Historia de la natación en la ciudad de La Plata

El presente texto hace referencia a mis estudios de tesina de grado los cuales me encuentro realizando para la Licenciatura Universitaria en Educación Física (LUEF) en el Departamento de Educación Física de la Facultad de Humanidades y Ciencias de la Educación (FaHCE) de la Universidad Nacional de La Plata (UNLP). Mientras transcurría el período de cursadas en el Profesorado Universitario en Educación Física (PUEF), más específicamente desde el ingreso a la carrera, he observado el problema de que los alumnos que cursan los ejes Natación 1 y 2 en las asignaturas Educación Física 2 y 3 en el segundo y tercer año del plan de estudios vigente (2000) comparado con otro plan mas antiguo (1984), gran número de cursantes desaprueban las comisiones existentes; entonces es que me pregunté: ¿cuál es el problema por el que tantos alumnos desaprueban estos ejes? En base a eso he decidido investigar sobre dicho tema, para conocer si el problema son los alumnos, los docentes, los contenidos, la teoría-práctica, los métodos de enseñanza, los saberes previos, la evaluación, etc. , es decir, los aspectos pedagógicos y didácticos en general. En función de lo desarrollado anteriormente considero que en mi tesis de grado, no podía faltar un capítulo de la historia de la Natación en la Ciudad de La Plata. Dicho capítulo es el primero de la tesina, en el cual describo en un recorrido socio-histórico la creación de la ciudad de La Plata, detallo cómo y por qué han surgido los primeros clubes deportivos con sus respectivos natatorios en la ciudad. Particularizo sobre la creación de la UNLP y cómo ha llegado el PUEF a incorporarse en la FaHCE. Y por último, relato la incorporación del el eje Natación en el plan de estudios como así mismo en las asignaturas Educación Física 2 y 3. Describir el contexto socio- histórico cultural es importante para poder comprender el motivo y las circunstancias de la incorporación de la natación en el PUEF. Metodológicamente me inclinaré por una investigación cualitativa y cuantitativa donde la recolección de datos será realizada por medio de encuestas, entrevistas y observaciones de campo. Así mismo, otro tipo de fuentes como planes de estudio, leyes o legislación, material bibliográfico, serán analizados. Para finalizar, intentaré triangular los datos relevados en el trabajo de campo con el objeto de arribar a conclusiones posibles y dar respuesta a mi interrogante

Job uncertainty and personal control during downsizing: A comparison of survivors and victims

This study developed and tested a model of job uncertainty for survivors and victims of downsizing. Data were collected from three samples of employees in a public hospital, each representing three phases of the downsizing process: immediately before the announcement of the redeployment of staff, during the implementation of the downsizing, and towards the end of the official change programme. As predicted, levels of job uncertainty and personal control had a direct relationship with emotional exhaustion and job satisfaction, In addition, there was evidence to suggest that personal control mediated the relationship between job uncertainty and employee adjustment, a pattern of results that varied across each of the three phases of the change event. From the perspective of the organization's overall climate, it was found that levels of job uncertainty, personal control and job satisfaction improved and/or stabilized over the downsizing process. During the implementation phase, survivors experienced higher levels of personal control than victims, but both groups of employees reported similar levels of job uncertainty. We discuss the implications of our results for strategically managing uncertainty during and after organizational change.

COMUNICAÇÃO E COMPARTILHAMENTO DE CONTEÚDO: O USO DE RECURSOS EDUCACIONAIS ABERTOS POR DOCENTES DA UMESP

No âmbito do Direito à Comunicação, dos Direitos Humanos e da discussão a respeito dos Direitos Autorais sobre obras principalmente literárias e científicas, este trabalho tem como principal objetivo o desenvolvimento e aplicação de uma pesquisa de campo de caráter exploratório. Ele busca estabelecer um mapeamento do uso das práticas de produção e compartilhamento de conteúdo aberto por parte do corpo docente da UMESP, por meio do uso de licenciamento livre do tipo Commons e seguindo os preceitos apregoados pelo movimento dos Recursos Educacionais Abertos (REA). Portanto, o método estatístico utilizado foi o de amostragem probabilística aleatória simples utilizando-se de questionário com perguntas fechadas, possibilitando a elaboração de uma base de dados consistente que foi explorada no intuito de confirmar a hipótese inicialmente formulada, além de contemplar outras inferências não menos interessantes. A principal conclusão apresentada é que, mesmo que não seja de conhecimento da maioria do corpo docente da UMESP sobre o compartilhamento de conteúdo sob licenciamento livre e nem tampouco sobre o movimento REA, não existem restrições significativas quanto à adesão a tais práticas.

A INCLUSÃO SOCIAL E AS MEDIAÇÕES NA RECEPÇÃO DA COMUNICAÇÃO MERCADOLÓGICA TELEVISIVA POR PESSOAS COM DEFICIÊNCIA VISUAL

Este trabalho é estimulado pela reflexão sobre a recepção da comunicação mercadológica televisiva por pessoas com deficiência visual, assim como sobre a percepção quanto às iniciativas do governo e das empresas em prol da inclusão. O estudo busca, com base na Teoria das Mediações, que é estudada por teóricos dos Estudos de Recepção, entender de que forma as pessoas com deficiência visual interagem com as diferentes categorias de comerciais de televisão, a partir de seus valores, percepções de mundo e condições em que se encontram. Deste modo, observa-se ainda o nível de sentimento de pertencimento das pessoas com deficiência visual quanto à preocupação do governo e das empresas em causas sociais. Os procedimentos que dirigem a investigação caracterizam-se por uma reflexão a partir de dados decorrentes de pesquisa bibliográfica, articulada a uma pesquisa de campo de natureza qualitativa. O trabalho conclui que a percepção das pessoas com deficiência visual se distancia do que está sendo proposto, feito e aparentemente sendo bem divulgado em prol da inclusão; bem como, observa a necessidade de aprimoramento da conscientização da sociedade, e consequentemente dos comunicadores, sobre a importância da aproximação entre as pessoas com deficiência visual e a comunicação mercadológica televisiva. Nesta percepção, o trabalho apresenta sugestões no âmbito comunicacional que poderiam tornar as causas sociais realmente expressivas na vida das pessoas com deficiência visual.

Challenges for expatriate managers:an exploration of cross-cultural management, adjustment, and training issues faced by Anglo-American managers in Hong Kong

This field work study furthers understanding about expatriate management, in particular, the nature of cross-cultural management in Hong Kong involving Anglo-American expatriate and Chinese host national managers, the important features of adjustment for expatriates living and working there, and the type of training which will assist them to adjust and to work successfully in this Asian environment. Qualitative and quantitative data on each issue was gathered during in-depth interviews in Hong Kong, using structured interview schedules, with 39 expatriate and 31 host national managers drawn from a cross-section of functional areas and organizations. Despite the adoption of Western technology and the influence of Western business practices, micro-level management in Hong Kong retains a cultural specificity which is consistent with the norms and values of Chinese culture. There are differences in how expatriates and host nationals define their social roles, and Hong Kong's recent colonial history appears to influence cross-cultural interpersonal interactions. The inability of the spouse and/or family to adapt to Hong Kong is identified as a major reason for expatriate assignments to fail, though the causes have less to do with living away from family and friends, than with Hong Kong's highly urbanized environment and the heavy demands of work. Culture shock is not identified as a major problem, but in Hong Kong micro-level social factors require greater adjustment than macro-level societal factors. The adjustment of expatriate managers is facilitated by a strong orientation towards career development and hard work, possession of technical/professional expertise, and a willingness to engage in a process of continuous 'active learning' with respect to the host national society and culture. A four-part model of manager training suitable for Hong Kong is derived from the study data. It consists of a pre-departure briefing, post-arrival cross-cultural training, language training in basic Cantonese and in how to communicate more effectively in English with non-native speakers, and the assignment of a mentor to newly arrived expatriate managers.

Ecological studies on:(a) the use of colonisation samplers in relation to biological surveillance of river water quality (b) the requirements of freshwater gastropoda

Some of the factors affecting colonisation of a colonisation sampler, the Standard Aufwuchs Unit (S. Auf. U.) were investigated, namely immersion period, whether anchored on the bottom or suspended, and the influence of riffles. It was concluded that a four-week immersion period was best. S. Auf. U. anchored on the bottom collected both more taxa and individuals than suspended ones. Fewer taxa but more individuals colonised S. Auf. U. in the potamon zone compared to the rhithron zone with a consequent reduction in the values of pollution indexes and diversity. It was concluded that a completely different scoring system was necessary for lowland rivers. Macroinvertebrates colonising S. Auf. U. in simulated streams, lowland rivers and the R. Churnet reflected water quality. A variety of pollution and diversity indexes were applied to results from lowland river sites. Instead of these, it was recommended that an abbreviated species - relative abundance list be used to summarise biological data for use in lowland river surveillance. An intensive study of gastropod populations was made in simulated streams. Lynnaea peregra increased in abundance whereas Potamopyrgas jenkinsi decreased with increasing sewage effluent concentration. No clear-cut differences in reproduction were observed. The presence/absence of eight gastropod taxa was compared with concentrations of various pollutants in lowland rivers. On the basis of all field work it appeared that ammonia, nitrite, copper and zinc were the toxicants most likely to be detrimental to gastropods and that P. jenkinsi and Theodoxus fluviatilis were the least tolerant taxa. 96h acute toxicity tests of P. jenkinsi using ammonia and copper were carried out in a flow-through system after a variety of static range finding tests. P. jenkinsi was intolerant to both toxicants compared to reports on other taxa and the results suggested that these toxicants would affect distribution of this species in the field.

Marketing strategy and new product development in the UK credit card industry

The development of new products in today's marketing environment is generally accepted as a requirement for the continual growth and prosperity of organisations. The literature is consequently rich with information on the development of various aspects of good products. In the case of service industries, it can be argued that new service product development is of as least equal importance as it is to organisations that produce tangible goods products. Unlike the new goods product literature, the literature on service marketing practices, and in particular, new service product development, is relatively sparse. The main purpose of this thesis is to examine a number of aspects of new service product development practice with respect to financial services and specifically, credit card financial services. The empirical investigation utilises both a case study and a survey approach, to examine aspects of new service product development industry practice relating specifically to gaps and deficiencies in the literature with respect to the financial service industry. The findings of the empirical work are subsequently examined in the context in which they provide guidance and support for a new normative new service product development model. The study examines the UK credit card financial service product sector as an industry case study and perspective. The findings of the field work reveal that the new service product development process is still evolving, and that in the case of credit card financial services can be seen as a well-structured and well-documented process. New product development can also be seen as an incremental, complex, interactive and continuous process which has been applied in a variety of ways. A number of inferences are subsequently presented.

Primary health care management in Nigeria

This research sets out to assess if the PHC system in rural Nigeria is effective by testing the research hypothesis: `PHC can be effective if and only if the Health Care Delivery System matches the attitudes and expectations of the Community'. The field surveys to accomplish this task were carried out in IBO, YORUBA, and HAUSA rural communities. A variety of techniques have been used as Research Methodology and these include questionnaires, interviews and personal observations of events in the rural community. This thesis embraces three main parts. Part I traces the socio-cultural aspects of PHC in rural Nigeria, describes PHC management activities in Nigeria and the practical problems inherent in the system. Part II describes various theoretical and practical research techniques used for the study and concentrates on the field work programme, data analysis and the research hypothesis-testing. Part III focusses on general strategies to improve PHC system in Nigeria to make it more effective. The research contributions to knowledge and the summary of main conclusions of the study are highlighted in this part also. Based on testing and exploring the research hypothesis as stated above, some conclusions have been arrived at, which suggested that PHC in rural Nigeria is ineffective as revealed in people's low opinions of the system and dissatisfaction with PHC services. Many people had expressed the view that they could not obtain health care services in time, at a cost they could afford and in a manner acceptable to them. Following the conclusions, some alternative ways to implement PHC programmes in rural Nigeria have been put forward to improve and make the Nigerian PHC system more effective.

Pathways utilized by heavy metal pollutants in urban stormwater runoff

The research concerned the assessment of the pathways utilized by heavy metal pollutants in urban stormwater runoff. A separately sewered urban residential catchment of approximately 107 hectares in Chelmsley Wood, north-east Birmingham was the subject of the field investigation. The catchment area, almost entirely residential, had no immediate industrial heavy metal input, however, industry was situated to the north of the catchment. The perimeter of the catchment was bounded by the M6 motorway on the northern and eastern sides and was believed to contribute to aerial deposition. Metal inputs to the ground surface were assumed to be confined to normal suburban activities, namely, aerial deposition, vehicular activity and anthropological activities. A programme of field work was undertaken over a 12 month period, from July 1983 to July 1984. Monthly deposition rates were monitored using a network of deposit cannisters and roadside sediment and soil samples were taken. Stormwater samples were obtained for 19 separate events. All samples were analysed for iron, lead, zinc, copper, chromium, nickel and cadmium content. Rainfall was recorded on site with additional meteorological data obtained from local Meteorological Offices. Use was made of a simple conceptual model designed for the catchment to substantiate hypotheses derived from site investigations and literature, to investigate the pathways utilized for the transportation of heavy metals throughout the catchment.

Assessment of the impact of discharges from surface water sewers on receiving water quality

A broad based approach has been used to assess the impact of discharges to rivers from surface water sewers, with the primary objective of determining whether such discharges have a measurable impact on water quality. Three parameters, each reflecting the effects of intermittent pollution, were included in a field work programme of biological and chemical sampling and analysis which covered 47 sewer outfall sites. These parameters were the numbers and types of benthic macroinvertebrates upstream and downstream of the outfalls, the concentrations of metals in sediments, and the concentrations of metals in algae upstream and downstream of the outfalls. Information on the sewered catchments was collected from Local Authorities and by observation of the time of sampling, and includes catchment areas, land uses, evidence of connection to the foul system, and receiving water quality classification. The methods used for site selection, sampling, laboratory analysis and data analysis are fully described, and the survey results presented. Statistical and graphical analysis of the biological data, with the aid of BMWP scores, showed that there was a small but persistent fall in water quality downstream of the studied outfalls. Further analysis including the catchment information indicated that initial water quality, sewered catchment size, receiving stream size, and catchment land use were important factors in determining the impact. Finally, the survey results were used to produce guidelines for the estimation of surface water sewer discharge impacts from knowledge of the catchment characteristics, so that planning authorities can consider water quality when new drainage systems are designed.

The West Midlands road transport industry

The object of this project was to identify those elements of management practice which characterised firms in the West Midlands Road Transport Industry. The object being to establish the contents of what might be termed a management policy portfolio for growth. The First Phase was the review of those factors which were generally accepted as having an influence on the success rate of transport firms in order to ascertain if they explained observed patterns. Secondly, if this were not the case, to instigate a field work study to isolate those policies which were associated with growth organizations. Investigation of the vehicle movements for the entire West Midlands Fleet over a complete licence cycle suggested that conventional explanations could not fully account for the observed patterns. To carry out the second phase of the study a sample of growth firms were visited in order to measure their attitudes on a range of factors hypothesised to affect growth. Field data were analysed to establish management activities over a wide range of areas and the results further investigated through a Principal Components and Cluster Analysis programme. The outcome of the study indicates that some past attitudes on the skills and attitudes of transport managers may have to be re-examined. As a result, the project produced a new classification of road transport firms based not on the conventional categories of long and short haul, or the types of traffics carried, but on the marketing policies and management skills employed within the organization.

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. ^

Academic orientations of African -American adolescents in Miami-Dade County

The purpose of this research was to answer the following research questions: (a) how high-achieving African-Americans maintain a “racefull” Black identity; (b) how African-American identity affects academic orientation and achievement; (c) how the school's ethnic composition affects African-American students' identity; and (d) how family structure, specifically living in female single-parent households, affects academic orientation and achievement. ^ The data were gathered in an inner-city high school in Miami, Florida. Participants were African-American adolescents, males and females, who started their first-year of high school in the fall of 1995 until their graduation in June 1999. The number of students in the sample varied from 27 students at the beginning of the project to 24 students at the time of graduation. ^ Data were gathered through intensive ethnographic field work, which involved direct participant observation of students in natural contexts; in-depth interviewing of students, peers, teachers, and families; open-ended classroom discussions on matters about the research; and focus groups. Data on demographics, levels of self-esteem and depression, hours spent doing homework, family help with school work, aspirations, and other factors were gained through a survey. ^ African-Americans in this high school developed a racefull persona and still embraced education. They did not need to be raceless to succeed. The ethnic composition of the school where these students were a minority within a minority school resulted in their developing reactive ethnicity formation. Family structure did not affect academic orientation. What made a difference in these students lives were parental support and family ties, which affected their academic orientation. ^

Effect of Hydrologic Restoration on the Habitat of The Cape Sable Seaside Sparrow, Annual Report of 2003-2004

Following on our previous year’s work on ‘Effect of hydrologic restoration on the habitat of the Cape Sable seaside sparrow (CSSS)’, we presented first year results at the Cape Sable seaside sparrow – fire planning workshop at Everglades National Park in December 2003. Later, with almost the same set of crews as in the previous year, we started field work in the first week of January and continued till May 26, 2004. Protocols for sampling topography and vegetation in 2004 were identical to the previous year. In the early season, we completed topographic surveys along two remaining transects, B and E (~16.5 km), and vegetation surveys along three transects, D, E and F (~10.8 km), leaving only the vegetation sampling on transects B and C to be completed in 2005. During April and May, vegetation sampling was completed at 230 census sites, making the total of 409 CSSS census sites for which we have complete vegetation data. We updated data sets from both 2003 and 2004, and analyzed them together using cluster analysis, ordination, weighted-averaging regression and analysis of variance, as we had in 2003. Additionally, we used logistic regression to examine the effect of vegetation structural parameters on the recent occurrence of CSSS. We also analyzed vegetation observations recorded by the sparrow census team in 1981 and annually between 1992 and 2004 to assess historical patterns of vegetation change in CSSS habitat.

Effect of Hydrologic Restoration on the Habitat of The Cape Sable Seaside Sparrow, Annual Report of 2004-2005

The major activities in Year 3 on ‘Effect of hydrologic restoration on the habitat of the Cape Sable seaside sparrow (CSSS)’ included presentations, field work, data analysis, and report preparation. During this period, we made 4 presentations, two at the CSSS – fire planning workshops at Everglades National Park (ENP), one at the Society of Wetland Scientists’ meeting in Charleston, SC, and a fourth at the Marl Prairie/CSSS performance measure workshop at ENP. We started field work in the third week of January and continued till June 3, 2005. Early in the field season, we completed vegetation surveys along two transects, B and C (~15.1 km). During April and May, vegetation sampling was completed at 199 census sites, bringing to 608 the total number of CSSS census sites with quantitative vegetation data. We updated data sets from all three years, 2003-05, and analyzed them using cluster analysis and ordination as in previous two years. However, instead of weighted averaging, we used weighted-averaging partial least square regression (WA-PLS) model, as this method is considered an improvement over WA for inferring values of environmental variables from biological species composition. We also validated the predictive power of the WA-PLS regression model by applying it to a sub-set of 100 census sites for which hydroperiods were “known” from two sources, i.e., from elevations calculated from concurrent water depth measurements onsite and at nearby water level recorders, and from USGS digital elevation data. Additionally, we collected biomass samples at 88 census sites, and determined live and dead aboveground plant biomass. Using vegetation structure and biomass data from those sites, we developed a regression model that we used to predict aboveground biomass at all transects and census sites. Finally, biomass data was analyzed in relation to hydroperiod and fire frequency.
