Molecular characterization of nitrate reductase gene and its expression in the marine red alga Gracilaria tenuistipitata (Rhodophyta)

The enzyme nitrate reductase (NR) responsible for the conversion of nitrate to nitrite is considered to be the rate-limiting step in nitrogen assimilation. The economically important marine macroalga Gracilaria tenuistipitata presents a circadian oscillation in NR protein content and activity. In order to identify if the regulation of NR in G. tenuistipitata happens at transcriptional levels, the NR cDNA and gene were sequenced and the NR mRNA expression was studied. Analysis of the sequenced gene revealed absence of introns which is unusual for NR genes. The transcriptional profiling revealed a circadian rhythm for NR; furthermore, a rhythm was observed in constant light condition, suggesting a possible regulation by the biological clock at the mRNA levels for NR in G. tenuistipitata.

Do Different Models of Integration Affect Actual Integration? The Cases of France and Great Britain Revisited

Britain and France adapted two different integration models, namely assimilationist and multiculturalism to integrate their immigrants. These two big models of integration have distinctive characteristics to integrate immigrants. There is a general claim that multiculturalism model is the best for integrating immigrants in terms of actual integration, however, some argue the opposite, that French assimilationist model is ‘better off.’ This study examines these controversial claims by looking at the level to which immigrants are integrated in economic, social, political, cultural dimensions of integration and attitudes towards immigrants in Britain and France. Within a given theoretical framework, this study compares the overall competency level of immigrants’ integration in terms of actual integration between British multiculturalism model and French assimilationist model and validate that both these two big models of integration have reached a comparable level of integration and they do not have any decisive impact on actual integration.

Immigration, security and the public debate on US language policy : a critical discourse analysis of language attitudes in the United States of America

The narrative of the United States is of a "nation of immigrants" in which the language shift patterns of earlier ethnolinguistic groups have tended towards linguistic assimilation through English. In recent years, however, changes in the demographic landscape and language maintenance by non-English speaking immigrants, particularly Hispanics, have been perceived as threats and have led to calls for an official English language policy.This thesis aims to contribute to the study of language policy making from a societal security perspective as expressed in attitudes regarding language and identity originating in the daily interaction between language groups. The focus is on the role of language and American identity in relation to immigration. The study takes an interdisciplinary approach combining language policy studies, security theory, and critical discourse analysis. The material consists of articles collected from four newspapers, namely USA Today, The New York Times, Los Angeles Times, and San Francisco Chronicle between April 2006 and December 2007.Two discourse types are evident from the analysis namely Loyalty and Efficiency. The former is mainly marked by concerns of national identity and contains speech acts of security related to language shift, choice and English for unity. Immigrants are represented as dehumanised, and harmful. Immigration is given as sovereignty-related, racial, and as war. The discourse type of Efficiency is mainly instrumental and contains speech acts of security related to cost, provision of services, health and safety, and social mobility. Immigrants are further represented as a labour resource. These discourse types reflect how the construction of the linguistic 'we' is expected to be maintained. Loyalty is triggered by arguments that the collective identity is threatened and is itself used in reproducing the collective 'we' through hegemonic expressions of monolingualism in the public space and semi-public space. The denigration of immigrants is used as a tool for enhancing societal security through solidarity and as a possible justification for the denial of minority rights. Also, although language acquisition patterns still follow the historical trend of language shift, factors indicating cultural separateness such as the appearance of speech communities or the use of minority languages in the public space and semi-public space have led to manifestations of intolerance. Examples of discrimination and prejudice towards minority groups indicate that the perception of worth of a shared language differs from the actual worth of dominant language acquisition for integration purposes. The study further indicates that the efficient working of the free market by using minority languages to sell services or buy labour is perceived as conflicting with nation-building notions since it may create separately functioning sub-communities with a new cultural capital recognised as legitimate competence. The discourse types mainly represent securitising moves constructing existential threats. The perception of threat and ideas of national belonging are primarily based on a zero-sum notion favouring monolingualism. Further, the identity of the immigrant individual is seen as dynamic and adaptable to assimilationist measures whereas the identity of the state and its members are perceived as static. Also, the study shows that debates concerning language status are linked to extra-linguistic matters. To conclude, policy makers in the US need to consider the relationship between four factors, namely societal security based on collective identity, individual/human security, human rights, and a changing linguistic demography, for proposed language intervention measures to be successful.

Hårda nypor för ett mjukt samhälle? : Om medialisering och rasifiering i utspelspolitikens Sverige

Toughness for a soft society? On medialisation, racialisation and the politics of spin in Sweden In recent years, issues concerning the future of “multicultural Sweden” have become a salient feature in Swedish politics. One important actor in recent years’ debates about the problems confronting “multicultural Sweden” is the Swedish Liberal Party. Since the general election of 2002, the party has gained both publicity and electoral support by focusing the question of “integration of immigrants” in terms of assimilation and intensified demands aimed at the “immigrant Others”. In this article, the party’s recent developments in the area of integration policy is analysed within the framework of two general processes in contemporary politics, the politics of racialisation and the medialisation of politics. The party’s successful interventions in the area of integration policy are built on an intimate as well as complex interplay between racialisation and medialisation. The agenda articulated by the party, further, has several similarities with the agenda of “authoritarian populist” movements throughout Europe.

Development of on-line courses focusing on quality

The purpose of this paper is to show by which means quality in on-line education is achieved at Dalarna University. As a leading provider of online university courses in northern Europe, both in terms of number of students conducting their studies entirely on-line compared to the whole student body, (approximately 70% on-line students all subjects included), Dalarna University has acquired de facto extensive practical experience in the field of information technologies related to distance education. It has been deemed essential, to ensure that the quality of teaching reflects the principles governing the assessment of learning so that on-line education is deemed as comparative to campus education, both from a legal and cognitive point-of-view. Dalarna University began on-line courses in 2002 and it soon became clear that the interaction between the teacher and the student should make its mark in all stages of the learning process in order to both maintain the learners' motivation and ensure the assimilation of knowledge. We will illustrate these aspects by giving examples of what has been done in the recent years in on-line teaching of languages. As this method of teaching is not limited to learning basic language skills, but also to the study of literature, social issues and the language system of the various cultures, our presentation will offer a broad range of areas where the principles of quality in education are provided on a daily basis.

A displaced Britishness: Welsh Patagonians in Canada and Australia

This paper focuses on a unique group of British emigrants in their double migration experience from Wales to Patagonia in the second half of the nineteenth century and thence to Canada or Australia in the early twentieth. The history of the Welsh Patagonian settlements in the Chubut Valley of Argentina and the Andes foothills has been extensively documented. Less is known about the two subsequent migrations from Patagonia to Canada in 1902, and from Patagonia to Australia between 1910 and 1915. What distinguishes these movements is that, in each case, the settlers migrated as a group and placed a high priority on taking up adjoining land. In their three adopted countries they established discrete Welsh communities, some more enduring than others.

There is a general consensus that the initial move from Wales to Patagonia in 1865 was for nationalistic, cultural and linguistic reasons but for those who followed later, economic motives were more common. By the time of the migration from Patagonia to Canada in 1902, there was no illusion that Welsh nationalism could be preserved intact or autonomy guaranteed. Historians dispute the primary motivation for this particular move, some arguing that socio-economic and political factors in Patagonia were paramount, others that it resulted from inducements and political manoeuvrings from Canada and Great Britain. What is clear is the desire of the settlers to return to a country 'under a British flag'.

This paper addresses these issues relating to the Welsh Patagonian migration to Canada in the context of a comparison with the migration to Australia some years later. Such a comparative analysis has not previously been undertaken. Notions of identity and an erstwhile ‘Britishness’ are explored, in terms of the migrant’s sense of self and the political implications of citizenship, military service, reception and assimilation in the
host societies.

Exploration of a first year university multimedia module on field geology

As part of the teaching programme within a first year university unit on the earth’s physical systems, a ‘virtual reality’ field trip has been developed to support field studies relating to geological materials and landscape history. This module aims to increase student understanding of the use of geological features in the evaluation of geological / landscape history. The module has various applications in the curriculum. For students attending a weekend excursion, the module is available as an adjunct to actual field studies and can be used by students as either a digital pre-lab or as an excursion review tutorial. For students not attending a weekend excursion (i.e. off campus students), it is used as a digital ‘virtual reality’ substitute for field site inspection. The module has simple linked interactive and dynamic image base digital media that provide a framework in which the geology and landscape history of excursion sites can be explored. This module is delivered as a website via CD, but can also be integrated with the 'online interface' for this unit via a QuickTime reference movie loaded inside a relevant 'Deakin (University) Studies Online’ web page. The latter strategy enables assimilation of large multimedia files into online teaching formats

The commitment of public sector Sweden to codes of ethics

This article examines the results of a study conducted of the top 100 public sector units in Sweden. These units are comprised of entities of government, municipalities, and county councils. The aim of the study was to examine and describe the commitment to codes of ethics in these Swedish public sector units. This article reports on the responses of those public sector units that possessed a code of ethics. The construct of commitment was measured by a consideration of the inputs, objectives and outputs of the code across six areas. The commitment to codes of ethics has an interest for those involved in the public sector in Sweden and society in general. Most public sector units are in the early stages of development and assimilation into overall ethics policies in code artefacts. On a specific level there are customized codes of ethics that are not always documented in a generic artefact. Theoretical and managerial implications are provided. Furthermore, suggestions for further research are proposed.

Codes of ethics in corporate Sweden

Purpose – The purpose of the study is to examine and describe the use of codes of ethics in the top 100 companies operating in the Swedish corporate sector. This paper reports on the responses of those companies that possessed a code of ethics.

Design/methodology/approach – A three-stage research procedure was used. First, a questionnaire was sent to the public relations managers of the top 100 companies operating in the Swedish corporate sector (based on revenue). Companies were asked to answer up to 29 questions and to supply a copy of their code of ethics. The second stage involved content analysis of the codes of ethics supplied by survey respondents. The third stage involved a more detailed follow-up of a smaller group of firms that appeared to be close to best practice. Findings for Stage 1 of the research are reported in this paper. The areas of questioning were: how common are codes of ethics? Who was involved in the development of these codes? What are the reasons for the codes? How are they implemented? Do companies inform internal and external publics of the codes? What are the prescribed benefits of the codes?

Findings – It would appear that business ethics has only recently become a topic of interest in corporate Sweden and that many companies are in the early stages of code development and assimilation into company policies. The incidence of codes in the population (of 100) suggested by this survey (56 per cent) is lower than a US study finding (in 1995) that over 84 per cent of comparable US companies had codes of ethics. It would appear that Sweden today lags behind the US situation of 1995. When one investigates the special measures to support the inculcation of ethical values at the organizational level, there appears to be some shortfall. The supporting measures of ethics committees, ethics training committees, ethics training, ombudsman, an ethical audit and procedures to protect whistleblowers appear to be under-utilized in companies that possess codes. This lack of utilization tends to suggest that companies in Sweden, as yet, either have not developed a high commitment to supporting business ethics in their corporations, or they may have developed other methods to support their codes in their organizations that they view are as beneficial as the traditional methods practised in other western industrial democracies.

Research limitations/implications – This research was limited to internal ethical expectations. The commitment to business ethics is usually explored in terms of internal ethical expectations, but the simultaneous consideration of the external ethical expectations in the marketplace (e.g. among suppliers and customers or other publics) is desirable. A dyadic approach considering a company's internal ethical expectations and the external ethical expectations of a company's business activities may give a more balanced and in-depth approach.

Practical implications – Evidence is now available to show that codes of ethics are well developed in many of Sweden's largest corporations: organizations that, from their responses, appear to see a diverse range of benefits in developing the area of business ethics. Companies are beginning to implement not only a code of ethics, but other complementary initiatives that reinforce the need for the culture of the organization to be ethical. Codes of ethics are perceived by organizations to have assisted them in their dealings in the marketplace and many companies use their ethical values to underpin their strategic planning process. It appears that many companies now see the formalisation of business ethics as an integral part of their commercial practices.

Originality/value – This study is the first one of its kind on codes of ethics in corporate Sweden. It will enable all sectors of Swedish business to benchmark their efforts against the major companies in the Swedish corporate sector.

'Research as dialogue' and cross cultural consultations : confronting relations of power

The 'rescuing' of Indigenous children (from their communities) through education, and the notions of assimilation associated with that, is an aspect of colonialism that has persisted into the so-called 'post-colonial' era. Recent national policy statements (eg. MCEETYA, 2000; NBEET, 1995) argue the importance of education/research that keeps the locus of control within the Aboriginal community as a means to further the goal of self determination and improve educational outcomes. In this paper, we report on the initial stage of a small empirical research project, Engaging Aboriginal Students In Education Through Community Empowerment.

'Research as dialogue' was a guiding principal and a primary aim was to listen actively to all key stake holders in the remote community setting, particularly to Indigenous parents, teachers and service providers, in order to identify current

strengths and concerns regarding the provision of culturally inclusive schooling; and then, to develop, on the basis of these consultations and in collaboration, community-based education projects that engage non-attending Aboriginal students.

In this paper, we critically analyse the difficulties as well as potential strengths of trying to form collaborative partnerships as researchers, across cultural differences and with diverse community groups. For example, what does 'acknowledging' very different cultural perspectives actually mean to/in this kind of research process? The ways in which relations of power amongst all parties are played out in/through such an approach is also opened up for scrutiny and further discussion.

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.

A systematic grounded approach to the development of complex interventions : The Australian WorkHealth Program – Arthritis as a case study

Despite demands for evidence-based research and practice, little attention has been given to systematic approaches to the development of complex interventions to tackle workplace health problems. This paper outlines an approach to the initial stages of a workplace program development which integrates health promotion and disease management. The approach commences with systematic and genuine processes of obtaining information from key stakeholders with broad experience of these interventions. This information is constructed into a program framework in which practice-based and research-informed elements are both valued. We used this approach to develop a workplace education program to reduce the onset and impact of a common chronic disease – osteoarthritis.

To gain information systematically at a national level, a structured concept mapping workshop with 47 participants from across Australia was undertaken. Participants were selected to maximise the whole-of-workplace perspective and included health education providers, academics, clinicians and policymakers. Participants generated statements in response to a seeding statement: Thinking as broadly as possible, what changes in education and support should occur in the workplace to help in the prevention and management of arthritis? Participants grouped the resulting statements into conceptually coherent groups and a computer program was used to generate a ‘cluster map’ along with a list of statements sorted according to cluster membership.

In combination with research-based evidence, the concept map informed the development of a program logic model incorporating the program's guiding principles, possible service providers, services, training modes, program elements and the causal processes by which participants might benefit. The program logic model components were further validated through research findings from diverse fields, including health education, coaching, organisational learning, workplace interventions, workforce development and osteoarthritis disability prevention.

In summary, wide and genuine consultation, concept mapping, and evidence-based program logic development were integrated to develop a whole-of-system complex intervention in which potential effectiveness and assimilation into the workplace for which optimised.

Displaced self : the impact of language-migration on self-identity

In this dissertation I explore the impact that language-migration has on Self-Identity. The thesis consists of two parts: a memoir The Strangeness of Freedom, and an exegesis. Each is intended to stand alone, but also to complement the other. In the memoir I draw on my personal recollections of my family's migrations across five countries (Czechoslovakia, West Germany, USA and Australia) and into three languages (Czech, German and English) in order to convey my particular experience of language migration. In the exegesis I analyse several memoirs written by other language migrants and examine what impact they believe migrating into a new language and culture had on their own Self-identity. I draw on postmodern and psychoanalytic theory to explore the nature of Self-Identity formation and why migrants, as well as non-migrants might experience a change in their Self-identity during the course of their lives. I attempt to tease out to what extent the change in Self-identity is a universal experience that results from living across time and moving from a known past into an unknown future, regardless of whether one physically migrates or not. I found that while language-migrants tend to describe a more intense disruption of their Self-Identity, non-migrants also experience such a disruption in their sense of Self, simply by living in a rapidly changing world. I propose that while changing locations and languages clearly disrupts the continuity we presume life entails, it is in fact the passage of time that distances us from our known past, including our familiar Self, even if we never physically or linguistically migrate.
