The present  research studies Satisfaction  with  Life and Future Time Perspective, in itsdifferent dimensions (goals, temporal location of goals and temporal altitudes), from adolescence to elder ages. This study evaluated 570 males and females between 16 and 65 years old, from two different socioeconomic levels in Lima, Peru, through a non­ experimental, evolutionary transversal design. Tools used in this research were the Motivational Induction Method (MIM) and the Temporal Altitudes Scale (TAS) by Nultin (1985), and the Satisfaction with Life Scale (SWLS) by Pavot & Diener (1993). Results show that there are significan! differences on the construction and temporal Iocation of goals, altitudes towards present, past and future and in the levels of Life Satisfaction due to the variable age. lt was also found that socioeconomic leve! influences these processes more than gender. / Este estudio aborda los constructos de Perspectiva Temporal Futura, en sus diferentes dimensiones (Metas, ubicación temporal de las metas y Actitudes Temporales) y de Satisfacción con la vida, desde la adolescencia en adelante. A través de un diseño no experimental, evolutivo transversal, se evaluó a 570 personas de ambos sexos entre los 16 y los 65 años, de dos niveles socioeconómicos de Lima, Perú. Los instrumentos utilizados fueron el Método de Inducción Motivacional (MIM), la Escala de Actitudes Temporales (TAS) de Nuttin (1985) y la Escala de Satisfacción con la Vida (SWLS) de Pavot y Diener  (1993). Los resultados muestran que la edad supone diferencias importantes en la construcción de las metas y su ubicación temporal, así como en las actitudes hacia el presente, pasado y futuro y en los ni veles de satisfacción. Asimismo, evidencia que el nivel socioeconómico, más que el sexo, influye en estos procesos.

Doenças e comportamentos de risco relacionados ao polimorfismo T102C do gene 5- HT2A, como esquizofrenia, suicídio, impulsividade, alcoolismo, tabagismo, entre outros, podem encurtar o tempo de vida médio. Uma amostra de 687 indivíduos residentes na região metropolitana da Grande Porto Alegre foi genotipada e categorizada de acordo com suas respectivas idades e gêneros. Foram observadas diferenças significativas entre a distribuição dos genótipos do polimorfismo T102C do gene 5-HT2A e idade média da amostra (p=0,026) e também entre os genótipos e grupos etários (p=0,012). Estes resultados sugerem que o polimorfismo T102C do gene 5-HT2A possa desempenhar algum papel no tempo de vida médio dos seres humanos. / Diseases and risk behaviors related to the T102C polymorphism of the 5-HT2A gene such as schizophrenia, suicide, impulsivity, alcoholism, smoking addiction, among others, may potentially shorten mean life span.

Scholars have studied the network's public affairs content and unedited "gavel-to-gavel" style of production that distinguish it from other television channels. However, the network's ownership structure and funding, which are also unique, have not been systematically analyzed. This study fills a gap in C-SPAN scholarship by providing a structural analysis of the network. C-SPAN was founded and is sponsored by the U.S. cable industry. The industry insists its support for the network is based on public service. However, this study reveals that C-SPAN affords the cable industry a number of substantial political economic benefits: a political lever in Washington and with local franchise authorities, a risk-free testing ground for new products and services, and assistance in selling subscriptions for other fee-based services. This study argues that these material benefits are the motivation for the cable industry's support, not public service. It also is argued that C-SPAN can only be comprehensively understood through its relationship to the capitalist political economy of the U.S. To contextualize this relationship, the study provides a history of Congressional television, the cable industry, and satellite technology. These circumstances reveal that the network was less an act of individual cable executives' selfless altruism than a product of political pressures, economic realities, and technological breakthroughs. The study also discusses the implications of a private public affairs network. C-SPAN is a perfect case study of what has been labeled "neoliberalism," or the form of global capitalism based on privatizing social services and regulating industry using rules favorable to the needs of capital, not civil, society. At a social level, the network enables the accumulation of wealth for a select few, enabling these private interests to gain social power. The study concludes that C-SPAN may serve the public, but it is not a public service. / Committee in charge: Janet Wasko, Chairperson, Journalism and Communication; Carl Bybee, Member, Journalism and Communication; Gabriela Martinez, Member, Journalism and Communication; John Foster, Outside Member, Sociology

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Feed supplementation of the animals affects the pasture intake and may influence its productive and structural characteristics. Morphogenesis is a valuable tool for the dynamics understanding of the pasture, however the morphogenetic studies related to sorghum culture are still scarce as well as the evaluation of the supplementation effects on these characteristics. The objective of the present study was to evaluate the effects of the different levels of supplementation on the morphogenetic characteristics of sorghum forage (Sorghum bicolor (L.) Moench) submitted to continuous grazing of beef steers. The experiment was performed at the Beef Cattle Laboratory of UFSM from January to April, 2013. Morphogenetic measures were taken by the marked tiller technique in order to determine the morphogenetic variables of sorghum forage. The completely randomized experimental design was used, with measures repeated in time, with three treatments and two repetitions (area) for the morphogenetic characteristics. The results of the morphogenetic variables were submitted to variance analysis with 5% of significance level using PROC MIXED. The analyses were performed with the assistance of the statistical package SAS 9.1.3 (2009). By increasing the supplementation level offered to the animals it was observed a lower value for the Number of Live Leafs (2.77, 3.34 and 3.55) and Leaf Elongation Rate (0.06, 0.09 and 0.08) characteristics. The variables Leaf Appearance Rate (0.0041, 0.0043 and 0.039), Leaf Senescence Rate (0.05, 0.06 and 0.11) and Phyllochron (283.96, 265.21 and 278.62) were not influenced by the different supplementation levels. There was a difference among the evaluation periods for the characteristics Leaf Life Span (1081.1, 986.25 and 788.79) and Leaf Elongation Length (350.58, 312.83 and 326.36). For the characteristics Canopy Height, Pseudo Stem Length, and Final Length of Blades there was an interaction between treatment and period. / A suplementação alimentar dos animais afeta o consumo do pasto e pode influenciar suas caraterísticas produtivas e estruturais. A morfogênese é uma valiosa ferramenta para a compreensão da dinâmica do pasto, porém os estudos morfogênicos referentes à cultura do sorgo ainda são escassos, bem como a avaliação dos efeitos da suplementação sobre estas características. O objetivo do presente estudo foi avaliar os efeitos de diferentes níveis de suplementação sobre as características morfogênicas do sorgo forrageiro (Sorghum bicolor (L.) Moench) submetido ao pastejo contínuo de novilhos de corte. O experimento foi conduzido no Laboratório de Bovinocultura de Corte da UFSM no período de janeiro a abril de 2013. Foram tomadas medidas morfogênicas pela técnica de perfilhos marcados para determinação das variáveis morfogênicas do sorgo forrageiro. O delineamento experimental foi inteiramente casualizado, com medidas repetidas no tempo, com três tratamentos e duas repetições (área) para as características morfogênicas. Os resultados das variáveis morfogênicas foram submetidos à análise de variância em nível de 5% de significância, utilizando o PROC MIXED. As análises foram realizadas com auxílio do pacote estatístico SAS 9.1.3 (2009). Ao aumentar o nível de suplementação ofertado aos animais, observou-se menor valor para as características de Folhas Vivas (2,77, 3,34 e 3,55) e Taxa de Alongamento Foliar (0,06 0,09 e 0,08). Não foram influenciadas pelos diferentes níveis de suplementação as variáveis Taxa de Aparecimento Foliar (0,0041, 0,0043 e 0,039), Taxa de Senescência Foliar (0,05, 0,06 e 0,11), Filocrono (283,96, 265,21 e 278,62). Para as características Duração de Vida da Folha (1081,1, 986,25 e 788,79) e Duração de Elongação Foliar (350,58, 312,83 e 326,36) houve diferença entre os períodos de avaliação. Para as características Altura de Dossel, Comprimento de Pseudocolmo e Comprimento Final de Laminas houve interação entre tratamento e período.

: Midlife Crisis is a very popular concept describing middle adulthood. Faced with imminent death, people stop on the way to achieve their goals, to review their achievements and to assess what you already have and what you still want to achieve to fulfill their dreams. The theoretical part deals mainly with the definition of middle adulthood, midlife crisis, life satisfaction and personal well-being and also presents an overview of basic theories and research on these topics. Empirical part is focused on finding how this concept is understood and whether their own lives and the lives of their loved ones this stage recognize as life stage specific symptoms within the definition of midlife crisis and how this developmental stage experience. The work also deals with the psychological differences in experiencing developmental stages middle-aged men and women and ways of coping. Key words: middle age, crisis, adulthood, life span development, individuation, life review

Performance on the Spatial Span subtest of the Wechsler Memory Scale has been viewed as an indicator of working memory and visuospatial processing. A number of factors including age and gender have been posited to effect performance on Spatial Span by older adults. The current study examined the impact of various forms of cognitive impairment and severity of impairment on Spatial Span performance. Five hundred thirty-eight individuals between the ages of 65 and 89 were evaluated in a university memory disorders clinic using a battery of neuropsychological tests that included Spatial Span. Participants were grouped by consensus diagnosis into type of cognitive impairment (Alzheimer's disease, vascular disease, amnestic mild cognitive impairment or non-amnestic mild cognitive impairment) or cognitively normal. As expected, an increase in severity of impairment results in a decrease in Spatial Span Total Score. Other findings included a weak relationship between age and Spatial Span Total Score. Gender, as well as age, did not fully account for the decline in Spatial Span Total Score. Spatial Span Forward score was not as good a predictor of severity in that reduction in score for Spatial Span Forward remains relatively stable regardless of level of impairment. Spatial Span Backward performance was found to be more sensitive to severity. No significant differences were found between performance of Alzheimer's disease and vascular disease suggesting they share similar deficit patterns with regard to the cognitive abilities measured by the Spatial Span subtest. A comparison between those diagnosed with mild cognitive impairment and individuals without such a diagnosis showed no significant difference suggesting that visuospatial processes are not affected early in the dementing process.

This dissertation is focused on the study of selected additives and their effect on positive and negative electrodes of Ni-Zn secondary cells. The first group of additives consists of the inorganic compounds that reduce zinc oxide solubility and thus prevents shape changes of the zinc electrode. The second group contains organic additives that have the beneficial effect of dendrite growth prevention. All additives were examined in relationship to their compatibility with the positive electrode and to their effect on the zinc electrode dendrites inhibition, hydrogen evolution and corrosion inhibition. Moreover, the study of decomposition kinetics of supersaturated zincate solution with the first group of additives was performed. Finally, a short study of pulse regime charging mode with regard to dendrites inhibition was performed and evaluated.
