There have been numerous twin-based studies in the past that control for the unobservable variables in the analyses. However, these past studies have often yielded contradictory results with no consensus on some important issues and no definite conclusions. The objective of the present study is an attempt to explain some of the differences in the past studies, and to re-examine some issues on returns to education, the importance of genetic and environmental factors, and the significance of measurement errors. / This study applies four twin-based models to three available US twin data. The empirical results in this study show that (1) while some differences in existing studies are caused by different data used, other differences are due to different models used; (2) the "true" returns to schooling are mostly less than the "overall" returns to schooling, indicating a positive omitted variable bias; (3) the omitted variables are a significant portion, viz. approximately 40%, of the "overall" returns to schooling; (4) these omitted variables, when divided into the genetic and environmental factors, generally indicate that environmental factors have a stronger effect than genetic factors; (5) models with two schooling variables are more prone to measurement error, biasing the estimates more significantly; (6) the measurement error problem in the schooling variable biases the estimates and the magnitude of the bias depends on the data used; and (7) results for males and females are different. / Yung Chor-Wing Linda. / "May 2000." / Adviser: Junsen Zhang. / Source: Dissertation Abstracts International, Volume: 61-08, Section: A, page: 3293. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2000. / Includes bibliographical references (p. 202-205). / Electronic reproduction.

In exercising their professional duties professional planners inevitably impact on the environment. In the past, more often than not, this impact has been allowed to occur without sufficient forethought, and usually to the detriment of the environment. In this research it is proposed that this undesirable state of affairs arises from inadequacies within the professional education of the planners, and that greater emphasis on the environmental education of planners is called for. From the perspective of a participative approach to curriculum development, the opinions of professional planners in the Port Elizabeth area were canvassed to establish baseline data in respect of their environmental education needs. To provide further information and a background against which the perceptions of the professional planners could be assessed, the opinions of the learned societies of the planning professions and of key environmentalists were also sought. In all these opinion surveys postal questionnaires formed the basis of the methodology employed. The extent of environmental education presently available to professional planners at tertiary institutions in South Africa and overseas, with particular emphasis on that available in the civil engineering discipline, was also investigated. The surveys revealed a strongly felt need for environmental education within the planning professions. The natural environment, the social environment, environmental ethics and interdisciplinary action all emerged as acceptable themes of the said education. A number of environmental topics to be covered were also identified. Block-release and part-time courses emerged as the most popular format for such environmental education offerings. The limited environmental education practice within the civil engineering discipline at South African tertiary institutions was noted, and the overseas practice in this regard provided useful insights. The data gathered as outlined above, formed the basis from which proposals towards an environmental curriculum for professional planners were made. Although these proposals focused primarily on the civil engineering discipline within the ambit of technikon-based educational programmes, wider multi-disciplinary applications remained an important concern. In the first instance, proposals aimed at expanding the environmental component of the existing first-qualification course were suggested. Secondly, proposals in respect of a post-first qualification, interdisciplinary, environmental study programme leading to a technikon degree were formulated.

The world of today's higher education organizations is characterized by complexities brought about as a result of rapid change, economic and political turbulence, and increasing global interdependence. The complexity of the environment in which colleges and universities operate is also due in part to a need to serve multiple internal and external constituencies. In order to be more responsive to the demands of its numerous constituencies and at the same time preserve their intrinsic values, colleges and universities need to know how effective they are in what they do. This research asked: To what degree does institutional effectiveness allow public colleges and universities to operate in a sustained manner over a long period of time while meeting the needs of their constituencies? The lack of criteria about what constitutes effectiveness in higher education contributes to the lack of research in this area of organizational theory. This research examined organizational effectiveness and its measurement in higher education environment using a survey of multiple internal and external constituencies. The purpose of the survey was to gather information regarding participants' perceptions about educational outcomes, processes, and environment in higher education organizations. In addition, given the changes in how higher education institutions are financed and the potential implications of these changes for effectiveness, this research explored the degree to which resource dependence, primarily dependence on public funding, influences the effectiveness of public colleges and universities. To address these questions the research tested the applicability of the sustainability framework as a model of effectiveness in higher education. The study suggests modification of the elements of the sustainability and extends the use of the concept of environment as it is defined in the sustainability framework to the concept of environment as defined in organizational theory. The sustainability framework has not been tested in this way before. The results indicate that there is promise in using the sustainability framework in this modified form and suggest that this concept is worthy of further exploration. Additionally, the study examined the role of multiple constituencies in defining effectiveness in higher education. The findings indicate that there are significant differences in perceptions of effectiveness among the groups of constituencies examined in the study. Finally, the results suggest that sources of public funding and the amount of money institutions spend per student have an influence on some aspects of effectiveness. To examine this further, the study explores the role of the political and fiscal environment in which institutions of higher education operate and offers institutional theory as a basis to explain resource dependence in public higher education. The findings of this study contribute to the field of organizational effectiveness, aid in understanding the role that public funding plays in higher education effectiveness, and contribute to the field of organizational theory more generally.

As the human population increases, it becomes increasingly more important for society to understand the impact of humans on the environment. Preserving fixed resources by engaging in sustainable practices is necessary to ensure those resources are available for future generations. Since the early 1960s, policy makers and educators alike have sought to ensure that students graduate environmentally literate. Previous research has identified a multitude of barriers that limit classroom teacher’s ability to integrate environmental education into their curriculum. The purpose of this study was to investigate how teachers overcome those barriers that restrict the integration of action based environmental education into the public school classroom. This was a three case study of public high school teachers. Data were gathered for this qualitative study through observations, interviews, and the collection of documents. Constant comparative method was utilized to analyze data. The researcher conducted a within-case analysis for each case and a cross-case analysis as well. Through the use of coding, the researcher identified patterns and themes across cases. Barriers identified by participants included resources, time, and risk. The primary factors uncovered by this study, which potentially affect teacher efficacy, are personal and educational background, the availability of mentors, and support of outside agencies. The implications for policy makers and institutions of higher education that can be drawn from this study are that, through the course of teacher undergraduate and graduate education, teachers should be provided with field experiences in the area of environmental education. In addition to providing field experiences, finding ways to link teachers to outside environmentally focused agencies and mentors increases teacher efficacy by providing support and resources.

Informed by post-humanism, my research examines the entanglement of more-than-human forces at the Bread Loaf School of English. The oldest professional development institution of its kind, the Bread Loaf School of English has invited teachers to spend six-weeks each summer studying at its mountain campus since the summer of 1920. When the physical campus was forced to close indefinitely on the eve of its one-hundredth anniversary at the start of the pandemic, the loss of this physical space prompted meditations on over a century of institutional tradition as teachers shared their stories of the mountain campus. Bread Loaf’s landscape is teeming with narrative—stories that blossom like wildflowers each summer before fading with the coming winter. Within those narratives, like the Deleuzoguattarian “orchid and wasp,” the human and non-human transform one another in an intra-active entanglement of bodies. What happens when we pause and attempt to follow the threads of these entangled narratives in order to better understand how more-than-human bodies meet, collide, and contaminate one another over time to constitute the assemblage of the Bread Loaf School of English? The rich tapestry that begins to unfold offers a model for more-than-human storytelling well beyond the mountain, spanning the manifold landscapes teachers return to at the end of the summer.
