Genetic diversity of root-associated fungal endophytes from Calluna vulgaris at contrasting field sites

A total of 107 putative ericoid mycorrhizal endophytes were isolated from hair roots of Calluna vulgaris from two abandoned arsenic/copper mine sites and a natural heathland site in southwest England. The endophytes were initially grouped as 14 RFLP types, based on the results of ITS-RFLP analysis using the restriction endonucleases Hinf I, Rsa I and Hae III. ITS sequences were obtained for representative isolates from each RFLP type and compared phylogenetically with sequences for known ericoid mycorrhizal endophytes and selected ascomycetes. The majority of endophyte isolates (62-92%) from each site were identified as Hymenoscyphus ericae, but a number of other less common mycorrhizal RFLP types were also identified, all of which appear to have strong affinities with the order Leotiales. None of the less common RFLP types was isolated from C. vulgaris at more than one field site. Neighbour-joining analysis indicated similarities between the endophytes from C. vulgaris and mycorrhizal endophytes isolated from other Ericaceae and Epacridaceae hosts in North America and Australia.

Cross-colonization of scots pine (Pinus sylvestris) seedlings by the ectomycorrhizal fungus Paxillus involutus in the presence of inhibitory levels of Cd and Zn

The effects of Cd and Zn on cross-colonization by Paxillus involutus of Scots pine seedlings was examined by using pairs of ectomycorrhizal (ECM) and non-mycorrhizal (NM) seedlings grown in the same vessel. This was done to assess, first, the ability of P. involutus to colonize NM Scots pine seedlings by growth from colonized roots of other Scots pine seedlings in the presence of Cd or Zn, and, second whether ECM colonization of Scots pine by P. involutus provided a competitive advantage over NM seedlings. Ectomycorrhizal colonization of Scots pine was shown to be more sensitive than Scots pine itself to Cd and Zn, but prior colonization did provide a competitive advantage with respect to biomass production. This beneficial effect over NM seedlings was, however, equal in the control, Cd and Zn treatments, and was due simply to growth stimulation in the presence of ECM colonization. Cross-colonization from an ECM to a NM seedling was reduced but not prevented by Cd and Zn. Cd had a more negative effect on cross-colonization than on initial colonization of seedlings, whereas Zn had an equally inhibitory effect on both parameters. These results have important implications for plant establishment on metal-contaminated sites. If cross-colonization between plants is reduced by toxic metals, plant establishment on contaminated sites might be retarded.

Toxic interactions of metal ions (Cd2+, Pb2+, Zn2+ and Sb3- on in vitro biomass production of ectomycorrhizal fungi

A number of ectomycorrhizal (ECM) fungi, from sites uncontaminated by toxic metals, were investigated to determine their sensitivity to Cd^2-, Pb²⁺, Zn²⁺ and Sb^3-, measured as an inhibition of fungal biomass production. Isolates were grown in liquid media amended with the metals, individually (over a range of concentrations) and in combination (at single concentrations) to determine any significant interactions between the metals. Significant interspecific variation in sensitivity to Cd²⁺ and Zn²⁺ was recorded, while Pb²⁺ and Sb^3- individually had little effect. The presence of Pb²⁺ and Sb^3- in the media did however, ameliorate Cd²⁺ and Zn²⁺ toxicity in some circumstances. Interactions between Cd²⁺ and Zn²⁺ were investigated further over a range of concentrations. Zn²⁺ was found to significantly ameliorate the toxicity of Cd²⁺ to three of the four isolates tested. The influence of Zn²⁺ varied between ECM species and with the concentrations of metals tested.

Statin use after diagnosis of breast cancer and survival: a population-based cohort study

BACKGROUND: Preclinical studies have shown that statins, particularly simvastatin, can prevent growth in breast cancer cell lines and animal models. We investigated whether statins used after breast cancer diagnosis reduced the risk of breast cancer-specific, or all-cause, mortality in a large cohort of breast cancer patients.

METHODS: A cohort of 17,880 breast cancer patients, newly diagnosed between 1998 and 2009, was identified from English cancer registries (from the National Cancer Data Repository). This cohort was linked to the UK Clinical Practice Research Datalink, providing prescription records, and to the Office of National Statistics mortality data (up to 2013), identifying 3694 deaths, including 1469 deaths attributable to breast cancer. Unadjusted and adjusted hazard ratios (HRs) for breast cancer-specific, and all-cause, mortality in statin users after breast cancer diagnosis were calculated using time-dependent Cox regression models. Sensitivity analyses were conducted using multiple imputation methods, propensity score methods and a case-control approach.

RESULTS: There was some evidence that statin use after a diagnosis of breast cancer had reduced mortality due to breast cancer and all causes (fully adjusted HR = 0.84 [95% confidence interval = 0.68-1.04] and 0.84 [0.72-0.97], respectively). These associations were more marked for simvastatin 0.79 (0.63-1.00) and 0.81 (0.70-0.95), respectively.

CONCLUSIONS: In this large population-based breast cancer cohort, there was some evidence of reduced mortality in statin users after breast cancer diagnosis. However, these associations were weak in magnitude and were attenuated in some sensitivity analyses.

Counselling Psychology in the United Kingdom

Counselling psychology within the UK has grown over the last three decades, adapting to many changes in the field of applied psychology, whilst remaining true to its core values and humanistic origins. The identity of counselling psychology is strongly rooted in a relational stance and applied psychology, where attention to psychological formulation is given to improve psychological functioning and well-being. This article outlines a brief history of counselling psychology in the UK, the training process, credentialing and looks at some important challenges and future directions for counselling psychology in the UK. A proportion of the members from the British Psychological Society’s division of counselling psychology (DCoP, N = 148) took part in the study. Participants provided demographic, training, employment, workplace and career pathway information obtained through an online questionnaire distributed to all DCoP members. On the whole, DCoP members are working in a variety of areas within the UK and the findings of this article contribute to the international study comparing counselling psychology across the globe.

A Global Portrait of Counselling Psychologists’ Characteristics, Perspectives, and Professional Behaviors

Counselling psychologists in eight countries (Australia, Canada, New Zealand, South Africa, South Korea, Taiwan, the United Kingdom, and the United States) responded to survey questions that focused on their demographics as well as their professional identities, roles, settings and activities. As well, they were asked about satisfaction with the specialty and the extent to which they endorsed 10 core counselling psychology values. This article reports those results, focusing both on areas in which there were between-country similarities as well as on those for which there were differences. These data provide is a snapshot of counselling psychology globally and establish a foundation for the other articles in this special issue of the journal.

Prospects and Problems for Religious Education in England, 1967-1970: Curriculum Reform in Political Context

This article provides an historical case study of an abortive attempt to revise policy and legislation relating to Religious Education (RE) in English schools in the late 1960s and early 1970s. Drawing upon published sources, including parliamentary debates, as well as previously unutilised national archival sources from the Department of Education and Science, it comments upon events which have hitherto been omitted from the historiography of RE, but which help to contextualise significant changes in RE theory and practice at that time. Moreover, it demonstrates that the current parlous state of RE in schools is in part the result of latent and longstanding issues and problems, rather than a consequence of present-day government policy alone. Therefore, in reviewing and developing RE policies and practices, all stakeholders are urged to look more closely at both changes and continuities in the subject’s past and the contexts in which they occurred.

The Professionalisation of Non-Denominational Religious Education in England: Politics, Organisation and Knowledge

In response to contemporary concerns, and using neglected primary sources, this article explores the professionalisation of teachers of Religious Education (RI/RE) in non-denominational, state-maintained schools in England. It does so from the launch of Religion in Education (1934) and the Institute for Christian Education at Home and Abroad (1935) to the founding of the Religious Education Council of England and Wales (1973) and the British Journal of Religious Education (1978). Professionalisation is defined as a collective historical process in terms of three inter-related concepts: (1) professional self-organisation and professional politics, (2) professional knowledge, and (3) initial and continuing professional development. The article sketches the history of non-denominational religious education prior to the focus period, to contextualise the emergence of the professionalising processes under scrutiny. Professional self-organisation and professional politics are explored by reconstructing the origins and history of the Institute of Christian Education at Home and Abroad, which became the principal body offering professional development provision for RI/RE teachers for some fifty years. Professional knowledge is discussed in relation to the content of Religion in Education which was oriented around Christian Idealism and interdenominational networking. Changes in journal name in the 1960s and 1970s reflected uncertainties about the orientation of the subject and shifts in understanding over the nature and character of professional knowledge. The article also explores a particular case of resistance, in the late 1960s, to the prevailing consensus surrounding the nature and purpose of RI/RE, and the representativeness and authority of the pre-eminent professional body of the time. In conclusion, the article examines some implications which may be drawn from this history for the prospects and problems of the professionalisation of RE today.

The Consequences of Gender in Homogamic Couples

In studies which analyse the social distance between spouses at the moment a couple is formed, and which attempt to understand the role of the family, and in particular of marriage, in crystallising social divisions, the concept of homogamy has often been purely descriptive. This article questions this static approach and seeks to pinpoint the changes which social homogamy undergoes in the course of conjugal life, addressing women’s decisions on work–family articulation. Drawing on a critical approach to the concept of rational choice, the article intends to demonstrate the merit of an interpretative approach by analysing how members of a sample of 27 university-educated Portuguese partnered mothers take their decisions in the context of an interdependency framework in which the dynamics of family interaction tend to thwart individual career path development, rendering spouses dependent on each other.

O governo da linguagem cerimonial: costume etiqueta no Timor-Leste colonial

Este ensaio explora o elevado significado adquirido por antigos costumes e cerimoniais na gestão de poder, status e autoridade socio-política em Timor-Leste, com especial enfoque no período compreendido entre as décadas de 1850 e 1910. Argumenta-se que, em Timor colonial, a cerimonialidade formava a linguagem e a tecnologia através da qual a autoridade político-jural Portuguesa e Timorense se constituía e se exercia nas interacções coloniais. A cerimonialidade garantia o exercício do comando assim como a comunicação social entre os actores coloniais portugueses e os povos e as classes dirigentes timorenses, numa diversidade de situações: durante interacções pacíficas e conjuntivas, mas também, e de modo importante, em ocasiões de tensão política, conflito, ou violência física iminente.

Women in the driving seat Eastern European immigrant women s citizenship participation and educational inclusion in Portugal

This paper is a case study of Eastern European immigrant women’s social inclusion in Portugal through civic participation. An analysis of interviews conducted with women leaders and members of two ethnic associations provides a unique insight into their migrant pathways as highly educated women and the ways in which these women are constructing their citizenship in new contexts in Northern Portugal. These women’s accounts of their immigrant experience embrace both the public realm, in using their own education and their children’s as a means of integration but also spill over into ‘non-public’ familial relationships at home in contradictory ways. These include the sometimes traditional, gender-defined division of labour within the associations and at home and the new ways that they negotiate their relative autonomies to escape forms of violence and subordination that they face as women and immigrants.

Que faire du couple local/global ? Pour une anthropologie pleinement processuelle

This article examines the uses of the local/global dichotomy in anthropology. It is argued that the use of these terms as analytical tools tends to lead to a reification of "global forces" seen as external to the local site where the ethnographic study takes place. To avoid endless debates on whether or not the "global" can be the object of ethnographic scrutiny, anthropologists should treat the local and the global as scalar properties of social systems that are generated in the course of historical processes.

Biomedical risk assessment as an aid for smoking cessation.

BACKGROUND: A possible strategy for increasing smoking cessation rates could be to provide smokers who have contact with healthcare systems with feedback on the biomedical or potential future effects of smoking, e.g. measurement of exhaled carbon monoxide (CO), lung function, or genetic susceptibility to lung cancer. OBJECTIVES: To determine the efficacy of biomedical risk assessment provided in addition to various levels of counselling, as a contributing aid to smoking cessation. SEARCH STRATEGY: We systematically searched the Cochrane Collaboration Tobacco Addiction Group Specialized Register, Cochrane Central Register of Controlled Trials 2008 Issue 4, MEDLINE (1966 to January 2009), and EMBASE (1980 to January 2009). We combined methodological terms with terms related to smoking cessation counselling and biomedical measurements. SELECTION CRITERIA: Inclusion criteria were: a randomized controlled trial design; subjects participating in smoking cessation interventions; interventions based on a biomedical test to increase motivation to quit; control groups receiving all other components of intervention; an outcome of smoking cessation rate at least six months after the start of the intervention. DATA COLLECTION AND ANALYSIS: Two assessors independently conducted data extraction on each paper, with disagreements resolved by consensus. Results were expressed as a relative risk (RR) for smoking cessation with 95% confidence intervals (CI). Where appropriate a pooled effect was estimated using a Mantel-Haenszel fixed effect method. MAIN RESULTS: We included eleven trials using a variety of biomedical tests. Two pairs of trials had sufficiently similar recruitment, setting and interventions to calculate a pooled effect; there was no evidence that CO measurement in primary care (RR 1.06, 95% CI 0.85 to 1.32) or spirometry in primary care (RR 1.18, 95% CI 0.77 to 1.81) increased cessation rates. We did not pool the other seven trials. One trial in primary care detected a significant benefit of lung age feedback after spirometry (RR 2.12; 95% CI 1.24 to 3.62). One trial that used ultrasonography of carotid and femoral arteries and photographs of plaques detected a benefit (RR 2.77; 95% CI 1.04 to 7.41) but enrolled a population of light smokers. Five trials failed to detect evidence of a significant effect. One of these tested CO feedback alone and CO + genetic susceptibility as two different intervention; none of the three possible comparisons detected significant effects. Three others used a combination of CO and spirometry feedback in different settings, and one tested for a genetic marker. AUTHORS' CONCLUSIONS: There is little evidence about the effects of most types of biomedical tests for risk assessment. Spirometry combined with an interpretation of the results in terms of 'lung age' had a significant effect in a single good quality trial. Mixed quality evidence does not support the hypothesis that other types of biomedical risk assessment increase smoking cessation in comparison to standard treatment. Only two pairs of studies were similar enough in term of recruitment, setting, and intervention to allow meta-analysis.
