description: In direct gauge mediation, the gaugino masses are anomalously small, giving rise to a split SUSY spectrum. Here we investigate the superpartner spectrum in a minimal version of "direct gaugino mediation." We find that the sfermion masses are comparable to those of the gauginos - even in the hybrid gaugino-gauge mediation regime - if the messenger scale is sufficiently small.

Greenhouse gas emissions in mining operations : challenges and opportunities in British Columbia, Canada
Creators: name: Ballantyne, Sheila Marie
Publisher: name: University of British Columbia
Year: 2011

description: This research explores how the mining industry of British Columbia is currently managing greenhouse gases (GHG) and seeks to understand regulations designed to limit emissions. The objective is to recommend options and approaches for effective GHG management strategies for the mining industry of British Columbia. Three research approaches are utilised; a review on the current state of GHG policies and technical options, an assessment of how the mining industry is managing GHG issues using content analysis, and modelled scenarios to illustrate some of the influences on overall emissions from a typical mine in British Columbia. This research is initiated through a review on proposed GHG polices with influence on industry in British Columbia. This review also discusses recent trends in GHG and fossil fuel dependency. The options available to meet emissions reductions are outlined, including economic tools and technology adoption. This review is a platform from which the mining industry of British Columbia can move forward in effective GHG management. An analysis of documents published by mining firms operating in British Columbia reveals trends in their reporting of GHG related issues. The hypothesis posed is that while there are no reductions observed in GHG emissions, companies perceive an incentive to release qualitative information on the subject. The results of the analysis show an increase in qualitative reporting related to climate change since 2001, which may be in response to growing public awareness and impending governmental policies. Opportunities for GHG reductions for typical mines in British Columbia are explored using dynamic models. Systematic changes illustrate various scenarios of net emissions over time. It shows that small changes in transport and fuel types can cause significant reductions on mining emissions. This research recommends that mining firms become proactive in response to GHG emissions polices; delayed preparation may result in increased opportunity costs. It suggests operational decisions use predicted GHG prices in cost-benefit analyses. Action now will prepare the mining industry for impending regulations with the added potential benefits of reduced fuel costs and improving environmental performance.

description: We construct and probe a holographic description of state of matter which results from coupling a Fermi liquid to a relativistic conformal field theory (CFT). The bulk solution is described by a quantum gas of fermions supported from collapse into the gravitational well of AdS by their own electrostatic repulsion. In the probe limit studied here, the Landau quasiparticles survive this coupling to a CFT.

Holopyga amoenula Dahlbom 1845: 4. Lectotype ♂ (designated by Rosa in prep.); Greece: Rhodes Isl. (NRM) (examined) (Holopyga lucida group).
Remarks. Dahlbom (1954: 53) considered H. amoenula to be a variety (var. d) of the newly described species H. ovata (= H. generosa Förster), with no regard to the principle of priority, not yet applied at that time. Later Mocsáry (1889: 127) treated H. ovata as a junior synonym of H. amoenula and several authors erroneously followed his interpretation. From the Nordic and Baltic countries amoenula was reported either as a distinct species (Bischoff 1910: 440, Sahlberg 1910: 98 (as Elampus amoenus), Aurivillius 1911: 7, Tumšs 1976: 22) or as a variation of Holopyga gloriosa (Jansson 1922: 33, Jansson 1934: 287, Hellén 1935: 8, Fahlander 1954: 254). The name gloriosa has been suppressed by the Commission on the Iczn (ICZN 1998). Only after Linsenmaier's revision of the European species (1959), H. amoenula was correctly identified and recognized as a separated and valid taxon endemic to Rhodes Island.

description: The magneto-electric (ME) coupling on spin-wave resonances in single-crystal Cu2OSeO3 was studied by a novel technique using electron spin resonance combined with electric field modulation. An external electric field E induces a magnetic field component μ_0 H^i = γE along the applied magnetic field H with γ=0.7(1) μT/(V/mm) at 10 K. We found that ME coupling strength γis temperature dependent and highly anisotropic. γ(T) nearly follows that of spin susceptibility J(T) and rapidly decreases above the Curie temperature Tc. The ratio γ/J monotonically decreases with increasing temperature without an anomaly at Tc.

description: This paper considers a spin chain model by numerically solving the exact model to explore the non-perturbative dynamical decoupling regime, where an important issue arises recently (J. Jing, L.-A. Wu, J. Q. You and T. Yu, arXiv:1202.5056.). Our study has revealed a few universal features of non-perturbative dynamical control irrespective of the types of environments and system-environment couplings. We have shown that, for the spin chain model, there is a threshold and a large pulse parameter region where the effective dynamical control can be implemented, in contrast to the perturbative decoupling schemes where the permissible parameters are represented by a point or converge to a very small subset in the large parameter region admitted by our non-perturbative approach. An important implication of the non-perturbative approach is its flexibility in implementing the dynamical control scheme in a experimental setup. Our findings have exhibited several interesting features of the non-perturbative regimes such as the chain-size independence, pulse strength upper-bound, noncontinuous valid parameter regions, etc. Furthermore, we find that our non-perturbative scheme is robust against randomness in model fabrication and time-dependent random noise.

description: In this paper, we present the results of CARMA continuum and spectral line observations of the dense core Per-Bolo 45. Although this core has previously been classified as starless, we find evidence for an outflow and conclude that Per-Bolo 45 is actually an embedded, low-luminosity protostar. We discuss the impact of newly discovered, low-luminosity, embedded objects in the Perseus molecular cloud on starless core and protostar lifetimes. We estimate that the starless core lifetime has been overestimated by 4-18% and the Class 0/I protostellar lifetime has been underestimated by 5-20%. Given the relatively large systematic uncertainties involved in these calculations, variations on the order of 10% do not significantly change either core lifetimes or the expected protostellar luminosity function. Finally, we suggest that high resolution (sub)millimeter surveys of known cores lacking near-infrared and mid-infrared emission are necessary to make an accurate census of starless cores.

description: It is shown that optomechanical forces can cause nonlinear self-channelling of light in a planar dual-slab waveguide. A system of two parallel silica nanowebs, spaced ~100 nm and supported inside a fibre capillary, is studied theoretically and an iterative scheme developed to analyse its nonlinear optomechanical properties. Steady-state field distributions and mechanical deformation profiles are obtained, demonstrating that self-channelling is possible in realistic structures at launched powers as low as a few mW. The differential optical nonlinearity of the self-channelled mode can be as much as ten million times higher than the corresponding electronic Kerr nonlinearity. It is also intrinsically broadband, does not utilize resonant effects, can be viewed as a consequence of the extreme nonlocality of the mechanical response, and in fact is a notable example of a so-called "accessible" soliton.

description: When spatial correlations are short-range, the physics of strongly correlated systems is controlled by local quantum fluctuations. In those regimes, Dynamical Mean-Field Theory can be viewed as a `compass' which provides guidance on the relevant degrees of freedom and their effective dynamics over intermediate energy scales. These intermediate energy scales and associated crossovers play a crucial role in the physics of strongly correlated materials.

description: The analytical continuation average spectrum method (ASM) and maximum entropy (MaxEnt) method are applied to the dynamic response of a noninteracting resonant level model within the framework of the Kubo formula for electric conductivity. The frequency dependent conductivity is inferred from the imaginary time current-current correlation function for a wide range of temperatures, gate voltages and spectral densities representing the leads, and compared with exact results. We find that the MaxEnt provides more accurate results compared to the ASM over the full spectral range.

description: Topical administration permits targeted, sustained delivery of therapeutics to human skin. Delivery to the skin, however, is typically limited to lipophilic molecules with molecular weight of < 500 Da, capable of crossing the stratum corneum. Nevertheless, there are indications protein delivery may be possible in barrier deficient skin, a condition found in several inflammatory skin diseases such as psoriasis, using novel nanocarrier systems. Methods: Water in water thermo-nanoprecipitation; dynamic light scattering; zeta potential measurement; nanoparticle tracking analysis; atomic force microscopy; cryogenic transmission electron microscopy; UV absorption; centrifugal separation membranes; bicinchoninic acid assay; circular dichroism; TNF alpha binding ELISA; inflammatory skin equivalent construction; human skin biopsies; immunohistochemistry; fluorescence microscopy; western blot; monocyte derived Langerhans cells; ELISA Results: Here, we report the novel synthesis of thermoresponsive nanogels (tNG) and the stable encapsulation of the anti-TNFa fusion protein etanercept (ETR) (similar to 150 kDa) without alteration to its structure, as well as temperature triggered release from the tNGs. Novel tNG synthesis without the use of organic solvents was conducted, permitting in situ encapsulation of protein during assembly, something that holds great promise for easy manufacture and storage. Topical application of ETR loaded tNGs to inflammatory skin equivalents or tape striped human skin resulted in efficient ETR delivery throughout the SC and into the viable epidermis that correlated with clear anti-inflammatory effects. Notably, effective ETR delivery depended on temperature triggered release following topical application. Conclusion: Together these results indicate tNGs hold promise as a biocompatible and easy to manufacture vehicle for stable protein encapsulation and topical delivery into barrier-deficient skin.

description: (1) Background: Sexual violence (SV) is a major public health problem, with negative socio-economic, physical, mental, sexual, and reproductive health consequences. Migrants, applicants for international protection, and refugees (MARs) are vulnerable to SV. Since many European countries are seeing high migratory pressure, the development of prevention strategies and care paths focusing on victimised MARs is highly needed. To this end, this study reviews evidence on the prevalence of SV among MAR groups in Europe and the challenges encountered in research on this topic. (2) Methods: A critical interpretive synthesis of 25 peer-reviewed academic studies and 22 relevant grey literature documents was conducted based on a socio-ecological model. (3) Results: Evidence shows that SV is highly frequent in MARs in Europe, yet comparison with other groups is still difficult. Methodologically and ethically sound representative studies comparing between populations are still lacking. Challenges in researching SV in MARs are located at the intrapersonal, interpersonal, community, societal, and policy levels. (4) Conclusions: Future research should start with a clear definition of the concerned population and acts of SV to generate comparable data. Participatory qualitative research approaches could be applied to better grasp the complexity of interplaying determinants of SV in MARs.

description: The environs of supermassive black holes are among the universe's most extreme phenomena. Understanding the physical processes occurring in the vicinity of black holes may provide the key to answer a number of fundamental astrophysical questions including the detectability of strong gravity effects, the formation and propagation of relativistic jets, the origin of the highest energy gamma-rays and cosmic-rays, and the nature and evolution of the central engine in Active Galactic Nuclei (AGN). As a step towards this direction, this paper reviews some of the progress achieved in the field based on observations in the very high energy domain. It particularly focuses on non-thermal particle acceleration and emission processes that may occur in the rotating magnetospheres originating from accreting, supermassive black hole systems. Topics covered include direct electric field acceleration in the black hole's magnetosphere, ultra-high energy cosmic ray production, Blandford-Znajek mechanism, centrifugal acceleration and magnetic reconnection, along with the relevant efficiency constraints imposed by interactions with matter, radiation and fields. By way of application, a detailed discussion of well-known sources (Sgr A*; Cen A; M87; NGC1399) is presented.

description: The brain orchestrates organ function and regulates whole body metabolism by the concerted action of neurons and glia cells in the central nervous system. To do so, the brain has tremendously high energy consumption and relies mainly on glucose utilization and mitochondrial function in order to exert its function. As a consequence of high rate metabolism, mitochondria in the brain accumulate errors over time, such as mitochondrial DNA (mtDNA) mutations, reactive oxygen species, and misfolded and aggregated proteins. Thus, mitochondria need to employ specific mechanisms to avoid or ameliorate the rise of damaged proteins that contribute to aberrant mitochondrial function and oxidative stress. To maintain mitochondria homeostasis (mitostasis), cells evolved molecular chaperones that shuttle, refold, or in coordination with proteolytic systems, help to maintain a low steady-state level of misfolded/aggregated proteins. Their importance is exemplified by the occurrence of various brain diseases which exhibit reduced action of chaperones. Chaperone loss (expression and/or function) has been observed during aging, metabolic diseases such as type 2 diabetes and in neurode-generative diseases such as Alzheimer's (AD), Parkinson's (PD) or even Huntington's (HD) diseases, where the accumulation of damage proteins is evidenced. Within this perspective, we propose that proper brain function is maintained by the joint action of mitochondrial chaperones to ensure and maintain mitostasis contributing to brain health, and that upon failure, alter brain function which can cause metabolic diseases.

description: At Saturn electrons are trapped in the planet's magnetic field and accelerated to relativistic energies to form the radiation belts, but how this dramatic increase in electron energy occurs is still unknown. Until now the mechanism of radial diffusion has been assumed but we show here that in-situ acceleration through wave particle interactions, which initial studies dismissed as ineffectual at Saturn, is in fact a vital part of the energetic particle dynamics there. We present evidence from numerical simulations based on Cassini spacecraft data that a particular plasma wave, known as Z-mode, accelerates electrons to MeV energies inside 4 R-S (1 R-S = 60,330 km) through a Doppler shifted cyclotron resonant interaction. Our results show that the Z-mode waves observed are not oblique as previously assumed and are much better accelerators than O-mode waves, resulting in an electron energy spectrum that closely approaches observed values without any transport effects included.

Publisher: name: Universität Potsdam

Subjects: subject: 530 Physik

description: We present a general analysis of the cooling produced by losses on condensates or quasi-condensates. We study how the occupations of the collective phonon modes evolve in time, assuming that the loss process is slow enough so that each mode adiabatically follows the decrease of the mean density. The theory is valid for any loss process whose rate is proportional to the jth power of the density, but otherwise spatially uniform. We cover both homogeneous gases and systems confined in a smooth potential. For a low-dimensional gas, we can take into account the modified equation of state due to the broadening of the cloud width along the tightly confined directions, which occurs for large interactions. We find that at large times, the temperature decreases proportionally to the energy scale mc2, where m is the mass of the particles and c the sound velocity. We compute the asymptotic ratio of these two quantities for different limiting cases: a homogeneous gas in any dimension and a one-dimensional gas in a harmonic trap.

description: With a broad range of hosts, Salmonella enterica serovar Typhimurium (S. Typhimurium) is the major cause of gastroenteritis in human beings and systemic disease in susceptible mice strains. However, different S. Typhimurium strains differ in regard to virulence and host adaptation. Here, C57BL/6 mice were infected, respectively, with different S. Typhimurium strains SL1344 (calf), CVCC541 (chicken) and CMCC50115 (mutton) to determine their virulence and host immune responses. It was found that mice were less susceptible to infection by S. Typhimurium CVCC541 and CMCC50115 strains, with lower lethality and decreased bacterial burden in liver and spleen. Besides, S. Typhimurium strains CVCC541 and CMCC50115 enhanced host innate immune responses by increased frequencies of macrophages and neutrophils 3 days after infection. But SL1344 strain evaded immune response by inducing apoptosis of macrophages. Moreover, CVCC541 could elicit adaptive immune responses of host 11 days after infection upon examination of the proliferation and activation of CD4+ T cells. In addition, 125 and 138 unique mutant coding genes, respectively, in S. Typhimurium strains CVCC541 and CMCC50115 and 78 shared mutant coding genes were annotated by genomic alignment to SL1344 genome and the signal pathways involving these genes were further analyzed. The acquired results indicate that different original S. Typhimurium strains show differential virulence and may induce diverse immune responses in the same host infected.

description: We analyze the light curves of the recent solar eclipses measured by the Herzberg channel (200-220 nm) of the Large Yield RAdiometer (LYRA) onboard PROBA-2. The measurements allow us to accurately retrieve the center- to-limb variations (CLV) of the solar brightness. The formation height of the radiation depends on the observing angle so the examination of the CLV provide information about a broad range of heights in the solar atmosphere. We employ the 1D NLTE radiative transfer COde for Solar Irradiance (COSI) to model the measured light curves and corresponding CLV dependencies. The modeling is used to test and constrain the existing 1D models of the solar atmosphere, e.g. the temperature structure of the photosphere and the treatment of the pseudo- continuum opacities in the Herzberg continuum range. We show that COSI can accurately reproduce not only the irradiance from the entire solar disk, but also the measured CLV. It hence can be used as a reliable tool for modeling the variability of the spectral solar irradiance.

Childhood obesity: perceptions of the Calgary public

description: Bibliography: p. 105-117
description: The purpose of this study was to investigate perceptions about childhood obesity as held by the adult public in Calgary. In this cross sectional study, which was modeled after Hardus et al Int J Obes 2003;27:1465-71, adults were recruited from a shopping mall located in a sociodemographically diverse region of Calgary. A total of 264 adults completed a questionnaire on which they provided demographic information and rated the importance of 25 potential causes of obesity and 13 potential preventive measures. Principal components analysis was used to reduce the "cause" and "prevention" items respectively into a smaller number of internally consistent factors. T-test and ANOV A were then used to assess differences on factor scores by demographic variables. These analyses revealed differences by sex and by weight category. This study thus offers preliminary guidance about publicly acceptable intervention strategies for this important public health problem.
The persistence question of the species problem
Creators: name: Amitani, Yuichi
Publisher: name: University of British Columbia
Year: 2011

description: The species problem is the longstanding puzzle in biology regarding the nature of the species category or how to correctly define `species.' Although biologists and philosophers have grappled with it for quite some time, they have thus far failed to reach a general consensus on the matter. My dissertation explores the question of why this problem persists —— why biologists and philosophers remain bothered by the species problem, and have found no solution to it. I call this the persistence question of the species problem. This dissertation aims to answer this persistence question. My strategy is to divide this question into several sub-questions and to answer them. Those questions include: (a) Why does no definition command universal support? (b) How could biologists conduct their research concerning species without a unanimously accepted solution? For question (a), I put forward the argument from interest-relativity. The premises are: (I) biologists have different interests in species, (R) under some interest, biologists erect a set of species criteria and accept only the definition(s) that best satisfy them, and (N) a taxon satisfying one criterion often fails to satisfy another. It follows that there will be very few unanimously accepted definitions of species, because one definition under one interest will fail to satisfy criteria provoked by others. For the question (b), I pointed out two factors. First, when there is no unanimously accepted definition of species, biologists may fail to communicate effectively about species, because the definition of ‘species’ may vary among biologists. But biologists often agree regarding the reference of `species' and species names (like `Homo sapiens'), and we see that this has enabled them to avoid the possible communication breakdown in the history of biology. Second, the way in which biologists represent the notion of species is also relevant. There is a tendency in biologists to represent the species category with its prototype, good species and infer various attributes of the former from those of the latter. When biologists make this attribute substitution, they tend to ignore the complexities of the species problem and do their research without being bothered by them.

These events can give rise to local observed velocity sequences - a signature of a small fraction of debris from a common progenitor, passing at high velocity through the survey volume, near the pericenters of their eccentric orbits. The majority of the debris is found in much larger structures, whose morphologies are more cloud-like than stream-like and which lie at the orbital apocenters. Adopting this interpretation, the full-space motions represented by the observed velocity features are derived under the assumption that the members within each sequence share a common velocity. Orbit integrations are then used to trace the past and future trajectories of these stars across the sky revealing plausible associations with large, previously-discovered, cloud-like structures. The connections made between nearby velocity structures and these distant clouds represent preliminary steps towards developing coherent maps of such giant debris systems. These maps promise to provide new insights into the origin of debris clouds, new probes of Galactic history and structure, and new constraints on the high-velocity tails of the local dark matter distribution that are essential for interpreting direct detection experiments.

description: We investigated whether Tagalog-speaking children incrementally interpret the first noun as the agent, even if verbal and nominal markers for assigning thematic roles are given early in Tagalog sentences. We asked five- and seven-year-old children and adult controls to select which of two pictures of reversible actions matched the sentence they heard, while their looks to the pictures were tracked. Accuracy and eye-tracking data showed that agent-initial sentences were easier to comprehend than patient-initial sentences, but the effect of word order was modulated by voice. Moreover, our eye-tracking data provided evidence that, by the first noun phrase, seven-year-old children looked more to the target in the agent-initial compared to the patient-initial conditions, but this word order advantage was no longer observed by the second noun phrase. The findings support language processing and acquisition models which emphasize the role of frequency in developing heuristic strategies (e.g., Chang, Dell, & Bock, 2006).

description: The Threespine Stickleback (Gasterosteus aculeatus) is a fish commonly used for the study of adaptive radiation, phenotypic plasticity, parallel evolution, and epigenetic mechanisms. Information regarding stickleback development, however, is largely missing from the literature. Using 2D and 3D analysis, I characterized skeletal and soft tissue development in four phenotypically diverse populations of stickleback, three marine and one freshwater. Fish as early as 5 days post fertilization can be distinguished by population, and by 90 days post fertilization, stickleback juveniles have developed a nearly complete skeleton and have attained their population-specific phenotype. This research gives some of the first indications of phenotype development in the Threespine Stickleback, and suggests that juvenile stickleback may be a target of selection in the fish’s expansion into new habitats.

description: In a multi-user wireless network equipped with multiple relay nodes, some relays are more intelligent than other relay nodes. The intelligent relays are able to gather channel state information, perform linear processing and forward signals whereas the dumb relays is only able to serve as amplifiers. As the dumb relays are oblivious to the source and destination nodes, the wireless network can be modeled as a relay network with *smart instantaneous relay* only: the signals of source-destination arrive at the same time as source-relay-destination. Recently, instantaneous relaying is shown to improve the degrees-of-freedom of the network as compared to classical cut-set bound. In this paper, we study an achievable rate region and its boundary of the instantaneous interference relay channel in the scenario of (a) uninformed non-cooperative source-destination nodes (source and destination nodes are not aware of the existence of the relay and are non-cooperative) and (b) informed and cooperative source-destination nodes. Further, we examine the performance of interference neutralization: a relay strategy which is able to cancel interference signals at each destination node in the air. We observe that interference neutralization, although promise to achieve desired degrees-of-freedom, may not be feasible if relay has limited power. Simulation results show that the optimal relay strategies improve the achievable rate region and provide better user-fairness in both uninformed non-cooperative and informed cooperative scenarios.

Subjects: White coat effect (WCE); pseudo-resistant hypertension

description: Introduction: The prevalence of white coat effect (WCE) in patients with pseudo-resistant hypertension is not established locally. WCE may result in unwarranted intensification of therapy, leading to increased health costs, drug adverse effects, and decreased adherence to prescribed treatment. Therefore, the primary objective is to determine the prevalence of WCE and their clinical characteristics among patients with pseudo-resistant hypertension in Malaysia. Methodology: Patients suspected of pseudo-resistant hypertension on at least 3 anti-hypertensive drugs were recruited. Office blood pressure (BP) were repeated before being reassessed with a 24-hour ambulatory blood pressure monitoring (ABPM). Patients with an elevated office BP of >20/10 mmHg in contradictory to 24-hour BP of <130/80 mmHg were formally diagnosed as controlled hypertension with white coat effect. Results: Of the 430 patients screened, 413 with valid ABPM were analysed. Of which, 224 had controlled hypertension. Of which, 133 (59.4%) had WCE. Their mean age was 54.38 8.1, predominantly female (70.7%), Malay (39.8%) with underlying type 2 diabetes mellitus (75.9%), dyslipidaemia (88.7%), chronic kidney disease (20.3%) and Body Mass Index (BMI) of 30.8 5.6. Echocardiogram showed 34.8% with concentric left ventricular hypertrophy (LVH). Baseline office BP was 146.7 14.3/ 78.1 10.8 mmHg. In contrast, 24-hour BP was 115.0 7.5/ 69.7 5.7 mmHg, and the majority were non-dippers (62.4%). 97.7% were compliant to medication while taking 3.9 0.8 number of anti-hypertensive medications. Discussion/conclusion: WCE is prevalent in patients with pseudo-resistant hypertension (32.2%), similar to studies published on other populations. Therefore, identifying WCE in pseudo-resistant hypertension is important to prevent over-treatment. Hence, 24-hour ABPM is recommended to ascertain WCE and guide further management.

First Detection of a Pulsar above 100 GeV

description: We present the detection of pulsed gamma-ray emission from the Crab Pulsar above 100 GeV with the VERITAS array of atmospheric Cherenkov telescopes. Gamma-ray emission at theses energies is not expected in present pulsar models. We find that the photon spectrum of pulsed emission between 100 MeV and 400 GeV can be described by a broken power law, and that it is statistically preferred over a power law with an exponential cut-off. In the VERITAS energy range the spectrum can be described with a simple power law with a spectral index of -3.8 and a flux normalization at 150 GeV that is equivalent to 1 % of the Crab Nebula gamma-ray flux. The detection of pulsed emission above 100 GeV and the absence of an exponential cutoff rules out curvature radiation as the primary gamma-ray-producing mechanism. The pulse profile exhibits the characteristic two pulses of the Crab Pulsar at phases 0.0 and 0.4, albeit 2-3 times narrower than below 10 GeV. The narrowing can be interpreted as a tapered particle acceleration region in the magnetosphere. Our findings require that the emission region of the observed gamma rays be beyond 10 stellar radii from the neutron star.

description: The fascination with kingship has always involved questions of right. Attitudes towards individual rule cannot be separated from social conditions. Unfortunately, traditional theories of kingship have hinged upon the existence of social conditions which find little support in the evidence. The theories applied to early Germanic kingship place a great deal of emphasis upon the sacrality of the king's person and a belief that this sacrality was inherited. This meant the recognition of direct unilineal descent from a great ancestor. The available literary, legal and historical evidence does not support this. Early forms of Germanic kingship were fairly homogeneous. The crucial factor in selection was military ability. The most successful individual was acknowledged as being a favourite of the gods. The king was considered a microcosm of his kingdom, and he was guarded carefully. Certain conditions often gave the appearance of inherited kingships. The accumulation of wealth by certain families placed them in positions of authority. Support was established through client-patron relationships which could be purchased. The ab i 1 i t y to g iv e g i ft s o f arms and prop e r t y f i g u r e d prorninen tly in the select ion of kings. The king was only associated with the territory of his kingdom through the oaths of his supporting landholders. The kingdom was not treated as his personal property. With Christianity came the written word. The presence of communities not covered by the protection of family law challenged the universal practices of inheritance and blood-feud. The king's protection was expanded to incorporate the Church. The emergence of legal documents coincided with an increased interference by the king in social matters. The most prominent infringement of rights was the partitioning of the Frankish kingdom upon the death of Clovis. English and Frankish kingship took different directions from this point. The king in England remained a leader of tribal peoples, united by religion and law. The Merovingians developed a heightened form of Germanic sacrality based upon the fortune of Clovis. Associated with this was the inheritance of the territorial kingdom as defined by Roman civitas boundaries and written charters. The resistance to these artifical restrictions was only overcome by the might of the Carolingians and the recognition by the Church of German sacrality.
