Food resources influencing the asexual reproductive cycle of coronate Scyphozoa

The study of the strobilation process, a feature unique in the class Scyphozoa, is an issue that helps understanding the patterns of asexual reproduction in sessile invertebrates. Many inducers of asexual reproduction are known for scyphozoans. However, the influence of food resources on the strobilation of Coronate Scyphozoa has never been tested. WO observed strobilation of a large number of polyps of Nausithoe aurea, from a wide sampling area along the South Atlantic coast of Brazil, through the administration of controlled number of hatched nauplii of Artemia franciscana under a previous tested starvation and feeding protocol. The number of strobilations between and within groups varied and the fate and shape of strobilation deviated from the biology reported in the original description. Artificial seawater was used to reduce the influence of dissolved organic matter as likely important alternative nourishment.

Prediction of dynamical, nonlinear, and unstable process behavior

Process scheduling techniques consider the current load situation to allocate computing resources. Those techniques make approximations such as the average of communication, processing, and memory access to improve the process scheduling, although processes may present different behaviors during their whole execution. They may start with high communication requirements and later just processing. By discovering how processes behave over time, we believe it is possible to improve the resource allocation. This has motivated this paper which adopts chaos theory concepts and nonlinear prediction techniques in order to model and predict process behavior. Results confirm the radial basis function technique which presents good predictions and also low processing demands show what is essential in a real distributed environment.

A new Home, far from Home : The assimilation process of women involved in intercultural marriages based on Internet meeting

The internet has revolutionized the way we socialize, and as a consequence the way to love. The new communication technologies have facilitated intercultural relationships. Nowadays family relations are one of the major factors in immigration to European countries. Family relations means persons who arrive as family dependents and in accordance with laws regulating family reunification. This thesis aims to apply the classical assimilation theory stated by Milton Gordon (1964), which formulates a series of assimilation stages through which an individual must pass in order to be completely assimilated. In accordance with this theory, marriage is the final phase for a newcomer to fully incorporate into the host society. Thus, based on this presumption and other contemporary theories, the present study has analysed how women who get involved in intercultural marriages based on internet meeting experience these assimilation stages and evaluated the resources used by respondents to incorporate themselves into Swedish society.The main goal of the study was to determine if jumping to the last stage of assimilation does assure the incorporation in the social or/and labour spheres and the findings demonstrate that even though husbands are a valuable resource for assimilation, several cultural issues in Swedish society make it difficult to assure success for the newcomers.On the other hand, Sweden is a country with a strong national sentiment and the assimilation of immigrants still is an important issue to deal with. The Swedish Integration Board has disappeared and major projects for integration have been left in the hands of the municipalities or the Migration Board, institutions that still do not know how to deal with this dilemma.

Organizing forms in change management: the role of structures, process and boundaries in a longitudinal case analysis

This paper examines change management at William Angliss Institute of Technical and Further Education (TAFE) against the three organizational dimensions of structures, processes and boundaries identified by the INNFORM Study. Its experience confirms that even when an organization adopts a systemic approach and implements change across each design dimension, optimal performance benefits depend on mutually reinforcing and complementary changes. Furthermore, improvement to processes, particularly communications and human resources practices, plays a pivotal role, as complementary change across all dimensions depends ultimately on the contribution and commitment of organization members. Case findings also highlight the need for ambidextrous forms of organizing that combine 'controllability' with 'responsiveness'. The conceptual notion of organizing dualities has been employed to provide a practical interpretation of the ostensibly competing imperatives implied by ambidexterity. This case explores the dualities that can be demonstrated for the INNFORM triumvirate of structures, processes and boundaries. The dualities interpretation emphasizes an acceptance of texture and the simultaneous presence of what are conventionally viewed as incompatible organizing forms. This was considered a useful conceptual vehicle in the analysis of a case study covering nearly ten years of serious change interventions, where one theoretical view can be misleading in understanding the subtleties and complexities of the actual changes that occurred.

Playing a critical role: experiential learning resources and analytical media studies in higher education

This article compares two Information and Communication Technologies (ICTs) used in the Faculty of Arts, Deakin University Australia, and investigates the relationships between technology, pedagogy and key issues in the teaching and practice of public relations, in a media studies context. The online role-play ‘Save Wallaby Forest’ and the e-simulation ‘PRessure Point! Getting Framed (GF), in their different ways, afford learning  environments with capabilities that present public relations and media students with opportunities to discover a critical consciousness, break out of naturalised world-views, and explore alternative approaches to organisational communication. Furthermore, they present students with complex ethical issues to investigate based around the idea that media industries are powerful discursive producers and reproducers of social norms, values and beliefs which in turn shape notions of identity and influence the formation of public opinion in society (Fairclough 1999; Habermas 1995). This article explores the intersections and differences between these distinct ICTs in their relationships to a constructivist learning approach and ethical questions about how public relations both produces and reproduces world views through practice. This interacting nexus – between technology, pedagogy and theme – is significant because “what happens in the learning process” relates to the learning outcome and therefore has the potential to develop holistic reflexivity in studies of public relations (Laurillard 2003, p.42).

Rules and resources: a structuration approach to understanding the coordination of childrens`s inpatient health care

Aim. This paper presents findings from a multi-method study exploring the process of care coordination in children's inpatient health care.

Background. Existing work on care coordination is typified by 'black-box' type studies that measure inputs to and outcomes of care coordination roles and practices, without addressing the process of coordination.

Method. Using questionnaires, interviews and observation to collect data in multiple sites in the United Kingdom and Denmark between 1999 and 2005, the study gathered the perceptions of staff and compared these with observed practice. Giddens' structuration theory was used to provide an analytical and explanatory framework.

Findings. Current care coordination practice is diverse and inconsistent. It involves a wide range of clinical and non-clinical staff, many of whom perceive a lack of clarity about who should perform specific coordination activities. Staff draw upon a wide range of different material and non-material resources in coordinating care, the use of which is governed by largely tacit and informal rules.

Conclusions. Care coordination can be usefully conceptualized as a 'structurated' process – one that is continually produced and reproduced by staff using rules and resources to 'instantiate' or bring about care coordination through action. Potentially negative implications of this are manifested in diversity and inconsistency in care coordination practice. However, positive aspects such as the opportunity this provides to tailor care to the needs of the individual patient can be realized.

Australia's regional forest agreement process: analysis of the potential and problems

The 1990s heralded a new era in forest policy in Australia with the introduction of The National Forest Policy Statement which provided a framework under which native forest resources would be protected whilst also permitting ecologically sustainable timber harvesting. However, the implementation of the statement through the Regional Forest Agreements by state governments appear to contradict the conditions of the policy. Political bias towards development imperatives in implementing RFAs is evident. Community involvement in RFAs has not been satisfactory for sustainable forest use and management, with ongoing dissatisfaction from some stakeholder groups. There is still increased demand for protection of what remains of the various forest reserves. Aboriginal issues have not been settled in line with the expectation of the policy. There are continuing conflicts between the Commonwealth Government and some state governments

Requirements engineering during global software development : some impediments to the requirements engineering process : a case study

Requirements engineering is not straightforward for any software development team. Developing software when team members are located in widely distributed geographic locations poses many challenges for developers, particularly during the requirements engineering phase. This paper reports on a case study concerning a large software development project that was completed in just seven months between users located in the UK and software developers from an international software house based in New Zealand. The case indicates that while “true” global requirements engineering may be desirable in achieving economy of resources, a “hybrid” structure of requirements engineering processes is more realistic so that lasting relationships with clients may be formed, and requirements engineering activities achieved. The main impediment to the process of requirements engineering during global software development, as recounted by the team members in this case, is communication. Communication issues may be further described in terms of four categories: distribution of the clients and the development team, distribution of the development team, cultural differences between the clients and the development team and cultural differences among the development team.

Mapping the information resources available to patients with colorectal cancer

The objectives of this study were to identify gaps in information provision along the colorectal cancer (CRC) treatment pathway as provided by health services within the North Eastern Metropolitan Integrated Cancer Service in Victoria Australia; to evaluate the information and recommend consistent, high quality health information resources; and to recommend strategies to improve delivery of patient information. A random sample of health professionals (n= 47) from various disciplines at eight health service sites participated in semi-structured interviews regarding the types of information they provided to CRC patients. Information items were mapped against a published CRC patient management framework and evaluated. A total of 193 information items were collected with 24 items specific to CRC. Gaps in information provision were evident in the community, at diagnosis, in clinics, when treatment was determined and when completed. The quality of information delivery to CRC patients across the public health sites was variable. Resources were often unavailable, out of date and inaccessible in other languages. Results indicate a need to improve health information availability and resource delivery to all CRC patients across different health services particularly at diagnosis and after treatment. Further research is required to determine patient preferences for information about CRC.

Partnerships and place : mobilising resources from outside

Partnerships facilitate sharing of resources and can create outcomes that are more than the sum of partners’ contributions. The concept of partnership has entered policy rhetoric and is urged as good practice, sometimes along with consideration of place. For example, Mears et al’s recent academic critique of health policy holds that modern health systems should have a sense of place and be partnership orientated, as well as being primary care based and pragmatic in adopting effective practice. It is easy to regard partnership as unequivocally a good thing, however this is a simplistic view that ignores issues such as power imbalances, self-seeking behaviour of partners and the often complex, resource intensive and sensitive process required to establish and sustain partnerships. Rural communities tend to have fewer resources available for the provision of services such as health and education than their metropolitan counterparts, and so could be expected to benefit from partnerships with outside services and resource providers. Factors such as distance and lack of power in many professional and political domains imply that rural communities are also more likely to encounter barriers in establishing and maintaining partnerships with metropolitan based partners.

There is a growing literature on the composition and outcomes of partnerships in a variety of contexts and settings, including rural place-based communities, but relatively little about the partnership process. Understanding this process is a key step in designing policy at the system level and in developing and maintaining partnerships at the grass roots level. This paper makes a contribution to this gap by presenting lessons from the analysis of rural-urban partnerships around health services for two rural Tasmanian communities.

Multiple strategy process migration

The future of computing lies with distributed systems, i.e. a network of workstations controlled by a modern distributed operating system. By supporting load balancing and parallel execution, the overall performance of a distributed system can be improved dramatically. Process migration, the act of moving a running process from a highly loaded machine to a lightly loaded machine, could be used to support load balancing, parallel execution, reliability etc. This thesis identifies the problems past process migration facilities have had and determines the possible differing strategies that can be used to resolve these problems. The result of this analysis has led to a new design philosophy. This philosophy requires the design of a process migration facility and the design of an operating system to be conducted in parallel. Modern distributed operating systems follow the microkernel and client/server paradigms. Applying these design paradigms, in conjunction with the requirements of both process migration and a distributed operating system, results in a system where each resource is controlled by a separate server process. However, a process is a complex resource composed of simple resources such as data structures, an address space and communication state. For this reason, a process migration facility does not directly migrate the resources of a process. Instead, it requests the appropriate servers to transfer the resources. This novel solution yields a modular, high performance facility that is easy to create, debug and maintain. Furthermore, the design easily incorporates providing multiple migration strategies. In order to verify the validity of this design, a process migration facility was developed and tested within RHODOS (ResearcH Oriented Distributed Operating System). RHODOS is a modern microkernel and client/server based distributed operating system. In RHODOS, a process is composed of at least three separate resources: process state - maintained by a process manager, address space - maintained by a memory manager and communication state - maintained by an InterProcess Communication Manager (IPCM). The RHODOS multiple strategy migration manager utilises the services of the process, memory and IPC Managers to migrate the resources of a process. Performance testing of this facility indicates that this design is as fast or better than existing systems which use faster hardware. Furthermore, by studying the results of the performance test ing, the conditions under which a particular strategy should be employed have been identified. This thesis also addresses heterogeneous process migration. The current trend is to have islands of homogeneous workstations amid a sea of heterogeneity. From this situation and the current literature on the topic, heterogeneous process migration can be seen as too inefficient for general use. Instead, only homogeneous workstations should be used for process migration. This implies a need to locate homogeneous workstations. Entities called traders, which store and disseminate knowledge about the resources of several workstations, should be used to provide resource discovery. Resource discovery will enable the detection of homogeneous workstations to which processes can be migrated.

Investigating the pedagogical process in physical education teacher education

The study investigated two main questions: the first focused on the factors that enabled and constrained student teachers' engagement of a socially critical pedagogy in physical education teacher education (PETE); the second centered on gaining insight into the usefulness of knowledgeability as a concept for analysing student teachers engagement of a socially critical pedagogy. At the time of writing this thesis empirical analyses of socially critical pedagogies in physical education were rare in the educational literature. The study provided an alternative way of analysing student teachers’ engagement of a socially critical pedagogy in PETE. Alternative in that it avoided recycling and reproducing the dualism between agency and structure (Aronowitz and Giroux, 1985) that is prevalent in much of the physical education literature. Conversational interviews were conducted with four student teachers and their teacher educators throughout the duration of a one-semester PETE unit in an Australian university. Observations were made of the lecture and practical sessions and a document analysis was conducted of all unit learning resources. The analytical frame used in the study was structuration theory (Giddens, 1979, 1984). This framework was useful because it gave primacy to the duality of structure which recognised ‘the structural properties of social systems are both the medium and outcome of practices that constitute those systems’ (Giddens, 1979, p.69). The pedagogical intentions of the teacher educator co-ordinating the PETE unit were to change the orientations of the student teachers towards primary school physical education by encouraging them to adopt different ‘lenses’ through which to examine pedagogical practices. These ‘lenses’ highlighted the questions central to those with socio-critical intentions, eg. power, social injustice and diversity. Data generated from conversations with, and observations of, the student teachers, indicated that the actualisation of the teacher educator's intentions were somewhat limited. Despite this, adopting structuration theory as the explanatory framework for the study proved generative at a number of levels. Broadly, structuration theory was useful because it highlighted the way that student teachers' engagement with a socially critical pedagogy is contingent upon particular (idiosyncratic) dialectics of agency and structure. Using the duality of structure as an analytical tool illustrated the way student teachers' were influenced by structural factors as well as the way these structural factors were in turn constituted by the action of the student teachers. Also, by utilising structuration theory as an explanatory framework, the concept of knowledgeability was identified as a useful concept for analysing student teachers' engagement with a socially critical pedagogy in PETE. What is more, the study highlighted the reflexivity of the self and social knowledge, both characteristics of late modernity, as being integral to the way the student teachers engaged with the socially critical pedagogy of EAE400. Not only did the study highlight the reflexivity of the self but it also provided insight into the reflexivity of social knowledge. Much of the socially critical work in physical education implicitly adopts a linear approach to change. Given the findings of the study it might be useful for future developments to consider change as circular. The thesis concludes by suggesting that given the reflexivity of social knowledge, socially critical perspectives might be more readily engaged if the PETE content was incorporated into student teachers existing knowledge frameworks rather than viewed as a replacement for such frameworks.

Using online environments to promote assessment as a learning enhancement process

The 21st century presents new challenges relating to the need for assessment to be more innovative, more responsive to students' needs, and more relevant and authentic. The characteristics of good assessment are well known and resources abound to assist academic staff to change their practices. Yet, at a time when the imperative for reconsidering practices has never been greater, it appears to be very difficult to bring about and maintain substantive change in assessment. This paper presents case studies that illustrate the way some academic staff have responded to the challenges. In particular, how the online environment can enhance learning through formative assessment is illustrated with four case studies. The paper outlines specific challenges faced in each case and  discusses issues that arose during development and delivery. It concludes by identifying some of the factors that helped to facilitate changes in assessment practices in these specific cases.
