A Revision Of The Genus Strategus (Coleoptera: Scarabaeidae), Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

The New World genus Strategus Kirby is here defined and revised for the first time. Eight species are described as new: S. atlanticus, S. caymani, S. craigi, S. hipposiderus, S. howdeni, S. longichomperus, S. symphenax, and S. tarquinius; 12 new junior synonyms are established (including the rejection of six previously valid species); one species is raised from synonymy; and two new replacement names are proposed. Strategus now contains one fossil species and 31 valid extant species. A key to the males and females of all the species is provided for the first time. All taxa are described or redescribed …

The Bryas Palace Of Theophilus, Carol Bier

Textile Research Works

According to the Continuation of the chronicles of Theophanes the Bryas palace of Theophilus (829-842) was built in imitation of an Arab palace. The present inquiry into its Islamic source offers a new interpretation of the Bryas palace within the context of Middle Byzantine secular architecture and the development of court ceremonial. ::?revious studies have concentrated upon locating Bryas in efforts to determine the extent of Islamic impact on the architecture of Byzantium. The most recent attempt, put forth by Dr. Semavi Eyice, tentatively links the unexcavated ruins at KUyUkyal!, a suburb of Istanbul, with the literary description of Bryas …

Spring Mortality Of Insectivorous Birds In Southern Manitoba, Jerome R. Serie, Robert E. Jones

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Migrating passerines frequently encounter adverse weather during their northward movements in early spring. Inclement weather often causes temporary halt of migrating passerines short of their destinations (Curtis 1969). In May 1974, such a grounding of spring migrants occurred in southwestern Manitoba due to unseasonable weather. Many insectivorous birds became weakened or died of starvation as a result of exposure to low temperatures, depletion of fat reserves, and lack of available food.

Arrival of Spring Migrants

The first large influx of insectivorous birds, mainly Myrtle (Dendroica coronado coronata) and Yellow (Dendroica petechia) Warblers, was noted on 19 …

The Behavior And Ecology Of Herotilapia Multispinosa (Teleostei, Cichlidae), Jeffrey R. Baylis

Investigations of the Ichthyofauna of Nicaraguan Lakes

Because of their complex social behavior and the ease with which they can be manipulated, cichlid fishes have long been of special interest to the ethologist. However, most of the research into cichlid behavior has been on Old World species. The social behavior of New World species is different and deserves more study. This paper will describe the ethology of one of the Central American cichlids, Herotilapia multispinosa.

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide contains hand signals useful for communicating around noisy equipment and from a distance.

Throughout history, man has devised methods of contacting others who were out of voice range or who could not be heard because of excess noise. The Indians were skilled at using smoke signals or by imitating some form of wildlife such as the owl or coyote.

The early explorers used other signs to guide them. The slashing of bark on trees or sticks pointed in a certain direction were keys for keeping the persons from getting lost or for others to follow.

The Midas Cichlid In Nicaragua, George W. Barlow

Investigations of the Ichthyofauna of Nicaraguan Lakes

Cichlasoma citrinellum (Gunther), the Midas cichlid, is the most important food fish in the Great Lakes Basin of Nicaragua. It occurs in the majority of the lakes, where it is the most ubiquitous cichlid fish, but it is uncommon in the rivers. The fry are carnivorous while the juveniles and adults are omnivorous, eating mostly Aufwuchs, snails, and fish. The Midas cichlids suffer from a number of diseases in nature and in the laboratory, including lymphocystis and nocardiosis. Potential predators vary from sharks and sawfish in Lake Nicaragua, to just one cichlid relative in one crater lake; in Lake …

Reproduction Of The Bull Shark, Carcharhinus Leu Cas , In The Lake Nicaragua-Rio San Juan System, Norman H. Jenson

Investigations of the Ichthyofauna of Nicaraguan Lakes

Carcharhinus leucas, the bull shark, or cub shark, is a member of a large family, the Carcharhinidae, sometimes called requiem sharks. It is of medium size, reaching a maximum of a little more than three meters in some parts of its range, but little more than two and one-half meters in my study area. It is euryhaline, able to live for extended periods of time in both freshwater and marine environments. It is a viviparous shark, retaining the young and nourishing them by means of a yolk-sac placenta.

Simplified Rbe-Dose Calculations For Mixed Radiation Fields, Robert Katz, B. G. Fullerton Jr., R. A. Roth, S. C. Sharma

Robert Katz Publications

A problem for radiobiology, radiation protection and treatment planning is the calculation of RBE as a function of the delivered dose when this dose is a result of a mixture of low and high LET radiations, as for neutron and pion beams. Track structure theory (Katz and Sharma, 1975) has recently been used to produce an algorithm for calculating survival, RBE, and OER as a function of dose in such environments. This simple formulation is based on the concept of irradiation equivalence (Katz et al., 1972) through which the effect of a mixed radiation environment is calculated as if it …

Consumer Behavior In The Health Marketplace: A Symposium Proceedings: Contents, Schedule, And Preface, Ian Newman

Consumer Behavior in the Health Marketplace: Symposium Proceedings

This symposium grew out of informal departmental discussions seeking new ideas concerning the effectiveness of health education, particularly as it is applied to the purchase of health related products and services. Two specific objectives were established to guide the program: 1) to bring together a cross section of experts to discuss, each from his/her own perspective, issues of consumers and their behavior in purchasing health related goods and services. By providing a platform of notable speakers we hoped to achieve the second objective, to attract interested people from the university community, Lincoln, and surrounding communities. We hoped that new contacts …

The Adult As A Consumer Of Learning, Malcolm Knowles

Consumer Behavior in the Health Marketplace: Symposium Proceedings

What I would like to do is explore with you what I think we know (and I will try to separate what we know from what we speculate about, as far as I can) about the behavior in the marketplace of adults as learners. Those of you who are in health education will find relevance in terms of patient teaching, of public health education, and even in pre-service and in-service education of health educators. Those of you who are not in health education can make applications to your respective fields of work.

Let me start by developing a little historical …

The Stanford Heart Disease Prevention Program, Nathan Maccoby

Consumer Behavior in the Health Marketplace: Symposium Proceedings

This afternoon I want to tell you about the results of a major study we have been doing as a part of the Stanford Heart Disease Prevention Program. The Stanford Heart Disease Prevention Program is an interdisciplinary project directed by Dr. John W. Farquhar, Professor of Medicine at Stanford University and I am co-director. This paper was really co-authored by fifteen people as part of an interdisciplinary team. With a group of different people like this, we had to spend a significant amount of time trying to teach each other our respective professional languages. Initially, communication within our group was …

Whose Behavior In What Health Marketplace?, Leon S. Robertson

Consumer Behavior in the Health Marketplace: Symposium Proceedings

A number of behavioral scientists and health educators have been engaged for some time in attempts to explain and/or influence human behavior regarding health and illness. Behavior directed toward preserving health is called health behavior.1 Behavior subsequent to the perception of symptoms and directed toward diagnosis and treatment is called illness behavior.

It has been suggested that techniques used to market products and services can be used to help individuals fulfill their needs in both prevention and amelioration of illness as well as in the alleviation of other social problems. In this paper I shall review some principles that have …

Some Lessons From The Feeling Good Television Series, James W. Swinehart

Consumer Behavior in the Health Marketplace: Symposium Proceedings

There has been a lot of discussion recently, in the press and elsewhere, about the need for more preventive health action on the part of the public. This concern was the basis for the Feeling Good project. The original proposal was for 26 one-hour programs to be broadcast weekly on Public Broadcasting Systems (PBS). When we were about 6 programs into the series, however, the decision was made to stop after the first 11 one-hour shows, take a two-month break to retool and return with 13 half-hour shows.

Leon Robertson talked about some of the problems with using education as …

Bottom Sediments Of Lake Nicaragua And Lake Managua, Western Nicaragua, Frederick M. Swain

Investigations of the Ichthyofauna of Nicaraguan Lakes

Lakes Nicaragua and Managua are large, rather shallow, fresh-water bodies that lie in a late Tertiary and Quaternary graben in western Nicaragua.
The bottom sediments comprise highly organic diatomaceous volcanic silts and clays in which quartz plagioclase feldspar, dioctahedral montmorillonite and volcanic glass are the principal constituents.
Organic nitrogen content of the lake sediments ranges from 0.3-1.2 percent, about the same range as in eutrophic lakes of higher latitudes. Bitumen content is rather low, much like that of oligotrophic lakes. Hydrocarbon fractions of bitumens are similar in amount to an alkaline lake of western U. S. Non-hydrocarbon bitumens are high …

Hemoglobin Stability In Bull Sharks, Jack D. Burke

Investigations of the Ichthyofauna of Nicaraguan Lakes

No significant differences in oxyhemoglobin affinity, or electrophoretic patterns of hemoglobin were found in 18 bull sharks collected in selected regions of Lake Nicaragua, the Rio San Juan, and the Caribbean Sea. The half-saturation of hemoglobin with oxygen (P50) was 11 and 17 mm Hg at pH 7.4 and 6.8, respectively (25° C, 3% hemoglobin solution, potassium phosphate buffer, 0.3 ionic strength). Electrophoresis resolved the hemoglobin into a minor and a major band. P1animetry of densitometric recordings showed that the major band constituted 54% of the total hemoglobin; the minor band, 46%. On the basis of these hemoglobin studies, no …

Body Fluid Solutes Of Juveniles And Adults Of The Euryhaline Bull Shark Carcharhinus Leucas From Freshwater And Saline Environments, Thomas B. Thorson, C. Michael Cowan, Donald E. Watson

Investigations of the Ichthyofauna of Nicaraguan Lakes

Since the discovery of the phenomenally high urea content of the body fluids of cartilaginous fishes by Staedeler and Frerichs (1858), the unique osmoregulatory system of this vertebrate class has been studied by many investigators. In broad outline, the mechanisms are essentially similar in all three of the major subtaxa: the selachians, the batoids, and the holocephalans. A single exception is the genus Potamotrygon (fresh-water stingrays of South America and Africa), which has apparently lost the ability to concentrate urea even when transferred to salt water.

A Revision Of The Genus Strategus (Coleoptera: Scarabaeidae), Brett C. Ratcliffe

Strategus now contains one fossil species and 31 valid extant species. A key to the males and females of all the species is provided for the first …

Selling Health To The Public, Godfrey M. Hochbaum

Consumer Behavior in the Health Marketplace: Symposium Proceedings

Let me confess at the outset that I feel uncomfortable with the title given to my presentation, "Selling Health to the Public," and that I feel equally uncomfortable with such terms as, "marketing health," "the health marketplace," or any others that equate the health area with the marketplace.

These terms have become quite popular in recent years because the presumed success of Madison Avenue and the methods and gimmicks of commercial sales promotion easily tempt health professionals to adopt these same methods and gimmicks in the cause of health education.

I feel uncomfortable with these terms and with what they …

Some Determinants Of Post-Purchase Satisfaction Among Medical Care Consumers, Lawrence Wortzel

Consumer Behavior in the Health Marketplace: Symposium Proceedings

Consumer behavior in the health marketplace is an interesting subject. One of the interesting things about studying medical care is that different people experience different results after having the same health care. For example, in the Massachusetts presidential primary that took place some time ago, one of the voting machines somehow got hooked up to an X-ray device, and, as a result, three voters were exposed to doses of radiation. One of the exposed was a conservative, one was a liberal, and one was an independent. They were immediately rushed to one of the major Boston medical centers where a …

New Themes In Innovation Research: Implications For Consumer Health Behavior, Gerald Zaltman

Consumer Behavior in the Health Marketplace: Symposium Proceedings

Whenever I am called upon to make prescriptive statements to a group which can't easily hold me accountable for the consequences, I am always reminded of the story of the chicken and the pig. For those of you who aren't familiar with the story, a chicken and a pig were walking down the street one day and came upon a restaurant that had a big sign in the window, "Special Today: Bacon and Eggs." The chicken got all excited and said, "Isn't that great, they are featuring us together." The pig looked kind of dour and said, "That's okay for …

Availability Of Trypotophan In Some Feedstuffs For Swine, Pedro H. Rivera L., E. R. Peo, Jr., T. Stahly, B. D. Moser, P. J. Cunningham

Department of Animal Science: Faculty Publications

Two experiments were conducted to determine the availability of tryptophan (Try) from corn (NC), opaque-2 corn (OC), milo (M) and freeze dried alfalfa (FDA) when fed to swine. The first experiment consisted of a growth trial involving 96 baby pigs and eight treatments. The basal diet containing .06% Try and 24.5% protein was supplemented with .015%, .030% and .045% L-Try. These four diets were used to establish a standard curve for growth. The other treatments were formed by adding the feedstuffs as the source of Try to the basal diet. Availabilities were determined by comparing growth responses. Try availabilities from …

Some Remarks On The Fecundity Of Tilapia (T. Mossambica Peters) And Its Introduction Into Middle Central America (Nicaragua) Together With A First Contribution Towards The Limnology Of Nicaragua, Dietmar Riedel

Investigations of the Ichthyofauna of Nicaraguan Lakes

a. This paper presents an account of fecundity studies into T. mossambica under Middle Central American conditions and limnological investigations into Lake Moyua/Nicaragua which have been performed during 1961/62.

b. Data obtained as to fecundity of T. mossambica are discussed in the light of the term prolificy and with regard to ecological and biological characteristics of Nicaraguan waters and native fish fauna.

c. A more detailed contemplation about the possible effects of a spread out or transplantation of T. mossambica into other Nicaraguan waters concludes the paper.

Ichthyology Of The Lakes Of Nicaragua: Historical Perspective, Jaime Villa

Investigations of the Ichthyofauna of Nicaraguan Lakes

Scientific study of Nicaraguan freshwater fishes did not begin until Gunther described the first species from Lake Nicaragua in 1864, but actual accounts of several interesting fishes were written as early as the sixteenth century by the first historians of the New World. These accounts ranged from hearsay to rather detailed (for their time) descriptions and first-hand observations on the form and life of some species. In some cases these observations or conclusions have been doubted for many decades but confirmed and elaborated in recent years. Therefore I believe it may be of interest to examine the early chronicles.

Some Speculations About "The Great Nicaraguan Lake", Jaime Villa

Investigations of the Ichthyofauna of Nicaraguan Lakes

The available evidence indicates that Lakes Managua and Nicaragua were broadly connected in the past, when most of the fish species invaded the "Great Nicaraguan Lake". Due to the lowering of the water level (caused perhaps by tectonic movements and/or erosion produced by the Rio San Juan), Lake Managua became separated from Lake Nicaragua in the Tipitapa area. Water movement from Lake Managua is achieved mostly by seepage through a porous dropoff which prevents the exchange of fishes between the lakes. At about the same time, if not earler, Lake Xilml also became separated. After the more or less permanent …

The Status Of The Freshwater Shark Of Lake Nicaragua, Thomas B. Thorson, Donald E. Watson, C. Michael Cowan

Investigations of the Ichthyofauna of Nicaraguan Lakes

Nineteen sharks collected from freshwater at several points on Lake Nicaragua and the Rio San Juan were all of the same species and indistinguishable from marine Carcharhinus leucas of the Atlantic. Minor differences previously thought to separate C. leucas from the lake shark proved to be invalid. Females had slightly longer gill slits, somewhat greater breadth of pelvic fin, and a longer abdominal region than males. Clasper length indicated that the onset of sexual maturity in males occurs when they are between 1,600 and 1,700 mm in total length.
The classical theory or origin of the sharks from Pacific ancestry …
