Aiming to select genotypes with potential to be used in a disease management, there were 50 genotypes of lima bean evaluated in relation to an isolate of S. rolfsii. Plants with 10 days old were inoculated by an injury into their base and deposited the sclerotia of the pathogen. The evaluation occurred at the 10th day after the inoculating, by calculating the percentage of the number of plants with symptoms in relation to the total of plants per pot. Most part of the genotypes (58%) behaved as highly susceptible to the pathogen while 28% were classified as susceptible, 10% as moderately resistant. Only two genotypes (F-2 and F-25) behaved as extremely resistant, corresponding to 4% of the total. The stability of resistance of these two genotypes was evaluated in relation to 10 isolates of S. rolfsii. Both genotypes showed a good level of resistance, thus demonstrating the potential of its use as a strategy for management of collar rot of the lima bean crop. / A podridão do colo, causada por Sclerotium rolfsii, é uma importante doença que pode incidir em fava (Phaseolus lunatus L.) no Nordeste brasileiro. Visando selecionar genótipos com potencial de utilização no manejo da doença, foram avaliados 50 genótipos de fava, em relação a um isolado de S. rolfsii. Plantas com 10 dias de idade foram inoculadas pelo método de ferimento do colo e deposição do escleródio do patógeno. A avaliação ocorreu aos 10 dias após a inoculação pela mensuração da incidência da doença, considerando a porcentagem de plantas com sintomas em relação ao total de plantas por vaso. A maioria dos genótipos (58%) se comportou como altamente suscetível ao patógeno, enquanto que 28% foram classificadas como suscetíveis e 10% como medianamente resistentes. Somente dois genótipos (F-2 e F-25) se comportaram como altamente resistentes, correspondendo a 4% do total. A estabilidade da resistência destes dois genótipos foi avaliada em relação a 10 isolados de S. rolfsii. Ambos os genótipos apresentaram um bom nível de resistência, demonstrando potencial de utilização como estratégia de manejo da podridão do colo na cultura da fava.

The purpose of this dissertation research was to bring voice to university custodians as blue-collar workers by exploring the manner in which four custodians interact with students on a university campus. The following research questions framed this study: 1) In what ways do four campus custodians interact with students during their work day at a large public university? 2) In what ways do those custodians talk about students and their interactions with students? This study adopted a critical philosophical lens that acknowledged the historically-marginalized voice of custodians as campus blue-collar workers. Extant research on blue-collar worker identity theory and college student-staff interactions and mentoring literature, as well as the author's own blue-collar background, informed and framed the study. Qualitative data sources for this ethnographically-grounded case study were four campus custodians employed in three residence halls during the academic year at a large, public university in the Midwest. A moderate participant observation strategy melded with a semi-structured interview protocol were employed. Data were collected and transcribed during seventy-five hours of observations throughout a six-week time span. Mutual benefits to both college student success and custodial staff occupational esteem were identified in custodial staff-student interactions. More specifically, custodial staff participants were found to indirectly support college student success via formally acknowledged and performed cleaning and maintenance duties of observing, protecting, and promoting the health of college students. Additionally, custodial staff directly supported college student success via informally-performed actions of remembering, comforting, advising, exchanging and keeping gifts, and participating in events with students. Based on these findings, this study advises college and university decision-makers to consider custodians as important mentors for, and allies to, college student success. Suggestions for professional practice include 1) Acknowledging and leveraging custodians' unique assets and contributions, 2) Fostering relationships between students and custodians, 3) Increasing custodian's opportunities for professional development, 4) Considering custodians' potential to support student success in custodian hiring decisions, and 5) Training Custodial Staff in Basic Crisis Intervention. Future research should examine custodians as formal mentors, explore social justice concerns relative to blue-collar campus workers, and study the influence of custodian-student interactions on custodial staff job satisfaction and performance.

Union mergers have occurred since unions were first established. Research on this particular aspect of the union movement is well established in the UK and the US. However, there are few studies of Australian union mergers, despite the fact that many Australian unions took part in a 'merger boom' in the 1980s and 1990s. Two of the few Australian studies, Hocking (1996) and Campling and Michelson (1998), utilised resource dependency and strategic choice theories to ascertain the why and how of union mergers. However, these Australian studies, like their UK and US counterparts, cease with the completion of the merger and, consequently, there is little known of the post-merger operation of unions. How does the integration of the merger partners - with their traditions, structures and financial arrangements - occur? This thesis rectifies the gap in the literature by means of a qualitative, longitudinal study of the merger and post-merger activities of one of the largest and most prominent unions in Australia, the Australian Manufacturing Workers' Union (AMWU), as it moved towards complete amalgamation. The thesis examines the period 1995-2003. Four of the five pre-merger unions faced a serious and continued decline in membership and all faced mounting financial deficits. From 1995, the year the various mergers were completed, membership decline continued and financial resources dwindled further, providing the impetus for further and significant post-merger changes. The analysis demonstrates that, due to a continuing lack of financial resources, the AMWU leadership initiated a budgeting strategy which influenced the actions and changed the opinions of many of the Union's officials, guiding them towards accepting integration of the constituent divisions and near complete amalgamation. The thesis answers the questions of why and how a union moves from a negotiated federated structure towards amalgamation, post merger, with a particular focus on financial decision-making processes.

'Corporate warriors' and 'company animals' are common terms used to describe Japanese sarariman ( salarymen ), the former referring to salarymen as the samurai of Japan's post - war economic miracle and the latter suggesting servile creatures of Japanese corporations. This thesis explores Japanese salaryman masculinity, that is, the 'hegemonic masculinity' in Japan. The study collects the life - histories of 39 men across three generations of salarymen, so that the oldest men in my sample were in their 70s and the youngest in their 20s. While research on Japanese masculinities has expanded rapidly in recent years, no other study, to the author's knowledge, explores generational changes. This generational approach allows exploration of maintenance of and changes in hegemonic masculinity over time. This thesis pays attention to the phases of salarymen's lives. In the period of growing up, participants were continually confirmed in their self - worth through a hierarchy grounded on age and gender in the settings of the family, school and neighbourhood. Across the three generations, participants grew up in a homosocial and heterosexual world, barely mixing with the opposite sex and focusing on educational outcomes for successful careers after their schooling. Despite their immersion in comradeship, most participants ensconced themselves comfortably in the institution of marriage. While a few unconventional families emerged in the sons' generation, the traditional gendered division of labour is reproduced across the three generations. Many participants rejected equal opportunities for women in the workforce and participated very little in housework and childcare, claiming that providing the family income was their 'childcare'. Participants understood themselves as corporate warriors, or elite male workers, rather than company animals. Nevertheless, some young respondents evinced a tinge of jealousy for increasing number of ' freeters ' ( part - time workers ). Moreover, several men in the grandfathers' generation regretted their current minimal contact with their children and grandchildren as a result of their absence from home while children were growing up. Thus Japanese salarymen in this study expressed aspects of both the corporate warrior and the company animal in reflecting on their experiences. / Thesis (Ph.D.)--School of Social Sciences, 2006.

Följande undersökning behandlar ämnet rekrytering med inriktning på kompetensens betydelse vid tillsättning av en tjänst. Vidare redogörs för hur rekryteringsföretag i en mellanstor svensk stad väljer ut individer ur en grupp av arbetssökande och på vilka premisser urvalen sker. Det vill säga om en arbetssökande väljs ut att bli tillsatt för en tjänst på grund av vederbörandes arbetserfarenhet, kunskap och utbildning, eller om det är tack vare dennes personliga egenskaper. Studien ämnar undersöka i vilken utsträckning ansvariga rekryterare värderar arbetssökandes formella kompetenser i förhållande till dess informella kompetenser. Undersökningen kommer också studera den estetiska kompetensens betydelse vid rekrytering. Med andra ord betydelsen av att som sökande klä sig rätt, komma hel och ren till arbetsintervjun. För studien använder vi oss av en kvalitativ metod i form av intervjuer. Dessa intervjuer är baserade på frågor från en upprättad intervjuguide som går att ta del av i slutet av uppsatsen som en bilaga. Dessa frågor resulterar i information från respondenterna som möjliggör för oss att besvara våra frågeställningar som presenteras i inledningen av denna undersökning. I undersökningen framkommer det att rekryterarna framhäver vikten av formell och informell kompetens beroende på vilken typ av tjänst som skall tillsättas. För rekryteringar på kollektivsidan tar man mer hänsyn till vad den sökande besitter för faktiskta kompetenser. Det vill säga vilka direkta kunskaper individen har som går att omsätta i arbetet, till exempel om den sökande kan köra truck och har körkort för detta. Om individen i fråga har akademisk bakgrund eller ej är mindre intressant för dessa jobb och rekryteringsprocesserna sker i regel snabbare än på tjänstemannasidan. Rekryteringar på tjänstemannasidan är istället mer omfattande, komplicerade och tidskrävande. Här läggs tonvikten på den sökandes akademiska bakgrund och arbetserfarenhet. På den formella kompetensen ställs i regel höga krav vid tillsättning av tjänstemän. Studien har visat att det första intrycket av den arbetssökande har betydelse för den ansvarige rekryteraren när de möts för en intervju. En sökande som kommer ordentligt klädd och har förmågan att presentera och framföra sig själv på ett tilltalande sätt har större chanser till en anställning än den individ som inte anstränger nämnvärt. / The following study deals with the subject recruitment, focusing on the competence relevant for appointment to a post. Furthermore it describes how the recruitment companies of a medium-sized Swedish city will select individuals from a group of candidates and on which premises the samples occurs. That is, if a job applicant is selected to be hired because of his work experience, knowledge and education, or if it is thanks to his personal qualities. The study intends to examine the extent to which responsible recruiters value the job seekers formal competences in relation to its informal competences. This study will examine the aesthetic competences importance in the recruitment process. In other words, the importance of the candidates to dress properly, be clean and tidy to the interview. For the study, we use a qualitative approach through interviews. These interviews are based on questions from a prepared interview guide that you can take part of at the end of the essay as an appendix. These questions will result in information from the respondents that will enable us to answer our question as mentioned in the introduction to this study. In the survey, it appears that recruiters emphasize the importance of formal and informal skills depending on the type of post to be appointed. When it comes to recruitment of blue-collar workers the recruiters takes more consideration of which actual skills the candidate possess. That is, which direct knowledge the individual have that he’s able to use at work, for example, if the applicant can drive a forklift and has a license to drive it. If the individual in question has an academic background or not is less interesting for these kinds of jobs and the recruitment processes are generally faster than the white-collar worker side. Recruitment at the white-collar side, is more extensive, complicated and time consuming. Here the emphasis is placed on the candidate's academic background and their work experience. When it comes to the formal qualifications there are usually high requirements for the employment of white-collar workers. The study has shown that the first impression of the job applicant is important for the responsible recruiter when they meet for an interview. An applicant that arrives properly dressed and have the ability to present and express himself in an appealing way have a greater chance of employment than the individual who doesn’t make an effort.

Bridge failures are generally resulted from scour of the bed material around bridge piers and abutments during severe floods. In this study, scour phenomenon around bridge abutments and collars, located at abutments as scour countermeasures, were experimentally studied. The experimental study was carried out under clear-water scour conditions with uniform non-cohesive sediment (having a grain size diameter of d50=0.90 mm). The experimental flume is a rectangular channel of 30 m long and 1.5 m wide filled with this erodible bed material. Based on the results of 97 experiments conducted during the study, the efficiency of various sizes of collars, which were used to reduce the local scour depth, located at different elevations around the abutments was determined. The results obtained were compared with previous studies, and the effect of the sediment grain size on the performance of abutment collars was emphasized. It was noticed that when the collar width was increased and placed at or below the bed level, the reduction in scour depth increases considerably. It was also found out that the change of the sediment size did not affect the optimum location of the collar at the abutment, which yields the maximum scour reduction around the abutment.

During severe floods, bed material around bridge piers and abutments are scoured by the flow and as a result, bridges are subject to damages. These damages are mostly unrepairable and can result in loss of lives and property. In this thesis study, abutment scour under clear-water condition was investigated and collars were tested as scour countermeasures around the abutments. The experimental study was carried out in a rectangular channel with an almost uniform cohesionless bed material of d50=1.50 mm for a test period of 3-hours. The channel was 28.5 m long and 1.5 m wide. The erodible bed material was placed into the test section that was 5.8 m long and 0.48 m deep. For this thesis study, 60 experiments were carried out with and without various collars placed at different elevations around the abutments. The scour formation around the abutments with collars was observed and scour reduction efficiencies of the collars were studied. Experiment results were compared with the previous studies of Dogan (2008) and Kayat&uuml / rk (2005) in terms of sediment size, abutment shape and flow depth, and the effects of these factors on collar&#039 / s scour reduction efficiency were studied. Based on the results of the experimental studies, it was observed that scour depths decreased as the collar width increased and the collar placed deeper into the sediment bed for a given abutment length. When the present study and the previous studies were compared, it was observed that sediment size and flow depth had no significant effect on the scour reduction performances of the collars.

The major damage to bridges occurs due to scour of the bed materials around piers and abutments during severe floods. This study involves the experimental investigations of the various scour patterns forming around abutment models tested with and without collars as scour countermeasures. The experiments were conducted in a rectangular channel under clear-water scour conditions. In the first part of this study, 34 experiments were conducted with semi-circular end abutment models with and without a collar for a period of 3 hours. Collars of various sizes were placed at different elevations on the abutment models, and the scour reduction efficiencies of collars were investigated for the different flow depths. Based on the results of the experimental studies, the optimum locations of collars on the abutments, which result in minimum scour depth around the abutments, are obtained at the bed level and below the bed level depending on the flow intensity values. In the second part of this study, the effects of flow depth and abutment length on the temporal development of local scour at bridge abutments were studied. 20 experiments were performed without collars for a time period of 8 hours. It was observed that at the upstream of the abutment, the depth of the local scour increases rapidly within the first three hours of the experiment for the different flow depths.
