Effects of starvation and water quality on the purging process of farmed Murray cod ( Maccullochella peelii peelii )

The aim of this study was to determine the effects of starvation and water quality during the purging process on the biometric parameters, fatty acids, and flavor volatiles of Murray cod farmed in a recirculation system. Market size Murray cod, at the end of the grow-out stage, were divided into eight treatments. The treatments were either fed/starved (F or S) and kept in clean water (CW: CWF2, CWS2, CWF4, and CWS4) or fed/starved and kept in recycled water (RW: RWF2, RWS2, RWF4, and RWS4) for either 2 or 4 weeks. Fish were sampled at 0, 2, and 4 week intervals. Food deprivation was responsible for a significant (P < 0.05) weight loss compared to that of fed treatments. The same was observed for the condition factor (K), hepatosomatic index (HSI), and dress-out percentage (DP). No significant changes were, however, observed in the visceral fat index (VFI). Saturated fatty acids (SFA) were highest in RWF4 and lowest in CWS4 (P < 0.05), while monounsaturated fatty acids (MUFA) were lowest in CWF4 (P < 0.05). Starvation did not affect the flavor volatile compounds, which were mainly affected by changes in water quality. Specifically, total aldehyde (% w/w) content was significantly (P < 0.05) affected by water quality, but the time of purging was not responsible for any noteworthy differences. This study was able to separate the effects of starvation and water quality, in the purging process, on the final eating quality of farmed market size Murray cod. It is concluded that because of the inevitable weight loss during starvation, Murray cod should be fed during the purging stage but kept in clean water and deprived of food only for the time necessary to empty the gastro-intestinal tract.

The process of change in offender rehabilitation programmes

Whilst the overall effectiveness of offender rehabilitation programmes in reducing recidivism is now well established, there has been less discussion of the reasons why rehabilitation programmes may be unsuccessful for some offenders. In this paper we suggest that models of change developed in counselling and psychotherapy may have utility in explaining how offender rehabilitation programmes bring about change, and argue that the dominance of cognitive-behavioural treatments in the rehabilitation field means that those offenders who have particularly low levels of problem awareness may be at increased risk of treatment failure. Understanding more about the mechanisms by which programmes help offenders to desist from offending is likely to lead to the development of more responsive and, ultimately, more effective programmes. Some suggestions for those involved in the delivery of offender rehabilitation programmes include: being mindful of the sequence of components of programmes, the development of preparation (or readiness) programmes and offering a broad suite of programmes to cater for different stages of problem awareness and assimilation among offenders.

English language reform and the process of democratic change

Malaysian society has and is undergoing considerable social, political, economic and educational change. Scholars point to the forces of globalization and the needs to be able to meet the challenges of globalization as the central driver of language policy. Commentators, academics and many in the general public have focused on the need for Malaysia to adapt to globalization and the importance of English to this process given the needs and characteristic of the knowledge economy. However, there appears to be less recognition of the way such a change in Malaysian language policy needs to be engaged in a dynamically shifting knowledge society and developing public sphere. Language is a social act and the debate over language and its place and role in society is therefore a debate over the nature and quality of social interaction. Debate over language is thus inherently political. Due to the growth and development of an interactive and engaged public sphere and knowledge society in Malaysia, there is a need to approach to the idea of engaging English that grasps the plurality and complexity of its role in the world. The political approach to engaging English in Malaysia needs to engage democratic deliberation in a society that is increasingly fragmented but also showing signs of developing an active public sphere not beholden to top down authority. Disagreement over language and the way the debate is theorized hides from view the possibility of points of consensus on the issue of English language and Malaysian education. Establishing overlapping consensus through public deliberation and consultation is a necessary precondition to effective language policy in contemporary Malaysia. Failure to understand this only leads to policy paralysis.

Experimental and numerical analysis of the deformed process of cracks/cavities

In this paper, the three-point bending tests of beams with a small single-edge crack are conducted to demonstrate the reliability and accuracy of the laser diffraction technique in detecting its deformation and evolution. As a comparison, the quasi-static analysis of the beam subjected to 3-point bending is further proceeded using the finite element method and the related results have been in good agreement with those from the tests.

Brennan torpedo, monorail and helicopter : a study of innovative activity in the process of forming three related military weapons

In the context of nineteenth-century British defence planning Actor-network theory is used to examine technological and social activity in the development and operation of a secret, successful military weapon, the Brennan torpedo. Also in two subsequent inventions the continuity and development of a core innovative concept, gyroscopy, is traced.

The role of support mechanisms in the process of identity transition of HIV-positive people

This study examines identity transit ion in HIV-positive people through their engagement with various support mechanisms. The findings demonstrate that identity transition is the result or how consumers rework, negotiate and transform their roles, actions, and cultural meanings through their consumption of sporting mechanisms.

The process of interpersonal perspective taking

Perspective taking, the main cognitive component of empathy, has a particularly important and complex role to play in the clinician-client relationship, particularly in mental health nursing. However, despite extensive investigation into the outcomes of this construct (e.g. sympathy, altruism), the process by which people take another's psychological point of view has received comparatively little attention. The purpose of this study was to investigate what the individual does when attempting to take the perspective of another person. The aims were to identify the specific strategies people used to accomplish this task, to consider how and why these strategies were chosen, and the relationship between the strategies and subsequent outcomes. Participants described an example of their own perspective-taking experience. Adopting an interpretive phenomenological approach, analysis resulted in the generation of several themes of direct relevance to both the perspective taking process and the wider empathic experience. Of particular importance were two superordinate themes, use of other-information and use of self-information. One significant subordinate theme (within use of selfinformation) to emerge was that of past experience, where the participant had experienced either (a) a similar role to that which they occupied in the present situation, or (b) a similar situation to that of the target person. Both of these experiences were determinants of how easy participants perceived the task of apprehending the target’s perspective. Within the wider empathic experience, themes included emotional manifestations (e.g. sympathy), as well as judgements of appropriate behaviours. Implications of findings when working in clinical and mental health settings are discussed.

Descriptive model of the offence process of women violent offenders : distal background variables

The literature indicates two areas of growing concern in regard to the perpetration of violence by women. One is that the incidence of violence perpetrated by women is increasing across jurisdictions. The other is that despite their growing numbers the knowledge and understanding of violent women has been greatly hindered by the general lack of empirical investigation of this population. The present study uses a grounded theory approach to develop a preliminary descriptive model of the offence process of women violent offenders. The women's violent offence model (WVOM) has four distinct levels or phases. The current article addresses the first of these in detail, consisting of the distal background variables. This phase of the model includes experiences of childhood and adolescence, providing preliminary insight into the more stable distal predispositional factors underlying women's violent offending.

Research and diabetes nursing. Part 2 : process of critical review

This article is the second in a six-part series addressing research and the DSN. Crirical review is a key aspect of research and evidencebased care and, therefore, of clinical and professional practice. Critical review is an analytical and reflective process that involves judging the quality of research publicarions and their relevance to practice. This article oudines key aspects of how to review publications and conference presentations, how critical review applies to clinical care, and how this process om help develop writing and critical thinking skills. Also addressed are the general aspects of critical review, and a list of further reading and useful websites is provided. Specific considerations for particular research methods such as quantitative, qualitative, evaluation studies and audits will be addressed in later articles in the series.
