Texte intégralRésumé :
Reproduction is costly and involves a number of sequential physiological processes that require different levels of energetic investment. In mammalian species gestation and lactation require the most energy and the amount of energy invested in reproduction is reflected in litter size at birth and by offspring growth through weaning. The object of this study was to describe variation in Weddell seal (Leptonychotes weddellii) pup mass at birth and during several ages of the lactation/nursing period, and to evaluate the ability of several maternal traits to explain this variation. Mass measurements were collected from 887 pups at parturition and throughout lactation in Erebus Bay, Antarctica during the 2004 through 2010 field seasons and maternal traits were taken from a long term database. Analysis demonstrated high individual variation in pup mass within a season and modest variation among seasons which suggests that pup mass may be correlated with individual animal attributes rather than annual variation in environmental conditions. Maternal age, a female's reproductive status the previous season and their interaction were found to be the most influential maternal traits. Pup body mass at parturition and during lactation showed maternal age-related variation with evidence of senescence during pre-partum investment and terminal investment during post-partum investment. A female's reproductive status in one season affected her reproductive investment during lactation in consecutive seasons but that effect was correlated with age. Younger females who pupped in consecutive seasons weaned larger pups than those females who were of the same age and did not give birth in consecutive seasons. The opposite was found to be true for older females. The variation in the affect of maternal traits on maternal investment may be due to the increased energy requirement of lactation, age specific changes in reproductive costs, and a senescent decline in physiological function.

Renard, Julie. « La médiation du manga en France : un lent processus de légitimation ». Thesis, Toulouse 2, 2011. http://www.theses.fr/2011TOU20123.
Texte intégralRésumé :
L’engouement pour les œuvres d’origine japonaise sur le territoire français est à l’origine de notre questionnement de départ. Cette recherche en Sciences de l’Information et de la Communication propose d'étudier le processus de légitimation et de médiation du manga en France. Dans leur pays d’origine, les mangas sont issus de techniques picturales et graphiques ancestrales mais ne prennent véritablement leur forme contemporaine qu’au lendemain de la Seconde Guerre mondiale, grâce à un mangaka : Osamu Tezuka. S’ils sont parfaitement intégrés dans les pratiques culturelles japonaises, la situation est tout autre dans notre pays. Ainsi, nous nous proposons de revenir sur la construction du processus de légitimation du manga en France par l’étude du discours d’un corpus de deux titres de presse. L’approche diachronique nous permet de revenir sur les différentes étapes de l’introduction des mangas depuis l’arrivée de l’un des premiers dessins animés à la télévision hertzienne en 1978 : Goldorak. C’est ensuite aux lecteurs que nous donnons la parole grâce à une étude qualitative des pratiques. L’enquête de réception nous donne alors les moyens de mieux comprendre la diversité des pratiques, le processus de construction de sens opéré par les lecteurs et l’appropriation de l’objet au fil du temps. Loin de la représentation d’un lecteur enfermé sur lui-même, notre recherche témoigne de la diversité d’engagement et des modes de faire des lecteurs et de l’importance de la dimension sociale qui accompagne la lecture. Un regard qui met en lumière les mécanismes de médiation du manga tant sur un plan intime que socialThe keen interest in Japanese works in France triggered our questioning. Through this research in science of information and communication, we propose to study the process of legitimization and mediation of the manga in France. In their country of origin, mangas come from remote pictorial and graphic techniques, but only take their current form after World War II, thanks to one mangaka: Osamu Tezuka. Even though mangas are perfectly integrated in Japanese culture, the situation is quite different in our country. Thus, we will come back on the building of the process of legitimization of the manga in France through a study of the publications from two selected periodicals. The diachronic approach enables us to come back on the different steps of the manga introduction in France, since the arrival of one of the first cartoons on television in 1978: Goldorak. We will then put the emphasis on the readers’ practises, through a qualitative study. The reception survey gives us a better understanding of the diversity of the practices, the process of constructing meaning by the readers, and how they made manga their own over time. Far from the representation of a withdrawn reader, our study demonstrates that there is diversity in the involvement and practices of the readers, as well as a social dimension associated to the reading. This approach highlights the mechanisms of manga mediation, from a personal as well as from a social point of view

A mangueira (Mangifera indica) é uma frutífera de importância comercial no Brasil e no mundo. É cultivada em diversas regiões, incluindo o semiárido e árido irrigados, tais como no Vale do São Francisco, no Brasil, e países como Omã e Paquistão. Nesses locais o déficit hídrico é considerado um dos principais fatores que limitam o desenvolvimento vegetal. Além disso, a murcha-de-ceratocystis, causada por Ceratocystis fimbriata, é uma das principais doenças da mangicultura do Brasil e em Omã e Paquistão. Não há fungicidas eficientes, sendo o método de controle mais eficiente é o uso de variedades resistentes. Levanta-se a hipótese de que o déficit hídrico possa causar da predisposição de infecção de C. fimbriata em variedades de mangueira resistentes. No entanto, até o momento não há estudos sobre a interação entre C. fimbriata e mangueiras submetidas a déficit hídrico. O objetivo deste estudo foi avaliar o efeito do déficit hídrico na incidência e severidade da doença em variedades de mangueiras consideradas resistente à C. fimbriata. Para isso, três variedades de mangueira, „Ubá‟, „Dura‟ e „Manila‟, foram avaliadas quanto à resistência em diferentes condições de déficit hídrico. As mudas de mangueira conduzidas em vaso com substrato comercial a base de pinus foram submetidas a quatro níveis de déficit hídrico e inoculadas com C. fimbriata (CEBS15). Plantas não inoculadas e submetidas aos mesmos regimes hídricos serviram de testemunha. As mudas das variedades „Ubá‟ e „Dura‟ foram conduzidas na mesma época, enquanto que „Manila‟ foi conduzida posteriormente. Cada vaso contendo uma planta foi considerado como uma unidade experimental. Os vasos foram preenchidos com a mesma quantidade (6,8 kg) de substrato. Avaliou-se a mortalidade de mudas mortas, número médio de dias da inoculação até a morte das plantas; potencial hídrico foliar (Ψw), diâmetro de caule (DC), comprimentos das lesões no sentido longitudinal ao caule, área da lesão no sentido radial do caule, severidades das lesões nos sentidos longitudinal e radial, trocas gasosas e na „Manila‟ também se avaliou a fluorescência da clorofila a. Os resultados foram submetidos à análise estatística descritiva. Não houve morte de plantas não inoculadas. A mortalidade foi baixa na „Ubá‟ e alta na „Dura‟, mesmo em condições consideradas sem déficit hídrico. Já na „Manila‟ a viii mortalidade foi alta em déficit hídrico severo apresentando o maior número de dias entre a inoculação e morte. De forma geral, a „Ubá‟ apresentou os menores valores de severidade e comprimento de lesão, sendo que o déficit hídrico influenciou no aumento da lesão. A „Dura‟ apresentou maior severidade e comprimento de lesão, não influenciados pelo nível de déficit hídrico. A „Manila‟ apresentou a maior severidade e o maior comprimento de lesão em 15% da Cp. Houve redução do Ψw e DC das plantas que morreram. As trocas gasosas foram comprometidas nas plantas inoculadas, principalmente nas plantas mantidas sob déficit hídrico severo. Os valores das variáveis de fluorescência da clorofila a apresentaram reduções severas em plantas da variedade „Manila‟ inoculadas e mantidas a 15% da Cp. Concluiu-se que a variedade „Ubá‟ permaneceu resistente, mesmo em condições de déficit hídrico; a „Dura‟ não foi resistente ao isolado CEBS15, mesmo em condições ótimas de irrigação; e a „Manila‟ foi suscetível em condições de déficit hídrico severo.
The mango tree (Mangifera indica) is a fruitful of commercial importance in Brazil and worldwide. It is cultivated in several regions, including the semi-arid and arid irrigated, as São Francisco Valley in Brazil, and countries like Pakistan and Oman. In these places the water deficit is considered one of the main factors that limit plant growth. Moreover, Ceratocystis wilt, caused by Ceratocystis fimbriata, is a major disease of mango in Brazil and Oman and Pakistan. There are no effective fungicides, and then the most efficient method of control is the use of resistant varieties. Raises the hypothesis that water deficit may cause predisposition to infection of C. fimbriata on varieties of mango trees resistant. However, until now there are no studies on the interaction between C. fimbriata and mango trees exposed to water deficit. The aim of this study was to evaluate the effect of drought on the incidence and severity of disease in mango varieties considered resistant C. fimbriata. For this, three varieties of mango, 'Ubá', 'Dura' and 'Manila', were evaluated for resistance in different conditions of water deficit. Seedlings potted mango conducted with commercial substrate base pine were treated with four levels of water deficit and inoculated with C. fimbriata (CEBS15). Plants not inoculated and subjected to the same water regimes served as witness. The seedlings of the varieties 'Ubá' and 'Dura' were conducted at the same time, while 'Manila' was conducted later. Each pot contains a plant and was regarded as an experimental unit. The pots were filled with the same amount (6.8 kg) of substrate. Were evaluated the mortality, average number of days from inoculation to death of plants, leaf water potential (Ψw), trunk diameter (DC), lengths of lesions in the longitudinal direction to the stem, the lesion area in the radial direction of the stem, severity of lesions in longitudinal and radial directions, gas exchange and in the 'Manila' also evaluating the fluorescence of chlorophyll a. The results were submitted to descriptive statistical analysis. No deaths of non-inoculated plants. The mortality was low in 'Ubá' and high in 'Dura', even in conditions considered without water deficit. In the 'Manila' mortality was high in severe water deficit presenting the highest number of days between inoculation and death. In general, the 'Ubá' showed the lowest values of severity and lesion length, and water deficit influenced the increase in lesion size. x The 'Dura' showed greater severity and length of lesion and were not influenced by the level of water deficit. The 'Manila' had the highest severity and lesion length at 15% of Cp. Decreased in the Ψw and DC of plants that died. Gas exchanges were compromised in the inoculated plants, especially in plants grown under severe drought. The parameters of chlorophyll a fluorescence showed severe reductions in inoculated plants of the variety 'Manila' and maintained at 15% of Cp. It was concluded that the variety 'Ubá' remained resilient, even in conditions of water deficit; the 'Dura' was not resistant to the isolated CEBS15, even under optimal irrigation conditions; and the 'Manila' was susceptible in severe water deficit conditions.

Texte intégralRésumé :
La thèse analyse les relations entre la bande dessinée japonaise (le manga) et le pouvoir dans le Japon contemporain (de 1960 à nos jours). Le but est de retracer, d’un point de vue d’Histoire culturelle, l’évolution des discours politiques contenus dans les mangas de cette période et leurs évolutions dans le temps, en les confrontant avec la situation de ce médium populaire qui est l’objet d’un double mouvement de reconnaissance et de censure de la part des institutions japonaises. La première partie s’attache à définir les spécificités du gekiga, un genre de manga plus adulte apparu au début des années 1960 qui adhère en partie aux discours contestataires de l’époque. La partie suivante (les années 1970 principalement) marquent une rupture avec la précédente à travers le rejet des idéologies politiques. Par la suite, dans les années 1980, le statut du manga change progressivement : il commence à devenir un médium « normal », parfois même pédagogique, alors qu’il était jusque là critiqué pour sa mauvaise influence sur la jeunesse. Cette normalisation va aussi de pair avec une « nationalisation » du manga, du moins dans ses thèmes. Enfin, du milieu des années 1990 à nos jours, la nationalisation devient quasiment une réalité politique avec les mesures prises par les pouvoirs publics pour faire du manga un patrimoine national et un soft power utilisable par la diplomatie japonaise. Néanmoins, ces politiques ont des limites et se heurtent à un médium difficilement domptable par le pouvoir car profondément subversif. De surcroit, les discours de certains mangas dans les années 2000 se radicalisent, et ce dans plusieurs directions politiques : le nationalisme et la critique socialeThe present dissertation analyses the relationship between Japanese comics (manga) and power in contemporary Japan (from 1960 to present). Its aim is to trace back, from a cultural history point of view, the evolution of political discourses within the manga from this period and their changes over time, and to analyze them against the background of manga as a popular medium both recognized and censored by Japanese institutions. The first chapter seeks to define the specifics of gekiga, a more adult genre of manga which emerged in the early 1960s and mostly endorsed the political protest discourses of the time. The next part (mainly the 1970s) marked a break with the previous period through the rejection of political ideologies. Subsequently, in the 1980s, the status of manga changed gradually: it started to become a “conventional” medium, sometimes even educational, whereas it had previously been criticized for its bad influence on youth. Such a normalizing process is also associated with a “nationalization” of manga, at least in its themes. Finally, from mid 1990 to our days, the nationalization becomes almost a political reality including measures taken by the various governments to turn manga into a national heritage and a soft power to be used by diplomacy. Nevertheless, these policies are reaching their limits insofar as they have to deal with a profoundly subversive and hard-to-tame medium. The discourse of some manga has become more radical in the first decade of the 21th century but it tends to follow two different political orientations: nationalism and social criticism

Texte intégralRésumé :
In a novel approach using agency theory, we conceptualize export pricing as price manipulations an exporter initiates to cope with the distributor-level, internal competition with the other product lines the distributor carries. We argue that suppliers can influence foreign resellers' behaviors and therefore manage export channel relationships with prices. Using a sample of 283 exporter-importer relationships, we uncover the export price manipulations used to cope with internal competition, and we examine their impact on the exporter economic performance. We show that the performance effect of this pricing policy is achieved through the adequate role performance of the importer. Moreover, using a small but rare dyadic data set, we offer an additional test of the effectiveness of this form of pricing. Finally, by comparing the results of our study to exporters' practice we show how they tend to overuse price discounts to motivate their overseas distributors. (authors' abstract)

Includes bibliographical references (p. 64-65).
The research conducted for this thesis was performed at "Company X", a U.S.-based engineered goods manufacturer. This project focused on the company's Advanced Manufacturing group and its process technology development methodology. The newly founded Advanced Manufacturing group started multiple innovation projects, but did not successfully implement any of them so far. Lack of organizational integration, an overall R&D strategy, as well as a defined innovation methodology negatively affected the difficult situation of that small group of engineers. This project seeks to compare the innovation methodology and process technology development of Advanced Manufacturing with best practices from similar industries as well as literature. An analysis of how to choose the right R&D projects, as well as how to execute these projects, demonstrates the differences between Company X and other organizations that are considered innovative. Case studies of a specific R&D project, in addition to an interdisciplinary workgroup of Advanced Manufacturing, highlight the positive and negative characteristics of the current innovation process. The results of this analysis provide Company X with additional insights how to use the existing innovation resources more successfully. Recommendations provided in this thesis can be used by Company X to support future technology development projects but also to help the newly founded task force that started to develop a company-wide innovation strategy (process and product innovation). Keywords: Product Development, Process Development, Advanced Manufacturing, Innovation.

Kanee, Emmanuel Lah. « Strategies to Manage Transfer Pricing Risks ». ScholarWorks, 2019. https://scholarworks.waldenu.edu/dissertations/7812.
Texte intégralRésumé :
Transfer pricing compliance related issues continue to pose challenges to leaders of multinational entities (MNEs) and tax regulators. MNE leaders strive to mitigate the risks of non-compliance violations and double taxation, while tax regulators seek to minimize profit shifting and revenue losses. This multiple case study explored strategies for managing transfer pricing risks against the backdrop of various risks MNE leaders face for non-compliance violations. The cost contribution agreement theory served as the conceptual framework for this study. Data were collected from organizational documents and semistructured interviews conducted with 6 finance executives representing 2 multinational entities in the midwest and southwest regions of the United States who have implemented successful strategies to manage transfer pricing risks. Data were analyzed using Yin's multiple-step thematic analysis process. Following the thematic data analysis 5 themes emerged, including commitment to tax compliance, tax minimization, advance pricing agreement (APA), comparable uncontrolled price method (CUP), and cost plus method (CPM). MNE leaders favor commitment to tax compliance as an effective strategy as penalties for non-compliance increases risks to business functionality. The findings of this study may help business leaders to follow compliance procedures and adopt risk mitigation strategies, while also informing regulators to update tax regulations to reflect current economic realities. The findings of this study could result in positive social change through an enhanced governmental revenue that stimulates economic growth, improves productivity, and promotes technological innovations.

Para isso foram utilizados banhos térmicos com diferentes tempos e temperaturas (46o C, 70 min e 52 oC, 5 min), e diferentes doses de radiação gama (doses 0,3 e 0,75 kGy) em mangas Tommy Atkins procedentes da região de Petrolina. As mangas tratadas pelo método combinado foram armazenadas em temperaturas idênticas à do processo de transporte e estocagem comercial (11º C por 14 dias e temperatura ambiente 25º C por 12 dias), simulando as condições reais a que são submetidas ao serem exportadas. As frutas foram avaliadas através de análises físico-químicas para serem determinados os parâmetros mais adequados de tratamento. Conforme previsto por Oliveira (1998) o método combinado de irradiação e tratamento hidrotérmico apresentou resultados superiores aos métodos individuais no aumento da vida de prateleira.In this research the effect of the hydrothermal treatment and irradiation as a combined method of food conservation and disinfestations was studied, searching to optimize the impact over the final product desired characteristics. Tommy Atkins mangoes from Brazil were submitted to a combined treatment: thermal treatment (46o C, 70 min and 52 oC, 5 min) and gamma irradiation treatment (doses 0,3 and 0,75 kGy). The fruits were stored at 11oC during 14 days and kept at an environmental condition for more 12 days, where their physicalchemical and sensorial properties were evaluated. As predicted by Oliveira (1998) the combined method of irradiation and thermal treatment showed better results then the individual methods in increasing the shelf-life.

Texte intégralRésumé :
When performing an organizational change, it is important to be aware of the culture within the company. The organization at Saab Aerosystems has a huge technical focus, which can of course be beneficial when awakening interest for a change. Another characteristic of Saab Aerosystems is that its employees are interested in being involved in change processes and have the ability to influence such changes. It is therefore important that the leader of a proposed change has a good relationship with the employees and excellent communication skills in order to both inform and listen to them. It is also important to create a commitment to change if a change project is to be successful. Within Saab Aerosystems this commitment can be created by engaging informal leaders within the project team. These employees often have a big influence on the organization as well as good knowledge of the technology and their departments’ operations. It is also important to give the organization’s members time to think through and accept a change. Without this time, resistance towards a change project can otherwise be created due to lack of understanding for the change. To create commitment to a change, the employees must also feel that they can manage the change and the situation that comes after the change. It is therefore important that the organization’s employees receive the necessary tools and education in order to give them confidence and motivation to carry out, and be a part of, the change project.
A difficult aspect during a change project can be to anchor the change within the organization. At Saab Aerosystems, changes can be anchored by involving representatives from upper management in change projects. These persons must in their turn request work that has been achieved according to the results of the change and even more importantly ensure that the change is used even upon completion of the change project. Making these demands can motivate the line managers and other employees to work according to the change and prevent reverting to old work methods and models. Finally, it is important to measure the change project progress. Examples of measure variables that can be used are business cases, questionnaires and lessons learned. These general variables ought to be complemented by specific variables for the actual change.

Texte intégralRésumé :
In February 1995, the Australian Federal Government Industry Task Force on Leadership and Management, released Enterprising nation: Renewing Australias managers to meet the challenges of the Asia-Pacific century, 1 (known as the Karpin Report). The Karpin Report defined 1995 - 2010 as a developmental period for improving Australian business practices at leader and manager level. It identified five levers for change. Australian businesses were encouraged to focus on globalisation. Life long learning was seen as a key ingredient in up skilling workers and managers for evolving work environments. Australia was advised to build an enterprise-focused culture. Managers and leaders were encouraged to value diversity in the workforce. Enterprises and education and training institutions were encouraged to implement best practice procedures.
This study situated the Karpin recommendations in the literature on gender, leadership, management, and Australian social, economic and political conditions. Employing an interdisciplinary approach and using quantitative and qualitative methods, it sought the views of women in senior, middle and frontline or supervisory positions, in large, medium and small businesses.
The study concluded that, in terms of creating diversity within institutionalised leadership, recruitment practices and social circumstances still encouraged the status quo. It found that refocusing Australian business and its leaders was unlikely to provide expanded opportunities for women in leading and managing. The skills women were acknowledged to have often aligned with skills sought for lower management positions. This has been one contributing factor in confining women to lower decision-making roles except in some education and community service environments. In these areas where women often form the majority of workers and reflect the cultures of their industries very successfully, more women occupy senior positions. The study found that womens skills were comprehensive and suited to roles carrying greater responsibilities. It also discovered that not all of the existing approaches to preparing women to lead and manage served women well; however, some effective strategies were in place. It concluded that for women to be appointed to positions of high responsibility, they should successfully reflect a recognisable management approach, congruent with the companys and industrys current style and values. This tended to perpetuate existing practices of competitive individualism and self-interest.
Since the 1980s, managers have been disproportionately elevated in status, with accompanying high salaries and bonuses. There is a risk that leaders will be credited with more wisdom and vision than warranted. Australia leaders need to have a mix of vision and business acumen. While many women managers have this mix and are prepared to be leaders, they may not be appropriately connected to the senior recruitment market. As a subtext, complex levels of vested interests, ties of loyalty and forms of reciprocity often operate in the appointment of senior personnel. Women tend to operate outside these practices and may be reluctant to endorse them. This may partially account for the unchanged circumstances of a small number of women in top senior positions.
The study concluded that the current level of refocusing of Australian businesses was resistant to change and limited in responding to expertise in the marketplace. The challenge of globalisation requires decision-makers with specific skills, knowledge and experiences. It requires people who will act with morality and preferred futures in mind rather than quick returns and advanced levels of self-interest. For organisations keen to identify these kinds of leaders then selection processes will need to differ in order to be highly attuned to recruiting individuals who can help build a responsive, innovative and caring society.

Roth, Steffen. « How Many Networks Are We to Manage ? » Universitätsbibliothek Chemnitz, 2007. http://nbn-resolving.de/urn:nbn:de:swb:ch1-200700161.
Texte intégralRésumé :
The continuous transformation of the industrial society into a service and knowledge society is accompanied by profound change of demand: Customer requests will increasingly focus on individual products, shorter delivery times and appropriate prices. To encounter these challenges under the conditions of dynamic global markets and inter-regional competition, the CRC 457 “Non-Hierarchical Regional Production-Networks” at the Chemnitz University of Technology focuses on SME and investigates ways to implement customer-oriented, temporary networking of smallest, autonomous units (“competence cells”) in the region of South-West-Saxony.
As a partial result of this research we are able to present a model of competence cell based networking distinguishing between three levels of networking, each with its own logic of reproduction (cp. Figure 1):
1) According to a most general concept, networks can be seen as given in any social context. Regarding a specific region, one has to assume that there is a broad array of infra-structural, mental and communicative relations; that as a whole we call the Regional Network. This level can be seen as basic level of competence cell based networking, specific elements (competence cells) of this network can be seen as necessary resources of the following level.
2) The second level of networking we call Competence Network. The first continuous problem of this network is to select competence cells according to relevant parameters that may be defined by customer orders or, in view of new market entry, be generated by the Competence Network itself. The second problem is to arrange these cells along a product specific value chain and, by this means, to create temporary production networks. Concerning both of the problems, the third is to find a non-hierarchical mode of negotiation.
3) On the third level temporary alliances of basically autonomous competence cells can be observed. After executing their order, these Production Networks dissolve and the constituent cells reenter the second or even the first level of networking.
Generalising our observation we now assume that every phenomena labelled as regional or industrial network or district should be investigated in view of (these) different levels of networking, especially if we are interested in dealing more efficiently with the problems of network management. Hence, we suggest to first answer the question “Which (of these) networks are we to manage?” before asking how.
Concerning the latter, a synopsis on the discourse on managing networks shows three major approaches:
1) Networks are assumed to be uncontrollable (cp. e.g. Castells 2001), as they are self-organised systems selecting external control impulses only by their own criterias of relevance, so we have either to adapt the logic of the target system (which implies self-adaption) or to take the risk of being totally ignored. With this in mind we can’t speak of control in terms of causal logic.
2) Networks are assumed to be cultivable: According to Wenger and Snyder (2000) for example networks are uncontrollable, but - like a gardener - we are able to set adequate general conditions for their “growth” and continuity.
3) Networks are assumed to be controllable: For authors like Sydow (2000) networks are to be seen as hybrid forms of coordination recombining aspects of market and hierarchy. Thus, recombining the classical means of control will finally lead to the ability to manage networks.
It will be to show that each of these approaches focuses on specific aspects of networking, thus, each of them is creating a self-contained concept of networks: Castells refers to networks as a basal nexus of (global) interconnectedness that, like the Regional Network in our case, obviously can’t be managed. Wenger and Snyder are interested in network-organisations that (like Competence Networks) also can’t be controlled but can be implemented by and embedded in other social systems (cp. Grabher 1993). Sydow finally observes networks of more or less autonomous organisations corresponding to our Production Networks, which are in deed more or less controllable.
Not least because of their different theoretical assumptions, all these concepts seemed to be not only incommensurable but incompatible so far. Nonetheless, during our work in CRC 457 we were to manage all these concepts while approaching to one single objective of research. Therefore, we had to ask, how many perspectives on network are we to manage? The answer is: at least three. Integrating these, we generated a holistic life-cycle model of network, which we like to present as starting point for further research in the field network management.

In February 1995, the Australian Federal Government Industry Task Force on Leadership and Management, released Enterprising nation: Renewing Australia's managers to meet the challenges of the Asia-Pacific century, 1 (known as the Karpin Report).

Texte intégralRésumé :
Information technology (IT) managers worldwide have adopted cloud computing because of its potential to improve reliability, scalability, security, business agility, and cost savings; however, the rapid adoption of cloud computing has created challenges for IT managers, who have reported an estimated 30% wastage of cloud resources. The purpose of this single case study was to explore successful strategies and processes for managing infrastructure operations costs in cloud computing. The sociotechnical systems (STS) approach was the conceptual framework for the study. Semistructured interviews were conducted with 6 IT managers directly involved in cloud cost management. The data were analyzed using a qualitative data-analysis software to identify initial categories and emerging themes, which were refined in alignment with the STS framework. The key themes from the analysis indicated that successful cloud cost management began with assessing the current environment and architecting applications and systems to fit cloud services, using tools for monitoring and reporting, and actively managing costs in alignment with medium- and long-term goals. Findings also indicated that social considerations such as fostering collaboration among all stakeholders, employee training, and skills development were critical for success. The implications for positive social change that derive from effectively managing operational costs include improved financial posture, job stability, and environmental sustainability.

Texte intégralRésumé :
Since 2005, most midsize company information technology (IT) projects had a 62.4% failure rate because of wrong project team communication skills or cost overruns. IT leaders expect negative IT project outcomes will cost over $2 billion by 2020. Using the actor-network theory, the purpose of this single case study was to explore strategies used by IT leaders from a midsize IT company in Washington, D.C. to plan and execute projects under budget and on time. Using purposeful sampling, 5 IT leaders were selected for this study because of their experience in implementing successful strategies for projects. Data were collected using face-to-face semistructured interviews, company documentation, and internal organizational risk reports. Yin's 5-step process was used for data analysis to compile, disassemble, reassemble, interpret, and conclude the data. The interpretation of data, subjected to methodological triangulation and member checking to strengthen the dependability and credibility of the findings, yielded 3 themes of IT leader communication skills: IT leader strategy, IT leader knowledge, and implementation of cost savings. The findings indicated that IT leaders serve as the key actors in the IT project network, and leader communication skills are essential for implementing strategies for IT project completion and cost savings. With this knowledge, IT leaders can implement strategies to plan and execute projects under budget and on time. The implications for a positive social change includes the potential for IT leaders to reduce project production waste and contribute to economic expansion.

Almuhimedi, Hazim. « Helping Smartphone Users Manage their Privacy through Nudges ». Research Showcase @ CMU, 2017. http://repository.cmu.edu/dissertations/1103.
Texte intégralRésumé :
The two major smartphone platforms (Android and iOS) have more than two mil- lion mobile applications (apps) available from their respective app stores, and each store has seen more than 50 billion apps downloaded. Although apps provide desired functionality by accessing users’ personal information, they also access personal information for other purposes (e.g., advertising or profiling) that users may or may not desire. Users can exercise control over how apps access their personal information through permission managers. However, a permission manager alone might not be sufficient to help users manage their app privacy because: (1) privacy is typically a secondary task and thus users might not be motivated enough to take advantage of the permission manager’s functionality, and (2) even when using the permission manager, users often make suboptimal privacy decisions due to hurdles in decision making such as incomplete information, bounded rationality, and cognitive and behavioral biases. To address these two challenges, the theoretical framework of this dissertation is the concept of nudges: “soft paternalistic” behavioral interventions that do not restrict choice but account for decision making hurdles. Specifically, I designed app privacy nudges that primarily address the incomplete information hurdle. The nudges aim to help users make better privacy decisions by (1) increasing users’ awareness of privacy risks associated with apps, and (2) temporarily making privacy the primary task to motivate users to review and adjust their app settings. I evaluated app privacy nudges in three user studies. All three studies showed that app privacy nudges are indeed a promising approach to help users manage their privacy. App privacy nudges increased users’ awareness of privacy risks associated with apps on their phones, switched users’ attention to privacy management, and motivated users to review their app privacy settings. Additionally, the second study suggested that not all app privacy nudge contents equally help users manage their privacy. Rather, more effective nudge contents informed users of: (1) contexts in which their personal information has been accessed, (2) purposes for apps’ accessing their personal information, and (3) potential implications of secondary usage of users’ personal information. The third study showed that user engagement with nudges decreases as users receive repeated nudges. Nonetheless, the results of the third experiment also showed that users are more likely to engage with repeated nudges (1) if users have engaged with previous nudges, (2) if repeated nudges contain new in- formation (e.g., additional apps, not shown in earlier nudges, that accessed sensitive resources), or (3) if the nudge contents of repeated nudges resonate with users. The results of this dissertation suggest that mobile operating system providers should enrich their systems with app privacy nudges to assist users in managing their privacy. Additionally, the lessons learned in this dissertation may inform designing privacy nudges in emerging areas such as the Internet of Things.

Texte intégralRésumé :
This research uses the inventory of 3 actively managed forest estates located in the Coast, Southern Interior, and Northern Interior forest regions in British Columbia. The performance of two groups of forest management strategies (harvest reduction and increased growth rate strategies) is explored in order to determine the carbon storage potential. A sensitivity analysis is conducted for the strategy that reduces the harvest to a fixed target level to determine the cost to produce carbon credits. A new method is developed to reduce the cost to produce carbon credits through implementing fluctuating harvest schedules that allow the target harvest to fluctuate between a minimum accepted level and the baseline level.
The results confirmed that at forest estate level, harvest reduction strategies outperform by a significant margin the increased growth rate strategies. There were no differences in terms of carbon storage and age class distribution between the various harvest reduction strategies analyzed in this study (fixed target harvest level, increased minimum harvest ages, and 2 strategies to increase area in reserves). Thus, the strategy that reduces the harvest to a fixed target level is preferred because it provides more flexibility in addressing natural disturbances and market fluctuations. The cost to produce carbon credits ranged from $3.9 to $40.8 tCO₂e-¹ (at 0% discount rate), out of which, the opportunity cost of reducing harvest represented 58%-97%. It was demonstrated that the inclusion of the opportunity cost of reducing harvest dominated the cost to produce carbon credits which, contrary to previous findings, increased with increasing forest productivity expressed both, as site index (i.e., top height in m at age 50) and average value of harvested timber (in $ ha-¹). The new method that implements fluctuating harvest schedules reduced the cost to produce carbon credits by up to 17% (at 0% discount rate).Forestry, Faculty of

Cocconcelli, L. « Manage speculation risks in the dry bulk industry ». Thesis, University College London (University of London), 2017. http://discovery.ucl.ac.uk/1559983/.
Texte intégralRésumé :
The peak to through phase in the dry bulk shipping market between 2005 and 2010 is the rational background of this thesis. The concomitant speculative events unfolding on commodity markets raise the question of whether or not dry bulk shipping market is exposed to speculation, if these speculative behaviours can be transmitted to the dry bulk industry from other connected markets (i.e. commodities) and if this speculation influences investment decisions of ship-owners and the sustainable growth of port cities. Against this backdrop, this thesis represents a novelty and fosters the debate regarding the negative effects of speculation in the dry bulk industry. Additionally, it provides a comprehensive analysis of the key drivers of boom and bust cycles in the dry bulk industry and provides a conceptual framework to manage speculative risks. Given these objectives, first, this research demonstrates that the super cycle between 2005 and 2010 witnessed in the dry bulk industry was driven by speculative behaviours. Secondly, it proves that the dry bulk speculative cycle was related to recent speculative trends in commodities. Thirdly, the research shows how freight rates, commodity prices and port infrastructure influence each other and how speculation spreads to other important ship-owners' investment areas. Fourthly, it demonstrates that maritime speculation can be transmitted from port activities to the regional real estate market. The findings emphasise that speculation modifies the investment decisions in the dry bulk shipping market. Additionally, the final results prove that dry bulk is affected by periods of boom and bust cycles leaving the entire industry prone to instability and excessive investment exuberance. Ultimately, the thesis contributes in the understanding of boom and bust periods to effectively manage speculative risks in the dry bulk industry.

Texte intégralRésumé :
Persons who pose threats of violence can be rich sources of information for professionals charged with ensuring safety and security. The interviewing of threateners is thus considered important among such professionals, but research on the topic is scarce. This thesis seeks to advance current knowledge by proposing a scientific perspective on effective threat assessment and management (TAM) interviewing. What are the expected dynamics when interacting with persons who threaten to cause harm and, given these dynamics, which interview methods work best? A novel experimental paradigm was developed and employed in Studies I, II, and III. Participants were given a fictitious case describing two conflicting parties and were then asked to take on the role of the threatening party in a subsequent interview with the conflicting party. Study I (N = 157) examined whether individuals’ intent to actualise a threat becomes evident in how they verbalise that threat. Intent was manipulated across three conditions through the likelihood to actualise the threat: low likelihood (no intent: bluffers), medium likelihood (weak intent: conditional actualisers), and high likelihood (strong intent: decisive actualisers). Based on theory and research in cognitive psychology, it was predicted that decisive actualisers would provide the most detail about the implementation of the threat, followed by conditional actualisers, and bluffers would provide the least. The opposite trend was found: Persons more likely to actualise a threat were found to be less informative about its implementation. Study II (N = 179) tested the effect of two interview techniques (low vs. high suspicion-oriented) on the information provided by bluffers and actualisers. Drawing on psychological research examining lie detection, it was theorised that the need to be believed would be more urgent for bluffers than for actualisers. Hence, bluffers were expected to be more forthcoming when questioned about their threats and, in particular, when the questions communicated suspicion. As expected, bluffers provided more information in response to specific questions as compared to actualisers, especially with regard to implementation details (replicating Study I). However, the difference between bluffers and actualisers was not further accentuated by the use of suspicion-oriented questions. Furthermore, Study II explored whether threatening participants had used counter-interview strategies. Participants were found to be forthcoming, while also being strategic and adaptive to interviewers’ responses. Study III (N = 120) tested the hypothesis that rapport-based interviewing would be more effective for threat assessment and management purposes than direct interviewing. Against expectations, no differences were found between interview protocols pertaining to the threateners’ use of counter-interview strategies, their information provision, or their willingness to pursue/discuss the threat. Furthermore, the study advanced Study II by exploring what types of counter-interview strategies threateners employ. Again, threateners were found to be both forthcoming and strategic. The most frequently reported strategies were to prove capability and to conceal information. Study IV was an online study that investigated whether threat assessments made by professionals were of higher quality than those made by non-professionals. Threat assessment professionals, university students, and laypersons assessed the risk for violence in three fictitious cases. In alignment with the literature on expert decision-making, it was predicted that professionals (vs. students and laypersons) would agree more with one another with respect to risk assessments and that their information search would more resemble empirically supported threat cues. The results supported both hypotheses. Taking the results of the studies together, it could be concluded that threateners are semi-cooperative interviewees, whose attitudes may not be impacted by general interview approaches (e.g. rapport-based, suspicion-oriented). Instead, the findings suggest that more strategic techniques developed from the perspective of threateners (which result in their motivation to be informative prevailing over their need to be strategic) are needed.

Texte intégralRésumé :
Thesis (MBA)--Stellenbosch University, 2003.ENGLISH ABSTRACT: This study project aims to use "Real Option Analysis" as a tool to translate financial hedging strategies into business strategies that can be used to hedge business projects against their associated risks. Financial investments are often hedged by means of further investment in financial option structures. These option structures give the investor the option (and sometimes the obligation) to change the constituents of his original investment, depending on changes in the external environment. A well engineered option structure will protect the investor against downside risk, while maximizing profits from upside risk. The objective of this study project is then to adapt some of the standard structures to such an extent that they can be used with similar success in the real business environment. This adaptation is done by means of Real Option Analysis - a relatively new theory whereby business uncertainty and managerial flexibility can be evaluated and quantified in a way similar to financial options. It will be seen that a careful application of Real Option Analysis allows one to take a certain business situation, identify the risks inherent to it, find a suitable option structure to hedge against those risks, and modify this option structure so that it can be implemented as a pure business strategy. This analysis is supported by a detailed derivation of a popular Real Option Analysis model, and an in depth discussion of the differences between Real- and financial options as well as difficulties associated with the implementation of Real Option-based strategies. Several examples of specific business situations are analyzed and it is concluded that Real Option Analysis can provide useful, practical and competitive strategies. Above all, the thought process leading to said strategies is deemed to provide powerful insight into the dynamics of the business/project under evaluation.
AFRIKAANSE OPSOMMING: Hierdie studie projek poog om "Real Option Analysis" te gebruik om finansiele immuniserings strategiee om te skakel in besigheids strategiee wat gebruik kan word om besigheids projekte te beskerm teen hul inherente risikos. Finansiele beleggings word dikwels geimmuniseer deur middel van verdere beleggings in finansiele opsie strukture. Hierdie strukture gee aan die belegger die opsie (en soms die verpligting) om die samestelling van sy oorspronklike belegging aan te pas na gelang van veranderinge in die omgewing. 'n Goed ontwerpte struktuur sal die belegger toelaat om sy winste te maksimeer terwyl verliese as gevolg van negatiewe risiko beperk word. Die doel van die studie projek is dan om sommige van hierdie standaard opsie strukture aan te pas sodat dit nie net in die beleggings wereld nie, maar ook in die besigheids wereld toegepas kan word. Hierdie aanpassing word gedoen met behulp van "Real Option Analysis" - 'n relatief nuwe teorie waarvolgens besigheids onsekerhede and bestuurs aanpasbaarhede geevalueer en gekwantifiseer kan word op 'n soortgelyke wyse as finansiele opsies. Dit sal gesien word dat 'n deeglike toepassing van "Real Option Analysis" die gebruiker toelaat om 'n besigheids situasie te evalueer, die risikos daaran verbonde te identifiseer, 'n toepaslike opsie struktuur te vind wat beskerming sal bied teen hierdie risikos, en dan hierdie struktuur aan te pas sodat dit as 'n besigheid strategie toegepas kan word. Hierdie analise word ondersteun deur die afleiding van 'n populere "Real Option Analysis" model, 'n bespreking van die verskille tussen Rieele- en finansiele opsies, sowel as komplikasies wat verwag kan word tydens die implimentasie van 'n strategie gebasseer op Rieele Opsies. Verskeie voorbeelde van spesifieke besigheids situasies word geanaliseer en dit gee aanleiding tot die gevolgtrekking dat "Real Option Analysis" wel sinvolle, bruikbare en kompeterende strategiee kan voorsien. Verder word daar aangedui dat die denk proses wat lei tot hierdie strategiee, 'n kragtige bron van insig in die besigheid/projek dinamika kan gee.

Harrison, Pascale. « How individuals with Fibromyalgia manage their memory problems ». Thesis, University of the West of England, Bristol, 2012. https://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.572883.
Texte intégralRésumé :
Background: Previous studies have reported that there is both objective and subjective evidence that individuals with Fibromyalgia (FM) suffer from memory problems (Landro et al 1997; Katz et al 2004; Munoz et al 2005). The current literature has not examined how individuals cope with these difficulties. Aims of the study: The three aims were to: 1) measure the perceptions of managing memory problems for a FM population; 2) examine their coping response/strategies to establish if the responses can be explained by Models of Stress, Coping and Adjustment (The SRM and Transactional Model of Stress and Coping). 3) To explore the relationships between memory problems, mood, employment, health and pain. Methods: A mixed methodology design was adopted, within an internet survey. 100 participants (91 female, 4 males and 5 preferred to not answer) with FM were recruited from two FM Charity Websites. The modal age of the sample was 51-55 years old. 61 % of participants were from 'other' countries and 38% from the UK. Eight subjective questions (with comments) and psychometric tests were employed (Hospital Anxiety Depression Scale, Pain Catastrophizing Scale, Memory Aids Checklist and the Memory Complaint Questionnaire; and, demographic questions including employment). The questions were analysed using thematic analysis and inductive/deductive application of two theoretical models (Self Regulatory Model (Leventhal et al 2003) and Transactional Model of Stress and Coping (Lazarus et al 1984b). The data from the psychometric tests were analysed using SPSS (multiple regression and ANOVA). Results: Six themes emerged from the qualitative data, these were: "external memory aids"," impact upon daily life", "barriers that impact upon using strategies", "emotional well being", "other strategies and "denial of memory problems". The evidence from the themes implies that memory problems had a global impact upon a person's daily life: well being, home life, employment and coping behaviour. The SRM provided a framework for explaining the coping process. The Regression data proposed that depression significantly influenced perceptions of memory problems but not pain or anxiety. Conclusion: The outcome of this study suggests that both FM and memory problems impact upon well being by causing difficulties in the home and employment. The six themes suggest that memory problems can be managed by using external aids, family members/professionals and hobbies and interests. Recommendations from this research are that psycho-educational interventions would help to reduce memory problems and improve well being in this population.

This research had as objectives to study the genetic divergence of accessions of mangaba tree from three northeastern states, and from one midwest state of Brazil, and to observe the physicochemical and microbiological characteristics of fruits and pulps of mangaba harvested and processed With and Without Good Field Practices and With and Without Good Manufacturing Practices. Materials were collected, identified and transported to the Laboratory of Molecular Biology of the UFERSA, where, after using the right methodology and appropriate technique for extraction of DNA of genotypes, the molecular characterization of accessions of mangaba trees from three northeastern states ( PB , RN and PE ) and from one midwest state ( Mato Grosso ) was carried out . The results were analyzed in specific computer program, which also used cluster analysis (UPGMA) dendrogram in forming a chart that shows the genetic dissimilarities among genotypes. It was observed that the genotype originated from Mato Grosso had the highest coefficient of dissimilarity among the others, while the smallest dissimilarity was found between two genotypes from Paraíba. The experiment aiming to observe the physical, chemical and microbiological qualities of pulp and fruit of mangaba, using the Good Field Practices and Good Manufacturing Practices was performed at the Laboratory of Postharvest UFPB / CCA , where, with appropriate methodology, it was found great efficiency and effectiveness of the good field practices used (GFP), as well as the need to adopt and regulate this system in order to yield a better food quality, and, thereby ensuring the food security of the population . It also appears that, besides the need for adoption of the system, there is an urgent need for dissemination and awareness programs, so that they can also be tools in improving public health
Este trabalho teve como objetivos estudar a divergência genética de acessos de mangabeiras oriundas de três Estados do Nordeste e de um Estado do Centro Oeste do Brasil e observar as qualidades físico-químicas e microbiológicas de frutos e polpas de mangaba, colhidos e processados Com e Sem Boas Práticas de Campo e de Fabricação, respectivamente. Materiais foram colhidos, identificados, e transportados para o Laboratório de Biologia molecular da UFERSA, onde, após ser usada a metodologia e técnica apropriada para extração do DNA dos genótipos, se realizou a caracterização molecular de acessos de mangabeiras oriundas de três Estados do Nordeste (PB, RN e PE) e de um Estado do Centro Oeste (Mato Grosso). Os resultados foram analisados em programa computacional específico, onde se usou também a análise de agrupamento (UPGMA) formando um dendrograma que mostra, através de gráfico, as dissimilaridades genéticas entre os genótipos estudados. Observou-se que o genótipo oriundo do Mato Grosso teve o maior coeficiente de dissimilaridade entre os demais, enquanto que, a menor dissimilaridade ficou entre dois genótipos oriundos da Paraíba. O experimento objetivando observar a qualidade física, química e microbiológica de polpas e frutos de mangaba, utilizando-se as Boas práticas de Campo e de Fabricação, foi realizado no Laboratório de Pós- colheita da UFPB/CCA, onde foi utilizada toda a metodologia adequada, que constatou grande eficiência e eficácia desta prática utilizada (CBP), assim como, a necessidade da adoção e regulamentação deste sistema, visando dar uma melhor qualidade aos alimentos, e assim, garantir a segurança alimentar da população. Também se verifica que, além da necessidade de adoção do sistema, urge a necessidade de programas de difusão e conscientização, a fim de que, também sejam ferramentas na melhoria da saúde pública

Mangaba or Mangabeira (Hancornia speciosa) is better adapted to tropical climate drier climate and type of Brazilian cerrados board coasters, where its fruit in the future can be a nice source of food, although not significantly exploited commercially. This study aimed to provide data on the physical, physicochemical and evaluate the quantity of bioactive compounds and total antioxidant activity of different genotypes mangabeiras native of Ceará to obtain information relevant to the use and variability of this species. The fruits were physically characterized for total weight, size and pulp yield. For the evaluation of the physicochemical and chemical characteristics were analyzed: total acidity, total soluble sugar, pH, soluble solids, SS/TTA ratio, vitamin C, total pectin, yellow flavonoids, carotenoids, total extractable polyphenols (TEP) and total antioxidant activity (TAA) by ABTS and DPPH. With respect to the total weight was no big difference between genotypes, ranging from 8.55 g to 20.51 g with pulp yield range from 76.92% to 91.56%. The soluble solids showed high amplitude with a minimum value (17.30 ° Brix) and maximum (24.40 ° Brix). The genotypes showed an average of 10.26% for total sugar, low acid content ranging from 1.55% to 2.24% citric acid, with an average for the SS/TTA ratio of 10.59%. For vitamin C genotype that stood out was the G14 with a value of 269.66 mg/100 g with an average total value of 183.81 mg/100g. A wide variation was obtained for the TEP range from 161.45 to 366.83 mg/100g and average value of 220.06 mg/100g. With respect to the TAA genotypes showed an average of 13.18 mM Trolox / g pulp with the method of ABTS pulp and 5792.66 g / g DPPH for DPPH. There was significant positive correlation between total antioxidant activity by ABTS method with vitamin C (0.6133 **) and the DPPH method, the correlation was negative and significant (-0.669 **). The fruits of mangabeiras studied in this work in its present composition excellent quantities of bioactive compounds such as vitamin C, carotenoids, flavonoids and polyphenols extractable total. Highlighting the genotype 14 with the higher content of vitamin C among genotypes. Genotypes 5, 13 and 15 with the highest values of total antioxidant activity in ABTS method, among the genotypes. And for the total antioxidant activity in DPPH, highlighted the five genotypes, 14 and 15.
A mangaba ou mangabeira (Hancornia speciosa GOMES) se adapta melhor a clima tropical mais seco, clima tipo do cerrados brasileiro e tabuleiro costeiros, onde seus frutos podem constituir no futuro uma agradável fonte de alimento, embora ainda não sejam significativamente explorados comercialmente. Este trabalho teve por objetivo fornecer dados sobre as características físicas, físico-químicas e avaliar a quantidade dos compostos bioativos e atividade antioxidante total de diferentes genótipos de mangabeiras nativas do litoral cearense para a obtenção de dados relevantes para a utilização e variabilidade desta espécie. Os frutos foram caracterizados fisicamente quanto ao peso total, dimensões e rendimento em polpa. Para a avaliação das características físico-químicas e químicas foram feitas as seguintes análises: acidez total titulável, açúcares solúveis totais, pH, sólidos solúveis, relação SS/ATT, vitamina C, pectina total, flavonóides amarelos, carotenóides totais, polifenóis extraíveis totais (PET) e atividade antioxidante total (AAT) pelos métodos ABTS e DPPH. Com relação ao peso total houve grande diferença entre os genótipos, variando de 8,55g a 20,51g, com rendimento de polpa na faixa de 76,92% a 91,56%. Os sólidos solúveis apresentaram grande amplitude com valor mínimo (17,30°Brix) e valor máximo (24,40°Brix). Os genótipos avaliados apresentaram média de 10,26% para os açúcares totais, baixo teor de acidez com variação de 1,55% a 2,24 % de ácido cítrico, com média para a relação SS/AT de 10,59%. Para a vitamina C o genótipo que mais se destacou foi o G14 com valor de 269,66mg/100g com valor média total de 183,81mg/100g. obteve-se ampla variação para o PET com faixa de 161,45 a 366,83mg/100g e valor médio de 220,06mg/100g. Com relação a AAT os genótipos avaliados apresentaram média de 13,18μM Trolox/g polpa com o método do ABTS e 5792,66g polpa/g DPPH para o método do DPPH. houve correlação positiva e significativa entre a atividade antioxidante total pelo método ABTS com o teor de vitamina C (0,6133**) e para o método DPPH, a correlação foi negativa e significativa (-0,669**). Os frutos das mangabeiras estudados neste trabalho apresentam em sua composição excelente quantidades de compostos bioativos, tais como: vitamina C, carotenóides, flavonóides e polifenóis extraíveis totais. Destacando-se o genótipo 14 com o teor mais elevado de vitamina C entre os genótipos avaliados.

Com o objetivo de identificar o potencial da vegetação para o extrativismo, o conhecimento sobre uso de recursos vegetais nativos pela comunidade local e estimar a taxa máxima de coleta sustentável dos frutos de mangaba (Hancornia speciosa Gomes, Apocynaceae), foi realizado um estudo em uma área de cerrado remanescente na comunidade Água Boa 2, município de Rio Pardo de Minas, Norte de Minas Gerais. Na primeira parte do estudo, foi feito um levantamento fitossociológico e conduzidas entrevistas estruturadas com uma listagem livre sobre as dez plantas frutíferas e as dez madeireiras nativas mais usadas, seus principais locais de coleta e formas de uso, relacionando as informações com as categorias de gênero e idade. Na segunda parte, foi avaliada a estrutura e a dinâmica populacional, a produtividade e a germinação de H. speciosa, cujos frutos são explorados e comercializados. Também foram realizadas entrevistas semi-estruturadas com os extrativistas para caracterização da coleta de mangaba e da sua contribuição na renda familiar. No total, foram amostrados 673 indivíduos arbóreos, distribuídos em 22 famílias, 35 gêneros e 48 espécies em um hectare. A área basal total foi de 9,36 m2/ha e a densidade foi de 476 ind/ha. O índice de Shannon foi de 3,11 nats/ind, com equitabilidade de 0,8. Mangaba (H. speciosa), pequi (Caryocar brasiliense), rufão (Peritassa campestris), veludo (Sclerolobium paniculatum), sucupira (Bowdichia virgilioides) e jataipeba (Pterodon emarginatus) foram as espécies mais citadas e de maior Valor de Uso e Valor de Importância da Espécie. Os homens citaram mais espécies madeireiras que as mulheres e não foram encontradas diferenças significativas relacionadas à idade. Foram amostrados 390 indivíduos de mangaba, sendo 71,3 juvenis/ha, 15,0 reprodutivos jovens/ha e 6,7 reprodutivos maduros/ha. O Incremento Diamétrico Anual dos juvenis foi 0,25 cm; dos reprodutivos jovens foi 0,82 cm e dos reprodutivos maduros foi 0,42 cm. A taxa de mortalidade e de natalidade anual de juvenis foi de 2,8% e 10,6%, respectivamente. Nenhum indivíduo reprodutivo morreu durante o período de um ano. A germinação em viveiro (89,0%) foi maior que no campo (11,2%), e as plântulas do viveiro apresentaram crescimento maior que as do campo. Indivíduos adultos de mangaba produzem em média 80,1 frutos e cada fruto possui em média 5,2 sementes. A taxa de crescimento populacional (λ) foi de 1,18, e a taxa máxima de coleta sustentável é de 96%. Cada extrativista obtém uma renda média anual de R$ 15,00 a 30,00 por dois dias de coleta de frutos. O extrativismo, como praticado atualmente, aparentemente não está afetando a regeneração da espécie e os níveis atuais de coleta não representam ameaças à persistência da população em longo prazo. ___________________________________________________________________________________ ABSTRACT
For the purpose of identifying the harvesting potential of the vegetation, the knowledge about the use of native plant resources by the local community and to estimate the maximum sustainable harvesting rate of mangaba fruits (Hancornia speciosa Gomes, Apocynaceae), a study was carried out in a remaining cerrado area at Água Boa 2 community, municipality of Rio Pardo de Minas, north of Minas Gerais. In the first part of this study, a phytosociological survey was carried out and some structured interviews were conducted with a free list of the ten most used native fruit-bearing and timber plants, its main places of harvesting and manners of using, relating these information to age and gender categories. In the second part, an evaluation of the population structure and dynamics, productivity and germination of H. speciosa, which fruits are exploited and commercialized, were conducted. It was also applied semi-structured interviews to the harvesters in order to characterize the harvesting of mangaba and its contribution to family’s income. In total, 673 woody individuals, distributed in 22 families, 35 genus and 48 species were sampled in one hectare. The total basal area was 9.36 m2/ha with a density of 476 ind/ha. The Shannon index was 3.11 nats/ind, with 0.8 of equitabilility. Mangaba (H. speciosa), pequi (Caryocar brasiliense), rufão (Peritassa campestris), veludo (Sclerolobium paniculatum), sucupira (Bowdichia virgilioides) and jataipeba (Pterodon emarginatus) were the most quoted species with highest Use Value and Specie Importance Value. Men quoted more timber species than women with no significant differences related to age. It was sampled 390 mangaba individuals, with the density of 71.3 juveniles/ha, 15.0 young reproductives/ha and 6.7 mature reproductives/ha. Annual Diametrical Increment was 0.25 cm for juveniles; 0.82 cm for young reproductives and 0.42 cm for mature reproductives. Mortality and birth annual rates of juveniles were 2.8% and 10.6%, respectively. None of the reproductives died during the period of one year. Seed germination was higher in nursery (89.0%) than in the field (11.2%), and nursery seedlings grew more than the field ones. Mangaba’s adult trees produces on average 80.1 fruits and each fruit had on average 5.2 seeds. The population growth rate (λ) was 1.18 and the maximum sustainable harvesting rate was 96%. A harvester obtains on average an annual income of R$ 15.00 a 30.00 for two days of fruit harvesting. The present harvesting rate does not seem to affect regeneration in this population not threatening de long term persistence of this population.

Amid the expansion of capitalism processes in the field, the high concentration of land and production activities related to agribusiness, came the curiosity to pursue the study of spatial area that focuses on the city of Mauriti-Ce, from a discussion focused on the experiences developed in this municipality, by farmers who work with agroecological agriculture in the mandala system seeking to understand their social, economic and cultural development. Who has the ability to use the potential of the local agro-ecological production, valuing the traditional habits of the region, enabling social inclusion of family farmers, providing higher quality in agro-ecological products consumed in food, as well as preserving the diversity, respect the local culture and also permit the implementation of new markets for family farmers. In this context, said work has as main objective to analyze agroecological experiences in the city of Mauriti / EC, especially the organic system of the Mandalas. From the analysis of the epistemological foundations of organic agriculture, identify the experiences of farmers on organic farming, understanding the management of mandalas, realize technical assistance processes, diagnose experiences practices of organic agriculture and agroecology in the city, to understand agroecological experiences that occurred in the municipality of Mauriti-Ce, between the period 2008 to July 2016. The methodology is based on the work of Demo in 2002, is of great importance the basis of theoretical frameworks related to agroecology, the mandalas and to organic production systems. Conceptions also subjective conceptions and practices carried out by social actors surveyed, enable the understanding of the local reality from the method of participatory research with farmers working in the system in the municipality of Mauriti-Ce, with the use of questionnaires, and semi-structured interviews and informal conversations. After tabulating the data collected in the questionnaires, there was the aggregation through the analysis of primary and secondary elements in the incorporation of the information provided by farmers. With the deployment of the system, it was possible to observe social and economic benefits, such as the supply of safe food, quality and value in Mauriti municipality in the state of Ceará. It was also identified that the period analyzed the system did not succeed to all producers or communities due to factors such as the lack of technical assistance, demotivation of some producers, lack of participation in associations, although much be relevance of public policies for society and the economy, while not yet efficient to meet homogeneously throughout the public focus. It was identified that the mandala system Mauriti-Ce is a sustainable model of production that provides positive benefits to the economy. Thus, in the municipalities, especially small as is the case of the municipality studied, agriculture is of great importance not only for the economy, society and sustainable local development, but also for culture.
Em meio aos processos de expansão do capitalismo no campo, à elevada concentração de terra e a atividades de produção ligadas ao agronegócio, surgiu a curiosidade de realizar o estudo com recorte espacial que tem como foco o município de Mauriti-CE, a partir de uma discussão voltada para as experiências desenvolvidas nesse município, por agricultores familiares que trabalham com a agricultura agroecológica no sistema mandala em busca de compreender seu desenvolvimento social, econômico e cultural. O qual que tem a capacidade de utilizar as potencialidades da produção agroecológica local, valorizando os hábitos tradicionais da região, possibilitando a inclusão social dos agricultores familiares, fornecendo maior qualidade nos produtos agroecológicos consumidos na alimentação, além de preservar a diversidade, respeitar a cultura regional e também possibilitar a concretização de novos mercados para a agricultura familiar. Nesse contexto, o referido trabalho tem como objetivo principal analisar as experiências agroecológicas no município de Mauriti/CE, com destaque para o sistema orgânico de produção das mandalas. A partir da analise das bases epistemológicas da agricultura orgânica, identificar as experiências dos agricultores sobre a agricultura orgânica, entender o manejo das mandalas, perceber os processos de assistência técnica, diagnosticar as experiências práticas de agricultura orgânica e de agroecologia no município, para compreender as experiências agroecológicas que ocorreram no município de Mauriti-Ce, entre o período de 2008 a julho de 2016. A metodologia adotada é baseada no trabalho desenvolvido por Demo em 2002, sendo de grande importância o embasamento de referenciais teóricos relacionados à agroecologia, às mandalas e aos sistemas orgânicos de produção. Concepções também concepções subjetivas e práticas realizadas pelos atores sociais pesquisados, possibilitam o entendimento da realidade local a partir do método da pesquisa participante com os agricultores que trabalham nesse sistema no município de Mauriti-CE, com o uso de questionários, além de entrevistas semiestruturadas e conversas informais. Após a tabulação dos dados coletados na aplicação dos questionários, houve a agregação através da análise dos elementos primários e secundários na incorporação das informações prestadas pelos agricultores. Com a implantação do sistema, foi possível observar benefícios sociais e econômicos, como por exemplo, a oferta de alimentos seguros, com qualidade e valor agregado no Município de Mauriti no Estado do Ceará. Também foi identificado que no período analisado o sistema não teve êxito para todos os produtores ou comunidades, devido a alguns fatores como, por exemplo, a ausência de assistência técnica, desmotivação de alguns produtores, ausência de participação em associações, apesar de grande ser a relevância das políticas públicas para a sociedade e a economia, mesmo não sendo ainda eficientes para atender de forma homogênea a todo o público em foco. Identificou-se que o sistema mandala em Mauriti-CE é um modelo sustentável de produção que possibilita benefícios positivos para a economia. Assim sendo, nos municípios, principalmente de pequeno porte como é o caso do município estudado, a agricultura é de grande importância não só para a economia, sociedade e desenvolvimento local sustentável, mas também para a cultura.
