- Abstract
Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the first to assess consistency of results by agency. We find results vary by agent, but consistent with Flynn effects, gains are larger in math than reading, except for the most recent period. Non-whites progress at a faster pace. Socio-economically disadvantaged white, black, and Hispanic students make greater progress when tested in elementary school, but that advantage attenuates and reverses itself as students age. We discuss potential moderators.

- Abstract
The feedback between vocational education and training (VET) and the labour market can provide important input for the review and renewal of qualifications. A feedback loop that is based on learning outcomes helps provide deeper insights into what is required on the labour market, what is offered in training provisions and assessed at the end of a learning programme. The aim of this study is to contribute to strengthening the quality and relevance of qualifications and completing the feedback loop between education and the labour market. It examines methods of collecting data on the match/mismatch between qualifications and labour market requirements, including analysis of how achieved learning outcomes are applied and perceived in the labour market (for example methods of collecting the experience of employers with holders of these qualifications). This report addresses the following two questions: (1) which data already exist in the countries, providing insight into the relevance of qualifications to employees, employers and other labour market stakeholders?; and (2) how can survey methodology be designed to systematically capture the experiences and appreciations of employers as regards the content and profile of qualifications? To what extent, based on limited testing, can scalability of the methodology be achieved?

- Abstract
Individual teachers, administrators, and parents made tremendous efforts to continue educating the Commonwealth's children between March and June of this year. But no amount of dedicated individual effort could have overcome fundamental challenges: weak guidance to districts from the Department of Elementary and Secondary Education (DESE) against a backdrop of deficient knowledge and sophistication statewide with regard to virtual learning. Digital education has been empirically proven to be most successful when schools prepare and follow best distance learning practices. However, the Commonwealth lacks even the minimum technological infrastructure for virtual learning, as exemplified by districts scrambling to obtain electronic devices and internet connections during the school closure. It is encouraging that Governor Baker and the DESE have described a fall 2020 return to brick-and-mortar schooling--with appropriate health measures to maximize safety--as a significant priority. The present challenge is how to implement this much-needed return to school, optimally balancing the importance of in-person schooling with the countervailing importance of protecting against the virus. The following paper contributes important insights, based upon careful review of other countries that have already successfully reopened their schools. [Foreword written by David S. Clancy and Dr. John G. Flores.]

- Abstract
The European Union is likely the most far-developed cross-border public space for higher education. The European Higher Education Area (EHEA) and the European Research Area (ERA) both span an even larger number of countries including associate and partner countries of the EU. Based on shared European values, such as academic freedom, cross-border cooperation, and mobility, these policy frameworks have been developed in Europe over the last decades and with much success. HE systems in this area are thus well-positioned to benefit from cross-border mobility and collaboration but may at the same time face a certain loss of control over HE, for instance with respect to access due to the cross-border flows of students. This seems to make them vulnerable to populist tendencies and neo-nationalist politics seeking to inhibit the free movement of students, scholars, and data. Such tendencies have never been completely absent on the "old continent" but resurged over the uneven outcomes of globalization, the effects of the global financial and consequent Euro crisis, and the refugee crisis. Meanwhile, the impact of the coronavirus crisis is still by and large unknown. Populist tendencies seem now to be turning against the EU, with its freedom of movement for persons (i.e. open borders) as one of its cornerstones and are therefore of concern for the HE sector. Countries such as the UK, Switzerland, Denmark, and the Netherlands have a different position in the European landscape but are all struggling with the complexity of combining the virtues of an open system with constrained national sovereignty. Sovereignty is required in terms of steering capacity in order to balance access, cost, and quality, i.e. the well-known "higher education trilemma." In open systems this is challenged by the "globalization trilemma", which states that countries cannot have national sovereignty, (hyper)globalization and democracy at the same time. How are the EU, its Member States, and the HE sector responding? Will the Union stay united (i.e. Brexit)? Are the legal competencies of the EU in HE strong enough? What about the many European university associations, leagues, and networks? And what do the millions of (former) Erasmus students have to say?

Stark Education Partnership
- Abstract
This white paper presents a selection of model schools who all have, to some degree, fostered deeper learning. Schools were selected by internet search, or through references in "deeper learning" reports and documents. It should be noted that information in these reviews is based on information from school web-sites, in some cases the web sites of state education agencies, media reports and ratings, such as those published by "US News and World Report" or "Newsweek." It is hoped that this paper will serve as a resource directory of sorts, giving interested parties the opportunity to read more widely about these schools, consult the referenced documents, or to contact the schools directly.

- Abstract
This research paper is the fifth in a series produced as part of the Cedefop project The changing nature and role of VET (2016-18). Based on comparative analysis of labour force survey data from 2014, the report analyses the vocational effect on labour market and education outcomes, asking whether any advantages conferred by vocational qualifications in early career would be offset by disadvantages later in life. The report explores the functioning of the safety net and the diversion effects across countries, demonstrating how these vary considerably with the specific institutional structure of schooling and work-based training. The results indicate that VET graduates are potentially sacrificing the longer-term gains associated with further education in favour of short-term benefits. [This research was carried out by a consortium led by 3s Unternehmensberatung GmbH and including the Danish Technological Institute, the Institute of Employment Research (University of Warwick), the Institute of International and Social Studies (Tallinn University) and Fondazione Giacomo Brodolini.

- Abstract
In a highly competitive global landscape, occupations are transformed, new jobs are created and the skills needed for the labour market are constantly changing. European countries are looking at redefining VET [vocational education and training] to respond promptly to such challenges and take advantage of the opportunities ahead. They are reforming to modernise their VET systems and strengthen the relevance of their national qualifications in an international context. This publication explores national responses to globalisation in 15 countries and five economic sectors. It aims to understand how European and international initiatives help VET renewal across Europe. It shows how countries' reactions are embedded in their national traditions but also depend on their interactions with European, sectoral and multinational players that provide training and award qualifications.

- Abstract
In many developed countries, children now begin their formal schooling at an older age. However, a growing body of empirical studies provides little evidence that such schooling delays improve educational and economic outcomes. This study presents new evidence on whether school starting age influences student outcomes by relying on linked Danish survey and register data that include several distinct, widely used, and validated measures of mental health that are reported out-of-school among similarly aged children. We estimate the causal effects of delayed school enrollment using a "fuzzy" regression-discontinuity design based on exact dates of birth and the fact that, in Denmark, children typically enroll in school during the calendar year in which they turn six. We find that a one-year delay in the start of school dramatically reduces inattention/hyperactivity at age 7 (effect size = -0.7), a measure of self regulation with strong negative links to student achievement. We also find that this large and targeted effect persists at age 11. However, the estimated effects of school starting age on other mental-health constructs, which have weaker links to subsequent student achievement, are smaller and less persistent.

- Abstract
This study addresses qualifications at level 5 of the European qualifications framework (EQF) in 15 countries (Belgium (Flanders), the Czech Republic, Denmark, Estonia, Ireland, France, Croatia, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Austria, Portugal, the United Kingdom (EWNI and Scotland) that had linked their national qualification levels to the EQF by June 2012. EQF level 5 qualifications play an important role in providing access to employment and career advancement as well as enabling further learning and progression to higher education. This double function makes them attractive to learners and employers. Although the extent to which countries use qualifications at EQF level 5 differs, their importance is growing in all countries investigated for several reasons. First, they are developed as response to increased needs for advanced technical and/or management skills. Second, they seem to be especially attractive to students with VET background and those already in employment. They also contribute to lifelong learning by being accessible and attractive for adults and non-traditional learners. The following are appended: (1) List of working definitions; (2) List of interviewees; (3) Available data on EQF level 5 qualifications; (4) Key purposes and functions of qualifications; (5) Further material on learning outcome descriptions of qualifications; and (6) Duration and mode of delivery. A bibliography is also included. [The research was carried out by Panteia in consortium with 3S under Cedefop service contract AO/ECVL/JBSPEV/Qualifications_EQF_level_5/001/12.]

- Abstract
Differences in teacher quality are commonly cited as a key determinant of the huge international student performance gaps. However, convincing evidence on this relationship is still lacking, in part because it is unclear how to measure teacher quality consistently across countries. We use unique international assessment data to investigate the role of teacher cognitive skills as one main dimension of teacher quality in explaining student outcomes. Our main identification strategy exploits exogenous variation in teacher cognitive skills attributable to international differences in relative wages of nonteacher public sector employees. Using student-level test score data, we find that teacher cognitive skills are an important determinant of international differences in student performance. Results are supported by fixed-effects estimation that uses within-country between-subject variation in teacher skills.

- Abstract
This report analyses how learning supports labour market transitions and career changes of adult workers across five countries (Denmark, Germany, Spain, France and Italy). To make the most of career and labour market opportunities, individuals have to rely on their own resources and their agency but also know how to navigate the institutional context. To make successful labour market transitions, individuals need to have a sense of direction, they need to learn about opportunities, and they need to learn skills. Education and training has a special role in supporting adult workers in their careers, providing them with the competences, qualifications and, in some cases, with the self-confidence needed for successful transition. Guidance services tailored to individual needs can help individuals find appropriate career trajectories in their search for suitable job opportunities, and can foster relational, emotional, cognitive and practical learning.

- Abstract
Improvements in workforce skills are essential for European countries to attain higher economic growth and to compete effectively on product markets. Literature indicates a positive relationship between levels of education and productivity growth. This report builds on and expands this body of research in two ways: (1) It investigates the differential impact of various skill types--higher (academic), upper-intermediate vocational, lower-intermediate vocational, lower-intermediate general, and low--on labour productivity; and (2) It accounts for the stock of uncertified skills (i.e. those built through training). The analysis is carried out in six European Union Member States--Denmark, Germany, France, the Netherlands, Sweden, and the United Kingdom--representing different modes of vocational education and training (VET) and those for which data were available. The analysis suggests that general and vocational skills complement each other and that the effect of certified skills on productivity is stronger when certified skills are reinforced by training. This study underlines that learning in the workplace, both in initial and continuing VET, makes a fundamental contribution to productivity, and comes to support policy efforts to develop apprenticeship and adult learning. The following annex is included: (1) Overview of research methods used in the study.

- Abstract
A strong VET system is increasingly seen as essential to overcoming the current economic crisis in Europe. VET is seen as a powerful tool to assist in balancing labour market inefficiencies, increasing youth employment possibilities, and reducing skills mismatch. Its inherent flexibility and closeness to the labour market place VET in a good position to contribute to a faster economic recovery and long-term sustainable development. However, crucial for this role is continuous and systematic VET renewal that assures its relevance for the labour market. This publication explores 15 European national approaches to feedback mechanisms between VET and the labour market. It illustrates the diversity of solutions currently applied across Europe and how they are embedded in national traditions and education philosophy. The study asks three fundamental questions: how inclusive are national mechanisms for feedback between the VET system and the labour market; how responsive are existing mechanisms; and how transparent? Three annexes provide: (1) Case Studies; (2) List of interviewees; and (3) List of experts responsible for the country overviews. Bibliography and references are included.

16. Professional Identity as Learning Processes in Life Histories. Roskilde University Life History Project Paper.

- Abstract
The question of how to theorize the subjective side of work within a life history perspective was explored. The findings of a study on engineers' subjective recognition of their lives, their education and jobs, and their life perspectives and the findings of a study of continuing education within a number of white-collar and semiprofessional work domains were cited as supporting the existence of a close interrelationship between professional learning and personal development. It was argued that, within the theory of modernization, professionalization appears as a moment in rationalization of society. The ongoing professionalization within public human services in the Nordic countries and elsewhere was used to illustrate how professional learning leads to personal development. The evolution of various human service occupations from "craft-like" occupations to professions was shown to parallel the process of development of a new identity during which individuals who had viewed themselves as individuals performing labor for a wage began viewing themselves as individuals in a career or "position." The concept of identity was discussed in relation to Ute Volmerg's conception of basic socialization as a production of identity, Erikson's cultural psychology theory, and Lorenzer's theory of socialization, as well as in relation to the concepts of contradiction and ambivalence.

- Abstract
The Life History Project at Denmark's Roskilde University is a 5-year research project that was initiated in 1998 to examine learning and participation in adult and continuing education from a life history perspective. The project was designed to build on a broad range of qualitative interview studies and case studies into learning processes. The research methodology designed for the project was grounded in the critical theory tradition and in the following premises: (1) the need to adopt a "holistic" approach that takes the learner's perspective; (2) the notion of experience and the specificity of the learning subject; (3) the need to move beyond conventional hermeneutics to "in-depth hermeneutics," which involves looking for meanings and implications going beyond the knowledge or intent of the acting, knowing, or speaking subject; and (4) the notion that a learning subject is a historical product of modernity and the need to relate it to a dynamic-utopian concept of a learning individual.

- Abstract
"Can You Hear Me? The Right of Young Children to Participate in Decisions Affecting Them" emphasises that participation enhances children's self-esteem and confidence, promotes their overall capacities, produces better outcomes, strengthens understanding of and commitment to democratic processes and protects children more effectively. Participation provides the opportunity for developing a sense of autonomy, independence, heightened social competence and resilience. The benefits are therefore significant, and adults with both direct and indirect responsibility for children need to acquire a greater humility in recognising that they have a great deal to learn from children. But the case for listening to young children goes beyond the beneficial outcomes. It is also a matter of social injustice and human rights. All people, however young, are entitled to be participants in their own lives, to influence what happens to them, to be involved in creating their own environments, to exercise choices and to have their views respected and valued.

Roskilde Univ. Center (Denmark). and Anderson, Linda
- Abstract
The relationship between life history, gender, and the discourse of modernization was examined from the perspective of a researcher with extensive experience performing evaluations about modernization within human services in Denmark. Three stories about site-based management in two human service institutionsa youth center and a boarding school for autistic childrenwere presented to illuminate fragments of the complex condition that modernization represents. One story, which was told by a female superintendent, reflects feelings of skepticism and professional pride and discusses modernization in terms of development. A second story, which was told by a male superintendent, stresses the challenges and criticism encountered during modernization. In analyzing the stories, the author explored the following themes: (1) the discourse of modernization; (2) pre-existing or interpretive narratives; (3) the notion of the dialectical, liberated, and dispersed subject and the various theoretical forms in which life histories emerge; (4) the concepts of subject and surface and their relationship to the discourse of life history and modernization; (5) fluent and fixed icons of life history; (6) lost virginity and floating space as images of modernization; and (7) rituals of passage, storytelling, imagination, and the researcher's voice.

- Abstract
A study investigated the effectiveness of tandem second language learning using electronic mail (e-mail). Tandem language learning refers to a partnership between two learners, each learning the other's native language. The underlying principles of reciprocity and learner autonomy are explored, use of asynchronous communication between individuals for language learning is discussed, and theory on communicative language learning and the role of writing in language learning is examined, and the study is presented. Subjects were seven dyads of native English- and native Spanish-speaking adults of varied second-language proficiency levels, located in Ireland, Denmark, and Spain. Data were drawn from analysis of e-mail messages and a survey of participants. Analysis focuses on choice of language, type of language used, nature of cultural exchange, style and quality of peer feedback, development of language usage awareness, communication strategies, and students' comments and attitudes. Conclusions and areas for further research are discussed. Contains 53 references. (MSE)

This paper is the last in a series of 14 detailing the procedures involved in setting up an interdisciplinary project that explores the similarities and dissimilarities in the response to literature in readers from different countries. It marks the end of the preparatory work for the "Folktale-project." The first section is an overview of the folktale project from its inception to the main data collection. The second section is a presentation of the basic assumptions that had to be set up as indisputable points, simply in order to carry out the study in the time allotted and with the resources available--over a decade. It reviews reasons behind the choice of literary material, the length of that material, the cultural imprint of that material, and the languages in which that material appeared. The third section briefly cites the procedures in the final data collection as well as the number of questionnaires completed. Contains an appendix of research material. (TB)

- Abstract
This report summarizes six case studies on different aspects of the issue of evaluating investing in continuing vocational training (CVT). Part 1 (chapters 1-2) contains "Conceptual Introduction" (Jean-Marie Luttringer), which explores practical problems in considering training expenses as an investment, and "Methodological Introduction" (Alan Barrett), which discusses the merits of using qualitative and quantitative research methods in evaluating CVT investments. Part 2 (chapters 3-8) describes and analyzes continuing training schemes in six European Member States: "The Evaluation of CVT in Enterprises in Styria in Austria" (Stefan Lorenzoni, Dieter Mandl) investigates whether certain goals of CVT were achieved; "The Importance of CVT to Enterprises: A Discussion of the Agricultural Foodstuffs Sector in Denmark" (John Houman Sorenson) seeks to understand why CVT is not being used; "Accounting for Enterprise Investment in CVT in France" (J-M Luttringer, N. Pasco) discusses difficulties associated with evaluating CVT investments; "Innovative Models for Financing CVT in Germany" (Uwe Grunewald, Dick Moraal) studies four innovative models of CVT provision; "Measuring the Impact of CVT in Irish Companies" (Alan Barrett, Philip O'Connell) explores whether training and productivity growth are positively related across a sample of firms. "CVT Activity within the Packaging Sector in Italy" (Francesco Garibaldo) provides insights into how CVT can be used to cope with challenges faced by a sector. Part 3 contains two chapters: "Methodological Discussion, Conclusions, and Further Work" (Alan Barrett), which reviews each report individually before drawing general conclusions regarding methodology and "Policy Discussion, Conclusions, and Further Work" (Jean-Marie Luttringer), which examines seven problems in the assessment of training investment. Appendixes provide background to CVT in the six countries. (YLB)

A sustainable industrial future involves the exploitation of renewable resources to obtain a wide diversity of products and energy and the decrease of waste generation. Primary sludge (PS) from pulp and paper mills is a lignocellulosic residue mainly consisting of cellulose and hemicelluloses that can be converted to bioethanol. In the present work, bioethanol was produced from untreated PS by simultaneous saccharification and fermentation (SSF). Studies were carried out on initial solid concentration, yeast inoculum percentage, cellulolytic enzyme dosage, and co-application of two enzyme complexes (cellulolytic NS 22192 and xylanolytic Cellic
® HTec2, Bagsværd, Denmark). Increasing solid content up to 22% improved ethanol concentration (59.1 g L−1 ), productivity (1.97 g L−1 h−1 ), and yield (86.3%); however, at the maximum solid concentration (28%), both yield and productivity decreased. At the highest solid concentration, a decrease of 33% in the cellulolytic enzyme dosage was observed (compared to reference enzyme loadings). The co-application of the two enzyme complexes had a positive effect on PS conversion efficiency. When a preliminary scale-up strategy was implemented from 50 mL to 2.5 L at 22% solids concentration, similar results were obtained despite the initial mixing difficulties of the heterogeneous system.

- Abstract
Two studies are reported that investigated the views of Danish secondary school students studying German. The first, an observational study, revealed that the vast majority of questions Danish students posed during German lessons concerned grammar and vocabulary. The second study was a questionnaire that revealed that the Danish students were studying German for largely practical reasons. It is concluded that Danish students want more information on today's Germany, rather than its historical past or its culture, and that German instruction in Denmark needs to be more connected with the present reality of the students.

- Abstract
Two articles highlight different issues on foreign language learning and instruction in Denmark. The first article describes a research project at Roskilde University Center that focuses on group organized and self managed foreign language acquisition. The idea for the project came about as a result of concern over problems related to foreign language instruction, such as student motivation, cuts in funding, and especially the idea that foreign language instruction is too "teacher directed." Five students, between ages 20 and 40 and of various backgrounds, participated in the project. Emphasis was on student management of language learning (e.g., students led classroom discussion while teacher acted as participant). Students read certain materials, recorded their discussion of the materials, and analyzed the recorded discussion for "correctness." Research notes and the texts used for discussion are appended. The second article looks at the status and function of foreign languages in secondary schools. The thesis for the article is the "foreign language crisis," which refers to issues such as a reduction in funding for foreign language education, and the technical and pedagogic difficulties faced by foreign languages in secondary schools. The article discusses where language instruction fits into educational planning, what the central problems are with foreign language instruction, and what resolutions there are to the foreign language crisis in secondary schools.

- Abstract
Objectives: Studies in traditional paper mills have indicated an excess cancer risk, and mutagenic compounds have been identified in the industry. No studies have reported on risk of cancer in paper recycling. Therefore the cancer incidence in Danish paper recycling mills was investigated., Methods: 5377 employees in five paper recycling plants were included in a historical cohort study. The workers had been employed in paper recycling in 1965-90, and the cohort was followed up until 31 December 1993. The expected number of cancer cases was calculated from national rates., Results: There was significantly more pharyngeal cancer among male workers (seven observed (standardised incidence ratio (SIR) 3.33, 95% confidence interval (95% CI) 1.34 to 6.87)). There was slightly more lung cancer among male workers in production (39 observed, SIR 1.21, 95% CI 0.86 to 1.65). Risk of Hodgkin's disease was doubled in male production worker (four observed, SIR 1.90, 95% CI 0.51 to 4.85)., Conclusions: The increased risk of pharyngeal cancer found in this study is interesting but may be influenced by confounders such as smoking and alcohol intake. This study also indicates an excess risk of Hodgkin's disease, which is in accordance with some studies in the traditional paper mills. As this is the first report on risk of cancer in paper recycling, further studies are needed.

- Abstract
The purpose of this study is to explore undocumented immigrant women's experiences of, as well as their access to, maternity care services during pregnancy in Denmark. Recruiting through the two branches of a non-governmental organization (NGO)-driven health clinic in Denmark, we conducted 21 semi-structured interviews with undocumented immigrant women in Denmark from January 2018 to January 2019. The undocumented immigrant women experienced barriers such as fear of deportation, concerns about payment for services, and uncertainties about rules for access. Many of them described depending on NGO-driven initiatives to access maternity care services and found these as providing a safe environment for care. Our findings contribute insights towards understanding the health behavior of undocumented immigrant women and highlight the need for inclusive care to safeguard the health of the women and their children.

- Abstract
Interferon (IFN)-γ release assays (IGRAs) are probably the most accurate tests for the detection of latent Mycobacterium tuberculosis infection, but IGRAs are labour intensive and the transport of samples over longer distances is difficult. IFN-γ-induced protein (IP)-10 is expressed at 100-fold higher levels than IFN-γ, and IP-10 release assays have comparable performance to IGRAs. The aim of this study was to explore the diagnostic potential of a novel IP-10 release assay based on dried plasma spots (DPS). The presence of IP-10 and IFN-γ was determined in plasma and in DPS by ELISA. Diagnostic algorithms for plasma and DPS tests for IP-10 were developed on a training cohort comprising 60 tuberculosis (TB) patients and 59 healthy controls. Diagnostic accuracy was assessed in a validation cohort comprising 78 TB patients and 98 healthy controls. Plasma was measured in Spain and DPS samples were sent to Denmark using the conventional postal service for analysis. IP-10 was readily detectable in both plasma and DPS, and correlation was excellent (r(2) = 0.95). QuantiFERON-TB Gold In-Tube (QFT-TB) and IP-10 in DPS and plasma rendered comparable sensitivity (78%, 82% and 84%, respectively), specificity (100%, 97% and 97%, respectively) and indeterminate rates (p>0.55). The DPS-based IP-10 test has comparable diagnostic accuracy to the QFT-TB and samples can be sent via conventional mail over long distances for analysis without affecting the results.

- Abstract
Background: A large number of nondigitized electrocardiograph (ECG) strips are routinely collected in larger cohort studies such as the ADDITION study (Anglo-Danish-Dutch Study of Intensive Treatment in People with Screen-Detected Diabetes in Primary Care). These ECG strips are routinely read manually but may contain overlooked information revealing cardiac autonomic dysfunction. The aim of this study was to investigate whether clinical information may be lost using manual R wave to R wave (RR) interval measurements in the calculation of heart rate variability (HRV) in patients with type 2 diabetes mellitus (T2DM)., Method: From the Danish part of the ADDITION study, we randomly selected 120 T2DM patients at baseline of the ADDITION study. Analysis of the ECG strips was performed using two different methods: (1) by experienced technicians using rulers and (2) by experienced technicians using a high-resolution computer-assisted method. Calculation of heart rate and time domain HRV [standard deviation of normal-to-normal RR intervals (SDNN) and root mean square of successive differences (RMSSD)] were performed with the same software., Results: When comparing results from the two methods, the following values of Pearson's r are obtained: 0.98 for heart rate, 0.76 for SDNN, and 0.68 for RMSSD. These results indicate that heart rate and HRV measurements by the computer-assisted and manually based methods correlate. However, Bland-Altman plots and Pitman's test of difference in variance revealed poor agreements (p < .01) for both HRV measurements (SDNN and RMSSD); only heart rate showed substantiated agreement (p = .54) between the two methods. Low HRV was statistically significantly associated to high heart rate, systolic blood pressure, and diastolic blood pressure in these screen-detected T2DM patients., Conclusions: Paper ECG strips may contain overlooked clinical information on the status of autonomic function in patients with T2DM. In our study, manual measurements of RR intervals were inferior to the computer-assisted method. Based on this study, we recommend cautiousness in the clinical use and interpretation of HRV based on manual or low resolution measurements of RR intervals from ECG strips. High resolution measurements of RR intervals reveal significant associations between low HRV and high heart rate, systolic blood pressure, and diastolic blood pressure among patients with screen-detected T2DM. It is feasible to use a computer-assisted method to determine RR intervals in patients with T2DM., (© 2012 Diabetes Technology Society.)

- Abstract
History has been kind to Christian Bohr (1855-1911). His name is attached eponymously to three different areas of respiratory physiology. The first is the Bohr dead space, which refers to the portion of the tidal volume that does not undergo gas exchange. The second is the increase in oxygen affinity of hemoglobin caused by the addition of carbon dioxide to the blood. This is known as the Bohr effect and is a very important feature of gas exchange, both in the lung and in peripheral tissues. Both of these contributions by Bohr are familiar to most students. Bohr's third contribution refers to the calculation of the changes in the Po
2 of blood as oxygen is loaded in the pulmonary capillary, the so-called Bohr integration. This contribution is less well known now, partly because of the advent of digital computing, but it was important in its day. The analysis is challenging because the very nonlinear shape of the oxygen dissociation curve means that the Po2 difference between the alveolar gas and the capillary blood, which is the driving pressure for diffusion, changes in a complicated way. All three papers are in German, and two of them are long and tedious to read. English translations are available, but few people read the papers, despite the fact that the first two articles are very frequently cited. In the present article, Bohr's contributions are reviewed, and some parts of the articles that are particularly difficult to understand are clarified.- Published

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.

Due to the coating materials used, historic raincoats are vulnerable to degradation and rarely survive long periods of time. The investigated raincoat dating from 1943 is no exception—the coating is unusually stiff and flaking off in areas around folds and cracks. Study into its material composition can contribute to important knowledge of the availability of materials for waterproof clothing during the time of the German occupation of Denmark (1940–1945) when the usual materials for raincoats, cotton fabric and rubber, were in short supply. Optical microscopy and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) identified the fabric to consist of rayon staple fibres and paper yarn, and the coating to be based on cellulose nitrate (CN) lacquer and an unknown plasticiser. Though the results are atypical for a raincoat, they are in good accordance with the raw materials available in Denmark in 1943. Analysis by matrix-assisted laser desorption-ionisation mass spectrometry (MALDI-MS), and
1 H and13 C nuclear magnetic resonance spectroscopy (NMR), identified the plasticiser as poly(1,3-butylene) adipate. Powder X-ray diffraction (PXRD) moreover identified the pigment as titanium white of the anatase form. By historical discussion, this study argues that IG Farben is the likely producer of poly(1,3-butylene) adipate, even though the first known marketing of the plasticiser is from 1986 where the Swiss firm Ciba-Geigy introduced poly(1,3-butylene) adipate as a plasticiser for PVC cling films under the tradename Reoplex® 346. The results give an interesting insight into the use of substitution products during WWII and provide new information on polymer science of the time. [ABSTRACT FROM AUTHOR]- Published

50. Critical CALL: Proceedings of the 2015 EUROCALL Conference (22nd, Padova, Italy, August 26-29, 2015)

- Abstract
The 22nd EUROCALL conference was held at the University of Padova from the 26th to the 29th of August 2015, the first time that EUROCALL has been held in Italy. The event was organized in collaboration with the University Language Centre and the support of the Department of Political Science, Law and International Studies. Over 300 delegates travelled from over 37 different countries to attend. The theme of the conference this year was Critical CALL, drawing inspiration from the work carried out in the broader field of Critical Applied Linguistics. The term "critical" has many possible interpretations, and as Pennycook (2001) outlines, has many concerns. It was from these that the conference theme was decided, in particular the notion that assumptions that lie at the basis of a field's praxis should be questioned, ideas that have become "naturalized" and are not called into question. Another concern of Critical Applied Linguistics is the relationship between the macro and the micro, an engagement with issues of power and inequality and an understanding of how classrooms and conversations are related to broader social, cultural and political relations. Over 200 presentations were delivered in 68 different sessions, both in English and Italian, on topics related specifically to the theme and also more general CALL topics. 94 of these were submitted as extended papers and appear in this volume of proceedings. An author index is included. (Individual papers contain references.)
