The effects of green perceived value and altruism on green consumption – A study on generations

Dissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Marketing IntelligenceGuaranteeing the future of the planet becomes ever more urgent as population increases and resources become scarce. Moving towards green consumption habits proposes one of the solutions, thus, understanding its drivers is crucial. The present research assesses the effects of green perceived value and altruism types on sustainable buying intentions, behaviour and willingness to pay and investigates differences between generations: Baby Boomers, Generation X and Millennials and Centennials. Findings suggest altruism, namely pure altruism, to be the main driver for sustainable buying intentions and behaviour and reveals that the generations furthest apart (Baby Boomers and Millennials and Centennials) present the main difference against Generation X

Distribution and diversity of exotic plant species in montane to alpine areas of Kosciuszko National Park

Diversity and distribution of exotic plant taxa in Kosciuszko National Park in south-eastern Australia were reviewed based on 1103 records of exotics from 18 vegetation surveys conducted between 1986 and 2004. 154 taxa from 23 families were recorded in the alpine to montane zones, with eleven taxa in the alpine, 128 taxa in the subalpine and 69 taxa in the montane zone. Nearly all taxa were associated with anthropogenic disturbance with only four taxa exclusively recorded in natural areas. 62 taxa were recorded from subalpine ski resort gardens, and although not recorded as naturalised in the vegetation surveys, their presence in the Park is a concern. Road verges provided habitat for numerous exotics (65 taxa). 44 taxa were recorded in both disturbed and natural locations but most were uncommon (33 taxa < 2% frequency). Nine common taxa Acetosella vulgaris, Achillea millefolium, Agrostis capillaris, Anthoxanthum odoratum, Cerastium spp., Dactylis glomerata, Hypochaeris radicata, Taraxacum officinale and Trifolium repens comprised 68% of records. These species are common to disturbed areas in other areas of Kosciuszko National Park, NSW and worldwide. The forb Acetosella vulgaris was the most ubiquitous species particularly in natural areas where it was recorded at 36% frequency. Based on the data presented here and a recent review of other data sets, there are at least 231 exotic taxa in the Park (including exotics in gardens). The increasing diversity and abundance of exotics is a threat to the natural values of this Park

Polyhedral geometry of Phylogenetic Rogue Taxa

It is well known among phylogeneticists that adding an extra taxon (e.g. species) to a data set can alter the structure of the optimal phylogenetic tree in surprising ways. However, little is known about this "rogue taxon" effect. In this paper we characterize the behavior of balanced minimum evolution (BME) phylogenetics on data sets of this type using tools from polyhedral geometry. First we show that for any distance matrix there exist distances to a "rogue taxon" such that the BME-optimal tree for the data set with the new taxon does not contain any nontrivial splits (bipartitions) of the optimal tree for the original data. Second, we prove a theorem which restricts the topology of BME-optimal trees for data sets of this type, thus showing that a rogue taxon cannot have an arbitrary effect on the optimal tree. Third, we construct polyhedral cones computationally which give complete answers for BME rogue taxon behavior when our original data fits a tree on four, five, and six taxa. We use these cones to derive sufficient conditions for rogue taxon behavior for four taxa, and to understand the frequency of the rogue taxon effect via simulation.Comment: In this version, we add quartet distances and fix Table 4

Bryophytes and their distribution in the Blue Mountains region of New South Wales

The bryophytes (mosses, liverworts and hornworts) that occur in the Blue Mountains region of New South Wales (latitude 33˚–34˚ S, longitude 151˚–151˚40’ E) are listed and information is provided on their distribution in the region. Species lists are based on herbarium specimens and field collections. 348 bryophyte taxa have been recorded from 70 families, including 225 moss taxa (in 108 genera from 45 families), 120 liverwort taxa (in 51 genera from 24 families) and 3 hornwort taxa (in 3 genera from one family). The moss families with most taxa are the Pottiaceae (with 23 taxa in 13 genera), Bryaceae (with 15 taxa in 3 genera) and Fissidentaceae (with 13 taxa). The largest genera are Fissidens (13 taxa), Campylopus (9) and Macromitrium (8). The liverwort family with the most taxa is Lepidoziaceae, with 29 taxa in 10 genera. The largest liverwort genera are Frullania (11 taxa) and Riccardia (8). The species lists include collections from both bushland and urban areas. Natural features of the Blue Mountains, including topography, altitude, climate and vegetation appear to be important factors influencing the number of bryophyte species recorded from each location. The number of collections from particular locations has been considerably influenced by ease of access, particularly proximity to roads, public transport and railway stations. The species lists include many records from areas that were not accessible to the early collectors of the late 19th and early 20th centuries such as Wollemi National Park, Gardens of Stone National Park, Newnes Plateau and Kanangra-Boyd National Park

O assistente e o segredo de justiça em processo penal

Dissertação de mestrado em direito. Ciências jurídico-processuaisSendo o Direito uma área do saber tão apaixonante, tal sentimento advém em larga medida, do leque de vários intervenientes jurídicos existentes, bem como da intervenção destes, que variando a situação e disciplina jurídica, leva à também variação da sua capacidade e legitimidade em agir e interagir juridicamente com o ordenamento vigente na nossa “praxis”. Nesta dissertação dá-se enfoque a uma das figuras jurídicas mais dinâmicas do nosso ordenamento jurídico em sede de Direito Processual Penal, no caso o “assistente”. Resumidamente, o que se pretendeu, através de uma apresentação jurisprudencial em quatro capítulos, foi desde logo, tal como aconteceu no primeiro, compreender que a figura da assistência, não é estática, e que por isso foi alvo de alterações, conforme se alterou também o entendimento processual penal do legislador Português, balizando-se este estudo na segunda metade do século XIX até aos dias de hoje, destacando-se duas realidades de especial relevo, sendo estas as grandes reformas de 1987 e 2006/2007. Por se procurar neste momento apenas fazer um breve resumo à matéria tratada, entende-se não ser este o momento para excessivos alargamentos jurisprudenciais, pelo que no que diz respeito aos segundo e terceiro capítulos, dever-se-á quanto baste dizer que o “assistente” é um colaborador do Ministério Público, característica, que lhe confere especial importância, mas sendo ainda revestido de direitos e deveres próprios, o que por outro lado impede que o próprio caia na tentação de actuar erraticamente, como muito bem lhe aprouver. Nos dois últimos capítulos da dissertação, estudou-se a ligação entre o “assistente” e o segredo de justiça, e toda a problemática que a esta ligação está adstrita, pelo excesso de mediatismo sustentado pelos meios de comunicação social, dado que se podem constituir assistentes, contribuindo para fugas ao segredo de justiça não só de Portugal, como em todos os ordenamentos jurídicos nesta dissertação apresentados

Diversity and altitudinal niche width characteristics for 35 taxa of the Papua New Guinea Frullania flora with consideration of sibling pairs

The Frullania taxa on Mount Albert Edward, Papua New Guinea, form many associations that suggest a high degree of niche similarity, but at different altitudes, different associations form. The species diversity of the genus is greatest at the middle altitudes and least in the dry lowlands. This altitudinal separation is apparent in the niche widths of the taxa. The members of the four sibling taxa pairs examined exhibit distinct altitudinal niches, suggesting that the sibling taxa are distinct, with different niche optima
