This article presents findings from the first year of the Harbingers research project started in 2015. The project is a 3‐year longitudinal study of early career researchers (ECRs) to ascertain their current and changing habits with regard to information searching, use, sharing, and publication. The study recruited 116 researchers from seven countries (UK, USA, China, France, Malaysia, Poland, and Spain) and performed in‐depth interviews by telephone, Skype, or face‐to‐face to discover behaviours and opinions. This paper reports on findings regarding discovery and access to scholarly information. Findings confirm the universal popularity of Google/Google Scholar. Library platforms and web‐scale discovery services are largely unmentioned and unnoticed by this user community, although many ECRs pass through them unknowingly on the way to authenticated use of their other preferred sources, such as Web of Science. ECRs are conscious of the benefits of open access in delivering free access to papers. Social media are widely used as a source of discovering scholarly information. ResearchGate is popular and on the rise in all countries surveyed. Smartphones have become a regularly used platform on which to perform quick and occasional searches for scholarly information but are only rarely used for reading full text. 相似文献

This study presents findings from the first year of the Harbingers research project, a 3‐year longitudinal study of early career researchers (ECRs), which sought to ascertain current and changing habits in scholarly communication. The study recruited 116 science and social science ECRs from seven countries who were subject to in‐depth interviews, and this paper reports on findings regarding publishing and authorship practices and attitudes. A major objective was to determine whether ECRs are taking the myriad opportunities proffered by new digital innovations, developing within the context of open science, open access, and social media, to publish their research. The main finding is that these opportunities are generally not taken because ECRs are constrained by convention and the precarious employment environment they inhabit and know what is best for them, which is to publish (in high impact factor journals) or perish. 相似文献

In the restoration-conservation practice of medieval art masterpieces, such as the Holy Lady Shrine from Huy, knowledge about the techniques used to create and shape them is of major importance, especially when they concern the surface finishing treatments. This influences the selection of methods employed for the conservation-restoration process. This paper discusses the method and the materials that might have been employed to modify the colour of gilding on silver. Recipes for chemically modifying the colour of the gilded surface can be found in medieval texts and might have been used on the masterpiece discussed in this paper. This article gives an overview of technical instructions related to this topic and presents a method to interpret their contents in order to be able to implement them. It reports observations carried out during the implementation tests, such as information about the temperature, timing, and other important elements. It concludes with the visual and the colorimetric results on the samples after application of the tested recipes. 相似文献

School violence has become of paramount concern in recent years, leaving many schools unprepared to deal with the varied problems students bring to the classroom. Conditions within the school can be readily identified that predict and contribute to problematic behavior. The success of preventive and intervention programs for youth violence hinges upon recognizing and modifying aspects of school climate, teacher/school personnel interactions with students, and school structure. Several of these aspects are identified in this article and suggestions for improving the educational environment to prevent the development of antisocial behaviors in youth are offered. © 2002 Wiley Periodicals, Inc. 相似文献

More women are now entering male-dominated fields, yet, science, technology, engineering, and mathematics (STEM) remain dominated by men. We examined the association between boys’ and girls’ STEM choices after secondary education and friends’ gender norms, and whether pressure to conform to traditional gender norms differs depending on the gender composition of the friend group. Drawing on 3 waves of longitudinal data (N?=?744) from the Netherlands, our sample consists of adolescents in STEM trajectories in secondary education. Their retention in STEM after secondary education gives us a better understanding of gender-specific “leakage” from the STEM pipeline. We found that girls’ likelihood of choosing STEM decreased drastically when friends had more traditional gender norms. Friends with traditional gender norms had less effect on boys. Nonetheless, boys with only same-sex friends were more likely to enter STEM. Our findings indicate that an environment with gender-normative ideas pushes girls out of the STEM pipeline. 相似文献
