Restoration of forests in low- and middle-income countries (LMICs) has the potential to contribute to international carbon mitigation targets. However, high upfront costs and variable cashflows are obstacles for many landholders. Carbon payments have been promoted as a mechanism to incentivize restoration and economists have suggested cost-sharing by third parties to reduce financial burdens of restoration. Yet empirical evidence to support this theory, based on robust, dynamic field sampling is lacking. Here we use large, long-term datasets from Panama to evaluate the financial prospects of three forest restoration methods under different cost-sharing and carbon payment designs where income is generated through timber harvests. We show some, but not all options are economically viable. Further work combining growth and survival data from field trials with more sophisticated financial analyses is essential to understanding barriers and realizing the potential of forest restoration in LMICs to help meet global carbon mitigation commitments. Forest restoration in LMICs can contribute to global C mitigation targets. Here, the authors assess the economic feasibility of forest restoration methods in Panama, i.e. natural regeneration, native species plantings, and enrichment planting, showing that not all methods are economically viable.

IntroductionDiabetic foot ulceration (DFU) is a common and challenging complication of diabetes. Risk stratification can guide further management. We aim to evaluate the prognostic performance of bedside tests used for peripheral arterial disease (PAD) diagnosis to predict DFU healing.Research design and methodsTesting for Arterial Disease in Diabetes (TrEAD) was a prospective observational study comparing the diagnostic performance of commonly used tests for PAD diagnosis. We performed a secondary analysis assessing whether these could predict DFU healing. Follow-up was performed prospectively for 12 months. The primary outcome was sensitivity for predicting ulcer healing. Secondary endpoints were specificity, predictive values, and likelihood ratios for ulcer healing.Results123 of TrEAD participants with DFU were included. In 12 months, 52.8% of ulcers healed. The best negative diagnostic likelihood ratio (NDLR) was observed for the podiatry ankle duplex scan (PAD-scan) monophasic or biphasic with adverse features(NDLR 0.35, 95% CI 0.14–0.90). The highest positive likelihood ratios were observed for toe brachial pressure index of ≤0.2 (positive diagnostic likelihood ratio (PDLR) 7.67, 95% CI 0.91–64.84) and transcutaneous pressure of oxygen of ≤20 mm Hg (PDLR 2.68, 95% CI 0.54–13.25). Cox proportional hazards modeling demonstrated significantly greater probabilities of healing with triphasic waveforms (HR=2.54, 95% CI 1.23–5.3, p=0.012) and biphasic waveforms with non-adverse features (HR=13.67, 95% CI 4.78–39.1, p<0.001) on PAD-scan.ConclusionsNo single test performed well enough to be used in isolation as a prognostic marker for the prediction of DFU healing.Trial registration number NCT04058626.

The studies comprising this volume, most of them appearing for the first time in English, deal with some of the main topics in Maimonides’ philosophy and that of his followers in Provence. At the heart of these topics lies the issue of whether they adopted a completely naturalistic picture of the workings of the world order, or left room for the volitional activity of God in history. These topics include divine law, creation, the Account of the Chariot, prophet and sage, Mosaic prophecy, reasons for the commandments, and prayer. Special attention is paid to three lesser known but highly significant Provençal Jewish thinkers: Moses Ibn Tibbon, Levi ben Avraham, and Nissim ben Moses of Marseille.

There is growing interest among farmers in the northeast US in silvopasture and other practices that would help them expand their agricultural land base in this forested region. Unfortunately, little quantitative data exist regarding forage performance and economic outcomes associated with different forest-to-agriculture conversion strategies, particularly for the northern tier of states. This research examined forage dry matter production and quality in six forage treatments (orchardgrass, bluegrass, brome, and perennial ryegrass bicultures with white clover; cut hay; and a control) in newly-established silvopastures and open pastures converted from an early successional northern hardwood forest in New York. In addition, we conducted a financial analysis of the establishment of both agricultural systems, as well as a thinned forest treatment managed solely for wood products. Total forage dry matter production (planted forages plus volunteer grasses) was greater in open pastures than silvopastures in the first year after establishment; however, no differences in total forage production were found between silvopastures and open pastures in June or August of the second year. Total forage dry matter production was greater in the orchardgrass-white clover biculture compared to the control treatment in both years. Orchardgrass percent crude protein was lower in open pastures (10.7%) compared to silvopastures (12.9%) in June of year two. The financial analysis indicated that silvopasture outperformed open pasture and thinned forest treatments in terms of both IRR and NPV. We conclude that forage production in silvopastures can be competitive with that in open pastures on sites with a similar, forested, starting condition.

We report a case of spontaneous necrotizing myositis of the biceps brachii in an immunocompetent patient with no comorbidities. We highlight the diagnostic challenges with this case, the utility of computed tomography in diagnosing soft tissue infections, and the importance of source control in septic patients.

Examines Maimonides' political thought in light of his medieval Aristotelian and Jewish sources.

Finding suitable tree species that not only grow well on nutrient poor soils but are also safe financial investments is one of the major obstacles to successful reforestation efforts in the tropics. Our study compared the financial viability and growth of valuable timber species in monocultures and mixtures on infertile soils. Our work shows the extraordinary growth in volume and value of Dalbergia retusa and Terminalia amazonia while underscoring the poor financial viability of Tectona grandis and Pachira quinata, all commonly planted timber species in Panama and much of Central and South America. Using Bayesian statistics, our predictions show that T. amazonia monocultures could reach nearly 200 m3 ha−1 of merchantable volume after 30 years compared to the ~ 40 m3 ha−1 that T. grandis could accumulate in the same time frame. While D. retusa monocultures did not have the highest predicted merchantable volumes of all the species, it did have the highest predicted net present value (NPV), with a predicted mean NPV of > US$97,000 ha−1, quadrupling the species with the next highest monoculture’s NPV, T. amazonia monocultures (~ US$20,000 ha−1). Our work emphasizes that reforestation can be financially viable on low nutrient soils, even in the absence of fertilization or other silvicultural manipulations, if species selection and site are carefully considered and matched.

There has been increasing interest in research on creating word lists in the past decade with more than 60 separate lists being published along with Nation’s (2016) timely Making and Using Word Lists for Language Learning and Testing. However, this focus on word lists has primarily been on creating them and has not necessarily extended to looking at how they are actually used. In order to help answer the question of how these lists are utilized in practice, this exploratory, interpretive study based on interviews with teachers and assessment/curriculum developers looks at how word lists are used at five tertiary English foundation programs in the United Arab Emirates.The main findings include the following. Insufficient vocabulary knowledge was deemed one of the most significant problems that students faced. Additionally, word lists played a role in all five of the institutions represented in the study, and the Common European Framework (CEFR) was used in conjunction with vocabulary frequency lists to help set expected vocabulary learning in some programs. Furthermore, teacher intuition was used to modify lists in three of the five programs and online applications were used in all five programs.The thesis explores a number of areas in depth including: how vocabulary lists are being used in the programs, the use of the AWL in this context and potential problems related to this, the role of teacher intuition in the customization of lists, the role of CEFR related frameworks in these programs, the use of computer applications to assist with list vocabulary acquisition, what the selected vocabulary acquisition activities tell us about beliefs about vocabulary teaching and learning, and some final comments about utilizing a list.One of the key findings was the development of a novel framework for categorizing the use of word lists into four general areas: course planning, teaching and learning, assessment and materials development with sub-categories for each. This framework and the related examples could be utilized to evaluate the suitability of specific lists and to help set developmental targets for the process of adopting a new list and transforming it into something that could be used to direct and support vocabulary teaching and learning. It could also be developed further as more examples of practice emerge in different contexts and hopefully set the stage for more development about how vocabulary lists are used.

Modern and historical Japanese societies are and were quite comfortable with a nature defined, designed, and dominated by humans. While contemporary Japanese are concerned about the environment, especially about non-timber (\"green\") forest resources, conservation organizations are generally small and locally focused. Public forests, accounting for 40 percent of all Japan's forests, are intensively managed. At the national level, the timber program is operating below cost and there is increasing emphasis on non-timber management and rural economic development. A professional elite largely determines forest management goals and cultural barriers minimize broad public participation. Increasingly aware of the environmental impacts of their industrial society at home and abroad, the Japanese are becoming more environmentally concerned. Government agencies are especially proactive in enhancing environmental understanding among Japanese citizens and in sharing their resource management expertise with other Pacific Rim nations.
