The Making of a Forester
The SUCCESSFUL, happy forester is truly a unique individual. . A deep love for the world of nature, a natural curiosity, and inventiveness, and superior strength of character enable him to tackle the challenging tasks that are always before him. His profession is often beset by conflicting interests, misunderstanding, and the wealth of the well-meaning but ignorant. He does not always line long enough to enjoy all the fruits of his labor. Yet he so strongly believes in the worth of what he is doing that his spirit is never broken
A Suggested Course Of Study For Eighth Grade General Mathematics In Matagorda County Elementary And High Schools
Education of today in public schools is becoming child-conscious, whether it be formal or informal, curricular or extracurricular. Since this is true the writer endeavors to suggest a course of study which is practical for the schools in the particular locality designated in the title of this thesis. Living in a democracy we must strive to reach the masses. One of the major aims of mathematics should be the development in pupils of an appreciation of numbers as a tool. As Dr.Judd points out, one function of mathematics should show the pupil how the number system has enabled the human race to bring order, arrangement, and precision to the consideration of the quantitative aspects of the environment* It is realized more and more that the problem of our schools is one of making mathematics real to the child and not principally one of the teaching processes in mathematics. This is an attempt to give the child the type of mathematics that will help him to make a living if conditions prevent him from continuing in school and to build a good foundation for further study in mathematics. Emphasis shifted from mere skill in manipulation to an understanding of principles and applied problems that are real to the child. Habits of accuracy, neatness end est bating, and checking results should be developed. This thesis is written with the trend of modem education and present-day curriculum in mind
A Qualitative Analysis of Haptic Feedback in Music Focused Exercises
We present the findings of a pilot-study that analysed the role of haptic feedback in a musical context. To examine the role of haptics in Digital Musical Instrument (DMI) design an experiment was formulated to measure the users’ perception of device usability across four separate feedback stages: fully haptic (force and tactile combined), constant force only, vibrotactile only, and no feedback. The study was piloted over extended periods with the intention of exploring the application and integration of DMIs in real-world musical contexts. Applying a music orientated analysis of this type enabled the investigative process to not only take place over a comprehensive period, but allowed for the exploration of DMI integration in everyday compositional practices. As with any investigation that involves creativity, it was important that the participants did not feel rushed or restricted. That is, they were given sufficient time to explore and assess the different feedback types without constraint. This provided an accurate and representational set of qualitative data for validating the participants’ experience with the different feedback types they were presented with
Quantifying methane and nitrous oxide emissions from the UK and Ireland using a national-scale monitoring network
The UK is one of several countries around the world that has enacted legislation to reduce its greenhouse gas emissions. In this study, we present top-down emissions of methane (CH4) and nitrous oxide (N2O) for the UK and Ireland over the period August 2012 to August 2014. These emissions were inferred using measurements from a network of four sites around the two countries. We used a hierarchical Bayesian inverse framework to infer fluxes as well as a set of covariance parameters that describe uncertainties in the system. We inferred average UK total emissions of 2.09 (1.65–2.67) Tg yr−1 CH4 and 0.101 (0.068–0.150) Tg yr−1 N2O and found our derived UK estimates to be generally lower than the a priori emissions, which consisted primarily of anthropogenic sources and with a smaller contribution from natural sources. We used sectoral distributions from the UK National Atmospheric Emissions Inventory (NAEI) to determine whether these discrepancies can be attributed to specific source sectors. Because of the distinct distributions of the two dominant CH4 emissions sectors in the UK, agriculture and waste, we found that the inventory may be overestimated in agricultural CH4 emissions. We found that annual mean N2O emissions were consistent with both the prior and the anthropogenic inventory but we derived a significant seasonal cycle in emissions. This seasonality is likely due to seasonality in fertilizer application and in environmental drivers such as temperature and rainfall, which are not reflected in the annual resolution inventory. Through the hierarchical Bayesian inverse framework, we quantified uncertainty covariance parameters and emphasized their importance for high-resolution emissions estimation. We inferred average model errors of approximately 20 and 0.4 ppb and correlation timescales of 1.0 (0.72–1.43) and 2.6 (1.9–20 3.9) days for CH4 and N2O, respectively. These errors are a combination of transport model errors as well as errors due to unresolved emissions processes in the inventory. We found the largest CH4 errors at the Tacolneston station in eastern England, which may be due to sporadic emissions from landfills and offshore gas in the North Sea
Computing War Narratives
In this text, I will unpack the workings of a particular technological apparatus applied in South Vietnam during the war, contextualising it in the culture of systems-analysis which became prevalent in US defence strategy following the Second World War. This apparatus – called the Hamlet Evaluation System – was in formal operation from 1967 until 1973, and aimed to provide US Forces with a vital narrative of progress in their “pacification programmes” in Vietnam. With its disruptive use of computers, the immense scale and scope of its task, and its affordance of a managerial approach to warfare, this system raises a number of issues around the role of the computer as bureaucratic mediator – in this case, tasked with converting complex insurgencies into legible, systematic narratives. What kind of insights did it provide into the operations of the Vietcong insurgency? How does it fit into the wider ecologies of command and control in the US Military during the first few decades of the Cold War? As the Hamlet Evaluation System, almost fifty years after its inception, is still considered the “gold standard of [counterinsurgency]” (Connable 113), it remains an important case study for those trying to understand how computers structure the institutional bureaucracy of war, and how they are imagined as epistemological tools that can somehow reveal objective truths about the complex, dynamic reality of war
