Fresh and processed tomato (Lycopersicon esculentum) consumption has increased 40% in the United States over the last two decades. Through better breeding, fresh tomatoes now are marketed in different forms, sizes, colors, and flavors. However, little published information exists concerning consumer demand, preference, and demographic characteristics related to fresh tomato consumption. Taking advantage of a high percentage of Internet use in the U.S., two web-based surveys were released to approximately 6000 e-mail addresses reaching people in every region of the U.S. The surveys contained a total of 61 questions, including 50 digital images of five types of tomatoes (cherry, grape, cluster, plum, and regular slicing) with combinations of three additional factors (price, lycopene content, and production style) and demographic information. Among 389 respondents, 76% preferred and purchased slicing tomatoes in the 4 weeks prior to the survey. These were followed by grape/mini-pear (42%), plum (36%), cluster (27%), cherry (25%), and yellow slicing tomatoes (4.4%). Overall, production method (organic vs. conventional) had low relative importance in comparison to price and tomato type. However, younger participants (<age 38 years) placed more importance on production method. Participants between ages 39 and 57 years were the most price-sensitive, and female were less sensitive than males. Younger participants (<age 38 years) were less price-sensitive and placed more importance on the other attributes (production method, lycopene content, and tomato type).

Education over the Internet is going to be so big it is going to make e-mail usage look like a rounding error. John Chambers, Cisco Systems, New York Times, November 17, 1990 Web-based courses (Mesher, 1999) are defined as those where the entire course is taken on the Internet. In some courses, there may be an initial meeting for orientation. Proctored exams may also be given, either from the source of the Web-based course or off-site at a testing facility. The Internet-based course becomes a virtual classroom with a syllabus, course materials, chat space, discussion list, and e-mail services (Resmer, 1999). Navarro (2000) provides a further definition: a fully interactive, multimedia approach. Current figures indicate that 12% of Internet users in the United States use the Internet to take an online course for credit toward a degree of some kind (Horrigan, 2006). That number is indicative of the rapid proliferation of online courses over the past several years. The Web-enhanced course is a blend with the components of the traditional class while making some course materials available on a Web site, such as course syllabi, assignments, data files, and test reviews. Additional elements of a Web-enhanced course can include online testing, a course listserver, instructor-student e-mail, collaborative activities using RSS feeds and related technologies, and other activities on the Internet. One of the biggest concerns about Web-based courses is that users will become socially isolated. The Pew Internet and America Life Project found that online communities provide a vibrant social community (Horrigan, Rainie, & Fox, 2001). Clearly, students are not concerned or feel that other benefits outweigh the potential drawbacks. According to government research (Waits and Lewis, 2003), during the 2000-2001 academic year alone, an estimated 118,100 different credit courses were offered via distance education (with the bulk of that using Internet-based methods) by 2- and 4-year institutions in the United States. Over 3 million students were registered in these courses. Navarro (2000) suggests that faculty members are far more likely to start by incorporating Internet components into a traditional course rather than directly offering Web-based courses. These Web-enhanced courses might be considered the transition phase to the new paradigm of Internet-based courses. Rich learning environments are being created, with a shift from single tools to the use of multiple online tools, both to enhance traditional courses and to better facilitate online courses (Teles, 2002).

Tomatoes are one of the world's most consumed vegetable crops. In the United States, domestic production meets about 40% of the total domestic demand for fresh-market tomatoes, with the rest of the demand met by imports, mostly from Mexico and Canada. Since 2000, however, fresh tomato production in the United States has exhibited a steady declining trend. One major reason is the increased competition from Mexico. This 4-page fact sheet written by Zhengfei guan, Trina Biswas, and Feng Wu and published by the UF/IFAS Food and Resource Economics Department argues for US government measures to help the domestic tomato industry resolve labor shortages and encourage research and development of labor-saving technologies such as mechanical harvesting to make the US tomato industry more competitive and sustainable. http://edis.ifas.ufl.edu/fe1027

ABSTRACT In March 2000, instructors from the Marine Safety Port Operations School at the U.S. Coast Guard Training Center Yorktown in Yorktown, Virginia delivered Incident Command System (ICS) 200-level training over the World Wide Web. The ICS Web-based training was part of an ensemble of courses that were offered over the Web to evaluate a software package developed by an independent contractor and to measure the effectiveness of Web-based training in the U.S. Coast Guard. Students throughout the United States, including Alaska, participated in the training using their personal or work computers. A number of students successfully met the objectives of the ICS 200 training without leaving their locale. To evaluate the efficacy of delivery, students were given pretests and posttests to measure their knowledge of ICS both before and after the training. The course consisted of two 4-hour Web-based delivery sessions using the National Interagency Incident Management System (NIIMS) curriculum for ICS 200. The U.S. Coast Guard adopted NIIMS ICS as the standardized response management system for all Coast Guard response operations and faces the task of providing the appropriate ICS training to all its members. Currently, Coast Guard ICS training is being provided at resident courses within the Coast Guard Marine Safety Schools and by field instructors. The advantages, foibles, and lessons learned from this Web-based training experiment as well as the future of using the Internet for delivery of ICS courses are discussed.

A Review of: Scarletto, E. A., Burhanna, K. J., & Richardson, E. (2013). Wide awake at 4 AM: A study of late night user behavior, perceptions and performance at an academic library. Journal of Academic Librarianship, 39(5), 371-377. http://dx.doi.org/10.1016/j.acalib.2013.02.006 Abstract Objective – To assess late night library usage, including a demographic profile of students benefitting from late night hours, with an analysis of the services and resources they used, and whether the use of late hours is connected to student success. Design – A mixed-methods approach including quantitative demographic information alongside qualitative user feedback collected using a web-based survey. Setting – A large, public research university library in the United States of America using late night operating hours (11 P.M. to 7:30 A.M.) to create 24-hour library availability 5 days per week. Subjects – Undergraduate and graduate students. Methods – Using the university’s building monitoring database (BMD), researchers collected data on which students were using the library building when late night hours were in effect for fall and spring semesters. Along with the date and time of entry, the BMD collected the university ID number of the students and their email address. Using student ID numbers, information from the BMD was cross-referenced with anonymized demographic information from the university’s institutional planning office, enabling comparisons across a range of other data, including students’ discipline, GPA, and other information. Researchers emailed students the web-based survey, directly targeting users who had made use of the library’s late night operating hours. Survey questions investigated when students used the library, explored student aims when in the library, and asked students to rank the tasks they were trying to accomplish while in the library. In addition, researchers sought student feedback on what services and resources they used during late hours, asking students to identify services and resources they would have liked to use but which were not offered during late night hours, and inquiring about students’ sense of safety and security when using the library late at night. Main Results – In total, researchers report that 5,822 students, representing approximately 21% of the campus population, visited the library during the late hours, for 22,383 visits. Researchers report that 57% of late night users took advantage of the extended hours on more than one occasion, with 39% returning three or more times. Sundays were the most popular day, while Thursdays were least popular. Researchers also tracked entry times, with the most popular entry times occurring between 11 P.M. to 2 A.M., accounting for 80% of all late night visits. While survey respondents were drawn entirely from the late night users, 63% preferred using the library late at night versus standard daytime operating hours. The overall survey response rate was less than 5%. Survey respondents (n=243) reported participating in a variety of activities while visiting during late night library hours, with quiet study (87%), working on projects or papers (72%), and group study (42%) as the most frequently reported activities. Respondents also ranked the top three activities they hoped to accomplish while in the library: quiet study (50%) and work on projects and papers (34%) remained top activities, though group study (20%) fell to fourth place, slightly behind the third-ranked activity of printing or copying documents (22%). Respondents reported their use of services during late night hours, indicating use of the university’s wireless Internet access, library printers, computers, and online databases and electronic resources. The only staff service point available to students during overnight hours, circulation services, was used by 16% of respondents. Regarding student responses about what services were not offered that they would have liked to have available, the researchers reveal that “[f]ood and drink were overwhelmingly the most frequently requested services” (p. 374), followed by a desire for more comfortable furniture and spaces. Some respondents also requested that late night hours be extended to seven days a week. Overall, 96% of those submitting user feedback reported a sense of security, an important consideration for late night hours. Regarding the sample, researchers found that the population of late night library users closely reflected the overall university population. An independent samples t-test comparing the differences between the average GPA of late night users to the average GPA of the overall university population was statistically insignificant. For undergraduates only, there exists a small difference between the retention rate of students using late night hours (84.6%) versus overall university retention rate (80.2%). A Pearson’s chi-squared test revealed a statistically significant association between late night library use and retention rates for both undergraduate and graduate populations when compared to the retention rates of non-late night users across the same student groups. Conclusion – This study reveals that undergraduate students in particular make use of late night hours for studying or other academic activities, and positions the late night model as a successful customer service offering at Kent State University. Although researchers do conclusively connect the availability of late night hours to student retention and academic success, their study points to the need for further research exploring this question.

The use of distance learning in higher education is not a new concept (Worlock, 1987). Old-fashioned correspondence courses served this purpose for many years, appealing to those who could not attend classes in an institutional setting. Radio learning programs have beamed lessons on mathematics, science and other subjects around the world. The Internet has brought a new dimension to this concept: distance learning now means the opportunity to mirror rather than merely supplement classroom experience (Taub, 1997). Distance learning options encompass a range of delivery options, both synchronous and asynchronous. The synchronous approach can include real-time interaction between course faculty and students, while asynchronous approaches rely more on downloading course slides, audio and video from a Web site, which may be supplemented by e-mail contact (Clark, 1999). In the current environment, it is increasingly common to find courses that mix synchronous and asynchronous modes of delivery. The virtual classroom can include real-time Web-based videoconferencing with teachers and students, Web pages with course slides and content to be reviewed by the user, and the more traditional e-mail and telephone exchanges (Clark, 1999). In addition, the synchronous modes such as videoconferencing are frequently backed up in an asynchronous format, usually as transcripts capable of being accessed by the user after the session has concluded. Along with modes of delivery, the expectations for Web-based learning have grown as well, with today’s users becoming ever more sophisticated. In the U.S. and around the world, individuals and corporations are increasing their spending on high-technology education (Clark, 1999) through a variety of institutions such as traditional universities, specialized institutes, in-house training divisions, and Web-based virtual education programs. The Johns Hopkins School of Hygiene and Public Health is an acknowledged leader in the teaching and practice of public health. In 1996, the School began exploring ways to reach beyond the walls of the traditional classroom to provide public health education through the technology now widely accessible. As a result of a competitive proposal submitted to the U.S. Centers for Disease Control, the School of Public Health was one of four schools selected with the purpose of developing a distance-education curriculum, to upgrade the knowledge and skills of mid-career public health staff of that agency. The overall curriculum was designed to lead to a Graduate Certificate in Public Health. This certificate also met approximately one-half of the core requirements for the MPH degree, the most frequently awarded degree in the school.

Within the last decade, the Internet has become one of the fastest growing technologies. According to research conducted by the Pew Internet and American Life Project, nearly 60% of the United States (U.S.) population is now online, with variation based on race, age, education, region and income (Spooner, 2003). Despite the persistent discrepancies in access, Internet usage among the U.S. population is steadily increasing, up by 9% since 2000. Throughout the 1990s, well-educated white men primarily populated the Internet; however, this situation has changed in the last 5 years. As of 2000, women made up 50% of Internet users and “Hispanics [were] just as likely to be online as whites, and African Americans are coming online at accelerating rates” (Horrigan, 2000, p. 2). Overall, the Pew study found that activities such as e-mail (and other online communication forums); online shopping; Web surfing; connectivity with family and friends; hobbies; news; and information are popular online uses. Through the Pew Institute’s many studies, it is clear the Internet is a key aspect of social life in U.S. culture.

e14668 Background: 5FU + leucovorin (LV) containing regimens are the most commonly used regimens for colorectal cancer (CRC). A LV shortage in the U.S. beginning Apr 2010 became critical by fall 2011. In May ’11, levoleucovorin (LLV) was approved to treat CRC in the U.S. LV replacement by LLV incurs a 34 fold cost increase. This study examines if the LV shortage impacted colon cancer (CC) regimen selection and LV/LLV usage in the adjuvant and 1st line tx. Methods: Data obtained via web-based, drug dispensing technology was used to identify 3 groups of adult CC patients starting adjuvant or first-line tx within a 6 month period: Group 1 (Q2,Q3 2009), Group 2 (Q2,Q3 2010) and Group 3 (Q4, 2011 – Q1, 2012). Regimen selection and LV usage were examined from tx onset through completion. Results: Adjuvant and first-line tx administered by 545 practices across 47 states was examined and including 2,502 pts, 2,551 pts, and 2,689 pts in Groups 1, 2, and 3 respectively. The median pt age was 66. 77% of pts in each group received FOLFOX for adjuvant tx. Approx 7% of pts in Groups 1 and 2 received capecitabine-containing regimens compared to 9.9% in Group 3. 58% of pts in Group 1, 51% in Group 2 and 56% in Group 3 received mFOLFOX6 or mFOLFIRI + bevacizumab for first-line tx. Use of 5FU + LV or LLV-containing regimens remained constant in all 3 groups. The Table summarizes LV/LLV usage in LV-containing regimens planned for ’09 - Q1 of ‘12. Lower LV dosing and relative dose intensity (RDI), fewer LV administrations and increased LLV usage are seen for the time period reviewed. Conclusions: Based on data examined from 2009-Q1 2012, while no significant impact on regimen selection was observed, the LV shortage significantly decreased LV and raised LLV usage (and cost) in the adjuvant and first-line tx for colon cancer.

An American Language is a political history of the Spanish language in the United States. The nation has always been multilingual and the Spanish language in particular has remained as an important political issue into the present. After the U.S.-Mexican War, the Spanish language became a language of politics as Spanish speakers in the U.S. Southwest used it to build territorial and state governments. In the twentieth century, Spanish became a political language where speakers and those opposed to its use clashed over what Spanish's presence in the United States meant. This book recovers this story by using evidence that includes Spanish language newspapers, letters, state and territorial session laws, and federal archives to profile the struggle and resilience of Spanish speakers who advocated for their language rights as U.S. citizens. Comparing Spanish as a language of politics and as a political language across the Southwest and noncontiguous territories provides an opportunity to measure shifts in allegiance to the nation and exposes differing forms of nationalism. Language concessions and continued use of Spanish is a measure of power. Official language recognition by federal or state officials validates Spanish speakers' claims to US citizenship. The long history of policies relating to language in the United States provides a way to measure how U.S. visions of itself have shifted due to continuous migration from Latin America. Spanish-speaking U.S. citizens are crucial arbiters of Spanish language politics and their successes have broader implications on national policy and our understanding of Americans.
