description: Human and civil rights organizations have long used litigation in an attempt to advance a particular cause, to bolster a certain right, or to bring about social change. A prominent example is strategic litigation filed on behalf of minority groups–including national and indigenous minorities. Such cases typically seek remedies from the government or public institutions due to discrimination or neglect experienced by minorities, or stemming from limitations on their ability to express or enjoy their culture and practices. In many cases, however, litigation fails or only partially succeeds in creating the kind of sustainable, widespread, and group-based change that the petitioners seek. Focusing on Israel and the Palestinian-Arab minority, which constitutes nearly one-fifth of the country's population, this Article explores the limitations and shortcomings of litigation as a strategy for obtaining collective rights. The Article examines three different kinds of collective rights that Palestinian-Arab petitioners have attempted to achieve through legal action in Israel: the right to political representation (in decision-making bodies); linguistic rights (in public accommodation); and equitable (group-based) allocation of public resources. The significance of these rights for national minorities is explored, along with the specifics of each of the cases highlighted and their outcomes. This Article demonstrates that while the outcome of each legal case was a ‘success’–on a technical level–the judgments failed to achieve the substantive equality and group-based rights that the petitioners sought. Worse still, some of the judgments actually may have led to setbacks. Accordingly, this article argues that litigation has thus far been an insufficient tool for protecting the collective rights of the Palestinian-Arab minority, as the courts have failed to draft meaningful and sustainable frameworks for action and enforcement into their judgments. The article concludes by suggesting that given the challenges and political and social constraints faced by national minorities in legal and other public spheres, the law is dependent on the will of the courts. Thus, the courts must view their role more broadly and take a more expansive–and perhaps even activist–approach in rendering its rulings.

description: The aim of this article is to present different images of mothers in selected Chinese contemporary literature, such as: Snow flower and the secret fan, Peony in Love, The Concubine’s Daughter, and Pearl of China. In these novels, China is portrayed as a country of privileges for men and sanctions against women. Since childhood, women had been prepared for the role of submissive wives and mothers of male heirs. This article discusses the strength, energy, and great spiritual power of women-mothers – which contrary to the cultural limitations – enabled their female descendants to believe in their own value. Several images of mothers have been portrayed: (1) mother radically obeying traditions, (2) a sensitive mother, (3) a friendly mother, and (4) a heroic mother. This paper claims that daughters, through their stories, paid homage to their mothers who risked their lives and livelihood in the patriarchal culture of China.

X-Ray and Gamma-Ray Polarization in Leptonic and Hadronic Jet Models of Blazars

description: We present a theoretical analysis of the expected X-ray and gamma-ray polarization signatures resulting from synchrotron self-Compton emission in leptonic models, compared to the polarization signatures from proton synchrotron and cascade synchrotron emission in hadronic models for blazars. Source parameters resulting from detailed spectral-energy-distribution modeling are used to calculate photon-energy-dependent upper limits on the degree of polarization, assuming a perfectly organized, mono-directional magnetic field. In low-synchrotron-peaked blazars, hadronic models exhibit substantially higher maximum degrees of X-ray and gamma-ray polarization than leptonic models, which may be within reach for existing X-ray and gamma-ray polarimeters. In high-synchrotron-peaked blazars (with electron-synchrotron-dominated X-ray emission), leptonic and hadronic models predict the same degree of X-ray polarization, but substantially higher maximum gamma-ray polarization in hadronic models than leptonic ones. These predictions are particularly relevant in view of the new generation of balloon-borne X-ray polarimeters (and possibly GEMS, if revived), and the ability of Fermi-LAT to measure gamma-ray polarization at < 200 MeV. We suggest observational strategies combining optical, X-ray, gamma-ray polarimetry to determine the degree of ordering of the magnetic field and to distinguish between leptonic and hadronic high-energy emission.

Orbital magnetization of insulating perovskite transition-metal oxides with the net ferromagnetic moment in the ground state

description: Modern theory of the orbital magnetization is applied to the series of insulating perovskite transition metal oxides (orthorhombic YTiO$_3$, LaMnO$_3$, and YVO$_3$, as well as monoclinic YVO$_3$), carrying a net ferromagnetic (FM) moment in the ground state. For these purposes, we use an effective Hubbard-type model, derived from the first-principles electronic-structure calculations and describing the behavior of magnetically active states near the Fermi level. The solution of this model in the mean-field Hartree-Fock approximation with the relativistic spin-orbit coupling typically gives us a distribution of the local orbital magnetic moments, which are related to the site-diagonal part of the density matrix $\hat{\cal D}$ by the "standard" expression $\boldsymbolμ^0 = - μ_{\rm B} \mathrm{Tr} \{ \hat{\textbf{L}} \hat{\cal D} \}$ and which are usually well quenched by the crystal field. In this work, we evaluate "itinerant" corrections $Δ\boldsymbol{\cal M}$ to the net FM moment, suggested by the modern theory. We show that these corrections are small and in most cases can be neglected. Nevertheless, the most interesting aspect of our analysis is that, even for these compounds, which are typically regarded as normal Mott insulators, the "itinerant" corrections reveal a strong $\textbf{k}$-dependence in the reciprocal space, following the behavior of Chern invariants. Therefore, the small value of $Δ\boldsymbol{\cal M}$ is the result of strong cancelation of relatively large contributions, coming from different parts of the Brillouin zone. We discuss details as well as possible implications of this cancelation, which depends on the crystal structure as well as the type of the magnetic ground state.

description: Penguins huddling in a cold wind are represented by a two-dimensional, continuum model. The huddle boundary evolves due to heat loss to the huddle exterior and through the reorganisation of penguins as they seek to regulate their heat production within the huddle. These two heat transfer mechanisms, along with area, or penguin number, conservation, gives a free boundary problem whose dynamics depend on both the dynamics interior and exterior to the huddle. Assuming the huddle shape evolves slowly compared to the advective timescale of the exterior wind, the interior temperature is governed by a Poisson equation and the exterior temperature by the steady advection-diffusion equation. The exterior, advective wind velocity is the gradient of a harmonic, scalar field. The conformal invariance of the exterior governing equations is used to convert the system to a Polubarinova-Galin type equation, with forcing depending on both the interior and exterior temperature gradients at the huddle boundary. The interior Poisson equation is not conformally invariant, so the interior temperature gradient is found numerically using a combined adaptive Antoulas-Anderson and least squares algorithm. The results show that, irrespective of the starting shape, penguin huddles evolve into an egg-like steady shape. This shape is dependent on the wind strength, parameterised by the Péclet number Pe, and a parameter \b{eta} which effectively measures the strength of the interior self-generation of heat by the penguins. The numerical method developed is applicable to a further five free boundary problems.

We focus on the methodology of this approach by emphasizing the strategy of the potential method, the theoretical foundation behind it, and special numerical techniques. We compare the potential method with the standard finite volume method in lattice QCD, in order to make pros and cons of the approach clear. We also present several numerical results for the nucleon-nucleon potentials.

description: This paper examines the former location-based social medium Brightkite, over its three-year life span, based on the concept of natural cities. The term 'natural cities' refers to spatially clustered geographic events, such as the agglomerated patches aggregated from individual social media users' locations. We applied the head/tail division rule to derive natural cities, based on the fact that there are far more low-density locations than high-density locations on the earth surface. More specifically, we generated a triangulated irregular network, made up of individual unique user locations, and then categorized small triangles (smaller than an average) as natural cities for the United States (mainland) on a monthly basis. The concept of natural cities provides a powerful means to develop new insights into the evolution of real cities, because there are virtually no data available to track the history of cities across their entire life spans and at very fine spatial and temporal scales. Therefore, natural cities can act as a good proxy of real cities, in the sense of understanding underlying interactions, at a global level, rather than of predicting cities, at an individual level. Apart from the data produced and the contributed methods, we established new insights into the structure and dynamics of natural cities, e.g., the idea that natural cities evolve in nonlinear manners at both spatial and temporal dimensions.

Evolution and Structure in Flamenco Harmony

description: This article addresses certain aspects of the development and present form of flamenco harmony. In brief, it advances two hypotheses: first, that flamenco harmony is a syncretic product of Arab modal practice and European harmony, and second, that many of the most distinctive features of the harmonic system, and in particular the use of altered chords, have arisen in direct connection with idiosyncratic characteristics of the guitar. The first of these theses, although difficult to document, is hardly original, and indeed, is widely taken for granted among flamenco scholars.

description: Today’s students live in an era that dominant social voices declare to be a “post-racial society.” Issues of “discrimination,” it follows, are simply isolated incidents easily addressed by the panoply of existing civil rights laws. This belief creates expectations on the part of first-year law students who may dismiss or ignore the existence of structural racism, sexism, and classism. The law not only creates structures of subordination, it also makes them invisible. Revelation of the subordinating effects of legal rules is an important first step in legal education. The apparent neutrality of contract law in particular masks the distributive effects of legal rules. Contract is an area of private ordering, but it is courts that invalidate or legitimize the use or allocation of power between or among parties to a contract. Unspoken assumptions about power—who has it, who may use it, and how it may be used—are embedded in contract law and theory. These assumptions may conceal bias, stereotypes, and cultural preferences in a court’s final decision. An analysis that presumes neutrality on the part of the court and autonomy on the part of the parties overlooks the various advantages and handicaps that people bring with them to each transaction, some of which may be the result of the social identity of the parties. A “neutral” free market system tolerates certain pockets of discrimination in contracting which are, in turn, endorsed by the law in the name of freedom of contract. This article addresses the importance of incorporating such discussions about identity in the first year core curriculum. It offers specific materials and techniques for doing this in a contracts class, with emphasis on the necessity and the value of grounding theoretical analysis squarely in the instruction students receive in legal reasoning. The article proposes that issues of identity should be incorporated into the classroom not only when the parties in the cases are people of color, and not simply as a politically correct exercise, but pervasively throughout the semester as a way of advancing students’ legal reasoning skills and understanding of legal doctrine. This approach should improve the law school experience for most students and produce lawyers who are more capable of practicing law holistically.

description: Fossil fuels have shaped the European economy since the industrial revolution. In this paper, we analyse the effect of coal and oil on long-run economic growth, exploiting variation at the level of European NUTS-2 and NUTS-3 regions over the last century. We show that an “oil invasion” in the early 1960s turned regional coal abundance from a blessing into a curse, using new detailed data on carboniferous strata as an instrument. Moreover, we show that human capital accumulation was the key mechanism behind this reversal of fortune. Not only did former coal regions fail to accumulate sufficient levels of human capital, but pre-industrial human capital helped declining regions to reinvent themselves. Without sufficient human capital, fossil fuels did never generate sustainable growth.

Music--Instruction and study

description: One of the most interesting social and educational institutions of nineteenth-century rural America was the singing school. Singing schools were usually held in churches, and the great bulk of the music used was sacred in text. Many of the nineteenth-century tunebooks used a system of "shape-note" notation which was invented late in the eighteenth century and first used in William Little and William Smith's The Easy Instructor (1801). The nineteenth-century rural singing masters were a humble lot, the kind of men who seldom made headlines. Among these early singing masters was a Tennessean named Alexander Johnson, compiler of the tunebook Tennessee Harmony. Johnson was the first southern shape-note tunebook compiler outside the Shenandoah Valley of Virginia. Johnson's Tennessee Harmony seems to have found an immediate and widespread acceptance in the rural sections of Middle and West Tennessee. Alexander Johnson's tunebook may not have been as widely influential in the development and dissemination of shape-note hymnody as were those by Davisson, Carden, and later compilers, but it did provide the people of MiddIe and West Tennessee with the music they wanted to sing. In addition, Johnson introduced a number of tunes into the shape-note repertoire, some of which quickly became part of the standard stock of melodies used in later books.

description: We present a microscopic theory of the optical properties of self-assembled quantum dots doped with a single magnetic manganese (Mn) impurity and containing a controlled number of electrons. The single-particle electron and heavy-hole electronic shells are described by two-dimensional harmonic oscillators. The electron-electron, electron-hole Coulomb as well as the short-range electron spin-Mn spin and hole spin-Mn spin contact exchange interactions are included. The electronic states of the photo-excited electron-hole-Mn complex and of the final electron-Mn complex are expanded in a finite number of configurations and the full interacting Hamiltonian is diagonalized numerically. The emission spectrum is predicted as a function of photon energy for a given number of electrons and different number of confined electronic quantum dot shells. We show how emission spectra allow to identify the number of electronic shells, the number of electrons populating these shells and, most importantly, their spin. We show that electrons not interacting directly with the spin of Mn ion do so via electron-electron interactions. This indirect interaction is a strong effect even when Mn impurity is away from the quantum dot center.

description: We present a magnetic-field surface map for both stellar components of the young visual binary ksi Boo AB (A: G8V, B: K5V). Employed are high resolution Stokes-V spectra obtained with the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT). Stokes V line profiles are inverted with our iMAP software and compared to previous inversions. We employed an iterative regularization scheme without the need of a penalty function and incorporated a three-component description of the surface magnetic-field vector. The spectral resolution of our data is 130,000 (0.040-0.055A) and have signal-to-noise ratios (S/N) of up to three thousand per pixel depending on wavelength. A singular-value decomposition (SVD) of a total of 1811 spectral lines is employed for averaging Stokes-V profiles. Our mapping is accompanied by a residual bootstrap error analysis. Magnetic flux densities of the radial field component of up to plus/minus 115 +/- 5 G were reconstructed for ksi Boo A while up to plus/minus 55 +/- 3G were reconstructed for ksi Boo B. ksi Boo A's magnetic morphology is characterized by a very high latitude, nearly polar, spot of negative polarity and three low-to-mid latitude spots of positive polarity while ksi Boo B's morphology is characterized by four low-to-mid latitude spots of mixed polarity. No polar magnetic field is reconstructed for the cooler ksi Boo B star. Both our maps are dominated by the radial field component, containing 86 and 89 percent of the magnetic energy of ksi Boo A and B, respectively. We found only weak azimuthal and meridional field densities on both stars (plus/minus 15-30 G), about a factor two weaker than what was seen previously for ksi Boo A. The phase averaged longitudinal field component and dispersion is +4.5 +/- 1.5G for ksi Boo A and -5.0 +/- 3.0 G for ksi Boo B.

description: Background: The paper focuses on the problem of the effect of dance as a part of movement activities on human emotions and their experiencing in students. The movement activity has a positive impact not only on physical health of a human being, but also on his mental health. Movement not only serves to increase physical fitness in healthy subjects, physical activities suitably chosen can be applied in an effective way in with weakened organ systems. The movement is nowadays considered a suitable tool to eliminate excessive stress. Research results: The study summarises our research results of positive effect of dance on experiencing emotions of students that were verified and supported by medical practice that claims positive effect of movement on mental health of an individual. Our research results indicate that respondents from dance group experienced more positive emotions than the respondents from movement group. A statistically significant difference was found at the level of significance (p = 0.0425) in the respondents from dance group (Me = 16). Their frequency of experiencing positive emotions is statistically higher than in the respondents from movement group (Me = 13).

description: We experimentally and theoretically investigate the behavior of Leidenfrost droplets inserted in a Hele-Shaw cell. As a result of the confinement from the two surfaces, the droplet has the shape of a flattened disc and is thermally isolated from the surface by the two evaporating vapor layers. An analysis of the evaporation rate using simple scaling arguments is in agreement with the experimental results. Using the lubrication approximation we numerically determine the shape of the droplets as a function of its radius. We furthermore find that the droplet width tends to zero at its center when the radius reaches a critical value. This prediction is corroborated experimentally by the direct observation of the sudden transition from a flattened disc into an expending torus. Below this critical size, the droplets are also displaying capillary azimuthal oscillating modes reminiscent of a hydrodynamic instability.

description: In this study, we analyze the Genetic Analysis Workshop 18 (GAW18) data to identify regions of single-nucleotide polymorphisms (SNPs), which significantly influence hypertension status among individuals. We have studied the marginal impact of these regions on disease status in the past, but we extend the method to deal with environmental factors present in data collected over several exam periods. We consider the respective interactions between such traits as smoking status and age with the genetic information and hope to augment those genetic regions deemed influential marginally with those that contribute via an interactive effect. In particular, we focus only on rare variants and apply a procedure to combine signal among rare variants in a number of "fixed bins" along the chromosome. We extend the procedure in Agne et al to incorporate environmental factors by dichotomizing subjects via traits such as smoking status and age, running the marginal procedure among each respective category (i.e., smokers or nonsmokers), and then combining their scores into a score for interaction. To avoid overlap of subjects, we examine each exam period individually. Out of a possible 629 fixed-bin regions in chromosome 3, we observe that 11 show up in multiple exam periods for gene-smoking score. Fifteen regions exhibit significance for multiple exam periods for gene-age score, with 4 regions deemed significant for all 3 exam periods. The procedure pinpoints SNPs in 8 "answer" genes, with 5 of these showing up as significant in multiple testing schemes (Gene-Smoking, Gene-Age for Exams 1, 2, and 3).

description: Metamaterials are nano-engineered media with designed properties beyond those available in nature with applications in all aspects of materials science. In particular, metamaterials have shown promise for next generation of optical materials with electromagnetic responses that cannot be obtained from conventional media. We review the fundamental properties of metamaterials with hyperbolic dispersion and present the various applications where such media offer potential for transformative impact. These artificial materials support unique bulk electromagnetic states which can tailor light-matter interaction at the nanoscale. We present a unified view of current research in the field of hyperbolic metamaterials such as sub-wavelength imaging and broadband photonic density of states engineering. The review introduces the concepts central to the theory of hyperbolic media as well as nanofabrication and characterization details essential to experimentalists. Finally, we outline the challenges in the area and offer a set of directions for future work.

description: Vom Verlagssystem des frühen 19. Jahrhunderts bis hin zu den Qualitätszirkeln der Gegenwart haben die Marktwirtschaften versdiiedene organisatorische Lösungen für das Problem der Verteilung und Entlohnung von Arbeit gekannt. Die Vielfalt solcher Arrangements ist nahezu unerschöpflich: Sie reichen vom selbständigen Sub- unternehmer in den Fabriken um die Jahrhundertwende über tayloristische Systeme der „wissenschaftlichen" Verteilung und Entlohnung von Handarbeit, die bürokra- tisierten Regeln hinsichtlich Aufstieg und Arbeitsentgeltung durch interne Arbeits- märkte, das japanische System der flexiblen Arbeitsneuverteilung, die unternehme- rischen Einheiten innerhalb des Unternehmens bei Hewlett-Packard bis hin zu der autonomen Gruppenarbeit in der skandinavischen Automobilindustrie, in der das Fließband abgeschafft wurde. Aber auch die zentral gelenkten Wirtschaftssysteme haben in den vergangenen siebzig Jahren verschiedene Organisationsformen der Verteilung und Entlohnung von Arbeit gekannt. Zu nennen wären hier beispiels- weise Trotzkys militarisierte Programme in der Zeit des Kriegskommunismus, die wiederholten Versuche zur Einführung des Taylorismus, die Stakhanovitenbewe- gung, die Zulassung des Wettbewerbs unter sozialistischen Brigaden, die zentral festgesetzten Lohngruppen und Lohnregelungen sowie das unlängst in den Land- wirtschaftskommunen Chinas eingeführte „System der familialen Verantwortlich- keit".

description: In the absence of environmental cues, a migrating cell performs an isotropic random motion. Recently, the breaking of this isotropy has been observed when cells move in the presence of asymmetric adhesive patterns. However, up to now the mechanisms at work to direct cell migration in such environments remain unknown. Here, we show that a non-adhesive surface with asymmetric micro-geometry consisting of dense arrays of tilted micro-pillars can direct cell motion. Our analysis reveals that most features of cell trajectories, including the bias, can be reproduced by a simple model of active Brownian particle in a ratchet potential, which we suggest originates from a generic elastic interaction of the cell body with the environment. The observed guiding effect, independent of adhesion, is therefore robust and could be used to direct cell migration both in vitro and in vivo.

description: In various types of many-particle systems, bidispersity is frequently used to avoid spontaneous ordering in particle configuration. In this study, the relation between bidispersity and disorder degree of particle configuration is investigated. By using magnetic dipole-dipole interaction, magnet particles are dispersed in a two-dimensional cell without physical contact between them. In this magnetic system, bidispersity is introduced by mixing large and small magnets. Then, the particle system is compressed to produce a uniform particle configuration. The compressed particle configuration is analyzed by using Voronoi tessellation for evaluating the disorder degree which strongly depends on bidispersity. Specifically, standard deviation and skewness of the Voronoi cell area distribution are measured. As a result, we find that the peak of standard deviation is observed when the numbers of large and small particles are almost identical. Although the skewness shows non-monotonic behavior, zero skewness state (symmetric distribution) can be achieved when the numbers of large and small particles are identical. In this ideally random (disordered) state, the ratio between pentagonal, hexagonal, and heptagonal Voronoi cells become roughly identical, while hexagons are dominant in monodisperse (ordered) condition. The relation between Voronoi cell analysis and the global bond orientational order parameter is also discussed.
