Fulfilling the promise: do MOOCs reach the educationally underserved?

When massive open online courses (MOOCs) began, they held the promise of bringing high-quality, college-level courses from leading academic institutions to people who otherwise would not have access to that type of content. In the ensuing years, it has become clear that the majority of MOOC students are not underserved in terms of educational opportunities; the typical MOOC learner already has a college degree. However, this does not mean that MOOCs are failing to fulfill the promise of democratization. Among the millions of learners who have taken Coursera MOOCs, there are some for whom this is their only way to access a rigorous, college-level course. In this analysis, we present descriptions of three learner populations for whom a MOOC offered an opportunity that they could not have had otherwise. These groups are (1) young people under the age of 18, (2) older adults over 65, and (3) people who reported that they did not have access to higher education opportunities. We compare the demographic characteristics, course attitudes and intentions, as well as qualitative learner feedback from each of these groups to the Coursera student body as a whole to understand the unique benefits that MOOCs bring to each of these underserved groups. We used data collected from 13 MOOCs offered by Duke University in the Fall 2014 semester. The data used in this analysis come from pre-course surveys administered to everyone who registered for a Duke MOOC. Finally, we illustrate our findings with qualitative data from open-ended survey questions. Our analysis shows that each group has a unique profile in terms of self-reported course experiences. Contrary to claims that MOOCs are not fulfilling the promise of democratization of education, learners have benefited by gaining access to content and learning experiences they otherwise would not have had.

New developments in ESP teaching and learning research

In this collective volume, we seek to bridge gaps between research and practice in the teaching and learning of English for Specific Purposes (ESP) with a set of strong research-based contributions drawing on a wide range of ESP contexts. It offers new theoretical and pedagogical insights for ESP practitioners and researchers alike, going beyond descriptions of ESP situations and programmes to bring in sound research design and data analysis which are firmly anchored in previous ESP research. The nine papers in this collection cover a variety of ESP domains, from medicine, technical science, and engineering to social sciences and the humanities, in order to encapsulate current trends and new developments in ESP teaching and learning research in Europe.
Pierres gravées de la Marche à Lussac-les-Châteaux (Vienne) : techniques, technologie et interprétations

Les creations artistiques du Magdalenien sont multiples et etonnamment riches. Dans le domaine de l'art mobilier, les pierres gravees jouent un role important pour l'iconographie de cette epoque et refletent ainsi de maniere tres representative la diversite et la complexite des representations magdaleniennes. Le site de la Marche, a Lussac-les-Châteaux (Vienne), date du Magdalenien moyen, est depuis sa decouverte connu pour ses pierres gravees; plusieurs chercheurs se sont essayes a leur dechiffrement et ont pu demontrer la presence de centaines de figurations. Des decouvertes recentes ont livre plus d'un millier de nouvelles pieces gravees. Le but de cette etude est de caracteriser ces supports, les gravures et les autres traces qui s'y trouvent. Mis a part la decouverte de nouvelles figurations gravees, il apparait en effet que ces pierres peuvent etre considerees comme des temoins des comportements des Magdaleniens ainsi que de leur pensee symbolique. Enfin, la mise a l'epreuve de nouveaux moyens d'investigation dans le cadre d'une methodologie adaptee aux supports montre son interet pour la comprehension, la valorisation et la conservation des objets prehistoriques.

Student Performance and Student Growth as Measures of Success: An Evaluator's Perspective.

Measuring the academic achievement of students at the extremes of a grade level distribution accurately poses challenges that may be compounded if a single-level assessment is used for each grade level. Multiple level of achievement measures, such as the Achievement Level Tests (ALT), can help overcome these challenges by increasing the accuracy of the obtained achievement estimate. ALTs provide increased accuracy by providing a measure that centers the score distribution around the student's knowledge level and by providing more items that are at an appropriate level of difficulty for the student. Ceiling and floor effects are less likely, and content validity and curriculum alignment are not at issue because the tests are custom designed to the school district's goal structure. Regression effects are less likely, and ALTs are more growth sensitive than single-level norm referenced tests. The Cherry Creek School District, Colorado, is one of approximately 20 districts in the state and more than 200 in the United States that are using ALTs. ALTS provide a means of addressing the measurement of achievement at the extremes that is necessary to make the new standards-based paradigm effective in improving public education.

The Use of Waste Biomass from the Wood Industry and Municipal Sources for Energy Production

Biomass can be used for the production of energy from renewable sources. Because of social resistance to burning crop plants, mixtures and pellets made from or including waste materials are a good alternative. The mixtures analyzed, prepared from wood and municipal waste, were characterized for their calorific values, 7.4–18.2 MJ·kg−1. A result, over 15 MJ·kg−1 was obtained for 47% of the quantities of mixtures being composed. It has been demonstrated that wood shavings and sewage sludge have a stabilizing effect on the durability of pellets. The emissions of acidic anhydrides into the atmosphere from the combustion of pellets from waste biomass were lower for NO, NO2, NOx and H2S than emissions from the combustion of willow pellets. Obtained emission results suggest the need to further optimize the combustion process parameters.

Weaknesses of wickedness: a critical perspective on wickedness theory

ABSTRACT It is attractive to frame societal challenges such as climate change, terrorism and migration as ‘wicked issues’. Wickedness theory in its various guises has become popular as it connects the uncertain and political nature of issues with hopeful strategies for strengthening networks, trust and learning. In this paper we take a critical approach towards wickedness, advancing three criticisms: (1) the daily experiences of people and their practices are missing from the grand narratives about wickedness, (2) the potential of collaborations and learning to address these problems is romanticized, (3) the implications for managerial and professional perspectives are unclear. We argue that the wickedness literature can be strengthened by further emphasizing situated relations, routines and rituals, adopting the perspective of situated wickedness. This would link insight into grand wickedness to insights into daily ambiguity. We illustrate this argument with two specific cases, (counter)terrorism and forced migration/refugees.
Effects of social, environmental, and institutional factors on sustainability report assurance: evidence from European countries

The purpose of this study is to extend existing knowledge on the determinants of sustainability report (SR) assurance practices. Four different theories – stakeholder theory, institutional theory, signaling theory and legitimacy theory – are used to formulate several hypotheses regarding the main factors that can influence a company’s decision to assure its SRs. ,Using a sample of 417 listed organizations based in different European countries over five years, the effects of stakeholder commitment, country orientation toward sustainability, firm environmental performance and business ethics controversies on the decision to assure SRs are assessed. ,The results show that a company’s decision to assure its SRs is motivated by the need to maintain good relations with its stakeholders (which is in line with stakeholder theory and legitimacy theory), as well as by the willingness to signal their sustainability performance (which is in line with signaling theory) and to gain legitimacy. On the contrary, business ethics controversies do not seem to be relevant to a company’s assurance practices. ,This paper provides new insights into the influence that social, environmental and institutional factors have on assurance strategies. New factors that previous research does not investigate – environmental performance, business ethics controversies and corporate governance – are tested. Factors that are already investigated in the literature are considered from an original perspective of introducing alternative measures (e.g. for the scope of national sustainability policies).
Effect of Total Quality Management Practices and JIT Production Practices on Flexibility Performance: Empirical Evidence from International Manufacturing Plants

This paper presents the results of an empirical study investigating the relationship between Total quality management (TQM) practices, Just-in-time (JIT) production practices, and flexibility performance in manufacturing companies. Correlation and regression analysis are applied to analyze the data collected from 280 manufacturing plants in 12 countries including China, Finland, German, Italy, Israel, Japan, Korea, Spain, Sweden, Taiwan, United Kingdom, and Vietnam from 2013 to 2015 in the framework of a High Performance Manufacturing Project. The analytical results confirm the closed linkage between TQM, JIT production practices and flexibility performance. Moreover, this study indicates that the effect of JIT production practices on flexibility performance can be strengthened with a higher level of TQM practices. The main findings of this study suggest that flexibility performance can be built up by implementing both TQM and JIT production practices, and TQM should be regarded as the platform to maximize the effect of JIT production on flexibility performance.
Comparing Occupational Therapy Students' Competency Scores: 2:1 versus 1:1 Fieldwork

Fieldwork is essential to occupational therapy students’ development of professional competencies. Fieldwork models using student-to-fieldwork educator ratios of 1:1 and 2:1 are widely used, however, quantitative research exploring differences in student competencies between these two models is scarce. The objective of this study was to determine if development of student competencies differ between 2:1 and 1:1 fieldwork models during an occupational therapy educational program. A retrospective study using two years of occupational therapy students’ competency ratings by fieldwork supervisors ( N = 95 students; N = 355 fieldwork events) was performed. The Competency Based Fieldwork Evaluation for Occupational Therapists tool was used to assess student competencies at each fieldwork rotation ( n = 5 placements). Independent samples t -tests were used to compare students’ scores during 1:1 and 2:1 placements. No significant differences were noted in student competencies following participation in 2:1 and 1:1 placements. It was concluded that students are equally well prepared for practice if they have 1:1 or 2:1 fieldwork experiences.
Role of Bradykinin in Mediating Vascular Effects of Angiotensin-Converting Enzyme Inhibitors in Humans

Background The angiotensin-converting enzyme (ACE) not only generates angiotensin II but is also the main enzyme that destroys bradykinin. It has been hypothesized, therefore, that bradykinin is involved in the vascular effects of ACE inhibitors. However, its contribution has never been demonstrated in humans because of the lack of specific bradykinin receptor antagonists. Methods and Results High-resolution ultrasound and Doppler were used to measure radial artery diameter and blood flow in 10 healthy volunteers. The vascular effects of the ACE inhibitor quinaprilat, the selective bradykinin B2-receptor antagonist icatibant, and their combination were determined at rest, during reactive hyperemia (with increased flow causing endothelium-mediated, flow-dependent dilation), and during sodium nitroprusside, causing endothelium-independent dilation. Neither icatibant nor quinaprilat affected arterial diameter or blood flow at rest. However, icatibant reduced flow-dependent dilation by 33%, and quinaprilat in.
Fatigue's Influence on Workload, Situation Awareness, and Performance in a Military Simulation of Combat

FATIGUE’S INFLUENCE ON WORKLOAD, SITUATION AWARENESS, AND PERFORMANCE IN A MILITARY SIMULATION OF COMBAT Carlotta M. Boone Old Dominion University, 2007 Director: Dr. James Bliss Military operations routinely require military personnel to consistently perform their duties over several hours or days. Tasks that require prolonged work can lead to mental fatigue and decreased performance. The transactional model proposes that individuals cope with changes in the environment and maintain performance. This ability to cope is determined by factors of the environment and the individual’s personality. One environmental factor that can influence coping is extended task performance. This study examined the effect of extended task performance and its interaction with task difficulty. Participants interacted with the military simulation game Command and Conquer: Generals TM for three hours. They were assigned to either the easy or difficult level of the game. Extended task performance led to an increase in feelings of fatigue. However, it also led to a decrease in mental workload. Contradictory findings were found for situation awareness. Performance on the item measuring perception decreased while performance on items measuring prediction increased. Participants’ game performance increased in that they killed more opposers and lost less of their own troops over time. Participants in the difficult group experienced more fatigue than those in the easy group. Task difficulty had no significant interaction with time spent on the task. This study extends current knowledge by providing evidence for the effect of time-on-task fatigue in relation to mental workload, situation awareness, and performance.

Providing quantifiable data about when and to what extent time-on-task fatigue influences performance can provide a framework for additional training measures. Additionally, the data collected implicate that performance can improve over time; particularly if the task is continuous, participants have past experience with it, and are motivated to continue performing the task.

Clinical screening for heart disease in apparently healthy Nigerian school children

Background: Heart diseases of childhood are of public health importance, especially in developing countries. Community-based studies are important in ascertaining the burden of disease. We set out to clinically evaluate the prevalence of heart disease among primary school children in Hwolshe electoral Ward, Jos, Plateau State. Subjects and Methods: A total of 418 primary school pupils were selected by multistage sampling from three schools in Hwolshe ward of Jos South Local Government Area, Plateau State. They were studied for the prevalence of heart disease using clinical examination, followed by chest radiography, electrocardiography and echocardiography (echo) in those with clinical signs of heart disease. Results: The 418 subjects were aged 6-12 (mean 9.0 ± 1.95) years. 252 (55.5%) were girls. Significant tachycardia and pulse irregularity were present in 1 (0.24%) and 3 (0.72%) children respectively. None had hypertension - according to the seventh Joint National Committee criteria. 4 (0.96%) had audible murmurs of which 3 (0.72%) were pathologic. These three subjects were subsequently confirmed by echo to have congenital heart disease (CHD) - two ventricular septal defects and one atrial septal defect. The heart disease prevalence was therefore, 0.72%. All three identified cases of CHD had associated cardiac dysrhythmias: Wandering atrial pacemaker, first degree heart block, and incomplete right bundle branch block, respectively. No case of rheumatic heart disease was identified. Conclusions: Prevalence of heart disease by clinical screening in Jos South school children is approximately 0.72%. Careful cardiac auscultation as part of compulsory health screening at primary school entry and exit will help detect asymptomatic children with heart disease and facilitate treatment before the onset of complications.
