    Regulating private pension funds’ structure, performance and investments: cross-country evidence

    A number of countries have introduced individual, privately managed defined-contribution accounts, where the value of the pension benefit will depend on accumulated contributions and investment returns. These schemes expose workers’ future pension benefits to a number of different risks. To try to mitigate these risks, reforming governments have often strictly regulated the pension fund management industry’s structure, performance, and asset allocation. Structural regulations often force workers to choose only one manager and one fund. So, workers are unable to diversify investments across funds, exposing them to aberrant behaviour by fund managers, and preventing portfolio adjustments according to the individual’s age, household characteristics, career profile and attitude to risk. Strict asset-allocation rules and relative performance criteria mean that pension funds often invest and perform almost identically, removing any substantive choice for workers over the allocation of their pension fund’s assets and the portfolio’s risk and returns. Concentration in the pension fund management industry is found to be higher in the new pension systems of Latin America and Eastern Europe than in most OECD countries. Concentration might be because the new pension markets are smaller than in countries with more established funded pension systems, but it could also be because of restrictions on industry structure. In Latin America, asset allocation and performance is nearly identical across pension funds. So-called ‘herding’ behaviour is almost a defining characteristics of these pension regimes. Again, this reflects, at least in part, asset allocation restrictions and strict performance regulation. There is also evidence that pension funds have often under-performed simple portfolios composed of market indices of stocks and bonds. All the rules imposed in the new systems of Latin American and Eastern Europe seem to be more stringent than in the OECD, with one exception: portfolio limits. Some OECD countries have a tighter investment regime than countries such as Argentina, Chile, Colombia, Peru and Poland. But OECD countries tend to have fewer barriers to entry and impose fewer constraints on performance than Latin American and Eastern European countries

    Regulating private pension funds'structure, performance, and investments : cross-country evidence

    Because defined-contribution systems expose pensions to a number of risks, reforming governments have often strictly regulated the pension fund industry's structure, performance, and investments. This paper compares the rules in the new systems of Latin America and Eastern Europe with richer OECD countries. The authors argue that the benefits of competing pension funds and individual choice can only be achieved if regulations are loosened in the medium term.Pensions&Retirement Systems,Non Bank Financial Institutions,Insurance&Risk Mitigation,Banks&Banking Reform,Environmental Economics&Policies

    This work reports the synthesis, characterization of new (2E)-1-(biphenyl-4-yl)-3-aryl)-prop-2-en-1-one derivatives (C1-C10). The chalcone derivatives were evaluated for in vitro antibacterial, antifungal, antioxidant activities. The compounds exhibited moderate to good antimicrobial activity at MIC 10-40 Όg/mL. The compounds were docked at the active site of the methionyl-tRNA synthetase (metRS) (PDB ID: 1A8H) to predict their putative interactions. The compounds further screened for antioxidant property, amid C5, C7 and C8 exhibited good DPPH radical scavenging activity. Compound C5 was selected for antistress studies against gamma radiation induced oxidative stress markers in E .coli K 12. The C5 pretreatment and irradiated bacteria sample showed modulatory action of stress enzymes SOD and CAT to near basal level and significant demulating effect on the level of TBARS.Keywords: Biphenyl chalcone derivatives, radioprotection, antioxidant activity, antimicrobial activity, molecular dockin

    Large expert-curated database for benchmarking document similarity detection in biomedical literature search

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

    BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

    No full text
    Remote sensing has come a long way in the last three decades. The technology has reached all spheres of human activity and affected our life in innumerable ways. Some of the recent studies in this area have contributed towards better resolution, better precision and opened up a host of new application areas. The era of hyperspectral imaging is on, and it.is expected that it will soon overtake the multispectral imaging within a few years, Synthetic aperture radar interferometery has taken strides towards providing accurate digital elevation models than ever before, the recent shuttle radar topography mission has proven its capability, with a near coverage of the whole globe and the dictum of digital earth is soon going to be a reality. Information extraction from remote sensing .images has reached new heights with recent methodologies like the neural networks and contextual classification, enabling to create and incorporate external knowledge into the classification process. Some of these emerging technologies and processing methods in the context of strategic application areas have been discussed
