title: Evolution of Public Enterprises Reform Policy in Tanzania: Privatisation of Banking, Electricity and Telecommunications

description: This empirical study attempts to contribute to existing knowledge on policy choice and employs historical and case study approaches in addressing Tanzania’s liberalisation and privatisation policy choice. The thesis focuses on four specific questions: why Tanzania’s liberalisation and privatisation policy was chosen; what considerations were taken into account; the theory that explains the choice; and lessons to be drawn from Tanzania’s experience. In liberalising and privatising its economic sectors, Tanzania was influenced by three main factors: compliance with the IMF and the World Bank conditionality for accessing loans from the two international financial institutions; lobbying and manipulation by a coalition of external institutions interested in controlling and exploiting the Tanzanian economy; and political corruption whereby state officials saw in liberalisation and privatisation an opportunity to benefit financially and enrich themselves. This research has also revealed that, contrary to the belief by the IMF and World Bank, the private sector is in fact not more efficient than the public sector, there is also rent seeking behaviour in the private sector, and ‘off-the-shelf’ policies do not work in all situations. The thesis concludes that in order for policy to achieve desired outcomes, government should adopt appropriate measures including matching policy objectives with the prevailing needs and circumstances in the country; and applying good governance in terms of transparency, accountability and civil society participation in policy making.
Force Free Waves and Black Hole Magnetospheric Causality

description: The force free approximation is often useful when describing tenuous plasmas in strong cosmic magnetic fields. Time evolution of any such system is governed by the information that can be transported along the characteristics of the plasma modes allowed by the force free constraint. This brief article elucidates, for the first time, the nature of the information that can be transported along the characteristics for each of the two plasma modes, the Alfven and fast modes. It is reassuring that these modes behave as one would expect if the perfect magnetohydrodynamic (MHD) modes in a magnetically dominated plasma were evaluated in the limit of zero plasma inertia (i.e., only allowed to propagate information consistent with the force free constraint). There are no properties of these waves that do not exist within the MHD theory, when this additional constraint on the current is imposed. The results of the characteristic analysis elucidates the nature of the causality violation in force free black hole magnetospheres. The most significant result from the standpoint of global causality is that charge and current perturbations can not be transported along the fast mode short wavelength characteristics in the force free limit.
description: Accepted by ApJ. This rectifies gross errors in a simple short wavelength force free calculation posted on astro-ph that was intended to discredit the MHD analysis of black hole GHM

description: We statistically examine long time sequences of Brownian motion for a nonequilibrium version of the Rayleigh piston model and confirm that the third cumulant of a long-time displacement for the nonequilibrium Brownian motion linearly increases with the observation time interval. We identify a multiplicative Langevin equation that can reproduce the cumulants of the long-time displacement up to at least the third order, as well as its mean, variance and skewness. The identified Langevin equation involves a velocity-dependent friction coefficient that breaks the time-reversibility and may act as a generator of the directionality. Our method to find the Langevin equation is not specific to the Rayleigh piston model but may be applied to a general time sequence in various fields.

description: There are many different approaches to using observations to constrain or determine the global cosmological parameters that describe our universe. Methods that rely upon a determination of the coordinate distance to high-redshift sources are particularly useful because they do not involve assumptions about the clustering properties of matter, or the evolution of this clustering. Two of the methods currently being used to determine the coordinate distance to high-redshift sources are the radio galaxy method and the supernova method. These methods are similar in their dependence on the coordinate distance. Here, the radio galaxy method is briefly described and results are presented. One of the underlying assumptions of the method is explored. In addition, the method is compared and contrasted to the supernova method. The constraints imposed on global cosmological parameters by radio galaxies are consistent with those imposed by supernovae. For a universe that is spatially flat with mean mass density $Ω_m$ in non-relativistic matter and mean mass density 1- $Ω_m$ in quintessence, radio galaxies alone indicate at 84 % confidence that the expansion of the universe is accelerating at the current epoch. And, independent of whether or not the universe is spatially flat, radio galaxies alone indicate at 95 % confidence that $Ω_m$ must be less than 0.6 at the current epoch.

description: The seryl nucleoside moiety (SB-217452) of the Trojan horse antibiotic albomycin exhibits broad spectrum antibiotic activity against various bacterial pathogens by targeting seryl tRNA synthetase (SerRS). The aim of the present study is to understand how the SB-217452 inhibits SerRSs of different species. First, the binding efficacy of SB-217452 in the dimeric SerRS from Thermus thermophilus (TtSerRS) in complex with tRNASer is compared with the binding of seryl adenylate (Ser-AMP). Multiple reasons for inhibition action of SB-217452 are revealed. In the next part, we have compared the binding event of SB-217452 in SerRS from Staphylococcus aureus (SaSerRS) and from Streptomyces sp. (SpSerRS1). First, quantum mechanical study (AIM analysis) shows that the network of interaction is stronger in SaSerRS:tRNA complex compared to the SpSerRS1:tRNA complex. This conclusion is in fair agreement with the observed IC50 values which show that the binding free energy of SB-217452 in the active site of SaSerRS is more favorable compared to that in SpSerRS1. The interactions of antibiotic with β sheets contribute to the differences in the binding behavior. Secondly, the classical simulation results corroborate the results of AIM analysis. Finally, metadynamics calculation of the free energy surface of the conformational change of the SB-217452 shows that the antibiotic binds in a unique catalytically non competent organization in SaSerRS:tRNA. In contrast, the antibiotic can bind in the active site of SpSerRS1:tRNA complex with multiple catalytically incompetent conformations. The present study provides a comprehensive molecular perspective of the inhibition mechanism of the antibiotic. Communicated by Ramaswamy H. Sarma

description: The Sun is believed to have been the recipient of a substantial amount of metal-rich material over the course of its evolution, particularly in the early stages of the Solar System. With a long diffusion timescale, the majority of this accreted matter should still exist in the solar convection zone, enhancing its observed surface abundance, and implying a lower-abundance core. While helioseismology rules out solar models with near-zero metallicity cores, some solar models with enhanced metallicity in the convection zone might be viable, as small perturbations to the standard model. Because of the reduced interior opacity and core temperature, the neutrino flux predicted for such models is lower than that predicted by the standard solar model. This paper examines how compatible inhomogeneous solar models of this kind are with the observed low and intermediate degree p-mode oscillation data, and with the solar neutrino data from the SNO Collaboration. We set an upper limit on how much metal-rich accretion took place during the early evolution of the Sun at about 2 Earth masses of iron (or about 40 Earth masses of meteoric material).

title: Molecular Mechanism of Efficient Treatment of Resistant Breast Cancer Using a Mitochondria-Targeting Compound

Subjects: subject: Breast cancer
subject: Her2high breast carcinomas
subject: Mitochondrial targeted tamoxifen (MitoTAM).

description: Cancer is one of the prevailing causes of death worldwide. The prognosis of this hard-to- treat disease is poor and may be attributed to high rates of mutations leading to heterogeneity of tumours, and thus requiring an invariant target to selectively combat malignant cells. Her2high breast carcinomas occur in up to 30% of breast cancer patients and remain to be one of the hardest-to-treat breast cancers. The central dogma of Her2 localised at the plasmatic membrane has allowed for the development of commercially available antibody-based therapies epitomised by Herceptin™. However, Herceptin™ is not always efficient, causing re-lapse and even worse prognosis. Tamoxifen, a hormone- based agent, is a frequently used drug for estrogen-positive breast cancer patients, targeting mitochondria at supra-pharmacological doses. Thus, this study focuses on a novel therapeutic approach to combat resistant cancers such as Her2high breast cancers. Intriguingly, we observed, along with only one other study, that Her2 is also present in mitochondria of Her2high cells and tumours, probably altering their bioenergetic metabolism. We also show that Her2high cells exhibit higher mitochondrial membrane potential, and exhibit higher respiration through oxidative phosphorylation compared to Her2low cells. Further investigations of these cells show increased levels of complex I of the ETC, as well as the respirasome. However, the mechanism of Her2 translocation to mitochondria is not understood. Our findings led us to anticipate that targeting mitochondria could be an effective mode of therapy especially, but not limited to, resistant Her2high breast carcinomas. Due to this notion, we synthesised a mitochondrially targeted anti-cancer agent acting via the mitochondrial ETC, and evaluated the mechanism of its efficacy towards Her2high cells. The new compound that is the focus of this project is mitochondrial targeted tamoxifen (MitoTAM).

description: Nonrelativistic string theory is described by a sigma model with a relativistic worldsheet and a nonrelativistic target spacetime geometry, that is called string Newton-Cartan geometry. In this paper we obtain string Newton-Cartan geometry as a limit of the Riemannian geometry of General Relativity with a fluxless two-form field. We then apply the same limit to relativistic string theory in curved background fields and show that it leads to nonrelativistic string theory in a string Newton-Cartan geometry coupled to a Kalb-Ramond and dilaton field background. Finally, we use our limiting procedure to study the spacetime equations of motion and the T-duality transformations of nonrelativistic string theory. Our results reproduce the recent studies of beta-functions and T-duality of nonrelativistic string theory obtained from the microscopic worldsheet definition of nonrelativistic string theory.

description: We have obtained low resolution spectra of nineteen red and blue low surface brightness galaxies, using the Marcario Low Resolution Spectrograph on the 9.2m Hobby-Eberly Telescope. These galaxies form a very heterogeneous class, whose spectra qualitatively resemble those of high surface brightness galaxies covering the full range of spectra seen in galaxies of Hubble types from E to Irr. We use a combination of emission line (EW(Halpha), NII/Halpha) and absorption line (Mgb, Hbeta, ) based diagnostics to investigate the star-formation and chemical enrichment histories of these galaxies. These are diverse, with some galaxies having low metallicity and very young mean stellar ages, and other galaxies showing old, super-solar metallicity stellar populations. In contrast with some previous studies which found a strong trend of decreasing metallicity with decreasing central surface brightness, we find a population of galaxies with low surface brightness and near-solar metallicity. Correlations between several of the gas phase and stellar population age and metallicity indicators are used to place contraints on plausible evolutionary scenarios for LSB galaxies. The redshift range spanned by these galaxies is broad, with radial velocities from 3400 km/s to more than 65000 km/s. A subset of the sample galaxies have published HI redshifts and gas masses based on observations with the Arecibo 305m single-dish radio telescope, which place these galaxies far off of the mean Tully-Fisher relation. Our new optical redshifts do not agree with the published HI redshifts for these galaxies. Most of the discrepancies can be explained by beam confusion in the Arecibo observations, causing erroneous HI detections for some of the galaxies.

description: Control of the crystallization process is central to developing novel materials with atomic precision to meet the demands of electronic and quantum technology applications. Semiconductor nanowires grown by the vapor-liquid-solid process are a promising material system in which the ability to form components with structure and composition not achievable in bulk is well-established. Here we use in situ TEM imaging of GaAs nanowire growth to understand the processes by which the growth dynamics are connected to the experimental parameters. We find that two sequential steps in the crystallization process - nucleation and layer growth - can occur on similar time scales and can be controlled independently using different growth parameters. Importantly, the layer growth process contributes significantly to the growth time for all conditions, and will play a major role in determining material properties. The results are understood through theoretical simulations correlating the growth dynamics, liquid droplet and experimental parameters.
description: Differences in comparison to previous version: 1) Title- To avoid unlikely but possible confusion of the term 'step-flow' we call it layer growth in this new version. 2) The data and interpretations are mostly the same as in previous version, but presented in a modified perspective. 3) The simulation was refined further

description: X-ray flashes (XRFs) are a new type of fast transient source observed with the BeppoSAX Wide Field Cameras (WFC) at a rate of about four per year. Apart from their large fraction of 2-26 keV X-rays, the bulk properties of these events are similar to those of classical gamma-ray bursts (GRBs). By investigating the wide-band spectra of ten events detected in common with WFC and BATSE, we explore the possibility that XRFs are a low-energy branch of the GRB population. We find that XRF spectra are similar to those of GRBs, and that their low peak energies could be an extension of known GRB properties.

description: Here we systematically explore the use of pulsed laser deposition technique (PLD) to grow three basic oxides that have rocksalt structure but different chemical stability in the ambient atmosphere: NiO (stable), MnO (metastable) and EuO (unstable). By tuning laser fluence, an epitaxial single-phase nickel oxide thin-film growth can be achieved in a wide range of temperatures from 10 to 750 °C. At the lowest growth temperature, the out-of-plane strain raises to 1.5%, which is five times bigger than that in a NiO film grown at 750 °C. MnO thin films that had long-range ordered were successfully deposited on the MgO substrates after appropriate tuning of deposition parameters. The growth of MnO phase was strongly influenced by substrate temperature and laser fluence. EuO films with satisfactory quality were deposited by PLD after oxygen availability had been minimized. Synthesis of EuO thin films at rather low growth temperature prevented thermally-driven lattice relaxation and allowed growth of strained films. Overall, PLD was a quick and reliable method to grow binary oxides with rocksalt structure in high quality that can satisfy requirements for applications and for basic research.

description: The last 10-20 years has seen a profound shift in views of how the Galaxy's halo formed. The idea of a monolithic early collapse of a single system (Eggen, Lynden-Bell and Sandage 1962) has been challenged by observations at high redshift and by cosmological models of structure formation. These findings imply that we should see clear evidence of hierarchical formation processes in nearby galaxies. Recent studies of our Galaxy, made possible by large-scale CCD surveys such as the Sloan Digital Sky Survey (SDSS), have begun to reveal tantalizing evidence of substructure in the outer halo. We review evidence for tidal streams associated with known Milky Way satellites and for star streams whose progenitors are still unknown. This includes results from the SDSS and our own ongoing pencil-beam halo survey, the Spaghetti survey.

description: Business Process Compliance are three words which scholars use to describe what happens, or should happen, when two very di erent worlds collide. The first world is meant to represent enterprises and how they do what they do or, more simply, which procedures and processes they adopt to o er improved products to their customers. Scholars of the field refer to the Business Process Management as a “process optimisation process” and they study approaches, methodologies, and formal languages to describe and improve what they esteem as the heart of every organisation, the business process. A business process can be visualised as a self-contained, temporal, and logical order in which a set of activities ( tasks) are executed to achieve some business objectives. Within a business process, much information is available: The control flow describes what can be done and when, while the relevant data clarify what needs to be work on as well as which actors will do the work. The second world is the world of governments, of consortia, of all those entities which have enough power to create regulations, norms, and policies which directly impact organisations. Such entities state the boundaries of legality by imposing which actions can be considered legal to be performed within the aforementioned business processes, and which actions should be avoided in order not to incur severe sanctions.

description: We report estimates of the masses of the component stars in the pre-main-sequence spectroscopic binary UZ Tau E. These results come from the combination of our measurements of the mass ratio, M2/M1=0.28 +/-0.01, obtained using high resolution H-band spectroscopy, with the total mass of the system, (1.31 +/-0.08)(D/140pc) M_sun, derived from millimeter observations of the circumbinary disk (Simon et al. 2000). The masses of the primary and secondary are (1.016 +/-0.065)(D/140pc) M_sun and (0.294 +/-0.027)(D/140pc) M_sun, respectively. Using the orbital parameters determined from our six epochs of observation, we find that the inclination of the binary orbit, 59.8 +/-4.4 degrees, is consistent with that determined for the circumbinary disk from the millimeter observations, indicating that the disk and binary orbits are probably coplanar.

 Type species (by original designation) Neritina rubida Pease, 1867; Recent.
 Description: The shell is small, solid, with a relatively flat spire. The protoconch is multispiral tilted relative to the teleoconch coiling axis and ornamented with numerous minute pits. The teleoconch ornament consists principally on growth lines. The inner lip septum is flat and the adaxial margin is straight without teeth; the outer lip is prosocline without teeth.
 NERITILIA BISINUATA SP. NOV.
(FIG. 2)
 Etymology: From sinuatus (Latin), sinuous, referring to the shape of the outer lip.
 Type specimens: Holotype, coll. Le Renard (MNHN- LR67776A), 2 paratypes, coll. Le Renard (MNHN- LR67776B).
 Type locality and horizon: France, Loire-Atlantique, Saffré ‘ Le Bois-Gouët’, Middle Eocene (Lutetian).
 Other material examined: Middle Eocene, France, Loire-Atlantique, Saffré ‘ Le Bois-Gouët’, Middle Eocene (Lutetian), coll. Le Renard, 2 ex. (MNHN- LR6834).
 Measurements (holotype): Height = 1.2 mm; max. width = 1.45 mm.
 Description: The shell is minute, solid, very elongate neritiform with a relatively high spire for the group. The protoconch is multispiral, eroded but clearly tilted relative to the teleoconch. Teleoconch whorls up to 1.4 in number, increasing rapidly in size, inflated with a round periphery. The sutural line is gently impressed. The surface of the shell is relatively altered but one can distinguish spiral ridges and sinuous growth lines, which are particularly strong close to the aperture. The semicircular aperture is relatively small and inclined at about 42∞ relative to the teleoconch coiling axis. The outer lip is prosocline and sinuous with two notches, widely bevelled and slightly dilated outward. The inner lip is covered with a smooth, extensive callus; the adaxial margin is straight, without teeth.
 Remarks: This very small species is unique within Neritilia because of the presence of well-developed spiral ridges and strong sinuous growth lines. It is also the smallest Neritilia species known.

description: Years to decade-long cyclic orbital period changes have been observed in several classes of close binary systems including Algols, W Ursae Majoris and RS Canum Venaticorum systems, and the cataclysmic variables. The origin of these changes is unknown, but mass loss, apsidal motion, magnetic activity, and the presence of a third body have all been proposed. In this paper we use new CCD observations and the century-long historical record of the times of primary eclipse for WW Cygni to explore the cause of these period changes. WW Cygni is an Algol binary whose orbital period undergoes a 56 year cyclic variation with an amplitude of approximately 0.02 days. We consider and reject the hypotheses of mass transfer, mass loss, apsidal motion and the gravitational influence of an unseen companion as the cause for these changes. A model proposed by Applegate, which invokes changes in the gravitational quadrupole moment of the convective and rotating secondary star, is the most likely explanation of this star's orbital period changes. This finding is based on an examination of WW Cygni's residual O-C curve and an analysis of the period changes seen in 66 other Algols. Variations in the gravitational quadrupole moment are also considered to be the most likely explanation for the cyclic period changes observed in several different types of binary systems.

description: This thesis describes the cytotoxicity and phytochemical screening of 16 selected medicinal plants collected from the tidal forests of the coastal Sundarban and locations within the Khulna district of Bangladesh. The selected plants were successively extracted with n-hexane, dichloromethane, methanol and water. The methanol and aqueous extracts were then screened for cytotoxic activity (MTT assay) against one normal mouse fibroblast and three human cancer cell lines (gastric, colon and breast cancer). The results supported some of the traditional uses and reported cytotoxic activity for some of these plants. It identified some plant extracts (Hygrophila auriculata, Hibiscus tiliaceous and Limnophila indica) with selective cytotoxic activity to cancer cells (IC50 1.1 - 1.6 mg/mL) but non-toxic to normal mouse fibroblast cells. Some extracts (Acrostichum aureum, Ammannia baccifera, Argemone mexicana, Limnophila indica, Clerodendron inerme, Cynometra ramiflora and Xylocarpus moluccensis) showed low cytotoxicity against mouse fibroblast (IC50 > 2.5 mg/mL) but selective potent toxicity against cancer cells (IC50 0.2 - 2.3 mg/mL). Four extracts (Adiantum caudatum, Hibiscus tiliaceous and Blumea lacera) showed cytotoxic activity against all the cell lines tested in the study. The methanolic and aqueous extracts of B. lacera were identified as having the most potent cytotoxic activity against all cell lines with IC50 0.01 - 0.08 mg/mL. Reversed-phase analytical HPLC profiling of all extracts was carried out with extracts, demonstrating low toxicity against normal mouse fibroblast cells, but selective high toxicity against the three cancerous cell lines (A. aureum and A. baccifera) and highest toxicity against all the cell lines (B. lacera). Extracts from these plants were further investigated by LC-MS. A. aureum was then selected and further investigated with one compound subsequently being isolated from n-hexane fraction and twelve compounds from the methanolic fraction. Three compounds were identified as novel natural products, namely (2'Smethylhexyl) (2''S-methyl-5''-acetylpentyl) phthalate (1), (2R, 3S)-sulfated pterosin C (2) and (2S, 3S)-sulfated pterosin C (5).
Common envelope to explosion delay time of type Ia supernovae

description: I study the rate of type Ia supernovae (SNe Ia) within about a million years after the assumed common envelope evolution (CEE) that forms the progenitors of these SNe Ia, and find that the population of SNe Ia with short CEE to explosion delay (CEED) time is ~fewx0.1 of all SNe Ia. I also claim for an expression for the rate of these SNe Ia that occur at short times after the CEE, t(CEED)<10^6 year, that is different from that of the delay time distribution (DTD) billions of years after star formation. This tentatively hints that the physical processes that determine the short CEED time distribution (CEEDTD) are different (at least to some extend) from those that determine the DTD at billions of years. To reach these conclusions I examine SNe Ia that interact with a circumstellar matter (CSM) within months after explosion, so called SNe Ia-CSM, and the rate of SNe Ia that on a time scale of tens to hundreds of years interact with a CSM that might have been a planetary nebula, so called SNe Ia inside a planetary nebula (SNIPs). I assume that the CSM in these populations results from a CEE, and hence this study is relevant mainly to the core degenerate (CD) scenario, to the double degenerate (DD) scenario, to the double detonation (DDet) scenario with white dwarf companions, and to the CEE-wind channel of the single degenerate (SD) scenario.

subject: Medium strength steels

description: The hydrogen embrittlement of materials is a major concern for the steel industry, this project is motivated by the need of an accurate quantification of small amounts of absorbed hydrogen in steels and understand the kinetics of desorption of hydrogen from within the steel. A novel thermal desorption spectrometer (TDS) has been designed, assembled, tested and calibrated to investigate the intriguing kinetics of hydrogen in steels and consequently be used as a tool to understand the hydrogen embrittlement phenomenon. In Chapter 1, a brief literature review of the wide use of medium and high strength steels in industry is presented to highlight the importance of the potential influence that hydrogen embrittlement has nowadays in the global economy. Likewise, a summary of the relevant work performed throughout the last decades on the understanding of this phenomenon is presented. A major comparison between the available techniques for the quantification of hydrogen in steel and other materials is also displayed highlighting the advantages and disadvantages of thermal desorption spectroscopy as a tool to measure hydrogen content in steels. Finally, the current mathematical theory is described and explained to model the kinetics of hydrogen absorbed in steels. Chapter 2 encompasses the major and latest knowledge gained for the understanding of hydrogen embrittlement using thermal desorption spectroscopy. This chapter includes a comparison between the different techniques and approaches by previous researchers to use the thermal desorption of hydrogen to tackle the hydrogen embrittlement on steels and other materials. Finally, the major contributions of TDS on the surface and non-surface science are examined in detail, the mathematical approach used is described in detail and comparisons between the different approaches are discussed.

description: Background: Diagnostic errors are a major patient safety concern in primary healthcare and emergency care. These settings involve a high degree of uncertainty regarding patients’ diagnoses and appear to be those most prone to diagnostic errors. Diagnostic errors comprise missed, delayed, or incorrect diagnoses preventing the patient from receiving correct and timely treatment. Data regarding which diagnoses are affected in these settings are scarce. Objectives: To understand the distribution of diagnoses among reported diagnostic errors in primary health and emergency care as a step towards creating countermeasures for safer care. Methods: A retrospective and descriptive cohort study investigating reported diagnostic errors. A nationwide cohort was collected from two databases. The study was performed in Sweden from 1 January 2011 until 31 December 2016. The setting was primary healthcare and emergency departments. Results: In total, 4830 cases of preventable harm were identified. Of these, 2208 (46%) were due to diagnostic errors. Diagnoses affected in primary care were cancer (37% and 23%, respectively, in the two databases; mostly colon and skin), fractures (mostly hand), heart disease (mostly myocardial infarction), and rupture of tendons (mostly Achilles). Of the diagnostic errors in the emergency department, fractures constituted 24% (mostly hand and wrist, 29%). Rupture/injury of muscle/tendon constituted 19% (mostly finger tendons, rotator cuff tendons, and Achilles tendon). Conclusion: Our findings show that the most frequently missed diagnoses among reported harm were cancers in primary care and fractures in the emergency departments.

description: Nearly four in ten state school principals in Queensland are teaching principal. They work alone or with one other teacher in schools. Yet these teaching principals, located in isolated country areas attract limited attention in research into school leadership. They seem absent in theoretical models of educational leadership built from analyses of principals in large urban schools. In effect, smaller schools are viewed as ‘scaled down’ versions of larger schools, underpinning a false assumption that leadership and managerial approaches in small remote schools are similar to those in larger urban schools. Or the problem is dismissed. If there is only one full-time staff member—the teaching principal—is leadership possible and if so, what influences it? The purpose of this study was to examine teaching principal leadership as a particular phenomenon of school leadership. This was done by exploring the experiential accounts of teaching principals in one-teacher schools in remote rural Queensland settings. Their accounts describe their experiences and perceptions of the leadership practice needed to lead their schools, the influences upon this practice, their reactions to those influences and what constituted success in leadership. A case study design was used, guided by the theoretical underpinnings of the symbolic interactionist, who argues that meaning is to be found in the interactions between social actors. Qualitative data were derived from six beginning teaching principals’ perceptions of experiences related to practice. Data were analysed using grounded theory methods, especially with the use of constant comparison. A cross case comparison showed a number of consistent influences on leadership. Findings from the study extend recent reconceptualisations of school leadership particularly, understanding the importance of relationship building. Relationship building in the remote rural settings studied occurred at various levels: professional, school-based, personal, and community-wide. Principals who understand the importance of relationship building—especially its personal and community-wide facets—who take the initiative in establishing and nurturing relationships and improving them through reflection over time, are more successful at motivating, inspiring, and aligning country people to facilitate change. The acquisition of supportive relationships is presented as a possible precursor to school leadership in small remote rural school settings.

description: We consider deformation of a generic $d$ dimensional ($d\geq 2$) large-$N$ CFT on a sphere by a spin-0 operator which is bilinear in the components of the stress tensor. Such a deformation has been proposed to be holographically dual to an $AdS_{d+1}$ bulk with a hard radial cut-off. We compute the exact partition function and find the entanglement entropy from the field theory side in various dimensions and compare with the corresponding holographic results. We also compute renormalized entanglement entropy both in field theory and holography and find complete agreement between them.
