The effects of the outdoor experiential ropes course on perceived team performance

The purpose of this quasi-experimental study was to explore the perceived effects of the Ropes Course on the performance of intact work teams. The dependent variable, team performance, was measured by the Team Performance Assessment, a 20 question inventory. The Ropes Course, the independent variable, was an outdoor experiential training program presently marketed as a highly effective team building training program. Issues the team addressed in the highly emotional and physical environment were purported to transfer back to the work environment and act as a catalyst for change The Ropes Course in this study consisted of a day long series of outdoor mental, emotional and physical exercises addressing the issues of goal-setting, role expectations, accountability, trust, respect, communication, problem-solving and decision-making. The 68 subjects, 37 in the treatment group and 31 in the control were employees of a large international financial institution. They were not chosen by random selection. The work teams' managers recognized a need to improve team morale, performance and functioning due to corporate reengineering and downsizing resulting in team members' job losses. Control teams were partially matched to the treatment teams on the basis of professional composition and similar job descriptions. The pretest of the Team Performance Assessment was given the morning of the Ropes Course treatment and the posttest was given three to five weeks later. The control teams received the pretests and posttests at about the same time intervals at their work location but received no Ropes Course treatment. The treatment teams' scores and the control teams' scores were statistically compared using the Multivariate Analysis of Variance (MANOVA) and the Multivariate Analysis of Covariance (MANCOVA) at the .05 level of significance. The statistical analysis revealed a significant difference between the control and experimental teams after the team building Ropes Course training as measured by the Team Performance Assessment (Gilbert, 1996). ^

The empire beats on: Oyo, Bata drums and hegemony in nineteenth-century Cuba

The Lukumí people of Cuba, currently known as Yoruba, are descendants of one of the mightiest West African kingdoms, the Oyo, Empire. The Oyo-Yoruba were important cultural contributors to certain areas of the New World such as Cuba, Brazil, Trinidad, and to some degree Haiti and the Lesser Antilles. Anthropologist William Bascom has said that “no African group has had greater influence on New World culture than the Yoruba.” ^ After the devastation of the empire around 1825, two new Oyos resuscitated. The first, New Oyo, was established about 80 miles south of the ancient site around 1830. The second Oyo was instituted on the other side of the Atlantic Ocean, in the city of Havana and its surrounding towns. Much of Oyo lie, as ancient Oyo is now called, was transported to the New World, reformed and adapted according to its new surroundings, and, it preserved its reign over its “subjects” through the retention and dissemination of its cultural and religious practices. ^ Using an interdisciplinary approach, this investigation will argue that of all the African groups brought to Cuba, the Oyo-Yoruba were the most influential in shaping Afro-Cuban culture since their introduction in the nineteenth century. The existence of batá drums in Cuba and the cultural components of this musical genre will serve as one of many examples to illustrate the vitality of Oyo cultural hegemony over Afro-Cubans. It is arguable that these drums and the culture that surrounded them were very important instruments used by the Oyo to counter the acculturation of many Africans in Cuba. Likewise, this culture became acculturative in itself by imposing its religious world views on non-Oyo ethnics and their descendants. Oral histories and narratives collected among Lukumí practitioners on the island and abroad have been invaluable archives to supplement and/or complement primary and secondary sources of information. ^

A qualitative case study of teacher perceptions and concerns during the implementation of literacy folders in a select elementary school in Broward County, Florida

Classroom teachers are often required to implement new procedures or practices in response to local or federal education mandates. Attempts to implement innovations, often do not take into account the personal side of change; the perceptions, concerns and needs of those required to implement the innovation. One innovation that was required by the School Board of Broward County, Florida for all elementary classroom teachers was the implementation of Literacy Folders. ^ This study attempted to address the personal side of change by identifying teacher concerns during the implementation of Literacy Folders in a select elementary school in Broward County Florida. The Concerns Based Adoption model (CBAM) for change was used as the conceptual framework for this qualitative case study. ^ Sources of data for this study included participant interviews, observations and analysis of documents. Informal conversations with the participants and unscheduled classroom visits were also sources of data. Seven classroom teachers were interviewed using a predesigned interview guide developed based on the CBAM of change, specifically the Stages of Concern Dimension. Participant responses were coded into two categories, (a) recollections of past perceptions, and (b) present perceptions regarding the innovation. ^ Data analysis resulted in the emergence of one major theme and two subordinate themes. The themes were related to time and purpose of the innovation. The researcher also discovered that the participants exhibited responses typically representative of the CBAM for individuals who are in the process of adjusting to a new innovation. ^ Recommendations based on participant concerns are made for improving the implementation of the innovation. Recommendations for alternatives to the innovation and suggestions regarding areas for further research in the field of educational change are also made. ^

A study of leadership behaviors for Breaking Ranks leaders in public secondary schools

This research will investigate what it will take to develop principals who will embrace the recommendations of reform as proposed by National Association of Secondary School Principals (NASSP, 1996) in the Breaking Ranks document. Breaking Ranks is based on the belief that it is within the dynamics of the school culture that principals must gain insight into strategies for improving the schools for which they are held responsible. Given this context, it is important to examine perspectives that are held by principals who lead schools that embrace the concepts of reform as proposed by NASSP, thereby, could be deemed “Breaking Ranks” schools. It is within these schools that the new role of the principal develops. NASSP has identified seven key recommendations for leadership development; “attributes that need nourishing” (p. 12) for the success of school reform. The seven recommendations are included in Breaking Ranks. ^ The purpose of this study is to identify and describe how principals put the seven recommendations into practice as they function in their schools. In addition, this study will gather information on the characteristics, support, skills, and training these principals identify as critical aspects and components of their success. This is a study of principal leadership at four high school sites where “Breaking Ranks” principals have been identified. ^ This research plan will be designed to utilize an inquiry-based process with a panel of experts and four “Breaking Ranks” principals. This study will describe: (1) how a panel of experts identify what they believe needs to be done in order to put the recommendations of the Breaking Ranks document into practice and their identification of principals who are breaking ranks; (2) how identified principals say they have been able to put the recommendations of the Breaking Ranks document into practice; (3) How both groups identify and describe: (a) the characteristics and behaviors of a “Breaking Ranks” principal; (b) the new leadership skills as described by the seven recommendations identified in the Breaking Ranks document; (c) the support necessary in order to meet the recommendations in the Breaking Ranks document; and (d) The training needed in order to become “Breaking Ranks” principals; and (4) how the process of creating “Breaking Ranks” principals can be described by experts who have studied it theoretically and principals who have demonstrated it in their schools. ^

Big city days: Race and labor in early Miami, 1914--1925

The purpose of this study was to recast Miami's social history during the first three decades of the twentieth century through an examination of working class life. The thesis attempts to fill a gap in the literature while also expanding on the advances made in race and class studies of the United States. Through an analysis of local newspapers, minutes of a carpenter's union, and other archival sources, the thesis demonstrates how white workers obtained a virtual monopoly in skilled jobs over black workers, particularly in the construction industry, and exacted economic pressure on business through the threat of work stoppages. Driven by the concern to maintain smooth and steady growth amidst a vibrant tourist economy, business reluctantly worked with labor to maintain harmonious market conditions. Blacks, however, were able to gain certain privileges in the labor market through challenging the rigid system of segregation and notions of what constituted skilled labor. The findings demonstrate that Miami's labor unions shaped the city's social, cultural, and political landscape but the extent of their power was limited by booster discourse and the city's dependence on tourism. ^

The exploration enhancement workshop: An exploration-based approach to facilitating identity formation in young adults

This dissertation reports an investigation of the utility of two intervention programs to facilitate identity formation by way of exploration, one designed from an explicitly self-construction point of view and the other designed from an explicitly self-discovery point of view. The self-construction program was implemented using cognitive skills and orientations derived from Berzonsky (1989), Grotevant (1987), and Kurtines (1999). The self-discovery program was implemented using affective insight development strategies derived from Csikszentmihalyi (1990), Maslow (1968), and Waterman (1990). Three sets of measures were used: (a) cognitive identity measures, (b) affective identity measures, and (c) overall identity measures. Ninety undergraduates from Florida International University completed the intervention. Participants were assigned to one of three intervention conditions (Cognitive, Affective, and Control) and were pretested and posttested on cognitive, affective, and overall identity measures. Intervention strategies were introduced and discussed in the context of specific goals and choices that participants brought to group. Intervention results were then analyzed in terms of the effectiveness of the intervention conditions in promoting their respective developmental domains. The intervention was effective in promoting identity development in comparison to the control condition, with the cognitive condition facilitating cognitive competence and the affective condition facilitating affective insight. Results are discussed in the context of the constructivist and discovery perspectives, as well as in light of the broadened view of exploration offered in this paper. ^

World coffee markets and national coffee parastatals since 1989: A comparative study of Colombia and Cote d'Ivoire

The International Coffee Agreements (ICA) involved the majority of nations producing and consuming coffee and provided relative economic stability to the coffee sectors of the exporting Third World countries. This study focuses on the serious impact of the 1989 collapse of the ICA on the domestic coffee sectors of Colombia and Côte d'Ivoire. In particular, the dissertation examines the role of the Colombian and Ivoirian coffee parastatals, the Federacion Nacional de Cafeteros de Colombia and the Caisse de Stabilisation et Soutien des Prix des Produits Agricoles, during the crisis and their transformation by it. ^ The theoretical framework employed in this study is borrowed from the literature on state-society relations. The methodology includes: in-depth analysis of the historical roles of the parastatal agencies in coffee production, state-society relations and economic development in Colombia and Côte d'Ivoire; interviews with parastatal administrators, producers and other knowledgeable informants in both countries; and a comprehensive review of newspaper articles and official statements of coffee policy published in Colombia and Côte d'Ivoire. prior to, during, and after the crisis. ^ The Colombian and Ivoirian coffee sectors and their producers faced serious economic and social problems following the drop in coffee prices. The coffee parastatals in Colombia and Côte d'lvoire first lost some of their responsibilities following the world coffee crisis. The Caisse was in the end eliminated while FEDECAFE struggled to remain in existence. Along the way, both entities faced protests from disgruntled coffee producers, who organized politically for the first time in their nations' histories. I argue that the outcome for the parastatals depended in part on the conditions of their formation, particularly the level of societal involvement in their creation. I also posit that the country's dependence on foreign aid played a key role in the fate of the parastatals. ^ This dissertation concludes that developments in the Colombian and Ivoirian coffee sectors have significantly contributed to the creation of the difficult political and economic conditions of both countries today. ^

Health care utilization behavior of elders in a multicultural urban environment

The objective of this research is to determine the influences of social, environmental, behavioral, and economic forces on the health care service utilization of four racial/ethnic groups of non-institutionalized elders in a multicultural urban environment. To address these issues this dissertation examines three intertwined themes of culture, aging, and health, using a sample of elders residing in Miami-Dade County, FL in four racial/ethnic groups: white non-Hispanic; black non-Hispanic English speakers; Cuban; and non-Cuban Hispanic. ^ The research questions were analyzed using both quantitative and qualitative data. Data for the quantitative component uses telephone survey data from the Dade County Needs Assessment. The purpose of this component is to develop a more comprehensive model of elder health care utilization behavior. The qualitative component uses data from focus groups from Dade County Needs Assessment, archival data and a literature review of previous ethnographic research. The purpose of this component is to gain a better understanding of the social construction of the terms “age”' and “aging,” as well as to place issues of health and health care in the lives of elders. ^ The findings raised several important issues. First, just because people share a common chronological age does not mean that they are the same in every other respect. Examining elders as a homogeneous group of users of formal health care services in a community is simplistic. Placing “aging” and “health” in a cultural context is important. My findings confirm that the meaning of “aging” and “old” are socially constructed. Further, the term “aging” is NOT synonymous with ill health or frailty. This was a consistent finding in both the quantitative and qualitative results. ^ While all aging individuals share a mutual orientation toward aging (i.e., biological process), they do not age the same way (i.e., social construction of “aging”). Thus, policymakers and others serving the elder population must be aware of the particular cultural context, as well as the previous life experiences of the individuals that they serve. This analysis documents the importance of culture and geographic community in understanding health care service utilization of elders. ^

Voices at the shore: Ethnolinguistic identity among adolescent Haitian students

Newly immigrated Haitian adolescent students enrolled in the Miami-Dade Public School System and designated as Limited English Proficient (LEP) face many challenges as they adjust to new expectations for performance and success in the family, school, and community. The dissertation examines the emerging self-identities of 32 Haitian LEP students attempting to fit in and succeed within the classrooms and larger community of Miami. Research questions asked include (1) What models for self-identity, including education and careers, are postulated for young Haitians? (2) What are the discourses and cultural models through which these identities are expressed? (3) How does the school assign identities to Haitian students? (4) How do the notions of identities conflict? and (5) How do emergent identities affect the students, orientations, adaptation, and performance in the worlds of secondary and higher education? ^ Research was conducted longitudinally over a three-year period (1996–1999) within the Miami-Dade Public School System and within the Miami Haitian community. Research methods included ethnographic research (participant and nonparticipant observation); interview; collection of oral histories; focus groups; and the examination of school records (grades, attendance, test scores). ^ The findings suggest that despite pressures from school and peers many Haitian students maintain a strong ethnolinguistic identity that provides the means to maintain an ideal “student” identity even as it conflicts with the American school Is negative marking of the LEP students I social background, culture, and language. The label “limited proficient” also limits the Haitian students' access to strong remedial or advanced academic programs and hence to future opportunities. ^ In conclusion, it is recommended that a re-working of the ways Haitian immigrant students are identified, tested, counseled, and advanced to other academic programs is necessary. ^

The recruitment process of the Shining Path and MRTA guerrilla groups: A political psychological perspective

This thesis is an analysis of the recruitment process of the Shining Path -SP- and Revolutionary Movement “Túpac Amaru” -MRTA- guerrilla groups. Although SP was considered more aggressive, it gained more followers than MRTA. This thesis tries to explain why. Social Revolution Theory and Social Movement Theory provide explanations based on issues of “poverty”, disregarding the specific characteristics of the guerrilla groups and their supporters, as well as the influence of specific persuasive processes between the leaders of the groups and their followers. Integrative complexity theory, on the contrary, provides a consistent method to analyze cognitive processes: because people tend to reject complex and sophisticated explanations that require mental efforts, simplicity was the key for success. To prove which guerrilla group provided a simpler worldview, a sample of official documents of SP and MRTA are compared. Finally, content analysis is applied through the Paragraph Completion Test (P.C.T.). ^

Dynamic data retrieval on the World Wide Web

Methods for accessing data on the Web have been the focus of active research over the past few years. In this thesis we propose a method for representing Web sites as data sources. We designed a Data Extractor data retrieval solution that allows us to define queries to Web sites and process resulting data sets. Data Extractor is being integrated into the MSemODB heterogeneous database management system. With its help database queries can be distributed over both local and Web data sources within MSemODB framework. ^ Data Extractor treats Web sites as data sources, controlling query execution and data retrieval. It works as an intermediary between the applications and the sites. Data Extractor utilizes a twofold “custom wrapper” approach for information retrieval. Wrappers for the majority of sites are easily built using a powerful and expressive scripting language, while complex cases are processed using Java-based wrappers that utilize specially designed library of data retrieval, parsing and Web access routines. In addition to wrapper development we thoroughly investigate issues associated with Web site selection, analysis and processing. ^ Data Extractor is designed to act as a data retrieval server, as well as an embedded data retrieval solution. We also use it to create mobile agents that are shipped over the Internet to the client's computer to perform data retrieval on behalf of the user. This approach allows Data Extractor to distribute and scale well. ^ This study confirms feasibility of building custom wrappers for Web sites. This approach provides accuracy of data retrieval, and power and flexibility in handling of complex cases. ^

Schools and the formation of Black identity during the Civil Rights Movement: Change and resistance in Holly Springs, Mississippi, 1964--1974

Desegregation of social and public spaces was the most visible result of the Civil Rights Movement. After 1960, the integration of schools in Mississippi became a source of conflict. The social change of Civil Rights attacked the social order of White Resistance that supported the state superstructure. The public schools were a place for the discovery of identity for Blacks. The integrated on of the schools caused many Whites to leave rather than be integrated with Blacks. Desegregation of schools was also a slow process because the local and state government could not enforce the decisions of the US Courts, leading Blacks to realize their place in American society could only be secured through individual action. ^ This work explains the role of schooling during the integration of the Holly Springs Separate School System. The process of forging a new identity by local Blacks is examined against the forces of social change and resistance. I addition, this work examines the perils for the Blacks as they faced the uncertainty of change in the crucial Civil Rights years between 1964 and 1974. ^ This work analyzes how the Black community dealt with the problems triggered by the desegregation of the school system in Holly Springs, of a constructed social condition, a psychological state of being, the realities of racism and segregation, and the change and resistance between the individual and the collective. It is based on six months of field work investigation. Although the schools were a crucial aspect of community life for Blacks and Whites, Blacks did form their identity in them. Other institutions, such churches were more crucial. Second, the aspect of politeness and belief in law made the experience in Holly Springs unique to that place, and thus, warrants further study to determine its place within the Civil Rights Movement. Finally, while the political and economic control of Holly Springs remained with Whites, desegregation led to the resegregation of the public schools: as Whites left to private schools. ^

Parental behaviors in child anxiety: An observational study

The increasing awareness of the prevalence, impairment, and long-term consequences of childhood anxiety disorders have led investigators to explore psychosocial factors in the etiology of these disorders. Recent investigations have begun to focus on family-level processes in the etiology and/or maintenance of childhood anxiety disorders, specifically patterns of parent-child interaction. The present study compared parent-child interactions across three problem-solving tasks of clinically anxious children and their mothers versus non-referred children and their mothers in terms of (1) direct observation measures, (2) children's, mothers', and independent observer's subjective ratings, (3) and children's evaluations using videotape-aided thought reconstruction. ^ Results suggested that the mothers of clinically anxious children engaged in fewer positive and more negative parenting strategies as compared to the mothers of non-referred children across three tasks. Although not significant, trends were evident among the subjective ratings reported by the clinically anxious children, mothers, and observer for the global perception indices. When videotape-aided thought reconstruction was used as a cue to elicit children's perceptions of the parent-child interactions, clinically anxious children reported less mother-referent positive statements and more mother-referent negative statements than non-referred children. ^

Horizontal genetic transfer in asexual fungi

Four aspects of horizontal genetic transfer during heterokaryon formation were examined in the asexual pathogen Fusarium oxysporum f.sp. cubense (Foc): (1) variability based on method of heterokaryon formation; (2) differences in nuclear and mitochondrial inheritance; (3) the occurrence of recombination without nuclear fusion; (4) the occurrence of horizontal genetic transfer between distantly related isolates. The use of non-pathogenic strains of Fusarium oxysporum as biocontrol agents warrants a closer examination at the reproductive life cycle of this fungus, particularly if drug resistance or pathogenicity genes can be transmitted horizontally. Experiments were divided into three phases. Phase I looked at heterokaryon formation by hyphal anastomosis and protoplast fusion. Phase II was a time course of heterokaryon formation to look at patterns of nuclear and mitochondrial inheritance. Phase III examined the genetic relatedness of the different vegetative compatibility groups using a multilocus analysis approach. Heterokaryon formation was evident within and between vegetative compatibility groups. Observation of non-parental genotypes after heterokaryon formation confirmed that, although a rare event, horizontal genetic transfer occurred during heterokaryon formation. Uniparental mitochondria inheritance was observed in heterokaryons formed either by hyphal anastomosis or protoplast fusion. Drug resistance was expressed during heterokaryon formation, even across greater genetic distances than those distances imposed by vegetative compatibility. Phylogenies inferred from different molecular markers were incongruent at a significant level, challenging the clonal origins of Foc. Mating type genes were identified in this asexual pathogen Polymorphisms were detected within a Vegetative Compatibility Group (VCG) suggesting non-clonal inheritance and/or sexual recombination in Foc. This research was funded in part by a NIH-NIGMS (National Institutes of Health-National Institute of General Medical Sciences) Grant through the MBRS (Minority Biomedical Research Support), the Department of Biological Sciences and the Tropical Biology Program at FIU. ^

Phosphorus enrichment effects on interactions among the ecosystem components in a long-hydroperiod oligotrophic marsh in Everglades National Park

Hydrology and a history of oligotrophy unite the massive landscape comprising freshwater marsh in Everglades National Park. With restoration of water flow to the Everglades, phosphorus (P) enrichment, both from agricultural and domestic sources, may increase nutrient load to the marsh ecosystem. Previous research of P enrichment of Everglades soil, periphyton, and macrophytes revealed each of these ecosystem components responds to increased P loads with increased production and nutrient content. Interactions among these ecosystem components and how P affects the magnitude and direction of interaction are poorly understood and are the focus of my research. Here I present results of a two-year, two-factor experiment of P enrichment and manipulation in Everglades National Park. I quantified biomass, nutrient content, and production for periphyton and macrophyes and found macrophyte removal drives change in nutrient content, biomass, and production of periphyton. Periphyton removal did not appear to control macrophyte dynamics. Soil chemical and physical characteristics were explained primarily by site differences but there was an enrichment effect of soil porewater nitrite + nitrate, nitrite, and soluble reactive phosphorus. Flocculent materials production and depth were significantly affected by macrophyte removal where depth and production were significantly greater with the no macrophyte treatment. The dominant macrophyte of the marsh, Eleocharis cellulosa, increased more in the unenriched marsh than in the enriched marsh. The combination of these findings suggests that dynamics in floc and periphyton are controlled primarily by the presence of periphyton and that this relationship is significantly affected by low-level P enrichment. These results may be valuable in their application to both managers and policy makers who are involved in the Everglades restoration process. ^
