Social movements as learning communities : Chilean exiles and knowledge production in and beyond the solidarity movement
Creators: name: Palacios, Carolina
Publisher: name: University of British Columbia
Year: 2011

description: The atrocities committed by the military in Chile after the armed forces seized power in 1973 horrified Chileans and people around the world who had been following events in Chile for years prior to the coup. Together with the resistance in Chile, the transnational solidarity movement integrated by Chilean exiles and non-Chileans across the globe played a major role in ending the dictatorship. Since in-depth empirical studies of social movement learning are sparse this study addresses this gap as well as the ones in the existent research on the Chilean solidarity movement in Canada and elsewhere, the political activities of Chilean exiles in Canada and the Chilean solidarity movement specifically from a learning perspective. The purposes of this research, therefore, were to document and understand collective learning processes among solidarity movement participants and to contribute to the empirical and theoretical social movement learning scholarship. This study employed qualitative historical research methods, including oral history interviews and reviewing formal and informal archives. The conceptual tools used to understand solidarity movement learning and knowledge production drew broadly on new social movement thought and in particular on Freire, Gramsci and Habermas, which enabled an analysis of wider social forces, the specific pedagogies of the solidarity movement and the connections between the two. The findings speak to the value of a varied repertoire of action which merges the political with the cultural and which blends the intellectual with the emotional and the sensory. They also point to the power of artistic forms of expression for articulating and communicating social movement messages and for expressing identities. In addition, the findings show the local, experiential knowledge generated in social movements is vital to achieving movement aims, to critical learning and transformation, and to constructing individual and collective social movement identities. The study concludes that understanding social movements as learning communities is essential because it foregrounds the value and legitimacy of movement knowledge and the centrality of learning and knowledge production to movement aims and to the significance of movements for movement members, their allies and the public.

description: The primary aim of copyright law is to promote the creation and dissemination of knowledge by protecting the economic rights of authors. Economic rights, though valuable; do not encompass the free speech rights that can be threatened by the tension between copyright and the First Amendment. Conflicts between copyright law and the First Amendment are sometimes characterized as pitting the economic rights of authors against the free speech rights of those who wish to use their copyrighted works. The so-called fair use doctrine and the idea/expression dichotomy—two exceptions to copyright law's categorical prohibition on copying—are often touted as sufficient to accommodate the First Amendment problems raised by copyright law. However, in copyright cases in which an author's message is distorted in ways she disavows, these two exceptions are inadequate to protect original authors' free speech rights, which may be in jeopardy.
CHD6 and the oxidative stress-induced DNA damage response

Subjects: subject: Biology--Molecular

description: Oxidative stress-induced DNA damage is a threat to the health and survival of a cell. Oxidative DNA damage responses involve nucleosome displacement, exchange or removal by ATP-dependent chromatin remodeling enzymes to promote DNA repair and transcriptional events. The CHD6 (Chromodomain, Helicase, DNA-binding 6) chromatin remodeling enzyme has been identified as an interactor of NFE2-related factor 2 (NRF2), a key transcription factor in the oxidative stress response. Several human ataxias have linkage map regions that encompass the CHD6 gene locus (20q11.1-12), while catalytically-inactive CHD6 mutant mice exhibit motor coordination defects most consistent with a cerebellar neuron disorder. Here, I describe a role for CHD6 in the response to oxidative stress-induced DNA damage. CHD6 relocates rapidly to DNA damage caused by microirradiation or KillerRed-induced oxidative stress, but not to enzyme-induced DNA double strand breaks. CHD6 interacts with poly ADP-ribose (PAR), and retention at laser microirradiation-induced DNA damage sites is PAR polymerase-dependent and prolonged by PAR Glycohydrolase depletion. I have narrowed down the PAR-interaction region of CHD6 to the extreme N-terminus and, using laser microirradiation, I have demonstrated the importance of the double chromodomain and a putative DNA-binding domain for normal recruitment to DNA-damage tracks. CHD6 protein levels are stabilized following H2O2 exposure via suppressed proteolytic degradation. Ablation of CHD6 in A549 cells using CRISPR-Cas9 led to elevated reactive oxygen species levels, created an impaired antioxidant response and a reduced ability to survive or proliferate following chronic H2O2 exposure. CHD6-deleted cells displayed elevated γH2AX and 53BP1 foci, increased ATM auto-phosphorylation and a hypersensitive G2/M checkpoint after exposure to ionizing radiation or H2O2. In conclusion, my data identify CHD6 as a novel responder to oxidative stress-induced DNA damage.

description: The structure of ${}^{17}$C is used to define a nuclear interaction that, when used in a multichannel algebraic scattering theory for the $n+{}^{16}$C system, gives a credible definition of the (compound) excitation spectra. When couplings to the low-lying collective excitations of the ${}^{16}$C-core are taken into account, both sub-threshold and resonant states about the $n+{}^{16}$C threshold are found. Adding Coulomb potentials to that nuclear interaction, the method is used for the mirror system of $p+{}^{16}$Ne to specify the low-excitation spectrum of the particle unstable $^{17}$Na. We compare the results with those of a microscopic cluster model. A spectrum of low excitation resonant states in ${}^{17}$Na is found with some differences to that given by the microscopic-cluster model. The calculated resonance half-widths (for proton emission) range from $\sim 2$ to $\sim 672$ keV.

HIV-1 infection and the central nervous system: investigating markers of neural activation and measures of HIV-1 reservoir
Creators: name: Alagaratnam, Jasmini
Publisher: name: Imperial College London
Year: 2021

description: Despite successful antiretroviral therapy (ART), mild cognitive impairments remain prevalent amongst people-living-with-HIV (PLWH). However, the underlying mechanisms driving this remain unclear. The persistence of an inaccessible HIV reservoir and low-level viral replication may be associated with immune activation and neuroinflammation, which can lead to neuronal injury and cognitive impairment. Furthermore, HIV-cure and ART-interruption strategies which disturb the HIV reservoir could result in detrimental central nervous system (CNS) sequelae. This thesis examines the following hypotheses: 1. Lower biomarker concentrations of HIV reservoir size are associated with lower biomarker concentrations of neural activation 2. Higher biomarker concentrations of HIV viral transcription are associated with higher biomarker concentrations of neural activation In cross-sectional analyses of virologically suppressed PLWH, associations were assessed between cerebrospinal fluid and plasma neurofilament light chain protein (NfL), and between surrogate measures of HIV reservoir size and neuroinflammation, measured in vivo using translocator protein (TSPO) binding on positron emission tomography neuroimaging (a marker of microglial activation). In longitudinal analyses, I assessed the impact of “shock-and-kill” using vorinostat + HIV-specific vaccination (a HIV-remission strategy) and ART interruption on measures of HIV reservoir size, HIV replication and plasma NfL, in individuals who initiated ART during primary HIV infection. My results demonstrated that cerebrospinal fluid and plasma NFL correlated moderately but I was unable to confirm an association between HIV reservoir size and neuroinflammation, as measured by TSPO binding. Using plasma NfL, the absence of associations between HIV reservoir size and replication with neuronal injury following this “shock-and-kill” strategy or ART interruption supports the presumption of CNS safety of these approaches and will inform the design of future HIV-cure studies. With the imminent introduction of novel therapeutics to control and cure HIV, continued CNS safety monitoring remains essential, and the implementation of CNS assessment using the aforementioned biomarkers was demonstrated to be feasible.

description: The potential for working memory training to enhance cognitive and intellectual abilities is alluring across scientific disciplines and the general public. However, the field has been fraught with inconsistency and controversy. Heterogeneous methodological implementations have led to a divided and contrasting body of literature, which has collectively limited scientific transparency and advancement in the field. However, neuroimaging has the potential to clarify what, if any, benefit working memory training has on the adult human brain. A recent series of studies used functional neuroimaging to investigate neural activations associated with working memory training. This dissertation uses structural imaging to address another theoretical area: the neuroanatomical correlates of working memory training. Forty-eight healthy community dwelling adults, aged 18 - 40 years, completed a series of cognitive tasks and underwent magnetic resonance imaging (MRI) before and after completing a 6-week trial of working memory training (experimental condition) or processing speed training (active control condition). Group by time repeated measures Analyses of Variance (rm-ANOVAs) were conducted on MRI data to identify changes in surface area, thickness, and volume in theoretically relevant gray matter regions of interest, as well as overall gray and white matter volumes, associated with working memory training. Similar analyses were conducted to investigate changes in cognitive task performance in this sample. Null results were present across all neuroanatomical metrics after correction for multiple comparisons, and findings from cognitive tasks were consistent with the subset of literature suggesting that working memory training does not meaningfully benefit cognitive performance. Albeit limited by low statistical power and the confines of available technology, findings of this study, in consort with recently published investigations, strongly support the idea that working memory training is not an effective method for enhancing cognitive performance or inducing neoplastic changes in brain structure. We suggest that future studies continue attempts to resolve heterogeneity and polarization in this field, or alternatively, concentrate resources on identifying and refining mechanisms of change in populations who may benefit from rehabilitative forms of cognitive training.
Distinguishing mesoscopic quantum superpositions from statistical mixtures in periodically shaken double wells

Year: 2011
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: For Bose-Einstein condensates in double wells, N-particle Rabi-like oscillations often seem to be damped. Far from being a decoherence effect, the apparent damping can indicate the emergence of quantum superpositions in the many-particle quantum dynamics. However, in an experiment it would be difficult to distinguish the apparent damping from decoherence effects. The present paper suggests using controlled periodic shaking to quasi-instantaneously switch the sign of an effective Hamiltonian, thus implementing an `echo' technique which distinguishes quantum superpositions from statistical mixtures. The scheme for the effective time-reversal is tested by numerically solving the time-dependent N-particle Schrodinger equation.

Optimal Target Criteria for Stabilization Policy

Publisher: name: Columbia University
Year: 2010
Subjects: Economics

description: This paper considers a general class of nonlinear rational-expectations models in which policymakers seek to maximize an objective function that may be household expected utility. We show how to derive a target criterion that is: (i) consistent with the model's structural equations, (ii) strong enough to imply a unique equilibrium, and (iii) optimal, in the sense that a commitment to adjust the policy instrument at all dates so as to satisfy the target criterion maximizes the objective function. The proposed optimal target criterion is a linear equation that must be satisfied by the projected paths of certain economically relevant "target variables." It takes the same form at all times and generally involves only a small number of target variables, regardless of the size and complexity of the model. While the projected path of the economy requires information about the current state, the target criterion itself can be stated without reference to a complete description of the state of the world. We illustrate the application of the method to a nonlinear DSGE model with staggered price-setting, in which the objective of policy is to maximize household expected utility.
Son Preference, Sex Selection and Economic Development

Year: 2009
Subjects: Economics

description: Motivated by high and rising sex ratios in countries such as India and China, we formulate a theoretical framework for analyzing the impact of economic development on parental sex choice when sons are culturally prized and children provide old age support. Two key assumptions drive our model. First, the cultural valuation of children varies not only with gender but also with marital status. In particular, while a married son is preferred to a married daughter, the latter is preferred to an unmarried son. Second, we assume that faced with a shortage of brides, poor parents will have a harder time marrying their sons than rich parents. Our model predicts male sex ratios at low levels of development, where the surplus sons are chosen by the poorest who forego grandchildren for old age support. With development, incomes and the bride price rise, allowing the poorest reproductive children. Consequently, sex ratios fall, and the relationship between parental income and offspring maleness turns positive. We also present corroborative evidence from South Korea, a now developed country which shares with India and China a strong patriarchal culture and a recent past of poverty.

description: Since the first major influx in 1984, Thailand has witnessed a steady stream of refugees from Myanmar entering its borders. Many of these refugees live in camps along the Thai-Myanmar border. Despite having large numbers of refugees, Thailand does not have an established legal framework to deal with them. In recent years, the Thai government has proposed the establishment of a Special Economic Zone (SEZ) and a Special Administrative Zone (SAZ) in Tak Province; a province that houses the largest number of Myanmar refugees, living in refugee camps, in Thailand. This case encourages readers to analyse the Thai government’s proposals through the lens of a Cost Benefit Analysis.

Doctors, Patients, and the Racial Mortality Gap

Subjects: Economics

description: Disparities in health outcomes between white and minority Americans are a significant and well documented challenge in improving equity in healthcare. Two frequently cited explanations are discrimination in treatment - doctors treating minority patients differently, and unequal access to care - patients being trapped in facilities of inferior quality. I use a new dataset from the Department of Veterans Affairs and employ a novel estimation strategy to investigate the sources of the racial gap in mortality for chronic heart disease, the most expensive chronic condition in the elderly. I find that racial differences in mortality persist even when the quality of clinics and doctors is controlled for. Investigating the doctor-patient interaction, I show that doctor quality significantly influences patient outcomes. While minority patients visit slightly less competent doctors, this does not explain the large gap in survival. Individual doctors are found to treat their patients similarly regardless of race. On the patient side, I demonstrate that variation in compliance triggers a racial mortality gap. Differences in patient response to treatment significantly alter survival probabilities. Considerable reductions in medical costs could be achieved by convincing patients of the importance of strictly following the therapy regimen. I estimate that targeting compliance patterns could reduce the black-white mortality gap by at least two-thirds.

description: This project details an architectural investigation o f two buildings (Buildings 9001 and 9007) located on the Fort Dix Military Installation in Burlington County, New Jersey. Due to the need to close the wells under these two buildings in accordance with current New Jersey Department of Environmental Protection regulations and the lack of any foreseeable need for these presently unused structures, the U S. Army has proposed to demolish these buildings in order to access the wells. In accordance with regulations concerning the protection of cultural resources on the installation, the U.S. Army has required the contractors performing the capping of the wells to ensure that Buildings 9001 and 9007 are documented prior to demolition. Richard Grubb & Associates, Inc. was sub-contracted to examine the two buildings and make recommendations for a determination of eligibility for listing on the National Register of Historic Places and for Pinelands Designation.
Neither of the buildings is eligible for listing on the National Register of Historic Places, nor are they eligible for Pinelands Designation. The buildings did not play a significant role in the military or civilian history of the United States, nor did they play a significant role in the local history of Fort Dix. Neither building contains architectural or engineering significance As neither building is eligible for listing on the National Register of Historic Places or for Pinclands Designation, the project is recommended for clearance and demolition of the buildings may proceed.

description: We find necessary and sufficient conditions for gauge invariance of the action of Double Field Theory (DFT) as well as closure of the algebra of gauge symmetries. The so-called weak and strong constraints are sufficient to satisfy them, but not necessary. We then analyze compactifications of DFT on twisted double tori satisfying the consistency conditions. The effective theory is a Gauged DFT where the gaugings come from the duality twists. The action, bracket, global symmetries, gauge symmetries and their closure are computed by twisting their analogs in the higher dimensional DFT. The non-Abelian heterotic string and lower dimensional gauged supergravities are particular examples of Gauged DFT.

description: We analyze the dynamics of a classical particle in a spatially periodic potential under the influence of a periodic in time uniform force. It was shown in [S.Flach, O.Yevtushenko, Y. Zolotaryuk, Phys. Rev. Lett. 84, 2358 (2000)] that despite zero average force, directed transport is possible in the system. Asymptotic description of this phenomenon for the case of slow driving was developed in [X. Leoncini, A. Neishtadt, A. Vasiliev, Phys. Rev. E 79, 026213 (2009)]. Here we consider the case of fast driving using canonical perturbation theory. An asymptotic formula is derived for the average drift velocity as a function of the system parameters and the driving law. We show that directed transport arises in an effective Hamiltonian that does not possess chaotic dynamics, thereby clarifying the relation between chaos and transport in the system. Sufficient conditions for transport are derived.

As a consequence, if $2^ μ\leq λ$, then the product of any family of weakly initially $λ$-compact spaces is weakly initially $μ$-compact.

Correlated Disturbances and U.S. Business Cycles

Year: 2010
Subjects: Economics

description: The dynamic stochastic general equilibrium (DSGE) models that are used to study business cycles typically assume that exogenous disturbances are independent autoregressions of order one. This paper relaxes this tight and arbitrary restriction, by allowing for disturbances that have a rich contemporaneous and dynamic correlation structure. Our first contribution is a new Bayesian econometric method that uses conjugate conditionals to make the estimation of DSGE models with correlated disturbances feasible and quick. Our second contribution is a re-examination of U.S. business cycles. We find that allowing for correlated disturbances resolves some conflicts between estimates from DSGE models and those from vector autoregressions, and that a key missing ingredient in the models is countercyclical fiscal policy. According to our estimates, government spending and technology disturbances play a larger role in the business cycle than previously ascribed, while changes in markups are less important.

description: The main purpose of this study is to investigate the determinants of innovative success of small to medium enterprises in Ethiopia. A qualitative research approach was employed in the investigation. Instruments used to collect data were semi-structured interviews. Accordingly, through face-to-face interviews with 49 owners/managers of small to medium enterprises data were collected. With this study, many determinant factors of product innovative success were identified. However, the three strategic types; namely entrepreneurial orientation, market information processing and network ties were identified as the highly important while experience of workers and education levels of owners/managers of small firms were also mentioned as other factors. Also, the importance of market information utilization and network ties with other enterprises have been great but contributions of the so-called technology-issuing information channels were not significantly used by many enterprises. But, until now, the market information was not as much formally acquired and utilized by many small firms to produce a planning, competitor analysis, internal analysis and for product innovation. Therefore, recommend as all the information together should be used to produce a new product that help for product innovation success.

Voltages induced in the loops during discharge of the solenoid will be sampled online during the entire discharge and integrated offline to provide a measurement of the initial magnetic flux density in steel at the maximum field to an accuracy of a few percent. Although the discharge of the solenoid is rather slow (190 s time constant), the influence of eddy currents induced in the yoke elements should be estimated. The calculation of eddy currents is performed with Vector Fields' program ELEKTRA. The results of the calculations are reported.

description: This paper analyses the mobilization actions among Latino populations in the United States, especially Mexican and Central American immigrants, triggered by the passage of H.R. 4437 by the U.S. House of Representatives on December 16, 2005. I expose the actors, their rationale, and mechanisms of mobilization that have raised to a historical proportion the current U.S. immigration debate. From a theoretical standpoint, I develop an analytical framework that addresses these events within the field of political transnationalism. The empirical analysis includes three levels: from a macro-meso perspective, this work suggests that mobilization actions can be explained mainly through the involvement of the Catholic Church and immigrant-supportive organizations in 32 cities across the nation. From a micro perspective, this research suggests that faith, work and family are the triggering factors for Latinos and Latino immigrants to participate in political mobilizations of this type.

description: The Simple Spectral Access (SSA) Protocol (SSAP) defines a uniform interface to remotely discover and access one dimensional spectra. SSA is a member of an integrated family of data access interfaces altogether comprising the Data Access Layer (DAL) of the IVOA. SSA is based on a more general data model capable of describing most tabular spectrophotometric data, including time series and spectral energy distributions (SEDs) as well as 1-D spectra; however the scope of the SSA interface as specified in this document is limited to simple 1-D spectra, including simple aggregations of 1-D spectra. The form of the SSA interface is simple: clients first query the global resource registry to find services of interest and then issue a data discovery query to selected services to determine what relevant data is available from each service; the candidate datasets available are described uniformly in a VOTable format document which is returned in response to the query. Finally, the client may retrieve selected datasets for analysis. Spectrum datasets returned by an SSA spectrum service may be either precomputed, archival datasets, or they may be virtual data which is computed on the fly to respond to a client request. Spectrum datasets may conform to a standard data model defined by SSA, or may be native spectra with custom project-defined content. Spectra may be returned in any of a number of standard data formats. Spectral data is generally stored externally to the VO in a format specific to each spectral data collection; currently there is no standard way to represent astronomical spectra, and virtually every project does it differently. Hence spectra may be actively mediated to the standard SSA-defined data model at access time by the service, so that client analysis programs do not have to be familiar with the idiosyncratic details of each data collection to be accessed.
Advanced transceiver algorithm design for cognitive radio physical layer

Publisher: name: University of British Columbia

description: With the ever increasing demand for wireless applications, current wireless systems are challenged to meet the higher data rate and higher reliability requirements. Although the current and future technological developments allow making these requirements reachable, some other resources remain limited. The radio spectrum is one such natural resource. Previous studies have shown that the radio spectrum is not efficiently utilized. Therefore, recent studies are focused on fully utilizing this unexpandable radio spectrum. Cognitive radio (CR) has emerged as a possible solution to improve the spectrum utilization by opportunistically exploiting the licenced users transmit spectrum in dynamically changing environments. On the other hand, the development of CR technology raises new challenges of proper design of transmission and receive schemes for CR to facilitate high data rate access and better performance along with high spectral efficiency. To achieve these objectives, in this thesis, advanced transceiver algorithms for CR physical layer are designed to improve the throughput and the error rate performance in hostile wireless channels. We first designed a linear precoder for orthogonal space-time block coded, orthogonal frequency division multiplexing (OFDM)-based multiple-input multiple-output antenna CR when operating in correlated Rayleigh fading channels. The linear precoder is designed by minimizing an upper bound on the average pairwise error probability, constrained to a set of per subcarrier power constraints at CR transmitter and a set of primary users interference power thresholds. An efficient algorithm is proposed to obtain the optimal precoder matrices. We then proposed a power allocation policy to achieve a lower-bound on the ergodic sum capacity of single-input single-output opportunistic spectrum sharing multiple access channel with imperfect channel estimates. An efficient algorithm is proposed to obtain the optimal power allocation for each CR transmitter. Finally, we proposed a blind parameter estimation algorithm for OFDM signal affected by a time-dispersive channel, carrier phase, timing offset, carrier frequency offset and additive Gaussian noise. The cyclostationarity properties of received OFDM signal in time-dispersive channel is exploited to estimate the OFDM parameters. These parameters includes OFDM symbol period, useful symbol period, cyclic prefix factor, number of subcarriers and carrier frequency offset.

description: We have it on the highest authority—Justice Souter writing for a unanimous Court in Hurley v. Irish-American Gay, Lesbian & Bisexual Group of Boston—that the paintings of Jackson Pollock are "unquestionably shielded" by the First Amendment. Of course we probably knew that from the development of obscenity law, driven as it was by a need to ensure that the proscription of obscenity not lead to the suppression of depictions that are merely erotic. Beyond authority, though, exactly why are Pollock's paintings covered by the First Amendment? Consider that core First Amendment doctrine places under close scrutiny statutes that regulate speech based on its content, and, under even closer scrutiny, statutes that regulate speech based on the viewpoint it expresses. Yet, what exactly—or even roughly—is the content of Pollock's Blue Poles, No. 11, or the viewpoint it expresses? This Essay explores the question of the First Amendment's coverage of nonrepresentational art, which proves quite difficult to answer satisfactorily—that is, in a doctrinal form that preserves other seemingly "unquestionable" results. Every approach one might take to explaining why the First Amendment covers art—that art is communicative, that it contributes to the creation of a culture of self-directed individuals and others I address—generates odd anomalies. The exploration does not question the conventional conclusion that the First Amendment covers artwork, but rather worries some of the often-unstated assumptions that underlie that conclusion. We will see, for example, that some things one might want to say about the question of whether the First Amendment covers nonrepresentational art lead to the suggestion, implicit in Archibald MacLeish's observation about poetry, that James Joyce's Ulysses might not be covered, surely a peculiar result. I do not mean to question Hurley's assertion about Jackson Pollock's paintings. Rather, I believe that by asking how that conclusion might be justified, we will come across some unexpected facets of the First Amendment, with some implications for other doctrinal areas abutting the First Amendment.

description: An optimized thin film of Iridium oxide (IrOx) nanoparticles with the presence of Nafion was used to encapsulate the redox enzyme, glucose oxidase (GOx). The resulting films showed an excellent response towards the detection of glucose in both an oxygenated and deoxygenated environment. It was shown that IrOx nanoparticles are mediating the direct transfer of electrons from GOx, and functioning as 4th generation glucose sensors. These sensors (0.2 to 0.008 cm2 ) demonstrated excellent stability and precision when they were tested for glucose strictly under deoxygenated environments; with a linear response up to 40 mM glucose and a sensitivity of 0.5 ?A/cm2/mM (in< 0.3 ?M of dissolved 0 2). In parallel work, an immobilized enzyme kinetic model was derived and the implication of the IrOx/GOx film properties on the apparent Km was presented. This model was also applied to experimental data to assess the interpretation of the parameter.

description: The main objective of this study was to investigate the challenges and opportunities of developing students’ communicative competence. To this end, a total of three schools from three different zones such as Sheka, Bench-Maji and Kafa were selected as a study area. To gather the valuable information from the subjects, two instruments, a test for students and questionnaires for both teachers and students were used. To select the sample subjects, purposive sampling and systematic sampling techniques were used for teachers and students, respectively. The result of the study has shown that the students’ communicative competence that was inferred from their performance was an “average” or it was in “good” scale. Furthermore, the test result showed that the students mean score value of their communicative competence is 53.15 with the standard deviation of 9.8 from the result, and the students’ linguistic competence is the least and below average value while the students’ discourse competence and strategic competence were medium. The students’ sociolinguistic competence was higher than average. However, the students and teachers’ responses showed that lack of practice in all macro language skills, students’ shyness and being passive, lack of exposure to English speakers, lack of technology assisted language learning, first language dominance and lack of interest were the main challenges to the development of students’ communicative competence. The finding also indicated that students have very limited number of opportunities such as only those related to teachers and textbooks. Finally, based on the results obtained, EFL teachers should have clear understanding about goals of language teaching and CLT principles’ implementation especially in teaching grammar inductively and in using language for meaningful communication and the ministry of education should provide necessaryperiodic trainings for EFL teachers on CLT principle implementations to improve the students’ communicative competence.

description: FeTexSe1-x (x=0, 0.25, 0.50, 0.75 and 1) system has been studied using density functional theory. Our results show that for FeSe, LDA seems better approximation in terms of magnitude of magnetic energy whereas GGA overestimates it largely. On the other hand for FeTe, GGA is better approximation that gives experimentally observed magnetic state. It has been shown that the height of chalcogen atoms above Fe layers has significant effect on band structure, electronic density of states (DOS) at Fermi level N(EF) and Fermi surfaces. For FeSe the value of N(EF) is small so as to satisfy Stoner criteria for ferromagnetism, (I\timesN(EF)\geq1) whereas for FeTe, since the value of N(EF) is large, the same is close to be satisfied. Force minimization done for FeTexSe1-x using supercell approach shows that in disordered system Se and Te do not share same site and have two distinct z coordinates. This has small effect on magnetic energy but no significant difference in band structure and DOS near EF when calculated using either relaxed or average value of z for chalcogen atoms. Thus substitution of Se at Te site decreases average value of chalcogen height above Fe layers which in turn affect the magnetism and Fermiology in the system. By using coherent-potential approximation for disordered system we found that height of chalcogen atoms above Fe layer rather than chalcogen species or disorder in the anion planes, affect magnetism and shape of Fermi surfaces (FS), thus significantly altering nesting conditions, which govern antiferromagnetic spin fluctuations in the system.

How important is money in the conduct of monetary policy?

description: I consider some of the leading arguments for assigning an important role to tracking the growth of monetary aggregates when making decisions about monetary policy. First, I consider whether ignoring money means returning to the conceptual framework that allowed the high inflation of the 1970s. Second, I consider whether models of inflation determination with no role for money are incomplete, or inconsistent with elementary economic principles. Third, I consider the implications for monetary policy strategy of the empirical evidence for a long-run relationship between money growth and inflation. And fourth, I consider reasons why a monetary policy strategy based solely on short-run inflation forecasts derived from a Phillips curve may not be a reliable way of controlling inflation. I argue that none of these considerations provides a compelling reason to assign a prominent role to monetary aggregates in the conduct of monetary policy.
