Momentum
Momentum was an exhibition of work by 8 applied artists who incorporate digital technologies in the creation of their artworks.
The exhibition included 7 original objects created by Illner, using a combination of traditional craft-based and digital technologies such as rapid prototyping and laser engraving, and in materials such as paper, glass and silver. The show took place at Craft in the Bay, which is a leading centre for showcasing new crafts in Wales, with an internationally recognised reputation.
The show travelled to the University of Hertfordshire (UH Galleries), a national centre for the theory of practice-led research (2012/13). An accompanying symposium brought together the artists the issues and themes arising from the use of new technologies within contemporary crafts. Illner's pieces were also shown in Framework Gallery (UH) as part of a group show The Printed Image (2012).
Illner's work for this show was "an enquiry and exploration with materials, processes and techniques." (Dr. Cathy Treadaway, Momentum catalogue) Illner is described as a maker with “a playful and creative approach to materials and forms – these contrasting qualities are fundamental to her way of thinking, making and inspiring others.” (Felicity Cooke, Momentum catalogue).
This work continues Illner's ongoing research project exploring how the digital can be embedded within materials, to create new possibilities in form and technique. Includes collaboration with other craftspeople and technical specialists, in order to develop innovative technical solutions to material connections. Illner’s current research use laser engraving on layered glass to create virtual imagery through shadow and reflection, challenging viewers to reflect on their perception of materials and their visual characteristics.
Illner's practice-led research has also been shown in UK and European galleries over the last 20 years. Her work features in the Crafts Council and other private collections
Community Economic Development Opportunities in Alberta
The Canadian Community Economic Development Network (CCEDNet) and Momentum, a Calgary, Alberta based community economic development (CED) organization, have issued this brief in Alberta. The brief is directed to the Alberta government. The Government of Alberta is committed to investing in job creation, economic diversification, renewable
energy, and being the best place to start and grow a small business. The innovative tools of community economic development (CED) can amplify these economic initiatives by enabling the creation of more social
and co-operative enterprises, providing jobs for disadvantaged Albertans, and advancing community-owned renewable energy. The following three strategies can most benefit Albertans given the current economic
challenges and opportunities in Alberta:
Investing in a Community and Coop Business Secretariat, supported by the Ministry of Economic Development, and hosted at a community based agency. A focus on technical support and connecting businesses to capital and resources.
Providing technical, regulatory, and financial support to community-owned start-ups and projects focused on renewable energy development.
Creating a market exemption for everyday Albertans (unaccredited investors) to invest in local businesses, social enterprises and co-operatives, and ensuring they benefit from the Alberta Investor Tax Credit.Canadian Community Economic Development Network (CCEDNet); Momentum; Alberta Community and Co-operative Association; Athabasca University; Canadian Worker Co-operative Federation; Edmonton Community Foundation; Edmonton Mennonite Centre for Newcomers; REAP - Respect for the Earth and All People; Social Enterprise Fund (Edmonton); and Thrive - Calgary's Community Economic Development Network
Energy-momentum and angular momentum of Goedel universes
We discuss the Einstein energy-momentum complex and the Bergmann-Thomson
angular momentum complex in general relativity and calculate them for
space-time homogeneous Goedel universes. The calculations are performed for a
dust acausal model and for a scalar-field causal model. It is shown that the
Einstein pseudotensor is traceless, not symmetric, the gravitational energy is
"density" is negative and the gravitational Poynting vector vanishes.
Significantly, the total (gravitational and matter) energy "density" fro the
acausal model is zero while for the casual model it is negative.The
Bergmann-Thomson angular momentum complex does not vanish for both G\"odel
models.Comment: an amended version, 24 pages, accepted to PR
Orbital Angular Momentum and Generalized Transverse Momentum Distribution
We show that, when boosted to the infinite momentum frame, the quark and
gluon orbital angular momentum operators defined in the nucleon spin sum rule
of X. S. Chen et al. are the same as those derived from generalized transverse
momentum distributions. This completes the connection between the infinite
momentum limit of each term in that sum rule and experimentally measurable
observables. We also show that these orbital angular momentum operators can be
defined locally, and discuss the strategies of calculating them in lattice QCD.Comment: 8 page
Momentum Equity Strategies: Are Certain Firm-Specific Variables Crucial in Achieving Superior Performance in Short Term Holding Periods?
In this study we analyze the performance of variable-oriented momentum strategies, in order to detect alternatives which offer higher returns, compared to the simple price momentum strategies, for no significantly extra risk, in the very short run. Portfolios are constructed using twenty firm specific variables, of U.S. stocks traded in NYSE, NASDAQ and AMEX for a full six year period starting on March of 2002. We calculate a volatility- reward (VR) ratio for each observation, treated as a performance measure, and we apply Principal Component Analysis (PCA) on their series in order to detect the variables which contribute mostly in enhancing the performance of simple momentum strategies. Our findings suggest that short term investors could significantly benefit from momentum strategies if they take into account past firm specific information, which indirectly indicates a market underreaction to various announcements related to firms' EPS. In particular, top analysts' EPS estimate revisions followed by low P/E and high ROE contribute the most in producing momentum portfolios of superior performance, compared to a simple price momentum strategy. © EuroJournals Publishing, Inc. 2009
