Contudo, um dos problemas mais sérios relacionados à sua utilização diz respeito à alta susceptilibilidade da madeira ao ataque de fungos manchadores e insetos, notadamente na fase entre o corte e o processamento primário. Portanto, a adoção de medidas visando à preservação entre os lenhos juvenil e adulto é altamente necessária, garantindo uma maior durabilidade econômica na utilização desse recurso. No presente trabalho foi avaliado o efeito dos ingredientes ativos a base de Quinolinolato de Cobre – 8 e Carbendazim (T1); 2-4-6 Tribromofenol (T2); Extrato vegetal a base de Tanino (T3); Carbendazim e Prochloraz (T4), contra o ataque do fungo manchador Botryodiplodia theobromae em laboratório seguindo a norma ASTM 4445 (2003) e ingredientes ativos a base de Ciflutrina (T5) e Cipermetrina (T6), na avaliação de infestação do cupim de madeira seca Cryptotermes brevis em madeira de Hevea brasiliensis, seguindo a norma IPT – 1157 (1980) e ASTM 3345 (1990). Os resultados mostraram que os ingredientes ativos testados e avaliados isoladamente em laboratório o T1, T2, T3 e T4, não previnem na totalidade a contaminação do Botryodiplodia theobromae nos Lenhos Juvenil e Adulto da madeira de Hevea brasiliensis ao nível de 5% de significânca, e que a velocidade de penetração do fungo manchador difere nos Lenhos Juvenil e Adulto e entre as Secções Transversal, Radial e Longitudinal da madeira. De posse destes resultados, foi estabelecido um modelo que melhor se ajustou estatísticamente foi o não linear do tipo exponencial (Growth 1). Das interações avaliadas na prevenção ao ataque de cupim de madeira seca Cryptotermes brevis... / In Brazil the exploration and use of the Hevea brasiliensis Mull Arg. wood at the end of the latex production cycle from 30 to 35 years, is practically unknown. However, one of the most significant problems with its use relates to the highly susceptable wood staining fungi and insects, especially in the phase between the primary processing and cutting. The adoption of measures aimed at preserving the trunks between juvenile and adult is highly necessary, ensuring a greater durability in the economic use of this feature. The present study evaluated the effect of the active ingredients of the base Quinolinolato Copper - 8 and Carbendazim (T1); Tribromofenol 2-4-6 (T2); extract-based vegetable Tannin (T3); Carbendazim and Prochloraz (T4), against the attack of the fungus stainer Botryodiplodia theobromae standard ASTM 4445 (2003) and active ingredients the basis of Cypermethrin (T5) and Cyfluthrin (T6) in the evaluation of infestation of the dry wood termite Cryptotermes brevis wood of Hevea brasiliensis standard IPT-1157 (1980) and ASTM 3345 (1990). The results showed that the active ingredients separately tested and evaluated in the laboratory; T1, T2, T3 and T4, will not prevent the total contamination of Botryodiplodia theobromae Firewood in juvenile and adult wood of Hevea brasiliensis the 5% level of significance. The rate of the Firewood in juvenile and adult wood differ when it comes to the stainer's rate of penetration between the transverse, radial and longitudinal timber of Hevea brasiliensis as a function of time. Armed with these results, the non-linear exponential (Growth 1). Interactions evaluated in preventing the attack of dry wood termite Cryptotermes brevis, the two active ingredients the basis of Cypermethrin and Cyfluthrin demonstrated effective in the evaluation of different juvenile... ...

Previous research suggests that through engagement with Higher Education (HE), mature women students experience identity change and transformation which could lead to conflict and strain on marital relationships. The aims of this thesis are to explore the effects of identity transformation on mature women and the family unit as a whole, through a consideration of the impact of HE on family life. Qualitative methods were adopted using a narrative inquiry methodology of focused interviews, mind mapping and a student led mosaic approach to gather the data. Women with families were selected from one Foundation Degree in Early Years in a College Higher Education (CHE) environment. The views of their husbands were also gathered through interviews. This thesis argues that HE study had transformative effects on the whole family, not just the identity of the women students. Previously to HE, the women’s identity was firmly placed in the home as mothers. HE could be seen to change and reconstruct their position as a mother. These transformations and positional changes concerned family routines, relationships and parenting approaches. The women participants believed that their husbands benefitted from the secondary effects of transformation as a result of their wives’ HE studies and identity change. My thesis contributes to knowledge on this topic through the development of a model of family capital which consists of emotional, economic, cultural and social capital. Time is recognised as an important aspect of capital production and identity transformation. Husbands were viewed as reliable providers of family capital; however children who are normally viewed as consumers of family capital also became providers of capital. Through accessing capital support and having their studies valued by their family, women were able to justify their time spent on HE and minimise their feelings of guilt. This thesis is of relevance for women students and HE tutors. Using the findings of this study, HE staff can highlight the transformative effect of HE study on women students. Through raising an awareness of the importance of family capital and support networks, then HE success is more likely to be achieved.

Travel and tourism marketers face a highly competitive environment brought on by the changing demographics of the U.S. population, the most significant change being the growth in size of the mature segment of the population. In terms of market size, there are currently 73 million people age 50 and older, comprising nearly one-fourth of the U.S. population (U.S. Census Bureau 2000). That number is expected to rise to 96 million by 2010, representing one-third of the population (Rasmusson 2000). A swelling population is not the only enticement that this age group offers. It is important to note that many mature consumers have deep pockets and a strong desire to spend. In fact, they control more than three-quarters of the wealth and one-half of the discretionary income in the nation. It is also estimated that they lay claim to three-fourths of the country's financial assets and boast more than $1 trillion in annual buying power. When all is said and done, this age group accounts for 40 percent of the total consumer demand in the United States (Swartz, 1999). However, even though recognizing the significance of the mature market in terms of their market size and economic potential, little research has been conducted to identify and understand the mature travelers who use the Internet.The main purpose of this study is to profile mature travelers on the basis of Internet use. More specifically, the intention is to examine the demographic and socio-economic characteristics of mature travelers who use the Internet compared to those who do not use the Internet. In addition, the purpose of the present study is to examine whether or not differences exist between Internet users and Internet non-users among mature travelers with respect to travel behavior. Attention is paid to investigate types of trip selected, the preferred activities participated in during the travel, length of stay, travel-related expenditures, type of lodging, type of transportation, number in the travel party, and type of travel party in explaining the differences between Internet users and Internet non-users of the mature market.Data were collected by utilizing a mailed questionnaire. 433 responses (23.44 percent of the total target population) were coded and used for data analysis. Data were analyzed by employing three types of data analysis: chi-square tests of independence; t-tests; and multiple discriminant analysis.The findings in the present study suggest that there are numerous differences in demographics, socio-economic characteristics, and travel characteristics between Internet users and Internet non-users among mature travelers. As a whole, for example, the results revealed that mature travelers who use the Internet were more likely to be younger, have higher annual household incomes, and have higher levels of education than mature travelers who do not use the Internet. Also, the results indicated that mature travelers who are still working are more likely to use the Internet than those who are not working. By understanding and utilizing information gathered from Internet users' and Internet non-users' demographics, socio-economic characteristics, and travel characteristics, tourism planners and marketers can develop appropriate and effective marketing strategies that appeal to mature travelers. / Master of Science

Eukaryotic platelets are small cell fragments that are released into the bloodstream from megakaryocytes, and their production is initiated in the bone marrow. They are mainly involved in blood hemostasis and thrombus formation. The newly synthesized platelets are called reticulated platelets or young platelets. Zebrafish thrombocytes are equivalent to mammalian platelets and have similar characteristics and functions. Likewise, zebrafish has both young and mature thrombocytes. Only young thrombocytes as reticulated platelets are labeled with thiazole orange. Similarly, labeling zebrafish thrombocytes with a specific concentration of DiI-C18 showed two populations of thrombocytes (DiI+ and DiI-). Again, only young thrombocytes showed DiI+ labeling. The mechanism of selective labeling of young thrombocytes by is unknown. Furthermore, there is no zebrafish line where young and mature thrombocytes are differentially labeled with fluorescence proteins. Therefore, in this study, we identified and confirmed that the RFP labeled cells of Glofish were young thrombocytes. In addition, we found that myosin light chain 2 (MLC2) promoter is expressed in young thrombocytes. We also generated a transgenic zebrafish line, GloFli fish, where the young and mature thrombocytes are labeled with red and green fluorescence proteins respectively. Furthermore, this study showed a two-fold increase in glycerol-phospholipids (GP) in mature thrombocytes compared to young thrombocytes suggesting the lipid composition may be important for differential labeling. Therefore, we tested the liposomes prepared with different ratios of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) and observed that the lower amounts of PE favor the DiI-C18 labeling whereas higher concentrations of PC are less efficient. Also, in both PE and PC, increased concentrations of both resulted in decreased binding. These results are consistent with our observation that mature thrombocytes have higher concentrations GP and thus DiI-C18 may not bind to them efficiently compared to young thrombocytes.

The beef cattle industry has placed increased focus on mature cow size as a result of its influence on production efficiency and profitability. The objectives of this study were to evaluate relationships among lifetime measures of body weight (BW) and frame score (FS) in commercial beef females, and to assess the value of immature measures as predictors of mature cow size. Measurements of BW, hip height (HH), body condition score (BCS), and calculated FS were recorded at weaning (WN), breeding at 13 mo age (BR), and 8 subsequent periods, ceasing at approximately 5 yr of age for 232 Angus-cross females born 2004 through 2008. Correlation analysis revealed significant (P < 0.001) relationships among BW taken at WN and BR with BW measurements taken at 2.5, 3.8, and 4.8 yr of age (WN r = 0.70, 0.51, 0.61; BR r = 0.65, 0.57, 0.64, respectively). Significant relationships (P < 0.001) existed between FS collected at WN and BR, and FS at 2.5 and 3.8 yr (WN= 0.70, 0.72; BR= 0.79, 0.82, respectively). Repeatability of lifetime FS measures was 0.73. BCS was a significant (P < 0.001) source of variation in mature BW, with a unit change in BCS accounting for 41 kg BW change at 4.8 yr (P < 0.001). BW and FS were moderately to strongly related (P < 0.001) at WN, BR, 2.5, 3.8, and 4.8 yr (r = 0.62, 0.49, 0.62, 0.62, and 0.47 respectively). Prediction models for BW at 4.8 yr were similar using weaning BW alone, or with inclusion of both weaning BW and HH (R2 = 0.57 and 0.56). Similarly, breeding BW and HH were non-additive for prediction of 4.8 yr BW (R2 = 0.68, 0.58, and 0.68 for BW, HH, and BW +HH respectively). Performance at immature ages proves to be a satisfactory indicator of mature size, supporting continued incorporation of immature BW and HH and/or FS measurements into selection practices. / Master of Science

Mature female students encounter a range of challenges, including stereotype threat, which may affect their persistence in academic programs. Research has been conducted on stereotype threat in adult learners, but little research has been done on the impact of stereotype threat on mature female students in higher education. The purpose of this qualitative study using the experience sampling method (ESM) was to investigate how role conflict and social isolation due to age differences affected the learning experiences of mature female students (ages 45-54). The study used a conceptual framework incorporating Steele and Aronson’s stereotype threat theory and the concept of perceived belonging. The research questions explored participants’ use of time and interactions with others to determine the extent to which they may have experienced role conflict and social isolation due to age differences. Using ESM in conjunction with interval-contingent diaries, the study collected data on 5 mature female students enrolled at a national, for-profit undergraduate institution 5 days per week for 4 weeks. Data were analyzed, codes and categories were developed, and themes were identified according to the research questions and diary prompts. Analysis of themes suggested that participants experienced role conflict, struggled with time management, and often felt overwhelmed and exhausted. The themes also indicated that participants interacted favorably with staff and professors but found themselves in conflict with classmates, often as a result of age differences. This study may lead to the development of interventions that can be used to address the unique, diverse needs of mature female students in higher education.

Tokyo est une ville mature qui se caractérise par une contraction de sa population active à la suite du vieillissement démographique et par une stagnation de ses indicateurs économiques (Produit Urbain Brut, prix immobiliers, stagflation). Néanmoins, malgré cet état, le tissu urbain de ses espaces centraux a été rénové à un rythme soutenu à partir du tournant des années 2000. Le dynamisme de la livraison de tours de grande hauteur contraste avec le contexte de maturité. La politique de renaissance urbaine mise en place en 2002 par le gouvernement central participe de la grande mutation des espaces centraux et péri‐centraux de la capitale japonaise. Elle permet d’articuler acteurs publics et privés autour d’opérations de rénovation urbaine de grande ampleur, qui concentrent les investissements dans des espaces précis. Ce travail de recherches doctorales analyse les impacts de la maturité urbaine sur la production immobilière et les recompositions spatiales du tissu tokyoïte, en interrogeant la mutation des stratégies des acteurs publics et privés impliqués dans la fabrique urbaine. La maturité est au cœur des questionnements : qu’est ce qu’une ville « mature » ? Comment continuer de créer de la richesse dans un contexte de quasi stagnation économique et démographique ? Cette thèse de doctorat aboutit à trois constats. La ville mature évolue peu à l’échelle macro, mais connaît d’intenses recompositions internes aux échelles méso et micro, traduisant une maximisation de la concurrence et de la compétition entre acteurs et entre territoires. Fruit de cette concurrence généralisée, Tokyo se recompose en points chauds qui concentrent les investissements et en points froids sur‐déprimés dans lesquels les pertes économiques et démographiques sont importantes. Afin de maintenir des taux de rentabilité intéressants pouvant garantir les opérations de renaissance urbaine, un nouveau régime d’accumulation du capital se met en place : un régime d’accumulation « dynamique ». Ce nouveau régime maximise les profits en accélérant la rotation du capital et des investissements immobiliers par le biais d’une obsolescence accélérée du bâti et par la mise en place d’une rotation cyclique des investissements par catégorie (bureau, Résidentiel de luxe, équipement, hôtellerie de luxe). La Contrepartie en est la contraction continue des espaces économiquement rentables ou intéressants les investisseurs privés. La Ville mature entraîne alors une contraction spatiale et temporelle des investissements et aboutit à des logiques de plus en plus concentrées et de plus en plus court‐termistes. / Tokyo is a mature city characterized by two elements: its working population shrinks because of the demographic ageing, and its economic indicators stagnate (Growth Urban Product, real estate prices, stagflation). Nevertheless, in stead of this state, the urban frame of central spaces has been rapidly renewed since the turn of the 2000s. The dynamism of high rise building construction contrasts with the urban context. The urban renaissance policy initiated in 2002 by the central government encourages the great transformation of Tokyo’s central and sub‐central spaces. It allows to articulate public and private agents developing big urban renaissance projects, which concentrate investments in few urban spaces. This doctoral research work analyzes the impacts of urban maturity on real estate activities and on spatial restructurations of Tokyo’s urban frame. It investigates the strategy mutations of public and private agents involved in urban making. Maturity is the core of this PhD: What is a « mature » city? How to continue to create values in such a context of economic and demographic stagnation? This PhD thesis makes three conclusions. The mature city slightly changes at the macro scale, but faces intense internal recomposition at the meso and micro scales. It maximizes competition between agents and territories. As a result of this general competition, Tokyo is recomposed in hot spots, where are concentrated the investments, and in cold spots where economic and demographic losses are important. In order to maintain interessant rentability levels, a new capital accumulation regime appears: a « dynamic » capital accumulation regime. This new regime maximizes profits by speeding the rotation of capital and real estate investments speeding up the obsolescence of buildings and developing a cycle rotation of investments by category (commercial, residential, equipments, hotels). The counterpart is the shrinkage of economically profitable spaces. The mature city is therefore characterized by a spatial and temporal shrinkage of investments, and leads to more and more concentrated and more and more short- termist logics.

Master of Science / Food Science Institute,Human Nutrition / Valentina M. Remig / Foodborne illness is a serious health problem in the United States, and especially in the mature adult population. This research examined food safety knowledge of mature Kansans(aged 55 years and older) in three important constructs (handwashing, food handling, and food preparation), their knowledge of foodborne illness symptoms, and their food safety concerns while eating away from home. One-hundred and forty participants completed a self-administered questionnaire containing ten food safety knowledge questions representing sixty answer options. Replies to those questions were compared by age, gender, geographic location,and educational attainment. Results indicated that geographic location was statistically significantly related to food safety knowledge; however, age, gender, and education had little to moderate association. Additional findings revealed food safety knowledge was not associated with participants’ level of food safety concern while eating away from home. In conclusion, the findings revealed that mature Kansans possessed general food safety knowledge; however, some responses indicated mature adults did not fully understand certain food safety protocols. Areas identified as needing further attention included appropriate hand drying and surface cleaning, safe food and refrigerator temperatures, proper thawing practices, as well as safe leftover and melon preparation.

Companies are dependent on continuously provide the market with new products to keep its market position and profitability level. The companies examined in this thesis are two bigger Swedish enterprises that have a long history in a mature business-to-business context providing industrial goods to the market. This work examines how users are involved in the different innovation and product development activities. The problem is to understand how business-to-business companies co-operate with stakeholder and users, when in the product life cycle that is done, and who are the ones doing the actual innovation. The methodological approach for the work was deductive, building a theory including innovation, strategy and user theories that was empirically tested and followed by an analysis and conclusion of the found evidence. Key findings: Most if not all innovations in mature market are routine ones. There is lack of strategic focus due to micromanagement that shifts focus rapidly. Innovations are often found in the beginning and in the end of the product life cycle. Mature markets tend to utilize a more closed innovation model as opposite to an open model. Users are not heavily involved in the actual innovation process. Stickiness and tacit knowledge is quite big in large corporation event though there is said to be a strategic focus on the customers. Implications: More involvement of users, especially lead users, will lead to more innovations. Utilising strategic buckets of different sizes for spreading the resources on different innovation types (routine/disruptive/discontinuous) to become successful
