Talking in a language that everyone can understand? Clarity of speeches by the ECB executive board
We use data on speeches held by members of the European Central Bank's (ECB) Executive Board to analyze whether clarity of central bank communication has increased over time. Employing readability measures as proxy variables, we find that clarity of information provision is trending upward since the inception of the ECB. The increase is gradual, rather than being induced by changes in the board composition or major macroeconomic events. Clarity is higher for speeches aimed at general audiences and for speeches by female speakers. We also show that media sentiment about the ECB is negatively related to complexity
Carboxylate ion pairing with alkali-metal ions for β-Lactoglobulin and its role on aggregation and interfacial adsorption
We
report a combined experimental and computational study of the
whey protein β-lactoglobulin (BLG) in different electrolyte
solutions. Vibrational sum-frequency generation (SFG) and ellipsometry
were used to investigate the molecular structure of BLG modified air–water
interfaces as a function of LiCl, NaCl, and KCl concentrations. Molecular
dynamics (MD) simulations and thermodynamic integration provided details
of the ion pairing of protein surface residues with alkali-metal cations.
Our results at pH 6.2 indicate that BLG at the air–water interface
forms mono- and bilayers preferably at low and high ionic strength,
respectively. Results from SFG spectroscopy and ellipsometry are consistent
with intimate ion pairing of alkali-metal cations with aspartate and
glutamate carboxylates, which is shown to be more effective for smaller
cations (Li<sup>+</sup> and Na<sup>+</sup>). MD simulations show not
only carboxylate–alkali-metal ion pairs but also ion multiplets
with the alkali-metal ion in a bridging position between two or more
carboxylates. Consequently, alkali-metal cations can bridge carboxylates
not only within a monomer but also between monomers, thus providing
an important dimerization mechanism between hydrophilic surface patches

Talking in a language that everyone can understand? Transparency of speeches by the ECB Executive Board
Using novel data on speeches held by members of the European Central Bank's Executive Board, we investigate whether monetary policy transparency has increased over time. With respect to the general public as the target audience, our findings suggest that the European Central Bank successfully improved the frequency and clarity of information provision since its inception. The increase in transparency is gradual, rather than being induced by changes in the Executive Board's composition or major economic events such as the Great Recession. However, the clarity of speeches in recent years is still fairly low. Moreover, our findings indicate that clarity decreased under Christine Lagarde's presidency following the outbreak of the Coronavirus pandemic. We conclude that while the European Central Bank was able to increase transparency over time, further improvements in clarity are required to make monetary policy truly accessible to the broad public

Estimating Pass-Through Rates for the 2022 Tax Reduction on Fuel Prices in Germany
We analyze the effectiveness of the German tax reduction on fuel prices ('Tankrabatt') that was introduced for three months, starting on 1 June 2022. Using the synthetic control method to compare actual prices of gasoline and diesel to those in a counterfactual situation without the tax reduction, we find that the tax reduction has been completely passed on to consumers for most of the three months. In early June, it took approximately two weeks for the full pass-through to take effect. Moreover, pass-through rates started to decline in August while the tax reduction was still in place. We observe an upward price jump smaller than the size of the expiring tax reduction at the start of September. Our results are robust to different approaches of constructing the synthetic control group
A Survey of Data Mining and Deep Learning in Bioinformatics
The fields of medicine science and health informatics have made great progress recently and have led to in-depth analytics that is demanded by generation, collection and accumulation of massive data. Meanwhile, we are entering a new period where novel technologies are starting to analyze and explore knowledge from tremendous amount of data, bringing limitless potential for information growth. One fact that cannot be ignored is that the techniques of machine learning and deep learning applications play a more significant role in the success of bioinformatics exploration from biological data point of view, and a linkage is emphasized and established to bridge these two data analytics techniques and bioinformatics in both industry and academia. This survey concentrates on the review of recent researches using data mining and deep learning approaches for analyzing the specific domain knowledge of bioinformatics. The authors give a brief but pithy summarization of numerous data mining algorithms used for preprocessing, classification and clustering as well as various optimized neural network architectures in deep learning methods, and their advantages and disadvantages in the practical applications are also discussed and compared in terms of their industrial usage. It is believed that in this review paper, valuable insights are provided for those who are dedicated to start using data analytics methods in bioinformatics
Effects of chemotherapy and hormonal therapy for early breast cancer on recurrence and 15-year survival: an overview of the randomised trials
Background Quinquennial overviews (1985-2000) of the randomised trials in early breast cancer have assessed the 5-year and 10-year effects of various systemic adjuvant therapies on breast cancer recurrence and survival. Here, we report the 10-year and 15-year effects. Methods Collaborative meta-analyses were undertaken of 194 unconfounded randomised trials of adjuvant chemotherapy or hormonal therapy that began by 1995. Many trials involved CMF (cyclophosphamide, methotrexate, fluorouracil), anthracycline-based combinations such as FAC (fluorouracil, doxombicin, cyclophosphamide) or FEC (fluorouracil, epirubicin, cyclophosphamide), tamoxifen, or ovarian suppression: none involved taxanes, trastuzumab, raloxifene, or modem aromatase inhibitors. Findings Allocation to about 6 months of anthracycline-based polychemotherapy (eg, with FAC or FEC) reduces the annual breast cancer death rate by about 38% (SE 5) for women younger than 50 years of age when diagnosed and by about 20% (SE 4) for those of age 50-69 years when diagnosed, largely irrespective of the use of tamoxifen and of oestrogen receptor (ER) status, nodal status, or other tumour characteristics. Such regimens are significantly (2p=0 . 0001 for recurrence, 2p<0 . 00001 for breast cancer mortality) more effective than CMF chemotherapy. Few women of age 70 years or older entered these chemotherapy trials. For ER-positive disease only, allocation to about 5 years of adjuvant tamoxifen reduces the annual breast cancer death rate by 31% (SE 3), largely irrespective of the use of chemotherapy and of age (<50, 50-69, &GE; 70 years), progesterone receptor status, or other tumour characteristics. 5 years is significantly (2p<0 . 00001 for recurrence, 2p=0 . 01 for breast cancer mortality) more effective than just 1-2 years of tamoxifen. For ER-positive tumours, the annual breast cancer mortality rates are similar during years 0-4 and 5-14, as are the proportional reductions in them by 5 years of tamoxifen, so the cumulative reduction in mortality is more than twice as big at 15 years as at 5 years after diagnosis. These results combine six meta-analyses: anthracycline-based versus no chemotherapy (8000 women); CMF-based versus no chemotherapy (14 000); anthracycline-based versus CMF-based chemotherapy (14 000); about 5 years of tamoxifen versus none (15 000); about 1-2 years of tamoxifen versus none (33 000); and about 5 years versus 1-2 years of tamoxifen (18 000). Finally, allocation to ovarian ablation or suppression (8000 women) also significantly reduces breast cancer mortality, but appears to do so only in the absence of other systemic treatments. For middle-aged women with ER-positive disease (the commonest type of breast cancer), the breast cancer mortality rate throughout the next 15 years would be approximately halved by 6 months of anthracycline-based chemotherapy (with a combination such as FAC or FEC) followed by 5 years of adjuvant tamoxifen. For, if mortality reductions of 38% (age <50 years) and 20% (age 50-69 years) from such chemotherapy were followed by a further reduction of 31% from tamoxifen in the risks that remain, the final mortality reductions would be 57% and 45%, respectively (and, the trial results could well have been somewhat stronger if there had been full compliance with the allocated treatments). Overall survival would be comparably improved, since these treatments have relatively small effects on mortality from the aggregate of all other causes. Interpretation Some of the widely practicable adjuvant drug treatments that were being tested in the 1980s, which substantially reduced 5-year recurrence rates (but had somewhat less effect on 5-year mortality rates), also substantially reduce 15-year mortality rates. Further improvements in long-term survival could well be available from newer drugs, or better use of older drugs
