Pełny tekst źródłaDenna uppsats analyserar om det finns ett samband mellan den snabbt växande tyska exporten och produktutveckling. Genom en segmentering av den tyska tillverkningsindustriexporten i relation till olika produktgruppers internationella konkurrenskraft ges en möjlighet att undersöka skillnader mellan produktsegment med olika internationell konkurrenskraft. Analysen visar att i tidsperioden 2000 till 2002 definierades 76 av 240 produktgrupper ha haft en ökande internationell konkurrenskraft genom en relativ prishöjning. Detta är fler produktgrupper än i någon annan undersökt tidsperiod. De 76 produktgrupperna motsvarar 29,5 procent av det totala tyska exportvärdet, marginellt högre än i någon annan tidsperiod.
Produkter med ökande internationell konkurrenskraft genom en relativ prishöjning är också av ett högre värde per kilo export än andra konkurrenssegment. Analysen visare vidare att den internationella efterfrågan på dessa produktgrupper är signifikant högre än för produktgrupper med minskad internationell konkurrenskraft. Dock kunde inga generella skillnader mellan olika konkurrenssegment i relation till avståndskänslighet, kulturell och språklig affinitet samt EU-medlemskap på importandelen av tyska varor påvisas.
In this thesis the relationship between product development of the German manufacturing industry and the rapid German export growth is analyzed. By a segmentation of the German export according to international competitiveness, differences in characteristics of the different segments are analyzed. Positive for Germany is that in the time-period 2000 to 2002, 76 out of 240 analyzed product groups were defined as experienced increased export competi-tiveness through relative price increase; more than in any other analyzed time-period. These 76 product groups constituted 29.5 percent of Germany’s total export value, marginal higher than in any other time-period.
The analysis also shows that German product groups with increasing international competitiveness through relative price increase are of higher value than products in other competitive segments. The international demand for product groups with increasing international competitiveness through relative price increase is also higher than for other competitive segments. However, no general significant differences could be shown between different competitive segments in respect to distance sensitiveness, importance of cultural and linguistic affinity and EU-membership on the import share of German products.

Results of this survey suggested that the theory
surrounding the "product-process matrix" may be
inappropriate. Results also indicated the possibility that
row and column descriptions of the current "product-process
matrix" may need alterations in order to be more applicable
to manufacturing firms. Further research is necessary to
examine possible biases associated with the survey
instrument and survey sample. After such research has been
undertaken, it is recommended that continued work in this
area may help to improve understanding the interaction
between markets and manufacturing processes.

Pełny tekst źródłaO sector financeiro tem sido obrigado a repensar estratégias e a adaptar abordagens para conseguir acompanhar toda a disrupção tecnológica e social que se tem sentido, criando e aproveitando novas oportunidades de negócio. Atualmente, as instituições financeiras precisam de novas estratégias para reter os clientes atuais e capturar novos clientes, tal como a antecipação das suas necessidades. É neste contexto que surge o tema das necessidades financeiras de cada pessoa, um tema que carece de uma abordagem mais prática e realista, bem como de um enquadramento técnico adaptado ao tempo presente. Com este trabalho é ambicionado descrever as diferentes fases do ciclo de vida de uma pessoa, com base em dados recolhidos, e analisar de que modo é que os seus componentes têm influência na decisão do consumidor, relativamente à aquisição de produtos e serviços financeiros. É também pretendida a elaboração de um enquadramento da relação ciclo de vida ? necessidades financeiras e o desenvolvimento de um modelo que projete estas necessidades ao longo do ciclo e que otimize a propensão ao consumo, mediante a posição de cada pessoa no ciclo de vida. Esta análise revela pontos bastante relevantes, tal como a existência de correlação entre a ocorrência de certos eventos (como, por exemplo, casamento, nascimento de um filho) e a aquisição de produtos financeiros, um esquema detalhado da relação entre o ciclo de vida e as necessidades financeiras e ainda um modelo que prevê a melhor oferta de produtos e serviços financeiros para cada cliente.
The constant change that has been noticeable on a worldwide level has impacted the economical, geopolitical and social frameworks, with direct repercussions across every sector. For example, the financial sector is compelled to rethink strategies and to adapt its procedures in order to be up to date with respect to the current technological and social disruption, thus creating new business methods and opportunities. Currently, the financial institutions need new approaches to retain and to capture clients, such as knowing them and anticipating their needs. It is in this context that the concept of financial necessities arises, a subject that needs academic and professional investigation. With this work, it is intended to describe the different stages of the human life cycle, according to data collected during the project, and to provide an analysis on how its components are related to the decision process of acquiring financial products and services. It is also expected to provide a framework to the life cycle - financial necessities relationship and to develop a statistical model that predicts these needs throughout the life cycle and optimizes the propensity to consumption of financial products and services. The analysis carried out in this work discloses relevant insights, such as the existence of correlation between typical life events (e.g. marriage or childbirth) with the acquisition of financial products, a detailed framework of the life cycle - financial needs relationship and a predictive model which outputs the next best offer for clients.

Pełny tekst źródłaENGLISH ABSTRACT: The mother-daughter relationship and the feminine principle in the process of individuation are explored in this study. The mother-daughter relationship as the focus of the study is presented as the womb where the stories and experiences are in gestation. In presenting this research as a transpersonal exploration, the principles and practices of transpersonal psychology and transpersonal research are used as the lens through which the process of research is viewed. The study tells the stories of adolescent daughters and their menopausal mothers and their lives as girls and women in transitional life cycles. It also tells the stories of the author's mother and of herself, and offers their shared experiences of being daughters, and remembering that they are also the daughters of daughters, the mothers of whom have passed away a long time ago. The stories are presented in the mode of a narrative inquiry, becoming an exploration in itself. The author looks into the stories of what has been written by those who have mapped the territory of the transpersonal and narrative landscapes in psychology, education, research and psychotherapy. A research collage of the mother-daughter relationship, transitional life cycles, and also of aspects of the feminine and the process of individuation is created. Images of alchemy, archetypes, mythological figures and archetypal goddesses are added to allow this collage to become its own story. The study combines research methods used in transpersonal research and narrative inquiry. Data were gathered by making use of journal writing, mandala drawings, interviews, visual imagery and photographs, collage, writing letters, personal documentation, dreamwork, working with words and personal mythology. Transpersonal principles such as meditation, reflection, mandala drawings, intuitive listening and so forth were applied in working with the data. The researcher also used principles of narrative inquiry to assist in the process of processing the information and finding the stories. The research findings that emerged indicate that a mother and daughter can hold up a mirror to each other in order to see that there are experiences of abandonment and dependency in their relationship; another mother and daughter pair related to each other from a basis of limiting self-experience; and yet another mother and her daughter were seen to have a relationship that contains powerful potential for individuation through the process of growth and transformation. These findings may be relevant to the therapeutic and educational spheres of psychology, in training and in application. This research journey is an adventure that can be seen as symbolically walking the labyrinth, following the circular path towards the centre, and then back again, out into life. This journey is symbolic of the process of individuation as based on the mythology of the serpent Ouroboros that swallows its tail in order to become whole. The process of alchemy in psychology forms the container for this journey into wholeness. Like Theseus, beloved of Ariadne of antiquity, I took the golden thread in hand and stepped into the labyrinth. The journey could begin …
AFRIKAANSE OPSOMMING: Hierdie studie verken die moeder-dogter verhouding en die vroulike beginsel in die individuasieproses. Die moeder-dogterverhouding as die fokus van hierdie studie word voorgestel as 'n houer vir die bewaring van belangrike aspekte van die vroulike beginsel. Die modus van transpersoonlike sielkunde en navorsing is gebruik om as 'n lens te dien waardeur hierdie proses ondersoek is. Die narratiewe navorsingsmetode is gebruik om die stories te vertel wat in hierdie studie aangebied word. Hierdie stories gaan oor die navorsingsreis, die reis van dogter-wees en moeder-wees, die reis van vrou-wording en vrou-wees in die oorgangsfases van vroue se lewens. Dit behels stories van adolessensie en die menopouse. Daarnaas geplaas is die stories van my moeder, van myself, en van ons verhouding. In hierdie vertelling oor die moeder skryf ek dit as die dogter van 'n dogter wie se moeder lank reeds oorlede is. Ek onderneem 'n reis deur die landskap van die literatuur en neem daaruit stories van aspekte van vrou-wees, van die vroulike beginsel, asook van transpersoonlike sielkunde en transpersoonlike navorsing. Dit gaan ook oor die narratiewe wyse van ondersoek en die waarde van stories in narratiewe terapie word bespreek. Hierdie navorsingsreis is 'n speurtog; soos in 'n labirint is dit 'n sirkelvormige reis, wat die mitologiese slang, Ouroboros, wat sy eie stert insluk om heel te word weerspieël. Die labirinte van die mitologie en argetipiese vroubeelde en godinne stem tot nadenke oor die sielkundige ervaring van individuasie. In die nadenke is daar, soos met die alchemiste van weleer, 'n soeke die goud in die lood en die bevindinge wat die navorsingsreis oplewer, word bekendgemaak. In hierdie reis is gebruik gemaak van transpersoonlike en narratiewe navorsingsmetodes en beginsels om die inligting te verkry waarmee die stories vertel kon word. Hierdie metodes maak onder meer gebruik van joernaalskryf, mandalas teken, onderhoude, visuele beelde en foto's, collage, briewe, persoonlike dokumente, droomwerk, woorde en woordassosiasie en persoonlike mitologie. Transpersoonlike werkswyses soos meditasie, refleksie, intuitiewe luister, joernaal skrywe en so meer is gekombineer met narratiewe werkswyses om die inligting te verwerk en die stories te ontgin. Die navorsingsbevindinge dui op ervaringe van afhanklikheid en vrese van verlating; van 'n moeder en dogter wat gebuk gaan onder beperkende ervaringe van selfvertwyfeling en die implikasie wat dit het vir hulle vrou-wees; van 'n moeder en haar dogter wat die potensiaal vir die proses van individuasie in hulle verhoudinge met hul vroueliggame vind. Die implikasies van hierdie bevindinge mag moontlik van belang wees vir sielkundiges en opvoedkundiges wat hulle in hierdie sfere van hulpverlening bevind. Soos Theseus, beminde van Ariadne van ouds, het ek die goue draad ter hand geneem en daarmee die ingang van die labirint betree. Die reis moes begin …

Among vascular plants/ different life cycles are associated with characteristic ranges of propagule size. In the modern flora, isospores of homosporous pteridophytes are almost all smaller than 150 urn diameter, megaspores of heterosporous pteridophytes fall in the range 100-1000 urn diameter, gymnosperm seeds are possibly all larger than the largest megaspores, but the smallest angiosperm seeds are of comparable size to large isospores. -- Propagule size is one of the most important features of a sporophyte's reproductive strategy. Roughly speaking, larger propagules have larger food reserves, and a greater probability of successful establishment, than smaller propagules, but a sporophyte can produce more smaller propagules from the same quantity of resources. Different species have adopted very different size-versus-number compromises. The characteristic ranges of propagule size, in each of the major groups of vascular plants, suggest that some life cycles are incompatible with particular size-versus-number compromises. -- Sex expression in homosporous plants is a property of gametophytes (homosporous sporophytes are essentially asexual). Gametophytes should produce either eggs or sperm depending on which course of action gives the greatest chance of reproductive success. A maternal gametophyte must contribute much greater resources to a young sporophyte than the paternal gametophyte. Therefore, smaller gametophytes should tend to reproduce as males, and gametophytes with abundant resources should tend to reproduce as females. Consistent with these predictions, large female gametophytes release substances (antheridiogens) which induce smaller neighbouring ametophytes to produce sperm. -- The mechanism of sex determination in heterosporous species appears to be fundamentally different. Large megaspores develop into female gametophytes, and small icrospores develop into male gametophytes. Sex expression appears to be determined by the sporophyte generation. This is misleading. As argued above, the optimal sex expression of a homosporous gametophyte is influenced by its access to resources. This is determined by (1) the quantity of food reserves in its spore and (2) the quantity of resources accumulated by the gametophyte's own activities. If a sporophyte produced spores of two sizes, gametophytes developing from the larger spores' would be more likely to reproduce as females than gametophytes developing from the smaller spores, because the pre-existing mechanisms of sex determination would favor production of archegonia by larger gametophytes. Thus, the predicted mechanisms of sex determination in homosporous species could also explain the differences in sex expression of gametophytes developing from large and small spores in heterosporous species.
Megaspores of living heterosporous pteridophytes contain sufficient resources for female reproduction without photosynthesis by the gametophyte (Platyzoma excepted), whereas microspores only contain sufficient resources for male reproduction. Furthermore, many more microspores are produced than megaspores. A gametophyte's optimal sex expression is overwhelmingly determined by the amount of resources supplied in its spore by the sporophyte, and is little influenced by the particular environmental conditions where the spore lands. Gametophytes determine sex expression in heterosporous species, as well as homosporous species. A satisfactory model for the evolution of heterospory needs to explain under what circumstances sporophytes will benefit from producing spores of two distinct sizes. -- In Chapter 4, I present a model for the origin of heterospory that predicts the existence of a "heterospory threshold". For propagule sizes below the threshold, homosporous reproduction is evolutionarily stable because gametophytes must rely on their own activities to accumulate sufficient resources for successful female reproduction. Whether a gametophyte can accumulate sufficient resources before its competitors is strongly influenced by environmental conditions. Gametophytes benefit from being able to adjust their sex expression in response to these conditions. For propagule sizes above the threshold, homosporous reproduction is evolutionarily unstable, because the propagule's food reserves are more than sufficient for a "male" gametophyte to fertilize all eggs within its neighbourhood. A population of homosporous sporophytes can be invaded by sporophytes that produce a greater number of smaller spores which could land in additional locations and fertilize additional eggs. Such'spores would be male-specialists on account of their size. Therefore, both spore types would be maintained in the population because of frequency-dependent selection. -- The earliest vascular plants were homosporous. Several homosporous groups gave rise to heterosporous lineages, at least one of which was the progeniture of the seed plants. The first heterosporous species appear in the Devonian. During the Devonian, there was a gradual increase in maximum spore size, possibly associated with the evolution of trees and the appearance of the first forests. As the heterospory threshold was approached, the optimal spore size for female reproduction diverged from the optimal spore size for male reproduction. Below the threshold, a compromise spore size gave the highest fitness returns to sporophytes, but above the threshold, sporophytes could attain higher fitness by producing two types of spores. -- The evolution of heterospory had profound consequences. Once a sporophyte produced two types of spores, microspores and megaspores could become specialized for male and female function respectively. The most successful heterosporous lineage (or lineages) is that of the seed plants. The feature that distinguishes seed plants from other heterosporous lineages is pollination, the capture of microspores before, rather than after, propagule dispersal. Traditionally, pollination has been considered to be a major adaptive advance because it frees sexual reproduction from dependence on external fertilization by freeswimming sperm, but pollination has a more important advantage. In heterosporous pteridophytes, a megaspore is provisioned whether or not it will be fertilized whereas seeds are only provisioned if they are pollinated.
The total cost per seed cannot be assessed solely from the seed's energy and nutrient content. Rather, each seed also has an associated supplementary cost of adaptations for pollen capture and of resources committed to ovules that remain unpollinated. The supplementary cost per seed has important consequences for understanding reproductive strategies. First, supplementary costs are expected to be proportionally greater for smaller seeds. Thus, the benefits of decreasing seed size (in order to produce more seeds) are reduced for species with small seeds. This effect may explain minimum seed sizes. Second, supplementary costs are greater for populations at lower density. Thus, there is a minimum density below which a species cannot maintain its numbers. -- By far the most successful group of seed plants in the modern flora are the angiosperms. Two types of evidence suggest that early angiosperms had a lower supplementary cost per seed than contemporary gymnosperms. First, the minimum size of angiosperm seeds was much smaller than the minimum size of gymnosperm seeds. This suggests that angiosperms could produce small seeds more cheaply than could gymnosperms. Second, angiosperm-dominated floras were more speciose than the gymnosperm-dominated floras they replaced. This suggests that the supplementary cost per seed of angiosperms does not increase as rapidly as that of gymnosperms, as population density decreases. In consequence, angiosperms were able to displace gymnosperms from many habitats, because the angiosperms had a lower cost of rarity. -- Angiosperm embryology has a number of distinctive features that may be related to the group's success. In gymnosperms, the nutrient storage tissue of the seed is the female gametophyte. In most angiosperms, this role is taken by the endosperm. Endosperm is initiated by the fertilization of two female gametophyte nuclei by a second sperm that is genetically identical to the sperm which fertilizes the egg. Endosperm has identical genes to its associated embryo, except that there are two copies of maternal genes for every copy of a paternal gene. -- Chapter 9 presents a hypothesis to explain the unusual genetic constitution of endosperm. Paternal genes benefit from their endosperm receiving more resources than the amount which maximizes the fitness of maternal genes, and this conflict is expressed as parent-specific gene expression in endosperm. The effect of the second maternal genome is to increase maternal control of nutrient acquisition. -- Female gametophytes of angiosperms are traditionally classified as monosporic, bisporic or tetrasporic. Bisporic and tetrasporic embryo sacs contain the derivatives of more than one megaspore nucleus. Therefore, there is potential for conflict between the different nuclear types within an embryo sac, but this possibility has not been recognized by plant embryologists. In Chapter 10, I show that many previously inexplicable observations can be understood in terms of genetic conflicts within the embryo sac.

Pełny tekst źródłaThe increasing use of the transition terms in the public debate contributes to the emergence of new research methods whom geographers begin to apprehend. Transition invites to consider a new action framework. In the matter of energy domain, the transition concept involves geographers in their socio-spatial interpretations. This new spatiotemporal frame, where are introduced the notions of territorialisation of the energy and the reversibility, provides an opportunity to consider these issues from a reinterpretation of the space-time couple. In this context, the thesis aims in understanding and analyzing of socio-spatial mechanisms tested by the renewable energies development, especially wind turbines. The specificity of this approach may be a geographical rendition of the Life Cycle Assessment method. For this purpose, the thesis requires the concept of landscape in its dynamic meaning. However, the life cycle assessment invites us to reshape the idea of landscape dynamics according to the notion of event. The thesis explores the arrival of a wind turbines project as an event and it focus on its sudden emergence, the induced socio-spatial destabilizations and the individual and social adaptations. The purpose of this research is to investigate a Social Life Cycle Assessment of the landscape representations of the wind energy. This ambition faces a time constraint. The allowed time of a PhD thesis faces political times and the times of the experience. Created events or suffered events impact the socio-spatial representations differently and over various timescales. Considering a diachronic study brings about rethinking the epistemological and methodological issues raised by a corpus which gathers several types of data, from different sources and which would be analyzed together. The analysis is led on discourses and especially on spatial textual references along with the individual sensibilities revealed when a wind turbines project is initiated on territory. The thesis tracks the life cycle steps of windpower-events that we interpret according to the socio-spatial context of the study terrains
