Hope communication as a predictor of documented and undocumented Latina/o high school students’ college intentions across an academic year

Drawing from hope theory, we examined whether hope communication predicted undocumented and documented U.S. Latina/o youth’s college intentions across an academic year. With three waves of survey data from 172 documented and 253 undocumented Latina/o high school students, auto-regressive cross-lagged analyses revealed that parent, teacher, and friend hope communication at the beginning of the year indirectly increased students’ college intentions by the end of the year. A trend emerged whereby undocumented students reported significantly less hope communication and weaker college intentions than documented students within most of the waves. Our findings suggest that hope communication has the potential to increase the educational, economic, and social mobility of Latina/o immigrant students by increasing their intentions to attend college.     

Third‐person perception and school violence

The study is the first of its kind to study third‐person perception within the context of school violence. Linkages to the health psychology literature (optimistic bias) provide the basis for further understanding of adolescents’ perceptions of school violence and the influence of media violence in their lives. Results from a survey of 1,500 middle school and high school students suggest third‐person perception regarding media violence decreases with age, and is influenced by perceived reality of media violence, optimistic bias, and knowledge of real world youth violence.

Children’s and school libraries in the USSR

Abstract

Changes in the state structure since 1989 and their effect on the development of culture are discussed, as is the liquidation of censorship. The transition of publishing from a monopoly state enterprise to a part of the market economy is described, along with the development of the new mass electronic media. A final section deals with the situation in public libraries after 1989 and the difficulties experienced by librarians in dealing with the threatened disappearance of traditional culture under the tidal wave of mass media for entertainment.     

��Information Survival Skills��: a medical school elective

Objective:

The authors developed an elective course to assist students in (1) understanding the changing nature of scholarly communication and online publishing, (2) identifying resources and strategies for searching current best evidence, and (3) demonstrating effective communication of information.

Setting:

The course took place in a medical school in the Southwest.

Participants:

Second- and third-year medical students participated in the course.

Intervention:

A pass-fail, undergraduate-level elective was first offered October to December 2006. This 7.5 hour course, developed and co-taught by 2 health sciences library faculty, consisted of hands-on exercises, small group discussion, and didactic lecture.

Conclusion:

Presenting a medical school elective is one possible outlet for intensive bibliographic instruction. Illustrating the flow of information from creation to management and presentation affords students an opportunity to understand information in context. This elective has been consistently ranked very high in student evaluations and led to new and expanded teaching opportunities.     

Fixed or flexible schedule? Schedule impacts and school library circulation

Despite more than 15 years of research into the implementation of flexible access to school library media programs in the United States, few empirical studies exist that examine the relationship between access scheduling and school library media circulation. This quantitative study examines the relationship between types of school library schedules and circulation. Examination of end-of-year circulation statistics for fixed, flexible, and partially flexible elementary school library media centers in North Carolina and Virginia indicate that there was a significant and positive relationship between flexible scheduling and per-pupil book circulation in elementary schools in these two states.     

Modeling users’ search sessions for high utility query recommendation

Query recommendation has long been considered a key feature of search engines, which can improve users’ search experience by providing useful query suggestions for their search tasks. Most existing approaches on query recommendation aim to recommend relevant queries, i.e., alternative queries similar to a user’s initial query. However, the ultimate goal of query recommendation is to assist users to reformulate queries so that they can accomplish their search task successfully and quickly. Only considering relevance in query recommendation is apparently not directly toward this goal. In this paper, we argue that it is more important to directly recommend queries with high utility, i.e., queries that can better satisfy users’ information needs. For this purpose, we attempt to infer query utility from users’ sequential search behaviors recorded in their search sessions. Specifically, we propose a dynamic Bayesian network, referred as Query Utility Model (QUM), to capture query utility by simultaneously modeling users’ reformulation and click behaviors. We then recommend queries with high utility to help users better accomplish their search tasks. We empirically evaluated the performance of our approach on a publicly released query log by comparing with the state-of-the-art methods. The experimental results show that, by recommending high utility queries, our approach is far more effective in helping users find relevant search results and thus satisfying their information needs.     

Interpersonal communication in high tech culture: Eastern or western?

This study investigates interpersonal communication in a high tech organization to determine whether practices are more Eastern or Western. Information gathered from organizational practice and participant observations comprise the data. The organization emerges significantly Western on seven of nine categories. The external environment, organizational mission, and life cycle stage are offered as explanations for these findings. Results suggest that this organization would not be a suitable candidate for Japanese management practices.     

Gender and research publishing in India: Uniformly high inequality?

Women’s access to academic careers has been historically limited by discrimination and cultural constraints. Comprehensive information about gender inequality within disciplines is needed to understand the problem and target remedial action. India is the fifth largest research producer but has a low international index of gender inequality and so is an important case. This study assesses gender inequalities in Indian journal article publishing in 2017 for 186 research fields. It also seeks overall gender differences in interests across academia by comparing the terms used in 27,710 articles with an Indian male or female first author. The data show that there are at least 1.5 male first authors per female first author in each of 26 broad fields and 2.8 male first authors per female first author overall. Compared to the USA, India has a much lower share of female first authors but smaller variations in gender differences between broad fields. Dentistry, Economics and Maths are all more female in India, but Veterinary is much less female than in the USA. There is a tendency for males to research thing-oriented topics and for females to research helping people and some life science topics. More initiatives to promote gender equality in science are needed to address the overall imbalance, but care should be taken to avoid creating the larger between-field gender differences found in the USA.     

Short‐term effects of an anti‐marijuana media campaign targeting high sensation seeking adolescents

Sensation seeking, a biologically‐based personality variable, is strongly related to both drug use and preferences for highly novel, arousing, and/or unconventional messages and TV programs. This connection is the basis of a targeting strategy in an anti‐marijuana public service announcement campaign in a medium‐sized market aimed at high sensation seeking adolescents. Data from the first half of the media campaign suggest that the anti‐marijuana PSAs are reaching the target audience's marijuana‐related beliefs, attitudes, and behaviors in the experimental city when compared to the control city. Implications for future campaigns are discussed.     

The land of confusion?: High school students and their use of the World Wide Web for research

The use of the World Wide Web by high school students to complete school assignments was studied by interviewing high school students. The author expected to find that students were using the World Wide Web as their primary source of information and that the students had difficulty in evaluating whether information on a web site was scholarly. The author considered Perry's Scheme of Student Development and the unique nature of the World Wide Web to come to these assumptions, which were only partially validated by this study. As is typical in a qualitative study, the sample was small, but some themes that could help provide direction to further research emerged. It was discovered that the students in the study used a good variety of resources, including libraries and the World Wide Web, to find information for school assignments. However, the students were weak at determining the quality of the information that they found on a web site. Students did poorly at evaluating web site information in the absence of gatekeepers.     

Does high e-government adoption assure stronger security? Results from a cross-country analysis of Australia and Thailand

We present the first comprehensive audit and comparison of e-government website security in two countries. Australia was selected for its high level of e-government adoption, while Thailand was selected in contrast as a developing nation. Through our audit of 800 pages across 40 websites, we reveal numerous security vulnerabilities suggesting that the high adopters of e-government may not always be providing better protection to their citizens. Alarmingly, the most basic web security measure, the use of Hypertext Transfer Protocol Secure encryption was only used in half of Australian and one-third of Thai sites. Our methodology included content analysis of policies and encryption, followed by security vulnerability testing, to provide the first baseline data on these two countries. Statistical analysis suggests that far from being the benchmark for security, Australian e-government sites do not significantly differ from Thai sites in their vulnerability level. The implications of these findings are examined, and recommendations are made for practice. It is hoped that these insights into the current state of security provide a needed stimulus to focus more on the practical information security aspects of e-government.     

On the formation of very high competencies in bachelor’s degree students using information and communication technologies

This paper describes the experience on revealing problems in knowledge of information and communication technologies (ICTs) by undergraduate students and the development of a training scheme using ICT tools for individualizing the formation of the competencies defined by a basic educational program, which helps to manage human capital in the training of modern staff.     

The persuasive effects of delaying identification of high‐and low‐credibility communicators: A meta‐analytic review

A review of extant research evidence indicates that when source identification is delayed until after the message has been presented, the differential effectiveness of high‐ and low‐credibility communicators is reduced. In particular, those combinations of credibility level and advocated position that are ordinarily (i.e., with pre‐message identification) relatively advantageous (a low‐credibility source with a proattitudinal position, or a high‐credibility source with a non‐proattitudinal position) have persuasive effectiveness reduced by delayed identification, whereas those combinations that are ordinarily relatively disadvantageous (a high‐credibility source with a proattitudinal position, or a low‐credibility source with a non‐proattitudinal position) enjoy enhanced effectiveness with delayed identification. The magnitude of the effects associated with identification‐timing variations is quite large (mean absolute value of d = .753), at least by comparison to other factors for which quantitative estimates of persuasive effect are available. The observed effects place constraints on explanations of credibility's effects; in particular, credibility's effects cannot be explained through the mere association of a given communicator with a particular position.     

There’s a creepy guy on the other end at Google!: engaging middle school students in a drawing activity to elicit their mental models of Google

Although youth are increasingly going online to fulfill their needs for information, many youth struggle with information and digital literacy skills, such as the abilities to conduct a search and assess the credibility of online information. Ideally, these skills encompass an accurate and comprehensive understanding of the ways in which a system, such as a Web search engine, functions. In order to investigate youths’ conceptions of the Google search engine, a drawing activity was conducted with 26 HackHealth after-school program participants to elicit their mental models of Google. The findings revealed that many participants personified Google and emphasized anthropomorphic elements, computing equipment, and/or connections (such as cables, satellites and antennas) in their drawings. Far fewer participants focused their drawings on the actual Google interface or on computer code. Overall, their drawings suggest a limited understanding of Google and the ways in which it actually works. However, an understanding of youths’ conceptions of Google can enable educators to better tailor their digital literacy instruction efforts and can inform search engine developers and search engine interface designers in making the inner workings of the engine more transparent and their output more trustworthy to young users. With a better understanding of how Google works, young users will be better able to construct effective queries, assess search results, and ultimately find relevant and trustworthy information that will be of use to them.     

The changing role of school/media resource libraries in secondary schools in Singapore and the need to implement mandatory standards, 1946–2010: Issues,challenges and opportunities

The aim of this paper is to study the development and evolution of secondary school libraries into Media Resource Libraries (MRLs) in Singapore after the Second World War and the rationale to have mandatory school library standards. It is an historical survey analysing published data about the linkages of libraries and librarianship, school library standards, education and school reforms in Singapore. It analyses historical and current documents on the roles played by stakeholders like the Library Association of Singapore (LAS) and the Ministry of Education (MOE) in the introduction and development of school library standards. The need for school libraries standards was first discussed when the Malayan Library Group (MLG) organised the first course on librarianship for school teachers in 1955, but, with no follow through. The need for school libraries standards was also mentioned by the LAS in 1962 in a memorandum to the Commission of Enquiry into Education to train teacher librarians and adopt school library standards. However, this was left out in the final report of the Commission published in 1964. The need for school library standards was discussed in a school library seminar for 150 teacher librarians in 1970. The first Recommended Minimum Standards for Secondary School Libraries was published two years later by the Standing Committee on Libraries set up by the MOE, but it was not mandatory for schools to adopt the standards. In 1997 the MOE launched its “Thinking School Learning Nation” vision to teach thinking skills. Students were expected to do multidisciplinary project work and be independent users of information. The MOE began to convert school libraries into Media Resource Libraries (MRLs) with print and non-print materials. However, a survey conducted in 2001 on the roles and competencies of 112 Library Coordinators (LCs) or teacher librarians revealed that they lack the skills and knowledge to manage MRLs effectively. This is because subsequent school library standards published in 1983 and 2002 did not require trained and full-time teacher librarians to manage the MRLs. Furthermore, it is essential for the standards to be periodically updated with regards to professional staff, collection development, facilities, Information and Communications Technology (ICT) infrastructure and school library programs. Otherwise, MRLs risk being “hollow shells still considered on the periphery of core educational requirements, and are run by teachers not professionally prepared to do the work” (Hart, 2001, p. 25). The national standards published in the United States from 1918 to 2008 are well researched and provide substantive guidelines to develop school libraries. Therefore, it is essential for the MOE to formulate MRL standards by doing comparative studies of school library standards in other countries. These standards have to be mandatory and fully adopted by the schools. It provides opportunities for stakeholders like the LAS, National Library Board (NLB), the National Institute of Education (NIE), and the Singapore Teachers’ Union, to collaborate in the formulation of these standards and take collective ownership to implement them.     

“My mother can't quite understand why I decided to go to library school”: What patrons say about library staff when asking government documents reference questions at depository libraries

This article examines the written comments of proxies participating in an unobtrusive nationwide study of government documents reference service in Canada. Proxies submitted overviews about the quality of reference service they received. On the whole, proxies were disappointed in how they were treated by depository library staff. For example, reference personnel were criticized for providing numerous unmonitored referrals, telling users that the questions were too difficult, and for not being sufficiently knowledgeable about government documents. Some aspects of reference service, such as use of multiple sources and collaboration among staff, received positive comments. Proxies also made a number of salient recommendations for improving government documents reference service in Canada. If depository libraries are to survive as vital links in the transmission of government information to the public, the knowledge level and service ethic of staff needs significant improvement.
