Field Biology at Algona High School, Summer, 1960

The class was made up of seven junior and senior boys who had already successfully completed a regular one-year course in biology. The overall classroom time was 120 hours. Five hours were spent in the school and the remaining time was spent in the field. During the 5-week course, dove banding, wildlife survey of a section of land, gill-netting of fish, vegetation transect, and identification of birds, plants, fish, reptiles, amphibians, and mammals was carried on

The Invertebrate Prey of the Northern Leopard Frog, Rana pipiens, in a Northeastern Ohio Population

Author Institution: Department of Biological Sciences, Kent State UniversityThe purpose of this investigation was to determine the feeding habits of the northern leopard frog, Rana pipiens, in northeastern Ohio. To accomplish this we examined the stomach contents of 13 adults and 19 juveniles collected from a restored wetland in Summit County, Ohio during the summers of 1996 and 1997. The adult and juvenile frogs ingested 142 invertebrates representing 2 phyla, 3 classes, 12 orders, and 34 families. Adult and juvenile frogs consumed both diurnal and nocturnal prey belonging primarily to the insect orders Coleoptera, Hemiptera, and Hymenoptera. Although juvenile frogs consumed more individual prey items than adults (t = 2.196, p <0.05), neither age cohort specialized on active or inactive prey (X2 = 3.84, p <0.05)- Approximately 67% of all prey consumed consisted of fossorial or crawling organisms. Our data suggest that R. pipiens is an efficient predator that maximizes prey diversity by employing more than one feeding strategy

Changes in Fish Populations and Food Habits of Yellow Bass in North Twin Lake, 1956-1958

Fish population studies initiated in 1953 indicated that most species were on the increase until the winter kill of 1955. In 1956, populations were below normal; in 1957 there was an increase in most species, followed by a decrease in 1958. Studies during 1953 and 1954 showed that the food of adult yellow bass consisted to a great extent of young-of-the-year yellow bass and gizzard shad, along- with insects. During the summers of 1956, 1957, and 1958, forage fish were of very minor importance in the diet of yellow bass; they fed mainly on immature insects and minute crustacea

Using physical barriers to prevent carrot fly (Psila rosae (Fabricius)) damage in domestic production

A field experiment was used to assess the effectiveness of different barriers in protecting garden‐scale carrot production from carrot fly (Psila rosae (Fabricius)) damage. Some of the vertical barriers tested were found to provide a useful method of protecting early season carrots from carrot fly in terms of the percentage of carrots free from damage but, under cumulative pest pressure of several generations of carrot fly, such barriers were found to provide insufficient protection. Gardeners should therefore completely cover their carrot crop to attain an acceptable level of control, and this was found to be especially important for carrots harvested later in the season. There were positive effects of some barrier types on yield which may be due, at least in part, to the protection given by the barriers to carrot seedlings

A Linguistic Analysis of Three People with No Prior AAC Experience Using an AAC Device

Since approximately 50% of people with aphasia experience incomplete restoration of language, augmentative and alternative communication (AAC) for people with aphasia has been used primarily as a compensatory therapeutic intervention. AAC is less frequently considered to restore linguistic functions (Weissling & Prentice 2010). Recently, researchers described the communication patterns used by people with aphasia when they retold personal narratives using four different AAC screen layouts (Dietz, Griffith, & Macke, 2014; Dietz, Weissling, Griffith, & McKelvey, 2014; Griffith, Dietz, & Weissling, 2014). Across these reports, the people with aphasia employed a variety of expressive modality units (i.e., spoken, written, drawn, picture, text box, and speak button) to retell their stories; however, they predominately used the spoken modality to retell each story. Despite the presence of an AAC device, they spoke, on average 70% of the time across all retells, (Dietz et al, 2014a; 2014b; Griffith et al., 2014). The question remains, though, whether these high levels of spoken output translates in to more effective and efficient verbal expression. Therefore, as such, the purpose of this retrospective case series study was to describe and analyze the spoken linguistic output of the people with aphasia and no prior AAC experience from the Dietz et al., (2014a; 2014b) studies

Life\u27s Simple 7 and Health Care Utilization among the Framingham Generation III Cohort

Abstract Objective: To evaluate associations of cardiovascular health status with utilization of healthcare services. Methods: Our study included 3,786 participants from the Framingham Third Generation Cohort (enrollment: May 2008 – February 2011). LS7 0-14 point summary scores were categorized as “suboptimal” (score of 0-7) and “optimal” (score of 8-14). Participants were stratified into two utilization groups. Those with 0-1 utilizations were compared to those with 2 or more visits ( Super Users”). Logistic regression was used to estimate associations of the two LS7 categories with the odds of Super User utilization (models adjusted for age, sex, race, and education). Results: Compared to those with “suboptimal” LS7 scores, participants with “optimal” LS7 scores had a 40.5% lower odds (95% confidence interval: 28-51%) of being a “Super User” of health care services (p\u3c0.005). Conclusions: In a younger population, higher LS7 cardiovascular health metric scores were associated with lower utilization of costly health care services. Public Health Implications: These results may have implications for primary care physicians and other health professionals to help identify patients at risk for over-utilization of higher-cost health care services

The Pine Needle, February 1947

Libraries and archives collect materials from different cultures and time periods to preserve and make available the historical record. As a result, materials such as those presented here may reflect sexist, misogynistic, abusive, racist, or discriminatory attitudes or actions that some may find disturbing, harmful, or difficult to view. Both a humor and literary magazine, The Pine Needle was a University of Maine student-produced periodical that began publication in the fall of 1946, the first post-World War II semester that saw GIs returning to campus. The Needle reflected an edginess and rebellion not found in previous UMaine student publications. While past student publications relied on euphemisms for alcohol and dating on campus, The Needle overtly sexualized co-eds and discussed the use of drugs, tobacco, and alcohol by students. Cover art for this issue is an unsigned pen-and-ink illustration produced by a member of The Needle\u27s art staff. It depicts the five members of the editorial staff gathered around a wood coffin labeled, The Needle. Included in this issue is a piece about former History Professor C. Dewitt Hardy II\u27s (1911-1992), term paper assignment entitled, Social Problems in My Home Town. The work mentions the birth of Hardy\u27s son and future artist, Clarion Dewitt Hardy III (1940-2017)

AAC revolutionizes aphasia therapy: Changes in cortical plasticity and spoken language production

Restorative interventions are frequently preferred as augmentative and alternative communication (AAC) interventions are thought to impede neural recovery (Pulvermuller & Berthier, 2008; Weissling & Prentice, 2010). But, clinical observations suggest AAC interventions may improve aphasia (Dietz, Weissling, Griffith, & McKelvey, 2012). The purpose of this study was to compare the influence of a novel AAC and traditional restorative (TR) intervention on linguistic recovery and neural reorganization
