Aquatic insect populations in transplanted and natural populations of the purple pitcher plant, Sarracenia purpurea, on Prince Edward Island, Canada
No full textIn early July 1991, 234 pitcher plants (Sarracenia pulpurea) were transplanted from a Prince Edward Island bog being mined for peat into three bogs that varied with respect to previous pitcher plant abundance. One bog had a thriving natural pitcher plant population prior to transplant, while the other two had fewer than three pitcher plants. Between mid-June and late August 1993, abundances of the pitcher plant inquilines Wyeomyia smithii (Diptera: Culicidae), Metriocnemus knabi (Diptera: Chironomidae) and an unidentified sarcophagid fly (Diptera: Sarcophagidae) from transplant bogs were compared with remaining populations in die source bog and with other natural populations. Of the three inquilines, W. smithii was the most severely affected by transplant; it was extremely rare or absent in transplanted pitchers, although it was found in all other bogs investigated on Prince Edward Island. Metriocnemus knabi larvae were common in ail bogs investigated, except for those transplant bogs where pitcher plants were rare prior to transplant. Sarcophagid larvae were found in all of the bogs sampled, and were apparently unaffected by transplant. Desiccation during the transplant process, as well as the time of the transplant, may play a role in the success of recolonization of the pitcher plants after transplanting.PT: J; CR: ADDICOTT JF, 1974, ECOLOGY, V55, P475 BRADSHAW WE, 1984, AM MIDL NAT, V112, P294 CAMERON CJ, 1977, CAN J ZOOL, V55, P2018 ELLIOTT JM, 1977, FRESHWATER BIOL ASS, V25 FAIRCHILD WL, 1987, CAN ENTOMOL, V119, P647 FARKAS MJ, 1986, CAN ENTOMOL, V118, P1307 FARKAS MJ, 1986, CAN J ZOOL, V64, P285 FISH D, 1978, AM MIDL NAT, V99, P172 FORSYTH AB, 1975, CAN J ZOOL, V53, P174 GIVNISH TJ, 1989, PLANT ANIMAL INTERAC, P243 HEARD SB, 1994, ECOLOGY, V75, P1647 HEARD SB, 1994, ENVIRON ENTOMOL, V23, P1250 ISTOCK CA, 1975, EVOLUTION, V29, P296 ISTOCK CA, 1983, PHYTOTELMATA TERREST, P191 JUNIPER BE, 1989, CARNIVOROUS PLANTS MOGI M, 1980, TROPICAL MED, V22, P1 MOORE PD, 1974, PEATLANDS NASTASE AJ, 1991, AM MIDL NAT, V125, P356 NASTASE AJ, 1995, AM MIDL NAT, V133, P44 PATERSON CG, 1982, CAN J ZOOL, V60, P3075 SCHNELL DE, 1976, CARNIVOROUS PLANTS U WALLIS RC, 1967, MOSQ NEWS, V27, P9; NR: 22; TC: 5; J9: CAN J ZOOL; PG: 8; GA: VQ081Source type: Electronic(1

Comparison of prediction methods for batter-pitcher matchups
No full textBaseball is full of confrontations and these confrontations between a batter and the pitcher is what makes the game. If a formula would be able to predict the probability of the outcome correctly, when they meet, wouldn’t it instill confidence in the minds of the head coach (or you if you are playing the fantasy) to select someone who would be on the winning end? We would like to know for sure, which of our batters are good, and what out of the small amount of possible outcomes, will be the result when he faces this other good pitcher from the team you face next. It seems the past performance of the batter against this pitcher can be a good indicator, and that is what presumably the methods currently used utilize. But the utility of the Batter vs. Pitcher data in predicting the future outcome is a debate going on for quite a time now. The reason for this debate stems from the fact that the sample size of this data is so small that it becomes hard to comprehend when to prefer information you get from a sample size of thousands of atbats against all pitchers vs. maybe a few dozen against specific individuals. The report will discuss one of the famous methods, called Log5 [1] that has been utilized so far when it comes to measuring the outcomes of these confrontations. It also discusses the other methods like logistic regression based on the past data and the new and upcoming Morey-Z. [3]Mechanical Engineerin
Beer, Brats, Cheese, and-- Baseball: The History and Impact of Baseball in Wisconsin
No full textFrom the 1800s baseball became a passion for the citizens of the United States. Wars, recessions and scandals could not bring down what is known as "America's Pastime." However baseball and other professional sports have been getting a bad name since historians and economist have started to look at the correlation between the team and the community. The notion of, "build us a new stadium at the cost of the tax payers or we are taking our team elsewhere" has been a common trend since 1950's. By looking at Appleton and Milwaukee this paper will look at the impacts baseball has on these communities both culturally and economically from 1966 to 2012

No full textThe article discusses the carnivorous plant the Purple Pitcher Plant, or Sarracenia purpurea L., on Prince Edward Island. It focuses on research at the University of Prince Edward Island (UPEI) on the Purple Pitcher Plant, noting its presence in bogs such as the Glenfinnan Bog. The author comments on research conducted by UPEI undergraduate students Ricki Sulis and Vaneeta Verma from the laboratory of biologist Christian Lacroix on pitcher plant developmental morphology and anatomy and on research conducted by undergraduate students Loretta Hardwick, Dylan Blacquiere, and Jackie Wood from the laboratory of entomologist D.J. Giberson on aquatic insects that live inside pitcher plants.Source type: Print(0
Defining the word “seamount”

Schmincke, 2000; Pitcher et al., 2007; International Hydrographic
Organization, 2008; Wessel et al., 2010) but there is no “generally

Relationship between pitcher fatigue and medial elbow torque in baseball pitchers: A simulated game analysis
No full textObjectives: The incidence of overuse injury to the elbow in baseball pitchers continues to rise, despite exhaustive efforts at pitch count regulations and emphasis on proper throwing mechanics. The goal of this study was to determine if the medial elbow experiences increased torque levels as the pitcher fatigues through the course of a simulated game. Methods: Competitive baseball pitchers were recruited for this simulated game study. Medial elbow torque was assessed using a validated mobile sensor that recorded medial elbow torque during the throwing motion. A radar gun was used to capture pitch velocity for each recorded pitch. Each pitcher completed a simulated game consisting of 6 innings and a standardized pitching scheme of fastballs, curveballs, and change-ups. Visual analog scores (VAS) measuring fatigue were recorded in between each inning. In total, each pitcher threw 90 pitches. Data was recorded every pitch to include ball velocity, medial elbow torque, arm speed, arm rotation, and arm slot. Results: A total of 11 pitchers (average age 17.6 years; range 15-20 years) completed the study. No adverse outcomes were noted with use of the mobile sensor. VAS scores increased 0.716 points per inning pitched (p\u3c0.001). Medial elbow torque also was found to increase with successive innings, with an increase of 0.836 Nm each inning (p\u3c0.001), while average pitch velocity was found to decrease as the game progressed (0.28 mile per hour decrease per inning; p\u3c0.001). Fastballs generated the highest amount of medial elbow torque. There were no differences found in arm rotation or arm speed as the game progressed. However, the arm slot was found to decrease with each successive inning (0.731 degree decrease per inning; p\u3c0.001). Conclusion: In this simulated game analysis, pitchers were noted to experience increase fatigue after each successive inning. While the average fastball velocity decreased from inning-to-inning, the medial elbow torque was found to increase, signifying a possible risk factor for overuse injury to the medial elbow

Using Stepwise Logistic Regression to Determine Substitutions in Baseball
No full textabstract: In baseball, a starting pitcher has historically been a more durable pitcher capable of lasting long into games without tiring. For the entire history of Major League Baseball, these pitchers have been expected to last 6 innings or more into a game before being replaced. However, with the advances in statistics and sabermetrics and their gradual acceptance by professional coaches, the role of the starting pitcher is beginning to change. Teams are experimenting with having starters being replaced quicker, challenging the traditional role of the starting pitcher. The goal of this study is to determine if there is an exact point at which a team would benefit from replacing a starting or relief pitcher with another pitcher using statistical analyses. We will use logistic stepwise regression to predict the likelihood of a team scoring a run if a substitution is made or not made given the current game situation
