A total of 4063 young bulls of two tropical genotypes (1639 Brahman and 2424 Tropical Composite) raised in northern Australia were evaluated for a comprehensive range of production and reproduction traits up to 24 months of age. Prior to weaning, peripheral blood concentrations of luteinising hormone (LH) and inhibin were measured at 4 months of age. At weaning (6 months) blood insulin-like growth factor-1 (IGF-I) and flight time were recorded. Body composition traits of fat depth and eye-muscle area were determined by ultrasonography at 15 months of age when additional measurements of liveweight, hip height and body condition score were recorded. Bull breeding soundness was evaluated at similar to 12, 18 and 24 months of age when measurements of scrotal circumference, sheath score, semen mass activity, progressive motility of individual sperm and percent morphologically normal sperm were recorded. Magnitude of heritability and genetic correlations changed across time for some traits. Heritability of LH, inhibin, IGF-I and of 18-month scrotal circumference, mass activity, progressive motility and percent normal sperm was 0.31, 0.74, 0.44, 0.75, 0.24, 0.15 and 0.25, respectively, for Brahmans and 0.48, 0.72, 0.36, 0.43, 0.13, 0.15 and 0.20, respectively, for Tropical Composites. Inhibin and IGF-I had moderate genetic association with percent normal sperm at 24 months in Brahmans but low to negligible associations in Tropical Composites. Body condition score in Brahmans and sperm motility (mass and individual) traits in both genotypes had moderate to strong genetic correlation with percent normal sperm and may prove useful candidates for indirect selection. There is scope to increase scrotal circumference by selection and this will be associated with favourable correlated responses of improved semen quality in both genotypes. The lack of genetic antagonism among bull traits indicates that selection for improved semen quality will not adversely affect other production traits.

Reproductive philopatry in bull sharks Carcharhinus leucas was investigated by comparing mitochondrial (NADH dehydrogenase subunit 4, 797 base pairs and control region genes 837 base pairs) and nuclear (three microsatellite loci) DNA of juveniles sampled from 13 river systems across northern Australia. High mitochondrial and low microsatellite genetic diversity among juveniles sampled from different rivers (mitochondrial fST = 0.0767, P < 0.05; microsatellite FST = -0.0022, P > 0.05) supported female reproductive philopatry. Genetic structure was not further influenced by geographic distance (P > 0.05) or long-shore barriers to movement (P > 0.05). Additionally, results suggest that C. leucas in northern Australia has a long-term effective population size of 11 000-13 000 females and has undergone population bottlenecks and expansions that coincide with the timing of the last ice-ages.

Genetic correlations of young bull and heifer puberty traits with measures of early and lifetime female reproductive performance were estimated in two tropical beef cattle genotypes. Heifer age at puberty was highly (r(g) = -0.71 +/- 0.11) and moderately (r(g) = -0.40 +/- 0.20) genetically correlated with pregnancy rate at first annual mating (mating 1) and lifetime annual calving rate, respectively in Brahman (BRAH). In Tropical Composite (TCOMP), heifer age at puberty was highly correlated with reproductive outcomes from the first re-breed (mating 2), mainly due to its association with lactation anoestrous interval (r(g) = 0.72 +/- 0.17). Scrotal circumference were correlated with heifer age at puberty (r(g) = -0.41 +/- 0.11 at 12 months in BRAH; -0.30 +/- 0.13 at 6 months in TCOMP) but correlations were lower with later female reproduction traits. Bull insulin-like growth factor-I was correlated with heifer age at puberty (r(g) = -0.56 +/- 0.11 in BRAH; -0.43 +/- 0.11 in TCOMP) and blood luteinising hormone concentration was moderately correlated with lactation anoestrous interval (r(g) = 0.59 +/- 0.23) in TCOMP. Semen quality traits, including mass activity, motility and percent normal sperm were genetically correlated with lactation anoestrus and female lifetime female reproductive traits in both genotypes, but the magnitudes of the relationships differed with bull age at measurement. Preputial eversion and sheath scores were genetically associated with lifetime calving and weaning rates in both genotypes. Several of the early-in-life male and female measures examined were moderately to highly genetically correlated with early and lifetime female reproduction traits and may be useful as indirect selection criteria for improving female reproduction in tropical breeds in northern Australia.

The aim of this thesis was to examine the understanding of community in George Lindbeck s The Nature of Doctrine. Intrinsic to this question was also examining how Lindbeck understands the relation between the text and the world which both meet in a Christian community. Thirdly this study also aimed at understanding what the persuasiveness of this understanding depends on. The method applied for this task was systematic analysis. The study was conducted by first providing an orientation into the nontheological substance of the ND which was assumed useful with respect to the aim of this study. The study then went on to explore Lindbeck in his own context of postliberal theology in order to see how the ND was received. It also attempted to provide a picture of how the ND relates to Lindbeck as a theologian. The third chapter was a descriptive analysis into the cultural-linguistic perspective, which is understood as being directly proportional to his understanding of community. The fourth chapter was an analysis into how the cultural-linguistic perspective sees the relation between the text and the world. When religion is understood from a cultural-linguistic perspective, it presents itself as a cultural-linguistic entity, which Lindbeck understands as a comprehensive interpretive scheme which structures human experience and understanding of oneself and the world in which one lives. When one exists in this entity, it is the entity which shapes the subjectivities of all those who are at home in this entity which makes participation in the life of a cultural linguistic entity a condition for understanding it. Religion is above all an external word that moulds and shapes our religious existence and experience. Understanding faith then as coming from hearing, is something that correlates with the cultural-linguistic depiction of reality. Religion informs us of a religious reality, it does not originate in any way from ourselves. This externality linked to the axiomatic nature of religion is also something that distinguishes Lindbeck sharply from liberalist tendencies, which understand religion as ultimately expressing the prereflective depths of the inner self. Language is the central analogy to understanding the medium in which one moves when inhabiting a cultural-linguistic system because language is the transmitting medium in which the cultural-linguistic system is embodied. The realism entailed in Lindbeck s understanding of a community is that we are fundamentally on the receiving end when it comes to our identities whether cultural or religious. We always witness to something. Its persuasiveness rests on the fact that we never exist in an unpersuaded reality. The language of Christ is a self-sustaining and irreducible cultural-linguistic entity, which is ontologically founded upon Christ. It transmits the reality of a new being. The basic relation to the world for a Christian is that of witnessing salvation in Christ: witnessing Christ as the home of hearing the message of salvation, which is the God-willed way. Following this logic, the relation of the world and the text is one of relating to the world from the text, i.e. In Christ through the word (text) for the world, because it assumes it s logic from the way Christ ontologically relates to us.

Descreve, tomando por base uma fotografia de 1865, algumas iniciativas para preservação da natureza realizadas no Brasil durante o século XIX. Resume dados biográficos do suíço George Leuzinger, dando ênfase a preocupação ecológica desse fotógrafo. Afirma a necessidade de transformar o ser humano em "parasita do Bem", extraindo do planeta Terra o seu sustento, mas retribuindo com a correção dos malefícios feitos até agora.
