The purpose of this article is to analyse how students use inscriptions as tools for thinking and learning in mathematical problem-solving activities. The empirical context is that of learning about geometric series in a small group setting. What has been analysed is how students made use of inscriptions, self-made as well as those provided by text books and teachers, and the role these inscriptions played in the coordination of students' learning/communication. Through the use of inscriptions (made on the chalkboard and with paper and pencil), the students externalised their thinking while engaging in mathematical reasoning on the topic of geometric series. The inscriptions were significant as anchor points for arguments in the ongoing discussions. Three main issues are highlighted: (a) how the inscriptions used contribute to the process of appropriation, (b) how the students use inscriptions to externalise and clarify their ideas and attempts at meaning-making, and (c) how the inscriptions are conducive to closing the gap between the original problem as given in the text book and the mathematisation necessary. It is argued that inscriptions, through their material nature, play a decisive role in learning mathematical reasoning. (Contains 3 figures and 5 notes.)

Google Docs and EtherPad are Web 2.0 tools providing opportunity for multiple users to work online on the same document consecutively or simultaneously. Over the last few years a number of research papers on the use of these collaborative tools in a teaching and learning environment have been published. This work builds on that of Brodahl, Hadjerrouit, and Hansen (2011) expanding its case study. The theoretical framework is the same as the one underlying Brodahl et al. (2011), drawing on two learning theories, the social-constructivist learning theory and the community of practice, and their relationships to collaborative tools. The literature review is extended to cover the recent research work in the field, related to Web 2.0 technologies in higher education. The case study of Brodahl et al. (2011) involved 201 education students who had just begun their four-year initial teacher education. However, 24 students are omitted in the current work, and the result tables from Brodahl et al. (2011) accordantly updated. Disregarding particular groups of students was due to their specific local dispersion, as they conducted their entire assignment and collectively reflective essay paper at the same physical location and, with respect to this, reported the use of collaborative tools as superfluous and unwanted in their setting. Partly based on the same survey, this work presents a case study investigating education students' perceptions of collaborative writing reflective essay papers. However, where Brodahl et al. (2011) presented a solely quantitative study derived from closed-ended questions, this work incorporates the survey's open-ended questions in a qualitative analysis. The analysis also draws on the students' written reflections on their experiences. The qualitative analysis supports the conclusion of Brodahl et al. (2011) that technical problems were a major issue, mostly related to EtherPad. All but one complaint about technical difficulties stemmed from EtherPad users during a limited period of time. Other major negative feedback concerned group size; several groups pointed out difficulties with organizing the work, problems of keeping track when editing simultaneously, and failure to produce a unified document. Positive issues frequently mentioned are the ability to work asynchronously and from different places. Furthermore, a majority of the reports on commenting on and editing each other's work were positive, mentioning that it is an advantage to be able to correct spelling errors and bad formulations, that it is educational, that one may contribute with ideas that the others do not have, and that it improves the final text. Larger issues on the negative side were fear of insulting or misunderstanding, and difficulties because of various work modes. Also qualitative results indicate that females are more concerned with group size than males, but less preoccupied with technical difficulties. Furthermore, younger students appear more concerned about the importance of preparation and planning than older ones. The major conclusions are that EtherPad and Google Docs facilitate new ways of approaching communication, for different collaborative writing work modes as well as in different settings. However, the setting in which the tool is used exerts an influence on the way students perceive its usefulness. Recommendations derived from students' perception of factors of success for using the collaborative writing tool include the following: group size should preferably not exceed three persons; the students ought to be prepared for technical difficulties and have a contingency plan; and they should have time in advance to discuss their work mode and agree on rules for commenting on and editing each other's work.

Objectives: The objective of the present study was to investigate the risk of death from non-malignant diseases in female pulp and paper workers in Norway., Methods: A total of 3143 women first employed between 1920-93 were included in the study cohort. Information about each cohort member was obtained from personnel record files in the mills in order to identify employment periods and job categories. Data on cause and date of death were added by linkage to the Cause of Death Register using unique personal identification numbers. The follow up period was 1951-2000. Standardised mortality ratios (SMRs) with 95% confidence intervals (95% CIs) were calculated using the national female mortality rates as reference. Poisson regression analysis was used to examine internal relations between the duration of employment in paper departments and the risk of death from selected causes. Relative risks (RRs) and 95% CIs were calculated., Results: The study showed a significantly increased risk for total non-malignant mortality (SMR = 1.14, 95% CI 1.05 to 1.24), mainly due to increased mortality from ischaemic heart disease (SMR = 1.22, 95% CI 1.03 to 1.43) and cerebrovascular diseases (SMR = 1.16, 95% CI 0.94 to 1.42). Analysis by department showed the highest risk of death in paper department workers with short term employment. Internal analyses showed a 5% and 9% increase in risk of dying from ischaemic heart disease and respiratory diseases, respectively, among paper department workers exposed to paper dust. The risk decreased with increasing duration of employment., Conclusion: The increased risk of ischaemic heart diseases and respiratory diseases seen among employees of paper departments may be related to exposure to paper dust.

Objectives: A cohort study of female pulp and paper workers in Norway has shown a significantly increased risk of ovarian cancer. Other than the involvement of hormonal and reproductive factors, little is known of the etiology of ovarian cancer. Asbestos and talc are two agents hypothesized to influence the development of the disease. The present study aimed to investigate the association between ovarian cancer and occupational exposure to asbestos, talc, and total dust among Norwegian pulp and paper workers., Methods: Forty-six cases of ovarian cancer, with four controls each, were included in the study. Occupational exposure was assessed by combining work histories from personnel files, questionnaire information about production processes, and exposure assessments from the mills. To obtain information about possible confounders, cases and controls were invited to participate in a personal interview., Results: The odds ratio for asbestos exposure was 2.02, 95% confidence interval 0.72-5.66. For talc exposure, the odds ratio was 1.10, and for ever exposure to total dust, it was below 1.00. The risk estimates did not essentially differ after adjustment for possible confounding variables., Conclusions: The results do not confirm an association between exposure to asbestos, talc, and total dust and ovarian cancer among Norwegian pulp and paper workers. However, the odds ratio for asbestos exposure was doubled, and control for established nonoccupational risk factors did not change the estimate. Therefore, the possibility that exposure to substances in the work environment contributes to the elevated risk cannot be rejected.

The entirety of the sediment bed in lake Tyrifjorden, Norway, is contaminated by per- and polyfluoroalkyl substances (PFAS). A factory producing paper products and a fire station were investigated as possible sources. Fire station emissions were dominated by the eight carbon perfluoroalkyl sulfonic acid (PFSA), perfluorooctanesulfonic acid (PFOS), from aqueous film forming foams. Factory emissions contained PFOS, PFOS precursors (preFOS and SAmPAP), long chained fluorotelomer sulfonates (FTS), and perfluoroalkyl carboxylic acids (PFCA). Concentrations and profiles in sediments and biota indicated that emissions originating from the factory were the main source of pollution in the lake, while no clear indication of fire station emissions was found. Ratios of linear-to branched-PFOS increased with distance from the factory, indicating that isomer profiles can be used to trace a point source. A dated sediment core contained higher concentrations in older sediments and indicated that two different PFAS products have been used at the factory, referred to here as Scotchban and FTS mixture. Modelling, based on the sediment concentrations, indicated that 42–189 tons Scotchban, and 2.4–15.6 tons FTS mixture, were emitted. Production of paper products may be a major PFAS point source, that has generally been overlooked. It is hypothesized that paper fibres released from such facilities are important vectors for PFAS transport in the aquatic environment. Image 1 • Methods for tracking of PFAS point sources are demonstrated. • PFOS isomers were used for source tracking. • A factory producing PFAS coated paper products was identified as the main source. • A fate-and-transport model was employed to estimate emission volumes. • Production of paper products is likely a major source of environmental PFAS. A factory producing PFAS coated paper products is reported to be a PFAS point source. Emission volumes have been very large. Thus, such industry is an important, largely overlooked, source of environmental PFAS. [ABSTRACT FROM AUTHOR]

This article investigates the reduction of water pollution at four Norwegian paper mills from the early 1970s until 1997. Especially during the 1990s water pollution from the mills has converged at a relatively low level. This is due to changes in the production processes, implementation of a common environmental strategy and investment in research and development. Over the years environmental improvements have become an integrated part of the technological trajectory in this industry. A common understanding of the problems and possible solutions between government and industry is one reason why we can talk about a greener technological trajectory. One reason for this common understanding is that the regulation of environmental problems in the paper industry has been based on the principles in Norwegian industrial policy. Integration of these principles into a site-specific environmental policy meant that questions concerning the regional economy were judged against local water pollution problems. This means that the regulation of the paper industry has to be seen in both a historical, geographical and institutional context. Copyright © 2000 John Wiley & Sons, Ltd. and ERP Environment.

In the 2000s, several major education reforms have been implemented in Norway. The reform in the teacher education is heavily inspired by the Finnish model, with introduction of a new research-based content, with the aim of developing a new type of professional knowledge, as a basis for teachers' professional practice. Drawing on Maton's Legitimation Code Theory, this paper explores the tensions in the new Norwegian teacher education, between knowledge and ways of knowing, by examining students' practices, expressed in students' research and development papers in the new teacher education. The paper refutes a one-dimensional concept of experience-based practical knowledge in the teacher education and argues that professional knowledge is based on practices that are informed by specialized and theoretical knowledge.

Background: The trends in medical publishing are towards electronic versions and the use of the English language. The objective of this study was to compare general practitioners' ability to retain information when reading on paper versus on screen, and in their mother tongue versus in the English., Material and Methods: Randomized controlled trial of 114 Scandinavian general practitioners. They read a review article for 10 minutes either on paper/in English, on screen/in English, on paper/in their mother tongue, or on screen/in their mother tongue. Afterwards they completed a questionnaire with six open questions from the article. The main outcome measure was sum score on a scale from 0 (no correct answers) to 13 (all questions answered correctly)., Results: We found no difference between readers of paper and screen versions (median (interquartile range) 4 (2-6) vs. 4 (2-5), p = 0.97). Those who read their mother tongue scored significantly higher than those who read English (4 (3-6) vs. 3 (2-4), p = 0.01)., Interpretation: The medium (paper vs. screen) does not influence the ability of general practitioners to retain medical information. Doctors best retain medical information when reading it in their mother tongue.

Objectives: The study investigated cancer incidence among 23,718 male pulp and paper workers employed continuously for at least 1 year between 1920 and 1993 in Norway., Methods: The name, date of birth, personal identification number, dates of hire and termination for all employment periods, specific department, and job categories were registered for each worker. Six subcohorts were established (sulfite mill, sulfate mill, paper mill, maintenance department, administrative staff and other departments). Data on the cohort were linked with data in the Norwegian Cancer Register. The follow-up period for cancer incidence, date of death, or emigration was from 1953 through 1993., Results: An excess incidence of lung cancer was found among both short- and long-term employees [standardized incidence ratio (SIR) 1.5, 95% confidence interval (95% CI) 1.13-2.03 and SIR 1.2, 95% CI 1.09-1.34, respectively], especially for workers with the longest latency (SIR 1.3, 95% CI 1.08-1.44) and for sulfite mill workers (SIR 1.5, 95% CI 1.09-1.99). The risk for pleural mesothelioma was also increased (SIR 2.4, 95% CI 1.45-3.75), especially among maintenance workers. The results also showed an increased risk for malignant melanoma (SIR 1.3, 95% CI 1.04-1.60), an unexpected finding., Conclusions: Almost all the increased risk for lung cancer can be explained by a combination of smoking habits and asbestos use. although an effect of other work-related exposures (sulfur and chloride compounds, wood dust) cannot be excluded. Most of the cases of pleural mesothelioma occurred in departments where asbestos was used. There is no clear explanation for the excess of malignant melanoma, and the finding may be a chance occurrence.

A mechanistic nonlinear model of the wet end of paper machine 6 (PM6) at Norske Skog Saugbrugs, Norway has been developed, and used in an industrial MPC implementation. The MPC uses an infinite horizon criterion, successive linearization of the model, and estimation of states and parameters by an augmented Kalman filter. Variation in important quality variables and consistencies in the wet end have been reduced substantially, compared to the variation prior to the MPC implementation. The MPC also provides better efficiency through faster grade changes, control during sheet breaks and start ups, and better control during periods of poor measurements. From May 2002 of the MPC has been the preferred controller choice for the process operators at PM6.In this paper we also study if the model can be applied to PM4 at Norske Skog Saugbrugs, and PM3 at Norske Skog Skogn, Norway. No structural changes were necessary in order to fit the model to PM4 and PM3 data. The time spent on fitting the PM6 model to PM4 and PM3 is approximately 1% of the time spent on developing the original model. This should be a strong incentive for focusing on mechanistic modeling in industries were there are many similar production lines or units. [Copyright &y& Elsevier]

Background: It has been shown that implementation of electronic medical records (EMR) and withdrawal of the paper-based medical record is feasible, but represents a drastic change in the information environment of hospital physicians. Previous investigations have revealed considerable inter-hospital variations in EMR system use and user satisfaction. The aim of this study was to further explore changes of clinicians' work after the EMR system implementation process and how they experienced working in a paper-deprived information environment. Methods: Qualitative study based on 18 semi-structured interviews with physicians in two Norwegian hospitals. Results: Ten different but related characteristics of work within the EMR-based practice were identified; (1) there was closer clinical and administrative cooperation during the implementation processes; (2) there were greater benefits when everybody used the system; (3) systems supported freshmen better than experienced physicians; (4) the EMR was useful in regard to professional learning; (5) new users were given an introduction to the system by experienced; (6) younger clinicians reported different attitudes than senior clinicians, but this might be related to more than age and previous experience with computers; (7) the EMR made it easier to generate free-text notes, but this also created a potential for information overflow; (8) there is little or no support for mobile work; (9) instances of downtime are still experienced, and this influenced the attitude towards the system and (10) clinicians preferred EMR-only compared to combined paper and electronic systems. Conclusion: Despite the removal of paper-based records from clinical workflow (a change that hospital clinicians perceived as highly useful), many of the old routines remained unchanged, limiting the potential of the EMR system. Thus, there is a need to not only remove paper in the physical sense, but also to established routines to fully achieve the benefits of an EMR system. [ABSTRACT FROM AUTHOR]

This position paper highlights existing and emerging, prospective digital divides in Norwegian schools and asks whether we are now moving from traditional digital divides to digital inequality in our digitized society and schools. Despite very good technology density in Norwegian society and schools in general, there is the reason to pay attention to whether this situation creates new kinds of digital inequalities among already vulnerable pupil groups. Therefore, this position paper focuses on whether under the new Norwegian educational reform, the Knowledge Promotion, it is necessary to consider this issue from another angle because of e.g. the increased status of digital literacy and implementation of ICT-based (Information and Communication Technology) exams in the national curriculum. The position paper focuses on what kind of digital inequalities we see the profiles of and what issues the government has to consider to prevent these tendencies escalating. (Contains 1 figure.)

To level the playing field in employment, the Convention of the Rights of Persons with Disabilities require state parties to ensure the provision of reasonable accommodation in the workplace. The international literature shows that barriers to workplace accommodation (WA) provision arise during recruitment, hiring, and retention. In this paper, we complement prior research by examining how WA is represented in policy documents targeting disability and employment in Norway over the past 50 years. Bacchi's policy analysis framework inspired the analysis and discussion. The analysis reveals a pattern over three time periods: 1) segregation, including the state applying a holistic approach and responsibility for WA; 2) integration, including an activation approach stimulating employer responsibility; and 3) inclusion, including holding employers more responsible. The results lead us to ask whether too much financial responsibility and work-inclusion efforts to increase employment among disabled people are currently left up to employers.

Human rights education (HRE) has been recognised in international educational discourses as a sustainable practice to develop active citizenship and protect human dignity. However, such education has not been fully explored in a broader political context. In addition to contributing to empowering citizens to resist human rights violations, HRE plays several roles in society, contributing to both national identity and international image-building. The article explores possible relations between national identity construction, foreign policy and HRE in Norway through the following research question: "What interplay occurs between Norwegian foreign policy and national identity in relation to human rights, and, within this context, what is the role of HRE?" The article presents a qualitative analysis of Norwegian policy documents and reports, arguing that HRE is a component of Norwegian national identity as well as political currency in foreign relations.

Analyses of policy documents and interviews with three Norwegian politicians revealed differences in how school leaders were described, positioned and ascribed responsibility in Norwegian education policy between 1990 and 2017. While how politicians positioned school leaders changed substantially during the period, a stable trait was vague descriptions of school leaders' responsibility. In 1990, school leaders were envisioned in a managerial position, above teachers, as employers. A more recent White Paper, from 2017, positioned school leaders closer to the teaching profession. The interviews showed that after the PISA-shock in 2001, politicians united across party lines in a 'new regime of understanding', downplaying traditional conflicts between Norwegian politicians. While Parliamentary politicians rhetorically disagreed, there was, underneath the policy discourse, a growing realpolitik consensus in questions of education policy. The study investigates policy descriptions of school leaders after 1990, when Management by Objectives was introduced in education. To position Norway in the international policy context, we draw on Stephen Ball's concepts fabrication, managerialism, magical solutions and neoliberal performativity. Three periods, with simultaneously appearing residual and emerging tendencies were identified. In conclusion, we question an apparent lack of ambitions for school leadership in Norwegian education policy. The article contributes with new insights into education policy fluctations.

Objectives: Nordic register data are not collected for research purposes, and various dimensions of working conditions are typically missing in register-based research. One way to address the issue of missing information on the work environment in register data is to utilize a job exposure matrix (JEM). The purpose of this paper is to document and provide access to a Mechanical Job Exposure Matrix (JEM) and a validated Occupational Mechanical Job Exposure Index based on the constructed JEM, allowing researchers to utilize the index in register-based research. The JEM and the Occupational Mechanical Job Exposure Index were created using data from five nationwide Surveys of Living Conditions on work environment conducted in Norway in 2006, 2009, 2013, 2016, and 2019, encompassing a total of 43,977 respondents. The index can be merged to register data using occupational codes (STYRK-98) and gender, which is information collected by the registries. The ultimate aim of constructing the index was to create a comprehensive measure of mechanical job exposures for use in future analyses of Norwegian register data. Data description: This paper provides the scripts documenting the construction of the Mechanical Job Exposure Matrix (JEM) and the Occupational Mechanical Job Exposure Index, as well as a data file including the matrix and the index. A script for merging the matrix and index to register data is also provided. [ABSTRACT FROM AUTHOR]

The main purpose of this article is to explore and develop a basic understanding of a new formulation of children's learning within ECEC policies in Norway. In the Nordic Countries, one question of importance is the shift in ECEC policy from a social-pedagogical approach and a holistic perspective on children's learning towards a heavier emphasis on school readiness, mathematics, and linguistic skills. And it is this latter approach which is our topic here. The research question is as follows: What transformations can be identified in learning discourses in the Norwegian government's White papers? Analysing political reports will help us identify discourses, including the power and resistance of the ECEC professionals. For this purpose, Fairclough's three-dimensional analysis model is an appropriate way to analyse dynamic processes of recontextualization and reconceptualization. His analysis includes three levels: social structure, social practices and social events, with the aim being to discover how the existing order of discourse is being reproduced or reconstructed. Further, the concept of interdiscursivity describes how texts draw on previous and existing discourses. The article identifies movements and complexity both in policies and among professionals. The learning discourses are strongly influenced by New Public Management in the way of individualization, assessment and accountability. There are signs of silence and acceptance, but resistance and countermovements are also present in the field of ECEC. [ABSTRACT FROM AUTHOR]

In this article we study three Norwegian reports concerning the environmental problems connected to use of natural resources and production of waste. The reports are responding to political initiatives in White Paper 58 (1996–97) and White Paper 8 (1999–2000). The reports describe, analyse and give reasons for various resolution strategies with regard to excessive consumption of virgin natural resources, inefficient economic processes and irresponsible waste management. The purpose of this article is threefold. First, we present a theoretical framework that enables an integrated analysis of economic problems. We have termed the theoretical context for our analysis circulation economics. Second, we illustrate the complexity of the problems through a discussion of the three different reports concerning waste management. Third, in the context of circulation economics the different reports elucidate various aspects of the phenomenon area and the new perspective can be used to synthesize the partial findings. In addition to this, we suggest where further work has to be done in the future. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment. [ABSTRACT FROM AUTHOR]

Background: In the section for general practice at the University of Bergen, Norway, we want to emphasise learning more than control in our work with students. As a step in this direction we invited students to come up with proposals for exam papers, papers that usually include six to nine multiple steps for clinical reasoning. We guaranteed that one out of three proposals would be included as a paper in the written examination, possibly slightly modified. This article is an evaluation of the consequences of letting medical students set some of their own exam papers., Material and Methods: The process was evaluated using 1) grades given, 2) students' assessment of whether this mode of setting papers influenced their exam preparations, and 3) students' free-text comments on the process., Results: 57 out of 64 students (89%) took part in the evaluation. All knew that their fellow students had set one of the exam papers, but only 34 (60%) reported that this knowledge had changed the way they prepared for the exam. The mean grade was 9.9 (range 5-12, on a scale from 1 to 12, 6 being the lowest pass grade) for the paper set by students, and 9.5 (range 5-11) for all papers combined. Mean difference in score was 0.32 (95% confidence interval 0.08-0.64). Students' free-text comments showed that they specifically prepared for the three known paper topics. They drew comfort from knowing at least one of the papers set, and the student-set papers were found relevant for general practice., Interpretation: Letting medical students set one of the exam papers makes them feel more confident. Student-set papers were seen as relevant for clinical practice. The control function of the exam seemed to have been preserved.

Reliable sea-level observations in coastal regions are needed to assess the impact of sea level on coastal communities and ecosystems. This paper evaluates the ability of in-situ and remote sensing instruments to monitor and help explain the mass component of sea level along the coast of Norway. The general agreement between three different GRACE/GRACE-FO mascon solutions and a combination of satellite altimetry and hydrography gives us confidence to explore the mass component of sea level in coastal areas on intra-annual timescales. At first, the estimates reveal a large spatial-scale coherence of the sea-level mass component on the shelf, which agrees with Ekman theory. Then, they suggest a link between the mass component of sea level and the along-slope wind stress integrated along the eastern boundary of the North Atlantic, which agrees with the theory of poleward propagating coastal trapped waves. These results highlight the potential of the sea-level mass component from GRACE and GRACE-FO, satellite altimetry and the hydrographic stations over the Norwegian shelf. Moreover, they indicate that GRACE and GRACE-FO can be used to monitor and understand the intra-annual variability of the mass component of sea level in the coastal ocean, especially where in-situ measurements are sparse or absent.
