Young adolescents are quickly becoming avid users of social networking sites (SNSs); however, little is known regarding how they use these sites. The goal of the present study was to examine the extent to which young adolescents use SNSs, with whom they connect via these sites, and whether SNS use disrupts daily functioning. Among 268 middle-school students surveyed, 63% reported having their o...

Methods: Patient records were identified from a specialty contact lens practice. Data were obtained from myopic patients who were prescribed Ortho-K wear. Demographic data at baseline included age at commencement of Ortho-K and ethnicity. Clinical data recorded at baseline and at years 1, 2 and 3 included subjective refraction, corneal topography, corneal curvature, axial length, pupil size, an...

We experimentally explore the effects and interactions of three variables considered important when bargaining over a jointly produced surplus: performance information, production uncertainties when translating performance into output, and subjective entitlements derived from the production process. We find that without performance information subjective entitlements are mostly mutually consist...

Purpose: We propose in this paper to analyze what are the factors that influence knowledge transfer both intra and intergenerational in family firms. The main objective is to establish a framework that can be used later in empirical research, although we maintain a completely theoretical approach in this paper Design/methodology/approach: This study, which is a comprehensive framework character...

Abstract Purpose While there are numerous studies comparing open-view autorefractors to subjective refraction or other autorefractors, most between closed and autorefraction tend focus on children rather than young adults. The aim of this study was determine the concordance in non-cycloplegic refractive error two modern objective autorefractors: closed-view monocular Topcon TRK-2P binocular Gra...

Purpose: To clinically evaluate a new extended depth of focus intraocular lens (ISOPURE, PhysIOL) with optic design modification based on unique polynomial concept to improve intermediate vision while keeping the quality distance equal monofocal lens. Methods: 18 patients (11 female, 7 male, mean age 69.4 years) bilateral cataract and regular corneal astigmatism ? 1.0 D underwent surgery ISOPUR...

This article adopts a critical sociological perspective to examine the expectations surrounding the uses of social networking sites (SNSs) articulated in the domain of clinical literature. This emerging body of articles and commentaries responds to the recent significant growth in SNS use, and constitutes a venue in which the meanings of SNSs and their relation to health are negotiated. Our ana...

The project management discipline is expanding within many engineering activities. This discipline can facilitate strivings toward successful accomplishment of an engineering project. Therefore, many academic institutes teach the “project management” program. This study presents a novel approach that educates engineering students to become successful project managers based on contextual learnin...

Ambivalence, the presence of positive and negative reactions toward an object, typically involves the subjective experience of conflict. We investigate the role that the perceived validity of each side of an ambivalent attitude plays in producing subjective ambivalence (SA). Consistent with the metacognitive model of attitudes, we demonstrated that SA is reduced when people doubt either the pos...
