Behind the Seams: An Ethnographic Study of the Performative Nature of Theatrical Costumes

Actors are said to bring a play to life, but what about the garments that they wear? Like set production, light design, and direction, the role of the costume plays an important part in informing and enchanting the audience. However, this is not all that they do. This paper acts as an in-depth examination of the culture of costume creation and destruction at Gettysburg College, researching their roles as garments, as well as how the garments themselves act around others. Imbued with their own set of responsibilities, the costumes are expected to behave certain ways, perform specific functions, and put on a show of their own. Through 20 hours of ethnographic research, this paper seeks to show that the costumes are not just as single component of the theatrical experience, but instead an integral performer in the social construction of the story itself

Statistical effects in the solar activity cycles during AD 1823-1996

General statistical properties of solar activity cycles during the period AD 1823–1996—including the Gnevyshev-Ohl and Waldmeier effects as well as an amplitude-period effect—were analyzed using Wolf number, group sunspot number, and extended total sunspot area series. It was found out that the Gnevyshev-Ohl effect GO2 (the positive correlation between intensity of the even cycles 2N and intensity of the odd cycles 2N+1) and the Waldmeier effect W2 (the anticorrelation between rise times of sunspot cycles and their amplitudes) are the most universal and robust features of the solar cycle. Other statistical relations were found appreciably sensitive to the selection of solar index, the interval of analysis, and the way of the cycle feature determination.</jats:p

Bivalve associations of the Cannonball Formation (Paleocene, Danian) of North Dakota

The Cannonball Formation (Paleocene, Danian) is best exposed in southwest-central North Dakota. Here, two major lithotypes, mudstone and sandstone, occur. In this area, the Cannonball can be informally subdivided into four lithologic units: lower (primarily thinly-bedded sandstone and mudstone), lower-middle (sandstone), upper-middle (mudstone), and upper (sandstone). The Cannonball is also exposed in southwestern North Dakota where it occurs as two mudstone tongues (upper and lower). During July and August, 1982, thirteen Cannonball outcrops were studied. Bivalves, along with other macrofossils, were collected quantitatively in an attempt to determine fossil species dominance. Rock samples were also collected and analyzed for textural characteristics and organic carbon content. In addition, R-mode and Q-mode cluster analyses were done using the reported occurrences of 20 bivalve species, along with other macrofossils, from 97 localities in North Dakota. Five bivalve associations are defined: Ostrea-Corbula-Corbicula, Crassostrea-Corbicula-Corbula, Isognomon, Glycymeris-Arctica, and Crassatella-Nucula associations. One sub-association, the modified Crassatella-Nucula association, and a biotic association of Ophiomoroha Crab-Driftwood-Shark Teeth, are also defined. These associations aid in the interpretation of the relationships of Cannonball lithologic units and depositional environments. The Ostrea-Corbula-Corbicula association (lower tongue) and the Crassostrea-Corbicula-Corbula association (upper tongue) contain low-diversity faunas that are characteristic of brackish-water environments associated with· lagoons. The Isognomon association, found in the lower Cannonball unit, occurs in muddy sandstone rich in organic material. The abundance of Isognomon, a large, thick-shelled, suspension-feeding bivalve, along with the lack of other macrofossils, suggests an environment where conditions were prohibitive to most organisms. A shallow-water environment associated with a tidal flat is proposed. The Glycyrneris-Arctica association, found in well-sorted sandstone in the lower-middle unit, is dominated by suspension-feeding bivalves. The presence of Glycymeris, a bivalve well adapted to high-energy conditions, indicates a nearshore, wave-agitated beach environment. The Ouhiomorpha-Crab-Driftwood-Shark Teeth association also occurs in well-sorted sandstone but is not restricted to any Cannonball unit. The association of these nearshore inhabitants suggests a beach environment where deposition took place in the vicinity of the strandline. The Grassatella-Nucula association occurs in the lower-middle unit in muddy sandstone. This association has high diversity and both deposit-feeding and suspension-feeding bivalves are present suggesting a stable, subtidal environment. The modified Crassatella-Nucula associa tion contains bivalves similar to the veritable Crassatella-Nucula association but lacks the high diversity. The modified association occurs in variable lithology and is not restricted to any Carmonball lithologic unit. It also represents a subtidal environment; however, conditions were probably not conducive to high-diversity communities. Two major transgressions and regressions occurred during Cannonball time. Based on the proposed associations, it seems likely that deposition of the brackish-water tongues in southwestern North Dakota is correlative with two major transgressive events in southwest-central North Dakota

Regenerative maintenance in buildings

Abstract. University Properties of Finland is involved in European Cost Restore project, where the main point is to survey strong and regenerative sustainable development’s challenges in built environment. Starting point of the project is view, where the built environment is not sustainable just being “less bad”, for example more energy efficient, than before. Instead built environment must be in the future “better” and it must aim at strengthened and regenerative sustainability. The aim of the work is to do comprehensive literary survey of evolution in real estate service and maintenance of the properties. The whole is approached first as a level of whole surrounding natural system, second as a level of location of property and third as a level of the property. First this work concentrate surrounding natural system, second regenerative building and last regenerative maintenance. The focus before anything is at campus areas, commercial and office premises, but the views might be applicable more widely.Regeneratiivinen kiinteistöjen ylläpito. Tiivistelmä. SuomenYliopistokiinteistöt Oy on mukana eurooppalaisessa COST RESTORE -verkostohankkeessa, jossa kartoitetaan vahvan ja uudistavan kestävän kehityksen haasteita rakennetussa ympäristössä. Keskeisenä lähtökohtana on näkemys, että rakennettu ympäristö ei ole kestävä olemalla "vähemmän huono" eli esimerkiksi vähemmän energiatehokkaampi kuin aiemmin. Sen sijaan rakennetun ympäristön on oltava tulevaisuudessa "enemmän hyvä" ja sen on pyrittävä sekä vahvistamaan että uudistavaan kestävyyteen. Tämän työn päätavoitteena on tehdä kattava kirjallisuuskatsaus kestävän kehityksen evoluutiosta kiinteistöpalveluissa ja kiinteistön ylläpidossa. Kokonaisuutta lähestytään kaupunkiympäristön kontekstissa, kiinteistön sijainnin tasolla ja kiinteistön tasolla. Ensiksi työssä keskitytään ympäröivään luontosysteemiin, toiseksi regeneratiiviseen rakennukseen ja kolmanneksi regeneratiiviseen ylläpitoon. Työssä keskitytään toimi- ja liiketiloihin sekä kampusalueisiin, mutta työssä esiteltävät keinot ovat sovellettavissa mahdollisesti laajemminkin

Modelling the Value Adding Attributes of Real Estate to the Wealth Maximization of the Firm

Firms develop strategies to help them achieve their primary goal of maximizing the wealth of the shareholders. These strategies should define the supporting role corporate real estate management plays; however current theory and practice do not adequately identify the direct and indirect methods by which corporate real estate management (CREM) adds value to the firm. We develop a model of how real estate adds value to the firm to help fill this void. This model can be then used to develop more precise and complete metrics to measure the value real estate adds to the firm.

The impact of beam deconvolution on noise properties in CMB measurements: Application to Planck LFI

We present an analysis of the effects of beam deconvolution on noise properties in CMB measurements. The analysis is built around the artDeco beam deconvolver code. We derive a low-resolution noise covariance matrix that describes the residual noise in deconvolution products, both in harmonic and pixel space. The matrix models the residual correlated noise that remains in time-ordered data after destriping, and the effect of deconvolution on it. To validate the results, we generate noise simulations that mimic the data from the Planck LFI instrument. A $\chi^2$ test for the full 70 GHz covariance in multipole range $\ell=0-50$ yields a mean reduced $\chi^2$ of 1.0037. We compare two destriping options, full and independent destriping, when deconvolving subsets of available data. Full destriping leaves substantially less residual noise, but leaves data sets intercorrelated. We derive also a white noise covariance matrix that provides an approximation of the full noise at high multipoles, and study the properties on high-resolution noise in pixel space through simulations.Comment: 22 pages, 25 figure
