Estudos de acumulações de gás raso e os efeitos destes fenômenos nas ondas sísmicas são objeto de trabalho de diversos pesquisadores em diferentes partes do planeta. As respostas das acumulações de gás nas ondas sísmicas se diferenciam pelas diversas frequências dos equipamentos sísmicos e trazem informações importantes no que concerne à formação e evolução dos ambientes em questão. O Canal da Bertioga se situa no litoral Sul do Estado de São Paulo, Brasil, e consiste em um ambiente de características estuarinas que conecta a plataforma continental, em sua desembocadura oceânica, e a Baixada Santista em sua desembocadura continental. Trata-se de um sistema de baixa hidrodinâmica, com profundidades máximas de 18m, e sofre influência de seus afluentes oriundos da serra do mar. Na presente pesquisa, foram utilizadas as fontes Pinger (24 kHz), Chirp (2 - 8 kHz) e Boomer (0,5 - 2 kHz) operando simultaneamente para o levantamento de dados geofísicos e amostragens superficiais com um amostrador de mandíbulas do tipo Van Veen. Foram também obtidos cinco testemunhos sedimentares, dos quais foram obtidos dados de taxa de sedimentação. O levantamento sísmico permitiu a identificação de diversas fácies acústicas de gás nos sedimentos assim como padrões de escape. Em função da identificação dos padrões de ocorrência destas formações de gás se pôde dividir o Canal da Bertioga em três setores: Estreito, Largo do Candinho e Canal Leste. No trecho denominado de Estreito as Coberturas acústicas foram predominantes com pouca variação de cota (± 3 m), os escapes de gás foram menos ocorrentes se comparados às outras áreas e se deu especialmente em forma de Pináculos de Turbidez. No Largo do Candinho predominaram as Sombras Negras e Coberturas Acústicas muito rasas, em torno de 1 a 2 m do substrato, com grande ocorrência de escape de gás do tipo Plumas Acústicas. Por fim, O Canal Leste apresentou as maiores variações nas cotas das Coberturas Acústicas, com ocorrências mais profundas (8 m em média) e escapes de gás em forma de Plumas Intrassedimentares. Foram definidas unidades estratigráficas deposicionais que contribuíram para a proposição de uma compartimentação do canal, em função dos padrões de ocorrência de gás. A fonte boomer permitiu identificar quatro unidades estratigráficas No Canal Leste, duas no Largo do Candinho e apenas uma no Estreito, neste último trecho a penetração do sinal foi especialmente comprometida em função da constante ocorrência das Coberturas Acústicas. Diante destas evidências pôde-se concluir que o Canal da Bertioga evoluiu como dois sistemas distintos, os quais foram separados durante as regressões marinhas e conectados novamente em trato de mar alto. A mudança brusca das cotas de ocorrência das Coberturas Acústicas entre o Canal Leste e o Largo do Candinho, além de evidências de falhamentos neotectônicos do Pleistoceno tardio sugerem que a conexão destes ambientes (Estreito + Largo do Candinho e Canal Leste) pode ter sido abrupta. / Studies of shallow gas accumulations and the effects of these components in the seismic waves are studied by several researchers in different parts of the world. The responses of the gas accumulations in the seismic waves are distinguished by different frequencies of seismic equipment and provide important information regarding the formation and evolution of the environments. The Channel of Bertioga is located on the southern coast of São Paulo, Brazil, and it\'s an environment with estuarine characteristics that connects the Sea of Bertioga to its oceanic mouth, and the city of Santos to it\'s continental mouth. This is a low hydrodynamic system with maximum depths of 18m, and is influenced by its tributaries from the Serra do Mar mountains. The present study was conducted with the sources Pinger (24kHz), Chirp (2 - 8 kHz) and Boomer (0.5 - 2 kHz) operating simultaneously for the geophysical survey data, surficial sediment sampling was made with a Van Veen grab. Five cores were also acquired, of which the sedimentation rate was obtained. The seismic survey allowed the identification of several buried gas facies and seepages. Regarding the patterns in the occurrence of gas formations the Bertioga Channel could be split into three sectors: The Narrow Sector, Candinho and Eastern Sector. In the Narrow part, the Acoustic Blankings were predominant with little variation in elevation (± 3 m), seepages occurred less compared to other areas and were mostly consisting of Turbidity Pinnacles. In the Candinho sector, Black Shadows and Acoustic Blankets about 1 to 2m of the substrate prevailed, with high occurrence of seepages in the form of Acoustic Plumes. Finally, the Eastern Sector had the highest changes in the levels of Acoustic Blankets, with the deepest occurrences (8m on average) and seepages in the form of Intrasedimentary Plumes. Some stratigraphic units were defined, which contributed to the previous division by the gas occurrences. The Booomer source allowed the identification of four Stratigraphic Units inthe Eastern Channel, two in the Candinho sector and only one Stratigraphic Unit in the Narrow Sector. In the last sector signal penetration was particularly compromised due to the constant occurrence of Acoustic Blankets. Given this evidence, it was concluded that the Bertioga Channel evolved as two distinct systems, which were separated during the marine regressions and re-connected during marine transgressions. The sudden change in the depths of occurrence in Acoustic Blankets between the Eastern Channel and Candinho, and evidence of neotectonic faulting in the Late Pleistocene suggest that the connection of these environments (Narrow Sector + Candinho and Canal East) may have been abrupt.

This research investigates generational differences in Australian workers. In particular it focuses on changing trends and influences in the workplace and how different generations view and deal with these changes. The study focuses on Baby Boomers (born 1945-1963), Generation X (born 1964-1977) and Generation Y (born 1978 - 1994) across four industry sectors: Corporate, Education, Government and Not for Profit. The Australian workforce currently consists of four generations - all having distinct characteristics, working styles, needs and expectations. These differences pose challenges and opportunities to workforce management. The first step in managing the generations and their differences is to identify where the differences lie and to understand how best to cope with and exploit these differences. This research, in taking a generational cohort perspective towards analysing the modern workplace, seeks to explore how the different generations view the trends and influences that impact their work; and their attitudes towards technology, communication, work/life balance, organisational loyalty, attraction, engagement and retention. The study uses a multi-phase qualitative approach and includes in-depth interviews with a range of Australian industry experts; discussion groups held with Gen Ys, Gen Xers and Baby Boomer employees, in four organisations across four industry sectors; and in-depth interviews with senior executives in the same four organisations. This research will have significance to all organisations especially those that employ workers from across the generations and who are managing a multigenerational workforce. The findings will have practical application to organisational policy development in areas such as, work/life balance, attraction, engagement and retention of employees, reward and recognition systems, technology in the workplace and training and development. The study adds to the body of knowledge in workforce management, and in particular to the emerging body of knowledge on generational cohort analysis of the workplace in the Australian context. The study found significant generational differences that when harnessed and managed effectively, can contribute to the output and performance of the organisation as a whole.

Canada’s aging population is expected to have an impact on all public institutions; for public libraries, the emergence of a large, multi-generational user group of older adults challenges the current paradigm of services to seniors. This thesis examines a subset of this user group: baby boomer library patrons who are in a caring relationship with elders. It investigates how these patrons interact with the public library both for themselves, and as carers, in order to reveal library-related issues particular to this growing segment of the population. The study takes place within a conceptual framework derived from the ethic of care, and from emerging theories of library-as-place rooted in the fields of human geography and sociology. Using a qualitative instrumental case study method, long form interviews were conducted with respondents recruited through theoretical sampling extended by snowball sampling. While not generalizable, findings suggest that while these baby boomer respondents value their libraries deeply, there is potential to create services and practices more attuned to the needs of older adults who are in relationships with elders.

Emotional design addresses peoples needs and desires which is at the center of product or technology development. Currently, there is no established process of emotional design in the field of industrial design to address research and design issues. A five step emotional design process is proposed in this thesis. Research theories and methods on emotional design were reviewed. Existing pantry storage products were evaluated. User research was targeted on women between age 45 and 60. Research data were collected through interviews and surveys. Research findings were produced by analyzing the data using a proposed data analysis method called Product Emotion Baseline. Product function design, product interface design and user experience study on smart pantry were presented. All five steps of emotional design process were applied to smart pantry design to illustrate in detail how the proposed process works.

This dissertation examined health care utilization patterns across conventional health care (CHC), complementary and alternative medicine (CAM), and public health care (PHC) systems among Canadians aged fifty and older. I argued that utilization research is currently limited by a primary focus on discrete use of health care services, largely within the CHC system (i.e., medical doctors, specialists, hospitals). However substantial growth in use of CAM and PHC, particularly among late middle-age cohorts, suggests the need to widen the research lens from discretionary service use within health care systems to include medical pluralism or use across health care systems. To address the lack of research on medical pluralism and the need for a comprehensive overview of service use, I used two different strategies to create discrete patterns of service use and non-use. To frame the predictors of these patterns, a medical pluralism paradigm was proposed, which suggests that there are distinct social location and health characteristics that may explain use across health care systems. Five hypotheses were tested using data pooled from two cycles of the Canadian Community Health Survey (Cycles 2.1 [2003] and 3.1 [2005]) to create an overall sample (n=117,824). Results from the deductive (variable oriented) and inductive (person centred) strategies were compared. Differences in both the number and form of patterns are apparent. Across both strategies, the most common pattern is dual use of CHC (medical visits, specialist visits) and PHC (flu shots, sex-specific screening) but not CAM (chiropractors, other CAM providers). Consistent with the literature, women use more types of services overall than do men. The gender effect is significantly mediated by age: older men are less likely to use services across the three health care systems than older women. Strong evidence for a socioeconomic gradient in medical pluralism is also found. Higher levels of income and education increase the likelihood of using services across the three health care systems compared to low and middle levels of both income and education. The relationship between race and health service use was much less significant. Long-term immigrants demonstrate tri-use patterns close to those of Canadian born individuals; however, service differentials remain even after controlling for health needs, in favour of native-born Canadians. Medical pluralism is also associated with health related-need as support was found for both illness and wellness care. Lastly, regional differences point to a greater likelihood of medical pluralism in western Canada, but not always in urban areas. In future, a longitudinal examination of medical pluralism is necessary and would help establish the sequencing of services and how services are used in relation to the disablement process. Health policy would thus benefit from insight into the extent of service duplication for specific conditions and clarify the role of medical doctors in referral processes. / Graduate

Formal succession planning strategies for retiring Baby Boomer generation of leaders in nonprofit organizations (NPOs) are nonexistent in many NPOs, including faith-based NPOs. Top NPO leaders possess vital organizational knowledge and experience. The lack of strategic succession planning adversely affects organizational sustainability and mission fulfillment. Guided by the conceptual framework of knowledge transfer, the current study supplies a description of succession planning strategies used in faith-based organizations that have Boomer leaders. This multiple case study included 3 faith-based NPOs in Miami-Dade and Broward Counties in Florida and their top-level leaders. They supplied descriptions of formal succession planning strategies through semistructured interviews and through related organizational documents. An inductive analysis of the data revealed that (a) key leaders were the initiators for developing a strategic plan for succession, (b) boards of directors were critical to the process, and (c) leadership transition, planned or unplanned, required preparation and documented policies that must be reviewed at regular intervals. Leadership development is a valuable practice, which contributes to succession planning strategy. Influential leaders and board members of NPOs may receive inspiration to engage in succession planning strategies to maintain capable and prepared leaders at the top levels of the organizations as a means to ensure organizational sustainability and mission fulfillment. Positive social change happens in communities by encouraging a positive societal culture and identity through uninterrupted NPO services and programs. Improving the lives of community members enhances the communities in which they live.
