Abundance and seasonality of Diptera (Insecta) in a poultry house in the northeast region of the state of Sao Paulo, Brazil

Modem production systems accommodate broody hens in high densities, leading to the accumulation of excrement under the cages. This substrate is excellent for the development of sinantropic flies. Thus, the accomplishment of surveys in these places becomes essential, in order to plan better strategies of control. The present work aimed at studying the entornofauna and the seasonality of the species of dipterous present in the Crisdan poultry house located in the Municipality of Sao Joao da Boa Vista, the State of Sao Paulo, Brazil. In the period of January of 2001 to December of 2002, 1,012,595 flies were captured using the ""jug-trap"". The species were identified: Drosophi-la repleta (Wollaston, 1858), Musca domestica (Linnaeus, 1758), Ophyra spp., Hennetria illucens (Linnaeus, 1758), Fannia canicularis (Linnaeus, 1761), Chrysomya megacephala (Fabricius, 1794), and Sepsidae. More frequently D. repleta and M. domestica had added 99.47% of the dipterous. Increased rainfall and the collection months influenced the sampling of dipterous (P < 0.05). Drosophila repleta was the most abundant species, representing 91% of all captured flies. However, this diptera did not develop at the surveyed site since immatures were not captured therein.

The competing roles of extensional viscosity and normal stress differences in complex flows of elastic liquids

In various attempts to relate the behaviour of highly-elastic liquids in complex flows to their rheometrical behaviour, obvious candidates for study have been the variation of shear viscosity with shear rate, the two normal stress differences N(1) and N(2) especially N(1), and the extensional viscosity eta(E). In this paper, we shall be mainly interested in `constant-viscosity` Boger fluids, and, accordingly, we shall limit attention to N(1) and eta(E). We shall concentrate on two important flows - axisymmetric contraction flow and ""splashing"" (particularly that which arises when a liquid drop falls onto the free Surface of the same liquid). Modem numerical techniques are employed to provide the theoretical predictions. It is shown that the two obvious manifestations of viscoelastic rheometrical behaviour can sometimes be opposing influences in determining flow characteristics. Specifically, in an axisymmetric contraction flow, high eta(E) , can retard the flow, whereas high N(1) can have the opposite effect. In the splashing experiment, high eta(E) can certainly reduce the height of the so-called Worthington jet, thus confirming some early suggestions, but, again, other rheometrical influences can also have a role to play and the overall picture may not be as clear as it was once envisaged.

Wallace lines in eastern Gondwana : palaeobiogeography of Australasian permian brachipoda

The present Australian continent was a major component of the north eastern peninsula of Gondwana, itself the southern region of Pangaea, during the Permian period. Surrounding what is now Australia, were additional elements of north eastern Gondwana that are now incorporated into the tectonically complex regions of New Zealand, New Caledonia, the island of New Guinea, Timor, south east Asia, the Himalaya and southern Tibet. India was to the west and south west and Antarctica to the south. Marine water temperatures ranged from cold to temperate and tropical as Permian global climates ameliorated, global surface ocean circulation systems warmed, and due to rifting and northward drifting of some terranes.

Provincialism of global marine faunas was pronounced during the Permian and hence refined biostratigraphical correlations are often fraught with difficulty. The 'middle' Permian stratotypes approved by the International Subcommission on the Permian System have little direct relevance to correlations within the Gondwanan Region at the level of operational biostratigraphical zonal schemes. Brachiopoda are a dominant marine benthonic faunal element of Permian Gondwanan faunas and they provide refined correlations between marine basins within a specific faunal province. Modem faunal provinces are recognised by the distribution patterns of species and genera belonging to a single family or superfamily such as the Papilionoidea within the Insecta. This review provides an example from Permian Brachiopoda, using the distribution data of genera and subgenera of the superfamily Ingelarelloidea, in order to demonstrate the ability to define provinces and their 'Wallace lines' of demarcation between provinces in the geological past.

Bacterial lessons on organelle division

Mitochondria and chloroplasts arose from bacterial endosymbionts about a billion years ago. This ancestry is now showing us how these organelles divide in modem cells.

Longitudinal study of computer usage in flexible engineering education

A longitudinal analysis of computer usage by commencing students in Deakin University's undergraduate engineering and technology programs over the period 1998 to 2001 revealed that; access to computers was at high levels; mean computer usage for off campus students had not changed significantly, but had risen significantly for on campus students; while access to the Internet / WWW had not increased significantly, reported regular use of the Internet / WWW had risen significantly; while most students continued to report their source of Internet / WWW access as either home or university, the proportion reporting home as their source of access had risen significantly; and the reported regular use of email rose significantly. Other results are also presented.

These results imply that commencing engineering and technology students are well placed to adopt online delivery and support of teaching and learning. However, while it might now be reasonable to assume that all students have access to computers and the Internet, the experiences of on campus students in computer laboratories with broadband network access will be different from off campus students accessing the Internet via a dialup modem connection. A small proportion of commencing students were unaware of the computing facilities provided by the university; an orientation program covering computing facilities and services would benefit all commencing students.

Transitional labour markets : a social investment and risk mitigation strategy for social policy

Drawing on transitional labor market (TLM) theory, this introductory chapter highlights major themes, overviews the contributions to this volume and suggests a future agenda for policy makers. The focus of applied research projects has been the impact of post-modem social transformations on systems of social protection, looking through the lens of the labor market and shifts in household and family structure. The Transitional Labor Market project uses the TLM model as a means of developing new thinking on how flexibility and innovation might be paired with social investment and new forms of social protection. TLM theory emphasizes the importance of institutions and of the links between different institutions which frequently operate as policy silos, rather than integrated systems to buffer risks and support capability and enhance employability. The great advantage of the TLM model is that it draws attention to the right places for strategic reform. It does not offer a standard set of institutions to facilitate transitions however.

What is the value of the arts?

In an age of globalisation, economic restructuring and rampant consumption, the "cultural industries" have come to be viewed as offering a source of social and economic salvation to declining towns, cities and regions. However, it is far from clear to what extent the arts, media and related tourism create employment, wealth, capital and community cohesion. What then is the value of the cultural industries and what concepts can be deployed to answer this question? This paper will report on one effort to devise a theoretical framework to assess the value of the cultural industries in one small Australian city. Drawing on Marxism, Pierre Boudieu and post-modem theory, it will develop a particular concept of "cultural capital" for use in quantifying and qualifying the socio-economic contribution of the cultural industries in Geelong, Victoria. It will argue that by linking Marx to Bourdieu around reformulated notions of "value" and "cultural capital", a theoretically rigorous framework can be distilled to assess and argue for the value of the arts. Such a concept has particular relevance and implications for arts managers.

Globalizing heritage: world heritage as a manifestation of modernism and the challenge from the periphery

Government efforts to protect monuments and sites of cultural heritage value have gone on for many centuries. The distinctive new chapter that
the 20th Century brought to cultural heritage protection was the establishment of a globalized effort over and above the work of nation states, This led to a new cultural heritage bureaucracy at the international level, the development of new sets of 'universal' standards, and a new set of places deemed to be of world heritage significance, All of this was done in the spirit of goodwill and optimism that infused the modem movement and that made possible the establishment of the so-called Bretton Woods organizations such as the United Nations as well as the parallel organizations specifically dealing with Cultural Heritage - UNESCO, ICOMOS, ICOM and ICCROM, In recent decades cultural relativists have challenged the drive towards uniformity implicit in the global activities of the modernist organizations, and various parts of the periphery have reacted against aspects of the global cultural heritage approach, The Venice Charter is no longer regarded as the single, universal way to conserve heritage places. It has been replaced or supplemented in large parts of the world by alternatives and modifications such as the Nara Document and Burra Charter. If it is no longer acceptable to provide a universal answer to the question of how do we identify and save heritage, the challenge of the 21st Century is to make the most of the complexity of standards that now exists.

Mlearning for India : any potential?

The trend towards mLearning is attributed to the growth of knowledge based societies (UNESC0,2005). In this paper, we examine if there is a case for mLearning in India, a developing nation with certain unique contributory factors such as rapid diffusion of mobile communication technologies negating the need for fixed line infrastructure; and the rising demand for flexible learning approaches by the eager, upwardly mobile, middle class population. Our research is informed by learning theory of constructivism that seems to underlie flexible adult learning in modem contexts. A speculative ongoing debate is examined through the lens of critical discourse analysis, to present an outlook for India. We open a launching platform for empirical work in India that would enable building of relevant models by extrapolating findings from this initial research. More significantly, the stakeholders in mLearning such as mobile technology/service providers, education providers and organisations that foster staff development in particular may be beneficiaries from the findings of this preliminary research.

Postmodernist theory and its relationship to tourism research

This article highlights the theoretical notion of Postmodernism and attempts to place Tourism research into the postmodernism frame of reference. This is achieved by a brief description of the theory and further development in section two which reviews the challenges of postmodernism to research in the tourism field. There is then an endeavour to intertwine the constructs of postmodernist theory and to illustrate how it can relate to the tourism industry and in particular contemporary tourism. Indeed, we argue that even though a number of authors have begun to chart the sociological dimensions of post-modem tourism they have done so without highlighting the definitions and structure of postmodernist theory. Examples are given in order to support the theoretical approach to research which we suggest in this paper and every effort is undertaken in order to argue that postmodernist research in tourism can be beneficial and fruitful tor future directions. Consequently this article attempts to dispel some of the widespread bemusement concerning post-modem theories and post-modern tourism by reviewing some of the recent developments in the area and suggesting further research.

You Shall Have No Other Gods Before Me: Covenant in Faith and History

In this paper I have attempted to explore "covenant" in faith and history, as it extends throughout the entire framework of the Bible and the entire history of the people who produced it. With such a monstrous topic, a comprehensive analysis of the material could take a lifetime to do it justice. Therefore, I have taken a very specific approach to the material in order to investigate the evolution of covenant from the Hebrew Bible (Old Testament) to the Christian Scriptures (New Testament). I have made every effort to approach this thesis as a text-based, non-doctrinal discussion. However, having my own religious convictions, it has, at times, been difficult to recognize and escape my biases. Nevertheless, I am confident that this final product is, for the most part, objective and free from dogmatism. Of course, I have brought my own perspective and understanding to the material, which may be different from the reader's, so there may be matters of interpretation on which we differ, but c 'est fa vie in the world of religious dialogue. The structure of this paper is symmetrical: Part I examines the traditions of the Torah and the Prophets; Part II, the Gospels and Paul's letters. I have balanced the Old Testament against the New Testament (the Torah against the Gospels; the Prophets against Paul) in order to give approximately equal weight to the two traditions, and establish a sense of parallelism in the structure of my overall work. A word should also be said about three matters of style. First, instead of the customary Christian designation of time as B.C. or A.D., I have opted to use the more modem B.C.E. (Before the Common Era) and C.E. (Common Era) notations. This more recent system is less traditional; however, more acceptable in academic and, certainly, more appropriate for a non-doctrinal discussion. Second, in the body of this paper I have chosen to highlight several texts using a variety of colors. This highlighting serves (1) to call the reader's attention to specific passages, and (2) to compare the language and imagery of similar texts. All highlighting has been added to the texts at my own discretion. Finally, the divine name, traditionally vocalized as "Yahweh," is a verbal form of the Hebrew "to be," and means, approximately, "I am who I am." This name was considered too holy to pronounce by the ancient Israelites, and, the word adonai ("My LORD") was used in its stead. In respect of this tradition, I have left the divine name in its original Hebrew form. Accordingly, should be read as "the LORD" throughout this paper. All Hebrew and Greek translations, where they occur, are my own. The Greek translations are based on the New Revised Standard Version (NRSV) of the Bible.

Intent and Method: A Study of Female Characters in Aeschylean and Euripidean Drama

Aeschylus and Euripides used tragic female characters to help fulfill the purpose of religious celebration and to achieve the motivation of public reaction. The playwrights, revising myths about tragic woman and redefining the Greek definition of appropriate femininity, supported or questioned the very customs which they changed. Originally composed as part of a religious festival for Dionysus, the god of wine, revelry and fertility, the tragedies of Aeschylus and Euripides were evaluated by Aristotle. He favored Aeschylus over Euripides, but it appears as if his stipulations for tragic characterization do not apply to Aeschylean and Euripidean women. Modem critics question both Aristotle's analysis in the Poetics as well as the tragedies which he evaluated. As part of the assessment of Aeschylus, the character of the Persian Queen, Atossa, appears as a conradiction the images that Greeks maintain of non-Greeks. The Persians is discussed in relation to modem criticisms and as on its function as a warning against radical changes in Athenian domestic life. The Oresteia, a trilogy, also charts the importance of an atypical woman in Aeschylean tragedy, and how this role, Clytaemnestra, represents an extreme example of the natural and necessary evolution of families, households and kingdoms. In contrast to Aeschylus' plea to retain nomoi (traditional custom and law), EUripides' tragedy, the Medea, demonstrates the importance of a family and a country to provide security, especially for women. Medea's abandonment by Jason and subsequent desperation drives her to commit murder in the hope of revenge. Ultimately, Euripides advocates changes in social convention away from the alienation of non-Greek, non-citizens, and females. Euripides is, unfortunately, tagged a misogynist by some in this tragedy and another example-the Hippolytus. Euripides' Phaedra becomes entangled in a scheme of divine vengeance and ultimately commits suicide in an attempt to avoid societal shame. Far from treatises of hate, Euripidean women take advantage of the little power they possess within a constrictive social system. While both Aeschylus and Euripides revise customary images and expectations of women in the context of religiously-motivated drama, one playwright intends to maintain civic order and the other intends to challenge the secular norm.

E-creativity: investigating computer-supported creativity

A fusion of the power of modem information and communication technology with the potential of human creativity provides an important and interesting area for research. In this paper, we outline this general research area that we term ecreativity. In particular, we describe our own focus of interest that we label computer supported creativity and the design of creativity support systems. As this is a largely uncharted territory, further research is of vital importance. We describe our research approach in this area and illustrate this with extracts from a case study of an artist who makes extensive and novel use of information technology in her creation of paintings.

Valuing creativity in technology education

When he was only twelve, Peter Jackson (director of The Lord of the Rings trilogy) cut fur strips from his mother's stole, and using wire he made a 20 cm model of King Kong. After a long incubation period for his ideas, he devised a modem version of the film King Kong. Research shows that the generation of new ideas (generative mental state) cannot exist at the same time as the non-generative/analytical mental state. This research has implications for technology educators who value creativity. We explored how an incubation period of non-focused thinking affected children's creative ideas for their technological products. Five teachers and 117 children from primary schools in a Victorian regional city and a semirural village participated in the study. The teachers factored in an incubation period that allowed time for the children's attention to wander in a relaxed and uncompetitive environment. We analyzed transcripts of teacher interviews and the children's written evaluations and drawings. We found a correlation between the incubation of ideas and the degree of creativity exhibited by the children. This key finding suggests that teachers of technology should take the incubation period into account in order to enhance creativity in the children's technology designs.

A life cycle inventory of aluminium die casting

As part of an ongoing project, a life cycle inventory (LCI) of aluminium high pressure die casting (HPDC) has been collected. This has been conducted from the view of an individual product and also the entire process. The objective of the study was to analyse the process and suggest changes to reduce environmental impacts. One modem aluminium high pressure die casting plant located in Victoria, Australia was evaluated and modelled. Site specific data on energy and materials was gathered and the process was modelled using a typical automotive component. The paper also presents our experience and methodology used in this inventory data collection process from the real industry for LCA purposes. The inventory data collected itself reveals that the HPDC process is energy intensive and as such the major emissions were from the use of natural gas fired furnaces and from the brown coal derived electricity. It is also found the large environmental benefits of using secondary aluminium over primary aluminium in the HPDC process. A detailed LCA is being cal1ied out based on the inventory obtained.
