Simpson, E. LeRoy, Playbook, 1954-1956

A Pittsburg State University football players’ playbook from the mid-1950s, a football program from 1951, and a newspaper clipping. Edward LeRoy Simpson was born in Miami, Oklahoma in 1934, to Eddie and Ada Simpson. From 1952-1956 LeRoy attended the Kansas State Teachers College (now Pittsburg State University). He played several positions on the football team, including quarterback, and lettered all four years. He went on to receive a master’s degree from the Kansas State Teachers College in 1961. After earning a doctorate, Dr. Simpson joined Wayne State College in Wayne, Nebraska in 1968 as an associate professor of human performance/leisure studies and athletic director. During his tenure of over 30 years teaching and coaching, he was the track and field and cross country coach from 1968 to his retirement in 1997. He started the women’s track program at Wayne State College and was inducted into the WSC Athletic Hall of Fame in 2001 and the Sioux City Relays Hall of Fame in 2009. He was married to Marian Simpson and they had one son. E. LeRoy Simpson passed away in 2011 in Woodland Park, Colorado.https://digitalcommons.pittstate.edu/fa/1422/thumbnail.jp

Cap a una cronologia dels models teatrals de Pedrolo

This article scans Pedrolo's dramatic oeuvre starting from the comparative analysis of story-line and thematic aspects, characters, space and time. The final ambition is to emphasize the fact that three periods may be defined: early theatrical experiments (1954-1956), central production (1957-1963) and the last plays (1966-1977), that respond to different theatrical models

Changes in lucerne pollinating wild bee assemblages in Hungary from the pre-pesticide era to 2007.

Als Ergebnis von fünf landesweiten Erhebungen seit der Zeit vor der Pestizid-Ära bis in die Gegenwart (1954-1956, 1967-1968, 1971-1972, 1998-2002, 2003-2007) wurden artenreiche Wildbienenzönosen an blühenden Luzernefeldern ermittelt. 196 Bienenarten, einschließlich der Honigbiene, wurden nachgewiesen. Aus dem Vergleich der Artenspektren der Blütenbesucher kann geschlossen werden, dass sich die Wildbienenzönosen in diesem Zeitabschnitt von etwas mehr als fünfzig Jahren deutlich verändert haben. Zunächst wurde ein dramatischer Rückgang von Eucera- und Tetralonia-Arten mit mittellanger Flugperiode zwischen der Zeit vor der Pestizid-Ära (1954-1956) bis in die Pestizid-Ära in Ungarn (1967-1968) festgestellt. Dieser Zustand blieb bis zur heutigen Zeit unverändert. Die Hauptursachen für diese Entwicklung sind der verstärkte Einsatz von Pestiziden auf Kulturböden sowie das Aufkommen einer regelmäßigen mechanischen Unkrautbekämpfung entlang von Straßen, Gräben und auf Kulturflächen. Ferner ist der Rückgang unkultivierter Flächen in Feldern und naturnahen Gebieten zugunsten einer intensiveren Agrarlandnutzung eine weitere Ursache für die bedeutende Veränderung in den Wildbienenzönosen. Gleichzeitig ist der Anteil von Hochsommer-Wildbienenarten mit kurzer Flugperiode (Melitta leporina (Pz.), Rhophitoides canus Ev.) während der 50er bis späten 60er Jahren beträchtlich größer geworden, weil sowohl die Anbaufläche für Luzerne als auch die Schlaggröße der Luzerne-Felder erheblich vergrößert worden waren. Dadurch wurden die Pollen-Ressourcen und Nistmöglichkeiten für diese spezialisierten Bienen vermehrt. Jedoch kehrt sich diese Tendenz im letzten Jahrzehnt um, weil die Nachfrage nach Futter-Leguminosen stark nachließ. In den letzten Jahren scheint sich ein neuer Trend entwickelt zu haben: die Dominanz von Hummeln (Bombus-Arten) hat stark zugenommen, die Abundanz von anderen Wildbienengruppen hat dagegen abgenommen.Stichwörterwild bees, changing dominance, effect of changing agriculture.As a result of five national surveys in Hungary from the pre-pesticide era up to recent years (1954-1956, 1967-1968, 1971-1972, 1998-2002, 2003-2007), rich wild bee assemblages were recorded at flowering lucerne fields. 196 bee species were detected, including the honey bee. Comparing the structure of wild bee assemblages visiting flowering lucerne fields in Hungary, it can be concluded that their species composition changed considerably in this period of rather more than fifty years. First, a dramatic decline of Eucera and Tetralonia species of medium flight periods was detected from the pre-pesticide era (1954-1956) up to the pesticide era in Hungary (1967-1968). This situation remained unchanged up to the present time. The main reason for this is the more widespread use of herbicides on arable land, as well as mechanical weed control becoming a regular practice along roadsides, ditches and in fields of cultivated crops. The decline of non-cultivated ruderal plots in cultivated crop fields and nearly-natural areas at the expense of more intense agricultural land use are also responsible for the considerable changes in the composition of wild bee assemblages. At the same time, the ratio of some mid summer wild bee species of short flight period increased considerably (Melitta leporina (Pz.), Rhophitoides canus Ev.) from the fifties up to the late sixties, because the acreage of lucerne production increased in this period and the size of individual lucerne fields was greatly enlarged, providing greater pollen resources and nesting possibilities for these specialist bees. This tendency, however, reversed in the past decade because lucerne production greatly decreased as a result of a greatly reduced demand for fodder legumes in Hungary. In recent years a new trend seems to have arisen, with a rapid increase in the dominance of bumble bees (Bombus species) and accompanying reduction in abundance of other groups of wild bee.Keywordswild bees, changing dominance, effect of changing agriculture
