Modeling equity market integration using smooth transition analysis:a study of Eastern European stock markets

This paper assesses the extent to which the equity markets of Hungary, Poland the Czech Republic and Russia have become less segmented. Using a variety of tests it is shown there has been a consistent increase in the co-movement of some Eastern European markets and developed markets. Using the variance decompositions from a vector autoregressive representation of returns it is shown that for Poland and Hungary global factors are having an increasing influence on equity returns, suggestive of increased equity market integration. In this paper we model a system of bivariate equity market correlations as a smooth transition logistic trend model in order to establish how rapidly the countries of Eastern Europe are moving away from market segmentation. We find that Hungary is the country which is becoming integrated the most quickly. © 2005 ELsevier Ltd. All rights reserved.

Conjunctival UV autofluorescence - prevalence and risk factors

Purpose: Autofluorescence of ultraviolet (UV) light has been shown to occur in localised areas of the bulbar conjunctiva, which map to active cellular changes due to UV and environmental exposure. This study examined the presence of conjunctival UV autofluorescence in eye care practitioners (ECPs) across Europe and the Middle East and its associated risk factors. Method: Images were captured of 307 ECPs right eyes in the Czech Republic, Germany, Greece, Kuwait, Netherlands, Sweden, Switzerland, United Arab Emirates and the United Kingdom using a Nikon D100 camera and dual flash units through UV filters. UV autofluorescence was outlined using ImageJ software and the nasal and temporal area quantified. Subjects were required to complete a questionnaire on their demographics and lifestyle including general exposure to UV and refractive correction. Results: Average age of the subjects was 38.5±12.2 years (range 19-68) and 39.7% were male. Sixty-two percent of eyes had some conjunctival damage as indicated by UV autofluorescence. The average area of damage was higher (p=0.005) nasally (2.95±4.52mm2) than temporally (2.19±4.17mm2). The area of UV damage was not related to age (r=0.03, p=0.674), gender (p=0.194), self-reported sun exposure lifestyle (p>0.05), geographical location (p=0174), sunglasses use (p>0.05) or UV-blocking contact lens use (p>0.05), although it was higher in those wearing contact lenses with minimal UV-blocking and no spectacles (p=0.015). The area of UV damage was also less nasally in those who wore contact lenses and spectacles compared to those with no refractive correction use (p=0.011 nasal; p=0.958 temporal). Conclusion: UV conjunctival damage is common even in Europe, Kuwait and UAE, and among ECPs. The area of damage appears to be linked with the use of refractive correction, with greater damage nasally than temporally which may be explained by the peripheral light focusing effect.

An optical fiber Bragg grating tactile sensor

Tactile sensors are needed for many emerging robotic and telepresence applications such as keyhole surgery and robot operation in unstructured environments. We have proposed and demonstrated a tactile sensor consisting of a fibre Bragg grating embedded in a polymer "finger". When the sensor is placed in contact with a surface and translated tangentially across it measurements on the changes in the reflectivity spectrum of the grating provide a measurement of the spatial distribution of forces perpendicular to the surface and thus, through the elasticity of the polymer material, to the surface roughness. Using a sensor fabricated from a Poly Siloxane polymer (Methyl Vinyl Silicone rubber) spherical cap 50 mm in diameter, 6 mm deep with an embedded 10 mm long Bragg grating we have characterised the first and second moment of the grating spectral response when scanned across triangular and semicircular periodic structures both with a modulation depth of 1 mm and a period of 2 mm. The results clearly distinguish the periodicity of the surface structure and the differences between the two different surface profiles. For the triangular structure a central wavelength modulation of 4 pm is observed and includes a fourth harmonic component, the spectral width is modulated by 25 pm. Although crude in comparison to human senses these results clearly shown the potential of such a sensor for tactile imaging and we expect that with further development in optimising both the grating and polymer "finger" properties a much increased sensitivity and spatial resolution is achievable.

Outsourcing: a Theoretical Viewpoint

Outsourcing or offshoring as it is now known has been around for many decades. In the beginning, it was only very peripheral activities that were outsourced, i.e. blue-collar (lower skilled) work but this is now all changing with the outsourcing of white-collar jobs. The digital revolution, the falling costs of transport and telecom costs and the opening up of the global economy helped the outsourcing market. For companies going down or contemplating the road of outsourcing there are both potential benefits and challenges, for example, the type of outsourcing they want to get involved in, and the country they want to outsource to. Outsourcing can potentially happen anywhere in the world where the costs are lower and the quality higher. The main places that have been used for outsourcing have been India, China, Ireland, South-East Asia, Russia, Mexico and the Czech Republic. The research currently underway is initially focusing on a literature review of current outsourcing applications in the market place. From this literature review, a questionnaire is being developed to assess the impact Outsourcing has on businesses. This research focuses on the Irish Market place.

Editorial

This time of year we look back at the year that has passed and make plans for the next year. I like to reflect on things that I have learnt and people that I have met, especially those who facilitated that learning. In 2009 I went to various conferences, The BCLA conference in Manchester, The Romanian Optical Society meeting in Brasov, Transylvania (where the university is actually on Vlad Tepes Street), The European Council for Optometry and Optics (ECOO) in Brno, Czech Republic, The American Academy of Optometry (AAO) in Orlando USA, The International Association of Contact Lens Educators (IACLE) meeting in Tianjin China and finally The Vereinigung Deutscher Contactlinsen-Spezialisten (VDCO) meeting in Jena. All were interesting places and thoroughly all were enjoyable conferences with their own highlights but I wanted to focus on Jena and one person I met there and his inspirational search for knowledge and the contributions he made in the field of contact lenses. Jena itself is a fascinating place and should be on the ‘must visit’ list of anyone involved in eye care. It is the birth place of Carl Zeiss of course and where he started his company. It is also the birth place of Ernst Abbe (physicist and optometrist and expert lens maker), and Otto Schott (chemist and technologist who made high quality glass. There are many road signs bearing witness to these famous pioneers. The optical museum is worth spending a few hours looking around too. I was invited to speak at the VDCO at the kind invitation from colleagues at the Jena School of Optometry, Professor Wolfgang Sickenberger and Professor Sebastian Marx. At this meeting I met 87-year-old Willi KAUE who was being awarded the Adolf Wilhelm Müller-Welt prize by the VDCO for contribution to contact lenses over his 60-year career. At the age of 15 Willi Kaue took up an apprenticeship to become an Optician in Germany in 1937. At this time he first heard about the scleral glass lenses made by the Carl Zeiss Company in Jena. This started his lifelong fascination which was to become his passion but not yet his career. During the war he was enlisted into military service but immediately after was back to his former career. In 1950 Willi corrected his own 3.5 dioptres of myopia with a plastic scleral lens. His fascination strengthened as for the first time he himself could experience a wider field of view than his spectacles gave him, less aberrations and less retinal minification. He also appreciated the fact that contact lenses did not cause pressure on the nose or ears and did not slide down his nose plus remained optically centred with his eye movements. He decided that form now on he would make fitting contact lenses his career. He travelled to London to learn more about contact lenses and how to fit them but initially did not find many willing teachers and to start with became largely self-taught. He wanted to know how to make scleral lenses. So far he only knew that pulverized polymethyl methacrylate (PMMA) was pressed and moulded. In 1951 he met Berlin optician Otto Marzock. He made his only scleral lenses from using military PMMA windshields. His process involved lathe cutting the lenses and resulted in lenses that were thinner than moulded ones. Willi developed a manufacturing method, using a rotary diamond drill, starting form the outer edge and towards the centre at a constant cut speed. This enabled him to make more reproducible lenses and in less time. His enthusiasm in the field was clear from the travels he made in the pursuit of advancement - travelling around Europe, South America, North America and Asia. In 1963 he visited George Nissel in Hemel Hempstead, England. Constantly thriving towards innovations Willi came across the new Naturalens from the USA made from HEMA at a congress in Marseille in 1969. Amongst his contributions to the field, was his own technique of fitting ocular prosthetics, using an alginate impression of the orbit. I was fortunate enough to have dinner with Willi Kaue and learnt more about his fascinating career through the patient interpreting skills of Hilmar Bussacker (the 2008 winner of the same award and the 2007 winner of the European Federation of the Contact Lens and IOL Industries Award). I look forward to 2010 with eager anticipation as to what I may learn and who I might meet!!! Copyright © 2009 British Contact Lens Association. Published by Elsevier Ltd. All rights reserved.
