The educational process, formal or informal consciously created, represents an essential investment necessary for industrialization; such education must be planned to fit the needs of a changing society so that as the Urban complex grows and demands expand. Education is the key with which to unlock the economic potential of the people. In contemporary developing countries, there is an incongruous relationship between education and their economies. This is reflected in the rising pool of the phenomenon of educated unemployed more than ever before. This paper examines the increasing problem associated with unemployment in Nigeria.

Picture Book Soldiers: Men And Messages, Christina M. Desai
Reading Horizons: A Journal of Literacy and Language Arts
This study examines children's picture books about soldiers and war, including fiction, folktales, and historical fiction, analyzing their implicit and explicit messages about war and the military, and evaluating them for gender stereotyping. The soldiers are found to conform almost uniformly to an exaggerated male stereotype. Different value judgments about war and conflict resolution are found in the fiction vs. the historical fiction and in the historical fiction about earlier vs. later historical periods.
Spanish-English Code Switching In A Bilingual Academic Context, Ruth R. Becker
Spanish-English Code Switching In A Bilingual Academic Context, Ruth R. Becker
Reading Horizons: A Journal of Literacy and Language Arts
This study investigates the Spanish-English code switching of 60 elementary Mexican American students in a story retelling activity. The students' story retellings were examined according to Becker's (1997) model of code switching: structural linguistic, internal psycholinguistic, and external social factors. Results suggest there is a positive relationship between code-switched story retelling, oral language usage, and enhanced narrative skills. Implications suggest that teachers explore the use of code switching in a story retelling activity as a practical way to enhance bilingual elementary students' verbal skills and reading development.
The Role Of Environmental Analogs In Identifying Potentially Invasive Woody Plants In Iowa, Mark P. Widrlechner
The Role Of Environmental Analogs In Identifying Potentially Invasive Woody Plants In Iowa, Mark P. Widrlechner
Journal of the Iowa Academy of Science: JIAS
Americans cultivate a large and diverse range of introduced woody plants as important sources of food and forest products, as well as for urban horticulture, amenity and wildlife plantings, and windbreaks. A small number of these species have become serious pests, disrupting well-established native plant communities or functioning as range and agricultural weeds. More of these species are not serious pests today, but have escaped cultivation and serve as potential sources of future outbreaks. Two other sources of potentially invasive woody plants are found among species that are not or are only rarely cultivated, about which we often know little …

The Journal of the Assembly for Expanded Perspectives on Learning
Morris Berman tells the story of his maternal grandfather, who, when he was five years old in 1883 or 1884, was sent to a Jewish elementary school in Belorussia. On the first day of class, the teacher startled the young boy by taking each child's slate and smearing the first two letters of the Hebrew alphabet—aleph and beys—on it in honey. His grandfather's first lesson consisted of eating the letters off the slate. The symbolism of this act is complex, Berman muses, but central to the ritual is the belief that what is real must be taken into oneself, ingested: …

Invasive Species In Iowa: An Introduction, James J. Dinsmore, Neil P. Bernstein
Invasive Species In Iowa: An Introduction, James J. Dinsmore, Neil P. Bernstein
Journal of the Iowa Academy of Science: JIAS
Concern over the increasing spread of invasive species and the potential impacts of those species on native communities has been the subject of several books and hundreds of research papers in recent years. President Clinton's Executive Order on invasive species in February1999 raised national attention to this issue. Natural resource agencies have been plagued by an ever-increasing number of invasive species and now consider this issue the second most important problem (after habitat loss) in their fight to maintain some semblance of natural communities on this planet. One group of experts estimated that in the United States alone, invasives cost …

War On Weeds: Winning It For Natural Areas, Jerry E. Asher
Journal of the Iowa Academy of Science: JIAS
I am delighted to be here with you today to discuss the rapidly accelerating damage that invasive exotic plants are inflicting on natural areas in this country. This problem may seem overwhelming, but you need not despair because there are economical, realistic, and effective strategies available to meet this challenge.
There are two purposes to this presentation: to give you information you can use to convince others that invasive exotic plants are seriously harmful, and to suggest that we can win this war on invasive exotic plants if we engage enough of the right people.

An Overview And Management Plan Of Iowa's Non-Native, Invasive, Terrestrial Forbs, Deborah Q. Lewis, Richard O. Pope
Journal of the Iowa Academy of Science: JIAS
Non-native, invasive forb species have been a problem in Iowa since the earliest decades of Iowa's European settlement. The history of studies of Iowa's invasive plants began with L. H. Pammel, and these studies continue to present. Three tables cite the occurrence of many of these species in the state, with Table 1 listing 93 non-native forbs reported by Pammel, Table 2 citing ten invasive forbs of natural areas, and Table 3 adding 38 observed or potential aggressive species of Iowa's anthropogenic and natural areas.
There has been a divergence of interest and research in the management of invasive species …
Iowa's Non-Native Graminoids, Thomas R. Rosburg
Iowa's Non-Native Graminoids, Thomas R. Rosburg
Journal of the Iowa Academy of Science: JIAS
Iowa's non-native graminoids include 60 species of grasses and one species of bulrush. The exotic grass species comprise a large proportion (about 31%) of the total species richness of grasses in Iowa, which are second only to the Asteraceae in terms of total species. About half of the non-native graminoids (52%) occur sporadically and form sparse, non-invasive populations, while eighteen species (about 30%) are commonly encountered in large populations throughout the state. About 60% are annuals and a large majority (89%) has been introduced from either Europe or Asia. The C3 photosynthetic pathway is prevalent, occurring in approximately two-thirds of …
Eurasian Watermilfoil: Status And Management In Iowa, Gary S. Phillips
Eurasian Watermilfoil: Status And Management In Iowa, Gary S. Phillips
Journal of the Iowa Academy of Science: JIAS
In 1993, Eurasian watermilfoil (Myriophyllum spicatum L.) was discovered in Crystal Lake, Hancock County, Iowa. During the next three years, new infestations were discovered by the Iowa Department of Natural Resources (IDNR) fisheries personnel in four Iowa lakes. In July 1996, a program was established by the IDNR to address the threat posed by Eurasian watermilfoil to Iowa's aquatic ecosystems. As part of the Eurasian Watermilfoil Program, statewide aquatic vegetation monitoring was begun to identify those lakes currently infested with Eurasian watermilfoil. Monitoring activities were conducted by IDNR field technicians during the summers of 1996 through 2000. During this time …
Non-Native Amphibians And Reptiles In Iowa, James L. Christiansen
Non-Native Amphibians And Reptiles In Iowa, James L. Christiansen
Journal of the Iowa Academy of Science: JIAS
Only a few species appear as introductions into Iowa in the last 30 years. The bullfrog, Rana catesbeiana, was systematically introduced along with fish stocked from hatcheries in the 1930s and this species continues to spread in northern Iowa where it poses a hazard to smaller frogs. Turtles sold as pets, primarily map turtles (Graptemys pseudogeographica and G. geographica) and red-eared turtles (Trachemys scripta) continue to be found in scattered ponds, usually rural, throughout the state. The eastern box turtle (Terrapene carolma) has been reported in or on the edge of most major Iowa cities even though no breeding population …

Introduced Fungi: Some Cause Significant Plant Disease Problems, Lois H. Tiffany
Introduced Fungi: Some Cause Significant Plant Disease Problems, Lois H. Tiffany
Journal of the Iowa Academy of Science: JIAS
Species of the three groups of fungi characterized here on the basis of their energy source acquisition have differing potentials for becoming problem organisms following introduction as alien fungi new to Iowa. The decomposer group of fungi that obtain an energy supply by action of extracellular enzyme activity on dead plant tissues typically have perennial mycelium, are cosmopolitan in distribution, and are unlikely to become problems even if established. The second group, the mycorrhizal/lichen group are highly specific in their relationships. The mycorrhizal fungus group have a potential for being introduced as mycorrhiza already established with the roots of particular …
