Allozyme evidence for a new species of freshwater crayfish of the genus Cherax Erichson (Decapoda : Parastacidae) from the south-west of Western Australia

The marron, Cherax tenuimanus (Smith), is one of the most easily recognisable members of the freshwater crayfish genus Cherax. Since its description in 1912, the taxonomy of the species has not been in dispute, but recent genetic studies have demonstrated that the species is not homogenous and consists of two genetically distinct forms. One of these forms is widespread and exploited via aquaculture and the other is restricted to a single river system, the Margaret River. This paper presents allozyme data, collected over a 19-year period, which documents the introduction of the widespread form into the Margaret River and the subsequent reproductive interactions between the two forms. These data indicate minimal interbreeding between the two forms of marron and so justify their recognition as distinct species. As the original description of the marron was based on specimens collected from the Margaret River, the form native to this river retains the name C. tenuimanus and a new species, Cherax cainii Austin is described for the common, widespread form of marron. An additional outcome of this study is that C. tenuimanus has been rapidly displaced by the introduced C. cainii within the Margaret River. Consequently, urgent conservation measures are required to protect C. tenuimanus and prevent its possible extinction.

Land retirement: a biodiversity policy for the rangelands of Western N.S.W.

In this article we examine land retirement as a biodiversity policy option for the rangelands of Western NSW, a region seriously under-represented in biodiversity provision. We argue that the use of policies that rely on moral suasion, education and minimal costsharing will not yield the level of on-farm biodiversity provision demanded by society. Instead, a much greater commitment to the use of monetary incentives to induce the voluntary cooperation and production of biodiversity is required. The analysis explains the importance in policy design of determining transparent, meaningful and achievable objectives in delivering cost-effective environmental outcomes. We propose a land retirement
policy that rakes account of environmental, economic and political criteria. Finally, our land retirement proposal is supported quantitatively by benefit-cost analysis.

From empire to filmi: a fusion of western and Indian cultural practices in Australian music education

During the 19th and 20th centuries, Indian culture was represented in Australia as part of celebrations of the British Empire. Children were presented with stereotypic representations of Indian culture, which provide a snapshot of contemporary perceptions. Such representations were rarely authentic. By removing music from one culture and presenting it in the symbolic gestures of another we strip away much of its meaning. Encouragingly, contemporary popular culture can incorporate a fusion of western and Indian cultural practices, such as filmi (Hindi: `film song' or `Indian film music'). This article describes early imperialist understandings of Indian culture in Australian school music to contextualize recent attempts to engage with more authentic intercultural understandings. To assist teachers in the presentation of `other' musics, guidelines for the inclusion of authentic materials are offered. By selecting music that is already a fusion of cultures and musical styles, it becomes easier for western music educators to engage with the other.

Evidence for crossvergence in the perception of task and contextual performance : a study of western expatriates working in Thailand

The applicability of the Western model of task and contextual performance to the context of Thai and Western managers, professionals and consultants working together in Thailand is addressed in this research. The results show a clear difference in the factor structure of how Western and Thai managers perceive the importance of performance factors. Moreover, the task and contextual factor structure found for Western managers working in a Western culture did not hold for Westerners working within the Thai cultural environment. These findings provide evidence of adaptation by the Westerner to the Thai cultural environment, supporting the notion of crossvergence.

The development of biological objectives for streams in a single catchment: a case study on the catchment of western port bay, Victoria, Australia

Government environment protection policies for waterways have traditionally relied on water quality indicators and their objectives. In this paper we describe the development of biological objectives based on invertebrate indicators for inclusion in a government policy for the catchment of Western Port Bay, Victoria. The first step of defining segments (areas with streams in which the same objectives are applied) was problematic, requiring two different approaches, as follows. Site groups initially based on invertebrate community composition derived using multivariate techniques (ordination and classification) proved to be unsuitable for policy segments. Segment boundaries were subsequently defined using topographical (e.g. boundary of foothills and lowland plains), climate (e.g. rainfall) and land-use (e.g. urban) features. We used information and data from reference sites inside as well outside the catchment to derive specific biological objectives based on aquatic invertebrates for these segments. Objectives were specified for the following four indicators – number of invertebrate families, the SIGNAL index, the AUSRIVAS predictive model and the number of key families.

The inadequacy of Western media theory in third world internal conflicts : the case of military censorship in Sri Lanka

The literature of communication and conflict is long and deep. However, it has focused primarily on cross-border conflict in the northern hemisphere. Not much academic research has been done on intra-state conflicts in general or on Asian conflicts in particular. This research on the Sri Lankan separatist conflict contributes towards filling this void.Newspaper reports in three languages on Operation Jayasikurui (1997) as well as on the capture of Elephant Pass (2000) were analyzed by trained coders with high reliability. In-depth interviews were conducted with Sri Lankan journalists and military personnel who participated in these incidents. Triangulation sources include Sri Lanka Army materials and the Sri Lanka Government Gazette.

Results clearly show that despite stringent governmental regulations, censorship had no effect on these Sri Lankan newspapers, which employed unique cultural techniques to circumvent these restrictions. Despite their apparent divergent ethnic backgrounds, all newspaper samples are consensual in their depiction of the conflict all the time while managing to set different agendas for their individual readerships. Media regulations could not impose censorship as proposed by Western theoretical constructs. Results show no correspondence between media samples and imposition of government or military policy. The press enjoyed freedom to convey war information to the public and exhibited a distinct streak of social responsibility in their watchdog instincts.Dominant Western propaganda models and theoretical perspectives do not apply to the Sri Lankan context. Understanding the cultural dimensions is essential before theorizing on media behaviour. No particular theoretical framework from the literature could be used to make inferences. One further interesting finding suggested from this research: Internal conflict within the Asian region may have its own unique theoretical perspective. The study concludes by proposing an alternative model.

The inadequacy of Western media theory in third world internal conflicts : the case of military censorship in Sri Lanka

Research on media production and on media effects under military censorship has centred primarily on cross-border conflicts being waged by Western regimes. There is a noticeable void in understanding internal conflicts, particularly so within the Asian region. To help address this lacuna, we content-analyse Sri Lankan newspaper samples of two critical military campaigns within the Sri Lankan separatist conflict to gain insight into an Asian internal conflict within the context of military censorship and culture. We discover that supposedly stringent censorship regulations and the rules of the official communication systems have almost no effect on Sri Lankan newspapers, which demonstrate a unique talent to circumvent these strictures. During these bloody internal conflicts, the Sri Lankan press enjoyed freedom of expression, flaunted social responsibility and their watchdog instincts, and, most interestingly for us, demonstrated the failure of the Western propaganda model and other theoretical perspectives. The importance of understanding cultural dimensions before theorizing media behaviour in order to obtain a more rational understanding of the sociology of media is posited by this study. We conclude with discussion of a new model of media censorship which has more relevance in Asian internal conflicts.

Yagonia Roberts (brachiopoda : chonetidina) from the malimán formation, lower carboniferous of western Argentina : palaeobiogeographical implications

A new anoplid chonetid species, Yagonia furquei sp. nov., is described from the Lower Carboniferous (late Tournaisian–early Viséan) Malimán Formation of western Argentina. The associated temperate ‘Malimanian’ fauna is suggested to indicate an initial biotic segregation that took place in western Gondwana (southwestern South America), a palaeobiogeographic event that predated the late Viséan global cooling and associated major palaeolatitudinal biotic differentiation. Occurrences of Yagonia are here interpreted as evidence of a ‘south to north’ faunal migration pathway, here named the Austropanthalassic–Rheic oceanic corridor, established in western Gondwana during the late Early Carboniferous.

Acid drainage, limnology and bioremediation of western Victorian coal mine lakes

Rehabilitation of Alcoa's Anglesea open cut brown coal mine to a healthy lake has many environmental challenges. The study of regional acid drainage, limnology of Wenslydale Coal Mine Lake and passive bioremediation of acid mine water has shown that a healthy lake can be created.

Papers from Marrakech : a post-colonial reading of western women's travel writing in North Africa and the Middle East

This thesis takes the form of a collection of theoretical and fictional documents comprising a journal, letters and essays sent home to Australia by a woman travelling in Morocco. In different modes, these papers examine issues of colonialism, gender and desire in western women's travel writing about North Africa and the Middle East.

Investigation into the appropriacy of Western language teaching methods in Taiwan

The language learning preferences of EFL students are often assumed and not readily understood by foreign teachers. This study sought to determine the types of language learning classroom activities preferred by adult learners of English in Taiwan. Student responses were then compared with responses from native-speaking teachers of EFL.

Association of western and traditional diets with depression and anxiety in women

Objective: Key biological factors that influence the development of depression are modified by diet. This study examined the extent to which the high-prevalence mental disorders are related to habitual diet in 1,046 women ages 20–93 years randomly selected from the population.

Method: A diet quality score was derived from answers to a food frequency questionnaire, and a factor analysis identified habitual dietary patterns. The 12-item General Health Questionnaire (GHQ-12) was used to measure psychological symptoms, and a structured clinical interview was used to assess current depressive and anxiety disorders.

Results: After adjustments for age, socioeconomic status, education, and health behaviors, a "traditional" dietary pattern characterized by vegetables, fruit, meat, fish, and whole grains was associated with lower odds for major depression or dysthymia and for anxiety disorders. A "western" diet of processed or fried foods, refined grains, sugary products, and beer was associated with a higher GHQ-12 score. There was also an inverse association between diet quality score and GHQ-12 score that was not confounded by age, socioeconomic status, education, or other health behaviors.

Conclusions: These results demonstrate an association between habitual diet quality and the high-prevalence mental disorders, although reverse causality and confounding cannot be ruled out as explanations. Further prospective studies are warranted.

Understanding Chinese identity in international relations : a critique of Western approaches.

In international relations in the West, two main approaches to Chinese identity have emerged: the capability and the culture approaches. Though each takes a different view of China, they share common epistemological ground. positivism. This paper provides an overview of these two influential schools of thought and attempts to challenge their positivistic and ethnocentric assumptions about the identities of both China and the West. While they endeavour to make sense of China, particularly in the post-Cold War era, they fail to understand identity as a form of representation. From a critical perspective, both ’China’ and the ‘West’ are social constructs: each in part constitutes the other. The relationship between them is always relational and fluid. Posing Chinese identity in positivist terms is not only misleading analytically, but potentially dangerous in practice. It is important, therefore, that alternative critical approaches to the complexities of Chinese identity be further explored.
