Concentrated Disadvantage and Intimate Partner Violence

Year: 2009

description: Research documents numerous individual-level risk factors for adolescent dating violence victimization, as well as an association between area concentrated disadvantage (i.e., areas characterized by high poverty, unemployment, and residential turnover) and partner violence among adults. However, little is known about contextual contributors to adolescent dating violence (DV). Although concentrated disadvantage has been linked to the most severe form of intimate partner violence - partner homicide (IPH) - most such studies have been conducted in urban areas, and have examined only female-victim IPH. In this dissertation, I approach partner violence from an ecological perspective and apply social science theories to predict relationships between contextual disadvantage and partner violence outcomes. In my first paper, I assess the relationship between school disadvantage and adolescent dating violence victimization using data from the National Longitudinal Study of Adolescent Health (n=10,620). In multilevel random effects models controlling for individual and school sociodemographic characteristics, school disadvantage is found to moderate the association between family disadvantage and girls' victimization. However, school disadvantage was unrelated to boys' victimization. In the second paper I explore the ecological relationship between disadvantage and intimate partner homicide rates in North Carolina counties (n=100) using data from the North Carolina Violent Death Reporting System, the 2000 Census, and the North Carolina Council for Women's annual survey of NC domestic violence programs. Using Poisson regression models with population offset terms and controlling for percent of the population age 20-40 years, female-to-male sex ratio, and sex ratio squared, I found county disadvantage was positively related to male-victim IPH but not significantly associated with female-victim IPH; neither relationship varied by county rurality. Further, domestic violence service availability and funding variables were not supported as mediators between county disadvantage and male-victim IPH. Results suggest that contextual disadvantage may have direct or moderating effects on partner violence outcomes, depending on the gender of the victim, age of study participants, severity of outcome studied, and level of data utilized. Future studies should examine the relationship between contextual disadvantage and other partner violence outcomes (e.g., severe victimization and various levels of perpetration) as well as mechanisms by which contextual disadvantage affects such outcomes.

description: We present parallel algorithms for union, intersection and
difference on ordered sets using random balanced binary
trees (treaps [26]). For two sets of size n and m (m ≤ n) the
algorithms run in expected O(mlg(n=m)) work and O(lg n)
depth (parallel time) on an EREW PRAM with scan operations
(implying O(lg2 n) depth on a plain EREW PRAM).
As with the sequential algorithms on treaps for insertion
and deletion, the main advantage of our algorithms are their
simplicity. In fact, our algorithms for set operations seem
simpler than previous sequential algorithms with the same
work bounds, and might therefore also be useful in a sequential
context. To analyze the effectiveness of the algorithms
we implemented both sequential and parallel versions of the
algorithms and ran several experiments on them. Our parallel
implementation uses the Cilk [5] shared memory runtime
system on a 16 processor SGI Power Challenge and a
6 processor Sun Ultra Enterprise 3000. It shows reasonable
speedup: 6.3 to 6.8 speedup on 8 processors of the SGI, and
4.1 to 4.4 speedup on 5 processors of the Sun.

description: Of concern is the study of fractional order Sobolev--type metrics on the group of $H^{\infty}$-diffeomorphism of $\mathbb{R}^{d}$ and on its Sobolev completions $\mathcal{D}^{q}(\mathbb{R}^{d})$. It is shown that the $H^{s}$-Sobolev metric induces a strong and smooth Riemannian metric on the Banach manifolds $\mathcal{D}^{s}(\mathbb{R}^{d})$ for $s >1 + \frac{d}{2}$. As a consequence a global well-posedness result of the corresponding geodesic equations, both on the Banach manifold $\mathcal{D}^{s}(\mathbb{R}^{d})$ and on the smooth regular Fréchet-Lie group of all $H^{\infty}$-diffeomorphisms is obtained. In addition a local existence result for the geodesic equation for metrics of order $\frac{1}{2} \leq s < 1 + d/2$ is derived.

Regulation of cell morphogenesis by targeted noise suppression and trafficking of a G protein alpha subunit
Creators: name: Dixit, Gauri
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: G proteins and their associated receptors form the largest class of proteins that receive and transduce chemical and sensory signals. Regulation of G proteins therefore, is critical to appropriate cellular responses. The work in this thesis evaluates a new function for a known regulator of signaling and identifies a new class of previously unknown regulators that mediate G protein trafficking. Using a yeast model system we demonstrate a novel role for the Regulator of G protein Signaling (RGS) protein in suppression of cell-to-cell variability. Furthermore we identify a novel cascade of ubiquitin-binding domain (UBDs) proteins that serve to deliver the Gα protein from the plasma membrane to the vacuole. Through biochemical assays and single cell analysis we find that the RGS and UBD proteins regulate cellular morphogenesis during signaling. More broadly through this work we were able to uncouple signal and noise in a prototypical stimulus-response pathway and demonstrate for the first time the consequences of G protein trafficking in a non-visual system. This work is important because a thorough understanding of how G protein signaling is spatially and temporally regulated will eventually lead to new drug targets, and more effective or targeted therapeutics.

description: We perform molecular dynamics simulations to understand the translational and rotational diffusion of Janus nanoparticles at the interface between two immiscible fluids. Considering spherical particles with different affinity to fluid phases, both their dynamics as well as the fluid structure around them are evaluated as a function of particle size, amphiphilicity, fluid density, and interfacial tension. We show that as the particle amphiphilicity increases due to enhanced wetting of each side with its favorite fluid, the rotational thermal motion decreases. Moreover, the in-plane diffusion of nanoparticles at the interface becomes slower for more amphiphilic particles, mainly due to formation of a denser adsorption layer. The particles induce an ordered structure in the surrounding fluid that becomes more pronounced for highly amphiphilic nanoparticles, leading to increased resistance against nanoparticle motion. A similar phenomenon is observed for homogeneous particles diffusing in bulk upon increasing their wettability. Our findings can provide fundamental insight into the dynamics of drugs and protein molecules with anisotropic surface properties at biological interfaces including cell membranes.

description: One approach to explaining the hierarchical levels of understanding within a machine learning model is the symbolic method of inductive logic programming (ILP), which is data efficient and capable of learning first-order logic rules that can entail data behaviour. A differentiable extension to ILP, so-called differentiable Neural Logic (dNL) networks, are able to learn Boolean functions as their neural architecture includes symbolic reasoning. We propose an application of dNL in the field of Relational Reinforcement Learning (RRL) to address dynamic continuous environments. This represents an extension of previous work in applying dNL-based ILP in RRL settings, as our proposed model updates the architecture to enable it to solve problems in continuous RL environments. The goal of this research is to improve upon current ILP methods for use in RRL by incorporating non-linear continuous predicates, allowing RRL agents to reason and make decisions in dynamic and continuous environments.

description: Die vorliegende Masterarbeit befasst sich mit den Themen Schulfähigkeit und schulische Lernfreude. Im ersten Teil wird der Begriff der Schulfähigkeit in der heutigen Zeit unter Rückgriff auf die Fachliteratur definiert. Diese hermeneutische Analyse zeigt auf, dass es sich bei dem Begriff der Schulfähigkeit um ein komplexes Konstrukt handelt, welches sich nicht einheitlich definieren lässt. Vielmehr wandelt sich die Begriffsbedeutung mit der Zeit und den jeweiligen Sichtweisen durch die Autorenschaft. In der Praxis weisen die theoretischen Modelle bezüglich der Schulfähigkeit zudem wenig Relevanz auf, vielmehr dominieren im Berufsalltag die subjektiven Theorien über die Schulfähigkeit und beeinflussen die Kindergartenlehrpersonen und die Lehrpersonen bei der Beurteilung der Kinder massgeblich. Im zweiten Teil geht es darum herauszufinden, warum bei einigen Kindern die anfängliche Motivation und Freude am Lernen nach dem Übertritt in die erste Klasse langsam schwinden. Für das Entstehen von schulischer Lernfreude müssen bestimmte Umwelt- und Persönlichkeitsmerkmale zusammenspielen. Diese Merkmale werden herausgearbeitet und mit dem Stufenübertritt in die erste Klasse in Verbindung gesetzt. Aufgrund der gewonnenen Erkenntnisse werden zuletzt (heil-) pädagogische Handlungsansätze für die Praxis auf den Ebenen Kind, Eltern, Kindergarten und Schule sowie Kooperationsmöglichkeiten zwischen den beiden Institutionen skizziert.
Student Engagement in Self-Contained Classrooms Serving Students with Autism Spectrum Disorders

Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: Given the rising prevalence rates of autism spectrum disorders (ASD), schools are serving an increasing number of students with ASD (Scull & Winkler, 2011). Researchers have highlighted active engagement as a critical component of effective interventions for students with ASD (National Research Council, 2001), yet there is limited research related to engagement in school-age children with ASD. Joint engagement, which reflects the social nature of engagement, is a known area of deficit in young children with ASD (Adamson, Bakeman, Deckner, & Romski, 2009) and may be an ideal construct for assessing the engagement of older students with ASD in the classroom. This descriptive study was designed to examine the relationship of joint engagement with classroom ecological factors and student characteristics. The sample included 25 elementary and middle school students with ASD served in eight self-contained special education classrooms across three different school districts. Joint engagement was measured during typical classroom instruction in individual, small group, and large group sessions using live coding procedures. Data for the independent variables included the classroom ecological factors of group size, teachers' use of student directed practices, teacher interaction style and teacher report of burnout, and the student characteristics of autism severity, expressive communication, and receptive vocabulary. Mixed level modeling was used to examine relationships between joint engagement and the independent variables. Joint engagement was significantly related to group size, teachers' use of student-directed practices, students' autism severity, and students' expressive communication skills. There were no significant relationships of joint engagement with teacher interaction styles, teacher report of burnout, and students' receptive vocabulary skills. Additionally, the consistency of joint engagement as measured by within student variance was 38%, 66%, and 82% for large group, small group, and individual contexts, respectively. These findings have important implications for educational policies and practices and future research related to active engagement and effective interventions for students with ASD.

description: The physical impossibility of heat transfer under isothermal conditions implies that the classical expression for the entropy of the ideal gas may not be compatible with the internal energy of the gas itself. A corrected expression of the ideal gas entropy is derived here. It is independent on volume. This result is shown to be at a variance with the statistical interpretations of entropy as a quantity that is related to the number of microstates compatible with the macroscopic state of the system. It also offers a better understanding of the thermodynamic notion of entropy. The present analysis also establishes a general equation that links the entropy of a system to its internal energy.

Gravitation, and quantum theory, as emergent phenomena

Year: 2023
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: There must exist a reformulation of quantum field theory, even at low energies, which does not depend on classical time. The octonionic theory proposes such a reformulation, leading to a pre-quantum pre-spacetime theory. The ingredients for constructing such a theory, which is also a unification of the standard model with gravitation, are : (i) the pre-quantum theory of trace dynamics: a matrix-valued Lagrangian dynamics, (ii) the spectral action principle of non-commutative geometry, (iii) the number system known as the octonions, for constructing a non-commutative manifold and for defining elementary particles via Clifford algebras, (iv) a Lagrangian with $E_8 \times E_8$ symmetry. The split bioctonions define a sixteen dimensional space (with left-right symmetry) whose geometry (evolving in Connes time) relates to the four known fundamental forces, while predicting two new forces, $SU(3)_{grav}$ and $U(1)_{grav}$. This latter interaction is possibly the theoretical origin of MOND. Coupling constants of the standard model result from left-right symmetry breaking, and their values are theoretically determined by the characteristic equation of the exceptional Jordan algebra of the octonions. The quantum-to-classical transition, precipitated by the entanglement of a critical number of fermions, is responsible for the emergence of classical spacetime, and also for the familiar formulation of quantum theory on a spacetime background.

Let $ρ$ be an irreducible $2$-dimensional representation of Artin type of the absolute Galois group of $F$, and $π$ a cuspidal automorphic representation of GL$_2(\mathbb A_F)$, such that the $L$-functions $L(s,ρ_v)$ and $L(s,π_v)$ agree at all (but finitely many of) the places $v$ of degree one over $k$. We prove in this case that we have the global identity $L(s,ρ)=L(s,π)$, with $ρ_v \leftrightarrow π_v$ being given by the local Langlands correspondence at all $v$. In particular, $π$ is tempered and $L(s,ρ)$ is entire.

Principal component analysis in high dimensional data: application for genomewide association studies
Creators: name: Lee, Seunggeun
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: In genomewide association studies (GWAS), population stratification (PS) is a major confounding factor which causes spurious associations by inflating test statistics. PS refers to differences in allele frequencies by disease status due to systematic differences in ancestry, rather than causal association of genes with disease. PCA is commonly used to infer population structure by computing PC scores, which are subsequently used for control of population stratification. Even though PCA is now widely used for PS adjustment, there are still challenges for PCA based effective PS control. One common feature of the genomic data is the strong local correlation among adjacent loci/markers caused by linkage disequilibrium (LD). It is known that this local correlation can have a negative effect on estimated PC scores and produce spurious PCs which do not truly reflect underlying population structure. To address this problem, we have employed a shrinkage PCA approach where coefficients are used to down-weight the contribution of highly correlated SNPs in PCA. Another challenge in PC analysis is choosing which PCs to include as covariates to adjust population stratification. While searching for a reasonable measure for PC selection, we have found the precise relationship between genotype principal components and inflation of association test statistics. Based on this fact, We propose a new approach, called EigenCorr, which selects principal components based on both their eigenvalues and their correlation with the (disease) phenotype. Our approach tends to select fewer principal components for stratification control than does testing of eigenvalues alone, providing substantial computational savings and improvements in power. Under many circumstances, it is of interest to predict PC scores. Although PC score prediction is commonly used in practice, characteristics of the predicted PC scores have not been systematically studied. Under high dimensional settings we have found that the naive predicted PC scores are systematically biased toward 0, and this phenomenon is largely due to the inconsistency of the sample eigenvalues and eigenvectors. We have extended existing convergence results of sample eigenvalues and eigenvectors and derived asymptotic shrinkage factors. Based on these asymptotic results, we propose the bias-adjusted PC score prediction.
FastMap: a fast algorithm for indexing, data-mining and visualization of traditional and multimedia datasets

description: A very promising idea for fast searching in traditional and multimedia databases is to map objects into points in k-d space, using k  feature-extraction functions, provided by a domain expert [25]. Thus, we can subsequently use highly fine-tuned spatial access methods (SAMs), to answer several types of queries, including the 'Query By Example' type (which translates to a range query); the 'all pairs' query (which translates to a spatial join [8]); the nearest-neighbor or best-match query, etc.However, designing feature extraction functions can be hard. It is relatively easier for a domain expert to assess the similarity/distance of two objects. Given only the distance information though, it is not obvious how to map objects into points.This is exactly the topic of this paper. We describe a fast algorithm to map objects into points in some k-dimensional space (k is user-defined), such that the dis-similarities are preserved. There are two benefits from this mapping: (a) efficient retrieval, in conjunction with a SAM, as discussed before and (b) visualization and data-mining: the objects can now be plotted as points in 2-d or 3-d space, revealing potential clusters, correlations among attributes and other regularities that data-mining is looking for.We introduce an older method from pattern recognition, namely, Multi-Dimensional Scaling (MDS) [51]; although unsuitable for indexing, we use it as yardstick for our method. Then, we propose a much faster algorithm to solve the problem in hand, while in addition it allows for indexing. Experiments on real and synthetic data indeed show that the proposed algorithm is significantly faster than MDS, (being linear, as opposed to quadratic, on the database size N), while it manages to preserve distances and the overall structure of the data-set.
"Acting White," "Blackness," and Education

description: Black students' fear of being accused of acting white has been offered as one reason for the achievement gap between black and white students. This thesis places the debate over Fordham and Ogbu's acting white hypothesis into the context of racial authenticities as a way to explain the contradictory conclusions of the research. Racial authenticity is then problematized using Paul Gilroy's denunciation of race presented in Against Race. The claims to blackness Gilroy finds in black popular culture along with representations of acting white are illustrated in Disney's High School Musical. Lastly, the call to give up race is situated within the context of educational research.

description: Paramylon ist ein wasserunlösliches und unverzweigtes ß-1,3-Glucan, das als Reservekohlenhydrat bei den meisten Euglenida gebildet wird. Der Paramylon-Synthase-Komplex ist ein enzymatisch aktives Protein, das in der Membran der Paramylon-Granula lokalisiert und für die Synthese des Paramylons verantwortlich ist. In der vorliegenden Arbeit wurde der Paramylon-Synthase-Komplex aus Distigma proteus und Peranema sp. durch Saccharose-Dichtegradienten- Zentrifugation isoliert und mittels Native-PAGE, SDS-PAGE und des UDP-GloTM-Glucosyltransferase-Tests charakterisiert. Der Paramylon-Synthase-Komplex der beiden Spezies ist demnach unter nativen Bedingungen ein 669 kDa großer Proteinkomplex. Bei Distigma proteus wurden mittels SDS-PAGE drei Untereinheiten im Bereich 60 kDa und zwischen 34 und 43 kDa identifiziert. Bei Peranema sp. konnte nur eine einzige Untereinheit im Bereich zwischen 50 und 70 kDa detektiert werden. Anhand von enzymatischen und chemischen Analysen wurde bestätigt, dass bei den untersuchten Spezies das Enzymprodukt Paramylon ausschließlich aus Glucose-Molekülen aufgebaut ist. Im Weiteren wurde die Transkriptomanalyse zur Feststellung der differentiellen Genexpression bei Euglena gracilis und Distigma proteus in der Licht- und Dunkelphase durchgeführt. In dieser Analyse wurden keine Veränderungen der Transkriptionslevels zwischen den beiden Wachstumsbedingungen beobachtet. Im Gegensatz zu der Transkriptomanalyse zeigten die anschließenden qPCR-Analysen, dass die Gene für den Paramylon-Synthase-Komplex (GSL 1 und GSL 2) bei Euglena gracilis unter verschiedenen Wachstumsbedingungen herunter- oder heraufreguliert werden.

description: This thesis explores how dreaming relates to waking consciousness, specifically waking mind wandering. When our minds wander, our thoughts and attention drift away from the here-and-now and move freely through various topics and themes that are to some degree unrelated to our current environment and ongoing tasks. In this thesis, I investigate and compare differences and similarities between dreaming and mind wandering, ranging from cognitive features to variations in contents. In doing so, I seek to understand whether the thoughts and imagery experienced during sleep are continuous with or distinct from what we experience when our minds wander during wakefulness.

description: The Dark Energy Survey (DES) is currently undertaking an observational program imaging $1/4$ of the southern hemisphere sky with unprecedented photometric accuracy. In the process of observing millions of faint stars and galaxies to constrain the parameters of the dark energy equation of state, the DES will obtain pre-discovery images of the regions surrounding an estimated 100 gamma-ray bursts (GRBs) over five years. Once GRBs are detected by, e.g., the Swift satellite, the DES data will be extremely useful for follow-up observations by the transient astronomy community. We describe a recently-commissioned suite of software that listens continuously for automated notices of GRB activity, collates useful information from archival DES data, and disseminates relevant data products back to the community in near-real-time. Of particular importance are the opportunities that non-public DES data provide for relative photometry of the optical counterparts of GRBs, as well as for identifying key characteristics (e.g., photometric redshifts) of potential GRB host galaxies. We provide the functional details of the DESAlert software as it presently operates, as well as the data products that it produces, and we show sample results from the application of DESAlert to several previously-detected GRBs.

The double cover of odd general spin groups, small representations and applications
Creators: name: Kaplan, Eyal
Publisher: name: arXiv

Subjects: subject: Representation Theory (math.RT)
subject: FOS: Mathematics
subject: 11F70

description: We construct local and global metaplectic double covers of odd general spin groups, using the cover of Matsumoto of spin groups. Following Kazhdan and Patterson, a local exceptional representation is the unique irreducible quotient of a principal series representation, induced from a certain exceptional character. The global exceptional representation is obtained as the multi-residue of an Eisenstein series, it is an automorphic representation and decomposes as the restricted tensor product of local exceptional representations. As in the case of the small representation of SO(2n+1) of Bump, Friedberg and Ginzburg, exceptional representations enjoy the vanishing of a large class of twisted Jacquet modules (locally), or Fourier coefficients (globally). Consequently they are useful in many settings, including lifting problems and Rankin-Selberg integrals. We describe one application, to a calculation of a co-period integral.
Mechanisms of plant immune receptor RPM1 and its associated proteins in disease resistance
Creators: name: Chung, Eui-Hwan

description: Plants evolved an immune system to recognize specific pathogens, like animals. Recognition of pathogens in plants results in series of outputs such as generation of reactive oxygen species (ROS), cell wall lignification, and a type of programmed cell death (PCD) called the hypersensitive response (HR). Plant immune receptor proteins, disease resistance (R) proteins, are the necessity for this recognition process. The R proteins mediate the plant immune response through direct or indirect recognition of pathogen effector proteins. Our previous works proposed an indirect mode of recognition explaining that R proteins can monitor the host targets (guardees) by guarding them and sense the host targets modification by pathogen effector proteins. Here I present evidence that the Arabidopsis R protein RPM1 and its interacting protein RIN4 form protein complexes in the plant in the presence/absence of bacterial effector proteins implicating that the immune response regulated by R proteins can be controlled via immune complexes. I demonstrate data for RPM1 or RIN4 containing protein complexes by size exclusion chromatography (SEC). I also present data for putative RPM1 interactors by coimmunoprecipitation-coupled liquid chromatography (LC) / mass spectrometry (MS) / MS. With the known RPM1-interacting partner, RIN4, I defined the specific mechanisms of the RPM1-mediated immune response in Arabidopsis through the phosphorylation of the residue threonine 166 in RIN4 triggered by two evolutionarily unrelated bacterial effector proteins, AvrRpm1 and AvrB. Furthermore, I found that an important residue in RIN4, phenylalanine 169, is a key for physical interaction between RPM1 and RIN4 resultant in full accumulation and activation of RPM1 in Arabidopsis.

description: Can we cluster blogs into types by considering their typical posting and linking behavior? How do blogs evolve over
time? In this work we answer these questions, by providing
several sets of blog and post features that can help distinguish between blogs. The first two sets of features focus on
the topology of the cascades that the blogs are involved in,
and the last set of features focuses on the temporal evolution, using chaotic and fractal ideas. We also propose to use
PCA to reduce dimensionality, so that we can visualize the
resulting clouds of points.

We run all our proposed tools on the ICWSM dataset. Our
findings are that (a) topology features can help us distinguish blogs, like ‘humor’ versus ‘conservative’ blogs (b) the
temporal activity of blogs is very non-uniform and bursty but
(c) surprisingly often, it is self-similar and thus can be compactly characterized by the so-called bias factor (the ‘80’ in
a recursive 80-20 distribution).

description: Die Kinderrechtskonvention (KRK) von 1989 sowie das Volksschulgesetz des Kantons Zürich (VSG, 2006) sprechen dem Kind einen gesetzlichen Anspruch auf Partizipation in allen dem Kinde betreffenden Belange zu. Dieser Anspruch lässt sich auch auf das Schulische Standortgespräch übertragen. Wahrnehmungen im beruflichen Umfeld der Autorin veranlassten diese zu der Hypothese: Je jünger das Kind ist, desto weniger erhält es die Gelegenheit, am Schulischen Standortgespräch zu partizipieren. Die vorliegende Forschungsarbeit untersucht mittels quantitativer Methode die Fragen, wie gross der Anteil aktiv teilnehmender Schülerinnen und Schüler am SSG auf der Eingangs- und Unterstufe ist und welche Gründe aus Sicht der Lehrpersonen für respektive gegen eine Teilnahme des Kindes sprechen.

Programa 5217 - CAPES/DFATD (DEPARTMENT OF FOREIGN AFFAIRS, TRADE AND DEVELOPMENT), processo 88887.343650/2019-00. O plano de atividades proposto foi finalizado. Os sinais oriundos dos sensores capacitivos sem contato direto com a pele foram devidamente pré-processados utilizando o software R Studio, o que possibilitou a extração das características desse sinal para análise posterior. O método Bootstrap e a análise PCA foram ferramentas importantes para definir os parâmetros objetivos que permitiram a comparação entre os dados dos voluntários (indivíduos saudáveis e pacientes com a DP). Os resultados e conclusões foram apresentados para o co-orientador estrangeiro e orientador brasileiro ao fim da pesquisa, com a apresentação ‘Evaluation and comparison of features extracted from wrist movement of healthy individuals and Patients with Parkinson’s Disease using capacitive sensors”. O estágio atual da pesquisa é a redação de artigo científico, intitulado “Wrist linear variability assessment with capacitive sensors in Parkinson’s Disease patients and healthy individuals”. Toda parte de programação foi feita na linguagem R usando o software R Studio. Veja informações em Anexo A – Código em R.

description: Observed rotational curves of neutral hydrogen clouds strongly support the fact that galactic halo contains huge amount of nonluminous matter, the so called gravitational dark matter. The nature of dark matter is a point of debate among the researchers. Recent observations reported the presence of ions of O, S, C, Si etc in the galactic halo and intergalactic medium. This supports the possibility of existence of electric field in the galactic halo region. We therefore propose a model of galactic halo considering this electric field arising due to charged particles as one of the inputs for the background spacetime metric. Considering dark matter as an anisotropic fluid we obtain the expressions for energy density and pressure of dark matter there and consequently the equation of state of dark matter. Various other aspects of the solutions are also analyzed along with a critical comparison with and constraints of different observational evidences.
