Sexual Assault Study: Differences by Season

Poster originally presented to the Anchorage Police Department and the 2004 Alaska Summit on Violence Against Women.This issue of Anchorage Community Indicators Series 2, "Sexual Assault Study," describes the spatial patterning and geographical concentration of 541 sexual assaults reported to the Anchorage Police Department in 2000–2001 by season of year: fall (Sep., Oct., Nov.), winter (Dec., Jan., Feb.), spring (Mar., Apr., May), and summer (Jun., Jul., Aug.).This research was supported by Grant No. 2000-RH-CX-K039 awarded by the Bureau of Justice Statistics and by a UAA Faculty Development Grant to the second author.Data / Sexual assault densities by season (maps) / Suspect characteristics (age, race, alcohol use) Victim characteristics (age, race, alcohol use) / Assault characteristics (pick-up location; assault location; relationship

Weight Spectrum of Quasi-Perfect Binary Codes with Distance 4

We consider the weight spectrum of a class of quasi-perfect binary linear codes with code distance 4. For example, extended Hamming code and Panchenko code are the known members of this class. Also, it is known that in many cases Panchenko code has the minimal number of weight 4 codewords. We give exact recursive formulas for the weight spectrum of quasi-perfect codes and their dual codes. As an example of application of the weight spectrum we derive a lower estimate for the conditional probability of correction of erasure patterns of high weights (equal to or greater than code distance).Comment: 5 pages, 11 references, 2 tables; some explanations and detail are adde

Rejection-Cascade of Gaussians: Real-time adaptive background subtraction framework

Background-Foreground classification is a well-studied problem in computer vision. Due to the pixel-wise nature of modeling and processing in the algorithm, it is usually difficult to satisfy real-time constraints. There is a trade-off between the speed (because of model complexity) and accuracy. Inspired by the rejection cascade of Viola-Jones classifier, we decompose the Gaussian Mixture Model (GMM) into an adaptive cascade of Gaussians(CoG). We achieve a good improvement in speed without compromising the accuracy with respect to the baseline GMM model. We demonstrate a speed-up factor of 4-5x and 17 percent average improvement in accuracy over Wallflowers surveillance datasets. The CoG is then demonstrated to over the latent space representation of images of a convolutional variational autoencoder(VAE). We provide initial results over CDW-2014 dataset, which could speed up background subtraction for deep architectures.Comment: Accepted for National Conference on Computer Vision, Pattern Recognition, Image Processing and Graphics (NCVPRIPG 2019

A Limited Dependent Variable Analysis of Integrated Pest Management Adoption in Uganda

In Uganda overall crop loss due to pests exceeds that caused by drought, soil infertility, or poor planting material. Integrated Pest Management (IPM) technologies can reduce pest damage to crops by emphasizing non-chemical control methods thereby reducing potential negative effects of chemicals on the environment while preserving profitability. This study investigates the adoption of eight IPM practices including intercropping, crop rotation, two improved varieties, incorporating an 'exotic weed chaser', optimal planting dates, optimal planting density and fertilizer use. Variables include market forces, social factors, management factors, and technology delivery mechanisms. Results were consistent across the multivariate logit and ordered logit analyses. The single most important category of influential factors across all crops and technologies is economic/market forces, including labor availability, technology resource requirements, technology complexity, and the level of expected benefits. Social factors are generally less associated with IPM technology adoption than either market or institutional factors. Management factors are not important for adoption of the IPM technologies evaluated for the cowpea crop, while with groundnut IPM practices, no social or institutional factors are found to be important. High expected/potential benefits from the groundnut IPM technologies increase the probability of their adoption, as does the availability of off-farm income and farmers' membership in farm organizations. Generally high levels of adoption (>75%) were observed with crop rotation, and improved varieties. Other technologies registered low levels of adoption (<25%), the least popular being the application of fertilizer on sorghum fields.Research and Development/Tech Change/Emerging Technologies,

Harnessing information and communication technologies to leverage scarce resources for cancer education, research and practice in developing countries

In developing countries, low levels of awareness, cost and organizational constraints on access to specialized care contribute to inadequate patient help-seeking behavior. As much as 95% of cancer patients in developing countries are diagnosed at late to end stage disease. Consequently, treatment outcome is dismally poor and a vicious cycle sets in, with public mystification of cancer and the admonishment of cancer medicine as a futile effort, all, to the further detriment of patient help-seeking behavior and treatment engagement. The situation spirals down, when the practice of cancer medicine is not gratifying to the medical practitioner and does not appeal as a medical specialty to those in training. The future of cancer medicine in developing countries thus hinges on the demystification of cancer through positive information, coupled to an effective organization that allows for the optimal use of available resources, facilitates access to specialized care and promotes the flow of knowledge and technology amongst various stakeholders. This paper strives to make a cogent argument and highlight the capital importance of information and communication technologies in organizing and leveraging scarce resources for cancer education, research and practice in developing countries

Theorizing from the Literature: Rural NC African American Males Who Fail to Complete Early College

The African American male dropout rate remains horrific. Educational institutions need to revise their curriculum design and retention strategies. This study examines rural African American males who fail to complete high school using intersectionality and ecological systems theory

“Southern Rights” and Yankee Humor: A Confederate-Federal Jacksonville newspaper

During the War for Southern Independence, Jacksonville was occupied by Federal forces several times for varying periods. On October 5, 1862, the town was seized for the second time, having just been abandoned hurriedly by most of the inhabitants who had not already left their homes earlier in the war

Bioinorganic Chemistry

This book covers material that could be included in a one-quarter or one-semester course in bioinorganic chemistry for graduate students and advanced undergraduate students in chemistry or biochemistry. We believe that such a course should provide students with the background required to follow the research literature in the field. The topics were chosen to represent those areas of bioinorganic chemistry that are mature enough for textbook presentation. Although each chapter presents material at a more advanced level than that of bioinorganic textbooks published previously, the chapters are not specialized review articles. What we have attempted to do in each chapter is to teach the underlying principles of bioinorganic chemistry as well as outlining the state of knowledge in selected areas. We have chosen not to include abbreviated summaries of the inorganic chemistry, biochemistry, and spectroscopy that students may need as background in order to master the material presented. We instead assume that the instructor using this book will assign reading from relevant sources that is appropriate to the background of the students taking the course. For the convenience of the instructors, students, and other readers of this book, we have included an appendix that lists references to reviews of the research literature that we have found to be particularly useful in our courses on bioinorganic chemistry
