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   

Granularity of algorithmically constructed publication-level classifications of research publications: Identification of topics     

Peter Sjögårde  Per Ahlgren 《Journal of Informetrics》2018,12(1):133-152

The purpose of this study is to find a theoretically grounded, practically applicable and useful granularity level of an algorithmically constructed publication-level classification of research publications (ACPLC). The level addressed is the level of research topics. The methodology we propose uses synthesis papers and their reference articles to construct a baseline classification. A dataset of about 31 million publications, and their mutual citations relations, is used to obtain several ACPLCs of different granularity. Each ACPLC is compared to the baseline classification and the best performing ACPLC is identified. The results of two case studies show that the topics of the cases are closely associated with different classes of the identified ACPLC, and that these classes tend to treat only one topic. Further, the class size variation is moderate, and only a small proportion of the publications belong to very small classes. For these reasons, we conclude that the proposed methodology is suitable to determine the topic granularity level of an ACPLC and that the ACPLC identified by this methodology is useful for bibliometric analyses.  相似文献

Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows

Known as the ‘third polar region’, the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there. Previous studies of birds, animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence. The adaptive processes during the initial phase of highland adaptation remain poorly understood. We studied a human commensal, the Eurasian Tree Sparrow, which has followed human agriculture to the Qinghai-Tibet Plateau. Despite strong phenotypic differentiation at multiple levels, in particular in muscle-related phenotypes, highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years. In a one-month acclimation experiment investigating phenotypic plasticity, we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes. Through population genetic analyses, we identified a signature of polygenic adaptation, whereby shifts in allele frequencies are spread across multiple loci, many of which are associated with muscle-related processes. Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution, shedding light on early stages of adaptive evolution to a novel environment.  相似文献   

Relationship Reciprocation Modulates Resource Allocation in Adolescent Social Networks: Developmental Effects          下载免费PDF全文

Stephanie Burnett Heyes  Yeou‐Rong Jih  Per Block  Chii‐Fen Hiu  Emily A. Holmes  Jennifer Y. F. Lau 《Child development》2015,86(5):1489-1506

Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: N = 42, ages 13–17; Study 2: N = 81, ages 13–16) investigated age group differences in the impact of relationship reciprocation within school‐based social networks on an experimental measure of cooperation behavior. Results suggest development between mid‐ and late adolescence in the extent to which reciprocation of social ties predicted resource allocation. With increasing age group, investment decisions increasingly reflected the degree to which peers reciprocated feelings of friendship. This result may reflect social‐cognitive development, which could facilitate the ability to navigate an increasingly complex social world in adolescence and promote positive and enduring relationships into adulthood.  相似文献

Managing research and innovation networks: Evidence from a government sponsored cross-industry program     

Per Levén  Jonny Holmström  Lars Mathiassen 《Research Policy》2014

Important innovations are increasingly produced based on research engagement and fertilization across industries. However, we know little about the challenges associated with managing innovation networks in specific contexts that involves researchers in cross-industry collaboration. Against this backdrop, we draw on theory on design and orchestration of innovation networks to analyze a large-scale government sponsored program, “ProcessIT Innovations” that was designed to increase competitiveness and accelerate economic growth in Northern Sweden. The program was initiated and led by firms from the traditionally strong local process industry and engaged local researchers and firms from the emerging IT industry. Based on our analyses, we offer two contributions. First, we provide a detailed analysis of the challenges related to configuration of the network, orchestration of partnerships between participants, and facilitation of innovation in dedicated development projects. Second, we propose a model of managing research and innovation networks through fertilization across industries and between firms and research institutions.  相似文献   

Mandatory coursework assignments can be,and should be,eliminated!     

John Haugan  Marius Lysebo  Per Lauvas 《European Journal of Engineering Education》2017,42(6):1408-1421

Formative assessment can serve as a catalyst for increased student effort and student learning. Yet, many engineering degree programmes are dominated by summative assessment and make limited use of formative assessment. The present case study serves as an example on how formative assessment can be used strategically to increase student effort and improve student learning. Within five courses of an engineering bachelor degree programme in Norway, the mandatory coursework assignments were removed and replaced by formative-only assessment. To facilitate the formative assessment, weekly student peer-assessment sessions were introduced. The main findings include an increase in student study hours and improved student performance on the examinations. Finally, interviews were conducted by an external consultant in an effort to identify key factors that attributed to the positive outcome.  相似文献   

RPL for accreditation in higher education – As a process of mutual understanding or merely lifeworld colonisation?     

Fredrik Sandberg  Per Andersson 《Assessment & Evaluation in Higher Education》2011,36(7):767-780

This article focuses on a process of recognition of prior learning (RPL) in higher education. It is based on experiences from a project carried out in collaboration between the University of Lund, Linköping University and two trade unions in Sweden. The aim of the project was to find ways of recognising prior learning for accreditation of course credits at university level. In the project and its analysis, Habermas’ theory of communicative action was used as theoretical underpinning. During the project we carried out a thematic analysis based on interviews. The analysis suggested that the participants had a mystified view of higher education that RPL must be considered a learning process and that the participants’ prior learning can be characterised as practical wisdom. These themes guided the development of the project. In a retrospective analysis, language proficiency seemed to play a significant role for the outcome of the process. The conclusion suggests that a more fair and valid assessment of the participant’s prior learning could be accomplished by focusing on RPL as a process of mutual understanding. However, a critical appraisal of the process suggests that RPL for accreditation is problematic and could be seen as a colonisation of the lifeworld.  相似文献   

Negative school factors and their influence on math and science achievement in TIMSS 2003     

Tina Vršnik Perše  Ana Kozina  Tina Rutar Leban 《Educational studies》2011,37(3):265-276

The aim of the present study was to conduct an analysis of TIMSS (Trends in International Mathematics and Science Study) 2003 database and to determine how negative school factors, such as aggression, are associated to the mathematical and science achievement of students. The analyses were conducted separately for national and international data. National analyses for Slovenia show significant associations between math and science achievement and the experience of aggressive behaviour. Students who experienced aggressive behaviour scored lower in math and science, both in the fourth and in the eighth grade. The results of the regression analysis show that negative factors, such as aggressive behaviour, are good predictors of educational achievement in Slovenia. International analyses for the selected countries (high‐ and low‐achieving countries from the whole TIMSS population) confirm that this type of finding is culturally impartial as well as valid for the level of achievement both in math and in science.  相似文献
