Perceptions Of Forest Change In The Governmental Region Of Kaffrine, Senegal, Rhiley E. Allbee Jan 2019

Perceptions Of Forest Change In The Governmental Region Of Kaffrine, Senegal, Rhiley E. Allbee

Dissertations, Master's Theses and Master's Reports

Sénégal is a semi-arid West African country with a diverse ethnic makeup and a rapidly growing population that is largely rural, predominantly employed within the agricultural sector, and heavily reliant on the harvesting of forest products within state owned forests where populations have usufruct rights. The country experienced significant changes in land cover throughout the 20th century due to a series of major droughts and large expansions in agriculture. These changes were partially concentrated throughout the region of Kaffrine, where the wooded savannas of the early 20th century were systematically replaced by agriculture and converted to a shrub …


Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims Nov 2017

Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This article presents a new method for estimating changes in depth to groundwater at a yearly, county level and incorporates these estimates as the dependent variable of econometric models for the High Plains aquifer. The High Plains (Ogallala) aquifer underlies eight states in the central United States and is the primary source of irrigation water for this large food producing region. The stock of groundwater is a finite, non-renewable resource with minimal recharge in most areas. Many fields of study, including hydrology and agricultural economics, are interested in depth to groundwater changes because they serve as a proxy for estimating …

Climate Change In The Dead Heart Of Australia, Joshua Larsen, Gerald C. Nanson, Timothy J. Cohen, Brian G. Jones, John D. Jansen, Jan-Hendrik May Dec 2015

Climate Change In The Dead Heart Of Australia, Joshua Larsen, Gerald C. Nanson, Timothy J. Cohen, Brian G. Jones, John D. Jansen, Jan-Hendrik May

Timothy Cohen

Despite the absence of large-scale glaciation, the Australian continent has experienced substantial environmental change throughout the Quaternary period. This is especially pronounced in central Australia, where one seventh of the continent is drained internally to the depocentre, and lowest point in Australia, Lake Eyre (Figure 1). Research has shown that at one time, large sandy braided and meandering rivers carried water through dunefields to a large freshwater lake system. Today, the rivers are hostage to the dunefield, and floodwaters might only reach Lake Eyre once every ten years or so. In order to understand the development of this arid desert …

Meteorological Modes Of Variability For Fine Particulate Matter (Pm2.5) Air Quality In The United States: Implications For Pm2.5 Sensitivity To Climate Change, A. P K. Tai, L J. Mickley, D J. Jacob, E M. Leibensperger, L Zhang, J A. Fisher, H. O T. Pye

Jenny A Fisher

We applied a multiple linear regression model to understand the relationships of PM2.5 with meteorological variables in the contiguous US and from there to infer the sensitivity of PM2.5 to climate change. We used 2004–2008 PM2.5 observations from ~1000 sites (~200 sites for PM2.5 components) and compared to results from the GEOS-Chem chemical transport model (CTM). All data were deseasonalized to focus on synoptic-scale correlations. We find strong positive correlations of PM2.5 components with temperature in most of the US, except for nitrate in the Southeast where the correlation is negative. Relative humidity (RH) is generally positively correlated with sulfate …

Negotiating Change: Working With Children And Their Employers To Transform Child Domestic Work In Iringa, Tanzania, Natascha Klocker

Natascha Klocker

This paper documents the practical and action-oriented findings of an investigation into child domestic work undertaken in Iringa, Tanzania from 2005 to 2007. It provides an overview of the experiences of both child domestic workers and their employers, before discussing their suggestions for how child domestic working arrangements may be improved. The latter sections of the paper relate the attempts to regulate child domestic work that emerged from such dialogue. In providing detailed information on that process, the paper is positioned within the field of action research and resists the boundary frequently applied between academia and activism. It also moves …

Aeolian-Fluvial Interaction: Evidence For Late Quaternary Channel Change And Wind-Rift Linear Dune Formation In The Northwestern Simpson Desert, Australia, Gerald C. Nanson, Brian G. Jones, David M. Price, Tim Pietsch, C Bristow, Cameron B. Hollands Jun 2013

Aeolian-Fluvial Interaction: Evidence For Late Quaternary Channel Change And Wind-Rift Linear Dune Formation In The Northwestern Simpson Desert, Australia, Gerald C. Nanson, Brian G. Jones, David M. Price, Tim Pietsch, C Bristow, Cameron B. Hollands

B. G. Jones

In central Australia the most easterly extent of the MacDonnell Ranges borders the northwestern Simpson Desert where widely spaced strike ridges intercept the regional linear dunefield. Topographic basins have disrupted regional drainage lines and isolated dune sets from the main dunefield. In the western part of Camel Flat basin large, red coloured linear dunes of fine sand, ~ 74 ka and older, are oriented almost due north. Through gaps in the ranges the Todd River traversed the eastern part of the basin until ~25 ka when it apparently avulsed ~25 km eastwards to its present position. Subsequently, linear dunes, smaller, …

The Sedimentary Record Of Palaeoenvironments And Sea-Level Change In The Gulf Of Carpentaria, Australia, Through The Last Glacial Cycle, Jessica Reeves, Allan Chivas, Adriana Garcia, Sabine Holt, Martine Couapel, Brian Jones, Dionisio Cendon, David Fink

B. G. Jones

Environmental evolution of the Gulf of Carpentaria region, the world's largest tropical epicontinental seaway, through the last glacial cycle has been determined from a series of six sediment cores. These cores form the focus of a multi-disciplinary study to elucidate sea level, climate and environmental change in the region. The sedimentary record reveals a series of facies including open shallow marine, marginal marine, estuarine, lacustrine and subaerial exposure, throughout the extent of the basin during this period. The partial or complete closure of the central basin from marine waters results from sea level falling below the height of one or …

Response Of Coral Reefs To Climate Change: Expansion And Demise Of The Southernmost Pacific Coral Reef, Colin D. Woodroffe, Brendan P. Brooke, Michelle Linklater, David M. Kennedy, Brian G. Jones, Cameron Buchanan, Richard Mleczko, Quan Hua, Jian-Xin Zhao Jun 2013

Response Of Coral Reefs To Climate Change: Expansion And Demise Of The Southernmost Pacific Coral Reef, Colin D. Woodroffe, Brendan P. Brooke, Michelle Linklater, David M. Kennedy, Brian G. Jones, Cameron Buchanan, Richard Mleczko, Quan Hua, Jian-Xin Zhao

B. G. Jones

Coral reefs track sea level and are particularly sensitive to changes in climate. Reefs are threatened by global warming, with many experiencing increased coral bleaching. Warmer sea surface temperatures might enable reef expansion into mid latitudes. Here we report multibeam sonar and coring that reveal an extensive relict coral reef around Lord Howe Island, which is fringed by the southernmost reef in the Pacific Ocean. The relict reef, in water depths of 25-50 m, flourished in early Holocene and covered an area more than 20 times larger than the modern reef. Radiocarbon and uranium-series dating indicates that corals grew between …

Bryophyte Species Composition Over Moisture Gradients In The Windmill Islands, East Antarctica: Development Of A Baseline For Monitoring Climate Change Impacts, J Wasley, S A. Robinson, J D. Turnbull, D H. King, W Wanek, M Popp

Sharon Robinson

Extreme environmental conditions prevail on the Antarctic continent and limit plant diversity to cryptogamic communities, dominated by bryophytes and lichens. Even small abiotic shifts, associated with climate change, are likely to have pronounced impacts on these communities that currently exist at their physiological limit of survival. Changes to moisture availability, due to precipitation shifts or alterations to permanent snow reserves, will most likely cause greatest impact. In order to establish a baseline for determining the effect of climate change on continental Antarctic terrestrial communities and to better understand bryophyte species distributions in relation to moisture in a floristically important Antarctic …

Case Study On The Pattern Change In Arabidopsis Thaliana Intron Sequence, Ren Zhang, Rachel Caldwell, Yan-Xia Lin, Jinda Kongcharoen, Yiren Yang

Associate Professor Yan-Xia Lin

A large portion in eukaryotic genomes is introns but their function is not yet fully elucidated. The aims of this study are to employ the generalized Bernoulli modeling approach to estimate the change points based on GC distribution in intron sequences of Arabidopsis thaliana and to investigate whether there is any correlation between gene properties (the gene expression level and the protein function) and these intron pattern changes. The influence of the intron length and the number of GC on the intron sequence pattern changes is demonstrated. Among the random sampled intron sequences, 10.71% have been identified to have pattern …

The Analysis Of Pattern Change In Intron Sequences, Jinda Kongcharoen, Yan-Xia Lin, Rachel Caldwell, Yiren Yang, Ren Zhang

Associate Professor Yan-Xia Lin

The Generalized Bernoulli Modeling approach is used to analyze the pattern change in intron sequences of a model plant species Arabidopsis thaliana. The influence of the intron length and the number of GC on the intron sequence pattern changes is examined. Two other gene properties, the gene expression level and the protein function encoded are also assessed. Among the random sampled intron sequences,10.71% of them have been identified to have sequence pattern change. Our study shows that the number of GC and the intron length significantly influence the intron pattern change while the gene expression level and the protein function …

Differential Expression Of Hypothalamic Cart Mrna In Response To Body Weight Change Following Different Dietary Interventions, Yinghua Yu, Timothy South, Qing Wang, Xu-Feng Huang

Xu-Feng Huang

Cocaine- and amphetamine-regulated transcript (CART) peptide is widely expressed in the hypothalamus and is involved in the central regulation of energy balance. Using in situ hybridization, this study examined the roles of CART peptide in the hypothalamus of diet-induced obese (DIO) or dietresistant (DR) mice under different dietary interventions including high-fat (HF), low-fat (LF) and pairfeeding (PF) diet for 6 weeks. Pair feeding the energy intake of the DIO and DR mice was used to determine whether there is an inherent difference in baseline CART expression that may cause the DIO and DR phenotypes. The results demonstrated that CART mRNA …

Radiocarbon Bomb Spike Reveals Biological Effects Of Antarctic Climate Change, Laurence J Clarke, Sharon A. Robinson, Quan Hua, David J. Ayre, David Fink Aug 2012

Radiocarbon Bomb Spike Reveals Biological Effects Of Antarctic Climate Change, Laurence J Clarke, Sharon A. Robinson, Quan Hua, David J. Ayre, David Fink

Sharon Robinson

The Antarctic has experienced major changes in temperature, wind speed and stratospheric ozone levels during thelast 50 years. However, until recently continental Antarctica appeared to be little impacted by climate warming, thusbiological changes were predicted to be relatively slow. Detecting the biological effects of Antarctic climate changehas been hindered by the paucity of long-term data sets, particularly for organisms that have been exposed to thesechanges throughout their lives. We show that radiocarbon signals are preserved along shoots of the dominant Antarcticmoss flora and use these to determine accurate growth rates over a period of several decades, allowing us toexplore the …


Calculating Clinically Significant Change: Applications Of The Clinical Global Impressions (Cgi) Scale To Evaluate Client Outcomes In Private Practice, Peter Kelly Jul 2012

Calculating Clinically Significant Change: Applications Of The Clinical Global Impressions (Cgi) Scale To Evaluate Client Outcomes In Private Practice, Peter Kelly

Peter Kelly

The Clinical Global Impressions (CGI) scale is a therapist-rated measure of client outcome that has been widely used within the research literature. The current study aimed to develop reliable and clinically significant change indices for the CGI, and to demonstrate its application in private psychological practice. Following the guidelines developed by Clement, a file review was conducted of the authors’ first six years working in private practice. A reliable change on the CGI required the participants score to change by 2-points. Depending on the method used to calculate the clinical change indices, between 23% and 50% of the total participants …
