description: H επέμβαση αφορά στην ανάδειξη ενός σημαντικού αρχαιολογικού χώρου, του
Κάστρου Μαΐνη και της ευρύτερης περιοχής του, που δύναται να χαρακτηριστεί ως παλίμψηστο διαφόρων ιστορικών εποχών. Το ζήτημα που διερευνάται είναι οι δυνατότητες ενεργοποίησης των αρχαιολογικών χώρων του τόπου. Η συγκεκριμένη έρευνα προτείνει τη διαλεκτική σχέση μεταξύ του παρελθόντος, που εμφανίζεται ως ένα φυσικό ίχνος της γης, και του παρόντος. Η διπλωματική κινείται πάνω στις έννοιες της λατόμευσης, εκσκαφής & συσσώρευσης.
Η περιοχή μελέτης αφορά:
Τον αρχαιολογικό χώρου του Κάστρου Μαΐνη.
Το σύμπλεγμα των αλυκών στο Τηγάνι.
Το αρχαίο λατομείο του Αγ. Προκοπίου.
Την εκβολή του ξεροχείμαρρου του Μεζάπου.

Οι βασικοί άξονες του θέματος είναι:
_Δημιουργία επεμβάσεων βασιζόμενες στην έννοια της λατόμευσης
ως θεωρητική έννοια και διαδικασία,
μέσω της εκσκαφής και της συσσώρευσης.
_Ο επαναπροσδιορισμός της τοπιογραφίας ακολουθώντας τα ίχνη του παρελθόντος (αποκαλύπτονται τα ιερά ορύγματα της γης,
αναδεικνύονται τα αρχαία μονοπάτια-πορείες, αποκαθίστανται τα αρχαία μνημεία).
-Η ενίσχυση των προϋπαρχόντων φυσικών χαρακτηριστικών του τόπου
(επισήμανση των συμπλεγμάτων από αλυκές, ανάδειξη των ιστορικών λατομείων της περιοχής.)
-Η διεύρυνση του ορίζοντα στις οπτικές που υποβάλλονται από το παρελθόν
(η θέα προς τη χερσόνησο Τηγάνι, η σχέση του Κάστρου Μαΐνη με την ενότητα
λατομείων κατά μήκος ενός ξεροχείμαρρου)

description: We take account of normal currents that emerge when vortices move. Moving Abrikosov vortices in the bulk and Pearl vortices in thin films are considered. Velocity dependent distributions of both normal and persistent currents are studied in the frame of time-dependent London equations. In thin films near the Pearl vortex core, these distributions are intriguing in particular.

description: Within the framework of the homogeneous non-linear Boltzmann equation, we present a new analytic method, without the intrinsic limitations of existing methods, for obtaining asymptotic solutions. This method permits extension of existing results for Maxwell molecules and hard spheres to large classes of particle interactions, from very hard spheres to softer than Maxwell molecules, as well as to more general forcing mechanisms, beyond free cooling and white noise driving. By combining this method with numerical solutions, obtained from the Direct Simulation Monte Carlo (DSMC) method, we study a broad class of models relevant for the dynamics of dissipative fluids, including granular gases. We establish a criterion connecting the stability of the non-equilibrium steady state to an exponentially bound form for the velocity distribution $F$, which varies depending on the forcing mechanism. Power laws arise in marginal stability cases, of which several new cases are reported. Our results provide a minimal framework for interpreting large classes of experiments on driven granular gases.
BVI Photometry and the Luminosity Function of the Globular Cluster M92

description: We present new BVI ground-based photometry and VI space-based photometry for the globular cluster M92 (NGC 6341) and examine luminosity functions in B, V, and I containing over 50,000 stars ranging from the tip of the red giant branch to several magnitudes below the main sequence turn off. Once corrected for completeness, the observed luminosity functions agree very well with theoretical models and do not show stellar excesses in any region of the luminosity function. Using reduced chi squared fitting, the new M92 luminosity function is shown to be an excellent match to the previously published luminosity function for M30. These points combine to establish that the "subgiant excess" found in previously published luminosity functions of Galactic globular clusters are due to deficiencies in the stellar models used at that time. Using up to date stellar models results in good agreement between observations and theory. Several statistical methods are presented to best determine the age of M92. These methods prove to be insensitive to the exact choice of metallicity within the published range. Using [Fe/H]=-2.17 to match recent studies we find an age of 14.2 plus or minus 1.2 Gyr for the cluster.

description: We present the first high-resolution spectroscopic study of LiCs. LiCs is formed in a heat pipe oven and studied via laser-induced fluorescence Fourier-transform spectroscopy. By exciting molecules through the X$^1Σ^+$-B$^1Π$ and X$^1Σ^+$-D$^1Π$ transitions vibrational levels of the X$^1Σ^+$ ground state have been observed up to 3cm^{-1} below the dissociation limit enabling an accurate construction of the potential. Furthermore, rovibrational levels in the a$^3Σ^+$ triplet ground state have been observed because the excited states obtain sufficient triplet character at the corresponding excited atomic asymptote. With the help of coupled channels calculations accurate singlet and triplet ground state potentials were derived reaching the atomic ground state asymptote and allowing first predictions of cold collision properties of Li + Cs pairs.

description: We consider the minimization of the number of non-zero coefficients (the $\ell_0$ "norm") of the representation of a data set in terms of a dictionary under a fidelity constraint. (Both the dictionary and the norm defining the constraint are arbitrary.) This (nonconvex) optimization problem naturally leads to the sparsest representations, compared with other functionals instead of the $\ell_0$ "norm". Our goal is to measure the sets of data yielding a $K$-sparse solution--i.e. involving $K$ non-zero components. Data are assumed uniformly distributed on a domain defined by any norm--to be chosen by the user. A precise description of these sets of data is given and relevant bounds on the Lebesgue measure of these sets are derived. They naturally lead to bound the probability of getting a $K$-sparse solution. We also express the expectation of the number of non-zero components. We further specify these results in the case of the Euclidean norm, the dictionary being arbitrary.

description: We use two stellar populations in the globular cluster 47 Tucanae to trace its dynamical history: blue stragglers and low mass main sequence stars. We assumed that the blue stragglers were formed through stellar collisions in all regions of the cluster. We find that in the core of the cluster, models of collisional blue stragglers agree well with the observations as long as blue stragglers are still continuing to form and the mass function in the cluster is extremely biased towards massive stars (x=-8 where a Salpeter mass function has x=+1.35). We show that such an extreme mass function is supported by direct measurements of the luminosity function of main sequence stars in the centre of the cluster. In the middle region of our dataset (25'' to 130'' from the cluster centre), blue straggler formation seems to have stopped about half a Gyr ago. In the outskirts of the cluster, our models are least successful at reproducing the blue straggler data. Taken at face value, they indicate that blue straggler formation has been insignificant over the past billion years, and that a Salpeter mass function applies. However, it is more likely that the dominant formation mechanism in this part of the cluster is not the collisional one, and that our models are not appropriate for this region of the cluster. We conclude that blue stragglers can be used as tracers of dynamics in globular clusters, despite our incomplete understanding of how and where they were formed.

description: Recent improvements in the modeling of solar convection and line formation led to downward revisions of the solar photospheric abundances of the lighter elements, which in turn led to changes in the radiative opacity of the solar interior and hence to conflicts with the solar convection zone depth as inferred from helioseismic oscillation frequencies. An increase of the solar Ne/O abundance to values as observed for nearby stars has been proposed as a solution. Because of the absence of strong neon lines in the optical, neon abundances are difficult to measure and the correct solar and stellar Ne/O abundances are currently hotly debated. Based on X-ray spectra obtained with XMM-Newton, we determine a reference value of Ne/O for the inactive, solar-like star alpha Cen (primarily alpha Cen B, which is the dominant component in X-rays), with three independent, line-based methods, using differential emission measure reconstruction and an emission measure-independent method. Our results indicate a value of approx. 0.28 for Ne/O in alpha Cen, approximately twice the value measured for the Sun, but still below the average value obtained for other stars. The low Ne/O abundance of the Sun is peculiar when compared to alpha Cen and other stars; our results emphasize the necessity to obtain more and accurate Ne/O abundance measurements of low activity stars.

description: Motivated by the disagreement found at high dissipation between simulation data for the heat flux transport coefficients and the expressions derived from the Boltzmann equation by the standard first Sonine approximation [Brey et al., Phys. Rev. E 70, 051301 (2004); J. Phys.: Condens. Matter 17, S2489 (2005)], we implement in this paper a modified version of the first Sonine approximation in which the Maxwell-Boltzmann weight function is replaced by the homogeneous cooling state distribution. The structure of the transport coefficients is common in both approximations, the distinction appearing in the coefficient of the fourth cumulant $a_2$. Comparison with computer simulations shows that the modified approximation significantly improves the estimates for the heat flux transport coefficients at strong dissipation. In addition, the slight discrepancies between simulation and the standard first Sonine estimates for the shear viscosity and the self-diffusion coefficient are also partially corrected by the modified approximation. Finally, the extension of the modified first Sonine approximation to the transport coefficients of the Enskog kinetic theory is presented.

Framing urban shrinkage in policy and planning responses - examples from the European Union
Creators: name: Ivanov, Bozhidar
Publisher: name: Zenodo
Year: 2021

description: Urban shrinkage represents a constellation of ongoing changes that manifest with different severity in cities and regions. With effects on urban fabric, economic development and social factors, scientists have long attempted to ‘diagnose’ shrinkage in a robust way. Yet, when looking from the perspective of policy making and planning, understanding shrinkage remains difficult and so do the responses to it. European cities and regions have been experiencing shrinkage and the consequences of population decline for a long time. Some of those responses have prompted discussions for the possibility to identify new planning approaches to dealing with shrinkage. To what extent, however, have those responses been guided by a unifying idea, a planning concept? How has shrinkage been framed in policy and planning approaches in different contexts in the European Union and how has this interpretation affected the approaches to it?
 Applying interpretive policy analysis as a discourse analytical technique to policy and planning efforts from the Netherlands, Germany and Spain, this presentation outlines the interdependencies between the effects of shrinkage on urban and regional scale and the solutions that have been identified in the respective cases. By introducing a post-positivist approach to the question of handling urban shrinkage, the preliminary results of this ongoing research outline the conceptual heterogeneity of shrinkage as a challenge for policy and planning. Further reflection on this framing enables the identification of possible future approaches to urban shrinkage, potentially in the form of a new planning concept under the label of “Shrinking Smart”.

description: We study how geometrical and topological aspects of certain 1/2 BPS type IIB supergravity solutions are captured by the N=4 Super Yang-Mills gauge theory in the AdS/CFT context. The type IIB solutions are completely characterized by arbitrary droplets in a plane and we consider, in particular, concentric droplets. We probe the dual 1/2 BPS operators of the gauge theory with single traces and extract their one-loop anomalous dimensions. The action of the one-loop dilatation operator can be reformulated as the Hamiltonian of a bosonic lattice. The operators defining the Hamiltonian encode the topology of the droplet. The axial symmetry of the droplets turns out to be essential for obtaining the spectrum of the Hamiltonians. In appropriate BMN limits, the near-BPS spectrum reproduces the spectrum of near-BPS string excitations propagating along each individual edge of the droplet of the dual geometric background. We also study semiclassical regimes for the Hamiltonians. We show that for droplets having disconnected constituents, the Hamiltonian admits different complimentary semiclassical descriptions, each one replicating the semiclassical description for closed strings extending in each of the constituents.

On the number of contacts of a floating polymer chain cross-linked with a surface adsorbed chain on fractal structures

description: We study the interaction problem of a linear polymer chain, floating in fractal containers that belong to the three-dimensional Sierpinski gasket (3D SG) family of fractals, with a surface-adsorbed linear polymer chain. Each member of the 3D SG fractal family has a fractal impenetrable 2D adsorbing surface, which appears to be 2D SG fractal. The two-polymer system is modelled by two mutually crossing self-avoiding walks. By applying the Monte Carlo Renormalization Group (MCRG) method, we calculate the critical exponents $ϕ$, associated with the number of contacts of the 3D SG floating polymer chain, and the 2D SG adsorbed polymer chain, for a sequence of SG fractals with $2\le b\le 40$. Besides, we propose the codimension additivity (CA) argument formula for $ϕ$, and compare its predictions with our reliable set of the MCRG data. We find that $ϕ$ monotonically decreases with increasing $b$, that is, with increase of the container fractal dimension. Finally, we discuss the relations between different contact exponents, and analyze their possible behaviour in the fractal-to-Euclidean crossover region $b\to\infty$.

description: Allosteric regulation is often viewed as thermodynamic in nature. However protein internal motions during an enzymatic reaction cycle can be slow hopping processes over numerous potential barriers. We propose that regulating molecules may function by modifying the nonequilibrium protein dynamics. The theory predicts that an enzyme under the new mechanism has different temperature dependence, waiting time distribution of the turnover cycle, and dynamic fluctuation patterns with and without effector. Experimental tests of the theory are proposed.

description: The Mixture Transition Distribution (MTD) model was introduced by Raftery to face the need for parsimony in the modeling of high-order Markov chains in discrete time. The particularity of this model comes from the fact that the effect of each lag upon the present is considered separately and additively, so that the number of parameters required is drastically reduced. However, the efficiency for the MTD parameter estimations proposed up to date still remains problematic on account of the large number of constraints on the parameters. In this paper, an iterative procedure, commonly known as Expectation-Maximization (EM) algorithm, is developed cooperating with the principle of Maximum Likelihood Estimation (MLE) to estimate the MTD parameters. Some applications of modeling MTD show the proposed EM algorithm is easier to be used than the algorithm developed by Berchtold. Moreover, the EM Estimations of parameters for high-order MTD models led on DNA sequences outperform the corresponding fully parametrized Markov chain in terms of Bayesian Information Criterion. A software implementation of our algorithm is available in the library seq++ at http://stat.genopole.cnrs.fr/seqpp

description: We present the latest results of a long-term observational project aimed at observing, collecting from the literature, and homogenising the light, colour, and spectral variations of the well-known emission-line Be star V923 Aql. Our analysis of these parameters confirms that all of the observables exhibit cyclic changes with variable cycle length between about 1800 and 3000 days, so far documented for seven consecutive cycles. We show that these variations can be qualitatively understood within the framework of the model of one-armed oscillation of the circumstellar disk, with a wave of increased density and prograde revolution in space. We confirm the binary nature of the object with a 214.716 day period and estimate the probable system properties. We also confirm the presence of rapid light, and likely also spectral changes. However, we cannot provide any firm conclusions regarding their nature. A quantitative modelling study of long-term changes is planned as a follow-up to this work.

Paddle to Seattle : a native Washington movement to "Bring them canoes back home"
Creators: name: Lincoln, Leslie Jeanne
Publisher: name: University of British Columbia
Year: 2012

description: This thesis documents the 1989 Washington Centennial Commissions' Native Canoe Project. Seventeen Western Washington tribes participated in a canoe-oriented cultural heritage renewal movement. The ethnographic setting establishes Native dugouts in their historic social context and presents the classic hull forms of representative canoe types. After a hiatus of several generations of canoe use, many tribes began to reconstruct their disappearing canoeing ways. Through the process of carving and using their dugouts, they have addressed current issues. Canoe racing and voyaging has proven to be effective, culturally relevant alternative to drug and alcohol abuse. Native people reaffirmed access to landing beaches and forest resources and created community carving centers. Case studies of the Lummi, Suquamish, Tulalip, Port Gamble Klallam and Quileute tribes reveal continuity, schisms and the reinvention of Native dugout traditions. The culminating "Paddle to Seattle" voyage illuminates the vital role of these canoes to unite communities and legitimize Indian values. Abundant use of Native commentary from collected oral histories substantiate my interpretations and offer authority to Native perspectives. Ethnopoetic transcriptions express an understanding of these cedar canoes in the enduring Native thoughtworld.

description: We compute the fragmentation functions for the production of a Higgs boson at $\mathcal{O}(y_t^2α_s)$. As part of this calculation, the relevant splitting functions are also derived at the same perturbative order. Our results can be used to compute differential cross sections with arbitrary top-quark and Higgs-boson masses from massless calculations. They can also be used to resum logarithms of the form $\ln(p_T/m)$ at large transverse momentum $p_T$ to next-to-leading-logarithmic accuracy by solving the DGLAP equations.

description: There are many methods for projecting spherical maps onto the plane. Interactive versions of these projections allow the user to centre the region of interest. However, the effects of such interaction have not previously been evaluated. In a study with 120 participants we find interaction provides significantly more accurate area, direction and distance estimation in such projections. The surface of 3D sphere and torus topologies provides a continuous surface for uninterrupted network layout. But how best to project spherical network layouts to 2D screens has not been studied, nor have such spherical network projections been compared to torus projections. Using the most successful interactive sphere projections from our first study, we compare spherical, standard and toroidal layouts of networks for cluster and path following tasks with 96 participants, finding benefits for both spherical and toroidal layouts over standard network layouts in terms of accuracy for cluster understanding tasks.

description: Purpose: The application of Cox Proportional Hazards (CoxPH) models to survival data and the derivation of Hazard Ratio (HR) is well established. While nonlinear, tree-based Machine Learning (ML) models have been developed and applied to the survival analysis, no methodology exists for computing HRs associated with explanatory variables from such models. We describe a novel way to compute HRs from tree-based ML models using the Shapley additive explanation (SHAP) values, which is a locally accurate and consistent methodology to quantify explanatory variables' contribution to predictions. Methods: We used three sets of publicly available survival data consisting of patients with colon, breast or pan cancer and compared the performance of CoxPH to the state-of-art ML model, XGBoost. To compute the HR for explanatory variables from the XGBoost model, the SHAP values were exponentiated and the ratio of the means over the two subgroups calculated. The confidence interval was computed via bootstrapping the training data and generating the ML model 1000 times. Across the three data sets, we systematically compared HRs for all explanatory variables. Open-source libraries in Python and R were used in the analyses. Results: For the colon and breast cancer data sets, the performance of CoxPH and XGBoost were comparable and we showed good consistency in the computed HRs. In the pan-cancer dataset, we showed agreement in most variables but also an opposite finding in two of the explanatory variables between the CoxPH and XGBoost result. Subsequent Kaplan-Meier plots supported the finding of the XGBoost model. Conclusion: Enabling the derivation of HR from ML models can help to improve the identification of risk factors from complex survival datasets and enhance the prediction of clinical trial outcomes.

description: A boundary layer interacting with a cavity is a benchmark case that is present in environmental applications, aeronautics, automobile aerodynamics or industrial applications, where the velocity over a rectangular cavity is relatively low. In the present investigation, the interaction between a laminar boundary layer with external velocity Ue and an open cavity is investigated experimentally for medium range Reynolds numbers (between 4600 and 18500) with flow diagnostics optical methods, for a cavity aspect ratio (length over depth) of two. A shear layer induces a main vortex and a counter-rotating secondary vortex inside the cavity. The shear layer also develops instabilities interacting with the downstream cavity edge. Particle image velocimetry (PIV) and laser Doppler velocimetry (LDV) measurements are synchronized in order to get global information of both spatial velocity fields and time-resolved signals in a particular position situated downstream of the development of the shear layer above the cavity. The PIV velocity fields are phase-averaged with a singular value decomposition of the LDV signal.

Optimal harvest policies in salmon gauntlet fisheries : terminal versus mixed stock fishery harvest
Creators: name: Luedke, Wilfred Harold
Publisher: name: University of British Columbia
Year: 2012

description: A case study of the chum salmon (Oncorhynchus keta) gauntlet fisheries in Southern British Columbia is described. Acrimony between industry and government managers has been commonplace in the management of this fishery. In an attempt to alleviate this acrimony, a management system call the "clockwork" has been implemented, which provides all fishermen an opportunity for greater understanding of the management rationale and greater input into the decision-making process. The clockwork has been generally successful; the stocks are rebuilding and the fishermen are involved in the management of the fishery. However, two problems are identified in the clockwork. First, the success of the clockwork in alleviating the aaimony associated with the chum fishery depends on the ability of fishery managers to provide sound and scientifically defensible in-season stock assessments. If the assessments have no better track record than the intuition of managers and fishermen then the clockwork will not be successful. Second, there is a nagging problem of allocation of harvests between the mixed stock fishery in Johnstone Strait and the terminal fishery in the Fraser River. The main factor is the difference in price behveen the two fisheries; the price in the terminal fishery is only about one-third of the price paid in the mixed stock fishery, Dynamic programming techniques are used to determine the optimal harvest strategies for this gauntlet fishery. Generally, the optimal strategy is similar to a fixed escapement strategy when both stocks are equally abundant. But when one stock is much more abundant the optimal strategy is to harvest harder in the mixed stock fishery. With the current difference in value per fish between the two fisheries, the optimal exploitation rates in the terminal area are zero, all the catch is taken in the mixed stock fishery. The minimum price at which terminal fisheries provide long term economic benefit is the threshold price. For the parameters used to describe the current fishery, the threshold price is approximately 40% of the mixed stock fishery price. Furthermore, the threshold price differs with stock recruitment parameters, especially stock productivity and recruitment variability. Generally the more similar the stocks are, with respect to stock and recruitment characteristics, the lower the threshold value for fishing in the terminal areas. The results provide a basis for discussion of the utility of terminal fisheries, and by adjusting the relative value of the terminal fishery in relation to the mixed stock fishery can incorporate additional social and aesthetic values, as well as costs such as harvesting costs and fisheries management costs.

description: Most existing proposals about anaphoric zero pronoun (AZP) resolution regard full mention coreference and AZP resolution as two independent tasks, even though the two tasks are clearly related. The main issues that need tackling to develop a joint model for zero and non-zero mentions are the difference between the two types of arguments (zero pronouns, being null, provide no nominal information) and the lack of annotated datasets of a suitable size in which both types of arguments are annotated for languages other than Chinese and Japanese. In this paper, we introduce two architectures for jointly resolving AZPs and non-AZPs, and evaluate them on Arabic, a language for which, as far as we know, there has been no prior work on joint resolution. Doing this also required creating a new version of the Arabic subset of the standard coreference resolution dataset used for the CoNLL-2012 shared task (Pradhan et al.,2012) in which both zeros and non-zeros are included in a single dataset.

description: The quantum approximate optimization algorithm (QAOA) has become a cornerstone of contemporary quantum applications development. In QAOA, a quantum circuit is trained -- by repeatedly adjusting circuit parameters -- to solve a problem. Several recent findings have reported parameter concentration effects in QAOA and their presence has become one of folklore: while empirically observed, the concentrations have not been defined and analytical approaches remain scarce, focusing on limiting system and not considering parameter scaling as system size increases. We found that optimal QAOA circuit parameters concentrate as an inverse polynomial in the problem size, providing an optimistic result for improving circuit training. Our results are analytically demonstrated for variational state preparations at $p=1,2$ (corresponding to 2 and 4 tunable parameters respectively). The technique is also applicable for higher depths and the concentration effect is cross verified numerically. Parameter concentrations allow for training on a fraction $w < n$ of qubits to assert that these parameters are nearly optimal on $n$ qubits. Clearly this effect has significant practical importance.

The American political discourse on the Cuban missile crisis
Creators: name: Guttieri, Karen Rochelle
Publisher: name: University of British Columbia
Year: 2012

description: This thesis examines and critiques the American political discourse on the Cuban missile crisis of 1962. The event itself is past, yet words used to describe and explain the missile crisis capture and give meaning to the experience. The meaning of the crisis begins in a basic sense, then, with the discourse. The increasing availability of material evidence has reinvigorated the discourse on the missive crisis. Where relevant, recent evidence will be employed to critique previous and recent interpretations of the this seminal event. Consensus and debate are both to be found in the discourse on the Cuban crisis. First, there is a large body of shared understanding, or conventional wisdom, on the crisis. Secondly, there is disagreement as to the meaning of the crisis in recent manifestations of the discourse. The essay will use a propaganda model lo examine the politically necessary mythology embodied in the conventional wisdom. This thesis will use a tendency analysis approach to organize the debate on the missile crisis, along the lines of ideological schools of thought, and within the context of a larger American nuclear debate. The propaganda and the tendency analyse models complement the general approach of discourse. These models have been developed specifically for the study of politics, yet the methodology of each is statement analysis; as such these models are rooted in language, ana so conform with the general discourse approach. Security is the common referent of both the conventional wisdom and the current debate. In particular, the President, as the custodian of nuclear weapons, is the principle actor responsible for national security. The powerful image of the President dominates the conventional wisdom, and retains significance in the contemporary ideological debate on the lessons of the missile crisis. The nuclear arsenal at the disposal of the President endows him with great, but double-edged power. The paper concludes with some general observations on the special significance of Presidential leadership as represented in the discourse on the missile crisis, and as necessitated in confronting crises in general. First, in crisis, there is little time for the President to make difficult decisions. Secondly, there may be greater devolution of authority to the military forces deployed to convey the credibility of American deterrence. As such, the subordination of force to policy must remain sound. The image of the President is, of necessity, an image which combines prudence and strength. Manufactured images are not enough however. Policy must be tested in terms of its alleged purpose. Likewise, doctrine must be evaluated in terms the purpose of the policy it is designed to support.
