Este trabalho teve como objetivo estudar de maneira exploratória a segmentação por meio de coortes, através de sua literatura e da opinião de profissionais e especialistas de marketing sobre o tema. Buscando verificar a influência das coortes na estratégia de marketing e analisar as tendências da pesquisa realizada anteriormente, algumas etapas foram executadas. Primeiramente, foi conduzida uma revisão da literatura, buscando responder o tema de pesquisa colocado. A revisão focou nos temas de segmentação, gerações e coortes e seus componentes ligados a cultura, a valores e sub-culturas e grupos de referência, levantando os mais recentes estudos tanto nacionais como internacionais. Após isso, como método de pesquisa escolheu-se a pesquisa qualitativa por meio de entrevistadas em profundidade. A análise dos dados coletados foram analisados por meio de análise de conteúdo, com o auxílio do software NVivo8. As entrevistas conduziram a situações em marketing nas quais a segmentação por meio de coortes foi relevante, permitiram comparar posicionamentos e levou a construção de um mapa causal com os principais conceitos observados na pesquisa. / This work had as primary objective study the segmentation by cohorts. Beyond this, verify the cohorts influence and analyze the research trends were secondary objectives. Literature review and professional and researchers opinions were collected about the objective. To attain these objectives, some stages needed to be transposed. Firstly, the literature review was conducted, searching to answer the research theme proposed. The literature review focused on the themes of market segmentation, generations and cohorts, and its components such as culture, values, sub-cultures and references groups, analyzing Brazilians and international researches. After this, as research method was chosen the qualitative method by in-depth interviews. Collected data were analyzed by content analysis, helped by software NVIVO8. The interviews showed marketing situations where cohorts segmentation could help the marketing managers. After these, marketing researchers were interviewed and a causal map was drown, connecting the concepts collected during the research.

Job satisfaction in law enforcement is important because it promotes continuity of a professional and cohesive police force that works well together, follows proper policy and procedures, and provides the services needed to the public. Given multigenerational law enforcement officers are now working together, its impact on job satisfaction is not known. This study focused on how generational cohort membership impacts the job satisfaction of law enforcement officers based on Mannheim's theory of generations and Locke's range of affect theory. It utilized a survey design where job satisfaction was assessed using the Job Descriptive Index, Organizational Commitment Questionnaire, and Job Task Questionnaire. A quantitative analysis was employed using a correlation design, multiple regression, and an ANOVA. Findings showed significant differences at the .05 level in frequency ratings on the job task questionnaire on patrol, traffic enforcement, and warrant service between the generations. A logistical regression of Job Descriptive Index scores showed a significant relationship between generational cohort membership and job satisfaction scores on the promotion scale, supervision scale, and the job in general scale. Lastly, a logistical regression of the Occupational Commitment Questionnaire showed significance between Generation X and Millennial officer's overall scores with Millennial's having lower organizational commitment. Implications for social change include increasing knowledge for patrol officers and their supervisors regarding these generational differences. Other social change includes training programs for current and future officers on understanding and working with these generational differences in law enforcement.

Since the beginning of the 2000s, unique challenges for a multigenerational workforce (MW) using different types of current technology (CT), informational and noninformational, at an increasing rate have surfaced. Necessary considerations were made among companies using these types of CT that changed frequently and influenced employee efficiency (EE) and organizational productivity (OP), leading to an under-identified impact on management decisions. The problem addressed in this study was the difficulty management had in managing work tasks and activities when CT was used in a MW. Most of the Baby Boomer generation will be retiring over the next decade, thus compromising and leaving a major gap in skills, experience, and talent. The purpose of this quantitative research study was to study the effects of multigenerational cohorts (MC), gender (GEN), CT, experience (EXP), and voluntariness of use (VU) (independent variables [IVs]), among a MW and their impact on EE and OP (dependent variables [DVs]). Two research questions were used that focused on the relationship between the IVs and DVs. Positivism was used as the theoretical framework. A convenience sampling approach was used to select participants. The participants were full-time employees between 23 and 71 years of age in the continental United States. Multiple and stepwise regression analyses was used to investigate the relationship between the IVs and the DVs. Results showed that only IVs type of CT and VU had a significant effect on EE and OP. These findings may contribute to positive social change by helping organizations create comprehensive and explicit business models of efficiency and productivity among a MW.

This research is a systematic comparison of youth migration experiences between two birth cohorts, using the first ten rounds of two national longitudinal surveys of youth, NLSY79 and NLSY97. Results show both changes and continuities in youth migration patterns across cohorts for ages16-25. Specifically, youth today have a delayed but stronger migration momentum than the late baby boom generation, the dividing point being at age 22. Women are more likely to migrate than men in the recent cohort, but not in the older cohort. Whites migrate considerably more than blacks and Hispanics consistently across cohorts. The likely life events in youth's transition to adulthood are important indicators of youth's migration propensity for both cohorts. Particularly, graduating with a bachelor's degree is the most powerful predictor of youth's migration propensity. Other life events such as getting married; becoming separated, divorced, or widowed; dropping out of college; and losing a job are also significantly associated with youth migration. In general, the effects of these life events on youth's migration propensity are weakened across cohorts, but the importance of having a college degree on migration propensity has been increasing.

The elderly and persons residing in zero vehicle households require better transportation services by virtue of their need for special care and lack of mobility, respectively. An analysis of the travel trends of these population cohorts is essential to determine the best ways to improve transportation facilities to better serve them. Information about location of residence, life-cycle, differences by gender, employment status, driver status, highest level of education coupled with trip information like trip rate, travel times and distances trip purpose, modal split and percent of people immobile will facilitate understanding the factors that influence trip making among these people and help predict travel trends for the future. This work attempts to analyze the elderly and persons residing in zero vehicle households in the United States by using NHTS 2001 and NPTS 1990 datasets for the purpose of analysis and comparison.

This study explores the role of `community' within a university campus Learning Community (LC). With a cohort-based structure, an LC exists to enhance student learning through peer cooperation and participation, however the scope of what constitutes community within these cohorts is not currently understood. This study investigates the roles of individual reciprocity, communication, need, time, and physical environment in community building, utilizing qualitative interviews and observations of a 30 member LC over the course of two academic years and a four-week study abroad experience in Panama. Through this, the vital roles of the orientation period and programming staff are revealed and should be considered in order to generate more effective LCs with stronger cohort communities.

This thesis focuses on changes in the value of educational capital over time. Taking as a point of departure Pierre Bourdieu’s notion of a multidimensional social space, the thesis examines how this value is affected when educational assets—through the democratization of education—are becoming more widespread across this space (i.e. the population). The studies are based on datasets from Statistics Sweden, comprising the complete censuses of 1960 to 1990, LISA-registers, and registers of wealth and income. Different approaches are employed: the use of the Gini-coefficient to catch changes in the distribution of education; comparative models to investigate cohorts at different points in time; and specific multiple correspondence analysis to study the distribution of several assets simultaneously.  Three aspects are explored: the distributions, returns, and uses of education. Firstly, while there is a steady increase in the average number of years of schooling, there is a different pattern in the development of the distribution of education. Three phases were distinguished: one of increasing levels of inequality, one of decreasing inequality, and one in which the inequality levelled out. Secondly, the returns of education have diminished as far as economic gains are concerned, causing a fracture between different social generations, at the same time as the returns in a wider social sense have remained relatively stable. However, the relative stability hides crucial discrepancies. Groups with the lowest level of education are further marginalized and distances between ‘economic’ and ‘cultural’ groups are growing. Thirdly, in their modes of using the educational system, there are glaring differences between the economic elite and the cultural elite, although both utilize prestigious educational institutions as sites of social reproduction. The fundamental difference consists in that exclusive educational strategies are not as necessary to the dominant fraction of the economic elite. Their children are able to choose more freely among the offers of higher education.  The paradoxical development of the value of education is that while the absolute value of educational capital has decreased in general, the differences in relative value persist.

Orientador: Antonio Leão Castilho / Resumo: This is the first study to evaluate in broad spatiotemporal scales the growth parameters and population structure of Rimapenaeus constrictus, a barely damaged species composing the bycatch from shrimp fishing in the Western Atlantic. The abundance and size-class frequency distribution, growth, longevity and sex ratio were evaluated from monthly samples obtained in the northern littoral of São Paulo state from Jan/1998 to Jun/2003. We measured 5,812 individuals in which the sex ratio was skewed toward females; this was more evident in size classes greater than 10 mm in CL (carapace length) (binomial test, p<0.05). We selected 16 growth cohorts of females, and 8 of males, the majority consisting of younger individual cohorts excluded from the fisheries closure period. Growth estimates resulted in a CL∞ of 17.42 mm, a growth coefficient of 0.008 and a longevity of 579 days (1.60 year) for females, as well as a CL∞ of 16.3 mm, a growth coefficient of 0.01 and a longevity of 425 days (1.17 year) for males. Our results provide information of incontestable relevance to our knowledge of fishing management. We therefore strongly recommend that the fisheries closure period be changed to protect this species’ recruitment period and consequently its adult individuals. The reproduction and recruitment were analyzed in order to determine the size at the onset of sexual maturity, the reproductive and recruitment patterns and the copulation period. In our study, 6,456 shrimps were captured a... (Resumo completo, clicar acesso eletrônico abaixo) / Mestre

Our results provide information of incontestable relevance to our knowledge of fishing management. We therefore strongly recommend that the fisheries closure period be changed to protect this species’ recruitment period and consequently its adult individuals. The reproduction and recruitment were analyzed in order to determine the size at the onset of sexual maturity, the reproductive and recruitment patterns and the copulation period. In our study, 6,456 shrimps were captured among which 5,774 were measured, which 4,322 were females and 1,452 were males. The estimated maturity was 8.3 mm and 11.2 mm, for males and females, respectively. Reproductive females were found over the 5-year study. These results suggests a continuous reproduction pattern, with peaks in summer and in spring. We verified a positive significant relation between reproductive females and temperature (lag +1 and +3), although the decrease in bottom water temperature in some peaks of reproductive activity (spawning), which was probably induced due to SACW intrusion. The recruitment was considered episodic and even though no significant relation was found between immatures and reproductive females, we suggested that the main recruitment peaks observed were a consequence of the major reproductive activities a few months prior to it. The copulation period was continuous in the sampled period, and ISP females (recently copulated) were significant correlated with reproductive males (lag 0). Thus, we propose that during this period the sexual proportion is 1:1, probably due to the migration of reproductive males, attracted to copulate. Our results provide information of incontestable relevance to our wide knowledge of the species’ reproductive biology, in order to support an accurate fishing management. / FAPESP: 2015/13639-5
