OBJECTIVE To describe dietary habits in the Turks and Caicos Islands. DESIGN AND METHODS Food frequency questionnaires were administered to female-household-heads of 144 households randomly selected from three islands' voter's lists (Grand Turk [n = 48], Providenciales [n = 46] and Middle Caicos [n = 50]). Data were collected on the distribution of (a) Households among Levels 0 - 7 of a Food ...

Purpose. To evaluate the feasibility of using Mechanical Turk as a massively parallel platform to perform manual segmentations of macular spectral domain optical coherence tomography (SD-OCT) images using a MapReduce framework. Methods. A macular SD-OCT volume of 61 slice images was map-distributed to Amazon Mechanical Turk. Each Human Intelligence Task was set to $0.01 and required the user to...

Researchers, technology reviewers, and governmental agencies have expressed concern that automation may necessitate the introduction of added displays to indicate vehicle intent in vehicle-to-pedestrian interactions. An automated online methodology for obtaining communication intent perceptions for 30 external vehicle-to-pedestrian display concepts was implemented and tested using Amazon Mechan...

Crowdsourcing is becoming more and more important for commercial purposes. With the growth of crowdsourcing platforms like Amazon Mechanical Turk or Microworkers, a huge work force and a large knowledge base can be easily accessed and utilized. But due to the anonymity of the workers, they are encouraged to cheat the employers in order to maximize their income. Thus, this paper we analyze two w...

Designers of human computation systems often face the need to aggregate noisy information provided by multiple people. While voting is often used for this purpose, the specific voting methods that are employed are typically naı̈ve. The theory of social choice provides powerful tools for exactly these settings. We conduct experiments on Amazon Mechanical Turk which demonstrate empirically that mo...

Nonverbal behaviors play an important role in communication for both humans and social robots. However, adding contextually appropriate animations by hand is time consuming and does not scale well. Previous researchers have developed automated systems for inserting animations based on utterance text, yet these systems lack human understanding of social context and are still being improved. This...

Sum mary Urticarial disease is characterized by transient erythematous, swelling and pruritic lesions. Classification of the disease as acute and chronic urticeria provide a comprehensive approach to detect the etiological factors and estimate the prognosis. In this paper, clinical classification of urticeria, pathogenesis, related factors with disease and therapy options were reviewed. (Turk A...

The efficient functioning of markets and institutions assumes a certain degree of honesty from participants. In labor markets, for instance, employers benefit from employees who will render meaningful work, and employees benefit from employers who will pay the promised amount for services rendered. We use an established method for detecting dishonest behavior in a series of experiments conducte...

In the field of machine translation, automatic metrics have proven quite valuable in system development for tracking progress and measuring the impact of incremental changes. However, human judgment still plays a large role in the context of evaluating MT systems. For example, the GALE project uses humantargeted translation edit rate (HTER), wherein the MT output is scored against a post-edited...

The development of Internet technology has facilitated the emergence of online marketplace for various kinds of tasks (e.g., Amazon’s Mechanical Turk in USA and Taskcn.com in China). Although the payment is relatively low, numerous people participate in the tasks in these online marketplaces. Drawing upon shopping value literature, we develop a research model by considering various value percep...
