Discovery of ultracompact dwarf galaxies in the Virgo Cluster

We have discovered nine ultracompact dwarf galaxies (UCDs) in the Virgo Cluster, extending samples of these objects outside the Fornax Cluster. Using the Two Degree Field (2dF) multifiber spectrograph on the Anglo-Australian Telescope, the new Virgo members were found among 1500 color-selected, starlike targets with 16: 0 < b(j) < 20.2 in a 2 degrees diameter field centered on M87 (NGC 4486). The newly found UCDs are comparable to the UCDs in the Fornax Cluster, with sizes less than or similar to 100 pc, -12.9 < M-B < -10.7, and exhibiting red absorption-line spectra, indicative of an older stellar population. The properties of these objects remain consistent with the tidal threshing model for the origin of UCDs from the surviving nuclei of nucleated dwarf elliptical galaxies disrupted in the cluster core but can also be explained as objects that were formed by mergers of star clusters created in galaxy interactions. The discovery that UCDs exist in Virgo shows that this galaxy type is probably a ubiquitous phenomenon in clusters of galaxies; coupled with their possible origin by tidal threshing, the UCD population is a potential indicator and probe of the formation history of a given cluster. We also describe one additional bright UCD with M-B = -12.0 in the core of the Fornax Cluster. We find no further UCDs in our Fornax Cluster Spectroscopic Survey down to bj 19.5 in two additional 2dF fields extending as far as 3 degrees from the center of the cluster. All six Fornax bright UCDs identified with 2dF lie within 0.degrees 5 (projected distance of 170 kpc) of the central elliptical galaxy NGC 1399.

Internationale Konjunkturverbunde

After conceptual clarification of international business cycle and a review of the literature, a new indicator is proposed. This indicator refers to two time series only and allows for an internationally comparable quantification of a country's position in the business cycle. We then calculate times series of this indicator for 30 countries from 1970-2000. After some plausibility checks, we refer to these series to test a number of hypotheses. Cross correlations reveal a high degree of interconnectedness. Moreover, the number of highly positive correlations has increased over time, whereas the number of low and moderate correlations has decreased. A principal components analysis yields a first component that can be interpreted as the world business cycle. The further components suggest the existence of a Scandinavian-Anglo-Saxon business cycle as well as of another, smaller group of Anglo-Saxon countries that move together. This finding is replicated by a hierarchical cluster analysis, which in addition suggests a closely integrated group of non-Scandinavian and non-English speaking European countries plus Japan and Israel. Furthermore, there is indication for some, albeit weak business cycle integration in Southeast Asia and in South America. The international business cycle is thus found to have a hierarchical structure.

Kinematics, substructure and luminosity-weighted dynamics of six nearby galaxy groups

We have redefined group membership of six southern galaxy groups in the local universe (mean cz < 2000 km s(-1)) based on new redshift measurements from our recently acquired Anglo-Australian Telescope 2dF spectra. For each group, we investigate member galaxy kinematics, substructure, luminosity functions and luminosity-weighted dynamics. Our calculations confirm that the group sizes, virial masses and luminosities cover the range expected for galaxy groups, except that the luminosity of NGC 4038 is boosted by the central starburst merger pair. We find that a combination of kinematical, substructural and dynamical techniques can reliably distinguish loose, unvirialized groups from compact, dynamically relaxed groups. Applying these techniques, we find that Dorado, NGC 4038 and NGC 4697 are unvirialized, whereas NGC 681, NGC 1400 and NGC 5084 are dynamically relaxed.

The 2dF-SDSS LRG and QSO (2SLAQ) luminous red galaxy survey

We present a spectroscopic survey of almost 15 000 candidate intermediate-redshift luminous red galaxies (LRGs) brighter than i = 19.8, observed with 2dF on the Anglo-Australian Telescope. The targets were selected photometrically from the Sloan Digital Sky Survey (SDSS) and lie along two narrow equatorial strips covering 180 deg(2). Reliable redshifts were obtained for 92 per cent of the targets and the selection is very efficient: over 90 per cent have 0.45 < z < 0.8. More than 80 per cent of the similar to 11 000 red galaxies have pure absorption-line spectra consistent with a passively evolving old stellar population. The redshift, photometric and spatial distributions of the LRGs are described. The 2SLAQ data will be released publicly from mid-2006, providing a powerful resource for observational cosmology and the study of galaxy evolution.

The large peculiar velocity of the cD galaxy in Abell 3653

We present a catalogue of galaxies in Abell 3653 from observations made with the 2-degree field (2dF) spectrograph at the Anglo-Australian Telescope. Of the 391 objects observed, we find 111 are bona fide members of Abell 3653. We show that the cluster has a velocity of cz= 32 214 +/- 83 km s(-1) (z= 0.10 738 +/- 0.00 027), with a velocity dispersion typical of rich, massive clusters of sigma(cz)= 880(-54)(+66). We find that the cD galaxy has a peculiar velocity of 683 +/- 96 km s(-1) in the cluster rest frame - some 7 sigma away from the mean cluster velocity, making it one of the largest and most significant peculiar velocities found for a cD galaxy to date. We investigate the cluster for signs of substructure, but do not find any significant groupings on any length scale. We consider the implications of our findings on cD formation theories.

Neurobiological alterations in the human alcoholic brain: effect of genotype

Long-term alcohol abuse by human subjects leads to selective brain damage that is restricted in extent and variable in severity. Within the cerebral cortex, neuronal loss is most marked in the superior frontal cortex and relatively mild in motor cortex. Cirrhotic alcoholics and subjects with alcohol-related Wernicke-Korsakoff syndrome show more severe and more extensive damage than do uncomplicated cases. Accumulating evidence suggests that the likelihood of developing alcohol dependency is associated with one or more genetic markers. In previous work we showed that GABAA receptor functionality, and the subunit isoform expression that underlies this, differed in region- and disease-specific ways between alcoholics and controls. By contrast, glutamate receptor (NMDA, KA, AMPA) differences were muted or absent. Here we asked if genotype differentiated the form, pharmacology, or expression of glutamate and GABA receptors in pathologically vulnerable and spared cortical regions, with a view to determining whether such subject factors might influence the severity of alcohol-induced brain damage. Cerebrocortical tissue was obtained at autopsy under informed, written consent from uncomplicated and alcoholic-cirrhotic Caucasian (predominantly Anglo-Celtic) cases, together with matched controls and cases with cirrhosis of non-alcoholic origin. All subjects had pathological confirmation of liver and brain diagnosis; none had been polydrug abusers. Samples were processed for synaptic membrane receptor binding, mRNA analysis by quantitative RT-PCR, and protein analysis by Western blot. Genotyping was performed by PCR methods, in the main using published primers. Several genetic markers differentiated between our alcoholic and control subjects, including the GABAA receptor 2 subunit (GABB2) gene ( 2 (3) 10.329, P 0.01), the dopamine D2 receptor B1 (DRD2B) allele ( 2 (3) 10.109, P 0.01) and a subset of the alcohol dehydrogenase-3 (ADH3) alleles ( 2 (2) 4.730, P 0.05). Although neither the type-2 glutamate transporter (EAAT2) nor the serotonin transporter (5HTT) genes were significantly associated with alcoholism, only EAAT2 heterozygotes showed a significant association between ADH3 genotype and alcoholism ( 2 (3) 7.475, P 0.05). Other interactions between genotypes were also observed. DRD2A, DRD2B, GABB2, EAAT2 and 5HTT genotypes did not divide alcoholic cases and controls on NMDA receptor parameters, although in combined subjects there was a significant DRD2B X Area Interaction with glutamateNMDA receptor efficacy (F(1,57) 4.67; P 0.05), measured as the extent of glutamate-enhanced MK801 binding. In contrast, there was a significant Case-group X ADH3 X Area Interaction with glutamateNMDA receptor efficacy (F(3,57) 2.97; P 0.05). When GABAA receptor subunit isoform expression was examined, significant Case-group X Genotype X Area X Isoform interactions were found for EAAT2 with subunit mRNA (F(1,37) 4.22; P0.05), for GABB2 with isoform protein (F(1,37) 5.69; P 0.05), and for DRD2B with isoform protein (F(2,34)5.69; P0.05). The results suggest that subjects’ genetic makeup may modulate the effectiveness of amino acid-mediated transmission in different cortical regions, and thereby influence neuronal vulnerability to excitotoxicity.

SARAH POULTON KALLEY (1825-1907): Professora, Missionária e Poetisa

Sarah Poulton Kalley é conhecida, em quase todos os segmentos do protestantismo do Brasil, devido à organização e compilação d e Salmos e Hinos, o mais antigo hinário protestante editado no vernáculo em nosso país. Seus hinos, ainda em uso em muitas igrejas, marcaram por mais de um século a teologia do protestantismo no Brasil. Apesar desta notoriedade, sua influência na gênese do protestantismo brasileiro nunca foi objeto de estudo. Assim, o objetivo desta pesquisa é resgatar e visibilizar áreas e estratégias de atuação que conferem a esta mulher um perfil de atuação relativamente autônomo. Contudo, centrada no estudo da trajetória intelectual e biográfica de um sujeito histórico, a investigação se defronta com um universo de personagens anônimos, envoltos numa complexa teia de relações, através das quais o protestantismo se insere no Brasil em um contexto especifico: huguenotes, puritanos, luddistas, famílias não-conformistas inglesas, líderes políticos e eclesiásticos, exilados madeirenses, brasileiros, portugueses, imigrantes alemães e, principalmente, a mulher protestante brasileira. A busca por informações sobre este universo relegado ao anonimato pela historiografia do protestantismo no Brasil, reve lou alguns documentos inéditos, inclusive um livro escrito por Sarah Poulton Kalley, em 1866: o A Alegria da Casa. Muito além do papel de esposa de um missionário e médico, Sarah Poulton Kalley emerge de uma rede de relações e práticas como professora, missionária e poetisa. Nestes três campos de atuação e através do desenvolvimento de múltiplos contatos e relacionamentos, procurava transformar e influenciar atitudes e crenças de seus interlocutores. Junto com a nova fé divulgava uma cosmovisão própria da cultura anglo-saxã, protestante e puritana, adaptando-a seletivamente ao universo cultural e social de seus interlocutores.(AU)

O PREGADOR SILENCIOSO: Ecumenismo no jornal Expositor Cristão (1886-1982)

O jornal Expositor Cristão, órgão oficial da Igreja Metodista no Brasil, nasceu em 1886, com uma proposta que se poderia chamar de ecumênica: seu primeiro nome, Methodista Catholico, revela o desejo de universalidade, confirmado pelo editorial de estréia. Seu criador, o missionário norte-americano John James Ransom, pretendia um veículo de orientação doutrinária que não fosse sectário, em consonância com a tradição wesleyana. Mas o Metodista Católico teve vida curta: em pouco mais de um ano passou a se chamar Expositor Cristão. O campo religioso brasileiro vivia, então, o período da controvérsia apologética, com a inserção do protestantismo de missão, de origem anglo-saxã, em contraposição ao catolicismo romano. O nome do recém-nascido jornal foi mais uma vítima dos embates. Este trabalho se dispôs a avaliar como o jornal tratou a questão do ecumenismo desde esse período até a entrada da Igreja Metodista no CONIC, Conselho Nacional de Igrejas Cristãs, no início da década de 1980. A pesquisa constatou que o anticatolicismo arraigado no metodismo brasileiro em seus primórdios jamais desapareceu por completo. Notou também que o metodismo não esteve imune aos conflitos interdenominacionais existentes no próprio meio evangélico. Em que pese o reconhecido pioneirismo da Igreja Metodista na criação de organismos ecumênicos brasileiros, o ecumenismo sempre enfrentou barreiras internas, mais ou menos explícitas. E o jornal Expositor Cristão, criado para ser um veículo de informação e formação doutrinária, nem sempre comunicou com a necessária clareza qual o significado que a Igreja Metodista confere à palavra ecumenismo e como ela o pratica. Em alguns momentos, a coexistência entre ecumenismo e antiecumenismo no interior do campo metodista não foi trazida à luz dos debates pelo jornal, mas permaneceu oculta por omissões e ambivalências. É o que este trabalho pôde constatar a partir de uma avaliação qualitativa do conteúdo do jornal.(AU)

Introducción

Sexualidad y Escritura (1850-2000) is a collection of thirteen essays which focus on the complex relationship between gender and writing in Spain from 1850 to 2000. This collection aims to provide a specifically Spanish cultural and historical context to the study of gender and writing and to challenge the effectiveness and validity of applying and adapting some feminist theory (based mainly in French and Anglo literary traditions) to works by both male and female Spanish writers. The introduction sets the tone of the essays it contains by discussing the Gilbert and Guar’s concept of female authors anxiety of authorship, and the reasons why their notions of the male dominated writing profession does not necessarily apply to Spanish literature of the nineteenth century in particular. The notable presence and success of female writers during the Romantic period and the way in which they in effect managed to feminize the writing profession illustrates how very different the Spanish literary context is from French, English or American models. The editors state that, rather than needing to work up the courage to take up the pen and publish their works, the issue facing Spanish women writers during parts of the last 150 years has been how to either maintain or regain their authorial voice and their place in letters, fighting to keep their heads above the rising and falling tides of literary trends.

Rethinking comparative and cross national human resource management research

This article first briefly highlights the rapid development of the human resource management (HRM) discipline and the need for more cross-national HRM studies. The universal applicability of Anglo-Saxon models of HRM is then questioned. To examine the applicability of HRM models in different settings (national and international), five main HRM models are critically analysed and their main research propositions are identified. This provides the basis for a framework for HRM evaluations in different contexts. Based on such a framework and developments in the literature, finally, a contextual model is proposed for conducting cross-national and comparative HRM studies. The paper also indicates some related directions for future research.

Organizational commitment profiles and job satisfaction among Greek private and public sector employees

Recent research into organizational commitment has advocated a profiles-based approach. However, with the exception of Wasti, published findings are confined to North American samples. This article examines the relationships between organizational commitment profiles and job satisfaction in Greece. Greek organizations have rarely been the subject of detailed examination, so the study provides baseline information regarding levels of organizational commitment and job satisfaction in Greece. Both private sector (N = 1119) and public sector (N = 476) employees in Greece were surveyed, as this sectoral distinction is regularly associated with different patterns of job-related attitudes. The contrasts between Greek and Anglo-American values present a new challenge to the profiles approach. The results confirm the utility of the profiles approach to the study of organizational commitment. Affective organizational commitment was found to be most influential with respect to levels of intrinsic and extrinsic job satisfaction. This concurs with other studies of the behavioural outcomes of commitment. Copyright © 2007 Sage Publications.

Ethnic diversity as a multilevel construct:the combined effects of dissimilarity, group diversity, and societal status on learning performance in work groups

The authors present a model of the multilevel effects of diversity on individual learning performance in work groups. For ethnically diverse work groups, the model predicts that group diversity elicits either positive or negative effects on individual learning performance, depending on whether a focal individual’s ethnic dissimilarity from other group members is high or low. By further considering the societal status of an individual’s ethnic origin within society (Anglo versus non-Anglo for our U.K. context), the authors hypothesize that the model’s predictions hold more strongly for non-Anglo group members than for Anglo group members. We test this model with data from 412 individuals working on a 24-week business simulation in 87 four- to seven-person groups with varying degrees of ethnic diversity. Two of the three hypotheses derived from the model received full support and one hypothesis received partial support. Implications for theory development, methods, and practice in applied group diversity research are discussed.

Management role in employee participation:a comparative study of multi-national enterprises in India and the U.K.

This research is an Anglo-Indian comparative case study. It studies managerial action in the participation arena of two British multi-nationals i.e. Cadbury Limited and ICI plc. The research was carried out in matched pairs of factories of the above named companies, located in the Midlands of the UK and in Bombay in India. The data for this research was collected through semi-structured interviews with managers and non-management actors, study of company documents and non-participant observation of some participation forums. The research conceptualises the idea of a `participation arena' consisting of the structures, processes, purposes and dynamics of participation. This arena is visualised as broadly reflecting the organisation structure and can be divided into corporate, unit and shopfloor level. Managerial action in this arena is examined in terms of interaction between three sets of factors i.e. company business objectives, strategies and policies; managerial values of power and control; and the responses of unions. Similarities and differences between management action in the home and host plants of the two multi-national companies are also examined. The major findings of the research are as follows. There is significant difference between the participation arena of the parent and the subsidiary company. The latter is marked by absence of higher level participation forums and lack of opportunity for employees to discuss, let alone influence, key decisions. This results from parent company control over key activities of the subsidiary. The similarities in management action in the participation arenas of the two companies in both countries can be attributed to the operation of the three sets of factors mentioned above. Nevertheless, the particular circumstances of each company are a greater influence on managerial action than the national context. Finally, future areas of research in this field are explored.

Understanding accountants' participation in accounting information systems implementation : Malaysian evidence

The study is a two-part study starting with a nationwide survey in the private sector. The hypotheses derived from the Western literature were not significantly supported when the results were analyzed. It seems that the existing literature related to the phenomenon under investigation is mainly Anglo-Saxon culture oriented which is different from the Malaysian culture where the study was conducted. However, access barriers to private sector organizations shifted the focus of the research to the second part of the study that examined the issues in detail in four public sector organizations currently implementing accounting information systems – two hospitals and two universities. In the second part of the main study, the researcher developed formal and substantive propositions from the qualitative interviews which were substantiated using a cross-case analysis; as a result, a model for accountants’ participation in AIS implementation is proposed. The research shows that the process of influencing accountants to participate in AIS implementation is more complex than the literature suggests. There were many issues that surfaced during the case studies, such as conflict and empowerment which set a foundation for further research about how participation can be secured to help make the implementation of AIS part of an organizational agenda success.
