    Whereas music both unlocks and fuels devotion as well as strengthens mental faculties, whereas teamwork and shared experiences deepen familial bonds, whereas the Bible is the root of all knowledge and wisdom, the need for The Music Making Family has arisen. Colossians 3:16 states, “Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms, hymns, and spiritual songs, with thankfulness in your hearts to God.” The purpose of this qualitative study is to provide teachers, whether in private school, public school, a religious entity, in a standalone studio, instructional material for preschool and adult students together in one classroom including. This instructional material includes explaining the benefits of teaching one concept to multiple levels of intelligence; designing a curriculum plan for dual-aged groups built upon biblical truths and encouraging relationships within the immediate family unit. Young children learn best through music and play. They are most heavily influenced by those who care for them daily. For them to have any true wisdom, they must be filled with and instructed by the divine writings of scripture, where the truest and greatest story is told. The Music Making Family curriculum combines all of these elements to provide the entire family with a rich, engaging, Bible-saturated music experience that not only provides a music education suitable for child and parent alike, but models how every form of education finds its origin in the Creator

    Dynamics of methane ebullition from a peat monolith revealed from a dynamic flux chamber system

    Get PDF
    Methane (CH4) ebullition in northern peatlands is poorly quantified in part due to its high spatiotemporal variability. In this study, a dynamic flux chamber (DFC) system was used to continuously measure CH4 fluxes from a monolith of near‐surface Sphagnum peat at the laboratory scale to understand the complex behavior of CH4 ebullition. Coincident transmission ground penetrating radar measurements of gas content were also acquired at three depths within the monolith. A graphical method was developed to separate diffusion, steady ebullition, and episodic ebullition fluxes from the total CH4 flux recorded and to identify the timing and CH4 content of individual ebullition events. The results show that the application of the DFC had minimal disturbance on air‐peat CH4 exchange and estimated ebullition fluxes were not sensitive to the uncertainties associated with the graphical model. Steady and episodic ebullition fluxes were estimated to be averagely 36 ± 24% and 38 ± 24% of the total fluxes over the study period, respectively. The coupling between episodic CH4 ebullition and gas content within the three layers supports the existence of a threshold gas content regulating CH4 ebullition. However, the threshold at which active ebullition commenced varied between peat layers with a larger threshold (0.14 m3 m−3) observed in the deeper layers, suggesting that the peat physical structure controls gas bubble dynamics in peat. Temperature variation (23°C to 27°C) was likely only responsible for small episodic ebullition events from the upper peat layer, while large ebullition events from the deeper layers were most likely triggered by drops in atmospheric pressure

    Quantum-Dot Cellular Automata using Buried Dopants

    Full text link
    The use of buried dopants to construct quantum-dot cellular automata is investigated as an alternative to conventional electronic devices for information transport and elementary computation. This provides a limit in terms of miniaturisation for this type of system as each potential well is formed by a single dopant atom. As an example, phosphorous donors in silicon are found to have good energy level separation with incoherent switching times of the order of microseconds. However, we also illustrate the possibility of ultra-fast quantum coherent switching via adiabatic evolution. The switching speeds are numerically calculated and found to be 10's of picoseconds or less for a single cell. The effect of decoherence is also simulated in the form of a dephasing process and limits are estimated for operation with finite dephasing. The advantages and limitations of this scheme over the more conventional quantum-dot based scheme are discussed. The use of a buried donor cellular automata system is also discussed as an architecture for testing several aspects of buried donor based quantum computing schemes.Comment: Minor changes in response to referees comments. Improved section on scaling and added plot of incoherent switching time

    Ecohydrologically important subsurface structures in peatlands revealed by ground-penetrating radar and complex conductivity surveys.

    The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow. Subsurface peat structures are routinely derived from the inspection of peat cores. However, logistical limits on the number of cores that can be collected means that the horizontal extent of these structures must be inferred. We consider whether subsurface patterns in peat physical properties can be mapped in detail over large areas with ground-penetrating radar (GPR) and complex conductivity by comparing geophysical measurements with peat core data along a 36 m transect through different microhabitats at Caribou Bog, Maine. The geophysical methods show promise. Peat horizons produced radar reflections because of changes in the volumetric moisture content. Although these reflections could not be directly correlated with the peat core data, they were related to the depth-averaged peat properties which varied markedly between the microhabitats. Well-decomposed peat below a hollow was characterized by a discontinuous sequence of chaotic wavy reflections, while distinct layering of the peat below an area of hummocks coincided with a pattern of parallel planar reflections. The complex conductivity survey showed spatial variation in the real and imaginary conductivities which resulted from changes in the pore water conductivity; peat structures may also have influenced the spatial pattern in the complex conductivity. The GPR and complex conductivity surveys enabled the developmental history of the different microhabitats along the studied transect to be inferred

    Investigating Peatland Stratigraphy and Hydrogeology Using Integrated Electrical Geophysics

    Hydrology has been suggested as the mechanism controlling vegetation and related surficial pore-water chemistry in large peatlands. Peatland hydrology influences the carbon dynamics within these large carbon reservoirs and will influence their response to global warming. A geophysical survey was completed in Caribou Bog, a large peatland in Maine, to evaluate peatland stratigraphy and hydrology. Geophysical measurements were integrated with direct measurements of peat stratigraphy from probing, fluid chemistry, and vegetation patterns in the peatland. Consistent with previous field studies, ground-penetrating radar (GPR) was an excellent method for delineating peatland stratigraphy. Prominent reflectors from the peat-lake sediment and lake sediment-mineral soil contacts were precisely recorded up to 8 m deep. Two-dimensional resistivity and induced polarization imaging were used to investigate stratigraphy beneath the mineral soil, beyond the range of GPR. We observe that the peat is chargeable, and that IP imaging is an alternative method for defining peat thickness. The chargeability of peat is attributed to the high surface-charge density on partially decomposed organic matter. The electrical conductivity imaging resolved glaciomarine sediment thickness (a confining layer) and its variability across the basin. Comparison of the bulk conductivity images with peatland vegetation revealed a correlation between confining layer thickness and dominant vegetation type, suggesting that stratigraphy exerts a control on hydrogeology and vegetation distribution within this peatland. Terrain conductivity measured with a Geonics EM31 meter correlated with confining glaciomarine sediment thickness and was an effective method for estimating variability in glaciomarine sediment thickness over approximately 18 km(2). Our understanding of the hydrogeology, stratigraphy, and controls on vegetation growth in this peatland was much enhanced from the geophysical study

    Validating a Novel New Instrument for Measuring Firm Managers' Intellectual Property Management Practices: A study of biotechnology firms

    Get PDF
    Purpose: The purpose of this research project was to pilot and validate a new instrument to measure firm intellectual property (IP) management practices.Methodology/Approach: A survey instrument was developed in consultation with a Perth-based firm of patent attorneys specialising in IP management services. The survey was piloted by random mail-out to 357 biotechnology firms, 68 of which returned a useable response. IP managers' responses to the following seven dimensions of extent of IP management practice were measured on a 5-point Likert-scale: 1) Record-keeping and management practices (22 items); 2) IP capture and protection mechanisms (10 items); 3) Use of IP management services or traditional patent attorney services (9 items); 4) Defensive measures (12 items); 5) Business Plan and strategic vision (9 items); 6) Knowledge of the IP landscape (9 items); and, 7) Promoting an IP culture (7 items). Factor Analysis and Principle Component Analysis extraction method with Varimax Rotation were used to identify factors measured by our instrument.Findings: Between two and seven factors were extracted for each of the dimensions measuring IP management practices, explaining between 51% (IP Defensive Measures) to 74% (IP management services and traditional patent attorney services) of the cumulative variance on any one factors. Scrutiny of the Component Matrices for a common thread amongst large loadings indicated thirteen actual measures of IP management practices perceived by biotechnology firm IP managers; with high Cronbach's Alpha reliability.Research limitations/implications: Factor analysis of this instrument revealed that IP managers' responses were loading on 13 factors instead of the original 7 anticipated dimensions to the measure. The spread of 78 item was reduced to a more relevant and economical measure with 56 items. As scrutiny of the factor analysis has revealed increasing heterogeneity to IP management practices in the biotechnology industry, it might be interesting to repeat the study for IP managers in another industry. A limitation of the study is its Australian biotechnology context and also that no concession was made in the measure for the effect of firm vertical disintegration.Originality/value: To our knowledge this is a novel project. We have validated and streamlined a new IP management practices instrument with advice from a practicing firm of IP management consultants. The instrument should be useful to high-technology firms as a checklist of IP management practices for innovation management. It should also be a valuable measurement tool for academics, firms and industries wanting to characterise the nature of firm-level IP management practices

    Characterization of reactive transport by 3-D electrical resistivity tomography (ERT) under unsaturated conditions

    The leaching of nitrate from intensively used arable soil is of major concern in many countries. In this study, we show how time lapse electrical resistivity tomography (ERT) can be used to characterize spatially heterogeneous processes of ion production, consumption, and transport in soils. A controlled release fertilizer was introduced into an undisturbed soil core in a laboratory lysimeter and subjected to infiltration events. The production of ions resulting from processes associated with nitrification and their transport through the soil core was observed by time lapse ERT and analysis of seepage water samples from a multicompartment sampler. ERT images show development and propagation of a high-conductivity plume from the fertilizer source zone. Molar amounts of nitrate produced in and exported from the soil core could be well reproduced by time lapse ERT using a spatial moment analysis. Furthermore, we observed that several shape measures of local breakthrough-curves (BTCs) of seepage water conductivity and nitrate derived by effluent analyses and BTCs of bulk conductivity derived by ERT are highly correlated, indicating the preservation of spatial differences of the plume breakthrough in the ERT data. Also differences between nitrate breakthrough and a conservative tracer breakthrough can be observed by ERT. However, the estimation of target ion concentrations by ERT is error bound and the smoothing algorithm of the inversion masks spatial conductivity differences. This results in difficulties reproducing spatial differences of ion source functions and variances of travel times. Despite the observed limitations, we conclude that time lapse ERT can be qualitatively and quantitatively informative with respect to processes affecting the fate of nitrate in arable soils

    Gordon Brown's misplaced Smithian appeal : the eclipse of sympathy in changing British welfare norms

    Get PDF
    Gordon Brown has eagerly lauded his fellow Kirkcaldy citizen, Adam Smith, as his main policy inspiration. This article tests the rigour of such a claim by matching Brown's promotion of Smithian ‘sympathy’ as the centrepiece of his programme for government with the changes introduced by his Treasury to the British welfare model. In the 1970s, Thomas Wilson showed that the traditions of the post-war British welfare state were compatible with a modified form of Smithian sympathy socialised at the level of the state. New Labour has set about reforming the welfare model with respect to both its underlying institutions and the basic subjectivities of its recipients. I show that Brown's substantive preference for an asset-based system of welfare moves those subjectivities away from the ‘relational self’ of Smithian sympathy and towards a much more ‘autonomous self’. Consequently, I conclude that it is stretching Smith's concept of sympathy too far, even in a modified socialised form, to associate it with New Labour's asset-based system of welfare
