This thesis presents a study of the role of western lamas within Tibetan Buddhism in America, arguing that the role of the lama is as an influential and central aspect in the development and transformation of the Tibetan Buddhist tradition in the west. This thesis argues how western lamas holding a position of authority act as a catalyst of change within their group and in the overall process of change and adaptation of the Tibetan Buddhist tradition in America, creating what may become ‘American Tibetan Buddhism.’ Three relevant areas regarding the role of the lama within the transforming tradition are identified: 1) the basis of authority of the lama, or how authority is obtained; 2) the use of such authority as a tool for change; and 3) transmission of the teachings and lineage.

This dissertation examined the formation of Japanese identity politics after World War II. Since World War II, Japan has had to deal with a contradictory image of its national self. On the one hand, as a nation responsible for colonizing fellow Asian countries in the 1930s and 1940s, Japan has struggled with an image/identity as a regional aggressor. On the other hand, having faced the harsh realities of defeat after the war, Japan has seen itself depicted as a victim. By employing the technique of discourse analysis as a way to study identity formation through official foreign policy documents and news media narratives, this study reconceptualized Japanese foreign policy as a set of discursive practices that attempt to produce renewed images of Japan’s national self. The dissertation employed case studies to analyze two key sites of Japanese postwar identity formation: (1) the case of Okinawa, an island/territory integral to postwar relations between Japan and the United States and marked by a series of US military rapes of native Okinawan girls; and (2) the case of comfort women in Japan and East Asia, which has led to Japan being blamed for its wartime sexual enslavement of Asian women. These case studies found that it was through coping with the haunting ghost of its wartime past that Japan sought to produce “postwar Japan” as an identity distinct from “wartime imperial Japan” or from “defeated, emasculated Japan” and, thus, hoped to emerge as a “reborn” moral and pacifist nation. The research showed that Japan struggled to invent a new self in a way that mobilized gendered dichotomies and, furthermore, created “others” who were not just spatially located (the United States, Asian neighboring nations) but also temporally marked (“old Japan”). The dissertation concluded that Japanese foreign policy is an ongoing struggle to define the Japanese national self vis-à-vis both spatial and historical “others,” and that, consequently, postwar Japan has always been haunted by its past self, no matter how much Japan’s foreign policy discourses were trying to make this past self into a distant or forgotten other.

This article is the first linguistic analysis of a new category of lifestyle magazines in the German speaking countries, based on methods of corpus linguistics and multimodal discourse analysis. Since the launch of the magazine LandLust in Germany in 2005, more than twenty publications of so called "land magazines" have appeared on the market, attracting millions of readers. Our research analyses land magazines as discursive events. We examine the specific combination of discourses land magazines are serving or creating by looking at the semiotic practices – writing and images – they manifest themselves by. Our results show that the magazine under scrutiny does not simply provide new forms of escapism but also positions itself politically in subtle ways as part of the traditional-conservative spectrum by reacting to metalinguistic discourses such as purism and feminist criticism.

This study aims to explore the construction of difference in foreign news discourse on culturally similar but politically different non-Western subjects. Applying critical discourse analysis (CDA) together with a critique of Eurocentrism, the study examines difference in newspaper constructions of government supporters and oppositional groups in Venezuela. Discursive differences are evident in the strategies used for constructing the two groups with regard to political rationality and violence. Government supporters are associated with social justice, Venezuela’s poor, dogmatic behavior, and the use of political violence. The opposition, in contrast, is constructed as following a Western democratic rationale that stresses anti-authoritarianism. This group is primarily associated with victims of violence. While the opposition is conveyed as being compatible with Eurocentric values and practices, government supporters to great extent deviate from these norms. Such constructions serve to legitimize politico-ideological undercurrents of Eurocentrism, as the defense of liberalism.

This article collects the main ideas constructed during a research process that allowed an approach to the study of the construction of school identities. The approach undertaken starts off not only from an analysis of the way in which the identities that converge in the dynamics of an educational institution and their relationship with the national educational proposal are constructed and articulated, but also the identification, starting from that analysis, of some possible lines of action on the formation of education professionals.

Contractual relationships have become increasingly strained in recent years in the construction industry result in the use of the judicial system for the settlement of contractual disagreements. Why is this so? Evidence from anecdotes suggest that the lack of capacity amongst owners and contractors to carry out a contract using a good practice approach during the construction of a project contribute to the occurrence of conflicts, losses, deficient contractual relationships and poor performance of the construction work. Recognizing that current forms of contract in use today perpetuate a legacy of construction problems, we are conducting explanatory research to examine whether the widely publicized benefits of New Engineering Contract (NEC) could be realized in the Australian construction industry. This paper outlines a research agenda that will help shed light on how contract forms are able to be used as a mechanism to ensure construction projects are delivered successfully whilst also meeting the goals of multiple stakeholders. Understanding the Critical Success Factors (CSFs), commonly used construction contracts and the NEC system can help us address some of these issues. However, there are gaps in the validation of the benefits of NEC and its link with project success. We identify some of these gaps and propose a methodology by which to gain insights into this phenomenon. Keywords: Project Success, Construction Contracting, New Engineering Contract (NEC)

The paradoxical co-existence of conflicting logics governs practices in cultural organizations. This requires ‘balancing acts’ between artistic and managerial efforts, which are often subjects to struggle among the organizational members. This ethnographic study aims to go beyond either-or thinking on the paradoxical organizational context by examining how the organizational members of an opera house construct views on their organization in dialogical meaning-making processes. Various professional groups, dozens of upcoming productions, increased international cooperation, and global competition combined with scarce financial resources make opera houses a complex though interesting context for organization studies. In order to provide a deeper knowledge of the internal dynamics of an opera organization this thesis takes an interpretative view to examine the ways organizational members construct and make sense of their organization. How is the opera organization constructed by the organizational members? How do the members draw on different logics when relating to their organization? Or what are the elements that characterize the relational processes of organizational identity construction in an opera organization? The thesis aims to answer these questions by providing a detailed description of the everyday life of an opera organization and a particular focus put on organizational identity construction. The processes of organizational identity construction are approached from a relational point of view. This may involve various relations between multiple positions, different professional groups, other organizations in the cultural field or between past and present understandings of an organization. The study shows that the construction of an opera organization involves not only the two conflicting logics of art and economy, but also the logic of a national institution. The study suggests also that organizational identities are constructed through processes related to the dialogics of positions, work and management practices. The dialogics involve various struggles through which the organizational members find themselves between the different organizational aspects such as visiting ‘stars’ and an ensemble or between ‘Finnishness’ of opera productions and internationalization. In addition, the study argues that a struggle between different elements is a general mode of relation in cultural organizations and therefore an inherent and enduring aspect in the organizational identity construction. However, the space of ‘being in between’ involves both the enabling and constraining elements in the dialogical identity construction in the context of cultural organizations, which present the struggle in a more generative light.

In this paper, we consider the security of exact-repair regenerating codes operating at the minimum-storage-regenerating (MSR) point. The security requirement (introduced in Shah et. al.) is that no information about the stored data file must be leaked in the presence of an eavesdropper who has access to the contents of l(1) nodes as well as all the repair traffic entering a second disjoint set of l(2) nodes. We derive an upper bound on the size of a data file that can be securely stored that holds whenever l(2) <= d - k +1. This upper bound proves the optimality of the product-matrix-based construction of secure MSR regenerating codes by Shah et. al.

This paper presents the construction, mathematical modeling and testing of a scaled universal hydraulic Power Take-Off (PTO) device for Wave Energy Converters (WECs). A specific prototype and test bench were designed and built to carry out the tests. The results obtained from these tests were used to adjust an in-house mathematical model. The PTO was initially designed to be coupled to a scaled wave energy capture device with a low speed and high torque oscillating motion and high power fluctuations. Any Energy Capture Device (ECD) that fulfils these requirements can be coupled to this PTO, provided that its scale is adequately defined depending on the rated power of the full scale prototype. The initial calibration included estimation of the pressure drops in the different components, the pressurization time of the oil inside the hydraulic cylinders and the volumetric efficiency of the complete circuit. Since the overall efficiency measured during the tests ranged from 0.69 to 0.8 and the dynamic performance of the PTO was satisfactory, the results are really promising and it is believed that this solution might prove effective in real devices.

The article analyses the construction process, the evolution and the disturbing future of the facade enclosure of the collective housing constructions built during the developmental period in the province of Gipuzkoa. 128 residential complexes were checked, and 17 people who directly took part in the construction of many of these buildings were interviewed. After examining the material and elements that make up the conventional facade solution used in Gipuzkoa and in much of Spain not only during those years but also up to the present time, the effects and causes of its main damages and flaws were studied. Its complex and costly adaptation to current demands is going to require a strong effort from society at large, and this raises the question of whether the life cycle of this construction system should be terminated once and for all.

Following the commencement of construction works of a 250 MW hydropower plant at Dumbbell Island in the Upper Victoria Nile in September 2007, BEL requested NaFIRRI to conduct continuous monitoring of fish catches at two transects i.e. the immediate upstream transect of the project site (Kalange-Makwanzi) and the immediate downstream .transect (Buyala-Kikubamutwe). The routine monitoring surveys were designed to be conducted twice a week at each of the tWo transects. It was anticipated that major immediate impacts were to occur during construction, and these needed to be known by BEL as part of a mitigation strategy. For example, the construction of it cofferdam could be accompanied by rapid changes in water quality and quantity downstream of the construction. These changes in turn could affect the fish catch and would probably be missed by the quarterly monitoring already in place. Therefore, a major cbjective of the more regular and rapid monitoring was to discern immediate impacts of construction activities by focusing on selected water quality parameters (total suspended solids, water conductivity, temperature, dissolved oxygen and pH) and fish catch characteristics (total catch, catch rates and value of the catch)

Purpose - The aim of this study was to investigate whether the presence of a whole-face context during facial composite production facilitates construction of facial composite images. Design/Methodology - In Experiment 1, constructors viewed a celebrity face and then developed a facial composite using PRO-fit in one of two conditions: either the full-face was visible while facial features were selected, or only the feature currently being selected was visible. The composites were named by different participants. We then replicated the study using a more forensically-valid procedure: In Experiment 2 non-football fans viewed an image of a premiership footballer and 24 hours later constructed a composite of the face with a trained software operator. The resulting composites were named by football fans. Findings - In both studies we found that presence of the facial context promoted more identifiable facial composite images. Research limitations/implications – Though this study uses current software in an unconventional way, this was necessary to avoid error arising from between-system differences. Practical implications - Results confirm that composite software should have the whole-face context visible to witnesses throughout construction. Though some software systems do this, there remain others that present features in isolation and these findings show that these systems are unlikely to be optimal. Originality/value - This is the first study to demonstrate the importance of a full-face context for the construction of facial composite images. Results are valuable to police forces and developers of composite software.

Climate change, whether gradual or sudden, has frequently been invoked as a causal factor to explain many aspects of cultural change during the prehistoric and early historic periods. Critiquing such theories has often proven difficult, not least because of the imprecise dating of many aspects of the palaeoclimate or archaeological records and the difficulties of merging the two strands of research. Here we consider one example of the archaeological record – peatland site construction in Ireland – which has previously been interpreted in terms of social response to climate change and examine whether close scrutiny of the archaeological and palaeoenvironmental records uphold the climatically deterministic hypotheses. We evaluate evidence for phasing in the temporal distribution of trackways and related sites in Irish peatlands, of which more than 3,500 examples have been recorded, through the examination of ~350 dendrochronological and 14C dates from these structures. The role of climate change in influencing when such sites were constructed is assessed by comparing visually and statistically the frequency of sites over the last 4,500 years with well-dated, multi-proxy climate reconstructions from Irish peatlands. We demonstrate that national patterns of “peatland activity” exist that indicate that the construction of sites in bogs was neither a constant nor random phenomenon. Phases of activity (i.e. periods in which the number of structures increased), as well as the ‘lulls’ that separate them, show no consistent correlation with periods of wetter or drier conditions on the bogs, suggesting that the impetus for the start or cessation of such activity was not climatically-determined. We propose that trigger(s) for peatland site construction in Ireland must instead also be sought within the wider, contemporary social background. Perhaps not surprisingly, a comparison with archaeological and palynological evidence shows that peatland activity tends to occur at times of more expansive settlement and land-use, suggesting that the bogs were used when the landscape was being more widely occupied. Interestingly, the lulls in peatland site construction coincide with transitional points between nominal archaeological phases, typically defined on the basis of their material culture, implying that there may indeed have been a cultural discontinuity at these times. © 2012 Elsevier Ltd.
