Canopy Rainfall Interception Measured Over 10 Years in a Coastal Plain Loblolly Pine
CANOPY RAINFALL INTERCEPTION MEASURED OVER TEN YEARS IN A COASTAL PLAIN LOBLOLLY PINE (PINUS TAEDA L.) PLANTATION M. J. Gavazzi, G. Sun, S. G. McNulty, E. A. Treasure, M. G. Wightman ABSTRACT. The area of planted pine in the southern U.S. is predicted to increase by over 70% by 2060, potentially alter- ing the natural hydrologic cycle and water balance at multiple scales. To better account for potential shifts in water yield, land managers and resource planners must accurately quantify water budgets from the stand to the regional scale. The amount of precipitation as rainfall intercepted by forest canopies is an important component of evapotranspiration in for- ested ecosystems, yet there is little information about intra- and inter-annual canopy interception variability in southern pine plantations. To address this knowledge gap, canopy rainfall interception was measured between 2005 and 2014 in a North Carolina coastal plain loblolly pine (Pinus taeda L.) plantation to quantify the range of annual and seasonal varia- bility in interception rates (IRs) as influenced by stand thinning and natural variation in rainfall rates and intensities. Over the study period, biweekly measured canopy IRs averaged 19% across all years, with a range of 14% to 23%. How- ever, at the annual scale, IRs averaged 12% and ranged from 2% to 17%. Thinning resulted in a 5% decrease in rainfall interception, but IRs quickly returned to pre-thin levels. Across years, the amount of annual rainfall intercepted by the canopy averaged 15% of total evapotranspiration, with a range of 2% to 24%. The decade-long data indicate that inter- annual variability of canopy interception is higher than reported in short-term studies. -

Excellence with Equity: It’S Everybody’S Business Findings and Recommendations from the Achievement Gap Study Group
Excellence with Equity: It’s Everybody’s Business Findings and Recommendations from the Achievement Gap Study Group July 2016 Foreword What an honor it has been to work alongside such a dedicated group of educators. Our focus has been on ensuring the highest quality of education for every child in the Commonwealth. We can close the achievement gap if we are willing to consistently implement strategies that are backed by empirical data starting with the removal of stereotypical barriers that inflict adults and affect our children. Frederick Douglass has sagaciously suggested that, “It is easier to build strong children than it is to repair broken adults” (paraphrased). For that reason, this committee has put great emphasis on early childhood education to establish essential building blocks as a solid foundation for the installation of interlocking levels of knowledge critical to assuring that our children can successfully navigate the educational maze that holds the key to their future and ours. If we as policymakers and power brokers are not intentional Dedication about the origination of the solution to the present educational devastation that is devouring us, we will not be successful in steering our children to an intellectual This report is dedicated in destination that will lift the next generation to the heights we collectively aspire. memory of Lynda Thomas. A long-time Prichard This report rebukes the need for further study of what we should do and challenges Committee member all who are strategically positioned to make a difference by doing what we already and leader at Kentucky know.

A Note on the Screaming Toes Game
A note on the Screaming Toes game Simon Tavar´e1 1Department of Statistics, Columbia University, 1255 Amsterdam Avenue, New York, NY 10027, USA June 11, 2020 Abstract We investigate properties of random mappings whose core is composed of derangements as opposed to permutations. Such mappings arise as the natural framework to study the Screaming Toes game described, for example, by Peter Cameron. This mapping differs from the classical case primarily in the behaviour of the small components, and a number of explicit results are provided to illustrate these differences. Keywords: Random mappings, derangements, Poisson approximation, Poisson-Dirichlet distribu- tion, probabilistic combinatorics, simulation, component sizes, cycle sizes MSC: 60C05,60J10,65C05, 65C40 1 Introduction The following problem comes from Peter Cameron’s book, [4, p. 154]. n people stand in a circle. Each player looks down at someone else’s feet (i.e., not at their own feet). At a given signal, everyone looks up from the feet to the eyes of the person they were looking at. If two people make eye contact, they scream. What is the probability qn, say, of at least one pair screaming? The purpose of this note is to put this problem in its natural probabilistic setting, namely that of a random mapping whose core is a derangement, for which many properties can be calculated simply. We focus primarily on the small components, but comment on other limiting regimes in the discussion. We begin by describing the usual model for a random mapping.

Defensive Manual
TEAMWORK SIMPLY STATED, TEAMWORK WINS CHAMPIONSHIPS! Team Philosophy There are only three things that I ask you to believe in unquestionably. If you believe in these three things then you will be a part of this team no matter what your abilities or talents may be or how many mistakes you may make. Likewise, if you do NOT believe in these three things with all your heart and soul, then you will not be a part of this team no matter what your abilities or talents may be or how perfect you may be. You must believe in: 1. YOURSELF. To be successful in anything you must believe (care, trust, confidence) in yourself. If you do not believe in yourself, no one else will. 2. TEAMATE. You must believe in your team mate. We cannot accomplish anything of great value in life without help. Even Jesus had help; he had 12 team mates; it only took one to betray him and the team. If you have a team mate that you do not believe in, then we must build him up 3. COACHES. Finally, you must believe in your leaders, the coaches for we are apart of the team. After Judas betrayed Jesus and the Jews crucified Him, the apostles denied knowing Him and went into hiding. But their faith in Him reunited them and revived their belief in each other which provided them the courage they needed to dedicate and give their lives to His teachings. Thanks to those faithful 11, the teachings of Jesus live today. Nothing of any great significance was ever accomplished alone. -
Rookie Tackle 7-Player Rule Book
ROOKIE TACKLE 7-PLAYER RULE BOOK American Development Model ROOKIE TACKLE 7-PLAYER TACKLE RULES Playing Field 1. The playing field is 40 x 35 1/3 yards, allowing for two fields to be created on a traditional 100-yard field at the same time. 2. The sidelines extend between the insides of the numbers on a traditional football field and should be marked with cones every five yards. Use traditional pylons, if available, to mark the goal line and the back line of the end zone. 3. Additional cones can be placed between the five-yard stripes and in line with the inside of the numbers to further outline the playing surface if desired. 4. All possessions start at the 40-yard line going toward the end zone. a. This leaves a 20-yard buffer zone between the two game fields for game administration and safety purposes. Game officials, league personnel, athletic trainers and designated coaches are allowed in this space. b. The offensive huddle may take place in the Administrative Zone. c. Players not in the game stand on the traditional sidelines with one or more coach(es) to supervise. d. The standard players’ box should be used for sideline players. With the field split in two, this keeps players between the 25- and 40-yard line on each respective field and side. 5. First downs, down markers and the chain gang are administered in accordance with National Federation (NFHS) or local rules – starting from the 40-yard line. Coaches and players not in the game stand here ADMINISTRATIVE END ZONE ZONE END ZONE Coaches and players not in the game stand here 2 7-Player Rules Rookie Tackle uses the NFHS rule book as a base and employs the following adjustments for 7-player football. -

The central algorithm is Fisher scoring and iterative reweighted least squares. At the heart of this package are the vector generalized linear and additive model (VGLM/VGAM) classes. VGLMs can be loosely thought of as multivariate GLMs. VGAMs are data-driven VGLMs that use smoothing. The book ``Vector Generalized Linear and Additive Models: With an Implementation in R'' (Yee, 2015) <DOI:10.1007/978-1-4939-2818-7> gives details of the statistical framework and the package. Currently only fixed-effects models are implemented. Many (150+) models and distributions are estimated by maximum likelihood estimation (MLE) or penalized MLE. The other classes are RR-VGLMs (reduced-rank VGLMs), quadratic RR-VGLMs, reduced-rank VGAMs, RCIMs (row-column interaction models)---these classes perform constrained and unconstrained quadratic ordination (CQO/UQO) models in ecology, as well as constrained additive ordination (CAO). Hauck-Donner effect detection is implemented. Note that these functions are subject to change; see the NEWS and ChangeLog files for latest changes.

Football Rules and Interpretations 2018 Edition
INTERNATIONAL FEDERATION OF AMERICAN FOOTBALL FOOTBALL RULES AND INTERPRETATIONS 2018 EDITION 2018.2.2 Foreword The rules are revised each year by IFAF to improve the sport’slev el of safety and quality of play,and to clarify the meaning and intent of rules where needed. The principles that govern all rule changes are that theymust: •besafe for the participants; •beapplicable at all levels of the sport; •becoachable; •beadministrable by the officials; •maintain a balance between offense and defence; •beinteresting to spectators; •not have a prohibitive economic impact; and •retain some affinity with the rules adopted by NCAA in the USA. IFAF statutes require all member federations to play by IFAF rules, except in the following regards: 1. national federations may adapt Rule 1 to meet local needs and circumstances, provided no adaption reduces the safety of the players or other participants; 2. competitions may adjust the rules according to (a) the age group of the participants and (b) the gender of the participants; 3. competition authorities have the right to amend certain specific rules (listed on page 13); 4. national federations may restrict the above sothat the same regulations apply to all competitions under their jurisdiction. These rules apply to all IFAF organised competitions and takeeffect from 1st March 2018. National federations may adopt them earlier for their domestic competitions. Forbrevity,male pronouns are used extensively in this book, but the rules are equally applicable to female and male participants. 2 Table of -
