Psychophysical Test

Psychophysical experiments conducted remotely over the internet permit data collection from large numbers of participants, but sacrifice control over sound presentation, and therefore are not widely employed in hearing research. To help standardize online sound presentation, we introduce a brief psychophysical test for determining if online experiment participants are wearing headphones. Listeners judge which of three pure tones is quietest, with one of the tones presented 180° out of phase across the stereo channels. This task is intended to be easy over headphones but difficult over loudspeakers due to phase-cancellation. We validated the test in the lab by testing listeners known to be wearing headphones or listening over loudspeakers. The screening test was effective and efficient, discriminating between the two modes of listening with a small number of trials. When run online, a bimodal distribution of scores was obtained, suggesting that some participants performed the task over loudspeakers despite instructions to use headphones. The ability to detect and screen out these participants mitigates concerns over sound quality for online experiments, a first step toward opening auditory perceptual research to the possibilities afforded by crowdsourcing.

AbstractThis paper describes a new initiative in support of the aim of Commission 46 of the IAU to develop and improve astronomy education at all levels throughout the world. This paper discusses the ideal specification of a facility to support basic astronomy within education programmes which are delivered to students who have access to the Internet. The available robotic telescopes are discussed against this specification and it is argued that the Bradford Robotic Telescope, uniquely, can support many thousands of users in the area of basic astronomy education, and the resource is free.Access to the Internet is growing in the developing world and this is true in education programmes. This paper discusses the serious problems of delivering to large numbers of students a web based astronomy education programme supported by a robotic telescope as part of a general education. It examines the problems of this form of teaching for teachers who have little experience of working with IT and little knowledge of basic astronomy and proposes how such teachers can be supported.The current system (http://www.telescope.org/) delivers astronomy education in the language, culture and traditions of England. The paper discusses the need to extend this to other languages, cultures and traditions, although for trainee teachers and undergraduates, it is argued that the current system provides a unique and valuable resource.

ABSTRACTThis article presents the methodology used in a population-based study of early communicative development in Norwegian children using an adaptation of the MacArthur-Bates communicative development inventories (CDI), comprising approximately 6500 children aged between 0 ; 8 and 3 ; 0. To our knowledge, this is the first CDI study collecting data via the Internet. After a short description of the procedures used in adapting the CDI to Norwegian and the selection of participants, we discuss the advantages and potential pitfalls of using web-based forms as a method of data collection. We found that use of web-based forms was far less time-consuming, and therefore also far less expensive than the traditional paper-based forms. The risk of coding errors was virtually eliminated with this method. We conclude that in a society with high access to the Internet, this is a method well worth pursuing.

Web-based data collection: an update Web-based data collection: an update Toon Taris, Paul Schreurs & Kees Jan Sepmeijer, Gedrag & Organisatie, Volume 18, June 2005, nr. 3, pp. 181-195 The rapid increase in the number of internet users has given web-based surveys the potential to become a powerful tool in survey research. The present study discusses the pros and cons of this technique for gathering data. Pros include speed, cost effectiveness and exclusion of interviewer and data entry errors; cons include low response rates, selective response, and possible problems with data quality. As an illustration we present the results of a study among well over 45,000 Dutch home care employees, showing that men, higher educated and younger employees were more likely to respond through the internet than others. Confirmatory factor analysis revealed that whereas the factor structures of selected work-related concepts were similar for respondents who used the internet vs. other respondents, their average scores differed strongly. Implications of these findings on data collection practices in social, work and organizational psychology are discussed.

a b s t r a c tof reference codes on a programming language and software evaluation. Today, most Source code library for the purposes of learning software developers in the form of documentation of the use of a programming language that can be accessed through the official website developer programming languages, forum and various blogs. Because of the complexity of the features most web-based Source code library can only be accessed through the website and some others have provided documentation on each software vendor from the developers company the device. This research tries to construct a model of the application Source code library that can be used as a form of documentation for learning the use of various programming languages flexibly both in online and offline. The application allows the renewal of data/content Source code library at a time when the Internet is still available or at the time of the user's area does not have a network the Internet. In the implementation of this research will be divided in three stages, namely data collection pre development, development and implementation, and data collection of post-war development. Data collection pre development intended to get a preliminary study about the provision the core issue at hand, while the development and implementation phase focuses on model software design into diagrams and make the programming code to implement the design that has been created. While the data collection stage of the post-war development was for revamping the application made in conclusion, withdrawal, and suggestions for further research topics.Keywords:Application, Source code library, software development a b s t r a kSource code library memungkinkan pengajar, programer maupun pelajar dan pengembang perangkat lunak untuk mendapatkan berbagai referensi kode-kode pada sebuah bahasa pemrograman perangkat lunak dan memberikan evaluasi. Saat ini, kebanyakan Source code library untuk keperluan pembelajaran pengembang perangkat lunak berupa dokumentasi penggunaan suatu bahasa pemrograman yang dapat diakses melalui website resmi pengembang bahasa pemrograman, forum dan berbagai blog. Karena kompleksitas fiturnya kebanyakan web-based Source code library hanya dapat diakses melalui website dan sebagian lainnya telah disediakan dokumentasi pada setiap software vendor dari perusahaan pengembang perangkat. Penelitian ini mencoba untuk membangun model aplikasi Source code library yang dapat digunakan sebagai bentuk dokumentasi pembelajaran penggunaan berbagai bahasa pemrograman secara fleksibel baik dalam kondisi online maupun offline. Aplikasi tersebut memungkinkan pembaharuan data/konten Source code library pada saat Internet masih tersedia atau pada saat pengguna pada area tidak memiliki jaringan Internet. Dalam pelaksanaannya penelitian ini akan dibagi dalam tiga tahapan, yaitu pengumpulan data pra pengembangan, pengembangan serta implementasi, dan pengumpulan data pasca pengembangan. Pengumpulan data pra pengembangan dimaksudkan untuk mendapatkan bekal studi pendahuluan tentang inti masalah yang sedang dihadapi, sedangkan tahap pengembangan dan implementasi berfokus pada memodelkan perancangan perangkat lunak ke dalam diagram dan membuat kode pemrograman untuk mengimplementasikan perancangan yang telah dibuat. Sedangkan tahapan pengumpulan data pasca pengembangan adalah untuk pembenahan aplikasi yang dibuat, penarikan kesimpulan, dan saran untuk topik penelitian selanjutnya.Kata Kunci:Aplikasi, Source code library, pengembangan perangkat lunak

Yamaha Vixion Club Bandung (YVCB) was formed on July 7, 2007 in the city of Bandung, as a place of friendship between Yamaha Vixion motorcyclists. In its organizational structure, YVCB has a Human Resource Development (HRD) division. Until now, there are more than 800 Yamaha Vixion Club Bandung members. This software is made to facilitate the work of the Yamaha Vixion Club Bandung HRD Division in processing member data. Created using Microsoft Webmatrix as an editor with the PHP programming language. The database uses MySQL with PHPMyAdmin as the software. The method used in making this software is prototyping so that between developers and customers can understand each other what the customer wants. The purpose of making web-based member data management software is that in terms of managing member data it can be done anytime and anywhere by just accessing the internet. In the use of the program, the author chose to use PHP, because PHP is the best and easiest to use in website programming language. Based on the last paragraph, the author intends to make aplication based computerized attendance so that become effective and efficient in terms of time.

The Web

In accordance with the technological advances of web-based information delivery via the internet has more value, because the information can be delivered easily, quickly,  spacious and interactive. Because this way, information is simply inserted into the web and within seconds the information can be accessed globally.  Submission of this information has not been used in Ngebruk Islamic Junior High School, Sumberpucung District, Malang Regency. Submission of the information in these schools still use manual way, such as by mail, bulletin boards, or orally. Surely this way less effective and efficient, since it requires a lot of expenses such as the purchase of paper, printing machine and maintenance, ink, and its scope was limited to the scope of the school.To reduce the above problems, the delivery of information in this school need to use web media created with the PHP programming language and MySQL. PHP is a programming language that is used to allow users to process information on the web, while MySQL is the software used to store the information on the web. Once the web is run online, the school entered information to the web, can be accessed via intenet by anyone without the limited space and time

As participant recruitment and data collection over the Internet have become more common, numerous observers have expressed concern regarding the validity of research conducted in this fashion. One growing method of conducting research over the Internet involves recruiting participants and administering questionnaires over Facebook, the world’s largest social networking service. If Facebook is to be considered a viable platform for social research, it is necessary to demonstrate that Facebook users are sufficiently heterogeneous and that research conducted through Facebook is likely to produce results that can be generalized to a larger population. The present study examines these questions by comparing demographic and personality data collected over Facebook with data collected through a standalone website, and data collected from college undergraduates at two universities. Results indicate that statistically significant differences exist between Facebook data and the comparison data-sets, but since 80% of analyses exhibited partial η2 < .05, such differences are small or practically nonsignificant in magnitude. We conclude that Facebook is a viable research platform, and that recruiting Facebook users for research purposes is a promising avenue that offers numerous advantages over traditional samples.
