Nous avons cherché des relations empiriques entre l’abondance des macrophytes submergés et le développement résidentiel du bassin versant, les propriétés du lac et la présence de milieux humides dans 34 lacs de la région des Laurentides et de Lanaudière sélectionnés à travers un gradient de développement résidentiel. Les macrophytes submergés ont été échantillonnés par méthode d’échosondage à l’intérieur de la zone littorale. L’abondance moyenne des macrophytes a ensuite été estimée à l’intérieur de quatre zones de croissance optiquement définies (profondeur maximale = 75 %, 100 %, 125 % et 150 % de la profondeur de Secchi) ainsi qu’à l’intérieur de toute la zone littorale. L’occupation humaine a été considérée selon trois échelles spatiales : celle présente 1- dans un rayon de 100 mètres autour du lac, 2- dans la fraction du bassin versant qui draine directement vers le lac et 3- dans le bassin versant en entier. Nous avons aussi testé, lac par lac, l’effet de la pente locale sur l’abondance des macrophytes. Nous avons observé des corrélations positives et significatives entre l’abondance des macrophytes submergés et l’occupation humaine de l’aire de drainage direct (r > 0.51). Toutefois, il n’y a pas de relation entre l’abondance des macrophytes submergés et l’occupation humaine de la bande de 100 mètres entourant le lac et du bassin versant entier. Les analyses de régression multiple suggèrent que l’abondance des macrophytes submergés est faiblement corrélée avec l’aire du lac (+) et avec la présence de milieux humides dans le bassin versant entier (-). Localement, l’abondance des macrophytes est reliée à la pente et à la profondeur qui expliquent 21% de la variance. Les profondeurs de colonisation maximale et optimale des macrophytes submergés sont corrélées positivement au temps de résidence et à la profondeur de Secchi et négativement à l’occupation humaine et à l’importance des milieux humides. / We searched for empirical relationships between whole-lake submerged macrophyte abundance and residential development, lake properties and wetlands in 34 lakes from the Laurentides-Lanaudière region subjected to a wide range of residential development. Submerged macrophyte abundance was assessed by echosounding of the entire littoral zone. Human encroachment was measured at three spatial scales: Within 1- a 100 m-wide buffer strip circling the lake, 2- the fraction of the watershed that drains directly into the lake and 3- the entire watershed. Single and multiple regression were used to test the effect of residential development on macrophyte abundance in the entire littoral zone and within four optical growth zones defined by Secchi depth. The local effect of slope on local macrophyte abundance was also tested in individual lakes. We found significant positive correlations between submerged macrophyte abundance and dwelling density present within the direct drainage area (r > 0.51). In contrast, there was no significant relation between macrophyte abundance and human occupation of the 100 m-wide buffer circling lake and the entire watersheds. Multiple regression analysis suggest that submerged macrophyte abundance is weakly correlated with lake area (+) and wetland importance within the entire watershed (-). Locally, macrophyte abundance is related to slope and depth which explained together 21% of the variance. Maximum and optimum colonization depths of submerged macrophytes were positively correlated to residence time and Secchi depth and negatively to human occupation and to wetland importance.

In this context the Vaca Brava Stream is patially inserted in the Vaca Brava Municipal Park (VBMP), which possess na important environmental role. This study reports na evaluation of the physical, chemical and microbiological characteristics of the Vaca Brava Stream, with a temporal and spatial analyses of its limnological characteristics. The samples collecting was carried out in eight points along the longitudinal axis of the Vaca Brava Stream between June 2015 and May 2016, encompassing the rainy and dry seasons. Twenty-seven physical-chemical and biological parameters were monitored being that, in the field the values of eight were obtained with the remaining 19 measured in a laboratory. For the results a principal component analysis (PCA) was performed, with the t-test to verify differences between the collecting periods (dry and rainy). In a general manner, the results indicated waters with low values of turbidity, nutrients, DBO5 and Chlorophyll-a. However, there were exceptions, as the high concentrations of total phosphor, orthophosphate, total nitrogen (Kjeldahl), and amoniacal nitrogen, recorded in some places during the dry season. Low concentrations of dissolved oxygen were also frequente in the study area. The results point to na expected seasonality which may be related to a larger contribution of poluting sources. The protection of the Vaca Brava Stream headwaters contribute to better values in the sampling points located upstream, most probably owing to the fact of the VBMP. The disordely human occupation is reflected in the higher housing concentration (especially vertical) in the intermediar parts of the Vaca Brava Stream, being coherent with the more negative results expressed in this stretch of the stream. Among all sampling points, the most relevant for the majority of alterations is the Point 5, which might be reflecting the efluente loads coming from sewers, commerce, and small industries as channeled form or surface runoff in the rainy seasoin. / O processo de ocupação do solo em Goiânia demostra que, devido ao seu acelerado crescimento populacional, a cidade reproduziu todas as contradições socioambientais de uma grande metrópole. Neste contexto, o córrego Vaca Brava está parcialmente inserido no Parque Municipal Vaca Brava (PMVB), que possui um papel importante ambientalmente. Esse estudo relata uma avaliação das características físicas, químicas e microbiológicas do córrego Vaca Brava, com uma análise da variação temporal e espacial das suas características limnológicas. A coleta das amostras foi realizada em oito pontos no eixo longitudinal do córrego Vaca Brava, entre junho de 2015 e maio de 2016, abrangendo as estações de chuva e seca. Foram monitorados 27 parâmetros físico-químicos e biológicos, sendo que, em campo, foram obtidos os valores de oito parâmetros, com os demais 19 medidos em laboratório. Para os resultados foi realizada uma análise de componentes principais (PCA), com o teste t para verificar a existência de diferença entre os períodos de coleta (seca e chuva). De maneira geral, os resultados indicaram águas com baixos valores de turbidez, nutrientes, DBO5 e Clorofila-a. No entanto, ocorreram exceções, como as elevadas concentrações de fósforo total, ortofosfato, nitrogênio total (Kjeldahl) e nitrogênio amoniacal registradas em alguns locais no período de seca. Baixas concentrações de oxigênio dissolvido também foram frequentes na área de estudo. Os resultados apontam para uma sazonalidade esperada, que podem estar correlacionados a uma maior contribuição de fontes poluentes. A proteção das cabeceiras do córrego Vaca Brava contribui para valores amenos nos pontos amostrais mais à jusante, muito provavelmente devido ao fato da criação do PMVB. A ocupação humana desordenada se reflete na maior concentração de residências (especialmente verticais) nas partes intermediárias do córrego Vaca Brava, sendo coerente com os resultados mais negativamente expressivos nesse trecho do córrego. Dentre todos os pontos amostrais, o de maior relevância para a maioria das alterações é o Ponto 5, que pode estar refletindo cargas de efluentes advindas de esgotos, comércio e pequenas indústrias, seja de forma canalizada ou por enxurradas na estação chuvosa.

Workplace discrimination for individuals with visual impairments in the U.S. is an ongoing issue dating before the founding of the EEOC and the enactment of the ADA. Despite laws enacted to protect against unequal treatment in the workplace, the EEOC continues to receive submissions of formal discrimination charges from individuals with visual impairments. The workplace is experiencing changes with increasing amounts of older adults, women, minorities, and the use of technology and the Internet. By examining characteristics of the discrimination charges and the resulting outcomes, the knowledge gained can describe the current situation and the historical progression of workplace discrimination for individuals with visual impairments. The purpose of this cross-sectional study is to understand through descriptive, non-parametric, and logistical regression analyses of secondary data, meaningful associations regarding workplace discrimination and Americans with visual impairments. Study results showed that charging party characteristics of age, gender, and race were found to be predictive of types of discrimination charges and resolutions outcomes. Respondent characteristics of employer region of location, size, and industry were also found to be predictive of types of discrimination charges and resolution outcomes. Differences were revealed between discrimination charges before and after the enactment of the ADAAA, yet not between resolution outcomes before and after the enactment of the ADAAA. Additionally, discrimination charges and resolution outcomes were determined to be associated with one another. Implications for employees, employers, and professionals who work with individuals with visual impairments are addressed and recommendations for further research are provided.

We have chosen to focus on the meaning of long-term income support dependency regarding health, goal setting and motivation for the recipient of economical aid. We have chosen to use semi structurized interviews to achieve our goal of reaching the clients experience of long-term income support dependency. The study consists of interviews of six clients whose answers have been analyzed through appliance of Kielhofner´s Model of human occupation, Scheff´s Shame in self and society.    Our results show regarding, 1) the factor health that long-term income support dependency may elevate the risk of illness and less experienced options of possibilities to act. 2) regarding the factor goal setting, that goals may be inefficiently used during social work with long-term income support dependent clients and may result in a disorganized relationship between client and social worker in the sense of making the parties pull in opposite direction. 3) regarding the factor motivation, that long-term income support dependency and the living with the emotion of shame elevates the risk of maintaining a negative image of oneself that limits the willpower to assimilate new knowledge and/or skills. This also effects the clients belief in their own capacity to change their current negative situation. Which may impact the rate of success in motivational social work and the individuals own possibilities to live an independent life, free of income support. Throughout the study we have encountered the traces of shame as a social emotion and emphasize on the environments pressure for change and socialization.

A rápida ocupação desordenada desses espaços, motivada pelo desenvolvimento econômico e potencializada por diferentes atividades turísticas, nessas últimas cinco décadas, resulta no desperdício de solo e recursos, que afetam os ecossistemas da área, provocando risco às populações fixa e flutuante. A análise geoambiental compreende a área entre a Ponta de Itaipu ao Maciço de Itatins, situada na linha de costa do Estado de São Paulo, na Região Metropolitana da Baixada Santista. Voltada às unidades geomorfológicas praias, manguezais, morros e encosta, a análise fornece dados para conhecimento dos processos críticos de erosão, deslizamento e inundação existentes na área desse estudo. O levantamento desses dados auxilia a equação dos principais fatores geológicos e geomorfológicos que influenciam o controle das áreas onde ocorre a interação entre os complexos ecossistemas urbanos e os ecossistemas costeiros em equilíbrio dinâmico. O estudo compreende diferentes fases: reconstrução histórica da colonização, emancipação dos municípios que integram a área de estudo, análise das características de ocupação, bem como a comparação de fotografias aéreas (1962 com 2002) e trabalho de campo. Assim, foram identificados dezesseis pontos de áreas críticas, constatando-se que processos críticos têm origem no uso indevido do solo, principalmente no desmatamento. Para a racionalização do uso do solo e recursos, que preservam os ecossistemas, minimizam e até evitam risco à população, propõe-se que seja trabalhada a cultura de segurança, indicada no Planejamento Ambiental dos programas direcionados ao Desenvolvimento Sustentável, contida na Agenda 21, que trata da Promoção do Desenvolvimento Sustentável... / The space occupation in coastal regions is always a difficult problem to be solved due to the environmental complexity of these areas. The rapid and disorganized occupation in the studied area is due to the economic development and by tourist activities in these last fifty decades. These combined actions had a direct impact into soil waste and other resources that affect the whole area ecosystems leading to risks to the fixed and seasoning population. A geoenvironment analysis was carried on in the coastal line of the São Paulo State between the Ponta de Itaipu and Maciço de Itatins located in the Região Metropolitana of the Baixada Santista. This analysis had been concentrated in the geomorphological units of beaches, mangroves and topographic elevated terrains within, this area, and its results leads to better understanding of the critical processes of erosion, floods and landslides presently in action. The resulting data also allows to the better knowledge of main geologic and geomorphologic factors equation that affects these areas where we have the interaction of complex urban ecosystems and coastal ecosystems of dynamic equilibrium. The historical reconstruction from the beginning of the colonial time to the present days with the analysis of the specific characteristics of the different types of occupation, the comparison of air photos dated from 1962 to those of 2002 and field work, allowed to the identification of sixteen critical points in this area. The critical processes is mainly a result of the undue soil management specially its deforestation. It is here proposed to these areas the use of the principle of safety culture as indicated by the Environmental Planning as mentioned in the Sustentation Development Program inside of the Agenda 21 that deals with the promotion of the sustainable development of the humans enrolments...
