Shopping is a social activity that people enjoy doing with friends and close ones. In this paper we name such joint shopping activity performed by two or more people together as “collaborative shopping”, and investigate the possible means of carrying it out online. We start with identifying the objectives of collaborative shopping (i.e., socializing and purchasing) and propose website features ...

BACKGROUND Teleophthalmology, particularly real-time video consultation, holds great potential in Australia and similar countries worldwide, where geography, population and medical workforce distribution make it difficult to provide specialist eye services outside of major cities. Assessment and referrals from rural optometrists are vital to the success of teleophthalmology. While there is good...

Given a k-ary predicate P, a random instance of a constraint satisfaction problem with predicate P (CSP(P)) is a set of m constraints on n variables. Each constraint is P applied to k random literals. Such an instance is unsatisfiable with high probability when m >> n. Refutation is certifying that a given randomly chosen instance is unsatisfiable. This task has applications in cryptography, ha...

OBJECTIVES This study aimed to (1) measure the degree of patient satisfaction among the clinical and nonclinical dental services offered at specialty dental centers and (2) investigate the factors associated with the degree of overall satisfaction. MATERIALS AND METHODS Four hundred and ninety-seven participants from five dental centers were recruited for this study. Each participant complete...

background: infertility is a global public health issue and may adversely affect life satisfaction. one of the most widely instruments used to assess life satisfaction is the satisfaction with life scale (swls). objective: the objective of this study was to examine the psychometric properties of the swls in iranian infertile women. materials and methods: in this descriptive cross-sectional stud...

The article proposes a conceptual model for understanding key factors that shape satisfaction with the services offered by South African advertising agencies. In particular, the model draws together two distinct approaches: (1) service quality associated with service output and performance, and (2) relational exchanges between advertisers and advertising agencies. Insight and perspectives from ...

This paper propose a new type of Fuzzy CSP(Constraint Satisfaction Problem) that have a mixture of discrete and continuous domains, and a Spread-Repair algorithm. In traditional CSP and Fuzzy CSP, values for the variables are chosen from the discrete domains. However, this is often inconvenient when one wants to express real world problems. We show that this model, called HDFCSP(Hybrid Domain F...

Consider random hypergraphs on n vertices, where each k-element subset of vertices is selected with probability p independently and randomly as a hyperedge. By sparse we mean that the total number of hyperedges is O(n) or O(n lnn). When k = 2, these are exactly the classical Erdös-Rényi random graphs G(n, p). We prove that with high probability, hinge width on these sparse random hypergraphs ca...

BACKGROUND Satisfaction with birth care is part of quality assessment of care. The aim of this study was to investigate possible differences in satisfaction with intrapartum care among low-risk women, randomized to a midwifery unit or to an obstetric unit within the same hospital. METHODS Randomized controlled trial conducted at the Department of Obstetrics and Gynecology, Østfold Hospital Tr...

Studies on public transit have emphasized the role of passenger satisfaction with service quality in travel choice decisions and indicated that satisfaction depends on various service attributes. Few studies have, however, systematically examined the underlying relationships among service attributes to assess their influence on passenger overall satisfaction. Therefore, to contribute to this ra...
