\u3cem\u3eOphiostoma clavigerum\u3c/em\u3e is the Mycangial Fungus of the Jeffrey Pine Beetle, \u3cem\u3eDendroctonus jeffreyi\u3c/em\u3e

Dendroctonus jeffreyi and D. ponderosae are sibling species of bark beetles (Coleoptera: Scolyti- dae) with few morphological and molecular genetic differences. The two species are believed to have di- verged relatively recently. Dendroctonus jeffreyi colo- nizes only Pinus jeffreyi, while D. ponderosae colonizes up to thirteen Pinus spp., but not P. jeffreyi. Adult beetles of both D. jeffreyi and D. ponderosae carry sym- biotic fungi in mycangia located on the maxillary car- dines. Dendroctonus ponderosae was known to carry two fungi, Ophiostoma clavigerum and 0. montium, in its mycangia. However, it was not known which fungi might be carried by D. jeffreyi. Fungi were isolated from the mycangia of over 900 D. jeffreyi collected from a large portion of its geographic range. Using morphology, isozyme phenotypes, and growth rates at different temperatures, all isolates from D. jeffreyi mycangia were determined to be 0. clavigerum; 0. montium was never isolated from D. jeffreyi mycangi

\u3cem\u3eLeptographium pyrinum\u3c/em\u3e is a Mycangial Fungus of \u3cem\u3eDendroctonus adjunctus\u3c/em\u3e

Several species of Dendroctonus (Coleop- tera: Scolytidae) have cuticular invaginations, or my- cangia, in the integument which are specialized for carrying specific symbiotic fungi. The mycangium of Dendroctonus adjunctus, located under a callus that surrounds the prothorax, has been recognized but the mycangial fungus has not yet been identified. Fungi from mycangia of Dendroctonus adjunctus were isolated and compared with Leptographium pyrinum and Ophiostoma adjuncti, two species of fungi known to be present in trees colonized by Dendroctonus ad- junctus. Fungi isolated from Dendroctonus adjunctus mycangia were determined to be morphologically and genetically identical to Leptographium pyrinu

Genetic Relationships Among \u3cem\u3eLeptographium terebrantis\u3c/em\u3e and the Mycangial Fungi of Three Western \u3cem\u3eDendroctonus\u3c/em\u3e Bark Beetles

Morphology, mitochondrial DNA (mtDNA) restriction fragment polymorphisms (RFLPs) and nuclear DNA (nDNA) fingerprinting were used to clarify relationships among the morphologically similar Ophiostoma and Leptographium species associated with mycangia of three Dendroctonus bark beetles (Ophiostoma clavigerum associated with both D. ponderosae and D. jeffreyi, and L. pyrinum associated with D. adjunctus), as well as a closely related nonmycangial bark beetle associate (L. terebrantis). Most isolates of O. clavigerum form long (40-70 μm), septate conidia, while all isolates of L. terebrantis and L. pyrinum form conidia less than 17.0 μm in length. The conidia of L. pyrinum are pyriform, with truncate bases, while the conidia of the other species form only slightly truncate bases. Conidial masses of L. terebrantis are creamy yellow, while the conidial masses of the other species are white. Nuclear DNA fingerprints resulting from probing PstI restrictions with the oligonucleotide probe (CAC)(5) and HaeIII and MspI restrictions of mtDNA, exhibited three major clusters. In the dendrogram developed from mtDNA RFLPs, the L. pyrinum isolates formed one cluster, while the majority of O. clavigerum isolates, including all D. jeffreyi isolates, formed another. A third cluster was composed of all L. terebrantis isolates, as well as several O. clavigerum isolates from D. ponderosae. The inclusion of some O. clavigerum isolates in the L. terebrantis cluster suggests that horizontal transfer of mtDNA has occurred among these fungi. The nDNA dendrogram also exhibited three clusters, and most isolates of L. pyrinum, L. terebrantis and O. clavigerum grouped separately; however, one isolate of O. clavigerum grouped with the L. terebrantis isolates, while one isolate of L. terebrantis grouped with O. clavigerum. No genetic markers were found that distinguished between O. clavigerum associated with D. ponderosae and O. clavigerum associated with D. jeffreyi. Ophiostoma clavigerum might be a recently diverged morphological variant of L. terebrantis, with special adaptations for grazing by young adults of D. jeffreyi and D. ponderosae. The anamorph of O. clavigerum, Graphiocladiella clavigerum, is transferred to Leptographium

The comparative evaluation of ERTS-1 imagery for resource inventory in land use planning

The author has identified the following significant results. Multidiscipline team interpretation and mapping of resources for Crook County is nearly complete on 1:250,000 scale enlargements of ERTS-1 imagery. Maps of geology, landforms, soils and vegetation-land use are being interpreted to show limitations, suitabilities and geologic hazards for land use planning. Mapping of lineaments and structures from ERTS-1 imagery has shown a number of features not previously mapped in Oregon. A timber inventory of Ochoco National Forest has been made. Inventory of forest clear-cutting practices has been successfully demonstrated with ERTS-1 color composites. Soil tonal differences in fallow fields shown on ERTS-1 correspond with major soil boundaries in loess-mantled terrain. A digital classification system used for discriminating natural vegetation and geologic materials classes has been successful in separation of most major classes around Newberry Cauldera, Mt. Washington and Big Summit Prairie. Computer routines are available for correction of scanner data variations; and for matching scales and coordinates between digital and photographic imagery. Methods of Diazo film color printing of computer classifications and elevation-slope perspective plots with computer are being developed

The comparative evaluation of ERTS-1 imagery for resource inventory in land use planning

The author has identified the following significant results. Multidiscipline team interpretation and mapping of resources for Crook County is complete on 1:250,000 scale enlargements of ERTS imagery and 1:120,000 hi-flight photography. Maps of geology, soils, vegetation-land use and land resources units were interpreted to show limitations, suitabilities, and geologic hazards for land use planning. Mapping of lineaments and structures from ERTS imagery has shown a number of features not previously mapped in Oregon. A multistage timber inventory of Ochoco National Forest was made, using ERTS images as the first stage. Inventory of forest clear-cutting practices was successfully demonstrated with color composites. Soil tonal differences in fallow fields correspond with major soil boundaries in loess-mantled terrain. A digital classification system used for discriminating natural vegetation and geologic material classes was successful in separating most major classes around Newberry Caldera, Mt. Washington, and Big Summit Prairie

Human rights and public education

This article attempts a contrast to the contribution by Hugh Starkey. Rather than his account of the inexorable rise of human rights discourse, and of the implementation of human rights standards, human rights are here presented as always and necessarily scandalous and highly contested. First, I explain why the UK has lagged so far behind its European neighbours in implementing citizenship education. Second, a comparison with France shows that the latest UK reforms bring us up to 1789. Third, the twentieth-century second-generation social and economic rights are still anathema in the UK. Fourth, the failure to come to terms with Empire and especially the slave trade means that the UK’s attitude to third-generation rights, especially the right of peoples to self-determination, is heavily compromised. Taking into account the points I raise, citizenship education in the UK might look very different

Doing more with less: Teacher professional learning communities in resource-constrained primary schools in rural China.

Teacher professional learning communities provide environments in which teachers engage in regular research and collaboration. They have been found effective as a means for connecting professional learning to the day-to-day realities faced by teachers in the classroom. In this article, the authors draw on survey data collected in primary schools serving 71 villages in rural Gansu Province as well as transcripts from in-depth interviews with 30 teachers. Findings indicate that professional learning communities penetrate to some of China’s most resource-constrained schools but that their nature and development are shaped by institutional supports, principal leadership, and teachers’ own initiative

Ethical and compliance-competence evaluation: a key element of sound corporate governance

Motivated by the ongoing post-Enron refocusing on corporate governance and the shift by the Financial Services Authority (FSA) in the UK to promoting compliance- competence within the financial services sector, this paper demonstrates how template analysis can be used as a tool for evaluating compliance-competence. Focusing on the ethical dimension of compliance-competence, we illustrate how this can be subjectively appraised. We propose that this evaluation technique could be utilised as a starting point in informing senior management of corporate governance issues and be used to monitor and demonstrate key compliance and ethical aspects of an institution to external stakeholders and regulators

Analysis of the profile, characteristics, patient experience and community value of community hospitals : a multimethod study

Background: Community hospitals have been part of England’s health-care landscape since the mid-nineteenth century. Evidence on them has not kept pace with their development. Aim: To provide a comprehensive analysis of the profile, characteristics, patient experience and community value of community hospitals. Design: A multimethod study with three phases. Phase one involved national mapping and the construction of a new database of community hospitals through data set reconciliation and verification. Phase two involved nine case studies, including interviews and focus groups with patients (n = 60), carers (n = 28), staff (n = 132), volunteers (n = 68), community stakeholders (n = 74) and managers and commissioners (n = 9). Phase three involved analysis of Charity Commission data on voluntary support. Setting: Community hospitals in England. Results: The study identified 296 community hospitals with beds in England. Typically, the hospitals were small (<30 beds), in rural communities, led by doctors/general practitioners (GPs) and nurses, without 24/7 on-site medical cover, providing step-down and step-up inpatient care, with an average length of stay of <30 days and a variable range of intermediate care services. Key to patients’ and carers’ experiences of community hospitals was their closeness to ‘home’ through their physical location, environment and atmosphere and the relationships that they support; their provision of personalised, holistic care; and their role in supporting patients through difficult psychological transitions. Communities engage with and support their hospitals through giving time (average = 24 volunteers), raising money (median voluntary income = £15,632), providing services (voluntary and community groups) and giving voice (e.g. communication and consultation). This can contribute to hospital utilisation and sustainability, patient experience, staff morale and volunteer well-being. Engagement varies between and within communities and over time. Community hospitals are important community assets, representing direct and indirect value: instrumental (e.g. health care), economic (e.g. employment), human (e.g. skills development), social (e.g. networks), cultural (e.g. identity and belonging) and symbolic (e.g. vitality and security). Value varies depending on place and time. Limitations: There were limitations to the secondary data available for mapping community hospitals and tracking charitable funds and to our sample of case study respondents, which concentrated on people with a connection to the hospitals. Conclusions: Community hospitals are diverse but are united by a set of common characteristics. Patients and carers experience community hospitals as qualitatively different from other settings. Their accounts highlight the importance of considering the functional, interpersonal, social and psychological dimensions of experience. Community hospitals are highly valued by their local communities, as demonstrated through their active involvement as volunteers and donors. Community hospitals enable the provision of local intermediate care services, delivered through an embedded, relational model of care, which generates deep feelings of reassurance. However, current developments, including the withdrawal of GPs, shifts towards step-down care for non-local patients and changing configurations of services, providers and ownership may undermine this. Future work: Comparative studies of patient experience in different settings, longitudinal studies of community support and value, studies into the implications of changes in community hospital function, GP involvement, provider-mix and ownership and international comparative studies could all be undertaken
