Leadership, Communication and Religiosity in Higher Education Administration: Distinctions That Make a Difference

This project investigated the communicative and religious components of transformational leadership and job satisfaction in the context of higher education. Specifically, 224 CAO members of the Council of Independent Colleges completed a survey assessing their own leadership style, communication behavior, and religiosity. A stepwise multiple regression procedure revealed seven significant predictors of transformational leadership. The most important variables included attentiveness, openness, role negotiation, and intrinsic religious orientation. Additionally, a t-test compared a subset of CAOs from institutions affiliated with the Council of Christian Colleges and Universities with CAOs in non-affiliated institutions. Results revealed statistically significant differences in attentiveness, information support, exercise of transformational leadership, and religious identity, practice, and orientation. Lastly, a second stepwise regression procedure revealed five significant predictors of CAO job satisfaction including availability of emotional support, level of commitment to the job, and amount of religious activity. The paper concludes with a discussion of implications for conducting higher education administration in ways that best reflect religious ideals

MODELING OF THE ILOVICA-SHTUKA COPPER-GOLD DEPOSIT, MINERAL RESOURCE ESTIMATION AND CLASSIFICATION

The Ilovica – Shtuka project's mineral resource estimation has been defined in accordance with the reporting requirements outlined in the 2012 edition of the 2012 edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves” (the JORC Code). Statistical and grade continuity analyses were completed to characterise the mineralisation and subsequently used to develop grade interpolation parameters for the deposit. Exploratory data analysis highlighted a number of statistically differentiated grade populations, which were interpreted to be controlled by the following: stockwork intensity, oxidation state, supergene leaching and enrichment. Wireframe models were used to isolate grade populations into domains for the purpose of sample selection and to constrain the grade interpolation. Grade estimation was completed using ordinary kriging. The search ellipsoid dimen-sions and orientations were chosen to reflect the continuity revealed by geostatistical studies and optimised using quan-titative kriging neighbourhood analysis. The wireframe models were used within the sample selection and compositing routine and subsequently as a constraint to the grade estimation. In calculating dollar equivalent block values metal prices used are provided by Euromax management and are generated based on industry capacity analysis, global com-modity consumption and economic growth trends. A Mineral Resource classification scheme consistent with the JORC guidelines (2012) was applied. The estimates are categorised in the Measured, Indicated and Inferred mineral Resource categories, reported above a cut-off grade that defines the Resource as potentially mineable by open pit mining methods. Resource grade/ tonnage sensitivity graph were created based upon a range of dollar equivalent cut- offs for blocks within the Resource pit shell

A validated computational framework to evaluate the stiffness of 3D printed ankle foot orthoses

The purpose of this study was to create and validate a standardized framework for the evaluation of the ankle stiffness of two designs of 3D printed ankle foot orthoses (AFOs). The creation of four finite element (FE) models allowed patient-specific quantification of the stiffness and stress distribution over their specific range of motion during the second rocker of the gait. Validation was performed by comparing the model outputs with the results obtained from a dedicated experimental setup, which showed an overall good agreement with a maximum relative error of 10.38% in plantarflexion and 10.66% in dorsiflexion. The combination of advanced computer modelling algorithms and 3D printing techniques clearly shows potential to further improve the manufacturing process of AFOs

Development and clinical evaluation of laser-sintered ankle foot orthoses

Ankle foot orthoses (AFOs) are traditionally manufactured using vacuum thermoforming as shaping technology. Additive manufacturing has the potential to disruptively change the way these orthopaedic devices are produced. In this study, AFOs are developed which are virtually designed and produced with laser sintering as shaping technology. The mechanical and clinical performances of these laser-sintered AFOs are compared with traditionally manufactured AFO by asking seven patients (both children and adults) to walk with each type of AFO

Field Measurements of Terrestrial and Martian Dust Devils

Surface-based measurements of terrestrial and martian dust devils/convective vortices provided from mobile and stationary platforms are discussed. Imaging of terrestrial dust devils has quantified their rotational and vertical wind speeds, translation speeds, dimensions, dust load, and frequency of occurrence. Imaging of martian dust devils has provided translation speeds and constraints on dimensions, but only limited constraints on vertical motion within a vortex. The longer mission durations on Mars afforded by long operating robotic landers and rovers have provided statistical quantification of vortex occurrence (time-of-sol, and recently seasonal) that has until recently not been a primary outcome of more temporally limited terrestrial dust devil measurement campaigns. Terrestrial measurement campaigns have included a more extensive range of measured vortex parameters (pressure, wind, morphology, etc.) than have martian opportunities, with electric field and direct measure of dust abundance not yet obtained on Mars. No martian robotic mission has yet provided contemporaneous high frequency wind and pressure measurements. Comparison of measured terrestrial and martian dust devil characteristics suggests that martian dust devils are larger and possess faster maximum rotational wind speeds, that the absolute magnitude of the pressure deficit within a terrestrial dust devil is an order of magnitude greater than a martian dust devil, and that the time-of-day variation in vortex frequency is similar. Recent terrestrial investigations have demonstrated the presence of diagnostic dust devil signals within seismic and infrasound measurements; an upcoming Mars robotic mission will obtain similar measurement types

Middle Neolithic pits and a burial at West Amesbury, Wiltshire

Excavations on the south-eastern slopes of King Barrow Ridge, 1.5 km east of Stonehenge, revealed five pits, a grave and other features of Middle Neolithic date. Analysis of the pit assemblages and the partial inhumation interred in the grave has provided insights into lifeways in this landscape in the late fourth millennium cal BC. Evidence suggests that the area was visited by a pastoralist, mobile community on a semi-regular basis for a significant period, in late autumn or winter. Selected remnants of craft-working and consumption were deposited in pits, before deliberate infilling. These depositions repeatedly memorialised activity on the hillside at a time of contemporary activity elsewhere on King Barrow Ridge and at the future site of Stonehenge. Middle Neolithic pits are present in significant numbers across King Barrow Ridge, and alongside pits in the Durrington area, form one of the densest concentrations of such activity in the region. Long distance mobility is suggested by the possible Irish origins of the inhumation, the first Middle Neolithic individual excavated in the environs of Stonehenge. Whilst of significance for understanding the Middle Neolithic in the WHS and the region, this research also hints at the roots of Late Neolithic monumentalisation of this landscape

RESOURCE MODELLING AT THE ILOVICA-ŠTUKA PORPHYRY COPPER-GOLD DEPOSIT, EASTERN MACEDONIA

The Ilovica-Štuka porphyry system is located in southeast Macedonia, within the Tertiary belt associated with tectonic accretion along the western Tethyan belt. The intrusive is about 1.5 km in diameter and comprises a dacite-granodiorite plug, emplaced along the northeastern border of the Strumica graben. Mineralization is typical porphyry style veining, most intense within the potassic zone. The mineralization shows good continuity and homogeneity that lends itself well to bulk-mining methods. Modelling and estimation has been completed using Geovia Surpac. Exploratory data analysis highlighted a number of statistically differentiated grade populations, which were interpreted to be controlled by the following: alteration style, lithology, oxidation state elevation and stockwork intensity. Statistical and grade continuity analyses were completed to characterize the mineralization and subsequently used to develop grade interpolation parameters. Grade estimation was completed using ordinary kriging. The search ellipsoid dimensions and orientations were chosen to reflect the continuity revealed by geostatistical studies and optimized using quantitative kriging neighbourhood analysis. The mineral resource was classified according to CIM Definition Standards on Mineral Resources and Mineral Reserves (CIM 2010). Key words: Canadian Institute of Mining; Metallurgy and Petroleum (CIM) Definition Standards; EDA (exploratory data analysis); domaining; block model; ordinary kriging; kriging neighbourhood analysi
