  4. Thesis ; Online: Functional interrelations of governance elements and their effects on tropical deforestation - combining qualitative and quantitative approaches

    Fischer, Richard

    2020  

    Abstract: The global rate of annual net forest loss has slowed from 7.8 mio hectares in the 1990s to 4.7 mio hectares between 2015 and 2020. Nevertheless, the area of the world’s forests continues to decrease specifically in the tropics. Improved governance has ... ...

    Abstract The global rate of annual net forest loss has slowed from 7.8 mio hectares in the 1990s to 4.7 mio hectares between 2015 and 2020. Nevertheless, the area of the world’s forests continues to decrease specifically in the tropics. Improved governance has come into the focus as a means to help reversing trends of tropical deforestation. Yet, “good governance”remains a normative, broad and often unspecified concept consisting of a wide range of elements and implicit value judgements. Specific knowledge is missing on the relative importance of single governance elements, on their interdependencies and their specific effects on deforestation. Forest governance research to date has a strong focus on qualitative approaches. This study aims to (i) elaborate on and implement mixed methods for forest governance measurements, (ii) determine functional relationships between forest governance elements based on quantitative data, and to (iii) substantiate and quantify governance effects on tropical deforestation. The presented research develops a new method called quantitative content analysis with standardized scores. The method is applied in a literature review comprising 28 reviewed publications. This review classifies governance elements based on the framework of the World Resource Institute. It quantifies effects on deforestation for single elements by Likert scores. In addition, this study presents a harmonized landscape level governance assessment methodology which is developed and implemented in research areas covering approximately 500,000 hectares in Ecuador, Zambia and the Philippines. Both methods combine qualitative and quantitative approaches and are shown to be applicable and operational. In order to analyze functional relationships between governance elements, principal component analysis (PCA) is applied to all data sets. The results show two general main mechanisms. Firstly, there is a joint positive loading of governance elements on the first principal component for all data sets. Governance elements thus ...

  5. Article: Trading independence for impact? Empirical evidence for increased impact of direct policy engagement is still missing

    Abstract Recent publications are critical about the impact that forest governance research has on halting tropical deforestation. They suggest more engagement of scientists with decision-makers in order to increase research impact. But current theories of science communication point out that engagement with decision-makers and independence of researchers occur at the expense of each other, which is an impediment to analytical science. In our commentary we compile how the authors of recent publications deal with this dilemma and pose the question if possibly enhanced impact can justify or necessitate more engagement. We show that the assumption whereas more impact can be generated through more direct engagement is mostly based on essays, comments, or reviews and hardly on empirical findings. In a Special Focus we therefore use the existing data set of (Karcher et al., 2021) for a first quantitative empirical evaluation on the subject and show that more direct engagement is not necessarily related to more impact. We conclude that more specific empirical research is needed that comparatively assesses researchers' independence for different modes of engagement. This needs to consider different policy contexts and levels as well as stages of research projects and should rely on standardized measures to evaluate their success. For the moment, we provide a number of recommendations that can help to navigate the dilemma between engagement and independence. They include awareness raising within the scientific community, clear and transparent specification of the different roles that researchers can play, links with independent scientific reviewers, diversification of funding sources, and consideration of power and interests of policy-makers which can be study objects and research partners at the same time.

  7. Article ; Online: Preterm prelabor rupture of membranes prior to 33 0/7 weeks: when should rescue corticosteroids be given?

    Abstract Objective: To determine an optimal timing strategy for rescue corticosteroids in gravidas with preterm prelabor rupture of membranes (PPROM) prior to 33 0/7 weeks.
    Methods: This was a retrospective cohort analysis of 109 gravidas with a singleton gestation and PPROM between 23 0/7 and 32 6/7 weeks who delivered at a single inner city tertiary care center. The time of the actual first dose of corticosteroids was chosen as Time 0. The date and time of labor onset, chorioamnionitis, heavy bleeding, cord prolapse, or fetal heart rate decelerations warranting delivery were recorded, as well as the date and time of delivery. We then compared hypothetical timing strategies for administration of the rescue course of corticosteroids at either 1, 2, or 3 weeks after the first course if still undelivered, compared to a strategy of withholding the rescue course until the recognition of spontaneous labor or the need for delivery. For each strategy, we calculated the percentage of gravidas who would have delivered within the optimal window after rescue course corticosteroids, defined as delivery at 24 h to 7 days from the first rescue dose.
    Results: The median time from PPROM to delivery among the 109 gravidas was 8.9 days (interquartile range 4.4-17.9 days). Forty-eight (44%) gravidas delivered within the first week after initial corticosteroid administration, leaving 61 (56%) eligible for a rescue dose. In our hypothetical models, the strategy of giving rescue corticosteroids at either 1, 2, or 3 weeks from the first course would have resulted in 34.4%, 23.0%, and 19.7% of infants being born at 24 h to 7 days after the first rescue dose, respectively. These differences among the three groups or between any two groups were not statistically significant. However, all fixed interval strategies were statistically superior to the strategy of waiting for spontaneous labor or the need for delivery, in which only 4.9% would have delivered within the optimal window.
    Conclusion: In gravidas with PPROM prior to 33 0/7 weeks, giving rescue corticosteroids at a fixed interval of either 1, 2, or 3 weeks after the first course would result in a greater percentage of infants being born within the optimal 24 h to 7 day window compared to administering the rescue course at the onset of labor, infection, bleeding, or abnormal fetal heart rate tracing.
