description: India is facing a huge financial problem of unemployment and less per capita income. Many industrial unitsare facing loses and banks are getting cash deficit. In order to revive Indian economy, small and mediumbusiness enterprises and banking sector, we have to introduce a new type of financial instrument that ismultipurpose in nature. There are many types of financial instruments, government policies and schemes likeJan Dhan Yojana, Sukanya Samridhi Yojana etc but some are out dated and some have flaws in theirconditions. These flaws make them vulnerable to misuse. This paper proposes to create a new financialinstrument that will ensure greater transparency, help increase the disposable income and will also become acash cow for banking sector. The new proposed financial instrument will be issued by the bank and will becontrolled by the Ministry of Finance and will benefit customer, national economy and banks.
Fostering aesthetic response discourse through literature circles in the secondary classroom
Creators: name: Clark, Denise Lynette
Publisher: name: University of British Columbia
Year: 2009

description: Literature circles are being used in the classroom as a student-centered method to teach novel studies. There are many different approaches to literature circles that teachers may employ. This qualitative case study examines four of these approaches: Daniels' (1994) Role Sheets; Kooy and Wells' (1996) Response Journals; Post-It Notes or "stikkums" described by Simpson (1995), Samway and Whang (1997) and Paulsen (in Danieis, 1994); and the Placemat approach. The question guiding this study is which of these approaches is more effective in promoting high school students' aesthetic responses, enhancing their discussion, deepening their understanding of a text, and furthering their critical-thinking skills in terms of literary analysis. The study took place in my grade 9 English classroom where students were placed into small groups for a novel study and each group used one of the four approaches, with a fifth group trying a different approach each time they met for discussion. These discussions were tape-recorded, transcribed and then analyzed using two theoretical lenses. The first lens examined the data using Wilhelm's ten dimensions of response in order to see if all approaches promoted the same dimensions. In my second analysis, I analyze data through the lens of my own theoretical construct that is based on Barnes & Todd's (1995) exploratory and presentational talk, combined with Rosenblatt's (1995) notion of the aesthetic, lived-through response. This case study reveals that the various approaches promote different dimensions of response as well as different levels of aesthetic and efferent discourse. Not all approaches achieve Rosenblatt's (1995) aesthetic, lived-through response to literature. The implications for teachers centre around the learning outcomes they seek when implementing literature circles in their classes.

description: This paper has a two-fold goal. First, it attempts to argue that the circumfixal nature of the negative morpheme in Moroccan Arabic supports the existence of impenetrable (cyclic) domains, as in Chomsky’s (2001) Derivation by Phase. The second goal is to propose a principled account of the long-standing puzzle of the co-occurrence restriction holding between the post-verbal negative marker {-ʃ} and negative polarity items in an adjacent domain. Applying the precepts of Distributed Morphology, my proposal consists of formalizing this restriction in the form of a general constraint banning the realization of multiple negative morphemes in the same spell-out domain, with the effects being the deletion of the post-verbal negative marker. This is achieved via postulating post-syntactic morphological operations. I show that this prediction is not only borne out in MA but also cross-linguistically.

description: This paper addresses two issues that characterize the (morpho)-syntax of sentential negation in Standard Arabic (SA) and modern Arabic varieties. The first one is parametric and addresses the location of negation in the clause structure. The second issue concerns the agreement markers realized on the negative particle laysa along with the temporal interpretation that some of the negative markers in SA encode, namely lan and lam. Two views have been contrasted in the literature: the Low Neg analysis, according to which Neg is the complement of TP, and the High-Neg analysis whereby Neg is higher than T. In this study, I will argue that while the two views account for a good range of empirical facts, Low-Neg analysis lacks empirical adequacy. Similarly, the High Neg view is hard to reconcile within the Spec-head agreement and the standard Agree approach. However, I will show that the High-Neg analysis can be still maintained under the Feature-Inheritance approach,in which T inherits its ø-features and Tense feature from C.

description: This paper is a Critical Discourse Analysis of the representation of rape within the Moroccan culture. In particular, it attempts to show the constitutive role of language when it comes to people‘s (verbal) reaction to rape incidents in social networking sites, namely Facebook and YouTube. This is achieved byanalyzing the language used as a reaction to the recent attempted sexual assault incidents taking place in different areas in Morocco, with the aim being to depict the linguistic and discursive features via which gender-discriminatory ideologies are circulated and reinforced in these e-platforms. The discursive strategies analyzed show how women who are victims of rape are subjected to another subtler form of violence- verbal violence- in social media. The data gathered herein have affirmed our gendered performances, unravelling some culturally powerful definitions of social reality/practices, where women are still held responsible for men‘s sexual aggression. The implications of this study have far-reaching consequences, most important of which is that they will deepen our understanding of the structuring effects of language.

description: The present paper addresses the issue of language policy and language planning in Morocco. In particular, it argues that that there is a lack of a clear language planning strategy that is based on a sound political, socio-economic, ideological and academic justification. This problem has resulted in an inconsistent education approach, creating an incompatibility between different levels of education (e.g. high schools vs. universities), social classes (e.g. low class vs. middle/high class) and professional environments (e.g. academia vs. job market). For this reason, we suggest that three elements need to be integrated into any language planning effort. These are Literacy Prestige, Economic Prestige and Academic/Scientific Prestige.

description: In this paper, we develop a simple model of social dynamics governing the evolution of strategic self-protection choices of boundedly rational potential victims facing the threat of prospective offenders in a large population with random matching. We prove that individual (and socially transmitted) fear of exposure to criminal threats may actually condition choices even in the face of objective evidence of declining crime rates, and thereby cause the eventual selection of Pareto inefficient equilibria with self-protection. We also show that a suitable strategy of provision of public security financed through discriminatory taxation of self-protective expenses may actually overcome this problem, and drive the social dynamics toward the efficient no protection equilibrium. In our model, we do not obtain, as in Cressman et al. (1998), a crowding-out result such that the net impact of public spending on the actual social dynamics is neutral and the economy keeps on cycling between phases of high and low criminal activity with varying levels of self-protection; quite to the contrary, it can be extremely effective in implementing the social optimum, in that it acts primarily on the intangible dimension, that is, on the social dynamics of fear. We claim that this kind of result calls for more interdisciplinary research on the socio-psycho-economic determinants of fear of crime, and for consequent advances in modelling approaches and techniques.

Our focus in this work is to thoroughly document the electromagnetic response of the nodal metal state which is initiated with only few holes doped in parent antiferromagnetic systems and extends up to the pseudogap boundary in the phase diagram. The key signature of the nodal metal is the two-component conductivity: the Drude mode at low energies followed by a resonance in mid-IR. The Drude component can be attributed to the response of coherent quasiparticles residing on the Fermi arcs detected in photoemission experiments. The microscopic origin of the mid-IR band is yet to be understood. A combination of transport and IR data uncovers fingerprints of the Fermi liquid behavior in the response of the nodal metal. The comprehensive nature of the data sets presented in this work allows us to critically re-evaluate common approaches to the interpretation of the optical data. Specifically we re-examine the role of magnetic excitations in generating electronic self energy effects through the analysis of the IR data in high magnetic field.

description: We investigate the effects of an external magnetic field in the gap structure of a color superconductor with three massless quark flavors. Using an effective theory with four-fermion interactions, inspired by one-gluon exchange, we show that the long-range component $\widetilde{B}$ of the external magnetic field that penetrates the color-flavor locked (CFL) phase modifies its gap structure, producing a new phase of lower symmetry. A main outcome of our study is that the $\widetilde{B}$ field tends to strengthen the gaps formed by $\widetilde{Q}$-charged and $\widetilde{Q}$-neutral quarks that coupled among themselves through tree-level vertices. These gaps are enhanced by the field-dependent density of states of the $\widetilde{Q}$-charged quarks on the Fermi surface. Our considerations are relevant for the study of highly magnetized compact stars.

description: Beam self-imaging in nonlinear graded-index multimode optical fibers is of interest for many applications, such as implementing a fast saturable absorber mechanism in fiber lasers via multimode interference. We obtain an exact solution for the nonlinear evolution of first and second order moments of a laser beam carried by a graded-index multimode fiber, predicting that the spatial self-imaging period does not vary with power. Whereas the amplitude of the oscillation of the beam width is power-dependent. We have experimentally studied the longitudinal evolution of beam self-imaging by means of femtosecond laser pulse propagation in both the anomalous and the normal dispersion regime of a standard telecom graded-index multimode optical fiber. Light scattering out of the fiber core via visible fluorescence emission and harmonic wave generation permits us to directly confirm that the self-imaging period is invariant with power. Spatial shift and splitting of the self-imaging process under the action of self-focusing are also emphasized.

description: We discuss the relationship between holographic entropy bounds and gravitating systems. In order to obtain a holographic energy density, we introduce the Bekenstein-Hawking entropy $S_{\rm BH}$ and its corresponding energy $E_{\rm BH}$ using the Friedman equation. We show that the holographic energy bound proposed by Cohen {\it et al} comes from the Bekenstein-Hawking bound for a weakly gravitating system. Also we find that the holographic energy density with the future event horizon deriving an accelerating universe could be given by vacuum fluctuations of the energy density.

European Takeover Law: The Case for a Neutral Approach

description: This paper argues that in revising the Takeover Bid Directive, EU policymakers should adopt a neutral approach toward takeovers, i.e. enact rules that neither hamper nor promote them. The rationale behind this approach is that takeovers can be both value-creating and value-decreasing and there is no way to tell ex ante whether they are of the former or the latter kind. Unfortunately, takeover rules cannot be crafted so as to hinder all the bad takeovers while at the same time promoting the good ones. Further, contestability of control is not cost-free, because it has a negative impact on managers’ and block-holders’ incentives to make firm-specific investments of human capital, which in turn affects firm value. It is thus argued that individual companies should be able to decide how contestable their control should be. After showing that the current EC legal framework for takeovers overall hinders takeover activity in the EU, the paper identifies three rationales for a takeover-neutral intervention of the EC in the area of takeover regulation (pre-emption of “takeover-hostile,” protectionist national regulations, opt-out rules protecting shareholders vis-à-vis managers’ and dominant shareholders’ opportunism in takeover contexts, and menu rules helping individual companies define their degree of control contestability) and provides examples of rules that may respond to such rationales.

description: Ground level ozone remains a serious problem in the United States. Because ozone non-attainment is a summer problem, episodic rather than continuous controls of ozone precursors are possible. We evaluate the costs and effectiveness of an episodic scheme that requires people to buy permits in order to drive on high ozone days. We estimate the demand function for permits based on a survey of 1,300 households in the Washington, DC metropolitan area. Assuming that all vehicle owners comply with the scheme, the permit program would reduce VOCs by 50 tons and NOx by 42 tons per Code Red day at a permit price of $75. Allowing for non-compliance by 15% of respondents reduces the effectiveness of the scheme to 39 tons of VOCs and 33 tons of NOx per day. The cost per ozone season of achieving these reductions is approximately $9 million (2008 USD). This compares favorably with permanent methods of reducing VOCs that cost $645 per ton per year.

description: Novel early stage ideas face uncertainty on the expertise needed to elaborate them, which creates a need to circulate them widely to find a match. Yet as information is not excludable, shared ideas may be stolen, reducing incentives to innovate. Still, in idea-rich environments inventors may share them without contractual protection. Idea density is enhanced by firms ensuring rewards to inventors, while their legal boundaries limit idea leakage. As firms limit idea circulation, the innovative environment involves a symbiotic interaction: firms incubate ideas and allow employees to leave if they cannot find an internal fit; markets allow for wide circulation of ideas until matched and completed; under certain circumstances ideas may be even developed in both firms and markets.

description: Established firms often fail to maintain leadership following disruptive market shifts. We argue that such firms are more prone to internal resistance.

Partial adaptation may lead winners to depart to form new firms with no goodwill, but no internal resistance.

description: We provide a new approach for assessing the cost of marginal ecosystem changes and the effectiveness of green payment schemes. The approach is based on a theoretical and empirical analysis of the bio-economic production interactions between marketed outputs and non-marketed ecosystem services at the micro level. To frame the economic nature of the problem, we employ a generalized joint production model in combination with cost minimization. The generalized joint production framework allows for the consideration of complementary, supplementary and competitive relationships between agricultural production and non-marketed ecosystem services generation and avoids double counting. From this theoretical model we distinguish three theoretical cases depending on the imposed minimum acceptable level of the non-marketed ecosystem services. We employ farm level panel data for the UK to empirically investigate these cases. More specifically, to represent and evaluate the production structure, we estimate first- and second-order elasticities derived from a flexible transformation function. Results show that the majority of farms produce agricultural output and ecosystem services in a complementary relationship. Generation of multiple ecosystem services on the same farm showed either a supplementary or competitive relationship. Changing the composition of the ecosystem services output would have very different implications for individual farms.

description: Modern driver assistance systems as well as autonomous vehicles take their decisions based on local maps of the environment. These maps include, for example, surrounding moving objects perceived by sensors as well as routes and navigation information. Current research in the field of environment mapping is concerned with two major challenges. The first one is the integration of information from different sources e.g. on-board sensors like radar, camera, ultrasound and lidar, offline map data or backend information. The second challenge comprises in finding an abstract representation of this aggregated information with suitable interfaces for different driving functions and traffic situations. To overcome these challenges, an extended environment model is a reasonable choice. In this paper, we show that role-based motion predictions in combination with v2x-extended environment models are able to contribute to increased traffic safety and driving comfort. Thus, we combine the mentioned research areas and show possible improvements, using the example of a threading process at a motorway access road. Furthermore, it is shown that already an average v2x equipment penetration of 80% can lead to a significant improvement of 0.33m/s^2 of the total acceleration and 12m more safety distance compared to non v2x-equipped vehicles during the threading process.

Therefore, it is determined linkages indexes of Rasmussen-Hirschman, boarding fields, pure linkage index (GHS) and regional multipliers of product, income and employment. These applications are complementary to the identification of key sectors of the economy. The 1995 input-output matrix was used. Linkages indexes of Rasmussen-Hirschman and the analysis of the influence field pointed out that coffee production presents multiplying indicators above those of the economy, presenting higher backward and forward linkages. The coffee processing sector presents only backward linkage effects. In the multipliers analysis, it was observed that coffee production sector showed better performance in terms of product and income generation, while the coffee processing industry, in terms of product and of job multipliers

For the integral flow, we discuss the interplay between collective expansion and spectator shadowing for three centrality classes. A complete excitation function of transverse momentum dependence of elliptic flow is presented for the first time in this energy range, revealing a rapid change with incident energy below 0.4 AGeV, followed by an almost perfect scaling at the higher energies. The equation of state of compressed nuclear matter is addressed through comparisons to microscopic transport model calculations.

description: This study aimed at the technical-economical evaluation of implanting some vegetal-oil extraction units in order to insert the family agriculture into bio-diesel production chain. Three project models (arrangements) for vegetal-oil extraction units at different sizes were proposed, using extraction by pressing and mixed extraction (extracting by either pressing or solvent) and different raw materials (castor-oil and soybean). For the size analysis, the oil production scales between 50/60 tons/day were used with real market data concerning investments, inputs prices of the process, raw materials and vegetal oil. For the economic analyses, the software BioSoft was used. The BioSoft is a program for supporting the decision-making process, which was developed through analyzing units of bio-diesel production, and it was adapted to evaluate units of vegetal oil extraction. It was concluded that the unit of chemical extraction producing castor and soybean oils shows more satisfactory results. However, this model presents less social return because the number of the families involved is lower, once, in using soybean, it operates with only 50% of raw material deriving from family agriculture.

description: In this paper, a semi-simple and Maxwell extension of the (anti) de Sitter algebra is constructed. Then, a gauge-invariant model has been presented by gauging the Maxwell semi-simple extension of the (anti) de Sitter algebra. We firstly construct a Stelle-West like model action for five-dimensional space-time in which the effects of spontaneous symmetry breaking have been taken into account. In doing so, we get an extended version of Einstein's field equations. Next, we decompose the five-dimensional extended Lie algebra and establish a MacDowell-Mansouri like action that contains the Einstein-Hilbert term, the cosmological term as well as new terms coming from Maxwell extension in four-dimensional space-time where the torsion-free condition is assumed. Finally, we have shown that both models are equivalent for an appropriately chosen gauge condition.

description: Coarse-grained modeling of dynamics on vicinal surfaces concentrates on the diffusion of adatoms on terraces with boundary conditions at sharp steps, as first studied by Burton, Cabrera and Frank (BCF). Recent electromigration experiments on vicinal Si surfaces suggest the need for more general boundary conditions in a BCF approach. We study a discrete 1D hopping model that takes into account asymmetry in the hopping rates in the region around a step and the finite probability of incorporation into the solid at the step site. By expanding the continuous concentration field in a Taylor series evaluated at discrete sites near the step, we relate the kinetic coefficients and permeability rate in general sharp step models to the physically suggestive parameters of the hopping models. In particular we find that both the kinetic coefficients and permeability rate can be negative when diffusion is faster near the step than on terraces. These ideas are used to provide an understanding of recent electromigration experiment on Si(001) surfaces where step bunching is induced by an electric field directed at various angles to the steps.

description: Starting in 1969, small groups of West Papuans have occasionally crossed the Torres Strait to Australia and sought its protection. In public discourse, these arrivals have figured as part of a narrative about Australia’s relationship with Indonesia. By contrast, in the public discourse about border control, which focuses on attempted travel across the Indian Ocean and distinct ‘waves’, they have been treated as a footnote, at most. In this article, we closely examine the Australian government’s response to West Papuan ‘boat people’ over time to demonstrate that, unlike in public discourse, border control considerations have loomed large in the government’s response. We argue that, in order to understand Australia’s approach to border control, we should see West Papuan asylum seekers in the context of border control policy and not only as a problem in Australia’s relationship with Indonesia.

description: Gravitational waves from the coalescence of binary black holes carry linear momentum, causing center of mass recoil. This ``radiation rocket'' has important implications for systems with escape speeds of order the recoil velocity. We describe new recoil calculations using high precision black hole perturbation theory to estimate the magnitude of the recoil for the slow ``inspiral'' coalescence phase; coupled with a cruder calculation for the final ``plunge'', we estimate the total recoil imparted to a merged black hole. We find that velocities of many tens to a few hundred km/sec can be achieved fairly easily. The recoil probably never exceeds about 500 km/sec.

description: At low redshift, there are fundamental correlations between the mass of supermassive black holes (MBH) and the mass (Mbulge) and luminosity of the host galaxy bulge. We investigate the same relation at z>=1. Using virial mass estimates for 11 quasars at z >~2 to measure their black hole mass, we find that black holes at high z fall nearly on the same MBH versus R-band magnitude (MR) relation (to ~0.3 mag) as low-redshift active and inactive galaxies, without making any correction for luminosity evolution. Using a set of conservative assumptions about the host galaxy stellar population, we show that at z>~2 (10 Gyrs ago) the ratio of MBH/Mbulge was 3--6 times larger than today. Barring unknown systematic errors on the measurement of MBH, we also rule out scenarios in which moderately luminous quasar hosts at z>~2 were fully formed bulges that passively fade to the present epoch. On the other hand, 5 quasar hosts at z~1 are consistent with current day MBH-MR relationship after taking into account evolution, appropriate for that of E/S0 galaxies. Therefore, z~1 host galaxies appear to fit the hypothesis they are fully formed early-type galaxies. We also find that most quasar hosts with absolute magnitudes brighter than MR = -23 cannot fade below L* galaxies today, regardless of their stellar population makeup, because their black hole masses are too high and they must arrive at the local MBH-MR relationship by z=0.

description: This study examines aggregate county income growth across the 48 contiguous states from 1990 to 2005. To control for endogeneity we estimate a two-stage spatial error model and infer parameter significance by implementing a number of spatial bootstrap algorithms. We find that outdoor recreation and natural amenities favor positive growth in rural counties, densely populated rural areas enjoy stronger growth, and property taxes correlate negatively with rural growth. We also compare estimates from the aggregate county income growth model with per capita income growth and find that these two growth processes can be quite different.

description: Double-pass polarimetry measures the polarization properties of a sample over a range of polar angles and all azimuths. Here, we present a tolerance analysis of all the optical elements in both the calibration and measurement procedures to predict the sensitivities of the double-pass polarimeter. The calibration procedure is described by a Mueller matrix based on the eigenvalue calibration method (ECM). Our numerical results from the calibration and measurement in the Mueller matrix description with tolerances limited by systematic and stochastic noise from specifications of commercially available hardware components are in good agreement with previous experimental observations. Furthermore, by using the orientation Zernike polynomials (OZP) which are an extension of the Jones matrix formalism, similar to the Zernike polynomials wavefront expansion, the pupil distribution of the polarization properties of non-depolarizing samples under test are expanded. Using polar angles ranging up to 25$^{\circ}$, we predict a sensitivity of 0.5% for diattenuation and 0.3$^{\circ}$ for retardance using the root mean square (RMS) of the corresponding OZP coefficients as a measure of the error. This numerical tool provides an approach for further improving the sensitivities of polarimeters via error budgeting and replacing sensitive components with those having better precision.

description: Using the 770 ksec XMM-Newton survey of the Lockman Hole field in combination with extensive optical identifications of the AGN population, we derive an average rest-frame spectrum of AGN types-1 and 2. The most prominent feature in the averaged spectrum is a strong fluorescent Fe line. In both type-1 and type-2 AGN, a clear relativistic line profile is rev ealed. A laor line profile with an inner disk radius smaller than the last stabl e orbit of a Schwarzschild black hole is most consistent with the data, indicati ng that the average supermassive black hole has significant spin. Equivalent wid ths of the broad relativistic lines range between 400--600 eV. We used the disk reflection model to compare the observed strength of the line with the amplitude of the reflection component, concluding that to consistently describe the observations the average iron abundance should be about three times the solar value.

description: Within developing embryos, tissues flow and reorganize dramatically on timescales as short as minutes. This includes epithelial tissues, which often narrow and elongate in convergent extension movements due to anisotropies in external forces or in internal cell-generated forces. However, the mechanisms that allow or prevent tissue reorganization, especially in the presence of strongly anisotropic forces, remain unclear. We study this question in the converging and extending Drosophila germband epithelium, which displays planar polarized myosin II and experiences anisotropic forces from neighboring tissues, and we show that in contrast to isotropic tissues, cell shape alone is not sufficient to predict the onset of rapid cell rearrangement. From theoretical considerations and vertex model simulations, we predict that in anisotropic tissues two experimentally accessible metrics of cell patterns, the cell shape index and a cell alignment index, are required to determine whether an anisotropic tissue is in a solid-like or fluid-like state. We show that changes in cell shape and alignment over time in the Drosophila germband predict the onset of rapid cell rearrangement in both wild-type and snail twist mutant embryos, where our theoretical prediction is further improved when we also account for cell packing disorder. These findings suggest that convergent extension is associated with a transition to more fluid-like tissue behavior, which may help accommodate tissue shape changes during rapid developmental events.
