dissertationAn introduction to Scanning Probe Microscopy is given along with some basic principles in the detection of electron tunneling by Atomic Force Microscopy (AFM) using electrostatic force. Dynamic Tunneling Force Microscopy (DTFM), a new scanned probe force-detected tunneling technique, is presented and described, in which shuttling of electrons between electron trap states and a conductive AFM probe provides a means to image these trap states with subnanometer spatial resolution. The further development of Single Electron Tunneling Force Spectroscopy (SETFS) is described, providing a method to measure the energy of electronic trap states. It is used to find the energy spectrum of individual monolayer-protected gold clusters. A novel technique is presented whereby the electron trap states' depth and energy are independently determined using SETFS. Finally, a new technique is described and explored, by which "single spin" electron spin resonance measurements can in principle be performed. The method employs the detection of magnetic resonance through spin dependent tunneling, providing a means to identify individual paramagnetic electron states in dielectric films with atomic spatial resolution

The CDEP in town and country Arnhem Land: Bawinanga Aboriginal Corporation

This Discussion Paper presents the findings of research undertaken in 2000 on the Community Development Employment Projects (CDEP) scheme administered by the Bawinanga Aboriginal Corporation (BAC). BAC is located in the township of Maningrida in central Arnhem Land, and the CDEP scheme has participants residing both in Maningrida township and at outstations in the hinterland. A feature of the research is the comparative focus on 'town' and 'country'. The primary aim of the research is to assess the net benefits generated by the operation of the scheme in these two contexts. Benefits are defined not only in terms of employment generation, but also more broadly to include social, cultural and other economic benefits. The discussion is couched in terms of current social policy debates that highlight the apparent negative impacts of welfare dependence and especially 'passive' welfare. This case study focuses on a situation where what could be termed 'active' welfare-CDEP scheme participation-has been an important option, and concludes that there is evidence of significant net benefit from the scheme in a range of areas. On balance, the positives of the scheme outweigh the negatives in the Maningrida regional context, but this does not indicate room for complacency: the workings of the scheme can be improved and some recommendations for change are made

Colonialism Continues to Impact the Health and Diet of Native Peoples

The impact of colonialism on First Nations is rarely looked at the through the result of food abuse and health. Institutions like residential schools attempted to disrupt the relationship between Native peoples with food. Food is a central area for community and spiritual life. However, traditional knowledge continues to thrive in new forms of media, including Indigenous food ways and ceremony.York's Knowledge Mobilization Unit provides services and funding for faculty, graduate students, and community organizations seeking to maximize the impact of academic research and expertise on public policy, social programming, and professional practice. It is supported by SSHRC and CIHR grants, and by the Office of the Vice-President Research & Innovation. [email protected] www.researchimpact.c

Improved Bounds on Information Dissemination by Manhattan Random Waypoint Model

With the popularity of portable wireless devices it is important to model and predict how information or contagions spread by natural human mobility -- for understanding the spreading of deadly infectious diseases and for improving delay tolerant communication schemes. Formally, we model this problem by considering $M$ moving agents, where each agent initially carries a \emph{distinct} bit of information. When two agents are at the same location or in close proximity to one another, they share all their information with each other. We would like to know the time it takes until all bits of information reach all agents, called the \textit{flood time}, and how it depends on the way agents move, the size and shape of the network and the number of agents moving in the network. We provide rigorous analysis for the \MRWP model (which takes paths with minimum number of turns), a convenient model used previously to analyze mobile agents, and find that with high probability the flood time is bounded by $O\big(N\log M\lceil(N/M) \log(NM)\rceil\big)$, where $M$ agents move on an $N\times N$ grid. In addition to extensive simulations, we use a data set of taxi trajectories to show that our method can successfully predict flood times in both experimental settings and the real world.Comment: 10 pages, ACM SIGSPATIAL 2018, Seattle, U

Deep Chandra Observations of the Compact Starburst Galaxy Henize 2-10: X-rays from the Massive Black Hole

We present follow-up X-ray observations of the candidate massive black hole (BH) in the nucleus of the low-mass, compact starburst galaxy Henize 2-10. Using new high-resolution observations from the Chandra X-ray Observatory totaling 200 ks in duration, as well as archival Chandra observations from 2001, we demonstrate the presence of a previously unidentified X-ray point source that is spatially coincident with the known nuclear radio source in Henize 2-10 (i.e., the massive BH). We show that the hard X-ray emission previously identified in the 2001 observation is dominated by a source that is distinct from the nucleus, with the properties expected for a high-mass X-ray binary. The X-ray luminosity of the nuclear source suggests the massive BH is radiating significantly below its Eddington limit (~10^-6 L_Edd), and the soft spectrum resembles other weakly accreting massive BHs including Sagittarius A*. Analysis of the X-ray light curve of the nucleus reveals the tentative detection of a ~9-hour periodicity, although additional observations are required to confirm this result. Our study highlights the need for sensitive high-resolution X-ray observations to probe low-level accretion, which is the dominant mode of BH activity throughout the Universe.Comment: Accepted for publication in ApJ Letters. 7 pages, 4 figure
