...S Afr Optom 2010 69(2) 86-92 Refractive error in school children in Agona Swedru, Ghana G O Ovenseri-Ogbomo* and R Assien† *Department of Optometry, University of Cape Coast, Ghana †Eye Unit, Regional Hospital, Koforidua, Ghana * Received 25 September 2009; revised version accepted 9 June 2010 Abstract Uncorrected refractive errors remains a public health problem among different population groups. Among schoolchildren, uncorrected refractive errors have a considerable impact on learning and academic achievement especially in underserved and under-resourced communities. A school based cross-sectional study was carried out to estimate the prevalence and distribution of refractive error among schoolchildren in the Agona Swedru municipality of Central Region of Ghana. 637 schoolchildren aged 11-18 years old were randomly selected for the study. Non-cycloplegic refraction was performed on each child who failed the reading test. Hyperopia was defined as spherical power of ≥ + 0.75 D, myopia as ≤ – 0.50 D and astigmatism as a cylindrical power of ≤ – 0.50 D. Of the children examined, only 13.3% had previously had an eye examination. Introduction Uncorrected refractive errors remains a public health problem among different population groups. Among schoolchildren, it has a considerable impact on learning and academic achievement especially in underserved and under-resourced communities. Uncorrected refractive errors in schoolchildren and its impact on academic achievement have...

...The Latitudinal Diversity Gradient Hypothesis: the state of knowledge Biogeography Spring 2013, Term Paper Title: Latitudinal Diversity Gradient Hypothesis, the state of knowledge By Schibon 1. Introduction Latitudinal gradients in species diversity are generally understood to be increases in the number of species from high (cold-temperate) to low (warm) latitudes (Rohde, 2011). As early as 1807, von Humboldt provided the first formulation for this hypothesis (based on climate) to explain latitudinal gradients of richness (Hawkins 2001) which has remained one of the key questions in Evolutionary Ecology. No single pattern of biodiversity has fascinated ecologists more than the increase of richness toward the Tropics (Pianka 1966; Rohde 1992; Rosenzweig 1995; Gaston and Blackburn 2000). Still, there is an astonishing lack of consensus about the mechanisms leading to this spatial variation in diversity (Hillebrand, 2004). As the search for a primary cause to this latitudinal gradient has been hampered by the increase number of hypotheses (Pianka 1966; Rohde 1992), their interdependence (Currie 1991; Gaston and Blackburn 2000), and the lack of rigorous falsification (Currie et al. 1999), it makes sense to assess the current state of knowledge on this issue. The current paper aims at updating on the current state of knowledge concerning the latitudinal diversity gradient particularly through reviewing the most dominant hypotheses and theories striving...

...1. Introduction ‘Knowledge is power’, an old saying from Francis Bacon, which is considered as a true statement that has been recognised for a long time (Greco, 1993; Nielsen and Rasmussen, 2011). Especially, in recent 20 years, the interest and importance of knowledge in organisations has been increased remarkably in both theoretically and practically (Cheema, 2010; Knight and Howes, 2003; Rasmussen and Nielsen, 2011). The reason is revealed by Migdadi (2009) and Politis (2005), in the new economy, the intangible resource, knowledge has become the foundation of organisational competitiveness compared to tangible assets. In other words, the traditional driving factors of production, including, land, labour and capital have turned into the secondary resources as knowledge become the primary source of power in production within the contemporary economy. The work of Rasmussen and Nielsen (2011) reveal that intangible resource is regarded as a typical feature of knowledge, which can build capabilities for both organisations and individuals, consequently, in this new economy, also can be called knowledge-based economy made knowledge become strategically important to provide sustain competitive advantage for enterprises, especially in high technology and bioengineering sectors (Niu, 2010). Knowledge therefore has emerged as a main source of power as well as core competency in today’s emerging economies. However, new possibilities and threads are constantly taken place to challenge...

...Information & Management 41 (2004) 805–825 eAirlines: strategic and tactical use of ICTs in the airline industry Dimitrios Buhalis* Centre for eTourism Research (CeTR), School of Management, University of Surrey, Guildford, England GU2 7XH, UK Received 16 June 2002; received in revised form 26 April 2003; accepted 6 August 2003 Available online 13 November 2003 Abstract Information Communication Technologies (ICTs) have revolutionised the entire business world. The airline industry in particular has fostered a dependency on technology for their operational and strategic management. Airlines were early adopters of ICTs and have a long history of technological innovation, in comparison to many other travel and tourism businesses. This paper discusses comprehensive research, including exploratory research with airline executives, using qualitative methods to examine the use of ICTs in the contemporary airline industry and to discuss recent developments in the industry. The work demonstrated that the airline industry was using the Internet to improve its distribution strategy and reduce costs; it also used Intranets and internal systems to develop tactical and strategic management. In addition, Extranets were being gradually used for communicating with partners and to support business-to-business (B2B) relationships. The effort demonstrated that ICTs will be critical for the strategic and operational management of airlines and will directly affect the future competitiveness of...

...Resource Markets WP-RM-18 Recent Developments in Transaction Cost Economics Sophia Ruester January 2010 Chair for Energy Economics and Public Sector Management Electronic copy available at: http://ssrn.com/abstract=1535903 Recent Developments in Transaction Cost Economics Sophia Ruester1 Abstract This working paper provides a summary on transaction cost economics (TCE) and recent developments thereof. After an introductory discussion of TCE’s role within the field of New Institutional Economics, a critical analysis of the contribution of the existing body of empirical literature is conducted. In recent years, researchers have continued to develop and extend TCE. Williamson (1991b) introduces the shift parameter framework which investigates how the optimal choice of governance changes in response to dynamics in the institutional environment. Nickerson (1997) develops the positioning-economizing perspective arguing that decisions regarding market position, resource investments, and governance mode are interdependent and determined simultaneously. A number of authors came up with an increasing interest in relational institutional arrangements arguing that TCE may overstate the desirability of complex long-term contracts and vertical integration in exchange settings where a substantial hold-up potential is present.
