Abstract

As digital natives enter higher education, there is the need to improve their information skills but they often overestimate their information research skills and are unfamiliar with the library. The serious games give the opportunity for innovative and engaging approaches to information literacy learning. The paper describes NAVIGATE - Information Literacy: a Game-based Learning Approach for Avoiding Fake Content, a project funded by Erasmus?+?program. The Project aims to improve the competences to avoid fake content of the higher education students in the Humanities. The paper focuses on the comparative analysis of the students’ skills gap and the difficulty of actually assessing the learning improvement achieved by games, highlighting the lessons learned and the open issues.  相似文献

Using disposition theory as a framework, this 2 (headscarf vs. no headscarf) by 2 (US citizen vs. refugee) experiment sought to elucidate the impact of visual and verbal cues in mediated messages on conclusions drawn from a television news package about a woman accused of consorting with a known terrorist group in the US, in terms of parochial empathy for and perceived innocence of the woman. Parochial empathy measures the difference between ingroup and outgroup empathy; higher levels indicate ingroup empathy is greater than outgroup empathy, meaning the individual’s empathy is very narrow in scope or “parochial.” Political identity was a measured independent variable. The data supported a model in which political identity was a significant moderator of the headscarf’s effect on parochial empathy, and that parochial empathy mediated the relationship between the manipulated and measured predictor variables on perceived innocence. Details of the relationships among variables are reported and the implications for theory and journalism practice are discussed.  相似文献

The study reports on a longitudinal and comparative evaluation of Greek language searching on the web. Ten engines, five global (A9, AltaVista, Google, MSN Search, and Yahoo!) and five Greek (Anazitisi, Ano-Kato, Phantis. Trinity, and Visto), were evaluated using (a) navigational queries in 2004 and 2006; and (b) by measuring the freshness of the search engine indices in 2005 and 2006. Homepage finding queries for known Greek organizations were created and searched. Queries included the name of the organization in its Greek and non-Greek, English or transliterated equivalent forms. The organizations represented ten categories: government departments, universities, colleges, travel agencies, museums, media (TV, radio, newspapers), transportation, and banks. The freshness of the indices was evaluated by examining the status of the returned URLs (live versus dead) from the navigational queries, and by identifying if the engines have indexed 32480 active (live) Greek domain URLs. Effectiveness measures included (a) qualitative assessment of how engines handle the Greek language; (b) precision at 10 documents (P@10); (c) mean reciprocal rank (MRR); (d) Navigational Query Discounted Cumulative Gain (NQ-DCG), a new heuristic evaluation measure; (e) response time; (f) the ratio of the dead URL links returned, (g) the presence or absence of URLs and the decay observed over the period of the study. The results report on which of the global and Greek search engines perform best; and if the performance achieved is good enough from a user’s perspective.  相似文献

Dielectrophoresis (DEP) of biomolecules has large potential to serve as a novel selectivity parameter for bioanalytical methods such as (pre)concentration, fractionation, and separation. However, in contrast to well-characterized biological cells and (nano)particles, the mechanism of protein DEP is poorly understood, limiting bioanalytical applications for proteins. Here, we demonstrate a detailed investigation of factors influencing DEP of diagnostically relevant immunoglobulin G (IgG) molecules using insulator-based DEP (iDEP) under DC conditions. We found that the pH range in which concentration of IgG due to streaming iDEP occurs without aggregate formation matches the pH range suitable for immunoreactions. Numerical simulations of the electrokinetic factors pertaining to DEP streaming in this range further suggested that the protein charge and electroosmotic flow significantly influence iDEP streaming. These predictions are in accordance with the experimentally observed pH-dependent iDEP streaming profiles as well as the determined IgG molecular properties. Moreover, we observed a transition in the streaming behavior caused by a change from positive to negative DEP induced through micelle formation for the first time experimentally, which is in excellent qualitative agreement with numerical simulations. Our study thus relates molecular immunoglobulin properties to observed iDEP, which will be useful for the future development of protein (pre)concentration or separation methods based on DEP.  相似文献

Although still a side issue in the German-language media, attention towards synthetic biology has risen clearly during the last years, in line with the first applications being presented. This paper presents findings from a content analysis of synthetic biology coverage in German-language media over the years 2004-2009. In the media, synthetic biology is not clearly separated from gene technology. News value is attributed to established categories such as persons and events. Many metaphors and analogies used in describing gene technology can also be found in the coverage of synthetic biology; however, engineering metaphors are more prominent. In addition, playfulness constitutes an aspect rarely found in genetic engineering coverage. Overall, the picture emerging is ambivalent, which leaves prospects for the further development of public debate ambiguous.  相似文献

In this paper, we present the results of a research programme we developed to investigate the professional identity of preschool education teachers in Greece. Our aim was to investigate parameters affecting not only the creation but also the reform of professional identity and to highlight potential differences in terms of professional identity. Contemporary approaches to professional identity – developed since the 80s – raise issues related primarily to participatory processes, reflection, autonomy and emancipation. Teachers’ professional identity is gradually developed through an ongoing process of three interrelated and complementary steps: (a) pre-service teacher education, (b) vocational integration and (c) exercise of professional duties and in-service training. We interviewed 20 teachers on their professional identity. We chose two categories of teachers based on two criteria: (a) their studies, and (b) their professional experience in the field. Tentative findings showed that professional experience was more important than studies in the construction of their professional identity. Professional identity also relates to both their professional experience and the dominant beliefs about early childhood education.  相似文献

From its beginning in 1885, the Hull House was beacon for social progress and urban reform. Founders Jane Addams and Ellen Gates Starr recruited talented, passionate partners from diverse fields to address issues from street sanitation to education in Chicago’s immigrant communities. Among residents’ many projects, their involvement in the “social hygiene” movement for sex education and contraception is perhaps the least recognised, in part because the Hull House did not save materials directly related to these services. As a result, the professional activities of Hull House residents Drs Rachelle Yarros and Alice Hamilton reveal a productive relationship between the Hull House and the social hygiene movement. Part of their critical work was to dismantle the cultural association of contraceptives and sex education with “fallen women” and reframe these services as necessities for maternal health. The papers of their professional organisations chronicle their delicate efforts to challenge assumptions about reproductive healthcare while preserving Victorian ideals about sex as a private, procreative endeavour strictly between married, monogamous people. Rachelle Yarros was particularly active, producing a dearth of literature on sexual health, teaching classes on the subject, and overseeing the opening of Chicago’s first public birth control clinics. Each of these advancements, including the birth control clinic, was available on Hull House grounds. By capitalising on the financial and medical resources available to them as physicians and reformers, Yarros and Hamilton achieved significant gains in women’s healthcare and initiated a national conversation about sexual health as a human right.  相似文献

Libraries and archives are increasingly under pressure to justify the cost of preserving the recorded heritage. This paper addresses the real need to identify and measure the benefits of preservation of the recorded heritage in the UK.

Stated preference techniques are well established in the field of environmental economics, and they are also appropriate for the valuation of cultural heritage. The authors develop and test a methodology to estimate people's preferences for the preservation of the recorded heritage through two stated preference case (pilot) studies.

All library and archive materials supporting the written and documentary heritage of the chosen case studies have been considered. The benefits of preservation are identified as those associated with the use of the recorded heritage (for example, by schools, commercial organisations, academics and other interested parties), the option of using it in the future, and the value placed on its existence by the general public, even if they have no intention of using it.

The main advantage of estimating the benefits of preservation in monetary terms is that these can be compared with the costs of preservation to determine whether any given project or policy is worthwhile, or indeed to choose among competing projects for the allocation of funds.  相似文献

Students’ personal predictors of academic success are particularly relevant for first-year college students, given the specific challenges that these students face when entering higher education (HE). Academic success in HE has been related to multiple factors, including the students’ approaches to learning (SAL), satisfaction (linked to commitment and persistence), study time (effort), and prior academic achievement. This study analyzes the combined effect of these predictors on perceived academic success. Data from 247 students was collected using the Approaches and Study Skills Inventory for Students and other specific measures to assess presage and process variables of academic success. Although academic success is multidimensional and difficult to explain, factors such as prior academic achievement, satisfaction with the course, SAL, and study time contribute to explain perceived academic success in first-year college students.  相似文献
