Selected AbstractsSEARCHING FOR EXPLANATORY WEB PAGES USING AUTOMATIC QUERY EXPANSIONCOMPUTATIONAL INTELLIGENCE, Issue 1 2007Manabu Tauchi When one tries to use the Web as a dictionary or encyclopedia, entering some single term into a search engine, the highly ranked pages in the result can include irrelevant or useless sites. The problem is that single-term queries, if taken literally, underspecify the type of page the user wants. For such problems automatic query expansion, also known as pseudo-feedback, is often effective. In this method the top n documents returned by an initial retrieval are used to provide terms for a second retrieval. This paper contributes, first, new normalization techniques for query expansion, and second, a new way of computing the similarity between an expanded query and a document, the "local relevance density" metric, which complements the standard vector product metric. Both of these techniques are shown to be useful for single-term queries, in Japanese, in experiments done over the World Wide Web in early 2001. [source] Environment for engineering design, analysis, and simulation for education using MATLAB via the World Wide Web.COMPUTER APPLICATIONS IN ENGINEERING EDUCATION, Issue 3 2002Abstract In Part II of this paper, we present representative examples that demonstrate the capabilities and features of the developed education environment that allows one to simulate in real time engineering systems utilizing the power of MATLAB through a web browser interface. The web-based graphical user interface (GUI) provides the means for the user to input system parameters and the display of the analysis results. The examples presented demonstrate the required clarity of the developed GUI, and the nature and type of the results returned to the web browser of the user in real time. This environment has the capability to return to the user textual, graphical, pictorial, and animation related material. The user has the option to download analysis results in any of the generated forms to the client computer. This work demonstrates the ease of implementation and advantages of using this technology to aid in classroom instruction. Users with Internet can access the developed simulation modules at http://zodhia.uta.edu/development. © 2002 Wiley Periodicals, Inc.

Burbules This article offers an exploration of the idea, and the experience, of aporia (usually translated as ,doubt') in Plato's dialogue, the Meno, and in other teaching/learning contexts. A metaphor that moves throughout the article is the experience of being lost when exploring the World Wide Web and other weblike or hypertextual environments. The article represents the experience of movement, following uncertain connections, and cycling back through certain points by way of the form in which it is written. Through a series of interlinked passages, the article explores the ideas of webs, passages, and paths of connection as models of discovery, getting lost, making unexpected connections, and learning. It explores different types of aporia and shows how aporia can be seen, not as a barrier to knowledge, or as simply ,clearing the ground' for new learning, but as an integral dimension of learning (and of teaching) itself. By design, it offers not an argument but a way of exploring complex ideas; in a different medium, it could have been produced as a hypertextual article itself (and in this way might also spark reflection on the possibilities and limits of hypertextual writing within a print medium). [source] A systematic review of the diagnostic classifications of traumatic dental injuriesDENTAL TRAUMATOLOGY, Issue 2 2006Karla Maria Pugliesi da Costa Feliciano Abstract,,, A systematic review of the literature was undertaken to evaluate the criteria used for the diagnostic classification of traumatic dental injuries from an epidemiological standpoint. The methodology used was that suggested by the Cochrane Collaboration and the National Health Service. A total of 12 electronic bibliographical databases (BBO, BioMed Central, Blackwell Synergy, Cochrane, DARE, EMBASE, HighWire, LILACS, MEDLINE, PubMed Central, SciELO, SciSearch) and the World Wide Web were searched. There was no attempt to specify the strategy in relation to date, study design, or language. The last search was performed in May 2003. Two reviewers screened each record independently for eligibility by examining titles, abstracts, keywords and using a standardized reference form. Disagreements were resolved through consensus. The final study collection consisted of 164 articles, from 1936 to 2003, and the population sample ranged from 38 to 210 500 patients. 54 distinct classification systems were identified. According to the literature, the most frequently used classification system was that of Andreasen (32%); as regards the type of injury, the uncomplicated crown fracture was the most mentioned lesion (88.5%). Evidence supports the fact that there is no suitable system for establishing the diagnosis of the studied injuries that could be applied to epidemiological surveys. [source] Legibility evaluation using point-of-regard measurementELECTRICAL ENGINEERING IN JAPAN, Issue 4 2008Daisuke Saito Abstract Web site visibility has become important because of the rapid dissemination of the World Wide Web, and combinations of foreground and background colors are crucial in providing high visibility. In our previous studies, the visibilities of several web-safe color combinations were examined using a psychological method. In those studies, simple stimuli were used because of experimental restriction. In this paper, legibility of sentences on web sites was examined using a psychophysiological method, point-of-regard measurement, to obtain other practical data. Ten people with normal color sensations ranging from ages 21 to 29 were recruited. The number of characters per line in each page was arranged in the same number, and the four representative achromatic web-safe colors, that is, #000000, #666666, #999999, and #CCCCCC, were examined. The reading time per character and the gaze time per line were obtained from point-of-regard measurement, and the normalized with the reading time and the gaze time of the three colors were calculated and compared. It was found that the time of reading and gaze become long at the same ratio when the contrast decreases by point-of-regard measurement. Therefore, it was indicated that the legibility of color combinations could be estimated by point-of-regard measurement. © 2007 Wiley Periodicals, Inc.

In our previous studies, the visibilities of several web-safe color combinations were examined using a psychological method. In those studies, simple stimuli were used because of experimental restrictions. In this study, the legibility of sentences on Web sites was examined using an oculomotor-based psychophysiological method, and the effect of achromatic color combinations, that is, the contrast, was examined in terms of the calculated reading time. The presentation stimuli were positive colorations, whose font color luminance was lower than the background color, and negative colorations, whose font color luminance was higher than the background color. The number of characters per line was arranged to be the same on each page, and four levels of achromatic contrast (the contrast between the background color and the font color), namely, 92.5%, 75.0%, 50.0%, and 25.0%, were examined. It was shown that the reading time increased when the contrast decreased. However, with negative coloration, there were great differences between individuals. Therefore, considering web accessibility, legibility is found to be improved when using a positive coloration. © 2010 Wiley Periodicals, Inc.

Eynon The rapid growth of Internet for the delivery of information has enabled teaching materials to be placed on websites allowing student access to course material. It is the aim of this paper to evaluate a cohort of dental undergraduate students who have used Web-based courseware in prosthetic dentistry for a semester. A questionnaire was distributed to clinical undergraduate students prior to the use of the prosthetics course to determine their experience of using the World Wide Web (WWW) and their expectations of an online course. A second questionnaire was distributed at the end of 6 months which asked about their usage and opinions of the prosthetics Web-based courseware. The main concerns raised at the beginning of the course were related to computer access, the ability to use computers, the time involved and their conception that the e-course would be an additional burden. The main potential benefits were perceived to be convenience, availability of information and the ability to reinforce or catch up on aspects of the module they did not understand or had missed. Feedback at the end of the year showed that most students had accessed the Web-based courseware site at least once a month and, generally, their comments were favourable, dispelling some of the initial perceived fears. They felt that the website was a quick and convenient way to access information and was a good additional resource. Access to the site and printing information were the main problems raised by the students who had to use a shared cluster. In conclusion, Web-based courseware was felt to be a useful additional resource for students. However, this research showed that sufficient computers and printers must be available for such a resource to become an integrated part of the dental course. [source] Teaching oral surgery to undergraduate students: a pilot study using a Web-based practical courseEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 3 2003Luciana Corrêa The Internet has been used in oral surgery teaching mainly to deliver learning material across the World Wide Web and to make use of online interactivity resources in everyday surgical practice, such as by e-mails, discussion groups, and chats. The aim of this paper is to describe and evaluate a Web-based practical course on oral surgery principles, which was applied to undergraduate students. This course was investigated as a distance learning simulation in which the student would be performing surgical activities at home, and the teacher and the school environment would be absent. A Web site was created containing the course material. For this study, the students participated in the Web-based course in a multimedia lab equipped with computers and Internet, internal sound system and TV circuits. In the event of significant mistakes by students, the TV circuit could be used to show the correct procedure for all the participants at the same time. Microcameras were used to monitor the student's actions during the Internet use. Students' impressions were determined by a questionnaire. Computer manipulation with ease and antiergonomic postures were observed. We concluded that distance learning courses with practical modules must be considered as a special type of educational modality, with reference to the relationship between the student and the computer. [source] A metagenetic algorithm for information filtering and collection from the World Wide WebEXPERT SYSTEMS, Issue 2 2001Z.N. Zacharis This paper describes the implementation of evolutionary techniques for information filtering and collection from the World Wide Web. We consider the problem of building intelligent agents to facilitate a person's search for information on the Web. An intelligent agent has been developed that uses a metagenetic algorithm in order to collect and recommend Web pages that will be interesting to the user. The user's feedback on the agent's recommendations drives the learning process to adapt the user's profile with his/her interests. The software agent utilizes the metagenetic algorithm to explore the search space of user interests. Experimental results are presented in order to demonstrate the suitability of the metagenetic algorithm's approach on the Web. [source] Annotated chromosome maps for renal disease,HUMAN MUTATION, Issue 3 2009Amy Jayne McKnight Abstract A combination of linkage analyses and association studies are currently employed to promote the identification of genetic factors contributing to inherited renal disease. We have standardized and merged complex genetic data from disparate sources, creating unique chromosomal maps to enhance genetic epidemiological investigations. This database and novel renal maps effectively summarize genomic regions of suggested linkage, association, or chromosomal abnormalities implicated in renal disease. Chromosomal regions associated with potential intermediate clinical phenotypes have been integrated, adding support for particular genomic intervals. More than 500 reports from medical databases, published scientific literature, and the World Wide Web were interrogated for relevant renal-related information. Chromosomal regions highlighted for prioritized investigation of renal complications include 3q13,26, 6q22,27, 10p11,15, 16p11,13, and 18q22. Combined genetic and physical maps are effective tools to organize genetic data for complex diseases. These renal chromosome maps provide insights into renal phenotype-genotype relationships and act as a template for future genetic investigations into complex renal diseases. New data from individual researchers and/or future publications can be readily incorporated to this resource via a user-friendly web-form accessed from the website: www.qub.ac.uk/neph-res/CORGI/index.php.

[source] VSD: A database for schizophrenia candidate genes focusing on variations,HUMAN MUTATION, Issue 1 2004Min Zhou Abstract Schizophrenia is a common mental disease characterized by delusions, hallucinations, and formal thought disorder. It has been demonstrated with genetic evidence that the disease is a polygenic disorder. Pharmacological, neurochemical, and clinical studies have suggested a number of schizophrenia susceptibility loci. In order to systematically search for genes with small effect in the development of schizophrenia, a database called VSD was established to provide variation data for publicly available candidate genes. Most of the genes encode neurotransmitter receptors, neurotransmitter transporters, and the enzymes involved in their metabolism. Other candidate genes extracted from published literature are also included. The variation information has been collected from publicly available mutation and polymorphism databases such as dbSNP, HGVbase, and OMIM, with single nucleotide polymorphism (SNP) being the most abundant form of collected variations. Reference sequences from NCBI's RefSeq database are used as references when positioning variation at transcript and protein levels. The nonsynonymous SNPs (nsSNPs) that lead to amino acid changes in the functional sites or domains of proteins are distinguished since they are more likely to affect protein function and would be target SNPs for association studies. In addition to variation data, gene descriptions, enzyme information, and other biological information for each gene locus are also included. The latest version of VSD contains 23,648 variations assigned to a total of 186 genes. Five-hundred eighty-eight domains and sites annotated in the SWISS-PROT and InterPro databases are found to contain nsSNPs. VSD may be accessed via the World Wide Web (www.chgb.org.cn/vsd.htm) and will be developed as an up-to-date and comprehensive locus-specific resource for identifying susceptibility genes for schizophrenia.

Mantzaridis Abstract The definition of quality in a ,life' environment, such as that of the World Wide Web has proven to have many, often conflicting interpretations. Factors such as the point of view, the expertise and type of usage of the critic can influence dramatically such a definition and its results. Thus, the key point is to distance oneself from single perspectives and obtain a complete picture of the system as a single entity working towards a specific goal. This paper is an attempt at creating a general model of quality procedures. It will concentrate mainly in customer service, system viability and quality of offering evaluation. Some of the material mentioned is based on adapted classical models that can be used equally to apply and observe standards of offerings in the wider WEB community.

[source] Using the moving average rule in a dynamic web recommendation systemINTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 6 2007Yi-Jen Su In this, the Information Age, most people are accustomed to gleaning information from the World Wide Web. To survive and prosper, a Web site has to constantly enliven its content while providing various and extensive information services to attract users. The Web Recommendation System, a personalized information filter, prompts users to visit a Web site and browse at a deeper level. In general, most of the recommendation systems use large browsing logs to identify and predict users' surfing habits. The process of pattern discovery is time-consuming, and the result is static. Such systems do not satisfy the end users' goal-oriented and dynamic demands. Accordingly, a pressing need for an adaptive recommendation system comes into play. This article proposes a novel Web recommendation system framework, based on the Moving Average Rule, which can respond to new navigation trends and dynamically adapts recommendations for users with suitable suggestions through hyperlinks. The framework provides Web site administrators with various methods to generate recommendations. It also responds to new Web trends, including Web pages that have been updated but have not yet been integrated into regular browsing patterns. Ultimately, this research enables Web sites with dynamic intelligence to effectively tailor users' needs. © 2007 Wiley Periodicals, Inc. Int J Int Syst 22: 621,639, 2007.

Proffen Computer simulations are a versatile tool to enhance the teaching of diffraction physics and related crystallographic topics to students of chemistry, materials science, physics and crystallography. Interactive computer simulations are presented, which have been added to a World Wide Web (WWW) based tutorial. A simple WWW interface is used to choose appropriate values for selected simulation parameters. The resulting structure and diffraction pattern are then plotted on the screen. Simulated structures range from a single atom to complex disordered or modulated structures. The simple interface requires no special computing knowledge and allows students to explore systematically the relationship between a real-space structure and the corresponding diffraction pattern. The large function set of the underlying simulation program (DISCUS) makes it easy to tailor the tutorial to a given syllabus by modifying or extending the current interactive examples. [source] A systematic review of interrater reliability of pressure ulcer classification systemsJOURNAL OF CLINICAL NURSING, Issue 3 2009Jan Kottner Aims., To review systematically the interrater reliability of pressure ulcer classification systems to find out which classification should be used in daily practice. Background., Pressure ulcer classification systems are important tools in research and practice. They aim at providing accurate and precise communication, documentation and treatment decisions. Pressure ulcer classifications are criticised for their low degree of interrater reliability. Design., Systematic review. Methods., The data bases MEDLINE, EMBASE, CINAHL and the World Wide Web were searched. Original research studies estimating interrater reliability of pressure ulcer classification systems were included. Study selection, data extraction and quality assessment was conducted independently by two reviewers. Results., Twenty-four out of 339 potentially relevant studies were included in the final data synthesis. Due to the heterogeneity of the studies a meaningful comparison was impossible. Conclusions., There is at present not enough evidence to recommend a specific pressure ulcer classification system for use in daily practice. Interrater reliability studies are required, in which comparable raters apply different pressure ulcer classification systems to comparable samples. Relevance to clinical practice., It is necessary to determine the interrater reliability of pressure ulcer classifications among all users in clinical practice. If interrater reliability is low the use of those systems is questionable. On the basis of this review there are no recommendations as to which system is to be given preference. [source] A multimedia-enhanced collaborative learning environmentJOURNAL OF COMPUTER ASSISTED LEARNING, Issue 1 2000C-K. Looi Abstract The proliferation of the Internet has brought about the notion of online virtual communities. One enabling technology for online communities is multiuser environments such as Multi-User Dimensions (MUDs) and Object-Oriented MUDS (MOOs). These text-based collaborative learning environments have recently have been integrated with the World Wide Web, thus harnessing the graphics and multimedia-rich environments available therein. Learners can directly experience, manipulate, and create objects in their rich multimedia form. MUDs and MOOs are augmented with synchronous collaboration technology that provided simultaneous control and viewing of shared documents and applications. In this paper, we describe a multimedia-enhanced MOO system called SpaceALIVE! and our experiences from a pilot project involving Singapore students who use SpaceALIVE! as a collaborative learning environment are reported. [source] Gender and Turn Allocation in a Thai Chat RoomJOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 1 2003Siriporn Panyametheekul This paper analyzes gender in relation to turn allocation in a popular Thai chat room on the World Wide Web. We analyze turn-taking and response patterns in light of Sacks, Schegloff and Jefferson's (1974) model of turn allocation in face-to-face conversation, taking into consideration the independent variable of participant gender. We also analyze use of, and responses to, flirtation in the chat room. Our results show that females participate more often and receive a higher rate of response from both females and males. Males, who are in the minority, must work harder to take the floor, even in their attempted flirtatious interactions. These results suggest that gender interacts with culture online in complex ways: Contrary to previous findings on gender in chat rooms, and contrary to culturally-based expectations about the subordinate status of Thai women, females appear to be relatively empowered in the Thai chat room studied here, as assessed through turn allocation patterns. [source] Hyperlink Analyses of the World Wide Web: A ReviewJOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 4 2003Han Woo Park We have recently witnessed the growth of hyperlink studies in the field of Internet research. Although investigations have been conducted across many disciplines and topics, their approaches can be largely divided into hyperlink network analysis (HNA) and Webometrics. This article is an extensive review of the two analytical methods, and a reflection on their application. HNA casts hyperlinks between Web sites (or Web pages) as social and communicational ties, applying standard techniques from Social Networks Analysis to this new data source. Webometrics has tended to apply much simpler techniques combined with a more in-depth investigation into the validity of hypotheses about possible interpretations of the results. We conclude that hyperlinks are a highly promising but problematic new source of data that can be mined for previously hidden patterns of information, although much care must be taken in the collection of raw data and in the interpretation of the results. In particular, link creation is an unregulated phenomenon and so it would not be sensible to assume that the meaning of hyperlinks in any given context is evident, without a systematic study of the context of link creation, and of the relationship between link counts, among other measurements. Social Networks Analysis tools and techniques form an excellent resource for hyperlink analysis, but should only be used in conjunction with improved techniques for data collection, validation and interpretation. [source] A Web-Based Interactive Database System for a Transcranial Doppler Ultrasound LaboratoryJOURNAL OF NEUROIMAGING, Issue 1 2006Mark J. Gorman MD ABSTRACT Background. Variations in transcranial Doppler (TCD) examination performance techniques and interpretive paradigms between individual laboratories are a common challenge in the practice of TCD. Demand for rapid access to patient ultrasound examination data and report for use in intensive care settings has necessitated a more flexible approach to data management. Both of these issues may benefit from a computerized approach. Methods. We describe the application of a World Wide Web-based database system for use in an ultrasound laboratory. Results. Databasing information while generating a TCD report is efficient. Web accessibility allows rapid and flexible communication of time-sensitive report information and interpretation for more expeditious clinical decision making. Conclusions. Web-based applications can extend the reach and efficiency of traditionally structured medical laboratories.

The goal of Web 2.0 is to work with the World Wide Web rather than against it. That is, it should design services and applications that harness the inherent strengths of the Web rather than create services that view the Web only as an afterthought rather than as a strategic piece of the overall enterprise. This article contrasts Web 1.0 and Web 2.0 and discusses ways that psychologists can harness Web 2.0 trends like crowdsourcing, user-generated content, and social networking. [source] Learning at the nanoscale: The impact of students' use of remote microscopy on concepts of viruses, scale, and microscopyJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 3 2003M. Gail Jones The rapid pace of development is bringing advanced technologies to the World Wide Web (WWW), and, as a result, schools have access to new tools for science investigations. In this exploratory study, we investigated how an educational experience organized around students' use of a WWW-controllable atomic force microscope (AFM) influenced students' understandings of viruses. The context for the study was a weeklong unit on viruses for two high school biology classes which incorporated student use of the WWW controllable AFM. We also investigated how the haptic (involving kinesthetics and touch) experiences afforded by this tool might influence students' knowledge of viruses, microscopy, and nanometer scale. Fifty students from two high school biology classes participated in a series of instructional activities and pre- and postassessments (knowledge test, opinion questionnaire, and interviews). Results showed that students' understandings of microscale, virus morphology, and dimensionality changed as a result of the experiences. Students' conceptions moved from a two-dimensional textbook-like image of a virus to a three-dimensional image of an adenovirus. The results of this preliminary study suggest that the use of the technology as a tool for learning about morphology of materials too small to see may be beneficial. © 2003 Wiley Periodicals, Inc.

Hoffman Early research on using the World Wide Web indicated that middle school students did not explore much and used Web tools naively. In response to these challenges, an on-line research engine, Artemis, was designed to provide a permanent workspace and allow students access to preselective on-line resources. This study investigated the depth and accuracy of sixth-grade students' content understandings as well as their use of search and assess strategies when they used on-line resources via Artemis. Eight student pairs from two science classes experienced support from teachers and used scaffolded curriculum materials while completing four on-line inquiry units during 9 months. Multiple sources of data were collected, including video recordings of students' computer activities and conversations, students' artifacts and on-line postings, classroom and lab video recordings, and interview transcripts. Analyses of data showed that students constructed meaningful understandings through on-line inquiry, although the accuracy and depth of their understandings varied. The findings suggest that students might develop accurate and in-depth understandings if they use search and assess strategies appropriately, if resources are thoughtfully chosen, and if support from the learning environment is extensively provided. This research lends evidence to questions regarding the value of students engaging in on-line inquiry. © 2003 Wiley Periodicals, Inc.

It provides strategies and resources that may offer guidance to NPs who are attempting to balance the continued independence of patients with dementia, as represented by driving, with the safety not only of such patients but also of the public at large. Data sources A review of the biomedical literature, resources available on the World Wide Web, and illustrative case studies were used. Conclusions The diagnosis of dementia alone is often insufficient to determine driver competence because the topographic losses of dementia are complex. Recognizing when cessation should occur is made more difficult because objective assessment tools do not exist to predict impaired driving skills. Recommending driving cessation at the appropriate time can be a challenge for NPs, who must balance such a significant impact on the driver's autonomy with concerns about public safety if the patient continues to drive despite progressive impairment. Implications for practice The progressive loss of cognitive abilities in dementia presents a series of ongoing challenges for the patient throughout the disease continuum. Unfortunately, the recommendation to stop driving can present one of the more immediate issues confronting the patient, the family, and the healthcare provider. Failure to assess diminished driving skill can lead either to premature or to delayed driving cessation. Either outcome can have adverse effects on the patient, the patient's family, and public safety.

[source] Perspectives on social taggingJOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 12 2009Ying Ding Social tagging is one of the major phenomena transforming the World Wide Web from a static platform into an actively shared information space. This paper addresses various aspects of social tagging, including different views on the nature of social tagging, how to make use of social tags, and how to bridge social tagging with other Web functionalities; it discusses the use of facets to facilitate browsing and searching of tagging data; and it presents an analogy between bibliometrics and tagometrics, arguing that established bibliometric methodologies can be applied to analyze tagging behavior on the Web. Based on the Upper Tag Ontology (UTO), a Web crawler was built to harvest tag data from Delicious, Flickr, and YouTube in September 2007. In total, 1.8 million objects, including bookmarks, photos, and videos, 3.1 million taggers, and 12.1 million tags were collected and analyzed. Some tagging patterns and variations are identified and discussed. [source] A method for measuring the evolution of a topic on the Web: The case of "informetrics"JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 9 2009Judit Bar-Ilan The universe of information has been enriched by the creation of the World Wide Web, which has become an indispensible source for research. Since this source is growing at an enormous speed, an in-depth look of its performance to create a method for its evaluation has become necessary; however, growth is not the only process that influences the evolution of the Web. During their lifetime, Web pages may change their content and links to/from other Web pages, be duplicated or moved to a different URL, be removed from the Web either temporarily or permanently, and be temporarily inaccessible due to server and/or communication failures. To obtain a better understanding of these processes, we developed a method for tracking topics on the Web for long periods of time, without the need to employ a crawler and relying only on publicly available resources. The multiple data-collection methods used allow us to discover new pages related to the topic, to identify changes to existing pages, and to detect previously existing pages that have been removed or whose content is not relevant anymore to the specified topic. The method is demonstrated through monitoring Web pages that contain the term "informetrics" for a period of 8 years. The data-collection method also allowed us to analyze the dynamic changes in search engine coverage, illustrated here on Google,the search engine used for the longest period of time for data collection in this project.
