The Ideal

A consistent picture of the state of a bacteria-carrying particle in a bactericidal atmosphere is given. The particle is referred to an ideal ternary system where two of the components are volatile and in equilibrium with their respective vapours. The ideal phase diagrams for systems with one independent variable are given, and the large deviations from the ideal of an actual system are shown from calculations using published data on salivary particle masses in the presence of bactericide vapour at various relative humidities.

AbstractMeasurements of the actual fluorine content x in the RO1−xFxFeAs-samples by wavelength-dispersive X-ray spectroscopy (WDX) reveal sample dependent discrepancies to the nominal fluorine content (initial weight). In particular for SmO1−xFxFeAs, the measured value only reached approximately half of the required value. In the lanthanum compound LaO1−xFxFeAs, we found a good agreement mainly for x>0.05, but the fluorine hardly goes into the sample for x<0.05. We used the measured fluorine content when plotting the electronic phase diagrams again and find a more consistent picture occurs as well for our samples as for comparison with the divers published data.

3D Computer Model

Spatial (three-dimensional - 3D) computer model of the T-x-y diagram of the Ag - Cu - Ni system, which is promising for the development of environmentally friendly solders, is presented. The model is constructed on the basis of published data on the binary systems forming this ternary system, the concentration projection of the liquidus surfaces, and four isothermal sections. It is shown that the phase diagram (PD) consists of 14 surfaces and 9 phase regions. The adequacy of the model is confirmed by comparing the isothermal sections and the liquidus projection.

Debates in Singapore about immigration and naturalisation policy have escalated substantially since 2008 when the government allowed an unprecedentedly large number of immigrants into the country. This essay will discuss immigration and naturalisation policy in Singapore and the tensions that have been evoked, and how these policies are a key tool in regulating the optimal composition and size of the population for the state’s imperatives. It will demonstrate that although the state has, as part of its broader economic and manpower planning policy to import labour for economic objectives, it seeks to retain only skilled labour with an exclusive form of citizenship.  Even as the Singapore state has made its form of citizenship even more exclusive by reducing the benefits that non-citizens receive, its programmes for naturalising those who make the cut to become citizens which include the recently created Singapore Citizenship Journey (SCJ) is by no means burdensome from a comparative perspective. This paper examines policy discourse and the key symbols and narratives provided at naturalisation events and demonstrates how these are used to evoke the sense of the ideal citizen among new Singaporeans.

How should a liberal democracy respond to hate groups and others that oppose the ideal of free and equal citizenship? The democratic state faces the hard choice of either protecting the rights of hate groups and allowing their views to spread, or banning their views and violating citizens' rights to freedoms of expression, association, and religion. Avoiding the familiar yet problematic responses to these issues, this book proposes a new approach called value democracy. The theory of value democracy argues that the state should protect the right to express illiberal beliefs, but the state should also engage in democratic persuasion when it speaks through its various expressive capacities: publicly criticizing, and giving reasons to reject, hate-based or other discriminatory viewpoints. Distinguishing between two kinds of state action—expressive and coercive—the book contends that public criticism of viewpoints advocating discrimination based on race, gender, or sexual orientation should be pursued through the state's expressive capacities as speaker, educator, and spender. When the state uses its expressive capacities to promote the values of free and equal citizenship, it engages in democratic persuasion. By using democratic persuasion, the state can both respect rights and counter hateful or discriminatory viewpoints. The book extends this analysis from freedom of expression to the freedoms of religion and association, and shows that value democracy can uphold the protection of these freedoms while promoting equality for all citizens.

In the Arabian Gulf two identities can be really considered almost as important as the national one: the tribal and the sectarian ones. Someone should expect that the reinforcement of these identities is a direct response to inequality and processes of exclusion. Furthermore, parochial tribalism is expected to arise as the protector of cultural heritage, especially in a region where the ex-pats vastly outnumber the locals. Nonetheless, both statements are far from truth. In this paper we will analyze how in the Gulf, sectarian identity came to play a significant role only after the 1979 Islamic revolution in Iran and it keeps on surviving through mainly instigations and Iranian propaganda, provocations and support. It should be noted that Sunni identity has been allegedly subjugated in other Middle East States (mainly in Syria and Iraq) but in the Gulf the sectarian challenge stems from the Shia communities, openly supported by Tehran. Strangely enough, the tribal identity does not pose that much of a challenge, since tribes are more the friend than the enemy of all Gulf States. Actually, these countries could not have survived without the loyalty and commitment of the tribes not only to the Royal families but also to the idea of the State and the ideal of the Nation – and Gulf Nations do protect their cultural heritage.

Studies on peasantry in medieval India 1 , particularly peasant protests in the late Mughal period, have not adequately addressed the issue of class consciousness in peasantry or that of class character of peasant protests against the state. In a way, agency has been denied to the peasantry in collectively developing and articulating an informed understanding of its distinct social position and economic interests as a class, as well as in protecting those interests. This essay retrieves this agency by arguing that the peasantry in late medieval north India, that is, late seventeenth and early eighteenth centuries ce, did develop a degree of self-consciousness as a class and that its conflict with the state did betray a certain class character. The folksongs and folktales popular among the peasantry since the medieval times have all the ingredients with which to construct a definite peasant class ideology that included conceptions of economic interest, social ethics and relation with the ruling class. On the basis of hitherto understudied Rajasthani documents, the article details the various ways in which the state intervened in the peasants’ socio-cultural and economic lives and the ways in which the peasants responded to these interventions. It also shows how the peasants’ class consciousness conditioned their engagement with the state in specific areas, whether grievance redressal, conflict resolution or agricultural production and surplus distribution. Furthermore, it discusses how caste consciousness in a stratified peasant society impinged on its class consciousness. However, there remained certain limits to the fuller development of this class consciousness, which ultimately constrained the fuller realisation of the potential of peasants’ class struggle against the state. The essay locates these limits in the peasants’ periodic negotiations with the state and their belief in the ideal of a non-conflictual, harmonious relation with the state.

The political concept of Alfarabi is derivated from the concept of Platonic, Aristotelian, and Islam. The ideal state is the state which is elaborated the universal values of humanism, not just limited to certain ethnic and nation which is emphasizing its obedience just to God, not the something else. In this paper, the writer tried to interpret the original works of Alfarabi which is directly related to his political thought and the other thinkers who are studying his political thought. In his political thought, Alfarabi emphasized that the main purpose of the state is to make the social-welfare for its citizens. Based on the organic theory, Alfarabi stated that the government of the state is just look-like the human organism system. In which, each of the existing element functioned to strengthen each other to achieve one goal. The ideal state for Alfarabi is the state which is having the goals for its citizen welfare, and who become the prime leader is a philosopher, who is having the prophetic character, having the wider knowledge, and able to communicate with al 'aql al fa’al trough al ‘aql mustafad.

<p style='text-indent:20px;'>We analyze hypotheses tests using classical results on large deviations to compare two models, each one described by a different Hölder Gibbs probability measure. One main difference to the classical hypothesis tests in Decision Theory is that here the two measures are singular with respect to each other. Among other objectives, we are interested in the decay rate of the wrong decisions probability, when the sample size <inline-formula><tex-math id="M1">\begin{document}$ n $\end{document}</tex-math></inline-formula> goes to infinity. We show a dynamical version of the Neyman-Pearson Lemma displaying the ideal test within a certain class of similar tests. This test becomes exponentially better, compared to other alternative tests, when the sample size goes to infinity. We are able to present the explicit exponential decay rate. We also consider both, the Min-Max and a certain type of Bayesian hypotheses tests. We shall consider these tests in the log likelihood framework by using several tools of Thermodynamic Formalism. Versions of the Stein's Lemma and Chernoff's information are also presented.</p>

The Ideal

All empirical water column correction methods have consistently been reported to require existing depth sounding data for the purpose of calibrating a simple depth retrieval model; they yield poor results over very bright or very dark bottoms. In contrast, we set out to (i) use only the relative radiance data in the image along with published data, and several new assumptions, (ii) in order to specify and operate the simplified radiative transfer equation (RTE), (iii) for the purpose of retrieving both the satellite derived bathymetry (SDB) and the water column corrected spectral reflectance over shallow seabeds. Sea truth regressions show that SDB depths retrieved by the method only need tide correction. Therefore it shall be demonstrated that, under such new assumptions, there is no need (i) for formal atmospheric correction, (ii) nor for conversion of relative radiance into calibrated reflectance , (iii) nor for existing depth sounding data, to specify the simplified RTE and produce both SDB and spectral water column corrected radiance ready for bottom typing. Moreover, the use of the panchromatic band for that purpose is introduced. Altogether, we named this process the Self-Calibrated Supervised Spectral Shallow-sea Modeler (4SM). This approach requires a trained practitioner, though, to produce its results within hours of downloading the raw image. The ideal raw image should be a &ldquo;near-nadir&rdquo; view, exhibit homogeneous atmosphere and water column, include some coverage of optically deep waters and bare land, and lend itself to quality removal of haze, atmospheric adjacency effect, and sun/sky glint.
