It is the purpose of this research to examine the interactions between organizations and the work of coordinating agencies in influencing those interactions using social exchange theory. A model was developed, incorporating elements of exchange theory, and the components of that model examined in the community. Techniques of change and the outcomes of activities of the coordinating agency were examined in an effort to develop a "case study" of a coordinating agency's activity in the community. Historically, social services were provided in the community through informal, often familial, networks. With the urbanization of society, social services have become more formalized and specialized with a remarkable increase in the number of individual agencies. Movement from a "growth" to a scarcity economy and new federalism as well as concern with duplication, overlap, and gaps in services have led to an interest in the coordination of these activities. The Area Agency on Aging, considered by many to be a forerunner to the Allied Services Act, was implemented in 1973 by the federal government for the purpose of coordinating services to the elderly in the community. The goal of the Area Agency is the development of a comprehensive coordinated community service system. The activities of six such coordinating agencies as well as the social service organizations in their areas were studied to determine the explanatory value of social exchange theory. Additionally, attitudes of service providers toward various tactics for community change as well as the perceived outcomes of coordinating agency activities were investigated. The study of the Area Agency on Aging as a coordinating agency in the community was accomplished in two waves of data collection. The first, consisting of indepth interviews with 84 individuals in six areas, took place from May through July of 1975. The second wave involved indepth interviews and a mailed survey. Data were collected from 191 individuals in 126 agencies in three areas, urban, rural and urban/rural mixed. The data were coded and analyzed by computer to determine trends and relationships. The interview schedules were analyzed for specific cases. These objective and subjective data were used to "reconstruct" this study of interaction and coordination. A model, Organizational Interaction Model, was derived utilizing social exchange theory. This model contains the elements of commodities: funding, information, access to influentials, clients, staff and technology; valuing criteria: integration, status, world view, autonomy, domain and power; and arenas of exchange: planning, contracts and letters of agreement, hearings and meetings, evaluation and monitoring, and client transfers. These elements were examined, and their explanatory value for activities in the community involving organizations and coordinating agencies was determined. Change techniques, involving varying types as well as levels of intervention, were studied in terms of their perceived appropriateness by community organizations. The data suggested changes in activities of coordinating agencies, social planners, and makers of policy. Perceived outcomes of coordinating agency activity over the past three years show positive impacts in the community generally, though individual impacts vary. Finally, the implications of these findings are discussed for coordinating agencies as well as local and federal policy makers, with suggestions for future research. Social exchange theory offers rich ground for the study of community service systems and the coordination of interactions within corrrnunities.

This study is an attempt to discover the intercultural communication problems and the methods of coping used by the Nigerian students in the Portland metropolitan extent to which these discovered problems and tried solutions compare with those of other international students that are commonly reported in the literature.

The research problem that the thesis is concerned with is the definition of the components of the "attractiveness" of a regional shopping center as they pertain to the decision-making process of the consumer. In addition, variations among the shopping patterns of male and female shoppers and among income groups are examined.

Urban ecological problems have hitherto been addressed using one of two major approaches. The first has a social impetus directed at ethnic, economic and family characteristics and their relationships with the spatial distribution of urban residential housing. The second approach emphasizes the influence of the physical environment and the services available to subareas. The sociological method has had much more attention in modeling applications than the physical analytic technique. This study adopts the physical approach with a focus that is emphatic on infrastructural factors and land attributes, and their influence on the differential rates of fringe area residential growth in the Portland metropolitan region. Data were acquired through direct research supplemented by building permit records, jurisdictional estimates, and information from the 1970 and 1980 u.s. Censuses. Growth functional relationships were operationalized using housing starts and residential land conversion as two dependent variables against which the explanatory factors of infrastructure (water and sewer), land characteristics, road network density, accessibility, and social factors were regressed in recursive models over three subperiods in the decade 1970-1980. Five models were derived for the SMSA and the four counties for the decade, and three more subperiodic models for each area, for the categories of housing starts and land conversion. The derived models were tested against a standard econometric technique (Chow test) to verify the consistency of the coefficients (elasticities) over the different subareas in the four time periods. The results showed extremely high levels of significance of the Chow tests, deeming it necessary to examine the behavior of the elasticities in more detail over space and time. The results of the examination verified that the performance of infrastructure variables were highest in Washington County, while accessibility and road network density showed very high performances in Multnomah County. Land attributes were most notable in Clark County, while income elasticities were equally high in Multnomah, Washington, and Clark Counties. The lag effects of residential development in the immediate anteceding period were more important in Multnomah and Washington than in other counties. In Clark County, residential development in the early part of the decade was the only significant lag variable in models of the latter part of the decade. The conducted tests lend adequate support to the postulated hypotheses. In general, there was differential response to the selected attributes in the subareal models. Also, the results and tests confirmed that parameter estimates of attributes varied in different governmental jurisdictions. This implies that the counties placed different emphasis on the tested variables. Where the favorable set of variables was emphasized with one major sewer service district (Washington County), fringe area growth was enhanced. The emphasis of congestion-related variables (Multnomah County) without the desired infrastructure resulted in a relatively reasonable decline in fringe area residential housing.

La investigación del espacio doméstico, espacio privado y espacio público son temáticas centrales en el desarrollo de la sociología, por sus implicancias en las relaciones de género y, de manera específica, por que posibilitan una mayor comprensión de la naturaleza de la sociedad peruana. El propósito de la tesis es analizar las transformaciones en las relaciones de género en el proceso de redefinición del espacio doméstico, la construcción del espacio privado y la conquista del espacio público, con sus mutuas interrelaciones, en las mujeres de los sectores populares de Lima Metropolitana. La investigación se fundamenta en las declaraciones que elaboran las propias mujeres de los sectores populares sobre su participación en los ámbitos doméstico, privado y público. Para ello se desarrolla un estudio cuantitativo que permitió conocer las principales tendencias del comportamiento femenino en las dimensiones de la vida social. El estudio se basa en la realización de una muestra probabilística de 494 mujeres encuestas en los asentamientos humanos de Lima. / Tesis

Since the start of the COVID-19 pandemic in December 2019, much research has been done to develop the spatial-temporal methods to track it and to predict the spread of the virus. In this thesis, a COVID-19 dataset containing the number of biweekly infected cases registered in Ontario since the start of the pandemic to the end of June 2021 is analysed using Bayesian Spatial-temporal models and Area-to-area (Area-to-point) Poisson Kriging models. With the Bayesian models, spatial-temporal effects on infected risk will be checked and ATP Poisson Kriging models will show how the virus spreads over the space and the spatial clustering feature. According to these models, a Shinyapp website https://mujingrui.shinyapps.io/covid19 is developed to present the results.
