National Approach

In England and Wales the placing of effluent discharge consents within a statistical framework has led to the development of a new hybrid type of river quality model. Such catchment scale consent models have a stochastic component for the generation of model inputs and a deterministic component to route them through the river system. This paper reviews and compares the existing approaches for consent modelling used by various Water Authorities. A number of possible future developments are suggested including the potential need for a national approach to the review and setting of long term consents.

Mean Variance

This paper proposes modified mean-variance risk measures for long-term investment portfolios. Two types of portfolios are considered: constant proportion portfolios and increasing amount portfolios. They are widely used in finance for investing assets and developing derivative securities. We compare the long-term behavior of a conventional mean-variance risk measure and a modified one of the two types of portfolios, and we discuss the benefits of the modified measure. Subsequently, an optimal long-term investment strategy is derived. We show that the modified risk measure reflects the investor’s risk aversion on the optimal long-term investment strategy; however, the conventional one does not. Several factor models are discussed as concrete examples: the Black–Scholes model, Kim–Omberg model, Heston model, and 3/2 stochastic volatility model.

Cryptocurrencies are a modern kind of financial instrument (Hudson & Urquhart, 2019), the first cryptocurrency is Bitcoin , proposed by who called Satoushi Nakamato (2008), as The open source was created on the proof-of-concept principle that transactions can be securely treated on a decentralized peer to peer network without the need for a central clearinghouse, which appeared 2009 ( Heid, 2013). The success of the bitcoin blazes a trail to what called ‘Altcoin” this expression means all the cryptocurrencies that set in motion after the victory of the bitcoin, these coins sell themselves as the best alternatives for the bitcoin (FRANKENFIELD, 2020) . There are many types for the altcoin. The third type of the cryptocurrency is called Tokens Unlike Bitcoin and Altcoins, tokens are not able to activate independently and are dependent on the grid of another cryptocurrency. That means they do not have their own core DLT or blockchain, but instead, are built on top of an existing cryptocurrency’s blockchain (Types of cryptocurrencies: explaining the major types of cryptos, 2019). The worth of bitcoin doesn’t depend on any tangible asset or economies of the countries while it is based upon the security of an algorithm which traces all transactions (Hudson & Urquhart, 2019). The studies determine the number of the bitcoin price development in the long -run (Ciaian, Rajcaniova, & Kancs, 2018): • Market forces of the Bitcoin supply and demand • The bitcoin’s attractiveness for the investors • The influence of global macro-financial developments If you're forming an investment strategy designed to help you trail long-term financial intentions, understanding the relationship between company size, return potential, and risk is vital. (Market cap—or market capitalization—refers to the total value of all a company's shares of stock, 2017) .Hence , Manifested importance a cryptocurrency’s market capitalization as the total values of all coins currently in circulation. the cryptocurrency’s market cap contains what’s called Bitcoin Dominance that is the ratio between the market cap of bitcoin to other coins of the cryptocurrency markets (jacobcanfield, 2019) . Cryptocurrency trade is attractive type of investment. this market treated the same of the foreign exchange and stock market ( Radityo, Munajat, & Budi, 2017).

In nineteenth century Britain atmospheric pollution from coal-fired industrialization was on the order of 50 times higher than today. We examine the effects of these emissions on child development by analysing the heights on enlistment during WWI of men born in England and Wales in the 1890s. We find a strong negative relationship between adult heights and the coal intensity of the districts in which these men were observed as children in the 1901 census. The subsequent decline in atmospheric pollution likely contributed to the long-term improvement in health and increase in height.

This paper takes a large-scale social perspective in describing a national project in Australia that was premised on local school communities working together and contributing ideas for the benefit of their students, and potentially, the whole country. The project was intended to improve schools’ capacity for educating boys, and in the long-term, the learning outcomes of under-performing boys, using evidence-based and action research methods. It was supported by the web spaces and tools of the National Quality Schooling Framework and Think.com. This paper emphasises the structures and processes teachers engaged in while building knowledge through their daily work, where the resulting ideas became the property of the whole community. Analyses focus on the extent to which an underlying social structure for knowledge building developed in various parts of the nation during the project, making it possible to characterize a process for innovations in education with commitment to continual idea improvement. Résumé Le présent article adopte une perspective sociale à grande échelle pour décrire un projet national en Australie fondé sur la collaboration des communautés scolaires locales et leur contribution d’idées au bénéfice de leurs élèves et, éventuellement, de l’ensemble du pays. Le projet avait pour but de rendre les écoles plus aptes à éduquer les garçons et, à long terme, d’améliorer les résultats d’apprentissage des garçons qui sous-performent à l’aide de méthodes de recherche-action fondées sur des données probantes. Il a bénéficié du soutien des espaces et des outils Web du National Quality Schooling Framework et de Think.com. Le présent article met l’accent sur les structures et les processus que les enseignants ont utilisés dans leur travail quotidien pour la coélaboration de connaissances; les idées qui en ont résulté sont par la suite devenues la propriété de l’ensemble de la communauté. Les analyses portent principalement sur la mesure dans laquelle une structure sociale sous-jacente de coélaboration des connaissances s’est développée en différents endroits de la nation au cours du projet, ce qui rend possible la caractérisation d’un processus d’innovation en éducation avec un engagement envers l’amélioration continue.

The World

The paper considers two main original approaches to investing the assets of institutional investors (the total amount of their assets in the world is about 100 trillion dollars) – the one of Norway's sovereign wealth fund Global and approach of Yale's endowment fund. Fund Global with assets of $ 716 billion dollars is the largest institutional investor in the world, its strategy is based on the assumption that markets are efficient and their long-term growth lies in the balance of investment in stocks , bonds, and , since more recent time - in real estate. Financiers of Yale in the 1990s revolutionized the approach to investment, firstly, by reducing the proportion of stocks and bonds in favor of private equity and real estate, and secondly , by shift from investments in the domestic market to foreign markets. Not all institutional investors are ready to follow these strategies because of the risk of negative returns in times of crises, but in the medium- and long-term, these approaches allow to beat inflation. For example, Yale's endowment has grown since 1985 to 2012 from 1.6 to 19 billion dollars, and high yield allows to transmit 1 billion dollars (!) to the budget of the university annually. Endowment funds are one of the key sources of revenues of leading American universities. Analysis of the investment policy of endowment funds and sovereign wealth funds shows that fundamental changes in the concept of investing began to occur since the late 1980s - early 1990s . Institutional investors of both these types ceased to focus on conservative instruments - bonds and deposits , and use other options: Global - stocks , Yale – private equity , hedge funds, real estate investments , etc. With the expand of the spectrum of instruments in which the funds are invested the income volatility increases either, and therefore the institutional investors should be both transparent and explain to the public the motives of investment strategy changes.

It was originally proposed that this paper should be entitled ‘Property Investment’, but it was found to be quite impossible to condense such a subject satisfactorily. Also, a paper was presented to the Society some eight years ago entitled ‘An Introduction to Property Investment’, by Lane and Leach (J.S.S. 5, 166). It is thought that the two papers can be read together with advantage. What has been done in this paper is to provide a series of statements and opinions with a view to provoking thought and discussion. Many points may be raised which have been left out. Much, no doubt, has been put in which is obvious and elementary.We are concerned with Property Investment on a long-term basis, i.e. we are not concerned with speculation, namely, the quick purchase and re-sale of property to make a profit; furthermore, we are not concerned with House Purchase schemes. It must also be emphasized that this paper relates to England and Wales and not to Scotland. In the authors' view, basically sound property investment as distinct from owner occupation is very difficult indeed to achieve in Scotland, owing to rating complications, low yields, horizontal ownerships and other legal difficulties.

The Cost

Purpose. Five years of bisphosphonate treatment have proven efficacy in reducing fractures. Concerns exist that long-term bisphosphonate treatment may actually result in an increased number of fractures. This study evaluates, in the context of England and Wales, whether it is cost-effective to conduct a randomized controlled trial (RCT) and what sample size may be optimal to estimate the efficacy of bisphosphonates in fracture prevention beyond 5 years. Method. An osteoporosis model was constructed to evaluate the cost-effectiveness of extending bisphosphonate treatment from 5 years to 10 years. Two scenarios were run. The 1st uses long-term efficacy data from published literature, and the 2nd uses distributions elicited from clinical experts. Results of a proposed RCT were simulated. The expected value of sample information technique was applied to calculate the expected net benefit of sampling from conducting such an RCT at varying levels of participants per arm and to compare this with proposed trial costs. Results. Without further information, the better duration of bisphosphonate treatment was estimated to be 5 years using the published data but 10 years using the elicited expert opinions, although in both cases uncertainty was substantial. The net benefit of sampling was consistently high when between 2000 and 5000 participants per arm were recruited. Conclusions. An RCT to evaluate the long-term efficacy of bisphosphonates in fracture prevention appears to be cost-effective for informing decision making in England and Wales.

Long Term Experiments

SUMMARYYield (or other variate) values from crops recurring on the same plots in long-term experiments are subject to correlations known as serial plot correlations. Neglect of these plot correlations can result in loss of efficiency in the estimation of treatment effects and bias in the estimation of error.Serial plot correlations are calculated from 12 experiments on arable crops in England and Wales, for yields 4, 6 or 8 years apart. They are usually positive, with average value 0·2. In one set of experiments the losses in efficiency caused by plot correlations of this magnitude are shown to be small, but some of the biases in the estimates of error are large. Biases in the variances of treatment means can be wholly or partly eliminated by separating two components of error, plot error and plot x year error.
