Information, Uncertainty, and Subjective Entitlements in Bargaining More often than not production processes are the joint endeavor of people having different abilities and productivities. Such production processes and the associated surplus production are often not fully transparent in the sense that the relative contributions of involved agents are blurred; either by lack of information about...

BACKGROUND The USee device is a new self-refraction tool that allows users to determine their own refractive error. We evaluated the ease of use of USee in adults, and compared the refractive error correction achieved with USee to clinical manifest refraction. METHODS Sixty adults with uncorrected visual acuity <20/30 and spherical equivalent between -6.00 and +6.00 diopters completed manifes...

Evaluation measures, objective and subjective, are used to assist users in finding interesting association rules. Objective measures are more general, but they can be insufficient because they do not consider user’s and domain features. However, getting user’s knowledge and interest needed to calculate subjective measures can be a difficult task. Thus, this work presents a methodology to identi...

Three major puzzles, described later in this section, have captured the attention of macroeconomic finance: the equity-premium, riskfreerate and equity-volatility puzzles. A common strand of these three asset-return puzzles is that markets are behaving as if investors fear some unknown hidden randomness that isn’t obvious from the data. People are acting in the aggregate like there is much more...

Background: The purpose of this research was to investigate the diurnal effect Ramadan fasting on amplitude accommodation and anterior segment parameters in visually healthy participants.Materials Methods: study included 68 individuals, aged 26–42 years. subjective measured using "minus lens" technique. Corneal refraction (K1, K2, Kmax), central corneal thickness, volume, chamber depth were eva...

Cortical activity, as recorded via electroencephalography, has been linked to the refractive error of an individual. It is however unclear which optical metric modulates this response. Here, we measured simultaneously brain activity and retinal defocus a visual stimulus perceived through several values spherical blur. We found that, contrary existing literature on topic, cortical response funct...

We investigate people’s attitudes towards the possible use of mobile negotiation support systems (NSS) in different social contexts and the consequences for their design. For that purpose we developed an online survey based on existing models of technology acceptance. In the questionnaire we showed five filmed scenarios of NSS use contexts. The data collected from 120 respondents, showed (a) th...

BACKGROUND Photonic crystals are artificial structures that have periodic dielectric components with different refractive indices. Under certain conditions, they abnormally refract the light, a phenomenon called negative refraction. Here we experimentally characterize negative refraction in a one dimensional photonic crystal structure; near the low frequency edge of the fourth photonic bandgap....

PURPOSE To study the relationship between baseline spherical equivalents (SphE) of refraction and prevalent as well as incident age-related maculopathy (pARM and iARM, respectively). METHODS The study was performed as part of the Rotterdam Study, a population-based, prospective cohort study. The SphE (in diopters), measured with autorefraction and subjective optimization, was recorded in 6209...

PURPOSE To report the 9-12-month outcomes of a novel procedure for reduction of low myopia through epithelium-on photorefractive intrastromal cross-linking (PiXL) with customized control of topographic distribution of ultraviolet (UV)-fluence. METHOD Myopic patients with normal (non-ectatic) corneas underwent the PiXL procedure for reduction of low myopia. PiXL treatments were delivered throu...
