The author explores the Christian doctrine of the Trinity to shed light on the nature of the pastoral ministry. Using the trinitarian term, "polyphony" (David Cunningham) for this purpose, he explicates unity and difference as key polyphonic categories in the doctrine of the Trinity. The author suggests that the polyphonic notes sounded by pastoral caregivers are toughness and tenderness, woundedness and health, wisdom and folly, and communion, nearness and distance.

Optimal intertemporal investment behaviour of Australian pastoralists is modelled using panel data for the period 1979-1993. Results indicate that quasi-fixity of inputs of labour, capital, sheep numbers and cattle numbers is characteristic of production in the pastoral region. It takes about two years for labour, four years for capital and a little over two years for both sheep numbers and cattle numbers to adjust towards long-run optimal levels. Results also indicate that, after accounting for adjustment costs, own-price product supply and input demand responses are inelastic in both the short and long run.

Parthenium weed (Parthenium hysterophorus L.) is a new and potentially major weed in Pakistan. This weed, originating from central America, is now a major weed in many regions of the world including Eastern Africa, India, parts of South East Asia and Australia. Presumably its recent arrival in Pakistan has been due to its movement from India, but this has yet to be established. In Australia it has been present for about 50 years, in which time it has spread from isolated infestations to establish core populations in central Queensland with scattered and isolated plants occurring south into New South Wales and north-west into the Northern Territory. Its spread in Pakistan is likely to be much more rapid, but lessons learnt in Australia will be of great value for weed managers in Pakistan. This annual herb has the potential to spread to all medium rainfall rangeland, dairy and summer cropping areas in Pakistan. In Australia its main effect is upon livestock production, but it is also causing health concerns in regional communities. However, in India it has also had a significant impact in cropping systems. To help coordinate actions on its management in Australia, a National Weeds Program has created a Parthenium Weed Management Group (PWMG) and under this group a Parthenium Weed Research Group (PWRG) has been formed. Funding coming from this national program and other sources has supported the PWRG to undertake a collaborative and technology exchange research program in two main areas: 1) biology and ecology and 2) management; while the PWMG has focused on community awareness and the production of various extension and management packages. Research in the area of biology and ecology has included studies on the evaluation of competitive plants to displace parthenium weed, the use of process-based simulation models to monitor and predict future spread and abundance under present and future climate conditions, the effect of the weed on human health and the ecology of its seed bank. Management research has focussed on the development of biological control approaches using plant-feeding insects and pathogens. The effectiveness of biological control is also being monitored through long term studies on seed bank size and dynamics. The use of fire as another potential management tool is also being evaluated. In addition to this important research, an effort has also been made to spread the most important findings and management outcomes to the wider community through an extension and education program driven by the PWMG. These developments within Australia, in parthenium weed management, will be of great help to P

A proposta do presente estudo é verificar a ação pastoral da Igreja Católica junto ao povo de rua da cidade de São Paulo, tendo como objetivo formar um conceito teórico sobre a contribuição social da pastoral em um contexto urbano, a partir da ação de Entid ades de apoio ao povo de rua. A metodologia utilizada foi a bibliográfica. As implicações do estudo foram o direcionamento que a práxis pastoral está direcionada à priorização da superação e do reconhecimento da necessidade material e psicossocial de quem está morando na rua. A concretização da práxis se dá por meio de uma prática interventora sócio-politica, a qual visa a efetivação de medidas públicas para uma demanda de pessoas que usam a rua como moradia. A ação pastoral contribui ao mostrar a ausência de política pública que dificulta o reconhecimento deste grupo social como pessoas capacitadas a produzir e pertencer a sociedade em geral. E, ao mesmo tempo em que aponta a lacuna exposta pelo poder público, o agir pastoral sinaliza alternativa para o reconhecimento de pessoas que moram na rua com parcerias entre entidades não governamentais e movimentos sociais, como o MST, sendo assim uma via de reinserção social, além da promoção de Fóruns para a criação de medidas públicas com participação direta de pessoas que vivem na rua e albergues da cidade de São Paulo. Portanto, verifica-se uma práxis pastoral fundamentada por uma responsabilidade social dinamizada pela prática de parceria participativa que envolva as diversas esferas sociais para efetivação concreta dos direitos sociais da pessoa em situação de rua que vive em áreas urbana como a Cidade de São Paulo.
