Tree Demography Plots

The pantropical network of large tree demography plots coordinated by the Smithsonian’s Center for Tropical Forest Science has now gone global, as part of the Smithsonian Institution Global Earth Observatories. Some four million tropical trees, representing about 10,000 species, are now tagged, provisionally identified and periodically recensused. Some 3,000 species are captured in the six plots within Malesia. These include species rarely collected and many that are now endangered. Easy location of trees for periodic examination for fertile material and detailed ecological data, together with seasoned in-country research teams, provide unique opportunities for research collaboration

An Evaluation of Health Service Impacts Consequent to Switching from Brand to Generic Venlafaxine in New Zealand under Conditions of Price Neutrality

AbstractObjectiveTo study the health impact on adult New Zealand patients who switch from originator brand to generic venlafaxine.MethodsThe national pharmacy database was used to select patients using venlafaxine for at least 6 months. Switchers and nonswitchers were identified, and switch behavior was compared for a 12-month follow-up period. Change in health service use following switching was also compared between switchers and nonswitchers including use of the emergency department, hospital, and specialist outpatient services over the same period.ResultsApproximately 12% of all originator brand users switched to generic venlafaxine, at least half of whom continued to use the generic throughout the follow-up period to August 1, 2012. Almost 60% of new users of the generic venlafaxine, however, switched to using the originator brand. Aside from a slight reduction in the use of outpatient services among switchers, there were no significant differences in health services use between switchers and nonswitchers for either existing or new venlafaxine users.ConclusionsAlthough both products remain fully subsidized and available, there is little incentive for prescribers, pharmacists, or patients to switch to the less expensive generic brand. If savings to the national New Zealand budget are to be realized, additional policy measures should be implemented to minimize incentives for multiple and reverse switching, and prescribers, as key opinion leaders, could take the lead in promoting generics to their patients

Microwave-assisted synthesis and electrochemical evaluation of VO2 (B) nanostructures

Understanding how intercalation materials change during electrochemical operation is paramount to optimizing their behaviour and function and in situ characterization methods allow us to observe these changes without sample destruction. Here we first report the improved intercalation properties of bronze phase vanadium dioxide VO2 (B) prepared by a microwave-assisted route which exhibits a larger electrochemical capacity (232 mAh g-1) compared with VO2 (B) prepared by a solvothermal route (197 mAh g-1). These electrochemical differences have also been followed using in situ X-ray absorption spectroscopy allowing us to follow oxidation state changes as they occur during battery operation

Public and patient involvement in research on ageing and dementia

Purpose: This paper aims to assess the current state, and various methods, of public and patient involvement, particularly but not exclusively in research on ageing and dementia. Design/methodology/approach: Interviews were carried out with a researcher, who has had a leading role in research on dementia; a public contributor with extensive relevant experience; and a member of the research design service with responsibility for patient and public involvement. Findings: All those involved in the research can benefit considerably from public and patient involvement and it can make a significant difference to the course of a project. The importance of choosing an appropriate method of involvement is discussed and planning for it in both financial terms and time allowed. Examples are given of successful studies. Research limitations/implications: Those who took part in the interviews were chosen for their record in furthering public and patient involvement in research. There is no attempt to compare their views with those of the wider research community. Practical implications: The various ways in which patients and the public are involved in relevant research is a guide to those designing projects and those who may want to explore opportunities for involvement. Social implications: Social implications include being able to influence research projects, contributors of all ages find they are valued. Originality/value: The format of the paper is original, eliciting material from three viewpoints on research and involvement

Characterizing the variation of propagation constants in multicore fibre

We demonstrate a numerical technique that can evaluate the core-to-core variations in propagation constant in multicore fibre. Using a Markov Chain Monte Carlo process, we replicate the interference patterns of light that has coupled between the cores during propagation. We describe the algorithm and verify its operation by successfully reconstructing target propagation constants in a fictional fibre. Then we carry out a reconstruction of the propagation constants in a real fibre containing 37 single-mode cores. We find that the range of fractional propagation constant variation across the cores is approximately $\pm2 \times 10^{-5}$.Comment: 17 pages; preprint format; 5 figures. Submitted to Optics Expres

Is Discussing Identity More Important Than Shared Identity To Student-Staff Relationship Building?

Research consistently demonstrates that the quality of student-staff interactions matters for positive student outcomes. Some research studies also suggest that identity similarities (homophily) often contribute to meaningful human connections. Yet, the influence of student and staff identities on teaching and learning in higher education is less explored. We report on how undergraduate students and staff at one US university perceive the impact of identities on student-staff classroom relationships. Four themes emerged from our analysis: (1) Shared interests may be more important than shared identity for some students and staff; (2) Students’ year of study influences their views on staff identity and student-staff relationships; (3) Identity homophily is a point of connection for some students and staff; (4) Discussing identity, without identity homophily, can lead to positive course-based connections. The first three of these themes align with existing literature, but the fourth theme extends previous research, and we focus on exploring how for some students, discussing identities may be more important than matching identities when interacting with academic staff.
