The Job Searching and Career Expectations of Recent College Graduates: An Application of the Expectancy Violations Theory of Communication

Smith, Stephanie Ann January 2015 (has links)
Current U.S. college graduates are part of the millennial generation, which is the largest and most well-educated generation of all time (PEW, 2014; Twenge, 2006) and are the future of the workforce. Moreover, recent college graduates have unique job searching and career expectations, which underlie the communication strategies used to search for jobs. While the process of job searching is inherently communicative in nature, job searching is an under studied context within communication research. Although previous research outlines the career related expectations of young job seekers, it fails to examine how recent college graduates search for jobs and communicatively respond to violated job searching expectations. This goal of this study was to determine the communicative strategies recent college graduates use to search for jobs and the role communication plays in responding to job searching expectation violations. Expectancy violations theory (Burgoon, 1978), a communicative framework, is applied in this study to understand how recent college graduates respond to violated job searching expectations. Six research questions guided this study to determine the job searching communication strategies, job searching expectations, career expectations, and expectancy violations that occurred throughout the job search. To answer these questions, I conducted interviews with 20 participants, twice over a three-month period, to qualitatively understand and analyze the job searching processes of recent college graduates. The findings from this study demonstrate that recent college graduates use a combination of traditional job searching strategies and online social networking strategies to find, research, and apply for jobs. While participants expected the job search to be difficult, they were surprised at the amount of intensity and effort job searching required. Interpreting the results through the lens of EVT helped note that the participants with the most realistic job searching and career related expectations had greater success job searching over a three-month period and at the time of the follow up interview, several participants had accepted full-time, post graduate jobs. Expectancy violations theory was essential in interpreting how participants network with interpersonal contacts by offering insight for why participants strategically communicate with contacts based upon their potential reward value. The reciprocation and compensation mechanisms of expectancy violations theory also provided an explanation as to why some participants increased their job searching activity in response to violated expectations and others did not. An especially interesting finding illustrates that participants preferred to receive bad news over no news at all, and even evaluated bad news as a positive expectancy violation because it reduced their uncertainty. Collectively, expectancy violations theory (Burgoon, 1978) and anticipatory socialization research (Dubinsky, Howell, Ingram, & Bellenger, 1986) highlight how recent college graduates form their job searching and career expectations. The findings from this study also contribute to existing job searching research by examining the job searching strategies and behaviors of recent college graduates to better understand how they job search and what they expect from their future employers. Lastly, the findings from this study provide several practical application suggestions for organizations to implement in order to recruit and retain the best young job seekers in light of their current expectations and job searching strategies.

Studier över bebyggelsenamn i Västerbottens län / Studies of habitative names in the county of Västerbotten

Hagervall, Claes Börje January 1986 (has links)
The thesis consists of the following papers: (1) Tre ortnamn på Spöl-. (Tre Kulturer. 2. Medlemsbokför Johan Nordlander-sällskapet tillägnad minnet av Roland Otterbjörk 1925-1984. Umeå 1985. ISSN 0281-9546.) (2) Ortnamnen i Västerbottens län. Del 14, Vännäs kommun, A Bebyggelsenamn. Umeå 1986. ISBN 91-86372-10-6. (Övre Norrlands ortnamn. ISSN 0348-7237.) (3) Studier över yngre nybyggesnamn i Västerbottens län, särskilt i Vännäs socken. Umeå 1986. ISBN 91-7174-237-9. (Nordsvenska. 2. Skrifter utgivna av Institutionen för nordiska språk vid Umeå uni­versitet. ISSN 0282-7182.) The chief aim of the thesis is to describe and etymologize the habitative names in the parish of Vännäs in the county of Västerbotten, northern Sweden. The material used consists of place-name forms recorded in the local dialects. The material forms the basis of the author's hypotheses concerning sound changes and morphological changes and the original significance of the various place-names. The hypotheses have been tested by confronting them with historical data concerning the settlement of the area, with linguistic material, with parallel place-names and with topographical data. The purpose of the third paper is to draw further conclusions about the naming of the younger settlements (i.e. settlements from the 18th and the 19th centuries) in the county of Västerbotten as a whole. To shed light on this problem a large number of similar younger habitative names in the area have been examined. The main result of this study is that a number of the second elements of these names can be considered topographically non-motivated and suffixlike. Another result is that the interference from the authorities concerning the direct naming of the young settlements is pro­bably insignificant. / digitalisering@umu

Geomorfologia e sedimentologia dos depósitos sedimentares recentes da porção superior do Estuário do Rio Pará (Baía de Marajó, Amazônia)

Martins, Silvio Eduardo Matos January 2010 (has links)
A dissertação visa caracterizar os depósitos sedimentares superficiais da planície arenosa de maré e de fundo/canal da porção superior da baía de Marajó, na área de influencia do Porto de Vila do Conde quanto sua geomorfologia, distribuição sedimentar e assembléia mineralógica de fundo, com ênfase nos minerais pesados. Os sedimentos foram classificados em nove classes texturais. A granulometria variou de argila à matacão. Os principais minerais pesados que ocorrem nos depósitos superficiais são: zircão, estaurolita, turmalina, cianita, granada e rutilo. Secundariamente ocorrem sillimanita, andaluzita, epidoto, apatita, topázio, muscovita, tremolita-actinolita, hornblenda, diopsídio, monazita, augita e biotita. Os grãos de estaurolita, zircão, turmalina e cianita apresentam ampla distribuição em todas as amostras dos sedimentos de fundo e planície. A assembléia mineralógica de pesados indica mais de uma área fonte de sedimentos. As feições geomorfológicas do curso fluvial estudado puderam ser descritas quanto suas formas, profundidades e composições sedimentares. A distribuição sedimentológica apresenta estreita relação com a morfologia e, sobretudo, evidencia as características de alta hidrodinâmica para esta área. Os sedimentos nas planícies de maré arenosas, localmente denominadas de “praias” de uma forma geral, ocorrem pela deposição de material arenoso fino, mal selecionado. Tais áreas, continuamente, recebem sedimento, de origem terciária, devido à proximidade com os afloramentos do grupo Barreiras. A suíte de minerais indica uma proveniência potencial de rochas metassedimentares, metamórficas de alto, médio e baixo grau e ígneas que afloram nas adjacências da área, tais quais de forma primaria a formação Barreiras e pós-Barreiras e secundariamente o complexo cristalino Xingu e o grupo Tocantins. / The dissertation aims to characterize the bottom sediments deposits of the tidal sandy plain and bottom/channel of the upper portion Marajó Bay, in area of the port of Vila do Conde about your geomorphology, sediment distribution and mineralogical assembly background, with emphasis on heavy minerals. The sediments were classified into nine textural classes. The particle size ranged from clay to boulder. The main heavy minerals that occur in the superficial deposits are zircon, staurolite, tourmaline, kyanite, garnet and rutile. Secondly occur sillimanite, andalusite, epidote, apatite, topaz, muscovite, tremolite-actinolite, hornblende, diopside, monazite, augite and biotite. The grains of staurolite, zircon, tourmaline and kyanite are widely distributed in all samples of bottom and tidal plain sediments. The heavy mineral assemblage indicates more than one source area of sediments. The geomorphological features of the studied river course could be described as their shapes, depths and sedimentary compositions. Features of sedimentological distribution are closely related to the morphology and, especially, highlights high hydrodynamics for this area. The sediments in sandy tidal flats, locally called "beaches" in general, occur by the deposition of fine sandy material, poorly selected. Such areas continuously receive sediment of Tertiary origin, due to the proximity of the outcrops of the Barriers group. The mineral suite indicates a potential provenance, metasedimentary rocks, metamorphic high, medium and low grade and igneous rocks that outcrop in the vicinity of the area, in a primary form the Barriers formation and post-Barriers and, then the Xingu crystalline complex and Tocantins group.

Social Capital, HIV Risk Behavior and Substance Use among Recent Latino Immigrants in South Florida

Cyrus, Elena 10 October 2013 (has links)
Social capital, or social cohesion or group connectedness, can influence both HIV risk behavior and substance use. Because recent immigrants undergo a change in environment, one of the consequences can be a change in social capital. There may be an association among changes in social capital, and HIV risk behavior and substance use post immigration. The dissertation focused on the interface of these three variables among recent Latino immigrants (RLIs) in South Florida. The first manuscript is a systematic review of social capital and HIV risk behavior, and served as a partial background for the second and third manuscripts. Twelve papers with a measure of social capital as an independent variable and HIV risk as the dependent variable were included in the analysis. Eleven studies measured social capital at the individual level, and one study measured social capital at the group level. HIV risk was influenced by social capital, but the type of influence was dependent on the type of social capital and on the study population. Cognitive social capital, or levels of collective action, was protective against HIV in both men and women. The role of structural social capital, or levels of civic engagement/group participation, on HIV risk was dependent on the type of structural social capital and varied by gender. Microfinance programs and functional group participation were protective for women, while dysfunctional group participation and peer-level support may have increased HIV risk among men. The second manuscript was an original study assessing changes in social capital and HIV risk behavior pre to post immigration among RLIs in South Florida (n=527). HIV risk behavior was assessed through the frequency of vaginal-penile condom use, and the number of sexual partners. It was a longitudinal study using secondary data analysis to assess changes in social capital and HIV risk behavior pre immigration to two years post immigration, and to determine if there was a relationship between the two variables. There was an 8% decrease in total social capital (p ˂ .05). Reporting of ‘Never use’ of condoms in the past 90 days increased in all subcategories (p ˂ .05). Single men had a decrease in number of sexual partners (p ˂ .05). Lower social capital measured on the dimension of ‘friend and other’ was marginally associated with fewer sexual partners. The third manuscript was another original study looking at the association between social capital and substance use among RLIs in South Florida (n=527). Substance use with measured by frequency of hazardous alcoholic drinking, and illicit drug use. It was a longitudinal study of social capital and substance-use from pre to two years post immigration. Post-immigration, social capital, hazardous drinking and illicit drug use decreased (p˂.001). After adjusting for time, compared to males, females were less likely to engage in hazardous drinking (OR=.31, p˂.001), and less likely to engage in illicit drug use (OR=.67, p=.01). Documentation status was a moderator between social capital and illicit drug use. ‘Business’ and ‘Agency’ social capital were associated with changes in illicit drug use for documented immigrants. After adjusting for gender and marital status, on average, documented immigrants with a one-unit increase in ‘business’ social capital were 1.2 times more likely to engage in illicit drug use (p˂.01), and documented immigrants with one-unit increase in ‘agency’ social capital were 38% less likely to engage in illicit drug use (p˂.01). ‘Friend and other’ social capital was associated with a decrease in illicit drug use among undocumented immigrants. After adjusting for gender and marital status, on average, undocumented immigrants with a one-unit increase in ‘friend and other’ social capital were 45% less likely to engage in hazardous drinking and 44% less likely to use illicit drugs (p˂.01, p˂.05). Studying these three domains is relevant because HIV continues to be a public health issue, particularly in Miami-Dade County, which is ranked among other U.S. regions with high rates of HIV/AIDS prevalence. Substance use is associated with HIV risk behavior; in most studies, increased substance use is associated with increased chances of HIV risk behavior. Immigration, which is the hypothesized catalyst for the change in social capital, has an impact on the dynamic of a society. Greater immigration can be burdensome on the host country’s societal resources; however immigrants are also potentially a source of additional skilled labor for the workforce. Therefore, successful adaption of immigrants can have a positive influence on receiving communities. With Florida being a major receiver of immigrants to the U.S, this dissertation attempts to address an important public health issue for South Florida and the U.S. at large.

Estrutura populacional e história demográfica da tartaruga-verde (Chelonia mydas) no Atlântico Oeste / Population structure and demographic history of green turtle (Chelonia mydas) in the West Atlantic

Juliana Costa Jordão 03 October 2013 (has links)
As tartarugas marinhas são répteis de vida longa que realizam extensas migrações entre áreas de alimentação e desova, resultando em estágios sucessivos de mistura e isolamento de estoques genéticos, espacial e temporalmente. A tartaruga-verde (Chelonia mydas) está ameaçada de extinção, e é fundamental entender sua dinâmica populacional e distribuição para o manejo e conservação da espécie. O objetivo deste estudo foi analisar a diversidade genética, estrutura populacional, origens dos indivíduos e história demográfica de C. mydas em três locais do Oceano Atlântico (estado do Rio de Janeiro, Brasil - área de alimentação; Guadalupe e Guiana Francesa - áreas de desova), com base em sequências da região controle do DNA mitocondrial (mtDNA) e 10 loci de microssatélites. As análises de mtDNA demonstraram que a área amostrada no Brasil tem perfil genético semelhante às outras áreas de alimentação da costa brasileira. De maneira semelhante, o perfil genético das duas áreas de desova é bastante similar ao de outros sítios reprodutivos na região do Caribe. As análises de estoque misto revelaram que os indivíduos juvenis no Brasil são provenientes principalmente da Ilha Ascensão, Guiana Francesa e Guiné Bissau. Os microssatélites detectaram estrutura genética entre as três populações, apesar de haver um fluxo de migrantes entre elas, especialmente de indivíduos da Guiana Francesa em direção ao Brasil e Guadalupe. Guiana Francesa, Guadalupe e Brasil apresentaram declínio populacional severo, detectado pelos microssatélites. Apesar da distribuição global, as populações de tartarugas-verdes estão sujeitas a diferentes pressões nos habitats que ocupam, e é importante entender quais populações estão ameaçadas. Este estudo enfatiza a importância da conectividade entre áreas de alimentação e desova que podem estar amplamente distribuídas de acordo com oportunidades ou restrições ecológicas, adicionando informações a respeito da dispersão e a dinâmica de tartarugas-verdes que frequentam o Oceano Atlântico / Sea turtles are reptiles with a long lifespan that undertake wide-ranging migrations through feeding and nesting sites, resulting in successive stages of mixing and isolating genetic stocks, both spatially and temporally. The green sea turtle (Chelonia mydas) is threatened with extinction, and it is essential to understand its population dynamics and distribution in order to manage and preserve the species. The aim of this study was to analyze the genetic diversity, population structure, natal origins and demographic history of C. mydas in three sites in the Atlantic Ocean (Rio de Janeiro state, Brazil - feeding ground; Guadeloupe and French Guiana - nesting sites), based on sequences of the mitochondrial DNA (mtDNA) control region and 10 microsatellites loci. The mtDNA analyses demonstrated that Brazilian samples have the same genetic profile of others collected in feeding grounds in the Brazilian coast. Similarly, the genetic profile of the nesting sites has resemblances to others in the Caribbean region. The mixed stock analyses revealed that most of the juveniles in Rio de Janeiro state come from Ascension Island, French Guiana and Guinea Bissau. Microsatellites detected genetic structure among the three populations, even with migration flows, especially in individuals from French Guiana to Brazil and Guadeloupe. French Guiana, Guadeloupe and Brazil presented a severe population decline, detected by the microsatellites analyses. Despite the worldwide distribution, green sea turtle populations undergo different pressures at the habitats they occupy, and it is important to understand which populations are threatened. This study emphasizes the importance of connecting nesting and feeding areas that can be widely distributed according to ecological opportunities or constraints, adding information on dispersion and population dynamics of green sea turtles on Atlantic Ocean
