A method for calculating the crowding-out effect in sport mega-event impact studies: The 2010 FIFA World Cup

2011

Tourist expenditures constituted the largest part of the economic impact of South Africa's 2010 FIFA Football World Cup. However, limited air transport capacity and increased accommodation prices may have led to crowding-out effects. Until now, crowding-out could only be considered by using econometric modelling based on data of inbound arrival or accommodation statistics. This paper suggests a methodology for measuring the crowding-out effect precisely. It is based on the available statistics in South Africa and is applicable at province level. An important innovation is to distinguish crowding-out from time-switching effects. The paper explains the theoretical framework of crowding-out as…

Changes in anterior chamber eye during accommodation as assessed using a Dual Scheimpflug system

2014

Purpose: To study the changes in anterior chamber depth (ACD), anterior chamber angle (ACA), and pupil diameter (PD) during accommodation. Methods: Eighty eyes of 80 subjects, aged 22 to 40 years, were included. The rotating Dual Scheimpflug and a Placido disc system (Galilei G4, Ziemer Ophthalmic Systems AG, Switzerland) was used to measure the changes in ACD, ACA, and PD during accommodation. ACD measurement was taken for the central zone and for 4 more positions, each in different orientation (nasal, superior, temporal and inferior), 4 mm away from the centre. ACA was measured for the whole eye as well for the nasal, superior, temporal, and inferior quadrants. These metrics were obtained…

An examination of the impact of care giving styles (accommodation and skilful communication and support) on the one year outcome of adolescent anorex…

2016

Abstract Background The cognitive interpersonal model predicts that parental caregiving style will impact on the rate of improvement of anorexia nervosa symptoms. The study aims to examine whether the absolute levels and the relative congruence between mothers' and fathers' care giving styles influenced the rate of change of their children's symptoms of anorexia nervosa over 12 months. Methods Triads ( n =54) consisting of patients with anorexia nervosa and both of their parents were included in the study. Caregivers completed the Caregiver Skills scale and the Accommodation and Enabling Scale at intake. Patients completed the Short Evaluation of Eating Disorders at intake and at monthly in…

Changes in the anterior chamber during accommodation assessed with a Scheimpflug system.

2014

Purpose To study changes in the anterior chamber depth (ACD), anterior chamber angle, and pupil diameter with accommodation. Setting University of Valencia, Valencia, Spain. Design Evaluation of diagnostic technology. Methods A rotating Scheimpflug camera (Pentacam HR) was used to measure changes in the ACD, anterior chamber angle, and pupil diameter with accommodation. Peripheral ACD was measured at the corneal center and 2.0 mm away from it in the nasal, superior, temporal, and inferior directions. The anterior chamber angle was computed as the mean anterior chamber angle of the entire eye. All measurements were obtained with accommodation stimuli ranging from +1.0 to −4.0 diopters (D) in…

Implantable collamer lens and femtosecond laser for myopia: comparison using an adaptive optics visual simulator.

2014

Purpose: To compare optical and visual quality of implantable collamer lens (ICL) implantation and femtosecond laser in situ keratomileusis (F-LASIK) for myopia. Methods: The CRX1 adaptive optics visual simulator (Imagine Eyes, Orsay, France) was used to simulate the wavefront aberration pattern after the two surgical procedures for -3-diopter (D) and -6-D myopia. Visual acuity at different contrasts and contrast sensitivities at 10, 20, and 25 cycles/degree (cpd) were measured for 3-mm and 5-mm pupils. The modulation transfer function (MTF) and point spread function (PSF) were calculated for 5-mm pupils. Results: F-LASIK MTF was worse than ICL MTF, which was close to diffraction-limited MT…

Pseudoaccommodating intraocular lens implantation in patients with irregular nonreactive pupils.

2007

We report 3 patients implanted with the AcrySof ReSTOR pseudoaccommodating intraocular lens (IOL) who had irregular nonreactive pupils as a consequence of pupil stretching during phacoemulsification. Despite the pupils, the visual acuity at distance and near was not compromised. The outcome in these cases suggests that an irregular nonreactive pupil is not an exclusion criterion for pseudoaccommodating IOL implantation.

Objective Amplitude of Accommodation Computed from Optical Quality Metrics Applied to Wavefront Outcomes

2009

Purpose: We studied the accuracy and precision of 32 objective wavefront methods for finding the amplitude of accommodation obtained in 180 eyes. Methods: Ocular accommodation was stimulated with 0.5 D steps in target vergence spanning the full range of accommodation for each subject. Subjective monocular amplitude of accommodation was measured using two clinical methods, using negative lenses and with a custom Badal optometer. Results: Both subjective methods gave similar results. Results obtained from the Badal optometer where used to test the accuracy of the objective methods. All objective methods showed lower amplitude of accommodation that the subjective ones by an amount that varied …

Generation Y Travelers’ Intentions to Book Airbnb Accommodation: An Abstract

2017

Sharing economy is affecting the global economy with increasing scale, as customers can exchange commodities in an organized way under the help of an enormous number of online platforms (Balck and Cracau 2015). In the context of holiday accommodation, Airbnb’ s growth has been stunning as now it has more available rooms than hotel giants like Marriott and Hilton (Weed 2015). In fact, research has highlighted Airbnb’s potential to disrupt the traditional accommodation sector (Guttentag 2013). Given the importance of Airbnb, it is crucial to examine which factors affect intentions to book an accommodation on Airbnb. This study proposes an integrative model based on the theory of reasoned acti…
