Este trabalho tem como proposta analisar a regra prevista no art. 147, § 3º, da Lei das S.A., e compreender a efetiva extensão do interlocking board e seus impactos para a vida das companhias brasileiras. Com base na análise dos motivos que levaram à inclusão desse dispositivo, propõe-se uma nova abordagem interpretativa. Afasta-se uma concepção abrangente da hipótese de conflito de interesses contemplada no inciso II ou a interpretação autônoma da atuação em sociedade considerada concorrente, independentemente da existência de conflito de interesses. A proposta interpretativa, nesse sentido, aponta para a complementaridade dos dispositivos, de forma que ocorra o impedimento quando o conselheiro atuar em sociedade concorrente e, em decorrência disso, tiver interesse conflitante com o da companhia. Propõe, da mesma forma, um novo enfoque para o estudo das situações de conflito de interesses entre os administradores e a companhia, sugerindo uma desvinculação das conclusões obtidas com a análise do conflito de interesses do acionista (art. 115, § 1º) para aceitar a possibilidade de uma análise a priori do conflito de interesses entre o administrador e a companhia, ainda que identificável por critérios substanciais. / This work intends to study the Article 147, Paragraph 3, of the Brazilian Corporate Law (Law 6.404/76), and understand the actual extension of interlocking board and their impacts on the Brazilian companies. Based on the study of the reasons that led to the inclusion of this Article during Brazilian Corporate Law changes during the year of 2001, we propose a new interpretative approach. Disregarding a wide view of the conception of conflict of interest, under Article 147, Paragraph 3, Item II, and the autonomously conception of interlocking board, under Item I, regardless the existence of any related conflict of interests, we propose a complementary view of items I and II, so that the disqualification of the board of directors applicant occurs when he/she holds of a position in a competing company and, as a result, have conflicting interests with the company. We also propose a new approach to the study of conflict of interests between managers and the company, suggesting a disconnection of the conclusions from the analysis of conflict of interests between shareholders and the company (Article 115, Paragraph 1) to accept the possibility of a prior analysis of the conflict of interests between managers and the company, even with the use of a substantial criteria.

Os estudos sobre escolha e preferência do comportamento individual a partir de esquemas concorrentes tornaram mais clara a função relativa do reforço no comportamento. No nível cultural, por sua vez, não há estudos experimentais sobre a função relativa de consequências culturais a partir de metacontingências concorrentes, o que certamente limita a compreensão do que leva um grupo a escolher/preferir engajar-se em uma prática em detrimento de outra. O presente trabalho teve o objetivo de aferir experimentalmente a frequência relativa de duas contingências comportamentais entrelaçadas (CCEs) como função da exigência de dois esquemas de razão concorrentes para produção de consequências culturais. Os esquemas de razão para cada contingência entrelaçada foram diferentes a depender da condição (conc FR1 FR1, FR1 FR2, FR1, FR3, FR2 FR2 e FR2 FR3). As duas contingências entrelaçadas relevantes para a produção de consequências culturais foram descritas na instrução, de modo a reduzir variações. Participaram do estudo 12 estudantes universitários divididos em quatro tríades. A tarefa experimental consistiu na escolha de linhas de uma matriz composta por dez linhas e dez colunas, sendo as linhas compostas por cinco cores diferentes alternadas, de modo que cada cor estivesse presente em uma linha par e outra ímpar. Consequências individuais (ganho de fichas trocáveis por dinheiro) foram contingentes a escolhas de linhas ímpares. Consequências culturais (itens escolares a serem doados a uma instituição) foram contingentes a sequências específicas de cores, que correspondiam às escolhas de linhas por cada um dos três participantes. Teve-se como resultados que as Tríades I e II tenderam à estereotipia da CCE associada ao esquema de menor razão ao final das condições, o que não ocorreu para as Tríades III e IV. Para as Tríades I e II, variações tenderam a ocorrer após mudanças de condições em que havia aumento da intermitência de consequências culturais associadas à CCE mais frequente. Também para as Tríades I e II, verbalizações sobre o procedimento foram mais frequentes nos períodos em que variações entre as CCEs relevantes foram mais frequentes. Para as Tríades III e IV, durante a maior parte do estudo não houve diferenciação da frequência entre as duas CCEs às quais consequências culturais eram contingentes, embora tenha havido diferenciação das duas CCEs em relação a outras / Studies about choice and preference using concurrent schedules contributed to better understand the relative function of the reinforcer on behavior. However, at the cultural level there are no experimental studies regarding the relative function of cultural consequences using concurrent metacontingencies, which certainly restricts the understanding about which variables lead a group to choose or prefer to engage in a practice over another. The objective of this experimental study was to assess the relative frequency of two interlocking behavior contingencies (IBCs) as a function of two fixed ratio schedules to produce cultural consequences. The ratio schedules to each interlocking contingency were different depending on the condition (conc FR1 FR1, FR1 FR2, FR1 FR3, FR2 FR2 and FR2 FR3). Both relevant interlocks for the production of cultural consequences were described in the instructions in order to reduce variability. 12 college students participated, divided into four triads. The experimental task consisted of row choices in a matrix comprising ten rows and ten columns, the rows being composed of five different colors, so that each color was present in an even and in an odd row. Individual consequences (earn of coins interchangeable for money) were contingent to the choice of odd rows. Cultural consequences (school supplies to be donated) were contingent to specific sequences of colors that corresponded to the combined row choices of the three participants. The results showed that Triads I and II leaned towards IBC stereotypy associated to the low ratio schedule at the end of the conditions, which did not occur for Triads III and IV. Triads I and II showed that variations tended to occur after experimental condition changes in which there were increased of the ratio schedule to cultural consequences associated to the more frequent IBC. Also, for Triads I and II, verbalizations about the procedure were more frequent when variations between the two IBCs were higher. For Triads III and IV, for most of the study there was no difference in frequency of the two relevant IBCs, although there was difference between the two relevant IBCs in relation to others

Other researchers in the behavior analysis interested in these studies, present in their studies (researches) the concept of metacontingency as a conceptual tool to the comprehension of cultural phenomenon. A number of attempts to produce analogous of metacontingency in an experimental environment have been made, and proceeding with these efforts the question which is the aim of the present study is whether the suspension of the consequences which are individually relevant, despite not having effects on the interlocking, would also have an effect on the selection of / by metacontingency. In other words, what would happen to the selected interlocking, if there was a suspension of contingencies to the operant behavior after the selection of / by metacontingencies? In order to do that, two experiments were designed. Experiment 1 was conducted by 3 (three) phases and the principal manipulation was removed from the individual consequence after the metacontingency was selected. The second experiment or Controlling Experiment, which did not include the selection phase and the strengthening of the operant behavior, in which only a determined relation between the participants and their consequent aggregated product were sequenced. The results indicated that in Experiment 1 there was not the simultaneous maintenance of the individual and cultural consequence. Nonetheless, it can be stated that both of them, at their own pace, showed to be under control of the programmed consequence. The Experiment 2 shows that independently of the selection of a specific operant behavior there was the selection of the IBCs and their aggregate product by cultural consequences. Results indicate that, despite of the operating selection being programmed, the aggregated product may emerge and the programmed cultural consequence may occur on the coordination as a way to strengthen it. Due to some circumstances which have arisen in Experiment 1, it is suggested that its replication with some modifications to determine the effects of the suspension of differential consequences of contingencies operating on IBCs / A inclusão dos fenômenos ditos culturais como objeto de interesse ou estudo da análise do comportamento tem inicio quando Skinner descreveu comportamento humano e aspectos característicos das relações sociais. Desse interesse participam outros estudiosos da análise do comportamento que em seus estudos tomaram o conceito de metacontingência como ferramenta conceitual para compreensão dos fenômenos culturais. Diversas tentativas de se produzir análogos de metacontingência em ambiente experimental tem sido feitas e dando continuidade a esses esforços a pergunta que dirigiu o presente estudo foi se a suspensão de conseqüências que são individualmente relevantes, mas que não são necessárias para a produção de produtos agregados, teria efeitos sobre os entrelaçamentos que envolvem a seleção de / por metacontingências. Ou seja, o que ocorreria com CCEs e seus produtos agregados, selecionados por conseqüências culturais, quando ocorre a suspensão de contingências para comportamentos operantes associadas (mas não necessárias) a tais produtos agregados? Para tanto foram delineados dois experimentos, o Experimento 1 foi constituído por 3 fases e a principal manipulação foi a retirada da conseqüência individual após selecionada uma metacontingência. No segundo experimento suprimiu-se a fase de seleção e fortalecimento do comportamento operante, nele somente uma determinada relação entre os participantes e seu conseqüente produto agregado eram consequenciados. Os resultados indicaram que no Experimento I não houve a manutenção simultânea da conseqüência individual e da cultural, embora seja possível afirmar que ambas as conseqüências programadas tiveram efeito selecionador. No Experimento 2 demonstrou-se que independente da seleção de um comportamento operante específico houve a seleção da contingências comportamentais entrelaçados e seu produto agregado por conseqüências culturais. Conclui-se que a despeito da seleção operante ser programada, o produto agregado pode emergir e a conseqüência cultural programada pode incidir sobre a coordenação de maneira a fortalecê-la. Devido a algumas circunstâncias que se apresentaram no Experimento 1, sugere-se sua replicação com algumas modificações para verificar-se os efeitos da suspensão de conseqüências diferenciais de contingências operantes sobre CCEs

Student Number : 0100677A - PhD thesis - School of Civil and Environmental Engineering - Faculty of Engineering and the Built Environment / This thesis presents the findings on empirical study of dry-stack masonry. Dry-stack masonry refers to a method of building masonry walls, where most of the masonry units are laid without mortar in the joints. Of late (since mid eighties) in modern construction, dry-stacking or mortarless technology is increasingly becoming popular because of its advantages. The construction industry is acknowledging the need to accelerate the masonry construction process, as the traditional method is labour intensive and hence slower due to the presence of a large number of mortar joints. Early attempts were made to increase the size of masonry units (block instead of brick), thereby reducing the number of mortar joints, wherein the use of bedding mortar imposed constraints on the number of courses to be constructed in a day. Elimination of bedding mortar accelerates construction; thereby reducing cost, variation due to workmanship and generally small pool of skilled labour is required in dry stacking. Dry-stack masonry is a relatively new technology not yet regulated in the code of practice and therefore very limited information on the structural behaviour of the masonry is available. This project is based on the investigation of the HYDRAFORM dry-stack system, which utilises compressed soil-cement interlocking, blocks. The system is now widely used in Africa, Asia and South America. The main objective of the project was to establish through physical testing the capacity of the system to resist lateral load (e.g. wind load), vertical load and dynamic load such as earthquake loading. In the first phase of the project investigations were conducted under static loading where series of full-scale wall panels were constructed in the laboratory and tested under lateral loading, and others were tested under vertical loading to establish the mode of failure and load capacity of the system. Series of control tests were also conducted by testing series of wallettes to establish failure mechanism of the units and to establish the flexural strength of the system. Finally the test results were used for modelling, where load prediction models for the system under vertical loading and under lateral loading were developed. The theoretical load prediction models were tested against the test results and show good agreement. After the load capacity was established the next step in the study was to further improve the system for increased capacity particularly under dynamic loading. The normal Hydraform system was modified by introducing a conduit, which allows introduction of reinforcements. Series of dry-stack seismic systems were constructed and initially tested under static lateral loading to establish the lateral load capacity. The second Phase of the project was to investigate the structural behaviour and performance of the Hydraform system under seismic loading. A shaking table of 20 tonnes payload, (4m x 4m) in plan was designed and fabricated. A full-scale plain dry-stack masonry house was constructed on the shaking table and subjected to seismic base motions. The shaking table test was performed using sine wave signals excitations starting from low to very severe intensity. A conventional masonry test structure of similar parameters was also constructed on the table and tested in a similar manner for comparison. The tests were conducted using a frequency range of 1Hz to 12Hz and the specimens were monitored for peak accelerations and displacements. For both specimens the initial base motion was 0.05g. The study established the mode of failure of the system; the structural weak points of unreinforced dry-stack masonry, the general structural response of the system under seismic condition and the failure load. The plain dry-stack masonry failed at 0.3g and the conventional masonry failed at 0.6g. Finally recommendations for further strengthening of system to improve its lateral capacity were proposed.

Interlocking compressed earth blocks (ICEBs) are cement stabilized soil blocks that allow for dry stacked construction. The incomplete understanding of the inelastic performance of ICEB building systems limits widespread acceptance of this structural system in earthquake prone areas. This thesis presents results from an experimental program designed to explore the behavior of ICEB walls, built according to current design practice in Indonesia and Thailand, and subjected to out-of-plane loading. A total of five reinforced and grouted ICEB walls were constructed and tested. Results from experimentation show the current masonry design code, ACI 530, adequately predicts the yield strength of these walls. However, ACI 530 grossly over-predicts the ICEB wall stiffness. All tests showed flexural behavior and failure, except for one wall. A brittle failure was observed in one wall before reaching the predicted flexural strength, prompting a suggested maximum shear tie spacing. The testing results provide useful data for developing analytical models that predicts the seismic behavior of ICEB walls under out-of-plane loading. A moment-curvature relationship was developed that accurately predicts the behavior of these walls in the elastic range as well as the inelastic range. By comparing the data provided by two walls of similar sizes, one including a pilaster and one without a pilaster, insight into stiffener elements was gained. Analysis of these two walls provides a limit on the length and height of ICEB walls without stiffener elements to prevent significant structural damage during a seismic event. In all, conclusions based on experimental data from ICEB out-of-plane loading tests are aimed to provide suggestions for ICEB construction in areas of high-seismicity.

This thesis investigates the flexural behavior of interlocking compressed earth block (ICEB) shear walls. In-plane cyclic tests were conducted to evaluate the performance of three flexure dominant large scale ICEB specimens: a slim wall with a 2:1 height to width aspect ratio, a flanged wall, and a wall with an opening at the center. Following the experimental investigation, two types of analyses were conducted for calculating the ultimate strength of flexure dominant ICEB walls: a nonlinear static analysis model assuming lumped plasticity and a plastic analysis model. In addition, incremental dynamic analysis was conducted to address the seismic performance of flexure dominant ICEB buildings. Based on the database from the incremental dynamic analysis, the collapse potential of demonstration ICEB buildings were compared for the countries of interest.

Using advanced composites, an emergency shelter system has been designed. The system parameters are hurricane resistance to 138 mph wind velocity, simple erection, light weight, high durability and rapid construction. The project involves the solicitation of design proposals from several building system manufacturers and the development of an optimized emergency shelter system. The usage is well suited to pultruded members made from fiber reinforced polymers (FRP). Due to the anisotropic nature of FRP composites, a limited amount of research has been conducted to develop design optimization techniques for panels used in construction. This project allows for the development of optimization techniques for use in pultruded FRP panel members. The Project consisted of a detailed literature review conducted of emergency building industry to assess the validity of existing shelter systems, a state of the art review of connection design in FRP structures with an emphasis on non-standard types of connectors (ie...snap type), systemic structural optimization of emergency shelter for building geometry, roof configuration, foundation anchorage and building envelope, development of statistical methods for evaluation of viable existing emergency shelter systems. Subsequent to the initial phase of the investigation, an interlocking FRP composite panel system was developed. The system was analyzed for local buckling, first ply failure and global deflection criteria using modified equations originally developed for open section members. The results were verified using Finite Element Methods analysis software. The findings from the study indicate the need for a second phase in which the most promising available systems and the concept developed are fully tested to verify their capacity to withstand high wind forces including impact of wind borne debris.

The design project presented here explores the relation between body and a garment. It is concerned simultaneously with the fundamental notion of a garment and the act of dressing. The project can be contextualized as a constructive design research since the aim does not involve analysis of the material world nor rational problem solving. Rather, the aim is to create new imaginary realities, and visualize them. As a startup method to construct a theory, workshops were set up using life size vertical action collages, in order to integrate the act of dressing with the aim to develop a new construction method. Two actors, one of them myself, were used to provide a greater diversity of perspectives and interpretations. A method of dressing which involved interlocking the body - limbs and waist - with vertically hanging textiles, was developed through the search for the holes, that constitute the infrastructure of a garment. The results are both artefacts, that visualize the new garment construction as well as a new routine of dressing through the novel method of garment construction. Dressing a body in textiles through interlocking which results in an intimate connection between body and the garment as the body reacts to the garment and vice versa. The motivation for exploring the act of dressing is an urge to reflect upon the fast evolving society of today which tends to emphasize a static relationship between body and a garment.
