Art, Artists and Pedagogy
This volume has been brought together to generate new ideas and provoke discussion about what constitutes arts education in the twenty-first century, both within the institution and beyond. Art, Artists and Pedagogy is intended for educators who teach the arts from early childhood to tertiary level, artists working in the community, or those studying arts in education from undergraduate to Masters or PhD level
Quantifying critical thinking: Development and validation of the Physics Lab Inventory of Critical thinking (PLIC)
Introductory physics lab instruction is undergoing a transformation, with
increasing emphasis on developing experimentation and critical thinking skills.
These changes present a need for standardized assessment instruments to
determine the degree to which students develop these skills through
instructional labs. In this article, we present the development and validation
of the Physics Lab Inventory of Critical thinking (PLIC). We define critical
thinking as the ability to use data and evidence to decide what to trust and
what to do. The PLIC is a 10-question, closed-response assessment that probes
student critical thinking skills in the context of physics experimentation.
Using interviews and data from 5584 students at 29 institutions, we
demonstrate, through qualitative and quantitative means, the validity and
reliability of the instrument at measuring student critical thinking skills.
This establishes a valuable new assessment instrument for instructional labs.Comment: 16 pages, 4 figure
Beyond capitalism and liberal democracy: on the relevance of GDH Cole’s sociological critique and alternative
This article argues for a return to the social thought of the often ignored early 20th-century English thinker GDH Cole. The authors contend that Cole combined a sociological critique of capitalism and liberal democracy with a well-developed alternative in his work on guild socialism bearing particular relevance to advanced capitalist societies. Both of these, with their focus on the limitations on ‘free communal service’ in associations and the inability of capitalism to yield emancipation in either production or consumption, are relevant to social theorists looking to understand, critique and contribute to the subversion of neoliberalism. Therefore, the authors suggest that Cole’s associational sociology, and the invitation it provides to think of formations beyond capitalism and liberal democracy, is a timely and valuable resource which should be returned to
Crystal-Violet Vaccille
For many years, research workers have endeavored to produce a vaccine from the blood of cholera infected pigs. Numerous chemical agents, heat, cold and desiccation have been used in attempts to destroy or attenuate the disease-producing properties of the blood and at the same time preserve its antigenic properties
Measuring the galaxy power spectrum and scale-scale correlations with multiresolution-decomposed covariance -- I. method
We present a method of measuring galaxy power spectrum based on the
multiresolution analysis of the discrete wavelet transformation (DWT). Since
the DWT representation has strong capability of suppressing the off-diagonal
components of the covariance for selfsimilar clustering, the DWT covariance for
popular models of the cold dark matter cosmogony generally is diagonal, or
(scale)-diagonal in the scale range, in which the second scale-scale
correlations are weak. In this range, the DWT covariance gives a lossless
estimation of the power spectrum, which is equal to the corresponding Fourier
power spectrum banded with a logarithmical scaling. In the scale range, in
which the scale-scale correlation is significant, the accuracy of a power
spectrum detection depends on the scale-scale or band-band correlations. This
is, for a precision measurements of the power spectrum, a measurement of the
scale-scale or band-band correlations is needed. We show that the DWT
covariance can be employed to measuring both the band-power spectrum and second
order scale-scale correlation. We also present the DWT algorithm of the binning
and Poisson sampling with real observational data. We show that the alias
effect appeared in usual binning schemes can exactly be eliminated by the DWT
binning. Since Poisson process possesses diagonal covariance in the DWT
representation, the Poisson sampling and selection effects on the power
spectrum and second order scale-scale correlation detection are suppressed into
minimum. Moreover, the effect of the non-Gaussian features of the Poisson
sampling can be calculated in this frame.Comment: AAS Latex file, 44 pages, accepted for publication in Ap
Facts About So-Called Hog Cholera Cures and Specifics
Although many so-called hog cholera cures and specifics are widely advertised, none has been found so far In the tests made by the veterinary section or the Iowa Agricultural Experiment Station which will cure bogs affected with cholera. Furthermore, the only product known at the present time which will Immunize hogs against cholera Is the anti-hog cholera serum produced by the Niles-Dorset method
Quantum entanglement and teleportation in pulsed cavity-optomechanics
Entangling a mechanical oscillator with an optical mode is an enticing and
yet a very challenging goal in cavity optomechanics. Here we consider a pulsed
scheme to create Einstein-Podolsky-Rosen-type entanglement between a
traveling-wave light pulse and a mechanical oscillator. The entanglement can be
verified unambiguously by a pump-probe sequence of pulses. In contrast to
schemes that work in a steady-state regime under a continuous-wave drive, this
protocol is not subject to stability requirements that normally limit the
strength of achievable entanglement. We investigate the protocol's performance
under realistic conditions, including mechanical decoherence, in full detail.
We discuss the relevance of a high mechanical Qf product for entanglement
creation and provide a quantitative statement on which magnitude of the Qf
product is necessary for a successful realization of the scheme. We determine
the optimal parameter regime for its operation and show it to work in current
state-of-the-art systems.Comment: 10 pages, 2 figure

THE MARKET FOR E-COMMERCE SERVICES IN AGRICULTURE
We report results of a survey of 608 Ohio agribusinesses in 1999 and show them to be divided in their attitudes and acceptance of e-commerce. Half of the respondents report that their business has a web site, although many had taken a negative stance toward such a move. Nearly all say that the internet will significantly change their sector, and the majority of managers report that e-commerce has significantly affected the way they view their business.Marketing,
