Critical Factors Hampering Agricultural Productivity In Ethiopia: The Case Of Northern Ethiopian Farmers, Yezihalem Tesfa Dagnaw

International Conference on African Development Archives

Why we Ethiopians are celebrated for unforgettable images of chronically malnourished children with large skeletal heads clinging to their mothers dried up breasts? Why we are still forced to seek for food aid when there is ample local potential to feed ourselves? Why does drought, famine return almost every decade in Ethiopia? The paper attempts to demonstrate convincingly that Ethiopian droughts and famines are not sudden natural disasters nor are they simply caused by lack of rainfall. It tries to show the weaknesses of successive strategic development related policies intended to reverse the situation which considered and treated natural factors …

Influence Of Credit Constraint On Technical Efficiency Of Farm Households In Southeastern Ethiopia, Hussien Hamda Komicha, Bo Öhlmer

International Conference on African Development Archives

Credit constraint not only affects the purchasing power of farmers to procure farm inputs and cover operating costs in the short run, but also their capacity to make farm-related investments as well as risk behaviour in technology choice and adoption. These, in turn, have influence on technical efficiency of the farmers. Although credit constraint problem has been recognized in economics literature, especially in those dealing with developing countries, little emphasis has been given to its effect on productive efficiency of farmers. In light of this, explicitly considering credit constraint, this paper estimated technical efficiency of credit-constrained (CCFH) and unconstrained farm …

The Contribution Of Farmers’ Breeders In Meeting Food Security: The Case Of Sorghum (Sorghum Bicolor (L.) Moench) In Ethiopia, Firew Mekbib

International Conference on African Development Archives

Sorghum (Sorghum bicolor (L.) Moench) is the fifth most important cereal crop worldwide and it is the third most important crop in Ethiopia. The national average yield amounts 1302 kg/ha. In order to assess the achievement in farmer breeding various types of research were undertaken. These include survey research to quantify the trend in productivity, the level of and reasons for adoption of improved varieties, yield performance and preference evaluation of farmers’ varieties (FVs) and improved varieties (IVs). As per the trend analysis over the last four decades, total production and yield per hectare has increased by 11.63% and …

An Investigation Of The Roles Of Female Publishers Within Illinois Media, Sarah Whitney

Student Honors Theses

This project started during a Women and Mass Media course at Eastern Illinois

University taught by Dr. Sally Turner. The class visited Marion Best, publisher and

owner of The News-Progress in Sullivan, Illinois . From this visit, comes this study.

4

This study found that the number of Illinois female publishers has not quite doubled since 1900 from 34 to 63 . However the percentage of female publishers has skyrocketed from 2 to 19 percent. Three female publishers in Illinois were interviewed about their experiences as women who occupy a position of leadership to gain insight into the challenges of …

Physiological Constraints On Contest Behaviour, Mark Briffa, Lynne U. Sneddon

Sentience Collection

1. Contests may involve injurious fighting, other types of direct physical aggression and communication. They occur over ownership access to mates and other resources that may increase an individual’s attractiveness and its chance of survival. Traits that enhance resource holding potential may be the result of sexual selection, natural selection or a combination of both.
2. Agonistic behaviours are expected to be demanding to perform and costly in terms of changes in physiological state. The ability to meet the physiological costs may determine contest outcomes and constrain the intensity of agonistic activities.
3. The energetic costs have been investigated in a broad range …

The Influence Of Early Experience On, And Inheritance Of, Cerebral Lateralization, Culum Brown, Jac Western, Victoria A. Braithwaite

Veterinary Science and Medicine Collection

Cerebral lateralization refers to the lateralized partitioning of cognitive function in either hemisphere of the brain. Using a standard detour test, we investigated lateralized behaviour in wild-caught, female poeciliid fish, Brachyraphis (=Brachyrhaphis) episcopi, from high- and low-predation areas. Wild fish were bred and their offspring reared under controlled laboratory conditions. These laboratory-reared fish were screened in the same laterality assays as their parents. We observed differences between wild-caught females and their laboratory-reared female offspring in the pattern of lateralization (tendency to use one hemisphere over the other to process information). Conversely, the strength of lateralization (consistency of hemispherical bias) was …

Ethical Issues In Geriatric Feline Medicine, Bernard E. Rollin

Veterinary Science and Medicine Collection

Most veterinarians hold a ‘pediatric’ rather than ‘garage mechanic’ view of their function. In recent years, sophisticated medical modalities have allowed veterinarians to keep animals alive, and increased value of companion animals in society has increased demand for such treatment. But whereas humans can choose to trade current suffering for extended life, animals seem to lack the cognitive apparatus required to do so. Thus, veterinarians must guard against keeping a suffering animal alive for too long. Clients may be emotionally tied to the animal and blind to its suffering. Part of the veterinarian’s role, therefore, is to lead the client …

Nanotechnology Bound: Evaluating The Case For More Regulation, Patrick Lin

Philosophy

In continuing news, there is a growing debate on whether current laws and regulations, both in the US and abroad, need to be strengthened as they relate to nanotechnology. On one side, experts argue that nanomaterials, which are making their way into the marketplace today, are possibly harmful to consumers and the environment, so stronger and new laws are needed to ensure they are safe. On the other side, different experts argue that more regulation will slow down the pace of business and innovation in nanotechnology, or that self-regulation is the answer, or other opposing positions. This paper will draw …

Recombination And Positive Selection Contribute To Evolution Of Listeria Monocytogenes Inla, R. H. Orsi, D. R. Ripoll, M. Yeung, K. K. Nightingale, M. Wiedmann

Biological Sciences

The surface molecule InlA interacts with E-cadherin to promote invasion of Listeria monocytogenes into selected host cells. DNA sequencing of inlA for 40 L. monocytogenes isolates revealed 107 synonymous and 45 nonsynonymous substitutions. A frameshift mutation in a homopolymeric tract encoding part of the InlA signal peptide was identified in three lineage II isolates, which also showed reduced ability to invade human intestinal epithelial cells. Phylogenies showed clear separation of inlA sequences into lineages I and II. Thirteen inlA recombination events, predominantly involving lineage II strains as recipients (12 events), were detected and a number of amino acid residues were …

The 4w Model Of Drowning, Stathis Avramidis, Ronald Butterly, David J. Llewellyn

International Journal of Aquatic Research and Education

The aim of the study was to develop a conceptual model of drowning incidents. The authors conducted qualitative content analysis of drowning-incident videos (n = 41), and semi-structured interviews of those involved in drowning incidents (n = 34), followed by the measurement of frequencies and Boolean search with matrix intersection. Results confirmed that when there is human activity in, above, or around an aquatic environment, a drowning incident may occur to whomever, wherever, and under whatever circumstance. Factors that determined drowning outcome were, in order of importance, rescuer characteristics (Who1), casualty characteristics (Who2), location (Wherever), and general circumstances (Whatever). The …

Florida’S Non-Native Avifauna, Michael L. Avery, Michael P. Moulton

Managing Vertebrate Invasive Species

Florida has a mild climate, diverse natural habitats, and a growing, mobile human population. Florida also hosts thousands of species of introduced plants, fish, and wildlife. A recent compilation lists 196 non-native bird species, comprising 15 orders, which have occurred in Florida. The list includes 72 species of parrots and parakeets (psittaciformes), 51 passerines, and 22 species of waterfowl (anseriformes). First sightings of newly introduced bird species in Florida increased rapidly through the 1980s, but numbers of new species detected appear to have subsided since then. Sources of introductions are often not reported, but of those that are known, most …

Managing Starlings In Australia – Can Drc-1339 Be The Answer?, Tina Bentz, Steven Lapidge, David Dall, Ronald G. Sinclair

Managing Vertebrate Invasive Species

European starlings (Sturnus vulgaris) are one of the most abundant and widespread bird species on earth. Introduced to Australia in the late 1850s, their highly adaptive ecology has enabled them to become a major pest. Concerns include public health and safety, economic impacts, detrimental environmental effects, and bird strikes at airports. Unfortunately current Australian control methods are ineffective and more efficacious, humane methods need to be developed. A feasibility study was undertaken of the likely risks/benefits of avicide DRC 1339 (3-chloro-4-methylbenzenamine hydrochloride) in Australia. This included a risk-analysis, a multi-industry survey and non-toxic bait trials to assess target-specificity. …

Invasive Rats And Bubonic Plague In Northwest Uganda, Jeff N. Borchert, Jeff J. Mach, Timothy J. Linder, Asaph Ogen-Odoi [Deceased, In Memoriam], Santos Angualia

Managing Vertebrate Invasive Species

Major introductions of roof rats (Rattus rattus) likely occurred in the ports of East Africa during the Third Plague Pandemic in the late 1800’s. Transport via trains, boats, and trucking likely introduced this species to inland areas of East Africa, ultimately including Northwest Uganda. Historic plague outbreaks occurred during the early part of the 20th century and continue to cause a human disease burden in the West Nile region of NW Uganda via the bubonic, septicemic, and pneumonic forms. Four field sites in this area were trapped to determine the rodent species composition in commensal and peridomestic areas …

Island Biosecurity As A Pest Management Tactic In New Zealand, Keith Broome

Managing Vertebrate Invasive Species

New Zealand is an archipelago with many islands of conservation significance, none of which has the full suite of invasive vertebrate pests found on mainland New Zealand. Managing invasive species on New Zealand islands involves prevention of pests establishing and controlling or extirpating those already there. Prevention measures, referred to as island biosecurity, focuses on the three major pathways for pests to arrive: deliberate release, accidental release and swimming. Managing deliberate release is largely reactive but does have opportunities for prevention depending on the motivation of offenders. Managing accidental release is where most proactive work is done by Department of …

The Role Of Early Detection And Rapid Response In Thwarting Amphibian And Reptile Introductions In Floridalorida, Todd S. Campbell

Managing Vertebrate Invasive Species

Prevention is the best policy for dealing with introduced species. However, biologists often spend an inordinate amount of time studying their spread and impacts rather than focusing on what should be done to thwart their establishment in the first place. Amphibian and reptile introductions are reaching epidemic proportions in Florida, largely due to irresponsible behavior by pet owners and the pet industry, but also due to ineffective preventive policies and actions. Prevention of additional amphibian and reptile introductions in Florida will require a comprehensive approach involving legal restrictions of certain problematic species, a massive public education effort, and a well-funded …

Can Temperature Be Used As A Tool For Limiting Brown Treesnake Invasion Via Transportation Pathways?, Michelle T. Christy, Julie A. Savidge, Richard Bischof, Gordon H. Rodda

Managing Vertebrate Invasive Species

The use of extreme temperatures is one of the few chemical residue-free techniques available for control of pest species and has proven fast and effective in a variety of applications. We determined the upper and lower lethal temperatures for the brown treesnake. We also investigated whether gender, size, body condition and exposure time influenced survival at temperature extremes. Elevating snake core temperatures to 40°C and 41°C for one hour resulted in 99% mortality within seven days (40°C) and 100% mortality within one hour of exposure (41°C). Mortality decreased sharply to 51% for a one hour exposure to 39°C. Shorter, heavier …
