Dismantling the Spatiality of Heaven in the Prayer Poems of Emily Dickinson

I identify three significant components of Heaven’s spatiality that determine the boundaries of and conditions for “legitimate” spiritual experience, all of which are embodied in what Dickinson calls “the apparatus” of prayer (Fr 632). First, the locations of Heaven and Earth are determinable, absolute, and inflexible, thus marking the distance that separates human from God as static and constant; second, in order to engage God, the supplicant must turn towards Heaven (and away from Earth); and third, specific spatial and emotional protocol are established by assigning God socially constructed roles such as King or Father. Dickinson dismantles the spatiality of Heaven in her poems and letters by undoing these three components; yet even in the act of disassembling, she embraces and recycles their respective ideologies as a way of claiming sole ownership of her religiosity

SME Performance: A Case for Internal Consistency

We develop the theoretical arguments for a contingent path relationship among variables representing the environment, capabilities, strategic orientation, and firm performance. The premise underpinning our study is that internal consistency or fit among contingent relationships yields higher performance levels. Structural equation modeling allows for the statistical examination of multiple relationships simultaneously to test our hypotheses. We find support for the notion that internally consistent paths lead to higher levels of performance for a sample of 181 mid-western small and medium-sized manufacturing firms. A discussion of the implications for these findings with respect to managerial practice and future research is provided

The interplay of strategic orientations and their influence on SME performance

This paper examines the role that learning orientation plays with respect to entrepreneurial orientation, market orientation, and, ultimately, the performance of small and medium-sized enterprises SMEs. Previous research indicated mixed findings in regards to the relationship of these strategic orientations and firm performance. Instead of just direct influences to performance, we examine if learning orientation is an antecedent to market and entrepreneurial orientation. We suggest that in this way, their influence to SME performance would be more accurately predicted. We argue that learning orientation reflects the overall values of the organization, whereas entrepreneurial and market orientations are more action-oriented firm behaviors. Learning orientation would likely set the stage for the requisite actions implied in market and entrepreneurial orientation. Direct effect and mediated effects hypotheses between these strategic orientations are tested on a sample of SME manufacturing firms and their performance. Findings indicate that learning and entrepreneurial orientation directly influence SME performance. However, when learning orientation and its effects are mediated by market and entrepreneurial orientation, direct effects disappear when testing this model. The study offers insight into relationships between various strategic orientations, as to how and when they might influence SME performance

Evolution in controls methods for the SPS power converters

In common with much accelerator specific material, there is a constant need to improve both hardware and software for power converter control. Maintenance and performance improvements of older systems have become extremely tedious and in some areas impossible. By using modern real-time software and the latest high-performance processors, such problems should be substantially reduced. This paper describes the software concepts and the hardware chosen for the upgrade of the existing facilities. Using the UNIX compatible LynxOS real time kernel, running on a PowerPC 603 in a VME environment, this new approach provides excellent performance while retaining the desired flexibility for future enhancements. The 64 channel system is implemented as a set of cooperating processes, several of which are multi-threaded. Processes include analogue function generation, analogue measurement and digital I/O, all of which are accurately scheduled by the accelerator timing system. This generalised structure, which performs complex sequences of operations is described in detail, as well as how it can be adapted to a wide variety of accelerator tasks

The All-digital Approach to LHC Power Converter Current Control

The design of the LHC machine imposes severe demands upon the control of current in the 1700 magnet circuits. This has required the use of novel methods for the control of individual power converters and of the magnet current control system as a whole. This paper will review the chosen hardware and software methods and architectures. The digital regulation techniques used to achieve the overall targets for short-term stability (<3ppm) and reproducibility (<10ppm) of the 24 principal LHC circuits will be discussed. While the proposed system architecture will follow the canonical three-layer design, so successfully exploited in LEP, the software will be far from traditional. This software must be more reliable and maintainable than ever before, and will need to integrate with advanced object-oriented applications via commercial middleware. These challenges will be faced by applying object-oriented techniques throughout the system and by harnessing the power of XML for system definition

Radiocarbon Isotopic Classification of Deep Tropical Forest Soils

Tropical forest soils have an important role in global carbon (C) stocks. Small changes in the cycling of C could drastically affect atmospheric carbon dioxide (CO2) concentrations and active cycling of carbon in a forest community. Currently, little is understood of how tropical forest soils will respond to the increasing global temperatures. To examine the effects of warming/ drought on losses of older versus younger soil C pools, we implemented radiocarbon (14C) isotopic characterization of various soil plot samples and depths from the Luquillo Experimental Forest, Puerto Rico. 14C was measured using Accelerated Mass Spectrometry (AMS) from catalytically condensed carbon in order to examine the initial carbon stocks of the test plots. This examination was done in order to determine the age of the carbon in the soil plots before implementation of a long term warming experiment. In addition to determining the age of the soil C, the samples were submitted to a Density Fractionation Process to obtain varying aggregate fractions. These were also submitted to AMS for mean residence time of the C stocks. The soil 14C was significantly different in the Heavy and Free Light density fractions. This implies that the soil C turnover increases as you near the top depth of the soil pit samples. The results will be used to establish the initial composition of the sample soils for a warming experiment that will model future changes in climate

Crowd- and Community-fuelled Archaeological Research. Early Results from the MicroPasts Project

The MicroPasts project is a novel experiment in the use of crowd-based methodologies to enable participatory archaeological research. Building on a long tradition of offline community archaeology in the UK, this initiative aims to integrate crowd-sourcing, crowd-funding and forum-based discussion to encourage groups of academics and volunteers to collaborate on the web. This paper will introduce MicroPasts, its aims, methods and initial results, with a particular emphasis on project evaluation. The evaluative work conducted over the first few months of the project already demonstrates the potential for crowd-sourced archaeological 3D modelling, especially amongst younger audiences, next to more traditional kinds of crowd-sourcing such as transcription. It has also allowed a comparative assessment of different methods for sustaining contributor participation through time and a discussion of their implications for the sustainability of the MicroPasts project and (potentially) other archaeological crowd-sourcing endeavours

Optical frequency comb Fourier transform spectroscopy of formaldehyde in the 1250 to 1390 cm−1 range: Experimental line list and improved MARVEL analysis

We use optical frequency comb Fourier transform spectroscopy to record high-resolution, low-pressure, room-temperature spectra of formaldehyde (H212C16O) in the range of 1250 to 1390 cm−1. Through line-by-line fitting, we retrieve line positions and intensities of 747 rovibrational transitions: 558 from the ν6 band, 129 from the ν4 band, and 14 from the ν3 band, as well as 46 from four different hot bands. We incorporate the accurate and precise line positions (0.4 MHz median uncertainty) into the MARVEL (measured active vibration-rotation energy levels) analysis of the H2CO spectrum. This increases the number of MARVEL-predicted energy levels by 82 and of rovibrational transitions by 5382, and substantially reduces uncertainties of MARVEL-derived H2CO energy levels over a large range: from pure rotational levels below 200 cm−1 up to multiply excited vibrational levels at 6000 cm−1. This work is an important step toward filling the gaps in formaldehyde data in the HITRAN database

A structural role for arginine in proteins: Multiple hydrogen bonds to backbone carbonyl oxygens

We propose that arginine side chains often play a previously unappreciated general structural role in the maintenance of tertiary structure in proteins, wherein the positively charged guanidinium group forms multiple hydrogen bonds to backbone carbonyl oxygens. Using as a criterion for a “structural” arginine one that forms 4 or more hydrogen bonds to 3 or more backbone carbonyl oxygens, we have used molecular graphics to locate arginines of interest in 4 proteins: Arg 180 in Thermus thermophilus manganese superoxide dismutase, Arg 254 in human carbonic anhydrase II, Arg 31 in Streptomyces rubiginosus xylose isomerase, and Arg 313 in Rhodospirillum rubrum ribulose‐1,5‐bisphosphate carboxylase/oxygenase. Arg 180 helps to mold the active site channel of superoxide dismutase, whereas in each of the other enzymes the structural arginine is buried in the “mantle” (i.e., inside, but near the surface) of the protein interior well removed from the active site, where it makes 5 hydrogen bonds to 4 backbone carbonyl oxygens. Using a more relaxed criterion of 3 or more hydrogen bonds to 2 or more backbone carbonyl oxygens, arginines that play a potentially important structural role were found in yeast enolase, Bacillus stearothermophilus glyceraldehyde‐3‐phosphate dehydrogenase, bacteriophage T4 and human lysozymes, Enteromorpha prolifera plastocyanin, HIV‐1 protease, Trypanosoma brucei brucei and yeast triosephosphate isomerases, and Escherichia coli trp aporepressor (but not trp repressor or the trp repressor/operator complex). In addition to helping form the active site funnel in superoxide dismutase, the structural arginines found in this study play such diverse roles as stapling together 3 strands of backbone from different regions of the primary sequence, and tying α‐helix to α‐helix, βturn to β‐turn, and subunit to subunit.
