Studies on the mutagenic consequences of the major DNA adduct of the potent carcinogen benzo[a]pyrene
(Boston University, 1988) Ezzedine, Zahra D
Most known carcinogenic substances are also mutagenic. This relationship is sensible because oncogenes, which are postulated to be a fundamental element of the carcinogenic process, are in some instances derived from their normal cellular counterparts via specific mutations.
The West African Monetary Union: the economics of a dependent monetary system
(Boston University, 1988) Evlo, Kodjo
The West African Monetary Union is one of the rare examples of complete monetary integration in the world today. It is a unique kind of monetary union because the reason for its creation is not to facilitate existing trading and financial relations between its members;
Education and national values in Nigeria: an empirical study
(Boston University, 1988) Esedo, Kingsley E
The drive for modernity is the preoccupation of developing countries. Toward this end, the formal education system is viewed as an indispensable tool for political socialization.
The development of counseling psychologists' empathic experience and its relationship to self understanding
(Boston University, 1988) Erwin, Hope E
This study sought to understand counseling psychologists' empathic experience of clients. It explored how empathy and self understanding developed and informed counseling skills.

Endothelial cell regulation of polymorphonuclear leukocyte motility and diapedesis in vitro
(Boston University, 1988) Doukas, John T
Polymorphonuclear leukocyte (PMN) migration across endothelial cell (EC) monolayers cultured on acellular amnionic membrane was used as an 1n vitro approximation of diapedesis, to examine the direct influence of confluent endothelial monolayers on PMN motility. PMN random motility and chemotaxis across polycarbonate filters were also studied to determine the influence of EC-derived metabolites and other exogenously applied agents. ECs were aeen to regulate PMN diapedesis and motility by two means. One, by altering intracellular microfilament arrays, ECs increase or decrease monolayer junctional integrity, and thereby present a variable barrier to PMN diapedesis as well as macromolecular permeability. Microfilament arrangements are altered by the vasoactive amines histamine, norepinephrine, and serotonin, by the eicosanoids thromboxane (Tx) ~ and the stable metabolite of prostacyclin, 6-keto-PGFJa • and by the fungal metabolites cytochalasin B and phalloidin. Two, ECs release metabolites that directly influence PKN motility. TxB 2 and an unidentified lipoxygenase product increase PMN diapedesis, random motility, and chemotaxis, and act as chemoattractants. 6-Keto-PGF la increases or decreases diapedesis and chemotaxis depending on its concentration. Release of EC eicosanoids is substrate modulated, with a greater release induced by extracellular matrices as compared to gelatin or plastic aubstrates. These two EC-baaed regulations of PHN motility are interrelated, as vasoactive amines also modulate EC eicosanoid production, and eicosanoids alter EC cytoskeletal patterns and therefore permeability. Both of the EC-based regulations of PMN motility are similarly manipulated by exogenous agents such as amines, arachidonic acid, or arachidonic acid metabolism inhibitors. It is concluded that ECs influence PKN motility and diapedesis by at least two mechanisms, and that these mechaniams can be modulated by various exogenous agents.
Metalinguistic awareness: judgment and segmentation skills in preschool children
(Boston University, 1988) Donnelly, Carol B
This study investigated the development of metalinguistic awareness in preschool children. The purpose was to observe three and four-year-old's ability to judge whether two linguistic items were identical or not and their ability to identify a segment (word phoneme or morpheme) which was present in one item but omitted in a second. The study examined the effect of task variables, (length of item, aspect of language omitted, and presence or absence of print), and the effect of experience with the task. The "Copy Cat Task", which could be presented in a print or a noprint mode , was devised to measure metalinguistic awareness in preschoolers . Twenty- two three and four- year- old children were randomly assigned to a treatment and a control group . The Copy Cat Task was administered in print and no- print conditions to all subjects as a pre test and six months later as a post test . The Copy Cat Task, using different items and providing feedback , was administered to the treatment group at one- month intervals. A parallel visual task, which asked subjects to say if two pictures were exactly alike was administered to the control group at six-week intervals . Most subjects were able to accomplish the judgment part of the task with very little experience. Very few subjects were able to accomplish the segmentation part of the task, even with experience. The length of items, the level of language omitted , and presence of print were all significant variables. Children judged phoneme- omitted items most easily but found it most difficult to segment these same items, suggesting that a variety of strategies are used to accomplish metalinguistic tasks. Print was a significant variable in both judgment and segmentation but effected the two tasks differently . A more sophisticated understanding of print was needed for children to use print to segment than to judge . Experience with the task (experimental versus control group) was a significant variable, for the judgment portion though not for the segmentation portion of the task.
Health and illness beliefs and practices of Korean Americans
(Boston University, 1988) Do, Hyunok K
The purpose of this study was to describe the beliefs and practices related to health and illness among Korean Americans from the Korean American layperson's point of view. The study also examined the extent of the retention of these beliefs and practices among the second generation of Korean Americans in comparison with the first generation.
Expert system for the visual recognition of arm movements
(Boston University, 1988) Djermoun, Dris
Based on experience, humans have the ability to anticipate the continuation of a movement after they have seen and recognized part of it. An expectation-driven visual recognition system similarly deals with the problems of having a computer make perceptual predictions of motion. In this work, an expectation-driven expert system for the visual recognition of arm movements is proposed. The system relies on the variations of the joint angles to make predictions and recognize motion. It takes as input the waveforms describing the variations of those angles, segments them at multiple levels and generates symbolic movement descriptions. As the motion continues, it updates the knowledge-base with new motion descriptors and makes use of the information already acquired or inferred to proceed. It uses the initial motion data to classify the movement at hand and the following information to identify it.
