...The Role of Public Participation in Organic Waste Management A Case Study of Abuja, Nigeria ABSTRACT Environmental management issues continue to pose greater challenges to various regions across the globe. The municipality of Abuja suffers from low level of public participation in engaging in organic waste management as one of the main ways of achieving environmental sanitation. In a bid to identify ways of enhancing public participation in organic waste management, the study used qualitative primary research, which involved interviewing 57 members of the public through questionnaires. The participants were picked on a simple random basis. From the results the study established that there has been a low level participation amongst the members of the public in organic waste management. The low participation results from some specific obstacles or factors inhibiting the same. Amongst the obstacles identified include lack of adequate funding, insufficient resources, lack of information, ineffective policies and regulation framework, and lack of awareness as some of the obstacles that have inhibited public participation in organic waste management. As a result, the study provides specific recommendations on how to enhance public participation in organic waste management as one of the ways of promoting environmental sanitation.

...Bootstrapping (statistics) From Wikipedia, the free encyclopedia In statistics, bootstrapping is a method for assigning measures of accuracy (defined in terms of bias, variance, confidence intervals, prediction error or some other such measure) to sample estimates.[1][2] This technique allows estimation of the sampling distribution of almost any statistic using only very simple methods.[3][4] Generally, it falls in the broader class of resampling methods. Bootstrapping is the practice of estimating properties of an estimator (such as its variance) by measuring those properties when sampling from an approximating distribution. One standard choice for an approximating distribution is the empirical distribution of the observed data. In the case where a set of observations can be assumed to be from an independent and identically distributed population, this can be implemented by constructing a number of resamples of the observed dataset (and of equal size to the observed dataset), each of which is obtained by random sampling with replacement from the original dataset. It may also be used for constructing hypothesis tests. It is often used as an alternative to inference based on parametric assumptions when those assumptions are in doubt, or where parametric inference is impossible or requires very complicated formulas for the calculation of standard errors.

Общая характеристика валютных операций Под валютными рисками понимается вероятность возникновения убытков от изменения обменных курсов в процессе внешнеэкономической деятельности, инвестиционной деятельности в других странах, а также при получении экспортных кредитов. Валютный, или курсовой риск — это вероятность того, что изменения курсов иностранных валют (доллара, фунтов стерлингов, франка, йены и т. д.) приводят к появлению у банка убытков вследствие изменения рыночной стоимости его активов и пассивов. В 1970-80-х годах наблюдались гораздо более резкие колебания обменных курсов валют и процентных ставок, чем в предыдущие периоды. После краха Бреттон-Вудской валютной системы в начале 1970-х годов, которая была заменена системой плавающих валютных курсов, стали появляться первые попытки управления валютным риском. Амплитуда колебаний валютных курсов в 1980-х годах увеличилась. Другим серьезным ударом по экономике в этот период был рост процентных ставок. Вместе взятые: плавающий валютный курс и изменяющиеся процентные ставки привели экономистов и банкиров к более тщательному анализу по управлению валютного риска. Важно установить наличие валютного риска при сделке и выяснить, как этот риск может быть покрыт. Валютная ставка может изменяться как в пользу продавца, так и в пользу покупателя, и это нельзя игнорировать. ...

...Fuel Hedging in the Airline Industry: The Case of Southwest Airlines Executive Summary From December 21, 1998 to September 11, 2000, jet fuel prices increased 255%, from 28.50 cents/gallon to 101.25 cents/gallon. While jet fuel prices have declined from their highs, at a price of 79.45 cents/gallon, they are still significantly above the December 1998 lows. With the future price of jet fuel being unpredictable, Southwest has decided to implement a trading strategy in an effort to mitigate its exposure to adverse price movements in jet fuel. To do this, Southwest has settled on 5 possible strategies: (1)Do nothing; (2) Hedge using plain vanilla jet fuel or heating oil swap; (3) Hedge using options; (4) Hedge using a zero-cost collar strategy; or (5) Hedge using a crude oil or heating oil futures contract. The merits and demerits of each strategy are discussed in depth below. After evaluating the possible scenarios, it is our recommendation that Southwest implement a hedging strategy that involves a combination of the jet fuel swap and the heating oil swap. The combined strategy will allow Southwest to achieve the lowest net jet fuel costs, while limiting the risks associated with the strategies individually, such as counterparty risk for the jet fuel swap and basis risk for the heating oil swap. Concerning the split between the two strategies, a 50/50 even split is recommended. Why Hedge? Hedging is a financial strategy that enables airlines or other investors...

Email: as@ufrj.br ABSTRACT: This paper examines the performance of bivariate volatility models for the crude oil spot and future returns of the WTI type barrel prices. Besides the volatility of spot and future crude oil barrel returns time series, the hedge ratio strategy is examined through the hedge effectiveness. Thus this study shows hedge strategies built using methodologies applied in the variance modelling of returns of crude oil prices in the spot and future markets, and covariance between these two market returns, which correspond to the inputs of the hedge strategy shown in this work. From the studied models the bivariate GARCH in a Diagonal VECH and BEKK representations was chosen, using three different models for the mean: a bivariate autoregressive, a vector autoregressive and a vector error correction. The methodologies used here take into consideration the denial of assumptions of homoscedasticity and normality for the return distributions making them more realistic.

...Derivatives and Hedging Over recent years, the volatility in the financial markets has increased due to substantial changes domestically and internationally. This has given rise to increased financial price risks faced by both domestic and multi-national companies. Financial Derivatives are widely used by corporations to adjust to exposure to currency risk, interest rate risks, commodity price risks, and security holdings risk. Largely, companies are currently exposed to risks caused by unexpected movements in exchange rates and interest rates. Companies with a growing global presence are especially exposed to a wide range of financial risks, in particular foreign exchange risks and interest rate risk. Although, financial risks are the center of business operations of financial service firms, but they also impact the risk exposure of non-financial corporations. The management and supervision of these risks has become vital for the existence of companies in today’s unpredictable financial markets. The major financial risks that most firms are exposed to are interest rate risk, currency rate risk, commodity price risk, and security holdings risk. Interest rate risk is a very common type of risk, and result from a discrepancy in the sensitivity of a firms assets and liabilities to interest rate movements. On the other hand, currency risk exposure is virtually encountered by all firms, even if their exposure is not from a transaction or a translation risk. Many firms are...

...Currency Hedging When companies conduct business across borders, they must deal in foreign currencies. Companies must exchange foreign currencies for home currencies when dealing with receivables, and vice versa for payables. This is done at the current exchange rate between the two countries. Foreign exchange risk is the risk that the exchange rate will change unfavorably before payment is made or received in the currency . For example, if a United States company doing business in Japan is compensated in yen, that company has risk associated with fluctuations in the value of the yen versus the United States dollar.[1] ------------------------------------------------- Hedge[edit] A hedge is a type of derivative, or a financial instrument, that derives its value from an underlying asset. Hedging is a way for a company to minimize or eliminate foreign exchange risk. Two common hedges are forward contracts and options. A forward contract will lock in an exchange rate today at which the currency transaction will occur at the future date.[2] An option sets an exchange rate at which the company may choose to exchange currencies. If the current exchange rate is more favorable, then the company will not exercise this option.[2] The main difference between the hedge methods is who derives the benefit of a favourable movement in the exchange rate. With a forward contract the other party derives the benefit, while with an option the company retains the benefit by choosing not to exercise...

No part of this paper may be reproduced in any form, or stored in a retrieval system, without prior permission of the author(s). Hedging With Futures Contract: Estimation and Performance Evaluation of Optimal Hedge Ratios in the European Union Emissions Trading Scheme John Hua Fan, Eduardo Roca and Alexandr Akimov Department of Accounting, Finance and Economics, Griffith University, Queensland, Australia 4111 Abstract Following the introduction of the European Union Emissions Trading Scheme, CO2 emissions have become a tradable commodity. As a regulated party, emitters are forced to take into account the additional carbon emissions costs in their production costs structure. Given the high volatility of carbon price, the importance of price risk management becomes unquestioned. This study is the first attempt to calculate hedge ratios and to investigate their hedging effectiveness in the EU-ETS carbon market by applying conventional and recently developed models of estimation. These hedge ratios are then compared with those derived for other markets. In spite of the uniqueness and novelty of the carbon market, the results of the study are consistent with those found in other markets...

Conclusion 6. Data Analysis, Graphics and Tables 7. Bibliography Introduction The hedging of jet fuel by major airlines is the topic of this project. Hedging is considered by some as a form of insurance, similar to the kind you buy for your personal use (health, life, auto) or for your business (fire, flood, cargo). The process of hedging fuel and its derivatives is far more complicated than going out to buy a homeowner’s insurance policy, for example. We will address the different types of hedging strategies that can and are being implemented by some of the major global carriers and we will also take a look at those carriers who do not practice hedging at all. Hedging allows airlines to “insure” themselves against a negative event, such as a sharp rise in fuel prices due to a shortage in oil production. Hedging is simply a way that some airlines use to try and reduce the uncertainty and volatility of jet fuel prices. For example, if a major airline is currently generating a profit, they can try to protect that profit by hedging their fuel needs and...

...The American Institute for Foreign Study (AIFS) is an organization, which helps enable American students to travel abroad. The main service AIFS provides entails organizing educational and cultural exchange problems across the globe. As the case explains, AIFS has split their business into two major divisions that that serve American student’s studying abroad; the Study Abroad College division and the High School Travel division. The college division, which is controlled by Christopher Archer-Lock, sends American students all over the world on semester-long exchange programs. The high school division, which was founded as the American Council for International Studies (ACIS), is controlled by Becky Tabaczynski and sends high school students and their teachers on 1-4 week long trips. This nature of business involves a certain amount of bottom-line risk. AIFS focuses largely on American students studying abroad, therefore the majority of their revenue is in American Dollars (USD). However, AIFS costs’ are generally incurred in foreign currency (primarily Euros (EUR) and British Pounds (GBP)) because the services they arrange for happen abroad. Due to their business activities involving foreign currencies, an unfavorable change in the exchange rate could result in a higher cost base, and potentially a loss overall if the change is significant enough. Inherently, due to the nature of their business, AIFS is exposed to currency risk because they are dealing in multiple currencies...

...housing’s inflation hedge capabilities. Mixed and varied empirical results have been demonstrated in Switzerland (Hamelink and Hosli, 1996), Canada (Newell, 1995), Hong Kong (Ganesan and Chiang, 1998), Singapore (Sing and Low, 2000) and China (Chu and Sing, 2004). Chen and Sing (2006) examined the inflation-hedging ability of five international housing markets (namely Hong Kong, Tokyo, Singapore, Taipei and London). Their results show that the inflation-hedging features of housing vary significantly across different markets. This finding also highlights the importance of international evidence on the inflation-hedging effectiveness of housing. In Malaysia, the inflation-hedging effectiveness of residential property has been largely ignored, although there are some studies in housing portfolio management (Hui, 2010; Lee and Ting, 2011). In addition, no study has been undertaken to compare the inflation-hedging attributes of different types of residential property. Given the unique features of the Malaysian housing market, a dedicated study in this market is critical. Inflation-hedging characteristics 65 4. Data and methodology Data To assess the inflation-hedging features of Malaysian residential property, the quarterly Malaysian housing indices from the Valuation and Property Services Department, Malaysia over 1999:Q1-2012:Q1 were obtained.
