Making Memories: Why Time Matters

In the last decade advances in human neuroscience have identified the critical importance of time in creating long-term memories. Circadian neuroscience has established biological time functions via cellular clocks regulated by photosensitive retinal ganglion cells and the suprachiasmatic nuclei. Individuals have different circadian clocks depending on their chronotypes that vary with genetic, age, and sex. In contrast, social time is determined by time zones, daylight savings time, and education and employment hours. Social time and circadian time differences can lead to circadian desynchronization, sleep deprivation, health problems, and poor cognitive performance. Synchronizing social time to circadian biology leads to better health and learning, as demonstrated in adolescent education. In-day making memories of complex bodies of structured information in education is organized in social time and uses many different learning techniques. Research in the neuroscience of long-term memory (LTM) has demonstrated in-day time spaced learning patterns of three repetitions of information separated by two rest periods are effective in making memories in mammals and humans. This time pattern is based on the intracellular processes required in synaptic plasticity. Circadian desynchronization, sleep deprivation, and memory consolidation in sleep are less well-understood, though there has been considerable progress in neuroscience research in the last decade. The interplay of circadian, in-day and sleep neuroscience research are creating an understanding of making memories in the first 24-h that has already led to interventions that can improve health and learning

Australian Residential Solar Feed-in Tariffs: Industry Stimulus or Regressive Form of Taxation?

Feed-in Tariffs (FiT) for residential photovoltaic solar technologies are available in most Australian jurisdictions. Financial incentives under FiT are in addition to those provided by the Small-Scale Renewable Energy Scheme which forms part of the national 20% Renewable Energy Target. Little attention has been paid to the welfare impacts of FiT on retail electricity prices and social policy objectives. Our analysis indicates that current FiT are a regressive form of taxation. By providing estimates of household impact by income groupings, we conclude that wealthier households are beneficiaries and the effective taxation rate for low income households is three times higher than that paid by the wealthiest households.Feed-in Tariffs, Electricity Prices

Cold Hard Facts

COLD HARD FACTS is an ephemeral installation composed of a projector, digital images and ice. The work continues my interest in having the viewer slow down to have a more thoughtful and absorptive experience with the work and surrounding space. With a short-lived duration, the piece considers the transitory nature of things and how truths can be misconstrued as facts, whereas truths are malleable and facts are not. They are cold, hard and indifferent

Passing

Passing is a Site-specific public installation assembled with plastic and an iPad. At its center, the iPad displays a video loop of a human image repeatedly walking in and out of the frame. The work maintains my foundational interest in having the viewer slow down to have a more thoughtful and absorptive experience with the work and surrounding space – continuing my practice of challenging viewer’s expectations and putting them in a position to stop and question

Light Leaf: Observations of Leaves in Light

For me, spending time in isolation yielded some interesting findings, as I began to closely observe the various leaves that engulf my backyard. Every new day brought with it a new detail, a subtlety with every shift in light, revealing an endless array of abstractions, textures and colors. I was seeing the hidden life of leaves dancing in the sunlight. Naturally, I began documenting my observations

Nickel-Mediated Hydrogenolysis of C–O Bonds of Aryl Ethers: What Is the Source of the Hydrogen?

Mechanistic studies of the hydrogenolysis of aryl ethers by nickel were undertaken with (diphosphine)aryl methyl ethers. A Ni(0) complex containing Ni–arene interactions adjacent to the aryl–O bond was isolated. Heating led to aryl–O bond activation and generation of a nickel aryl methoxide complex. Formal β-H elimination from this species produced a nickel aryl hydride which can undergo reductive elimination in the presence of formaldehyde to generate a carbon monoxide adduct of Ni(0). The reported complexes map out a plausible mechanism of aryl ether hydrogenolysis catalyzed by nickel. Investigations of a previously reported catalytic system using isotopically labeled substrates are consistent with the mechanism proposed in the stoichiometric system, involving β-H elimination from a nickel alkoxide rather than cleavage of the Ni–O bond by H_2
