 3.7635537(2) s and ˙ P = 6.61(4) × 10−12 s s−1), confirmed by quasi simultaneous radio observations performed with the Green Bank Telescope and Parkes Radio Telescope, which also constrain a dispersion measure of DM = 1750 ± 50 pc cm−3, the highest ever observed for a radio pulsar. We have found that this X-ray source is a young magnetar at ≈0.07–2 pc from Sgr A∗. Simulations of its possible motion around Sgr A∗ show that it is likely (∼90% probability) in a bound orbit around the black hole. The radiation front produced by the past activity from the magnetar passing through the molecular clouds surrounding the Galactic center region might be responsible for a large fraction of the light echoes observed in the Fe fluorescence features.

The imprint of the crustal magnetic field on the thermal spectra and pulse profiles of isolated neutron stars

Isolated neutron stars (NSs) show a bewildering variety of astrophysical manifestations, presumably shaped by the magnetic field strength and topology at birth. Here, using state-of-the-art calculations of the coupled magnetic and thermal evolution of NSs, we compute the thermal spectra and pulse profiles expected for a variety of initial magnetic field configurations. In particular, we contrast models with purely poloidal magnetic fields to models dominated by a strong internal toroidal component. We find that, while the former displays double-peaked profiles and very low pulsed fractions, in the latter, the anisotropy in the surface temperature produced by the toroidal field often results in a single pulse profile, with pulsed fractions that can exceed the 50–60 per cent level even for perfectly isotropic local emission. We further use our theoretical results to generate simulated ‘observed’ spectra, and show that blackbody (BB) fits result in inferred radii that can be significantly smaller than the actual NS radius, even as low as ∼1–2 km for old NSs with strong internal toroidal fields and a high absorption column density along their line of sight. We compute the size of the inferred BB radius for a few representative magnetic field configurations, NS ages and magnitudes of the column density. Our theoretical results are of direct relevance to the interpretation of X-ray observations of isolated NSs, as well as to the constraints on the equation of state of dense matter through radius measurements.
