I find the romance in time and space to then discuss the sociospacial segregation, the labor and peasant emigration occurred in Goiania. In addition, I discuss issues related to modernity and progress, which ended up being recurring themes in the historiography of Goiás, and I point out the ambivalence in response to the questions about the modern and nonmodern conditions of the city. Also, I highlight some aspects of leisure and politics present throughout the novel and which raise the possibility that some aspirations, found in the book, are indicative of future expectations for revealing part of its present and past. / O presente trabalho busca perceber algumas características de Goiânia, no período de sua construção, por meio da análise do romance Chão vermelho, de Eli Brasiliense, obra escrita e ambientada nessa cidade na década de 50 do século passado. Localizo o romance no tempo e no espaço para em seguida discutir a segregação socioespacial verificada em Goiânia, o trabalho e a emigração campesina. Além disso, abordo questões relativas ao moderno e ao progresso, que acabaram sendo temas recorrentes na historiografia goiana, e aponto a ambivalência como resposta ao questionamento sobre a condição moderna ou não da cidade. Destaco alguns aspectos do lazer e da política presentes no conjunto do romance e que suscitam a hipótese de que algumas aspirações, impressas na obra, são indicativos de expectativas de futuro ao revelarem parte de seu presente e passado.

Modern solid state chemistry is inconceivable without theoretical treatment of solids thanks to the availability of efficient and accurate computational methods. Being developed mainly by physicist's community and deeply rooted in the formalism of reciprocal space, they often lack connections to familiar chemical concepts, indispensable for the chemical understanding of matter. Quantum chemical topology approach is a powerful theory able to efficiently recover chemical entities from the abstract description of a system given by its density matrices. It can be used to partition any many-electron system into the atoms, using the topology of electron density or for instance into atomic shells, using the topology of ELI-D field. Various characteristics of interactions between these chemical building blocks can be obtained applying bonding indicators, e.g. from the analysis of domain-averaged properties. Quantum chemical topology methods have been extended in the current work for the applications on the diversity of theoretical methods widely used for the description of solids nowadays – from the mean field Kohn-Sham density functional theory to the reduced one-electron density matrices functional theory or from the scalar-relativistic methods to the many-component formalisms employing spinor wavefunctions. It has been shown, that they provide chemically meaningful description of the bonding which is universally applicable to any class of extended systems, be it ionic insulator, covalent solid or metal. It has been shown, that the relativistic effects on the chemical bonding can be easily revealed using extensions of bonding indicators developed in the current work. Classical chemical concepts like Zintl-Klemm concept can be easily recovered with these descriptions. Intimate connection between the class of the material and the degree of chemical bonding delocalization has been also established. All these methods have been successfully applied to the various classes of solids and delivered novel insights on their crystal structure, properties, solid state transitions and reactivity.

The thesis analyses the process of pair annihilation into one photon in a laser pulse. The theory of how to include pulse shapes in Strong Field QED and the resulting cross section is presented. The cross section is calculated and estimated for lasers of ELI and XFEL facilites. It is found that the effect may be experimentally verifiable at high frequency XFEL facilities for very finely tuned particle kinematics, but negligible at high intensity optical laser facilities such as ELI.

In this paper the compositional issues and techniques employed in my D.Mus. Thesis Composition Noite dos Tambores Silenciosos (for symphony orchestra) are discussed. The piece, constituted of three linked parts, exhibits a counterpoint of three distinct kinds of music as the main vehicle of the musical discourse. / Two of these musics are connected with Maracatu de Baque Virado and Maracatu Rural, popular musical manifestations found in Pernambuco, a state in northeast Brazil. In a "defragmentation" process, reference materials from the Maracatus are abstractly fragmented and reconstructed according to a technique I call Zin-Zout, implementing in the music a continuous state of transformation, back and forth between micro and macro dimensions. The third kind of music, free of folk references, follows a transformational process built up according to a "palimpsest" technique. In this transformation the hierarchy of the musical parameters changes along with the units of the musical content. / These procedures involve not only pitch and rhythm, but also other parameters like timbre, density and register in a structural way, as building elements of the content and form of the work. / The defragmentation process establishes some predetermined compositional paths, but permits micro- and macro-level decisions based on intuitive considerations, especially in the manipulation of orchestration and micro rhythms. More systematic, the organization of pitch involves a limited serialism and a variety of modal treatment.

There have been a number of studies that examine how public relations professionals respond during a crisis including use of traditional legal response and traditional public relations response strategies. The degree of use of either can be influenced by the relationship between legal and public relations professionals. Thus, a pre-crisis relationship between the two groups is important for successful crisis communications. The purpose of this study was to examine media coverage of the Missouri drug dilution case to determine how many of Eli Lilly and Company's public relations messages were carried by the three major media outlets covering the crisis, if there was a difference among the outlets, and whether there was a significant difference in response strategy messages were reported.A content analysis of articles during the crisis period from the Indianapolis Star, the Kansas City Star, and The Associated Press were obtained through a Factiva search and were used to gather responses made by spokespersons. The search yielded 64 usable articles and 254 sentences from company spokespersons.Coders were trained to identify the response strategies defined as traditional public relations strategy, traditional legal strategy, mixed strategy and diversionary strategy. A chi-square test was used to test the hypotheses.The first hypothesis which stated "the number of sentences attributed to Lilly spokespersons in The Indianapolis Star, The Kansas City Star, and the Associated Press in the Missouri drug dilution case will differ significantly" was supported. The second hypothesis which stated "there will be a significant difference in response strategy sentences as defined by Fitzpatrick and Rubin and attributed to Lilly spokespersons in The Indianapolis Star, The Kansas City Star, and the Associated Press during different time periods of the case" was also supported. / Department of Journalism

The main focus of this work was to investigate substitution effects on the chemical bonding in compounds of AlB 2 -type and related structure types. Delocalization indices within the QTAIM approach and the topological analysis of the ELI functionals were used as tools to describe the bonding situation in digallides and diborides. Digallides of AlB 2 -type were found only within group I and II; for CaGa 2 (meta-stable phase), SrGa 2 , BaGa 2 , YGa 2 and LaGa 2 compounds. Within these compounds, QTAIM analysis showed similar trend as previously found in diborides. That is, along the period in the Periodic Table, metal-triel interactions increase at the expense of in-plane (triel-triel) ab interactions (Tr=triel). However, transition metal diborides adopt the AlB 2 -type up to group VI. To understand this difference, we simulated transition metal (TM) digallides and diborides up to group VI in the AlB 2 -type. Additionally, the puckered variants diborides ReB 2 and OsB 2 were also simulated in the AlB 2 -type. With filling of d shell, there is a delicate balance between increase of TM–Tr and decrease of in-plane (Tr–Tr) ab electron sharing. This balance is maintained as long as interlayer interactions in the c direction (Tr–Tr ) c and (TM–TM ) c are not relatively too high in comparison to in-plane electron sharing. In contrast to TM B 2 of AlB 2 -type, digallides in the same structure type build up strong interlayer interactions for early transition metal elements. Our results showed that within digallides, a relatively strong increase in interlayer electron sharing (Ga–Ga) c and (TM–TM ) c takes place. Such increase occurs already for ScGa 2 and TiGa 2 . On the other hand, diborides show a steady increase in electron sharing of TM –B and (TM–TM ) c , but not of (B–B) c . Therefore, it is reasonable to suggest that diborides will tend to adopt a 3D network composed of boron and transition metal atoms (ReB 2 and RuB 2 types). The additional high (Ga–Ga) c interlayer interactions indicate a tendency for digallides to form 3D networks composed only by gallium atoms, characteristic of CaGa 2 (CaIn 2 -type) and ScGa 2 (KHg 2 -type). The counterbalancing bonding effects of in-plane and out-of-plane interactions that give the chemical flexibility of the AlB 2 -type in diborides is thus disrupted in AlB 2 -type digallides by a further enhanced degree of interlayer interactions (Ga–Ga) c and (TM –TM ) c . This results in a smaller number of digallides than that of diborides in AlB 2 -type. The most conspicuous difference between diborides and digallides of AlB 2 -type is in the representation of the B – B and Ga – Ga bonds revealed by the ELI- D topology. Whereas AlB 2 -type diborides exhibit one ELI-D attractor at the B – B midpoint, AlB 2 -type digallides exhibit two ELI-D attractors symmetrically opposite around the Ga – Ga bond midpoint. We utilized the E 2 H 4 (E=triel, tetrel ) molecular series in the D 2h point group symmetry as model systems for solid state calculations. In particular, we addressed the appearance of ELI- D double maxima for Ga – Ga, by using orbital decomposition within the ELI framework. The ELI-D topology changes along the 13th group T r 2 H 4 series. Whereas B 2 H 4 and Al 2 H 4 exhibit one ELI-D attractor representing the Tr–Tr bond, Ga 2 H 4 and In 2 H 4 give rise to two ELI-D attractors. Partial ELI-D allows the orbital decomposition of the electron density. Partial ELI-q gives access to the decomposition of a two-particle property, which is given by the Fermi-hole curvature. We have found that the d-orbitals enable the formation of the two ELI-D attractors through pairing contributions. This has a net effect of lowering electron localizability at the Ga – Ga bond midpoint. Namely, the different ELI-D topology of Ga – Ga and B – B bonds stems from the contributions of d-orbitals to orbital pairing. We have also investigated the bonding situation in transition metal diborides of ReB 2 -type (MnB 2 , TcB 2 , ReB 2) and RuB 2 -type (OsB 2 , RuB 2). One can consider these two structure types as an extension of the trend found in TM B 2 of AlB 2 -type: an increase in TM –B interactions and an enhanced three-center bonding. The change in the structure type results in a puckered layer of boron atoms with electrons equally shared between B – B and TM –B. However, TM –B bonds exhibit a high three-center character. The ELI-D/QTAIM intersection technique also revealed a high participation of TM in the B – B bonding basin population. Moreover, ELI-D topology in the ReB 2 -type also discloses a seemingly important Re 3 three-center interaction along the flat layer of Re atoms. Such basin is absent in MnB 2 , which coincides with the fact that MnB 2 was only observed in the AlB 2 -type. In this regard, we concluded that the 3D network consists not only of covalent B – B bonds, but also of TM –B bonds.
