Public designs for a private genre : community and identity in the diary
Creators: name: McNeill, Laurie Ann
Publisher: name: University of British Columbia
Year: 2009

description: This study analyzes the contemporary diary in English as an autobiographical form that intersects public and private spheres, lives, and narratives. I examine how the diary performs social actions both personal and communal, and thus both "public" and "private." I take this inquiry to three distinct sites of contemporary diary writing, studying these texts within the particular circumstances of their production and reception. Using both autobiography and New Rhetorical genre theories, my analysis considers what contemporary diarists do with the contemporary diary, and how the diary adapts to fit these various functions. I incorporate linguistic pragmatic and discourse analysis to illuminate how identity construction and audience design operate at both the micro level of utterance and the macro level of genre. Chapter One discusses the diaries of May Sarton, Emily Carr, and P.K. Page, professional writers who use the "private" diary for both professional and personal functions. Chapter Two studies the diaries of Americans Natalie Crouter and Elizabeth Vaughan, and future Canadian Peggy Abkhazi, all civilian women who were interned in the Philippines and China by the Japanese during World War II. Trapped in a situation each clearly saw as historic, these women turned to the diary to keep public records that simultaneously served to write themselves back into subjectivity. In the third chapter, I consider diaries on the Internet, focusing on texts by Sara Achenbach, Justin Hall, and Steve Schalchlin. In analyzing these Weblogs, I discuss how the combination of the "private" diary and the public medium of the Internet challenges not only generic stereotypes but also traditional aesthetic and value systems that have determined whose life stories can be told. As all the texts I consider are published diaries, issues of authenticity, privacy, gender, and literariness are critical to this thesis, and each collection of texts illuminates how these concerns influence audience design, generic function, and textual production and reception. Throughout this study, I examine how the diary, a form long dismissed as artless, a-literary, "feminine," and consequently irrelevant, has in fact social and cultural, as well as personal, implications.

description: The possibility of a substantial reduction of weight and size of electrical generators is the main incentive behind the effort to develop superconducting armature windings based on coated conductors in the form of wide tapes with large aspect ratio. The main obstacle to the application of coated superconductors in stator windings is the large losses incurred due to the ac magnetic field produced by the rotor's dc coils of the field windings. In the range of frequencies typical for aircraft generators, the hysteretic losses in wide tapes are unacceptably high. They can be reduced by dividing the superconducting layer into multiple filaments separated by non-superconducting barriers. However, the lack of current sharing between the filaments makes the conductor vulnerable to the localized defects, so that a single blockage can impede the flow of transport current through the whole length of a given filament. We present estimates of reliability as well as the magnetization losses in multiply connected superconductors. In this type of superconducting tape, a sparse network of superconducting bridges, which allows for current sharing, connects the filaments. The trade-off between the different types of losses and the connectivity requirement imposes restrictions on the number of filaments and properties of the network of bridges.

description: The quantum dynamics away from equilibrium is of fundamental interest for interacting many-body systems. In this letter, we study tilted many-body systems using the effective Hamiltonian derived from the microscopic description. We first give general arguments for the density relaxation rate satisfying $1/τ\propto k^4$ for a large class of systems, including the Fermi Hubbard model case as observed in the the recent experiment [1]. Here $k$ is the wave vector of the density wave. The main ingredients are the emergence of the reflection symmetry and dipole moment conservation to the leading non-trivial order of the large tilted strength. To support our analysis, we then construct a solvable model with large local Hilbert space dimension by coupling sites discribed by the Sachdev-Ye-Kitaev models, where the density response can be computed explicitly. The the tilt strength and the temperature dependence of the subdiffusion constant are also discussed.

description: This paper provides an overview of the most recent developments on Russian cereal markets. A review of annual statistics on domestic production, trade, consumption, and storage of cereals reveals that the improvement in Russia’s net trade position cannot only be explained by increased productivity of grain producers. Exhausted storage capacities and lowered real trade costs after the devaluation of the Russian rouble in 1998 seem to have contributed to these developments. A computable general equilibrium model for Russia based on 1999 data was used for analyzing various economic developments and policy changes. The model simulations show that market protection in the short run, when the flexibility of labor and capital is restricted, may benefit Russian farmers. If, however, in the long run such structural rigidities can be abolished, a more liberal trade regime would also be positive for the domestic farm sector.

description: The N=2 spinning particle action describes the propagation of antisymmetric tensor fields, including vector fields as a special case. In this paper we study the path integral quantization on a one-dimensional torus of the N=2 spinning particle coupled to spacetime gravity. The action has a local N=2 worldline supersymmetry with a gauged U(1) symmetry that includes a Chern-Simons coupling. Its quantization on the torus produces the one-loop effective action for a single antisymmetric tensor. We use this worldline representation to calculate the first few Seeley-DeWitt coefficients for antisymmetric tensor fields of arbitrary rank in arbitrary dimensions. As side results we obtain the correct trace anomaly of a spin 1 particle in four dimensions as well as exact duality relations between differential form gauge fields. This approach yields a drastic simplification over standard heat-kernel methods. It contains on top of the usual proper time a new modular parameter implementing the reduction to a single tensor field. Worldline methods are generically simpler and more efficient in perturbative computations then standard QFT Feynman rules. This is particularly evident when the coupling to gravity is considered.

description: We study gravity coupled to scalar and fermion fields in the Einstein-Cartan framework. We discuss the most general form of the action that contains terms of mass dimension not bigger than four, leaving out only contributions quadratic in curvature. By resolving the theory explicitly for torsion, we arrive at an equivalent metric theory containing additional six-dimensional operators. This lays the groundwork for cosmological studies of the theory. We also perform the same analysis for a no-scale scenario in which the Planck mass is eliminated at the cost of adding an extra scalar degree of freedom. Finally, we outline phenomenological implications of the resulting theories, in particular to inflation and dark matter production.

description: Spectral pattern recognition is used to measure temperature and generate calibrated wavelength/frequency combs using a single silicon waveguide ring resonator. The ring generates two incommensurate interleaving TE and TM spectral combs that shift independently with temperature to create a spectral pattern that is unique at every temperature. Following an initial calibration, the ring temperature can be determined by recognizing the spectral resonance pattern, and as a consequence the wavelength of every resonance is also known. Two methods of pattern based temperature retrieval are presented. In the first method, the ring is locked to a previously determined temperature set-point defined by the coincidence of only two specific TE and TM cavity modes. Based on a prior calibration at the set-point, the ring temperature and hence all resonance wavelengths are then known and the resulting comb can be used as a wavelength calibration reference. In this configuration, all reference comb wavelengths have been reproduced within a 5 pm accuracy across an 80 nm range by using an on-chip micro-heater to tune the ring. For more general photonic thermometry, a spectral correlation algorithm is developed to recognize a resonance pattern across a 30 nm wide spectral window and thereby determine ring temperature continuously to 50 mK accuracy. The correlation method is extended to simultaneously determine temperature and to identify and correct for wavelength calibration errors in the interrogating light source. The temperature and comb wavelength accuracy is limited primarily by the linewidth of the ring resonances, with accuracy and resolution scaling with the ring quality factor.

Internal and external astrometric and photometric tests using existing optical photometry (U, B, and V from Massey's bright star catalog and I from the near-infrared sky survey DENIS) are used to confirm our observational uncertainty estimates. We fit stellar atmosphere models to the optical data to check the consistency of the photometry for individual stars across the passbands and to estimate the line-of-sight extinction. Finally, we use the estimated line-of-sight extinctions to produce an extinction map across the Large Magellanic Cloud, confirm the variation of extinction as a function of stellar population, and produce a simple geometrical model for the extinction as a function of stellar population.

A model-based approach to moral hazard in food chains - What contribution do principal-agent-models make to the understanding of food risks induced by opportunistic behaviour?

subject: traceability

description: Food risks may be caused by moral hazard, i.e. by opportunistic behaviour of upstream sellers who exploit the fact that many food product qualities remain uncertain to downstream buyers in the course of conventional market transactions (credence qualities). Due to this lack of market transparency buyers run the risk to pay premium prices for inferior products (quality risks); furthermore, they run the risk to use or consume substances which are harmful (health risks). Therefore, they will want to design optimal contracts and controls preventing opportunistic behaviour. Usually, however, buyers cannot contract contingent on the actions of upstream sellers because they cannot observe them directly (information asymmetry). Motivated by the obviously game-theoretic nature of the problem, we investigate the potential of principal-agent-models for the analysis of food risks induced by opportunistic behaviour. We identify a binary stochastic moral hazard model which is able to represent the microeconomic situation of buyers (principals) and sellers (agents) adequately. On the one hand, the model considers the remuneration costs which are needed to induce compliance. On the other hand, it accounts for direct costs and benefits of control as well as a limited traceability caused by the multiple agents setting of most food risk problems. If we know the costs of compliance, the stochastic relationship between the agent’s action and the product quality, and the traceability coefficient, we are able to determine the optimal control intensity and price for any cost of control function and predefined upper limit of the imposable sanction. For practical applications the main problem will be how to procure empirical data. The manageable data requirements of the binary model qualify it as a ready to use model for future applications: first, it can be used in positive analyses of food chains in order to detect the hot spots where food risks induced by opportunistic behaviour are to be expected for economic reasons. Secondly, it can be used in normative analyses in order to identify contractual designs which induce compliance at minimum costs. Thirdly, it can be used in order to compare the efficiency of different system structures taking into account the costs of change.

description: We prove implications among the conditions in the title for an inclusion of a C*-algebra A in a C*-algebra B, and we also relate this to several other properties in case B is a crossed product for an action of a group, inverse semigroup or an étale groupoid on A. We show that an aperiodic C*-inclusion has a unique pseudo-expectation. If, in addition, the unique pseudo-expectation is faithful, then A supports B in the sense of the Cuntz preorder. The almost extension property implies aperiodicity, and the converse holds if B is separable. A crossed product inclusion has the almost extension property if and only if the dual groupoid of the action is topologically principal. Topologically free actions are always aperiodic. If A is separable or of Type I, then topological freeness, aperiodicity and having a unique pseudo-expectation are equivalent to the condition that A detects ideals in all intermediate C*-algebras. If, in addition, B is separable, then all these conditions are equivalent to the almost extension property.

description: This article focuses on the social rate of return to plant breeding investment in Germany between 1980-2000. Starting point of the analysis is the development of total factor productivity which is decomposed into the effects of factor input and research investment. Information on investment in plant breeding have been obtained via questionnaires sent to both private plant breeding companies and public research organizations. The empirical results suggest significant underinvestment in German plant breeding research, as the calculated social rate of return is in the range of 16 to 28%.

description: This article provides several contributions to the general understanding of governance in networks and the achievement of private and common goals. A simple, integrated framework for understanding why firms collaborate and under which conditions they establish durable networks that succeed in achieving goals is provided. Network theory is extended by explicitly distinguishing between dyadic‐level governance and network‐level governance conditions, and by identifying exchange conditions that promote governance. This way issues as how networks evolve, how they are governed, and ultimately, how collective outcomes might be generated can be better comprehended. This is especially relevant to policy planners and those having a perspective that goes beyond the performance of individual organizations

description: The fact that we apparently live in an accelerating universe places limitations on where humans might visit. If the current energy density of the universe is dominated by a cosmological constant, a rocket could reach a galaxy observed today at a redshift of 1.7 on a one-way journey or merely 0.65 on a round trip. Unfortunately these maximal trips are impractical as they require an infinite proper time to traverse. However, calculating the rocket trajectory in detail shows that a rocketeer could nearly reach such galaxies within a lifetime (a long lifetime admittedly -- about 100 years). For less negative values of $w$ the maximal redshift increases becoming infinite for $w\geq -1/3$.

description: The purity, Tr(rho^2), measures how pure or mixed a quantum state rho is. It is well known that quantum dynamical semigroups that preserve the identity operator (which we refer to as unital) are strictly purity-decreasing transformations. Here we provide an almost complete characterization of the class of strictly purity-decreasing quantum dynamical semigroups. We show that in the case of finite-dimensional Hilbert spaces a dynamical semigroup is strictly purity-decreasing if and only if it is unital, while in the infinite dimensional case, unitality is only sufficient.

description: We investigate the causal hierarchy in various modified theories of gravity. In general relativity the standard causal hierarchy, (key elements of which are chronology, causality, strong causality, stable causality, and global hyperbolicity), is well-established. In modified theories of gravity there is typically considerable extra structure, (such as: multiple metrics, aether fields, modified dispersion relations, Horava-like gravity, parabolic propagation, etcetera), requiring a reassessment and rephrasing of the usual causal hierarchy. We shall show that in this extended framework suitable causal hierarchies can indeed be established, and discuss the implications for the interplay between "superluminal" propagation and causality. The key distinguishing feature is whether the signal velocity is finite or infinite. Preserving even minimal notions of causality in the presence of infinite signal velocity requires the aether field to be both unique and hypersurface orthogonal, leading us to introduce the notion of global parabolicity.

Transmission Expansion Planning Using Cycle Flows

description: The common linear optimal power flow (LOPF) formulation that underlies most transmission expansion planning (TEP) formulations uses bus voltage angles as auxiliary optimization variables to describe Kirchhoff's voltage law. As well as introducing a large number of auxiliary variables, the angle-based formulation has the disadvantage that it is not well-suited to considering the connection of multiple disconnected networks, It is, however, possible to circumvent these auxiliary variables and reduce the required number of constraints by expressing Kirchhoff's voltage law directly in terms of the power flows, based on a cycle decomposition of the network graph. In computationally challenging benchmarks such as generation capacity expansion with multi-period LOPF, this equivalent reformulation was shown in previous work to reduce solving times for LOPF problems by an order of magnitude. Allowing line capacity to be co-optimized in a discrete TEP problem makes it a non-convex mixed-integer problem. This paper develops a novel cycle-based reformulation for the TEP problem with LOPF and compares it to the standard angle-based formulation. The combinatorics of the connection of multiple disconnected networks is formalized for both formulations, a topic which has not received attention in the literature. The cycle-based formulation is shown to conveniently accommodate synchronization options. Since both formulations use the big-$M$ disjunctive relaxation, useful derivations for suitable big-$M$ values are provided. The competing formulations are benchmarked on a realistic generation and transmission expansion model of the European transmission system at varying spatial and temporal resolutions. The cycle-based formulation solves up to 31 times faster for particular cases, while averaging at a speed-up of factor 4.

description: The agri‐food sector and food consumption models have experienced both worldwide and in Europe a process of change that still appears ongoing. The main effects of this change are clearly visible in a whole series of new developments. The most interesting of these appears to be the role played by food product quality as a basis on which to implement modern marketing policies targeting an increasingly segmented market. This obviously makes it necessary for food consumption analysts to shed light on what it means, within today’s European and world consumption scenarios, to produce quality goods. On this point, in recent years the concept of quality may be said to have undergone rapid evolution. Quality has gone from meaning only intrinsic product attributes, hence synonymous with excellence, to a broader definition full of different meanings. Currently, it is widely recognised that, in modern consumer markets, food product quality is made up by both a set of intrinsic and extrinsic characteristics (Grunert, 2002) and by the way such characteristics are guaranteed and communicated to end consumers (Caswell and Joseph, 2007). As a result, purchase choices are affected not only by elements such as taste and price, but also by product range in the outlet, communication strategies, by the level of food safety, production process characteristics, nutritional aspects, origin and

description: Long-term geomagnetic activity presented by the aa index has been used to show that the heliospheric magnetic field has more than doubled during the last 100 years. However, serious concern has been raised on the long-term consistency of the aa index and on the centennial rise of the solar magnetic field. Here we reanalyze geomagnetic activity during the last 100 years by calculating the recently suggested IHV (Inter-Hour Variability) index as a measure of local geomagnetic activity for seven stations. We find that local geomagnetic activity at all stations follows the same qualitative long-term pattern: an increase from early 1900s to 1960, a dramatic dropout in 1960s and a (mostly weaker) increase thereafter. Moreover, at all stations, the activity at the end of the 20th century has a higher average level than at the beginning of the century. This agrees with the result based on the aa index that global geomagnetic activity, and thereby, the open solar magnetic field has indeed increased during the last 100 years. However, quantitatively, the estimated centennial increase varies greatly from one station to another. We find that the relative increase is higher at the high-latitude stations and lower at the low and mid-latitude stations. These differences may indicate that the fraction of solar wind disturbances leading to only moderate geomagnetic activity has increased during the studied time interval. We also show that the IHV index needs to be corrected for the long-term change of the daily curve, and calculate the corrected IHV values. Most dramatically, we find the centennial increase in global geomagnetic activity was considerably smaller, only about one half of that depicted by the aa index.

description: We present advancements in the design and development of in-vehicle infotainment systems that utilize gesture input and ultrasonic mid-air haptic feedback. Such systems employ state-of-the-art hand tracking technology and novel haptic feedback technology and promise to reduce driver distraction while performing a secondary task therefore cutting the risk of road accidents. In this paper, we document design process considerations during the development of a mid-air haptic gesture-enabled user interface for human-vehicle-interactions. This includes an online survey, business development insights, background research, and an agile framework component with three prototype iterations and user-testing on a simplified driving simulator. We report on the reasoning that led to the convergence of the chosen gesture-input and haptic-feedback sets used in the final prototype, discuss the lessons learned, and give hints and tips that act as design guidelines for future research and development of this technology in cars.

description: “Growing awareness among consumers about sustainability issues ‐ ranging from recycling to fair wages for workers ‐ are starting to shape consumer buying patterns” (Partos 2009). Especially for conscious consumers ethical and sustainable consumption are becoming mainstream. With regard to ethical consumption the popularity is shown for instance by a growing relevance of Causerelated Marketing (CrM) campaigns in Germany. CrM is an increasingly applied marketing tool, where product purchase leads to target‐oriented donations regarding a designated cause – promoted on the product by label. However, research reveals that German consumers are sceptic with regard to the amount of money spent and have doubts towards unselfish motives of firms. At present little information is provided in CrM campaigns on how much of the sales price is spent on the ‘cause’ by the respective organization. If the gap between the sum consumers assume to be contributed and the amount really spent by the companies is too large this could lead to mistrust among consumers once they become aware of this. In the long run, this might decrease willingness to pay for those products in general. Also, firms’ reputation could be harmed (see e.g. Webb and Mohr 1998). Against this background, we aim to answer the question of (1) how much consumers assume to be contributing to the ‘cause’ by purchasing the respective product and (2) whether this information is of relevance for the consumer. We investigate (i) whether consumers want products to carry a label indicating the percentage or absolute amount of money being spent on the ‘cause’, (ii) how much money should be contributed to the ‘cause’ in the case of CrM, and (iii) how much consumers think companies do actually spend on the ‘cause’. In this regard, we conducted a consumer survey (n=217) in Germany in 2009. Results show that (i) consumers want to be able to evaluate the efficiency of the CrM donation. 71% want this information given in percent and 63% would like to know the exact amount of money reaching the addressee. (ii) Regarding CrM results show that 46% of respondents would pay 5.00€ for a pound of CrM coffee if they can be sure that 20% reaches the ‘cause’. At the same time (iii) 54% of respondents believe that a maximum of 6% of the CrM price premium reaches the ‘cause’. Overall, consumers desire transparency with regard to CrM. Hence, our study enables marketers to develop efficient and effective consumer‐oriented communication strategies.

description: We study the efficiency of grain alignment by radiative torques (RATs) for an ensemble of irregular grains. The grains are modeled as ensembles of oblate and prolate spheroids, deformed as Gaussian random ellipsoids, and their scattering interactions are solved using numerically exact methods. We define the fraction of the grains that both rotate fast and demonstrate perfect alignment with grain long axes perpendicular to the magnetic field. We demonstrate that for typical interstellar conditions the degree of alignment arising from the RAT mechanism is significantly larger than that arising from the Davis-Greenstein (DG) mechanism based on paramagnetic relaxation. We quantify a factor related to the efficacy of alignment and show that it is related to a $q_\mathrm{max}$-factor of analytical model (AMO) of the RAT theory. Our results indicate that the RAT alignment can potentially be sufficiently strong and to explain observations even if grains do not have magnetic inclusions.

description: Two dimensional active fluids display a transition from turbulent to coherent flow upon decreasing the size of the confining geometry. A recent experiment suggests that the behavior in three dimensions is remarkably different; emergent flows transition from turbulence to coherence upon \emph{increasing} the confinement height to match the width. Using a simple hydrodynamic model of a suspension of extensile rod-like units, we provide the theoretical explanation for this puzzling behavior. Furthermore, using extensive numerical simulations supported by theoretical arguments, we map out the conditions that lead to coherent flows and elucidate the critical role played by the aspect ratio of the confining channel. The mechanism that we identify applies to a large class of symmetries and propulsion mechanisms, leading to a unified set of design principles for self-pumping 3D active fluids.

description: Food is a very sensitive area and the most intimate form of consumption. Consumer choice is known to be strongly affected by emotional factors usually not taken into account in economic analysis. At the same time it is clear that such emotional factors can affect consumer behaviour and market reactions above all when there are scandals and concerns. One of the emotional aspects that seems to dominate consumer behaviour in the food sector is so‐called magical thinking which leans on two different pillars: the contagion principle and the similarity principle. The contagion principle affects the concept of naturalness which, according to cognitive psychologists, is a key factor in determining consumer preferences. The main element stemming from this psychological approach is the generalised superiority which characterises those foods which are perceived as natural by consumers. It has also been observed that the specific kind of processing as well as the adding or subtracting of unnatural elements can modify the perception of naturalness and the degree of acceptability for food products. A survey which bore all such considerations in mind was conducted on a sample of 180 people interviewed shortly after their shopping trip to super‐ and hyper‐markets in the province of Naples. A questionnaire was submitted to sample in winter 2009. The questionnaire collected information about the perception of naturalness and its role in determining consumer preferences for different food products and different kinds of processing. A specific section of the questionnaire covered a case study and gathered information about the willingness to buy a specific food product: pasteurized and microfiltered fresh cow’s milk. This product has the same nutritional qualities and the same taste as fresh pasteurized cow’s milk, but has a longer shelf‐life due to specific technology. On the basis of the results and by using a binary model, consumer willingness to purchase the specific milk was estimated. The findings permit an analysis of the role that both different types of product processing or manipulation and the various forms of innovation can play in determining levels of trust and modifying the discrepancy between objective and perceived quality.

description: In this work we present the results of an experiment to locally resolve the spin Seebeck effect in a high-quality Pt/YIG sample. We achieve this by employing a locally heated scanning thermal probe to generate a highly local non-equilibrium spin current. To support our experimental results, we also present a model based on the non-equilibrium thermodynamic approach which is in a good agreement with experimental findings. To further corroborate our results, we index the locally resolved spin Seebeck effect with that of the local magnetisation texture by MFM and correlate corresponding regions. We hypothesise that this technique allows imaging of magnetisation textures within the magnon diffusion length and hence characterisation of spin caloritronic materials at the nanoscale.

description: Fresh fruits are always recommended as ingredients in healthiest diets. However, there is a tendency for consumers to move their consumption towards transformed fruits, which are integrated in many food products. Quite commonly fresh fruits are difficult to handle and store but they also do not have regular quality when they reach consumers. There are many other elements besides the physical characteristics, which are very important for consumers, and they can be promoted through marketing actions. It is very important to understand why consumers make elections of fresh fruits in order to increase their consumption. The aim of this study is to understand how consumers make their purchasing choices based on the most important peaches’ attributes and levels. In Spain there are 20 fruits with the Protected Designation of Origin (PDO) label. Among those PDOs, only one brand certifies the peaches’ origin and it is called “Calanda Peaches”. This fruit has been selected to test several hypotheses about consumers’ fruits choice. The survey collects information from questionnaires applied to PDO Calanda peaches` consumers that were attending two hypermarkets in Zaragoza city, in 2009. An attribute‐level best‐worst experiment was undertaken, respondents stated the most and the least important characteristic in their purchasing. Each characteristic, or alternative, is an attribute associated to a level of that attribute. In our case, nine hypothetical products were presented from different combinations of 4 attributes, with 3 levels in each attribute, (price: 1.2 €/kg, 2.4 €/kg and 3.6 €/kg; origin: PDO Calanda, non PDO Calanda and non Calanda; packaging : bulk, conventional packaging and active packaging; and fruit size: small, medium and big) to allow main effects estimation. Data were analysed using Weighted Least Squares (WLS) by in Best‐Worst Paired (BWP) and Best‐Worst Marginal (BWM) methods. Both models allow the attribute and attribute’s levels impact estimation on consumer purchase decision. They also have similar measurement properties, but as Paired models have more observations per respondent, they present smaller standard errors. Results show that both models have good performance. Consumers give different weights to the attributes when they buy peaches. There is an overriding influence of the origin especially for the attribute‐level Calanda in comparison with the rest.
