Dynamics around Non-Spherical Symmetric Bodies: I. The case of a spherical body with mass anomaly

The space missions designed to visit small bodies of the Solar System boosted the study of the dynamics around non-spherical bodies. In this vein, we study the dynamics around a class of objects classified by us as Non-Spherical Symmetric Bodies, including contact binaries, triaxial ellipsoids, spherical bodies with a mass anomaly, among others. In the current work, we address the results for a body with a mass anomaly. We apply the pendulum model to obtain the width of the spin-orbit resonances raised by non-asymmetric gravitational terms of the central object. The Poincaré surface of section technique is adopted to confront our analytical results and to study the system’s dynamics by varying the parameters of the central object. We verify the existence of two distinct regions around an object with a mass anomaly: a chaotic inner region that extends beyond the corotation radius and a stable outer region. In the latter, we identify structures remarkably similar to those of the classical restrict and planar 3-body problem in the Poincaré surface of sections, including asymmetric periodic orbits associated with 1:1+p resonances. We apply our results to a Chariklo with a mass anomaly, obtaining that Chariklo rings are probably related to first kind periodic orbits and not with 1:3 spin-orbit resonance, as proposed in the literature. We believe that our work presents the first tools for studying mass anomaly systems.

Finding the NCCs will not solve all our problems

Subjective experience has often taken center stage in debates between competing conceptual theories of the mind. This is also a central object of concern in the empirical domain, and especially in the search for the neural correlates of consciousness (NCCs). By now, most of the competing conceptual theories of consciousness have become aligned with distinct hypotheses about the NCCs. These hypotheses are usually distinguished by reference to their proposed location of the NCCs. This difference in hypothesized location of the NCCs has tempted participants in these debates to infer that evidence indicating the location of the NCCs in one or the other brain region can be taken as direct evidence for or against a given conceptual theory of consciousness. We argue that this is an overestimation of the work finding the NCCs can do for us, and that there are principled reasons to resist this kind of inference. To show this we point out the lack of both an isomorphism and a homomorphism between the conceptual frameworks in which most theories are cached, and the kind of data we can get from neuroimaging. The upshot is that neural activation profiles are insufficient to distinguish between competing theories in the conceptual domain. We suggest two ways to go about ameliorating this issue.

Re-Actualization Balinese Gamelan Harmony for Renewal Knowlegde of the Balinese Music

Balinese music has a variety of gamelan that develops in the community. Balinese gamelan is a central object in the development of Balinese musical knowledge. One of the most problematic is the harmony system. In the context of Balinese music knowledge, the harmony system is an element that is often discussed its existence. The 'harmony system' has been recognized through the dualistic concept. This concept is the source of the technique for playing the Balinese Gamelan. Knowledge of the harmony system with this dualistic concept is based on the object of research by Gamelan Gong Kebyar. Gamelan Gong Kebyar is indeed very closely related to the dualistic system. However, this system is not relevant to several other Balinese Gamelan, one of which is the Gamelan Gambang. Therefore, knowledge of the harmony system in Balinese music needs to be updated. This update is an actualization of knowledge about gamelan harmony. The problems discussed in this article are what is Balinese Gamelan harmony, what is the roles of Balinese Gamelan harmony and the concept of Balinese musical harmony. This reaserch uses a mix method, namely qualitative and quantitative methods. Musicology approach as a qualitative method while sound physics as a quantitative method. Re-aktualisasi Harmoni Gamelan Bali untuk Pembaruan Pengetahuan Musik Bali Abstrak Karawitan Bali memiliki ragam gamelan yang berkembang di masyarakat. Gamelan Bali merupakan objek sentral dalam pengembangan pengetahuan karawitan Bali. Salah satu yang paling bermasalah adalah sistem harmoni. Dalam konteks pengetahuan karawitan Bali, sistem harmoni merupakan unsur yang sering dibicarakan keberadaannya. Sistem harmoni terepresentasi melalui konsep dualistik. Konsep inilah yang menjadi sumber teknik memainkan Gamelan Bali pada umumnya. Pengetahuan sistem harmoni dengan konsep dualistik ini berdasarkan objek penelitian Gamelan Gong Kebyar. Gamelan Gong Kebyar memang sangat erat kaitannya dengan sistem dualistik. Namun sistem ini tidak relevan dengan beberapa Gamelan Bali lainnya, salah satunya Gamelan Gambang. Oleh karena itu, pengetahuan tentang sistem harmoni dalam karawitan Bali perlu dimutakhirkan. Pembaruan ini merupakan aktualisasi pengetahuan tentang harmoni gamelan. Permasalahan yang dibahas dalam artikel ini adalah apa yang dimaksud dengan harmoni Gamelan Bali, batasan harmoni Gamelan Bali dan model harmoni secara musikal gamelan Bali. Penelitian ini menggunakan mixmethode , yaitu metode kualitatif dan kuantitatif. Pendekatan musikologi sebagai metode kualitatif sedangkan fisika bunyi sebagai metode kuantitatif.

Expanding Mechanisms of Governance: Uncertainty and Risk in Police Decision-Making Strategies in the Pursuit of Specialized Peace Bonds

This study examines police officers’ decision-making practices through analyzing how they determine which offenders are candidates for an 810, or peace bond. This legal tool allows police officers to petition the courts for continued surveillance and conditions for offenders postrelease. Little, however, is offered in terms of assessment guidelines on how to make such determinations. As a result, police officers discretionary behaviors and additional legal factors play a key role in these determinations. Our findings advance the idea that “uncertainty” is the central object to be managed, and further complicate how risk is constructed and mobilized by suggesting that risk assessments result in over-precautionary practices.

Pionirski grad u Zagrebu pedesetih godina 20. veka: laboratorija socijalističkog detinjstva

This paper attempts to underline the role that the Pioneer Town in Zagreb played in the process of establishing a new educational policy in Yugoslavia proclaimed at the Third Plenum of the Central Committee of the Communist Party of Yugoslavia in December 1949. This reform was carried out during the following decade, culminating in the General Law on Education in 1958. The Pioneer Town in Zagreb, with its elementary school as the central object, “simulated” a school of the future which was supposed to become not only a role model for the standard Yugoslav school, but also the initiator of the important social processes with the aim of placing children - one of the most numerous social groups - at the center of political and social attention.

Introduction

The original goal of socialism in Britain was to supersede “politics” and achieve a non-governmental form of collective life. This Introduction argues for approaching the period between 1817 and 1918 as a “socialist century,” demarcated, respectively, by Robert Owen’s introduction of his first socialist “Plan” and the Labour Party’s adoption of its first constitution and party program. Adopting this approach brings into view a tradition of anti-political socialist activism that spans the century. But the particular purpose of Imagining Socialism is to disclose and elucidate the role the aesthetic concepts and modalities play in subtending the heterogeneous anti-political experiments it investigates. In so doing, this study reveals unexpected commonalities between what are often treated as discontinuous and even antithetical stages of socialist activity. The Introduction also elucidates this study’s central theoretical terms and defines its central object of study by distinguishing socialism from several adjacent traditions (including liberalism, civic republicanism, and Marxian communism). Finally, it argues that socialism is best conceived as a goal to be imagined, rather than a readymade ideological program to be imposed.

Propuestas para el estudio de las imágenes en la era de la posverdad

A reflection on the role of images in the post-truth era and on the concept of image itself, which constitutes a central object of study in the field of communication sciences, is presented. The conceptual complexity –semiotic and symbolic– of the image is shown, which explains the diversity of approaches in studies on images. Then, several proposals are exposed for the study of images in the current context of disinformation. Finally, a brief reflection is developed on the need to analyse audiovisual texts in the society of spectacle and post-truth. Resumen Reflexión sobre el papel de las imágenes en la era de la posverdad y acerca del propio concepto de imagen, que constituye un objeto de estudio central en el campo de las ciencias de la comunicación. Se muestra la complejidad conceptual –semiótica y simbólica– de la imagen, que explica la diversidad de aproximaciones en los estudios sobre las imágenes. A continuación, se presentan propuestas para el estudio de las imágenes en el actual contexto de la desinformación. Finalmente, se desarrolla una breve reflexión sobre la necesidad del análisis de los textos audiovisuales en la sociedad del espectáculo y de la posverdad.

Imaging Wavefunctions

The concept of wavefunction was introduced in the first 1926 paper by Erwin Schrödinger as the central object of the atomic world and the cornerstone of quantum mechanics. It is a mathematical representation of de Broglie’s postulate that the electron is a material wave. It was defined as everywhere real, single-valued, finite, and continuously differentiable up to the second order. Nevertheless, for many decades, wavefunction has not been characterized as an observable. First, it is too small. The typical size is a small fraction of a nanometer. Second, it is too fragile. The typical bonding energy of a wavefunction is a few electron volts. The advancement of STM and AFM has made wavefunctions observable. The accuracy of position measurement is in picometers. Both STM and AFM measurements are non-destructive, which leaves the wavefunctions under observation undisturbed. Finally, the meaning of direct experimental7 observation and mapping of wavefunctions is discussed.

Bußgeldrechtliche Sanktionierung juristischer Personen im neuen Marktmissbrauchsrecht

The main cause of the financial market crisis was the lack of effective and deterrent sanctions for market abuse and the inadequate enforcement of these sanctions. The European legislator has addressed this shortcoming by massively tightening sanctions – especially fines against legal persons. The thesis examines new legal issues that arise in particular from the increasing regulatory density at the European level. The central object of investigation is the tension between the need for deterrent sanctions and the preservation of the principle of proportionality as well as other constitutional principles at the level of the individual company as well as the level of the corporate group.

Centers and Peripheries in a World of Blockchain: An Introduction to the Symposium

If, as has been claimed by one of their most successful proponents, blockchain technologies “automate away . . . center[s]” of authority, in lieu of subordinating peripheries, then what might this imply for global governance: already the work of a distributed politico-legal regime without a single center? Does blockchain seem likely to emancipate and equalize in the ways frequently anticipated? Whose authority is being “automate[d] away” and whose is being augmented by prevailing blockchain implementations? How might blockchain-borne redistribution bear upon law and legal institutions, or what might it demand of those, on the international plane? How might we envision blockchain-based futures on the global plane? These are among the questions taken up by contributors to this symposium. Before examining the various ways in which this rich suite of essays approach these and other cognate questions, the central object of their concern—blockchain—warrants brief, explanatory attention.
