Heroic viticulture: Environmental and socioeconomic challenges of unique heritage landscapes
Steep-slope agricultural landscapes cover a small fraction of global agricultural areas.1 Despite the limited coverage, they are relevant for high-quality food and wine production, history, and landscape value. On steep slopes, centuries of effort and tradition have created a unique cultural heritage to be preserved. Here, peculiar traditional local knowledge of soil and water conservation combined with agronomic practices (e.g., dry-stone wall terracing) has been handed down for generations. However, such landscapes are fragile and under threat
Inbeslagneming als het zwarte gat van een strafrechtelijk onderzoek en het gemis van een effectieve beklagprocedure
Een van de bekendste bijzondere procedures die in de marge van het reguliere strafproces kunnen worden gevoerd, is de beklagprocedure van artikel 552a Sv. Aan de hand van deze procedure kan een beslagene opkomen tegen het beslag dat op zijn of haar vermogensbestanddelen of eigendommen is gelegd. De praktijk van de inbeslagneming is wijdverbreid: in lopende onderzoeken wordt vaak en ruimhartig, maar ook ongericht en onzorgvuldig beslag gelegd op alles wat wordt aangetroffen en wat bijvoorbeeld later mogelijk verhaal biedt. Een rechterlijke toets van het beslag zou de hoognodige bescherming kunnen bieden aan de beslagene, maar de praktijk wijst uit dat dat in de raadkamer slechts marginaal wordt getoetst. In deze bijdrage wordt ingegaan op de aard en de bijzonderheden van deze beklagprocedure, zowel in de regelgeving als in de strafrechtpraktijk. Het wettelijk kader voor inbeslagneming en het toetsingskader van de beklagrechter worden geschetst, waarna op basis van recente jurisprudentie wordt uiteengezet wat de huidige toetsing van de beklagrechter inhoudt. Uit deze bijdrage volgt dat bij deze toetsing door de rechter een aantal kritische kanttekeningen is te plaatsen. De vraag dringt zich op of voor de beslagene voldoende rechtsbescherming wordt geboden tegen disproportionele inbreuken op diens eigendomsrecht en op de beschikkingsmacht over die eigendommen. Enkele voor de hand liggende praktische alternatieven om beter aan de belangen van de beslagene tegemoet te komen, ontbreken.Criminal Justice: Legitimacy, accountability, and effectivit
Measuring respect and autonomy in Dutch maternity care:Applicability of two measures
Problem: In the Netherlands there are no valid measurement tools available to measure respectful maternity care and women's autonomy. Background: Respectful maternity care including women's autonomy during childbirth are key components of high quality care. Aim: This study aims to evaluate the applicability of the Canadian measures; the Mothers Autonomy in Decision Making (MADM) scale and the Mothers on Respect index (MORi) measures among pregnant women in the Netherlands. Methods: We translated the measures MORi and MADM according to the WHO guidelines, adapted them to the Dutch health care system, evaluated their psychometric properties, and pilot tested before administration through an online cross-sectional survey. We assessed feasibility by calculating descriptive statistics on scores, and reliability by calculating Cronbach's alpha. The construct validity was measured by hypotheses on differences between subgroups based on maternal characteristics, pregnancy characteristics and healthcare provision. Findings: Of 557 women included in the study, 83% experienced high respect and 62% experienced high autonomy. Both the MORi and MADM showed feasibility, internal consistency, and with respect to construct validity, both measures discriminated between type of care provision. Compared to women with pregnancy complications, those with a healthy pregnancy reported statistically higher MORi-scores. No differences were observed on MADM-scores. Discussion: Both instruments can be used as quality of care measures aiming to improve care and thus experiences of women. Conclusion: The results of this study support the feasibility, reliability, and to a certain extent known group validity of the Dutch MORi and MADM measures in pregnant women
Coupled wake boundary layer model of wind-farms
We present and test the coupled wake boundary layer (CWBL) model that
describes the distribution of the power output in a wind-farm. The model
couples the traditional, industry-standard wake model approach with a
"top-down" model for the overall wind-farm boundary layer structure. This wake
model captures the effect of turbine positioning, while the "top-down" portion
of the model adds the interactions between the wind-turbine wakes and the
atmospheric boundary layer. Each portion of the model requires specification of
a parameter that is not known a-priori. For the wake model, the wake expansion
coefficient is required, while the "top-down" model requires an effective
spanwise turbine spacing within which the model's momentum balance is relevant.
The wake expansion coefficient is obtained by matching the predicted mean
velocity at the turbine from both approaches, while the effective spanwise
turbine spacing depends on turbine positioning and thus can be determined from
the wake model. Coupling of the constitutive components of the CWBL model is
achieved by iterating these parameters until convergence is reached. We
illustrate the performance of the model by applying it to both developing
wind-farms including entrance effects and to fully developed (deep-array)
conditions. Comparisons of the CWBL model predictions with results from a suite
of large eddy simulations (LES) shows that the model closely represents the
results obtained in these high-fidelity numerical simulations. A comparison
with measured power degradation at the Horns Rev and Nysted wind-farms shows
that the model can also be successfully applied to real wind-farms.Comment: 25 pages, 21 figures, submitted to Journal of Renewable and

Oil elite networks in a transforming global oil market
This article analyses oil elite formation in light of the wider transformation that is taking place in the global oil order due to the rise of powers from the Global South, including Russia: in particular, the expansion and integration of the state-owned oil companies into the global oil market. This is done by analysing the networks that the directors of the world's largest oil companies create through their affiliations with a) other corporations, b) policy planning bodies and c) with the state. The most important finding is that the increased cooperation between the Western private oil companies and the non-Western state-owned oil companies has not yet translated into increased integration between their respective elite networks. It is argued that this indicates we are witnessing a transition towards a more multi-polar global oil order that increasingly needs to take into account the rising powers of the Global South. © The Author(s) 2012

The impact of dairy products in the development of type 2 diabetes: where does the evidence stand in 2019?
The prevalence of type 2 diabetes (T2D) has increased rapidly. Adopting a heathy diet is suggested as one of the effective behaviors to prevent or delay onset of T2D. Dairy consumption has been recommended as part of a healthy diet, but there remains uncertainty in both the scientific community and the public about the effect of different dairy products on T2D risk. In a recent workshop, the evidence on dairy products and T2D risk was presented and discussed by a group of experts. The main conclusions from the workshop are presented in this position paper and are as follows. 1) Available evidence from large prospective cohort studies and limited randomized controlled trials (RCTs) suggests that total dairy consumption has a neutral or moderately beneficial effect on T2D risk. 2) Increasing evidence from prospective cohort studies indicates that yogurt is most strongly associated with a lower T2D risk, but evidence from RCTs is scarce. 3) Fatty acids from dairy (medium-chain, odd, and very long-chain SFAs as well as trans-palmitoleic acid) are associated with lower T2D risk and improved metabolic health, but more research is needed on studies that explore cause and effect relations to exclude the possibility that the dairy fatty acids simply serve as markers of overall dairy consumption. 4) The food matrix can be a stronger determinant of health effects than SFA content. This review further identifies research gaps in the existing knowledge and highlights key research questions that need to be addressed to better understand the impact of dairy consumption on future T2D risk

IGF1 and insulin receptor single nucleotide variants associated with response in HER2-negative breast cancer patients treated with neoadjuvant chemotherapy with or without a fasting mimicking diet (BOOG 2013-04 DIRECT trial)
Simple Summary: Insulin and insulin-like growth factor 1 (IGF1) are metabolic hormones, which are often upregulated to stimulate proliferation in breast cancer. A fasting mimicking diet (FMD) targets insulin signaling pathway downregulation to hamper tumor growth. Genes encoding for the insulin receptors on the cell's surface contain genetic variation between patients, which can affect insulin receptor function and cellular response. Therefore, a group of 113 patients with HER2-negative breast cancer receiving neoadjuvant chemotherapy with or without a fasting mimicking diet were investigated. We found that two IGF1 receptor variants were associated with worse pathological response compared to the reference alleles, out of the 17 interrogated common variants. Additionally, two IGF1 receptor variants could interact negatively within the FMD group regarding radiological response. These results emphasize that genetic variation harbors predictive clinical relevance to optimize and personalize cancer therapy. Aim: We aimed to investigate associations between IGF1R and INSR single nucleotide variants (SNVs) and clinical response in patients with breast cancer treated with neoadjuvant chemotherapy with or without a fasting mimicking diet (FMD) from the DIRECT trial (NCT02126449), since insulin-like growth factor 1 (IGF1) and the insulin pathway are heavily involved in tumor growth and progression. Methods: Germline DNA from 113 patients was tested for 17 systematically selected candidate SNVs in IGF1R and INSR with pathological and radiological response. Results: IGF1R variants A > G (rs3743259) and G > A (rs3743258) are associated with worse pathological response compared to reference alleles p = 0.002, OR = 0.42 (95%CI: 0.24; 0.73); p = 0.0016; OR = 0.40 (95%CI: 0.23; 0.70). INSR T > C (rs1051690) may be associated with worse radiological response p = 0.02, OR = 2.92 (95%CI: 1.16; 7.36), although not significant after Bonferroni correction. Exploratory interaction analysis suggests that IGF1R SNVs rs2684787 and rs2654980 interact negatively with the FMD group regarding radiological response p = 0.036, OR = 5.13 (95%CI: 1.12; 23.63); p = 0.024, OR = 5.71 (95%CI: 1.26; 25.85). Conclusions: The IGF1R variants rs3743259 and rs3743258 are negatively associated with pathological response in this cohort, suggesting potential relevance as a predictive biomarker. Further research is needed to validate these findings and elucidate the underlying mechanisms and interaction with FMD.Metabolic health: pathophysiological trajectories and therap
Flow and wakes in large wind farms in complex terrain and offshore
Power losses due to wind turbine wakes are of the order of 10 and 20% of total power output in large wind farms. The focus
of this research carried out within the EC funded UPWIND project is wind speed and turbulence modelling for large wind
farms/wind turbines in complex terrain and offshore in order to optimise wind farm layouts to reduce wake losses and loads
