Scaling laws and universality in the choice of election candidates

Nowadays there is an increasing interest of physicists in finding regularities related to social phenomena. This interest is clearly motivated by applications that a statistical mechanical description of the human behavior may have in our society. By using this framework, we address this work to cover an open question related to elections: the choice of elections candidates (candidature process). Our analysis reveals that, apart from the social motivations, this system displays features of traditional out-of-equilibrium physical phenomena such as scale-free statistics and universality. Basically, we found a non-linear (power law) mean correspondence between the number of candidates and the size of the electorate (number of voters), and also that this choice has a multiplicative underlying process (lognormal behavior). The universality of our findings is supported by data from 16 elections from 5 countries. In addition, we show that aspects of network scale-free can be connected to this universal behavior.Comment: Accepted for publication in EP

Reactor Antineutrinos Signal all over the world

We present an updated estimate of reactor antineutrino signal all over the world, with particular attention to the sites proposed for existing and future geo-neutrino experiment. In our calculation we take into account the most updated data on Thermal Power for each nuclear plant, on reactor antineutrino spectra and on three neutrino oscillation mechanism.Comment: 4 pages including 1 figur

Pemikiran Haji Abdul Malik Karim Amrullah (Hamka) Tentang Partisipasi Politik Perempuan Di Indonesia Tahun (1949 – 1963)

Since Mary Wollstonecraft demanded equal rights for women in all fields and denounced all forms of discrimination in her book A Vindication of the Rights of Women in 1792, feminist movements began to emerge and demand the same thing, including the right to participate in politics. Indonesia, which was still called the archipelago, then had given right to women to participate in politics. The motivation of political participation of women in Indonesia was different from that of the Westerners. The motivation of the former was based on a religious spirit, not the spirit of feminism as stated by Hamka in his book Tjemburu (Ghirah). Based on this, this research focuses on Hamka's thought on Indonesian women political participation. The purpose of this study is to explore and analyze Hamka's thoughts, and construct them, and then associate them with the current Indonesian women political participation. This research is qualitative, based on library research, and done by reviewing, tracking, and analyzing data from the books and newspaper archives. This study uses historical and philosophical. The research data are derived from primary and secondary data sources. The primary data ones are divided into two: first, the primary data sources from Hamka's books that tell about women and women's political participation in general, and, second, the primary data sources from Hamka's books that specifically discuss about Indonesian women's political participation. Analysis of data uses deductive and reflective methods. Based on the results of this research, we can conclude that Hamka had underlined his political thought construction by making the divine revelation as the supreme law. Hamka strengthened the construction of his thought on women's political participation with the element of unity of I'tiqad. This I'tiqad unity was not only in women but also in men, so that they could work together to build a religious Muslim community. Hamka himself basically allowed women (especially a muslim woman) to participate in politics as long as they had religious understanding, knowledge, and high Islamic morale, did not forget their main tasks as wives and mothers, were critical, and dare. Then it could be found as well, the two types of Indonesian women's political participation Hamka's thought, they were based on motivation and activities

Geoneutrinos and reactor antineutrinos at SNO+

In the heart of the Creighton Mine near Sudbury (Canada), the SNO+ detector is foreseen to observe almost in equal proportion electron antineutrinos produced by U and Th in the Earth and by nuclear reactors. SNO+ will be the first long baseline experiment to measure a reactor signal dominated by CANDU cores ($\sim$55\% of the total reactor signal), which generally burn natural uranium. Approximately 18\% of the total geoneutrino signal is generated by the U and Th present in the rocks of the Huronian Supergroup-Sudbury Basin: the 60\% uncertainty on the signal produced by this lithologic unit plays a crucial role on the discrimination power on the mantle signal as well as on the geoneutrino spectral shape reconstruction, which can in principle provide a direct measurement of the Th/U ratio in the Earth.Comment: 7 pages including 2 figures and 1 table, in XIV International Conference on Topics in Astroparticle and Underground Physics (TAUP 2015) IOP Publishing , published on Journal of Physics: Conference Series 718 (2016) 06200

An observational study of children interacting with an augmented story book

We present findings of an observational study investigating how young children interact with augmented reality story books. Children aged between 6 and 7 read and interacted with one of two story books aimed at early literacy education. The books pages were augmented using animated virtual 3D characters, sound, and interactive tasks. Introducing novel media to young children requires system and story designers to consider not only technological issues but also questions arising from story design and the design of interactive sequences. We discuss findings of our study and implications regarding the implementation of augmented story books

Análise econômica de lâminas de água e doses de nitrogênio, para cultura de milho, utilizando o modelo ceres-maize.

Para a simulacao dos dados necessarios nas analises do presente trabalho, utilizou-se o modelo CERES-MAIZE, que esta inserido no pacote DSSAT 3.0. Nas simulacoes, realizadas para o municipio de Janauba - MG, utilizou-se o cultivar de milho BR-201, desenvolvido na EMBRAPA Milho e Sorgo, que ocupa entre 5 a 7% da area de plantio da cultura no Brasil. Foram simulados os dados de produtividade do cultivar BR-201, em tres epocas de plantio (15.05, 15.10 e 15.11), com ou sem irrigacao, com as seguintes laminas d'agua 4,8,12,16,20,24,30 e 36mm, aplicadas em um turno de rega de 7 dias. As laminas de agua foram combinadas com as seguintes doses de nitrogenio 0, 30, 60, 90, 120, 150, 180 e 210 kg/ha 4. Os dados foram simulados utilizando-se dados climaticos de 18 anos, de 1977 a 1995. Verifica-se que o plantio de maio proporcionou maior retorno economico, indicando grande potencialidade do modelo para estudos de analise de producao. Recomendam-se simulacoes com outros cultivares mais adaptados ao plantio irrigado
