Merger Type and Performance: A Longitudinal Study of the Food and Kindred Products Industry (open access)

Merger Type and Performance: A Longitudinal Study of the Food and Kindred Products Industry

The purpose of this study was to measure merger performance on a longitudinal basis using a micro perspective. Specifically, this study looked at the performance of a sample of mergers drawn from the food and kindred products industry, Standard Industrial Classification code 20, for a period of five years before and five years after the merger using two performance measures. The performance measures, namely market returns to stockholders and return on investment, have been used extensively in the literature to study the performance of mergers and acquisitions, albeit on macro samples. The study offered significant statistical support for the hypothesis that mergers benefit the acquiring firm and its stockholders, as well as for the hypothesis that merger performance in the latter time period of study (1977 to 1984) was better than in the former (1968 to 1977). However, no significant difference in performance was found across merger types. The study discussed the managerial implications of these findings and offered directions for future research in the area of merger performance.

A Descriptive Analysis of Good Readers' and Writers' Concepts of Authorship at Grades Six and Eight (open access)

A Descriptive Analysis of Good Readers' and Writers' Concepts of Authorship at Grades Six and Eight

This qualitative research study examined the concepts of authorship exhibited by twelve selected good readers and writers in grades six and eight. Data were collected during pre-writing session interviews, five hour-long writing sessions, and post-composition interviews, and from written compositions and questionnaires. The following conclusions were drawn from the study. School and home reading programs that emphasized children's literature selections and regular and wide-ranged reading practices directly influenced the subjects' writing behaviors and concepts of authorship. In addition, those students who performed strongest as authors were those who found time to write privately at home or in a home-like situation. Revision occurred in traditional ways, such as movement or deletion of text, but also appeared to be related to the subjects' personal writing styles, such as verbalization, mental outlining, or reading the text out loud. Both grade levels exhibited individual writing development through integration of experiences, knowledge, and physical and social maturation. For these young writers, the key factor in perceived authorship was whether a writer had an interest in and enjoyed writing.

Transactional Risk Factors and Coronary Atherosclerosis: The Impact of Type A Behavior, Hostility, and Defense Style (open access)

Transactional Risk Factors and Coronary Atherosclerosis: The Impact of Type A Behavior, Hostility, and Defense Style

The relationship of coronary-prone behavior, hostility, and defense style to atherosclerosis was examined. Subjects were 1,271 patients who underwent coronary angiography at Duke University Medical Center between 1974 and 1980. Type A behavior was assessed using both the Structured Interview and Jenkins Activity Survey. The Cook and Medley Hostility scale and Byrne's Repression-Sensitization scale, both subscales of the Minnesota Multiphasic Personality Inventory, were employed to measure hostility and defense style. The results revealed no significant association between the disease end-points CADSEV, history of myocardial infarction, and history of angina pectoris and either the Structured Interview Type A, hostility, or repression-sensitization, Jenkins Activity Survey defined Type B's, however, were found to more frequently complain of angina. It was suggested future research employ longitudinal or process designs to focus on adaptive functioning from a transactional and developmental perspective which may serve to promote coronary resistance.

Solution Studies of ⁶Li Enriched Organolithium Compounds Using New NMR Techniques (open access)

Solution Studies of ⁶Li Enriched Organolithium Compounds Using New NMR Techniques

With the values of 6Li T1 measured and the literature values of J(13C-6Li) for these compounds, three new 13C NMR techniques are developed for the analysis of organolithium compounds. Modifications to the spectrometer are discussed, as well as calibrations of the 6Li decoupler channel needed to set up these new experiments. The theoretical development of each technique is presented, as well as data from their verification, using organolithium compounds of known structure. Once qualified, the new experimental techniques are used to analyze a series of alkyllithium / lithium alkoxide mixed aggregates in solution, where structures and values of J(13C-6Li) may not be known. The combination of Ti relaxation measurements and 13C{1H, 6Li} triple resonance techniques serves as a means of determining the structure of organolithium aggregates in solution.

Validation of the Ecological Q-Sort: A Self-Concept Instrument for Use With Elderly Persons (open access)

Validation of the Ecological Q-Sort: A Self-Concept Instrument for Use With Elderly Persons

The Ecological Q-Sort was developed specifically for the measurement of self-concept in older adults. Self-concept is defined as individuals' perceptions of themselves in relationship to their environment. Consequently, self-concept is contextual, multidimensional and varies with the situation. The Ecological Q-Sort was subjected to convergent and discriminant validational procedures in the present study. Correlational analyses provided support for both convergent and discriminant validity, suggesting that this instrument measures ecological, domain specific self-concept in older persons. However, multivariate analysis of variance did not yield significant main effects or interactions for sex, marital status, and health as observed on the sets of ecological and non-ecological self-concept measures.

Quality Assurance Practices by Indian Manufacturing Organizations: A Conceptual Framework and an Empirical Investigation

The purpose of this study is three-fold. First, based on the synthesis of literature on quality concepts, critical factors that must be practiced to achieve effective quality management in an organization were identified. A framework to be used by organizations to evaluate their quality assurance practices were developed. Second, a field survey was conducted to identify the degree to which quality assurance is being practiced in Indian Manufacturing organizations and to locate the organizational areas where better management control can make the quality assurance system more effective. Finally, an attempt was made to develop models that could be used to forecast the level of quality achieved.

The Effect of Ropes Course Elements on Self-Concept and Affective Behavior

The purpose of this study was to investigate the effects of a ropes course program on self-concept and affective behavior, based on the belief that ropes course participants would rate significantly higher than non participants. A group of freshmen from a select liberal arts college made up the population. Measuring instruments used were the Tennessee Self-Concept Scale and the Platt Affective Behavior Scale. The program was a pre-test, post-test control group design. Data were analyzed by two sample t-tests, correlations, and logistic regressions.

The Effect of Seat Back Angle on Responses During Recumbent Cycling (open access)

The Effect of Seat Back Angle on Responses During Recumbent Cycling

The purpose of this study was to evaluate metabolic, cardiorespiratory, and perceptual responses during recumbent cycle ergometry performed at various seat back angles and different work rates. Healthy college-aged men performed steady-state exercise at two work rates, 100 watts (n=46) and 150 watts (n=26), using five back seat angles, 90, 105, 120, 135, and 150 degrees. The results of this study suggest that recumbent seat back angles of 135 to 150 degrees are associated with lower metabolic and cardiorespiratory stress during rest and submaximal exercise than more upright positions. The reduced stress at these angles is accompanied by lower perceptions of exertion and improved seating comfort. The failure of the base-line correction for resting V0 2 to remove the effect of seat back angle implies that the reduced physiological stress associated with these positions is due to reasons other than attenuated resting metabolic costs. It is concluded that the selection of recumbent seat back angles between 135 and 150 degrees can result in improved efficiency, reduced physiological stress, diminished perceptions of exertion, and increased seating comfort.
