The major hypothesis of this paper is that any deviance in syntax present in oral language will be evident in oral r eading behaviour. Using Lee and Canter's Developmental i 1 Sentence Scoring technique (1971) and Y. Goodman and Burke's Reading Miscue Inventory (1972) linguistic competence was established in t hree male children. ages 10 to 11. patterns of strengths and weaknesses in reading were determined. and the relationships t hat were established, were examined. Results of the study i ndicate that oral language behaviour is closely tied to oral r eading behaviour. This type of approach can be used as a basis for a diagnosis of a reading difficulty and then a prescription for language and reading skills.

The objective of this investigation was to clarify the adaptive significance of female sexual behaviours in the house cricket, Acheta domesticus, and the Texas field cricket, Gryllus integer. Experiments were focussed primarily on: nutritional factors affecting female reproductive success; the ontogeny of female sexual behaviours; female mating frequency and progeny production; and the pattern of sperm competition. Reproduction of singly mated female A. domesticus assigned to 3 nutritional regimes was compared . Females fed a vitamin and protein-enriched mouse chow, cannibalistic females, and starved females produced on the average, 513 , 200 and 68 offspring, respectively. Cannibals probably could not obtain the same amounts of essential nutrients as females fed mouse chow. Reabsorption of oocytes was likely the major factor contributing to the decreased reproduction of starved females. In addition, female !. domesticus fed mouse chow, but allowed constant access to males produced 11 times as many offspring than did females fed corn meal. Females fed corn meal probably could not absorb or synthesize enough dietary lipids, thus resulting in poor ovariole growth. Female !. domesticus first mate at an average adult age of 7 days, closely corresponding to when they first exhibit positive phonotaxis. Females mate repeatedly and often consume the externally attached spermatophore. In ~. domesticus, females allowed constant access to males produced significantly more offspring than did single maters. Similarly, doubly mated G. integer females produced more offspring than did single maters. This difference resulted largely from the failure of many single maters to reproduce. Remating by female crickets partly functions in offsetting the possibility of a failed initial mating. Nymph production increased significantly with the time the spermatophore was attached in singly mated ~. domesticus. Spermatophore consumption by the female was not affected by male guarding behaviour, and the interval between mating and eating of the spermatophore may often be shorter than the time required for maximum insemination. Some degree of sperm depletion in singly mated !. domesticus and G. integer may have occurred. The patterns of daily offspring production of singly and multiplymated females suggests that a factor provided by a male during mating stimulates female oviposition and/or egg production. Female crickets also might acquire nutrition from spermatophore consumption, a benefit that is augmented by female multiple mating. The electrophoretic examination of various allozymes in ~. integer did not permit determination of a pattern of sperm competition. However, the possibility of last male sperm predominance is related to male guarding behaviour.

Research into organizational behaviour has indicated that there is an inevitable conflict between the needs of the individual and organizational demands. Psychologists have given insights into basic individual needs and contend that satisfaction of these needs constitutes a motivating force which enhances desired behavioural patterns. Behaviouralists have suggested that a basic and pervasive individual need is the culturally determined need for privacy. Anthropologists and environmental psychologists have shown that man's spatial behaviour is observable and predictable and that changes in the physical environment or the way it is perceived are accompanied by concommitant changes in behaviour. Research findings from each of the disciplines have been reviewed in an attempt to show that the physical environment is a significant factor in satisfying the needs of the individual organizational member, hence, a significant influence on organizational behaviour. A model has been generated to show the relationship between the physical setting and behaviour and to underscore the importance of making provisions within the physical setting for the attainment of a culturally determined optimal level of privacy. The physical setting, by providing for this need, becomes a significant factor in reducing the conflict between the individual and the organization and makes for acceptable role behaviour and the fulfilment of organizational goals.

Previous research has shown that the stress hormone corticosterone can increase depressive and anxiety-like behavior in rats as well as dampen the HPA response to a novel stressor (Kalynchuk et aI., 2004; Johnson et aI., 2006). Several studies have also shown that adolescence is a period of increased sensitivity to the negative effects of stressors (reviewed in McCormick et aI., 2010), which are often the result of exposure to corticosterone, and yet there is no research to date examining the effects of corticosterone administration during adolescence. The purpose of these experiments is to determine both the immediate and enduring effects of prolonged exposure to corticosterone in adolescence and adulthood on anxiety-like behavior, depressive behavior, and the HPA response. In Experiment 1 adolescent and adult rats were administered an injection of 40 mg/kg of corticosterone or vehicle daily for 16 days. Ha l f of the rats were then tested on the elevated plus maze (EPM) one day after their last injection, and the following day were tested on the forced swim test (FST). After the FST, which is a stressor, blood samples were collected at three time points, and the plasma concentrations of corticosterone were determined using a radioimmunoassay. The remaining rats were left undisturbed for three weeks, and then underwent the same testing as the first group. Corticosterone treatment had little effect on anxiety-like and depressive behavior, but it did alter the HPA response to the FST. In those rats tested soon after the period of injections, corticosterone dampened the HPA response as compared to vehicle treated rats in both adolescent and adult treated rats. For the adolescent treated rats that were tested several weeks later, corticosterone treatment increased HPA response as compared to the vehicle treated rats, but the same was not true for the adult treated rats. I t was hypothesized that the lack of behavioral effects of the corticosterone treatment may be the result of the vehicle injections inducing a stress response and thereby both groups would have similarly altered behavior. In Experiment 2 rats were administered corticosterone dissolved in their drinking water with 2.5% ethanol, or jus t the 2.5% ethanol or plain water, to determine the effects of corticosterone treatment without a stressor present. The regular drinking water was replaced with treated water for 16 days either during adulthood or adolescence, and as before, rats were either tested in the FST one day after the water was removed or three weeks later. Again there was no effect of treatment on depressive behavior. Similar to what was observed in Experiment 1, corticosterone treatment dampened the HPA response to a stressor for the rats tested soon after the treatment period. However, in Experiment 2 there was no effect of treatment on HPA response in those rats tested several weeks after they were treated. These results indicate that corticosterone can have a lasting effect on the HPA when administered in adolescence by injections but not in drinking water, which is likely because of the different schedules of exposure and rates of absorption between the two administration methods.

Consumption values and different usage situations have received extensive interest from scholars; however, there is a lack of understanding regarding how these two constructs interact when it comes to the purchase decisions of consumers. This study examines the relationship between consumption values, consumption situations, and consumers’ purchasing decisions in terms of their willingness to pay and the purchase quantity. First of all, my model proposes that all four consumption values and different situations have a positive effect on consumers’ willingness to pay as well as the quantity they purchase. It also proposes that varying usage situations moderate the effect of consumption values on consumers’ purchasing decisions. In my conceptual model, I have also integrated the epistemic and conditional values where there is a gap in the existing literature. Prior literature has isolated the consumption values when studying how they affect consumer behavior and has not examined how consumption situations moderate the relationship between consumption values and purchasing decisions. Also, the existing literature has mostly focused on how consumption values affect purchase intentions, brand loyalty, or satisfaction, whereas my study focuses on purchasing decisions. For my study, the participants were randomly chosen from the general wine consumer population and the age range was between 20 and 75, which included 83 male respondents and 119 female respondents. The data received from my respondents support my hypotheses for the model. In my final chapter, I discuss the theoretical and managerial implications as well as suggestions for future research.

While many studies have been conducted on adolescent depressive symptoms and alcohol use, much of the research has examined these behaviors separately rather than examining their co-occurrence within individuals. In the present study, adolescents (N = 4412; 49% female) were surveyed at four time points (grade 9, 10, 11, and 12) and growth mixture modeling was used to identify groups of individuals reporting various patterns of depressive symptoms and alcohol use across the high school years. Four groups were identified, including co-occurrence (higher depressive symptoms and higher alcohol use relative to peers, comprising 6.1 % of boys and 7.1 % of the girls in the sample), pure depressive symptoms (higher depressive symptoms and lower alcohol use; 12.7% of boys and 12.5% of girls), pure alcohol use (higher alcohol use and lower depressive symptoms; 20.9% of boys and 19.9% of girls), and low co-occurrence (lower depressive symptoms and alcohol use, 60.3% of boys and 60.5% of girls). Groups were compared on self-regulatory (i.e., delay of gratification) and approach behaviors. For both boys and girls, delay of gratification was the strongest predictor of group membership, with the co-occurrence group scoring the lowest and the low co-occurrence group the highest. This finding emphasizes the importance of assessing delay of gratification in the identification of high risk youth.
