Texting while driving is a growing problem that has serious, and sometimes fatal, consequences. Despite laws enacted to curb this behavior, the problem continues to grow. Discovering factors that can reduce such risky behavior can significantly contribute to research, as well as save lives and reduce property damage. This study developed a model to explore the motivations that cause a driver to send messages. The model evaluates the effects that boredom, social relationships, social anxiety, and social gratification (BRAG) have upon a driver’s frequency of typing text messages. In addition, the perceived severity of the consequences and the presence of a passenger were also be evaluated for any moderating effects on a driver’s texting. Furthermore, a set of hypotheses based on the BRAG model were presented. To investigate these hypotheses, a survey instrument was developed and data was collected from 297 respondents at a mid-sized regional university in the Pacific North west of the United States. Prior to the distribution of the survey, an expert panel and a pilot study were used to ensure the reliability of the instrument. Partial least squares structured equation modeling (PLS-SEM) was used to evaluate the predictive validity of the BRAG model. This evaluation included an assessment of the reflective measures, as well as a detailed analysis of the structural model. Additionally, knowledge visualization techniques were used to emphasize the significance of the findings. The results of this analysis showed that the social gratification one receives from maintaining their social relationships is a significant predictor of texting while driving. Additionally, the results showed that drivers continued to text, regardless of the consequences. However, boredom and social anxiety were not significant predictors of texting while driving. This study makes important contributions to the information systems body of knowledge and has implications for state and local lawmakers, in addition to public health officials. Prior research has shown that bored or anxious individuals use texting to relieve those feelings of discomfort. However, this study did not extend those findings to drivers. As this study found that laws banning texting while driving do not deter this behavior, public health officials and lawmakers should investigate other means of deterring texting while driving, given the significant impact it has on the increase of fatal car accidents in recent years.

Brown, Ph.D., co-directeur de recherche / Objectifs : La capacité en matière de prise de décisions des récidivistes de conduite avec capacités affaiblies (CCA) semble les distinguer des non-contrevenants, particulièrement dans des situations ambiguës à haut risque, telles que la CCA. Cette étude exploratoire vise à vérifier l’hypothèse selon laquelle les récidivistes de CCA (R) auraient une moins bonne capacité de prise de décisions et une plus faible réponse de conductibilité électrodermale par anticipation à la tâche Iowa Gambling Task (IGT) que les non-contrevenants (C). Méthode : Vingt-trois récidivistes et 24 non-contrevenants ont été recrutés. Leur âge moyen (± É.T.) était 44.17(10.03) et 37.29 (10.60) ans respectivement. Les participants devaient être âgés de 18 ans ou plus, et avoir eu deux condamnations pour CCA ou plus pour le groupe R, et zéro CCA et un permis de conduire pour le groupe C. Les participants ont effectué I’IGT, une tâche neurocognitive de prise de décisions comprenant 100 sélections de cartes divisées en cinq blocs pour les analyses. On a comparé la performance du groupe R versus le groupe C à l’aide d’une ANOVA à mesures répétées [2 (groupe) x 5 (blocs)]. On a évalué la performance durant les blocs 1 & 2 (décisions dans l’ambiguïté) et blocs 3-5 (décisions sous haut risque) en utilisant des tests t post-hoc. Finalement, on a mesuré leur réponse de conductibilité électrodermale (RCEA) durant l’IGT. Résultats : L’ANOVA à mesures répétées des blocs 1 à 5 a révélé un effet significatif de l’interaction groupe par bloc, F(1,45)=5.28, p=.03, état carré =.11. Les tests t post hoc ont révélé une différence significative entre les groupes pour la combinaison des blocs 3 à 5, t(45) = 3.38, p = .002. Un effet d’interaction significatif a été détecté pour la RCEA des récidivistes de CCA versus celle des non-contrevenants, F(8,160)=2.33, p=.02, état carré =.10. Conclusion : Les récidivistes de CCA performent moins bien que les non-contrevenants à l’IGT. Ils persistent à prendre des décisions basées sur le potentiel de gains immédiats et négligent donc les risques de pertes. Ceci suggère qu’ils ont des déficits en matière de prise de décision, ce qui, en tant que groupe, les différencie des non-contrevenants. Une difficulté en matière de prise de décisions pourrait expliquer en partie le comportement impulsif fréquemment associé au récidivisme de CCA. Finalement, puisque les analyses de RCEA manquaient de puissance statistique, il est possible que de plus grands échantillons puissent permettre d’observer des différences entre les groupes de participants dans l’analyse de RCEA. / Objectives: Poor decision making in ambiguous high-risk situations, such as driving while impaired (DWI) by alcohol, may differentiate DWI recidivists from non-offenders. In this study, we test the hypothesis that DWI recidivists (R) will exhibit poorer decision-making performance on the Iowa Gambling Task (IGT), and in line with the Somatic Marker Hypothesis, weaker anticipatory somatic activation (using skin conductance response as index) than non-offenders (C, comparison group). Methods: DWI recidivists and non-DWI control drivers were recruited, [R (n=23) and C (n=24), mean ages (± SD) 44.17(10.03) and 37.29 (10.60) years respectively]. Participant selection criteria included ≥ 18 years old and ≥2 DWI convictions for group R and 0 DWI convictions lifetime and a driver’s license for group C. The participants performed the IGT, a decision-making neurocognitive task containing 100 card selection trials that we divided into 5 blocks for analyses. A 2 (group) x 5 (blocks) repeated measures ANOVA was used to compare group R performance on the IGT versus group C, followed by post hoc independent t-tests on aggregated blocks 1-2 (decision under ambiguity) & 3-5 (decision under high risk) to identify the source of group X block significant interactions. Two 3 (group) x 5 (blocks) repeated measures ANOVAs (for good decks and for bad decks) were used to compare the aSCR of groups C and R. Results: ANOVA repeated measures on blocks 1 to 5 produced a significant effect of group by block interaction F(1,45)=5.28, p=.03, partial ƞ2 =.11. Post hoc t-tests on aggregated blocks 3 to 5 were statistically significant, t(45) = 3.38, p = .002. A significant group x block interaction effect was found for good decks aSCR, F(8,160)=2.33, p=.02, partial ƞ2 =.10 . Conclusion: DWI recidivists performed more poorly than controls on the IGT, persistently making decisions based on potential immediate gains and neglecting associated loss risks and long-term outcome. This suggests they have reduced neurocognitive decision-making capacities distinguishable from the general population. While DWI recidivists’ behaviour appears as impulsive, these results suggest that their behaviour pattern involves decision-making difficulties. Larger sample sizes may be needed to detect a between-group effect in the aSCR analyses, as they were considerably underpowered.

The work presents a study regarding the development of rules of conduct existing in the international system for cases of intervention, emphasizing the normative evolution of UN peacekeeping operations and the concept of Responsibility to Protect (R2P). It details the Brazilian proposal, with its many points of contact with the aforementioned concept and its reception in the international system through the analysis of statements issued by the United Nations, representatives of NGOs, IOs and civil society organizations. It also discusses about the major foreign policy biases adopted by the Brazilian government from 1990 to 2014, through the analysis of the speeches of the national delegation to the General Assembly and the UN Security Council. Therefore, it is able to verify that the RWP presents no major outbreaks of incongruity with the R2P—dating back to the standard ratified by the United Nations for the construction of most of its normative basis—and is extremely consistent with the lines of foreign policy adopted by Brazil over the past 24 years. / Este trabalho visa verificar se a Responsabilidade ao Proteger (RwP) representa inovação no posicionamento do Brasil nos foros onusianos, bem como sua compatibilidade com as estratégias de política externa do país, detalhando seus aspectos inovadores e explicitando em quais ocasiões anteriores tais propostas e posições surgiram enquanto argumento do próprio país ou de terceiros. Para tanto, realiza um estudo sobre o desenvolvimento das normas de conduta vigentes no sistema internacional para os casos de intervenção, com ênfase na evolução normativa das operações de paz da ONU e no conceito da Responsabilidade de Proteger (R2P). Detalha a proposta brasileira, apresentando seus—muitos—pontos de contato com o supracitado conceito e sua recepção no sistema internacional, através da análise de declarações emitidas por membros das Nações Unidas, representantes de ONGs, OIs e organizações de sociedade civil. Versa, ainda, sobre os principais vieses de política externa adotados pelos governos brasileiros no período de 1990 a 2014, por meio a análise dos discursos da delegação nacional na Assembleia Geral e no Conselho de Segurança das Nações Unidas. Sendo assim, é possível verificar que a RwP não apresenta grandes focos de incongruência com a R2P—remontando à norma ratificada pelas Nações Unidas para a construção da maior parte de seu embasamento normativo—e é extremamente coerente com as linhas de política externa adotadas pelo Brasil ao longo dos últimos 24 anos.

This thesis provides a feasibility study on the determination of formation anisotropy parameters from logging-while-drilling (LWD) borehole acoustic measurements. For this reason, the wave propagation in fluid-filled boreholes surrounded by transverse isotropic (TI) formations is investigated in great detail using the finite-difference method. While the focus is put on quadrupole waves, the sensitivities of monopole and flexural waves are evaluated as well. All three wave types are considered with/without the presence of an LWD tool. Moreover, anisotropy-induced mode contaminants are discussed for various TI configurations. In addition, the well-known plane wave Alford rotation has been generalized to cylindrical borehole waves of any order, except for the monopole. This formulation has been extended to allow for non-orthogonal multipole firings, and associated inversion methods have been developed to compute formation shear principal velocities and accompanying polarization directions, utilizing various LWD (cross-) quadrupole measurements.:1 Introduction 1.1 Borehole acoustic configurations 1.2 Wave propagation in a fluid-filled borehole in the absence of a logging tool 1.3 Wave propagation in a fluid-filled borehole in the presence of a logging tool 1.4 Anisotropy 2 Theory 2.1 Stiffness and compliance tensor 2.1.1 Triclinic symmetry 2.1.2 Monoclinic symmetry 2.1.3 Orthotropic symmetry 2.1.4 Transverse isotropic (TI) symmetry 2.1.5 Isotropy 2.2 Reference frames 2.3 Seismic wave equations for a linear elastic, anisotropic medium 2.3.1 Basic equations 2.3.2 Integral transforms 2.3.3 Christoffel equation 2.3.4 Phase slowness surfaces 2.3.5 Group velocity 2.4 Solution in cylindrical coordinates for the borehole geometry 2.4.1 Special case: vertical transverse isotropy (VTI) 2.4.2 General case: triclinic symmetry 3 Finite-difference modeling of wave propagation in anisotropic media 3.1 Finite-difference method 3.2 Spatial finite-difference grids 3.2.1 Standard staggered grid 3.2.2 Lebedev grid 3.3 Heterogeneous media 3.4 Finite-difference properties and grid dispersion 3.5 Initial conditions 3.6 Boundary conditions 3.7 Parallelization 3.8 Finite-difference parameters 4 Wave propagation in fluid-filled boreholes surrounded by TI media 4.1 Vertical transverse isotropy (VTI) 4.1.1 Monopole excitation 4.1.2 Dipole excitation 4.1.3 Quadrupole excitation 4.1.4 Summary 4.2 Horizontal transverse isotropy (HTI) 4.2.1 Monopole excitation 4.2.2 Theory of cross-multipole shear wave splitting 4.2.3 Dipole excitation 4.2.4 Quadrupole excitation 4.2.5 Hexapole waves 4.2.6 Summary 4.3 Tilted transverse isotropy (TTI) 4.3.1 Monopole excitation 4.3.2 Dipole excitation 4.3.3 Quadrupole excitation 4.3.4 Summary 4.4 Anisotropy-induced mode contaminants 4.4.1 Vertical transverse isotropy (VTI) 4.4.2 Horizontal transverse isotropy (HTI) 4.4.3 Tilted transverse isotropy (TTI) 4.4.4 Summary 5 Inversion methods 5.1 Vertical transverse isotropy (VTI) 5.2 Horizontal transverse isotropy (HTI) 5.2.1 Inverse generalized Alford rotation 5.2.2 Inversion method based on dipole excitations 5.2.3 Inversion method based on quadrupole excitations 5.3 Tilted transverse isotropy (TTI) 5.4 Challenges in real measurements 5.4.1 Signal-to-noise ratio (SNR) 5.4.2 Tool eccentricity 6 Conclusions References List of Abbreviations and Symbols List of Figures List of Tables A Integral transforms A.1 Laplace transform A.2 Spatial Fourier transform A.3 Azimuthal Fourier transform A.4 Meijer transform B Stiffness and compliance tensor B.1 Rotation between reference frames B.2 Cylindrical coordinates C Christoffel equation C.1 Cartesian coordinates C.2 Cylindrical coordinates D Processing of borehole acoustic waveform array data D.1 Time-domain methods D.2 Frequency-domain methods D.2.1 Weighted spectral semblance method D.2.2 Modified matrix pencil method

Durant les dernières décennies, les différences intersexes en matière de conduite avec les capacités affaiblies par l’alcool (CCAA) ont suscité l’attention, alors que le comportement est en augmentation chez les femmes tandis qu’il diminue chez les hommes. Les données suggèrent que, chez les femmes, la CCAA s’associe à des caractéristiques psychologiques différentes de celles qui se retrouvent chez les contrevenants masculins (c.-à-d. davantage de problèmes liés à l’alcool et aux drogues et de psychopathologies, mais moins de recherche de sensations et de comportements délinquants). Malgré ce profil différentiel, les femmes contrevenantes de la CCAA demeurent une population hautement méconnue, particulièrement en ce qui a trait au profil des récidivistes. Alors que chez les hommes, des données émergentes indiquent que des limitations cognitives sont présentes chez les récidivistes et qu’elles constituent potentiellement un mécanisme sous-jacent au comportement, le profil cognitif des femmes récidivistes demeure inexploré. Des données exploratoires obtenues chez les contrevenantes et la documentation de champs de recherche connexes suggèrent que les femmes se distinguent notamment en ce qui concerne leur fonctionnement exécutif qui pourrait être préservé, alors que leur fonctionnement visuospatial serait déficitaire en comparaison de leurs vis-à-vis masculins. L’objectif de la présente thèse est d’approfondir les connaissances sur les caractéristiques des femmes récidivistes, ce qui permettra de mieux comprendre l’hétérogénéité de cette population et de générer des hypothèses au regard des mécanismes cognitifs sous-jacents à la répétition du comportement de CCAA. Plus spécifiquement, la thèse a pour objectif premier d’étudier les différences entre les sexes en matière de fonctionnement visuospatial et de mémoire visuelle, d’attention et de fonctionnement exécutif (c.-à-d. flexibilité cognitive, abstraction, inhibition). L’objectif secondaire consiste à comparer ces contrevenants au regard de leurs caractéristiques psychologiques (problèmes liés à l’alcool et aux drogues, impulsivité, recherche de sensations, traits antisociaux, anxiété et dépression). L’hypothèse examinée soutient que les femmes et les hommes récidivistes de la CCAA performent moins bien que les femmes et les hommes non-contrevenants en termes de fonctionnement visuospatial, attentionnel et exécutif. En outre, il est attendu que les femmes récidivistes présentent des performances inférieures à celles des hommes récidivistes en ce qui a trait aux fonctions visuospatiales. Par ailleurs, l’hypothèse prévoit que les hommes récidivistes aient des performances inférieures à celles des femmes récidivistes sur le plan exécutif et attentionnel. En matière de caractéristiques psychologiques, il est attendu que les femmes et les hommes récidivistes présentent significativement plus de problèmes liés à l’alcool et aux drogues, d’impulsivité, de recherche de sensations et d’indices de psychopathologies (tendance antisociale, dépression, anxiété) que les non-contrevenants. En outre, il est attendu que les femmes récidivistes présentent plus de problèmes liés à l’alcool et aux drogues et d’indices de dépression et d’anxiété que les hommes récidivistes. Enfin, il est attendu que les hommes récidivistes présentent significativement plus d’impulsivité, de recherche de sensations et de traits antisociaux que les femmes récidivistes. Ces hypothèses se confirment partiellement, alors que les hommes récidivistes (n = 39) présentent des performances inférieures à celles des hommes non-contrevenants (n = 20) et des femmes récidivistes (n = 20) sur le plan attentionnel et exécutifs. Toutefois, les femmes récidivistes ne se distinguent pas des femmes non-contrevenantes (n = 20) en matière de fonctionnement neuropsychologique. En ce qui a trait aux caractéristiques psychologiques, les résultats soutiennent partiellement les hypothèses. La discussion met en lumière que les femmes et des hommes récidivistes présentent des caractéristiques similaires, hormis en ce qui a trait au fonctionnement attentionnel et exécutif qui semble jouer un rôle dans la récidive au masculin, alors que cela n’apparaît pas être le cas chez les femmes chez qui le comportement pourrait être davantage situationnel. La nécessité que des études futures soient réalisées au moyen de devis expérimentaux, de même que les difficultés inhérentes au recrutement des femmes récidivistes sont discutées. / During the past decade, female driving while impaired by alcohol (DWIA) have gathered more attention as DWIA is increasing in females while decreasing in males. Data suggest that DWIA risk in females is associated with distinct psychological characteristics from those of male offenders (i.e. more alcohol and drug-related problems, and psychopathology, while less sensation seeking and delinquency). Despite this differential profile, female DWIA offenders remain a highly unknown population, especially regarding recidivism. In addition, growing data, mostly based on male offenders, support the idea that cognitive limitations are present in recidivists and represent a potential underlying mechanism to their behavior. Exploratory data collected in female offenders and data from other germane research fields suggest that female recidivists are cognitively distinct, especially in terms of executive functioning that could be relatively spared while their visuospatial functioning would be more impaired in comparison of male offenders. The objective of this dissertation is to enhance knowledge on female recidivist’s characteristics. This will allow a better comprehension of the heterogeneity of DWIA recidivist’s population and generate hypotheses concerning potential mechanisms that underlie their repetitive DWIA behavior. The thesis is especially targeting neuropsychological and psychological characteristics of female recidivists. More specifically, the study’s first aim is to examine DWIA recidivists sex differences regarding visuospatial functioning, attentional and executive functions (i.e. cognitive flexibility, abstraction, inhibition). The secondary objective is to compare offenders on psychological characteristics (alcohol and drug use, impulsivity, sensation seeking, anxiety, depression and antisocial tendencies). It is hypothesized that female and male DWIA recidivists would present a lower performance than their respective non-offender counterparts in terms of visuospatial, attentional and executive functions. In addition, it is expected that female recidivists would present a lower visuospatial performance than male recidivists. It is also hypothesized that male recidivists would exhibit lower attentional and executive performances than female recidivists. Regarding psychological characteristics, it is expected that recidivists would present more alcohol and drug-related problems, impulsivity, sensations seeking and psychopathology (antisocial tendencies, depression, anxiety) than non-offenders and that female recidivists would present more alcohol and drug-related problems, depression and anxiety than male recidivists. Finally, hypotheses suggest that male recidivists would present more impulsivity, sensations seeking and antisocial tendencies than female recidivists. These hypotheses are partially supported as male recidivists (n = 39) present lower attentional and executive performances than male non-offenders (n = 20) and female recidivists (n = 20). However, female recidivists do not significantly differ from female non-offenders (n = 20) in terms of neuropsychological functioning. In regard to psychological characteristics, results partially support hypotheses. The discussion highlights female and male similar characteristics except for attentional and executive mechanisms that seem to play a role in male recidivism, while it is apparently not the case in female recidivists whose behavior could be more situational. The need for further studies with experimental design as well as difficulty in female recruitment are discussed.

This thesis Methodology of playing the flute of children from 4 to 6 years deals with the problem of learn to play the flute preschool children. The theoretical part deals with the importance of this activity, its contribution to the children themselves. It focuses on the developmental characteristics of this period, the physical and mental maturity, the skills needed for learning to play flute. It also compares the methodology and the methodology of music education games on the soprano recorder for children of school age and younger children. The practical part deals with the specific methodology you learn to play the soprano flute - using the "color music". Describes the formation method, its advantages for the acquisition of flute playing children 4 to 6 years, application of methods in teaching and, not least, textbook design, the concept would be based on this method.

The main aim of this research was to explore lecturers’ and students’ perceptions of the effectiveness of teaching listening skills to English foreign language (EFL) students at three Ethiopian universities with the purpose of proposing guidelines and recommendations for effective teaching and learning of EFL listening skills. The research was prompted by a number of research projects which indicated that listening skills and the teaching of listening in the Ethiopian context were not effective resulting in students who are ill equipped for listening effectively. A mixed method approach was followed as a design for the empirical research study. A pragmatic research paradigm, using both quantitative and qualitative methods and then blending the two methods was employed. Quantitative data were collected from 72 lecturers and 158 students at three Ethiopian universities by means of close-ended questionnaires using a five-point Likert scale instrument. For the qualitative phase of the study data were collected by means of semi-structured interviews with lecturers and students. Observations of listening lessons presented in the classroom and in the language laboratory were done by means of completing an observation checklist and note-taking. These were used to triangulate data. The analysis of the data obtained by means of the questionnaires and the observation checklist were done using descriptive and inferential statistics. Qualitative data obtained by means of unstructured interviews (which were transcribed verbatim) were coded and divided into themes. The research findings indicated that the lecturers’ perceptions of the activities used during the pre-, while- and post-listening phases and the use of listening material were more positive than those of students and that females perceived the effectiveness less positive than males. The data obtained by means of interview questions confirmed what was found in the quantitative part of the study. Observations carried out in the three universities showed that the teaching of listening skills was mostly poorly done and that the listening material used was not suitable and did not interest students. The use of bottom-up and top-down strategies were found to be used inadequately in the teaching of EFL listening skills. The teaching methods and strategies used, as well as activities provided during each listening phase were found to be generally poor. A model for teaching EFL listening in the classroom was proposed in this study. Lecturers and students expressed their challenges in teaching and learning EFL listening skills and also made recommendations for best practices on how to improve the teaching and learning of EFL listening. These challenges and recommendations for best practices mostly centred around lecturer-related, student-related and institutional-related factors. This study has suggested recommendations pertaining to the lecturers, students, institutions of higher education, the Ethiopian Ministry of Education and schools. / Curriculum and Instructional Studies / D.

The analysis of the rules evolution, in particular internationally, demonstrates normative and principles conflicts that serve as power play instrument and the colonizer-colonized dichotomy, even when its essence is directed to the maintenance of peace. The the Responsibility While protecting (RWP) presented by Brazil in 2011, within the context of the development of global standards, permeated by non-linear conflictual interactions, where the interventions based on a Responsibility to Protect(R2P) civilians, have challenged the existing structures in the global order and therefore has sparked great debate regarding the prevalence of decisions emanating from the United Nations Security Council - UNSC against the sovereignty and self-determination of peoples, since there is no control of legality and legitimacy of that discretion which the United Nations - UN holds. In this sense, the present work aims to analyze if the Responsibility to Protect can be considered as an attempt to influence from the Global South countries in the production of global standards and this can work as a capable principle of safeguarding the coercive nature of measures by of the UNSC, a way of accountability that implies a large extent by the level of responsibility of emanating acts from the UN Security Council that determ interventions, and what tools are needed for the Responsibility to Protect is an effective tool of prior control of legality and legitimacy. In order to meet this goal, we adopted a dialectical approach, drawing on the monographic method, through bibliographical and documentary research and interdisciplinary literature, among others that apply to the subject under study. / A análise da evolução das normas, em específico no âmbito internacional, demonstra conflitos normativos e principiológicos que servem de instrumento de reprodução de poder e da dicotomia colonizador-colonizado, mesmo quando sua essência está voltada para a manutenção da paz. O Princípio da Responsabilidade ao Proteger (RWP, sigla em inglês), apresentado pelo Brasil em 2011, surge no contexto da evolução das normas globais, permeadas por interações não lineares conflituosas, onde a implementação cada vez maior de intervenções baseadas em uma Responsabilidade de Proteger (R2P, sigla em inglês) civis, tem desafiado as estruturas existentes na ordem global e por isso tem suscitado grande debate no que toca a prevalência de decisões emanadas do Conselho de Segurança das Nações Unidas - CSNU face à soberania e a autodeterminação dos povos, uma vez que não há um controle de legalidade e legitimidade desse poder discricionário do qual a Organização das Nações Unidas - ONU é detentora. Nesse sentido, a presente dissertação visa analisar se a Responsabilidade ao Proteger pode ser considerada como uma tentativa de influência a partir dos países do Sul Global na produção de normas globais e se esta pode funcionar como um princípio capaz de acautelar as medidas de natureza coercitiva por parte do CSNU, isto é, uma forma de accountability que implique em um maior nível de responsabilidade por parte dos atos emanados do Conselho de Segurança da ONU que determinem intervenções, bem como quais são os instrumentos necessários para que a Responsabilidade ao Proteger seja uma ferramenta eficaz de controle prévio de legalidade e legitimidade. De forma a cumprir esse objetivo, adotou-se uma abordagem dialética, valendo-se do método monográfico, por meio de pesquisa bibliográfica e documental e literatura especializada interdisciplinar, dentre outras que aplicáveis ao tema em estudo.
