Seeking Nettle Textiles – Utilizing a Combination of Microscopic Methods for Fibre Identification     

Jenni A. Suomela  Krista Vajanto  Riikka Räisänen 《文物保护研究》2018,63(7):412-422

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history.  相似文献   

Research trends and collaborations by applied science researchers in South African universities of technology: 2007–2017     

Elisha R.T. Chiware  Deborah A. Becker 《The Journal of Academic Librarianship》2018,44(4):468-476

This paper analyses the publication patterns of researchers in the field of applied sciences at Universities of Technology in South Africa. Aspects investigated include publications in SCOPUS-listed journals; number of citations and countries of publication. Collaborative research patterns at national and international levels were also investigated. A bibliometric analysis approach was followed using SCOPUS as the main source of data and analysing the articles published in selected applied science disciplines. Results show that researchers in the field of applied sciences in universities of technology have increased their number of publications over the past 10?years and are also working in conjunction with other researchers both nationally and internationally. The analysis is an important addition to the field in South Africa which helps in measuring how institutions are positively responding to government incentives in research. The results are also important to information professionals who are increasingly playing an important role in research impact assessments.  相似文献   

Google Scholar's Coverage of the Engineering Literature 10 years Later     

Carmen Cole  Angela R. Davis  Vanessa Eyer  John J. Meier 《The Journal of Academic Librarianship》2018,44(3):419-425

In 2008 Meier and Conkling first tested Google Scholar's coverage of the engineering literature against citations gathered from the Compendex database. Since that time, other studies have used the same methodology and found improvement in Google Scholar's coverage. This study uses engineering dissertations from Proquest Dissertations & Theses to create a data set of citations for the comparison of fee-based databases, Compendex and Scopus, against Google Scholar. From 1950 to 2017 Google Scholar outperformed both Compendex and Scopus in discoverability of citations in nine engineering subjects. These results have implications for collection management and information literacy program planning for librarians.  相似文献   

We May Be Teaching Information Literacy,but Are the Design First Year Students Actually Getting It?     

Debby R. Wegener 《The Journal of Academic Librarianship》2018,44(5):633-641

The purpose of this study was to examine the outcomes of information literacy instruction for the Design first year students at the Temasek Polytechnic Library. Also of interest was whether or not the librarian was being seen as easily approachable, and if the students were deeming the lessons to be worthwhile. A participant action research approach was used, with the data being collected from multiple choice tests delivered via the institutional learning management system, group exercises, and a diagnostic assessment that was delivered before the workshops. It was found that the students did see the librarian as someone who was eminently approachable, and the majority of them found the lessons to be of value. It was concluded that the use of a diagnostic tool can be very useful in highlighting the gaps in students' knowledge, and that it would be beneficial to use it for all information literacy instruction at TP. Suggested future research could include a study of how much the students retain of IL skills into their third year of study.  相似文献   

The Constitutive Relationship of Social Communication Competence to Self-Compassion and Hope     

Laura R. Umphrey  John C. Sherblom 《Communication Research Reports》2018,35(1):22-32

Communication is constitutive—in theory. In research, however, communication is often treated as an outcome, influenced by personal attributes. The present research examines social communication competence as a constitutive influence predicting self-compassion and hope. Path analysis results support this hypothesis. Results show that social communication expressivity (β = .14), sensitivity (β = –.32), and control (β = .20) predict self-compassion. Social communication sensitivity (β = .26) and control (β = .27) affect hope agency, and social communication control (β = .29) predicts hope pathways thinking. These results provide evidence of the constitutive nature of communication.  相似文献   

Narrative Persuasion in a New Media Environment: The Impact of Binge-Watching and Second-Screening     

Nathan Walter  Sheila T. Murphy  Erica L. Rosenthal 《Communication Research Reports》2018,35(5):402-412

The study explored the role of second-screen use and binge-watching in moderating entertainment education (EE) effects. A pretest/posttest experiment of 273 viewers of East Los High measured the effects of exposure to three subplots, concerning alcohol abuse, abortion, and immigration. The effect of identification with characters on change in attitudes was significantly moderated by second-screen use and binge-watching. In particular, second-screening tended to enhance the positive impact of identification; whereas, among respondents who binge-watched the show, the effects of identification were weaker.  相似文献   

Social Comparisons and Need Fulfillment: Interpreting Video Game Enjoyment in the Context of Leaderboards     

John A. Velez  David R. Ewoldsen  Michael D. Hanus  Hyunjin Song  Jonathan A. Villarreal 《Communication Research Reports》2018,35(5):424-433

This study examines how social comparison information provided by video game leaderboards may influence players’ retrospective judgments of autonomy, competence, and relatedness need fulfillment. Participants played a video game and were randomly assigned to receive no postgame feedback or were shown a leaderboard that placed them in the top or bottom quartile of players. Results indicate downward social comparisons increase enjoyment by increasing competence and relatedness perceptions. However, upward comparisons did not have an opposite effect, nor did either type of social comparison influence players’ autonomy perceptions. Implications for applying Self-Determination Theory to video game enjoyment in the context of social comparison feedback is discussed.  相似文献
