The Existence of President’s Authority and Responsibility in Realizing the Purpose of the State

The government protects the entire Indonesian nation and the entire Indonesian blood, promotes the general prosperity and educate the life of the nation. As a State that intended to promote the general welfare, the attachment of the function of promoting the general welfare in the welfare state raises several consequences to the implementation of government. The research used in this article is a normative research. The results show that the existence of arrangement on the President’ authority and responsibility remain regulated and guaranteed by the 1945 Constitution of the Republic of Indonesia. Hence, in realizing the States’ goal to prosper the people is depending on the morale and commitment of the President. The President’ responsibility in realizing the State’ goal in this matter Public Welfare in addition to carrying out what has been regulated by legislation, should formulate a program related to the promises at the time of the campaign as a form of commitment to the people. Based on the findings of this research, the authors suggested that for the next presidential election really pay attention to a candidate not only from physical appearance but need to track record how the commitment to the 1945 Constitution in in Realizing the Purpose of the State.

Performance Measures to Assess Resiliency and Efficiency of Transit Systems

Transit agencies are interested in assessing the short-, mid-, and long-term performance of infrastructure with the objective of enhancing resiliency and efficiency. This report addresses three distinct aspects of New Jersey’s Transit System: 1) resiliency of bridge infrastructure, 2) resiliency of public transit systems, and 3) efficiency of transit systems with an emphasis on paratransit service. This project proposed a conceptual framework to assess the performance and resiliency for bridge structures in a transit network before and after disasters utilizing structural health monitoring (SHM), finite element (FE) modeling and remote sensing using Interferometric Synthetic Aperture Radar (InSAR). The public transit systems in NY/NJ were analyzed based on their vulnerability, resiliency, and efficiency in recovery following a major natural disaster

Static and dynamic responses to hyperoxia of normal placenta across gestation with T2*-weighted sequences

OBJECTIVES: T2*-weighted sequences have been identified as non-invasive tools to study the placental oxygenation in-vivo. This study aims to investigate both static and dynamic responses to hyperoxia of the normal placenta across gestation.METHODS: We conducted a single-center prospective study including 52 uncomplicated pregnancies. Two T2*-weighted sequences were performed: T2*-relaxometry was performed before and after maternal hyperoxia. The histogram distribution of T2* values was assessed by fitting a gamma distribution as T2*~Γ(αβ). A dynamic acquisition (BOLD protocol) was also performed before and during oxygen supply, until placental oxygen saturation. The signal change over time was modeled using a sigmoid function, used to determine the intensity of enhancement (∆BOLD,%), a temporal variation coefficient (λ,min -1 , controlling the slope of the curve), and the maximal steepness (Vmax, ∆BOLD.min -1 ) of placental enhancement. RESULTS: The histogram analysis of the T2* values in normoxia showed a whole-placenta variation, with a decreasing linear trend in the mean T2* value (R= -0.83, 95% CI [-0.9, -0.71], p&lt;0.001) along with a more peaked and narrower distribution of T2* values across gestation. After maternal hyperoxia, the mean T2* ratios (mean T2* hyperoxia / mean T2* baseline ) were positively correlated with gestational age, while the other histogram parameters remained stable, suggesting a translation of the histogram towards higher values with a similar aspect. The ∆BOLD showed a non-linear increase across gestation. Conversely, the λ(min -1 ) parameter, showed an inverted trend across gestation, with a significantly weaker correlation (R = -0.33, 95% CI [-0.58, -0.02], p=0.04, R 2 = 0.1). As a combination of ∆BOLD and λ, the changes in Vmax throughout gestation were mainly influenced by the changes in ∆BOLD and resulted in a positive non-linear correlation with gestational age. CONCLUSION: Our results suggest that the decrease in the T2* placental signal over gestation does not reflect a dysfunction. The BOLD effect, representative of a free-diffusion model of oxygenation, highlights the growing differences in oxygen saturation between mother and fetus across gestation (∆BOLD), and placental permeability to oxygen (λ).

Etude comparative de l'atteinte du niveau opératoire formel par des sujets sourds profonds de naissance

This paper is based on the works of the Genevan psychologists and tries to throw a light on the problem of the attainment of the formal operational stage by subjects deaf from early life. A review of the main researches about this theme brings out contradictory results ; therefore, a new experimental investigation has been worked out. It deals with the setting of combinatory reasoning from a task in which the subject has to find out all the classes of two elements taken from a whole of x elements. The results clearly point out that deaf subjects stay fixed at a transitional stage. When faced with the task, the deaf subjects proceed empirically, but the bringing in of an experimental constraint proves that they are able to make use of a systematic strategy leading to success, by means of methodical and complete combinations. This discrepancy between their spontaneous performance and their operational ability seems to be at the root of the opposite conclusions drawn by the different searchers.S 'appuyant sur les travaux de l'Ecole de Genève, cet article tente d'élucider le problème de l'atteinte du niveau opératoire formel par des sujets atteints de surdité profonde et précoce. Une revue des principales recherches sur ce thème fait apparaître des résultats nettement contradictoires, aussi une nouvelle investigation expérimentale a-t-elle été entreprise. Celle-ci traite de la mise en place de la combinatoire mathématique à partir d'une épreuve où il s'agit de construire toutes les classes de deux éléments pris dans un ensemble de x éléments. 83 sourds âgés de 7 à 18, 11 ans et 71 entendants âgés de 7 à 10, 11 ans ont participé à l'expérience. Les résultats obtenus soulignent la très nette fixation des sujets sourds à un niveau qualifié d'intermédiaire. En présence de la tâche, les sourds procèdent généralement par tâtonnements, mais l'introduction d'une contrainte expérimentale révèle qu'ils sont capables de mobiliser une stratégie systématique conduisant à la réussite grâce à des combinaisons méthodiques et complètes. Cette discordance entre la performance spontanée et la capacité opératoire semble être à l'origine des conclusions contradictoires tirées par les différents chercheurs.Bartin Marc.
