Abstract:
While 3D digital design tools have extended the reach of architectural and engineering designers within their own domains, restrictions on the use of the tools and an approach to practice whereby the architect designs (synthesises) and the engineer solves (analyses) - in that order ¡V have limited the opportunities for interdependent modes of interaction between the two disciplines during the early design phase. While it is suggested that 3D digital design tools can facilitate a more integrated approach to design exploration, this idea remains largely untested in practice. The central proposition of my research is that that 3D digital tools can enable interdependencies between crucial aspects of architectural and engineering design exploration during the early design phase which, before the entry of the computer, were otherwise impossible to affect. I define interdependency as a productive form of practice enabled by mutual and lateral dependence. Interdependent parties use problem solving processes that meet not only their own respective goals, but also those of others, by constructively engaging difference across their boundaries to actively search for solutions that go beyond the limits of singular domains. Developed through practice-based project work undertaken during my 3 year postgraduate internship within the Melbourne Australia office of the engineering firm Arup, my research explores new and improved linkages between early design exploration, analysis and making. The principal contribution of my research is to explore this problem from within the context, conditi ons and pressures of live practice. To test the research proposition this dissertation engages firstly with available literature from the fields of organisation theory and design, secondly with information gathered from experts in the field principally via interview, and lastly with processes of testing through practice-based (as opposed to university-based) project work. The dissertation is organized as follows: The Introductory Chapter outlines the central hypothesis, the current state of the discourse, and my motivations for conducting this research. I summarise the structure of my research, and the opportunities and limitations that have framed its ambitions. Chapter Two, Approach to Research and Method, details the constraints and possibilities of the Embedded Research within Architectural Practice context, within which this work has been undertaken, and describes the Melbourne office of Arup, the practice with whom I have been embedded. These contexts have led to the selection of a particular set of ethnographic research instruments, being the use of semi-structured interviews and the undertaking of practice-based studies as a participant-observer. These modes of testing are explained, and the constraints, limitations and requirements associated with them described. Within Chapter Three, Factors for Separation and Integration in Architectural and Engineering Design, I examine selected design literature to detail several factors impacting upon the historic and contemporary relationship between architects and engineers, and to introduce the problem towards which this thesis is addressed. I describe a process of specialisation that has led architects and engineers to see different aspects of a common problem, detail the historical factors for separation, the current relationship between domains and the emerging idea of increased integration during the early design phase. The aim of this section is primarily contextual - to introduce the characters and to understand why their interaction can be difficult - and investigation occurs through the concepts of specialisation and disciplinary roles. Chapter Four, Unravelling Interdependency, establishes an understanding of interdependency through the concept of collaboration. While I differentiate interdependency from collaboration because of the inconsistent manner in which the latter term is employed, the concept of collaboration is useful to initialise my understanding of interdependency because it, as opposed to the closely linked processes of cooperation and coordination, is recognised as being characterised by interdependency, and in fact is a viewed as a response specific to wider conditions of interdependency. From the literature, I identify four sites of intersection crucial to an understanding of interdependency; these are differing perceptions, shared and creative problem solving, communication and trust. These themes, which correlate with my practice experience at Arup Melbourne, are developed to introduce the concepts and vocabulary underlying my research. Chapter Five, Intersections & Interdependency between Architects and Engineers, grounds these four sites of intersection within contemporary issues of digital architectural and engineering practice. Each site is developed firstly through reference to design literature and secondly through the experiences and understandings of senior Arup practitioners as captured through my interviews. The views and experiences of these practitioners are used to locate digital limits to, and potential solutions for, interdependent design exploration between architects and engineers as they are experienced within and by practice. Through this combination of design literature and grounded experience, I extend: * the understanding of differing perceptions through reference to problems associated with digital information transfer. * the understanding of joint and creative problem solving by connecting it to the notion of performance-based design. * the understanding of communication by focussing it upon the idea of back propagating design information. * the understanding of trust by connecting it to the management and reduction of perceived complexity and risk. Chapter Six, Testing through Projects, details the project studies undertaken within this research. These studies are grouped into three discourses, characterized as Design(Arch)Design(Eng), Design|Analysis and Design|Making. As suggested by the concurrency operator that separates the two terms that constitute each of the three labels, each discourse tests how architectural and engineering explorations might execute in parallel. The section Design(Arch)|Design(Eng) reports projects that use a common language of geometry to link architectural and engineering design ideas through geometric interpretation. The section Design|Analysis reports projects in which analytical tools have been used generatively to actively guide and synthesise design exploration. The final section, Design|Making, reports projects in which the architectural and engineering design processes are synthesised around the procurement of fabrication information. Conclusions are then drawn and discussed in Chapter Seven. In evaluating the research I discuss how 3D digital design tools have enabled alternative approaches that resolve issues associated with differing perceptions, establishing common meanings, communication and trust. I summarise how these approaches have enabled increased interdependency in architect engineer interaction. Lastly, I draw together the impacts of intersecting 3D digital aspects of architectural and engineering design exploration during the early design phase, and indicate those aspects that require further analysis and research.

Abstract:

In the U.S. medical sector, software failures in safety-critical systems in healthcare have led to serious adverse health problems, including patient deaths and recalls of medical systems. Despite the efforts in developing techniques to build resilient systems, there is a lack of consensus regarding the definition of resilience metrics and a limited number of quantitative analysis approaches. In addition, there is insufficient guidance on evaluating resilience design patterns and the value they can bring to safety-critical systems.

This research employed the interdependency analysis framework to evaluate the static resilience of safety-critical systems used in the healthcare field and identified software subsystems that are vulnerable to failures. Resilience design patterns were first implemented to these subsystems to improve their ability to withstand failures. This implementation was followed by an evaluation to determine the overall impacts on system’s static resilience.

The methodology used a common medical system structure that collects common attributes from various medical devices and reflects major functionalities offered by multiple medical systems. Fault tree analysis and Bayesian analysis were used to evaluate the static resilience aspects of medical safety-critical systems, and two design patterns were evaluated within the praxis context: Monitoring and N-modular redundancy resilience patterns.

The results ultimately showed that resilience design patterns improve the static resilience of safety-critical systems significantly. While this research suggests the importance of resilience design patterns, this study was limited to explore the impact of structural resilience patterns on static resilience. Thus, to evaluate the overall resilience of the system, more research is needed to evaluate dynamic resilience in addition to studying the impact of different types of resilience design patterns.

Abstract:
The fundamental advancement of information technology has given rise to distance education industry hence it has helped to the popularity of distance education among people. However, for employing innovative and advanced tools universities need financial resources. Reaching to these resources is not easy and accessible. Interaction equivalency theorem can be a good solution for overcoming the financial problems but designers are reluctant to utilize it because they think that education quality will decrease due to lack of teacher interaction. This study demonstrated that students’ perception toward interaction equivalency is positive as long as they have high level of interdependency with other students. Without this level of, students are not motivated in order to continue their courses. This study by providing techno-pedagogical design and IS design theory for support of IE helps e-learning practitioners who want to design an acceptable distance educational system with limited financial resources.

Abstract:
Dans un contexte international marqué par la prise de conscience des enjeux environnementaux, et dans un contexte national d'injonctions réglementaires visant la réduction de la consommation énergétique, les disciplines liées à l’aménagement de l’espace voient leurs frontières et leurs méthodes évoluer de manière conséquente. Cette thèse a pour objet d’analyser les influences du développement durable sur le processus de création en architecture dans le cadre particulier du Global Award for Sustainable Architecture™ et en fonction de la réglementation sur le bâtiment et le territoire en France. Elle examine des mutations des modes opératoires du processus du projet architectural et propose des éléments de méthode et d'analyse concernant la prise en compte des piliers du développement durable, l'environnement, l'économie, la société et la culture. Il ressort de l’analyse que la compréhension des enjeux du développement durable rassemble dans une même dynamique intégrative les différentes piliers, faisant ainsi de la complexité la condition pour leur interdépendance. La prise en compte de la complexité à travers le milieu qui est attestée par les cas étudiés dans cette thèse soulève des questions sur le déroulement du processus du projet à travers une imagination pluraliste qui dépasse une réponse universelle normalisée. Si la complexité se traduit par la prise en compte simultanée des dimensions urbaines et rurales, paysagères et architecturales, quantitatives et qualitatives, elle envisage également le croisement et l’interdépendance des métiers. Ce qui signifie que l’architecte doit -en tant que médiateur- (se) construire une nouvelle identité, développant des compétences en conduite de conception et de négociation
Global awareness of environmental matters and local regulations intending reductions of energy consumption forces disciplines related to space to expand their working methods in a substantial way. This thesis analyses influences of sustainable development on the architectural design process, particularly the case of the Global Award for Sustainable Architecture™ and the case of the French context in accordance to the regulation of building and territorial matters in France. It examines the mutations of the modus operandi of the process and offers elements of method and analysis towards the consideration of Pillars of sustainable development , environment, economy, society and culture. The analysis shows that the understanding of the sustainable development issues gathers the different Pillars in common integrative dynamics, making "Complexity" the condition of their interdependency. The account of the "Complexity" through milieu as attested by the case studies in this thesis, raise questions on the project's process through a pluralist imagination that goes beyond a normalised universal answer. When "Complexity" is being applied with a simultaneous consideration of urban, rural, landscaped, architectural, quantitative and qualitative dimensions, it heads towards the crossing and the interdependency of professions. This means that architects as mediators have to build themselves a new identity, cultivating proficiency and competency in leading conception and negotiation of the architectural project

Full text
Abstract:
The research looks at the design of fiscal and monetary policy in EMU. The characteristics of the "economic constitution" established in the Maastricht treaty are analysed to test their robustness to different hypothesis about fiscal sustainability and fiscal and monetary policy interaction. Chapter two illustrates how the possibility of default of public debt in one large member country creates interdependence among fiscal positions of all member countries. Chapter three and four show that a similar kind of interdependence between national fiscal position could be determined by the effect that un-funded fiscal expansions have on the level of prices. The theoretical argument, borrowed from the so called Fiscal Theory of Price Determination, is developed both in a closed economy, to illustrate the basic mechanism and its interpretation, and in a two country monetary union model. Chapter five analyses, in a game theoretical framework, how the interdependence between policy instruments should be recognised in full, in order for any policy to be effective. In a situation in which a possible conflict of objectives or preferences between policy makers is present, any institutional arrangements which does not deal with it positively is intrinsically inefficient and can result in the policies cancelling each other out. The last chapter develops an example on how the conflict between policy institutions can be endogenous to an institutional structure chosen to reduce the influence of policy uncertainty on the economy. It is therefore a note of caution about the common belief that is possible with simple institutional solutions to overcome differences in preferences or objectives that are characteristic of the European environment. The analysis suggests that both greater fiscal policies cooperation and decentralisation of policy institutions from national to regional are developments necessary to achieve the policy goals of the Monetary Union.

Full text
Abstract:
The current study sought to add to the literature on applying interdependent group-oriented contingency systems with randomized components to academic performance. This study expanded previous work, which has only examined effects on elementary classrooms and students with disabilities, by implementing a similar intervention within a general education, secondary classroom. Given the restricted time that teachers have to learn and implement interventions, while simultaneously carrying out all their additional responsibilities in the classroom, it is necessary for school psychologists to consider these limitations when recommending interventions. In previous work involving interdependent group-oriented contingencies, the delivery of reinforcement has been relatively immediate. While this is an ideal arrangement, it may be infeasible for middle and high school teachers to ensure reinforcement of academic performance occurs immediately within the class period. This study examined whether the delivery of reinforcement can be delayed within an interdependent group-oriented contingency system and still improve the academic performance of students in the classroom, which will allow the teacher more time for evaluating the quality of student work and, in turn, impact the acceptability of the intervention. One middle school, general education classroom served as the setting for this study. Academic performance data, including in-class work completion and accuracy rates, were collected class-wide and data on social behavior variables were gathered for 3 students exhibiting moderate to high levels of off-task behavior, based on teacher perception. An alternating treatments design was employed with two intervention conditions: one condition included immediate reinforcement and the other involved delivering reinforcement to students a day later. The interdependent group-oriented contingency intervention implemented included procedures for randomly selecting target behaviors, criteria, and reinforcers.

Includes bibliographical references (p. 247-255).
This research developed a methodology to assess the design of complex large-scale products with respect to the performance of their production processes. In complex large-scale projects, physical and functional relationships among the product systems and components, along with concurrency and co-location of their production processes, generate inter-system process dependencies that drive the relative production rates among the systems. The methodology links the complexity of the product to the complexity of the production process at the level of detail of the single component and task to model the impacts of inter-system process dependencies on production performance. This detailed focus makes the methodology highly responsive to changes in design and technology and able to capture primary, secondary and tertiary impacts of change on production performance. Based on the methodology, a dynamic process simulation model has been developed to systematically assess different combinations of design and technology alternatives across multiple dimensions of production performance. Performance measures include project duration, costs, resource utilization and index of workers' exposure to dangerous conditions. Simulated scenario testing based on actual data from a construction project, the renovation of Baker House (MIT building W7), demonstrates that 1) inter-system process dependencies strongly influence production performance, 2) these links build their dynamic effects on production performance at the detailed task and component level, and 3) the nature of the links and their spatial and temporal location vary as changes are introduced in the design and in the production specifications. One important consequence is that the specification and optimization of the production processes for product systems and components as separate from one another leads to solutions that may be sub-optimal for the performance of the whole project. In addition, the specification and the representation of complex production processes at the aggregate level fails to capture important impacts of design and technology changes and, thus, leads to inconsistent duration and cost estimates.

Abstract:
Pornography has increasingly become a hot topic of discussion in the United States, likely due to its increasing rate of consumption. Recent scholarship has indicated the need to account for factors such as masturbation and sexual desire discrepancy when conducting pornography research. The current study isolated the influence pornography use had on those in heterosexual romantic relationships (N=713 couples) by parsing out the effects of sexual desire discrepancy and masturbation. This was done by using a series of nested actor-partner interdependence models (APIM) to see how the relationships between pornography use and sexual satisfaction changed in each model. Masturbation and sexual desire discrepancy were also investigated as potential moderators for the APIMs to explore the effects the levels of these variables had on that relationship. Results from these analyses demonstrated that the best-fitting model included measures of masturbation, sexual desire discrepancy, and sexual engagement (i.e., controls for the values making up sexual desire discrepancy), and that adding each of these variables to the model significantly changed pornography use's actor and partner effects. Masturbation and sexual desire discrepancy were not found to moderate these relationships. A discussion of the research implications of these findings, the limitations of this study, future directions for research, and clinical implications of this study are also presented.

Abstract:
Driven by the demands of drastic changes in today’s nature of work due to globalization and technological advances, researchers have continually revisited, redesigned, and restructured work design processes in a quest to identify the key characteristics that can result in desired organizational outcomes. Specifically, in current times, organizations are looking to develop socially responsible outcomes, otherwise referred as corporate social responsibility (CSR). A possible link between work design and CSR has been postulated by researchers, but few studies have emerged where the associations between work design and CSR factors are examined. The purpose of this study was to explore the link between work design and CSR using a work design-CSR conceptual model that was developed based on previous literature. The model depicted relationships between work design factors and CSR factors. Work design factors included work characteristics and worker characteristics. Work characteristics were measured using task, knowledge, social, and contextual characteristics; while worker characteristics were measured using personality traits. CSR Orientation (CSRO) was used as a reflective indicator of CSR at the individual level. The study sample consisted of 941 job incumbents of a public education institution in Texas. The data were collected using an online survey that included the work design questionnaire, the short Big Five Inventory, and the CSRO questionnaire. The model was tested using Structural Equation Modeling. Based on the results, a significant association between work characteristics and CSRO factors were obtained. As hypothesized, associations were found between task characteristics and profit CSRO, and between social characteristics and legal CSRO and philanthropic CSRO. The knowledge characteristics were found to have negative association to philanthropic CSRO. The findings also suggest that jobs that are high on problem solving and job autonomy had a negative association to philanthropic CSRO. Similarly, as the job complexity increased, individuals’ orientation towards profit making decreased, and information processing was found to be linked to legal compliance. Research and practice implications of these results are discussed.

This study is to present an intelligent collaborative service system (CSS) design (iDesign) including the CSS classification, an analysis-design modeling method, and an experience quality evaluation model for systematic service innovation. State-of-the-art information technology can be used to develop the CSS according to three comprehensive procedures, enabling semi-automated value co-production and systematic service innovation that can meet the goals of service productivity and customer satisfaction for service providers and customers. In view of the preceding research purpose, the three major research questions are addressed in this study: What kind of collaborative service systems can be classified and identified based upon the prerequisites of value co-production? How the collaborative service systems can be modeling and automating its cognitive process and knowledge representations using an analysis-design method (i.e. intelligent service machine)? How an evaluation model can measure the experience quality of the service providers and the customers, and embed the model into the CSS in order to perform service quality management? Meanwhile, the evidences to effects of iDesign-based CSS applications that implemented by the three practical service systems of artwork design, for example, a transactional marketplace service system for mediating music content creation (DesignStorming), a collaborative alignment service system for assisting mobile phone design service (iMobileDesign), and a collaborative personalization service system for facilitating interior design service (iInteriorDesign). According to the research process of design science, this study adopts a single case study to refine the proposed artifact (i.e., iDesign). iInteriorDesign is one of iDesign-based CSS applications, which is analyzed and developed by simple service machine (SSM) and intelligent service machine (ISM) and with the embedded evaluation of E-QUAL based upon one category of classification framework of iDesign. This qualitative study draws the deductive consequence and further proposed a deductive model of theory a (Symbiotic Collaborative Service Model) built by means of the resource dependence theory (RDT) testing. iInteriorDesign envisions an entirely new interior design service experience enabling collaborative interior design provision; architects or interior designers can use the system to effectively communicate with customers based upon symbiotic interdependence relationship behavior to better identify their needs and wants and even attain new inspirations of concept styles from the interactions. The results of case study have conducted the deductive important behavior of symbiotic interdependence relationship within the CSS applications. The results of qualitative research also can further generalize the identical behavior to the adaptability and evolution of value co-production and mutual adaptability within iDesign.

Satyanath, Bhat K. "Design of Quality Assuring Mechanisms with Learning for Strategic Crowds." Thesis, 2017. http://etd.iisc.ernet.in/2005/3597.

Full text
Abstract:
In this thesis, we address several generic problems concerned with procurement of tasks from a crowd that consists of strategic workers with uncertainty in their qualities. These problems assume importance as the quality of services in a service marketplace is known to degrade when there is (unchecked) information asymmetry pertaining to quality. Moreover, crowdsourcing is increasingly being used for a wide variety of tasks these days since it offers high levels of flexibility to workers as well as employers. We seek to address the issue of quality uncertainty in crowdsourcing through mechanism design and machine learning. As the interactions in web-based crowdsourcing platform are logged, the data captured could be used to learn unknown parameters such as qualities of individual crowd workers. Further, many of these platforms invite bids by crowd workers for available tasks but the strategic workers may not bid truthfully. This warrants the use of mechanism design to induce truthful bidding. There ensues a complex interplay between machine learning and mechanism design, leading to interesting technical challenges. We resolve some generic challenges in the context of the following problems. Design of a quality eliciting mechanism with interdependent values We consider an expert sourcing problem, where a planner seeks opinions from a pool of experts. Execution of the task at an assured quality level in a cost effective manner turns out to be a mechanism design problem when the individual qualities are private information of the experts. Also, the task execution problem involves interdependent values, where truthfulness and efficiency cannot be achieved in an unrestricted setting due to an impossibility result. We propose a novel mechanism that exploits the special structure of the problem and guarantees allocative efficiency, ex-post incentive compatibility and strict budget balance for the mechanism, and ex-post individual rationality for the experts. Design of an optimal dimensional crowdsourcing auction We study the problem faced by an auctioneer who gains stochastic rewards by procuring multiple units of a service from a pool of heterogeneous strategic workers. The reward obtained depends on the inherent quality of the worker; the worker’s quality is fixed but unknown. The costs and capacities are private information of the workers. The auctioneer is required to elicit costs and capacities (making the mechanism design dimensional) and further, has to learn the qualities of the workers as well, to enable utility maximization. To solve this problem, we design a dimensional multi-armed bandit auction that maximizes the expected utility of the auctioneer subject to incentive compatibility and individual rationality while simultaneously learning the unknown qualities of the agents. Design of a multi-parameter learning mechanism for crowdsourcing We investigate the problem of allocating divisible jobs, arriving online, to workers in a crowd-sourcing platform. Each job is split into a certain number of tasks that are then allocated to workers. These tasks have to meet several constraints that depend on the worker performance. The performance of each worker in turn is characterized by several intrinsic stochastic parameters. In particular, we study a problem where each arriving job has to be completed within a deadline and each task has to be completed, honouring a lower bound on quality. The job completion time and quality of each worker are stochastic with fixed but unknown means. We propose a learning mechanism to elicit the costs truthfully while simultaneously learning the stochastic parameters. Our proposed mechanism is dominant strategy incentive compatible and ex-post individually rational with asymptotically optimal regret performance.

Abstract:
Love and sex change over the course of a relationship. The current research investigates the factors that contribute to sexual desire and sexual satisfaction in long-term couples. In two studies, the association between motivational goals for sex, interdependence, and sexual outcomes were explored. Study 1 was a cross-sectional survey. The results of Study 1 revealed that participants who engaged in sex more often for approach goals reported higher levels of desire, whereas participants who engaged in sex more often for avoidance goals reported lower levels of desire. Study 2 was a 21-day daily experience study involving a subset of the participants from Study 1. The results of Study 2 indicated that on days when participants reported engaging in sex more for approach goals they reported greater sexual desire, whereas on days when participants reported engaging in sex more for avoidance goals they reported lower levels of sexual desire. Partner-focused, as opposed to self-focused sexual goals, were primarily responsible for these associations. In both studies, relationship satisfaction was also associated with higher desire, and this was mediated by the tendency of people who are more satisfied to engage in sex more often for approach goals. In Study 2, approach goals moderated the impact of avoidance goals on sexual desire, and this association differed by gender. Stronger approach goals buffered against declines in sexual desire associated with avoidance goals for women, but not for men. The findings support the utility of applying a motivational framework to the study of sexuality in established couples and the greater relevance of partner-focused sexual goals in long-term relationships.

Abstract:
The purpose of the study was to develop a wellness model for teachers in addressing learning barriers for learners with hearing impairment. The study is underpinned by three theories, namely, the Linguistic Interdependence Theory, the Universal Design for Learning and the Wellness Theory to generate understanding of how learners with hearing impairment learn. Ethical standards were adhered to in terms of gaining permission for access, issues of informed consent, voluntary participation, and confidentiality. The study is premised on the pragmatism philosophy that favours a mixed method approach, using both qualitative and quantitative methods of data collection and analysis and interpretation of data. The mixed method is a multi-method, ensuring multiple angles in data collection, interpretation and analysis. Data collection and analysis were concurrent because data were collected and analysed as soon as the data were available. The study used a purposive sampling approach to select samples of educators who responded to the questionnaires and those who participated in the interviews. Three provinces and 11 schools were purposively selected because of their history of providing quality education to learners with hearing impairment. The researcher knew all the schools. One hundred deaf educators (86 female and 14 male) participated in answering a semi-structured, self-completion questionnaire. All respondents were school-based teachers of the deaf, teaching Grade R to seven. Eleven primary school educators were interviewed, consisting of eight women and three men. Concurrent data analysis was used to compare quantitative and qualitative data, which revealed that learners faced several wellness challenges. Most of the learners faced literacy challenges in reading, communication with the hearing and limited academic, social and career dimensions. Some positive strides were showing in the physical and spiritual wellness through health promotion and moral education. The study proposed an integrated wellness model integrating the three lenses. The following four themes emerged from the study. The first theme is that academic challenges are major barriers faced by learners with hearing impairments. The second theme noted that deaf learners faced communication challenges. The third theme indicated curriculum, adaptation, and multidisciplinary teams as factor where hearing-impaired needed support to address barriers to learning. The last theme called for more programmes to be introduced to address academic, career, and spiritual wellness.
