Camping in clearcuts: the impacts of timber harvesting on USFS campground utilization

Includes bibliographical references.2022 Fall.The United States Forest Service (USFS) governs its lands under multiple-use management, where land is managed for more than one purpose or objective to achieve the greatest possible combination of public benefits. Some objectives are compatible, while others are not (Clawson, 1974; Rose and Chapman, 2003; USFS, 2021c). This research seeks to inform the site location of future timber harvests relative to existing campgrounds by analyzing how past and current harvests near campgrounds have influenced campground utilization. Beyond this, the research also informs the expected impacts of timber harvesting and recreation on local economies. Previous economic research related to timber harvesting's impact on nearby recreation has been carried out at a smaller spatial scale or outside the U.S., and none have focused on campgrounds specifically (Eggers et al., 2018; Harshaw and Sheppard, 2013). Past studies find that intensive forest management changes the degree of naturalness of a forest and generally negatively impacts recreation. The research we conduct builds on these studies to apply a temporally and spatially explicit model to analyze harvesting's impact on campground utilization on USFS land across the Western U.S. We find that timber harvests significantly decrease reservations during the year of harvest. Furthermore, the selection method of harvest has the most negative impact, likely due to being the most common harvesting method both overall and near campgrounds. There are regional differences in campground demand during harvesting. Additionally, there is evidence to suggest that campground reservations continue to be impacted one year after a harvest takes place. The loss in campground utilization from the reduction in reservations during harvest years can be expected to have negative impacts on nearby tourism-dependent economies

Application of data envelopment analysis to measure technical efficiency on a sample of Irish dairy farms

peer-reviewedThe aim of this study was to determine the levels of technical efficiency on a sample of Irish dairy farms utilizing Data Envelopment Analysis (DEA) and to identify key management and production factors that differ between producers indentified as efficient and inefficient. DEA was used in this study to generate technical efficiency scores under assumptions of both constant returns to scale (CRS) and variable returns to scale (VRS). The average technical efficiency score was 0.785 under CRS and 0.833 under VRS. Key production characteristics of efficient and inefficient producers were compared using an analysis of variance. More technically efficient producers used less input per unit of output, had higher production per cow and per hectare and had a longer grazing season, a higher milk quality standard, were more likely to have participated in milk recording and had greater land quality compared to the inefficient producers

I Like Reading, but I Like Reading what I Like : A White Teacher\u27s Autoethnographic Journey into the Literacy Lives of Black Female Adolescent Readers

When the English teachers at Creswell High School were presented with data that exposed their students’ of color underachievement per English Language Arts standardized state test scores, the teachers were tasked with creating a literacy initiative to increase students’ performance. Using Action Research and Autoethnographic methods, this study seeks to explore Black students’ perceptions of Creswell Reads, a ‘one book, one school’ summer reading program, along with their personal literacy identities both in and out of school. I helped to implement this literacy program before I realized that many American classrooms, including mine, were ostracizing students of color yet wondering why these same students were underachieving per standardized test scores. As a result, this inquiry also parallels my racial awakening to the exploration of how to make a local school’s literacy initiative—one I had a hand in making—more student centered and racially conscious and to present those findings to Creswell High School’s literacy team

The Disappearing State Corporate Income Tax

This paper examines alternative explanations for the decline over the past two decades in state corporate income taxes relative to the state economy. We employ a survey of state tax administrators, individual tax returns from Georgia and Utah, and panel data to explore the importance of tax policy, tax planning, and economic factors on the trend in state corporate taxes. We find that corporate tax planning and economic factors account for much of the relative decline and that state tax policy changes are important factors. However, federal tax changes had only a modest effect during this period. Working Paper 06-2

Understanding the Student Perspective of Art History Survey Course Outcomes Through Game Development

This heuristic, design-based research study examines student perceptions of their learning experience in the art history survey course as manifested through a game design process. With the purpose of improving upon the lecture model of the standard art history survey, two sections of a capstone class of interdisciplinary art and design students—who had all taken the survey as part of their degree programs—selected learning objectives and designed games to accompany the introductory class. The researchers used the game design process to understand first how students perceived the survey class, its learning objectives, and the students’ experiences. Then the investigation addressed how these students designed games to aid learning of survey materials. The results offer survey course instructors significant insight into student perceptions of the structure and aims of art history’s foundational class

Estimation of flattening coefficient for absorption and circular dichroism using simulation

The absorbance and circular dichroism (CD) of suspensions is lower than if the same amount of chromophore were uniformly distributed throughout the medium. Several mathematical treatments of this absorption flattening phenomenon have been presented using various assumptions and approximations. This article demonstrates an alternative simulation approach that allows relaxation of assumptions. On current desktop computers, the algorithm runs quickly with enough particles and light paths considered to get answers that are usually accurate to better than 3%. Results from the simulation agree with the most popular analytical model for 0.01 volume fraction of particles, showing that the extent of flattening depends mainly on the absorbance through a particle diameter. Unlike previous models, the simulation can show that flattening is significantly lower when volume fraction increases to 0.1 but is higher when the particles have a size distribution. The simulation can predict the slope of the nearly linear relationship between flattening of CD and the absorbance of the suspension. This provides a method to correct experimental CD data where volume fraction and particle size are known
