Evaluation of Various Herbicides for Saw Greenbrier [Smilax bona-nox L.] and Southern Dewberry [Rubus trivialis Michx.] Control and Bermudagrass [Cynodon dactylon (L.) Pers.] Tolerance and Sharppod Morningglory [Ipomoea trichocarpa var. trichocarpa Ell.] Control in Roundup Ready Flex® and LibertyLink® Cotton Systems

Janak, Travis Wayne 2011 December 1900 (has links)
Field studies were conducted during 2006 and 2007 to evaluate control of saw greenbriar and southern dewberry by various pasture herbicides and to assess forage tolerance of Tifton 85 bermudagrass to these herbicides. Herbicides evaluated in each study included triclopyr, picloram, 2,4-D, fluroxypyr, dicamba, aminopyralid, metsulfuron methyl and various combinations of the above. Visual ratings were taken on each herbicide efficacy experiment. Visual evaluations of phytotoxicity, measurements of dry matter yield, and forage quality were quantified for each of the bermudagrass tolerance trials. Saw greenbriar was best controlled at approximately one year after treatment by triclopyr at 10.9% ae v/v with diesel as the carrier (88-98%), although the lower rate of triclopyr + diesel at 0.87% ae v/v + 5% v/v and triclopyr alone at 0.87% ae v/v provided 49 to 86% control. Triclopyr + fluroxypyr at 0.25% ai v/v + 0.086% ai v/v gave best control of southern dewberry in both years when applied as an individual plant treatment (IPT) six weeks after shredding. In general, shredding 45 days prior to herbicide application gave an advantage to southern dewberry control versus not shredding. In 2006, triclopyr + fluroxypyr (IPT) was the only treatment to decrease Tifton 85 dry matter yield at the first harvest, with no effect observed at the second harvest. In 2007, both broadcast treatments containing triclopyr + fluroxypyr and the IPT treatment of triclopyr decreased dry matter yield at the first harvest, with triclopyr (IPT) being the only treatment to lower dry matter yield at the second harvest. Field studies were also conducted in 2006 and 2007 to assess sharppod morningglory control in Roundup Ready Flex® and LibertyLink® cotton systems. Herbicides evaluated included glyphosate, glufosinate, prometryn, fluometuron, and diuron. Visual ratings of percent weed control and sharppod morningglory plant counts were taken to assess control. Prometryn at 1.8 kg ai ha⁻¹ and fluometuron at 1.8 kg ai ha⁻¹ provided significant preemergence control (33-81%) of seedling sharppod morningglory. All rates of glyphosate (1.06 and 1.54 kg ai ha⁻¹) and glufosinate (0.45 and 0.6 kg ai ha⁻¹) controlled sharppod morningglory from 55 to 100% at both application timings. The addition of diuron at 1.12 kg ai ha⁻¹ to glyphosate and glufosinate at the late season application enhanced sharppod morningglory control by 3 to 16%. Additionally, in both years, no reduction in cotton yield was observed in the morningglory infested treatment when compared to the weed free treatment.

Male consumer's expectations of the fit of ready-to wear business apparel and the influence on the purchase decision

Lundie, Philne 02 1900 (has links)
Numerous authors are in agreement about apparel being a means of communication, especially in the workplace environment (Howlett et al. 2013; Li et al. 2012; Kang et al. 2011; Kwon 1994; Stuart & Fuller 1991). In fact, business apparel has been found to be used as a tool to communicate perceived meaning about the wearer to others, such as level of education, diligence, and even occupational ability (Kwon 1994; Stuart & Fuller 1991). Business apparel has the ability to be used by the wearer as a means to impress others but have also been found to produce positive feelings like confidence, productivity and dependability in the mind of the wearer (Peluchette et al. 2006). Moreover, minor changes in an outfit can influence the opinions and judgements made by others about the wearer (Howlett et al. 2015; Howlett et al. 2013). Otnes and McGrath (2001) suggest that men may attempt to achieve professional success when purchasing business apparel as the apparel worn at work may be related to achieving success in the workplace. Men are becoming more evident in the ready-to-wear apparel retail market, which may be explained by a shift in the way society sees traditional gender roles (McNeill & Douglas 2011; Otnes & McGrath 2001). In fact, Otnes and McGrath (2001) propose that men who are not limited by the view of traditional gender roles shop with motivation, often displaying shopping behaviour considered as feminine, but do so with a specific goal in mind. Increased marketing activities targeting male consumers (Seo et al. 2001), a greater variety in ready-to-wear business apparel options, due to the tendency towards a more casual dress code in many workplaces (Torres et al. 2001), and an increased consciousness about managing their own appearance (Sindicich & Black 2011) contribute to changes in the apparel purchasing behaviour of male consumers. Kang et al. (2011) suggest that men in particular expect specific outcomes, such as career advancement, communicating a positive impression to others, improving personal performance in the workplace, and feeling good about themselves, which they associate with their business apparel. Well-fitting apparel makes a positive contribution to the appearance of the wearer. Consumers, including men, often consider the fit of ready-to-wear apparel items as an aspect to consider when evaluating alternatives for purchasing. This is significant vi since the fit of apparel contributes not only to the physical comfort of the apparel item but also involves an aesthetic as well as a socio-psychological dimension (Tselepis & De Klerk 2004). Fit problems with ready-to-wear business apparel among male consumers have been reported by various authors (Sindicich & Black 2011; Sindicich 2008). However, getting a clear indication of consumers’ evaluation of apparel fit remains a complicated process (Chen 2007) and with the wide range of body shapes among apparel consumers, as well as their range of preferences towards apparel fit, problems with the fit of apparel items continue to be a topic of concern for manufacturers and retailers (Bye & LaBat 2005; Anderson et al. 2000) and the task of providing consumers with satisfactory fit is notably difficult (Ross 2005). Considering the influence which consumers’ expectations of the fit of their apparel has on the apparel purchase decision, the limited research about male consumer expectations regarding the fit of apparel is a problem worth addressing. This includes what their expectations are with regard to the fit of their business apparel, as well as factors they consider to be important when in the process of purchasing business apparel. Therefore, the overall purpose of this study was to gain knowledge regarding the functional, aesthetic and socio-psychological expectations that South African male consumers hold towards the fit of ready-to-wear business apparel, and to determine the extent to which their expectations influence their apparel purchase decisions. The study employed an exploratory, quantitative research approach. Data were collected by means of an electronic questionnaire through a combination of both purposive and snowball sampling techniques. Descriptive statistics were used to describe the demographic and psychographic profile of the sample by means of frequencies and percentage distributions and to analyse the coded data. A correlation coefficient was calculated and was used to determine the reliability of the constructs, namely the functional, aesthetic and socio-psychological expectations of fit and the importance of these apparel attributes when respondents purchase ready-to-wear business apparel. A multiple linear regression model was applied to determine the relationship between the expectations and the extent to which these influence the purchase decision regarding business apparel. vii The results of this study indicated that respondents showed a higher level of agreement with the functional expectations of the fit of their business apparel than with the aesthetic and socio-psychological expectations. However, the multiple linear regression model indicated that respondents placed greater importance on the aesthetic and socio-psychological aspects of apparel when in the process of purchasing ready-to-wear apparel for the workplace. In terms of functional expectations, respondents expected their business apparel to fit well when in their size, as well as to be comfortable and of good quality. The results further indicated that the respondents expected the fabric of ready-to-wear business apparel to be comfortable, that they like the colour of the apparel item, and that wearing the apparel item would contribute to positive feelings of self. Socio-psychological expectations included that the respondents expected ready-to-wear business apparel with good fit to make them feel fashionably dressed, give them confidence at work and also make them feel like they are a part of the company, as their business apparel should adhere to the dress code of the company. It is therefore recommended that ready-to-wear apparel manufacturers, as well as marketers and retailers, not only consider the functional aspects of apparel fit, but also focus on the aesthetic and socio-psychological aspects of apparel fit, as these also play an important role in the male consumer’s evaluation of ready-to-wear business apparel and therefore also his assessment of his own satisfaction during use. Ready-to-wear business apparel marketers and retailers can integrate male consumers’ expectations towards fit and business apparel in general into marketing strategies and as a means to retain current consumers. / College of Agriculture and Environmental Sciences / M.

Effects of the Post Multi-Fiber Agreement on Bangladesh Readymade Garments Sector

Dey, Palash-Kishore, Sumon, Md-Tawfique-Hasan January 2009 (has links)
The thesis “Effects of the Post Multi-fiber Agreement on Bangladesh Ready Made Garments Sector” is a part of our M.Sc. in Business Administration Program. The thesis paper on this topic is done under the supervision of Mr. Göran Alsén, Professor of Blekinge Institute of Technology (BTH) Ronneby, Sweden. In our country garment industry has been playing most vital role in our national economy, foreign exchange earnings, employment, growth in other sector and most prominently women employment. In the first chapter we tried to focus on the historical background of Multi Fiber Agreement, the growth of Bangladesh Garments Manufacturer and Exporter Association (BGMEA).In 1983 the total members of BGMEA were 143 with narrow export volume but in 2007 we see the total members are 4637.They contribute 75.64% of our total export (BGMEA, 2007). People who are directly involved with this sector became worried because of phase out of quota system from January 2005.But if we observe the current scenario it is very much positive for our national economy. It’s true that competition grew high but at the same time we can say that our garments industry did not lose its market reputation compared to that of other rival competitors like China, India, Sri Lanka, Vietnam etc. It’s very obvious that we have great problem with the backward linkage industry. As a result we are facing huge competition among the competitors. We have to face huge competition with the other competitors as long as we could set up our backward linkage industry. Under these circumstances, our Government is taking necessary steps to remove this problem. It is now simply a matter of time. But we hope we will get rid of this problem very soon. In this thesis paper we have tried to analyze the performance of five different RMG companies and we have also tried to examine the impact of withdrawal of quota system. Based on these five RMG factories we observe that our RMG industry is performing well after Post MFA. In addition, if we look our total exports we see that approximately 74.93% of our total export is from RMG sector. It is very promising sector compared to other export items. Thus we can say that to survive in this competitive sector our RMG sector should take some more necessary steps like improving employee efficiency, ensuring more training facility, emphasizing on backward linkage industry etc. To attract foreign investors these are very important.

Orientador: Marcelo Cristianini / Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia de Alimentos / Made available in DSpace on 2018-08-27T18:44:38Z (GMT). No. of bitstreams: 1 Oliveira_ThalesLeandroCoutinhode_D.pdf: 2386676 bytes, checksum: bc4655fa6960e3332639a4ca75c75545 (MD5) Previous issue date: 2015 / Resumo: A redução do cloreto de sódio nas formulações de alimentos processados representa um grande desafio para indústria moderna, tendo em vista a relação estabelecida entre o consumo elevado de sódio e a ocorrência da hipertensão arterial, principal fator de risco associado à ocorrência de distúrbios do cérebro e cardiovasculares. Em produtos cárneos, além de atuar sobre aspectos sensoriais e de textura, o sal desempenha papel chave sobre sua estabilidade microbiológica. Uma simples redução pode resultar em produtos instáveis durante sua vida de prateleira. Logo, para que estratégias de redução de sal sejam implementadas de maneira segura, faz-se necessário a aplicação de tecnologias ou agentes de preservação complementares. Tecnologias emergentes não-térmicas de inativação microbiana como o processamento à Alta Pressão (HPP - High Pressure Processing) surgem como opções factíveis para tal propósito, eliminando a dependência de conservantes químicos em face à redução de sal. A adição de agentes antimicrobianos naturais como barreiras adicionais à HPP (Tecnologia de Múltiplas Barreiras), visando potencializar os efeitos conservadores, têm sido apontada como uma promissora tendência na literatura moderna. Diante deste exposto, após determinação da formulação de trabalho com teor reduzido de sódio, a pesquisa objetivou ajustar as variáveis de processo "carga de pressão" e "tempo de residência" (utilizando baixas temperaturas de 25°C) para o processamento de embutido de peito peru fatiado embalado a vácuo (tipo "Blanquet"). Foram avaliadas respostas de inativação microbiana pós-processo (reduções logarítmicas) para populações inoculadas do patógeno Listeria monocytogenes e bactérias ácido láticas deterioradoras incluindo as espécies Leuconostoc mesenteroides e Lactobacillus sakei; também foram avaliados os atributos de qualidade incluindo cor, atividade de água, pH, sinerese, textura e oxidação lipídica. Em adição, visando à utilização de tecnologia de múltiplas barreiras para conservação, foi estudado o efeito da adição do componente bioativo carvacrol em concentrações de 200ppm, na formulação do produto. Empregando estratégia de simples redução, sem a adição sais substitutos, após avaliação de aspectos físico-químicos, sensoriais e microbiológicos, concluiu-se que níveis de 30% de redução de sal (cerca de 25% menos sódio) sobre o controle formulado com 20g/kg, são viáveis; entretanto, foi evidenciada redução da estabilidade microbiológica. Após avaliação de diferentes faixas de pressão e tempo de processo, seguindo os critérios exigidos de desempenho para inativação pós-processo de Listeria monocytogenes (4-5 reduções logarítmicas), um valor de 600MPa/180 segundos a 25°C se apresentou como um tratamento adequado para o produto com baixo teor de sódio estudado, promovendo reduções logarítmicas eficazes contra o patógeno-alvo estudado e a microbiota deteriorante. Alterações instrumentais (p<0.05) em alguns dos atributos de qualidade avaliados puderam ser destacadas principalmente sinerese, oxidação lipídica e textura; porém são necessários estudos mais amplos de análise sensorial. Adicionalmente, dados apresentados demonstraram que os consumidores não foram capazes de diferir o produto low-sodium processado por alta pressão isostática (600MPa/180sec/25°C) de um não pressurizado; de fato, apesar dos efeitos instrumentais significativos, estas alterações parecem não ser identificadas pelos consumidores. A adição de uma barreira natural complementar, o carvacrol, em níveis sensorialmente aceitáveis, foi capaz de potencializar os efeitos de inativação pós-processo (reduções logarítimicas) dos grupos microbianos alvo; efeitos benéficos combinados ao longo da estocagem refrigerada do produto também foram evidenciados por meio de reduzidas taxas de crescimento e fase lag aumentada, maximizando assim o potencial de conservação. A utilização combinada de HPP e carvacrol representou uma alternativa promissora contra fenômenos de injúrias sub-letais e recuperação celular. Sugere-se que a intensidade do processo HPP (em termos de carga de pressão, tempo de processo e temperatura) necessária para inativar microrganismos em níveis requeridos, possa ser reduzida na presença de barreiras antimicrobianas adicionais, garantindo a qualidade total do produto processado em condições mais amenas. Em adição, uma série de vantagens industriais podem ser destacadas tais como a redução de custos para a instalação de equipamento inicial e de manutenção (equipamentos operando em cargas mais baixas); e maximização da produção de processamento por ciclos efetivamente encurtados (ciclos de produtividade mais elevados por hora) / Abstract: The reduction of sodium chloride in processed food formulations represents a great challenge for modern industry, considering the relationship established between high sodium intake and the occurrence of arterial hypertension, the major risk factor associated with the occurrence of cardiovascular diseases and strokes. In meat products, in addition to acting on sensory quality and texture, salt plays a key role on the microbiological stability. A simple reduction can result in unstable products during their shelf-life. Therefore, for the success of salt reduction strategies implemented safely, it is necessary the application of complementary technologies or alternative preservatives. Non-thermal emerging technologies for microbial inactivation, such as High Pressure Processing (HPP), appear as feasible alternative for this purpose, eliminating the dependence of chemical preservatives considering the reduction of salt barrier. The addition of natural antimicrobial agents as additional hurdles (Multi Hurdle Technology) to the HPP, aiming to enhance the preservative effects, has been identified as a promising trend in modern literature. Given this exposed, after determination of low-sodium working formulation, this research aimed adjust the processing variables "pressure load" and "dwell time" (using low-processing temperatures of 25°C) for sliced vacuum-packaged ready-to-eat turkey breast. Post-processing microbial inactivation responses were evaluated (by logarithmic reductions) against inoculated populations of the target pathogen Listeria monocytogenes and spoilage lactic acid bacteria including Leuconostoc mesenteroides and Lactobacillus sakei; were also evaluated quality-attributes including color, water activity, pH, syneresis, texture and lipid oxidation. In addition, in order to use multiple barriers for preservation technology, was studied the effect of adding bioactive component, carvacrol at concentrations of 200ppm in the product formulation. Employing a simple reduction strategy, without adding salt substitutes, after evaluation of physicochemical aspects, sensory and microbiological, it was concluded that levels of 30% NaCl reduction (aproximatelly 25% less sodium) on the control made with 20g/kg, are viable; however, problems with microbiological stability were evidenced. After evaluation of different pressure ranges and processing time, following the performance criteria required for post-inactivation process Listeria monocytogenes (4-5 log reduction), a value of 600MPa/180 seconds at 25°C was presented with an adequate treatment for studied product with low sodium content, promoting effective logarithmic reductions against the studied target pathogen and spoilage LAB. Instrumental changes (p<0.05) in some of the evaluated quality attributes could be revealed mainly in syneresis, lipid oxidation and texture; however, a sensory confirmation needs to be established. Additionally, data presented showed that consumers have not been able to differ low-sodium products processed by HPP (600MPa/180sec/25°C) and unpressurised; in fact, despite significant instrumental effects, these changes seems to be not identified by consumers. The addition of natural barrier, such as carvacrol at acceptable sensory levels (200ppm), was able to potentiate the effects of post-process inactivation (logarithmic reductions) of the target microbial groups; combined benefit effects along the refrigerated product storage were also evidenced by reduced growth rates and increased lag phases, thus maximizing their potential for conservation. The combination of HPP and carvacrol represented a promising weapon against phenomena of sub-lethal injuries and cell recovery. It is suggested that the intensity of the HPP process (in terms of pressure load, process time and temperature) required to inactivate microorganisms in required levels, may be reduced in the presence of additional microbial barriers, ensuring the overall quality of the processed product under mild processing conditions. In addition, a number of industrial advantages can be highlighted such as reduced costs for the initial installation and maintenance equipment (low required pressure loads) and maximization of production by effectively processing cycles shortened (higher productivity cycles per hour) / Doutorado / Tecnologia de Alimentos / Doutor em Tecnologia de Alimentos
