Developing temporary manufacturing facilities for residential building: a case of the modern flying factory

The building industry is often berated for its short comings in meeting up with the demand for the provision of new housing. Addressing the need for new housing stock is a challenge that has led to debates among professional bodies, the construction sector, housing industry and government. The introduction of new manufacturing technologies is often offered as a solution, but the challenges of increasing the amount of off-site construction in residential building are well known and well-rehearsed. The modern flying factory (MFF) is a concept that involves the manufacture of specific components or modules in temporary off- or near- site locations using relatively simple and quick to set up and dismantle technologies and processes. The aim is to produce short batches and hence achieve some of the benefits of off-site manufacture on a much smaller scale than in dedicated factory environments. A case study of a modern flying factory being set up to produce pre-assembled utility cupboards for a large residential development in London is presented, involving participant observation and informal interviews with key actors on the design and operationalising of the process. The case reveals that although there are costs, efficiency and health and safety benefits to using MFF approaches, there are also challenges to overcome over the time required to set up and establish the process for relatively short runs, and in evaluating whether the MFF or traditional site based production is most effective for particular aspects of projects.

Projecting social and discursive identities through code-switching on facebook: the case of Greek Cypriots

Two varieties of Greek are spoken on the island of Cyprus: the local dialect, namely the Greek-Cypriot Dialect (GCD), and Standard Modern Greek (SMG). English is also influential, as Cyprus was an English colony until 1960. The dialect is rarely employed for everyday written purposes; however, it is now evident in computer-mediated communication (CMC). As a contribution to the field of code-switching in writing, this study examines how Greek-Cypriot internet users employ GCD, SMG, and English in their Facebook interactions. In particular, we investigate how identities (discursive and social) are performed and indexed through the linguistic choices of Greek-Cypriot internet users. The findings indicate that switches to GCD add a humorous tone and express solidarity and informality. SMG is mostly used for ‘official’ statements, and it is preferred by mature internet users, while English is used with expressions of affect and evaluative comments.

Introduction: the legacy of Greek political thought

This Introduction offers context for the individual papers by examining the intersections and productive tensions between political thought and classical reception studies. While Plato and Aristotle have long been privileged interlocutors for political philosophers, classical reception studies has pluralised both this ancient canon and given rise to a more complex understanding of the modern heirs of ancient political thought. Similarly, the insights of studying the history of political texts and ideas across a longer tradition calls into question the fixity of concepts such as democracy, empire and political freedom. Indeed, we query the very notion of tradition by emphasising how the past has been repeatedly constructed and reconstructed in divergent modern political discourses and conversely how modern political theories and realities have been shaped and reshaped by an idea of antiquity. The Introduction closes with a brief survey of the collected papers.

Investor disagreement: the modern approach

Disagreement between economists is a well know fact. However, it took a long time for this concept to be incorporated in economic models. In this survey, we review the consequences and insights provided by recent models. Since disagreement between market agents can be generated through different hypotheses, the main differences between them are highlighted. Finally, this work concludes with a short review of nowcasting using google trends, emphasizing advances connecting both literatures.

Seven stories: location based story-delivery system

Location aware content-based experiences have a substantial tradition in HCI, several projects over the last two decades have explored the association of digital media to specific locations or objects. However, a large portion of the literature has little focus on the creative side of designing of the experience and on the iterative process of user evaluations. In this thesis we present two iterations in the design and evaluation of a location based story delivery system (LBSDS), inspired by local folklore and oral storytelling in Madeira. We started by testing an already existing location based story platform, PlaceWear, with short multimedia clips that recounted local traditions and folktales, to this experience we called iLand. An initial evaluation of iLand, was conducted; we shadowed users during the experience and then they responded to a questionnaire. By analyzing the evaluation results we uncovered several issues that informed the redesign of the system itself as well as part of the story content. The outcome of this re design was the 7Stories experience. In the new experience we performed the integration of visual markers in the interface and the framing of the fragmented story content through the literary technique of the narrator. This was done aiming to improving the connection of the audience to the physical context where the experience is delivered. The 7Stories experience was evaluated following a similar methodology to the iLand evaluation but the user’s experience resulted considerably different; because of the same setting for the experience in both versions and the constancy of the most of the content across the two versions we were able to assess the specific effect of the new design and discuss its strengths and shortcomings. Although we did not run a formal and strict comparative test between the two evaluations, it is evident from the collected data how the specific design changes to our LBSDS influenced the user experience.

Quantitative estimates of time-averaging in terebratulid brachiopod shell accumulations from a modern tropical shelf

Quantitative estimates of time-averaging in marine shell accumulations available to date are limited primarily to aragonitic mollusk shells. We assessed time-averaging in Holocene assemblages of calcitic brachiopod shells by direct dating of individual specimens of the terebratulid brachiopod Bouchardia rosea. The data were collected from exceptional (brachiopod-rich) shell assemblages, occurring surficially on a tropical mixed carbonate-siliciclastic shelf (the Southeast Brazilian Bight, SW Atlantic), a setting that provides a good climatic and environmental analog for many Paleozoic brachiopod shell beds of North America and Europe. A total of 82 individual brachiopod shells, collected from four shallow (5-25 m) nearshore (<2.5 km from the shore) localities, were dated by using amino acid racemization (D-alloisoleucine/L-isoleucine value) calibrated with five AMS-radiocarbon dates (r(2) = 0.933). This is the first study to demonstrate that amino acid racemization methods can provide accurate and precise ages for individual shells of calcitic brachiopods.The dated shells vary in age from modern to 3000 years, with a standard deviation of 690 years. The age distribution is strongly right-skewed: the young shells dominate the dated specimens and older shells are increasingly less common. However, the four localities display significant differences in the range of time-averaging and the form of the age distribution. The dated shells vary notably in the quality of preservation, but there is no significant correlation between taphonomic condition and age, either for individual shells or at assemblage level.These results demonstrate that fossil brachiopods may show considerable time-averaging, but the scale and nature of that mixing may vary greatly among sites. Moreover, taphonomic condition is not a reliable indicator of pre-burial history of individual brachiopod shells or the scale of temporal mixing within the entire assemblage. The results obtained for brachiopods are strikingly similar to results previously documented for mollusks and suggest that differences in mineralogy and shell microstructure are unlikely to be the primary factors controlling the nature and scale of time-averaging. Environmental factors and local fluctuations in populations of shell-producing organisms are more likely to be the principal determinants of time-averaging in marine benthic shelly assemblages. The long-term survival of brachiopod shells is incongruent with the rapid shell destruction observed in taphonomic experiments. The results support the taphonomic model that shells remain protected below (but perhaps near) the surface through their early taphonomic history. They may be brought back up to the surface intermittently by bioturbation and physical reworking, but only for short periods of time. This model explains the striking similarities in time-averaging among different types of organisms and the lack of correlation between time-since-death and shell taphonomy.

Book Review of Improved Earth: Prairie Space as Modern Artefact, 1869-1944 by Rod Bantjes

In this short but suggestive study, sociologist Rod Bantjes examines how contending visions of modernity shaped the social and physical landscapes of the Canadian prairies. "[B]oth statesmen and prairie farmers were infused with the modernist spirit of innovation, the will creatively (and destructively) to transform their worlds," Bantjes argues. His provocative view of farmers as agents of modernity reflects recent scholarship that seeks to explore "multiple modernities," or the notion that ideas and practices of modernism must be regarded not as monolithic but rather as contested and multivocal, and must be examined in their historical and geographical contexts.

Color stability of modern composites subjected to different periods of accelerated artificial aging

The aim of this study was to evaluate the color stability of composites subjected to different periods of accelerated artificial aging (AAA). A polytetrafluorethylene matrix (10 x 2 mm) was used to fabricate 24 test specimens of three different composites (n=8): Tetric Ceram (Ivoclar/Vivadent); Filtek P90 and Z250 (3M ESPE), shade A3. After light activation for 20 s (FlashLite 1401), polishing and initial color readout (Spectrophotometer PCB 687; BYK Gardner), the test specimens were subjected to AAA (C-UV; Comexim), in 8-h cycles: 4 h exposure to UV-B rays at 50°C and 4 h condensation at 50°C. At the end of each cycle, color readouts were taken and the test ended when the mean value of ΔE attained a level ≥3.30. Tetric Ceram presented alteration in ΔE equal to 3.33 in the first aging cycle. For Filtek P90 and Z250, two (ΔE=3.60) and four (ΔE=3.42) AAA cycles were necessary. After each cycle, there was a reduction of luminosity in all the samples (ΔL). It was concluded that a short period of AAA was sufficient to promote clinically unacceptable color alteration in composites, and that this alteration was material-dependent.

Analysis of eruptive and seismic sequences to improve the short-and long-term eruption forecasting

Forecasting the time, location, nature, and scale of volcanic eruptions is one of the most urgent aspects of modern applied volcanology. The reliability of probabilistic forecasting procedures is strongly related to the reliability of the input information provided, implying objective criteria for interpreting the historical and monitoring data. For this reason both, detailed analysis of past data and more basic research into the processes of volcanism, are fundamental tasks of a continuous information-gain process; in this way the precursor events of eruptions can be better interpreted in terms of their physical meanings with correlated uncertainties. This should lead to better predictions of the nature of eruptive events. In this work we have studied different problems associated with the long- and short-term eruption forecasting assessment. First, we discuss different approaches for the analysis of the eruptive history of a volcano, most of them generally applied for long-term eruption forecasting purposes; furthermore, we present a model based on the characteristics of a Brownian passage-time process to describe recurrent eruptive activity, and apply it for long-term, time-dependent, eruption forecasting (Chapter 1). Conversely, in an effort to define further monitoring parameters as input data for short-term eruption forecasting in probabilistic models (as for example, the Bayesian Event Tree for eruption forecasting -BET_EF-), we analyze some characteristics of typical seismic activity recorded in active volcanoes; in particular, we use some methodologies that may be applied to analyze long-period (LP) events (Chapter 2) and volcano-tectonic (VT) seismic swarms (Chapter 3); our analysis in general are oriented toward the tracking of phenomena that can provide information about magmatic processes. Finally, we discuss some possible ways to integrate the results presented in Chapters 1 (for long-term EF), 2 and 3 (for short-term EF) in the BET_EF model (Chapter 4).

Ogawa Mimei's Children's Stories: A Case Study of the Rise of Childhood in the Context of Westernization and Japanese Modernization

In this thesis, I examine the influences of westernization, the tension between Japanese modernity and tradition, and the stories of Hans Christian Andersen on Ogawa Mimei’s children’s stories. I begin the body of my thesis with a brief historical background of Japan, beginning with the start of the Meiji period in 1868. Within the historical section, I focus on societal and cultural elements and changes that pertain to my thesis. I also include the introduction of Hans Christian Andersen in Japan. I wrap up the historical section by a description of Ogawa’s involvement in the Japanese proletarian literature movement and the rise of the Japanese proletarian children’s literature movement. Then, I launch into an analysis of Ogawa’s works categorized by thematic elements. These elements include westernization, class conflict, nature and civilization, religion and morals, and children and childhood. When relevant, I also compare and contrast Ogawa’s stories with Andersen’s. In the westernization section, I show how some of Ogawa’s stories demonstrate contact between Japan and the West. In the Class Conflict section, I discuss how Ogawa views class through a socialist lens, whereas Andersen does not dispute class distinctions, but encourages his readers to attempt an upward social climb. In the nature and civilization section, I show how Ogawa and Andersen share common opinions on the impact of civilization on nature. In the religion and morals section, I show how Ogawa incorporates religion, including Christianity, into vii his works. Andersen utilizes religion in a more overt manner in order to convey morals to his audience. Both authors address religious topics like the concept of the afterlife. Finally, in children and childhood, I demonstrate how both Ogawa and Andersen treat their child protagonists and use them and their situations to instruct their readers. Through this case study, I show how westernization and the tensions between Japanese modernization and tradition led to the rise of the proletarian children’s literature movement, which is exemplified by Ogawa’s stories. The emergence of the proletarian children’s literature movement is an indication of the establishment of a new concept of childhood in Japan. Writers like Ogawa Mimei attempted to write children’s stories that represented the new Japanese culture that was a result of adapting Western ideals to fit Japanese society. Some of Ogawa’s stories are a direct commentary on his opinion of Japanese interaction with the West. By comparing Ogawa’s and Andersen’s stories, I demonstrate how Ogawa borrows certain Western elements and possibly responds directly to Andersen. Ogawa also addresses some of the same topics as Andersen, yet their reactions are not always the same. What I find in my analysis supports my thesis that Ogawa is able to maintain Japanese tradition while infusing his children’s stories with Western and modern elements. In doing so, he reflects a largely popular social and cultural practice of his time.
