description: We find that institutional ownership in publicly traded companies is associated with more innovation (measured by cite-weighted patents). To explore the mechanism through which this link arises, we build a model that nests the lazy-manager hypothesis with career-concerns, where institutional owners increase managerial incentives to innovate by reducing the career risk of risky projects. The data supports the career concerns model. First, whereas the lazy manager hypothesis predicts a substitution effect between institutional ownership and product market competition (and managerial entrenchment generally), the career-concern model allows for complementarity. Empirically, we reject substitution effects. Second, CEOs are less likely to be fired in the face of profit downturns when institutional ownership is higher. Finally, using instrumental variables, policy changes and disaggregating by type of owner we find that the effect of institutions on innovation does not appear to be due to endogenous selection.

description: Studies have concluded that active debris removal (ADR) of the existing in-orbit mass is necessary. However, the quest for an optimal solution does not have a unique answer and the available data often lacks coherence. To improve this situation, modern knowledge representation techniques, that have been shaping the World Wide Web, medicine and pharmacy, should be employed. Prior efforts in the domain of space debris have only focused onto space situational awareness, neglecting ADR. To bridge this gap we present a domain-ontology of intact derelict objects, i.e. payloads and rocket bodies, for ADR capture methods selection. The ontology is defined on a minimal set of physical, dynamical and statistical parameters of a target object. The practicality and validity of the ontology are demonstrated by applying it onto a database of 30 representative objects, built by combining structured and unstructured data from publicly available sources. The analysis of results proves the ontology capable of inferring the most suited ADR capture methods for considered objects. Furthermore, it confirms its ability to handle the input data from different sources transparently, minimizing user input. The developed ontology provides an initial step towards a more comprehensive knowledge representation framework meant to improve data management and knowledge discovery in the domain of space debris. Furthermore, it provides a tool that should make the initial planning of future ADR missions simpler yet more systematic.

title: Sharp force trauma to bone: The effect of soil on cut marks made using replica archaeological swords
Creators: name: Burrows, Elissia Patara
Publisher: name: University of Kent
Year: 2024

description: Analysis of cut marks made by archaeological weaponry is currently very limited, due to the focus of 
study being on forensic applications with modern sharp force implements, especially when it comes to analysis of any changes that can be made to the cut marks by the burial environment. The current study aims to bridge the gap between forensic and archaeological cut mark analysis and produce
criteria to not only distinguish between cut marks made by archaeological swords, but also to determine what changes can occur to the cut marks during the burial period. A handheld Dino-Lite digital microscope was employed to examine cut marks made on defleshed porcine bone. A total of 252 cut marks were made by three replica archaeological swords: a long sword (n= 91), gladius Pompeii (n= 89) and seax (n= 86). The cut marks were further broken down into their bone type: femur (n= 140) and tibia (n= 126) and location of the cut mark on the bone: proximal (n= 35), proximal shaft (n= 35), distal shaft (n= 33) and distal (n= 25). The distinction between bone type and cut mark location was provided so that the effect of bone morphology on the cut marks could also be analysed. Half of the cut mark sample were then buried for a period of 16 months, so that comparisons could be made between the same cut marks, both before and after the burial period (post burial cutmarks n= 129).
The results suggested that current criteria for distinguishing sword cut marks is not entirely applicable to cut marks that have been exposed to a burial environment. Cut mark features were seen to alter or be removed after burial, which is significant for current forensic and archaeological applications, as these changes can alter the ease of identification of the weapon which caused the cut mark. This finding indicates that further research into the effects of the burial environment upon a cut mark is still needed, to explore the numerous variables involved. Additionally, it was found that the specific location on the bone where the cut mark was made can produce varying features. If the same weapon can cause differing cut mark morphology on the same bone element, then this is important for refining the criteria for sword cut mark identification.
It is suggested from the results that, where cross profiles and cut marks are clear from damage, post excavation processes (i.e., ink and glue) and obscured views, the DinoLite microscope is an effective, accurate and low-cost alternative tool for cutmark analysis.
Individuals’ with heart failure experiences of collaboration with the health care team : an interpretive description
Creators: name: Werry, Terina
Publisher: name: University of British Columbia
Year: 2009

description: I designed this study to explore the experience of collaboration from the perspective of people with heart failure (HF) attending a heart function clinic (HFC). There is a paucity of literature explicating the experience of collaboration from the perspective of the individual with HF, although the literature provides strong support for the benefits of collaboration for people with HF. My intent was to increase the knowledge and understanding of the experience of collaboration for individuals with HF to inform nursing practice, education, and research. The qualitative research approach, interpretive description, as described by Thorne, Reimer Kirkham, and Macdonald Emes (1997) was utilized as my research method, as it was appropriate to answering my research question, "how do individuals with HF experience collaboration with the health care team in the setting of an outpatient HFC?" Data were collected utilizing in-depth semi-structured interviews, with a total of 7 participants ranging in age from 52 to 81 years. All of the participants had been attending a HFC for at least 2 years, with a mean attendance of 3.4 years. Inductive data analysis was ongoing throughout the data collection process. The findings informed and guided the data collection process and allowed the construction of the interpretive description. The narratives revealed five dominant themes describing the participants' experiences of collaboration with the health care team. These were mutual goals, working together, communication with the health care team, being accountable, and sharing power. Antecedents to the experience of collaboration included non-intimidating communication style and trust in the health care team. Barriers to the experience of collaboration identified were lack of time, communication styles that do not support collaboration and inequity of power sharing. The findings of this study may contribute to the theoretical understanding of the concept of collaboration, and has provided insight into the experience of collaboration as experienced by individuals with HF who attend a HFC. Thus this contribution to the existing knowledge about the experience of collaboration from the individual with HF may provide additional insight into and expand the understanding of the experience and thereby enhance the care of similar individuals.

description: We develop a dynamic model to analyze the sources and the evolution of social participation and social capital in a growing economy characterized by exogenous technical progress. Starting from the assumption that the well-being of agents basically depends on material and relational goods, we show that the best-case scenarios hold when technology and social capital both support just one of the two productions at the expenses of the other. However, trajectories are possible where technology and social interaction balance one another in fostering the growth of both the social and the private sector of the economy. Along such tracks, technology may play a crucial role in supporting a “socially sustainable” economic growth.

description: The extent of a locally equilibrated parton plasma in d + Au collisions at sqrt(s_NN) = 200 GeV is investigated as a function of collision centrality in a nonequilibrium-statistical framework. Based on a three-sources model, analytical solutions of a relativistic diffusion equation are in precise agreement with recent data for charged-particle pseudorapidity distributions. The moving midrapidity source indicates the size of the local thermal equilibrium region after hadronization. In central d + Au collisions it contains about 19% of the produced particles, and its relative importance rises with decreasing centrality.

description: (ABRIDGED) We analyze the X-ray properties of a sample of local and high redshift galaxy clusters extracted from a large cosmological hydrodynamical simulation. This simulation has been realized using the Tree+SPH code GADGET-2 for a LambdaCDM model. In our analysis, we consider only objects with T_ew >2 keV and adopt an approach that mimics observations, associating with each measurement an error comparable with recent observations and providing best-fit results via robust techniques. Within the clusters, baryons are distributed among (i) a cold neutral phase, with a relative contribution that increases from less than 1 to 3 per cent at higher redshift, (ii) stars which contribute with about 20 per cent and (iii) the X-ray emitting plasma that contributes by 80 (76) per cent at z=0 (1) to the total baryonic budget. A depletion of the cosmic baryon fraction of ~7 (at z=0) and 5 (at z=1) per cent is measured at the virial radius, R_vir, in good agreement with adiabatic hydrodynamical simulations. We confirm that, also at redshift >0.5, power-law relations hold between gas temperature, T, bolometric luminosity, L, central entropy, S, gas mass, M_gas, and total gravitating mass, M_tot and that these relations are steeper than predicted by simple gravitational collapse. A significant, negative evolution in the L-T and L-M_tot relations and positive evolution in the S-T relation are detected at 0.5 < z < 1 in this set of simulated galaxy clusters. This is partially consistent with recent analyses of the observed properties of z>0.5 X-ray galaxy clusters. By fixing the slope to the values predicted by simple gravitational collapse, we measure at high redshift normalizations lower by 10-40 per cent in the L-T, M_tot-T, M_gas-T, f_gas-T and L-M_tot relations than the observed estimates.

description: LAS (Localised Agri-food Systems) approach has been viewed until now as either an analysis of a variety of local production system or an anthropological vision of the links between food and places. Although theses approaches are relevant, they prove sometimes hard to differentiate themselves of close concepts such as Local production systems. This paper intends to assess in what measure LAS approach can be redefined as an approach of rural development processes, which could be the basis of a rural development policy. If LAS's are to be considered as the basis of a rural development path, LAS approach must be cast in the current debate on diversification of rural activities. Drawing on that, LAS can be the basis of a rural development policy, but only fit to some places, with a very specific “residential” relationship with the overall economic environment.

Using a Bekenstein argument the condition for the superradiance modes is shown to be $0 < ω< m Ω$ for the scalar, electromagnetic and gravitational waves when the spacetime background has a single angular momentum parameter about an axis on the brane, where $Ω$ is a rotational frequency of the black hole and $m$ is an azimuthal quantum number of the radiated wave.

This subject is important because it may provide information about the degree of entrepreneurship of the involved firms.
The Higgs Potential in 2HDM extended with a Real Triplet Scalar: A roadmap

description: We perform a comprehensive study of The Higgs potential of the two Higgs doublet model extended by a real triplet scalar field $Δ$. This model, dubbed $2\mathcal{HDM+T}$, has a rich Higgs spectrum consisting of three CP-even Higgs $h_{1,2,3}$, one CP-odd $A_0$ and two pairs of charged Higgs $H^\pm_{1,2}$. First, we determine the perturbative unitarity constraints and a set of non trivial conditions for the boundedness from below (BFB). Then we derive the Veltman conditions by considering the quadratic divergencies of Higgs boson self energies in $2\mathcal{HDM+T}$. We find that the parameter space is severely delimited by these theoretical constraints, as well as experimental exclusion limits and Higgs signal rate measurements at LEP and LHC. Using HiggsBounds-5.3.2beta and HiggSignals-2.2.3beta public codes an exclusion test at $2σ$ is then performed on the physical scalars of $2\mathcal{HDM+T}$. Our analysis provides a clear insight on the nonstandard scalar masses, showing that the allowed ranges are strongly sensitive to the sign of mixing angle $α_1$, essentially when naturalness is involved. For $α_1 < 0$ scenario, our results place higher limits on the bounds of all scalar masses, and show that the pairs $(h_2, H_1^\pm)$ and $(h_3, H_2^\pm)$ are nearly mass degenerate varying within the intervals $[130\,,\,246]$~GeV and $[160\,,\,335]$~GeV respectively. When $α_1$ turns positive, we show that consistency with theoretical constraints and current LHC data, essentially on the diphoton decay channel, favors Higgs masses varying within wide allowed ranges: $[153\,,\,973]$~GeV for $m_{A_0}$; $[151\,,\,928]$~GeV for ($m_{h_2}$, $m_{H_1^\pm}$) and $[186\,,\,979]$~GeV for ($m_{h_3}$, $m_{H_2^\pm}$). Finally, we find that the $γγ$ and $Zγ$ Higgs decay modes are generally correlated.

Culture and savoring of positive experiences
Creators: name: Lindberg, Tracy L.
Publisher: name: University of British Columbia
Year: 2009

description: Savoring is the process by which people enhance, intensify, or prolong their affective reactions to positive events (Bryant, 1989). Drawing on recent research regarding cultural variation in affective norms and experience, I examined savoring and related constructs in Japanese, Asian North American and European North American respondents. As defined in previous research with American samples, the construct of savoring was found to generalize to East Asian samples, with equivalent factor structure and similar relations on measures of convergent and discriminant validity. As predicted, East Asian respondents endorsed lower capacity for anticipating, savoring in the moment and reminiscing. Mediation analyses suggested that attitudes regarding the importance of enhancing positive feelings and beliefs about change played a role in mediating the relation between culture and savoring, but self-construal did not. In self-nominated positive events, East Asian individuals included more interpersonal and achievement events and made reference to positive events from the distant past or anticipated future in addition to current events. In contrast, European North Americans nominated more leisure events, and were temporally oriented to the present and recent past. Predictions with respect to cultural differences in savoring strategies were generally supported, with European North Americans endorsing more Self-Congratulation, Behavioral Expression and Sensory Perceptual Sharpening both in self-nominations and ratings on the Ways of Savoring Checklist (WOSC). Although the majority of strategies nominated across cultures were captured by the WOSC strategies of Sharing and Memory Building, several novel savoring strategies were reported by East Asian respondents, including Making Greater Effort and Continuing Connection with Others Involved. These results are generally consistent with other research finding both elements of universality and cultural variation in the experience of positive feelings.

description: We present a random matrix interpretation of the distribution functions which have appeared in the study of the one-dimensional polynuclear growth (PNG) model with external sources. It is shown that the distribution, GOE$^2$, which is defined as the square of the GOE Tracy-Widom distribution, can be obtained as the scaled largest eigenvalue distribution of a special case of a random matrix model with a deterministic source, which have been studied in a different context previously. Compared to the original interpretation of the GOE$^2$ as ``the square of GOE'', ours has an advantage that it can also describe the transition from the GUE Tracy-Widom distribution to the GOE$^2$. We further demonstrate that our random matrix interpretation can be obtained naturally by noting the similarity of the topology between a certain non-colliding Brownian motion model and the multi-layer PNG model with an external source. This provides us with a multi-matrix model interpretation of the multi-point height distributions of the PNG model with an external source.

description: Farmers Markets (FMs) around the world are often considered as one key response to the less sustainable conventional food production systems. Despite the economic crisis, international studies show that the most important factor leading people to buy fresh products in these points of sale is the quality. In fact, consumers usually cite “better food quality”, “locally produced foods”, “higher social interaction” and “learning directly about the vendors and their food production practices”, as the principal motivations in buying in FM environment. In this paper the results of a survey carried out in several FMs and shops in Tuscany are presented. A sample of consumers were interviewed on-site using a structured questionnaire. The attitude of respondent towards FM was assessed using a test scale composed of 16 items referring to five different features of this form of distribution, supposed to be relevant in the consumer choice: quality of products, direct contact with farmers, convenience, environmental sustainability, and support for rural development processes. The high level of reliability of the attitude scale allowed its use in performing a cluster analysis of observed units. The cluster analysis allowed to identify two groups of consumers with different characteristics both in term of socio-economic descriptive variables and in term of attitudes and motivations towards FMs.

description: A Dirac bundle is a euclidean bundle over a riemannian manifold $M$ which is a compatible left $C\ell(M)$-module, together with a metric connection also compatible with the Clifford action in a natural way. We prove some vanishing theorems and introduce the twistor equation within this framework. In particular, we exhibit a characterization of solutions for this equation in terms of the Dirac operator $D$ and a suitable Weitzenböck-type curvature operator $\mathcal{R}$. Finally, we analyze the especial case of the Clifford bundle to prove existence of nontrivial solutions of the twistor equation on spheres.

description: Calorimetric and coalescence techniques have been employed to probe equilibration for hot nuclei produced in heavy ion collisions of 35 to 55 MeV/u projectiles with medium mass targets. Entrance channel mass asymmetries and energies were selected in order that very hot composite nuclei of similar mass and excitation would remain after early stage pre-equilibrium particle emission. Inter-comparison of the properties and de-excitation patterns for these different systems provides evidence for the production of hot nuclei with decay patterns relatively independent of the specific entrance channel.

description: The aim of this paper is to discuss the planning of regional Agri-food supply chain using an integrated database territorial information. The objective is to optimize the chain performance using alternative solutions. Evidences are obtained with a case study performed in FVG region applied to maize-crop. Firstly it is explored the chain network composed by farms, collection points and processing plants; then territorial, agronomic and climate information are integrated to simulate realistic production forecast model applied to maize crop. Finally a program from graph analysis is used to allocate the production through the chain. The economic performance is evaluated using the net revenues varying with the intensification of maize production and adoption of different organization solutions (independent and cooperative). Conclusions are that the chain performance is influenced by a combination of technology and organization decisions and the policy maker can use these results to orient their targets about regional planning.

description: The joint observation of the gravitational-wave and electromagnetic signal from the binary neutron-star merger GW170817 allowed for a new independent measurement of the Hubble constant $H_0$, albeit with an uncertainty of about 15\% at 1$σ$. Observations of similar sources with a network of future detectors will allow for more precise measurements of $H_0$. These, however, are currently largely limited by the intrinsic degeneracy between the luminosity distance and the inclination of the source in the gravitational-wave signal. We show that the higher-order modes in gravitational waves can be used to break this degeneracy in astrophysical parameter estimation in both the inspiral and post-merger phases of a neutron star merger. We show that for systems at distances similar to GW170817, this method enables percent-level measurements of $H_0$ with a single detection. This would permit the study of time variations and spatial anisotropies of $H_0$ with unprecedented precision. We investigate how different network configurations affect measurements of $H_0$, and discuss the implications in terms of science drivers for the proposed 2.5- and third-generation gravitational-wave detectors. Finally, we show that the precision of $H_0$ measured with these future observatories will be solely limited by redshift measurements of electromagnetic counterparts.

Engagement theory and target identity : an analysis of North Korean responses to contemporary inter-Korean engagement
Creators: name: Roberts, Liam
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents an analysis of engagement theory, as compared and contrasted with deterrence and compellence, as a tool for minimizing the risk of conflict with a dissatisfied power. Using the particular case study of inter-Korean engagement since the 2000 North-South Korea Summit, this analysis proceeds with a model of "active engagement" that attempts the socialization of new norms in the belligerent target, alleviation of negative cognitive biases, and reduction in the target's material domain of losses, while maintaining a strong deterrent against expansionism. This study proceeds from the perspective of the dissatisfied power (the engagement target) in effort to better understand what motivates either cooperative or uncooperative responses to engagement. Domains of losses are complex and dependent on what goods (economic, political, ideational) a target values most. This study details the particular goods that North Korean leadership values most highly and analyzes internal preference formations that complicate outside efforts to engage the regime. In studying the South Korean engagement project, this thesis finds that a combination of de-politicized economic and cultural engagement streams has had a strong impact on North Korean preference formation. Mindful of negative cognitive biases that skew target states' perspective of external "promises," this study also argues that South Korea has managed to advance its engagement agenda by presenting itself as an internal actor to the divided Korean nation, thus reducing threat perceptions and appealing to North Korean ideational and political priorities. This thesis concludes that a de-linked, state-based, active engagement process must precede institutionalized, regime-based cooperation. This initial phase may nevertheless see cooperation move intermittently. As engagement is a change-oriented strategy, target states will attempt to resist change in certain issue areas while accepting change in others. However, as resistant to change as the target regime may be, engagement forces targets down a path to engagement that is difficult to reverse. As both source and target develop interests in engagement, reforming an adversarial discourse, the prospects for increased cooperation increase. This is despite the risk that the target may attempt to counterbalance cooperation with belligerence in the short-term.

description: Classic statistical techniques (like the multi-dimensional likelihood and the Fisher discriminant method) together with Multi-layer Perceptron and Learning Vector Quantization Neural Networks have been systematically used in order to find the best sensitivity when searching for $ν_μ\to ν_τ$ oscillations. We discovered that for a general direct $ν_τ$ appearance search based on kinematic criteria: a) An optimal discrimination power is obtained using only three variables ($E_{visible}$, $P_{T}^{miss}$ and $ρ_{l}$) and their correlations. Increasing the number of variables (or combinations of variables) only increases the complexity of the problem, but does not result in a sensible change of the expected sensitivity. b) The multi-layer perceptron approach offers the best performance. As an example to assert numerically those points, we have considered the problem of $ν_τ$ appearance at the CNGS beam using a Liquid Argon TPC detector.

description: Spin pumping in a ferromagnet/nonferromagnet heterostructure is directly imaged with spatial resolution as well as element selectivity. The time-resolved detection in scanning transmission x-ray microscopy allows to directly probe the spatial extent of the ac spin polarization in Co-doped ZnO which is generated by spin pumping from an adjacent permalloy microstrip. Comparing the relative phases of the dynamic magnetization component of the two constituents is possible and found to be antiphase. The correlation between the distribution of the magnetic excitation in the permalloy and the Co-doped ZnO reveals that laterally there is no one-to-one correlation. The observed distribution is rather complex, but integrating over larger areas clearly demonstrates that the spin polarization in the nonferromagnet extends laterally beyond the region of the ferromagnetic microstrip. Therefore the observations are better explained by a local spin pumping efficieny and a lateral propagation of the ac spin polarization in the nonferromagnet over the range of a few micrometers.

On the photon-pseudoscalar particle mixing in media and external fields

description: In this work, I study the mixing of photons with pseudoscalar particles and vice-versa in the presence of an external magnetic field and a pseudoscalar field. I solve exactly for the first time in the literature the equations of motion of the electromagnetic field coupled with a pseudoscalar field in the presence of a constant magnetic field with arbitrary direction with respect to the direction of propagation of the fields in vacuum. In addition, I also solve exactly the equations of motion in a magnetized plasma/gas for perpendicular propagation with respect to the external magnetic field. By finding exact solutions to the equations of motion, I find exact expressions for the transition efficiencies of photons into pseudoscalar particles in different situations. The expressions of the transition efficiencies generalize and correct those previously found in the literature by using approximate WKB methods on solving the equations of motion. In the case when the direction of propagation of fields with respect to the external magnetic field is not perpendicular, a longitudinal state of the electromagnetic field is generated even in a magnetized vacuum. The appearance of the longitudinal electric field state could be used for laboratory searches of pseudoscalar particles such as the axion and/or axion-like particles.

Triggered massive-star formation on the borders of Galactic HII regions. I. A search for `collect and collapse' candidates

description: Young massive stars or clusters are often observed at the peripheries of HII regions. What triggers star formation at such locations? Among the scenarios that have been proposed, the `collect and collapse' process is particularly attractive because it permits the formation of massive objects via the fragmentation of the dense shocked layer of neutral gas surrounding the expanding ionized zone. However, until our recent article on Sh 104, it had not been convincingly demonstrated that this process actually takes place. In the present paper we present our selection of seventeen candidate regions for this process; all show high-luminosity near-IR clusters and/or mid-IR point sources at their peripheries. The reality of a `collect and collapse' origin of these presumably second-generation stars and clusters will be discussed in forthcoming papers, using new near-IR and millimetre observations.

description: Our purpose in the present work is to make a methodological contribution to enrich the SYAL concept from two points of view. Firstly, as a critical reconsideration of the theory of territorial development, and more specifically SYAL development, taking into account the fact that the local institutional framework is the result of the complex - even conflictive - interaction of economic rationales based on diverse cultural logics. Secondly, as an analysis of the strategies promoted by this type of development, identifying the endogenous components which strengthen and reinforce in local actors the ability to reflectively structure and re-structure system relationships at the territorial level. The empirical-ethnographic support for these reflections is drawn from two zones of Chile's southern coastline. The first, in the southern Aysen Region, illustrates the dilemmas and responses of local-traditional economies based on small-scale fishing in the face of the sustained growth of the captive salmon production mega-industry along a large part of the coastline. The second, in the neighbouring Los Lagos Region, reports on the strategies of traditional small-scale mussel-growers in the Reloncaví Estuary, in the context of the invasion of their economic space by multinational companies and the technification of their traditional systems.

description: Sampling from high dimensional distributions and volume approximation of convex bodies are fundamental operations that appear in optimization, finance, engineering, artificial intelligence and machine learning. In this paper we present volesti, an R package that provides efficient, scalable algorithms for volume estimation, uniform and Gaussian sampling from convex polytopes. volesti scales to hundreds of dimensions, handles efficiently three different types of polyhedra and provides non existing sampling routines to R. We demonstrate the power of volesti by solving several challenging problems using the R language.
