Islam And Democracy

This paper reviews how the civilizational discourse of Islam differs from that of democracy but doesn't necessarily mean that it contradicts it. Knowing that this juxtaposition promotes diversity and distinction, this paper elucidates the factors of ambiguity that surround this religion and system in order to uncover the real dimension of their distinction. The paper is organized as follows: first, it presents seven characteristics of the Islamic state. Next, it discusses the importance of consultation (al-shūrā) and the necessity of questioning the rulers in Islam. Third, the article answers the question “Where does democracy correspond to Islam and where does it differ?”. Several prominent opinions are examined in the fourth part, before displaying the main positions from the 1980s, vis-à-vis democracy, in part five. Part six exhibits the fatwas of al-Qaradawi. At the end of the article, the paper emphasizes the approaches that can be taken towards Islamic ruling (sharīʿah).

Benford's Law

In Spain, the COVID-19 pandemic has impacted the various regions of the country differently. The availability of reliable and up-to-date information has proved to be fundamental for the management of this health crisis. However, especially during the first wave of the pandemic (February–August 2020), the disparity in the recording criteria and in the timing of providing these figures to the central government created controversy and confusion regarding the real dimension of the pandemic. It is therefore necessary to have objective and homogeneous criteria at the national level to guide health managers in the correct recording and evaluation of the magnitude of the pandemic. Within this context, we propose using Benford’s Law as an auditing tool to monitor the reliability of the number of daily COVID-related deaths to identify possible deviations from the expected trend.

Geometric Result

Abstract In this paper, we study the {\mathbb{Z}/2} action on the real Grassmann manifolds {G_{n}(\mathbb{R}^{2n})} and {\widetilde{G}_{n}(\mathbb{R}^{2n})} given by taking the (appropriately oriented) orthogonal complement. We completely evaluate the related {\mathbb{Z}/2} Fadell–Husseini index utilizing a novel computation of the Stiefel–Whitney classes of the wreath product of a vector bundle. These results are used to establish the following geometric result about the orthogonal shadows of a convex body: For {n=2^{a}(2b+1)} , {k=2^{a+1}-1} , a convex body C in {\mathbb{R}^{2n}} , and k real-valued functions {\alpha_{1},\ldots,\alpha_{k}} continuous on convex bodies in {\mathbb{R}^{2n}} with respect to the Hausdorff metric, there exists a subspace {V\subseteq\mathbb{R}^{2n}} such that projections of C to V and its orthogonal complement {V^{\perp}} have the same value with respect to each function {\alpha_{i}} , that is, {\alpha_{i}(p_{V}(C))=\alpha_{i}(p_{V^{\perp}}(C))} for all {1\leq i\leq k} .

The Public Health services are closest related with the human develop. The strong relation between population health and labor productivity is determining the historical economic develop and the real capability to make sustainable the economic develop. Few sectors have an extensive and strong relation with the human develop as the Public Health. The health policies may insider over the whole population and can determine which population sector can access to the health services and the real dimension from the effective demand from these services too.

Paradigma humanis dalam kajian sastra memposisikan manusia sebagai pusat. Penelitian ini mengkaji subjektivitas tokoh dan pengarang dalam semesta novel Lelaki Harimau karya Eka Kurniawan menggunakan teori subjektivitas Slavoj Zizek. Zizek memfokuskan pemikirannya pada tatanan riil dan simbolik dalam kehidupan manusia. Menurutnya, manusia mampu meraih kebebasan dan keotentikan dirinya selama ia bertindak melampaui norma-norma simbolik dan bergerak menuju dimensi riil dalam kehidupannya. Sebaliknya, manusia akan tetap terpenjara dalam dimensi simbolik, selama ia membiarkan dirinya tetap hanyut dalam kesadaran palsu ideologi. Penelitian ini menunjukkan bahwa ada upaya radikal yang dilakukan oleh tokoh utama untuk mencapai kondisi riil melalui tindakan sadis dan tak berkeprimanusiaan yang melanggar aspek normatif dalam lingkaran simbolik. Akan tetapi, peristiwa yang dihadapi oleh tokoh tersebut berlawanan dengan diri pengarang sebagai subjek. Pengarang justru tidak menunjukkan adanya upaya radikal dalam kehidupannya sehingga ia tetap berada dalam fantasi ideologis.Kata Kunci:Subjektivitas, Slavoj Zizek, Eka Kurniawan, Tindakan Radikal, Fantasi ideologis. The humanist paradigm in literature study assigns humans as the center. This research examines the subjectivity of the characters and the author in Lelaki Harimau novel by Eka Kurniawan using Slavoj Zizek's theory of subjectivity. Zizek focused his thoughts on the real and symbolic order in human life. According to him, humans are able to achieve freedom and authenticity as long as they act beyond the symbolic norms and move towards the real dimension in their life. On the contrary, humans will remain imprisoned in a symbolic dimension as long as they allowed themselves drifted away on a false consciousness of ideology. This research indicates that there are radical efforts made by the main characters to achieve the real conditions through sadistic and inhumane actions that violate the normative aspects in a symbolic circle. However, the events faced by these characters are opposite to the author as the subject. In fact, the author does not perform any radical efforts in his life so that he remains in ideological fantasies.Keywords: subjectivity, Slavoj Zizek, Eka Kurniawan, radical act, ideological fantasy

The Ideal

This volume comprises three parts. The issue of Part I is the nature of law. The main thesis is that law has a dual nature. It comprises a real as well as an ideal dimension. The real dimension is defined by authoritative issuance and social efficacy, the ideal dimension by the claim to correctness, which includes a claim to justice. This connection of the real and the ideal dimension implies non-positivism. In Part II the connection between constitutional rights, human rights, and proportionality is taken up. The construction of constitutional rights as principles is to be found at the centre. The principles construction implies the necessity of proportionality analysis and, with this, the necessity of balancing. Balancing is defended against numerous critics as a form of rational legal argumentation. Part III concerns the relation between argumentation, correctness, and law.

AbstractLet L be an oriented Lagrangian submanifold in an n-dimensional Kähler manifold M. Let u: D → M be a minimal immersion from a disk D with u(𝜕D) ⊂ L such that u(D) meets L orthogonally along u(𝜕D). Then the real dimension of the space of admissible holomorphic variations is at least n + μ(E, F), where μ(E, F) is a boundary Maslov index; the minimal disk is holomorphic if there exist n admissible holomorphic variations that are linearly independent over ℝ at some point p ∈ 𝜕D; if M = ℂPn and u intersects L positively, then u is holomorphic if it is stable, and its Morse index is at least n + μ(E, F) if u is unstable.

AbstractWe prove that the topological complexity of a quaternionic flag manifold is half of its real dimension. For the real oriented Grassmann manifolds G͠n,k, 3 ≤ k ≤ [n/2], the zero-divisor cup-length of the rational cohomology of G͠n,k is computed in terms of n and k which gives a lower bound for the topological complexity of G͠n,k, TC(G͠n,k). When k = 3, it is observed in certain cases that better lower bounds for TC(G͠n,3) are obtained using ℤ2-cohomology.

The Ideal

In laser measuring scanners, in addition to the ideal output signal, interfering signals occur. They are due to superimposition of diffracted, reflected, scattered, incident, transmitted and interfering light. The proportions between the mentioned components vary in time and also the total intensity distribution changes. Having the above in view, a close analysis of detector signal was carried out. It was proved that for certain beam parameters the intensity distribution pattern depends on the geometry of object and the real dimension of an object can be calculated by introduction of the size dependent correction.
