The study was undertaken to investigate how willing would farmers be to pay for agricultural extension service in Nigeria. A multistage random sampling technique was used to select 268 respondents. Results showed that most farmers (95.1 per cent) were willing to pay for improved extension service as long as the service remained relevant to their needs. Farmers were willing to pay N1000 annually as their own share of the service cost. The most important factors that influenced farmers’ willingness to pay were states of origin, items originally paid for, major occupation, minor occupation, number of years in school and sale of farm produce.

We present results from 30 nights of observations of the open cluster NGC 7789 with the Wide Field Camera on the Isaac Newton Telescope, La Palma. From ~900 epochs, we obtained light curves and Sloan r'-i' colours for ~33000 stars, with ~2400 stars having better than 1 per cent precision. We expected to detect ~2 transiting hot Jupiter planets if 1 per cent of stars host such a companion and a typical hot Jupiter radius is ~1.2R_J. We find 24 transit candidates, 14 of which we can assign a period. We rule out the transiting planet model for 21 of these candidates using various robust arguments. For two candidates, we are unable to decide on their nature, although it seems most likely that they are eclipsing binaries as well. We have one candidate exhibiting a single eclipse, for which we derive a radius of 1.81+0.09-0.00R_J. Three candidates remain that require follow-up observations in order to determine their nature.

Evidence of jet precession in many galactic and extragalactic sources has been reported in the literature. Much of this evidence is based on studies of the kinematics of the jet knots, which depends on the correct identification of the components to determine their respective proper motions and position angles on the plane of the sky. Identification problems related to fitting procedures, as well as observations poorly sampled in time, may influence the follow-up of the components in time, which consequently might contribute to a misinterpretation of the data. In order to deal with these limitations, we introduce a very powerful statistical tool to analyse jet precession: the cross-entropy method for continuous multi-extremal optimization. Only based on the raw data of the jet components (right ascension and declination offsets from the core), the cross-entropy method searches for the precession model parameters that better represent the data. In this work we present a large number of tests to validate this technique, using synthetic precessing jets built from a given set of precession parameters. With the aim of recovering these parameters, we applied the cross-entropy method to our precession model, varying exhaustively the quantities associated with the method. Our results have shown that even in the most challenging tests, the cross-entropy method was able to find the correct parameters within a 1 per cent level. Even for a non-precessing jet, our optimization method could point out successfully the lack of precession.

Media convergence and newsroom integration have become industry buzzwords as the ideas spread through newsrooms around the world. In November 2007 Fairfax Media in Australia introduced the newsroom of the future model, as its flagship newspapers moved into a purpose-built newsroom in Sydney. News Ltd, the country’s next biggest media group, is also embracing multi-media forms of reporting. What are the implications of this development for journalism? This paper examines changes in the practice of journalism in Australia and around the world. It attempts to answer the question: How does the practice of journalism need to change to prepare not for the future, but for the likely present.

Early in November 2007 The Sydney Morning Herald, the Australian Financial Review and the Sun-Herald moved into a new building dubbed the ‘newsroom of the future’ at One Darling Island Road in Sydney’s Darling Harbour precinct. Phil McLean, at the time Fairfax Media’s group executive editor and the man in charge of the move, said three quarters of the entire process involved getting people to ‘think differently’ – that is, to modify their mindset so they could work with multi-media.

The new newsroom symbolised the culmination of a series of major changes at Fairfax. In August 2006 the traditional newspaper company, John Fairfax Ltd, changed its name to Fairfax Media to reflect its multi-platform future. In March 2007 Fairfax launched Australia’s first online-only daily publication in Queensland, brisbanetimes.com.au. In May 2007 Fairfax completed its merger with Rural Press to become the biggest media company in Australasia, with annual revenues of about $2.5 billion and market capitalisation of about $7 billion. Two months later Fairfax got even bigger when it acquired at least one radio station in all Australian capital cities plus television studios when it bought Southern Cross Broadcasting. Fairfax is expected to bid for one of the two digital television licences made available by the changes to media ownership laws promulgated in May 2007.

The aim in moving Fairfax from a print to a multi-platform company was to reach as large an audience as possible. ‘We have a total readership in print of over 4 million per day and online of over 5 million per month’, CEO David Kirk said at the time of the Rural Press merger. ‘Our brand of quality, independent, balanced journalism will serve and support more communities than ever’ (Kirk 2007). A few months earlier chairman Ron Walker had written in the company’s annual report: ‘Fairfax is evolving into a truly digital media company’ (2006: 2). Within five years Fairfax would be a significantly bigger Internet company that distributed its content ‘over more media’, Kirk wrote in the same report (2006: 5).

Kirk developed a three-pronged strategy. The first part of the strategy involved the need to ‘defend and grow our newspaper publishing businesses’ – that is, to consolidate and develop the existing newspapers, whose circulations were holding steady during the week and improving on Saturdays. The second part involved plans to ‘accelerate the revenue and earnings of our digital business’. The third part was ‘to build a digital media company for the twenty-first century’ (Fairfax annual report 2006: 3). In June 2007 Kirk appointed Tim Mannes project leader for the Fairfax Media-Rural Press integration. ‘The purpose of the integration work is to bring the two companies together and build what is truly Australasia’s leading media company’, Mannes wrote in a memo to all staff on 7 June 2007. ‘It’s vital throughout this process that we maintain continuity and momentum and protect the interests and needs of our customers’ (2007: 1).

The business model appears attractive. Kirk said Fairfax’s increased scale and diversity would mean it relied less on classified lineage advertising in major metropolitan newspapers, so it could ‘rapidly develop the best online response to changing media advertising patterns’. In the two years to 2006, online’s contribution to Fairfax’s profits had grown from 1 per cent to 14 per cent with ‘much more to come’. Online’s share of the national advertising pie had grown from 2 per cent in 2002 to 10 per cent in 2006 (Beverley 2007: 6) and had jumped to 14 per cent in 2007. Analysts said they were happy with Fairfax’s move ‘from a newspaper company to a media company’ and banks such as Credit Suisse upgraded their profits forecast (AFR 19 September 2007: 37).

Planning for the move to One Darling Island Road in Sydney’s Darling Harbour started early in 2006. Fairfax CEO David Kirk took personal responsibility. He and chairman Ron Walker visited integrated sites around the world, along with a group of editorial bosses. The favoured site was The Daily Telegraph in London, which embraced convergence from June 2006. CEO Murdoch McLennan hired a consultant from Ifra, Dr Dietmar Schantin, director of the Newsplex, to facilitate the move from mono-media to multi-media at The Telegraph. Schantin said change was less about new technologies and more about altering the established mindset. The focus must be on the audience: ‘The whole idea of audience orientation seems to be quite new for some newspapers. In the past it was more “we know what is good for our readers and so we distribute the content”.’ Newspapers were a service industry whose service was information and news, he said. Newspapers had to learn to ‘serve’ its audience with the things the audience wanted to know, on any appropriate platform. ‘We start from the audience. What they want is a very important point. That does not mean that a newspaper should just do what the audience wants. The newspaper [also] needs to stick
to its core values’ (Luft 2006, Coleman 2007: 5).

Tom Curley, CEO of the world’s biggest newsgathering organisation, Associated Press, gave an important speech to the annual Knight-Bagehot dinner in New York in November 2007. The news industry had come to a fork in the road and needed to take bold steps to secure the audiences and funding to support journalism’s essential role for both the economy and democracy, he said. Otherwise the media industry would find itself ‘on an ugly path to obscurity’. He similarly emphasised the need to serve the audience: ‘Our focus must be on becoming the very best at filling people’s 24-hour news needs. That’s a huge shift from the we-know-best, gatekeeper thinking. Sourcing, fact gathering, researching, storytelling, editing [and] packaging aren’t going away’
(Curley 2007).

Kirk appointed a ‘newsroom of the future’ committee from editorial (reporters and photographers), IT and HR. The committee initiated a study tour by editorial executives of leading integrated and converged newsrooms in the UK and the US in April 2007. This became known as the ‘Tier 1’ course and involved the editor and deputy editor of The Age, and the news editor of The Sydney Morning Herald. The Herald’s editor went to the annual conference of the World Association of Newspapers in Cape Town, South Africa in June 2007 because that event featured convergence as one of its main themes (PANPA Bulletin June 2007: 6). The committee designed a two-day awareness course for senior editorial managers, known as ‘Tier 2’, that was run in Sydney in July 2007. The ‘Tier 3’ program for all editorial staff started in August 2007 and this ‘multi-media awareness program’ continued until the end of the year. A ‘Tier 4’ course for about 10 per cent of editorial staff (about 40 journalists), where they learned a range of multi-media skills, was scheduled to start after the Beijing Olympics in 2008. The author facilitated most of the Tier 2 and 3 courses.

The Tier 3 and 4 courses have profound implications for journalism education in Australia because they represent the start of major changes to how journalists work in Australia. The process reflects evolution in newsroom practices around the world. In November 2006 Ifra, the international media research company, asked newspaper executives worldwide about their priorities for 2007. The survey attracted 240 responses from 43 countries and results appeared in January 2007. Integration, editorial convergence and cross-media strategies attracted the most attention. Four in five executives rated it one of their top priorities, and half made it their main priority in terms of allocating ‘significant’ funds (Ifra 2007: 34). Ifra repeated the survey in November 2007 and published the results in January 2008. Expanding web strategies was first on the list for 2008, just ahead of editorial convergence strategies, which topped the list in 2007. Improving video and audio content jumped 14 places, and mobile phone strategies leapt 9 places between 2007 and 2008 to be near the top of the list (Ifra 2008: 8).

Purpose – This paper aims to delineate the short- and long-run relationships between savings, real interest rate, income, current account deficits (CADs) and age dependency ratio in Fiji using cointegration and error correction models over the period 1968-2000.

Design/methodology/approach – The recently developed bounds testing approach to cointegration is used, which is applicable irrespective of whether the underlying variables are integrated of order one or order zero. Given the small sample size in this study, appropriate critical values were extracted from Narayan. To estimate the short- and long-run elasticities, the autoregressive distributed-lag model is used.

Findings – In the short- and long-run: a 1 per cent increase in growth rate increases savings by over 0.07 and 0.5 per cent, respectively; a 1 per cent increase in the CAD reduces savings rate by 0.01 and 0.02 per cent, respectively; and the negative coefficient on the real interest rate implies that the income effect dominates the substitution effect, while in the short-run the total effect of the real interest rate is positive, implying that the substitution effect dominates the income effect.

Originality/value – This paper makes the first attempt at estimating the savings function for the Fiji Islands. Given that Fiji's capital market is poorly developed, the empirical findings here have direct policy relevance.

This paper examines the causal relationship between electricity consumption, exports and gross domestic product (GDP) for a panel of Middle Eastern countries. We find that for the panel as a whole there are statistically significant feedback effects between these variables. A 1 per cent increase in electricity consumption increases GDP by 0.04 per cent, a 1 per cent increase in exports increases GDP by 0.17 per cent and a 1 per cent increase in GDP generates a 0.95 per cent increase in electricity consumption. The policy implications are that for the panel as a whole these countries should invest in electricity infrastructure and step up electricity conservation policies to avoid a reduction in electricity consumption adversely affecting economic growth. Further policy implications are that for the panel as a whole promoting exports, particularly non-oil exports, is a means to promote economic growth and that expansion of exports can be realized without having adverse effects on energy conservation policies.

Purpose – This paper aims to estimate a disaggregated import demand model for Fiji using relative prices, total consumption, investment expenditure and export expenditure variables for the period 1970 to 2000.

Design/methodology/approach – The recently developed bounds testing approach to cointegration to test for a long run relationship is used, while the autoregressive distributed lag model is used to estimate short run and long run elasticities. These methodologies are shown to perform well in small sample sizes, particularly given that the bounds F-test critical values for small sample sizes generated by Narayan in 2004 and 2005 are used.

Findings – Amongst the key results it is found: a long run cointegration relationship among the variables when import demand is the dependent variable; and import demand to be inelastic and statistically significant at the 1 per cent level with respect to all the explanatory variables in both the long-run and the short-run.

Originality/value – The disaggregated import demand model estimated here provides a complete picture of the determinants of Fiji's imports. This model can be used by Fijian policy makers to draw pertinent policies and forecast import demand for Fiji.

The aim was to determine the extent of daily disposable contact lens prescribing worldwide and to characterise the associated demographics and fitting patterns. Up to 1,000 survey forms were sent to contact lens fitters in up to 40 countries between January and March every year for five consecutive years (2007 to 2011). Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Survey data collected since 1996 were also analysed for seven nations to assess daily disposable lens fitting trends since that time. Data were collected in relation to 97,289 soft lens fits, of which 23,445 (24.1 per cent) were with daily disposable lenses and 73,170 (75.9 per cent) were with reusable lenses. Daily disposable lens prescribing ranged from 0.6 per cent of all soft lenses in Nepal to 66.2 per cent in Qatar. Compared with reusable lens fittings, daily disposable lens fittings can be characterised as follows: older age (30.0 ± 12.5 versus 29.3 ± 12.3 years for reusable lenses); males are over-represented; a greater proportion of new fits versus refits; 85.9 per cent hydrogel; lower proportion of toric and presbyopia designs and a higher proportion of part-time wear. There has been a continuous increase in daily disposable lens prescribing between 1996 and 2011. The proportion of daily disposable lens fits (as a function of all soft lens fits) is positively related to the gross domestic product at purchasing power parity per capita (r(2) = 0.55, F = 46.8, p < 0.0001). The greater convenience and other benefits of daily disposable lenses have resulted in this modality capturing significant market share. The contact lens field appears to be heading toward a true single-use-only, disposable lens market.

Government transfers to individuals and families play a central role in the Brazilian social protection system, accounting for almost 14 per cent of GDP in 2009. While their fiscal and redistributive impacts have been widely studied, the macroeconomic effects of transfers are harder to ascertain. We constructed a Social Accounting Matrix (SAM) for 2009 and estimated short-term multipliers for seven different government monetary transfers . The SAM is a double-entry square matrix depicting all income flows in the economy. The data were compiled from the 2009 Brazilian National Accounts and the 2008/2009 POF, a household budget survey. Our SAM was disaggregated into 56 sectors, 110 commodities, 200 household groups and seven factors of production (capital plus six types of labor, according to schooling). Finally, we ran a set of regressions to separate household consumption into ‘autonomous’ (or ‘exogenous’) and ‘endogenous’ components. More specifically, we are interested in the effects of an exogenous injection into each of the seven government transfers outlined above. All the other accounts are thus endogenous. The so-called demand ‘leaks’ are income flows from the endogenous to exogenous accounts. Leaks—such as savings, taxes and imports—are crucial to determine the multiplier effect of an exogenous injection, as they allow the system to go back to equilibrium. The model assumes that supply is perfectly elastic to demand shocks. It assumes that the families’ propensity to save and consumption profile are fixed—that is, rising incomes do not provoke changes in behaviour. The multiplier effects of the on GDP corresponds to the growth in GDP resulting from each additional dollar injected into each transfer seven government transfers. If the government increased Bolsa Família expenditures by 1 per cent of GDP, overall economic activity would grow by 1.78 per cent, the highest effect. The Continuous Cash Benefit, comes second. Only three transfers— the private-sector and public servants’ pensions and FGTS withdrawals—had multipliers lower than unity. The multipliers for other relevant macroeconomic aggregates—household and total consumption, disposable income etc. —reveal a similar pattern. Thus, under the stringent assumptions of our model, we cannot reject the hypothesis that government transfers targeting poor households, such as the Bolsa Família, help foster economic expansion. Naturally, it should be stressed that the multipliers relate marginal injections into government transfers to short-term economic performance either real growth, or inflation if there is no idle capacity which is also useful to analyze. In the long term, there is no doubt that what truly matters is the growth of the country’s productive capacity.

Purpose: The purpose of this paper is to determine the effects of isolated soy glycinin (11S) on lipid metabolism in animals subjected to a hypercholesterolemic diet. Design/methodology/approach: Male Wistar rats were kept in individual cages under appropriate conditions. The animals were divided into three groups (n=9): normal diet (STD) given a diet containing casein as protein source, recommended in AIN-93M; hypercholesterolemic (HC) fed a normal diet with 1 per cent cholesterol and 0.5 per cent cholic acid; and hypercholesterolemic+glycinin (HC+11S), fed a hypercholesterolemic diet, plus 11S soy protein (300 mg/kg/day), dissolved in saline and administered by gavage. After 28 days, the animals were sacrificed and blood and liver removed for biochemical analysis of total cholesterol (TC), HDL-cholesterol (HDL-C) and triglycerides (TG) in the plasma, hepatic TC and TG. Findings: A single daily dose of glycinin given to the hypercholesterolemic group demonstrated its functional role, particularly in raising HDL-C and reducing triglycerides in the liver. Originality/value: This study demonstrates the action of the 11S globulin in soybean as a serum lipid lowering agent, in addition to its nutritional properties, especially in raising the HDL-C. © Emerald Group Publishing Limited.
