Introduction of Parasites of the Larch Sawfly in Minnesota

Olesicampe benefactor Hinz and the Bavarian strain of Mesoleius tenthredinis Morley, European ichneunionid parasites of the larch sawfly, Pristiphora erichsonii (Hartig), were introduced into northern Minnesota from Manitoba in 1971 and 1972. Both species are now established. There was also natural spread of 0. benefactor into Minnesota from Manitoba releases in 1961 at a point ca. 200 miles northwest of the Minnesota plots

Providing free maternal health care: ten lessons from an evaluation of the national delivery exemption policy in Ghana

Background: There is a growing movement, globally and in the Africa region, to reduce financial barriers to health care generally, but with particular emphasis on high priority services and vulnerable groups. Objective: This article reports on the experience of implementing a national policy to exempt women from paying for delivery care in public, mission and private health facilities in Ghana. Design: Using data from a complex evaluation which was carried out in 2005-2006, lessons are drawn which can inform other countries starting or planning to implement similar service-based exemption policies. Results: On the positive side, the experience of Ghana suggests that delivery exemptions can be effective and cost-effective, and that despite being universal in application, they can benefit the poor. However, certain ‘negative’ lessons are also drawn from the Ghana case study, particularly on the need for adequate funding, and for strong institutional ownership. It is also important to monitor the financial transfers which reach households, to ensure that providers are passing on benefits in full, while being adequately reimbursed themselves for their loss of revenue. Careful consideration should also be given to staff motivation and the role of different providers, as well as quality of care constraints, when designing the exemptions policy. All of this should be supported by a proactive approach to monitoring and evaluation. Conclusion: The recent movement towards making delivery care free to all women is a bold and timely action which is supported by evidence from within and beyond Ghana. However, the potential for this to translate into reduced mortality for mothers and babies fundamentally depends on the effectiveness of its implementation

Paying for Performance to Improve the Delivery and Uptake of Family Planning in Low and Middle Income Countries: A Systematic Review

Paying for performance is a strategy to meet the unmet need for family planning in low and middle income countries; however, rigorous evidence on effectiveness is lacking. Scientific databases and grey literature were searched from 1994 to May 2016. Thirteen studies were included. Payments were linked to units of targeted services, usually modified by quality indicators. Ancillary components and payment indicators differed between studies. Results were mixed for family planning outcome measures. Paying for performance was associated with improved modern family planning use in one study, and increased user and coverage rates in two more. Paying for performance with conditional cash transfers increased family planning use in another. One study found increased use in the upper wealth group only. However, eight studies reported no impact on modern family planning use or prevalence. Secondary outcomes of equity, financial risk protection, satisfaction, quality, and service organization were mixed. Available evidence is inconclusive and limited by the scarcity of studies and by variation in intervention, study design, and outcome measures. Further studies are warranted

Regions and resources

The goal of this thesis is to bring together several topics for the purpose of site prediction and significance assessment in management archaeology. This was approached as a survey project along a great transect with three sample areas at Boorowa, Cobar and Tibooburra. The field operation was concerned with the methodology of sampling by transect and quadrat, land systems analysis, sample unit coverage and site recording. A technological system for classifying, recording and analysing stone artefacts was developed in order to compare the artefact assemblages within and among the sample areas. The results of the survey showed that the main determinants of artefact morphology were the material type, logistics of access and transport, and the reduction strategy. Few assemblages provided indications of functional differences. Sites with a substantial portion of microblade manufacture were found to be distinctive in terms of the rest of the stone assemblage and site structure. These also were mostly in fine­ grained mosaic environments, and were interpreted as "microblade base camps", with differences in land use strategies from other sites which are presumed to be later in time. Broader patterns of regional variation show a "core tool oriented" pattern east of the Bogan River, and a "flake tool oriented" pattern to the west. Other details concerning hearths, grinding stones and specialised flake tool manufacturing processes were found to vary along the great transect. Methods for measuring this regional variation are proposed in the form of Stone Technological Regions, Land Systems Divisions, Cultural Adaptive Areas and Archaeological Formations. The thesis project and its results are presented as a methodological and theoretical model for developing a research framework in management archaeology

Lipid-protein and protein-protein interactions in the mechanisms of photosynthetic reaction centre and the Na+,K+-ATPase

Lipid-protein and protein-protein interactions are likely to play important roles in the function and regulation of charge-transporting membrane proteins. This thesis focuses on two different membrane proteins, the photosynthetic reaction centre (RC) from purple bacteria and the Na+,K+-ATPase. The influence of the lipid surroundings and cholesterol derivatives on the kinetics of electron transfer of the RC were investigated by reconstituting the protein in phosphatidylcholine vesicles containing cholesterol and derivatives known to modulate the membrane dipole potential. The experiments performed on the Na+,K+-ATPase were designed to contribute to a better understanding of the role that oligomeric protein-protein interactions have in the enzyme’s mechanism. Our results show that the cholesterol derivatives significantly modify the electron transfer kinetics within the RCs and their multiphasic behavior. These effects seem to be associated with the extent of the dipole potential change experienced by the RC within the phospholipid membrane. Indeed, the largest effects on the rates are observed when 6-ketocholestanol and cholesterol are present, consistent by with their previously demonstrated significant increase of the dipole potential. We interpret this data as indicating an increased free energy barrier for protons to enter the protein. The consequences of the increased dipole potential seem to be experienced across the entire protein, since the rates of the P+QA- charge recombination in the presence of AQ- acting as QA are also modified by the same effectors. Also interesting is the effect of the dipole potential on the two conformational states of the RCs (previously reported) as revealed by the biphasic decays of the electron transfer kinetics. In particular, we report for the first time a biphasicity of the P+QA- charge recombination in the WT RCs. This non exponential behaviour, absent in the phospholipid membrane or isolated RCs, is induced by the presence of the cholesterol derivatives, suggesting that the equilibration time between the two RC conformations is slowed down significantly by these molecules. According to this work, the dipole potential seems to be an important parameter that has to be taken into account for a fine understanding of the charge transfer function of the RCs. Reported literature values of the dissociation constant, Kd, of ATP with the E1 conformation of the Na+,K+-ATPase based on equilibrium titrations and kinetic methods disagree. Using isothermal titration calorimetry (ITC) and simulations of the expected equilibrium behaviour for different binding models, this thesis presents an explanation for this apparent discrepancy based on protein-protein interactions. Because of the importance of Mg2+ in ATP hydrolysis, kinetic studies of Mg2+ binding to the protein were also carried out. These studies showed that ATP alone is responsible for Mg2+ complexation, with no significant contribution from the enzyme environment

Simulated tsunami inundation for a range of Cascadia megathrust earthquake scenarios at Bandon, Oregon, USA

Characterizations of tsunami hazards along the Cascadia subduction zone hinge on uncertainties in megathrust rupture models used for simulating tsunami inundation. To explore these uncertainties, we constructed 15 megathrust earthquake scenarios using rupture models that supply the initial conditions for tsunami simulations at Bandon, Oregon. Tsunami inundation varies with the amount and distribution of fault slip assigned to rupture models, including models where slip is partitioned to a splay fault in the accretionary wedge and models that vary the updip limit of slip on a buried fault. Constraints on fault slip come from onshore and offshore paleoseismological evidence. We rank each rupture model using a logic tree that evaluates a model\u27s consistency with geological and geophysical data. The scenarios provide inputs to a hydrodynamic model, SELFE, used to simulate tsunami generation, propagation, and inundation on unstructured grids with \u3c 5-15 m resolution in coastal areas. Tsunami simulations delineate the likelihood that Cascadia tsunamis will exceed mapped inundation lines. Maximum wave elevations at the shoreline varied from similar to 4 m to 25 m for earthquakes with 9-44 m slip and M-w 8.7-9.2. Simulated tsunami inundation agrees with sparse deposits left by the A. D. 1700 and older tsunamis. Tsunami simulations for large (22-30 m slip) and medium (14-19 m slip) splay fault scenarios encompass 80%-95% of all inundation scenarios and provide reasonable guidelines for landuse planning and coastal development. The maximum tsunami inundation simulated for the greatest splay fault scenario (3644 m slip) can help to guide development of local tsunami evacuation zones

New constraints on coseismic slip during southern Cascadia subduction zone earthquakes over the past 4600 years implied by tsunami deposits and marine turbidites

This correction stands to correct Figure 7c listing a low minimum slip of 12 m for Case 2 instead of the correct value of 8 m, as stated in the body of the text and depicted on the chart of cumulative slip. The corrected chart explanation and caption are shown below. This error did not affect any of the findings of the paper or the chart itself. This is a correction to the original article
