Marine Invertebrates: Communities At Risk, Jennifer A. Mather Jun 2013

Marine Invertebrates: Communities At Risk, Jennifer A. Mather

Ecological Impacts of Climate Change Collection

Our definition of the word ‘animal’ centers on vertebrates, yet 99% of the animals on the planet are invertebrates, about which we know little. In addition, although the Census of Marine Life (COML.org) has recently conducted an extensive audit of marine ecosystems, we still do not understand much about the animals of the seas. Surveys of the best-known ecosystems, in which invertebrate populations often play a key role, show that the invertebrate populations are affected by human impact. Coral animals are the foundation of coral reef systems, which are estimated to contain 30% of the species in the ocean. Physical …


Anomaly Detection On Social Data, Hanbo Dai Jun 2013

Anomaly Detection On Social Data, Hanbo Dai

Dissertations and Theses Collection (Open Access)

The advent of online social media including Facebook, Twitter, Flickr and Youtube has drawn massive attention in recent years. These online platforms generate massive data capturing the behavior of multiple types of human actors as they interact with one another and with resources such as pictures, books and videos. Unfortunately, the openness of these platforms often leaves them highly susceptible to abuse by suspicious entities such as spammers. It therefore becomes increasingly important to automatically identify these suspicious entities and eliminate their threats. We call these suspicious entities anomalies in social data, as they often hold different agenda comparing to …


Demo: Approximate Semantic Matching In The Collider Event Processing Engine, Souleiman Hasan, Kalpa Gunaratna, Yongrui Qin, Edward Curry Jun 2013

Demo: Approximate Semantic Matching In The Collider Event Processing Engine, Souleiman Hasan, Kalpa Gunaratna, Yongrui Qin, Edward Curry

Kno.e.sis Publications

This demo presents a use case from the energy management domain. It builds upon previous work on approximate semantic matching of heterogeneous events and compares two semantic matching scenarios: exact and approximate. It illustrates how a large number of exact matching event subscriptions are needed to match heterogeneous power consumption events. It then demonstrates how a small number of approximate semantic matching subscriptions are needed but possibly with a lower true positives/negatives performance. The demo is delivered via the COLLIDER approximate event processing engine currently under development in DERI.


A Natural Resource Condition Assessment For Sequoia And Kings Canyon National Parks, Appendix 16 - Bats, Alice Chung-Maccoubrey Jun 2013

A Natural Resource Condition Assessment For Sequoia And Kings Canyon National Parks, Appendix 16 - Bats, Alice Chung-Maccoubrey

United States National Park Service: Publications

Scope of Analysis

North American bats are highly unique animals that have historically been overlooked by land managers and misunderstood by the public. Bats are unique as the only true flying mammals and due to their exceptionally long lives (5-15 years) and unusually low reproductive rates (typically one young per year) for their small size. Most North American bat species are insectivorous, serve as the primary predators of nocturnal insects, and can consume up to one-third of their weight in insects per night. Thus, bats play a role in regulating insect populations, insect-related ecological processes, and nutrient redistribution and cycling …

Mapping Human-Environment Connections On The Olympic Peninsula: An Atlas Of Landscape Values, Rebecca J. Mclain, Lee Cerveny, Diane Besser, David Banis, Alexa Todd, Stephanie Rohdy, Corinna Kimball-Brown

Occasional Papers in Geography

Occasional Papers in Geography Publication No. 7

The advent of computerized mapping has land managers’ ability to map the biophysical services provided by forested ecosystems. However, mapping the cultural services of those systems is more challenging. Human ecology mapping (HEM), which provides spatially-explicit depictions of the complex connections between humans and their environment, is an approach that can be used to improve understandings of the cultural services associated with landscapes. This atlas provides an overview of what HEM is and draws on experiences with a pilot project on the Olympic Peninsula in western Washington to illustrate what HEM data looks …


On The Derivation Of Estimators Of Foster-Greer-Thorbecke (Fgt) Poverty Indices, Oyedeji I. Osowole, Adebayo T. Bamiduro Jun 2013

On The Derivation Of Estimators Of Foster-Greer-Thorbecke (Fgt) Poverty Indices, Oyedeji I. Osowole, Adebayo T. Bamiduro

CBN Journal of Applied Statistics (JAS)

Poverty analysis has relied heavily on data in summarized form and this has created dearth of knowledge on the statistical properties of Foster-Greer-Thorbecke (FGT) poverty indices. This study derived estimators of FGT poverty indices from first principles in an attempt to provide an insight into some intrinsic characteristics of FGT indices. The estimators are found to be reasonably unbiased and consistent. The estimates of the indices obtained from the estimators are approximately 53%, 22% and 12% for the head count, poverty gap and square poverty gap indices. From the conventional method, the estimates are approximately 52%, 21% and 11% respectively. …


Measuring Technical Efficiency Of Wireless And Wired Technologies In Nigeria Cyber Cafés, Sule Magaji, Eke I. Chukwuemeka Jun 2013

Measuring Technical Efficiency Of Wireless And Wired Technologies In Nigeria Cyber Cafés, Sule Magaji, Eke I. Chukwuemeka

CBN Journal of Applied Statistics (JAS)

This study examined the technical efficiency (TE) of two different remote internet access methods, wireless and wired in Nigeria using the stochastic frontier production function analysis. Primary data were obtained through the use of a set of questionnaire from four hundred and fifty representative samples of cyber café operators. The results show that in Nigeria, in spite of the acclaimed superiority of wireless technologies internationally, wired technology (within the context of Nigeria’s socio-economic constraints) is (still) more efficient technically with mean technical efficient indices of 0.914 and 0.797 respectively. The analysis also suggests that age and years of education of …


Monetary Policy Rule: A Broad Monetary Conditions Index For Nigeria, Yaaba N. Baba Jun 2013

Monetary Policy Rule: A Broad Monetary Conditions Index For Nigeria, Yaaba N. Baba

CBN Journal of Applied Statistics (JAS)

To determine the relative importance of both the domestic and external influences on monetary policy formulation, this paper constructs a broad monetary conditions index for Nigeria. It brings together the three key channels of monetary transmission, namely interest rate, exchange rate and credit channels. The result gives dominance to exchange rate channel, followed by credit channel and interest rate channel. The resultant monetary conditions index traces fairly well the policy direction of the Central Bank of Nigeria for the studied period, hence can serve as an adequate gauge of monetary policy stance of the Bank.


Effect Of Monetary-Fiscal Policies Interaction On Price And Output Growth In Nigeria, Musa Yakubu, Asar K. Barfour, Shehu U. Gulumbe Jun 2013

Effect Of Monetary-Fiscal Policies Interaction On Price And Output Growth In Nigeria, Musa Yakubu, Asar K. Barfour, Shehu U. Gulumbe

CBN Journal of Applied Statistics (JAS)

This paper investigates the effectiveness of monetary-fiscal policies interaction on price and output growth in Nigeria. The dynamic correlations of variables have been captured by the analyses of impulse response and variance decomposition. From innovation analyses, the results suggest that the policy variables money supply and government revenue have more positive impact on price and economic growth in Nigeria specifically in the long run, thus some time with lag. Although monetary and fiscal policy variables have a dominant effect on economic activity, it is clear from this study that economic activity is dominated by its own dynamics in most of …


The Relationship Between Domestic Savings And Investment: The Feldstein-Horioka Test Using Nigerian Data, Inuwa Nasiru, Usman M. Haruna Jun 2013

The Relationship Between Domestic Savings And Investment: The Feldstein-Horioka Test Using Nigerian Data, Inuwa Nasiru, Usman M. Haruna

CBN Journal of Applied Statistics (JAS)

This study explores the relationship between savings and investment in Nigeria during the period 1980-2011. Unlike previous studies, this study employed Autoregressive Distributed Lag (ARDL) Bounds testing approach to test for long run relationship. The short-run dynamics are also captured from error correction model (ECM).The results of the Bounds test suggest that there is a long run relationship between savings and investment. This result is consistent with a number of earlier studies reviewed in the literature that found saving and investment to be cointegrated in the long run. The results also support the Feldstein-Horioka (1980) hypothesis that postulates low capital …


Exchange–Rates Volatility In Nigeria: Application Of Garch Models With Exogenous Break, Bala A. Dahiru, Joseph O. Asemota Jun 2013

Exchange–Rates Volatility In Nigeria: Application Of Garch Models With Exogenous Break, Bala A. Dahiru, Joseph O. Asemota

CBN Journal of Applied Statistics (JAS)

This paper examines exchange–rate volatility with GARCH models using monthly exchange–rate return series from 1985:1 to 2011:7 for Naira/US dollar return and from 2004:1 to 2011:7 for Naira/British Pounds and Naira/Euro returns. The study compare estimates of variants of GARCH models with break in respect of the US dollar rates with exogenously determined break points. Our results reveal presence of volatility in the three currencies and equally indicate that most of the asymmetric models rejected the existence of a leverage effect except for models with volatility break. Evaluating the models through standard information criteria, volatility persistence and the log likelihood …


The Role Of Central Bank Of Nigeria’S Analytical Balance Sheet And Monetary Survey In Monetary Policy Implementation, Sani I. Doguwa, Sunday N. Essien Jun 2013

The Role Of Central Bank Of Nigeria’S Analytical Balance Sheet And Monetary Survey In Monetary Policy Implementation, Sani I. Doguwa, Sunday N. Essien

CBN Journal of Applied Statistics (JAS)

This paper discusses the significance of Central Bank of Nigeria’s (CBN) monetary aggregates in the implementation of monetary policy. The Analytical Balance Sheet and monetary survey are shown to be useful tools in the analysis of monetary and credit developments in the economy. It also discusses the role of the aggregates in monetary policy implementation through the adjusted money multiplier, which explains how policy actions of the CBN influence the broad money supply. Finally, the paper attempts to estimate the Taylor-type monetary policy reaction function for Nigeria using the monetary policy rate and reserve money since December 2006 when the …


Misheard Me Oronyminator: Using Oronyms To Validate The Correctness Of Frequency Dictionaries, Jennifer G. Hughes Jun 2013

Misheard Me Oronyminator: Using Oronyms To Validate The Correctness Of Frequency Dictionaries, Jennifer G. Hughes

Master's Theses

In the field of speech recognition, an algorithm must learn to tell the difference between "a nice rock" and "a gneiss rock". These identical-sounding phrases are called oronyms. Word frequency dictionaries are often used by speech recognition systems to help resolve phonetic sequences with more than one possible orthographic phrase interpretation, by looking up which oronym of the root phonetic sequence contains the most-common words.

Our paper demonstrates a technique used to validate word frequency dictionary values. We chose to use frequency values from the UNISYN dictionary, which tallies each word on a per-occurance basis, using a proprietary text corpus, …


Urban Agriculture Stormwater Management In California Cities, Rachel L. Cohen Jun 2013

Urban Agriculture Stormwater Management In California Cities, Rachel L. Cohen

Master's Theses

Cities within California are beginning to incorporate urban agriculture into their land use designations. Prompted by residents and local organizations, cities are hoping to capture the benefits that urban agriculture provides. Research has shown that urban agriculture renews and beautifies neighborhoods, provides healthy food choices, increases public health, has the potential to help with stormwater runoff, creates jobs, and fosters community. In the last few years, several California cities have made headlines as they have adopted new zoning codes that include urban agriculture.

In reviewing these new zoning codes and exploring the topic of urban agriculture, it became evident that …


From Scrapbook To Facebook: A History Of Personal Media Assemblage And Archives, Katie Day Good Jun 2013

From Scrapbook To Facebook: A History Of Personal Media Assemblage And Archives, Katie Day Good

University Faculty Publications and Creative Works

This study surveys recent research on print-era scrapbooks and contemporary social media to highlight commonalities between the two formats, both in terms of the practices they have historically promoted for users, and the methodological challenges they produce for researchers. It argues that scrapbooks and social media can be conceptualized as sites of personal media assemblage and personal media archives, a designation that highlights the simultaneously social and archival dimensions of each form. After discussing these formal similarities, the author identifies three shared functions: (1) documenting friendship, (2) navigating new media abundance, and (3) communicating taste and building cultural capital. By …


Real Time Event Detection In Twitter, Xun Wang, Feida Zhu, Jing Jiang, Sujian Li Jun 2013

Real Time Event Detection In Twitter, Xun Wang, Feida Zhu, Jing Jiang, Sujian Li

Research Collection School Of Computing and Information Systems

Event detection has been an important task for a long time. When it comes to Twitter, new problems are presented. Twitter data is a huge temporal data flow with much noise and various kinds of topics. Traditional sophisticated methods with a high computational complexity aren’t designed to handle such data flow efficiently. In this paper, we propose a mixture Gaussian model for bursty word extraction in Twitter and then employ a novel time-dependent HDP model for new topic detection. Our model can grasp new events, the location and the time an event becomes bursty promptly and accurately. Experiments show the …


A Latent Variable Model For Viewpoint Discovery From Threaded Forum Posts, Minghui Qiu, Jing Jiang Jun 2013

A Latent Variable Model For Viewpoint Discovery From Threaded Forum Posts, Minghui Qiu, Jing Jiang

Research Collection School Of Computing and Information Systems

Threaded discussion forums provide an important social media platform. Its rich user generated content has served as an important source of public feedback. To automatically discover the viewpoints or stances on hot issues from forum threads is an important and useful task. In this paper, we propose a novel latent variable model for viewpoint discovery from threaded forum posts. Our model is a principled generative latent variable model which captures three important factors: viewpoint specific topic preference, user identity and user interactions. Evaluation results show that our model clearly outperforms a number of baseline models in terms of both clustering …

Session 4-1-D: The Experience Of Lotto 6/49 And The Capacity To Trust: Elements For An Anthropology Of Gambling, Jocelyn Gadbois May 2013

Session 4-1-D: The Experience Of Lotto 6/49 And The Capacity To Trust: Elements For An Anthropology Of Gambling, Jocelyn Gadbois

International Conference on Gambling & Risk Taking

Anthropologists study Lotto 6/49 as an experience.

Lévy-Bruhl tries to compare the magical beliefs of serious gamblers with the magical beliefs of individuals he refers to as the ‘‘primitives’’ (1924).

After that, Henslin studied the superstitions of St.Louis taxi drivers who play craps during their work breaks and compared them to Skinner’s pigeon (1967).

I wanted in my thesis to help anthropology to reconstruct lost knowledge regarding gambling and beliefs about magic in capitalist society.

Session 3-3-A: The ‘Circles Concept’ Of Gambling Addiction: An Empowered Framework For Change, Harry B. Mayr May 2013

Session 3-3-A: The ‘Circles Concept’ Of Gambling Addiction: An Empowered Framework For Change, Harry B. Mayr

International Conference on Gambling & Risk Taking

The original ‘Circles Concept of (Gambling) Addiction’ was developed by Harry Mayr in 1982, while working as an addictions counsellor in a community-based health centre. It has always been a ‘user friendly’ concept … applicable and understood by people from all cultures, across all ages, and with or without an addiction issue. Years later, people have informed Mr Mayr how they still remember ‘those circles’, and how the concept helped them.

The ‘Circles Concept of (Gambling) Addiction’ is therefore a concept remembered as much for its visual cues as its verbal explanation – and thus applicable across languages, cognitive and …
