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   

The Formation of Swedish Media Studies, 1960–1980     

Mats Hyvönen  Pelle Snickars  Per Vesterlund 《Media History》2018,24(1):86-98

Around 1960, the politics of the emerging media society in Sweden tended to fixate the formative functions of mass communication. The monopoly of public service broadcast media, press subsidies and new tendencies in film policy were some of the issues around which uncertainty prevailed. New methods to provide reliable data were sought by politicians, since empirical facts were required as arguments for an updated media policy. This article examines the different ways that the field of media studies was introduced in Sweden between 1960 and 1980. We argue that Swedish academic media studies departed from, and emerged within, a rather diffuse borderland between industry, politics and academia. The formation of national media research in Sweden can partly be seen as an effect of politicians and the media industry wanting to be better informed on issues such as media influence, media ownership and the habits and composition of the media audience.  相似文献   

Developmental links of very early phonological and language skills to second grade reading outcomes: strong to accuracy but only minor to fluency     

Puolakanaho A  Ahonen T  Aro M  Eklund K  Leppänen PH  Poikkeus AM  Tolvanen A  Torppa M  Lyytinen H 《Journal of learning disabilities》2008,41(4):353-370

The authors examined second grade reading accuracy and fluency and their associations via letter knowledge to phonological and language predictors assessed at 3.5, 4.5, and 5.5 years in children in the Jyv?skyl? Longitudinal Study of Dyslexia. Structural equation modeling showed that a developmentally highly stable factor (early phonological and language processing [EPLP]) behind key dyslexia predictors (i.e., phonological awareness, short-term memory, rapid naming, vocabulary, and pseudoword repetition) could already be identified at 3.5 years. EPLP was significantly associated with reading and spelling accuracy and by age with letter knowledge. However, EPLP had only a minor link with reading fluency, which was additionally explained by early letter knowledge. The results show that reading accuracy is well predicted by early phonological and language skills. Variation in fluent reading skills is not well explained by early skills, suggesting factors other than phonological core skills. Future research is suggested to explore the factors behind the development of fast and accurate decoding skills.  相似文献   

Between two Advisors: Interconnecting Academic and Workplace Settings in an Emerging Field     

Kaisa Hytönen  Tuire Palonen  Erno Lehtinen  Kai Hakkarainen 《Vocations and Learning》2016,9(3):333-359

This article examines a new training design for continuing professional development that aims to support the learning of the novel knowledge and skills needed in emerging professional fields by interconnecting academic and workplace settings. The training design is based on using two advisors, one from working life and the other from an academic context. The article examined whether participants’ personal orientation to adaptive expertise predicts the success of a guidance process. The interconnection of workplace and academic contexts was expected to occur through guidance practices. In addition, the features underlying the most successful guidance relationships were analysed. Data were collected by conducting repeated semi-structured interviews with 18 course participants, eight academic advisors and eight workplace advisors in the context of a 1-year energy efficiency training programme. The results indicated that a trainee’s personal orientation towards adaptive expertise is a significant component in successful guidance processes. An interconnection of workplace and academic knowledge and practices was hardly found in the guidance provided by each participant’s academic and workplace advisors. The feature underlying the most successful guidance relationships are related at the personal, dyad and context levels. An excellent match between the expert profiles of the learner and the advisor appears to be especially critical for successful guidance and powerful knowledge exchange in emerging fields. However, finding matching advisors is often challenging. Many problems are presumably solved if these ‘right persons’ can be found and if the trainees are themselves oriented to utilise the novel resources provided to them by the advisors.  相似文献   

Cultural Sustainability in Art‐Based Interdisciplinary Dialogue     

Elina Hrknen  Antti Stckell 《The International Journal of Art & Design Education》2019,38(3):639-648

This article introduces an international and interdisciplinary summer school, ‘Living in the Landscape’ (LiLa) in 2018. LiLa's practices focused on creating dialogue among art education, anthropology and nature science and developing culturally sustainable methods for investigating cultural heritage in the Komi Republic of Russia. The article's research interest is how dialogue and cultural heritage appear in the artistic processes, artworks and final exhibition of the summer school. These are examined through art‐based action research in order to develop international, multidisciplinary and culturally sustainable art education. The four‐field model utilised in the research highlights the multidimensional role of dialogue in both individual and collaborative artistic endeavours.  相似文献

Young Diplomats?? Socialization to the Networked Professional Cultures of Their Workplace Communities     

Kaisa Hyt?nen  Kai Hakkarainen  Tuire Palonen 《Vocations and Learning》2011,4(3):253-273

The purpose of the present investigation was to examine young diplomats’ socialization to the professional expert culture of the Ministry for Foreign Affairs of Finland over a six-month on-job training period, as part of their preparation for service in the diplomatic corps. Using social network analysis, we analyzed departments’ internal social structures, prevailing social relations, and the young diplomats’ role and position in the networks of knowledge acquisition, practical know-how, and professional collaboration. Data collected by contextual event sampling and theme interviews and analyzed by qualitative content analysis were used to characterize the young diplomats’ personal social support networks, resources obtained, as well as associated reflections regarding their functioning in and socialization to the departmental workplace community. The results indicated that across the six-month training period, the young diplomats became involved to the workplace communities’ networked expertise and were socialized to its expert culture, even if their achieved networking positions differed. The results revealed differences between levels of collective operational practices in the workplace communities as well as the nature of assignments in which the young diplomats participated and for which they were responsible. It was proposed that these differences mirrored distinction between expansive natures of young diplomats’ workplace communities as learning environments.  相似文献   

Learning mechanisms in multidisciplinary teamwork with real customers and open-ended problems     

Juho Heikkinen  Ville Isomöttönen 《European Journal of Engineering Education》2015,40(6):653-670

Recently, there has been a trend towards adding a multidisciplinary or multicultural element to traditional monodisciplinary project courses in computing and engineering. In this article, we examine the implications of multidisciplinarity for students' learning experiences during a one-semester project course for real customers. We use a qualitative research approach and base our analysis on students' learning reports on three instances of a project course titled Multidisciplinary working life project. The main contribution of this article is the unified theoretical picture of the learning mechanisms stemming from multidisciplinarity. Our main conclusions are that (1) students generally have a positive view of multidisciplinarity; (2) multidisciplinary teams enable students to better identify their own expertise, which leads to increased occupational identity; and (3) learning experiences are not fixed, as team spirit and student attitude play an important role in how students react to challenging situations arising from introduction of the multidisciplinarity.  相似文献
