Tales of science and defiance : the case for co-learning and collaboration in bridging the science/emotion divide in water recycling debates

Although science is generally assumed to be well integrated into rational decision-making models, it can be used to destabilise consultative processes, particularly when emotions are involved. Water policies are often seen as debates over technical and engineering issues, but can be highly controversial. Recycled water proposals, in particular, can create highly emotive conflicts. Through a case study regarding the rejection of recycled water proposals in the south-east Queensland, Australia, we explore the influence of science and emotions in contemporary water planning. We highlight the dangers inherent in promoting technical water planning issues at the expense of appropriate consideration of citizen concerns. Combining the science–policy interface and stakeholder engagement literatures, we advocate for collaborative decision-making processes that accommodate emotions and value judgements. A more collaborative stakeholder engagement model, founded on the principles of co-learning, has the potential to broaden the decision-making base and to promote better and more inclusive decision-making.

Spatial Demultiplexing in the sub-millimeter wave band using multlayer free-standing frequency selective surfaces

In this paper, we show that a multilayer freestanding slot array can be designed to give an insertion loss which is significantly lower than the value obtainable from a conventional dielectric backed printed frequency selective surface (FSS). This increase in filter efficiency is highlighted by comparing the performance of two structures designed to provide frequency selective beamsplitting in the quasioptical feed train of a submillimeter wave space borne radiometer. A two layer substrateless FSS providing more than 20 dB of isolation between the bands 316.5â??325.5 GHz and 349.5â??358.5 GHz, gives an insertion loss of 0.6 dB when the filter is orientated at 45 incidence in the TM plane, whereas the loss exhibited by a conventional printed FSS is in excess of 2 dB. A similar frequency response can be obtained in the TE plane, but here a triple screen structure is required and the conductor loss is shown to be comparable to the absorption loss of a dielectric backed FSS. Experimental devices have been fabricated using a precision micromachining technique. Transmission measurements performed in the range 250â??360 GHz are in good agreement with the simulated spectral performance of the individual periodic screens and the two multilayer freestanding FSS structures.

Henry Hope & Sons of Canada Ltd. Letter, 1916

Henry Hope & Sons of Canada Ltd. were located at 45 King Street West, Toronto, Ont. at the writing of this letter in 1916. The company specialized in “weathertight casements in iron steel or gun-metal, unbreakable steel windows, fanlight opening-gear, leaded lights and stained glass, patent glass roofing, locks and door furniture, rainwater goods in cast lead and cast iron”. The letter is addressed to Mr. H.Y. [Harry Young] Grant, c/o Fenwick Farm, Lundy’s Lane, Niagara Falls, Ont. from R.W. Smith. The letter is in reply to a query about casement windows. Harry Young Grant (1860-1934), son of Sir James Alexander Grant and Maria Malloch of Ottawa, Ont. was a medical doctor specializing in the treatment of the eye, ear, nose and throat. After his retirement he became a member of the Niagara Parks Commission. He was married to Grace A. Smith, daughter of James R. Smith of Buffalo.
