Effect of stem age on the response of stem diameter variations to plant water status in tomato

Plant water status plays a major role in glasshouse cultivation of tomato (Solanum lycopersicum L.). New climate control technologies alter the glasshouse climate and make it less dependent on solar radiation. However, irrigation strategies are still often based on solar radiation sums. In order to maintain a good plant water status, it is interesting to use plant-based methods such as monitoring sap flow (F) or stem diameter variations (SDV). Though SDV give important information about plant water status, an unambiguous interpretation might be difficult because other factors such as stem age, fruit load and sugar content of the stem also affect SDV. In this study, an analysis of the effect of stem age on the response of SDV to water status was performed by calibration of a mechanistic flow and storage model. This allowed us to determine how parameter values changed across the growing season. Tissue extensibility decreased over the growing season resulting in a lower growth rate potential, whereas daily cycles of shrinking and swelling of the stem became more pronounced towards the end of the growing season. Parameters were then adapted to time-dependent variables and implemented in the model, allowing long term simulation and interpretation of SDV. Sensitivity analysis showed that model predictions were very sensitive to initial sucrose content of the phloem tissue and the parameters related to plastic growth

VBTB-proof? Het veiligheidsprogramma nader beschouwd

Al vele jaren en op vele manieren wordt getracht de overheidsprestaties te verbeteren. Binnen de openbare financiën is de transformatie van een input- naar een outputbegroting een van de meest ingrijpende wijzigingen op dit vlak. In de voetsporen van andere OECD-landen startte de Nederlandse regering enkele jaren geleden het project ‘Van Beleidsbegroting tot Beleidsverantwoording’ (VBTB), dat moet leiden tot een toegankelijker en beleidsgerichter begroting en jaarverslag. Vooral ten aanzien van prestatiegegevens liggen de resultaten achter op de ambities. Binnen het beleidsdomein lijkt dit beter te gaan, getuige bijvoorbeeld de opzet van beleidsprogramma’s, die vaak ingekleed zijn met een uitgebreid rapportagestramien voor het volgen van de voortgang van het beleid. In dit artikel wordt de informatiewaarde van deze prestatiegegevens nader verkend. Daartoe wordt geanalyseerd in hoeverre een beleidsprogramma, te weten het Veiligheidsprogramma, VBTB-proof is. De resultaten daarvan bieden tevens handvatten voor een nadere beoordeling van de (on)mogelijkheden van een resultaatgerichte begroting

Performance Informed Budgeting in Europe: The Ends Justify the Means, Don’t They?

The last few decades a revival of the performance budgeting generating a complete performance industry. Initiated by the Anglo-Saxon countries, notably New Zealand, the performance movement is widespread today. In this paper we focus on the efforts of the three European countries - Finland, the Netherlands and Spain - to link inputs to outputs and/or the results by looking at three questions: " What is the rationale for budgetary reform? " What is the orientation of budgetary reform: outputs or results? " Is budgetary reform successful? Fiscal stress is a key driver in all cases, but not the only reason for budgetary reform. Other factors such as the Maastricht criteria for qualification and participation in the EMU have served as a trigger for budgetary reform. The approach differs from country to country, but they are all focused on the performance informed budgeting. Besides, the latest developments point in the direction of a more down to earth attitude to the expectations of budgetary reform. The success of budgetary reform hinges on the quality of performance information that is assumed a necessary but not sufficient condition for the use of performance information. All complain about the quality of performance information. Moreover, they all struggle with the link of the inputs to the outputs or results that makes us conclude, addressing the question that we raised in the subtitle of our paper, that the ends do not justify - neither moral nor empirical - the means as well as resources

Performance Budgeting in the Netherlands: Beyond Arithmetic

Performance-based budgeting seems to be a promising tool for improving the management and accountability of public finances. However, its application causes many difficulties. This article briefly reviews international experience with performance-based budgeting and explores its application in the Netherlands since the late 1990s, including a case study of the Safety Programme. The focus is on transparency and the quality of the performance information. Compared to the former input budget, performance-based budgeting constitutes a major step forward. Given the many difficulties in implementing performance budgeting, it is recommendable, though, to critically revise its scope and shape

The feasibility and efficacy of a multidisciplinary intervention with aftercare meetings for fibromyalgia

The objective of this study is to examine the feasibility and long-term results of a 12-week multidisciplinary part-time daycare intervention with five aftercare meetings in fibromyalgia (FM) patients. One hundred and five patients diagnosed with FM started with a multidisciplinary intervention and were assessed for feasibility, functional status (Fibromyalgia Impact Questionnaire [FIQ]), and quality of life (EuroQol-5D [EQ-5D]) until 9 months after completion. The program consisted of sociotherapy, physiotherapy, psychotherapy, and creative arts therapy. Drop-out rate was 4.8%. The attendance rate of 100 patients who completed the 12-week program and five aftercare meetings was high (97.4%), just like patient and therapist satisfaction (8.2 on a 10 points scale). After the 12-week program, statistically significant improvement was seen in both FIQ and EQ-5D. This improvement was maintained after 9 months of follow-up. On average, moderate improvements were observed. Our 12-week multidisciplinary part-time daycare intervention with five aftercare meetings for FM patients is feasible and it is indicated that it can lead to sustained improvement in functional status and quality of life
