Estudos já apontaram para o crescente desaparecimento do pronome clítico dativo de terceira pessoa e para a substituição da preposição a pela preposição para na introdução de objeto indireto (OI) lexical no português brasileiro (PB). Tal fenômeno é identificado a partir de dados do século XIX e esses estudos, em sua maioria, partem de dados da linguagem adulta, sendo que poucos tratam deste fenômeno no âmbito escolar. Esta dissertação discute as estratégias de preenchimento do dativo no português brasileiro (PB), caracterizado pela gramática tradicional de objeto indireto, com o uso das preposições a e para, sob a forma nula e de pronome (lhe/lhes) em redações de alunos de 6º. ao 9º. ano de um colégio público e um colégio particular, da cidade de Santos. Nosso objetivo é verificar o papel da escola na recuperação das formas de prestígio e confrontar os dados encontrados com os trabalhos de Torres Morais e Berlinck (2006), Freire (2011) e Dutra (2003), os quais apontam três estratégias inovadoras: a substituição da preposição a por para, a perda progressiva dos clíticos de 3ª pessoa (lhe/lhes), que são substituídos pela forma preposicionada (a ele/eles, a ela/elas), e o aumento das formas nulas. Acima disso, espera-se, no confronto entre as produções textuais produzidas pelos alunos da escola pública e particular, indagar se há diferença na gramática internalizada de alunos que receberam diferentes estímulos linguísticos. / Several studies have pointed at the increasing disappearance of the pronoun dative clitic third person and for the replacement of the preposition a for para for the introduction of indirect object (OI) lexical in Brazilian Portuguese (PB). This phenomenon is identified from data of the nineteenth century and these studies, mostly originated from data of adult language, and few deal with this phenomenon in the school environment. This essay discusses strategies for fulfilling the dative complement in Brazilian Portuguese (BP), characterized by traditional grammar as indirect object, with the usage of the prepositions a and para and its usage as a null form and a pronoun (lhe/lhes) in 6th to 9th grade students\' compositions within a public and a private school, in Santos. Our aim is to verify the school\'s role in the rescuing of the forms of prestige and comparing the data found in the works of Torres Morais and Berlinck (2006), Freire (2011), and Dutra (2003), which point at three innovative strategies: the replacement of the preposition a for para, the progressive loss of 3rd person clitics (lhe/lhes), which are replaced for the prepositional form (a ele/eles, a ela/elas), and the increasing of null forms. Moreover, it is attempted to question if there is a difference, in the grammar internalized by students from public and private school who received different linguistic stimuli.

Districts are intermediary legislative institutions that structure the relationship between constituents and legislatures. Situated between citizens and their elected representatives, districts mediate citizen-legislator interaction, and may have wide-reaching effects on the representational relationship. By creating a political community, defining its interests by delineating its scale and boundaries, and structuring interaction between constituents and their elected representatives, districts shape the representational relationship. District characteristics alter the representational experience for constituents with very real consequences for trust in government, evaluations of legislative institutions and representatives, perceptions of responsiveness, and the degree and type of constituent-legislator communication. Three district characteristics are examined: the population size of legislative districts (constituency size), the shape of district boundaries (geographical compactness, and the extent to which district boundaries follow pre-existing political subdivision boundaries (boundary coterminousness). Using Census data and GIS, measures of these characteristics are created for every state legislative and congressional district (post-2000 redistricting) in the United States. These characteristics are combined with public opinion data to test for their influence on attitudes toward government, legislative institutions, and legislators, as well as the closeness of the representational relationship. The findings suggest constituency size is an important determinant of evaluations of government, institutions, and legislators at both the state and congressional level. The geographical districting principles of compactness and coterminousness influence the amount of constituent-legislator communication, knowledge of representatives, and in-person contact with representatives, primarily at the congressional district level. For decades, legislative districts have been drawn as if they matter only for the electoral success of legislative candidates and the partisan and racial groups those candidates represent. The primary contribution of this work is to show that districts matter beyond defining the dominant partisan or racial attributes of district constituents. Districts influence how representation is experienced by constituents.

My final thesis exhibition is directed towards children and parents. My goal is to create a connection between parent and child, and their past, present, and future through memory. Such a connection is accomplished through the implementation of these three different ideas in the artwork: 1) creating different layers of understanding, 2) producing everlasting memories, 3) connecting adult viewers to their past. In addition, I use principles as the foundation for each piece, such as the principles of kindness and learning. These principles are presented to the viewer through parables of current social and political issues, illustrated through my own cultural and artistic backgrounds. I am interested in planting good principles in the memories of the children and incentivizing parents to think about the impact the world around us has on their children.

<p>The physician -patient relationship is fundamental to medical and healthcare practice. It is value laden. The practice of medicine and healthcare in the traditional sense accentuates a fecund doctor-patient communication. This is considered a necessary step for a proper diagnosis towards an attendant fruitful prognosis. Such a practise eventuates in the recognition of core values within the ambience of a standard medical practise. The values in question refer to issues of commitment and trust, obligations to standard care giving and reception, confidentiality, autonomy, beneficence, non maleficence, justice as well as responsibility. However, the practise of medicine today is criss-crossed by an amazing cast of transformations with the advent of the internet in the medical arena. Medical encounters take place online between doctors and patients even in the absence of pre-existing medical relationships in the hospitals.</p><p>There is today treatments and medical care mediated by the internet, a case of diagnosis and prognosis across distance, and indeed super highway medicine. This instance of hospitals without consulting rooms is morally problematic.</p><p>By the characterization of physician-patient relationship ( especially in the absence of pre-existing relationship) on the internet as virtual, unique, new and problematic, this work assesses the risks associated with such encounters in the light of ethical principles and their implications for moral responsibility.</p>

<p>The purpose of this study was to: obtain and review guidelines for designing on a small screen </p><p>from several theoretic sources and to purpose own guidelines for this context. There was </p><p>chosen for the development of 3 different prototypes meant for the use on 3 different mobile </p><p>devices. Those mobile devices had a different screen size and were: an e-reader, PDA and </p><p>mobile phone. The prototypes provided the user with a future e-newspaper service (a TV </p><p>schedule). </p><p> </p><p>First design principles for good usability on small screens were abstracted from literature. </p><p>With this knowledge the three prototypes were developed. The development started with </p><p>writing down the functional and user requirements for the prototypes. After that the </p><p>developing process had two stages. The first stage was a low-fidelity prototype, this were </p><p>sketches of the graphical user interface that was commented by users. The second stage was </p><p>a high-fidelity prototype, this stage consisted of three fully functional prototypes. The three </p><p>different prototypes were used in a user evaluation. After the evaluation interviews with the </p><p>users took place to obtain additional information. </p><p> </p><p>In this research the main question was: “What are the challenges for designing the </p><p>(graphical) user interface, as a part of an e-newspaper service which is aimed at use on </p><p>multiple devices with heterogeneous screen sizes, to be recognized as the same service?”. </p><p> </p><p>The results from this research are three challenges in designing the (graphical) user interface </p><p>for devices with small screens. These challenges are: how to make the user recognize the </p><p>service in the software (recognition of service), how to develop one service on multiple </p><p>devices (use on multiple devices) and how to develop software that it is useful and pleasant </p><p>to use (usable software). In total fifteen guidelines derived from theory were found, this </p><p>research shows that thirteen of them are applicable when designing for small screens. Three </p><p>of those thirteen are reformulated in this study to make them fit better in the context. Next to </p><p>this, seven additional guidelines were proposed in this study. Examples of the purposed </p><p>guidelines are: reconstruct the layout from the non-digital service in the interface as much as </p><p>possible, explore the targeted user group, built further on their mental model and pay </p><p>attention to possible disabilities of the group, implement extra’s that give users a good reason </p><p>to use the service and make it easy for the user to select the sought information.</p>

We developed and implemented a first-principles based theory of the Landauer ballistic conductance, to determine the transport properties of nanostructures and molecular-electronics devices. Our approach starts from a quantum-mechanical description of the electronic structure of the system under consideration, performed at the density-functional theory level and using finite-temperature molecular dynamics simulations to obtain an ensemble of the most likely microscopic configurations. The extended Bloch states are then converted into maximally-localized Wannier functions to allow us to construct the Green’s function of the conductor, from which we obtain the density of states (confirming the reliability of our microscopic calculations) and the Landauer conductance. A first application is presented to the case of carbon nanotubes. / Singapore-MIT Alliance (SMA)

First principles computation can be used to investigate an design materials in ways that can not be achieved with experimental means. We show how computations can be used to rapidly capture the essential physics that determines the useful properties in different applications. Some applications for predicting crystal structure, thermodynamic and kinetic properties, and phase stability are discussed. This first principles tool set will be demonstrated with applications from rechargeable batteries and hydrogen storage materials. / Singapore-MIT Alliance (SMA)

We determined the Landauer ballistic conductance of pristine nanotubes at finite temperature via a novel scheme that combines ab-initio molecular dynamics, maximally-localized Wannier functions, and a tight-binding formulation of electronic transport in nanostructures. Large-scale ab-initio molecular dynamics simulations are used to obtain efficiently accurate trajectories in phase space. The extended Bloch orbitals for states along these trajectories are converted into maximally-localized orbitals, providing an exact mapping of the ground-state electronic structure onto a short-ranged Hamiltonian. Green's functions, self-energies, and ballistic conductance can then be obtained for any given configuration, and averaged over the appropriate statistical ensemble. / Singapore-MIT Alliance (SMA)
