The Aid Effectiveness Architecture In Africa: An Analysis Of Aid Structures In Kenya’S Agriculture Sector, Daniel Kipleel Borter Dec 2017

The Aid Effectiveness Architecture In Africa: An Analysis Of Aid Structures In Kenya’S Agriculture Sector, Daniel Kipleel Borter

International Journal of African Development

This study examines in detail the development aid architecture in Kenya’s agriculture sector. The focus is on the mechanisms in place within the Kenyan government (and ministry of agriculture in particular), mechanisms among and within donor agencies, and overall coordination mechanisms that bring together the donors and the government. Findings show that coordination and harmonization activities among donors are yet to yield the desired outcomes such as the division of labor protocol and joint programming. Weaknesses are also observed on the government side where it appears authorities are yet to internalize PD concepts and interpret them to suit the country's …


Impact Of Automated Guidance For Mechanical Control Of Herbicide-Resistant Weeds In Corn, Terry Griffin, James M. Lowenberg-Deboer Oct 2017

Impact Of Automated Guidance For Mechanical Control Of Herbicide-Resistant Weeds In Corn, Terry Griffin, James M. Lowenberg-Deboer

Journal of Applied Farm Economics

This study evaluated the feasibility of reintroducing mechanical weed control as an alternative for herbicide-resistance weed infestations. The production practice tested included row cultivation with a separate banded spray application using high-accuracy automated guidance systems. A range of ground speeds were tested for the row cultivation operation, each with a different per acre cost and timeliness penalty. A typical eastern Corn Belt farm with a rotation of corn and soybean served as the base for the linear programming model. It was found that if the farmer was willing to reintroduce tillage, row cultivation conducted at higher operating speeds in conjunction …


Do Profitable Farms Remain Profitable? Transition Probabilities Using Markov Switching Models Applied To Kansas Farm Data, Jayce S. Stabel, Terry Griffin, Greg Ibendahl Oct 2017

Do Profitable Farms Remain Profitable? Transition Probabilities Using Markov Switching Models Applied To Kansas Farm Data, Jayce S. Stabel, Terry Griffin, Greg Ibendahl

Journal of Applied Farm Economics

Financial vulnerability has been observed across agricultural production regions; however, uncertainty regarding farms’ persistence within specific profitability categories exists. This study compared farm characteristics that persist in most and least profitable categories and then evaluated the probability that farms transitioned among profitability categories. Using 425 Kansas Farm Management Association (KFMA) farms that were present for the 20-year period 1994–2013, the persistence of remaining or transitioning to another profitability category was tested. Specifically, Markov transition probabilities were estimated for Kansas and the six regional KFMA regions. Comparisons of farms that persist in the highest and lowest profitability categories revealed no dramatic …


Application Of The Adjusted Weak Axiom Of Profit Maximization To New Zealand Dairy Farming, Anne E. Dooley, Nicola M. Shadbolt, Koohyar Khatami, Loren W. Tauer Oct 2017

Application Of The Adjusted Weak Axiom Of Profit Maximization To New Zealand Dairy Farming, Anne E. Dooley, Nicola M. Shadbolt, Koohyar Khatami, Loren W. Tauer

Journal of Applied Farm Economics

The weak axiom of profit maximization is a nonparametric, empirical approach that has been used in the United States to analyze dairy farmers’ production and profit behavior under input and output price changes to determine whether farmers effectively respond to these changes. The expectation is that profit calculated using the current year’s input and output combination will be greater than that calculated from the previous year’s combination with current prices more often than due to chance. This approach was replicated using New Zealand dairy farm data (1,785 pairs of records over five years). Current year’s profits were significantly greater in …

The Potential Impact Of Heir Property On Timber Management In The Southeastern United States, Becky Barlow, Conner Bailey Sep 2017

The Potential Impact Of Heir Property On Timber Management In The Southeastern United States, Becky Barlow, Conner Bailey

Professional Agricultural Workers Journal

Abstract

Active timberland management maintains forest health and productivity, which in turn contributes to the sustainability of the resource and wealth of the landowner. However, when land is held as heir property, options for timberland management are often limited. Heir property is owned as an undivided interest among many heirs of an original owner, or multiple generations of owners, who died intestate. This is common among African American landowners in the South. As a result the title is considered “clouded,” limiting access to capital and resources that are beneficial to timberland management. In this paper, the authors hope to improve …

The approach of this research paper is using data from the National Climatic Data Center that focuses in on the weather found in Manhattan, New York and correlates each of the weather conditions to the total number of trips per day that is provided by the Citi …


The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney Jul 2017

The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney

Journal of Environmental and Resource Economics at Colby

Prior studies have expressed the value of location in real estate, but more recent studies have explored the influence that public transportation has had on housing prices. Access to public transportation is understood to increase the value of homes. Easier access to public transportation allows for shorter and more convenient commutes into or within cities. However, other studies have found that proximity to public transportation can also have adverse effects on property values. This paper investigates whether the implementation of the Greenbush Commuter line in Massachusetts in October 2007 increased the housing prices in Scituate, Ma--the furthest town from the …

Effect Of Red Cabbage Extract On Minced Nile Perch Fish Patties Vacuum Packaged In High And Low Oxygen Barrier Films, Ayse Demirbas, Yavuz Yagiz, Ziynet Boz, Bruce A. Welt, Eric Mclamore, Maurice Marshall, William Pelletier, Amarat Simonne

Journal of Applied Packaging Research

Oxidation of polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in fish causes loss of product quality. Oxidative rancidity causes loss of nutritional value and undesirable color changes. Therefore, powerful antioxidant extracts may provide a relatively low cost and natural means to reduce oxidation, resulting in longer, higher quality and higher value shelf life of foods.

In this study, we measured synergistic effects of red cabbage antioxidant and vacuum packaging on lipid oxidation in fresh tilapia patties using thiobarbituric acid reactive substances (TBARS) assay, peroxide value (PV), pH and color analysis.

Concentrated red cabbage extract was obtained …

Succession Planning And Perceived Obstacles And Attractions For Future Generations Entering Beef Cattle Production, Lee L. Schulz, Georgeanne M. Artz, Patrick J. Gunn

Journal of Applied Farm Economics

This study provides valuable insights into cow-calf producer and feedlot operator succession plans for transferring cattle operations upon exiting the industry. Across both cow-calf producers and feedlot operators, about 50% expect to be raising cattle for 10 more years or less; however, about 39% of these producers do not have a succession plan in place. Cow-calf producers view a rural lifestyle, self-employment, working with livestock, and working with family as the biggest attractions to future generations entering beef cattle production. Cow-calf producers view environmental regulations, land tax policy, and expansion of corn and soybean acres as the biggest obstacles. Feedlot …
